[0046] Although air conditioners currently have a spray-type self-cleaning function, the spray water source used for self-cleaning often has certain problems. For example, when condensed water or an external water source is used as cleaning water, the water source, water storage and collection method and other factors will cause the air conditioner condensed water to have poor water quality, which will have a certain impact on the cleaning results after using the water to clean the air conditioner. The present invention improves the air conditioner and provides a solution for collecting relatively clean condensed water in the indoor unit; the improved water collection device can be used to realize automatic water storage and drainage, and a filter device that can purify water quality is added therein, thereby ensuring the water quality of the cleaning water.

[0047] To further illustrate the technical solution of the present invention, Figure 1-Figure 9 As shown, the following specific embodiments are provided.

[0048] Example 1

[0049] like Figure 1-Figure 3 As shown, in this embodiment, a water collecting device 1 of an air conditioner is provided, and the water collecting device 1 includes: a water tank, a water valve assembly, a filtering device 17, etc.

[0050] A water tank is provided in the air conditioner and is used to store condensed water generated by the evaporator in the air conditioner. A water collection inlet 12 is formed at the upper portion of the water tank, and a drainage outlet 11 is formed at the lower portion of the water tank. The water valve assembly includes: a sealed water valve 18 provided at the drainage outlet 11; and a water valve driving device for driving the sealed water valve 18 to open / close. A filtering device 17 is provided at the inner bottom of the water tank and is used to filter impurities in the condensed water stored in the water tank.

[0051] Optionally, the evaporator includes: a front evaporator arranged on the front side of the air conditioner and a rear evaporator arranged on the rear side of the air conditioner. It should be noted that the front side refers to the side closer to people when facing the front of the air conditioner, and the rear side refers to the side farther from people when facing the front of the air conditioner. At this time, the water collection device 1 also includes: a first water collection channel 23 corresponding to the rear evaporator and a second water collection channel 21 corresponding to the front evaporator. The first water collection channel 23 is higher than the second water collection channel 21; the water collection inlet 12 is connected to the first water collection channel 23. The first water collection channel 23 is set at a higher position, and it collects the condensed water generated by the evaporator at a higher position, and its water quality is better than the condensed water quality in the evaporator at other locations. Based on the better selected water source, combined with the filter device 17 set inside the water tank, the clean water is further improved, and the cleaning effect of the air conditioner during self-cleaning is improved.

[0052] It should be noted that the first water collection channel 23 and the second water collection channel 21 can be arranged on the housing 2 of the air conditioner and formed integrally with the housing of the air conditioner, or can be independently arranged from the housing of the air conditioner.

[0053] like Figure 4-Figure 7 As shown, optionally, the water collecting device 1 further includes: a three-way structure 3.

[0054] The first end of the three-way structure 3 is connected to the drainage outlet 11; the second end of the three-way structure 3 is connected to the second water collection channel 21; and the third end of the three-way structure 3 is connected to the outside of the air conditioner. This method uses a simple three-way structure 3 in conjunction with a water tank to achieve multiple treatments such as collection, use and discharge of condensed water generated on the front evaporator and the rear evaporator.

[0055] Optionally, the water valve driving device includes: a driving motor 13 and a driving connecting rod 14. The driving motor 13 is used to provide power for the water valve driving device; the driving connecting rod 14 includes: a first connecting rod and a second connecting rod, the first end of the first connecting rod is connected to the driving motor 13, the second end of the first connecting rod is movably connected to the first end of the second connecting rod; the second end of the second connecting rod is movably connected to the sealing water valve 18.

[0056] Preferably, a top opening is formed at the top of the water tank in the water collecting device 1, and a water tank cover 15 corresponding thereto is also provided at the top opening. A through hole is provided on the water tank cover 15, wherein the driving motor 13 is provided at the top of the water tank, and the driving connecting rod 14 extends into the inside of the water tank through the through hole and is connected to the sealing water valve 18. By arranging the driving motor 13 at the top of the water tank and using the driving connecting rod 14 to penetrate it from the inside of the water tank to realize the opening and closing control of the sealing water valve 18, it is possible to reduce the overall size of the water collecting device 1 so that it does not occupy too much space after installation.

[0057] Preferably, an overflow port is provided on the water tank. The overflow port corresponds to the second water collecting channel 21. By adding an overflow port to the water tank, the water in the water tank will not be filled up or flow into other places of the air conditioner due to excessive water collection.

