The heating module 2500 covers the regeneration area of ​​the moisture absorbing and dehumidifying member 2200 (moisture absorbing and dehumidifying turntable 2201) and is used to heat the regeneration area of ​​the moisture absorbing and dehumidifying member 2200 (moisture absorbing and dehumidifying turntable 2201) and desorb moisture absorbed by the moisture absorbing and dehumidifying member 2200 (moisture absorbing and dehumidifying turntable 2201). The condensing module 2600 is used to condense the dehumidified stream flowing out from the regeneration area of ​​the moisture absorbing and dehumidifying member 2200 to dry the dehumidified stream.

[0072] According to some embodiments, drying apparatus 2000 further includes an upper housing and a lower housing that cover and secure the components of drying apparatus 2000, forming drying apparatus 2000 as an integrated module.

[0073] According to some embodiments, the upper and lower housings of drying apparatus 2000 may be separate housings corresponding to a single component of drying apparatus 2000, or may be integrated housings corresponding to multiple components of drying apparatus 2000. For example, in the embodiment shown in FIGS. 4 and 5, lower housing 2700 of drying apparatus 2000 is an integrated housing, and FIG. 6 shows a structural diagram of integrated lower housing 2700. As shown in FIG. 6, lower housing 2700 is provided with a mounting portion 2710 for mounting circulation fan 2100, a mounting portion 2720 (i.e., first mounting portion) for mounting moisture absorbing and dehumidifying member 2200, a mounting portion 2730 for mounting regenerative fan 2400, and a mounting portion 2740 for mounting condensation module 2600. The upper housing of drying apparatus 2000 is a separate housing and includes an upper housing 2810 for mounting circulation fan 2100, an upper housing 2820 for mounting moisture absorbing and dehumidifying member 2200, and an upper housing 2830 for mounting condensation module 2600.

[0074] According to some embodiments, as shown in Figures 3 to 5, a plurality of fourth mounting portions 2701 are provided on lower housing 2700 of drying device 2000, and a fifth mounting portion 2801 is provided on upper housing 2820. Fourth mounting portions 2701 and fifth mounting portions 2801 are fastened to housing 1200 of integrated washer-dryer washing machine 1000 with a wrap fastener, thereby realizing the mounting and fixing of the entire drying device 2000. In this embodiment, since there is no direct rigid connection between drying device 2000 and clothing storage device 1100, vibrations during the operation of clothing storage device 1100 are prevented from being transmitted to drying device 2000 (especially moisture absorbing and dehumidifying member 2200), thereby improving the stability and reliability of drying device 2000.

[0075] According to some embodiments, as shown in Figures 2 and 5, the first air outlet 2902 communicates with the air outlet duct 1300 of the clothing accommodation device 1100 via a flexible tube (e.g., a corrugated hose) 2903. According to some embodiments, the air outlet duct 1300 is provided with a filter (e.g., a filter mesh) for filtering out dust and clothing lint. Furthermore, the connecting member 1400 communicates with the air inlet duct of the clothing accommodation device 1100 via a flexible tube (not shown in Figures 2 and 5). This prevents vibrations from the clothing accommodation device 1100 from being transmitted to the drying device 2000 (especially the moisture absorbing and dehumidifying member 2200), improving the stability and reliability of the drying device 2000.

[0076] 4 and 5, the components of drying device 2000 (including circulation fan 2100, moisture absorption and dehumidification member 2200, moisture absorption and dehumidification turntable drive unit 2300, regeneration fan 2400, heating module 2500, condensation module 2600, etc.) are arranged horizontally, and the rotation axes of the rotating components (including circulation fan 2100, moisture absorption and dehumidification member 2200, moisture absorption and dehumidification turntable drive unit 2300, and regeneration fan 2400) are substantially parallel to and substantially perpendicular to the rotation axes of upper housing of combined washer-dryer washing machine 1000 and clothing storage device 1100. According to this embodiment, the height of combined washer-dryer washing machine 1000 can be minimized to save space.

[0077] Under the action of circulation fan 2100, a circulating airflow is formed between the moisture absorption passage and the inner cylinder. As shown in Figure 7, under the action of circulation fan 2100, the airflow in the inner cylinder passes through the inner cylinder's air outlet duct (with a built-in filter) and flexible tube 2903, and then enters first air outlet 2902, i.e., the air inlet of circulation fan 2100 (indicated by arrow A). The airflow flows out from the air outlet of circulation fan 2100 to the underside of moisture absorption and dehumidification turntable 2201 (indicated by arrow B), passes through moisture absorption and dehumidification turntable 2201, and reaches the upper side of moisture absorption and dehumidification turntable 2201 (indicated by arrow C), flows through the space above moisture absorption and dehumidification turntable 2201 (corresponding to the moisture absorption region) (indicated by arrow D), and enters the inner cylinder via first air inlet 2901 and connecting member 1400 (indicated by arrow E).

[0078] Under the action of the regeneration fan 2400, a dehumidified airflow is formed in the regeneration passage. As shown in FIG. 8, under the action of the regeneration fan 2400, the dehumidified airflow enters the air inlet of the regeneration fan 2400 (indicated by arrow A), passes through the regeneration fan 2400, and enters the heating module 2500 via the first connecting member 2909 (indicated by arrows B and C). The heating module 2500 is located above the regeneration area of ​​the moisture absorption and dehumidification turntable 2201. After entering the heating module 2500, the dehumidified airflow passes from top to bottom through the regeneration area of ​​the moisture absorption and dehumidification turntable 2201 (indicated by arrow D), and then enters the condensation module 2600 (indicated by arrow E). The air outlet of the housing (not shown in FIG. 8) of the condensation module 2600 communicates with the air inlet of the regeneration fan 2400 via the second connecting member 2910, forming a closed loop regeneration passage. The dehumidified air flow after condensation by condensing module 2600 flows again into the air inlet of regeneration fan 2400 via second connecting member 2910 (shown by arrow A), allowing the dehumidified air flow to circulate in the regeneration passage. The closed-loop regeneration passage prevents interaction between the dehumidified air flow and the external environment of the combined washer-dryer washing machine, thereby reducing any impact on the external environment (such as the impact on the humidity of the external air).

[0079] 9 and 10 show a three-dimensional view and an exploded view of the second connecting member 2910, respectively. FIG. 9 shows a schematic diagram of the fastening method between the condensation module 2600 and the lower housing 2700. As shown in FIG. 9, the upper housing 2830 of the condensation module is fitted with a mounting portion 2740 (i.e., the lower housing of the condensation module) for mounting the condensation module in the lower housing 2700. The condensation module upper housing 2830 covers the condensation module 2600 and presses the sealing strip 2920 around the condensation module 2600 downward, sealing and fixing it to the mounting portion 2740. The condensation module upper housing 2830 and the mounting portion 2740 form the complete housing of the condensation module 2600, i.e., the condensation module housing. A second air inlet 2633 is formed on the housing of the condensation module 2600, and the airflow heated by the heating module flows through the regeneration area of ​​the moisture absorption / dehumidification turntable 2201 and then enters the condensation module 2600 through the second air inlet 2633. A second air outlet 2631 is further formed on the housing of the condensation module 2600 , and the second air outlet 2631 is connected to the air inlet of the regenerative fan 2400 via a second connecting member 2910 .

