As shown in fig. 1, according to an embodiment of the present utility model, a laundry treating apparatus is provided.

The clothes treatment device 100 is a washing and drying integrated machine, the clothes treatment device 100 comprises a washing system, a clothes drying system and a frame, the washing system and the clothes drying system share one set of inner cylinder and one set of outer cylinder, the clothes drying system comprises an inner cylinder, an outer cylinder, a heating device and a condensing device 10, the heating device, the condensing device 10 and the outer cylinder are connected through a circulating air channel, the heating device is arranged in the circulating air channel, the condensing device 10 is a water condenser, the condensing device 10 is provided with a condensing chamber, a water inlet of the condensing chamber is communicated with an external water supply system through a water supply pipe 102, and cold water is injected into the condensing chamber through the external water supply system to supply cold energy in a drying mode of the clothes treatment device 100.

In this embodiment, as shown in fig. 1 and 2, the laundry treating apparatus 100 further includes a check valve 20, the water inlet of the condensation chamber is connected to the external water supply system through the check valve 20, and the check valve 20 is used to allow only water flow from the external water supply system to the condensation chamber and prevent water flow from the condensation chamber back to the external water supply system. Specifically, the check valve 20 includes a pipe body 22 having a working chamber 23, and a floating plug 21 movably provided in the working chamber 23, the pipe body 22 having a tubular shape, a partial region of the pipe body 22 being outwardly convex in a circumferential direction of the pipe body 22 so as to form the working chamber 23 inside the partial region of the pipe body 22. The working chamber 23 has an inlet 231 and an outlet 232 which are oppositely arranged, one end of the inlet 231 of the working chamber 23 is a water inlet end and is communicated with an external water supply system, the outlet 232 of the working chamber 23 is a water outlet end and is communicated with a water inlet of the condensing chamber, and cold water in the external water supply system flows into the condensing chamber through the inlet 231, the working chamber 23, the outlet 232 and the water inlet in sequence. The floating plug 21 is located between the inlet 231 and the outlet 232, wherein the height of the inlet 231 is higher than that of the outlet 232, when the laundry treating apparatus 100 is in an abnormal operation state, water is continuously injected into the washing and drying integrated machine to cause the water level in the condensation chamber to continuously rise, water in the condensation chamber flows back into the working chamber 23 from the outlet 232 of the working chamber 23, so that the water level in the working chamber 23 gradually rises, and under the buoyancy effect, the water in the working chamber 23 pushes the floating plug 21 to rise. When the water level in the working chamber 23 rises to or above the first preset water level, the floating plug 21 is pushed against the inlet 231 by the buoyancy, thereby closing the inlet 231 and preventing the sewage in the condensing chamber from flowing back into the external water supply system. It will be appreciated that when the water level in the working chamber 23 is at a first predetermined level, the floating plug 21 is separated from the inlet 231 by gravity, so that water in the external water supply system can be supplied to the working chamber 23 and the condensing chamber through the inlet 231, thereby restricting water flow from the external water supply system to flow unidirectionally in the direction of the condensing chamber through the check valve 20.

The position of the first preset water level is located between the inlet 231 and the outlet 232 in the vertical direction, and is related to the size and density of the floating plug 21, and the smaller the density is, the greater the distance of the position of the first preset water level from the inlet 231 in the vertical direction when the volume of the floating plug 21 is greater, whereas the smaller the volume of the floating plug 21 is, the smaller the distance of the position of the first preset water level from the inlet 231 in the vertical direction is, and thus, the position of the first preset water level is different based on the difference of the floating plug 21, which is not particularly limited herein.

The density of the floating plug 21 is smaller than that of water, and the buoyancy of the floating plug 21 is ensured to be larger than the gravity thereof.

In some embodiments, as shown in fig. 2, to prevent the floating plug 21 from blocking the outlet 232, the check valve 20 further includes a bracket 30, the bracket 30 is fixedly disposed in the working chamber 23, the bracket 30 is fixedly connected with the inner wall of the working chamber 23, the bracket 30 is disposed between the inlet 231 and the outlet 232 in a transverse direction (i.e. a direction perpendicular to the symmetry axis of the tube 22), and the bracket 30 is disposed between the floating plug 21 and the outlet 232 to separate the floating plug 21 from the outlet 232, when the water level in the working chamber 23 is lower than the second preset water level, the floating plug 21 is abutted against the bracket 30 under the action of gravity, the bracket 30 is provided with a plurality of water outlet gaps 301, and when the floating plug 21 abuts against the bracket 30, the water outlet gaps 301 are disposed between the floating plug 21 and the outlet 232, thereby preventing the floating plug 21 from blocking the outlet 232, so that water in the external water supply system can flow into the condensation chamber.

