  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of a humidifying device of the invention will be described with reference to the accompanying drawings.

Embodiment 1
The humidifier of Embodiment 1 is demonstrated using FIG.1 and FIG.2. FIG. 1 is a front sectional view showing an internal configuration of a humidifying device according to Embodiment 1 of the present invention. FIG. 2 is a side cross-sectional view showing the internal configuration of the humidifying device of FIG.

  In the front view of FIG. 1, a water supply tank 10 is disposed on the inner right side of the main body 1 that is a casing, and the water tank unit 3 is located with respect to the heating dish 11 disposed near the bottom of the inner left side of the main body 1. It is comprised so that water may be supplied through. The position of the water surface 13 on the heating pan 11 is always kept constant by supplying water from the water tank 3 and the water supply tank 10.

  As shown in FIGS. 1 and 2, an infrared light bulb 20 in which a heating element 22 as a heating means is incorporated is provided on the top of the heating dish 11. In addition, a heat absorbing body 23 that is in the shape of a saucer and opens upward is provided above the heating dish 11 and below the infrared light bulb 20. The endothermic body 23 has water absorption, and a part of the endothermic body 23 is in contact with the water surface 13 of the heating pan 11 and is in a flooded state. Further, a heat collecting plate 21 which is a reflecting plate is disposed on the upper portion of the infrared light bulb 20. The heat rays radiated from the heating element 22 of the infrared light bulb 20 are reflected by the heat collecting plate 21 to heat the heat absorbing element 23 in a water absorbing state. In this way, the heat absorbing body 23 is heated by the radiant heat from the heating element 22, and steam is emitted from the heat absorbing body 23 that has submerged in the water surface 13 at the top of the heating dish 11 and absorbed water.

  In the humidifying device of the first embodiment, a blower device 6 composed of a motor 9 and a fan 8 is provided on the upper part of the heat absorber 23, and air outside the device is taken in from a lower suction port 5 provided in the main body 1. The gas is discharged from the outlet 7 through the vaporization filter 2. Therefore, the steam generated in the heat absorbing body 23 is combined with the air that has passed through the vaporization filter 2 by the blower 6, and is released as humidified air from the outlet 7 through the air passage 4.

  In the humidifying device of the first embodiment configured and operating as described above, the heat collecting plate 21 that is a reflecting plate reflects the upward radiant heat emitted from the heating element 22 in the infrared light bulb 20. A parabolic cross section or a curved cross section capable of uniformly radiating the entire endothermic body 23 on the water surface 13. Therefore, when the heat absorber 23 is not provided, the heat collecting plate 21 has a shape that uniformly reflects the heat from the heat generator 22 and heats the water surface 13 on the heating dish 11 in the downward direction. The material of the heat collecting plate 21 is preferably a metal having high reflectivity such as aluminum, aluminum alloy, and stainless steel.

  The heat absorbing body 23 that is heated by the heating element 22 of the infrared light bulb 20 and has a water absorption property has a shape that can uniformly absorb the heat radiation from the heating element 22 and the heat collecting plate 21, and the water surface 13 on the heating dish 11. A wide contact area is preferable. For example, the shape is a saucer-like shape with an opening on the top or a shape with a concave on the top. In Embodiment 1, although the endothermic body 23 showed the structure arrange | positioned in the state in which the water surface 13 on the heating pan 11 was partially immersed, the endothermic body 23 was arrange | positioned under the water surface 13, The structure which receives the thermal radiation from the infrared light bulb 20 may be sufficient. The heat absorber 23 can be made of an aggregate of fibers containing glass fibers and carbon, or a porous body containing glass and carbon, thereby enhancing water absorption and heat absorption. Moreover, it cannot be overemphasized that the endothermic effect can further be heightened by making the heat-absorbing body 23 black, and also making the heating dish inner surface black.

Further, as the heating element 22 incorporated in the infrared light bulb 20, it is possible to achieve the effects of the present invention even if a known heating element is used. It is preferable to generate more water vapor by efficiently collecting and heating the water surface 13 on the surface 11. In order to obtain this effect, it is preferable to use a heating element that can efficiently radiate a water absorption region of 2 to 3 μm. For example, a carbon-based heating element that includes a carbon-based material and is formed by firing is an example. This carbon-based heating element has a high emissivity in the wavelength region where the heating effect is present, and since the emissivity is as high as about 0.85 in the water absorption wavelength region of 2 to 3 μm, it can be efficiently radiated. Thermal radiation is possible. By using such a carbon-based heating element, the water surface 13 on the heating pan 11 can be efficiently heated as compared with the consumed energy, and the heat absorbing element 23 in which water is absorbed is also efficiently obtained. Heating can promote the generation of water vapor.
In addition, as a material of the heating element 22, it is also possible to use a heating element composed of fibers, felts, or the like whose main component is a fiber having at least a carbon-based component, as a material similar to the above-described carbon-based heating element. is there.

