Description

Technical Field

[0001] This invention relates to the field of clothing processing technology, and specifically provides a control method for clothing processing equipment. Background Technology

[0002] As people's living standards improve, washing machines are being used more and more frequently in daily life. When users need to wash clothes, they simply put the clothes and detergent into the washing machine drum and run the machine to clean them. However, this method of washing with water can only remove stains from clothes; it cannot remove bacteria, viruses, or other contaminants.

[0003] Therefore, current methods for sterilizing clothing typically include ultraviolet (UV) irradiation, ozone, and silver ions. However, UV irradiation sterilization usually only works on the surface of the clothing exposed to UV light, and the limited space inside the drum makes it difficult to achieve UV coverage of all clothing surfaces. Ozone sterilization is effective, but ozone is harmful to humans; the National Indoor Air Quality Standards strictly limit ozone levels. Furthermore, ozone's strong oxidizing properties can easily cause clothing to fade, hindering its widespread adoption. Silver ion sterilization involves adding nanomaterials to the surfaces of the washing machine's inner and outer drums, releasing bactericidal silver ions during washing. However, silver ion sterilization requires the clothing to be in full contact with the silver ions to be effective; areas not in contact will not be sterilized.

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

[0005] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem that the sterilization method of washing machines in the prior art is not effective.

[0006] This invention provides a control method for a garment processing device. The garment processing device includes a housing, an outer cylinder disposed within the housing, and an inner cylinder disposed within the outer cylinder. The inner cylinder is connected to the outer cylinder and is rotatable relative to the outer cylinder. The garment processing device is equipped with a photo-plasma fresh air device. The photo-plasma fresh air device includes a housing, a photo-plasma tube, and a fan disposed within the housing. The housing has an air inlet and an air outlet. The air inlet is connected to the environment, and the air outlet is connected to the inner cylinder. A connection is established between the air inlet and the air outlet. An air duct is formed, at least a portion of the photoplasma tube is located within the air duct, the photoplasma tube is configured to ionize air when energized to generate a gas containing ionized substances, the fan is configured to introduce ambient air into the housing through the air inlet and expel the gas ionized by the photoplasma tube through the air outlet, the control method includes: acquiring the washing mode of the garment processing equipment; determining whether the washing mode is a quick wash mode; if the washing mode is a quick wash mode, controlling the photoplasma tube and the fan to operate.

[0007] In a preferred embodiment of the above control method, the control method further includes: obtaining the odor concentration inside the inner cylinder before controlling the operation of the photoplasma tube and the fan; comparing the odor concentration with a concentration threshold; and selectively controlling the operation of the photoplasma tube and the fan based on the first comparison result.

[0008] In the preferred embodiment of the above control method, the photo-plasma fresh air device is disposed below the outer cylinder, and a waterproof and breathable valve is provided between the photo-plasma fresh air device and the outer cylinder. The step of "selectively controlling the operation of the photo-plasma tube and the fan according to the first comparison result" further includes: if the odor concentration is greater than the concentration threshold, then obtaining the operating stage of the quick wash mode; determining whether the operating stage is the spin-drying stage; and selectively controlling the operation of the waterproof and breathable valve, the photo-plasma tube, and the fan according to the determination result.

[0009] In the preferred embodiment of the above control method, the step of "selectively controlling the operation of the waterproof and breathable valve, the photoplasma tube, and the fan according to the judgment result" further includes: if the operation stage is the spin-drying stage, then controlling the waterproof and breathable valve to open; while controlling the opening of the waterproof and breathable valve, or after controlling the opening of the photoplasma tube and the fan to operate.

[0010] In the preferred embodiment of the above control method, both the photoplasma tube and the fan have high, medium and low speeds. The step of "controlling the operation of the photoplasma tube and the fan" further includes: controlling both the photoplasma tube and the fan to operate at high speed.

[0011] In a preferred embodiment of the above control method, the control method further includes: after controlling the photoplasma tube and the fan to run for a preset time, controlling the photoplasma tube and the fan to stop running.

[0012] In a preferred embodiment of the above control method, the control method further includes: obtaining the running time of the spin-drying stage before controlling the opening of the waterproof and breathable valve; comparing the running time with a time threshold; and selectively controlling the opening of the waterproof and breathable valve based on a second comparison result.

[0013] In the preferred embodiment of the above control method, the step of "selectively controlling the opening of the waterproof and breathable valve based on the second comparison result" specifically includes: if the running time is greater than the time threshold, then the waterproof and breathable valve is controlled to open; if the running time is less than or equal to the time threshold, then the waterproof and breathable valve is not controlled to open.

[0014] In the preferred embodiment of the above control method, the step of "selectively controlling the operation of the photoplasma tube and the fan according to the judgment result" further includes: if the operation stage is not the spin-drying stage, then the waterproof and breathable valve is not controlled to open, and the operation of the photoplasma tube and the fan is not controlled.

[0015] In the preferred embodiment of the above control method, the photo-plasma fresh air device is disposed above the outer cylinder, and both the photo-plasma tube and the fan have high, medium and low speeds. The step of "selectively controlling the operation of the photo-plasma tube and the fan according to the first comparison result" further includes: if the odor concentration is greater than the concentration threshold, then the photo-plasma tube and the fan are controlled to operate at medium speed until the quick wash mode operation ends.

