When the knob is positioned at a preset third point, the controller may open the modulating valve and close the boosting valve.

When the knob is positioned at a preset third point, the controller may close the boosting valve and intermittently open the modulating valve.

When the knob deviates from the first point and the second point, the controller may close the boosting valve and control an opening time of the modulating valve according to the position of the knob.

When the knob returns to the first point again in a state of deviating from the first point, the controller may determine whether a preset ignition time has elapsed after the ignition device is operated, and may determine whether to re-operate the ignition device based on whether the preset ignition time has elapsed.

When the knob returns to the second point again in a state of deviating from the second point, the controller may determine whether a preset boosting delay time has elapsed after the boosting mode is operated, and may determine whether to re-operate the boosting mode based on whether the preset boosting delay time has elapsed.

<FIG> schematically illustrates a configuration of a range assembly illustrated in <FIG>.

Hereinafter, the configuration of the range assembly <NUM> will be described with reference to <FIG>. Although the plurality of range assemblies <NUM> may be provided as described above, for convenience of description, only one of the range assembly <NUM> will be described as an example.

Referring to <FIG>, the range assembly <NUM> includes a gas valve <NUM> to receive gas from the outside. The gas valve <NUM> guides gas supplied from an external gas supply source (not shown) to the gas passage <NUM>. The gas valve <NUM> may open and close a flow passage through which gas supplied from the external gas supply source moves to the gas passage <NUM>. The gas valve <NUM> adjusts the degree of opening of a gas supply passage as the knob <NUM> rotates. For example, when the knob <NUM> is rotated by <NUM> degrees, the gas valve <NUM> may open the gas supply passage to a maximum size, and when the knob <NUM> is further rotated up to <NUM> degrees, the gas valve <NUM> may reduce the size of the gas supply passage to open the gas supply passage to the minimum size. The gas valve <NUM> may be one of a manual valve, a solenoid valve, and a modulating valve.

The range assembly <NUM> includes a modulating valve <NUM> to open and close the gas passage <NUM>. The modulating valve <NUM> is disposed on the gas passage <NUM>. The modulating valve <NUM> is connected to a controller <NUM> to be controlled by the controller <NUM>. The modulating valve <NUM> may be a solenoid valve.

The range assembly <NUM> includes a boosting valve <NUM> disposed on a boosting passage <NUM> branched from the gas passage <NUM>. The boosting valve <NUM> is provided to open and close the boosting passage <NUM>. The boosting valve <NUM> is connected to the controller <NUM> to be controlled by the controller <NUM>. The boosting valve <NUM> may be a solenoid valve.

The modulating valve <NUM> and the boosting valve <NUM> may be disposed in parallel on a single frame <NUM>. Although not shown, the modulating valve <NUM> and the boosting valve <NUM> may be disposed in series on a single frame. Also, the modulating valve <NUM> and the boosting valve <NUM> are not disposed on a single frame and may be disposed separately.

The range assembly <NUM> includes a first nozzle <NUM>. The first nozzle <NUM> may limit an amount by which gas passed through the modulating valve <NUM> is supplied to a heating device <NUM> when the range assembly <NUM> is operated in a normal mode. Specifically, the first nozzle <NUM> may limit the amount of gas supplied to the heating device <NUM> when the range assembly <NUM> is operated in the normal mode. The first nozzle <NUM> is disposed at the rear of the modulating valve <NUM> (that is, to the right of the modulating valve <NUM> in <FIG>) along a direction in which gas in the gas passage <NUM> flows (that is, from left to right in <FIG>).

The range assembly <NUM> includes a second nozzle <NUM>. The second nozzle <NUM> may limit an amount by which gas passed through the boosting valve <NUM> is supplied to the heating device <NUM> when the range assembly <NUM> is operated in a boosting mode. Specifically, the second nozzle <NUM> may limit the amount by which gas passed through the boosting valve <NUM> and the first nozzle <NUM> is supplied to the heating device <NUM>.

The heating device <NUM> is configured to apply heat to a cooking container as gas is supplied through the gas passage <NUM> and is ignited by an ignition device <NUM>.

The range assembly <NUM> includes a sensor <NUM>. The sensor <NUM> may be mounted on a shaft 111a of the gas valve <NUM>. The sensor <NUM> may be disposed adjacent to the gas valve <NUM>. The sensor <NUM> may detect a rotation position of the knob <NUM> and transmit information on the rotation position of the knob <NUM> to the controller <NUM>.

