Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat cooker with a temperature sensor for detecting the temperature of a cooking pot.

[0002]

2. Description of the Related Art Conventionally, in a thermal cooker with a temperature sensor, when the temperature sensor is brought into contact with the bottom of the cooking pot to sense the temperature of the cooking pot and the temperature sensed by the temperature sensor rises above the cut temperature. There is a type in which a temperature cut mode is set in order to prevent the burning due to overheating and the overheating of the cooking pot by closing the shutoff valve to shut off the fuel supply path and extinguishing the fire.

[0003]

However, in the conventional heat cooker with temperature sensor, when the burner combustion flame fluctuates due to the pan swinging during the cooking, the cooker lifts the cooking pan and stirs the cooking pan during use. There is a possibility that the temperature sensed by will rise above the cut temperature. In that case, even if the temperature of the cooking pot has not yet risen to the cut temperature, the temperature cut mode operates and the shutoff valve closes to automatically extinguish the fire, resulting in inconvenience.

Therefore, it is conceivable to delay the temperature cut until a predetermined time (for example, 10 seconds) elapses after the temperature sensed by the temperature sensor reaches the cut temperature so that the pan can be shaken. There is a problem that it will be delayed until you are not shaking, and that charring and overheating of the cooking pot will progress.

It is an object of the present invention to provide a thermal cooker with a temperature sensor, which automatically determines whether or not a pan is being shaken and prevents automatic fire extinguishing in a temperature cut mode during shaking of the pan to improve usability. And

DESCRIPTION OF THE PREFERRED EMBODIMENTS A thermal cooker with a temperature sensor according to the present invention will be described based on the embodiments shown in FIGS. 1 to 4
FIG. 3 is a diagram showing a first embodiment according to claim 1 of the present invention. FIG. 1 is a schematic diagram showing a main part of a table cooker with a temperature sensor, and FIG. 2 is a perspective view showing a table cooker with a temperature sensor.

A table cooker 1 with a temperature sensor is a temperature sensor-added heat cooker according to the present invention, and includes a gas burner 2, a gas supply passage 3, an electromagnetic gas valve 4 and a computer 5. The gas burner 2 is the heating means of the present invention, and heats the cooking pot 6 by burning a mixture of fuel gas and combustion air.

The gas supply passage 3 is the fuel supply passage of the present invention and supplies the fuel gas to the gas burner 2. Gas valve 4
Is an opening / closing means of the present invention, which is interposed in the gas supply path 3 to hold the valve open during energization (on) and stop energization (off).
When it is done, it closes.

The computer 5 is the control means of the present invention, and is a fire extinguishing button 7 for controlling ignition and extinguishing of the gas burner 2.
And a temperature sensor 8 such as a thermistor that abuts on the bottom of the cooking pot 6 to detect the temperature of the bottom of the cooking pot 6, selection and reset of the temperature cut mode, and multi-step cut temperatures of the temperature cut mode ( High cut temperature, high high cut temperature, and low cut temperature) Ts are connected to a setting device 9 for selecting arbitrarily.

The computer 5 contains a measuring circuit 10, a memory circuit 11, an arithmetic circuit 12 and a judging circuit 13. The measuring circuit 10 is the measuring means of the present invention,
A measurement start temperature Tf (for example, 2 which is lower than the cut temperature Ts (for example, high cut temperature 250 ° C.) selected by the setter 9)
The temperature Tn sensed by the temperature sensor 8 is measured at regular intervals (for example, 1 second) after the temperature sensed by the temperature sensor 8 rises above 30 ° C.). The memory circuit 11 is the memory means of the present invention, and stores the temperature Tn sensed by the temperature sensor 8 measured by the measuring circuit 10 at regular intervals.

The arithmetic circuit 12 obtains the first temperature difference ΔT1 between the maximum value Tmax and the minimum value Tmin of the latest five measured values measured by the measuring circuit 10, and at the same time, the fifth measured value T
A second temperature difference ΔT2 between n and the first measured value Tn-4 is obtained. The determination circuit 13 determines whether or not the first temperature difference ΔT1 calculated by the calculation circuit 12 is greater than or equal to the reference temperature difference ΔTs (for example, 10 ° C.), and whether the second temperature difference ΔT2 is greater than or equal to 0 ° C. Determine whether or not.

