Detailed Embodiments

[0032] In order to be able to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the following will further describe the solution of the present utility model. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.

[0033] Many specific details are set forth in the following description in order to fully understand the present utility model, but the present utility model can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0034] A laundry treatment device, such as a dryer, generally includes a rotatable inner tub, a bearing member (such as a housing) for carrying the inner tub, and a driving device for driving the inner tub to rotate relative to the bearing member. The inner tub is used to hold the laundry to be treated (such as to be dried). The inner tub rotates relative to the bearing member, so as to dry the laundry in the inner tub.

[0035] Since the inner tub is a rotating component and it is difficult to supply power to it. If electrical components (such as a humidity sensor, etc.) are installed on the inner tub, a separate external power supply arrangement needs to be made for the electrical components, and the external power supply arrangement is relatively difficult and the cost is high. Therefore, in the existing dryers, the humidity sensor is generally arranged on the filter screen assembly that does not rotate with the inner tub. However, in this structure, the laundry in the tub cannot directly contact the humidity sensor, resulting in poor detection sensitivity and accuracy.

[0036] Based on this, referring to Figures 1 to 4 As shown, a laundry treatment device provided by some embodiments of the present utility model includes a bearing member, an inner tub 2, a driving device, a power generation assembly and an electrical component.

[0037] Among them, the inner tub 2 is used to hold the laundry to be treated (such as to be dried, to be washed). The inner tub 2 is installed on the bearing member. The bearing member can specifically be components such as a housing, an outer tub, etc. The bearing member can be a stationary member, which is used to provide support for the inner tub 2, so that the inner tub 2 can rotate relative to the bearing member, thereby drying or washing the laundry placed in the inner tub 2, etc.; the driving device is connected to the inner tub 2 and is used to drive the inner tub 2 to rotate relative to the bearing member; specifically, the driving device can include a power source (such as a driving motor) and a transmission shaft 3 connected to the power source and other structures. The power source provides rotational power for the inner tub 2 through the transmission shaft 3.

[0038] Among them, the power generation assembly is arranged outside the bottom of the inner tub 2. The power generation assembly includes a stator part 4 and a rotor part 5. The rotor part 5 is fixed to the inner tub 2, and the rotor part 5 generates electric energy as it rotates relative to the stator part 4 along with the inner tub 2; the electrical component is arranged on the inner tub 2 and is electrically connected to the rotor part 5; specifically, the electrical component can be a humidity sensor 23, a lighting lamp, etc. The electrical component can be arranged in the inner cavity of the inner tub 2 according to needs, such as fixed on the inner wall of the inner tub 2; of course, it can also be arranged at other positions such as on the outer wall of the inner tub 2 according to needs, as long as the electrical component can rotate together with the inner tub 2; the electrical component can be electrically connected to the rotor part 5 located outside the inner tub 2 through a conductive connection method such as a wire.

[0039] Specifically, by arranging a power generation component outside the inner tub 2, with the rotor part 5 of the power generation component fixed to the inner tub 2, when the inner tub 2 rotates relative to the bearing component under the drive of the driving device, the rotor part 5 of the power generation component rotates relative to the stator part 4 together with the inner tub 2, thereby generating electric energy. In this way, by using the generator method, the mechanical energy of the rotation of the inner tub 2 is converted into electric energy, and then the electric energy is introduced to the electrical components arranged on the inner tub 2. With such an arrangement, it is possible to directly arrange electrical components (such as the humidity sensor 23) in the inner cavity of the inner tub 2 and use the power generation component to supply power to the electrical components, so as to directly contact the clothes in the tub with the electrical components (such as the humidity sensor 23) to detect the humidity of the clothes in the tub, improve the sensitivity and accuracy of detection, and is conducive to detecting lower moisture content, thus solving the problem that the current humidity sensor arranged on the filter screen component cannot directly detect the humidity.

[0040] In a specific implementation, the stator part 4 of the power generation component can be fixed to the bearing component and arranged corresponding to the rotor part 5. Specifically, the inner tub 2 is a rotating part. Compared with the inner tub 2, the bearing component is a stationary part. By fixing the stator part 4 of the power generation component to the stationary part and the rotor part 5 to the rotating part, when the inner tub 2 rotates relative to the bearing component, the rotor part 5 can rotate relative to the stator part 4, thereby generating electric energy. It should be noted that the bearing component can specifically be a housing or an outer tub for bearing the inner tub 2, etc. The stator part 4 can specifically be arranged at a position corresponding to the bottom of the inner tub 2 inside the housing or the outer tub. For the specific setting position of the stator part 4, it is not limited to the above specific limitations and can be reasonably set according to the actual product structure, as long as the stator part 4 is arranged outside the inner tub 2 and on a component that does not rotate together with the inner tub 2.

