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

[0034] In order to achieve the above purpose, Figures 1 to 5 As shown, the present disclosure provides a laundry processing apparatus, which includes a first drum 100, a second drum 200, and a heat pump drying device 300. The second drum 200 is located on one side of a first plane A (e.g., one of the right and left sides), and the diameter of the second drum 200 is smaller than the diameter of the first drum 100. The first plane A is a plane passing through the rotational axis of the first drum 100 and parallel to the vertical direction. The heat pump drying device 300 includes a compressor 331 and a heat exchange module 330 connected to the compressor 331, with at least a portion of the heat exchange module 330 located on the other side opposite the first plane A (e.g., the other of the right and left sides).

[0035] Through the above-described technical solution, the laundry processing apparatus of the present disclosure 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 second drum 200 and at least a portion of the heat exchange module 330 are respectively arranged on opposite sides of a first plane A. The heat exchange module 330 can be used to exchange heat with air flowing through the heat pump drying device 300, thereby drying the laundry within the first drum 100. The heat pump drying device 300 of the laundry processing apparatus utilizes the heat exchange module 330 of a heat pump system for heat exchange. The heat energy in the air is converted into high-temperature heat energy through compression by the compressor 331, and then transmitted to the heat exchange module 330 to heat the air entering the first drum 100. Compared with related technologies, the heat pump drying device 300 of the laundry processing apparatus is energy-saving, highly efficient, and environmentally friendly.

[0036] It should be noted that, by arranging the second drum 200 and at least part of the heat exchange module 330 on opposite sides of the first plane A, the internal space of the clothes processing apparatus can be reasonably utilized.

[0037] In some embodiments, the second drum 200 and the heat exchange module 330 are located on the same side of a second plane B, which is the rotational axis of the first drum 100 and is parallel to the left-right direction. By arranging the second drum 200 and at least part of the heat exchange module 330 on the same side of the second plane B, such as the upper or lower side, sufficient space is left on the other side of the second plane B for other components.

[0038] Among them, such as Figure 3As shown, the second drum 200 is located to the upper right of the first drum 100, and the heat exchange module 330 is located on the left side of the second drum 200, and is located above or to the upper side of the first drum 100. It should be noted that the second drum 200 can also be located to the upper left of the first drum 100, and the heat exchange module 330 can be located to the right side of the second drum 200, and is located above or to the upper side of the first drum 100.

[0039] 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; 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.

[0040] 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 entirely or partially located within the air inlet duct 320, performing heat exchange with the air flowing through the air inlet duct 320. After heat exchange, the air then enters the first drum 100 to dry the clothes. The heat pump drying device 300 of this clothing processing equipment utilizes the heat exchange module 330 of a heat pump system for heat exchange. It utilizes low-temperature heat energy in the air, converting it into high-temperature heat energy through compression by the compressor 331. This heat energy is then transferred to the heat exchange module 330 to heat the air entering the first drum 100. Compared to related technologies, this device is energy-efficient, highly efficient, and environmentally friendly.

[0041] It should be noted that the heat pump drying device 300 includes a compressor 331, an evaporator, a condenser, and an expansion valve. The connections between these components can be found in related art. Since this is mature technology, it 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.

[0042] 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.

[0043] like Figure 1 and Figure 2As shown, in some embodiments, 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 functions to a condenser, which can release heat in the heat pump module 330 to heat the drying gas in the air inlet pipe 320.

[0044] The heat pump system operates based on the reverse Carnot principle. Using minimal electrical energy, it absorbs low-temperature heat from the air, compresses it into high-temperature heat through compressor 331, and then transfers it to the object to be heated. This operating method makes heat pump module 330 more energy efficient and environmentally friendly.

[0045] 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.

[0046] 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 the air circulation is sufficient. Figure 4 As shown, in some embodiments, one end of the air inlet duct 320 is connected to the upper rear portion of the first drum 100, and the air outlet of the fan 310 is connected to the front portion of the first drum 100. The air inlet duct 320 and the air outlet of the fan 310 can be connected to two relatively distant sides 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 upper rear portion of the first drum 100, and the air outlet of the fan 310 can be connected to the front portion 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.

