Description

An electric cooktop having a plurality of burners (Multi Burner Electric Cooktop)

The present invention relates to an electric cooktop having a plurality of burners (fireplaces), and is designed to be controlled so as not to exceed a maximum allowable power even when a plurality of fireplaces are simultaneously operated, so that it is necessary to perform additional electric work .

Generally, an electric cooktop or an electric range is a heating device that uses electricity as a heating means. It is a device that can cook a cooking utensil such as a pot by heat generated by supplying electricity to a heating element such as a coil heater.

Such an electric cooktop is used as a substitute for a gas range. Since the electric cooktop can protect the user from various harmful substances caused by the use of the gas range, and is clean and easy to install, the installation is increasing recently.

However, the electric cooktop using the heating element has higher power consumption than other home appliances. If the electric power is continuously supplied to the heating element of the electric cooktop without considering the electric environment of the household, the power consumption is out of tolerance, There is a risk that a fire may be generated due to heat generated by the electrical connection port.

To solve this problem, an electric cooktop has been proposed in which the sum of the power consumption of the electric cooktops is limited within an allowable range by controlling the operation period of each of the heating elements. The electric cooktop sequentially The heating elements can not operate at the maximum output, the cooking time is prolonged, and there is a problem that trial and error must be experienced for a certain period of time until the user becomes accustomed.

FIG. 2 illustrates an exemplary power consumption of each burner according to a specific embodiment of the present invention.
Figure 3 illustrates, by way of example, a timing diagram according to a specific embodiment of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

The present invention relates to an electric cooktop having a plurality of burners.

The switch input unit 100 of the present invention serves to input an input signal to each burner constituting the electric cooktop.

As shown in FIG. 2, for example, the number of operating stages of each burner can be adjusted from step 1 to step 9, as shown in FIG. 2, by including the number of operating steps of each burner in the input signal.

The control unit 200 outputs a driving signal of the burner according to the signal from the switch input unit 100.

The burner driving unit 300 drives each burner according to the driving signal of the control unit 200. The voltage applied to each burner is adjusted according to the driving signal and thus the thermal power of each burner is changed.

That is, the input signal inputted through the switch input unit 100 is changed to a driving signal by the control unit 200 and outputted to the burner driving unit 300. The burner driving unit 300 controls the voltage applied to each burner according to the driving signal .

The burner driving unit 300 controls a voltage applied to each burner through phase control according to a driving signal output from the controller 200. In a specific embodiment of the present invention, a triac is used as a switching operation element If a signal is applied to the gate G, the triac switches as a relay and the voltage is applied or short-circuited according to the phase as shown in FIG. 3 to control the power consumption of each burner.

The display unit 400 serves to display the driving status of each burner (operation state and number of drive stages) of the control unit 200 according to the drive signal.

The operation of the controller 200 will be described in more detail as follows.

The control unit 200 outputs the driving signal so that the first selected burner maintains the thermal power according to the input signal inputted by the switch input unit 100. When there is a burner selected further, A difference value between the power consumption value and the power consumption value of the first selected burner in accordance with the maintenance of the thermal power of the first selected burner] and the power consumption value required when the additional selected burner maintains the thermal power according to the input signal.

[The difference between the maximum power consumption value allowed for the entire electric cooktop and the power consumption value due to the maintenance of the thermal power of the first selected burner] is greater than the power consumption value required when the additional selected burner maintains the thermal power according to the input signal The additional selected burner outputs a driving signal so as to maintain the thermal power according to the input signal input by the switch input unit 100.

[Difference between the maximum power consumption value allowed for the entire electric cooktop and the power consumption value due to the maintenance of the first selected burner] is smaller than the power consumption value required when the additional selected burner maintains the thermal power according to the input signal , The driving signal is outputted so that the additional selected burner is operated within a range not exceeding the maximum power consumption value of the entire electric cooktop and the power consumption value of the first selected burner.

If the number of additional selected burners is two or more, the difference between the maximum power consumption value allowed for the entire electric cooktop and the difference between the power consumption value due to the maintenance of the firepower of the first selected burner is set to the maximum allowable power consumption And outputs a driving signal so that each additional burner selected within the range of the power consumption distributed to each of the additional burners is operated. When three burners are operated, It is possible to display the waveform of the voltage applied to each burner at the same timing.

For example, as shown in FIG. 2, there are three burners 1, 2, and 3 in the electric cooktop and maximum allowable power consumption values for burners 1, 2, and 3 are 1.1 KW, 1.8 KW, and 2.5 KW, it is assumed that the operation stages of the respective burners are divided into the first stage to the ninth stage, and the power consumption according to the operation stages of each burner is as shown in FIG. In addition, the maximum power consumption value allowed in the entire electric cooktop is assumed to be 3.4 KW.

Under this assumption, when the input signal of the burner 2 is input first in six stages and the input signals of the burner 1 and the burner 3 are respectively inputted in the nine stages, the driving signal for the first selected burner 2 is outputted in six stages (Power consumption 1.2KW), so that the user can maintain the desired thermal power.

