Description

[Technical Field]

[0001] (Related Applications) This application claims priority to Chinese Patent Applications Nos. 202211060628.1 and 202211057592.1, filed on August 31, 2022, the entire contents of which are incorporated herein by reference.

[0002] (Technical field) The present application relates to the field of household appliances, and in particular to clothing treatment devices. [Background technology]

[0003] As people's living standards improve, more and more consumers are demanding more efficient and convenient clothing disposal. Automatic washing machines with integrated washing and drying functions can dry clothes directly after washing, eliminating the need for long drying times, which is particularly suitable for humid and rainy weather, and are therefore increasingly popular with consumers.

[0004] Many existing drying systems for clothing processing equipment use an evaporator to heat and absorb moisture from humid air in the inner tube of a washer / dryer, and then the resulting high-temperature air is re-entered into the inner tube of the washer / dryer to evaporate moisture from clothes. However, because the temperature of the entire evaporator is constant, the evaporator's moisture absorption capacity for humid air decreases as the humid air evaporates, resulting in low moisture absorption efficiency, long drying times, and high power consumption. Furthermore, while direct condensate rinse or a condenser may be used to dehumidify the humid airflow, the treated airflow still contains a lot of moisture, and recycling requires a cycle of "heating, cooling, dehumidifying, and reheating" on the airflow, resulting in low dehumidification efficiency and high power consumption.

[0005] Therefore, the existing drying assemblies are no longer able to meet the needs of consumers, and it is necessary to propose new drying structures and improve the structures of existing clothing processing devices. Summary of the Invention [Problem to be solved by the invention]

[0033] Next, exemplary embodiments of the present application will be described in more detail with reference to the accompanying drawings.

It should be understood that these embodiments are used so that this disclosure will be thorough and complete, and will fully convey the concept of these exemplary embodiments to those skilled in the art.

[0034] As shown in FIG. 1, the present application provides a clothing treatment device, which includes a housing 10, a drying module 20, and a drum 30. As shown in FIGS. 2 and 3, the drying module 20 includes a moisture-absorbing and dehumidifying member 203, a housing 206, and a heating module 208. The housing 206 includes a first housing 2061 and a second housing 2062, and the first housing 2061 and the second housing 2062 are sealed together to form a space for accommodating the moisture-absorbing and dehumidifying member 203. The moisture absorbing and dehumidifying member 203 rotates within a space formed by sealing and joining the first housing 2061 and the second housing 2062 to accommodate the moisture absorbing and dehumidifying member 203, and at least two partition members 2063 are provided at corresponding positions on the first housing 2061 and the second housing 2062, each substantially along the radial direction, and the at least two partition members 2063 divide the space into at least a moisture absorbing space 201 and a regeneration space 202 on a projection plane perpendicular to the rotation direction of the moisture absorbing and dehumidifying member 203, and the first housing 2061 has a first air flow inlet 2011 located close to the partition member, and the second housing 2062 has a first air flow outlet 2012 located close to another partition member, and the first air flow inlet 2011 and the first air flow outlet 2012 are adjacent to the at least two partition members, respectively, and are both located within the moisture absorbing space 201.

[0035] It should be noted that the partition members referred to herein are each separate partition assembly connected between the circumferential sidewall of the first housing 2061 or the second housing 2062 and an intermediate position of the housing, and it should be noted that the intermediate position is not necessarily a central position, so it should be understood that the partition members are not necessarily provided along the radial direction. The at least two partition members 2063 may both be integrally molded or may be manufactured and attached separately, and the manufacturing method does not affect the definition of a partition member.

[0036] The drum 30 has a drum air inlet and a drum air outlet, and is connected between the first air flow outlet 2012 of the housing 206 and the drum air inlet by an air supply duct 40 of the drum 30, and between the drum air outlet and the first air flow inlet 2011 of the housing 206 by an air outlet duct 50 of the drum 30.

[0037] Moisture absorbing and dehumidifying members 203 are provided in the moisture absorbing space 201 and the regenerating space 202, and the circulating airflow and the dehumidifying airflow flow through the moisture absorbing and dehumidifying member 203, respectively. The moisture absorbing and dehumidifying member 203 absorbs moisture from the circulating airflow in the moisture absorbing space 201 and expels the moisture through the dehumidifying airflow in the regenerating space 202. In the moisture absorbing space 201, a first moisture absorbing space and a second moisture absorbing space are formed on either side of the moisture absorbing and dehumidifying member 203, respectively. The first moisture absorbing space is a space having a first airflow humidity that has flowed in from the drum air outlet, and the second moisture absorbing space is a space having a second airflow humidity after moisture has been absorbed by the moisture absorbing and dehumidifying member 203, and the first airflow humidity is greater than the second airflow humidity. The moisture absorbing and dehumidifying member 203 is rotatably arranged in the space formed by the first housing 2061 and the second housing 2062, and at least a portion of the area on the moisture absorbing and dehumidifying member 203 periodically passes through the moisture absorbing space 201 and the regenerating space 202.