For example, when the knob <NUM> is positioned at a boosting mode point, the sensor <NUM> may detect and transmit this position to the controller <NUM>, and the controller <NUM> may open the boosting valve <NUM> so that the range assembly <NUM> may be operated in the boosting mode. At this time, the controller <NUM> may also open the modulating valve <NUM>.

On the other hand, the sensor <NUM> may be configured not to transmit separate information to the controller <NUM> when the knob <NUM> deviates from the boosting mode point. Accordingly, the controller <NUM> may close the boosting valve <NUM> so that the range assembly <NUM> operates in the normal mode. In this case, the controller <NUM> may open the modulating valve <NUM>. With the above configuration, the range assembly <NUM> according to an embodiment of the present disclosure may easily operate the boosting mode with a relatively simple configuration by the sensor <NUM>.

The ignition device <NUM> is provided such that the heating device <NUM> is ignited when gas is supplied to the heating device <NUM>. The ignition device <NUM> is connected to the controller <NUM> to be controlled by the controller <NUM>.

The gas passage <NUM> is configured to guide gas supplied through the gas valve <NUM> to the heating device <NUM>. The modulating valve <NUM> and the first nozzle <NUM> may be disposed on the gas passage <NUM>. The second nozzle <NUM> may be disposed at one end of the gas passage <NUM> close to the heating device <NUM>.

The boosting passage <NUM> is provided to be branched and extend from one portion of the gas passage <NUM> and to be joined to the other portion of the gas passage <NUM>. In this case, the one portion of the gas passage <NUM> to which the boosting passage <NUM> is branched is disposed in front of the other portion of the gas passage <NUM> where the boosting passage <NUM> is joined to the gas passage <NUM>, based on a direction in which the gas flows (that is, on the left based on <FIG>). The boosting valve <NUM> is disposed on the boosting passage <NUM>.

The controller <NUM> controls the operation of the range assembly <NUM>. The controller <NUM> may receive position information of the knob <NUM> from the sensor <NUM>. The controller <NUM> is connected to the modulating valve <NUM> to control the opening and closing operation of the modulating valve <NUM>. The controller <NUM> is connected to the boosting valve <NUM> to control the opening and closing operation of the boosting valve <NUM>. The controller <NUM> is connected to the ignition device <NUM> to control the ignition device <NUM> to ignite the heating device <NUM> when the knob is positioned at an ignition point. The controller <NUM> may be connected to a notification device <NUM> to turn on the notification device <NUM> when the range assembly <NUM> is operated in the boosting mode.

The controller <NUM> may be implemented as a memory (not shown) for storing an algorithm for controlling the operation of components in the range assembly <NUM> or a data for a program reproducing the algorithm and a processor (not shown) for performing the above-described operations using data stored in the memory. In this case, the memory may be implemented as a separate chip from the processor, and may be implemented as a single chip with the processor.

The range assembly <NUM> may include the notification device <NUM> to allow a user to recognize the boosting mode by being lit when the knob <NUM> is positioned at the boosting mode point.

Although not shown, the range assembly <NUM> may further include an ignition detection means capable of detecting whether the heating device <NUM> is ignited, and the ignition detection means may include an ignition sensor or an ignition detection electrode. The detection result may be provided to the controller <NUM>.

Some components illustrated in <FIG> may be software and/or hardware components such as Field Programmable Gate Array (FPGA) and Application Specific Integrated Circuit (ASIC).

Hereinafter, a process in which the controller <NUM> controls each component of the range assembly <NUM> will be described in detail with reference to <FIG>.

<FIG> illustrates for explaining a temperature of a cooking container that changes by the operation of the range assembly described above and a method of operating each valve of the range assembly.

The controller <NUM> closes the modulating valve <NUM> and the boosting valve <NUM> so that gas is not supplied to the heating device <NUM> when the knob is positioned at a first point (initial point, for example, the point of <NUM> degrees).

When the user positions the knob at a second point (ignition point, for example, the point of <NUM> degrees), the controller <NUM> opens the modulating valve <NUM> and turns on the ignition device <NUM> to ignite the heating device <NUM>.

Referring to Ta in FIG. 4A, when a temperature of a cooking container reaches a certain level, the conventional cooking apparatus <NUM> reduces the rate of increase in the temperature of the cooking container at a time point tNMa to prevent fire, and in the case of the conventional cooking apparatus <NUM>, gas supplied to the ignition device <NUM> may be controlled only by only one valve, so that it takes a long time (tNMa) to increase the temperature of gas to the certain level.

