Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an auxiliary heater mounting device for an air conditioner.

BACKGROUND ART Conventionally, heat pump type air conditioners such as individual air conditioners use an auxiliary heater to supplement heating. This will be explained based on FIG. An indoor unit room 2 is configured in the main body 1 of the individual air conditioner, and an indoor blower 3 is installed in this indoor unit room 2.
and an indoor heat exchanger 4. The indoor heat exchanger 4 is fixed with its upper part tilted toward the rear side and is tilted, and is held by a lower support plate 5 and an upper support plate 6. On the leeward side of this indoor heat exchanger 4, an auxiliary heater 9 consisting of a frame 8 holding a large number of heater elements 7 is fixed to L-shaped holding plates 10 provided on both sides. That is, the holding plate 10 is an L-shaped piece that is fixed to the side plate 11 by welding 12, and an insulating material (not shown) is placed on top of the holding plate 10.
etc., and fixed with screws 13 through the operation of indoor blower 3 to heat air generated by condensation heat passing through indoor heat exchanger 4 through auxiliary heater 9,
This heated high-temperature air was blown into the room from the outlet 14.

Problems to be Solved by the Invention In such a conventional configuration, the L-shaped holding plates 10 are fixed to the side plates 11 on both sides by welding 12 in order to attach the auxiliary heater 9, which increases the number of manufacturing steps. There was a problem in that retaining plates to be fixed on both sides were also required, resulting in an increase in the number of parts.

This invention solves these problems,
The purpose is to fix an auxiliary heater without using a holding plate.

Means for Solving the Problem In order to solve this problem, the present invention provides an indoor heat exchanger formed by orthogonally forming plate fins and tubes, and a fin fixing piece and a heater on both sides of the indoor heat exchanger. The heat exchanger side plate is formed of a fixing piece and a heat exchanger side plate, and the fin fixing piece protrudes from the leeward end surface of the indoor heat exchanger and bends the heater fixing piece.

Effect With this configuration, the plate fin is fixed on both sides of the plate fin by the fin fixing pieces of the heat exchanger side plate, and the heater fixing piece is folded at the place where the fin fixing piece protrudes from the leeward end surface of the indoor heat exchanger. The auxiliary heater is fixed to the heater fixing piece by bending, and the auxiliary heater is fixed while maintaining the distance between the leeward end face and the auxiliary heater.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. In Fig. 2, the main body 17 of the air conditioner has an indoor unit room 18, an indoor fan 19 is located below, and a plate fin 2 is located above.
0, a tube 21 (dotted line in FIG. 2), and an indoor heat exchanger 23 formed by a heat exchanger side plate 22.
is installed at an angle. This slope slopes forward at the bottom and backward at the top. The indoor heat exchanger 23 is tilted and fixed to the lower cover plate 24 and the upper cover plate 25, and in this fixed state, the ends of the heat exchanger side plates 22 on both sides are in contact with the inside of the side plates 26. configured. In FIG. 2, the heat exchanger side plate 22 includes a fin fixing piece 27 and a heater fixing piece 28, and is formed in an L shape, and the fin fixing piece 27 protrudes upward from the leeward end surface 29 of the fin 20, and substantially The heater fixing piece 28 is bent outward so as to protrude by about 2 cm to 3 cm. An auxiliary heater 32 holding a plurality of heater elements 30 by a frame 31 is attached to the heater fixing piece 28 with screws 3 through an insulating material 33.
It is fixed by 4.

In the above configuration, the indoor heat exchanger 23 is tilted and fixed above the indoor unit room 18, and on both sides of the indoor heat exchanger 23, the outer end surface of the heat exchanger side plate 22, that is, the end surface of the heater fixing piece 28 is connected to the side plate 2 of the main body. It is located so that it is in contact with the Then, with the heater fixing piece 28 of the heat exchanger side plate 22 facing diagonally upward, the auxiliary heater 32 to which the heater element 30 has already been fixed is fixed to the heater fixing piece 28 with an insulating material 33 interposed therebetween. piece 28 and frame 3
1 and are insulated and fixed with screws 34.

Effects of the Invention As is clear from the description of the above embodiments, the present invention has a heat exchanger side plate constituting an indoor heat exchanger formed into an L shape, one of which is a fin fixing piece for fixing the fin, and this fin fixing piece. is made to protrude from the leeward end face of the indoor heat exchanger and is bent as a heater fixing piece for attaching the auxiliary heater, and the auxiliary heater is fixed to the heater fixing piece, so that the auxiliary heater cannot be fixed like the conventional method. This eliminates the need for metal fittings, reduces the number of parts, eliminates welding man-hours, and reduces costs. Furthermore, since the fin fixing piece is made to protrude from the leeward end surface so as to maintain an appropriate distance between the leeward end surface and the auxiliary heater, there is no possibility of contact between the fins on the leeward end surface and the heater element, resulting in electrical leakage due to contact. There are no accidents, and since the end of the heater fixing piece is brought into contact with the side plate, air leakage can be prevented.