[0080] Figure 10 shows a cross-sectional view of the condensation module housing 2630. As shown in Figure 10, the high-temperature, high-humidity dehumidified air flow that has passed through the regeneration area 2908 enters the condensation module housing 2630 through the second air inlet 2633 (indicated by arrow A), undergoes a drying process in the condensation module 2600 (not shown in Figure 10) (indicated by arrow B), and then flows out of the second air outlet 2631 to the second connecting member 2910 (indicated by arrow C).

[0081] 10 , a baffle plate 2632 is provided on the bottom surface of the condensation module housing 2630 near the second air outlet 2631. The baffle plate 2632 improves the condensation effect of the condensation module 2600, and ensures that the dehumidified airflow is sufficiently dried by the condensation module 2600. For example, the baffle plate 2632 can prevent the dehumidified airflow entering the condensation module housing 2630 from not passing through the condensation module 2600 but flowing out through the gap between the condensation module 2600 and the bottom surface of the condensation module housing 2630, which can prevent the airflow in this area from being condensed and dried.

[0082] As shown in Fig. 9, a condensed water pipe 2640 is provided for circulating condensed water in the condensation module 2600. The condensed water pipe 2640 further has a water inlet 2610 and a water outlet 2620. The direction indicated by arrow A in Fig. 9 is the flow direction of the dehumidified air in the condensation module 2600.

[0083] According to some embodiments, the condensate pipe 2640 may be provided with a sensor, such as a temperature sensor or a flow rate sensor, for detecting the status of the condensate. Alternatively, an inductive sensor may be provided on the outside of the condensate water inlet pipe for detecting whether the condensate is flowing through the condensate pipe 2640. Based on the status data detected by the sensor, the water flow in the condensate pipe 2640 may be adjusted or an alarm may be issued to ensure the normal operation of the condensation module 2600 and improve the condensation effect. For example, if the temperature sensor detects that the condensate temperature is too high, the current condensation effect is low. Therefore, the condensate flow rate may be increased to lower the condensate water temperature and improve the condensation effect. For example, if the flow rate sensor detects that the condensate flow rate is too low, the condensate pipe 2640 may be at risk of leaking. Therefore, an alarm may be issued to prompt the user to inspect or perform maintenance on the condensate pipe 2640. Of course, a temperature sensor may be provided at the air inlet and / or air outlet of the condensation module housing to detect whether the condensation module is operating normally based on the temperature detection value, the temperature detection difference value, or the temperature difference between the air inlet and the air outlet.

[0084] According to some embodiments, the condensate pipe 2640 may be a serpentine pipe, as shown in FIG. 9 . In the example of FIG. 9 , the condensate pipe 2640 is arranged in a serpentine shape in the condensing module 2600, thereby increasing the contact area between the dehumidified flow and the condensate pipe 2640 and ensuring sufficient condensation of the dehumidified flow. As shown in FIG. 9 , the condensing module 2600 has a first side and a second side that face each other in the flow direction of the dehumidified flow (see arrow A), with the first side located downstream of the second side. In one example (not shown), the water inlet 2610 and the water outlet 2620 of the condensate pipe 2640 are all located on a side wall of the condensing module 2600, which connects the first side and the second side of the condensing module 2600, with the water inlet 2610 and the water outlet 2620 being closer to the first side than to the second side. In this example, the condensed water pipe 2640 extends from the water inlet 2610 along a first zigzag path toward the second side of the condensing module 2600 to a location away from the first side, and then extends from there along a second zigzag path toward the first side to the water outlet 2620, the length of the first zigzag path being greater than the length of the second zigzag path, e.g., twice the length of the second zigzag path. This arrangement is advantageous because the temperature of the condensed water gradually increases from the first side of the condensing module 2600 to the second side due to heat dissipation by the dehumidified water stream, and conversely, the temperature of the condensed water gradually decreases from the second side of the condensing module 2600 to the first side due to heat absorption by the condensed water. This maintains a constant temperature difference between the dehumidified water stream and the condensed water during the condensation process, improving the condensation effect.

[0085] In some embodiments, drying apparatus 2000 includes a housing, such as an upper housing and a lower housing. The upper housing and the lower housing cover and secure the various components of drying apparatus 2000, forming drying apparatus 2000 as an integrated module. The housing includes a lower housing 2700 that houses moisture absorbing / dehumidifying turntable 2201, and an upper housing 2820. Two partition ribs, a lower housing first partition rib 2725-1 and a lower housing second partition rib 2725-2 shown in FIG. 6, are provided on lower housing 2700, and similarly, two partition ribs (not shown) are provided on upper housing 2820. A short shaft 2721 and a receiving portion for attaching short shaft 2721 are provided at the center of lower housing 2700, and one partition rib 2725-1 of lower housing 2700 is configured to extend from the inner circumferential wall of the housing to the housing receiving portion. Another partition rib 2725-2 of lower housing 2700 is set to extend from another position on the inner peripheral wall of the housing to the housing receiving portion. At least two of the partition ribs do not intersect with minor axis 2721, and therefore divide the internal space formed by docking lower housing 2700 and upper housing 2820 into two spaces, i.e., a first space and a second space, or a moisture absorption space and a regeneration space, or a moisture absorption region 2907 and a regeneration region 2908. The "first space" described above is understood to be a space formed by the partial inner walls of the lower housing 2700 and the upper housing 2820, the side walls facing the moisture absorption region of the first and second partition members, and the side walls facing the moisture absorption region 7 generated by the extended contact portions of the first and second partition members, and the "second space" is understood to be a space formed by another partial inner wall of the lower housing, the side walls facing the regeneration region of the first and second partition members, and a partial wall of the heating assembly 2500 described below. In some embodiments, the container is annular, and at least two partition ribs are provided tangentially to the outer periphery of the annular container.

[0086] At least one third partition member 2726 is further provided on first mounting portion 2720 of lower housing 2700. At least one third partition member 2726 divides moisture absorption region 2907 into at least two portions, first moisture absorption region 2907-1 and second moisture absorption region 2907-2, and can separate the circulating airflow flowing into moisture absorption region 2907. After entering the space between lower housing 2700 and moisture absorbing and dehumidifying member 2200 via the circulation fan, the circulating airflow is evenly divided into at least two portions (i.e., the airflow volume in each portion is substantially the same) by third partition member 2726. As a result, most of the circulating airflow flows around the circumference of moisture absorbing and dehumidifying member 2200 under the action of centrifugal force, with the airflow becoming smaller closer to the center. This embodiment improves the moisture absorption efficiency of moisture absorbing and dehumidifying member 2200 and achieves uniform and stable moisture absorption.

[0087] The housing in the above embodiment can accommodate a moisture absorbing and dehumidifying turntable 2201. The interior space of the housing is divided into at least a moisture absorbing space 2907 and a dehumidifying space 2908. When the moisture absorbing and dehumidifying turntable 2201 rotates into the moisture absorbing space 2907, it performs a moisture absorbing function. When the moisture absorbing and dehumidifying turntable 2201 rotates into the dehumidifying space 2908, it performs a dehumidifying function.

[0088] In one embodiment, the heating module 2500 covers at least a portion of the dehumidifying space 2908 and is used to heat the dehumidifying space 2908 or at least a portion of the moisture absorption / dehumidifying turntable 2201 located in the dehumidifying space 2908. The condensing module 2600 is provided downstream of the dehumidifying space 2908 and is used to condense the airflow exiting the dehumidifying space 2908.

[0089] The processing steps of the clothing processing device will be described below.