[0016] In the technical solution of this invention, the garment processing equipment includes a housing, an outer cylinder disposed within the housing, and an inner cylinder disposed within the outer cylinder. The inner cylinder is connected to the outer cylinder and is configured to rotate relative to the outer cylinder. The garment processing equipment is equipped with a photo-plasma fresh air device, which includes a housing, a photo-plasma tube disposed within the housing, and a fan. The housing has an air inlet and an air outlet. The air inlet is connected to the environment, and the air outlet is connected to the inner cylinder. An air duct is formed between the air inlet and the air outlet. At least a portion of the photo-plasma tube is located within the air duct. The fan is disposed within the housing. The photo-plasma tube is configured to ionize air when energized, thereby generating a gas containing ionized substances. The fan is configured to introduce air from the environment into the housing through the air inlet and expel the gas ionized by the photo-plasma tube through the air outlet. With this setup, ambient air enters the housing through the air inlet under the action of the fan. When energized, the photoplasma tube inside the housing decomposes pure oxygen and water in the air into ionic substances such as hydroxide ions, free oxygen atoms, and superoxide ions. The gas containing these ionic substances then enters the inner drum through the air outlet. Since these ionic substances effectively remove bacteria and viruses, they can also disinfect bacteria and viruses inside the inner drum and on the clothing being treated. In other words, this application's photoplasma fresh air device can effectively remove bacteria and viruses from the inner drum and the clothing being treated, achieving a good sterilization effect. Simultaneously, the gas introduced into the inner drum by the fan also promotes the expulsion of existing air, thereby enhancing airflow within the inner drum, achieving the purpose of deodorizing, preventing mold and bacterial growth, and effectively improving the user experience.

[0017] The control method of this invention includes: acquiring the washing mode of the garment processing equipment, determining whether the washing mode is a quick wash mode, and if the washing mode is a quick wash mode, controlling the operation of the photo-plasma tube and the fan. Through this control method, the operation of the photo-plasma tube and the fan is controlled when the washing mode is a quick wash mode. This combines the operation of the photo-plasma tube and the fan with the quick wash mode, ensuring that the washing of clothes is completed quickly to meet user needs, while also better disinfecting the outer drum, inner drum, and clothes located inside the inner drum, achieving a better sterilization effect.

[0018] Furthermore, before controlling the operation of the photoplasma tube and fan, the odor concentration inside the inner cylinder is obtained, and this odor concentration is compared with a concentration threshold. Based on the first comparison result, the operation of the photoplasma tube and fan is selectively controlled. Through this control method, the operation of the photoplasma tube and fan is controlled according to the odor concentration inside the inner cylinder. This allows for control of the operation of the photoplasma tube and fan based on the specific conditions inside the inner cylinder, thereby saving energy while ensuring sterilization effectiveness.

[0019] Furthermore, the photo-plasma fresh air device is located below the outer drum, and a waterproof vent valve is installed between the photo-plasma fresh air device and the outer drum. This waterproof vent valve allows the photo-plasma fresh air device to be connected or disconnected from the outer drum. In this case, if the odor concentration exceeds the concentration threshold, it indicates that there is already an odor in the inner drum, which may contain a large number of bacteria, viruses, etc. At this time, the operating stage of the quick wash mode is obtained to determine whether the operating stage is the spin-drying stage. Based on the determination result, the operation of the waterproof vent valve, photo-plasma tube, and fan is selectively controlled. Since the photo-plasma fresh air device is located below the outer drum, if the quick wash mode is in the washing or rinsing stage, where there is washing water in the outer drum, the washing water may enter the photo-plasma fresh air device, potentially damaging it. Therefore, it is necessary to determine the current operating stage of the quick wash mode and whether it is the spin-drying stage. Based on this determination, the operation of the waterproof vent valve, photo-plasma tube, and fan can be selectively controlled. This ensures effective sterilization while preventing damage to the photo-plasma fresh air device caused by operating it while there is washing water in the outer drum, thus effectively improving the user experience.

[0020] If the operation is in the spin-drying phase, the waterproof and breathable valve is opened. Simultaneously or after opening the valve, the photoplasma tube and fan are operated. In other words, during the spin-drying phase, the waterproof and breathable valve is opened, and the photoplasma tube and fan are operated. Since the outer and inner drums are connected, the inner drum is also connected to the photoplasma fresh air device. Under the action of the fan, ambient air is introduced into the casing, ionized by the photoplasma tube to produce gas containing ionized substances, and then sent into the inner drum. This disinfects the outer drum, inner drum, and the clothes inside the inner drum, achieving a better sterilization effect.

[0021] Furthermore, after controlling the photoplasma tube and fan to run for a preset time, at this point, the photoplasma tube and fan have been running for a relatively long time and have introduced a large amount of gas containing ionized substances into the inner drum. Bacteria and viruses on the outer drum, inner drum, and clothing have been basically eliminated. At this point, the photoplasma tube and fan are stopped. This achieves a good sterilization effect while saving energy.

[0022] Furthermore, before controlling the opening of the waterproof vent valve, the duration of the spin-drying phase is obtained and compared with a time threshold. If the duration exceeds the threshold, there is essentially no washing water remaining in the outer drum. In this case, the waterproof vent valve is opened, preventing washing water from entering the housing and ensuring stable operation of the photo-plasma fresh air system for better sterilization. If the duration is less than or equal to the threshold, a small amount of washing water may still remain in the outer drum. In this case, the waterproof vent valve is not opened to prevent washing water from entering the housing and damaging the photo-plasma fresh air system. This control method achieves good sterilization while avoiding damage to the photo-plasma fresh air system.

