Technical Field

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

Prior art

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. The left heating portion is disposed on the left side of the top plate, the right heating portion is disposed on the right side, and the central heating portion is placed at the rear center. The electric heating cooker which has a heating part of a location is known. The said electric heating cooker is comprised so that the temperature sensor provided on the lower surface of a top plate may detect the temperature of a to-be-cooked object, such as food, and the cooker, such as a cooking pot or a frying pan. Accordingly, safety measures such as detecting the progress of cooking to perform heating control and proper cooking, or stopping the heating operation in order to prevent danger in advance when the temperature of the cooked or cooker suddenly rises, have.

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 said electric heating cooker has an opening formed in the upper surface of a box-shaped main body case, and a to-be-heated object is mounted on the top plate which covers this opening. Under the top plate, light emitters such as LEDs and lasers, light receiving elements, infrared sensors, and the like are provided, and light reflected from the light to be heated by the light emitters is reflected by the light receiving elements. And it converts the emissivity of the to-be-heated object converted from the output received by the light receiving element, and the temperature of a to-be-heated object by converting the temperature of the to-be-heated object from the light reception amount of an infrared sensor, It is comprised so that it may detect the exact temperature of a to-be-heated object (refer patent document 1).

[Patent Document 1] 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 under the top plate, the top plate is also heated. In the electric heating cooker that heats the heated object by itself and heats the heated object, first, the heating body generates heat to heat the top plate, and the temperature of the top plate is transmitted to the heated object as the order of temperature conduction. In order. In this method, since the heated object placed on the top of the top plate is heated from the bottom of the top plate, the top plate tends to have a higher temperature than the heated object, and the top plate is exposed to the top of the electric heating cooker. It is also conceivable that the temperature change is received.

In addition, in an electric heating cooker that heats the heated object by induction heating, a high frequency magnetic field is generated by a heating body, and an eddy current is generated in a cooker such as a cooking pot or frying pan, which is the heated object, to heat the heated object. . 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 the system which touched the top plate by the temperature sensor etc., and the temperature sensor which contacted the top plate detects the temperature of the top plate. Throw it away. However, the temperature of the top plate and the object to be heated does not necessarily match as described above, and the accuracy of the detection temperature is lacking due to the temperature difference between the top plate and the object to be heated.

In addition, as described in Patent Document 1, in the system 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. However, glass is generally difficult to transmit because it is easy to absorb infrared rays, and as the thickness of the glass becomes thicker, temperature detection by infrared rays passing through the glass also lacks accuracy. Moreover, there exist some things which are difficult to absorb infrared rays as a glass material, but there also exists a problem of cost, such as having sufficient intensity | strength in the nature of a top plate. Thus, in the electric heating cooker which measures the temperature of the to-be-heated object mounted on the top plate upper surface from below the top plate, the top plate is interposed between the to-be-heated object and an infrared sensor. For this reason, when the temperature of the to-be-heated object mounted on the upper surface of the top plate is detected by the infrared sensor provided under the top plate, there exists a problem that the exact temperature of a to-be-heated object cannot be detected by the influence of a 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 detect the temperature of the to-be-heated object mounted on the top plate with extremely high precision.

In order to achieve the above object, an electric heating cooker according to the present invention includes a top plate on which a heated object is placed, a frame provided on an outer periphery of the top plate, a body case in which the top plate and the frame are arranged on a top surface, and the blood A heating body that heats the heated object by an induction heating coil, an electric resistor, or the like, a control body that controls the output of the heating body, a blower that cools the heating parts provided in the main body case, and a temperature of the heated object It is provided with a temperature measuring body having a temperature detecting unit for measuring a, and provided with a projection protruding the upper side of the front side of the frame, and arranged to be inclined toward a predetermined angle upward from the horizontal with the temperature measuring body in the protrusion It is characterized by.

According to the electric heating cooking of this invention, since the temperature measuring body was inclined and arrange | positioned in the protrusion part which protruded the front upper part of an edge, the temperature of the to-be-heated object mounted on the top plate can be detected with high precision.

The electric heating cooker 1 includes a heating body 20 including a power supply unit, an electronic device, a microcomputer, etc., by performing heating cooking of the heated object 36 on the top surface 5 or the grill 9. The inside of the main body case 2 is heated by heat generating parts, such as an induction heating coil and an electrical resistor.

