[0002] In existing laundry treatment devices such as washing machines or dryers, in order to detect parameters such as temperature, humidity, and water level in the inner tub, corresponding detection sensors often need to be provided inside the inner tub, and these detection sensors are powered by a power supply module located outside the inner tub, which restricts the types, installation positions, and power supply methods of the respective detection sensors to a certain extent. At the same time, it also makes the internal wiring structure of the laundry treatment device complex and poses certain potential safety hazards. Summary of the Utility Model

[0025] In order to be able to more clearly understand the above objects, features and advantages of the present application, the following will further describe the solution of the present application. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0026] In the following description, numerous specific details are set forth to provide a thorough understanding of the present application. However, the present application may 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 application, rather than all of the embodiments.

[0027] In existing laundry treatment devices such as washing machines or dryers, in order to detect parameters such as water level, temperature, and humidity, corresponding detection sensors are usually installed in the laundry treatment device. At the same time, in order to facilitate the operator to observe the operation situation inside the inner tub, devices such as barrel lights are installed inside the inner tub. Since the power supply device for supplying power to the detection sensors and barrel lights is arranged outside the inner tub, the position, model, and power supply method of the detection sensors are relatively restricted. At the same time, it will also lead to a complex internal wiring structure of the laundry treatment device, resulting in certain potential safety hazards.

[0028] Taking a dryer as an example, due to the problem that the existing dryer inner tub cannot achieve power supply, the sensor for detecting humidity in the inner tub usually needs to be arranged on the filter screen assembly, resulting in the sensor not being able to directly contact the clothes, reducing the accuracy of the detection result.

[0029] As Figure 1 shown, to solve the above technical problems, an embodiment of the present application provides a laundry treatment device, including a rear panel 1, an inner tub 2, a generator 7, a second transmission wheel 6, an electrical component, and a driving device. Among them, a first transmission wheel 5 is provided on the rear panel 1, and the first transmission wheel 5 is fixedly connected to the rear panel 1. The inner tub 2 is rotatably installed on the rear panel 1. A transmission shaft 4 is provided on the rear panel 1, and the transmission shaft 4 rotatably passes through the rear panel 1. The inner tub 2 is fixedly connected to the transmission shaft 4. The driving device is connected to the transmission shaft 4 to drive the transmission shaft 4 to rotate, and then drive the inner tub 2 to rotate. The generator 7 is arranged on the inner tub 2 and rotates together with the inner tub 2 when the inner tub 2 rotates. The second transmission wheel 6 is connected to the rotor of the generator 7 and meshes with the first transmission wheel 5. When the inner tub 2 rotates, it drives the generator 7 to rotate together. Since the second transmission wheel 6 has a meshing relationship with the first transmission wheel 5, the second transmission wheel 6 will drive the rotor of the generator 7 to rotate self - sufficiently, thereby realizing the power generation of the generator 7. The electrical component is arranged inside the inner tub 2 and is electrically connected to the generator 7. The electricity generated by the generator 7 is supplied to the electrical component inside the inner tub 2 for use. Since the generator 7 is located on the inner tub 2, the distance between the generator 7 and the electrical component is shortened, the wiring structure is simplified, the potential safety hazard is reduced. At the same time, the installation position of the power generation element is more flexible and can be directly arranged on the inner tub 2, directly contacting the clothes or water inside the inner tub 2, and the detection effect is more accurate.

[0030] Exemplarily, taking a dryer as an example, due to the problem that the inner tub 2 cannot be directly powered, a humidity sensor is usually arranged on the filter screen assembly in a traditional dryer. After adopting the solution of the embodiment of the present application, a generator 7 is arranged on the inner tub 2 of the dryer. By the rotation of the inner tub 2, the rotation of the rotor of the generator 7 is driven, and then power generation is realized. The power generated by the generator 7 is supplied to the humidity sensor for use. The humidity sensor can be directly arranged on the inner tub 2 and is in direct contact with the clothes in the dryer during operation, improving the detection accuracy.

[0031] The number of the generators 7 can be one or more. When the number of the generators 7 is multiple, the generators 7 are arranged circumferentially around the inner tub 2. Multiple second drive wheels 6 correspond to the multiple generators 7. The multiple second drive wheels 6 are arranged at intervals circumferentially around the first drive wheel 5 and are all engaged with the first drive wheel 5. When the inner tub 2 rotates, power generation of multiple generators 7 can be realized simultaneously.

[0032] Furthermore, in some embodiments of the present application, lifting ribs 8 are provided on the inner wall of the inner tub 2. A receiving cavity is provided inside the lifting ribs 8. The generator 7 is arranged in the receiving cavity. The so-called lifting ribs 8 are simply long strip-shaped protrusions on the inner tub 2 of a washing machine or a dryer. Its main function is to increase the friction with the clothes when the clothes tumble, further improving the cleaning effect. By arranging the generator 7 in the receiving cavity, the generator 7 is installed by using the inherent structure of the washing machine and the dryer itself. The structural improvement of the washing machine and the dryer is small, reducing the cost of re-opening the mold. Moreover, the generator 7 is hidden in the receiving cavity, avoiding exposure, having a certain protective effect on the generator 7, and at the same time not affecting the capacity of the inner tub 2.

[0033] Furthermore, in some embodiments of the present application, the generator 7 is located at one end of the inner tub 2 close to the rear plate 1, so that the overall structure of the laundry treatment device is relatively compact, improving the stability of the transmission structure.

