FIG. 1 is a perspective view of a heating conditioner according to an embodiment of the present invention. As shown in FIG. 1, the heating conditioner 10 is a microwave oven with an oven function, and a heating chamber 17 is provided in the opening deep to store and heat the food to be heated.

The heating chamber 17 has a ceiling, a bottom surface, a rear wall, a left wall, and The right wall has five faces in total, and the outer side of the heating chamber 17 is covered with a cover 20. The opening in front of the heating chamber 17 is provided with a door 18 that allows one side below the opening to rotate on the axis.

In the following description, the opening side of the heating chamber 17 will be referred to as the front, the depth of the heating chamber 17 will be referred to as the rear, and the right and left sides will be referred to simply as the right and left sides from the front to the rear.

The left and right side walls of the heating chamber 17 are provided with three pairs of tray rack sections (the tray rack section 16a, the tray rack section 16b, and the tray rack section in order from the top) for supporting a metal conditioning tray that carries a heated object, that is, food. 16c).

On the right side wall of the heating chamber 17, the lighting holes 11a, which are the first lighting holes, and the lighting holes 11b, which are the second lighting holes, are individually provided above and below the shelf portion 16a, and are closer to the opening than the rear wall of the heating chamber 17. s position.

When the conditioning disk 12a is provided in the disk rack portion 16a, the lighting holes 11a and 11b are arranged so as to face the upper space 17a and the lower space 17b of the conditioning disk 12a individually.

FIG. 2 is a perspective view showing a state where the heating conditioner of the embodiment has removed the cover 20.

As shown in FIG. 2, the illuminating device 30 a and the illuminating device 30 b are individually installed so that they cover the lighting hole 11 a and the lighting provided at a position closer to the opening than the rear wall of the heating chamber 17 from the right side wall of the heating chamber 17. With holes 11b.

As shown in FIG. 1, when the conditioning disk 12a is disposed on the disk rack portion 16a, the space 17a above the conditioning disk 12a is illuminated by the lighting device 30a, and the space 17b below the conditioning disk 12a is illuminated by the lighting device 30b.

The door 18 is provided with a window 19, which can be viewed through the window 19 during conditioning. Inside the heat chamber 17.

Since the illuminating device 30a and the illuminating device 30b have basically the same structure, only the illuminating device 30a will be described below.

3 and 4 are perspective views and cross-sectional views of an illuminating device used in the heating conditioner of this embodiment.

As shown in FIG. 3, the lighting device 30 a includes an LED 15, an LED substrate 14 on which the LED 15 is mounted, and a case 13 that houses the LED substrate 14.

The casing 13 is disposed outside the right wall of the heating chamber 17. The casing 13 includes an opposing surface 13 a facing the outer side surface of the right side wall of the heating chamber 17. The opposite surface 13 a is surrounded by a side wall 13 b of the casing 13.

The opposing surface 13a has a recessed portion near the center thereof. A through hole is provided at the bottom of the recessed portion of the opposing surface 13 a to expose the LED 15. The concave portion of the opposite surface 13 a is provided with a reflecting portion 13 c so as to surround the LED 15.

Since the LED substrate 14 is disposed at the bottom of the recessed portion of the opposite surface 13 a, the lighting device 30 a is surrounded by the LED substrate 14, the side wall 13 b, and the opposite surface 13 a, and has a space in which the LED 15 is disposed inside the housing 13. The housing 13, particularly the reflecting portion 13c, has a light color such as white, gray, or the like.

As shown in FIG. 4, the angle formed by the LED substrate 14 and the reflecting portion 13 c is different depending on the situation. In this embodiment, the angle 22a formed by the reflective portion 13c above the LED 15 and the LED substrate 14 is approximately a right angle, and the angle 22b formed by the reflective portion 13c below the LED 15 and the LED substrate 14 is larger than the angle 22a.

With the above-mentioned reflecting portion 13c, it is possible to increase the amount of light that passes through the illumination hole 11a and enters the heating chamber 17.

Furthermore, when the conditioning disk 12a is provided on the disk rack portion 16a, the LED 15 The light reflected by the square reflection portion 13c will illuminate the area closer to the illumination hole 11a of the conditioning disk 12a (that is, the area at the right end of the conditioning disk 12a), and the light reflected by the reflection portion 13c below the LED 15 will illuminate the conditioning disk 12a. The area far from the lighting hole 11a (that is, the area at the left end of the conditioning plate 12a).

Therefore, according to this embodiment, a wide area can be illuminated with light from the LED 15 in the left-right direction of the conditioning disk 12a.

In the front-rear direction of the heating chamber, similarly, the angle formed by the LED substrate 14 and the reflecting portion 13c is different depending on the situation. That is, the angle formed by the reflective portion 13c in front of the LED 15 and the LED substrate 14 is approximately a right angle, similar to the angle 22a, and the angle formed by the reflective portion 13c behind the LED 15 and the LED substrate 14 is substantially the same as the angle 22b.

As described above, this is because the lighting hole 11 a is provided closer to the opening than the rear wall of the heating chamber 17.

Thereby, the light reflected by the reflecting portion 13c in front of the LED 15 will illuminate the area at the rear end of the conditioning disk 12a, and the light reflected by the reflecting portion 13c at the rear of the LED 15 will illuminate the area at the front end of the conditioning disk 12a.

According to this embodiment, a wide area can be illuminated by the light from the LED 15 in the front-back direction of the conditioning disk 12a.

