[0002] Taking a washing and drying integrated machine as an example, a condenser is generally used in a drying process to dehumidify a wet and hot airflow. The working principle of the condenser is as follows: a condensing liquid is sprayed out through an outlet passage of the condenser, and exchanges heat with the wet and hot airflow in a condensing passage. The wet and hot air is cooled to below the dew point, so that the wet and hot air precipitates moisture, and is discharged from the condenser together with the condensing liquid.

[0045] The present application will be further described in detail below in combination with the drawings and specific embodiments.

[0046] The embodiments of the present application provide a clothes treatment apparatus, which includes a drum assembly and the condenser of any one of the embodiments of the present application.

[0047] The clothes treatment apparatus may, for example, be a clothes dryer, a washer-dryer, etc., which is not limited herein.

[0048] The inner part of the drum assembly has a laundry treatment cavity in which the laundry is subjected to washing, dehydration or drying and other washing and treating operations.

[0049] The condenser is arranged on the drum assembly. Exemplarily, the drum assembly can include an inner drum and an outer drum, the inner drum is provided with the laundry treatment cavity, and the inner drum is rotatably supported in the outer drum, and the condenser is arranged on the outer drum.

[0050] The condenser is used to dehumidify the humid and hot air flow generated in the laundry treatment cavity. The specific working principle is that the condenser is supplied with condensing liquid, the humid and hot air flow in the laundry treatment cavity enters the condenser and exchanges heat with the condensing liquid in the condenser, the humid and hot air is cooled to below the dew point, so that the humid and hot air releases water, and the water is discharged from the condenser together with the condensing liquid. The humid and hot air after condensation becomes relatively dry cold air.

[0051] The specific type of the condensing liquid is not limited. Exemplarily, the condensing liquid can be water.

[0052] A heating channel is arranged downstream of the condenser, and the space of the heating channel and the inner space of the condenser together constitute a drying channel of the laundry treatment device. A fan and a heater are arranged in the heating channel. The dry cold air flowing out of the condenser flows through the heater, the heater heats the dry cold air and makes it become dry hot air, and the dry hot air returns to the laundry treatment cavity for drying the laundry. In this way, the air flow circulates between the laundry treatment cavity and the drying channel, realizing continuous drying of the laundry, and the fan provides power for the circulation of the air flow.

[0053] It can be understood that in the process of circulating flow, the air flow may carry the lint of the laundry into the drying channel. If no filter screen is arranged in the drying channel, the lint will adhere to the drying channel and block the drying channel, and will breed bacteria if not cleaned for a long time. If a filter screen is arranged in the drying channel to filter the lint in the air flow, the filter screen is difficult to be taken out for cleaning because it is arranged in the drying channel. Even if the filter screen is cleaned in the drying channel, the cleaning liquid is difficult to uniformly cover the filter screen, so that part of the lint may remain on the filter screen and cannot be cleaned, which will block the drying channel for a long time, cause the air flow to decrease, and affect the drying efficiency.

[0054] Therefore, the present application further provides a condenser, please refer to Figure 1 , Figure 1 FIG. 1 is a structural schematic diagram of the condenser according to an embodiment of the present application. The condenser includes a shell assembly 10 and a pressure relief assembly 20.

[0055] The shell assembly 10 is provided with a liquid inlet cavity 10a, a liquid outlet 13c and a condensing channel 10b. The liquid inlet cavity 10a is communicated with the liquid outlet 13c and the condensing channel 10b, and the condensing liquid can enter the liquid inlet cavity 10a and be sprayed as a water mist surface transversely across the condensing channel 10b through the liquid outlet 13c.

[0056] It should be noted that the specific structure of the liquid outlet 13c is not limited. Exemplarily, the shell assembly is provided with a liquid outlet channel 13a, one end of the liquid outlet channel 13a is the liquid outlet 13c, and the other end of the liquid outlet channel 13a is in communication with the liquid inlet cavity 10a.

[0057] The cross-condensation channel 10b refers to the state that the water mist surface is not parallel to the extension direction of the condensation channel. In this way, at least part of the airflow can pass through the water mist surface when the airflow flows through the position where the water mist surface is located.

