Description

  The present invention relates to a heating cooker having an induction heating type cooking device (hereinafter referred to as an IH cooking device), a halogen heater, or the like as a heat source.

  Conventionally, as this type of heating cooker, a top plate, a temperature detection unit that detects the temperature of a pan (corresponding to a heating container) placed on the top plate, a heating unit, and input to the heating unit What is provided with the display means which displays the heating input setting level corresponded to the electric power which is (for example, refer patent document 1) is known.

  The conventional temperature detection unit is arranged at the center of the back surface of the top plate on which the pan is placed, and is configured to detect the bottom center temperature of the pan by heat conduction through the top plate. Then, when the temperature detected by the temperature detector becomes a predetermined value or more, the heating input setting level to the heating means is lowered. In addition, the display unit shifts to a display corresponding to the reduced heating input setting level.

JP-A-8-270957 (first page, FIG. 1)

  However, a heat-resistant insulating material is usually used for the top plate of this type of cooking device. For this reason, when the temperature of the pan is detected by heat conduction through the top plate, there is a problem that the detected temperature change is delayed with respect to the actual temperature change of the heated object inside the pan. Further, in the conventional cooking device as described above, there is a high possibility of giving a large error in temperature measurement due to the properties (material, shape, etc.) of the pan. That is, the temperature rise gradient varies depending on the difference in thermal conductivity depending on the material and thickness of the pan. In addition, in a warped pan with a concave pan bottom, the pan bottom does not touch the top plate, so a large error occurs in temperature measurement, and it is difficult for the temperature detector to detect the exact temperature of the heated object in the pan. .

  For this reason, the display means in the conventional cooking device cannot display corresponding to the temperature of the object to be heated in the pan, and can only display the heating input setting level of the heating means.

  The present invention has been made to solve such a problem, and can notify the state of an object to be heated in a heating container without being affected by the material and shape of the pan, and further demonstrate the function. The purpose is to provide a cooking device that enables cooking.

A heating cooker according to the present invention has a top plate for placing a heating container, a heating cooker body that cooks an object to be heated in the heating container by a heating means, and vibration transmitted to the heating cooker body A vibration sensor for detecting the level, and a notification means capable of notifying two or more forms of the boiling state of the object to be heated in the heating container based on the output of the vibration sensor.
A heating cooker main body having a top plate for placing the heating container, cooking the object to be heated in the heating container by heating means, and a vibration sensor for detecting a vibration level transmitted to the heating cooker main body; A demonstration setting means capable of switching from the normal mode to the demonstration mode; and an input setting display means for displaying a heating input setting level for the heating means in the normal mode,
When the demonstration mode is selected by the demonstration setting means, the input setting display means switches to a vibration level display means for displaying the state of vibration transmitted to the heating cooker body based on the output of the vibration sensor. It is what I did.

  The cooking device according to the present invention is capable of detecting an accurate boiling state by a vibration sensor, and is demonstrated at the time of over-the-counter sales through a level meter that can display the boiling state. A demonstration effect can be obtained, which can lead to a sales promotion effect.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of a heating cooker according to the invention will be described with reference to the accompanying drawings.
Embodiment 1 FIG.
1 is a cross-sectional view showing a state where a pan is placed on a heating cooker according to Embodiment 1. FIG. Moreover, FIG. 2 is a top view which shows the state which mounted the pan in the heating cooker which concerns on Embodiment 1. FIG.

  1 and 2, the heating cooker according to this embodiment includes a current-carrying coil 1 that is a heating unit housed in a box-shaped housing 2 and wound in a spiral shape in one plane. A flat top plate 3 placed close to the top of the energizing coil 1 and on which the pan 6 serving as a heating container is placed; a control means 4 for increasing or decreasing the amount of high-frequency alternating current flowing through the energizing coil 1; An operation panel 5 is provided at the front end of the upper surface of the housing 2 and allows input of a signal for starting / stopping heating and a signal for setting the temperature of the object to be heated.

  Here, a transparent heat-resistant insulating material such as crystallized glass is used for the top plate 3. In addition, on the top surface of the top plate 3, the pan 6 in which the object to be heated is accommodated can be placed at a position facing the energizing coil 1. The pan 6 is generally made of a metal material such as iron, and is placed in an alternating magnetic field formed around the coil as the energizing coil 1 is energized by an instruction from the operation panel 5.

