Description

  The present invention relates to a heating cooker that heats a heated cooking container placed on a top plate.

  In general, in this type of cooking device, a radial heater such as an induction heating coil or an electric coil is provided as a heating means in a box-shaped case body, and is placed on a top plate disposed on the opposite upper surface side. The heated cooking container is heated. This heating cooker is assembled by being dropped onto a top plate such as a system kitchen, and the top plate is maintained in a state of protruding on the top plate. This is a so-called drop-in method, and is a means for incorporating the case body from above into an opening formed in the top plate. However, the top plate made of crystallized glass, which is usually made of heat-resistant glass, is not easy to process. It is covered with a frame and fixed with adhesive. In particular, the frame-shaped frame that covers the outer peripheral edge is supported by abutting the opening peripheral edge of the top plate when the heating cooker is dropped into the kitchen top plate, or the appearance of the peripheral edge of the top plate (See Patent Documents 1 and 2, for example).

  However, mounting the frame of the separate member as described above on the outer peripheral edge not only has the problem of increasing the number of assembling steps, but also has a difficult appearance design, and also occurs on the top plate upper surface and the edge portion of the frame. If the stepped portion is contaminated with dirt or the like, or if the degree of adhesion is poor, it cannot easily be cleaned by entering from the gap. In many cases, the frame is made of metal. In this case, however, there is a concern that safety must be sufficiently considered so as not to be injured at the edge portion.

  Therefore, as a countermeasure, there has been proposed a configuration in which the frame-shaped frame is removed, that is, a configuration in which the outer peripheral edge portion is integrally formed with only a top plate made of heat-resistant glass as a frameless. FIG. 7 is an enlarged cross-sectional view of the main part showing an example, and the case main body 2 of the cooking device 1 is dropped from the opening 3 a of the kitchen top plate 3, and the flange portion 2 a is the opening edge of the top plate 3. The structure by which it was hooked and supported on the upper surface of the part is shown, and the heating cooker 1 whole is integrated in the top plate 3, and is supported. Reference numeral 4 denotes a reinforcing plate. An upper horizontal support portion 4a, which is one end of the reinforcing plate, is attached to the back surface of the outer peripheral edge portion of the top plate 5 and joined by an adhesive 8, and the hanging portion 4b at the other end is a case body. 2 is fixedly connected.

Thus, the support 4a of the reinforcing plate 4 is joined and fixed by the top plate 5 and the adhesive 6, and the top plate 5 and the case body 2 are integrated, that is, a so-called heating cooker 1 is configured. . Further, a packing 7 is mounted in a pressure-bonded state between the back surface of the top plate 5 and the top surface of the top plate 3, and has a water sealing function to prevent intrusion of water or the like. As described above, the outer peripheral edge of the top plate 5 is vertically overlapped with the opening peripheral edge of the top plate 3, and includes the flange portion 2a supporting almost the entire weight therebetween, the support portion 4a of the reinforcing plate 4, In addition, since the packing 7 is interposed, these arrangement locations require an overlapping range with a considerable width, and require a gap α2 in the height direction.
Japanese Patent No. 3054836 Japanese Patent Laying-Open No. 2005-83639

  Thus, according to the frameless configuration, problems such as contamination due to the frame can be solved, but the gap α2 is particularly large, which means that the top plate 5 is lifted higher than the top plate 3 (high Dimension T2). Therefore, it is not easy to use in the kitchen, such as making various cooking containers collide with the stepped part of the top plate 3 generated at the peripheral edge, and losing the contents of the pan etc. It is not preferable as a design.

  In order to solve the above-mentioned problems, the present invention has good usability without reducing the water sealing function and built-in workability while reducing the gap in the overlapping portion of the top plate and the top plate, and preferable heating as an external design. The purpose is to provide a cooker.

In order to achieve the above object, a heating cooker of the present invention comprises a case main body provided with heating means, and a top plate that is provided so as to cover the upper surface of the case main body and on which a cooked cooking container is placed, The top plate is integrally formed of heat resistant glass or ceramic,
The case main body is housed inside by dropping from an opening of a top plate of a kitchen or the like, and an outer peripheral edge of the top plate overlaps with an opening edge of the top plate. A concave portion is formed on the inner back surface excluding the peripheral edge portion of the overlapping outer peripheral edge portion, and one end of the reinforcing plate connected to the case main body side is fixed to the concave portion, and the concave portion The main feature is that a packing that seals water between the top plate and the top plate is mounted.

