Abstract

The present invention relates to a stove which gas or electricity can be automatically controllable according to the temperature of a pot set by a user. A temperature measuring unit of the present invention uses a contact type thermistor or non-contact type infrared rays thermometer of which the location is movable and measures the temperature of a pot or food accurately, thereby automatically controlling gas or electricity based on the measured temperature. When a user inputs a desired temperature range and rotation range of gas control valve, gas or electricity can be automatically controlled based on the corresponding temperature. If the temperature rises above a certain degree (around 110 degree), gas or electricity is completely blocked, thereby preventing overheating and fire accidents.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a gas stove,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a stove which automatically adjusts the intensity of a gas fire or an electric heating value according to a temperature of a container. The present invention can also be applied to gas or electric ranges, where the stove is considered to include a stove.

Generally, when the water in a vessel (pot, pot, etc.) starts to boil when cooking, reduce the size of the fire. If there is no person nearby, a large fire may occur if water is completely evaporated and the temperature of the container continues to rise.

The conventional gas stove 110 includes a gas nozzle part 111 which receives a gas from the gas pipe and discharges the gas into the air and a heating part 113 combined with a sparker 112 for burning the gas nozzle part 111 A control valve 114 for controlling the amount of gas discharged to the gas nozzle unit 111 and a container support provided on the gas nozzle unit 111 Includes a heating unit 113 that receives electricity from a power source and discharges heat to the heat through the heating wire 121 and a control valve 114 that adjusts the heating value by varying the electric resistance of the heating wire 121 in the heating unit 113 (FIG. 2).

The products of the gas or electric stove are roughly divided into two functions. One is to adjust the heat intensity by manually adjusting the gas supply amount or the electric heating value, and the other is to apply the gas only to the gas range. After the water has completely evaporated, there is a gas stove that completely blocks the valve if the temperature of the vessel is above a certain temperature (eg, 101 ° C) [1-3].

In the latter case, several patents have been introduced [1, 2, 3], one of which is a gas stove overheat protection device [1]. This device uses an overheat detection sensor installed at the center of a heating part (a burner) to switch the overheated state of the bottom of the vessel to current and operate the electromagnet by the current to shut off the gas passage. However, this technology is not specific for the overheat detection sensor, and the precision of the electromagnet is not practical and remains at the concept level and is not commercialized. There is a gas automotive single stage device using an infrared sensor [2]. In this apparatus, a sensor is provided at the center of the heat generating portion and a gas shutoff device is used. However, the other is that the temperature sensor is an infrared sensor, the gas shutoff device is a solenoid valve, Is installed. However, a serious disadvantage in the reference [1,2] is that the temperature sensor is too close to the gas fire to accurately measure the temperature of the container, and the sensor is burned or the life is shortened due to high temperature.

In addition, a patent for measuring the temperature of the lid of the container or the soup in the container (an apparatus for preventing overheating of the cookware and its method [3]) has been introduced with an infrared sensor. This is because the infrared temperature sensor is fixed away from the container, It consists of a simple on / off solenoid valve that opens and closes the gas only when the temperature is high. The invention [3] is a conceptual level of generalized technology, and its practical operability is limited. That is, since the infrared temperature sensor is fixed far away from the container, the temperature can not be accurately measured (the non-contact infrared temperature sensor needs to measure the temperature at a close range), and a simple method to be.

When the food is actually cooked in the gas stove 110 or the electric stove 120, the food or the like in the container is cooked and gradually reduced in the amount of gas or electricity supplied to the control valve 114, ) And then completely turned off. Furthermore, if you forget to cook food with a stove (such as cleaning or going out), if the broth of the container is completely crushed, you can turn off the control valve 114 and automatically reduce the heating value, I think that a device that completely cuts off the electricity supply is necessary.

However, in the currently commercialized stoves, there is no example in which the above situation is automated by automation. The present invention completely solves the disadvantages of the above situation.

The present invention provides the following means for solving the above problems (FIG. 3).

1. There should be temperature measuring means (200) for measuring the temperature of the container placed on the stove, and for measuring the temperature safely and accurately.

2. A torque generating means 300 for accurately turning the control valve 114 so that the intensity of the gas fire (or the calorific value) can be automatically adjusted according to the temperature measured by the temperature measuring means 200 is needed.

3. If the measured temperature is within the range of room temperature to 70 degrees or less, the control valve 114 is left as it is in the initial state. If the measured temperature is 70 to 80 degrees, (Or electricity) is shut off when the temperature exceeds 105 ° C. The gas (or electricity) supply can be controlled according to the temperature of the vessel A temperature rotation range input control means 500 is required.

