Abstract

PURPOSE:To prevent a nozzle attached to a blowout port from disturbing the non-contact measurement of a hair temperature by providing a control means for controlling a rotational range of the nozzle. CONSTITUTION:On the inside surface of both the left and the right sides of a blowout port 51 for blowing out hot air, a claw 55 is provided. A nozzle 5 which is connected to the blowout port 51 and in which the rear end side is a cylindrical shape, and also, the tip is a rectangular cylindrical shape is provided with a claw 56 in the upper and the lower parts of the rear end at the time when the longitudinal direction of the rectangular part of its tip side is set to the horizontal direction. In the case the nozzle 5 is attached so that the longitudinal direction of the rectangular part of its tip side becomes the horizontal direction, the claws 55, 56 do not interfere with each other. However, when the nozzle 5 is rotated, the claws 55, 56 abut on each other, therefore, the nozzle 5 cannot be rotated to a position in which the longitudinal direction of the rectangular part of the tip side becomes the vertical direction. Accordingly, the nozzle 5 is not positioned in the part which stands in the way of hair temperature measurement by a temperature measuring means 1 provided on the lower side of the part in which a heater 4 is contained in an air duct.

By the way, in a hair dryer, the nozzle 5 is attached to the outlet 51 when setting the hair, and the nozzle 5 is attached to the rear end of the outlet 51. While the side is cylindrical, the tip side is formed in a rectangular tube shape and is rotatably attached to the outlet 51,
The longitudinal direction of the rectangular tubular portion on the tip side can be changed.

For this reason, when the nozzle 5 is mounted and the longitudinal direction of the tip rectangular portion is the vertical direction as shown in FIG. 8, the tip of the nozzle 5 is located between the temperature measuring means 1 and the hair. Therefore, it becomes impossible to accurately measure the temperature of the hair by the temperature measuring means 1 in a non-contact temperature. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a hair dryer in which a nozzle attached to an outlet does not interfere with non-contact measurement of hair temperature.

DISCLOSURE OF THE INVENTION The present invention, therefore, provides a hair dryer provided with a temperature measuring means for measuring the temperature of hair in a non-contact manner and a nozzle detachably and rotatably attached to an outlet. The first feature is that the regulation means for regulating the rotation range of the nozzle is provided,
The second characteristic is that the temperature measuring means is arranged in the outlet, and the third aspect is that the nozzle is formed of a material that transmits radiant energy rays used for measurement in the temperature measuring means.
The fourth feature is that the interlocking device for moving the temperature measuring device in conjunction with the rotation of the nozzle is provided.

According to the first feature of the present invention, it is possible to prevent the nozzle from coming to a position which obstructs the temperature measurement by regulating the rotation of the nozzle, and the second feature is provided. For example, the nozzle does not enter the temperature measuring range of the temperature measuring means, and according to the third feature, the temperature measurement is not hindered even if the nozzle enters the measuring range of the temperature measuring means. According to the feature of No. 4, no matter where the nozzle is directed, the nozzle is not located at the place where it obstructs the temperature measurement by the temperature measuring means.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the illustrated embodiments. A fan 3 driven by a motor 2, a heater 4 for heating air blown by the fan 3, and a lower side of a portion of the wind tunnel in which the heater 4 is housed. As in the conventional example, the temperature measuring means 1 provided in the same is provided, but as shown in FIG. 55, 55 are provided. The nozzle 5 connected to the outlet 51 and having a cylindrical rear end and a rectangular tubular end has a rectangular tubular shape at the front end, and the nozzle 5 is moved vertically to the rear end side when the longitudinal direction of the rectangular portion is the horizontal direction. , Claws 56, 56. Reference numeral 52 in FIG. 2 is a suction port.

Further, as shown in FIG. 1, when the nozzle 5 is mounted so that the longitudinal direction of the tip end side rectangular portion thereof is the horizontal direction, the claws 55 and 56 do not interfere with each other, but the nozzle 5 When 5 is rotated, the claws 55 and 56 hit each other, so that the nozzle 5 cannot be rotated to a position where the longitudinal direction of the distal end side rectangular portion is the vertical direction, and therefore the hair temperature measured by the temperature measuring means 1 The nozzle 5 is not located in the place where it interferes with the measurement.

3 and 4, the temperature measuring means 1 is arranged inside the suction port 51 of the hair dryer and surrounded by the heater 4, and the measurement range of the temperature measuring means 1 is defined by the rectangular shape on the tip side of the nozzle 5. The range shown is smaller than the minor axis of the opening. In this case, no matter how the nozzle 5 is rotated, the nozzle 5 does not interfere with the temperature measurement of the temperature measuring means 1.

The nozzle 5 is made of a material that transmits radiant energy rays (infrared rays) used by the temperature measuring means 1 for measurement.
May be formed. In this case, as shown in FIG.
Even if the nozzle 5 is located between the temperature measuring means 1 and the object to be measured, the non-contact temperature measurement by the temperature measuring means 1 is not affected. In the embodiment shown in FIGS. 6 and 7, if the temperature measuring means 1 is attached to the outer surface of the nozzle 5 and the nozzle 5 is rotated, the temperature measuring means 1 also rotates and the nozzle 5 and the temperature measuring means 1 are connected. The relative positional relationship is always constant. Therefore, the nozzle 5 does not interfere with the temperature measurement by the temperature measuring means 1. Although the temperature measuring means 1 is attached to the nozzle 5 here, if the temperature measuring means 1 is made movable along the outer peripheral surface of the outlet 51 and the nozzle 5 is rotated, the The temperature measuring means 1 may also move along with the rotation.

[0012]

As described above, according to the present invention, the nozzle is not positioned or interferes with the place where the temperature measurement is obstructed, and therefore the temperature of the hair is not measured by the temperature measuring means. The contact temperature can always be measured accurately without being affected by the nozzle.
