DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a small dishwasher according to an embodiment of the present invention. In this figure, reference numeral 1 is a frame, and a cleaning chamber 3 in which a rack 2 is installed is formed in the upper part of the frame 1. The rack 2 carries dishes D and is rotated by a rotating shaft 5 which is rotated by a motor 4 in the direction of arrow U. A cleaning pipe 6 has a plurality of cleaning nozzles (not shown) for spraying hot water at its tip. 7 is a cleaning tank, which is a frame 1
Detergent is supplied from a tank (not shown) installed inside. The cleaning tank 7 is arranged at the bottom of the rack 2 so that the hot water sprayed from the cleaning nozzle can be collected. A rinsing hot water tank 8 stores the rinsing hot water supplied from the outside via the hot water supply pipe 9. Reference numeral 10 denotes a pump, which sucks up the cleaning liquid or the rinse water from the cleaning tank 7 or the rinse water tank 8 and supplies it to the cleaning pipe 6.
Reference numeral 11 is a three-way valve, which is used for cleaning from the cleaning tank 7 to the pump 1
The valve is opened toward 0, and at the time of rinsing, it is opened from the rinsing bath 8 toward the pump 10. The switching of the three-way valve 11 is automatically performed when the cleaning process ends and the process moves to the rinsing process.

Further, reference numeral 12 is a drain tank, and the opening / closing valve 13 is opened at the end of the cleaning process so that the cleaning liquid after the cleaning process is drained through the drain pipe 14. 1
Reference numeral 5 denotes a residue filter which collects the residue contained in the cleaning liquid and the rinse water. Reference numeral 16 denotes a drain port, which drains the cleaning liquid drained to the drain tank 12 to the outside.

Next, the operation of the small dishwasher according to this embodiment will be described. First, when the tableware D is stored in the rack 2 and a start switch (not shown) is operated, the motor 4
