[0063] To make the objectives, technical solutions and advantages of the present application clearer, the following will further describe in detail the embodiments of the present application with reference to the accompanying drawings.

[0064] When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present application. On the contrary, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0065] A laundry treatment device (such as a dryer) includes a cabinet and a drum disposed within the cabinet. When the laundry treatment device is in operation, in order to dry the laundry within the drum more evenly, the drum is capable of rotating relative to the cabinet. When the laundry within the drum rotates with the drum to near the top of the drum, it will automatically fall to the bottom of the drum, and then rotate upward with the drum again, realizing the turning of the laundry, and repeating the cycle to achieve the purpose of drying the laundry more evenly.

[0066] In the related art, some electrical components (such as a humidity sensor) are provided on the drum. These electrical components require electrical energy supply to ensure smooth operation. However, since the drum rotates relative to the cabinet when the laundry treatment device is in operation, it is not conducive to the electrical components receiving external power supply.

[0067] Please refer to Figures 1 to 4 , Figure 1 which is a partial exploded structural schematic diagram of the laundry treatment device provided by the embodiment of the present application. Figures 2 to 4 Respectively Figure 1 are partial structural schematic diagrams of the laundry treatment device shown, in combination with Figures 1 to 4 , the laundry treatment device 1 includes a cabinet 10, a laundry tub 20 and a wireless power transmission structure 30.

[0068] Among them, the laundry tub 20 is used to hold laundry, etc. The laundry tub 20 is located within the cabinet 10 and is rotatably connected to the cabinet 10, and is used to drive the laundry held therein to rotate when rotating relative to the cabinet 10 to achieve the purpose of treating the laundry. The wireless power transmission structure 30 is located within the cabinet 10 and includes two wireless power transmission components 31 that cooperate with each other. The two wireless power transmission components 31 are respectively fixed relative to the cabinet 10 and the laundry tub 20. The two wireless power transmission components 31 can transmit energy wirelessly. In this way, the wireless power transmission component 31 fixed relative to the laundry tub 20 can supply power to the electrical component 52 without being connected to an external power source by a conducting wire, avoiding interference between the conducting wire and the laundry tub 20 during the rotation process.

[0069] In some embodiments, the two wireless power transmission components 31 include a transmitting wireless power transmission component 31a and a receiving wireless power transmission component 31b. The transmitting wireless power transmission component 31a is fixed relative to the cabinet 10, and the receiving wireless power transmission component 31b is fixed relative to the laundry tub 20. The receiving wireless power transmission component 31b can receive the energy transmitted by the transmitting wireless power transmission component 31a wirelessly. In this way, the receiving wireless power transmission component 31b can supply power to the electrical component 52 without being connected to an external power source by a conducting wire, avoiding interference between the conducting wire and the laundry tub 20 during the rotation process.

[0070] The above-mentioned transmitting wireless power transmission component 31a is fixed relative to the box body 10. The transmitting wireless power transmission component 31a can be installed on the box body 10, or it can be a structural member installed on the box body 10, such as a windshield installed on the box body 10, and no limitation is made thereto. The above-mentioned receiving wireless power transmission component 31b is fixed relative to the laundry tub 20. The receiving wireless power transmission component 31b can be installed on the laundry tub 20, or it can be a structural member installed on the laundry tub 20, and no limitation is made thereto.

[0071] Referring to Figures 4 to 10 , in which, Figures 5 to 7 are respectively the front view structural schematic diagram, the exploded structural schematic diagram and the partial sectional structural schematic diagram of the transmitting wireless power transmission component 31a, Figures 8 to 10 are respectively the front view structural schematic diagram, the exploded structural schematic diagram and the partial sectional structural schematic diagram of the receiving wireless power transmission component 31b. Combining Figures 4 to 10 , the wireless power transmission component 31 includes a coil 311. At least one wireless power transmission component 31 further includes a magnetic isolation member 312. A magnetic isolation groove 3121 is formed on one side of the magnetic isolation member 312 facing the other wireless power transmission component 31. The coil 311 is located in the magnetic isolation groove 3121 and is connected to the magnetic isolation member 312. It should be noted that it can be designed that one of the wireless power transmission components 31 includes the magnetic isolation member 312, or it can be designed that both of the wireless power transmission components 31 include the magnetic isolation member 312, and no limitation is made thereto.