[0038] In one embodiment, a circulation fan 204 is provided in the gas passage where the moisture absorption space 201 is located to form a circulating airflow within the drum 30 and the moisture absorption space 201. A regeneration fan 205 is provided in the gas passage where the regeneration space 202 is located to form a dehumidifying airflow within the regeneration space 202.

[0039] In one embodiment, the regeneration space 202 is further provided with a heating module 208, which includes a hood 2081 and a heating assembly 2082 attached to the hood 2081. The heating module 208 is configured to be close to the regeneration space and adjacent to the moisture absorbing and dehumidifying member.

[0040] In addition, a rotating part 207 is further provided which is rotatably connected to the outer edge of the moisture absorbing and dehumidifying member 203, and a motor is provided inside the rotating part 207, which rotates the rotating part 207 and drives the moisture absorbing and dehumidifying member 203, which is rotatably connected to the rotating part 207, to rotate relative to the housing 206. In one embodiment, the rotation speed is 2 to 10 turns per minute. In specific applications, the clothing treatment device may further include components such as, but not limited to, a controller.

[0041] As shown by the arrows in Figure 4, when the circulation fan 204 is operating, a pressure difference is created on both sides of the circulation fan 204, creating a circulating airflow between the drum 30 and the absorption space 201. Moist air from within the drum 30 passes through the air outlet duct 50 and enters the absorption space 201 through the first air inlet 2011. As it passes through the moisture absorbing and dehumidifying member 203, water vapor in the circulating airflow is absorbed, and the high temperature of the turntable itself heats the circulating airflow, reducing its humidity and increasing its temperature. The processed, high-temperature, dry air is then discharged through the first air outlet 2012 of the absorption space 201 and through the air outlet duct 40 back into the drum 30. In this way, the air circulates within the drum 30 and the absorption space 201, and the clothes inside the drum 30 constantly exchange heat with the circulating airflow, removing residual moisture from the clothes and achieving the goal of drying the clothes. At the same time, the operation of the regeneration fan 205 creates a pressure difference on both sides of the regeneration fan 205, forming a dehumidifying flow in the regeneration space 202, and the air from the drum 30 enters the regeneration space 202 and flows through the moisture absorbing and dehumidifying member 203, removing moisture from the moisture absorbing and dehumidifying member 203 and reducing the moisture in the moisture absorbing and dehumidifying member 203, allowing the moisture absorbing and dehumidifying member 203 to maintain a high water absorption capacity and improve the dehumidification efficiency.

[0042] During the drying process, the continuous rotation of the moisture absorbing and dehumidifying member 203 causes at least a portion of the moisture absorbing and dehumidifying member 203 to dynamically and cyclically switch between the absorption space 201 and the regeneration space 202. The portion of the moisture absorbing and dehumidifying member 203 located in the absorption space 201 absorbs water vapor in the circulating airflow and uses its high temperature to heat the passing circulating airflow. This portion then rotates to the regeneration space 202, where the heating assembly 2082 heats it, allowing the moisture in this portion to be quickly desorbed. As a result, during the rotation of the moisture absorbing and dehumidifying member 203, the moisture absorbing and dehumidifying member 203 can continuously absorb and heat the circulating airflow in the absorption space 201 and continuously discharge the moisture absorbed by the moisture absorbing and dehumidifying member 203. As a result, the moisture absorbing and dehumidifying member 203 always has good moisture absorption ability and improves moisture absorption efficiency.

[0043] In this embodiment, the moisture absorbing and dehumidifying member 203 may have a disk-like structure with a certain thickness, and the thickness / diameter ratio is 1 / 80 to 1 / 4 to suit the overall mechanical structure of the clothing treatment device, and in one embodiment, the thickness / diameter ratio of the moisture absorbing and dehumidifying member 203 is 1 / 20 to 1 / 10 to improve the moisture absorption efficiency of the moisture absorbing and dehumidifying member 203. The moisture absorbing and dehumidifying member 203 may be made of any material with strong water absorption ability, such as zeolite, alkali metal silica aluminate, lithium chloride, silica gel, modified silica gel, or activated alumina.

