Description

  The present invention relates to a heating cooker that heats and cooks an object to be heated via a cooking container placed on a top plate.

  Conventionally, a heating cooker is a drop-in type having a plurality of mouths (here, three mouth types) as shown in FIGS. 4 and 5, for example, but needing a driving mechanism such as a roaster function, heating means, cooling fan, etc. is omitted. A case main body 1 and a top plate 2 provided so as to cover the upper portion of the case main body 1 are schematically configured. In this case, the frame 3 is attached to the peripheral portion of the top plate 2 to form the top plate 4, and therefore the peripheral portion of the top plate 2 is partially covered by the frame 3 (hereinafter referred to as the engagement allowance). It is in. Further, as the heating means, for example, heating means 5 and 6 arranged side by side consisting of induction heating coils, and heating means 7 consisting of a radial heater made of nichrome wire are arranged in the center in the back, and these Each is formed in a substantially circular shape.

  Thus, the top plate 2 positioned above and close to the heating means 5, 6, 7 has a ring-shaped frame slightly larger in diameter than the circular outer shell lines of the heating means 5, 6, 7. Each of the displayed heating parts 8, 9, and 10 is formed on the left, right, and central parts by printing, and is shown to the user as an area where a cooking container such as a pan (not shown) can be effectively heated for convenience. . The coil diameter L which is the diameter of the left and right heating means 5 and 6 is normally 180 mm, and therefore the left and right heating parts 8 and 9 which are the ring-shaped frames are set larger in diameter than this. (Details will be described later).

  However, in particular, FIG. 5 shows a schematic configuration in which a drop-in type heating cooker is incorporated in a system kitchen or the like. Generally, a drop hole 12 having a lateral width Z of 560 mm is formed in the countertop 11 of the kitchen. This is standardized in the industry, and accordingly, the width Y of the case body 1 dropped into the case is designed and manufactured to be 543 mm or less, for example, less than the dimension Z. On the other hand, the top plate 4 has a lateral width dimension X (for example, 600 mm) slightly longer than the lateral width dimensions Z and Y so as to conceal the drop hole 10 and be held at the periphery thereof.

  Specifically, as shown in FIG. 4, the top plate 2 has an effective width dimension V of 550 mm excluding the engagement margin due to the frame 3 at the periphery, and therefore the width dimension W at the left and right and front of the frame 3 is 25 mm. It is said. And among the heating parts of this top plate 2, for example, a pot (not shown) having a maximum diameter as an applicable cooking container can be juxtaposed to the heating parts 8 and 9 arranged side by side. Now, assuming that the maximum diameter of the pan is U, when the pans placed on the heating units 8 and 9 arranged on the left and right sides are juxtaposed with a predetermined interval T not easily touching, the pans are tops. The dimension is set so as not to protrude from the left and right ends of the plate 2. In FIG. 4, the maximum diameter U of the pan is the same as that of the ring-shaped frame showing the regions of the left and right heating units 8 and 9, and this can be regarded as the outer shell of the pan (not shown).

  In FIG. 4, the center line α of the top plate 2 also shows the center part of the left and right lateral width, and the center line β of the left and right heating parts 8 and 9 is the corresponding heating means 8 composed of induction heating coils. , 9 and the coil pitch S, which is the pitch dimension between them, is obtained after ensuring the predetermined interval T. In this example, the interval T between the central portions is usually set to 30 mm, the coil pitch S is set to 285 mm, and the maximum diameter U of the pan is set to 255 mm (U = ST). As a result, each shortest distance R from the outer shell of each pan to each left and right end of the top plate 2 has a margin of 5 mm, the depth dimension M of the top plate 2 is 439 mm, and from the outer shell of the pan to the front end. Although the shortest distance N is relatively 27.5 mm, there is no margin in the left-right direction, so it can be said that this is an acceptable practical limit for the maximum diameter U of the pan.

