Problems solved by technology

[0005]The filter device in the general washing machine needs to be cleaned after it is taken out, and the filter device needs to be in contact with the washing water, so it is not suitable to use electromagnetic control methods such as setting circuits. Under the premise of setting up the line, the problem of cover recovery needs to be solved urgently

Embodiment 1

[0056] The drainage device in this embodiment is specifically a drainage pump 1, such as figure 2 and image 3 shown.

[0057] In order to prevent the drainage pump from being damaged after foreign matter enters, a filter device is generally installed at the water inlet. Since the filter device needs to regularly deal with the impurities on the filter screen, it is necessary to open the pump cover after a period of time to take out the filter device for cleaning or replacement. After the filter device is cleaned, it is necessary to return the filter device and the pump cover to ensure the tightness of the pump body, and there will be no water leakage when the drainage pump works again.

[0058] After the user cleans and replaces, it may happen that the user forgets to return or the installation is not in place, resulting in water leakage accidents during the operation of the drainage pump, increasing the cleaning burden, and serious accidents such as electric leakage. The ab...

Embodiment 2

[0077] The drainage device in this embodiment is a drainage valve.

[0078] The drain valve has a detachable valve cover and a fixed valve body at the same time. The valve body is provided with a sensing end, and the valve cover is provided with a sensed end. When the valve cover and the valve body are in different relative positions, the sensing end and the sensed end Different feedback information is generated due to different distance interactions.

[0079] In the prior art, there is a valve body used for sampling, exhaust and other functions. The valve body has an opening. When sampling, gas discharge or other needs to open the valve cover, the valve cover is separated from the valve body. If the valve cover cannot be returned in time, it will cause leakage and accidents.

[0080] The sensing end and the sensed end are arranged on the valve body and the valve cover, and the relative position information between the valve cover and the valve body can be fed back through th...

Embodiment 3

[0084] The drainage device in this embodiment takes the drainage pump as an example, and can also be a device such as a drainage valve. This embodiment and Embodiment 1 all use the principle of a magnetic switch. The difference is that this embodiment uses the principle of a reed switch proximity switch. Different feedback information is formed between the reed switch and the changing magnetic field.

[0085] The specific settings are:

[0086] The drainage pump has a pump cover and a filter device. The pump cover and the filter device are connected by buckles. After the two are connected, they can not only move in an axial direction, but also rotate relatively in the circumferential direction. pump casing.

[0087] The permanent magnet does not require circuit settings and can generate a constant magnetic field. The pump cover or filter device is provided with a permanent magnet, and the pump casing is provided with a reed switch. The magnetic field generated by the permanen...

Abstract

The invention discloses a drainage device. The device is provided with a detachable component, a fixed casing and a position detecting device; the drainage device obtains a positional relationship ofthe detachable component relative to the fixed casing. The invention discloses a washing machine provided with the drainage device and a control method of the washing method. The washing machine control system judges the position of the detachable component relative to the fixed casing through the position detecting device and performs corresponding operation. The drainage device has the advantages that the drainage device can generate a signal to judge the positional relationship without contacting, the cover body is taken down from the drainage device conveniently, the potential safety hazard of contact of a circuit and water is avoided, and the range of application is wide; the washing machine detects the position of a pump cover in the whole process of work and controls the drainage process, and then leakage events are prevented.

Description

technical field [0001] The invention belongs to the field of household appliances, and in particular relates to a drainage device, a washing machine with the drainage device and a control method for the washing machine. Background technique [0002] The washing machine drain pump generally has a filter device. In order to prevent foreign matter from entering the drain pump body and causing damage to the drain pump, a filter device is installed at the water inlet of the drain pump. The filter device is installed on one side of the drainage pump and close to the casing. An openable cover is provided so that the user can take out the filter device for cleaning by unscrewing the cover. [0003] But because the cover body is not restored to its original state in time after it is opened, or the cover body is not installed properly, it will cause the washing machine to leak water from the position of the cover body during the drainage process, causing unnecessary troubles. [0004...