[0044] Specifically, the hood 2081 is installed in the regeneration space 202, and the heating assembly 2082 is attached to the hood 2081 and may be a device with heating function such as an electric wire or a PTC heater. Depending on the performance of the moisture-absorbing and dehumidifying member 203 itself, the heating temperature of the heating assembly 2082 needs to be controlled within a certain range to achieve optimal regeneration performance of the moisture-absorbing and dehumidifying member 203. When the part rotates to the moisture-absorbing space 201, it is within the optimal moisture absorption temperature range. The edge of the hood 2081 is fixedly connected to the housing 206, so that the hood 2081 and the heating assembly 2082 do not rotate together during the rotation of the moisture-absorbing and dehumidifying member 203. At the same time, the hood 2081 is as close as possible to the moisture-absorbing and dehumidifying member 203, thereby heating the area of ​​the moisture-absorbing and dehumidifying member 203 that rotates until it is adjacent to the heating assembly 2082.

[0045] In one embodiment, the heating assembly 2082 alternates between a first heating power and a second heating power, where the first heating power is between 400 and 800W and the second heating power is between 1200 and 1600W. On the one hand, the first heating power is set to 400-800W to obtain a high temperature in the regeneration space 202 to heat the moisture absorbing and dehumidifying member 203 and improve the moisture desorption and regeneration efficiency of the moisture absorbing and dehumidifying member 203. On the other hand, the second heating power is set to 1200-1600W to prevent the temperature of the moisture absorbing and dehumidifying member 203 from being too high after passing through the regeneration space 202, rotating to the moisture absorbing space 201 and excessively heating the circulating airflow, which would cause the circulating airflow to enter the drum 30 and damage clothes, and the temperature of the moisture absorbing and dehumidifying member from being too high and affecting its moisture absorption efficiency. By setting the operating power of the heating assembly 2082 to alternate between the first heating power and the second heating power and limiting the range of the first heating power and the second heating power, higher regeneration efficiency is considered, the temperature of the circulating air when it enters the drum is controlled, and damage to clothes is prevented. In another embodiment, the heating assembly 2082 operates oscillating between a first heating power and a second heating power, such as a square wave, sine / cosine, or other periodic waveform, where the first heating power is between 400 and 800 W and the second heating power is between 1200 and 1600 W.

[0046] In this application, the entire drying process is divided into three stages: a start-up stage, a dehumidifying operation stage, and a cooling stage. The start-up stage refers to a stage in which the clothing treatment device starts each component, such as the circulation fan 204, the regeneration fan 205, the motor that drives the moisture absorption and dehumidification member 203 to rotate, and the heating assembly 2082, according to a user command. In the start-up stage, the controller controls the circulation fan 204, the regeneration fan 205, and the motor to start operating according to a drying command input by the user, the heating assembly 2082 starts to heat, and each parameter, such as the fan rotation speed and heating power, rises rapidly. The dehumidification operation stage refers to the stage in which the circulation fan 204, the regeneration fan 205 and the motor operate stably, and the heating assembly 2082 operates within the effective power range. After entering the dehumidification operation stage, the changes in each parameter such as the fan rotation speed and heating power tend to stabilize, the rotation speed of the moisture absorption and dehumidification member 203 may be set to a fixed value, and the operating power of the heating assembly 2082 alternates between a first heating power of 400-800W and a second heating power of 1200-1600W. The cooling phase refers to the phase in which the heating assembly 2082 stops operating, and the circulation fan 204, regeneration fan 205, and motor continue to operate until the clothes are cooled. When an inflection point is detected in the change of the drum temperature, the controller determines that the clothes are finished drying accordingly, closes the heating assembly, i.e., the drying process ends and enters the cooling phase, the circulation fan 204, regeneration fan 205, and motor continue to operate, the clothes in the drum 30 enter the cooling process, and each parameter such as the fan rotation speed is gradually returned to zero.

[0047] During the dehumidification operation phase, when the circulating airflow passes through the moisture absorbing and dehumidifying member 203, on the one hand, the moisture absorbing and dehumidifying member 203 utilizes its own water absorption properties to absorb the moisture in the circulating airflow and absorb the water vapor in the circulating airflow, resulting in a decrease in the humidity of the circulating airflow and at the same time releasing the latent heat of condensation in the water vapor, resulting in an increase in the temperature of the circulating airflow; on the other hand, after the moisture absorbing and dehumidifying member 203 rotates from the regeneration space 202 to the moisture absorbing space 201, it uses the high temperature it has obtained to heat the circulating airflow passing through, resulting in an increase in the temperature of the circulating airflow; in this way, after the circulating airflow passes through the moisture absorbing and dehumidifying member 203, the humidity decreases and the temperature increases, and a temperature difference within a certain range is formed between the first moisture absorbing space and the second moisture absorbing space.

