The present invention relates to a cooking heater safety control method and a cooking heater safety control device.

First, a cooking heating apparatus safety control method according to an embodiment of the present application (hereinafter referred to as a 'first cooking heating apparatus safety control method') will be described.

1 is a flowchart illustrating a method for safely controlling a cooking appliance according to an embodiment of the present application, and FIG. 2 is a function in which the cooking appliance is turned off when the weight loss ratio maintains a peak value for a predetermined time or more. FIG. 3 is a flowchart illustrating a case where the signal is turned off, and FIG. 3 is a flowchart illustrating a case in which a function of turning off the cooking heating mechanism is turned on when the weight loss ratio maintains a peak value for a predetermined time or more.

The first cooking appliance safety control method is a method for automatically turning off the cooking appliance which is heated to the heating object.

In exemplary embodiments, the cooking heating apparatus may be an electric range such as a hot plate, an induction range, a gas range, or the like.

Referring to FIG. 1, the first cooking heating apparatus safety control method includes calculating a weight reduction rate by measuring a weight of a heating object over time (S100).

The object to be heated may mean a container to be heated and an object contained in the container. In general, considering that a cooking heating apparatus is used for cooking, the container may be a cooking container, and the object may be food.

In general, while the heating of the heating object is in progress, the weight of the heating object is reduced by evaporation of water or the like contained in the heating object with water vapor.

Step S100, more specifically, may be as follows.

Step S100 may include measuring the weight of the heating object before and after the time interval at a time interval.

The weight of the heating object can be measured continuously while the heating object is heated at a time interval. For example, when the time interval is 1 minute, the weight of the heating object may be repeatedly measured every minute.

In addition, the step of measuring the weight may be started as soon as, for example, the heating for the heating object is started.

In addition, step S100 may include calculating a weight reduction rate per time interval according to the difference in the weight of the heating object before and after the time interval.

For example, if the time interval is 1 minute, the weight of the heating object measured one minute before the weight is 800g, the weight of the heating object measured after one minute is 780g, the weight reduction rate is 20g per time interval (1 min) Can be. As another example, when the time interval is 5 minutes, the weight of the heating object measured 5 minutes ago is 800g, and the weight of the heating object measured after 5 minutes is 710g, the weight reduction rate is 90g per 5 minutes time interval. have.

In addition, the weight reduction rate can be continuously calculated while the weight of the heating object is measured. For example, the n th weight reduction rate may be calculated by the difference between the (n-1) th weight and the n th weight.

In addition, the step of calculating the weight loss rate can begin immediately after the second weight is measured. In this case, the first estimated weight loss rate can be estimated by the difference between the first measured weight and the second measured weight.

In addition, in general, it is preferable that the time interval is set in minutes in consideration of the fact that heating for food is performed within a range of one hour. In exemplary embodiments, the time interval may be 1 minute.

In addition, referring to FIG. 1, the first cooking heating apparatus safety control method includes turning off the cooking heating apparatus when the weight reduction rate rises to a peak value and is switched downward as the heating progress of the heating object is performed ( S300) may be included.

In general, the food is heated in the cooking vessel is boiled water (soup, moisture of the dry, etc.) contained in the food boils and evaporates into water vapor, the weight loss rate is gradually increased when water vapor begins to occur in the food. In addition, when the water of the food foams and boils, the weight loss rate has a peak value, and the peak value of the weight loss rate is maintained until the surface area of the food water decreases. When the surface area of food water decreases, the weight loss rate also decreases.

As another example, even if the food contains water in the inside, such as fish, the weight loss rate has a peak value when the rate of evaporation of water in the inside is the fastest. In addition, the weight reduction rate having a peak value and then down-converted may mean that the fish meat is gradually solidifying due to evaporation of water in the fish for a predetermined time or more.

