Hereinafter, an embodiment of a heating cooker according to the present invention will be described with reference to the drawings.
(First embodiment)
As shown in FIGS. 1-3, the heating cooker 10 of 1st Embodiment has the cooking space 11a which accommodates and cooks a foodstuff, and the cooking chamber 11 which has the heating space 11b which sends hot air to this cooking space 11a, The blower fan 20, which is rotatably attached to one side wall of the cooking chamber 11 on the heating space 11 b side and blows air sucked from the center in the centrifugal direction to circulate the air in the cooking cabinet 11, From a heater 30 attached to the outer peripheral side of the blower fan 20 on one side wall of the heating space 11b and heating the inside of the cooking chamber 11, and from a steam inlet 11c formed on one side wall of the heating space 11b of the cooking chamber 11 A steam generator 40 that sends steam into the cooking chamber 11, and a temperature sensor that detects the temperature inside the cooking chamber 11 attached to a position on the outer peripheral side of the heater 30 on one side wall of the cooking space 11 on the heating space 11 b side. 0, and a control unit 60 for controlling the operation of heater 30 based on the temperature detected by the temperature sensor 50. In the heating cooker 10, the temperature sensor 50 is disposed downstream of the steam inlet 11 c in the blowing direction when the blower fan 20 is rotated, and the temperature is set on one side wall of the cooking chamber 11 on the heating space 11 b side. A shielding plate 51 is provided at a position of the sensor 50 on the steam inlet 11c side. Below, this heating cooker 10 is explained in full detail.

  The heating cooker 10 includes a cooking chamber 11, a blower fan 20, a heater 30, a steam generation device 40, a temperature sensor 50, and a control device 60 in a casing 10 a.

  The cooking chamber 11 is for containing and heating food, and has a box shape in which a part of the front surface is opened and the periphery is covered with a heat insulating material. A heat insulating door 12 having a heat-resistant glass window is provided at the opening on the front surface of the cooking chamber 11 so as to be freely opened and closed. The cooking chamber 11 includes a cooking space 11a for containing and cooking ingredients and a heating space 11b for sending hot air to the cooking space 11a. The cooking space 11a and the heating space 11b are partitioned by a fan cover 22 so as to allow ventilation. ing.

  The blower fan 20 circulates the air in the cooking cabinet 11, and a centrifugal fan such as a sirocco fan is used. The blower fan 20 is rotatably attached to the left side wall (one side wall) on the heating space 11b side of the cooking cabinet 11, and the blower fan 20 is driven from the cooking space 11a side by driving and rotating the fan motor 21. The sucked air is discharged in the centrifugal direction. The blower fan 20 of the present embodiment rotates counterclockwise when viewed from the right side wall side of the cooking chamber 11. The blower fan 20 is provided with a plate-like fan cover 22 on the air inlet side. The fan cover 22 prevents foreign matter from entering the blower fan 20 and has a large number of ventilation holes formed in the center. The air of the cooking space 11a is sent to the ventilation fan 20 through 22a. As described above, the fan cover 22 divides the cooking chamber 11 into the cooking space 11a and the heating space 11b, and from the blower fan 20 between the upper wall, the lower wall, the front wall, and the rear wall of the cooking chamber 11. It is attached with a gap that allows the air to pass through.

  The heater 30 heats the inside of the cooking chamber 11, and a known electric heater such as a sheathed heater is used. The heater 30 is annularly attached to the outer peripheral side of the blower fan 20 on the left side wall (one side wall) that is the heating space 11 b side of the cooking chamber 11. When the heater 30 is operated in a state where the air in the cooking chamber 11 is circulated by the blower fan 20, the blower fan 20 sucks the air in the cooking space 11 a and blows it in the centrifugal direction, and the blower fan 20 blows in the centrifugal direction. When passing through the heater 30 attached to the outer peripheral side, it is heated and becomes hot air, and this hot air is a space formed between the upper wall, lower wall, front wall and rear wall of the cooking chamber 11 and the fan cover 22. It sends to the cooking space 11a from the ventilation path which consists of.

