Description

[Detailed Description of the Invention] The present invention relates to a humidifying device incorporated in a hot air heater.

In hot air heaters with built-in humidifiers, the steam generated from the humidifier causes rust on the heat exchanger, significantly reducing its durability.

The present invention has been made to eliminate the above-mentioned drawbacks, and one embodiment thereof will be described below with reference to the accompanying drawings.

In the figure, 1 is the cabinet of the warm air heater, 2 is the combustion tube installed inside this cabinet 1, and the burner 3 is located at the bottom.
The auxiliary heat exchanger 4 is connected to the upper part.

5 is an air supply passage connecting the burner 3 and the outdoors, and a combustion blower 6 is provided in the middle.

Reference numeral 7 denotes an exhaust passage that connects the auxiliary heat exchanger 4 and the outdoors, and exhausts the exhaust gas after combustion to the outdoors (7).

Reference numeral 8 denotes a hot air blower, which is attached to the back of the cabinet 1 and blows hot air that has undergone heat exchange with the combustion tube 2 and the auxiliary heat exchanger 4 to the front of the cabinet 17'.

Reference numeral 10 denotes a humidifying plate placed on the upper surface of the auxiliary heat exchanger 4, which has heat receiving fins 11 connected to the auxiliary heat exchanger 4 in the garden, and has a cold air inlet 12 on the side substantially facing the hot air blower 8. It is set up.

13 is a water supply tank that supplies water to the humidifier 10, and a water supply pipe 1
4 to the humidifying tray 10.

Reference numeral 15 denotes a cold air introduction guide attached to the outer wall of the humidifying tray 10 above the cold air introduction port 12, and a downwardly sloping part 16 is provided on the other side, and a part of the air sent from the hot air blower 8 is introduced into the cold air. It is sent to the humidifying tray 10 through the opening 12.

Reference numeral 17 indicates that the water receptacle is a dish, and the inclined portion 1 of the cold air introduction guide]5 is
6 and placed on a placing piece 18 provided on the outer wall of the humidifying tray 10.

Reference numeral 19 denotes a steam outlet provided on the upper surface of the cabinet 1, which is connected to the upper opening of the humidifying tray 10 via a sealing backing 20, and a steam outlet 1]21 is provided in a part thereof.

The present invention has the above configuration, and when the heater is operated, the heat receiving fins 11 are heated by the exhaust gas passing through the auxiliary heat exchanger 4, thereby boiling the water in the humidifying tray 10 and generating steam. Air from the hot air blower 8 is sent to this steam through the cold air introduction guide 15 and the cold air introduction port 12, and the steam is blown out from the steam outlet 21 while being cooled.

At this time, a part of the steam flows back to the lower surface of the cold air introduction guide 15 through the cold air introduction port 12, but the steam comes into contact with the lower surface of the cold air introduction guide 15 and becomes fine water droplets at the inclined part 16 of the cold air introduction guide 15. flows to

Then, the water droplets that flowed in naturally dry over time, and the remaining water drips from the lower end of the inclined portion 16 into the dish 10.
It drips into the water, collects therein, and prevents it from flowing into other parts, thereby preventing the occurrence of rust, etc.

As described above, the present invention provides a cold air inlet in the side wall of a humidifying tray placed on the heat exchanger of a heater, and introduces air from a hot air blower into the humidifying tray through this inlet to humidify the humidifying tray. In this method, a cold air introduction guide is provided at the upper part of the outside of the intake port, and a water receptacle is provided at the bottom of this guide, so that the heat exchanger and other functional parts do not rust due to humidification. It has the advantage of being able to withstand long-term use.

[Brief explanation of the drawing]

The drawing shows a longitudinal sectional view of the invention. In the figure, 8 is a warm air blower, 10 is a humidifying tray, 12 is a cold air inlet, 15 is a cold air introduction guide, 16 is a sloped part, 1
7 is a dish for water.
