In the related art, the ultraviolet germicidal lamp is arranged below the upper cover of the washing machine, and ultraviolet rays emitted by the ultraviolet germicidal lamp irradiate the bottom of the inner barrel from top to bottom for a long distance. In order to achieve a good sterilization effect, the power of the ultraviolet sterilization lamp needs to be increased, so that the cost of parts is increased, other parts inside the pulsator washing machine are easy to age, the service life of the pulsator washing machine is shortened, and meanwhile, the power of the ultraviolet sterilization lamp is increased, so that adverse effects on the health of a user are easily caused.

Therefore, the invention also provides a method for supplying power to the ultraviolet germicidal lamp by adopting the coil and the magnetic component which are respectively arranged at the bottoms of the impeller and the inner barrel, thereby avoiding the difficulty of wiring and also achieving the purpose of improving the assembly efficiency. In addition, the invention fully utilizes the relative rotation of the impeller and the inner barrel in the washing process and converts the relative rotation into the induced electricity between the coil and the magnetic component, thereby supplying power to the ultraviolet germicidal lamp under the condition of hardly consuming the power consumption of the impeller washing machine.
The pulsator washing machine comprises a box body, a control panel seat, an outer barrel, an inner barrel, a pulsator and a driving assembly. The control disk seat is arranged at the top of the box body and forms a space for accommodating the inner barrel, the outer barrel, the driving assembly and the like together with the box body. The driving assembly comprises a motor, a clutch assembly and the like, the clutch assembly is assembled at the bottom of the outer barrel, and a motor shaft of the motor is in transmission connection with the clutch.
The outer barrel is connected inside the box body through the damping assembly, an inner barrel is sleeved in the outer barrel, a wave wheel capable of rotating relative to the inner barrel is installed at the bottom of the inner barrel, and the inner barrel and the wave wheel are driven by the driving assembly. The clothes to be washed can be put into the inner barrel through the barrel opening of the inner barrel, washing water can be filled into the inner barrel through the water inlet pipeline, and in the washing process, the impeller and the inner barrel are driven to rotate through the driving assembly, so that the washing water generates vortex, the clothes are driven to turn over up and down in the washing water, and the clothes are cleaned.
In order to realize sterilization, the impeller of the embodiment is provided with an ultraviolet sterilization device and a coil electrically connected with the ultraviolet sterilization device, and the bottom of the inner barrel is provided with a magnetic component; or, the bottom of the inner barrel is provided with a coil and an ultraviolet sterilization device, and the impeller is provided with a magnetic component. When the coil rotates relatively between the impeller and the inner barrel, the coil can cut the magnetic field generated by the magnetic assembly, so that induction current is generated in the coil, and then power is supplied to the ultraviolet sterilization device, so that the ultraviolet sterilization device can emit ultraviolet rays into washing water, and the washing water and clothes can be sterilized.
The structure related to uv sterilization in the present embodiment is described in detail below with reference to the accompanying drawings so that the present solution can be clearly understood, however, it should be understood that the following is only a specific example and should not be considered as a specific limitation to the scope of the present disclosure.
Fig. 1 is a partial structural sectional view of a pulsator washing machine according to an embodiment of the present invention, in which an inner tub and a pulsator are assembled in an assembled state. Fig. 2 is a schematic diagram of a part of the structure in fig. 1. Fig. 3 is a schematic diagram of the exploded structure of fig. 2. In the drawings, the inner tub is denoted by reference numeral 10, and the pulsator is denoted by reference numeral 20.
Referring to fig. 1 to 3, one of the magnetic assembly 30 and the coil 40 is disposed on the inner tub 10, and the other is disposed with the pulsator 20. When the pulsator 20 and the inner tub 10 rotate relatively, the magnetic assembly 30 and the coils 40 are driven to move relatively, so that the coils 40 cut magnetic induction lines of a magnetic field generated by the magnetic assembly 30 to generate induction current. In other words, the pulsator washing machine according to the present embodiment further includes a self-generating unit, the self-generating unit includes a magnetic unit 30 and a coil 40, the ultraviolet sterilization device 50 is electrically connected to the coil 40, and the coil 40 cuts magnetic induction lines in a magnetic field generated by the magnetic unit 30 to generate a current in the coil 40 according to an electromagnetic induction principle as long as the magnetic unit 30 and the coil 40 can perform a relative motion. The coil 40 is electrically connected to the ultraviolet sterilizer 50, and the coil 40 can supply power to the ultraviolet sterilizer 50. Thus, the ultraviolet sterilization device 50 can work normally without using an external power supply, and thus, complicated wiring on the inner tub and/or the pulsator is not required.
The ultraviolet sterilization device 50 of the present embodiment is disposed on the inner tub 10 or the pulsator 20, so that the ultraviolet sterilization device 50 has a small distance from the washing water and the laundry to be washed, high ultraviolet intensity, and a good sterilization effect.
It should be noted that, when only one ultraviolet sterilization device 50 is provided, the ultraviolet rays emitted from the ultraviolet sterilization device 50 can uniformly irradiate the entire inner tub 10 by the relative rotation of the pulsator 20 and the inner tub 10, thereby improving the sterilization effect.
In addition, since the inner tub 10 and the pulsator 20 are generally connected at the axial position with the driving assembly, the coils 40 may be disposed outside the rotational axis of the inner tub 10 and the pulsator 20 in order to avoid the driving assembly and to better cut the magnetic induction lines.
In some implementations, the ultraviolet sterilization device 50 may be disposed on the tub 11 of the inner tub 10, so that the ultraviolet rays emitted from the ultraviolet sterilization device 50 may irradiate the washing water and the laundry from the side.

