Description

  The present invention relates to an improvement in safety of an electric heating cooker, particularly an electric heating cooker.

  Conventionally, a heating object placed on the top plate is heated by a heating body such as an induction coil or an electric resistor. The left heating unit is on the left side of the top plate, the right heating unit is on the right side, and the center is on the rear center. An electric heating cooker having three heating parts of a heating part is known. In such a conventional electric heating cooker, the temperature of the cooking device such as a cooking pan as a heated object is detected by a temperature sensor provided on the lower surface of the top plate, thereby detecting the degree of cooking and performing heating control. , Automatic cooking and so on.

  As a temperature sensor of such an electric heating cooker, an application of a radiation temperature method using an infrared sensor with very good response has been proposed.

  Inside the main body case 2 is provided a control body 34 provided with an output control circuit for the heating body 20 including a power supply unit, various electronic elements, a microcomputer, a reservation timer control circuit, and the like. The control body 34 is connected to the heating body 20, the temperature sensor 23, and the like, and the control body 34 controls the heating output including stopping the heating of the heating body 20 or reducing the output of the heating body 20. It is configured. In addition, the electric heating cooker 1 in this embodiment is the same in which an induction coil and a temperature sensor similar to the induction coil 22 are provided on the lower surface side of the top plate 5 as shown in FIG. 3 corresponding to the circle line 7C. It has a structure. Further, in the portion corresponding to the circle line 7A, a heating body made of an electric resistor is provided on the lower surface side of the top plate 5 instead of the induction coil 22 shown in FIG. Others have the same structure as in FIG. 3, and a temperature sensor or the like is provided.

  Moreover, since the heating body 20 and the control body 34 have heat by operation | movement of the electric heating cooking appliance 1, while being provided with a radiation fin (not shown), in order to cool the heated main body case 2 inside with the motor M A blower 35 to be driven is provided in the main body case 2. When the motor M is driven and the blower 35 is operated, the outside air introduced into the main body case 2 from the intake port 18 (the white arrow in FIG. 3) is heated by the heating body 20 or the control body 34, and the like. After the top plate 5 and other heated parts are air-cooled (arrows in FIG. 3), they are discharged from the exhaust port 19 provided at the rear of the main body to the outside of the main body.

  On the other hand, the electric heating cooker 1 in the present embodiment includes a temperature measuring body 27 that measures the temperature of the object to be heated 36 on the frame 6 that is the top surface of the main body case 2. The temperature measuring body 27 is composed of an infrared sensor, and the temperature measuring body 27 is provided in two projecting portions 26 that project the front upper surface portion of the frame 6. The temperature measuring element 27 has a temperature detection unit 38, and the temperature detection unit 38 can measure the temperature without touching the object to be heated 36 by detecting infrared rays generated from the object to be heated 36. It is configured as follows. That is, the temperature measuring body 27 is provided in a protruding portion 26 in which the top panel operating portion 16 located on the front side of the frame body 6 is protruded by a predetermined dimension, and the object to be heated 36 is placed on the protruding portion 26. They are respectively provided on the top panel operation unit 16 closest to the circle line 7B on the left side of the front part and the circle line 7C on the right side of the front part.

  Both protrusions 26 form an inclined surface 28 that protrudes by a predetermined dimension from the top panel operation unit 16 as the distance from the circle lines 7B and 7C increases, and further from the top panel operation unit 16 as the distance from the upper end of the inclined surface 28 increases. It is formed so as to project into a mountain shape with an opposite inclined surface 30 that gently inclines to a planar position. The inclined surface 28 is directed downward from the center of the overall height of the object to be heated 36 placed on the circle lines 7B and 7C, and is directed upward by a predetermined dimension from the lower end of the object to be heated 36. Specifically, assuming that the height of the object to be heated 36 is divided into 10 parts, the inclined surface 28 is oriented between 2 to 5 parts from the lower part to the upper part at the height of the object to be heated 36 such as a general pan. Yes.

  As shown in FIG. 4, the inclined surface 28 is provided with a through hole 28 </ b> A, and a holding portion 29 is provided around the through hole 28 </ b> A so as to extend inside the protruding portion 26 and hold the temperature measuring body 27. It has been. The temperature measuring body 27 is inserted into the holding portion 29 from the inside of the protruding portion 26, and is inserted to the inclined surface 28 to be substantially flush. When the temperature measuring body 27 is exposed in the direction of the object to be heated 36 from the through hole 28A and the height of the object to be heated 36 that is the same as the inclined surface 28 is divided into ten parts, the object to be heated 36 such as a general pan is heated. It is bonded and fixed with an adhesive (not shown) from the inside of the protrusion 26 in a state where it is oriented between 2 to 5 divisions from the lower part to the upper part at the height. That is, by exposing the temperature detector 38 of the temperature measuring body 27 from the through hole 28 </ b> A of the inclined surface 28, infrared rays generated from the heated object 36 can be directly detected. That is, the protrusion 26 has an inclined surface 28 on the side of the top plate 5 on the side opposite to the user on which the object to be heated 36 is placed, and the temperature measuring body 27 is disposed on the inclined surface 28 so that the temperature of the object to be heated 36 is increased. It is arranged so that can be measured.

