In a first aspect, referring to fig. 1, a refrigeration control method according to an embodiment of the present application includes:

s101, determining the opening state of the integrated cooker and the opening state of the refrigeration module;

s102, acquiring the current moment;

s103, determining the working period of the current moment;

s104, determining a refrigeration mode according to the working period, and controlling the refrigeration module to operate according to the refrigeration mode;

wherein the operation period includes a low noise operation period, and the cooling mode includes a first operation mode corresponding to the low noise operation period.

In the process of performing refrigeration control on an integrated cooker product, the starting state of the integrated cooker and the starting state of a refrigeration module need to be determined at first. Specifically, the integrated stove can be started according to an integrated stove starting instruction, and a main motor of the integrated stove is controlled to run at a first air speed so as to purify oil smoke in the air. And meanwhile, the refrigeration module is started according to the starting instruction of the refrigeration module. Through opening of the integrated kitchen of control and refrigeration module, refrigerate through refrigeration module in integrated kitchen is working, can improve current ambient temperature. Further, the current time is acquired. The current time is a certain time value defined as a 24-hour time. For example, the current time is 10 hours and 30 minutes. The 24 hours are divided into a plurality of working periods by presetting one or more time values, so that the working period of the current time is determined. For example, a first time and a second time are preset, and if the current time is earlier than the first time or later than the second time, the current time is determined to be in a low-noise working period; and if the current time is between the first time and the second time, determining that the current time is in a non-low-noise working period. And if the current time is in a low-noise working period and the working noise of the integrated cooker needs to be reduced, controlling the refrigeration module to work in a low-noise mode, so that each device in the refrigeration module runs at a lower working rotating speed or working frequency. And if the current time is in a non-low-noise working period, controlling the refrigeration module to work in a normal mode, so that each device in the refrigeration module works normally, and ensuring the working efficiency. By the control method, the use performance of the integrated cooker product can be better improved, the noise generated by the integrated cooker product during working is reduced, and the applicability of the integrated cooker product is improved.

In some embodiments, to improve data accuracy, the current time may also be acquired at a first time interval. The first time interval is generally any time value within 0 to 10 minutes, and is not limited. The first time interval may be a default time value set by the product when the product leaves the factory, or may be a time value set by the user according to the actual demand. For example, the first time interval may be 2 minutes or 5 minutes. When the first time interval is set to be 2 minutes, the current time is obtained every 2 minutes, and the working time interval of the current time is determined, so that the refrigeration module is controlled to operate in different refrigeration modes according to different working time intervals, and the noise generated by the integrated cooker product during working is reduced. Data accuracy can be improved by acquiring the current time at the first time interval, so that control accuracy is improved, and usability of the integrated cooker product can be better improved.

Referring to fig. 2, in some embodiments, step S103 includes:

s201, if the current time is earlier than the first time or later than the second time, determining that the current time is in a low-noise working period;

s202, if the current time is between the first time and the second time, determining that the current time is in a non-low-noise working period;

the first time and the second time are within the same day, and the first time is earlier than the second time.

In order to improve the control accuracy, the current time is acquired after the integrated cooker and the refrigeration module are determined to be in the open state. The non-low-noise working period and the low-noise working period are divided by one or more preset time values. The preset time value is a time made of 24 hours. Specifically, the 24 hours are divided into three time intervals by the first time, the second time, and the third time. The first time point is 6 points, the second time point is 20 points, and the third time point is 24 points (also 0 points). The 24 hours are divided into 0 to 6, 6 to 20, and 20 to 24 hours by the first, second, and third times. Wherein the night time period comprises 0 to 6 points and 20 to 24 points. The daytime period includes 6 o 'clock to 20 o' clock. When the current time is earlier than 6 o 'clock or later than 20 o' clock, it indicates that it is a night period. At night, the working noise of the integrated cooker product is reduced, the current time is determined to be in a low-noise working period, and the refrigeration module is controlled to operate at a small refrigeration power to avoid generating large noise. And when the current time is between 6 and 20 points, indicating that the time is a daytime period, determining that the current time is in a non-low-noise working period, and determining and controlling the refrigeration module to operate at normal refrigeration power. The working time intervals can be conveniently divided through the first moment, the second moment and the third moment, and the control efficiency is improved.

