Description
Technical Field
[0001] The present invention relates to the technical field of clothing processing equipment, and in particular provides a clothing processing equipment. Background Art
[0002] With the continuous updating of automation products, equipment for drying and washing clothes has become a must-have household appliance in the home. Existing clothing processing equipment often uses a solution that determines whether the clothes are dry by contacting the outer surface of the clothes with a detection electrode. However, in actual applications, this contact detection solution often makes incorrect judgments. For example, when using a clothing processing device to dry clothes, as the drum rotates, the clothes in the drum may become tangled or clumped. When the detection electrode contacts the knotted or clumped clothes, it detects that the surface is dry and stops the drying operation. At this time, the clothes are likely to be dry on the outside but still wet on the inside, resulting in a high judgment error rate. At the same time, the detection distance of existing clothing processing equipment is short, and it can only detect clothes near the door. When the amount of clothes is large, it is impossible to detect all the clothes in the drum. Due to its short detection distance, it is easy to cause a high judgment error rate.
[0003] Therefore, this field needs a new technical solution to solve the above problems. Summary of the Invention

[0039] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. For example, although the clothing processing device of the present invention is described in the specification using a clothes dryer as an example, the technical solution of the present invention is not limited thereto. Those skilled in the art can apply the technical solution of the present invention to clothing processing devices in other locations, such as a washer-dryer, etc., as needed. Such changes to the application object do not deviate from the principles and scope of the present invention.
[0040] It should be noted that in the description of the present invention, terms such as "upper," "lower," "left," "right," "front," "back," "inner," and "outer" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. These are merely for ease of description and are not intended to indicate or imply that the device or component described must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0041] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "connect," "dispose," and "install" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections, direct connections, or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.
[0042] See first Figures 1 to 4 , the clothes processing device of the present invention is described.
[0043] like Figures 1 to 3 As shown, the clothing processing device of the present invention includes a drum 1, a detection electrode 2 and a power supply component 3; wherein, a plurality of lifting ribs 11 are provided on the inner side wall of the drum 1; each group of detection electrodes 2 includes a first electrode 21 and a second electrode 22 arranged opposite to each other, and the first electrode 21 and the second electrode 22 are respectively arranged in two adjacent lifting ribs 11, and are configured to form a capacitor to detect clothing parameters of the clothing between the two; the power supply component 3 is configured to be able to power on or off the first electrode 21 and the second electrode 22.
[0044] Specifically, when the power is on, when the clothing to be tested exists between the first electrode 21 and the second electrode 22 in a set of detection electrodes 2, the clothing to be tested can be used as a target dielectric to be tested of the capacitor. When the clothing is judged to be dry, the capacitance value between the two electrodes can be obtained, and the obtained capacitance value can be used as the clothing parameter of the clothing.
[0045] Furthermore, the capacitance value refers to the ability to store charge between the two electrodes, which is only related to the dryness of the clothes to be tested (when the clothes are completely dry, the capacitance value is the largest), and has nothing to do with whether the clothes to be tested are knotted or clumped. Regardless of whether the clothes are clumped or knotted, it will not affect the capacitance value. Therefore, it can avoid the problem of misjudgment caused by knotting or clumping of clothes and reduce the error rate of judgment.
[0046] Preferably, the first electrode piece 21 and the second electrode piece 22 in each group of detection electrodes 2 are arranged parallel to each other, so that the first electrode piece 21 and the second electrode piece 22 can form a parallel plate capacitor, which is conducive to measuring the capacitance value between the two electrode pieces.
[0047] In a preferred embodiment, Figure 4 As shown, the number of lifting ribs 11 is 3, and the number of groups of detection electrodes 2 is 3; however, this is only exemplary and not restrictive, and those skilled in the art can flexibly adjust it according to actual product requirements.
[0048] In one possible implementation, Figure 5 As shown, when the number of the lifting ribs 11 is 2, the two lifting ribs 11 are arranged opposite to each other. At this time, only one group of detection electrodes 2 is set, and the first electrode 21 and the second electrode 22 in the group of detection electrodes 2 are respectively arranged in the two lifting ribs 11.
[0049] It should be noted that the lifting ribs 11 in this application are made of insulating material. The detection electrode 2 is disposed within the lifting ribs 11 to achieve the effect of insulating the detection electrode 2 from the drum 1, thereby preventing the drum 1 from being charged. Those skilled in the art can flexibly adjust the material of the lifting ribs 11 according to actual product conditions, such as polyvinyl chloride plastic (PVC).
