Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine having a foam washing function and a foam washing function incorporated therein, or a bubble generating apparatus.

[0002]

2. Description of the Related Art In a conventional washing machine, washing is performed by agitating a pulsator 18 at the bottom of a washing tub 17 to dehydrate the washing liquid water, and then the laundry is put into the washing tub 17 to inject water to finish the water rinsing and dehydrate again. And had completed the washing.

[0003]

Conventionally, conventionally, washing and water rinsing are forcibly washed by rotating and stirring the pulsator 18 at the bottom, but the laundry is entangled with each other to cause damage to the fabric, and twisting and entanglement are repeated and water flow is repeated. I was just looking for that effect. Since the pulsator 18 forcibly stirs and cleans the cloth, complete cleaning of the inside of the cloth requires a long time of washing and cleaning, and a large amount of detergent and rinsing water is also used, which causes environmental drainage of domestic wastewater.

[0004]

According to the present invention, in addition to the conventional washing method, in the case of washing, a method of ejecting bubbles 8 from the bottom portion by an air pump 19 or the like at the same time as the rotation of the pulsator 18 and a pump 22 or the like are used to wash the washing tub 17. By circulating the cleaning liquid and ejecting it through the bubble generator B of the present invention, the bubble jet injection 9 enhances the cleaning ability and enables soft washing with less cloth damage and promotes its effect. In the case of water rinsing after dehydration, conventionally, rinsing water was injected to stir and recirculate, but when both the water injection port and the drain port are located at the upper part, it is effective to rinse water because the water injection port and the drain port are close to each other. However, it was unreasonable because some of the wastewater immediately drained. Even when the water was poured from the bottom, the pulsator 18 was only washed because the water was simply poured.

According to the present invention, rinsing water and air bubbles are simultaneously ejected from the bottom of the washing tub 17 so that irrational points can be eliminated and effective rinsing can be performed in the case of rinsing, and the conventional pulsator 18 is washed by forced stirring. Not only this, new water and air bubbles are spouted from the bottom and circulated and drained from the upper part, so that soft washing with less cloth damage is promoted as in the above-mentioned air bubble washing. The purpose of this washing method can be achieved by incorporating a bubble generator B and a pump 22 for circulating the washing liquid in the washing machine 16 and switching them according to the intended use. In some cases, only air bubbles are generated by the air pump 19.

[0006] As described above, in order to save labor and simplify the washing and washing method, the bubble generator B according to claim 2 is incorporated in the washing machine 16 to be produced in the future. It is possible to equip it with, and it was prepared separately in the washing machine currently used.

By fixing the bubble generator B of FIG. 2 to the inner wall of the washing tub 17, the purpose can be easily achieved.

[0007]

Whether the laundry is washed or rinsed with water, the pulsator 18 is forcibly washed by rotation of the pulsator 18, and since only the vertical circulating water flow is operated, the laundry is rotated and twisted and entangled. It was impossible to wash the inside of the fiber, and a large amount of detergent and time were required for complete washing. The same was true for rinsing and a large amount of water was required. In order to solve these problems, bubbles are jetted from the bottom part with stirring. As a natural phenomenon, these bubbles rise to the top and adhere to the fabric, and the pulsator 1
As it is stirred and refluxed by 8, it penetrates and penetrates into the fiber inner layer,
Since it can extract the washing liquid and dirt, it can be sufficiently washed by the circulation by the soft rotation. In this way, complicated stirring movements such as lateral stirring water flow due to rotation of the pulsator and rising water flow due to bubbles ejected from the bottom can be performed, so the effect on the fabric is soft, but great cleaning power is exerted. Yes Detergent, rinse water, etc. can be reduced and the time can be shortened.

As described above, not only the cleaning effect due to the rotation of the pulsator 18 but also a great effect can be obtained by injecting bubbles. Particularly, in rinsing, rinsing water is ejected from the bottom part at the same time as bubbles. As a result, it is possible to obtain a large amount of washing with the same softness as above. Needless to say that it can save the rinsing water and shorten the time, and when rinsing water is poured from the top as in the conventional case, it is close to the top drain Since it was an irrational rinse method that a part of it was drained directly, this can be rationalized. The above-described bubble generating device of the present invention can be incorporated in a washing machine manufactured from now on, but it is also necessary for a washing machine currently used.

By fixing the bubble generating device B of the present invention of FIG. 2 in the washing tub 17, the same objective effect can be easily obtained.

Next, the bubble generating apparatus of the present invention will be described. The process of rinsing with water will be explained first, so it will be understood from now on. However, this explanation is for the case where the washing machine is used in the washing tub of the currently used washing machine. The water pipe 1 that connects the water pipe 1 to the hose 30 from the water tap 31
The outlet is made narrower and narrower than the inner diameter of the water passage 1 to form a nozzle shape. It becomes possible to obtain a jetting force due to a larger water pressure when passing water. The water cylinder 1 is housed inside the water cylinder 4 having an inner diameter larger than the outer diameter of the water cylinder 1. Each of the water cylinders 1 is held so that a gap is maintained between the cylinders for air supply. This combined set of cylinders is fixed to the side wall in the washing tub 17, but at this time, the upper end port of the air supply cylinder 4 is projected and fixed upward from the water level in the tub so that water does not flow into the cylinder 4. Like The lower end jet port 5 is fixed by opening at a position close to the bottom. Water bottle 1
The nozzle injection port 3 is located above the lower end port of the through cylinder 4.

