  A slide device 30 is attached to the lower cover 24 of the cleaning tank 2 and pushes out the cleaning tank 2. As shown in FIG. 3, a slide shaft 33 provided with a rack 34 is provided in a groove 32 provided in the main body 31. It is supported by the holding part 35 and is slidably inserted in the axial direction (front-rear direction). A motor 36 is a driving means for the slide shaft 33 provided in the main body 31, and a pinion 37 that meshes with the rack 34 is provided on its output shaft. Reference numeral 38 (FIG. 4) denotes a backward position detector provided near the innermost portion of the groove 32 and detects the backward position of the slide shaft 33, and 39 is a forward position detector that detects the forward position.

  As shown in FIG. 4A, the slide device 30 configured as described above is configured so that the slide shaft 33 is formed in the groove 32 of the main body 31 when the cleaning tank 2 is accommodated at a predetermined position in the main body 1 of the cleaning machine. It is inserted to the innermost part, and the tip part is in contact with the rear wall of the cleaning machine body 1 (hereinafter, this state of the slide shaft 33 is referred to as retreat). At this time, the reverse position detector 38 detects that the slide shaft 33 is at a predetermined reverse position.

  When the open switch 9 of the operation unit is turned on in this state, the motor 36 is energized to rotate the pinion 37 in the direction of arrow a. As a result, the slide shaft 33 tries to move in the right direction in the drawing (hereinafter referred to as advancing). However, since the tip of the slide shaft 33 is in contact with the rear wall of the washing machine body 1, the pinion 37 With rotation, the main body 31 moves in the direction of the front opening of the cleaning machine main body 1, and the cleaning tank 2 to which the main body 31 is attached moves along the guide rail and is pushed forward from the front opening of the cleaning machine main body 1. . When the entire length of the slide shaft 33 moves forward, it is detected by the advance position detector 39, and the motor 36 is stopped. If the motor 36 is rotated in the opposite direction, the slide shaft 33 moves backward to a predetermined position, and the backward position detector 38 detects this and stops the motor 36.

  A control unit 50 is disposed between the cleaning tank 2 and the door 4 and connected to the operation unit 6. The control unit 50 includes a microcomputer. The microcomputer includes the operation unit 6, a water amount detection unit, and the temperature of the cleaning water.

Thereafter, rinsing of the tableware 22 and the like is performed by the same operation as the above-described cleaning process, and drained when the rinsing is completed for a predetermined time. Such rinsing and draining are repeated a plurality of times (rinsing step).

When the predetermined number of rinsing steps are completed, the blower 18 and the second heater 20 are energized to introduce outside air into the cleaning tank 2. The outside air is heated by the second heater 20 to become warm air, sent to the cleaning tank 2 to dry the entire area of the tableware 22 and the cleaning tank 2, and the hot air that has dried them is discharged from the exhaust port 10 to the outside. Is discharged (drying process).
When the predetermined time elapses, the energization to the blower 18 and the second heater 20 is stopped, and the drying process ends. Thereby, washing | cleaning, rinsing, and drying of the tableware 22 are completed. The series of operations are automatically performed according to a program set in the microcomputer 41 of the control unit 50. Even during operation of the dishwasher, the slide device 30 can be driven to push out the washing tank 2 by turning on the start / pause switch 8.

  When taking out tableware 22 etc., the open switch 8 of the operation part 6 is turned ON, the washing tank 2 is pushed forward from the front opening part of the washing machine main body 1 by the slide device 30, and the tableware basket 21 or tableware 22 is taken out. The washing tank 2 is returned to the washing machine main body 1 again. The operation of the slide device 30 at this time is as described above.

  According to the present embodiment, when the tableware 22 or the like is washed or when the tableware or the like 22 after the washing is taken out, the heavy washing tub 2 storing the table 22 is moved by the slide device 30 to the front opening of the washing machine body 1.
