Description

{Forced Evaporative Humidifier}

More particularly, the present invention relates to a forced evacuation type humidifier, in which humid air sucked from the upper part is sucked and humid air having passed through the evaporation part is discharged toward the lower part of the room suitable for convection, and the discharged air is uniformly humidified by natural air circulation And more particularly, to a forced-evaporative humidifier which can be operated by a user. It also includes a top cover with opening and closing functions for easy water supply and maintenance. It also includes the function of heating the air after the humidification process.

Generally, humidifiers are ultrasonic, heated, evaporated. In addition, the evaporative humidifier has a natural evaporation type and a forced evaporation type.

The natural evaporation type humidifier absorbs the water contained in the water tank by the evaporation capillary capillary phenomenon, and the wet evaporation evaporates naturally. Such a natural evaporative humidifier has advantages of simple structure and low cost, but it has a disadvantage in that humidification efficiency is inferior.

On the other hand, the forced evaporative humidifier is a method of increasing the humidifying efficiency by supplying air using a fan. This forced evaporative humidifier is called an air washer because it has an air cleaning effect that adsorbs foreign substances in the air during the humidification process. Such a forced evaporative humidifier includes a disk rotation system, a water circulation system, and an evaporation filter system.

The disc rotation method is a method of humidifying the disk by absorbing water while supplying the air to the fan. The disk can be used semi-permanently, but since it needs to disassemble, clean, and re-assemble dozens of disks, cleaning can be quite cumbersome.

In the water circulation system, when water is supplied to the evaporation part by a pump, water is flowed down by gravity and humidification is performed by supplying air to the fan. The evaporator has a structure that increases the humidification efficiency by enlarging the surface area by a large number of plates or a porous structure. Water circulation system also requires cleaning and reassembling of the evaporation part during cleaning, which makes it difficult to maintain. Especially, since it is difficult to clean the inside of the pump and piping, there is a hygiene problem when using for a long time.

The evaporative filter method is a method of absorbing water contained in a water tank as a capillary phenomenon and humidifying the wet filter by supplying air to the fan. Compared with the disk rotation method and the water circulation method, the structure is simple and easy to clean. However, there is a disadvantage that the filter must be replaced after a certain period of time.

The direction of the convection in the room is that the light air circulates upward and the heavy air circulates downward. For example, the air heated by a warm floor or a heating device rises and the air cooled down from the ceiling or wall falls. Through this process of convection, the room air circulates.

In addition, the humidity distribution of the room shows heavy and humid air in the lower part of the room, and light and dry air in the upper part of the room. That is, the humid air is heavy, so it descends downward, and the dry air is lighter, so it has the property of going upwards. Therefore, convection and circulation of air are important to maintain the humidity of the room evenly.

When the water evaporates in a natural evaporative humidifier, the humidified air becomes obviously heavy. Therefore, the humidified air is lowered, and the surrounding air is moved to the evaporating portion of the humidifier and the humidification is repeated. In this case, since there is no blowing fan and the flow velocity is slow, it can be moved slowly by convection.

However, in the case of a forced evaporative humidifier, since forced air is blown by a fan, it is necessary to take into account the circulation of air and the circulation of air, since the airflow of the humidified air can be discharged in any direction.

However, most conventional forced evaporative humidifiers have a structure in which air is sucked from the side or bottom of the humidifier and the humidified air is discharged to the top. The humidifying efficiency is inferior to that in the case of relatively inhaled air at the lower part of the room. In addition, since the humid air is discharged to the upper part, the air is discharged in the opposite direction of the convection, which is not suitable for air circulation through convection.

The forced evaporative humidifier and the indoor air flow according to the prior art will be described in detail with reference to FIG. The conventional evaporative humidifier includes a humidifier main body 20, an air inlet 21, a water tank 22, an evaporator 23, a fan 24, and an air outlet 25. The air inlet 21 is located on the side or bottom of the humidifier. Therefore, the air sucked by the humidifier can be said to be the air in the lower indoor portion (10) which is relatively high in humidity. The air introduced through the air intake port (21) is humidified while passing through the evaporator (23). The evaporator 23 absorbs water as the disc is immersed in water when a plurality of discs half contained in the water tank 22 are rotated by a disc rotation method. When the air passes through the evaporator 23, the humidity rises and the temperature of the air drops due to the latent heat of evaporation of the water, so that the air becomes heavy and cold. The humidified air is discharged by the fan (24) through the air outlet (25) at the top of the humidifier. Since the discharged air is heavy and cold air, it is difficult to reach the upper layer 12 of the room, and even if it reaches it, it can not stay in the upper layer 12 of the room but falls down. In other words, the exhausted air can not go far and remains on the floor near the humidifier. Moreover, since the air is again sucked through the air inlet 21, the humidity near the humidifier is high, but the humidifier can not be evenly humidified.

