Description

  The present invention relates to a heating cooker such as a hot plate that performs cooking by placing an object to be cooked on a plate.

A hot plate as this type of heating cooker is, for example, a plate as a cooking container that is detachably installed in a plate storage unit, as disclosed in Patent Document 1, for example, heating means such as an induction heating coil or a sheathed heater. The cooking object on the plate is heated by the heating means for cooking. However, if the entire surface of the plate is simply heated by the heating means, for example, when a small amount of food is heated, the area where nothing is placed on the plate is also heated, resulting in unnecessary power consumption. . Also, if the baked meat is not taken out of the plate each time, there is a complaint that the meat on the plate will burn immediately.
JP 2001-340227 A

  In order to eliminate such dissatisfaction, an H & A (with half and all function) hot plate having the structure shown in FIGS. 21 and 22 has been proposed. In the figure, reference numeral 1 denotes a bottomed frame that forms the outline of the hot plate, and 2 is a heat shield fixed to the inner bottom of the frame 1 via a spacer (not shown). Two sheathed heaters, that is, a half heater 4A and an all heater 4B are provided so as to be supported by the heater presser 3 standing on the bottom surface. The frame 1, the heat shield plate 2, the heater retainer 3, the half heater 4A and the all heater 4B constitute a hot plate main body.

  Reference numeral 5 denotes a plate-like plate placed on the heat shield plate 2, and the thickness of the plate 5 is substantially uniform and is in contact with the upper portions of the half heater 4A and the all heater 4B. The half heater 4A and the all heater 4B are both formed in a serpentine shape when viewed from the upper surface of the plate 5, but one half heater 4A is disposed only in the half region on one side of the plate 5, and the other The all heater 4 </ b> B is disposed over almost the entire area of the plate 5.

  6 is a detachable heat master that is inserted into one side surface of the frame 1. When the heat master 6 is mounted, a rod-shaped heat-sensitive portion 7 that protrudes from the tip of the heat master 6 contacts the lower surface of the plate 5. The temperature is detected. The heat master 6 cuts off the half heater 4A and the all heater 4B so that the plate 5 reaches the set temperature based on the temperature information from the heat sensitive part 7, and cooks the food on the plate 5 by heating. Here, by operating a change-over switch 8 protruding on one side surface of the frame 1, either half heater 4A or all heater 4B is cut off.

  In this case, when the all heater 4B is energized, the whole plate 5 is heated, so that the whole plate 5 is heated. However, when the half heater 4A is energized, one half of the plate 5 is directly heated. The remaining half of the plate 5 serves as a heat retaining region that receives heat conduction from one half. Therefore, when there are few objects to be heated or when it is desired to keep the baked meat without getting burned, the changeover switch 8 can be appropriately operated to switch to the preferred power-off operation of the half heater 4A.

  However, in the above configuration, there are two heaters as heating means, a changeover switch 8 is required, and other relay lead wires are also required in accordance with the number of heaters. Was invited.

  As another problem, the H & A hot plate as shown in FIG. 23 or FIG. 24 is a convex portion for attaching a plurality of grooves 10 along one direction so that the oil content of the grilled meat does not adhere to the food. 11 is provided on the surface of the plate 5, but since the plate 5 is a so-called integral type, heat is transmitted to an unnecessary portion such as a side wall portion or a flange of the plate 5 to cause unnecessary power consumption, Extra heating time was also required. In addition, when various types of plates 5 are exchanged and used for cooking purposes, the plate 5 is an integral type that occupies almost the entire surface of the hot plate as described above, so that the size is large and the cost is increased. Sometimes there was a large number of plates 5 which was inconvenient.

  As shown in FIGS. 25 and 26, there has been proposed a solution in which a part of the plate 5 can be replaced with a Kisekae plate 21 which is a plurality of different plates as shown in FIGS. Similarly, the Kisekae plate 21 is provided with a convex portion 23 on the surface thereof for attaching a plurality of groove portions 22, and is detachably provided in a stepped hole portion 31 provided substantially at the center of the plate 5. On the other hand, the heating means here is constituted by a single heater 4 and is arranged across the part of the Kisekae plate 21 and the other part of the plate 5. Since the Kisekae plate 21 occupies only a part of the plate 5, the Kisekae plate 21 has good storage capacity and can reduce the cost. However, the heating time is almost the same as that of a general integrated plate. Necessary and useless electricity costs.

