Description

  The present invention relates to an induction heating cooker that induction-heats a cooking container with a heating coil.

  In general, a system kitchen incorporating a built-in type induction heating cooker or gas cooker has a strict module restriction of 600 mm width (inner width of 560 mm). In FIG. 7, the external appearance perspective view of the conventional built-in type induction heating cooking appliance is shown. Moreover, the top view of the induction heating cooking appliance of the state integrated in the system kitchen is shown to Fig.8 (a), and a front view is shown to FIG.8 (b). The inner width of the cabinet 20 sandwiched between the cabinet inner side plates 21a and 21b of the system kitchen is regulated to 560 mm, and a drop hole 23 having a lateral width of 560 mm is also opened in the kitchen top plate 22. Accordingly, the main body housing 90 that is dropped into the cabinet 20 from the drop hole 23 during assembly is also designed to have a width of 560 mm. On the other hand, the top plate 91 of the induction heating cooker has a lateral width (for example, 750 mm) larger than 560 mm in order to conceal the drop hole 23 and hook it around the periphery.

  In the conventional induction heating cooker, since the main body casing 90 other than the top plate 91 is accommodated in the cabinet 20, the coil storage portion 93 for storing each heating coil 92, the grill portion 94, the heating coil 92, and the grill portion 94. It is necessary to store the control unit 95 for storing the control board and the like in the main body housing 90 having a width of 560 mm or less. Therefore, even if the horizontal width of the top plate 91 is increased to 560 mm or more, the coil storage portion 93 having a horizontal width of 560 mm or less is restricted, and the heating coil arrangement region B is also defined to have a horizontal width of 560 mm or less.

  Therefore, for example, in Patent Document 1, when a plurality of heating coils are arranged at predetermined intervals in a limited heating coil arrangement region B, cooking containers such as large-sized pans are juxtaposed side by side and used as cooking containers. In addition to suppressing the squeeze to the side, avoiding troublesome heating forms and improving the handling of the cooking container.

JP 2005-61678 A

  Since the conventional induction heating cooker is configured as described above, even if the width of the top plate is enlarged, the arrangement area of the heating coil is restricted by the width in the cabinet and the width of the drop hole. A sufficient distance between the coils could not be secured, and a useless space had to be opened on the left and right of the top plate. Further, even if the arrangement of the heating coil is devised as in Patent Document 1, the arrangement area of the heating coil is limited in the first place. There was a problem that the diameter of the material could not be increased.

  The present invention has been made to solve the above-described problems, and is adapted to induction heating cooking that can be adapted to a conventional system kitchen and can be laid out by a heating coil without being restricted by the cabinet inner width and the drop hole width. The purpose is to provide a vessel.

  An induction heating cooker according to the present invention is housed in a main body housing having at least a grill portion, a coil storage portion formed on the upper surface of the main body housing with a width larger than the width of the main body housing, and the coil storage portion. The heating coil and a top plate provided on the upper surface of the coil storage portion are provided.

  According to the present invention, since the width of the coil storage portion is wider than the width of the main body casing, the main body casing is adapted to the conventional system kitchen, and is not limited by the cabinet inner width and the drop hole width. An induction cooking device capable of layout can be provided.

It is an external appearance perspective view which shows the structure of the induction heating cooking appliance which concerns on Embodiment 1 of this invention. The state which incorporated the induction heating cooking appliance shown in FIG. 1 in the system kitchen is shown, FIG. 2 (a) is a top view, FIG.2 (b) is a front view. It is a left view explaining the assembly method of the induction heating cooking appliance which concerns on Embodiment 1. FIG. An example of the layout of the top plate of the induction heating cooker is shown, FIG. 4A is a plan view of the top plate 11 according to the first embodiment, and FIG. 4B is a plan view of a conventional top plate 91. An example of the layout of the top plate of the induction heating cooker is shown. FIG. 5A is a plan view of the top plate 11 according to the first embodiment, and FIG. An example of the layout of the operation part of the top plate of the induction heating cooker is shown, FIG. 6A is a plan view of the top plate 11 according to the first embodiment, and FIG. 6B is a plan view of a conventional top plate 91. is there. It is an external appearance perspective view which shows the structure of the conventional induction heating cooking appliance. The state which integrated the conventional induction heating cooking appliance in the system kitchen is shown, Fig.8 (a) is a top view, FIG.8 (b) is a front view.

