Description

Technical Field

[0001] This invention belongs to the field of clothing treatment equipment, specifically, it relates to an additive atomization dispensing device, clothing treatment equipment and washing method. Background Technology

[0002] In garment processing equipment, especially laundry equipment, the washing process typically involves adding water and additives into the washing chamber. However, this direct addition method often results in uneven mixing of the additives and water within the washing chamber. This uneven mixing leads to uneven coverage of the additives on the garments, resulting in uneven washing effects and incomplete cleaning.

[0003] To address the aforementioned problems, various methods have been employed in existing technologies. One common method involves rotating the washing drum during water intake, causing the clothes to be continuously agitated and mixed with the wash water. The purpose of this method is to increase the uniformity of additive dispersion on the clothes through physical agitation. However, the effectiveness of this method is limited by factors such as the rotation speed of the washing drum and the texture and quantity of the clothes, thus its effect on improving dispersion uniformity is limited.

[0004] Another method involves adding water and additives by spraying water into the washing drum. This spraying method attempts to avoid concentrating the additives on a particular area of ​​the clothing, thereby improving the evenness of additive dispersion. However, the evenness and coverage of the spray are still limited by the design of the spraying equipment and nozzles, making it difficult to ensure a uniform distribution of the additives throughout the washing chamber and on the clothing.

[0005] Another method involves adding water and additives by spraying them into the washing drum. This is done by introducing compressed gas and liquid into an atomizing nozzle, using the high-pressure gas to atomize and spray the liquid. However, this method suffers from the problem of high gas pressure inside the atomizing nozzle, which prevents the liquid from flowing back into the nozzle smoothly, resulting in poor atomization and spraying effect.

[0006] While the methods described above improve the uniformity of additive dispersion to some extent, they still have many shortcomings. Especially when dealing with large quantities of laundry or heavily stained garments, they often fail to meet users' high demands for washing results. Therefore, it is necessary to develop a more effective and efficient additive dispensing and dispersion technology to further enhance the washing performance of laundry treatment equipment.

[0007] In view of this, the present invention is proposed. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art. The purpose is to provide an additive atomizing and dispensing device, which uses a gas generating device to generate gas to pressurize and output the liquid containing the additive, so that the liquid is delivered to the atomizing module to be atomized with the gas. This not only increases the liquid discharge speed, but also allows the liquid to smoothly enter the atomizing module and be atomized with the gas, thereby spraying and washing the clothes in the clothing treatment equipment and improving the washing effect.

[0009] Another object of the present invention is to provide a garment treatment device, including the above-mentioned additive atomization dispensing device.

[0010] Another object of the present invention is to provide a washing method for a garment processing device.

[0011] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is to provide an additive atomization and dispensing device, including...

[0012] A gas generating device used to generate gas;

[0013] An atomizing module is used to atomize and dispense a liquid containing additives; the gas pressurizes the liquid containing additives and outputs the liquid; the liquid and gas are atomized through the atomizing module.

[0014] Furthermore, the gas generating device delivers two gas streams: one stream delivers gas to the atomizing module, and the other stream outputs gas to deliver the liquid containing additives to the atomizing module.

[0015] Furthermore, after pressurizing the liquid containing the additive, the gas generating device outputs one gas path to the atomizing module and another liquid path to the atomizing module.

[0016] Furthermore, the liquid containing additives is placed in a cavity, one opening of which is connected to a gas generating device, and the liquid outlet of which is connected to an atomizing module.

[0017] Furthermore, the cavity also includes an air outlet connected to the atomizing module for outputting gas to the atomizing module.

[0018] Furthermore, the cavity is provided with a gas region and a liquid region, and the gas outlet of the cavity is connected to the gas region to output gas;

[0019] Preferably, the opening is in communication with the gas region.

[0020] Furthermore, the cavity is configured to deliver the liquid inward, or the cavity is configured to deliver multiple liquids mixed into the liquid inward.

