The above definitions are only used to explain and illustrate the present disclosure and should not be understood as limitations on the present disclosure.

[0030] In order to achieve the above purpose, Figures 1 to 4As shown, the present disclosure provides a laundry processing device, which includes a first drum 100, a second drum 200, and a heat pump drying device 300. The second drum 200 has a diameter smaller than that of the first drum 100 and is located on one side of a first plane A, wherein the first plane A is a plane passing through the rotation center axis of the first drum 100 and parallel to the up-down direction; the heat pump drying device 300 includes a compressor 331 and a heat exchange module 330 connected to the compressor 331, at least a portion of the heat exchange module 330 is located on the other side opposite to the first plane A, and the heat exchange module 330 is located below or to the side below the first drum 100.

[0031] The laundry treatment apparatus of the present disclosure, based on the above technical solution, includes a first drum 100, a second drum 200, and a heat pump drying device 300. The heat pump drying device 300 includes a compressor 331 and a heat exchange module 330 connected to the compressor 331. The heat exchange module 330 is configured to exchange heat with air flowing through the heat pump drying device, thereby drying the laundry within the first drum 100. The heat pump drying device 300 of the laundry treatment apparatus utilizes the heat exchange module 330 of a heat pump system for heat exchange. For example, the heat exchange module 330 utilizes low-temperature heat energy in the air, which is converted to high-temperature heat energy through compression by the compressor 331 and then transferred to the heat exchange module 330 to heat the air being treated. Compared to related technologies, the heat exchange module 330 is energy-efficient, highly efficient, and environmentally friendly. Furthermore, the heat exchange module 330 is located below or to the side of the first drum 100, saving space above the first drum 100 and facilitating the placement of other components, such as a detergent box.

[0032] It should be noted that the second drum 200 and at least part of the heat exchange module 330 are respectively arranged on opposite sides of the first plane A, so that the heat exchange module 330 can balance the weight of the second drum 200 in the left and right directions.

[0033] In some embodiments, the second drum 200 is located below the side of the first drum 100 and is fixedly connected to the housing 400 of the laundry processing device through a fixing bracket 500. Figure 2As shown, the laundry processing apparatus may include a housing 400, a first drum 100 located within the housing 400, a second drum 200, and a heat pump drying device 300 for drying clothes in the first drum 100. The second drum 200 may be located below or to the lower side of the first drum 100, and the diameter of the second drum 200 may be smaller than that of the first drum 100. The first drum 100 and the second drum 200 may be arranged in any suitable manner, such as an up-and-down arrangement or a staggered arrangement. In some embodiments, the second drum 200 is located to the lower side (e.g., the lower right side) of the first drum 100 and is fixedly connected to the housing 400 of the laundry processing apparatus via a fixing bracket 500. The term "lower side" here refers to the second drum 200 being located below a second plane B, where the second plane B is a plane passing through the rotational axis of the first drum 100 and parallel to the left-right direction.

[0034] It should be noted that, in order to improve the stability of the second drum 200, one end of the fixing bracket 500 can be connected to the inner wall of the box body 400, and the other end can be connected to the first drum 100. By arranging the second drum 200 and the heat exchange module 330 below the first drum 100, the lower space is fully utilized, while also leaving space above the first drum 100 for other components.

[0035] Of course, if space permits, the second drum 200 may also be located laterally below the first drum 100 , that is, the upper surface of the second drum 200 is located below the lower surface of the first drum 100 in the up and down direction.

[0036] In some embodiments, the heat pump drying device 300 also includes a fan 310 and an air inlet duct 320; one end of the air inlet duct 320 is connected to the first drum 100, and the other end is connected to the air inlet of the fan 310, and the air outlet of the fan 310 is connected to the first drum 100; the heat pump system includes a compressor 331 and a heat exchange module 330 connected to the compressor 331, the heat exchange module 330 is located below the first drum 100, and at least part of the heat exchange module 330 is arranged inside the air inlet duct 320, for heat exchange with the drying gas flowing through the air inlet duct 320.