[0072] Among them, the two wireless power transmission components 31 can transmit electromagnetic energy in the form of an alternating magnetic field to realize wireless energy transmission between the two. For example, the coil 311 of the receiving wireless power transmission component 31b can receive the electromagnetic energy transmitted by the transmitting wireless power transmission component 31a in the form of an alternating magnetic field, generate a current through electromagnetic induction, and realize wireless energy transmission between the transmitting wireless power transmission component 31a and the receiving wireless power transmission component 31b. Among them, the coil 311 of the transmitting wireless power transmission component 31a can be used to generate an alternating magnetic field.

[0073] In the embodiment of the present application, when the laundry tub 20 rotates relative to the box body 10, the transmitting wireless power transmission component 31a and the receiving wireless power transmission component 31b can still provide electric energy for electrical components such as the electrical component 52 to meet the power consumption requirements.

[0074] Among them, the connection between the coil 311 and the magnetic isolation member 312 can improve the eddy current influence caused by the magnetic field generated during the magnetoelectric conversion of the two wireless power transmission components 31 on other devices (such as metal parts) outside the wireless power transmission structure 30.

[0075] In some embodiments, the coil 311 is located within the magnetic isolation groove 3121 of the magnetic isolation member 312, and the inner wall of the magnetic isolation groove 3121 can be used to constrain the magnetic field lines generated during the magnetoelectric conversion of the wireless energy transmission structure 30. Specifically, the magnetic field lines can be constrained from the circumferential side of the coil 311 and the side thereof facing away from the other wireless energy transmission component 31, which can constrain the magnetic field lines to a greater extent and can better improve the eddy current effect caused by the magnetic field lines on other devices outside the wireless energy transmission structure 30.

[0076] Moreover, the magnetic isolation member 312 can also be used to achieve the magnetic focusing effect of the wireless energy transmission component 31, so that the magnetic field is concentrated between the coil 311 of this coil 311 and the coil 311 of the other wireless energy transmission component 31, thereby improving the wireless charging efficiency.

[0077] In some embodiments, the coil 311 can be generally annular. For example, the coil 311 can be an annular structure provided on the periphery of a rotating shaft (not shown in the figure). Herein, the rotating shaft can be arranged outside the laundry tub 20 and connected to the laundry tub 20, and the laundry tub 20 can rotate relative to the cabinet 10 around the rotating shaft. Among them, the rotating shaft can be a metal part, and the above-mentioned designed magnetic isolation member 312 can improve the eddy current effect caused by the magnetic field lines generated during the magnetoelectric conversion of the wireless energy transmission structure 30 on the rotating shaft.

[0078] In some embodiments, the magnetic isolation member 312 includes an end plate magnetic isolation portion 3122, an inner ring magnetic isolation portion 3123, and an outer ring magnetic isolation portion 3124. The inner ring magnetic isolation portion 3123 is connected to the end plate magnetic isolation portion 3122. The outer ring magnetic isolation portion 3124 is connected to the end plate magnetic isolation portion 3122 and is arranged on the periphery of the inner ring magnetic isolation portion 3123. The outer ring magnetic isolation portion 3124 is spaced apart from the inner ring magnetic isolation portion 3123, and a magnetic isolation groove 3121 is formed between the outer ring magnetic isolation portion 3124, the inner ring magnetic isolation portion 3123, and the end plate magnetic isolation portion 3122.

