[0072] In the following description, the terms "first\second\..." are merely to distinguish different objects, and do not mean that there is the same or the relationship between the objects. It should be noted that in the embodiments of the present application, down refers to the direction of the ground, and up is opposite to down; front refers to the direction towards the user, and back is opposite to front; the up-down direction and the front-back direction are perpendicular. In the embodiments of the present application, the "up", "down", "front", "back" orientation or position relationship is based on the orientation or position relationship shown in the drawings. It should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application. The present application will be further described in detail below in conjunction with the drawings and specific embodiments.
[0073] In the related art, the sensor is arranged on a front support of the clothes processing apparatus, and the front support is located at the front side of the clothes containing drum. The sensor is relatively far away from the load such as clothes in the clothes containing cavity, and the problem of inaccurate judgment is prone to occur.
[0074] Please refer to FIGS. 1 to 4 and 13, the embodiment of the application provides a clothes processing apparatus. The clothes processing apparatus comprises a clothes containing drum 1, a lifting rib 2 and an electric conductivity detection device 3. The clothes containing drum 1 has a clothes containing cavity 1a, and the lifting rib 2 is arranged in the clothes containing cavity 1a. At least part of the electric conductivity detection device 3 is arranged on the outer surface of the lifting rib 2.
[0075] The clothes processing apparatus has a drying function, and the clothes processing apparatus can be used to dry clothes. The clothes processing apparatus can be a clothes drying apparatus or a washing and drying integrated apparatus. The clothes drying apparatus refers to an apparatus having a drying function. The washing and drying integrated apparatus refers to an apparatus integrating a drying function and a washing function, and the clothes containing cavity 1a can be used for washing and drying. The washing function can include cleaning and dehydration.
[0076] The clothes containing cavity 1a can be used to place and dry the load such as clothes. The clothes containing drum 1 can rotate, and the lifting rib 2 can contact the clothes in the clothes containing cavity 1a and drive the clothes to rotate together with the clothes containing drum 1. For example, the clothes move upward under the action of the lifting rib 2, and then move downward under the action of gravity and / or centrifugal force, and so on. In this way, the clothes continuously change the posture in the clothes containing cavity 1a.
[0077] The electric conductivity detection device 3 can detect the electric conductivity of the load such as clothes in the clothes containing cavity 1a. The clothes processing apparatus can judge the drying degree according to the electric conductivity detected by the electric conductivity detection device 3. As an example, the principle of the electric conductivity detection device 3 can be that the load in the clothes containing cavity 1a contacts two electrode pieces of the electric conductivity detection device 3, so that the electric conductivity detection circuit is turned on. The resistance values of the loads with different moisture levels are different, that is, the moisture level of the load is related to the electric conductivity, and the drying degree is judged according to the electric conductivity.
[0078] The clothes processing apparatus provided by the embodiment of the application has the electric conductivity detection device 3 arranged on the outer surface of the lifting rib 2. The electric conductivity detection device 3 can contact the load such as clothes in the clothes containing cavity 1a, so as to perceive the drying degree of the clothes at a close distance, and effectively improve the accuracy of judging the drying degree of the clothes in the clothes containing drum 1.
[0079] In an embodiment, the rotation axis of the clothes containing drum 1 can be along the horizontal direction, that is, the clothes processing apparatus can be a drum-type clothes processing apparatus.
[0080] With the rotation axis of the clothes containing cylinder 1 along the horizontal direction as an example, the front side of the clothes containing cylinder 1 has a clothes taking and placing opening, and a user puts clothes into or takes clothes out of the clothes containing cavity 1a from the front. During the rotation of the clothes containing cylinder 1, the clothes are moved from the lower side to the upper side, and the clothes fall from the upper side to the lower side under the action of gravity, so that the clothes are dispersed, beaten and changed in posture under the joint action of the clothes containing cylinder 1 and gravity.
[0081] In some embodiments, referring to FIG. 2, the clothes containing cylinder 1 is substantially in the form of a hollow cylinder.
[0082] In an embodiment, the clothes containing cylinder 1 can be a single-cylinder structure. That is, the clothes treating device has only the clothes containing cylinder 1 as a cylinder.
[0083] In an embodiment, an outer barrel can be sleeved outside the clothes containing cylinder 1. That is, the clothes treating device has two cylinders.
[0084] The clothes containing cylinder 1 can be made of a metal material, such as a stainless steel material.
[0085] In the related art, an electric conductivity sensor is usually composed of two metal strips, and a wet load contacts the two metal strips to realize circuit conduction, so as to determine the drying degree of clothes. The two metal strips can be regarded as only a single resistor, and the electric conductivity detection sensitivity of the two metal strips is low, and in some scenarios, the dryness determination is prone to problems, for example, for a load of coral velvet, the coral velvet is prone to not being dried; for example, for a mixed load composed of cotton, hemp and chemical fiber, since the electric conductivity values of the cotton, hemp and chemical fiber when being dried are different, the cotton is prone to being over-dried.
[0086] In an embodiment, referring to FIGS. 8 to 11, the electric conductivity detection device 3 includes a first electrode piece 31 and a second electrode piece 32, and the first electrode piece 31 and the second electrode piece 32 are both located on the outer surface of the lifting rib 2. The first electrode piece 31 includes a first connecting portion 311 and a first tooth 312 connected with the first connecting portion 311. The second electrode piece 32 includes a second connecting portion 321 and a second tooth 322 connected with the second connecting portion 321, and the first tooth 312 and the second tooth 322 are arranged in a spaced manner. The first tooth 312 can extend toward the second connecting portion 321, and the second tooth 322 can extend toward the second connecting portion 321. The distance between the first tooth 312 and the second tooth 322 is greater than zero.
[0087] In this embodiment, one first tooth 312 and one second tooth 322 constitute an electrode pair, and the distance between the first tooth 312 and the second tooth 322 can be small, so as to improve the accuracy and sensitivity of the electric conductivity detection device 3.
[0088] In an embodiment, referring to FIGS. 8-11, the first teeth 312 and the second teeth 322 are both at least two in number, and the first teeth 312 and the second teeth 322 are alternately arranged along the axial direction of the clothes drum 1. That is, there is a second tooth 322 between any two adjacent first teeth 312.
[0089] The first teeth 312 and the second teeth 322 are uniformly or non-uniformly arranged along the axial direction of the clothes drum 1. The distance between adjacent first teeth 312 and second teeth 322 is L, and the first teeth 312 and the second teeth 322 are uniformly arranged along the axial direction of the clothes drum 1, which means that any two distances L are equal. The first teeth 312 and the second teeth 322 are non-uniformly arranged along the axial direction of the clothes drum 1, which means that at least two distances L are not equal.
[0090] In this embodiment, the first teeth 312 and the second teeth 322 are alternately and spacedly arranged to form an interdigital structure, one first tooth 312 and one second tooth 322 form an electrode pair, the conductivity detection device 3 has at least two electrode pairs, the clothes contacts at least two electrode pairs, and the conduction between each electrode pair can be regarded as a resistance. At least two electrode pairs can be regarded as at least two resistances in parallel, so that the detection of conductivity change is more sensitive, the accuracy and sensitivity of the conductivity detection device 3 are improved, and problems such as under-drying or over-drying can be avoided to some extent, and the drying performance is improved.
[0091] In some embodiments, the first teeth 312 and the second teeth 322 are uniformly or non-uniformly arranged in the front-rear direction. That is, the axial direction of the clothes drum 1 can be consistent with the front-rear direction.
[0092] It can be understood that the axial direction of the clothes drum 1 refers to the extension direction of the rotation axis of the clothes drum 1.
[0093] The specific structural form of the first teeth 312 is not limited, which can be in the form of a sheet or a column, etc. The specific structural form of the second teeth 322 is not limited, which can be in the form of a sheet or a column, etc. The cross-sectional shape of the column is not limited, which can be circular or polygonal, etc. The polygonal shape can include a rounded polygonal shape.