[0090] The garment processing device performs operations including one or more of a washing operation and a drying operation. The washing operation may include a washing stage, a rinsing stage, and a spin-drying stage. The washing stage may include a first wash and / or a second wash. The rinsing stage may include a first rinse and / or a second rinse (final rinse). The spin-drying stage may include a first spin (normal temperature spin) and / or a second spin (hot spin).

[0091] The drying operation may include a preheating step, a heat drying step, and a cooling step.

[0092] The preheating stage is used to heat the moisture absorption and dehumidification turntable 2201 in the drying module and improve the moisture absorption and dehumidification efficiency of the moisture absorption and dehumidification turntable 2201. When the moist airflow in the clothing storage device 1100 is circulated to the moisture absorption and dehumidification turntable 2201, it needs to be at a certain temperature to achieve moisture absorption and dehumidification. The preheating stage and the spinning stage may overlap, i.e., the preheating stage may start before the end of the spinning stage. If a second spinning run is performed, the heating module 2500 starts operating slightly earlier, and the preheating stage time is slightly shorter. In other words, if a second spinning run is performed, part of the heating process of the preheating stage is performed prior to the second spinning run.

[0093] The heat-drying stage is used to heat and dry the clothes in the clothing storage device 1100. The moist airflow in the clothing storage device 1100 continuously flows through the moisture-absorbing and dehumidifying turntable 2201, which absorbs moisture in the moist airflow and transports the dried airflow to the clothing storage device 1100 until the heat-drying is completed. During the heat-drying stage, the clothing treatment device is in a stable operation stage. Stable operation is primarily reflected by the difference between the temperature near the first airflow outlet (the temperature inside the clothing storage device 1100) and the temperature near the air inlet of the clothing storage device 1100 being within a stable change range. For example, in the clothing treatment device, the difference between the temperature near the first airflow outlet (or the temperature inside the clothing storage device 1100) and the temperature near the air inlet of the clothing storage device 1100 is within a temperature range of 18 to 30°C.

[0094] The temperature detection near the first airflow outlet may be set to detect one or more temperature points in the temperature field near the first airflow outlet. The temperature detection within the clothing containing apparatus 1100 may be set to detect one or more temperature points in the temperature field within the clothing containing apparatus 1100. The temperature detection near the air inlet of the clothing containing apparatus 1100 may be set to detect one or more temperature points in the temperature field near the first airflow outlet.

[0095] The cooling stage cools the clothes in the clothes containment apparatus 1100 to ensure that the clothes in the clothes containment apparatus 1100 have a proper removal temperature and that the dried clothes have a good hand feel.

[0096] In a drying operation, if the process of determining whether drying is complete is not accurate, the drying may be stopped early even though the clothes are wet, or the clothes may be heated to a high temperature and continue to dry even though they are already dry, causing irreversible damage to the clothes.

[0097] In one set of embodiments, the present application provides a method for controlling a garment treatment device, wherein the operation of the garment treatment device includes at least a drying operation, and the drying operation further includes a heating and drying stage and a cooling stage.

[0098] When the heating module 2500 in the drying device 2000 is in an operating state, it detects the temperature and / or humidity near the first airflow outlet. The operating power of the heating module 2500 may be dynamically adjusted or it may operate at a fixed power. When detecting the temperature and / or humidity near the first airflow outlet, a temperature sensor and / or a humidity sensor may be provided in the air outlet passage of the first airflow outlet (the sensor may be provided on the surface of the air outlet passage or embedded inside the air outlet passage).

[0099] When the temperature change rate near the first airflow outlet is greater than the first temperature change rate threshold and / or the humidity change rate near the first airflow outlet is less than the first humidity change rate threshold, the heating and drying stage is determined to be complete, the system transitions to the cooling stage, and the heating module 2500 in the drying device 2000 is turned off. In one embodiment, only the temperature near the first airflow outlet is detected, and the heating and drying stage is determined to be complete depending on whether the temperature change rate has reached the first temperature change rate threshold. In another embodiment, only the humidity near the first airflow outlet is detected, and the heating and drying stage is determined to be complete (whether to turn off the heating module 2500 in the drying device 2000) depending on whether the humidity change rate has reached the first humidity change rate threshold. In yet another embodiment, the temperature near the first airflow outlet and the humidity near the first airflow outlet are simultaneously detected, and the heating and drying stage is determined to be complete (whether to turn off the heating module 2500 in the drying device 2000) depending on whether the temperature change rate and humidity change rate have reached the first temperature change rate threshold and the first humidity change rate threshold, respectively.

[0100] In this embodiment, a method for determining whether the heating and drying stage is completed is provided, which can determine whether the heating and drying stage is completed more timely and accurately, turn off the heating module 2500 in a timely manner, avoid the occurrence of a situation where the heating module 2500 is stopped even though the clothes are not dry, and avoid irreversible damage to the clothes caused by excessive heating and drying.

[0101] In one embodiment, the temperature change rate and humidity change rate are calculated according to the following formulas: Temperature change rate = (current temperature - previous temperature) / time difference between two temperature measurements. Humidity change rate = (current humidity - previous humidity) / time difference between two humidity measurements.

[0102] Specifically, the temperature detected near the first airflow outlet is used to calculate the temperature change rate near the first airflow outlet, and the humidity detected near the first airflow outlet is used to calculate the humidity change rate near the first airflow outlet.

[0103] In this embodiment, the value ranges of the first temperature change rate threshold and the first humidity change rate threshold vary depending on the structural installation of the clothing treatment device. In one embodiment, the first temperature change rate threshold is set to 3°C / min. The first humidity change rate threshold is set to 5%RH / min. In another embodiment, the first temperature change rate threshold is set to 1°C / min to 6°C / min. The first humidity change rate threshold is set to 3%RH / min to 10%RH / min.

[0104] In one embodiment, after the heating module 2500 in the drying apparatus 2000 is turned off, the moisture absorption and dehumidification turntable driving unit 2300 continues to operate for a first period. When the heating and drying phase is completed, the heating module 2500 stops operating, but the moisture absorption and dehumidification turntable driving unit 2300 does not stop operating and continues to operate for the first period. The length of the first period may be set manually or may be set according to the specific circumstances of different drying operations, or the moisture absorption and dehumidification turntable driving unit 2300 may be turned off after the cooling phase is completed.

[0105] In this embodiment, when the heating and drying stage is completed, the operation of the heating module 2500 is stopped, allowing the drying apparatus 2000 to quickly transition to the cooling stage of the drying operation. Because the operation of the moisture absorption and dehumidification turntable driving unit 2300 is not stopped, the moisture absorption and dehumidification turntable 2201 continues to be driven to rotate, allowing the residual heat of the heating module 2500 to be quickly released, the high-temperature airflow to be quickly cooled, and the cooling stage time to be shortened.

[0106] In one embodiment, during the pre-heating stage, the moisture-absorbing and dehumidifying turntable 2201 is first activated before the heating module 2500 is started, thereby allowing the moisture-absorbing and dehumidifying turntable 2201 to be heated more evenly and preventing the heating module 2500 from heating a certain position on the moisture-absorbing and dehumidifying turntable 2201 for a long period of time, which could cause drying burns.

[0107] In one embodiment, once the baking stage is complete, the circulation fan 2100 continues to operate and the regeneration fan 2400 continues to operate at a higher power.

