For those skilled in the art, the specific meaning of the above-mentioned terms in the present invention can be understood according to specific circumstances.

1 to 3, in a possible implementation manner, the laundry treatment equipment includes a rotating part 4 and a stationary part 5. The rotating part 4 is self-rotatably arranged in the stationary part 5. In a pulsator washing machine, the rotating part 4 It is a pulsator, and correspondingly, the stationary part 5 is an inner barrel. The clothing treatment equipment also includes a magnet supply module 1, a magnet induction power generation module 2, a mounting frame 6, and a light-emitting lamp 3. The magnet induction power generation module 2 is fixed on the rotating part 4, and the magnet supply module 1 corresponds to the position of the magnet induction power generation module 2. The mounting frame 6 is fixed on the stationary part 5; the light-emitting lamp 3 is electrically connected to the magnet induction power generation module 2 and fixed on the magnet induction power generation module 2 or together with the magnet induction power generation module 2 on the rotating part 4 or the stationary part 5; The magnet supply module 1 generates a magnetic field. When the rotating part 4 rotates relative to the stationary part 5, the magnet induction power generation module 2 reciprocates on a path close to or away from the magnet supply module 1, and the magnetic poles supplied by the adjacent magnet supply modules 1 are opposite , For example, an adjacent N pole is facing upwards, an S pole is facing upwards, and the cycle is in turn. More preferably, the distribution method is uniform distribution.

Specifically, in a possible implementation, as shown in FIG. 2, a magnet supply module 1 is fixedly arranged at the bottom of the inner tub of the pulsator washing machine to generate magnets, which can be permanent magnets, or of course electromagnetics. Iron or other devices or equipment that can generate a magnetic field, etc. A magnet induction power generation module 2 is fixed at the position of the pulsator corresponding to the magnet supply module 1. The magnet induction power generation module 2 includes a first housing 21, a second housing 22, a coil 23 and a magnetic conductor 24, and the first housing The body 21 and the second housing 22 are both sealed housings. The first housing 21 is fixed on the pulsator, the second housing 22 is fixed on the inside of the first housing 21, the coil 23 is wound on the outside of the second housing 22, and the magnetic conductor 24 is fixed on the inside of the coil 23 and supplied with the magnet The module 1 is correspondingly arranged, and the light-emitting lamp 3 is electrically connected to the coil 23. Wherein, the magnetic conductor 24 may be an iron core, of course, it may also be another member or device, as long as it can produce an object that changes its magnetic field as the permanent magnet approaches or moves away.

The overall working process is: when the pulsator starts to rotate, the magnet induction power generation module 2 will also rotate, and the permanent magnet is fixed on the inner barrel and cannot move. At this time, the magnet induction power generation module 2 is rotated every time the pulsator rotates. It will be close to the permanent magnet once and far away from the permanent magnet. Correspondingly, when the magnetic conductor 24 is close to the permanent magnet, its own magnetic field will increase, and when it is far away from the permanent magnet, its own magnetic field will decrease. , The magnetic conductor 24 completes a change in the size of the magnetic field, and the continuous change of the magnetic field will cause the magnetic line of induction to move relative to the coil 23, which realizes that the coil 23 cuts the magnetic line of induction, thereby generating a current and causing the light-emitting lamp 3 to light up.

The advantages of the above-mentioned setting method are that the setting is simple and easy to implement, and no separate circuit is required to realize the lighting inside the pulsator washing machine, thereby solving the problem of external power wiring. The design of the permanent magnet and the permeable magnet 24 cleverly solves the conduction between the magnetic fields, making the overall structure simpler and having better feasibility. The design of the adjacent magnet supply modules 1 with opposite magnetic poles makes the magnetic change inside the magnet induction power generation module 2 more severe, so that more electric energy can be generated. The evenly distributed design can make the magnetic pole change evenly, which is more conducive to controlling the current situation and avoiding the damage of the light-emitting lamp 3. The design of the mounting frame 6 enables the magnet supply module 1 to be pre-installed on the mounting frame 6 and then integrally installed on the inner barrel 5. First of all, there is no need to make additional changes to the inner barrel to adapt to the installation structure of multiple magnet supply modules 1. The mounting frame 6 can be fixed as a whole, which can also minimize the structural changes of the inner barrel 5, so that there is no need to make major changes to the production line, which is more conducive to the actual production. In addition, multiple magnet supply modules can be installed on the mounting frame 6 as a whole After being assembled into the clothes processing equipment as a whole, the assembly efficiency can also be greatly improved, thereby reducing the overall cost of the clothes processing equipment.

