[0042] Please refer to Figures 1-3 The embodiment provides a clothes care method with hot air internal circulation, which is applied to a clothes care machine, and includes a machine body, an inner cylinder inside the machine body, and steps S11-S12, wherein:

[0043] S11, according to the instruction issued by the user, a corresponding working mode is selected, and the working mode at least includes a deep care mode and a scale removal mode.

[0044] In the embodiment, the deep care mode can directly remove the wrinkles of the clothes inside the inner drum and dry the clothes, and the scale removal mode can remove the scale generated by the deep care mode, and the working mode can be set by long pressing the power key for 2s.

[0045] S12, according to the working mode, executing the corresponding preset operation rule, the preset operation rule including preset deep care operation rule and preset scale removal operation rule.

[0046] In the embodiment, each corresponding working mode corresponds to an operation rule, and the operation rule can be set according to multiple parameter comparisons to achieve the best energy-saving effect.

[0047] As a preferred but not limited solution, step S12 further includes S121-S123, wherein:

[0048] S1211, according to the preset deep care operation rule, steam care is performed on the clothes in the inner drum.

[0049] In the embodiment, the water vapor is first attached to the clothes, and the hung clothes will naturally fall down due to gravity, thereby achieving the purpose of removing wrinkles. The care time is 15 minutes at the set temperature.

[0050] As a preferred but not limited solution, step S1211 further includes S12111-S12113, wherein:

[0051] S12111, water in the water tank is pumped to the evaporator by the water pump.

[0052] In the embodiment, the inner drum is arranged inside the machine body, and an operation space is arranged between the lower part of the inner drum and the machine body. The operation space is provided with a water tank and an evaporator, and a water pump is connected between the water tank and the evaporator, and

[0053] The evaporator is connected with the water pump to convert the liquid substance into gaseous substance. The water pump can help introduce the cooling medium or liquid into the evaporator, so as to ensure that the evaporator has enough cooling medium or liquid during operation to maintain the working efficiency of the evaporator.

[0054] S12112, when the evaporator temperature is lower than the preset temperature, stop adding water to the evaporator.

[0055] In this embodiment, when the evaporator is heated to the set temperature of 120°C, the water pump adds water to the evaporator from the clean water tank, and when the temperature of the evaporator is lower than the set temperature (95°C), the water pump stops adding water. A temperature controller is installed in the system, which monitors the temperature of the evaporator and compares it with the preset temperature. If the temperature of the evaporator is lower than the preset temperature, the controller may consider that the water is sufficient, so as to stop the water pump from adding water, so as to avoid excessive water addition and waste of resources.

[0056] S12113, according to the preset evaporator operation parameters, the water pumped in is evaporated and heated.

[0057] In this embodiment, the evaporator has a large power of 1350W, and steam is generated in the cavity after about 1 minute of care; the clothes are shaped, wrinkle-free and crease-free.

[0058] S1212, according to the preset operation rule, the clothes in the inner cylinder are deodorized, and the deodorization is performed by the plasma generator.

[0059] In this embodiment, the function of the plasma generator is sterilization, smoke elimination, dust removal and odor elimination. The care time can be 10 minutes at the set temperature, which is arranged on the upper side of the inner cylinder.

[0060] The drying care cycle includes the steps of: drawing hot air into the inner cylinder to absorb and discharge the water vapor generated by steam care; when the temperature rises to the preset temperature range, stopping the hot air from being drawn in, and running the inner circulating fan to make the hot air in the inner cylinder continuously circulate; and when the temperature in the inner cylinder is lower than the preset temperature range, continuously drawing in hot air to automatically discharge the air in the inner cylinder;

[0061] When the second drying care cycle is performed, the step of deodorizing the clothes in the inner cylinder according to the preset operation rule is performed simultaneously, and the deodorization is performed by the plasma generator.

[0062] In this embodiment, the first drying care cycle can have a care time of 30 minutes at the set temperature; in the first drying care cycle, the PTC heating body has a power of 800W and the perfusion fan works to generate hot air; the bottom air inlet door is opened, the high-speed fan generates strong convective hot air in the cavity, and the hot air is discharged from the top air outlet to accelerate the drying of the clothes; the second drying care cycle can have a care time of 20 minutes at the set temperature; in the second drying care cycle, the PTC heating body has a power of 800W and the perfusion fan works to generate hot air; the air inlet door is opened to generate strong convective hot air to accelerate the drying of the clothes; the bottom air inlet door is opened, the high-speed fan generates strong convective hot air in the cavity, and the hot air is discharged from the top air outlet to accelerate the drying of the clothes. The plasma generator and the UV lamp work together; the drying clothes are also sterilized and deodorized.

[0063] S1213, drawing in air outside the machine body by the perfusion fan.

[0064] In this embodiment, the perfusion fan is arranged in the operation space, the air inlet of the perfusion fan is communicated with the outside of the machine body, and the air outlet of the perfusion fan is connected with the inlet of the PCT heating body. The perfusion fan can be operated after receiving the start signal.