[0079] In this way, the coil 311 is located within the magnetic isolation groove 3121. The end plate magnetic isolation portion 3122 can constrain the magnetic field lines on the side of the coil 311 facing away from the other wireless energy transmission component 31. The inner ring magnetic isolation portion 3123 can constrain the magnetic field lines on the inner circumferential side of the coil 311. The outer ring magnetic isolation portion 3124 can constrain the magnetic field lines on the outer circumferential side of the coil 311, which can constrain the magnetic field lines to a greater extent and can better improve the eddy current effect caused by the magnetic field lines on other devices outside the wireless energy transmission structure 30.

[0080] In some embodiments, the end plate magnetic isolation portion 3122, the inner ring magnetic isolation portion 3123, and the outer ring magnetic isolation portion 3124 are an integrally formed structure to improve the structural stability of the magnetic isolation member 312 and save the assembly process.

[0081] Among them, the magnetic isolation member 312 is made of a magnetic isolation material. For example, the manufacturing materials of the magnetic isolation member 312 include, but are not limited to, ferrite, nanocrystalline, non-nanocrystalline, soft magnetic body, and the like. Among them, the soft magnetic body is similar to ferrite powder added to rubber or plastic to form a magnetic isolation effect.

[0082] Among them, the connection between the coil 311 and the magnetic isolation member 312 can be an adhesive connection, a snap connection, a locking member connection, and the like.

[0083] In some embodiments, the wireless power transmission component 31 further includes a first encapsulation layer 313. The first encapsulation layer 313 is located in the magnetic isolation groove 3121 and connects the coil 311 and the magnetic isolation member 312. Among them, the first encapsulation layer 313 can be a glue layer. The connection between the coil 311 and the magnetic isolation member 312 can be realized by potting. The operation is convenient and the glue layer can be adaptively deformed according to the shapes of the coil 311 and the magnetic isolation member 312, which can improve the connection reliability between the coil 311 and the magnetic isolation member 312.

[0084] Specifically, when assembling the coil 311 and the magnetic isolation member 312, potting can be first performed in the magnetic isolation groove 3121 of the magnetic isolation member 312, and then the coil 311 can be placed in the magnetic isolation groove 3121; alternatively, the coil 311 can be first placed in the magnetic isolation groove 3121, and then potting is performed in the magnetic isolation groove 3121. The present application embodiment does not limit the sequence of potting to form the first encapsulation layer 313.

[0085] In some embodiments, the first encapsulation layer 313 includes at least one of a first encapsulation portion 3131, a second encapsulation portion 3132, and a third encapsulation portion 3133. Among them, the first encapsulation portion 3131 is located in the magnetic isolation groove 3121 and connects the bottom wall of the magnetic isolation groove 3121 and the coil 311. The second encapsulation portion 3132 is located in the magnetic isolation groove 3121 and connects the peripheral wall of the magnetic isolation groove 3121 and the coil 311. The third encapsulation portion 3133 is located in the magnetic isolation groove 3121 and on the side of the coil 311 close to another wireless power transmission component 31. The third encapsulation portion 3133 covers the coil 311 and connects the magnetic isolation member 312 and the coil 311.

[0086] The first encapsulation portion 3131, the second encapsulation portion 3132, and the third encapsulation portion 3133 can connect the magnetic isolation member 312 and the coil 311 from different orientations. In actual operation, the first encapsulation layer 313 can be designed to include at least one of the first encapsulation portion 3131, the second encapsulation portion 3132, and the third encapsulation portion 3133 according to actual needs.

[0087] It should be noted that since the third encapsulation part 3133 is located on the side of the coil 311 close to the other wireless power transmission component 31, it can seal the opening of the magnetic isolation groove 3121 and cover the coil 311, which can improve the influence of lint, high temperature and high humidity, etc. on the lifespan of the coil 311 and enhance the reliability of the coil 311.