[0023] If the operation is not in the spin-drying stage, then the current quick wash mode means there is still washing water in the outer drum. If the waterproof vent valve is opened at this time, washing water may enter the photo-plasma fresh air unit, potentially damaging it. Therefore, in this situation, the waterproof vent valve should not be opened, and the photo-plasma tube and fan should not be controlled to ensure the safety of the photo-plasma fresh air unit.

[0024] Furthermore, the photo-plasma fresh air device is located above the outer drum, and both the photo-plasma tube and fan have high, medium, and low speed settings. In this case, if the odor concentration exceeds the concentration threshold, it indicates that there is already an odor inside the inner drum, possibly containing a large number of bacteria and viruses. At this time, the photo-plasma tube and fan are controlled to operate at the medium speed until the quick wash cycle ends. Through this control method, the photo-plasma tube and fan can operate throughout the entire washing process, thereby better disinfecting the outer drum, inner drum, and clothes, achieving a better sterilization effect.

[0037] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the invention and are not intended to limit the scope of protection of the invention. Although this application uses a drum washing machine with a photo-plasma fresh air device as an example, it is obviously also applicable to other types of clothing handling equipment such as pulsator washing machines and washer-dryer combos.

[0038] It should be noted that in the description of this invention, the terms "upper," "lower," "left," "right," "inner," and "outer," etc., indicating directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, it should be noted that in the description of this application, unless otherwise explicitly specified and limited, the terms "connected" and "connected" 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; and they can refer to the internal communication between two elements. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0039] To remove bacteria and viruses from clothing, drum washing machines typically use methods such as ultraviolet (UV) irradiation, ozone, and silver ions for sterilization. However, UV irradiation sterilization usually only sterilizes clothing exposed to UV light, resulting in limited effectiveness. Ozone sterilization is more effective, but ozone is harmful to humans. Silver ion sterilization requires contact with clothing to achieve sterilization, thus its effectiveness is also limited. Therefore, this invention provides a control method for a clothing treatment device. By adjusting the frequency of the photoplasma tube and the fan speed according to the washing mode, the device can better disinfect the inner drum and the clothing inside, achieving a better sterilization effect.

[0040] First, refer to Figures 1 to 4 The possible implementations of the clothing management device of the present invention will be described.

[0041] like Figures 1 to 4 As shown, a drum washing machine includes a casing 1, an inner drum 2 disposed within the casing 1, and an outer drum 3 disposed outside the inner drum 2. The inner drum 2 is rotatable relative to the outer drum 3. Clothes to be washed are placed into the inner drum 2, and the drum washing machine is started to wash the clothes. It should be noted that a drum washing machine may also not include the outer drum 3.

[0042] The photo-plasma fresh air device 4 includes a housing 41, a photo-plasma tube 42, and a fan 43. The photo-plasma tube 42 is configured as a U-shaped tube, and the fan 43 is an axial flow fan. Both the photo-plasma tube 42 and the fan 43 are housed inside the housing 41, which isolates them from the external environment. This prevents dust from accumulating on the photo-plasma tube 42 and the fan 43, affecting their air ionization efficiency, and prevents moisture from causing the photo-plasma tube 42 and the fan 43 to become damp or even short-circuit, thus ensuring the stable operation of the photo-plasma fresh air device 4. The housing 41 has a roughly rectangular cross-section and has an air inlet 411 and an air outlet 412. The air inlet 411 is connected to the environment. An air outlet duct 4121 is provided at the air outlet 412, with one end connected to the air outlet 412 and the other end connected to the outer cylinder 3, thus achieving interconnection between the air outlet 412 and the outer cylinder 3. The inner cylinder 2 is provided with multiple water passage holes, meaning that the outer cylinder 3 and the inner cylinder 2 are connected, thus enabling the air outlet 412 to be connected to the inner cylinder 2. An air duct is formed between the air inlet 411 and the air outlet 412. At least a portion of the photoplasma tube 42 is located within the air duct. The photoplasma tube 42 is configured to ionize air when energized, thereby generating a gas containing ionized substances. The fan 43 is configured to introduce ambient air into the housing 41 through the air inlet 411 and send the gas ionized by the photoplasma tube 42 out through the air outlet 412.

[0043] With this configuration, under the action of fan 43, ambient air enters the housing 41 through air inlet 411. When energized, the photoplasma tube 42 inside the housing 41 decomposes pure oxygen and water in the air into hydroxyl, free oxygen atoms, and superoxide ions, forming ionic substances. The gas containing these ionic substances then enters the inner drum 2 through air outlet 412. These ionic substances can decompose volatile organic compounds and other harmful substances into carbon dioxide and water, and can also destroy bacterial cell membranes, thus achieving antibacterial effects. In this way, the ionic substances in the gas can disinfect bacteria and viruses in the outer drum 3, inner drum 2, and on the laundry inside. In other words, this application's photoplasma fresh air device 4 can effectively remove bacteria and viruses from the outer drum 3, inner drum 2, and the laundry inside, achieving a good sterilization effect. Simultaneously, the gas introduced into the inner cylinder 2 by the fan also causes the original air inside the inner cylinder 2 to be expelled, thereby enhancing the airflow inside the inner cylinder and achieving the purpose of deodorizing, preventing the growth of mold and bacteria, thus effectively improving the user experience. Obviously, the cross-section of the shell 41 can also be set to other possible shapes such as ellipse, square, hexagon.

[0044] It should be noted that the photoplasma tube 42 can also be configured as a strip tube, a W-shaped tube, or other possible forms. Without departing from the principle of this application, those skilled in the art can flexibly choose the specific configuration of the photoplasma tube 42 according to the specific application scenario, as long as the photoplasma tube 42 can ionize the air to generate a gas containing ionized substances when energized.

