Background of the Invention

Field of invention

This invention relates to the improvement of the temperature detection mechanism of an electric heating cooker, especially an electric heating cooker.

Conventional technology

Conventionally, heating and cooking of a heated object placed on an upper surface of a top plate by a heating element such as an induction heating coil or an electrical resistor is performed. Three heating parts are heated on the left side of the top plate, a right side heating portion on the right side, and a central heating portion on the rear center. Electric heating cookers having a portion are known. The electric heating cooker detects the temperature of cooked food, such as food, and the temperature of the cooker, such as a cooking pot, by a temperature sensor provided on the lower surface of the top plate. When the temperature of a food or a cooker suddenly rises, safety measures, such as turning off a heating operation, are prevented in order to prevent danger beforehand.

As a temperature sensor of such an electric heating cooker, the application of the radiation temperature system by the infrared sensor which is very responsive is proposed. The electric heating cooker places a heated object on the top surface of the top plate covering the top surface opening of the box-shaped body case, provides a light emitting element such as an LED or a laser, a light receiving element, and an infrared sensor under the top plate, The light to be heated is transmitted by receiving the reflected light reflected from the object to be heated by the light-receiving element, and converting the emissivity of the object to be converted from the received output and the temperature of the object to be heated from the light receiving amount of the infrared sensor. It is configured to detect the correct temperature (see Japanese Patent Laid-Open No. 11-225881).

However, when the to-be-heated material mounted on the upper surface of the top plate is heated from the lower side of the top plate, the top plate is also heated. For example, in an electric heating cooker that heats the heated object itself and heats the heated object, the heating body first generates heat by heating the top plate in the order of temperature conduction, and the temperature of the top plate is conducted to the heated object. In order. In this method, since the heated object placed on the top plate is heated from the bottom of the top plate, the top plate tends to have a higher temperature than the heated plate, and the top plate is exposed to the upper surface of the electric cooker. It is also conceivable that the temperature is changed by receiving the.

Moreover, in the electric heating cooker which heats a to-be-heated object by induction heating, a high frequency magnetic field is generated by a heating body, an eddy current is generated in a cooking container, such as a pot which is a to-be-heated object, and a to-be-heated object is heated. In this system, since the top plate is not affected by the high frequency magnetic field and the heated object is heated, the heated object tends to have a higher temperature than the top plate. Thus, the electric heating cooker which measures the temperature of the to-be-heated object mounted on the top surface from below the top plate is a system which detects temperature by making a temperature sensor etc. contact a top plate, and the temperature sensor which contacted the top plate detects the temperature of a top plate. Throw it away. However, the temperature of the top plate and the object to be heated cannot necessarily coincide with each other as described above, and the accuracy of the detection temperature is lowered due to the temperature difference between the top plate and the object to be heated.

In addition, as described in Japanese Patent Laid-Open No. 11-225881, in the manner in which the temperature of the heated object is detected by the infrared sensor, the top plate is made of glass or the like which is not affected by the high frequency magnetic field, but the glass generally absorbs infrared rays. Since it is easy to transmit, it is difficult to transmit, and as the thickness of the glass becomes thicker, detecting temperature by infrared rays through the glass also lacks accuracy. In addition, some glass materials are difficult to absorb infrared rays, but there are also problems such as having a sufficient strength, cost, and the like due to the nature of the top plate. Thus, the electric heating cooker which measures the temperature of the to-be-heated object placed on the top plate top surface from below the top plate is interposed between the to-be-heated material and an infrared sensor, so it is an infrared sensor provided under the top plate to the top plate top surface. When the temperature of the heated object placed is detected, there is a problem that the temperature of the heated object cannot be detected by the influence of the top plate.

This invention is made | formed in view of the said subject, and an object of this invention is to provide the electric heating cooker which can improve the measurement precision of the temperature of a to-be-heated object.

In order to achieve the above object, the electric heating cooker according to the present invention includes a top plate on which the heated object is placed, a frame provided on an outer circumference of the top plate, a body case in which the top plate and the frame are arranged on a top surface, A heating body for heating the heated object by an induction heating coil, an electric resistor, or the like, a control body for controlling the output of the heating body, a blower for cooling the heat generating parts provided in the main body case, and the heated object A temperature measuring body having a temperature detecting unit for measuring temperature is provided, and a protrusion is provided to protrude the front upper surface of the frame, and the temperature measuring body is disposed in the protrusion.

