Among them, the bearing seat in the drum washing machine is an important force receiving component of the washing machine, and the bearing is installed in the bearing seat to realize high-speed rotation of the inner drum.

[0004] In the prior art, when the drum washing machine is used in a region with low temperature, the lubricating grease in the bearing seat has poor flowability, which easily causes large starting torque of the washing machine, high product energy consumption, and problems such as belt slip noise during the starting process. INVENTION CONTENTS

[0005] The utility model aims at providing a clothes treatment equipment to solve the problem that water vapor is easily accumulated in the bearing seat in the prior art and affects the working of the bearing.

[0006] To solve the above technical problems, the utility model adopts the following technical scheme:

On the other hand, since the heating member is also exposed to the rear surface of the outer drum, the heat of the heating member needs to be transmitted through multiple layers of materials or structures to reach the bearing seat, thereby reducing the heat transfer path between the heating member and the drum assembly, so that the heat generated by the heating member during heating can be more transmitted to the bearing seat.

[0011] In some embodiments of the present application, a laundry treating apparatus is provided, wherein the heating member is annular and disposed circumferentially around the rear end of the bearing seat.

[0012] Another technical solution in the above technical solution has the following advantages or beneficial effects: by configuring the heating member into an annular structure, the annular heating member can heat around the entire circumference of the rear end of the bearing seat, which is conducive to uniformly distributing heat inside the bearing seat, thereby avoiding the situation of local overheating or insufficient heating of the bearing seat, so that the lubricating grease in the bearing seat can be fully heated and improved in flowability inside the entire bearing seat.

At the same time, since the heating member is sleeved on the boss, it can be easily removed for maintenance or replacement through simple disassembly operation, thereby making the maintenance and replacement of the heating member more simple. Moreover, the annular heating member can be closely sleeved on the boss, and the heat can be more stably transmitted to the inside of the bearing seat.

[0015] In some embodiments of the present application, a laundry treating apparatus is provided, wherein the annular structure of the heating member has a gap, and the heating member can be elastically expanded at the gap to adjust the inner diameter of the heating member to adapt the heating member to the boss.

[0049] Figure 1 The schematic diagram of the clothes processing equipment of an embodiment of the present application.

[0050] As Figure 1 Indicated, in some embodiments, the clothes processing equipment can include cabinet 1.Cabinet 1 can be the overall structure outside the washing machine, and cabinet 1 is a hollow structure, wherein other component structures of the washing machine can be arranged, such as circuit structure (not shown in the figure), air duct structure (not shown in the figure), driving mechanism (not shown in the figure) and drain valve assembly (not shown in the figure) and the like.

[0051] It needs to be explained that the clothes processing equipment can be a clothes dryer, a washing and drying integrated machine or a heat pump washing machine and other clothes processing equipment.

[0052] As Figure 1As shown, in some embodiments, the door 11 and the box body 1 can be connected by a hinge, and the door 11 can rotate around the axis of the hinge, thereby realizing the opening and closing of the door 11.

[0053] Figure 2 for Figure 1 A schematic diagram of the rear side of the inner and outer cylinders.

[0054] like Figure 1 and Figure 2 As shown, in some embodiments, the drum assembly can be disposed inside the housing 1. A drum opening is formed on the front end face of the drum assembly, which faces the clothing inlet and the door 11 of the housing 1. A clothing processing chamber is formed inside the drum assembly. The drum opening can communicate with the clothing processing chamber. The clothing processing chamber can serve as a storage location for clothing washing, drying, and other processing procedures. After the door 11 is opened, clothing can be sequentially placed into the clothing processing chamber inside the drum assembly through the clothing inlet on the front side of the housing 1 and the drum opening for drying.

[0055] In some embodiments, the drum assembly is rotatably disposed within the housing 1. During the drying process of clothes in the clothes processing chamber, the drum assembly can drive the clothes in the clothes processing chamber to rotate, thereby improving the drying uniformity and drying efficiency of the clothes.

[0056] like Figure 2 As shown, in some embodiments, the tub assembly may include an outer tub 12. The outer tub 12 may be disposed within the housing 1. The outer tub 12 is fixed relative to the interior of the housing 1. The outer tub 12 is a shell structure with a nozzle, the nozzle of which faces the interior of the housing 1 at the front side. The nozzle of the outer tub 12 may be configured as a clothes inlet 101. The outer tub 12 is constructed as a tub for containing washing water, that is, the internal space of the outer tub 12 can be used to hold washing liquid, such as water.

