The first insertion portion 43 and the bent portion of the second insertion portion 44 is in contact with the lower portion of the insulating member 30, so that the first heating wire 41 and The second heating wires 42 are connected to each other, thereby allowing the wrapping paper 13 stacked on the food container 12 to be heat-sealed in a hollow closed curve shape to the edge of the food container 12.

Alternatively, as shown in FIG. 6, the first inserting portion 43 and the second inserting portion 44 facing each other may be spaced apart from the lower portion of the insulating member 30.

In this case, the first heating wire 41 and the second heating wire 42 are spaced apart from each other at the lower portion of the insulating member 30, thereby stacking the wrapping paper 13 stacked on the food container 12. The rim of the container 12 may be heat-sealed in the shape of a hollow open curve rather than a hollow closed curve.

In this case, the wire 70 is electrically connected to both the first inserting portion 43 and the second inserting portion 44 spaced apart from each other, so as to both the first heating wire 41 and the second heating wire 42. Supply power.

As the method in which the wire 70 is electrically connected to the first heating wire 41 and the second heating wire 42, as shown in FIG. 6A, the first insertion part 43 and the second heating wire 42 are electrically connected. Insertion portion 44 may be directly connected to the wire 70, it may be electrically connected through the housing 51 made of a conductor material as shown in Figure 6 (b).

In addition, the connection member 50 may further include a cooling fin 55 protruding from the outer circumferential surface of the housing 51.

By the cooling fins 55, heat generated by electricity flowing through the heating wires 40 and the wires 70 may be more easily radiated to the outside of the housing 51.

In addition, in the present invention, the first heating wire 41 and the second heating wire 42 are coupled by the connecting member 50 without welding and are easily assembled.

In particular, since the heating wire 40 and the electric wire 70 can be detachably coupled to the connection member 50, not only assembly but also repair is easy.

Meanwhile, the present invention may further include a temperature sensor 56 and a controller 60.

The temperature sensor 56 is mounted to the connection member 50 to detect the temperature of the connection member 50.

To this end, the connecting member 50 is made of a conductor.

More specifically, the temperature sensor 56 is mounted to the housing 51 to detect the temperature of the housing 51 made of a conductor.

The controller 60 controls on / off of the power supply unit according to the temperature of the connection member 50 sensed by the temperature sensor 56.

The temperature sensor 56 and the control unit 60 may prevent the heating wire 40 from being overheated to cause a fire or the like.

In addition, the heating wire 40 may be formed in one band shape as shown in FIG. 7.

At this time, the first inserting portion 43 and the second inserting portion 44 are bent and formed at both ends of the heating wire 40, and the first inserting portion 43 and the second inserting portion 44 facing each other. Is inserted into the mounting hole 53 is to be connected to the wire (70).

In this case, the first inserting portion 43 and the second inserting portion 44 may be inserted into the same connecting member 50, may be inserted into a separate connecting member 50, the applied current In order to move from the first inserting portion 43 to the second inserting portion 44, the first inserting portion 43 and the second inserting portion 44 may be spaced apart from each other.

At this time, the housing 51 is preferably made of an insulator so that the first inserting portion 43 and the second inserting portion 44 are not electrically connected to each other.

By the heater structure of the present invention as described above it is possible to more easily assemble the heating wire 40, and also in case of breakage of the heating wire 40 can easily replace only the heating wire 40, the heating wire 40 and the wire 70 ) Is connected without being bent by the connecting member 50, it is possible to prevent overheating.
