JP3055382U - Pillow with heat-sensitive heating wire. - Google Patents

Abstract

(57) [Summary] [Purpose] The purpose of the present invention is to provide a body pillow that can be used even in the cool season. [Structure] The body pillow of the present invention can obtain heat by attaching a surface-covered wiring having a heat-sensitive heating wire using electric power as a heat source.

Description

[Problems to be solved by the invention]

 Pillows, which are said to be used when sleeping or resting, can disperse body pressure and stabilize the psyche by hugging, and can be expected to shift to stable sleep. I have. However, there was a problem in the actual situation that similar use in the cool season caused heat to dissipate due to the gap between the comforter and the body and dissipated.

[0002]

[Means for Solving the Problems]

 The means of the present invention has a structure in which a pillow is stored in a cylindrical soft woven cloth in which heat-sensitive heating wires using electric power as a heat source are uniformly wired on the entire surface, so that the heating effect can be obtained during use in the cool and cool season. It can be used as a normal pillow in summer.

【Example】

 The above and the features and other advantages of the present invention will be described with reference to FIGS. Generally, copper and cadmium alloy are used as the material of the heat-sensitive heating element to be wired on the soft woven fabric. As shown in FIG. 1, a heat-generating wire 5 is wound around a heat-resistant fiber 1 such as a tetron core, covered with heat-resistant nylon 2 and hardened with heat-resistant vinyl 3.

A control method for maintaining the surface temperature of the heat-sensitive heating element at a comfortable temperature of about 60 ° C. will be described with reference to FIG. The heating wire 5 and the signal wire 4 wired on the soft woven fabric 6 are connected in parallel, and thus have an impedance (Z). A voltage division (Ez) is generated by this (Z) and the resistance (γ), and a constant phase delay is generated with respect to the power supply voltage (Ein). When (Ez) reaches the discharge voltage (Eo) of the discharge tube 11, it discharges, becomes a signal voltage, and this voltage becomes the gate input of the thyristor 10, controls the heating element (Ein) and repeats this. The desired temperature is arbitrarily set by the variable resistor 12. It is well known that the other selectable method is a bimetal temperature control method.

[Effect of the invention]

 As shown in FIG. 3, the embodiment of the present invention is used in a form in which a predetermined body pillow is stored in a soft-woven cloth tube in which a heat-generating body close to the shape and volume of the body pillow is wired. . In the past, in the cool season, it could not withstand use due to the dissipation of warm air due to the formation of gaps.However, a thermal effect was obtained by the heat-sensitive heating element, and it can be used throughout the year by turning off electricity in the summer. Was.

In addition, it is convenient to provide a fastener that can be separated and attached to the body of the pillow.

It should be understood that the present embodiment is an example, and that the shape of the body pillow itself can be variously changed by changing the shape.
