The working principle of the clothes dryer in the current market is as follows: the fan rotates to enable air to circularly flow, the heating device heats the air and then enters the roller, the hot air passes through wet clothes and then takes away water vapor, the water vapor continuously flows through the cooling device to generate condensed water, and then the condensed water passes through the heating device to change the hot air and then enters the roller, and the circulation is carried out until the clothes are completely dried. The condensed water generated during the air circulation process may be stored in a fixed water container by a drain pump or directly discharged to the outside of the machine.
Referring to fig. 1, fig. 1 is a block diagram of an existing dryer shown in an exemplary embodiment, and as shown in fig. 1, a drum, a front air duct, a bottom air duct, a fan, a rear air duct, and the like of the dryer form a gas circulation system, and in the process of drying clothes by a heat pump dryer or a condensation dryer, the fan drives gas to circulate, and the fan pumps the gas in the bottom air duct to the rear air duct, which causes negative pressure in the bottom air duct and positive pressure in the rear air duct. In order to discharge condensed water formed in the condensation process, the conventional heat pump clothes dryer and the condensation clothes dryer are provided with a normally-open channel for the condensed water to pass through, the channel is used for conducting the water storage tank in the air channel with the external water storage tank, the condensed water in the air channel flows into the external water storage tank through the channel, and then the condensed water is discharged into a water storage device at the top of the clothes dryer or into a sewer pipeline through a drainage pump in the external water storage tank.
The drainage mode has two disadvantages:
the air pressure in the first air channel and the air pressure in the bottom air channel is smaller than the ambient air pressure, the air above the air channel outer water storage part does not circulate and is the normal ambient air pressure, so that air pressure difference can be generated at two sides of the air channel, at the moment, if the air channel outer water storage part has water, the water of the air channel outer water storage part can flow to the air channel inner water storage part, and if the air channel outer water storage part does not have water, the terminal condensed water of the air channel inner water storage part can not be discharged to the air channel outer water storage part through the air channel.
Secondly, because the existence of the air pressure difference on two sides of the channel, air enters the air circulation system from the channel, so that the air pressure of the air channel circulation system is increased, water vapor or filth of the air channel circulation system is easy to leak to other parts of the clothes dryer from the front sealing part or the rear sealing part of the roller, such as a circuit board, a large amount of water vapor and filth can be accumulated in the clothes dryer for a long time, and then the potential safety hazard is brought, and the service life of the clothes dryer is reduced.
Referring to fig. 2, fig. 2 is a structural view of a drain device of a clothes dryer according to an exemplary embodiment of the present application, and as shown in fig. 2, a drain device M of a clothes dryer according to the present application includes an in-duct water storage member 100, an out-duct water storage member 300, and a sealing member 200.
The water storage part 100 in the air duct is a container for storing water, such as a water storage tank, and the water storage part 100 in the air duct is positioned in the air duct and used for collecting condensed water generated in the air duct of the clothes dryer.
The air-duct outer water storage member 300 is a container for storing water, such as a water storage tank, and the air-duct outer water storage member 300 is located outside the air duct, communicates with the air-duct inner water storage member 100 through a first through hole 11 formed in the air-duct wall 10 of the dryer, and receives condensed water flowing out of the air-duct inner water storage member 100. In this embodiment, the first through hole 11 is opened in the air duct wall 10 of the clothes dryer, and the air duct wall 10 is a side wall of the air duct between the air duct inner water storage member 100 and the air duct outer water storage member 300.
Illustratively, the whole air duct is taken as the air duct inner water storage member 100, at this time, the bottom air duct receives condensed water generated by the clothes dryer, the first through hole 11 is formed in the side wall of the air duct inner water storage member 100, the side wall provided with the first through hole 11 is located between the air duct inner water storage member 100 and the air duct outer water storage member 300, and the side wall provided with the first through hole 11 is taken as one side wall of the air duct outer water storage member 300.
Illustratively, the plane of the bottom of the air channel inner water storage member 100 is higher than the plane of the lower edge of the first through hole 11, and the plane of the lower edge of the first through hole 11 is higher than the plane of the top of the air channel outer water storage member 300, and in addition, the first through hole 11 may be opened at the bottom of the air channel wall 10, so that the condensed water can be smoothly discharged.
The shape of the first through hole 11 is not limited in this embodiment, and may be a regular geometric shape, such as a rectangle, a circle, or an irregular geometric shape.
The sealing member 200 seals the first through hole 11 when the dryer is operated, or conducts the first through hole 11 by the pressure of the condensed water discharged from the air course inside the water storage member 100 when the dryer is stopped.
Illustratively, the seal 200 may be an elastomeric plate, such as a rubber plate for the seal 200.
Illustratively, in the case where the seal member 200 is in a naturally stretched state (i.e., no deformation occurs) and is capable of completely covering the first through-hole 11, the seal member 200 is provided with a size as small as possible, such as the shape and size of the seal member 200 being equal to the first through-hole 11 or slightly larger than the first through-hole 11. The sealing member 200 is provided with as small a mass as possible, and the sealing member 200 may be made of a light material, for example, an elastic rubber, so that condensed water in the water storage member 100 in the air duct is discharged.
