In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, unless they contradict each other.

[0041] The present application embodiment provides a clothes processing device, please refer to Figure 1 and Figure 2 , including a shell 1, a cylinder assembly 2, an air duct assembly 3, a first heat exchanger 5, a second heat exchanger 6 and an auxiliary heat device 8.

[0042] The clothing processing device may be a clothes dryer or a washer-dryer, and there is no limitation here.

[0043] The drum assembly 2 is arranged in the housing 1, and has a clothing processing chamber (not shown in the figure), an air inlet (not shown in the figure) and an air outlet (not shown in the figure). It can be understood that the clothing to be processed is placed in the clothing processing chamber and can be washed and cared for in the clothing processing chamber.

[0044] The air duct assembly 3 has an air duct 31 and a first fresh air port 32. The air duct 31 connects the air inlet and the air outlet. It is understandable that the hot air flow in the air duct 31 can enter the clothing processing chamber and exchange heat with the clothing in the clothing processing chamber, so as to remove moisture on the surface of the clothing during the flow process, thereby achieving drying of the clothing.

[0045] The first fresh air port 32 is in communication with the air duct 31, and is used to introduce the airflow outside the air duct 31 (hereinafter referred to as fresh air) into the air duct 31. It is understandable that the fresh air can be used as a supplementary air source for the airflow in the air duct 31, and can supplement the loss of the airflow in the air duct 31 during the circulation process, so that the air duct 31 maintains a reasonable air pressure and air volume, so as to improve the drying efficiency of the clothes processing device.

[0046] The first heat exchanger 5 is used to condense and dehumidify the airflow in the air duct 31 .

[0047] The second heat exchanger 6 is located downstream of the first heat exchanger 5 along the flow direction of the airflow, and is used to heat the airflow after condensation and dehumidification.

[0048] Exemplarily, the principle of drying clothes in the clothes processing device is as follows: in the clothes processing chamber, the dry hot air flow flows through the surface of the wet clothes, exchanges heat and moisture with the wet clothes, absorbs moisture in the clothes, and becomes a humid hot air flow, which enters the upstream of the air duct 31 through the air outlet, and flows through the first heat exchanger 5 and the second heat exchanger 6 in sequence. In the process of flowing through the first heat exchanger 5, the water vapor in the humid hot air flow is separated from the air flow due to the temperature drop and condenses into water droplets. The humid hot air flow is condensed and dehumidified by the first heat exchanger 5 to form a low-temperature dry air flow, and the low-temperature dry air flow is heated to a dry hot air flow when passing through the second heat exchanger 6. The dry hot air flow enters the clothes processing chamber from the downstream of the air duct 31 again, and the cycle is carried out in this way to achieve continuous and efficient drying of clothes.

[0049] It should be noted that the low-temperature dry airflow is relative to the humid hot airflow, and the temperature of the low-temperature dry airflow is lower than that of the humid hot airflow. The low temperature in the embodiment of the present application may be room temperature.

[0050] The auxiliary heating device 8 is used to heat the airflow after condensation and dehumidification. It is understandable that the auxiliary heating device 8 can assist in heating the airflow after condensation and dehumidification, increase the temperature of the dry hot airflow entering the clothes processing chamber, and thus improve the drying efficiency of the clothes processing device.

[0051] In the related art, the air duct introduces fresh air from the outside to supplement the airflow lost during the circulation process. However, the temperature of the fresh air from the external environment is lower than that of the airflow in the air duct, so it will reduce the temperature of the airflow entering the clothing processing chamber, thereby reducing the drying efficiency of the clothes. In the embodiment of the present application, an auxiliary heating device 8 is added. On the one hand, it can assist the second heat exchanger 6 in heating the airflow and reduce the workload of the second heat exchanger 6; on the other hand, it can increase the temperature of the airflow entering the clothing processing chamber and improve the drying efficiency of the clothing processing device.

[0052] It should be noted that the specific structure of the auxiliary heating device 8 is not limited, and it can be an electric auxiliary heating device 8.