  In order to eliminate such waste, it is considered that the Kisekae plate 21 may be placed over almost the entire portion where the heater 4 is disposed. In this case, however, the heat retaining area which is a part other than the Kisekae plate 21 is almost all. It was lost and the practicality was poor (see FIGS. 27 and 28).

  The present invention has been made in consideration of the above-mentioned circumstances, and provides a cooking device that is excellent in storability and can cope with various variations of cooking without wasteful heating. Objective.

  In the heating cooker according to the first aspect of the present invention, various plates can be used in the heating region of the plate in accordance with the purpose of cooking, so that various variations of cooking can be handled. In addition, the plate occupies only the hole portion and is excellent in storage.

  In the heating cooker according to the second aspect of the present invention, there is a portion where the energizing portion of the heating means is not directly opposed. Therefore, in the portion outside the plate, the heat from the contact portion with the plate and the slight radiant heat of the heating means It can only be transmitted. Therefore, excessive heat is not transmitted in the outer part of the plate, and cooking can be performed on the plate without unnecessary heating.

  According to the configuration of the first aspect of the present invention, it is possible to provide a cooking device that is excellent in storability and can cope with various variations of cooking.

  According to the configuration of the second aspect of the present invention, it is possible to provide a cooking device that is excellent in storability and can cope with various variations of cooking without wasteful heating.

  Hereinafter, each Example of the heating cooker in this invention is described with reference to an accompanying drawing. In addition, all the heating cookers in each Example are hot plates. The same parts as those in the conventional example are denoted by the same reference numerals, and the description of the same parts is omitted as much as possible.

  1 to 5 show a first embodiment of the present invention. The heat shield 2 constituting the main body has a first plate 5 (see FIGS. 1 to 3) or a second plate 5A (see FIG. 1). 4 and FIG. 5) are detachably provided. The planar shapes of these plates 5 and 5A are the same, but the bottom shapes are different. That is, the first plate 5 serving as a plate with heat insulation is formed in a flat shape having no step from the heating region Z1 on one side to the heat insulation region Z2 on the other surface side when viewed from above. The bottom surface of the second plate 5A serving as the entire surface heating plate is not flat, and a hanging portion 41 that forms a step is formed on the bottom surface of the heating region Z1 on the other surface side with respect to the bottom surface of the heating region Z1 on one surface side. The The drooping portion 41 is formed integrally with the second plate 5 </ b> A and has a shape in which the lower end abuts over substantially the entire stepped portion 42 of the heater 4 described later.

  On the other hand, the heating means in this embodiment is composed of a single heater 4 and is not provided with a change-over switch 8 as shown in FIG. The heater 4 is arranged over almost the entire area of the plates 5 and 5A when viewed from the upper surface of the plates 5 and 5A, but when viewed from the side, the heater 4 corresponds to the remaining surface side of the plates 5 and 5A, for example, A stepped portion 42 is formed that falls downward by about 5 mm. When the first plate 5 is mounted on the heat shield plate 2, the entire bottom surface of the first plate 5 is flat. Therefore, on one side of the first plate 5, there is a heating region Z1 that is close to or in contact with the heater 4. On the remaining surface side, a heat insulating region Z2 is formed in which a gap 43 is formed with the heater 4. On the other hand, when the second plate 5A is mounted on the heat shield plate 2, the drooping portion 41 formed on the bottom surface and located on the remaining surface side not only on one side but also on the remaining surface side. Also, a heating region Z1 that is close to or in contact with the heater 4 is formed. In each of the plates 5 and 5A, a direction restricting portion (not shown) is provided so that the plates 5 and 5A are not attached to the left and right sides when they are attached to the heat shield plate 2 as the main body. Thereby, for example, when the second plate 5A is mounted on the opposite side, the heater 4 can be prevented from being forced by the hanging portion 41.