Therefore, even if the food has any form such as fish or raw meat in addition to the broth dish, the time when the cooking is completed and the heating is to be completed may be set based on the time when the weight reduction rate reaches a peak after the weight reduction rate reaches the peak. have. In addition, as will be described later, when the weight reduction rate rises to the peak value and is down-converted, the cooking heating mechanism is turned off when the weight reduction rate becomes less than or equal to the preset value in comparison with the peak value, thereby adjusting the preset ratio. Detailed settings may be made.

The first cooking heating apparatus safety control method may turn off the cooking heating apparatus when the weight reduction ratio rises to a peak value and is switched downward in response to the change in the weight reduction ratio.

In addition, the cooking apparatus may be turned off by cutting off the fuel supply. For example, when the cooking heating apparatus is a gas range, the gas supply may be stopped. In addition, when the cooking heating apparatus is an electric range, the electricity supply may be cut off.

In addition, in step S300 of turning off the cooking apparatus, as shown in FIG. 1, when the weight reduction rate rises to a peak value and is down-converted, when the weight reduction rate is less than or equal to a preset ratio, the cooking is performed. The heating device may be turned off.

The first cooking heating apparatus safety control method may be implemented such that a user using the cooking heating apparatus may change the preset ratio to another ratio. In exemplary embodiments, the preset ratio may be 50%.

In addition, the step of turning off the cooking heating mechanism, may be conditionally set so that the cooking heating mechanism is turned off when the weight reduction rate maintains the peak value for a predetermined time or more.

Here, the conditional setting is possible when the user using the first cooking heating apparatus safety control method wants to use the function of turning off the cooking heating apparatus when the weight reduction ratio maintains the peak value for a predetermined time or more. This means that this feature can be turned on and used, and if it is not desired, it can be selectively set as needed so that it can be turned off and not used.

When the weight reduction rate maintains a peak value for a predetermined time or more, when the function of turning off the cooking heating mechanism is OFF, as shown in FIG. 2, the first cooking heating apparatus safety control method may include a weight reduction rate. When the temperature rises up to the peak value and is down-converted, the cooking heating apparatus may be turned off when the ratio is less than or equal to the preset value.

In addition, when the function of turning off the cooking heating mechanism is turned on when the weight loss ratio maintains the peak value for a predetermined time or more, as shown in FIG. 3, the first cooking heating apparatus safety control method may include: When the reduction ratio maintains the peak value for a predetermined time or more, the cooking heating apparatus may be turned off. Referring to FIG. 3, even when the weight loss rate does not maintain the peak value for a predetermined time or more, when the weight decrease rate falls below the set ratio in comparison with the peak value, the cooking heating apparatus may be turned off. That is, the double safety control can be achieved through this.

Considering that most of the food is not boiled for more than 10 minutes, the preset time may be, for example, 10 minutes.

In addition, the first cooking heating apparatus safety control method may be implemented so that the user can change the predetermined time to a different time value. For example, when boiling a food that must be maintained for a long time, such as Gomtang, the user may set the preset time longer than the above 10 minutes, for example, about 2 to 4 hours.

On the other hand, in the first cooking heating mechanism safety control method, in the step of turning off the cooking heating mechanism, the warning sound may be sounded before the cooking heating mechanism is turned off.

The time when the cooking heating apparatus is turned off is the point at which the weight reduction rate becomes less than or equal to the preset value relative to the peak value.In order to sound an alarm before the cooking heating apparatus is turned off, the weight reduction ratio is set in advance as compared to the peak value. The following point should be predicted in advance within a predetermined tolerance.

Hereinafter, assuming that the warning sound is set to sound for 30 seconds, an example of a process of sounding the alarm sound will be described.

When the weight reduction rate rises to the peak value and then is turned down and falls below the preset ratio in comparison with the peak value, when the cooking heater is turned off, the preset ratio is 50% (1/2) and the time interval is 1 In the case of minutes, if the weight loss rate calculated by the (n-1) th weight is 56% of the peak value and the weight loss rate calculated by the nth measured weight is 53% of the peak value, this leading trend is obtained. It can be estimated that the (n + 1) th weight reduction rate is 50% or less of the peak value. Accordingly, the warning sound can be made 30 seconds after the nth weight is measured, that is, 30 seconds before the (n + 1) th weight is measured.