It should be noted that the above-mentioned embodiments are only used to illustrate the principles of the present invention, and are not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above-mentioned structure to facilitate The present invention can be applied to more specific application scenarios.

For example, in an alternative embodiment, the second housing 22 is provided for better structural optimization and waterproofing of the interior, but the first housing 21 itself is a closed cavity, so the second housing 22 is obviously not necessary. It is also a feasible implementation to remove the second housing 22, as long as the coil 23 is directly fixed to the inner wall or bottom of the first housing 21, and the magnetizer 24 is fixed to the bottom of the first housing 21 accordingly. That is, these do not deviate from the principle of the present invention, and therefore all fall within the protection scope of the present invention.

For example, in another alternative embodiment, the light-emitting lamp 3 may be a lighting lamp such as an LED lamp, or an ultraviolet germicidal lamp for sterilization use, or a combination of the two, which can be used for function switching, or Other functional lamps, such as mosquito repellent lamps, etc., do not deviate from the principle of the present invention, and therefore all fall within the protection scope of the present invention.

For example, in another alternative embodiment, the fixing positions of the light-emitting lamp 3 are various. For example, when the specific embodiment is the structure in FIG. 2, the light-emitting lamp 3 can be fixed on the first housing 21 or It can be mounted on wheels. Correspondingly, if the magnet induction power generation module 2 is set on the inner barrel and the magnet supply module 1 is set on the pulsator, the light-emitting lamp 3 can also be set on the inner barrel. Those skilled in the art can choose the appropriate one according to actual needs. These installation positions do not deviate from the principle of the present invention, and therefore all fall within the protection scope of the present invention.

For example, in another alternative embodiment, although only one magnet induction power generation module 2 and one magnet supply module 1 are exemplarily shown in FIG. 2, the number of the two can obviously be set at will. And the two do not have to be arranged in corresponding numbers. For example, three magnet supply modules 1 can be arranged in a circular path at the bottom of the inner barrel, but five magnet induction power generation modules 2 are arranged on the pulsator. As the pulsator rotates, it is obvious It is still possible to generate electricity to light up the light-emitting lamp 3, which does not deviate from the principle of the present invention, and therefore all fall within the protection scope of the present invention.

Finally, it should be noted that although the present invention is described with a pulsator washing machine as an example, the laundry processing equipment of the present invention can obviously also be other equipment. For example, it can also be a drum washing machine, etc. Correspondingly, the rotating part 4 is an inner tube, and the stationary part 5 is an outer tube. The fixing method is similar to that of a pulsator washing machine, and the principle is the same, so it will not be repeated.

It should be noted that the innovative point of the present invention is that the first condition for those skilled in the art to face such problems is to first arrange the line on the outer circumference of the rotating part 4. However, as long as the line is arranged on the rotating part Near the outer circumference of 4, there will be more lines passing through the operation panel to the vicinity of the rotating part 4. Especially for drum washing machines, these wires are usually clipped to the long-term stationary shell or the outside of the rotating part 4 through buckles. On the outer cylinder, this method does not have a major impact in the short term. However, washing machines are electronic products that are used for a long time and have a long service life. The safety and quality of their circuits cannot tolerate the slightest sloppy. Under long-term vibration conditions, the buckles usually fall off, which makes the wires no longer fully fit the outside. , Once the rotating part 4 turns the line into and rotating together, it will cause serious leakage accidents and even fire. In view of this, although the lighting of the rotating part 4 of the drum washing machine is very necessary, for safety reasons, the field Technicians have not yet had a high-safety wiring method to solve this problem. In view of the fact that the light-emitting lamp 3 itself does not need much electric energy to maintain light, and the more wiring outside the rotating part 4, the higher the risk, the inventor creatively proposed the above solution to solve the power supply problem of the light-emitting lamp 3. After many experiments, the inventor found that the electric energy generated by the coil 23 cutting the magnetic induction line is sufficient to maintain the lighting of the light-emitting lamp 3. This method does not require wiring on the outside of the rotating part 4, thereby solving the problem that more wiring is easily involved in rotation. The problem of part 4 saves electric energy and avoids the problem of difficult electrical connection between the rotating drum and the stationary external power source, and provides a new way to solve the problem for the internal lighting of the washing machine. In addition, since no changes have been made to the structure of complex standard parts such as the output shaft of the clothes treatment equipment, only the structure of the pulsator and the inner barrel has been increased. On the whole, the practical feasibility of its application is greatly increased. Because for the production cost, the structural changes are the exterior of certain fixed parts, and only the installation structure, such as threaded holes, etc., is added. This kind of change is small and does not involve the more difficult to change the motor and other equipment, so it can be The practicability is very high, so that the cost of the clothes processing equipment is greatly reduced.

So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