  Further, the heating cooker according to the first embodiment includes a vibration sensor 7 on the rear rear surface of the top plate 3. The vibration sensor 7 detects vibration caused by bubbles generated by boiling of the heated object in the pan 6 placed on the top plate 2. The vibration intensity signal which is the output of the vibration sensor 7 is smoothed by the vibration signal smoothing means 8. FIG. 3 is a schematic view showing a waveform smoothed by the vibration signal smoothing means 8. The horizontal axis is the output of the vibration smoothing means 8, and the horizontal axis is time. The output of the vibration signal smoothing means 8 is input to the control means 4. When detecting the boiling state from the input waveform, the control means 4 outputs a signal for lowering or stopping the heating input setting level to the energizing coil 1.

  On the other hand, setting information from the operation panel 5 and output information from the control means 4 are displayed and notified by the display panel 9. More specifically, as shown in FIG. 2, the heating input setting level for the energizing coil 1 is set by the switch 5a on the operation panel 5, and the setting level is displayed on the input setting display means 9a. The input setting display means 9a shown in FIG. 2 can perform eight-step input setting and display.

  Further, the display panel 9 has a boiling display means 9b and a large boiling display means 9c. These two display means are notification means capable of notifying two or more forms of the boiling state of the object to be heated based on the output of the vibration sensor 7. These boiling display means 9b and large boiling display means 9c display the boiling state in the pan 6 detected by the control means 4 analyzing the waveform smoothed by the vibration signal smoothing means 8.

FIG. 4 is a plan view showing the state of the pan when the boiling display means 9b is lit, and FIG. 5 is a plan view showing the state of the pan when the large boiling display means 9c is lit. As shown in FIG. 4, during the initial boiling, many fine bubbles are generated and increased in the pan. Along with this, the vibration level also increases, but the boiling display means 9b lights up in the vicinity of the time when the vibration level reaches the maximum value (see “boiling” in FIG. 3). On the other hand, as shown in FIG. 5, when the boiling continues and the temperature rises, large bubbles are generated, and accordingly, the vibration level is slightly reduced via the maximum value. The large boiling display means 9c is lit in such a state that the vibration level is slightly decreased via the maximum value (see “large boiling” in FIG. 3).
In this embodiment, the display means has two stages. However, the display means may be set in a plurality of stages according to the output of the vibration signal smoothing means 8 and the analysis ability of the control means 4.

  Reference numeral 9d denotes a speaker (sounding means) that generates a reception sound when the switch 5a is pressed and a notification sound when boiling and large boiling are detected. As the notification means for reporting two or more forms, a display means that appeals to the eye like the boiling display means 9b and the large boiling display means 9c may be used, or a sounding means that appeals to the hearing like the speaker 9d.

  Next, the operation of the heating cooker according to the first embodiment will be described. First, the pan 6 in which the object to be heated is accommodated is placed on the top plate 3. And cooking selection, such as target temperature setting, is performed from the operation panel 5, and the setting value is displayed on the input setting display 9a. Subsequently, a start signal is input from the operation panel 5, and cooking of the object to be heated starts. In response to this start signal, the control means 4 and the vibration sensor 7 start operating. The control means 4 energizes the energizing coil 1 with a current amount of high-frequency alternating current that matches the temperature setting. The entire pan 6 is heated as a heating source by the action of the eddy current flowing inside the energizing coil 1, and the object to be heated in the pan 6 is heated.

  As the object to be heated is heated, fine bubbles are generated at the bottom of the pan from the vicinity where the water temperature in the pan exceeds 80 ° C. The bottom of the pot is vibrated by an impact when the bubbles are released from the bottom of the pot, and the vibration is transmitted to the top plate 3 by this exciting force, and the output of the vibration sensor 7 starts to rise gradually. The increase in the vibration intensity signal becomes maximum when the water temperature is around 95 ° C. At 100 ° C. when boiling completely, the bubbles from the bottom of the pot become larger and the excitation force when the bubbles are released from the bottom of the pot is weakened, so the output of the vibration sensor 7 tends to decrease. The vibration intensity signal from the boiling sensor 7 is an alternating half-wave waveform, and an output whose peak value increases with the vibration intensity is obtained. The raw waveform of the boiling sensor 7 is smoothed by the vibration signal smoothing means 8 to obtain the waveform shown in FIG.

  The boiling display means 9b on the display panel 9 lights up and displays when the signal at which the vibration intensity reaches the maximum, that is, around 95 ° C. is detected. For example, only the display unit on the side where the pan is placed (in the example, the right side) is operated. Further, a notification sound is generated by the speaker 9d. If the user does not perform the stop operation at this time and the operation is continued, the object to be heated is overheated due to the energization of the heating coil 1. As described above, the signal intensity that has been smoothed gradually decreases in the direction of boiling up to 100 ° C. due to overheating. The control means 4 detects this, turns on the large boiling display means 9c, generates a notification sound, and interrupts the energization of the heating coil 1.

