Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a humidifier of a vaporization type or the like for preventing indoor drying due to the use of a heating appliance used in a general household.

[0002]

2. Description of the Related Art A conventional general humidifier is, for example, shown in FIG.
As shown in FIG. 1, a humidifying element 16 is installed near the air outlet 2 in the case 19 in which the air inlet 1 and the air outlet 2 are formed.

The humidifying element 16 is made of a material in which a tubular moisture-permeable membrane having a certain surface area passes only water vapor without passing through water and components dissolved in water. A blower 3 is provided near the suction port 1 in the case 19, and the blower 3 is
have.

Further, a water supply tank 17 is provided above the humidifying element 16, and water can be stored in the water supply tank 17.

A heater 18 is provided between the fan 10 and the humidifying element 16, and the air is heated by the heater 18 before the indoor air is blown by the fan 10 to the moisture-permeable membrane of the humidifying element 16. It was configured to be able to.

(See, for example, Japanese Patent Application Laid-Open No. 9-273772, etc.)

[0007]

The humidifier in the above-mentioned conventional construction is, for example, heated by a heater 18 before air in a room is blown by a fan 10 to a moisture permeable membrane of a humidifying element 16. Since the temperature of the moisture permeable membrane is increased to generate steam, the temperature of the moisture permeable membrane, the water in contact with the water, and the humidifying element 16 itself are not increased, and the warm air heated by the heater 18 is cooled. Is done.

Further, there is a problem that the amount of warm air passing between the humidifying elements 16 is large and the efficiency is very poor.

[0009]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has an air blower for blowing air to a suction port for sucking dry air in a room and an air outlet for sending air to a room. A water supply unit comprising a vaporizing filter having a property, a water tank unit for supplying moisture to the vaporization filter, and a water supply tank having a valve body that holds the water in the water tank unit at a constant water volume and opens by pressing. A humidifier configured to form an air passage through which a dry air in a room obtained from an intake port by the blower passes through a vaporization filter portion moistened with water in a water tank portion and flows to an outlet. The vaporization filter had a heater.

Further, a heater is arranged on the surface of the vaporizing filter.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention has a constitution in which a heater is provided in a vaporization filter as described above.
The heater provided in a part of the vaporization filter raises the temperature of the vaporization filter, and the loss is reduced by directly warming the vaporization filter and the water sucked up by the vaporization filter. The vaporization can be promoted only by giving a little energy of the dry air in the room obtained from.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In the figure, a blower 3 mainly composed of a combination of a motor 9 and a fan 10 is installed below a blower outlet 2 in a main body 11 by a fixture 12, and a bell provided near the fan 10 is provided. At the lower end, a water-absorbing vaporizing filter 4 is installed at the lower end of the water tank 5 via the mouth 13.

The vaporizing filter 4 has a heater 8. For example, the heater 8 is arranged on the surface of the vaporizing filter 4.

Further, on the surface of the vaporizing filter 4,
A planar heater 15 having a plurality of slits 14 is integrated, so that dry air in a room passes through the slits 14.

The planar heater 15 may be either the inner surface or the outer surface of the vaporizing filter 4, but the outer surface is good in consideration of wiring to the electrodes and heat exchange efficiency.

A water tank unit 5 for supplying water to the vaporizing filter 4 is provided with a water supply unit 7 comprising a water supply tank 6 having a valve element which holds the water in the water tank unit 5 at a fixed amount and is opened by pressing. And the blower 3
The dry air in the room obtained from the suction port 1 provided in the main body 11 passes through the vaporization filter 4 portion moistened with water and forms an air passage flowing to the blowout port 2.

Next, the operation of the above configuration will be described.

For example, by operating the main body 11,
Electric power is supplied to the planar heater 15 attached to the vaporizing filter 4, the temperature of the planar heater 15 rises, and the vaporizing filter 4 which is immersed in the water of the water tank 5 is supplied with water in the water tank 5 by capillary action. Since the water is sucked and moistened, the vaporizing filter 4 and the water are directly heated, and the energy of the warmed portion is replenished as vaporizing energy, so that less energy is absorbed from the dry air.

Further, even if the dried air hits the sheet heater 15, the hit air takes away the heat of the sheet heater 15, but the air is further dried, so that the air tends to contain moisture. The air that has absorbed moisture from the filter 4 and has no waste is discharged from the outlet 2 into the room.

[0021]

As described above, according to the present invention, as described above,
By integrating the vaporizing filter and the heater, the humidifying efficiency of exchanging the heat energy of the heater with the energy for moistening the dry air in the room (vaporizing the water) can be improved, thus saving energy. I was able to.
