Embodiment 1 FIG.
FIG. 1 shows the appearance of the main body of the heating cooker in the first embodiment.

  In the figure, the cooking device main body 1 has a top plate 2 made of, for example, crystallized glass on the top surface. Under the top plate 2, induction heating coils 3a, 3b, 3c are provided as heating sources (heating means), and the top plate 2 corresponds to the positions of the induction heating coils 3a, 3b, 3c. The circle is printed so as to indicate the location to be performed. The front surface of the cooking device 1 includes a grill 6 having a built-in heater for grilling fish provided with a grill door 5. In addition, on the front surface of the heating cooker body 1, there is provided an operation unit 4 for adjusting the heating source and the heating power of the grill 6 and adjusting the heating power so as to correspond to the induction heating coils 3a, 3b, 3c, for example. It is configured to adjust the thermal power by dial operation. Moreover, the thermal power display part 7 which displays the thermal power state of each induction heating coil 3a, 3b, 3c is provided as 7a, 7b, 7c so as to correspond to each induction heating coil. Furthermore, the display part 8 for notifying the operation state of the heating cooker main body 1 and the setting state of the grill 6 is provided. Further, on the top plate 2, high temperature caution display portions 9 for alerting the user when the top plate 2 becomes high temperature by the heating operation of the respective heat sources 3a, 3b, 3c are provided as the respective heat sources. Correspondingly, they are arranged as 9a, 9b, 9c. In addition, a grill high temperature caution display portion (high temperature display portion) 10 for displaying the temperature state of the grill door 5 is on the front side of the top surface of the top plate 2 and is substantially the same as the horizontal width of the grill 5 in a portion corresponding to the arrangement position of the grill 5. It is arrange | positioned with the length of. The high temperature caution display 9 and the grill high temperature caution display 10 are for informing the user that the grill door 5 is heated by the heating operation of the grill 6, and the top plate 2 is illuminated by a light source such as an LED. It is comprised so that it may irradiate from the lower part of.

  FIG. 2 is a functional block diagram showing the configuration inside the cooking device body. 2 that are the same as those described with reference to FIG.

  In the heating cooker body 1, heating command information is transmitted to the control unit 11 based on a user's heating command input from the operation unit 4. Upon receiving a heating command represented by a predetermined electrical signal, the control unit 11 performs a heating operation by operating the corresponding induction heating coils 3a, 3b, 3c and the heater of the grill 6 based on the command. In the vicinity of each induction heating coil 3a, 3b, 3c, a top plate temperature detector 12 for detecting the temperature of the top plate 2 is provided, and is arranged as 12a, 12b, 12c corresponding to each induction heating coil. The grill 6 is provided with a grill door temperature detection unit 13 that detects the temperature of the grill door 5.

  Moreover, the control part 11 transmits display data to the display part 8 which displays the operation state of the heating cooker main body 1, and the thermal power display part 7 which displays the thermal power of each heating source, and the control content is displayed on each display part. Control as follows. The top plate temperature detection unit 12 and the grill door temperature detection unit 13 (temperature detection means) that detect the temperature of the grill door 5 disposed in the vicinity of each induction heating coil 3 respectively determine the temperature detection value by the determination unit 14. For example, a known element such as a thermistor can be used.

  The determination unit 14 is a control device that performs display control of the high-temperature caution display units 9 and 10 based on the detected temperatures of the temperature detection units 12 and 13, and is a determination unit provided integrally or separately from the control unit 11. It consists of a microcomputer. When the determination unit 14 determines that the detection value of the top plate temperature detection unit 12 is higher than a preset temperature, the high-temperature caution display unit 9 arranged corresponding to each induction heating coil 3 is turned on. On the other hand, if it is determined by the heating operation of the grill 6 that the temperature of the grill door temperature detection unit 13 is higher than a preset temperature, the grill 6 is disposed on the top plate 2. It operates to light up the grill high temperature caution display section 10.

  A cooling fan 30 for cooling the circuit board such as the control unit 11, the induction heating coil 12, and / or the grill 6 is built in the main body. The cooling fan 30 takes in outside air from the top plate 2 or an intake port provided on the rear side of the main body, and cools the circuit board such as the control unit 11 by blowing cooling air. The cooling air that has passed through the circuit board passes through the outside of the induction heating coil 3 or the grill 6 to cool the respective members, and is discharged from the top plate 2 or an exhaust port provided on the rear side of the main body. At this time, a part of the cooling air can be exhausted from the front side of the main body in order to cool the electronic components provided on the front side of the main body. Further, the cooling air path of the cooling fan 30 is not limited to the above, and any path may be used as long as it can cool the electronic circuit, the grill, and the like in the main body. For example, as in an embodiment described later, air may be taken in from an intake port on the front surface of the main body, and cooling air may be exhausted to the side surface of the main body or the rear end side. A plurality of cooling fans 30 can be provided according to the number and arrangement of components that require cooling.

Next, the arrangement of the top temperature detector 12 will be described with reference to FIG. FIG. 3 is a cross-sectional view illustrating the arrangement of the top plate 2, the heating source 3, and the top plate temperature detection unit 12.
As shown in FIG. 3, an induction heating coil 3 a that is a heating source 3 is disposed below the top plate 2 so as to be in contact with the top plate 2. Furthermore, a top plate temperature detection unit 12a that detects the temperature of the top plate 2 in the vicinity of the induction heating coil 3a is disposed so as to be in contact with the top plate 2. The top plate temperature detection unit 12a is composed of, for example, a thermistor, and its resistance value changes according to the temperature of the top plate 2 in contact with it, the detection voltage at the determination unit 14 changes, and the temperature of the top plate 2 changes. Detect that has risen. Although the configuration for detecting the top plate temperature of the induction heating coil 3a portion which is the heating source 3 has been described here, the configuration and operation for detecting the top plate temperature of the induction heating coils 3b and 3c portions are the same.

