[0003] For example, existing garment care machines have multiple functions such as sterilization, disinfection, wrinkle removal, deodorization, drying, and shaping, which greatly reduces the workload of users in the garment care process, improves care efficiency, and makes clothes cleaner and more hygienic.

[0004] However, existing garment care machines are prone to causing clothes to become damp and develop a musty smell after the garments have been cared for, which greatly affects the care effect and the user experience.

[0005] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0006] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem that existing garment care machines are prone to dampness and musty smell after garment care, which greatly affects the garment care effect and user experience.

[0007] In a first aspect, the present invention provides a control method for a garment care machine, the garment care machine comprising: a housing having a care chamber and a circulating air duct, the care chamber being capable of accommodating garments to be cared for, and the air outlet and return air outlet of the circulating air duct being connected to the care chamber; a fan installed in the circulating air duct and capable of generating circulating airflow; a heat pump module having a condenser and an evaporator installed in the circulating air duct, the condenser being capable of heating the circulating airflow, and the evaporator being capable of dehumidifying the circulating airflow; an exhaust channel having one end connected to the housing and the other end connected to the outside of the housing; a vent valve installed in the exhaust channel and capable of controlling the opening and closing of the exhaust channel; and an exhaust fan installed in the exhaust channel and capable of drawing air from the housing to the outside of the housing. The control method of the present invention comprises: after the drying mode ends, acquiring the air humidity in the care chamber or the circulating air duct; and selectively controlling the vent valve and the exhaust fan to open based on the air humidity.

[0008] In the preferred embodiment of the above control method, the step of "selectively controlling the ventilation valve and the exhaust fan to open according to the air humidity" specifically includes: comparing the air humidity with a preset humidity; and selectively controlling the ventilation valve and the exhaust fan to open according to the comparison result.

[0009] In the preferred embodiment of the above control method, the step of "selectively controlling the ventilation valve and the exhaust fan to open according to the comparison result" specifically includes: if the air humidity is greater than the preset humidity, then controlling the ventilation valve and the exhaust fan to open; and / or if the air humidity is not greater than the preset humidity, then not controlling the ventilation valve and the exhaust fan to open.

[0010] In the preferred embodiment of the above control method, the step of "controlling the ventilation valve and the exhaust fan to open" specifically includes: controlling the ventilation valve and the exhaust fan to open intermittently.

[0011] In a preferred embodiment of the above control method, the garment care machine further includes an auxiliary heating device installed in the circulating air duct. When the ventilation valve and the exhaust fan are not turned on, the control method of the present invention further includes controlling the operation of the auxiliary heating device.

[0012] In the preferred embodiment of the above control method, before "controlling the operation of the auxiliary heating device", the control method of the present invention further includes: acquiring the temperature in the nursing chamber or the circulating air duct; and selectively controlling the operation of the auxiliary heating device according to the temperature.

[0013] In the preferred embodiment of the above control method, the step of "selectively controlling the operation of the auxiliary heating device according to the temperature" specifically includes: comparing the temperature with a preset temperature; and selectively controlling the operation of the auxiliary heating device according to the comparison result.

[0014] In the preferred embodiment of the above control method, the step of "selectively controlling the operation of the auxiliary heating device according to the comparison result" specifically includes: if the temperature is less than the preset temperature, then controlling the operation of the auxiliary heating device; and / or if the temperature is not less than the preset temperature, then not controlling the operation of the auxiliary heating device.

[0015] In the preferred embodiment of the above control method, while "controlling the ventilation valve and the exhaust fan to turn on", the control method of the present invention further includes: controlling the fan to turn on.

[0016] In a second aspect, the present invention provides a garment care machine, the garment care machine including a controller configured to perform the control method described above.