  Next, the operation of the above configuration will be described. When it is desired to keep the cooking object warm on a part of the plate, the first plate 5 is placed on the heat shield plate 2 of the main body. At this time, since the entire bottom surface of the first plate 5 is formed flat, a heating region Z1 that contacts the heater 4 is formed on one side, and a heat retaining region Z2 that does not contact the heater 4 on the other surface side. Is formed. Therefore, when the heater 4 is energized, heat from the contacting heater 4 is directly conducted in the heating region Z1 and becomes high temperature, while in the heat retaining region Z2, the heat from the heater 4 passes through the gap 43 and the heating region Z1. It conducts only indirectly, and the temperature is lower than that of the heating zone Z1. Therefore, the food to be cooked placed in the heating region Z1 is cooked to a high temperature, and the food to be cooked placed in the heat retaining region Z2 is kept warm to the extent that it does not burn.

  On the other hand, when it is desired to perform cooking on the entire surface of the plate, the second plate 5A is placed on the heat shield plate 2 of the main body. At this time, the drooping portion 41 of the second plate 5A is in contact with the stepped portion 42 of the heater 4, and the heating region Z1 where the bottom surface of the second plate 5A is in contact with almost the entire heater 4 is the second plate 5A. Occupies almost the entire surface. Therefore, when the heater 4 is energized, the heat from the heater 4 is directly conducted on almost the entire surface of the second plate 5A, and the cooked object placed at any position on the second plate 5A is cooked. Is cooked to high temperature.

  As described above, in the present embodiment, in the heating cooker that cooks by heating the plate 5 having a flat bottom surface by the heater 4 that is a heating means, the step portion 41 is partially provided on the heater 4 at the bottom of the plate 5. A gap 43 is provided between the heater 4 and the plate 5 to provide a heat retaining function.

  In this way, when the heater 4 is energized, the stepped portion 41 provided in the heater 4 causes the plate 5 to become high temperature in a portion close to (or in contact with) the heater 5 and to have a gap 43 between the heating means. In the portion, the heat from the heater 4 is not sufficiently transmitted and becomes a low temperature, resulting in a temperature difference between the two portions. Therefore, although it is the single heater 4, the part of the plate 5 close to the heater 4 is set as a heating region Z1 suitable for cooking, and the part of the plate 5 having the gap 43 between the heater 4 is suitable for heat insulation. It can be used simultaneously as the heat insulation area Z2. Therefore, it is not necessary to provide the heaters 4 for cooking heating and heat insulation, respectively, the number of parts can be reduced, the structure can be simplified, and the cost can be reduced.

  In addition, the second plate 5A whose bottom face is close to or in contact with almost the entire heater 4 is provided so as to be exchangeable with the first plate 5 so that the second plate 5A as a whole is heated and cooked. It becomes possible.

  Next, a second embodiment of the present invention will be described with reference to FIGS. The heating means in the present embodiment is composed of a single heater 4 as in the first embodiment, but has no stepped portion when viewed from the side, and is formed in a flat linear shape. Instead, the bottom surface of the first plate 5 that is used for both heat retention and heating has a stepped portion 45 that is lifted upward, for example, by about 5 mm with respect to one side that forms the heating region Z1, and the remainder that forms the heat retaining region Z2. It is formed on the surface side. On the other hand, another second plate 5A whose entire surface is the heating region Z1 has a hanging portion 46 formed in the stepped portion 45 so as to be close to or in contact with the heater 4 not only on one side but also on the remaining side. The The hanging portion 46 is formed integrally with the second plate 5A and has a shape in which the lower end abuts over substantially the entire heater 4 described later.

  When the first plate 5 is mounted on the heat shield plate 2, one side of the first plate 5 is close to or in contact with the heater 4, and a gap 43 is formed between the remaining side and the heater 4. The On the other hand, when the second plate 5A is mounted on the heat shield plate 2, the heater 4 is formed not only on one side but also on the remaining side by the hanging part 46 formed on the bottom side and located on the remaining side. Get close to or in contact with. In this embodiment as well, a direction restricting portion (not shown) is provided so that the plates 5 and 5A are not attached to the left and right sides when attached to the heat shield plate 2 as the main body.

  When the first plate 5 is placed on the heat shield plate 2 of the main body, the first plate 5 is formed with a heating region Z1 that contacts the heater 4 on one side thereof, and contacts the heater 4 on the remaining surface side. The heat insulation area | region Z2 which is not performed is formed. Therefore, when the heater 4 is energized, heat from the contacting heater 4 is directly conducted in the heating region Z1 and becomes high temperature, while in the heat retaining region Z2, the heat from the heater 4 passes through the gap 43 and the heating region Z1. It conducts only indirectly, and the temperature is lower than that of the heating zone Z1. Therefore, the food to be cooked placed in the heating region Z1 is cooked to a high temperature, and the food to be cooked placed in the heat retaining region Z2 is kept warm to the extent that it does not burn.