Hereinafter, when the heating source 3 (induction heating coils 3a, 3b, 3c) disposed under the top plate 2 enters the heating operation, the high temperature caution display operation of the top plate will be described. The temperature of the top plate 2 near the heating source 3 (in this case 3a) rises due to heat conduction from the cooking container (object to be heated) heated on the plate 2. The top plate temperature detector 12 (in this case 12a) detects this temperature rise and the detected voltage changes, and the determiner 14 determines that a voltage corresponding to a preset temperature, for example, a temperature higher than 60 ° C., has been reached. When this is done, the high temperature caution display section 9 (9a in this case) of the top plate made up of LEDs (Light Emitting Diodes) is turned on. When it is determined that the temperature detected by the top plate temperature detecting unit 12a has dropped below 60 ° C. after the heating is finished, the determining unit 14 turns off the lit top plate high temperature warning display unit 9a.
Here, after heating is started, the temperature of the top plate 2 is 60 ° C. or higher and the top high temperature caution display unit 9a is turned on. However, even when the top plate high temperature caution display unit 9a is turned on simultaneously with the start of heating. Good.

  Next, the arrangement of the grill door temperature detection unit 13 will be described with reference to FIG. FIG. 4 is a cross-sectional view of the vicinity of the grille illustrating the arrangement of the grille door 5, the grille 6, and the grille door temperature detector 13. 4A shows a state where the grill door 5 is pulled out, and FIG. 4B shows a state where the grill door 5 is closed. A grill door 5 in which a window member 16 made of heat-resistant plate glass is attached to a frame member 15 forming a handle on a grill 6 disposed in the heating cooker main body 1, and a net on which a cooked food to be heated is placed. It is fixed to the rail 25 so that it can be pulled out simultaneously with a soup pan (not shown). The grill door temperature detection unit 13 for detecting the temperature of the grill door 5 is composed of a thermistor similarly to the top plate temperature detection unit 9 described above, and is energized by an elastic body 26 (for example, a spring) from the outline of the heating cooker body 1. It is attached in the state that was done. In the state where the grill door 5 is pulled out as shown in FIG. 4a, the grill door temperature detector 13 is in a state of projecting from the outline of the heating cooker body 1, and the grill door 5 is closed as shown in FIG. 4b. Then, the window material 16 forming the grill door 5 is in contact with the grill door temperature detector 13.

Next, the outline of the high temperature warning display on the grill door 5 will be described. When the heating operation of the grill 6 is started in a state where the grill door 5 is closed, the temperature of the window member 16 of the grill door 5 rises as the temperature inside the grill 6 increases. The resistance value of the thermistor that constitutes the grill door temperature detection unit 13 in contact with the window material 16 changes as the temperature of the window material 16 rises, and the detection voltage at the determination unit 14 changes. When it is determined from the detection voltage that the temperature of the window material 16 is equal to or higher than a predetermined temperature (for example, 60 ° C.) set in advance, the determination unit 14 displays the grill high temperature caution display unit 10 having a length substantially the same as the grill width. It operates so as to light up the LED that constitutes it, and informs the user that the grill door 5 is hot. The grill high temperature caution display unit 10 is provided on the upper surface of the main body and is visible in the vicinity of the grill from the upper side of the main body and has substantially the same length as the width of the grill 6, so when the grill door 5 becomes hot, this display By illuminating the part, the user can intuitively determine a point requiring attention.

  FIG. 5 is a flowchart showing the processing of the control unit 11 and the determination unit 14 from the start of use of the grill to after use. Hereinafter, the operation of the grill 6 and the high-temperature caution display operation will be described in detail with reference to this flowchart. When the operation signal input to the operation unit 4 is a signal for instructing the start of heating of the grill 6, the control unit 11 supplies a predetermined current to the heater of the grill 6 and starts heating (step S1). At this time, since the temperature inside the main body 1 rises due to the heating of the grill 6, the cooling fan 30 is also driven at the same time to allow relatively low temperature air to flow in from the outside and to discharge the warmed air inside the main body. To do.

  On the other hand, the determination unit 14 acquires a detection value of the grill door temperature from the grill door temperature detection unit 13 and determines whether or not the detection value is a predetermined value (for example, 60 ° C. or more) ( Step S2). This value is stored in advance in a memory built in the microcomputer or the like, and may be a fixed value, or may be dynamically calculated and generated according to conditions such as the operation mode of the grill 6 and the temperature. You can also In step S2, when the temperature of the grill door 5 is 60 ° C. or higher, the determination unit 14 causes the high temperature caution display unit 10 to display a high temperature caution (step S3). For example, a driving current is supplied to the LED, and the LED is controlled to light up. On the other hand, when the temperature of the grill door 5 is less than 60 ° C., the determination unit 14 does not display the high temperature warning on the grill high temperature warning display unit 10 (step S5), for example, continues the LED off / off state. .

