Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of clothing processing, and in particular provides a clothing processing device. Background Art
[0002] Existing washing machines generally use ordinary detergents to wash clothes, but ordinary detergents cannot remove odors and bacteria and viruses on clothes, nor can they wash clothes made of silk, wool and other materials that are afraid of high temperatures. Some detergents can make clothes hard and even be harmful to human health.
[0003] Existing washing machines are generally double-drum, with the outer drum used to hold water and the inner drum rotating for washing. There will be dirt between the outer drum and the inner drum, and it is easy for bacteria to breed and produce odor in a high humidity environment. Especially for washing machines that have been used for a long time, you will smell a smell when you open them, and bacterial growth may also affect the health of users through the washed clothes. In addition to washing machines, there are also clothing processing equipment such as dryers and clothing care machines, but the air ducts of dryers and clothing care machines are difficult to clean, which will cause mold and bacteria to grow over time and produce odor.
[0004] At present, some clothing processing equipment uses ultraviolet light, ozone, nano silver ions and other methods to sterilize clothing, but these methods have their own shortcomings. Although ultraviolet light can kill bacteria on clothing, it is necessary to pay attention to the exposure time, otherwise it is easy to cause aging and damage to the clothing, and the clothing is generally overlapped when washed. Ultraviolet light can only kill bacteria on the surface of the clothing, and cannot have a sterilization effect on the obscured clothing, so the sterilization effect is not ideal; the sterilization effect of ozone is okay, but ozone is a strong oxidant with a strong bleaching effect, so it is not suitable for washing colored clothing, and the clothing needs to be classified during actual use; some silver ion sterilization methods are to place silver ions in the lifting ribs of the washing tub and release them when they come into contact with water, but the silver ions become less and less with use and cannot be replenished.
[0005] Accordingly, the art needs a new clothes processing device to solve the above problems. Summary of the invention

The negative pressure generated by the negative pressure area will suck the gas in the cleaning material manufacturing device into the connecting pipeline.
[0007] In the above-mentioned specific embodiment of the clothing processing device, the cleaning substance manufacturing device includes: a shell, the shell is arranged on the casing, and the output pipe is connected to the shell; an ozone generator, the ozone generator is arranged in the shell and is used to produce ozone; a superoxide substance manufacturing device, the superoxide substance manufacturing device is arranged in the shell, and the superoxide substance manufacturing device is used to decompose ozone into superoxide substances; by changing the power of the superoxide substance manufacturing device, the decomposition ratio of ozone will change accordingly.

In addition, ordinal numbers such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0023] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0024] Furthermore, in order to more clearly demonstrate the core technical solution of the present invention, the description of the well-known structure of the drum washing machine is omitted in the following description. However, this omission is only for the convenience of description and does not mean that the drum washing machine can be without these structures.
[0025] like Figure 1 As shown, the present invention proposes a clothing processing device, including a casing 1 and a washing chamber 2 in the casing 1, and also includes: a cleaning material manufacturing device, the cleaning material manufacturing device has an output pipe 6, and the cleaning material manufacturing device generates oxidizing cleaning material after being energized, and the oxidizing cleaning material is output through the output pipe 6; a connecting pipe 7, and the water outlet of the connecting pipe 7 is connected to the washing chamber 2; a venturi tube 8, the venturi tube 8 is arranged in the connecting pipe 7, the water flow direction in the venturi tube 8 is consistent with the water flow direction in the connecting pipe 7, when the water flow in the connecting pipe 7 flows through the venturi tube 8, a negative pressure zone will be formed, the connecting pipe 7 is connected with the outlet of the output pipe 6, and the outlet of the output pipe 6 is located in the negative pressure zone, and the negative pressure generated by the negative pressure zone will suck the gas in the cleaning material manufacturing device into the connecting pipe 7.
[0026] In this embodiment, in order to solve the problem of poor sterilization effect of existing clothing processing equipment, a cleaning material manufacturing device is provided. The cleaning material manufacturing device can produce various superoxide substances such as ozone, hydrogen peroxide, hydroxyl free radicals, etc. as cleaning substances. These superoxide substances have strong oxidizing properties and can destroy the molecular protein structure of bacteria and viruses, play a role in sterilization and disinfection, and prevent the growth of bacteria that cause odors. In addition, strong oxidizing substances can also oxidize odor molecules to eliminate odors. These superoxide substances are mixed with water to make the water have a cleaning effect, remove dust and dirt from clothing fibers, and can also remove old detergents remaining in clothing to make the clothing softer.