[0048] In one embodiment, the clothing treatment device further includes a controller, wherein an air supply duct is provided between the first air flow outlet and the drum air inlet, a first temperature detection unit is provided in the air supply duct at a position close to the drum air inlet, and a second temperature detection unit is provided in the drum or air outlet duct at a position close to the drum air outlet, and based on the temperatures detected by the first temperature detection unit and the second temperature detection unit, the controller can control the power or rotation speed of the circulation fan 204, the regeneration fan 205, and the heating assembly 2082, respectively.

[0049] In this application, the thickness / diameter ratio of the moisture absorbing and dehumidifying member, the rotation speed of the moisture absorbing turntable, and the operating power of the heating assembly are limited within certain ranges, so that the first airflow temperature detected by the first temperature detection unit is substantially 70-80°C and the second airflow temperature detected by the second temperature detection unit is substantially 50-60°C during at least some dehumidifying operation stages. In one embodiment, the temperature difference between the first airflow temperature and the second airflow temperature is 25±5°C. Setting the first airflow temperature and the second airflow temperature within this temperature range not only saves power consumption, but also achieves a better drying effect, resulting in satisfactory hand feel and dryness of clothes washed at this temperature.

[0050] Furthermore, according to the inventor's research, if the temperature difference between the first and second moisture absorption spaces in the moisture absorption space 201 is stably kept within the range of 70 to 80°C during at least some of the dehumidification operation stages, the clothing treatment device can achieve good drying effect, and the feel and dryness of the clothes washed at that temperature will both be satisfactory.

[0051] In one embodiment, the difference in surface temperature between at least a portion of both sides of the moisture absorbing and dehumidifying member 203 in the moisture absorbing space 201 is 70 to 80°C during at least a portion of the dehumidifying operation period.

[0052] In one embodiment, during at least a portion of the dehumidifying operation period, the temperature difference between substantially symmetrical positions in the first moisture absorption space and the second moisture absorption space is 70 to 80°C, or the temperature difference between substantially symmetrical positions on both sides of the moisture absorption and dehumidification member 203 is 70 to 80°C.

[0053] In one embodiment, the moisture absorbing and dehumidifying member 203 rotates to pass through the regeneration space 202, the first airflow outlet 2012, and the first airflow inlet 2011 in sequence, and during at least a portion of the dehumidifying operation period, the temperature difference in the moisture absorbing space 201 between the first airflow outlet 2012 and the first airflow inlet 2011 is 70 to 80°C.

[0054] By doing so, a better drying effect can be obtained, and the feel and dryness of the clothes washed at that temperature will both be satisfactory.

[0055] Specific examples are further provided below. In each example, experiments are conducted under different parameter conditions to determine the temperature difference between the first and second moisture absorption spaces and the drying time based on the basic structural configuration of the laundry treatment device described above. The experimental conditions include: the weight of the laundry is approximately 4 kg; the thickness / diameter ratio of the moisture absorption and dehumidification member 203 is substantially limited to 1 / 20 to 1 / 10; the rotation speed of the moisture absorption and dehumidification member 203 is 2 to 10 rpm; and the first heating power of the heating assembly 2082 during the dehumidification operation phase is approximately 400 to 800 W and the second heating power is approximately 1200 to 1600 W. The temperature difference detection points may be set at substantially symmetrical positions between the first and second moisture absorption spaces, at substantially symmetrical positions on both sides of the moisture absorption and dehumidification member 203, or at the positions of the first airflow outlet 2012 and the first airflow inlet 2011. It should be noted that the weight of the laundry is merely a representation and is not an influencing parameter of the drying effect.

[0056] In addition, the regeneration performance and moisture absorption performance of the moisture absorbing and dehumidifying member 203 itself are affected by the heating temperature. If the temperature deviates from the optimum regeneration temperature range, the regeneration performance of the moisture absorbing and dehumidifying member 203 will decrease. At the same time, after that part of the moisture absorbing and dehumidifying member 203 rotates into the moisture absorption space 201, it will deviate from the optimum moisture absorption temperature range, and the moisture absorption performance of the moisture absorbing and dehumidifying member 203 will also decrease, which will affect the final drying efficiency of the clothes.

[0057] In Example 1, the thickness / diameter ratio of the moisture absorbing and dehumidifying member 203 was 25 mm / 320 mm = 0.0780, the rotation speed of the moisture absorbing and dehumidifying member 203 was 5 rpm, and the operating power of the heating assembly 2082 was a minimum of 600 W and a maximum of 1400 W. Experimental measurements showed that during the dehumidification operation phase, the actual temperature difference between the first moisture absorbing space and the second moisture absorbing space substantially varied within the range of 72.7 to 77.9°C, and the drying time was approximately 128 minutes.