[0021] Furthermore, the cavity has a liquid outlet structure, configured to pressurize the gas input cavity and control the liquid output within the cavity;

[0022] Alternatively, the liquid outlet channel of the cavity may be equipped with an on / off unit, configured to connect the liquid outlet channel after the liquid level in the cavity reaches a preset liquid level.

[0023] The present invention also provides a garment treatment device having any of the above-described additive atomization dispensing devices.

[0024] The present invention also provides a washing method for a garment processing device, which uses any of the above-described dispensing devices to perform additive atomized dispensing and washing.

[0025] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0026] (1) This invention uses gas generated by a gas generating device to pressurize a liquid containing additives, which accelerates the delivery of the liquid to the atomizing module and improves the efficiency of atomization. Simultaneously, the gas generating device also supplies gas to the atomizing module to power liquid atomization, causing the liquid in the atomizing module to be atomized into fine droplets. The atomizing module can then evenly spray these fine droplets onto the fabric in the garment processing equipment, achieving atomized delivery of the additive-containing liquid, improving the utilization efficiency of the additives, and thus enhancing the washing effect. It also saves washing water and electricity consumption.

[0027] (2) The present invention outputs a single gas path from the gas generating device into the cavity, which can pressurize the liquid in the cavity and accelerate the liquid discharge to the atomization module. It can also directly input the gas output from the cavity into the atomization module to provide liquid atomization power, thus producing two functions. The path design is simple and the cost is low.

[0028] (3) If a siphon liquid outlet structure is adopted, when the liquid level is close to the liquid inlet of the siphon liquid outlet structure, gas is introduced into the cavity. The gas squeezes the liquid and triggers the siphon phenomenon. The liquid is discharged from the siphon liquid outlet structure into the liquid outlet channel and further transported to the atomizing module. This enables the liquid to be smoothly transported to the atomizing module. Its structure is simple and the cost is low.

[0029] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0039] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0040] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] like Figures 1 to 5 As shown, this invention provides an additive atomizing dispensing device, which is particularly suitable for the atomizing dispensing of liquids containing additives such as detergents, fabric softeners, disinfectants, and care agents, to achieve efficient treatment of clothing or items containing fabrics. The term "additive" is merely a general term and can refer to any treatment agent existing in liquid or powder form.

[0042] The additive atomization and dispensing device includes a gas generating device 1 and an atomization module 2.

[0043] The gas generating device 1 is used to generate gas. The atomizing module 2 is used to atomize the liquid containing additives into fine droplets. The gas pressurizes the liquid containing additives and outputs the liquid, and the output liquid and gas are atomized in the atomizing module 2.

[0044] The gas generating device 1 is the power source of this invention. It draws in air and compresses it to a certain pressure using an air pump or compressor, and then uses the compressed gas to pressurize the liquid. Preferably, the gas generating device 1 is an air pump, which has the advantages of simple structure, convenient operation, and low cost.

[0045] The atomizing module 2 has a gas channel and a liquid channel inside. Gas is delivered into the gas channel, and the liquid containing additives is delivered into the liquid channel. The internal structure of the atomizing module 2 causes the high-speed flowing gas and the slowly injected liquid containing additives to collide and break apart with each other in a very short time, tearing the liquid into fine droplets.

[0046] The atomizing module 2 in this invention can utilize an existing atomizing nozzle, the structure of which is already known and will not be described in detail here.

[0047] The gas that atomizes the liquid in the atomization module 2 can be gas directly output from the gas generating device 1, or gas output after pressurizing the liquid containing additives, etc.

[0048] The gas generated by the gas generating device 1 can be delivered into the atomizing module 2 to provide power for liquid atomization. The gas output from the gas generating device 1 can also pressurize the liquid containing additives, thereby increasing the speed and pressure of the liquid being delivered to the atomizing module 2, preventing the liquid from flowing back under the pressure of the high-pressure gas, ensuring smooth liquid intake of the atomizing nozzle, and thus improving the efficiency of atomization.

