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 considerations. 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 of kitchen furniture, the exhaust air from the baking chamber is constructed with an exhaust path using a tube, etc., and is immediately routed to the outside of the cooker. It was being exhausted.

In addition, the built-in heating cooker has a long exhaust path, which has a large flow path resistance, and natural exhaust tends to reduce the amount of exhaust gas. Furthermore, in built-in heating cookers that use induction heating coils, a cooling fan is used to cool the drive circuit, so the air generated by this cooling fan is passed through the outlet of the smoke exhaust stack installed in the baking chamber. This causes a backflow to the baking chamber, which requires the outlet of the exhaust pipe to be placed outside the cooker where it is not exposed to the wind pressure of the cooling fan.

Problems to be Solved by the Invention In such conventional built-in heating cookers, even in induction heating cookers that are currently considered safe and clean and are used by being built into the top plate of kitchen furniture, etc. There is no problem in that the surface is clean and has no irregularities, but if the outlet of the smoke exhaust pipe installed in the baking chamber ends inside the cooker (below the upper unit exhaust cover), fish etc. When cooking grilled foods, the air generated by the cooling fan flows back into the firing chamber from the exhaust outlet, and the smoke and heat generated leak through the front door of the firing chamber, ruining the clean cooking equipment. There was an issue with the problem.

Additionally, if the outlet of the exhaust pipe was placed directly outside the cooker, where it is not exposed to the wind pressure of the cooling fan, the outlet would become extremely dirty, and in the worst case scenario, food could fall into the outlet and block the exhaust pipe. .

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 object, the present invention is configured such that the direction of the outlet of the smoke exhaust stack provided in the firing chamber is 90 degrees or less with respect to the direction of the wind generated by the cooling fan. It is.

Effect With the above-described configuration, the present invention is configured such that the direction of the outlet of the smoke exhaust stack provided in the firing chamber is 90' or less with respect to the wind direction generated by the cooling fan, and the smoke generated from the firing chamber is directed to the cooling fan. This allows smoke to be evacuated from the outlet without being affected by the wind generated.

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

In FIG. 2, 1 is a top plate of kitchen furniture, and has a top plate opening 2. 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 is electrically connected to the lower unit 6.

The upper unit 3 has a heat-resistant cooking plate 6 on the upper surface and a plurality of induction heating coils tv7a and 7b below.

7C, and the cooking plate 6 has an induction heating coil/
An annular pattern is drawn above 1z7a, 7b, and 7c, and is fixed by an outer frame 8. Further, the induction heating coils 7a, 7c are electrically connected to the lower unit 6. 9 is a first cooling fan motor that cools the induction heating coils/V7a, 7b, and 7a, and 1o is the induction heating coil/L/7a.

This is the bottom plate that holds the first cooling fan motor 9 and the first cooling fan motor 9, and forms the casing of the upper unit 3. Further, inside the lower unit 6, the induction heating coil yv7
a, 7b, 7a and a control circuit 11 that drives the first cooling fan motor 9, and a part of the switching element 1.
2 and a second cooling fan motor 13 that cools the control circuit 11, a firing chamber 16 containing a heater 14 shown in FIG. and an exhaust pipe 17 that connects the heater 14 to the heater 14 at the heating chamber joint part of the exhaust pipe 17.
A catalyst 18 is attached to the upper part.

19 is an operation section provided on the front side of the lower unit 6;
20 is an intake part of the lower unit 6, and 21 is its exhaust part. Further, the operating section 19 is configured in a storage format that allows the operating section to be mounted in and out of the surface 22, and a switch operating section 24 is provided on the upper surface section 23, which is located approximately perpendicular to the surface and enters inside the main body 4 when stored. ing. 26 is upper unit 3
The air intake section communicates with the exhaust section 1e. 26 is a cooking pot placed on the cooking plate 6, and 27 is a wiring that electrically connects the upper unit 3 and the lower unit 5.

Reference numeral 28 denotes a button provided on the surface 22 with the number of operation parts, and is provided so that the operation part 19 is exposed when the button 28 is operated.

Further, 29 is a guide provided near the outlet 30 of the exhaust pipe 17 in order to keep the direction of the air sent from the first cooling fan motor 9 constant and obtain a stable wind speed. The discharge direction of the flue gas air from the outlet 3o is configured to have an elongation of 90' or less with respect to the discharge wind direction of the rectified exhaust air.

In the above configuration, the operation section 19 provided in front of the lower unit 6 is normally stored so that the operation section is mounted flush with the surface 22 when not in use, as shown in FIG. When in use, by operating the button 28, it becomes exposed from the operating section 19 as shown in FIG.

Then, by operating the switch operation section 24, a signal is issued to drive the control circuit 11, and the induction heating coils 1v7a, 7b built in the upper unit 3 are heated.

7C is heated or the heater 14 built into the firing chamber 16 is energized. The induction heating coil a
, 7b, 7c are heated and the cooking pot 26 is placed on the cooking plate 6 on the top surface of the induction heating carp/1z7a, 7b, 7c, the cooking pot 26 becomes the induction heating carp/L/7a +
It is heated by the magnetism emitted from 7c.

When the heater 14 built in the firing chamber 15 is energized,
The inside of the baking chamber 15 is at a high temperature, and cooked foods such as seaweed and fish are baked. The smoke is removed and fills the firing chamber 15, but is led to the exhaust pipe 17 and comes into contact with a porous catalyst 18 provided in the middle of the exhaust path. At this time, the said touch tJX18
is maintained at a high temperature by a heater 14 and decomposes the smoke passing through the pores of the catalyst 18 into carbon dioxide and water. The discharge direction of the exhaust gas air from the outlet 3o is 90 degrees with respect to the direction of the wind generated from the first cooling fan motor 9, which is rectified by the guide 29 provided near the outlet 3o.
Since it is less than 0, it is possible to prevent backflow from the discharge port 30 into the firing chamber 16.

Note that even without the guide 29, if the wind direction near the outlet is constant and the wind speed is stable, the same effect can be obtained, albeit at a different level, by setting the angle between the outlet direction and the wind direction to less than 9o0. It is possible to obtain

Effects of the Invention As is clear from the above embodiments, according to the present invention, even in a heater such as a built-in heating cooker where the exhaust route from the baking chamber is long, the air flow in the exhaust route can be made smooth, It is possible to provide a built-in heating cooker that removes smoke generated from a baking chamber and does not pollute the exhaust section.