    According to the above means, the top plate can be constructed framelessly, can cope with dirt and can be maintained beautifully, and the reinforcing plate and packing can be accommodated in the recesses on the back surface of the top plate, thereby reducing the gap between them. However, it is possible to provide a cooking device that can be incorporated without any problems in terms of water sealing effect and strength, and therefore has a low height of the top plate and is easy to use and has a good appearance design.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
2 is an external perspective view of a state where the cooking device 11 is incorporated in the top plate 12 of the system kitchen, for example, FIG. 3 is a longitudinal side view thereof, and FIG. 4 is a plan view thereof. The overall configuration will be briefly described. The cooking device 11 comprises a rectangular box-shaped case main body 13 having an open upper surface and a top plate 14 mounted on the upper surface, and the case main body 13 portion is formed on the top plate 12 of the kitchen. It is dropped from the opening 12a (see FIG. 3) and supported by the opening peripheral edge of the top plate 12 on the back surface side of the top plate 14 (details will be described later). The case body 13 is provided with heating means and air cooling means, which will be described later, and an operation panel portion 15 is provided on the right side of the front surface as shown in FIG. A roaster device 16 including a display heater and a sheathed heater (not shown) is provided on the left side.

  On the other hand, the top plate 14 constituting the upper surface of the heating cooker 11 is integrally formed in a flat rectangular plate shape made of, for example, transparent tempered heat resistant glass (crystallized glass). The heating units 18, 19, and 20 that indicate the placement unit that is suitable for heating the cooked container such as the pan 17 are printed and displayed at three locations indicated by the circular frame lines. Among them, the heating parts 18 and 19 at two places on the front left and right can heat the pot 17 as a cooking container based on the induction heating coils 21 and 22 which is one of heating means provided in the case body 13. Moreover, the heating part 20 located in the back center is arrange | positioned with the radial heater 23 which consists of a nichrome wire, for example, can heat to-be-heated cooking containers, such as the pan 17, and forms what is called a three-necked stove.

  However, the upper surface of the top plate 14 having the three heating portions 18, 19, and 20 on which the cooked cooking container is placed is formed on a flat surface except for an area having an intake / exhaust portion (described later) behind it. In addition to the heating units 18, 19, and 20, the pan 17 and the like are set as a mounting surface. Further, output display units 18a, 19a, and 20a are provided in front of the heating units 18, 19, and 20, and output (thermal power) display in response to a dial operation of the operation panel unit 15 is possible although details are omitted. This makes output adjustment easy. In the rear part of the top plate 14, horizontally long slots 24 and 25 are formed in two places on the left and right sides, and a porous plate-like cover member 26 is detachably attached so as to cover these upper surfaces. ing. However, the long holes 24 and 25 are for sucking and exhausting air through the inside and outside of the case body 13, and the cover member 26 is positioned by using a slight stepped portion around and is detachably mounted. .

  In the cross-sectional view of FIG. 3, the heating means facing the right heating unit 18 among the heating units 18, 19, 20 provided on the top surface of the top plate 14 in the case body 13, that is, the induction heating coil 21. A configuration in which is disposed via a coil support member 27 is shown. However, the space below these heating means is equipped with means for driving and controlling the heating means, and an inverter board and a microcomputer constituting the inverter 28 for supplying high-frequency current to the induction heating coils 21 and 22. Built-in control circuit board and the like. The inverter 28 as the driving means is configured to include a heat-generating switching element such as an IGBT constituting the main circuit, and induction heating is performed by the driving means and the induction heating coils 21 and 22. Configure the device.

  Therefore, the induction heating apparatus is provided with a heat-generating switching element such as the inverter 28 and the air cooling means for cooling the induction heating coils 21 and 22. As this air cooling means, a blower 29 comprising a blower fan 29a, a motor 29b and the like is provided, and performs a cooling action by a blower action for taking in outside air. For this reason, the necessary intake / exhaust is performed using the long holes 24 and 25 described above. It should be noted that simple shapes such as the long holes 24 and 25 can be drilled at a stage where the tempered heat-resistant glass is heat-molded and still workable before crystallization.

  As shown in FIGS. 3 and 4, the air blowing action is provided on the intake side of the air blower 29 with an intake duct 30 for sucking outside air facing the elongated hole 24, while the air blower 29 discharges the air. The downstream side, which is the side, is blown with the internal space having the inverter 28 of the case main body 13 as a closed space, and the exhaust air is provided so that a part of the case main body 13 directly faces the elongated hole 25 and can be discharged to the outside. Yes. Note that a part of the air flow is guided also to the induction heating coils 21 and 22 side, and the temperature rise of the heat generating parts is suppressed by the cooling action by the air flow in the direction of arrow A in the figure.

