Description

[Detailed Description of the Invention] The present invention relates to a heating evaporation type humidifying device that is incorporated into a stove.

In conventional humidifiers of this type, an evaporating dish is placed on top of a heat exchanger installed inside the main body, and this evaporating dish is heated by combustion from a stove to boil the water inside, which is then heated by a blower. Cool air was sent in to lower the temperature of the steam, which was then released into the room from the steam outlet.

However, with this type of humidifier, if humidification continues,
Water scale gradually deposits inside the evaporating dish and the water becomes sticky.
When boiling, this foam rises and overflows to the outside through the cold air inlet, causing rust in various parts.

This invention was made to eliminate the above-mentioned drawbacks, and has heat receiving fins on the outer bottom surface of the evaporating dish placed on the top surface of the heat exchanger installed in the stove. In a humidifier that connects the cold air inlet of the evaporating dish and the blower, the heat receiving fins are heated by the combustion gas passing through the heat exchanger, which boils the water in the evaporating dish and generates steam. A cold air guide plate is installed in the cold air guide duct that partitions the inside of the duct into an upper and lower part, and a part of the cold air is sent toward the bottom of the evaporating dish, thereby suppressing the rise of boiling bubbles by cooling them. It is something.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 is a heat exchanger installed in a stove (not shown), 2 is an evaporation plate placed on the top surface of this heat exchanger 1, and has heat receiving fins 3 on the outer bottom surface. fin 3
faces into the heat exchanger 1.

4 is a cold air inlet provided on a part of the circumferential side of the evaporating dish 2;
5 is a cold air guide duct, the - side is connected to the cold air introduction port 4,
The other side is opened to the air passage of the blower 6.

A cold air guide plate 7 is installed inside the cold air introduction duct 5 and partitions the inside into an upper passage 8 and a lower passage 9, and a downwardly inclined part 10 is provided on the side of the cold air introduction port 4 to form a lower passage 9. The cold air sent into the evaporating dish 2 through the cold air inlet 4 is guided to the bottom side of the evaporating dish 2.

Note that 11 is water stored in the evaporation dish 2.

The present invention has the above configuration, and when the stove is operated, the heat receiving fins 3 are heated by the combustion gas passing through the heat exchanger 1, and the water in the evaporating dish 2 is uniformly and quickly vaporized. occurs.

At the same time, the cold air sent from the blower 6 is sent into the evaporating dish 2 through the upper passage 8 and lower passage 7 of the cold air guide duct 5, mixes with high-temperature steam, lowers the temperature, and is discharged into the room.

At this time, the evaporating plate 2 is passed through the lower passage 9 of the cold air guide duct 5.
Since the cold air sent inside is blown toward the bottom side of the evaporating dish 2 as shown by the arrow, water scale may precipitate and accumulate inside the evaporating dish 2, and boiling bubbles will be generated due to the sticky water. Even if it rises, it will be cooled, and the rise will be suppressed, and the cold air introduction port 4
There is no overflow to the outside through.

As explained above, in this invention, a part of the cold air sent from the blower into the evaporating dish is sent toward the bottom of the evaporating dish, so that the water in the evaporating dish can be boiled uniformly and in a short time. This is mixed with cold air from a blower to lower the temperature and released into the room in a safe manner, and even if boiling bubbles due to water scale etc. occur as the water boils, the rise of the bubbles is suppressed. Unlike the conventional method, there is no overflow to the outside through the cold air inlet, and there is an advantage that rust etc. do not occur around the evaporating dish.

[Brief explanation of drawings]

The drawing shows a longitudinal sectional view of the humidifying device of the present invention. In the figure, 2 is an evaporation plate, 4 is a cold air inlet, 5 is a cold air guide duct, 7 is a cold air guide plate, and 9 is a lower passage.
