Description

  The present invention relates to an air conditioner. More specifically, the present invention relates to a balance between weight reduction and cost reduction technology by reinforcing the center portion of a side plate of a heat exchanger, and reinforcement technology.

The conventional air conditioner (outdoor unit) has a heat exchanger with a side plate divided on the top and bottom on one side. A heat exchanger is installed, and a heat exchanger bent into a substantially concave shape or a substantially L shape is provided over the back side and one side or both sides of the compressor, and a blower is provided facing the back side of the heat exchanger. The electric component housing the electric component is fixed to the upper end of the side plate provided on both sides of the heat exchanger, and a terminal board connected to the electric component is provided at one lower portion of the electric component, and one side of the heat exchanger In which a mounting plate with a connection valve attached is provided, and an outer cylinder is provided on the bottom plate,
The heat exchanger is provided with a slit extending horizontally from one side end, and is formed into a substantially concave shape or a substantially L shape by bending the lower side and / or the other side of the slit. Further, the side plate corresponding to one side of the heat exchanger is divided at a position facing the slit and is provided at the upper and lower portions while being bent substantially in parallel from the inside. (For example, refer to Patent Document 1).

  The side plate has the same size as the fins constituting the heat exchanger and is made of a steel plate having a thickness of about 0.7 mm, so that, for example, the heat exchanger with the fins is seated. It has a configuration with increased strength so that it does not deform due to bending.

  However, although the side plate is divided into upper and lower portions at a position facing the slit, the side plate has a configuration provided corresponding to the entire side of one side of the heat exchanger. While the strength of the exchanger is enhanced, there is a problem that the weight increases due to the use of a steel plate, making it difficult to reduce the weight, and disadvantageous in terms of cost. .

JP-A-9-153565

  Therefore, the present invention has been made to solve the above-described problems, and the object thereof is to reduce the weight and reduce the weight of the heat exchanger due to the fact that the side plates of the heat exchanger are composed of an upper side plate and a lower side plate that are spaced apart from each other.

  As shown in the figure, an outdoor unit of an air conditioner according to the present invention partitions a top plate 1 into a heat exchanger chamber and a compressor chamber by a partition plate 2, and a side plate 3 on the side of the heat exchanger chamber. A heat exchanger 4 provided to the heat exchanger 4 and a blower (not shown) opposed to the heat exchanger 4, a compressor 6 and an electrical component box 7 are provided in the compressor chamber, and an outer cylinder 5 is provided on the bottom plate 1. It has a configuration provided.

  In addition, as an outdoor unit of the air conditioner according to the present invention, in addition to the basic configuration described above, for example, when a horizontal compressor is adopted, an air passage is provided in the bottom plate 1 although not shown. Those having a configuration in which a partition plate for forming is provided are recognized (for example, registration number 3009045), or those having a configuration in which a member similar to the partition plate is not provided (for example, Japanese Patent Application Laid-Open No. 2003-151866). 2000-88292).

  In the configuration in which the partition plate is not provided, the side plate 3 is fixed to the upper and lower portions of the outer body 5 so as to fix the heat exchanger 4 and the strength of the heat exchanger 4 can be increased. However, here, the side plate 3 is arranged so as to be vertically separated from each other and fixed to the upper and lower portions of the partition plate 1 and the upper and lower portions of the outer body 5 based on the attached drawings. The embodiment will be described based on a configuration in which the heat exchanger 4 is fixed and the strength of the heat exchanger 4 can be increased.

  In addition, the heat exchanger 4 is fixed to the partition plate 1 and the outer body 5 via the side plates 3 that are spaced apart from each other up and down. You may make it fix to the said partition plate 1 or the said outer cylinder 5 via the member (For example, a member called a fixing metal fitting) which has the function for fixing the heat exchanger 4. FIG.

  As shown in FIGS. 3 (A) and 3 (B), the heat exchanger 4 includes a large number of fins 4a arranged in parallel at equal intervals, and a heat transfer tube 4b orthogonal to the fins 4a. The end portion of the heat transfer tube 4b is connected by a hairpin-like (U-shaped) connecting tube 4c, and the side portion includes the side plate 3 made of a steel plate having a thickness of about 0.7 millimeters, As shown in FIG. 3C, for example, the heat exchange is performed by screwing screws through the through holes c and c ′ into the screw holes b of the upper side plate 3a and the lower side plate 3b constituting the same side plate 3. A container 4 is fixed to the partition plate 1 and the outer trunk 5.

  The side plate 3 is divided into an upper side plate 3a and a lower side plate 3b by cutting a cut portion 3c in the longitudinal direction indicated by a two-dot chain line in FIGS. 3 (A) and 3 (B). It is arranged at the side of the exchanger 4 in a state of being vertically separated, so that the amount of steel plate used as a material can be greatly reduced, and the central portion of the side plate 3 of the heat exchanger 4 is cut off. By doing so, it is configured to effectively reduce the weight and cost.

  The upper side plate 3a and the lower side plate 3b may be formed in different shapes as shown in FIG. 3 (A), or in the same shape as shown in FIG. 3 (B). You may make it standardize by forming.

  By forming the upper side plate 3a and the lower side plate 3b in the same shape, it is possible to greatly reduce the size without increasing the number of molding dies, and as described above, the material of the side plate 3 In addition to drastically reducing the amount of steel sheet used and reducing the weight and cost, the mold and the upper side plate 3a and the lower side plate 3b can be easily transported and managed. .

  The upper side plate 3a and the lower side plate 3b are provided with a plurality of insertion holes a into which the heat transfer tubes 4b are inserted, and the heat exchanger is inserted by inserting the heat transfer tubes 4b into the plurality of insertion holes a. 4 can be attached accurately so that play does not occur on the side portion, and can be reinforced so that the fins 4a are not buckled by being fixed to the outer body 5 or the partition plate 2. Become.

  The outer cylinder 5 includes a front panel 5a made of a synthetic resin or a sheet metal made of a synthetic resin so as to face a blower (not shown) provided in the heat exchanger chamber, and the heat exchanger chamber and the compressor chamber. Sheet metal side panel 5b and rear panel 5c continuously formed so as to cover the side portion and a part of the rear surface, and a sheet metal upper surface panel covering the heat exchanger chamber and the compressor chamber. It is composed of 5d.

Here, as Example 1, the upper side plate 3a and the lower side plate 3b are fixed to the back panel 5c of the outer body 5 so that the fin 4a can be reinforced so as not to be buckled. Whether this is done will be described with reference to FIGS. 4 (A) to 4 (C).