[0017] With the above technical solution adopted, the garment care machine of the present invention includes: a housing, the housing having a care chamber and a circulating air duct, the care chamber being able to accommodate garments to be cared for, and the air outlet and air return outlet of the circulating air duct being connected to the care chamber; a fan, the fan being installed in the circulating air duct and capable of generating circulating airflow; a heat pump module, the condenser and evaporator of the heat pump module being installed in the circulating air duct, the condenser being capable of heating the circulating airflow, and the evaporator being capable of dehumidifying the circulating airflow; an exhaust channel, one end of the exhaust channel being connected to the housing, and the other end of the exhaust channel being connected to the outside of the housing; a vent valve, the vent valve being installed in the exhaust channel and capable of controlling the opening and closing of the exhaust channel; and an exhaust fan, the exhaust fan being installed in the exhaust channel and capable of drawing air from the housing to the outside of the housing; the control method of the present invention includes: after the drying mode ends, obtaining the air humidity in the care chamber or the circulating air duct; and selectively controlling the vent valve and the exhaust fan to open according to the air humidity. This design allows for selective dehumidification of the care chamber and circulating air duct within the machine based on the humidity level inside. This prevents moisture from being trapped in the care chamber and circulating air duct, which could cause clothes to become damp or even moldy, thus improving the care effect and user experience. At the same time, it prevents electrical and mechanical components inside the machine from being damaged by moisture, reducing the failure rate, improving the operational stability of the garment care machine, and extending its service life.

[0018] Furthermore, the control method of the present invention also includes: comparing the air humidity with a preset humidity; and selectively controlling the opening of the ventilation valve and the exhaust fan based on the comparison result. With this setting, the critical humidity for clothes to become damp can be determined using the preset humidity, and by setting the preset humidity as the opening condition for the ventilation valve and the exhaust fan, the air humidity inside the drying chamber can be controlled within a reasonable range after the drying mode ends.

[0019] Furthermore, the control method of the present invention also includes: if the air humidity is greater than a preset humidity, controlling the ventilation valve and exhaust fan to open; and / or if the air humidity is not greater than the preset humidity, not controlling the ventilation valve and exhaust fan to open. With this setting, the ventilation valve and exhaust fan can be opened when the air humidity exceeds a critical humidity level to promptly remove residual moisture from the care chamber and circulating air duct, preventing clothing from becoming damp and moldy in a humid environment; when the air humidity is not greater than the critical humidity level, the residual moisture is evaporated by the residual heat in the circulating air duct, eliminating the need to open the ventilation valve and exhaust fan to save energy, effectively balancing the needs of dehumidification and energy saving.

[0020] Furthermore, the control method of the present invention also includes: controlling the vent valve and exhaust fan to open intermittently. With this setting, when the vent valve and exhaust fan are closed, the residual heat inside the chamber can be used to accelerate the evaporation of moisture and prevent moisture accumulation; when the vent valve and exhaust fan are open, water vapor can be concentratedly discharged, which helps to improve the dehumidification efficiency.

[0021] Furthermore, the garment care machine of the present invention also includes an auxiliary heating device installed in the circulating air duct. When the vent valve and exhaust fan are not turned on, the control method of the present invention further includes controlling the operation of the auxiliary heating device. With this configuration, the operation of the auxiliary heating device can maintain a higher temperature in the circulating air duct and the care chamber, which helps to improve the evaporation efficiency of moisture and accelerate the removal of moisture.

[0022] Furthermore, prior to "controlling the operation of the auxiliary heating device", the control method of the present invention further includes: acquiring the temperature in the nursing chamber or circulating air duct; and selectively controlling the operation of the auxiliary heating device based on the temperature.

[0023] Furthermore, the control method of the present invention also includes: comparing the temperature with a preset temperature; and selectively controlling the operation of the auxiliary heating device based on the comparison result. Through this setting, the suitable temperature range for moisture evaporation can be determined using the preset temperature. By setting the preset temperature as the activation condition for the auxiliary heating device, the circulating air duct and the nursing chamber can always be maintained within the suitable evaporation temperature range, thereby ensuring the evaporation efficiency and amount of moisture.

[0024] Furthermore, the control method of the present invention further includes: controlling the auxiliary heating device to operate if the temperature is lower than a preset temperature; and / or not controlling the auxiliary heating device to operate if the temperature is not lower than the preset temperature. With this configuration, while ensuring the evaporation efficiency and amount of water, energy consumption can be effectively saved and operating costs reduced.

[0025] Furthermore, in addition to controlling the opening of the vent valve and exhaust fan, the control method of this invention also includes controlling the opening of the fan. This arrangement accelerates the removal of moisture from the chamber, especially near the evaporator, thereby improving the evaporation efficiency of the moisture.

[0026] Furthermore, the garment care machine provided by this invention, based on the aforementioned control method, possesses the technical effects of the aforementioned control method. Compared to the garment care machine before the improvement, the garment care machine of this invention can promptly expel residual moisture in the care chamber and circulating air duct after garment care, ensuring the cleanliness and dryness of the machine's interior, preventing garments from becoming damp and moldy in a humid environment, improving the garment care effect and user experience, while also protecting the machine and extending its service life.

