Description

Technical Field

[0001] The invention relates to the field of air conditioning, in particular to an evaporator angle frame, an evaporator having the same and an air conditioning indoor unit. Background Art

[0002] In the traditional air conditioner industry, the evaporator is generally placed in an inverted "V" shape, and the air duct is designed for upper air intake and lower air outlet. Therefore, the angle frame that matches the evaporator of the traditional air conditioner is also an inverted "V" structure. During the operation of the evaporator, condensed water will be generated on the surface of the evaporator copper tube and the angle frame. Since the angle frame is an inverted "V" structure, under the action of gravity, the condensed water can flow down from top to bottom and be collected, such as the patent number CN201820121218.6, a heat exchanger having the same, and an air conditioner indoor unit. With the development of technology, evaporators with a positive "V" shape have appeared in the air-conditioning industry. The air duct is designed with air inlet at the bottom and air outlet at the top. It is obviously not feasible to directly flip the conventional inverted "V" angle frame 180° to match the evaporator placed in the positive "V" shape, or to apply the drainage structure of the conventional inverted "V" angle frame to the positive "V" angle frame. The following problems will arise: 1. Condensate cannot be collected because the position for collecting condensate in the traditional inverted "V" angle frame is generally located at both ends of the "V"; 2. Even if the position for collecting condensate is changed to the bottom, in the case of a positive "V" shape, the condensate on the outside of the angle frame will drip directly due to gravity instead of flowing along the outside of the angle frame.

[0003] Therefore, the condensed water generated on the evaporator and the angle frame cannot be guided to flow to the water receiving tray by the traditional drainage structure. It is necessary to propose a new angle frame drainage structure and flow path. Summary of the invention

[0004] In order to solve the technical problem that the drainage structure of the conventional angle frame does not meet the drainage requirements of a positive "V" type evaporator, the present invention provides an evaporator angle frame, comprising a main body and an upper drainage structure (1), a left drainage structure (2) and a right drainage structure (3) which are integrally arranged with the main body, wherein the lower end of the upper drainage structure (1) is connected to the upper end of the left drainage structure (2) or the right drainage structure (3), and the lower end of the left drainage structure (2) is connected to the lower end of the right drainage structure (3), that is, the left drainage structure (2) and the right drainage structure (3) are in a positive "V" shape, and a water receiving tray (4) is arranged at the connection between the lower end of the left drainage structure (2) and the lower end of the right drainage structure (3) to receive condensed water generated on the angle frame, so that the drainage structure of the angle frame is mainly divided into three parts, namely, the upper part, the left part and the right part, the condensed water in the upper part flows to the upper part of the left part or the right part, and the condensed water in the left part and the right part finally gathers at the bottom and is collected by the water receiving tray (4).

[0005] The lower end of the upper drainage structure (1) is connected to the upper end of the left drainage structure (2), and the upper drainage structure (1) comprises a plurality of first drainage parts (104) arranged from top to bottom, wherein the first drainage part (104) is provided with a first inner cavity (102) connected to the evaporator copper tube (5), and the top and bottom of the first inner cavity (102) of the first drainage part (104) are both provided with first guide holes (105), and the first inner cavities (102) of adjacent first drainage parts (104) are connected through the first guide holes (105), and the bottom of the first inner cavity (102) adjacent to the left drainage structure (2) is provided with an upper drainage drainage hole (103) to drain all condensed water generated in the upper drainage structure (1) to the outside of the left drainage structure (2), and the outer side surface of the first drainage part (104) of the upper drainage structure (1) is a first drainage surface (101);

[0006] The condensed water generated in the first inner cavity (102) flows to the first guide hole (105) at the bottom under the action of gravity, and then enters the first inner cavity (102) adjacent below, and finally all the condensed water generated in the first inner cavity (102) converges inside the last first inner cavity (102), and flows out through the upper drainage hole (103) at the bottom of the last first inner cavity (102) to the top of the left drainage structure (2);

[0007] Condensed water generated outside the first drainage portion (104) is drained to the top of the left drainage structure (2) via the first drainage surface (101); since the inclination angle of the upper drainage structure (1) relative to the vertical direction is small, the condensed water outside the upper drainage structure (1) will not drip directly.

[0008] The left drainage structure (2) comprises a plurality of second drainage portions (205) arranged from top to bottom. A first water diversion retaining rib (202) and a second water diversion retaining rib (206) are arranged on the outer side of the left drainage structure (2). The first water diversion retaining rib (202) is connected to the outer side of the second drainage portion (205). The second drainage portion (205) at the connection point is provided with a left drainage first drainage hole (207). Condensate water diverted by the first water diversion retaining rib (202) flows into the second drainage portion (205) through the left drainage first drainage hole (207). The second water diversion retaining rib (206) is located between two adjacent second drainage portions (205) to divert the condensate water located at the second drainage portion (205). Condensed water generated by the upper second drainage portion (205) is drained to the top of the lower second drainage portion (205); a second inner cavity (203) connected to the evaporator copper tube (5) is provided inside the second drainage portion (205); a left drainage second drainage hole (204) is provided at the bottom of the second inner cavity (203); the left drainage first drainage hole (207) connects the second inner cavity (203) with the external first water diversion retaining rib; the inner side of the outer side of the second drainage portion (205) is a second drainage surface (201); a middle protrusion of the top (208) (208) of the second drainage portion (205) forms inclined surfaces on both sides of the top.