[0050] like Figure 4 As shown, the first electrode 21 in any group of detection electrodes 2 and the second electrode 22 in the adjacent group of detection electrodes 2 are arranged in the same lifting rib 11. Through the above arrangement, the data detected by each group of detection electrodes 2 are the clothing parameters of the clothing between the two adjacent lifting ribs 11 where the detection electrodes 2 are located.
[0051] Preferably, multiple lifting ribs 11 are circumferentially spaced apart on the inner wall of the drum 1. This allows the laundry in the drum 1 to rotate, achieving a better drying effect. On the other hand, if there is no distance between two lifting ribs 11, laundry can easily accumulate on them, resulting in inaccurate laundry parameters. Therefore, the spaced-apart lifting ribs 11 also facilitate detection of laundry parameters for laundry between two adjacent lifting ribs 11.
[0052] Furthermore, a plurality of lifting ribs 11 are evenly spaced circumferentially on the inner wall of the drum 1. From the capacitance determination formula C=εS / 4πkd (where ε is the dielectric constant; s is the area facing each other between the two electrodes, d is the distance between the two electrodes, and k is the electrostatic force constant), it can be seen that the capacitance value is related to the distance between the first electrode 21 and the second electrode 22. By evenly arranging the plurality of lifting ribs 11, the plurality of groups of detection electrodes 2 are evenly arranged on the inner wall of the drum 1. The distance between the first electrode 21 and the second electrode 22 in each group of detection electrodes 2 is equal, which can eliminate the problem of adding judgment steps due to the different distances between the first electrode 21 and the second electrode 22 in each group of detection electrodes 2, simplify the steps, and facilitate the detection of clothing parameters.
[0053] Preferably, the first electrode 21 and the second electrode 22 in the same lifting rib 11 do not contact each other, which can prevent the first electrode 21 and the second electrode 22 in the same lifting rib 11 from conducting electricity to each other, thereby affecting the accuracy of the judgment result and reducing the judgment error rate.
[0054] It is worth mentioning that there is no target dielectric between the first electrode 21 and the second electrode 22 in the same lifting rib 11, which will not affect the judgment result of whether the clothes in the drum have been dried.
[0055] It should be noted that the present application does not impose any restrictions on the cross-sectional shape of each set of detection electrode pieces 2. Those skilled in the art can flexibly adjust the shape based on actual product conditions, as long as the cross-sectional shape of the first electrode piece 21 and the second electrode piece 22 in each set of detection electrode pieces 2 is the same. For example, the cross-sectional shape of the detection electrode piece 2 is a straight line; for another example, the cross-sectional shape of the detection electrode piece 2 is a curved line.
[0056] Furthermore, it should be noted that the detection electrode 2 in this application is made of a conductive material. As long as the first electrode 21 and the second electrode 22 can form a capacitor, the material of the detection electrode 2 in this application is not fixed and can be flexibly adjusted by those skilled in the art based on actual product conditions. For example, the detection electrode 2 can be made of a metal material, including but not limited to copper, aluminum, etc.
[0057] Preferably, the lifting ribs 11 are arranged along the length direction of the drum 1. When the drum 1 rotates, the lifting ribs 11 can lift the clothes in the drum 1, thereby assisting in turning and beating the clothes to achieve a better drying effect.
[0058] Preferably, the detection electrode 2 is arranged along the length direction of the lifting rib 11, which increases the detection range of the detection electrode 2, realizes all-round and no-dead-angle detection of the clothes in the drum 1 to a large extent, and greatly reduces the judgment error rate.
[0059] like Figures 1 to 3As shown, the clothes processing device further includes a box body 4 , the drum 1 is arranged in the box body 4 , and the power supply component 3 is arranged in the area enclosed by the box body 4 and the drum 1 .
[0060] The following are combined with the following figures Figures 1 to 9 , different embodiments of the power supply assembly of the present invention are described.
[0061] Example 1
[0062] like Figures 1 to 3 As shown, the power supply assembly 3 includes a power receiving ring 31 provided on the outer wall of the drum 1, and the power receiving ring 31 is electrically connected to the detection electrode 2. Specifically, the power receiving ring 31 and the detection electrode 2 are connected by a wire.
[0063] It should be noted that the power receiving ring 31 in the present application is made of a conductive material. Those skilled in the art can flexibly adjust the material of the conductive material, such as metal, graphite, etc., according to actual product conditions.