However, referring to Tb in FIG. 4A, in the case of the cooking apparatus <NUM> according to an embodiment, the boosting valve <NUM> and the modulating valve <NUM> are provided in the cooking apparatus <NUM>, so that it takes a time (tNMb) shorter than before to increase the temperature of gas to the certain level.

Specifically, the controller <NUM> of the cooking apparatus <NUM> according to an embodiment operates the boosting mode when the knob is positioned at a third point (boosting point, for example, the point of <NUM> degrees), and opens both the boosting valve <NUM> and the modulating valve <NUM> in the boosting mode.

When the boosting valve <NUM> is opened in the boosting mode, the gas supply is not limited by the first nozzle <NUM> in the boosting passage <NUM>, so that a large amount of gas may be quickly supplied to the heating device <NUM>.

The controller <NUM> terminates the boosting mode and operates the normal mode when a preset boosting time elapses or the knob position deviates from the third point (for example, when the knob position is over <NUM> degrees and less than <NUM> degrees). The controller <NUM> opens the modulating valve <NUM> and closes the boosting valve <NUM> in the normal mode. The normal mode may include a normal max mode of continuously closing the boosting valve <NUM> and continuously opening the modulating valve <NUM> when the boosting time elapses, and a normal simmer mode of continuously closing the boosting valve <NUM> and intermittently opening and closing the modulating valve <NUM> when the knob position deviates from the third point.

As illustrated in FIG. 4B, in the boosting mode, the controller <NUM> may not only continuously open the boosting valve <NUM>, but also intermittently repeatedly control the opening and closing of the boosting valve <NUM>. Also, the controller may continuously open the modulating valve <NUM> in the boosting mode.

When a preset boosting time tN elapses, the controller <NUM> may operate the normal max mode, close the boosting valve <NUM>, and continuously open the modulating valve <NUM>.

As such, the supply rate of gas supplied to the heating device <NUM> may be adjusted by the intermittent control of the boosting valve <NUM> in the boosting mode, and thus the rate of temperature increase of the cooking container may also be adjusted.

As illustrated in FIG. 4C, when the knob is deviated from the boosting mode point at a time point tNMb according to the user's manipulation, the controller <NUM> may operate the normal simmer mode.

In the normal simmer mode, the controller <NUM> may not only continuously open the modulating valve <NUM>, but also intermittently repeatedly control the opening and closing of the modulating valve <NUM>. However, as in normal max mode, the controller continuously closes the boosting valve <NUM> in the normal simmer mode.

In the normal simmer mode, the controller <NUM> may adjust the opening duration and the closing duration of the modulating valve <NUM> according to the position of the knob. For example, the controller <NUM> may repeatedly perform the operation of opening the modulating valve <NUM> for <NUM> seconds and closing for <NUM> seconds when the knob is positioned at a fourth point (for example, at the point of <NUM> degrees), and may repeatedly perform the operation of opening the modulating valve <NUM> for <NUM> seconds and closing for <NUM> seconds when the knob is positioned at a fifth point (for example, at the point of <NUM> degrees).

In the normal simmer mode, the controller <NUM> may gradually increase the opening duration of the modulating valve <NUM> when the knob is positioned at a preset automatic adjustment point (for example, more than the point of <NUM> degrees and less than the point of <NUM> degrees).

For example, when the knob is positioned at the automatic adjustment point, the controller <NUM> may perform the operations of opening the modulating valve <NUM> for <NUM> seconds and closing for <NUM> seconds and then opening for <NUM> seconds and closing for <NUM> seconds, and then opening for <NUM> seconds and closing for <NUM> seconds, and then opening for <NUM> seconds and closing for <NUM> seconds, and then repeatedly opening for <NUM> seconds and closing for <NUM> seconds.

Even when the knob is positioned at a point for supplying the maximum amount of gas, the amount of gas supplied to the heating device <NUM> gradually increases, so that an accident due to a sudden increase in the amount of gas may be prevented.

When the user positions the knob back to the first point, both the modulating valve <NUM> and the boosting valve <NUM> are closed, so that gas is not supplied to the heating device <NUM>.

However, when the user attempts to operate the boosting mode again in the normal simmer mode, the knob may return to the third point from a point deviating from the third point, and the controller <NUM> may operate the boosting mode again.

On the other hand, the controller <NUM> of the cooking apparatus <NUM> according to another embodiment determines whether a preset boosting delay time (for example, <NUM> minutes) has elapsed after the boosting mode is operated in order to reduce a risk due to excessive continuation of the boosting mode, and may operate the boosting mode again only when the boosting delay time elapses and the knob is positioned at the second position.