[0058] The condensation channel 10b is a place where the wet hot airflow exchanges heat with the condensate. The condensation channel 10b is in communication with the clothes treatment cavity, and the wet hot airflow in the clothes treatment cavity enters the condensation channel 10b and dehumidifies in the condensation channel 10b.

[0059] During use of the clothes treatment apparatus, the condenser is supplied with condensate through the liquid supply pipeline. Specifically, the liquid supply pipeline is in communication with the liquid inlet cavity 10a, and after the condensate flows out from the liquid supply pipeline, it successively passes through the liquid inlet cavity 10a and the liquid outlet channel 13a and enters the condensation channel 10b.

[0060] The liquid inlet cavity 10a and the liquid outlet channel 13a are both part of the flow path of the condensate, and the liquid outlet 13c is located in the condensation channel 10b.

[0061] In the condensation channel 10b, the liquid outlet 13c sprays the condensate and forms a large number of small particles, and the small particles enclose a certain volume shape, and the surface of the volume shape is called a water mist surface.

[0062] When the wet hot airflow with lint flows through the water mist surface, the wet hot airflow exchanges heat with the condensate in the form of water mist, and the condensate in the related art flows in the form of a single column or multiple columns in the condenser. The heat exchange area between the condensate and the wet hot airflow is relatively small, and the heat exchange efficiency is low, which affects the drying efficiency of the clothes. However, the condenser of the present application can spray the condensate and form a water mist surface that crosses the condensation channel 10b. The surface area of the water mist surface is relatively large, that is, the heat exchange area with the wet hot airflow is also relatively large, thereby improving the heat exchange efficiency between the condensate and the wet hot airflow, and further improving the drying efficiency of the clothes treatment apparatus.

[0063] In addition, the lint in the wet hot airflow is slowed down, wetted, and weighted, and no longer advances with the airflow. That is, the water mist surface has a filtering effect on the circulating airflow in the clothes treatment apparatus, thereby reducing the possibility of lint remaining in the drying channel, thereby ensuring the air volume in the drying channel, and further improving the drying efficiency of the clothes treatment apparatus.

[0064] It can be understood that, due to the filtering effect of the water mist surface, the filter element for filtering the lint in the drying channel can be omitted, and cleaning of the filter element is no longer required, thereby saving the components for cleaning the filter element. In this way, the components of the clothes treatment apparatus are relatively less, which is conducive to improving the production cost and production efficiency of the clothes treatment apparatus.

[0065] It should be noted that, in a plane perpendicular to the axial direction of the liquid outlet channel 13a, the cross-sectional area of the liquid inlet cavity 10a intercepted by the plane can be greater than the cross-sectional area of the liquid outlet channel 13a intercepted by the plane. On the one hand, since the condensate in the liquid supply pipeline will first enter the liquid inlet cavity 10a, and the cross-sectional area of the liquid inlet cavity 10a is relatively large, the condensate is facilitated to enter, and the connection between the liquid supply pipeline and the liquid inlet cavity 10a is subjected to relatively small pressure, which is conducive to reducing the risk of the liquid supply pipeline falling off the condenser; on the other hand, since the condensate will enter the condensation channel 10b after passing through the liquid outlet channel, and the cross-sectional area of the liquid outlet channel 13a is relatively small, it is conducive to increasing the pressure of the condensate sprayed out of the outlet of the liquid outlet channel 13a, facilitating the condensate to be in the form of a water mist surface after being sprayed out, and the water mist surface has a larger contact area with the humid hot airflow and a higher heat exchange efficiency, thereby the dehumidification effect of the condenser is better.

[0066] The specific shape of the condensation channel 10b is not limited. For example, as shown in Figure 1 , the condensation channel 10b includes a first flow channel 10b1 and a second flow channel 10b2 arranged at an angle, the first flow channel 10b1 extends along the height direction of the condenser, the first flow channel 10b1 has an air inlet, and the second flow channel 10b2 is located downstream of the first flow channel 10b1. The airflow in the clothes treatment cavity enters the first flow channel 10b1 through the air inlet.

[0067] It should be noted that, when the condenser is used in the clothes treatment apparatus, the height direction of the condenser is consistent with the height direction of the clothes treatment apparatus. Specifically, the height direction of the condenser is indicated by “H” in Figure 1 or Figure 2 .

