Description

Technical Field

[0001] This invention relates to the technical field of low-temperature evaporation devices for condensate, specifically a low-temperature evaporation device for improving the quality of condensate output. Background Technology

[0002] Condensate: This refers to liquid water formed from water vapor (i.e., gaseous water) through the condensation process. Condensate flows out from the drip tray below the evaporator of the indoor unit. Many existing refrigeration appliances, such as air conditioners and refrigerators, produce liquid condensate during use. This liquid condensate can only be transported to the evaporator by a water pump for evaporation. However, because the water droplets are relatively large, the evaporator's evaporation effect is minimal. Furthermore, since a water pump is necessary to transport the condensate to the evaporator, if the pump becomes clogged or damaged, it cannot process the condensate, and the condensate must be discharged directly through the drain. Direct discharge of condensate can easily cause environmental damage. The advantage of existing low-temperature evaporation devices is PTC heating. The evaporator does not work when there is no condensate, which saves energy and greatly extends the service life of the condensate evaporator. The water level sensor detects the water level in the collection tank, and the control circuit board starts the water pump and fan when the water level reaches the high level. This transports the condensate in the collection tank to the spray tank through the pipeline and sprays it onto the water curtain located in the fixed frame. The condensate can be removed by evaporation on the water curtain. Because the water-absorbing cloth of the evaporator has a large area in contact with the air and outdoor temperature, the condensate is quickly evaporated into the space, solving the problem of air conditioner condensate dripping.

[0003] For example, patent application CN106949634A discloses a condensate evaporator, comprising a shell, a water tank, a fan, a PTC heating element, a control circuit, an insulation base, and an LED indicator light assembly. The water tank has a vent pipe at its top, with its outlet passing through a vent on the shell. The fan is mounted on the shell and blows airflow through the vent. The control circuit includes a current detection circuit. This invention uses a PTC heating element whose resistance changes with temperature as the heating element, limiting the maximum temperature of the condensate evaporator and eliminating the possibility of dry burning. Furthermore, compared to existing condensate evaporators using PTC as the heating element, the PTC heating element of this invention does not operate when there is no condensate, saving energy and significantly extending the service life of the evaporator. During the condensate evaporation process, a small fan blows and disperses the generated water vapor, preventing secondary condensation on the equipment.

[0004] For example, patent application CN112696863A discloses a condensate evaporation device, including a water collection tank, a fixed frame, a water curtain, a spray tank, a water pump, pipelines, a fan, a water level sensor, and a control circuit board. The water level sensor detects the water level in the collection tank, and the control circuit board activates the water pump and fan when the water level reaches a high level. This transports the condensate from the collection tank through the pipelines to the spray tank, where it is sprayed onto the water curtain located in the fixed frame. The condensate is then removed by evaporation on the water curtain. This invention solves the problems or inconveniences encountered when removing condensate.

[0005] For example, patent application CN107436029A discloses an air conditioner condensate evaporator, including an upper water tray, a lower water tray, connecting strips, stainless steel columns, type 7 evaporation fins, and right-angle hooks. The upper and lower water trays are fixedly welded together at the back using connecting strips, and supported and fixed together at the front using stainless steel columns. Multiple right-angle hooks are installed under the permeation holes of the upper water tray; type 7 evaporation fins are hung directly from these hooks. When the condensate from the air conditioner flows from the condensate inlet pipe into the upper water tray, the condensate slowly accumulates and permeates through the permeation holes in the bottom plate of the upper water tray onto the absorbent cloth of each type 7 evaporation fin. Because the absorbent cloth of the evaporation fin has a large contact area with the air and outdoor temperature, the condensate evaporates quickly into the space, solving the problem of condensate dripping. This invention has a simple structure and is easy to use.

[0006] Existing low-temperature evaporation devices for condensate have the following problems:

[0007] 1. Because the air contains dust, smoke, microorganisms and chemical emissions, the condensed water will contain these substances, so the condensed water is not pure, which makes it difficult to improve the quality of the condensed water.

[0008] 2. Condensate consists of large, granular water droplets. Condensate tends to adhere to walls, does not easily accumulate, does not drip easily, and is inconvenient to collect.

[0009] 3. Over time, impurities accumulate in the filter screen used for filtering condensate, reducing its filtration efficiency. Failure to replace the filter screen will further reduce its effectiveness in filtering condensate, leaving the condensate still containing a large amount of impurities. Therefore, we propose a low-temperature evaporation device to improve the quality of condensate output and solve the problems mentioned above. Summary of the Invention

[0011] To achieve the above objectives, the present invention provides the following technical solution: a low-temperature evaporation device for improving the quality of condensate effluent, comprising a shell, a low-temperature evaporator, a collection box, a condensation box, and a condenser. A front cover is rotatably connected to the front side of the shell, and a ventilation opening is provided in the middle of the front cover. A cooling fan is fixedly connected to the middle of the ventilation opening. Fixing blocks are rotatably connected to both the left and right ends of the upper front side of the shell, and dustproof nets are fixedly connected to the upper left and right ends of the shell.

