The water pan 100 in this embodiment is disposed below the heat exchange assembly 110, and the middle of the water pan 100 is provided with an air vent 1, and the air vent 1 is usually communicated with the air exhaust duct to generate negative pressure in the space between the heat exchange assembly 110 and the water pan 100. Air outside the heat exchange assembly 110 is attracted and penetrates through the heat exchange assembly 110, in the process, the air is fully contacted with the heat exchange assembly 110 to generate condensed water, the condensed water flows to the water receiving tray 100 along the surfaces of the first heat exchanger 111 and the second heat exchanger 112 under the action of gravity, airflow pressure and hydrophilic adsorption force of fins on the heat exchangers, and the air penetrates through the heat exchange assembly 110 and is discharged along the air holes 1 of the water receiving tray 100.

The heat exchange assembly 110 includes a first heat exchanger 111 and a second heat exchanger 112 diverged along a predetermined angle, and an included angle between the first heat exchanger 111 and the second heat exchanger 112 may be 60 °, and the included angle therebetween may be other angles.

Referring to fig. 3, the water pan 100 may be a square plate-shaped structure, the air vent 1 is formed in the middle of the water pan, the air vent 1 may be square or in other shapes, the water pan 100 may include a first water receiving portion 11, a low side water receiving portion 12, a second water receiving portion 13, and a high side connecting portion 14, which are sequentially connected around the air vent 1, and the first water receiving portion, the low side water receiving portion 12, the second water receiving portion 13, and the high side connecting portion 14 may be integrally formed or may be formed separately and then connected into a whole by welding, bolting, and the like. The height of the high-side connection portion 14 is higher than that of the low-side connection portion, so that the condensed water on the first water receiving portion 11 and the second water receiving portion 13 tends to flow to the low-side connection portion and finally converge on the drain port 121 at the bottom of the low-side water receiving portion 12 to flow out of the drain pan 100, and the drain port 121 may extend downward from the bottom of the low-side water receiving portion 12 to form a tubular interface to facilitate external connection of a drain pipe.

Referring to fig. 4 and 5, the maintenance assembly 2 may be a plate-shaped structure, and is connected between the side of the heat exchange assembly 110 and the low side water receiving portion 12, because the shape and structure of the side of the heat exchange assembly 110 are substantially inverted "V" shape, the maintenance assembly 2 may be triangular and connected to the side of the heat exchange assembly 110 and the low side connecting portion of the water receiving tray 100, and the maintenance assembly 2 relatively isolates the space between the heat exchange assembly 110 and the water receiving tray 100 from the outside, it can be understood that, in order to ensure isolation, a fixed or detachable sealing plate structure may be disposed on the side of the heat exchange assembly 110 away from the maintenance assembly 2, and the sealing plate structure is connected to the side of the heat exchange assembly 110 away from the maintenance assembly 2 and the high side connecting portion 14 of the water receiving tray 100, so as to ensure that most of air passes through the heat exchange assembly 110 and is fully contacted therewith, and then is discharged through the vent 1.

The maintenance assembly 2 is provided with maintenance holes 211, and the maintenance holes 211 can be opened or closed, so that when the water pan 100 and the heat exchange assembly 110 work normally, the maintenance holes 211 can be closed to ensure that the air outlet side between the water pan 100 and the heat exchange assembly 110 is relatively sealed with the external air return side; when the water pan 100 needs to be overhauled, the maintenance hole 211 on the maintenance component 2 can be opened, and the water pan 100 and the water outlet 121 on the water pan 100 can be maintained through the maintenance hole 211, so that the reliability and the maintenance convenience of the water pan 100 are improved.

In one of the embodiments, at least a portion of the maintenance assembly 2 is provided as a transparent portion.

The transparent portion of the maintenance assembly 2 may be made of a transparent material (e.g., glass, plastic, etc.), and the transparent portion may be disposed at any position of the maintenance assembly 2, as long as the maintenance person can observe the drain opening 121 from the side of the maintenance assembly 2 away from the drain opening 121. Maintenance personnel can see the water collector 100 and the working condition of the position of the water outlet 121 on the water collector 100 through the transparent part from one side, far away from the water outlet 121, of the maintenance assembly 2, so that the blockage condition of the water outlet 121 can be found in time, the maintenance assembly 2 does not need to be dismounted and mounted in the process, and convenience in the overhauling and maintaining process is improved.

In one embodiment, the maintenance assembly 2 includes a body 21 and a movable member 22, the body 21 defines a maintenance hole 211, and the movable member 22 is movably connected to the body 21 to open or close the maintenance hole 211.

