Abstract

PROBLEM TO BE SOLVED: To provide a cooker which can prevent water entering inside a machine body from outside from reaching an electrical part and a charging part of wiring or the like without deteriorating cooling performance by arranging a waterproof plate above an upper exhaust port arranged in a machine body back face vertical wall, and arranging a waterproof cover on a lower exhaust port. SOLUTION: Partial air sent out to a cooling fan 8 cools an electrical part of a control circuit 4 part, and is exhausted from a lower exhaust port 11 arranged in a machine body back face vertical wall, but a waterproof cover 12 is arranged in this part. The waterproof cover 12 is a cross-sectional U shape, and largely covers the lower exhaust port 11, and prevents an entrance into the inside here even if water splashes away and enters from the outside. On the other hand, a cooling wind to a heating coil 2 is exhausted from an upper exhaust port 16 of a back face. The upper exhaust port 16 is covered with an eaves-shaped large waterproof plate 17 from this upper part. Therefore, water entering a machine body is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an induction heating type heating cooker called an electromagnetic cooker used for business in kitchens such as hotels, restaurants and restaurants.

[0002]

2. Description of the Related Art An induction heater having an output of just over 1 kW, which is used in ordinary households, has a small capacity and therefore generates less internal heat and is less continually used for a long time. Also, since the installation state is also set on a table or a table, there is no problem even if the exhaust outlet is provided on the side surface or the lower part of the body.

However, those used for business use have a large output of 2 to 5 kW or more. In addition, they are often used continuously for a long time, and the internal heat generation is higher than that of a small household machine. In addition, a plurality of units are often arranged side by side in a narrow place, and the environmental conditions are often high in both temperature and humidity. Therefore, a cold air passage of the airframe is required to have a low ventilation resistance in order to improve cooling efficiency. Therefore, it is desired that the cooling air that has cooled the object to be cooled such as the heating coil and the switching element be quickly discharged from the exhaust port provided in the body. Therefore, the exhaust passage is simple and the ventilation resistance is made as small as possible.

[0004] Since the electromagnetic cooker performs cooking using a large amount of water such as boiled food and boiled food, water may be spilled on the top plate of the electromagnetic cooker during cooking. In addition, water is used when cleaning a dirty electromagnetic cooker during cooking. In such a case, although rare, water may be dripped from the upper part of the exhaust port.

[0005] In an exhaust passage form of an electromagnetic cooker used for business, a slit is provided in a vertical wall surface on the back of the machine, and exhaust gas is discharged from the slit to the outside of the machine. In this embodiment, since it is impossible to install the exhaust port of the body by pressing the exhaust port against the wall surface of the kitchen, a tenban that protrudes greatly backward is provided, and a slit is provided behind the tenban. Accordingly, even if the airframe is installed in a state in which the airframe is in contact with a wall surface or another airframe, the cooling air discharged from the exhaust port provided on the rear surface of the airframe is discharged to the outside through the slit at the rear part of the tenvan. . By forming an exhaust port on the tenban surface, even when a plurality of aircraft are installed in an I-land type, there is no protrusion of the exhaust cylinder, and the structure is convenient.

[0006] In order to adopt a structure corresponding to various installation conditions, an exhaust port is provided in the tenvan. Therefore, if water is spilled on the tenvan, it may enter the airframe and adhere to the charged parts of the electrical components and wiring, causing a short circuit or short circuit.

[0007]

As described above, commercial kitchen appliances are used under extremely severe conditions compared with general household appliances. In order to provide a product that can be used without any practical problems even under severe use conditions, the ventilation resistance of the exhaust passage is kept at the same level as the conventional product without increasing, and electrical components and The structure is such that water does not adhere to the charged portion and does not damage electronic circuits and the like.

As a measure for preventing water from entering the airframe through the exhaust port, it is effective to connect an exhaust pipe such that the opening of the exhaust port is provided above the surface to be heated.
Such a method has already been commercialized, and if an exhaust pipe is connected to the rear part of the fuselage, there is a problem in that a large heated object (pan) may be placed on the large body to be heated. In addition, when a plurality of devices are used side by side, there is a problem that it is difficult to work if there is an exhaust pipe when the rear parts are installed together and used in a face-to-face type (I-land type installation).

[0009]

According to the present invention, in order to solve the above-mentioned problems, the exhaust port is provided on the same surface as the surface on which the object to be heated is provided without providing a projection such as an exhaust tube. Further, even if water or the like flows into the airframe, the airflow path has a structure that protects the object to be cooled without reaching the object to be cooled and does not increase the airflow resistance.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION In the exhaust passage for cooling air according to the present invention, the final outlet (exhaust port) is provided in a ten-van which is the same plane as the surface on which the object to be heated is installed. A waterproof plate and a waterproof cover are provided at the upper exhaust port (mainly the cooling air outlet of the heating coil) and the lower exhaust port (cooling air outlet of the electronic components) provided on the vertical wall, and the area of the cooling air exhaust passage is sufficiently secured. Accordingly, the present invention provides an induction-type heating cooker having a structure in which cooling performance is not reduced and water that has entered the inside of the body from the outside does not reach the electrical components and the charged portion of the wiring.