[0049] The liquid in the atomizing module 2 is atomized into fine droplets by the gas. The atomizing module 2 can evenly spray these fine droplets onto the fabric in the washing unit 9 of the garment processing equipment, achieving uniform atomization of the additive-containing liquid onto the fabric, improving the utilization efficiency of the additive, and thus improving the washing effect. At the same time, it saves washing water and electricity consumption.

[0050] When liquid detergent is added, the detergent solution is atomized, filling the drum with tiny detergent droplets. The lipophilic ends of the surfactants are distributed on the surface of these droplets, enhancing the detergent's wetting ability on fabrics and stains. The clothes are tumbled and shaken in the water and detergent mist, allowing for more thorough contact with the detergent and shortening the detergent's action time on the stains, thus improving the detergent's cleaning effect. Simultaneously, the water mist washing method reduces the amount of water used, thereby reducing energy consumption.

[0051] The gas generating device 1 delivers two gas streams to the atomizing module 2. One stream delivers gas to the atomizing module 2 to generate a high-speed airflow. The other stream outputs gas to deliver the liquid containing additives to the atomizing module 2, using gas pressure to push the liquid containing additives into the atomizing module 2. Both streams are atomized in the atomizing module 2.

[0052] One implementation method is, as follows: Figures 1 to 2 As shown, the gas generating device 1 outputs gas to pressurize the liquid containing additives, and then outputs one gas path to the atomizing module 2, and another liquid path to the atomizing module 2.

[0053] After pressurizing the liquid containing additives, the gas generating device 1 delivers the liquid to the atomizing module 2 through the liquid outlet channel 8. During the pressurization process, the gas not only provides the liquid with the driving force for flow, but also provides a high-speed airflow within the atomizing module 2, which fully tears the liquid within the atomizing module 2, thereby forming finer droplets, which are then released into the clothing processing equipment.

[0054] Another implementation method is, as Figures 3 to 4As shown, the gas generating device 1 has one or two outlets, one of which delivers gas to the atomizing module 2, and the other gas pressurizes the liquid containing additives, causing the liquid to be delivered to the atomizing module 2. The delivered gas and the liquid are atomized in the atomizing module 2 and then released into the clothing treatment equipment.

[0055] Another implementation plan is, in Figure 5 In this process, the gas generating device 1 outputs gas to the atomizing module 2. Some of the gas can pressurize the liquid input into the atomizing module 2 and output the liquid to the liquid channel of the atomizing module 2; some of the gas is directly input into the gas channel of the atomizing module 2. The internal structure of the atomizing module 2 causes the high-speed flowing gas and the pressurized liquid to collide and break each other in a very short time, tearing the liquid into fine droplets.

[0056] Furthermore, in some of the above embodiments, the liquid containing the additive can be contained within a cavity 3. Figures 1 to 2 As shown, all the gas generated by the gas generating device 1 passes through the cavity 3. Figures 3 to 4 As shown, part of the gas generated by gas generating device 1 passes through cavity 3. Figure 5 In the middle, the gas generated by the gas generating device 1 does not pass through the container 3.

[0057] like Figures 1 to 4 As shown, one opening 31 of the cavity 3 is connected to the gas generating device 1 to facilitate the introduction of gas into the cavity 3. The liquid outlet 35 of the cavity 3 is connected to the atomizing module 2.

[0058] In this invention, by setting a cavity 3, it is convenient to hold liquid. The gas generating device 1 can introduce gas into the cavity 3 through the opening 31. The gas compresses the liquid in the cavity 3, causing the liquid to be discharged from the outlet 35 of the cavity 3, thus realizing the introduction of gas and the discharge of liquid.

[0059] In a preferred embodiment, the cavity 3 further includes an outlet 34 connected to the atomizing module 2 for outputting gas to the atomizing module 2. After the gas generating device 1 introduces gas into the cavity 3, it causes the liquid to be transported from the liquid outlet 35 to the atomizing module 2. The gas is output from the outlet 34 of the cavity 3 and then transported to the atomizing module 2 to atomize the liquid in the atomizing module 2.

