  FIG. 1 is a perspective view showing the overall configuration of a heat source multiple irradiation type infrared cooker according to the present invention, and FIG. 2 is a cross-sectional view of the main part showing the configuration of a heating head in the heat source multiple irradiation type infrared cooker according to the present invention. FIG. 3 is an enlarged cross-sectional view showing a main part of the configuration of the level adjusting device in the heat source multiple irradiation type infrared cooking device according to the present invention, and FIG. 4 is a diagram showing the heat source multiple irradiation type infrared cooking device according to the present invention. It is an operation example diagram showing a lowered state of the heating head.

An embodiment of the present invention will be described below with reference to the accompanying drawings. As shown in FIG. 1, a heat source multiple irradiation type infrared cooker (A) according to the present invention has a cooking pan 10 on which various food ingredients to be cooked (hereinafter referred to as “cooking ingredients”) are placed at the upper end. The device body 1 to be used, and a doughnut shape so that the cooking material placed on the cooking pan 10 is heated by being irradiated with a high-temperature heat source in a state of being spaced apart from the upper side of the device body 1 And a heating head 2 that can irradiate a wide range of heat sources outside the device, and stands on the device body 1.
The heating head 2 is provided in the up state, and the heating head 2 is mounted on the apparatus main body 1 so that the heating head 2 can be mounted separately. The heating head 2 is integrally connected to the heating head 2 and assembled to the support 3. The level adjustment device 4 is configured to adjust the height of the heating head 2 by moving up and down along the length direction of the column 3 in the state.

  The device main body 1 is a base structure of equipment configuration and equipment operation, and has a built-in related device. The amount of heat source emitted from the heating head 2 when the power supply is turned ON / OFF. It is preferable that a controller (Jog & shuttle) 11 capable of adjusting the temperature stepwise is further provided outside.

  The heating head 2 is a heating device for releasing a high-temperature heat source so that the cooking material placed on the cooking pan 10 is cooked. As shown in FIG. By having a donut shape, the heating element 20 accommodated in the lamp shade 21 also has a ring shape. However, the heating head 2 is not necessarily limited to such a shape, and the mode in which the column 3 penetrates the round disk-shaped heating head 2 according to the coupling method of the heating head 2 and the column 3 is also included in the present invention. It belongs to one embodiment.

Here, the heating element 20 emits infrared rays that are suitable for heat cooking in which cooking ingredients on the cooking pan 10 are boiled and baked, and that has a stronger thermal action than visible light and ultraviolet light. Infrared lamp (infrared
lamp) is preferably used, but the present invention is not necessarily limited thereto, and a far infrared heater, a sheathed heater, a resistance heating wire, or the like may be used as long as it can radiate heat.

  In addition, it is preferable that a metal material (including stainless steel) reflecting plate 211 for radiating heat radiation is provided between the heating element 20 and the lamp shade 21. The reflection plate 211 surrounds the heating element 20 and has an inverted “U” shape and is positioned inside the heating head 2 so that the opening direction of the reflection plate 211 is reflected downward and the radiant heat radiated from the heating element 20 is reflected downward. To do.

  More specifically, the lamp shade 21 is located inside the heating head 2, and the reflector 211 is located inside the lamp shade 21. When the heating element 20 is viewed as a center, the heating element 20 and the lamp shade 21 are located. The reflector 211 is positioned between the two. Of course, the position of the reflecting plate 211 may be changed in various ways, and it is obvious that the position can be changed in various ways according to the shape of the heating head 2 and the shape of the heating element 20.

This is to maximize the radiation effect of heat by sufficiently irradiating the cooking pan 10 with heat radiated from the heating element 20 composed of an infrared lamp, a far-infrared heater, a sheathed heater or a resistance heating wire. As a result, the cooking ingredients are cooked quickly, and at the same time, the heat source enters the cooking ingredients uniformly during cooking, and at the same time deeply penetrates the cooking ingredients (thermal
effect).

  Further, the opening direction of the reflector 211 is formed in an inverted “U” shape so as to face the central portion of the cooking pan 10, and thereby the heat source emitted from the heating element 20 located outside the device, The radiant heat is irradiated evenly on the peripheral area as well as the central area of the cooking pan 10.

  Furthermore, a plurality of supports 22 for connecting the heating head 2 and the level adjusting device 4 together are provided from the inner rim portion of the lamp shade 21. Thereby, the level adjustment device 4 enables the heating head 2 to be spaced apart above the cooking pan 10.

