Description

Electric burner {ELECTRIC STOVE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric burner, and more particularly, to an electric burner used to heat a heated object by radiant heat, for example, to cook fish, meat and other food ingredients.

As the prior art which is the background of the present invention, there is a description of an electric burner that can suppress the generation of smoke and can be miniaturized, and can be used casually for cooking even in a general household. The said electric burner contains two support plates, for example, and is arrange | positioned so that two mirror surface parts may oppose with a predetermined space | interval between two support plates. The two mirror surfaces are each formed of a first partial elliptic pillar surface portion and a second partial elliptic pillar surface portion. Inside two mirror surfaces, heat-transfer elements, such as a sheath heater, are arrange | positioned at the position just under the to-be-heated body. In addition, the focal point of one of the first partial elliptic pillar surface portions and the focal point of one of the second partial elliptic pillar surface portions are arranged on the same axis, and a heat transfer element is disposed near the focal point (see Patent Document 1, for example). .

In the said electric burner, in two mirror surface parts, the heating wire radiated from the heat-transfer element arrange | positioned near one focal point of a 1st partial elliptic pillar face part is reflected by a 1st partial ellipse pillar face part, and is the other side of a 1st partial elliptic pillar face part. After being collected at the focal point of the object, the object to be heated is irradiated. Moreover, a part of the heating wire which is not irradiated to a to-be-heated body is reflected by the 2nd partial elliptic pillar surface part of each mirror surface part, and is reflected by the 1st partial elliptic pillar surface part of the opposing mirror surface part, and is irradiated to a to-be-heated body. That is, in the said electric burner, the 1st partial elliptic pillar surface part has a heating function for heating a to-be-heated body, and the irradiation efficiency which irradiates a to-be-heated body to the heating wire radiated from the heat-transfer element of a 2nd partial elliptic pillar surface part is improved. .

[Patent Document 1] Japanese Unexamined Patent Publication No. 2002-340345 (Page 3 to Page 4, Figs. 1 to 3)

However, in such an electric burner, the mirror surface portion is formed integrally with the first partial elliptic pillar surface portion, and the focus of one of the first partial elliptic pillar surface portions and the focus of one of the second partial elliptic pillar surface portions is reduced. It is arrange | positioned on the same axis, and is arrange | positioned so that the heat-transfer element may be arrange | positioned in the vicinity of the said focal point, and the mirror part and the heat-transfer element are arrange | positioned so that heat efficiency may become as possible, for example, according to the size of a to-be-heated body, one mirror part The degree of freedom in design, such as widening or narrowing the distance between the mirror surface and the other mirror surface part, necessarily becomes small.

Moreover, in such an electric burner, according to the size of a heat-transfer element, such as the case where the diameter of a sheath heater is large, since the heat wire radiate | emitted from a heat-transfer element stays inside the mirror surface part, the heat wire which is not irradiated to a to-be-heated body is removed. There is a case where the first partial elliptic pillar face portion which reflects from the two partial ellipse pillar face portion and opposes is not efficiently irradiated. In this case, the heating wire cannot be adjusted well, and the reflection efficiency of reflecting the heating wire from one mirror surface portion to the other mirror surface portion becomes worse. That is, there is a problem in that the second partial elliptic pillar surface portion cannot fully exhibit the function for improving the efficiency, heat loss occurs, and it is difficult to sufficiently improve the thermal efficiency.

In addition, when cooking fish, meat, and other food ingredients with such an electric burner, residues caused by juice, oil, etc. are mainly adhered to the mirror surface portion, and in particular, the periphery of the first focal point of the elliptic pillar surface portion (heating element). In the periphery of the focal plane) and the other focal point, the temperature is high, so that the residue adhering to the mirror surface part around the focal point is difficult to remove. In addition, in order to clean the debris attached to the mirror surface part, it is necessary to clean it by putting a hand between the two mirror parts or cleaning after separating the mirror part and the heat transfer element from the support plate. If the product is cleaned immediately after use, there is a danger of a burn or the like. Therefore, cleaning is required after a certain time has elapsed. On the other hand, in the latter case, since the work of disassembling the mirror surface part and the heat-transfer element from the support plate every time cleaning is required, it becomes very troublesome.

Therefore, the main object of the present invention is to provide an electric burner in which the degree of freedom in design is increased. Another object of the present invention is to provide an electric burner that can further improve thermal efficiency.

