Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an electric heating device equipped with a cord holder for holding an electrical connection cord led out from a planar heating device body having a heating element.

[Conventional technology]

Recently, there is an electric heating device in which a heating element is disposed inside a heating device body formed into a planar shape.

Examples of this type of electric heating equipment include electric carpets and electric bed pads.

Conventionally, as shown in FIG. 4, in an electric heating device, a cord heater (not shown), for example, is disposed inside the heating device main body 1 as a heating element. A controller box 2 is provided on one side of the heating device body 1. An electrical connection cord 3 is connected to the controller box 2. The electrical connection cord 3 is connected to an indoor outlet 4.

In addition to the cord heater, a temperature detection line (not shown) is provided inside the heating device main body 1 and is connected to the controller box 2. That is, when the electrical connection cord 3 is connected to the outlet 4,
By turning on the power switch of the controller box 2, the cord heater generates heat, and at the same time, the temperature of the heating device body 1 is detected by the temperature detection wire.

Furthermore, inside the controller box 2,
The cord heater is energized and controlled in response to a signal from the temperature detection line.

[Problem that the invention attempts to solve]

However, since the electrical connection cord 3 is made long in order to be connected to an indoor outlet 4, it may get in the way. That is, if the controller box 2 and the indoor console 4 are located close to each other, the electrical connection cord 3 may become too much of a hindrance.

For this reason, the excess portion of the electrical connection cord 3 is pushed into the underside of the heating device main body 1 or left on the floor indoors.

Furthermore, if the controller box 2 and the indoor outlet 4 are far apart, the long electrical connection cord 3 will be left on the floor of the room and used.

In such a state, there is a problem in that the electrical connection cord 3 can cause the user's foot to get caught or become entangled with the body, which is extremely troublesome for the user.

Further, there is a problem in that if the left electrical connection cord 3 is stepped on with a foot or pressed with a foreign object, the electrical connection cord 3 will be damaged.

Therefore, the purpose of the present invention is to hold the cord derived from the electric heating device body in a cord holder,
To provide an electric heating device that prevents user discomfort and accidents.

[Means for solving problems]

According to the present invention, the heating device has a main body that includes a heating element and is formed into a planar shape, and has a groove for removably receiving and holding one side of the heating device main body, and a groove on the opposite side of the groove for receiving and holding the heating device body in a detachable manner. A cord holder is integrally formed with a groove for removably storing a cord led out from the tool body, and both opening ends of the groove for storing the cord are formed in directions facing each other. The electric heating device is characterized in that the opening of the groove is closed, a cord pull-out portion is formed on the closed side of the groove, and the cord holder and the cord are held in the heating device main body.

〔Example〕

1 to 3 show an embodiment of the electric heating device of the present invention.

The illustrated electric heating device includes a heating element (not shown) and has a heating device main body 10 formed in a planar shape. As the heating element, for example, a cord heater coated with an electrically insulating coating or a planar heater in which a metal resistance band is disposed between two films is used. Such a heating element is arranged inside the heating device main body 10. The heating device main body 10 is made of a flexible material, a wooden board, or the like.

A flexible cord holder 11 is held on one side of the heating device main body 10. The cord holder 11 is made of a flexible resin or rubber material. The cord holder 11 has a warming device main body 1
A first groove 13 is formed so as to sandwich the upper and lower surfaces of one side of 0. A protrusion 15 is formed on the inner surface of this first groove 13 . First groove 13
A second groove 18 is formed on the opposite side to receive and hold the electrical connection cord 16.

The first groove 13 and the second groove 18 are integrally formed at the bottom 20 in common. The openings at both ends of the second groove 18 are formed so that the openings are closed by the ends 22 of each other.

A cord pull-out portion 25 is formed in a portion of each end portion 22 of the second groove 18 . This cord pull-out portion 25 is formed at a longitudinally intermediate portion of the cord holder 11 .

Now, the cord holder 11 is fitted into one side of the heating device main body 10 by pushing the pair of side walls of the first groove 13 apart in opposite directions. After that, since the pair of side walls of the first groove 13 are restored, the heating device main body 10
A cord holder 11 is held on one side.

Furthermore, the electrical connection cord 16 is accommodated and held in the second groove 18 of the cord holder 11 . When the pair of side walls of the second groove 18 are pushed apart in opposite directions, a gap is created between the respective ends 22 of the second groove 18, and the electrical connection cord 16 is inserted through the gap. 16 is the second groove 18
is stored inside.

Further, the electrical connection cord 16 housed in the second groove 18 can be pulled out from a cord pull-out portion 25 formed in the middle portion of the cord holder 11.

By the way, the cord holder 11 has a second groove 1.
A partition portion 35 is formed that protrudes from one side of the interior of 8.

In the partition part 35, the electrical connection cord 16 is folded back and held inside the second groove 18 using the partition part 35 as a partition. That is, the electrical connection cord 16
Because the electrical connection cord 16 is folded back and stored and held inside the second groove 18 due to the length of the second groove 18, the excess electrical connection cord 16 is reliably stored and held.

In this way, the electrical connection cord 16 led out from the controller box 30 provided on one side of the heating device main body 10 is housed and held in the cord holder 11 and connected to the outlet 31 in the room.

[Effect of idea]

As explained above, according to the electric heating device of the present invention, the electric connection cord can be held and stored in the cord holder, so that the electric connection cord will not be damaged or tripped over.

The cord holder can be easily manufactured by extrusion molding. Furthermore, since the cord holder can be mounted on one side of the body of the heating device, the work is extremely easy, and since it is removable, it can be provided on any side of the body of the warming device.

Further, since the electrical connection cord can be pulled out from the cord pull-out portion in the middle part of the cord holder, retention can be considered depending on the position of the console in the room. It has the option of being folded back for storage and retention depending on the length of the electrical connection cord.
