Description

  The present invention relates to a cooking device.

  Generally, the mechanism by which heat is transferred is broadly divided into conduction, convection, and radiation. However, conduction heat is mainly transmitted by solids, and convection heat is mainly by fluid. Communicated.

  Radiant heat is transferred in the process in which energy in the form of electromagnetic waves is released from the surface of an arbitrary heating element, and heat is emitted at the speed of light even in the absence of a medium. Directly transmitted. The wavelength range of such radiant heat reaches from the infrared ray through the visible ray region to the ultraviolet ray region with the shortest wavelength. However, it is known that infrared wavelength regions such as far infrared rays, near infrared rays, and mid infrared rays have the strongest thermal action compared to visible rays and ultraviolet rays.

  Thus, various cooking utensils using infrared rays have been developed in the past. For example, in Japanese Invention Registration No. 10-79225, an infrared lamp whose exterior is composed of a quartz tube, a cooking container installed above the infrared lamp, and a reflector installed under the infrared lamp Infrared meat grill made of

  Such an infrared meat grill is a one-way heating method in which an infrared lamp heats a cooking container, and this cooking container burns only the lower part of the meat, and there is inconvenience that must be repeated repeatedly so that the meat does not burn. Yes, thermal efficiency is also reduced.

  In addition, Japanese Utility Model Registration No. 20-314608 introduces a meat griller with a near-infrared lamp installed at an appropriate distance above the grill, and a reflector installed above the lamp. . These meat grillers have the advantage that the meat placed on the grill is directly irradiated with near infrared rays to bake the meat, so that the meat can be evenly baked.

  However, the meat grill also has the inconvenience that the meat must be kept repeated as a one-way heating method in which the near infrared rays emitted from the lamp burn only the upper part of the meat. Moreover, in the case of a cooking container using these infrared rays, there is a problem that the time for baking the food placed on the cooking container is delayed, and in order to heat the food placed on the cooking container, an infrared lamp is used for a long time. Since the light must be turned on, there is a problem that a cost burden due to an increase in the electricity bill is further generated.

  On the other hand, the present applicant has devised a bidirectional cooking device of Patent Application No. 10-2009-0006812 to solve the problems of the conventional cooking device, which forms a substructure. A pedestal, a support base installed vertically in the center of the upper surface of the pedestal, and a cooking container which is detachably installed in the upper part of the pedestal and has a central hole through which the support base passes. A cover installed on the upper stage of the support, an upper heating element that is provided at the lower part of the cover and emits radiant heat (R) toward the cooking container, and a cooking container configured on the bottom surface of the cooking container A lower heating unit that directly transfers heat to the cooking container, and the cooking container is heated by radiation heat from the upper heating element and direct heating of the lower heating element, and food is heated by the upper heating element. Body radiant heat and lower part Top and bottom are configured to burn simultaneously by direct heating of the heat member.

  Therefore, by baking the upper and inner parts of the food with the upper and lower heating elements, the heat efficiency is superior to that of the conventional one-way cooker, and it is particularly scorching even if the food for baking is not repeated repeatedly. Therefore, it is expected to have an effect of producing almost no smoke or odor from the cooking process.

  However, in the case of the bidirectional cooking device of the patent application No. 10-2009-0006812 previously filed by the present applicant, in order to clean the cooking container placed on the upper stage of the lower heating element, it can be removed or cooked. When the container is placed on the upper stage of the lower heating element, the cooking container cannot be placed on the lower heating element unless the upper heating element is removed from the support base connected to the lower heating element. is there.

  In other words, the coupling structure of the cooking container has a fitting structure in which a through hole formed in the center of the inside of the cooking container is inserted and fitted from the upper side of the support base, so that the cooking container is removed from the lower heating element. In addition, the upper heating element must be removed first before joining, so that the usability is lowered and there is an inconvenient problem. Also, despite the structural advantages of using a container on the lower heating element, there are various ways to cook and eat other types of food, such as for pottery, chige and sukiyaki. There is a problem that it is necessary to replace the cooking container, and it is difficult to use the combined container at the same time.

  In order to solve the above problems, the present applicant has filed as application number 10-2009-0043420 (Title of Invention: Improved bidirectional cooking device) dated May 19, 2009, claiming The range of “the upper heating element 11 that is located on the upper side and has a heat radiating part that emits radiant heat therein, the lower heating element 12 that is located on the lower side and has a heating part therein, and In the bidirectional cooking device constituted by the upper heating element 11 and the support base 13 for connecting the lower heating element 12, a coupling jaw 14 is further formed on the upper outer peripheral surface of the lower heating element 12, and the lower A first coupling groove 21 seated on the coupling jaw 14 of the heating element 12 is formed along the lower peripheral portion to form an incision portion 22 incised on one side, and is connected to the incision portion 22 to support the support.