  The basis of the above-mentioned pan interval T (30 mm) is that it is difficult for the handle of the pan juxtaposed side by side to come into contact with the side surface of the other pan, or even when it is in a position where it does not come into contact. It is set for reasons such as difficulty in handling. Conventionally, since the horizontal dimension V of the top plate 2 is a relatively small dimension of 550 mm as described above, each heating unit is used with respect to 275 mm of the distance Q from the central part corresponding to half of the top plate 2 to each left and right end part. The distance O to the center portion (center line β) of 8 and 9 is 142.5 mm, and the ratio is about 52% from the center portion to each of the left and right end portions. , 9 are arranged closer to the left and right ends.

  Thus, when the pan with the maximum diameter U is juxtaposed side by side, the center portion has a predetermined interval T (30 mm) on the top plate 2, whereas the left and right end portions have the shortest distance. R (5 mm) is not enough, so that the pan may protrude in the left-right direction, or the top plate 2 may be spilled or scattered to contaminate the periphery. In particular, in the drop-in type, the upper surface of the counter top 11 of the kitchen and the mounting surface of the top plate 2 have a flat shape that makes the step as small as possible from the viewpoint of usability and design, or is almost the same surface. For this reason, even if the pan protrudes to the left or right, there is a risk that it will be overlooked without any significant change in the mounting state.As a result, the pan will be displaced and the heating efficiency will decrease, or the protruding pan will come into contact with other things. There is also concern about the problem of heating.

  In addition, various cooking utensils and small parts on the countertop 11 are easy to move to the top plate 2 side. In this case, since the heating parts 8 and 9 are close to each other as described above, heating is performed by mistake. There is also a possibility of doing so. Further, in the kitchen, there is a case where the side wall of the cupboard placed on the countertop 11 is arranged close to either the left or right end of the top plate 2 and is subject to such space restrictions. In the case of installation conditions, problems such as the pan touching the cupboard or the handle of the pan is difficult to grasp and the handleability is reduced.

In addition, in some types of drop-in type cooking devices having left and right heating units, an operation display unit may be provided on substantially the same surface as the top plate to improve usability (for example, Patent Documents). 1), however, the operation display unit is not only required to take out the pan and to take measures against heat from the pan, but when it protrudes, the operation display unit is not easy to use.
JP 2002-349877 A

  The problem that is going to be solved is that when a cooking container such as a large pot is placed side by side on the top plate, it tends to protrude from the top plate in the left-right direction and easily spills and scatters around the top plate. In the case of an installation condition that invites a simple heating form or is subject to space restrictions at the left and right end portions, there is a difficulty in that the handling property of the cooking container is lowered.

In order to solve the above problems, a heating cooker according to the present invention includes a plurality of heating means disposed on the left and right in the case main body for heating an object to be heated via a cooking container, and below the plurality of heating means. A top plate comprising a top plate provided so as to cover above the heating means and the roaster, and a frame attached to a peripheral portion of the top plate, and the top plate includes the heating means and the top plate. When the heating part which mounts the said cooking container in the corresponding right-and-left position is provided, and the cooking container of the maximum diameter which makes the said cooking container juxtaposed with a predetermined space | interval in these heating parts is mounted, this predetermined | prescribed The distance from the outer shell of the cooking container to the left and right end portions excluding the engagement margin of the frame of the top plate is longer than the interval of (the invention of claim 1).

Then, in what the claim 1 Symbol placement, it be in configuration of a drop-in type, the width dimension of the case body 560mm or less, and set the width dimension of the top plate except the engagement allowance of the frame than 700mm (Invention of claim 2 ).

  According to the first aspect of the cooking device of the present invention, when the cooking container having the maximum diameter is placed on the top plate with a predetermined interval, the cooking vessel is further separated from the outer shell of the cooking container by the predetermined interval. Because it is configured to increase the distance to the left and right ends of the top plate, even in a heating cooker that drops and arranges the case body integrated with the roaster within the limited dimensions that are industry standard, The maximum allowable diameter of the cooking container with a predetermined interval is prevented from protruding in the left-right direction from the top plate to avoid a troubled heating mode, and there is room on the left and right ends to allow the cooking container to There is no hindrance to handling.

According to claim 2 , by increasing the width of the top plate without enlarging the case main body, it is possible to easily perform the assembling work by dropping into the kitchen or the like as in the past, while maintaining the top plate Then, it is possible to effectively use a cooking container having an enlarged diameter, which has advantages such as improved usability.

