The heater 25 is formed in an annular shape on the left wall of the cooking chamber 20. Further, a convection fan 26 is arranged inside the heater 25 formed in an annular shape. When the heater 25 and the convection fan 26 are operated, the air in the food storage chamber 21 is sent to the hot air generation chamber 22 through the suction port 23a, and the air blown outward from the convection fan 26 in the centrifugal direction is the hot air generation chamber 22. Inside, it is heated by the heater 25 to become hot air, and the heated hot air is sent to the food storage chamber 21 through the ventilation passage 23b between the partition plate 23 and each wall of the kitchen 20. An internal temperature sensor 27 is provided on the left wall of the cooking chamber 20, and the internal temperature sensor 27 detects the temperature inside the cooking chamber 20.

As shown in FIG. 8, the machine room 12 of the housing 11 is provided with a steam generator 30 that supplies steam into the cooking chamber 20. The steam generator 30 heats water by induction heating to generate steam, and is installed above the drainage tank 14 for draining drainage from the kitchen 20. The steam generator 30 includes a tubular steam generator 31 that stores water at a predetermined water level, a heating body that heats the water in the steam generator 31 (not shown), and a winding around the outer periphery of the steam generator 31. It is provided with an induction heating coil 32 that heats the heated body, and a steam delivery cylinder 33 that sends the steam generated in the steam generation container 31 to the kitchen 20. The steam delivery cylinder 33 is connected to a steam introduction port (not shown) formed on the left side wall of the cooking cabinet 20, and steam generated in the steam generation container 31 passes through the steam delivery cylinder 33 and is used in the cooking cabinet from the steam introduction port. Sent within 20.

As shown in FIG. 9, the cooking cooker 10 includes a control device 40, and the control device 40 is connected to a heater 25, a convection fan 26, an internal temperature sensor 27, a core temperature sensor 28, and a steam generator 30. Has been done. The control device 40 has a microcomputer (not shown), and the microcomputer includes a CPU, RAM, ROM, and a timer (all of which are not shown) connected via a bus.

The control device 40 includes a cooking program in which the ingredients in the kitchen 20 are cooked in the ROM. The cooking program consists of a hot air mode cooking program in which the heater 25 and the convection fan 26 are operated to heat and cook the ingredients by convection hot air, and the convection fan 26 and the steam generator 30 are operated to operate the hot air containing convection steam. There are three types of cooking programs: a steam mode cooking program that heats and cooks ingredients, and a combination mode cooking program that heats and cooks ingredients with hot air containing convected steam by operating the heater 25, convection fan 26, and steam generator 30. It has a cooking program. The ROM stores a cooking program in which the set temperature, the amount of steam, and the cooking time in the kitchen 20 are preset, and the user can store the set temperature, the amount of steam, and the cooking time of the cooking program 20 in the cooking program. It is possible to set.

Hot air mode of the cooking program When the cooking program is executed, the air in the food storage chamber 21 is sucked into the hot air generation chamber 22 through the suction port 23a by the operation of the heater 25 and the convection fan 26, and the sucked air. Is blown outward from the convection fan 26 in the centrifugal direction, the air blown outward in the centrifugal direction is heated when passing around the heater 25, and the heated air becomes hot air and passes through the ventilation passage 23b. It is sent to the food storage room 21. The air in the cooking chamber 20 is heated by the heater 25 in the process of circulating between the food storage chamber 21 and the hot air generating chamber 22 by the convection fan 26 to become hot air, which is convected in the cooking chamber 20 and stored in the cooking chamber 20. Ingredients are cooked by convection hot air.

Further, when the combination mode cooking program of the cooking program is executed, the air in the kitchen 20 is circulated between the food storage chamber 21 and the hot air generation chamber 22 by the convection fan 26, as in the case of executing the hot air mode cooking program. In the process of cooking, the food is heated by the heater 25 and becomes hot air to convection in the cooking chamber 20, and the steam is supplied from the steam generator 30 into the cooking chamber 20 so that the foodstuffs stored in the cooking chamber 20 are convected. It is cooked by hot air containing steam.

Each mode cooking program can confirm that the internal temperature of the food material detected by the core temperature sensor 28 has reached the set temperature inside the food material, and the temperature inside the food material detected by the core temperature sensor 28 reaches the set temperature. It is also possible to set the elapsed time since it arrived.