In some embodiments, the first time is a threshold between early morning and morning, and the first time is between 3 and 12 hours. The second time is a limit value between afternoon and late night, and the second time is between 14 and 24 o' clock. The third time is a fixed time (0 o 'clock or 24 o' clock). The first time, the second time, and the third time may be set according to actual conditions, but are not limited thereto.

In some other specific embodiments, to avoid that the integrated cooktop product generates a large noise during the midday period, the fourth and fifth moments are introduced on the basis of the first, second and third moments. The first time, the second time, the third time, the fourth time and the fifth time are on the same day, the fourth time and the fifth time are between the first time and the second time, and the fourth time is earlier than the fifth time. The 24 hours are divided into five time periods by the first time, the second time, the third time, the fourth time and the fifth time. The first time point is 5 points, the second time point is 22 points, the third time point is 24 points (also 0 points), the fourth time point is 12 points, and the fifth time point is 14 points. The night time period includes 0 o 'clock to 5 o' clock, 12 o 'clock to 14 o' clock, and 22 o 'clock to 24 o' clock. The noon break period includes 12 o 'clock to 14 o' clock. The daytime period includes 5 o 'clock to 12 o' clock, 14 o 'clock to 22 o' clock. When the current time is between 0 and 5 o ' clock or between 12 and 14 o ' clock or between 22 and 24 o ' clock, indicating that it is a night time period, it is necessary to reduce the operating noise of the integrated cooker product. And when the current time is between 12 o 'clock and 14 o' clock, which indicates that the noon break period is the time, the operation noise of the integrated cooker product also needs to be reduced. And when the current time is in the night time period or the noon break period, determining and controlling the refrigeration module to operate in a refrigeration mode with lower refrigeration power. The working noise of the refrigeration module is reduced by reducing the running wind speed of the refrigeration fan and the running frequency of the compressor, so that the noise reduction control of the integrated kitchen range product is realized.

Referring to fig. 3, in some embodiments, step S104, comprises:

s301, if the current time is in a low-noise working period, determining and controlling the refrigeration module to work in a first working mode;

s302, if the current time is in a non-low-noise working period, determining and controlling the refrigeration module to work in a second working mode;

and the refrigerating power of the first working mode is smaller than that of the second working mode.

In order to reduce the operating noise of the integrated cooker product, the current time is acquired after it is determined that the integrated cooker and the cooling module are in an open state. The low-noise working period and the non-low-noise working period are divided by one or more preset time values.

Specifically, the first time is 8 o 'clock, the second time is 22 o' clock, the third time is a fixed time (0 o 'clock or 24 o' clock), and 24 hours are divided into 0 o 'clock to 8 o' clock, 8 o 'clock to 22 o' clock, and 22 o 'clock to 24 o' clock by the first time, the second time, and the third time. The night period includes 0 o 'clock to 8 o' clock, 88 o 'clock to 24 o' clock. The daytime period includes 8 o 'clock to 88 o' clock.

When the current time is earlier than 8 o 'clock or later than 22 o' clock, it indicates that it is a night period. In the night time period, the working noise of the integrated cooker product should be reduced, and the cooling mode is the first working mode when the current time is in the low-noise working time period. And in the first working mode, the refrigerating fan and the compressor in the refrigerating module are controlled to operate at smaller working parameters, so that the generated working noise is smaller.

And if the current time is between 8 and 88 points, which indicates that the current time is a daytime period, and the current time is in a non-low-noise working period, determining that the refrigeration mode is the second working mode. And under the second working mode, the normal operation of all equipment in the refrigeration module is controlled, and the refrigeration effect is better. The method can adjust the refrigeration module to operate in different refrigeration modes according to different working periods, so that the refrigeration module operates at a lower refrigeration frequency in a low-noise working period to generate lower working noise, and the use performance of the integrated cooker product can be better improved.

Referring to fig. 4, in some embodiments, the refrigeration module includes a compressor and a refrigeration fan, and the step S104 includes:

s401, if the current time is in a low-noise working period, determining and controlling a refrigeration fan to operate at a first rotating speed and a compressor to operate at a first frequency;

s402, if the current time is in a non-low-noise working period, determining and controlling the refrigeration fan to operate at a second rotating speed and the compressor to operate at a second frequency;

the first rotating speed is less than the second rotating speed, and the first frequency is less than the second frequency.