[0108] In this embodiment, when the heating and drying stage is completed, the circulation fan 2100 for forming a circulating airflow passing between the moisture absorption areas of the clothing storage device 1100 and the drying device 2000 continues to operate, thereby realizing airflow circulation between the clothing storage device 1100 and the drying device 2000 and accelerating the cooling rate of the clothing in the clothing storage device 1100. On the other hand, the regeneration fan 2400 for forming a regeneration airflow passing through the dehumidification space operates at a higher power to transport more dry regeneration airflow to the dehumidification space and carry and discharge the high-temperature humid airflow generated in the dehumidification space, thereby accelerating the cooling rate of the clothing in the clothing storage device 1100. The inlet air of the regeneration fan 2400 can come from the atmosphere or the condensation module 2600.

[0109] In one embodiment, if the temperature near the first airflow outlet is equal to or greater than a first abnormal temperature value, it is determined that the drying operation is abnormal and an alarm signal for the drying operation abnormality is issued. For example, the normal temperature near the first airflow outlet may be set to 53±5°C (e.g., 50°C, 53°C, 55°C, 57°C, or 58°C), and the first abnormal temperature value may be set to 60°C. The normal temperature near the first airflow outlet is a temperature point in the cross-sectional temperature field where the first airflow outlet is located.

[0110] This embodiment provides a method for determining abnormalities in the drying operation, and the abnormalities in the drying operation may be abnormalities in the pre-heating stage, the heating and drying stage, or the cooling stage. When the condensation module 2600, the regeneration fan 2400, the filter wire clogged, or the water film on the filter wire occurs in the laundry treatment device, the temperature near the first airflow outlet may be greater than the first abnormal temperature value (60°C).

[0111] In one embodiment, the condensing module 2600 has a second air inlet and a second air outlet. The airflow exiting the dehumidifying space 2908 enters the condensing module 2600 through the second air inlet, is condensed by the condensing module 2600, and then enters the heating module 2500 through the second air outlet. The drying operation further includes detecting the temperature near the second air inlet. When the temperature near the second air inlet reaches a first temperature threshold, the heating and drying stage is terminated. The first temperature threshold is the normal temperature near the second air inlet during the drying operation and is typically set to 70±5°C. The first temperature threshold may be set to a temperature value such as 68°C, 69°C, 72°C, or 73°C. When the temperature near the second air inlet is equal to or greater than a second abnormal temperature value, the drying operation is determined to be abnormal. The second abnormal temperature value may be set to 100°C. That is, when the temperature near the second air inlet is equal to or greater than 100°C, the drying operation is determined to be abnormal, and an alarm signal for the drying operation abnormality is issued. The drying operation abnormality may be a pre-heating stage abnormality, a heating and drying stage abnormality, or a cooling stage abnormality. If the condensation module 2600, the regeneration fan 2400, the filter wire clogged, or the filter wire water film occurs in the clothes treatment device, it may lead to a situation where the temperature near the second air inlet exceeds the second abnormal temperature value (100°C).

[0112] In one embodiment, the drying operation further includes detecting the temperature near the second air outlet, and turning off the heating module 2500 when the temperature near the second air inlet reaches a second temperature threshold. The second temperature threshold is the temperature near the second air outlet when the drying device 2000 is operating normally, and is typically set to 60°C ± 5°C. If the temperature near the second air outlet is equal to or greater than a third abnormal temperature value, it is determined that the drying operation is abnormal, and an alarm signal for the drying operation abnormality is issued. The third abnormal temperature value may be set to 90°C.

[0113] The drying operation abnormality may be a pre-heating stage abnormality, a heating and drying stage abnormality, or a cooling stage abnormality. If the condensation module 2600, the regeneration fan 2400, the filter wire clogged, or the filter wire water film occurs in the clothes treatment device, it may lead to a situation where the temperature near the second air inlet exceeds the second abnormal temperature value (100°C).

[0114] In this embodiment, whether the heating and drying stage is completed is determined depending on whether the temperature near the second air outlet reaches the second temperature threshold, and thus whether to turn off the heating module 2500 is determined. In this embodiment, whether the temperature near the second air outlet is equal to or greater than the third abnormal temperature value is determined to issue an alarm signal for the abnormal drying operation. Whether the temperature near the second air outlet is equal to or greater than the third abnormal temperature value can be detected, and the detection result can be fed back to the control system of the garment processing device in a timely manner. The control system of the garment processing device prompts the user to quickly check whether each structural component of the drying device 2000 is faulty.

[0115] In one embodiment, during a drying operation, if the temperature near the first air flow inlet is less than a preset minimum temperature near the first air flow inlet, the operating power of the heating module 2500 is controlled to be increased, and if the temperature near the first air flow inlet is equal to or greater than a preset maximum temperature near the first air flow inlet, the operating power of the heating module 2500 is controlled to be decreased.

[0116] This embodiment provides a dynamic heating method during a drying operation. The preset minimum temperature near the first air inlet may be set to 60°C to 70°C, and the preset maximum temperature near the first air inlet may be set to 75°C to 80°C. For example, in one embodiment, if the temperature near the first air inlet is lower than the preset minimum temperature near the first air inlet, 65°C, the operating power of the heating module 2500 is controlled to be increased. If the temperature near the first air inlet is equal to or higher than the preset maximum temperature near the first air inlet, 78°C, the operating power of the heating module 2500 is controlled to be decreased.

[0117] In one embodiment, the heating and drying step includes controlling the heating module 2500 to vary within a preset heating power range to control the temperature near the first air inlet within a preset temperature range. In one embodiment, the heating module 2500 varies within a preset heating power range of 400 W to 1600 W. In one embodiment, the heating module 2500 varies within a preset heating power range of 600 W to 1400 W to control the temperature near the first air inlet within a preset temperature range of 60°C to 80°C. In one embodiment, the temperature near the first air inlet is within a preset temperature range of 70°C to 75°C. In this embodiment, the heating module 2500 may operate between 600 W and 1400 W in the form of a sine wave, square wave, sawtooth wave, etc.

[0118] In one embodiment, the preset heating power is between a first preset heating power and a second preset heating power, and the heating module 2500 varies between the first heating power and the second heating power in a square wave pattern. In one embodiment, the first heating power is between 400W and 800W, and the second preset heating power is between 1200W and 1600W.

[0119] For example, in one embodiment, the heating module 2500 operates at an operating power of 580 W for a certain period of time, and if the temperature near the first air flow inlet is lower than a preset minimum temperature value of 63°C near the first air flow inlet, the operating power of the heating module 2500 is controlled to increase, for example, to operate at 1300 W for a certain period of time. If the temperature near the first air flow inlet is equal to or higher than a preset maximum temperature value of 75°C near the first air flow inlet, the operating power of the heating module 2500 is controlled to decrease, for example, to continue operating at 580 W for a certain period of time. In this embodiment, the heating module 2500 operates at 580 W for a certain period of time, at 1300 W for a certain period of time, and at 580 W for a certain period of time, and these three operating times may or may not be equal.

[0120] In one embodiment, during the heating and drying stage, the heating module 2500 is controlled to operate variably within a preset power range of 400 W to 1600 W. In another embodiment, the heating module 2500 varies according to a square wave within a preset heating power range of 600 W to 1400 W. The maximum value of the square wave is 1400 W, and the minimum value of the square wave is 600 W. The square wave may be a square wave with a regular period or a square wave with an irregular period.