[0045] It should be noted that the fan 43 can also be a cross-flow fan, a centrifugal fan or other possible types. Without departing from the principle of this application, those skilled in the art can flexibly choose the specific type of fan 43 according to the specific application scenario, as long as the fan 43 can introduce air from the environment into the housing 41 through the air inlet 411 and send the gas ionized by the photoplasma tube 42 out through the air outlet 412.

[0046] It should be noted that the air inlet 411 can be directly connected to the space between the outer drum 3 and the outer shell 1. When the photo-plasma fresh air device 4 is running, the air in the space between the outer drum 3 and the outer shell 1 enters the shell 41 through the air inlet 411, is ionized by the photo-plasma tube 42, and then enters the inner drum 2. Alternatively, an air inlet pipe can be provided at the air inlet 411. In this case, a vent is provided on the outer shell 1, and the end of the air inlet pipe away from the shell 41 is connected to the vent on the outer shell 1, thus enabling the air inlet 411 to communicate with the environment. Obviously, when a circulating air duct is provided inside the drum washing machine, the end of the air inlet pipe away from the shell 41 can also be connected to the circulating air duct. Without departing from the principles of this application, those skilled in the art can flexibly choose the specific arrangement of the air inlet 411 communicating with the environment, as long as air from the environment can enter the shell 41 through the air inlet 411.

[0047] In one possible implementation, the photoplasma tube 42 of this application can emit ultraviolet light with a wavelength of 170-190nm when energized. Under the action of ultraviolet light of this wavelength, it can ionize the air to produce more ionized substances. Thus, the gas containing ionized substances obtained after ionization by the photoplasma tube 42 can remove more bacteria, viruses, etc., thereby achieving a better sterilization effect.

[0048] Obviously, the photoplasma tube 42 can also emit ultraviolet light of other wavelengths when it is powered on. Compared with ultraviolet light with wavelengths of 170-190nm, the amount of ionized substances produced by ionizing the air is reduced when the photoplasma tube 42 emits ultraviolet light of other wavelengths, but a certain sterilization effect can still be achieved.

[0049] like Figure 1 As shown, the air inlet 411 and the air outlet 412 are respectively located on opposite sides of the housing 41 (i.e., Figure 1(As shown in the diagram, the housing 41 has left and right sides). Under the action of the fan 43, ambient air enters the housing 41 through the right-side air inlet 411 and is then discharged from the left-side air outlet 412. Inside the housing 41, near the air inlet 411, a mounting base 44 is provided. The photoplasma tube 42 and the fan 43 are respectively mounted on this mounting base 44 along the airflow direction (i.e.,...). Figure 1 The photoplasma tube 42 extends along the direction of airflow (i.e., along the left and right sides of the tube). When assembled, the photoplasma tube 42 extends along the direction of airflow (i.e., along the left and right sides of the tube). Figure 1 Extending left and right in the middle, the fan 43 is aligned with the air inlet 411, thus positioning the fan 43 upstream of the photoplasma tube 42 along the airflow direction and close to the air inlet 411. Under the action of the fan 43, ambient air enters the housing 41 through the air inlet 411 and is blown towards the photoplasma tube 42 by the fan 43. This ensures that the air can come into contact with the photoplasma tube 42 throughout its entire flow path within the housing 41, allowing for more thorough contact and ionization to generate more ionized substances, thereby achieving a better sterilization effect.

[0050] It should be noted that the air inlet 411 and air outlet 412 can also be arranged on the housing 41 in other ways. Specifically, as shown below... Figure 2 As shown, according to Figure 2 As shown, the air inlet 411 is located on the right side of the housing 41, and the air outlet 412 is located on the upper side of the housing 41, meaning the air inlet 411 and air outlet 412 are respectively located on adjacent sides of the housing 41. The air outlet 412 is located near the end of the photoplasma tube 42 furthest from the mounting base 44. Thus, after ambient air enters the housing 41 through the air inlet 411 on the right side, it is blown towards the photoplasma tube 42 by the fan 43, comes into contact with and is ionized by the photoplasma tube 42, and is then discharged through the upper air outlet 412. This forms a roughly L-shaped airflow channel within the housing 41. Because the air outlet 412 is located near the left side of the housing 41, it can also promptly discharge gases containing ionized substances from the housing 41. Alternatively, the air inlet 411 could be located on the right side of the housing 41, and the air outlet on the lower side of the housing 41, etc. Without departing from the principles of this application, those skilled in the art can flexibly choose the specific placement of the air inlet 411 and the air outlet 412 on the housing 41 according to the specific application scenario, as long as the air in the environment can enter the housing 41 through the air inlet 411 and the ionized air can be discharged through the air outlet 412.

[0051] like Figure 1 and Figure 3As shown, the photo-plasma fresh air device 4 also includes a waterproof and breathable component, which is a waterproof and breathable membrane 45. This membrane 45 is configured to allow only gas to pass through. In this application, the waterproof and breathable membrane 45 can be installed at the air outlet 412 by means of bonding, screwing, or snapping. The waterproof and breathable membrane 45 is a novel polymer waterproof material, mainly composed of three layers: PP spunbond nonwoven fabric, PE polymer breathable membrane, and PP spunbond nonwoven fabric. The waterproof and breathable membrane 45 achieves the purpose of preventing water from passing through through the following principle: In the state of water vapor, water particles are very small. According to the principle of capillary motion, they can easily penetrate into the capillary to the other side, thus causing vapor permeation. When water vapor condenses into water droplets, the particles become larger. Due to the surface tension of the water droplets (the mutual "pulling and resistance" between water molecules), the water molecules cannot easily detach from the water droplets and penetrate to the other side, thus preventing water penetration and giving the breathable membrane a waterproof function.

