[0040] 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.

[0041] The technical solution of this 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.

[0042] According to an exemplary embodiment, this embodiment proposes a clothes processing device, such as Figure 1 As shown, the laundry processing apparatus includes a washer-dryer 1 and a washtub 2. Washer-dryer 1 is preferably a drum-type washer-dryer 1. Washer-dryer 1 includes a laundry processing drum for washing or drying laundry. Washtub 2 is positioned on top of washer-dryer 1 to optimize space utilization. Washtub 2 and washer-dryer 1 are preferably designed to form an integrated structure, improving overall aesthetics and ensuring reliable assembly of the two components.

[0043] Washer-dryer 1 also includes a water inlet system, comprising a water inlet pipe 31, which can be connected to the municipal water supply. A main water inlet control valve 311 is provided on the water inlet pipe 31, allowing the user to control the flow of water between the municipal water supply and the water inlet pipe 31. A first water inlet passage 32 connects the water inlet pipe 31 to the laundry tub, and a second water inlet passage 33 connects the water inlet pipe 31 to the washtub 2. The first and second water inlet passages 32 and 33 are respectively equipped with a first water inlet control valve 321 and a second water inlet control valve 331. When the first water inlet control valve 321 is on, water in the water inlet pipe 31 enters the first water inlet passage 32 and flows into the laundry tub. When the second water inlet control valve 331 is on, water in the water inlet pipe 31 enters the second water inlet passage 33 and flows into the washtub 2. The washing tub 2 may further be provided with a water inlet device 9 at the outlet of the second water inlet passage 33. The water inlet device 9 may be, for example, a faucet, so that the user can control the water flow and the size of the water flow.

[0044] The clothing processing apparatus also includes an air supply system, which includes an air flow heating device 45, a first air supply blower 46, and an air supply duct 41. The air flow heating device 45 and the first air supply blower 46 are both disposed in the air supply duct 41. A first air supply passage 42 is connected between the air supply duct 41 and the clothing processing tub, and a second air supply passage 43 is connected between the air supply duct 41 and the washing tub 2. The first air supply passage 42 and the second air supply passage 43 are respectively provided with a first air supply control valve 421 and a second air supply control valve 431. The air supply system can, as needed, independently introduce cold or hot air into the washing tub 2 through the first air supply passage 42, independently introduce cold or hot air into the washer-dryer 1 through the second air supply passage 43, or simultaneously introduce cold or hot air into the washer-dryer 1 through the first air supply passage 42 and the second air supply passage 43.

[0045] In a preferred embodiment, Figure 1As shown, the air outlets of the first air supply duct 41 and the second air supply duct 41 are further provided with temperature sensors 8 to respectively detect the inlet air temperatures of the washer-dryer 1 and the washing tub 2. The air flow heating device 45 can adjust the heating power according to the detected inlet air temperature.

[0046] The laundry processing apparatus further comprises a control device, which is configured to determine a control strategy corresponding to an operation mode of the washing tub 2 according to a working stage of the washer-dryer 1 .

[0047] The laundry processing apparatus of this embodiment includes a washer-dryer 1 and a washing tub 2. Intelligent control of water inflow to the washer-dryer 1 and washing tub 2 is achieved by designing the water paths between a water inlet pipe 31, a first water inlet passage 32, and a second water inlet passage 33, and by on-off control of the corresponding water paths by a first water inlet control valve 321 and a second water inlet control valve 331. Simultaneously, intelligent control of hot air supply to the washer-dryer 1 and washing tub 2 is achieved by designing the air paths between an air supply pipe 41, a first air supply passage 42, and a second air supply passage 43, and by on-off control of the first air supply control valve 421 and the second air supply control valve 431. Therefore, different operating modes can be assigned to the washing tub 2 based on user needs, and intelligent control of water inflow and air supply to the washing tub 2 can be implemented based on these different operating modes.

[0048] Washtub 2 can operate in, for example, a washing mode, a rinsing mode, or an air supply mode. When the user selects the washing or rinsing mode, the water inlet conduit 31 is connected to the second water inlet passage 33. When the user selects the air supply mode, the air supply conduit 41 is connected to the second air supply passage 43. Furthermore, the water inlet system's water supply path and the air supply system's air supply path can be controlled based on the operating stage of washer-dryer 1 and the operating stage of washertub 2. This allows for intelligent control of washertub 2 while still meeting the user's diverse needs.