[0121] In the above-described embodiment involving adjusting the heating power for operation of the heating module 2500, the temperature near the first airflow inlet is maintained at a constant level of 60°C to 80°C as much as possible (in some embodiments, the temperature near the first airflow inlet is maintained at 70°C to 75°C as much as possible), while the moisture absorbing and dehumidifying turntable 2201 in the regeneration area has high regeneration efficiency. Specifically, when the heating module 2500 operates at a high heating power (e.g., 1400 W), the temperature of the moisture absorbing and dehumidifying turntable 2201 in the regeneration area and the temperature of the dehumidifying stream can be increased, thereby achieving high regeneration efficiency of the moisture absorbing and dehumidifying turntable 2201 in the regeneration area. When the heating module 2500 operates at a low heating power (e.g., 600 W), the temperature of the moisture absorbing and dehumidifying turntable 2201 in the regeneration area and the temperature of the dehumidifying stream can be decreased, while the regeneration efficiency of the moisture absorbing and dehumidifying turntable 2201 in the regeneration area can be reduced to some extent (however, the regeneration efficiency can be maintained within a certain range and the regeneration efficiency will not be significantly reduced). The heating module 2500 can vary between high and low heating power to maintain the temperature within the clothing storage device 1100 or the temperature near the first air flow inlet throughout the drying operation while balancing the regeneration efficiency of the moisture absorption and dehumidification turntable 2201.

[0122] In one embodiment, the garment treatment device includes at least a garment storage apparatus 1100, a drying apparatus 2000, a drum inlet conduit, a first temperature detection unit, and a control module. The heating module 2500 is electrically connected to the control module. The first temperature detection unit is located in the drum inlet conduit near the air inlet and is used to detect the temperature of the airflow entering the garment storage apparatus 1100 and transmit the temperature to the control module. The drum inlet conduit (i.e., the air inlet duct of the garment storage apparatus 1100) connects the air outlet (first air outlet 2902 shown in FIG. 5 ) located in the housing with the air inlet (first airflow inlet) of the garment storage apparatus.

[0123] The operation process of the garment treatment device includes at least a drying operation, and during the drying operation, the heating module 2500 operates within a preset heating power range, and the control module adjusts the operating power of the heating module 2500 based on the data of the first temperature detection unit.

[0124] In one embodiment, the heating module 2500 includes at least two temperature sensors. The at least two temperature sensors are used to detect the temperature of the airflow entering the clothing containment device 1100. The first temperature sensor is used to detect whether the temperature of the airflow entering the clothing containment device 1100 reaches 180°C. The second temperature sensor is used to detect whether the temperature of the airflow entering the clothing containment device 1100 reaches 200°C. When the temperature of the airflow entering the clothing containment device 1100 reaches 180°C, an alarm signal indicating an abnormal drying operation is issued and the heating module 2500 is shut down. When the temperature of the airflow entering the clothing containment device 1100 reaches 200°C, the power is cut off.

[0125] In one embodiment, the control module adjusting the operating power of the heating module 2500 based on data from the first temperature detection unit includes: if the first temperature detection unit detects that the temperature of the airflow entering the clothing storage device 1100 is lower than the drum inlet temperature minimum value, the control module controls the operating power of the heating module 2500 to increase.

[0126] If the first temperature detection unit detects that the temperature of the airflow entering the clothing storage apparatus 1100 is greater than the drum inlet temperature maximum value, the control module controls the heating module 2500 to reduce its operating power.

[0127] In one embodiment, the minimum drum inlet temperature is 60°C to 70°C, and may be set, for example, at 63°C, 65°C, 67°C, 68°C, 69°C, or 70°C. The maximum drum inlet temperature is 75°C to 80°C, and may be set, for example, at 75°C, 76°C, 78°C, 79°C, or 80°C.

[0128] In one embodiment, the regeneration fan 2400 and circulation fan 2100 are maintained to operate at constant power during the drying operation.

[0129] In one embodiment, the cooling phase includes the following steps: controlling the heating module 2500 to stop heating; controlling the power of the circulation fan 2100 and / or the regeneration fan 2400 to increase; and determining that the cooling phase has ended when the temperature near the first airflow inlet is lower than a fourth temperature threshold and / or when the temperature near the first airflow outlet is lower than a fifth temperature threshold, and controlling the circulation fan 2100 and / or the regeneration fan 2400 to stop operating. The fourth temperature threshold may be set to 50°C to 65°C. For example, the fourth temperature threshold may be set to 53°C, 58°C, 62°C, or 65°C. The temperature near the first airflow inlet may be understood as the temperature at any position in the temperature field near the air inlet. In this embodiment, since heating and drying are no longer required during the cooling phase, the heating module 2500 is controlled to stop heating. Since further cooling is required at this time, the circulation fan 2100 and the regeneration fan 2400 operate at increased power. In this embodiment, when the temperature near the first air inlet is lower than the fourth temperature threshold, it is determined in time whether the cooling stage is completed, so as to save the power consumption required for the device operation.

[0130] In one embodiment, the cooling phase includes controlling the heating module 2500 to stop heating and controlling the power of the circulation fan 2100 and / or the power of the regeneration fan 2400 to increase. The cooling phase is determined to be complete when the temperature near the first airflow outlet is lower than a fifth temperature threshold. The fifth temperature threshold may be normal temperature or may vary with the seasons. For example, the fifth temperature threshold may be set to 5-15°C in spring and autumn, 15-35°C in summer, and 0-10°C in winter. The specific fifth temperature threshold may be preset or may be continuously adjusted during operation. The fifth temperature threshold may be adjusted to an optimal temperature value to accurately determine whether the cooling phase is complete and achieve the goal of reducing power consumption required for device operation.

[0131] In the above-mentioned optional embodiment, when it is determined that the cooling stage has ended, the operation of the circulation fan 2100 and the regeneration fan 2400 is controlled to stop. At this time, if the drying operation has ended and there is no other operation, the entire machine of the clothing treatment device may be turned off.

[0132] In one set of embodiments, the present application provides a method for controlling a clothes treatment device, the operation of which includes a spin-drying stage.

[0133] The spin-drying stage includes at least a first spin. After the first spin is completed, the weight of the clothes in the clothes storage device 1100 is obtained. It is determined whether the weight is less than a preset weight threshold. If the weight is less than the preset weight threshold, a second spin is not performed. Existing clothes drying devices may have a second spin (heat spin) process, but the procedure / capacity of the heat spin is fixed, and it is not possible to intelligently select whether heat spin is necessary in the current process. In this embodiment, a step for determining the weight of the clothes after the first heat spin is completed is provided. If the weight is less than the preset weight threshold, a second spin is not performed. This shortens the clothes processing time and saves some energy while ensuring effective clothes processing.

[0134] If the weight is equal to or greater than the preset weight threshold, a second spin cycle is performed, and the heating module 2500 is turned on before the second spin cycle. In this step, the second spin cycle is a thermal spin cycle, and the temperatures throughout the second spin cycle are not equal. In one embodiment, the second spin cycle may be set to begin after the temperature inside the clothing storage device 1100 or the temperature near the first airflow outlet reaches a preset temperature. In another embodiment, the heating module 2500 may be turned on after the first spin cycle is completed, i.e., the second spin cycle is performed.

[0135] In one embodiment, during the first spin cycle and / or the second spin cycle, the operating stages of the clothing storage device 1100 include at least the following: an operating stage of a first operating power (eccentric) and an operating stage of a second operating power (main spin cycle), where the first operating power is less than the second operating power, where the first operating power and the second operating power are the driving power of the inner cylinder, i.e., the driving power of the inner cylinder drive motor.

[0136] If the second spin-drying is not performed, the heating module 2500 is controlled to operate at the first heating power after the operation phase at the second operating power of the first spin-drying is completed.

