Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a humidifier for humidifying indoor air.

Conventionally known humidifying devices are classified into ultrasonic type, spray type, filter vaporization type, heating evaporation type, etc. according to their humidification type.

However, each of these types of humidifying devices has the following drawbacks.

Ultrasonic and spray humidifiers directly turn water into mist, so impurities such as calcium and magnesium dissolved in the water mix with the mist particles and scatter, causing the mist to vaporize. When the floor surface is not clean, this impurity turns into white powder and becomes a drawback.

(B) Filter vaporization type humidifiers create humid air by blowing air through a water-containing filter, so no fog is generated and the humidified state is invisible.

Additionally, in order to perform large amounts of humidification, this type of humidification requires a correspondingly sized filter, resulting in an increase in the size of the device.

Furthermore, this method has the disadvantage that the humid air is at a low temperature, which lowers the indoor temperature.

(C) Since the heating evaporation type humidifying device uses heated steam, it has the disadvantage that the steam temperature is high and dangerous.

The present invention is a new type of humidifying device that mixes high temperature steam and low temperature saturated humid air to generate humidifying mist, and solves the various drawbacks of the above-mentioned systems.

The present invention will be described below with reference to the drawings.

1 is a humidifying filter made of urethane foam with open cells, which is treated with hair flocking to facilitate the adhesion of water, and allows air to pass through to promote vaporization.

Reference numeral 2 denotes a blower for blowing air to the humidifying filter 1, which sucks air from the outside and causes it to pass through the humidifying filter 1.

Reference numeral 3 denotes a water sprinkling disk for adhering water to the humidifying filter 1. Water is sprinkled by rotation of this disk, and water is adhering to the humidifying filter 1.

4 is a watering tank that stores water for watering, and is replenished from outside the tank to keep the water level constant.

Reference numeral 5 denotes a filter evaporation section consisting of a humidifying filter 1, a blower 2, a water sprinkling disk 3, and a water sprinkling tank 4.

Reference numeral 6 denotes an aluminum heating plate that is heated to evaporate water. Water is supplied from the outside to keep the amount of water constant, and a heater is provided on the bottom.

Reference numeral 7 denotes a heater that is brought into close contact with the bottom surface of the heating plate 6, and is an electric heater P, T, and C heater.

Reference numeral 8 denotes a heating evaporation section consisting of a humidifying tray 6 and heaters 7 of P, T, and C.

Reference numeral 9 denotes a mixing chamber for mixing the vaporized air port from the filter vaporizing section 5 and steam from the heating evaporator section 8, and 10 indicates an outlet for blowing out the mixed humidified air.

Reference numeral 11 denotes a cartridge tank portion for replenishing water to the watering tank 4 and the heating plate 6, which are connected by a water pipe.

A is the air sent from the blower 2 to the humidifying filter 1, the mouth is the vaporized humid air that has passed through the humidifying filter 1, and C is the heating plate 6
(2) is the humidified air that is blown out after mixing the vaporizing air port and the steam (3) in the mixing chamber 9.

In the humidifying device described above, first, the water supplied from the cartridge tank 11 to the watering tank 4 is rotated 30 times by the watering disk, and the centrifugal force causes the water to adhere to the humidifying filter 1.

At this time, the surface of the humidifying filter 1 is treated with flocking treatment, so that a large amount of water adheres to it and the surface area of the water becomes large.

Air from the outside is blown through the humidifying filter 1 by a blower 2, and is passed through the humidifying filter 1.

During this passage, the water adhering to the humidifying filter 1 evaporates at a low temperature due to the spectacular scenery and atmospheric pressure of the air, and becomes a evaporative humid air port.

Similarly, by supplying water to the heating dish 6 and heating it with the heater 7, the water in the heating dish 6 is boiled and steam is produced.

This vaporized moist air port and high-temperature steam are mixed in a mixing chamber 9, lowered to about room temperature, and blown out from an exhaust port 10.

In particular, other configurations other than those described above can be considered for attaching water to the humidifying filter 1 in the filter vaporizing section 5. For example, even if the humidifying filter 1 is made into a cylindrical shape and rotated with an axis parallel to the water surface, the humidifying filter 1 may be It is possible to attach water to the filter 1, and this embodiment shows an example of a configuration in which water is attached to the humidifying filter 1.

The generation of fog in humidifiers as explained above is achieved by first mixing high-temperature steam and low-temperature saturated humid air in a mixing chamber and blowing it out to the outside to lower the high-temperature steam to about room temperature. condenses to form particles,
This becomes a visible white mist.

The amount of this white fog, that is, the supersaturated moisture present in the mixed air, is absorbed by the dry air when the temperature of high-temperature steam is lowered by dry air. The fog increases in volume by lowering the temperature of the hot steam with saturated air.

The present invention generates a large amount of fog by mixing high-temperature steam in the heating evaporation section and low-temperature humid air in the filter evaporation section, cooling the high-temperature steam, and blowing it out from the exhaust port as described above.
The humidified state is visible as white, and the particles of this mist are so fine that they do not stick to your hands.

The mist blown out from the outlet has a temperature around room temperature, which is very safe and does not lower the room temperature due to humidification.

Further, the humidifying device of the present invention performs clean humidification that does not contain impurities dissolved in water, which is good for hygiene, and is also ideal for humidifying furniture and the like.

Conventionally, in order to perform mass humidification, the filter evaporation type had the drawbacks of being large in size and the heating evaporation type requiring large amounts of power, but with this device, the large amount of humidification can be distributed and allocated to both. It has the advantage of being compact and does not require large amounts of power.

The filter vaporization section and heating evaporation section can be operated individually or in combination depending on the usage situation. For example, when you want to lower the temperature of the room (if not, use the heating evaporation section or the combination to automatically adjust humidity) It is convenient to use the filter vaporizer when you want to use it with low power or use both when it is too dry.

Furthermore, since the two are used in combination, the high-temperature steam in the heating and evaporating section is sucked in by the blowing of moist air and does not form condensation on the wall of the nozzle area such as the mixing chamber (it is not blown out to the outside for evaporation and humidification). This has the advantage of increasing efficiency.

Furthermore, the performance of the humidifying device of the present invention is not affected by water quality, and as explained above, the present invention generates a humidifying mist by combining a filter vaporization section and a heating evaporation section, which is not the initial purpose of the present invention. This is a humidifying device that naturally satisfies the above requirements, takes advantage of the individual effects, compensates for the individual drawbacks, and by combining the two, creates new effects as shown in the numerous advantages mentioned above.
