Description

  The present invention relates to a heating cooker including a main body case in which a heating body is accommodated and a cooking container placed on the heating body.

  In this type of cooking device, generally, a cooking container having a dish shape is called a hot plate, and a cooking container having a pan shape is called a grill pan.

  The main body case has a space opened on the upper surface, and is constituted by one or a plurality of resin molded members. A heating element, a thermo stud, and the like are disposed in the opening space of the main body case.

  The heating body is supported so as to be fixed or detachable with respect to the main body case. As the heating element, a cast-in heater, a sheathed heater, or the like is used. A heat shield is attached to the main body case or the heating body via a heat insulating spacer or the like.

  The heat shield is provided so as to be located mainly between the bottom of the main body case and the heating body. Other devices arranged below the main body case and the heating body are protected from the radiant heat of the heating body by a heat shield.

  Furthermore, a resin guard surrounding the cooking container placed on the heating body is formed in the main body case. This resin guard reduces the exposure of the cooking container and prevents burns.

  The structure of the resin guard widely adopted has inner and outer double side walls, and a space is provided between the inner and outer side walls for the purpose of heat insulation.

  When the resin guard becomes hot, the discoloration and deformation are accelerated, and the user is surprised when touched. In order to avoid these problems, conventionally, the side wall of the cooking vessel and the resin guard are separated as much as possible to attenuate the radiant heat from the side wall of the cooking vessel and prevent the resin guard from being heated to a high temperature.

  In addition, there is also one in which the heat shield is placed along the inner side wall of the resin guard and the inner side wall of the resin guard is hidden as much as possible from the side wall of the cooking container to prevent the resin guard from being heated to high temperature (Patent Document 1).

Japanese Patent Laid-Open No. 11-46976

  However, if the high temperature of the resin guard is prevented only by the separation between the side wall of the cooking container and the resin guard, the gap between them becomes conspicuous, and there is a problem that the appearance of the product is impaired.

  Further, when the heat shield plate is placed along the inner side wall of the resin guard, heat conduction is generated from the heat shield plate, which is heated by the radiant heat of the heating body, to the resin guard. For this reason, there is a problem that the resin guard becomes hotter than when the high temperature is prevented only by the above-described separation.

  Then, the subject of this invention is preventing the high temperature of a resin guard even if it narrows between the side wall of a cooking container and the resin guard in the heating cooker which provided the resin guard in the main body case.

  In order to achieve the above object, the present invention includes a main body case in which a heating body is accommodated, a cooking container placed on the heating body, and a heat shield plate positioned between the heating body and the main body case. The cooking device provided with a resin guard surrounding the cooking container in the main body case, comprising a heat reflecting plate located between a side wall of the cooking container and the resin guard, the heat reflecting plate being the cooking container and the A configuration provided in non-contact with the heat shield is adopted.

Specifically, by adopting a configuration including a heat reflecting plate positioned between the side wall of the cooking container and the resin guard, radiant heat from the side wall of the cooking container is reflected by the heat reflecting plate, and the resin guard is It becomes difficult to be heated. Further, by adopting a configuration in which the heat reflecting plate is provided in non-contact with the cooking container and the heat shielding plate, the heat reflecting plate becomes lower in temperature than the heat shielding plate that receives the radiant heat of the heating body and the cooking container. Thermal conduction does not occur between the heat reflecting plate and the high temperature part. The radiant heat reflection and the heat conduction blocking action prevent the resin guard from being heated to a high temperature.
Moreover, since a heat | fever reflecting plate is a plate body, it can install without extending between the side wall of a cooking container, and the resin guard. That is, the heat reflecting plate does not hinder the space between the side wall of the cooking container and the resin guard.
Therefore, according to the said structure, even if it narrows between the side wall and resin guard of a cooking vessel, the high temperature of a resin guard can be prevented.