  Further, after the boiling display means 9b is turned on, the energization rate to the heating coil 1 may be lowered. Furthermore, the energization rate to the heating coil 1 may be lowered even after the large boiling display means 9c is turned on.

  As described above, the cooking device according to this embodiment can use the vibration sensor 7 to enable highly accurate boiling detection and display without being affected by the material and shape of the pan. . Furthermore, a plurality of display devices capable of displaying the transition of the boiling state enables more accurate state detection linked to the boiling state of the object to be heated that is visible. For this reason, the apparatus can be stopped at a necessary temperature, for example, an optimum temperature of about 80 ° C. for putting tea, and the usability can be improved.

  In this embodiment, the case where the vibration sensor 7 is disposed on the rear rear surface of the top plate 3 has been described. However, the present invention is not limited to this. That is, the vibration sensor 7 only needs to be able to detect the vibration level transmitted to the heating cooker body constituted by the housing 2 and the top plate 3, and is disposed either inside or outside the heating cooker body. May be.

Embodiment 2. FIG.
FIG. 6: is a top view which shows the state which mounted the pan in the heating cooker which concerns on Embodiment 2 of this invention. FIG. 7: is sectional drawing which shows the state which mounted the pan in the heating cooker which concerns on Embodiment 2 of this invention. In addition, the same code | symbol is attached | subjected to the same or equivalent part as Embodiment 1, and description is abbreviate | omitted.

  As shown in FIG. 6, the heating cooker according to this embodiment has a demo setting means 5 b on its operation panel 5. When the operator operates the demonstration setting means 5b, the cooking device can be switched from the normal mode to the demonstration mode. The demonstration mode is a mode used for demonstration sales at a store, for example.

  The display panel 9 is provided with a speaker 9e. As shown in FIG. 7, the speaker 9 e is connected to the vibration sensor 7 via the control means 4 and the vibration signal smoothing means 8. This speaker 9e constitutes a first notification means that detects and notifies the boiling state of the object to be heated together with the control means 4.

  Further, the display panel 9 functions as an input setting display means for displaying the heating input setting level for the heating means 1 in the normal mode, and in the demonstration mode, the vibration transmitted to the main body of the cooking device based on the output of the vibration sensor 7 is displayed. A level meter 9g functioning as vibration level display means (second notification means) for displaying the state is provided. That is, the level meter 9g is connected to the switch 5a for setting the heating input setting level to the energizing coil 1 via the control means 4 as shown in FIG. The level meter 9g is also connected to a raw waveform output means 7a capable of directly transmitting the output from the vibration sensor 7 to the level meter 9g without passing through the vibration signal smoothing means 8. The level meter 9g is configured to display any output on the switch 5a side or the raw waveform output means 7a side by switching the connection.

  Next, the operation will be described. First, in the normal mode, the level meter 9g functions as input setting display means as described above. That is, the level meter 9g is connected to the switch 5a side. For this reason, when the heating input setting level from the switch 5a to the energizing coil 1 is set, the setting level is displayed on the level meter 9g. On the other hand, when heating is started, as the object to be heated is heated, vibration when bubbles are released from the bottom of the pan starts to be transmitted to the main body of the cooking device. This vibration is detected by the vibration sensor 7. The output of the vibration sensor 7 is smoothed to a state where it can be input to the control means 4 by the vibration signal smoothing means 8 and is input to the control means 4. The control means 4 monitors the state of the object to be heated based on the smoothed output of the vibration sensor 7 and notifies the speaker 9e when a boiling state is detected.

  Next, the case of the demonstration mode will be described. When the demonstration mode is selected by the demonstration setting means 5b, the level meter 9g functions not as an input setting display means but as a vibration level display means as described above. That is, the level meter 9g can be switched to the raw waveform output means 7a side. The raw waveform output means 7a does not pass through the vibration signal smoothing means 8 as described above. For this reason, the level meter 9g can display the state of the output of the vibration sensor 7 that has not been smoothed by the vibration signal smoothing means 8 via the raw waveform output means 7a. Even in this demonstration mode, the boiling state is notified by the speaker 9e in the same manner as in the normal mode. That is, with the start of heating, vibration begins to be transmitted from the bottom of the pan to the main body of the cooking device, and this vibration is detected by the vibration sensor 7. The output of the vibration sensor 7 is smoothed to a state that can be input to the control means 4 by the vibration signal smoothing means 8 and then input to the control means 4. The control means 4 monitors the object to be heated based on the smoothed output of the vibration sensor 7, and notifies the speaker 9e when a boiling state is detected.