[0064] In a preferred embodiment, there are multiple powered rings 31, and they are connected to each group of detection electrodes 2 in a one-to-one correspondence, that is, each powered ring 31 is connected to the first electrode 21 and the second electrode 22 in each group of detection electrodes 2. In this case, when detecting clothing parameters of clothing between any group of detection electrodes 2, the powered ring 31 corresponding to the group of detection electrodes 2 is connected to the group of detection electrodes 2 to energize or deenergize the first electrode 21 and the second electrode 22, thereby detecting clothing parameters of clothing between the group of detection electrodes 2.
[0065] Alternatively, in one possible embodiment, there are multiple power receiving rings 31, and they are respectively connected to the first electrode piece 21 and the second electrode piece 22 in the same lifting rib 11. In this case, when detecting clothing parameters of clothing between any set of detection electrodes 2, the two power receiving rings 31 are respectively connected to the first electrode piece 21 and the second electrode piece 22 in the two adjacent lifting ribs 11 where the detection electrodes 2 are located, so as to energize or deenergize the first electrode piece 21 and the second electrode piece 22 in the set of detection electrodes 2, thereby detecting clothing parameters of clothing between the set of detection electrodes 2.
[0066] Alternatively, in another possible embodiment, there are multiple power receiving rings 31, and each of them is connected to each first electrode 21 and second electrode 22. In this case, when detecting clothing parameters of clothing between any set of detection electrodes 2, the two power receiving rings 31 are respectively connected to the first electrode 21 and the second electrode 22 in the set of detection electrodes 2 to energize or deenergize the first electrode 21 and the second electrode 22 in the set of detection electrodes 2, thereby detecting clothing parameters of clothing between the set of detection electrodes 2.
[0067] Preferably, an insulating layer 5 is provided between the drum 1 and the power receiving ring 31 to prevent the drum 1 from being charged; and to a certain extent, it can also reduce the heat loss inside the drum 1.
[0068] like Figure 2 and Figure 3 As shown, the power supply assembly 3 further includes a power connection plate 32 , which is disposed between the drum 1 and the housing 4 and is configured to be connectable to or disconnectable from the power receiving ring 31 .
[0069] Preferably, the power board 32 is arranged on the left side of the drum 1 (such as Figure 2 Alternatively, the power board 32 can also be set on the right side of the drum 1 (such as Figure 2 on the right side of the ).
[0070] like Figure 6 As shown, the power board 32 includes a base plate 321 and a conductive plate 322. The conductive plate 322 is arranged on a side of the base plate 321 close to the drum 1 (as shown in FIG. Figure 6 on the right side of the ).
[0071] It should be noted that the substrate 321 in this application is made of insulating material. Those skilled in the art can flexibly adjust the material of the substrate 321 according to actual product conditions, such as rubber, resin, etc.
[0072] Preferably, the substrate 321 is away from the side of the conductive plate 322 (eg Figure 6 The left side of the figure is provided with a first magnetic component 33, and the box body 4 is provided with a second magnetic component 41. The first magnetic component 33 and the second magnetic component 41 are configured to attract or repel each other under the action of current to connect or disconnect the conductive plate 322 with the power receiving ring 31.
[0073] Specifically, if Figure 2 As shown, the first magnetic attraction component 33 and the second magnetic attraction component 41 repel each other, so that the conductive plate 322 is connected to the power receiving ring 31 to energize the first pole piece 21 and the second pole piece 22, thereby detecting the clothing parameters of the clothing between the two pole pieces; Figure 3 As shown, the first magnetic attraction component 33 and the second magnetic attraction component 41 attract each other, so that the conductive plate 322 is disconnected from the power receiving ring 31, and the power supply to the first pole piece 21 and the second pole piece 22 stops.
[0074] Preferably, if Figure 2 and Figure 3 As shown, the first magnetic component 33 is a permanent magnet and the second magnetic component 41 is an electromagnet. When the power is on, the direction of the current in the second magnetic component 41 is changed, thereby changing the magnetic pole, so that the first magnetic component 33 and the second magnetic component 41 attract or repel each other, so as to connect or disconnect the conductive plate 322 with the power receiving ring 31.
[0075] Alternatively, the first magnetic component 33 is an electromagnet and the second magnetic component 41 is a permanent magnet; when powered on, the direction of the current in the first magnetic component 33 is changed, thereby changing the magnetic pole, so that the first magnetic component 33 and the second magnetic component 41 attract or repel each other, so as to connect or disconnect the conductive plate 322 with the power receiving ring 31.