  In the electric heating cooker 1 in the present embodiment, the temperature measuring body 27 is formed on the frame 6 on the outer periphery of the top plate 5 in the vicinity of the object to be heated 36, and from the center in the front-rear direction of the top surface of the electric heating cooker 1. Since it is provided on the front side, for example, when the temperature measuring body 27 is provided at the rear part of the frame body 6 on the outer periphery of the top plate 5, other cooking pots or dishes are placed between the temperature detection unit 38 and the heated object 36. There may be inconveniences such as the temperature of the object to be heated 36 being impossible to measure, but this can be avoided. Thereby, the certainty of the temperature measurement of the to-be-heated material 36 can be improved. In particular, unlike the case where the temperature measuring body 27 is provided at the rear part of the frame 6 on the outer periphery of the top plate 5, the temperature detection unit 38 of the temperature measuring body 27 does not face the user side. Inconveniences such as measuring the temperature of the user when 36 is not placed can also be prevented.

  On the other hand, as shown in FIG. 3, notification means 32 is provided on the inclined surface 30 formed on the opposite side of the inclined surface 28 of the protruding portion 26. The notification means 32 is provided corresponding to the front part of each of the circle lines 7B and 7C, and when there is an abnormality in the electric heating cooker 1, for example, a display means for notifying with letters or pictures, a notification sound It is comprised with the sound generation means to generate | occur | produce. The display means is composed of a plurality of 7-segment LEDs and liquid crystal displays that can display characters, pictures, etc., and the sound generating means is a buzzer or speaker that generates sound, a constant sound or a whistle sound, etc. It is configured. The temperature of the object to be heated 36 detected by the temperature measuring element 27 (temperature detection unit 38) is displayed on a plurality of 7-segment LEDs, a liquid crystal display, or the like as the notification means 32.

  The notification means 32 is connected to the control body 34, and when the abnormal temperature rise of the object to be heated 36 or the temperature detection unit 38 of the temperature measuring body 27 cannot be detected sufficiently, the notification means 32 notifies the content of the abnormality with characters or pictures. At the same time, it announces by voice and sound. For example, when an abnormal temperature rise is announced, “abnormally high temperature” is reported, or when the temperature rise cannot be detected sufficiently, “The correct temperature cannot be detected. Is the heated object placed in the correct position? Make sure that the surface of the detector is clean and that there are no obstructions between the heated object and the detector. " Thereby, the user can grasp | ascertain rapidly the abnormal content of the electric heating cooking appliance 1. FIG. In addition, since the protrusion 26 is provided at the front of the frame 6 corresponding to each object to be heated 36, it is possible to grasp at a glance which object to be heated 36 is abnormal and display means. Since the abnormality can be grasped by the sound notification from the sound generating means without visually recognizing, the abnormality of the electric heating cooker 1 can be grasped more quickly.

  In other words, since the temperature measuring element 27 is provided so as to protrude from the top surface of the top plate 5, compared with the conventional case where the heated object 36 on the top surface is measured from the bottom side of the top plate through the top plate. It becomes possible to directly measure the outer surface of the heated object 36. Thereby, the temperature of the article to be heated 36 can be measured more accurately. In addition, since abnormalities such as dirt on the outer surface of the temperature detection unit 38 of the temperature measuring body 27 are notified by display or sound, the outer surface of the temperature detection unit 38 of the temperature measurement body 27 is covered with moisture due to boiling. Inconvenience can be prevented, and the temperature of the object to be heated 36 can be measured more accurately.

  As described above, the temperature measuring body 27 is provided in the projecting portion 26 corresponding to the object to be heated 36, and the notification means 32 is provided in the vicinity of the temperature measurement body 27. It is convenient that the temperature of the object to be heated 36 is measured and displayed on the display 27 and the temperature of the object to be heated 36 is not mistaken. Moreover, since the notification means 32 is provided in the vicinity of the temperature measuring body 27, the cleaning location is easy to understand and convenient. Thereby, when the surface of the temperature detection part 38 of the temperature measuring body 27 is soiled with boiled juice, water droplets, dust, etc., and the notification means 32 notifies the abnormality, the temperature detection part of the temperature measurement body 27 in the vicinity of the notification means 32 Abnormalities can be easily avoided simply by cleaning 38. In this embodiment, the display means and the sound generation means are provided as the notification means 32. However, the notification means 32 may be either the display means or the sound generation means. In this case, since either one can be notified of an abnormality, the number of parts can be reduced and the cost can be reduced.

