Description

Gas Range and Control Method

The present invention relates to a gas stove and a control method capable of setting an operation time, which are cooked for a set time according to the set cooking time of the gas stove, and are alerted visually and auditoryly a few minutes before the set time, regardless of the physical characteristics of the cooker. The present invention relates to a gas stove and a control method capable of recognizing a cooking completion time and recognizing whether gas is leaked from a gas stove so as to set an operation time to stop the gas supply in advance of the cooking set time.

In general, gas stoves can be divided into city gas and household gas cylinders. In particular, in the case of using a domestic gas cylinder, the gas cylinder is gradually worn out by repeatedly using the gas cylinder, and in some cases, the gas may leak and explode. In addition, there is a fear of gas leakage due to damage of the hose for supplying gas to the stove, the valve connecting the hose, and the connector. For this purpose, some devices are used to recognize the gas leak and close the valve installed at the outlet of the gas cylinder.However, if it is used for a long time, the installation of the battery may be forgotten, or if the battery is used, the battery may not be replaced to function properly. There is a problem. In addition, there is a gas stove with a timer set on the market, but it has only a simple timer function. For example, when cooking to take steam, or when a certain amount of time needs to reduce the intensity of fire, the timer is set for this purpose. Even though it has to wait around all the time, the effectiveness of the timer is low, and in fact, there is a problem in that the efficiency of the product is low because it is rarely used.

An object of the present invention is to solve this, and set a plurality of settings of the timer to be divided into the preliminary time and the final time, and when the preliminary time is completed, it is visually and audible to alert the person even if the ear or low vision It can be easily recognized, and also it can be recognized as a gas leak to provide convenience and stability of use. To this end, the apparatus of the present invention includes a keyboard having a plurality of timer setting input functions, a controller which recognizes a plurality of timer settings and outputs a corresponding signal and receives a gas leak detection signal when each timer is completed, and a gas corresponding to the controller. And a leak-proof first solenoid valve and a second solenoid valve operated when cooking is completed. In addition, in the control method of the present invention, it is determined whether a timer setting key is input, and when a plurality of timers are input, when the preliminary time is completed, the alarm is visually and audible, and when the final time is completed, the valve is stopped by stopping the valve operation. If a gas leak is detected, the alarm is triggered and the valve is closed automatically.

A control unit, a first solenoid valve installed in the gas cylinder itself to operate when the gas is leaked by the control unit, and a second solenoid valve installed indoors to be turned off when the gas stove operation time is completed. This is to provide a possible stove.

In addition, the control method of the present invention is cooked by a first process of checking whether or not the timer setting key input, and a second timer for preliminary time to complete before the set time before the first timer for the last time of the stove operation according to the timer setting key input A second step of alarming completion, a third step of operating the first timer for the range of operation time according to the timer setting key input, and a first valve for shutting off the gas supply when the first timer for the range of operation time is completed. Performing a fourth process of turning off, a fifth process of monitoring a gas leak regardless of the key input, and a sixth process of alerting and turning off the second valve attached to the gas cylinder when it is determined that the gas is leaked. It is to provide a gas stove control method capable of setting the time. The present invention sets a plurality of settings of the timer to separate the input into the preliminary time and the final time, and when the preliminary time is completed to alert them visually and auditory to make it easy to recognize even those who are deaf or low vision, and The gas leak can also be recognized to provide convenience and stability.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