  In addition, it is not necessary to arrange | position a heat | fever reflection board in the whole region between the side wall and resin guard of a cooking vessel. For example, the resin guard may be provided in a necessary range of the resin guard so that the temperature of the resin guard is equal to or lower than a predetermined value in a portion of the resin guard where the distance from the side wall of the cooking container is narrow. Moreover, a heat | fever reflecting plate can be abbreviate | omitted in the part from which the radiant heat from the side wall of a cooking vessel is interrupted | blocked by the heat shield in the resin guard.

  The heat reflecting plate is preferably a metal plate, particularly a material having excellent corrosion resistance and gloss such as stainless steel. The metal plate has better heat resistance than the resin. Corrosion resistance is effective in preventing corrosion due to blowing. Glossiness is effective in improving the appearance of the product.

  If the structure which provided the clearance gap between the said resin guard and the said heat reflecting plate in the said structure is employ | adopted, the heat transfer between a heat reflecting plate and the resin guard will be reduced by the air heat insulation effect of the said clearance gap. For this reason, the high temperature of the resin guard is further prevented.

  In the configuration in which the gap is provided, by adopting a configuration in which the gap is provided by forming a plurality of ribs on the resin guard and the heat reflecting plate is supported by the plurality of ribs, Among these, a gap is provided between the portion supported by the plurality of rib structures and the resin guard. For this reason, it becomes difficult to dent the heat reflecting plate. Further, since the heat reflecting plate and each rib are in linear contact, heat conduction between them is prevented as much as possible.

  In the above configuration, if a configuration in which an upper end portion higher than the heat reflecting plate is formed in a portion outside the heat reflecting plate in the resin guard, it is easy to touch the resin guard before the hand touches the heat reflecting plate. Become. For this reason, contact with the heat reflecting plate, which is higher in temperature than the resin guard, is prevented, and the usability is improved.

  In addition, in the said structure, since a heat | fever reflecting plate becomes temperature lower than a heat insulating board, even if a heat | fever reflecting plate and a hand contact, there also exists an advantage that it is hard to produce a burn from the case of a heat insulating board.

  As described above, according to the present invention, in the heating cooker in which the side periphery of the main body case is made of a resin guard, the resin guard can be prevented from being heated even when the side wall of the cooking container and the resin guard are narrowed. .

Hereinafter, a steam port case according to an embodiment of the present invention will be described with reference to the accompanying drawings.
As shown in FIGS. 1 and 2, the heating cooker according to the embodiment includes a main body case 2 in which the heating body 1 is accommodated, a cooking container 3 placed on the heating body 1, and the heating body 1 and the main body case 2. And a heat shield 4 positioned between the two.

  The main body case 2 is an assembly in which an upper case 2a in which a space opening on the upper surface is formed and a lower case 2b in which an outer bottom surface is formed are vertically aligned.

  Each of the upper and lower cases 2a, 2b is integrally molded with resin.

  The heating body 1 is supported above the bottom of the upper case 2a. As the heating element 1, a heating plate in which an electric heater is cast is used.

  As the cooking container 3, a pan-shaped one that is spread upward is used. A handle 31 is provided on the side wall of the cooking container 3 so as to be opposed to each other in the circumferential direction. As shown in FIG. 1 and FIG. 3, flanges 32 and 32 are provided in most of the upper end of the side wall of the cooking container 3 between the handles 31 and 31.

  The main body case 2 is provided with a resin guard 21 that surrounds a portion of the cooking container 3 lower than the handle 31 and the flange 32. The resin guard 21 includes inner and outer double side walls 22 and 23 and has a structure in which a space is provided between the inner and outer side walls 22 and 23.

  The inner side wall 22 of the resin guard 21 is composed of an inner peripheral wall continuously provided at the bottom of the upper case 2a, and is substantially vertical (may be vertical). An intermediate recess 22a is formed on the inner wall 22 of the resin guard 21 in order to prevent the flow of blown down.

  The outer wall 23 of the resin guard 21 includes an outer peripheral wall 23a that hangs outward from the inner wall 22 and a side peripheral wall 23b of the lower case 2b.

