CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of international application number PCT/EP2011/053401, filed on Mar. 7, 2011, which is incorporated herein by reference in its entirety and for all purposes.

BACKGROUND OF THE INVENTION

The invention relates to a mobile high-pressure cleaning device with an underframe, on the upper side of which a storage section is arranged which forms a motor receptacle, into which a motor is inserted for driving a pump, wherein a holding section fixing the motor in place in the motor receptacle is placed onto the storage section and has a storage compartment for electric parts on its upper side facing away from the motor.

A high-pressure cleaning device of this type is known from the document EP 0 921 869 B1. This high-pressure cleaning device is designed like a sack barrow, wherein the motor and a pump secured to it are aligned at an angle to the vertical. The motor is accommodated by a shell-like housing section which essentially has the shape of a semi-circular cylinder and is open towards the front side. The longitudinal axis of the semi-cylindrical housing section is aligned at an angle to the vertical. A cover is placed onto the shell-like housing section and this cover has the shape of a semi-circular cylinder, like the housing section, and covers the motor. Holding arms projecting outwardly from the motor are accommodated by recesses which are integrally formed in the edges of the housing section and the cover which face one another. On its outer side in an upper end area, the cover has a chamber which serves to accommodate electric parts, for example connecting elements and switch elements.

The object of the present invention is to develop a mobile high-pressure cleaning device of the generic type further in such a manner that it has a construction which is structurally simpler and mechanically more stable.

SUMMARY OF THE INVENTION

This object is accomplished in accordance with the invention, in a mobile high-pressure cleaning device of the type specified at the outset, in that the holding section is designed as a hollow body with a base member and a cover mounted on the base member, wherein the base member forms the storage compartment with a base wall engaging over the motor and with side walls which project upwards from the base wall, and wherein the cover is movable back and forth between a closed position closing the storage compartment and an open position giving access to the storage compartment and has at least one actuating member for an electric control element on its outer side facing away from the storage compartment.

In the case of the high-pressure cleaning device according to the invention, the holding section engaging over the motor has not only the function of securing the motor in the motor receptacle but the holding section also has the function of an electric box, in which electric parts of the high-pressure cleaning device, in particular electric control elements, are arranged. The electric box is designed in the shape of a storage compartment and comprises a base wall engaging over the motor and side walls which project upwards from it. This results in a mechanical reinforcement of the holding section which conveys a high mechanical stability to the high-pressure cleaning device. The storage compartment is covered by a cover which is mounted on the base member of the holding section so as to be movable. The cover can be moved back and forth between a closed position which closes the storage compartment and an open position which gives access to the storage compartment. On its outer side, the cover has at least one actuating member for an electric control element which can be actuated by the user. The control element can be arranged in the storage compartment and wired to additional electric parts which are arranged in the storage compartment. It may be provided, in particular, for an electric control element, for example a switch element, to be fixed to the inner side of the cover and wired to additional electric parts which are secured to the base wall of the storage compartment. The wiring of the electric parts and the at least one electric control element can be brought about before the complete holding section is placed onto the storage section. This makes the assembly of the high-pressure cleaning device easier and, therefore, also improves its production costs.

It is of advantage when the storage compartment extends from a first supporting surface of the storage section at least as far as a second supporting surface of the storage section, wherein the motor receptacle is arranged between the two supporting surfaces. The storage compartment can, as a result, have a large storage volume. A first side wall of the storage compartment can be arranged, for example, above the first supporting surface of the storage section and a second side wall of the storage compartment can be at a distance from the first side wall which is at least as large as the distance between the two supporting surfaces of the storage section, between which the motor receptacle is arranged.

It is of particular advantage when the storage compartment extends from the first supporting surface of the storage section to beyond the second supporting surface of the storage section. The storage compartment is, therefore, designed to be bigger than the distance between the two supporting surfaces, between which the motor receptacle is arranged. This gives the storage compartment a particularly large storage volume and so a large number of electric parts can be positioned in the storage compartment. The electric parts can, in this respect, be spaced from one another at a distance which counteracts any overheating of the electric parts.