[0053] The specific type of the first heat exchanger 5 is not limited, for example, it can be a water cooler, specifically, condensate is introduced into the water cooler, when the airflow discharged from the clothes processing chamber flows through the inside of the water cooler, the airflow and the condensate exchange heat to achieve condensation and dehumidification of the airflow. The specific type of the second heat exchanger 6 is not limited, for example, it can be resistance heating, etc.

[0054] In the embodiment of the present application, the first heat exchanger 5 is an evaporator of the heat pump system, and the second heat exchanger 6 is a condenser of the heat pump system.

[0055] It should be noted that the auxiliary heat device 8 is located downstream of the first heat exchanger 5 along the airflow direction, and the specific location is not limited.

[0056] In some embodiments, please refer to Figure 3, the auxiliary heating device 8 is located downstream of the second heat exchanger 6 along the airflow direction. It can be understood that the airflow heated by the second heat exchanger 6 needs to flow through the auxiliary heating device 8 and be heated again. In this way, the airflow is heated twice before flowing into the clothing processing chamber, which can increase the temperature of the airflow flowing into the clothing processing chamber, accelerate the heat and moisture exchange between the airflow and the clothes in the clothing processing chamber, and thus improve the drying efficiency of the clothing processing device.

[0057] In other embodiments, the first heat exchanger 5 is located upstream of the auxiliary heat device 8 along the airflow direction, and the second heat exchanger 6 is located downstream of the auxiliary heat device 8 along the airflow direction. It can be understood that the airflow after condensation and dehumidification through the first heat exchanger 5 needs to be heated by the auxiliary heat device 8 before flowing through the second heat exchanger 6 for further heating treatment. In this way, the initial temperature of the airflow when flowing through the second heat exchanger 6 can be increased, and the difference between the temperature required for heating the second heat exchanger 6 and the initial temperature can be reduced, thereby reducing the workload of the second heat exchanger 6 and improving the energy utilization rate of the clothing processing equipment.

[0058] In some embodiments, the clothing processing device further includes a fan (not shown in the figure), which is arranged on one side of the air duct assembly 3, is connected to the air duct 31, and is located downstream of the auxiliary heating device 8 along the air flow direction. It can be understood that during the operation of the fan, a negative pressure environment can be formed upstream of the fan. Since the auxiliary heating device 8 is located upstream of the fan, the airflow to the auxiliary heating device 8 is accelerated, and the airflow passing through the auxiliary heating device 8 is increased, thereby improving the heat exchange efficiency of the auxiliary heating device 8. In addition, the airflow needs to be processed by the first heat exchanger 5 before flowing through the fan, so that the water vapor content in the airflow passing through the fan is less, which can reduce the influence of water vapor on the fan, thereby improving the service life of the fan.

[0059] In some embodiments, please refer to Figure 3 , the first heat exchanger 5 and the second heat exchanger 6 are arranged in a spaced relationship along the left and right directions of the clothes processing device, and there is a spaced region 5a between the two. The back side of the spaced region 5a has an opening 5b. The first fresh air port 32 is located on the side wall of the air duct assembly 3 along the back side of the clothes processing device. The first fresh air port 32 is connected to the opening 5b, and is used to introduce the airflow outside the air duct 31 into the spaced region 5a through the opening 5b. It can be understood that the fresh air entering the air duct 31 from the first fresh air port 32 can enter the spaced region 5a between the first heat exchanger 5 and the second heat exchanger 6 from the opening 5b. In this way, the fresh air will not flow through the first heat exchanger 5, which can reduce the workload of the first heat exchanger 5 and improve the heat exchange efficiency of the first heat exchanger 5.

[0060] In the embodiment where the clothes processing device is provided with a fan, since the first fresh air outlet 32 ​​is located upstream of the fan, the fresh air is also subjected to the negative pressure and can be replenished into the air duct 31 in time to keep the air pressure in the air duct 31 within a reasonable range. In addition, due to the negative pressure, the airflow in the air duct 31 is not easy to overflow from the first fresh air outlet 32.

[0061] In some embodiments, please refer to Figure 4 , the first fresh air outlet 32 ​​faces the opening 5b. In this way, the fresh air can directly flow to the opening 5b through the first fresh air outlet 32 ​​and enter the spacing area 5a, which can reduce the air volume loss of the fresh air.