1 is a configuration diagram of the present invention, a keyboard 10 for inputting an alarm occurrence time, which is a preliminary time set to a minute before a gas stove operation completion time and a final time, and the operation from the keyboard 10 is completed. The control unit 20 receives the input by dividing the alarm occurrence time, which is the last time and the preliminary time, and operates the timers 21 and 22, and monitors the operation of the gas leak sensor, and the gas cylinder is operated so as to operate the gas by the controller 20. (30) It comprises a first solenoid valve 31 installed in itself and a second solenoid valve 32 installed in the room so as to be off (closed) when the gas stove 40 operation time is completed. The keyboard 10 may separately install a button for setting a timer, and the first input time may be defined as a final time and the second time may be defined as a reserve time. Preferably, since the setting of the preliminary time is not essential for every cooking, it is better to set separately. Of course, one example of the control unit 20 may be a microcomputer, etc., and recognizes the input of the keyboard, drives the timers 21 and 22, and incorporates a program to drive the valves 31 and 32 necessary for cooking. shall. It is also connected to the gas leakage sensor 23 for recognizing the gas leakage as one input of the control unit 20. In addition, the other output terminal of the control unit 20 is provided with a speaker 24 for generating an alarm signal upon completion of the preliminary time timer 22, and a display unit 25 for audibly displaying the alarm signal. An example of the display unit 25 may be a light emitting diode, a seven segment or a liquid crystal display. The first solenoid valve 31 is attached to the outlet of the gas cylinder 30, the second solenoid valve 32 can easily cut off and supply the supply to the gas stove 40 near the gas stove 40 in the room. Install at the location. Preferably, the operating power of the control unit 20 is preferably to be operated by the battery (not shown) in preparation for the power failure, and is preferably installed to enable automatic charging in case of exhaustion of the battery.

Hereinafter, the process of the present invention will be described in detail using the flowchart of FIG. 2.

First, as shown in FIG. 1, a first solenoid 31 is installed at an outlet of an outdoor gas cylinder 30, and a second solenoid valve 32 is installed near a gas inlet of the gas stove 40. To be connected to the output terminals (O1, O2). In addition, the output terminal (O3, O4) of the control unit 20 is connected to the alarm speaker 24 and the display unit 25, respectively. In addition, the control unit 20 receives a power level (+) of a set level. In this state, the controller 20 checks whether the timer setting key is input through the keyboard 10 (first process 110). In the above process, if there is no timer setting key input, it waits until there is an input, and if there is an input, sets a time by dividing the last time of the range movement and a preliminary time for alarm generation. The timers 21 and 22 are operated by the time setting. At this time, when the timer 22 set as the preliminary time is completed, the control unit 20 recognizes this and generates the set alarm message or alarm sound to the speaker 24 and also recognizes the display unit 25 visually. do. As an example of the display, it may be embodied by the oscillation light of the light emitting diode or may be displayed by a character using a liquid crystal, so that a person who does not have good hearing can easily recognize it (second process (120, 130)). Then, for example, the user can reduce the amount of gas supplied when cooking, and can moisten the rice, and scientifically cook various kinds of foods in time. When the operation of the first timer 21 set as the final cooking completion time is completed in this way, the second solenoid valve 32 is operated through the output terminal O2 to shut off the gas supply to the stove 40 to complete the cooking. (Third process (120,140)). On the other hand, prior to the above processes (first to third processes 110-140), the controller 20 always monitors the gas leakage input from the gas leak sensor 23 (a fifth process 150). When the gas leak signal is detected in this manner, an alarm message (for example, gas leak!) That has been set is output through the speaker 24, and the first solenoid valve 31 installed in the gas cylinder 30 is provided. It is driven to close to prevent further gas leakage to prevent large accidents in advance (sixth step 160). In the case of the present invention, since the gas stove 40 is always used every time it is cooked, if there is an abnormality in the battery of the control unit 20, the alarm is immediately alerted. ) You can recognize it when you use it and replace it immediately to eliminate it.

As described above, the present invention inputs two types of timers to alert the preliminary time before the cooking completion time to be suitable for the cooking requiring the control of the fire. It can also provide convenience to hurry up the preparation of the next dish when cooking is continued.Also, each alarm can be visually and audibly alerted so that users with poor vision or hearing can easily overcome it and use it. Regardless of whether the gas leak is detected first, it can be alarmed and the valve attached to the gas cylinder can be shut off to prevent large accidents caused by the gas leak.
