2. Description of the Related Art Conventionally, a hair care device such as a hair dryer has been proposed that is provided with a humidifying mechanism so that air blown from an air outlet can be humidified (see, for example, Patent Document 1). In Patent Document 1, a steam generation tank is used as a means for generating humidified steam, and the steam generated in the steam generation tank is near the injection port of a blower channel (nozzle) through a guide chamber partitioned by a partition wall. To supply. A fan (blower) and an electric heater are arranged in the air passage, and hot air can be blown out from the injection port.
Japanese Utility Model Publication No. 51-42537

  However, in a conventional hair care device having a humidification function, the steam generation tank is heated by a dedicated heater that is different from the electric heater for generating hot air arranged in the air passage, and generates steam. . That is, the structure of the steam generating part is complicated by the amount of the dedicated heater provided in the steam generating tank.

  In addition, the steam generated in the steam generation tank is supplied to the air passage through the induction chamber, but since the back side of the induction chamber is a bag path, the steam introduced into the induction chamber is actively blown. I can't send it to the road. For this reason, there is a case where the air blown from the injection port cannot be efficiently humidified.

  Then, an object of this invention is to obtain the hair care apparatus which can humidify more efficiently while being able to simplify the structure of a vapor | steam generation | occurrence | production part.

In the first aspect of the present invention, the air passage extending from the air inlet to the air outlet is formed as a cylindrical outer cylinder , and the air that is installed in the air passage and sucked from the air inlet is the air. A fan that blows out from the air outlet, a heater that is installed on the downstream side of the fan in the air passage and that heats the air that passes through the air passage, and a heat-resistant cylindrical plate that is disposed on the outer periphery of the heater. In the hair care apparatus provided, a vapor generation unit that vaporizes a liquid by heat of the heater is disposed in the air passage, and the vapor generation unit includes a liquid tank that stores the liquid, and a liquid in the liquid tank. A vaporizing portion that contacts the heat receiving portion of the heater, and the vaporizing portion is brought into contact with the outer surface of the heat-resistant cylindrical plate heated by the heater, and between the heat-resistant cylindrical plate and the cylindrical outer shell. And air blowing Characterized by being arranged in the vicinity of.

In the invention of claim 2, the liquid tank is formed of a material having a heat transfer coefficient at 100 (° C.) of 200 (W / (m · K)) or more, and is disposed close to the heat receiving portion. It is characterized by.

  According to the first aspect of the present invention, since it is not necessary to provide a heater dedicated to the steam generation unit, the structure of the steam generation unit can be simplified, and thus the hair care device can be reduced in size and weight. Moreover, since the steam generating part is disposed in the air blowing path, the steam generated in the steam generating part can be carried on the air flow and smoothly carried to the air outlet, and the warm air blown from the air outlet can be more efficiently Can be humidified.

Moreover, while being able to simplify the structure of a steam generation part , a steam can be generated more efficiently and more reliably. Furthermore, it is possible to suppress the vaporization part from overheating and to generate steam more stably on the contact surface with the heat-resistant cylindrical plate.

According to the second aspect of the present invention, since the liquid tank is formed of a material having a high heat transfer rate and is disposed close to the heat receiving portion, heat can be efficiently transferred from the heat receiving portion of the heater to the liquid tank. Thereby, the liquid tank can be heated as a whole by the heat of the heater, and steam can be generated more efficiently.

  The outer periphery of the heater 6 is surrounded substantially concentrically with the cylindrical outer shell 4 by a heat-resistant cylindrical plate 6 c having a smaller diameter than the cylindrical outer shell 4. Therefore, the air flow AF is divided into a flow passing through the inside of the heat-resistant cylindrical plate 6c and a flow passing outside the heat-resistant cylindrical plate 6c, that is, between the heat-resistant cylindrical plate 6c and the cylindrical outer shell 4. The
