Electric range displaying residual heat by using storage device and method of displaying residual heat using same}

The present invention relates to an electric range for displaying residual heat by using a memory device that continuously recognizes the temperature of a top plate and guides users to it regardless of power failure, while reducing standby power consumption, and a residual heat display method using the same. .

In general, an electric range is a device that uses electricity to heat a cooking container containing food, and can be classified into a hot plate electric range, a highlight electric range, and an induction electric range.

In this way, the electric ranges classified as described above are classified according to the heating method. First, in the hot plate electric range, a heating wire built into a plate (top plate) made of a cast heats due to electric resistance to heat the cooking vessel seated on the upper surface of the plate.

In addition, the highlight electric range heats the cooking vessel through a method of heating the ceramic upper plate by generating heat from a heater built under the ceramic upper plate.

Lastly, the induction electric range heats the cooking vessel by using the electromagnetic induction heating method that uses the heat generated by the cooking vessel itself by electromagnetic induction, which will be described in more detail as follows.

That is, the induction electric range generates a magnetic field around the working coil when a high-frequency alternating current of approximately 20 to 90 kHz is supplied to the working coil of the induction heater (IH), and is positioned at the center of the magnetic field while the magnetic field is generated. When a cooking container (e.g., a magnetic metal cooking container) is placed in the cooking zone, an eddy current is generated inside the cooking container, and during this eddy current, the cooking container acts as an electric resistance to generate heat. It operates to heat the food inside the cooking container.

As the heat source of the above electric range, a heating wire heater, a coil-type radiant heater, a halogen heater, and a working coil that generates a high-frequency magnetic field are used, and the upper part of the heater is a top plate made of ceramic or high heat-resistant glass material for safety. It is provided with this.

Even after use of the electric range above, heat remains on the top plate, but most of the family members who use it are not aware of this, so if the body touches the top plate of the electric range on the side where the cooking vessel is placed, burns. There is a high possibility that safety accidents such as

Accordingly, by displaying the temperature of the heat remaining on the top plate of the electric range, all users who use the electric range can use it safely.

1 is a conceptual diagram showing a top plate structure of an electric range in which residual heat is displayed, and FIG. 2 is a block diagram showing a conventional electric range in which residual heat is displayed.

As shown, the conventional electric range in which residual heat is displayed is supplied with power from a commercial power source and a power supply unit 20 for distributing it, and a switch unit 70 and temperature through power supplied from the power supply unit 20. The heat source unit 30 and temperature through power supplied from the power supply unit 20 and the operation unit 80 for controlling the supply of power to the display unit 60 to drive and control the switch unit 70 and the temperature display unit 60 It consists of a heat source output unit 50 that controls the supply of power to the measurement unit 40 to drive and control the heat source unit 30 and the temperature measurement unit 40.

Through this, the heat source output unit 50 transmits the upper plate sensing temperature information, which is the sensing temperature of the upper plate detected through the temperature measuring unit 40 at each preset period, to the operation unit 80, and the operation unit 80 is the transmitted upper plate By outputting and displaying the sensed temperature information on the temperature display unit 60, family members, who are users of the electric range, are provided so that they can recognize the state of heat remaining on the top plate 1 of the electric range.

On the other hand, since the function of guiding the degree of heat remaining on the top plate 1 is continuously guided while the commercial power is applied to the electric range regardless of the power on/off of the electric range, a lot of standby power is consumed and energy efficiency is reduced. There was a problem of being halved

Accordingly, the conventional electric range in which residual heat is displayed reads the upper plate sensing temperature information transmitted through the heat source output unit 50 at a preset period from the operation unit 80, and the sensed temperature of the read upper plate is dangerous to the user's safety. Power is supplied to the heat source output unit 50 only when there is enough residual heat, and standby power is consumed by not automatically supplying power to the heat source output unit 50 from a temperature that is not dangerous to the user's safety. An operation method to reduce the reduction was proposed.

However, in the conventional electric range in which residual heat is displayed, when a power outage occurs, the power supply unit 20 does not receive power from a commercial power source, and thus the temperature measurement unit 40 cannot provide the upper plate sensing temperature information.

For this reason, in the case of the conventional electric range displaying residual heat, heat source output to reduce the consumption of standby power in standby mode, even though residual heat that is dangerous to the user's safety remains on the top panel (1) when it is restored after power failure. Since it is in a limited state so that power is not supplied to the side, the temperature of the top plate 1 on which the cooking zone 2 is disposed is not recognized, which causes a problem of not ensuring user safety.

Accordingly, there is a need for an electric range that displays residual heat that guarantees the user's safety by continuously recognizing the temperature level of the top plate 1 and guiding users to it regardless of power outages while reducing the consumption of standby power. Became.

The power supply unit 20 reads the power supply status signal transmitted from the operation unit 80, recognizes that a request for power supply to the heat source output unit 50 is requested, and returns from the commercial power supply 10 according to recovery after a power failure occurs. The supplied power is distributed to supply power to the heat source output unit 50 (S50).

The heat source output unit 50 controls the driving of the temperature measurement unit 40 through the supply of power distributed to the temperature measurement unit 40 (S60).

The temperature measuring unit 40 senses the temperature of the upper plate 1 and the cooking zone 2, generates upper plate sensing temperature information, and transmits it to the heat source output unit 50 (S70).

The heat source output unit 50 relays the transmitted upper plate sensing temperature information to the operation unit 80 (S80).

The operation unit 80 displays a message on the temperature display unit 60 indicating that the residual heat of the cooking zone 2 provided on the upper plate 1 is dangerous to the user's safety (S120).

The operation unit 80 records residual heat safety information in the recording device 90 indicating that the residual heat in the cooking zone 2 provided on the top plate 1 is dangerous to the user's safety (S130), so that the power has been restored after a power failure. Even at this time, based on the information recorded in the recording device 90, the residual heat temperature condition of the cooking zone 2 provided on the top plate 1 of the electric range that is not in use is accurately checked, and the temperature is enough to cause harm to the user. In this case, the power supply to the heat source output unit 50 is maintained, and the top plate 1 of the electric range is hot to guide family members who are users of the electric range.
