heating cooking chamber 100A according to the present embodiment will be further described with reference toFIG. 5 .FIG. 5 is a schematic cross-sectional view illustrating theheating cooking chamber 100A according to the present embodiment. Particularly,FIG. 5 illustrates a cross section of theheating cooking chamber 100A taken along a plane orthogonal to the left-right direction. - As illustrated in
FIG. 5 , the pull-out typeheating cooking apparatus 100 further includes a firstair sending unit 14. The firstair sending unit 14 circulates first air F1 between the inside of theheating cooking chamber 100A and the inside of a firstair sending chamber 14A. - Specifically, the first
air sending unit 14 includes a firstsuction hole portion 14D, a first blow-outhole portion 14C, and afirst partitioning member 14B. The firstsuction hole portion 14D is positioned in the third direction D3 with respect to theaccommodation space 120. The first blow-outhole portion 14C is positioned in the third direction D3 with respect to theaccommodation space 120. More specifically, the firstair sending unit 14 is positioned above theheating cooking chamber 100A with thetop wall 1C interposed therebetween. The firstsuction hole portion 14D is positioned above theheating cooking chamber 100A. The first blow-outhole portion 14C is positioned above theheating cooking chamber 100A. - The first
air sending unit 14 suctions the first air F1 in theheating cooking chamber 100A through the firstsuction hole portion 14D and blows the first air F1 into theheating cooking chamber 100A through the first blow-outhole portion 14C. Particularly, the firstair sending unit 14 suctions the first air F1 from a predetermined region EA in theaccommodation space 120 and blows the first air F1 into the predetermined region EA in theaccommodation space 120. The predetermined region EA is, for example, a center region within theaccommodation space 120. For example, a center portion of the object H to be heated is disposed in the predetermined region EA. - As described above, according to the pull-out type
heating cooking apparatus 100, the firstsuction hole portion 14D and the first blow-outhole portion 14C are positioned in the same third direction D3 with respect to theaccommodation space 120, which reduces the distance between the firstsuction hole portion 14D and the first blow-outhole portion 14C. As a result, a circulation path of the first air F1 is also reduced. Thus, the predetermined region EA within theheating cooking chamber 100A can be heated in a short period of time. - Furthermore, the first
suction hole portion 14D and the first blow-outhole portion 14C are positioned above theheating cooking chamber 100A. When theheating cooking chamber 100A has a rectangular parallelepiped shape having a short distance between thetop wall 1C and thebottom wall 1D and the predetermined region EA is a center region within theaccommodation space 120, a distance between the firstsuction hole portion 14D and the predetermined region EA and a distance between the first blow-outhole portion 14C and the predetermined region EA are reduced. As a result, the predetermined region EA within theheating cooking chamber 100A can be heated by the firstair sending unit 14 within a shorter period of time. - Particularly, the first
air sending unit 14 further includes the firstair sending chamber 14A, afirst heater 141, a firstcentrifugal fan 142, afirst drive unit 143, and afirst energization unit 144. The firstcentrifugal fan 142 is an example of a “first fan”. The firstair sending chamber 14A is, for example, a box-like member. The firstcentrifugal fan 142 includes a plurality of blades. - The
first heater 141 and the firstcentrifugal fan 142 are accommodated in the firstair sending chamber 14A. In other words, thefirst heater 141 is positioned above theheating cooking chamber 100A. Thefirst heater 141 heats the first air F1 in the firstair sending chamber 14A. Specifically, the shape of thefirst heater 141 is a circular ring when viewed from the upper side to the lower side. Further, thefirst heater 141 is disposed along the outer circumference of the firstcentrifugal fan 142. As a result, the firstcentrifugal fan 142 blows the first air F1 heated by thefirst heater 141 into theheating cooking chamber 100A. Thus, the predetermined region EA within theheating cooking chamber 100A can be heated in a short period of time. - The
first drive unit 143 is positioned outside the firstair sending chamber 14A. Thefirst drive unit 143 is connected to an external power source. Thefirst drive unit 143 drives the firstcentrifugal fan 142. Thefirst drive unit 143 includes, for example, a motor. Thefirst drive unit 143 is controlled by thecontrol unit 5. - The