[0057] In some embodiments, the tubular assembly may include an inner tub (not shown). The inner tub is rotatably disposed within the internal space of the outer tub 12, and a garment handling chamber may be formed within the inner tub for holding garments to be washed. The opening of the inner tub may be arranged directly opposite the opening of the outer tub 12 and the garment inlet. Therefore, garments can sequentially enter the garment handling chamber from the garment inlet 101, the opening of the outer tub 12, and the opening of the inner tub.

[0058] In some embodiments, the outer drum 12 and the inner drum can be arranged coaxially inside and outside. A hole may be provided on the outer wall of the inner drum, allowing water from the outer drum 12 to enter the inner drum through the hole to wash the clothes in the inner drum's clothes handling chamber. Simultaneously, during clothes drying, air from the inner drum's clothes handling chamber can also enter the interior space of the outer drum 12 through the hole.

[0059] In some embodiments, a drive device (not shown in the figure) may be provided inside the housing 1. The drive device may be located outside the outer drum 12, and the output end of the drive device may extend from the center of the rear end of the outer drum 12 into the interior of the outer drum 12 and be connected to the inner drum for transmission, so as to drive the inner drum to rotate relative to the outer drum 12, thereby washing the clothes in the inner drum.

[0060] Figure 3 for Figure 2 A cross-sectional view of point AA.

[0061] like Figure 3 As shown, in some embodiments, the garment handling device may include a rotating shaft 22. The rotating shaft 22 is rotatably mounted on the outer drum 12. One end of the rotating shaft 22 is connected to a drive device, and the other end of the rotating shaft 22 is connected to the inner drum. When the rotating shaft 22 rotates, it can drive the inner drum to rotate.

[0062] like Figure 3 As shown, in some embodiments, the garment handling device may include a connecting arm 13. The connecting arm 13 may be disposed on the inner drum, and the connecting arm 13 may be connected to a rotating shaft 22, which may drive the connecting arm 13 and the inner drum to rotate synchronously.

[0063] Figure 4 for Figure 2 A cross-sectional schematic diagram of the bearing assembly.

[0064] like Figure 4 As shown, in some embodiments, the garment handling apparatus may include a bearing assembly 2. The bearing assembly 2 may be disposed on the back of the outer cylinder 12. The bearing assembly 2 may be used to support the rotating shaft 22.

[0065] like Figure 3 and Figure 4 As shown, in some embodiments, the bearing assembly 2 may include a bearing seat 21. The bearing seat 21 may be disposed on the rear wall of the outer cylinder 12. The bearing seat 21 may have a mounting through hole 201. The mounting through hole 201 may extend through both the front and rear ends of the bearing seat 21. The rotating shaft 22 may pass through the mounting through hole 201. The bearing seat 21 may be fixedly disposed on the back side of the outer cylinder 12 and used to support the rotating shaft 22. The rotating shaft 22 is rotatably disposed within the mounting through hole 201, and under the drive of the driving device, the rotating shaft 22 may rotate relative to the bearing seat 21 to drive the inner cylinder to rotate.

[0066] In some embodiments, a mounting hole 101 may be provided at the center of the rear side of the outer cylinder 12. The bearing seat 21 may be installed in the mounting hole 101. In this way, the bearing seat 21 can be fixed at the center of the outer cylinder 12.

[0067] like Figure 2As shown, in some embodiments, the bearing seat 21 can be provided with a connecting hole 203, which can be used to adapt with the outer cylinder 12 and can be penetrated by a connecting member to fix the bearing seat 21 at the center of the outer cylinder 12.

[0068] As shown, in some embodiments, the bearing device 2 can include a bearing 20. The bearing 20 can be installed in the mounting through hole 201. The bearing 20 can be sleeved on the rotating shaft 22. Among them, the bearing 20 can be supported between the bearing 20 and the bearing seat 21 to reduce the wear between the rotating shaft 22 and the bearing seat 21. Figure 4

[0069] As shown, in some embodiments, the bearing device 2 can include a heating member 3. The heating member 3 can be provided on the bearing seat 21. The heating member 3 can be configured to heat the bearing seat 21 to transmit heat to the bearing 20 through the bearing seat 21. Figure 3 Figure 4 Currently, the main products on the market are impeller washing machines and drum washing machines. Among them, the bearing seat 21 in the drum washing machine is an important force receiving component of the washing machine, and the bearing 20 is installed in it to realize the high-speed rotation of the inner cylinder.