[0034] Furthermore, in some embodiments of the present application, through holes are formed in the inner tub 2. The second drive wheel 6 is located outside the inner tub 2 and is fixedly connected to the rotor of the generator 7 through a connecting rod. The connecting rod is rotatably arranged in the through hole. The through hole communicates the receiving cavity and the outside of the inner tub 2. One end of the connecting rod is connected to the second drive wheel 6, and the other end is connected to the rotor of the generator 7. When the inner tub 2 rotates, the second drive wheel 6 is engaged with the first drive wheel 5 to realize the rotation of the second drive wheel 6, and then drive the rotation of the connecting rod and the rotor of the generator 7, thereby realizing the power generation of the generator 7.

[0035] Furthermore, bearings 3 are arranged in the through holes. The outer ring of the bearing 3 is fixedly connected to the inner wall of the through hole, and the inner ring of the bearing 3 is sleeved on the connecting rod.

[0036] Further, in some embodiments of the present application, the first transmission wheel 5 is coaxially arranged with the inner barrel 2, and the axis of the second transmission wheel 6 is parallel to the axis of the first transmission wheel 5. So that during the rotation of the inner barrel 2, the second transmission wheel 6 can always mesh with the first transmission wheel 5.

[0037] Further, in some embodiments of the present application, the diameter of the second transmission wheel 6 is smaller than that of the first transmission wheel 5. During the rotation of the inner barrel 2, when the inner barrel 2 rotates one circle, the second transmission wheel 6 rotates multiple circles, improving the power generation efficiency of the generator 7.

[0038] Further, the first transmission wheel 5 and the second transmission wheel 6 can be gears or friction wheels. Exemplarily, in some embodiments of the present application, both the first transmission wheel 5 and the second transmission wheel 6 are friction wheels. Therefore, when the first transmission wheel 5 and the second transmission wheel 6 mesh and drive each other, the frictional force between the two can drive the relative rotation between the second transmission wheel 6 and the first transmission wheel 5, thereby realizing the power generation of the generator 7.

[0039] Further, in some embodiments of the present application, the laundry treatment device further includes an energy storage unit. The generator 7 is electrically connected to the energy storage unit. The electric energy generated by the generator 7 can be directly supplied to the electrical components, or can be first stored in the energy storage unit and then supplied to the electrical components through the energy storage unit. When the inner barrel 2 does not rotate, the electrical components can be powered by the energy storage unit.

[0040] The energy storage unit can be a lithium battery, a nickel-chromium battery or a nickel-metal hydride battery, etc. The energy storage unit and the electrical components can be connected by wires to realize power supply to the electrical components.

[0041] The laundry treatment device further includes a power detection unit for the energy storage unit's power. When the power detection unit detects that the voltage of the energy storage unit is lower than the preset voltage, it reminds that the power is insufficient and feeds back the information of insufficient power to the control unit of the laundry treatment device. The control unit takes corresponding solutions according to the received signal of insufficient power and in combination with the current operating state of the laundry treatment device.

[0042] When the laundry treatment device is a dryer, before entering the drying program or after the drying program ends, the power detection unit detects the power of the energy storage unit.

[0043] If before entering the drying program, the power detection unit detects that the power of the energy storage unit is insufficient, the inner barrel 2 can be controlled to first execute the corresponding program to charge the energy storage unit, and then start to introduce high-temperature steam, or charge the energy storage unit while introducing high-temperature steam or ultraviolet irradiation.

[0044] After the drying program ends, if the power detection unit detects that the power of the energy storage unit is insufficient, the inner tub 2 can be controlled to execute the corresponding charging program to charge the energy storage unit, and then the dryer is controlled to cut off the power, so as to ensure that the energy storage unit can provide sufficient power for the barrel lamp or the detection sensor during the next drying.

[0045] Furthermore, in some embodiments of the present application, a transformer is also connected between the energy storage unit and the generator to adjust the voltage generated by the generator and store it in the energy storage unit to continuously supply power to the electrical components.

[0046] Furthermore, in some embodiments of the present application, both the energy storage unit and the transformer are provided in the accommodating cavity, reducing the occupation of the inner tub volume. At the same time, arranging the energy storage unit, the transformer and the generator in the accommodating cavity also shortens the length of the electrical connection as much as possible and simplifies the electrical connection structure.

[0047] Furthermore, in some embodiments of the present application, the electrical component includes a detection sensor, and the detection sensor is arranged on the inner wall of the inner tub. Specifically, the detection sensor can be a humidity sensor, a temperature sensor or a water level sensor, etc. Since a generator is arranged on the inner tub to supply power to the detection sensor, the detection sensor can be arranged on the inner wall of the inner tub. Specifically, it can be arranged on the surface of the lifting rib and be in direct contact with the clothes in the inner tub to improve the detection accuracy.

[0048] In summary, for the laundry treatment device according to the embodiments of the present application, a generator is arranged in the lifting rib of the inner tub. When the inner tub rotates, the second transmission wheel connected to the generator rotor meshes with the first transmission wheel fixed on the rear plate externally, so that the generator rotor rotates at a certain speed, thereby generating voltage, and the voltage is supplied to the electrical components inside the lifting rib. By using the generator method, the mechanical energy of the rotation of the inner tub is converted into electrical energy, and then the electrical energy is introduced into the inner tub. Further, the detection sensor can be directly arranged on the surface of the lifting rib, so that the clothes are in direct contact with the detection sensor, improving the sensitivity.
