[0024] like Figures 1-5 As shown, the multi-zone washing machine of this embodiment includes a first drum 1, a second drum 2, and a washing zone 3. The first drum 1 and the second drum 2 are arranged vertically at intervals. The washing zone 3 is located between the first drum 1 and the second drum 2. It also includes a drying system 4. The front-to-back width of the washing zone 3 is smaller than the front-to-back width of the first drum 1 and the second drum 2, thus forming an installation space 100 on its rear side. The heat pump module 41 of the drying system 4 is located in the installation space 100 and is connected to the air outlets of the first drum 1, the second drum 2, and the washing zone 3, respectively. The fan 42 of the drying system 4 is located on the side of the heat pump module 41 and is connected to the air outlet of the heat pump module 41 and the air inlet of the first drum 1, the second drum 2, and the washing zone 3, respectively.

[0025] Among them, the heat pump module 41 is mainly used to separate water in the input medium and heat the air before input. Its specific structure and operating principle are existing mature technologies, and will not be described in detail here.

[0026] With the above structure, the first drum 1, the second drum 2, and the washing zone 3 share a single drying system 4, which simplifies the overall structure and reduces costs. The installation space 100 between the first drum 1 and the second drum 2 is divided into two parts: the front part is used to install the washing zone 3 structure, and the rear part is used to install the drying system 4. This makes full use of the installation space 100 of the washing machine, thereby facilitating reasonable control of the overall height of the washing machine and making it convenient for users to operate.

[0027] The air outlet ducts of the first drum 1 and the second drum 2 are arranged on the first side of the washing machine, and the air inlet ducts are arranged on the second side of the washing machine. The heat pump module 41 is arranged in the installation space 100 near the air outlet duct on the first side of the washing machine, and the fan 42 is arranged in the installation space 100 near the air inlet duct on the second side of the washing machine. This structure allows for a compact arrangement of all components, making more rational use of the installation space 100 and improving space utilization.

[0028] A first air outlet pipe 11 is provided on the top wall at the rear of the first roller 1, and a second air outlet pipe 21 is provided on the top wall at the rear of the second roller 2. The first air outlet pipe 11 and the second air outlet pipe 21 are connected to each other and then connected to the inlet of the heat pump module 41. A control valve 200 is provided at the connection point between the first air outlet pipe 11 and the second air outlet pipe 21 to control whether the two are connected. This structure makes it easy to control whether the first roller 1 and the second roller 2 emit air as needed.

[0029] A third air outlet duct 31 is installed on the top wall at the rear of the washing zone 3. This third air outlet duct 31 connects to the inlet of the heat pump module after converging at the junction of the first air outlet duct 11 and the second air outlet duct 21. This structure facilitates the guidance of the air outlet from the washing zone 3 to the heat pump module for condensate removal and heating.

[0030] A first air inlet pipe 12 is provided on the top wall of the front part of the first drum 1, and a second air inlet pipe 22 is provided on the top wall of the front part of the second drum 2. The air outlet of the fan 42 is divided into two paths and connected to the first air inlet pipe 12 and the second air inlet pipe 22 respectively. The first air inlet pipe 12 is provided with a first air valve 01 that can control whether it is connected or not, and the second air inlet pipe 22 is provided with a second air valve 02 that can control whether it is connected or not. With the above structure, it is convenient to control whether the first drum 1 and the second drum 2 return air according to the washing needs.

[0031] A third air inlet duct 32 is provided on the top wall at the front of the washing zone 3. The air inlet end of the third air inlet duct 32 is connected to the junction of the first air inlet duct 12 and the second air inlet duct 22. With the above structure, it is convenient to control whether the washing zone 3 returns air according to the washing needs.

[0032] Washing zone 3 includes a first washing drum 301 and a second washing drum 302 arranged horizontally side by side. A third air inlet duct 32 has a Y-shaped structure. One branch of this Y-shaped structure is connected to the first washing drum 301, and a third air valve 03 is located near this branch. The other branch of the Y-shaped structure is connected to the second washing drum 302, and a fourth air valve 04 is located near this branch. This structure further subdivides the washing zone 3 to facilitate washing different types of clothing and meet users' more diverse washing needs.

[0033] The bottom of the first drum 1 is provided with a first vibration damper 10 and a second vibration damper 20, which are arranged at intervals and used to connect it to the side wall of the washing machine frame. The first air inlet pipe 12 passes through the space between the first vibration damper 10 and the second vibration damper 20 from bottom to top. With the above structure, the direction of the first air inlet pipe 12 can avoid the washing partition 3 and be arranged more compactly with the vibration damping structure, further improving the space utilization rate.

[0034] The fan 42 is arranged in a flat, vertical shape next to the heat pump module 41, meaning that the air outlet of the heat pump module 41 is located on its side wall near the fan 42, and the air inlet of the fan 42 faces the heat pump module 41. This structure further improves space utilization while shortening the return air formation time, thereby enhancing the drying effect.

[0035] With the washing machine structure of this embodiment, when it is necessary to dry the first drum 1, the second drum 2, the first washing tub 301, and the second washing tub 302 independently or simultaneously, it can be achieved through the cooperation of the first air valve 01, the second air valve 02, the third air valve 03, and the fourth air valve 04.

[0036] In this embodiment, the first drum 1, the second drum 2, and the washing zone 3 share a single drying system 4, which simplifies the overall structure and reduces costs. The installation space 100 between the first drum 1 and the second drum 2 is divided into two parts: the front part is used to install the washing zone 3 structure, and the rear part is used to install the drying system 4. This makes full use of the installation space 100 of the washing machine, thereby facilitating reasonable control of the overall height of the washing machine and making it convenient for users to operate.
