Description

  The present invention relates to an upper heat source lifting device for a roaster.

  Generally, the mechanism by which heat is transferred is broadly divided into conduction, convection, and radiation. In addition, conduction heat is mainly transmitted by solids, and convection heat is mainly transmitted by fluids. In the radiant heat, energy is released as an electromagnetic wave from the surface of a certain heating element, and heat is transferred by this process. Radiant heat is emitted at the speed of light even when there is no medium, and is directly transmitted to the irradiated object. The wavelength range of such radiant heat ranges from, for example, infrared rays to ultraviolet rays having the shortest wavelength in the visible light region. In particular, it is known that infrared wavelength region bands such as far infrared rays, near infrared rays, and near infrared rays have the strongest heat transfer action compared to visible rays and ultraviolet rays.

  Here, the heat source body of the existing roaster is located in the lower part of the roaster. In addition, in order to increase the heat transfer efficiency of the roaster, if the heat source is installed near the baking plate or the heat source is installed inside the equipment, high temperature heat is directly applied to the baking plate during heating, so the baking plate It doesn't get cold and heat is continuously added to the food. Thereby, food was burnt or the taste was affected by excessively heating the grilled plate.

  In addition, if charcoal (charcoal) is the heat source, the level of heat is directly related to the quantity of charcoal and the duration of heating, so cooking workers constantly turn over the food they are cooking, You have to do something like stirring. Such work is very cumbersome and requires considerable experience with such cooking methods.

  In addition, most existing roasters employ a method in which a majority (grilled net) connected to the upper portion of the lower body is connected and fixed.

In electric roasters, due to the delay in adjusting the amount of heat of the heat source body, the heat that remains in the heat source will continue to act on the food even if the power is turned off after the food has been burned. . Moreover, since the heat source body is installed in the lower part, the heat released from the heat source body acts on the food through the grill. Therefore, the user cannot accurately grasp the state of the food, and the food is burnt or the taste is affected by overheating.

At the opening end of the socket 2, a limiting flange 14 that matches the contour of the outer wall of the lifting platform 3 is installed. On the inner wall of the socket 2, a space separation strip 15 attached to the contours of some clamp parts 5 is installed, and the socket 2 is connected to two seating parts 13.

  This structure is convenient for assembling the clamp portion 5 in the socket 2 and can prevent the restriction rod 14 from being separated from the socket 2 as much as possible. The space separation strip 15 serves to limit the movement of the clamp part 5. Thereby, since the said clamp part 5 will move only by the track | orbit of the longitudinal direction designed beforehand, when using a heat source body (400 of FIG. 8), the danger and accident by shaking etc. can be prevented. .

  Although not related to the lifting action of the lifting device 1 of the present invention, the upper end of the lifting platform 3 may be connected to the rotating shaft 16, and the rotating shaft 16 may be connected to a rack bar 17. Thereby, the heat source body can freely move in the horizontal direction at the same height via the rack bar 17 and the rotating shaft 16.