[0065] S1214, heating air outside the machine body by the PCT heating body to form the hot air.

[0066] In this embodiment, the outlet of the PTC heating body is communicated with the inner cylinder, and the outlet of the PTC heating body is separated from the air outlet of the cavity where the inner circulation fan is arranged. The PTC heating body has a power of 800 W, which can heat the air drawn into the machine body by the perfusion fan, generate hot air, and discharge the hot air into the inner cylinder.

[0067] S1215, drawing the hot air into the inner cylinder to absorb and discharge the water vapor generated in the steam care;

[0068] In this embodiment, after the steam care is completed, the surface of the clothes is wet, and the inner cylinder is filled with water vapor. After the hot air is drawn into the inner cylinder, the heat in the cylinder is accumulated and the temperature continues to rise.

[0069] S1216, when the temperature rises to the preset temperature range, stop drawing the hot air, and operate the inner circulation fan to continuously circulate the hot air in the inner cylinder;

[0070] In this embodiment, the hot air can absorb a certain amount of water vapor, because the higher the temperature, the greater the capacity of the air to contain water vapor. When the hot air contacts with the object or air containing water vapor, the water vapor in the object or air may be partially absorbed into the hot air, thereby reducing the content of water vapor in the environment. The clothes care machine includes a movable cover plate arranged between the inner cylinder and the machine body. The cover plate is hinged on one side of the inner cylinder. When the air pressure in the inner cylinder is greater than the air pressure outside the machine body, the cover plate is pushed out due to the pressure difference, and part of the air in the inner cylinder is discharged into the hot air that has absorbed the water vapor. This situation usually occurs when the drying care is started. The perfusion fan and the PTC heating body heat the air outside the machine body and introduce the air into the inner cylinder, or when the temperature in the inner cylinder is too low, the two are triggered to work to increase the air pressure inside the inner cylinder and discharge the relatively cold air inside the inner cylinder.

[0071] S1217, when the temperature in the inner cylinder is lower than the preset temperature range, continuously drawing the hot air to automatically discharge the air in the inner cylinder.

[0072] In this embodiment, when the temperature inside the inner cylinder is too low, the perfusion fan and the heating body PCT will heat the air outside the machine body and introduce it into the inner cylinder to increase the air pressure inside the inner cylinder and expel the relatively cold air inside the inner cylinder.

[0073] When the temperature inside the inner cylinder is lower than the preset temperature range, the hot air is continuously pumped in. When the air pressure inside the inner cylinder is greater than the air pressure outside the machine body, the hot air inside the inner cylinder can be expelled to the outside of the machine body by using the pressure difference. As a preferred but not limited solution, the relative position of the perfusion fan and the cover plate in the machine body is set to further improve the exhaust efficiency of the wet and cold air. This is achieved by the cover plate, which is hinged at one end to the top of the inner cylinder on one side of the exhaust hole. When the air pressure inside the inner cylinder is high, the cover plate body can be lifted to expel the air inside the inner cylinder.

[0074] S122, according to the preset scale removal operation rule, the clothes in the inner cylinder are treated for scale removal.

[0075] In this embodiment, scale removal is also for energy saving. Scale can form a barrier layer on the surface of heat exchangers, pipes and other equipment, hindering heat transfer and fluid flow, resulting in increased energy loss and reduced equipment efficiency. By removing scale, the heat transfer and fluid flow capacity of the equipment can be improved, reducing energy loss and achieving energy saving.

[0076] As a preferred but not limited solution, step S122 further includes S1221-S1224.

[0077] S1221, add scale dissolving agent to the water tank.

[0078] In this embodiment, the scale dissolving agent can be citric acid. The specific steps are to automatically inject 50g of citric acid into the water tank, and the water level in the water tank reaches the top of the water level gauge.

[0079] S1222, receive the user's scale removal start instruction, and pump the water in the water tank to the evaporator by the water pump.

[0080] In this embodiment, the user confirms to perform scale removal by pressing the start button, which can start the water pump to pump water to the evaporator for about 50 seconds, i.e. 200-300ml of water is injected.

[0081] S1223, after a preset time, pump the water in the evaporator to the scale tank by the water pump.

[0082] In this embodiment, the evaporator works at a temperature of 85℃, and after 38 minutes, the water in the evaporator is pumped into the scale tank for about 1 minute, i.e. the water volume is 260-360ml / min.

[0083] S1224, when detecting that the scale water tank is full, the water pump is used to discharge the water in the scale water tank to the outside of the machine body.

[0084] In this embodiment, when the water level detection device detects that the scale water tank is full, the water pump is started to discharge the water in the scale water tank.

[0085] S123, according to the open-door power-off operation rule, the open-door power-off mode is executed.

[0086] When it is detected that the clothes care machine door is open, the open-door power-off mode is automatically entered, which is used at least to pause the current work.

[0087] The prototype test data of this embodiment is as follows:
