Description

Far-infrared ray hair dryer {Far-infrared ray hair dryer}

The present invention relates to a hair dryer that emits far-infrared rays, and more particularly, by applying a sintering composition to the surface of the bobbin and sintering it, the radiation efficiency of far-infrared rays is maximized, shortening the hair drying time, providing shine to the hair, and activating the scalp. It relates to a hair dryer that emits far-infrared rays, which are effective for preventing hair loss through.

In general, a hair dryer is a household appliance tool used to dry or clean wet hair. The heat from the heating part is sent to the hair by a fan to dry the wet hair through hot air or use the desired hairstyle. It is used when setting.

Far-infrared rays have a wavelength of 8-20㎛, which is the most beneficial to the human body, and the most powerful feature of far-infrared rays is the ability to penetrate deep into the human body.At this time, it is radiated to water and protein molecules that make up the cells of the human body with minute vibrations of about 2,000 times per minute. It resonates to increase cell activity, strengthens metabolism, increases tissue regeneration, and promotes blood circulation.

However, the far-infrared ray dryers currently on the market adopt a method in which a far-infrared ray lamp or simply a ceramic material is applied to the internal parts of the dryer, but most of them only emit visible or near-infrared rays, and there is hardly any far-infrared rays. Even if it is radiated, it is not an exaggeration to say that the radiated energy is small.

Hereinafter, a preferred embodiment of the present invention will be described in detail.

In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, a detailed description thereof will be omitted. In addition, terms to be described later are terms defined in consideration of functions in the present invention, which may vary according to intentions or precedents of users or operators. Therefore, the definition should be made based on the contents throughout this specification.

1 and 2 are perspective and exploded perspective views, respectively, of a hair dryer emitting far infrared rays according to the present invention.

1 and 2, the hair dryer 10 for emitting far-infrared rays according to the present invention includes a frame 11 having a certain internal space formed therein and an outlet 11a through which heated air is discharged. , A bobbin 13 installed in the inner space of the frame 11 and having a sintered layer 13c emitting far-infrared rays formed thereon, and a hot wire (not shown) wound around the bobbin 13.

In the present invention, the main technical feature is that the sintered layer formed on the surface of the bobbin emits far infrared rays when heat is generated by the heating wire.

On the other hand, the bobbin 13 is made of a season insulating material such as mica because it must have electrical insulation because the heat wire is wound and heat resistance to heat generated from the heat wire.

The bobbin 13 of the present invention may be composed of two plates 13a having a cutout groove 13b, and it is exemplified that each cutout 13b is inserted into each other to form a'┼'-shaped cross section. I can.

A sintered layer may be formed after assembling the bobbin, but in the present invention, a sintered layer is first formed on the surface of each plate, and then two plates are assembled to produce a bobbin having a sintered layer.

The sintered layer may be formed by applying a sintering composition to the surface of each plate constituting the bobbin, followed by heat treatment.

The sintering composition may be exemplified by mixing the first powder for glassy glaze, the second powder for far-infrared emission, and water.

The first powder for the glassy glaze may exemplify that it contains at least one of silicate, feldspar, and limestone. Silica is the main component of glassy glaze, feldspar plays a role as a flux, and limestone plays a role in affecting the surface gloss.

The second powder for emitting far-infrared rays may exemplify that at least one of kaolin, bentonite, zeolite, sericite, and serpentine is selected.

In the sintered layer, the first powder for glassy glaze, the second powder for far-infrared emission, and the sintering composition of water are added to a ball mill device, and then the first powder and the second powder have a uniform average particle size. Crush them together Here, it can be illustrated that the average particle size of the powder in the sintering composition is 0.1 to 10 μm.

Then, a paste-like composition for sintering is applied to the surface of a plate constituting a bobbin, dried first, and then sintered secondarily to form a sintered layer.

Here, the primary drying of the sintering composition may be performed at 150±20° C. for 10±3 minutes.