  On the other hand, when the second plate 5A is placed on the heat shield plate 2 of the main body, the hanging portion 46 of the second plate 5A comes into contact with the heater 4, and the heating region Z1 occupies almost the entire surface of the second plate 5A. . For this reason, when the heater 4 is energized, heat from the heater 4 is directly conducted on almost the entire surface of the second plate 5A, and the cooked object placed at any position of the second plate 5A is not cooked. Cooked at high temperature.

  As described above, in the present embodiment, in the cooking device that cooks by heating the plate 5 with the heater 4 serving as a heating means, the step portion 45 is provided at the bottom of the plate 5, and the gap between the heater 4 and the plate 5 is provided. A gap 43 is formed to provide a heat retaining function.

  In this way, when the heater 4 is energized, the stepped portion 45 at the bottom of the plate 5 causes the plate 5 to become hot at a portion close to (or in contact with) the heater 5, and a portion having a gap 43 between the heating means. Then, the heat from the heater 4 is not sufficiently transmitted and the temperature becomes low, and a temperature difference is generated between the two parts. Therefore, although it is the single heater 4, the part of the plate 5 close to the heater 4 is set as a heating region Z1 suitable for cooking, and the part of the plate 5 having the gap 43 between the heater 4 is suitable for heat insulation. It can be used simultaneously as the heat insulation area Z2. Therefore, it is not necessary to provide the heaters 4 for cooking heating and heat insulation, respectively, the number of parts can be reduced, the structure can be simplified, and the cost can be reduced.

  In addition, the second plate 5A whose bottom face is close to or in contact with almost the entire heater 4 is provided so as to be exchangeable with the first plate 5 so that the second plate 5A as a whole is heated and cooked. It becomes possible. In the second plate 5A of the present embodiment, the hanging portion 46 is formed in the step portion 45, but a plate having a flat bottom surface may be used as it is, and a step portion is provided in the existing heating means. There is an advantage that can be realized only by adding the first plate 5 to the cooking device that is not.

  Moreover, in the said 1st Example and 2nd Example, as shown to FIG. 11 and FIG. 12, the hole part 31 is provided in the heating area | region of the 1st plate 5 to which the heater 4 adjoins, and it respond | corresponds to this hole part 31. A Kisekae plate 21 which is a replaceable plate having a size to be replaced may be provided. The Kisekae plate 21 is provided with convex portions 23 on its surface for attaching a plurality of groove portions 22 along one direction so that the oil content of the grilled meat does not adhere to the food. Several kinds of Kisekae plate 21 are prepared, and any one of them can be used while being freely replaced. For example, in addition to the grooved plate for grilled meat shown in FIGS. 11 and 12, there are a perforated plate for preventing oil scattering, a plate for takoyaki, a grilled plate, and the like. These shapes will be described later. Further, a protrusion 35 is formed on the entire circumference of the hole portion 31 so that the juice from the object to be cooked does not flow into the hole portion 31.

  In this way, by providing a replaceable Kisekae plate 21 in the heating area Z1 of the first plate 5, various Kisekae plates 21 can be used in the heating area Z1 in accordance with the purpose of cooking. At the same time, the food to be cooked can be kept warm in the heat retaining zone Z2.

  Next, a third embodiment of the present invention will be described with reference to FIGS. The heating means in this embodiment includes two heaters as shown in FIGS. 21 to 24, that is, a half heater 4A and an all heater 4B. And based on the temperature information from the heat sensitive part 7, the heat master 6 cuts off electricity to the half heater 4A and the all heater 4B so that the plate 5 becomes a set temperature, and cooks the food on the plate 5 by heating. At the same time, by operating the changeover switch 8, either the half heater 4A or the all heater 4B is disconnected.

  The removable plate 5 is provided with a hole 31 in the heating area Z1 half on one side, and a Kisekae plate 21 as another plate is placed in the hole 31. The planar shape of the Kisekae plate 21 is formed to a size that the half heater 4 </ b> A just fits. That is, the energizing portion of the heating means (half heater 4A) used when heating one surface of the plate 5 is provided in a region smaller than the Kisekae plate 21 and the heat retaining region from the Kisekae plate 21 through the hole 31. Heat conduction is performed in Z2. Also in this embodiment, a direction restricting portion (not shown) is provided so that the plates 5 and 5A are not attached to the left and right sides when attached to the heat shield plate 2 as the main body.