  The steam generator 40 is for sending steam into the cooking chamber 11 and is provided in the casing 10 a at a position on the left side of the cooking chamber 11. The steam generation device 40 generates steam by heating a conductive heating body accommodated in a cylindrical evaporation container by electromagnetic induction heating. The steam delivery port of the steam generator 40 delivers steam to a steam inlet 11c formed at a position on the outer wall side of the heater 30 on the rear wall side upper part of the left side wall which is the heating space 11b side of the cooking chamber 11. It is connected via a tube. In a state where the blower fan 20 and the heater 30 are operated, the steam introduced from the steam introduction port 11 c is sent to the cooking space 11 a together with the hot air generated by the blower fan 20 and the heater 30.

  The temperature sensor 50 detects the temperature in the cooking chamber 11, and for example, a thermocouple is used. The temperature sensor 50 is attached to a position on the outer peripheral side of the heater 30 in the upper part on the front wall side of the left side wall (one side wall) on the cooking space 11 side. The temperature sensor 50 is disposed on the downstream side of the steam inlet 11 c in the blowing direction when the blower fan 20 is rotated, and the steam inlet 11 c side of the temperature sensor 50 is disposed on the left side wall of the cooking chamber 11. A shielding plate 51 is attached to the front. The shielding plate 51 is made of an L-shaped plate member protruding from the left side wall to the cooking chamber 11 side, and the steam introduced from the steam inlet 11c is blown by the blower fan 20 and directly blown to the temperature sensor 50. In addition, the water droplets introduced together with the steam from the steam inlet 11c are not blown by the blower fan 20 and hit the temperature sensor 50. Further, since the shielding plate 51 blocks the position on the heater 30 side of the temperature sensor 50, the temperature sensor 50 is difficult to detect the radiant heat of the heater 30.

  The control device 60 includes a microcomputer and is connected to the fan motor 21, the heater 30, the steam generation device 40, and the temperature sensor 50 as shown in FIG. 3. The control device 60 stores a cooking program in a memory (not shown), controls the operation of the heater 30 from the temperature detected by the temperature sensor 50 based on the cooking program, and controls the operation of the fan motor 21 and the steam generator 40. is doing.

  In the heating cooker 10 configured as described above, the temperature sensor 50 detects the temperature of hot air generated by the blower fan 20 and the heater 30, and the control device 60 is based on the temperature detected by the temperature sensor 50. When the operation of the heater 30 is controlled such that the temperature inside the heater 11 is higher than the temperature of the steam (100 ° C.), for example, 200 ° C., the steam introduced from the steam inlet 11 c is supplied to the temperature sensor 50. When directly hit, the temperature detected by the temperature sensor 50 is lower than the temperature of the hot air generated by the blower fan 20 and the heater 30 due to the influence of steam at a temperature of 100 ° C. Similarly, when a water droplet introduced together with steam from the steam inlet 11c directly hits the temperature sensor 50, the temperature detected by the temperature sensor 50 is the temperature of hot air generated by the blower fan 20 and the heater 30 due to the influence of the water droplet. The temperature is lower than the temperature. However, when the heating cooker 10 of this embodiment arrange | positions the temperature sensor 50 downstream from the steam inlet 11c in the ventilation direction when rotating the ventilation fan 20, the heating space 11b side of the cooking chamber 11 is provided. Since the shielding plate 51 is provided on a side wall of the temperature sensor 50 at a position on the steam inlet 11c side of the temperature sensor 50, the steam introduced from the steam inlet 11c rides on the air blown by the blower fan 20 and is on the temperature sensor 50 side. Even if water droplets that are sprayed on the steam or introduced from the steam inlet 11c together with the steam are sent to the temperature sensor 50 by being blown by the blower fan 20, the shield plate 51 may cause the steam or water droplets to hit the temperature sensor 50. Therefore, the temperature sensor 50 accurately detects the temperature of hot air generated by the blower fan 20 and the heater 30 without being affected by steam or water droplets. Door can be.