  However, in one embodiment of the present invention, the space between the support column 3 and the heating head 2 is secured by using a plurality of support tools 22, but this is not necessarily limited to such a shape, and the support tool 22 itself The support column 3 and the heating head 2 may be assembled while omitted.

  In such a case, although not shown in the drawing, a predetermined space that can be coupled to the column 3 is provided inside the heating head 2. The support column 3 is a support for maintaining the mounting and separation state of the heating head 2 and forms a certain height from the center upper end of the device body 1 as described above and further illustrated in FIG. Grooves 31 are formed continuously along the length direction in the upper portion so as to move the upper and lower levels of the level adjusting device 4 and to fix the position when the level adjusting device 4 is stopped.

  The level adjusting device 4 is for attaching the heating head 2 to the support column 3 so that the height can be adjusted. As shown in FIG. 3, the level adjusting device 4 is assembled so as to surround the support column 3. A hub ring that is movable along the length of the column 3 is preferred. However, the level adjusting device 4 may be embodied while surrounding a part of the outer diameter without surrounding the entire outer diameter at one point of the support column 3, and in some cases, the level adjusting device 4 may be realized by holding the back surface on both sides. It may be embodied so that it can be assembled and moved in the length direction of the column 3.

  On the inner side that surrounds the column 3, a locking member 41 is formed in which a penetrating part (411) having a sharp shape protrudes so as to be inserted into the groove 31. Here, the locking member 41 is preferably made of a material having elasticity capable of organically responding to an external force transmitted when the penetrating portion 411 is inserted into or removed from the groove 31. Alternatively, an elastic spring material may be used instead.

  On the other hand, FIG. 5 is a main part enlarged sectional view showing another configuration of the level adjusting device 4 in the heat source multiple irradiation type infrared cooker according to the present invention, and the structure of the level adjusting device 4 is different from the above. The height adjustment of the heating head 2 can be made manual or automated (electric) by the user's selection. For this purpose, as shown in FIG. 5, the level adjusting device 4 includes a first gear 42 and a second gear 43 that change a user's manual or automatic rotational motion into a linear motion. And when implemented automatically, the drive motor 44 for giving the rotational force of the 2nd gear 43 is provided.

  At this time, the operation process realized automatically is as follows. A first gear 42 is connected to the outer surface of one side of the support column 3 in the vertical direction, and a second gear (pinion) meshing with the first gear 42 is provided on one side of the level adjusting device 4. ) 43, and the level adjusting device 4 moves up and down by allowing the second gear 43 that is axially coupled to the drive shaft to rotate in the forward or reverse direction by the rotational drive of the drive motor 44. The height of the heating head 2 can be adjusted. Further, an operation lever 45 for adjusting the position of the drive motor 44 is provided so as to be exposed to the outside of the level adjusting device 4, and the operation method such as physical or mechanical pressurization by the user using the operation lever 45 is provided. By moving the position of the drive motor 44 by releasing the gear meshing state between the first gear 42 and the second gear 43, the user can directly manually move the level adjustment device 4 up and down. It becomes like this.

  At this time, an operation method such as physical or mechanical pressurization of the operation lever 45 may be performed not only by the user's operation but also by an electrical switch operation or the like.

  Further, the operating lever 45 is configured so that the meshing state of the first gear 42 and the second gear 43 is maintained again by allowing the drive motor 44 to return to the original position when the external pressure is lost. It is preferable that an elastic spring 46 is further provided.

  An unexplained symbol “40” is a grip portion configured to be grasped by a hand for the vertical movement of the level adjusting device 4. “Θ” is emitted from the heating element 20 and irradiated to the cooking pan 10. This is the irradiation range of the heat source.

  The operation of the heat source multiple irradiation type infrared cooker (A) according to the present invention configured as described above will be specifically described as follows.

  First, in a state where the cooking pan 10 on which cooking ingredients are placed is placed on the device main body 1, the controller 11 of the device main body 1 is operated to start cooking, thereby supplying power and thereby the heating element of the heating head 2. By allowing infrared rays (heat sources) to be emitted from 20, the cooking material placed on the cooking pan 10 is cooked by infrared rays as time passes. Here, as described above, since the heating head 2 has a donut shape, a heat source (infrared ray) is emitted in a state where the heating element 20 is positioned outside the device, and the inside of the lamp shade 21 Further, a heat source emitted by the reflector 211 further provided is applied toward the central portion of the cooking pan 10 placed on the apparatus main body 1.

