[0037] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the solutions of the present application will be further described. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0038] In the following description, many specific details are set forth in order to fully understand the present application, but the present application can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some of the embodiments of the present application, not all the embodiments.

[0039] As Figures 1 to 4 ​As shown, the embodiments of the present application provide a clothes processing apparatus with a drying function, which can be a clothes dryer or a washer-dryer. The clothes dryer refers to an apparatus with a drying function, and the washer-dryer refers to an apparatus integrating a drying function and a washing function. At this time, the clothes processing apparatus has a clothes containing drum that can be used for washing and drying. The washing can include cleaning and dehydration.

[0040] Specifically, the clothes processing apparatus includes a clothes containing drum 1, a capacitance detection assembly 2, and a wireless power transmission assembly 3. The clothes containing drum 1 has a clothes containing chamber la. At least a part of the capacitance detection assembly 2 is arranged in the clothes containing chamber la, and the capacitance detection assembly 2 is arranged in the clothes containing drum 1. The wireless power transmission assembly 3 includes a transmitting coil 31 and a receiving coil 32. The receiving coil 32 is arranged on the clothes containing drum 1 and connected to the capacitance detection assembly 2 through a connecting wire harness 4 that passes through the clothes containing drum 1. The receiving coil 32 is used to receive the electric energy transmitted by the transmitting coil 31.

[0041] Understandably, the receiving coil 32 is arranged on the clothes containing drum 1 and connected to the capacitance detection assembly 2 through the connecting wire harness 4 that passes through the clothes containing drum 1. In this way, the receiving coil 32 receives the electric energy transmitted by the transmitting coil 31 and supplies power to the capacitance detection assembly 2, so that the transmitting coil 31 and the receiving coil 32 can realize contactless electric energy transmission. Moreover, the connecting wire harness 4 passes through the clothes containing drum 1 and not the support shaft at the rear end of the clothes containing drum 1 in the axial direction, so as to avoid affecting the structural strength of the support shaft and prolong the service life of the support shaft. Moreover, the drying degree of the clothes can be determined through the detection of the capacitance by the capacitance detection assembly 2, which is beneficial to improve the drying effect of the clothes.

[0042] Exemplarily, the energy is transmitted between the transmitting coil 31 and the receiving coil 32 through a magnetic field. For example, the transmitting coil 31 can generate a varying magnetic field, and the receiving coil 32 can generate an electric current through magnetic induction, so as to realize the transmission of electric energy.

[0043] The rotation axis of the clothes containing drum 1 can extend in the horizontal direction. At this time, the clothes processing apparatus can be a drum-type clothes processing apparatus. For example, the rotation axis of the clothes containing drum 1 extends in the horizontal direction. During the rotation of the clothes containing drum 1, the clothes are moved from the lower side to the upper side. Under the action of gravity, the clothes fall from the upper side to the lower side. In this way, the clothes are dispersed, thrown and changed in posture under the joint action of the clothes containing drum 1 and gravity.

[0044] In addition, the clothes containing drum 1 is substantially in the form of a hollow cylinder and can be a single-cylinder structure, that is, the clothes processing apparatus has only the clothes containing drum 1. Alternatively, the clothes containing drum 1 can be sleeved with an outer drum, so that the clothes processing apparatus has two cylinder bodies. In addition, the clothes containing drum 1 can be made of metal, such as stainless steel.

[0045] It should be noted that, in one case, the clothes containing drum 1 is arranged in the clothes processing apparatus as shown in the accompanying drawings.Figure 1 The aforementioned clothes-holding tube 1 has a support shaft 6 at its rear end along its axial direction, which rotates synchronously with the clothes-holding tube 1. The receiving coil 32 is arranged around the support shaft 6. That is, the receiving coil 32 has a ring structure. Although the receiving coil 32 is arranged around the support shaft 6, the connecting wire harness 4 between the receiving coil 32 and the capacitance detection component 2 does not pass through the support shaft 6, thus reducing the impact on the support shaft 6.

