Description

The present invention relates to a heat insulating vest.

Conventionally, as clothing for cold weather, a heat-retaining vest that has a bendable planar or linear heater in which a heating wire such as a nichrome wire is coated with a heat-resistant wire such as a glass cloth to keep a wide range of the human body warm is known. (See, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 9-11515

However, the heater using the nichrome wire has a problem that it takes time to warm up to a temperature suitable for heat retention, and the life of the heater is short because the nichrome wire is disconnected by repeatedly energizing.

Therefore, a technical problem to be solved in order to provide a heat-retaining vest that warms up quickly and is suitable for repeated use arises, and an object of the present invention is to solve this problem.

In order to achieve the above object, the heat insulating vest according to the present invention is a heat insulating vest to which a heating element is attached, and the heating element includes a heat generating sheet containing carbon graphene.

According to this configuration, the heat-generating sheet containing carbon graphene can quickly and efficiently heat the heat by rapidly emitting far-infrared rays having excellent profound force on the human body. In addition, the heat-generating sheet is less likely to be damaged like a conventional heater, and a heat-retaining vest with excellent durability can be obtained.

Further, the heat insulating vest according to the present invention preferably includes a conductive sheet in which the heating element is in contact with one surface of the heating sheet, and electrodes provided at both ends of the conductive sheet.

In the present invention, it is possible to obtain a heat-retaining vest that can be heated quickly and efficiently and has excellent durability.

The front view and the back view of the heat insulation vest which concerns on one Embodiment of this invention. (A) is a perspective view showing a heating element, and (b) is a partially omitted cross-sectional view taken along the line AA in (a).

An embodiment of the present invention will be described with reference to the drawings. In the following, when referring to the number, numerical value, quantity, range, etc. of components, it is limited to the specific number unless it is clearly stated or in principle it is clearly limited to the specific number. It is not a thing, and it may be more than or less than a specific number.

In addition, when referring to the shape and positional relationship of components, etc., unless otherwise specified or when it is considered that this is not the case in principle, those that are substantially similar to or similar to the shape, etc. shall be used. include.

In addition, the drawings may be exaggerated by enlarging the characteristic parts in order to make the features easy to understand, and the dimensional ratios and the like of the components are not always the same as the actual ones.

FIG. 1A is a front view showing the heat retaining vest 1, and FIG. 1B is a rear view showing the heat retaining vest 1. The heat-retaining vest 1 has a front opening, and the clothing material is composed of an outer material and a lining, but the shape of the heat-retaining vest 1 is not limited to this. The outer material of the heat retention vest 1 is water repellent. The heat retaining vest 1 includes a heating element 2, a battery 3, and a controller 4.

FIG. 2 is a perspective view showing the heating element 2. The heating element 2 is formed in a planar shape, and is attached to the back body 11 of the heat insulating vest 1 by being sandwiched between the outer material and the lining. The heating element 2 exhibits a cell structure (carbon graphene cell) including a heating sheet 21, a conductive sheet 22, and an electrode 23. Further, the front surface and the back surface of the heating element 2 may be laminated with a protective film or the like.

In the heat generating sheet 21, a heat generating layer containing carbon graphene as a conductive material is formed on the base material. The carbon graphene cell is obtained by, for example, a chemical vapor deposition method (CVD method) or the like. The two heat generating sheets 21 are stacked so that the heat generating layers face each other.

The conductive sheet 22 is laminated over the entire surface of the heat generating sheet 21 so as to be in contact with the heat generating layer. The conductive sheet 22 is made of, for example, silver. The conductive sheet 22 may be silver powder or the like adhered to the entire surface of the heat generating sheet 21.

The electrodes 23 are copper electrodes stretched in the vertical direction, and are provided at both left and right ends of the heat generating sheet 21 via the conductive sheet 22.

The battery 3 is housed in the pocket 5 and is connected to the electrode 23 via a cable (not shown) wired between the outer material and the lining of the heat insulating vest 1. The battery 3 is a mobile battery or the like that can be disconnected from the cable and can be recharged repeatedly.

The controller 4 controls the operation of the heating element 2. Specifically, the controller 4 switches the energization of the electrode 23 on / off or increases or decreases the power consumption of the electrode 23 based on the input operation of the user (wearer) via the switch 6 provided on the left front body. Let me. The switch 6 is preferably configured to be turned on / off according to the energization status of the electrode 23.

Next, how to use the heat retention vest 1 will be described.

[Start heating]
First, when the controller 4 detects a long press input of the switch 6 by the user for a predetermined time (for example, 3 seconds) or longer while the heating element 2 is stopped, the battery 3 starts energizing the electrode 23. Then, the entire surface of the heat generating sheet 21 is energized via the conductive sheet 22, and the entire heat generating sheet 21 starts heating. Further, since the conductive sheet 22 is provided over substantially the entire surface of the heat generating sheet 21, the heat generating sheet 21 can be efficiently energized.

Immediately after energization, the heat generating sheet 21 emits far infrared rays (life light waves, growing wavelengths) of about 4 to 14 μm, which are excellent in profound force to the human body. As a result, the user can be warmed up quickly and efficiently. Further, the heat generating sheet 21 is suitable for repeated use because the nichrome wire is not broken unlike the conventional heater.

[Temperature adjustment]
Next, when the controller 4 detects that the switch 6 is pressed in the thermal state of the heating element 2, the controller 4 switches to the power consumption for each different temperature range set in advance. As a result, the temperature of the heating element 2 can be switched stepwise (for example, three steps corresponding to high temperature, medium temperature, and low temperature). The temperature at each stage can be set arbitrarily.

[Heat stop]
Further, in the heating state of the heating element 2, when the controller 4 detects a long press input of the switch 6 by the user for a predetermined time (for example, 3 seconds) or longer, the energization of the electrode 23 is stopped and the heating element 2 heats up. Stop.

It should be noted that the present invention can be modified in various ways as long as it does not deviate from the spirit of the present invention, and it is natural that the present invention extends to modified ones.