That is, the first connecting portion 311 and the second connecting portion 321 are both substantially linear or curved structures. For example, the shape of the first teeth 312 is substantially the same as the shape of the second teeth 322, the first teeth 312 are substantially parallel to the second teeth 322, and the first connecting portion 311 and the second connecting portion 321 are both linear structures and are substantially parallel.

[0098] In one embodiment, referring to FIGS. 6, 7, and 11, a portion of the first tooth 312 protrudes away from the lifting rib 2 to form a first protruding portion 3121. The first protruding portion 3121 not only enhances the structural strength of the first tooth 312, but also facilitates contact with the clothes and increases the contact area with the clothes.

[0119] In one embodiment, referring to FIGS. 5 and 6, the reinforcing member 21 includes a reinforcing rib 213 located in the second sub-groove 2ab. The reinforcing rib 213 connects the partition plate 211 and the groove wall surface of the second sub-groove 2ab. The reinforcing rib 213 is used to further increase the structural strength of the lifting rib 2.
[0120] In some embodiments, referring to FIG. 5, the reinforcing member 21 can be multiple, and the multiple reinforcing members 21 are arranged along the front-rear direction at intervals. In this way, the structural strength of the reinforcing rib 2 at multiple positions along the front-rear direction can be effectively increased, and the electrical component and other structural member located in the first sub-groove 2aa can be conveniently put into or taken out of the first sub-groove 2aa.
[0121] In an embodiment, the electrical component 10 includes a control board, and the control board is arranged on the reinforcing rib 2.

The control board and the electrical conductivity detection device 3 are both arranged on the reinforcing rib 2, so as to facilitate the connection between the control board and the electrical conductivity detection device 3.
[0122] The control board can be used to realize input functions such as signal acquisition and processing, and output functions such as sending control instructions to control the operation of the actuator. For example, the control board can control the on-off of power supply.
[0123] In some embodiments, the control board can include an MCU, i.e., a microcontroller unit.
[0124] In an embodiment, referring to FIGS. 5 to 11, the reinforcing rib 2 is formed with a receiving groove 2a, and the laundry treatment apparatus includes a control board located in the receiving groove 2a. The electrical conductivity detection device 3 includes a first terminal 34 and a second terminal 35. The first terminal 34 is connected with the first electrode member 31, and the second terminal 35 is connected with the second electrode member 32. The first terminal 34 and the second terminal 35 both extend into the receiving groove 2a and are connected with the control board.
[0125] For example, the control board can be located in the first sub-groove 2aa. The first terminal 34 is connected with one of the first teeth 312, and the second terminal 35 is connected with one of the second teeth 322.
[0126] In this embodiment, the first terminal 34 and the second terminal 35 are connected with the control board, so as to transmit electrical signals between the control board and the electrical conductivity detection device 3. The first terminal 34, the second terminal 35, and the control board are all located in the receiving groove 2a, so as to avoid the contact between the first terminal 34, the second terminal 35, and the control board and the load as much as possible, and the safety can be improved.
[0127] In an embodiment, referring to FIG. 8, the distance L between the adjacent first tooth 312 and the second tooth 322 is 2mm to 8mm. Exemplarily, the distance L between the adjacent first tooth 312 and the second tooth 322 is 2mm, 3mm, 4mm, 5mm, 6mm, 6.5mm, 7mm or 8mm, etc. The smaller the distance between the first tooth 312 and the second tooth 322, the higher the detection sensitivity, but the more the material of the first electrode member 31 and the second electrode member 32, and the higher the cost. The distance between the adjacent first tooth 312 and the second tooth 322 is 2mm to 8mm, which not only takes into account the detection sensitivity and cost, but also has good anti-static interference effect, to some extent, avoiding the problem of too high conductivity value in the process of drying chemical fiber.
[0128] In an embodiment, referring to FIGS. 1-3, the clothes treatment apparatus includes a wireless power receiving module 4 arranged in the clothes containing drum 1, and the wireless power receiving module 4 can supply power to the conductivity detection device 3.

[0129] In an embodiment, referring to FIGS. 1-3, the wireless power receiving module 4 is located at the rear side of the clothes containing drum 1. Exemplarily, the wireless power receiving module 4 is located at the center area of the rear side wall 11 of the clothes containing drum 1. The wireless power receiving module 4 is located outside the clothes containing cavity 1a to avoid the load such as clothes in the clothes containing cavity 1a from contacting the wireless power receiving module 4, improving safety.