Here, according to the result of an experiment in which the temperature rising rate of the temperature sensed by the temperature sensor 8 is tested, the temperature at which the temperature sensed by the temperature sensor 8 rises in 5 seconds is 6.5 when the cooking pot 6 is cooked empty. If the oil is contained in the cooking pot 6 at ℃, the rise is less than that. In the case of shaking the pot, the temperature sensed by the temperature sensor 8 generally rises by 5 ° C. or more in 1 second.

FIG. 4 is a flow chart showing an example of the operation of the computer 5. First, it is determined whether or not the temperature cut mode is set (step S1). When the temperature cut mode is not set (No), the control of step S1 is performed.

In step S1, the temperature cut mode is set, and, for example, when the temperature sensed by the temperature sensor 8 reaches 250 ° C., the high cut mode is set in which the gas valve 4 is closed to automatically extinguish the fire (Yes). At this time, the sensed temperature Tn of the temperature sensor 8 is the measurement start temperature (for example, 230
C) Tf or higher, that is, Tn ≧
It is determined whether it is Tf (step S2). When Tn ≧ Tf is not satisfied (No), the control of step S1 is performed.

In step S2, when Tn ≧ Tf (Yes), it is determined whether or not a fixed time (for example, 1 second) has elapsed since the previous measurement of the sensed temperature Tn (step S3). No fixed time has passed (No)
At this time, the control of step S3 is performed.

In step S3, when a certain time has elapsed (Yes), the temperature Tn sensed by the temperature sensor 8 is measured and stored (step S4). Next, it is determined whether five or more measured values are stored (step S
5). 5 or more measurement values are not stored (No)
At this time, the control of step S3 is performed.

In step S5, when five or more measurement values are stored (Yes), the first temperature difference ΔT1 between the maximum value Tmax and the minimum value Tmin among the five measurement values is obtained (step S6). ), The first temperature difference ΔT1 is the reference temperature difference ΔT
Whether or not it is larger than s (for example, 10 ° C.), that is, Δ
It is determined whether T1≥ΔTs (step S7). ΔT
When 1 ≧ ΔTs (Yes), it is determined to be a pan swing, the temperature cut is avoided, and the oldest measured value Tn-4 is deleted (step S8). Then return.

In step S7, when ΔT1 ≧ ΔTs is not satisfied (No), {fifth measured value (Tn)}-{1
Second measurement value (Tn-4)} = second temperature difference ΔT2 is obtained (step S9), and it is determined whether the second temperature difference ΔT2 is 0 ° C. or more, that is, ΔT2 ≧ 0 ° C. ( Step S10). When .DELTA.T2 .gtoreq.0.degree. C. is not satisfied (No), the control of step S8 is performed.

In step S10, when ΔT2 ≧ 0 ° C. (Yes), it is determined that the cooking pot 6 is in normal use and the temperature cut mode is activated. Then, whether the temperature sensed by the temperature sensor 8 has risen above the cut temperature Ts (eg, 250 ° C.), that is, T
It is determined whether n ≧ Ts (step S11). Tn ≧
When it is Ts (Yes), the gas valve 4 is closed to automatically extinguish the fire (step S12), and the control ends.

In step S11, when Tn ≧ Ts is not satisfied (No), the control of step S8 is performed.

The operation of the table stove 1 with the temperature sensor will be described with reference to FIGS. First, the gas valve 4 is opened by pressing the point extinguishing button 7, and when the ignition is performed by an ignition device (not shown), the gas burner 2 starts combustion. Further, setting or resetting of the temperature cut mode is selected by the setter 9, and high cut mode or low cut mode is selected to set the cut temperature Ts.

