Description

Control method upon completion of preheating of gas oven

The present invention relates to a control method when the preheating of the gas oven is completed, in particular, to precisely control the preheating temperature when the preheating is completed for the oven cooking of the gas oven and to check whether the door is opened or closed by a door open / close sensor. It can be cooked according to the characteristics of food, and if the door is not opened for a preset time after preheating, it will extinguish the oven to prevent the safety accident due to overheating in the cavity. It is about.

In general, a gas oven is a cooking apparatus comprising a gas stove for cooking food and an oven for putting food into a cavity and cooking food using radiant heat and convection heat.

Figure 3 is a view showing a conventional gas oven as described above, a stove burner 10 used to cook food such as soup on the upper portion of the gas oven, and the cavity located in the lower portion of the stove burner 10 An oven burner (14) mounted in (12) and used to cook food such as bread, and a grill portion (18) on which a grill burner (16) for cooking fish and the like are mounted are formed. The adjusting knob 20 is formed.

Therefore, when the user wants to use the gas oven, by turning on the control knob 20 of the oven or the stove burner 14, 10 according to the purpose of use, the gas is supplied through the gas valve, and then the ignition device Is driven to ignite the flame.

On the other hand, in the case of cooking using the oven burner 14, if the user selects the oven cooking and then turns on the control knob 20, the preheating starts until reaching a predetermined preheating temperature.

However, when the oven burner 14 reaches the preset preheating temperature during preheating, the oven burner 14 determines that the preheating is completed to extinguish the oven or continuously control the oven temperature until the door is turned off. If you forget, there was a problem that the safety accident occurs because the inside of the cavity 12 is constantly overheated.

The present invention is to solve the above problems, to maintain the preheating temperature by accurately controlling the preheating temperature for the oven cooking of the gas oven range so that the door can be opened or closed by the door opening and closing detection sensor Control method of food oven, and control method when preheating of gas oven to prevent the safety accidents caused by overheating in the cavity if the door is not opened for a preset time after preheating. To provide that purpose.

According to the present invention, in the control method of preheating of the gas oven, when the user selects the oven dish and turns on the oven control knob, the preheating starts to a predetermined temperature for cooking the selected oven dish, and the controller detects the temperature. The first step of determining whether the internal temperature in the preheated cavity has been increased by about 20 ° C. or more above the preset temperature by receiving a signal detected from the sensor, and in the first step, the internal temperature is about 20 ° C. above the set temperature. If the temperature rises above, the control unit determines whether the temperature inside the cavity is 30 ° C. or higher. If the internal temperature is 30 ° C. or higher, the control unit fires the oven when the internal temperature drops to 20-30 ° C., and the control unit controls the alarm to alarm the oven fire. If the door is opened by detecting the door is opened by the signal from the door open / close detection sensor, In step 2, in the second step, if the door is not opened, the controller counts the preset time (about 10 minutes) preset in the controller, controls the preheating temperature and generates an alarm sound before the set time elapses. When the set time has elapsed, the controller starts extinguishing the oven and determines whether or not the internal temperature in the cavity is lower than about -50 ° C below the set temperature. If it is lowered below the ℃ characterized in that the control unit has a fourth step to cancel the oven cooking.

1 is a block diagram showing a schematic configuration of a gas oven to which the present invention is applied, an oven cooking selection key 30 for oven cooking, and a temperature sensor 40 for detecting a temperature in a cavity 12 during temperature preheating. ), And the door opening and closing detection sensor 50 for detecting whether the door is opened or closed when cooking the oven is connected to the control unit 60, and the alarm unit 70 for generating an alarm sound is configured to be controlled by the control unit 60. It is.

The operation and effect of the present invention configured as described above will be described in detail with reference to the flowchart of FIG.

When the user turns on the oven cooking selection key 30 to cook food in the oven, and then turns on the oven control knob 20 (101), preheating starts to a predetermined temperature for cooking food in the oven. The control unit 60 receives a detection signal detected by the temperature sensor 40 that detects the preheating temperature in the cavity 12, and the preset temperature at which the internal temperature in the cavity 12 is preheated is preset. It is determined whether the rise was more than about 20 ° C (103).

When the internal temperature is increased by about 20 ° C. or more by the detection signal applied from the temperature sensor 40, the controller 60 controls the cavity 12 by the detection signal applied from the temperature sensor 40. When the internal temperature rises above 30 ° C (104), if the internal temperature is above 30 ° C, the controller 60 extinguishs the oven fire, and then, if the internal temperature drops to 20-30 ° C according to the oven fire, The control unit 60 controls the alarm unit 70 to generate an alarm sound and recognizes the fire extinguishing to the user 105. Then, the controller 60 controls the signal by a signal applied from the door open / close detection sensor 50 to detect whether the door is opened or closed. 60 completes preheating of the oven in cavity 12 once the door is open 106.

In addition, the controller 60 starts counting for a preset time (about 10 minutes) preset in the controller 60 when the door is not opened due to a signal applied from the door open / close detection sensor 50. 108, the preheating temperature is controlled until the set time elapses to maintain the preheating temperature in the cavity 12, and the alarm unit 70 generates an alarm sound to continuously recognize that the preheating is completed to the user. (109).

On the other hand, the control unit 60 starts the fire extinguishing of the oven when the count of the preset time is completed (110), and then the cavity by the detection signal applied from the temperature sensor 40 (12) determine whether the internal temperature is lower than about -50 ℃ lower than the set temperature (110), if the internal temperature is lower than about -50 ℃ lower than the set temperature to determine the oven cooking at the judgment of the control unit 60 It is canceled (112).

The present invention as described above, it is possible to cook according to the characteristics of the food by accurately controlling the preheating temperature when the preheating for cooking the oven of the gas oven, and also if the door is not opened for a predetermined time after the preheating completion It can be extinguished to prevent safety accidents caused by overheating in the cavity.
