Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a foam cleaning machine for foaming a cleaning liquid and cleaning objects to be cleaned such as dishes and machine parts with the cleaning foam, and particularly a cleaning foam supply line. Regarding the improved structure of.

(Prior Art) Conventional foam cleaning machines are disclosed in JP-A-60-103930 and JP-A-6-103930.
As represented by the structure disclosed in Japanese Patent Publication No. 0-165942, a foaming portion is directly connected to the bottom portion of the cleaning tank, and a foaming plate for uniformly performing foaming without unevenness is provided horizontally. It has a drainage port below it.

(Problems to be solved by the invention) In the case of the above-mentioned conventional structure, when the cycle of cleaning → rinsing required for cleaning is carried out, when the cycle is completed, the foamed plate (a punching plate is generally used) is placed on the foam plate. Soil and other dirt that originally adhered to the tableware will drop and come into contact with it.As a result, during the next cycle, fresh detergent foam will come into contact with the dirty foam plate and fine dirt will occur in sequence. There is a problem in that the cleaning power is lowered by being lifted up to the cleaning tank side by the generated cleaning bubbles. This is the same when cleaning other articles.

Further, the load of the detergent liquid head on the foam plate causes a large torque at the time of starting the blower, which causes a problem that the blower has a large capacity.

The present invention has been made to solve such a problem, and in particular, it has an arrangement form of a detergent liquid chamber and a detergent liquid tank for feeding cleaning bubbles to a foaming chamber immediately below a cleaning tank. By devising ingenuity, fresh cleaning foam will not be contaminated by the time it comes in contact with the object to be cleaned, and the load on the foaming fan during initial foaming will be reduced, improving cleaning performance and making the device compact. That is the purpose of the invention.

(Means for Solving the Problems) Then, as is apparent from the drawings showing the embodiments of the present invention, the cleaning liquid in the cleaning tank (2) is replaced by the detergent liquid holder (1).
A foam washer that repeats the cycle by washing with the foam of the detergent solution held by 3), and after washing, draining the foam from the bottom of the washing tank (2) and rinsing is one cycle of washing. In the lower part of the cleaning tank (2) for storing the object to be cleaned, a foaming chamber (3) having a side wall is provided so as to be directly connected to the cleaning tank (2), and a drain pipe (11) is connected to the foaming chamber (3). On the other hand, the hole (6) is opened in the side wall, and the detergent solution chamber (5) containing the detergent solution holder (13) capable of holding the detergent solution by impregnation is provided in the hole (6). The foaming chamber (3) is disposed so as to face the side wall of the foaming chamber (3) and the foaming fan (7) is connected to the detergent liquid chamber (5). 4) is separately disposed above the detergent liquid chamber (5), and the liquid pipe (14) is placed in the detergent liquid chamber (5).
It is characterized by being connected by.

Further, the present invention is a preferred embodiment in which an opening / closing valve (15) for opening the fan (7) at an appropriate timing after starting is provided in the middle of the liquid pipe (14).

(Operation) Next, the operation of the above-mentioned washing machine will be explained in terms of the most general operation, for example, washing of dishes. When the washing / rinsing operation is completed, drainage operation is performed to wash the washing tank (2).
Foreign matter such as leftovers inside will be discharged to the outside of the tank by the drainage pipe (11) through the foaming chamber (3) where there are no obstacles at all, and the cleaning bubbles will be generated through the hole (6) on the side wall. (3) Since the structure is fed into the inside, fresh foam immediately after generation does not come into contact with the leftovers and the like, and the cleaning power can be doubled.

On the other hand, for the fan (7), only the detergent liquid holder (13) impregnated with the washing liquid acts as a resistance to the circulating air, so the detergent liquid head is small and the fan (7) has a small capacity. Any thing can be used.

Also, do not replenish the detergent solution holder (13) with detergent solution.
(7) By making it take place after the operation,
It is possible to prevent dripping due to excessive supply and save consumption of detergent liquid.

