[0048] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0049] Current clothing processing equipment uses temperature sensors to detect changes in the dehumidification rate of the air after condensation during the drying process, thus adjusting the equipment's operation accordingly. However, this method is slow to detect problems and cannot adjust the equipment's operation in a timely manner. This invention provides a washing machine that can detect the inlet temperature of the condensate water to determine whether the dehumidification rate matches the moisture retention rate, thereby regulating the clothing processing equipment's operation in real time and ensuring a balanced drying heat cycle.

[0050] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 The technical solution of this embodiment is described in detail. Unless otherwise specified, the following implementation methods and embodiments can be combined with each other.

[0051] Example 1

[0052] like Figures 1-2 As shown, this embodiment proposes a drying control method for a garment processing device. The garment processing device is equipped with a drying air path, which includes a condensation section, a heating section, and a drying fan that provides airflow power to the drying air path. The condensation section is equipped with a condensate cooling structure to cool and dehumidify the drying airflow in the drying air path. The heating section is equipped with heating elements to heat the cooled and dehumidified drying airflow. The drying control method includes:

[0053] In drying mode, the temperature value of the cooling water is obtained, the dehumidification capacity of the clothing processing equipment is determined based on the temperature value of the cooling water, and the moisture carrying capacity of the clothing processing equipment is adjusted based on the dehumidification capacity of the clothing processing equipment.

[0054] Adjusting the moisture carrying capacity of the clothing processing equipment according to its dehumidification capacity includes: adjusting the operating parameters of the clothing processing equipment according to its dehumidification capacity.

[0055] The operating parameters of the garment processing equipment shall include at least the output power of the heating element and / or the output power of the fan and / or the load of the garment processing equipment.

[0056] In the drying mode of the clothing processing device in this embodiment of the invention, by acquiring the temperature value of the cooling water, the main control program of the clothing processing device can calculate the maximum dehumidification capacity that the clothing processing device can achieve at the cooling water temperature. Then, by acquiring the current output power of the heating element, the output power of the fan, and the load, the main control program calculates the current moisture content of the clothing processing device, and adjusts the moisture content based on the dehumidification value, thereby adjusting the clothing processing device to an optimal moisture content and dehumidification capacity, so that the drying effect of the clothing processing device reaches the optimal level.

[0057] It should be noted that the cooling water in the embodiments of the present invention refers to the water in the tap water pipe. Therefore, the temperature of the cooling water will change in different seasons and at different times, which will lead to changes in the dehumidification capacity of the clothing treatment equipment.

[0058] It should also be noted that the obtained condensate temperature value can be either the temperature of the condensate in the inlet pipe or the temperature of the condensate in the drying fan. However, it is preferable to obtain the temperature value of the condensate in the inlet pipe of the garment processing equipment.

[0059] Specific;

[0060] During the drying process, the rate at which the hot and humid air blown out by the fan is condensed fluctuates as the temperature of the cooling water rises or falls.

[0061] Specifically, when the cooling water temperature increases, the condensation rate decreases, and the humid air is heated and blown back into the garment processing drum before it can be condensed. Although the moisture-carrying capacity remains unchanged, the overall moisture-carrying effect of the garment processing equipment decreases because some humid air returns to the garment processing drum each time. This prolongs the entire drying time and may even cause the entire drying process to fail, requiring additional drying time. This will greatly increase the energy consumption of the drying process, and the excessively long drying time will also damage some types of clothing.

[0062] Specifically, when the cooling water temperature drops, the condensation rate will be too fast. However, after the water vapor in the humid air is condensed, the cooling water continues to exchange heat with the air, which will lower the temperature of the condensed air. When the low-temperature air circulates to the heating tube, it needs to be heated to its previous temperature to maintain its original moisture-carrying capacity. However, the air temperature is lower than before, so more heat is needed to heat the air back to its original intake temperature. Since the energy provided by electric heating is fixed, this also prolongs the drying time or causes the drying process to fail.

[0063] Therefore, in order to ensure that the amount of moisture carried and the amount of dehumidification in the drying heat cycle are matched, and in view of the possible changes in the cooling water temperature, this embodiment of the invention utilizes the relationship between the dehumidification capacity brought by different cooling water temperatures and the moisture carrying capacity brought by different air volumes and / or different heat volumes. A temperature sensor is used to detect the temperature of the condensate in real time, so as to adjust the output energy of the electric heating element and / or the output air volume of the fan.

[0064] It should be noted that the dehumidification capacity and moisture carrying capacity mentioned above in the embodiments of the present invention can be understood as dehumidification capacity and moisture carrying capacity.

