Description

DETAILED DESCRIPTION OF THE INVENTION <Technical Field> The present invention relates to a so-called infrared beam type humidifier that irradiates water with an infrared beam to generate water vapor and humidifies the water vapor.

<Prior art> Generally, as a method of humidification, a direct heating type in which water is directly heated by a heater in contact with water to generate water vapor, or water is blown off by a centrifugal force of a rotating cylinder to form a water Centrifugal type that generates water droplets by colliding with members and ultrasonic type that atomizes water with an ultrasonic vibrator are known, but especially for humidifying the space where infants and the elderly live. The above humidifiers are not very preferable.

For example, in the above-mentioned direct heating type, since the water is directly heated by the heater, the heated water is close to the boiling state, and very high temperature steam is blown out into the room. Therefore,
There is a risk of burns when exposed to this high-temperature steam, which is a high risk for infants and the elderly. In addition, since the heater and the electrode electrically connecting the heater are in direct contact with water, impurities of water gradually adhere to the heater and the electrode as heating and evaporation are performed, and the heating efficiency gradually decreases. Therefore, it is necessary to clean the heater and electrodes, but the structure of this part is complicated and it is very difficult for the user to clean.

In addition, the centrifugal type and ultrasonic type are water droplets that are humidified without heating them to heat them, so the temperature of the water droplets is room temperature and there is no risk of burns as with the heater heating type, Since the impurities contained in the particles are also blown out into the room together with the water droplets, these impurities may impair health. It has been reported that an ultrasonic humidifier causes allergic respiratory illness when bacteria that propagate in the stored water are blown out into the room together with atomized water. Centrifugal and ultrasonic humidifiers that blow out impurities contained in such water are not preferable for infants and the elderly who have weak immunity.

Therefore, an infrared beam type humidifier has been attracting attention recently. This infrared beam type humidifier uses an reflector to converge an infrared beam emitted from a heater or the like arranged at a predetermined distance from the stored water, and the converged infrared heater is used to store the stored water. The water vapor is generated by irradiating the. In this infrared beam type humidifier, the water irradiated by the infrared beam has a shallow water depth, and water evaporates near the surface of this shallow water depth. The temperature is low, so don't worry about burns. Moreover, since it is an evaporation type, it is hygienic without impurities being blown out together with steam, and is convenient as a humidifier in a space where infants and the elderly live.

However, even with this infrared beam type humidifier, the impurities do not blow out, so the impurities remain in the water, that is, inside the humidifier, and the inside of the humidifier becomes unsanitary. The inside needs to be cleaned. However, there is a problem that the portion where the water is stored is in a recessed position inside the humidifier and is difficult to clean because the shape is complicated. Further, there is a problem in that even if the cleaning is performed, it cannot be completely cleaned.

<Problems to be Solved by the Present Invention> It is an object of the present invention to make it possible to easily clean a portion storing water in an infrared beam type humidifier.

<Means for Solving the Problems> In order to solve the above-mentioned problems, the present invention has a bowl-shaped water tank portion opened to the upper surface side for storing water, and detachably mounted on the upper surface side of this water tank portion. A heating section for forming an air passage on the upper surface side of the water tank section and irradiating the water stored in the water tank section with an infrared beam so as to be located on the air passage side,
The main body is provided with an electric part such as a blower for discharging water vapor generated by heating by infrared irradiation to the outside of the device.

<Operation> With the above configuration, since the main body is equipped with the heating unit, the blower, and the control circuit, no electrical parts are mounted in the water tank that stores water, and the water tank is treated like a dish. be able to.

<Embodiment> An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional view of an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a water tank portion which is formed in a bowl shape and is open on the upper surface side. The water tank portion 1 is formed in a circular shape like a plate and has no electrical parts mounted thereon.

Reference numeral 2 denotes a main body that is detachably mounted on the upper surface side of the water tank portion 1. In the main body 2, a heating unit 3 that irradiates the water stored in the water tank unit 1 with an infrared beam, a blower 4 that guides water vapor generated by heating by infrared irradiation to the outside of the machine, and the heating unit 3 and a blower. And a control circuit (not shown) for controlling the control unit 4. The heating unit 3 includes a plurality of infrared heaters 3a arranged at a predetermined distance from the water A stored in the water tank unit 1 and a reflection plate 3b for converging infrared rays emitted from the infrared heaters 3a into one point. And is set so that the converged infrared beam converges on the water surface of the water A or at a position slightly deeper than the water surface. In FIG. 1, 5 is a suction port, 6 is a blowout port, and 7 is a ventilation passage.
The blower outlet 6 and the ventilation passage 7 are formed between the water tank portion 1 and the body 2 by mounting the body 2 on the water tank portion 1, and the air outside the machine is sucked in by the drive of the blower 4. 5
It is introduced further and is blown out from the air outlet 6 through the ventilation passage 7.

