Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a humidifying device installed in a warm air heater.

[0002]

2. Description of the Related Art Conventional forced air supply / exhaust type warm air heaters are disclosed, for example, in Japanese Utility Model Publication Nos. 54-170663, 56-148527, 57-109427 and 57-109427. 60-125434, JP 61-3
The configurations are as disclosed in Japanese Patent No. 338, respectively. That is, a warm air passage having one end connected to the indoor air inlet and the other end connected to the warm air outlet is formed in the main body, and a convection blower, a closed combustion combustion device, and a heat exchanger are arranged in this warm air passage. It is set up. In the combustion device, combustion air is supplied from the outside by an air supply system, and combustion waste gas is exhausted to the outside by an exhaust system connected to the rear end of the heat exchanger. The convection blower forms a flow of indoor air in the warm air passage, and causes the indoor air sucked from the indoor air suction port to come into contact with the heat exchanger and blow out as warm air from the warm air outlet to the room. And, as shown in the above-mentioned publication, many of this kind of heaters incorporate a humidifying device in order to improve the indoor heating environment. As the humidifier, for example, an evaporation dish for storing water is provided on the bottom side of the main body, and a part of warm air is introduced into the evaporation dish by an air duct.

The conventional hot-air heater having the above structure can obtain a clean heating atmosphere without polluting the indoor air with the combustion waste gas, and the one equipped with the humidifying device evaporates a part of the warm air to the evaporating dish. The water can be evaporated, and the humidified air can be blown out into the room together with the warm air to create a humidified atmosphere in the room.

[0004]

In the conventional humidifying apparatus as described above, it is troublesome to supply water to the humidifying tray frequently, so that the humidifying tray is replenished with water by a cartridge tank having a water supply portion with a valve. The ones that are designed to be used are also in practical use. In this type, the evaporation tray and the cartridge tank are compact and thin so that the heater itself does not become large due to the storage space of the cartridge tank. Therefore, if the flat surface is not maintained during installation, water may accumulate in the water supply portion of the cartridge tank, and water may not be smoothly supplied to the evaporation dish.

An object of the present invention is to provide a humidifying device which can be accommodated in a limited space on the bottom side of a warm air heater and which can smoothly supply water to an evaporation tray.

[0006]

A humidifying device for a warm air heater according to the present invention is provided on the bottom side of the main body of the warm air heater, and a part of the warm air is supplied by an air duct. The bottom part is provided with an evaporating dish having a projecting part, and a projecting part of the evaporating dish is provided with a water supply part with a valve protruding to the bottom part on one side, and is provided with a cartridge tank which is a flat closed container capable of supplying water. A water guide groove extending from the protruding portion to the evaporation side facing the air duct is formed on the bottom of the evaporation dish.

[0007]

In the humidifying device for a warm air heater according to the present invention, the water level of the cartridge tank is lower than that of the water supply unit even if the water supply unit side of the cartridge tank is lowered. If it goes down, water will be replenished from the cartridge tank, and water will be collected in the entire evaporation dish by the water guiding groove.

1 is a side sectional view of a warm air heater showing an embodiment of the present invention. This warm air heater is a forced air supply / exhaust type floor installation type equipped with a humidifying device, and functional components related to heating are basically the same as those of the conventional type. That is, in the main body 1, a warm air passage is formed, one end of which is connected to the indoor air intake port 2 provided on the back surface of the main body 1 and the other end of which is connected to a warm air outlet 3 provided on the lower front surface of the main body 1. ,
A convection blower 4, a closed combustion type combustion device 5 and a heat exchanger 6 are arranged in this warm air passage. In the combustion device 5, combustion air is supplied from the outside by an air supply system (not shown), and combustion waste gas is exhausted to the outside by an exhaust system (not shown) connected to the rear end of the heat exchanger 6. The convection blower 4 forms a flow of indoor air in the warm air passage, contacts the indoor air sucked from the indoor air suction port 2 with the heat exchanger 6, and blows it out from the warm air outlet 3 into the room as warm air. On the bottom side of the main body 1, a humidifying device for forming a humidified hot air by applying a part of the hot air after heat exchange to the water accumulated in the evaporation tray 8 by an air duct 7 formed of a steel plate in a rectangular tube shape is configured. ing.

