Description

air conditioner

Technical field

The invention relates to an air conditioner, in particular to an air conditioner with an improved fixing support structure for fixing a heat exchanger to a casing.

Background technique

An air conditioner refers to a device that uses the heat transfer generated during the evaporation and condensation of a refrigerant to adjust the temperature or humidity of the air, and is roughly divided into a split type air conditioner and an integrated type air conditioner. Among them, the indoor unit and the outdoor unit of the split type air conditioner are installed separately from each other, and the indoor unit of the split type air conditioner can be classified into vertical, wall-mounted or ceiling type air conditioners according to its installation structure and shape.

As shown in Figure 1, the existing air conditioner includes: a casing 1 for forming the appearance of the air conditioner and installing various components inside; an indoor heat exchanger 2 installed inside the casing 1 for connecting with indoor The air performs heat exchange to cool/heat the indoor air; at this time, the lower end of the indoor heat exchanger 2 is supported by a drainpan (not shown), and the upper end of the indoor heat exchanger 2 is fixed to the casing 1 by a fixing bracket 3 behind. The process of fixing the upper end of the indoor heat exchanger 2 with the fixing bracket 3 will be further described in detail below. First, the fixing bracket 3 is fixed to the rear surface 1a of the cabinet 1 by a coupling unit such as a screw. Then, put the indoor heat exchanger 2 into the casing 1 and fix the upper end of the indoor heat exchanger 2 to the fixing bracket 3, as shown in FIG. 1 .

However, in the existing air conditioner with the above-mentioned indoor heat exchanger fixing structure, since the fixing bracket 3 is only supported by the rear surface 1a of the casing 1, when the air conditioner is turned upside down for some reason (for example, when carrying products), At this time, since the gravity of the indoor heat exchanger 2 acts in the form of moment, the rear surface 1a of the casing is squeezed and deformed.

Moreover, in the existing air conditioner, the gravity of the indoor heat exchanger 2 is concentrated on the back of the casing 1a, so in order to firmly support the indoor heat exchanger, it is necessary to use more screws and fix the fixing bracket to the casing 1 in multiple places. The latter 1a, thus reducing the assembly efficiency of the product.

Detailed ways

Hereinafter, the embodiments provided by the present invention will be described in detail with reference to the accompanying drawings. Fig. 2 is a side sectional view of the structure of the air conditioner provided according to the present invention, and Fig. 3 shows that the fixing bracket of the air conditioner provided according to the present invention is fixed to the casing Fig. 4 is a schematic diagram of enlarged part "A" of Fig. 2. Moreover, FIG. 5 is an exploded schematic view showing another embodiment in which the fixing bracket of the air conditioner is fixed to the casing according to the present invention.

As shown in FIGS. 2 to 4 , the air conditioner provided by the present invention is composed of a bottom 11 , a casing 20 , a front panel 12 , and an upper cover 13 , thereby having a main body 10 forming the overall appearance of the air conditioner. The upper part of the front panel 12 forms a discharge port 12a for discharging cooled or heated indoor air, and two sides of the lower part form suction ports 12b for inhaling indoor air.

The cabinet 20 includes a rear panel 21 forming the rear of the air conditioner, and side panels 22 bent forward from both sides of the rear panel 21 to form side surfaces of the air conditioner. The front and top of the cabinet 20 are opened, and the opened front and top are joined to the front panel 12 and the top cover 13, respectively. The upper end of the casing 20 is formed with an edge 23 bent toward the inside of the casing 20, and this edge 23 is composed of a rear edge 23a formed on the casing rear panel 21 side and a side edge 23b formed on the side panel 22 side.

The inner upper part of the casing 20 is provided with an indoor heat exchanger 30, which exchanges heat with the indoor air sucked through the suction port 12b to cool or heat the indoor air. A powered exhaust unit 40 is used to circulate the room air. At this time, the exhaust device 40 includes a centrifugal exhaust fan 41 , a motor 42 for driving the exhaust fan 41 , and a fan case 43 for guiding the exhausted air to the indoor heat exchanger 30 side.

The indoor heat exchanger 30 is obliquely arranged in the upper space inside the casing 20 to exchange heat with the refrigerant when the air passes through. The lower end of the indoor heat exchanger 30 is supported by a drain pan 31, and the indoor heat The upper end of the exchanger 30 is fixed to the case 20 by a fixing bracket 50 .

As shown in FIG. 3 , the fixing bracket 50 provided by the present invention is fixed on at least two sides of the casing 20 through coupling units 60 such as screws. At this time, since the gravity of the indoor heat exchanger 30 supported by the cabinet 20 through the fixing bracket 50 is not concentrated on the rear panel 21 of the cabinet but dispersed in various directions, it is possible to prevent the rear of the cabinet when the air conditioner is turned upside down. The phenomenon that the panel 21 is extruded and deformed. Also as described above, if the gravity of the indoor heat exchanger 30 is distributed to parts of the cabinet 20, the indoor heat exchanger 30 can be effectively supported even with a small number of coupling units, thereby improving product assembly efficiency.

The fixed bracket 50 has a bracket rear panel 51 and a bracket side panel 52. When the fixed bracket 50 is combined with the casing 20, the bracket rear panel 51 and the bracket side panel 52 contact the rear panel 21 and the side panel 22 of the casing respectively, and have The bracket edge 53 that contacts the edge 23 of the housing. When the fixing bracket is combined with the casing 20 , the bracket rear panel 51 is fixed to the rear panel 21 of the casing through the coupling unit 60 , and the bracket edge 53 is combined with the casing edge 23 .

The bracket edge 53 is formed by a bracket rear edge 53a formed on the bracket rear panel 51 side and a bracket side edge 53b formed on the bracket side panel 52 side, the bracket rear edge 53a corresponds to the rear edge 23a of the casing, and the bracket side edge 53b corresponds to The side edge 23b of the casing. In order to effectively disperse the gravity of the indoor heat exchanger 30 when the bracket edge 53 is combined with the casing edge 23, the coupling unit 60a preferably connects the casing side edge 23b and the fixing bracket side edge 53b, as shown in FIG. 3 .

However, as shown in FIG. 5 , the coupling unit 60b may also be coupled to the rear edge 23a of the casing and the rear edge 53a of the fixing bracket.

Moreover, the fixing bracket 50 has a heat exchanger supporting part 54 with one side combined with the bracket rear panel 51 , and the other side of the heat exchanger supporting part 54 is used for fixing the indoor heat exchanger 30 . At this time, if the same connecting unit 60c is used to connect the heat exchanger supporting portion 54, the bracket rear panel 51 and the casing rear panel 21, the cost of parts can be reduced and the assembly efficiency of the product can be improved because the number of connecting units can be reduced.

In summary, the present invention prevents the gravity of the indoor heat exchanger from concentrating on a specific part of the casing by improving the fixing structure of the fixing bracket, thereby preventing damage to the casing due to the gravity of the indoor heat exchanger.

Also, according to the present invention, the indoor heat exchanger can be firmly fixed to the casing by using relatively few coupling units, thereby improving the assembly efficiency and production efficiency of products.