FIG. 1 is a plan view of a cooking device alone, FIG. 2 is an external perspective view incorporated in a kitchen, and FIG. 3 is a front view showing a cutaway main portion. Of these, FIG. 2 and FIG. In addition to the description, FIG. 1 will mainly describe the arrangement of main parts. This heating cooker is in a so-called three-mouth type, and is mainly composed of a case main body 21 having a rectangular box shape as in the prior art, and a heat-resistant glass top plate 22 provided so as to cover the upper part. wearing the frame 23 to the periphery of the top plate 22 constitute a Tokoro Iten plate 24.

  Among them, the case body 21 includes a heating unit and an operation unit 25 to be described later, a cooling fan (not shown), and thermal power control of the heating unit based on a control program stored in advance by receiving input signals such as various detection signals. And a drive mechanism section such as a control circuit for driving and controlling an inverter circuit (not shown). A roaster 26 provided with a heating means using a sheathed heater (not shown) is integrally provided below the heating means and on the left side of the operation unit 25, and is disposed in the case body 21 in a compact manner.

  On the other hand, the top plate 22 is provided with air intake / exhaust means having a cover member 27 attached to the rear end, and the heating parts 28 to 30 are ring-formed by printing, for example, at three positions corresponding to the heating means described later on the upper surface of the front plate 22. It is formed by displaying a frame. And, on the near side corresponding to these heating parts 28-30, there are provided heating power display parts 31-33 of heating means described later, which are constituted by a plurality of LED light emitting elements in a chained state, The heating power is adjusted based on the setting operation by the unit 25, and the strength degree can be easily determined from the position of the lighting display.

  The heating units 28 to 30 indicate a mounting region for effectively heating a cooking container (not shown), and are displayed with a diameter larger than that of the heating means described later, and in particular, before this. The diameter dimensions of the ring-shaped frames that are the left and right heating units 28 and 29 are also represented as, for example, the diameter dimension of a pan (indicated by symbol K in FIG. 1) as an allowable maximum diameter cooking container, and the arrangement relationship thereof Details of this will be described later.

  The heating means in the present embodiment will now be described. The heating means 34 and 35 comprising induction heating coils having different outputs at positions below the top plate 22 corresponding to the heating units 28 and 29 arranged on the left and right sides. Are arranged side by side in the horizontal direction in the figure, and corresponding to the heating part 30 located in the back of the center, heating means 36 composed of a radiant heater made of nichrome wire is disposed, and these heating means are almost circular in this embodiment. It is formed in a shape (others may be a polygonal shape), and is fixed to the upper part in the case main body 21 via an appropriate attachment member.

  Incidentally, the output of each heating means is, for example, a maximum output of 3 kilowatts (KW) for the left heating means 34 (corresponding to the heating part 28), and a maximum output of 2.kw for the right heating means 35 (corresponding to the heating part 29). The maximum output is set to 0 kilowatts (KW), and the heating means 36 (corresponding to the heating unit 30) in the center of the radiant heater is set to 1.2 kilowatts (KW). I have to.

  In addition, magnetic shield plates 37 and 38 made of aluminum and made of a ring-shaped horizontal plate are provided in the vicinity of the outer periphery of the heating means 34 and 35 disposed on the left and right of these (see FIG. 3). Prevents leakage of electromagnetic waves from However, the left end portion of the left magnetic shield plate 37 and the right end portion of the right magnetic shield plate 38 are formed with bent portions 37a and 38a that are bent vertically downward, for example, and so-called left and right end portions have a slight horizontal portion. However, the surface area is secured by the rising portion to enable the magnetic shielding function, and the case body 21 is compactly arranged in the limited space space in the left-right direction, which is the industry standard.

  Further, the operation unit 25 described above will be further described with reference to FIG. 3. The operation unit 25 includes various switches, operation dials corresponding to the heating means, and the like, for example, the power switch 39 and the dial 40a from the left in the drawing. ˜40d are provided, and each of the dials has a switch function that is turned on / off in response to the heating power adjustment of the heating means and the repeated operation of the push, and the dial 40a has the heating means 34 on the left side and the dial 40b has The roaster 26 (seeds heater), the dial 40c can control the central heating means 36, and the dial 40d can control the right heating means 35.

