Description
The present invention relates to a gas stove safety control method for preventing top glass breakage, and more particularly, to protect against abnormal overheating of radiant heat radiated from the container during cooking or flame of the gas stove to the top glass, and to accumulate continuous stress. It is invented to prevent damage due to in advance.
In general, a gas range is a cooking utensil that uses gas as fuel, and there is only a gas table and an oven facility. The more various uses of the cooking facilities are convenient to use.
An important part of the gas table is the grill, the nozzle where the heat comes from, the igniter, and the bowl where the bowl touches, and the more accurate the autoignition and the heat gauge, the more powerful the infrared grill. Has a long lifespan.
The body of the gas range is made of stainless steel with moisture, fire, and durability, which is designed to minimize gas consumption. The burners are arranged to the left and right depending on the manufacturer, and among them, the oven burner and the grill burner are included. When selecting a range, it is necessary to thoroughly review the material and precision in order to design the structure for safety and durability.
On the other hand, most of the conventional gas range to install a temperature sensor in contact with the container containing the food or water in order to prevent the cooking or the object to burn in contrary to the user's intention, the method of blocking the heat source when the abnormal high temperature is reached. It is used, but the following problems are pointed out in the safety device of the conventional gas range having such a control method.
In the conventional case, the firepower is adjusted by detecting the temperature of the container of the food, and thus a method of detecting and controlling only the temperature of the container rather than the temperature of the upper glass of the gas range made of tempered glass is adopted.
As a result, the problem of overheating of the food, ie, the container, has been solved. However, when the top plate of the range is made of glass, the glass is often damaged due to overheating when using radiant heat caused by a flame or a container, in particular, a hot pot. Even if radiant heat is generated and is normally generated, stress accumulates on the glass as the use time increases, which causes a decrease in durability of the glass and damages the top glass.
The present invention has been made to solve such a conventional problem, to prevent the top glass from being broken by overheating due to the radiant heat generated when using the gas range, the stress applied to the top glass when it is determined that it is not overheating In view of this, by correcting this, it is an object of the present invention to provide a safety control method of a gas range for preventing the top glass breakage that can prevent the safety accident and property damage that the top glass is broken due to the accumulation of stress.
The present invention for solving the above problems is a memory device for storing various data and control programs, a temperature sensor for detecting the temperature of the top glass, a flame sensor for detecting the flame, the operation unit, counting a predetermined time A control unit that generates a timer, a predetermined control program as well as various output signals, a burner driver that performs an ignition function and a gas supply amount control function in response to an output signal of the control unit, a display unit displaying various state information, and an output of the control unit. In implementing the safety control method of a gas range having an alarm for generating various alarm signals in response to the signal, determining whether the flame is detected in real time through the flame detection sensor in the control unit; Determining whether the temperature of the upper plate glass detected by the temperature sensor is higher than a reference temperature determined in the current step when a flame is detected; Judging whether the temperature of the upper glass is higher than the superheat temperature (TS ° C.) if the temperature of the upper glass is higher than the reference temperature of the current step; As a result of the above determination, if the present temperature of the upper glass is lower than the overheating temperature (TS ° C), it is determined whether the upper glass temperature is higher than the reference temperature of the current stage, and at the same time, the accumulated cumulative usage time value is loaded from the memory device and the timer is counted. Causing R to start counting time later based on the value; Lowering the thermal power by one step by a predetermined value in the current step; Determining whether the temperature of the top glass currently detected in the changed fire power is higher than the reference temperature in the current step, and returning to the previous step of lowering the fire power by one step by a predetermined value in the current step; Storing the accumulated time counted up to the present by a timer in the storage device when the present upper plate glass temperature is lower than the reference temperature in the present step as determined above; Then determining whether the current cumulative time is equal to the limit time determined in the current step, and if not, returning to the initial step; As a result of the above determination, if the current cumulative time is equal to the limit time determined in the current step, the time accumulated in the previous step and the count value of the timer are cleared, and the time and reference temperature data stored in the storage device are determined in the next step. Changing to; Determining whether the changed current step is the last step and returning to the initial step if not the last step; As a result of the determination in the above step, the step of informing to check the state of the upper glass; characterized in that consisting of.
At this time, if the temperature of the top glass is higher than the overheating temperature as a result of judging as described above, the step of blocking the gas range operation and generating a warning sound to prevent the top glass from being broken by overheating.
In addition, in the above, the cumulative use time of each step is set to be long in the initial stage, and each step cumulative time is set to gradually decrease in consideration of the deterioration rate of the top glass that increases as time passes, Each reference temperature is set to be 5-10% lower than the reference temperature of the previous step.
In the above description, the superheat temperature (TS ° C) is set to 190 to 230 ° C in consideration of the fact that the temperature of the upper glass under normal conditions is 170 to 180 ° C.
As described above, according to the safety control method of the gas range for preventing top glass breakage of the present invention, if a flame is detected by cooking various foods using the gas range, the temperature of the top glass is continuously detected. If it is higher than the overheat temperature, it cuts off the gas cooker operation and generates a warning sound to prevent the top glass from being broken due to overheating.If the temperature of the top glass is lower than the overheat temperature, the cooking time of the food is counted through a timer. Compared with the reference temperature, if the temperature is higher than the reference temperature at the stage, the thermal control is continued by one step lower than the thermal power at the stage. Eventually, if the temperature of the top glass is lower than the reference temperature at the specific stage, the timer counted previously The value stored and the accumulated time at that time If it has passed, the time accumulated in the previous step and the count value of the timer are cleared, the time and reference temperature data stored in the memory are changed to the time and reference temperature data specified in the next step, and the changed current step is the last step. It is a very useful invention, such as to check the state of the top glass to prevent the safety accidents and property damage that the top glass is broken due to the accumulation of stress in advance.
