Reference numeral 7 denotes a blowing unit, which is driven by a motor 8 via a shaft. Reference numeral 9 denotes oil smoke removing means provided between the suction unit 6 and the blowing means 7. Numeral 10 forms an air flow path that connects the blowing section 5 and the suction section 6 below the heating means via the blowing means 7 and the oil and smoke removing means 9. With the above configuration, the plate 1 is heated by the heating means 2,
Place ingredients such as meat and vegetables on plate 1 and bake. In general, since cooking is performed after applying oil to the surface of the plate 1, not only oil and water coming out of the ingredients, but also smoke accompanied by oil is generated, and the smoke is diffused into the room by the rising airflow or heated. Oil droplets scatter around. At this time, motor 8
When power is supplied to the air, wind is generated from the blowing means 7 through the shaft, and the air is blown straight from the blowing section 5 to the suction section 6 through the air flow path 10. The blown air pushes oil smoke generated on the plate 1 toward the suction section, is sucked together with the oil smoke from the suction section 6, and the sucked oil smoke is removed by the oil smoke removing means 9. The flow of the air excluding the oil smoke is circulated again to the blowing means 7 through the air flow path 10.

[0003]

However, in the cooking device of the above-mentioned conventional construction, the oil droplets that could not be completely sucked in due to the wind from the blowout portion scattered over the suction portion to the surroundings and were heated. Oil droplets may adhere to hands and face. In particular, scattering of oil droplets in a certain direction becomes noticeable. Further, when a large amount of food such as meat and vegetables is placed on a plate and baked at one time, a large amount of oily smoke is generated, and there are cases where it is not possible to completely suck in the suction part. Furthermore, oil smoke diffused by the upward airflow generated by heating the plate cannot be suppressed only by the wind blown out from the blowout portion and the wind sucked in from the suction portion.

[0004] The present invention is intended to solve the problems of the conventional structure, and not only greatly reduces the diffusion of oil smoke into a room, but also has good usability and cleanability.

(Embodiment 1) A first embodiment of the present invention will be described below with reference to FIG. In FIG. 1, reference numeral 11 denotes a heating coil which generates a high-frequency magnetic field as electric heating means, and 12 denotes a heating coil.
1 is a plate which is a heating appliance for cooking combined with 1 and a thermistor 1 which is a temperature detecting means is provided below the plate 12.
And a drive circuit 14 for controlling the energization of the heating coil 11 by the output of the thermistor 13. Reference numeral 15 denotes a blowing portion provided around the plate 11;
Is a suction unit provided on the side facing the blowing unit 15. Numeral 17 denotes a blowing means for flowing air from the blowing section 15 toward the suction section 16, which is constituted by a radial, sirocco or swept-back centrifugal fan, and is driven by a motor 18 via a shaft. Reference numeral 19 denotes a soot and smoke removing means which is provided between the suction section 16 and the blowing means 17 and removes the sucked soot and smoke. Reference numeral 20 denotes an air flow path that connects the blowing section 15 and the suction section 16 below the heating means via the blowing means 17 and the oil and smoke removing means 19, and is formed by the lower partition plate 21, the main body outer case 22, and the upper partition plate 23. I have. Reference numeral 24 denotes a second blowing section, which is located behind the suction section 16. Reference numeral 25 denotes a blowing passage, which is formed by the lower partition plate 21 and the outer casing 22 of the main body, and is a passage for guiding the wind generated by the blowing means 17 to the second blowing portion 24.

The operation of the heating cooker constructed as described above will be described. When the heating coil 11 is energized, the plate 12 is heated by the magnetic field. As a result, the oil coming out of the food placed on the plate 12 and the oil applied to the plate 12 before cooking are heated to generate oil smoke. At this time, when the motor 18 is energized, wind is generated from the blower 17 via the shaft. Since the blowing means 17 is composed of a centrifugal fan, the generated wind turns in the circumferential direction of the centrifugal fan, passes through the air flow path 20, and flows straight from the blowing section 15 toward the suction section 16 on the plate 12. Air is blown out. This air flow is applied to the plate 12
The oil smoke generated above is flushed toward the suction section 16 and is sucked from the suction section 16 together with the oil smoke. Also,
The oil smoke that cannot be completely sucked by the suction unit 16 and partly diverges to the upper side of the suction unit is blown by the blowing unit 17 and the blowout channel 25.
Through, the smoke and the oil droplets heated by the air blown upward from the second blowing unit 24 are cooled,
It is diffused upward. The sucked oil smoke is the oil smoke removal means 1
9 and the flow of air except oil fumes is
After that, the air circulates again to the blowing means 17.

