Next, the usage and operation of the present invention will be explained. First, open the door 6, take out the dishwashing basket 5 from the washing chamber 1a onto the door 6, put the dishes D into the dishwashing basket, and insert this dishwashing basket into the washing chamber 1a. . At this time, there are rails 3a and 6a on the rotating table and door, and a slider 5a on the dishwashing basket, so that the sliding is performed very smoothly and at the same time, the centers of the dishwashing basket 5 and the rotating table 3 are in the same position. The adhesive steel piece 5b provided at one end of the slider 5a and the magnet 3b provided at one end of the rail 3a come into contact, and the dishwashing basket 5
The lock stops. When the start switch is turned on after closing the door 6, the reversible drive motor 2 rotates, and the rotary table 3 and dishwashing basket 5 are rotated alternately in forward and reverse directions at low speed. At the same time, the solenoid valves 21 and 17 open, the pump 9 starts, and the cleaning water in the tank 15 in the cleaning chamber is injected into the injection pipe 8.
The washing water J is supplied to the tableware D all at once from the nozzle 8a. The jet water J is supplied from above and below and from the sides of the rotating tableware D while changing its direction,
In addition, since the water temperature, water pressure, amount of detergent, etc. are appropriately controlled, dishes can be washed efficiently. The cleaning water passes through the pipe 13 from the cleaning chamber 1a, returns to the tank 15 via the solenoid valve 17, and is sent to the pipe 8 by the pump 9 again. When the cleaning process is completed, the solenoid valve 21 is closed to stop the pump 9, the supply of cleaning water is stopped, and water is drained from the drain pipe of the tank 15.

After that, the solenoid valve 22 of the pipe 20 is opened, the pump 9 is started, and rinsing water or hot water is supplied from the rinsing water tank 16 to the water injection pipe 8, and rinsing water is injected onto the dishes in the same way as during the washing process. Clean the dishes by rinsing off dirt and detergent left on them. The used rinsing water or hot water is collected from the strainer 11 into the wash water tank 15 via the solenoid valve 17 with the valve 18 closed, and is used as the second wash water. When not in use, drain water from the drain pipe of the tank 15. In addition, the solenoid valve 18
Open the solenoid valve 17, close the solenoid valve 17, circulate the rinsing water, and use it again, then close the solenoid valve 18.
Close the tank 15 and open the solenoid valve 17.
The rinse water may be recovered. When the rinsing process is completed, the solenoid valve 22 is closed, and at the same time, the pump 9 is also stopped to stop the supply of rinsing water. The temperature of the rinsing water is controlled by a heater 23. After the rinsing process, only the dishwashing basket 5 is rotated, the rinsing water is shaken off, and the dishes D are preheated and dried.

If necessary, the heater 10 is then energized to dry the tableware. The drying time and temperature of the heater 10 may be set in advance.

To take out tableware D from the washing chamber 1a, open the door 6.
Tilt it outward and hold it horizontally, position the rail 3a on the rotating table 3 and the rail 6a of the door 6 in a straight line, and slide the slider 5 provided on the dishwashing basket 5.
It can be smoothly pulled out onto the door 6 by a.

Alternatively, the washing chamber 1a may be used as a tableware storage without removing the tableware D from the washing chamber 1a. Note that the conversion of the speed and rotation direction of the rotary table and the speed of the water jetted by the nozzle 8a are determined by changing the rotation speed of the pump, the rotation speed of the rotary table 3, and the conversion time of the rotation direction depending on the shape, nature, and degree of dirt of the tableware. By changing the conditions, cleaning can be performed under optimal conditions. Further, the temperature of the washing water and the rinsing water and the concentration of the detergent are adjusted as appropriate depending on the degree of soiling of the dishes and the properties of the dishes.

(Effects of the Invention) According to the present invention, jet water can be supplied to the tableware from all directions, and since the position where the tableware is to be washed on the rotary table is changed, the washing water can be applied to the entire surface of the tableware. This makes it possible to completely remove stains from dishes, significantly shorten cleaning time, and save electricity and water. It also allows you to wash high-quality tableware without damaging the tableware.

Since the jet water is supplied to the dishes from all directions, instead of being supplied only from one side below as in the conventional method, the time consuming and troublesome cleaning of the washing chamber after washing can be reduced. Furthermore, by installing rails on the turntable and door and a slider on the dishwasher basket, it becomes easier to put in and take out the dishwashing basket containing dishes. In addition, since the center of the dishwashing basket and the center of the rotating table are fixed in the same state, the center of the dishwashing basket and the center of the rotating table do not shift, and the dishwashing basket and the dishes are not damaged.

Since the rotary table is directly fixed to the drive shaft of the motor, the rotational force from the motor is directly transmitted, and the dishwashing basket can be smoothly rotated.

Since the rotary table is formed in a net shape, it is lightweight and does not interfere with the jetting of water from below, allowing the jetting water to fall smoothly to the bottom of the frame, allowing the dishwashing basket to be removed. You can see through the bottom if you like.