[0058] In Example 2, the thickness / diameter ratio of moisture absorbing and dehumidifying member 203 was maintained at 25 mm / 320 mm = 0.0780, the operating power of heating assembly 2082 was unchanged at a minimum of 600 W and a maximum of 1400 W, and the rotation speed of moisture absorbing and dehumidifying member 203 was reduced to 3 rpm. Although the rotation speed of moisture absorbing and dehumidifying member 203 was slower than in Example 1 and the heating time as it passed through regeneration space 202 was longer, the temperature of the portion of moisture absorbing and dehumidifying member 203 passing through regeneration space 202 was essentially within the optimal regeneration temperature range, and this rotation speed did not significantly affect the moisture absorption efficiency of moisture absorbing and dehumidifying member 203. Experimental measurements showed that during the dehumidification operation phase, the actual temperature difference between the first and second moisture absorbing spaces substantially varied within a range of 72.9 to 78.6°C, and the drying time was approximately 130 minutes.

[0059] In Example 3, the thickness / diameter ratio of moisture absorbing and dehumidifying member 203 was maintained at 25 mm / 320 mm (0.0780), the operating power of heating assembly 2082 was unchanged at a minimum of 600 W and a maximum of 1400 W, and the rotation speed of moisture absorbing and dehumidifying member 203 was increased to 8 rpm. The rotation speed of moisture absorbing and dehumidifying member 203 was fast, but the increased rotation speed prevented moisture from being fully desorbed in the regeneration space, resulting in a certain loss in moisture absorption efficiency after moisture absorbing and dehumidifying member 203 rotated into moisture absorption space 201. At the same time, the heating time through regeneration space 202 was short, resulting in a loss in heating efficiency for the circulating airflow after rotation into moisture absorbing space 201. However, these efficiency losses were still within an acceptable range. Experimental measurements showed that during the dehumidification operation phase, the actual temperature difference between the first and second moisture absorbing spaces substantially varied between 70.3 and 76.2°C, and the drying time was approximately 133 minutes.

[0060] In Example 4, the thickness / diameter ratio of the moisture-absorbing and dehumidifying member 203 is maintained at 25 mm / 320 mm = 0.0780, the rotation speed of the moisture-absorbing and dehumidifying member 203 is unchanged at 5 rpm, and the operating power of the heating assembly 2082 is set to a minimum of 400 W and a maximum of 1200 W. At this time, the heating temperature of the moisture-absorbing and dehumidifying member 203 is low when it passes through the regeneration space 202, but is still within the optimal regeneration temperature range. When the moisture-absorbing and dehumidifying member 203 rotates into the moisture absorption space 201 to adsorb moisture, it is still within the optimal moisture absorption temperature range, so there is little impact on the regeneration efficiency and moisture absorption efficiency of the moisture-absorbing and dehumidifying member 203 itself. Although the heating efficiency of the circulating airflow decreases due to the decrease in temperature after the moisture-absorbing and dehumidifying member 203 passes through the moisture absorption space 201, the temperature of the circulating airflow is still controlled within the predetermined range, and there is little impact on the final drying efficiency. As can be seen from the experimental measurements, in the dehumidifying operation stage, the actual temperature difference between the first moisture absorption space and the second moisture absorption space varies substantially within the range of 70.2 to 75.6°C, and the drying time is about 136 minutes.

[0061] In Example 5, the thickness / diameter ratio of the moisture absorbing and dehumidifying member 203 is maintained at 25 mm / 320 mm = 0.0780, the rotation speed of the moisture absorbing and dehumidifying member 203 is unchanged at 5 rpm, and the operating power of the heating assembly 2082 is set to a minimum of 600 W and a maximum of 1600 W. At this time, the heating temperature of the moisture absorbing and dehumidifying member 203 when it passes through the regeneration space 202 is high but is still within the optimal regeneration temperature range, and when the moisture absorbing and dehumidifying member 203 rotates into the moisture absorption space 201 to adsorb moisture, it is still within the optimal moisture absorption temperature range, so there is little impact on the regeneration efficiency and moisture absorption efficiency of the moisture absorbing and dehumidifying member 203 itself. Although the heating efficiency of the circulating airflow is improved due to the temperature rise in the moisture absorption space 201, the temperature of the circulating airflow is still controlled within the preset range, and no damage is caused to the clothes. As can be seen from the experimental measurements, in the dehumidifying operation stage, the actual temperature difference between the first moisture absorption space and the second moisture absorption space varies substantially within the range of 73.7 to 79.5°C, and the drying time is about 130 minutes.

