Description

The present invention relates to the technical field of a washing machine, and specifically to a control method of a washing machine.

A washing machine is designed as a device that uses electricity to wash clothes. In general, a washing machine rotates a tub for storing washing water, a rotary tub rotatably mounted inside the tub, a pulsator rotatably mounted on the bottom of the rotary tub, and a rotary tub and a pulsator. Includes motors and clutches configured as such. When the rotary tank and the pulsator rotate with the clothes and the detergent charged in the rotary tank, the pulsator agitates the washing water together with the clothes charged in the rotary tank, so that the dirt is removed from the clothes.

Larger rotary tubs are needed to increase the washing capacity of the washing machine. That is, it is necessary to increase the height or diameter of the rotary tank. However, if the rotary tank has a larger size, the storage tank and housing for accommodating the rotary tank also need to be increased with the expansion of the rotary tank.

The expansion of the housing corresponding to the appearance of the washing machine is restricted to the space of the washing machine installation area. Generally, in a user's home, the space for installing a washing machine is limited, so it is not very realistic to achieve the purpose of expanding the housing of the washing machine to increase the capacity of the washing tub. Therefore, how to increase the capacity of the rotary tub without expanding the housing of the washing machine has become a big challenge for designers.

In view of the above, the present invention is proposed.

In order to solve the above problems, an object of the present invention is to provide a method for controlling a washing machine. Specifically, the following technical measures will be adopted.

A method of controlling a washing machine, the washing machine includes a washing tub that can be used to store water during the washing process and a water collecting device for collecting water discharged from the washing tub. A catchment water level detection device is installed in the catchment device.

In the control method, when the water collecting water level detecting device detects that the washing water has entered the water collecting device in the water supply process of the washing machine, the water supply is stopped.

Further, a washing water level detecting device for detecting the water level in the washing tank is installed in the washing tank. In the above control method, when the water collecting water level detecting device does not detect the intrusion of the washing water into the water collecting device in the water supply process of the washing machine, the water level in the washing tank is set to a predetermined water level by the washing water level detecting device. Continue water supply until it is detected that the water supply has reached, and then stop water supply.

Further, the washing water level detecting device is a pressure sensor. A drainage port is opened at the bottom of the washing tank, and a drainage device is installed in the water collecting device. The drainage device includes a valve plug, and the drainage port is opened / closed by the vertical movement of the valve plug. Further, a pressure sensor for detecting the water level in the washing tank is installed above the valve plug.

When the washing water level detection device detects that the washing water has entered the water collecting device, the washing machine stops the water supply and then expands and contracts the valve plug of the drainage device N times (N is a predetermined value). If the value detected by the washing water level detector becomes smaller after the control is performed, the valve plug of the drainage device is opened and the washing water level detector detects that the water level has reached the specified washing water level. It is controlled to close after being closed. On the other hand, if the value detected by the washing water level detector does not change, the washing machine pauses and issues a warning.

Further, in the control method of the washing machine, the washing machine controls the valve plug of the drainage device to expand and contract N times after the water collecting water level detecting device stops detecting the water level.

In addition, the washing machine further includes a failure self-check program. In the failure self-check program, the washing water level detector detects that the water level in the washing tank is below a predetermined water level, and the collecting water level detecting device detects that the washing water has entered the water collecting device. If this happens, the water supply will be stopped. Then, the washing machine determines that the failure information is "a failure of the washing water level detecting device and / or the collecting water level detecting device" and displays it.

Further, a drainage port is provided at the bottom of the washing tank. Further, a drainage device capable of sealing / opening the drainage port is installed in the water collecting device, and a drainage device capable of opening / closing is installed in the washing tank. In the failure self-check program, the washing water level detector detects that the water level in the washing tank is below a predetermined water level, and the collecting water level detecting device detects that the washing water has entered the water collecting device. If this happens, the water supply will be stopped. Then, the washing machine controls to open the drainage device, and when the detection value by the washing water level detecting device does not change or becomes large, it is determined that the failure information is "failure of the washing water level detecting device". To display. On the other hand, when the value detected by the washing water level detecting device becomes small, the washing machine determines that the failure information is "failure of the collecting water level detecting device" and displays it.

Further, in the failure self-check program, the overflow water level of the washing tub is set in the washing machine. When the washing water level detector detects that the water level in the washing tank has reached the overflow water level of the washing tank, and the collecting water level detecting device detects that the washing water has entered the water collecting device, the washing machine is equipped with the washing machine. A warning is issued, and the failure information is determined to be "failure of the water supply device of the washing machine" and displayed.

Further, in the failure self-check program, the washing water level detecting device detects that the water level in the washing tank has reached the overflow water level of the washing tank, and the collecting water level detecting device allows the washing water to enter the water collecting device. If it is not detected, the washing machine issues a warning, determines that the failure information is "failure of the catchment water level detection device", and displays it.

As shown in FIG. 1, in the method of controlling the washing machine of this embodiment, the washing machine includes a washing tank that can be used for storing water in the washing process and a water collecting device for collecting water discharged from the washing tank. include. The washing tub of the washing machine in this embodiment is a water storage tub, and an outer tub is not installed outside the washing tub. Further, in this embodiment, the water collecting device is installed only at the bottom of the washing tank. Moreover, in order to measure the water level in the washing tank, it is necessary to install a water level detecting device that detects the water level in the inner tank, whereas the water collecting device is generally used only for collecting water and draining water. There is no need to detect the water level. However, if the water level detection device of the washing tank fails and the water supply for washing overflows from the balance ring of the inner tank during the water supply process, the overflowing water enters the water collecting device. At this time, if the drain port of the water collecting device is always open, the water will continue to overflow, causing extremely large loss to the equipment and the user.

