Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

The present disclosure provides a heating module 10, as shown in fig. 1, the heating module 10 includes a heating assembly 20 disposed in cooperation with a vessel (not shown in fig. 1), a voltage detection module 50 and a controller 30; the heating assembly 20 and the voltage detection module 50 are both connected to the controller 30.

Wherein the heating assembly 20 is used to connect an alternating current to heat the liquid in the vessel.

The voltage detection module 50 is used for detecting the voltage of the alternating current and sending the voltage to the controller 30.

The controller 30 is configured to determine a time sequence of the heating assembly 20 according to the voltage of the alternating current, the time sequence including a plurality of heating times, a plurality of interval times, and an arrangement order between the plurality of heating times and the plurality of interval times, and control the heating assembly 20 to heat the liquid according to the time sequence.

In the related art, the voltage of the ac power is usually set to 220V by default, but in practical applications, the voltage of the ac power is not stable, and may be greater than or less than 220V, and if the controller 30 always instructs the heating assembly 20 to heat according to the default 220V, the heating power of the heating assembly 20 may be sometimes high or sometimes low, which may affect the cooking effect. The voltage detection module 50 may detect the real-time voltage of the ac power and then transmit the real-time voltage to the controller 30, so that the controller 30 may determine the heating time and the interval time of the heating assembly 20 according to the real-time voltage of the ac power.

For example, assuming that the user needs to heat the liquid in the vessel to boiling, if the liquid is always heated at full power, an imbalance in the temperatures of the upper portion and the lower portion of the liquid may occur, and therefore the controller 30 may first control the heating assembly 20 to heat at full power to a preset temperature threshold, where the preset temperature threshold may be a difference between the boiling point of the liquid and a fixed value, such as a difference between the boiling point of the liquid and 15 ℃, or may be a fixed temperature value, such as 80 ℃, which is not limited by the embodiments of the present disclosure. After the liquid temperature reaches the preset temperature threshold, the liquid can be continuously heated according to half power, the temperature transmission of the upper part and the lower part of the liquid is balanced by reducing the heating efficiency, the temperature of the liquid can be more accurately controlled, and the condition of overflowing liquid caused by heating quickly is avoided.

Specifically, assuming that the full power of the heating assembly 20 is 800W under 220V ac, the voltage detection module 50 may detect the voltage of the ac in real time, and then the controller 30 may calculate the real-time full power of the heating assembly 20 according to the ratio between the real-time voltage and 220V. For example, if the real-time voltage of the alternating current is 230V, the real-time full power of the heating assembly 20 is about 836W. At this time, if the controller 30 uses 40 ac cycles, which is cycles of ac power, as the first adjustment cycle, and is usually 20ms (millisecond), the heating power of the heating element 20 when all the 40 ac cycles are heated is 836W, and if the stable power heating of 400W is to be realized, the controller 30 can calculate that there are about 19 ac cycles needing to be heated according to the proportional relationship between the heating power and the ac cycles. The controller 30 may equally distribute the 19 alternating current periods to the 40 alternating current periods included in the first adjustment period, that is, the controller 30 may determine that each heating time lasts for one alternating current period, and the interval time also lasts for one alternating current period, that is, the acquired time sequence is staggered by 19 heating times and 21 interval times. After receiving the time sequence, the heating assembly 20 heats the liquid contained in the vessel at the heating time indicated by the time sequence, and stops heating the liquid contained in the vessel at the interval time indicated by the time sequence.

Optionally, the controller 30 is further configured to obtain a first duty ratio of a first adjustment period according to the voltage of the alternating current, the alternating current period, and a preset heating power, and determine a second duty ratio of each of a plurality of second adjustment periods included in the first adjustment period according to the first duty ratio of the first adjustment period, where the second adjustment period includes a plurality of periods of the alternating current; and determining the time sequence according to a second duty cycle of a plurality of second adjustment periods included in a plurality of consecutive first adjustment periods.

