DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram for explaining a temperature detecting function according to the present invention and a power saving device of a kitchen cooking apparatus having a battery.

1, the temperature-sensing function and the power-saving device of a kitchen cooking apparatus equipped with a battery according to the present invention include a kitchen cooking apparatus 100, a micro control unit (MCU) 110, a temperature conversion unit 111, A temperature detection section 112, a high temperature / low temperature region switching instruction section 113, a high temperature / low temperature changeover circuit 120, a temperature detection section 130, a power supply circuit 140 and a battery 150.

The kitchen cooking apparatus 100 is a gas range, which is an example of a kitchen appliance capable of temperature detection, equipped with a battery, and having one or more cooking utensils.

The microcontroller unit (MCU) 110 determines the temperature of the burner serving as the cooker, changes the temperature detection frequency and operation of the gas range according to the current temperature, do.

To this end, the microcontrol unit 110 is composed of a cooking apparatus temperature conversion unit 111, a temperature determination unit 112, and a high temperature / low temperature region transfer instruction unit 113.

Here, the cooking apparatus temperature conversion unit 111 converts the temperature from the cooking apparatus to a temperature that can be determined by the temperature determination unit 112.

The temperature judging unit 112 judges the temperature converted by the cooking apparatus temperature converting unit 111. [

The high-temperature / low-temperature region switching instructing section 113 instructs the number of times and the operation to detect the temperature in the high-temperature and low-temperature regions to be different according to the temperature judged by the temperature judging section 112. At this time, the number of times of temperature detection in a region where current consumption is high is reduced.

The high-temperature / low-temperature-changeover circuit 120 detects the number of times of detection in the high-temperature, low-temperature, and temperature-non-detection burner in the temperature detection unit 130 and the number of times of detection in the burn- Instruct the supply to be different.

The temperature detecting unit 130 may be a thermistor as an example of a sensor for detecting the temperature of the burner of the kitchen cooking apparatus 100.

When there are a plurality of burners, the first to n-th temperature detecting units 131, 132, and 133 are provided. The temperature detector 130 detects the temperature of the high / low temperature or temperature non-detection burner according to the switching of the high / low temperature switch circuit 120.

The power supply circuit 140 supplies the power of the battery 150 to the high / low temperature switch circuit 120.

The temperature detecting sensor of the temperature detecting unit 130 according to the present invention detects the temperature by receiving a voltage applied to the sensor by changing the resistance according to the temperature. Since the temperature detecting sensor has a varying range of resistance depending on the temperature, In a cooking appliance such as a range, the temperature can be measured by changing the partial pressure resistance in a low temperature region of 100 ° C or less and a high temperature region of 100 ° C to 350 ° C.

As described above, the voltage-dividing resistance is set differently according to the temperature range, so that the current temperature can be determined while the temperature is measured, and the current consumption of the battery can be reduced by reducing the temperature sensing time in the temperature region where the consumption current is large.

In order to reduce the consumption current by the temperature detection, the unused burner is fixedly performed in a high-temperature or low-temperature region where the consumption current is high, thereby reducing consumption current. Or a circuit that cuts off the power supply to the thermistor, thereby reducing current consumption.

FIG. 2 is a view for explaining an example of detecting a high-temperature region of a high-temperature / low-temperature-changeover circuit in a power saving device of a kitchen cooking apparatus having a temperature detecting function and a battery according to the present invention, Temperature region of the high-temperature / low-temperature-change circuit in a power-saving device of a kitchen cooking apparatus having a battery.

In the power saving apparatus of the kitchen cooking apparatus having the temperature detecting function and the battery according to the present invention, the high-temperature / low-temperature switching circuit 120 includes a CPU for controlling the number of times of detection and operation according to high / low temperature detection, A transistor Tr whose one end is connected to the collector of the first resistor R1 and the other end of which is connected to the collector and the emitter of the transistor Tr and whose one end of the second resistor R2 is connected to the collector, And the other end thereof is connected to a thermistor serving as a detection sensor for detecting the temperature of the cooking utensil and is supplied with the voltage Vcc from the battery in accordance with the detection of high temperature and low temperature to control the number of times of temperature detection and operation of the gas range burner through the thermistor .

As shown in FIG. 2 and FIG. 3, the high temperature region sensing is performed by alternately performing temperature sensing in a high temperature region and a low temperature region at a specific time. Since the resistance of the thermistor is high when the present temperature is lower than a specific temperature, Data of the high temperature region shown in Fig. 2 need not be detected quickly.

Therefore, it is possible to detect the high temperature region once after the detection in the low temperature region n times (for example, three times to ten times). For reference, the specific temperature can be changed according to the resistance constituting the high-temperature / low-temperature-change-over circuit 120. A value between 100 and 150 ° C can be set as a low temperature reference, and an unused burner (unused burner) Since data is not required, only the low-temperature region can be detected through the low-temperature region detection in which the consumption current is small.

For reference, the resistance of the thermistor decreases as the temperature increases, and as the resistance decreases, the consumption current increases. Accordingly, in order to increase the decomposition ability of the input of the thermistor, the data input through the path as shown in FIG. 2 is utilized.

Next, the microcontroller 110 sets the temperature detection to perform the temperature detection at a predetermined time interval that is differentiated from the classified cooker, and sets the temperature detection of the unused cooking device to the non-detection (S120).
