[0008]

In the conventional dishwasher as described above, the washing water discharged by the pump (12) is sprayed to the dishes (8) stored in the baskets (7) and (9). Since it is designed to be washed, there are the following problems.

(1) It takes time and effort. a. The dishes (8) must be set one by one in the baskets (7), (9) to facilitate cleaning. b. Since it is washed with the water stored in the inner tank (3), if the dishware (8), which is very dirty, is washed, the stains on the washing water increase,
There is no choice but to complete the cleaning. Therefore, it is necessary to pre-wash and remove large dirt before washing with a dishwasher.

(2) It cannot be washed with a strong water stream. The dishes (8) were only placed in the baskets (7) (9), so if the jet of washing water is made strong, the dishes (8) will be in the baskets (7) (9).
There is a risk of colliding inside and damaging the dishes (8). That is, the jet pressure of washing water in the conventional dishwasher is 0.5 kg / cm.
It is thought that about ² is appropriate, and the maximum is 1 kg / cm.
A pressure of less than ² was used. Therefore, it cannot be washed with a strong stream of water, so a powerful, dedicated detergent is essential to promote washing. (3) It takes time. As in (1) above, setting the dishes is troublesome and troublesome, and in order to improve the cleaning effect, it is necessary to heat the cleaning water with a heater, and the heating time, cleaning time, cleaning water draining time and rinsing time are required. There is a problem that time is required and the number of processing steps is large.

(4) It cannot be washed with fresh water. When the cleaning water becomes dirty, when the cleaning water is replaced with fresh water, the temperature of the cleaning water decreases and the detergent concentration decreases. (5) You can only store and wash (wash when the number of dishes has been collected to a certain extent). a. Since the amount of washing water and the washing time are constant regardless of the number of dishes (8), use of the dishwasher when the number of dishes (8) is small is inefficient. b. When the stored and stored washing is carried out, the stains are dried or solidified within the standing time, so that the stains are hardly removed.

The present invention has been made to solve the above problems, and provides a dishwasher which can be always washed with fresh water, the washing time can be shortened, and the drying can be performed easily and in a short time. The purpose is to

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

Here, the pressurizing pump (29) is a water storage tank (2
It is installed under 6), so that the inside of the pump (29) is always filled with water. Ie pump
If the water tank (26) is located above the water storage tank (26), the liquid level (water surface) of the water storage tank (26) is open to the atmosphere when the pump (29) is stopped. The water in the water tank (2
After returning to 6), there is no water in the pump (29). If the pump (29) is started in this state, the inside of the pump (29) will once have a negative pressure and the water tank (2
After sucking water from 6), water comes into the pump (29).

As described above, when water and air are mixed and compressed to a high pressure, cavitation occurs, which causes destruction of the structure. 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 and no air entraps.

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, pressurization pump
(29) is driven, and the wash water is pressurized and guided to the discharge side pipe. On the other hand, in the heating device (28), the heater heats the wash water to a temperature suitable for washing (a temperature at which the user does not feel cold and does not cause a risk of burns or the like even when touching the wash water). Thus, the heated and pressurized cleaning water is branched by the branch pipe (32), supplied to the jet water nozzle pipe (33), and ejected 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 stream ejected from the nozzle (34) collides with the tableware (8), and due to the impact force and the action of falling water, the tableware
Remove the dirt attached to (8) and wash the dishes (8).

The jetting direction from the nozzle (34) is set lower than horizontal as shown in FIG. This is because when it is directed horizontally or in the direction of the opening (21b), the water that has collided with the tableware (8) and splashed in each direction may jump out from the opening (21b), and it is easy to pour off the scraped waste. This is because The direction of this nozzle (34) loosens the flange nut (36a) of the jet water nozzle rotation mechanism (36), and the nozzle pipe (33)
After turning, the flange nut (36a) can be tightened again to easily change the position.

