Description

TECHNICAL FIELD [0001] The present invention relates to a gas-type steam convection oven having a turbo function, and a control method thereof. BACKGROUND ART [0002]

The present invention relates to a gas-type steam convection oven and a control method thereof, and more particularly, to a gas-type steam convection oven and a control method thereof, and more particularly to a gas-type steam convection oven which shortens preheating time of an oven and shortens a cooking time by allowing a cooking water to be introduced into a cooking chamber, Type steam convection oven having a turbo function and a control method thereof.

Generally, the steam convection oven allows the food to be cooked under appropriate temperature and humidity conditions by spraying steam into the cooking chamber. When the steam generator is to be cooked in the steam mode, the steam generator injects steam into the cooking chamber Is cooked while the humidity condition of the cooker is maintained.

Meanwhile, a gas type steam convection oven is a cooking device for obtaining a thermal power by using gas as a fuel, and generates steam by using a gas combustion device to control the cooking chamber temperature.

The gas type steam convection oven includes a cooking chamber, a door that opens and closes an open front portion of the cooking chamber, an operation unit that adjusts the temperature of the cooking chamber, a heat source unit that supplies heat and steam to the inside of the cooking chamber, And a control unit for controlling the control unit.

As a method of controlling the temperature in the cooking chamber of the gas-type steam convection oven, the combustion amount is controlled by controlling the rotation speed of the combustion fan to control the temperature of the thermal power and the cooking chamber.

That is, if the rotation speed of the combustion fan is increased, the thermal power is increased and the temperature in the cooking chamber is increased faster, so that the preheating time and the cooking time in the cooking chamber can be shortened.

However, the conventional gas-type steam convection oven has been divided into two stages, i.e., a burner mode and a burner mode, which are classified according to the rotational speed of the combustion fan.

In the conventional steam convection oven, the rotational speed of the combustion fan is increased to increase the thermal power. However, the rotational speed of the combustion fan is increased only by increasing the rotational speed.

That is, although the thermal power is increased by increasing the rotational speed of the combustion fan, when the rotational speed of the combustion fan exceeds a certain range, the noise due to the high-speed rotation of the combustion fan becomes large.

In addition, the temperature rise rate of the cooking chamber can not be increased proportionally compared with the case where the rotational speed of the combustion fan is increased.

Further, when the rotational speed of the combustion fan of the steam convection oven is increased to exert a high heat for a long period of time in a state in which the thermal power is intensified, the heat exchanger and the inner cylinder may be deformed.

Hereinafter, the present invention will be described with reference to FIGS. 1 to 6. FIG.

FIG. 1 is a partially exploded perspective view showing the construction of a gas-type steam convection oven according to an embodiment of the present invention. FIG. 2 is a side view of FIG. 1, which is a steam convection oven equipped with a turbo-function button.

Such a gas-type steam convection oven comprises a cooking chamber 30, a door 40, an operating unit 20, a control unit 10, and a heat source unit 50 provided at one side of the main body.

The cooking chamber 30 is a space for storing food to be cooked and the door 40 is opened and closed on the opened portion of the cooking chamber 30 so as to have airtightness so that the sealing function can be clearly made.

The heat source unit 50 supplies heat and steam to the inside of the cooking chamber 30. In the embodiment of the present invention, since the gas is used as fuel, the burner 51 burns the gaseous fuel to obtain a thermal power , And a combustion fan (52) for controlling the thermal power of the burner (51).

The operation unit 20 is located on the front surface of the convection oven and controls the temperature of the cooking chamber 30. [

A command for all cooking operations such as turbo function setting, cooking temperature setting, and combustion mode setting is performed through the operating unit 20 by determining the cooking state of the food to be cooked through the operation unit 20. [

The control unit 10 controls each part in accordance with an input signal of the operation unit 20 and performs a cooking operation by executing a command for all cooking operations indicated through the operation unit 20. [

That is, the control unit 10 determines the function of cooking with the turbo function or the general function according to the command inputted by the operation unit 20, and controls the rotation speed of the combustion fan 52 of the burner 51.

