Abstract

PURPOSE:To enable a steambrush to prevent the occurrence of dew condensation without the need for a separate heat source by installing a steam guide made of a heat conducting material opposite a heater between a steam generating unit and a brush base. CONSTITUTION:Heat generated by a heater 11 heats up the surface of a heater case 13 and is then conducted to water absorption elements 12 and 23 heating up water contained therein, resulting in the generation of steam. A brush section 3 is provided with a steam guide 26, from which the steam guided from openings 24 and 25 of a heater holder 15 into the central part of a brush base 4 is discharged. With the steam guide 26, a spacer 27 made of a material of excellent heat conductivity such as copper, etc., and formed in a square block has vents 30 protruded for upward discharge of the steam at four corners of its top side surface to be connected through vertical paths with two steam delivery slots 31 formed on each side. Dew condensation does not occur because the spacer 27 is kept at high temperature as it is heated up by heat from a heater case 13 heated up by heat generated by the heater 11. The utilization of the heater 11 of a steam generation unit 9 as the heat source tables the structure to be simplified.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steam hair brush for discharging steam generated by a steam generator from a brush base.

[0002]

2. Description of the Related Art A steam hair brush of this type is used for softening and redressing hair, or for brushing while caring for hair. As this steam hair brush, for example, a hollow brush base is provided at the tip of the handle, a steam generator is provided inside the handle, and steam generated by the steam generator is guided to the brush base. There is a steam discharge hole provided at a location (for example, see Japanese Utility Model Publication No. 53-17956). There is also a steam generator provided inside the brush base so that steam is discharged from a steam discharge hole formed between bristles of the brush base (for example, Japanese Utility Model Publication No. 55-121301). See Japanese Patent Publication No. 62-40004).

[0003]

However, in the former conventional example in which steam generated by the steam generator in the handle is guided to the brush base and discharged, the handle and brush base that generate steam are generated. Since it has a positional relationship with the steam discharge hole of, the middle of the path from the handle to the steam discharge hole is cold when not in use, and steam is likely to condense on the surface along the path to form water droplets. . Also in the latter conventional example, steam causes dew condensation on the cold inner surface of the brush base portion having the steam discharge holes. The water droplets resulting from such condensation may be clogged in the steam discharge hole or may be dropped from the steam discharge hole to wet the hair more than necessary.

Therefore, an object of the present invention is to prevent clogging of the steam discharge holes and prevent water droplets from falling on the hair by taking measures against dew condensation in such a steam hair brush.

[0005]

According to the present invention, a brush base 4 having a bristle 7 is planted on the outer surface of a brush base 3 having a steam generator 9 having a heater 11 as shown in the drawing. In the installed steam hair brush, the steam generated by the steam generating device 9 is interposed between the steam generating device 9 and the brush base 4.
A steam guide body 26 having a steam discharge hole 31 which is guided and discharged between the roots of the bristles 7 is arranged. A part or the whole of the steam guide body 26 is made of a heat conductive material and is brought into contact with the heater 11.

[0006]

In use, the steam guide body 26 is kept at a high temperature by the heat of the heater 11 and therefore does not cause dew condensation.

In FIG. 5, a brush base 4 made of silicon rubber or the like is stretched on the upper half of the outer peripheral surface of the brush base 3. The brush base 4 is fixed by pressing the outer peripheral edge of the brush base 4 onto the brush base 3 with a brush pressing member 5. The brush pressing member 5 has an engaging claw 6, which is engaged with the brush base portion 3 in a retaining manner. A large number of bristles 7 are planted on the brush base 4 in the front, rear, left and right at a predetermined pitch. Since the brush base 4 itself imparts appropriate elasticity in the vertical direction, brushing can be performed smoothly while caring for the hair.

On the other hand, a steam generator 9 is incorporated inside the brush base 3. As shown in FIGS. 1 and 5, the steam generator 9 includes a water supply tank 10 that is detachably attached to the tip of the brush base 3, a heater 11 such as a positive temperature coefficient thermistor, and a heater for supplying water in the water supply tank 10. The water absorbing body 12 is supplied to the 11 side. The heater 11 is formed by enclosing a heater element 16 in a heater case 13. The heater 11 is waterproofed and sealed inside a cylindrical heater holder 15 which is mounted inside the brush base 3 with screws 14. As shown in FIG. 4, the lead wire 17 led out rearward from the heater element 16 of the heater 11 includes a power cord 19 attached to the rear end of the handle 2, a circuit board 20, and a switch 1.

The exposed part of the second water absorbing body holder 22 is the heater case 13
Is abutted directly on the front end portion of or through another water absorbing body 23 that covers the heater case 13. Therefore, due to the heat generated by the heater 11, the surface of the heater case 13 is heated and transmitted to the water absorbent bodies 12 and 23, and the water contained in the water absorbent bodies 12 and 23 is heated to generate steam.

