Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic cleaning device,
For example, the present invention relates to an automatic cleaning device suitable for removing dust from a protective mask, removing oil, disinfecting mouth odor and bacteria in the mouth, and automating a drying operation.

[0002]

2. Description of the Related Art In terms of its function, a protective mask has a complicated structure for adhering to the face and also has projections such as an absorption can and an exhaust port, and dust that has infiltrated into this part cannot be easily removed. . On the other hand, the oral odor and bacteria in the mouth of the person who uses it are attached, and these problems are left unsolved by the currently practiced means for blowing off with alcohol or disinfectant.

As a solution to these problems, as in the parts cleaning device disclosed in Japanese Utility Model Publication No. 55-9429, the object to be cleaned is set in a rotary basket and high-pressure water is synchronized with the rotation of the rotary basket. A method in which the cleaning nozzle is vertically rotated around a rotating basket and high-pressure water is sprayed on the object to be cleaned is effective, but there are the following points to be improved.

[0004]

That is, when the high-pressure water is sprayed for cleaning, there is a problem that it takes time to dry after cleaning. This can be said to be the same as in the case where the cleaning product is dried by the heat of the heater, because the drying time is naturally limited.

The present invention has been made in view of the above points, and an object thereof is to perform effective cleaning, disinfection, and deodorization even for an object to be cleaned having a complicated shape such as a protective mask as described above. An object of the present invention is to provide an automatic cleaning device that can obtain the work time and shorten the work time until the cleaning and drying.

[0006]

In order to achieve the above-mentioned object, the present invention connects a high pressure water supply pipe and a compressed air supply pipe to a cleaning nozzle so that they can be switched by sharing a part of the pipe, and Means for heating the washing water leading to the high pressure water supply pipe to a high temperature,
Means for converting cleaning water into high-pressure water, and high-pressure, high-temperature cleaning water is sprayed on the object to be cleaned through the high-pressure water supply pipe and the cleaning nozzle for a set time, and then the high-pressure water supply pipe is automatically shut off to supply the compressed air. And a cleaning control system with a timer for blowing compressed air from the cleaning nozzle onto the object to be cleaned for a set time by opening the pipe.

[0007]

With the above construction, high-pressure, high-temperature water is sprayed onto the object to be cleaned through the cleaning nozzle to effectively remove dust and oil adhering to the object to be cleaned, and to disinfect and deodorize. It After the cleaning work is completed, the high pressure water supply pipe is automatically shut off by a timer, the compressed air supply pipe is opened, and compressed air is blown to the object to be cleaned through the compressed air supply pipe and the cleaning nozzle. As a result, the water droplets adhering to the object to be cleaned are blown off and draining work is performed. As a result, the automation from the cleaning to the drying is achieved and the drying of the object to be cleaned in the drying step is promoted.

In the above drying step, the surface of the object to be cleaned is deprived of heat by blowing compressed air. Therefore, by supplying the heat energy for compensating for this heat loss by using the hot air generator, it is possible to further increase the heat energy. The drying time can be shortened.

And a cleaning nozzle 6 is provided. The rotary cage 5 and the cleaning nozzle 6 share the same motor 14 and rotate synchronously, and the cleaning nozzle 6 is set to rotate vertically around the rotary cage 5 to uniformly clean the protective mask as the object to be cleaned 1. It is a system that can. This mechanism itself is known from Japanese Utility Model Publication No. 55-9429, and in this embodiment, the following mechanism is further provided.

The high-pressure water supply pipe 13 and the compressed air supply pipe 16 share a part of the pipes and are connected to the same cleaning nozzle 6, and the supply pipes 13 and 16 have switching valves (solenoid valves). ) 17, 18 are provided. The high pressure water supply pipe 13 is provided with a pump 11 driven by a motor 12.
The hot air blowing section of the hot air device 19 is introduced into the cleaning tank 4.

Inside the washing water tank 7, there are built-in a heater 8 for heating the washing water to a high temperature, a screen 9 for collected water, and a screen 10 for water supply. Each screen is composed of a filter and a wire mesh. Employs methods such as incineration or cleaning and reuse. High pressure water supply pipe 13
