[0045] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention, as detailed in the appended claims.

[0046] The present embodiment is described in detail below with reference to the accompanying drawings. The following embodiments and examples may be combined with each other unless there is any conflict.

[0047] According to an exemplary embodiment, Figure 2 and Figure 3 As shown, this embodiment proposes a multi-drum laundry processing device with a drying function, which includes multiple laundry processing drums 1, a drying duct, and a heating module 5, wherein each laundry processing drum 1 is provided with an air inlet and an air outlet. The drying duct includes a main drying duct 6, multiple first sub-ducts 2, and multiple second sub-ducts 3. The air outlet ends of the multiple first sub-ducts 2 are respectively connected to the air inlets of the multiple laundry processing drums 1 in a one-to-one correspondence, and the air inlet ends of the multiple second sub-ducts 3 are respectively connected to the air outlets of the multiple laundry processing drums 1 in a one-to-one correspondence; the air inlet ends of the multiple first sub-ducts 2 are respectively connected to the air outlets of the main drying duct 6, and the air outlet ends of the multiple second sub-ducts 3 are respectively connected to the air inlet of the main drying duct 6. It should be noted that the air inlet and the air outlet are relative to the clothes processing drum 1. The air flow in the clothes processing drum 1 enters the second sub-duct 3 from the air outlet, is heated by the heating module 5 in the second sub-duct 3, enters the first sub-duct 2 through the air outlet end of the heating module 5, and finally enters the clothes processing drum 1 from the first sub-duct 2 through the air inlet. The air flow direction is referenced to FIG. Figure 2 and Figure 3In the direction indicated by the arrow. The heating module 5 is arranged on the main drying air duct 6, and the main drying air duct 6 is controlled to be selectively connected with at least one first sub-air duct 2 and at least one second sub-air duct 3 to provide drying airflow to at least one clothing processing drum 1. The heating module 5 is, for example, a heat pump drying module, which includes a refrigerant circulation loop formed by a compressor, a condenser, a throttling device and an evaporator connected in sequence, wherein the air inlet end of the heating module 5 is located on the side of the evaporator away from the condenser, and the air outlet end of the heating module 5 is located on the side of the condenser away from the evaporator. The drying air duct also includes a plurality of fans (not shown in the figure), and the plurality of fans are arranged in a one-to-one correspondence with the plurality of first sub-air ducts 2, or the plurality of fans are arranged in a one-to-one correspondence with the plurality of second sub-air ducts 3. The multi-drum clothing processing device of this embodiment shares a heating module 5, and the heating module 5 can be controlled to be selectively connected with at least one first sub-air duct 2 and at least one second sub-air duct 3 to provide drying airflow to at least one clothing processing drum 1, thereby realizing partial drying or simultaneous drying of multiple clothing processing drums 1.

[0048] The multi-drum clothing processing device of this embodiment includes an auxiliary processing module 4, which may include at least one of an auxiliary heating device, an auxiliary deodorizing device, an auxiliary fragrance enhancing device, an auxiliary steam care device, or an auxiliary disinfection device. In one example, the clothing processing device includes an auxiliary processing module 4, which is arranged between the air inlet end of multiple first sub-air ducts 2 and the air outlet end of the main drying air duct 6. The auxiliary processing module 4 can be controlled to communicate with at least one first sub-air duct 2 to perform auxiliary processing on the clothing to be processed in the clothing processing drum 1 to which it is connected according to the needs of the clothing to be processed. At this time, a damper mechanism can be provided between the auxiliary processing module 4 and the multiple first sub-air ducts 2 to enable the air flow processed by the auxiliary processing module 4 to flow to the target clothing processing drum 1. In a feasible embodiment, the damper mechanism includes an air distribution shell and an air distribution piece. A cylindrical air distribution cavity is formed in the air distribution shell. A plurality of branch air ports are spaced apart along the side walls of the cylindrical cavity in the circumferential direction. The plurality of branch air ports are connected one-to-one with the plurality of first sub-air ducts 2. The main air port is arranged relative to the side walls of the cylindrical cavity in the axial direction. The main air port is connected with the main drying air duct 6. The air distribution piece is rotatably arranged on the side walls of the cylindrical air distribution cavity in the axial direction. The air distribution piece is constructed to be able to open at least one of the plurality of branch air ports.