[0062] In some embodiments, please refer to Figure 3 The auxiliary heat device 8 and the first heat exchanger 5 are located on opposite sides of the second heat exchanger 6 along the left and right direction of the laundry processing device. In this way, the installation space of the air duct 31 along the left and right direction of the laundry processing device can be fully utilized, the size of the laundry processing device along the up and down direction can be reduced, and the structure is compact.

[0063] In some embodiments, please refer to Figure 3 The air duct 31 includes a filter chamber 31b and a heat exchange chamber 31a. The first heat exchanger 5 and the second heat exchanger 6 are arranged in the heat exchange chamber 31a. The filter chamber 31b is located upstream of the heat exchange chamber 31a along the air flow direction. The clothing processing device also includes a filter assembly (not shown in the figure). The filter assembly can be pulled out and arranged in the filter chamber 31b to filter the airflow in the air duct 31. It can be understood that the internal airflow will carry away impurities such as hair on the clothes while taking away the water vapor on the clothes. The internal airflow passes through the filter chamber 31b. After being filtered by the filter assembly, the impurities such as hair in the airflow will be intercepted by the filter assembly, which can reduce the impurities in the airflow flowing into the heat exchange chamber 31a, reduce the impurities attached to the first heat exchanger 5 and the second heat exchanger 6, and improve the heat exchange effect between the airflow and the first heat exchanger 5 and the second heat exchanger 6, thereby improving the drying capacity of the clothing processing device.

[0064] In some embodiments, the filter assembly includes a filter box and a handle, and the handle is arranged on the front side of the filter box. In this way, it is convenient for the user to remove or insert the filter box from the air duct assembly 3 through the handle, thereby improving the user's operation convenience.

[0065] Exemplarily, the filter box is provided with a fresh air outlet, which connects the internal space of the filter box and the external environment, and is used to guide part of the airflow flowing through the filter box to the external environment. Specifically, when fresh air needs to be introduced, the fresh air enters the air duct 31 through the first fresh air outlet 32, and is introduced into the clothing processing chamber from the downstream of the air duct 31, and enters the upstream of the air duct after flowing through the clothing processing chamber, thereby realizing circulation in the air duct 31 and the clothing processing chamber. Since the airflow of the air duct 31 introduces fresh air, the air pressure of the air duct increases. When flowing through the filter box, part of the airflow flows from the fresh air outlet of the filter box to the external environment, so that the air pressure can be balanced.

[0066] In some embodiments, the fan includes an impeller, and the rotation center of the impeller is lower than the bottom wall of the heat exchange chamber 31a. In this way, the fan is installed at a lower position, so that the space between the air duct assembly and the drum assembly can be reasonably used to install the fan, which is conducive to improving the space utilization of the clothing processing device.

[0067] In some embodiments, please refer to Figure 3 and Figure 4 The air duct includes a return air chamber 31c, and the return air chamber 31c and the heat exchange chamber 31a are arranged along the left and right directions of the clothing processing device. The auxiliary heat device 8 is arranged in the return air chamber 31c, and the bottom wall of the return air chamber 31c is lower than the bottom wall of the heat exchange chamber 31a. At least part of the bottom wall of the return air chamber 31c is formed with a guide surface, and the height of the guide surface gradually decreases from the heat exchange chamber 31a to the return air chamber 31c. It can be understood that the return air chamber 31c requires a certain space to install the auxiliary heat device 8. The downward inclination of the guide surface makes the return air chamber 31c have a larger space in the height direction, which is convenient for installing the auxiliary heat device 8, and is also conducive to controlling the overall height of the air duct assembly 3, thereby facilitating the control of the overall height of the clothing processing device.

[0068] In some embodiments, the housing 1 has a second fresh air inlet 9 along the side wall of the rear side of the laundry processing device. It should be noted that the rear side of the laundry processing device refers to the side of the laundry processing device that is away from the user after the laundry processing device is installed, that is, the rear side of the laundry processing device in the front-to-back direction. In this way, the impact of the second fresh air inlet 9 on the appearance of the laundry processing device can be reduced.