[0041] In a specific embodiment, referring to Figure 1 and Figure 2 as shown, the power generation component includes a stator part 4 and a rotor part 5. The stator part 4 is fixed to the bearing component, and the rotor part 5 is fixed to the inner tub 2. The rotor part 5 generates electric energy as it rotates relative to the stator part 4 together with the inner tub 2; the electrical component is arranged in the inner cavity of the inner tub 2 and is electrically connected to the rotor part 5 located outside the inner tub 2 through a wire 6.

[0042] It should be noted that the power generation component in the embodiments of the present utility model is arranged based on the power generation principle of a generator. The working principle of a generator is based on the law of electromagnetic induction and the law of electromagnetic force, using magnetic field induction to generate electromotive force, thereby converting mechanical energy into electrical energy. Specifically, the power generation component includes a stator part 4 and a rotor part 5. The stator part 4 may specifically include a permanent magnet 43, or an excitation coil capable of generating a magnetic field, etc. The rotor part 5 may specifically include a rotor coil 51. When the driving device drives the inner barrel 2 to rotate relative to the bearing component, the rotor part 5 fixed to the inner barrel 2 rotates relative to the stator part 4 fixed to the bearing component, so that the rotor coil 51 cuts the magnetic induction lines of the permanent magnet 43 (or the excitation coil), thereby generating electrical energy, and then introducing the electrical energy to the electrical components arranged in the inner barrel 2 through conductive connection methods such as wires 6 to achieve the purpose of supplying power to the electrical components.

[0043] Since the rotor part 5 is fixed to the inner barrel 2, the wire 6 connected between the rotor part 5 and the inner barrel 2 also remains relatively fixed to the inner barrel 2, thus making the wiring simpler, so as to achieve the purpose of supplying power to the inside of the rotating inner barrel 2 and solve the problem of difficult power supply to the inside of the inner barrel 2 caused by the rotation of the inner barrel 2.

[0044] In addition, by arranging the power generation component outside the inner barrel 2, compared with arranging the power generation component in the inner cavity of the inner barrel 2, on the one hand, the arrangement of the power generation component does not affect the original accommodation space of the inner barrel 2 and the simplicity and aesthetics of the original inner cavity of the inner barrel 2. On the other hand, since the power generation component located outside the inner barrel 2 will not contact the wet clothes located inside the inner barrel 2, there is no need to perform waterproof sealing treatment to avoid contact between the power generation component and the wet clothes, making the structure simpler and the cost lower.

[0045] It should be noted that the electrical component may specifically be a humidity sensor 23 to directly contact the clothes in the barrel with the humidity sensor 23 to detect the humidity of the clothes in the barrel and improve the sensitivity and accuracy of detection. The electrical component may also specifically be a light-emitting lamp to illuminate the inner barrel 2 with the light-emitting lamp, facilitating the user to directly know the processing situation of the clothes in the barrel and being beneficial to improving the user experience effect. Of course, the electrical component may also be other electrical components set according to needs, which are not specifically limited herein.

[0046] In some embodiments, referring to Figure 1 and Figure 2 as shown, the bearing component includes a bearing plate 1, and the stator part 4 is fixed on the bearing plate 1; the driving device includes a power source and a transmission shaft 3 connected to the power source; the transmission shaft 3 passes through the inner barrel 2 and the rotor part 5, and is fixedly connected to the inner barrel 2 and the rotor part 5, and the transmission shaft 3 passes through the bearing plate 1 and is rotatably connected to the bearing plate 1.

[0047] Exemplarily, taking a dryer as an example, the bearing member can be the outer shell of the dryer, and the inner tub 2 of the dryer is rotatably installed inside the outer shell of the dryer; the bearing plate 1 can specifically be the rear plate of the outer shell, and the inner tub 2 of the dryer is connected to the rear plate of the outer shell through a transmission shaft 3, so as to bear the inner tub 2 through the rear plate, such that the inner tub 2 rotates relative to the rear plate with the transmission shaft 3 as the axis under the drive of a power source; the power source can specifically be a driving motor, and the driving motor can be installed on the outer shell.

[0048] Furthermore, the stator portion 4 is fixed on the bearing plate 1; the transmission shaft 3 passes through the inner tub 2 and the rotor portion 5, and is fixedly connected to the inner tub 2 and the rotor portion 5, and the transmission shaft 3 passes through the bearing plate 1 and is rotatably connected to the bearing plate 1. That is to say, the inner tub 2, the rotor portion 5 and the bearing plate 1 are connected through the transmission shaft 3, wherein the inner tub 2 and the rotor portion 5 are fixedly connected to the transmission shaft 3, and the bearing plate 1 is rotatably connected to the transmission shaft 3. With such a setting, when the power source drives the transmission shaft 3 to rotate, the transmission shaft 3 can drive the inner tub 2 and the rotor portion 5 to rotate, while the bearing plate 1 and the stator portion 4 fixed to the bearing plate 1 remain stationary, thereby realizing the rotation of the rotor portion 5 relative to the stator portion 4 to generate electric energy, with a simple structure and easy implementation.