[0049] In another example, the multi-drum clothing processing device further includes a plurality of auxiliary processing modules 4, and the plurality of auxiliary processing modules 4 are provided in a one-to-one correspondence with the plurality of first sub-air ducts 2. The auxiliary processing modules 4 can be controlled to perform auxiliary processing on the clothing to be processed in accordance with the requirements of the clothing to be processed in the clothing processing drum to which they are connected. When the clothing processing drum 1 is running in the drying mode, the corresponding auxiliary processing device 41 can be turned on according to the clothing processing requirements of the clothing to be processed in the clothing processing drum 1, such as the deodorization requirement, the fragrance enhancement requirement, the steam care requirement or the sterilization requirement. At the same time, when multiple clothing processing drums 1 are running in the drying mode at the same time, the corresponding auxiliary processing device 41 can also be selected to be turned on according to the different clothing processing requirements of different clothing processing drums 1, so as to achieve different clothing processing effects for different clothing processing drums 1, thereby improving the user experience.

[0050] In some embodiments, as Figure 3 As shown, the auxiliary processing module 4 includes at least an auxiliary heating device, which is controlled to perform auxiliary heating on the drying airflow entering the clothing processing drum 1 when the air inlet temperature of the clothing processing drum 1 is lower than its target drying temperature. The auxiliary heating device is, for example, an electric heating device. When multiple clothing processing drums 1 are drying simultaneously, the auxiliary heating device can, based on the different drying temperature requirements of the multiple clothing processing drums 1, perform temperature compensation on the drying airflow generated by the heating module 5 through the auxiliary heating device when the multiple clothing processing drums 1 share a heating module 5, thereby meeting the different drying temperature requirements of different clothing processing drums 1. At the same time, it can also compensate for the slow heating of the heat pump heating module 5 in the early stage of heating, accelerate the drying temperature without damaging the clothes, and shorten the drying time.

[0051] In some embodiments, as Figure 3As shown, each first sub-duct 2 includes multiple independent branch ducts 21, each of which is connected to the air outlet of the main drying duct 6. Each auxiliary processing module 4 includes multiple auxiliary processing devices 41 with different clothing processing functions. The multiple auxiliary processing devices 41 are arranged in the multiple branch ducts 21. The passages between the multiple branch ducts 21 and the air outlet of the main drying duct 6 can be controlled to be partially or fully connected. When the same clothing processing drum 1 has multiple clothing processing requirements, the auxiliary processing devices 41 corresponding to the multiple clothing processing requirements can be opened, and the passages between the branch ducts 21 corresponding to the auxiliary processing devices 41 and the air outlet of the main drying duct 6 can be connected. For example, when the same clothing processing drum 1 is simultaneously required to have auxiliary heating treatment and fragrance treatment, the auxiliary heating device and the fragrance treatment device can be started, and the branch air duct 21 provided with the auxiliary heating device and the fragrance treatment device can be connected to the passage at the air outlet end of the main drying air duct 6. Under the action of the fan, the drying airflow generated by the heating module 5 enters the branch air duct 21 provided with the auxiliary heating device and the fragrance treatment device respectively, and enters the corresponding clothing processing drum 1 after auxiliary heating treatment and auxiliary fragrance treatment.

[0052] When different laundry processing drums 1 have different laundry processing requirements, the auxiliary treatment devices 41 corresponding to the laundry processing requirements of the corresponding laundry processing drum 1 can be turned on, and the branch air duct 21 corresponding to the auxiliary treatment device 41 can be connected to the air outlet end of the main drying air duct 6. For example, when the multiple laundry processing drums 1 include a first laundry processing drum and a second laundry processing drum, and the first laundry processing drum and the second laundry processing drum are simultaneously running a drying program, and the first laundry processing drum also has an additional fragrance addition requirement and the second laundry processing drum also has an additional deodorization requirement, the fragrance addition device corresponding to the first treatment drum can be turned on, the deodorization device corresponding to the second laundry processing drum can be turned on, and the branch air duct 21 provided for the auxiliary fragrance addition device and the auxiliary deodorization device can be connected to the air outlet end of the main drying air duct 6. Under the action of the fan, the drying airflow generated by the heating module 5 enters the fragrance addition device of the first laundry processing drum and the branch air duct 21 provided for the deodorization device of the second laundry processing drum, respectively, and enters the corresponding laundry processing drum 1 after fragrance addition and deodorization treatment.

