Description

[Detailed Description of the Invention] The present invention relates to a humidifying device for a hot-air heater, and relates to a structure for regulating the blowing direction of steam generated in an evaporator.

In conventional warm air heaters incorporating this type of humidifier, the steam outlet is fixed in a fixed direction, and depending on where the heater is installed, the direction of the steam outlet may be inappropriate, making installation impossible. It may disappear.

For this reason, a structure in which the outlet body is installed horizontally so as to be able to change the blowing direction of the steam can be considered.
This type of hot air heater is generally installed close to a wall, and there is a risk that the steam outlet may be directed toward the wall.
In addition, in a structure in which steam is blown out by the airflow generated by a convection fan, the convection fan takes in air from the air supply opening formed at the back of the case body, so the steam blown toward the wall surface is returned to the inside of the case body. There is a risk of being inhaled.

The present invention was developed in view of the above-mentioned drawbacks, and it is possible to attach the outlet body forming the steam outlet so that it can rotate freely in the horizontal direction, and to restrict the range of rotation, so that the outlet can be set toward the back. To provide a humidifying device for a hot air heater that prevents the heating of hot air from occurring.

Next, the structure of an embodiment of the present invention will be explained with reference to the drawings.

Next, the operation of this embodiment will be explained.

Fuel, which has been replaced with air from the fuel tank 14 and is supplied to the fuel receiver 11 while maintaining a predetermined liquid level, is supplied to the burner 9 via the fuel amount regulator 13.

On the other hand, air sucked from the intake port 3 by the air supply fan 6 rotated by the electric motor 5 is supplied to the burner 9, and the fuel supplied to the burner 9 is vaporized by ignition, and the vaporized fuel and air are mixed. The gas is combusted in the combustion chamber 22, and the exhaust gas is introduced into the heat exchanger 24.
4 and is discharged from an exhaust port 35 by an exhaust fan 36 which is rotated by an electric motor 5.

On the other hand, the convection fan 55 rotates due to the drive of the electric motor 56.
The air taken in from the intake port 3 is transferred to the combustion chamber 22 and the heat exchanger 2.
4, heat is exchanged, and the hot air is blown into the room from the hot air outlet 57.

The exhaust gas from the combustion chamber 22 heats the heat conduction plate 42 provided in the heat exchanger 24 directly above the combustion chamber 22, and the evaporation plate 3 of the evaporator 37 is in contact with the heat conduction plate 42.
8 is also heated, and the water in the evaporating dish 38 is heated and boiled and evaporated to 100°C.

On the other hand, a part of the wind generated by the convection fan 55 is supplied through the air duct 53 into the evaporating dish cover 39 of the evaporator 37, and the vapor vaporized in the evaporating dish 38 is mixed with the air flowing into the evaporator 37. Then, the temperature of the steam is lowered, and the temperature of the steam becomes visible, and the steam passes through the steam passage 70 of the steam duct 63, is regulated by the air regulating plate 75 formed on the blow-off lower part 7 of the blow-off port body 74, and is blown into the room. Humidify the room.

The high-temperature steam generated in the evaporating dish 38 is then throttled through the steam vent 68 of the steam duct 63, and a detour steam path 70 leads to the blow-off hole 69 located at a position offset from above the steam vent 68. The steam is mixed with the air blown from the convection fan 55 and blown out from the blowout lower 7, so the temperature is lowered and the steam is not blown out directly at a high temperature.

Further, when the water in the evaporation tray 38 evaporates and the water level drops, water is supplied from the water tray 48 and is always maintained at a constant position.

When the water level in the water tray 48 becomes low, the on-off valve 51 of the water tank 50 is pressed by the operating pin 49.
Water is replaced with air from the opened water inlet 52 and drips into the water tray 48, and when the water level in the water tray 48 reaches the position of the water inlet 52, the water in the water tank 50 can be replaced with air. There is no water dripping, and the water level in the water tray 48 is kept constant.

Further, inspection and cleaning of the humidifying device can be carried out by opening the cover plate 71 and removing the steam duct 63 and evaporator 37.

In addition, when adjusting the blowing direction of steam, the blowing outlet body 7
4, the outlet body 74 is rotated by the engagement of its hook 80 with the periphery of the fitting hole 76a of the mounting frame 76, and in the range where the outlet lower 7 faces the back side, the regulating flange 81 is rotated. both edges 8
1 a is locked by the locking protrusion 82, and the rotation of the blowout [] body is restricted, and the blowout lower 7 does not face the back, so steam is not sprayed toward the wall and the case is closed. Steam is not sucked into the intake port on the back of the body 2.

Depending on where the warm air heater is installed, if the blower lower 7 is directed toward the rear side, the locking protrusion 82 may be bent downward to prevent it from engaging with the regulating ridge 81 of the blower outlet body 74. Make it.

According to the present invention, a regulating protrusion is provided at the lower end of the outlet body that is engaged with a retaining protrusion that protrudes from the case body and restricts the rotation range, so that the blowing direction of steam can be adjusted as desired.
Further, it is possible to prevent the blow-off port from being directed toward the back of the case body, and it is possible to prevent steam from being sucked into the case body by the air flow sucked by the convection fan from the back side of the case body.
