Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a toaster oven, and particularly relates to the wiring portion of its electric circuit.

(Prior Art) Conventionally, as shown in FIG. 7, in a toaster oven, a lead wire 2 connected to a heater 1 etc. is engaged with a claw piece 5 formed by cutting and raising a sheet metal bottom plate 4 of a toaster body 3. It has been stopped.

[Problem that the invention attempts to solve]

However, in such a structure, since the bottom plate 4 is made of sheet metal, it is necessary to cover the lead wire 2 with an insulating tube 6 to ensure insulation from the lead wire 2, which is troublesome to assemble and increases costs. I was getting used to it.

The present invention was devised in view of these problems and aims to provide an inexpensive toaster oven that does not require an insulating tube for attaching lead wires, is easy to assemble, and is inexpensive.

[Means for solving problems]

In the toaster oven of the present invention, the toaster main body is divided into a roasting chamber and a device chamber by a partition plate, a heater is provided in the roasting chamber, and an insulating support plate for supporting a wiring board is erected in the device chamber. , attaching a wiring board to the surface of the insulating support plate opposite to the roasting chamber side, and forming a lead wire support part on the insulating support plate;
The lead wires connected to the wiring board are supported on this lead wire support portion.

[Effect]

This invention protects the wiring board by blocking heat from the roasting chamber with an insulating support plate located on the roasting chamber side of the wiring board, and connects the lead wires connected to the wiring board to the leads of the insulation support plate. It is supported by the wire support section.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

11 is the toaster oven main body, this main body 11
As shown in FIG. 2, a pair of left and right main frames 12 and 13 molded from metal plates, an upper reflecting plate 14,
It consists of a lower reflector plate 15, a bottom plate 16, and a pair of left and right side plates 17, 18, and inside this main body 11 there is a housing with an open front, using the right main frame 13 as a partition plate, as shown in FIG. A baking chamber 19 is formed between the pair of main frames 12 and 13, and a device chamber 21 whose front surface is covered with a decorative board 20 is formed between the right main frame 13 and the right side plate 18. There is. Furthermore, an elongated frame plate 22 extending from side to side is provided on the upper front side of the main body 11.

The upper reflector 14 and the lower reflector 15 are fixed between the main frames 12 and 13 by screws, engagement claws, and engagement holes, and the frame plate 2
is fixed with screws to the upper side of an edge 23 formed by bending outward at the front part of the main frames 12, 13.

Furthermore, an upper heater 24 and a lower heater 25 are provided in the upper and lower portions of the roasting chamber 19, and a grilling grate 26 is provided between the upper heater 24 and the lower heater 25.

Next, 27 is a door body, which includes a door frame 28 and this door frame 2.
A glass plate 30 is positioned in the window hole 29 of No. 8 and fitted from the inner side, and a holding plate 31 is fitted into the door frame 27 from the inner side and fixed with screws to hold the glass plate 30. It is configured.

Both sides of the lower part of this door body 27 are rotatably supported by shafts on both sides of the front lower part of the main frames 12 and 13 of the main body 11, and the rotation of the door body 27 causes the roasting chamber to open. 19 can be opened and closed.

In addition, guide holes 32 are formed in the lower parts of the main frames 12 and 13 of the main body 11 in the front and back direction, and a grill grate 26 provided in the roasting chamber 19 so as to be movable in the roasting chamber 19 projects from both rear sides thereof. An engagement shaft 33 is slidably engaged therewith. The grilling net 26 is connected to the door body 27 by an arm (not shown), and is placed inside the roasting chamber 19 when the door body 27 is closed, and when the door body 27 is opened, it is placed inside the roasting chamber 19. It is adapted to protrude forward from the opening 19.

Next, 34 is a waste receptacle, and this waste receptacle 3
4 is constructed by attaching a grip part 36 made of molded synthetic resin to the front end of a dish part 35 made of a metal plate.

A timer switch and the like attached to the inner surface of the decorative panel 20 are housed in the device chamber 21,
Furthermore, the front surface of the decorative board 20 is provided with various operating units such as switches.

Further, in the equipment chamber 21, an insulating support plate 43 on which a wiring board 41 with various electronic components is attached with screws 42 is fixed to the bottom plate 16 with screws, and this insulating support plate 43 is attached to the right main frame. It is arranged parallel to 13. The wiring board 41 is attached to the side of the insulating support plate 43 opposite to the roasting chamber 19 side. Further, side portions 44 covering both sides of the wiring board 41 are provided on both sides of the insulating support plate 43, and the insulating support plate 4 is provided at the bottom of the side portions 44.
3 is formed on the bottom plate 16 with screws. Several lead wires 46 are drawn out from this wiring board 41 to be electrically connected to electrical parts such as heaters 24 and 25 in the roasting chamber 19 and switches attached to the decorative board 20.

The upper edge of this insulating support plate 43 has a lead wire support part 49 having a groove 48 with a narrow entrance 47 and a wide inside.
are formed at two locations by a pair of L-shaped ribs 50 whose tips are bent toward opposite sides.
The several lead wires 46 are inserted and supported within the groove 48 of this lead wire support portion 49.

Next, the operation of this embodiment will be explained.

When assembling the toaster oven, the wiring of the lead wire 46 is carried out by connecting the lead wire 46 to the lead wire support section 49.
The work is easy because it can be completed simply by inserting it into the groove 48.

During roasting, radiant heat is transmitted into the equipment chamber 21 through the right main frame 13 due to heating by the heaters 24 and 25, but since the insulating support plate 43 is interposed between the wiring board 41 and the roasting chamber 19, The radiant heat is blocked by the insulating support plate 43 and does not reach the wiring board 41. Therefore, the adverse effects of heat on various electronic components provided on the wiring board 41 can be avoided.

Since the entrance 47 of the groove 48 is narrow and the inside is wide, the inserted lead wire 46 is difficult to come out of the groove 48 and can be held securely.

In addition, as shown in FIG. 4, the lead wire support part 4
The locking protrusions 51 may be provided protrudingly on both sides of the entrance 47 of the groove 48 of No. 9. In this way, the groove 48
The inner lead wire 46 is caught on this locking protrusion 51,
It will not fall out of the groove 48.

Further, as shown in FIG. 5, the width of the entrance 47 of the groove 48 is made narrower than the diameter of the lead wire 46, and a pair of ribs 50 forming the lead wire support portion 49 are made of elastic synthetic resin. You may. This makes it difficult for the lead wire 46 to come off from the entrance 47 of the groove 48.

Further, the lead wire support portion 49 does not need to be formed by the ribs 50 as described above, and may be formed by directly providing the grooves 48 as described above in the insulating support plate 43 as shown in FIG.

[Effect of idea]

According to the present invention, the lead wire can be locked simply by inserting the lead wire into the groove of the lead wire support, so that the wiring process of the lead wire can be easily performed and assembly is easy.

Furthermore, since the insulating support plate can block radiant heat from the roasting chamber, various electronic components provided on the wiring board are not adversely affected by the heat.
