Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and particularly relates to an evaporator support structure and an air conditioner. Background Art

[0002] In the air-conditioning industry, an evaporator usually includes angled first fins and second fins. The lower ends of the first fins and the second fins are connected, and the upper ends of the first fins and the second fins are connected to a base through a mounting bracket, so that the lower ends of the first fins and the second fins are spaced apart from the base. However, since the first fins and the second fins are arranged in a suspended manner, when an external force acts on the evaporator, such as when an external force acts at the intersection of the first fins and the second fins, the evaporator is liable to shake or even deform in the front-back direction of the indoor unit of the air conditioner, resulting in poor mounting reliability of the evaporator on the base.

Detailed Description of the Embodiments

[0026] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0027] The following will be combined with Figures 1 - 4 to describe the evaporator support structure according to an embodiment of the present invention.

[0028] The evaporator support structure according to an embodiment of the present utility model includes a base 1 for installing an evaporator 2. The evaporator 2 includes a mounting bracket 20 and an evaporator body. The evaporator body includes a first heat exchange portion 21 and a second heat exchange portion 22 arranged in sequence in a first direction. The first heat exchange portion 21 is mounted on the mounting bracket 20. The first end of the first heat exchange portion 21 in the first direction is connected to the first end of the second heat exchange portion 22 in the first direction and forms an angle therebetween. A support portion 10 is provided at the first end of the base 1 in the first direction for abutting against the side of the first heat exchange portion 21 away from the second heat exchange portion 22 and / or the side of the mounting bracket 20 opposite to the first direction.

[0029] According to the evaporator support structure of the embodiment of the present utility model, the support portion 10 is provided at the first end of the base 1 in the first direction. After the evaporator 2 is installed on the base 1, the side of the first heat exchange portion 21 of the evaporator 2 away from the second heat exchange portion 22 abuts against the support portion 10, and / or the side of the mounting bracket 20 of the evaporator 2 opposite to the first direction abuts against the support portion 10. Thus, the support portion 10 realizes the support of the evaporator 2 in the first direction. When the evaporator 2 is subjected to an external force, it is less likely to shake and deform, and the installation reliability of the evaporator 2 on the base 1 is high.

[0030] It should be noted that the first direction is the front-rear direction of the installed room air conditioner, and the second direction is the left-right direction of the installed room air conditioner. That is, the first heat exchange portion 21 is located behind the second heat exchange portion 22, and the lower end of the first heat exchange portion 21 is connected to the lower end of the second heat exchange portion 22. The first heat exchange portion 21 and the second heat exchange portion 22 are fins through which heat exchange copper tubes are passed, and the first heat exchange portion 21 and the second heat exchange portion 22 are installed on the base 1 through the mounting bracket 20.

[0031] In some embodiments, the second end of the first heat exchange portion 21 in the first direction is connected to the base 1 through the mounting bracket 20, and the support portion 10 is provided adjacent to the second end of the first heat exchange portion 21 in the first direction.

[0032] The second end in the first direction is the rear end of the first heat exchange portion 21 and also the upper end of the first heat exchange portion 21. The distance between the rear side of the first heat exchange portion 21 and the base 1 gradually decreases from bottom to top. By providing the support portion 10 adjacent to the upper end of the first heat exchange portion 21, while ensuring that the support portion 10 can support the evaporator 2 in the first direction, the size of the support portion 10 in the front-rear direction is smaller, effectively reducing the manufacturing cost of the base 1.

[0033] Specifically, the support portion 10 abuts against the rear side of the mounting bracket 20, which avoids direct contact between the first heat exchange portion 21 and the support portion 10, resulting in condensation water due to a lower temperature at the position of the support portion 10.

[0034] In some embodiments, such asFigure 1 and Figure 4 As shown in Figure 4 , the mounting bracket 20 includes a first bracket 23 and a second bracket 24. The first bracket 23 and the second bracket 24 are respectively connected to the first end and the second end of the first heat exchange part 21 in the second direction. The second direction is perpendicular to the first direction. The first bracket 23 is snap-connected to the base 1, and the second bracket 24 is connected to the base 1 through a fastener. The support part 10 includes a first support part 11. The first support part 11 is arranged at the first end of the base 1 in the second direction, and the first support part 11 abuts against the side surface of the first bracket 23 opposite to the first direction.

[0035] That is, the first bracket 23 is snap-connected to the left end of the base 1, and the second bracket 24 is connected to the right end of the base 1 through a fastener. At this time, the connection strength between the left end of the evaporator 2 and the base 1 is lower than the connection strength between the right end of the evaporator 2 and the base 1. By arranging the first support part 11 to abut against the rear side surface of the first bracket 23, the support for the left end of the evaporator 2 in the front-rear direction is realized, which can better prevent the evaporator 2 from shaking and deforming when subjected to external forces, and the installation reliability of the evaporator 2 on the base 1 is higher.

[0036] Specifically, when the rear side surface of the first bracket 23 abuts against the first support part 11, the upper end surface of the first bracket 23 can also abut against the base 1. Combining with the snap connection between the first bracket 23 and the base 1, the installation reliability of the first bracket 23 on the base 1 is effectively guaranteed. At the same time, while the second bracket 24 is connected to the base 1 through a fastener, it is also snap-connected to the base 1 to realize the pre-positioning of the second bracket 24 on the base 1, which facilitates the connection between the second bracket 24 and the fastener by the fastener.