Referring to fig. 4 and 5, the main body 21 may be a triangular plate-shaped structure, the main body 21 is provided with a maintenance hole 211, and the movable member 22 may be connected to the main body 21 by a hinge or a sliding rail. The slide rail connection can adopt roller type, steel ball type, gear type, common slide rail and other modes. In this embodiment, a common sliding rail manner may be adopted, two guide rails are disposed on the upper and lower sides of the maintenance hole 211 of the body 21, the movable element 22 is mounted on the guide rails along the extension direction of the guide rails, and the maintenance hole 211 can be opened or closed by pushing and pulling the movable element 22. It should be noted that, in actual production, the type of the slide rail structure can be freely selected according to technical requirements, and the present application is not particularly limited to this. In order to further improve the connection stability between the moving member 22 and the body 21, a conventional fastening structure may be disposed on the moving member 22 and a connecting portion may be correspondingly disposed on the body 21, in this embodiment, a thumb screw is disposed on the moving member 22, and a screw hole is disposed on the body 21, and when the moving member 22 moves in place, the thumb screw may be screwed to enable the thumb screw to be in threaded connection with the screw hole.

In this embodiment, a maintenance person can open the maintenance hole 211 on the maintenance component 2 by driving the movable member 22 to move, and maintain the water tray 100 and the position of the water outlet 121 on the water tray 100 through the maintenance hole 211, so that the maintenance convenience of the water tray 100 is improved. Furthermore, in connection with the previous embodiments, the movable member 22 may be provided entirely as a transparent portion to facilitate the manufacture of the maintenance assembly 2 as a whole.

In one embodiment, the first water receiving part 11 forms a slope from high to low from one end close to the high-side connecting part 14 to one end close to the low-side connecting part; the second water receiving portion 13 forms a slope from the end close to the high-side connection portion 14 to the end close to the low-side connection portion.

Referring to fig. 2, the inclination angles of the first water receiving portion 11 and the second water receiving portion 13 relative to the horizontal plane may be selected from the range of 1 ° to 30 °, because the inclination postures of the first water receiving portion 11 and the second water receiving portion 13, the condensed water received by the two portions will naturally flow to the low side connection portion and then flow out from the water outlet 121 at the bottom of the low side connection portion. This scheme can improve drainage efficiency, avoids ponding.

In one embodiment, the water-receiving tray 100 is further provided with a convex edge 15 arranged around the air holes 1, the convex edge 15 protrudes 10-20mm higher than the water-receiving tray 100, and specifically, the protruding height of the convex edge 15 can be 10mm, 12mm, 14mm, 16mm, 18mm or 20mm.

Referring to fig. 3, in order to prevent the condensed water in the water pan 100 from entering the air vent 1, the convex edge 15 disposed around the air vent 1 is disposed on the water pan 100, and the convex edge 15 can prevent the condensed water from splashing to the air vent 1 from the water pan 100, but the convex edge 15 can increase the wind resistance in the direction of the air vent 1 and even generate a wind catching phenomenon, thereby affecting the air volume of the air conditioner. Therefore, the inventor obtains through experiments and analysis that when the convex edge 15 is 10-20mm higher than the water pan 100, the convex edge 15 can not only block condensed water from entering the air vent 1, but also avoid the convex edge 15 from generating excessive resistance to air flow, thereby ensuring the operation stability and the operation efficiency of the air conditioner.

In one embodiment, the water pan 100 comprises a first base 3 and a second base 4, the first base 3 is arranged between the first water receiving part 11 and the first heat exchanger 111, the second base 4 is arranged between the second water receiving part 13 and the second heat exchanger 112, a first water inlet 31 is arranged on one side of the first base 3 away from the second base 4, a first water outlet 32 is arranged on one side of the first base 3 close to the second base 4, and the first water inlet 31 is communicated with the first water outlet 32; one side of the second base 4, which is far away from the first base 3, is provided with a second water inlet 41, one side of the second base 4, which is close to the first base 3, is provided with a second water outlet 42, and the second water inlet 41 is communicated with the second water outlet 42.

Referring to fig. 6 and 7, the first base 3 and the second base 4 are connected between the heat exchange assembly 110 and the water pan 100, so that the connection relationship and the position relationship between the two are more stable. Most of the condensed water flowing from the surface of the first heat exchanger 111 to the water pan 100 gathers at the inner side of the first water receiving part 11 close to the air vent 1 because of the influence of the structural shape of the heat exchange assembly 110 and the gas flow direction factor; most of the condensed water flowing from the surface of the second heat exchanger 112 to the drain pan 100 collects on the inner side of the second drain portion 13 close to the ventilation hole 1. However, a part of the condensed water is still collected at the outer side of the first water receiving portion 11 far from the air vent 1 and the outer side of the second water receiving portion 13 far from the air vent 1, and the part of the condensed water is blocked by the base and the maintenance assembly 2 and cannot flow into the water outlet 121 at the bottom of the low side water receiving portion 12 in time. For this purpose, in the present embodiment, the first base 3 is provided with the first water inlet 31 and the first water outlet 32, and the second base 4 is provided with the second water inlet 41 and the second water outlet 42. Therefore, the condensed water collected on the side of the first water receiving part 11 far away from the air vent 1 can sequentially pass through the first water inlet 31 and the first water outlet 32 and flow to the water outlet 121 at the bottom of the low water receiving part 12 along with the condensed water on the side of the first water receiving part 11 near the air vent 1; similarly, the condensed water collected on the side of the second water receiving portion 13 far from the air vent 1 can sequentially pass through the second water inlet 41 and the second water outlet 42, and flow to the water outlet 121 at the bottom of the low water receiving portion 12 along with the condensed water on the side of the second water receiving portion 13 near the air vent 1. This scheme has further improved water collector 100's drainage efficiency, has avoided ponding.