[0132] In this embodiment, the wireless power receiving module 4, the control panel, the cable 5 and the electric conductivity detection device 3 move synchronously with the clothes holding drum 1, and the rotation of the clothes holding drum 1 will not cause the cable 5 to be entangled and the like. The cable 5 transmits the electric energy of the wireless power receiving module 4 to the control panel and the electric conductivity detection device 3, and the reliability is high. At least part of the cable 5 is located in the accommodating groove 2a, which can reduce the probability of the clothes and the like in the clothes holding drum 1 contacting the cable 5, and improve the safety.

On the other hand, the extension 22 covers the wire passing hole 11a, which can avoid exposing the wire passing hole 11a, so that the reinforcing rib 2 can shield the cable 5 entering the clothes holding cavity 1a, and the cable 5 can be prevented from contacting the clothes as much as possible.
[0135] In an embodiment, referring to FIGS. 1 to 3, the clothes treating apparatus includes a cabinet and a wireless power transmitting module 6, the clothes holding drum 1 is located in the cabinet, and the wireless power transmitting module 6 can be arranged on the rear back plate 7 of the cabinet. The wireless power transmitting module 6 and the wireless power receiving module 4 transmit electric energy in a contactless manner, that is, the wireless power transmitting module 6 and the wireless power receiving module 4 can realize electric energy transmission without being connected by wires.
[0136] For example, the wireless power transmitting module 6 includes a transmitting coil, the wireless power receiving module 4 includes a receiving coil, and the transmitting coil and the receiving coil can transmit energy through a magnetic field.

