The present invention relates to a gas range by a microcomputer control, and more particularly, to a gas range to be controlled by the microcomputer at the time setting through the encoder and a gas range control method using the same.

In general, a gas stove for liquefied petroleum gas generates sparks from an igniter by operating a control knob, and at the same time, gas is supplied to an ignition burner, ignited, and guided to a burner cap. After mixing with air in the burner body through the ignition flame induced by the burner cap is to be burned.

Referring to Japanese Patent Laid-Open Publication No. 1993-7395, the conventional gas range uses a switch to set a time or temperature for cooking food, the predetermined time set according to the time and temperature set by the pressing operation of the switch Alternatively, the process of cooking at a predetermined temperature is controlled.

The gas range control method is to perform the time and temperature setting operation by pressing the switch when setting the timer time, the setting operation should be set by pressing the corresponding time and minutes one by one. In addition, when a timer malfunction occurs, it is difficult to control the timer, which may result in a state of overheating due to prolonged use. In addition, in the conventional gas range, problems such as surge in the power supply stage (SURGE), EMI generation, etc. may occur by driving the product using an AC power source, and a safety concern may occur.

The present invention has been made in view of the above point, the gas range by the microcomputer control and gas range control using the same to be controlled by the microcomputer at the time setting through the encoder and to prevent overheating by the temperature sensor It is an object to provide a method.

The gas range further includes a temperature sensor installed in the burner and electrically connected to the microcomputer, wherein the microcomputer compares the temperature detected by the temperature sensor with a reference value set in advance in the microcomputer to determine that it is in an overheated state. It is good to be able to operate the digestive function.

Preferably, the predetermined time period during which the subsequent operation is not performed may be a time of 3 to 5 seconds.

Here, the gas range further includes a power supply unit for supplying power to the encoder, the display unit and the power input unit, the power supply unit may be installed to be interchangeably inserted into the main body.

Gas range control method through a microcomputer control according to the present invention for achieving the above object is the step of supplying power to the encoder, the display unit, the power input unit, and the microcomputer by the operation of the power input unit, the microcomputer operation of the encoder Receiving whether or not to display whether or not to display on the display unit, the first timer setting is set in the encoder by the user, after the first timer setting is made in the microcomputer whether there is a predetermined time additional operation on the encoder And determining the automatic operation of the timer when there is no additional operation during the predetermined time.

Here, the predetermined time may be a time of 3 to 5 seconds in the step of determining in the microcomputer whether there is a predetermined time additional operation on the encoder after the first timer setting is made.

The present invention is to start the timer operation by the microcomputer immediately after a certain time when setting the time through the encoder and display this to improve the user's convenience, in the event of a malfunction of the timer temperature sensor to prevent overheating for a long time It increases safety by allowing automatic fire extinguishing.

By using the battery as a power source, there is no emission of EMI from the gas range, so it does not affect external devices and there is no external surge in the power stage, thus ensuring the safety of the device. In addition, since AC power is not used, reliability of overcurrent and leakage current can be ensured when a short occurs in the AC stage.

The above objects, features and other advantages of the present invention will become more apparent from the following detailed description of the preferred embodiments of the present invention with reference to the accompanying drawings. Hereinafter, a gas range by a microcomputer control and a gas range control method using the same according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Hereinafter, the gas range 100 according to the microcomputer control according to the present invention will be described in detail with reference to FIGS. 1 and 2.

Gas range 100 according to the microcomputer control according to the present invention is the main body 110, the encoder 130 mounted on the main body 110, the display unit 140 for receiving and displaying the data set from the encoder 130, The main body 110 includes a power input unit 120 for inputting a power signal.

The gas range 100 includes an encoder 130, a display unit 140, and a microcomputer 190 electrically connected to and controlled by the power input unit 120, respectively. The microcomputer 190 may be mounted in the main body 110.

At least one burner unit 170 is arranged at an upper surface of the main body 110. Burner unit 170 is composed of a burner cap, a cover body, a burner body not shown. In addition, the general cover body is located on the upper portion of the burner body is formed of a constant width of the salt holes, by providing a fire power by discharging the flame into the salt holes. Burner unit 170 receives the mixed gas from the outside to ignite to form a thermal power source to be able to cook food.

The ignition cock 160 disposed on the front surface of the main body 110 applies a signal to form an electrical spark so as to cause a spark to the ignition means (not shown) provided in each burner unit 170.

The encoder 130 is configured to allow a user to easily set the time or temperature at a time by a dial method rather than a conventional switching method. If the user wants to cook for a predetermined time through the reservation setting, the user can perform a task using the timer function.