[0088] In the embodiment of the present application, the first encapsulation layer 313 includes a first encapsulation part 3131, a second encapsulation part 3132 and a third encapsulation part 3133, so that the first encapsulation layer 313 wraps the coil 311 to better improve the influence of lint, high temperature and high humidity, etc. on the lifespan of the coil 311 and enhance the reliability of the coil 311.

[0089] Specifically, when assembling the coil 311 and the magnetic isolation part 312, glue can be first poured into the magnetic isolation groove 3121 of the magnetic isolation part 312, and then the coil 311 is placed into the magnetic isolation groove 3121, so that the bottom wall and the peripheral wall of the coil 311 are both coated with glue, so as to form the first encapsulation part 3131 and the second encapsulation part 3132; then glue is continuously poured into the magnetic isolation groove 3121, so that the side of the coil 311 close to the other wireless power transmission component 31 is also coated with glue, so as to form the third encapsulation part 3133.

[0090] In some embodiments, the wireless power transmission component 31 further includes a mounting shell 314, and the mounting shell 314 is connected to the magnetic isolation part 312. The mounting shell 314 is used to mount and fix the wireless power transmission component 31 relative to the clothes storage barrel 20 or the box body 10. Specifically, the receiving wireless power transmission component 31b is fixed relative to the clothes storage barrel 20 through its mounting shell 314, and the transmitting wireless power transmission component 31a is fixed relative to the box body 10 through its mounting shell 314.

[0091] Since the magnetic isolation part 312 is made of a magnetic isolation material and its structure is relatively brittle, therefore, a separate mounting shell 314 is designed to connect the magnetic isolation part 312 and realize the mounting and fixing of the wireless power transmission component 31 relative to the clothes storage barrel 20 or the box body 10, which is beneficial to improving the stability of the wireless power transmission component 31 mounted and fixed on the clothes storage barrel 20 or the box body 10, and the mounting shell 314 can separate the magnetic isolation part 312 from the clothes storage barrel 20 or the box body 10 to improve the influence of the high temperature of the clothes storage barrel 20 or the box body 10 on the magnetic isolation part 312.

[0092] In some embodiments, the mounting shell 314 can be made of materials such as plastic, metal (such as aluminum), etc., and has characteristics such as high structural strength and high temperature resistance.

[0093] In some embodiments, a mounting groove 3141 is formed on the side of the mounting shell 314 facing the other wireless power transmission component 31, and the magnetic isolation part 312 is located in the mounting groove 3141 and connected to the mounting shell 314, so that the mounting shell 314 can provide a better protection effect for the magnetic isolation part 312.

[0094] In some embodiments, the mounting housing 314 includes an end housing 3143, an inner ring housing 3144, and an outer ring housing 3145. The inner ring housing 3144 is connected to the end housing 3143. The outer ring housing 3145 is connected to the end housing 3143 and is disposed around the inner ring housing 3144. The outer ring housing 3145 is spaced apart from the inner ring housing 3144, and an installation groove 3141 is formed between the outer ring housing 3145, the inner ring housing 3144, and the end housing 3143.

[0095] In some embodiments, the end housing 3143, the inner ring housing 3144, and the outer ring housing 3145 are of an integrally formed structure to improve the structural stability of the mounting housing 314 and save the assembly process.

[0096] In some embodiments, the mounting housing 314 mounts and fixes the wireless power transmission component 31 relative to the laundry tub 20 or the cabinet 10 through at least one of the end housing 3143, the inner ring housing 3144, and the outer ring housing 3145. In some other embodiments, the mounting housing 314 further includes a connection base 3142, and the mounting housing 314 mounts and fixes the wireless power transmission component 31 relative to the laundry tub 20 or the cabinet 10 through the connection base 3142. Wherein, the connection base 3142 may be located outside the outer ring housing 3145 and connected to the outer ring housing 3145, or may be located inside the inner ring housing 3144 and connected to the inner ring housing 3144. The specific setting position of the connection base 3142 can be adaptively adjusted in combination with the internal space layout in the laundry treatment device 1.

