Description

  The present invention relates to an infrared heating cooker.

  In general, infrared rays cannot be seen with the naked eye, are not scattered much in the air, and have a transmission power stronger than visible light. Infrared rays are physically divided into near infrared rays (about 0.8 μm to about 2.0 μm), middle infrared rays (about 2.0 μm to about 4.0 μm) and far infrared rays (about 4.0 μm to about 2.0 μm) in order of wavelength. 1000 um).

  Here, infrared rays have a thermal effect that penetrates deeply into cooking ingredients when cooking ingredients are heated, and have a strong thermal action characteristic on cooking ingredients as compared to visible light and ultraviolet rays, so they are used for heating and cooking utensils. ing.

  However, the cooking utensils as described above are provided with one or more cooking plates for cooking on the cooking plate and changing the irradiation direction of infrared rays while fixing the irradiation direction of infrared rays or along the same horizontal plane. However, it is comprised so that the cooking which grills meat or fish etc. with the same cooking plate may be performed.

  For example, Patent Literature 1 and Patent Literature 2 disclose cooking utensils that cook on a cooking plate while fixing the direction of infrared irradiation. Patent Document 3 discloses a cooking utensil for cooking on a cooking plate while changing the irradiation direction of infrared rays along the same horizontal plane.

  Next, the utilization method of the infrared heating cooking appliance 100 which concerns on this invention is demonstrated with reference to FIGS.

  1 to 4, first, an infrared heating cooker 100 is prepared. The infrared heating cooker 100 may include a first cooking plate 106 and a second cooking plate 112 between the lower main body 111 and the upper main body 110. Here, the lower main body 111 and the upper main body 110 can be connected to the fixing member 108. The upper body 110 includes a heating element 120 that is electrically connected to the fixing member 108. Subsequently, one or more cooking ingredients are prepared on the first cooking plate 106 and the second cooking plate 112.

  An external power supply is supplied to the fixing member 108. The fixing member 108 can apply an external power source to the heating element 120 of the upper body 110. The heating element 120 can irradiate the first cooking plate 106 and the second cooking plate 112 with infrared rays. The first cooking plate 106 and the second cooking plate 112 are irradiated with infrared rays from the heating element 120, but the first cooking plate 106 and the second cooking plate 112 are different in the degree of being heated by infrared rays. Therefore, they may be considered separately from each other in terms of heat flow.

  In other words, the first cooking plate 106 receives infrared irradiation on the peripheral area of the first cooking plate 106 and supplies conduction heat from the second cooking plate 112 toward the peripheral edge of the first cooking plate 106. During the heating of the central region of the first cooking plate 106, the central region surrounded by the peripheral region of the first cooking plate 106 is sequentially heated while the peripheral region of the first cooking plate 106 is heated. The second cooking plate 112 is heated again by radiating radiant heat from the central region of the first cooking plate 106 toward the second cooking plate 112.

  Here, when the heating element 120 of the upper body 110 is surrounded by the bellows tube 140 shown in FIG. 3, the bellows tube 140 reduces the infrared irradiation range by the heating element 120 due to the self-characteristics related to the shape deformation. Can be concentrated on the first cooking plate 112 or the second cooking plate 112. Further, when the upper main body 110 rotates with respect to the driving unit 108b of the fixing member 108 as shown in FIG. 4, the heating element 120 of the upper main body 110 concentrates the infrared irradiation range on the second cooking plate 112. Or can be concentrated on the first cooking plate 106 and the second cooking plate 112.

  The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to such examples. It is obvious that a person having ordinary knowledge in the technical field to which the present invention pertains can come up with various changes or modifications within the scope of the technical idea described in the claims. Of course, it is understood that these also belong to the technical scope of the present invention.
