As shown in FIG. 10, the heating cooker 10 includes a control device 50, which includes a drain valve 17, a heater 25, a convection fan 26, a temperature sensor 27, a steam generator 30, a pump 42, and a water supply. It is connected to the valve 44. The control device 50 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 50 includes a cooking program for cooking the ingredients in the kitchen 20 and a cleaning program for cleaning the inside of the kitchen 20 in the ROM. The cooking program consists of a hot air mode cooking program in which a heater 25 and a convection fan 26 are operated to heat and cook foods by convection hot air, and a convection fan 26 and a steam generator 30 are operated to operate a convection steam containing hot air. 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 high-temperature hot air containing confluent steam by operating the heater 25, convection fan 26, and steam generator 30. It has a cooking program. Each of the above cooking programs that stores the set temperature, steam amount, and cooking time in the cooking cabinet 20 according to the cooking of foodstuffs is preset in the ROM, and in the cooking cabinet 20 according to the user's needs. It is possible to set each cooking program with the set temperature, steam amount and cooking time. In addition, the cleaning program executes one cleaning mode in which cleaning water containing detergent is circulated while being sprayed, and three rinsing modes (multiple times) in which cleaning water containing detergent is circulated while being sprayed. It is a thing.

When, for example, a combination mode cooking program of a cooking program is executed, the air in the cooking chamber 20 becomes hot air and circulates due to the operation of the heater 25 and the convection fan 26, and steam is steamed from the steam generator 30 into the cooking chamber 20. Is supplied, and the foodstuffs housed in the kitchen 20 are cooked by hot air containing steam. At this time, the oil contained in the food material is scattered in the cooking chamber 20 together with the convected hot air, and the oil content adheres to each wall of the cooking chamber 20, the partition plate 23, the support frame 24, and the like. In this type of cooking apparatus 10, it is desirable to keep the inside of the cooking chamber 20 hygienic at all times, so it is preferable to wash the cooking chamber 20 every day, for example, when it is used. For this purpose, the cooking device 10 has a cleaning program that automatically cleans the inside of the cooking chamber 20.

When cleaning the inside of the cooking chamber, the cleaning program is executed with a cube-shaped detergent (solid detergent) placed on the upper side of the drainage plate 20d provided in the drainage port 20c of the cooking chamber 20. The washing program performs a washing mode of washing with washing water containing detergent and a washing mode of rinsing with washing water containing no detergent three times. When the cleaning mode is started, the drain valve 17 is closed and the water supply valve 44 is opened for a predetermined time, so that cleaning water can be stored in the drain tank 14. When the washing water is stored in the drainage tank 14, the steam generator 30 is operated to supply steam into the cooking chamber 20 to supply oil and the like adhering to the peripheral wall of the cooking chamber 20. It is preferable to make the dirt float.

When the pump 42 is operated after the washing water is stored in the drain tank 14, the washing water stored in the drain tank 14 is sent to the washing nozzle 40 through the washing water supply pipe 41. The washing water is sprayed over a wide range in the front-rear direction from the injection port 40b of the washing nozzle 40 toward the side portion of the storage chamber 21 of the cooking chamber 20 opposite to the heating chamber 22. Further, since the injection port 40b is inclined upward toward the ceiling wall of the cooking cabinet 20, the washing water blown out from the injection port 40b is also sprayed on the ceiling wall of the cooking cabinet 20. The washing water sprayed from the injection port 40b flows down from the ceiling wall of the cooking chamber 20 along the peripheral wall. The washing water that has flowed down the peripheral wall of the cooking chamber 20 returns to the drainage tank 14 from the drainage port 20c through the first drainage pipe 16. The washing water returned to the drainage tank 14 is sent to the washing nozzle 40 again by the pump 42, and the washing water circulates between the cooking chamber 20 and the drainage tank 14. At this time, the detergent placed on the upper side of the drainage plate 20d becomes soluble in the washing water, and the washing water contains the detergent.

Also, when the cleaning program is being executed, the heater 25 and the convection fan 26 are operated. The cleaning water ejected from the injection port 40b of the cleaning nozzle 40 is further sprayed to every corner of the peripheral wall of the cooking chamber 20 by the air convected by the convection fan 26. That is, in the cooking chamber 20, the air in the storage chamber 21 is sucked into the heating chamber 22 by the convection fan 26 through the suction port 23a, and the sucked air passes from the heating chamber 22 to the storage chamber 21 through the ventilation space 23b. The air sent and in the cooking chamber 20 is convected between the storage chamber 21 and the heating chamber 22. The washing water sprayed from the injection port 40b toward the right side of the cooking cabinet 20 is sprayed to every corner of the peripheral wall of the cooking cabinet 20 by the convective air.

Further, since the heater 25 is also operated at the same time as the convection fan 26 is operated, the air convection in the cooking chamber 20 is heated, and the heated air uses the cleaning water sprayed from the cleaning nozzle 40 into the cooking chamber 20. It will warm up. In this way, by operating the heater 25 and the convection fan 26 while executing the cleaning program, the cleaning water ejected from the injection port 40b of the cleaning nozzle 40 becomes a high temperature state in which oil stains can be easily removed. , The peripheral wall of the cooking cabinet 20, the partition plate 23, and the support frame 24 can be sprayed to every corner, and it is possible to easily remove the oil stains adhering to the peripheral wall of the cooking cabinet 20 and the like. Further, the convection fan 26 is rotated alternately in the forward direction and the reverse direction to change the flow of the convection air in the cooking chamber 20. By doing so, the cleaning water ejected from the injection port 40b of the cleaning nozzle 40 is stored in the kitchen due to the air flow that changes when the convection fan 26 is rotated in the forward direction and in the reverse direction. It is designed to be sprayed to every corner of 20. When the cleaning mode of the cleaning program is executed for a predetermined time, the operations of the heater 25, the convection fan 26, and the pump 42 are stopped, the drain valve 17 is opened, and the cleaning water containing the detergent in the drain tank 14 is drained.