[0065] Specifically, the ability of cooling water to remove moisture from humid air after heat exchange can be understood as dehumidification capacity. Moisture-retaining capacity can be understood as follows: moisture in clothing is heated and evaporated, but accumulates in the garment processing drum, awaiting condensation by the fan. This process is called moisture retention, and the amount of moisture removed is the moisture-retaining capacity. Moisture-retaining capacity is determined by factors such as fan power, electric heating power, and the amount of clothing.

[0066] Furthermore, to optimize the drying effect of the garment processing equipment, methods for adjusting the moisture carrying capacity of the garment processing equipment based on its dehumidification capacity include:

[0067] Determine whether the dehumidification capacity of the garment processing equipment is the same as the moisture retention capacity of the garment processing equipment;

[0068] If they are different, adjust the moisture carrying capacity of the garment processing equipment to be the same as the dehumidification capacity of the garment processing equipment.

[0069] In other words, by adjusting the moisture content of the clothing processing equipment to be equal to the dehumidification content, the dryer can ensure a balanced drying heat cycle, thereby achieving the best drying effect.

[0070] Furthermore, methods for adjusting the moisture carrying capacity of the garment processing equipment to be the same as the dehumidification capacity of the garment processing equipment include:

[0071] The amount of moisture carried by the garment processing equipment is adjusted by regulating the output power of the heating element and / or the output power of the fan.

[0072] In this embodiment of the invention, when adjusting the moisture carrying capacity of the clothing processing equipment, the moisture carrying capacity can be changed by altering the output power of the heating element and / or the output power of the fan, so that the moisture carrying capacity and the dehumidification capacity remain the same.

[0073] Furthermore, methods for adjusting the moisture content of clothing handling equipment by adjusting the output power of the heating element and / or the output power of the fan include:

[0074] The output power of the heating element and / or the output power of the fan can be changed by altering the input voltage of the heating element and / or the input voltage of the fan.

[0075] Of course, in some alternative implementations, the output power of the heating element and / or the output power of the fan can also be changed by altering the input current of the heating element and / or the input current of the fan.

[0076] It is worth noting that the dehumidification capacity of the garment processing equipment is directly proportional to the temperature of the cooling water;

[0077] The amount of moisture carried by the clothing processing equipment is directly proportional to the output power of the heating element and the output power of the fan.

[0078] That is, when the amount of moisture carried is less than the amount of dehumidification, the amount of moisture carried can be increased by increasing the output power of the heating element and the output power of the fan. When the amount of moisture carried is greater than the amount of dehumidification, the amount of moisture carried can be reduced by decreasing the output power of the heating element and the output power of the fan.

[0079] In any of the above embodiments, the clothing processing equipment is pre-set with a {dehumidification capacity - heating element output power value} lookup table;

[0080] Methods for adjusting the moisture carrying capacity of the garment processing equipment to be the same as the dehumidification capacity of the garment processing equipment include:

[0081] Based on the determined dehumidification amount, retrieve the corresponding heating element output power value from the preset {dehumidification amount - heating element output power value} lookup table, and adjust the moisture carrying capacity of the clothing processing equipment according to the retrieved heating element output power value so that the moisture carrying capacity of the clothing processing equipment is the same as the dehumidification amount.

[0082] Taking adjusting the output power of the heating element as an example, when it is necessary to adjust the moisture carrying capacity to be the same as the dehumidification capacity, the output power value of the heating element corresponding to the dehumidification capacity can be retrieved from the {Dehumidification Capacity - Heating Element Output Power Value} lookup table according to the dehumidification capacity calculated by the main control program. The input voltage value required at that output power is calculated based on the retrieved output power value of the heating element. By changing the input voltage of the heating element, the output power value of the heating element is changed, thereby changing the moisture carrying capacity of the clothing processing equipment {as mentioned above, the change of the output power of the heating element can change the size of the moisture carrying capacity}, so that the moisture carrying capacity and the dehumidification capacity of the clothing processing equipment are the same.

[0083] Specifically, the temperature difference of cooling water may range from 5℃ to 35℃ in different seasons {this temperature difference refers to the temperature difference of cooling water under normal operating conditions}. The condensate temperature under normal operating conditions is set at 25℃. Taking 5℃ as a stage, for every 5℃ increase or decrease in temperature, the corresponding electric heating output power increases or decreases by 5W. There will always be a corresponding relationship, so that the temperature change of condensate water and the amount of moisture carried and dehumidified by the electric heating output power are kept in balance, thereby ensuring the drying efficiency of the clothing processing equipment.

