A control board 115 for forming an electric circuit is disposed inside the cooking device main body accommodating the cooking device 7, and a high-frequency current is supplied to the first induction coil 105 and the second induction coil 106 so that the pan 107 is heated.
Is heated by induction heating to cook the object stored in the pot 107.

A control component for generating a high-frequency current is arranged on the control board 115, and a cooling fan (not shown) for cooling heat generated during high-frequency driving.
Thus, outside air introduced from an intake port (not shown) is applied to a heat-generating component to cool the air, and is discharged from an exhaust port (not shown).

[0006] These intake and exhaust ports are arranged on the bottom and side of the lower part of the cooker main body, but the total area of the holes necessary for introducing and discharging the outside air affects the cooling capacity, so that electric appliances are used. A large number of holes were made as large as possible, assuming that test fingers specified in the standards of the Control Law would not enter.

[0007]

In the above-mentioned conventional cooking device, the test finger cannot be inserted into the cooking device main body, so that the minimum safety is ensured. Since the main use environment is the kitchen, small animals such as cockroaches enter the main body, and oil smoke, dust, etc. are engulfed with air, reducing the cooling capacity and destroying parts of the control board. There is a problem that the function is stopped.

The present invention solves the above-mentioned conventional problems. Small kitchen animals such as cockroaches can be introduced from the intake and exhaust ports to the inside of the cooker body without greatly reducing the efficiency of intake and exhaust to and from the cooker body. An object of the present invention is to prevent intrusion and reduce oil smoke and dust at the same time, thereby stabilizing the cooling capacity of equipment and improving reliability.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a cooking device according to the present invention comprises a pot stored in a cooking device body, an induction coil for heating the pan, and a high-frequency current supplied to the induction coil. a high frequency driving substrate for, and a cooling fan for cooling the high-frequency driving board, the bottom of the cooker body, to discharge an intake port for supplying outside air to the cooling fan, the gas having cooled the high frequency driving substrate With an exhaust port,
Wearing cover of the Utotomoni the porous bottom of the cooker cover of a porous integral structure both of the inlet and exhaust ports
It is provided detachably .

In addition, a space formed by a detachable cover that integrally covers both the intake port and the exhaust port at the lower portion of the main body of the cooker may be divided into an intake chamber and an exhaust chamber by a partition wall. You can do it.

[0011]

In the cooker constructed as described above, a high-frequency current is supplied to the induction coil by the high-frequency drive board, thereby inducing heating of the pot. Cooling fan introduces outside air into the cooker body from the air inlet that introduces outside air to cool it, hits the heat-generating components of the high-frequency drive board and cools them, and the cooled outside air flows out of the cooker body through the exhaust port. Will be released.

Each of the intake port and the exhaust port provided at the lower portion of the cooker main body has a maximum size assuming that a test finger specified in the Electrical Appliance and Material Control Law cannot be inserted, thereby enhancing the intake and exhaust efficiency. .

[0013] Further, by providing a removable porous cover integrally provided at the lower portion of the main body of the cooker and covering the whole of the intake port and the exhaust port, it is possible to easily attach and detach the kitchen, which is a use environment of the cooker. It is possible to prevent the invasion of small animals such as cockroaches and to reduce the invasion of oily smoke and dust by setting the fineness of the porous eyes, and it is easy to clean .

Further , both the intake port and the exhaust port are integrated.
By covering with a porous cover, the space formed between the lower part of the cooker main body can be divided into an intake chamber and an exhaust chamber, so that the outside air introduced from the porous hole of the cover can be removed from the cooker. Heated air that is directly introduced into the intake port provided in the main body and discharged from the exhaust port is also directly discharged to the outside air. The high frequency drive board can always be cooled by the outside air without being mixed in the space formed between the cover and the lower portion of the cooker main body.

[0015]

An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a longitudinal sectional view showing a rice cooker according to an embodiment of the cooker of the present invention. In FIG. 1, a protection frame which is a storage portion of a pot 2 is provided inside a substantially cylindrical cooker body 1. The bottom 3 and the protective frame side 4 are provided. The protective frame bottom 3 is made of a non-metallic material, for example, thermoplastics, and the pot 2 is made of, for example, a clad steel plate having an outer surface made of a magnetic material, and the pot flange 2a is in contact with the upper frame 5. Supported by Reference numeral 6 denotes an induction coil that generates a high-frequency magnetic field by a high-frequency current generated by the high-frequency driving board 7 and causes the pan 2 to generate heat.

A resin lid 8 is supported on the upper frame 5 of the cooker main body 1 via a pin 9 by a hinge portion 5a integrally formed with the upper frame 5 so as to be openable and closable.

A handle 8a is provided on the upper surface of the lid 8, an engaging lever 10 is disposed on the opposite side of the hinge 5a, and a hook 5b with which the engaging lever 10 is engaged is integrally formed on the upper frame 5. The lid 8 is closed.

Reference numeral 11 denotes a body which constitutes the side surface of the cooking device main body 1, and has a heat insulating effect by forming the cooking device main body side surface portion into a double structure.

Reference numeral 12 denotes a lower frame which constitutes the bottom of the cooking device main body 1. The lower frame is provided with an intake port 12a on the bottom and an exhaust port 12b on the side, and a cooling fan 13 is disposed above the intake port 12a to absorb outside air. Exhaust is forced.

Reference numeral 14 denotes an integral cover which is provided so as to cover the entire bottom and side surfaces of the lower frame 12, and is made of a porous material.
For example, a punched metal having a hole having a diameter of 3 mm or less is formed, and the whole of the intake port 12a and the exhaust port 12b which are detachably attached to the lower frame 12 and provided in the lower frame 12 are formed.
Therefore , it covers both the intake port 12a and the exhaust port 12b . Further, a partition wall 12c for distinguishing a space formed between the lower frame 12 into an intake-port-side space and an exhaust-port-side space is provided so that there is no direct air flow between the intake-port-side space 12d and the exhaust-port-side space 12e. ing.

The cover 14 is a punched medal through which air can flow, but it may be formed partially or entirely by using a fine-grained hole shape such as glass fiber. Then, it is possible to prevent small animals in the kitchen, such as cockroaches, from entering the inside of the cooker main body 1, and to change the porous material depending on the size of oil smoke, dust, and the like.

[0022]

As is apparent from the above description of the embodiment, according to the present invention, the cooling performance of the heat-generating components of the high-frequency board housed in the main body is ensured, and the cockroach and the like in a kitchen environment using a cooker are secured. The intake port should be designed to prevent the entry of small animals and reduce ingress of oil smoke, dust, etc. inside the main body.
The exhaust port is detachably installed with an integral porous cover.
With this simple configuration , destruction of components and a decrease in cooling efficiency can be prevented, and cleaning is easy and safety and durability are improved.