  Next, the display of the level meter 9g will be described in detail with reference to FIGS. FIG. 8 is a diagram showing the raw waveform of the vibration sensor 7 and the waveform after smoothing. FIG. 9 is a conceptual diagram showing a state of external vibration input to the cooking device. In FIG. 8, the horizontal axis represents time, and the vertical axis represents vibration intensity. The vibration intensity on the vertical axis is divided into 8 levels. In FIG. 8, the waveform of the raw waveform output means 7a is the half-wave alternating vibration intensity waveform shown in the vibration raw waveform 50a in the figure. This raw waveform is converted into a vibration smooth output waveform 50b by the vibration signal smoothing means 8. The vibration raw waveform 50a is not smoothed and outputs a real-time vibration waveform. Therefore, when an external vibration is applied as an external vibration input by, for example, tapping the top plate 3 by hand as shown in FIG. 9, a peak waveform as shown at 50c at the time of external vibration input in FIG. 8 is obtained. It is done. However, the vibration smooth output waveform 50b is configured not to appear as a large vibration waveform because the peak waveform at the time of external vibration input is also smoothed and averaged. In the demonstration mode, what is displayed on the level meter 9g is the level of the vibration intensity corresponding to the vibration raw waveform 50a of FIG.

  For example, when external vibration is input as shown in FIG. 9, the raw waveform output means 7a detects the peak value and displays the level on the level meter 9g. In the example of FIG. 8, since the signal exceeding the vibration intensity level 7 is detected due to the external vibration, in FIG. 9, the light is displayed up to the level 7 of the level meter 9g. The output of the raw waveform output means 7a can display external vibrations and the like in real time. For this reason, at the time of demonstration, the presence of the vibration sensor 7 can be appealed and the movement becomes dynamic and effective.

  On the other hand, the vibration smoothing output waveform 50b smoothed by the vibration signal smoothing means 8 is input to the control means 4 that detects the boiling state of the object to be heated. Since the vibration smooth output waveform 50b is configured such that the peak waveform does not appear as shown in the case of the external vibration input 50c, malfunction due to the presence of the peak waveform can be prevented.

  In this embodiment, the case where the level meter 9g is used as the second notification means has been described. However, the present invention is not limited to this. For example, a sound corresponding to the vibration intensity is output from the speaker 9e. May be. Furthermore, the display of the vibration raw waveform can be displayed on the level meter 9f on the side where the pan is not placed (left side in FIG. 9). Therefore, even if the pan 6 is placed only on one side (right side in FIG. 9) and the demo setting means 5b is turned on and operated, both level meters 9g and 9f can display vibrations due to external input vibration or the like. Become.

  Further, in the demonstration mode, the vibration meter waveform may be displayed on the level meter 9g even when no input is made to the heating means 1, that is, when the heating means 1 is inactive. By adopting such a configuration, it is not necessary to boil hot water, so demonstration sales at stores can be facilitated.

  Since this embodiment is configured as described above, the vibration sensor 7 can detect an accurate boiling state. For this reason, by providing a device such as a level meter capable of displaying the boiling state and demonstrating at the time of over-the-counter sales, a persuasive demonstration effect can be obtained for the customer, which can lead to a sales promotion effect. In addition, when the demonstration mode is switched by the demonstration setting means, it is not necessary to provide a special demonstration sales display device in order to display the demonstration using the existing display device. For this reason, there is an effect that no part cost is required.

  In this embodiment, the case where the demo setting means 5b is provided has been described. However, the present invention is not limited to this, and may be realized by pressing a plurality of combinations of existing switches without providing a special switch. .

Embodiment 3 FIG.
FIG. 10 is a plan view showing a case where the pan placed on the right side of the top plate is in a boiling state. In the above-described second embodiment, the case where the speaker 9e is used as the first notification unit that notifies the boiling state of the object to be heated has been described. In this embodiment, a case where a part of the level meter 9g is used as the first notification means will be described. This embodiment is a modification of the above-described second embodiment, and the same or corresponding parts as those of the second embodiment are denoted by the same reference numerals and description thereof is omitted.

  That is, when the right energizing coil 1 provided on the back side of the top plate 3 is in an active state as shown in FIG. 10, the control means 4 uses the vibration smooth output waveform 50b shown in FIG. Monitor the boiling state of things. Then, a time point near the maximum value of the vibration smoothing output waveform 50b and / or a point falling from the maximum value is detected as a boiling state and displayed on a part of the level meter 9g. The display using a part of the level meter 9g is performed by blinking the level 8 of the level meter 9g. For example, in the demonstration mode, the output of the raw waveform output means 7a is displayed on the level meter 9g according to the eight levels of vibration intensity shown in FIG. 8, and when boiling is detected, the level of the level meter 9g is displayed. Boiling can be notified by blinking 8. At this time, level 8 of the level meter 9g may be blinked and sound may be generated from the speaker 9e. Visibility can be improved by setting it as the above structures.