  Next, the determination part 14 performs the process which determines whether the grill door 5 is closed (step S6). Specifically, the determination unit 14 determines the time from the start of grill heating from the timer or count information of the control unit 11 (step S6), and when the elapsed time t from the start of heating is shorter than a predetermined value T1. Then, it is determined that the temperature rises normally, and the process proceeds to step S4 without warning. On the other hand, when the elapsed time t is T1 ≦ t <T2 (predetermined time), the determination unit 14 determines that the grill door 5 may not be closed, and is careful about the high temperature of the grill as a prior warning before stopping heating. The display unit 10 is blinked (step S7). When the elapsed time t is equal to or greater than the predetermined time T2, the grill door temperature detection unit 13 is not in contact with the grill door 5, so that the detection temperature is likely not increased and the door is closed. It is determined that there is not, and a warning signal (interrupt signal) is transmitted to the control unit 11. Upon receipt of this warning signal, the control unit 11 transmits display data to the display unit 8 of the top board, and displays a message that “the heating of the grill 6 has been stopped because the door may not be closed” ( Step S8). Thereafter, the process moves to step S9, and the control unit 11 stops energization of the heater of the grill 6. Note that, when the determination unit 14 determines that the door is not closed, the grill high temperature caution display unit 10 may be used to display a notification that the operation has been stopped due to a door abnormality.

  When the determination unit 14 finishes the display process based on the door temperature (steps S2 to S7) (or in parallel), the control unit 11 monitors the operation input to the operation unit 4 and stops the grill 6 or operates the main power source. It is determined whether or not an off operation has been performed (step S4). And when there is no such operation, it returns to step S2 and continues the above-mentioned process. On the other hand, when the operation of stopping the grill 6 or the operation of turning off the main power is performed, the control unit 11 stops energization of the heater and stops the heating of the grill 6 (step S9). At this time, the control unit 11 notifies the determination unit 14 that the heating is completed using a notification signal.

  The determination unit 14 that has received this notification signal monitors the temperature of the grill door 5 even after the heating is completed, and continues the high temperature caution display by the grill high temperature caution display unit 10 until the temperature falls below a predetermined temperature (step S11). . On the other hand, when the detected value falls below a predetermined value, the determination unit 14 stops the high temperature caution display by the grill high temperature caution display unit 10 and also stops the power supply, and the temperature is lowered to the control unit 11. A notification signal to notify this is transmitted (step S12). Receiving this notification signal, the control unit 11 stops energization of the cooling fan 30 and ends the cooling process after stopping the heating.

  When the heating stop operation detected in step S9 is an operation for turning off the main power supply, the control unit 11 supplies power to a part of the circuit for detecting the reactivation of the main power supply (standby power supply). And the power supply to other circuits is stopped.

Here, when it is determined that the temperature of the window member 16 has become 60 ° C. or more after the heating operation of the grill 6 is started, the determination unit 14 lights the grill high temperature caution display unit 10. As shown in the flowchart, the grill door high temperature caution display unit 10 is turned on simultaneously with the start of the heating operation of the grill 6, and after the heating operation is completed, it is detected that the temperature of the window material 16 has become 60 ° C. or less. The display unit 10 may be turned off. In this case, when the control unit 11 starts energizing the heater of the grill 6, the control unit 11 outputs a notification signal informing the determination unit 14 of the start of heating. When receiving the notification signal, the determination unit 14 energizes and turns on the grill door high temperature caution display unit 10 as described above. Thereafter, the determination unit 14 monitors the detection value of the grill door temperature detection unit 13 and continues energization until the temperature becomes less than a predetermined value. 6, the same reference numerals as those in FIG. 5 represent the same or equivalent processes as those in FIG. 5, and the control shown in FIGS. 5 and 6 is the same in the heating cooker according to the embodiment described later. To be done.

Further, the determination unit 14 is turned on so as to blink when the detected temperature is low and to light up when the temperature is equal to or higher than the predetermined temperature according to the detection value of the grill door temperature detection unit 13 as the process of step S3 of FIG. 5 or FIG. The state may be changed to prompt the user to pay attention to the high temperature of the grill door 5. Further, a display color for high temperature attention may be changed according to the temperature by combining a plurality of colors of LEDs. These blinking and coloration patterns are stored in the microcomputer's built-in non-volatile memory corresponding to each temperature range, the temperature range to which the detected temperature belongs is determined during execution of step S3, and the pattern corresponding to the temperature range is read out. It can be executed by energizing the LED or the like.

Further, when the detection value of the grill door temperature detection unit 13 is not changed or it is determined that there is an abnormality in the grill door temperature detection unit 13 in spite of the grill 6 being heated by a command from the control unit 11. The determination unit 14 stops the heating operation of the grill 6 by the control unit 11 and lights the grill high-temperature caution display unit 10 differently from the time of other display (for example, blinking at a high speed). A notification is made that an abnormality has occurred in the grill.

  In addition, when the disconnection or short circuit of the grill door temperature detection unit 13 is detected by the determination unit 14 before the start of the heating operation of the grill 6 (before step S1), it is similarly determined as an abnormal state. Even when there is a heating command, the heating operation is not performed. Then, in the same manner as described above, the grill high temperature caution display unit 10 is turned on differently from the other display to notify the user that an abnormality has occurred in the grill. This process can provide higher safety. Disconnection or short circuit is when the voltage value / current value of the grill door temperature detection unit 13 wiring is converted into a digital signal by an analog-digital converter or the like, or when the current value is less than or equal to a predetermined value, The detection circuit can be configured to have a significant voltage and can be detected by inputting a detection signal to the microcomputer.

When the determination unit 14 detects that the LED of the grill high temperature caution display unit 10 is lit but does not light the LED, or when the determination unit 14 detects an overcurrent due to a short circuit of the LED, etc. The determination unit 14 transmits a notification signal indicating the occurrence of abnormality to the control unit 11, and controls the control unit 11 that has received this signal to stop the heating operation of the grill 6 or not to start the heating operation.