[0053] In some embodiments, the number of branch air ducts 21 is less than or equal to the number of auxiliary treatment devices 41. That is, at least one auxiliary treatment device 41 may be installed in the same branch air duct 21. In one example, the plurality of auxiliary treatment devices 41 include an auxiliary heating device, an auxiliary aroma device, and an auxiliary heat deodorization device. The auxiliary heating device and the auxiliary aroma device or the auxiliary deodorization device may be installed in the same branch air duct 21, thereby reducing the number of branch air ducts 21.

[0054] In some embodiments (not shown in this example figure), the multi-drum laundry processing apparatus further includes a damper mechanism disposed between the air inlet ends of the multiple branch air ducts 21 and the air outlet end of the main drying air duct 6. The damper mechanism is configured to connect one or more of the multiple branch air ducts 21 to the main drying air duct 6, thereby enabling the drying airflow entering the same laundry processing drum 1 to undergo auxiliary treatment via one or more auxiliary treatment devices 41, thereby achieving a variety of laundry processing effects. Furthermore, the drying airflow entering different laundry processing drums 1 can also undergo auxiliary treatment via the same or different auxiliary treatment devices 41, thereby achieving the same or different laundry processing effects. In a feasible embodiment, the damper mechanism includes an air distribution shell and an air distribution piece. A cylindrical air distribution cavity is formed in the air distribution shell. A plurality of branch air ports are spaced apart along the side wall in the circumferential direction of the cylindrical cavity. The plurality of branch air ports are connected one-to-one with a plurality of branch air ducts 21. The main air port is arranged relative to the side wall in the axial direction of the cylindrical cavity. The main air port is connected with the main drying air duct 6. The air distribution piece is rotatably arranged on the side wall in the axial direction of the cylindrical air distribution cavity. The air distribution piece is constructed to be able to open at least one of the plurality of branch air ports.

[0055] According to an exemplary embodiment, this embodiment provides a drying method for a multi-drum laundry processing device, and the drying method is applicable to any of the multi-drum laundry processing devices with a drying function. Figure 4 is a flow chart of a drying method of a multi-drum laundry processing apparatus according to an exemplary embodiment. Figure 4 , the drying method comprises the following steps:

[0056] S41. When at least one laundry processing drum is running in a drying mode, determining laundry processing information of at least one laundry processing drum;

[0057] S42: Control the auxiliary processing module to start according to the clothing processing information to perform auxiliary processing on the drying airflow passing into the at least one clothing processing drum.

[0058] In this embodiment, the clothing processing information includes clothing information, such as at least one of the clothing drying temperature standard, clothing wrinkle information, and clothing odor information. According to the clothing drying temperature standard, the heating program of the heating module and the target heating temperature can be determined, and according to the clothing wrinkle information, the clothing wrinkle level can be determined to determine whether steam care is required for the clothing, and according to the clothing odor information, whether deodorization or fragrance enhancement is required, etc. can be determined. In one example, the clothing processing information is determined based on the acquired clothing information, and the clothing information is, for example, clothing material information and / or clothing type information. In another example, the clothing processing information is determined based on the drying mode selected by the user. For example, the user selects the drying mode based on the control panel of the clothing processing device or the smart terminal bound to the clothing processing device. The drying mode is, for example, at least one of the low-temperature drying mode, the high-temperature drying mode, the fragrance enhancement & drying mode, the deodorization & drying mode, or the steam care & drying mode.

[0059] In some embodiments, the auxiliary processing module is controlled to start according to the clothing processing information to perform auxiliary processing on the drying airflow entering at least one clothing processing drum, including: determining the auxiliary processing device corresponding to the clothing processing information, connecting the branch air duct set by the auxiliary processing device corresponding to the clothing processing information and the main drying air duct 6, controlling the heating module to start, and controlling the auxiliary processing device corresponding to the clothing processing information to start.

[0060] Figure 5 is a flow chart of a drying method of a multi-drum laundry processing apparatus according to an exemplary embodiment. Figure 5 The plurality of laundry processing drums include a first laundry processing drum and a second laundry processing drum, and the drying method includes the following steps:

[0061] S51: When the first laundry processing drum is in a drying mode, determining whether the second laundry processing drum is in a drying mode;

[0062] S52. When the second laundry processing drum is not running in drying mode, control the heating module to run the heating program according to the drying temperature standard of the first laundry processing drum; when the second laundry processing drum is running in drying mode, determine the heating program of the heating module according to the drying temperature standards of the first laundry processing drum and the second laundry processing drum.