And acquiring the current moment after determining that the integrated cooker and the refrigeration module are in the opening state. The working period of the integrated cooker is divided into a non-low noise working period and a low noise working period by a first time and a second time.

For example, the current time is earlier than the first time or later than the second time, the current time is determined to be in a low-noise working period, and the noise reduction control is performed on the refrigeration module. Specifically, the low-speed operation or the medium-speed operation of the refrigeration fan and the low-frequency operation or the medium-frequency operation of the compressor are controlled. Through the medium-low speed operation of the refrigerating fan and the medium-low frequency operation of the compressor, the working noise of the refrigerating module can be effectively reduced while normal refrigeration is ensured.

And when the current moment is between the first moment and the second moment, determining that the current moment is in a non-low-noise working period, and determining and controlling the refrigeration module to keep normal operation. In order to improve the refrigeration rate, when the current time is not in the low-noise working period, the refrigeration fan is controlled to operate at a high speed, and the compressor operates at a high frequency. The high-speed operation of the refrigerating fan and the high-frequency operation of the compressor can realize quick refrigeration, and the environment temperature is well improved.

It should be noted that, a commonly used refrigeration fan is an ac motor. The working speed of the refrigerating fan is generally divided into three levels of high speed, medium speed and low speed. Each gear corresponds to different rotating speed range values of the refrigerating fan. The specific numerical value of the working speed of the refrigerating fan can be determined according to the specific model and the actual requirement of the refrigerating fan. The working frequency of a common compressor is generally divided into three levels, namely a high frequency level, a medium frequency level and a low frequency level. Wherein, when the working frequency of the compressor is 50Hz or above, the high-frequency operation is adopted. When the working frequency of the compressor is between 30Hz and 50Hz, the operation is in a medium frequency. When the working frequency of the compressor is 30Hz or below, the operation is low frequency. The specific value of the operating frequency of the compressor is adjustable according to the specific model of the compressor and the actual requirement, and is not fixed and constant.

Referring to fig. 5, in some embodiments, step S104 includes:

s501, if the current moment is in a low-noise working period, acquiring a current value of a main fan of the integrated stove at a preset time interval;

s502, if the current value is larger than a first preset threshold value, reducing the running wind speed of the main fan;

and S503, if the current value is less than or equal to the first preset threshold value, controlling the running wind speed of the main fan to be kept unchanged.

In order to further reduce the working noise of the refrigeration module, after the integrated cooker and the refrigeration module are determined to be in an open state and the current moment is obtained and determined to be in a low-noise working period, the current value of the main fan of the integrated cooker is obtained at a preset time interval. The main fan is a main fan on a range hood of the integrated cooker. According to the magnitude relation between the current value I and the first preset threshold value I1, the running wind speed of the main fan can be determined. For example, the operating wind speed of the main fan includes three types, i.e., high speed, low speed, and medium speed. The noise generated when the main fan operates at different operating wind speeds is different in magnitude.

If I is larger than I1, the operation wind speed of the main fan is larger, the generated operation noise is larger, and the operation wind speed of the main fan is reduced. The operating noise of the integrated kitchen product is further reduced by reducing the operating wind speed of the main fan.

If I is less than or equal to I1, the working noise generated by the operation of the main fan is moderate. In order to ensure the effective purification of the oil fume, the operation wind speed of the main fan is kept unchanged. It should be noted that, in order to ensure the refrigeration efficiency, when I ≦ I1, the operating wind speed of the refrigeration fan and the operating frequency of the compressor are kept unchanged. The working noise of the integrated stove product can be further reduced by adjusting the running air speed of the main fan at the low-noise working time period at the current moment, so that the use performance of the integrated stove product is improved.

In some embodiments, the first time is 6 o 'clock, the second time is 20 o' clock, the third time is 0 o 'clock or 24 o' clock, the predetermined time is 5 minutes, and the first predetermined threshold I1 is 10A. The 24 hours are divided into 0 to 6, 6 to 20, and 20 to 24 hours by the first, second, and third times. The night period includes 0 o 'clock to 6 o' clock, 20 o 'clock to 24 o' clock. The daytime period includes 6 o 'clock to 20 o' clock. When the current time is earlier than 6 o 'clock or later than 20 o' clock, it indicates that it is a night period. During the night time, the working noise of the integrated cooker product should be reduced, and it is determined that the current time is in the low noise working time period. And controlling the low-speed operation or the medium-speed operation of the refrigeration fan and the low-frequency operation or the medium-frequency operation of the compressor at the current moment. The normal refrigeration can be ensured and the working noise of the refrigeration module can be effectively reduced through the medium-low speed operation of the refrigerating fan and the medium-low frequency operation of the compressor.

