Detailed ways

The preferred embodiments of the present invention will be described below with reference to the drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific applications. For example, although the description takes the light-emitting lamp as the lighting lamp as an example, the light-emitting lamp of the present invention can obviously also be other functional lamps such as ultraviolet germicidal lamps or mosquito killers to meet other requirements.

1 and 2, in a possible implementation manner, the washing machine includes a pulsator 4 and a rotating tub 5. The pulsator 4 is arranged at the bottom of the rotating tub 5 and passes through a clutch with the rotating tub 5 (not shown in the figure) The washing machine also includes a magnet supply module 1, a magnet induction power generation module 2 and a light-emitting lamp 3. The magnet induction power generation module 2 is fixed on one of the rotating tub 5 or the pulsator 4, and the magnet supply module 1 corresponds to the magnet induction power generation module 2. The position is fixed on the other of the rotating barrel 5 or the pulsator 4; 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 is fixed on the rotating barrel 5 or On the pulsator 4; the magnet supply module 1 generates a magnetic field. When the magnet induction power generation module 2 reciprocates on a path close to or away from the magnet supply module 1, the magnet induction power generation module 2 can generate electric energy inside, thereby powering the light-emitting lamp 3.

Through the expression of the above structure, those skilled in the art can know that the above technical solution can drive the magnet induction power generation module 2 to reciprocate on a path close to or away from the magnet supply module 1 through the relative rotation of the pulsator 4 and the rotating barrel 5. Since the induction power generation module 2 is close to or far away from the magnet supply module 1, a changing magnetic field is generated inside of the induction power generation module 2 to realize the power supply of the light-emitting lamp 3. However, among the various working states of the washing machine, not all working states have the relative rotation of the rotating tub 5 and the pulsator 4, and even with relative rotation, it cannot be guaranteed that the relative rotation speed difference can meet the demand. For example, the pulsator When the washing machine is in the washing state, the relative rotation speed of the pulsator 4 and the rotating tub 5 is limited. In this case, the power generation is difficult to maintain the lighting of the luminous lamp. Therefore, the art still needs a washing machine control method to solve this problem. The main flow chart of the control method of the present invention is shown in Figure 3, including:

S100. Control the clutch to be in a closed state where the rotating barrel and the pulsator are fixedly connected;

S200. Control the rotating barrel to increase the speed to the set speed;

S300. Control the clutch to be in an open state to separate the rotating barrel and the pulsator;

S400: Control the rotating barrel or pulsator to slow down or stop.

In the case of insufficient power generation and need to recharge, the washing machine can be controlled to enter the above-mentioned control method. First, close the clutch to make the rotating tub 5 and the pulsator 4 reach a higher set speed, then turn on the clutch and control the rotating tub 5 or One of the pulsator 4 slows down or stops, and the other still has a higher speed according to inertia. At this time, the difference in speed between the rotating barrel 5 and the pulsator 4 can drive the magnet supply module 1 and the magnet induction power generation model. 2 Produce a high relative displacement speed, and then generate sufficient electric energy to supply power to the light-emitting lamp 3.

2 and 4, a specific implementation of the control method of the present invention will be described in detail. As shown in FIG. 4, the control method of the present invention includes:

S110. Determine the working state of the washing machine;

S120. When the washing machine is in the washing, rinsing or dehydration working state, the control clutch is in a closed state in which the rotating tub and the pulsator are fixedly connected;

S200. Control the rotating barrel to increase the speed to the set speed;

S400, control the rotating barrel or pulsator to slow down or stop;

S500. Obtain the number of times the rotating barrel or pulsator slows down or stops;

S600: Selectively control the washing machine to return to the washing, rinsing or dehydration working state before entering the control method according to the number of times the rotating tub or the pulsator is decelerated or stopped;

S610. When the number of times the rotating tub or the pulsator slows down or stops ≥ the set number of times, control the washing machine to return to the washing, rinsing or dehydration working state before entering the control method;

S620. When the number of times the rotating tub or the pulsator slows down or stops <the set number of times, control the washing machine to return to the step of "control the rotating tub to rotate up to the set speed".

The detailed flow chart of the present invention is compared with the main flow chart. Steps S110 and S120 increase the judgment of the working state of the washing machine. Since the washing machine is divided into multiple working states, not every working state is applicable to the control method of the present invention, for example, If the washing machine is in the working state of drying clothes, since the clothes are not washed in water, the relative movement of the rotating tub 5 and the pulsator 4 at this time may cause the clothes to be drawn into the gap, which is not expected by those skilled in the art. It can be seen that the control method of the present invention is not applied as much as possible in this working state. By judging the working state of the washing machine, the present invention can be implemented more reliably without causing damage to the clothes or the washing machine.

