Improvement of the jetting device for the one-way high-pressure water in an automatic washing machine to which the above dishwasher is applied is also being studied. There is a method in which a high-pressure water cleaning nozzle is rotated around the object to be cleaned to spray high-pressure water onto the object to be cleaned from multiple directions. The method of spraying on the object to be cleaned from the above-mentioned multiple directions is large in size and expensive, is disadvantageous in terms of space saving and cost saving, and is effective when a large amount of cleaning work of the protective mask is collectively processed. However, there is a problem that it is disadvantageous when the amount of cleaning work is small. Also, there was a problem that many people were reluctant to be washed with other people's masks. The present invention has been made in order to solve the problems of the conventional automatic cleaning device for a protective mask, and an object thereof is a space-saving, inexpensive, cleaning, disinfecting and deodorizing protective masks one by one. It is to provide an automatic cleaner.

As shown in FIG. 3, the automatic cleaning device includes a cleaning tank V, and an impeller 10 rotatably supported by a support shaft provided at the bottom of the cleaning tank V and supported by the impeller 10. A work rotation table 9 is provided. On the upper surface of the work rotation table 9, small columns are arranged so that the mask M can be easily placed.

Further, a water supply pipe 6 is provided at the bottom of the cleaning tank V, and the water supply pipe 6 is bent in a U-shape from above the bottom, and the inside of the bent U-shaped water supply pipe 6 is extended. Is provided with a fixed cleaning nozzle 7. The work rotary table 9 is arranged so as to be surrounded by the U-shaped water supply pipe 6.

Further, the water supply pipe 6 is provided with the cleaning tank V.
A heater 11 for heating the water in the water supply pipe 6 to a high temperature so that it can be used as cleaning water in the vicinity of the bottom of the water supply pipe, and a filter 13 for recovered water for recovering after the cleaning water is used.
Are provided. A pressure pump 12 is arranged at a predetermined position outside the cleaning tank V so as to pressurize the cleaning water in the water supply pipe 6. In addition, in the present embodiment, as the cleaning water, the recovered water recovered through the recovered water filter 13 is used.

Next, the operation of the automatic cleaner will be described. The washing water heated to a high temperature and pressure by the heater 11 and the pressurizing pump 12 was placed on a small column on the work rotary table 9 as the object to be washed from the plurality of fixed washing nozzles 7 through the water supply pipe 6. The mask M is sprayed. Further, since the work rotary table nozzle 8 is directly connected to the lower portion of the work rotary table 9 and is arranged at a position where the cleaning water is sprayed to the integrally provided impeller 10, the spray nozzle is sprayed. Rotational force is generated in the impeller 10 by the cleaning water. This rotational force becomes the rotational driving force of the work rotary table 9.

With such a mechanism, the work rotary table 9 on which the mask M is placed is rotated, and the mask M is rotated.
Not only for the main body 1 but also for the intake port 2 and the exhaust port 3,
Since high-temperature, high-pressure cleaning water is sprayed evenly on the surface, even complex shapes can be cleaned sufficiently. Further, according to the present embodiment, since the rotational driving force is generated by itself, for example, the motor and the like are omitted, so that it is possible to provide a compact device and an inexpensive device. Further, in the present embodiment, the water supply pipe 6 having a U-shaped bent shape is used, but it may have an arc shape or an elliptic curve shape.

[Embodiment 2] An automatic cleaning device according to another embodiment of the present invention will be described with reference to FIG. In FIG. 2, the same symbols as in FIG. 1 are the same parts in FIG. Only new symbols will be described. In FIG.

The automatic cleaning device shown in FIG.
It has a simple structure except for the pressurizing pump 12 and the heater 11 for heating the washing water to a high temperature in the automatic washing device. Further, the structures of the fixed cleaning nozzle 7, the work rotary table nozzle 8, the work rotary table 9, and the impeller 10 and their positional relationships are the same as those in [Example 1], which is troublesome. Therefore, the description is omitted.

In FIG. 2, the hot water tank 14 is filled with hot water from a water heater 18 (not shown) to a certain level through the solenoid valve 17. The water level is controlled by the water level detector 16 by opening and closing the solenoid valve 17. The L-shaped water supply pipe 6 ′ is connected to the bottom of the hot water tank 14. Therefore, the hot water tank 14 is provided in the L-shaped water supply pipe 6 '.

A compressed air supply pipe 15 having an opening at a position slightly lower than the water level is built in the L-shaped water supply pipe 6 ′, and the compressed air supply pipe 15 is connected to a compressed air source (not shown). .

In the above structure, when compressed air is supplied to the compressed air supply pipe 15, a siphon action is exerted in the L-shaped water supply pipe 6'to mix the compressed air with the hot water. The cleaning water is supplied to the fixed nozzle 7 and the work rotary table nozzle 8 as cleaning water.

The cleaning water is sprayed not only from the fixed nozzle 7 to the mask body 1 but also to the intake port 2 and the exhaust port 3, and at the same time, is sprayed from the work rotary table nozzle 8 to the impeller 10. Can be attached. The collision energy required for cleaning and the rotational force for rotating the work rotary table 9 are given by the compressed air, and can be effectively cleaned with a small amount of cleaning water.

According to the above-described embodiment, the mask M has a complicated shape because the cleaning water is uniformly sprayed not only to the mask body 1 but also to the intake port 2 and the exhaust port 3 by such a mechanism. Also, sufficient cleaning is possible. Further, according to this embodiment, since the rotational driving force is generated by itself, for example, a motor or the like can be omitted, so that the device can be downsized and an inexpensive device can be provided. Also in this embodiment, the shape is not limited to the L-shaped water supply pipe, and may be an arc shape or an elliptic curve shape.

The present invention is not limited to the above embodiments, and the cleaning water may be a circulating system using recovered water or a disposable non-circulating system. Further, the heater 11 may be used in the cleaning tank V to install a drying system. The object to be cleaned is not limited to the mask, and may have a complicated other shape.
It does not matter as long as it can rotate.

[0025]

As described in detail above, according to the present invention, it is possible to provide a space-saving inexpensive automatic cleaning device for cleaning, disinfecting and deodorizing protective masks one by one.
More specifically, according to the configuration of the present invention, high-pressure cleaning water is sprayed onto the object to be cleaned from fixed cleaning nozzles mounted on the upper and side surfaces, and is integrated with the rotary table on which the object to be cleaned is placed. By rotating the impeller, even an object having a complicated shape can be uniformly cleaned, disinfected and deodorized. Therefore, the automatic cleaner does not need to use a drive source for rotation, such as a motor,
It is possible to provide a compact and inexpensive automatic cleaner.

According to another structure of the present invention, high temperature,
High-pressure washing water, for example, is sent from the water heater to the water supply pipe so that the water level is constant, and a compressed air supply pipe having an opening is built in at a position slightly lower than this water level. The cleaning water and the compressed air are mixed and urged in the water supply pipe so as to be ejected from the fixed cleaning nozzle, thereby giving a rotating force to the impeller and a cleaning force to the object to be cleaned. Therefore, the automatic washing machine does not require a drive source, a pressurizing pump, a heater for heating, or the like, and it is possible to provide a smaller and cheaper automatic washing machine.
