[0048] In other examples, the clothes treatment device can further include an outer drum arranged at the circumferential outer side of the clothes treatment drum 3.

[0049] Embodiments of the present application are described taking the clothes treatment device adopting a single drum structure as an example.

[0050] Exemplarily, the clothes treatment drum 3 is substantially in the shape of a hollow cylinder. The clothes treatment drum 3 can be made of metal material, such as stainless steel material, etc., which is not limited herein.

[0051] In some embodiments, please refer to Figures 1 to 3 , the clothes treatment device includes a cabinet 6, and the clothes treatment drum 3 is rotatably arranged in the cabinet 6.

[0052] The cabinet 6 is used to accommodate structural members such as the clothes treatment drum 3, and the cabinet 6 serves as an appearance component of the clothes treatment device and protects the clothes treatment drum 3.

[0057] The lifting rib 1 is used to drive the laundry to rotate.

[0058] The lifting rib 1 can be arranged on the circumferential surface of the laundry treatment cavity 3a, and the lifting rib 1 protrudes radially from the circumferential surface of the laundry treatment cavity 3a. Specifically, the lifting rib 1 can contact the laundry in the laundry treatment cavity 3a and drive the laundry to rotate with the laundry treatment drum 3. For example, the laundry moves upward under the action of the lifting rib 1, and then moves downward under the action of gravity and centrifugal force, and so on. In this way, the laundry continuously changes its posture in the laundry treatment cavity 3a.

[0059] It can be understood that the circumferential surface of the laundry treatment cavity 3a is the side surface of the laundry treatment cavity 3a around the rotation axis of the laundry treatment drum 3, i.e., the inner circumferential surface of the laundry treatment drum 3.

[0060] Specifically, the first detection unit 21 and the second detection unit 22 are both used to detect a parameter of the load, e.g., the laundry, in the laundry treatment cavity 3a. The first detection unit 21 is a structure capable of realizing an electrical function and / or used in an electrical circuit to realize at least one electrical function. The second detection unit 22 is a structure capable of realizing an electrical function and / or used in an electrical circuit to realize at least one electrical function. Both the first detection unit 21 and the second detection unit 22 can receive electrical power and are used to detect the parameter of the laundry.

[0061] The parameter is used to represent the state of the laundry in the laundry treatment cavity 3a, e.g., the parameter is used to represent the washing and / or drying state of the laundry.

[0062] The type of the parameter is not limited, and in some embodiments, the parameter includes at least one of electrical conductivity, temperature, and pressure.

[0067] The first detection unit 21 and the second detection unit 22 are integrated in the lifting rib 1, that is, the first detection unit 21 and the second detection unit 22 are fixed on the lifting rib 1, and the first detection unit 21 and the second detection unit 22 can move with the lifting rib 1.

[0068] The lifting rib assembly provided by the embodiment of the application is used for driving clothes to rotate, the first detection unit 21 and the second detection unit 22 are integrated in the lifting rib 1, the lifting rib 1 provides a fixed position for the first detection unit 21 and the second detection unit 22, the first detection unit 21 and the second detection unit 22 can move with the lifting rib 1, and the first detection unit 21 and the second detection unit 22 can closely contact the load in the clothes treatment cavity 3a, for example, clothes, so that the detection accuracy is improved.

[0069] In the related art, during the operation of the traditional clothes dryer, the temperature control is often not accurate enough, which can easily cause uneven drying, and the clothes can be over-dried or incompletely dried, and in addition, the clothes can be damaged due to the high temperature, and the clothes can be deformed, discolored, or have a shortened service life.

[0070] In some examples, the first detection unit 21 is used for detecting the electrical conductivity, and the second detection unit 22 is used for detecting the temperature.

[0071] In the embodiment, the first detection unit 21 and the second detection unit 22 are integrated in the lifting rib 1, the second detection unit 22 can closely contact the load in the clothes treatment cavity 3a, which can greatly improve the accuracy of temperature detection, effectively solve the temperature control problem, and the first detection unit 21 can contact the load in the clothes treatment cavity 3a, for example, clothes, so that the drying degree of the clothes is determined by the temperature and humidity of the clothes. For example, the second detection unit 22 is used for detecting the temperature, and the drying degree of the clothes can be determined by the temperature, the first detection unit 21 can detect the electrical conductivity, the electrical conductivity is related to the water content, that is, the humidity of the clothes, and the water content of the clothes can be determined by the electrical conductivity, so that the detection device can detect the temperature of the clothes and the electrical conductivity of the clothes, the judgment accuracy can be improved, and the problem of over-drying or insufficient drying can be solved to some extent.

