Abstract

PURPOSE:To remove effectively the smoke which is produced in a calcination chamber by installing a catalyst and heating device at a section in an exhaust gas channel consisting of an exhaust gas cylinder that communicates with the calcination chamber and generating an ascending air flow by the heating device in order to make good the air flow in the exhaust channel. CONSTITUTION:A catalyst 18 and a heating device 19 are installed in the inside of an exhaust gas cylinder 17 that communicates with a calcination chamber 15. The temperature in the calcination chamber 15 reaches high temperature by energizing a heater 14 electrically and an object to be cooked is cooked, and the generated smoke is led to the exhaust gas cylinder 17. And then the smoke makes contact with a multihole catalyst 18. At this time the catalyst 18 is kept at high temperature by the heating device 19 and the smoke that passes through the holes of the catalyst 18 is separated to carbon dioxide and water. And, by the heat of the smoke, an ascending air flow is generated and the air in the exhaust cylinder 17 is led to the exhaust gas section 16 smoothly. Accordingly even if the resistance in flow channel becomes large by the catalyst 18, the air flow is smooth and the smoke is effectively removed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a heating cooker such as an induction heating cooker.
This invention relates to a built-in heating cooker that is used by being built into furniture or the like.

BACKGROUND OF THE INVENTION In recent years, market demands have been changing for heating cookers built into kitchen furniture such as system kitchens to have clean heating surfaces and safer surfaces.

Traditionally, built-in heating cookers have been mainly gas-powered, but in recent years there has been an increase in electric-powered appliances due to safety concerns. However, in the case of electric heating cookers that are considered to be the safest and cleanest at present and are used by being built into the top plate of kitchen furniture, the exhaust air from the baking chamber is routed directly to the outside of the cooker by configuring an exhaust path with a cylinder, etc. It was being exhausted.

In addition, built-in heating cookers require a long exhaust path, and installing a catalyst in the exhaust path increases flow path resistance, which tends to reduce exhaust volume with natural exhaust.

Problems to be Solved by the Invention In such conventional built-in heating cookers, the surface of the heating part of the cooker is clean and has no unevenness, so there is no problem, but when grilling fish etc. in the baking chamber, There was a problem in that smoke was generated and the exhaust part got dirty, ruining the otherwise clean heating cooker.

Moreover, in the case of a built-in heating cooker, the exhaust path, except for the inside of the baking chamber, is constructed in such a way that the user cannot easily clean it. In addition, built-in heating cookers require a long exhaust path, which increases flow path resistance, which reduces the exhaust amount with natural exhaust, and installing a catalyst can cause other problems (for example, the front door of the firing chamber). There was a problem that the leakage of smoke and hot air, etc., occurred, which had the opposite effect.

The present invention solves the above problems and aims to provide a safe and clean built-in heating cooker.

Means for Solving the Problems In order to achieve the above-mentioned objects, the present invention enables smooth exhaust gas even if a catalyst and a heating device are installed in a part of the exhaust path of the firing chamber.

Operation With the above-described configuration, the present invention installs a catalyst and a heating device in a part of the exhaust path of the firing chamber, removes smoke generated from the firing chamber, does not pollute the exhaust section, and uses the heating device to generate an upward air current. , which can improve the flow of air within the exhaust path.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIG. 1, FIG. 2, and FIG. 3.

In the figure, 1 is the top plate of the kitchen furniture, and the top plate opening 2
have. Reference numeral 3 denotes an upper unit of the cooking device main body 4, which is attached to the top plate opening 2 from above and electrically connected to the lower unit 5. The upper unit 3 has a heat-resistant cooking plate 6 on the upper surface and a plurality of induction heating coils 7 below it.
a, 7b, and 7c, and the cooking plate 6 includes a coil T&.

Finish, draw a circular pattern so that it is located above 7c,
It is fixed by an outer frame 8. In addition, the induction heating coil 7
a, 7b, and 7c are electrically connected to the lower unit 6. 9 is a first cooling fan motor that cools the induction heating coils 7a, 7b, and 7c, and 10 is the induction heating coil 7a, 7b.

7C and the bottom plate holding the first cooling fan motor 9 form a housing of the upper unit 3.

Inside the lower unit 5 are the induction heating coils 7a, 7b, 7c and the first cooling fan motor 9.
a control circuit 11 that drives the switching element 12 of the switching element 12, a second cooling fan motor 13 that cools the control circuit 11, a firing chamber 16 containing a heater 14 shown in FIG. It is composed of an exhaust pipe 17 that connects a hole provided in a part and an exhaust part 16 of the upper unit 3, and the exhaust pipe 17 has a catalyst 18 and a heating device 1 inside.
9, and is configured to be separated from the firing chamber 15. There is an operation section 2 on the front of the lower unit 6.
o and an intake section 21 of the lower unit 6, and an exhaust section 22 of the lower unit 5 is provided at the rear of the lower unit 5. Further, the operating section 20 is configured in a storage format that allows the operating section to be mounted by hanging from a surface 23, and an upper surface section 24 that is located approximately at right angles thereto and enters into the main body when stored.
A switch operation section 26 is provided at the. Reference numeral 26 denotes an intake section of the first cooling fan motor 9 provided in the upper unit 3 and communicates with the exhaust section 16 thereof.

27 is a cooking pot placed on the cooking plate 6; 28
is a wiring that electrically connects the upper unit 3 and the lower unit 6. Reference numeral 29 denotes a button provided on the operation unit mounting surface 23, and is provided so that when the button 28 is operated, the operation unit 2o is exposed.

In the above configuration, to explain the operation, the operation section 20 provided on the front surface of the lower unit 5 is normally stored so that the operation section mounting is flush with the surface 23 when not in use, as shown in FIG. By operating the use button 29, the state shown in FIG. 2 is achieved. Then, by operating the switch operation section 26, a signal is issued to drive the control circuit 11, which heats the induction heating coils 7a, 7b, 7c built in the upper unit 3, and heats the firing chamber 15.
The heater 14 built into the unit is energized.

When the induction heating coils 7a, 7b, 7c are heated and the cooking pot 2 is placed on the top surface of any of the induction heating coils 7a, 7b, 7c, the cooking pot 27 is heated.
It is heated by the magnetism emitted from 7c.

On the other hand, when the heater 14 built in the baking chamber 15 is energized, the temperature inside the baking chamber 15 becomes high and the food such as fish is baked. The removed smoke is generated and fills the firing chamber 15, but is led to the exhaust pipe 17. It comes into contact with a catalyst 18 in a porous tank provided in the middle of the exhaust path. At this time, the catalyst 18 is kept at a high temperature by a heating device 19, and the smoke passing through the holes of the catalyst 18 is separated into carbon dioxide and water. It is something that can be smoothly guided in the direction.

Effects of the Invention As is clear from the above embodiments, according to the present invention, in a heater where the exhaust path from the firing chamber is long, such as a built-in heating counter, a catalyst is installed to increase the flow path resistance. However, it is possible to provide a built-in heating cooker that smooths the flow of air in the exhaust path, removes smoke generated from the firing chamber, and does not pollute the exhaust section.

In addition, by making the exhaust stack separable from the firing chamber, it is easy to replace the catalyst, heating device, etc. when something goes wrong, and it is also easy to switch when manufacturing different products with or without a smoke removal function. Moreover, it also has the effect of improving production efficiency.