On the other hand, the electric heating cooker 1 in this embodiment is provided with the plurality of protrusions 26 which protruded the upper surface part of the front side of the frame 6 to predetermined dimension upward. Each projection part 26 is provided in the top plate operation part 16 which is closest to the circle line 7B, 7C of the front side in which the to-be-heated object 36 is mounted, as shown to FIG. 2, FIG. 3, FIG. . In addition, in the embodiment, the projections 26 corresponding to the circle lines 7B and 7C are shown, and the projections 26 corresponding to the circle lines 7A are not shown. The projections 26 may not be formed for each of the circle lines 7A, 7B, and 7C, but may form wide projections to correspond to the circle lines 7A, 7B, and 7C.

The projection part 26 is provided corresponding to each heating body 20, and in these projection part 26, the temperature measuring body 27 which can measure the temperature of the to-be-heated object 36 as shown in FIG. 3, FIG. And the light-emitting body 24 which shows the directing position of this temperature measuring body 27 are provided. The thermometers 27 are directed to the heated objects 36 placed on the circle lines 7A, 7B, and 7C, respectively. In addition, in FIG. 5, the figure which combined the thermostat 27 and the light-emitting body 24 is shown. Incidentally, the description of the light emitter 24 will be described later in detail.

Moreover, the display part 32 connected to the control body 34 is provided in the vicinity of the projection part 26, This display part 32 is provided in the inclined surface 30 on the opposite side of the projection part 26 formed in the opposite side to the inclined surface 28. As shown in FIG. have. The said display part 32 is comprised from the 7-segment LED which can display a letter, a figure, etc., a liquid crystal display, etc., and is made to display the temperature of the to-be-heated object 36 detected by the temperature measuring body 27. As shown in FIG.

Here, the temperature measurement body 27 has the temperature detection part 38 which consists of infrared sensors, and the temperature detection part 38 is able to detect the infrared rays which generate | occur | produce from the to-be-heated object 36. And the temperature measuring body 27 is able to measure the temperature of the to-be-heated object 36, without contacting the to-be-heated object 36 by measuring the temperature of the to-be-heated object 36 from the detected infrared ray. . Since the infrared rays generated from the heated object are detected, and the technique of measuring the temperature of the heated object from the detected infrared rays is conventionally known, a detailed description thereof will be omitted.

Further, the circle line 7B, 7C side of each of the protrusions 26 is formed with an inclined surface 28 which is inclined upward as being separated from the circle lines 7B, 7C, and further spaced apart from the upper end of the inclined surface 28. Therefore, it is formed in the mountain shape in which the inclined side surface 30 which inclines gently until it becomes a planar position with the top plate operation part 16 is formed. The inclined surface 28 is provided with a through hole 28A as shown in FIG. And the temperature measuring body 27 is inserted in the support part 29 from the inside of the projection part 26, and is fixed by the adhesive agent (not shown) etc. Moreover, since the inclined surface 28 is formed, even if the to-be-heated object 36, for example, a pot etc. collides, the impact is alleviated and it can prevent that a boiled product etc. flow.

The temperature detection part 38 of the temperature measuring body 27 is inserted in the through-hole 28A until it becomes roughly the same plane, and is exposed from the through-hole 28A, and aims at the outline center of the diameter of the to-be-heated object 36. FIG. That is, the infrared rays generated from the heated object 36 can be detected directly by exposing the temperature detecting portion 38 of the thermometer 27 to the through hole 28A of the inclined surface 28. The temperature measurement position of the object to be heated 36 is divided into 10 by the total height of the protrusions 26 and the lower part of the object to be heated 36. From 2 to 5 in the upward direction. In this case, the temperature measurement position of the to-be-heated object 36 is lower than a center part with respect to the total height of the to-be-heated object 36 mounted on the top plate 5, and from the lower end of the to-be-heated object 36, The predetermined dimension is set upward. That is, the temperature detection part 38 of the temperature measuring body 27 is directed from the horizontal (one dashed-dotted line of FIGS. 3, 4) to the solid line arrow range (the range of (theta) of FIGS. 3, 4) above a predetermined angle.