  Then, in the cooking device having the above configuration, the case body 21 is inserted so as to be dropped from the drop hole 43 of the counter top 42 of the kitchen 41 as shown in FIG. 3, and the case body 21 is pulled to the periphery of the drop hole 43. It is hung and held and incorporated into the kitchen 41 as a so-called drop-in type cooking device. In this case, the shape (size) of the drop hole 43 is, as described above, the standard width dimension Z is 560 mm. Therefore, the horizontal dimension Y of the main body case 21 is also set to 543 mm, for example, 560 mm or less.

  On the other hand, for example, the horizontal dimension A of the top plate 24 is set to 750 mm, which is 25% higher than the conventional level, and the effective horizontal dimension B of the top plate 22 is set to 714 mm, which is about 30% higher than the conventional level. The frame 23 attached to the peripheral edge of the top plate 22 is attached to the top plate 22 through an appropriate engagement allowance (for example, 4.5 mm), and the frame width I at the left and right and the front is 18 mm. In addition, the same code | symbol is attached | subjected about the dimension equivalent to the past.

  As described above, by increasing the width B of the top plate 22 on which the pan is placed, the arrangement of the main parts in this embodiment is as shown in FIG. First, the diameter dimension of at least the left and right heating units 28 and 29 is set to, for example, 300 mm, which is common to the maximum allowable pot diameter K as described above, and is larger than the conventional maximum pot diameter U255 mm. The diameter has been increased. On the other hand, the corresponding coil diameter L of the left and right heating means 34, 35 is 180 mm as in the conventional case, and is disposed compactly in the case body 21 having the same lateral width Y (543 mm) as in the conventional case. ing.

  Here, when the definition of the maximum allowable pan diameter K described above is described, the size of the pan can be juxtaposed on the left and right heating units 28 and 29 while ensuring a predetermined interval dimension T. It is a prerequisite. Thus, in the center portion indicated by the center line α of the top plate 22, the coil pitch C indicated by the center line β of the left and right heating means 34, 35 is set to 330 mm while ensuring 30 mm as the gap distance T between the pans. In the embodiment, the pan diameter K can be set to 300 mm, which is about 20% higher than the conventional one (K = C−T). Accordingly, the left and right heating parts 28 and 29, which are ring-shaped frames having the same diameter as the pot diameter K, are also formed at positions that are substantially evenly distributed to the left and right via a predetermined space dimension T of 30 mm. Yes.

However, in order to finally determine the maximum diameter of the pan diameter K, in this embodiment, in addition to the increase in diameter, it is determined by securing a distance margin in the left and right end directions, which has been insufficient in the past. The
Incidentally, the shortest distance D from the outer shell of the pot having a pot diameter K to the left and right ends is set to be as large as 42 mm (T <D), that is, the maximum pot diameter K is set with respect to a predetermined interval dimension T30 mm in the center. Even if the pans are juxtaposed side by side, a longer distance is secured at the left and right ends of the top plate 22 than between the pans in the center.

  Moreover, the tendency can be known also from the following point about the said arrangement configuration. That is, the center portion indicated by the center line β of each of the left and right heating means 34 and 35 is a distance E357 mm (E = B / 2) from the center portion of the top plate 22 indicated by the center line α to the left and right end portions. It is located at a distance F (165 mm), and is located approximately 46% from the center in the ratio. As described above, the fact that the central portion of each heating means 34, 35 is located at a position of 46% from the central portion means that the heating means 34, 35 is disposed in a range of less than 50%. 35 indicates that each center portion is located closer to the center while securing a predetermined interval dimension T30 mm, and therefore a sufficient distance is provided at the left and right ends even when a pan having the maximum pan diameter K is placed. Can be secured. However, the distance F to the center is preferably 150 to 170 mm (42 to 48%) including the present embodiment, but can be less than 50%.