A case where the high cut mode is selected will be described. As the cooking pot 6 is heated by the gas burner 2, the temperature sensed by the temperature sensor 8 also rises. Therefore, the temperature Tn sensed by the temperature sensor 8 is equal to the measurement start temperature Tf.
(Eg 230 ° C). In this way, when the temperature Tn sensed by the temperature sensor 8 exceeds the measurement start temperature Tf, the computer 5 reads the temperature sensed by the temperature sensor 8 at regular intervals (for example, one second). Then, when the number of measured values reaches 5, the computer 5 calculates the following Equation 1,
2 is performed to determine whether to avoid the temperature cut mode.

Formula 1 ΔT1 = Tmax−Tmin where ΔT1 indicates the first temperature difference, Tmax indicates the maximum value among the five measured values, and Tmin indicates the minimum value among the five measured values. . Formula 2 ΔT2 = Tn- (Tn-4) where ΔT2 represents the second temperature difference, Tn represents the latest measured value of the fifth piece, and Tn-4 represents the oldest measured value of the first piece.

The determination result of the computer 5 indicates that the first temperature difference ΔT1 = 12 ° C. is the reference temperature difference Δ, as indicated by the solid line in FIG.
If the temperature is higher than Ts (eg 10 ° C.), it is determined that the pan is shaking and the temperature cut mode is avoided, and even if the temperature Tn sensed by the temperature sensor 8 rises to the cut temperature Ts (eg high cut temperature 250 ° C.) or higher, the gas A high cut (automatic fire extinguishing) for closing the valve 4 is not executed.

As a result, even if the combustion flame fluctuates due to the shaking of the pan and the temperature Tn sensed by the temperature sensor 8 rises above the cut temperature Ts, the gas valve 4 is not closed but is kept open to continue combustion. The usability of the table stove 1 with sensor is improved.

The judgment result of the computer 5 indicates that the first temperature difference ΔT 1 = 4 ° C. is the reference temperature difference ΔT as shown by the broken line in FIG. 3B.
If smaller than s (for example, 10 ° C.) and the second temperature difference Δ
If T2 = 4 ° C. is higher than 0 ° C., it is determined that the cooking pot 6 is in normal use and the temperature cut mode is activated, and the temperature Tn sensed by the temperature sensor 8 is equal to the cut temperature Ts (eg, Immediately after the temperature rises above the high cut temperature of 250 ° C., the gas valve 4 is closed and high cut (automatic fire extinguishing) is executed. For this reason, the cooking pot 6 is prevented from overheating and is excellent in safety.

Even when the low-cut mode is selected as the temperature-cut mode to prevent charring of cooked foods, similar control is performed by replacing the low-cut temperature (for example, 130 ° C.) and the measurement start temperature (for example, 80 ° C.). I,
It is possible to shake the pan without automatically extinguishing the fire.

FIG. 5 shows a second embodiment according to claim 1 of the present invention and is a flow chart showing an example of the operation of the computer 5. The same controls as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

If the measurement start temperature Tf is set to a temperature substantially equal to the cut temperature, it is not necessary to determine Tn ≧ Ts in step S11. That is, when the temperature rises above the measurement start temperature Tf (for example, 245 ° C.), the measurement of the temperature sensed by the temperature sensor 8 is started, and the first temperature difference ΔT1 ≧ reference temperature difference ΔT
The execution of temperature cut may be determined only by the determination of s and the second temperature difference ΔT2 ≧ 0 ° C. In this case, the measurement start temperature Tf is the cut temperature (for example, the high cut temperature 250
It is desirable to set the temperature just before (e.g., 245 ° C) which is almost equal to (° C).

6 to 8 are views showing a third embodiment according to claim 2 of the present invention. FIG. 6 is a schematic diagram showing a main part of the table cooker with the temperature sensor. The same reference numerals as in the first embodiment represent the same items.

The control device of this embodiment comprises a computer 5 for controlling the gas valve 4 according to the outputs of the temperature sensor 8 and the setting device 9. This computer 5 has a measuring circuit 2
0, a memory circuit 21, an arithmetic circuit 22, and a determination circuit 23 are built in.