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 containing the temperature detection part 38 from being damaged by external force, have. 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. The protruding wall 31 extends from the lower end to the upper end of the inclined surface 28 at a predetermined width, and is provided at the center of the temperature measuring body 27 and the light emitting body 24. 26A is an adhesive agent which fixes the projection part 26 to the predetermined position of the top plate operation part 16. FIG.

Thus, the projection part 26 is provided correspondingly to the some heating body 20, and the temperature detection part 38 of the temperature measuring body 27 accommodated in this projection part 26 is angled upwards (theta) from horizontal. Tilt towards That is, the temperature detection part 38 of the temperature measuring body 27 measures the temperature of the heating object 36 slightly upward (in this case, near the bottom of a pot) from below. Thereby, even when there are few boils in a deep pot, a boil in a shallow pot, or many boils in a deep pot, the temperature of the boil in a pot can be measured reliably. Moreover, since the projection part 26 is provided correspondingly to each heating body 20, even when the heated object 36 is heated and cooked simultaneously by each heating body 20, each to-be-heated object 36 The temperature of can be measured simultaneously, and the usability can be greatly improved.

In addition, the projection part 26 can be restrained low in the case where the whole temperature measuring body 27 is protruded from the top plate 5, and at least the inadequacy such that the heated object 36 comes into contact with the projection part 26 is at least minimized. Can be suppressed. In addition, since the edge portion where the side surface and the bottom surface of the heated object 36 intersect is generally formed in an R shape, temperature measurement is difficult from the horizontal direction of the heated object 36. However, in the present invention, since the temperature measuring body 27 is inclined upward by a predetermined angle, the temperature can be measured at an angle that is approximately orthogonal to an R-shaped portion near the bottom of the heated object 36, and the pan is shallow. Even in a deep pot or the like, the temperature of a portion near the bottom of the heated object 36 can be measured reliably.

In addition, since the temperature measuring body 27 is provided upward in the projection part 26 by a predetermined angle, even when an article such as a spoon or chopsticks is placed between the temperature detecting part 38 and the object to be heated 36, it may be shielded. And the inadequacy which the temperature of the to-be-heated object 36 becomes impossible to measure can be avoided. Thereby, the temperature of the to-be-heated object 36 can be measured reliably. In particular, since the temperature detection unit 38 of the thermometer 27 is directed toward the user, the temperature of the user is measured when the object to be heated 36 is not placed on the top plate 5. Inadequacies such as discarding can also be prevented. Thereby, the temperature of the to-be-heated object 36 mounted on the top plate 5 can be detected with extremely high precision, and it is convenient.

Moreover, since the display part 32 is provided in the vicinity of each protrusion part 26, the temperature of the to-be-heated thing 36 in which the temperature displayed on the display part 32 was mounted on each circle line 7A, 7B, 7C is placed. It is convenient because we can grasp whether it is temperature clearly. Therefore, there is no mistake in the temperature which the display part 32 displays which temperature of the to-be-heated thing 36 is displayed. Moreover, you may make it the display part 32 display the character, the figure, etc. which show the abnormality of the electric heating cooker 1. As shown in FIG.

On the other hand, the light emitter 24 is housed in the projection 26 in which the temperature measuring body 27 is accommodated, as shown in FIGS. 4 and 5. The light emitter 24 is fixed to the projection portion 26 slightly upward (the predetermined angle θ) in the protrusions 26, similarly to the thermometer 27, and the thermometer 27 is heated. It is to emit light when the temperature of is measured. The light emitter 24 is composed of a non-heat-emitting light emitting element such as a light emitting diode, and the light emitted from the light emitter 24 is irradiated to the heated object 36.

The light irradiated from the light emitter 24 has a brightness that can be easily visualized at a position about 3 m to 5 m away from the object to be heated 36. This light-emitting body 24 is comprised so that the temperature measuring body 27 irradiates light to the part which is the same as the part which measures the temperature of the to-be-heated object 36, or its vicinity. In addition, although the protrusion wall 31 is provided only in the center of the protrusion part 26 in FIG. 5, when the protrusion wall 31 is provided in the both ends of the protrusion part 26, the effect as the protrusion wall 31 can be improved further. have.