Hereinafter, a cooking heater safety control device (hereinafter, referred to as a 'first cooking heating device safety control device') will be described. However, the same reference numerals are used for the same or similar components as the above-described salping configuration, and redundant descriptions will be briefly or omitted.

4 is a conceptual view illustrating a safety control device for a cooking heating apparatus according to an embodiment of the present application.

The first cooking appliance safety control device is a device for automatically turning off the cooking appliance which is heated to the heating object.

In exemplary embodiments, the cooking heating apparatus may be an electric range such as a hot plate, an induction range, a gas range, or the like. For reference, FIG. 4 shows a gas range as a cooking heating mechanism.

Referring to FIG. 4, the first cooking heating apparatus safety control device includes a weight measuring unit 1 that measures a weight of a heating object over time.

The weight measuring unit 1 may measure the weight of the heating object before and after the time interval at a time interval.

As shown in FIG. 4, when the cooking heating mechanism is a gas range, for example, the weight measuring unit 1 may be disposed below the pedestal 9. Thereby, the weight of the heating object placed on the pedestal 9 can be measured.

In addition, a timer may be included in the controller 3 to be described later. In this case, the control unit 3 sends a signal to the weight measuring unit 1 at a time interval, and the weight measuring unit 1 measures the weight each time a signal is received, so that the weight measurement can be performed at a time interval. have.

For example, the weight measurement unit may be implemented as follows.

For example, when the cooking heating apparatus is a gas range, four or three holes are formed below the pedestal 9, and a weight sensor connected to the scale may be mounted. In addition, when the heating device for cooking is an electric range, the heating plate and the scale may be directly connected. For example, the electronic scale may be installed in the heating plate. In addition, the electronic balance may be, for example, a balance that can be measured in units of 1 g.

In addition, the weight measuring unit 1 may itself include a timer. In this case, the weight measuring unit 1 may measure the weight of the heating object at intervals of its own time.

In addition, referring to FIG. 4, the first cooking heater safety control device includes a controller 3 that calculates a weight loss rate based on the weight according to the measured time.

The controller 3 may calculate the weight reduction rate per time interval according to the difference in the weight of the heating object before and after the time interval.

In addition, the control unit 3 turns off the cooking heater when the weight reduction rate rises to the peak value and is switched downward.

For example, referring to FIG. 4, the control unit 3 may turn off the cooking heating mechanism by cutting off the fuel supply. The fuel supply may vary depending on the type of cooking apparatus, and in the case of the gas range, the gas supply may be cut off, and in the case of the electric range, the electric supply may be cut off.

In this case, the first cooking heater safety control device may include a fuel supply cutoff switch 5 for shutting off fuel supply to the cooking heater when the controller 3 transmits an off signal. Accordingly, when the cooking heating mechanism is turned off, the cooking heating mechanism can be turned off by operating the fuel supply cutoff switch 5 to cut off the fuel supplied to the cooking heating mechanism. The fuel supply cutoff switch 5 may be a separate configuration from the fuel supply switch of the cooking heating mechanism.

In addition, when the cooking heating mechanism is a gas range, the fuel supply cutoff switch 5 may be a gas supply cutoff switch. In addition, when the cooking heating mechanism is an electric range, the fuel supply cutoff switch 5 may be a power supply cutoff switch. Alternatively, the controller 3 may block the fuel supply by controlling the fuel supply switch of the cooking heating mechanism.

For example, the controller 3 may turn off the cooking apparatus when the weight reduction rate rises to a peak value and then is down-converted and then the weight reduction rate becomes less than or equal to a preset ratio in comparison with the peak value.

In addition, the controller 3 may turn off the cooking heater when the weight reduction rate per time interval maintains the peak value for more than a predetermined time.

In addition, the first cooking heater safety control device may include an alarm (7).

