DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dishwashing apparatus for washing and drying tableware (also referred to as soups such as bowls and plates, trays, cups and spoons).

[0002]

2. Description of the Related Art A dishwashing apparatus as disclosed in, for example, Japanese Utility Model Publication No. 55-34041 has been used for washing dishes after use.

As shown in FIG. 26, the dishwashing apparatus disclosed in the above-mentioned publication has a structure in which a washing device for blowing out jet water is provided in a washing tank 2 provided in a main body 1. In the washing tank 2, two tableware baskets 4 for accommodating tableware 3 in a shelf format are mounted horizontally, and a water supply valve 5 for supplying water into the washing tank 2 is provided above the washing tank 2. It is arranged. The cleaning device mainly includes a pump 6 and an injection nozzle 7. The pump 6 is mounted below the cleaning tank 2, and the injection nozzle 7 is mounted on the bottom of the cleaning tank 2.

The suction port of the pump 6 is connected to a recess 8 formed at a part of the bottom of the washing tank 2 by a suction pipe 9, and the discharge port is connected to the injection nozzle 7 by a discharge pipe 10.
A garnish filter 11 is mounted in the recess 8 of the washing tank 2, and a drain pipe 12 is connected to the bottom of the recess 8. The spray nozzle 7 is rotatably attached to the discharge pipe 10 by a nozzle bearing 13 and blows water sent from the pump 6 upward from below the lower tableware basket 4. A tower nozzle 14 extends upward at the center of the spray nozzle 7, and the tower nozzle 14 blows water sent from the pump 6 upward from below the upper tableware basket 4.

In the dishwashing apparatus having the above structure, the dishes 3 are stored in each dish basket 4, water is supplied from a water supply valve 5 into the washing tank 2, a detergent 6 is supplied, and then a pump 6 is driven. 3 can be washed. That is, the washing water, which is the detergent-containing water accumulated in the washing tank 2, is sucked into the pump 6 from the recess 8, and is pressure-fed from the discharge pipe 10 to the injection nozzle 7. The spray nozzle 7 rotates together with the tower nozzle 14 by the reaction while spraying the washing water, and cleans the tableware 3 stored in the upper and lower tableware baskets 4. During this time, the washing water is circulated.

After cleaning, the drain pipe 12 is opened and the recess 8 is opened.
The waste water after washing is drained from the drain pipe 12 to the outside.
Garbage and the like mixed in the sewage are collected by the garbage filter 11 and do not flow into the drain pipe 12 or the suction pipe 9. When the washing water is drained, fresh water is supplied from the water supply valve 5 into the washing tank 2, and the water is used to rinse the dishes 3 by the same operation as the washing operation. When the rinsing is completed, the rinsed water is drained, and then the dishes 3 are dried by blowing air from a blower (not shown) to complete the cleaning process.

[0007]

The above-mentioned conventional dishwashing apparatus performs so-called washing with washing water containing a detergent, and thus has a problem that the washing process takes time and effort. In other words, since the washing water stored in the washing tank is circulated and used for washing, the washing water is pre-washed for severely soiled dishes so that the washing effect is not drastically reduced so that the washing effect is not sharply reduced. In addition to having to be placed in a tableware basket, the tableware must be set in such a way that it can be easily washed one by one.

[0008] Further, the removal of dirt is carried out by the detergency of the detergent and the kinetic energy of water, but the degree of dependence on the kinetic energy of water does not cause damage to tableware due to impact or collision with tableware. The processing time is long because the operation is relatively low and similar operations including drainage treatment such as washing and rinsing must be repeated.

[0009] Further, even when washing a small number of tableware less than the capacity of the tableware basket, the amount of water and detergent and the processing time are required regardless of the number of tableware, which is inefficient and easy to use. It also includes issues that are not good.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide an easy-to-use dishwashing apparatus capable of quickly and sanitarily cleaning and quick drying. . Another object of the present invention is to provide a dishwashing apparatus that can easily prevent washing water from splashing outside when washing dishes.

<Description of Drying Apparatus> The drying apparatus basically includes a blower 66 having a suction port facing the inside of the processing tank 22 or the drying-side tank 30, an air flow motor 67 for driving the blower 66, and a blower 66. Tank 2
2, and is set to form an airflow at a speed of about 40 m / sec to 80 m / sec in the processing tank 22. A removable filter 68 is provided at the suction port of the blower 66, and the processing tank 2
The suction of the suspended matter contained in the atmosphere in 2 is prevented. The air flow motor 67 has an outer shell entirely covered with a sound absorbing material 69 to reduce operating noise.

