This problem is solved by forming a dish washer/dryer with the provided heater.

(E) Function The present invention provides a heater for the passage connecting the water tank and the pump body, and uses a blower device to blow air into the passage, so that the passage can be used for circulating cleaning water. The passage body serves as a ventilation passage for sending air from the blower into the dish storage, and the nozzle body spouts cleaning water and hot air.

(c) Embodiment FIG. 1 is a side sectional view showing an embodiment, and FIG. 2 is a sectional view of a main part.

The dish washer/dryer (1) has an inner case (3) with a front opening forming a dish storage (0), an outer case (4) that stores the inner case (3), and an inner case (3) with a front opening. A main body (6) is formed by an opening/closing door (5) that opens and closes. The inner case (3) is formed into a watertight box, and the tableware (8) placed in the tableware basket (7) is stored in the tableware storage (2) formed by the inner case (3). The lower part of the inner case (3) is a water tank (9) for storing washing water, and the tableware f&i (7) is stored above the water tank (9). A tube body αα is protruded from the center of the water tank (9), and a nozzle body αυ is pivotally supported on the tube body α0). The nozzle body Uυ is located between the washing water of water 1 (91) and the dish basket (7).
Cleaning water or hot air sent from the nozzle body αl) to the nozzle body αl) is ejected from the jet port, and the nozzle body αl) is rotated by the force. Inner case (3)
A pump body @ is connected to the more protruding pipe body α0).

The bottom wall portion of the inner case (3), which serves as the water tank (9), has a water intake side covered with a filter body (2). The water intake side and the pump body ■ are connected through a passage body. Passage body
are the pump body ■, the water intake side, the drainage pump αe, and the blower α
η and a connection box side that forms a connection part with the water supply solenoid valve. A connecting sheath part (a heater (support) is provided at the connection part α9 to the pump body (1)). The connection part with the water supply solenoid valve is located above the connection part side. The connection part with the air blower α mark is formed on the upper surface of the ring part, and the air blower a
9 blows air into the ring part (2). Air blower ffi! When air is sent into the ring part (to) by the field, it flows into the storage (2) and is discharged to the outside of the main body (6) through an exhaust port (not shown) formed in the upper part of the inner case (3). Air blower α9
Inhales air from the space between the inner case (3) and outer case (4), and air is supplied to the space between the inner case (3) and outer case (4) from the intake port formed in the outer case (4). be done. The connection part (2) with the water intake port α4 of the water tank (9) is formed on the lower side wall orthogonal to the connection part (2).

Next, the operation will be explained.

When you open the water supply solenoid valve and start water supply, the water inside the sheath αa is supplied, and as the water level rises, the water tank (
Water flows into 9), and a water level detection trowel (not shown) detects the specified water level and closes the water supply solenoid valve. When the water supply is finished, the pump body @ is operated and at the same time, the heater (■) is energized to start the cleaning operation. In the cleaning operation, the nozzle body αD starts ejecting water from the pump body (■) while increasing the temperature of the cleaning water, and the cleaning water that has returned to the water tank (9) returns to the ring part a81 through the water intake port a, and then returns to the nozzle body α1). More erupts. At this time, detergent is dissolved in the washing water. The temperature of the cleaning water is
) is detected and controlled by a temperature sensor (thermistor) placed on the inner wall of the washing water, and after the temperature of the washing water reaches 60 degrees, the washing operation is carried out for one minute and then terminated. When the cleaning operation is finished, the drain pump is turned into an AE system to drain the water, and when the drainage is finished, water is supplied again, and a cleaning operation without adding detergent, that is, a so-called rinsing operation, is performed. When rinsing is completed, the water is drained and then the drying operation begins.

During the drying operation, the blower αη is operated, the heater (2) is energized, and the pump body (2) is operated. The air blower No. 09 increases the internal pressure in the whistle part aB, and when the air is blown into the storage compartment (2) from the water intake port a at that pressure, the same pump unit sends the air to the nozzle body αυ. , the air is blown into the storage compartment (2) from the outlet of the nozzle body αυ. At this time, the nozzle body αυ rotates although it is not in the middle of cleaning, mixing and stirring the air from the water intake side. When the heater ω is energized, hot air flows from the nozzle body αυ, and when it is sent into the ring part, it is heated by the special heater ■, which causes turbulence in the flute part αa, and the air blown from the water intake port αΦ is also warmed. Becomes the wind. Furthermore, as the temperature inside the inner case (3) rises, the temperature of the inner case (3) also rises, and the air in the space between the inner case (3) and the outer case (4) is also warmed. Thermal efficiency is improved by taking in air from the blower αη. The temperature inside the storage compartment (2) is detected by the temperature sensor mentioned above, and the glue heater ■ is controlled by turning off the electricity so that it does not exceed 80 degrees, and the drying operation is continued for a certain period of time, then stopped and the drying is completed. do.

Note that the present invention is not limited to the above-described structure and control number.

For example, water is supplied from the connection part α9 and the connection part Qυ above the heater ■, so that water is supplied to the heater ■, and at the same time water is supplied, the heater ■ is energized and the pump body (2) is operated. By performing the cleaning operation, the water supply time can be incorporated into the cleaning time.

When the water level detection body is a float switch, the water level detection at this time may be performed by detecting the ON/OFF amplitude by moving the float up and down, or by detecting the flow rate. Heater ■ is connected to α9. Instead of being inserted into I, it may be provided at the lower part of the sheath αa. Also,
It may be arranged so that the connecting portion facing the water intake port α4 is pushed in twice. In this case, during drying, the temperature of the air blown from the water intake port αΦ is higher than the temperature from the nozzle body αD,
Efficient drying can be carried out even if the pump body (2) is stopped.

(G) Effects of the Invention According to the present invention, by disposing the heater within the passage connecting the aquarium and the pump body, the heater is not exposed inside the storage, and safety is improved. Furthermore, by blowing air from the air blower into the passageway, the area where the washing water has flowed can be dried, and water can be completely drained after the operation of the dish washer/dryer is completed, improving durability.・