The controller 10 includes a microcontroller unit (MCU) 100 for automatically selecting and operating commands for turbocharger combustion, turbocharger combustion, and combustion stop according to the cooking set temperature and the cooking chamber temperature in the turbo function .

The microcontroller unit (MCU) 100 includes a microprocessor 110, an input key 120, a temperature sensor 130, a timer 140, and a combustion fan driving circuit 150.

The microprocessor 110 processes signals input from the input key 120, the temperature sensor 130, and the timer 140.

The input key 120 sets a cooking temperature or a cooking time in the microprocessor 110 or inputs other cooking conditions.

The temperature sensor 130 senses a temperature inside the cooking chamber 30 and applies a signal to the microprocessor 110.

Accordingly, the temperature sensor 130 provides a condition for discriminating the turbo lighter mode, the turbo lighter mode, and the combustion lag mode in performing the turbo function according to the embodiment of the present invention.

The combustion fan driving circuit 150 controls the rotational speed of the combustion fan 52 provided in the heat source unit 50 of the gas-type steam convection oven according to an instruction from the microprocessor 110.

The control unit 10 is divided into a cooking mode of a burner mode, a weak burning mode, a turbo burner mode, a turbo burner mode, and a burn-down mode, Allows you to perform tasks automatically during operation.

The lubrication demand is set so that the rotational speed of the combustion fan 52 is set to [the number of times of laminating and smoothing], and is cooked.

In the weak combustion mode, the rotational speed of the combustion fan 52 is set to [the weak combustion rotational speed] so as to be cooked.

The turbine lubrication amount is set so that the rotational speed of the combustion fan 52 is set to [the total number of lunting and smelling cycles + the number of revolutions] to be cooked.

In the turbo-weak combustion mode, the rotational speed of the combustion fan 52 is set to [the number of lunting and smashing cycles + the number of rotations] so as to be cooked.

(However, the condition is [α rotation number]> [β rotation number].)

Therefore, it can be understood that the turbocharger mode and turbocharger combustion mode by the turbo function are stronger combustion modes than the conventional lubrication mode.

The combustion stop mode is a non-combustion state in which the burner 51 does not burn fuel gas.

The embodiment of the present invention compares the cooking chamber temperature detected by the temperature sensor 130 with the adjustment value of the cooking set temperature set through the input key 120 to determine whether the turbocharger burner mode or the turbo burner mode or the burn- do.

The adjustment value of the cooking set temperature is set to be the boundary temperature between the turbofan soft burn mode and the turbofan soft burn mode and the boundary temperature between the turbo weak burn mode and the combustion stop temperature [ Lt; / RTI &gt; (However, the condition of B ° C <A ° C)

Therefore, the range of turboferlique burn-in by the turboferment mode is [cooking chamber temperature] <[cooking setting temperature-A ° C], and the turbo weak burning range by the turbo- ] &Lt; = [cooking chamber temperature] &lt; [cooking setting temperature-B C], and the combustion stopping mode is set in the range of [cooking set temperature-B C]

3 is a schematic circuit diagram for realizing a control method of a gas-type steam convection oven having a turbo function according to an embodiment of the present invention.

The microprocessor 110 processes the signals input from the input key 120, the temperature sensor 130, and the timer 140 to control the combustion fan driving circuit 150.

The input key 120 is included in the operation unit 20 and is a user-selectable selection key. When the gas convection type oven is used, each function is selected and set.

The temperature sensor 130 is installed inside the cooking chamber 30 to sense the temperature of the cooking chamber, and the temperature of the cooking chamber is necessarily required in setting the cooking condition.

The timer 140 functions to set the cooking time and the like.

Hereinafter, the control operation of the microprocessor 110 will be described with reference to FIG.

FIG. 4 is a flowchart of a control operation performed by the microprocessor 110 shown in FIG. 3, in which a command for using a gas-type steam convection oven according to an embodiment of the present invention is inputted by the user through the input key 120 Lt; / RTI &gt;

In step S10, the user selects the turbo function and commands the turbo function through the input key 120. The microprocessor 110 determines the input signal from the input key 120, And proceeds to the next step.