[0070] Among them, the bearing 20 is usually coated with a layer of lubricating grease. Since the lubricating grease is in a solidified state at low temperature, its flowability is poor, which can easily cause the washing machine to have a large starting torque, resulting in high product energy consumption, and the clothes treatment equipment has a large starting torque during the starting process, which can cause the belt to slip and produce noise.

[0071] In the present application, by providing a heating member 3 on the bearing seat 21, the heating member 3 can heat the bearing seat 21 and its interior, and the heat can be transmitted to the bearing 20 through the bearing seat 21, thereby heating the lubricating grease inside the bearing seat 21, reducing the viscosity of the lubricating grease and enhancing its flowability. This is conducive to reducing the frictional resistance between the bearing 20 and the rotating shaft 22, reducing the torque of the clothes treatment equipment during startup, and reducing energy consumption. Moreover, it can reduce the risk of belt slippage and noise, and since the starting torque is reduced, the vibration and noise of the clothes treatment equipment during the starting process are also reduced, improving the user's experience.

[0072] On the other hand, the heating member 3 can make the lubricating grease in the bearing seat 21 have good flowability. In a low-temperature environment, by heating the bearing seat 21 through the heating member 3, the lubricating grease can maintain appropriate flowability during the operation of the clothes treatment equipment, thereby effectively reducing the wear of the bearing 20 and improving the operation stability and reliability of the washing machine.

[0073]

[0074] ​​​It should be noted that heating the bearing housing 21 by adding heating element 3 in this application will consume a certain amount of electrical energy. However, compared with the additional energy consumption caused by the large starting torque, its energy-saving effect is more significant, making the clothing processing equipment more in line with the current development trend of energy conservation and environmental protection.

[0075] Figure 5 for Figure 2 A three-dimensional schematic diagram; Figure 6 for Figure 5 An exploded image.

[0076] like Figure 5 and Figure 6 As shown, in some embodiments, the rear end face of the bearing housing 21 may be exposed on the back side of the outer cylinder 12. The heating element 3 may be disposed on the rear end of the bearing housing 21, and the heating element 3 may be exposed on the back side of the outer cylinder 12.

[0077] Specifically, the rear end face of the bearing housing 21 is exposed on the back side of the outer cylinder 12. That is, the rear end portion of the bearing housing 21 is not completely enclosed by the outer cylinder 12, but rather a portion is directly exposed outside the back side of the outer cylinder 12. Since the heating element 3 is installed on the rear end of the bearing housing 21, workers can install the heating element 3 onto the bearing housing 21 without disassembling too many parts, simplifying the installation process. On the other hand, the fact that the heating element 3 is also exposed on the back side of the outer cylinder 12 avoids the need for the heat from the heating element 3 to be transferred through multiple layers of materials or structures to the bearing housing 21. This reduces the heat transfer path between the heating element 3 and the bearing housing, allowing more of the heat generated by the heating element 3 during the heating process to be transferred to the bearing housing 21.

[0078] In some other embodiments, the rear end face of the bearing housing 21 may also be flush with the back face of the outer cylinder 12. The heating element 3 may be embedded inside the bearing housing 21, and the heat generated by the heating element 3 during the heating process can be transferred to the bearing housing 21.

[0079] Figure 7 for Figure 1 A schematic diagram of the heating element.

[0080] like Figure 6 and Figure 7 As shown, in some embodiments, the heating element 3 may be annular. The heating element 3 may be circumferentially arranged around the rear end of the bearing housing 21.

[0081] Specifically, by configuring the heating element 3 into a ring structure, the ring-shaped heating element 3 can heat the entire circumference around the rear end of the bearing housing 21, which helps to distribute the heat evenly inside the bearing housing 21, thereby avoiding local overheating or insufficient heating of the bearing housing 21, so that the lubricating grease inside the bearing housing 21 can be fully heated and its fluidity improved throughout the entire bearing housing 21.

