Abstract

PROBLEM TO BE SOLVED: To eliminate shortcomings such that by a conventional hair dryer, air which is heated to a high temperature by a heater is blown to hair in order to dry wet hair, and the hair is damaged just like being burnt by the air of the high temperature. SOLUTION: By incorporating a reclaimable moisture absorbent rotor 1 or a moisture absorbent 6 inside, moisture-removed dry air being close to a normal temperature is created. By blowing the dry air to wet hair, the wet hair is quickly dried, and also, a shortcoming wherein the hair is damaged just like being burnt can be eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of drying hair near the normal temperature, which is created by utilizing the moisture absorbing action of a moisture absorbent rotor (1) or moisture absorbent (6) in order to dry wet hair. It is about the dryer.

[0002]

2. Description of the Related Art In a conventional hair dryer, in order to dry wet hair, air heated to a high temperature by a heater is blown out of the hair dryer by a fan and blown on the hair, thereby drying the wet hair. When the air is heated to a high temperature, the saturated vapor pressure increases, the relative humidity decreases, and in the flow of the high-temperature air, the evaporation of water is promoted, and the effect of drying the wet hair is obtained.
However, because high-temperature air is applied to the hair for a certain period of time, the hair is damaged by heat and burns, or the moisture required for the hair is taken away, causing the hair to be damaged and eventually leading to hair loss. It had a very serious drawback for it. However, in the past, there was no way to dry wet hair in a short time other than blowing air onto wet hair with high temperature, so heater-heated hair dryers that heat air to high temperature have been used. .

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to eliminate the drawback that the hair is damaged by heat and that hair loss is caused by using a hair dryer of a heater heating system. is there.

[0004]

SUMMARY OF THE INVENTION The moisture-absorbing hair dryer of the present invention according to the first aspect of the present invention creates dry air having a low relative humidity. It is characterized by using the chemical water vapor adsorption action of the agent rotor (1).
If the moisture in the air is chemically removed by the moisture absorbent,
Although there is a slight exothermic effect due to the chemical reaction, dry air at a much lower temperature and near normal temperature can be obtained as compared with the conventional method in which air is directly heated by a heater. By blowing this dry air near normal temperature on wet hair, it is possible to dry the hair in a short time, and by blowing air near normal temperature, the hair becomes hot and burnt. The disadvantage of being damaged can be eliminated. According to a second aspect of the present invention, in the moisture-absorbing hair dryer, the moisture absorbent rotor (1) is replaced with a moisture absorbent (6) having a detachable structure. The moisture-absorbing hair dryer of the present invention according to claim 3 is also one in which the above-mentioned moisture absorbent rotor (1) is replaced with a renewable moisture absorbent (6).

[0005]

Embodiments of the present invention will be described below. According to the first aspect of the present invention, as shown in FIG. 1, the air passage inside the hair dryer tube part (2) is divided into upper and lower parts by a partition wall (8), and the upper part is for regenerating the moisture absorbent. A regeneration air passage through which air flows is provided, and a lower stage is a dehumidification air passage which functions as an original hair dryer. The fan (4) is rotated by a motor (9) via a fan drive shaft (10), and serves to send air from the suction port (3) into the hair dryer tube (2). On the other hand, the motor (9) is driven by the reduction gear (11) and the hygroscopic rotor drive shaft (1).
It is also transmitted to the moisture absorbent rotor (1) via 2), and the moisture absorbent rotor (1) also turns. The air sent into the hair dryer tube (2) by the fan (4) is sent to the upper regeneration air passage and the lower dehumidification air passage by the partition (8). The air sent to the lower dehumidification air passage is
Dehumidified by passing through the hygroscopic rotor (1),
The air is blown out from the outlet (5) as dry air and blown onto the wet hair, thereby exhibiting the effect of drying the hair without increasing the temperature. On the other hand, the air sent to the upper regeneration air passage is heated to a high temperature by the moisture absorbent regeneration heater (7), and the wet portion of the moisture absorbent rotor (1) after adsorbing moisture in the lower dehumidification air passage. Turns and is sprayed where it appears in the upper passage. The wet portion of the moisture absorbent rotor (1) is heated by the high-temperature air to release moisture, and the moisture absorbing function is regenerated. Thereafter, the regenerated portion of the desiccant rotor (1) further turns to the lower dehumidification air passage again. The air that has passed through the moisture absorbent rotor (1) is discharged from the air outlet (13). Claim 1 is a moisture-absorbing hair dryer having the above-mentioned structure.
This is the described invention. In addition, if the speed of drying the wet hair is not sufficient with only the dry air blown out from the outlet (5), an auxiliary heater is provided in the lower dehumidifying air passage so that the hair is not damaged. The passing dry air may be slightly heated. The present invention according to claim 2 provides:
As shown in FIG. 2, the heater part of a normal heater heating type hair dryer is removed and replaced with a removable moisture absorbent (6). The air taken in from the inlet (3) by the fan (4) is dehumidified by passing through the desiccant (6), and the dry hair near room temperature is blown out from the outlet (5) so that the wet hair is not heated to a high temperature. Exhibits the effect of drying. If the speed of drying wet hair is not sufficient with only the dry air blown out from the outlet (5), an auxiliary heater is provided,
Dry air passing therethrough may be slightly heated as long as the hair is not damaged. According to the present invention, as shown in FIG. 3, a heater portion of a normal heater heating type hair dryer is used as a heater for regenerating a moisture absorbent (7), and a renewable moisture absorbent (7) is provided behind the heater (7). 6) is installed. When drying the hair, the heater (7) for regenerating the moisture absorbent is not operated, and the suction port (3) is operated by the fan (4).
The air taken in from the dehumidifier (6) is dehumidified by passing the air through the moisture absorbent (6), and the dry air near room temperature is blown out from the air outlet (5) to dry the wet hair without increasing the temperature. On the other hand, at the time of regenerating the desiccant, the heater for regenerating the desiccant is operated, and the sucked air is heated to a high temperature and blown to the desiccant (6) to regenerate the desiccant (6).

[0006]

According to the first aspect of the present invention, the hair is damaged by heating to a high temperature by using the moisture-absorbing hair dryer according to the first aspect of the present invention and blowing dry air at a temperature close to room temperature from the outlet (5) onto the wet hair. It can be dried quickly without any problems. The same effect as described above can be obtained by using the moisture-absorbing hair dryer according to claims 2 and 3 of the present invention.
