Abstract

PROBLEM TO BE SOLVED: To prevent a skald burn by preventing steam from being generated by simultaneously dripping water onto a heater even when this water flows out because of the temperature rise of water tank due to the heater. SOLUTION: Concerning this hair curler, the heater and a water tank 4 as a water supply pant are provided so as to be connected/disconnected on a winding body 1 around which hair is wound, and a steam generating means is provided for discharging steam, which is generated when a water absorbing member 40 of water tank 4 touches the heater, through steam holes 13 formed on the surface of winding body 1 to the outside. Concerning such a hair curler, a water absorber/retainer 70 is arranged in the form of loop between the water tank 4 and the heater. Thus, even when the temperature of water tank 4 rises because of heat conduction or heat radiation from the heater and water flows out of the water tank 4 in the state of disconnecting the water tank 4 and the heater, this flowing-out water is absorbed and temporarily retained by the water absorber/retainer 70 so that the flowing-out water does not simultaneously touch the heater, a lot of steam is not unexpectedly generated at once and there is no danger of skald burn.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair curling device for generating steam to give hair to a hair.

[0002]

2. Description of the Related Art A conventional hair curling device of this type has a heater inside a winding drum around which hair is wound and a water tank as a water supply section, and the water tank is slidable in the longitudinal direction of the winding drum. Thus, the water tank and the heater can be freely separated from each other, and a spring such as a coil spring disposed between the water tank and the heater is urged to separate the water tank and the heater. In this hair curling device, the heater and the water tank are normally kept out of contact with each other by urging with a spring, but if the water tank is pushed in against the spring,
The heater and the water-absorbing member of the water tank come into contact with each other, and discharge steam to the outside through a steam hole formed in the surface of the winding drum.

[0003]

However, in the above-mentioned conventional example, since the water tank is adjacent to the heater, the heat generated by the heater is transmitted through a spring and a cylindrical body for guiding the sliding of the water tank. The temperature of the water tank rises due to the radiant heat of the heat that is transmitted to the water tank or generated by the heater, the internal pressure of the water tank increases, and the part of the water tank that contacts the heater is kept in non-contact with the heater. Spills out of the water tank. When a large amount of water flowing out of the water tank is dropped on the heater at one time, steam is generated at a time, and when the user brings the hair curl device close to the skin, there is a risk of burns due to the steam. In addition, unexpected steam generation when the water tank is not pressed is highly likely to cause burns.

SUMMARY OF THE INVENTION The present invention has been made in view of the above description, and prevents water from dropping at once to a heater to generate steam even if water flows out due to a rise in the temperature of a water tank by the heater. The task is to avoid burns.

[0005]

In order to solve the above-mentioned problems, a hair curling device according to the present invention is provided with a heater and a water tank as a water supply unit provided on a winding drum around which hair is wound so as to be freely separated from the water tank. A steam generating means for discharging steam generated when the water absorbing member comes into contact with the heater to the outside through a steam hole formed in the surface of the winding drum, wherein a water absorbing and retaining body is annularly provided between the water tank and the heater. It is characterized by being arranged. Even if the temperature of the water tank rises due to heat transfer or heat radiation from the heater when the water tank and the heater are separated from each other and water flows out of the water tank, the water that has flowed out is absorbed by the water absorbing and retaining body. Water is temporarily held, and the outflowing water does not come into contact with the heater at once, and a large amount of steam is not suddenly generated at once, and there is no risk of burns.

[0006] It is also preferable that the annular water-absorbing and retaining body is arranged so as to close a space between the heater and a cylindrical body for guiding sliding of a water tank as a water supply unit. In this case, even if the water flows out of the water tank, the water is reliably absorbed by the water absorbing and retaining body without being accumulated between the tank and the heater, and the unexpected generation of steam can be more reliably prevented.

It is also preferable that a cutout is provided at a position facing the steam hole of the water-absorbing and retaining body. In this case, even when the annular water-absorbing / water-retaining body is provided, it is possible to prevent the water-absorbing water-retaining body from interfering when steam generated when using steam is released from the steam hole.
It is also preferable that a notch is provided at a position corresponding to the steam hole on the side of the cylinder that guides the sliding of the water tank. Also in this case, even when the water-absorbing and retaining body is present, it is possible to prevent the water-absorbing and retaining body from interfering when the steam is discharged from the steam hole.

