  FIG. 1 is a perspective view showing the inside of the air conditioner 100 (indoor unit) with the front panel removed. The heat exchanger fixing plate 1 for fixing the heat exchanger 13 to the main body 10 is omitted. FIG. 1 is a view of the air conditioner 100 as seen from slightly above the left front.

  The air conditioner 100 is divided into an indoor unit and an outdoor unit. The indoor unit is a wall-mounted type. Here, the indoor unit is referred to as an air conditioner 100.

  The air conditioner 100 includes a heat exchanger 13 that exchanges heat with indoor air in which a refrigerant of a refrigeration cycle flows inside a housing that includes a main body 10 and a front panel, and a blower 11 that sends conditioned air into the room. Stored.

  The blower 11 is a cross flow fan, also called a crossflow fan. The air is sucked from one radial direction of the impeller and blown from the radial direction on the opposite side. Since it is easy to increase the length of the air outlet, it is suitable for the air conditioner 100 (indoor unit).

  A drain pan 12 that receives drain water (frost or the like) generated in the heat exchanger 13 is provided below the heat exchanger 13.

  The configuration of the heat exchanger 13 will be described with reference to FIG. The heat exchanger 13 is mainly composed of heat transfer tubes 6 and heat radiation fins 7 arranged in two rows. A plurality of heat radiating fins 7 are laminated through a plurality of heat transfer tubes 6 obtained by bending a copper tube by 180 °. At this time, a large number of heat radiation fins 7 are stacked with the hairpin portions 6a of the plurality of heat transfer tubes 6 bent by 180 ° (U-shaped end portions protruding from the heat radiation fins of the heat transfer tubes) facing down.

  An end plate (not shown) thicker than the heat radiating fins 7 is attached to the end of the laminated heat radiating fins 7 opposite to the hairpin portions 6a (the other end protruding from the heat radiating fins of the heat transfer tubes). Although the opposite side of the hairpin portion 6a of the heat transfer tube 6 is open, the openings of the adjacent heat transfer tubes 6 are connected by another connection copper tube bent into a U shape.

  An example of the heat exchanger 13 shown in FIG. 2 has a first heat exchanging portion 13a and a second heat exchanging portion 13b, and the front side heat that is bent into a substantially U shape by the second bent portion 14b. It consists of an exchanger 13c and a back side heat exchanger 13d (referred to as a third heat exchange unit).

  The first heat exchanging part 13a and the back side heat exchanger 13d of the front side heat exchanger 13c are bent at the first bent part 14a. The front side heat exchanger 13c and the back side heat exchanger 13d may be separate. In the case of a separate body, the first heat exchanging part 13a and the back side heat exchanger 13d of the front side heat exchanger 13c are in contact with each other.

  A method for fixing the heat exchanger 13 to the main body 10 will be described. The heat exchanger 13 is fixed to the main body 10 by engaging or screwing both ends of the heat exchanger 13.

  A method for fixing the end of the heat exchanger 13 opposite to the hairpin portion 6a to the main body 10 will be briefly described. As already described, an end plate thicker than the heat radiating fins 7 is provided at the end of the heat exchanger 13 opposite to the hairpin portion 6a. Therefore, a fixing component (for example, metal) is fixed to the end plate with a screw or the like. Then, by engaging the fixed component with the main body 10, the end of the heat exchanger 13 opposite to the hairpin portion 6 a is supported by the main body 10.

  As shown in FIG. 3, the end of the heat exchanger 13 on the hairpin portion 6 a side is fixed to the main body 10 using a resin heat exchanger fixing plate 1.

  This embodiment is characterized by the structure of the heat exchanger fixing plate 1. The end of the heat exchanger 13 on the side of the hairpin 6 a faces the back side of the plate-like base 1 a of the heat exchanger fixing plate 1. And the edge part by the side of the hairpin part 6a of the heat exchanger 13 is inserted in the back surface side of the plate-shaped base part 1a of the heat exchanger fixing plate 1. FIG.

  The configuration of the heat exchanger fixing plate 1 will be described with reference to FIGS. 4 and 5. The material of the heat exchanger fixing plate 1 is resin. For example, ABS resin is used. ABS resin is a copolymer composed of three types of monomers: acrylonitrile (ACRYLONITRILE), butadiene (BUTADIENE), and styrene (STYRENE).