The fresh water from the water storage tank (26) is capable of removing dirt adhering to dishes from a water force of approximately 2 kg / cm ² or more 20
It is less than kg / cm ² , and this value is sufficient to obtain a cleaning effect and does not cause pain even if the jet water hits the hand, and cleaning can be completed in 3 to 5 seconds per dish. . In addition, the amount of water required for cleaning is generally a flow rate (20 liters / minute or less) that can be supplied from a 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, with the above flow rate, since it is within the flow rate supplied from the water supply, there is no limitation due to the flow rate, and continuous cleaning is possible. The water tank (26) need only have a minimum capacity.

Since the jet water is very fast, the washing space
Since noise is generated when it collides with the wall surface forming the (21a), the sound absorbing material (24) is arranged on the wall surface to prevent noise. Similarly, the air flow motor (42) is also provided with a sound absorbing material (41) to suppress noise due to high speed rotation.

On the other hand, by driving the air flow motor (42),
The high-speed airflow is guided to the air nozzle tube (37) and the air nozzle
Eject from (38). Since the air nozzle (38) is located above the jet water nozzle (34) and is directed slightly downward, the air discharged from the nozzle (38) collides with the tableware (8) and the tableware (8). The water droplets adhering to () are carried along the tableware (8) to the end thereof. Since the force of the discharged air exceeds the surface tension of water at the edge of the tableware (8), the water droplets are scattered and as a result, the tableware (8) is dried. Also, some of the water droplets
It is scattered just because the discharged air collides. These states are shown in FIG. The air pressure that can blow off the water droplets attached to the tableware (8) is 100 mmH ₂ O or more and 500 mm or more.
It is set below H ₂ O. According to this value, the drying time alone can be completed in about 3 to 5 seconds.

The air flow obtained by drying the tableware (8) is blown by the blower (4
It is sucked in through the air suction port (43) of
It is supplied to 7) and circulates in the cleaning space (21a). If it is not circulated, the air discharged into the cleaning space (21a) will come out through a part of the opening (21b), and the water flow will also leak water droplets to the outside. Also, since the air is discharged above the jet water,
Not only does (8) dry, it also acts as an air curtain. That is, the fine mist-like water droplets that are generated by ejecting from the nozzle (34) and colliding with the tableware (8) at high speed are opened.
Prevent from coming out from (21b). The filter of the air suction port (43) prevents water droplets from being sucked into the blower (40). In addition, the discharged air flow is open
It is desirable that the discharge be performed with a slight inclination as viewed from (21b).

The filth washed off by the jet water is collected in the filth collection basket (47), and the water is discharged from the drain pipe (48). If there is dirt that cannot be removed by 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 tank (2).
Supply to 6). With this, it is possible to wash with washing water mixed with detergent.

In such a dishwasher, the dishwasher (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, and then the dishwasher (8) is exposed to the discharged air. ) Is completed, the work process is completed, unlike the conventional one, there is no need for draining process and rinsing process, and there is no repetition, so it is extremely easy and the dishes are washed in a short time (5 to 10 seconds). It can be done and is hygienic.

Further, it is efficient because it can be washed as many times as necessary. Furthermore, there is no need for prewashing, and no detergent is required except in special cases. Further, since the jet water nozzles (34) are arranged on both sides, the front and back of the tableware (8) can be washed at a time, so that the hands are not tired by the washing water jetted with a strong pressure, and the dishes 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.

Example 2. FIG. 7 is a view showing another embodiment of the nozzle portion for jet water according to the present invention. Like the first embodiment, the nozzle pipes (33) are arranged on both sides, and the nozzles (34) are attached to the tips thereof. .

Example 3. FIG. 8 is also a view showing another embodiment of the nozzle portion for jet water of the present invention, in which the nozzle pipe (33) is arranged on both sides, and a plurality of jet outlets (nozzles) (34) are provided on the side surface of the nozzle pipe (33). ) Is open.

Example 4. FIG. 9 is a perspective view showing another embodiment of the pressurizing pump and the jet water nozzle tube portion of the present invention. One pressurizing pump (29) has two pressurizing pumps (29A) (29B).
Drive the nozzle tube (33A) (33B) for each pump (29A) (29B)
And the nozzles (34A) and (34B) are mounted respectively. Therefore, the pressure and flow rate can be set for each nozzle (34A) (34B).