[0049] In some embodiments, as Figure 1As shown, the laundry processing apparatus includes a detergent dispensing device 6, which is disposed in the water inlet system and can be controlled to dispense detergent into the first water inlet passage 32 and / or the second water inlet passage 33. In addition to automatically dispensing detergent, the detergent dispensing device 6 of this embodiment can also dispense softener or disinfectant. The detergent dispensing device 6 of this embodiment includes a detergent dispensing portion, within which detergent, softener, or disinfectant is contained. The washer-dryer 1 and washtub 2 of this embodiment may each have a separate detergent dispensing portion, or the washer-dryer 1 and washtub 2 may share a detergent dispensing portion. In one example, the laundry processing apparatus includes a first detergent dispensing portion and a second detergent dispensing portion. The first detergent dispensing portion is disposed in the first water inlet passage 32 and is used to dispense detergent into the first water inlet passage 32 when the washer-dryer 1 requires detergent. The second detergent dispensing portion is disposed in the second water inlet passage 33 and is used to dispense detergent into the second water inlet passage 33 when the washtub 2 requires detergent. In another example, the washing and drying machine 1 and the washing tub 2 share a detergent dispensing part, which is arranged at the water outlet end of the water inlet pipe 31, and the first water inlet passage 32 and the second water inlet passage 33 are both connected to the detergent dispensing part. When the washing and drying machine 1 needs to dispense detergent, the detergent dispensing part dispenses detergent into the first water inlet passage 32. When the washing tub 2 needs to dispense detergent, the detergent dispensing part dispenses detergent into the second water inlet passage 33.

[0050] In some embodiments, the laundry processing apparatus includes a stirring device 7 disposed in the second water inlet passage 33 and downstream of the detergent dispensing device 6. The stirring device 7 can be controlled to activate when the detergent dispensing device 6 dispenses detergent into the second water inlet passage 33, thereby stirring the water mixed with detergent in the second water inlet passage 33 to accelerate the dissolution of the detergent in the second water inlet passage 33. In one example, the stirring device 7 includes a motor, a rotating shaft, and stirring blades. The motor is disposed outside the second water inlet passage 33. The rotating shaft passes through the wall of the second water inlet passage 33 while ensuring a seal and is connected to the motor. The stirring blades are located in the second water inlet passage 33 and disposed at the end of the rotating shaft away from the motor. The motor drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the stirring blades to rotate, thereby stirring the water mixed with detergent in the second water inlet passage 31. In other implementations, an ultrasonic stirring device can be disposed in the second water inlet passage 33 to stir the water mixed with detergent by utilizing the high-intensity vibration and shear force generated by ultrasound on the water in the second water inlet passage 33.

[0051] In some embodiments, the laundry processing apparatus includes a water heating device 5, which is disposed in the water inlet system. The water heating device 5 can be controlled to heat the water entering the second water inlet passage 33 to a temperature corresponding to the hot water setting of the wash tub 2. The washer-dryer 1 operates in two modes: a washing mode and a washing mode. In both modes, the user can select the hot water setting as needed. The water heating device 5 heats the water in the second water inlet passage 33 to the desired temperature, thereby satisfying the user's need for hot water while using the wash tub 2.

[0052] The water heating device 5 includes a water heating unit that heats water. The washer-dryer 1 and washtub 2 of this embodiment may each have a separate water heating unit, or they may share a water heating unit. In one example, the laundry processing apparatus includes a first water heating unit and a second water heating unit. The first water heating unit is located in the first water inlet passage 32 and is used to heat water in the first water inlet passage 32 when the washer-dryer 1 requires hot water. The second water heating unit is located in the second water inlet passage 33 or at the bottom of the outer drum of the washer-dryer 1 and is used to heat wash water when the washer-dryer 1 requires heating. In another example, washer-dryer 1 and washtub 2 share a water heating unit, which is located in water inlet pipe 31. If only washer-dryer 1 requires hot water, the water heating unit heats the water in water inlet pipe 31 to the required hot water temperature for washer-dryer 1 and passes the hot water in water inlet pipe 31 into a first water inlet passage 32. If only washtub 2 requires hot water, the water heating unit heats the water in water inlet pipe 31 to the required hot water temperature for washtub 2 and passes the hot water in water inlet pipe 31 into a second water inlet passage 33. If both washer-dryer 1 and washtub 2 require hot water, the water heating unit prioritizes heating the water in water inlet pipe 31 to the higher required water temperature, based on the required hot water temperatures for washer-dryer 1 and washtub 2. If the water temperature in the water inlet pipe is higher than that required by washer-dryer 1, cold water is added to the first water inlet passage 32 via a water supply line connected to the first water inlet passage 32 to adjust the water temperature to the required temperature for washer-dryer 1. When the water temperature in the water inlet pipe 31 is higher than the water temperature required by the washing tub 2 , the water temperature is adjusted to the temperature required by the washing tub 2 through a mixing valve provided at the water outlet end of the second water inlet passage 33 .

