(5) is an injection nozzle rotatably supported by a nozzle bearing (4), (6) is a tower nozzle fixed at the center of the injection nozzle (5), and (7) is located immediately above the injection nozzle (5). The tableware (8) is stored in a lower basket supported on the side wall of the inner tub (3).
(9) is an upper basket disposed above the tower nozzle (6) and supported on the side wall of the inner tank (3), and stores tableware (8).

[0004] (10) is a recess formed in a part of the bottom surface of the inner tank (3), and is provided with a garnish filter (11). (12) is a pump, the suction port of which is a recess (10) through a suction pipe (13).
The discharge port of the pump (12) is connected to a nozzle bearing (4) via a discharge pipe (14). (15) is a drain pipe connected to the bottom of the recess (10) and piped outside the main body (1).

[0005] The conventional dishwasher is configured as follows, and the tableware (8) is housed in a lower basket (7) and an upper basket (9) and set in an inner tank (3). Thereafter, the water supply valve (2) is opened, tap water is injected into the inner tank (3), the detergent is mixed, and the pump (12) is driven. With this, the washing water sucked by the pump (12) is discharged through the water discharge pipe (14) and is jetted upward from the jet nozzle (5). Wash (8). Similarly, the tower nozzle (6) also rotates by spraying washing water to wash the tableware (8) in the upper basket (9).

[0006] The washing water that has washed the tableware (8) in this way falls in the inner tank (3) and flows into the recess (10). Then, it is cleaned by the garbage filter (11), sucked into the pump (12), supplied again from the discharge pipe (14) to the injection nozzle (5) and the tower nozzle (6), and the washing water is circulated and washed. Repeat the operation. Then, when the washing with the detergent is completed, the polluted water is drained through the drain pipe (15).

Thereafter, fresh water is supplied again through the water supply valve (2), and the water is sprayed from the spray nozzle (5) and the tower nozzle (6) for rinsing as in the case of washing. After rinsing, drain again. And finally the blower
The tableware (8) is blown by a fan (not shown) to dry the tableware (8).

[0008]

In the conventional dishwasher as described above, the washing water discharged by the pump (12) is jetted, and the tableware (8) stored in the baskets (7) and (9). The following problems are caused because the cleaning is performed.

(1) It takes time and effort. a. Tableware (8) must be set in baskets (7) and (9) so that they can be easily washed one by one. b. Washing the tableware (8), which is very dirty, to wash with the water stored in the inner tank (3) increases the amount of dirt in the washing water,
Cleaning must be incomplete. Therefore, it is necessary to pre-wash and remove large dirt before washing with a dishwasher.

(2) Washing cannot be performed with strong water flow. Since the tableware (8) was only placed in the baskets (7) and (9), if the jet of washing water was increased, the dishes (8) could be placed in the baskets (7) and (9).
There is a possibility that the tableware (8) may be damaged due to collision in the interior. That is, the jet pressure of washing water in a conventional dishwasher is 0.5 kg / cm.
It is considered appropriate to set it to about ² , and at most 1 kg / cm
A pressure of less than ² was used. Therefore, since it cannot be washed with a strong water flow, a strong dedicated detergent is indispensable for promoting the washing. (3) It takes time. As described in (1) above, the setting of the tableware itself is troublesome and troublesome, and it is necessary to heat the washing water with a heater in order to improve the washing effect, and the heating time, washing time, washing water drainage time and rinsing are required. There is a problem that time is required and the number of processing steps is large.

(4) Washing with fresh water cannot be performed. When the cleaning water becomes dirty, and the cleaning is performed while replacing the fresh water, the temperature of the cleaning water decreases and the concentration of the detergent decreases. (5) You can only store and wash (wash when the number of dishes is gathered to some extent). a, Since the amount of washing water and the washing time are constant regardless of the number of dishes (8), the use of the dishwasher when the number of dishes (8) is small is inefficient. b. When storing and washing, dirt dries or solidifies during the standing time, so that dirt hardly falls off.

The operation of the dishwasher configured as described above will be described. When the dishwasher is not used, the opening (21b) is closed by the lid (22) as shown in FIG. 2A, and when used, the lid (22) is used as shown in FIG. 2B. Is turned upward to open the opening (21b). The inside of the lid (22) is used as a temporary storage space for the tableware (8) during the washing operation. Water absorption pipe
Tap water supplied from (25) is stored in a water storage tank (26), and the water level in the tank (26) is kept constant by a ball tap (27).

Here, the pressurizing pump (29) is connected to the water storage tank (2).
It is installed below 6), so that the inside of the pump (29) is always filled with water. That is, the pump
If the pump (29) is located above the water storage tank (26), the liquid level (water level) of the water storage tank (26) is open to the atmosphere when the pump (29) is stopped. The water in the storage tank (2
Returning to step 6), the pump (29) runs out of water. When the operation of the pump (29) is started from this state, the pressure inside the pump (29) once becomes negative pressure,
After sucking water from 6), water enters pump (29).

As described above, when the water and the air are mixed and compressed to a high pressure, cavitation occurs and causes the structure to be destroyed. If the pump (29) is installed below the water storage tank (26), the inside of the pump (29) will always be the water storage tank (26).
Filled with water from the air and no air is mixed.

