Embodiment 1 FIG.
FIG. 1 is a perspective view showing a heating cooker 1 according to Embodiment 1 of the present invention. The heating cooker 1 is, for example, an IH cooking heater. The heating cooker 1 includes a housing 2, a top plate 3, and an operation panel 4, for example.

  Various devices are housed inside the housing 2. For example, the heating cooker 1 includes a control device 5 and a heating coil 6 inside the housing 2. The top plate 3 is provided on the upper part of the housing 2. The top plate 3 is made of, for example, plate-shaped tempered glass. A cooking utensil such as a pan is placed on the top plate 3. The operation panel 4 includes, for example, a thermal power adjustment knob.

  The heating cooker 1 further includes a grill 7. The grill 7 is a cooker for grilling fish and meat, for example. FIG. 2 is a view showing a cross section of the grill 7 of the heating cooker 1. The grill 7 includes, for example, a grill 8, an upper heater 9, a lower heater 10, a grill pan 11, and a lid 12.

  A food item 13 such as fish or meat is placed on the grill 8. In the example shown in the present embodiment, the grill net 8 includes a square net 8a and legs 8b provided at four corners of the net 8a.

  The cooking object 13 placed on the grill 8 is heated from above and below by the upper heater 9 and the lower heater 10. The upper heater 9 is disposed above the grill 8. The upper heater 9 heats the food item 13 placed on the grill 8 from above. The lower heater 10 is disposed below the grill net 8. That is, the grill 8 is disposed above the lower heater 10. The lower heater 10 heats the cooking object 13 placed on the grill 8 from below. The upper heater 9 and the lower heater 10 are supported by members forming the grill box 7a. For example, the grill cabinet 7 a is formed by a part of the housing 2. In such a case, the upper heater 9 and the lower heater 10 are supported by the housing 2.

  The grille 8 and the food 13 placed on the grille 8 are supported by the grill pan 11. The grill pan 11 is, for example, a square pan. The grill pan 11 is fixed to the front plate 14 (see FIG. 1). The front plate 14 is a member that closes the grill compartment 7 a from the front side of the heating cooker 1. The grill pan 11 is pulled out of the grill cabinet 7 a together with the front plate 14.

  The grill pan 11 is disposed below the grill 8 and the lower heater 10. For this reason, when the cooking object 13 placed on the grill 8 is heated by the upper heater 9 and the lower heater 10, oil dripped from the cooking object 13 falls on the upper surface of the grill pan 11. In the grill pan 11, a space 11 a for receiving oil or the like from the cooking object 13 is formed. In the example shown in the present embodiment, the grill pan 11 includes a bottom plate 15, a side wall 16, and a support portion 17.

  The grill net 8 is placed on the upper surface of the bottom plate 15. Oil or the like dripping from the object 13 falls on the upper surface of the bottom plate 15. The side wall 16 extends upward from the edge of the bottom plate 15. A space 11 a for receiving oil or the like from the object to be cooked 13 is formed by the bottom plate 15 and the side wall 16. That is, the space 11 a is a space above the bottom plate 15 and surrounded by the side wall 16. A support portion 17 is provided at the upper end portion of the side wall 16.

  The lid 12 is supported by the grill pan 11. For example, the lid 12 is placed on the support portion 17. A step corresponding to the outer shape of the lid 12 is formed on the support portion 17. When the lid 12 is placed on the support portion 17, the entire edge of the lid 12 faces the upper surface of the support portion 17 from above. When the lid 12 is appropriately placed on the support portion 17, the lid 12 covers the space 11a from above. The lid 12 is disposed below the grill 8 and the lower heater 10.

  FIG. 3 is a perspective view showing the lid 12. In the example shown in the present embodiment, the lid 12 includes, for example, a main body 18 and a handle 19. The main body 18 is made of, for example, a rectangular plate member. A large number of through holes 18 a are formed in the main body 18. The through-hole 18a is an opening for dropping oil or the like dripped from the cooking object 13 into the space 11a. The through-hole 18a is formed, for example, in a portion of the main body 18 that faces the net 8a of the grill net 8. Further, a through hole 18 b through which the leg 8 b of the grill net 8 passes is formed in the main body portion 18. The net 8 a is disposed above the lid 12 by placing the leg 8 b penetrating the through hole 18 b on the upper surface of the bottom plate 15 of the grill pan 11.

  FIG. 4 is a view showing the shape of the through hole 18 a formed in the lid 12. FIG. 5 is a view showing a cross section taken along the line AA of FIG. In the example shown in the present embodiment, the through hole 18a is circular. As shown in FIG. 5, chamfering may be performed on the edge forming the through hole 18 a on the upper surface and the lower surface of the main body 18. Chamfering may be applied only to the surface facing the lower heater 10 of the main body 18, that is, the upper surface of the main body 18. By chamfering, the diameter of the through hole 18a decreases from the upper surface of the lid 12 to a certain depth as the distance from the upper surface of the lid 12 increases. Thereby, the oil etc. dripped from the to-be-cooked item 13 are easily guided downward.

