1 to 6, the laundry treatment equipment of the present invention will be described. 1 is a schematic structural diagram of the laundry treatment device of the present invention as a pulsator washing machine, FIG. 2 is a schematic structural diagram of the laundry treatment device of the present invention as a drum washing machine, FIG. 3 is an exploded view of the structure of the light-emitting component of the present invention, and FIG. 4 It is a three-dimensional view of the light-emitting component of the present invention, FIG. 5 is a front view of the light-emitting component of the present invention, and FIG. 6 is a cross-sectional view at AA in FIG. 5.

As shown in Figures 1 and 3, in order to solve the problems of difficulty in arranging the internal and external power supply of the existing laundry treatment equipment and difficulty in increasing the light source, the laundry treatment equipment of the present invention is explained by taking a pulsator washing machine as an example, including a driving device 1 and a rotating machine. Part 2, the rotating part 2 is the pulsator 21, the output shaft 11 of the driving device 1 is connected to the rotating part 2, the clothing treatment equipment also includes a light-emitting part 3, the light-emitting part 3 includes a waterproof housing 31, a light-emitting lamp 32 and a power supply module 33, waterproof The housing 31 is fixed on the rotating part 2 or the output shaft 11, the light-emitting lamp 32 is electrically connected to the power supply module 33, and the light-emitting lamp 32 and the power supply module 33 are both arranged inside the waterproof housing 31, and the light-emitting lamp 32 is arranged to pass through the waterproof housing The light beam 31 is irradiated to the outside, and the power supply module 33 is configured to generate electric energy based on the rotation of the rotating part 2 or the output shaft 11, and then supply power to the light-emitting lamp 32.

The advantage of the above arrangement is that since the light-emitting component 3 itself has a power supply module 33, and the power supply module 33 can generate electricity by itself based on the rotation of the rotating component 2 or the output shaft 11 to power the light-emitting lamp 32, the light-emitting component 3 itself does not The need for the supply of electric energy also solves the problem of difficulty in external power supply layout and difficulty in adding light sources. In addition, since the light-emitting component 3 is an integral part, wrapped inside the waterproof housing 31, and then integrally installed on the pulsator 21, this makes installation and replacement without disassembly and assembly of the pulsator 21, output shaft 11 and other structures, and the assembly is extremely Convenience. On the reverse side, if the light-emitting component 3 is split into multiple parts and installed on the pulsator 21 and the inner wall of the washing machine respectively, and the relative movement of the pulsator 21 and the inner wall of the washing machine is used to generate electricity, it is necessary to make the pulsator 21 and the inner wall of the washing machine generate electricity. The overall structure needs to be adjusted. This requires major changes to the molds of the normal production line, which cost a lot of money and cannot be used universally with conventional washing machine production lines. However, the present invention designs it as an integral type and directly installs it on a preset surface of the pulsator 21. There is no need to modify the structure of other parts, and the modification of the pulsator 21 only stays on the surface. The production line of the pulsator 21 mold can still be used without major adjustments, which greatly reduces The feasibility of this application saves production costs.

As shown in Figures 3-6, in a possible implementation, the power supply module 33 includes an annular pipe 331, a coil 332, and a permanent magnet 333. The annular pipe 331 is fixed inside the waterproof housing 31, and the coil 332 is wound around the annular pipe 331. The permanent magnet 333 is movably arranged inside the annular pipe 331 and can move relative to the annular pipe 331 when the rotating part 2 or the output shaft 11 rotates. Preferably, the cross section of the annular pipe 331 is circular, and correspondingly, the permanent magnet 333 is spherical.

The advantage of the above arrangement is that when the pulsator 21 or the output shaft 11 starts to rotate, the waterproof housing 31 fixed on it also rotates, which makes the annular pipe 331 rotate accordingly, but the permanent magnet 333 is in the ring The inside of the pipe 331 can move back and forth. Taking Fig. 6 as an example, when the annular pipe 331 rotates, the permanent magnet 333 will have a lagging movement, which causes relative movement between the two, prompting the coil 332 to cut the magnetic line of induction. Power is supplied to the light-emitting lamp 32. It is preferable to arrange the light emitting component 3 at the center position of the pulsator 21, where the hysteresis motion will be more obvious, and the total amount of generated electric energy is also more, but it is obvious that the light emitting component 3 can also be arranged at other positions of the pulsator 21, such as deviating waves. The center of the wheel 21 only needs to be able to promote the relative movement of the permanent magnet 333 and the coil 332 through the rotation of the pulsator 21. The permanent magnet 333 is set in a circular shape, and the pipe is set into an annular pipe 331 with a circular cross section. First of all, it is easy to select the material. There are many pipes on the market that have a circular cross section, which makes The processing cost is reduced, and the frictional force of the spherical permanent magnet 333 with respect to the annular pipe 331 is smaller, and it rolls in the annular pipe 331 instead of sliding, which can make the relative movement of the coil 332 and the permanent magnet 333 smoother. .

As shown in FIG. 3, in another possible embodiment, the light-emitting lamp 32 is preferably an ultraviolet germicidal lamp. Preferably, the light-emitting component 3 further includes a battery (not shown in the figure), the battery is fixed inside the waterproof housing 31, the power supply module 33 is electrically connected to the battery, and the battery is electrically connected to the light-emitting lamp 32. More preferably, the light-emitting component 3 further includes a circuit board (not shown in the figure), the circuit board is fixed inside the waterproof housing 31, the battery is electrically connected to the circuit board, and the circuit board is electrically connected to the light-emitting lamp 32.