If there is no second blowout section behind the suction section located on the side opposite to the blowout section, oil smoke or heated oil droplets will flow from the blowout section on the rising airflow generated by the heating of the device to be heated. Most of the air is sucked by the discharged wind and is sucked at the suction part on the opposite side, but part of it cannot be fully sucked and passes over the suction part, causing concentration of oil smoke scattering in a specific direction . However, if there is a blown wind from the second blowout part behind the suction part located on the side opposite to the blowout part, the oily smoke can be diffused above the plate and the concentration of the oily smoke in a specific direction can be eliminated. In addition, there is also an effect of cooling heated oil droplets scattered in a specific direction during cooking and forming a wall of air to prevent the oil droplets from scattering. Further, the position of the second blowing section is not limited to the above embodiment, and is located behind the suction section, and is inclined toward the blowing section from a position perpendicular to the cooking surface. It doesn't matter. By inclining this, a negative pressure is generated between the suction portion and the air from the second blowout portion, which tends to diffuse above the plate, is drawn into the suction portion, and at the same time, the air is drawn over the suction portion. There is also an effect of sucking in oily smoke that is about to scatter.

The heating cooker according to this embodiment has excellent effects in terms of cleanability, safety, and usability.

As described above, according to the present invention, the oil smoke generated by the air from the blow-out section is flushed to the suction section on the opposite side and sucked without diffusing the oil smoke, and the oil smoke is removed by the oil smoke removing means. Needless to say, the configuration is such that the blowout air is discharged from the second blowout portion located behind the suction portion on the side opposite to the blowout portion, so that the oil smoke in the specific direction exceeds the upper portion of the suction portion. Since the concentration of splashes can be prevented, there is no bother due to oil smoke during cooking. In addition, since oil droplets heated during cooking can be prevented from splashing over the suction portion and forming an air wall, safety and cleanability after use can be improved, and the ease of use can be improved. A good cooking appliance for general household can be realized.

Since the blowing means 37 is composed of a centrifugal fan, the generated wind turns in the circumferential direction of the centrifugal fan, passes through the air flow path 40, and flows straight from the blowing section 35 toward the suction section 36 on the plate 32. Air is blown out. This air flow is applied to the plate 32
The oil smoke generated above is swept toward the suction section 36 and is sucked from the suction section 36 together with the oil smoke. Also,
The oil smoke that flows upward without being completely sucked by the suction part is sucked from the second suction part 44 provided on the upper part of the suction part 36. The oil smoke sucked from here is removed by the oil smoke removing means 41 together with the oil smoke sucked from the suction part 36, and the flow of the air excluding the oil smoke is circulated again to the blowing means 39 through the air flow path 42. .

Unlike the suction section perpendicular to the cooking surface of the utensil on the side facing the blowout section, if there is no second suction section parallel to the cooking surface of the utensil to be heated, Oil smoke and heated oil droplets are swept away by the wind discharged from the blowout part on the rising airflow generated by the heating of the equipment, and most are sucked by the suction part on the opposite side, but part is sucked Without going over the suction section
The concentration of oil smoke scattering in a specific direction occurs. However, if there is a second suction portion parallel to the cooking surface of the heated appliance, unlike the suction portion that is located on the side facing the blowout portion and is perpendicular to the cooking surface of the heated appliance, Suction and heated oil droplets that attempt to fly beyond the suction area and fly to the surroundings in a specific direction without diffusing, without being able to fully suck in the suction part in the vertical direction to the cooking surface,
Oil smoke is removed by the oil smoke removing means.

The heating cooker according to this embodiment has excellent effects in terms of cleanability, safety, and usability.