Referring to FIG. 3 again, the indoor air flow is relatively heavy and humid at the bottom of the room. When the air is heated by the warm floor or the heating mechanism 14, it is raised. The raised air pushes out the relatively light and dry indoor upper layer 12 air, and when the pushed air is cooled from the ceiling or the wall, it is lowered. This process of convection is the most important part of indoor air circulation. However, in the forced evaporation type humidifier according to the related art, the air in the lower portion 10 of the room having a relatively high humidity is sucked by the side air inlet 21 or the air inlet 21 on the lower portion, and the heavy and cold air is humidified by the air outlet 25, It is not suitable for natural air circulation and it is found that there is a problem in evenly humidifying the room.

Among the conventional forced evaporative humidifiers, there is also a method of blowing air from the upper part to the lower part. Referring to FIG. 4, a discharge air flow of a conventional forced evaporative humidifier which blows downward from the top will be described. A fan (24) is positioned above the humidifier. The fan (24) blows air to the evaporator (23) located at the bottom of the fan. The evaporator 23 is a system in which water contained in the water tank 22 is absorbed by a filter by an evaporative filter method and air is supplied to the fan to humidify the water. However, since the humidifier does not consider the discharge direction of the humidified air, the discharged air is dispersed in an irregular direction. Some of the air can be discharged to the side, but the air striking the evaporator 23 and the water tank 22 is dispersed in an irregular direction, and in particular, the air discharged to the bottom collides with the bottom, resulting in a severe turbulent flow. These irregular directions and turbulent flow are not suitable for convection and air circulation in the room. Therefore, in the conventional forced evaporative humidifier which blows downward from the upper part, humidification is performed by sucking air from the upper part, but this is for the purpose of supplying air to the evaporator 23, It is not considered.

As described above, the conventional forced evaporative humidifier has been considered, considering the performance of the humidifier itself, but does not consider the characteristics of the air sucked by the humidifier and the air discharged by humidifying. Particularly, It can be seen that it is not suitable for air circulation or convection in the room since the air flow is not considered.

In addition, the conventional forced evaporative humidifier is troublesome in terms of maintenance. The disk rotation method and the water circulation method are considerably cumbersome because the inner evaporator must be disassembled and cleaned and then reassembled. Also, the evaporative filter method must be disassembled for internal cleaning, so maintenance can be inconvenient.

Further, due to the characteristics of the conventional forced evaporative humidifier, when water evaporates, the temperature is lowered due to latent heat of evaporation. Especially in the winter when the cold wind from the humidifier is uncomfortable to use. To raise the temperature away from the latent heat of vaporization, it is sufficient to raise the temperature of the water or to heat the air. However, when the temperature rises inside the humidifier, hygiene problems may occur because fungi or bacteria may multiply in the water tank or the evaporator.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a humidifier for humidifying a humidified air, And the discharged air is uniformly humidified by natural air circulation.

The present invention also provides a forced evaporative humidifier having a convenient maintenance such as cleaning and water supply.

In addition, the forced evaporative humidifier has a top cover that is easy to open and close, and thus it is possible to provide a humidifier that is convenient to maintain and manage, such as water supply and cleaning.

In addition, the forced evaporation type humidifier has a function of heating the humidified air after humidifying, so that it is possible to provide hygienic warm air without changing the temperature inside the humidifier.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

2 and 5, an embodiment of a forced evaporative humidifier according to the present invention will be described. The forced evaporation type humidifier according to the present invention includes an air inlet 21, a water tank 22, a vaporizer 23, a fan 24, an air outlet 25, and an upper lid 30 which can be opened and closed.

It can be seen that the air inlet 21 is located at the top of the humidifier in order to suck air relatively light and low in humidity.

The air inlet 21 may be provided with an air filter.

The air introduced through the air inlet 21 is supplied to the inside of the humidifier by the fan 24.

The fan 24 includes a wind speed control and a timer function.

And an operation switch 34 for operating the fan 24 and controlling the wind speed and the timer.

The water storage tank 22 has a detachable structure that facilitates cleaning and reduces the cross-sectional area when the water level is lowered, so that the water level can be maintained even with a small amount of water. And a water level display window 27 on the outside of the water tank to confirm the water level.

In this embodiment, the evaporator 23 absorbs the water of the water tank 22 by the evaporation filter method, and humidifies when the air passes through the evaporator 23.

The forced evaporative humidifier according to the present invention is not limited to the evaporative filter system, and various forced evaporative humidification systems such as a disk rotation system, a water circulation system, and an evaporative filter system can be used.

And a fixed sealing device 26 for supporting and fixing the evaporator 23.

The fixed sealing device 26 is structured such that the evaporation filter is fixed, and at the same time, a portion excluding the water tank and the evaporator is closed to prevent water and air from entering.

The humidified air is discharged through the air outlet 25.

The air outlet 25 has a structure in which the humidified air is discharged in a gentle downward slope toward the indoor lower layer portion 10. The discharged air can be uniformly humidified by natural air circulation through convection.

According to the present invention, there is provided an upper cover 30 which can be easily opened and closed for easy water supply and maintenance.

And a hinge portion 31 and a lid fixing portion 32 for opening and closing the upper lid 30.

The upper lid 30 may include a fan 24 and a fan safety net 33.

Hereinafter, the flow of the exhaust air according to the exhaust angle of the air outlet 25 of the forced convection type humidifier according to the present invention will be described with reference to FIG.