The display unit 140 makes it possible to see at a glance the operating situation occurring in the gas range 100 through the LCD liquid crystal window. Upon receiving notification from the microcomputer 190 that power is applied through the power input unit 120, the display unit 140 enters an operation standby mode at the same time the backlight is turned on. The standby mode refers to a state in which power is recognized through the power input unit 120. Thereafter, a signal operated by the encoder 130 is received through the microcomputer 190 to be changed into an operation mode, and a time display is displayed. The operation mode refers to a state in which a user directly applies a dial operation of the encoder 130.

Through the encoder 130, the user sets the cooking time and the like. If the user finishes the time setting after the operation of the encoder 130 and the continuous operation is not performed for a predetermined time, the microcomputer 190 automatically displays the display unit 140 without waiting for the user's start signal. Let the cooking process proceed as it is. The predetermined time period during which the operation of the encoder 130 is not made may be initially set in the microcomputer 130 in about 3 to 5 seconds. After the user finishes the time setting, the microcomputer 190 receives a continuous progress input afterwards. This can be seen as the waiting time.

The power input unit 120 functions to set the ON / OFF state as a switch type. The microcomputer 190 receives the signal from the power input unit 120 and transmits the signal to the devices (120, 130, 140) connected to the microcomputer 190.

The power supply unit 150 is provided at one side of the main body 110. The power supply unit 150 supplies power to the encoder 130, the display unit 140, and the power input unit 120. The power supply unit 150 may be installed to be inserted into the main body 110 so as to be interchangeable. Generally, AA or AAA type batteries used in electronic products may be used.

Since DC power is used as a component of the power supply unit 150, there is no AC power cord, so there is no surge of SURGE from the outside and emission of electromagnetic interference (EMI). Therefore, it is possible to minimize the influence on the gas range 100 from the harmful elements.

Hereinafter, the relationship between the burner unit 170, the temperature sensor 180, and the microcomputer 190 will be described.

The gas range 100 includes a temperature sensor 180 installed around or inside the burner unit 170. The temperature sensor 180 is required to be able to check the temperature up to at least 300 degrees. The food storage container 178 may be placed on the burner unit 170 using the holder 175. The contents of the container 178 may be heated by a thermal power source supplied through the burner unit 170, during which the temperature sensor 180 senses the temperature of the container 178 from time to time to the microcomputer 190 ).

When the microcomputer 190 is electrically connected to the temperature sensor 180 through the transmission line 195, the microcomputer 190 compares the temperature detected by the temperature sensor 180 with a reference value set in advance in the microcomputer 170, and determines that the microcomputer 190 is in an overheated state. Has a digestive function. Here, the superheated state may mean that the temperature of the container is 250 degrees or more.

That is, when the timer function set in the encoder 130 does not perform its role, there is a possibility that the thermal power source is continuously supplied to the burner unit 170, and the microcomputer 190 may be overheated. To cut off the fire source in the middle.

Hereinafter, a control method by a microcomputer in the present invention gas range will be described with reference to FIG. 3.

First, the container 178 is placed on the burner unit 170 of the gas range 100 and the power input unit 120 is operated. (S10) The encoder 130 and the display unit 140 are operated by the power input unit 120. , And the power is supplied to the microcomputer 190 (S20).

When the display unit 140 is notified by the microcomputer 190 that power is applied from the power input unit 120, the display unit 140 enters an operation standby mode. (S30) Here, the display unit 140 has not yet displayed the time display.

Thereafter, the microcomputer 190 receives whether the encoder 130 is operated and displays whether the display unit 140 displays the display (S40).

When the microcomputer 190 recognizes that the encoder 130 has been operated, the microcomputer 190 instructs the display unit 140 to display whether or not it is displayed. (S50) If the encoder 130 is not yet operated, the microcomputer is not operated. When the recognition is 190, the process returns to step S30 again.

After the step S50, the user performs the first timer setting operation through the encoder 130 (S60). When the continuous operation of the encoder 130 is performed, the set timer is displayed on the display unit 140. (S70)

When the user finishes the timer operation, that is, when it is determined that the time setting is finished by rotating the dial of the encoder 130, the microcomputer 190 continuously checks whether an additional signal comes from the encoder 130. (S80)

In other words, the microcomputer 190 continuously feeds back the first timer setting operation of the encoder 130. After the predetermined time has elapsed, the microcomputer 190 automatically generates the encoder 130. The gas range 100 is controlled to perform the operation according to the data set in step S90. The predetermined time may be set to a time of 3 to 5 seconds in consideration of a user's use habit and economical efficiency.

Even when the above step S90 is performed, when the user performs the second timer setting operation of operating the encoder 130 again, the process may return to the step S60 again. Even when the timer is operated in the same manner, if the user operates the encoder 130 at any time, the process proceeds to step S60.

When all the time set by the encoder 130 has elapsed, the microcomputer 190 may extinguish the thermal power source by blocking the mixed gas supplied to the burner unit 170. (S100)
