Description

Technical Field

[0001] This utility model relates to a laundry detergent storage device, and more particularly to a laundry detergent dispenser for use in a washing machine. This utility model also relates to a laundry detergent dispensing module and a clothing washing device. Background Technology

[0002] With the improvement of people's living standards, washing machines have become an indispensable household appliance in daily life. Currently, washing machines on the market are becoming increasingly sophisticated in function and more intelligent. One of the key elements in the washing process is the use of laundry detergent. The composition of laundry detergent itself is determined by national standards or the manufacturer, and has little to do with the structure of the washing machine. However, in the intelligent dispensing module of washing machines, the current detergent dispenser only functions to store detergent, offering only a single function. Furthermore, volatile substances in laundry detergent are prone to evaporate during storage, shortening its shelf life and failing to effectively extend its expiration date. If a structure could be added to the intelligent dispensing dispenser to enhance the detergent's effectiveness, a significant breakthrough in cleaning performance could be achieved. Utility Model Content

[0003] The first technical problem to be solved by this utility model is to provide a laundry detergent dispenser that can introduce plasma into laundry detergent to improve the cleaning effect, in view of the above-mentioned technical status.

[0004] The second technical problem to be solved by this utility model is to provide a laundry detergent delivery module that can introduce plasma into laundry detergent to improve the cleaning effect, in view of the above-mentioned technical status.

[0005] The third technical problem to be solved by this utility model is to provide a washing machine that can introduce plasma into the laundry detergent to improve the cleaning effect, in view of the above-mentioned technical status.

[0006] The technical solution adopted by this utility model to solve the first technical problem mentioned above is as follows: a laundry detergent dispensing box, including a box body for storing laundry detergent, characterized in that the box body has an upper port, and an upper cover is provided on the upper port. A high-position electrode and a dielectric plate are arranged sequentially from top to bottom on the lower end surface of the upper cover facing the inner cavity of the box body. The aforementioned high-position electrode is externally connected to a plasma power supply. The aforementioned high-position electrode, dielectric plate and laundry detergent serving as a low-position electrode in the box body constitute a barrier dielectric discharge structure.

[0007] Preferably, the high-position electrode is bonded to the lower end surface of the upper cover, and the dielectric plate is bonded to the lower end surface of the high-position electrode.

[0008] Furthermore, the upper cover has an opening for adding laundry detergent, and the opening is equipped with a flip-up cover.

[0009] The thickness of the dielectric substrate is 1mm to 2mm, with 1.5mm being optimal.

[0010] The technical solution adopted by this utility model to solve the second technical problem mentioned above is: a laundry detergent dispensing module, including a base, a laundry detergent dispensing box and a pump assembly.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1 As shown, in this embodiment, the washing machine includes a washing machine 100 below and a dryer 101 above. The washing machine 100 includes a body 102, a washing tub (not shown in the figure) and a detergent dispensing module 10. A door 103 is provided on the port of the washing tub. The washing tub is located inside the body 102. The detergent dispensing module 10 is located on the body 102 and below the washing tub.

[0022] like Figure 2 , Figure 3 and Figure 4 As shown, the laundry detergent dispensing module 10 in this embodiment includes a base 2, a box 1, and a pump assembly 3. The laundry detergent dispensing box is slidably mounted on the base 2, and the pump assembly 3 is mounted on the base 2 and can deliver the laundry detergent in the box 1 into the washing tub.

[0023] The housing 1 has an upper port, on which an upper cover 4 is provided. On the lower end face of the upper cover 4 facing the inner cavity of the housing 1, a high-position electrode 7 and a dielectric plate 6 are arranged sequentially from top to bottom.

[0024] The top cover 4 has an inlet 41 for adding laundry detergent, and the inlet 41 has a cover plate 5 that can be flipped up.

[0025] The high-position electrode 7 is bonded to the lower end surface of the upper cover 4, and the dielectric plate 6 is bonded to the lower end surface of the high-position electrode 7.

[0026] Combination Figure 5 As shown, the base 2 is provided with a guide rail 21, and correspondingly, the bottom of the box 1 has a guide rib 11 that cooperates with the guide rail 21.

[0027] Combination Figure 6 As shown, the high-position electrode 7 is connected to an external plasma power supply, and the high-position electrode 7, the dielectric plate 6, and the laundry detergent inside the box 1, which acts as the low-position electrode, constitute a structure that blocks dielectric discharge.

[0028] The high-position electrode is connected to the plasma power source, providing energy. The laundry detergent acts as the low-position electrode, enabling conductivity. The area indicated by the arrow contains plasma-active substances that can enter the laundry detergent below, allowing these active substances to enter the washing machine and participate in the washing process. Substances rich in hydroxyl radicals further enhance the cleaning effect.

[0029] The electrode material is often chosen to be titanium. When a high-position electrode is connected in the diagram, the current breaks down the air in the middle to discharge. The dielectric plate can be made of quartz, glass, or alumina. The thickness of the dielectric plate can be selected from 1mm to 2mm. It is made of inert material to avoid introducing other impurities during plasma treatment that could contaminate the laundry detergent and clothes. The thicker the dielectric plate, the more difficult it is to penetrate the medium, and the higher the power required. Based on the actual diameter of the drum and usage conditions, this embodiment uses a thickness of 1.5mm, and the plasma module power is set to 100W. In actual use, a treatment time of 30s to 120s is sufficient depending on the quality of the laundry detergent.

[0030] The dielectric plate is made of quartz material and has two functions: first, it blocks discharge; second, it limits the position of the high-position electrode.

[0031] Plasma technology, as a scientific and technological means, has already found numerous applications in sterilization and disinfection. In addition, many active substances generated by plasma, such as hydrogen peroxide, ozone, and hydroxyl radicals, can play a role in the washing process, improving the washing efficiency. Further experiments have shown that hydrogen peroxide can further decompose into hydroxyl radicals during the washing process. These hydroxyl radicals can help break down stains into smaller molecules that can be further removed from the surface of clothing.

[0032] Hydrogen peroxide is a weak acid, so a certain alkaline environment is needed for its decomposition into hydroxyl radicals. Currently, many laundry detergents are weakly alkaline to enhance cleaning power, making the decomposition of hydrogen peroxide a suitable environment for laundry detergent. Therefore, plasma treatment within the detergent dispenser is an excellent option. Adding a plasma generator to the top of the dispenser does not interfere with the user's normal detergent dispensing, but allows the circuit to be activated even when the dispenser is completely closed, initiating plasma treatment of the detergent within the dispenser to further increase the number of hydroxyl radicals and improve cleaning performance.