In each cooking program of the cooking device 10 configured as described above, the elapsed time from when the temperature inside the food material reaches the set temperature can be set by using the core temperature sensor 28. When executing a cooking program that measures the elapsed time from when the temperature inside the food material reaches the set temperature using the core temperature sensor 28, the temperature detection unit 28a of the core temperature sensor 28 is pierced into the food material. When executing a cooking program that does not use the core temperature sensor 28, the core temperature sensor 28 is held in the holder 24h of the front support column 24a of the right support frame 24 and housed in the right corner of the front part of the cooking cabinet 20.

In this cooking cooker 10, the holder 24h includes a lower holder 24i that holds the handle portion 28b of the core temperature sensor 28 under the front support column 24a of the right support frame 24, and a lower holder 24i of the front support column 24a. An upper holder 24j for holding the temperature detection unit 28a of the core temperature sensor 28 is provided on the upper side. In the core temperature sensor 28, the handle portion 28b is held by the lower holder 24i, the temperature detection portion 28a is held by the upper holder 24j, and the core temperature sensor 28 is held in an upright posture along the front support column 24a of the support frame 24. When not in use, it can be easily stored in the front part of the kitchen 20. Further, since the core temperature sensor 28 is housed with the temperature detection unit 28a standing upright so as to face upward, the electric wiring 28c extending from the side opposite to the temperature detection unit 28a of the handle portion 28b hangs down. Therefore, it was possible to prevent the electrical wiring 28c from being sandwiched between the opening 20c of the cooking cabinet 20 and the door 13.

Since the lower holder 24i is formed by bending a metal wire rod, the processing is easy. Since the lower holder 24i is provided so as to protrude forward from the front support column 24a and has a holding portion 24i1 opened on the front side for holding the handle portion 28b of the core temperature sensor 28 so as to be able to be taken in and out from the front side, the core temperature sensor The handle portion 28b of the core temperature sensor 28 can be easily attached to and detached from the lower holder 24i simply by moving the handle portion 28b of the 28 back and forth. Since the holding portion 24i1 is inclined so that the front portion is on the upper side, the handle portion 28b of the core temperature sensor 28 is held when the handle portion 28b of the core temperature sensor 28 is held by the lower holder 24i. It was possible to prevent it from slipping off the part 24i1. Further, since the holding portion 24i1 is open to the front side, even if the handle portion 28b is inserted into the holding portion 24i1, the electric wiring 28c will hang down as it is, and the electric wiring 28c will interfere with the loading and unloading of the tray. I was able to prevent it from becoming.

The lower holder 24i includes a leg portion 24i2 extending diagonally rearward and downward from the front end of the holding portion 24i1 to the front strut 24a side, and the rear portion of the holding portion 24i1 and the leg portion 24i2 are fixed to the front strut 24a. .. As a result, the lower holder 24i is fixed to the front support column 24a at two points above and below, and is firmly fixed to the front support column 24a.

The upper holder 24j is formed by bending a metal wire rod so that an opening 24j1 that opens downward is formed. Specifically, the upper holder 24j is formed by bending a metal wire rod into a U-shape that opens inside the cooking cabinet 20, and one end of the U-shaped metal wire rod in the longitudinal direction is the front portion of the front support column 24a. The other end of the U-shaped metal wire rod in the longitudinal direction is fixed to the rear part of the front support column 24a by welding, and an opening 24j1 that opens diagonally forward and downward between the front support column 24a is provided. I try to form it. Since the upper holder 24j is made by bending a metal wire and fixing both ends to the front and rear parts of the front support columns 24a and 24b by welding, the processing is easy and it is strong at two points on the front side support column 24a. It came to be fixed to. Further, since the upper holder 24j is formed with an opening 24j1 that opens diagonally forward and downward, the tip portion of the temperature detecting portion 28a of the core temperature sensor 28 can be easily inserted from below.