In this way, since the light emitted from the light emitter 24 is irradiated to the same location or the vicinity of the location where the temperature measuring body 27 measures the temperature, the temperature measuring body 27 causes any heating object 36 to be irradiated. It is possible to visually recognize whether the temperature is measured or the temperature at which position is being measured. In addition, since the light emitter 24 emits light when the temperature measuring element 27 is measuring the temperature of the object to be heated 36, the user irradiates whether or not the user is measuring the temperature of the object to be heated 36. It is convenient to grasp. Therefore, even if a small obstacle such as a mug, a cup, a chopstick or a spoon is placed between the thermometer 27 and the heated object 36, it can be recognized and excluded by the irradiated light. The temperature of 36) can be measured satisfactorily.

In addition, since the induction heating coil does not generate red heat like the electric resistor, it is not known whether the heated object 36 is heated on the top plate 5. However, in the present invention, since the light to be heated (36) is irradiated with light from the light emitting body (24), when the user sees the heated object (36) to which the light emitting body (24) is irradiated, which object is to be heated It is convenient because it is easy to discriminate whether it is measuring (36).

In addition, by constituting the light emitting body 24 with non-heating light emitting elements such as light emitting diodes, the position where the light emitting body 24 irradiates light to the heated object 36 does not become warm. Thereby, even if the temperature measuring body 27 irradiates light to the same or near the location which measures the temperature of the to-be-heated object 36, the temperature measuring body 27 was heated by the heating body 20, The to-be-heated material The actual temperature of (36) can be measured accurately. Therefore, it is possible to prevent the thermal effect of the light emitted by the light emitter 24 on the temperature measurement of the heated object 36 in the temperature measuring body 27, and to accurately measure the accuracy of the temperature measurement measured by the temperature measuring body 27. It can be greatly improved.

In addition, the light emitting body 24 in this embodiment is controlled by the control body 34, and the brightness irradiated corresponding to the temperature of the to-be-heated object 36 which the temperature measuring body 27 measured changes so that it may change. The change in the brightness of the light-emitting body 24 is divided into three stages of weak light, medium light, and strong light, for example, by which the user can easily recognize the change in brightness. And the brightness of the light-emitting body 24 to the temperature (for example, +40 degreeC) which is hot when touched from the time when the heating of the to-be-heated object 36 starts is made into neutral light. In addition, the brightness of the light-emitting body 24 until the temperature of the to-be-heated object 36 reaches +400 degreeC or more, for example, makes it strong. In addition, the brightness of the light-emitting body 24 when the heated object 36 is kept in a warm state is set to weak light.

As described above, since the light emitter 24 changes the brightness of the light irradiated to the heated object 36 in response to the heating temperature of the heated object 36, the heating start of the heated object 36 and the heated object The boiling state of (36), the thermal insulation state, etc. can be known and it is convenient. In addition, the change of the brightness | luminance of the light-emitting body 24 is not limited to three steps, A change of two, four, and five steps may be sufficient. In addition, although the emission color of the light-emitting body 24 is considered to be red, yellow, green, blue, etc., for example, the light emission color of the light-emitting body 24 is preferably opposite to the surface color of the object to be heated 36.

In addition, as the object to be heated (including the direction of the light emitting body 24) of the temperature measuring body 27, a frying pan having a low height, a pot having a different height such as a high pot or a low pot, It corresponds to a wider cooker. In this case, as the height to which the temperature measuring body 27 is directed, the height is between 2 and 5 splits, preferably between 2 and 3 splits, from the lower part to the upper direction at the height of the general heated object 36 such as a pan. It's good to orient yourself. In addition, since the food is present at the bottom of the cooker, it is possible to measure the temperature of a part 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. If it is higher than this, it is difficult to cope with a relatively low cooker such as a frying pan. In particular, the connection between the bottom surface and the side surface of the cooker is generally formed in an R shape as the directing point of the light emitter 24, and when light is irradiated to the R-shaped portion, it becomes difficult to visually recognize the light. This is because a low pot, a low frying pan, or the like cannot irradiate the light to be heated 24 with the light to be heated 36.

Example 2

The electric heating cooker 1 in this embodiment has the structure substantially the same as the above-mentioned embodiment. The other parts will be described below. FIG. 6 is a front view of the object to be heated 36 of the protrusion 26 of the electric heating cooker 1 according to the present embodiment. In Example 2, the light emitters 24A of the plurality of colors are provided for the first embodiment, and the controller 34 controls the light emission order of the light emitters 24A of the plurality of colors. It is configured similarly. In the embodiment, the light emitter 24A is composed of a plurality of light emitting diodes, for example, red 24a, yellow 24b, green 24c, blue 24d, and the like. It is connected to the sieve 34.