The alarm 7 can output a warning sound immediately before the cooking heating mechanism is turned off.

The alarm sound output time, the alarm sound output duration, etc. of the alarm 7 can be made under the control of the controller 3. Alternatively, the alarm 7 may set the alarm sound output time, the alarm sound duration, and the like.

The first cooking heating apparatus safety control device may be directly applied to the product by the cooking heating apparatus manufacturer, but may be configured as a separate device and mounted on the existing cooking heating apparatus.

In addition, the first cooking appliance safety control device may include an adjustment plate. Such an adjusting plate may be an adjusting plate that is pre-installed in the cooking appliance. However, as described below, when the first cooking heating mechanism safety control device is additionally mounted on the cooking heating mechanism, the adjustment plate may be provided separately from the cooking heating mechanism.

As described above, when the first cooking heater safety control device includes the adjustment plate, the above-described control unit 3 may be embedded in the adjustment plate. In addition, the throttle plate may be connected with a timer, an alarm 7 and a fuel supply cutoff switch 5.

On the other hand, the cooking heating apparatus according to an embodiment of the present application may include a cooking heating apparatus safety control device according to an embodiment of the present application described above.

More specifically, the cooking heating device according to an embodiment of the present application may be implemented as a product in which the first cooking heating device safety control device is built in itself, and the first cooking heating device safety control device is additionally mounted separately. It may be implemented as a product of the form.

The cooking heating apparatus according to an embodiment of the present application may be a gas range, an electric range, or the like as described above, but is not limited thereto, and various cooking heating apparatuses may be applied. In addition, since the detailed configuration of such a cooking heating apparatus corresponds to the configurations that will be apparent to those skilled in the art of cooking heating apparatus, a detailed description thereof will be omitted.

In addition, the computer-readable medium according to an embodiment of the present application may include a program command for performing the above-described first cooking heating apparatus safety control method.

That is, embodiments of the present disclosure may include a computer readable medium including program instructions for performing various computer-implemented operations. The medium records a program or process for executing the first cooking heater safety control method as described so far. The media may include, alone or in combination with the program instructions, data files, data structures, and the like. Examples of such media include, but are not limited to, magnetic media such as hard disks, floppy disks and magnetic tape, optical recording media such as CDs and DVDs, floppy and magnetic-optical media, program instructions such as ROM, RAM and flash memory. Hardware devices configured to store and perform such operations. Alternatively, the medium may be a transmission medium such as an optical or metal wire, a waveguide, or the like including a carrier wave for transmitting a signal specifying a program command, a data structure, and the like. Examples of program instructions may include high-level language code that can be executed by a computer using an interpreter as well as machine code such as produced by a compiler.

On the other hand, it will be described below the cooking heating appliance safety control device (hereinafter referred to as "second cooking heater safety control device") according to another embodiment of the present application. However, the same reference numerals are used for the same or similar components as the above-described salping configuration, and redundant descriptions will be briefly or omitted.

The second cooking heating mechanism safety control device further expands the function of the first cooking heating mechanism safety control device to cook not only when the heating object is heated but also when the heating object is not heated. It relates to a cooking heater safety control device that can automatically turn off the heating device for.

5 is a conceptual view illustrating a safety control device for a cooking heater according to another embodiment of the present application.

The second cooking heating apparatus safety control device includes a weight sensor unit (1) for measuring or calculating the weight reduction rate of the support weight with respect to at least a part of the pedestal (9) capable of supporting a heating object in the cooking heating apparatus over time. Contains').

Referring to FIG. 5, the weight sensor unit 1 ′ is similar to the weight measuring unit 1 described above. However, the weight measuring unit 1 is configured to measure the weight according to the time of the heating object, while the weight sensor unit 1 ′ is installed to support at least a part of the pedestal 9 supporting the heating object, thereby supporting it. It is a configuration that is installed to measure or calculate the weight loss rate for one part.

The weight sensor unit 1 'may be implemented in a manner of calculating the weight loss rate by continuously measuring the weight of the support portion, or may be implemented by measuring the weight reduction rate itself for the support portion. will be.