(Embodiment) The contents of an embodiment of the present invention will be described below with the dishwasher shown in the accompanying drawings as an example.

FIG. 1 shows a dishwasher according to an example of the present invention, in which a casing (1) contains a washing tank (2) for storing dishes to be washed and a washing tank (2) for washing the dishes. Face the foaming chamber (3) integrally provided directly below the bottom of the cleaning tank (2) and the hole (6) provided at an intermediate position of a side wall of the foaming chamber (3), for example, a vertical side wall. A detergent liquid chamber (5) provided, a detergent liquid tank (4) connected to the detergent liquid chamber (5) by a liquid pipe (14) having an opening / closing valve (15), a fan (7) and A warm air generator having a heater (8) for supplying warm air to the detergent liquid chamber (5), and a drain valve (12)

And a water supply pipe (10) connected to.

The cleaning tank (2) has a foam discharge passage (16) connected to the upper side wall, and the bottom is formed into a mortar shape, and a foam chamber (3) surrounded by a vertical side wall is formed at the bottom of the center. It is attached integrally.

On the other hand, the detergent liquid chamber (5) facing the hole (6) is the foaming chamber.
It is placed on the side of (3) and has a detergent solution holder inside the room.
(13) is filled and stored.

The detergent liquid holder (13) may be impregnated with a liquid such as a sponge having a large number of communicating cells such as a sponge, a polymer obtained by stacking a large number of fiber fabrics, a lump in which fibers are intersected, or a honeycomb structure in a wet state. It is formed of a porous body, and each example is housed in the detergent liquid chamber (5) so that it can be inserted into and removed from the detergent liquid chamber (5), as shown in FIGS. 2 to 5.

The one shown in FIGS. 2 and 3 is the opening side after the detergent solution holding body (13) formed in a disk shape is filled in the detergent solution chamber (5) having a peripheral wall forming a short cylinder with two flanges. Packing on both ends of the collar (19)
And a circular perforated plate (20) are brought into contact with each other, and sandwiched between the vertical side wall of the cleaning tank (2) and the tip of the warm air duct (21) to fix them.

In addition, (17) is a hole so that water does not hit directly during rinsing.
An eaves-like water shield provided in the upper part of (6), and (18) guides foreign substances such as leftovers to fall into the detergent liquid chamber (5) through the window (6). Each shows the filter for receiving the leftovers for prevention.

On the other hand, FIG. 4 shows that the detergent solution holder (13) has a cylindrical columnar cartridge structure so that it can be fitted into the detergent solution chamber (5) from the inside of the foaming chamber (3) through the hole (6). FIG. 5 shows an example in which the detergent solution holder (13) is housed in a flanged container having a shape corresponding to that shown in FIG. 4, and similarly has a cartridge structure.

In addition, in both of the examples shown in FIGS. 4 and 5, it is possible to optionally provide a water blocking plate (17) or a residual food receiving filter (18).

Next, the detergent liquid tank (4) is provided as an independent separate body in the casing (1) above the detergent liquid chamber (5), and is provided at the bottom of the liquid chamber (5). The outlet and the liquid supply port (22) provided on the top of the peripheral wall of the detergent liquid chamber (5)
For example, it is connected by a liquid pipe (14) with an electromagnetic valve interposed, and the detergent liquid tank is opened by opening the open / close valve (15).
The detergent liquid in (4) naturally flows down by gravity and is fed into the detergent liquid chamber (5) and permeates into the detergent liquid holder (13).

The thus configured washing machine cleans dishes in the operating modes described below.

Store dishes in the washing tank (2), drive the fan (7), and heater.
(8) is operated by energizing it to generate hot air at 60 to 65 ° C in the detergent solution chamber.
Send to (5).

After a slight time lag from the start of hot air supply, the solenoid valve (1
When 5) is opened, the detergent solution in the detergent solution tank (4) flows down to wet the detergent solution holder (13) in the detergent solution chamber (5).

Thus, a large amount of detergent bubbles of 60 to 65 ° C. are generated from the holes (6) by the action of the warm air, and the detergent bubbles flow into the foaming chamber (3) and are then sent into the cleaning tank (2).

