Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an upright-type cleaning device that supplies foamed detergent foam to brush carpets, etc. when cleaning carpets, etc. The present invention relates to an upright-type cleaning device that supplies foamed detergent foam to brush carpets and the like, and operates a fan motor only during cleaning to remove the detergent foam. is supplied to the floor brush nozzle, and the floor brush nozzle automatically stops when the brush nozzle is removed from the floor surface even when not in use or during cleaning, thereby preventing wasted detergent due to unnecessary detergent foaming and saving power. Also, it prevents unfoamed detergent liquid from flowing out when not in use.

Conventional cleaning equipment that foams detergent and applies the foam to the carpet surface for brushing drips detergent during the cleaning process, and if the detergent solution is not stopped dripping when the detergent is stopped, the carpet may become more wet than necessary or the detergent may become wet. There was a problem that the liquid was wasted, and the operation was cumbersome and difficult.

Additionally, upright cleaning equipment, which is relatively small, compact, and easy to use, is difficult to self-stand, so it is often placed on a carpeted surface when not in use. However, if the device is tipped over, the detergent in the detergent tank may leak out of the device, making the carpet more wet than necessary, and the problem is that the device must be placed upright.

The present invention solves the above-mentioned conventional drawbacks by making it possible to close the air circuit of the fan motor only when it is actually in use, thereby eliminating the troublesomeness of the user during cleaning operations, and eliminating the need for electricity. and detergent liquid,
Furthermore, the present invention provides a device that prevents unfoamed detergent from flowing out even when the device is laid down on a carpet surface.Examples thereof will be described in detail below based on the accompanying drawings.

In the figure, the cleaning device includes a main body 3 with a handle 1 protruding upward and a built-in fan motor 2;
It consists of a cleaning tank 6 equipped with a floor brush nozzle 4 below. More specifically, the detergent tank 5 is rotatably connected to the device main body 3 via a hinge 6 and a buckle 7.

Further, the main body 3 of the apparatus is provided with an exhaust chamber 1o which is communicated with an air inlet 9 of the detergent tank 6 via an annular backing 8. Reference numeral 11 indicates the detergent liquid in the detergent tank 6. 12 is an air discharge pipe whose upper end is connected to the air inlet 9 and whose lower end opening faces the lower part of the detergent tank crystal; 13 is a foam feeding vibrator installed vertically in the detergent tank 6; The floor brush nozzle 4 is connected to it. 14 is a detergent solution supply port formed on the top wall of the detergent tank 5;
Reference numeral 6 denotes a lid which can be opened and closed when the detergent tank 6 is rotated in a bent manner with respect to the main body 3 of the apparatus via a hinge 6.

Now, 16 is an opening/closing rod passing through the center of the foam feeding pipe 13, the tip of which passes through the floor brush nozzle 4 and protrudes downward, and the upper end opens/closes the upper opening of the foam feeding pipe 13. The valve body 17 is fixed. 18 is the opening/closing rod 16
19 is a magnet provided on the valve body 17, and 20 is a reed switch that is opened and closed by this magnet 19. Connected in series to an electrical circuit. 21 is a power switch, and 22 is a check valve.

In the above configuration, when the floor brush nozzle 4 is now grounded on the carpet surface, the opening/closing rod 16 rises due to the weight of the device, and the valve body 17 opens. At the same time, the reed switch 2o is closed by the approach of the magnet 19 provided on the valve body 17, and the fan motor 2 is brought into a fully driven state. The air sent out from the fan motor 2 flows through the exhaust chamber 1o, the annular backing 8, the air inlet 9, and the air discharge pipe 12, and is discharged into the detergent liquid in the detergent tank 5. Therefore, the detergent solution is disturbed by the air rising in the detergent solution, and bubbles are generated in the upper gas phase portion of the detergent tank 6.

The detergent foam is then carried by the air from the fan motor 2 and reaches the floor brush nozzle 4 through the foam supply pipe 13, from which the carpet can be washed.

Next, when the device is lifted to be moved, the opening/closing rod 16 moves downward under the action of the spring 18. However, when the valve body 17 closes and the magnet 19 provided on the valve body 17 separates, the reed switch 2o becomes open. Therefore, unnecessary outflow of detergent and operation of the fan motor 2 can be prevented, and since the operation is automatic, there is no need for any trouble in terms of operation.

Also, if the device is laid down on the carpet during work interruption, the valve body 17 is closed in the same manner as described above, and the operation of the fan motor 2 is stopped.

By the way, the noteworthy point in terms of the above operation is fan motor 2.
The start/stop control of the valve body has just been performed in conjunction with the first valve. That is, in the cleaning device configured as described above, the opening and closing of the valve body 17 and the starting and stopping of the fan motor 2 must be completely synchronized. Furthermore, for example, if the fan motor 2 continues to operate even though the valve body 1 is closed, an overload will be applied to the fan motor 2, and in the opposite case, the detergent foam will not be fed. becomes.

However, in the above embodiment, the valve body 17 and the fan motor 2 are directly linked by the magnet 19 provided on the valve body 17 and the reed switch 20, so that the fan motor 2 can be operated accurately and detergent foam can be prevented. Accurate feeding control is possible.

In the above embodiment, a magnet and a reed switch are used as a linking means between the valve body and the fan motor, but it is also possible to use a mechanism in which the actuator of the switch is mechanically actuated by the movement of the valve body.

In this way, the present invention detects the condition of the floor brush nozzle, opens and closes the foam supply pipe with the valve body, and at the same time opens and closes the switch for controlling the start and stop of the fan motor with this valve body, making cleaning work easier. This prevents wasted detergent solution by eliminating unnecessary detergent spills when lifting and moving the device inside the machine.In addition, the fan motor automatically stops, eliminating the need for troublesome ON/OFF switch operations. Not only is this unnecessary, but power is also consumed only during cleaning, making it possible to save energy. Furthermore, even if the device is placed upside down, it is possible to completely prevent detergent liquid from leaking out of the device.

In addition, by linking the opening and closing of the valve body with the start and stop of the fan motor, the accuracy of the above operation is improved and an excellent cleaning device can be provided.