first energization unit 144 is positioned outside the firstair sending chamber 14A. Thefirst energization unit 144 is connected to the external power source. Thefirst energization unit 144 energizes thefirst heater 141. The energizedfirst heater 141 generates heat. Thefirst drive unit 143 is controlled by thecontrol unit 5. Thefirst energization unit 144 includes, for example, a switch. - Next, the
first partitioning member 14B according to the present embodiment will be further described with reference toFIG. 5 andFIG. 6 .FIG. 6 is a diagram illustrating thefirst partitioning member 14B according to the present embodiment. - As illustrated in
FIG. 5 andFIG. 6 , thefirst partitioning member 14B is positioned above theaccommodation space 120. Specifically, thefirst partitioning member 14B is positioned between the firstair sending chamber 14A and theheating cooking chamber 100A. Thefirst partitioning member 14B is, for example, a plate-like member made of a metal. The shape of thefirst partitioning member 14B is, for example, a square shape when viewed from the upper side to the lower side. Thefirst partitioning member 14B is disposed in a substantially center portion of thetop wall 1C. The firstsuction hole portion 14D and the first blow-outhole portion 14C are disposed in thefirst partitioning member 14B. Thus, the firstsuction hole portion 14D and the first blow-outhole portion 14C can be easily disposed above theaccommodation space 120. - More specifically, the first
suction hole portion 14D is, for example, a set of a plurality of punched holes. Similarly, the first blow-outhole portion 14C is, for example, a set of a plurality of punched holes. The punched holes are examples of suction holes and blow-out holes. Each of the punched holes has, for example, a circular shape. The diameter of each of the punched holes of the firstsuction hole portion 14D and the first blow-outhole portion 14C is, for example, 3.4 mm. Thus, each of the firstsuction hole portion 14D and the first blow-outhole portion 14C has a small size. As a result, it is possible to prevent a tool or the like from being caught in the firstsuction hole portion 14D and the first blow-outhole portion 14C when theheating cooking chamber 100A is cleaned. - More specifically, the first blow-out
hole portion 14C surrounds the firstsuction hole portion 14D. Specifically, the firstsuction hole portion 14D is positioned at the center portion of thefirst partitioning member 14B. The set of the plurality of punched holes of the firstsuction hole portion 14D has, for example, a circular shape. On the other hand, the first blow-outhole portion 14C is formed along the outer circumference of the firstsuction hole portion 14D. The set of the plurality of punched holes of the first blow-outhole portion 14C has, for example, an annular shape. - The first
centrifugal fan 142 opposes theheating cooking chamber 100A through thefirst partitioning member 14B. The firstsuction hole portion 14D opposes the firstcentrifugal fan 142. - Here, flow of the first air F1 will be described in detail. First, the
first drive unit 143 drives the firstcentrifugal fan 142, and thefirst energization unit 144 energizes thefirst heater 141. The firstcentrifugal fan 142 suctions the first air F1 in theheating cooking chamber 100A into the firstair sending chamber 14A through the firstsuction hole portion 14D. The first air F1 taken into the firstair sending chamber 14A is heated by thefirst heater 141. The firstcentrifugal fan 142 blows the first air F1 in the firstair sending chamber 14A into theheating cooking chamber 100A through the first blow-outhole portion 14C. - The first air F1 blown into the
heating cooking chamber 100A moves downward. Thereafter, the first air F1 that has reached the peripheral region of the predetermined region EA in theheating cooking chamber 100A moves, for example, toward the center region of the predetermined region EA and moves upward so that the movement direction of the first air F1 is reversed. That is, the predetermined region EA is disposed below thefirst heater 141 and the firstcentrifugal fan 142. The first air F1 moving upward moves within theheating cooking chamber 100A. Thereafter, the first air F1 is taken into the firstair sending chamber 14A again from the firstsuction hole portion 14D. In this manner, the firstair sending unit 14 circulates the first air F1 between the firstair sending chamber 14A and the predetermined region EA in theheating cooking chamber 100A. - As described above, according to the pull-out type