It should be understood that, when the ultraviolet sterilization device 50 and the coil 40 do not protrude above the top surface of the pulsator 20, the sum of the heights of the coil 40 and the ultraviolet sterilization device 50 is less than the height of the accommodating chamber 22 to avoid collision of the coil 40 or the ultraviolet sterilization device 50 with the inner tub 10.
Of course, the whole of the coil 40 and the ultraviolet sterilization device 50 may also extend out of the top surface of the pulsator 20, and at this time, the sum of the heights of the coil 40 and the ultraviolet sterilization device 50 may be greater than or equal to the height of the accommodating cavity 22, as long as there is a preset safety distance between the whole of the coil 40 and the ultraviolet sterilization device 50 and the bottom 12 of the inner barrel 10.
The protruding portion 21 is provided with a light emitting hole through which ultraviolet rays pass, so that the ultraviolet rays can be emitted into the inner barrel 10 through the light emitting hole.

The quartz glass sheet may be a single sheet or a plurality of superposed sheets, and the specific structure and pattern of the light-transmitting portion 63 are not limited in this embodiment.
Referring to fig. 1, the shielding member 60 defines a closed shielding cavity. In one implementation, the coil 40 and the ultraviolet sterilization device 50 may be enclosed in the protection cavity by injection molding. In another implementation manner, a clamping boss for clamping and fixing the coil 40 and the ultraviolet sterilization device 50 can be arranged inside the protection cavity, and the housing is assembled with the coil 40 and the ultraviolet sterilization device 50 in an assembling manner.
As shown in fig. 2, the outer wall surface of the protection member 60 is provided with a protruding connection boss 64, the connection boss 64 can be clamped with the pulsator 20 or fastened by a bolt, and correspondingly, the bottom surface of the pulsator 20 is provided with a connection portion corresponding to the connection boss 64.
Further, in order to facilitate the disassembly and inspection of the coil 40 and the uv sterilization device 50, the bottom of the protection member 60 is provided with an opening for assembling the coil 40 and the uv sterilization device 50. The opening part can be provided with a protective cover for sealing the opening, and the protective cover can be hinged or clamped with the box body.
Referring to fig. 3, the washing machine further includes a magnetic conductive member 70 penetrating the coil 40 to increase the magnetic flux of the coil 40. The material of the magnetic conductive member 70 may be a permanent magnet, such as iron. When the washing machine works, the magnetic assembly 30 generates a magnetic field, the magnetic conducting member 70 can be magnetized by the magnetic field, the magnetized magnetic conducting member 70 can also generate a magnetic field as a magnet, the magnetic field generated by the magnetic conducting member 70 is superposed with the magnetic field generated by the magnetic assembly 30, the magnetic field intensity of the position of the coil 40 is increased, and the magnetic flux of the coil 40 is increased, so that the power generation efficiency is improved.
As shown in fig. 1, the magnetic conducting member 70 may include a columnar body 71, the coil 40 is provided with a coil hole for the body 71 to pass through, in order to fix the body 71, two ends of the body 71 may be provided with two clamping portions protruding from an outer wall surface of the body 71 along a direction perpendicular to an axis of the inner barrel 10, and the two clamping portions are located at two ends of the coil 40.