[0139] For example, the wireless power receiving module 4 includes a housing, and the housing is annular, and the receiving coil is contained in the housing. The housing can be used to protect the receiving coil.
[0140] In an embodiment, referring to FIGS. 1-5, the lifting rib 2 includes a main body part 23, and the main body part 23 is arranged on the circumferential surface of the clothes holding cavity 1a, and the electrical conductivity detection device 3 is arranged on the main body part 23. The main body part 23 is arranged on the circumferential surface of the clothes holding cavity 1a, and the main body part 23 extends along the front-rear direction, the length direction of the main body part 23 is consistent with the front-rear direction, and the size of the main body part 23 can be relatively large, so as to facilitate the installation of the electrical conductivity detection device 3.
[0141] It can be understood that, unless otherwise specified, the circumferential direction in the embodiments of the present application is the direction around the rotation axis of the clothes holding drum 1, and the radial direction is the direction along the radius of the clothes holding drum 1. The circumferential side wall 12 of the clothes holding drum 1 is the side wall around the rotation axis of the clothes holding drum 1. The circumferential surface of the clothes holding cavity 1a is the surface around the circumferential direction of the clothes holding cavity 1a.
[0142] In an embodiment, referring to FIGS. 1-5 and FIG. 11, at least part of the electrical conductivity detection device 3 is located on one side of the main body part 23 along the circumferential direction. For example, the entire electrical conductivity detection device 3 is located on one side of the main body part 23 along the circumferential direction. For another example, part of the electrical conductivity detection device 3 is located on one side of the main body part 23 along the circumferential direction, and another part of the electrical conductivity detection device 3 is located on the top side of the main body part 23 away from the circumferential side wall along the radial direction of the clothes holding drum 1. In the process of rotating the clothes holding drum 1, the clothes are prone to rubbing against the top side of the main body part 23 in the case of relative movement between the clothes and the lifting rib 2. In addition, due to the limitation of the diameter of the clothes holding cavity 1a, the size of the main body part 23 is limited, and the area of the top side of the main body part 23 is relatively small, and the area of the side of the main body part 23 along the circumferential direction is relatively large, which facilitates the layout of the electrical conductivity detection device 3. At least part of the electrical conductivity detection device 3 is located on the side of the main body part 23 along the circumferential direction, the size of the electrical conductivity detection device 3 can be relatively large, the number and density of the first electrode 31 and the second electrode 32 can be increased, so as to facilitate the improvement of detection accuracy, and the abrasion between the clothes and the first electrode 31 and the second electrode 32 can be reduced.
[0143] In an embodiment, referring to FIGS. 1-7, the main body 23 includes two side plates 231, a top plate 232, and an end plate 233. The two side plates 231 are circumferentially spaced apart, and the bottom ends of the two side plates 231 are connected to the circumferential side wall 12 of the clothes holding drum 1. The top plate 232 is connected to the top ends of the two side plates 231. The end plate 233 is connected to the front ends of the two side plates 231. The internal space defined by the top plate 232, the end plate 233, and the two side plates 231 is part of the accommodation groove 2a. At least part of the conductivity detection device 3 is located on the outer surface of the side plate 231. The first electrode member 31 and the second electrode member 32 are substantially in the same plane so as to be attached to the side plate 231.
[0144] In an embodiment, referring to FIGS. 5-7, the distance between the top ends of the two side plates 231 is less than the distance between the bottom ends of the two side plates 231. That is, the projection profile of the main body 23 is substantially trapezoidal when viewed in a plane perpendicular to the front-rear direction.
[0145] In an embodiment, referring to FIGS. 1-7, the lifting rib 2 includes an extension 22 connected to the rear end of the main body 23. The extension 22 is arranged on the rear surface of the clothes holding cavity 1a. The arrangement of the extension 22 on the rear surface of the clothes holding cavity 1a can increase the volume of the accommodation groove 2a without increasing the radial dimension of the lifting rib 2 as a whole. Thus, the extension 22 can accommodate structures such as cables 5 and control boards. The extension 22 can cover part of the rear surface of the clothes holding cavity 1a so as to shield structures such as the through-hole 11a of the rear side wall 11 of the clothes holding drum 1.