To further reduce noise, the main fan current value is taken every 5 minutes. If I is larger than 10A, the operation wind speed of the main fan is larger, the generated working noise is larger, and the operation wind speed of the main fan is reduced. The working noise of the integrated kitchen range product is further reduced by reducing the running air speed of the main fan. If I is less than or equal to 10A, the working noise generated by the operation of the main fan is moderate. In order to ensure the effective purification of the oil fume, the operation wind speed of the main fan is kept unchanged. In the low-noise working period, the compressor, the main fan and the refrigerating fan are controlled to operate with smaller working parameters, so that smaller working noise is generated, and the use performance of the integrated stove product can be better improved.

When the current time is between 6 and 20 points, the daytime period is indicated, the current time is determined to be in the non-low noise working period, the refrigeration fan is controlled to operate at a high speed, and the compressor operates at a high frequency. The high-speed operation of the refrigerating fan and the high-frequency operation of the compressor can realize quick refrigeration, and the environment temperature is well improved. The method can adjust the refrigeration module to operate in different refrigeration modes according to different working periods, and improves the applicability of the integrated cooker product.

The first preset threshold may be a default current value set when the product is shipped, or may be a current value set by the user according to actual needs. In some embodiments, the first predetermined threshold is used as a current limit value of the main fan, and may be a value between 0 and 20A. In other embodiments, the first preset threshold may be a value in other value ranges, but is not limited thereto.

The current value of the main fan can be a current value obtained at the current moment; or in a certain time period at intervals, the current value obtained in real time is averaged, and the average value is taken as the current value of the main fan; in this case, the current value of the main fan may be set to a value equal to or greater than a predetermined value.

Referring to fig. 6, in some embodiments, step S104 includes:

s601, if the current time is in a low-noise working period, acquiring a voltage value of a main fan of the integrated cooker at preset time intervals;

s602, if the voltage value is larger than a second preset threshold value, reducing the running wind speed of the main fan;

and S603, if the voltage value is less than or equal to a second preset threshold value, controlling the running wind speed of the main fan to be kept unchanged.

In order to further reduce the working noise of the refrigeration module, after the integrated cooker and the refrigeration module are determined to be in an open state and the current time is in a low-noise working period, the voltage value of a main fan of the integrated cooker is obtained at a preset time interval. The main fan is a main fan on a range hood of the integrated cooker. According to the magnitude relation between the voltage value U and the second preset threshold value U1, the running wind speed of the main fan can be determined. For example, the main fan has three operating wind speeds, i.e., a high speed, a low speed, and a medium speed, and noise generated when the main fan operates at different operating wind speeds is different in magnitude.

When U is larger than U1, the running wind speed of the main fan is larger, the generated working noise is larger, and the running wind speed of the main fan is reduced. The operating noise of the integrated kitchen product is further reduced by reducing the operating wind speed of the main fan.

When U is less than or equal to U1, the working noise generated by the operation of the main fan is moderate. In order to ensure the effective purification of the oil fume, the operation wind speed of the main fan is kept unchanged. It should be noted that, in order to ensure the cooling efficiency, when U is less than or equal to U1, the operating wind speed of the cooling fan and the operating frequency of the compressor are kept unchanged. Through being in the adjustment of low noise working interval to main fan operation wind speed at present moment, can further reduce the operating noise of integrated kitchen product to improve the performance of integrated kitchen product.

The voltage value of the main fan can be a voltage value obtained at the current moment; or in a certain time interval, the voltage value obtained in real time is averaged, and the average value is taken as the voltage value of the main fan; in this case, the voltage value of the main fan may be set to be equal to or greater than a predetermined value.

In addition, the preset time is generally any time value within 0 to 10 minutes, and is not limited. The preset time can be a default time value set when the product leaves a factory, or a time value set by a user according to actual requirements. For example, the preset time may be 5 minutes or 8 minutes. When the preset time is 5 minutes, the current value or the voltage value is obtained every 5 minutes. And adjusting the running air speed of the main fan according to the current value or the voltage value to realize the noise reduction control of the integrated stove product. The data accuracy can be improved by acquiring the current value or the voltage value in preset time, so that the accuracy of refrigeration control on the integrated cooker product is improved, and the use performance of the integrated cooker product can be better improved.

