Condensate water collecting and processing structure of heating system

Abstract

This utility model provides a condensate collection and treatment structure for HVAC systems, relating to the field of HVAC condensate. It includes a fan and compressor rotatably connected inside a housing. Guided by a baffle plate, condensate easily falls into the filter tank. The condensate enters the collection tank through filter holes on the surface of the semi-cylindrical filter tank, and then passes through a diversion pipe before being stored in a transparent collection bottle. When one collection bottle is nearly full, a three-way valve is turned to allow condensate to enter another collection bottle. This facilitates continuous condensate collection during cleaning, improving the device's adaptability. Furthermore, by sliding the pressure block upwards and holding the protrusion on the side of the filter tank, the filter tank can be slid out for cleaning and maintenance. After the filter tank is reset, a spring supports the pressure block, causing the sliding column to slide downwards inside the collar. The pressure block limits the movement of the filter tank, improving the device's stability and cleanliness.

Description

Technical Field

[0001] This utility model relates to the field of HVAC condensate, and in particular to a condensate collection and treatment structure for HVAC systems. Background Technology

[0002] When heating, the outdoor unit acts as an evaporator, and its temperature is relatively low. Outdoor air condenses into water when it encounters the cold air. When the outdoor unit temperature is extremely low, the water turns into frost. When the air conditioner automatically defrosts, the frost melts, producing a lot of water, which is discharged from the bottom of the outdoor unit.

[0003] In the existing technology, such as the Chinese announcement number CN222165129U, there is a field of engineering HVAC condensate leak prevention technology, specifically a building engineering HVAC condensate leak prevention device, which includes engineering HVAC pipes, a device body and an outlet pipe. The engineering HVAC pipes have an engineering heating channel, and the device body is fixedly installed on the outside of the engineering heating channel. The device body is fixedly connected to the outlet pipe, and a collection pipe is fixedly installed on the outside of the device body. A protective fixing shell is fixedly installed on the outside of the device body, and a drainage component is connected to the protective fixing shell. The drainage component includes a motor, a first right-angle gear, a second right-angle gear and a water pump shaft. This device is fixedly installed at the bottom of the inner wall of the channel, which can collect the water droplets formed on the inner wall of the channel by the heating air passing through the channel, thereby protecting the building engineering HVAC, thus preventing the leakage of building engineering HVAC condensate and protecting the building engineering HVAC to improve its service life.

[0004] The aforementioned application achieves this through multiple components, collecting the water droplets formed on the inner wall of the channel by the radiator, thus protecting the device. However, this device is not easy to continuously collect condensate while cleaning it, which may affect the normal operation of the device and reduce its adaptability. This device is not easy to clean, which may reduce the cleanliness of the device and reduce the overall convenience and timeliness to a certain extent. Utility Model Content

[0005] This invention facilitates the cleaning of the device while continuously collecting condensate, thus improving the adaptability of the device. This invention also provides a convenient cleaning device, improving the stability and cleanliness of the device, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a condensate collection and treatment structure for a heating, ventilation, and air conditioning system, comprising a fan and a compressor rotatably connected inside a housing, an external heat exchanger tube fixedly connected to the inner wall of the housing, a guide plate fixedly connected to the inner top surface of the housing, a water collection tank fixedly connected to the inner bottom surface of the housing, a locking block fixedly connected to the top of the water collection tank, a filter groove slidably installed on the inner side of the locking block, a diversion pipe fixedly connected to the bottom of the water collection tank, water collection bottles threadedly fitted to both ends of the diversion pipe, a three-way valve installed inside the diversion pipe, and a support assembly fixedly connected to the outer wall of the housing;

[0007] The support assembly includes a collar, inside which a sliding column is slidably installed. A pressure block is fixedly connected to the bottom of the sliding column. The above-mentioned assembly facilitates the diversion, collection, and cleaning of condensate from the external heat exchanger tubes.

[0008] Preferably, a spring is slidably fitted onto the surface of the sliding column, with the upper and lower ends of the spring respectively abutting against the bottom surface of the collar and the top surface of the pressure block. This spring installation method provides the pressure block with a downward support force, improving the stability of the pressure block during installation.

[0009] Preferably, the front view of the sliding column is T-shaped. The shape of the sliding column makes it easier for the collar to limit the range of motion of the sliding column, thereby improving the stability of the sliding column during movement.

[0010] Preferably, the guide plate is positioned directly above the filter tank, and the external heat exchanger tube is installed through the side of the guide plate. The installation position of the guide plate facilitates the collection of condensate inside the device.

[0011] Preferably, the surface of the filter tank is provided with a plurality of filter holes at equal intervals, and the filter tank is in the shape of a semi-cylindrical cylinder. The shape of the filter tank facilitates the temporary storage of condensate inside the filter tank, thereby improving the adaptability of the device.