As described above, the top plate temperature detection unit 12 disposed in each heating source 3 detects the top plate temperature in the vicinity of each heating source 3, and when that portion is hot, a high temperature caution corresponding to each heating source 3 is used. Since the display means 9 is turned on, the user can easily recognize which part of the top 2 is hot.
In particular, in the conventional cooking device, the temperature of the top plate is estimated from the inside temperature of the grill (roaster), and even though the user can recognize that the top plate is hot, the grill (roaster) It was difficult to recognize that the temperature was high. There is also a problem that the user cannot distinguish whether the top plate is hot due to cooking on the grill (roaster section) or cooking on the top plate. It was. On the other hand, according to the heating cooker of this embodiment, since the grill high temperature caution display unit 10 having a width substantially close to the width of the grill is provided immediately above the grill and at a position (near) from the heating unit 3, The effect of facilitating the discrimination from the high temperature caution display of the source can be obtained, and the high temperature state of the grill can be recognized from above the heating cooker body, so that the safety can be further improved for the user. Here, the width of the grill high temperature warning display unit 10 does not have to be the same as the width of the grill, but in order to associate the width with the grill, it is necessary to secure a width close to the width of the grill. 70 to 120% is desirable.

Further, the temperature of the window material 16 constituting the grill door 5 is directly detected by contacting the grill door temperature detection unit 13, and the grill high temperature caution display unit 10 is operated when the temperature of the window material 16 exceeds a predetermined value. As a result, the user can recognize that the grill door 5 is hot.
Furthermore, in the conventional cooking device, the temperature in the grill is detected and the top plate temperature is estimated. However, between the grill 6 and the top plate, there are parts that are sensitive to high temperatures such as an LED or a liquid crystal display device. Since it is arranged, the grill 6 and the top plate are provided so as to sandwich the cooling air passage. Therefore, when the heat of the outer wall of the grill is transmitted to the top plate across the cooling air passage and the top plate reaches a high temperature such as 80 ° C. (Reference: Patent Document 1, paragraph 0025), it is a considerably late time from the start of heating. is there. On the other hand, the temperature of the grill door 5 that is directly exposed to the high temperature inside the grill cabinet rises faster than the top plate. Therefore, in the conventional heating cooker, even if the top plate is in a low temperature state, the user can grill. When the door 5 is inadvertently touched, there is a problem that the heat of the grill door 5 is surprised. In that respect, in the heating cooker of this embodiment, since the caution display with respect to the temperature of the grill door 5 is performed according to the temperature of the grill door 5, a safer and more comfortable heating cooker can be provided.

In addition, when the detection value of the grill door temperature detection unit 13 after a certain period of time has elapsed after the start of the heating operation of the grill 6 is equal to or less than the value preset in the determination unit 14, the fact that the grill door 5 is open is notified. Since it was made to do, there exists an effect of preventing the cooking failure in the grill 6.
In addition, since the lighting method or display color of the grill high temperature warning display unit 10 is changed according to the detection value of the grill door temperature detection unit 13, the user can generally determine the temperature of the grill door 5, so that the grill There is an effect that the high temperature state of the door 5 can be notified to the user more accurately.
In addition, when it is determined that there is an abnormality in the grill door temperature detection unit 13 or the grill high temperature caution display unit 10, the heating operation of the grill is not stopped or operated, so that the safety of the cooking device is further improved. There is an effect that can be.
In addition, all the processes demonstrated in this embodiment are applicable to the heating cooker of embodiment mentioned later.

Here, since the metal has a property of high thermal conductivity, the frame body 15 is provided in a substantially U shape (or a substantially B shape), and a gap (air layer) is provided between the frame body 16 and the window frame 16. It is configured to ensure and suppress heat conduction to the window frame 16.

  Further, in this embodiment, the grill high temperature caution display portion 10 a is provided on the back side of the decorative member 21 provided between the kitchen table 22 and the grill 6, and the makeup is made by shining light from behind the decorative member 21. The member 21 is made to shine. This decorative member 21 is a translucent member that fits into a gap formed between the back surface of the kitchen table 22 and the main body after the heating cooker main body is inserted into the kitchen table 22. Since the grill high temperature caution display portion 10a and the decorative member 21 are provided at the grill position closer to the grill door 5, it can be more intuitively notified that the grill door 5 is hot. Further, due to the light diffusing action of the decorative member 21, the light that has passed through the decorative member 21 is reflected on the upper surface portion (handle 20) of the grill door 5, and the light can be seen from directly above the grill door 5. At this time, the light emitted from the decorative member 21 may be light of a color such as red that makes it easy to visually recognize the caution state.

  The grill high temperature caution display unit 10a is provided in a position closer to the top plate 2 in the vertical direction than the partition wall 1a provided to suppress the heat of the grill 6 from being conducted to the top plate 2 and the induction heating coil 3. And is protected from heat conduction from the grill 6. An outer peripheral space 62 is provided as a cooling air passage between the partition wall 1a and the outer wall surface of the grill 6, and a cooling air passage provided in the decorative member 21 by the suction force of the cooling fan 30 incorporated in the main body. Or outside air with low temperature is suck | inhaled from other ventilation holes, and a cooling wind flows so that an outer wall may be cooled through the cooling air path by the side of the grille 6 outer wall. The cooling air also has an effect of preventing heat from being transmitted from the grill 6 side to the top plate 2 side.

  The grill door temperature detection unit 13 a is a non-contact temperature sensor provided on the grill outer peripheral front panel 61 provided at the periphery of the opening of the grill 6. An infrared sensor that measures the emitted infrared light is used. The grill door temperature detector 13 a is provided in the expansion space 62 a of the outer peripheral space 62 and is protected from the heat of the grill 6. That is, since the height h2 of the expansion space 62a is higher than the space height h1 between the normal upper wall surface of the grill 6 and the partition wall 1a, the heat shielding effect is high and the grill door temperature detecting portion 13a is destroyed. Temperature measurement accuracy can be improved. In particular, in this embodiment, since the expansion space 62a is provided at the front end portion of the grill 6 without the heater 63, the effect of protecting the heater 63 against heat is high.