[0052] In this way, when the photo-plasma fresh air device 4 is running, ambient air enters the housing 41 through the air inlet 411, is ionized by the photo-plasma tube 42, then passes through the waterproof and breathable membrane 45, and finally enters the inner drum 2 through the air outlet 4121. Even if the drum washing machine is in the process of washing and a lot of washing water splashes up, the waterproof and breathable membrane 45 will prevent the washing water in the outer drum 3 from entering the housing 41 through the air outlet 412, thus ensuring the stable operation of the photo-plasma fresh air device 4.

[0053] It should be noted that the waterproof and breathable component can also be valve 46, for example, valve 46 can be a solenoid valve, etc. Specifically, as shown below... Figure 2 and Figure 4 As shown, valve 46 is installed on the air outlet pipe 4121. When the photo-plasma fresh air device 4 is running, valve 46 is opened; when the photo-plasma fresh air device 4 is not running, valve 46 is closed. This also prevents washing water from entering the housing 41, ensuring the stable operation of the photo-plasma fresh air device 4. Of course, when the waterproof and breathable component is valve 46, the air outlet 412 may not require an air outlet pipe 4121; the valve 46 can be directly snapped onto the air outlet 412. In this case, valve 46 can be a threaded waterproof and breathable valve, a snap-on waterproof and breathable valve, a twist-lock waterproof and breathable valve, a plug-type waterproof and breathable valve, or other possible types. Without departing from the principles of this application, those skilled in the art can flexibly choose the specific configuration of the waterproof and breathable component according to the specific application scenario, as long as it only allows gas to pass through.

[0054] It is understandable that the photo-plasma fresh air device 4 may not include waterproof and breathable components. In this case, in order to avoid the washing water from affecting the photo-plasma fresh air device 4, the photo-plasma fresh air device 4 can be set on the top side or near the top side of the outer wall of the outer cylinder 3 or at other positions higher than the washing water level.

[0055] like Figure 1 and Figure 2 As shown, the photo-plasma fresh air device 4 also includes a control module 47, which can selectively control the operation of the photo-plasma tube 42 and the fan 43 according to the odor concentration in the inner cylinder 2, and can also selectively control the operation of the photo-plasma tube 42 and the fan 43 according to the operating stage of the quick wash mode.

[0056] It should be noted that the photo-plasma fresh air device 4 may not require a separate control module, but can achieve the above control functions through the control chip of the drum washing machine itself, or a functional module or functional unit of a general controller.

[0057] It should be noted that when the waterproof and breathable component is valve 46, in this case, valve 46 is connected to control module 47, and control module 47 is configured to control the opening and closing of valve 46.

[0058] The following reference Figure 3 and Figure 4 This paper describes a possible implementation of the photo-plasma fresh air device 4 of this application on a drum washing machine.

[0059] like Figure 3 and Figure 4 As shown, a through hole (not shown) is provided on the upper side of the outer drum 3. One end of the air outlet pipe 4121 is connected to the air outlet 412 of the photo-plasma fresh air device 4, and the other end is connected to the through hole, thus placing the photo-plasma fresh air device 4 above the outer drum 3. When the drum washing machine is running, the photo-plasma fresh air device 4 is turned on. The gas containing ionized substances generated by the photo-plasma fresh air device 4 enters the outer drum 3 through the air outlet 412 and then enters the inner drum 2, sterilizing the drum washing machine and the clothes to be washed in the inner drum 2, and causing the original air in the inner drum 2 to be expelled, thereby achieving a better sterilization and deodorization effect.

[0060] It should be noted that the photo-plasma fresh air device 4 can also be located below the outer drum 3. In this case, to prevent washing water in the outer drum 3 from entering the housing 41, the waterproof and breathable component is set as a valve 46. When the drum washing machine is running and there is water in the outer drum 3, the valve 46 is closed. When the drum washing machine is not running or there is no water in the outer drum 3, the valve 46 can be opened, and the photo-plasma fresh air device 4 can be used to sterilize and deodorize the drum washing machine. Of course, the photo-plasma fresh air device 4 can also be located near or below the outer drum 3. Without departing from the principle of this application, those skilled in the art can flexibly choose the specific placement of the photo-plasma fresh air device 4 inside the housing 1 according to the specific application scenario, as long as it can sterilize the drum washing machine.

[0061] The drum washing machine includes a control panel (not shown), which has indicator lights that are configured to display the operating status of the photo-plasma fresh air device 4. Specifically, a yellow indicator light indicates that the photo-plasma fresh air device 4 is in normal operation, a green indicator light indicates that the photo-plasma fresh air device 4 has completed its operation, and a red indicator light indicates that the photo-plasma fresh air device 4 is in an abnormal operating state.

[0062] It should be noted that the different colored indicator lights indicating the operating status of the photoplasma fresh air device 4 are merely illustrative examples. They can obviously represent other operating states as well. For instance, a red indicator light indicates that the photoplasma fresh air device 4 is in normal operation; a green indicator light indicates that the photoplasma fresh air device 4 has completed operation; and a yellow indicator light indicates that the photoplasma fresh air device 4 is in an abnormal operating state. Without departing from the principles of this application, those skilled in the art can flexibly choose the specific implementation method for the indicator lights to display the operating status of the photoplasma fresh air device 4 according to the specific application scenario, as long as the operating status of the photoplasma fresh air device 4 can be displayed through the indicator lights.