In one embodiment, the cross-sectional area of the first water outlet 32 is larger than the cross-sectional area of the first water inlet 31, and the cross-sectional area of the second water outlet 42 is larger than the cross-sectional area of the second water inlet 41.

Referring to fig. 7, the cross-sectional area of the first water outlet 32 is the area of the cross-section of the first water outlet 32 perpendicular to the extending direction thereof; the cross-sectional area of the first water inlet 31 is the area of the cross-section of the first water inlet 31 perpendicular to the direction of extension thereof; the cross-sectional area of the second water outlet 42 is the area of the cross section of the second water outlet 42 perpendicular to the extending direction thereof; the cross-sectional area of the second water inlet 41 is the area of a cross-section of the second water inlet 41 perpendicular to its direction of extension. It should be noted that in this embodiment, besides that the condensed water may flow along each water inlet and outlet, the gas may also flow along each water inlet and outlet under the action of the pressure difference. Therefore, gas and liquid enter from the smaller first water inlet 31 and then flow out from the larger first water outlet 32, so that direct disturbance of the gas and the liquid to the condensed water on the water receiving tray 100 can be reduced, and the problem of splashing of the condensed water on the water receiving tray 100 is solved. Similarly, the gas and the liquid enter from the smaller second water inlet 41 and then flow out from the larger second water outlet 42, so that the direct disturbance of the gas and the liquid to the condensed water on the water tray 100 can be reduced.

In one embodiment, the projection range of the first water outlet 32 is staggered with the projection range of the first water inlet 31, and the projection range of the second water outlet 42 is staggered with the projection range of the second water inlet 41.

Referring to fig. 7, the first water inlet 31 and the first water outlet 32 are arranged in a staggered manner, so that the flow resistance of air and liquid in a channel communicating the first water inlet 31 and the first water outlet 32 is increased, and thus, the condensed water on the water-receiving tray 100 is prevented from being disturbed by direct flushing of gas or liquid; similarly, the second water inlet 41 and the second water outlet 42 are arranged in a staggered manner, so that the flowing resistance of air and liquid in a channel communicating the second water inlet 41 and the second water outlet 42 is increased, and the condensed water on the water-receiving tray 100 is prevented from being disturbed by direct flushing of gas or liquid.

When the water pan 100 is used, bubbles always appear at the water outlet 121, because the upper end of the water outlet 121 is communicated with the space between the water pan 100 and the heat exchange assembly 110, the space is a low-pressure space under the condition of air suction of the air holes 1, and the lower end of the water outlet 121 is communicated with an external normal-pressure space, therefore, the air pressure at the upper end of the water outlet 121 is lower than that at the lower end of the water outlet 121, the water outlet 121 inevitably sucks certain air from bottom to top in the drainage process, bubbles can be generated after the air and the condensed water are mixed, a certain amount of condensed water can be sputtered when the bubbles break, and the condensed water can be sputtered to the air holes 1, so that the normal operation of the air conditioning equipment is influenced.

In one embodiment, the maintenance assembly 2 further comprises a drainage upper cover plate 23, the drainage upper cover plate 23 is disposed on one side of the maintenance assembly 2 close to the vent 1, and the drainage upper cover plate 23 is located above the drainage opening 121.

Referring to fig. 4 and 5, the upper drainage cover 23 may be fixed to the maintenance assembly 2 by a conventional fastening structure, and in combination with the above-mentioned embodiment, the upper drainage cover 23 may be fixed to the movable member 22, so that when the movable member 22 is opened, the upper drainage cover 23 moves along with the movable member 22 and leaves the position right above the drainage opening 121, thereby preventing the upper drainage cover 23 from affecting the maintenance of the drainage opening 121. Further, since the drainage upper cover plate 23 is shielded above the drainage opening 121 in the operating state of the air conditioning equipment, the drainage upper cover plate 23 may be made of a transparent material to avoid affecting the maintenance of the drainage opening 121. The main structure of the upper drainage cover 23 may be a flat plate structure, which may be perpendicular to the axis of the drainage port 121, and the edge of the upper drainage cover 23 may further be provided with a surrounding portion to block splashed droplets generated by bubbling of condensed water at the drainage port 121 from more angles. In conclusion, the drainage upper cover plate 23 can prevent the problem of splashing of the condensed water caused by bubbling of the condensed water at the water outlet 121, so that the condensed water is prevented from being blown out of the water pan 100, and the stable operation of the water pan 100 and the air conditioning equipment is ensured.
