[0035] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.

[0036] In the description of the embodiments of the present application, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0037] The present application embodiment provides a clothes processing device. Figures 1 to 7 , comprises a washing tub 1, a supporting unit 2, an electromagnetic coil 3 and a cooling unit 4. The washing tub 1 is rotatably supported on the supporting unit 2. The electromagnetic coil 3 is fixed relative to the supporting unit 2, and is used for electromagnetic induction heating of the washing tub 1. The cooling unit 4 is used at least for cooling the electromagnetic coil 3.

[0038] The washing tub 1 is rotatably supported on the supporting unit 2 , and the supporting unit 2 supports the washing tub 1 .

[0039] The electromagnetic coil 3 is fixed relative to the supporting unit 2, that is, the electromagnetic coil 3 will not rotate along with the washing tub 1. The electromagnetic coil 3 can perform electromagnetic induction heating on the washing tub 1 when powered on.

[0040] The heating principle of the electromagnetic coil 3 for the washing drum 1 is as follows: when powered on, the alternating current of the power supply generates an alternating magnetic field around the electromagnetic coil 3, and the magnetic flux lines generated by the electromagnetic coil 3 pass through the wall of the washing drum 1. The washing drum 1 in the alternating magnetic field will generate eddy currents, and the Joule effect of the eddy currents will increase the temperature of the washing drum 1, thereby heating the washing drum 1.

[0041] The clothes processing device of the embodiment of the present application utilizes the electromagnetic coil 3 to heat the washing drum 1, and heat conduction is performed between the heated washing drum 1 and the washing water, thereby heating the washing water. This can avoid the conduction of the washing water and improve the heating safety of the clothes processing device.

[0042] Exemplarily, the washing drum 1 is a non-porous inner drum.

[0043] That is to say, the washing drum 1 of the embodiment of the present application can hold water. When the clothing processing device is in the process of washing clothes, the washing water is contained in the washing drum 1. The washing drum 1 can also be called a hole-free inner drum, which can avoid the problem of easy dirt and grime accumulation caused by holding water in an outer barrel in the prior art.

[0044] The present application adopts the electromagnetic coil 3 to heat the washing drum 1, and an alternating magnetic field is generated by the components of the electronic circuit board. When the washing drum 1 is placed thereon, the surface of the washing drum 1 cuts the alternating magnetic lines of force and generates an alternating current (i.e., eddy current) at the bottom of the washing drum 1. The eddy current causes the carriers at the bottom of the washing drum 1 to move irregularly at high speed, and the carriers and atoms collide and rub against each other to generate heat energy, thereby heating the washing drum 1. The washing drum 1 then conducts the heat to the water in the washing drum 1, so the heat conversion rate is high, which is a direct and efficient heating method.

[0045] The specific location of the electromagnetic coil 3 is not limited, as long as it can heat the washing tub 1 .

[0046] The cooling unit 4 is at least used to cool the electromagnetic coil 3, for example, to cool the electromagnetic coil 3. Of course, in addition to cooling the electromagnetic coil 3, the cooling unit 4 can also be used to cool other heat-generating components of the clothing processing device.

[0047] The electromagnetic coil 3 is formed by, for example, winding a coil around a bobbin.

[0048] The specific location of the cooling unit 4 is not limited as long as it can cool the electromagnetic coil 3 .

[0049] In some embodiments, the clothing processing device also includes a protection module. When the temperature of the electromagnetic coil 3 of the electromagnetic heating module is too high, the protection module is started to cut off the circuit of the electromagnetic heating module, and the electromagnetic heating module stops working, thereby avoiding damage caused by the excessive temperature of the electromagnetic coil 3.

[0050] The laundry processing device provided in the embodiment of the present application includes a washing drum 1, a support unit 2, an electromagnetic coil 3 and a cooling unit 4. The washing drum 1 is heated by the electromagnetic coil 3, and heat is conducted between the washing drum 1 and the washing water, thereby heating the washing water. Therefore, the conduction of the washing water can be avoided, thereby improving the safety of the laundry processing device. Furthermore, the washing drum 1 is heated by electromagnetic induction by the electromagnetic coil 3, thereby playing a role in heating the washing drum 1. The washing drum 1 has a high heat conversion rate and heating efficiency by conducting its own heat to the washing water. In addition, by providing the cooling unit 4, when the temperature of the electromagnetic coil 3 is too high, the cooling unit 4 can be used to cool the electromagnetic coil 3, thereby avoiding the problem of damage caused by the excessive temperature of the electromagnetic coil 3, or avoiding starting the protection module of the electromagnetic heating module, thereby improving the heating performance and reliability of the electromagnetic coil 3.

[0051] In some embodiments, along the height direction of the laundry processing apparatus, the electromagnetic coil 3 is located no higher than the maximum water level allowed in the washing tub 1 .

