Description

[Detailed Description of the Invention] The present invention relates to a humidifier used for air conditioning in houses.

Open-type gas stoves and kerosene stoves, which have been developed as the mainstream heating appliances for homes, have the disadvantage of contaminating indoor air, so closed-type heating appliances (e.g. gas-fired, kerosene-fired hot-air heaters, etc.) ) Demand is gradually shifting to 5.

Since these devices also significantly dry indoor air, humidifiers are becoming popular for controlling humidity.

By the way, humidifiers commonly used in the past include a heater heating plate type humidifier and an ultrasonic atomization type humidifier.

The former method heats the water container with an electric heater or the like, or inserts a sheathed heater into the water container to heat the water and evaporate it directly, but as time passes, calcium, magnesium, etc. evaporation residue precipitates and deposits sludge in the water container.

As a result, the amount of humidification is greatly reduced and the electric heater is overheated and disconnected, so it is necessary to clean the sludge, which is troublesome.

Moreover, in this case, it was not possible to freely control the amount of humidification.

□The latter uses ultrasonic energy to atomize water,
Although it is released in the form of a mist, this mist comes into contact with the indoor air and absorbs the latent heat of vaporization and turns into water vapor, causing a drop in indoor temperature.

Also, depending on the conditions near the fog outlet, water droplets may adhere to the area.
This may drip down and contaminate furniture, etc.

Furthermore, in this case, there is a problem that the evaporation residue scatters in the form of fine powder in the indoor air, and this adheres to the surfaces of furniture and the like, causing cloudy contamination.

Moreover, in this case as well, it was not possible to freely control the amount of humidification.

The present invention improves the above-mentioned drawbacks, linearly controls the amount of humidification, and accurately adjusts the humidity of indoor air.One embodiment of the invention will be described below with reference to the drawings.

FIG. 1 is a longitudinal cross-sectional view of this embodiment, and FIG. 2 is a cross-sectional view of the same, showing the state of scattering of atomized particles.

In FIG. 1 and FIG. 2, 1 is an atomizer, and a damper 2 inscribed therein is rotatable.

3 is a rotating plate on which the opening of the water supply pipe 4 is exposed.

5 is a mist outlet that protrudes to the side of the atomizer 1, and a damper 2
The degree of opening can be adjusted by means of an adjustment lever 6.

Reference numeral 7 denotes an evaporator, and a removable water absorbing body 8 surrounded by the inner surface is made of a heat-resistant porous material such as porous ceramic or foamed metal, and is fixed with a lid 9.

Reference numeral 10 denotes a heater, which is fixed by a holding plate 11.

Reference numeral 12 denotes a mist inlet projecting to the side of the evaporator 1, into which the mist outlet 5 is fitted.

The fog inlet 12 and the fog outlet 5 are formed thin and are thermally insulated with a slight gap.

13 is a water vapor release port. Below the atomizer 1 is a fan case 15 having a fan impeller 14 and a motor 16.
A motor case 17 having a sub-tank 18 and a pump case 20 having a pump impeller 19 are arranged in series, and the rotating plate 3, fan impeller 14, and pump impeller 19 are connected to a rotating shaft 21 in a skewer shape and are driven by a motor 16. be done.

The leveler 23 on which the cassette tank 22 is mounted always maintains the amount of water in the sub-tank 18 connected thereto in a fixed position.

The discharge side of the pump case 20 is connected to the water supply pipe 4,
The drain port 24 provided at the bottom of the atomizer 1 is connected to the return pipe 2.
5, it is communicatively connected to the sub-tank 18.

Reference numeral 26 denotes an intake port provided in the motor case 17, which communicates with the suction side of the fan case 15, and the air exiting the discharge side of the fan case 15 is supplied into the atomizer 1 through the rotation shaft 21. .

To describe the operation of this embodiment configured as described above, a fixed amount of water is constantly supplied to the sub-tank 18.
First, electricity is supplied to the heater 10 to preheat the evaporator 7.

Next, when the motor 16 is energized and driven, the rotating plate 3,
The fan impeller 14 and the pump impeller 19 rotate, and the water sent from the pump case 20 flows down onto the rotating plate 3 through the water supply pipe 4, and the centrifugal force causes atomized mist to spread around the entire circumference. scatter.

Most of the generated fog is blocked by the damper 2 and drips, and is returned to the sub-tank 18 through the drain port 24 and the return pipe 25. The part that passes through the opening of the damper 2 is the fog outlet 5. It scatters into the evaporator 7 through the fog inlet 12.

At this time, the air sent into the atomization chamber 1 advances into the evaporator 7 together with the mist to help transport the koji.

The mist scattered in the evaporator 7 comes into contact with the water absorbing body 8 and is heated, becoming water vapor and dissipating into the room from the discharge port 13 together with the air.

Note that Figure 2 shows the damper 2 at its maximum opening, and if you increase or decrease the opening by operating the adjustment lever 6, the amount of mist passing, that is, the amount of humidification, will increase or decrease linearly in proportion to this. Therefore, the required amount of humidification can be easily adjusted.

In other words, the amount of humidification required to bring the indoor temperature to a comfortable temperature is mainly determined by the temperature and humidity of the outdoor air, the amount of ventilation due to drafts, etc., and the indoor temperature, but as mentioned above, the amount of humidification can be easily adjusted linearly. Anything that can be done has an important meaning in improving comfort.

Further, in this case, the mist in the evaporator 7 completes evaporation and is dissipated as water vapor from the outlet 13, so that the evaporation residue does not scatter indoors.

Furthermore, in this embodiment, the mist outlet 5 and the mist inlet 12 are formed thinly and are fitted with a slight gap.
There is little heat loss in the evaporator 7, and the amount of evaporation does not decrease.

Note that eugenic air is drawn into the gap through the draft of the airflow passing through the fog outlet 5, so no fog will leak out.

Further, since the mist outlet 5 is cooled by the air flow around the inner and outer peripheries, the temperature increase is suppressed, and therefore, there is no evaporation within the atomizer 1, so no evaporation residue is generated.

Most of the evaporation residue in the evaporator 7 adheres to the water absorbent body 8; This can be easily cleaned by removing the lid 9 and taking it out.

As described above, according to the present invention, the water vapor and air exiting the outlet do not contain evaporation residue or fog, so they do not contaminate the room.

Furthermore, since the amount of humidification can be easily and linearly adjusted, the accuracy of humidity control can be increased and comfort can be improved.

Furthermore, in the present invention, in which atomized particles are sent from the fog outlet of the atomizer to the fog inlet of the evaporator for humidification, the fog outlet and the fog inlet are connected through a gap. There is less heat loss due to heat conduction to the atomizer, which increases evaporation efficiency, and since there is no evaporation of atomized particles on the atomizer side, evaporation residue is generated inside the atomizer, inhibiting atomization. It doesn't cause any problems.