With the above structure, the exhaust port can be maintained on the same surface as the surface on which the object is to be heated without using an exhaust tube, and can be used without difficulty even on a large-diameter object to be heated. Is designed to keep the same level as the conventional product without increasing, and to prevent water from entering from the exhaust port and to prevent damage to the built-in electric components.

[0012]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view from the side, showing a schematic structure of a cooking device according to the present invention. FIG. 2 is a rear perspective view showing details of the exhaust port portion.

In FIG. 1, reference numeral 1 denotes a metal container (for example, a pot or the like) of an object to be heated which is heated by an induction heater. Reference numeral 2 denotes a heating coil that generates a magnetic flux by passing a high-frequency current. Reference numeral 3 denotes a crystallized glass ceramic plate provided between the heating coil 2 and the object 1 to be heated.
This prevents water and oil, foodstuffs being cooked, garbage, and the like from entering electric components such as the heating coil 2 and allows the magnetic field lines to pass.

A metal container 1 which is a body to be heated is placed on a ceramic plate 3. 3 'is a ceramic plate 3
Tenban incorporating the 4 is a control circuit, 5
Reference numeral denotes a control panel section provided with an operation switch 6, a thermal power adjustment switch 7, and the like.

Reference numeral 8 denotes a cooling fan for cooling the electric components in the heating coil 2 and the control circuit 4. The cooling air is sent from the outside through a filter 9 on the lower side of the front of the fuselage and sent out by a cooling fan 8, and one part of the air passes through a duct 10 covering the control circuit 4 to cool electrical components of the control circuit 4. . The cooling air is exhausted from a lower exhaust port 11 provided on a vertical wall on the back of the body, and a waterproof cover 12 is provided at this portion. The waterproof cover 12 largely covers the lower exhaust port 11 to prevent water splashing or intrusion from the outside from entering the inside.

The waterproof cover 12 is a cover having a U-shaped cross section as shown in FIG.
1, the cooling air discharged from the lower exhaust port 11 on the rear surface is divided in the left-right direction and the end 1 of the waterproof cover 12 is divided.
3 is discharged from the exhaust port 14. The purpose of the waterproof cover 12 is to prevent water splashing around the fuselage and water dripping from the exhaust slit 15 of the tenvan 3 'of the fuselage from entering the fuselage and damaging electrical components such as the control circuit 4. The lower exhaust port 11 on the back is largely covered.

On the other hand, the cooling air to the heating coil 2 is exhausted from the upper exhaust port 16 on the rear surface. The upper exhaust port 16 is covered with a large eave-shaped waterproof plate 17 from above. Water entering the airframe is prevented by the waterproof plate 17. The discharged cooling coil cooling air is supplied to the waterproof plate 17.
Exhausted through the underside of

When there is no obstacle around the body, the cooling air discharged from the upper exhaust port 16 and the lower exhaust port 11 is directly discharged to the outside of the body. If there is an obstacle around the airframe and it cannot be discharged to the outside even if it is discharged from the upper and lower exhaust ports 16 and 11, the air is exhausted upward from the exhaust slit 15 behind the tenvan 3 '.

Next, the operation of this embodiment having the above configuration will be described.

Water, oil and the like spilled on the ten ban 3 'during cooking drip into the airframe through the exhaust slit 15 of the ten ban 3', but the upper exhaust port 16 is covered with a waterproof plate 17, The exhaust port 11 is covered with the waterproof cover 12, so that water or oil dripping does not enter the inside of the machine.

Further, even if the water that has fallen on the floor surface jumps, the lower exhaust port 11 is not covered by the waterproof cover 12 because it is largely covered. Since the upper exhaust port 16 is high in position, the one that jumps up to this point does not come. Even if it jumps up, it is shut off by the waterproof cover 12 and no water droplets reach the upper exhaust port 16.

As shown in FIG. 3, the installation location of the airframe may be a sink on the back side. In this case, water may drop onto the airframe when an object is taken in and out of the sink. In the conventional type having no waterproof cover, water dripped from the exhaust slit 15 of the tenban 3 'entered the exhaust port and adhered to the kiban of the control unit 4 to damage the airframe. Can be completely eliminated.

[0023]

According to the present invention, a waterproof plate and a waterproof cover are provided at a portion serving as an exhaust outlet for cooling the electrical components of the object to be cooled, and the exhaust passage is swung in the lateral direction to prevent water entering from the outside. The structure is such that oil etc. does not reach the electrical components, and troubles caused by water or oil intrusion are eliminated.

In order to provide a device that can be used without any practical problems even under severe use conditions, the cross-sectional area of the exhaust passage formed and covered with the waterproof cover is made larger than the opening area of the lower rear exhaust port. The ventilation resistance is kept at the same level as that of the conventional product without increasing, and the structure is such that the built-in electric parts are not damaged by the intrusion of water from the exhaust port.

Further, the exhaust pipe is not connected to the rear part of the machine body, and there is no trouble such as hitting a large heated body (pan) when the large body to be heated is placed. Further, when a plurality of devices are used side by side, there is no problem even if the rear portions are used in a face-to-face manner. Furthermore, it is installed near a sink that uses a large amount of water, and can be used without any practical problem even if there is splash of water from the sink.