[0058] In some alternative embodiments, such as Figure 8 , Fig. 9 As shown, the water collection device 1 also includes a transfer water tank 3A arranged below the water tank. The inlet 3A1 of the transfer water tank is connected to the drainage outlet 11, and the outlet 3A2 of the transfer water tank is used to connect to the outside of the air conditioner through the drainage pipe 4. Preferably: the transfer water tank can be made of antibacterial material. The transfer water tank can be used instead of the three-way structure 3. In this case, other transfer water tank inlets can be set on the transfer water tank according to the number of water collection channels, such as the second transfer water tank inlet 3A3.

[0059] Example 2

[0060] In this embodiment, an air conditioner is provided, which adopts any one of the water collection devices 1 in Embodiment 1.

[0061] Optionally, the air conditioner further includes: a shell 2 and an evaporator assembly. The shell 2 has an installation cavity, and a first water collection channel 23 and a second water collection channel 21 are formed in the shell 2. The evaporator assembly includes a rear evaporator and a front evaporator. The rear evaporator is arranged at the rear side of the installation cavity and corresponds to the first water collection channel 23, and the front evaporator is arranged at the front side of the installation cavity and corresponds to the second water collection channel 21. Since the bottom side of the front evaporator of the air conditioner is lower than the bottom side of the rear evaporator, the corresponding setting position of the second water collection channel 21 is also lower than the setting position of the first water collection channel 23. At this time, the water tank in the water collection device 1 is arranged in the installation cavity, and the water collection inlet 12 of the water tank is connected to the first water collection channel 23.

[0062] like Figure 1-Figure 9 As shown, in the air conditioner of this embodiment, the electrical box assembly 0 is arranged on the right side of the air conditioner (from the front view after the air conditioner is installed). In order to ensure electrical safety, the water collecting device 1 is fixedly arranged on the other side of the air conditioner, i.e., on the left side of the air conditioner, through the water collecting device fixing plate 16 thereon. The water collecting device 1 is fixed on the bottom shell by three screws 5; the second water collecting channel 21 and the first water collecting channel 23 are respectively arranged at the front and rear positions on the bottom shell of the air conditioner housing 2, and a baffle (not shown in the figure) is arranged between the first water collecting channel 23 and the second water collecting channel 21 so that they are not connected to each other, and the condensed water of the front evaporator and the rear evaporator are respectively received.

[0063] The filter device 17 in the water collection device 1 can prevent large particles of impurities in the water tank from being sucked into the water pump and causing dirt and blockage. After the water tank cover 15 assembly is installed, the filter device 17 is located at the bottom of the water tank to better filter as much condensed water collected in the water tank as possible. The filtered condensed water can be sucked by a water pump and used for humidification, cleaning, etc. of the room.

[0064] The sealing water valve 18 is arranged at the bottom of the water tank corresponding to the drainage outlet 11, and the sealing valve assembly includes a valve body and a sealing ring. The closing and opening of the sealing water valve 18 is realized by the driving motor 13 installed on the water tank cover 15 through the action of the driving connecting rod 14. The driving motor 13 is preferably: a stepping motor. When the water tank needs to store water, the sealing water valve 18 is closed, and when the water in the water tank needs to be emptied, the sealing water valve 18 is opened, and the water is discharged through the drainage outlet 11.

[0065] In this embodiment, the water tank is used to store condensed water flowing in from the rear water channel. The evaporator condensed water on the rear water channel enters the water tank through the rear drain nozzle 24 on the bottom shell and the water collection inlet 12 of the water tank. When the sealing water valve 18 is opened, water is discharged from the drain outlet 11 of the water tank. When the sealing water valve 18 is not opened normally or the water tank stores too much water, the excess water can also be discharged through the overflow hole provided on the water tank. The water overflowing from the overflow port of the water tank flows to the front water channel on the bottom shell, and then is discharged to the second end of the three-way structure 3 or the transfer water tank through the front drain nozzle 22, and finally the condensed water is discharged to the outside through the drainage pipe 4 connected to the third end of the three-way structure 3 or the drain port of the transfer water tank.

[0066] The exemplary embodiments of the present disclosure are specifically shown and described above. It should be understood that the present disclosure is not limited to the detailed structures, configurations or implementations described herein; on the contrary, the present disclosure is intended to cover various modifications and equivalent configurations included in the spirit and scope of the appended claims.
