Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a dryer that blows out dry hot air by utilizing the moisture adsorption/desorption reaction of a desiccant.

Conventional technology Conventionally, as shown in Fig. 3, a dryer has a method in which a fan 31 and a heater 32 are installed inside an outer shell 3o, and outside air is introduced by the fan, heated by the heater, and hot air is blown out. there were. In addition, cold air was generated by simply turning off the power to the heater and blowing outside air at room temperature using a fan.

Problems to be Solved by the Invention In this case, for drying purposes, the higher the amount of heat and the more airflow, the faster the drying time, but if the hot air hits the scalp, it may be uncomfortable, or if the temperature is still below 13°C. If it exceeded the limit, there was a risk of deteriorating the quality of the hair. Therefore, it was necessary to keep the temperature at 80° C. or less, which was not too high, and in this case, the drying time became longer. There was also the problem that increasing the wind speed to speed up drying resulted in increased noise.

Further, even though the cold air operation is called cold air, it is room temperature air, and a temperature lower than room temperature cannot be obtained, so the cooling effect is insufficient.

In view of the above-mentioned conventional problems, the present invention provides an apparatus that can shorten drying time even with hot air at a temperature that does not damage hair.

Further, the present invention provides a device that enhances the cooling effect by blowing cooling air at a temperature lower than room temperature during cold air operation.

Means for Solving the Problems In order to solve the above problems, the present invention provides a method for air circulation by connecting a reaction container filled with a desiccant and a storage container filled with a water-absorbing substance through two or more connecting pipes. -7 A structure that allows a ring is provided, and a ventilation passage is provided at both ends of the reaction vessel, one leading to an air inlet and the other to an air outlet, and a heater is installed in the ventilation passage leading to the air outlet, The air that enters through the air inlet is passed through a desiccant, dried, and then heated by a heater to an appropriate temperature before being blown out through the air outlet.

Further, in addition to the above configuration, the present invention provides a ventilation circuit including a storage container inside, connects the ventilation circuit to an air inlet and an air outlet, and further seals the reaction container, the storage container, and a direct connection pipe. When the circuit is purchased and the moisture in the closed circuit is adsorbed by the desiccant, the moisture contained in the water-absorbing substance evaporates.
At that time, the storage container cooled by the latent heat of vaporization is brought into contact with the air in the ventilation circuit and cooled, and the cooled air is blown out from the air outlet.

For production The effects of the above means are as follows.

Since the present invention uses a desiccant to remove moisture from the air for drying, the drying time can be shortened by 6 vanes even if the blowing air temperature is low. In addition, the present invention is capable of absorbing heat due to evaporation of water (
Since the suction air can be cooled by the cooling section, it is possible to obtain blowout air that is lower than room temperature.

Example Embodiments of the present invention will be described below with reference to the drawings.

First, a first embodiment of the present invention will be described with reference to FIG.

In the figure, 1 is a reaction vessel filled with zeolite 2, which is a desiccant that adsorbs water, and the zeolite layer 2 is held at both ends by wire mesh 3, and a heater 4 and a cooling pipe 5 are installed inside the zeolite layer. inserted independently. This zeolite layer 2 is filled with voids that allow air to circulate. 6 is perlite 7, which is a water-absorbing substance that absorbs water.
The pearlite layer 7 is covered with wire mesh 3 at both ends.
A cooling pipe 8 is inserted inside the pearlite layer, and fins 9 are formed on the outer periphery.

7 ・＼-7 The reaction vessel 1 and the storage vessel 6 are connected by connecting pipes 10 and 11 in the upper connecting pipe 10, and the upper connecting pipe 10 has a blower fan 12 and an opening/closing unit 13, and the lower connecting pipe 11 has an opening/closing unit. A valve 14 is attached.

Ventilation channels 15 and 16 are connected to both ends of the reaction vessel, and can be opened and closed by on-off valves 17 and 18, respectively.

On the other hand, a ventilation passage 19 is provided around the storage container 6, and the ventilation passage 19 is connected to the ventilation passage 15 at the upper part, and the ventilation passage switching valve 20
It is connected to the air outlet [1m+21] through. Also,
The ventilation passage 19 is connected to the ventilation passage 16 at the lower part, and is connected to the suction port 23 via the ventilation switching valve 22.

is attached.

The operation in the above configuration will be explained next.

First, a state in which the zeolite layer 2 is adsorbing water is considered as a starting point. When the on-off valves ↑17 and 18 are closed to shut off the reaction vessel 1 and the ventilation passages 15 and 16, and the on-off valves 13 and 14 are opened, the reaction vessel 1 and the storage vessel 6 form a closed circuit. In this state, when the zeolite layer 2 is heated to 150° C. or higher by the heater 4, water is desorbed from the zeolite layer. When the fan 12 is operated, the moisture (steam) moves, and when passing through the perphite layer 7 cooled by the cooling water pipe 8, the moisture condenses and is absorbed by the pallite. When the on-off valves 13 and 14 are closed after the desorption reaction of water from the zeolite layer 2 is completed, the reaction vessel 1 is kept in a dry zeolite layer state, and the storage container 6 is kept in a water-absorbed pearlite layer state. Next, the zeolite layer is cooled by the cooling water pipe 5. The drying/cooling device of the present invention is maintained in this state when not in use. From this state, dry air or cooling air can be taken out by the following operation.

Dry air is suspended as follows.

