The open position of the door (2) is determined because the door (2) comes into contact with the back side of the door (2).

Next, detergent is poured into the washing tank (18) and the container (12) containing one tableware is inserted into the box (1) through the opening (1a).
Insert it into the box, place it on the rail (13), and store it inside the box (1). Now, when door (2) is closed, each part operates in the reverse order as described above, door (2) is locked, and door switch (
9) operates as shown in FIG. 6(a), and one circuit becomes operable. Note that the shutter (61) is connected to the exhaust port (5
8) is closed and detected by the shirt closure detection switch (69B).

Here, when a fully automatic switch (not shown) on the operation panel (70) is operated, a cleaning operation is started as follows in response to a command from the control device (71).

■The prewash switching valve (39) operates, and the pipe (41) and pipe (42)
), and the tap water passes through the pipe (42) to the water supply pipe (
36) and is injected downward from the water supply nozzle (36a).

The dishes in the basket (12) are pre-washed and then fall and are stored in the washing tank (18). This action is 10-3
Lasts for 0 seconds.

■The water heater (20) is energized to heat the water stored in the cleaning tank (18) to approximately 50°C (details omitted), and the switching valve (39) is switched (at this time, the switching valve (45) connects the pipes (46 and 47)).

When the pipes (41), (43), (46), and (47) are connected, tap water flows through the rinsing pump (26) to the water storage machine (2).
4), and when the water supply is completed, the switching valve (39) is turned off. Then, the heater (25) is energized to heat the supplied water to about 80° C. (details are omitted).

During this time, the water applied to the dishes during the pre-washing softens the cooked rice and the like that adhere to the dishes, making them easier to remove.

The hot water storage device (24) can be adjusted to any desired temperature using a hot water temperature adjustment device (not shown), so that hot water at a washing and rinsing temperature suitable for dishes, pots, etc. can be obtained.

The zero washing pump (21) is driven, and the hot water containing the detergent stored in the washing tank (18) is supplied from the pipe (53) to the washing pipes (32) (33), and the washing nozzle (32a)
) (33a) The water is sprayed onto the tableware in the container (12) to wash it. At the same time, the motor (14) is driven to rotate the eccentric cam (15). Now, Figure 7 (a)
), the heel (12) moves to the door (2) side and compresses the push spring (16), and the push spring (16) moves as shown in Figure 7(b).
), the cage (12) moves toward the eccentric cam (15). Since the heel (12) swings in the horizontal direction in this manner, the hot water jetted from the cleaning nozzles (32a) (33a) evenly washes the tableware in the heel (12).

The hot water after washing falls into the washing tank (18), is again supplied to the washing pipes (32) and (33) by the washing pump (2 parts), and this process is repeated thereafter.

When the cleaning is completed, the switching valve (22) is turned off and the hot water in the cleaning tank (18) is discharged to the sewer through the drain pipe (23).

■The rinse and wash selector valves (39) and (45) are switched and the pipe (4
1) (43) (46) (51) are connected, the tap water flows through the pipe (51) (4) via the rinse pump (26).
g) to the rinsing pipes (34) and (35), and is sprayed from the rinsing nozzles (34a) (35a) onto the tableware in the heel (12). The tap water is also supplied to the water sprinkling pipe (37), and is sprayed from the water nozzle (37a), and the water sprinkling pipe (3) rotates in a horizontal plane due to the reaction force. In this way, the detergent adhering to the tableware is washed away by the water jetted from the rinse nozzles (34a) (35a) and the water spray nozzle (37a). During this time, the basket (12) is rocked in the same manner as during main washing.

Next, the switching valve (45) operates again, and the piping (46) (
47) is connected. Here, when the rinsing pump (26) is operated, the hot water in the hot water storage device (24) is fed under pressure to the rinsing pipes (34) (35) and the water sprinkling pipe (37), as in the case of the water rinsing described above. Supplied. Also, rinse pump (
29) is operated to suck a certain amount of rinse in the rinse pump (28) and mix it into the hot water in the pipe (48). In this way, one piece of tableware is thoroughly rinsed and the finished product is good. Note that the cage (12) is swung in the same manner as in the case of water rinsing.

■The water drain switching valve (31) is switched and the air pump (30)
When the is operated, compressed air is supplied to the rinse pipes (34), (35) and the water spray pipe (37) through the pipes (50) and (48), and from the rinse nozzles (34a) (35a) and the water spray nozzle (37a). Injected. Moisture remaining on the tableware is blown away by this jet of air. In this way, it is possible to sufficiently blow away the rinsing water remaining in the recesses of one tableware, especially in the deep threaded bottoms peculiar to Japanese tableware. Also,
The basket (12) is rocked in the same manner as in the case of rinsing. In addition, the noise during washing so far does not go out from the exhaust port (58) due to the closure of the shutter (61), and the scattering of washing water outside the box (1) is also prevented by the shutter (61). 61) and a shielding plate (57).

■When the steam vent motor (62) is driven, the pulley (63) rotates and the string (64) is wound up, the shutter (61) moves and the exhaust port (58) is opened, and the shutter is opened. Detected by the switch (69A), the motor (62) is stopped. Here, when the blower (59) is operated, the air outside the box (1) is sucked in through the air supply port (54), passes through the dust removal filters (55) and (56), becomes clean, and the air outside the box is drawn in. (1) to form an air flow that passes through the air outlet (58) and is discharged from the exhaust port (58). At this time, steam is generated inside the box (1) due to evaporation of residual moisture, and this steam is discharged from the exhaust port (58) by the air flow, thereby promoting the drying of the tableware.

■Completion When the steam release operation described above has been carried out for a predetermined time, the blower (59
) stops and the motor (62) rotates in the opposite direction.

Now, the string (66) is pulled by the force of the tension spring (67),
The shutter (61) moves and the exhaust port (58) is closed, which is detected by the shutter closure detection switch (69B) and the motor (62) is stopped.

Note that the cleaning hot water stored in the cleaning tank (18) is as follows.
