The present invention relates to a washing machine, and more particularly to a water supply device for a washing machine that can extend the length of the water supply hose.

1 is a cross-sectional view schematically showing the internal structure of a washing machine according to the prior art.

Referring to FIG. 1, the washing machine 1 supplies the air heated in the drying duct 2 into the tub 8. The heated air takes moisture out of the laundry and contains water, which in turn passes through a condensation duct (6) in communication with the drying duct (2) to meet with the condensate to lower the temperature, which turns the water into water and is drained through the outlet. .

In the conventional drum washing machine 1 having the above configuration, the length of the water supply hose for supplying the washing water to the washing machine 1 is determined, and the washing machine should always be installed near the tap water (water supply valve). Therefore, when there is no space to install a washing machine near the tap water (water supply valve), there is a problem that can not be installed washing machine. That is, the length of the water supply hose is changed according to the installation environment of the washing machine. Since the water supply hose is fixed in length, a problem arises in that the washing machine must be installed within the range of the length of the water supply hose.

In addition, when the washing machine is installed, the bending force is excessively acted on the connection portion of the water supply hose so that the water supply hose is separated from the coupling portion, or a gap is generated.

The present invention has been made to improve the above problems, and an object thereof is to provide a washing machine water supply device that can install a washing machine regardless of the installation space. In addition, an object of the present invention is to provide a water supply device for a washing machine that can reduce the bending force acting on the connection portion of the water supply hose.

2 and 3, the drum washing machine 100 is rotatably installed in the housing 111 forming an external shape, the tub 131 installed inside the housing 111, and the tub 131. And a drum 130 serving as a washing tank, a motor 140 installed at the rear to rotate the drum 130, and a drying device 120 for drying the laundry. In addition, the drum washing machine 100 is provided with a controller (not shown) for controlling the operation of each component, such as the motor 140, the drying apparatus 120.

Although not shown in the drawings, a plurality of holes are formed on the circumferential surface and the rear surface of the drum 130 to allow washing water and air to flow. Air inside the drum 130 flows into the space between the drum 130 and the tub 131 through the hole formed in the drum 130.

In the drum washing machine 100 of the present invention, after the end of the washing according to the repeated washing and dehydration stroke, the drying apparatus 120 sprays warm air into the drum 130 to dry the laundry. That is, the drying apparatus 120 heats and circulates air to dry the laundry inside the drum 130.

The drying apparatus 120 includes a heater 122 that is a heating device for heating air, a blower 121 for circulating air heated by the heater 122, and heated air is moved into the tub 131. It is provided with a drying duct 112 for providing a passage, and an air discharge portion 114 is installed to communicate with the inside of the tub 131. One end 123 of the drying duct 112 is formed to be opened so that heated air is moved into the tub 131. Here, one end 123 of the drying duct 112 may be installed so that the heated air is moved into the drum 130.

The heater 122 is installed inside the drying duct 112 between the blower 121 and the air inlet 123. As the heater 122, an electrothermal heater that generates heat by an electric current is used, and the temperature of the heater 122 is controlled by the thermistor 125. Blower 121 has a fan (not shown) that is rotated by a motor (not shown), and the fan is rotated to circulate the heated air.

On the other hand, it is necessary to remove moisture in the air to enable smooth drying. Condensate is generated when high temperature air contacts low temperature objects. The condenser 118 is disposed between the blower 121 and the tub 131 to remove moisture from the heated air by using the same principle as described above. That is, the condenser 118 flows the cooling water supplied through the water supply pipe 113 installed on the upper side of the drum washing machine 100 to the wall surface of the condensation duct 116 to relatively transfer the hot and humid air inside the condensation duct 116. The water vapor is condensed by contact with the wash water having a low temperature, thereby removing moisture inside the drum 130.

Although the water supply port 105 for supplying the washing water to the tub 131 and the water supply pipe 113 for supplying the cooling water to the condensation duct 116 are separately installed, the condensation duct 116 is provided using the water supply port 105. The cooling water can also be supplied directly. Since such a configuration is well known to those skilled in the art to which the present invention pertains, a detailed description of such a structure is omitted. That is, the drum washing machine 100 according to the present embodiment supplies heated air from the drying duct 112 to the tub 131 to dry the laundry, and the air discharged from the tub 131 passes through the condensation duct 116. It meets the coolant and condenses into water. The condensed water is discharged to the outside through the drain pipe 152 through the lower portion of the tub 131.

In addition, the drum washing machine 100 is provided with an air discharge unit 114 to discharge the air moistened during the drying process. One side 115a of the air discharge unit 114 is installed in communication with the tub 131 so that the air in the tub 131 is discharged to the outside, the other side 117a is installed in communication with the outside. The other end portion of the air discharge unit 114 is provided with an extension 117 installed with a fan (not shown) driven by a motor (not shown), and a filter 119 installed at the extension 117. .

Since the temperature of the air heated by the heater 122 can be measured stably and accurately at the air discharge portion 114 side, the air discharge portion 114 is provided with a temperature sensor (not shown) for detecting the temperature of the air. . Since the construction and operation of the temperature sensor are well known to those skilled in the art to which the present invention pertains, a detailed description thereof will be omitted.

2 to 4, the upper portion of the tub 131 is provided with a water supply port 105 through which the washing water is supplied from the water supply device 200 into the washing machine 100. The wash water supplied through the water inlet 105 is supplied into the tub 131 through the detergent container 106 in which detergent is stored.

Depending on the installation environment of the washing machine, the washing machine may be installed far from the water supply valve. In such an installation environment, the washing machine and the water supply valve cannot be connected using only one water supply hose.