[0137] In this embodiment, controlling the heating module 2500 to operate at the first heating power may be considered as a second dehydration (thermal dehydration) step or as part of a preheating stage during a drying operation, and turning on the heating module 2500 during the dehydration stage can save time required for drying. The specific first heating power may be the maximum heating power of the heating module 2500.

[0138] In one embodiment, when a second spin cycle is performed, the heating module 2500 is controlled to operate at the second heating power after the second operating power phase of the first spin cycle is completed. The second spin cycle is performed after the temperature inside the clothing storage device 1100 or the temperature at the first airflow outlet reaches the sixth temperature threshold. The second heating power may be smaller than the first heating power, for example, 1000 W, 1100 W, or another power value. The second heating power may be equal to the first heating power, for example, 1200 W, 1600 W. For example, both the second heating power and the first heating power are increased at full power, and after a certain temperature is reached, the power of the heating module 2500 is reduced.

[0139] In one embodiment, when the temperature inside the clothing containing apparatus 1100 or the temperature near the first airflow outlet reaches a sixth temperature threshold, the heating module 2500 is controlled to operate at a third heating power and the control motor of the clothing containing apparatus 1100 is controlled to operate at a second operating power (the second operating power is greater than the first operating power), and the third heating power is less than the second heating power. The sixth temperature threshold may be set to 45°C±5°C.

[0140] In this embodiment, on the one hand, when the temperature inside the clothing storage device 1100 or the temperature near the first air flow outlet reaches the sixth temperature threshold, the efficiency of thermal dehydration is high, and on the other hand, by the second operating power being high and the heating power being appropriately reduced (the third heating power is smaller than the second heating power), the operating power of the entire clothing storage device can be ensured and the service life of the clothing storage device can be extended.

[0141] In one embodiment, after the second operating power stage of the second spin-drying is completed, the heating module 2500 is controlled to operate at a fourth heating power, which is greater than the third heating power. In this embodiment, the fourth heating power may be the full power of the heating module 2500, and the heating module 2500 operates at a higher heating power, thereby shortening the time for the pre-heating stage during the drying operation.

[0142] In one embodiment, at least the regenerative fan 2400 and / or the moisture absorption and dehumidification turntable driving unit 2300 are controlled to start before the operation of the heating module 2500. Alternatively, at least the regenerative fan 2400 and / or the moisture absorption and dehumidification turntable driving unit 2300 are controlled to start before the power of the heating module 2500 reaches a first threshold power. Alternatively, at least the regenerative fan 2400 and / or the moisture absorption and dehumidification turntable driving unit 2300 are controlled to start before the heating module 2500 is activated for a first preset time. Alternatively, at least the regenerative fan 2400 and / or the moisture absorption and dehumidification turntable driving unit 2300 are controlled to start before the turntable temperature of the moisture absorption and dehumidification turntable 2201 reaches a third temperature threshold. The first threshold power may be set to 400W to 800W. The first threshold power is equal to or less than the low power of the heating module 2500 during normal operation (in the above embodiment, the heating module 2500 varies within a preset heating power range of 400W to 1600W, and here, the first threshold power may be equal to or less than the minimum power value within the preset heating power range). The first preset time is equal to or less than the time it takes for the heating power to reach the first threshold power. For example, the first preset time may be set to 10 to 20 minutes, e.g., 15 minutes. The third temperature threshold is equal to or less than 180°C. The third temperature threshold is equal to or less than 180°C.

[0143] In this embodiment, three activation timings are provided for the regenerative fan 2400 and / or the moisture absorption and dehumidification turntable driving unit 2300, and the determination methods for these three activation timings can be applied to different clothing treatment devices. Specifically, by controlling at least the regenerative fan 2400 and / or the moisture absorption and dehumidification turntable driving unit 2300 to start before the operation of the heating module 2500, it is possible to prevent the heating module 2500 from heating the fixed position of the moisture absorption and dehumidification turntable 2201, thereby reducing damage to the moisture absorption and dehumidification turntable 2201 and extending the service life of the moisture absorption and dehumidification turntable 2201. By controlling the regeneration fan 2400 and / or the moisture absorbing and dehumidifying turntable driving unit 2300 to start before the power of the heating module 2500 reaches the first threshold power or before the heating module 2500 is activated for the first preset time, and by controlling the regeneration fan 2400 and / or the moisture absorbing and dehumidifying turntable driving unit 2300 to start before the turntable temperature of the moisture absorbing and dehumidifying turntable 2201 reaches the third temperature threshold, the moisture absorbing and dehumidifying turntable 2201 can have a constant temperature and improve the pre-heating effect of the pre-heating stage of the drying operation.

[0144] In one set of embodiments, the present application further provides a method of controlling a garment treatment device, wherein the operation of the garment treatment device includes a drying operation, the drying operation including a heat drying stage and a cooling stage.

[0145] The cooling stage operation includes at least the following: S1: Stopping heating of heating module 2500, and controlling so as not to stop the operation of circulation fan 2100 and / or regeneration fan 2400 and / or moisture absorption and dehumidification turntable drive unit 2300. S2: Detecting the temperature near the first air flow inlet and the temperature near the first air flow outlet. S3: When the temperature near the first air flow inlet is lower than the fourth temperature threshold and / or the temperature near the first air flow outlet is lower than the fifth temperature threshold, controlling so as to stop the operation of circulation fan 2100, regeneration fan 2400, and moisture absorption and dehumidification turntable drive unit 2300.

[0146] In this embodiment, when the temperature near the first air inlet is lower than the fourth temperature threshold and / or the temperature near the first air outlet is lower than the fifth temperature threshold, it is determined that the cooling phase has ended, and the circulation fan 2100, the regeneration fan 2400, and the moisture absorption / dehumidification turntable driving unit 2300 are controlled to stop operating. The fourth temperature threshold may be set to 50 to 65°C, for example, 55°C, 58°C, 60°C, 63°C, or 65°C. The fifth temperature threshold may be normal temperature or may vary with the seasons. For example, the fifth temperature threshold may be set to 5 to 15°C in spring and autumn, 15 to 35°C in summer, and 0 to 10°C in winter.

[0147] In this embodiment, when the temperature near the first airflow inlet is lower than the fourth temperature threshold, or the temperature near the first airflow outlet is lower than the fifth temperature threshold, or the temperature values ​​near the first airflow inlet and near the first airflow outlet simultaneously reach the corresponding threshold temperatures, it is determined that the cooling phase has ended, and the circulation fan 2100, the regeneration fan 2400, and the moisture absorption and dehumidification turntable drive unit 2300 are controlled to stop operating.

[0148] In one embodiment, in step S1, the power of the circulation fan 2100 is controlled to be increased to a third circulation power and / or the power of the regeneration fan 2400 is controlled to be increased to a third regeneration power. In this embodiment, the third circulation power and the third regeneration power are both maximum powers. For example, the third circulation power may be set in the range of 80 W to 90 W. The third regeneration power may be set in the range of 20 W to 30 W. In one embodiment, the circulation fan 2100 is operated at a power increased to 90 W and / or the regeneration fan 2400 is operated at a power increased to 30 W.

[0149] In one set of embodiments, the present application further provides a method for controlling a clothes treatment device, the operation of which includes a washing operation and a drying operation.

[0150] The heating module 2500 is controlled to be activated before the washing operation is completed, or before the drying operation is started, and the heating module 2500 is controlled to be variably operated within a preset heating power range at least at a stage after the washing operation is completed.