[0068] Along the flow path of the airflow in the condensation channel 10b, the liquid outlet 13c can be arranged in the first flow channel 10b1. Since the first flow channel 10b1 and the second flow channel 10b2 are arranged at an angle, the condensate and the humid hot airflow condensed into condensate water are more difficult to enter the second flow channel 10b2 located downstream of the flow path.

[0069] It can be understood that the wet hot air forms dry cold air after passing through the condenser, the dry cold air enters the heating channel and is heated by the heater to form dry hot air, and the dry hot air returns to the clothes treatment cavity again for drying clothes. That is, by arranging the condensing channel 10b to include two sections of channels, the first flow channel 10b1 and the second flow channel 10b2, the probability of the condensate and the condensate water formed by the condensation of the wet hot air entering the heating channel is reduced, and the heat generated by the heater can be more used for heating the air entering the heating channel, thereby improving the drying efficiency of the clothes.

[0070] The liquid inlet cavity 10a is arranged at the top of the first flow channel 10b1. In this way, the liquid outlet 13c is arranged at the top of the first flow channel 10b1. After the condensate leaves the area where the water mist is located, it can flow downward under the action of gravity, thereby flowing a distance in the first flow channel 10b1. During the flowing of the condensate in the first flow channel 10b1, the wet hot air can be dehumidified, thereby improving the dehumidification effect of the condenser.

[0071] It should be noted that the specific manner in which the shell assembly 10 defines the condensing channel 10b is not limited.

[0072] Exemplarily, referring to Figure 1 , the shell assembly 10 includes a first sub-shell 11 and a second sub-shell 12, and the first sub-shell 11 and the second sub-shell 12 are abutted and define the condensing channel 10b.

[0073] In this way, the condensing channel 10b is formed by the partial wall of the first sub-shell 11 and the partial wall of the second sub-shell 12, and the first sub-shell 11 and the second sub-shell 12 can be respectively molded and easily demolded, thereby reducing the molding difficulty of the condensing channel 10b.

[0074] The shell assembly 10 is also provided with a pressure relief channel 10c, both ends of the pressure relief channel 10c are respectively communicated with the liquid inlet cavity 10a and the outside of the liquid inlet cavity 10a, and at least part of the pressure relief assembly 20 is arranged in the pressure relief channel 10c and used for selectively opening or blocking the pressure relief channel 10c.

[0075] In the related art, in order to facilitate the condensate sprayed through the liquid outlet to form a water mist surface, the diameter of the liquid outlet is generally relatively small. During a long period of use, the liquid outlet may be blocked. After the liquid outlet is blocked, the condensate in the liquid inlet cavity cannot be discharged to achieve the condensation effect. After the liquid inlet cavity is filled with condensate, the condensate in the liquid supply pipeline cannot enter the liquid inlet cavity, so that the pressure in the liquid supply pipeline cannot be released, thereby possibly causing the liquid supply pipeline to burst, which has a safety risk, and the reliability of the condenser is relatively poor.

[0076] It should be noted that the technical solutions provided in the related art are intended to provide background or context for the embodiments of the present application. The description herein is not admitted to be prior art merely because it is included in this section.

[0077] In the condenser provided by the embodiment of the present application, when the condensate can be normally sprayed out of the liquid outlet 13c, the pressure relief assembly 20 blocks the pressure relief channel 10c, and the condensate in the liquid inlet cavity 10a cannot flow out of the pressure relief channel 10c, but is sprayed out of the liquid outlet 13c. Thus, the pressure of the liquid outlet 13c can be guaranteed, so as to facilitate the formation of a water mist surface in the condensing channel 10b. The water mist surface can have a certain filtering effect on the lint and thread scraps, and has a larger contact area with the wet hot airflow and a better heat exchange effect. After the liquid outlet 13c is blocked, the pressure relief assembly 20 conducts the pressure relief channel 10c, and the condensate in the liquid inlet cavity 10a is discharged through the pressure relief channel 10c. The pressure in the liquid inlet cavity 10a can be released, which is conducive to reducing the probability of burst of the liquid supply pipeline connected to the liquid inlet cavity 10a, and further conducive to improving the reliability of the condenser.