[0008] It is also preferable that a spring interposed between the water tank and the heater is provided with a water-absorbing / water-holding portion in order to bias the water tank and the heater apart. In this case, even if the temperature of the water tank rises due to heat transfer or heat radiation from the heater in a state where the water tank and the heater are separated from each other and the water flows out of the water tank, the outflow water is provided in the spring. The water absorbed and retained by the water absorbing and retaining section temporarily retains water, so that the outflowing water does not come into contact with the heater at once and suddenly generates a large amount of steam at once, and there is no risk of burns. In addition, since the water absorbing and retaining portion is provided on the spring, the number of components can be reduced as compared with the case where a water absorbing and retaining body is separately provided.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An example of an embodiment of the present invention will be described. This hair curling device is of a steam type, and as shown in FIGS. It comprises a rod-shaped winding drum 1 protruding from the front end, and a clip 2 pivotally attached at the front end side of the grip portion 3 and coming into contact with the outer surface of the winding drum 1 by spring bias. A heater block 5 for heating the body 1 and generating steam by heating water supplied from a water tank 4 mounted on the tip of the winding cylinder 1 is housed. The power cord 30 for supplying power to the power supply 5 is derived. In the figure, reference numeral 31 denotes a switch for controlling the energization of the heater block 5, and 32 denotes a light-emitting display unit for displaying that the power is being supplied.

[0010] The heater block 5 disposed in the winding drum 1
Is a PTC heater 50 as shown in FIG. 1, FIG. 2 and FIG.
Are formed in such a manner that alumina plates 51, 51 and semicircular heat sinks 52, 52 are disposed on both surfaces thereof in a bottomed cylindrical heater pipe 53, respectively. A plurality of ridges 54 running in the direction are provided at intervals in the circumferential direction, and a convex portion 55 is provided at the center of the closed end face of the heater pipe 53. When the heater block 5 is housed in the cylindrical winding drum 1, the outer surface of the ridge 54 contacts the inner peripheral surface of the winding drum 1.

The winding drum 1 is formed of a synthetic resin or metal made of a good conductor, and a plurality of dovetail grooves 10 running in the axial direction are formed on an outer surface except for a portion facing the clip 2 in a circumferential direction. Are provided at intervals. Also clip 2
On the inner peripheral surface of the portion facing to the heater pipe 53, there is provided a recess forming a space serving as a steam reservoir 14 between the outer peripheral surface of the heater pipe 53 and a plurality of steam holes 13 for steam ejection. The steam reservoir 14 is connected to the outer surface, which is a surface, by a steam hole 13. Such a winding drum 1 can be formed simultaneously with the dovetail groove 10 and the above-mentioned recess by extrusion molding.

A cylindrical body 11 is attached to the end of the winding drum 1. The water tank 4 is slidably held by the cylindrical body 11 and is detachable from the cylindrical body 11. A water-absorbing member 40, such as a felt, that comes into contact with the water contained in the water tank 4 in the water tank 4 is disposed on a front end surface of a portion of the water tank 4 that is inserted into the winding drum 1. The distal end surface of the water absorbing member 40 is always kept in a non-contact state with the heater block 5 by being biased by a spring 59 such as a coil spring disposed between the distal end surface of the water absorbing member 40 and the distal end surface of the heater block 5. When the tank 4 is pushed in against the spring 59, the water absorbing member 40 comes into contact with the tip surface of the convex portion 55 of the heater block 5 as shown in FIG. Therefore, when the heater block 5 is energized and the heater block 5 is heated, if the water tank 4 filled with water is pushed in to bring the water absorbing member 40 into contact with the convex portion 55, the water absorbing member 40 is held. Steam is generated by the heating and evaporation of the water, and the steam is discharged from the steam hole 13 to the outer surface of the winding drum 1 through the steam reservoir 14.

In the case of the present invention, as shown in FIG. 1, FIG. 2 and FIG. 8, a water-retaining felt-like material is provided between the opposed surface of the cylindrical body 11 for slidably holding the water tank 4 and the heater block 5. A water absorption / water retaining body 70 is interposed. The water-absorbing and retaining body 70 is formed in a substantially annular shape, and includes the cylindrical body 11 and the heater block 5.
Are closed so as to extend substantially in the circumferential direction. By the way, as shown in FIG. 1, in a state where the water absorbing member 40 of the water tank 4 and the convex portion 55 of the heater block 5 are separated, the heat generated in the heater block 5 is transferred to the water tank 4 via the spring 59 and the cylindrical body 11. The temperature of the water tank 4 rises due to the heat transfer or the radiant heat of the heat generated by the heater block 5, the internal pressure in the water tank 4 increases, and the water in the water tank 4 may flow out. The water is absorbed by the water absorbing and retaining body 70 to retain the water, and is evaporated by the heat of the heater block 5. Therefore, the water overflowing from the water tank 4 evaporates gradually without being evaporated at once. For this reason, unlike a conventional case, a large amount of steam is not suddenly generated, and there is no risk of burns. Further, as described above, the water absorbing and retaining body 70
Are arranged so as to close substantially in the circumferential direction, so that the opposing surfaces between the cylindrical body 11 and the heater block 5 are connected, and the water flowing out of the water tank 4
The water absorbing and retaining body 70 absorbs and retains water without accumulating on the contact surface between the water absorbing and retaining body 70 and the water absorbing and retaining body 70, so that the water overflowing from the water tank 4 can be reliably prevented from evaporating at once. As shown in FIG. 8, a notch 71 is provided in a part of the annular water absorbing and retaining body 70 in the circumferential direction, and the notch 71 is located at a position corresponding to the steam hole 13 of the winding drum 1. When the notch 71 is provided and the portion of the notch 71 corresponds to the portion of the steam hole 13, the steam generated by bringing the water absorbing member 40 into contact with the heater block 5 is discharged from the steam hole 13. Sometimes there is no obstacle.