[0146] In an embodiment, referring to FIGS. 1-7, the extension 22 is open toward the rear side. The rear surface of the clothes holding cavity 1a can shield the opening of the extension 22 toward the rear side. The internal space of the extension 22 can be part of the accommodation groove 2a.
[0147] In an embodiment, referring to FIGS. 1-4, the extension 22 can extend toward the rotation axis of the clothes holding drum 1. In the radial direction of the clothes holding drum 1, the vertex of the extension 22 protrudes beyond the vertex of the main body 23. That is, the outer profile of both the main body 23 and the extension 22 is substantially L-shaped.
[0148] In an embodiment, referring to FIGS. 1-4, the rear surface of the extension 22 is attached to the rear surface of the clothes holding cavity 1a. In this way, the gap between the extension 22 and the rear surface of the clothes holding cavity 1a can be reduced, and the lint in the clothes holding cavity 1a can be prevented from entering the accommodation groove 2a through the gap.
[0149] In an embodiment, the lifting rib 2 can be in sealing contact with the surface of the clothes containing cavity 1a. For example, the extension part 22 is in sealing contact with the surface of the clothes containing cavity 1a, and the main body part 23 is in sealing contact with the surface of the clothes containing cavity 1a. Specifically, both of the two side plates 231 and the end plate 233 are in sealing contact with the circumferential surface of the clothes containing cavity 1a. In this way, the containing groove 2a is substantially a sealed chamber. In the case that the clothes treatment apparatus is a washer-dryer, the probability of water or the like entering the containing groove 2a is reduced, so as to avoid the electrical elements such as the first terminal 34, the second terminal 35, the cable 5 and the control board in the containing groove 2a from being affected.
[0150] In some embodiments, the cable 5 can be sealed through the wire passing hole 11a. That is, the gap between the cable 5 and the hole wall surface of the wire passing hole 11a can be sealed. For example, the gap between the cable 5 and the hole wall surface of the wire passing hole 11a can be sealed by a sealing ring or other sealing structure. In this way, in the case that the clothes treatment apparatus is a washer-dryer, the gap between the cable 5 and the hole wall surface of the wire passing hole 11a can be prevented from leaking water or air.
[0151] In an embodiment, referring to FIGS. 2 and 3, the clothes containing drum 1 includes a drum body 101 and a rear end cover 102, the front side of the drum body 101 has a clothes feeding opening, and the rear end cover 102 closes the rear end opening of the drum body 101. The wire passing hole 11a can be formed in the rear end cover 102, and the wireless power receiving module 4 can be arranged at the rear side of the rear end cover 102.
[0152] In an embodiment, the clothes treatment apparatus includes a circulating air duct, the rear side wall 11 of the clothes containing drum 1 is formed with at least one air inlet communicating with the clothes containing cavity 1a, and the circulating air duct communicates the air inlet and the air outlet of the clothes containing cavity 1a. For example, the rear end cover 102 is formed with the air inlet. The circulating air duct is used to provide circulating air flow repeatedly flowing through the clothes containing cavity 1a. The air flow of the circulating air duct can enter the clothes containing cavity 1a through the air inlet, and the air flow in the clothes containing cavity 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 cavity 1a.
[0153] 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.
[0154] In an embodiment, the laundry treating apparatus includes a cabinet, a hood, and a base. The base is located in the cabinet and below the laundry containing drum 1. The rear side wall of the cabinet forms an air return opening and an air supply opening in communication with the air inlet opening. The height of the air return opening is lower than the height of the air supply opening. The base forms a heat exchange channel. The heat exchange channel is in communication with the air outlet opening and the air return opening. The hood is arranged around the air supply opening and the air return opening and cooperates with the rear side wall of the cabinet to define an air supply channel. The heat exchange channel and the air supply channel jointly form a circulating air duct. The heat exchange channel is located upstream of the air supply channel along the direction of air flow in the circulating air duct. 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.
[0155] The number of air supply openings is not limited. There can be one or more air supply openings, for example, two, three, four, or five air supply openings, and so on.