According to the present invention, after humidification, heavy air is discharged through the air discharge port (25) toward the indoor lower layer portion (10). In addition, the discharged air should naturally be distributed in the direction of the underfloor part 10 without being dispersed in all directions or turbulent flow. Therefore, the discharge angle of the air outlet 25 is very important.

In the case of discharging in the horizontal direction (0 DEG), since the discharge air is heavy, it slowly spreads downward toward the lower floor part 10 of the room. Further, when discharging at a gentle downward inclination (0 DEG to 45 DEG), it can move smoothly in the direction of the indoor lower layer portion 10 without dispersed or turbulent flow.

Conversely, if it is discharged vertically (90 °) or steeply sloping (45 ° to 90 °), the exhaust air will hit the floor to disperse or turbulently flow.

Therefore, the discharge angle of the air discharge port 25 must be discharged in a horizontal or gentle downward slope at an angle of 0 ° to 45 ° so that the discharged air can be smoothly moved toward the indoor lower layer portion 10 without dispersing or turbulent flow .

Hereinafter, a forced evaporative humidifier and indoor airflow according to an embodiment of the present invention will be described with reference to FIG.

The forced evaporation type humidifier according to the present invention sucks relatively dry air through the air intake port 21 located at the upper side and the humidified air that has passed through the evaporation unit 23 is discharged through the air discharge port 25 located at the side . Since the exhaust air is heavier through the humidification process and is cooled by the latent heat of evaporation of water, it must be discharged toward the lower part of the room 10, and the discharged air should not be dispersed in an irregular direction or turbulent flow. Therefore, the air outlet 25 according to the present invention has a structure in which the air is discharged in a gentle downward slope toward the lower floor part 10 of the room.

And is raised when the discharged air is heated by the warm bottom or the heating mechanism 14. This raised air pushes out the relatively light and dry upper air layer (12) and the lowered air is cooled down from the ceiling or wall. The descending relatively dry air is again sucked through the air intake port 21 located at the upper portion of the humidifier, so that effective humidification by air circulation becomes possible.

Therefore, the forced evaporative humidifier according to the present invention can humidify the room evenly by natural air circulation through such convection.

According to the features of the present invention, since humidification is performed by sucking air having a relatively low humidity through the air intake port 21 in the upper portion of the humidifier, the humidification efficiency is improved as compared with the case of sucking the air having a relatively high humidity in the side or lower portion There are advantages. In addition, since the humidified air is discharged in the direction of natural convection, the circulation of air is improved and the room can be evenly humidified. In addition, since the air can be humidified repeatedly by sucking dry air through the air circulation, effective humidification becomes possible. Among the conventional humidifiers, there is a method of blowing air from the top to the bottom. However, since the discharge direction of the air after the humidification is not taken into consideration, the discharged air is discharged in an irregular direction and is not suitable for air circulation because of turbulent flow.

Hereinafter, the function of opening and closing the upper cover 30 of the forced evaporation type humidifier according to the present invention and the maintenance function will be described with reference to FIGS.

The forced evaporation type humidifier according to the present invention includes a hinge portion 31 and a lid fixing portion 32 for opening and closing the upper lid 30 easily. When the upper lid 30 is opened, water can be easily supplied to the water tank 22. [ Also, if the upper lid 30 is opened and the fixed closing device 26 is disassembled, the evaporator 23 can be easily removed or replaced, or the water tank 22 can be separated and cleaned. Therefore, according to the present invention, maintenance such as water supply and cleaning becomes easy.

Hereinafter, another embodiment of the forced evaporative humidifier according to the present invention will be described with reference to FIG. The forced evaporation type humidifier according to the present invention includes an air inlet 21, a water tank 22, an evaporator 23, a fan 24, an air passage 40, an air chamber 41, and an air outlet 25 And a hinge portion (31) for opening and closing the upper lid (30) and a lid fixing portion (32). It also includes a heater 42 for heating the air.

The air sucked into the air intake port (21) moves to the evaporator section (23).

The evaporator 23 is an evaporation filter system that absorbs water in the water tank 22 by capillary phenomenon and humidifies the supplied air.

The air humidified by the evaporator 23 is transferred to the fan 24 through the air passage 40.

The fan 24 sucks air in the air passage 40 and blows air to the air chamber 41.

It can be seen that the fan 24 is located below the evaporator 23. Therefore, the position of the fan 24 in the forced evaporation type humidifier according to the present invention can be used not only in the upper part of the evaporator 23 but also in the lower part.

A heater (42) is provided below the fan (24).

The heater 42 can be installed at any position between the evaporator 23 and the air outlet 25 as well as below the fan 24,

If the heater 42 is installed between the evaporator 23 and the air outlet 25, the air cooled by the latent heat of evaporation can be hygienically heated without raising the temperature of the water tank and the evaporator. Further, if the air is excessively heated, it is dried. It is therefore appropriate to heat to a temperature that is comparable to the room average temperature.

The air that has undergone the humidification process and the heating process is discharged through the air outlet 25.

The embodiments of the present invention as described above are intended to illustrate the present invention and are not limited to the embodiments and drawings.
