Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a mounting structure for a connecting part between a combustion heat exchanger and a burner in an outdoor unit equipped with a refrigerant heating device for a dual purpose air conditioner. .

[Prior art]

The structure of the connection between the burner and the combustion heat exchanger in a conventional air conditioner of this type will be explained with reference to FIGS. 1 to 3.
is a combustion machine, 2 is a burner, and combustion gas outlet 3 of burner 2
is formed to protrude from the side wall surface of the burner 2 in a cylindrical shape.

The combustion gas intake port 5 of the combustion heat exchanger 4 is connected to the air outlet 3.
It is formed to protrude in a cylindrical shape opposite to the air outlet 3, and forms a cylinder slightly larger than the cylindrical diameter of the air outlet 3.
are mated.

The combustion gas is blown into the combustion heat exchanger through the outlet 3 of the burner 2, heats the refrigerant by the heat exchanger 4a, and is discharged from the outdoor unit 10 through the exhaust section 6.

Reference numeral 7 is an elastic heat insulating material that is attached to the outlet 3 of the burner 2, and the end face of the combustion gas intake port 5 is slightly bitten into the heat insulating material to prevent leakage of the combustion gas.

The conventional type had the structure of the connecting portion as shown above, and had the following drawbacks.

In addition, the insulation material 7 is likely to be damaged by rubbing against the end surface of the intake port 5 due to vibrations during transportation, and gaps are likely to occur due to uneven pressure between the end surface of the intake port 5 and the insulation material 7.
Since the cylindrical part requires a certain length, it is necessary to perform the drawing process in several stages, or if a separate piece is attached, it is necessary to use brazing, etc. to completely seal the connection part of the separate piece. It is necessary, the cost is high, and the workability is poor.

[Summary of the idea]

The present invention is intended to eliminate the above-mentioned drawbacks.

[Example of idea]

The structure of the connection part of the present invention will be explained with reference to Figs. 1 to 2 and Fig. 4. 1 is a combustion machine, 2 is a burner,
The air outlet 3 is formed in a cylindrical shape.

The combustion gas inlet 5 of the combustion heat exchanger 4 has a through hole 5a formed in the side wall 8, which is slightly larger than the outlet 3 of the burner 2.

The outlet 3 of this burner 2 is inserted into the intake port 5, and 2 to 3 rIrI
It is inserted so that it penetrates through n.

An elastic, high-temperature-resistant heat insulating material 10 is formed in a ring shape and installed between the side wall 8 of the combustion heat exchanger and the side panel 9 of the outdoor unit. Similarly elastic high temperature resistant insulation material 11 between
is formed into a ring shape and attached.

The combustion gas passes through a combustion heat exchanger, heats the refrigerant, and is discharged to the outside of the outdoor unit 12 from the exhaust section 6.

13 is a compressor that constitutes a refrigerant circuit; 14 is an outdoor heat exchanger; and 15 is a blower that forces air into the outdoor heat exchanger 14.

[Effect of idea]

This invention has the above-mentioned configuration, and the heat insulating material is in contact with the combustion heat exchanger and the side panel, and the side panel and the part, so there is less damage and contact is made over a wide area. Therefore, a sufficient sealing structure can be achieved even with a heat insulating material with low elasticity, and the intake of the combustion heat exchanger requires only a simple through hole, which is very advantageous in terms of cost and has good workability. It has many advantages such as improved productivity.

[Brief explanation of the drawing]

Figure 1 is a plan view of a heating and cooling air conditioner with a combustor, Figure 2 is a longitudinal sectional view of the air conditioner with a combustor, and Figure 3 is a diagram of the connection between a conventional burner and combustion heat exchanger. FIG. 4 is a partially detailed sectional view of a connecting portion according to the present invention. In the figure, 1 is a combustor, 2 is a burner, 3 is a burner outlet, 4 is a combustion heat exchanger, 5 is a combustion gas intake port, 6 is an exhaust part, 7 is a heat insulator, and 8 is a combustion heat exchanger The side walls of the container include a side panel 9, a high temperature insulating material 10, and a heat insulating material 11.

Claims (1)

[Scope of utility model registration request] In a heat pump type heater equipped with a refrigerant heating device, in which the combustion machine and the combustion heat exchanger are configured to be detachably separated, through-holes are drilled in the side panel of the outdoor unit and the side wall of the combustion heat exchanger.