[0009] The condensed water generated in the second inner cavity (203) flows to the left drainage second drainage hole (204) at the bottom under the action of gravity, and then the condensed water enters the upper outer side of the adjacent second drainage portion (205) below. At this time, since the condensed water flows to the inclined surface of the top (208) (208) of the second drainage portion (205), the condensed water may be diverted: a part of the condensed water flows to the outer side of the second drainage portion (205), is blocked by the first water diversion retaining rib (202) and is diverted to the left drainage first drainage hole (207) of the second drainage portion (205) adjacent to the first water diversion retaining rib (202), and enters the second inner cavity (203) of the second drainage portion (205); the other part of the condensed water flows along the second drainage surface (201). At the same time, condensed water generated outside the second drainage portion (205) flows along the second drainage surface (201) or is drained by the first water diversion retaining rib (202) or the second water diversion retaining rib (206), and finally all condensed water generated in the second inner cavity (203) converges into the last second inner cavity (203) and flows out into the water receiving tray (4) through the left drainage second drainage hole (204) at the bottom of the last second inner cavity (203), and condensed water outside the second drainage portion (205) flows along the second drainage surface (201) into the water receiving tray (4).

[0010] The right drainage structure (3) comprises a plurality of third drainage parts (305) arranged from top to bottom, wherein a third inner cavity (302) connected to the evaporator copper tube (5) is arranged inside the third drainage part (305), and a right drainage hole (303) is arranged at the bottom of the third inner cavity (302) of the third drainage part (305), wherein the right drainage hole (303) connects the third inner cavity (302) with the outside, and a bottom shell is also arranged at the connection between the evaporator and the angle frame, and condensed water generated in the third inner cavity (302) of the right drainage structure (2) of the angle frame flows from the third inner cavity (302) to the outside of the angle frame, and flows along the edge (307) of the bottom shell on the side where the angle frame is connected to the evaporator, until it is received by the water receiving tray (4) below;

[0011] A third drainage surface (304) is arranged on the outer side of the right drainage structure (3), and the third drainage surface (304) comprises a plurality of outer side surfaces (306) of the third drainage portion (305) and a plurality of inwardly concave stepped protrusions (301) arranged on the outer side surfaces (306) of the third drainage portion (305). The top of the right drainage structure (3) is an inclined surface, and the bottom end of the inclined surface of the third drainage portion (305) is connected to the third drainage surface (304).

[0012] Preferably, the top of the third inner cavity (302) of the plurality of third drainage portions (305) located in the middle of the right drainage structure (3) is provided with a second flow-guiding hole, and the second flow-guiding hole connects the third inner cavity (302) with the outside;

[0013] The condensed water generated in the third inner cavity (302) flows to the right drainage hole (303) at the bottom under the action of gravity, and then the condensed water enters the third inner cavity (302) adjacent below through the second diversion hole, and finally all the condensed water generated in the third inner cavity (302) gathers inside the last third inner cavity (302) and flows out to the water receiving tray (4) through the right drainage hole (303) at the bottom of the last third inner cavity (302);

[0014] Condensed water generated outside the third drainage portion (305) flows along the third drainage surface (304) under the action of gravity because it is on an inclined surface;

[0015] The third drainage surface (304) is provided with a plurality of inwardly concave stepped protrusions (301). When condensed water is generated on the outside of the third drainage portion (305) due to the effects of cold radiation and cold transfer, the condensed water can flow downstream along the third drainage surface (304), but the third drainage surface (304) cannot have outwardly protruding sharp points to cause water accumulation. When a protrusion must be made due to mold release or parting line reasons, an inwardly concave stepped protrusion (301) can be selected to effectively prevent water droplet accumulation, so that the condensed water on the outside of the third drainage portion (305) eventually flows along the third drainage surface (304) into the water receiving tray (4).

[0016] The upper drainage structure (1), the left drainage structure (2) and the right drainage structure (3) are provided with a clamping portion (6) for clamping the evaporator copper tube (5).

[0017] Furthermore, the first inner cavity (102) is provided with a first clamping portion, the second inner cavity (203) is provided with a second clamping portion, and the third inner cavity (302) is provided with a third clamping portion, and the angle frame and the evaporator are tightly connected via the clamping portion (6).