A case where the high cut mode is selected by the setting device 9 will be described. The measuring circuit 20 is the measuring means of the present invention, and senses the temperature sensor 8 at regular intervals (for example, 5 seconds) from the time when the temperature sensed by the temperature sensor 8 rises above the measurement start temperature Tf (for example, 200 ° C.). Temperature Tn
To measure. The storage circuit 21 is the storage means of the present invention, and is the temperature sensor 8 measured by the measurement circuit 20 at regular intervals.
The sensed temperature (hereinafter, referred to as a measured value) Tn of is stored.

The arithmetic circuit 22 obtains the target temperature Tm {= ΔT + (Tn-1)} predicted from the temperature difference ΔT {= (Tn-1)-(Tn-2)} of the two previous measured values. . Judgment circuit 2
3 is that the temperature difference ΔTn between the target temperature Tm and the measured value Tn obtained by the arithmetic circuit 22 is a reference temperature difference ΔTs (for example, ± 1).
(0 ° C) or higher is determined.

Further, as shown by the solid line in FIG. 7C, the computer 5 determines that the temperature difference ΔTn is larger than the reference temperature difference ΔTs when the temperature cut mode is set, that is, | ΔTn | ≧ ΔTs. If the temperature sensor 8
Even if the sensed temperature Tn of the temperature rises above the cut temperature Ts (for example, a high cut temperature of 250 ° C.), the high cut (automatic fire extinguishing) for closing the gas valve 4 is not executed.

On the contrary, when the temperature difference ΔTn is smaller than the reference temperature difference ΔTs, that is, | ΔTn | <ΔTs, the cooking pot 6 is normally placed on the cooking pot 6 as shown by the solid line in D of FIG. The temperature T detected by the temperature sensor 8 is judged as being in use.
n is the cut temperature Ts (for example, high cut temperature 250 ° C.)
Immediately after rising above the above, high cut (automatic fire extinguishing) for closing the gas valve 4 is executed.

Even when the low cut mode is selected as the temperature cut mode, the low cut temperature (for example, 13
The same control is performed with the measurement start temperature (for example, 90 ° C.) replaced.

FIG. 8 is a flow chart showing an example of the operation of the computer 5. First, it is determined whether or not the temperature cut mode is set (step S21).
When the temperature cut mode is not set (No), the control of step S21 is performed.

In step S21, the temperature cut mode is set, and when the temperature sensed by the temperature sensor 8 reaches 250 ° C., for example, the high cut mode is set in which the gas valve 4 is closed to automatically extinguish the fire (Yes). )Time,
Whether the sensed temperature Tn of the temperature sensor 8 has risen above the measurement start temperature Tf (for example, 200 ° C.), that is, T
It is determined whether n ≧ Tf (step S22). Tn ≧
When it is not Tf (No), the control of step S21 is performed.

In step S22, when Tn ≧ Tf (Yes), it is determined whether or not a fixed time (for example, 5 seconds) has elapsed since the previous measurement of the sensed temperature Tn (step S23). The fixed time has not passed (N
At the time of o), the control of step S23 is performed.

In step S23, when the fixed time has elapsed (Yes), the temperature Tn sensed by the temperature sensor 8 is measured and stored (step S24). Next, it is determined whether or not three or more measurement values are stored (step S25). Three or more measured values are not stored (N
At the time of o), the control of step S23 is performed.

In step S25, when three or more measured values are stored (Yes), it is predicted from the temperature difference ΔT {= (Tn-1)-(Tn-2)} between the two previous measured values. Target temperature Tm {= ΔT + (Tn-1)} is obtained (step S26), the temperature difference ΔTn between the target temperature Tm and the latest measured value Tn is obtained (step S27), and the temperature difference ΔTn is the reference temperature difference ΔTs ( For example, whether it is larger than ± 10 ° C),
That is, it is determined whether or not | ΔTn | ≧ ΔTs (step S28). | ΔTn | ≧ ΔTs (Yes)
At this time, it is determined that the pan is shaken, the temperature cut is avoided, and the oldest measurement value (Tn-2) is deleted (step S29). Then return.

