DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0021] To enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solution in the embodiments of this application in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0022] As Figures 1-4 shown, this application provides a condensate discharge device for an air source heat pump system, including: a water receiving tray 1, a filtering mechanism 3, and a drain pipe 4. An outlet pipe 2 is installed at the bottom of the water receiving tray 1 and is connected to it in communication. The water receiving tray 1 is used to receive the condensate generated in the air source heat pump system. A valve is installed on the outlet pipe 2. The filtering mechanism 3 is connected to the end of the outlet pipe 2. The filtering mechanism 3 includes a connecting cylinder 31 and a turntable 35. The turntable 35 is located inside the connecting cylinder 31 and is rotatably connected to the connecting cylinder 31. A pair of communication holes 38 are provided on the turntable 35. Filtering elements 37 are detachably installed on the inner walls of the pair of communication holes 38. The drain pipe 4 is installed at the bottom of the connecting cylinder 31 and is in communication with the connecting cylinder 31; wherein, the filtering mechanism 3 further includes a motor 32 for driving the turntable 35 to rotate at an angle. The motor 32 can be fixed to the top of the connecting cylinder 31 by bolts, and the output end of the motor 32 penetrates through the connecting cylinder 31 and is fixedly connected to the turntable 35.

[0023] This solution is a device for discharging the condensate generated during the use of an air source heat pump system. Specifically, the condensate generated by the air source heat pump system is discharged into the water receiving tray 1, and then discharged into the filtering mechanism 3 through the outlet pipe 2. The condensate is filtered by the filtering elements 37 inside the communication holes 38. Subsequently, the filtered condensate is discharged through the drain pipe 4 to ensure that the condensate is clean before use and save water resources. However, as impurities continuously accumulate on the surface of the filtering elements 37, the valve on the outlet pipe 2 can be closed and the motor 32 can be started to control the turntable 35 to rotate 180°. After the positions of the two filtering elements 37 are swapped, the valve on the outlet pipe 2 is opened. At this time, the filtering element 37 located below the outlet pipe 2 can filter the condensate. The staff can take out the idle filtering element 37 for replacement, and during the replacement process, the device can still discharge the condensate, ensuring the continuous operation and efficiency of the air source heat pump system.

[0024] It should be noted that the outlet pipe 2 and the drain pipe 4 are coaxially arranged. By driving the turntable 35 to rotate through the provided motor 32, the two communication holes 38 are alternately coaxially arranged with the outlet pipe 2 and the drain pipe 4.

[0025] As Figures 2-3As shown in the figure, a maintenance hole 33 is provided at the top of the connecting cylinder 31. The position of the maintenance hole 33 corresponds to the position of one of the communication holes 38. A cover plate 34 is rotatably connected to the top of the connecting cylinder 31, and the cover plate 34 covers the top opening of the maintenance hole 33.

[0026] In this embodiment, by opening the cover plate 34, the internal filter element 37 and the maintenance hole 33 are exposed. The idle filter element 37 can be taken out through the maintenance hole 33 for cleaning. After cleaning, the filter element 37 is reinstalled into the communication hole 38 for next use.

[0027] As Figure 4 shown in the figure, the filter element 37 includes a first filter disc 371 and a second filter disc 372. A pull ring 373 is installed on the top of the first filter disc 371, which is convenient for taking out the filter element 37 from the communication hole 38. The first filter disc 371 and the second filter disc 372 are connected by bolts, and the first filter disc 371 and the second filter disc 372 form a chamber together, and the chamber is filled with activated carbon.

[0028] In this embodiment, the provided first filter disc 371 and second filter disc 372 are used to intercept impurities in the condensed water, and the activated carbon is used to absorb harmful substances in the condensed water. In addition, by using bolts to connect the first filter disc 371 and the second filter disc 372, it is convenient to replace the activated carbon in the chamber.

[0029] As Figures 2-3 shown in the figure, retaining rings 36 are installed on the inner walls of both communication holes 38. The filter element 37 is located on top of the retaining ring 36. A magnetic block is installed on the top of the retaining ring 36, and a magnet adsorbed to the magnetic block is installed at the bottom of the second filter disc 372.

[0030] In this embodiment, the provided retaining ring 36 is used to support the filter element 37. In addition, through the mutual cooperation of the magnetic block and the magnet, the position of the filter element 37 can be fixed, improving the filtering stability.

[0031] Working principle:

[0032] The condensed water generated by the air source heat pump system is discharged into the water receiving tray 1, and then discharged into the filtering mechanism 3 through the water outlet pipe 2. The condensed water is filtered by the filter element 37 inside the communication hole 38, and then the filtered condensed water is discharged through the drain pipe 4 to ensure that the condensed water is clean before use, saving water resources. However, as impurities continuously accumulate on the surface of the filter element 37, the valve on the water outlet pipe 2 can be closed and the motor 32 can be started to control the turntable 35 to rotate 180°, so that the positions of the two filter elements 37 are swapped, and then the valve on the water outlet pipe 2 is opened. At this time, the filter element 37 located below the water outlet pipe 2 can filter the condensed water. In addition, the cover plate 34 can be opened to expose the internal filter element 37 and the maintenance hole 33, and the idle filter element 37 can be taken out through the maintenance hole 33 for cleaning. After cleaning, the filter element 37 is reinstalled into the communication hole 38 for next use.

[0033] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