The water absorbent body holder 22 has the packing body 38.
Is fitted externally, and the packing body 38 comes into close contact with the inner peripheral wall of the heater holder 15 by mounting the water supply tank 10 so that the steam generated from the location does not escape to the outside. That is, in the heater holder 15, a steam chamber is formed between the packing body 38 on the water supply tank 10 side and the heater waterproof sealed portion on the heater 11 side,
The steam emanating from the water absorbing bodies 12 and 23 can be discharged from the inside of the heater holder 15 only toward the substantially central region of the brush base 4. Therefore, FIG. 5 and FIG.
2, an opening 24 is provided in a portion of the brush base 3 facing the central region of the brush base 4, and an opening 25 is provided in a portion of the peripheral surface of the heater holder 15 facing the opening 24. To steam brush base 4
The steam guide body 26 that guides and spits out almost the central area of the
Put on. In this embodiment, the steam guide body 26 comprises a spacer 27 and an outlet piece 29.

The spacer 27 is made of aluminum die cast, copper,
The material is formed into a square block with a material having excellent thermal conductivity such as brass, and the discharge port 30 is formed from the four corners of the upper surface as shown in FIG.
Of the steam discharge hole 31 in each discharge port 30
Two are provided in a vertically penetrating manner. As shown in FIGS. 1 and 5, the spacer 27 is arranged in the openings 24 and 25 so that the lower surface of the spacer 27 comes into contact with the outer surface of the heater case 13 directly or through the water absorbing body 23. On the lower surface of the spacer 27, which is in contact with the heater case 13, there are steam passages 32 communicating with the lower ends of all the steam discharge holes 31.
Is recessed.

The upper surface of the spacer 27 is covered with an outlet piece 29 made of a heat-resistant plastic made of PPS resin (polyphenylene sulfide) or the like which is excellent in heat resistance and rigidity. As shown in FIG. 6, the outlet piece 29 is formed in an uneven shape corresponding to the uneven shape of the upper surface of the spacer 27 and has an upward convex portion 35 that covers the ejection port 30. The convex end wall of the convex portion 35 has an upward convex portion 35. A steam discharge hole 36 communicating with the steam discharge hole 31 is provided. As shown in FIGS. 1 and 5, a felt 33 is interposed between the discharge port 30 and the inner surface of the protruding end wall of the convex portion 35 to prevent water droplets from falling and dust from entering the steam discharge hole 36.

The outlet piece 29 has a flange 28 at the lower portion of its peripheral surface. As shown in FIGS. 1 and 5, the flange 28 is formed on the inner surface of the peripheral edge of the opening 24 of the brush base 3 and the peripheral edge of the opening 25 of the heater holder 15. The outlet piece 2 is placed in the opening 24 by fitting the outlet piece 2 into the opening 24.

The four projections 35 on the upper surface of the outlet piece 29 are, as shown in FIGS. 1 and 5, four holes 37 (see FIG. 6) provided between the bristles 7 in the central region of the brush base 4. ) Is fitted so that the protruding end wall of each convex portion 35 is exposed so as to be substantially flush with the outer surface of the brush base 4.
As described above, the outlet piece 29 has the convex portion 35.
Is fitted in the hole 37 of the brush base 4, and the inner surface of the central portion of the brush base 4 is supported on the inner bottom of the recess 39 formed between the protrusions 35, 35, so that the brush base 4 becomes excessive. It is not dented or misaligned.

In this case, since the spacer 27 is kept at a high temperature by the heat of the heater case 13 heated by the heat generated by the heater 11 during use, dew condensation is not generated. Since the heater 11 of the steam generator 9 is used as the heat source for preventing dew condensation, a heat source different from the heater 11 is unnecessary, and the structure becomes simpler.

In the above-mentioned embodiment, the steam guide body 26 is formed by covering the upper surface of the spacer 27 with the outlet piece 29, but the outlet piece 29 is not always necessary. That is, as shown in FIG. 7, the entire steam guide body 26 may be made of a material having good heat conductivity, and the felt 33 may be arranged at the upper end of the opening of the steam discharge port 31.

As shown in FIG. 8, in the steam guide body 26, an upper surface of a spacer 27 made of a heat conductive material is covered with an outlet piece 29 made of heat-resistant plastic, and a recess 40 is provided on the lower surface side of the spacer 27. This recess 4
The heat-resistant plastic piece 41 may be fitted in 0.

Further, as shown in FIG. 9, a recess 40 may be provided on the lower surface side of the spacer 27 made of a heat conductive material, and a heat resistant plastic piece 41 may be fitted into the recess 40 via a felt 33.

As shown in FIG. 10, the steam guide body 2
A part of the upper surface having the steam discharge holes 31 of 6 can be installed so as to project further outward than the outer surface of the brush base 4. According to this, steam can be penetrated to the root of the hair as much as possible during brushing. Although a soft material such as silicon rubber is used as the material of the brush base 4 in the above embodiment, it may be made of a hard synthetic resin integrally forming the bristles 7 instead.

[0020]

As described above, according to the present invention, the steam guide body 26 made of a heat conductive material is disposed between the steam generator 9 and the brush base 4 so as to contact the heater 11. Therefore, since the steam guide body 26 is kept at a high temperature by the heat of the heater 11, dew condensation does not occur, and it is possible to prevent clogging of the steam discharge port 31 due to dew condensation water droplets and drop of water droplets on hair. . Moreover, since the heater 11 of the steam generator 9 is used, no special heat source is required.