In step S28, | ΔTn | ≧ Δ
When it is not Ts (No), it is determined that the cooking pot 6 is normally used and the temperature cut mode is activated. The temperature sensed by the temperature sensor 8 is the cut temperature Ts.
It is determined whether or not the temperature has risen above (for example, 250 ° C.), that is, whether Tn ≧ Ts (step S30).
When Tn ≧ Ts (Yes), the gas valve 4 is closed to automatically extinguish the fire (step S31), and the control ends.

In step S30, when Tn ≧ Ts is not satisfied (No), step S29 is performed.

When the cooking pot 6 is filled with oil or ingredients, the temperature Tn detected by the temperature sensor 8 fluctuates greatly.
The temperature cut may be avoided from the second time except when the temperature difference ΔTn becomes equal to or larger than the reference temperature difference ΔTs at the first time.

In the third embodiment, the third measured value T
After measuring n, the target temperature Tm predicted from the first measured value Tn-2 and the second measured value Tn-1 is calculated, and the temperature difference between the target temperature Tm and the third measured value Tn is calculated. ΔTn was calculated, but after measuring the third measurement value Tn, the target temperature Tm predicted from the first measurement value Tn-2 and the second measurement value Tn-1 is calculated and stored, After returning, 3
Target temperature T stored when the second measured value Tn is measured
The temperature difference ΔTn between m and the third measured value Tn may be calculated.

FIG. 9 is a flow chart showing an example of the operation of the computer 5, showing a fourth embodiment according to claim 2 of the present invention. The same controls as those in the third embodiment are designated by the same reference numerals, and the description thereof will be omitted.

If the measurement start temperature Tf is set to a temperature substantially equal to the cut temperature, it is not necessary to particularly determine Tn ≧ Ts in step S30. That is, the measurement start temperature Tf
When the temperature rises above (for example, 245 ° C.), the measurement of the temperature sensed by the temperature sensor 8 may be started, and the temperature cut may be determined only by determining the temperature difference | ΔTn | ≧ the reference temperature difference ΔTs. In this case, it is desirable that the measurement start temperature Tf be a temperature (for example, 245 ° C.) immediately before the cutting temperature (for example, a high cut temperature of 250 ° C.) that is substantially equal to the cutting temperature.

(Modification) In this embodiment, when the temperature difference between the temperature sensed by the temperature sensor or the temperature difference between the sensed temperature and the target temperature measured at regular intervals is larger than the reference temperature difference,
The temperature cut was avoided without time limitation until the temperature difference became smaller than the reference temperature difference, but a predetermined time (for example, 15 seconds) from the time when the temperature difference became the reference temperature difference or more or the time when the temperature reached the cut temperature. The temperature cut may be avoided only until the time elapses.

Further, in this embodiment, if the cooking pan is placed with the pan swing stopped while it is determined that the pan is shaken and the temperature cut is avoided, the temperature difference is always smaller than the reference temperature difference. It is determined that the temperature cut mode is working again.

A method for determining whether or not the cooking pot is placed again by stopping the swinging of the pot is to compare the temperature difference based on the temperature sensed by the temperature sensor with the reference temperature difference as in this embodiment. In addition to the determination, as shown in FIG. 11, when the cooking pot 6 is placed, it is turned on (or off) by overcoming the elastic force of the spring 31 and pushing down the temperature sensor 8 by the cooking pot 6. The limit switch 32 that operates may be provided separately. According to this method, even if it is not determined that the temperature difference is smaller than the reference temperature difference, it is possible to immediately determine whether or not the cooking pot 6 is placed again.

The temperature cut mode may be a one-step cut only at a predetermined temperature (for example, a high cut temperature of 250 ° C.). Further, in the case of a plurality of steps of temperature cut, if only the highest cut temperature (for example, a high-high cut temperature of 290 ° C.) is determined to be the pan swing in the present invention, the temperature cut is not avoided. It is good because it can prevent overheating. Furthermore, the present invention may be applied to a heating cooker in which the temperature cut mode cannot be set or reset and the temperature cut mode always works.

In this embodiment, the gas burner which burns the fuel gas is used as the heating means, but a burner which burns the liquid fuel may be used. Although a thermistor is used as the temperature sensor in this embodiment, a thermocouple or the like may be used as the temperature sensor.