According to the electric heating cooker of this invention, since the heat which a to-be-heated thing generate | occur | produces can be detected by a temperature measuring body through a top plate, the temperature of a to-be-heated object can be measured correctly.

On the lower surface side of the circle lines 7A, 7B, and 7C, as shown in FIG. 3, the induction wound on the coil stage 22A in a spiral shape on the lower surface side of the top plate 5 to be inside the main body case 2. The heating body 20 which heats with the heating coil 22, an electrical resistor (not shown), etc. is provided.

Further, a temperature sensor 23 is provided at the center of the induction heating coil 22 to measure the bottom surface temperature of the heated object 36 placed on each circle line in contact with the bottom surface of the top plate 5. In addition, in FIG. 3, it demonstrates using the longitudinal side view of the circle line 7B of the electric heating cooker 1. As shown in FIG.

Inside the main body case 2, the control body 34 provided with the output control circuit of the heating body 20 containing a power supply part, various electronic elements, a microcomputer, etc., a reservation timer control circuit, etc. are provided. The heating body 20, the temperature sensor 23, etc. are connected to the control body 34, and the control body 34 stops heating of the heating body 20, or the output of the heating body 20 falls. It is configured to be able to. In addition, an induction heating coil and a temperature sensor such as the induction heating coil 22 are connected to the lower surface side of the top plate 5 corresponding to the circle line 7C, and the lower surface side of the top plate 5 is connected to the circle line 7A. Although a heating body made of a resistor, a temperature sensor, and the like are provided, they are not shown.

In addition, since the heating body 20 and the control body 34 have heat by the operation of the electric heating cooker 1, heat radiating fins (not shown) are provided and the inside of the heated body case 2 is cooled. In order to achieve this, a blower 35 driven by a motor M is provided in the main body case 2. Then, when the motor M is driven and the blower 35 is driven, the outside air introduced into the main body case 2 from the intake port 18 (the hollow arrow in FIG. 3) is the heater 20 or the control body ( After cooling the heating components such as 34) and the top plate 5 and other heated components (arrows in FIG. 3), they are discharged to the outside of the main body from the exhaust port 19 provided at the rear of the main body.

On the other hand, the electric heating cooker 1 in this embodiment is equipped with the temperature measuring body 27 which measures the temperature of the to-be-heated thing 36 in the edge 6 used as the top surface of the main body case 2. As shown in FIG. . This temperature measuring body 27 is comprised by the infrared sensor, and is provided in the two projection part 26 which protruded the front upper surface part of the edge 6, respectively. The temperature measuring body 27 has a temperature detecting unit 38, and the temperature detecting unit 38 measures the temperature without contacting the heated object 36 by detecting infrared rays generated from the heated object 36. It is configured to do so. That is, the temperature measuring body 27 is provided in the projection part 26 which protrudes the top plate operation part 16 located in the front side of the frame 6 by predetermined dimension, and as shown in FIG. 1 and FIG. 26 is provided in the top plate | board operation part 16 which is the nearest to the circle line 7B of the all left side in which the to-be-heated object 36 is placed, and the circle line 7C of the all right side, respectively.

As shown in FIG. 3, both of the protrusions 26 include an inclined surface 28 that protrudes from the top plate operating portion 16 by a predetermined dimension as separated from the circle lines 7B and 7C. As it is further separated from the upper end, it protrudes in the form of a mountain with the top plate operating part 16 and the opposite inclined surface 30 which inclines gently to a planar position. The inclined surface 28 is directed downward below the center of the entire height of the heated object 36 placed on the circle lines 7B and 7C, and is lower than the lower end of the heated object 36. The predetermined dimension is directed upward. Specifically, assuming that the height of the heated object 36 is divided into 10, the inclined surface 28 is directed between two to five divided portions from the lower portion of the heated object 36 to the upper direction.

As shown in Fig. 4, the inclined surface 28 is provided with a through hole 28A, and around the through hole 28A, a support portion for extending the inside of the protrusion 26 and supporting the temperature measuring body 27 ( 29) is provided. The temperature measuring body 27 is inserted into the support part 29 from the inner side of the projection part 26, and is inserted in the inclined surface 28 until it becomes substantially the same plane. The temperature measuring body 27 is exposed from the through-hole 28A in the direction of the object to be heated 36, and the height of the object to be heated 36 which is the same as the inclined surface 28 is divided into ten. Adhesively fixed to the adhesive agent (not shown) from the inner side of the projection part 26 in the state which directed between 2-5 divisions from the lower part of 36 to the upper direction. That is, by exposing the temperature detection part 38 of the temperature measuring body 27 from the through hole 28A of the inclined surface 28, the infrared rays which generate | occur | produce from the to-be-heated object 36 can be detected directly. And the projection part 26 has the inclined surface 28 in the to-be-heated object 36 mounting side of the top plate 5 which is opposite to a user, and the temperature measuring body 27 is a thing to be heated from the inclined surface 28 ( It is arranged to measure the temperature of 36).