That is, the weight sensor unit 1 ′ may measure or calculate the weight reduction rate of the pedestal 9 and the entire heating object seated thereon, but for example, as shown in FIG. 6, one side of the pedestal 9 (FIG. As seen from 6, the weight reduction rate of the weight distributed to only one side of the pedestal 9 and a part of pressing the one side of the pedestal of the total weight of the heating object may be measured or calculated.

In other words, in order to measure or calculate the weight loss rate of the weight sensor unit 1 'and the entire heating object seated thereon, the weight sensor unit (for each part of the pedestal 9, which is generally distributed in a plurality), 1 ') and add the measured value or the calculated value, or as shown in the figure, the pedestal 9 is integrally manufactured and the weight sensor part 1' must be accurately placed at the point of the center of gravity. There may be difficulties.

By the way, in the case of the present application, it is not the exact weight of the object to be heated, but the relative variability over time of the weight reduction rate. That is, the present invention cannot be implemented only when the exact value of the weight loss rate is calculated, and when the lifting status (variability) is understood, such as whether the weight loss rate has reached a peak or is maintained at 0, Safety control of the heating mechanism can be fully implemented.

In other words, the weight sensor unit 1 'is not disposed at the portion capable of measuring the weight reduction rate with respect to the total weight of the heating object, and the weight sensor unit is located at the portion capable of measuring the weight reduction rate for the partial weight of the heating object. Even if (1 ') is arranged, it is possible to determine whether the weight loss rate with time has risen to the peak and then turned down, whether it is maintained at a peak for a certain time, or if it is kept at zero without a decrease.

Accordingly, the weight sensor unit 1 ′ measures or calculates the weight reduction rate of the support weight for the entire pedestal 9 that can support the heating object or the weight reduction rate of the support weight for the portion of the pedestal 9 over time. . Since the weight sensor unit 1 'may be implemented through various known weight sensors, a detailed description thereof will be omitted. For example, the weight sensor unit 1 ′ may be implemented in a manner or structure similar to the weight measuring unit 1 described above.

In addition, the second cooking heating apparatus safety control device includes a control unit 3 for turning off the cooking heating apparatus when the variation in the weight reduction rate satisfies a preset off condition.

Here, the preset off condition may include a first condition in which the weight reduction rate rises to a peak value and is converted downward as the heating progresses on the heating object. In addition, the preset off condition may include a second condition in which the weight reduction rate maintains a peak value for a predetermined peak time or more as the heating progresses on the heating object. The preset off condition may include a third condition in which the weight loss rate is maintained at zero or more for a preset waiting time.

That is, the preset off condition may include one or more of a first condition, a second condition, and a third condition.

In addition, when the first condition is satisfied, the control unit 3 may turn off the cooking heating apparatus when the weight loss rate rises to the peak value and is switched downward, and then becomes lower than or equal to the preset ratio in comparison to the peak value. .

In addition, the controller 3 may be implemented such that a user using the cooking heating apparatus can change the preset ratio to another ratio. In exemplary embodiments, the preset ratio may be 50%.

In addition, the controller 3 may be provided to enable conditional setting of the second condition. Here, the conditional setting is possible, as described above, if the user wants to use the cooking heating apparatus off function according to the second condition, the function can be turned on (ON), and if it is not desired, the function is turned off ( OFF) means that it can be set (conditionally) as needed so that it is not used. In addition, if necessary, the controller 3 may be provided to enable conditional setting as described above for the first condition and the second condition.

The first condition and the second condition are described in the same or similar manner in the above-described embodiment of the present application, so detailed description thereof will be omitted.

In addition, when the third condition is satisfied, the control unit 3 may shut off the supply of fuel (heating source) to the cooking heating mechanism and turn off the cooking heating mechanism. The third condition is a condition set to allow the cooking heater to be automatically turned off by a method such as blocking the supply of fuel such as gas by easily grasping it even when the cooking heater is not used for a predetermined time or more.