The electric burner 10 of the present embodiment includes two mirror surfaces 12a and 12b. The two mirror surface parts 12a and 12b are formed in the plate body of elliptical arc-shaped cross section which has a longitudinal direction.

Two mirror-surface parts 12a and 12b are arrange | positioned facing in parallel at predetermined intervals so that those opening parts 14a and 14b may face each other, as shown in FIG. Two mirror surface parts 12a and 12b are arrange | positioned at intervals in the direction orthogonal to a horizontal direction orthogonal to the longitudinal direction of the said mirror surface parts 12a and 12b.

Since the two mirror surfaces 12a and 12b have the same structure, only one mirror surface portion 12a is described in detail, and the detailed description of the other mirror surface portion 12b is omitted.

As shown in FIG. 6, the mirror surface portion 12a includes, for example, a partial elliptic mirror surface portion 16a as a partial elliptic mirror surface portion. The partial elliptic pillar face 16a has a focus F1a and a focus F2a. The partial elliptic pillar surface part 16a is comprised by the surface of a part of elliptic pillar surface. In this case, the partial elliptic pillar surface part 16a is comprised by the curved surface a of a part of elliptic pillar surface (alpha), for example as shown in FIG.

In this case, the partial elliptic pillar surface portion 16a has an upper portion 18a and a lower portion 20a that can be separated into two in the vertical direction. That is, the partial elliptic pillar surface portion 16a is composed of a partial elliptic pillar portion of the upper portion 18a and a partial elliptic pillar portion of the lower portion 20a.

The 1st reflective mirror surface part 22a is integrally provided in the lower part 20a of the partial elliptic pillar surface part 16a. The 1st reflective mirror surface part 22a contains the reflecting surface main body 24a, and the reflecting surface main body 24a is formed in the flat plate state, for example. The 1st reflective mirror surface part 22a is arrange | positioned below the sheath heaters 32a and 32b mentioned later.

Similarly, the other mirror surface part 12b includes the partial elliptic columnar surface part 16b which has the upper part 18b and the lower part 20b which can be divided into two in the up-down direction, and the partial elliptic columnar part The 1st reflective mirror surface part 22b is integrally provided in the lower part 20b of 16b. For example, as shown in FIG. 6, the partial elliptic pillar surface portion 16b is composed of a curved surface b of a part of the elliptic pillar surface β with a focus F1b and a focus F2b.

Moreover, the one end side and the other end side of the two mirror surface parts 12a and 12b are connected and hold | maintained by the holding member 26, respectively, as shown to FIG. 1 and FIG. The holding member 26 includes an upper holding plate 28 and a lower holding plate 30. The upper holding plate 28 connects and holds the upper portion 18a of the first mirror surface portion 12a and the upper portion 18b of the second mirror surface portion 12b, and the lower holding plate 30 The lower portion 20a of the first mirror surface portion 12a and the lower portion 20b of the second mirror surface portion 12b are connected and held.

On the other hand, sheath heaters 32a and 32b are disposed inside the two mirror surfaces 12a and 12b as heat transfer elements, respectively. Sheath heater 32a is arrange | positioned inside the mirror surface part 12a near one focal point F1a of the partial elliptic pillar surface part 16a. In addition, the sheath heater 32b is arrange | positioned near one focal point F1b of the partial elliptic pillar surface part 16b inside the mirror surface part 12b. In this electric burner 10, as shown, for example in FIG. 6, sheath heaters 32a and 32b are provided in the place which deviates from just below the to-be-heated body (the workpiece 62).

As shown in Fig. 2, Fig. 3, Fig. 4 and Fig. 5, for each of the sheath heaters 32a and 32b, the two end members in the longitudinal direction thereof are moved up and down by the two support members 34. It is sandwiched from and supported. Each support member 34 includes a cylindrical fitting portion 36 having an arc-shaped cross section each having a predetermined length, and at both ends in the circumferential direction of the fitting portion 36, for example, as shown in FIG. 3. Similarly, a rectangular connecting piece 38 is formed in plan view. On one end side of the fitting part 36 in the longitudinal direction, as shown, for example in FIG. 1, FIG. 3, the cylindrical projection piece 40 whose arc cross section is formed is formed. The fitting portion 36, the connecting piece 38, and the protruding piece 40 are integrally formed.

