Abstract

PURPOSE:To clean the interior of tyre house reliably which is difficult through manual work by detecting through tyre detector that a car is at the correct cleaning position and cleaning the tyre house on the basis of said detection. CONSTITUTION:Upon advance of car 8 between movable rails 7, 7 of car washer gate 6, the front wheel tyre 9 of car will step over a tyre detector 1. Consequently, an output signal is produced from said detector 1 to open a valve 5 thus to inject cleaning liquid from cleaning nozzles 2a-2d through feed tube 4 and to clean the tyre and tyre house automatically.

Description

[Detailed description of the invention] [Technical field to which the invention pertains] The present invention relates to a cleaning device for a tire house of an automobile.

[Prior art and its problems]

The so-called tire house area on the underside of the body that covers the tires of the 9-wheeled car is particularly susceptible to dirt due to mud splashes and the like.

By the way, for example, at gasoline filling stations for automobiles, various car wash machines are installed to wash cars, but conventional car wash machines only spray washing water from above and from the sides, so it is difficult to wash even the tire house part. There was a drawback that the water did not spread and dirt remained in the area.

Therefore, if the car is washed manually using a car wash bowl or the like, it is possible to thoroughly wash the tire housing, but this process is not easy as it requires time and effort and also causes water splashes.

[Purpose of the invention]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a cleaning device which eliminates the above-mentioned disadvantages and can easily and automatically clean the tire house of an automobile when the automobile comes to the proper position for cleaning.

[Key points of the invention]

However, this object is achieved according to the invention by providing adjacently a tire detector and a tire house cleaning nozzle which is controlled by the output of the detector.

(Example of the invention) Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a plan view showing an embodiment of the cleaning device of the present invention, and FIG.
The figure is a front view of the same as above, and 1 in the figure is 11 of tire 9 of car 8.
], for example, a rectangular tire detector with a certain length, and the detector is placed underground with the top surface almost flush with the ground surface so that it can be stepped on the tire. Bury it. It is conceivable that this detector 1 uses a weight detection switch using one code cell.

A cleaning nozzle 2a is installed adjacent to and around the tire detector 1.
, 2b, 2c, and 2d were arranged upward so that the openings were located almost on the same plane as the ground surface, similar to the rijji detector 1. Further, a supply @ 4 of cleaning water or detergent is connected to each of the cleaning nozzles 2 a to 2 d, and a valve 5 that opens and closes in response to a detection signal from the tire detector 1 is provided in the middle of the supply pipe 4 . In addition,
In place of the valve 5, a pump may be provided that is directly driven and controlled by the detection signal.

As shown in FIG. 3, such a cleaning device is installed at a point where automobile tires pass, on the inner side of a moving rail 7.7 of a recessed car washer 6 installed at a gasoline filling station.

Note that the washing device may be installed alone in addition to being installed in combination with a car wash as described above.

Next, to explain the usage and operation, in order to wash the car 8, if the car 8 enters between the moving rails 7 and 7 of the concave car wash machine 6, the front tires 9 of the car 8 will first be detected by the tire detector 1. Step on the front edge of the

The tire detector 1 produces an output, and the output signal causes the valve 5 to
opens, and the washing water or detergent starts to be jetted upward from the washing nozzles 2a to 2d via the supply pipe 4,
First, mainly the rear portions of the tire 9 and the tire/'% spacer 10 are washed with water jetted from the front nozzle 2C. The cleaning water continues to be ejected while the tire 9 is stepping on the tire detector 1, and as the tire 9 passes over the tire detector 1, the washing water is ejected from the nozzles 2b and 2d on both sides of the detector 1. The middle part of the tire 9 and the tire house 10 is mainly cleaned, and then when the tire 9 approaches the rear end of the detector 1, the cleaning water from the rear nozzle 2a washes the tire 9 and the tire house 10. When it hits the house 10, the front part is mainly cleaned (
Figure 2 (dotted line position).

When the car 8 further advances and the tire 9 comes off the tire detector 1, the detector 1 no longer produces any output, so the valve 5 closes and the supply of cleaning water to the nozzles 2a to 2d is stopped. The gushing stops.

If the car 8 moves further, the rear tires 9 will be tied.
1. Inspection 1] Step on device 1 to clean the rear wheels as well as the front wheels.

In this way, while the tire 9 is stepping on and passing over the tire detector 1, cleaning water continues to be spouted from the nozzles 2a to 2d.
Tire 9 and tire nous 10 are cleaned,
If the entire body of the car 8 is subsequently washed with the concave washing machine 6, the car B will be completely washed by 6L.

Note that the cleaning of the tire house 10 may be performed after the body car washing is completed.

〔Effect of the invention〕

As mentioned above, the cleaning device of the present invention is equipped with a cleaning nostle adjacent to the tire detector that is activated by the output from the detector, so that the cleaning device of the present invention is equipped with a cleaning nostle that is activated by the output from the tire detector. Washing water continues to spray out from the nozzle while you step on the car and hits the tire house at the bottom of the car, making it easy to wash those parts that are difficult to reach with an electric car washer and difficult to clean by hand. It is something.

Moreover, since the washing starts automatically when the car comes to the proper position for washing, the washing can be done reliably and it is also useful for saving water resources and the like.
