This application claims the benefit, under 35 U.S.C. § 119, of Chinese patent application CN 201621270853.8, filed Nov. 25, 2016; the prior application is herewith incorporated by reference in its entirety.
BACKGROUND OF THE INVENTION Field of the InventionThe present invention relates to the field of cooling technologies, and in particular, to a cooling appliance including a water path component.
German patent DE 112006000552, corresponding to U.S. Pat. No. 7,810,345, describes a cooling device with a liquid delivery system that is used for user equipment. The liquid delivery system has a protection system, to avoid an overflow resulting from possible liquid leakage.
SUMMARY OF THE INVENTIONAn objective of the present invention is to provide a cooling appliance that can mechanically isolate a circuit component from a water path component having a potential water leakage threat, so that the circuit component of the cooling appliance can be protected to a large extent, avoiding possible adverse consequences of electric leakage or short circuits.
The objective is achieved by the subject having the characteristics described in the independent claims. Beneficial embodiments of the present invention form the subject of the accompanying drawings, the specification, and the dependent claims.
According to an aspect of the present invention, the objective is achieved by using a cooling appliance, including: a water path component for supplying water; and a circuit component for supplying electricity or transmitting a control signal. An isolation component is disposed between the water path component and the circuit component to mechanically isolate the water path component from the circuit component.
Therefore, for example, an achieved technical advantage is as follows: The isolation component is disposed between the water path component and the circuit component, so that when water is leaked from the water path component, the leaked water is blocked by the isolation component from spraying and scattering or from splashing to the circuit component, avoiding adverse consequences of electric leakage or short circuits caused by undesired contact between the circuit component and the water.
The cooling appliance should be construed as, especially, a household cooling appliance, that is, a cooling appliance used for housekeeping in the domestic or catering application. The cooling appliance is especially used to store food and/or drinks at a particular temperature, for example, a refrigerator, a freezer, a fridge freezer, or a wine cooler.
The water path component refers to, especially, a component for holding or controlling flow of water in a water path system of the cooling appliance, for example, a water pipe, a switch, or various water valves.
The circuit component should be construed as a component in the cooling appliance for bearing electricity transmission, supplying electricity, or transmitting a control signal, and is especially an integrated or a modular component such as a power supply circuit board, a display circuit board, or a control circuit board.
In a preferred embodiment, the isolation component is configured as a cover for at least partially covering the circuit component. Therefore, for example, achieved technical advantages are as follows: Water leaked from the water path component is blocked by the cover from coming into contact with the circuit component. In addition, the cover needs to cover only a part or a surface of the circuit component that may be in contact with the leaked water rather than completely cover or wrap the entire circuit component.
In a preferred embodiment, the cover at least covers a part or a surface of the circuit component that may be in contact with water leaked from the water path component. Therefore, the cover does not need to completely cover or wrap the entire circuit component.
In a preferred embodiment, the cover is slidably installed on the circuit component by using a guide mechanism, and the guide mechanism includes a guide rib and a guide slot that cooperate with each other. Therefore, for example, achieved technical advantages are as follows: The guide mechanism facilitates the assembly of the cover to the circuit component, and a production process is simple or the cover is easy to remove, facilitating maintenance of the circuit component.
In a preferred embodiment, the isolation component is configured as a housing for at least partially surrounding the water path component. Therefore, for example, an achieved technical advantage is as follows: When water is leaked from the water path component, the water is blocked by the housing and kept inside the housing from coming into contact with the circuit component.
In a preferred embodiment, the water path component includes a valve body and a water pipe connected to the valve body, and the housing at least surrounds a part connecting the valve body and the water pipe. Therefore, for example, an achieved technical advantage is as follows: The housing needs to surround and wrap only a part of the valve body from which water is easily leaked or a connecting point between the valve body and the water pipe due to a high water leakage possibility of the connecting point rather than surround and wrap the entire water pipe or the valve body.
In a preferred embodiment, the valve body includes a functional valve and a check valve, and the check valve is serially connected to the functional valve by using the water pipe.