This cleaning foam (detergent foam) rises from the bottom and is washed in the cleaning tank.
(2) The bubbles are washed by filling the inside of the tableware and contacting the surface of the tableware, but due to the continuously pushing up action of the bubbles, the bubbles above contribute to the washing, and the bubbles above the bubble discharge passage (16). And then discharged to the outside of the tank.

When the washing of the dishes is completed by the contact with the washing bubbles that are sequentially replaced with the elapse of a predetermined time, the fan (7) is stopped, the solenoid valve (15) is closed, and the drain valve (1
Open 2). The heater (11) continues the heating operation by automatic temperature control.

When a dozen or more seconds have passed since the opening of the drain valve (12), the liquid containing bubbles in the foaming chamber (3) is completely discharged from the drain pipe (11), and the chamber is emptied.

At this point, if the drain valve (12) is closed and the fan (7) is driven, warm air will pass through the foaming chamber (3) and the washing tank (2)
The cleaning bubbles that flow into the tank and fill the tank rapidly due to this hot air rapidly break into a small amount of detergent liquid, creating a foaming chamber.
Run down to the bottom of (3).

When the bubble breaking (defoaming) operation in the above-described operation mode is performed for several minutes and the bubbles disappear in the cleaning tank (2), the fan (7) is stopped and the heater (8) is de-energized.

At the same time, both the drain valve (12) and the water supply valve (23) at the end of the water supply valve (10) are opened to start the rinse operation.

Thus, the rinsing water sprayed from the rinsing nozzles (9) and (9) is rinsed by removing the residual foods adhering to the tableware and slightly remaining bubbles, and mud to be drained from the drain pipe (11).

Since the above rinse operation is performed after the bubble breaking operation, the dishes can be surely rinsed in a short time, and after the predetermined time has elapsed, the drain valve (12) and the water supply valve (23) are closed to rinse. The run is terminated, thus completing one wash cycle.

During this rinsing operation, the foaming chamber (3) in which the rinse water flows down in the detergent liquid chamber (5) containing the detergent liquid holder (13).
Since it is located on the side of the product, it does not come into direct contact with rinsing water, leftovers, etc. and maintains a clear state at all times. It is possible to continue to deliver the wash foam from the beginning.

In addition, the detergent solution holder (13) is only in a wet state and is not affected by the detergent fluid head, so the fan
(7) Light load at startup.

Thus, FIG. 6 shows the main part of another embodiment of the present invention. As shown in FIG. 6, the detergent liquid chamber (5) is arranged in a ring shape around the middle part of the side wall of the foaming chamber (3). At the same time, several holes (6) are distributed and opened on the corresponding vertical side walls to form a foam chamber.
It may have a structure in which the donut-shaped detergent liquid holder (13) is housed in (3).

The dishwasher has been described above as an example, but the present invention is not limited to the dishwasher described above, and various modifications can be made without departing from the scope of the invention, and other articles such as machine parts. The same effect can be achieved by applying it to cleaning of the like.

(Effects of the Invention) Next, the effects of the present invention will be described below.

The detergent liquid chamber (5) is located outside the side wall of the foaming chamber (3) through which foreign substances such as rinse water, residual food and dirt adhering to the cleaning object pass.
Since the detergent liquid chamber (5) itself and the fresh cleaning foam generated in the chamber (5) are not contaminated because they do not come into contact with the leftover food and foreign substances, all the foam generated at the same time as the cleaning is started. The cleaning efficiency is improved because it can be used.

Further, it is not necessary to discharge the residual foods and foreign substances in each cleaning cycle, and the loss time is reduced.

Furthermore, since there is no detergent head in the air flow path of the fan (7) and the load is light, the capacity of the fan can be reduced.

The present invention also has a problem that the detergent liquid holder (13) is replenished with the detergent liquid with a slight time lag after the fan (7) is operated, so that excessive liquid supply causes dripping and defective foaming. There is no.
