Vacuum Cleaning Device
Disclosed is a computer-implemented, self-controlling vacuum cleaning device for cleaning soft surfaces without human intervention. The device comprises a plurality of rotary cleaning heads, each of which extending through a chassis beyond a bottom surface thereof, the plane of rotation of each cleaning head being parallel to said bottom surface. Each cleaning head comprises a plurality of spray heads for dispensing pressurized cleaning solution onto the cleaning surface and a plurality of suction heads for suctioning the cleaning solution along with the impurities absorbed by it. The device further comprises a computer controller for virtually mapping a cleaning pattern on the cleaning surface and for propelling the device as per the cleaning pattern.
The present invention relates to a domestic cleaning system. More specifically, the present invention relates to a vacuum cleaning device which allows a user to clean soft surfaces without requiring the user to manually operate the same.
Vacuum cleaners are widely used for hassle-free cleaning purposes. The components of the vacuum cleaner include an electric motor as a suction source for the vacuuming purpose, for example, dust particles and particulates that are normally settled down on the floor, carpet, table, etc. In order to supply the electric power, the power cords are connected to the electric mains. Once the vacuum cleaner no longer requires to be connected to the mains, the power cord is wound into the vacuum cleaner so that, the vacuum cleaner can be easily packed.
There are many conventional vacuum cleaners which are designed to reduce a considerable amount of space as well, as in the household use, where the vacuum cleaners are known which have a cord-winding mechanism in the casing of the vacuum cleaner. This internal cord-winding mechanism, which often incorporates a mechanical winding assistance unit, tremendously reduces the useful space of the vacuum cleaner. However, most of such vacuum cleaners have a main issue, where the user themselves have to manually operate the device to clean the surfaces. There are no sensory means present in the conventional vacuum cleaners which provide detection of sections which need to be cleaned. Further, with the advent of smart phone technology and other such smart devices, there is no vacuum cleaner in the market which is integrated along with such smart devices to enable automation of the working.
Currently, commercial carpet cleaners come with one or two heads and are used under manual operator control. The rotating heads allow the product to be move fore and aft or laterally side to side by manipulating the handle and the tilt of the heads. The conventional vacuum cleaners are heavy and when connected to the hoses, they are somewhat cumbersome to use. It takes considerable experience to operate the conventional vacuum cleaners under good control and, by the end of the shift; the user is typically very fatigued. Additionally, the heavy conventional vacuum cleaners can get away from the operator and crash into the wall or trim boards, requiring costly repairs that drain the profit from the job. Therefore, there is a need for an automated vacuum cleaning device which can address above mentioned issues.
SUMMARYAn embodiment of the present invention is directed to a computer-implemented, self-controlling vacuum cleaning device, which is intended for operational deployment on soft surfaces, especially those that pertain to carpets, floor mats, rugs, and the like. The device is computer implemented to the point that it doesn't require manual intervention for its operation right from start to finish. More specifically, the device propels itself over the soft surface in a pattern that is determined by the device itself.
The device comprises a chassis and an outer shell sealingly fitted on top of the chassis wherein, almost every component of the device is disposed between chassis and the outer shell. The device is powered by a retractable power cord residing therewithin wherein, the power cords connects the device to an electrical wall socket. The chassis is a flat, substantially rectangular member with the corners thereof being rounded. Four substantially circular holes disposed on the chassis extend from the top to the bottom surface thereof. More particularly, two holes (which hereinafter are referred to as front holes) are disposed closer to the front edge of the chassis, while the remaining two holes (which hereinafter are referred to as rear holes) are disposed closer to the rear edge of the chassis. Notably, the centers of the front and rear holes are laterally aligned and the pairs of front and rear holes closer to the side edges are longitudinally aligned. Each hole is adapted to receive a rotary cleaning head, which is pre-fitted within a bell-shaped casting that is preferably made of aluminum. The assembly between the bell-shaped casting and chassis is configured such that, upon the reception of a bell-shaped casting within a hole, the cleaning head extends slightly beyond the bottom surface of the chassis. The plane of rotation of a cleaning head is parallel the bottom surface of the chassis.
The cleaning head comprises a three suction heads extending radially from the center (of the cleaning head) such that, the angle between two successive cleaning heads is equivalent. As viewed from bottom, each suction head is elongated and substantially rectangular with a central, substantially rectangular opening through which, dirt is suctioned during the operation of the device. Notably, the mid portion of the suction head (as viewed from bottom) is slightly curved. The suction heads are disposed in fluid communication with a suction chamber via a vacuum hose. Notably, the suction chamber is a part of the cleaning head and therefore, resides within the corresponding bell-shaped casting. Each suction chamber is in turn disposed in fluid communication with a plenum via another vacuum hose. An external vacuum hose removably accessing the plenum from the rear of the device facilitates the discharge of the dirt collected over time within the plenum.
The cleaning head further comprises three spray heads, each of which disposed between two successive suction heads. Notably, the angle between two successive spray heads with respect to the center is equivalent. The spray heads are configured to discharge pressurized cleaning solution therefrom. The cleaning solution is supplied from an external source via an external solution hose connecting said source and the rear of the device. The solution is received by a self-supporting rotating union. The rotating union, as enabled by a DC solenoid, allocates the solution to the four cleaning heads. The device is operationally configured such that, first, the solution is discharged from the spray heads whereafter, the solution mixed with the dirt is suctioned by the suction heads.
The device further comprises three distance sensors viz., a front and two side distance sensors. The front distance sensor is mounted at the front of the device, while the side distance sensors are mounted at the sides of the device. More particularly, the distance sensors are mounted on the outer shell. Each distance sensor is for calculating the distance between itself (which is translated into the device) and an obstacle in the line of sight thereof. The obstacle could be a wall or any object that blocking the vision of the sensor.
The device further comprises a computer controller for controlling the operation thereof. The computer controller comprises a user interface for enabling a user to interact therewith. The computer controller further comprises a mapping and a motion module, the utility of each of which will become apparent from the following body of text. Upon the device being placed on a cleaning surface and powered on via the user interface, the computer controller is configured to initially measure the distance between the device and the obstacles that lay ahead and sideways. The distance sensors are disposed in operational conjunction with the mapping sensor whereby, the mapping module, based on the calculations obtained from the distance sensors, virtually creates a cleaning pattern on the cleaning surface. The motion module propels the device in the cleaning pattern. Along the cleaning pattern on the cleaning surface, the cleaning solution is sprayed thereon and consecutively worked thereinto. Once the cleaning solution is worked in, the emerging solution mixed with impurities are suctioned by the suction heads, which is then transferred into the suction chambers and ultimately into the common plenum.
Other features and advantages will become apparent from the following description of the preferred embodiments, taken in conjunction with the accompanying drawings.
