Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recirculation hair dryer, and more particularly to a recirculation method comprising a suction and discharge mechanism for a hair dryer.

The hair dryer referred to in the present invention is not a no-end type hair dryer, but a hair dryer that is used for permanent setting, which is mainly used for commercial purposes such as beauty salons. This refers to a type of hot air dryer, such as a hood type, that is worn over the head to dry the hair.

This type of hair dryer is a blower type that only blows air,
There are three types of hair dryers: the agitation type, which uses discharged air for agitation, and the recirculation type, which circulates and sucks the discharged hot air. From the point of view of energy saving, the last type of reflux hair dryer is ideal, and the reflux method of the present invention relates to this type.

Although there are few prior art related to recirculation hair dryers, Utility Model Publication No. 16954/1983 is a typical one. However, in this recirculation type, concave grooves are radially provided at the top of the inner surface of the hood, and hot air is sucked through the grooves. It is certainly desirable to take into consideration the fact that the suction air is dispersed and inhaled without being concentrated in one place, but providing a concave groove inside the hood also poses difficulties in the molding process. There was also the drawback of stability.

The present invention was created in view of cost considerations. The actual flow will be explained below based on the drawings.

(1) is a hemispherical hood, and this hood has an inner hood (
2) and an outer hood (3), and a mortar (4) is built into the upper part between the inner and outer hoods (21+31).The hood of the present invention Since it has a double structure as described above, air is transported through the interior thereof.

There are many circular holes (5) on the entire surface of the inner hood (2).
・(5) are scattered and drilled. Also, the outer hood (3
) has a ring-shaped bottom (6) projecting inward, and the bottom edge of the inner hood (2) is placed on the bottom (6). However, near the lower edge of the outer hood (3) there is an inner flange (71 (71f7+ +71) protruding in all directions, and near the lower edge of the inner foot 2) there is a ring-shaped outer flange that protrudes outward. (8) protrudes, and the inner tsuba (7+ +71 +71 +
71 (9+ +91 +91
+91 is drilled. Therefore, the inner flange (71+71 +71) of the outer hood (3) (71 and the notch (91+91 f9) of the inner hood (2)) Since it is locked to the outer flange (8) of the inner hood (2), the lower edge of the C hood (2) is connected to the bottom part (6) and the inner flange (7) (71+).
71 +71 and is fitted with the outer hood (3), so it will not come off in either the up or down direction.

However, unlike in Figure 2, the lowermost edge of the inner hood (2) has slit holes (1 (10) GOI +I (lI is drilled. Therefore, the outlet is a circular hole (5)...
(5) and slit holes (1) (10) flα (11), and hot air is discharged from these outlets.

An outer suction port 01) is provided at the top of the one-sided hood (3), and an inner suction port 02 is provided at the top of the inner hood (2). Therefore, when the motor (4) is operated, fresh air flows from the external suction port (11).
In addition, the hot air used for drying is circulated and sucked from the inner suction port α2, and both types of air join together and are transferred inside the double-structured hood in the direction of the arrow in Fig. 1. It is discharged from the outlet.

The recirculation method of the present invention uses the discharged air (more specifically, hot air).
However, since the hot air contains moisture and is unstable depending on the degree of dryness, the amount of suction should be limited to a portion of the total amount of air sucked. In the case of this embodiment, as a preferable example, the total suction air amount is within 4 to 1
The amount of suction is adjusted so that the amount of air of 4 is sucked from the inner suction port, and the fresh air from the inside of Tachibana is sucked from the outside suction port based on the remaining air amount. Although the details of this adjustment are not shown, it is performed by the size of each suction port, a filter, and a suction amount adjustment plate. If the amount of air that is recycled and used is more than enough, the amount of air will be insufficient and the heat and humidity will be too high. Further, if the amount of recirculated air is set to be less than ζ, the energy saving effect aimed at by the present invention cannot be sufficiently achieved.

The reflux method of the hair dryer of the present invention is based on the method described in the above embodiment, and its effects and effects are as follows.

Since the used hot air is effectively recirculated, it can contribute to energy saving. In addition, the ratio of reduced hot air to fresh air was set in advance, and the discharged air was stabilized at the optimum value. A slit-shaped discharge hole is also provided at the lower edge of the inner hood to ensure more even drying. Furthermore, by avoiding grooves or other concave shapes on the inner surface of the inner hood,
It is designed so that it can be used and operated without any problems.