[0151] In this embodiment, by activating the heating module 2500 before the end of the washing operation, the clothing storage device 1100 can be preheated early, thereby shortening the time for the subsequent drying operation, particularly the preheating stage of the drying operation. In at least one stage after the end of the washing operation (e.g., the heating stage of the drying operation), the heating module 2500 is controlled to operate variably within a preset heating power range (e.g., the preset heating power range is 400 W to 1600 W). In other stages after the end of the washing operation (e.g., the preheating stage of the drying operation), the heating module 2500 operates primarily at a stable heating power, and if it is detected that a temperature abnormality exists in another component or that a certain temperature threshold has been reached, the heating module 2500's heating power is controlled to be reduced.

[0152] In one embodiment, before starting operation of the heating module 2500, the regeneration fan 2400 and / or the moisture absorption / dehumidification turntable drive unit 2300 are controlled to start first, thereby preventing the heating module 2500 from continuously heating a certain portion of the moisture absorption / dehumidification turntable 2201.

[0153] In one embodiment, at least the regenerative fan 2400 and / or the moisture absorption and dehumidification turntable driving unit 2300 are controlled to start before the operation of the heating module 2500. Alternatively, at least the regenerative fan 2400 and / or the moisture absorption and dehumidification turntable driving unit 2300 are controlled to start before the power of the heating module 2500 reaches a first threshold power. Alternatively, at least the regenerative fan 2400 and / or the moisture absorption and dehumidification turntable driving unit 2300 are controlled to start before the heating module 2500 is activated for a first preset time. Alternatively, at least the regenerative fan 2400 and / or the moisture absorption and dehumidification turntable driving unit 2300 are controlled to start before the turntable temperature of the moisture absorption and dehumidification turntable 2201 reaches a third temperature threshold.

[0154] In this embodiment, four timings are provided for the regenerative fan 2400 and / or the moisture absorption / dehumidification turntable driving unit 2300, and the determination method for these four activation timings can be applied to different clothing treatment devices or different clothing treatment processes of the same clothing treatment device. For details, please refer to the description of the above embodiment.

[0155] In one set of embodiments, the present application further provides a method for controlling a garment treatment device, wherein the operation of the garment treatment device includes a drying operation, the drying operation including a preheating stage, a heat drying stage, and a cooling stage.

[0156] The pre-heating stage operations include at least the following: S10: The moisture absorbing / dehumidifying turntable driving unit 2300 is started, and in the preheating stage, the moisture absorbing / dehumidifying turntable 2201 is rotated at the first rotation speed.

[0157] S11: The heating module 2500 is activated to heat the moisture absorption / dehumidification turntable 2201 or the dehumidification space.

[0158] S12: Controlling to start the regeneration fan 2400 before the power of the heating module 2500 reaches the first threshold power, or before the heating module 2500 is activated for the first preset time, or before the temperature of the dehumidification space reaches the third temperature threshold. In this embodiment, the pre-heating stage of the drying operation is as follows: first, the moisture absorption and dehumidification turntable 2201 is activated, then the heating module 2500 is activated, and finally the regenerative fan 2400 is activated. By activating the moisture absorption and dehumidification turntable 2201 first, it is possible to prevent the moisture absorption and dehumidification turntable 2201 from being heated in a fixed position. By activating the regenerative fan 2400 before the three situations in S12 occur, on the one hand, the heat generated by the heating module 2500 can be sufficiently circulated within the clothing storage device 1100 to heat the clothes, and on the other hand, the actual power consumption of the device can be reduced, saving energy.

[0159] In one set of embodiments, the present application further provides a method for controlling a clothes treatment device, wherein the operation of the clothes treatment device includes a drying operation.

[0160] The drying operation includes a preheating stage, a heat drying stage and a cooling stage.

[0161] S20: Start the regeneration fan 2400. S21: Start the heating module 2500 to heat the moisture absorbing and dehumidifying turntable 2201 or the dehumidifying space. S22: Control to start the moisture absorbing and dehumidifying turntable 2201 before the power of the heating module 2500 reaches the first threshold power, before the heating module 2500 has been activated for the first preset time, or before the temperature of the dehumidifying space reaches the third temperature threshold.

[0162] In this embodiment, in the pre-heating stage of the drying operation, the regeneration fan 2400 is first activated, then the heating module 2500 is activated, and finally the moisture absorption and dehumidification turntable 2201 is activated. By first activating the regeneration fan 2400, a regeneration airflow can be formed in the dehumidification space of the moisture absorption and dehumidification turntable 2201. Next, by activating the heating module 2500, the regeneration airflow can be used to circulate the heat generated by the heating module 2500, preventing the moisture absorption and dehumidification turntable 2201 from being heated in a fixed position.

[0163] In one set of embodiments, the present application further provides a method for controlling a garment treatment device, wherein the operation of the garment treatment device includes a drying operation, the drying operation including a preheating stage, a heat drying stage, and a cooling stage.

[0164] S30: Activate the heating module 2500 to heat the moisture absorbing and dehumidifying turntable 2201. S31: Before the power of the heating module 2500 reaches the first threshold power, or before the heating module 2500 has been activated for the first preset time, or before the temperature of the dehumidifying space reaches the third temperature threshold, activate the moisture absorbing and dehumidifying turntable 2201 and control the regenerative fan 2400 to start.

[0165] In this embodiment, the pre-heating stage of the drying operation is as follows: first, the heating module 2500 is activated, then the moisture absorption and dehumidification turntable 2201 is activated, and finally the regeneration fan 2400 is activated. By first activating the heating module 2500, the moisture absorption and dehumidification turntable 2201 is activated before any one of the three situations in S31 occurs (before the first situation occurs).

[0166] In the above three sets of embodiments, the third temperature threshold may be set to 160 to 180°C, for example, 162°C, 167°C, 172°C, 175°C, or 180°C. The first rotation speed is 8 to 15 rpm. During the heating and drying stage, the rotation speed of the moisture absorption and dehumidification turntable 2201 is reduced. In one embodiment, the moisture absorption and dehumidification turntable 2201 rotates at a second rotation speed. The second rotation speed is 2 to 8 rpm, and in different embodiments, the second rotation speed may be set to 4 rpm, 5 rpm, 6 rpm, or 7 rpm.

[0167] In one set of embodiments, the present application provides a method for controlling a garment treatment device, wherein the operation of the garment treatment device includes a drying operation, the drying operation including a preheating stage, a heat drying stage, and a cooling stage.

[0168] In the pre-heating stage, the heating module 2500 is activated and operates. Specifically, the heating module 2500 operates at maximum power immediately after activation, and when it detects that the temperature inside the clothing storage device 1100 or the temperature near the first airflow outlet has reached the sixth temperature threshold (45°C), the heating module 2500 is controlled to reduce its heating power. On the one hand, this allows the system temperature of the drying device 2000 to be appropriately adjusted, and on the other hand, it allows the moisture absorption and dehumidification turntable 2201 to be protected, and prevents a certain position on the moisture absorption and dehumidification turntable 2201 from being burned due to high temperatures.

[0169] During the heating and drying stage, the heating module 2500 fluctuates within a preset heating power range (400W to 1600W). During the pre-heating stage, the heating power of the heating module 2500 is equal to or less than the maximum power value within the preset heating power range. The preset heating power range may be set to 600W to 1400W. The heating module 2500 fluctuates according to different waveforms within the preset heating power range. During the fluctuating heating, if it is detected that the temperature inside the clothing storage device 1100 or the temperature threshold temperature near the first airflow outlet has reached the sixth temperature threshold, the heating module 2500 operates with reduced power. During the cooling stage, the operation of the heating module 2500 is controlled to stop.