[0037] In some embodiments, as Figure 1 and Figure 2 shown, the first support part 11 extends in the second direction. The outer contour of the positive projection of the first support part 11 in the second direction is triangular. The first support part 11 is formed with a first support surface 111 parallel to the side surface of the first heat exchange part 21 away from the second heat exchange part 22. The first bracket 23 includes a folded edge 231 located on the side of the first heat exchange part 21 away from the second heat exchange part 22, and the folded edge 231 abuts against the first support surface 111.

[0038] At this time, the first support portion 11 supports the evaporator 2 in the obliquely forward and upward direction through the first support surface 111, so that the support effect on the evaporator 2 is better, and external impacts can be better offset, and the fixing reliability of the evaporator 2 on the base 1 is higher. In addition, the design of the flanging 231 on the first bracket 23 makes the distance between the first support portion 11 and the first heat exchange portion 21 larger, and the heat transfer efficiency between the two is lower, and it is more difficult for the first support portion 11 to generate condensed water due to too low temperature. At the same time, the first support portion 11 with a triangular cross-sectional outer contour has higher structural stability, and it is more difficult for the first support portion 11 to bend downward relative to the base 1 and deform.

[0039] Specifically, the first bracket 23 is a sheet metal part, and the flanging 231 protrudes from the rear side of the rear side surface of the first heat exchange portion 21.

[0040] In some embodiments, as Figure 2 shown, the evaporator support structure further includes a motor 3. The motor 3 is installed on the base 1. The motor 3 includes a motor base 31. The motor base 31 is adjacent to the first end of the base 1 in the second direction, and the motor base 31 is clamped to the first bracket 23.

[0041] That is, the base 1 is clamped to the first bracket 23 through the motor base 31 of the motor 3, so that the structure of the base 1 is simple, and the manufacturing cost of the base 1 is further reduced.

[0042] Specifically, the motor 3 is used to drive the cross-flow fan wheel to rotate. The motor base 31 of the motor 3 is provided with a connecting flange, and the connecting flange is clamped to the upper end of the first bracket 23.

[0043] In some embodiments, as Figure 2 shown, the motor base 31 is provided with a protrusion 311 extending in the second direction. The first bracket 23 is connected to the second heat exchange portion 22. A clamping hole 232 is provided in a portion of the first bracket 23 located between the first heat exchange portion 21 and the second heat exchange portion 22, and the protrusion 311 is clamped in the clamping hole 232.

[0044] That is, the motor base 31 fixes the first bracket 23 in the up and down direction through the protrusion 311, ensuring that the first bracket 23 is reliably suspended and fixed on the base 1.

[0045] Specifically, the outer surface of the protrusion 311 is preferably a spherical surface or a conical surface. When the evaporator 2 moves toward the base 1 from front to back, it is convenient for the first bracket 23 to slide relative to the protrusion 311, so that when the evaporator 2 moves into place, the protrusion 311 is clamped in the clamping hole 232. In addition, there are two protrusions 311, and the cooperation between the two protrusions 311 and the two clamping holes 232 further improves the installation reliability of the first bracket 23 on the base 1.

[0046] In some embodiments, as Figure 1As shown, the support part 10 further includes a second support part 12. The second support part 12 is provided at the second end of the base 1 in the second direction, and the second support part 12 abuts against the side surface of the second bracket 24 opposite to the first direction.

[0047] That is, the second support part 12 abuts against the rear side surface of the second bracket 24 to support the right end of the evaporator 2 in the front-rear direction. Combining with the first support part 11, the support stability of the evaporator 2 in the front-rear direction is better, and the installation reliability of the evaporator 2 on the base 1 is higher.

[0048] Specifically, the second support part 12 is integrally formed with the base 1, and the outer surface of the second support part 12 is in close contact with the rear side surface of the second bracket 24.

[0049] In some embodiments, as Figure 1 shown, the second support part 12 includes an angled second support surface 121 and a third support surface 122, and the second bracket 24 abuts against each of the second support surface 121 and the third support surface 122.

[0050] The angled second support surface 121 and third support surface 122 abut against the second bracket 24, making the limiting reliability of the second support part 12 for the second bracket 24 in the front-rear direction and the up-down direction higher. At the same time, it is also more convenient for the second bracket 24 to be positioned on the base 1, and thus the efficiency of connecting the second bracket 24 and the base 1 with fasteners is higher.

[0051] Specifically, the second support surface 121 is located above the third support surface 122, and the second support surface 121 is in close contact with the rear side surface of the second bracket 24.

[0052] In some embodiments, as Figure 1 shown, a threaded hole 123 is provided on the third support surface 122, and a mounting hole corresponding to the threaded hole 123 is provided on the second bracket 24. The fastener is a threaded part, and the threaded part passes through the mounting hole and is in threaded cooperation with the threaded hole 123.

[0053] After the evaporator 2 is snap-connected to the base 1 to achieve pre-positioning, the threaded part passes through the mounting hole and is in threaded cooperation with the threaded hole 123, that is, the connection between the second bracket 24 of the evaporator 2 and the base 1 is realized, and the disassembly and assembly of the evaporator 2 on the base 1 are convenient.

[0054] Specifically, the threaded part is a bolt and the number is one, and the mounting hole is adjacent to the lower end of the second bracket 24.
