[0020] To achieve the above object, as shown in FIGS. 1 to 5, the present disclosure provides a clothing treatment device, which includes a first drum 100, a second drum 200, and a heat pump drying device 300. Here, the second drum 200 is located on one side of the first plane A (for example, one of the right side and the left side), the diameter of the second drum 200 is smaller than the diameter of the first drum 100, and here, the first plane A passes through the rotation center axis of the first drum 100 and is a plane parallel to the vertical direction. The heat pump drying device 300 includes a compressor 331 and a heat exchange assembly 330 connected to the compressor 331, and at least a part of the heat exchange assembly 330 is located on the other side (for example, the other of the right side and the left side) facing one side of the first plane A.

[0021] According to the above technical solution, the clothing treatment device 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 assembly 330 connected to the compressor 331. At least a part of the second drum 200 and the heat exchange assembly 330 are provided on opposite sides of the first plane A respectively. The heat exchange assembly 330 can exchange heat with the gas flowing through the heat pump drying device 300 to dry the clothes inside the first drum 100. The heat pump drying device 300 of the clothing treatment device adopts the heat exchange assembly 330 of the heat pump system to perform heat exchange, utilizes the low-temperature heat energy in the air, converts it into high-temperature heat energy by the compression of the compressor 331, sends it to the heat exchange assembly 330, and heats the gas before entering the first drum 100. Compared with the related technology, it has the characteristics of energy saving, high efficiency, and environmental protection.

[0022] In addition, by arranging at least a part of the second drum 200 and the heat exchange assembly 330 on opposite sides of the first plane A, the internal space of the clothing treatment device can be reasonably utilized.

[0023] In some embodiments, the second drum 200 and the heat exchange assembly 330 are located on the same side of the second plane B, where the second plane B passes through the rotation center axis of the first drum 100 and is a plane parallel to the left-right direction. By arranging at least a part of the second drum 200 and the heat exchange assembly 330 on the same side of the second plane B, for example, the upper side or the lower side, sufficient space can be left on the opposite side of the second plane B to arrange other components.

[0024] Here, as shown in FIG. 3, the second drum 200 is located at the upper right of the first drum 100, the heat exchange assembly 330 is located on the left side of the second drum 200, and is located above or obliquely above the first drum 100. Note that the second drum 200 may be located at the upper left of the first drum 100, the heat exchange assembly 330 may be located on the right side of the second drum 200, and is located above or obliquely above the first drum 100.

[0025] In some embodiments, the heat pump drying device 300 further includes a fan 310 and an intake pipeline 320. One end of the intake pipeline 320 is connected to the first drum 100, the other end communicates with the intake port of the fan 310, the exhaust port of the fan 310 communicates with the first drum 100, and at least a part of the heat exchange assembly 330 is provided inside the intake pipeline 320 and is used for heat exchange with the drying gas flowing through the intake pipeline 320.

[0026] The heat pump dryer 300 employs a fan 310, an intake pipe 320, a compressor 331, and a heat exchange assembly 330 connected to the compressor 331. The heat exchange assembly 330 can be installed entirely or partially inside the intake pipe 320, and it exchanges heat with the gas flowing through the intake pipe 320. After the gas has exchanged heat, it can enter the first drum 100 to dry the clothes. The heat pump dryer 300 of the garment processing equipment employs a heat exchange assembly 330 of the heat pump system to perform heat exchange, utilizing low-temperature thermal energy in the air, converting it into high-temperature thermal energy through compression by the compressor 331, and sending it to the heat exchange assembly 330 to heat the gas before it enters the first drum 100. Compared to related technologies, it has the characteristics of energy saving, high efficiency, and environmental protection.

[0027] The heat pump drying apparatus 300 may include a compressor 331, an evaporator, a condenser, and an expansion valve. The connections between each component can be found in the relevant technologies, and since this is a mature technology, a detailed explanation is omitted here. Here, the condenser is formed as the heat exchange assembly 330 described above, which heats the gas flowing through the intake pipe 320, and then the heated gas is sent to the first drum 100 by a fan 310 to dry the damp, cold clothes inside the first drum 100.