As described above, according to the present invention, the oil smoke generated by the air from the blow-out portion is flushed to the suction portion perpendicular to the cooking surface of the appliance to be heated on the opposite side, and the oil smoke is not diffused. Suction and oil smoke are removed by the oil smoke removing means, and of course, by providing a second suction portion parallel to the cooking surface of the heated appliance, the device is in a direction perpendicular to the cooking surface. As it is possible to prevent the concentration of oil smoke and heated oil droplets scattering in a specific direction beyond the suction part without being able to suck at the suction part,
It is possible to realize a heating cooker for general households that has good safety and cleanability after use, and is easy to use.

(Embodiment 3) A third embodiment of the present invention will be described below with reference to FIGS.

58 is a motor, 59 is oil and smoke removing means, 60 is an air flow path, 61 is a lower partition plate, 62 is an outer casing of the main body, and 63 is an upper partition plate. The above is the same as the configuration in FIG. Reference numeral 64 denotes an oil / smoke blocking wall located above the suction section 56, and has a rotation mechanism section 65. Suction unit 56
The oil and smoke removing means 59 is provided in the suction tower B.

The basic operation of the heating cooker constructed as described above is the same as that of the second embodiment, so that the description thereof will be omitted, and the operation of the oil smoke blocking wall 64 and the related operation will be described.

The flow of the air blown out from the blow-out portion 55 sucks the oil smoke generated on the plate 52 into the suction portion 5.
6 and is sucked from the suction part 56 together with the oily smoke. In addition, the oil smoke that cannot be completely sucked by the suction portion and flows upward to the suction portion is blocked by the oil smoke blocking wall 64 provided on the upper portion of the suction portion 56. The sucked oil smoke is removed by the oil smoke removing means 41, and the flow of the air excluding the oil smoke passes through the air flow path 42 again to the blowing means 3.
It circulates to 9. Further, after the above operation is completed, as shown in FIG. 3B, it is configured to rotate clockwise around the rotation mechanism 65 and to be integrally housed as a part of the suction part 56.

If there is no oil-smoke blocking wall located above the suction portion and perpendicular to the cooking surface of the heated appliance having the rotation mechanism, the heated appliance rides on the rising airflow generated by heating and causes the oil smoke or the like. The heated oil droplets are swept away by the wind discharged from the blow-out part, and most of them are sucked in the suction part on the opposite side, but some of them cannot be completely sucked and pass over the suction part and move in a specific direction. Concentration of oil smoke scattering occurs. However, if there is an oil-smoke blocking wall located above the suction unit on the side opposite to the blowout unit and perpendicular to the cooking surface of the utensil having the rotation mechanism, the suction unit will not be able to fully suck the suction unit. Oil fumes and heated oil droplets that attempt to fly over the surroundings in a specific direction beyond the upper part can be blocked without diffusing. In addition, since it can be stored integrally with the suction section after use, it is not obstructive and has good storage properties.

The heating cooker according to the present embodiment has excellent effects in terms of cleanability, safety and storability.

As described above, according to the present invention, the oil smoke generated by the air from the blowout portion is flushed to the suction portion perpendicular to the cooking surface of the appliance to be heated on the opposite side, and the oil smoke is not diffused. A configuration in which oil smoke is removed by suction and oil smoke removing means, and an oil smoke blocking wall is provided in a direction perpendicular to a cooking surface of a heated appliance having a rotating mechanism, which is located above the suction unit. By doing so, it is not possible to suck in the suction part in the direction perpendicular to the cooking surface, and it is possible to prevent the concentration of oil smoke and the scattering of heated oil droplets in a specific direction beyond the suction part, and after use. Since the configuration is such that it can be stored integrally with the suction section, it is possible to realize a heating cooker for general households that has good safety and cleanability after use, and has good storage properties.

The present invention is not limited to the above-described embodiment, and may be configured such that the oil / smoke barrier can be removed. Further, the oil smoke blocking wall is configured to be perpendicular to the cooking surface, but is not limited thereto. Further, in the present embodiment, the induction heating cooker is taken as an example, but the same effect can be obtained in a heating cooker using a sheathed heater as a heating means. Furthermore, it goes without saying that many modifications and changes can be made to the above embodiment within the scope of the present invention.