[0072] In some examples, the first detection unit 21 is used for detecting the electrical conductivity, and the second detection unit 22 is used for detecting the pressure.

[0076] In some examples, the first detection unit 21 is configured to detect pressure, and the second detection unit 22 is configured to detect temperature.

[0077] For the convenience of describing the principle of the related structure, in the following description of some embodiments, the first detection unit 21 is configured to detect conductivity, and the second detection unit 22 is configured to detect temperature. It can be understood that the first detection unit 21 can also be configured to detect pressure or temperature, and the second detection unit 22 can also be configured to detect conductivity or pressure. Therefore, the application will not be described again.

[0078] In some embodiments, referring to Figures 8 to 10 , the first detection unit 21 includes two detection electrodes 211 arranged along a first direction, and a plurality of first detection units 21 are arranged along the first direction.

[0079] One of the two detection electrodes 211 of the first detection unit 21 is a positive electrode, and the other is a negative electrode.

[0080] The positive electrodes of the first detection units 21 can be electrically connected, and the negative electrodes of the first detection units 21 can be electrically connected.

[0081] In this embodiment, one positive electrode and one negative electrode constitute one first detection unit 21. Taking the first detection unit 21 configured to detect conductivity as an example, the clothes contact at least two first detection units 21 to turn on the conductivity detection circuit. The turn-on between each first detection unit 21 can be regarded as a resistance, and the at least two first detection units 21 can be regarded as at least two resistances in parallel, so that the detection of the change in conductivity is more sensitive, the accuracy and sensitivity of the first detection unit 21 are improved, and the problems of insufficient drying or over-drying can be avoided to some extent, and the drying performance is improved.

[0082] The detection electrode 211 can be made of a conductive material, for example, the detection electrode 211 is made of a metal material, for example, a stainless steel material.

[0083] In some embodiments, the detection electrode 211 can be an integral structure. The detection electrode 211 has good strength.

[0084] In some embodiments, the detection electrode 211 is a sheet metal structure.

[0085] The sheet metal structure refers to a structure formed by cold working such as stamping, shearing or bending of a metal plate.

[0086] In this embodiment, the detection electrode 211 is a structure formed by cold working of a metal plate, which has good structural strength and low manufacturing cost.

[0087] In some embodiments, referring to Figures 8 to 10 , the detection electrode 211 comprises a first sensing portion 2111 and two second sensing portions 2112, the two second sensing portions 2112 are arranged along a second direction, and the first sensing portion 2111 connects the two second sensing portions 2112, and the first direction intersects the second direction.

[0088] The first direction and the second direction can be perpendicular or oblique. In some cases, the first direction can be the front-back direction, and the second direction can be the circumferential direction of the clothes treatment drum 3.

[0089] In this embodiment, the two second sensing portions 2112 are arranged along the second direction, and the first sensing portion 2111 connects the two second sensing portions 2112, so that the area of the detection electrode 211 in contact with the clothes can be increased without significantly increasing the size of the detection electrode 211 along the first direction, and the detection accuracy can be improved.

[0090] In some embodiments, referring to Figure 1 , Figures 8 to 10 , the two second sensing portions 2112 are respectively located on the two outer sides of the lifting rib 1 along the circumferential direction of the clothes treatment drum 3, and the first sensing portion 2111 is located on the top side of the lifting rib 1 close to the rotation axis of the clothes treatment drum 3 along the radial direction. The top side of the lifting rib 1 is away from the circumferential surface of the clothes treatment cavity 3a along the radial direction. Here, the radial direction refers to the radial direction of the clothes treatment drum 3, which is perpendicular to the axial direction of the clothes treatment drum 3. In this way, the area and probability of contact between the detection electrode 211 and the clothes can be improved, and the connection between the detection electrode 211 and the lifting rib 1 can also be strengthened.

[0091] In some embodiments, referring to Figures 8 to 10 , the second sensing portion 2112 comprises a main plate body 21121 and a profiled portion 21122 formed by stamping, the profiled portion 21122 protrudes away from the lifting rib 1, and the profiled portion 21122 is connected to the main plate body 21121.

[0092] In this embodiment, the profiled portion 21122 is formed by stamping, that is, the profiled portion 21122 can be formed by stamping process, so that the strength and rigidity of the detection electrode 211 can be improved. The profiled portion 21122 protrudes away from the lifting rib 1, that is, the profiled portion 21122 and the main plate body 21121 are not in the same plane, which facilitates the contact between the profiled portion 21122 and the clothes, increases the contact area between the profiled portion 21122 and the clothes, and improves the detection accuracy.