  Thus, when a non-contact temperature sensor is used, there is no problem of erroneous temperature detection due to contact failure compared to the contact type. Also, the grill door 5 needs to be in contact with the grill 6 or the grill outer peripheral front panel 61 with as little gap as possible in order to prevent smoke leakage. However, as shown in FIG. Unlike the case of pressing against the grill door 5, no force is applied to the grill door 5, so that the addition of the sensor does not cause smoke leakage. On the other hand, since an infrared sensor is weaker to heat than a thermistor, it is a sensor that is difficult to employ in a portion having a high temperature such as the periphery of a grill. This point is superior to the contact-type sensor on the premise that the temperature is high as shown in FIG. In this embodiment, this problem is solved by providing the non-contact grill door temperature detector 13 in the cooling air passage and in the expansion space of the outer peripheral space 62 having high heat shielding properties.

  The frame member 15 is provided with a space so as not to block the grill door temperature detector 13a. FIG. 8 is a view showing the back side (the inside of the grill) of the grill door 5. The frame member 15 has a notch (space portion) at a position facing the grill door temperature detector 13 a, and the window member 16. Part 16a is exposed. For this reason, the grill door temperature detector 13a is made of an exposed surface that the user may touch, that is, a material such as glass, rather than detecting the temperature of the metal frame 15 whose temperature rises quickly. The temperature of the window material 16 can be detected. Further, in the problem of residual heat after using the grill 6, conversely, the metal frame member 15 has a rapid temperature drop, but the window member 16 having a low thermal conductivity may maintain a relatively long and high temperature state. . In this respect, in this embodiment, since the temperature of the window material 16 is measured and displayed at a high temperature, it is possible to provide a cooking device with higher safety.

  Further, in this embodiment, a light shielding portion 22 is provided on the grill door 5. When the infrared sensor is used for the grill door temperature detection unit 13a, the light shielding unit 22 prevents the infrared sensor from detecting the temperature outside the grill door 5 and improves the temperature detection accuracy. On the other hand, the upper end of the grille door 5 (so that the temperature of the window member 16 does not rise locally due to the high temperature in the space surrounded by the light shielding portion 22 and the window member 16, the frame 15, and the grill outer peripheral front panel 61 ( Alternatively, an air passage is formed between the light shielding portion 22) and the grill outer peripheral front panel 61 (or the decorative member 21).

  In the above description, a non-contact type sensor has been described as the grill door temperature detection unit 13a. However, the structure of the grill door 5, the position of the grill door temperature detection unit 13, the structure and arrangement of the grill high temperature caution display unit 10, and the like. Each has advantages and effects not found in the prior art, and the non-contact type grill high temperature caution display section 10a shown in FIG. 7 can be replaced with the contact type temperature sensor described in the first embodiment. I do not care.

  Further, the handle 20 does not need to be provided at the upper end portion of the grill door 5, and may be provided at the lower end portion of the grill door 5 as described in FIG. In this case, since the handle 20 does not hide the window material 16, the user is more likely to touch the window material 16, and thus the necessity for high-temperature display is increased.

  Further, in the above description, a notch is provided in a part of the frame member 15 as shown in FIG. 8, but the window member 16 is exposed to the grill door temperature detector 13a, and the temperature of the window member 16 can be detected. If possible, it is not necessary to have a notch, and a hole may be provided, or the upper end of the frame member 15 may be omitted over the entire width of the frame member 15. In the above description, the temperature of the window member 16 is intended to be measured. However, if the temperature on the door surface side, which is likely to be touched by the user, can be measured, a surface side member other than the window member 16 is used. You may measure.

Embodiment 3 FIG.
Next, an embodiment for performing high temperature display using the grill door 5 itself will be described. FIG. 9 is an external view of the cooking device with the top plate 2 removed and the inside visible. FIG. 10 is a cross-sectional view showing the arrangement of the grill high temperature caution display portion 10bc, and FIG. 11 is a front view of the heating cooker and shows a state where the grill door 5 is removed. 9 to 11, the same reference numerals as those described above represent the same or corresponding parts, and hereinafter, a structure for performing high-temperature display using the grill door 5 centering on the characteristic parts of this embodiment. Will be described.

  As shown in FIGS. 9 and 10, the cooking device of this embodiment has a structure that informs the user that the grill 6 is hot by irradiating the grill door 5 with light from the back side. . In the example of FIG. 10, the translucent member 10 c is fitted into the handle 20 of the grill door 5, and the light irradiated from the heating cooker body 1 side transmits through the translucent member 10 c and diffuses. When the light-sensitive member 10c shines, a high temperature warning is displayed. The light emitting element (light source part) 10b is provided on the grill outer peripheral front panel 61. In this embodiment, the light emitting element 10b and the translucent member 10c constitute the grill high temperature caution display part 10. Since the grill outer peripheral front panel 61 faces the rear surface of the grill door and is close to the grill door 5 when the grill door 5 is closed, the grill door 5 (or the handle 20) can be illuminated linearly from a close range. Further, similarly to the above-described embodiment, the grill outer circumferential space 62 is a cooling air passage, and an expansion space 62a is provided, and the light emitting element 10b is disposed in the expansion space 62a. Can be protected from heat. Further, the advantage of providing the light emitting element 10b at a position where the heater 63 is not provided in the vertical direction is the same as that described for the grill door temperature detecting unit 13 in the above-described embodiment. That is, this structure can prevent the element from being thermally destroyed.