[0078] It should be noted that the specific position of the "outside of the liquid inlet cavity 10a" is not limited.

[0079] Exemplarily, the "outside of the liquid inlet cavity 10a" can be the outside of the condenser, that is, the condensate discharged through the pressure relief channel 10c is directly discharged to the outside of the condenser.

[0080] Exemplarily, the "outside of the liquid inlet cavity 10a" can also be in the condensing channel 10b. In this way, the condensate discharged through the pressure relief channel 10c can still enter the condensing channel 10b, so as to be used for dehumidifying the wet hot airflow, and conducive to guaranteeing the dehumidifying effect of the condenser on the wet hot airflow.

[0081] The specific structure of the first sub-shell 11 is not limited.

[0082] Exemplarily, referring to Figure 5 , the first sub-shell 11 includes a body 111 and a protruding portion 112 arranged on the side of the body 111 facing the condensing channel 10b. The shell assembly 10 further includes a third sub-shell 13, which is arranged on the protruding portion 112 and cooperates with the protruding portion 112 to define the liquid inlet cavity 10a and the pressure relief channel 10c.

[0083] The body 111 and the protruding portion 112 can be an integrally formed structure. Of course, the body 111 and the protruding portion 112 can also be a split structure, and the body 111 and the protruding portion 112 of the split structure are assembled to obtain the first sub-shell 11.

[0084] In the embodiment, the liquid inlet cavity 10a and the pressure relief channel 10c are both defined by the protruding portion 112 and the third sub-shell 13, that is, the protruding portion 112 and the third sub-shell 13 can be respectively molded, and the difficulty of the molding is relatively low, thereby facilitating the reduction of the molding difficulty of the liquid inlet cavity 10a and the pressure relief channel 10c.

[0085] In an embodiment, referring to Figure 3 and Figure 5 , the protruding portion 112 is provided with a first cavity 112a and a second cavity 112b which are in communication with each other, and the first cavity 112a and the second cavity 112b both have an open side, the third sub-shell 13 and the inner wall of the first cavity 112a define the liquid inlet cavity 10a, and the third sub-shell 13 and the inner wall of the second cavity 112b define the pressure relief channel 10c.

[0086] For example, the open sides of the first cavity 112a and the second cavity 112b are located on the same side, so that the third sub-shell 13 is a flat plate and can cover the open sides of the first cavity 112a and the second cavity 112b at the same time, and the structure of the third sub-shell 13 is simpler.

[0087] In the embodiment, the mold can exit the first cavity 112a through the open side of the first cavity 112a, and can also exit the second cavity 112b through the open side of the second cavity 112b, and the difficulty of the first sub-shell 11 is relatively low.

[0088] The specific structure of the pressure relief assembly 20 is not limited.

[0089] In an embodiment, referring to Figures 2 to 4 , the pressure relief assembly 20 includes a pressure relief valve 21.

[0090] At least part of the pressure relief valve 21 is arranged in the pressure relief channel 10c. That is, the pressure relief valve 21 can be completely located in the pressure relief channel 10c; or a part of the pressure relief valve 21 is located in the pressure relief channel 10c, and the other part is located outside the pressure relief channel 10c.

[0091] The pressure relief valve 21 has a first position and a second position. In the first position, the pressure relief channel 10c is in a blocked state. In the second position, the pressure relief channel 10c is in a conductive state.

[0092] In the first position, the condensate in the liquid inlet cavity 10a cannot be discharged through the pressure relief channel 10c; in the second position, the condensate in the liquid inlet cavity 10a can be discharged through the pressure relief channel 10c.

[0093] In some embodiments, the pressure relief valve 21 moves along an axial line of the pressure relief passage 10c to switch between the first position and the second position. That is, the moving direction of the pressure relief valve 21 is close to parallel with the flowing direction of the condensate in the pressure relief passage 10c, and thus the pressure relief valve 21 can be switched from one of the first position and the second position to the other position by means of the pressure of the condensate.