4. In step # 3, the temperature rotation range input control unit 500 includes a numerical value input unit 510 for inputting a temperature range and an opening / closing range of the valve, and a microprocessor unit 520 ).

5. Time measuring means (also referred to as a timer) for measuring the remaining time so that the gas (or electricity) is continuously supplied for a predetermined time even in the range of less than 80 to 100 degrees and then the gas (or electricity) ) 800 and a control means for shutting off gas (or electricity) supply are also necessary.

6. A voice alarm means 900 is also required to indicate when the preset temperature has been reached in Steps 2 to 5 or when the timer has reached the contracted time.

7. A numerical value display unit 1000 (e.g., a display) is also required to display the measured temperature, the elapsed time of the timer, and whether or not the voice alarm unit is set.

Generally, when cooking steamed stoves, when the soup begins to boil when the temperature rises, the gas fire (or the amount of electricity generated) is reduced. Also, if you are busy with cleaning while cooking, forget about boiling soup, and almost all of the soup is evaporated, sometimes ruining the dish. Moreover, if you are in a hurry in the morning, you can go to work with the stove on, which could cause a major fire. However, according to the present invention, it is possible to control the gas (or electricity) supply amount according to the temperature of the container, thereby reducing unnecessary energy waste and preventing property damage caused by forgetting to boil the stew.

The configuration and function of the present invention are the same as those of the third to fourth embodiments.

The present invention relates to a conventional gas stove 110 consisting of a heat generating part 113 which receives gas from a gas pipe and generates gas fire and a regulating valve 114 which regulates the amount of gas supplied to the heat generating part 113 (FIG. 1), temperature-measuring means 200 capable of moving the position; An automatic regulating valve unit 310 for automatically regulating the amount of gas supplied to the heat generating unit 113 according to the temperature measured by the temperature measuring unit 200; A motor driving unit 400 for transmitting rotational force to the regulating valve 114 in the automatic regulating valve unit 310; And a power supply unit for supplying electricity to the temperature measuring unit 200 and the motor driving unit 400. The temperature measuring unit 200 is provided with a temperature control unit A rotation range input control means 500 is additionally provided (FIG. 3 to FIG. 4).

The function of the present invention can be applied to electric stoves in the same way. The present invention is applied to a conventional electric stove 120 including a heating unit 113 for receiving electric power from a wire and emitting heat energy to the heating unit 113 and a control valve 114 for controlling the amount of electricity supplied to the heating unit 113 A temperature measurement means 200 capable of positional movement; An automatic regulating valve unit 310 for automatically regulating the amount of heat generated by electricity supplied to the heat generating unit 113 according to the temperature measured by the temperature measuring unit 200; A motor driving unit 400 for transmitting rotational force to the regulating valve 114 of the automatic regulating valve unit 310; And a power supply unit for supplying electricity to the temperature measuring unit 200 and the motor driving unit 400. The temperature measuring unit 200 is provided with a temperature control unit And a rotation range input control means 500 are further provided (FIG. 3 to FIG. 4).

The temperature measuring means 200 measures the temperature of the food or the temperature of the container in the container, and there is a contact method and a non-contact method. The contact type temperature measuring means 201 is brought into contact with the upper end or the lid of the container or locked in the food. When the contact type is used in the present invention, the thermocouple 210 or the thermistor 220 may be used as an embodiment of the contact type temperature measuring means 201. The noncontact type temperature measuring means 202 can directly measure the container lid or the soup at a short distance so that the temperature can be measured even when the noncontact temperature measuring means 202 is not in contact. In the present invention, the non-contact type temperature measuring means 202 uses the infrared thermometer 230. Since the infrared thermometer 230 can not measure the temperature at a long distance because the intensity of the infrared rays is weak, Measure at close range. Since the infrared thermometer 230 is a general idea widely used in other technical fields, the infrared thermometer 230 in the present invention is extremely common and can not be regarded as a patented technology. However, in order to accurately measure the temperature, It is very important to be close to the measuring object. Therefore, it is necessary to define the arrangement state of the thermometer when using the infrared thermometer 230 and when not using it.

The temperature measuring means 200 may use one or more temperature measuring means 200 and may use either a contact type or a non-contact type temperature measuring means or a combination of both (see FIGS. 3 to 4 Degree).

When the temperature measuring means 200 is not in use, the temperature measuring means 200 is fixed to a fixing table 600 which fixes the temperature measuring means 200. When the temperature measuring means 200 is used, the temperature measuring means 200 can be pulled from the fixing table 600, A position disposing means 700 is required to prevent the position from changing. The position locating means 700 may be formed by connecting the fixing table 600 and the temperature measuring means 200 so that the temperature measuring means 200 can be placed close to or close to the container, Or a non-elastic stretchable corrugated pipe 720 such as a stainless steel corrugated pipe (trade name) can be used (FIG. 3 to FIG. 4).

