Description

The present invention relates to a water supply device for a washing machine pour water rectified in the washing or during rinsing in washing tub.

  Conventionally, a water supply device of a washing machine is generally provided with a water injection device for injecting water into a washing and dehydrating tub from an outlet having a detergent charging lid that can be opened and closed, and a rib for diffusing the water injection flow is provided at the outlet. (See, for example, Patent Document 1).

  FIGS. 4-6 shows the water supply apparatus of the conventional washing machine, and demonstrates the structure below. As shown in FIG. 4, the water receiving tub 1 includes a washing / dehydrating tub 3 in which a pulsator 2 is rotatably disposed at the bottom, and is suspended from an outer frame 5 by a suspension bar 4. An upper exterior body 6 is attached to the upper part of the outer frame 5, and a cloth insertion port 7 is formed at a substantially central portion of the upper exterior body 6 and covered with a lid 8.

  A water injection device 11 communicating with the water supply valve 10 is attached to the rear portion of the upper exterior body 6. As shown in the exploded perspective view of FIG. 5, the water injection device 11 is connected to the water supply valve 10 in a watertight manner by a water injection hose 9 made of a flexible rubber or plastic material, and can be easily washed. Water is poured into the washing and dewatering tub 3 from the outlet 12 when the water is excessively passed, and a detergent charging lid 15 is attached, and as shown in the cross-sectional view of the main part in FIG. As shown in FIG.

  When the detergent charging lid 15 is closed, water is poured into the washing and dehydrating tub 3 from the outlet 12 at the lower end of the detergent charging lid 15, and when the detergent charging lid 15 is open, the detergent is poured onto the detergent charging lid 15. Thus, water is poured into the washing and dewatering tank 3 while dissolving the detergent together with the washing water at the time of washing.

When the predetermined water level is reached, the pulsator 2 is driven to perform washing. After washing is finished and the high-concentration washing liquid is drained, in the rinsing process, water is accumulated in the water receiving tub 1, and the detergent components on the clothes are diffused and diluted in the rinsing water.

  However, in such a conventional configuration, since the water supply valve 10 and the water supply device 11 are connected by the connection hose 9, high water pressure from the water supply valve 10 is directly applied to the connection hose 9. Depending on the variation of the material and the aging of the material, there may be a problem such as coming off and leaking water.

  Further, when the detergent charging lid 15 is opened, the detergent is poured onto the detergent charging lid 15, and water is poured into the washing and dehydrating tub 3 while dissolving the detergent together with the washing water, it is affected by the tap water pressure used. For example, when the amount of water supply is small, water may not be poured over the entire surface of the detergent charging lid 15, and there is a problem that the remaining detergent dissolved on the detergent charging lid 15 is generated.

  On the other hand, when the flow rate is large, there is a problem in that the aesthetics of the user is impaired due to a shift in water supply to the washing tub due to the momentum of the water flow.

  In addition, when a bus pump (not shown) for using the remaining water of the bath water is mounted, the mechanism that fills the priming water of the bus pump and the water supplied from the bus pump are the same as the water supplied from the water supply valve 10. In addition, a separate mechanism for rectifying and throwing it into the washing and dehydrating tub so as not to be rebounded was necessary.

  The present invention solves the above-mentioned problem, and even if a high water pressure flows from the water supply valve, the watertight connection structure between the water supply valve and the water injection device is not likely to come off, and is related to the amount of water supply. The purpose is to obtain a water supply device for a washing machine in which a bath pump can be mounted, as well as to eliminate the dissolution residue of the input detergent and the misalignment of the water supply.