heating cooking apparatus 100, the first blow-outhole portion 14C surrounds the firstsuction hole portion 14D, and thus it is possible to more uniformly heat the predetermined region EA in theheating cooking chamber 100A. - Next, a second
air sending unit 13 according to the present embodiment will be further described with reference toFIG. 7 .FIG. 7 is a diagram illustrating a schematic cross section of theheating cooking chamber 100A according to the present embodiment. Particularly,FIG. 7 illustrates a cross section of theheating cooking chamber 100A taken along a plane orthogonal to the left-right direction. - As illustrated in
FIG. 7 , the pull-out typeheating cooking apparatus 100 further includes the secondair sending unit 13. The secondair sending unit 13 circulates second air F2 between the inside of theheating cooking chamber 100A and the inside of a secondair sending chamber 13A. - Specifically, the second
air sending unit 13 includes a secondsuction hole portion 13D, a second blow-outhole portion 13C, and asecond partitioning member 13B. The secondsuction hole portion 13D is positioned in a direction opposite to the first direction D1 with respect to theaccommodation space 120. The second blow-outhole portion 13C is positioned in the direction opposite to the first direction D1 with respect to theaccommodation space 120. Specifically, the secondair sending unit 13 is positioned on a rear side of theheating cooking chamber 100A with theback wall 1E interposed therebetween. The rear side of theheating cooking chamber 100A is an example of a “predetermined side of theheating cooking chamber 100A”. The secondsuction hole portion 13D is positioned on the rear side of theheating cooking chamber 100A. The second blow-outhole portion 13C is positioned on the rear side of theheating cooking chamber 100A. - The second
air sending unit 13 suctions the second air F2 in theheating cooking chamber 100A through the secondsuction hole portion 13D and blows the second air F2 into theheating cooking chamber 100A through the second blow-outhole portion 13C. Specifically, the secondair sending unit 13 suctions the second air F2 from a center portion in theheating cooking chamber 100A and blows the second air F2 to a peripheral edge portion in theheating cooking chamber 100A. - Particularly, the second
air sending unit 13 further includes the secondair sending chamber 13A, asecond heater 131, a secondcentrifugal fan 132, asecond drive unit 133, and asecond energization unit 134. The secondcentrifugal fan 132 is an example of a “second fan”. The secondair sending chamber 13A is, for example, a box-like member. The secondcentrifugal fan 132 includes a plurality of blades. - The
second heater 131 and the secondcentrifugal fan 132 are accommodated in the secondair sending chamber 13A. In other words, thesecond heater 131 is disposed on the rear side of theheating cooking chamber 100A. Thesecond heater 131 heats the second air F2 in the secondair sending chamber 13A. Specifically, the shape of thesecond heater 131 is a circular ring when viewed from the front side to the rear side. Further, thesecond heater 131 is disposed along the outer circumference of the secondcentrifugal fan 132. As a result, the secondcentrifugal fan 132 blows the second air F2 heated by thesecond heater 131 into theheating cooking chamber 100A. Thus, the entire inside of theheating cooking chamber 100A can be heated in a short period of time. - The
second drive unit 133 is positioned outside the secondair sending chamber 13A. Thesecond drive unit 133 is connected to the external power source. Thesecond drive unit 133 drives the secondcentrifugal fan 132. Thesecond drive unit 133 includes, for example, a motor. Thesecond drive unit 133 is controlled by thecontrol unit 5. - The
second energization unit 134 is positioned outside the secondair sending chamber 13A. Thesecond energization unit 134 is connected to the external power source. Thesecond energization unit 134 energizes thesecond heater 131. The energizedsecond heater 131 generates heat. Thesecond energization unit 134 is controlled by thecontrol unit 5. Thesecond energization unit 134 includes, for example, a switch. - In the present embodiment, the number of blades of the second