When the user attempts to ignite the heating device <NUM> again, the knob may return to the first point from a point deviating from the first point, and the controller <NUM> may operate the ignition device <NUM> again.

The controller <NUM> of the cooking apparatus <NUM> according to another embodiment determines whether a preset ignition time (for example, <NUM> minute) has elapsed after the ignition device <NUM> is operated in order to reduce a risk due to excessive operation of the ignition device <NUM>, and may operate the ignition device <NUM> again only when the knob is positioned at the first point after the ignition time elapses.

Hereinafter, a method of controlling the cooking apparatus <NUM> according to an embodiment will be described with reference to <FIG> is a flowchart of a method of controlling the cooking apparatus according to an embodiment of the present disclosure.

Hereinafter, for convenience of explanation, it will be described for example that the first point is a point where a rotation angle of the knob that is physically rotated is <NUM> degrees, the second point is a point where the rotation angle of the knob is <NUM> degrees, the third point is a point where the rotation angle of the knob is <NUM> degrees, the fourth and fifth points are points where the rotation angle of the knob exceeds <NUM> degrees and is <NUM> degrees or less, respectively, and a sixth point is a point where the rotation angle of the knob exceeds <NUM> degrees, but each point may be positioned at a different point.

First, the cooking apparatus <NUM> according to an embodiment closes both the modulating valve <NUM> and the boosting valve <NUM> when the knob is positioned at <NUM> degrees ("YES" in <NUM>) (<NUM>). Thereafter, when the knob is positioned at the point of <NUM> degrees ("YES" in <NUM>), the cooking apparatus <NUM> opens the modulating valve <NUM> and closes the boosting valve <NUM> to ignite the heating device <NUM> by operating the ignition device <NUM> while suppling gas to the heating device <NUM> (<NUM>).

Then, when the knob is positioned at the <NUM> degree point ("YES" in <NUM>), the cooking apparatus <NUM> operates the boosting mode and opens the modulating valve <NUM> and the boosting valve <NUM> (<NUM>). In this case, the cooking apparatus <NUM> may intermittently open the boosting valve <NUM> and adjust the opening duration, thereby controlling the rate of temperature increase.

The cooking apparatus <NUM> may operate the boosting mode only for the preset boosting time. In this case, the cooking apparatus <NUM> may automatically operate the normal max mode when the boosting time elapses, and may open the modulating valve <NUM>, but close the boosting valve <NUM>.

Then, the cooking apparatus <NUM> may operate the normal simmer mode when the knob deviates from the point of <NUM> degrees ("NO" in <NUM>), and may intermittently open the modulating valve <NUM> according to the position of the knob in a state of closing the boosting valve <NUM> when the knob is positioned at a point of <NUM> degrees or less ("NO" in <NUM>) (<NUM>).

For example, in the normal simmer mode, as the rotation angle of the knob gradually increases, the cooking apparatus <NUM> may increase the opening time of the modulating valve <NUM> per any one period and decrease the closing time. On the contrary, as the rotation angle of the knob gradually increases, the cooking apparatus <NUM> may decrease the opening time of the modulating valve <NUM> per any one period and increase the closing time.

When the knob is positioned at any point exceeding the point of <NUM> degrees ("YES" in <NUM>), the cooking apparatus <NUM> determines that the knob is positioned at the automatic adjustment point, and may gradually increase the opening time of the modulating valve <NUM> per any one period in a state of closing the boosting valve <NUM>.

For example, when it is determined that the knob is located at the automatic adjustment point, the cooking apparatus <NUM> may perform the operations of opening the modulating valve <NUM> for <NUM> seconds and closing for <NUM> seconds and then opening for <NUM> seconds and closing for <NUM> seconds, and then opening for <NUM> seconds and closing for <NUM> seconds, and then opening for <NUM> seconds and closing for <NUM> seconds, and then repeatedly opening for <NUM> seconds and closing for <NUM> seconds.

When the knob is again positioned at the point of <NUM> degrees, both the modulating valve <NUM> and the boosting valve <NUM> are closed, and thus gas is not supplied to the heating device <NUM>.

Herein, the disclosed embodiments may be implemented in the form of a recording medium storing instructions executable by a computer. The instructions may be stored in the form of program code, and when executed by a processor, a program module may be created to perform the operations of the disclosed embodiments. The recording medium may be implemented as a computer-readable recording medium.

The computer-readable recording medium includes various kinds of recording media in which instructions which may be decrypted by a computer are stored. For example, there may be a ROM (Read Only Memory), a RAM (Random Access Memory), a magnetic tape, a magnetic disk, a flash memory, an optical data storage device, and the like.
