(57) [Summary] [Purpose] The purpose is to keep the power control element in a normal state without trapping heat inside the controller, and to make the controller smaller. [Structure] A heat dissipation plate 8 is attached to the power control element 6 disposed in the controller 3, and most of the heat dissipation plate 8 is extended to the back surface of the carpet body 2 to dissipate the heat generated from the power control element 6. The liquid is discharged to the outside of the controller 3 via the plate 8.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to an electric carpet that is laid on a floor or the like in a room to provide heating.

0002

[Conventional technology]

The structure of a conventional electric carpet is as shown in FIGS. 3 and 4. The carpet body 2 is made of synthetic fiber etc. and the edge of this carpet body. The controller 3 is attached to the heating element 1 and controls the temperature of the heating element 1. .

0003 The controller 3 is a hollow space formed by an upper case 4 and a lower case 5. In between, a power source consisting of a triac, etc. that supplies power to the heating element 1 and controls the phase. a control element 6; a control board 7 that includes the power control element 6 and constitutes a control circuit; A heat sink 8 is provided to release heat generated from the power control element 6. Ru. The control board 7 and the power control element 6 are electrically connected by a lead wire 9. The heat sink 8 is attached to the control board 7 at both ends with screws 10, 10. electricity system The control element 6 is fixed to the heat sink 8 with screws 11. 12 is a temperature control section, 13 is the power switch.

0004

[Problem that the idea aims to solve]

However, in the electric carpet configured as described above, the power generated by the power control element 6 is Since the heat dissipation plate 8 is disposed inside the controller 3, the heat is There was a risk that the power control element 6 would be damaged due to the power being trapped inside the controller 3. Further, a heat sink 8 is formed from the upper case 4 and lower case 5 of the controller 3. Since it is placed in a space, the disadvantage is that the controller 3 is thick and large. there were.

[0005] This invention was developed in consideration of these points, and it prevents heat from building up inside the controller. Our aim is to provide an electric carpet with a compact controller and a compact controller. The target is

[0006]

[Means to solve the problem]

In order to achieve this purpose, the present invention has developed a carpet book with a built-in heating element. and a controller attached to the edge of the carpet body to control the temperature of the heating element. controller, a power control element disposed within this controller, and a power control element disposed within this controller. and a heat sink attached to the carpet element, with most of the heat sink being attached to the carpet book. It extends to the back of the body.

[0007]

[Effect]

In this invention, most of the heat dissipation plate is extended to the back side of the carpet body, which makes it possible to The heat generated from the force control element is released outside the controller via the heat sink and is It does not get trapped inside the trawler. Additionally, the controller can be made smaller.

[0008]

【Example】

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

[0009] 2 is a carpet body made of synthetic fiber, etc., and this carpet body 2 generates heat. Body 1 is contained inside. 3 is the controller, which is attached to the edge of the carpet body 2 This is to control the temperature of the heating element 1. This controller 3 is made of synthetic resin An outer shell is formed by an upper case 4 and a lower case 5. Also, the lower case Reference numeral 5 denotes a storage section 5a which extends to the back side of the carpet body 2 and stores a heat dissipation plate which will be described later. , multiple release holes that release heat generated from the power control element (described later) via a heat sink. 5b...

0010 Inside the controller 3, there is a controller that supplies power to the heating element 1 and controls the phase. A power control element 6 consisting of a liac or the like, and a control circuit including this power control element 6 The heat generated from the control boards 7, 7 constituting the circuit and the power control element 6 is released. A part of the heat dissipation plate 8 is provided for cooling. This heat sink 8 is screwed at one end. 11 to the power control element 6, and most of the other end is stored in the storage section 5a. I am trying to pay it. Further, the control board 7 and the power control element 6 are connected by a lead wire 9. electrically connected. 10 is a lead wire connecting the control board 7 and the control board 7; , 12 is a temperature control section, and 13 is a power switch.

[0011] However, when using an electric carpet formed in this way, it is necessary to turn on the power switch. switch 13 is turned on, and the temperature adjustment unit 12 is operated to set the operating temperature. and, The control board 7 controls the operation of the power control element 6 based on the set temperature. The power control element 6 controls the supply of electricity to the heating element 1 in accordance with the control of the plate 7 . At this time, The heat generated from the force control element 6 is transmitted through the heat sink 8 to the storage section 5a of the lower case 5. It is discharged to the carpet main body 2 side from the plurality of discharge holes 5b formed.

0012 In this embodiment, most of the heat sink 8 connected to the power control element 6 is carpeted. Since it extends to the back of the body, the heat generated from the power control element 6 can be used as a controller. - 3 can be discharged outside the controller 3 without being trapped inside, preventing damage to the power control element 6. In addition to eliminating the fear of failure, the controller 3 can be made smaller.

[0013] Note that the electric carpet in this example refers to electric cushions and flooring used in the kitchen. It also includes ajita.

[0014]

[Effect of the idea]

According to the present invention, most of the heat sink that dissipates the heat generated from the power control element Since it is installed on the back side of the carpet, heat does not accumulate inside the controller and power is Not only can the control elements be maintained in a normal state, but the controller can also be made smaller. Ru.