Embodiment 1 FIG.
1 is an external perspective view showing a configuration of an induction heating cooker according to Embodiment 1 of the present invention. Moreover, the top view of the state which incorporated the induction heating cooking appliance in the system kitchen in FIG. 2 (a) is shown, and the front view is shown in FIG.2 (b). FIG. 3 is a left side view illustrating a method of assembling the induction heating cooker into the system kitchen. In addition, since the system kitchen incorporating the induction heating cooker according to the first embodiment has the same configuration as the system kitchen of the prior art (FIG. 8) described above, the same reference numerals are given and description thereof is omitted.

  The induction heating cooker according to the first embodiment includes a top plate 11 on which a cooking container is placed, a main body housing 10 that houses a grill portion 14 and a control portion 15, and a width that is wider than the width of the main body housing 10. And a coil storage part 13 for storing the heating coil 12. The control unit 15 stores a control board and the like for controlling each part of the induction heating cooker. Since the heating coil 12 is stored in the coil storage portion 13 below the top plate 11, the heating coil 12 cannot be seen from the outside when the top plate 11 is opaque. The outer shape of the heating coil 12 is illustrated above.

  In order to accommodate the main body housing 10 in the cabinet 20, the lateral width of the main body housing 10 is set to be 560 mm or less of the inner width of the cabinet 20. On the other hand, in order to house the coil storage unit 13 in the kitchen top plate 22 instead of the cabinet 20, the thickness of the coil storage unit 13 is reduced to be less than the thickness of the kitchen top plate 22 (usually around 30 to 40 mm). Since the coil storage part 13 can be accommodated in the kitchen top plate 22 by making the coil storage part 13 thinner, the lateral width is not restricted by the inner width of the cabinet 20. Therefore, the lateral width of the coil storage portion 13 is expanded to an inner width of the cabinet 20 of 560 mm or more. The thickness of the heating coil 12 stored in the coil storage unit 13 is set to be equal to or less than the thickness of the coil storage unit 13.

  In order to assemble this induction heating cooker into the system kitchen, it is necessary to widen the width of the drop hole 23 in advance in accordance with the width of the coil storage portion 13. The conventional drop hole 23 (see FIG. 8) is enlarged to match the width of the coil storage portion 13 of the induction heating cooker according to the first embodiment to obtain an enlarged drop hole 23a shown in FIG. As shown in FIG. 3, as shown in FIG. 3, first, the main body casing 10 is dropped so as to be inserted obliquely from the enlarged drop hole 23a, and the top plate 11 is hooked on the kitchen top plate 22 around the enlarged drop hole 23a. At this time, the main body housing 10 follows the conventional size of 560 mm, and therefore fits within the inner width 560 mm of the cabinet 20. On the other hand, the coil storage unit 13 is housed in the kitchen top plate 22 instead of the cabinet 20. Moreover, although the drop hole 23 was expanded to the expansion drop hole 23a, since the periphery of this expansion drop hole 23a is covered with the top plate 11, there is no apparent change in the assembled state. In addition, when replacing the induction heating cooker of the first embodiment with a conventional standard product, it is necessary to fill the left and right extended opening portions of the enlarged drop hole 23a and return to the drop hole 23. Even if the treatment is performed, the seam is covered with the top plate 11, so that there is no apparent change in the assembled state.

  Thus, since there is no restriction | limiting of the cabinet 20 and the drop hole 23 which are 560 mm in the horizontal width of the coil storage part 13, the horizontal width of the coil storage part 13 can be arbitrarily formed in 560 mm or more. Therefore, the arrangement | positioning area | region (heating coil arrangement | positioning area | region A shown in FIG. 1) of the heating coil 12 stored in the coil storage part 13 is expanded, the diameter of the heating coil 12 can be enlarged, and the freedom degree of arrangement | positioning increases. The coil storage unit 13 is also provided with a cooling means including a fan or the like for cooling the heating coil 12. However, since the volume of the coil storage unit 13 is increased, the degree of freedom of the installation position of the cooling means is increased.

Next, the layout of the top plate 11 will be described. Below, the layout of the top plate 11 is demonstrated using the induction heating cooking appliance provided with the three heating coils 12a, 12b, and 12c as an example.
FIG. 4 (a) is a plan view of the induction heating cooker according to Embodiment 1, and FIG. 4 (b) is a plan view of the conventional induction heating cooker. As shown in FIG. 4A, since the heating coil arrangement area A spreads over the entire top plate 11, for example, a large heating coil 12a having a diameter of about 280 mm can be arranged. Since the heating coil 12a is large, the entire bottom surface of the large cooking container 30 such as a frying pan can be heated.
On the other hand, as shown in FIG. 4B, the large heating coil 12a having a diameter of 280 mm cannot be arranged in the conventional heating coil arrangement region B which is limited by the inner width of the cabinet 20, and the conventional heating having a diameter of about 220 mm is not possible. The coil 92a is disposed. Therefore, the heating coil 92a is small and the entire bottom surface of the large cooking container 30 cannot be heated uniformly, resulting in uneven temperature, resulting in poor efficiency. Moreover, if a part of cooking container 30 covers the other heating coil 92c, the heating coil 92c cannot be used. Further, both left and right end portions of the top plate 91 become useless areas. For example, if the horizontal width of the top plate 91 is 750 mm, a region having a width of about 100 mm on each of the left and right sides is wasted.

