Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to washing machines, and particularly to a water injection system that can quickly remove all detergent foam and detergent scum attached to the walls of the washing tub in a two-tub washing machine.

In conventional two-tub washing machines, when injecting water into the washing tub, as shown in Figure 4, a material such as a "hechi-kake" or porous foam is placed inside the water-injection box, and this part is used to inject water into the washing tub. It absorbs and rectifies the air that gets drawn in with tap water, making it look like °
The structure was such that water was injected into the washing tub from a pipe.Therefore, when doing Susuki work, there is less air being drawn in, so there is less need to raise 2m, so rinsing can be done quickly. , and it was easy to visually determine whether the rinsing was completed or not. In other words, it was difficult to determine whether the foam was caused by detergent or by air being trapped, but with the above configuration, the bubbles were only caused by the detergent. Therefore, it is easy to judge. However, after washing is completed and before moving on to rinsing, the washing g is drained, but in this case, foam and scum from the washing liquid adhere to the tank wall.

In order to remove the foam and debris, the conventional method was to remove the water supply hose from the water supply port one by one, crush the end of the hose, and spray water like a shower to remove the foam and debris.However, this conventional method This method had the drawback that it was cumbersome and time-consuming because the water supply hose had to be completely removed each time.

The purpose of the present invention is to solve the above-mentioned drawbacks of the prior art. To provide a washing machine equipped with a device that can quickly and easily remove detergent foam and other detergent foam adhering to a tub wall after washing is completed. In order to achieve all of these objects, the present invention provides a shower water injection device and an anti-foaming water injection device integrally installed in a water supply box, a water supply guide in the water supply box as a switching valve, and furthermore, the shower water injection device A defoaming water inlet is provided in the shower guide, and the water supply can be easily switched between defoaming water injection and shower water injection by simply sliding the water supply guide.

The system was designed to make it movable. The above is the configuration of the washing machine of this embodiment.

The action will be explained in detail below. First, the water must be drained after washing, but at this time, bubbles and detergent scum remaining in the detergent solution adhere to the inner wall of the washing tub 2.

Conventionally, in such a case, the hose 29 was removed from the water supply port 27 and the detergent scum etc. that had adhered to it were sprayed directly from the hose to be removed. They used to scoop up the liquid by hand and pour it over the detergent residue. The present invention was conceived in view of these points,
A defoaming water injection device 31 and a shower water injection device 32 are installed in a water injection box 30, and a case 33 that constitutes this box 30 is installed.
The water injection device 31- or 32 can be switched to the respective water injection device 31- or 32 by means of a water supply guide 39 slidably housed inside. Therefore, when filling water normally, that is, when storing water in the washing tub 2 (/i''l), the water supply guide 39 in the case 33 is stopped in the state shown in FIGS. 3 and 4, and the water is turned off. The other shower water inlet 37, which makes the foam water injection guide hole 42 and the anti-foam water inlet 34 face each other, that is, opens the anti-foam water injection device 31, is automatically closed.
When the faucet 28 is opened, water passes through the hose 29 and the water supply port 27, and is injected into the defoaming water inlet 34, r, rinse, and (frost tank 2). When passing through the porous network 41, the air in the water is separated, impurities in the water are also removed, and the water is rectified to form a smooth laminar flow.Now, after the formation of a layer of water is completed, The detergent in the washing tub 2 is drained, but as the drainage progresses, detergent scum etc. adhere to the inner wall of the washing tub 2.This adhesion becomes impurities during the next rinsing process, so it must be removed in advance. The next step, rinsing, will be more effective.

In this case, by using the water injection device of the present invention, detergent scum and scum can be easily removed after draining.In other words, as shown in FIGS. 5 and 6, the water supply guide 39 slide in the direction of arrow
After 50 flexible hoses, we reached the water supply guide 39.
Furthermore, the water is discharged radially (indicated by the two-dot chain line in FIG. 1) onto the wall surface of the washing tub 2 by the outer surface 36 of the shower guide 35 through the shower guide hole 43 and the shower inlet 37. It is a product that can easily and quickly remove detergent scum, etc. that remains or has accumulated on the product. Therefore, there is no need to perform operations such as pulling out the 29-metal hose and dropping the hose as in the past. In this case, switching between the anti-foaming water inlet [] 34 and the shower water inlet 37 is performed using the water supply guide inside the case 33. 39 can be easily switched by simply sliding it in the direction of the arrow XvX'.

- As mentioned above, the water filling box 3o of this configuration is provided with 35 approximately truncated conical shower guides as shown in the figure.
And the water is in a state of flowing on this outer surface 36/
It works as a water injection device 32.

Furthermore, the percentage characteristic of this configuration is that the defoaming water inlet 34 is completely provided inside the shower guide 35, and the relationship between the area A of the defoaming water inlet 34 and the area B of the shower water inlet 37 is at least A≦
In order to achieve B, the /Yowa water inlet 37 is arranged on the external force of the antifoaming water inlet 34, and the water inlet 34.3 is placed like this.
A defoaming water injection kite hole 42 and a 7-water kite hole 43 are provided oppositely to the 7. (When using it as a shower sweat device 32, it is sufficient to do as described above. When using it as an antifoaming water injection device 31, it is necessary to do as shown in Fig. 1 and Fig. 4.) In addition, when taking a shower, the sludge and antifoaming water 1134 is shielded with a lid-shaped part 45 provided inside the shower guide hole 43, and the water is automatically poured into the shower.
) The outer surface [fi] 36F of the j-id 35 is to be sprayed with water. Therefore, this shower water injection easily washes away impurities such as detergent scum and powder that have accumulated on the wall surface of the washing tub 2. By installing it almost on a solid axis, the entire circumference of the tank wall can be quickly cleaned.Furthermore, this shower water injection device 3
2 is installed above the washing tub 2 together with the defoaming water inlet 34, so it has features such as being able to easily press the water inlet state.

As explained above, according to the present invention, in a two-tub washing machine, detergent foam and scum attached to the tank wall after washing are finished.
etc., can be quickly removed with extremely simple operations.