[0037] The laundry processing apparatus disclosed herein includes a first drum 100, a second drum 200, and a heat pump drying device 300. The heat pump drying device 300 utilizes a fan 310, an air inlet duct 320, a compressor 331, and a heat exchange module 330 connected to the compressor 331. The heat exchange module 330 can be located within the air inlet duct 320 to perform heat exchange with air flowing through the air inlet duct 320 before entering the first drum 100 to dry the laundry. The heat pump drying device 300 utilizes the heat exchange module 330 of a heat pump system for heat exchange. The heat exchange module 330 utilizes low-temperature heat energy in the air, which is converted to high-temperature heat energy through compression by the compressor 331 and then transferred to the heat exchange module 330 to heat the air entering the first drum 100. Compared to related art, the heat pump drying device 300 is energy-efficient, highly efficient, and environmentally friendly. Furthermore, the heat exchange module 330 can be located below or to the side of the first drum 100, saving space above the first drum 100 and facilitating the placement of other components, such as a detergent box.

[0038] It should be noted that the heat pump drying device 300 includes a compressor 331, an evaporator, a condenser, an expansion valve, and other components necessary for the operation of the heat pump system. The connection relationship between these components can be referenced in related art. Since heat pump systems are mature technology in the air conditioning field, the specific structure can be referenced to the structure of air conditioning systems and will not be described in detail here. The condenser forms the aforementioned heat exchange module 330, which is used to heat the air flowing through the air inlet pipe 320. The heated air is then delivered to the first drum 100 by the fan 310 to dry the wet and cold clothes in the first drum 100.

[0039] In some embodiments, because the end of the air inlet duct 320 remote from the fan 310 is also connected to the first drum 100, the hot and humid air in the first drum 100, after exchanging heat with the clothes, can be condensed and converted into relatively dry air before being recirculated through the air inlet duct 320. The condensation of the hot and humid air can be performed using a condensation tray disposed within the drum. For details, reference can be made to existing technologies.

[0040] The air inlet pipe 320 and the air outlet of the fan 310 can be connected to any position of the first drum 100, as long as they can meet the circulation of the gas. Figure 3 As shown, in some embodiments, one end of the air inlet duct 320 is connected to the rear end of the first drum 100 , and the air outlet of the fan 310 is connected to the front end of the first drum 100 .

[0041] The air inlet duct 320 and the air outlet of the fan 310 can be connected to the rear end and the front end of the first drum 100, respectively. That is, the air inlet and air outlet are located at the front and rear ends of the first drum 100, respectively, to facilitate better drying of the clothes inside the first drum 100. For example, the air inlet duct 320 can be connected to the middle of the rear end of the first drum 100, and the air outlet of the fan 310 can be connected to the door seal position at the front end of the first drum 100, so that the air entering the first drum 100 can flow from front to back, thereby passing through the clothes inside the first drum 100 and achieving a better drying effect.

[0042] like Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments, the fan 310 is located below or to the side of the first drum 100. The fan 310 can be located below or to the side of the first drum 100. For example, the fan 310 and the heat exchange module 330 are both located below the first drum 100. One end of the air inlet duct 320 is connected to the rear end of the first drum 100, and the other end extends downward and horizontally below the first drum 100. The heat exchange module 330 (first heat exchanger 332 and second heat exchanger 333) is located within the air inlet duct 320 and can be located directly below the first drum 100. The air inlet duct 320 is connected to the air inlet of the fan 310 located below the first drum 100. The air inlet of the fan 310 can be connected directly or through a connecting duct 311 to the inlet on the door seal at the front of the first drum 100, thereby delivering hot air into the first drum 100 for circulation.

[0043] The laundry processing apparatus also includes a housing 400, within which the first drum 100, the second drum 200, and the heat pump drying device 300 are disposed. The compressor 331 can be positioned anywhere within the housing 400 and communicates with the first heat exchanger 332, the expansion valve (not shown), and the second heat exchanger 333 via heat exchange piping. In some embodiments, the compressor 331 can be located below or to the side of the first drum 100, and to the side of the heat exchange module 330. The compressor 331 can be directly fixed to the inner wall of the housing 400, or connected to the bottom of the housing 400 via a reinforcement 3311, providing ample space above the first drum 100 for arranging other components.

[0044] like Figure 4As shown, in other embodiments, the laundry processing apparatus further includes a housing 400; the compressor 331 may be located above the first drum 100 and connected to the housing 400 via a reinforcement 3311. Placing the compressor 331 above or to the side of the first drum 100 provides sufficient space below, making it convenient to arrange other components in the lower space of the laundry processing apparatus.

