Description

[Detailed description of the invention] The present invention is configured so that air is supplied from above to a heating section using a horizontally cylindrical surface combustion burner and is sent into the room from below, and the combustion gas of the burner is heated by the heating section. The present invention relates to a heater configured to be mixed with air sent into a room from a heater, and provided with partition walls on the lateral side and above the burner to partition a combustion space and an air flow path.

The above-mentioned heater circulates indoor air from above to below the heating section, so it is capable of rapid heating and uniform heating of the entire room.Furthermore, since combustion gas is supplied into the room, heating with high thermal efficiency is possible. In addition, by making the burner a horizontally cylindrical surface-combustion burner and using a bulkhead to prevent the case from overheating, it is possible to make the burner smaller and shorter. In order to avoid burnout, the bulkhead had to be placed relatively far from the burner, and there was room for improvement in making the heater more compact.

In view of the above-mentioned circumstances, the present invention aims to make it possible to sufficiently reduce the size of the heater through extremely simple modification.

Next, the actual state of the present invention will be explained with reference to illustrative drawings.

A horizontal cylindrical surface combustion burner 1 is provided inside a case 2, an indoor air inlet 3 is formed in the upper part of the rear wall of the case 2, and a heated air outlet 4 for indoor air is formed in the lower part of the front wall. A conduit 6 with a fan 5 branched and connected to the upper space of the case 2 and the burner 1 is provided to circulate indoor air from above to below in the heating section A of the burner 1, and to circulate the combustion gas of the burner 1. A heater is configured to supply heated air mixed with heated air into a room.

A combustion space 7 is provided laterally and above the burner 1.
Partition walls 9a and 9b are provided to partition the air flow path 8 and the air flow path 8, thereby preventing destabilization of combustion in the burner 1 and overheating of the case 2 due to the air flow. In addition, an opening 10 is provided at the boundary between the lateral partition wall 9a and the upper partition wall 9b to allow air from the pipe to flow into the combustion chamber gap 7, so that the lateral chamber 9a is protected from burnout by being cooled from both sides. It is designed to be protected.

The surface combustion burner 1 is constructed by winding and fixing a wire mesh 1b around a punched metal 1a formed into a cylindrical shape, and ejecting fuel gas in a direction facing the upper partition wall 9b. The plate-shaped body 11 that prevents
The upper partition wall 9b is configured to be positioned and fixed on the inner circumference thereof to protect the upper partition wall 9b from burnout.

The nozzle 12 is for supplying gas fuel such as city gas to the burner 1, and the orifice 13 is for supplying gas fuel such as city gas to the burner 1.
The amount of air supplied to the burner 1 is maintained at an appropriate amount to stabilize surface combustion.

In forming the opening 10, various configuration changes are possible, such as arranging small holes or relatively short elongated holes in parallel.

The plate-shaped body 11 can be modified in various configurations, such as one that continues integrally with the punched metal 1a, or one that is provided with small holes with an aperture ratio much smaller than that of the punched metal 1a.

In summary, the present invention provides the above-mentioned heater with an opening 10 at the boundary between the lateral partition wall 9a and the upper partition wall 9b of the burner 1 to allow air to flow into the combustion space 7; Burner 1
It is characterized in that a plate-like body 11 is attached for restricting the fuel gas to be ejected in a direction opposite to the upper partition wall 9b.

That is, while forming the opening 10, the plate-like body 1
Even with an extremely simple modification of just adding 1,
Even if the bulkheads 9a and 9b are placed very close to the burner 1, they can be protected from burnout, and the heater can be made even more compact. Overall, it is not only functionally superior as mentioned above, but also A heater that is extremely superior in terms of installation and handling was obtained.