In this embodiment, the temperature measuring body 27 is formed in the frame 6 on the outer periphery of the top plate 5 in a manner close to the heated object 36 as described above, and the front and rear directions of the top surface of the electric heating cooker 1 are performed. Since the temperature measurement body 27 is provided in the rear of the frame 6 of the outer periphery of the top plate 5, for example, the front side is provided on the front side of the center of the top plate 5, between the temperature detection unit 38 and the heated object 36. An unreasonable effect, such as an empty cooking pot, a dish, or the like, being placed and the temperature of the heated object 36 becomes unmeasurable can be avoided. Thereby, the temperature of the to-be-heated object 36 can be measured reliably. In particular, since the temperature detecting unit 38 of the temperature measuring body 27 does not face the user side, the temperature of the user is measured when the object to be heated 36 is not placed on the top plate 5. Irrationality can also be prevented.

On the other hand, on the opposite inclined surface 30 formed on the opposite side to the inclined surface 28 of the projection part 26, as shown in FIG. 3, the notification means 32 is provided. The notification means 32 is provided corresponding to all of the circle lines 7B and 7C, respectively, and displays means for notifying the abnormality of the electric heating cooker 1 by letters, pictures, or the like, and generating a notice sound. It is composed of sound generating means. The display means is composed of a plurality of seven-segment LEDs, liquid crystal displays, and the like capable of displaying letters, pictures, and the like, and the sound generating means is composed of a buzzer, a speaker, and the like for generating voice, constant sound, whistle, and the like. The temperature of the to-be-heated object 36 detected by the temperature measuring body 27 (temperature detecting part 38) is displayed on LED of 7 segments as a notification means 32, a liquid crystal display, etc.

The notification means 32 is connected to the control body 34, and when an abnormal temperature rise of the heated object 36 or an abnormality such as surface contamination of the temperature detection part 38 of the temperature measuring body 27 occurs, Notify the contents of the above by text or picture, and voice or sound. Thereby, a user can grasp | ascertain the abnormal content of the electric heating cooker 1 quickly. Moreover, since the projection part 26 is provided in all the edges 6 corresponding to each to-be-heated object 36, while being able to grasp | ascertain what kind of to-be-heated object 36 an abnormality arises at the same time, Since abnormality can be grasped | ascertained by the sound notification from a sound generating means, without visually identifying a display means, abnormality of the electric heating cooker 1 can be grasped | ascertained more quickly.

These notification means 32 are the measurement results of the temperature measuring body 27, such as the case where the temperature detected by the temperature measuring body 27 is absent or abnormally small even though the heating body 20 is operating in the present embodiment. Is configured to display or sound the failure of the temperature measuring body and the contamination of the outer surface of the temperature measuring body, and the heating body 20 and the temperature measuring body 27 are provided by such a notification means 32. It is a helper that the user accurately grasps abnormalities related to heating, such as failure or cleaning of contamination on the outer surface of the temperature measuring body 27, and can provide a great sense of security to the user. In addition, since the influence of the external surface contamination of the temperature measuring body can be quickly eliminated, the temperature of the measurement object can be accurately measured without being affected by the external surface contamination of the temperature measuring body or the like.

In addition, since the temperature measuring body 27 is provided to protrude from the upper surface of the top plate 5, compared with the case where the heating target object 36 on the upper surface is measured from the lower side of the top plate through the top plate as in the prior art, It is possible to directly measure the outer surface of the water 36. Thereby, the temperature of the to-be-heated object 36 can be measured more correctly. In addition, since the contamination of the outer surface of the temperature detecting unit 38 of the temperature measuring body 27 is reported to be negative or negative, for example, the outer surface of the temperature detecting unit 38 of the temperature measuring body 27 boils during cooking. Discomfort such as being covered with moisture due to overflow can be prevented, and the temperature of the heated object 36 can be measured more accurately.