Specifically, if the real-time voltage of the alternating current is 230V, the real-time full power of the heating element 201 is about 836W. If 40 ac cycles are taken as the adjustment cycles, the heating power of the heating element 201 during all heating in the 40 ac cycles is 836W, and if the preset heating power is 530W, that is, the heating power corresponding to the heating gear currently selected by the user is 530W, if heating with the stable power of 530W is required, the controller 30 may calculate, according to a proportional relationship between the heating power and the ac cycles, that is, the first duty ratio of the first adjustment cycle is 25/40, to obtain that the ac cycles required to be heated are about 25. In order to achieve uniform heating, the controller 30 needs to equally distribute the 25 ac cycles into 40 ac cycles included in the first adjustment cycle, and at this time, the controller 30 may set the second adjustment cycle, which includes 4 ac cycles, each of the first adjustment cycles including 10 second adjustment cycles. The controller 30 may then perform an averaging distribution according to the 10 second adjustment periods. For example, the controller 30 obtains an integer and a remainder of the number of ac cycles that need to be heated divided by the number of second adjustment cycles, that is, an integer 2 and a remainder 5 of 25 divided by 10, and then the controller 30 may first allocate two ac cycles that need to be heated for each second adjustment cycle, and then allocate the remaining 5 ac cycles that need to be heated to the first 5 second adjustment cycles, that is, as shown in fig. 2, the second duty ratio of the first 5 second adjustment cycles in the 10 second adjustment cycles is 3/4, the second duty ratio of the last 5 second adjustment cycles is 2/4, the ac cycle corresponding to the shaded portion in fig. 2 is the ac cycle that needs to be electrically heated by the heating assembly 20, and the non-shaded ac cycle is the ac cycle that does not need to be electrically heated by the heating assembly 20. As can be seen, the time series acquired by the controller 30 is the arrangement order of the 40 ac cycles satisfying the second duty ratio, and the ac cycle requiring heating corresponds to the heating time in the time series, and the ac cycle requiring no heating corresponds to the interval time in the time series.

In the technical scheme that this disclosed embodiment provided, can confirm heating element 20's heating time and interval time according to the voltage of alternating current in real time for this heating element 20 heats with the same power all the time, and then makes the speed of liquid intensification stable, has improved the culinary art effect, and user experience preferred.

In one embodiment, as shown in fig. 3, the heating assembly 20 includes a heating element 201, a switch control circuit 202, and a zero-crossing detection circuit 203.

Wherein, two ends of the heating element 201 are respectively connected with the live wire L and the zero wire N of the alternating current.

The input end of the zero-crossing detection circuit 203 is connected with the zero line, and the output end is connected with the controller 30; the zero-crossing detecting circuit 203 is configured to detect a zero-crossing signal of the alternating current and transmit the zero-crossing signal to the controller 30.

The controller 30 is configured to output the time sequence to the switch control circuit 202 according to the zero-crossing signal and the voltage of the alternating current.

The input end of the switch control circuit 202 is connected to the controller 30, and the output end is connected to the heating element 201; the switch control circuit 202 is used for connecting or disconnecting the heating element 201 and the zero line according to the sequence of the heating times, the interval times and the arrangement sequence between the heating times and the interval times, which are transmitted by the controller 30, so that the heating element 201 heats the liquid in the vessel with stable power.

For example, the heating element 201 may be a heating tube or an IH (Induction Heat) heating plate, and the heating element 201 may be connected to the live line and the neutral line of the alternating current, that is, the alternating current is used as the power source to Heat the liquid in the vessel.

The zero-crossing detecting circuit 203 may transmit the detected zero-crossing signal of the alternating current to the controller 30, and the controller 30 may control the heating time of the heating element 201 in time units of the alternating current period of the alternating current according to the zero-crossing signal of the alternating current.

Alternatively, it is assumed that the time sequence acquired by the controller 30 is as shown in fig. 2, that is, in each second adjustment period of the first five second adjustment periods, the controller 30 needs to control the heating element 201 to heat in the first 3 ac periods, and the heating element 201 stops heating in the next ac period; in each of the second adjustment periods of the last five second adjustment periods, the controller 30 needs to control the heating element 201 to heat in the first two ac periods, and the heating element 201 to stop heating in the last two ac periods. Since the zero-crossing detection circuit 203 can accurately detect the zero-crossing signal of the alternating current, the controller 30 can perform accurate time control, taking the first two second adjustment cycles as an example, the controller 30 can first control the switch control circuit 202 to connect the heating element 201 with the zero line N, then determine the cut-off point of the 3 rd alternating current cycle, control the switch control circuit 202 to disconnect the heating element 201 from the zero line N at the cut-off point of the 3 rd alternating current cycle, and then control the switch control circuit 202 to connect the heating element 201 with the zero line N at the cut-off point of the 4 th alternating current cycle, that is, the start point of the second adjustment cycle, after waiting for 1 alternating current cycle.