The blowout nozzle 25 is a vertical type having a straight tubular shape having a slit-shaped blowout nozzle hole 70 at a part of the outer periphery. It is connected so as to be able to adjust the rotation by a rotation adjusting mechanism 72 similar to 24. Like the cleaning nozzle 24, this straight tubular blowing nozzle 25 is disposed parallel to the gradient of the opening 21 of the processing tank 22, and the processing tank 2 near the opening 21.
The blowout nozzle hole 70 is mounted higher than the cleaning nozzle 24 so that the blowout nozzle hole 70 faces obliquely downward along the left and right side walls of the inside 2. Each blowing nozzle hole 70 of this blowing nozzle 25
Is a lightweight flat pendulum plate 73 that can rotate in the direction along the blowing direction below the blowing nozzle hole 70.
Are respectively attached in a hanging manner.

The blowing nozzle 25 of a horizontal type has a single blowing nozzle hole 70 at the tip, and the opening 2 of the drying-side tank 30.
The blow-out nozzle holes 70 are connected to the blower pipes 71 piped to the left and right inner walls near 1 so that they can be exchangeably screw-fitted so that the blow-out nozzle holes 70 face slightly downward. In the vicinity of each of the blowout nozzle holes 70 of the blowout nozzle 25, a lightweight flat pendulum plate 73 that can rotate in a direction along the blowout direction below the blowout nozzle hole 70 is attached in a hanging manner. The blow-out nozzle 25 is replaced with a fan-shaped blow-out side as shown in FIGS. 8 and 9 in the case of dish-shaped dishes 20 and a taper as shown in FIGS. 10 and 11 in the case of a cup-shaped dish. Can be freely replaced with a cylindrical one, and an effective drying process can be performed according to the target shape.

This drying device obtains a wind speed at which water droplets adhering to the surface of the tableware 20 can be blown off by overcoming the surface tension acting between the water droplets and the tableware 20. For example, in order to blow off water droplets on a ceramic plate so that only water droplets having a diameter of at most 0.1 mm remain, the water droplets along the plate surface must be from 40 m / sec to 80 m / sec.
It has been confirmed by an experiment that an air flow of sec must be applied, as shown in FIG. And
Generally, 40 m / sec to 8
In order to supply an air flow of 0 m / sec, a blower 66 capable of supplying a large amount of air as well as pressure is required.

In the drying apparatus of this embodiment, the tableware 20 side of the pendulum plate 73 provided in the vicinity of the blow-out nozzle hole 70 of the blow-out nozzle 25 becomes negative pressure by the air flow during the drying process.
Since it is attracted to the tableware 20 and pivots to form a narrow ventilation path between the tableware 20 and the surface, the air flow does not diffuse and remains at a high speed along the profile of the tableware 20. Since it flows, an air flow velocity that can sufficiently blow water droplets even with a small air volume can be obtained.

In the figure, reference numeral 74 denotes an operation panel disposed at an appropriate position on the main body 23, and is provided with various operation switches such as a washing switch and a drying switch. Also, 7
Reference numeral 5 denotes a foot-operated strength adjustment mechanism provided at the lower portion of the main body 23 and capable of changing the pressure of the jet water and the pressure of the air flow.

In the dishwashing apparatus having the above-described configuration, the dishware 20 with dirt is held by hand, and the spouting water spouting into the processing tank 22 from the opening 21 of the processing tank 22 for 3 seconds. When the tableware 20 is held for about 3 to 5 seconds, the washing and drying process of the tableware 20 is completed.

That is, fresh cleaning water heated to a set temperature as required by the cleaning device is pressurized by the pressurizing pump 37, and is continuously and vigorously jetted from the cleaning nozzle 24 into the processing tank 22. If the tableware 20 with dirt is held by hand and held over it, the dirt on the tableware 20 is immediately peeled off by the impact action of the kinetic energy of water and the flushing action of the water flowing down, It is washed down with water at the bottom of the processing tank 22. The dirty water used for the treatment is drained from the drain outlet to the drain pipe 36 without being stopped along the slope of the bottom surface of the treatment tank 22. Since solids and the like in the stripped dirt accumulate in the basket-shaped filter 35, the basket-shaped filter 35 may be appropriately removed and disposed. In the case where the dirt is so severe that it cannot be removed only by warm water, the opening / closing valve 45 is opened and the detergent is put into the water storage tank 39, and the cleaning process can be performed by using the cleaning power of the detergent. Can be sufficiently washed only with warm water.