[0035] 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 present invention and are not intended to limit the scope of protection of the present invention.

[0036] It should be noted that in the description of this invention, terms such as "inner," "outer," etc., indicating direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0038] As noted in the background section, existing garment care machines are prone to causing clothes to become damp and develop a musty smell after care, significantly impacting the garment care effect and user experience. This invention provides a control method and a garment care machine. By incorporating an exhaust channel, a vent valve, and an exhaust fan into the machine, and controlling the activation and deactivation of the vent valve and exhaust fan based on the humidity inside the machine, the machine can effectively expel humid air from the machine when humidity is high, preventing clothes from becoming damp or even moldy. Conversely, when humidity is low, the vent valve and exhaust fan are shut off, allowing moisture to evaporate naturally, thus saving energy.

[0039] Specifically, such as Figure 1 and Figure 2 As shown, the garment care machine of the present invention is configured with a housing 1 structure, and the internal space of the housing 1 is divided into a care chamber 11 and a circulating air duct 12. The care chamber 11 is used to accommodate the garments to be cared for, and the two ends of the circulating air duct 12 are respectively provided with an air outlet 13 and an air return outlet 14, and the circulating air duct 12 and the care chamber 11 are connected through the air outlet 13 and the air return outlet 14.

[0040] Inside the circulating air duct 12, a fan 2 and a heat pump module are installed. When the fan 2 is running, it blows air from the circulating air duct 12 into the nursing chamber 11 through the air outlet 13, and simultaneously draws air from the nursing chamber 11 into the circulating air duct 12 through the air return outlet 14, thus forming a circulating airflow. The heat pump module includes a condenser 31 and an evaporator 32. Through the heat exchange circulation of the refrigerant, one of the condenser 31 and the evaporator 32 can heat while the other cools, so as to heat and dehumidify the low-temperature, high-humidity airflow entering the circulating air duct 12 respectively.

[0041] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, an auxiliary heating device 5 is also installed in the circulating air duct 12. The auxiliary heating device 5 is usually set as an electric heating module such as PTC, which has the advantages of fast heating and high control accuracy. It can supplement the heat loss in the air duct and improve thermal efficiency.

[0042] For example, in this application, by controlling the flow direction of the refrigerant, the condenser 31 is heated to heat the circulating airflow entering the circulating air duct 12; at the same time, the evaporator 32 is cooled to reach the dew point temperature of water vapor, so that the water vapor in the circulating airflow is pre-condensed into water droplets, and the circulating airflow is dehumidified by the centralized treatment of the water droplets.

[0043] However, after the drying mode ends, some condensate will still accumulate on the inner walls of the care chamber 11 and the circulating air duct 12 (especially inside the circulating air duct 12), resulting in high humidity in the care chamber 11 and the circulating air duct 12. Since the clothes will be stored in the care chamber 11, they will become damp or even moldy after a period of time, and produce a musty smell, which seriously affects the care effect of the clothes and the user experience.

[0044] Based on the above issues, such as Figure 1 and Figure 2 As shown, the garment care machine of the present invention is provided with an exhaust channel, an air vent valve 41, and an exhaust fan 42. The exhaust channel is provided on the housing 1. Preferably, the exhaust channel connects the care chamber 11 to the outside of the housing 1 so as to realize air circulation inside and outside the care chamber 11, which helps to ventilate the garment. The air vent valve 41 is installed in the exhaust channel and can control the opening and closing of the exhaust channel. The exhaust fan 42 is also installed in the exhaust channel and can draw the air inside the care chamber 11 to the outside of the housing 1, and can also draw the outside air into the care chamber 11.

[0045] It should be noted that, in practical applications, those skilled in the art can flexibly set the structure of the exhaust channel, such as ventilation ducts or vents, as long as it can achieve air circulation inside and outside the nursing chamber 11. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be limited to the protection scope of the present invention.

[0046] Therefore, the control method of the present invention can control the ventilation valve 41 and the exhaust fan 42 to open after the drying mode ends, so as to discharge the moisture in the nursing chamber 11 and the circulating air duct 12 and keep the inside of the box 1 dry.

[0047] Preferably, such as Figure 3 As shown, the control method of the present invention specifically includes:

[0048] S100: After the drying mode ends, obtain the air humidity in the care chamber or circulating air duct;

[0049] S200: Selectively controls the opening of the ventilation valve and exhaust fan based on air humidity.