  Hereinafter, a specific example of the heating element 22 which is a heating unit used in the humidifying device of the first embodiment will be described. However, the present invention is not limited to such a heating element 22 as long as it is a heating element capable of efficiently heating at least the radiation object as described above.

  The heating element 22 in the first embodiment is a solid carbon-based heating element formed by firing containing a carbon-based substance and a resistance adjusting substance, for example, a carbon-based substance formed into a long rod shape or plate shape, such as graphite. A mixture of a crystallized carbon base material added with a resistance adjusting substance of a nitrogen compound and amorphous carbon. The dimensions of the heating element 22 are, for example, a plate width W of 6 mm, a plate thickness T of 0.3 mm, and a length of 155 mm. The plate-shaped heating element 22 is desirably a wide shape in which the ratio between the plate thickness and the plate width is 1: 5 or more. By making the plate width W larger than the plate thickness T, the heat generated from the surface (wide surface) that defines the plate width W becomes larger than the heat emitted from the surface (narrow surface) that defines the plate thickness T. The directivity can be given to the radiant heat.

  Since the heating element 22 made of a carbon-based material has higher heat generation efficiency than energy consumption, the water surface 13 on the heating pan 11 can be heated with high efficiency. Further, for example, by setting the heating element temperature to 1200 ° C., the center value of the wavelength can be set to 2 μm, and a large amount of energy of 2 to 3 μm can be produced, thereby increasing the efficiency of the water absorption region. In addition, the heat absorption body 23 in which water is absorbed can be efficiently heated to promote the generation of water vapor. In the plate-shaped heating element 22, since heat radiation has directivity, by directing heat from the surface that defines the plate width W toward the water surface 13 on the heating pan 11, The heat absorber 23 can be efficiently heated to further promote the generation of water vapor.

  Next, a comparative experiment performed on the humidification characteristics by the respective heating methods in the humidifier of Embodiment 1 and the conventional humidifier will be described. As a heating method of the conventional humidifier, water was stored in a saucer-like container (length 250 mm, width 300 mm, depth 50 mm), and the sheathed heater was heated from below. FIG. 3 and FIG. 4 show the results of the comparative experiments and represent the respective humidification characteristics. In FIG. 3, the horizontal axis represents elapsed time [minutes], and the vertical axis represents steam generation amount [g]. In FIG. 4, the horizontal axis represents elapsed time [minutes] and the water temperature [° C.] in the vicinity of each heating means.

  3 and 4 showing the results of the comparative experiment, 500 cc of water is placed in a saucer-like container (length 250 mm, width 300 mm, depth 50 mm), and steam is generated by heating from below with a sheathed heater (300 W). The humidification characteristics of the example are indicated by C. In the following description, the configuration showing the humidification characteristic C is referred to as “conventional configuration C”.

  3 and 4, the experimental result curve indicated by B uses a solid carbon-based heating element formed by firing containing a carbon-based substance and a resistance adjusting substance as the heating element 22 of the infrared bulb 20, and The humidification characteristic when the heat collecting plate 21 which is a reflecting plate is provided in the upper part is shown. The heating element 22 used at this time has a plate shape with a plate width W of 6 mm, a plate thickness T of 0.3 mm, and a length of 155 mm, and the surface (wide surface) that defines the plate width W is a container (250 mm long, (Wide 300mm, depth 50mm). 500 cc of water was placed in this container and heated (300 W) from above by a plate-like carbon-based heating element. Therefore, in the humidification characteristic shown by the experimental result curve B, the water in the container is heated by the radiant heat from the plate-like carbon-based heating element 22 and the heat collecting plate 21. The temperature of the heating element 22 is about 1200 ° C. In the following description, the configuration showing the humidification characteristic B is referred to as “carbon-based heating element configuration B”.

  3 and 4, the experimental result curve indicated by A uses a solid carbon-based heating element formed by firing containing a carbon-based substance and a resistance adjusting substance as the heating element 22 of the infrared bulb 20, and The humidification characteristic when the heat collecting plate 21 which is a reflecting plate is provided in the upper part and the heat absorbing body 23 partially immersed in the water surface 13 is provided is shown. The heating element 22 used at this time has a plate shape with a plate width W of 6 mm, a plate thickness T of 0.3 mm, and a length of 155 mm, which is the same as the heating element 22 used in the experiment showing the above-described experimental result curve B. It is. Further, the surface (wide surface) that defines the plate width W of the heating element 22 faces the water surface in the container (longitudinal 250 mm, lateral 300 mm, depth 50 mm) and the direction in which the heat absorber 23 is disposed. 500 cc of water was put in the container, and the heat absorber 23 and the water in the container were heated (300 W) from above by the plate-like carbon-based heating element 22. Therefore, in the humidification characteristic indicated by the experimental result curve A, the water in the container is heated by the radiant heat from the plate-like carbon-based heating element 22 and the heat collecting plate 21 and the heat of the heat absorbing element 23. In the experiment showing the experimental result curve A, the endothermic body 23 composed of a carbon fiber layer (width 50 mm, length 150 mm, thickness 3 mm) was used. In the following description, the configuration showing the humidification characteristic A is referred to as “carbon-based heating element and endothermic configuration A”.