When the tableware 20 which has been washed and wet with water is held over the high-speed air stream continuously and vigorously jetted into the processing tank 22 from the blowing nozzle 25, the air stream collides with the tableware 20, and the tableware 20 is cut off. It flows along the profile of class 20 to repel water drops. Some of the water droplets will be repelled only by the impact of the air flow, and the tableware 20 will be immediately dried. Especially during this drying process, the dishes 2
By interposing 0 in the air flow, the tableware 20 side of the pendulum plate 73 provided in the vicinity of the blowout nozzle hole 70 of the blowout nozzle 25 becomes negative pressure by the airflow, so that the pendulum plate 73 becomes as shown in FIG. Then, the tableware 20 is attracted to the tableware 20 and rotated, thereby forming a narrow ventilation path between the tableware 20 and the surface of the tableware 20. Therefore, the air flow is not diffused in the processing tank 22 and flows at a high speed along the profile of the tableware 20, and the drying process with a small air volume is realized.

The air in the processing tank 22 is filtered by a filter 68 to remove water droplets and the like, is sucked into a blower 66, and is again blown into the processing tank 22 as an air stream for drying processing. Therefore, since the inside of the processing tank 22 has a tendency to have a negative pressure, water that is blown off or becomes mist-like due to collision is also removed from the processing tank 22.
It never blows out. Tableware 2 for both washing and drying
Since the force due to the jet flow is uniformly applied to the left and right sides, it can be easily held by hand. However, it is possible to construct a simple dishwasher even by squirting only one side.

That is, according to the dishwashing apparatus of this embodiment, a quick and sanitary washing process and a quick drying process with a small airflow can be easily performed. In addition, there is no need for pre-washing or storage washing, and the dishwasher is easy to use because the required amount can be processed when needed.

Embodiment 2 FIG. In this embodiment, as shown in FIG. 14, the pendulum plate 73 of the first embodiment is configured as a curved pendulum plate 76 instead of a flat plate, and other configurations are the same as those of the first embodiment. . According to the curved pendulum plate 76, a narrow ventilation path can be formed for the tableware 20 having a bowl-shaped profile such as a bowl or a bowl, in accordance with the profile.
Effective drying can be performed.

Embodiment 3 FIG. FIG. 15, FIG.
As shown in FIG. 16, the flat pendulum plate 73 of the first embodiment is used.
Is provided on one of the blowing nozzles 25, and the curved pendulum plate 76 is provided on the other blowing nozzle 25.
Is the same as According to this embodiment, the curved pendulum plate 76 and the flat pendulum plate 73 can be used for the tableware 20 having a bowl-shaped profile as shown in FIG. 15 and 16, the applicability is increased as shown in FIGS. Even if the pendulum plate 73 and the curved pendulum plate 76 are provided for one of the blowing nozzles 25, a corresponding effect can be obtained.

Embodiment 4 FIG. In this embodiment, as shown in FIG. 17, the blowing nozzle 25 of the first embodiment
This is configured to be rotated by a rotation mechanism 77. The rotating mechanism 77 may be of an electric type by a drive motor 78 as shown in FIG. 17 or a structural type utilizing the reaction force of the blown air as shown in FIG. In the case of the electric type, the rotation is controlled by means such as a gear train so as to make one rotation per second. In the structural formula, the blow nozzle 25 supported by the bearing 79 is provided with a rotary blow port 80 for blowing in a radial direction.

In this embodiment, the blow-out nozzle 25 is replaceable, and one or two or more blow-out nozzle holes 70 are provided at eccentric positions with respect to the cylindrical base as shown in FIGS. The one shown in FIG. 8 or a slit-shaped one in which the blowing nozzle hole is expanded to the front side is applied.