[0050] Specifically, after the drying mode ends, the heating device and fan 2 stop operating. At this time, the humidity inside the chamber 1 is detected by the humidity sensor installed inside the chamber 1. In practical applications, the humidity sensor can be flexibly installed anywhere inside the nursing chamber 11 or the circulating air duct 12. Since the dehumidification process of the evaporator 32 is carried out in the circulating air duct 12, a lot of condensate accumulates in the circulating air duct 12, making the air humidity in the circulating air duct 12 the highest. Therefore, the present invention preferably installs the humidity sensor in the circulating air duct 12 to accurately obtain the humidity inside the chamber 1.

[0051] After accurately obtaining the air humidity inside the enclosure 1, the controller will control the ventilation valve 41 and the exhaust fan 42 according to the preset control program.

[0052] Preferably, such as Figure 4 As shown, the steps of "selectively controlling the ventilation valve and exhaust fan to operate based on air humidity" specifically include:

[0053] S210: Compare the air humidity with the preset humidity;

[0054] S220: Based on the comparison results, selectively control the opening of the vent valve and exhaust fan.

[0055] The preset humidity can be used to determine the critical humidity for clothes to become damp. That is, when the drying mode ends and the air humidity in the circulating air duct 12 reaches the preset humidity, it means that there is a lot of moisture accumulated in the cabinet 1, which is difficult to evaporate naturally, and will eventually lead to clothes becoming damp and moldy.

[0056] Therefore, the preset humidity is set as the opening condition for the ventilation valve 41 and the exhaust fan 42. When the air humidity reaches the preset humidity, the ventilation valve 41 and the exhaust fan 42 will be opened to expel the moisture in the box 1, thereby controlling the air humidity in the box 1 within a reasonable range and preventing clothes from becoming damp and moldy.

[0057] It should be noted that the preset humidity can be flexibly set according to the indoor or outdoor air humidity where the garment care machine is located, or it can be set to a fixed value. In this invention, it is preferred to set the preset humidity to be slightly higher than the indoor air humidity, such as 40% to 60%.

[0058] With this setup, the air circulation duct 12 and the care chamber 11 can be selectively dehumidified according to the air humidity inside the air circulation duct 12, preventing moisture from being sealed inside the box 1 and causing clothes to become damp or even moldy, thus improving the care effect of clothes and the user experience; at the same time, it avoids damage to the electrical and mechanical components inside the machine due to moisture, reduces the failure rate, improves the operational stability of the garment care machine, and extends its service life.

[0059] Preferably, such as Figure 4 As shown, the steps of "selectively controlling the ventilation valve and exhaust fan to open based on the comparison results" specifically include:

[0060] S221: If the air humidity is greater than the preset humidity, control the ventilation valve and exhaust fan to turn on;

[0061] S222: If the air humidity is not greater than the preset humidity, the ventilation valve and exhaust fan will not be turned on.

[0062] Specifically, when the air humidity is greater than the preset humidity, it means that the air humidity in the circulating air duct 12 is much greater than the indoor air humidity, and there is a lot of water inside, which cannot be dried naturally. It is necessary to open the ventilation valve 41 and the exhaust fan 42 to discharge the moisture in the box 1 in order to reduce the air humidity in the box 1.

[0063] When the air humidity is not greater than the preset humidity, it means that the air humidity in the circulating air duct 12 is close to or slightly greater than the indoor air humidity. There is little water inside, which can evaporate naturally in a short time, thereby reducing the air humidity in the box 1 to the indoor air humidity. At this time, there is no need to open the ventilation valve 41 and exhaust fan 42 to save energy and effectively meet the needs of dehumidification and energy saving.

[0064] Furthermore, when the air humidity is high and the ventilation valve and exhaust fan 42 are turned on, the control method of the present invention adopts a method of controlling the ventilation valve and exhaust fan 42 to turn on intermittently.

[0065] Preferably, such as Figure 5 As shown, the specific steps for "controlling the ventilation valve and exhaust fan to turn on" include:

[0066] Control the ventilation valve and exhaust fan to turn on intermittently.

[0067] That is, after the drying mode ends, the ventilation valve 41 and the exhaust fan 42 are first controlled to open for a first preset time, and then the ventilation valve 41 and the exhaust fan 42 are controlled to close for a second preset time, and this process is repeated multiple times.