The storage compartment favorably has, in the plan view, the shape of a polygon, in particular the shape of a rectangle, and comprises two side walls which are aligned parallel to the motor axis and two aligned at right angles to the motor axis as well as the base wall which engages over the motor. The arrangement of the side walls parallel and at right angles to the motor axis provides the base member of the holding section with a high mechanical stability.

In order to be able to cool the motor effectively during operation of the high-pressure cleaning device, the motor is, in one advantageous embodiment of the invention, surrounded by a ring-shaped cooling air duct which extends between the motor housing, on the one hand, and the holding and storage sections, on the other hand. Both the storage section and the holding section are, therefore, at a distance from the motor housing. As a result, cooling air can be conveyed along the motor housing in order to cool the motor effectively.

The motor preferably has holding arms which project outwards from the motor housing and are accommodated in recesses which are integrally formed in supporting surfaces of the storage section and the holding section.

The holding section can preferably be releasably connected to the storage section and the underframe. It may be provided, for example, for the holding section to be releasably connected to the storage section on a first side of the motor receptacle and to the underframe on a second side of the motor receptacle. This gives the storage section and the underframe a high mechanical stability in the region of the motor receptacle.

It may be provided for the base member of the holding section to have supporting feet and for supporting foot receptacles, into which the supporting feet can be inserted, to be arranged in the storage section and in the underframe. In such a configuration, at least one supporting foot of the base member will be accommodated by a supporting foot receptacle of the storage section and at least one further supporting foot of the base member will be accommodated by a supporting foot receptacle of the underframe.

It is favorable when the supporting feet of the base member can be screwed to the storage section and/or to the underframe.

The storage section is, in one advantageous development of the invention, integrally formed on the underframe. In this respect, the storage section and the underframe can be produced from plastic.

In one preferred configuration, the storage section has two double-walled supporting members, between which the motor receptacle is arranged. The supporting members can each comprise an inner wall and an outer wall which are connected to one another in one piece via an end wall. The end walls can form supporting surfaces for supporting the motor positioned in the motor receptacle. The inner walls of the supporting members are preferably connected to one another in one piece via a base wall of the motor receptacle. The base wall of the motor receptacle is favorably curved in an arc shape at least in sections.

It is favorable when the underframe has a frame lower section produced from plastic and a frame upper section produced from plastic, wherein the frame upper section forms the storage section and is connected to the frame lower section in a materially joined manner. It may be provided, for example, for the frame upper section to be welded to the frame lower section. The frame upper section can form the storage section on its upper side facing away from the frame lower section, with a motor receptacle which is upwardly open. The motor can be inserted into the motor receptacle. Subsequently, the holding section can be placed onto the motor and secured to the storage section.

The motor axis of the motor is preferably aligned at right angles to the direction of travel of the high-pressure cleaning device. A horizontal longitudinal axis of the high-pressure cleaning device defines the direction of travel of the high-pressure cleaning device and the motor axis is favorably aligned at right angles to the longitudinal axis. This makes a particularly compact construction of the mobile high-pressure cleaning device possible.

The high-pressure cleaning device has, in one preferred configuration, a heat exchanger, with the aid of which the cleaning fluid, i.e., in particular water, which is conveyed by the high-pressure cleaning device can be heated. The underframe has for this purpose a recess, into which the heat exchanger can be inserted. The recess is favorably arranged in the direction of travel behind the storage section which provides the motor receptacle.

As already mentioned, the cover of the storage section can be moved back and forth between a closed position and an open position. The cover is favorably mounted on the base member so as to be pivotable about a first pivot axis aligned parallel to the motor axis. This facilitates repair and maintenance work on the high-pressure cleaning device, during which access to the storage compartment of the holding section is necessary.

The high-pressure cleaning device preferably comprises a hood which is mounted on the underframe so as to be pivotable about a second pivot axis and has a hood opening which, in a closed position of the hood, gives access to the at least one actuating member arranged on the outer side of the cover of the holding section. The hood can be pivoted back and forth between a closed position, in which it covers the holding section and the motor as well as additional components of the high-pressure cleaning device, for example a heat exchanger, and an open position, in which it gives access to the holding section, the motor and other components of the high-pressure cleaning device. The hood has a hood opening and so in the closed position of the hood the at least one actuating member arranged on the outer side of the cover of the holding section is accessible to the user. A main switch can, for example, be arranged on the cover of the holding section or, when the high-pressure cleaning device according to the invention is designed as a heatable high-pressure cleaning device, a temperature regulator, with which the temperature of the cleaning fluid subjected to pressure and discharged from the high-pressure cleaning device can be predetermined.