Connecting rods are fixedly connected to the left, right, front, and rear sides of the upper and lower ends of the guide column. A motor is fixedly connected to the left side of the upper end of the connecting rod. A lead screw is fixedly connected to the output shaft of the motor. A scraper is threaded to the outer side of the lead screw. A rotating rod is rotatably connected to the inner right side of the connecting rod.

[0013] A first filter screen is fixedly connected to the bottom end of the collection pipe. A conveying pipe is fixedly connected to the upper right side of the collection box, and a second filter screen is engaged in the middle of the conveying pipe.

[0016] Preferably, the air outlet of the blower extends through the bottom left side of the collection box.

[0017] Preferably, the outer side of the connecting rod is fixedly connected to the inner side of the collecting tube.

[0018] Preferably, the bottom end of the lead screw is rotatably connected to the upper surface of the connecting rod at the bottom end of the collecting tube.

[0024] 1. The collected untreated condensate water reaches the first filter screen through the collection pipe and the guide column. After the first filter screen filters out the impurities in the untreated condensate water, the untreated condensate water evaporates into mist after passing through the evaporator. It then passes through the conveying pipe and is filtered a second time by the second filter screen inside the conveying pipe, which helps to improve the quality of the condensate water.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figure 1-8 The present invention provides a technical solution: a low-temperature evaporation device for improving the quality of condensate effluent, comprising an outer shell 1, a front cover 2, a vent 3, a cooling fan 4, a fixing block 5, a dustproof net 6, a support plate 7, a low-temperature evaporator 8, a blower 9, a collection box 10, a collection pipe 11, a guide column 12, a connecting rod 13, a motor 14, a lead screw 15, a scraper 16, a rotating rod 17, a first filter screen 18, a conveying pipe 19, a second filter screen 20, a condensation box 21, a condenser 22, a water level sensor 23, a liquid outlet pipe 24, and a switching valve 25.

[0038] like Figure 1 Figure 2As shown, a front cover 2 is rotatably connected to the front side of the outer shell 1. Hinges are installed on the left and right sides of the bottom of the outer shell 1 and the front cover 2. A vent 3 is opened in the middle of the front cover 2. A cross-shaped bracket is fixedly connected to the rear side of the vent 3. A cooling fan 4 is fixedly connected to the middle of the front side of the cross-shaped bracket. The cooling fan 4 effectively dissipates heat for the entire low-temperature evaporation device. Fixing blocks 5 are rotatably connected to the left and right sides of the front end of the upper surface of the outer shell 1. The front end of the fixing block 5 is fixedly connected to the upper end of the front cover 2 by screws. By unscrewing the screws at the front end of the fixing block 5, the front cover 2 can be rotated from the top to the bottom, exposing the front side of the outer shell 1. The front cover 2 and the outer shell 1 are then covered. The screws at the front of the fixing block 5 are tightened to clamp and fix the front cover 2. Holes are opened in the middle of the upper left and right sides of the outer shell 1. Dustproof nets 6 are fixedly connected in the holes in the middle of the upper left and right sides of the outer shell 1. The holes in the upper left and right sides of the outer shell 1 are for heat dissipation, and the dustproof nets 6 are installed to prevent dust from entering the interior of the low-temperature evaporation device.