  In the above configuration, when the all heater 4B is energized, the entire plate 5 is heated, so-called full-surface heating, and the entire plate 5 can be cooked. On the other hand, when the half heater 4A is energized, the Kisekae plate 21 in the half on one side of the plate 5 becomes a heating region Z1 where the plate 5 is directly heated, while the remaining half of the plate 5 is a heat retaining region that receives heat conduction from the half on one side. Z2. In particular, the other half of the plate 5 has a relationship that the planar shape of the Kisekae plate 21 is formed so as to fit in the half heater 4A, so that heat from the contact portion of the Kisekae plate 21 or from the half heater 4A. It has a structure that transmits only a small amount of radiant heat and hardly transmits excess heat. Therefore, it is excellent in energy saving and the heating speed of the Kisekae plate 21 is faster than that of the integrated plate.

  The Kisekae plate 21 shown in FIG. 13 and FIG. 14 is a grooved plate for grilled meat, and as described above, the surface is provided with convex portions 23 for attaching a plurality of groove portions 22 along one direction. ing. In addition, several kinds of Kisekae plate 21 are prepared, and any one of them can be used while being freely replaced. The Kisekae plate 21A shown in FIG. 15 and FIG. 16 is a perforated plate that prevents oil from splashing, and a plurality of holes 51 are formed therein. 17 and 18 is a plate for takoyaki having a plurality of bowl-shaped portions 52 suitable for making takoyaki. Further, the Kisekae plate 21 </ b> C shown in FIGS. 19 and 20 is a grilled plate of a simmering direct fire style. Any one of these Kisekae plates 21 and 21A to 21C is mounted in the hole 31 of the plate 5 according to the purpose of cooking.

  Thus, the Kisekae plates 21 and 21A to 21C occupy only a part of the plate 5, so that the storage property is good and the cost can be reduced. Further, when the half heater 4A is energized, only the portions of the Kisekae plates 21, 21A to 21C are heated, so that energy saving is excellent and the remaining heat time is shortened. Therefore, the usability as a heating cooker is improved. Furthermore, since Kisekae plates 21, 21A to 21C and full-surface heating / single-side heating of plate 5 can be selected, various variations of cooking can be performed, and the width can be expanded.

  As described above, in the present embodiment, in the heating cooker that cooks by heating one surface or the entire surface of the plate 5 by the half heater 4A and the all heater 4B as heating means, the hole portion 31 is provided on one surface of the plate 5. In this hole portion 31, Kisekae plates 21, 21A to 21C, which are a plurality of different plates, are provided so as to be replaceable.

  In this way, when the entire surface of the plate 5 is heated by the all heater 4B, the entire plate 5 can be used as a heating region Z1 suitable for cooking, and when one side of the plate 5 is heated by the half heater 4A, the one side is cooked. The remaining surface can be used as a heat retaining region Z2 suitable for heat insulation. In addition, according to the purpose of cooking, various Kisekae plates 21, 21A to 21C can be used in the heating region Z1 of the plate 5, so that various variations of cooking can be supported. In addition, the Kisekae plates 21, 21A to 21C occupy only one side of the plate, and are excellent in storage properties.

  In the present embodiment, the energizing portion of the half heater 4A when heating one surface of the plate 5 is provided in an area smaller than the Kisekae plates 21 and 21A to 21C.

  As described above, when one side of the plate 5 is heated by the half heater 4A, the energization part of the half heater 4A is not directly opposed to the part of the plate 5, so that the remaining surface of the plate 5 is the Kisekae plates 21, 21A to 21C. Only the heat from the contact portion and the slight radiant heat of the half heater 4A are transmitted. Therefore, excess heat is not transmitted to the plate 5, and cooking can be performed on the Kisekae plates 21, 21A to 21C without performing unnecessary heating.

  In addition, this invention is not limited to the said Example, In the range of the summary of this invention, it can change suitably. For example, you may comprise combining the characteristic part of each Example, respectively. Moreover, you may utilize the heating coil which electromagnetically heats a plate as a heating means.