According to the dishwashing apparatus having the above-described structure, the blowing nozzle 25 is rotated and a conical or columnar wind area is formed by the rotation. Even if the air volume is small, a sufficient drying treatment can be performed. Further, as a result, the air flow hits the surface of the tableware 20 with high and low strength, so that the attached water droplets are easily shaken and blown off, and the drying process proceeds smoothly. In the case where the two blowout nozzle holes 70 shown in FIG. 21 are formed in opposite directions, an inward or outward airflow is formed by rotation.
As shown in the figure, the airflow is not easily blocked by the hill 81 even for the tableware 20 having the hill 81 at the bottom, and a smooth drying process is realized. Other functions and effects are the same as those of the first embodiment.

Embodiment 5 FIG. In this embodiment, as shown in FIG. 23, FIG. 24 and FIG. 25, a structure is provided for blowing out an air stream in a vibrating state. The one shown in FIG. 25 utilizes fluidic oscillation, and a vibrating member 82 that repeats vertical vibration by an air flow is incorporated in the blow-off nozzle 25. FIG.
In FIG. 4, a swash plate 84 that is rotated by a motor 83 is provided obliquely in front of the blowing nozzle hole 70 of the blowing nozzle 25. One rotation of the swash plate 84 causes the swash plate 84 to have the opposite inclination direction, and an air flow similar to a swirling flow is formed. Further, in the configuration shown in FIG. 25, the blow-out nozzle 25 is configured in a hook neck shape, and is caused to vibrate by self-injection. That is, the neck portion 85 has a flexible bellows structure, and the blowing nozzle hole 70 projecting sideways faces the narrow cylindrical guide portion 86 formed on the side wall of the processing tank 22 in a free state.

In this embodiment, the air flow from the blowing nozzle 25 is blown out in a vibrating state in which the direction changes little by little, and the air flow hits the surface of the tableware 20 with high and low strength, and thus adheres. Water droplets are easily shaken and blown off, so that the drying process proceeds smoothly and the air volume is small. The vibration of the air flow can be made faster by using the fluidic oscillation and by using a configuration in which the blowing nozzle 25 itself swings by the reaction of the blowing air hitting the cylindrical guide portion 86 than by rotating the swash plate 84. .

As shown by imaginary lines in FIG.
A blowing nozzle 25 may be provided on the inner surface on the front side of the processing tank 22, so that the air flow also hits the periphery of the tableware 20, and the drying performance can be improved. Further, any of the embodiments 2, 3, 4, and 5 can be applied without distinction between the horizontal type and the vertical type. The ability to form a sufficient air flow for the drying process with a small amount of air can promote reduction in power consumption and noise, resulting in a highly completed device.

[0059]

According to the present invention, the tableware washed by the washing nozzle is moved by moving the tableware held by a person's hand inserted from the opening in the processing tank. Since the washing device and the drying device are sequentially arranged in the treatment tank so as to be able to dry with the blowing nozzle, it is possible to easily wash and dry in the same tank only by moving tableware, An easy-to-use dishwasher can be obtained. Further, since the dishes can be easily washed and dried in the same tank just by moving the dishes vertically, a more convenient dishwasher can be obtained.

Further, in the case of having a space extending below the processing tank, the spray repelled from the tableware or the like being washed is likely to enter the expanded space below the processing tank. The water strikes the wall surface and is trapped on the wall surface, making it difficult for the spray to reach the upper layer of the processing tank, thereby reducing the scattering of the washing water outside the processing tank.

Further, since the widened space is located below the washing nozzle, the spray sprayed from the washing nozzle and colliding with tableware or the like is generated by the washing nozzle when scattered from the tableware or the like. Can easily be trapped in the expanded space below, and the scattering of the spray to the outside of the processing tank can be reduced.

Further, since the direction of jetting the washing water of the washing nozzle is directed toward the widened space, more water droplets and sprays colliding with tableware and the like easily spread to the lower layer side of the treatment tank. This has the effect of making it easier to prevent it from going out of the processing tank.

Further, since there is a partition structure on the wall surface of the processing tank that partially separates the expanded space and the central side of the processing tank, water droplets or sprays that are going to spread further upward from the upper side of the expanded space are removed. Prevents returning to the center of the processing tank,
There is an effect that scattering of the cleaning water to the outside of the processing tank can be reduced.

Further, in the case where the wall surface of the processing tank below the cleaning nozzle is provided with a protruding portion which is directed toward the inside of the processing tank and protrudes from the wall surface, the processing tank wall surface below the protruding portion is provided. There is an effect that the protruding portion blocks the progress of the spray to be blown up along, keeps the spray in the processing tank, and reduces the scattering of the cleaning water outside the processing tank.