[0053] In some embodiments, the air supply system further includes a third air supply passage 44, which connects the second air supply passage 43 with the outside environment. A second air supply blower 47 is provided in the third air supply passage 44, which is used to transport air from the outside environment into the third air supply passage 44. A third air supply control valve 441 is also provided in the third air supply passage 44. Air within the air supply duct 41 is activated by the first air supply blower 46 to generate an airflow. If only washer-dryer 1 requires hot air, hot air flows through the first air supply passage 42 and into washer-dryer 1 when the air supply duct 41 is connected to the first air supply passage 42. If only washing tub 2 requires hot air, hot air flows through the second air supply passage 43 and into washer-dryer 1 when the air supply duct 41 is connected to the second air supply passage 43. If both washing tub 2 and washing tub 2 require hot air, the hot air generated in the air supply duct 41 flows into both washing tub 2 and washing tub 1.

[0054] In a preferred embodiment, when the washer-dryer 1 is in the drying state and the washer-dryer 1 has a demand for hot air supply and the washing tub 2 has a demand for hot air supply, the air flow heating device 45 is controlled to preferentially heat the air in the air supply duct 41 to the hot air temperature required by the washer-dryer 1, and then obtain the air outlet temperature of the second air supply passage 43. When the air outlet temperature of the second air supply passage 43 is higher than the hot air temperature required by the washing tub 2, the air flow passage between the third air supply passage 44 and the second air supply passage 43 of the clothing processing equipment is opened. Under the action of the second air supply fan 47, the external air enters the second air supply passage 43 to cool the hot air flow of the second air supply passage 43. The hot air temperature in the second air supply passage 43 can be adjusted by controlling the opening of the third air supply control valve 441 and the speed of the second air supply fan 47, so that the hot air temperature in the second air supply passage 43 reaches the hot air temperature required by the washing tub 2. When the air outlet temperature of the second air supply passage 43 is lower than the hot air temperature required by the washing tub 2, the heating temperature of the air flow heating device 45 is increased, and the maximum drying temperature protection value of the washing and drying machine 1 is increased. The increase in the maximum drying temperature protection value is determined according to the increase in the heating temperature of the air flow heating device 45. For example, when the heating temperature of the air flow heating device 45 increases by T°C, the heat loss in the first air supply passage 42 is T1°C, and the maximum drying temperature protection value is increased by T-T1°C. If the heat loss is ignored, the increase in the drying temperature protection value is the same as the increase in the heating temperature of the heating device.

[0055] According to an exemplary embodiment, this embodiment provides a control method for a clothes processing device, and the control method is used to control the clothes processing device of the above embodiment. Figure 2 is one of the flow charts of a clothes treating apparatus according to an exemplary embodiment, referring to Figure 2 , the control method comprises the following steps:

[0056] S21. When receiving a working instruction of the washing tub 2, obtaining an operating mode of the washing tub 2;

[0057] S22 : Determine the working stage of the washer-dryer 1 , and determine a control strategy corresponding to the operation mode based on the working stage of the washer-dryer 1 .

[0058] The control method of this embodiment is executed by a control device, which can simultaneously control the operation of the washing tub 2 and the washer-dryer 1. The user can send work instructions through the control panel of the washing tub 2, or send control instructions through a mobile terminal bound to the washing tub 2. The work instructions include the operating mode of the washer-dryer 1 and the operating parameters based on the operating mode. For example, when the user issues a washing mode instruction to the washing tub 2, the washing mode instruction includes the washing water level and washing temperature in the washing mode. When the user issues a washing mode instruction to the washing tub 2, the washing mode instruction includes the washing water temperature. When the user issues a blowing mode instruction to the washing tub 2, the blowing mode instruction includes the blowing temperature and blowing wind speed.

[0059] When receiving an operating instruction for washtub 2, the operating mode of washtub 2 is first determined, and then the components and pipelines that need to be activated based on the operating mode are determined. For example, in washing and rinsing modes, the water inlet pipe 31 needs to be connected to the second water inlet passage 33, and if the user requires hot water, the water heating device 5 needs to be activated. In blowing mode, the air supply pipe 41 and the second air supply passage 43 need to be connected, and if the user requires air supply, the air flow heating device 45 needs to be activated. The operating stage of washer-dryer 1 is then determined, and the control strategy corresponding to the operating mode is determined based on the operating stage of washer-dryer 1.