That is, in the case of using the gas-type steam convection oven, it is determined whether the turbo function can be performed or not.

In step S20, the microprocessor 110 determines whether or not the state of the gas-based steam convection oven is being cooked and determines whether to perform the turbo function.

If the gas-type steam convection oven is not in the cooking state, the process of step S20 is repeated. If it is determined that the oven is in the cooking state, the process proceeds to step S30.

Step S30 is a step of comparing and processing the temperature of the cooking chamber and the cooking set temperature, respectively, and it is a step of determining whether or not the conditions of [cooking chamber temperature] &lt; [cooking set temperature-A DEG C] are satisfied.

At this time, the temperature inside the cooking chamber is sensed by the temperature sensor 130 installed in the cooking chamber 30, and a signal value is applied to the microprocessor 110 to thereby determine an accurate [room temperature] And compares the detected [cooking chamber temperature] with the [cooking set temperature-A ° C], which is the cooking set temperature adjustment value inputted by the user through the input key 120.

If the condition of [cooking chamber temperature] &lt; [cooking set temperature-A DEG C] is satisfied through the above comparison, it is commanded to perform the operation of the turboshaft (S40) since the conditions of the turbocharger are satisfied.

Accordingly, the rotational speed of the combustion fan 52 in the turbocharger (S40) mode is set to [the number of luns and tales + the number of revolutions].

However, if the condition of [cooking chamber temperature] &lt; [cooking setting temperature-A DEG C] is not satisfied, proceed to the next step S50.

Step S50 is a step of determining whether or not the condition of [cooking chamber temperature] <[cooking set temperature-B ° C], which is another condition, is satisfied.

That is, the temperature sensing sensor 130 installed in the cooking chamber 30 senses the temperature inside the cooking chamber, and a signal value is applied to the microprocessor 110 to determine the [cooking chamber temperature] [Cooking set temperature-B ℃] entered by the user are compared with each other.

If the condition of [cooking chamber temperature] <[cooking set temperature-B ° C] is satisfied through the above comparison, it is instructed to perform the turbo weak combustion (S60) operation since the turbo weak combustion condition is established.

That is, the operation of S60 is performed because the condition of [Cooking set temperature-A ° C] ≤ [Cooking room temperature] <[Cook set temperature-B ° C] is satisfied.

Therefore, the rotational speed of the combustion fan 52 in the turbofaner combustion (S60) mode is set to be [the number of lapsed burning times + the number of rotations] so as to be cooked.

However, if the condition of [cooking chamber temperature] <[cooking setting temperature-B ° C] is not satisfied, the process proceeds to the next step S70.

The step S70 is a stage in which the burner 51 does not need to generate a thermal power as a combustion stopping step. That is, since the condition of [cooking set temperature-B ° C] ≤ [cooking chamber temperature], no further thermal power is required.

(However, the condition of B ° C <A ° C)

FIG. 5 is a graph showing changes in the temperature of the cooking chamber during each step of the turbo function according to the embodiment of the present invention.

As can be seen from the graph, the turbocharger burner, the turbo boiler burner, and the turbocharger burner were set at the boundary between the cooking set temperature-A ° C and the cooking set temperature-B ° C, And the combustion is stopped.

6 is a schematic circuit diagram for realizing a control method of a gas-type steam convection oven having a turbo function according to another embodiment of the present invention.

The microcontroller unit (MCU) 100 further includes an exhaust hole regulating valve driving circuit 160 for regulating an exhaust hole of the heat exchanger exhaust unit 60 in response to a command from the microprocessor 110.

The heat exchanger exhaust unit 60 is provided with an exhaust hole control unit for opening and closing an exhaust hole and the size of the exhaust hole is adjusted by an exhaust hole control unit driving circuit 160 for controlling the opening and closing state of the exhaust hole control unit Thereby providing optimal combustion conditions.

In one embodiment, the exhaust hole adjusting member changes the specification of the exhaust hole according to the opening angle of the lid hinged to one side, May be driven by the power of a solenoid operated by a power source applied by the exhaust hole regulating valve driving circuit (160).