[0012] Preferably, one side of the filter groove is attached to the side of the pressure block, and a semi-circular protrusion is provided on one side of the filter groove. The connection method of the filter groove and the pressure block enables the pressure block to support and limit the filter groove, thereby improving the stability of the filter groove during installation.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the condensate is easily guided into the interior of the filter tank by the guide plate. The condensate enters the water collection tank through the filter holes on the surface of the semi-cylindrical filter tank, and is stored in the interior of the transparent water collection bottle after passing through the diversion pipe. When one water collection bottle is nearly full, the three-way valve is turned to allow the condensate to enter the other water collection bottle. This facilitates the continuous collection of condensate during the cleaning process and improves the adaptability of the device.

[0015] 2. In this utility model, by sliding the pressure block upward, holding the protruding block on the side of the filter tank, and sliding the filter tank out, the filter tank can be cleaned and maintained. When the filter tank is reset, the spring supports the pressure block, causing the sliding column to slide downward inside the collar. The pressure block has a limiting effect on the filter tank, which improves the stability of the device and the cleanliness of the device. Attached Figure Description

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Please see Figures 1-4 This utility model provides a technical solution: a condensate collection and treatment structure for a heating and ventilation system, including a fan 2 and a compressor 3 rotatably connected inside a shell 1, an external heat exchanger tube 4 fixedly connected to the inner wall of the shell 1, a guide plate 5 fixedly connected to the inner top surface of the shell 1, a water collection tank 6 fixedly connected to the inner bottom surface of the shell 1, a locking block 7 fixedly connected to the top of the water collection tank 6, a filter tank 8 slidably installed on the inner side of the locking block 7, a diversion pipe 10 fixedly connected to the bottom of the water collection tank 6, water collection bottles 11 threadedly fitted at both ends of the diversion pipe 10, a three-way valve 12 installed inside the diversion pipe 10, and a support assembly 13 fixedly connected to the outer wall of the shell 1.

[0024] The support assembly 13 includes a collar 131, and a sliding column 132 is slidably installed inside the collar 131. A pressure block 133 is fixedly connected to the bottom of the sliding column 132. The above-mentioned assembly facilitates the diversion, collection and cleaning of condensate from the external heat exchanger tube 4.

[0025] like Figure 4 As shown, a spring 134 is slidably sleeved on the surface of the sliding column 132. The upper and lower ends of the spring 134 abut against the bottom surface of the collar 131 and the top surface of the pressure block 133, respectively. The installation method of the spring 134 provides the pressure block 133 with a downward support force, which improves the stability of the pressure block 133 during installation.

[0026] like Figure 4 As shown, the front view of the slide bar 132 is T-shaped. The shape of the slide bar 132 makes it easier for the collar 131 to limit the range of motion of the slide bar 132, thereby improving the stability of the slide bar 132 during movement.

[0027] like Figure 3 As shown, the guide plate 5 is located directly above the filter tank 8, and the external heat exchanger tube 4 is installed through the side of the guide plate 5. The installation position of the guide plate 5 is designed to facilitate the collection of condensate inside the device.

[0028] like Figure 3 As shown, a number of filter holes 9 are evenly spaced on the surface of the filter tank 8. The filter tank 8 is semi-cylindrical in shape. The shape of the filter tank 8 facilitates the temporary storage of condensate inside the filter tank 8, which improves the adaptability of the device.

[0029] like Figure 1 and Figure 4 As shown, one side of the filter tank 8 is attached to the side of the pressure block 133, and a semi-circular protrusion is provided on one side of the filter tank 8. The connection method of the filter tank 8 and the pressure block 133 enables the pressure block 133 to support and limit the filter tank 8, thereby improving the stability of the filter tank 8 during installation.

[0030] The usage and working principle of this device are as follows: When heating, the outdoor unit acts as an evaporator and the temperature is low. When the outdoor air encounters the cold, it will condense into water. At this time, the condensate attached to the surface of the heat exchanger tube 4 is guided by the guide plate 5 to fall into the interior of the filter tank 8. The condensate enters the water collection tank 6 through the filter holes 9 on the surface of the semi-cylindrical filter tank 8. At the same time, after passing through the diversion pipe 10, it is stored in the interior of the transparent water collection bottle 11. When one water collection bottle 11 is almost full, turn the three-way valve 12 to let the condensate enter the interior of the other water collection bottle 11.

[0031] Based on this, after the device has been working for a long time, impurities may accumulate in the filter tank 8. At this time, slide the pressure block 133 upward, hold the protrusion on the side of the filter tank 8, slide and pull out the filter tank 8 to clean and maintain it. After the filter tank 8 is reset, the spring 134 supports the pressure block 133, causing the slide column 132 to slide downward inside the collar 131. The pressure block 133 has a limiting effect on the filter tank 8, which improves the stability of the device.

[0032] The compressor 3 and external heat exchanger tube 4 used in this application are Gree QXA-B096 parts, which are common conventional equipment on the market and are known to those skilled in the art. In this application, the above equipment is used in a conventional manner without any improvement to its structure and function. As for their settings, installation and electrical connection methods, those skilled in the art can debug and operate them according to the corresponding product instruction manuals, so they will not be described in detail here.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