[0046] In another scenario, the clothes-holding tube 1 is rotatably supported at both its front and rear ends along its axial direction by multiple support components. The rear end of the clothes-holding tube 1 is not connected to any other structure. In this case, the receiving coil does not require any obstacle avoidance design and can be designed as a non-ring structure. This reduces the space occupied by the receiving coil while maintaining the same transmission efficiency, facilitating the arrangement of the receiving coil and / or transmitting coil. Furthermore, it increases the transmission efficiency of the receiving coil while maintaining the same space. The support components include at least two support wheels, with the front and rear ends of the clothes-holding tube 1 supported by at least two support wheels along its axial direction.

[0047] Among them, a ring structure is a structure with a central hole, meaning that the ring structure itself forms a central hole. In this case, the ring structure has an inner edge and an outer edge. The inner edge can be circular, elliptical, or polygonal, and the outer edge can also be circular, elliptical, or polygonal, such as a circular ring structure or a square ring structure. A non-ring structure refers to a structure without a central hole, that is, it only has an outer edge and no inner edge. In this case, the outer edge can be circular, elliptical, or polygonal, such as a square structure, a triangular structure, or a circular structure.

[0048] In some embodiments, the garment processing device further includes a bracket (not shown), on which a receiving coil 32 is disposed, and the bracket can be mounted on the garment container 1.

[0049] By setting up a bracket, not only can the receiving coil 32 be fixed, facilitating its installation, but the bracket can also separate the receiving coil 32 from the clothes container 1 by a certain distance, preventing the receiving coil 32 from heating the clothes container 1 when there is magnetic leakage. Of course, the receiving coil 32 can also be directly installed on the clothes container 1.

[0050] Furthermore, the aforementioned garment processing equipment also includes a magnetic shielding layer (not shown in the figure), which is disposed between the receiving coil 32 and the garment holding tube 1.

[0051] Understandably, by setting a magnetic shielding layer, the receiving coil 32 and the clothes container 1 can be separated, preventing the receiving coil 32 from heating the clothes container 1 when it leaks magnetic flux, thus affecting the energy transfer efficiency.

[0052] The projection of the receiving coil 32 on the drum 1 is located within the projection range of the magnetic shielding layer on the drum 1, so that the magnetic shielding layer can completely separate the receiving coil 32 and the drum 1.

[0053] The magnetic shielding layer can be arranged on the bracket or directly arranged on the drum 1, and can shield the magnetic leakage of the receiving coil 32.

[0054] With reference to Figure 1 The laundry treating apparatus further comprises a cabinet 7, the drum 1 is rotatably arranged in the cabinet 7, the receiving coil 32 is arranged at the rear end of the drum 1, and the transmitting coil 31 is arranged on the cabinet 7 and located at the rear of the drum 1.

[0055] Understandably, the receiving coil 32 rotates with the drum 1, and the transmitting coil 31 is arranged on the cabinet 7 and remains stationary, so that the receiving coil 32 rotates relative to the transmitting coil 31.

[0056] Further, at least part of the receiving coil 32 is arranged opposite the transmitting coil 31. Understandably, the centers of the receiving coil 32 and the transmitting coil 31 can both be located on the rotation axis of the drum 1, at which time the receiving coil 32 and the transmitting coil 31 are arranged opposite each other. Alternatively, the receiving coil 32 and the transmitting coil 31 can also be staggered relative to each other, for example, the center of the transmitting coil 31 is located on the rotation axis of the drum 1, and the center line passing through the center of the receiving coil 32 is parallel to the rotation axis of the drum 1. For another example, the center of the receiving coil 32 is located on the rotation axis of the drum 1, and the center line passing through the center of the transmitting coil 31 is parallel to the rotation axis of the drum 1.

[0057] Preferably, the centers of the receiving coil 32 and the transmitting coil 31 are both located on the rotation axis of the drum 1. In this way, during the rotation of the receiving coil 32 with the drum 1, the relative positions of the receiving coil 32 and the transmitting coil 31 remain unchanged, thereby ensuring that the receiving coil 32 and the transmitting coil 31 can stably transmit electric energy.

[0058] In some embodiments, with reference to Figure 1 and Figure 4 The laundry treating apparatus further comprises a lifting rib 5, the lifting rib 5 is arranged on the drum 1 and located in the clothes containing chamber 1a of the drum 1, and the capacitive detection assembly 2 is mounted on the lifting rib 5.