When the clothes dryer dries clothes, due to the effect of the air pressure difference between the inner side and the outer side of the air channel wall 10 provided with the first through hole 11, the pressure in the air channel is larger than the pressure of condensed water discharged by the water storage part 100 in the air channel to the outside of the air channel of the sealing part 200, and at the moment, the sealing part 200 is tightly attached to the first channel 11 to seal the first through hole 11, so that external air cannot enter the air channel, the air pressure in the air channel is increased, and water vapor or burrs are leaked to other parts of the clothes dryer, so that potential safety hazards are brought. When the clothes dryer stops running, the air pressure inside and outside the air duct is equal, and at the moment, under the pressure of the condensed water of the water storage part 100 in the air duct, the sealing part 200 deforms towards the direction of the water storage part 300 outside the air duct so as to conduct the first through hole 11, and then the condensed water of the water storage part 100 in the air duct flows to the water storage part 300 outside the air duct through the first channel 11.
Illustratively, the drainage device M provided in the present embodiment further includes a drainage pump (not shown) disposed in the air-duct-external water storage 300, and a drainage pipe (not shown) disposed from the air-duct-external water storage 300 to the outside of the clothes dryer, the drainage pump being matched with the drainage pipe to drain water in the air-duct-external water storage 300 out of the clothes dryer.
The drainage device M of the clothes dryer provided by the embodiment comprises a water storage piece 100 in an air duct, and is used for collecting condensed water generated by the clothes dryer; the air duct outer water storage 300 is communicated with the air duct inner water storage 100 through a first through hole 11 formed on the air duct wall 10 of the clothes dryer, and is used for receiving condensed water flowing out of the air duct inner water storage 100; the sealing member 200 seals the first through hole 11 when the dryer is operated, or conducts the first through hole 11 by the pressure of the condensed water discharged from the in-duct reservoir 100 when the dryer is stopped. On the one hand, when the clothes dryer is in operation, the air pressure in the bottom air channel is lower than the air pressure in the space where the water storage piece 300 outside the air channel is located, and at the moment, the sealing piece 200 is used for sealing the first channel 11, so that the pressure in the air channel is prevented from being increased due to the fact that external air enters the air channel, and then water vapor and burrs in the air channel are easy to leak to other parts of the clothes dryer from the air channel, and potential safety hazards are brought to the clothes dryer; on the other hand, when the dryer stops running, the air pressure at the bottom of the air channel is the same as the air pressure of the space where the air channel outer water storage part 300 is located, at this time, under the pressure of the condensed water in the air channel inner water storage part 100, the first channel 11 is conducted, so that the condensed water flows into the air channel outer water storage part 300 through the first channel 11, and further the condensed water is smoothly discharged.

The sealing part 220 is tightly attached to the first through hole 11 to seal the first through hole 11 when the dryer is in operation, so that external air cannot enter the air duct, the air pressure in the air duct is increased, and then water vapor or filth is leaked to other parts of the dryer, so that potential safety hazards are brought. Or when the dryer stops running, deformation along the direction of the air channel outer water storage member 300 is generated under the pressure of the condensed water discharged from the air channel inner water storage member 100 to conduct the first through hole 11, so that the condensed water of the air channel inner water storage member 100 flows to the air channel outer water storage member 300 through the first channel 11.
In one embodiment, the fixing portion 210 and the sealing portion 220 are made of the same material, and are integrally formed.
Optionally, a protrusion is formed on one side of the sealing member 200, and the protrusion is used as a fixing portion 210 in interference fit with the mounting hole 12, so as to fix one side of the sealing member 200 on the air duct wall 10, and when the other side of the sealing member 200 is subjected to the pressure of the condensed water or the air pressure difference on both sides of the air duct, since one side of the sealing member 200 is fixed on the mounting hole of the air duct wall 10, it is ensured that the sealing member 200 does not fall off the air duct wall 10 completely.
Interference means that the difference between the size of the hole minus the size of the mating shaft is negative. An interference fit refers to a fit with an interference (including a minimum interference equal to zero). At this time, the tolerance zone of the hole is below the tolerance zone of the shaft, the algebraic difference obtained by subtracting the dimensions of the matched shaft in the respective directions from the dimensions of the hole in the respective directions is an interference fit when the difference is negative.
Optionally, the drain device M further includes a blocking member (not shown) for fixing the fixing portion 210 to the duct wall 10 of the dryer. One side of the sealing member 200 forms a protrusion penetrating the mounting hole 12 of the duct wall 10 as a fixing portion 210, and the blocking member is engaged with an end of the protrusion so that the sealing member 200 does not come off the duct wall 10. Optionally, the protruding end of the fixing portion 210 is provided with a plurality of threads, and the blocking portion is a nut engaged with the plurality of threads.

On the one hand, because the dryer is when the operation, the atmospheric pressure in the bottom wind channel is lower than the atmospheric pressure in the space that wind channel outer water storage spare 300 is located, utilize sealing member 200 to seal first passageway 11 this moment, can avoid external gas to get into the wind channel, and then bring the potential safety hazard for the dryer, in addition, when the dryer stops the operation, the atmospheric pressure in wind channel bottom is the same with the atmospheric pressure in the space that wind channel outer water storage spare 300 is located, at this moment, under the pressure effect of the condensate water in wind channel inner water storage spare 100, switch on first passageway 11 for the condensate water flows into wind channel outer water storage spare 300 through first passageway 11, and then discharges the comdenstion water smoothly.