[0097] In the embodiments of the present application, refer to Figure 5 and Figure 6 , the connection base 3142 of the transmitting wireless power transmission component 31a is located outside the outer ring housing 3145 and connected to the outer ring housing 3145. Refer to Figure 8 and Figure 9 , the connection base 3142 of the receiving wireless power transmission component 31b is located inside the inner ring housing 3144 and connected to the inner ring housing 3144.

[0098] In some embodiments, the mounting housing 314 includes a plurality of connection bases 3142 spaced circumferentially along the mounting housing 314 to improve the reliability of the mounting and fixing of the wireless power transmission component 31 relative to the laundry tub 20 or the cabinet 10.

[0099] In some embodiments, refer to Figure 7 and Figure 10 , the wireless power transmission component 31 further includes a second encapsulation layer 315. The second encapsulation layer 315 is located in the installation groove 3141 and connects the magnetic isolation member 312 to the mounting housing 314. Wherein, the second encapsulation layer 315 may be an adhesive layer, and the connection between the magnetic isolation member 312 and the mounting housing 314 can be achieved by potting. The operation is convenient, and the adhesive layer can be adaptively deformed according to the shapes of the magnetic isolation member 312 and the mounting housing 314, which can improve the connection reliability between the magnetic isolation member 312 and the mounting housing 314.

[0100] Specifically, when assembling the magnetic isolation member 312 and the mounting shell 314, it is possible to first apply glue in the mounting groove 3141 of the mounting shell 314 and then place the magnetic isolation member 312 into the mounting groove 3141; it is also possible to first place the magnetic isolation member 312 into the mounting groove 3141 and then apply glue into the mounting groove 3141. The embodiment of the present application does not limit the sequence of applying glue to form the second encapsulation layer 315.

[0101] In the embodiment of the present application, in the wireless power transmission assembly 31 (the transmitting wireless power transmission assembly 31a and the receiving wireless power transmission assembly 31b), the coil 311 and the magnetic isolation member 312 are connected through the first encapsulation layer 313, and the magnetic isolation member 312 and the mounting shell 314 are connected through the second encapsulation layer 315, so that the wireless power transmission assembly 31 can form a modular structure, which is conducive to the installation and fixation of the wireless power transmission assembly 31 with the laundry tub 20 or the box body 10.

[0102] In some embodiments, referring to Figure 1 , both the transmitting wireless power transmission assembly 31a and the receiving wireless power transmission assembly 31b are located outside the laundry tub 20 to avoid contact with loads such as clothes in the laundry tub 20 and improve safety.

[0103] In some embodiments, referring to Figure 2 , the box body 10 includes a back plate 11, and the transmitting wireless power transmission assembly 31a is installed on one side of the back plate 11 close to the laundry tub 20.

[0104] In some embodiments, the transmitting wireless power transmission assembly 31a may be located at a position corresponding to the central area of the rear cover 22 on the back plate 11. Among them, the back plate 11 may be a metal part, and the above-designed magnetic isolation member 312 can improve the eddy current influence on the back plate 11 caused by the magnetic lines of force generated during the magnetoelectric conversion of the wireless power transmission structure 30.

[0105] In some embodiments, referring to Figure 3 , the laundry tub 20 includes a tub body 21 and a rear cover 22. The front side of the tub body 21 has a clothing inlet, and the rear cover 22 closes the rear end opening of the tub body 21. The receiving wireless power transmission assembly 31b may be disposed on a side of the rear cover 22 facing away from the tub body 21.

[0106] In some embodiments, the receiving wireless power transmission assembly 31b may be located in the central area of the rear cover 22.

[0107] In some embodiments, along the depth direction of the laundry tub 20, the projections of the transmitting wireless power transmission assembly 31a and the receiving wireless power transmission assembly 31b at least partially overlap. Exemplarily, referring to Figure 4 , the transmitting wireless power transmission assembly 31a is aligned with the receiving wireless power transmission assembly 31b.