Thus, since the temperature measuring body 27 is provided in the projection part 26 corresponding to the to-be-heated object 36, and the notification means 32 is provided in the vicinity of the temperature measuring body 27, a notification means ( Only by referring to 32, it is possible to know which heated object 36 the temperature measuring body 27 measures and displays, and it is convenient because it must be the temperature of which heated object 36. Moreover, since the notification means 32 is provided in the vicinity of the temperature measuring body 27, the cleaning place is easy to understand and convenient. As a result, when the surface of the temperature detector 38 of the temperature measuring body 27 becomes dirty with boiled water, water droplets, dust, or the like, and the notification means 32 reports an abnormality, the temperature measurement near the notification means 32 is measured. The abnormality can be easily avoided only by cleaning the temperature detection part 38 of the sieve 27. In addition, although the display means and the sound generating means are provided in the notification means 32, the notification means 32 may be any one of the display means and the sound generating means. In this case, since either or both can be notified of the abnormality, the number of parts can be reduced and the cost can be reduced.

Further, in a state where the temperature measuring body 27 is fixed to the inclined surface 28 of the protrusion 26, the temperature measuring body 27 is directed downward from the center of the height of the heated object 36, and Since the temperature measurement object 27 is directed above the lower part of the heating object 36, the temperature measuring body 27 can directly detect the temperature of the upper part of the heating object 36 above the predetermined dimension (dotted arrow in FIG. 3). . That is, since the temperature measuring body 27 is lower than the center of the height of the to-be-heated object 36, and it is possible to measure the temperature of a predetermined dimension above the lower part of the to-be-heated object 36, the temperature measuring body 27 Even when small obstacles such as chopsticks or spoons are placed between the temperature detection unit 38 and the object to be heated 36, the temperature measuring element 27 adjusts the temperature of the object to be heated 36 from above the obstacle. It can be measured. Thereby, blocking | blocking between the temperature detection part 38 of the temperature measuring body 27 and the to-be-heated object 36 is prevented, and the temperature of the to-be-heated object 36 can be measured favorably. Moreover, in order to respond to various cooking utensils, such as a frying pan with a low height as a to-be-heated object 36, and a pot with a different height, the height of the to-be-heated substance 36 is made into the height which the temperature measuring body 27 directs. If the 10 is divided, the inclined surface 28 is oriented between 2 to 5 divisions, particularly 2 to 3 divisions, from the lower part to the upper direction in the height of the heated object 36 such as a general pot. It is good. Since the food is present at the bottom of the cooker, it is possible to measure the temperature of a portion near the bottom of the cooker for accurate temperature detection, and if it is lower than this, it is easy to be affected by obstacles. This is because it becomes difficult to cope with a relatively low height cooker.

In particular, since the temperature measuring body 27 is an infrared sensor, it does not require a configuration of directly contacting the heated object 36 to detect the temperature, and detects the infrared rays generated from the heated object 36 to avoid it. The temperature can be measured without contacting the heating body 36. Thereby, since the number of parts can be reduced, product cost can be held down. Furthermore, by reducing the number of parts, assembly work can be simplified, cleaning work, etc. can be performed easily. In this embodiment, since the infrared rays emitted by the heated object 36 can be detected by the temperature measuring body 27 without passing through the top plate, the temperature can be measured extremely accurately while reducing the cost.

In addition, in this embodiment, the projection part 26 is comprised from the frame 6 and the metal plate separate. And the projection part 26 is adhesively fixed to the predetermined position of the top plate operation part 16 with the adhesive agent 26A from the inside of the projection part 26. As shown in FIG. That is, the temperature measuring body 27 is provided in the top plate operation part 16 which is provided in front of the center of the front-back direction of the top surface of the electric heating cooker 1, and the frame 6 which adjoins to the to-be-heated object 36 is carried out. It is formed to protrude. For this reason, even when a heated object is placed on the top plate operation part 16 located in front of the top plate 5 of the electric heating cooker 1, the heated to-be-heated object 36 touches the projection part 26. As shown in FIG. Since the projection part 26 is comprised by the metal plate, even if some heat is applied, it does not deform | transform, and it can prevent that the heated to-be-heated object 36 directly contacts the top plate operation part 16 by this. Accordingly, it is possible to reliably prevent irrationality such as deformation of the top plate operating portion 16 (the operation button 16A or the display portion 16B) mainly formed of resin or the like due to the heat of the heated object 36. . In addition, the protrusion part 26 may protrude the frame 6 formed of metal, and may be formed integrally with the frame 6. In this case, the attachment and fixation of the projections 26 becomes unnecessary, so that the labor for attaching the projections 26 can be reduced.