As shown in FIG. 2, the humidifying device is constructed as an evaporation tray 8 mounted on the bottom side of the main body 1 so that it can be inserted and removed from the front surface, and a flat closed container for automatically replenishing the evaporation tray 8 with water. The cartridge tank 9 and the air duct 7 that guides a part of the warm air to the evaporation dish 8, the outside of the evaporation dish 8 and the air duct 7 is surrounded by the partition plate 10, and the lower side of the evaporation dish 8 is received. It is separated from the installation floor surface by the plate 11 and the bottom plate 12.

As shown in FIG. 3, the evaporation tray 8 is a shallow open container surface-treated with enamel, and the evaporation side of the air duct 7 facing the open end and the cartridge tank 9 are covered.
It consists of the water supply side and the water supply side. A projecting portion 13 that bulges in a spherical shape is formed on the bottom portion on the water supply side, and a water guiding groove 14 extending from the projection portion 13 and bifurcated is formed on the bottom portion on the evaporation side. At the bottom of the evaporation dish 8, rib-shaped legs 15 are bulged to the left and right for mounting on the receiving plate 11. The opening on the water supply side of the evaporation dish 8 is closed by a cover 16 that is detachably attached. The cover 16 is composed of an upper lid part 17 for closing the upper part on the water supply side and an apron part 18 in the form of a front drop separating the water supply side and the evaporation side.
A guide hole 19 is formed at a position corresponding to the protruding portion 13.

In the cartridge tank 9, a water supply section 20 with a valve projects downwardly toward one side of the bottom, and when the end of the water supply section 20 contacts the projecting section 13 of the evaporation tray 8, the valve is opened and the water supply is possible. Therefore, it is mounted on the bottom of the main body 1 beside the evaporation dish 8 in parallel with the evaporation dish 8 from the front side of the main body 1.

The warm air heater having the above-mentioned structure can be heated by warm air as is well known, and a humidifying atmosphere can be obtained by a humidifying device. The humidifier operates by setting the evaporation dish 8 and the cartridge tank 9 containing water. The cartridge tank 9 can be mounted properly by inserting the water supply portion 20 into the guide hole 19 of the cover 16 provided on the water supply side of the evaporation tray 8 so that the water supply portion 20 automatically contacts the protruding portion 13 of the evaporation tray 8. It can be easily performed even if it is in a position and can not be seen. When the water supply unit 20 hits the protruding portion 13, the built-in valve opens and water is supplied from the cartridge tank 9 to the evaporation tray 8 to a water level at which the water supply unit 20 is hidden, and the water guided to the evaporation side by the water guiding groove 14 is changed to the evaporation side. At, the air is evaporated by the hot air from the air duct 7 to humidify the hot air, and the hot air is blown out from the hot air outlet 3 as humidified hot air into the room. Evaporating dish 8 consumed by evaporation
The water is replenished from the cartridge tank 9 every time the liquid level falls below a predetermined level. The warm air for humidification is supplied to the side of the evaporation tray 8 which receives the water supply section 20 and the apron section 1 of the cover 16.
8 and the upper lid 17 do not leak to the outside.
Since the evaporation tray 8 is shallow, if the water supply side is slightly lowered, water may not be replenished even if water is accumulated in the water supply part 20 and the evaporation side is depleted. If the water level of the water guiding groove 14 is lowered, the water supply portion 20 is moved above the water level, so that water is replenished and thin water is supplied to the whole area of the evaporation tray 8 by the water guiding groove 14.

[0013]

As is apparent from the above description of the embodiments, according to the present invention, even if the water supply side of the cartridge tank is lowered, water may be collected on the water supply side. , If the water level is lower than the water supply part, air can enter the cartridge tank from the water guiding groove, so water is replenished, and the water guiding groove collects water over the entire evaporation tray, so that water supply for humidification is a thin bottom. It will be done smoothly even on the evaporation dish.