  In the present embodiment, the depth dimension G of the top plate 22 is 406 mm, whereas the distance H from the center of the heating units 28 and 29 arranged on the left and right to the front end is 182 mm. Therefore, the heating means 34 and 35 are also arranged slightly forward, and the installation space for the heating part 30 and the heating means 36 at the back of the center is effectively secured, while the maximum pan diameter K (the same diameter as the heating parts 28 and 29). In the shortest distance J from the outer shell of the pan of Fig. 2) to the front end, 32 mm is secured, which is longer than the predetermined interval T, and a sufficient margin is secured in the direction of the front end. ing.

Next, the operation of the cooking device having the above configuration will be described.
First, in order to incorporate in the kitchen 41, as shown in FIG. 3, the width Y of the case body 21 with respect to the drop hole 42 (width Z) of the countertop 41 has the same numerical relationship (Y <Z) as in the prior art. Therefore, it can be easily incorporated into the kitchen 41 by drop-in without any problem.

  On the other hand, when placing a pan on the top plate 22 for cooking, the horizontal dimension B of the top plate 22 is increased to 714 mm, and at least the left and right heating units 28 and 29 are juxtaposed. At the time, the center of each of the left and right heating means 34, 35 is secured from the center to the left and right ends of the top plate 22 after securing a space dimension W (30 mm) at which the pan and the handle on the center are not in contact. The distance F is set to be less than 50% (about 48% in the embodiment). As shown by the center line β, this center portion is in a relationship that coincides with the center of each heating unit 28, 29 and the pan placed thereon.

  Thus, the pan placed on the central portion and obtained the maximum allowable pan diameter K (300 mm) is juxtaposed near the center portion of the top plate 22 through a predetermined interval T30 mm, and A sufficient distance D from the outer shell to the left and right ends of the top plate 22 can be secured (D> T). Thereby, even when the pan is juxtaposed with the left and right heating units 28 and 29, the pan can be placed under an arrangement condition sufficiently separated from the periphery in any of the left and right directions, and the maximum pan diameter allowed for actual use. K can be set.

As described above, the present embodiment has the following effects.
In the above-described drop-in type cooking device, the installation work by dropping the case main body 21 incorporating the roaster 26 and the like into the limited space of the industry standard with respect to the counter top 42 is performed under the same condition setting as before. In addition, the width B of the top plate 22 can be increased to increase the diameter of the pan that can be placed on the top plate 22, that is, the so-called cooking pan that can be used for cooking. Many pots can be used for cooking, and usability can be improved.

  Moreover, in the pan juxtaposed on the left and right heating units 28 and 29, for each pan having the maximum pan diameter K obtained on condition that the predetermined interval T (30 mm) can be secured, the left end portion of the top plate 22 and The heating means 34, the distance D (42 mm) to the right end is set longer than the predetermined interval T, or the distance E (357 mm) from the center of the top plate 22 to the left and right ends By setting the central portion of 35 within the range of less than 50% (about 48% indicated by the distance F) from the central portion, that is, closer to the central portion, the pot diameter K can be increased by 300 mm, and the left and right ends It is possible to sufficiently suppress the pan from protruding from the section.

  Therefore, the pan does not come into contact with each other or the handle on the center side, and contact with other articles installed on the side can be avoided at the left and right ends. It can also be avoided that the article is inadvertently heated or the handleability is deteriorated due to the difficulty of grasping the handle of the pan. In addition, it is convenient to prevent spills and splashes from the pan from falling on other parts in the vicinity.

  In particular, in the drop-in type, since the top plate 22 and the counter top 42 are devised so as to be as flush as possible, problems such as erroneous heating of other cooking utensils and the like can be considered. The distance margin at the left and right end portions of the heating device 34 and 35 is sufficiently separated from the left and right end portions, and it is possible to effectively prevent the cooking utensils etc. from being directly heated, which is safer and easier to use. Can provide a good cooker.

  The present invention is not limited to the embodiment described above and shown in the drawings. For example, if the width dimension B of the top plate is 700 mm or more, the distance D is equal to or greater than the predetermined interval T in the central portion and the interval T in the left and right end portions. In addition to the three-port type, it is sufficient to use a two-port type in which heating units are arranged at least on the left and right sides. Various modifications can be made without departing from the scope of the present invention, such as a halogen lamp or a sheathed heater.