The winding wire and the sifter 710 are constituted by a sheave 711 fixed to the fixing table 600, a wire 712 wound around the sheave 710 and a sliver 713 attached to an end of the wire 712, A temperature measuring means (200) is attached to the syringe. The electric wire 712 may have a function of extending the electric wire 712 to a long length when the electric wire 712 is pulled. When the electric wire 712 is used, the electric wire 712 may be extended to the container position, And then the container 713 is used to fix the container to the container (FIGS. 3 and 5).

When the fixing table 600 and the temperature measuring means 200 are connected to each other by the inelastic stretchable corrugated pipe 720 such as the stainless steel corrugated pipe (trade name), since the temperature measuring means 200 remains at the position where the temperature measuring means 200 is pulled, It is much more convenient to use than the portion 710, but the effect of hiding the inelastic stretchy corrugated pipe 720 is lost.

The automatic regulating valve unit 310 may include a regulating valve 114 of a conventional gas stove 110 or an electric stove 120 and a regulating valve rotating gear 313 to the regulating valve rotating shaft 312 (FIG. 6).

The motor driving unit 400 includes an electric motor 410 and a motor gear 430 formed on the electric motor rotating shaft 420 provided therein. The motor gear 430 meshes with the control valve rotary gear 313 of the automatic control valve unit 310 so that the control valve 114 is rotated in accordance with the rotation of the electric motor 410, . As an example of the electric motor 410, a step motor is used, which has a function of rotating by a predetermined angle according to an input signal (FIG. 4).

In order to effectively control the calorific value according to the temperature of the container, the temperature range and the rotation range of the control valve 114 must be set accordingly. Therefore, the present invention may include a temperature rotation range input control unit 500 . The temperature rotation range input control means 500 includes a numerical value input means 510 for setting a rotation range of the control valve 114 in accordance with a temperature range and a temperature range and a microprocessor 520 for executing the logic (Fig. 4).

In addition, the following components may be additionally provided for safety and convenience of the user (FIGS. 3 to 4).

First, since the boiling temperature of the food is in a specific temperature range (typically 100 to 105 degrees), the time measuring means 800 for completely shutting off the gas or electricity supply when the gas or electricity is supplied for a predetermined time, (FIG. 4).

Second, the present invention may further include a voice alarm unit 900 to provide a voice notification service that the current temperature and thus the calorific power is reduced each time the control valve 114 is rotated by the motor driving unit 400 . In one embodiment of the voice alarm means 900 of the present invention, the current temperature of the container is 95 degrees or the current temperature is 100 degrees, and the food is boiling, and is automatically shut off after 10 minutes. And so on.

Third, the temperature input to the temperature rotation range input control means 500, the rotation range of the control valve 114, the time remaining until the end of the time measurement means 800, and the alarm setting of the voice alarm means 900, The numerical value display unit 1000 may be provided. As an example of the numerical value display unit 1000, a liquid crystal display or a graphene display may be used.

Fourth, at least the power source of the temperature measuring means 200 and the motor driving unit 400 among the constituent elements of the present invention can be turned on simultaneously when the control valve 114 is turned on.

Since the container lid and the food temperature are accurately measured in real time by the temperature measuring means 200, the heating state of the container can always be known, and the temperature rotation range input control means 500 The cooking temperature and the corresponding rotation range of the control valve 114 can be input so that the gas (or electricity) supply amount can be reduced by itself when the food reaches a specific temperature. In addition, at a temperature higher than the boiling point of the food (eg 110 ° C), it is considered that the soup is crushed and the gas (or electricity) supply can be completely shut off.

One embodiment of the operating sequence of the present invention is similar to the seventh aspect. First, the present invention is turned on to start cooking the food, and the temperature rotation range input control means 500 inputs the cooking temperature and the rotation range of the control valve 114 accordingly. Then, the control valve 114 of the stove is returned to supply gas or electricity. For example, if the measured temperature is in the range of room temperature to 80 degrees, it is maintained at the position of the regulating valve 114 in the initial state. If the measured temperature is 80 to 90 degrees, 3, and if it exceeds 110 degrees, it is judged that the broth of the container is fried and the control valve 114 is completely closed to cut off gas (or electricity) supply.

On the other hand, it is possible to include a function of setting the gas fire to increase again when the temperature of the vessel falls, but in this case, it is important to remember that the risk of gas emission is greatly increased because the gas supply amount is increased even when the flame of the gas stove is turned off do.