[0047] like Figure 3As shown, in some embodiments, the fan 310 and / or the heat exchange module 330 are located above the first drum 100. The fan 310 and the heat exchange module 330 can both be located above the first drum 100, or either one can be located above the first drum 100. For example, the fan 310 and the heat exchange module 330 are both located above the first drum 100. One end of the air inlet duct 320 is connected to the upper rear portion of the first drum 100, and the other end extends upward and then horizontally above the first drum 100. The heat exchange module 330 (the first heat exchanger 332 and the second heat exchanger 333) is located within the air inlet duct 320. The air inlet duct 320 is connected to the air inlet of the fan 310. The air inlet of the fan 310 can be connected directly or through a connecting channel to the inlet on the door seal at the front of the first drum 100, thereby delivering hot air into the interior of the first drum 100 for circulation.

[0048] It should be noted that the fan 310 and / or the heat exchange module 330 can also be arranged on the side or below the first drum 100, so as to heat or condense the gas flowing through the air inlet pipe 320.

[0049] The compressor 331 can be arranged at any position inside the cabinet 400 of the laundry processing apparatus, such as Figure 3 As shown, in some embodiments, the compressor 331 is located above 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 housing 400 via a reinforcement 3311, providing sufficient space below the first drum 100 for arranging other components.

[0050] like Figure 5 As shown, in other embodiments, the compressor 331 can also be located below the first drum 100 and connected to the cabinet 400 of the laundry processing device through a reinforcement 3311. The compressor 331 is arranged below the first drum 100, thereby providing sufficient space for the upper part to facilitate the arrangement of other components.

[0051] like Figure 1 、 Figure 2 and Figure 3As shown, the laundry processing device has a dual-drum structure, including a first drum 100 and a second drum 200, with the diameter of the second drum 200 being 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 in the upper 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).

[0052] The second drum 200 can be fixed in any suitable manner. In some embodiments, the laundry processing apparatus further includes a housing 400 and a mounting beam 500. The mounting beam 500 is located above the first drum 100 and connected to opposite sides of the housing 400. The second drum 200 is fixedly connected to the mounting beam 500. Figure 1 As shown, the opposite ends of the mounting beam 500 are respectively connected to the left and right sides of the box body 400, and the second drum 200 is connected below the mounting beam 500, thereby fixing the second drum 200. It should be noted that when the compressor 331 and the air inlet duct 320 are arranged above the first drum 100, the compressor 331 and the air inlet duct 320 can also be fixedly connected to the mounting beam 500 to ensure the fixation of both.

[0053] The fan 310 can also be fixed in a position based on the inlet position of the first drum 100. For example, when the air inlet duct 320 and the heat exchange module 330 are both arranged above the first drum 100, the fan 310 can also be fixedly connected to the mounting beam 500. It should be noted that the fan 310 can also be fixedly connected to the inner wall of the box body 400 via a reinforcement member 3311.

[0054] The clothes processing device of the present disclosure includes a housing 400, and a first drum 100, a second drum 200, and a heat pump drying device 300 located inside the housing 400. The first drum 100 is located in the middle of the housing 400, and the second drum 200 is located at the upper right corner of the first drum 100. The heat pump drying device 300 is used to dry the first drum 100. The heat pump drying device 300 includes a fan 310, an air inlet pipe 320, a compressor 331, and a heat exchange module 330 connected to the compressor 331. The heat exchange module 330 is disposed inside the air inlet pipe 320 and is used to perform heat exchange with the air flowing through the air inlet pipe 320. After heat exchange, the air enters the first drum 100 to dry the clothes. The heat pump drying device 300 of the clothing processing equipment adopts the heat exchange module 330 of the heat pump system for heat exchange, utilizing the low-temperature heat energy in the air, converting it into high-temperature heat energy through compression by the compressor 331, and transmitting it to the heat exchange module 330 to heat the gas to be entered into the first drum 100. Compared with related technologies, it has the characteristics of energy saving, high efficiency and environmental protection.

[0055] Furthermore, the heat exchange module 330 may include a first heat exchanger 332 with a heating function and a second heat exchanger 333 with a condensing function. This allows the hot and humid air from the first drum 100, after exchanging heat with the laundry, to enter the air inlet duct 320 and first pass through the second heat exchanger 333, where it is condensed to remove moisture from the air. The air is then heated by the first heat exchanger 332 to meet drying requirements. This arrangement eliminates the need for a condensation pan within the first drum 100 to condense the warm air. This facilitates the dual condensation and heating functions of the second heat exchanger 333 and the first heat exchanger 332, simplifying the overall structure of the first drum 100.

[0056] 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.

[0057] 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.

[0058] 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.
