Abstract

PURPOSE:To reduce a damage of a burn and to enhance a visual sensing effect during humidifying operation by heating a heating oven by a heater to generate steam, feeding the air by a blower and diffusing it together with the air out of a body in a state that the temperature of the steam is lowered. CONSTITUTION:When water in a heating oven 3 heated by a heater 5 is boiled, it becomes steam particles to be filled in an atomizing cylinder 7. The air from a blower 6 is fed from the opening 7a of the cylinder, and the particles are guided from a diffuser 8 out of the body. In this case, the steam fed out of the diffuser 8 is cooled to about 70 deg.C. Accordingly, in comparison with the case that the steam is directly diffused, a danger of a burn can be reduced. Since a steam generating amount is apparently increased due to agitating by the air and its rising speed is increased, the visual sensing effect of humidifying operation can be enhanced.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a humidifier for controlling indoor humidification.

BACKGROUND OF THE INVENTION In recent years, humidifiers have been used to increase the relative humidity in heated rooms during the winter. Conventionally, this type of humidifier has had a configuration as shown in FIG.

That is, the main body 101 has a built-in heating pot 103, and the bottom of the heating pot 103 is connected to the bottom of the water tank 102 and the pipe 10.
4, and water is supplied to the heating pot 103. A heater 105 for heating is wound around the outer periphery of the heating pot 103. Additionally, water vapor is placed above the heating pot 103 in the main body 1.
01 is connected to an atomizing cylinder 106 that leads to the outside.

Further, the lower opening of the main body 101 is covered with a metal bottom plate 107. The water tank 108 is removably housed on the mounting table 101a of the main body 101.
8 supplies water to the water tank 102 and the heating pot 103. The water level was adjusted by the water tap 108a of the water tank 108 to keep the water level in the water tank 102 and the heating pot 103 constant.

Problems to be Solved by the Invention In such a conventional configuration, vapor particles heated in the heating pot 103 pass through the atomization tube 106 at a high temperature of about 90° C. and exit the main body. There was a problem that there was a risk of burns if hands were carelessly placed near the air outlet. Furthermore, even though steam is generated when the humidifier is operated, the rising speed of the steam particles is slow, so there is a problem in that the visual effect during humidification operation is weak.

Furthermore, even if an attempt is made to attach a humidity sensor to the main body 101 in order to automatically control the amount of humidification, the main body is heated due to heat transfer from the heater 105, and the humidity sensor 1 is heated by the heat transferred from the heater 105.
09 malfunctions, and the humidity sensor cannot be easily attached.

The present invention solves these problems, and its first objective is to lower the temperature of the generated steam to reduce the risk of burns, and to increase the rising speed of the generated steam to enhance the visual effect of humidification operation. This is the purpose.

The second purpose is that the humidity sensor installed inside the main body can operate normally without being affected by heat, and the amount of humidification can be automatically controlled.

Means for Solving the Problems In order to achieve the first object, the first means of the present invention is to provide a heating pot for heating water built into the main body, a water tank for supplying water to the heating pot, and the heating pot. The atomizing tube has an atomizing tube that guides water vapor generated by the main body to the outside of the main body, an aperture formed in the side surface of the atomizing tube, and a blower device that blows air into the aperture. .

A second means for achieving the second purpose is to connect an air intake hole formed on the outer surface of the main body, an air blower built into the main body, a suction side of the air blower, and an air intake hole of the main body. It has a humidity sensor installed in between, and a bottom plate assembly that covers the opening surface below the main body, and this bottom plate assembly includes a metal bottom plate installed below the heating pot around which a heater is wound, and a bottom plate assembly below the humidity sensor The structure includes a synthetic resin bottom plate that is installed in the bottom plate.

Effect: Due to the configuration of the first means, air is sent from the blower provided in the main body to the atomizing tube, and is blown out from the outlet of the atomizing tube together with steam particles, thereby removing the steam near the outlet. The temperature is reduced, and the hot steam particles are stirred and accelerated by the blowing action, so that the amount of steam generated appears to increase, and the rate of rise of the steam also increases.

With the configuration of the second means, by arranging the humidity sensor between the air blower and the air intake port of the main body, the ambient temperature around the humidity sensor is kept almost constant, and the bottom plate covering the lower part of the humidity sensor is made of synthetic resin. By making it made of aluminum, it is possible to prevent heat transfer from the heater and maintain the humidity sensor in a stable state.