In this embodiment, in order to solve such a problem, a water collecting water level detection device is installed in the water collecting device and the control method is improved to prevent overflow in the water supply process of the washing machine. do.

In the washing machine control method of the present embodiment, when the water collecting water level detecting device detects that the washing water has entered the water collecting device in the water supply process of the washing machine, the water supply is stopped.

In this embodiment, a water collecting water level detecting device is installed in the water collecting device of the washing machine.

In this embodiment, since the pressure sensor is integrated in the valve plug of the drainage device, the valve plug keeps the drain port closed during the cleaning process, and the pressure sensor on the valve plug detects the water level in the cleaning tank. Then, the purpose can be realized. According to this embodiment, the problem of water level detection when the washing tank is used as a water storage tank is solved.

However, since the washing water level detecting device is integrated in the valve plug of the drainage device, whether or not the valve plug is normally closed affects the accuracy of detection by the washing water level detecting device to some extent. Therefore, the method of controlling the washing machine in this embodiment includes the following steps.

If the washing machine stops the water supply, controls the valve plug of the drainage device to expand and contract N times (N is a predetermined value), and then the value detected by the washing water level detector becomes small, The valve plug of the drainage device is opened, and the washing water level detecting device is controlled to close the valve plug after it is detected that the water level has reached a predetermined washing water level. On the other hand, if the value detected by the washing water level detector does not change, the washing machine pauses and issues a warning.

The washing machine control method in this embodiment further includes a failure self-check program. In the failure self-check program, the washing water level detector detects that the water level in the washing tank is below a predetermined water level, and the collecting water level detecting device detects that the washing water has entered the water collecting device. If this happens, the water supply will be stopped. Then, the washing machine determines that the failure information is "a failure of the washing water level detecting device and / or the collecting water level detecting device" and displays it.

If it is detected, the water supply will be stopped. Then, the washing machine controls to open the drainage device, and when the detection value by the washing water level detecting device does not change or becomes large, it is determined that the failure information is "failure of the washing water level detecting device". To display. On the other hand, when the value detected by the washing water level detecting device becomes small, the washing machine determines that the failure information is "failure of the collecting water level detecting device" and displays it.

In the failure self-check program of this embodiment, the overflow water level of the washing tub is set in the washing machine. When the washing water level detector detects that the water level in the washing tank has reached the overflow water level of the washing tank, and the collecting water level detecting device detects that the washing water has entered the water collecting device, the washing machine is equipped with the washing machine. A warning is issued, and the failure information is determined to be "failure of the water supply device of the washing machine" and displayed.

In the failure self-check program of the present embodiment, the washing water level detecting device detects that the water level in the washing tank has reached the overflow water level of the washing tank, and the collecting water level detecting device detects the washing water to the water collecting device. If the intrusion is not detected, the washing machine issues a warning, determines that the failure information is "failure of the catchment water level detection device", and displays it.

Further, in this embodiment, the water collecting device is installed only at the bottom of the washing tank. Generally, the water collecting device has a drainage pipe for draining vertically, but when the drainage speed becomes slow due to the stagnation of the drainage pipe, the water level in the water collecting ring becomes excessively high, and the risk of overflow occurs.

Therefore, in this embodiment, the water collecting water level detecting device is installed in the water collecting device and combined with the drainage control method to prevent the risk of overflow in the drainage process of the washing machine.

In the drainage control method of the present embodiment, in the drainage process of the washing machine, drainage is temporarily stopped when the water level detected by the catchment water level detection device reaches a predetermined safe water level.

In the drainage control method of this embodiment, it is determined whether or not there is a stagnation in the drainage pipeline based on the water level detected by the catchment water level detection device. When the water level in the water collecting device reaches a predetermined safe water level, it means that the drainage pipe is stagnant, so drainage is stopped to prevent overflow.

In this embodiment, a water collecting water level detecting device is installed in the water collecting device, and the water level in the water collecting device is detected by the water collecting water level detecting device. Then, when the water level in the water collecting device reaches a predetermined safe water level, the risk of overflow in the drainage process of the washing machine is avoided by controlling the drainage to be temporarily stopped.

The drainage process is paused by controlling it to close.

As the first embodiment of the present embodiment, in the drainage control method of the washing machine in the present embodiment, the drainage temporary stop time interval T0 is set in the washing machine. When the drainage suspension time reaches the drainage suspension time interval T0, it is determined whether the water level in the water collector is lower than the predetermined safe water level, and if it is smaller, drainage is restarted, but it is smaller. If not, the drainage suspension is continued until the next drainage suspension time interval T0.

As a result, one water level detecting device is omitted, so that the entire structure is simplified and the manufacturing cost is reduced.

In addition, since the washing machine of this embodiment can detect the water level of both the washing tank and the water collecting device only by providing one water collecting water level detecting device, the water level in the water collecting device is raised in the drainage process. When it is detected that the predetermined safe water level has been reached, the valve plug operates to block the drain port of the washing tank. At this time, since the water collecting water level detection device cannot detect the water level in the water collecting device, when the water level in the water collecting device drops below the predetermined safe water level and drainage can be restarted.
