2. Description of the Related Art Conventional humidifiers are generally equipped with a heating element and an ultrasonic vibrator inside and vaporize water by this energy. Further, there is a method in which the lower end of the vaporization wick is immersed in water of a basin containing water, and the water sucked up by the vaporization wick is naturally evaporated into the air to heat it.

[0003]

The one using an electric heating element as energy for evaporating water has a very high energy cost, the maintenance cost is required to obtain a large amount of water vapor, and the one using an ultrasonic transducer is very expensive. The energy efficiency is better than that of the electric heating element, but the amount of steam generated is limited. In addition, the heat source of the heat source is the heat generated from the combustor, which constitutes a humidifier integrally with the combustor, which is advantageous in terms of energy cost. There is a limit to the space and shape for mounting. Further, since the one using the vaporization wick does not artificially add energy from the outside, the energy cost is the lowest, but a large amount of evaporation cannot be expected.

Therefore, in order to inexpensively obtain a large amount of humidification in a desired place in advance, none of the conventional humidifiers can satisfy the requirements, and the electricity cost is too high or too large. Was to have.

By the way, the only conventional method that can obtain a large amount of humidification with low energy cost is to construct a humidifier by incorporating it into a combustor. In this method, a combustor with a humidifier is installed at a place desired by the operator. In some cases, it could not be installed, and it was often installed and used in an unsatisfactory place.

[0006]

The present invention relates to the structure of a humidifier which introduces warm air generated from a warm air generator using various heat sources to humidify it most efficiently. An upper surface cover that forms a horizontally long opening 2, a partition plate 3 is provided at the edge of the opening 2 so as to look into the bottom surface of the water tank 1, and an air circulation space 4a is formed above the opening 2. 4, a windshield 5 is attached to one end of the top cover 4, and the top cover 4 near the windshield 5 blows warm air from a warm air generator toward the inside of the water tank 1. An inlet 6 is provided, and the upper portion of the opening 2 excluding the vicinity of the warm air inlet 6 is seen through the air circulation space 4a, and the lower portion is formed of the water tank 1.
The vaporizing element 7 submerged in the water is attached, and the outlet 8 of the humidified air is located on the opposite side of the upper surface cover 4 where the windshield plate 5 is not provided. The warm air blown from the warm air inlet 6 is It hits the water surface of the water tank 1 and is blown out as humidified air containing a large amount of water vapor while being guided by the partition plate 3 and reaching the air outlet 8 along the water surface.

Further, by arranging a plurality of flat plate-shaped vaporizing elements 7 in parallel in the longitudinal direction of the horizontally long opening 2, the water surface and the vaporizing element 7 are surely guided while the hot air reaching the outlet 8 is surely guided. Humidified air is efficiently obtained from both.

Further, a large number of heat radiating fins 4b are provided on the outer surface of the upper surface cover 4 provided above the horizontally elongated opening 2 so that the upper surface cover 4 functions as a radiator.

Further, a bent edge 3a is formed on the upper part of the partition plate 3 in the longitudinal direction of the horizontally long opening 2, the upper cover 4 is attached to the bent edge 3a, and the lower part of the partition plate 3 is the water tank 1.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the embodiments shown in the drawings. 1 is a water tank formed by blow molding or the like, 2 is a horizontally long opening provided on the upper surface of the water tank 1, and 3 is a water tank from the vicinity of the opening edge. 1 is a partition plate looking into the bottom surface, and the partition plate 3 has a function of inducing warm air as described later,
It is provided along at least the opening edge in the longitudinal direction of the horizontally long opening 2. Further, when a partition plate is provided along the opening edge of the opening 2 in the short direction, the rectangular frame may be formed integrally with the partition plate in the long direction.

Reference numeral 4 denotes an upper surface cover which forms an air circulation space 4a above the opening 2, 5 is a windshield plate which is attached to one end of the upper surface cover 4 to prevent wind from flowing out from the opening 2, and 8 is an upper surface cover. 4, an air outlet attached to the other end of 4, a hot air outlet provided on the top cover 4 near the windshield 5, and a hot air duct 6a connecting the hot air generator (not shown) to the hot air outlet 6. Yes, the hot air blown out from the hot air outlet 6 is the direct water tank 1
It is sprayed on the water surface inside.

Reference numeral 3a denotes a bent edge formed on an upper portion of the partition plate 3 provided along the opening edge of the opening 2 in the longitudinal direction, and a guide 4c fitted to the bent edge 3a is attached to the upper surface cover 4. The upper cover 4 is positioned above the opening 2 by sliding the guide 4c while fitting the guide 4c on the bent edge 3a.