[0052] It should be noted that the maximum water level allowed in the washing drum 1 is the maximum water level designed for the clothes treatment device, that is, the clothes treatment device will not exceed the designed maximum water level in any washing mode. Since the position of the electromagnetic coil 3 is not higher than the maximum water level allowed in the washing drum 1, that is, during the heating process, the main heating area of ​​the washing drum 1 is in contact with the washing water or is close to the washing water, therefore, during the heating process, even if the washing drum 1 does not rotate, it can avoid the local temperature of the washing drum 1 from being too high, further improving the safety of the clothes treatment device.

[0053] It should be noted that the specific material composition of the washing tub 1 in the embodiment of the present application is not limited, as long as it can generate magnetic field induced current. For example, in some embodiments, the washing tub 1 is made of a wound metal plate; in other embodiments, the washing tub 1 itself is non-conductive, and a metal layer is plated on the inner wall of the washing tub 1; or, the washing tub 1 has at least two layers of plates, and the inner layer is a metal plate.

[0054] The specific structure of the electromagnetic coil 3 is not limited, as long as it can generate an alternating magnetic field. For example, the winding method of the electromagnetic coil 3 needs to allow the magnetic lines of force to penetrate into a part of the structure of the washing tub 1.

[0055] The direction of the rotation axis of the washing drum 1 in the embodiment of the present application is not limited. For example, the rotation axis can be in the horizontal direction, in which case the laundry processing device is a drum-type laundry processing device, or in the vertical direction, in which case the laundry processing device is a pulsator-type laundry processing device. The rotation axis can also be in an inclined direction between the horizontal direction and the vertical direction, for example, in a stirring-type laundry processing device.

[0056] It should be noted that the electromagnetic coil 3 can be disposed at any appropriate position.

[0057] Exemplarily, in one embodiment, a laundry inlet is provided at the front end of the washing tub 1, and the user can take in and out clothes through the laundry inlet. Please refer to Figure 1 and Figure 2 , and the electromagnetic coil 3 is disposed below the washing tub 1.

[0058] The washing water in the washing tub 1 is located at the bottom of the washing tub 1. By disposing the electromagnetic coil 3 below the washing tub 1, it is beneficial to improve the heating efficiency of the electromagnetic coil 3.

[0059] It can be understood that the electromagnetic coil 3 can also be disposed at any position in the circumferential direction of the washing tub 1.

[0060] The electromagnetic coil 3 can be mounted on any appropriate structure. For example, in one embodiment, the laundry treatment device includes a cabinet, and the washing tub 1 is disposed in the cabinet.

[0061] The specific type of the cooling unit 4 is not limited herein. Exemplarily, in some embodiments, please refer to Figures 4 to 7 , the cooling unit 4 includes a housing 41 fixed relative to the supporting unit 2. The interior of the housing 41 has an air duct 41a and an air inlet 41b and an air outlet 41c both communicating with the air duct 41a. The electromagnetic coil 3 is disposed in the air duct 41a.

[0062] That is to say, the cooling unit 4 cools the electromagnetic coil 3 by setting the air duct 41a and using the external air flow. Specifically, by providing the air duct 41a and the air inlet 41b and the air outlet 41c both communicating with the air duct 41a inside the housing 41, the external air flow enters the air duct 41a through the air inlet 41b and flows out through the air outlet 41c. Since the electromagnetic coil 3 is disposed in the air duct 41a, the air flow flowing through the electromagnetic coil 3 can exchange heat with the electromagnetic coil 3, thereby realizing the cooling of the electromagnetic coil 3. This structure is simple, has a low cost, and has a good cooling effect.

[0063] Exemplarily, please refer to Figure 2 and Figure 3 , the laundry treatment device further includes a circuit module 32, and the circuit module 32 is electrically connected to the electromagnetic coil 3.

[0064] The specific setting position of the air inlet 41b is not limited herein. Exemplarily, in some embodiments, please refer to Figures 4 to 7 , the cooling unit 4 is disposed below the washing tub 1, and an air inlet 41b is formed on one side of the housing 41 facing the bottom of the laundry treatment device.

[0065] The cooling unit 4 is arranged below the washing drum 1. It can be understood that the temperature of the air flow between the cooling unit 4 and the washing drum 1 will be higher. By forming an air inlet 41b on the side of the shell 41 facing the bottom of the clothing processing device, it is beneficial for the external normal temperature air to enter the air duct 41a from the bottom of the clothing processing device and exchange heat with the electromagnetic coil 3, thereby improving the cooling efficiency of the cooling unit 4.

[0066] In other embodiments, the air inlet 41 b may also be disposed at the top of the housing 41 or at the end of the housing 41 along the lateral direction.

