A rear end of the third hose connecting portion 73 is connected to a hose 88 connected to a service pipe, and a front end of the third hose connection portion 73 is a portion of the second hose connecting portion 74 protruding like a pipe so that one end of the inlet hose 82 is fitted thereto.
Moreover, the first [0045] hose connecting portion 78 protrudes like a pipe from a lower rear side of the detergent box 76 so that the other end of the inlet hose 82 is fitted thereto.
An operation of the water supply assembly of the drum type washing machine according to the present invention is explained as follows. [0046]
First of all, once the drum type washing machine operates to turn on the [0047] inlet valve 72, the water passes the inlet valve 72, inlet hose 82, detergent box 76, and inlet bellows 75 in turn via the external hose 88 and then flows in the tub 4 and the drum 6.
Since the second [0048] hose connecting portion 74 of the inlet valve 72 is disposed higher than the first hose connecting portion 78 of the detergent box 76, the water passing inside the inlet hose 82 enables to smoothly flow in the detergent box 76. Moreover, the water lingering in the inlet hose 82 naturally flows toward the first hose connecting portion 78 of the detergent box 76, thereby completely flowing into the detergent box 76.
Accordingly, the apparatus for water supply of the drum type washing machine according to the present invention has the following advantages or effects. [0049]
First of all, the first hose connecting portion of the inlet valve connected to one end of the inlet hose is disposed higher than the second hose connecting portion of the detergent box connected to the other end of the inlet hose. Hence, the water flowing inside the inlet hose is immediately supplied to the detergent box and fails to remain in the inlet hose, whereby the inlet hose is prevented from being frozen to breakage. [0050]
