An upper heater 16 (see fig. 3) is attached to a rear surface side (upper side) of an upper surface 12a (see fig. 3) of the heating chamber 12. The upper heater 16 is used for grill heating and oven heating. The upper heater 16 corresponds to a heating unit described in claims.
Fig. 3 is an exploded perspective view showing the arrangement on the main body of the heating unit. Fig. 3 shows a state where the door 2, the operation panel 4, the outer frame 7, and the like are removed.
As shown in fig. 3, the upper heater 16 includes a mica heater (heater) 16a, a heat insulator 16b, an aluminum plate 16c, and a support plate (support member) 16 d.
The upper heater 16 is configured by stacking a mica heater 16a, a heat insulator 16b, an aluminum plate 16c, and a support plate 16d in this order from the heating chamber 12 side.
A heating wire is wound around the mica plate to form a flat shape, and the mica plate is pressed against the back surface side of the upper surface 12a of the heating chamber 12, thereby disposing the mica heater 16 a. The mica heater 16a heats the upper surface 12a of the heating chamber 12, and heats the food in the heating chamber 12 by radiant heat.
The mica heater 16a is formed in a rectangular shape at its outer peripheral edge, and the lead wires 16a1, 16a1 are extended from one side of the outer peripheral edge. The connectors 16a2 are provided at the leading ends of the lead wires 16a1 and 16a 1.
The heat insulating material 16b is overlapped on the upper surface of the mica heater 16 a. The heat insulating material 16b is formed by molding filiform glass fibers into a substantially rectangular plate shape. The outer peripheral edge of the heat insulating material 16b is formed larger than that of the mica heater 16 a.
Further, the heat insulator 16b is formed with a rectangular notch 16b1 in which the lead wire 16a1 is retracted. Further, on both sides of the cutout portion 16b1 of the heat insulating material 16b, fixing cutout portions 16b2 are formed.
The aluminum plate 16c is overlapped on the upper surface of the heat insulating material 16 b. The aluminum plate 16c is formed by forming an aluminum foil in a film shape, and is configured to cover the entire surface of the heat insulator 16 b. Further, rectangular notches 16c1 are formed in the aluminum plate 16c at positions corresponding to the lead lines 16a 1. The cutout portion 16c1 is formed larger than the cutout portion 16b1 of the heat insulating material 16 b.
The support plate 16d is a member in which the mica heater 16a, the heat insulator 16b, and the aluminum plate 16c are integrated and unitized, and is formed by cutting, bending, or the like, a sheet metal into a substantially rectangular shape.
Fig. 4 is a perspective view of the assembled state of the heating unit as viewed from the upper surface side. Fig. 4 shows a state in which the mica heater 16a, the heat insulator 16b, and the aluminum plate 16c are unitized by the support plate 16 d.
As shown in fig. 4, the support plate 16d includes: a top surface portion 16d1 covering the upper surface of the aluminum plate 16 c; a side surface portion 16d2 extending vertically downward from the front and rear edge portions of the top surface portion 16d 1; and side surface portions 16d3 extending vertically downward from the left and right edge portions of the top surface portion 16d 1. Rectangular notches 16d4 are formed in the top surface portion 16d1 and the side surface portion 16d3 at positions corresponding to the lead wires 16a 1.
Further, a recessed portion 16d5 recessed toward the aluminum plate 16c is formed in the center of the top surface portion 16d 1. The recess 16d5 is formed in a truncated cone shape. A screw hole h for fixing a screw is formed in the bottom surface of the recessed portion 16d 5. In addition, four corners of the top surface portion 16d1 are formed with quadrangular recessed portions 16d 6.
Further, reinforcing ribs r1, r2, r3, r4, and r5 are formed on the top surface portion 16d 1. The rib r1 is formed in a substantially rectangular shape around the recessed portion 16d 5. The rib r2 extends from each corner of the rib r1 toward the recess 16d 6. The rib r3 extends to connect the left front and rear recesses 16d 6. The rib r4 extends between the left and right recessed portions 16d 6. The rib r5 extends from the right-side recessed portion 16d6 to the cutout portion 16d 4.
Fig. 5 is an exploded perspective view of the heating unit as viewed from the bottom surface side.
As shown in fig. 5, a fixing claw 16e for fixing the mica heater 16a is formed on the lead line 16a1 side of the support plate 16 d. The fixing claw 16e is formed in the recessed portion 16d6, and is formed by cutting the support plate 16d (the top surface portion 16d1) and standing in an L shape. Fig. 5 illustrates one of the fixing claws 16 e.