  The handle 31 and the flange 32 are located above the resin guard 21. A recess 24 is formed in the resin guard 21 so that the lower end of the grip of the handle 31 is accommodated.

  The height of the resin guard 21 can be appropriately changed according to the shape of the cooking container 3, the support height, and the like. For example, in the case where a plurality of cooking containers 3 having different heights such as a shallow pan, a deep pan, and a grilled plate are provided, the height of the resin guard 21 can be set corresponding to the height of the highest cooking container.

  The heat shield plate 4 is formed in a dish shape and is attached to the heating body 1. The side periphery of the heat shield 4 is positioned higher than the middle recess 22 a of the resin guard 21. Therefore, a portion of the inner wall 22 of the resin guard 21 that is lower than the middle recess 22 a is protected from the radiant heat of the heating body 1 and the cooking container 3 by the heat shield plate 4.

  The heating cooker according to this embodiment includes a heat reflecting plate 25 located between the side wall of the cooking container 3 and the resin guard 21.

  As shown in FIG. 1 and FIG. 2, the heat reflecting plate 25 is formed so that the inner wall 22 of the resin guard 21 is higher than the middle recess 22 a and extends along the most part between the recesses 24, 24 in the circumferential direction. It is provided substantially vertically (or vertical). By making the inner wall 22 substantially vertical and separately forming the heat reflecting plate 25, it becomes easy to form the heat reflecting plate 25 vertically. As a result of providing the heat reflecting plate 25 substantially vertically, the distance between the heat reflecting plate 25 and the side wall of the cooking container 3 can be increased, so that the inner wall 22 can be shielded to the maximum extent.

In this embodiment, the reason why the heat reflecting plate 25 is provided in a portion higher than the middle step recess 22 a is that the portion is not protected by the heat shield plate 4.
The reason why the heat reflecting plate 25 is provided in a large portion between the concave portions 24 and 24 in the circumferential direction is that the distance between the concave portion 24 and the side wall of the cooking container 3 is between the concave portions 24 and 24 in the circumferential direction. This is because it is narrow and is likely to become high temperature. The heat reflecting plate 25 can also be provided over the entire circumference of the portion of the inner wall 22 of the resin guard 21 that is higher than the middle recess 22a.
The reason why the heat reflecting plate 25 is provided along the inner wall 22 of the resin guard 21 is that the installation space can be made as small as possible.

  The heat reflecting plate 25 is formed from a metal plate. As the heat reflecting plate 25, a resin plate or a ceramic surface provided with a reflecting layer can be used. The reason why the heat reflecting plate 25 is made of a metal plate is that it is relatively excellent in terms of durability and low cost. Note that the exposed surface of the heat reflecting plate 25 is smooth, improving the reflectivity and preventing dirt from adhering.

  The heat reflecting plate 25 has a flange portion 25a at its upper end and a plurality of claw portions 25b at its lower end. The resin guard 21 has a groove 22b that hooks the flange 25a from above. As shown in FIG. 4, the insertion hole for the claw portion 25b is formed in the middle recess 22a. When the hook portion 25a is hooked in the groove 22b, each claw portion 25b protrudes from each insertion port. When the claw portion 25b is twisted in this state, the heat reflecting plate 25 is fixed in a state of being separated from the upper side edges of the cooking container 3 and the heat shield plate 4.

  By the above fixing, the heat reflecting plate 25 is determined at a position along the inner wall 22 of the resin guard 21. Therefore, as shown in FIG. 1, the contact between the heat reflecting plate 25, the cooking container 3, and the heat shield plate 4 is reliably prevented. The mounting structure of the heat reflecting plate 25 can be changed as appropriate.

