Description

[Detailed explanation of the idea] The present invention relates to a built-in electric range.

Generally, in the stove part, a pot containing water, etc. is placed on top of the heater placed on the top plate, so the top plate is placed downward, but this invention allows this load to be transferred to the back plate with a cylinder. The purpose is to share the work and eliminate the amount of bending of the top plate.

The second purpose of this invention is to connect the hole in the center of the top plate and the hole in the back plate directly below this hole by sealing it with a cylinder, effectively discharging the roaster exhaust to the outside. , to prevent hot air from leaking to heaters, etc.

The third purpose of the present invention is to prevent thermal distortion and thermal expansion changes in the top plate caused by heating the stove part by using a back plate connected by a cylinder.

In other words, although the heater is held horizontally,
The top surface of the top plate is slightly convex upward, and the bottom surface of the back plate is convex slightly downward, and in this form the two are connected with a tube.

Because of this, when heated with a convex top plate like the former, for example, the top plate tends to swell up into a convex shape due to thermal expansion, and the cylinder acts to pull up the back plate.

However, since the back plate is convex downward, it has a very large resistance to being pulled up, and in fact, thermal expansion of the top plate is prevented.

Conventionally, when a roaster was not vented from the stove, a special hole had to be made in the sink for an exhaust port, which was cumbersome and did not prevent thermal distortion of the top plate.

In addition, if the exhaust gas is discharged from the back plate of the stove part into the stove part and then exhausted to the outside through a hole in the heater saucer, etc., it is easy to install the machine and process the parts, but the exhaust heat may have a negative effect on the heater. In addition, since the top plate was not supported by a tube or the like, it was not possible to prevent thermal distortion.

Furthermore, since there is no connection through a tube, the load can only be received by the top plate, so it is uneconomical to increase the thickness of the top plate to increase its strength.

The present invention solves the above-mentioned drawbacks of the conventional technology and achieves the intended purpose.Examples of the present invention will be described below.

In FIGS. 1 and 2, 1 has a plurality of heaters 3, 4, and 5 attached to the top surface of the top plate 2, and a sink 7.
This is a stove part that is fitted from above into a hole 9 provided in a top plate 8.

A box-shaped back plate 10 having an open top and having approximately the same size as the top plate 2 is fixed to the back surface of the top plate 2 at a peripheral plate portion of the top plate 2.

A hole 11 is provided in the center of the top plate 2, and this hole 1
A hole 12 is also provided in the back plate 10 directly below the hole 1.
1 and the hole 12 are connected by a cylinder 13, and the cylinder 13 is fixed to the hole 11 by a screw 14 and to the hole 12 by a screw 15, both from above.

The top surface 16 of the top plate 2 is slightly convex and bulges upward, and the bottom surface 17 of the back plate 10 is conversely slightly convex and bulges downward.

Even though the upper surface 16 of the top plate 2 is swollen in this way, the plurality of heaters 3, 4, and 5 are configured to be horizontal. Here, heater 3,
When the top surface 16 thermally expands due to the heating of steps 4 and 5, it tries to swell further upwards, but similarly, the bottom surface 17 also tries to swell further downwards due to thermal expansion, and the bottom surface 17 of the back plate 10, which swells downward, becomes a cylinder. 13 to prevent this bulge.

On the other hand, the roaster part 18 is installed from the front into a hole 20 provided in the front surface 19 of the sink 7.

The roasting chamber 21 is provided approximately at the center of the operation panel 22 on the front side of the roaster section 18, and an exhaust port 24 protruding from the rear upper surface 23 of the roasting chamber 21 is connected to the hole 1.
It is located in a position facing 2.

A chimney 25 that is thicker than the exhaust port 24 and thinner than the cylinder 13 is fitted into the exhaust port 24.
The upper end of the hole 5 is configured to extend close to the hole 11.

Since it is configured as described above, the roaster section 18
The exhaust heat of
4, 5, etc., the stove part 1 is not overheated.

On the other hand, the top plate 2 of the stove part 1 is connected to the back plate 10 by a cylinder 13, and is strong even if a load from a pot or the like is applied to the stove part 1.

Furthermore, the distortion due to thermal expansion of the upper surface 2 of the top plate 1 is
The bottom surface 17 of 0 is blocked through the cylinder 13, and the horizontality of the top surface 2 and the top surfaces of the heaters 3, 4, and 5 is maintained in a good state.

Moreover, if the top surface is slightly bulged upward and the bottom surface is bulged slightly downward, this thermal expansion inhibition effect will be significant.

That is, if the top surface 2 and the bottom surface 17 are completely flat, it is not constant whether the thermal strain of the top plate 1 occurs upward or downward, and the strain prevention force by the bottom surface 17 is also small.

As described above, according to the present invention, a box-shaped back plate is provided on the back side of the flat top plate of the stove section, and a box-shaped back plate is provided that covers the entire back surface of the top plate, and a hole is provided approximately in the center of the top plate. A hole is also provided in the back plate to correspond to this hole, and a tube is connected between these holes, and the exhaust port of the roaster section is exposed to this tube.With this configuration, the roaster The waste heat of the parts can be efficiently discharged to the outside through the cylinder.
In addition, even if a load from a pot, etc. is applied to the top plate of the stove, this load is also supported by the back plate via the cylinder, so any weaknesses in the top plate can be reliably reinforced with the back plate. The top surface is slightly convex upward, and the bottom of the back plate is slightly convex downward, so distortion caused by thermal expansion of the top plate can be canceled out through interaction with the back plate. As a result, the levelness of the top plate can be maintained well, so that it is possible to prevent food items placed on the heater on the top plate from tilting.