[0060] Figure 3 This is a second flow chart of a clothes processing apparatus according to an exemplary embodiment, referring to Figure 3 The control method comprises the following steps: determining the working stage of the washer-dryer 1, and determining a control strategy corresponding to the operating mode based on the working stage of the washer-dryer 1, comprising the following steps:

[0061] S31, determining the water inlet state and hot air supply state of the washer-dryer 1 according to the working stage of the washer-dryer 1;

[0062] S32, determining the water inlet demand and air supply demand of the washing tub 2 according to the operation mode of the washing tub 2;

[0063] S33. Determine the on / off status of the first water inlet control valve 321 and the second water inlet control valve 331 according to the water inlet status of the washing and drying machine 1 and the water inlet demand of the washing tub 2, and determine the on / off status of the first air supply control valve 421 and the second air supply control valve 431 according to the hot air supply status of the washing and drying machine 1 and the air supply demand of the washing tub 2.

[0064] In this embodiment, the first water inlet passage 32 and the first air supply passage 42 have different conduction states during different operating stages of the washer-dryer 1. For example, when the washer-dryer 1 is in the washing and water supply phase, the water inlet conduit 31 is connected to the first water inlet conduit 32 to allow water to enter the laundry tub. When the washer-dryer 1 is in the drying phase, the air supply conduit 41 is connected to the first air supply conduit 42 to allow hot air to enter the laundry tub. Furthermore, different operating modes of the washtub 2 correspond to different water inlet and air supply requirements. For example, the washing and washing modes require hot water inlet, while the air supply mode requires hot air supply. Therefore, the water inlet and air supply systems must be regulated by combining the water inlet and air supply states during different operating stages of the washer-dryer 1, as well as the water inlet and air supply requirements of the washtub 2 during different operating modes, to achieve the different functions of the washtub 2 without affecting the normal operation of the washer-dryer 1.

[0065] In a specific example, when washer-dryer 1 is in the washing phase, the user selects the washing mode for washing tub 2. The second water inlet control valve 331 connects the water inlet pipe 31 to the second water inlet passage 33, and the water heating device 5 heats the water to the user-set temperature before supplying it to the user through the water inlet device 9. The user selects the air supply mode for washing tub 2. The first air supply blower 46 is turned on, the second air supply control valve 431 connects the air supply pipe 41 to the second air supply passage 43, and the air flow heating device 45 is turned on to deliver hot air into the laundry tub.

[0066] When the washer-dryer 1 is in the drying stage, the user selects the operating mode of the washtub 2 as the washing or washing mode. The second water inlet valve connects the water inlet pipe 31 to the second water inlet passage 33, and the water heating device 5 heats the water to the user's set temperature before supplying it to the user through the water inlet device 9. The user selects the operating mode of the washtub 2 as the blowing mode. At this time, the first air supply blower 46 and the air flow heating device 45 are turned on. The second air supply control valve 431 connects the air supply pipe 41 to the second air supply passage 43, and the air flow heating device 45 is turned on to deliver hot air into the clothing processing tub.

[0067] In some embodiments, the control method includes: determining a water inlet level and a hot water level when the washtub 2 requires water; controlling water inflow into the washtub 2 to the water level corresponding to the water inlet level; and controlling the water heating device 5 of the laundry processing apparatus to heat the water in the second water inlet passage 33 to the hot water temperature corresponding to the hot water level. For example, in the wash mode, the user can select modes such as hand washing, face washing, and hair washing. The specific modes are merely examples. After the user selects a mode, the interface jumps. The operation panel of the washtub 2 includes a water temperature button, which allows water temperature selections such as cold water, 20°C, 30°C, and 40°C. The adjustment range can be set in the settings interface. The default water temperature adjustment range is 10°C, and the last user setting can be memorized. After receiving the user's selection of the hot water level, the second water inlet passage 33, heated by the water heating device 5, delivers hot water at the temperature corresponding to the water inlet level to the washtub 2. In the laundry mode, users can choose modes such as shirts, underwear, baby clothes, and custom. After the user selects a mode, the interface jumps. The operation interface of the washing basin 2 also has a water temperature button and a water level button. The water temperature selection is the same as the washing mode, and the water level can be selected from three different water levels: high, medium, and low.

[0068] In some embodiments, the control method includes: determining the desired hot air level for washing tub 2 when washing tub 2 requires air supply; detecting the outlet air temperature of second air supply passage 43; and, if the outlet air temperature is greater than a set temperature corresponding to the hot air level, controlling the connection between third air supply passage 44 and second air supply passage 43 of the clothing processing device, thereby controlling the flow of ambient air into second air supply passage 43 via third air supply passage 44. For example, after the user selects the blow-drying mode, the interface jumps to the operation panel of washing tub 2, which includes buttons for outlet air temperature and air volume. The outlet air temperature can be selected from cold air, 30°C, 40°C, etc., with the same adjustment amplitude as the water temperature, or it can be memorized according to the last parameter setting.
