Example 2

Referring to fig. 6, the washing machine according to another embodiment of the present invention further includes the lint collecting device, a first drain pipe 1, and a drain pipe connected to the first drain pipe, the lint collecting device 2 is detachably installed in the first drain pipe 1, a water pump 121 and a reversing valve 13 are sequentially installed on the drain pipe, an outlet of the reversing valve 13 is connected to a circulation pipe 12, one end of the circulation pipe 12, which is far from the reversing valve 13, is connected to an inner tub of the washing machine, another outlet of the reversing valve 13 is connected to a second drain pipe 11, a sealed space is formed between a support plate and a fixing table of the lint collecting device and the first drain pipe, the drain pipe is connected to the sealed space, an outlet of the second drain pipe is installed on a wall and is connected to a household sewer pipe, and the main purpose of the present invention is to discharge sewage of washed laundry from the sewer pipe directly through the water pump, the existing direct drainage method needs to ensure that a water outlet is lower on one hand, otherwise water is easy to remain, and on the other hand, the existing direct drainage method directly drains on the ground and also needs to clean the ground.

The first drainage pipe of the washing machine is stretchable close to one side connected with the plush collecting device, when the power failure phenomenon occurs, the plush collecting device is pulled outwards, the stretchable first drainage pipe is pulled out by the plush collecting device, then the plush collecting device is taken down from the first drainage pipe, and then the outlet of the first drainage pipe is put into a basin or directly put on the ground.

For the washing machine with the lint collecting device arranged at the position of the circulating water pump, an alarm device can be arranged in the washing machine, the alarm device 14 is fixed in the washing machine and is electrically connected with a control panel of the washing machine, a convex block 242 is arranged on the outer side wall of a filter pipe 24 of the lint collecting device 2, a contact 15 matched with the convex block 242 is arranged on the inner wall of a first drainage pipe 1, the contact 15 is electrically connected with the alarm device 14, when the blocking phenomenon occurs, the filter pipe moves towards the direction far away from a fixed platform under the action of water pressure, when the convex block on the filter pipe moves to the contact, the convex block extrudes the contact, the circuit of the alarm device electrically connected with the contact is conducted, the alarm device sends out an alarm signal to prompt a user to clean the lint collecting device, at the moment, a limit block is required to be arranged on the inner wall of the first drainage pipe, the pressure relief pipe can not move continuously to ensure the continuous energization of the alarm device, and the working principle of the alarm device is to ensure that the pressure relief pipe can move relative to the first drainage pipe, namely, the contact on the filter pipe can move relative to the first drainage pipe, so that the alarm effect is achieved.

The washing machine with the circulating water pump generally arranges a filter screen at a water inlet of the water pump, but the existing filter screen mainly filters some larger impurities, avoids the damage to the water pump and cannot collect the lint.

The working process, when the water in the washing machine circulates, the water in the inner barrel enters the first drainage pipe from the circulating water inlet, and enters the inner cavity of the filter pipe from the support plate of the first drainage pipe, through setting the support plate to be in interference fit with the inner wall of the first drainage pipe, basically no water flow enters the water pump from between the lint collecting device and the first drainage pipe, which affects the lint collecting effect, the water is re-conveyed into the inner barrel by the water pump after being filtered by the filter screen on the side wall of the filter pipe, when the water in the inner barrel needs to be discharged, the water pump is only closed, and the drainage valve on the second drainage pipe is opened, in addition, the sewage after the washing is finished can be conveyed to a sewer through the water pump to be discharged, the change of the water path of the water pump can be realized through the reversing valve or the positive and negative rotation of the water pump, the fixed platform is set to be transparent, so, convenience of customers judges whether to wash the device, in addition, when blocking phenomenon appears in the cleaning process, the water pressure increase, promote the pressure release pipe along the bracing piece to the one side motion of keeping away from the fixed station, part pressure release hole exposes this moment, the circulating water can be directly get into the water pump from the pressure release hole, thereby reach the purpose of pressure release, thereby produce bigger destruction to the water pump from pressure release hole entering water pump in order to prevent the plush of collecting at the pressure release in-process, can also set up the must of falling that the filter tube extends earlier on at the pressure release pipe. In addition, an alarm device is further arranged in the washing machine, when the convex block on the filter pipe moves to be in contact with the contact point on the inner wall of the first drainage pipe, the supporting plate is just blocked by the limiting block arranged in the first drainage pipe, at the moment, the convex block and the contact point are always in a contact state, the alarm device is continuously powered on, an alarm signal is generated, and a user is prompted to clean the lint collecting device.

When the lint collecting device needs to be cleaned in the washing process, the circulating water pump needs to be closed, meanwhile, the drain valve of the inner barrel needs to be closed, then the lint collecting device is taken out of the washing machine for cleaning, the support plate and the filter pipe are separated firstly during cleaning, then the filter pipe and the pressure relief pipe are separated, then cleaning is carried out one by one, and after cleaning is finished, the lint collecting device is assembled together and then fixed on the first drain pipe.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