[0045] Optionally, the heat exchange module 330 includes a first heat exchanger 332, which is used to heat the drying gas flowing through the air inlet pipe 320. The first heat exchanger 332 can be a condenser or a heat exchanger with similar condenser functions. It can release heat in the heat pump drying device 300 and heat the drying gas in the air inlet pipe 320.

[0046] The heat pump system operates based on the reverse Carnot principle, absorbing low-temperature heat from the air using minimal electrical energy. This heat is then compressed by compressor 331 into high-temperature heat, which is then transferred to the object requiring heating. This operating method makes heat pump drying device 300 more energy efficient and environmentally friendly.

[0047] To simultaneously heat the air and condense the hot and humid air after exchanging heat with the clothes, in some embodiments, the heat exchange module 330 further includes a second heat exchanger 333. The second heat exchanger 333 is located on the side of the first heat exchanger 332 away from the fan 310 and is used to condense the drying air entering the air inlet duct 320. The first heat exchanger 332 is a condenser, and the second heat exchanger 333 is an evaporator. After entering the air inlet duct 320, the hot and humid air after exchanging heat with the clothes first passes through the second heat exchanger 333, where it is condensed to remove moisture. The dehydrated air then passes through the first heat exchanger 332 to heat the dehydrated air to meet drying requirements. This configuration eliminates the need for a condensation pan within the first drum 100 to condense the warm air. This allows the second heat exchanger 333 and the first heat exchanger 332 to achieve both condensation and heating, simplifying the overall structure of the first drum 100.

[0048] like Figure 1 and Figure 2As shown, the laundry processing device has a dual-drum structure, including a first drum 100 and a second drum 200, wherein the diameter of the second drum 200 is smaller than that of the first drum 100. The cabinet 400 of the laundry processing device disclosed herein is a standard cabinet 400 (a standard cabinet 400 is defined as 600±50mm wide, 500-700mm deep, and 850±50mm high). The laundry processing device is a washing machine with a drying function, wherein the large drum (first drum 100) is located in the middle of the cabinet 400, and the small drum (second drum 200) is located at the lower right corner of the large drum (first drum 100). The heat pump drying device 300 is used to dry the large drum (first drum 100). Due to the above arrangement, the first drum 100, the second drum 200, and the heat pump drying device 300 can be reasonably arranged inside the laundry processing device of the standard cabinet, meeting the needs of smaller usage scenarios.

[0049] The central axis of the second drum 200 can be arranged parallel to the central axis of the first drum 100. In some embodiments, the central axis of the second drum 200 can also be arranged crosswise to the central axis of the first drum 100. Optionally, the second drum 200 is arranged upwardly and tilted from the inside toward the opening. Since the second drum 200 is arranged near the bottom, it is tilted upwardly from the back to the front, making it easier for users to take clothes in and out, thereby reducing the inconvenience caused by the low opening of the second drum 200.

[0050] It should be noted that the fixing convenience of the second roller 200 can refer to the fixing convenience of the first roller 100. For example, a support plate can be arranged on the bottom plate of the box body 400, and the second roller 200 can be fixed by connecting the buffering and shock-absorbing device to the support plate and the second roller 200. Of course, those skilled in the art can fix the second roller 200 by other fixing methods, but since it is not the technical problem to be solved by this application, it will not be described here in detail.

[0051] The laundry processing apparatus disclosed herein includes a first drum 100, a second drum 200, and a heat pump drying device 300. The heat pump drying device 300 utilizes a fan 310, an air inlet duct 320, a compressor 331, and a heat exchange module 330. The heat exchange module 330 may be at least partially located within the air inlet duct 320, exchanging heat with air flowing through the air inlet duct 320 before entering the first drum 100 to dry the laundry. The heat pump drying device 300 utilizes the heat exchange module 330 of a heat pump system for heat exchange. The heat exchange module 330 utilizes low-temperature heat energy in the air, which is converted to high-temperature heat energy through compression by the compressor 331 and then transferred to the heat exchange module 330 to heat the air entering the first drum 100. Compared to related art, the heat pump drying device 300 exhibits energy-saving, high-efficiency, and environmentally friendly features. Furthermore, the heat exchange module 330 is located below or to the side of the first drum 100, saving space above the first drum 100 and facilitating the placement of other components, such as a detergent container. Meanwhile, the second drum 200 and at least part of the heat exchange module 330 are respectively arranged on opposite sides of the first plane A, so that the heat exchange module 330 can balance the weight of the second drum 200 in the left-right direction.

[0052] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.

[0053] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0054] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