[0062] In Example 6, the rotation speed of the moisture-absorbing and dehumidifying member 203 is maintained at 5 rpm, the operating power of the heating assembly 2082 remains unchanged at a minimum power of 600 W and a maximum power of 1400 W, and the thickness / diameter ratio of the moisture-absorbing and dehumidifying member 203 is changed to 23 mm / 350 mm = 0.0657. In this case, the size of the moisture-absorbing and dehumidifying member 203 is increased, the heating power remains unchanged, and the temperature rise when the moisture-absorbing and dehumidifying member 203 passes through the regeneration space 202 is lower than in Example 1, but is still within the optimal regeneration temperature range. When the moisture-absorbing and dehumidifying member 203 rotates in the moisture absorption space 201 to adsorb moisture, it is still within the optimal moisture absorption temperature range. Therefore, there is little impact on the regeneration efficiency and moisture absorption efficiency of the moisture-absorbing and dehumidifying member 203 itself. The moisture absorption efficiency is improved due to the increased size of the moisture-absorbing and dehumidifying member 203, which basically offsets the impact on the drying efficiency caused by the reduced heating efficiency of the circulating airflow. As can be seen from the experimental measurements, in the dehumidifying operation stage, the actual temperature difference between the first moisture absorption space and the second moisture absorption space varies substantially within the range of 70.4 to 75.5°C, and the drying time is about 132 minutes.

[0063] In Example 7, the rotation speed of the moisture-absorbing and dehumidifying member 203 is maintained at 5 rpm, the operating power of the heating assembly 208 remains unchanged at a minimum of 600 W and a maximum of 1400 W, and the thickness / diameter ratio of the moisture-absorbing and dehumidifying member 203 is changed to 27 mm / 300 mm = 0.0900. In this case, the size of the moisture-absorbing and dehumidifying member 203 is reduced, the heating power remains unchanged, and the temperature rise when the moisture-absorbing and dehumidifying member 203 passes through the regeneration space 202 is higher than in Example 1, but is still within the optimal regeneration temperature range. When the moisture-absorbing and dehumidifying member 203 rotates in the moisture absorption space 201 to adsorb moisture, it is still within the optimal moisture absorption temperature range. Therefore, there is little impact on the regeneration efficiency and moisture absorption efficiency of the moisture-absorbing and dehumidifying member 203 itself. The reduced moisture absorption efficiency due to the reduced size of the moisture-absorbing and dehumidifying member 203 is basically offset by the impact on the drying efficiency caused by the improved heating efficiency of the circulating airflow. As can be seen from the experimental measurements, in the dehumidifying operation stage, the actual temperature difference between the first moisture absorption space and the second moisture absorption space varies substantially within the range of 74.5 to 79.2°C, and the drying time is about 133 minutes.

[0064] The overall data for Examples 1 to 7 above is shown in Table 1 below.

[0065] [Table 1]

[0066] In the comparative example of the present application, the regeneration temperature of the moisture absorbing and dehumidifying member 203 in the regeneration space 202 is increased or decreased by changing the thickness / diameter ratio of the moisture absorbing and dehumidifying member 203, the rotation speed, and the heating efficiency of the heating assembly 2082 outside the selected range. If the regeneration temperature is outside the optimal range, the regeneration performance of the moisture absorbing and dehumidifying member 203 itself will decrease, and at the same time, the moisture absorbing performance of that part of the moisture absorbing and dehumidifying member 203 will also decrease after it rotates into the moisture absorbing space 201, thereby affecting the final drying efficiency of the clothes. At the same time, the temperature increase or decrease of the moisture absorbing and dehumidifying member 203 in the moisture absorbing space 201 will cause a significant change in the heating efficiency of the circulating airflow, which will affect the final drying effect of the clothes. In the following Comparative Examples 1 to 6, the related parameters are adjusted outside the limited ranges, which has a large impact on the regeneration efficiency, moisture absorption efficiency, and heating efficiency of the circulating airflow of the moisture absorbing and dehumidifying member 203. During the dehumidification operation stage, the temperature difference between the first moisture absorption space and the second moisture absorption space 201 cannot be maintained within the range of 70 to 80°C. In this case, the clothes dry for a long time and the drying effect is poor, and in some cases the clothes may be damaged.