[0076] Alternatively, the first magnetic component 33 and the second magnetic component 41 are both electromagnets; when powered on, by changing the current direction of the first magnetic component 33 and the second magnetic component 41, the state of attraction or repulsion between the first magnetic component 33 and the second magnetic component 41 can be changed to connect or disconnect the conductive plate 322 with the power receiving ring 31.
[0077] Preferably, there are multiple conductive plates 322 , and they correspond one-to-one to the power receiving rings 31 . The conductive plates 322 correspond one-to-one to the power receiving rings 31 , and can accurately supply power to the first pole piece 21 and the second pole piece 22 .
[0078] like Figures 1 to 3 As shown, the laundry processing apparatus further includes a hanging assembly 6 , which is disposed above the power board 32 and connected to the power board 32 so as to hang the power board 32 between the drum 1 and the housing 4 .
[0079] Specifically, the hanging assembly 6 includes a hanging rod 61 and a hanging rope 62. The hanging rod 61 is set on the box body 4, and the hanging rope 62 passes through the hanging shaft and is connected to the power connection plate 32, so as to suspend the power connection plate 32 between the drum 1 and the box body 4. The setting of the hanging rod 61 can make the two sides of the power connection plate 32 move synchronously, ensuring that the conductive plates 322 on both sides of the power connection plate 32 are connected or disconnected with the power receiving ring 31 at the same time.
[0080] Alternatively, the hanging assembly 6 only includes a hanging rope 62, at least two hanging ropes 62, and one end of the hanging rope 62 is set on the top of the box body 4 (such as Figure 2 The other end is connected to the power board 32, and the power board 32 can also be suspended between the drum 1 and the box body 4.
[0081] Alternatively, the hanging assembly 6 only includes a hanging rod 61, one end of which is arranged on the box body 4 and hinged to the box body, and the other end is connected to the power board 32, so that the power board 32 can be suspended between the drum 1 and the box body 4. The hanging rod 61 can be arranged on the top of the box body 4 or on the side wall of the box body 4.
[0082] Preferably, a hanging ear 3211 is provided on the base plate 321 , and the hanging rope 62 is connected to the hanging ear 3211 .
[0083] Preferably, if Figure 2 and Figure 3As shown, the clothing processing device also includes a power board 7, which is arranged on the box body 4. The power board 7 is used to send signals to the first magnetic component 33, the second magnetic component 41 and the power board 32, so that the power board 32 can be connected or disconnected with the power receiving ring 31.
[0084] Finally, refer to Figure 2 and Figure 3 , the principle of judging whether the clothes are dried according to the present invention is explained.
[0085] Specifically, if Figure 2 As shown, when the drum 1 stops rotating, the power supply board 7 sends a signal to the first magnetic component 33, the second magnetic component 41, and the power board 32, causing the first magnetic component 33 and the second magnetic component 41 to repel each other and the conductive plate 322 on the power board 32 to be energized. At this time, the conductive plate 322 can communicate with the power receiving ring 31 to energize the first pole piece 21 and the second pole piece 22. When the clothing to be tested exists between the first pole piece 21 and the second pole piece 22, the clothing to be tested can be used as a target dielectric to be tested. When performing the dryness judgment operation, the capacitance value between the two pole pieces is detected, which is the clothing parameter of the clothing to be tested. In this process, the power supply board 7 controls the power supply of different conductive plates 322, thereby obtaining the capacitance value between different groups of detection pole pieces 2, that is, the clothing parameter of the clothing in different groups of detection pole pieces 2.
[0086] Furthermore, if Figure 3 As shown, after the detection is completed, the main controller 7 sends a signal to the first magnetic component 33, the second magnetic component 41 and the power board 32, so that the first magnetic component 33 and the second magnetic component 41 attract each other and the conductive plate 322 on the power board 32 is de-energized. At this time, the conductive plate 322 can be disconnected from the power receiving ring 31, so that the first pole piece 21 and the second pole piece 22 are de-energized.
[0087] Example 2
[0088] like Figure 7 and Figure 8 As shown, the drum 1 includes a clothes-feeding opening 14 and a drum rim 12 disposed on one side of the drum 1. The drum rim 12 is disposed around the clothes-feeding opening 14. The power supply assembly 3 includes a receiving arc 34 disposed on the drum rim 13. The receiving arc 34 is electrically connected to the detection electrode 2. Specifically, the receiving arc 34 and the detection electrode 2 are connected by a wire.