centrifugal fan 132 is smaller than the number of blades of the firstcentrifugal fan 142. The size of the secondcentrifugal fan 132 is greater than the size of the firstcentrifugal fan 142. Particularly, the diameter of the secondcentrifugal fan 132 is greater than the diameter of the firstcentrifugal fan 142. Further, the thickness of the secondcentrifugal fan 132 along the rotation axis is greater than the thickness of the firstcentrifugal fan 142 along the rotation axis. Accordingly, the size of the secondair sending chamber 13A is greater than the size of the firstair sending chamber 14A. In particular, the thickness of the secondair sending chamber 13A along the rotation axis is greater than the thickness of the firstair sending chamber 14A along the rotation axis. As a result, the predetermined region EA in theheating cooking chamber 100A can be heated in a short period of time by the firstair sending unit 14, and the entire inside of theheating cooking chamber 100A can be heated by the secondair sending unit 13. - Next, the
second partitioning member 13B according to the present embodiment will be further described with reference toFIG. 7 andFIG. 8 .FIG. 8 is a diagram illustrating thesecond partitioning member 13B according to the present embodiment. - As illustrated in
FIG. 7 andFIG. 8 , thesecond partitioning member 13B is positioned on the rear side of theaccommodation space 120. Specifically, thesecond partitioning member 13B is positioned between the secondair sending chamber 13A and theheating cooking chamber 100A. Thesecond partitioning member 13B is, for example, a plate-like member made of a metal. The shape of thesecond partitioning member 13B is, for example, a rectangular shape when viewed from the front side to the rear side. Thesecond partitioning member 13B is disposed on substantially the entire surface of theback wall 1E. The secondsuction hole portion 13D and the second blow-outhole portion 13C are disposed in thesecond partitioning member 13B. Thus, the secondsuction hole portion 13D and the second blow-outhole portion 13C can be easily disposed behind theaccommodation space 120. - More specifically, the second
suction hole portion 13D is, for example, a set of a plurality of punched holes. Similarly, the second blow-outhole portion 13C is, for example, a set of a plurality of punched holes. The punched holes are examples of suction holes and blow-out holes. Each of the punched holes has, for example, a circular shape. The diameter of each of the punched holes of the secondsuction hole portion 13D and the second blow-outhole portion 13C is, for example, 3.4 mm. Thus, each of the secondsuction hole portion 13D and the second blow-outhole portion 13C has a small size. As a result, it is possible to prevent a tool or the like from being caught in the secondsuction hole portion 13D and the second blow-outhole portion 13C when theheating cooking chamber 100A is cleaned. - More specifically, the second blow-out
hole portion 13C is disposed along the outer circumference of thesecond partitioning member 13B. The distance between the second blow-outhole portion 13C and the secondsuction hole portion 13D is greater than the distance between the first blow-outhole portion 14C and the firstsuction hole portion 14D. Specifically, the secondsuction hole portion 13D is positioned at the center portion of thesecond partitioning member 13B. The set of the plurality of punched holes of the secondsuction hole portion 13D has, for example, a circular shape. On the other hand, the second blow-outhole portion 13C is positioned at a peripheral edge portion along the edge of theback wall 1E. Specifically, the second blow-outhole portion 13C includes a first peripheral edge blow-out hole portion 13C1A, a second peripheral edge blow-out hole portion 13C1B, a third peripheral edge blow-out hole portion 13C1C, and a fourth peripheral edge blow-out hole portion 13C1D. When the pull-out typeheating cooking apparatus 100 is viewed from the front, the first peripheral edge blow-out hole portion 13C1A is positioned in an upper right region of theback wall 1E. The second peripheral edge blow-out hole portion 13C1B is positioned in a lower right region of theback wall 1E. The third peripheral edge blow-out hole portion 13C1C is positioned in a lower left region of theback wall 1E. The fourth peripheral edge blow-out hole portion 13C1D is positioned in an upper left region of theback wall 1E. Note that the distance between the blow-out hole portion and the suction hole portion refers to the distance between the center of the suction hole portion and the blow-out hole farthest from the center of the suction hole portion. - The second
centrifugal fan 132 opposes theheating cooking chamber 100A through thesecond partitioning member 13B. The secondsuction hole portion 13D opposes the secondcentrifugal fan 132. - Now, the flow of the second air F2 will be described in detail. First, the