  When the cooking object 13 placed on the grill 8 is heated by the upper heater 9 and the lower heater 10, the oil dripped from the cooking object 13 passes through the through hole 18 a and falls to the upper surface of the grill pan 11. If the grill pan 11 is not cleaned for a long period of time, oil from the cooking object 13 accumulates in the grill pan 11. Further, part of the oil dripped from the object 13 falls on the lower heater 10. The oil that has fallen on the lower heater 10 may burn. Part of the oil dripped from the object to be cooked 13 falls onto the grill pan 11 while burning. When the burned oil falls on the grill pan 11, the oil accumulated in the grill pan 11 may catch fire. In preparation for such a situation, the diameter L of the through hole 18a is set to a value equal to or less than the oil extinguishing distance.

  The extinguishing distance is the distance between the gaps through which the flame cannot pass. If the diameter L of the through hole 18a is set to a value equal to or less than the flame extinguishing distance of the oil, even if the oil burns below the lid 12, the flame does not pass through the through hole 18a. That is, the flame does not reach above the lid 12. Since the lid 12 is disposed below the grill 8 and the lower heater 10, the flame does not reach the grill 8 and the lower heater 10 even if the oil accumulated in the grill pan 11 is lit.

  For example, in the disaster investigation report “Garbage disposal facility explosion disaster” prepared by the National Institute of Occupational Safety and Health in June 2006, the extinguishing distance of salad oil frequently used for cooking is 9.2 mm. It is described that there is. For this reason, you may set the diameter L of the through-hole 18a to the value (for example, 9 mm) below 9 mm. In addition, the above report describes that the extinction distance of palmitic acid is 6.9 mm and the extinction distance of oleic acid is 6.6 mm. For this reason, you may set the diameter L of the through-hole 18a to the value (for example, 6 mm) below 6 mm. In order to make the flame extinguishing effect more reliable, the diameter L of the through hole 18a may be set to a value of 3 mm or less (for example, 3 mm), which is half of the above value. In this way, the diameter L of the through hole 18a may be set to a value equal to or less than the extinction distance of the specific oil or specific fatty acid.

  The handle 19 is provided on the main body 18. The handle 19 protrudes upward from the upper surface of the main body 18. In the example shown in the present embodiment, a step corresponding to the outer shape of the lid 12 is formed on the support portion 17 of the grill pan 11. The lid 12 is placed on the support portion 17 so that the edge fits in the step. For this reason, if the handle 19 which protrudes from the upper surface of the main-body part 18 is not provided, the removal of the lid | cover 12 will become difficult. By providing the handle 19, the lid 12 can be easily removed.

  In the present embodiment, the example in which the through hole 18a is circular has been described. This is an example. The shape of the through-hole 18a may not be circular as long as the through-hole 18a is formed in the lid 12 so that the oil dripped from the to-be-cooked object 13 can pass and the flame when the oil burns cannot pass. For example, the shape of the through hole 18a may be a quadrangle. In such a case, the through hole 18a has a minimum width set to a value equal to or less than the oil extinguishing distance.

Embodiment 2. FIG.
FIG. 6 is a diagram showing a cross section of grill 7 of cooking device 1 according to Embodiment 2 of the present invention. FIG. 7 is a plan view showing a main part of the grill 7. FIG. 8 is a side view showing the main part of the grill 7. The grill 7 further includes, for example, a closing body 20, a temperature sensor 21, and a closing mechanism 22 in addition to the grill 8, the upper heater 9, the lower heater 10, the grill pan 11 and the lid 12. Each configuration of the grill 8, the upper heater 9, the lower heater 10, and the grill pan 11 is the same as each configuration disclosed in the first embodiment.

  The lid 12 is supported by the grill pan 11. For example, the lid 12 is placed on the support portion 17. A step corresponding to the outer shape of the lid 12 is formed on the support portion 17. When the lid 12 is placed on the support portion 17, the entire edge of the lid 12 faces the upper surface of the support portion 17 from above. When the lid 12 is appropriately placed on the support portion 17, the lid 12 covers the space 11a from above. The lid 12 is disposed below the grill 8 and the lower heater 10.

  FIG. 9 is a perspective view showing the lid 12 and members provided on the lid 12. In the example shown in the present embodiment, the lid 12 includes, for example, a main body portion 23, a side wall 24, a handle 25, and a receiving portion 26.

