DESCRIPTION OF EMBODIMENTS Hereinafter, a preferred embodiment of a cooking system according to the present invention will be described with reference to the accompanying drawings.
Embodiment 1 FIG.
1 is a cross-sectional view illustrating a configuration of a cooking system according to Embodiment 1. FIG. As shown in FIG. 1, the cooking system according to the present embodiment includes a cooking device 10 and a worktop 20 in which the cooking device 10 is incorporated. And the heating cooker 10 is accommodated in the housing | casing 11, the box-shaped housing | casing 11 of upper openness, the L-shaped main body flange 11a which protruded outside from the upper end part of the housing | casing 11, and it is in one plane. A pair of heating coils 12 wound in a spiral shape, and a detachable flat top plate 13 that is disposed in proximity to the upper side of these heating coils 12 and is in contact with the upper surface of the main body flange 11a. A drive circuit 14 that increases or decreases the amount of high-frequency alternating current flowing through the heating coil 12, and an operation / display unit 15 that inputs a signal such as a heating / stop signal to the drive circuit 14 or a temperature setting of an object to be heated; It has.

  Here, a transparent heat-resistant insulating material such as crystallized glass is used for the top plate 13. In addition, a pan (heating container) 30 in which an object to be heated is accommodated can be placed on the top surface of the top plate 13 at a position facing the heating coil 12. The pan 30 is generally made of a metal material such as iron, and the pan 30 is placed in an alternating magnetic field formed around the coil as the heating coil 12 is energized by an instruction from the operation / display unit 15. It becomes. As a result, due to the action of the eddy current flowing inside the pot 30, the entire pot 30 becomes a heating source, and the object to be heated accommodated in the pot 30 is heated.

  On the other hand, the work top 20 includes an opening 21 in which the heating cooker 10 is incorporated, and a top flange 20 a having an L-shaped cross section formed on the periphery of the opening 21. The casing 11 and the top plate 13 of the heating cooker 10 are inserted into the opening 21 from above, and the end portions of the main body flange 11a and the top plate 13 are in contact with and supported by the top flange 20a. Here, by forming the distance between the upper surface of the work top 20 and the upper surface of the main body flange 11a substantially the same as the plate thickness of the top plate 13, the upper surface of the work top 20 and the upper surface of the top plate 13 can be made substantially flush with each other. A flat configuration is possible.

  As shown in the partial sectional view of FIG. 2, spacers 16 are inserted into the gap between the top plate 13 and the main body flange 11a and the gap between the main body flange 11a and the top flange 20a, respectively. An I-shaped portion of the frame body 22 having a substantially T-shaped cross section is inserted into at least one side of the boundary between the end surface of the top plate 13 and the worktop 20. A claw portion 22 a is provided on the side surface of the I-shaped portion, and the top plate 13 is fixed to the work top 20 by fitting the claw portion 22 a into the work top 20 and the top plate 13 during insertion.

  In the present embodiment, the fixing method using the claw portion 22a is used. However, pressure fixing by a spring body, adhesion fixing by a sealing material, or the like may be used. Further, since the frame body 22 is composed of an integrally molded product such as resin, the color and the like can be freely selected. Furthermore, by setting the thickness of the head portion of the frame body 22 to 5 mm or less, a full flat surface with less protruding feeling can be configured.

  According to FIGS. 1 and 2, the top plate 13 and the work top 20 are arranged on substantially the same plane. Further, a frame body 22 having a head portion thickness of 5 mm or less is inserted into the peripheral surface of the top plate 13. Therefore, a smooth stop with excellent operability and design can be realized.

  Specifically, in the installation work, the heating cooker 10 is inserted into the opening 21 of the work top 20, and the main body flange 11 a is stopped and fixed on the top flange 20 a via the spacer 16. Next, the top plate 13 is inserted into the opening 21 of the work top 20, and the top plate 13 is brought into close contact with the main body flange 11 a via the spacer 16 to be internally provided. Furthermore, the installation work is completed by inserting the frame body 22 having a desired color in accordance with the design into the gap between the end faces of the top plate 13 and fixing the top plate 13 to the work top 20. By removing the frame body 22 and opening the top plate 13 during maintenance, the inside of the heating cooker 10 can be easily inspected.

  In the cooking system of the present embodiment, the work top 20 and the top plate 13 have substantially the same plane, and only the head portion of the frame body 22 protrudes from this plane. For this reason, when the pan 30 is moved from the inside of the top plate 13 (or from the outside to the inside), it is not necessary to raise or lower the pan 30 and the pan 30 can be moved smoothly. Furthermore, even when the object to be heated is blown down from the pan 30, the frame body 22 becomes a breakwater, and it is possible to prevent liquid or the like due to blown down from entering the inside of the casing 11 or the work top 20.