second drive unit 133 drives the secondcentrifugal fan 132, and thesecond energization unit 134 energizes thesecond heater 131. The secondcentrifugal fan 132 suctions the second air F2 in theheating cooking chamber 100A into the secondair sending chamber 13A through the secondsuction hole portion 13D. The second air F2 taken into the secondair sending chamber 13A is heated by thesecond heater 131. The secondcentrifugal fan 132 blows the second air F2 in the secondair sending chamber 13A into theheating cooking chamber 100A through the second blow-outhole portion 13C. - The second air F2 blown into the
heating cooking chamber 100A mainly moves forward along theright wall 1A and theleft wall 1B. Thereafter, the second air F2 that has reached the rear face of thelid portion 21 moves rearward such that the movement direction of the second air F2 is reversed. The second air F2 moving rearward moves within theheating cooking chamber 100A. Thereafter, the second air F2 is taken into the secondair sending chamber 13A again from the secondsuction hole portion 13D. In this manner, the secondair sending unit 13 circulates the second air F2 between the inside of the secondair sending chamber 13A and the inside of theheating cooking chamber 100A. - As described above, according to the pull-out type
heating cooking apparatus 100, the second blow-outhole portion 13C is disposed along the outer circumference of thesecond partitioning member 13B, and thus the entire inside of theheating cooking chamber 100A can be more uniformly heated by the secondair sending unit 13. - As illustrated again in
FIG. 7 andFIG. 8 , the pull-out typeheating cooking apparatus 100 further includes agrill unit 16. Specifically, thegrill unit 16 includes aheating cooking heater 161 and anenergization unit 162. Theheating cooking heater 161 is an example of a “third heater”. Theheating cooking heater 161 is positioned in the third direction D3 with respect to theaccommodation space 120 and heats the object H to be heated. Particularly, theheating cooking heater 161 is positioned at an upper portion inside theheating cooking chamber 100A. As a result, the object H to be heated can be heated and cooked by transmitting heat generated by theheating cooking heater 161 to the object H to be heated. Particularly, theheating cooking heater 161 has a substantial U-shape when viewed from the upper side to the lower side. In the present embodiment, three of thegrill units 16 are disposed. Theheating cooking heater 161 is, for example, a sheathed heater. - The
energization unit 162 is positioned outside theleft wall 1B. Theenergization unit 162 is connected to the external power source. Theenergization unit 162 energizes theheating cooking heater 161. The energizedheating cooking heater 161 generates heat. Theenergization unit 162 is controlled by thecontrol unit 5. Theenergization unit 162 includes, for example, a switch. - A configuration of the pull-out type
heating cooking apparatus 100 will be described in detail with reference toFIG. 9 .FIG. 9 is a block diagram illustrating a configuration of the pull-out typeheating cooking apparatus 100 according to the present embodiment. As illustrated inFIG. 9 , thecontrol unit 5 further includes athermistor 51. - The
thermistor 51 is an example of a “temperature detection unit”. Thethermistor 51 detects the temperature in theheating cooking chamber 100A. Thethermistor 51 may be disposed in theheating cooking chamber 100A or may be disposed in the firstair sending chamber 14A. Thethermistor 51 is connected to thecontrol unit 5. Thethermistor 51 outputs a detection result to thecontrol unit 5 at predetermined time intervals. Specifically, thecontrol unit 5 calculates the temperature of air in the predetermined region EA in theheating cooking chamber 100A based on the detection result of thethermistor 51. - The
control unit 5 controls thefirst drive unit 143, thesecond drive unit 133, thefirst energization unit 144, thesecond energization unit 134, theenergization unit 162, thedrive motor 41, theoperation panel 3, and thestorage unit 6 by executing control programs stored in thestorage unit 6. Specifically, thecontrol unit 5 controls thefirst drive unit 143, thesecond drive unit 133, thefirst energization unit 144, thesecond energization unit 134, and theenergization unit 162 based on the detection result of thethermistor 51. As a result, thecontrol unit 5 can control thefirst drive unit 143, thesecond drive unit 133, thefirst energization unit 144, thesecond energization unit 134, and theenergization unit 162 at an appropriate timing. - Particularly, in the pull-out type