The controller 34 is configured to emit one of the light emitters 24A among the plurality of light emitters 24A in response to the heating temperature of the heated object 36. In this case, when the temperature measuring body 27 measures the temperature of the to-be-heated object 36, the control body 34 emits the blue light-emitting body 24d, and heats the to-be heated object 36, for example. ), The green light emitter 24c emits light when the temperature reaches a hot feeling (for example, about + 40 ° C. or lower). In addition, when the temperature of the to-be-heated object 36 is from +40 degreeC to boiling, for example, the control body 34 emits the red light-emitting body 24A, and heat-retains the to-be-heated object 36, for example. In this case, the yellow light-emitting body 24b is emitted. The light emitted from the light emitter 24A is irradiated to a predetermined position on the side of the heated object 36.

Thus, when the temperature of the to-be-heated material 36 which the temperature measuring body 27 measures reaches the predetermined temperature, the control body 34 selects any one of the light-emitting bodies 24A which have several light emission color. It is made to emit light in a luminescent color. Thereby, a user can know the heating state and cooking state of the to-be-heated object 36 also in a distant place, and it is convenient.

Example 3

The electric heating cooker 1 in this embodiment has a structure substantially the same as the above-mentioned embodiment. The other parts will be described below. In the third embodiment, a single light emitter 24 is provided in the same manner as in the first embodiment, and the control unit 34 controls the light emission of the single color light emitter 24, and the others are configured similarly to the first embodiment. . In the embodiment, the light emitter 24 is composed of only red of a plurality of light emitting diodes such as red, yellow, green, blue, and the like. The light emitter 24 is connected to the controller 34. In addition, the light emission color of the light emitter 24 is preferably opposite to the surface color of the heated object 36.

And the control body 34 makes the light-emitting body 24 light-emit when the temperature of the to-be-heated object 36 which the temperature measuring body 27 measures becomes more than predetermined value. In detail, the control body 34 is not hot when the temperature measuring body 27 is measuring the temperature of the heated object 36, even if the heated target object 36 is touched (for example, + 40 ° C. or lower). In this case, the light emitter 24 is not emitted. In addition, the control body 34 emits the light emitter 24 when the temperature of the object to be heated (for example, + 40 ° C. or more) is felt when the object to be heated is touched by hand, and light is emitted to the side of the object to be heated 36. Investigate Thereby, a user can know the cooking state of the to-be-heated object 36 also in a distant place, and it is convenient.

In addition, although the light emitting body 24 was comprised by the non-heating light emitting element, such as a light emitting diode in the Example, the light emitting body 24 is not limited to a light emitting diode, The laser light as a non-heating light emitting element may be sufficient. In this case, letters (for example, letters during heating, boiling, steaming, warming, etc.) can be irradiated on the side surface of the object to be heated 36 with laser light, which is convenient. In addition, the heating temperature of the object to be heated 36 can be displayed on the side of the object to be heated 36 in real time by letters. In addition, when a character such as heating, boiling, steaming, or keeping warm, which is irradiated to the side surface of the heated object 36 by laser light, is irradiated to the wall of the kitchen where the electric heating cooker 1 is installed, the user Even in the far field, cooking contents can be grasped with large letters, making it more convenient.

In addition, although the light emitter 24 and the temperature measuring body 27 are provided in the protrusion part 26, the light emitting body 24 and the temperature measuring body 27 in the protrusion part 26 are attached to one metal plate, for example, and can be interlocked. It is possible to adjust the directing angles of the light emitting body 24 and the temperature measuring body 27 from the outside. In this case, the light irradiated by the light emitter 24 is adjusted in accordance with the shape of the object to be heated 36 (by adjusting the angle of the metal plate, the position of the light irradiated by the light emitter 24 is adjusted). Thereby, even if the shape of the to-be-heated object 36 is extremely thin, or the shape of R-shaped part is extremely large, etc., it is convenient to be able to reliably measure the temperature of the to-be-heated object 36, for example.

According to the electric heating cooking of this invention, since the temperature measuring body was inclined and arrange | positioned in the protrusion part which protruded the front upper part of an edge, the temperature of the to-be-heated object mounted on the top plate can be detected with high precision.
