Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an improvement in an automatic cleaning device having a cleaning head that moves for cleaning.

First, a conventional automatic cleaning device will be explained with reference to FIG.

In the figure, 1 is the cleaning surface, 2 is the cleaning head, 3 is the frame, 4 is the squeegee attached to the frame 3,
5 is a brush attached to the frame 3, 6 is a nozzle fixed to the frame 3, 7 is a detergent liquid discharged from the nozzle 6, 7' is a stored detergent liquid, 8 is a tank, 9 is a pipe 10, 11 12 is a pipe connecting the cleaning head 2 and the tank 8, and 13 is a vacuum device communicating with the tank 8 through a pipe 14.

That is, while the cleaning head 2 is moving in the cleaning movement direction, that is, in the direction of arrow A, the detergent liquid 7' stored in the tank 8 is pressurized by the pump 9 and discharged from the nozzle 6 onto the cleaning surface 1, thereby moistening the cleaning surface 1. A brush 5 is used to scrub dirt (not shown) adhering to the cleaning surface 1, and a squeegee 4 is used to wipe off the dirt and detergent liquid 7, which is collected into a tank 8 through a pipe 12. At this time, in order to improve the recovery efficiency of the detergent liquid 7 and the cleaning finish, the inside of the tank 8 is brought to negative pressure by the vacuum device 13. Note that detergent liquid 7 is used to improve the cleaning effect. However, the detergent liquid 7 cannot be sufficiently wiped away with the squeegee 4, and the detergent liquid 7 remains on the cleaning surface 1 after cleaning.
This residual detergent solution 7 may discolor the surface of the cleaning surface 1, such as aluminum or glass, and therefore, as a result of using a diluted detergent solution as the detergent solution 7, a sufficient cleaning effect may not be obtained.

This invention aims to solve the above-mentioned drawbacks and to provide an automatic cleaning device that does not generate residual detergent liquid.

An embodiment of this invention will be described below with reference to FIG.

In the figure, the same symbols as in Figure 1 indicate the same parts, and 15
15' is the discharged washing water, 15' is the stored washing water, 16 is a tank in which the detergent solution 7' and the washing water 15' are separated and communicated at the upper part, and 17 is the detergent solution 7' in the tank 16 and the pump 9. A solenoid valve located in the middle and communicated by pipes 10 and 18, 19 is a wash water 15' of the tank 16.
22 and 23 are solenoid valves that are in communication with the frame 3 and the pipe 24, and 25 is a solenoid valve that is in communication with the detergent liquid 7' side of the tank 16. 26 is a pipe communicating with the solenoid valve 23 and the cleaning water 15' of the tank 16;
27 is a switching device consisting of electromagnetic valves 17, 19, 22, and 23; 28 is a switching device that mainly contains cleaning water 15';
A washing water device 29 is composed of pipes 18, 25 and the like, and a detergent liquid device 29 mainly contains a detergent liquid 7'.

That is, the first cleaning is performed using the detergent liquid 7'. At this time, while the cleaning head 2 is moving in the direction of arrow A, the solenoid valve 17 is opened and the pump 9 is rotated to discharge the detergent liquid 7 from the nozzle 6 onto the cleaning surface 1, thereby moistening the cleaning surface 1 and brushing. 5, the dirt (not shown) adhering to the cleaning surface 1 is rubbed off, and the squeegee 4 is used to wipe off the dirt and detergent liquid 7. At the same time, by operating the vacuum device 13 and opening the solenoid valve 22, the dirt inside the frame 3 and the detergent liquid 7 are collected into the detergent liquid 7' side of the tank 16 and reused. A second cleaning is then carried out, this time using cleaning water 15'. At this time, the solenoid valves 19 and 23 are opened and the pump 9 and the vacuum device 13 are operated to discharge the cleaning water 15 from the nozzle 6 onto the cleaning surface 1, and the squeegee 4 is used to discharge the cleaning water 15 containing the residual detergent liquid 7. is collected into the wash water 15' side of tank 8 and reused. Therefore, first remove the dirt sufficiently with the detergent solution 7, and then remove the remaining detergent solution 7 with the washing water 15.
can be recovered. Therefore, detergent liquid 7
It is possible to prevent problems that may occur on the cleaning surface 1 due to the remaining particles. Further, it is possible to use the washing liquid 7 with an appropriate concentration, and a good cleaning effect can be obtained. In addition, the tube 14 of the vacuum device 13 is connected to the tank 1.
By providing the washing water 1 on the detergent solution 7' side of No. 6,
5 can be prevented from becoming dirty due to scattering of the detergent liquid 7.

In this embodiment, the tank 8, the vacuum device 1
3. One pump 9 and one nozzle 6 were used, and the switch was configured to be switched by a switching device 27, but the nozzle 6, pump 9, tank 8, and vacuum device 13
It is clear that the same effect can be obtained even if two are provided, one for detergent liquid 7' and one for wash water 15', and these are switched by a switching device.

As explained above, this invention is equipped with a detergent liquid device and a washing water device, and uses a switching device to first clean with the detergent liquid and then with the washing water, so that there is no possibility that the detergent liquid remains on the cleaning surface. The purpose of the present invention is to realize an automatic cleaning device that prevents troubles caused by cleaning and provides a good cleaning effect.