[0093] In some embodiments, the corners of the detection electrode 211 are arc-shaped. For example, the corners of the main plate body 21121 are circularly arc-shaped. By reducing the sharp corners of the detection electrode 211, the stress concentration points can be reduced, and the risk of hooking the clothes can also be reduced.

[0094] In some embodiments, the surface of the profiling portion 21122 is arc-shaped. The surface of the profiling portion 21122 is in contact with the clothes, and the arc-shaped surface can avoid hooking the clothes to some extent, reduce the mutual abrasion between the clothes and the surface of the profiling portion 21122, and also reduce stress concentration.

[0095] In some embodiments, referring to Figures 8 to 10 , the profiling portion 21122 includes a contact wall 21122a and a transition wall 21122b. The contact wall 21122a is located on the side of the main plate body 21121 away from the reinforcing rib 1. The transition wall 21122b surrounds the contact wall 21122a, and the transition wall 21122b connects the contact wall 21122a and the main plate body 21121. The transition wall 21122b surrounds to form a horn-shaped space that opens to the side away from the contact wall 21122a and gradually expands.

[0096] The transition wall 21122b surrounds to form 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 21122b gradually expands in the direction away from the contact wall 21122a.

[0097] Exemplarily, the second detection unit 22 can be accommodated in the horn-shaped space.

[0098] In this embodiment, during the process of forming the profiling portion 21122 by stamping with a stamping tool, the transition wall 21122b surrounds to form 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 21122 in the direction away from the contact wall 21122a, and reduces the manufacturing difficulty.

[0099] The detection electrode 211 can also have other forms, referring to Figures 5 to 7 , the detection electrode 211 includes a connecting portion 2113 and a tooth group 2114. The tooth group 2114 includes a plurality of finger-shaped teeth 21141. The plurality of finger-shaped teeth 21141 are arranged in sequence and spaced apart along the first direction. All finger-shaped teeth 21141 of the tooth group 2114 are connected with the connecting portion 2113. The finger-shaped teeth 21141 of the two detection electrodes 211 are alternately and spaced apart along the first direction.

[0102] The connection position of the finger-shaped teeth 21141 and the connecting portion 2113 is not limited, and exemplarily, the connecting portion 2113 can be connected to any position of the length direction of the finger-shaped teeth 21141. In some embodiments, please refer to Figures 6 to 7 , the connecting portion 2113 is connected to one end of the length direction of the finger-shaped teeth 21141. As an example, all the finger-shaped teeth 21141 of the tooth group 2114 are located on the same side of the connecting portion 2113. In this way, the connecting portion 2113 and the single tooth group 2114 are substantially comb-shaped.

[0103] In some embodiments, please refer to Figures 5 to 7 , the finger-shaped teeth 21141 include a main plate body 21121 and a profiled portion 21122 formed by stamping, the profiled portion 21122 protrudes away from one side of the lifting rib 1, and the profiled portion 21122 is connected to the main plate body 21121.

[0105] The electrical connection terminal 2115 can be connected with one of the finger-shaped teeth 21141, the connecting portion 2113, the first sensing portion 2111 and the second sensing portion 2112.

[0106] In some embodiments, please refer to Figures 4 to 8The first detection unit 21 comprises a detection electrode 211, at least part of the detection electrode 211 is located on the outer surface of the lifting rib 1, and the second detection unit 22 is arranged on the detection electrode 211.

[0107] At least part of the detection electrode 211 is located on the outer surface of the lifting rib 1, which can be that part of the detection electrode 211 is located on the outer surface of the lifting rib 1, or the whole structure of the detection electrode 211 is located on the outer surface of the lifting rib 1.

[0108] The second detection unit 22 and the detection electrode 211 can be detachably connected or non-detachably connected.

[0109] In this embodiment, at least part of the detection electrode 211 is located on the outer surface of the lifting rib 1, the detection electrode 211 can be in contact with the load such as clothes in the clothes treatment cavity 3a, thereby sensing the drying degree of the clothes at close range, and effectively improving the accuracy of judging the drying degree of the clothes. The detection electrode 211 can provide a mounting position for the second detection unit 22.

[0110] In some embodiments, the second detection unit 22 is located on the side of the detection electrode 211 close to the lifting rib 1.

[0114] The NTC temperature sensor, also known as Negative Temperature Coefficient Sensor, has a negative temperature coefficient thermistor.

[0115] The detection principle of the NTC temperature sensor is that under a certain measurement power, the resistance value of the negative temperature coefficient thermistor rapidly decreases with the temperature rising, and by using the characteristics of the negative temperature coefficient thermistor, the corresponding temperature is determined by measuring the resistance value of the negative temperature coefficient thermistor, thereby achieving the purpose of detecting the temperature.