The maximum allowable power consumption values for the remaining burner 1 and burner 3 are 1.1 KW and 2.5 KW, respectively, and the application ratio is approximately 2: 5. [The maximum power consumption permitted for the entire electric cooktop and the maintenance of the first selected burner 3.4 - 1.2 = 2.2 KW]. When the burner 1 and the burner 3 are driven according to the input signal, the power consumption is 1.1 + 2.5 = 3.6 KW, which is larger than 2.2 K. Therefore, the burner 1 and the burner 3 can not output the input signal as the driving signal, and the remaining 2.2 KW is divided into the ratios of the maximum power consumption values permitted to the respective burners so as to be driven within the power consumption range .

That is, 2.2 x 2 / (2 + 5) = about 0.628 KW for burner 1 and 2.2 x 5 / (2 + 5) = about 1.572 kW for burner 3. Accordingly, the drive signal of the burner 1 outputs a drive signal corresponding to the fifth stage (0.61 KW) so that the power consumption of the burner 1 does not exceed 0.628 KW, and the drive signal of the burner 3 is set such that the power consumption of the burner 3 does not exceed 1.572 KW The driving signal corresponding to the fifth stage (1.38 KW) can be outputted. The drive signal of the burner 1 is outputted so that the power consumption of the burner 1 is driven at 0.6 KW, and the burner 3 is driven so that the power consumption is 1.5 KW Signal.

When three burners are activated and only two burners are left and the remaining burners stop operating, the control unit 200 determines that [the maximum power consumption allowed in the entire electric cooktop] and [the two burners being operated will maintain the firepower according to the input signal The sum of the required power consumption values] is compared.

If [the maximum power consumption allowed for the entire electric cooktop] is greater than the sum of the power consumption values required if the two burners being operated maintain thermal power according to the input signal, And outputs a driving signal so as to maintain the thermal power that follows.

If [the maximum power consumption allowed for the entire electric cooktop] is less than the sum of the power consumption values required when the two burners being operated maintain thermal power according to the input signal, the maximum power consumption value To the ratio of the maximum power consumption value permitted to each of the two burners to be operated, and outputs the driving signal so that each burner is operated within the range of the power consumption distributed to each burner.

For example, when three burners are operated and the operation of the burner 2 is stopped, the sum of the power consumption values required when the thermal power corresponding to the input signals (nine stages, respectively) of the remaining burner 1 and burner 3 is maintained is 1.1 + When the maximum power consumption value allowed for the electric cooktop is distributed at a ratio of the maximum power consumption value permitted to each of the burner 1 and the burner 3 by exceeding the maximum allowable power consumption value 3.4KW for all the electric cooktops at 2.5 = 3.6KW 3.4 x 2 / (2 + 5) = 0.971 KW for burner 1 and 3.4 x 5 / (2 + 5) = 2.429 KW for burner 2.

Accordingly, the burner 1 and the burner 3 respectively output driving signals so as to be operated by eight operation stages (the power consumption of the burner 1 and the burner 3 is 0.97 KW and 2.21 KW, respectively) or the burner 1 is operated at 0.9 KW A drive signal is outputted to drive the burner 3 and a drive signal is outputted so that the burner 3 is driven at 2.4 KW.

As described above, the first selected burner becomes the highest priority burner, the driving signal is determined so that the thermal power corresponding to the input signal can be maintained, and the highest priority burner can be set in advance regardless of the selection order. The priority is given to the operation burner in the same manner as the first selected burner, and the remaining power is distributed to the remaining burners in the manner described above.

In other words, the control unit 200 outputs the drive signal so that the predetermined highest priority burner always maintains the thermal power according to the input signal input by the switch input unit 100 regardless of the selection order, and when there is a further selected burner [The difference between the maximum power consumption value allowed for the entire electric cooktop and the power consumption value due to the maintenance of the thermal power of the highest priority burner] and the power consumption value required when the additional selected burner maintains the thermal power according to the input signal, [The difference between the maximum power consumption value allowed for the entire electric cooktop and the power consumption value due to the maintenance of the thermal power of the highest priority burner] is greater than the power consumption value required when the additional selected burner maintains the thermal power according to the input signal The additional selected burner outputs a driving signal so as to maintain the thermal power according to the input signal inputted by the switch input unit 100, The difference between the maximum allowable power consumption value and the power consumption value due to the maintenance of the thermal power of the highest priority burner] is smaller than the power consumption value required when the additional selected burner maintains the thermal power according to the input signal, The difference between the maximum allowable power consumption value and the maximum power consumption value due to the maintenance of the thermal power of the highest priority burner).

In addition, when there are two or more additional selected burners [the difference between the maximum power consumption value allowed for the entire electric cooktop and the power consumption value due to the maintenance of the firepower of the highest priority burner] is added to the maximum allowable power consumption value , And outputs a driving signal so that each of the additional selected burners is operated within the range of the power consumption distributed to each of the additional selected burners.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, Addition or deletion of a technique, and limitation of a numerical value are included in the protection scope of the present invention.