In a preferred embodiment, the housing includes a first housing and a second housing buckled with each other.
In a preferred embodiment, the circuit component is connected to an external power source.
In a preferred embodiment, the water path component and the circuit component are disposed in a same cavity.
In a preferred embodiment, the cavity serves as a compressor compartment of the cooling appliance; a compressor, a fan, and a condenser of the cooling appliance are disposed in the compressor compartment; and the circuit component is electrically connected to the compressor and the fan separately.
Other features which are considered as characteristic for the invention are set forth in the appended claims.
Although the invention is illustrated and described herein as embodied in a cooling appliance, it is nevertheless not intended to be limited to the details shown, since various modifications and structural changes may be made therein without departing from the spirit of the invention and within the scope and range of equivalents of the claims.
The construction and method of operation of the invention, however, together with additional objects and advantages thereof will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings.
The following clearly and completely describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are merely some but not all of the embodiments of the present invention. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
Referring now to the figures of the drawings in detail and first, particularly to
Purified water flows into a check valve 31 through a water inlet pipe 14, and then flows into a functional valve 15 through the water inlet pipe 14. In an embodiment, the functional valve 15 is a water valve having one inlet and two outlets, and the functional valve 15 is connected to two water outlet pipes, which are respectively a water outlet pipe 16 and a water outlet pipe 17. The water outlet pipe 16 is used to supply water to an ice-making machine 20, and the water outlet pipe 17 is used to supply water to a water storage tank 24. In an embodiment, the water outlet pipe 16 is connected to an inlet nozzle 19 by using a pipe joint 18, so that purified water may be supplied to the ice-making machine 20 by using the inlet nozzle 19. In a specific embodiment, the inlet nozzle 19 is disposed in a freezing compartment of the refrigerator 100. The ice-making machine 20 includes an ice-making unit 21 and an ice storage unit 22. A discharge outlet for discharging ice is disposed at a front end of the ice storage unit 22, and the ice storage unit 22 includes an ice discharge apparatus 23 for pushing the ice to the discharge outlet. In a specific embodiment, the ice discharge apparatus 23 includes a screw rod (not shown in the figures) and a motor for driving the screw rod (not shown in the figures).
In an embodiment, the water outlet pipe 17 is directly connected to an inlet end of the water storage tank 24. In a specific embodiment, the water storage tank 24 is disposed in the refrigeration compartment of the refrigerator 100, to store potable water that has been filtered. In an embodiment, the water storage tank 24 is connected to a pipeline 25, and the pipeline 25 is connected to an outlet nozzle 27 by using a pipe connector 26. The outlet nozzle 27 has a tail end disposed towards an allocation cavity of an allocator (not shown in the figures), to allocate water to an external container 28.
Because internal space of the cavity 101 is limited, the water path component 105 and the circuit component 106 are both disposed in the cavity 101 and are close to each other. Therefore, when water is leaked from the water path component 105, the leaked water is easy to spray and scatter to the circuit component 16 nearby, resulting in adverse consequences of electric leakage or short circuits caused due to contact between the circuit component 16 and the water. This is also one of key technical problems to be resolved in the present invention.
To resolve the foregoing technical problem, an isolation component is disposed between the water path component 105 and the circuit component 106, to mechanically isolate the water path component 105 from the circuit component 106 in the narrow space of the cavity 101. Therefore, the circuit component 106 cannot be in contact with the water leaked from the water path component 105.
In a process in which the cover 40 is covered on the circuit component 106, the cover 40 is slidably installed on the circuit component 106 by using a guide mechanism. The guide mechanism includes a guide rib 51 and a guide slot 52 that cooperate with each other. Specifically, the guide rib 51 is disposed on the circuit component 106, and the guide slot 52 is provided on the cover 40. In a process in which the cover 40 is slidably installed on the circuit component 106, the guide rib 51 slides into the guide slot 52, and engagement with each other occurs, so that the cover 40 is installed on the circuit component 106 more easily or is removed from the circuit component 106 more easily.