  As shown in FIG. 3, in each humidifier configuration, after 15 minutes of heating, the amount of water vapor generated was 33 g for “conventional configuration C”, 42 g for “carbon heating element configuration B”, and “carbon heating element and endothermic body” Configuration A ”was 51 g. Therefore, the configuration of the “carbon-based heating element and endothermic configuration A”, which is the configuration of the humidifying device according to the first embodiment of the present invention, has an excellent effect of obtaining more water vapor generation than the “conventional configuration C”. Play. In addition, it is clear from experiments that even a configuration of “carbon-based heating element configuration B”, which is a configuration in which the endothermic body 23 is not provided, can generate more water vapor than “conventional configuration C”.

As shown in FIG. 4, the water temperature in the vicinity of each heating means was 15 minutes after heating, and “conventional configuration C” generated 64 ° C. and “carbon heating element configuration B” generated 58 ° C., “carbon heating element and endotherm”. “Body structure A” is not so different from 66 ° C., but “carbon-based heating element and endothermic structure A” rapidly increased in temperature in the first few minutes, and the generation of water vapor is promoted in the initial state. In addition, when the tendency of a temperature rise is seen, when 15 minutes or more pass after a heating, it will be understood that the “conventional configuration C” has a gradient in which the water temperature further increases.
As is apparent from the above experimental results, the amount of water vapor generated is a state in which the configuration of Embodiment 1 according to the present invention (“carbon-based heating element and endothermic configuration A”) has a lower water temperature than the conventional configuration C. Can be confirmed.

  In the above experiment, in the conventional configuration C, generation of bubbles from the bottom surface was confirmed from 3 minutes after heating. On the other hand, in the configuration of Embodiment 1 according to the present invention (“carbon-based heating element and endothermic configuration A”), the generation of bubbles was not confirmed. Therefore, in the humidifying device according to Embodiment 1 of the present invention, it is possible to perform a quiet humidifying operation in which no bubble noise is generated.

  In the humidifier of the first embodiment, the heating element 22 in the infrared light bulb 20 has been described as an example of a plate shape. However, the shape of the heating element 22 is limited to such a shape. Instead, any shape that can efficiently heat the water surface 13 on the heating pan 11 by specifying the shape of the heat collecting plate 21 and the heat absorbing body 23 may be used.

In addition, the heating element in the humidifying device of the first embodiment is a rod-like shape that extends substantially linearly, but the end of the heat collecting plate 21 that is a reflecting plate is provided above both ends of the heating element. The configuration is not arranged. The purpose of this is to secure a space for efficiently and smoothly flowing water vapor generated on the water surface 13 on the heating pan 11 upward. By comprising in this way, the water vapor | steam which flows along the longitudinal direction on the lower surface of the heat collecting plate 21 can be efficiently flowed along with the rising airflow emitted from a heat generating body.
Further, in the humidifier of the first embodiment, the temperature of the air passage in the main body 1 is increased due to the heat generated from the heating element 22, and the temperature around the heat collecting plate 21 and the air passage is increased, so that it is difficult to condense and suppress generation of mold. It is a possible configuration.

  In FIG. 1, a temperature sensor 24 may be attached to the lower surface of the heating dish 11 facing the heating element 22 in the infrared light bulb 20 to detect the temperature of water in the heating dish 11. By comprising in this way, the temperature of the water in the heating pan 11 can be maintained constant, and water vapor | steam can be generated efficiently. Furthermore, when the water in the heating dish 11 runs out, the temperature of the heating dish 11 rises rapidly, so that it can be detected by the temperature sensor 24 and the humidifier can be turned off. . Furthermore, when the temperature sensor 24 fails, the device can be made safe by adopting a configuration in which the circuit is interrupted by the temperature fuse 26 provided in the vicinity of the temperature sensor 24.

Further, in the humidifying device of the first embodiment, as shown in FIG. 1, the humidity of the indoor air is measured by disposing a humidity sensor 25 in the vicinity of the lower suction port 5 of the main body 1 that is a housing. The indoor humidity can be automatically adjusted. By performing such automatic adjustment of room humidity, the user can spend comfortably without performing complicated humidity adjustment.
In the first embodiment, an example in which an infrared light bulb having a heating element 22 is used as the heating means is described. However, in the present invention, the water surface on the heating pan 11 is heated by a known heating means. However, it goes without saying that the effects of the present invention can be obtained.