  The light emitted from the light emitting element 10b passes through the window material 16, enters the back surface side of the light transmissive member 10c, passes through the inside while diffusing, and is emitted from the surface of the light transmissive member 10c. Since the translucent member 10c is provided so as to be inclined obliquely upward, the translucent member 10c has a structure that is easily visible from the front or from above. In this embodiment, the light emitting element 10b and the translucent member 10c constitute a high temperature display means.

  The metal frame member 15 is provided with a space where light passes so as not to obstruct the passage of light. For example, a portion corresponding to a notch, a hole, or the upper end of the grill door is a door. It is possible to adopt a structure such as omitting the entire width of the.

  In order to suppress heat conduction from the grill outer peripheral front panel 61, the light emitting element 10b is preferably arranged at a slight interval as shown in FIG.

  When high temperature display is performed using the grill door 5, it is possible to incorporate a light emitting element in the grill door, which is a movable part, and to be electrically connected to the main body, but with sufficient consideration for durability, heat resistance, etc. Need to design. It is also conceivable that a light emitting element is provided on the operation unit 4 side where no heat is generated, light is refracted from the side surface side of the grill door 5 using a light guide member, and the handle 20 is lit. However, in this method, it is necessary to refract light at the bent part of the handle part, and to radiate light in the front direction or upward by the horizontally long light diffusion part, so the light is strong at the right end of the handle near the light source, and the center There is a problem that the handle part cannot be shined as expected, such as light weakening at the left and right ends. Further, since the window material 16 made of heat-resistant glass is thin, it is difficult to guide the light from the side and shine on the front side, and adopt a structure in which a light diffusion plate having an inclined surface is sandwiched between two heat-resistant glass plates. It is difficult.

  On the other hand, in this embodiment, since the light emitting element 10 b is provided on the grill outer peripheral front panel 61, the grill door 5 or the handle 20 can be irradiated from the back side of the grill door 5. Therefore, there is an effect that the glass surface of the grill door 5 and the handle 20 can freely emit light. Further, when the light emitting element 10b is provided in the grill outer peripheral space such as the grill outer peripheral front panel 61, the influence of the heat of the grill 6 on the light emitting element 10b becomes a problem. In this embodiment, the heater position of the grill 6 is a problem. The problem of the thermal destruction of the light emitting element 10b is solved by devising the structure around the grille 6 such as the cooling air passage in the outer peripheral space. The outer peripheral space of the grill 6 need not be provided over the entire periphery of the grill 6, and may be only a part of the vicinity of the space along the outer wall of the grill.

  In FIG. 11, a plurality of substantially circular light emitting elements 10b are arranged in the longitudinal direction of the handle. However, the shape and structure of the light emitting element 10b are not limited to this and may be anything. For example, it is also possible to provide one rectangular light emitting element corresponding to the handle 20 or the portion of the window material 16 that emits light so as to extend in the longitudinal direction. In this case, there is an effect that light can be emitted more uniformly.

  FIG. 12 is a modification of the cooking device of FIG. 10, and the light emitting element 10 a is not arranged in the outer peripheral space of the grill 6 having severe heat conditions, for example, the position above the partition wall or the outer peripheral space. It is the example provided in the position which separated the wall which can restrict | limit the movement of the hot air from. The light emitted from the light emitting element 10a can reach the back surface of the translucent member 10c through the hole by the light reflecting member 10d provided in the outer peripheral space, and the surface of the translucent member 10c can emit light. The light reflecting member 10d is a part of the high temperature display means, and any light guiding means can be used as long as it can change the direction from the light incident direction from the light emitting element 10a and emit light to the rear surface of the grill door, such as a mirror or a prism. May be used.

  By adopting such a structure, the influence of the heat of the grill 6 on the light emitting element 10a can be further reduced. Note that the handle 20 of this example has a shape in which the central portion is disposed at a distance from the window member 16 of the grill door 5 and both end portions are connected to the grill door 5 (or the frame member 15). A light transmissive member having low thermal conductivity is fixed to the surface of the window member 16 facing the handle 20. This member (protective member) is provided to protect the finger from directly touching the window material 16.

Further, as shown in FIG. 13, it is possible to make the surface of the grill door 5 not the handle 20 shine. The window material 16 may be provided with a light diffusing surface 10e such as a fine unevenness to further improve the visibility. As a means for diffusing light, a light diffusing member can be provided as a separate member on the back surface or the front surface of the window material 16. At this time, it is preferable to provide an inclined surface that reflects light upward so that it can be easily seen from above.
As described above, when the surface of the grill door 5 is shined, the member that becomes high temperature is shined. Therefore, there is an advantage that the portion or member that requires attention for the user can be easily understood intuitively.

FIG. 14 is a modification of FIG. 13 and is an embodiment in which the light emitting element 10a is provided on the outer surface side of the grille outer peripheral space instead of the inner surface side of the partition wall 1a. The partition wall 1a has a curved portion so that the front side of the grill, that is, the front side of the main body extends downward (closer to the front end side of the grill) than the central portion or the rear side. In particular, in this embodiment, the surface of the partition wall 1a is lowered to a position lower than the upper end of the grill door 5, and a gap is secured on the back surface side of the upper end of the grill door 5. The light emitting element 10a is provided on the outer surface side of the partition wall 1a, and is protected from the heat of the grill 6 by the partition wall 1a. The space between the partition wall 1a and the wall surface of the grill 6 (the outer peripheral space 62) may be a cooling air passage as described above, or merely a heat insulating layer by air without actively passing the cooling air. Also good. In the case of the cooling air passage, not only the cooling air is taken in from the front surface of the main body, but also the cooling air sucked from the rear side of the main body is caused to flow from the side surface of the grill to the cooling air passage of the grill 6 to It is also possible to configure so that the air is exhausted from.
Further, since the curved portion has a light reflecting surface, the light diffusing surface 10e of the grill door 5 can be efficiently irradiated with light. Although it is conceivable to apply a highly reflective paint or the like on the reflecting surface, a metal surface such as iron or metal plating can be used as it is. Further, in this embodiment, since the distance from the grill door 5 to the light emitting element 10a can be secured, the grill door 5 can be illuminated in a wider range, and unevenness of the light intensity can be suppressed. Moreover, the high temperature warning of the grill door 5 can be displayed long in the front lateral width direction of the grill door 5 with a small number of light emitting elements 10a. First, the distance to the grill door 5 can be secured in the depth direction. Further, when light is refracted as shown in FIG. 14 (refraction is not essential), there is an advantage that a distance can be secured in the vertical direction.