In this way, LEDs with stronger directivity than incandescent light bulbs can be used to illuminate the upper and lower spaces of the heating chamber defined by the conditioning panel to all corners, so that the recognition of food is more than that of the conventional heating conditioner. Promotion.

Regarding the lighting device 30b, when the conditioning plate 12b is provided on the bottom surface of the lighting hole 11b and the heating chamber 17, or on the rack portion 16c, the lighting device 30b is spaced from the lighting hole 11b. The distance from the conditioning panel 12b is different from that of the lighting device 30a. Therefore, the angle of the reflecting portion 13c considering this dissimilarity can be selected.

The different advantages of this embodiment include the following.

In this embodiment, the existence of the internal space of the lighting device 30a makes it difficult for the heat inside the heating chamber 17 to be directly transmitted to the LED 15 and the safety of the product can be guaranteed.

In addition, since the reflecting portion 13c has a light color in the housing 13, the light reflection efficiency can be improved.

An example of the conditioning operation of the heating conditioner 10 configured as described above will be briefly described below.

The heating conditioner 10 is a microwave oven with an oven function. At least one of microwave, radiant heat, hot air, and steam is supplied to the heating chamber 17 to condition the object to be heated in the heating chamber 17. Therefore, the heating conditioner 10 includes a microwave generating portion (not shown), an upper heating unit, a convection heater unit, and a steam generating portion.

The microwave generator supplies microwaves generated by a magnetron provided below the bottom surface of the heating chamber 17 into the heating chamber 17 from below. The upper heating unit is a sheathed heater provided on the ceiling of the heating chamber 17, and heats the inside of the heating chamber 17 from above with radiant heat. The convection heating unit uses a heater and a fan provided deep in the rear wall of the heating chamber 17 to circulate hot air into the heating chamber 17 through a hole provided in the rear wall of the heating chamber 17.

For example, when the heating conditioner 10 is used to bake a cream roll cake, an oven function that activates only a convection heating unit is activated. In the oven function, The hot air from the convection heating unit uniformly heats the dough 12a individually arranged on the rack part 16a and the rack part 16c and the dough formed on the conditioning dish 12b into small and round dough.

During heating, light from the lighting device 30a will illuminate the space 17a above the conditioning plate 12a to each corner, and light from the lighting device 30b will illuminate the space 17b below the conditioning plate 12a to each corner. Therefore, even if the dough is far from the lighting device 30a and the lighting device 30b and is placed on the left corner of the conditioning plate 12a and the conditioning plate 12a, the user can recognize the degree of baking.

In the present embodiment, the lighting holes 11a and the lighting holes 11b are individually provided above and below the uppermost shelf portion 16a of the three shelf portions provided on the right wall. However, it is not limited to this, as long as a plurality of spaces in the heating chamber 17 divided by one or more conditioning plates can be illuminated.

For example, a total of four lighting holes may be provided between the ceiling of the heating chamber 17 and the three rack sections and the bottom surface of the heating chamber 17. The lighting hole may be provided on the left wall instead of the right wall, or may be provided on the left and right side walls.

In the present embodiment, the lighting holes 11 a and the lighting holes 11 b may be provided closer to the opening than the rear wall of the heating chamber 17. However, the lighting holes 11 a and the lighting holes 11 b may be provided closer to the rear wall than the opening of the heating chamber 17.

At this time, for example, if the angle formed by the reflection portion 13c behind the LED 15 and the LED substrate 14 is substantially the same as the angle 22a, the angle formed by the reflection portion 13c in front of the LED 15 and the LED substrate 14 is the same as the angle 22b. It may be larger than the angle 22a.

Similarly, the lighting holes 11 a and the lighting holes 11 b may be provided at the same distance from the opening of the heating chamber 17 as the distance from the rear wall of the heating chamber 17. At this time, the angle formed by the reflective portion 13c in front of the LED 15 and the LED substrate 14 and the angle formed by the reflective portion 13c in the rear of the LED 15 and the LED substrate 14 may be made equal.

That is, in the front and rear directions of the heating chamber 17, according to the positions of the lighting holes 11a and the lighting holes 11b, if the angle formed by the reflecting portion 13c and the LED substrate 14 is appropriately set, the same configuration as in the present embodiment can be obtained. effect.

However, even when the height of the lighting hole 11a is higher or lower than that of the present embodiment, the situation that the lighting device 30a is illuminated from above the conditioning plate 12a does not change. Therefore, in the up-down direction of the heating chamber 17, regardless of the position of the lighting hole 11a, the angle formed by the reflective portion 13c below the LED 15 and the LED substrate 14 is generally greater than the angle formed by the reflective portion 13c above the LED 15 and the LED substrate 14. To be bigger.

In this embodiment, two lighting devices each having a housing and an LED substrate are individually provided in the first lighting hole 11a and the second lighting hole 11b. However, the two illuminating devices of this embodiment may be constituted by one casing and one LED substrate.

That is, in this configuration, one case is provided with two recessed portions each having a reflection portion, and is individually exposed from the bottom of the recessed portions corresponding to two LEDs mounted on one LED substrate. According to this configuration, since the number of components and manufacturing work items can be reduced by the embodiment of the present embodiment, the cost can be reduced.

[Industrial availability]

As explained in detail above, according to the present invention, specific heat LEDs with more directional bulbs will illuminate the upper and lower spaces of the heating chamber defined by the conditioning panel to all corners, so that the visibility of the food can be improved more than the conventional heating conditioner.

Therefore, the present invention can be applied to an oven, a microwave oven with an oven function, and the like that are used for home or business use to adjust the state of the heating chamber inside the conditioning panel.
