Abstract

The present invention relates to a drainage pump control apparatus for a washing machine, and the drain hose 40 is extended to discharge the pollutants to the outside to complete the washing process of the laundry, and is mounted on a predetermined portion in the drain hose 40 In the drain pump (30) for forcibly discharging contaminants to the outside, the air bell 21 and the air bell (21) to be filled with water to smoothly rise to a certain portion of one side of the drain hose 40, the air bell ( By configuring the water level sensor 20 that outputs a signal to detect the water level rising through 21) to allow the drain pump 30 to operate in a limited manner, by limiting the drain pump to operate only when the water level sensor detects the high water level. It reduces power consumption and the water rises easily through the air flow so that the water level sensor detects the water level so that the remaining water in the washing machine is detected to remove the noise caused by the remaining water. To provide an effect.

Description

Drainage pump control device of washing machine

The present invention relates to a drainage pump control device of a washing machine, and more particularly, to restrict the power consumption by operating the drainage pump from the output signal of the drainable water level sensor so as to reduce the power consumption by preventing excessive operation of the drainage pump. The present invention relates to a device for automatically limiting the forced drainage pump of a washing machine.

As shown in FIG. 1, a conventional drainage pump control apparatus for a washing machine includes a drain hose 4 extending to discharge contaminants to the outside to complete the washing process and wash the laundry, and a constant in the drain hose 4. A drain pump 3 for restraining contaminants to be discharged to the outside by being seated on the site and a level sensor 2 for outputting the water level of the predetermined water in the drain lake are locked and controlled are connected to each other.

The drainage pump control apparatus of the conventional washing machine configured as described above is discharged through the drainage lake connected to the outside of the washing machine 1 in order to discharge the contaminated foreign matters of the laundry to the washing machine 1 at this time. The drainage pump 3 seated on the four is operated and the contaminated water in the washing machine 1 flows into the drainage hose 4 according to the situation detected by the water level sensor 2 and is discarded out.

However, the drainage pump control apparatus of the conventional washing machine which acts as above should increase the power consumption since the drainage pump should always be operated at the time of drainage and dehydration, and the drainage pump operates even if the drainage pump does not have a certain amount of water. The water is not discharged into the hose and the water does not fall out to have a problem that the noise occurs due to the rocking.

The present invention has been devised to solve the above-mentioned conventional problems, and its purpose is to restrict the operation of the drain pump from the output signal of the drainable water level sensor so as to prevent excessive operation of the drain pump. To reduce the

The constitution of the present invention for achieving the above object is a drain hose extending to discharge the contaminants to the outside to complete the washing process of the laundry, and drained to the outside by being forced to discharge the contaminants to be seated in a predetermined portion in the drain hose In the drain pump to be, the air bell to allow the water to rise smoothly to a certain portion of one side of the drain hose and the water level rising through the air bell to detect the water level rising through the air bell is limited to operate It characterized in that it comprises a level sensor for outputting a signal.

Hereinafter, the technical configuration of the present invention by the accompanying drawings in detail.

Figure 2 is a schematic connection configuration of the drain pump control apparatus of the washing machine according to an embodiment of the present invention, Figure 3 is an enlarged view of a portion of Figure 3 of the drain pump control apparatus of the washing machine according to an embodiment of the present invention. to be.

The present invention is to operate the drain pump 30 in accordance with the signal detected the water level limited, in Figure 2 or 3, connected to a predetermined portion of the bottom of the washing machine to complete the washing process of the laundry after draining In the drain hose 40 extending to discharge the pollutants to the outside, and the drain pump 30 seated in a predetermined portion in the drain hose 40 to force the discharge of pollutants to the outside, the drain hose ( The air bell 21 to allow the water to rise smoothly to a certain portion of one side of the 40 and detects the water level rising through the air bell 21 to operate the pump limited 30 The water level sensor 20 for outputting a signal is configured to be connected.

Referring to the effect of the present invention configured in this way in detail as follows.

The present invention is to operate the drain pump in a limited manner in accordance with the signal sensed the water level in Figure 3 or 4, the washing machine in accordance with the washing process outside the drain hose 40 to discharge the contaminants from the laundry to the outside It is elongated and discharged.

At this time, the drain hose 40 is to discharge the contaminants through the drain pump 30, the drain pump 30 is the drain pump 30 only when the detection value output from the water level sensor 20 connected to one side is detected at a high water level To get rid of the pollutants.

When the water level sensor 20 raises the water by the pressure of the air that is pushed up to the water rising through the air bill during the drainage process of the washing machine, the water level sensor 20 detects the amount of water and the drain pump 30 is limited. To make it work.

The drainage pump control device of the washing machine of the present invention acting as described above limits the drainage pump to operate only when the water level sensor detects the high water level, thereby reducing power wastage and the water level rises easily through the flow of air. By detecting the residual water of the washing machine is detected to provide the effect of removing the noise caused by the residual water.

Claims (1)

A drain hose 40 extending to discharge the contaminants to the outside to complete the washing process of the laundry, and a drain pump 30 seated at a predetermined portion in the drain hose 40 to force the contaminants to be discharged to the outside. In the above, the air bell 21 to ensure that the water rises smoothly to a certain portion of the drain hose 40, and the water level rising through the air bell 21 to detect the drain pump Drainage pump control apparatus for a washing machine, characterized in that it comprises a water level sensor 20 for outputting a signal so that the operation 30 is limited.