Needless to say, another light guide member 10d may be used as shown in FIG.
In this embodiment, the front end of the partition wall 1a is used as a heat shielding member for the grill outer peripheral space 62. However, by using a member different from the partition wall 1a, the light emitting element 10a (or another grill high temperature caution display member is provided from the grill outer peripheral space 62. ) May be suppressed, and this separate member may function as a partition wall that reduces infrared radiation from the grill 6.
The broken line in FIG. 14 is an imaginary line indicating the position of the light diffusing member 10c when the handle 20 and the light diffusing member 10c are provided when the handle 20 is provided near the upper end as shown in FIG. Thus, the structure of this embodiment can be used not only when the grill door 5 is lit but also when the handle 20 is lit.

  Further, when the light emitting element 10a is arranged above the partition wall 1a (it is not always necessary to be the upper projection area of the partition wall), the handle 20 is made to shine using light guide means from above the grill door 5. You can also

In the above description, an example in which a light emitting element or the like is provided on the upper side of the grill 6 has been described. Similarly, light is guided from the lower side of the grill 6, that is, from the grill outer peripheral front panel 61 or below. It is also possible to make the grill door 5 or the handle 20 shine.
FIG. 15 is a cross-sectional view of a heating cooker in which high-temperature display means such as light emitting elements are arranged near the lower end of the grill, and FIG. 16 is a front external view thereof. On the outer side (lower side) of the bottom surface of the grill 6, there is another partition wall 1 b that suppresses heat conduction so that the heat of the grill 6 does not hurt the kitchen. A space between the grill bottom and the partition wall 1b is also a grill outer peripheral space 62, and a grill outer peripheral front panel 61 is provided on the front side of the main body so as to cover the outer peripheral space. Cooling air from the cooling fan 30 is blown from the rear or side of the grill to the outer peripheral space of the grill to cool the bottom and outer peripheral spaces of the grill (exhaust air is folded near the front end of the main body and guided to the rear. Or can be pulled out to the side, front, etc.). In particular, when the grill 6 is used, a saucer (not shown) is placed on the bottom of the grill so as to receive oil that has fallen from the object to be cooked. However, the cooling fan 30 does not ignite when the oil becomes hot. There is a role to keep the temperature of the saucer below the ignition point of oil through the bottom of the grill. In this case, it is not necessary to fill the saucer with water, and it is possible to suppress the phenomenon that the water in the saucer evaporates to increase the moisture of the food to be cooked. ing.

In this embodiment, the light emitting element 10b is arranged in the grill outer peripheral space (cooling air passage) in the same manner as in the above-described embodiment, and the handle 20 having the translucent member 10c while protecting the light emitting element 10b from the heat of the grill 5. Is made to shine from the back side of the door. Here, the light emitting element 10b may have the same shape as the above-described embodiment, but a light emitting element having a horizontally long shape as shown in FIG. 16 may be used. The light emitting element 10b may be a light source itself having a horizontally long shape, or a combination of a small light source and a light guide plate 10d that diffuses light from the light source in the horizontal direction. In particular, since the outer peripheral space on the bottom side of the grille is deep and other components are rarely disposed, it is easy to secure a distance and a space for sufficiently diffusing light in the lateral direction.
The bottom surface of the main body 1 can be used as the partition wall 1c, and a partition wall 1c that restricts the movement of heat can be separately provided between the bottom surface of the main body and the bottom surface of the grill.
Further, as another application example, it is possible to provide the light emitting element 10a under the outer surface of the partition wall 1c, and the same effect can be obtained by making the bottom surface of the grill as shown in FIG. be able to.
Moreover, you may perform a grill high temperature display similarly using the side of the grill outer periphery front panel 61. FIG.

Embodiment 4 FIG.
In the above embodiment, the user is effectively notified of the high-temperature caution display on the top plate of the heating cooker and the grill door 5. Next, the grill door 5 is used during the use of the heating cooker. In order to protect a user from a high temperature state, an embodiment of a heating cooker capable of further enhancing the function of this protection will be described.

  FIG. 17 is a front view showing the appearance of the heating cooker according to this embodiment. The configuration of the main body of the heating cooker according to the present embodiment will be described below with reference numerals. The parts described in the first to third embodiments are denoted by the same reference numerals and description thereof is omitted.

  The heating cooker body 1 includes a top plate 2, an operation unit 4, and the like and a grill 6 including a door 5 on the front surface of the heating cooker body 1. In the grill door 5, a window member 16 made of heat-resistant glass having permeability is fixed to the frame member 15. The frame member 15 has a plurality of holes 17 on both sides of the frame member 15 (vertically in the present embodiment, vertically) for engaging a handle 18 that a user puts on to open and close (draw out) the grill door 5. 3 stages). Further, as shown in FIG. 18, the handle 18 is provided with an L-shaped claw portion 19 on both sides of the handle 18 so that the claw portion 19 is hooked by the hole portion 17 of the frame member 15. .