[0028] In some embodiments, the end of the intake line 320 furthest from the fan 310 is also in communication with the first drum 100, so that the moist heat gas that has exchanged heat with the clothing in the first drum 100 can be condensed, converted into a relatively dry gas, and then circulated again by the intake line 320. Here, the condensation of the moist heat gas can be carried out via a condenser provided inside the drum, and specific examples can be found in the prior art.

[0029] As shown in Figures 1 and 2, in some embodiments, the heat exchange assembly 330 includes a first heat exchanger 332 for heating the dry gas flowing through the intake pipe 320. Here, the first heat exchanger 332 may be a condenser or may be replaced by a heat exchanger with condenser-like functionality that can be dissipated by the heat pump assembly 330 and used to heat the dry gas in the intake pipe 320.

[0030] Here, the operating principle of the heat pump system is based on the inverse Carnot principle, which absorbs low-temperature thermal energy from the air with very little electrical energy, converts it into high-temperature thermal energy through compression by the compressor 331, and transmits it to the object that needs heating. With this operating method, the heat pump assembly 330 is more energy-efficient and environmentally friendly.

[0031] In some other embodiments, the heat exchange assembly 330 further includes a second heat exchanger 333 located on the side of the first heat exchanger 332 furthest from the fan 310, for condensing the dry gas entering the intake pipe 320, so that the moist heat gas that has exchanged heat with the clothing can be condensed while the gas is being heated. Here, the first heat exchanger 332 may be a condenser and the second heat exchanger 333 may be an evaporator, and the moist heat gas that has exchanged heat with the clothing enters through the intake pipe 320, first passes through the second heat exchanger 333, where it is condensed to remove moisture from the gas, and then passes through the first heat exchanger 332 to heat the dehydrated gas to satisfy the drying requirement. In this way, there is no need to provide a condensing plate inside the first drum 100 for condensing the warm gas, a synergistic effect of condensation and heating is obtained using the second heat exchanger 333 and the first heat exchanger 332, and the overall configuration of the first drum 100 is simplified.

[0032] The intake pipe 320 and the exhaust port of the fan 310 may be connected to any position on the first drum 100, as long as gas circulation can be maintained. As shown in Figure 4, in some embodiments, one end of the intake pipe 320 is connected to the upper rear of the first drum 100, and the exhaust port of the fan 310 is connected to the front of the first drum 100, and the intake pipe 320 and the exhaust port of the fan 310 can be connected to relatively far sides of the first drum 100, respectively, thereby enabling better drying of clothes inside the first drum 100. For example, by connecting the intake pipe 320 to the upper rear of the first drum 100 and the exhaust port of the fan 310 to the front of the first drum 100, the gas that enters the first drum 100 may be directed from front to back, passing through the clothes inside the first drum 100 to further enhance the drying effect.

[0033] As shown in Figure 3, in some embodiments, the fan 310 and / or the heat exchange assembly 330 are located above the first drum 100. Here, both the fan 310 and the heat exchange assembly 330 may be located above the first drum 100, or either one of them may be located above the first drum 100. For example, both the fan 310 and the heat exchange assembly 330 are located above the first drum 100, and the intake line 320 has one end connected to the rear upper part of the first drum 100 and the other end extending upward and horizontally above the first drum 100, and the heat exchange assembly 330 (first heat exchanger 332 and second heat exchanger 333) is located inside the intake line 320, and the intake line 320 communicates with the intake port of the fan 310, and the intake port of the fan 310 can be connected directly to the inlet of the front door seal of the first drum 100 or via a connecting passage, thereby allowing hot air to be sent into the first drum 100 and circulated.

