DISCLOSURE OF THE INVENTION The conventional dishwasher / dryer has the following problems.

That is, since the air is blown from the fixed air blow port 40 in a substantially constant direction, the dishes in the cleaning tank 31 cannot be blown uniformly. That is, the drying performance varies depending on the position of the tableware, and the operation time for obtaining the predetermined drying performance is long.

On the other hand, in the proposals by the inventors,
In some cases, the drying time can be shortened by blowing air through the washing nozzle and evenly blowing over the dishes. However, in the embodiment in which the cleaning nozzle is rotated by the cleaning water and the air only by the reaction force of the injection from the same injection hole, the necessary injection angle is obtained by the air. At this time, since the jet water has a large jet reaction force, the number of revolutions of the washing nozzle is too high in the washing process, and the collision angle and the collision force on the dishes change from the optimum state, and the cleaning force decreases.

The present invention solves the problems of the conventional structure as described above, and a dishwasher / dryer capable of obtaining a predetermined washing performance and a shortened drying time by a simple washing / drying mechanism. It is intended to provide.

(Embodiment 2) The basic structure of the mechanical parts is the same as that of FIG. 1 and its explanation is omitted. In FIG. 3, 21 is a cleaning nozzle 20 instead of the above-mentioned first means.
The convex portion 22 on the lower surface is a float. Reference numeral 23 is a nozzle bearing that supports the cleaning nozzle 20, and 24 is a rib provided on the outer periphery of the nozzle bearing 23 to smooth the vertical movement of the float 2. In FIG. 4, reference numeral 25 denotes a concave portion on the side of the float 22 into which the convex portion 21 fits. Further, as shown in FIG. 5, the concave portion 25 has a partition plate 26, and the convex portion 21 can transmit the rotational force of the cleaning nozzle 20 to the float 22.

Next, the operation will be described. The basic operation relating to the cleaning process is the same as in the first embodiment.

When the cleaning water is supplied in the cleaning step, the float 22 floats and the convex portion 21 on the lower surface of the cleaning nozzle 20 fits into the concave portion 25. When the cleaning pump 3 is operated, the cleaning water is supplied from the water supply pipe 8 to the cleaning pump 3 through the suction portion 9, and the cleaning water supply port 1 of the nozzle bearing 11 is supplied from the discharge portion 10.
2 is discharged. At this time, the valve element 14 is pressurized by its own weight and washing water pressure, and the air supply port 13 is closed. Therefore, the washing water is sent to the washing nozzle 4 and is jetted from the jet holes, as in the first embodiment. Here, the rotational force of the cleaning nozzle 20 is transmitted to the float 22 by the partition plate 26 and rotates integrally. Here, the vane portion 27 on the lower surface of the float 22 is immersed in the cleaning water, and the cleaning nozzle 20 rotates at an appropriate number of rotations by agitating the cleaning water, which becomes a resistance to rotation.

In the drying process, the air in the room is sucked into the blower 17 from the intake port 16 and discharged from the blower duct 18 to the air supply port 13. At this time, the valve body 14 is pressurized by a wind pressure exceeding its own weight and moves upward, so that the air supply port 1
Release 3. Therefore, the air is sent to the cleaning nozzle 4 and jetted from the jet holes, as in the first embodiment. Here, the float 22 is located at the inner bottom of the cleaning tank 1 when there is no cleaning water, and the convex portion 2 of the cleaning nozzle 20.
The fitting with 1 is separated. That is, the cleaning nozzle 20 is separated from the float 22, has almost no resistance to rotation, and rotates at an appropriate rotation speed.

With a simple structure, predetermined drainage performance and drying performance can be obtained in a short time, and the operating time can be shortened.

The float 22 is made of a material having a low specific gravity or a hollow molded product and uses buoyancy, so long as it serves as a resistor for the rotation of the cleaning nozzle 20 in the cleaning process.