Fig.5 (a) is a top view of the induction heating cooking appliance by Embodiment 1, FIG.5 (b) is a top view of the conventional induction heating cooking appliance. As shown in FIG. 5A, the center distance between the left and right heating coils 12a and 12b can be increased by arranging the large heating coils 12a and 12b on the left and right. For this reason, even when cooking containers 31 and 32 are respectively placed on the left and right heating coils 12a and 12b, there is room between the cooking containers 31 and 32, and the user can move to the other cooking container while cooking with one cooking container. There is little risk of touching the hand, and the risk of burns and the like can be reduced.
On the other hand, as shown in FIG.5 (b), in the conventional induction heating cooking appliance, it is necessary to avoid a handle in order to mount the cooking containers 31 and 32 in the right and left heating coils 92a and 92b. Moreover, since there is no room between the cooking containers 31, 32, there is a risk of burns and the like.

FIG. 6A is a plan view of the induction heating cooker according to Embodiment 1, and FIG. 6B is a plan view of the conventional induction heating cooker. FIG. 6 illustrates the layout of the operation unit. As shown in FIG. 6A, the top plate 11 includes a left coil operating unit 16a for operating the left heating coil 12a, a right coil operating unit 16b for operating the right heating coil 12b, and a central coil. A central coil operating part 16c for operating the heating coil 12c and a grill operating part 17 for operating the grill part 14 are provided. Since the control board hangs down in each operation part 16a, 16b, 16c, 17, it is necessary to arrange in the coil storage part 13, ie, the heating coil arrangement area A, but since the heating coil arrangement area A is wide, each operation part 16a, The left and right widths of 16b, 16c, and 17 can be expanded, and an operation unit layout having a space can be realized. Thereby, for example, the grill operation unit 17 and the coil operation units 16a, 16b, and 16c can be clearly separated by arranging the grill operation unit 17 outside the coil operation units 16a, 16b, and 16c. And operability is improved.
On the other hand, as shown in FIG. 6 (b), in the conventional induction heating cooker, a left coil operation unit 96a is disposed near the left heating coil 92a in order to improve operability, and near the right heating coil 92b. However, in this case, since the heating coil arrangement region B is narrow, the grill operation part 97 has to be arranged between the left and right coil operation parts 96a and 96b. Therefore, the grill operating unit 97 and the coil operating units 96a, 96b, and 96c cannot be separated, and the operability becomes complicated.

  Moreover, when the exhaust port 18 connected to the coil storage part 13 or the grill part 14 is formed in the surface of the top plate 11, the opening area of this exhaust port 18 can also be expanded (FIG. 6 (a)).

As described above, according to the first embodiment, the induction heating cooker has a lateral width larger than the lateral width of the main body casing 10 on the main body casing 10 having the grill portion 14 and the control section 15 and on the upper surface of the main body casing 10. The kitchen top plate 22 is configured to include the formed coil storage unit 13, the heating coil 12 stored in the coil storage unit 13, and the top plate 11 provided on the upper surface of the coil storage unit 13. The main body housing 10 is dropped into the cabinet 20 from the opened enlarged drop hole 23a, the coil storage portion 13 is accommodated in the kitchen top plate 22, and the top plate 11 is hooked on the periphery of the enlarged drop hole 23a. For this reason, a large-sized heating coil can be installed and the freedom degree of arrangement | positioning of a heating coil also improves. As a result, it is possible to provide an induction heating cooker capable of laying out the heating coil 12 without being restricted by the inner width of the cabinet 20 and the width of the drop hole 23 while being adapted to a conventional system kitchen.
In particular, when there are two or more heating coils 12 stored in the coil storage unit 13, the center distance between the left and right coils can be increased by increasing the size of each heating coil 12.
Moreover, since the arrangement width of each coil operation part 16a, 16b, 16c and the grill operation part 17 can be expanded by enlarging the horizontal width of the coil storage part 13, the operation part layout with a space | interval can be implement | achieved, and each coil operation part Visibility and operability are improved by separately arranging 16a, 16b, and 16c and the grill operating portion 17.