[0089] It should be noted that the arc receiving member 34 in the present application is made of a conductive material, wherein those skilled in the art can flexibly adjust the material of the conductive material, such as metal, graphite, etc., according to the actual product conditions.
[0090] It should also be noted that an insulating material is provided between the tube edge 12 and the arc 34 in the present application to prevent the tube edge 12 from being charged. Among them, those skilled in the art can flexibly adjust the material of the insulating material according to the actual product conditions, such as PC plastic.
[0091] In addition, the number of arcs 34 in the present application is multiple, and they correspond one to one with the lifting ribs 11; specifically, the number of arcs 34 is multiple, and they are respectively connected to the first pole piece 21 and the second pole piece 22 in the same lifting rib 11. For example, Figure 7 As shown, when the number of the lifting ribs 11 is 3, the number of the arcs 34 is also 3, and the arcs 34 correspond one to one with the lifting ribs 11; for example, Figure 8 As shown, when the number of the lifting ribs 11 is two, the number of the arcs 34 is also two, and the arcs 34 correspond to the lifting ribs 11 one by one.
[0092] Furthermore, a plurality of arc receiving elements 34 are evenly spaced apart in the circumferential direction on the outer side of the barrel edge 12 .
[0093] Preferably, if Figure 7 and Figure 8 As shown, a wire hole 13 is provided on one side of the drum edge 12 of the drum 1, and a wire passes through the wire hole 13 to connect the arc receiving 34 with the detection electrode 2, so that the arc receiving 34 can supply power to the detection electrode 2.
[0094] like Figure 7 and Figure 8 As shown, the power supply assembly 3 further includes a power supply shaft 35, which includes a support shaft 351 and a contact wheel 352. The first end of the support shaft 351 (as shown in FIG. Figure 7 The left end of the support shaft 351 is arranged on the box body 4 (not shown in the figure), and the second end of the support shaft 351 (such as Figure 7 The right end of the drum 1 is provided with a contact wheel 352, which abuts against the drum edge 12, and as the drum 1 rotates, the contact wheel 352 is configured to be connected to or disconnected from the arc 34 to supply power to or cut off power to the arc 34.
[0095] Alternatively, in one embodiment, the arc receiving member 34 is disposed on the outer wall of the drum 1, and insulating material is provided between the arc receiving member 34 and the drum; at this time, the energizing shaft 35 is also disposed below the drum 1, and the contact wheel 352 abuts against the outer wall of the drum 1. As the drum 1 rotates, the contact wheel 352 can also be connected to or disconnected from the arc receiving member 34 to supply or cut off power to the arc receiving member 34.
[0096] It should be noted that the support shaft 351 and the contact wheel 352 in this application are both made of conductive materials. Those skilled in the art can flexibly adjust the material of the conductive material, such as metal (including but not limited to steel, aluminum), based on actual product requirements. Furthermore, the support shaft 351 and the contact wheel 352 can be made of the same or different materials.
[0097] It is worth mentioning that the present application provides at least two energized shafts 35, and at least two of the energized shafts 35 are not located on the same diameter of the clothing opening 14 (at least two of the energized shafts 35 are located on different diameters of the clothing opening 14). Furthermore, at least one of the energized shafts 35 is located below the horizontal diameter of the clothing opening 14. Through this arrangement, the energized shafts 35 not only energize the receiving arc 34 through contact with the receiving arc 34, but also provide a certain degree of support for the drum 1.
[0098] In addition, the setting positions of the energized shafts 35 in the present application correspond one-to-one to the setting positions of the power receiving arcs 34 , that is, when the drum 1 stops rotating, the multiple energized shafts 35 can all be connected to the power receiving rings 34 .
[0099] In one possible implementation, Figure 7 As shown, the number of lifting ribs 11 and receiving arcs 34 is 3, and the number of energizing shafts 35 is 2. When the drum 1 is rotating, the energizing shafts 35 can intermittently contact two different receiving rings 34 to energize the two different receiving arcs 34.
[0100] In another possible implementation, Figure 8 As shown, there are two lifting ribs 11 and two receiving arcs 34 , and two power-carrying shafts 35 . When the drum 1 is rotating, the power-carrying shafts 35 can intermittently contact the two receiving arcs 34 to energize the two receiving rings 34 .