  As described above, as to the heat source irradiated to the cooking pan 10 as described above, when the heating head 2 is disposed at a position close to the uppermost portion of the support column 3, as shown in FIG. Due to the structural characteristics of the head 2 and the ring-shaped heating element 20 provided on the inside thereof, the irradiation range (θ) of the heat source is distributed over the entire cooking pan 10 and the heat source is balanced over the entire cooking pan 10 region. As a result of the multiple irradiation, the entire cooking material placed on the cooking pan 10 is baked without unevenness, so that the cooking performance is greatly improved.

  As shown in FIG. 4, by reducing the height of the heating head 2, the efficiency of irradiation of the heat source emitted from the heating element 20 can be maximized. This can be achieved by moving the level adjustment device 4 downward and lowering the heating head 2.

  At this time, the penetration portion 411 of the locking member 41 is moved stepwise by the groove 31 formed around the support column 3 in the process in which the level adjusting device 4 moves downward, and any of the positions where the movement is stopped The level adjusting device 4 is fixed by inserting a pointed portion of the penetrating portion 411 into the single groove 31. Thereby, the heating head 2 can also maintain the position.

  Thereby, the heating head 2 and the cooking pan 10 are in a state of being close to each other, and as a result, the cooking ingredients on the cooking pan 10 can be cooked quickly and efficiently. In summary, in the cooking pan rotating infrared cooker (A) capable of adjusting the position and eccentric rotation of the cooking pan according to the present invention, the heat source is emitted in a wide range on the outside of the device, and multiple irradiation is performed with a uniform distribution. As a result, not only the central region of the cooking pan 10 but also the heat source irradiation is balanced not only to the peripheral region, but also the same region is irradiated with the overlapping heat source, resulting in the cooking pan. The effect that the efficient cooking which can bake (or boil) the whole cooking material put on 10 uniformly can be raised.

  In addition, the cooking pan 10 and the heating head 2 are brought close to each other by adjusting the height of the heating head 2 by the vertical movement of the level adjusting device 4, so that the efficiency of transmission of the heat source irradiated from the heating element 20 is improved. The effect which improves greatly can be raised.

  On the other hand, in the embodiment of the present invention, the heating head 2 having a so-called donut shape has been described as a reference. However, the present invention is not necessarily limited to this shape, and a shape such as a quadrangle or an ellipse whose center is open is also applicable. Is possible. Further, a mode in which the central portion of the heating head 2 is not opened and the column 3 is operated through a hole through which the column 3 penetrates can also belong to an embodiment of the present invention.

  In the embodiment of the present invention, the first gear 42 and the second gear 43 have been described as a rack gear and a pinion gear. However, the present invention is not limited to this, and a structure that can move up and down along the column 3. Then, the present invention may be applied by forming a plurality of screw threads on the outer peripheral surface of the support column 3 and the level adjusting device 4 in a male-female structure.

  According to the heat source multiple irradiation type infrared cooker according to the present invention formed as described above, the following various effects are realized.

  First, in the heat source multiple irradiation type infrared cooker according to the present invention, the heating element 20 (lamp) is located at the center of the lamp shade 21 and the heat source emitted therefrom is concentratedly irradiated only on the central portion of the cooking pan 10. Unlike the case where the heating head 2 is provided with a heating element 20 on the inside, the structure of the heating head 2 forms a donut shape, so that the heat source is widely irradiated outside the device, and not only the central region of the cooking pan 10 but also all of them. As a result, it is possible to obtain an effect of greatly improving the efficiency of cooking by baking the cooking material placed on the cooking pan 10.

  Secondly, since the heating head 2 is arranged closer to the cooking pan 10 by adjusting the height of the heating head 2 by moving the level adjustment device 4 up and down, the cooking power is eventually baked by improving the irradiation power of the heat source. The effect of maximizing the cooking performance (or cooking) can be obtained.

  Third, the above-mentioned various effects improve the convenience for users and improve consumer purchasing satisfaction, thereby improving product competitiveness and increasing the profits of manufacturers and distributors. In addition, effects such as greatly contributing to activation can be realized.

  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.