On the other hand, the holding members 26 and 26 of the two mirror surface portions 12a and 12b are provided with, for example, circular through holes 42 facing each other on both sides of the longitudinal direction. The through holes 42 are provided on both sides in the longitudinal direction of the upper retaining plate 28.

The sheath heaters 32a and 32b are inserted between the through holes 42 of the upper retaining plates 28 and 28 that face each other. And both ends of the sheath heater 32a and 32b in the longitudinal direction are fitted from the up-down direction at the fitting part 36 of the support member 34, respectively. Moreover, the connecting piece 38 facing up and down is fixed by fixing means 44, such as a bolt and a screw. In this case, the sheath heater is supported by the support member 34 so that the protruding pieces 40 and 40 of the support member 34 protrude from the through holes 42 and 42 on the outer side of the upper retaining plates 28 and 28. 32a and 32b) are supported.

Next, a structure in which the two mirror surfaces 12a and 12b can be separated into two in the vertical direction will be described with reference to FIGS. 1, 2 and 5, for example.

The flange pieces 46a and 46b which protrude outside are respectively joined to the lower surface of the upper part 18a, 18b of the partial elliptic columnar surface part 16a, 16b. The flange pieces 46a and 46b have the cross-sectional U-shaped convex parts 48a and 48b which protrude below, respectively. On the other hand, the flange pieces 50a and 50b which protrude outside are respectively joined to the upper surface of the lower part 20a, 20b of the partial elliptic columnar surface part 16a, 16b. The flange pieces 50a and 50b have recesses 52a and 52b on which the convex portions 48a and 48b are mounted and engaged, respectively. And as the convex parts 48a and 48b of the flange pieces 46a and 46b are mounted and engaged on the recessed parts 52a and 52b of the upper surface of the flange pieces 50a and 50b, the partial elliptic column surface part 16a and 16b may be separated into two in the vertical direction.

The upper portions 18a, 18b and the flange portions 46a, 46b of the partial elliptic columnar portions 16a, 16b are integrally formed of a metal material such as stainless, and the lower portion ( 20a, 20b, flange parts 50a, 50b, and 1st reflective mirror surface parts 22a, 22b are integrally formed with metal materials, such as stainless steel, whose surface is formed in a mirror surface state. In this case, for example, the stainless steel plate is formed by being bent by metal plate work or the like. Moreover, you may use suitably what was mirror-processed by the plating etc. on the surface of a copper plate or an iron plate instead of a stainless steel plate, for example.

As the heat transfer element, in addition to the sheath heaters 32a and 32b, for example, a ceramic heater such as a silicon carbide heater that emits a lot of far infrared rays may be used. Sheath heaters 32a and 32b are used for low power, and silicon carbide heaters are used for high power. And a far infrared heater can also be used suitably as a heat transfer element.

In the electric burner 10 of this embodiment, as shown, for example in FIG. 1, FIG. 2, and FIG. 6, the 2nd reflective mirror surface part (for example of a cross section triangle) between two mirror surface parts 12a and 12b (for example, FIG. 54) is arranged. The second reflective mirror portion 54 includes, for example, two reflective surfaces 54a and 54b made of curved surfaces having a large curvature. One reflective surface 54a is disposed to face the open portion 14a of one mirror surface portion 12a, and the other reflective surface 54b is an open portion 14b of the other mirror surface portion 12b. It is arranged to face with. The 2nd reflective mirror surface part 54 is formed by the method similar to the formation method of the said partial elliptic columnar surface parts 16a and 16b, the 1st reflective mirror surface parts 22a and 22b, and the like.

In addition, in the electric burner 10, a catalyst film for promoting oxidation, for example, as an anti-deterioration coating on a surface to which at least a heat ray is irradiated from the mirror surface portions 12a and 12b and the first reflective mirror surface portions 22a and 22b. 56 is formed. In this case, the inner surfaces of the upper portions 18a and 18b and the lower portions 20a and 20b of the partial elliptic columnar portions 16a and 16b, the inner surfaces of the first reflective mirror portions 22a and 22b, and the second On the surfaces of the reflecting surfaces 54a and 54b of the reflecting mirror portion 54, a catalyst film 56 for promoting oxidation such as platinum and titanium oxide is formed.