[0101] See Figure 9 Combined with Figure 7 、 Figure 8 The support shaft 351 includes a first support shaft 3511 and a second support shaft 3512, and the contact wheel 352 includes a first contact wheel 3521 and a second contact wheel 3522. The second end of the first support shaft 3511 (such as Figure 9 The right end of the second support shaft 3512 is connected to the first contact wheel 3521, and the second end of the second support shaft 3512 is connected to the first contact wheel 3521. Figure 9 Specifically, the interior of the second support shaft 3512 and the interior of the second contact wheel 3522 are both provided with through holes (not marked in the figure), and the first support shaft 3511 passes through the through holes and is connected to the first contact wheel 3521.
[0102] Preferably, a socket (not shown in the figure) is provided on the inner wall of the box body 1, and the first end of the support shaft 351 is inserted into the socket; a wire is provided in the socket, and the wire can supply power to the support shaft 351.
[0103] Preferably, if Figure 9 As shown, the first end of the support shaft 351 is sleeved with a bearing 8, which is accommodated and fixed in the socket. When the drum 1 rotates, the bearing 8 can drive the support shaft 351 to rotate, thereby reducing the wear of the contact wheel 352.
[0104] Furthermore, a locking sleeve 353 is provided on the support shaft 351. The locking sleeve 353 can adjust the installation position of the bearing 8, fix the bearing 8, and prevent the bearing 8 from deviating during rotation.
[0105] Specifically, the state in which the power-carrying shaft 35 is set in the socket is: the first end of the first support shaft 3511 contacts the bottom of the socket, the second support shaft 3512 and the locking sleeve 353 are set in the socket, and the socket is provided with a wire, which can respectively supply power to the locking sleeve 353 and the second support shaft 3512, so that the first contact wheel 3521 and the second contact wheel 3522 are respectively charged, thereby supplying power to the power receiving ring 34.
[0106] Preferably, if Figure 9 As shown, a first insulating gasket 354 is provided between the first support shaft 3511 and the second support shaft 3512, a second insulating gasket 355 is provided between the first contact wheel 3521 and the second contact wheel 3522, and a third insulating gasket 356 is provided between the second support shaft 3512 and the locking sleeve 353. The setting of the first insulating gasket 354 can separate the first support shaft 3511 and the second support shaft 3512 to prevent the two from conducting electricity to each other; the setting of the second insulating gasket 355 can separate the first contact wheel 3521 and the second contact wheel 3522 to prevent the two from conducting electricity to each other; the setting of the third insulating gasket 356 can separate the locking sleeve 353 and the second contact wheel 3522 to prevent the two from conducting electricity to each other; thereby, the locking sleeve 353, the first support shaft 3511 and the first contact wheel 3521, and the first support shaft 3512 and the second contact wheel 3522 become two groups of independent conductors, which respectively supply power to the first pole piece 21 and the second pole piece 22.
[0107] It should be noted that this application does not limit the materials of the first insulating gasket 354, the second insulating gasket 355, and the third insulating gasket 356. Those skilled in the art can flexibly adjust them according to actual product conditions. For example, the first insulating gasket 354 can be made of rubber, polyethylene plastic, etc., the second insulating gasket 355 can be made of rubber, polyethylene plastic, etc., and the third insulating gasket 356 can be made of rubber, polyethylene plastic, etc.; the materials of the first insulating gasket 354, the second insulating gasket 355, and the third insulating gasket 356 can be the same or different.
[0108] Finally, refer to Figure 2 and Figure 3 , the principle of judging whether the clothes are dried in this embodiment is explained.
[0109] Specifically, during the rotation of the drum 1, when the drum 1 rotates to a certain position, the contact wheel 352 can contact the arc 34. When the two contact wheels 352 contact any two arcs 34, the contact wheels 352 can communicate with the arc 34, thereby respectively energizing the first electrode 21 and the second electrode 22 in the two lifting ribs 34 corresponding to the arc 34. When the clothing to be tested is between the first electrode 21 and the second electrode 22, the clothing to be tested can serve as a target dielectric to be tested. During the dryness determination operation, the capacitance value between the two electrode pieces is detected, which is the clothing parameter of the clothing to be tested. During the rotation of the drum 1, the two contact wheels 352 can communicate with two different arcs 34 to energize the detection electrode 2 in the corresponding lifting rib 11, thereby obtaining the capacitance value between the detection electrode 2 in different groups, i.e., the clothing parameter of the clothing in different groups of detection electrode 2.