[0108] In some embodiments, along the depth direction of the laundry tub 20, the projection of the coil 311 of the wireless power transmitting component 31a and the projection of the coil 311 of the wireless power receiving component 31b at least partially overlap. Exemplarily, the coil 311 of the wireless power transmitting component 31a is aligned with the coil 311 of the wireless power receiving component 31b, so as to increase the electromagnetic energy received by the wireless power receiving component 31b.

[0109] In some embodiments, referring to Figure 11 , Figure 11 is the circuit block diagram of the laundry treatment device provided by the embodiment of the present application. In combination with Figure 11 , the laundry treatment device 1 further includes an electrical component 52 and a first control board 51. The electrical component 52 is fixed relative to the laundry tub 20, and the first control board 51 is fixed relative to the laundry tub 20. The first control board 51 is integrated with a receiving control circuit and an electrical component control circuit. The receiving control circuit is electrically connected to the wireless power receiving component 31b, and the electrical component control circuit is electrically connected to the electrical component 52. In this way, the wireless power receiving component 31b can supply power to the electrical component 52 to maintain the energy required for the operation of the electrical component 52. Among them, the electrical component 52 can be a humidity sensor, etc., which is not limited thereto. The above design integrates the receiving control circuit and the electrical component control circuit on the first control board 51, which is beneficial to reducing the manufacturing cost of the laundry treatment device 1 and saving the assembly process.

[0110] Since the wireless power receiving component 31b, the electrical component 52 and the first control board 51 are all fixed relative to the laundry tub 20 and can move synchronously with the laundry tub 20, there will be no problems such as entanglement of the wiring between the wireless power receiving component 31b and the first control board 51 and the wiring between the electrical component 52 and the first control board 51.

[0111] The above-mentioned electrical component 52 being fixed relative to the laundry tub 20 can be that the electrical component 52 is installed on the laundry tub 20, or that the electrical component 52 is installed on a structural member on the laundry tub 20, which is not limited thereto. The above-mentioned first control board 51 being fixed relative to the laundry tub 20 can be that the first control board 51 is installed on the laundry tub 20, or that the first control board 51 is installed on a structural member on the laundry tub 20, which is not limited thereto.

[0112] In some embodiments, the laundry treatment apparatus 1 further includes a lifting rib 60. The lifting rib 60 is installed in the clothing tub 20 and can actively contact and closely fit the clothing in the clothing tub 20 following the rotation of the clothing tub 20. As the clothing tub 20 rotates, it drives the clothing to perform complex movements together. Specifically, under the push of the lifting rib 60, the clothing experiences a process of slowly rising from the bottom to the top. Subsequently, under the combined action of gravity and centrifugal force, the clothing naturally slides back to the bottom again. This cyclic process of rising and falling not only continuously changes the posture of the clothing in the clothing tub 20 but also ensures that every corner of the clothing can uniformly receive treatments such as washing or drying, thereby achieving the best cleaning or drying effect.

[0113] In some embodiments, an installation cavity (not shown in the figure) is defined between the lifting rib 60 and the clothing tub 20, and the first control board 51 is located in the installation cavity. In this way, the concealment of the first control board 51 can be improved, and the first control board 51 can be prevented from interfering with the clothing in the clothing tub 20.

[0114] In some embodiments, the laundry treatment apparatus 1 further includes a second control board 71. The second control board 71 is fixed relative to the cabinet 10. The second control board 71 integrates a power supply circuit and a transmission control circuit, and the transmission control circuit is electrically connected to the transmission wireless power transfer component 31a. Designing the second control board 71 to integrate a power supply circuit and a transmission control circuit is beneficial to reducing the manufacturing cost of the laundry treatment apparatus 1 and saving the assembly process.