  The main body 23 is made of, for example, a rectangular plate member. An opening 23a for dropping oil or the like dripped from the food item 13 into the space 11a is formed in the main body 23. The opening 23a is formed, for example, in a portion of the main body 23 that faces the net 8a of the grill net 8. In the present embodiment, an example in which one opening 23 a is formed in the main body portion 23 is shown. A plurality of openings 23 a may be formed in the main body portion 23. In addition, a through hole 23 b through which the leg 8 b of the grill net 8 passes is formed in the main body portion 23. The net 8 a is disposed above the lid 12 by placing the leg 8 b penetrating the through hole 23 b on the upper surface of the bottom plate 15 of the grill pan 11.

  The side wall 24 extends downward from the edge of the main body 23. The lower end portion of the side wall 24 is placed on the support portion 17 of the grill pan 11. A cutout 24 a is formed in the side wall 24. The notch 24a opens, for example, downward. The handle 25 is provided on the main body 23. The handle 25 protrudes upward from the upper surface of the main body 23. The function of the handle 25 is the same as the function of the handle 19 disclosed in the first embodiment. The receiving part 26 is provided in the main body part 23. The receiving portion 26 protrudes upward from the upper surface of the main body portion 23.

  The closing body 20 is a member for closing the opening 23 a formed in the lid 12. In the example shown in the present embodiment, the closing body 20 has a flat plate shape. If the opening 23a can be closed, the shape of the closing body 20 is not limited to a flat plate shape. The closing body 20 is provided on the lid 12. The closing body 20 is disposed on the upper surface side of the lid 12, for example.

  The temperature sensor 21 detects the temperature of the grill box 7a. The temperature sensor 21 is supported by a member forming the grill box 7a. For example, the temperature sensor 21 is provided on a wall surface near the opening 23a among the wall surfaces forming the grill warehouse 7a. The temperature sensor 21 outputs a signal corresponding to the detected temperature to the control device 5. The control device 5 detects the occurrence of a flame based on the temperature detected by the temperature sensor 21. In the example shown in the present embodiment, the flame detection means is configured by the temperature sensor 21 and a partial function of the control device 5. For example, when the temperature detected by the temperature sensor 21 exceeds a preset temperature, the control device 5 detects the occurrence of a flame.

  The closing mechanism 22 is a mechanism for arranging the closing body 20 at a position where the opening 23a is closed. In the example shown in the present embodiment, a blocking unit is configured by a part of the function of the control device 5 and the blocking mechanism 22. The closing means normally holds the closing body 20 at a position where the opening 23a is opened. The closing means arranges the closing body 20 at a position where the opening 23a is closed when the flame detection means detects the occurrence of flame.

  The closing mechanism 22 includes, for example, a pin 27, a shaft 28, a spring 29, a motor 30, a cam 31, and a push rod 32.

  The pin 27 and the shaft 28 are members for holding the closing body 20 at a position where the opening 23a is opened. A through hole 23 c is formed in the main body 23 of the lid 12. The shaft 28 is provided in the main body portion 23. The shaft 28 protrudes into the through hole 23c from the wall surface of which one end forms the through hole 23c. The pin 27 is provided on the main body portion 23 via the shaft 28. The pin 27 can rotate around the shaft 28.

  The closing body 20 is provided on the lid 12 so as to be movable along the upper surface of the lid 12. 6 to 9 show a state in which the closing body 20 is arranged at an open position where the opening 23a is not blocked. In a state where the closing body 20 is disposed at the open position, the pin 27 is disposed between the closing body 20 and the opening 23a. The pin 27 can be arranged so that one end protrudes from the upper surface of the main body 23. When one end of the pin 27 is arranged so as to protrude from the upper surface of the main body 23, the closing body 20 arranged at the open position cannot contact the pin 27 and move to the closing position. The closing position is a position where the closing body 20 closes the opening 23a.

  The spring 29, the motor 30, the cam 31, and the push rod 32 are members for disposing the closing body 20 at a position that closes the opening 23a. The spring 29 is provided between the receiving portion 26 of the lid 12 and the closing body 20. The spring 29 presses the closing body 20 toward the opening 23a.

  The motor 30 generates a driving force for rotating the pin 27. A cam 31 is provided on the output shaft of the motor 30. When the output shaft of the motor 30 rotates, the cam 31 also rotates. The push bar 32 is disposed so that the angle formed with the pin 27 is, for example, 90 °. The push bar 32 passes through a notch 24 a formed in the lid 12, and the tip thereof faces the other end of the pin 27. When the cam 31 rotates, the push rod 32 moves so as to approach and separate from the other end of the pin 27.

  Next, the operation of the heating cooker 1 will be described with reference to FIGS. FIG. 10 is a flowchart showing the operation of the heating cooker 1 in the second embodiment of the present invention. Normally, the closing body 20 is disposed in the open position. The closing body 20 is held in the open position by projecting one end of the pin 27 from the upper surface of the main body 23.