Further, a fixing claw 16f is formed on the support plate 16d on the side opposite to the fixing claw 16 e. The fixing claws 16f are formed in L-shapes similarly to the fixing claws 16 e.
A circular cutout hole 16a3 is formed in the center of the mica heater 16 a. The slit hole 16a3 is for allowing the recess 16d5 to escape, and suppresses excessive radiant heat from being generated in the center portion.
Fig. 6 is a perspective view of the assembled state of the heating unit as viewed from the bottom surface side.
As shown in fig. 6, the mica heater 16a, the heat insulator 16b, and the aluminum plate 16c are accommodated in the recess of the support plate 16d, and the mica heater 16a is locked by the fixing claws 16e and 16 f. Thus, the fixing claws 16e and 16f provided on the support plate 16d fix the mica heater 16a, the heat insulator 16b, and the aluminum plate 16c together to form a unit.
The side surface portion 16d3 on the lead wire 16a1 side also forms a fixing portion 16g bent in the horizontal direction. A fixing screw hole h is formed in the fixing portion 16 g. The side surface portion 16d3 opposite to the lead wire 16a1 is formed with a fixing portion 16h bent in the horizontal direction. A fixing screw hole h is formed separately in the fixing portion 16 h.
A circular round hole 16b3 is formed in the heat insulating material 16b at a position overlapping the slit hole 16a 3. The circular hole 16b3 has a diameter (diameter) sufficiently smaller than the notch hole 16a 3. Also, the recessed portion 16d5 is exposed from the circular hole 16b 3. Further, although not shown, holes for exposing the recessed portions 16d5 are also formed in the aluminum plate 16 c.
Fig. 7 is a cross-sectional view schematically showing a state of being cut along line a-a of fig. 1.
As shown in fig. 7, the upper heater 16 is fixed to the upper surface (outer surface) 12a of the main body 1 in a state where the mica heater 16a, the heat insulator 16b, and the aluminum plate 16c are integrated (in a single component) by the support plate 16 d. The mica heater 16a is disposed so as to be in surface contact with the upper surface 12 a.
A tubular lower heater (not shown) is provided around a rotary antenna (not shown) below the platen 19 on the bottom surface of the heating chamber 12. The heat generated by the lower heater heats the food in the heating chamber 12 through the platen 19.
As shown in fig. 7, radiant heat Q1 directed toward the heating chamber 12 is generated from the mica heater 16 a. The radiant heat Q2 directed upward from the mica heater 16a passes through the heat insulating material 16b, reaches the aluminum plate 16c, is reflected by the aluminum plate 16c, and returns to the heating chamber 12. By disposing the aluminum plate 16c, which has been conventionally disposed on the outer side of the support plate 16d, on the inner side of the support plate 16d in this manner, the radiant heat Q2 from the mica heater 16a can be efficiently transmitted to the heating chamber 12 by the aluminum plate 16c, which has a higher reflection efficiency than the support plate 16 d.
In the heating cooker 100, the mica heater 16a, the heat insulator 16b, and the aluminum plate 16c are unitized by the support plate 16d, so that the ease of assembling the upper heater 16 is improved, and the workability of attaching the upper heater 16 to the main body 1 is also improved.
In addition, a concave portion 16d6 is formed on the aluminum plate 16c side of the support plate 16 d. Thereby, a space S is formed between the top surface portion 16d1 (support plate 16d) and the aluminum plate 16 c. In this way, the space S can be used as an air insulating layer, and radiation heat of the mica heater 16a can be suppressed from being radiated to the outside of the support plate 16 d.
As described above, the heating cooker 100 of the first embodiment includes the heating chamber 12 for accommodating a food (an object to be cooked), and the upper heater 16 (heating means) disposed on the upper surface 12a (outer surface) of the heating chamber 12 and heating the food. The upper heater 16 is configured by stacking a mica heater 16a, a heat insulator 16b, an aluminum plate 16c, and a support plate 16d in this order from the heating chamber 12 side. The support plate 16d is fixed to the upper surface 12a in a state of supporting the mica heater 16a, the heat insulator 16b, and the aluminum plate 16c (see fig. 7). Accordingly, the aluminum plate 16c changes from the outer side to the inner side of the support plate 16d, so that the efficiency of reflecting radiant heat from the mica heater 16a is increased, and the thermal efficiency of the heating chamber 12 can be improved. As a result, the output of the mica heater 16a can be reduced, and the energy saving performance can be improved. In addition, the start of oven heating and barbecue heating is improved, and the energy-saving performance is improved.