[0059] Understandably, the clothes containing chamber 1a is used for placing clothes, the drum 1 can rotate, the lifting rib 5 can contact the clothes in the clothes containing chamber 1a and drive the clothes to rotate with the drum 1. For example, the clothes move upward under the action of the lifting rib 5, and then move downward under the action of gravity and / or centrifugal force, so that the clothes continuously change posture in the clothes containing chamber 1a.

[0060] Further, the reinforcing rib 5 has a receiving groove 51a, and the capacitive detection assembly 2 is arranged in the receiving groove 51a.

[0061] Specifically, the receiving groove 51a has two opposite side walls, and the capacitive detection assembly 2 includes a first electrode 21 and a second electrode 22, and the first electrode 21 and the second electrode 22 are arranged on the two side walls respectively. In this way, an electric field is formed between the first electrode 21 and the second electrode 22, so that the capacitive parameter in the clothes containing chamber 1a can be obtained, and the capacitive parameter changes with the change of the humidity of the clothes, so that the clothes treatment apparatus can calculate the humidity of the clothes according to the capacitive parameter, so as to obtain the dryness information of the clothes. Further, through the dryness information of the clothes, the clothes treatment apparatus can accurately determine the dryness of the clothes and stop running, so as to ensure that the clothes are fully dried when the clothes treatment apparatus stops running, and improve the drying effect of the clothes.

[0062] It should be noted that the reinforcing rib 5 is provided with a heat dissipation hole 513a. The heat dissipation hole 513a can facilitate heat dissipation of the capacitive detection assembly 2. When the reinforcing rib 5 is provided with the heat dissipation hole 513a, the clothes treatment apparatus is a clothes dryer. When the reinforcing rib is not provided with the heat dissipation hole, the clothes treatment apparatus can be a clothes dryer or a washer-dryer.

[0063] In addition, the clothes treatment apparatus further includes a control board (not shown in the figure) arranged in the receiving groove 51a, and the connection wire harness 4 is connected to the receiving coil 32 and the control board, and the control board is connected to the capacitive detection assembly 2.

[0064] The connection wire harness 4 can transmit electrical signals, and the control board can control the on-off of power supply, such as conducting or cutting off the transmission of electrical energy between the receiving coil 32 and the capacitive detection assembly 2, that is, controlling the start and stop of the capacitive detection assembly 2. The control board is arranged in the receiving groove 51a of the reinforcing rib 5, which is convenient for electrical connection between the control board and the capacitive detection assembly 2.

[0065] The control board can include an MCU, i.e. a micro controller unit. It can be used to realize input functions such as signal acquisition and processing, and output functions such as issuing instructions to control the operation of the actuator.

[0066] Understandably, the receiving coil 32, the control board, the connection wire harness 4 and the capacitive detection assembly 2 rotate synchronously with the clothes containing drum 1, so that the rotation of the clothes containing drum 1 will not cause the connection wire harness 4 to be entangled.

[0067] Furthermore, the clothes-holding tube 1 has a wiring hole for the connecting wire harness 4 to pass through, and the aforementioned lifting rib 5 covers the wiring hole. In this way, one end of the connecting wire harness 4 is connected to the receiving coil 32, and the other end passes through the wiring hole into the receiving groove 51a. The lifting rib 5 covers the wiring hole, which can prevent the connecting wire harness 4 from being exposed inside or outside the clothes-holding chamber 1a, thereby preventing the clothes from contacting the connecting wire harness 4.

[0068] In addition, the aforementioned connecting harness 4 is sealed through the wiring hole, for example by sealing rings, sealant or other sealing structures to seal the gap between the cable and the wiring hole, thereby preventing water or air leakage from the wiring hole when the garment processing equipment is a washer-dryer combo.

[0069] Specifically, refer to Figure 2 The aforementioned clothes container 1 includes a connected body 11 and a rear end cover 12. The front side of the body 11 has a clothes inlet, and the rear end cover closes the rear opening of the body 11. The rear end cover 12 has the aforementioned wiring hole, and the receiving coil 32 is disposed on the rear end cover 12 and located outside the clothes container 1a. The aforementioned lifting rib 5 is disposed on the body 11 and extends to the rear end cover 12 to cover the aforementioned wiring hole.