[0039] like Figure 1 As shown, a support plate 7 is fixedly connected to the bottom left side of the interior of the outer casing 1. A groove is opened on the front right side of the support plate 7. Sliding grooves are opened on the left and right sides of the groove on the right side of the support plate 7. A low-temperature evaporator 8 is slidably connected in the sliding grooves. A blower 9 is fixedly connected to the left side of the upper surface of the support plate 7. A collection box 10 is fixedly connected to the right side of the upper surface of the support plate 7. The bottom end of the collection box 10 is on the groove opened on the right side of the support plate 7. The collection box 10 is directly above the low-temperature evaporator 8. The low-temperature evaporator 8 can be pulled out from the front side of the support plate 7 for easy maintenance or replacement. The air outlet of the blower 9 passes through the bottom left side of the collection box 10 and is connected to the interior of the collection box 10. A collection pipe 11 is fixedly connected to the upper end of the collection box 10. The upper end of the collection pipe 11 passes through the upper left side of the outer casing 1. The bottom end of the collection pipe 11 is connected to the upper end of the collection box 10. A guide column 12 is installed in the middle of the interior of the collection pipe 11. Figure 8 As shown, connecting rods 13 are fixedly connected to the left, right, front, and rear sides of the upper and lower ends of the guide column 12. The outer side of the connecting rod 13 is fixedly connected to the inner side of the collecting pipe 11. A motor 14 is fixedly connected to the outer side of the upper surface of the connecting rod 13 on the left side of the upper end of the guide column 12. A lead screw 15 is fixedly connected to the output shaft of the motor 14. The upper end of the lead screw 15 passes through the connecting rod 13 and is connected to the output shaft of the motor 14. The bottom end of the lead screw 15 is rotatably connected to the upper surface of the connecting rod 13 on the left side of the bottom end of the guide column 12. A scraper 16 is threadedly connected to the outer side of the lead screw 15. Holes are opened in the middle of both the front and rear ends of the scraper 16. The holes in the middle of the front and rear ends of the scraper 16 facilitate the flow of untreated condensate into the collecting tank 10. The inner side of the scraper 16 is in contact with the outer side of the guide column 12, and the outer side of the scraper 16 is in contact with the inner side of the collecting pipe 11. Figure 1 Figure 3As shown, a rotating rod 17 is connected through the middle of the right end of the scraper 16. The upper and lower ends of the rotating rod 17 are rotatably connected to the inner side of the connecting rod 13 at the right end of the guide column 12. When the motor 14 runs, the output shaft of the motor 14 drives the lead screw 15 to rotate. Since the right end of the scraper 16 is restricted by the rotating rod 17, when the lead screw 15 rotates, the scraper 16, which is threaded to the lead screw 15, moves up and down on the lead screw 15. The scraper 16 moves up and down to scrape the untreated condensate on the collection pipe 11 and the guide column 12. Because the condensate is a large water droplet, it is easy to adhere to the side wall of the collection pipe 11 and the guide column 12. The scraper 16 moves up and down to scrape the untreated condensate on the collection pipe 11 and the guide column 12 downward into the collection box 10.

[0040] The bottom end of the collecting pipe 11 is fixedly connected to the first filter screen 18 by screws. The first filter screen 18 is funnel-shaped. The bottom end of the first filter screen 18 is fixedly connected to the outer side of the bottom end of the guide column 12 by screws. The first filter screen 18 can be removed from the collecting pipe 11 and the guide column 12 by simply unscrewing the screws that fix the first filter screen 18. The first filter screen 18 is used to perform the first filtration of the untreated condensate before evaporation, filtering out the impurities in the condensate. Afterwards, the condensate is collected in the collecting box 10 and evaporated into water mist or fog by the low-temperature evaporator 8.

[0041] A conveying pipe 19 is fixedly connected to the upper right side of the collection box 10. The conveying pipe 19 transports the evaporated condensate to the condensation box 21. A second filter screen 20 is snapped into the middle section of the conveying pipe 19. Figure 7 As shown, the upper end of the second filter screen 20 is provided with a protrusion. By holding the protrusion at the upper end of the second filter screen 20 and pulling the second filter screen 20 upward, the second filter screen 20 can be removed from the transmission pipe 19 and replaced. The condensed water in the water mist state is filtered for the second time by the second filter screen 20 and then sent to the condensation box 21. The rear side of the condensation box 21 is fixedly connected to the inner rear side of the outer shell 1. The bottom end of the condensation box 21 is fixedly connected to the condenser 22 by screws. The condenser 22 condenses the condensed water in the water mist state into liquid. The rear end of the right side of the condensation box 21 is fixedly connected to the water level sensor 23. The middle of the bottom right side of the condensation box 21 is fixedly connected to the liquid outlet pipe 24. The bottom end of the liquid outlet pipe 24 penetrates the bottom right side of the outer shell 1. The upper end of the liquid outlet pipe 24 is fixedly connected to the switch valve 25. The switch valve 25 controls the outflow of liquid condensed water.

[0042] The collection pipe 11 and the guide column 12 collect condensate. The scraper 16 moves up and down to hang the condensate on the collection pipe 11 and the guide column 12 to the bottom of the collection pipe 11 and the guide column 12. The untreated condensate is filtered by the first filter screen 18 and then enters the collection box 10. The low-temperature evaporator 8 is started, and the low-temperature evaporator 8 evaporates the condensate in the collection box 10 into water mist. The blower 9 is started to blow the water mist to the right, so that the water mist enters the conveying pipe 19. After the water mist is filtered twice by the second filter screen 20, it flows into the condensation box 21. The condenser 22 is started to condense the water mist back into liquid condensate. The water level sensor 23 senses the amount of liquid condensate in the condensation box 21. When a certain amount is reached, the switch valve 25 is opened, and the condensate is discharged from the outlet pipe 24. This step can improve the quality of the condensate. High-quality condensate has many uses, such as watering flowers and raising fish.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