[0156] In an embodiment, the laundry treating apparatus includes a heat exchange assembly located in the heat exchange channel. The heat exchange assembly is configured to exchange heat with the air flow in the heat exchange channel, thereby dehumidifying and heating. The humid and hot air flow in the laundry containing cavity 1a can enter the heat exchange channel through the air outlet opening, exchange heat with the heat exchange assembly, and be converted into dry and hot air flow. The dry and hot air flow enters the air supply channel through the air return opening, and then returns to the laundry containing cavity 1a through the air supply opening and the air inlet opening.
[0157] In some embodiments, the heat exchange assembly includes a condenser and an evaporator. The laundry treating apparatus 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. 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 configured to cool and dehumidify the humid and hot air flow from the laundry containing cavity 1a into dry and cold air flow. The condenser is configured to heat the dry and cold air flow into dry and hot air flow to return to the laundry containing cavity 1a.
[0158] 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 exhaust. The high-pressure refrigerant enters 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 becomes a low-pressure, low-temperature gas-liquid two-phase mixture that enters the evaporator. The refrigerant in the evaporator absorbs heat from the air flow to become low-pressure gas. The low-pressure gas is sucked into the compressor again. This cycle is repeated to exchange heat. That is, the evaporator is configured to cool and dehumidify the humid and hot air flow from the laundry containing cavity 1a into dry and cold air flow. The condenser is configured to heat the dry and cold air flow into dry and hot air flow to return to the laundry containing cavity 1a. The dry and hot air flow returning to the laundry containing cavity 1a contacts the humid clothes to form humid and hot air flow again, completing one drying cycle. By repeatedly running the drying cycle, the circulating air flow is continuously provided to the laundry containing cavity 1a to dry the clothes.
[0159] Exemplarily, the evaporator and the condenser can each be a finned tube heat exchanger.
[0160] Exemplarily, the throttling device includes, but is not limited to, an electronic expansion valve, etc.
[0161] In an embodiment, the clothes treatment apparatus includes a fan wheel for driving the airflow. Exemplarily, the fan wheel is located in the heat exchange passage and between the heat exchange assembly and the return air inlet. During the drying of 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.
[0162] In some embodiments, the cabinet can be substantially hexahedral, for example, a cube or a cuboid.
[0163] In some cases, the inner space of the reinforcing rib has many reinforcing ribs, and the internal structure is complex. For example, the reinforcing ribs isolate the inner space of the reinforcing rib into multiple chambers distributed along the length direction of the reinforcing rib, and the volume of each chamber is too small to place electrical components or other structural members.
[0164] Referring to FIGS. 1, 2 and 12, the reinforcing rib 2 is formed with a receiving groove 2a extending along the length direction. Specifically, the receiving groove 2a extends along the length direction of the reinforcing rib 2, that is, the length direction of the receiving groove 2a is consistent with the length direction of the reinforcing rib 2. The receiving groove 2a does not interrupt along the length direction of the reinforcing rib 2, and the receiving groove 2a can be a channel extending along the length direction.
[0165] In this embodiment, the reinforcing rib 2 is formed with a receiving groove 2a extending along the length direction. In this way, the size of the receiving groove 2a along the length direction can be large enough to place the electrical component 10 or other structural members. The receiving groove 2a can provide a mounting position for the electrical component 10 or other structural members, and the electrical component 10 or other structural members located in the receiving groove 2a can move with the clothes holding drum 1. The reinforcing rib 2 can be used to move the clothes in the clothes holding cavity 1a and also can be reused to provide a mounting space for the electrical component 10. To some extent, the electrical component 10 located in the receiving groove 2a is protected from contacting the clothes, and the assembly convenience of the electrical component 10 is improved.
[0166] In an embodiment, referring to FIGS. 1, 2 and 12, at least part of the electrical component 10 is arranged in the receiving groove 2a.
[0167] At least part of the electrical component 10 arranged in the receiving groove 2a can mean that the entire electrical component 10 is located in the receiving groove 2a, or part of the electrical component 10 is located in the receiving groove 2a.
[0168] The number of the electrical component 10 can be one, two, three or more.