The temperature sensor 50 </ b> A is disposed upstream of the steam inlet 11 c in the blowing direction when the blower fan 20 is rotated. The temperature sensor 50A is disposed at a position directly below the steam inlet 11c. A shielding plate 51A is attached to the left side wall of the cooking chamber 11 on the upper side which is the steam inlet 11c side of the temperature sensor 50A. The shielding plate 51A is made of an L-shaped plate member protruding from the left side wall to the cooking chamber 11 side, and prevents a water droplet introduced together with the steam from the steam inlet 11c and dropping downward from hitting the temperature sensor 50A. Is. Further, since the shielding plate 51A blocks the position on the heater 30 side of the temperature sensor 50A, the temperature sensor 50A is difficult to detect the radiant heat of the heater 30.

  In the heating cooker 10A configured as described above, the temperature sensor 50A detects the temperature of hot air generated by the blower fan 20 and the heater 30, and the inside of the cooking chamber 11 is, for example, based on the temperature detected by the temperature sensor 50A. When the operation of the heater 30 is controlled to be higher than the steam temperature (100 ° C.) such as 200 ° C., when the steam introduced from the steam inlet 11c directly hits the temperature sensor 50A, The temperature detected by the temperature sensor 50 </ b> A is lower than the temperature of hot air generated by the blower fan 20 and the heater 30 due to the influence of steam at a temperature of 100 ° C. Similarly, when a water droplet introduced together with steam from the steam inlet 11c directly hits the temperature sensor 50A, the temperature detected by the temperature sensor 50A is the temperature of hot air generated by the blower fan 20 and the heater 30 due to the influence of the water droplet. The temperature is lower than the temperature. However, the heating cooker 10A of the present embodiment has been introduced from the steam inlet 11c because the temperature sensor 50A is disposed upstream of the steam inlet 11c in the blowing direction when the blower fan 20 is rotated. Steam or water droplets are not blown by the blower fan 20 and hit the temperature sensor 50 </ b> A, and the temperature sensor 50 </ b> A can accurately detect the temperature of the hot air generated by the blower fan 20 and the heater 30. Further, in the heating cooker 10A of the present embodiment, the temperature sensor 50A is directly below (lower side) the steam inlet 11c, and the left wall on the heating space 11b side of the cooking chamber 11 is shielded above the temperature sensor 50A. Since the plate 51A is provided, water drops introduced together with the steam from the steam inlet 11c and falling do not hit the temperature sensor 50A by the shielding plate 51A. Therefore, the temperature sensor 50A is a hot air generated by the blower fan 20 and the heater 30. Temperature can be detected accurately.

  In this heating cooker 10C, the temperature sensor 50C includes a first temperature sensor 50C1 attached to a position on the outer peripheral side of the heater 30 on the front wall side upper part of the one side wall of the cooking chamber 11, and a fan. The cover 22 includes a second temperature sensor 50 </ b> C <b> 2 attached at a position near the suction port of the blower fan 20. The first temperature sensor 50 </ b> C <b> 1 is disposed downstream of the steam inlet 11 c in the blowing direction when the blower fan 20 is rotated, and the first temperature sensor 50 </ b> C <b> 1 is disposed on the left side wall of the cooking chamber 11. A shielding plate 51C is attached to the steam inlet 11c side. The shielding plate 51C is made of an L-shaped plate member protruding from the left side wall to the cooking chamber 11 side, and the steam introduced from the steam inlet 11c rides on the air blown by the blower fan 20 to the first temperature sensor 50C1. The water droplets introduced together with the steam from the steam inlet port 11c are prevented from being directly sprayed and are prevented from hitting the first temperature sensor 50C1 by being blown by the blower fan 20. Further, since the shielding plate 51C blocks the position on the heater 30 side of the first temperature sensor 50C1, it is difficult for the first temperature sensor 50C1 to detect the radiant heat of the heater 30.