heating cooking apparatus 100, a “cooking process”, a “preheating process”, and a “heat retaining process” are executed when a predetermined object H to be heated is heated and cooked. - Next, the “cooking process” according to the present embodiment will be further described with reference to
FIG. 10 .FIG. 10 is a diagram illustrating a schematic cross section of theheating cooking chamber 100A according to the present embodiment. Particularly,FIG. 10 illustrates a cross section of theheating cooking chamber 100A in which the “cooking process” is executed. - As illustrated in
FIG. 10 , the “cooking process” indicates heating and cooking the object H to be heated in a state where the temperature in theheating cooking chamber 100A is substantially the same as a threshold temperature. The threshold temperature is set by a user or calculated by thecontrol unit 5 based on the type of the object H to be heated, a table, and the like. Specifically, thesecond drive unit 133 drives the secondcentrifugal fan 132. In addition, thesecond energization unit 134 energizes thesecond heater 131 and stops the energization of thesecond heater 131. Further, theenergization unit 162 energizes theheating cooking heater 161. As a result, the object H to be heated is heated and cooked by transmitting heat generated by theheating cooking heater 161 to the object H to be heated. - Next, with reference to
FIG. 11 andFIG. 12 , the “preheating process” according to the present embodiment will be further described.FIG. 11 is a time chart executed by thecontrol unit 5 according to the present embodiment. In the time chart ofFIG. 11 , the horizontal axis indicates time. In the time chart ofFIG. 11 , the vertical axis indicates whether each of thefirst drive unit 143, thesecond drive unit 133, thefirst energization unit 144, and thesecond energization unit 134 is in an ON state or an OFF state. The ON state indicates an energized state or a driven state. The OFF state indicates a non-energized state or a non-driven state. -
FIG. 12 is a graph showing a relationship between the temperature of the predetermined region EA included in theheating cooking chamber 100A according to the present embodiment and time. In the graph ofFIG. 12 , the horizontal axis represents time, the vertical axis represents temperature, and a temperature change of the predetermined region EA included in theheating cooking chamber 100A is indicated by a solid line LA. The temperature is a temperature calculated based on the detection result of thethermistor 51. - As shown in
FIGS. 11 and 12 , the “preheating process” indicates a process in which the temperature in theheating cooking chamber 100A exceeds a threshold temperature TT at least once before the object H to be heated is accommodated in theheating cooking chamber 100A. Specifically, the “preheating process” indicates a process in which the temperature of the predetermined region EA in theheating cooking chamber 100A exceeds the threshold temperature TT before the object H to be heated is accommodated in theheating cooking chamber 100A. - More specifically, the “preheating process” indicates a process in which after the temperature of the predetermined region EA in the
heating cooking chamber 100A reaches substantially the same temperature as the threshold temperature TT, a first predetermined period Δt1 or longer elapses from time t1 at which the temperature reaches the threshold temperature TT. The first predetermined period Δt1 indicates a period in which the temperature of thefirst heater 141 decreases to a first predetermined temperature or lower. The first predetermined temperature is an example of a “predetermined temperature”. The first predetermined temperature is a temperature for suppressing overheating of the firstair sending chamber 14A. The first predetermined period Δt1 and the first predetermined temperature are set in advance by a manufacturer or the like. - Further, in the “preheating process”, the
second heater 131 is energized at the time t1 at which the temperature of the predetermined region EA in theheating cooking chamber 100A becomes substantially the same as the threshold temperature TT, and the first predetermined period Δt1 or longer elapses from the time t1. As a result, the temperature of thesecond heater 131 rises. - For example, the user inputs execution of the “preheating process” to the
