Description

Drum Washing Machine

The present invention relates to a drum type washing machine, and more particularly, a casing, a tub accommodated in the casing along a horizontal axis of the casing, and having a water inlet for inflow of washing water, and coupled to an inner side of the tub. The present invention relates to a drum type washing machine having a flap valve that opens the water supply port when the washing water is introduced through the water supply port and elastically blocks the water supply port when the washing water is not introduced.

Figure 4 is an exploded perspective view of a conventional drum type washing machine, Figure 5 is a cutaway exploded perspective view showing the flap valve region of Figure 4, Figure 6 is a cross-sectional view of the combined state of the flap valve of FIG. As shown in these figures, the washing machine has a rectangular tubular shape that is upwardly opened and a casing 101 having a front opening 103 for entering and exiting laundry on its front surface, and a plate-shaped saw coupled to the upper end of the casing 101. It has a cover 105 and a door 107 coupled to pivotally open and close the front opening 103 of the casing 101.

In the casing 101, a tub 115 having a drum shape with one side open is provided. A spring member 117 having one end coupled to the upper opening of the casing 101 is coupled to the upper region of the tub 115, and a plurality of shock absorbers 118 to buffer the tub 115 in the lower region. Is combined.

The tub 115 has a rotating shaft 123 disposed along the front and rear directions of the casing 101, and a spin basket 119 having a cylindrical shape having one side opened therein is rotatable. The spin basket 119 is formed with a plurality of dehydration holes 121 penetrating along the circumferential surface, and the rotation shaft 123 extends outwardly on the opening opposite side of the spin basket 119. The rotating shaft 123 is installed to pass through the tub 115, and the driven pulley 125 is coupled to the exposed side end.

A drive motor 127 for forward and reverse driving of the spin basket 119 is coupled to the lower region of the tub 115, and a drive pulley 129 is provided on the rotation shaft of the drive motor 127. The driving pulley 129 and the driven pulley 125 are connected to each other by the belt 131 so as to be rotatable along the same direction.

Meanwhile, an operation panel 111 having a plurality of operation buttons 113 is provided in the upper front region of the casing 101 so as to select a washing course, and a detergent container containing detergent on one side of the operation panel 111. Detergent container 110 is provided to accommodate the (109). In the upper region of the detergent container accommodating part 110, a water supply part 112 is provided to spray the washing water with the injection hole downwardly opened into the detergent accommodating space of the plurality of compartments of the detergent container 109.

In the rear region of the casing 101 is provided a connection portion 114 to which a water supply pipe (not shown) for supplying water from the outside is connected, and a water supply valve 116 is provided at the connection portion 114 to control the flow of washing water. Are combined. Supply pipe 135 is coupled to the outlet side of the water supply valve 116, the other end of each supply pipe 135 is connected to the water supply unit 112, respectively. In the lower region of the detergent container accommodating part 110, a water collecting part 137 is formed to temporarily accommodate the washing water falling together with the detergent from each detergent accommodating area of the detergent container 109. The lower end of the collecting portion 137 is coupled to the connecting pipe 139, one end of which is connected to the tub 115.

A through hole 141 is formed in the front end of the tub 115 so as to pass through the plate surface so that the connection pipe 139 can be coupled, and the boss protruding from the plate surface in the inner through hole 141 region of the tub 115. The part 143 is formed. The boss portion 143 opens the water inlet 140 when water is supplied to the wash water, and a flap valve 147 that elastically blocks the water inlet 140 when water is finished is fixed by the screw 145.

By this configuration, when the laundry is accommodated in the spin basket 119 and the washing course is selected, the controller (not shown) controls the water supply valve 116 so that the washing water is supplied into the tub 115. The water supply valve 116 is opened and the wash water introduced into the water supply unit 112 is injected into the detergent receiving area and introduced into the tub 115 through the connection pipe 139 together with the detergent. At this time, the flap valve 147 is rotated so that the water inlet 140 is opened by the inflow force of the wash water, and the water supply 140 is shut off with its elastic force at the same time as the water supply of the wash water ends.

By the way, in such a conventional drum type washing machine, as the use period elapses, the pressure according to the water supply acts repeatedly on the flap valve, thereby reducing the elastic force of the flap valve. Therefore, when the flap valve does not properly block the water inlet, there is a problem that the foam formed by the detergent during the washing rises through the connecting pipe. In addition, in the case of having a drying function, there is a fear that air in the tub heated during drying may flow out of the tub through the connecting pipe.

Accordingly, an object of the present invention is to provide a drum type washing machine having a flap valve that can open and close a water supply port formed in a tub smoothly.
