Description

[Detailed Description of the Invention] The present invention relates to an improvement of a hot-air heater, and is aimed at improving reliability and maintainability.

Generally, hot air heaters are configured by installing a heat exchanger inside the housing and installing a hot air fan at the bottom of this heat exchanger, and the air from the hot air fan is heat exchanged with the heat exchanger. It is designed to blow out to the outside from the blow-off opening on the front of the housing.

The air from the hot air fan is used as cooling air for functional components such as an ignition heater provided at the front of the lower part (combustion section) of the heat exchanger.

In other words, parts such as the igniter are heated to high temperatures by conductive heat or radiant heat from the heat exchanger and are susceptible to heat loss, so to prevent this, the warm air fan blows air onto them. .

However, the air from the hot air fan does not hit functional parts such as the ignition heater properly, and a sufficient cooling effect cannot be obtained, resulting in a high degree of heat loss.

Furthermore, if this functional component suffers heat loss, it cannot be repaired or replaced without removing the front panel of the casing, making maintenance extremely difficult.

The present invention has been made in view of these points, and eliminates the above-mentioned drawbacks of the conventional apparatus by utilizing a hot air blowing opening provided on the front plate of the housing.

One embodiment of the system will be described below with reference to the drawings. 1 is a casing of a warm air heater, 2 is a plate-shaped frame whose interior is divided into two upper and lower chambers, and a ventilation hole 3 is formed approximately in the center. It is.

Reference numeral 4 denotes a warm air fan disposed at the lower part of the pedestal 2, and its outlet 4a faces the hole 3 of the pedestal 2.

Reference numeral 5 denotes a heat exchanger disposed on the upper part of the pedestal 2. A combustion part 6 is built into the lower part of the heat exchanger 5, and a combustion fan 7 is integrally provided on the side thereof.

An ignition heater 8 is provided in front of the combustion section of the heat exchanger 5, and a smoked material supply pipe 9 and a smoked material return pipe 10 are provided, respectively.

Reference numeral 11 denotes an outlet opening for blowing out warm air provided on the front plate 1a of the housing 1, and is shaped so as to face the heat exchanger 5.

The blow-off opening 11 is shaped so that its lower edge is located below the parts such as the ignition heater 8 and the pipes 9 and 10, as shown in FIG.

Also, as is clear from the figure, the lower end edge of this blowout opening 11 is bent inward 11a, so that the air from the warm air fan 4 is forced onto parts such as the ignition heater 8 as shown by arrow a. It's starting to hit the mark.

Therefore, according to the hot air heater having the above configuration, the functional parts such as the ignition heater 8 provided on the front side of the heat exchanger 5 are always cooled by the air from the hot air fan 4, and there is no risk of heat loss. It becomes less.

At the same time, if the outlet louver body 12 installed in the outlet opening 11 is removed, functional parts such as the ignition heater 8 can be seen through the opening 11, so there is no need to take the trouble of removing the front plate 1a. It will also be possible to inspect, repair, etc. the ignition starter 8, etc.

In particular, since the air outlet louver body 12 is installed in the air outlet opening 11 provided on the front plate 1a of the housing 1, its attachment point is only on the front side, and there is no attachment point on the side surface of the housing like the front plate 1a. This is effective because when there is an object on the side of the case, there is no need to move it to attach or detach it.

As described above, according to the present invention, the wind from the hot air fan always flows toward the functional component at the front of the heat exchanger through the bent piece provided at the lower edge of the blow-off opening, so that the heat of this functional component is reduced. The risk of damage is greatly reduced, and reliability is significantly improved.The above-mentioned blowout opening extends to the functional parts on the front of the heat exchanger, making it possible to inspect and repair the functional parts from this opening, making maintenance easier. It has practical value, such as being able to do it easily from the front.