[0070] For example, refer to Figure 3 and Figure 4 The lifting rib 5 includes a main body 51 and an extension 52 connected to the main body 51. The main body 51 has a receiving groove 51a, and the extension 52 covers the wiring hole.

[0071] The extension 52 is provided with a cable routing cavity through which the connecting wire harness 4 passes, and the rearward-facing surface of the extension 52 is in contact with the rear surface of the garment chamber 1a, that is, in contact with the side surface of the rear end cover 12 facing the garment chamber 1a. The cable routing cavity can be sealed by the rear surface of the garment chamber 1a to prevent water or lint from entering the cable routing cavity.

[0072] The main body 51 includes two side plates 511, a top plate 512, and an end plate 513. The two side plates 511 are spaced apart circumferentially along the clothes-holding tube 1, and the bottom ends of both side plates 511 are connected to the peripheral side wall of the clothes-holding tube 1. The top plate 512 is connected to the top ends of the two side plates 511, and the end plate 513 is connected to the front ends of the two side plates 511. The top plate 512, end plate 513, and two side plates 511 together define a receiving groove 51a. The rear ends of the two side plates 511 are connected to the extension 52.

[0073] The first electrode 21 and the second electrode 22 of the capacitance detection component 2 are respectively disposed on the two side plates 511. The end plate 513 is provided with the aforementioned heat dissipation hole 513a.

[0074] It should be noted that the side plate 511 and the end plate 513 are both sealingly connected to the circumferential wall of the clothes containing drum 1 to ensure the sealing of the containing groove 51a.

[0075] Further, the lifting rib 5 further comprises a reinforcing portion 53 arranged in the containing groove 51a to improve the structural strength of the lifting rib 5. The reinforcing portion 53 comprises a partition plate and a reinforcing rib plate arranged in the containing groove 51a.

[0076] In some other embodiments, the capacitive detection assembly can also comprise a first electrode member and a second electrode member. The first electrode member is configured as a lifting rib arranged on the clothes containing drum and located in the clothes containing chamber. The second electrode member is arranged on the inner wall of the clothes containing drum or on the front support of the clothes treating apparatus.

[0077] It can be understood that the first electrode member is configured as a lifting rib in the clothes containing drum, so that an additional lifting rib arranged in the clothes containing drum can be omitted, and the structure can be simplified and the installation process can be simplified. The second electrode member can be arranged on the inner wall of the clothes containing drum, so that the capacitive detection assembly is located entirely in the clothes containing chamber. An electric field is formed between the first electrode member and the second electrode member, and the humidity of the clothes is calculated by obtaining the capacitance parameter in the clothes containing chamber, so that the dryness information of the clothes is obtained.

[0078] In addition, the second electrode member can also be arranged outside the clothes containing drum, such as on the front support of the clothes treating apparatus. In this way, part of the capacitive detection assembly is located in the clothes containing chamber, and part of the capacitive detection assembly is located outside the clothes containing chamber. Similarly, an electric field is formed between the first electrode member and the second electrode member, and the humidity of the clothes is calculated by obtaining the capacitance parameter in the clothes containing chamber, so that the dryness information of the clothes is obtained. Of course, the second electrode member is not limited to being arranged on the front support, but can also be arranged at other positions of the clothes treating apparatus, as long as an electric field can be formed between the first electrode member and the second electrode member to realize the detection of the dryness information of the clothes.

[0079] The clothes treating apparatus comprises a circulating air duct. The rear side wall of the clothes containing drum 1 is formed with at least one air inlet communicating with the clothes containing chamber 1a. The circulating air duct communicates the air inlet with an air outlet of the clothes containing chamber 1a. For example, the rear side wall of the clothes containing drum 1 is formed with an air inlet. The circulating air duct is used to provide a circulating air flow repeatedly flowing through the clothes containing chamber 1a. The air flow can enter the clothes containing chamber 1a through the air inlet, and the air flow in the clothes containing chamber 1a can enter the circulating air duct through the air outlet. The air flow can circulate between the circulating air duct and the clothes containing chamber 1a.