When the core temperature sensor 28 is not used, as shown in FIG. 10 (a), the tip of the temperature detection unit 28a is inserted into the opening 24j1 of the upper holder 24j from the lower side, and then in FIG. 10 (b). As shown, the handle portion 28b is simply inserted into the holding portion 24i1 from the front side and held. Further, when the core temperature sensor 28 is used, the handle portion 28b is simply pulled out to the front side while pulling out the tip portion of the temperature detection unit 28a downward from the opening 24j1 of the upper holder 24j, so that the core temperature sensor 28 is used. The 28 can be attached / detached at a position close to the opening 20a of the kitchen 20, and the core temperature sensor 28 can be attached / detached to / from the holder 24h without trouble. Further, as shown in FIGS. 7 and 10 (c), the holder 24h can hold two core temperature sensors 28.

Further, since the support frame 24 uses metal wires for the front and rear columns 24a and 24b and the five (plurality) rails 24f, the weight of the support frame 24 can be reduced and the support frame 24 can be processed. Has become easier. In particular, the support frame 24 of this embodiment uses metal wire rods in all parts including the front and rear columns 24a and 24b and the five (plurality) rails 24f, so that the support frame 24 The weight can be reduced, and the support frame 24 can be easily processed.

Further, when the tray containing the food is supported by the rail 24f, the load of the tray containing the food is applied to the rail 24f, but the rail 24f is directly fixed to the front and rear columns 24a and 24b. Therefore, the load of the tray can be received by the front and rear columns 24a and 24b. Further, since the front and rear columns 24a and 24b to which the load of the tray is applied are made of metal wire thicker than the rail 24f, the support frame 24 has the strength to support the tray without increasing the overall weight. This has made it possible to keep the cost of the support frame 24 low.

The distance between the left and right front columns 24a of the pair of left and right support frames 24 is wider than the width of the tray, and the distance between the left and right rear columns 24b is narrower than the width of the tray. By making the distance between the left and right front columns 24a of the pair of left and right support frames 24 wider than the width of the tray, it is possible to easily insert the tray from between the left and right front columns 24a along the rail 24f. By making the distance between the left and right rear columns 24b narrower than the width of the tray, the tray inserted toward the back side of the kitchen 20 along the rail 24f comes into contact with the left and right rear columns 24b. .. As described above, since it is not necessary to provide the support frame 24 with a stopper for preventing the tray from falling from the rear portion of the rail 24f, it is possible to prevent the cost of the support frame 24 from increasing.

The front studs 24a and the rear studs 24b are integrally connected by upper and lower connecting bars 24c and 24d fixed to the upper and lower portions, and the upper and lower connecting bars 24c and 24d have four (plural) extending vertically. The studs 24e1 to 24e4 are fixed. Three of these studs 24e1 to 24e4, 24e1 to 24e3 (at least one), are fixed to the front of the upper and lower connecting bars 24c, 24d. By doing so, when the tray is inserted into the back side along the rail 24f, even if the back side of the tray is likely to be tilted in the left-right direction, the back side of the tray is on the upper side and the lower side. Since the studs 24e1 to 24e3 provided at the front of the connecting bars 24c and 24d are restricted from shifting in the left-right direction, the tray can be easily inserted straight along the rail 24f. In this case, the three intervals Sa to Sc formed by the four studs are widened toward the rear. By doing so, many studs 24e1 to 24e3 are arranged in the front part of the upper and lower connecting bars 24c and 24d, and the back side of the tray is in front of the upper and lower connecting bars 24c and 24d. The studs 24e1 to 24e3, which are provided in many parts, further regulate the deviation in the left-right direction, making it easier for the tray to be inserted straight along the rail 24f. The number of studs is not limited to four, and at least one is fixed to the front of the upper and lower connecting bars 24c and 24d, and when the number of studs is three or more. The studs may be arranged so that the distance between the two or more studs is wider than the distance on the front side.

Further, the five rails 24f are made of a material harder than other parts of the support frame 24 including the front side and rear side columns 24a and 24b. The rail 24f is easily worn by sliding the tray back and forth, but the rail 24f is made of a harder material than the other parts of the support frame 24 including the front and rear columns 24a and 24b. It is possible to prevent the rail 24f from being locally scraped as compared with other parts, and it becomes possible to improve the durability of the support frame 24.

In the above embodiment, the holder 24h is provided on the front support column 24a of the support frame 24 on the right side, but the present invention is not limited to this, and the holder 24h is provided on the front support column 24a of the support frame 24 on the left side or both sides. It may be.