The secondary sintering is preferably performed at 550 to 800° C. for 30 seconds to 5 minutes. For example, when sintering at a temperature of less than 550°C for less than 30 seconds, the adhesion to the plate containing mica as the main component decreases and the sintered layer is easily detached, and when the temperature exceeds 800°C for more than 5 minutes, the adhesion is excellent. Since the strength of the plate containing one mica as a main component is significantly lowered and is easily broken, it is preferable to limit it to the above-described range.

In particular, when the secondary sintering is performed at 550 to 800° C. for 30 seconds to 5 minutes, far-infrared emission performance is greatly improved in the operating temperature range of the hair dryer, which will be described later.

Hereinafter, a preferred embodiment of forming a sintered layer in the hair dryer emitting far infrared rays of the present invention will be described in more detail.

A bobbin assembly plate containing mica as a main component is prepared (see Fig. 1a).

Silica, feldspar, and limestone are mixed in a weight ratio of 1:0.4:0.1 to prepare the first powder for glassy glaze.

Kaolin, bentonite, zeolite, serpentine, and serpentine are mixed in a weight ratio of 1: 0.3: 0.3: 0.2: 0.1 to prepare a second powder for emitting far infrared rays.

Based on 100 parts by weight of the first powder, 50 parts by weight of the second powder and 110 parts by weight of water are placed in a ball mill and pulverized to prepare a composition for sintering.

The sintering composition is applied to the surface of the bobbin assembly plate, and then put in an oven and dried at 160° C. for 10 minutes (see Fig. 1b).

The dried plate was put in a sintering furnace and sintered at 680° C. for 1 minute to complete the formation of the sintered layer (see FIG. 1c).

A sintered layer was formed in the same manner as in Example 1, except that the sintering temperature was 710°C and the sintering time was 2 minutes in Example 1.

In Example 1, a sintering layer was formed in the same manner as in Example 1, except that the sintering temperature was 740°C and the sintering time was 3 minutes.

The results of measuring the far-infrared emissivity and radiation energy by varying the temperature of the specimens for Examples 1 to 3 and the control specimen that was not sintered after performing only the drying process in FIG. 1B are shown in Table 1 below. The far-infrared ray measurement test was performed by requesting the Korea Far-Infrared Application Evaluation Research Institute.

As can be seen from Table 1 above, in the case of the sintered layers of Examples 1 to 3 according to the present invention, as the temperature increases, the far-infrared radiation energy increases, and in particular, the radiation energy at 70° C. similar to the hot air temperature emitted from the hair dryer is It is about 15 times larger than the radiation energy measured at 37°C, and the radiation energy at 150°C, which is similar to the heating temperature of the bobbin, is so high that there is no significant difference compared to the radiation energy at 500°C.

That is, it was confirmed that the far-infrared radiation energy was maximized at 70 to 150°C, which corresponds to the use temperature range of the hair dryer, whereas in the case of the control group omitting the sintering process, when compared to Examples 1 to 3, at 70 to 150°C. It was confirmed that the far-infrared radiation energy was significantly reduced.

When viewed with the naked eye, the sintered layer of Comparative Example 1 was in a defective state that could not be used as a normal product because part of the surface was not attached to the surface of the bobbin assembly plate and was floating.

[Comparative Example 2]

A sintered layer was formed in the same manner as in Example 1, except that the sintering temperature in Example 1 was sintered at 850°C for 10 minutes.

Comparative Example 2 could not be used as a product because the bobbin assembly plate itself was weakened enough to break when pressed with a finger.

[Comparative Example 3]

In Example 1, a sintered layer was formed in the same manner as in Example 1, except that the first powder was omitted and the sintering composition was mixed with 150 parts by weight of the second powder and 110 parts by weight of water. And, unlike Example 1, the second powder was prepared by mixing kaolin, bentonite, and zeolite at a weight ratio of 1:0.6:0.3.

The results of measuring the far-infrared emissivity and radiation energy at different temperatures for the specimen of Comparative Example 3 are shown in Table 2 below.