[0068] Thus, water vapor can be concentrated and discharged within the first preset time of opening the ventilation valve and exhaust fan 42, which helps to improve the dehumidification efficiency; within the second preset time of closing the ventilation valve 41 and exhaust fan 42, the residual heat inside the box 1 can be used to accelerate the evaporation of moisture and prevent the accumulation of moisture.

[0069] In practical applications, both the first preset time and the second preset time can be flexibly set according to the actual situation. In this invention, it is preferred to set the first preset time to 3 to 5 minutes and the second preset time to 30 to 35 minutes to achieve the best dehumidification effect.

[0070] It should also be noted that the vent valve 41 and the exhaust fan 42 can be opened simultaneously, or the vent valve 41 can be opened first and then the exhaust fan 42 can be opened.

[0071] In addition, the evaporation efficiency of water during the dehumidification process is also affected by temperature. If the temperature is too low, it will not be conducive to the evaporation of water. Therefore, in a preferred embodiment of the control method of the present invention, the temperature inside the box 1 is also controlled to improve the evaporation efficiency of water.

[0072] Preferably, during the period when the vent valve 41 and the exhaust fan are not turned on, the control method of the present invention further includes:

[0073] Control the operation of the auxiliary heating device.

[0074] Especially when the ambient temperature is low, the temperature inside the chamber 1 drops rapidly, which reduces the evaporation efficiency of moisture. At this time, the auxiliary heating device 5 is used to heat the air in the circulating air duct 12, so that the circulating air duct 12 and the nursing chamber 11 can maintain a high temperature, which helps to improve the evaporation efficiency of moisture and accelerate the discharge of moisture.

[0075] At the same time, while considering the evaporation temperature, the energy consumption of the garment care machine should also be controlled. For example, when the ambient temperature is high, there is no need to run the auxiliary heating device.

[0076] Therefore, preferably, such as Figure 5 As shown, before "controlling the operation of the auxiliary heating device", the control method of the present invention further includes:

[0077] S300: Obtains the temperature within the nursing chamber or circulating air duct;

[0078] S400: Selectively controls the operation of the auxiliary heating device based on temperature.

[0079] Preferably, such as Figure 5 As shown, the steps of "selectively controlling the operation of the auxiliary heating device according to temperature" specifically include:

[0080] S410: Compare the temperature with the preset temperature;

[0081] S420: Based on the comparison results, selectively control the operation of the auxiliary heating device.

[0082] Preferably, such as Figure 5 As shown, the steps of "selectively controlling the operation of the auxiliary heating device based on the comparison results" specifically include:

[0083] S421: If the temperature is lower than the preset temperature, control the auxiliary heating device to operate;

[0084] S422: If the temperature is not lower than the preset temperature, the auxiliary heating device will not be controlled to operate.

[0085] Preferably, the preset temperature in this invention is set to 50°C. By setting the preset temperature, the suitable temperature range for water evaporation can be determined. Setting the preset temperature as the activation condition of the auxiliary heating device 5 ensures that the circulating air duct 12 and the nursing chamber 11 are always kept in the suitable evaporation temperature range, so as to ensure the evaporation efficiency and evaporation amount of water. At the same time, while ensuring the evaporation efficiency and evaporation amount of water, it can also effectively save energy consumption and reduce the operating cost.

[0086] Furthermore, in a preferred embodiment, while controlling the ventilation valve and exhaust fan to turn on, the control method of the present invention further includes:

[0087] Control the fan to start.

[0088] When the fan 2 is turned on, it can accelerate the flow of moisture in the circulating air duct 12 to the outside of the nursing chamber 11 and the box 1, which helps to remove moisture, especially the moisture near the evaporator 32, and improves the evaporation efficiency of water.

[0089] Furthermore, the garment care machine provided by this invention, based on the aforementioned control method, possesses the technical effects of the aforementioned control method. Compared to the garment care machine before the improvement, the garment care machine of this invention can promptly expel residual moisture in the care chamber 11 and the circulating air duct 12 after garment care, ensuring the cleanliness and dryness of the machine's interior, preventing garments from becoming damp and moldy in a humid environment, improving the garment care effect and user experience, while also protecting the machine and extending its service life.

[0090] In a preferred embodiment of the garment care machine of the present invention, an ozone generator is also installed in the circulating air duct 12 or the care chamber 11 of the garment care machine to generate ozone ions and eliminate odors in the housing 1.

[0091] 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.