In one embodiment, as shown in fig. 4, the switch control circuit 202 includes a first resistor 2021, a second resistor 2022, a third resistor 2023, a fourth resistor 2024, a fifth resistor 2025, a first capacitor 2026, a second capacitor 2027, a third capacitor 2028, a first transistor 2029 and a thyristor 2120.

An input end a1 of the first resistor 2021 is connected to the controller 30, an output end a2 of the first resistor 2021 is connected to an input end B1 of the second resistor 2022, an output end B2 of the second resistor 2022 is grounded, an input end C1 of the first capacitor 2026 is connected to an output end a2 of the first resistor 2021, and an output end C2 of the first capacitor 2026 is connected to an output end B2 of the second resistor 2022; the output end a2 of the first resistor 2021 is connected to the base b of the first transistor 2029, the emitter E of the first transistor 2029 is grounded, the collector c of the first transistor 2029 is connected to the input end D1 of the third resistor 2023, the output end D2 of the third resistor 2023 is connected to the input end E1 of the fourth resistor 2024, and the output end E2 of the fourth resistor 2024 is connected to the neutral line N; the second capacitor 2027 is connected in parallel with the fourth resistor 2024; the output end D2 of the third resistor 2023 is connected to the control electrode G of the thyristor 2120, the first main electrode T1 of the thyristor 2120 is connected to the neutral line N, and the second main electrode T2 is connected to the heating element 201; the input terminal F1 of the fifth resistor 2025 is connected to the neutral line N, the output terminal F2 of the fifth resistor 2025 is connected to the input terminal H1 of the third capacitor 2028, and the output terminal H2 of the third capacitor 2028 is connected to the heating element 201.

For example, the thyristor 2120 is turned on when the control electrode G receives a high voltage, and the zero line of the alternating current is communicated with the heating element 201; when the control electrode G receives a low voltage or no voltage, it is switched off, in which case the zero line of the alternating current is disconnected from the heating element 201.

Therefore, when the heating element 201 needs to operate, the controller 30 may input a high voltage to the switch control circuit 202, that is, the input end of the first resistor 2021 may receive the high voltage output by the controller 30, that is, the voltage of the thyristor 2120 at the control electrode G may be pulled up, at this time, the thyristor 2021 is turned on, and the heating element 201 communicates with the zero line of the alternating current to start operating. When the heating element 201 needs to stop working, the controller 30 may disconnect the connection with the switch control circuit 202, that is, stop inputting a high voltage to the switch control circuit 202, at this time, no voltage is detected at the input end of the first resistor 2021, the voltage of the thyristor 2120 at the control electrode G is low, so that the thyristor 2021 is turned off, and the heating element 201 is disconnected from the zero line of the alternating current to stop working.

In one embodiment, as shown in fig. 5, the zero crossing detection circuit 203 includes a sixth resistor 2031, a seventh resistor 2032, an eighth resistor 2033, a ninth resistor 2034, a tenth resistor 2035, a second transistor 2036, a first diode 2037, and a fourth capacitor 2038.

For example, in the prior art, optical couples are generally used to implement zero-crossing detection, but the cost of the optical couples is high, and therefore the hardware cost of the whole zero-crossing detection circuit is high. This disclosure adopts the combination of second triode 2036 and first diode 2037 to realize zero cross detection, has reduced zero cross detection's cost, is favorable to the marketing of whole water yield detection module 10.

Specifically, assuming that the time sequence acquired by the controller 30 is shown in fig. 2, taking the first two second adjustment cycles as an example, the controller 30 may first input a high voltage to the switch control circuit 202, at which time the thyristor 2120 is turned on, the heating element 201 is communicated with the zero line N, and the heating element 201 starts to heat. Then the controller 30 detects the zero crossing point of the alternating current through the zero-crossing detection circuit 203, that is, accurately determines the cut-off point of the 3 rd alternating current period, and stops inputting the high voltage to the switch control circuit 202 before the cut-off point after the half period of the 3 rd alternating current period, based on the characteristics of the thyristor 2120, the thyristor 2120 can be cut off at the cut-off point of the 3 rd alternating current period, at this time, the heating element 201 is disconnected from the zero line N, and the heating element 201 stops heating; after 1 ac cycle, high voltage is input to the switch control circuit 202 again before the cut-off point after the half cycle of the 4 th ac cycle, at this time, the thyristor 2120 may be turned on at the cut-off point of the 4 th ac cycle, the heating element 201 is communicated with the neutral line N, and the heating element 201 starts heating again. By analogy with the time sequence shown in fig. 2, the heating time of the heating element 201 can be finely controlled, and the heating power of the heating element 201 is stabilized.
