The present invention relates to a humidifying device for moving steam from the humidifier. Plants and microorganisms
As a humidifier for indoor growth and storage of food in dry areas
Available. [0002] 2. Description of the Related Art Conventionally, as a humidifier, ultrasonic waves are used from water.
There is a known device that generates water vapor using
ing. In this conventional humidifier, an ultrasonic device
Required, which is expensive and to some extent
Running power is required because of the use of
In addition, there is a problem that water supply is required. [0003] SUMMARY OF THE INVENTION
Challenges are small, very low power and long-term
It can be operated continuously, running cost is extremely low, and it is empty
Since it takes in water vapor in the air,
It is to provide a wetting device. [0004] [Means for Solving the Problems] A book that has solved the above problems
The structure of the invention is 1) Humidifying equipment / box or first space in room and water vapor
Communicates with the second space where
Water-repellent, waterproof and breathable
Truncated circle so that the water-repellent surface is on the second space side
Provided in the shape of a cone, the passage is divided annularly by the moisture-permeable membrane,
A plurality of air chambers are formed, and the air in the small room is cooled down in accordance with the first space side.
A Peltier element that gives a temperature gradient so that
Working at a time when the temperature is higher than the temperature of the second space
So that the Peltier element heats and cools.
Provide a grounded conductive porous body near the moisture permeable membrane in the room.
And the same conductivity as the heating and cooling surfaces of the Peltier element.
The holes are thermally connected to each other via heat conductors, and
The product of the air permeability and the moisture permeability of the plurality of moisture permeable membranes is the permeability of the first space side.
The humidifier is designed to be larger as a wet film.
The term “air permeability” in this specification refers to the air permeability of the JIS term.
And [0005] [Function] The reason why a plurality of small chambers are provided in the ventilation path is that
By partitioning into space, the temperature and pressure of this partitioned space
Conditions can be easily adjusted to the conditions required for water vapor transfer control
Water vapor due to the difference in temperature and pressure between the two spaces
The purpose is to increase the sensitivity of movement. Even smaller Peltier elements
The temperature difference due to heating and cooling by
To be The temperature difference between the chambers due to the Peltier element is
A temperature difference at which dew condensation hardly occurs is, for example, about 2 to 5 ° C. Book
In the present invention, the surface of the moisture permeable membrane on the second space side is made water repellent.
You. This allows the water condensed on the water-repellent surface to be water-repellent and water-repellent
Vertically downward in the second space side by peeling off from the surface
To enter the first space through the moisture permeable membrane.
To prevent. Furthermore, the water-repellent surface is relatively negatively charged,
To attach Na of NaCl to prevent intrusion of NaCl
This is effective in reducing salt damage. Also, a conductive porous body is provided separately from the moisture permeable membrane.
Therefore, grounding is performed on the outer wall of the small chamber,
The effect of the moisture retaining dielectric on the wall material affects the transport speed of water vapor
The purpose is to prevent the impact. Also, conductive porous material
Suppresses the electrification of the moisture permeable membrane and prevents the moisture permeability of the moisture permeable membrane from decreasing.
Go. This causes abnormal charging when the movement of water vapor is large.
To prevent convection when the movement is small.
You. Another function of the conductive porous material is the heat generated by the Peltier device.
Or it becomes a good conductor of heat transfer for cooling, and controls the temperature of the small chamber
To facilitate. One of the adjacent small chambers by a Peltier element
Is heated through the conductive porous body, and the other conductive porous body is heated.
The other compartment is cooled through the
Arrangement). As a result, the steam
Try to move lower. Therefore, water vapor transfer at temperature
Strengthen direction. In addition, temperature control of small chambers and porous
Control the points to ensure the direction of water vapor movement. in this way
Controlling the temperature and pressure of a small chamber with a Peltier element
Increases the direction of water vapor transfer. Or in the opposite direction of steam
Inhibits movement and maintains direction. And transparent
The conductive porous body of the wet membrane prevents the electrification of water vapor,
Transfer due to static electricity due to the dielectric on the wall of the airway and ventilation passage
Prevents the direction of motion from being disturbed, and removes water vapor from one space to the other.
To be able to move smoothly into the space. [0008] The reason why the moisture permeable membrane of the present invention is a cone.
Will be described. Control of natural convection by reducing or expanding the volume
And the unit surface in the direction of the transfer of the held thermal energy
Control of the probability of loss per product, as well as heat
Combines three types of control utilizing differences in conduction speed
The energy gradient in the direction of travel
Utilizes the physical properties of the constituent materials to achieve the natural heat conduction rate
You have to do something to make it harmony. Therefore, heat energy
The inconsistency of the direction of movement of the lug gradient is the combination of heat transfer and insulation
Basically, it can be solved by combination. This function
An auxiliary measure to satisfy the staff is the area of the cell surface
Is a combination of For this purpose, a conical or nearly trapezoidal
It can also be applied to form chambers with surfaces
You. The reason for this is, for example,
Are made of the same heat conductive material.
In this case, heat transfer is performed in proportion to the length.
Adjust the temperature gradient of the location using this length variable
can do. This is based on the assumption of very low current consumption.
In the case of this device, it is a very important matter and heat insulation
Do not use materials, and use materials with high heat conduction speed.
This is a particularly effective means when it is used. Even in area, circle
By using a conical shape, it is possible to compare
Large area is secured, and therefore mobile water vapor
Also increases dramatically. Also, if the surface area increases
Is released from the surface by radiation or heat of vaporization
The energy loss is proportional to the surface area. Therefore, the length
If it increases, the heat transfer rate is proportional to the heat transfer rate, so the heat transfer rate is slow
On the other hand, the surface area increases as the length increases
Increases the loss.
Between the heat transfer and the heat loss
different. Therefore, the conduction efficiency in the longitudinal direction is conversely
Since the rate of increase is smaller for a cone,
Therefore, the cone has a smaller conduction velocity loss rate per unit.
And The minimum value of the surface area is
Is obtained when the heights are equal to each other.
Is obtained when it is 1.73 times the square root of 3
(See FIG. 19). Adjust the heat conduction speed like this
As a means, a device configuration that satisfies the relationship between length and surface area is used.
Just do it. Furthermore, the vapor-permeable membrane that partitions the compartment is frustoconical
And a frustoconical shape so that it can be
If it is possible to form a small chamber compactly
Both are conical small chamber spaces, and the surface relative to the volume
Heat transfer is reduced by increasing the product, and the water vapor transfer method
Directivity can be made efficient. The moisture permeable membrane will be described in more detail. FIG.