Moreover, since the projection part 26 has the inclined surface 28, even if it collides with the projection part 26, for example when lifting the to-be-heated object 36 from the top plate 5, the impact will be alleviated and blood will be avoided. Deformation of the heating substance 36 and overflow of the food inside are prevented. In addition, even when the temperature detection unit 38 is contaminated, the user is easy to recognize the contamination, and cleaning is easy. In particular, in general pots and pans, the bottom corners are formed in an R shape, and the height of the projections 26 is formed to be equal to or less than the height of the R shape so that the impact due to the collision can be further reduced.

Moreover, the inclined surface 28 of the protrusion part 26 in this embodiment is provided with the protrusion wall 31 for preventing the temperature measuring body 27 including the temperature detection part 38 from being damaged by external force, have. As shown in FIG. 5, the protruding wall 31 extends from the lower end to the upper end of the inclined surface 28 in a predetermined width and is provided on both sides of the temperature measuring body 27. The protruding wall 31 protrudes the inclined surface 28 by a predetermined dimension and integrally forms the inclined surface 28 and the protruding wall 31.

That is, as shown in FIGS. 5 and 6, protruding walls 31 protruding a predetermined dimension from the inclined surface 28 are provided on both sides of the temperature measuring body 27 exposed to the inclined surface 28. In this case, the impact hit against the case where the protrusion 26 is projected at a right angle to the top plate operating portion 16 without providing the inclined surface 28 on the protrusion 26 can be dispersed. Thus, even when the object to be heated 36 or cooking utensils such as a cooking pot or a plate collides with the inclined surface 28, the cooker is slanted together with the inclined protrusion wall 31 firstly on the inclined surface 28. Since it collides, it can disperse | distribute the impact which hit. Therefore, since the temperature detecting part 38 of the temperature measuring body 27 does not directly receive the impact of the heated object 36 or cooking utensils such as a cooking pot or a dish, the temperature measuring body 27 is damaged or the like. It can prevent and protect the absurdity of. Moreover, since the temperature measuring body 27 is provided by exposing to the inclined surface 28, even if a food splashes and flies to the detection surface of the temperature measuring body 27, it flows down by the inclination and contaminates, for example. This is hard to stick.

The display means is constituted by a liquid crystal display capable of displaying characters, pictures, and the like, while the sound generating means is constituted by a buzzer, a speaker or the like which generates sound such as a voice, a constant sound or a whistle. In addition, the notification means 32 is capable of displaying letters or the like for prompting cleaning when contamination occurs on the temperature measuring body 27.

On both sides of the projections 26, a plurality of seven-segment LEDs, a liquid crystal display, and the like are provided to correspond to the heated object 36 placed on the circle line. In this embodiment, it is comprised so that the temperature of the to-be-heated object 36 detected by the temperature measuring body 27, the cooking time by the timer input to the operation part 12, etc. may be displayed on this display means, respectively.

Thus, since the one projection part 26 provided with the temperature measuring body 27 is provided in the front surface side of the frame 6 outer periphery of the top plate 5, the projection part 26 is provided by the one projection part 26. The temperature of the to-be-heated object 36 provided in the both sides of () and mounted on a circle line can be detected, respectively. In this case, since the temperature measuring body 27 which measures the temperature of the some to-be-heated object 36 is accommodated in the one projection part 26 provided in the middle of both circle lines, the to-be-heated object 36 is It is mounted on the rear circle line obliquely of the temperature measuring body 27.

Thereby, when mounting or lifting the to-be-heated object 36 on a circle line from the front side of the electric heating cooker 1, the projection part 26 is convenient without being disturbed. Therefore, in the case where the projections 26 are provided on the circle lines facing each other as described above, the heated object 36 hits the projections 26 when the heated object 36 is placed or lifted. Since the hitting probability can be reduced, the possibility that the temperature measuring body 27 accommodated in the projection part 26 is damaged can be further reduced.

For example, even if the object to be heated 36 or a cooking utensil such as a cooking pot or a plate has hit the protrusion 26, as described above, the cooking utensils are obliquely bumped and inclined along the protruding wall 31. ), The impact that is hit can be avoided, and the impact that is hit can be dispersed. Therefore, since the temperature detecting unit 38 of the temperature measuring body 27 does not directly receive the impact of the heated object 36 or cooking utensils such as a cooking pot or a dish, the temperature measuring body 27 is damaged or the like. Irrationality can be better prevented and protected. Moreover, since the protrusion part 26 may be provided only in one place on the top plate 5, the number of the protrusion parts 26 is minimum and assembly workability can be improved.

