On the other hand, there is an electromagnetic induction heating cooker that is likely to spread to ordinary households in the future, and it is currently planned that the standard equipment will be planned as a kitchen facility for new apartments. As a reason for the widespread use of such electromagnetic induction heating cooking utensils, it is usual to draw 200V as a household commercial power supply, and against the background of deregulation such as the allowable current capacity of the house wiring is 15A, Although the power consumption is relatively large, an electromagnetic induction cooking utensil that is safe and can easily obtain high thermal efficiency without handling an open flame can be easily entered into the home.

However, in the above-mentioned configuration of the conventional proposal for the purpose of improving the exhaust function of the ventilator, since it is premised on the use of a heating cooker that uses city gas, propane gas, or the like as a heat source, the above-described electromagnetic induction cooker is used. It has been found that the effect of the discharge function is difficult to obtain during cooking.

That is, during cooking using gas as a heat source, a large convection of air heated by the powerful heating power of the combustion gas is generated at the cooking position, and hot air, combustion smoke, and odor are generated through the convection air. Although cooking by an electromagnetic induction cooker is to be induced upward, the object of operation is to place a heated object such as a metal pan or pan in the magnetic flux generated by the high-frequency alternating current. Because it is based on the heating principle that it is heated in a non-contact manner by receiving induction heating caused by the induction action, air convection is unlikely to occur at the cooking position, and the hot air, combustion smoke, and odor using this are raised In the conventional configuration, the hot air, combustion smoke, and odor generated by the use of electromagnetic induction cooking utensils are efficiently guided to the ventilator exhaust position. Rukoto can not, were those that leave room for improvement in that.

  The present invention was devised in the course of research and development for pursuing the performance improvement of conventional ventilators and devices that assist the exhaust function of ventilators in view of the above circumstances, and its purpose is In addition, even when cooking with an electromagnetic induction cooker, the generated hot air, combustion smoke, and odor can be efficiently guided to the discharge position of the ventilator, and the advantages and functional characteristics of the electromagnetic induction cooker can be fully exploited. An object of the present invention is to provide a ventilation assist device in an electromagnetic induction cooking appliance.

In order to solve the problem, the first technical means adopted by the present invention is to dispose a plurality of blowing holes directed obliquely upward in the outer peripheral area of the electromagnetic induction cooking appliance in the same direction along the outer circumference of the cooking appliance. The air blown from each of the blowout holes is configured to generate an upward spiral air flow centered on the cooking position of the electromagnetic induction cooking utensil, and each of the blowout holes has a blowing direction of the blown air. It is configured to be variable in the vertical and horizontal directions .

Therefore, according to the present invention, hot air, combustion smoke, odor, and the like generated during cooking are quickly guided and guided upward along with the upward spiral airflow centered on the cooking position, and collected in the ventilation device. Since it is discharged to the outside afterwards, it does not stay or fill up near the cooking position of the kitchen and can maintain a comfortable kitchen usage environment.

In addition, since the blowing air from each blowing hole constituting the ventilation assist device can change the blowing direction up and down and left and right, the difference in the size of the cooking device such as a pan, frying pan, etc. used for cooking, The optimum upward spiral airflow can be arbitrarily adjusted according to the cooking contents such as “simmering”, “sautéing”, “baking”, etc., and various usage forms can be made possible.

The best mode for carrying out the present invention will be described in detail with reference to the accompanying drawings.
In FIG. 1, reference numeral 1 denotes a ventilation assistance device according to the present invention. The ventilation assistance device 1 is obliquely disposed on an outer peripheral region of an electromagnetic induction cooking appliance 4 placed and fixed on the upper surface of a cooking table 3 constituting a kitchen 2. A ventilation assisting device 1 is configured by arranging a plurality of air blowing portions 6, 6, in which the blowing holes 5 directed upward are directed in the same direction along the outer periphery of the cooking utensil 4.

A smoke hood 7 is disposed on the ceiling 2 a located above the electromagnetic induction cooking utensil 4, and a cooking utensil 8 such as a pan is placed on the cooking surface 4 a of the electromagnetic induction cooking utensil 4. When cooking is performed, hot air, combustion smoke, and odor generated along with the cooking are discharged to the outside through an exhaust duct and a ventilation fan (not shown) connected to the smoke hood 7.

As shown in FIG. 2 and FIG. 3, the air ejection parts 6, 6... Stand up from the air supply pipe 9 having a quadrilateral frame shape disposed below the cooking table 3. A connecting pipe 11 having an opening surface 11a is connected to the upper end portion of the branch pipe 10 so as to be horizontally rotatable, and a blowout hole is formed in the opening end portion 12a of the rotating pipe 12 pivotally supported on the proximal end side of the connecting pipe 11. 5 is formed, and the air jetting part 6 is configured so that the blowout direction X of the blown air from the blowout hole 5 can be varied up and down and left and right.