In addition, in the electric burner 10, for example, as shown in Fig. 6, the lower portions 20a and 20b, the first reflective mirror surfaces 22a and 22b and the first reflection surfaces of the partial elliptic pillar surface portions 16a and 16b are formed. At least one of the reflective surfaces 54a and 54b of the two reflective mirror portions 54 is disposed so as to cover a protective member 58 having heat resistance and not interfering with the reflection of the hot wire. In this case, as the protective member 58, for example, aluminum foil formed of a material which is easy to replace and has a high heat ray reflectance is used. In addition, aluminum foil is attached to the surface of the base material which has heat resistance in the protection member 58 coat | covered by the lower part 20a, 20b of the partial elliptic pillar surface part 16a, 16b, and the 1st reflective mirror surface part 22a, 22b. What was formed is integrally formed. And as the protection member 58, you may use suitably the sheet-like heat resistant glass which is high in heat-wire passing rate and excellent in heat resistance, for example.

In the electric burner 10, for example, as shown in FIG. 6, the center of the sheath heater 32a and the sheath heater in one mirror surface portion 12a and the other mirror surface portion 12b opposite thereto. The angle X which the line which connects the center of (32b) and the major axis of one partial elliptic columnar surface part 16a makes is set suitably within the range of 0-90 degrees, for example.

In addition, the angle Y which the long axis line of the partial elliptical pillar surface part 16a and the 1st reflective mirror surface part 22a makes is set suitably within the range of 20-70 degrees, for example. In the case where the first reflective mirror portion 22a is a curved surface, the angle formed by a part of the curved surface and the major axis of the partial elliptic columnar surface portion 16a is appropriately set within a range of 20 to 70 °, for example. .

In the electric burner 10, in particular, as shown in FIGS. 1, 2, and 6, the two mirror surfaces 12a and 12b and the center line of the second reflective mirror surface portion 54 are centered. It is comprised so that the 1st reflective mirror surface parts 22a and 22b may be arranged symmetrically.

In the electric burner 10 shown in FIGS. 1-6, the supporting member 60, such as a mesh net or an iron grid, is mounted between the upper ends of the two mirror-surface parts 12a and 12b (refer FIG. 6). ). On the support member 60, as a to-be-heated body, the to-be-cooked object 62, such as meat and a fish, is placed, for example.

In the electric burner 10, since the sheath heaters 32a and 32b are disposed at a position sufficiently far from the bottom of the cooked material 62, the dregs, such as juice, oil and the like, from the cooked product 62 are almost removed. Since it is not attached, the generation of smoke can also be suppressed as much as possible. Therefore, in the electric burner 10, by suppressing the generation | occurrence | production of the smoke which generate | occur | produces when grilling fish or meat as much as possible, the collection | recovery apparatus of a smoke becomes unnecessary and can be used easily also in a normal household. Therefore, bulgogi, grilled fish, etc. can be cooked without generating smoke. In this case, cooking is possible in addition to the place equipped with the ventilation apparatus like the conventional sheet | seat part. When a silicon carbide heater is used, for example, as a heat transfer element, since the heating wire includes a lot of far infrared rays, it can be heated to the inside of the cooked food material and can be cooked by burning the surface appropriately while maintaining the moisture inside.

In the electric burner 10, the hot wire radiated from the sheath heaters 32a and 32b is reflected by the partial elliptic pillar surface portions 16a and 16b. Since the heating wires reflected by the partial elliptic pillar surface portions 16a and 16b are reflected by the first reflecting mirror surface portions 22a and 22b and are collected under the heating wire receiving member 60, the workpiece 62 is heated. You can. Further, by setting the intersection angle (Y in FIG. 6) formed by the long axis lines of the partial elliptic pillar surface portions 16a and 16b and the first reflective mirror surface portions 22a and 22b to a desired angle, In other words, depending on the size, according to the size of the supporting member 60, the irradiation angle of the hot wire irradiated to the lower side of the supporting member 60 can be appropriately changed.

That is, in the electric burner 10, for example, the interval in the width direction between two partially elliptic pillar surface portions 16a and 16b facing each other in FIG. 1, or the supporting member 60 and the first reflective mirror surface portion ( Since the space | interval etc. of the height direction between 22a, 22b) can be set suitably, design freedom becomes large.