In the first embodiment, the support plate 16d is formed with the recessed portion 16d6, and the recessed portion 16d6 is formed as a protruding portion protruding toward the aluminum plate 16c, so that a space S is formed between the aluminum plate 16c and the support plate 16d (see fig. 3 to 7). This allows the space S to be used as an air insulating layer, and therefore, the radiation heat Q2 (see fig. 7) can be prevented from being radiated to the outside of the support plate 16d, and the thermal efficiency of the heating chamber 12 can be improved. As a result, the output of the mica heater 16a can be reduced, and the energy saving performance can be improved.
(second embodiment)
Fig. 8 is a sectional view showing a heating unit of a heating cooker according to a second embodiment. Note that the same components as those of the first embodiment are denoted by the same reference numerals, and redundant description thereof is omitted.
As shown in fig. 8, a heating cooker 100A according to the second embodiment includes an upper heater 16A (heating means) as heating means. The upper heater 16A is configured by stacking a mica heater 16A and a heat insulating material 16b in this order from the heating chamber 12 side, and the mica heater 16A and the heat insulating material 16b are supported by a support plate 16i (support member), and the support plate 16i is fixed to the upper surface 12a of the heating chamber 12.
The support plate 16i is an aluminum plate, and is processed into the same shape as the support plate 16d of the first embodiment.
As shown in fig. 8, the radiant heat Q2 directed upward from the mica heater 16a passes through the heat insulating material 16b, reaches the aluminum support plate 16i, is reflected by the support plate 16i, and returns to the heating chamber 12. By making the support plate 16i of aluminum in this way, the same reflection effect of radiant heat Q2 as that of the aluminum plate 16c can be obtained, and the reflection efficiency can be improved compared to the conventional one, and heat can be efficiently transferred to the heating chamber 12. As a result, the mica heater 16a can be changed to a low-power type, and energy saving performance can be improved.
Further, the mica heater 16A and the heat insulator 16b are unitized by the support plate 16i, so that the assembling property of the upper heater 16A is improved, and the workability of attaching the upper heater 16A to the main body 1 is also improved. Further, the aluminum plate 16c can be eliminated, and therefore, the assemblability of the upper heater 16A can be further improved.
In the second embodiment, the support plate 16i is made of aluminum, but the material is not limited to this, and may be made of stainless steel (SUS) or a steel plate plated with aluminum.
(third embodiment)
Fig. 9 is a sectional view showing a heating unit of a heating cooker according to a third embodiment.
As shown in fig. 9, a heating cooker 100B of the third embodiment includes an upper heater 16B (heating means) as heating means. The upper heater 16B is configured by stacking a mica heater 16a and a vacuum heat insulating material 16j in this order from the heating chamber 12 side, the mica heater 16a and the vacuum heat insulating material 16j are supported by a support plate 16d (support member), and the support plate 16d is fixed to the upper surface 12a of the heating chamber 12.
The vacuum heat insulating material 16j is configured by, for example, wrapping a laminated glass wool or the like with a cover material (a thin-walled aluminum film, a laminated film having a metal deposition layer), and then evacuating the inside of the cover material. Such a vacuum heat insulating material 16j can improve heat insulating properties as compared with the heat insulating material 16b made of glass wool.
In this way, in the third embodiment, by providing the vacuum heat insulating material 16j instead of the heat insulating material 16b, the upward radiant heat Q2 of the mica heater 16a can be blocked by the vacuum heat insulating material 16j and directed toward the heating chamber 12 side, and therefore, heat can be efficiently transferred to the heating chamber 12. As a result, the mica heater 16a can be changed to a low-power type, and energy saving performance can be improved.
In the third embodiment, the mica heater 16a and the vacuum heat insulating material 16j are unitized by the support plate 16d, so that the assembling property of the upper heater 16B is improved, and the workability of attaching the upper heater 16B to the main body 1 is also improved. Further, since the aluminum plate 16c is not required, the assemblability of the upper heater 16A can be further improved.
In addition, in the third embodiment, since the temperature of the top plate of the outer frame 7 can be lowered by providing the vacuum heat insulating material 16j, the outer frame 7 can be eliminated, and the structure of the heating cooker 100B can be simplified and reduced in weight.
The present embodiment has been described above with reference to the drawings, but the present embodiment is not limited to the above description, and includes various modifications. For example, in the present embodiment, the case where the heating means (the upper heater 16) is applied to the upper surface 12a side of the heating chamber 12 has been described, but the present invention may be applied to the lower surface side of the heating chamber 12 or may be applied to the left and right side surfaces.