  In addition, with the temperature measuring body 27 fixed to the inclined surface 28 of the protruding portion 26, the temperature measuring body 27 is directed downward from the center of the height of an object to be heated 36 such as a general pan, and Since the temperature measuring body 27 is directed upward from the lower part of the heated object 36 by a predetermined dimension, the temperature measuring element 27 can directly detect the temperature above the lower part of the object to be heated 36 (a dotted line arrow in FIG. 3). That is, since the temperature measuring body 27 can measure the temperature below the center of the height of the object to be heated 36 and above the lower part of the object to be heated 36 by a predetermined dimension, Even when a small obstacle such as a chopstick or a spoon is placed between the objects to be heated 36, the temperature measuring element 27 can measure the temperature of the object to be heated 36 from above the obstacles. Thereby, it is prevented that the temperature detection part 38 of the temperature measuring body 27 and the to-be-heated object 36 are interrupted | blocked, and the temperature of the to-be-heated object 36 can be measured favorably. In addition, in order to respond to a wider cooking utensil such as a frying pan having a low height or a pan having a different height as the object to be heated 36, the height of the temperature measuring body 27 is set as the height of the object to be heated 36. , The inclined surface 28 is directed to a height of 2 to 5 divisions from the lower part to the upper direction in the height of an object to be heated 36 such as a general pan, particularly to a height of 2 to 3 divisions. It is good to have. Since the cooked food exists at the bottom of the cooker, it is more accurate to detect the temperature near the bottom of the cooker, and it is more susceptible to obstacles if it is lower than this. This is because it becomes difficult to cope with a relatively low cooker such as a frying pan.

  In particular, since the temperature measuring element 27 is an infrared sensor, a configuration for detecting the temperature by directly contacting the object to be heated 36 is not required, and infrared light generated from the object to be heated 36 is detected and the object to be heated 36 is detected. The temperature can be measured without touching. Thereby, since the number of parts can be reduced, the product cost can be suppressed. Further, the assembly work can be simplified by reducing the number of parts, and the cleaning work can be easily performed.

  In the prior art, the temperature of the object to be heated is detected by the infrared sensor through the top plate. However, the top plate is made of glass or ceramic that is not affected by the high frequency magnetic field. In general, glass and ceramics easily absorb infrared rays and thus are difficult to transmit. As the thickness increases, temperature detection using infrared rays lacks accuracy. In addition, some glass materials are difficult to absorb infrared rays. However, due to the nature of the top plate, they must have sufficient strength, and the use of special materials can increase costs. However, in the present embodiment, since the infrared rays emitted from the object to be heated 36 can be detected by the temperature measuring body 27 without using the top plate, the measurement can be performed very accurately while suppressing the cost.

  The protrusion 26 is formed of a metal plate different from the frame 6. Then, the protruding portion 26 is bonded and fixed to a predetermined position of the top panel operating portion 16 from the inside of the protruding portion 26 with an adhesive 26A. That is, the temperature measuring body 27 is provided on the top panel operation unit 16 that is on the front side of the center in the front-rear direction of the top surface of the electric heating cooker 1 and is formed so as to protrude from the frame body 6 adjacent to the object to be heated 36. Yes. The protruding portion 26 may be formed integrally with the frame body 6 by protruding the frame body 6. In this case, since it is not necessary to bond and fix the protruding portion 26, it is possible to reduce the number of steps for attaching the protruding portion 26.

  Further, a temperature measuring body protection wall 31 is provided on the inclined surface 28 of the protruding portion 26 to prevent the temperature measuring body 27 including the temperature detecting section 38 from being damaged by an external force. As shown in FIG. 5, the temperature measuring body protection wall 31 extends at a predetermined width from the lower end to the upper end of the inclined surface 28 and is provided on both sides of the temperature measuring body 27. The temperature measuring body protection wall 31 has the inclined surface 28 protruded by a predetermined dimension, and the inclined surface 28 and the temperature measuring body protection wall 31 are integrally formed.

  That is, a temperature measuring body protection wall 31 protruding from the inclined surface 28 by a predetermined dimension is provided on both sides of the temperature measuring body 27 provided exposed on the inclined surface 28 as shown in FIGS. In this case, it is possible to disperse the impact applied to the case where the protruding portion 26 is not provided with the inclined surface 28 and the protruding portion 26 is protruded from the top panel operating portion 16 at a substantially right angle. As a result, even when an object to be heated 36 or a cooking utensil such as a cooking pot or a plate hits the inclined surface 28, the cooking appliance hits the inclined temperature measuring body protection wall 31 and hits the inclined surface 28 at an angle. Therefore, it is possible to disperse and avoid the impact. Accordingly, the temperature detector 27 of the temperature detector 27 is not directly subjected to the impact of the object to be heated 36 or a cooking utensil such as a cooking pot or a dish, so that the temperature detector 27 is prevented from being damaged. Can be protected. Further, since the temperature measuring body 27 is provided so as to be exposed on the inclined surface 28, even if the cooked material splashes and jumps to the detection surface of the temperature measuring body 27, it is difficult for the dirt to flow down due to the inclination.

