Description

Technical Field

[0001] This invention relates to the field of household appliance technology, specifically providing a clothing processing device. Background Technology

[0002] Clothing treatment devices, as an indispensable appliance in modern homes, integrate multiple functions such as washing, spin-drying, and drying, including but not limited to traditional washing machines and washer-dryer combos. Currently, most clothing treatment devices on the market are equipped with advanced sterilization devices, employing diverse sterilization technologies to meet the needs of different scenarios. Among them, ultraviolet (UV) technology is known for its high efficiency, but special care must be taken to avoid direct exposure to the eyes and skin to prevent potential harm; silver ion technology has won market favor due to its powerful antibacterial and deodorizing abilities; however, the potential health problems caused by excessive absorption should not be ignored; and high-temperature treatment, as one of the most traditional sterilization methods, while effectively inactivating pathogens, may cause irreversible damage to clothing containing special materials (such as silk and wool), affecting the fabric's texture.

[0003] In view of this, patent CN116949759A discloses a clothing treatment device that integrates electrolytic steam sterilization technology. Its core components include a washing tub for containing wash water, a steam generator, and a sterilization device containing a reaction chamber. The steam generator is located on the washing tub or circulating air duct, and converts the wash water into steam through a heating element, releasing it into the circulating air duct or directly into the reaction chamber. Inside the reaction chamber, the steam undergoes an electrolysis process, primarily using a corona discharge region to convert water molecules into hydrogen peroxide. However, the steam temperature is high, and the hydrogen peroxide is unstable and easily decomposes as it enters the washing tub with the high-temperature steam, resulting in poor sterilization effect on clothing.

[0004] Accordingly, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0038] As Figures 1-2 To solve the problem that hydrogen peroxide is unstable and easy to decompose in the process of entering the washing tub with high temperature vapor, resulting in poor sterilization effect on clothes, the present application provides a clothes treatment device, which comprises: a water storage box 1 for containing washing water; a washing tub 2 in fluid communication with the water storage box 1; a hydrogen peroxide unit 3 arranged in the water storage box 1 and configured to generate hydrogen peroxide by electrolysis of washing water; and an ultrasonic atomization unit 4 arranged between the water storage box 1 and the washing tub 2 and configured to atomize and transmit the washing water containing hydrogen peroxide to the washing tub 2. In this way, the hydrogen peroxide unit 3 is arranged in the water storage box 1 to generate hydrogen peroxide, and the ultrasonic atomization unit 4 atomizes the washing water containing hydrogen peroxide by ultrasonic atomization technology and transmits it to the washing tub 2. The problem of instability of hydrogen peroxide caused by electrolysis in high temperature environment is effectively avoided, and the sterilization effect is improved. The atomized hydrogen peroxide can fully contact with the clothes to be washed in the washing tub 2, improving the utilization rate of hydrogen peroxide. At the same time, hydrogen peroxide as a strong oxidizing agent has high efficiency and broad spectrum sterilization ability, and is friendly to the material of clothes and will not cause irreversible damage.

[0039] Figure 1 is the overall cross-sectional structure schematic diagram of the first embodiment of the clothes treatment device of the present application; Figure 2 is the cross-sectional structure schematic diagram of the water storage box of the first embodiment of the clothes treatment device of the present application.

[0040] As Figure 1As shown in the drawings, in one or more embodiments, the clothes treating apparatus of the present application is a drum-type washing machine. The clothes treating apparatus comprises a housing 6, the upper side of which is provided with a horizontally arranged panel 61, and the lower end of which is provided with a foot 62 near each of the four corners. The housing 6 is supported by the feet 62.

[0041] It should be noted that, although the clothes treating apparatus of the present application is described in terms of a drum-type washing machine, this is not limiting, and those skilled in the art can apply the present application to any other clothes treating apparatus, such as an impeller-type washing machine, as long as the clothes treating apparatus needs to be sterilized.

The water storage body 16 is a cylindrical structure with an open upper end, and the water storage body 16 is provided with a water inlet pipe 12 near the opening direction, through which water can be added to the water storage body 16. The lower end of the water storage body 16 is provided with an atomizing hole 161, and the lower end of the atomizing hole 161 is provided with an ultrasonic atomizing unit 4. The washing water atomized by the ultrasonic atomizing unit 4 can enter the water storage body 16 through the atomizing hole.

[0045] It should be noted that the above-mentioned water storage body 16 is not unique, and those skilled in the art can choose the specific structure of the water storage body 16 based on the specific application scenario. For example, the water inlet pipe 12 can be located at any position of the water storage body 16, as long as water can be added to the water storage body 16.