[0082] Furthermore, since the annular heating element 3 can surround the entire circumference of the rear end of the bearing housing 21, the heating area of ​​the heating element 3 on the bearing housing 21 can be larger, enabling faster heat transfer to the interior of the bearing housing 21. Compared to point or linear heating methods, annular heating can more effectively utilize the power of the heating component and improve heating efficiency. Moreover, the annular heating element 3 can be more compactly surrounded at the rear end of the bearing housing 21, making full use of the internal space of the garment processing equipment.

[0083] In some other embodiments, the heating element 3 may also be configured as, for example, a rectangular, circular or block of various shapes.

[0084] In some embodiments, the heating element 3 can be designed as a ring structure composed of multiple segments. Each segment can be heated independently, thereby achieving precise heating of different areas of the bearing housing 21. This further increases the flexibility and controllability of the heating process.

[0085] In some embodiments, the heating element 3 may consist of multiple strip heating elements. These strip elements are arranged circumferentially along the rear end of the bearing housing 21 and are closely fitted together. By adjusting the number and arrangement of the strip heating elements, flexible control of the heating area and heating intensity can be achieved.

[0086] In some embodiments, the heating element 3 can be a matrix structure composed of multiple point heating elements. Each point heating element can be independently controlled for heating, thereby achieving flexible control over different areas of the bearing housing 21.

[0087] In some embodiments, the heating element 3 may also be a PTC.

[0088] In some other embodiments, the heating element 3 may also be configured as a heating film, which may be attached to the outer surface of the bearing housing 21 or attached to the wall of the mounting through hole 201 of the bearing housing 21.

[0089] In some other embodiments, the heating element 3 may be a resistance heating wire.

[0090] like Figure 4 and Figure 6 As shown, in some embodiments, the bearing housing 21 may be provided with a boss 26. The boss 26 may be raised and disposed at the rear end of the bearing housing 21, and the boss 26 may be exposed on the back side of the outer cylinder 12. The heating element 3 may be sleeved on the boss 26.

[0091] The bearing housing 21 is provided with a boss 26, and the heating element 3 is sleeved on the boss 26, so that the heating element 3 can be exposed on the back of the outer cylinder 12.

[0092] Specifically, since the boss 26 can serve as a reference surface for the installation of the heating element 3, the provision of the boss 26 can provide the heating element 3 with an accurate positioning and fixing point, thus playing a role in simplifying the installation process and improving the installation accuracy. Meanwhile, since the heating element 3 is sleeved on the boss 26, it can be removed for maintenance or replacement through a simple dismounting operation, making the maintenance and replacement of the heating element 3 simpler. Moreover, the annular heating element 3 can be closely sleeved on the boss 26, and heat can be more stably transferred to the inner side of the bearing seat 21.

[0093] As shown in Figure 4 and Figure 5 indicated, in some embodiments, the boss 26 can be in a cylindrical shape. The size of the annular heating element 3 can be adapted to the size of the boss 26, and the radially inner surface of the annular structure of the heating element 3 can be closely attached to the surface of the boss 26.

[0094] In some embodiments, the boss 26 can be in a conical shape. The conical structure can make it easier to align and fix the heating element 3 when sleeving, and the conical structure can also provide a certain guiding effect, thus simplifying the installation process.

[0095] In some embodiments, the boss 26 can be designed in a polygonal shape. This can provide more positioning points and fixing surfaces for the installation of the heating element 3, thus enhancing the stability of the installation structure of the heating element 3.

[0096] In some embodiments, the outer surface of the boss 26 can be designed in a threaded shape. This can enable the heating element 3 to be fixed on the boss through threaded connection, thus improving the stability and reliability of the connection.

[0097] In some embodiments, the boss 26 can be designed in a wavy or irregular shape. This can increase the contact area between the heating element 3 and the boss, thus improving the heat transfer efficiency.

[0098] In some embodiments, the boss 26 can be integrally formed with the bearing seat 21. The boss 26 can be provided in a protruding manner from the rear end surface of the bearing seat 21.

[0099] In other embodiments, a recess (not shown in the figure) can be recessed on the bearing seat 21. The size of the recess can be adapted to the shape and size of the heating element 3. The heating element 3 can be installed in the recess.

[0100] As shown in Figure 6 and Figure 7 indicated, in some embodiments, the annular structure of the heating element 3 can have a notch 301. The heating element 3 can be elastically expanded at the notch 301 to adjust the inner diameter of the heating element 3 so that the heating element 3 is adapted to the boss 26.

