Description

  The present invention relates to a powder detergent liquid mixing device and a washing machine including the powder detergent liquid mixing device.

  For example, in a laundry shop such as a cleaning shop, there is a demand for using a powder detergent that is less expensive than a liquid detergent, but it is difficult to automatically supply the powder detergent to the washing tub.

  Therefore, in the prior art, there is a washing machine equipped with the powder detergent liquid mixing device (hereinafter, a conventional example) illustrated in FIG. 7 that mixes the powder detergent and liquid (water) in advance before supplying the powder detergent to the washing tub. Proposed.

  As shown in FIG. 7, this conventional example is provided with an introduction part 33 for introducing a liquid 50 into a bottomed cylindrical main body 32 provided with a powder detergent introduction part 31 at the upper part and a discharge part 34 at the lower part. The liquid 50 introduced into the main body 32 from the introduction part 33 is mixed with the powder detergent 51 introduced into the main body 32 from the powder detergent introduction part 31 to become a mixed liquid 50 ′, and is guided to the inner surface of the main body 2 to generate a vortex. It is configured to flow down and be discharged from the discharge part 34.