[0174] The control board can control power supply on / off, for example, the control board can turn on or off power transmission of the wireless power receiving module 4. The control board can also be used to realize other control functions.
[0175] In this embodiment, the wireless power receiving module 4, the control board and the cable 5 move synchronously with the drum 1, so that rotation of the drum 1 will not cause the cable 5 to be entangled and the like. The cable 5 transmits power from the wireless power receiving module 4 to the control board, which has high reliability. At least part of the cable 5 is arranged in the accommodating groove 2a, which can reduce the probability of the load such as clothes in the drum 1 contacting the cable 5, and improve safety.

[0178] In this embodiment, at least one of the control board and the wireless receiving circuit board is arranged in the accommodating groove 2a, so as to protect the control board and / or the wireless receiving circuit board from contacting clothes and reduce damage risk.
[0179] In some embodiments, a wireless receiving circuit board can be arranged on the cable 5 between the control board and the wireless power receiving module 4. That is, the cable 5 can be divided into two sections, one of which connects the wireless power receiving module 4 and the wireless receiving circuit board, and the other of which connects the wireless receiving circuit board and the control board. The wireless receiving circuit board can process the electrical signal from the wireless power receiving module 4 and then transmit it to the control board. For example, the voltage of the control board is low, and the wireless receiving circuit board can reduce the voltage from the wireless power receiving module 4 to 12V or 5V before transmitting it to the control board.
[0180] It should be noted that the unit "V" is volt.

For example, the accommodation groove 2a can extend uninterruptedly from the main body portion 23 to the extension portion 22. The space in the main body portion 23 and the space in the extension portion 22 are both the accommodation groove 2a.
[0183] In an embodiment, referring to FIGS. 1-5 and 12, the first sub-groove 2aa can be a through groove in the length direction. The at least one electrical component 10 is located in the first sub-groove 2aa.
[0184] In this embodiment, the partition plate 211 divides the accommodation groove 2a into the first sub-groove 2aa and the second sub-groove 2ab distributed in the radial direction, instead of multiple sub-grooves distributed in the front-rear direction. The first sub-groove 2aa can extend from the front end of the lifting rib 2 to the rear end of the lifting rib 2, so that the first sub-groove 2aa can accommodate an electrical component 10 or other structural member with a relatively long length.
[0185] In some embodiments, referring to FIG. 5, the partition plate 211 can be multiple, and the multiple partition plates 211 are arranged in the front-rear direction at intervals.

[0197] In the related art, during the operation of the traditional clothes dryer, the temperature control is often not accurate enough, which can easily lead to uneven drying, and the laundry can be over-dried or incompletely dried.