  The control device 60 calculates the average temperature of both detected temperatures of the first temperature sensor 50C1 and the second temperature sensor 50C2 as a temperature calculated from both detected temperatures of the first temperature sensor 50C1 and the second temperature sensor 50C2. Based on the above, the operation of the heater 30 is controlled. The temperature detected by the first temperature sensor C1 is the temperature of the air immediately after the air sucked from the cooking space 11a by the blower fan 20 is heated by passing through the heater 30, and thus is stored in the cooking space 11a. It is slightly higher than the food temperature. The temperature detected by the second temperature sensor C2 is the temperature of the air sucked into the blower fan 20 again after heat exchange is performed by heating the food containing hot air sent from the heating space 11b to the cooking space 11a. Since it is temperature, it is slightly lower than the temperature of the foodstuff accommodated in the cooking space 11a. Therefore, the control device 60 controls the operation of the heater 30 based on the average temperature of both the detected temperatures of the first temperature sensor 50C1 and the second temperature sensor 50C2, so that the temperature is close to the food stored in the cooking space 11a. Based on this, the operation of the heater 30 can be controlled.

  Moreover, the control apparatus 60 is provided with the calculation means which calculates the weight of the foodstuff in the cooking chamber 11 from the temperature difference of the detected temperature of the 1st temperature sensor 50C1 and the detected temperature of the 2nd temperature sensor 50C2. The calculation means will be described in detail. The memory of the control device 60 stores the weight of the food stored in the cooking chamber 11 for each cooking menu of the food, the first temperature sensor C1 corresponding to the weight of the food, and the first temperature sensor C1. The data including the temperature difference with the second temperature sensor C2 is recorded, and the calculation means of the control device 60 calculates the detected temperature of the first temperature sensor 50C1 and the detected temperature of the second temperature sensor 50C2 based on the data. The weight of the foodstuff in the cooking chamber 11 is calculated from the temperature difference.

  In the heating cooker 10C configured as described above, the temperature of hot air generated by the blower fan 20 and the heater 30 detected by the first temperature sensor 50C1 according to the amount of food stored in the cooking space 11a of the cooking chamber 11 In some cases, the temperature of the air sucked from the cooking space 11a detected by the second temperature sensor 50C2 is greatly different. At such time, the control device 60 controls the operation of the heater 30 based on the average temperature of both the detected temperatures of the first and second temperature sensors 50C1 and C2. The operation is controlled based on a temperature close to the temperature of the contained foodstuff. Thereby, 10 C of heating cookers can perform now accurate temperature control close | similar to the temperature of the accommodated foodstuff irrespective of the quantity of the foodstuff accommodated in the cooking chamber 11. FIG.

  In the heating cooker 10C thus configured, the control device 60 calculates the weight of the ingredients in the cooking chamber 11 from the temperature difference between the temperature detected by the first temperature sensor 50C1 and the temperature detected by the second temperature sensor 50C2. Since the calculation means is provided, the weight of the food can be calculated without providing a weight sensor or the like for detecting the weight of the food in the cooking chamber 11, and the operation of the heater 20 is controlled according to the weight of the food. It becomes possible to carry out the heating cooking.

  In the fourth embodiment, the first temperature sensor 50 </ b> C <b> 1 is arranged downstream of the steam inlet 11 c in the blowing direction when the blower fan 20 is rotated, and is disposed on the left side wall of the cooking chamber 11. Although the shielding plate 51C is attached to the steam inlet 11c side of the first temperature sensor 50C1, the present invention is not limited to this, and the first temperature sensor 50C1 is rotated by rotating the blower fan 20. May be arranged upstream of the steam inlet 11c in the blowing direction. When the temperature sensor 50C1 is disposed at a position directly below the steam inlet 11c, the shielding plate 51C is attached to the upper side of the temperature sensor 50C1 on the steam inlet 11c side of the left side wall of the cooking chamber 11. In this way, the effects as described in the second embodiment can be obtained.