[0060] More preferably, the gas generating device 1 has an outlet that is connected to the opening 31 of the cavity 3 so as to allow gas to be introduced into the cavity 3.

[0061] This invention outputs a single gas path from the gas generating device 1 into the cavity 3, which can both pressurize the liquid in the cavity 3 to accelerate its discharge to the atomizing module 2 and directly input the gas output from the cavity 3 into the atomizing module 2 to provide power for liquid atomization, thus achieving two functions. The path design is simple and the cost is low.

[0062] The cavity 3 may be located inside a container (see [reference]). Figures 1 to 4 The gas generating device 1 introduces gas into a container containing the liquid. The container can be an existing separate container in the clothing processing equipment, such as a detergent dispenser, or it can be a newly added container with a certain volume.

[0063] The container is capable of storing liquid to a certain height. The container is a closed container, such as a box or can.

[0064] Furthermore, the cavity 3 is configured to deliver the liquid into it, or the cavity 3 is configured to deliver multiple liquids mixed into the liquid into it.

[0065] Specifically, the liquid is a premixed liquid of additives and water, which is directly delivered into the cavity 3. The cavity 3 is provided with a liquid inlet 32, and the outside of the cavity 3 is provided with a liquid inlet channel 5 communicating with the liquid inlet 32 ​​for introducing liquid into the cavity 3.

[0066] Alternatively, the liquid may be a mixture of additives, water, and other liquids added to the cavity 3. The cavity 3 is provided with a water inlet 33 and a liquid inlet 32. An inlet channel 6 communicating with the water inlet 33 is provided on the outside of the cavity 3 for introducing water into the cavity 3. An inlet channel 5 communicating with the liquid inlet 32 ​​is provided on the outside of the cavity 3 for introducing liquid into the cavity 3.

[0067] Alternatively, the liquid may be a commercially available diluted additive liquid, automatically or manually delivered into the cavity 3.

[0068] Alternatively, the liquid is an additive liquid, which is automatically or manually delivered into the cavity 3.

[0069] The premixing ratio of additives and water is adjusted according to the characteristics of the additives, such as their density and the content of active ingredients.

[0070] One-way valves 51 are provided on the liquid inlet channel 5 and / or water inlet channel 6.

[0071] Furthermore, the cavity 3 is provided with a gas region and a liquid region. The gas outlet 34 of the cavity 3 is connected to the gas region to output gas. The liquid outlet channel 8 of the cavity 3 outputs from the liquid region within the cavity 3.

[0072] The gas region within cavity 3 refers to the region that remains empty during the operation of cavity 3. This allows the outlet 34 of cavity 3 to be located within the gas region, facilitating the discharge of incoming gas through the outlet 34. The outlet 34 of cavity 3 connects to the jetting area of ​​atomizing module 2. Since the jetting area is small and the gas output of atomizing module 2 is low, while the air intake of cavity 3 is large, introducing gas into cavity 3 pressurizes its interior. This pressurization causes liquid to exit through outlet 35, accelerating liquid drainage, while gas exits from the gas region through outlet 34, increasing gas pressure and facilitating the high-speed movement of gas within atomizing module 2 to tear the liquid into droplets.

[0073] The liquid region within the cavity 3 is used to store and supply liquid containing additives. The liquid outlet 35 of the cavity 3 is located in the liquid region, or the liquid outlet 35 is located close to the liquid region.

[0074] The air outlet 34 is connected to the outside of the atomizing module 2. The air outlet 34 can balance the internal and external air pressure of the cavity 3 when liquid is introduced into the cavity 3, so as to ensure the smoothness of liquid and / or water introduction into the cavity 3.

