Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to an induction heating cooker.

[0002]

2. Description of the Related Art Conventionally, an induction heating cooker of this kind has been shown in FIG. 1 is an induction heating cooker main body, 2 is an outer shell, 3 is a heating coil unit in which a wound heating coil is disposed, 4 is a printed wiring board, 5a is a lead wire pulled out from the inner end of the heating coil, 5b is a lead wire drawn from the outer end of the coil, and 6a is a lead wire 5a.
Is an insulating tube covered with the lead wire 5b, an insulating tube covered with the lead wire 5b, and 7a and 7b are connection terminals arranged on the printed wiring board 6. The lead wire 5a is inserted into the connection terminal 7a, and the lead wire 5b is inserted into the connection terminal 7b.

[0003]

However, in the above-mentioned conventional structure, a member for holding the lead wires 5a and 5b is not provided, and the lead wires 5a and 5b move and come into contact with each other, so that insulation between both terminals can be achieved. Because it may disappear
There is a problem in that it is necessary to cover the lead wires 5a and 5b with the insulating tubes 6a and 6b, which is time-consuming.

In view of the above problems, the present invention holds the lead wires connected to the connection terminals from the heating coil while keeping them apart from each other,
It is an object of the present invention to provide an induction heating cooker capable of achieving insulation between both terminals even if the insulation tube is bad.

[0005]

In order to solve the above problems, an induction heating cooker according to the present invention includes a heating coil unit in which a heating coil is disposed, and a first coil drawn out from one end of the heating coil. A circuit portion having a first connection terminal to which a lead wire is connected and a second connection terminal to which a second lead wire drawn from the other end of the heating coil is connected; the first lead wire; And a holding means capable of holding the second lead wire in a state of being separated from each other.

[0006]

With the above structure, the first lead wire and the second lead wire pulled out from the heating coil do not contact each other but are held in a separated state.

【Example】

(Embodiment 1) Hereinafter, a first embodiment of the present invention will be described with reference to FIG.

In FIG. 1, 11 is an induction heating cooker main body, 12 is an outer shell made of a resin material, 13 is a heating coil unit in which a wound heating coil is disposed, and 14 is a printed wiring board which is a circuit portion. is there. A lead wire 15a is drawn out from the inner end portion of the heating coil, and a lead wire 15b is drawn out from the outer end portion of the heating coil. The lead wire 15a is connected to the protrusions 16a, 16b, 16c as holding means, and the lead wire 15b is The protrusions 16d, 16e, and 16f are hooked in a meandering manner and inserted into the connection terminals 17a and 17b. The lead wire 15a is drawn straight from the inner end of the heating coil to the projection 16a, and the lead wire 15b is drawn straight from the outer end of the heating coil to the projection 16f. The lead wires 15a and 15b are separated from each other. ing.

As described above, according to the first embodiment of the present invention, the lead wire 15a extends over the projections 16a, 16b, 16c, and the lead wire 15b extends over the projections 16d, 16e, 1c.
Since the lead wires 15a and 15b are held in a state of being separated from each other because they are hooked over 6f, respectively, and in addition, the lead wires 15a and 15b are not in contact with each other, and therefore these lead wires 15a and 15b are not in contact with each other. Even if the lead wires 15a, 15b of are not covered with an insulating tube, there is no fear that insulation between both terminals cannot be achieved,
As a result, it is possible to save the labor of covering the insulating tube and reduce the cost by the amount of this insulating tube.

(Second Embodiment) A second embodiment of the present invention will be described below with reference to FIG.

The same parts as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted. Induction heating cooker body 11
Rib 18 made of electrically insulating material and having a c-shaped cross section on the A side of
a and 18b are provided. The ribs 18a and 18b have notches 19a and 19b, respectively, and the protrusions 20 are provided at the centers of the notches 19a and 19b, respectively.
a and 20b are provided, and the cutout portions 19a and 19b are provided.
lead wire 15 into the ribs 18a, 18b through
a and 15b are stored and connected to the connection terminals 17a and 17b.

As described above, according to the second embodiment of the present invention, the lead wire 15 drawn out from the end of the heating coil is used.
Since the a and 15b are housed in the ribs 18a and 18b and the ribs 18a and 18b are connected to the connection terminals 17a and 17b, the lead wire 15 drawn from the heating coil
Ribs 18 even when a and 15b are longer than a predetermined length
It is possible to adjust the lengths of the lead wires 15a and 15b that are exposed without being housed in the ribs 18a and 18b if they are loosened in a and 18b.
The level of the radiation noise emitted from a and 15b can be suppressed to a constant level, and the safety can be improved.

In this embodiment, the ribs 18a and 18b are formed in a c-shape in cross section, but the ribs 18a and 18b are not limited to this. For example, the ribs may be formed in a cylindrical shape to accommodate the lead wire and to extend the lead wire from the other side for connection. The lead wire may be connected to a terminal, as long as the lead wire drawn from the heating coil is housed and the housed lead wire can be connected to the connection terminal.

[0014]

As is clear from the above description, the induction heating cooker of the present invention has the first lead wire drawn from one end of the heating coil and the second lead wire drawn from the other end of the heating coil. Since it is possible to hold the lead wires in a state where they are separated from each other, there is no fear that insulation between both terminals cannot be achieved without covering these lead wires with an insulating tube, and thus it is not necessary to cover the insulating tube, As a result, it is possible to save the labor of covering the insulating tube and reduce the cost by the amount of this insulating tube.

Further, in the case where the first lead wire or the second lead wire can be housed by providing the housing part, even if the lead wire drawn out from the heating coil is longer than a predetermined length, the lead wire is housed. It is possible to adjust the length of the lead wire that is exposed by being loosened inside the storage part without being stored in this storage part, which makes it possible to keep the level of radiation noise emitted from the lead wire constant and safe. It becomes possible to improve the sex.