operation panel 3. When the execution of the “preheating process” is received, thecontrol unit 5 controls thefirst drive unit 143, thesecond drive unit 133, thefirst energization unit 144, and thesecond energization unit 134 based on the detection result of thethermistor 51. Specifically, at time to, thecontrol unit 5 drives thefirst drive unit 143 and energizes thefirst energization unit 144. In other words, as illustrated inFIG. 5 , the firstair sending unit 14 circulates the first air F1 between the firstair sending chamber 14A and the predetermined region EA in theheating cooking chamber 100A. As a result, the temperature of the predetermined region EA in theheating cooking chamber 100A rises. - Thereafter, when the
control unit 5 drives thefirst drive unit 143 and energizes thefirst energization unit 144, thecontrol unit 5 determines whether or not the temperature in theheating cooking chamber 100A is the threshold temperature TT or higher based on the detection result of thethermistor 51. When it is determined that the temperature of the predetermined region EA in theheating cooking chamber 100A is not the threshold temperature TT or higher, thecontrol unit 5 continues to drive thefirst drive unit 143 and energize thefirst energization unit 144. On the other hand, when it is determined that the temperature of the predetermined region EA in theheating cooking chamber 100A is the threshold temperature TT or higher, thecontrol unit 5 stops driving thefirst drive unit 143 and energizes thesecond energization unit 134. As a result, the temperature of the predetermined region EA in theheating cooking chamber 100A exceeds the threshold temperature TT. - The
control unit 5 stops energization of thefirst energization unit 144, and stops driving of thefirst drive unit 143 at time t2 at which the first predetermined period Δt1 elapses from the time t1 at which thesecond energization unit 134 is energized. - Further, the
control unit 5 stops energization of thefirst energization unit 144 and drives thesecond drive unit 133 at time t4 at which a third predetermined period Δt3 elapses from the time t1 at which thesecond energization unit 134 is energized. The third predetermined period Δt3 is longer than the first predetermined period Δt1. The third predetermined period Δt3 indicates a period during which the temperature of thesecond heater 131 rises to a second predetermined temperature or higher. The second predetermined temperature indicates a temperature for suppressing overheating of the secondair sending chamber 13A. The third predetermined period Δt3 and the second predetermined temperature are set in advance by a manufacturer or the like. In other words, as illustrated inFIG. 7 , the secondair sending unit 13 circulates the second air F2 between the inside of the secondair sending chamber 13A and the inside of theheating cooking chamber 100A. As a result, the temperature in the entireheating cooking chamber 100A becomes substantially the same as the threshold temperature TT. - In addition, the
control unit 5 stops energization of thefirst energization unit 144, and makes a notification of the completion of the preheating process at time t3 at which the second predetermined period Δt2 or longer elapses from the time t1 at which thesecond energization unit 134 is energized. In other words, thecontrol unit 5 stops energization of thefirst heater 141 and energizes thesecond heater 131 before the notification of the completion of the preheating process. For example, thecontrol unit 5 notifies the completion of the preheating process by sound or video. As a result, the user accommodates the object H to be heated in theheating cooking chamber 100A. Theheating cooking chamber 100A executes the “cooking process”. - As described above, the
control unit 5 stops energization of thefirst heater 141 and energizes thesecond heater 131 before the notification of the completion of the preheating process, which makes it possible to start heating and cooking of the object H to be heated in a state where the temperature of thesecond heater 131 has risen. As a result, the cooking period for heating and cooking the object H to be heated can be shortened. For example, heating and cooking of the object H to be heated can be started in a state where the temperature in the entireheating cooking chamber 100A has risen. - In addition, the
control unit 5 stops energization of thefirst energization unit 144 and stops driving of thefirst drive unit 143 at the time t2 at which the first predetermined period Δt1 elapses from the time t1 at which thesecond energization unit 134 is energized, and thus, the temperature of thefirst heater 141 decreases to the first predetermined temperature or lower. As a result, it is possible to suppress overheating of the firstair sending chamber 14A. - Particularly, the