[0049] In some embodiments, referring to Figure 1 and Figure 2 as shown, the transmission shaft 3 is fixedly connected to the inner tub 2 and the rotor portion 5 by an interference fit manner, and the transmission shaft 3 is rotatably connected to the bearing plate 1 through a bearing.

[0050] Exemplarily, the transmission shaft 3 includes a first shaft segment, a second shaft segment and a third shaft segment connected in sequence, the diameter of the first shaft segment is greater than the diameter of the second shaft segment, the diameter of the second shaft segment is greater than the diameter of the third shaft segment, a first limiting step is formed at the connection between the first shaft segment and the second shaft segment, and a second limiting step is formed at the connection between the second shaft segment and the third shaft segment; correspondingly, a first mounting shaft hole for the transmission shaft 3 to pass through is formed on the inner tub 2, the inner diameter of the first mounting shaft hole is less than the diameter of the second shaft segment and greater than the diameter of the third shaft segment, the inner diameter of the second mounting shaft hole is less than the diameter of the third shaft segment, and the inner diameter of the third mounting shaft hole is greater than the diameter of the third shaft segment.

[0051] During specific assembly, the transmission shaft 3 sequentially passes through the first mounting shaft hole, the second mounting shaft hole and the third mounting shaft hole, the second shaft segment is in interference fit with the first mounting shaft hole to realize the fixation of the transmission shaft 3 and the inner tub 2, the third shaft segment is in interference fit with the second mounting shaft hole to realize the fixation of the transmission shaft 3 and the rotor portion 5, and a bearing is installed between the third shaft segment and the third mounting shaft hole to realize that the transmission shaft 3 can rotate relative to the bearing plate 1.

[0052] With such a setting, the installation structure of the stator portion 4 and the rotor portion 5 is relatively simplified, the structural modification of the original clothing treatment equipment is small, the cost is low, and the feasibility is good.

[0053] It should be noted that the rotor part 5 is not limited to being fixed on the transmission shaft 3 by interference fit. It is also feasible to directly fix the rotor part 5 on the inner barrel 2, for example, by fastening connection, snap connection, adhesive connection, etc., to fix the rotor part 5 on the inner barrel 2.

[0054] In some embodiments, referring to Figure 1 and Figure 2 as shown, the stator part 4 is arranged on the side of the bearing plate 1 facing the inner barrel 2 and is adjacent to the rotor part 5. With this arrangement, on the one hand, the installation positions of the stator part 4 and the rotor part 5 are relatively close to ensure the reliability of generating electric energy by the rotation of the rotor part 5 relative to the stator part 4; on the other hand, the installation positions of the stator part 4 and the rotor part 5 are relatively compact, which is convenient for installation.

[0055] Specifically, referring to Figure 3 as shown, the stator part 4 includes a stator housing 41 and permanent magnets 43 arranged in the stator housing 41; the rotor part 5 includes a rotor coil 51. With this arrangement, when the driving device drives the inner barrel 2 to rotate, the rotor part 5 rotates relative to the stator part 4 together with the inner barrel 2, so that the rotor coil 51 rotates relative to the permanent magnets 43, and then cuts the magnetic induction lines generated by the permanent magnets 43 to generate electric energy.

[0056] In specific implementation, the stator housing 41 can be a cylindrical housing with one side open. The number of permanent magnets 43 is multiple, and the multiple permanent magnets 43 are sequentially arranged in the stator housing 41 along the circumferential direction of the stator housing 41; the rotor coil 51 can include a coil support and multiple sets of coil windings wound around the coil support, and the multiple coil windings are sequentially arranged around the central axis of the coil support along the circumferential direction. Further, during specific assembly, the rotor coil 51 can be installed in the inner region of the stator housing 41. More specifically, the rotor coil 51 can be installed in the inner region surrounded by the multiple permanent magnets 43.

[0057] It should be noted that the number of the permanent magnets 43 and the coil windings of the rotor coil 51 are not limited herein and can be reasonably set according to actual situations.

[0058] Further, referring to Figure 3 as shown, a stator fixing seat 42 is arranged on the stator housing 41, and the stator fixing seat 42 is fixedly connected to the bearing plate 1 through fasteners. With this arrangement, the fixation of the stator part 4 on the bearing plate 1 is realized, and the structure is simple and the installation is convenient.

