Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to a heat exchanger bracket, an indoor air conditioning unit, and an air conditioner. Background Technology

[0002] When a wall-mounted air conditioner is cooling, condensation will continuously form on the heat exchanger fins and the outer surface of the copper pipes. Please refer to [link / reference]. Figure 1 A water collection pan 10 is provided on the lower side of the heat exchanger. Under normal circumstances, the condensate formed on the heat exchanger will flow into the water collection pan 10 and then flow to the outside through the drain port 20 on the water collection pan 10.

[0003] The heat exchanger bracket 30 on the left side of the wall-mounted air conditioner's heat exchanger is a crucial component in the condensate recovery path. During actual use, the heat exchanger bracket 30 directly contacts the fins and copper tubing on the evaporator body. During cooling, a large amount of condensate passes through this bracket 30 and is guided into the condensate pan 10. As the condensate flows along the surface of the heat exchanger bracket 30, due to the inclined surface, its downward flow speed increases under acceleration, eventually causing it to fly out from the right side and fail to be successfully recovered.

[0004] If the condensate on the heat exchanger bracket 30 fails to flow into the condensate pan 10, water will accumulate inside the air conditioner's front frame and base, causing water to seep out from the inside of the air conditioner and drip onto the outside, damaging furniture and other items, or even causing short circuits in electrical products, posing safety hazards such as fire.

[0005] Therefore, it is necessary to propose a new heat exchanger bracket, air conditioning indoor unit, and air conditioner. Utility Model Content

Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and objectives achieved by this utility model, should still fall within the scope of the technical content disclosed in this utility model.

[0035] As described in the background section, in existing heat exchanger supports, when condensate flows along its surface, the inclined plane causes the condensate to accelerate from top to bottom, eventually causing it to fly out from the right side and fail to be successfully collected. Therefore, this invention proposes a heat exchanger support to avoid the problem of condensate not being successfully collected.

[0036] Please see Figures 2-4 , Figure 2 This is a three-dimensional structural diagram of a heat exchanger support provided in an embodiment of the present invention. Figure 3 This is a front view schematic diagram of a heat exchanger bracket provided in an embodiment of the present invention. Figure 4 This is a partial structural diagram of a heat exchanger bracket provided in one embodiment of the present invention. The heat exchanger bracket provided by the present invention is applied to an indoor air conditioning unit. The heat exchanger bracket matches the end of the heat exchanger in the indoor air conditioning unit to support and fix one end of the heat exchanger. The heat exchanger bracket includes:

[0037] The airflow shielding wall 100 and the water-blocking diversion section 200 connected to the airflow shielding wall 100 are used to separate the internal airflow of the heat exchanger from the external space. The upper edge of the water-blocking diversion section 200 has a slope, and the side of the water-blocking diversion section 200 facing away from the heat exchanger is provided with a plurality of water-blocking ribs 210. The water-blocking ribs 210 extend downward from the upper edge so that the condensate on the upper edge is guided to flow downward along the water-blocking ribs 210.

[0038] The heat exchanger bracket provided by this utility model has a water-blocking and diversion section 200, on which a plurality of water-blocking ribs 210 are provided. The water-blocking ribs 210 extend downward from the upper edge of the water-blocking and diversion section 200, guiding the condensate to flow downward along the water-blocking ribs 210. This avoids the problem that the condensate will increase its flow speed from top to bottom under the action of acceleration and eventually fly out from the right side, failing to be successfully recovered.

[0039] In some embodiments, a plurality of water-blocking ribs 210 are spaced apart along the upper edge to form a height difference. Since the upper edge 200 has a slope, the plurality of water-blocking ribs 210 form a height difference, creating obstructions at different heights as condensate flows from top to bottom, reducing the flow velocity of the condensate and preventing it from splashing out.

[0040] In some embodiments, the heat exchanger support further includes a plurality of guide ribs 220 disposed on the water-blocking flow portion 200, some of the guide ribs 220 being connected to the lower end of the water-blocking rib 210 and extending in a direction substantially parallel to the upper edge. In this embodiment, some condensate is blocked by the first side of the water-blocking rib 210 and flows downward along the first side of the water-blocking rib 210, while some condensate flows along the second side of the water-blocking rib 210 and is guided down by the guide ribs 220.

[0041] In some embodiments, the water-blocking rib 210 includes a first water-blocking rib 211, a second water-blocking rib 212, and a third water-blocking rib 213 arranged sequentially from high to low; the lower end of the first water-blocking rib 211 is connected to a first drainage rib 221, and the lower end of the second water-blocking rib 212 is connected to a second drainage rib 222; wherein the lower end of the first drainage rib 221 is not higher than the upper end of the second water-blocking rib 212, and the lower end of the second drainage rib 222 is not higher than the upper end of the third water-blocking rib 213.

[0042] In the above embodiments, the lower end of the first drainage rib 221 is not higher than the upper end of the second water-blocking rib 212, so as to prevent condensed water from passing over the second water-blocking rib 212 during the process of sliding down the first drainage rib 221; the lower end of the second drainage rib 222 is not higher than the upper end of the third water-blocking rib 213, so as to prevent condensed water from passing over the third water-blocking rib 213 during the process of sliding down the second drainage rib 222.

[0043] In some embodiments, a first diversion groove 231 is formed between the lower end of the first guide rib 221 and the second water-blocking rib 212; a second diversion groove 232 is formed between the lower end of the second guide rib 222 and the third water-blocking rib 213. By setting the diversion grooves, the condensate is dispersed into multiple paths to flow downwards, turning large water droplets into multiple small water droplets as they slide down, preventing splashing out when falling into the water collection tray.

[0044] In some embodiments, the heat exchanger support further includes a third guide rib 223, the upper end of which extends from the highest point of the upper edge to a lower end below the upper end of the first water-blocking rib 211, and the lower end of the third guide rib 223 forms a third diversion groove 233 between itself and the first water-blocking rib 211. By providing the third guide rib 223 and the third diversion groove 233, the condensate above the water-blocking diversion section 200 is guided to flow downwards.

[0045] In some embodiments, the water-blocking and diversion section 200 is further provided with a plurality of waist-shaped holes 240 for accommodating the hairpin U-shaped bend on the heat exchanger, and the edge of the waist-shaped hole 240 is provided with a fixing hook 241 for fixing the hairpin U-shaped bend.

[0046] In some embodiments, the heat exchanger bracket further includes a fixing plate (not shown) connected to the air duct shielding wall, the fixing plate having at least two base fixing holes for connecting the heat exchanger bracket to the base screws.

[0047] This embodiment also provides an indoor air conditioning unit, including the heat exchanger bracket provided in this embodiment.
