Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a humidifier suitable for maintaining an appropriate indoor humidity of a vehicle.

[Conventional technology]

Continuous heating of the interior of a vehicle causes the interior to become excessively dry and the interior humidity to decrease. This causes discomfort to the driver and passengers. To prevent this, various humidifiers have been used in the past. For example, the system shown in Utility Model Application No. 56-83416 uses ultrasonic vibrations to forcibly create water droplets and blow them into the room. In addition, Utility Model Application No. 56-21213 brings air into contact with a cotton cloth soaked in water and sends this air into the room.
No. 185618 collects water generated in the evaporator of an automobile air conditioner into a container and blows it out in the form of mist using high-speed airflow. The sponge is brought into contact with air to prevent the air from drying out.

[Problem that the invention attempts to solve]

In the above-mentioned conventional technology, when using ultrasonic vibration, water droplets and particles are forcibly introduced, resulting in excessive indoor humidity, moisture condensation occurs when heating is stopped or cooling, and problems such as water accumulation in the room occur. .
In addition, since all of the above-mentioned conventional technologies are provided with a water tank or a water reservoir, there is a problem in that the interior of the room is flooded with water if the tank falls over. Moreover, the structure of each of them is complicated, resulting in a problem of high cost.

The present invention solves the above-mentioned problems, and aims to provide a humidifier that can provide a suitable indoor humidity, does not spill water, has a simple structure, and can be implemented at low cost.

[Effect]

When the air introduced into the water-absorbing polymer container comes into contact with the container, the humidity of the air increases, and the air having an appropriate humidity is returned to the room.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in FIG. 1, an air outlet 5 and an air inlet 6 are formed in the upper lid 3 of the closed container 2. As shown in FIG. Top lid 3
A heater 200 is provided at the bottom of the case to which it is attached. The heater has respective sensors 202 and 20 that detect indoor temperature and humidity.
3. Heater activated by the sensor ON-
An OFF switch 201 is provided. A powdery water-absorbing polymer material 1 is inside the case 4 to which the top cover 3 is attached.
is filled in an appropriate amount. The water-absorbing polymer material 1 has the property of absorbing injected water and keeping it in a wet state, and also evaporates water in proportion to the relative temperature difference with the surroundings (hereinafter, water-absorbing polymer material containing water) Material 1 is referred to as water-absorbing polymer 1A).

An air introduction pipe 7 and an air pipe 8 are connected to the air introduction port 6. Further, an air supply source 10 for introducing air through a valve 9 is connected to the air pipe 8 . In this embodiment, the air introduction pipe 7 includes a central pipe 7a, an annular pipe 7b surrounding the central pipe 7a, and a central pipe 7.
a and a connecting pipe 7c that connects the annular pipe 7b, and each pipe is provided with a large number of through holes 11. As the air for the air supply source 10, indoor air, air branched from a vehicle heater, or air from a dedicated air pump is used. A partition plate 12 provided in the case 4 prevents the water-absorbing polymer 1A from dissipating, and is disposed above the water-absorbing polymer 1A. In addition, the partition plate 12 has through holes 1
3 is drilled.

Next, the operation of this embodiment will be explained in more detail.

First, the top cover 3 is removed and water is poured into the case 4. Water is absorbed by the water-absorbing polymer material 1, causing the material to expand as a whole. A mark 14 is provided inside the case 4, and a partition plate 12 on the expanded water-absorbing polymer 1A
When the water reaches the position of the mark 14, water injection is stopped.

As mentioned above, the water-absorbing polymer 1A is placed in a sealed container 2.
Internal humidity and surrounding outside air (e.g. inside a vehicle)
It is maintained in a state in which water has evaporated in proportion to the relative humidity difference. After closing the upper lid 3, when indoor air, etc. is introduced from the air pipe 8 into the air introduction pipe 7, the introduced air flows through the through hole 11 into the water-absorbing polymer 1A.
Go within and make contact with this. At this time, the moisture that has evaporated is absorbed, improving humidity. When the humidity is insufficient, the temperature sensor 202 and humidity sensor 203 turn on the heater ON-OFF switch 201 of the heater (electric heater) to heat the water-absorbing polymer 1A to increase evaporated water and improve the humidity. As expected. Air with appropriate humidity is separated from the partition plate 12.
through the through hole 13 of the air outlet 5 of the upper lid 3.
Water is discharged from the tank and returned to the interior of the vehicle. The reduced air is sent into the closed container 2 again and is saturated with no relative humidity difference.

As described above, the indoor air has an appropriate humidity, and does not cause discomfort to the driver and passengers. On the other hand, since the injected water is absorbed by the water-absorbing polymer material 1, even if the closed container 2 falls over, water will not spill. Furthermore, in this embodiment, the airtight container 2
A suitable amount of water-absorbing polymer 1A is housed inside, and the structure is simple and can be formed at low cost.

FIG. 2 shows another embodiment of the invention.

In the above embodiment, indoor air was forcibly introduced into the closed container 2, but in this embodiment, a natural evaporation method is used.

Closed volume 2 formed from a rectangular box shape
Case 4A of A is equipped with a heater at the bottom.
A water-absorbing polymer 100A is stored. The water-absorbing polymer 100A is formed by storing granular water-absorbing polymer materials 100 in cases 15 arranged in a comb-like manner with appropriate gaps, and pouring an appropriate amount of water into the case 15 to absorb water. Although not clearly shown in the figure, the individual water-absorbing polymers 100A arranged in a comb shape are formed to have an appropriate surface area in the direction perpendicular to the plane of the paper.
In addition, a large number of through holes 16 are bored in the case 15 in order to bring the water-absorbing polymer 100A into contact with the introduced air. Upper lid 3A attached to case 4A
An air discharge port 5A and an air introduction port 6A (these are used in combination) are formed through the hole. In addition, through holes 13 are also provided in the partition plate 12A mounted on the case 15.
A is drilled.

With the above structure, the outside air around the airtight container 2A comes into contact with the moisture evaporated from the water-absorbing polymer 100A through the air inlet 6A and the through hole 13A, and is maintained at an appropriate humidity.
is returned to the outside air. When the humidity is insufficient, the temperature sensor 202 and humidity sensor 203 turn on the heater (electric heater).
In the present embodiment, in which the OFF switch 201 is turned on and the water-absorbing polymer is heated to increase evaporated water and raise the humidity, the same effect as in the above-mentioned embodiment can be achieved.

Note that the heater may be an electric heater, engine cooling water, or the like.

[Effect of idea]

As is clear from the above explanation, according to the present invention, the humidity of the indoor air can be maintained at an appropriate level, giving a pleasant feeling to passengers, etc., and there is no fear of water spillage, and it can be implemented easily and inexpensively. .