[0067] In Comparative Example 1, the thickness / diameter ratio of the moisture absorbing and dehumidifying member 203 was 25 mm / 320 mm=0.0780, the operating power of the heating assembly 2082 was set to a minimum of 600 W and a maximum of 1400 W, and the rotation speed of the moisture absorbing and dehumidifying member 203 was set to 1 rpm. At this time, the rotation speed was too slow, so the heating time in the regeneration space 202 was long, the temperature of the moisture absorbing and dehumidifying member 203 in the regeneration space 202 was higher than the optimal regeneration temperature range, and after a certain time had passed since the moisture absorbing and dehumidifying member 203 rotated into the moisture absorbing space 201, it was outside the optimal moisture absorption temperature range, and the regeneration efficiency and absorption efficiency of the moisture absorbing and dehumidifying member 203 itself were reduced. The humidity efficiency decreases, and furthermore, the heating efficiency of the circulating airflow passing through the moisture absorbing and dehumidifying member 203 also increases due to the temperature rise in the moisture absorbing space 201. As a result, the temperature of the heated circulating airflow after entering the drum 30 is too high, which may damage the clothes. In such a case, the dehumidification of the circulating airflow is insufficient and the heating is too high, so the temperature difference between the first moisture absorbing space and the second moisture absorbing space is higher than 70-80°C, and the drying time is longer. Experimental measurements have shown that during the dehumidifying operation stage, the actual temperature difference between the first moisture absorbing space and the second moisture absorbing space is substantially 83.5-90.9°C, and the drying time is approximately 162 minutes.

[0068] In Comparative Example 2, the thickness / diameter ratio of the moisture absorbing and dehumidifying member 203 was set to 25 mm / 320 mm=0.0780, the heating power of the heating assembly 2082 was set to a minimum of 600 W and a maximum of 1400 W, and the rotation speed of the moisture absorbing and dehumidifying member 203 was set to 12 rpm. Because the rotation speed was too fast, the heating time of the regeneration space 202 was too short, and the temperature of the moisture absorbing and dehumidifying member 203 in the regeneration space 202 was lower than the optimum regeneration temperature range. After the moisture absorbing and dehumidifying member 203 rotated into the moisture absorbing space 201, the temperature was outside the optimum regeneration temperature range. , the regeneration efficiency and moisture absorption efficiency of the moisture absorbing and dehumidifying member 203 itself decreases, and furthermore, the heating efficiency of the circulating airflow passing through the moisture absorbing and dehumidifying member 203 also decreases due to the drop in temperature of the moisture absorption space 201. In such cases, the dehumidification and heating of the circulating airflow is insufficient, the temperature difference between the first moisture absorption space and the second moisture absorption space is lower than the range of 70 to 80°C, and the drying time becomes longer. Experimental measurements have shown that during the dehumidification operation stage, the actual temperature difference between the first moisture absorption space and the second moisture absorption space is substantially 66.6 to 72.5°C, and the drying time is approximately 169 minutes.

[0069] In Comparative Example 3, the thickness / diameter ratio of the moisture absorbing and dehumidifying member 203 was set to 25 mm / 320 mm=0.0780, the rotation speed of the moisture absorbing and dehumidifying member 203 was set to 5 rpm, and the operating power of the heating assembly 2082 was set to a minimum of 200 W and a maximum of 1400 W. At this time, the heating temperature when the moisture absorbing and dehumidifying member 203 passed through the regeneration space 202 was low, and the temperature of the moisture absorbing and dehumidifying member 203 in the regeneration space 202 was lower than the optimal regeneration temperature range. After the moisture absorbing and dehumidifying member 203 rotated into the moisture absorbing space 201, the temperature rose to within the optimal moisture absorption temperature range. If the temperature is outside the range, the regeneration efficiency and moisture absorption efficiency of the moisture absorbing and dehumidifying member 203 itself will decrease, and further, the heating efficiency of the circulating airflow will decrease due to the temperature drop in the moisture absorption space 201. In such a case, the moisture absorbing and dehumidifying member 203 will not be able to dehumidify and heat the circulating airflow sufficiently, the temperature difference between the first moisture absorption space and the second moisture absorption space will be lower than the range of 70 to 80°C, and the drying time will be longer. Experimental measurements have shown that during the dehumidifying operation stage, the actual temperature difference between the first moisture absorption space and the second moisture absorption space is substantially 66.5 to 72.3°C, and the drying time is approximately 168 minutes.