  Further, in FIG. 4, the roaster device 16 provided on the inner left side of the case main body 13 is provided with an independent exhaust means for discharging smoke generated by cooking. That is, although the details are omitted, it is partitioned separately from the closed space of the inverter 28 and the like, and forms another closed space that covers the roaster device 16, and the exhaust duct 31 communicating with the closed space is connected to the long hole on the left side. No. 25 is arranged at a position facing it, and smoke generated during cooking of the pottery or the like can be naturally exhausted in the direction of arrow B to the outside. The intake action in this case is drawn from an appropriate gap on the front side of the roaster device 16. Thus, both the exhaust after cooling of the induction heating device and the exhaust such as smoke from the roaster device 16 can be discharged from the long hole 25 on the left side of the top plate 14.

  Here, the built-in configuration by dropping the case body 13 onto the top plate 12 will be described mainly with reference to FIG. FIG. 1 is an enlarged cross-sectional view taken along the line XX in FIG. 4, and the outer peripheral flange portion 32 (not necessarily continuous over the entire periphery) of the main body case 13 is an opening portion of the top plate 12. 12a shows a configuration that is hooked on the peripheral upper surface and receives the load of the case main body 13. Thus, the heating cooker 11 is supported on the top plate 12. However, the case body 13 and the top plate 14 are connected and integrated through a metal reinforcing plate 33 having a rectangular frame shape as a whole.

  The reinforcing plate 33 has a frame shape in which the outer shape is slightly smaller than that of the top plate 14 and the inside is opened into a large rectangular shape. That is, as shown in FIG. 4, at least the three heating means described above are open without covering them. In this embodiment, the flat horizontal surface of the frame-like outer peripheral upper surface is used as the support portion 33a, the plurality of hanging portions 33b vertically bent downward, and the bent base portion is slightly recessed from the horizontal surface. The shape has a recessed step portion 33c. Thus, the drooping portion 33b is fixed to the case body 13 with a screw 34, and the horizontal support portion 33a is bonded to the back surface of the top plate 14 with an adhesive 35 filled in the concave step portion 33c. Thus, the top plate 14 and the case main body 13 are integrated. Although not described in detail, the rear portion of the reinforcing plate 33 has a shape having an opening so as not to obstruct at least the suction and exhaust ducts 30 and 31.

  By the way, the back surface of the top plate 14 to which the support portion 33a is addressed forms a rectangular recess 36 in a wide inward range excluding the peripheral end portion. Moreover, a packing 37 is bonded and fixed to the top plate 14 side with an adhesive at a position along the lower surface of the outer peripheral edge of the support portion 33a and the inner peripheral side of the recess 36. However, in FIG. 1 showing the assembled state, when the flange portion 32 is supported in a hooked state on the top plate 12, the packing 37 is held in a slightly compressed state, and the outer peripheral edge portion of the top plate 14 and the top plate are held. The water sealing action prevents water from entering through the slight gap α1 generated between the first and second gaps. The gap α1 is necessary to prevent the back surface of the top plate 14 from coming into contact with the top plate 12 so as to receive a load at the flange portion 32 as described above. For example, the clearance α1 is 0.5 to 1.0 mm. The gap size is small. This is made as small as possible to keep the height dimension T1 from the top surface of the top plate 12 to the outer surface of the top plate 14 small.

  In contrast to the configuration on the back surface side, on the surface side of the peripheral end portion of the top plate 14, an inclined surface portion 38 that is inclined downward toward the peripheral end portion is formed on the entire periphery. A width dimension h1 of a so-called non-recessed portion extending from the peripheral end portion on the back surface side to the recessed portion 36 is set to be equal to or larger than the width dimension H1 from the circumferential end portion provided with the inclined surface portion 38 (width). Dimensions H1 ≦ h1). In the embodiment shown in FIG. 1, the width dimension H <b> 1 <h <b> 1 is shown, and the so-called inclined surface portion 38 (width dimension H <b> 1) is arranged so as not to face the recess 36 on the back surface side.