It is favorable when an actuating member in the form of a movable handle for an electric switch, in particular for a rotary switch, is arranged on the outer side of the cover of the holding section, wherein the cover forms a bearing element for the handle. A rotary switch can comprise, for example, a shaft which can be inserted into a bearing sleeve of the cover. This facilitates the assembly of the rotary switch which can, for example, be designed as the main switch of the high-pressure cleaning device. The bearing sleeve forms a bearing element for the handle of the rotary switch.

In one advantageous embodiment, the cover defines an accessory compartment on its outer side. The accessory compartment can be designed in the form of a recess and enables the user to take along accessory parts of the high-pressure cleaning device with the mobile high-pressure cleaning device. The accessory compartment can favorably be covered by a hood of the high-pressure cleaning device. As a result, accessory parts are prevented from becoming lost.

It is of particular advantage when the base member of the holding section comprises a valve holder, on which a metering valve is held. The adding of a chemical to the cleaning fluid conveyed by the high-pressure cleaning device can be metered by means of the metering valve. A cleaning agent can be used, for example, as the chemical which can be mixed with the cleaning fluid, in particular water. For this purpose, the underframe of the high-pressure cleaning device favorably forms a cleaning agent tank, in which the cleaning agent can be stored.

As already mentioned, the high-pressure cleaning device can comprise a pivotable hood. It is favorable when the hood has a hood opening, via which an actuating member of the metering valve is accessible to the user in the closed position of the hood.

The following description of a preferred embodiment of the invention serves to explain the invention in greater detail in conjunction with the drawings.

DETAILED DESCRIPTION OF THE INVENTION

A mobile high-pressure cleaning device according to the invention is illustrated schematically in FIG. 1 and, in the embodiment illustrated, is designed in the form of a heatable high-pressure cleaning device and is given, altogether, the reference numeral 10. It comprises an underframe 12 with a frame lower section 13 and a frame upper section 14 which are produced from plastic and welded to one another. For the purpose of moving the high-pressure cleaning device 10, this has wheels, wherein a rear wheel 15 and a steerable, front wheel 16, which are mounted on the underframe 12, are apparent in the drawings.

The high-pressure cleaning device 10 comprises a housing 18 with a housing base 19 which is held immovably on the upper side of the underframe 12 and a hood 20 which is mounted on the underframe 12 so as to be pivotable and can be moved back and forth between a closed position illustrated in FIG. 1 and an open position illustrated in FIG. 2.

The high-pressure cleaning device 10 comprises an electric motor 22, with which a pump, which is not illustrated in the drawings, can be driven for conveying a cleaning fluid, in particular for conveying water. The electric motor 22 is arranged in a shell-like motor receptacle 23 which is formed by a storage section 25 which is connected in one piece to the frame upper section 14 of the underframe 12. As is apparent, in particular, from FIG. 5, the storage section 25 comprises a first supporting member 27 and a second supporting member 28 which is arranged at a distance thereto in the direction of travel 30 of the high-pressure cleaning device 10. The supporting members 27, 28 are of a double-walled design. They have outer walls 29, 31 which face away from one another and inner walls 32, 33 which face one another. The latter are connected to one another in one piece via a base wall 26 of the motor receptacle 23 which is, in sections, of an arc-shaped design. The first supporting member 27 defines a first supporting surface 34 with an end wall facing away from the underframe 12 and the second supporting member 28 defines a second supporting surface 35 with an end wall facing away from the underframe 12. The supporting surfaces 34 and 35 are of a flat design and each have semi-cylindrical recesses 36 and 37, respectively. Holding arms 40 which project outwards from a motor housing 39 of the electric motor 22 can be inserted into the recesses 36 and 37 so that the electric motor 22 is supported by the supporting members 27 and 28 of the storage section 25 via the holding arms 40, wherein the motor housing 39 is at a distance from the inner walls 32, 33 and from the base wall 26 of the motor receptacle 23.