For use 1 Samurai, open the on-off valves 16 and 17, and set the ventilation passage switching buttons ↑20 and 22 so that the outlet 21 and the ventilation passage 16 are connected 9I\-/, and the suction port 23 and the ventilation passage 16 are connected. Set to . Then, when the fan 24 is operated and the heater 25 is energized, the air entering from the suction port 23 passes through the zeolite layer 2 to remove moisture, and then the heater 2
5 and is blown out from the outlet 21. If the temperature of the zeolite layer increases due to adsorption of water, the adsorption capacity decreases, so it is desirable that the temperature increase of the zeolite layer is suppressed by the cooling pipe 5.

Cooling air is taken out as follows.

In use, the ventilation passage switching valves 20.22 are set so that the ventilation passage 19 is connected to the air outlet 21 and the suction opening 23. Then, when the on-off valves 13 and 14 are opened and the 77-unit 12 is operated, air circulates through the reaction vessel 1 and the storage vessel 6, and moisture in the air is adsorbed by the zeolite layer 2, while water from the pearlite layer 7 is Water evaporates. Therefore, the storage container 6 is cooled by the latent heat of vaporization. When the fan 24 is operated,
The air entering from the suction port 23 is cooled by passing through the fins 6 of the storage container, and then the air is cooled by passing through the fins 6 of the storage container.
/ Blowing d3 from mouth 21.

After taking out dry air or cooling air, the zeolite layer is still adsorbing moisture, so the on-off valve 1
7.18 is closed, and the operation of desorbing water from the zeolite layer 2 and making the pearlite layer 7 absorb water as described above is performed. At that time, if the water retained in the pearlite layer becomes excessive and drips into the lower part of the storage container 6, a drain passage (not shown) is installed at the bottom of the storage container.
drain to the outside.

As described above, dry air or cooled air can be obtained.

Next, a second embodiment of the present invention will be described with reference to FIG.

In the figure, 1 is a reaction vessel filled with zeolite 2, which is a desiccant that adsorbs water, and the zeolite layer 2 is held at both ends with a wire mesh 3. Inside the zeolite layer, a heater 4 and a cooling vibro are installed independently. It has been inserted. This zeolite layer 2 is filled with voids that allow air flow Jm. 6 is a storage container that has a cooling water pipe 8 inside, and can store condensed water 26 at the bottom, and also has a faucet 27 for discharging this condensed water 26 to the outside as necessary. It is a provision.

The reaction container 1 and the storage container 6 are connected to a connecting pipe 1 above and below.
0.11, the upper connecting pipe 1° has a blower fan 12 and the on-off valve 13, and the lower connecting pipe 11 has the on-off valve 1.
4 is attached. A blowout port 21 and a suction port 23 are connected to both ends of the reaction vessel 1, and an on-off valve 17.
18 enables opening and closing. A fan 24 for blowing dry air from the device and a heater 26 for heating the air to an appropriate temperature are attached to the air outlet 21.

The operation in the above configuration will be explained next.

First, a state in which the zeolite layer 2 is adsorbing water is considered as a starting point. The on-off valves 17.18 are closed to shut off the reaction vessel 1, the blow-off port 21, and the suction port 23, and the on-off valves 13.1 are closed.
When 4 is opened, reaction vessel 1 and storage vessel 6 constitute a closed circuit. In this state, when the zeolite layer 2 is heated to 150° C. or higher using the heater 4, water is desorbed from the zeolite layer. When the fan 12 is operated, the moisture (steam) moves, is cooled by the cooling water pipe 8, condenses, and accumulates in the lower part as condensed water 26.

When the on-off valves 13 and 14 are closed after the desorption reaction of water from the zeolite layer 2 is completed, the reaction vessel 1 can maintain the state of a dry zeolite layer. Thereafter, the zeolite layer is cooled by the cooling water pipe 5. On the other hand, the condensed water 26 in the storage container is discharged to the outside by opening the faucet 27, and the faucet is closed after draining. From this state, dry air can be taken out by operating the lower part.

During use, when the on-off valves 17 and 18 are opened, the fan 24 is operated, and the heater 25 is energized, the air entering from the suction port 23 passes through the zeolite layer 2 to remove moisture, and then is heated by the heater 25. It is heated and blown out from the outlet 21. If the temperature of the zeolite layer rises due to adsorption of water, the adsorption capacity will drop, so it is desirable to suppress the temperature rise of the zeolite layer by vibrocooling water.

After the dry air extraction operation, the zeolite layer is adsorbing moisture, so the on-off valves 17 and 18 are closed to desorb moisture from the zeolite layer and store it in the storage container. Perform an operation to condense and drain water.

Dry air can be obtained in the above manner.

In the above embodiments, zeolite was used as the desiccant and perlite was used as the water-absorbing substance, but in addition to these, silica gel, activated carbon, or activated carbon impregnated with lithium chloride can be used as the desiccant. Further, as the water-absorbing material, various types of fibers and porous plastic materials that do not cause chemical reactions with water can be used.

In particular, in the apparatus of the present invention, a fan is provided in the circuit connecting the reaction vessel and the storage vessel to cause air circulation. If this fan is 14 pages long, air circulation is limited to convection due to temperature differences, so
The amount of air circulation is small, and the adsorption/desorption reaction progresses slowly.

Effects of the Invention As is clear from the above embodiments, the present invention can blow dry warm air by heating the air after drying it, so even if the blowing temperature is low, the drying time can be shortened. When used for hair drying, deterioration of hair quality can be suppressed. Furthermore, by switching the ventilation circuit, it is possible to blow air that is cooler than room temperature, so when applying makeup, the hands and face are cooled with the cooled air, and when using cosmetics, a smooth feeling can be obtained.