Reference numeral 8 denotes a tank mounted on the upper surface side of the main body 2. The tank 8 is integrally molded with a transparent resin material and is formed into a hemispherical hollow body. This tank 8
Has a hermetically sealed interior, and is integrally formed at the bottom with a supply cylinder 9 that communicates only with the outside. The supply cylinder 9 is formed in a cylindrical shape and vertically installed.
A cap 10 as shown is provided. The cap 10 is attached to and detached from the tip of the supply cylinder 9 by screwing, and has an opening 11 formed at the center and a valve 12 for opening and closing the opening 11. This valve 12 is the second
As shown in the figure, a valve body 12a for opening and closing the opening 11,
A spring 1 for constantly urging the valve body 12a in the closing direction of the opening 11.
It is composed of 2b and. On the other hand, the water tank portion 1 is provided with a protrusion 13 at a position facing the opening 11, and when the tank 8 is attached to the main body 2, the protrusion 13 causes the spring 12 to move.
The valve body 12a is pushed up against the force of b to open the opening 11. The tip of the supply cylinder 9 is located at a position where the water level of the water tank portion 1 is 1, and the water in the tank 8 is sequentially supplied to the water tank portion 1 as the water level decreases. The water level 1 of the water tank portion 1 is set to a water level at which evaporation is most efficiently performed by irradiation with an infrared beam.

The operation of the humidifier having the above configuration will be described.

First, the cap 10 is taken out, water is supplied from the supply cylinder 9 into the tank 8, and the cap 10 is screwed again. In this state, when the tank 8 is mounted on the main body 1 mounted on the water tank portion 1, the protrusion 13 provided on the water tank portion 1 causes the protrusion 13 on the valve body 12a.
Is pushed up to supply the water in the tank 8 to the water tank portion 1 up to a predetermined water level 1 (the tip of the supply cylinder 9). When the infrared heater 3a is energized in this state, the heater 3a emits infrared rays, and the emitted infrared rays are converged by the reflection plate 3b and are applied to the water A stored in the water tank portion 1. By the irradiation of the infrared beam, the stored water A rises in temperature and gradually evaporates. At this time, when the blower 4 is driven, the outside air is introduced into the ventilation passage 7 through the suction port 5 and is blown out into the room through the blowout port 6 together with the evaporated water. The room is humidified by this evaporation.

In this case, the water that evaporates is heated and evaporated by the infrared beam irradiated near the water surface, so the temperature is about 60 ° C in the blown state, and there is no risk of burns even if it comes into direct contact with humans. Absent. Moreover, since the temperature is appropriately raised, even if the air blown from the humidifier is used in combination with heating, there is no feeling of cold air and it is comfortable. Further, when the water is directly evaporated by the heater, a boiling noise is generated, which is uncomfortable. However, by indirectly heating with the infrared beam as in the above embodiment, there is no boiling noise and the noise can be reduced.

In such a humidifier, impurities of water gradually accumulate inside the water tank portion 1 during use. In this case, it is necessary to clean it regularly. For cleaning, first the tank 8 is removed from the main body 2, and then the main body 2 is removed from the water tank part 1. By doing so, the water tank unit 1 becomes an independent single member, but all the electric parts such as the heating unit 3, the blower 4, and the control circuit are mounted on the main body 2, and the water tank unit 1
Since no electric parts are mounted on the water tank, the water tank portion 1 is like a plate, so to speak, and can be easily washed. When the washing of the water tank portion 1 is completed, the main body 2 may be attached to the water tank portion 1 and the tank 8 may be attached to the main body 2.

Now, in the above embodiment, the tank 8 is
Since the bacteria stored in the water may gradually propagate, it is necessary to wash it regularly. The tank 8 is
Since only the supply cylinder 9 communicates with the outside, this supply cylinder 9
The inside of the tank 8 may be cleaned by using. in this case,
If the diameter of the supply cylinder 9 is set to be large enough to handle, it is possible to put the hand inside the supply cylinder 9 and efficiently wash the inside of the tank 8.

In the embodiment shown in FIG. 1, the heating unit 3, the blower 4,
The supply cylinders 9 are arranged in the same row, but in order to make the diameter of the supply cylinders 9 large enough to handle, the positions of the heating unit 3, the blower 4, and the supply cylinders 9 should be set uniformly at 360 °. If the heating unit 3, the blower 4, and the supply cylinder 9 are arranged in each of the three divided areas, the diameter of the supply cylinder 9 can be increased without increasing the size of the humidifier itself. The inside of 8 can be easily cleaned.

It should be noted that in FIG. 1, reference numeral 14 denotes a recess formed at an appropriate location (for example, three locations) on the outer periphery of the tank 8, and the recess 8 is used as a clue so that the tank 8 can be easily removed from the main body 2.

FIG. 3 is a sectional view of another embodiment. As shown in FIG. 3, the outer circumference of the main body 2 may be extended downward over the entire circumference to conceal the water tank portion 1 so as to have a neat appearance. In this case, the suction port and the air outlet are formed at appropriate positions.

<Effect> Since the humidifier of the present invention has the above-described configuration, when debris is generated in the water tank, the main body detachably attached to the upper surface of the water tank can be removed from the water tank. , Electrical parts such as the heating part and the blower can be removed from the water tank part at the same time, and the water tank part can be cleaned like a dish without any electrical parts mounted on it. Cleaning can be performed extremely easily and reliably without any consideration of water intrusion into electrical parts.
In addition, since the ventilation passage is formed only by mounting the main body on the upper surface side of the water tank portion, it is not necessary to separately form this ventilation passage, and the configuration of the humidifier can be extremely simplified.