The frame upper section 14 of the underframe 12 forms, in front of the second supporting member 28 in the direction of travel 30 and at a distance from the second supporting member 28, a panel 42 which extends parallel to the second supporting member 28 and bears on its upper side 43 facing away from the underframe 12 two supporting foot receptacles 45, 46 which are spaced from one another, are of a U-shaped design and each have two aims 48, 49 which project upwards from the upper side 43 and are connected to one another in one piece at their free ends via a web 50.

Two further supporting foot receptacles 53, 54 are arranged on the first supporting surface 34 but these are not of a U-shaped design but merely have two supporting sides 56, 57 which project upwards from the first supporting surface 34. The first supporting surface 34 has each time, between the supporting sides 56 and 57, a bore 58, into which a connecting screw can be screwed. This will be explained in greater detail in the following.

The electric motor 22 positioned in the motor receptacle 23 is covered by a holding section 60. The holding section 60 is designed as a hollow body and comprises a base member 61 and a cover 65 mounted on it so as to be pivotable about a first pivot axis 63. The cover 65 can be pivoted back and forth between an open position, which is illustrated in FIG. 2 and in which it gives access to a storage compartment 67 for electric parts of the high-pressure cleaning device 10 which is defined by the base member 61, and a closed position which is illustrated in FIG. 3 and in which it closes the storage compartment 67.

The base member 61 of the holding section 60 has a base wall 69 which engages over the electric motor 22 at a distance from the motor housing 39. Side walls, which give the storage compartment 67 an essentially rectangular contour in the plan view, project from the base wall 39 directed vertically upwards. A first side wall 71 extends above the first supporting member 27 and a second side wall, which is aligned parallel to the first side wall 71, extends above the panel 42 formed by the underframe 12. The first side wall 71 and the second side wall 72 are connected to one another in one piece via a third side wall 73 and a fourth side wall 74 arranged at a distance from the third side wall 73. A motor axis 76 of the electric motor 22 is aligned at right angles to the direction of travel 30 and the first side wall 71, the second side wall 72 as well as the first supporting member 27, the second supporting member 28 and the panel 42 extend parallel to the motor axis 76. The third side wall 73 and the fourth side wall 74 are aligned at right angles to the motor axis 76.

The second side wall 72 bears on its outer side facing away from the storage compartment 67 a valve holder 78, on which a metering valve 80 is held. With the aid of the metering valve 80 the addition of a cleaning agent to the cleaning fluid conveyed by the pump of the high-pressure cleaning device 10 can be metered. The metering valve 80 has an actuating member in the form of a valve handle 82, with which the user can adjust the metering valve 80.

The cover 65 of the holding section 60 has above the electric motor 22 a recess which defines an accessory compartment 81, in which accessory parts of the high-pressure cleaning device 10 can be positioned. In the region between the accessory compartment 81 and the metering valve 80, the cover 65 has an operating panel 83 aligned at an angle to the vertical, with a bearing sleeve 84 passing through the cover 65. Passing through the bearing sleeve 84 is a switching shaft of a rotary switch (not illustrated in the drawings) arranged on the inner side of the cover 65; the switching shaft is known per se and not, therefore, illustrated in the drawings. The rotary switch forms an electric switching element, with which the high-pressure cleaning device 10 can be controlled. In the embodiment illustrated, the rotary switch is designed as a main switch of the high-pressure cleaning device 10. For the purpose of actuating the rotary switch, an actuating member in the form of a switching handle 86 can be placed on the bearing sleeve 84 and can be connected non-rotatably to the switching shaft passing through the bearing sleeve 84.

The hood 20 is pivotable about a second pivot axis 88 aligned parallel to the first pivot axis 63. This is apparent, in particular, from FIG. 2. The hood has, at a distance from the second pivot axis 88, a first hood opening 91 which has the valve handle 82 of the metering valve 80 passing through it in the closed position of the hood 20 so that the user can adjust the metering valve 80 in the closed position of the hood 20 with the aid of the valve handle 82.

Contrary to the direction of travel 30 at a distance from the first hood opening 91, the hood 20 has a second hood opening 95 which allows a user access to the operating panel 83 and the switching handle 86 arranged thereon in the closed position of the hood 20. The edge of the second hood opening 95 corresponds to the contour of the operating panel 83.