[0075] Preferably, the opening 31 is connected to the gas region. It is connected to the atomizing module 2 via the air outlet 34. The opening 31 for air intake is located in the gas region of the cavity 3, allowing the gas generated by the gas generating device 1 to be directly input into the gas region, directly pressurizing the existing air in the gas region, promoting liquid discharge, accelerating liquid discharge efficiency and gas outlet speed, thereby improving atomization spraying efficiency.

[0076] A gas region is reserved at the top of cavity 3, and a liquid region is reserved at the bottom of cavity 3. Gas can be introduced after liquid has been introduced into cavity 3.

[0077] One liquid outlet configuration is that the cavity 3 has a liquid outlet structure, which is configured to pressurize the gas input cavity 3 to control the liquid output within the cavity 3, thereby providing dehumidification power for the liquid output.

[0078] If a siphon liquid outlet structure 37 is used, when the liquid level is close to or higher than the liquid inlet of the siphon liquid outlet structure 37, gas is introduced into the cavity 3. The gas compresses the liquid, triggering a siphon phenomenon. The liquid is discharged from the siphon liquid outlet structure 37 into the liquid outlet channel 8, and further transported to the atomizing module 2, which enables the liquid to be smoothly transported to the atomizing module 2. Its structure is simple and low in cost.

[0079] Another solution for liquid discharge is that the liquid discharge channel 8 of the cavity 3 is equipped with an on / off unit, which is configured to connect the liquid discharge channel 8 after the liquid level in the cavity 3 reaches a preset liquid level.

[0080] The on / off unit can be located at the connection between the liquid outlet channel 8 and the liquid outlet 35, or it can be located at other positions in the liquid outlet channel 8 to achieve flexible control. When there is a certain liquid level in the cavity 3, the on / off unit can be controlled to disconnect, so that the liquid outlet channel 8 is connected and the liquid is transported to the atomizing module 2.

[0081] In one specific embodiment of the present invention, the additive enters the cavity 3 through the liquid inlet 5 and the liquid inlet 32 ​​via the liquid inlet channel 5 for mixing. When the liquid level in the cavity 3 reaches a preset level, the gas generating device 1 is activated to generate gas. The gas enters the cavity 3 through the air inlet channel 4 and the opening 31. Under the action of gas pressure, the liquid containing the additive is transported from the liquid outlet 35 and the liquid outlet channel 8 to the atomizing module 2. At the same time, some gas reaches the atomizing module 2 through the air outlet 34 and the air outlet channel 7. The atomizing module 2 further breaks down the liquid and gas containing the additive into tiny droplets, which are sprayed from the window gasket of the washing machine drum onto the clothes to be washed inside the drum, achieving atomized dispensing of the liquid containing the additive, improving the washing ratio, and saving water.

[0082] The present invention also provides a garment treatment device having any of the above-described additive atomization dispensing devices.

[0083] In the washing process, the garment processing equipment of the present invention uses an additive atomizing dispensing device to evenly dispense additives in an atomized form into the garment processing equipment, ensuring that the additives can fully act on the garments or other items to be washed. Because the additives are dispensed in a mist form, they can mix better with the garments in the washing unit 9, thereby improving the washing effect.

[0084] The garment processing equipment includes washing machines, shoe washing machines, and dryers. Furthermore, when the garment processing equipment is a washing machine, a liquid containing additives can be atomized and dispensed into the washing unit 9. When the garment processing equipment is a dryer, a liquid containing conditioning agents can be directly atomized and dispensed into the washing unit 9 using a dispensing device.

[0085] Preferably, the clothing processing device is a washing machine, and the washing unit 9 is a washing drum. The opening of the washing drum faces forward.

[0086] The present invention also provides a washing method for a garment processing device, which uses any of the above-described dispensing devices to perform additive atomized dispensing and washing.

[0087] A gas generating device outputs gas to pressurize a liquid containing additives. The liquid is then output to an atomizing module, where the gas is also delivered and atomized with the liquid. The atomizing module sprays the atomized liquid into the garment treatment equipment, allowing washing to occur during or after spraying.

[0088] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
