Description

The present invention relates to a cooking device such as an induction cooking device,
The present invention relates to a built-in type heating cooker used by being incorporated in furniture or the like.

2. Description of the Related Art Conventionally, in a heating cooker having a heating chamber such as a roaster inside, an exhaust pipe 2 is connected to a heating chamber 1 in order to discharge smoke such as grilled fish as shown in FIG.

Problems to be Solved by the Invention In the conventional configuration, since natural exhaust is used, oily smoke and the like remain at the tip 3 and the exhaust port 4 of the exhaust pipe 2 and adhere to the dirt. Was causing stains on the kitchen walls.

The present invention has a heating chamber such as a roaster and has a plurality of induction heating coils, and in order to realize a built-in type heating cooker, in consideration of the above-described conventional problems, a first object is to In addition, smoke from the heating chamber is smoothly discharged, and dirt around the exhaust pipe is dispersed and discharged to the outside.

A second object of the present invention is to discharge exhaust gas from a heating chamber to the outside more efficiently in a vertically separated heating cooker.

Means for Solving the Problems A first means of the present invention for achieving the first object is a heating cooker main unit having an induction heating coil, a circuit unit for driving the induction heating coil, and a roaster. In this case, the front end of an exhaust pipe led out of the heating chamber faces downward below an exhaust cover that is discharged by a cooling fan provided inside the heating unit.

A second means for achieving the second object is that a second exhaust pipe is detachably provided at the tip of the exhaust pipe of the lower unit.

According to the first means, the oil smoke and the smoke discharged from the heating chamber are mixed with the exhaust air discharged by the cooling fan and are forcibly discharged to the outside. It becomes difficult.

In addition, since the exhaust from the heating chamber of the lower unit is guided to the exhaust cover of the unit by the second means, the exhaust efficiency is improved, and even if the interval between the upper and lower units is changed by the installation work, This has the effect of keeping the exhaust efficiency constant.

Embodiment An embodiment of the present invention will be described with reference to FIGS.

In the figure, the heating cooker main body is composed of an upper unit 7 dropped into an opening 6 of a cabinet 5 and a lower unit 8 installed below the upper unit 7. Upper unit 7
The cooking plate 9 and the induction heating coils 10 and 11 and the first
It is composed of a cooling fan motor 12. The lower unit 8 includes a heating chamber 13 such as a roaster, a drive circuit 14 for an induction heating coil, and a second cooling fan motor 15. At the upper part of the heating chamber 13, a discharge cylinder 16 for discharging the inside oil smoke and the smoke exhaust to the outside is fixed, and its tip 17 faces downward under an exhaust cover 18 provided at the rear of the upper unit 7. is there. At the bottom of the upper unit 7, there is an upper unit air inlet 19 facing the first cooling fan motor 12, and in front of the lower unit 8, there is a lower unit air inlet 20. Enables air intake. 12 is heating room 13
The door. Here, while the heating chamber 13 is in use, the first cooling fan motor 12 and the second cooling fan motor
15 is configured to rotate at least one of them.

 Here, the operation of the present embodiment will be described.

When the heating chamber 13 of the heating cooker body is used, the cooking material inside is cooked, and at the same time, the oil smoke and the smoke emission pass through the exhaust pipe 16 and are guided to the tip 17 of the exhaust pipe 16 to be discharged. Go. At this time, since at least one of the first cooling fan motor 12 and the second cooling fan motor 15 of the upper unit 7 is rotating, the smoke is discharged from the tip 17 of the exhaust pipe 16 and the smoke is discharged.
The air is mixed with the cooling air exhausted by the first or second cooling fan 12 or 15, and its concentration is reduced, and is discharged from the exhaust cover 18.

Since the tip 17 of the exhaust pipe 16 is constantly exposed to the cooling air, the residual and adhesion of the oil smoke is small. Further, since the smoke exhausted from the exhaust cover 18 itself has a low concentration and is diffused, the adhesion of dirt to the smoke exhaust portion and the wall surface of the exhaust cover 18 is reduced.

Next, a second embodiment of the present invention will be described with reference to FIGS. In the figure, a second exhaust pipe 22 having an opening at the top and bottom is connected to the tip 17 of the exhaust pipe 16. The second exhaust pipe 22 is detachable and can cope with an interval between the upper and lower units and a positional shift between front and rear and left and right. Specifically, it is inserted from above the exhaust pipe 16 and is supported by the support pieces 23. A directional plate 25 is provided at the tip end 24 of the second exhaust pipe 22 so as to reduce the intrusion of foreign matters and water from the upper part and to make the direction of smoke exhaust backward. Here, as a matter of course, the distal end 24 of the second exhaust pipe 22 is closer to the exhaust cover 18 than the distal end 17 of the exhaust pipe 16.

According to the second embodiment, below the exhaust cover 18,
Since the second exhaust pipe 22 is newly provided, when the smoke exhausted from the heating chamber 13 is discharged from the tip 17 through the exhaust pipe 16, it is directly led to the exhaust cover 18, thereby improving the smoke exhaust efficiency. I do. Further, even if the distance between the upper unit 7 and the lower unit 8 is increased, the smoke can be guided to the exhaust cover 18, and the smoke can be satisfactorily reduced without variation due to installation work or the like.

Since the second exhaust pipe 22 is configured to be detachable, if the upper exhaust unit 22 is detached when the upper unit 7 is incorporated, even if a displacement of the upper and lower units occurs, the second exhaust pipe 22 comes into contact. It will not hurt. Therefore, there is also an effect that the installation work can be improved.

Advantageous Effects of the Invention As is clear from the embodiment, the present invention has a structure in which the exhaust outlet of the exhaust pipe from the heating chamber of the heating cooker having the cooling fan in each of the upper and lower units faces below the exhaust cover of the upper unit. By mixing the smoke discharged from the heating chamber with the cooling air, dirt due to oil smoke adhering to the exhaust part due to the smoke and dirt on the wall surface of the kitchen in which the cooking device is installed is reduced.

In addition, since the second exhaust pipe is detachably provided to the exhaust pipe of the heating chamber, the smoke exhaust efficiency can be improved, the installation work can be improved, and a cooker with less adhesion of dirt can be realized. It is easy to achieve.