In addition, steps S500-S620 are added to determine whether the lighting power or lighting time is satisfied by controlling the number of times the rotating barrel 5 or pulsator 4 slows down or stops. When the rotating barrel 5 or pulsator 4 slows down or stops When the number of times ≥ the set number of times, the lighting power has been met at this time, and the normal washing machine can be operated. Therefore, the washing machine is controlled to return to the washing, rinsing or dehydrating state before entering the control method; when the rotating barrel 5 or the pulsator 4 slows down or When the number of stops <the set number of times, the electricity consumption for lighting is still insufficient or the lighting time is still insufficient at this time, and electricity needs to be continued to be generated. Therefore, the washing machine is controlled to return to step S200 "Control the rotation of the rotating tub to increase to the set speed" and continue to generate Electrical energy.

So far, the main steps of the control method of the washing machine of the present invention have been introduced. However, since the structure of the washing machine is only exemplarily described in the above technical solution, in order to make the reader more clearly understand the magnet supply module 1, the magnet of the present invention For specific implementations of the structure of the induction power generation module 2, etc., the specific structure of the washing machine will be described in detail below, so as to make the structure of the washing machine of the present invention more fully demonstrated.

Specifically, in a possible implementation, as shown in FIG. 2, a magnet supply module 1 is fixedly arranged at the bottom of the rotating tub 5 of the pulsator washing machine to generate magnets, which can be permanent magnets, or of course. It is an electromagnet or other device or equipment that can generate a magnetic field. A magnet induction power generation module 2 is fixed at the position of the pulsator 4 corresponding to the magnet supply module 1 (the corresponding position here is that the two can be close to or far away from each other during the rotation), and the magnet induction power generation module 2 includes a first A housing 21, a second housing 22, a coil 23 and a magnetizer 24, and the first housing 21 and the second housing 22 are all sealed housings. The first housing 21 is fixed to the pulsator 4, the second housing 22 is fixed to the inner side of the first housing 21, the coil 23 is wound on the outer side of the second housing 22, and the conductor 24 is fixed to the inner side of the coil 23 and is connected to the magnet The supply 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 rotating barrel 5 and the pulsator 4 have relative motion, each time the pulsator 4 rotates relative to the rotating barrel 5, the magnet induction power generation module 2 will approach the primary permanent magnet and move away from the primary permanent magnet. The magnetic field conductor 24 will increase its own magnetic field when it is close to the permanent magnet, and when it is far away from the permanent magnet, it will reduce its own magnetic field. The magnetic field conductor 24 will complete a change in the size of the magnetic field. Relative to the movement of the coil 23, this realizes that the coil 23 cuts the magnetic induction line, thereby generating an electric current to make the light-emitting lamp 3 light up.

In summary, the present invention provides a method for controlling a washing machine having a magnet supply module 1 and a magnet induction power generation module 2, which can improve the power generation capacity of the washing machine and further illuminate the interior of the washing machine, thereby solving the problem of the washing machine in the prior art. The problem of internal lighting is difficult to achieve. In addition, the control method of the present invention is selectively used for different working conditions to further ensure the safety of the washing machine during the working process. In addition, the present invention also provides steps S500-S620 for indirectly judging whether the power generation meets the set demand by judging the number of cycles, so that the washing machine can achieve sufficient lighting time or obtain sufficient lighting power.

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, 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. Moreover, 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 rotating barrel 5, but five magnet induction power generation modules 2 are arranged on the pulsator 4. If it rotates, it can obviously still generate electricity and turn on the light-emitting lamp 3, which does not deviate from the principle of the present invention, and therefore will 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 control method of the washing machine of the present invention can obviously also be applied to other washing machines. For example, a drum washing machine, etc., when the washing machine is a pulsator washing machine, the rotating tub 5 is correspondingly an inner tub, and when the washing machine is a drum washing machine, the rotating tub 5 is correspondingly an inner tub.

Those skilled in the art can understand that the above washing machine also includes some other well-known structures, such as a processor, a controller, a memory, etc., where the memory includes, but is not limited to, random access memory, flash memory, read-only memory, programmable read-only memory, and volatile Non-volatile memory, non-volatile memory, serial memory, parallel memory or registers, etc. Processors include but are not limited to CPLD/FPGA, DSP, ARM processor, MIPS processor, etc. In order to unnecessarily obscure the embodiments of the present disclosure, these well-known structures are not shown in the drawings.

Although the various steps are described in the above-mentioned order in the above-mentioned embodiment, those skilled in the art can understand that in order to achieve the effect of this embodiment, different steps need not be executed in this order, and they can be performed simultaneously ( Parallel) execution or in reverse order, these simple changes are all within the protection scope of the present invention.

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.