As described above, according to the present embodiment, a smooth stop excellent in design and operability is realized. In addition, by inserting the frame body 22 at the boundary between the opening 21 of the work top 20 and the top plate 13, reliable fixing of the top plate 13 and prevention of liquid leakage into the housing 11 are realized at the same time. Cleanliness is improved. Furthermore, since the top plate 13 can be easily attached and detached at the time of installing the heating cooker 10 on the work top 20 or during maintenance, it is possible to obtain an excellent effect that the time required for construction and maintenance can be greatly reduced.
If the work top 20 and the top plate 13 cannot be kept on the same surface, the height of the top plate 13 can be adjusted by changing the thickness of the spacer 16 provided on the contact surface between the top flange 20a and the main body flange 11a. Therefore, a smooth stop with substantially the same surface is surely realized.

Embodiment 2. FIG.
Next, the heat cooking system which concerns on Embodiment 2 is demonstrated. FIG. 3 is a partial cross-sectional view showing the cooking system according to the second embodiment. In addition, the same code | symbol is attached | subjected about the component which is the same as that of Embodiment 1, or equivalent, and the description is abbreviate | omitted.

  As shown in FIG. 3, the main body flange 40 is provided in a two-step shape, and an L-shaped first flange 40 a projecting outward from the upper end portion of the housing 11, and an outer side from the upper end portion of the first flange 40 a. And a second flange 40b projecting over. On the other hand, the work top 20 does not include the top flange 20a having an L-shaped cross section as shown in the first embodiment, and the opening 21 has a normal flat end surface.

  The housing 11 of the heating cooker 10 is inserted into the opening 21 from above, and the second flange 40 b is brought into contact with and supported by the upper surface of the worktop 20 via the spacer 16. The housing 11 is incorporated in the 21. Next, the top plate 13 is brought into close contact with the upper surface of the first flange 40a via the spacer 16, and the interior is installed. At this time, by forming the distance between the first flange 40a and the second flange 40b substantially the same as the plate thickness of the top plate 13, the upper surface of the second flange 40b and the upper surface of the top plate 13 are made substantially the same surface. And a fully flat configuration is possible. However, although the top plate 13 protrudes by the thickness of the second flange 40b with respect to the upper surface of the work top 20, when viewed as a whole, the top plate 13 is sufficiently flat.

  An I-shaped portion of the frame body 22 having a substantially T-shaped cross section is inserted into at least one side of the boundary between the end surface of the top plate 13 and the second flange 40 b, and the top plate 13 is fixed to the worktop 20. . Further, the T-shaped head portion of the frame body 22 extends in the lateral direction to form a cover body 22b that covers the entire second flange 40b.

As shown in FIG. 3, the top plate 13 and the worktop 20 are arranged on substantially the same plane. Further, the frame body 22 is provided with a cover body 22b for holding the second flange 40b so that the second flange 40b is not directly visible.
As a result, a substantially full flat can be formed without the troublesome process of forming the top flange 20a having an L-shaped cross section in the opening 21 of the work top 20. In addition, a smooth stop with excellent design and operability can be realized. Furthermore, liquid leakage into the housing 11 is suppressed, and cleanliness is improved. Furthermore, since the top plate 13 can be easily attached and detached at the time of installing the heating cooker 10 to the work top 20 or during maintenance, an excellent effect can be obtained such that the time required for construction and maintenance can be greatly reduced.

As shown in FIG. 4, the top plate 13 has an outer peripheral end face fitted in close contact with the end face of the opening 21 of the work top 20, and a convex projection frame 13 a extending upward is integrated with the end portion of the top plate 13. Is provided. For this reason, even when liquid or the like flows out onto the top plate 13 due to spilling of the object to be heated, the projection frame 13a serves as a breakwater and can prevent outflow to the work top 20. Therefore, the liquid can be prevented from entering the housing 11 without securing the watertightness between the end surface of the top plate 13 and the end surface 21 of the opening 21 of the worktop 20, and the frame-less design is excellent. A cooking system can be obtained.
The protrusion 13a is ideally molded integrally with the top plate 13, but a separate body may be attached. Further, a sealing material or the like may be inserted into a contact portion between the end surface of the top plate 13 and the end surface of the opening 21 of the work top 20.

A packing material 41 is attached to the concave slit 13b, and the top plate 13 and the work top 20 are closely attached.

  For this reason, even when liquid or the like flows out onto the top plate 13, the packing material 41 prevents the inflow into the housing 11. Therefore, the rough opening 21 can be configured without matching the depth of the top surface of the work top 20 and the top flange 20a with the thickness of the top plate 13 or paying attention to the end face processing of the opening 21. With this, sufficient sealing performance can be secured. Further, only the thickness of the top plate 13 protrudes from the work top 20, so that a cooking system having a substantially smooth stop and frameless design can be obtained.