According to said structure, the heat | fever reflection board 25 becomes low temperature rather than the heat insulation board 4 which receives the radiant heat of the heating body 1 or the cooking vessel 3. FIG. Thermal conduction does not occur between the heat reflecting plate 25 and the high temperature portions 3 and 4.
Further, the heat reflecting plate 25 reflects the radiant heat from the side wall of the cooking vessel 3 in a portion of the resin guard 21 that is not protected by the heat shielding plate 4 and is short in distance from the side wall of the cooking vessel 3. To do. Thereby, the high temperature of the part concerned is prevented, As a result, the high temperature of the resin guard 21 whole is prevented.
Therefore, the heating cooker according to this embodiment can prevent the resin guard 21 from becoming hot even if the space between the side wall of the cooking container 3 and the resin guard 21 is narrowed.

  In the heating cooker according to this embodiment, the flange portion 25a of the heat reflecting plate 25 is positioned between the inner wall 22 and the flange 32 of the cooking container 3 so that the radiant heat from the flange 32 is reflected. I have to.

  Here, the handle 31 of the cooking container 3 is generally low in heat radiation because high temperature is prevented by adopting a wooden grip, a resin-coated grip, or the like. Therefore, the concave portion 24 of the resin guard 21 is less likely to be heated than other portions. In this embodiment, when adopting a configuration in which the entire handle 31 is provided integrally with the cooking container 3, the recess 24 may be protected by the heat reflecting plate 25.

  In addition, as shown in FIGS. 2 and 3, the heating cooker according to this embodiment includes a plurality of portions of the inner wall 22 of the resin guard 21 covered with the heat reflecting plate 25 at regular intervals in the circumferential direction. Ribbed ribs 26 are formed. Each rib 26 is formed in a vertical protruding shape in the vertical direction in order to avoid undercut.

  As shown in FIGS. 4 and 5, the height of each rib 26 is generally in contact with the plate surface of the attached heat reflecting plate 25. For this reason, a gap S is provided between the heat reflecting plate 25 and the inner wall 22 of the resin guard 21 between the ribs 26 adjacent in the circumferential direction.

  Due to the air insulation effect associated with the formation of the gap S, heat transfer between the heat reflecting plate 25 and the resin guard 21 is reduced. For this reason, the high temperature of the resin guard 21 is further prevented.

  In addition, a gap S is provided between a portion of the heat reflecting plate 25 supported by the rib structure including the ribs 26 and the inner wall 22 of the resin guard 21. For this reason, the heat reflecting plate 25 is difficult to dent.

  Each rib 26 has a linear protrusion shape and comes into linear contact with the heat reflecting plate 25. For this reason, heat conduction between the heat reflecting plate 25 and the resin guard 21 is prevented as much as possible.

  Further, since each rib 26 supports the heat reflecting plate 25, the inclination of the plate surface of the heat reflecting plate 25 is prevented when the claw portion 25b is inserted into the middle recess 22a. For this reason, the nail | claw part 25b can be inserted easily.

  In addition, in the heating cooker which concerns on this embodiment, in the state which the front-end | tip of the collar part 25a of the heat | fever reflecting plate 25 contacted the bottom of the groove | channel 22b, between the upper end of the inner wall 22 of the resin guard 21, and the upper board of the collar part 25a. A minute gap is generated. Due to this minute gap, heat conduction between the flange 25a and the inner wall 22 is prevented.

  Furthermore, in the heating cooker according to this embodiment, by adopting a twisted claw in the claw portion 25b, heat conduction between the claw portion 25b and the middle recess 22a is prevented.

  In the heating cooker according to this embodiment, an upper end portion 27 higher than the flange portion 25 a of the heat reflecting plate 25 is formed in a portion of the resin guard 21 outside the heat reflecting plate 25. Thereby, the contact with the heat | fever reflecting plate 25 used as the temperature higher than the resin guard 21 and a hand is prevented.

  Note that the upper end portion 27 of the resin guard 21 is located inside the flange 32 of the cooking vessel 3. This is because the upper end 27 can prevent the spill from the cooking container 3 from entering the groove 22b.