[0034] The fan 310 and / or heat exchange assembly 330 may be located to the side or below the first drum 100, as long as they can satisfy the requirements for heating or condensing the gas flowing through the intake pipe 320.

[0035] The compressor 331 may be located at any position inside the housing 400 of the garment processing machine, and as shown in Figure 3, in some embodiments, the compressor 331 is located above the first drum 100 and to the side of the heat exchange assembly 330. The compressor 331 may be fixed directly to the inner wall of the housing 400, or it may be connected to the housing 400 via a reinforcing member 3311, to provide sufficient space below the first drum 100 to facilitate the placement of other components.

[0036] As shown in Figure 5, in some other embodiments, the compressor 331 may be located below the first drum 100 and connected to the housing 400 of the garment processing machine via a reinforcing member 3311. Placing the compressor 331 below the first drum 100 provides ample space above to facilitate the placement of other components.

[0037] As shown in Figures 1, 2, and 3, the garment processing machine has a double-drum structure and includes a first drum 100 and a second drum 200, the diameter of the second drum 200 being smaller than the diameter of the first drum 100. The housing 400 of the garment processing machine in this disclosure is a standard housing 400 (defined as having a width of 600 ± 50 mm, a depth of 500 to 700 mm, and a height of 850 ± 50 mm), the garment processing machine is a washing machine with a drying function, where the large drum (first drum 100) is located in the center of the housing 400, the small drum (second drum 200) is located in the upper right corner of the large drum (first drum 100), and the heat pump dryer 300 is used to dry the large drum (first drum 100).

[0038] The second drum 200 can be fixed in any suitable manner. In some embodiments, the garment processing machine further includes a housing 400 and a mounting beam 500, the mounting beam 500 located above the first drum 100 and connected to opposing sides of the housing 400, and the second drum 200 is fixed to the mounting beam 500. As shown in Figure 1, the opposing ends of the mounting beam 500 are connected to the left and right sides of the housing 400, and the second drum 200 is connected below the mounting beam 500, thereby securing the second drum 200. If the compressor 331 and intake pipe 320 are located above the first drum 100, the compressor 331 and intake pipe 320 may be fixed to the mounting beam 500 to satisfy the need for fixing both.

[0039] The fan 310 may be fixed in place by referring to the inlet position of the first drum 100. For example, if both the intake line 320 and the heat exchange assembly 330 are located above the first drum 100, the fan 310 may be fixed to the mounting beam 500. The fan 310 may also be fixed to the inner wall of the housing 400 via a reinforcing member 3311.

[0040] The garment processing apparatus of this disclosure includes a housing 400, a first drum 100 located inside the housing 400, a second drum 200, and a heat pump dryer 300, wherein the first drum 100 is located in the center of the housing 400, the second drum 200 is located in the upper right corner of the first drum 100, and the heat pump dryer 300 is used to dry the first drum 100.

The heat pump dryer 300 of the garment processing equipment employs a heat exchange assembly 330 of the heat pump system to perform heat exchange, utilizing low-temperature thermal energy in the air, converting it into high-temperature thermal energy through compression by the compressor 331, and sending it to the heat exchange assembly 330 to heat the gas before it enters the first drum 100. Compared to related technologies, it has the characteristics of energy saving, high efficiency, and environmental protection.

[0041] Furthermore, the heat exchange assembly 330 may include a first heat exchanger 332 with a heating function and a second heat exchanger 333 with a condensing function. The moist heat gas that has exchanged heat with the clothes inside the first drum 100 enters through the intake pipe 320, first passes through the second heat exchanger 333, where it condenses to remove moisture from the gas, and then passes through the first heat exchanger 332 to heat the dehydrated gas to satisfy the drying requirement. In this way, there is no need to provide a condensing plate inside the first drum 100 to condense the warm gas, a synergistic effect of condensation and heating is obtained using the second heat exchanger 333 and the first heat exchanger 332, and the overall configuration of the first drum 100 is simplified.
