DETAILED DESCRIPTION

[0032] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the utility model. Instead, they are only examples of devices and methods consistent with some aspects of the utility model as detailed in the attached claims.

[0033] The present embodiment is described in detail below in conjunction with the accompanying drawings. The following embodiments and examples may be combined with each other unless there is any conflict.

[0034] According to an exemplary embodiment, Figure 1-Figure 6As shown, this embodiment proposes an example of a double-drum laundry processing device, referring to Figure 1-Figure 4 The double drum laundry processing device of this embodiment includes a frame assembly 1, a drum assembly 2 and a heat pump system 3. The frame assembly 1 is formed by enclosing a plurality of frame plates. In one example, referring to Figure 1 The frame assembly 1 includes a rear frame plate 15, a left frame plate 13 and a right frame plate 14 fixed to the left and right ends of the rear frame plate 15, and an upper frame plate 11 and a lower frame plate 12 fixed to the upper and lower ends of the rear frame plate 15. The drum assembly 2 is arranged on the frame assembly 1, and the drum assembly 2 includes a first drum assembly and a second drum assembly stacked from top to bottom, and at least one of the first drum assembly and the second drum assembly has both washing and drying functions. Exemplarily, the first drum assembly and the second drum assembly both have washing and drying functions, and the first drum assembly and the second drum assembly share a set of heat pump system 3.

[0035] The first cylinder assembly includes a first outer cylinder 21 and a first inner cylinder (not shown in the figure), and the first inner cylinder can rotate in the first outer cylinder 21. The second cylinder assembly includes a second outer cylinder 22 and a second inner cylinder (not shown in the figure), and the second inner cylinder can rotate in the second outer cylinder 22. The first outer cylinder 21 is connected to the upper frame plate 11 through a plurality of first hanging springs 6 at the top, and is connected to the middle of the frame assembly 1 through a plurality of first dampers 4 at the bottom. The second outer cylinder 22 is connected to the middle of the frame assembly 1 through a plurality of second hanging springs 7 at the top, and is connected to the lower frame plate 12 through a second damper 5 at the bottom.

[0036] like Figure 1-Figure 6 As shown, the heat pump system 3 is used to provide drying heat to the first drum assembly and / or the second drum assembly to realize the drying function of the first drum assembly and / or the second drum assembly. It is further preferred that the heat pump system can choose to provide drying heat to the first drum assembly or the second drum assembly separately according to the washing and drying program requirements of the first drum assembly and the second drum assembly (at this time, only one of the first drum assembly and the second drum assembly is executing the drying program), and can also provide drying heat to the first drum assembly and the second drum assembly at the same time (at this time, both the first drum assembly and the second drum assembly are executing the drying program).

[0037] Specifically, refer to Figure 1-Figure 4The heat pump system 3 includes a two-device assembly 31 and a compressor 32. The two-device assembly 31 is formed by integrating a condenser and an evaporator. The two-device assembly 31 includes a two-device box 311 and a two-device component 312 arranged in the two-device box 311. The two-device component 312 includes an evaporator (not shown in the figure) and a condenser (not shown in the figure). The condenser and the evaporator are obtained by inserting fins through copper tubes, and are used to generate heat and absorb heat respectively. The two-device assembly 31 is located between the first outer cylinder 21 and the second outer cylinder 22. For example, the two-device assembly 31 is connected to the middle part of the frame by screws and sheet metal parts. The compressor 32 is located at the side and rear of the first outer cylinder 21, or at the side and rear of the second outer cylinder 22, so as to solve the problem that the heat dissipation of the compressor 32 is difficult, and the drying performance and overall height of the double-cylinder heat pump washer-dryer are difficult to choose.

[0038] The two-device assembly 31 and the compressor 32 are preferably arranged separately. Compared with arranging the compressor 32 near the two-device assembly 31, the installation space of the two-device assembly 31 is increased, which is conducive to increasing the heat exchange area of ​​the evaporator and the condenser in the two-device assembly 31, thereby improving the heat exchange efficiency. In addition, by arranging the compressor 32 at the side and rear of the first outer cylinder 21 or the second outer cylinder 22, the space between the rear frame plate 15 and the first outer cylinder 21 and the second outer cylinder 22 is reasonably utilized without increasing the height of the main unit. At the same time, the installation space of the compressor 32 is increased, which is conducive to the heat dissipation of the compressor 32, thereby improving the operating efficiency of the compressor 32.

[0039] Further, in some embodiments, referring to Figure 1-Figure 4 The compressor 32 is located on the diagonal line of the frame assembly 1, and the frame assembly 1 has a rectangular parallelepiped frame structure. Figure 2 In the orientation shown, the position of the first outer cylinder 21 to the side and rear and located on the diagonal of the frame assembly 1 includes the upper left corner and the upper right corner of the frame assembly 1, and the position of the second outer cylinder 22 to the side and rear and located on the diagonal of the frame assembly 1 includes the lower left corner and the lower right corner of the frame assembly 1. Since the space between the frame assembly 1 and the cylinder body is relatively large in the upper left corner, upper right corner, lower left corner and lower right corner of the frame assembly 1, the compressor 32 can be installed at any position of the upper left corner, upper right corner, lower left corner and lower right corner of the frame assembly 1. The larger installation space is conducive to the heat dissipation of the compressor 32, so that the compressor 32 can be operated for a long time at a higher frequency, ensuring that the drying performance is not affected by overheating of the compressor 32.

