“A” is formed by cutting and raising a part of the intake duct 20 downward, and two mounting holes are formed in the mounting portion 20a. In addition, as shown in FIG. 4, the first base portion 22a of the main body portion 22 is integrally formed with columnar portions 22d located at both ends. An engaging portion 22e is integrally formed with each of the columnar portions 22d, and the connector 21 has the engaging portions 22e as shown in FIG.
As the mounting part 2 is pushed into the mounting hole of the mounting part 20a.
It is attached to 0a.

In the intake duct 20, as shown in FIG.
The cutout portion 20b is formed. The width dimension W1 (horizontal dimension) and W2 (dimension direction dimension) of the cutout portion 20b are smaller than the diameter dimension R of the light bulb portion 24a and larger than the diameter dimension r of the cylindrical portion 24b, as shown in FIG. Is set, the cylindrical portion 24b is inserted into the cutout portion 20b,
The light bulb portion 24a is located inside the intake duct 20.

Then, from the power supply circuit to the resetable terminal 2
3 and the tab terminal 24d, power is supplied to the light bulb portion 24a, and when the light bulb portion 24a emits light, the intake duct 20
Light is projected from the inside into the cooking chamber 14 through the air outlet, and the inside of the cooking chamber 14 is illuminated. In the inside lamp 24, the tip of the light bulb portion 24a is substantially in contact with the inner surface of the intake duct 20 in the mounted state.

Next, the procedure for mounting the interior lamp 24 will be described. First, as shown in FIG. 4, each tab terminal 24 d of the interior lamp 24 is inserted into the insertion port 22 c of the connector 21 and connected to the resector pull terminal 23. Next, as shown in FIG. 3, the cylindrical portion 2 of the interior lamp 24 is inserted into the cutout portion 20b of the intake duct 20.
Insert 4b.

Then, as the light bulb portion 24a is brought into contact with the ceiling portion of the intake duct 20, each engaging portion 22e of the connector 21 is positioned in the height direction with respect to the mounting hole of the mounting portion 20a. Push the engaging portion 22e into the mounting hole. Then, as shown in FIG. 1, the end surface of each engaging portion 22e engages with the peripheral edge portion of the mounting hole, and each columnar portion 22d and engaging portion 22e.
The mounting portion 20a is sandwiched between them. As a result, the connector 2
1 is attached to the attachment portion 20a in a state where it is not pulled out.

According to the above embodiment, the inside lamp 24 is attached to the intake duct 20 via the connector 21. For this reason, if the shape of the connector 21 is varied and the connector 21 is selectively used according to the mounting site, etc., the interior light 24
There are only a few variations. Therefore, the interior light 24
Can be standardized, which simplifies the management of the inside lamp 24. At the same time, when exchanging the interior lamp 24, it is not necessary to search for a suitable interior lamp 24, so that the serviceability is improved. Since the connector 21 is rarely replaced, increasing the variation of the connector 21 does not deteriorate serviceability.

By the way, the conventional interior lamp has a resin portion 24c.
Was formed of a hard resin such as phenol. Therefore, vibration caused by the air driver when the flange is screwed and vibration caused by opening and closing the door 15 are generated by the light bulb portion 24.
There is a risk that the filament of the light bulb portion 24a will be broken due to the transmission to a.

On the other hand, in this embodiment, the connector 21 is provided with the engaging portion 22e, and the connector 21 is attached to the intake duct 20 by pushing the engaging portion 22e into the attachment hole. Therefore, since it is not necessary to use an air driver or the like, it is possible to prevent the filament of the inside lamp 24 from being broken due to vibration during mounting. At the same time, the work of mounting the inside lamp 24 is simplified. Moreover, the main body 2 of the connector 21
2 was made of a relatively soft resin (nylon).
For this reason, vibrations due to opening and closing of the door 15 are absorbed by the main body portion 22 and become difficult to be transmitted to the interior lamp 24. From this point as well, disconnection of the filament is prevented.

