Description

[Detailed Description of the Invention] The present invention relates to a hot air heater that allows water to be easily supplied from the outside to a humidifying tray installed inside a casing.

Conventionally, in this type of warm air heater, the humidifying tray is installed inside the casing, so the capacity of the humidifying tray is relatively small due to the dimensional constraints of the installed part, so the user has to Water had to be supplied at relatively short intervals, which was very inconvenient for the user.

In addition, to supply water to the humidifying dish, since the humidifying dish is installed in a position where the humidifying plate inside the casing maximizes the humidifying effect, it is necessary to open the front panel, which is usually removably attached. Not only is this troublesome for the person, but the amount of water in the humidifying dish cannot be seen from the outside, so even if the water in the humidifying dish runs out, water is often not refilled. I hated not being used.

The present invention seeks to eliminate these drawbacks and will be explained below with reference to the figures.

In the figure, an air filter 7 is provided between the legs 80 attached to the left and right sides of the bottom of the casing 1 to serve as an indoor air intake;
Indoor air drawn by the fan 6 is turned into warm air by the combustion cylinder 2 equipped with a heat exchanger (not shown), flows through the air duct formed by the air guide 3, and opens at the front of the upper part of the casing. It is blown out from 4.

As is clear from the figure, the humidifying plate 9 is a passage for warm air so that the hot air humidified by the blade U is decelerated by the humidifying plate 9 and becomes mild warm air in order to increase the humidifying effect. The upper end of the air duct part is made to protrude so that the wide surface directly collides with hot air, and the lower end is immersed in a humidifying dish 10 provided at the lower part of the air duct inside the casing.

The humidifying plate is made of glass fibers that have a strong capillary effect, so the humidifying water rises up the humidifying plate due to the capillary effect.
It evaporates at its upper end exposed to the air duct section, which is the hot air passageway, producing a humidifying effect on the hot air.

5 is a front panel that is detachably attached to the casing.

Reference numeral 12 denotes a water pouring tray provided at the top of the casing, which is fully or partially open to the outside and is provided with a lid (not shown) for the opening that can be easily attached and detached as needed.

This water pouring tray has a humidifying tray 10 and a ball tap 1 for liquid level control.
They are connected by a water supply pipe 13 equipped with a water supply amount adjustment device such as No. 1, and the humidifying water in the water pouring tray is supplied to the humidifying dish according to the amount of water in the humidifying dish by a ball tap via the water supply pipe.

The amount of water in the humidifying tray decreases over time due to the humidification of hot air, but when the amount of water set by the ball tap is reached, it is replenished from the ball tap, and conversely, if the amount of water in the humidifying tray increases, the float of the preset ball tap When the water stop level is reached, the water supply is stopped.

Therefore, according to the hot air heater of the present invention, when checking the amount of humidifying water or when supplying water, the front panel can be opened to inspect the humidifying tray.
There is no need to directly supply water to the humidifying dish, just check the water level using the water injector 12, and then supply water.There is no need for the troublesome removal and attachment of the front panel as in the past, and the user can check the water level and supply water for humidification. Easier to implement.

In addition, the capacity of the water injector can be made relatively large because there are fewer dimensional restrictions depending on the installation location than in the case of a humidifying dish.
In addition to the capacity of the conventional humidifying dish itself, it can hold a large amount of humidifying water, so the frequency of water supply is reduced, requiring less effort on the part of the user, and the humidifying effect is always maintained during heating. can be expected.

Furthermore, since the water injector is located at the upper part of the hot air passage, there is an advantage that during heating, the temperature of the water injector itself increases and evaporates directly from the water injector itself, resulting in an increase in the amount of humidification.

In addition, according to this idea, the humidifying plate is arranged so that the wide surface directly collides with the hot air, so the warm air is decelerated by the humidifying plate and becomes mild warm air, providing comfortable heating. can be done.