Embodiment 4 FIG.
FIG. 11 is a plan view of a cooking device provided with smooth vibration level display means. In the above-described second embodiment, the case has been described in which both the level meters 9g and 9f are used as the second notification means for notifying the state of vibration transmitted to the heating cooker body. In the fourth embodiment, a case will be described in which only one level meter 9g is used as the second notification means and the other level meter 9f is used as the smooth vibration level display means. That is, the level meter 9f of the heating cooker according to this embodiment is configured to display the level of the vibration smooth output waveform 50b of FIG. 8 according to the eight levels of vibration intensity. On the other hand, the level meter 9g displays the level of the vibration raw waveform 50a shown in FIG.

  As a result, since the level meter 9f of the heating cooker according to this embodiment performs level display according to the vibration smoothing output waveform 50b, the level display gradually increases with the start of heating, but the external vibration 50c is displayed. Even if given, it does not react with sensitivities. This is in contrast to the level meter 9g that is sensitive to the external vibration 50c. FIG. 11 is a plan view of the cooking device immediately after the external vibration 50c is input, but the display of the level meter 9f is stable at level 2 even by the input of the external vibration 50c shown in FIG. The display of the level meter 9g is lit up to level 7.

  Therefore, by making it possible to compare both level meters 9g and 9f during the demonstration, the presence of the vibration sensor can be appealed to the customer by the level meter 9g, and the level meter 9f can detect boiling with high accuracy without causing malfunction. There is an effect that it can be explained.

Embodiment 5. FIG.
FIG. 12: is sectional drawing which shows the state which mounted the pan in the heating cooker which concerns on Embodiment 5 of this invention. FIG. 13 is a graph showing the output of the vibration signal smoothing means according to the fifth embodiment. In addition, the same code | symbol is attached | subjected to the same or equivalent part as the above-mentioned embodiment, and description is abbreviate | omitted.

  The heating cooker according to this embodiment includes a cooling fan 10 as a blowing means for preventing heating of the energizing coil 1 inside. The cooling fan 10 operates according to a control command from the control means 4. In the present embodiment, after receiving a heating start command to the heating means 1, first, only the cooling fan 10 is energized (activated) for a predetermined period, and then the energization (activation) to the energizing coil 1 is performed.

  Due to the operation of the cooling fan 10, the rotational speed component is transmitted to the housing 2, and the housing 2 vibrates. This vibration is detected by the vibration sensor 7 and detected as a signal intensity. At this time, since the vibration of only the cooling fan 10 can be detected by operating the cooling fan 10 alone, the vibration level of the cooling fan 10 can be checked. That is, since the vibration intensity cannot be detected when the fan does not operate due to the disconnection of the cooling fan 10, this is detected and an error is displayed, and the operation is stopped without shifting to the energization of the energizing coil 1. Further, even when the vibration of the cooling fan 10 is larger than the allowable output (see FIG. 13), an error is displayed as a fan failure, and the operation is stopped without shifting to the energization of the energizing coil 1. The error display can be displayed, for example, by blinking all level displays of the level meter 9g. In this case, the level meter 9g corresponds to warning notification means.

  With the above configuration, the heating cooker according to this embodiment can determine the failure of the blowing means with a simple configuration and prevent the energization coil 1 from being overheated.

  In this embodiment, the case where the energizing coil 1 is deactivated for a predetermined period and only the cooling fan 10 is activated has been described. However, the present invention is not limited to this, and only the frequency band of the blower means 10 is extracted by Fourier transform or the like while the energizing coil 1 is activated for the predetermined period, and it is confirmed that there is no abnormality. You can also do it. Further, by setting the predetermined period to a short period after the activation of the energizing coil 1 and the air blowing means 10 and before the start of boiling, the cooling fan 10 is activated with both the energizing coil 1 and the cooling fan 10 activated. You can also check for any abnormalities.

  Furthermore, even within the allowable vibration range of the cooling fan 10, the vibration level may vary. In such a case, the detection threshold for boiling vibration can be changed according to the fan vibration intensity. By changing the threshold value, accurate vibration detection and boiling detection can be made possible.

  The present invention is particularly useful when used in a cooking device having an induction heating (hereinafter referred to as IH cooking device) type or a halogen heater as a heat source.