With continued reference to fig. 1, the protruding portion 21 of the pulsator 20 is provided with a light emitting hole for emitting ultraviolet rays, and the light transmitting portion 63 is located on the top of the coil 40. Alternatively, the light-transmitting portion 63 may have a preset interval from the light-exit hole, i.e., the light-transmitting portion 63 is located at a lower side of the light-exit hole. Of course, in order to avoid the loss of the ultraviolet rays between the pulsator 20 and the light-transmitting portion 63, the light-transmitting portion 63 is provided in the light-exit hole.

When the protrusions 21 extending in a linear or wavy manner are provided, at least one coil 40 may be provided corresponding to each protrusion 21, and the coils 40 may be provided at intervals along the extending direction of the protrusions 21.
Further, each coil 40 may be provided with one corresponding uv sterilization device 50, and all uv sterilization devices 50 may be turned on simultaneously or some uv sterilization devices 50 may be turned on simultaneously.
Further, the washing machine may further include a rechargeable battery connected to the coil 40 and disposed within the shield 60. When the current generated in the coil 40 is left in addition to the use of the ultraviolet sterilizer 50, the battery can be used to store the electricity, thereby preventing the waste of energy. When the coil 40 or the magnetic assembly 30 fails, the power source can be used as a power element to drive the ultraviolet sterilization device 50 to start.
Referring to fig. 1 and 3, each of the ultraviolet sterilization apparatuses 50 includes a driving plate 51 and at least one ultraviolet lamp 52, the ultraviolet lamp 52 is used for emitting ultraviolet rays, and the driving plate 51 is connected to the coil 40. A controller may be further provided between the driving plate 51 and the coil 40, and the controller controls each uv sterilization device 50 individually to turn on some or all of the uv sterilization devices 50 as needed.
Each uv sterilization device 50 may be correspondingly provided with one or more uv lamps 52, and the uv lamps 52 may be point-shaped lamp beads or strip-shaped lamp strips.
For the second shield part 62, which may include a first section surrounding the driving plate 51 and a second section surrounding outside the ultraviolet lamps, when the sectional area of at least one ultraviolet lamp is smaller than that of the driving plate 51, a second step may be formed between the second section and the first section. It can be understood that the extension height of the second section along the axial direction of the inner barrel 10 may be greater than or equal to the thickness of the protrusion 21, so that when the light-transmitting portion 63 constitutes a portion of the protrusion 21, a portion or the whole of the second section is located in the light-emitting hole.
The light-transmitting part 63 is located on one side of the second section close to the opening of the inner barrel 10, and the part of the second section connected with the light-transmitting part 63 is made of a light-tight material, so that ultraviolet rays are prevented from being emitted from the side of the second section.
The magnetic assembly 30 is used to generate a magnetic field, which may be an excitation coil that generates a magnetic field when energized. In this embodiment, the magnetic assembly 30 may include a plurality of magnets, wherein the number of the magnets may be an even number, each magnet has opposite poles, a line connecting the poles of each magnet is parallel to the axis of the inner barrel 10 and is arranged in an array on a plane perpendicular to the circumferential direction of the inner barrel 10, and the poles of two adjacent magnets are opposite. The magnets may be neodymium iron boron magnets, ferrite magnets, etc. as are well known to those skilled in the art.
A plurality of magnets may be provided on the tub 11 or the tub bottom 12. When the magnet is arranged on the barrel bottom 12, the distance between the coil 40 and the magnet is small, and the magnetic field intensity at the position of the coil 40 is high.
In some implementations, the magnet is disposed outside the tub bottom 12, i.e., between the inner tub 10 and the outer tub, so as to avoid interference collision of the coil 40 with the magnet.
In other implementations, to further reduce the distance between the coil 40 and the magnet to increase the magnetic field intensity at the position of the coil 40, the magnet may be disposed on the top surface of the tub bottom 12 as shown in fig. 1, that is, the magnet may be disposed on the inner surface of the tub bottom 12, and correspondingly, the inner surface of the tub bottom 12 is formed with the grooves 121 downward, and one groove 121 is disposed for each magnet.
Specifically, referring to fig. 1, the recess 121 extends downward, so that at least a portion of the magnet can protrude into the recess 121. Illustratively, the top of the magnet is located in the groove 121 or is flush with the notch of the groove 121, and at this time, the magnet does not collide with the pulsator 20 or the coil 40 to interfere therewith. Of course, the top end of the magnet may protrude from the inner surface of the tub bottom 12, as long as there is a predetermined safety distance between the magnet and the pulsator 20 or the coil 40.