[0063] Wherein: the heating program of the heating module is determined according to the drying temperature standards of the first clothing processing drum and the second clothing processing drum, including: when the drying temperature standard of the first clothing processing drum is greater than or equal to the drying temperature standard of the second clothing processing drum, controlling the heating module to maintain the current heating program; when the drying temperature standard of the first clothing processing drum is less than the drying temperature standard of the second clothing processing drum, controlling the heating module to run the heating program according to the drying temperature standard of the first clothing processing drum.

[0064] The drying method of this embodiment further includes: when the first laundry processing drum and the second laundry processing drum are simultaneously operating in a heating mode, obtaining a first inlet air temperature of the first laundry processing drum and a second inlet air temperature of the second laundry processing drum; comparing the first inlet air temperature with the first target drying temperature of the first laundry processing drum and comparing the second inlet air temperature with the second target drying temperature of the second laundry processing drum; controlling the auxiliary heating device corresponding to the first laundry processing drum to start when the first inlet air temperature is less than the first target drying temperature; controlling the auxiliary heating device corresponding to the first laundry processing drum to stop heating when the first inlet air temperature is greater than or equal to the first target drying temperature; controlling the auxiliary heating device corresponding to the second laundry processing drum to start when the second inlet air temperature is less than the second target drying temperature; and controlling the auxiliary heating device corresponding to the second laundry processing drum to stop heating when the second inlet air temperature is greater than or equal to the second target drying temperature.

[0065] The first laundry processing drum and the second laundry processing drum of this embodiment adopt different drying modes and have corresponding drying temperatures. The auxiliary heating device is arranged in the branch air duct of the corresponding laundry processing drum, so that the change of the inlet air temperature of different laundry processing drums is achieved. At the same time, the inlet air temperature is kept basically constant by controlling the start and stop of the auxiliary heating device, so that special clothes such as wool and silk can be dried at low temperature without affecting the drying performance of the other washing drum, thereby extending the life of different types of clothes of users.

[0066] The control method of this embodiment is also applicable to the case where there are more than two laundry processing drums. The control method is similar and will not be described in detail here.

[0067] The control method of this embodiment is described in detail below with reference to a specific example. Figure 6 After the multi-drum laundry processing device is powered on, the drying setting temperature Th is determined according to the selected mode. 设 After the first washing tub enters the drying program, it is determined whether the second washing tub is drying. If not, the first washing tub performs the normal drying program. If so, the user-selected mode is used to determine whether the first and second washing tubs have the same drying temperature standard. If so (both high-temperature drying standard or both low-temperature drying standard), the heat pump module's compressor continues to automatically adjust the frequency according to the original frequency control logic. If they have different drying temperature standards, the first washing tub is further determined to be operating at a low-temperature drying standard. The heat pump module's compressor automatically adjusts the frequency according to the compressor frequency control logic corresponding to the heating program for the low-temperature drying standard set for the first washing tub. If the second washing tub is operating at a low-temperature drying standard, the heat pump module's compressor continues to automatically adjust the frequency according to the original frequency control logic.

[0068] After determining the operating frequency of the compressor, when detecting that the first washing tub and the second washing tub enter the drying stage respectively, the actual inlet air temperature of the first washing tub and the second washing tub is monitored in real time, and the actual inlet air temperature of the first washing tub T is set to 进风 The corresponding inlet air temperature target value is Th 设1 For comparison, when T 进风 Less than (Th 设1 -5), the auxiliary heating device of the first washing drum air duct is turned on; when T 进风 Greater than or equal to Th 设1 The auxiliary heating device of the first washing drum is turned off. When it is detected that the drying stage of the first washing drum is over, the auxiliary heating device is turned off and the next stage is entered. Similarly, the actual air inlet temperature T 进风 The corresponding inlet air temperature target value is Th 设2 For comparison, when T 进风 Less than (Th 设2 -5) turn on the auxiliary heating device of the second washing tub; when T 进风 Greater than or equal to Th 设2 Then the auxiliary heating device of the second washing tub is turned off. When it is detected that the drying stage is finished, the next stage is entered.