  When a specific operation is performed on the operation panel 4, heating of the grill box 7a is started (S1). Specifically, the control device 5 causes a current to flow through the upper heater 9 and the lower heater 10 to cause the upper heater 9 and the lower heater 10 to generate heat. The control device 5 controls the current flowing through the upper heater 9 and the lower heater 10 based on information input from the operation panel 4.

  The control device 5 reads the temperature detected by the temperature sensor 21 (S2). Based on the temperature detected by the temperature sensor 21, the control device 5 determines whether or not a flame has occurred in the grill 7a (S3). The control device 5 stores in advance a temperature threshold for detecting the occurrence of a flame. For example, the control device 5 determines whether or not a flame has occurred in the grill 7a by comparing the temperature detected by the temperature sensor 21 with a temperature threshold.

  The temperature threshold is set to a temperature that the temperature sensor 21 does not detect in the normal use environment of the grill 7. For example, if the temperature detected by the temperature sensor 21 is equal to or lower than the temperature threshold, the control device 5 does not detect the occurrence of a flame. If the occurrence of flame is not detected in S3, the control device 5 returns to S2 and reads the temperature again.

  When the cooking object 13 placed on the grill 8 is heated by the upper heater 9 and the lower heater 10, the oil dripped from the cooking object 13 passes through the opening 23 a and falls to the upper surface of the grill pan 11. If the grill pan 11 is not cleaned for a long period of time, oil from the cooking object 13 accumulates in the grill pan 11. Further, part of the oil dripped from the object 13 falls on the lower heater 10. The oil that has fallen on the lower heater 10 may burn. Part of the oil dripped from the object to be cooked 13 falls onto the grill pan 11 while burning. When the burned oil falls on the grill pan 11, the oil accumulated in the grill pan 11 may catch fire. For example, when the temperature detected by the temperature sensor 21 exceeds the temperature threshold, the control device 5 detects the occurrence of a flame (Yes in S3).

  When detecting the occurrence of flame in S3, the control device 5 stops heating by the upper heater 9 and the lower heater 10 (S4). For example, when detecting the occurrence of a flame in S3, the control device 5 sets the current flowing through the upper heater 9 and the lower heater 10 to zero.

  Moreover, if the control apparatus 5 detects generation | occurrence | production of a flame by S3, the motor 30 will be driven (S5). Thereby, the opening 23a is obstruct | occluded by the obstruction body 20 (S6). 11 to 13 are diagrams for explaining the operation of closing the opening 23 a formed in the lid 12. When the motor 30 is driven in S5, the cam 31 rotates. Thereby, the push rod 32 moves so as to approach the pin 27. When the cam 31 rotates by a certain angle, the tip of the push rod 32 contacts the pin 27. The cam 31 rotates even after the tip of the push rod 32 contacts the pin 27. For this reason, the pin 27 is pushed by the push rod 32 and rotates around the shaft 28.

  When the pin 27 is rotated by a certain angle, one end of the pin 27 is detached from the closing body 20. Thereby, the closing body 20 is pushed by the spring 29 and moves to the opening 23a side. 12 and 13 show a state in which the opening 23 a is closed by the closing body 20. When the opening 23a is blocked by the closing body 20, even if oil burns below the lid 12, the flame does not pass through the opening 23a. That is, the flame does not reach the grill 8 and the lower heater 10. In addition, when the opening 23a is blocked by the closing body 20, sufficient oxygen is not supplied to the space 11a. Thereby, the fire gradually weakens, and finally the fire goes out (S7).

  Even if the opening 23a cannot be completely blocked by the closing body 20, the above effect can be realized if the gap formed between the closing body 20 and the lid 12 is equal to or less than the oil extinguishing distance. . For the same reason, when a gap is formed between the lid 12 and the grill pan 11, the width of the gap is preferably a value equal to or less than the flame extinguishing distance of oil.

  In the present embodiment, the example in which the closing mechanism 22 includes the motor 30 and the like has been described. This is an example. The closing mechanism may be any mechanism that can place the closing body 20 at the closing position when the occurrence of flame is detected.

  In the present embodiment, the example in which the closing body 20 is arranged on the upper surface side of the lid 12 has been described. This is an example. The closing body 20 may be disposed on the lower surface side of the lid 12. If the closing body 20 is disposed below the lid 12, it is possible to prevent oil from the cooking object 13 from being applied to the closing body 20 and the spring 29. In this case, the closing means moves the closing body 20 along the lower surface of the lid 12 to place the closing body 20 at a position where the opening 23 a is closed.

  FIG. 14 is a diagram illustrating a hardware configuration of the control device 5. The control device 5 includes a circuit including, for example, an input / output interface 33, a processor 34, and a memory 35 as hardware resources. The control device 5 realizes the functions disclosed in the embodiments by executing the program stored in the memory 35 by the processor 34. The control device 5 may realize part or all of the functions by hardware.