[0101] Specifically, the heating element 3 is provided with a notch 301, so that the annular structure of the heating element 3 is discontinuous circular. The notch 301 on the annular structure of the heating element 3 enables it to have the ability to elastically open, not only enabling the heating element 3 to better fit different sizes and shapes of the boss 26, increasing the compatibility between the heating element 3 and the boss 26, but also enabling the heating element 3 to be easily sleeved on the boss 26 without the need for complex adjustment or modification of the heating element 3 or the boss 26, so that the installation process becomes simpler and faster, and the installation difficulty and cost are reduced.

[0102] On the other hand, the notch 301 of the heating element 3 enables it to have the ability to elastically open, so that the heating element 3 can be closely fitted on the boss 26, which is conducive to the effective transmission of heat and can further enhance the connection stability of the heating element 3 and the boss 26. During the heating process, the heating element 3 can better withstand thermal stress and deformation caused by temperature changes, thereby maintaining the stability of its shape and position.

[0103] In some embodiments, the heating element 3 can be provided with a wiring end. The wiring end is used to electrically connect with the electric control assembly, so as to power on or power off the heating element 3.

[0104] As shown in Figure 7 some embodiments, the two sides of the notch 301 of the heating element 3 can be respectively provided with a first connecting end 31 and a second connecting end 32. The wiring end can include a first wiring end 33 and a second wiring end 34. The first wiring end 33 can be arranged on the first connecting end 31 and used to connect with one end of the electric control assembly. The second wiring end 34 can be arranged on the second connecting end 32 and used to connect with the other end of the electric control assembly.

[0105] Among them, by arranging the first wiring end 33 and the second wiring end 34 on the first connecting end 31 and the second connecting end 32 respectively, the first wiring end 33 is arranged on the first connecting end 31 and the second wiring end 34 is arranged on the second connecting end 32. The first wiring end 33 can be connected with one end of the electric control assembly of the clothes treatment equipment, and the second wiring end 34 can be connected with the other end of the electric control assembly of the clothes treatment equipment, which can simplify the circuit layout of the heating element 3 and the electric control assembly, without the need for additional connection components such as wiring posts or wiring clips on the heating element 3, so that the heating element 3 and the electric control assembly can be easily connected, reducing the complexity and cost of circuit design.

[0106] In some embodiments, the first wiring end 33 is connected with the positive electrode of the electric control assembly, and the second wiring end 34 is connected with the negative electrode of the electric control assembly.

[0107] Figure 8 For Figure 2 a three-dimensional schematic view of the bearing device; Figure 9 For Figure 8exploded view.

[0108] As Figure 8 and Figure 9 shown, in some embodiments, the bearing 20 can include a first bearing 23. The first bearing 23 can be arranged at the front end of the mounting through hole 201, and the first bearing 23 can be arranged on the rotating shaft 22.

[0109] Specifically, the inner ring of the first bearing 23 can be arranged on the surface of the rotating shaft 22, the outer ring of the first bearing 23 can be nested in the hole wall of the mounting through hole 201, and the first bearing 23 can be used to support the rotating shaft 22 and reduce the wear between the rotating shaft 22 and the bearing seat 21. When the heating element 3 is working, the heat generated by the heating element 3 can be transmitted to the first bearing 23 through the bearing seat 21, so that the viscosity of the lubricating grease at the first bearing 23 is reduced and the fluidity is enhanced, the frictional resistance between the first bearing 23 and the rotating shaft 22 is reduced, and the torque of the clothes treatment equipment at the start is effectively reduced.

[0110] As Figure 9 shown, in some embodiments, the clothes treatment equipment can include an oil seal 25. The oil seal 25 can be arranged at the front end in the mounting through hole 201. The oil seal 25 can be located on the front side of the first bearing 23, and the oil seal 25 can be in contact with the front end surface of the first bearing 23 to seal the connection between the outer barrel 12 and the bearing seat 21.

[0111] The oil seal 25 is arranged at the front end of the first bearing 23, that is, on the side of the first bearing 23 close to the clothes treatment cavity, and the oil seal 25 is in contact with the front end surface of the first bearing 23, which can prevent impurities, moisture and the like from entering the inside of the first bearing 23, thereby protecting the inside of the first bearing 23 and the bearing seat 21 from damage, facilitating prolonging the service life of the bearing 20, and improving the reliability and stability of the equipment.