[0207] One of the two detection electrodes 911 of the first detection unit 91 is a positive electrode, and the other is a negative electrode.
[0208] The positive electrodes of the respective first detection units 91 can be electrically connected, and the negative electrodes of the respective first detection units 91 can be electrically connected.
[0209] In this embodiment, one positive electrode and one negative electrode constitute one first detection unit 91. Taking the first detection unit 91 for detecting the electrical conductivity as an example, the clothes contact at least two first detection units 91 to turn on the electrical conductivity detection circuit. The turn-on between each first detection unit 91 can be regarded as one resistance, and the at least two first detection units 91 can be regarded as at least two resistances in parallel, so that the detection of the change in the electrical conductivity is more sensitive, the accuracy and sensitivity of the first detection unit 91 are improved, and the problems of insufficient drying or over-drying and the like can be avoided to some extent, and the drying performance is improved.
[0210] The detection electrode 911 can be made of a conductive material, for example, the detection electrode 911 is made of a metal material, for example, a stainless steel material.
[0211] In some embodiments, the detection electrode 911 can be an integrally formed structure. The detection electrode 911 has good strength.
[0212] In some embodiments, the detection electrode 911 is a sheet metal structure.
[0213] The sheet metal structure refers to a structure formed by cold working such as stamping, shearing or bending of a metal plate.
[0214] In this embodiment, the detection electrode 911 is a structure formed by cold working of a metal plate, which has good structural strength and low manufacturing cost.
[0215] In some embodiments, referring to FIGS. 20-22, the detection electrode 911 includes a first sensing portion 9111 and two second sensing portions 9112, the two second sensing portions 9112 are arranged along a second direction, the first sensing portion 9111 connects the two second sensing portions 9112, and the first direction intersects the second direction.
[0216] The first direction and the second direction can be perpendicular or oblique. In some cases, the first direction can be a front-rear direction, and the second direction can be a circumferential direction of the clothes drum 1.
[0217] In this embodiment, the two second sensing portions 9112 are arranged along the second direction, and the first sensing portion 9111 connects the two second sensing portions 9112. In this way, the area of the detection electrode 911 in contact with the clothes can be increased without significantly increasing the size of the detection electrode 911 along the first direction, and the detection accuracy can be improved.
[0218] In some embodiments, referring to FIGS. 13, 20-22, the two second sensing portions 9112 are respectively located on two outer side surfaces of the lifting rib 2 along the circumferential direction of the clothes drum 1, and the first sensing portion 9111 is located on a top side surface of the lifting rib 2 close to the rotation axis of the clothes drum 1 along the radial direction. The top side surface of the lifting rib 2 is away from the circumferential surface of the clothes drum 1a along the radial direction. Here, the radial direction refers to the radial direction of the clothes drum 1, which is perpendicular to the axial direction of the clothes drum 1. In this way, the area and probability of contact between the detection electrode 911 and the clothes can be improved, and the connection between the detection electrode 911 and the lifting rib 2 can also be strengthened.
[0219] In some embodiments, referring to FIGS. 20-22, the second sensing portion 9112 includes a main plate body 91121 and a profiled portion 91122 formed by stamping.

The profiled portion 91122 protrudes away from the lifting rib 2, that is, the profiled portion 91122 and the main plate body 91121 are not in the same plane. This facilitates the contact between the profiled portion 91122 and the clothes, increases the contact area between the profiled portion 91122 and the clothes, and improves the detection accuracy.
[0221] In some embodiments, the corners of the detection electrode 911 are arc-shaped. For example, the corners of the main plate body 91121 are circularly arc-shaped. By reducing the sharp corners of the detection electrode 911, the stress concentration points can be reduced, and the risk of hooking the clothes can also be reduced.
[0222] In some embodiments, the surface of the profiled portion 91122 is arc-shaped. The surface of the profiled portion 91122 needs to be in contact with the clothes.

[0224] The transition wall 91122b forms a horn-shaped space that opens to the side away from the contact wall 21122a and gradually expands, that is, the cross-sectional area of the space surrounded by the transition wall 91122b gradually expands in the direction away from the contact wall 21122a.
[0225] Exemplarily, the second detection unit 92 can be accommodated in the horn-shaped space.
[0226] In this embodiment, during the process of forming the profiling portion 91122 by stamping with a stamping tool, the transition wall 91122b forms a horn-shaped space that opens to the side away from the contact wall 21122a and gradually expands, which facilitates the stamping tool to separate from the profiling portion 91122 in the direction away from the contact wall 21122a, and reduces the manufacturing difficulty.
