Abstract

(57) [Summary] [Purpose] To obtain a seat heater that can be installed even in narrow spaces. [Structure] In a seat heater in which a heater 5 having a reflective plate 4 arranged opposite to a heating element 1 is provided at the leg of the seat, the heating element 1 includes a heat dissipation plate 2 having a plurality of ventilation holes 2a;
An electric heater 3 integrated on one side of this heat radiation plate 2
It was formed by Therefore, the heat of the electric heater 3 is efficiently conducted to the heat radiation plate 2. In addition, since the heated air is convected through the ventilation hole 2a, heat is radiated more efficiently, so the heater 5 can be made smaller because the outer diameter of the electric heater 3 does not need to be increased or the overall length of the electric heater 3 need not be increased.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a seat heater having a heating element.

0002

[Conventional technology]

Conventionally, as shown in FIGS. 3 and 4, a reflecting plate is installed opposite to a heating element 7 consisting of a sheathed heater. A seat heater 9 to which a seat heater 8 is attached is provided on a leg portion 10a of a seat 10.

0003

[Problem that the idea aims to solve]

The installation space for conventional seat heaters varies depending on the shape of the seat, location, etc. The heater needs to be made smaller because it can be installed in a narrow space due to limited conditions.

0004 In addition, the heating element is a sheathed heater with a fixed power consumption, and its surface temperature is also Conventional sheathed heaters must be kept within the standard value of 400deg. When configuring a heating element as a single unit, if the outer diameter of the sheathed heater is increased, the sheathed heater The moldability of the sheathed heater deteriorates and cannot be solved simply by increasing the outer diameter of the sheathed heater. Therefore, it is recommended to increase the overall length of the sheathed heater and install it in a narrow space such as a two-person seat. There was a problem that made it difficult to fix.

[0005] The present invention aims to solve such problems.

[0006]

[Means to solve the problem]

In order to solve the above-mentioned problems, this invention has developed a heat dissipation plate with multiple ventilation holes. A seat heater consists of a heating element with an integrated electric heater on the surface and a reflective plate placed opposite it. This is what I did.

[0007]

[Effect]

Since the electric heater is integrated into the heat dissipation plate with ventilation holes, there is no electric heating when the electricity is turned on. The heat generated by the heater is efficiently conducted to the heat dissipation plate. Because of this heated heat dissipation Heat is radiated on the surface of the plate and the air heated by the heat dissipation plate passes through the ventilation holes. Heat is dissipated more efficiently due to convection. For this reason, the external shape and overall length of the electric heater The surface temperature can be easily lowered to below the standard value (400°C) without changing it.

[0008] Therefore, by attaching such a heating element, the seat heater can be made smaller, making it possible to seat two people. It can also be installed in narrow spaces such as seats.

[0009]

【Example】

An embodiment of the present invention will be described with reference to FIGS. 1 and 2.

0010 In the figure, 1 is a heating element, and this heating element 1 has a plurality of ventilation holes 2a. Plate 2 and one side of this heat dissipation plate 2 are wrapped or tightened to maintain heat conduction relationship. Electric heaters consisting of sheathed heaters integrated by methods such as brazing (not shown) It consists of 3 data. 4 is a reflecting plate, and this reflecting plate 4 is placed opposite to the heating element 1 to generate heat. The heat of the body 1 is reflected in the heating direction. 5 is a heater, which has a heating element 1 and a fitting for heating element 1. A reflector plate 4 is attached via a reflector plate 6.

[0011] The effects of the above configuration will be explained below.

0012 Since the electric heater 3 is integrated into the heat dissipation plate 2 having ventilation holes 2a, when the electricity is turned on, The heat generated by the electric heater 3 is efficiently conducted to the heat radiation plate 2. For this reason, Canada Heat is radiated on the surface of the heated heat dissipation plate 2, and the heated air flows through the ventilation holes 2. Since convection occurs through a, heat is dissipated more efficiently. Figure 2 shows heating element 1 like this. When installed in the container 5, the flow of convection is shown by an arrow. Therefore, the outer diameter of the electric heater 3 should be increased. Lowers the surface temperature to below the heater 5 standard value (400℃) without increasing the overall length or increasing the overall length. It's easy to do.

[0013] Therefore, by attaching such a heating element 1, the heater 5 can be made smaller.

[0014]

[Effect of the idea]

As described above, according to the present invention, an electric heater is integrated into a heat dissipation plate with ventilation holes. Since the heating element is configured with It has the advantage of being able to be installed in narrow spaces such as seats.