FIG. This means that the inside of the porous part inside the membrane is physically saturated.
Alternatively, it indicates the comparative temperature when the dew point is reached.

A need arises to provide such a fin configuration. Above hand
The steps are based on the analysis results of the basic morphological model of this device.
When the discharge from the outside air and the backflow phenomenon are considered.

If you are trying to dehumidify
The following conditions are required as a function of. The second space
In the case of the first space where the temperature fluctuation is small,
Since the movement in the direction of the first space occurs,
The movement is from the side small chamber to the first space side small chamber. This is the membrane
It depends on the difference between moisture permeability and air permeability. That is, the moisture permeability gradient
Is smaller from the second space side toward the first space side
Therefore, water vapor easily penetrates, but since the air permeability is the reciprocal,
To compare the amount of movement, evaluate by moisture permeability × air permeability
I do. This product is from the second space side toward the first space side
Because the water vapor can be present

This treatment is performed in the direction in which the film surface can be seen. That is, clogging
Compression reduces the porosity of the membrane surface
Changes its heat of vaporization and changes its color.
It is easy to understand. [0021] As described above, according to the present invention, the passage of the moisture permeable membrane is achieved.
The value of the product of the porosity and the moisture permeable membrane depends on the direction in which the water vapor moves.
With a water-repellent surface under the moisture-permeable membrane, and
Of water vapor by using porous porous material and Peltier device
Gives strong direction and can be humidified with minute power
It was assumed. It can be manufactured inexpensively with no moving parts,
In addition, the running cost was extremely low.