When the temperature of the washing water is set by the temperature setting device (52), and the jet water switch (53) and the air flow switch (54) are operated, the jet water motor (30) and the air flow motor (42)
Is driven. When the motor (30) rotates, the pressurizing pump
(29) is driven, and the cleaning water is pressurized and led to the pipe on the discharge side. On the other hand, in the heating device (28), the cleaning water is heated by the heater to a temperature suitable for cleaning (a temperature at which the user does not feel cold and does not cause danger such as a burn even when touching the cleaning water). Thus, the heated and pressurized washing water is branched by the branch pipe (32), supplied to the jet water nozzle pipe (33), and jetted from the nozzle (34).

As shown in FIG. 4, the user holds the tableware (8) by hand and inserts it through the opening (21b) between the nozzle tubes (33) and (33). The high-speed water jet spouted from the nozzle (34) collides with the tableware (8), and the impact force and the action of the water flowing down cause the tableware (8) to drop.
The dirt adhering to (8) is removed, and the tableware (8) is washed.

The direction of injection from the nozzle (34) is set below horizontal as shown in FIG. This is because, when directed horizontally or in the direction of the opening (21b), the water that collides with the tableware (8) and scatters in each direction may jump out of the opening (21b), and it is easy to wash off dirt removed. To do that. The direction of this nozzle (34) is loosened by loosening the flange nut (36a) of the jet water nozzle rotation mechanism (36), and the nozzle pipe (33)
Can be easily changed by rotating the flange nut (36a) again.

The fresh water from the water storage tank (26) can be used to remove dirt attached to tableware by a water force of approximately 2 kg / cm ² or more.
kg / cm ² or less, this value is sufficient to obtain a sufficient cleaning effect and does not cause pain even when the jet water hits the hand, and the cleaning can be completed in 3 to 5 seconds per piece of tableware . The amount of water required for washing is generally a flow rate (20 liters / min or less) that can be supplied from water supply. If a large flow rate is required for washing, a large water storage tank (26) is required to secure the flow rate, and the dishwasher becomes large. However, if the flow rate, because it is within the supply flow rate from the water, there is no limitation by the flow, it is successively washed. The water storage tank (26) may have a minimum capacity.

Since the jet water is very fast, the washing space
In order to generate noise when colliding with the wall constituting (21a), a sound absorbing material (24) is arranged on the wall to prevent sound. Similarly, a sound absorbing material (41) is also provided in the air flow motor (42) so as to suppress noise due to high-speed rotation.

On the other hand, by driving the air flow motor (42),
The high-speed air flow is led to the air nozzle pipe (37) and the air nozzle
Ejected from (38). Since the air nozzle (38) is located above the jet water nozzle (34) and slightly downward, the air discharged from the nozzle (38) collides with the tableware (8), and the tableware (8) ) Is carried along the tableware (8) to the end thereof. Since the force of the discharged air is greater than the surface tension of water at the end of the tableware (8), water droplets are scattered, and as a result, the tableware (8) is dried. Some of the water droplets
The discharged air scatters only due to the collision. These states are shown in FIG. The air pressure at which water droplets attached to the tableware (8) can be blown off is 100 mmH ₂ O or more and 500 mm or more.
H ₂ O or less is set. According to this value, it can be completed in about 3 to 5 seconds only by the drying time.

The air flow that has dried the tableware (8) is supplied to a blower (4).
0) is sucked in from the air suction port (43), and the nozzle pipe (3
7) and circulates in the washing space (21a). If not circulated, the air discharged into the washing space (21a) will come to the outside through a part of the opening (21b), and water droplets will also leak outside due to this air flow. In addition, since the air is discharged above the jet water,
In addition to drying (8), it also acts as an air curtain. That is, fine mist-like water droplets generated by squirting from the nozzle (34) and colliding with the tableware (8) at high speed are opened.
(21b) Prevent from coming outside. The filter of the air inlet (43) prevents water droplets from being sucked into the blower (40). Also, the discharged air flow is open
It is desirable that the ink be ejected with a slight downward inclination as viewed from (21b).

The filth washed off by the jet water is collected in a trash collection basket (47), and water is discharged from a drain pipe (48). If there is dirt that cannot be removed with the jet water alone, operate the detergent switch (51) to open the detergent shutoff valve (45), and store the detergent in the detergent container (44) in the water storage tank (2).
Supply to 6). With this, it is possible to wash with the washing water mixed with the detergent.

In such a dishwasher, the tableware (8) to be washed is inserted into the washing space (21a) of the main body (21) and is exposed to fresh water for a few seconds. ), The work process is completed just by exposing, and unlike the conventional one, the drainage process and the rinsing process are not required, and since there is no repetition, the dishes can be washed very easily and in a short time (5 to 10 seconds). It is possible and sanitary.

Further, the cleaning can be carried out as needed when necessary, so that the efficiency is high. Furthermore, there is no need for pre-washing, and no detergent is required except in special cases. In addition, since the jet water nozzle (34) is disposed on both sides, the front and back of the tableware (8) can be washed at once, so that the washing water jetted at a high pressure does not tire the hands and can be washed in a shorter time. And the tableware (8) pulled out from the main body (21) can be stored immediately. Since the cleaning time is extremely short, the actual amount of water used does not become excessive.