Embodiment First, an embodiment according to the first means of the present invention will be described based on FIG. As shown in the figure, the main body 1 is provided with a heating pot 3, and a water tank 2 is built in on the side of the heating pot 3 at approximately the same height. The bottom of the heating pot 3 is connected to the bottom of the water tank 2 and the pipe 4.
are connected.

A heating heater 5 is wound around the outer periphery of the heating pot 3. Further, a blower device 6 is installed in the lower part of the main body 1 to convey the steam generated from the heating pot 3 by wind, and an air intake port 9 is formed in the side surface of the main body 1. The upper part of the heating pot 3 is provided with an atomizing tube 7 for guiding water vapor to the outside, and an opening 7a is provided on the side of the atomizing tube 7 to take in air from the blower device 6. At the upper end of the atomizing cylinder 7, a rotatable blow-off port 8 is mounted which allows the blow-out direction of steam to be changed arbitrarily. Further, the water tank 13 is removably placed above the water tank 2 of the main body 1, and water is supplied from the water tank 13 to the water tank 2 to keep the water levels in the water tank 2 and the heating pot 3 constant.

The operation of the above configuration will be explained below. First, the heater 5
When the heated water in the heating pot 3 boils, it becomes vapor particles and fills the atomizing cylinder 7.

Air from the air blower M6 flows into the atomizing cylinder through the opening 7a, and the vapor particles are led out from the air outlet 8 to the outside of the main body.

At this time, the water vapor coming out of the outlet 8 is cooled down to a temperature of about 70°C. Therefore, the risk of burns can be reduced compared to when steam is blown out directly. In addition, the amount of steam generated appears thicker due to the agitation caused by air blowing, and the rising speed also increases, so the visual effect of the humidification operation can be enhanced.

Next, an embodiment according to the second means of the present invention will be described based on FIG. 2. Components having the same configuration as the embodiment according to the first means will be designated by the same reference numerals, and detailed explanation will be omitted.

As shown in the figure, a humidity sensor 10 is provided inside the main body 1 between the suction side of the blower 6 and the air intake port 9 of the main body 1. Furthermore, the opening surface below the main body 1 is covered with a bottom plate set 11, which includes a metal bottom plate 11a and a synthetic resin bottom plate 1.
It is formed by joining the end face with 1b. The synthetic resin bottom plate 11b is placed below the humidity sensor 10, and the metal bottom plate 11a is placed below the heating pot 3, and the metal bottom plate 11a is provided with ventilation holes 11a.

In the above configuration, when the heater 5 is energized, the water in the heating pot 3 boils to generate steam, and the blower device 6 discharges the steam from the outlet 8. At this time, the metal bottom plate 1 of the main body 1
1a is also heated by the radiant heat of the heater 5, but the metal bottom plate 1
The metal bottom plate 11a is cooled by a portion of the air from the blower device 6 passing through the ventilation holes 12 provided in the metal bottom plate 1a. Furthermore, since the metal bottom plate 11a and the synthetic resin bottom plate 11b are combined or the synthetic resin bottom plate 11b can suppress the amount of heat transferred from the metal bottom plate 11a, the influence of heat on the humidity sensor 10 can be ignored. . In addition, since the humidity sensor] 0 is placed on the suction side of the air blower 6, the atmosphere around the humidity sensor 10 is kept at a nearly constant temperature, and the detection accuracy of the humidity sensor 10 is maintained well, allowing it to accurately sense humidity. can do. Furthermore, since the lower part of the heater 5 is covered with a non-flammable metal bottom plate 11a, even if the heater 5 falls, the danger of fire can be prevented.

Effects of the Invention As is clear from the above embodiments, according to the present invention, a heating pot is heated with a heater to generate steam, and a blower is used to blow air to lower the temperature of the steam. By blowing out of the main unit with the wind, the risk of burns is reduced, and the amount of steam generated increases in appearance and the rate of rise of steam also increases, which has the effect of increasing the visual effect during humidification operation. It will be done.

Furthermore, by installing the humidity sensor between the air intake port of the main body and the wind suction side of the blower, the temperature around the humidity sensor can be kept almost constant. In addition, by making only the lower part of the humidity sensor of the bottom plate made of synthetic resin, the influence of heat radiation from the bottom plate can be reduced, and the humidity sensing accuracy of the humidity sensor can be maintained and the humidity control function can operate normally. There is an effect.