The advantage of the above arrangement is that by adding a battery, the electric energy generated by the power supply module 33 can be stored, which avoids the situation that the light-emitting lamp 32 in the washing machine stops lighting immediately after the washing machine is stopped. The setting of the circuit board enables the user to control the switch or brightness of the light-emitting lamp 32. Furthermore, the light-emitting lamp 32 is of course not limited to lighting lamps (such as LED lamps, incandescent lamps, etc.), but can also be other functional lamps, such as Ultraviolet germicidal lamps, etc., through the combination of ultraviolet germicidal lamps and lighting lamps, enable users to selectively illuminate, sterilize, or perform simultaneously.

As shown in FIG. 1, in another possible embodiment, a first connecting member is provided on the waterproof housing 31, and a second connecting member is provided on the rotating part 2 or the output shaft 11 accordingly. The waterproof housing 31 and the rotating part 2 or the output shaft 11 is detachably connected by the first connecting member and the second connecting member. The first connecting member can be one of a slot and a buckle. Correspondingly, the second connecting member can be another one of a slot and a buckle. The two cooperate to make the waterproof housing 31 detachably connected to the pulsator 21. Or on the output shaft 11, of course, the first connection member and the second connection member can also be other detachable connection structures, for example, the first connection member is a through hole, the second connection member is a threaded hole, and the two are connected by screws, etc. .

The advantage of the above arrangement is that the waterproof housing 31 can obviously be directly installed on the pulsator 21 by welding or integral molding, but if the light-emitting component 3 fails, it cannot be quickly replaced, and this application adds the first connecting member and the first connecting member. The detachable connection of the two connecting members enables the light-emitting component 3 to be flexibly disassembled and replaced.

As shown in FIG. 3, in another possible embodiment, the waterproof housing 31 includes a base 311 and a cover 312. The base 311 is fixed on the rotating component 2 or the output shaft 11, and the cover 312 is arranged on the base. On 311, the base 311 and the cover 312 jointly form a waterproof and airtight cavity, the light-emitting lamp 32 is arranged inside the cover 312, and the power supply module 33 is arranged on the base 311. Among them, the connection between the cover 312 and the base 311 needs to be waterproof, and there are various connection methods, such as glue bonding, ultrasonic welding, screw fastening seal ring, and the like. Preferably, a transparent window 3121 is further provided on the cover 312, and the transparent window 3121 is configured such that the light beam emitted by the light emitting lamp 32 passes through the transparent window 3121 and does not include the clothing inlet of the rotating component 2.

The advantage of the above arrangement is that the waterproof housing 31 can obviously be integrated, but it is easier to process and the design is more reasonable if the waterproof housing 31 is arranged in a separate form. A transparent window 3121 is provided on the cover 312. Preferably, the transparent window 3121 is a window that shields the transparent quartz plate 3122, and the irradiation range of the light beam emitted from the transparent window 3121 does not include the clothing inlet of the rotating part 2, which can avoid causing users It feels dazzling. Furthermore, if the light-emitting lamp 32 is an ultraviolet germicidal lamp, this arrangement also protects the user from ultraviolet rays. Regarding the structure of the transparent window 3121, due to the different installation positions of the light-emitting components 3, it cannot be reasonably limited by physical values. Therefore, a functional limitation method is adopted. Here, for full description, several specific forms are listed. For example, in Figure 1, the structure of the transparent window 3121 should be set such that the minimum angle α between the light emitted and the vertical line should meet the requirement of α≥30°, but if the light emitting component 3 is installed in the pulsator 21 The value of the minimum included angle α should obviously be greater than 30°. For example, α≥50° can satisfy the requirement that it cannot be irradiated to the clothing inlet even during rotation. In addition, as shown in Figure 2, if the light-emitting component 3 is arranged in the drum washing machine, since the size of the drum washing machine inner tub 22 is also different from that of the pulsator washing machine, the inner tub 22 of the same drum washing machine may also have different models due to different models. Therefore, α is difficult to be limited by a specific range, as long as it is not irradiated to the clothing inlet.

2, a brief introduction to other embodiments of the laundry treatment device of the present invention will be given below. The laundry treatment device of the present invention can obviously also be a drum washing machine, or other laundry treatment devices, etc., as long as the power supply module 33 can be installed to generate electricity by itself. can. When the laundry treatment equipment is a drum washing machine, correspondingly the rotating part 2 is the inner tube 22, and the light-emitting part 3 can be installed on the output shaft 11 or any position of the inner tube 22, and preferably can be installed on the inner tube 22 as shown in the figure. The bottom center position.

In summary, the present invention solves the problem of the difficulty of installing power supply inside the washing machine through the self-illumination of the light-emitting component 3, and the overall design is an integrated type, which is directly installed and used, and has little modification to the existing washing machine and has strong implementability. The light-emitting lamp 32 is replaced with a germicidal lamp, which can realize the sterilization function in the washing machine. Add batteries, circuit boards, etc. to make it easier to control.

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 annular pipe 331 of the power supply module 33 can obviously also be replaced with other shapes, such as a straight pipe, etc., as long as the permanent magnet 333 can be relatively displaced in the pipe to make the magnetic field cut The coil 332 on the outside of the pipe can generate current. In addition, the cross section of the annular pipe 331 can obviously also be other shapes, such as rhombus, triangle, rectangle, etc., as long as the permanent magnet 333 can move smoothly in the pipe. Accordingly, the permanent magnet 333 can also be the same as the pipe cross section. Other matching shapes will not be listed one by one. These do 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 washing machine as an example, the laundry treatment equipment of the present invention can obviously also be other equipment, such as a shoe washing machine.

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.