Specifically, the air inlet 1511 and the mist guiding outlet 1521 are arranged on the water storage cover 15, so that the air can enter the water storage body 16, and the atomized washing water can be discharged from the water storage body 16. For another example, the water storage cover 15 can be a flat plate, and the water storage cover 15 is sealingly connected to the upper end opening of the water storage body 16. Correspondingly, the air inlet 1511 and the mist guiding outlet 1521 are both arranged on the water storage body 16. For another example, the water storage box 1 can be integrally formed, and can accommodate washing water. Correspondingly, the air inlet 1511 and the mist guiding outlet 1521 are both arranged on the water storage box 1.

[0048] As Figure 2As shown, the hydrogen peroxide unit 3 is arranged in the water storage box 1. In one or more embodiments, the hydrogen peroxide unit 3 is internally provided with an electrode, which is sprayed with a nano-carbon-based catalyst, specifically, pyrrole butyric acid and an ethylene oxide-propylene oxide-ethylene oxide three-segment copolymer are subjected to polymerization reaction to form a polymer, and then carbonization is performed to spray on the electrode, thereby having high hydrogen peroxide selectivity and catalytic activity, and efficiently generating hydrogen peroxide. The electrode includes an anode electrode and a cathode electrode, the anode electrode is connected to the positive pole of the power supply, and the cathode electrode is connected to the negative pole of the power supply, so as to facilitate electrolysis of water.

[0049] It should be noted that the structure of the hydrogen peroxide unit 3 described above is a prior art, and those skilled in the art can select the hydrogen peroxide unit 3 according to different application scenarios, as long as it can prepare hydrogen peroxide.

[0050] As shown in Figure 1 and Figure 2 In one or more embodiments, the fan 1514 is located in the first cavity 151, and the fan 1514 can blow the air at the air inlet 1511 to the first mounting port 1512 and into the water storage body 16 through the first mounting port 1512. The fan drive 11 is connected to the outside of the water storage cover 15, the drive shaft of the fan drive 11 penetrates the side wall of the water storage cover 15 and is connected to the fan 1514, and the fan drive 11 can drive the water storage box 1 to rotate. Placing the fan 1514 in the first cavity 151 can avoid the influence of atomized hydrogen peroxide on the fan 1514, thereby improving the reliability of the equipment.

[0051] It should be noted that the fan 1514 and the fan drive 11 are not necessarily provided, and those skilled in the art can select whether to provide the fan 1514 and the fan drive 11 and the specific structure of the fan 1514 and the fan drive 11 based on specific application scenarios. For example, the fan 1514 can be arranged on the outside of the water storage box 1 and communicate with the air inlet 1511. The fan 1514 accelerates the air input into the water storage box 1. For another example, the fan drive 11 can also be connected to the shell 6. Of course, the fan 1514 and the fan drive 11 can also not be provided.

[0052] As shown in Figure 2As shown, in one or more embodiments, a first valve 1513 is arranged at the lower end of the first installation port 1512, and the first valve 1513 can control the opening and closing of the first installation port 1512. Precise control of the air flow is achieved, ensuring that the air can be directed to blow into the water storage body 16, and the first valve 1513 can adjust the air volume as needed, facilitating control of the air volume. Alternatively, the first valve 1513 can not be arranged. In one or more embodiments, a second valve 1523 is arranged at the upper end of the second installation port 1522. By controlling the second valve 1523, precise output of the atomized hydrogen peroxide is achieved. Alternatively, the second valve 1523 can not be arranged.

Alternatively, the mist outlet pipe 13 can not be arranged, and the atomized washing water is sprayed from the mist outlet guide 1521. Alternatively, the spray head 14 can not be arranged.

[0054] As shown, Figure 2 The ultrasonic atomization unit 4 is arranged between the water storage box 1 and the washing tub 2 and can atomize and transmit the washing water containing hydrogen peroxide to the washing tub 2. In one or more embodiments, an installation protrusion 162 is arranged outside the atomization hole 161 at the bottom of the water storage box 1, and the installation protrusion 162 is coaxially arranged with the atomization hole 161. The ultrasonic atomization unit 4 includes an ultrasonic sheet 41, a sealing flange 43, and a sealing member 44. The sealing flange 43 is provided with a connecting lug on the outer peripheral surface, and the connecting lug is sealingly connected to the installation protrusion 162 by a bolt.
