Description

  The present invention relates to an air conditioner, and particularly to an air conditioner including a heat exchanger configured by connecting a plurality of heat exchanger portions.

  A conventional heat exchanger provided in this type of air conditioner is configured by connecting a plurality of heat exchanger portions as shown in FIG. 5 (see, for example, Patent Document 1).

FIG. 5 is a diagram illustrating a connection configuration of the heat exchanger of the conventional air conditioner described in Patent Document 1, in which the heat exchanger 10 provided in the conventional air conditioner includes a plurality of heat exchangers 10. The heat exchanger portions 10a and 10b are formed by being connected in a bent shape, and the connection plates 11a and 11b protrude from the heat exchanger portions 10a and 10b so that the heat exchanger portions 10a and 10b can be connected by being bent at a predetermined angle. It is installed. A claw 12a is formed on one of the overlapping connecting plates 11a and 11b, for example, the connecting plate 10a, and a hole 12b into which the claw 12a is fitted is formed on the other connecting plate 11b. After the claws 12a are fitted into the holes 12b and temporarily fixed, both the heat exchanger portions 10a and 10b are connected by screws (not shown).
Japanese Patent Laid-Open No. 09-145145 (FIG. 4)

  However, in the configuration of the conventional air conditioner, since the clearance between the claw and the hole is necessarily required, there is a problem that the wind enters from the gap between the claw and the hole and condenses on the cruz flow fan.

  The present invention solves the above-described conventional problems, and provides an air conditioner that can prevent wind from entering at a connecting portion of a heat exchanger portion and prevent condensation on a crossflow fan with a simple configuration. The purpose is to provide.

  In order to solve the above-described conventional problems, an air conditioner according to the present invention is an air conditioner having a heat exchanger in which a plurality of heat exchanger parts are connected at a predetermined angle, and the heat exchanger part. Each includes a fixing plate so as to be fixed at the predetermined angle. A claw is formed on one of the fixing plates that overlap each other, and a recess and a temporary fitting are fitted on the other fixing plate. A temporary claw for fastening is formed, the claw is fitted into the recess, and the heat exchanger part is fixed with screws, and the heat exchanger part is connected with a simple configuration. Prevents the intrusion of wind at the section and prevents condensation on the crossflow fan.

  The air conditioner of the present invention has an effect that it is possible to prevent wind from entering at the connecting portion of the heat exchanger portion and prevent dew condensation on the cross flow fan with a simple configuration.

In a first aspect of the present invention, in the air conditioner having a heat exchanger in which a plurality of heat exchanger portions are connected at a predetermined angle, each of the heat exchanger portions is fixed at the predetermined angle. And a claw is formed on one of the fixing plates that overlap each other, and a recess that fits into the claw and a temporary claw for temporarily fixing are formed on the other fixing plate. The claw is fitted into the recess and the heat exchanger part is fixed with a screw. With a simple configuration, the intrusion of the wind at the connecting part of the heat exchanger part is prevented and the cross flow fan is obtained. Condensation can be prevented.

  In the second invention, in particular, the claws and recesses of the first invention are provided with slopes having an angle, and when the claws are fitted into the recesses, the slopes provided on them guide each other, The mating work becomes easy.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited by this embodiment.

(Embodiment 1)
1 is a cross-sectional view of an air conditioner according to Embodiment 1 of the present invention, FIG. 2 is a side view of a heat exchanger and a fixed plate of the air conditioner, and FIG. 3 is a connection state of the fixed plate. It is a perspective view.

  1 to 3, a heat exchanger 2, a cross flow fan 3, and a blower circuit 4 are disposed inside the air conditioner body 1.

  The heat exchanger 2 includes a plurality of heat exchanger portions 2a, 2b, 2c, and 2d, and each of the heat exchanger portions 2a, 2b, 2c, and 2d is a fixed plate so as to be fixed at a predetermined angle. 5, one fixing plate 5 b of the fixing plates 5 a and 5 b overlapping each other is formed with a claw 6 to be fitted, and the other fixing plate 5 a has a recess 7 to which the claw 6 is fitted, Temporary fastening claws 8 for temporary fastening are formed, the claws 6 are fitted into the recesses 7, and both heat exchanger portions 2a and 2b are fixed with screws (not shown). With the configuration, it is possible to obtain an effect that it is possible to prevent the intrusion of wind at the connecting portion of the heat exchanger portions 2a and 2b and to prevent dew condensation on the cross flow fan 3.

(Embodiment 2)
FIG. 4 is a perspective view showing a connected state of the heat exchanger part of the air conditioner according to Embodiment 2 of the present invention. In addition, about the same part as the air conditioner in the said 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  In the present embodiment, as shown in FIG. 4, a claw 6 to be fitted is formed on one of the fixing plates 5 a and 5 b that overlap each other, and a concave portion 7 to be fitted to the claw 6 is formed on the other fixing plate. And a claw 8 for temporary fixing to be temporarily fixed, and in order to facilitate the overlapping of the fixing plates 5a and 5b, the engaging claw 6 is provided with a slope 9a having a certain angle, The recessed portion 7 to be fitted is also provided with an inclined surface 9b having an angle similar to the fitting claw 6, and after the fixing plates 5a and 5b are fitted and temporarily fixed, both heat exchangers are provided. It is possible to obtain an effect that the portions 2a and 2b are simply configured to be fixed with screws and the wind can be prevented from entering and the dew condensation on the cross flow fan 3 can be prevented.

  As described above, the fixing method of the heat exchanger according to the present invention has a simple configuration and can prevent the intrusion of the wind, so that it can be used for equipment such as a device having a plurality of heat exchanger parts mounted therein. Is also applicable.