[0040] In some embodiments (not shown in the figure), the frame assembly 1 includes an upper frame plate 11, which is located above the first outer cylinder 21. When the compressor 32 is located at the side and rear of the first outer cylinder 21, the compressor 32 is fixed on the upper frame plate 11, or the compressor 32 is fixed on the first outer cylinder 21, or the compressor 32 is fixed on the upper frame plate 11 and the first outer cylinder 21.

[0041] In some embodiments, reference Figure 1-Figure 4 The frame assembly 1 includes a lower frame plate 12, which is located below the second outer cylinder 22. When the compressor 32 is located at the side and rear of the second outer cylinder 22, the compressor 32 is fixed to the lower frame plate 12, or the compressor 32 is fixed to the second outer cylinder 22, or the compressor 32 is fixed to the lower frame plate 12 and / or the second outer cylinder 22. For example, refer to Figure 1 The lower frame plate 12 is provided with fixing bolts, and the compressor 32 is fixed to the lower frame plate 12 by fixing screws.

[0042] In some embodiments, reference Figure 2 and Figure 3 The setting position of the compressor 32 can be adjusted according to the space in which it is set. When the compressor 32 is located at the diagonal of the frame assembly 1, the space in the height direction of the position where the compressor 32 is set is larger than the space in the width direction. Therefore, setting the compressor 32 as a vertical compressor 32 is more conducive to the rational use of space.

[0043] In some embodiments, the air intake pipe of the compressor 32 and the air outlet pipe of the evaporator are detachably connected, and the exhaust pipe of the compressor 32 and the air inlet pipe 331 of the condenser are detachably connected to solve the problem that the copper pipe line is too long due to welding and is inconvenient to install.

[0044] In some embodiments, reference Figure 2-Figure 5The compressor 32 is located at the rear side of the second outer tube 22, preferably at the right rear side. The suction pipe 342 of the compressor is detachably connected to the exhaust pipe 341 of the evaporator through the rear side of the second outer tube 22 through the first connector 36, and the suction pipe 342 of the compressor and the exhaust pipe 341 of the evaporator form a first refrigerant pipeline 34. The exhaust pipe 332 of the compressor is detachably connected to the intake pipe 331 of the condenser through the second connector 35 through the rear side of the second outer tube 22, and the exhaust pipe 332 of the compressor and the intake pipe 331 of the condenser form a second refrigerant pipeline 33. In this embodiment, the first refrigerant pipeline 33 and the second refrigerant pipeline 34 are connected to the two-device assembly 31 and the compressor 32 from the rear side of the second outer tube 22, thereby shortening the pipeline length of the first refrigerant pipeline 33 and the second refrigerant pipeline 34, which is conducive to reducing production costs. In this embodiment, the compressor 32 and the two-device assembly 31 can be installed separately and then connected together through the second connector 35 and the first connector 36, so as to avoid the occurrence of open flames during welding connection. It can be assembled on the production line, is easy to install, and has high reliability. At the same time, the air inlet pipe 331 of the condenser is detachably connected to the exhaust pipe 332 of the compressor, and the exhaust pipe 341 of the evaporator is detachably connected to the suction pipe 342 of the compressor through the first connector 36, which solves the problem of the first refrigerant pipeline 33 and the second refrigerant pipeline 34 being too long and inconvenient to install due to conventional welding methods. Exemplarily, the first connector 36 and / or the second connector 35 are Locke rings.

[0045] In some embodiments, reference Figure 1-Figure 4 The heat pump system 3 further includes a rear air duct component 8, which is used to drive the humid and hot air in the first outer cylinder 21 and the second outer cylinder 22 to be discharged, and to transport the discharged humid and hot air to the two-device assembly 31 for condensation.

[0046] In some embodiments, reference Figure 1-Figure 4The heat pump system 3 includes a front air duct component 9, which is used to transport the hot air generated by the two-device assembly 31 to the first outer cylinder 21 and the second outer cylinder 22. The first outer cylinder 21 includes a first door seal 213, and the second outer cylinder 22 includes a second door seal 223. The first door seal 213 is provided with a first air inlet 212, and the second door seal 223 is provided with a second air inlet 222. The two-device assembly 31 has two-device air outlets, and the two-device air outlets generate hot air. The two-device air outlets are connected to the first air inlet 212 and the second air inlet 222 through the front air duct component 9. The front air duct component 9 includes a first part and a second part. The two-device air outlets are connected to the first air inlet 212 through the first part, and the two-device air outlets are connected to the second air inlet 222 through the second part, so that the clothes in the first cylinder assembly and the second cylinder assembly can be dried. In actual operation, the first part and the second part can be controlled to be turned on and off to realize that the air outlets of the two devices deliver hot air to the first outer drum 21 and the second outer drum 22 separately, or deliver hot air to the first outer drum 21 and the second outer drum 22 simultaneously. The first air inlet 212 is arranged at the first door seal 213, and the second air inlet 222 is arranged at the second door seal 223, which is conducive to the hot air from the first door seal 213 and the second door seal 223 to diffuse into the first outer drum 21 and the second outer drum 22, thereby improving the uniform drying effect of the clothes in the first drum assembly and the second drum assembly (as known to those skilled in the art, the hot air of the first outer drum 21 enters the first inner drum through the holes on the wall of the first inner drum to dry the clothes, and the hot air of the second outer drum 22 enters the second inner drum through the holes on the wall of the second inner drum to dry the clothes).
