DETAILED DESCRIPTION

[0033] The following will be further explained in detail with reference to the accompanying drawings. Figures 1-8 The present application is further explained in detail.

[0034] Embodiment 1

[0035] Referring to Figures 1-4 , a condensate water collecting structure for an evaporator includes a rack 1, and a heat pump module 2 is installed in the rack 1, wherein the heat pump module 2 includes an evaporator 3. A heat absorption cavity 4 is arranged in the rack 1, and the evaporator 3 is installed in the heat absorption cavity 4. An air return port 5 and an air exhaust port 6 are respectively arranged in the side wall of the rack 1, and the air return port 5 and the air exhaust port 6 are respectively connected with the heat absorption cavity 4. A guide plate 7 is fixedly connected in the heat absorption cavity 4, one end of the guide plate 7 is communicated with a water collecting tank 8, the water collecting tank 8 is installed on one side of the rack 1, and the bottom surface of the water collecting tank 8 is fixedly communicated with a water collecting pipe 9. A filtering mechanism is further installed in the water collecting tank 8, and the filtering mechanism is used for filtering impurities in liquid drops.

[0036] The working process of the evaporator 3 is a heat absorption process. When high-temperature air passes through the evaporator 3 in the heat absorption cavity 4, the low-temperature refrigerant flowing in the evaporator 3 exchanges heat with the high-temperature hot air, thereby reducing the temperature of the high-temperature air, and achieving the effect of refrigeration. It should be noted that in the process of refrigeration of high-temperature air, water vapor in the air will condense to form liquid drops. The liquid drops are collected in the direction close to the guide plate 7 under the action of gravity and air blowing, and then collected in the water collecting tank 8 along the guide plate 7, and finally discharged through the water collecting pipe 9. The liquid drops in the water collecting tank 8 can be used for secondary utilization of water, such as irrigation, etc.

[0037] In the embodiment, the heat pump module 2 further includes a compressor 10, a condenser 11, an expansion valve 12, and a gas-liquid separator 13. The compressor 10, the condenser 11, the expansion valve 12, the evaporator 3, and the gas-liquid separator 13 are sequentially connected in circulation through pipelines. ​

[0038] Specifically, referring to Figure 5 , the filtering mechanism comprises a filter screen 14. The inner wall of the water collecting tank 8 is fixedly provided with a support seat 15, the filter screen 14 is installed in the water collecting tank 8, and the filter screen 14 abuts against the top surface of the support seat 15.

[0039] In addition, in order to facilitate the fixation of the filter screen 14, the water collecting tank 8 is further provided with a fixation assembly, and the fixation assembly comprises a plurality of fixation screws 16. The plurality of fixation screws 16 are annularly and uniformly distributed on the top surface of the filter screen 14, the fixation ends of the plurality of fixation screws 16 respectively penetrate through the filter screen 14, and the fixation ends of the plurality of fixation screws 16 are threadedly connected with the support seat 15.

[0040] When the filter screen 14 needs to be fixed, the filter screen 14 is first overlapped on the top surface of the support seat 15, then the fixation screws 16 are respectively penetrated through the filter screen 14, and the fixation ends of the fixation screws 16 are respectively threadedly connected with the support seat 23. Under the action of the fixation screws 16, the filter screen 14 is fixed in the water collecting tank 8. Conversely, when the filter screen 14 needs to be disassembled and replaced, the plurality of fixation screws 16 are sequentially loosened, and then the filter screen 14 is taken out and replaced.

[0041] Referring to Figure 4 , in order to reduce the odor in the water collecting tank 8 from being emitted into the air, or reduce the dust such as fallen leaves from polluting the liquid drops, the opening end of the water collecting tank 8 is open, and the open end cover is provided with a top cover 17. The side of the top cover 17 facing the rack 1 is provided with a clearance hole 18, and one end of the guide plate 7 close to the water collecting tank 8 is overlapped on the clearance hole 18. The side wall of the water collecting tank 8 is further fixedly connected with a buckling member 19, and the buckling member 19 is a commonly used locking member in the art.

[0042] When the opening end of the water collecting tank 8 needs to be closed, the top cover 17 is first covered on the opening end of the water collecting tank 8, and then the top cover 17 is locked by the buckling member 19 to complete the covering of the top cover 17. By covering the top cover 17, the odor in the water collecting tank 8 is reduced from being emitted into the air. By providing the clearance hole 18, the liquid drops are guided along the guide plate 7 and finally collected in the water collecting tank 8 through the clearance hole 18.