[0059] Exemplarily, a plurality of stator fixing seats 42 are circumferentially and spacedly arranged on the outer peripheral edge of the stator housing 41. A fastener mounting hole is formed in each stator fixing seat 42, and a fastener fixing hole corresponding to the fastener mounting hole one by one is formed in the carrier plate 1. The stator housing 41 is fixedly connected to the carrier plate 1 through a fastener passing through the fastener mounting hole and the fastener fixing hole.

[0060] Of course, the fixing structure of the stator housing 41 and the carrier plate 1 is not limited to the above description, and it can also be a connection structure such as bonding, welding, snap connection, etc.

[0061] Furthermore, a wiring terminal 52 is provided on the rotor coil 51. The wiring terminal 52 is electrically connected to the electrical component through a wire 6, so as to realize the transmission of the electric energy generated by the rotor coil 51 to the electrical component located in the inner cavity of the inner barrel 2 through the wire 6, and realize power supply to the electrical component. Specifically, the wiring terminal 52 can be arranged on the coil bracket of the rotor coil 51.

[0062] It should be noted that the stator part 4 is not limited to including the stator housing 41 and the permanent magnet 43 arranged in the stator housing 41. In some other embodiments, the stator part 4 includes the stator housing 41 and an exciting coil arranged in the stator housing 41. The rotor part 5 includes a rotor coil 51. The rotor coil 51 is located in the magnetic field generated by the exciting coil to generate electric energy by cutting the magnetic induction lines generated by the exciting coil when the rotor coil 51 rotates.

[0063] In some embodiments, referring to Figure 1 、 Figure 2 and Figure 4 as shown, lifting ribs 21 are arranged on the inner wall of the inner barrel 2, and the electrical components are fixed on the lifting ribs 21. On the one hand, the lifting ribs 21 protrude from the inner wall surface of the inner barrel 2, which is more conducive to contacting the clothes in the inner barrel 2. By arranging the electrical components on the lifting ribs 21, the electrical components (such as the humidity sensor 23) can better contact the clothes in the inner barrel 2; on the other hand, the lifting ribs 21 protrude from the inner wall surface of the inner barrel 2, which is more conducive to the installation and fixation of the electrical components in the inner cavity of the inner barrel 2.

[0064] Specifically, the electrical components can be fixed on the lifting ribs 21 by means of snap connection, fastener fixation, bonding, etc., which are not specifically limited herein.

[0065] Furthermore, referring to Figure 4 as shown, a hollow cavity is formed in the lifting rib 21, and a power conversion and energy storage unit 22 is arranged in the hollow cavity. The power conversion and energy storage unit 22 is electrically connected to the rotor part 5 through a wire 6, and the power conversion and energy storage unit 22 is electrically connected to the electrical component.

[0066] By providing a power conversion and energy storage unit 22, the electrical energy generated by the rotation of the rotor part 5 relative to the stator part 4 is converted into a voltage suitable for electrical components by using the power conversion and energy storage unit 22, so as to supply power to the electrical components. In addition, the power conversion and energy storage unit 22 can also be used to store the electrical energy generated by the power generation assembly. Thus, when the inner barrel 2 is not operating, the power conversion and energy storage unit 22 can supply power to the electrical components. Of course, if continuous power supply is not required, the energy storage unit can be cancelled.

[0067] It should be noted that the electrical components are not limited to being installed on the lifting ribs 21 inside the inner barrel 2, and can also be installed at other positions inside the inner barrel 2 as required.

[0068] In some embodiments, referring to Figure 2 As shown, a first mounting hole is formed in the inner barrel 2, and a first sealing ring 24 is provided at the first mounting hole. The wire 6 passes through the first sealing ring 24 and extends into the inner cavity of the inner barrel 2. This is arranged to achieve waterproof sealing at the wire passing position of the inner barrel 2.

[0069] Referring to Figure 4 As shown, a second mounting hole is formed in the lifting rib 21, and a second sealing ring 25 is provided at the second mounting hole. The wire 6 passes through the second sealing ring 25 and extends into the hollow cavity of the lifting rib 21. This is arranged to achieve waterproof sealing at the wire passing position of the lifting rib 21.

[0070] It should be noted that although the embodiments of the present utility model are described by taking a dryer as an example, the clothing treatment device of the embodiments of the present utility model can obviously also be other devices, such as a drum washing machine, etc. Correspondingly, the bearing component for carrying the inner barrel can be an outer barrel or a housing, with a similar structure and the same principle, which will not be elaborated herein.

[0071] It should be noted that in this text, relative terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