[0063] In this application, the drum washing machine is equipped with an odor detection module, which is located inside the inner drum and is configured to detect the odor concentration inside the drum. For example, the odor detection module can be an odor sensor, which is an odor recognizer based on the principle of MEMS (Microelectro Mechanical Systems), and has advantages such as high recognition accuracy and fast speed.

[0064] Obviously, the odor detection module can also be an olfactory cell chip, which includes a cell membrane, a gas-sensitive sensor array, a processor, and a signal transmitter. The cell membrane covers the gas-sensitive sensor array and is used to filter odor molecules. The gas-sensitive sensor array detects the filtered odor molecules and generates an electrical signal. The processor is connected to the gas-sensitive sensor array and processes the electrical signal generated by the array. The signal transmitter is connected to the processor and transmits the processed electrical signal. Those skilled in the art can flexibly choose the specific configuration of the odor detection module according to the specific application scenario, as long as the odor detection module can detect the odor concentration inside the inner cylinder.

[0065] In this application, both the photoplasma tube and the fan have high, medium, and low speed settings. That is, the photoplasma tube can operate at high, medium, and low frequencies respectively. The frequency of the photoplasma tube is related to the amount of ionized matter it can ionize; the higher the frequency, the more ionized matter it can generate. The fan can operate at high, medium, and low speeds respectively; the higher the fan speed, the greater the airflow. Obviously, the photoplasma tube and fan can also have four or five speed settings, or even two or one, allowing those skilled in the art to choose flexibly according to specific application scenarios.

[0066] In this application, the quick wash mode generally includes a washing stage, a rinsing stage, and a spin-drying stage. During the washing and rinsing stages, a significant amount of washing water typically remains in the outer drum. Since the photo-plasma fresh air device is located below the outer drum, operating the device while washing water is present in the outer drum could potentially cause washing water to enter and damage the device.

[0067] The following reference Figures 5 to 9 This paper describes possible implementations of the control method for the drum washing machine of the present invention.

[0068] like Figure 5 As shown, in one possible implementation, the control method of the present invention includes:

[0069] S100: Obtain the washing mode of the drum washing machine;

[0070] S101: Determine whether the washing mode is a quick wash mode;

[0071] S102: If the washing mode is quick wash mode, control the operation of the photo-plasma tube and fan.

[0072] In S100, the washing mode of the drum washing machine is obtained.

[0073] It should be noted that the washing mode of this drum washing machine can be preset by the user through the remote control, the control panel on the drum washing machine, or the APP that communicates with the drum washing machine, or the drum washing machine can be automatically determined by the drum washing machine based on factors such as the type of clothes, the amount of clothes, and the current season.

[0074] In S101, based on the washing mode of the drum washing machine obtained in S100, it is determined whether the washing mode is a quick wash mode.

[0075] In S102, based on the judgment result in S101, when it is determined that the washing mode is quick wash mode, the photo-plasma tube and fan are controlled to run.

[0076] Through the above control method, when the washing mode is quick wash mode, the operation of the photo-plasma tube and the fan is controlled. This combines the operation of the photo-plasma tube and the fan with the quick wash mode, ensuring that the washing of clothes is completed quickly to meet the user's needs, while also better disinfecting the outer drum, inner drum, and clothes inside the inner drum, achieving a better sterilization effect.

[0077] like Figure 6 As shown, in one possible implementation, the control method of the present invention further includes:

[0078] S200: Obtain the odor concentration inside the inner cylinder before controlling the operation of the photoplasma and fan;

[0079] S201: Compare the odor concentration with the concentration threshold;

[0080] S202: Based on the first comparison result, selectively control the operation of the photoplasma tube and the fan.

[0081] In S200, before controlling the operation of the photoplasma and the fan, that is, before executing S102, the odor concentration inside the inner cylinder is detected by the aforementioned odor detection module.

[0082] In S201, based on the odor concentration obtained in S200, the odor concentration is compared with the concentration threshold.

[0083] In S202, based on the first comparison result in S201, the operation of the photoplasma tube and the fan is selectively controlled.

[0084] This control method adjusts the operation of the photoplasma tube and fan based on the odor concentration inside the inner cylinder. This allows for precise control of the photoplasma tube and fan operation according to the specific conditions inside the inner cylinder, thus ensuring sterilization effectiveness while saving energy.

[0085] It should be noted that the odor concentration inside the drum can be omitted before controlling the operation of the photo-plasma tube and fan; that is, S200 can be omitted before S102. Instead, the photo-plasma tube and fan can be directly controlled to operate after the washing mode is determined to be quick wash mode.

[0086] In one possible implementation, the photo-plasma fresh air device is located below the outer cylinder, and a waterproof and breathable valve is provided between the photo-plasma fresh air device and the outer cylinder, which allows the photo-plasma fresh air device to be connected to or disconnected from the outer cylinder.

[0087] The following reference Figure 7 and Figure 8 This invention describes possible implementations of the control method when the photo-plasma fresh air device is located below the outer cylinder and a waterproof and breathable valve is provided between the photo-plasma fresh air device and the outer cylinder.

[0088] like Figure 7 As shown, in one possible implementation, the control method of the present invention further includes:

[0089] S300: Obtain the odor concentration inside the inner cylinder before controlling the operation of the photoplasma and fan;

[0090] S301: Determine whether the concentration of the odor is greater than the concentration threshold. If yes, proceed to S303; otherwise, proceed to S302.