[0094] Specifically, referring to Figure 3 and Figure 4 , the pressure relief valve 21 is in the first position under the action of other components. The other components can be, for example, the elastic return member 22, which is taken as an example below:

[0095] When the liquid outlet passage 13a can normally spray out the condensate, the pressure of the condensate in the liquid inlet cavity 10a is not enough to overcome the force of the elastic return member 22 on the pressure relief valve 21, and the pressure relief valve 21 can be relatively stably in the first position, and the pressure relief passage 10c is in the blocked state. After the liquid outlet passage 13a is blocked, as the pressure of the condensate in the liquid inlet cavity 10a gradually increases, when the pressure of the condensate increases to exceed the force of the elastic return member 22 on the pressure relief valve 21, the pressure relief valve 21 gradually moves to the second position, the pressure relief passage 10c is in the open state, the condensate is discharged through the pressure relief passage 10c, and the pressure in the liquid inlet cavity 10a is released, thereby reducing the probability of explosion of the liquid supply pipeline.

[0096] In this embodiment, the movement mode of the pressure relief valve 21 when switching between opening and blocking the pressure relief passage 10c is relatively simple, and the probability of interference with other structures when the pressure relief valve 21 moves along the axial direction of the pressure relief passage 10c is low, thereby facilitating improvement of the reliability of the pressure relief valve 21.

[0097] In other embodiments, the pressure relief valve 21 can also be a double-leaf door structure, and a pressure sensor can be arranged in the pressure relief passage 10c. When the detected pressure is greater than a certain value, the double-leaf door structure is controlled to open, and thus the pressure relief passage 10c is in the open state; when the detected pressure is less than a certain value, the double-leaf door structure is controlled to close, and thus the pressure relief passage 10c is in the blocked state.

[0098] In an embodiment, referring to Figures 2 to 4 , the pressure relief passage 10c comprises a first sub-passage 10c1, one end of the first sub-passage 10c1 is provided with a flow port 10c2, the first sub-passage 10c1 communicates with the liquid inlet cavity 10a through the flow port 10c2, and the inner wall surface of the first sub-passage 10c1 comprises an annular end surface 112c, which surrounds to form the flow port 10c2. It is provided that

[0099] In the first position, the pressure relief valve 21 abuts against the annular end face 112c and closes the flow port 10c2.

[0100] In the second position, there is a gap between the pressure relief valve 21 and the annular end face 112c.

[0101] In this way, the pressure relief valve 21 can be switched between abutting against the annular end face 112c and separating from the annular end face 112c during the linear movement of the pressure relief valve 21 along the axial direction of the pressure relief passage 10c, so as to realize the opening and closing of the pressure relief valve 21. Such a structure is relatively simple and easy to realize.

[0102] It can be understood that the diameter of the flow port 10c2 is relatively small compared to the diameter of the first sub-passage 10c1, and the peripheral side wall of the pressure relief valve 21 is provided with a gap with the peripheral side wall of the first sub-passage 10c1. For example, a groove can be provided on the peripheral side wall of the pressure relief valve 21 or the side wall of the first sub-passage 10c1, the groove extending along the axial direction of the first sub-passage 10c1, and the groove constitutes the gap between the peripheral side wall of the pressure relief valve 21 and the peripheral side wall of the first sub-passage 10c1. In the second position, the condensed liquid can flow out of the first sub-passage 10c1 through the gap after flowing through the annular end face 112c.

[0103] In addition, the gap between the peripheral side wall of the pressure relief valve 21 and the peripheral side wall of the first sub-passage 10c1 is formed by the groove, and the peripheral side wall of the first sub-passage 10c1 and the peripheral side wall of the pressure relief valve 21 are in a state of substantially abutting, so as to facilitate reducing the probability of the pressure relief valve 21 shaking in the first sub-passage 10c1 along the radial direction of the first sub-passage 10c1.

[0104] It should be noted that the "state of substantially abutting" refers to a state in which one can slide on the surface of the other.

[0105] In an embodiment, referring to Figures 2 to 4 , the pressure relief valve 21 further comprises an elastic reset member 22. When the pressure relief valve 21 moves from the first position to the second position, the elastic reset member 22 is elastically deformed. The elastic reset member 22 restores the elastic deformation to push the pressure relief valve 21 from the second position to the first position.

[0106] The specific type of the elastic reset member 22 is not limited. For example, it can be a compression spring, a tension spring, etc.