[0080] It can be understood that the number of air inlets can be one or more, for example, two, three, four, or five, and the like.

[0081] In an embodiment, the laundry treatment apparatus includes a wind cover. The above-mentioned base is located in the cabinet 7 and below the clothes containing drum 1, and the rear side wall of the cabinet 7 is formed with an air return opening and an air supply opening in communication with the air inlet opening, the height of the air return opening being lower than that of the air supply opening. The base is formed with a heat exchange channel, both ends of the heat exchange channel being in communication with the air outlet opening and the air return opening, respectively. The wind cover covers the periphery of the air supply opening and the air return opening, and cooperates with the rear side wall of the cabinet 7 to define an air supply channel. The heat exchange channel and the air supply channel jointly constitute a circulating air duct. The heat exchange channel is located upstream of the air supply channel along the flow direction of the air flow in the circulating air duct, and the air flow sequentially flows through the air outlet opening, the heat exchange channel, the air return opening, the air supply channel, the air supply opening and the air inlet opening. The cabinet 7 can be substantially hexahedral, for example, a square or cuboid.

[0082] The number of air supply openings is not limited, and the air supply openings can be one or more, for example, two, three, four or five, etc.

[0083] Further, the laundry treatment apparatus includes a heat exchange assembly located in the heat exchange channel, which is used to exchange heat with the air flow in the heat exchange channel, thereby dehumidifying and heating. The humid and hot air flow in the clothes containing chamber 1a can enter the heat exchange channel through the air outlet opening, and is converted into dry and hot air flow after heat and mass exchange with the heat exchange assembly, and then enters the air supply channel through the air return opening, and then returns to the clothes containing chamber 1a through the air supply opening and the air inlet opening.

[0084] The above-mentioned heat exchange assembly includes a condenser and an evaporator, and the laundry treatment apparatus further includes a compressor and a throttling device, and the compressor, the condenser, the throttling device and the evaporator are connected by pipelines to constitute a heat pump system, and the refrigerant can circulate in the heat pump system. The air flow in the circulating air duct exchanges heat with the refrigerant in the evaporator and the condenser to form dry and hot air flow. The evaporator is used to cool and dehumidify the humid and hot air flow from the clothes containing chamber 1a into dry and cold air flow; and the condenser heats the dry and cold air flow into dry and hot air flow to return to the clothes containing chamber 1a.

[0085] 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 discharge; the high-pressure state refrigerant discharged into the condenser, and the refrigerant in the condenser transfers heat to the air flow to condense into high-pressure liquid; the high-pressure liquid refrigerant flows through the throttling device to reduce pressure, and then becomes a low-pressure low-temperature gas-liquid two-phase mixture into the evaporator; the refrigerant in the evaporator absorbs the heat of the air flow to become low-pressure gas; the low-pressure gas refrigerant is sucked into the compressor again; thus, the heat exchange is realized through repeated circulation. That is, the evaporator is used to cool and dehumidify the humid and hot air flow from the clothes containing chamber 1a into dry and cold air flow, and the condenser heats the dry and cold air flow into dry and hot air flow to return to the clothes containing chamber 1a, and the dry and hot air flow returning to the clothes containing chamber 1a contacts the humid clothes again to form humid and hot air flow again, completing a drying cycle. Through repeated operation of the drying cycle, the circulating air flow is continuously provided to the clothes containing chamber 1a to dry the clothes.

[0086] Exemplarily, the evaporator and the condenser can both be finned tube heat exchangers.

[0087] Exemplarily, the throttling device includes, but is not limited to, an electronic expansion valve, etc.

[0088] Further, the clothes treating apparatus includes a fan wheel for driving the airflow. Exemplarily, the fan wheel is located in the heat exchange channel and between the heat exchange assembly and the return air inlet. During the process of drying the clothes, the fan wheel is used to drive the airflow flowing through the clothes to sequentially flow through the evaporator and the condenser, and then blow to the clothes to form the circulating air. The fan wheel can accelerate the airflow and improve the drying efficiency.