Next, the operation of the heating cooker 11 having the above configuration will be described.
First, the procedure for assembling into the top plate 12 will be described with reference to FIG. 1 in particular. As described above, the top plate 14 fills the concave step portion 33c with the support portion 33a of the reinforcing plate 33 in the concave portion 36 on the back surface. It joins with the adhesive agent 35, and it is joined to the recessed part 36 with the adhesive agent so that the packing 37 may overlap with the support part 33a. The drooping portion 33b of the reinforcing plate 33 is coupled to the case main body 13 provided with heating means, the blower 29, and the like by screws 34, so that the top plate 14 is connected to the case main body 13 at a predetermined position. The cooking device 11 is configured by being fixed and integrated.

  The heating cooker 11 is dropped (dropped) from above into the opening 12a of the top plate 12 from the case main body 13 side, and the flange portion 32 at the upper end of the case main body 13 is hooked on the opening periphery of the top plate 12 to be supported. At this time, the packing 37 is compressed and pressed onto the top plate 12, and a slight gap α1 is ensured. Therefore, the flange portion 32 supports the load, the packing 37 is pressure-bonded to the top plate 12 to form a water sealing function, and the top plate 14 has no load load and is joined to the lower surface of the outer peripheral edge portion. The mechanical strength is increased by the plate 33 (support portion 33a).

  On the other hand, the cooking operation by the cooking device 11 is well known, and will be briefly described below. Of the heating means, for example, the induction heating coil 21 on the right side of the heating means is driven via a driving means such as an inverter 28 by a dial operation on the operation panel 15, and the pot 17 placed on the heating part 18 of the top plate 14 is driven. For example, boiled food cooking is started. In this case, the heating output is set following the selection operation of the heating means, the light emission display by the LED (not shown) is made on the output display portion 18a, and the desired output state is set while visually confirming the lighting number.

  And with the start of the said heating cooking, the air blower 29 which comprises an air-cooling means is also driven, and as shown in FIG.3, 4, the external air taken in from the intake duct 30 is ventilated in the arrow A direction. Then, the air is exhausted from the long hole 25 side through a closed space in which the inverter 28 having a heat-generating switching element, the induction heating coil 21 and the like are air-cooled. On the other hand, when the roaster device 16 is used to cook a grilled fish such as fish, the warm smoke generated at that time passes through the closed space separated from the above by the convection action, and the direction of the arrow B And is naturally exhausted from the rear exhaust duct 31 and the opening 25 to the outside.

  In such practical use, boiled juice or the like is blown over the top plate 14 during cooking, or water used in the kitchen is scattered. However, in the present embodiment, the placement surface, which is the upper surface of the top plate 14 having the heating portions 18, 19, and 20 on which the pan 17 and the like are placed, is formed as an integral body that is not equipped with a frame or the like of another member. Therefore, dirt can be easily wiped clean, there is no trouble such as dirt collecting or soaking in the frame edge part and it can be kept beautiful and clean, and the overall appearance is also good design with beautiful glass material be able to.

  Further, as shown in an enlarged view in FIG. 1, the surface side of the entire outer peripheral edge portion of the top plate 14 is formed with an inclined surface portion 38 that is inclined downward toward the outer peripheral edge portion (so-called bevel processing). ). This is because the so-called right-angled corners are cut and gradually descended and tilted, so that collisions are reduced particularly when handling a heated cooking container such as the pan 17, and even if a collision occurs, the shock is caused by the tilt angle. It has the effect of mitigating (impact), so that the broth in the pan 17 can be kept from being lost as much as possible, and thus safe handling is possible.

  However, as described above, a frameless configuration is provided in which no other member such as a frame is provided at the peripheral end portion, so that an inclined surface portion 38 that is thinner toward the peripheral end portion is formed, and further, a concave portion 36 is provided on the back surface side. This has a concern that the mechanical strength at the outer peripheral edge of the top plate 14 made of heat-resistant glass is weakened and easily damaged. However, in this embodiment, the width dimension h1 from the peripheral edge on the back surface side to the recess 36 is set equal to or greater than the width dimension H1 of the inclined surface portion 38 (width dimension H1 ≦ h1). ), The concave portion 36 and the inclined surface portion 38 do not overlap in the vertical direction, so that the outer peripheral edge portion can be prevented from being thinned and the strength can be prevented from being lowered. In addition to the function of the inclined surface portion 38, for example, It is effective in protecting against damage when dropping objects from above.