Further, a plurality of cutouts 71 provided in the annular water absorbing and retaining body 70 may be provided as shown in FIG. FIG.
The cutout 71 may be provided by reducing the thickness perpendicular to the circumferential direction without completely cutting the water absorbing and retaining body 70 as shown in FIG. Further, as shown in FIG. 11, a notch 71 may be provided by reducing the thickness at a portion corresponding to the steam hole 13 of the annular water-absorbing and retaining body 70. In this case, the side where the notch 71 is provided may be the heater block 5 side or the cylinder 11 side. Further, as shown in FIG. 12, the water-absorbing and retaining body 70 may be formed in an annular shape in the circumferential direction, and the cylindrical body 11 may be provided with a notch 71 at a position corresponding to the steam hole 13. 1 and 2 show examples in which the structure of FIG. 12 is adopted. Notch 71
May be provided on both the tubular body 11 and the water-absorbing and retaining body 70.

Further, as shown in FIGS. 13 and 14, a spring 59 such as a coil spring is subjected to flocking processing, and this flocking processing portion is used as a water absorbing / water retaining section 72. In this case, the water that has flowed out of the water tank 4 is absorbed and retained by the flocculated water absorbing and retaining portion 72 of the spring 59, and this water is supplied to the heater block 5 via the spring 59,
It is evaporated by the heat of the heater block 5. When the water absorption / water retaining portion 72 is provided by performing the flocking process on the spring 59 in this manner, a large amount of water in the water tank 4 drops to the heater block 5 without obstructing the generation of steam unlike the water absorption / water retaining body 70 described above. However, generation of a large amount of steam can be prevented. Further, the water that has oozed out of the water tank 4 is gradually guided to the heater block 5 side by the water absorbing and retaining section 72 of the spring 59 and is evaporated, so that a large amount of water is dripped onto the heater block 5 at a time and a large amount of steam is generated. Can prevent it from occurring.

A plurality of guards 6 are provided in the region of the winding drum 1 not facing the clip 2 at intervals in the axial direction of the winding drum 1.
Is arranged. Here, the guards 6 are connected by a plurality of connecting pieces 60 running in the axial direction of the winding drum 1. Each connecting piece 60 is inserted into the dovetail groove 10 formed on the outer surface of the winding drum 1. By being arranged, it is embedded in the winding drum 1, and the outer surface of the connecting piece 60 is flush with the surface of the winding drum 1 or at a position recessed from the surface of the winding drum 1. Here, in order to make the guard 6 detachable from the winding drum 1, the width of each connecting piece 60 is set to be almost the same as or smaller than the opening width of the dovetail groove 10 so that the elasticity of the guard 6 is improved. The connecting piece 60 is pulled out from the dovetail groove 10 by spreading the guard 6 by using the same.
The guard 6 can be detached from the winding drum 1, and the elasticity of the guard 6 prevents the connecting piece 60 from coming out of the dovetail groove 10 when the guard 6 is attached to the winding drum 1. FIG. The guard 6 may not be attached or detached by setting the cross-sectional shape of the connecting piece 60 to the cross-sectional shape of the dovetail groove 10 as shown in FIG.
In the case shown in FIG. 15, the guard 6 is attached to the winding drum 1 by connecting the connecting piece 60 to the winding drum 1 in a state where the tubular body 11 is not mounted from the end face opening of the dovetail groove 10. This is done by plugging. The connecting piece 60 is free in the axial direction and restricts the movement of the guard 6 by friction with the dovetail groove 10. At this time, the movement of the guard 6 may be restricted by friction on the entire surface of the connecting piece 60. Also, as shown in FIG.
The friction protrusion 61 may be provided on a part of the zero, and the movement may be restricted by the frictional contact of the friction protrusion 61. If you do this,
Shrinkage and expansion due to heat move the portion where the friction protrusion 61 is not provided, so that no deformation or bending of the member occurs. The movement of the entire guard 6 by an external force can be suppressed by the frictional contact of the friction protrusion 61 provided in a part.

The temperature of the clip 2, the grip portion 3, and the cylinder 11 which come into contact with the winding drum 1 becomes high due to the heat transfer from the winding drum 1, but the clip 2, which reduces the perceived temperature when touching this portion, 4 and 5 for the grip portion 3 and the cylindrical body 11,
As shown in FIG. 6, ribs 91, 92 and 93 are provided.
As a result, the possibility of a burn even if the body is inadvertently touched is reduced.