[0170] In this embodiment, it is provided that the heating module 2500 operates at different powers at different stages of the drying operation in order to obtain the highest drying efficiency within the shortest time of the drying operation.

[0171] In one embodiment, during the pre-heating stage, the regenerative fan 2400 operates at a first regenerative power. During the heating and drying stage, the regenerative fan 2400 operates at a second regenerative power. During the cooling stage, the regenerative fan 2400 operates at a third regenerative power, where the first regenerative power is less than or equal to the second regenerative power and may be zero. The third regenerative power is greater than the first regenerative power and greater than or equal to the second regenerative power.

[0172] In this embodiment, the second regenerative power may be a fixed power or a variable power, and the magnitude of the second regenerative power may change in a positive correlation with the fluctuation of the heating module 2500. A positive correlation change is understood to mean that the heating power and the regenerative power have a positive correlation in their increasing and decreasing change trends, with a certain delay in their change time. For example, the heating power increases for a certain period of time, followed by an increase in the regenerative power. The regenerative fan 2400 is designed to operate at different regenerative powers in different stages to improve the drying efficiency of the clothing treatment device.

[0173] In one embodiment, in the preheating stage, the moisture absorption and dehumidification turntable driving unit 2300 rotates at a first rotation speed. In the heating and drying stage, the moisture absorption and dehumidification turntable driving unit 2300 rotates at a second rotation speed. In the cooling stage, the moisture absorption and dehumidification turntable driving unit 2300 rotates at a third rotation speed. Here, the first rotation speed, the second rotation speed, and the third rotation speed are equal to each other. Alternatively, the first rotation speed and the third rotation speed are equal to or greater than the second rotation speed. The second rotation speed may be set to 2 to 10 rpm, and in one embodiment, may be set to 4 to 6 rpm.

[0174] In this embodiment, the rotation speeds of the moisture absorbing and dehumidifying turntable driving unit 2300 are set to be equal, or the first rotation speed and the third rotation speed are set to be equal to or greater than the second rotation speed, so that the moisture absorbing and dehumidifying turntable 2201 rotates at an appropriate rotation speed, thereby improving the dehumidification efficiency of the moisture absorbing and dehumidifying turntable 2201.

[0175] In one embodiment, during the pre-heating stage, the circulation fan 2100 operates at a first circulation power. During the heating and drying stage, the circulation fan 2100 operates at a second circulation power. During the cooling stage, the circulation fan 2100 operates at a third circulation power, where the first circulation power and the third circulation power are equal to or greater than the second circulation power. The second circulation power may be a fixed power or a dynamically changing power, and the magnitude of the second circulation power changes in accordance with the power change of the heating module 2500, i.e., changes in a positive correlation with the change in the heating power of the heating module 2500.

[0176] In this embodiment, the circulation fan 2100 has a heating power that matches that of the heating module 2500 during the heating and drying stage, and a rotation speed that matches that of the moisture absorption and dehumidification turntable driving unit 2300, thereby improving the drying efficiency of the drying device 2000.

[0177] In one embodiment, the drying apparatus 2000 further includes a condensation module 2600 disposed on the other side of the dehumidifying space and used to condense the airflow exiting the dehumidifying space. The condensation module 2600 is a water-cooled condenser. During at least one stage of the operation of the garment treatment device, the water flow rate is 0.2 to 0.4 L / min. In one embodiment, during the heating and cooling stages of the drying operation, the water flow rate is set to 0.36 L / min.

[0178] In one set of embodiments, the present application provides a method for controlling a garment treatment device. The garment treatment device includes a garment storage apparatus 1100 and a drying apparatus 2000. The operation of the garment treatment device includes a drying operation. The drying operation includes a preheating stage, a heating and drying stage, and a cooling stage.

[0179] At the start of the pre-heating stage, the heating module 2500 is activated and operates, and if it is detected that the temperature inside the clothing storage device 1100 or the temperature threshold temperature near the first airflow outlet has reached a sixth temperature threshold (which may be set to 45°C), the heating module 2500 is controlled to operate at a reduced heating power. The regenerative fan 2400 operates at a first regenerative power. The moisture absorption / dehumidification turntable driver 2300 rotates at a first rotation speed. The circulation fan 2100 operates at a first circulation power.

[0180] During the heating and drying stage, the heating module 2500 fluctuates within a preset heating power range. The regenerative fan 2400 operates at a second regenerative power, or the regenerative fan 2400 changes in a positive correlation with changes in the heating power of the heating module 2500, the second regenerative power being greater than the first regenerative power. The moisture absorption / dehumidification turntable driver 2300 rotates at a second rotation speed, which is less than or equal to the first rotation speed. The circulation fan 2100 operates at a second circulation power, or the circulation fan 2100 changes in a positive correlation with changes in the heating power of the heating module 2500, the second circulation power being less than or equal to the first circulation power.

[0181] During the cooling phase, the operation of the heating module 2500 is controlled to stop. The regeneration fan 2400 operates at a third regeneration power, which is greater than the second regeneration power and greater than the first regeneration power. The moisture absorption / dehumidification turntable driver 2300 rotates at a third rotation speed, which is equal to or greater than the second rotation speed. The circulation fan 2100 operates at a third circulation power, which is greater than the second circulation power.

For the specific values ​​of each parameter in this embodiment, please refer to the description of any one of the above embodiments.

[0183] 13, in a preliminary heating stage, the heating module first operates at a heating power of 1400 W for a first period of time, and when the temperature inside the clothing storage device 1100 or the temperature near the first air outlet reaches a sixth temperature threshold (45°C ± 5°C), the heating power of the heating module is reduced to operate at a heating power of 600 W. In the heating and drying stage, the heating module fluctuates in heating power between 600 W and 1400 W. In the cooling stage, the heating module stops operating (operating power is 0).

[0184] During the first stage of the pre-heating phase, the inner cylinder drive motor operates at a rotational speed of 40 to 100 rpm. When the heating power of the heating module 2500 decreases (when the temperature inside the clothing storage device 1100 or the temperature near the first air outlet reaches the sixth temperature threshold of 45°C ± 5°C), the inner cylinder drive motor increases its rotational speed and operates at a maximum rotational speed of 1400 rpm (the process in which the inner cylinder drive motor operates at a high rotational speed is the second spin-drying process). During the heating and drying phases and cooling phases, the inner cylinder drive motor operates at a rotational speed of 40 to 100 rpm.

[0185] In the preheating stage, the heating and drying stage, and the cooling stage, the moisture absorbing and dehumidifying turntable driving unit 2300 drives the moisture absorbing and dehumidifying turntable 2201 to operate at a rotation speed of 2 to 10 rpm.

[0186] During the preheating and heating / drying stages, the operating power of the circulation fan is set in the range of 30-90 W, and the rotation speed of the circulation fan is set to 3800 rpm-4000 rpm. During the cooling stage, the circulation fan operates at a rotation speed of 4000 rpm-5600 rpm.

[0187] During the preheating and heating / drying stages, the operating power of the regeneration fan is set in the range of 10 to 30 W, and the rotation speed of the regeneration fan is set to 3700 rpm to 3900 rpm. During the cooling stage, the rotation speed of the regeneration fan is 3900 rpm to 4100 rpm.

[0188] In the above specific embodiment, the most important heating and drying stage during the drying operation can be 100 to 110 minutes, thereby shortening the drying time and improving the drying efficiency.