  PP resin (polypropylene resin) is also used. PP resin looks similar to polyethylene but is harder and more tensile than polyethylene. The specific gravity is also 0.9 to 0.92, which is the lightest among general-purpose plastics. However, it is very strong against bending while being hard. Therefore, PP resin is used when using a hinge.

  However, resins other than ABS resin and PP resin can also be used.

  The heat exchanger fixing plate 1 is a resin molded product having a thickness of 1.5 to 2 mm using the above resin.

  The heat exchanger fixing plate 1 is erected so that the first outer wall 2a and the inner wall 3 are along the side surface shape of the heat exchanger 13 on the back surface side (heat exchanger 13 side) of the plate-like base 1a. .

  The first outer wall 2a, the inner wall 3, and the plate-like base 1a form a first groove 4a (an example of a groove) into which the hairpin part 6a of the heat exchanger 13 is inserted.

  The first outer wall 2a is provided with an engaging claw 5 that engages with the inner side of the hairpin portion 6a of the heat exchanger 13 on the inner side thereof.

  The heat exchanger fixing plate 1 includes a bearing holding portion 16 that holds the bearing portion 11a (see FIG. 1) of the blower 11. The bearing holding portion 16 has a substantially semicircular ring shape, and has a recess formed inside.

  Inside the inner wall 3, a dew receiving rib 15 that receives dew from the heat exchanger 13 is erected. The height of the dew receiving rib 15 is higher than the height of the inner wall 3.

  A plurality of reinforcing ribs 17 connected between the dew receiving ribs 15, between the dew receiving ribs 15 and the bearing holding portion 16, etc. are erected from the plate-like base portion 1 a inside the dew receiving rib 15.

  The first bent portion 14a between the first heat exchange portion 13a and the rear heat exchanger 13d of the front heat exchanger 13c of the heat exchanger 13 passes through the room air without passing through the heat exchanger 13. To do. Therefore, in general, a short-circuit suppressing member that prevents indoor air from passing through the heat exchanger 13 is provided. A short-circuit suppressing member fixing portion 18 for fixing the short-circuit suppressing member is provided on the heat exchanger fixing plate 1 so as to substantially face the first bent portion 14a.

  Here, the heat exchanger 13 includes a first heat exchanging portion 13a and a second heat exchanging portion 13b, and the front heat exchanger 13c is bent into a substantially U shape by the second bent portion 14b. And the rear side heat exchanger 13d are shown.

  FIG. 7 shows an engaged state between the two rows of hairpin portions 6 a of the heat exchanger 13 and the engaging claws 5 of the heat exchanger fixing plate 1.

  When inserting the two rows of hairpin portions 6 a of the heat exchanger 13 into the first groove 4 a of the heat exchanger fixing plate 1, the two rows of hairpin portions 6 a are connected to the engaging claws 5 and the inner wall 3 of the heat exchanger fixing plate 1. It is pushed in between. The engaging claw 5 (first outer wall 2a) and the inner wall 3 are bent outward by the force with which the hairpin portion 6a is pushed. If it is difficult to insert the two rows of hairpin portions 6a of the heat exchanger 13 into the first groove 4a of the heat exchanger fixing plate 1, the size of the opening 19 may be adjusted, as shown in FIG. As shown, slits 24 can be provided on both sides of the engaging claw 5 for adjustment. In FIG. 4, only the slit 24 on one side is shown. By providing the slit 24 and the opening 19, the engagement claw 5 can be easily bent and can be easily engaged with the hairpin portion 6 a.

  When the hairpin portion 6a is further pushed in, the inside of the hairpin portion 6a engages with the engaging claw 5, and the two rows of hairpin portions 6a are firmly held by the engaging claw 5 and the inner wall 3.

  The engaging claws 5 formed on the first outer wall 2a of the heat exchanger fixing plate 1 are connected to the first heat exchange part 13a of the front side heat exchanger 13c and the second heat exchange of the front side heat exchanger 13c. An example is shown in which one unit is provided for each of the unit 13b and the back side heat exchanger 13d. Although this form is the simplest and the engagement is strong and preferable, the following forms are also possible.

  That is, the engaging claws 5 are made to correspond to the first heat exchange part 13a of the front side heat exchanger 13c, the second heat exchange part 13b of the front side heat exchanger 13c, and the rear side heat exchanger 13d. Also, a configuration in which a plurality of each is provided is also possible.
