Description

Device for changing flow path in electrical washing machine}

The present invention relates to a flow path switching device provided in the washing machine, and more particularly to a structure of the flow path switching device of the washing machine to improve the circulation and drainage structure of the wash water.

In general, a washing machine is a device that peels contaminants from laundry by applying energy such as impact to laundry, and is classified into a pulsator type washing machine and a drum type washing machine according to a method of applying energy to the laundry.

That is, the laundry is impacted by the pulsator, or the laundry is dropped by rotating the drum to impact the laundry. And the action of the detergent is added to this is done washing.

On the other hand, the above-mentioned washing machines are installed in a veranda or toilet, which is not easily seen by a person, which is a specific place, and where damage from vibration and noise generated by the rotation of the washing tank is less.

That is, the pulsator type washing machine has an upright structure that can satisfy the washing capacity only when the pulsator type washing machine has a certain height, and has a structure in which a washing tank is provided in a state perpendicular to the ground so that laundry is put into the upper part. Is taking.

On the other hand, the drum type washing machine has a relatively low level horizontal structure, and has a structure in which an inner tank is placed in a state in which a washing tank is placed with an acute inclination angle between the ground and the ground. Accordingly, the washing capacity is smaller than that of the pulsator washing machine, and since the inner tank is in a horizontal state, the rotational force of the driving motor is transmitted to one end thereof.

Although there are structural differences as described above, a washing machine generally uses a series of washing, rinsing, dehydration, drying, etc. to remove contaminants on clothes, bedding, etc. (hereinafter referred to as laundry) contained in a drum using water and detergent. The device for washing laundry through the process of.

A conventional washing machine is composed of a casing forming the exterior, an outer tub fixedly installed in the casing, an inner tub rotatably installed in the outer tub, and a motor for transmitting rotational force to the inner tub, and a washing unit and a washing unit for controlling the washing process. It is equipped with a water supply device and a drainage device for supplying and draining the water required for the supply.

In the washing process of the washing machine, the laundry is washed by using the emulsification of the detergent and the friction of the water flow due to the rotation of the washing blade and the impact of the washing blade. The washing process consists of a washing process that removes contaminants from clothes using the action of detergent and water, a rinsing process that rinses the laundry several times after washing, and finally a dehydration process that removes the moisture of the laundry using centrifugal force. Proceed through The washing process, the rinsing process and the dehydration process are automatically performed by a preset program.

Between these processes, it may be advantageous to supply new water by using a hose to the washing machine, and to reuse the washing process or drained washing water, and in some cases, part of the water drained and drained at the same time during the washing process. By supplying the back into the washing machine, washing can be performed more efficiently.

In general, a washing machine having such a circulation structure includes a circulation pump and a circulation device for circulating the wash water in addition to the drain pump for draining the wash water, and thus, the internal structure becomes complicated and the manufacturing cost increases. .

The outflow guide 127 ′ combines with the inner diameter of the connect packing 131 to prevent leakage of the washing water flowing out of the flow path.

Figure 5 is a longitudinal cross-sectional view of the flow path switching device of the washing machine according to an embodiment of the present invention.

Looking at the drawings, the case 120 is mounted inside the housing 110 composed of the main housing 111 and the upper housing 112. When the rotating shaft 124 formed on the upper case 121 projects through the through hole 106 formed in the upper housing 112 to the outside, the rotation force by a predetermined angle according to the command of the controller (not shown). It is connected to a motor (not shown) that applies a.

On the other hand, the inlet guide 101 'of the lower case 122 is coupled to communicate with the inlet 101, the pressure packing 134 is interposed.

The connect packing 131 between any one of the drain hole 102, the circulation hole 103, and the bubble hole 104 formed on the side of the housing 110 and the connector 125 coupled to the case 120. ), The elastic member 132 and the bushing 133 is shown in communication with the intervening state.

In detail, the washing water flowing in the direction of the arrow in the lower portion of the drawing is a rotational force of the motor (not shown) is applied to the rotating shaft 124 according to a control command transmitted by the controller (not shown) to a predetermined angle by a predetermined angle. It rotates in the direction to communicate the inlet guide formed in the connector 125 toward the bubble sphere 104 to let the wash water out.

At this time, the pressure packing 134 is lifted toward the inlet guide 101 'by the pressure of the wash water flowing into the inlet 101, and thus, between the inlet 101 and the inlet guide 101'. Naturally sealed, it will be waterproof.

In addition, on the outer surface of the connector 125 communicating with the foam ball 104, the connector packing 131 in contact with the connector 125 is the connector 125 by the elastic force of the elastic member 132 By being pressed while being pressed toward the side serves to prevent leakage between the surfaces of the wash water discharged through the outlet guide 127 is in contact.