Contrary to the direction of travel 30 at a distance from the second hood opening 95, the hood 20 has a third hood opening 97. An exhaust pipe 99 of a fuel-operated heat exchanger, which is known per se and not, therefore illustrated in the drawings in order to achieve a better overview, opens into the third hood opening 97. The heat exchanger can be positioned in a recess 101 of the underframe 12. The recess 101 is arranged, in the direction of travel, behind the storage section 25 which accommodates the electric motor 22.

In order to secure the holding section 60 on the storage section 25, the base member 61 of the holding section 60 has two rear supporting feet 103, 104 and two front supporting feet 106, 107. The rear supporting feet 103, 104 are arranged above the first supporting member 27 and can be inserted into the supporting foot receptacles 53 and 54, respectively, of the first supporting surface 34. The rear supporting feet 103, 104 can be screwed to the first supporting member 27 by means of connecting screws not illustrated in the drawings.

The front supporting feet 106, 107 are arranged above the panel 42 of the underframe 12 and can be inserted into the supporting foot receptacles 45 and 46, respectively, of the panel 42. The front supporting feet 106 and 107 each have, for this purpose, a front supporting foot section 109 and 110, respectively, which can be pushed into the U-shaped supporting foot receptacles 45 and 46, respectively. This facilitates the assembly of the base member 61 since, in a first assembly step, the front supporting feet 106, 107 can be positioned on the panel 42 in such a manner that the front supporting foot sections 109, 110 can be pushed into the supporting foot receptacles 45, 46. Subsequently, the rear supporting feet 103, 104 can then be inserted into the supporting foot receptacles 53, 54 of the first supporting member 27 and be screwed to the first supporting member 27. As a result, only two connecting screws are required for the releasable attachment of the holding section 60 to the underframe 12 and to the storage section 25.

As already mentioned, electric parts can be positioned in the storage compartment 67 of the holding section 60, in particular control parts for controlling the electric motor 22 and for controlling a fuel pump which is known per se and not, therefore, illustrated in the drawings and with the aid of which liquid fuel can be supplied to a burner of the heat exchanger which is not illustrated in the drawings. Electric parts can also be fixed to the inner side of the cover 65 once the cover 65 has been pivoted into its open position. All the electric parts can be wired to one another before the holding section 60 is placed on the storage section 25. The assembly of the holding section 60 on the storage section 25 can be brought about once the electric motor 22 has been inserted into the motor receptacle 23. The holding arms 40 projecting from the motor housing 39 are supported in the recesses 36 and 37 of the two supporting members 27, 28. For the purpose of securing the electric motor 22 to the storage section 25, rear supporting walls 112, 113 and front supporting walls 115, 116 project from the underside of the base wall 69 of the base member 61 and these supporting walls have at their free ends recesses 118 and 119, respectively, which interact with the recesses 36 and 37 of the two supporting members 27 and 28 and accommodate the holding aims 40 of the electric motor 22. The rear supporting walls 112, 113 are each arranged on one side of the rear supporting feet 103, 104 and are supported on the first supporting member 27. The front supporting walls 115, 116 are arranged behind the front supporting feet 106, 107 with respect to the direction of travel 30 of the high-pressure cleaning device 10 and are supported on the second supporting member 28. The holding section 60 protrudes beyond the second supporting member 28 in the direction of travel 30 and so the storage compartment 67 has a large interior volume for accommodating the electric parts.

The holding section 60, which is secured, on the one hand, to the panel 42 of the underframe 12 and, on the other hand, to the first supporting member 27, conveys a high mechanical stability to the high-pressure cleaning device 10. This is ensured, in particular, by the configuration of the holding section 60 in the form of a hollow body which comprises a base wall 69 engaging over the electric motor 22 and side walls 71 to 74 projecting from it vertically upwards. In combination with the inner walls 32, 33 of the supporting members 27, 28 and the base wall 26 of the storage section 25, the base wall 69 of the holding section 60 forms a cooling air guiding wall which limits a ring-shaped cooling air duct 121 which surrounds the electric motor 22 in circumferential direction. This makes an effective cooling of the electric motor 22 possible by means of cooling air which is guided through the cooling air duct.
