Abstract

PROBLEM TO BE SOLVED: To mount a removed operation control section correctly without inserting an incorrect operation control section by providing a protrusion or a recess, corresponding to a recess or a protrusion, on the inner circumference of a control section provided with a plug part being fitted removably in a plug receiving part. SOLUTION: A recess 3 of appropriate shape is made at a part on the outer circumference of a plug receiving part 2 fixed removably upward at the side end part of an electric floor heater 1 and a protrusion 7 corresponding to the recess 3 is provided on the inner circumference on the side of a control section 5 provided with a plug part 6 being fitted removably in the plug receiving part 2. The recess 3 and the protrusion 7 are disposed at such positions as the plug part 6 can be fitted in the plug receiving part 2 and they have U shape or semi-elliptical shape. Alternatively, the protrusion 7 may be provided on the outer circumference of the plug receiving part 2 and the recess 3 may be provided in the inner circumference of the control section 5.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plug receiving portion attached to a main body of an electric floor heater, in which a plug of a correct control unit of the heater is surely attached / detached, and another different wrong plug is inserted. The present invention relates to a connection portion of an electric floor heater that can prevent insertion.

[0002]

2. Description of the Related Art In recent years, an electric heating element assembly, which is often used in ordinary households, has a front surface formed of a floor plate material, and a heating wire or a sensor wire provided in a heat insulating material such as felt on the lower surface thereof. There are many electric floor heaters on the market, but these floor heaters are sold in the same series by changing the heating area, and the model number is somewhat different, for those with a large floor area Even for small floor areas, the color, shape, nameplate color, etc. of the operation control unit for turning on and off the power supply from the power supply, controlling the amount of power supply and switching the power supply area, etc. are unified. Is usually the case.

[0003] However, when the floor heating device main body and the operation control section are detachable, there are two types of floor heating devices having different heat generating areas in the same home, for example, those of 1,050W and 750W. If the operation control unit is removed and stored when not in use in the summer, and when it is removed in the winter, if the wrong type of operation control unit is inserted into the floor heater body, the parts inside the control unit It may be used in excess of the electrical rating, or the temperature detection set value may be different, and may not reach the user's set temperature, which poses a problem in safety and practical use during use.

[0004]

According to the present invention, the floor heater main body and the operation control unit are detachable, and the wrong operation control unit is not inserted when the removed operation control unit is mounted. Provide an electric floor heater that can be properly mounted on a vehicle and that can be used safely.

[0005]

According to the present invention, a concave or convex portion is provided on the outer periphery of a plug receiving portion attached to the electric floor heater main body and detachable from an upper side or a lateral direction. It is a connector for an electric floor heater in which a convex portion or a concave portion corresponding to the concave portion or the convex portion is provided on an inner periphery of a control portion provided with a plug portion to be fitted.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows a connector which can be detached upward from an electric floor heater in one embodiment. In this embodiment, an appropriately shaped concave portion 3 is provided in a part of the outer periphery of the plug receiving portion 2 which is detachably attached upward at the side end portion of the electric floor heater main body 1, and is attached to and detached from the plug receiving portion 2. A convex portion 7 corresponding to the concave portion 3 is provided on the inner periphery of the control portion 5 provided with a plug portion 6 fitted therein so as to be fitted therein.
Is provided.

The recesses 3 and the projections 7 are respectively arranged at positions where the plugs 6 can be fitted and fitted to the plug receiving portions 2, and the recesses 3 and the corresponding projections are provided. The shape of the portion 7 may be a U-shape as shown in the drawing so as to fit each other, or a shape such as a semi-arc or a semi-ellipse.

Next, FIG. 2 shows a connecting device of another embodiment different from FIG. 1 and has a configuration substantially similar to that of FIG. 1, but in FIG. Convex part 7
Is provided on the inner periphery of the control unit 5, and the concave portion 3 corresponding to the convex portion 7 is provided, so that the plug 6 is securely fitted to the plug receiving portion 2.

Although FIGS. 1 and 2 describe the vertically detachable connecting device of the electric floor heater, FIG.
FIG. 3 shows that the plug section 6 provided inside the control section 5 is detachably attached to the plug receiving section 2 connected to the electric heating element provided laterally at the side end of the electric floor heater main body 1. This describes a fitting to be fitted. In this case, a concave portion 3 is provided on the outer periphery of the plug receiving portion 2 and a convex portion 7 corresponding to the concave portion 3 is provided on the inner periphery of the control portion 5 as in FIG. It is something.

[0010]

In the connector for an electric floor heater according to the present invention described above, the plug receiving portion connected to the electric heater assembly of the floor heater main body, and the control of energization to the electric heater assembly. In the detachable connection tool consisting of a plug part provided in a control part for performing the following, uneven parts respectively corresponding to the plug receiving part and the plug part on the control part side are provided, and the positions and positions of these uneven parts are provided. By making the shape different depending on the type of the floor heater, it is possible to prevent the plug portion from being inserted into the plug receiving portion of another type.

Therefore, when using an electric floor heater having a different heating area in the same house or the like, there is no possibility that the plug of the wrong control unit is inserted into the plug of another heater, and safety is improved. improves.