[0027] Compared with the prior art, the present invention can simultaneously achieve the functions of sterilization and odor removal, and can also restore the original softness of the fabric, thereby improving the washing effect, especially for clothes that cannot withstand high temperatures. It has a better sterilization effect, is easy to decompose, and will not have any detergent residue, and will not have any effect on the human body.
[0028] After some clothing processing devices have processed clothing, some moisture will remain inside, which provides conditions for bacterial reproduction, and simple ventilation cannot prevent bacterial growth. In fact, some ventilation processes will accelerate the spread of odor in the device. The cleaning substance produced in the present invention is injected into the washing chamber 2 together with water, which can sterilize and remove odors where the washing water passes, preventing them from continuing to reproduce and produce odors, especially the position between the outer drum 10 and the inner drum 9 which is difficult to clean and easy to accumulate magazines.
[0029] In addition, the oxidizing cleaning substances produced by the cleaning substance manufacturing device generally exist in the gas. The uniformity of mixing of these gases with washing water will also affect the sterilization and deodorization effect. Therefore, in order to improve the uniformity of mixing of the gas containing the mixed cleaning substances and the washing water, a Venturi tube 8 is provided. Since the superoxide substance needs to be mixed with the water entering the washing chamber 2, the water outlet of the selected connecting pipe 7 must be connected to the washing chamber 2. The Venturi tube 8 is provided in the connecting pipe 7. The water flows through the connecting pipe 7 through the Venturi tube 8. The Venturi tube 8 will form a negative pressure zone. The connecting pipe 7 is connected to the outlet of the output pipe 6 and then connected to the negative pressure zone. When the water flow in the connecting pipe 7 flows through the Venturi tube 8, negative pressure is generated. The negative pressure sucks the superoxide substance in the shell 3 into the connecting pipe 7 through the output pipe 6, so that the superoxide substance and the water in the connecting pipe 7 are evenly mixed.
[0030] Since the cleaning material manufacturing device needs to be powered on for use, in order to prevent water from splashing during the washing process, which would cause the circuit to come into contact with water and generate a risk of electricity use, the Venturi tube 8 provided in the present invention can also separate water and electricity, and the superoxide substance is sucked away through the output pipe 6. In this way, even if the Venturi tube 8 is damaged or the connecting pipe 7 leaks, it will not affect the electrical safety of the cleaning material manufacturing device, thereby greatly reducing the risk of electricity use.
[0031] Furthermore, the cleaning substance manufacturing device includes: a shell 3, the shell 3 is arranged on the casing 1, and the output pipe 6 is connected to the shell 3; an ozone generator 4, the ozone generator 4 is arranged in the shell 3 and is used to manufacture ozone; a superoxide substance manufacturing device 5, the superoxide substance manufacturing device 5 is arranged in the shell 3, and the superoxide substance manufacturing device 5 is used to decompose ozone into superoxide substances; the power of the superoxide substance manufacturing device 5 is adjustable, and by changing the power of the superoxide substance manufacturing device 5, the decomposition ratio of ozone will change accordingly.
[0032] In the present invention, the ozone generator 4 can be selected to use a mercury lamp or an active oxygen generating electrode, and the superoxide substance manufacturing device 5 can be selected to use an ultraviolet lamp bead with adjustable power. Ozone is decomposed into superoxide substances such as hydroxyl free radicals under the irradiation of the ultraviolet lamp. By changing the power or irradiation time of the superoxide substance manufacturing device 5, the decomposition ratio δ of ozone will change accordingly, 0≤δ≤1; when the power of the superoxide substance manufacturing device 5 is zero, δ=0, and ozone will not be decomposed at this time; the greater the power of the superoxide substance manufacturing device 5 or the longer the irradiation time, the closer δ is to 1. The larger δ is, the better the sterilization and deodorization effect is, but the cost issue is often considered in actual generation. The larger δ is, it means that the power of the superoxide substance manufacturing device 5 needs to be increased or the irradiation time needs to be extended, and the cost of the clothing processing equipment will also increase accordingly. In order to reasonably control the cost, the power of the superoxide substance manufacturing device 5 can be adjusted according to the actual situation.
[0033] In order to further prevent water from entering the shell 3, a waterproof and breathable component can be arranged between the shell 3 and the output pipe 6. The waterproof and breathable component can only allow gas to pass through. Under the action of the waterproof and breathable component, the washing water will not enter the shell 3 through the output pipe 6, thereby ensuring the stable operation of the ozone generator 4 and the superoxide substance production device 5.
