The ultrasonic vibration unit 5 includes a power source 6 for supplying electric power to the ultrasonic vibration unit 5.

The container 3 has an air outlet 3a at an upper part and a drain hole 3b at a lower part. The air outlet 3a communicates with the outside air, and in this embodiment, an air blowing means 15 composed of a fan is provided here. The drain 3b is provided with a drain 13 formed by an electromagnetic valve. Drainage means 13
Is connected to a drain hose 14 for discharging washing water to the outside of the apparatus. An ultrasonic element 25 driven by the ultrasonic vibration means 5 is provided at the bottom of the container 3.

In this embodiment, the power supply 6 is provided in the main body 10.
And a shaping means 16 for shaping the waveform of the output to a direct current. The shaping unit 16 supplies power to the ultrasonic vibration unit 5 and the stroke control unit 17. Travel control means 17
According to a built-in control program, the water supply control means 11, the ultrasonic vibration means 5, the drainage means 13,
The blowing means 15 is driven.

The power supply means 20 has a switching means 7 connected to the commercial power supply 9, a control means 8 controlling the switching means 7, and a power supply means 12 connected to the switching means 7. are doing.

In the present embodiment, the power supply 6 and the power supply means 12 are constituted by coils, and are arranged at positions where they are electromagnetically coupled. That is, the power supply 6 receives power supplied from the power supply means 12 in a non-contact manner.

The operation of this embodiment will be described below. When a start switch (not shown) is pressed, the cleaning device starts operating. That is, the switching means 7 and the control means 8 constituting the power supply means 20 convert the voltage of the commercial power supply 9 to a high frequency of, for example, about 20 kHz and drive the power supply means 12. The power supply means 12 generates an alternating magnetic field having the same high frequency as the applied high frequency. This alternating magnetic field links with the power supply 6 which is electromagnetically coupled to the power supply means 12. Therefore, a similar high-frequency voltage is also generated in the power supply 6. The high-frequency voltage is shaped into a direct current by the shaping means 16 and transmitted to the stroke control means 17.

FIG. 3 is an explanatory diagram showing a control program of the stroke control means 17 of this embodiment. That is, the stroke control means 17 first executes the water supply stroke a. That is, the electromagnetic valve constituting the water supply control means 11 is opened for a predetermined time, and a predetermined amount of tap water is stored in the container 3 from the tap 1. When the water supply step a is completed, the washing step b is subsequently executed. That is, the ultrasonic vibration means 5 is driven to vibrate the ultrasonic element 11 provided at the bottom of the container 3. In the present embodiment, the ultrasonic vibration unit 4 oscillates at, for example, 40 kHz and drives the ultrasonic element 3. The ultrasonic element 3 vibrates the bottom surface of the container 2 so that 4
An ultrasonic vibration of 0 kHz is applied. Therefore, countless cavitations are generated in the washing water in the container 3, and the generated cavitations burst. When the cavitation bursts, a very large mechanical force is generated. This mechanical force acts on an object to be washed such as tableware in the basket 4 housed in the container 3. Therefore, the object to be cleaned is cleaned by receiving a large mechanical force from the cavitation generated by the ultrasonic vibration during the cleaning process b. Of course, the user may put the detergent into the container 2 at the timing of this washing step B. In this case, the object to be cleaned is cleaned by the chemical force of the detergent in addition to the mechanical force, and the cleaning effect is further enhanced.

When the cleaning process for a predetermined time is completed in this way, the process control means 17 subsequently executes a drainage process C.
In the drainage stroke C, the stroke control means 17 includes the water supply control means 1.
The drain means 13 is opened with 1 closed. When the drainage means 13 is opened, the washing water after washing the object to be washed in the container 3 is discharged from the drainage hose 14 to the outside of the apparatus.

When the drainage stroke C for a predetermined time is completed, the stroke control means 17 subsequently executes the rinsing stroke D and the drainage stroke E. Of course, the rinsing step d and the draining step e may be repeated several times as necessary. In the rinsing step d, the water supply control means 11 is opened with the drainage means 13 closed, and a predetermined amount of washing water is again supplied to the container 3.
In this state, the water supply control means 11 is closed, the drainage means 13 is opened, and the rinsing water is drained.
Thus, when the last drainage stroke E is completed, the stroke control means 17 subsequently executes a drying step.

In the drying step, the process control means 17 energizes the blowing means 15 to blow outside air into the container 3 from the blowing port 3a. The object to be cleaned after drying and rinsing is dried by the blowing of the outside air.

At this time, in the present embodiment, as shown in FIG. 2, the main body 10 is disposed on the cooking table 21. FIG.
FIG. 3 is a perspective view showing a sink to which the cleaning device of the present embodiment is attached. A power supply means 20 is disposed on the lower surface of the cooking table 21 at a position facing the main body 10. That is, only the main body 10 of the cleaning device of the present embodiment is placed on the cooking table 21. The drain hose 14 is connected to a sink provided on a cooking table 16.

The main body 10 has a watertight structure except for the basket 4 and the opening for accommodating the object to be cleaned. Also, the main body 10
The power supply means 20 provided on the lower surface of the cooking table 21 is connected electromagnetically inductively. Therefore body 1
No water enters the space in which the 0 electrical components are housed or the power supply means 20. That is, the reliability against water intrusion is sufficiently ensured.

When the water supply hose 2 is removed, the body 10
Since there is no other connecting part, it can freely move on the cooking table 21. That is, when not in use, it can be put away at the corner of the cooking table 21.

Further, since the main body 10 does not use a heavy object, it is very small and lightweight as compared with a conventional cleaning apparatus. Therefore, handling becomes very easy.