That is, when the weight reduction rate corresponds to the third condition that is maintained at 0 or more for a predetermined time, since the weight of the heating object is not fluctuated for a predetermined time or more, it may be understood that the cooking heater is not used for a predetermined time or longer. . Accordingly, when the third condition is satisfied, the cooking heating mechanism is automatically turned off by a method such as shutting off the supply of fuel such as gas, so that the second cooking heating mechanism safety control device is configured to supply the same fuel as the gas supply blocking device. It can cover the role of supply cutoff device.

The control unit 3 can turn off the cooking heating mechanism by cutting off the fuel supply not only in the case of the above-mentioned third condition but also in the case of the first or second condition. The fuel supply may vary depending on the type of cooking apparatus, and in the case of the gas range, the gas supply may be cut off, and in the case of the electric range, the electric supply may be cut off.

In this case, the second cooking heater safety control device may include a fuel supply cut-off switch 5 to cut off fuel supply to the cooking heater when the controller 3 transmits an off signal. Accordingly, when the cooking heating mechanism is turned off, the cooking heating mechanism can be turned off by operating the fuel supply cutoff switch 5 to cut off the fuel supplied to the cooking heating mechanism. The fuel supply cutoff switch 5 may be a separate configuration from the fuel supply switch of the cooking heating mechanism.

In addition, when the cooking heating mechanism is a gas range, the fuel supply cutoff switch 5 may be a gas supply cutoff switch. In addition, when the cooking heating mechanism is an electric range, the fuel supply cutoff switch 5 may be a power supply cutoff switch. Alternatively, the control unit 3 may be implemented to block the fuel supply by directly controlling the fuel supply switch of the cooking heating mechanism.

In addition, the above-described preset peak time and preset standby time may be set by the user. In addition, the peak time and the standby time may have a default setting value even if not set by the user. For example, the default setting may have a value between 10 and 30 minutes.

In addition, the controller 3 may include a setting unit for setting such a peak time, a waiting time, and the like.

In addition, the second cooking heater safety control device may include an alarm (7).

The alarm 7 can output a warning sound immediately before the cooking heating mechanism is turned off.

In addition, the alarm 7 may be set not to sound a warning sound for a specific condition among the first to third conditions. For example, the alarm 7 may be set to sound an alarm for the first condition and the second condition, and may be set so that the alarm does not sound for the third condition associated with the non-use of the cooking appliance for a certain time.

The alarm sound output time, the alarm sound output duration, etc. of the alarm 7 can be made under the control of the controller 3. Alternatively, the alarm 7 may set the alarm sound output time, the alarm sound duration, and the like.

In addition, the second cooking heating apparatus safety control device may be directly applied to the product from the cooking appliance manufacturer, it may be configured as a separate device mounted on the existing cooking heating apparatus applied.

The first cooking heater safety control device may include an adjusting plate. Such an adjusting plate may be an adjusting plate that is pre-installed in the cooking appliance. However, as described below, when the second cooking heating mechanism safety control device is additionally mounted on the cooking heating mechanism, such an adjusting plate may be provided separately from the cooking heating mechanism.

As such, when the second cooking heating apparatus safety control device includes the adjustment plate, the above-described control unit 3 may be embedded in the adjustment plate. And, the setting unit described above may be provided in the adjustment plate. In addition, the throttle plate may be connected with a timer, an alarm 7 and a fuel supply cutoff switch 5.

On the other hand, it will be described below for the cooking heating appliance safety control method according to another embodiment of the present application (hereinafter referred to as "second cooking heating appliance safety control method"). However, duplicate descriptions of the same or similar components as the above-described salping configuration will be briefly or omitted.

The second cooking heating apparatus safety control method further expands the function of the first cooking heating apparatus safety control method to cook not only when the heating object is heated but also when the heating object is not heated. The present invention relates to a cooking heating apparatus safety control method capable of automatically turning off the heating apparatus.