As described above, the present embodiment has the following effects.
The top plate 14 made of heat-resistant glass is integrated with at least the outer periphery of the mounting surface including the heating units 18, 19, and 20 on which the pan 17 and the like are mounted without attaching a separate frame or the like as in the conventional configuration. Since it is configured, even if boiling water spills during cooking, or water used in the kitchen scatters, there is no problem such as accumulation or smearing on the edge of the frame, and easy cleaning It can be kept beautiful and clean at all times, and the overall appearance can be made of a beautiful glass material. In addition, it is possible to reduce the number of parts such as a frame and the number of assembling steps, and in particular, it is possible to avoid the troublesome work burden of joining other members with high accuracy, so that the assembling workability can be improved and the manufacturing cost can be expected to be reduced.

  The rectangular frame-shaped reinforcing plate 33 that connects the top plate 14 and the case main body 13 is joined to the top surface of the top plate 14 with an adhesive 35 that is attached to the back surface of the top plate 14 by bonding the support portion 33a. The plate 14 is reinforced. However, the case main body 13 is mounted by being dropped into the top plate 12, and the opening edge portion of the top plate 12 and the outer peripheral edge portion of the top plate 14 are overlapped with each other, and the support portion 33a is interposed therebetween. And a flange portion 32 that supports a load, a packing 37 that performs water sealing, and the like. Therefore, in this embodiment, the recessed portion 36 that is recessed on the back surface side excluding the peripheral end portion of the top plate 14 is formed. The recessed portion 36 overlaps with the opening edge of the top plate 12 and is formed at a portion located inwardly by the width dimension h1 (see FIG. 1) from the outer peripheral end of the top plate 14.

  As a result, the support portion 33a and the packing 37 are mounted in the recess 36, and the gap α1 at the outer peripheral end can be made as small as possible as compared with the conventional configuration that does not employ the frame shown in FIG. This means that the height dimension T1 protruding on the top plate 12 can be substantially suppressed to the thickness of the top plate 14, and the stepped portion can be suppressed small. As a result, not only the appearance design is improved, but also it is difficult for objects to enter from the minute gap α1, and especially when handling various cooking containers such as the pan 17, the fear of colliding with the stepped portion can be reduced. It can be prevented from getting dirty and contaminated, and it is easy to use including safety.

  In addition, since the recess 36 is formed excluding the peripheral end portion (corresponding to the width dimension h1) of the top plate 14, the outer peripheral edge portion is thick and effective in preventing damage to the outer peripheral edge portion such as the pan 17 that is likely to collide. It is. In addition, in the present embodiment, the inclined surface portion 38 is formed on the surface side, the appearance design is further improved, and the shock due to the collision of the pan 17 or the like is softened, but with respect to the width dimension H1 of the inclined surface portion 38, Since the width dimension h1 of the outer peripheral edge where the concave portion 36 is not formed is set to be equal to or larger than that, it is possible to avoid the reduction of the strength of the outer peripheral edge by avoiding the thinning of the inclined surface portion 38. .

FIG. 5 and FIG. 6 are diagrams corresponding to FIG. 1 showing a modification of the above embodiment. The same reference numerals are given to substantially the same parts as those in the above embodiment, and the description thereof will be omitted.
First, the modification shown in FIG. 5 is suitable when the overlapping dimension C of the top plate 14 and the top plate 12 can be adopted larger than that of the above embodiment. That is, in the above-described embodiment, the support portion 33a and the packing 37 are mounted in the recessed portion 36 so as to overlap vertically, whereas in this modified example, they are separately housed in the recessed portion 36.

Accordingly, the support portion 39a and the hanging portion 39b as the reinforcing plate 39 have substantially the same configuration as the above embodiment, but the filling portion of the adhesive 35 formed on the support portion 39a is a groove-shaped concave step portion 40. It is different in point.
In this case, the packing 37 and the support portion 39a can be joined independently, and there is an advantage that workability is improved.

Next, the modification shown in FIG. 6 is different in that the recess 42 formed on the back surface of the top plate 41 is formed in a groove shape. That is, for example, a rectangular continuous groove portion is formed in the outer peripheral edge portion on the back surface side of the top plate 41, and the groove portion is used as the concave portion 42.
In this case, it is suitable for the case where it is desired to secure a thickness to increase the strength of the mounting surface such as the heated cooking container of the top plate 41 with respect to the embodiment.

  The present invention is not limited to the embodiment described above and shown in the drawings. For example, the intake / exhaust area having a long hole for intake or exhaust provided in the rear portion of the top plate is configured by a member different from the top plate. You may do it. Further, the top plate may be made of ceramic, and the type (function) or number of heating means may be changed as appropriate, such as heating means, and various changes may be made without departing from the scope of the present invention. .