[0070] In Comparative Example 4, the thickness / diameter ratio of the moisture absorbing and dehumidifying member 203 was set to 25 mm / 320 mm=0.0780, the rotation speed of the moisture absorbing and dehumidifying member 203 was set to 5 rpm, and the operating power of the heating assembly 2082 was set to a minimum of 600 W and a maximum of 2200 W. At this time, the heating temperature of the moisture absorbing and dehumidifying member 203 was high when it passed through the regeneration space 202, and the temperature of the moisture absorbing and dehumidifying member 203 in the regeneration space 202 was higher than the optimal regeneration temperature range. After the moisture absorbing and dehumidifying member 203 rotated into the moisture absorbing space 201, the temperature was outside the optimal moisture absorption temperature range for a portion of the time, and the regeneration efficiency and moisture absorption efficiency of the moisture absorbing and dehumidifying member 203 itself were low. The temperature of the circulating air decreases, and the heating efficiency of the circulating air improves due to the temperature rise in the moisture absorption space 201. However, the temperature of the heated circulating air after entering the drum 30 is too high, which can easily damage the clothes. In such cases, the circulating air is not dehumidified enough and is heated too much, so the temperature difference between the first and second moisture absorption spaces is higher than 70-80°C, which increases the drying time and the operating power of the clothing treatment device is high, resulting in increased power consumption. Experimental measurements have shown that during the dehumidification operation stage, the actual temperature difference between the first and second moisture absorption spaces is actually 79.6-92.8°C, and the drying time is approximately 171 minutes.

[0071] In Comparative Example 5, the rotation speed of the moisture absorbing and dehumidifying member 203 is set to 5 rpm, the operating power of the heating assembly 2082 is set to a minimum of 600 W and a maximum of 1400 W, and the thickness / diameter ratio of the moisture absorbing and dehumidifying member 203 is set to 18 mm / 400 mm=0.0450. At this time, the size of the moisture absorbing and dehumidifying member 203 is increased, the heating power is not changed, the temperature rise when the moisture absorbing and dehumidifying member 203 passes through the regeneration space 202 is small, the temperature of the moisture absorbing and dehumidifying member 203 in the regeneration space 202 is lower than the optimal regeneration temperature range, and the moisture absorbing and dehumidifying member 203 rotates in the moisture absorbing space 201 to adsorb moisture. When the temperature is lower than the optimum moisture absorption temperature range, the regeneration efficiency and moisture absorption efficiency of the moisture absorbing and dehumidifying member 203 itself decreases, and further, the heating efficiency of the circulating airflow decreases due to the temperature drop in the moisture absorption space 201. In such a case, the moisture absorbing and dehumidifying member 203 does not dehumidify and heat the circulating airflow sufficiently, the temperature difference between the first moisture absorption space and the second moisture absorption space is lower than the range of 70 to 80°C, and the drying time becomes longer. Experimental measurements have shown that during the dehumidification operation stage, the actual temperature difference between the first moisture absorption space and the second moisture absorption space is substantially 75.1 to 82.9°C, and the drying time is approximately 155 minutes.

[0072] In Comparative Example 6, the rotation speed of the moisture absorbing and dehumidifying member 203 was set to 5 rpm, the operating power of the heating assembly 2082 was set to a minimum of 600 W and a maximum of 1400 W, and the thickness / diameter ratio of the moisture absorbing and dehumidifying member 203 was set to 30 mm / 250 mm=0.1200. At this time, the size of the moisture absorbing and dehumidifying member 203 was reduced, the heating power was not changed, and the temperature rose significantly when the moisture absorbing and dehumidifying member 203 passed through the regeneration space 202. The temperature of the moisture absorbing and dehumidifying member 203 in the regeneration space 202 was higher than the optimal regeneration temperature range. When the moisture absorbing and dehumidifying member 203 rotated in the moisture absorbing space 201 to adsorb moisture, it was still higher than the optimal moisture absorption temperature range, and the moisture absorbing and dehumidifying member 203 itself The regeneration efficiency and moisture absorption efficiency of the body decrease, and the moisture absorption efficiency further decreases due to a decrease in the size of the moisture absorption and dehumidification member 203. Furthermore, the heating efficiency of the circulating airflow increases due to an increase in the temperature of the moisture absorption space 201, and the temperature of the heated circulating airflow after entering the drum 30 is too high, making it easy to damage the clothes. In such cases, the dehumidification of the circulating airflow is insufficient and the heating is too sufficient, so the temperature difference between the first moisture absorption space and the second moisture absorption space is higher than 70 to 80°C, and the drying time is longer. Experimental measurements have shown that during the main dehumidification operation stage, the actual temperature difference between the first moisture absorption space and the second moisture absorption space is substantially 77.1 to 89.6°C, and the drying time is approximately 159 minutes.

[0073] The optimum regeneration temperature and optimum moisture absorption temperature described in the above examples are merely temperatures at which the moisture absorption and regeneration efficiency is highest, and do not mean that regeneration and moisture absorption are not possible outside these temperature ranges.

[0074] The overall data for the above Comparative Examples 1 to 6 is shown in Table 2 below.