[0115] The above-mentioned second control board 71 being fixed relative to the cabinet 10 can mean that the second control board 71 is installed on the cabinet 10, or that the second control board 71 is installed on a structural member of the cabinet 10, and no limitation is made thereto.

[0116] In some embodiments, the second control board 71 is located outside the cabinet 10 and outside the air duct. It can avoid being affected by high temperature, moisture, etc. inside the laundry treatment apparatus 1 and is convenient for the staff to disassemble, install, and overhaul.

[0117] In some embodiments, the laundry treatment apparatus 1 further includes a driving device. The driving device serves as the power source of the entire apparatus and can be a motor or the like, so that the clothing tub 20 can rotate or swing. This dynamic movement mode not only helps the clothing to uniformly tumble in the tub, improving the uniformity of washing and drying, but also effectively avoids clothing entanglement or local excessive wear, protecting the texture of the clothing.

[0118] In some embodiments, the laundry treating apparatus 1 further includes a heat exchange assembly. A circulation air duct is further formed in the cabinet 50, and the circulation air duct is configured to provide a circulating air flow that repeatedly flows through the drum 20. The heat exchange assembly is configured to exchange heat with the air flow in the circulation air duct, thereby dehumidifying and heating. The humid and hot air flow in the drum 20 can enter the circulation air duct through the air outlet, and after undergoing heat and mass exchange with the heat exchange assembly, it is converted into a dry and hot air flow, and the dry and hot air flow returns to the drum 20.

[0119] In some embodiments, the heat exchange assembly includes a condenser and an evaporator. The laundry treating apparatus 1 further includes a compressor and a throttling device. The compressor, the condenser, the throttling device, and the evaporator are connected by pipes to form a heat pump system, and the refrigerant can circulate within the heat pump system. The air flow in the circulation air duct exchanges heat with the refrigerant in the evaporator and the condenser to form a dry and hot air flow. The evaporator is configured to cool and dehumidify the humid and hot air flow from the drum 20 into a dry and cold air flow; the condenser heats the dry and cold air flow into a dry and hot air flow and returns it to the drum 20.

[0120] The working principle of the heat pump system is as follows: The compressor sucks in low-pressure gaseous refrigerant and compresses it into high-pressure for discharge; the discharged high-pressure refrigerant enters the condenser, and the refrigerant in the condenser transfers heat to the air flow and condenses into a high-pressure liquid; the high-pressure liquid refrigerant flows through the throttling device for throttling and pressure reduction, and then becomes a low-pressure and low-temperature gas-liquid two-phase mixture and enters the evaporator; the refrigerant in the evaporator absorbs the heat of the air flow and becomes low-pressure gaseous; the low-pressure gaseous refrigerant is sucked in by the compressor again; and so on in a repeated cycle to achieve heat exchange. That is to say, the evaporator is configured to cool and dehumidify the humid and hot air flow from the drum 20 to form a dry and cold air flow, the condenser heats the dry and cold air flow into a dry and hot air flow and then returns it to the drum 20, and the dry and hot air flow returning to the drum 20 contacts the wet clothes to form a humid and hot air flow again, completing one drying cycle. By repeatedly operating the drying cycle, a circulating air flow is continuously provided to the drum 20 to dry the clothes.

[0121] Exemplarily, both the evaporator and the condenser can be finned-tube or microchannel heat exchangers.

[0122] Exemplarily, the throttling device includes but is not limited to an electronic expansion valve and the like.

[0123] In one embodiment, the laundry treating apparatus 1 includes a blower wheel, and the blower wheel is configured to drive the air flow to flow. Exemplarily, the blower wheel is located within the circulation air duct and between the heat exchange assembly and the air return opening. During the process of drying clothes, the blower wheel is configured to drive the air flow flowing through the clothes to flow through the evaporator and the condenser in sequence, and then blow towards the clothes to form a circulating air flow. The blower wheel can accelerate the air flow and improve the clothes drying efficiency.