The width W1 of the notch 20b into which the cylindrical portion 24a of the interior lamp 24 is inserted is set smaller than the diameter R of the light bulb portion 24a. Therefore, even when both engaging portions 22e of the connector 21 are disengaged from the mounting holes of the mounting portion 20a,
Since the light bulb portion 24a is hooked on the edge portion of the cutout portion 20c, the inside lamp 24 is prevented from falling off. Moreover, since the width dimension W2 of the cutout portion 20b is set smaller than the diameter dimension R of the light bulb portion 24a, the interior lamp 24 is reliably prevented from falling off.

By the way, when the tab terminals 24d and 24d are arranged substantially parallel to each other, for example, when the interior lamp 24 is mounted sideways, both tab terminals 24d are in the same direction in which they can be easily pulled out from the insertion port 23c. Depending on the vibration direction, both tab terminals 24d may come off from the connector 21.
On the other hand, in this embodiment, the tab terminal 24 of the interior lamp 24
The angle between d and 24d was set to about 90 °. For this reason,
Since the direction of easiness of pulling out the one tab terminal 24d with respect to the insertion port 23c is different from that of the other tab terminal, it is difficult for the two tab terminals 24d to come out of the connector 21 no matter which direction the vibration is applied.

In the first embodiment, the interior lamp 2
The angle between both tab terminals 24d of 4 is set to about 90 °, but the present invention is not limited to this. The point is that the angle of both tab terminals 24d with respect to the insertion port 23c is different. Just have to have.

Next, a second embodiment of the present invention will be described with reference to FIGS.
It will be described based on. The same members as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted. Hereinafter, only different members will be described. First, in FIG. 7, the connector 25 is formed by embedding two resector pull-down terminals 23 in a main body 26 made of nylon, and the main body 26 includes a first base portion 26a having a rectangular prism shape, It is composed of a second base portion 26b having a quadrangular prism shape, and a disc-shaped connecting portion 26c connecting the first base portion 26a and the second base portion 26b, and the connecting portion 26c has a hole 26.
d is formed.

Each resector pull-out terminal 23 is accommodated in the cavity when the main body 26 is molded (so-called insert molding), so that the first base portion 26a and the second base portion 26a
The lead wire 23a of each resector pull-out terminal 23 projects to the outside of the main body portion 26.

An insertion opening 26e is formed in each of the first base portion 26a and the second base portion 26b, and the interior light 2
When mounting 4, the tab terminals 24d of the interior lamp 24 are first inserted into the insertion openings 26e and connected to the resector pull terminals 23. Next, as shown in FIG.
The screw 27 is fastened to the ceiling plate of the inner box 13 (corresponding to the fixed portion) through the hole 26d.

The inner box 13 is provided with a window 13a made of punching metal or the like, and the interior lamp 24 illuminates the inside of the cooking chamber 14 through the window 13a. Further, the tab terminals 24d, 24d of the interior lamp 24 are arranged substantially parallel to each other.

According to the above-described embodiment, since the main body 26 of the connector 25 is made of elastic nylon resin, when the connector 21 is screwed, vibration from the air driver is absorbed by the main body 26. To be done. For this reason, it becomes difficult for vibration to be transmitted to the interior lamp 24, so that the filament is prevented from being broken.

In the second embodiment, the interior lamp 2
Although the four tab terminals 24d, 24d are arranged substantially parallel to each other, the present invention is not limited to this, and they may be arranged substantially at right angles as in the first embodiment. In the case of this configuration, since the number of variations of the interior lamp 24 can be further reduced, the management of the interior lamp 24 is further simplified and the serviceability is further improved. Further, in the above-mentioned first and second embodiments, the recessable terminal 23 is embedded in the main body portions 22 and 26 by insert molding, but the present invention is not limited to this.
For example, it may be inserted later.

In the first and second embodiments, the main body 22 of the connector 21 and the main body 26 of the connector 25 are made of nylon, but the present invention is not limited to this. However, in order to absorb the vibration,
Instead of using a relatively hard resin such as phenol, it is better to use a resin having elasticity such as polyethylene. Further, although the present invention is applied to the microwave oven in the first and second embodiments, the present invention is not limited to this, and is applied to, for example, a toaster cooker, an oven cooker, a grill cooker, and the like. Is also good.