Example 5. FIG. 10 is also a perspective view showing another embodiment of the pressurizing pump and the jet water nozzle tube portion of the present invention. Two pressurizing pumps (30A) and (30B) respectively drive the pressurizing pumps (29A) and (29B). However, the nozzle tubes (33A) and (33B) are provided for each of the pumps (29A) and (29B), and the nozzles (34A) and (34B) are mounted respectively. Therefore, the pressure and flow rate of each nozzle (34A) (34B) can be controlled, and a dishwasher with good controllability can be obtained.

In each of the above-mentioned embodiments, since the jet water is supplied from both sides of the tableware (8), force is applied to both sides of the tableware (8) at the same time, and the tableware (8) is not shaken to one side. It is possible to reduce the force holding (8). However, even if the nozzle tube (33) is only on one side and the jet water is supplied only from one side of the tableware (8), the holding force by hand is only slightly increased, and it is practically possible. The configuration is simple and inexpensive.

Example 6. FIG. 11 is a perspective view showing another embodiment of the air nozzle tube portion of the present invention.
2) Drive two blowers (40A) (40B), suck air from each suction port (43A) (43B), blower (40A) (40B) air nozzle tube (37A) and drying respectively An air nozzle pipe (37B) for preventing water droplets from scattering was connected. Nozzle tube (37
The nozzle (38A) of (A) is opened obliquely downward, and the nozzle (38B) of the nozzle tube (37B) is opened in a substantially horizontal direction with the opening (21b).

The air flow from the nozzle (38A) dries the tableware (8) as described above, and the air flow from the nozzle (38B) causes water to collide with the tableware (8) to form fine mist-like water droplets. Acts as an air curtain to prevent air from coming out of the opening (21b). At this time, the air amounts of the nozzles (38A) and (38B) are set equal to each other or the number of nozzle tubes (38B) is reduced. This is because atomized water droplets are sufficiently small compared to water droplets for cleaning,
This is because a small amount of air is required to prevent the atomized water droplets from coming out of the opening (21b).

Example 7. FIG. 12 is a sectional view showing another embodiment of the nozzle tube of the present invention. In this embodiment, the nozzle pipes (33) (37) of the above-mentioned embodiment are integrated, and the nozzle pipe (33) for jet water is arranged in the nozzle pipe (37) for air to form an integrated nozzle pipe. (59) is formed. And the nozzle (3
8A) is arranged obliquely downward, and the nozzle (38B) is arranged substantially parallel to the opening (21b). Now each nozzle tube (33) (3

Example 10. FIG. 15 is an internal perspective view showing another embodiment of the present invention. The nozzle tube (3
It uses an integral nozzle tube (60) in which 7A and 37B are integrated. In the integrated nozzle pipe (60), one pipe is provided with air discharge ports in two stages, or one pipe is divided into two stages along the axis to provide air discharge ports communicating with each other, The lower ejection port is used as a drying air nozzle and the upper ejection port is used as a water droplet scattering prevention air nozzle.

Example 11. FIG. 16 is a transverse sectional view of a cleaning space portion showing another embodiment of the present invention. In each of the above embodiments, the air nozzle (38) is arranged above the jet water nozzle (34), but in the eleventh embodiment, the nozzles are arranged front and back (or left and right), and in FIG. ), A jet water nozzle (34) is arranged in the rear part, and an air nozzle (38) is arranged in the front part. Therefore, the dishes (8) are washed in the rear part of the washing space (21a), and after the washing is finished, they are moved to the front part and dried.

Example 12 In the above embodiment, the tableware (8) is washed with jet water and dried with an air flow, but it is also possible to combine a drying means with an air flow with a washing means with a circulating water flow. That is, if a drying means using an air flow is incorporated into an ordinary dishwasher, it can be dried immediately after washing, which is sufficiently useful.

Example 13 In each of the above-mentioned embodiments, it is possible to continuously discharge the jet water and the discharge air at the same time, but it is also possible to provide a foot pedal for separately controlling each of the jetting amount and the discharge amount to perform the manual operation. That is, only the jet water may be operated, only the discharge air may be operated, or both operations may be performed simultaneously while controlling both operations separately.

Example 14 In each of the above embodiments, the cleaning space