[0069] Please refer to Figure 5 The clothing processing device further includes an air guide shell 4, which connects the first fresh air outlet 32 ​​and the second fresh air outlet 9 to form a fresh air channel. It can be understood that the fresh air channel formed by the internal space of the air guide shell 4 can allow the fresh air outside the clothing processing device to be introduced into the air duct 31 from the second fresh air outlet 9, ensuring that the fresh air stably flows to the first fresh air outlet 32, and continuously provides fresh air to the air duct 31. At the same time, the air guide shell 4 can also provide protection for the first fresh air outlet 32, thereby improving the safety of the first fresh air outlet 32.

[0070] In some embodiments, please refer to Figure 5 The clothing processing device includes a damper 7 for opening or closing the fresh air passage.

[0071] It should be noted that the specific installation position of the damper 7 is not limited. For example, the damper 7 is connected to the air guide shell 4 to open or close the fresh air channel; or, the damper 7 is arranged at the first fresh air outlet 32 ​​and connected to the air duct assembly 3 to open or close the first fresh air outlet 32; or, the damper 7 is arranged at the second fresh air outlet 9 and connected to the shell 1 to open or close the first fresh air outlet 32.

[0072] In this way, the user can adjust the opening or closing of the damper 7 according to the operating conditions of the clothing processing device. For example, when the clothing processing device just starts to dry the clothes, the humidity of the air flow in the air duct 31 is relatively high. Opening the fresh air channel can introduce fresh air and mix it with the air flow in the air duct 31, which can reduce the heat load of the first heat exchanger 5 and the second heat exchanger 6. When the clothing processing device has been drying the clothes for a long time, the humidity of the air flow in the air duct 31 is relatively low, and a reasonable air flow rate is maintained in the air duct 31, and the damper 7 can be closed.

[0073] Exemplarily, one end of the air guide shell 4 surrounding the first fresh air outlet 32 ​​is detachably connected to the air duct assembly 3. In this way, it is convenient for the user to repair and replace the shell, and it is also convenient to clean or repair and replace the damper 7 after removing the shell, thereby improving the user's convenience.

[0074] It should be noted that the specific method of rotating the damper 7 is not limited. For example, in some embodiments, the rotating shaft of the damper 7 is connected to a transmission rod (not shown in the figure), the transmission rod is exposed outside the air guide housing 4, and the user can manually turn the transmission rod to manually open or close the damper 7.

[0075] In some other embodiments, the clothes processing device includes a control device (not shown in the figure) and a driving member (not shown in the figure), and the control device is used to control the driving member to rotate, and the driving member drives the damper 7 to rotate. In this way, it is convenient to realize automatic control of the damper 7 without manual intervention by the user.

[0076] In some embodiments, please refer to Figure 5 The damper 7 is provided with a sealing ring 71, which is located on one side of the damper 7 close to the first fresh air outlet 32. It can be understood that when the damper 7 is in the state of closing the fresh air passage, the sealing ring 71 can improve the sealing performance of the damper 7 to the fresh air passage, and better block the fresh air from entering the air duct 31 through the fresh air passage.

[0077] In some embodiments, the air duct assembly 3 is located above the drum assembly 2. In this way, the space of the clothes processing device along the height direction can be fully utilized to increase the internal space of the air duct assembly 3, increase the air flow that the air duct assembly 3 can accommodate, and thus improve the drying efficiency of the clothes processing device.

[0078] In some embodiments, please refer to Figure 6 to Figure 8 The housing 1 includes a top cover 11 and a box body 12, and the first fresh air inlet 32 ​​is arranged on the side wall of the rear side of the top cover 11. In this way, the influence of the first fresh air inlet 32 ​​on the box body 12 can be reduced, so that the box body 12 can be made of standard parts, which is convenient for making the box body 12.

[0079] In addition, a grille is disposed outside the first fresh air inlet 32 ​​.

[0080] The various embodiments / implementations provided in this application can be combined with each other without causing any contradiction.

[0081] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