The lower end of the partition plate 3 reaches the bottom surface of the water tank 1, the weight of the top cover 4 is directly applied to the partition plate 3 via the bent edge 3a, and the weight including the partition plate 3 is equal to that of the water. It is received on the bottom of the tank 1. For this reason, the stability as a humidifier becomes very good, and the hot air from the hot air generator is blown into the top cover 4 so that the opening 2 of the water tank 1 is opened.
Even if the temperature rises in the vicinity, the weight of the top cover 4 is not applied to the opening 2, so that even the blow-molded water tank 1 is hardly deformed, and the durability of the water tank 1 can be improved.

Numeral 7 is a vaporizing element located in the opening 2 except for the vicinity of the hot air outlet 6 and having an easily held shape such as a string, a strip or a flat plate. Nozomi, the lower part is installed so as to be submerged in the water of the water tank 1, and the warm air blown from the warm air outlet 6 toward the water surface of the water tank 1 is guided to the partition plate 3 toward the outlet 8. When flowing, it vaporizes the water sucked up by the vaporization element 7 and obtains humidified air.

Reference numeral 9 denotes a connecting shaft which is provided along the longitudinal edge of the opening 2 and holds the space between the two partition plates 3. The end of the connecting shaft 9 is fixed to the partition plate 3. . The vaporization element 7 of the embodiment shown in the figure is formed in a flat plate shape extending in the longitudinal direction of the opening 2, and a plurality of sheets are held together by penetrating the connecting shaft 9, and the vaporizing element 7 is attached to the connecting shaft 9. A partition plate 9a for holding the interval is attached, and a plurality of vaporization elements 7 are attached at predetermined positions. Therefore, the vaporizing element 7 does not interfere with the flow of warm air reaching the air outlet 8 along the water surface, and the warm air smoothly flows through the interval between the vaporizing elements 7, so that water can be discharged from both the vaporizing element 7 and the water surface. A large amount of humidified air could be obtained by evaporation.

On the other hand, in order to efficiently obtain the humidified air, the temperature of the hot air supplied from the hot air generator may be increased, but the air circulation interval 4a is a hot air flow path and the temperature of the upper cover 4 rises. And dangerous. According to the present invention, since the heat radiation fins 4a are attached to the upper surface cover 4, the heat of the upper surface cover 4 is quickly dissipated by the action of the heat radiation fins 4a, and the tip portion of the heat radiation fins 4a of the upper surface cover 4 which is easily touched by the hands has a lower temperature. Therefore, it can be safely used even when using high temperature hot air.

[0019]

As described above, according to the present invention, the partition plate 3 in the water tank 1 corresponding to the horizontally elongated opening 2 and the top cover 4 serve to spray the water from one end of the top cover 4 onto the water surface. The warm air flows along the water surface toward the other air outlet 8 of the top cover 4, and the vaporization element 7 is attached to the openings other than the vicinity of the hot air blowing port 6 and the hot air flowing along the water surface. Since it passes between the vaporization elements 7 and reaches the outlet, the water in the water tank 1 is efficiently vaporized, and a large amount of humidified air can be obtained.

Further, in such a humidifier, the warm air obtained by the warm air generator, which is a heat source, is blown into the humidifier from the warm air blowing port 6, so that the humidifier and the warm air generator are different from each other. It doesn't have to be integrated, and both can be set at any place,
It has improved usability, and by appropriately selecting the capacity of the hot air generator to be combined, it is possible to put it into practical use from large ones for agriculture and gardening and industrial use to small ones for home use. The excellent humidifier structure with wide application range has been completed.

On the other hand, regarding the structure of the humidifier, since the vaporizing element 7 is formed in a flat plate shape facing the longitudinal direction of the opening 2 and a plurality of vaporizing elements are arranged side by side, the vaporizing element 7 resists the resistance of the warm air toward the outlet 8. It is difficult for the hot air to flow and the hot air flows along the water surface of the water tank 1, and the water is evaporated using the entire water surface and the vaporization element 7 protruding from the water surface, so that the humidification efficiency is improved.

Further, since the air circulation interval 4a covered with the upper cover 4 serves as a hot air flow path, the warm air heats the upper cover 4 in the same manner as the water surface and the vaporization element 7, and means for improving the humidification efficiency. As a result, even if the warm air temperature is raised, the heat radiation fins 4b are attached to the outer surface of the top cover 4, and the heat radiation from the heat radiation fins 4b allows the top cover 4 to maintain a low temperature. I was able to keep it.

Further, since the lower portion of the partition plate 3 reaches the bottom surface of the water tank 1, and the upper surface cover 4 is attached to the bent edge 3a of the upper portion of the partition plate 3 in the longitudinal direction, the partition plate 3, the upper surface cover 4 and the vaporization are formed. Since the weight of the element 7 is directly applied to the bottom surface of the underwater water tank 1 and no force is applied only to the upper portion of the water tank 1, there is a risk of deformation even if the strength of the water tank 1 deteriorates due to the heat of warm air. However, the durability of the humidifier was increased and the stability of the humidifier was improved.