[0091] S302: Does not control the operation of the photoplasma tube and fan;

[0092] S303: Obtain the current operating stage of the quick wash mode;

[0093] S304: Determine whether the operation phase is the spin-drying phase. If yes, proceed to S306; otherwise, proceed to S305.

[0094] S305: Do not open the waterproof vent valve, and do not control the operation of the photoplasma tube and fan;

[0095] S306: Controls the opening of the waterproof and breathable valve;

[0096] S307: Controls the operation of the photoplasma tube and fan.

[0097] In S300, similar to S200, before controlling the operation of the photoplasma and fan, that is, before executing S102, the odor concentration inside the inner cylinder is detected by the aforementioned odor detection module.

[0098] In S301, based on the odor concentration obtained in S300, it is determined whether the odor concentration is greater than the concentration threshold. If the odor concentration is less than or equal to the concentration threshold, it means that there is basically no odor in the inner cylinder and the content of bacteria, viruses and other substances in the inner cylinder is low, so there is no need to carry out disinfection treatment. At this time, the operation of the photoplasma tube and the fan is not controlled, that is, S302 is executed.

[0099] If the odor concentration is greater than the concentration threshold, it indicates that there is already an odor in the inner drum, which may contain a lot of bacteria, viruses, etc., and disinfection is required. At this time, the operating stage of the quick wash mode is obtained, that is, S303 is executed.

[0100] In S304, based on the operating stage obtained in S303, it is determined whether the operating stage is the spin-drying stage. If it is not the spin-drying stage, it means that the quick wash mode may be in the washing or rinsing stage. In this case, there is washing water in the outer drum. At this time, the waterproof vent valve is not opened, and the operation of the photo-plasma tube and fan is not controlled. That is, S305 is executed to avoid damaging the photo-plasma fresh air device.

[0101] If it is the spin-drying stage, it means that there is basically no washing water in the outer drum. At this time, the waterproof and breathable valve is opened, that is, S306 is executed to connect the photo-plasma fresh air device to the inner drum.

[0102] After the waterproof and breathable valve is opened, the photoplasma tube and fan are controlled to operate, i.e., after executing S306, S307 is executed. This connects the inner drum with the photoplasma fresh air device. Under the action of the fan, ambient air is introduced into the housing, ionized by the photoplasma tube to generate gas containing ionized substances, and then sent into the inner drum through the trigger port to disinfect the outer drum, inner drum, and clothes inside the inner drum, thereby achieving a better sterilization effect.

[0103] It should be noted that the operation of the photoplasma tube and fan can also be controlled at the same time as the opening of the waterproof and breathable valve. Without deviating from the principle of this application, those skilled in the art can flexibly choose the specific timing of controlling the operation of the photoplasma tube and fan according to the specific application scenario, as long as a good sterilization effect can be obtained.

[0104] In summary, when the photo-plasma fresh air unit is located below the outer cylinder and a waterproof vent valve is installed between the unit and the outer cylinder, if the odor concentration inside the inner cylinder is less than or equal to the concentration threshold, the photo-plasma tube and fan will not be controlled to operate. If the odor concentration inside the cylinder is greater than the concentration threshold, it will further determine whether the quick wash mode is in the spin-drying stage. If the quick wash mode is not in the spin-drying stage, the photo-plasma tube and fan will not be controlled to operate. If the quick wash mode is in the spin-drying stage, the waterproof vent valve will be opened, and the photo-plasma tube and fan will be controlled to operate. Through this control method, while ensuring a good sterilization effect, damage to the photo-plasma fresh air unit can be avoided, thus improving the user experience.

[0105] In one possible implementation, controlling the operation of the photoplasma tube and fan in S307 specifically includes controlling both the photoplasma tube and the fan to operate at high speeds, i.e., controlling the photoplasma tube to operate at a high frequency and the fan to operate at a high speed, for example, controlling the photoplasma tube to operate at a frequency of 8W and the fan to operate at a speed of 860r / min. Through this control method, the photoplasma tube can ionize the air to generate more ionized substances, and the fan can quickly introduce more air from the environment into the housing and send more gas containing ionized substances into the inner cylinder, thus achieving a better sterilization effect quickly in a shorter time. Obviously, S307 could also specifically control both the photoplasma tube and the fan to operate at medium or low speeds, but the sterilization effect of this control method would be weakened.

[0106] In one possible implementation, after the photoplasma tube and fan have been running for a preset time, for example, after 15 minutes, the photoplasma tube and fan have been running for a relatively long time and have introduced a large amount of gas containing ionized substances into the inner drum. Bacteria and viruses on the outer drum, inner drum, and clothing have been basically eliminated. At this point, the photoplasma tube and fan are stopped. This ensures the sterilization effect while saving energy.

[0107] like Figure 8 As shown, in one possible implementation, the control method of the present invention further includes:

[0108] S400: Obtain the runtime of the spin-drying phase before controlling the opening of the waterproof and breathable valve;

[0109] S401: Determine whether the runtime is greater than the runtime threshold. If yes, execute S402; otherwise, execute S403.

[0110] S402: Controls the opening of the waterproof and breathable valve;

[0111] S403: Do not control the opening of the waterproof and breathable valve.

[0112] In S400, the runtime of the spin-drying stage is obtained before the control of the waterproof and breathable valve is opened, i.e. before S306 is executed.