[0043] It is worth mentioning that, referring to Figure 6 , the bottom surface of the guide plate 7 is fixedly connected with two connecting plates 20 in symmetry, and the two connecting plates 20 are fixedly connected with a heating wire 21. The connecting plate 20 is an insulating plate, and the heating wire 21 is electrically connected with a power supply.

[0044] When the high-temperature gas is cooled and the temperature continues to decrease, part of the liquid drops may exist in the form of frost. At this time, the heating wire 21 is electrically connected, the heating wire 21 heats the guide plate 7, the guide plate 7 is heated to melt the frost, and then the liquid drops are finally collected in the water collecting tank 8.

[0045] It should be noted that, see Figure 4 The cross section of the guide plate 7 is arranged in an inner arc, and the inner arc direction is towards the direction close to the water collecting groove 8.

[0046] By arranging the guide plate 7 in an inner arc, the cooled air carrying liquid droplets flows along the surface of the guide plate 7, reducing the splashing of liquid droplets on the guide plate 7 and improving the stability of the liquid droplets collected in the water collecting groove 8.

[0047] The working principle of the condensate water collecting structure for the evaporator:

[0048] The working process of the evaporator 3 is a heat absorption process. When high-temperature air passes through the evaporator 3 in the heat absorption cavity 4, the low-temperature refrigerant flowing in the evaporator 3 exchanges heat with the high-temperature hot air, thereby reducing the temperature of the high-temperature air to achieve the effect of refrigeration. It should be noted that during the refrigeration process of high-temperature air, water vapor in the air will condense to form liquid droplets. The liquid droplets are collected in the direction close to the guide plate 7 under the action of their own gravity and the flow of air blowing, and then collected in the water collecting groove 8 along the guide plate 7, and finally discharged through the water collecting pipe 9. The liquid droplets in the water collecting groove 8 can be used for secondary use of water, such as irrigation, etc.

[0049] It should be noted that when the high-temperature gas is cooled and the temperature continues to decrease, part of the liquid droplets may be frozen. At this time, the heating wire 21 is turned on, the heating wire 21 heats the guide plate 7, and the guide plate 7 is heated to melt the frost, and then the liquid droplets are finally collected in the water collecting groove 8.

[0050] Embodiment two, the difference between embodiment one is that the structure of the fixed assembly is different.

[0051] Specifically, see Figure 7 and Figure 8 The fixed assembly includes a stop block 22, and the water collecting groove 8 is fixedly connected with a support 23 on both sides. The support 23 is slidably installed with a pull rod 24. The number of stop blocks 22 corresponds to the number of pull rods 24. The stop block 22 is fixedly connected to one end of the pull rod 24, and one end of the stop block 22 penetrates and extends into the water collecting groove 8. One end of the stop block 22 abuts against the top surface of the filter screen 14.

[0052] In addition, in order to cooperate with the movement of the pull rod 24, the support 23 is also provided with an elastic member, which is a spring 25. The spring 25 is sleeved on the pull rod 24, and one end of the spring 25 is fixedly connected with the side wall of the pull rod 24, and the other end of the spring 25 is fixedly connected with the inner wall of the support 23.

[0053] When the filter screen 14 needs to be disassembled and replaced, the pull rod 24 is pulled away from the water collecting tank 8, the pull rod 24 drives the abutting block 22 to move away from the water collecting tank 8, at this time, the pull rod 24 extrudes the spring 25, and the abutting block 22 releases the restriction on the filter screen 14, thereby achieving the disassembly and replacement of the filter screen 14. When the pull rod 24 is released, the spring 25 releases the elastic force and drives the pull rod 24 to move towards the water collecting tank 8, the pull rod 24 drives the abutting block 22 to move towards the water collecting tank 8, at this time, the abutting block 22 abuts against the top surface of the filter screen 14, and the filter screen 14 is restricted on the support 23.

[0054] In summary, the liquid droplets are guided out of the rack 1 by the guide plate 7, thereby reducing the accumulation of liquid droplets in the rack 1, improving the dryness of the working environment of the heat pump module 2, and improving the stability of the operation of the heat pump module 2.

[0055] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application should be covered within the protection scope of the present application.