[0067] In some embodiments, see Figures 4 to 7 The housing 41 includes an upper cover 411 and a lower cover 412. The bottom wall of the lower cover 412 forms an air inlet 41b. The upper cover 411 and the lower cover 412 are connected to define an air outlet 41a and an air outlet 41c. The electromagnetic coil 3 is arranged between the air inlet 41b and the air outlet 41c.

[0068] The housing 41 includes an upper cover 411 and a lower cover 412. The housing 41 has a simple structure and is conducive to arranging the electromagnetic coil 3 in the air duct 41a.

[0069] The upper cover 411 and the lower cover 412 are connected to jointly define the air duct 41a and the air outlet 41c. For example, the upper cover 411 and the lower cover 412 are connected along the height direction of the clothing processing device, the air duct 41a extends laterally, and the air outlet 41c is formed at one end of the shell 41 along the lateral direction. The electromagnetic coil 3 is arranged between the air inlet 41b and the air outlet 41c, which is conducive to the heat exchange between the airflow flowing through the air duct 41a and the electromagnetic coil 3.

[0070] In some embodiments, please refer to Figures 4 to 7 The cooling unit 4 further includes a fan disposed above the air inlet 41b. Under the action of the fan, the external airflow enters the air duct 41a through the air inlet 41b, and flows out through the air outlet 41c after passing through the electromagnetic coil 3.

[0071] The cooling unit 4 is provided with a fan, and the fan is provided above the air inlet 41b. The fan includes, for example, a centrifugal fan, which rotates to draw the external airflow from the air inlet 41b into the air duct 41a, and cools the electromagnetic coil 3 in the air duct 41a. By providing the fan above the air inlet 41b, the cooling efficiency of the cooling unit 4 is further improved.

[0072] For example, see Figure 7 The fan includes a fan blade 43 and a motor 42 drivingly connected to the fan blade 43. The motor 42 is used to drive the fan blade 43 to rotate. The fan blade 43 is, for example, a centrifugal fan blade.

[0073] In some embodiments, see Figure 1and Figure 2 The supporting unit 2 includes a connecting bracket 21 , which is at least partially disposed at the bottom of the outer circumference of the washing tub 1 , and the housing 41 is disposed on the connecting bracket 21 .

[0074] The support unit 2 is relatively close to the washing tub 1 , so that the electromagnetic coil 3 can heat the washing tub 1 easily.

[0075] The specific structural form of the support unit 2 is not limited, and in addition to being able to provide rotational support for the washing tub 1, it can also be used to fix the housing 41. For example, the housing 41 can be fixed by providing a connecting bracket 21.

[0076] In some embodiments, see Figure 1 and Figure 2 Along the horizontal direction of the clothing processing device, the connecting bracket 21 includes a first sub-bracket 211 and a second sub-bracket 212 arranged on both sides of the central axis of the washing drum 1, one end of the shell 41 is connected to the first sub-bracket 211, and the other end is connected to the second sub-bracket 212.

[0077] Specifically, along the lateral direction of the laundry processing apparatus, the connecting bracket 21 includes a first sub-bracket 211 and a second sub-bracket 212 that are symmetrically arranged.

[0078] Of course, in other embodiments, along the transverse direction of the clothes processing apparatus, the first sub-bracket 211 and the second sub-bracket 212 may not be symmetrically arranged.

[0079] Exemplarily, the first sub-bracket 211 and the second sub-bracket 212 are an integrated structure. The integrated first sub-bracket 211 and the second sub-bracket 212 can reduce the number of parts, reduce assembly time, and improve assembly efficiency.

[0080] Of course, the first sub-bracket 211 and the second sub-bracket 212 may also be split structures. The split first sub-bracket 211 and the second sub-bracket 212 are conducive to forming a desired structure.

[0081] One end of the shell 41 is connected to the first sub-bracket 211 , and the other end is connected to the second sub-bracket 212 . The connection structure is simple and helps to ensure the connection stability of the shell 41 .

[0082] The first sub-bracket 211 and the second sub-bracket 212 are symmetrically arranged along the transverse direction of the clothing processing device, which is conducive to realizing the symmetrical arrangement of the shell 41 along the transverse direction of the clothing processing device, thereby realizing the symmetrical arrangement of the electromagnetic coil 3 along the transverse direction of the clothing processing device, thereby improving the heating efficiency.

[0083] It should be noted that the housing 41 may be directly connected to the connection bracket 21 or indirectly connected to the connection bracket 21. For example, in some embodiments, the cooling unit 4 further includes an adapter 44, and the housing 41 is connected to the connection bracket 21 through the adapter 44.

[0084] Since the first sub-bracket 211 and the second sub-bracket 212 are arranged in an arc shape on the outer peripheral side of the washing drum 1, in order to facilitate the connection between the shell 41 and the first sub-bracket 211 and the second sub-bracket 212, an adapter 44 is provided so that the shell 41 is connected to the connecting bracket 21 through the adapter 44.