[0107] When the pressure of the condensate in the liquid inlet cavity 10a is high, the condensate can push the pressure relief valve 21 to move from the first position to the second position, and at this time, the elastic reset member 22 will be elastically deformed. When the pressure inside the liquid inlet cavity 10a decreases to be insufficient to overcome the elastic force of the elastic reset member 22, the elastic reset member 22 can gradually push the pressure relief valve 21 to reset to the first position. In this way, the pressure relief valve 21 can realize automatic conduction and isolation of the pressure relief channel 10c, and this structure is relatively simple and easy to implement.

[0108] In this embodiment, the annular end face 112c can also generate a certain stopping action on the pressure relief valve 21. When the pressure relief valve 21 moves from the second position to the first position, the annular end face 112c stops the pressure relief valve 21, and the pressure relief valve 21 can just move to the first position.

[0109] The mounting structure of the elastic reset member 22 is not limited.

[0110] In one embodiment, please refer to Figures 2 to 4 , Figure 6 The pressure relief valve 21 is provided with an annular groove 21a, which is located in the first sub-channel 10c1 and extends along the axial direction of the first sub-channel 10c1. One end of the annular groove 21a is open away from the flow port 10c2, one end of the elastic reset member 22 is arranged in the annular groove 21a, and the other end extends along the axial direction of the first sub-channel 10c1 and is arranged on the inner wall of the first sub-channel 10c1.

[0111] Here, the other end of the elastic reset member 22 abuts against the third sub-shell 13, that is, the third sub-shell 13 constitutes part of the inner wall of the first sub-channel 10c1.

[0112] It can be understood that in this embodiment, the elastic reset member 22 is a compression spring.

[0113] Here, the inner side of the annular groove 21a forms a first guide column 21b, and the outer side wall of the first guide column 21b is the side wall of the radial inner side of the annular groove 21a. One end of the elastic reset member 22 is sleeved on the first guide column 21b, which can facilitate the installation of the elastic reset member 22 on the pressure relief valve 21, and also can guide the elastic deformation direction of the elastic reset member 22, reduce the probability of the elastic reset member 22 swinging in the radial direction, and the reliability of the elastic reset member 22 is higher.

[0114] The side wall of the radial outer side of the annular groove 21a can also guide the elastic deformation direction of the elastic reset member 22 to a certain extent, and can also reduce the risk of the elastic reset member 22 swinging in the radial direction.

[0115] Further, please refer to Figure 4The inner wall of the first sub-channel 10c1 is protruded to form a second guide column 13b towards the pressure relief valve 21, and the other end of the elastic return member 22 is sleeved on the second guide column 13b. The second guide column 13b has similar effect as the first guide column 21b, and will not be described herein again.

[0116] It can be understood that the first guide column 21b and the second guide column 13b cooperate, and both ends of the elastic return member 22 have high stability, thereby further improving the reliability of the pressure relief assembly 20.

[0117] In an embodiment, referring to Figures 2 to 4 , the pressure relief channel 10c further comprises a second sub-channel 10c3 in communication with the liquid inlet cavity 10a. The second sub-channel 10c3 is in butt joint with the first sub-channel 10c1 along the axial direction of the pressure relief channel 10c and is in communication through the overflow port 10c2. In the first position, at least part of the pressure relief valve 21 extends into the second sub-channel 10c3 and sealingly cooperates with the side wall of the second sub-channel 10c3.

[0118] In this embodiment, at least two seals are formed between the pressure relief valve 21 and the side wall of the pressure relief channel 10c. The first seal is the abutting seal between the annular end face 112c and the pressure relief valve 21, and the second seal is the seal between the pressure relief valve 21 and the side wall of the second sub-channel 10c3. Thus, in the first position, the pressure relief valve 21 has better blocking effect on the pressure relief channel 10c, which is conducive to reducing the possibility of condensed liquid flowing out through the pressure relief channel 10c, and the pressure at the outlet of the liquid outlet channel 13a is higher, and the condensed liquid sprayed out through the outlet of the liquid outlet channel 13a is more likely to form a water mist surface.