Wherein the height of the second preset water level is lower than the height of the first preset water level.

In some embodiments, as shown in fig. 3, the support 30 is in a net shape, the support 30 includes a plurality of annular ribs 32 sleeved at intervals in sequence and connecting ribs 33 extending in a radial direction and connecting all the annular ribs 32 in sequence, so that the support 30 is in a net structure as a whole, and the annular ribs 32 with the smallest inner diameter define a limiting hole 31 matched with the floating plug 21, and when the floating plug 21 is propped against the support 30 under the action of gravity, part of the floating plug 21 is accommodated in the limiting hole 31.

In this embodiment, the limiting hole 31 is disposed opposite to the inlet 231 along the vertical direction, so that the position of the floating plug 21 is limited by the limiting hole 31, so that the floating plug 21 and the inlet 231 are kept in an aligned state, and the floating plug 21 is accurately aligned and closes the inlet 231 in the lifting process.

When the water level in the working chamber 23 is lower than the first preset water level value, the second sealing portion 214 of the floating plug 21 is separated from the first sealing portion 235 by gravity so that the inlet 231 is opened and water in the external water supply system supplies cold water into the condensing chamber through the inlet 231, the working chamber 23 and the outlet 232. When the water level in the working chamber 23 is higher than the first preset water level value, the second sealing portion 214 of the floating plug 21 is inserted into the first sealing portion 235 and closes the inlet 231 under the action of the buoyancy, thereby preventing the sewage in the condensing chamber from flowing back into the external water supply system. In the present embodiment, the contact surface between the floating plug 21 and the inlet 231 is increased by the engagement of the first sealing portion 235 and the second sealing portion 214, and the connection stability between the floating plug 21 and the inlet 231 in the sealed state is improved.

In an exemplary embodiment, as shown in fig. 6 and 7, the second sealing portion 214 is tapered, the radial dimension of the second sealing portion 214 gradually decreases from the outlet 232 to the outlet 232, the profile of the first sealing portion 235 matches with the profile of the second sealing portion 214, and during the rising process of the floating plug 21, the second sealing portion 214 is axially aligned with the first sealing portion 235 through the guiding action of the tapered surface, so that the accuracy and stability of the plug-in fit between the second sealing portion 214 and the first sealing portion 235 are improved, and the sealing effect is improved. Further, the contact area between the second sealing portion 214 and the first sealing portion 235 of the floating plug 21 is increased by the engagement of the tapered surfaces, so that a better sealing effect is obtained.

By the engagement of the conical surfaces, even if the floating plug 21 deflects to some extent in the working chamber 23 under the influence of the water flow, the second sealing portion 214 is gradually axially aligned with the first sealing portion 235 during the rising of the floating plug 21 under the guiding action of the conical surfaces, and finally the insertion is achieved to seal the inlet 231.

In this embodiment, as shown in fig. 6, the second sealing portion 214 always faces the direction of the inlet 231, in order to avoid that the second sealing portion 214 cannot be smoothly inserted into the first sealing portion 235 due to the 180-degree turning of the floating plug 21 in the working chamber 23, the floating plug 21 is configured in a long strip shape extending along the axial direction of the pipe body 22, and the maximum dimension of the floating plug 21 along the axial direction of the pipe body 22 is greater than the maximum dimension of the working chamber 23 along the radial direction of the pipe body 22.

The elastic deformation performance of the sealing layer 212 is better than that of the supporting layer 211, the sealing layer 212 is a material piece with good elastic deformation performance such as a silica gel piece rubber piece, and when the floating plug 21 is propped against the inlet 231, the sealing effect of the inlet 231 is improved through the elastic deformation of the sealing layer 212.

In other embodiments, as shown in fig. 6 and 7, the floating plug 21 may also be a solid sphere, and the density of the floating plug 21 may be less than that of water.