  FIG. 6 is a cross-sectional view showing a modification of the cooking system according to the fourth embodiment. In addition to the configuration of FIG. 5, the heating cooking system of FIG. 6 is provided with a work top slit (second positioning groove) 20 b on the upper surface of the work top 20 positioned facing the concave slit 13 b of the top plate 13.

With this configuration, even when liquid or the like flows out onto the top plate 13 due to the spill of the object to be heated, the projection frame 13a serves as a breakwater and can prevent the liquid or the like from flowing out to the work top 20. Accordingly, it is possible to prevent a liquid or the like from entering the worktop 20 and to obtain a cooking system that is excellent in design without a frame.

Embodiment 5 FIG.
Next, the heating cooking system which concerns on Embodiment 5 is demonstrated. FIG. 8 is a partial cross-sectional view showing the heat cooking system according to the fifth embodiment. The fifth embodiment is different from the fourth embodiment shown in FIG. 5 in that a convex partition projection 13c extending upward from the end of the top plate 13 with a predetermined distance is molded integrally with the top plate 13. And the point where the operation / display unit 42 is disposed in the space forming the predetermined distance. Other configurations are the same as or equivalent to those in FIG. 5 of the fourth embodiment. In addition, the same code | symbol is attached | subjected about the component which is the same as that of Embodiment 4, or the description, and the description is abbreviate | omitted.

  As shown in FIG. 8, the operation / display unit 42 is configured by a switch unit 43 configured by a plurality of reflective photointerrupters that transmit the top plate 13 and a plurality of LEDs that transmit the top plate 13. And a display unit 44. The operation of the switch unit 43 according to the present embodiment is such that when the user selects a switch, the light emitted from the light emitting element is emitted by the finger when the user holds the finger or the like over a target reflective photointerrupter at a predetermined distance. It functions as a switch by being reflected and received by the light receiving element. In the present embodiment, the operation / display unit 42 is configured integrally with the top plate 13, but an operation / display substrate may be arranged on a space having a predetermined distance to provide another configuration. The switch unit 43 may be an element such as a contacted switch using electrostatic capacity.

  Here, a partition projection 13c is provided on the top surface of the top plate 13, and one of the partition projections 13c is divided into an operation / display section 42 and the other is divided into a heating section space. For this reason, even when liquid or the like flows out onto the top plate 13 due to spilling of the object to be heated, the partition projection 13c becomes a breakwater, and it is possible to prevent liquid or the like from spilling in the operation / display unit 42. In addition, when the pan 30 having a high pan bottom temperature is moved by heating, even when the operation / display unit 42 is approached, the partition projection 13c serves as a guard and the pan 30 touches the operation / display unit 42. Can be prevented and safety is improved. Furthermore, it is possible to obtain a cooking system including the top plate 13 having an excellent design with the operation / display unit 42 integrated.

Embodiment 6 FIG.
Next, a heat cooking system according to Embodiment 6 will be described. FIG. 9 is a partial cross-sectional view showing the heat cooking system according to the sixth embodiment. The sixth embodiment is different from the fourth embodiment shown in FIG. 5 in that the main body flange 11a of the housing 11 is in direct contact with the upper surface of the work top 20, and the end of the top plate 13 is downward. It is the point which extends and comprises the leg part 13d. Other configurations are the same as or equivalent to those of the fourth embodiment. In addition, the same code | symbol is attached | subjected about the component which is the same as that of Embodiment 4, or the description, and the description is abbreviate | omitted.

  As shown in FIG. 9, the work top 20 is not provided with a top flange 20 a, and the housing 11 inserted into the opening 21 of the work top 20 has a body flange 11 a directly against the upper surface of the work top 20. It is held in contact. Further, the end portion of the top plate 13 extends downward, and a leg portion 13 d having a height equal to or greater than the plate thickness of the main body flange 11 a is formed integrally with the top plate 13. And the leg part 13d is mounted | worn on the surface of the worktop 20 in the state which covered the main body flange 11a from upper direction. For this reason, the top plate 13 covers the main body flange 11a from above, and the main body flange 11a is not directly visible.

  As a result, without the cumbersome process of forming an L-shaped cross section at the end of the work top 20, the approximate amount protruding from the work top 20 by (the thickness of the top plate 13 + the height of the leg 13 d). A full flat can be configured. In addition, the effect of smooth stop and frameless with excellent design and operability can be achieved.