[0119] In an embodiment, referring to Figures 2 to 4 , Figure 7 , the pressure relief assembly 20 further comprises a sealing member 23. In the first position, the sealing member 23 is sealingly clamped between the side wall of the second sub-channel 10c3 and the pressure relief valve 21, and the sealing member 23 is connected with the side wall of the second sub-channel 10c3 or the pressure relief valve 21.

[0120] The shape of the sealing member 23 is not limited. For example, it can be a sealing ring or the like.

[0121] The material of the sealing member 23 is not limited. For example, it can be rubber, silicone or the like.

[0122] In this embodiment, by providing the sealing member 23, the sealing effect between the pressure relief valve 21 and the second sub-channel 10c3 can be improved.

[0123] In the first position, the sealing member 23 can be in interference fit with the side wall of the second sub-channel 10c3, which is conducive to further improving the sealing effect between the pressure relief valve 21 and the second sub-channel 10c3.

[0124] In some other embodiments, the sealing member 23 can also be arranged at the abutting position of the annular end face 112c and the pressure relief valve 21, i.e., the sealing member 23 is arranged between the annular end face 112c and the pressure relief valve 21 to seal, which is conducive to improving the sealing effect between the annular end face 112c and the pressure relief valve 21.

[0125] In an embodiment, as shown in Figure 7 , the outer side wall of the pressure relief valve 21 is provided with a mounting groove 21c, and the sealing member 23 is sleeved in the mounting groove 21c.

[0126] It can be understood that in the embodiment, the sealing member 23 is arranged on the pressure relief valve 21, i.e., when the pressure relief valve 21 moves linearly between the first position and the second position, the sealing member 23 also linearly displaces.

[0127] Here, the sealing member 23 is sleeved on the pressure relief valve 21, and since the sealing member 23 itself has a certain elasticity, the sealing member 23 adopts the sleeved mounting structure, which is conducive to improving the stability of the installation.

[0128] The mounting groove 21c can limit the displacement of the sealing member 23 in the axial direction of the pressure relief valve 21, so that the interference sealing fit between the sealing member 23 and the side wall of the second sub-channel 10c3 can be achieved.

[0129] In some embodiments, as shown in Figure 2 , the pressure relief channel 10c has a pressure relief port 10c4, and the axial direction of the pressure relief port 10c4 intersects the height direction of the condenser.

[0130] The condensed liquid sprayed through the pressure relief port 10c4 flows in a parabolic curve under the action of gravity.

[0131] In this way, the initial flow velocity of the condensed liquid sprayed through the pressure relief port 10c4 has a smaller component in the direction of gravity, and it takes a longer time for the condensed liquid to be sprayed from the outlet 13c and flow to the bottom of the condensing channel 10b, so that the condensed liquid has a longer time to exchange heat with the wet hot air flow, thereby improving the dehumidification effect of the condenser.

[0132] It should be noted that the angle at which the pressure relief port 10c4 intersects the height direction of the condenser is not limited.

[0133] Exemplarily, as shown in Figure 2, the pressure relief port 10c4 is orthogonal to the height direction of the condenser, so that the initial velocity of the condensed liquid sprayed through the pressure relief port 10c4 in the direction of gravity is zero, thereby being able to increase the flow time of the condensed liquid sprayed through the pressure relief port 10c4 in the condensing channel 10b as much as possible. In addition, this part of the condensed liquid also does not have an initial velocity in the upward direction of the height direction of the condenser, thereby being able to avoid this part of the condensed liquid from entering the heating channel, and the heat generated by the heater can be more used for heating the airflow, thereby being beneficial to improve the drying effect of the clothes treatment equipment.

[0134] In some embodiments, referring to Figure 2 and Figure 5 , the inner wall of the condensing channel 10b is provided with a guide rib 111a, the guide rib 111a extends in the height direction of the condenser, and the pressure relief port 10c4 is directed towards the guide rib 111a, and the guide rib 111a is used to guide the flow of the condensed liquid sprayed through the pressure relief port 10c.

[0135] In this way, the condensed liquid sprayed through the pressure relief port 10c4 flows along the guide rib 111a, thereby being beneficial to increase the length of the flow path and the flow time of this part of the condensed liquid in the condensing channel 10b, and thus increasing the heat exchange time of this part of the condensed liquid with the wet hot airflow, thereby being beneficial to improve the condensing effect of the condenser.