[0018] The evaporator comprises an evaporator body. The evaporator is placed in a positive "V" shape. The evaporator air duct has a lower air inlet and an upper air outlet. The above-mentioned evaporator angle bracket is installed to fix and limit the evaporator.

[0019] An air conditioner indoor unit comprises the above-mentioned evaporator, the upper drainage structure (1), the left drainage structure (2) and the clamping part (6) of the right drainage structure (3) of the angle frame clamp and fix the evaporator copper tube (5), and the upper drainage structure (1), the left drainage structure (2) and the right drainage structure (3) guide the condensed water generated at the connection between the angle frame and the evaporator to flow to the water receiving tray (4) located at the bottom.

[0020] Beneficial Effects

[0021] The drainage structure of the present invention is mainly divided into three parts: an upper drainage structure (1), a left drainage structure (2) and a right drainage structure (3). Condensed water from the upper drainage structure (1) flows to the upper part of the left drainage structure (2) or the right drainage structure (3). Condensed water from the left drainage structure (2) and the right drainage structure (3) is finally gathered at the bottom and collected by a water receiving pan (4). By providing a water diversion retaining rib on the left drainage structure (2) and providing an inwardly concave stepped protrusion (301) on the right drainage structure (3), condensed water on both sides of the positive "V"-shaped angle frame can also be smoothly drained to the water receiving pan (4) for collection.

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-14 The drainage method of the present invention is further described with reference to the accompanying drawings and embodiments.

[0038] Example 1

[0039] An evaporator angle frame comprises a main body and an upper drainage structure (1), a left drainage structure (2) and a right drainage structure (3) which are integrally arranged with the main body, wherein the lower end of the upper drainage structure (1) is connected to the upper end of the left drainage structure (2), and the lower end of the left drainage structure (2) is connected to the lower end of the right drainage structure (3), that is, the left drainage structure (2) and the right drainage structure (3) are in a positive "V" shape, and a water receiving tray (4) is arranged at the connection point to receive condensed water generated on the angle frame.

[0040] The drainage channels of the angle frame include six.

[0041] The first drainage channel is the direction of condensed water flow in the first inner cavity (102) of the first drainage portion (104) of the upper drainage structure (1). The condensed water generated in the first inner cavity (102) flows to the first drainage pores (105) at the bottom under the action of gravity, and then enters the first inner cavity (102) adjacent below. Finally, all the condensed water generated in the first inner cavity (102) converges into the inside of the last first inner cavity (102) and flows out through the upper drainage hole (103) at the bottom of the last first inner cavity (102) to the top of the left drainage structure (2).

[0042] The second drainage channel is the direction of flow of condensed water outside the first drainage portion (104) of the upper drainage structure (1). Condensed water generated outside the first drainage portion (104) is drained to the top of the left drainage structure (2) via the first drainage surface (101). Since the upper drainage structure (1) has a small inclination angle, the condensed water outside the upper drainage structure (1) will not drip directly.

[0043] The third drainage channel is the direction of condensed water flow guided by the water diversion retaining ribs of the second drainage portion (205) of the left drainage structure (2), wherein the water diversion retaining ribs include a first water diversion retaining rib (202) located outside the second drainage portion (205) and a second water diversion retaining rib (206) located between the two second drainage portions (205). Figure 5 , Fig.10 and Fig.11 As shown,

[0044] The condensed water drained from the first drainage surface (101) is blocked by the water diversion retaining rib and is drained to the second inner cavity (203) through the left drainage first drainage hole (207) on the outside of the second inner cavity (203). The condensed water generated in the second inner cavity (203) flows to the left drainage second drainage hole (204) at the bottom under the action of gravity, and then the condensed water enters the upper part of the outer side of the adjacent second drainage portion (205) below. At this time, since the condensed water flows to the inclined surface (208) of the top of the second drainage portion (205), the condensed water may be split: a part of the condensed water flows to the outside of the second drainage portion (205), is blocked by the first water diversion retaining rib (202) and is drained to the left drainage drainage hole of the second drainage portion (205) adjacent to the first water diversion retaining rib (202), and enters the second inner cavity (203) of the second drainage portion (205); the other part of the condensed water flows along the second drainage surface (201);

[0045] In addition, condensed water generated outside the second drainage portion (205) can also flow along the outside of the second drainage portion (205) until it is blocked and drained by the second water diversion retaining rib (206), and the condensed water flows to the top of the second drainage portion (205) located below the second water diversion retaining rib (206), and then the condensed water is drained by the first water diversion retaining rib (202);

[0046] Therefore, the condensed water blocked by the water diversion retaining rib and diverted to the second inner cavity (203) is gathered again to the left drainage second drainage hole (204) at the bottom of the second inner cavity (203) and flows out, and the above process is repeated until the condensed water is gathered to the last second inner cavity (203) and enters the water receiving tray (4) through the left drainage second drainage hole (204) at the bottom of the last second inner cavity (203).