[0113] In S401, based on the runtime obtained in S400, it is determined whether the runtime exceeds a time threshold. If the runtime exceeds the time threshold (e.g., the spin-drying stage lasts 5 minutes, and the time threshold is 1 minute), it means that the spin-drying stage has been running for some time and most of the water remaining on the clothes has been spun out and drained. Essentially, no more water will be spun out, meaning there will be no more washing water in the outer drum. At this point, the waterproof vent valve is opened, i.e., S402 is executed. Opening the waterproof vent valve at this time prevents water from entering the photo-plasma fresh air device, thus preventing damage to it.

[0114] If the running time is less than or equal to the time threshold, for example, the spin-drying stage lasts for 10 seconds and the time threshold is 1 minute, it means that the spin-drying stage has just started. There is still some water remaining on the clothes, and more water will be spun out. There will still be a small amount of washing water inside the outer drum. At this time, the waterproof vent valve will not be opened, i.e., S403 will be executed to prevent the washing water inside the outer drum from entering the photo-plasma fresh air device and causing it to be damaged.

[0115] By using the above control methods, a good sterilization effect can be achieved without damaging the photo-plasma fresh air device.

[0116] It should be noted that the duration of the spin-drying phase can be omitted before controlling the opening of the waterproof vent valve. That is, S400 is not executed before S306; instead, the waterproof vent valve is directly opened after determining that the current operating phase is the spin-drying phase. Specifically, if the determination result in S304 is "yes," S306 is executed directly. In this case, to prevent the washing water in the outer drum from damaging the photo-plasma fresh air device, the connection between the photo-plasma fresh air device and the outer drum can be located on the upper side of the lowest point of the outer drum. This way, even if there is a small amount of washing water in the outer drum, it will not enter the photo-plasma fresh air device.

[0117] In one possible implementation, the photo-plasma fresh air device is positioned above the outer casing. Based on this, see below for further details. Figure 9 This paper describes possible implementations of the control method of the present invention when the photo-plasma fresh air device is installed above the outer cylinder.

[0118] like Figure 9 As shown, in one possible implementation, the control method of the present invention further includes:

[0119] S500: Obtain the odor concentration inside the inner cylinder before controlling the operation of the photoplasma and fan;

[0120] S501: Determine whether the concentration of the odor is greater than the concentration threshold. If yes, execute 5303; otherwise, execute S502.

[0121] S502: Does not control the operation of the photoplasma tube and fan;

[0122] S503: Controls the photo-plasma tube and fan to run at medium speed until the quick wash mode ends.

[0123] In S500, similar to S200 and S300, before controlling the operation of the photoplasma and fan, that is, before executing S102, the odor concentration inside the inner cylinder is detected by the aforementioned odor detection module.

[0124] In S501, based on the odor concentration obtained in S500, it is determined whether the odor concentration is greater than the concentration threshold. If the odor concentration is less than or equal to the concentration threshold, it means that there is basically no odor generated in the inner cylinder and no disinfection treatment is required. At this time, the operation of the photoplasma tube and the fan is not controlled, that is, S502 is executed.

[0125] If the odor concentration exceeds the threshold, it indicates an unpleasant odor inside the drum, potentially indicating the presence of bacteria, viruses, etc., requiring disinfection. In this case, both the photo-plasma tube and fan will operate at medium speed until the quick wash cycle ends, i.e., S503 is executed. The photo-plasma tube ionizes the air to generate a large amount of ionized matter. The fan quickly draws ambient air into the casing and rapidly delivers the gas containing more ionized matter into the drum, disinfecting the clothes and achieving a better sterilization effect.

[0126] Through the above control method, the operation of the photo-plasma tube and fan is not controlled when the odor concentration in the inner drum is low, and the photo-plasma tube and fan are operated throughout the entire quick wash mode when the odor concentration in the inner drum is high. This allows for better disinfection of the outer drum, inner drum, and clothes, resulting in better sterilization and reduced energy consumption.

[0127] In summary, in the preferred embodiment of the present invention, when the washing mode is quick wash mode, the operation of the photo-plasma tube and fan is controlled. Combining the operation of the photo-plasma tube and fan with the quick wash mode ensures that clothes are washed quickly to meet user needs while achieving a good sterilization effect. When the photo-plasma fresh air device is located below the outer drum, if the odor concentration is greater than a concentration threshold, it is determined whether the quick wash mode is in the spin-drying stage. If it is in the spin-drying stage, when the spin-drying duration exceeds a time threshold, the waterproof vent valve is opened, and the photo-plasma tube and fan are controlled to operate. After a preset time of operation, the photo-plasma tube and fan are stopped. When the spin-drying duration is less than or equal to the time threshold, the waterproof vent valve is not opened, and the photo-plasma tube and fan are not controlled to operate. If it is not in the spin-drying stage, the waterproof vent valve is not opened, and the photo-plasma tube and fan are not controlled to operate. Through this control method, a good sterilization effect can be achieved without damaging the photo-plasma fresh air device. When the photo-plasma fresh air device is installed above the outer cylinder, if the odor concentration is greater than the concentration threshold, the photo-plasma tube and fan will be controlled to run at medium speed until the quick wash mode ends. In this way, the photo-plasma tube and fan will run throughout the entire quick wash mode, thereby achieving a better sterilization effect.

[0128] Although the steps in the above embodiments are described in the above order, those skilled in the art will understand that in order to achieve the effect of this embodiment, different steps do not need to be executed in such order. They can be executed simultaneously (in parallel) or in reverse order. These simple changes are all within the protection scope of this application.

[0129] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles 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 such changes or substitutions will all fall within the scope of protection of the present invention.
