Foam and steam backflow prevention device of drum washing machine {DRUM TYPE WASHING MACHINE}

The present invention relates to a drum washing machine. In particular, the opening and closing member on the flow path inside the water supply bellows hose connecting the detergent container and the tub to supply the tub with washing water supplied to the drum washing machine water supply valve and mixed with the detergent in the detergent container. When the washing member is supplied to the tub through the water supply bellows hose by the opening and closing member to open the flow path of the water supply bellows hose and excessively generated in the tub when washing the detergent and boils generated during washing The present invention relates to a foam and steam backflow prevention device of a drum washing machine, when the steam to be flowed back to the water supply bellows hose to block the flow path of the water supply bellows hose by the pressure generated by the rotation of the drum.

The water supply configuration of the conventional drum washing machine is shown in FIG.

The drum washing machine (1) is a water supply valve (3) mounted to the cabinet (2) to receive the external washing water,

A water supply hose 4 having one end connected to the water supply valve 3 for carrying the wash water supplied through the water supply valve 3;

A detergent container 5 connected to the other end of the water supply hose 4 and installed in the cabinet 2 to receive washing water supplied to the water supply valve 3 and mix with the detergent;

In order to supply the wash water mixed with the detergent in the detergent container 5 into the tub 8, the water supply bellows hose 6 is connected to the detergent container 5 and the tub 8.

2 and 3 are a perspective view and a cross-sectional view showing the water supply bellows hose, and the water supply bellow to retain the wash water to prevent bubbles and vapors from flowing back into the detergent container 5 through the water supply bellows hose 6. The wood hose (6) is provided with a U-trap (7).

Referring to the effects of the conventional configuration as described above are as follows.

First, during the water supply stroke of the drum washing machine 1, the wash water is supplied through the water supply valve 3 mounted on the cabinet 2 and supplied to the detergent container 5 through the water supply hose 4.

Since the wash water supplied to the detergent container 5 is supplied in a shower method, the washing water and the detergent in the detergent container 5 are evenly mixed.

In addition, the wash water mixed with the detergent in the detergent container (5) is a water supply bellows hose

It is supplied to the tub 8 through 6.

Therefore, when a certain amount of washing water is supplied to the tub 8, the drum in the tub 8 rotates forward and backward by the driving of the motor and moves to the washing stroke.

In addition, when the detergent is excessively added during the washing process as described above, a large amount of foam is generated in the tub 8 and steam is generated during washing, and the foam and steam are supplied to the water supply bellows. In order to prevent backflow into the detergent container 5 through the wood hose 6, the water supply bellows hose 6 is conventionally bent to form the U-trap 7.

That is, the inside of the U-trap 7 is supplied with water as shown in Fig. 3, and the remaining wash water maintains the water level of H1.

Therefore, the foam and steam flowing back to the water supply bellows hose 6 are prevented from flowing back to the detergent container 5 by the washing water remaining in the U-trap 7.

However, the drum washing machine 1 always generates natural vibrations during washing.

That is, as the washing water of the U-trap 7 drops into the tub 8 little by little by the vibration of the drum washing machine 1, the level of the U-trap 7 rises from the H1 level to the H2 level in FIG. Will fall.

Thus, bubbles and vapors generated in the tub 8 flow back into the detergent container 5 through the space portion generated due to the lowered water level difference of the U-trap 7.

In addition, the foam flowing back as described above flows to the front of the drum washing machine 1, thereby corroding the cabinet cover, which results in shortening the life of the washing machine.

In addition, the foam that flows down the front of the drum washing machine (1) falls to the floor of the room may cause damage to the user's injury.

The life of the water supply bellows hose 6 is also shortened by the detergent remaining in the water supply bellows hose 6.

In addition, the water supply bellows hose 6 has a problem in that the inlet and the outlet are formed at different angles as shown in FIG.

In addition, the user may be burned by the steam heat flowing backward and leaking to the outside.

The present invention to solve and solve the above conventional problems,

It prevents the cabinet cover from corroding by foam leakage by preventing the foam generated during washing administration or steam generated during washing from flowing back to the front of the washing machine through the water supply bellows hose and flowing down to the front of the washing machine. This prevents contaminants from being contaminated and reduces the risk of burns due to steam heat and extends the life of the washing machine.

In order to achieve the above object, the present invention,

An opening and closing member is provided on the flow path inside the water supply bellows hose of the drum washing machine. When the washing water in the detergent container is supplied to the tub through the water supply bellows hose by the opening and closing member, the water supply bellows hose is opened and the detergent is released. Too much foam in the tub during use and steam boils during washing is prevented by the pressure generated by the rotation of the drum when the flow of the water supply bellows hose flows back to the water supply bellows hose. Can be achieved.

The tub 105 is supplied to the tub 105 through 111, and the wash water supplied to the water supply bellows hose 111 passes through the opening / closing member 113, that is, the check valve 133.

That is, the check valve 133 opens the flow path 112 by its own weight as shown by the virtual line of FIG.

Therefore, when the wash water is supplied to the flow path 112 of the water supply bellows hose 111, the wash water passes through the wash water, thereby supplying a predetermined amount of the wash water to the tub 105.

And, if the detergent is excessively injected during the above laundry administration tub

(105) When a lot of foam is generated inside the boil and wash the steam is generated, the foam and steam is discharged through the water supply bellows hose 111 by the pressure generated by the rotation of the drum You will be tempered to be.

However, the check valve 133 coupled to the flow path 112 of the feedwater bellows hose 111 of the present invention has flow path 112 as indicated by the solid line in FIG. 8 by the pressure generated by the rotation of the drum. Because the state is blocking the tub does not pass through the passage 112

It remains in (105).

In addition, the steam is discharged to the outside only through the normal passage, that is, the steam discharge passage, so that the user may not be burned by the abnormally leaking steam heat.

In addition, the water supply bellows hose 111 is prevented from being damaged by the vibration generated in the washing machine 101 by the buffer unit 114 formed in the water supply bellows hose 111.

In addition, since the water supply bellows hose 111 is provided on the flow path 112 in a straight line, washing water and bubbles do not remain in the water supply bellows hose 111, and thus the water supply bellows hose 111 is provided. It is possible to extend the life of the product.

In addition, when the water supply bellows hose 111 formed in the straight shape is inserted into the tub 105, the assembly is simply completed, so that good assembly performance can be obtained.