control unit 5 stops energization of thefirst energization unit 144 and makes a notification of the completion of the preheating process at the time t3 at which a second predetermined period Δt2 elapses from the time t1 at which thesecond energization unit 134 is energized. The second predetermined period Δt2 is a period during which the temperature in theheating cooking chamber 100A decreases to substantially the same temperature as the threshold temperature TT. A length of the second predetermined period Δt2 is preferably equal to or longer than a length of the first predetermined period Δt1 and equal to or shorter than a length of the third predetermined period Δt3. The second predetermined period Δt2 is set in advance by a manufacturer or the like. As a result, it is possible to start heating and cooking the object H to be heated in a state where the temperature in theheating cooking chamber 100A has risen in a short period of time. - Furthermore, the
control unit 5 drives thesecond drive unit 133 after the notification of the completion of the preheating process. As a result, it is possible to stabilize determination of the threshold temperature TT at the notification time point. In addition, it is possible to suppress overheating of thesecond heater 131. - More particularly, in the pull-out type
heating cooking apparatus 100, the “heat retaining process” is further executed. The “heat retaining process” indicates that the temperature in theheating cooking chamber 100A is maintained to be substantially the same as the threshold temperature TT after the “preheating process” is executed. Specifically, thecontrol unit 5 controls thesecond energization unit 134. More specifically, thecontrol unit 5 energizes thesecond energization unit 134 or stops energization of thesecond energization unit 134. As a result, the user does not need to accommodate the object H to be heated in theheating cooking chamber 100A immediately after being notified of the completion of the preheating process. - In addition, in the pull-out type
heating cooking apparatus 100, when thelid portion 21 is pulled out during the execution of the “cooking process”, the “preheating process”, or the “heat retaining process”, energization of thefirst energization unit 144 and energization of thesecond energization unit 134 are stopped. As a result, it is possible to inhibit hot air from flowing out toward the user who has opened the inside of theheating cooking chamber 100A. - Next, a cooking method by the pull-out type
heating cooking apparatus 100 according to the present embodiment will be described with reference toFIG. 13 .FIG. 13 is a flowchart for explaining the cooking method by the pull-out typeheating cooking apparatus 100. - As illustrated in
FIG. 13 , in step S101, thecontrol unit 5 drives the firstcentrifugal fan 142 and energizes thefirst heater 141. - Next, in step S102, the
control unit 5 determines whether or not the temperature in theheating cooking chamber 100A is the threshold temperature TT or higher. In a case where thecontrol unit 5 determines in step S102 that the temperature in theheating cooking chamber 100A is not the threshold temperature TT or higher, the process returns to step S102. - On the other hand, in a case where the
control unit 5 determines in step S102 that the temperature in theheating cooking chamber 100A is the threshold temperature TT or higher, the process proceeds to step S103. In step S103, thecontrol unit 5 stops energization of thefirst heater 141 and energizes thesecond heater 131. - Next, in step S104, the
control unit 5 stops driving of the firstcentrifugal fan 142. - Next, in step S105, the
control unit 5 makes a notification of completion of the preheating process. - Next, in step S106, the
control unit 5 drives the secondcentrifugal fan 132. - Next, in step S107, the
control unit 5 determines whether or not the object H to be heated is accommodated in theheating cooking chamber 100A. In a case where thecontrol unit 5 determines in step S107 that the object H to be heated is not accommodated in theheating cooking chamber 100A, the process proceeds to step S108. On the other hand, when thecontrol unit 5 determines in step S107 that the object H to be heated is accommodated in theheating cooking chamber 100A, the process proceeds to step S109. - Next, in step S108, the
control unit 5 repeats energizing thesecond heater 131 and stopping the energization of thesecond heater 131. The process returns to step 7. - Next, in step S109, the
control unit 5 executes the “cooking process”. Then, the cooking method ends. - As described above, the cooking process is executed after the preheating process is executed, which makes it possible to shorten the cooking period for heating and cooking the object H to be heated.