[0084] Of course, the correspondence between temperature and electric heating does not necessarily have to be 5 degrees and 5W. In actual products, the electric heating specifications can be different for different models, so that each model of garment processing equipment has its own suitable correspondence.

[0085] For example, when the cooling water temperature is 15℃, the water temperature sensor detects and returns the condensate temperature. The main control program then determines the maximum dehumidification capacity that the garment processing equipment can achieve at the current water temperature. Based on this, it calculates the power output of the electric heater to meet the dehumidification capacity at this time, ensuring that the dehumidification capacity is equal to the moisture retention capacity, thus guaranteeing the balance of the drying heat cycle.

[0086] In summary, by directly detecting the cooling water temperature and adjusting the output power of the electric heater based on the relationship between the cooling water temperature and the condensation efficiency, the heat output is precisely controlled, and the moisture-carrying capacity of the clothing processing equipment is adjusted. This ensures that the clothing processing equipment can maintain a balance in the drying heat cycle and guarantee drying efficiency even when facing water temperature changes caused by seasonal and weather changes.

[0087] Of course, in some alternative implementations, when adjusting the moisture content of the garment processing equipment, the moisture content can be adjusted by adjusting the output power of the heating element or by adjusting the output power of the fan, depending on the situation.

[0088] Specifically, the clothing processing equipment has a pre-set table for the following parameters: {Dehumidification capacity - Heating element output power value - Fan output power value}.

[0089] Methods for adjusting the moisture carrying capacity of the garment processing equipment to be the same as the dehumidification capacity of the garment processing equipment include:

[0090] Based on the determined dehumidification capacity, retrieve the corresponding heating element output power value or fan output power value from the preset {dehumidification capacity - heating element output power value - fan output power value} lookup table. Adjust the moisture carrying capacity of the clothing processing equipment according to the retrieved heating element output power value or fan output power value so that the moisture carrying capacity of the clothing processing equipment is the same as the dehumidification capacity.

[0091] Furthermore, the method for retrieving the corresponding output power value of the heating element or the output power value of the fan from a preset lookup table of {dehumidification capacity - heating element output power value - fan output power value} includes:

[0092] Obtain the moisture content of the clothing processing equipment in the current state, compare the moisture content and dehumidification of the clothing processing equipment in the current state, and based on the comparison result of moisture content and dehumidification, retrieve the corresponding output power value of the heating element or the output power value of the fan from the {dehumidification amount - heating element output power value - fan output power value} lookup table.

[0093] Specifically, methods for retrieving the corresponding heating element output power value or fan output power value from the {Dehumidification Capacity - Heating Element Output Power Value - Fan Output Power Value} lookup table based on the comparison results of moisture carrying capacity and dehumidification capacity include:

[0094] If the amount of moisture carried is less than the amount of dehumidification, then retrieve the corresponding fan output power value from the {Dehumidification amount - Heating element output power value - Fan output power value} lookup table, and adjust the amount of moisture carried by the clothing processing equipment according to the retrieved fan output power value so that the amount of moisture carried by the clothing processing equipment is the same as the amount of dehumidification.

[0095] If the moisture carrying capacity is greater than the dehumidification capacity, then retrieve the corresponding heating element output power value from the {Dehumidification capacity - Heating element output power value - Fan output power value} lookup table, and adjust the moisture carrying capacity of the clothing processing equipment according to the retrieved heating element output power value so that the moisture carrying capacity of the clothing processing equipment is the same as the dehumidification capacity.

[0096] In this embodiment, different adjustment schemes can be selected according to the magnitude of the moisture carrying capacity and the dehumidification capacity. That is, when the moisture carrying capacity is less than the dehumidification capacity, the moisture carrying capacity is increased by increasing the output power of the fan, and when the moisture carrying capacity is greater than the dehumidification capacity, the moisture carrying capacity is reduced by reducing the electric heating power.

[0097] The reason why the moisture content of the clothing processing equipment is changed according to the above control logic in this embodiment is mainly because: when the electric heating output power is too high, the temperature inside the clothing processing drum is too high, which will damage the clothes. Therefore, when it is necessary to increase the moisture content of the clothing processing equipment, instead of increasing the electric heating output power, the air volume is increased to avoid the drying temperature being too high and damaging the clothes.

[0100] Monitor the condensate water temperature during the drying process;

However, it is preferable to obtain the temperature value of the condensate in the inlet pipe of the garment processing equipment.