[0034] Those skilled in the art can select a suitable waterproof and breathable component according to actual conditions, and may select a waterproof and breathable membrane or a solenoid valve.
[0035] Furthermore, the connecting pipe 7 continuously draws gas from the shell 3 through the output pipe 6, so the shell 3 also needs to be connected with the outside to ensure the supply of gas.
[0036] Furthermore, the inner surface of the shell 3 may be coated with titanium dioxide (TiO2), or solid particles of titanium dioxide (TiO2) may be placed in the shell 3 to enhance the effect of generating living oxygen and other oxides.
[0037] Furthermore, the clothing processing device also includes: an outer drum 9, which is arranged in the casing 1, the outer drum 9 is used to hold water, and a washing chamber 2 is formed in the outer drum 9; an inner drum 10, which is arranged in the outer drum 9, the inner drum 10 is connected to the outer drum 9, the inner drum 10 rotates relative to the outer drum 9, and the clothes are prevented from being washed in the inner drum 10; the water outlet of the connecting pipe 7 is arranged between the inner drum 10 and the outer drum 9, so that the water mixed with superoxide first flows into the space between the inner drum 10 and the outer drum 9 and mixes with the water in the washing chamber 2, and then flows into the inner drum 10 to contact the clothes, so that the superoxide can be mixed more evenly and the effect of treating clothes is better.
[0038] Furthermore, in order to make the water flow and superoxide substances mix more evenly, a filter screen is provided on the water outlet of the connecting pipe 7. When the water flow mixed with superoxide substances flows out of the connecting pipe 7, it is further divided by the filter holes of the filter screen, and the superoxide substances and water are further mixed.
[0039] Furthermore, the water inlet of the connecting pipe 7 can be connected to an external water source, so that the connecting pipe 7 is equivalent to a water inlet pipe, and the original water inlet pipe of the clothing processing device can be used, and no additional water pipe is needed. When the connecting pipe 7 is a water inlet pipe, a water inlet valve can be provided on the connecting pipe 7 to control the size of the water flow in the connecting pipe 7.
[0040] Further, if Figure 2 As shown, in order to improve the washing effect, some clothes processing equipments are provided with a circulation pump 11, which is used to pump water at the bottom of the washing chamber 2 into the connecting pipe 7, and then spray it out from the top of the washing chamber 2. Therefore, the water inlet of the connecting pipe 7 can be connected to the bottom of the washing chamber 2 in addition to being connected to the external water source. A part of the water at the bottom of the washing chamber 2 is pumped into the connecting pipe 7 by the circulation pump 11, and superoxide is sucked in through the venturi tube 8 provided in the pipe, and then sprayed from the top of the washing chamber 2 after mixing. Those skilled in the art can choose how to set the connecting pipe 7 according to actual conditions, and can use the water inlet pipe as the connecting pipe 7, or use the pipe for pumping water by the circulation pump 11 as the connecting pipe 7, or add an additional pipe as the connecting pipe 7.
[0041] Further, the shell 3 is connected to the outside through a through hole, and the through hole and the inlet of the output pipe 6 are respectively arranged on two opposite inner walls of the shell 3. The larger the distance between the through hole and the inlet of the output pipe 6, the better. It is best that the through hole and the inlet of the output pipe 6 are separated by the ozone generator 4 and the superoxide substance manufacturing device 5, and can be staggered, so that the content of superoxide substances in the air extracted by the output pipe 6 is higher. That is, the air enters the shell 3 through the through hole, generates superoxide substances after passing through the ozone generator 4 and the superoxide substance manufacturing device 5, and then is extracted by the output pipe 6, so that the water in the connecting pipe 7 can be fully mixed with the superoxide substances; if the through hole and the inlet of the output pipe 6 are close to each other, the air enters the shell 3 through the through hole, and may be extracted by the output pipe 6 before passing through the ozone generator 4 and the superoxide substance manufacturing device 5, resulting in that the water in the connecting pipe 7 cannot be mixed with the superoxide substances, and the effect of sterilization and odor removal cannot be achieved.
[0042] The through hole can be connected to the outlet of the air pump to transport gas into the shell 3 through the through hole; if the through hole is directly connected to the outside world, a waterproof and breathable membrane can also be provided on the through hole to prevent external water vapor from entering the shell and causing electrical hazards.
[0043] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying 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.