Embodiment 7 FIG.
Next, a heat cooking system according to Embodiment 7 will be described. 10-12 is a figure which shows the heat cooking system which concerns on Embodiment 7, and FIG. 10 is a perspective view which shows a partial assembly state. FIG. 11 is a plan view showing a state in which the housing 11 is incorporated in the worktop 20. Further, FIG. 12 is a cross-sectional view showing a state in which the housing 11 is incorporated in the worktop 20. In addition, the same code | symbol is attached | subjected about the component which is the same as that of Embodiment 1, or equivalent, and the description is abbreviate | omitted.

  As shown in FIG. 10, a block-like operation unit 50 is fixed on the front body flange 11a. The operation unit 50 is composed of a unit thicker than the thickness of the top plate 13, and a plate insertion groove 50 a into which the top plate 13 is inserted is formed on the rear surface of the operation unit 50. Further, a block-shaped air supply / exhaust port 51 is fixed to the rear body flange 11a. The air supply / exhaust port 51 is formed of a member having substantially the same thickness as the top plate 13, and the outside air sucked by the cooling fan 52 provided in the housing 11 is heated coil 12 or a circuit board (not shown). After cooling, etc., it is discharged from the air supply / exhaust port 51 to the outside.

  As shown in FIG. 11, at the time of installation, first, the casing 11 in which the operation unit 50 and the air supply / exhaust port 51 are integrally molded is inserted into the opening 21 of the worktop 20. Next, the front end of the top plate 13 is inserted into a plate insertion portion 50a provided on the rear surface of the operation unit 50, and the both ends of the top plate 13 are placed in close contact with the body flanges 11a on both sides. At this time, the top plate 13, the air supply / exhaust port 51, and the work top 20 can constitute substantially the same surface. Furthermore, by providing a detachable air supply / exhaust port cover 53 at a position that encloses the boundary between the top plate 13 and the air supply / exhaust port portion 51, the rear end of the top plate 13 is pressed and fixed from above.

According to the above configuration, the members having a height higher than the surface of the worktop 20 are only the operation unit 50 and the air supply / exhaust port cover 53, and can be fully flattened with a simple structure. 50 and the air supply / exhaust port cover 53 can be used to realize a reliable fixing structure of the top plate 13, and since no adhesive or the like is required, installation and maintenance can be greatly improved.
Further, in the present embodiment, an example in which the operation unit 50 is fixed to the housing 11 in advance is shown. However, the operation unit 50 may be a detachable type, and in this case, the operation unit 50 is installed after the top plate 13 is installed. After the installation, the top plate 13 is pressed and fixed.

  Further, as shown in FIG. 12, a plate attachment / detachment switch (attachment / detachment detection unit) 54 formed of a reflective photo interrupter or the like is disposed below the top plate 13. The plate attachment / detachment switch 54 has a structure in which when the top plate 13 is attached, light from the light emitting element is reflected by the light receiving element and turned on as a switch. Conversely, when the top plate 13 is removed, the light is not reflected and is turned off, so that the presence or absence of the top plate 13 can be determined. The signal of the plate attachment / detachment switch 54 is transmitted to the drive circuit (control unit) 14, and when in the off state, the current from the drive circuit 14 to the heating coil 12 is interrupted to end the heating.

  According to such a configuration, during installation and maintenance, the heating coil 12 is not energized without the top plate 13 being attached. That is, since the driving of the heating coil 12 is ensured only when the top plate 13 is mounted, there is an effect that installation and maintenance can be performed safely. In addition, although the structural example of the to-be-contacted detection by the photo interrupter was shown as the plate attachment / detachment switch 54, you may comprise by the switch by a contact type. Further, the output of the plate attaching / detaching switch 54 is transmitted to the drive circuit 14 and the heating coil 12 is cut, but the power supply circuit may be directly cut off.

  Further, according to FIG. 11, an infrared temperature sensor (non-contact temperature detecting unit) 55 capable of detecting the temperature by being touched such as a thermopile is disposed in the lower part of the top plate 13 and in the central space of the heating coil 12. ing. The infrared temperature sensor 55 is disposed at a light collecting position where the lower surface temperature of the top plate 13 can be measured, and analogizes the temperature of the object to be heated in the pan 30 based on the temperature of the top plate 13. The output signal of the infrared temperature sensor 55 is transmitted to the drive circuit (control unit) 14, and an optimum heating sequence is realized by increasing or decreasing the amount of current to the heating coil according to the analog temperature of the object to be heated.

  According to the above configuration, since the infrared temperature sensor 55 that is not in contact with the top plate 13 is used instead of the thermistor that is conventionally adhered to the lower surface of the top plate 13, the installation pressing of the top plate 13 is performed. It becomes unnecessary to consider the influence of sensor contact due to pressure, and the top plate 13 can be configured to be detachable from the housing 11.