In addition, in this embodiment, although the some temperature measuring body 27 was provided in one protrusion part 26, only one temperature measuring body 27 is provided in one protrusion part 26, and temperature measurement is carried out. The sieve 27 may be configured to change directions in the directions of the plurality of objects to be heated 36 at predetermined times using a motor or the like. Even in such a configuration, the plurality of heated objects 36 can be measured with one temperature measuring body 27, and only one relatively high temperature measuring body 27 can be formed, thereby reducing product cost. We can plan.

Third embodiment

The electric heating cooker 1 in this embodiment has the structure similar to the above-mentioned each embodiment. The other parts will be described below. In addition, the same code | symbol is attached | subjected to the same part as each embodiment mentioned above, and description is abbreviate | omitted. As shown in FIG. 8, the temperature measuring body 27 measures the upper temperature measuring body 27A for measuring the upper side of the heated object 36 and the lower temperature measuring for measuring the lower side of the heated object 36. A sieve 27B is provided.

The temperature measuring body 27 is configured to measure the upper side and the lower side of the heated object 36 simultaneously with the upper temperature measuring body 27A and the lower temperature measuring body 27B. When the lower temperature measuring body 27B divides the height of the heated object 36 such as a general pot by 10, the lower temperature measuring body 27B directs between 2 and 5 divided portions from the lower portion of the heated object 36 to the upper direction. The phase temperature measuring body 27A is directed between 6 to 8 divisions from the bottom of the to-be-heated object 36 to the upper direction when the height of the heated object 36 such as a general pot is divided into 10. . That is, the upper side of the object to be heated 36 is measured by the upper temperature measuring body 27A, and the lower side of the object to be heated 36 is simultaneously measured by the lower temperature measuring body 27B. Moreover, the temperature of the to-be-heated object 36 of the lower side which the heated to-be-contacted object tends to become lower than the temperature of the to-be-heated object 36 of the upper side which does not contact the to-be-processed object. That is, the temperature of the heated object 36 is measured by the lower temperature measuring body 27B which measures the temperature of the lower side regardless of the large amount or the small amount of the workpiece contained in the heated object 36. If so, the temperature of the heated object 36 can be measured accurately.

And when cooking foods, for example, frying, etc. in the to-be-heated thing 36 are being fried, when heating continues, the fried oil will evaporate, and when the oil inside becomes small, the upper direction of the to-be-heated thing 36 will be abnormal. There is a possibility of high temperature. In this embodiment, since the temperature measuring body 27 can simultaneously measure the upper side and the lower side of the object to be heated 36 by the upper temperature measuring body 27A and the lower temperature measuring body 27B. Abnormal high temperature can be detected and heating can be stopped, and the safety of the electric heating cooker 1 can be improved further.

In this way, cooking of the object to be heated 36 or a cooking pot or a dish is provided on the projection 26 provided with the temperature measuring body 27 having the upper temperature measuring body 27A and the lower temperature measuring body 27B therein. Even when the utensils are hit, as described above, their cooking utensils hit the inclined surface 28 and the protruding wall 31 at an angle, and thus the first hit the inclined protruding wall 31, thereby avoiding the impact of the hit. Moreover, the impact which hit the case where it protruded from the top plate operation part 16 at right angles, without providing the inclined surface 28 in the projection part 26 can be disperse | distributed. Therefore, since the temperature detecting part 38 of the temperature measuring body 27 does not directly receive the impact of the heated object 36 or cooking utensils such as a cooking pot or a dish, the temperature measuring body 27 is damaged or the like. Irrationality can be satisfactorily prevented and protected. In addition, by providing the temperature measuring body 27 including the upper temperature measuring body 27A and the lower temperature measuring body 27B in each of the above embodiments, the same effects as those described in the present embodiment can be obtained. Needless to say.

In addition, in this embodiment, although the some temperature measuring body 27 was provided in one protrusion part 26, only one temperature measuring body 27 is provided in one protrusion part 26, and temperature measurement is carried out. The sieve 27 may be configured so as to change the direction of the heated object 36 in the vertical direction at regular intervals using a motor or the like. Even in such a configuration, the temperature of the upper and lower positions of the object to be heated 36 can be measured by one temperature measuring body 27, and a relatively expensive temperature measuring body 27 can be formed by only one. Can be reduced.

According to the electric heating cooker of this invention, since the heat which a to-be-heated thing generate | occur | produces can be detected by a temperature measuring body through a top plate, the temperature of a to-be-heated object can be measured correctly.