When the rinsing water 10 is injected into the water pipe 1 with the above structure, the water of high water pressure is jetted vigorously from the nozzle 2. This injection is ejected in the middle of the through cylinder 4 inserted in the water. At this time, water may have entered the through cylinder 4 beyond the nozzle 2, but at the same time as the injection, the water in the cylinder is ejected and extruded, and the nozzle 2 is exposed and the ejected through cylinder is ejected. 4 Rinse water and air are mixed from the lower opening 5 and jetted into the tank. The principle is that the water level at the nozzle position and the jetting force due to the water pressure greater than the water pressure cause a vacuum state in the nozzle ejection area 2 in the cylinder 4 to eject the water in the cylinder 4 in the suction / injection direction, and then to the water pressure in the cylinder 4 Then, the air is sucked and ejected. At this time, air is mixed with the water, and the water pressure is simultaneously breached and jetted out of the cylinder. At this time, if water enters the through cylinder 4 from above or the nozzle 2 projects below the through cylinder 4, this jet injection does not operate and bubbles cannot be generated. Even if the position is above the water level in the washing tub 17, similar effects can be obtained if the injected water pressure is large.

Therefore, the principle is the same whether it is built in a washing machine or fixed in a tub, and the strength of bubbles is naturally changed depending on the water pressure injected into the water pipe 1 and the position of the depth of the nozzle 2. That is. Next, when the washing liquid in the washing tub 17 is used for washing, the same as the above, the washing liquid is absorbed and circulated by the pump 22 or the like to be injected into the water pipe 1 and ejected from the nozzle 2 to generate air bubbles and air. It can be mixed and jetted together into the tank 17.

[0012]

[Example 1]

In FIG. 1, a bubble generator B of the present invention will be described. First, the structure and function of the bubble generator of this device will be described to explain the case of water rinsing. This device is premised on the use of pressurized water having a certain water pressure, such as tap water.

As shown in FIG. 1, the water pipe 1 is composed of two pipes, a water pipe 1 and a water pipe 4, and the water pipe 1 is connected to a water pipe. The injection port of this water passage 1 has a single-ended or perforated nozzle 2 shape with a narrowed tip, and is positioned below the lower water level 13. This water bottle 1
Is housed in the through cylinder 4 and the upper and middle portions with respect to the water cylinder 1 are maintained by the perforated cap 6 and the perforated support piece 7 to maintain a ventilation gap. The through cylinder 4 projects above the upper water level 12 to prevent water from entering, and the lower portion is lower than the lower water level 13 and the nozzle 2
Position the jet port 5 below

Under the above conditions, the valve 11 is opened to allow the water supply 10 to pass. The water passes through the water passage cylinder 1 and is jetted from the nozzle 2, but becomes jet pressure water higher than the water pressure to be supplied, and is jetted into the passage cylinder 4. At this time, the nozzle 2 is installed inside the through cylinder 4.
If the water pressure in the cylinder 4 is suctioned or discharged by the jet ejection force that is further ejected, and if the water pressure at the ejection port 5 is stronger, the air is sucked from the through cylinder 4 and mixed with the air.
And is vigorously and strongly ejected into the rinsing tank 17,
Even if the nozzle 2 is located above the water level 13, the same effect can be obtained, but it depends on the water pressure.

This device is used by being incorporated in a washing machine, but a bubble generating device B which is separately manufactured in the currently used washing machine.

[Fig. 2] The same effect can be easily used by mounting. This method is also used for washing. That is, instead of tap water, a washing liquid is pumped up from the washing tub 17 and connected to the water passage 1 to generate bubbles with the same effect, and a washing effect can be obtained.

[0015]

Example 2

FIG. 2 is intended to be used for rinsing water more easily than a tap when using the apparatus described in FIG. 1 in a washing machine currently in use.

As shown in FIG. 2, the hose 30 is connected to the upper end of the water pipe 1. The other hose 30

As shown in FIG. 3, the hose 30 is slanted as shown by the solid line by pushing a cut or U-shape in the longitudinal direction as shown in FIG.
As it is hooked on the lower jaw of the faucet, it returns to the vertical position as shown by the broken line, and by returning it, the faucet can be easily inserted into the hose. The water tap 31 and the hose 30 can be easily and strongly connected by the tightening force of the elastic ring or the metal fitting 32. On the contrary, when detaching, the metal fitting 32 is removed and the hose 30 is inclined as indicated by the solid line, so that the hose 30 can be easily removed. next

As shown in FIG. 2, the bubble generator B is fixed to the inner wall of the washing tub 17 by the suction plate 14 and the attachment belt 15 to complete the attachment.

In this case

As shown in Fig. 1, pay attention to the mounting position and height of the upper and lower water levels. Again this

2 is used for rinsing with water, and for the purpose of washing, separate pumping pump 2 is used instead of tap water.
The same purpose can be satisfied by sucking the wash water in the tank 17 and connecting the water to the water pipe 1 to supply water by the method 2 described above.