  Next, the operation of the electric heating cooker 1 will be described with reference to the flowchart of FIG. An operation using only the temperature measuring element 27 (in this case, the temperature sensor 23 for measuring the bottom surface temperature of the object to be heated 36 is not used) will be described. After the object to be heated 36 is placed in accordance with the circle line 7B as described above, the power switch provided in the operation unit 12 is turned on, the cooking time is set by the timer, and the cooking temperature is set. In step S1, the heating body 20 starts heating and proceeds to step S2.

  At the same time that the heating body 20 starts heating the cooking pan (the object to be heated 36) placed on the top plate 5, the control body 34 substitutes 0 for a variable N in step S3, and in step S4, the object to be heated 36 is heated. The temperature measuring body 27 starts the temperature measurement without contact from the side, and the temperature of the heated object 36 detected by the temperature measuring body 27 is displayed on a plurality of 7-segment LEDs, liquid crystal displays, and the like. In step S5, the control body 34 measures the object to be heated 36 after the elapse of a predetermined time in which the temperature measuring body 27 is set in advance. That is, the control body 34 measures the temperature of the heated object 36 immediately after the heating body 20 starts heating and the temperature of the heated object 36 after a predetermined time has elapsed (for example, 20 SEC to 40 SEC). After that, the process proceeds to step S6.

  In step S6, the control body 34 sets a predetermined temperature at which the temperature of the object to be heated 36 when the heating body 20 starts heating and the temperature of the object to be heated 36 after a predetermined time elapses are set in advance. When a temperature increase of 3 ° C. or more is observed from the increased value, for example, the temperature at the start of heating, the process proceeds to step S7. In step S7, the control body 34 determines whether or not the object to be heated 36 has reached the target predetermined temperature. If not, the process returns to step S4, and finally the object used for comparison. The temperature of the heated object 36 is compared with the current temperature. Finally, the temperature of the heated object 36 used for the comparison and the current temperature of the heated object 36 after the lapse of a predetermined time when the temperature is measured are obtained. When a temperature increase equal to or higher than a predetermined temperature increase value set in advance is observed, the process proceeds to step S7 again. When the target object 36 reaches the target predetermined temperature in step S7, the heating of the heating body 20 is stopped or the output of the heating body 20 is reduced in step S8.

  In step S6, the control body 34 is set in advance after measuring the temperature of the object to be heated 36 used for the last comparison by the heating body 20 and the temperature of the object 36 to be heated used for the last comparison. When the temperature of the object to be heated 36 after a predetermined time has not risen above a predetermined temperature set in advance, the process proceeds to step S9, and when the variable N reaches N + 1, that is, when S9 is reached for the first time, N Since = 0, 1 is substituted for N and the process proceeds to S10. When the variable N is not 2 or more in step S10, the process returns to step S4. That is, the control body 34 is not heated for some reason because the heated object 36 has not yet been heated, or the temperature of the heated object 36 could not be measured due to a malfunction of the temperature measuring body 27. Determination is then returned to step S4, temperature measurement of the object to be heated 36 is started again by the temperature measuring element 27, and the temperature of the object to be heated 36 is measured after a predetermined time set in advance by the temperature measuring element 27 in step S5. After that, the process proceeds to step S6 to determine whether or not a temperature increase is observed.

  Further, in step S6, the control body 34 is set in advance after measuring the temperature of the object to be heated 36 used for the last comparison by the heating element 20 and the temperature of the object 36 to be heated used for the last comparison. When the temperature of the object to be heated 36 after the predetermined time has not risen above the predetermined temperature set in advance, the process proceeds to step S9, and the value of N is updated by one and the process proceeds to step S10. Therefore, when the variable N is 2, the process proceeds to step S11 to operate the notification means 32.

Thereby, the safety | security of the electric heating cooking appliance 1 can also be improved further. In the case of such a configuration, when it is detected that the temperature rise detected by the temperature measuring body 27 exceeds the predetermined temperature rise range, the steps S33 and S34 are skipped and the process jumps to the step S29. It is good to have a simple configuration.

  Moreover, although the example which does not determine a temperature rise value etc. about the temperature measured with the temperature sensor 23 in this embodiment was shown, it corresponds to step S26 and step S29-S32 between step S33 and step S34. If such a step is provided and the temperature rise value is determined for the temperature measured by the temperature sensor 23 in the same manner as the temperature measuring body 27, the safety of the electric heating cooker 1 can be further improved.