When the cleaning mode of the cleaning program is finished, the rinsing mode is executed. In the rinsing mode, the drain valve 17 is closed and the water supply valve 44 is opened for a predetermined time so that the washing water for rinsing can be stored in the drain tank 14. After that, when the pump 42 is operated, the washing water stored in the drain tank 14 is sent to the washing nozzle 40 through the washing water supply pipe 41, and the injection port 40b of the washing nozzle 40 is similar to the washing mode described above. The washing water spouted from the kitchen 20 can be sprayed to every corner of the peripheral wall of the kitchen 20, the partition plate 23, and the support frame 24, and the washing water containing the detergent sprayed in the washing mode can be washed away. .. Even in this rinsing mode, the heater 25 and the convection fan 26 are operated, and the convection fan 26 is rotated alternately in the forward direction and the reverse direction. When the rinsing mode of the cleaning program is executed for a predetermined time, the operation of the heater 25, the convection fan 26, and the pump 42 is stopped, the drain valve 17 is opened, and the cleaning water used for rinsing in the drain tank 14 is drained. In this embodiment, the rinsing mode is set to a plurality of times and the washing program is completed three times.

In the cooking apparatus 10 configured as described above, the ceiling wall of the cooking cabinet 20 is provided with a cleaning nozzle 40 having an injection port 40b open toward the side and injecting cleaning water. Since the cleaning nozzle 40 is not provided with moving parts such as rotation, the cleaning nozzle 40 can be used even when the cleaning nozzle 40 is attached to the ceiling wall of the cooking cabinet 20 while cooking in the cooking cabinet 20. It was possible to prevent problems such as sticking due to oil stains and getting stuck.

Further, in this embodiment, the injection port 40b of the cleaning nozzle 40 has one side portion (left side portion of the cooking cabinet 20) on which the heater 25 and the convection fan 26 are arranged and the other side portion (cooking chamber 20) on the opposite side. It opens toward the right side of the). Further, the side opposite to the heating chamber 22 in which the heater 25 and the convection fan 26 of the cooking cabinet 20 are arranged is a storage chamber 21 for accommodating and cooking food, and the injection port 40b is directed to the right side of the storage chamber 21. Since the opening was made, it was possible to easily wash away the oil stains adhering to the storage chamber 21 of the cooking cabinet 20.

Further, the injection port 40b of the cleaning nozzle 40 may be opened toward one side where the heater 25 and the convection fan 26 are arranged. In this case, the washing water ejected from the injection port 40b is scattered by the convection fan 26 and is sprayed on the entire cooking chamber 20.

Further, the cleaning water ejected from the injection port 40b of the cleaning nozzle 40 is ejected toward the ceiling wall of the cooking chamber 20. As a result, the spouted washing water flows down from the ceiling wall of the kitchen along each side wall, and not only the washing water can be flowed to the entire cooking room 20, but also the ceiling wall of the cooking room 20 where dirt easily remains is washed. It seems that it can be easily washed off with water.

Further, the cleaning nozzle 40 uses a cylindrical member extending vertically downward from the ceiling wall of the kitchen 20, and the injection port 40b is on the side surface of the cleaning nozzle 40 on the opposite side (the other side) of the heating chamber 22. Since it was formed by a slit extending in the circumferential direction, the cleaning nozzle 40 could be manufactured by simple parts and easy processing. Further, since the injection port 40b is formed by a narrow slit, the washing water ejected from the injection port 40b is vigorously ejected in a wide range in the front-rear direction, and the washing water is spread all over the inside of the kitchen 20. It became possible to shed.

In the heating cooker 10 of this embodiment, when the washing water is sprayed by the injection port 40b of the washing nozzle 40, the convection fan 26 controls the air in the cooking chamber 20 to be convected. The injection port 40b of the cleaning nozzle 40 faces the opposite side of the heating chamber 22 of the cooking cabinet 20, and the cleaning water is ejected from the injection port 40b only to the opposite side of the heating chamber 22 by the convection fan 26. It can be scattered to the heating chamber 22 side by the convection air in the cooking chamber 20, and the dirt adhering to the peripheral wall in the cooking chamber 20 can be washed off with washing water to every corner. In this case, since the convection fan 26 is rotated alternately in the forward direction and the reverse direction, the washing water is driven by the air flow that changes when the convection fan 26 is rotated in the forward direction and the reverse direction. It became possible to scatter to every corner of the inside, and it became possible to wash off the dirt adhering to the peripheral wall in the kitchen 20 with washing water to every corner.

In this embodiment, a heater 25 and a convection fan 26 are provided on the left side portion of the cooking cabinet 20 as one side portion, and the injection port 40b of the cleaning nozzle 40 is directed toward the right side portion of the cooking cabinet 20 as the other side portion.