Subsequently, a method of using the handle 18 will be described with reference to FIG. FIG. 19 is a cross-sectional view showing a state of the handle 18 and the claw portion 19 that are hooked on the frame portion 15 of the grill door 5. As shown in FIG. 19, the claw portion 19 is inserted into the hole portion 17, and after the insertion, the claw portion 19 is lowered to be hooked and fixed to the hole portion 17. When removing the handle 18 from the frame member 15, first, the handle 18 is pulled up first, the claw portion 19 that is hooked in the hole 17 is removed, and then the handle portion is separated from the frame member 15 by pulling it forward. It becomes possible. In the present embodiment, the hole 15 is provided in the frame member 15 in three vertical stages, so that the position of the handle 18 of the grill door 5 can be changed in three stages. FIG. 20 shows the appearance of the heating cooker body 1 in a state where the position of the handle 18 is moved to the middle stage of the grill door 5.

As described above, since the handle 18 can be fixed at an arbitrary position of the grill door 5, when pulling out the grill door 5, the handle 18 can be connected to the upper stage or the lower stage to make it easy to use. Further, when the temperature of the glass surface rises during heating or after use, the handle 18 can be disposed at a position (guard position) where a part of the window material 16 is covered by the handle 18. It is possible to reduce the chance of the grill door 5 being brought into contact with the window material 16 having a particularly high temperature, thereby improving safety.
Further, since the handle 18 can be fixed at an arbitrary height corresponding to the hole portion 17, the handle can be easily used and the usability of the grill can be improved.
Moreover, since it can fix by using the other hole part 17 which does not use another handle | steering-wheel 18, and a handle can be added, the opportunity to contact the window material 16 of the grill door 5 which becomes especially hot. Can be further reduced, and safety can be further improved.
In the present embodiment, the structure in which the claw portion 19 of the handle 18 is hooked to the hole portion 17 of the frame member 15 has been described, but any configuration may be used as long as the handle can be moved. It is not limited to the structure described in the form.

Embodiment 5 FIG.
The fourth embodiment is configured to improve the safety by changing the handle position of the grill door. In the present embodiment, another embodiment that can further improve the safety will be described. .

FIG. 21 is an external view of the main body of the heating cooker showing the present embodiment. The parts described in the fourth embodiment are given the same reference numerals and description thereof is omitted. The grill door 5 provided in the heating cooker body 1 has a handle 20. The difference from the above-described third embodiment is that the handle 20 is configured so as to be divided in the vertical direction, and the handle 20 is structured such that a part of the handle 20 is held by a slit 21 provided in the frame member 15. The holding structure of the handle 20 will be described with reference to FIGS. FIG. 22 is a perspective view for explaining the structure of the frame member 15 and the handle 20 (in the description, the upper part is 20a and the lower part is 20b) configured to be vertically split, and FIG. It is sectional drawing and a front view which show the pinching state of 20.

  The structure and operation of the handle 20 will be described with reference to FIGS. As shown in FIG. 22, the handle 20 is arranged on the frame member 15 in a state where it can be divided vertically. The handle 20 (20a, 20b) has a sandwiched member 22 (22a, 22b) having a T-shape on both sides of the handle body. The pinched member 22 is configured to be fitted into a slit 21 provided in the frame member 15. Although not shown in FIG. 22, as shown in FIG. 23, the sandwiched member 22 is sandwiched between the both sides of the sandwiched member 22 by the sandwiching members 23 and 24 provided in the frame member 15. Is retained. The sandwiching members 23 and 24 are made of an elastic body such as hard rubber, and hold the handle 20 by sandwiching the sandwiched member 22 of the handle 20. Since the sandwiched member 22 is sandwiched between the sandwiching members 23 and 24 that are elastic bodies, when a force is applied to the handle 20 in the vertical direction along the opening of the slit 21, the handle 20 moves in the direction in which the force is applied. (Sliding) and removing the applied force, the handle 20 is fixed in that position.

  As described above, the handle 20 is configured to be vertically divided, and the narrowed member 22 provided on the handle 20 is sandwiched and held by the holding members 23 and 24 provided in the frame member 15, The handle 20 can be moved and arranged at an arbitrary position on the grill door 5, and the degree of freedom of the installation position of the handle is further increased as compared with the embodiment described in the third embodiment. And when the handle | steering-wheel 20 is moved to a guard position, the opportunity to contact the window material 16 which becomes especially high temperature of the grill door 5 heated during grill cooking can be reduced, and safety can be improved. I can do it.

  Further, the handle 20 has a structure that can be divided up and down, and the divided handles 20a and 20b can be independently slid up and down. It becomes possible to make it function as a guard member which prevents a user's contact to the grille door 5 more effectively. FIG. 24 shows an appearance of a heating cooker in which the handle 20 divided vertically is arranged on the grill door 5 and the protection function is further enhanced.

  In the present embodiment, the method of fixing the handle to an arbitrary position by the sandwiched member and the pinching member has been described. However, the method of arbitrarily fixing the handle is not limited to this, and the handle is divided into upper and lower parts and arranged at an arbitrary position. Any method may be used as long as it can be fixed.

The specific detailed structure and the like of the above-described embodiment do not limit the scope of the present invention at all, and can be applied to various forms based on these descriptions. For example, in the above-described embodiment, the temperature of the grill door 5 is detected and the high temperature display is performed. However, the structure and arrangement of the high temperature display means cannot detect the temperature when detecting the temperature in the grill cabinet. In addition, the present invention can also be applied to a case where high temperature display is performed based on the operation of the grill (heating start / heating end / cooling period after heating end).
Needless to say, the handle 20 having a function of protecting the plate glass can be used without being restricted by specific control.
Further, the plurality of embodiments and examples can be freely combined by taking advantage of each advantage.

  The present invention is applicable to a cooking device having a grill.
