Next, the assembly of the thus configured heat exchanger holding device for an air conditioner will be explained. First, with the air conditioner case 1 and the heat exchanger 2 stacked on top of each other, the pin 3 is inserted into the hole 9 provided in the tongue piece provided at the top of the air conditioner case 1. Then, the tip of the pin 3 is inserted across the fins of the heat exchanger 2 and between the pipes of the heat exchanger 2 as shown in FIG. is fixed. However, this alone is insufficient for fixing, so a seventh T-shaped portion at the tip of the heat exchanger fixing fitting 4 is attached to the U-shaped bent portion of the pipe on the left side of the heat exchanger 2.
As shown in the figure, this heat exchanger fixing fitting 4 is fixed to the air conditioner case 1 with screws 5 in a hooked state. Further, cover holders 7 bent into a U-shape are provided at the upper and lower ends of the soup scattering prevention cover 6, respectively, and the cover holders 7 are protruded from the side of the heat exchanger as shown in FIG. The soup scattering prevention cover 6 is attached to the heat exchanger 2 by being hooked onto the U-shaped bent portion of the pipe from both upper and lower sides.

[Problem that the invention attempts to solve]

Conventional heat exchanger holding devices for air conditioners are configured as described above, and as a result, the number of parts is extremely large and the number of assembly steps is also increased, making the device extremely expensive overall. There was a problem with getting used to it.

This idea was made in order to solve the above problems, and by constructing the heat exchanger holding device, which was conventionally composed of 5 types and 7 parts, by configuring it with 1 type and 1 part. The aim is to reduce the number of parts at once, significantly reducing assembly time and costs.

[Means for solving problems]

The heat exchanger holding device for an air conditioner according to this invention has an arch-shaped hole in one side of the air conditioner case that houses the heat exchanger, into which the U-shaped bent part of the pipe protruding from the side of the heat exchanger is inserted. A heat exchanger that is provided with a locking part having a locking part and a hook on the other side of the air conditioner case, and that wraps around the U-shaped bent part of the pipe that protrudes from the side of the heat exchanger on which the hook is provided. The heat exchanger is fixed to the air conditioner case by providing a rib on the fixture and hooking it onto the hook.

[Effect]

The heat exchanger holding device for an air conditioner according to this invention has a U-shaped bent part of a pipe that protrudes from the side of the heat exchanger into an arch-shaped hole in a locking part provided on the side of the air conditioner case. In addition, the U-shaped bent part of the pipe protruding from the other side of the heat exchanger is wrapped by the heat exchanger fixing fitting, and the ribs provided on the heat exchanger fixing fitting are It is fixed by hooking it onto a hook provided on the harmonizer case. For this reason, the number of parts constituting the heat exchanger holding device is significantly reduced compared to the conventional one.

[Example of idea]

An embodiment of this invention will be described below with reference to the drawings. In FIG. 1, reference numeral 10 denotes an air conditioner case, and a locking portion 11 projecting forward is integrally formed on the left side of the case. A heat exchanger 2 is provided on the side surface of this locking portion 11.
As shown in FIG. 2, an arch-shaped hole 11a into which the U-shaped bent portion of the pipe protruding from the side surface is inserted is provided. 12 is a key-shaped hook provided on the front part of the right end of the air conditioner case 10, and 13 is a hook that can wrap around the U-shaped bent portion of the pipe protruding from the other side of the heat exchanger 2. This is a heat exchanger fixture with a U-shaped cross section. This heat exchanger fixture 13 is
As shown in FIG. 4, a rib 14 is provided at a position that engages with the hook 12 when the pipe is mounted so as to wrap around the U-shaped bent portion of the pipe.

The thus configured heat exchanger holding device for an air conditioner is assembled as follows.
First, in the arch-shaped hole 11a of the locking part 11 provided at the left end of the air conditioner case 10,
Insert the U-shaped bent portion of the pipe protruding from the left side of the heat exchanger 2. By doing this, first, the left end of the heat exchanger 2 is connected to the air conditioner case 1.
It will be fixed to 0.

Next, a heat exchanger fixture 13 having a U-shaped cross section is attached to the U-shaped bent portion of the pipe protruding from the right side of the heat exchanger 2.
By attaching the pipe so that it wraps around the U-shaped bent part of the pipe, it is possible to prevent the condensation adhering to this part from scattering into the electrical parts box 8. Once the heat exchanger fixture 13 is attached to the right end of the heat exchanger 2 in this way, the heat exchanger fixture 13 is pressed against the air conditioner case 10 in that state.
In this way, the rib provided on the heat exchanger fixture 13 engages with the hook 12, and the heat exchanger fixture 13 fixes the right end of the heat exchanger 2 to the air conditioner case 10. Become. In other words, this heat exchanger fixture 13 has the function of fixing the heat exchanger 2 to the air conditioner case 10 and preventing the condensation from adhering to the U-shaped bent portion of the pipe protruding from the right side of the heat exchanger 2.
This has the effect of preventing the particles from scattering toward the electrical component box 8 side.

[Effect of idea]

As described above, according to this invention, the pipe protruding from the side of the heat exchanger is inserted into the arch-shaped hole in the locking part provided on the side of the air conditioner case.
The U-shaped bent portion of the pipe protruding from the other side of the heat exchanger is wrapped by the heat exchanger fixing fitting, and the heat exchanger fixing fitting is provided with a It is fixed by hooking the rib on the hook provided on the air conditioner case. For this reason, the number of parts constituting the heat exchanger holding device is significantly reduced compared to the conventional method, which has the excellent effect of significantly reducing costs.