[0085] In some embodiments, see Figure 7 The shape of the electromagnetic coil 3 matches the shape of the air duct 41a. That is, the shape of the electromagnetic coil 3 is substantially the same as or identical to the shape of the air duct 41a.

[0086] By setting the shape of the electromagnetic coil 3 to match the shape of the air duct 41a, or in other words, by setting the shape of the air duct 41a to match the shape of the electromagnetic coil 3, the space in the air duct 41a can be fully utilized, and the airflow in the air duct 41a is facilitated to fully contact the electromagnetic coil 3, thereby making the structure of the clothing processing equipment compact and also helping to improve the cooling efficiency of the cooling unit 4.

[0087] In some embodiments, see Figures 1 to 7 The electromagnetic coil 3 is in an arc shape that matches the outer wall of the washing tub 1 .

[0088] By setting the electromagnetic coil 3 to be in an arc shape that matches the outer wall of the washing tub 1, for example, winding the electromagnetic coil 3 into an arc shape with the same or substantially the same curvature as the outer wall of the washing tub 1, the heating efficiency of the electromagnetic coil 3 is improved.

[0089] In some embodiments, see Figure 1 and Figure 2 At least part of the shell 41 is in an arc shape that matches the outer wall of the washing tub 1 .

[0090] At least part of the shell 41 is in an arc shape that matches the outer wall of the washing drum 1 , which may mean that a partial area of ​​the shell 41 is in an arc shape that matches the outer wall of the washing drum 1 , or the entire area of ​​the shell 41 is in an arc shape that matches the outer wall of the washing drum 1 .

[0091] By setting the shell 41 to be in an arc shape that is compatible with the outer wall of the washing drum 1, for example, setting the shell 41 to be in an arc shape that is the same as or approximately the same as the curvature of the outer wall of the washing drum 1, it is beneficial to wind the electromagnetic coil 3 into an arc shape that is the same as or approximately the same as the curvature of the outer wall of the washing drum 1. At this time, the shape of the air duct 41a is also compatible with the shape of the electromagnetic coil 3. In this way, the space in the air duct 41a can be fully utilized, and it is beneficial to make the airflow in the air duct 41a fully contact with the electromagnetic coil 3, thereby making the structure of the clothing processing device compact while also helping to improve the cooling efficiency of the cooling unit 4 and the heating efficiency of the electromagnetic coil 3.

[0092] Exemplarily, the upper cover 411 and the lower cover 412 of the shell 41 are designed in the flow path pattern of an Archimedean spiral, and the electromagnetic coil 3 is consistent in shape with the shell 41 , and is designed as an arc along the outer peripheral side of the washing tub 1 as a whole.

[0093] In some embodiments, the gap between the electromagnetic coil 3 and the washing tub 1 is 2 mm-30 mm, for example, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 10 mm, 15 mm, 16 mm, 22 mm, 26 mm, 27 mm, 28 mm, 29 mm or 30 mm, etc.

[0094] The gap between the electromagnetic coil 3 and the washing tub 1 is Figure 1 H shown in .

[0095] It is understandable that the gap between the electromagnetic coil 3 and the washing drum 1 needs to be guaranteed. If the gap between the electromagnetic coil 3 and the washing drum 1 is too large, the electromagnetic coil 3 cannot sense the washing drum 1 and the heating function cannot be started. If the gap between the electromagnetic coil 3 and the washing drum 1 is too small, there are clothes and water in the washing drum 1, and the washing drum 1 shakes when the clothing processing equipment is running, and there is a situation where the electromagnetic coil 3 is easily touched and the electromagnetic coil 3 is damaged.

[0096] Therefore, by setting the gap between the electromagnetic coil 3 and the washing tub 1 to 2 mm-30 mm, it is not only conducive for the electromagnetic coil 3 to smoothly sense the washing tub 1 and start the heating function, but also can ensure the heating efficiency of the electromagnetic coil 3. In addition, to a certain extent, it can also prevent the washing tub 1 from touching and damaging the electromagnetic coil 3 during the use of the clothes processing device.

[0097] In some embodiments, the gap between the electromagnetic coil 3 and the washing tub 1 is 8 mm-25 mm, for example, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, 21 mm, 22 mm, 23 mm, 24 mm or 25 mm, etc.

[0098] By setting the gap between the electromagnetic coil 3 and the washing tub 1 to 8mm-25mm, the heating efficiency of the electromagnetic coil 3 can be guaranteed and, to a certain extent, the situation in which the washing tub 1 touches and damages the electromagnetic coil 3 during use of the clothing processing device can be avoided.

[0099] Preferably, the gap between the electromagnetic coil 3 and the washing tub 1 is 15 mm.