[0112] It should be noted that the oil seal 25 is arranged on the rotating shaft 22, and the oil seal 25 is also provided with lubricating grease, and the oil seal 25 is in contact with the front end surface of the first bearing 23, so that when the heating element 3 is working, heat can be directly transmitted to the oil seal 25 through the bearing seat 21, or can be transmitted to the oil seal 25 through the first bearing 23, so that the lubricating grease can maintain appropriate fluidity, and the wear between the oil seal 25 and the rotating shaft 22 and the torque of the clothes treatment equipment at the start are reduced.

[0113] As Figure 8 and Figure 9 shown, in some embodiments, the bearing 20 can include a second bearing 24. The second bearing 24 can be arranged at the rear end of the mounting through hole 201. The second bearing 24 can be arranged on the rotating shaft 22, and the second bearing 24 can be arranged on the rear side of the first bearing 23 at intervals.

[0114] Specifically, the inner ring of the second bearing 24 is sleeved on the surface of the rotating shaft 22, and the outer ring of the second bearing 24 is nested in the hole wall of the mounting hole 201. Moreover, the first bearing 23 and the second bearing 24 are arranged on the rotating shaft 22 in a spaced manner, which can improve the stability of the support of the rotating shaft 22.

[0115] Further, since the second bearing 24 is provided with lubricating grease, when the heating element 3 works, the heat generated by the heating element 3 can be transmitted to the second bearing 24 through the bearing seat 21, so that the viscosity of the lubricating grease at the second bearing 24 is reduced, the fluidity is enhanced, the frictional resistance between the second bearing 24 and the rotating shaft 22 is reduced, and the problem of high energy consumption caused by large starting torque is effectively improved.

[0116] Figure 10 For Figure 3 A local enlarged view of the A part.

[0117] As Figure 10 shown, in some embodiments, the mounting hole 201 can extend into the boss 26. Among them, by extending the mounting hole 201 into the boss 26, and arranging the second bearing 24 in the boss 26, the space of the boss 26 can be effectively utilized, so that the layout of the whole bearing seat 21 is more compact.

[0118] In some embodiments, the mounting hole 201 can extend through the rear end surface of the boss 26.

[0119] In some embodiments, the second bearing 24 can be arranged at the mounting hole 201 in the boss 26. The second bearing 24 and the heating element 3 can be arranged on the inner and outer sides of the boss 26 respectively.

[0120] Specifically, the inner side of the boss 26 is provided with a mounting hole 201, and the second bearing 24 is arranged at the mounting hole 201 on the inner side of the boss 26. Correspondingly, the heating element 3 is sleeved on the radial outer side of the boss 26. When the heating element 3 works, the heat can be transmitted to the second bearing 24 through the side wall of the boss 26 more quickly and efficiently, reducing the loss of heat in the transmission process, and improving the heat conduction efficiency of the heating element 3 to the lubricating grease in the bearing seat 21.

[0121] Figure 11 A control circuit structure diagram of a clothes treatment apparatus according to an embodiment of the present application.

[0122] As Figure 11 shown, in some embodiments, the clothes treatment apparatus can include a temperature sensor 4. The temperature sensor 4 can be arranged on the bearing seat 21. The temperature sensor 4 is used to sense the temperature of the bearing seat 21. By arranging the sensor on the bearing seat 21, the sensor can sense the temperature of the bearing seat 21 in real time and accurately.

[0123] AsFigure 11 As shown, in some embodiments, the clothes treatment apparatus can include a controller 5. The controller 5 can be electrically connected with the temperature sensor 4 and the heating member 3, respectively, to control the start or stop of the heating member 3 according to the temperature of the bearing seat 21.

[0124] Wherein, through the electrical connection of the controller 5 with the temperature sensor 4 and the heating member 3, respectively, the automatic control of the start or stop of the heating member 3 is realized. Specifically, the controller 5 can receive the temperature information of the bearing seat 21 from the temperature sensor 4, and then can automatically adjust the working state of the heating member 3 according to the actual temperature of the bearing seat 21, so that the bearing seat 21 can be maintained within the appropriate working temperature range, avoiding the lubricating grease inside the bearing seat 21 to be poor in flowability due to low temperature, which can easily cause the problems of high product energy consumption, large starting noise and the like caused by large starting torque of the apparatus.

[0125] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical scope disclosed in the present application, which should be covered within the protection scope of the present application. Therefore, the scope of the present application is limited only by the appended claims.