[0047] The fourth drainage channel is the direction of flow of condensed water drained via the second drainage surface (201) of the second drainage portion (205) of the left drainage structure (2), flowing downward along the second drainage surface (201) and finally being received by the water receiving tray (4).

[0048] The fifth drainage channel is the direction of condensed water flow in the third inner cavity (302) of the third drainage portion (305) of the right drainage structure (3). Condensed water generated in the third inner cavity (302) of the right drainage structure (2) of the angle frame flows from the third inner cavity (302) to the right drainage hole (303) at the bottom under the action of gravity, and then flows to the outside of the angle frame, and flows along the bottom shell edge (307) on the side where the angle frame is connected to the evaporator until it is received by the water receiving tray (4) below. Fig.14 As shown;

[0049] Preferably, a second guide hole is provided at the top of the third chamber (302), and condensed water generated in the third inner chamber (302) enters the adjacent third inner chamber (302) below through the second guide hole, and finally all condensed water generated in the third inner chamber (302) gathers inside the last third inner chamber (302) and flows out into the water receiving tray (4) through the right drainage hole (303) at the bottom of the last third inner chamber (302).

[0050] The sixth drainage channel is the direction of condensed water flow of the third drainage surface (304) of the right drainage structure (3), and the outer side of the right drainage structure (3) is unified as the third drainage surface (304), and the third drainage surface (304) includes a plurality of outer side surfaces (306) of the third drainage portion (305) and a plurality of inwardly concave stepped protrusions (301) arranged on the outer side surfaces (306) of the third drainage portion (305). Figure 6 and Figure 7 As shown, the third drainage surface (304) is provided with a plurality of inwardly concave stepped protrusions (301). When condensed water is generated on the outside of the third drainage portion (305) due to the effects of cold radiation and cold transfer, the condensed water can flow downstream along the third drainage surface (304), but the third drainage surface (304) cannot have outwardly protruding sharp points to cause water accumulation. When a protrusion must be made due to mold release or parting line reasons, an inwardly concave stepped protrusion (301) can be selected to effectively prevent water droplet accumulation, so that the condensed water on the outside of the third drainage portion (305) eventually flows along the third drainage surface (304) to the water receiving tray (4).

[0051] The water diversion retaining rib and the plurality of left drainage holes are provided on the left drainage structure (2) because the left drainage structure (2) has a large inclination angle relative to the vertical direction. If the water diversion retaining rib is not provided, the condensed water formed on the outside will drip directly and will be difficult to be collected by the water receiving tray (4).

[0052] The water diversion retaining rib is combined with the left drainage structure (2) to actually drain the condensed water blocked by the water diversion retaining rib into the second inner cavity (203), so that the condensed water can be smoothly drained into the water receiving tray (4).

[0053] The reason why the right drainage structure (3) is provided with an inwardly concave stepped protrusion (301) is that the right drainage structure (3) is in an inclined state and condensed water formed on the outside may still drip directly, so the inwardly concave stepped protrusion (301) plays a role of drainage. At the same time, the bottom shell edge (307) cooperates with the right drainage structure (3) so that the condensed water generated in the third inner cavity (302) is discharged to the outside of the right drainage structure (3) and flows downward along the bottom shell edge (307), so that condensed water will not accumulate in the right drainage structure (3).

[0054] From the above description, it can be seen that the drainage structure of the angle frame is mainly divided into three parts: the upper part, the left part and the right part. The condensed water in the upper part flows to the upper part of the left or right part, and the condensed water in the left and right parts finally gathers at the bottom and is collected by the water receiving tray (4).

[0055] The first inner cavity (102), the second inner cavity (203) and the third inner cavity (302) are all provided with a clamping portion (6) for clamping the evaporator copper tube (5), and the angle frame and the evaporator are tightly connected via the clamping portion (6).

[0056] Example 2

[0057] When the lower end of the upper drainage structure (1) is connected to the upper end of the right drainage structure (3) (this connection method is not shown in the attached drawings), the condensed water in the first drainage channel and the second drainage channel eventually flows to the top of the third drainage portion (305) of the right drainage structure (3).

[0058] Condensed water generated by the first drainage channel and the second drainage channel is finally collected by the water receiving tray (4) along the third drainage surface (304) of the right drainage structure (3).

[0059] The rest of the drainage channels are the same as those in Example 1.

[0060] The upper drainage hole (103), the left drainage first drainage hole (207), the left drainage second drainage hole (204) and the right drainage hole (303) all function to drain condensed water generated in the inner cavity where the drainage structure is connected to the evaporator copper tube (5) to the outside of the angle frame, so that the condensed water will not accumulate under the evaporator copper tube (5), thereby avoiding blockage and dirt.

[0061] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