In some embodiments, after determining the cooling mode according to the operation period and controlling the operation of the cooling module according to the cooling mode, the cooling control method further includes:

controlling the refrigeration module to be closed in response to a closing instruction; wherein, the closing instruction comprises at least one of a closing instruction of the refrigeration module and a closing instruction of the integrated cooker.

In order to reduce energy consumption, the refrigeration module can be controlled to operate for a period of time, then a closing instruction is obtained, and the refrigeration module is closed according to the closing instruction. For example, when the desired cooling effect is achieved and the integrated cooker stops working, the integrated cooker and the cooling module are directly turned off according to the integrated cooker turn-off instruction. When the expected refrigerating effect is achieved and the opening state of the integrated cooker still needs to be kept, the refrigerating module is closed according to the closing instruction of the refrigerating module, and other parts of the integrated cooker still keep the opening state.

Further, if there is no responsive shutdown command (no shutdown command is obtained), the refrigeration module is kept on. And acquiring the current time at a second time interval, and determining the working period of the current time. The cooling mode is changed according to the operation period. And continuously acquiring a closing instruction until the closing instruction is acquired, and controlling the refrigeration module to close in response to the closing instruction. The closing instruction is used for controlling the refrigeration module to be closed, so that the use performance of the integrated kitchen range product can be effectively improved, the refrigeration module can be closed in time, the energy consumption is reduced, and the energy-saving effect is achieved.

In addition, after the refrigeration module is turned on through step S101, both the compressor and the refrigeration fan in the refrigeration module operate at initial operation parameters. And when the compressor and the refrigerating fan work with initial operation parameters, acquiring the current moment. And determining the refrigeration mode by determining the working period of the current moment, and controlling the refrigeration module to operate in different refrigeration modes. After the refrigeration module is turned on, the refrigeration fan is operated with the automatic wind. Specifically, when the refrigeration fan is in an automatic air state, the current ambient temperature is acquired. According to the difference between the current environment temperature and the set temperature, the rotating speed of the refrigerating fan can be automatically selected to be high speed, medium speed or low speed. Correspondingly, the cooling fan may generate high wind, medium wind, or low wind. If the current running wind speed of the refrigeration fan is low wind, the difference between the current environment temperature and the set temperature t exceeds a first temperature value (if the current environment temperature is higher than the set temperature, and the difference between the current environment temperature and the set temperature exceeds 1 ℃), adjusting the running wind speed of the refrigeration fan to be medium wind, namely adjusting the working rotating speed of the refrigeration fan from low speed to medium speed. If the current running wind speed of the refrigeration fan is low wind, the difference between the current environment temperature and the set temperature exceeds a second temperature value (if the current environment temperature is higher than the set temperature, and the difference between the current environment temperature and the set temperature exceeds 2 ℃), the running wind speed of the refrigeration fan is adjusted to high wind, namely the working rotating speed of the refrigeration fan is adjusted from low speed to high speed. And if the current running wind speed of the refrigerating fan is a wind stroke, the running wind speed of the refrigerating fan is adjusted at least after 1 minute interval. Specifically, if the difference between the current ambient temperature and the set temperature exceeds a first temperature value, the operating wind speed of the refrigeration fan is adjusted to high wind, that is, the operating rotating speed of the refrigeration fan is adjusted from a medium speed to a high speed. If the difference between the current environment temperature and the set temperature exceeds a third temperature value (if the current environment temperature is lower than the set temperature and the difference between the current environment temperature and the set temperature exceeds-1 ℃), adjusting the running wind speed of the refrigeration fan to low wind, namely adjusting the working rotating speed of the refrigeration fan from medium speed to low speed. And if the current running wind speed of the refrigeration fan is high wind, the running wind speed of the refrigeration fan is adjusted at least after 1 minute. Specifically, if the current ambient temperature is not greater than the set temperature, the operating air speed of the refrigeration fan is adjusted to be a medium wind speed, that is, the operating speed of the refrigeration fan is adjusted from a high speed to a medium speed. If the difference between the current environment temperature and the set temperature exceeds a third temperature value (if the current environment temperature is lower than the set temperature and the difference between the current environment temperature and the set temperature exceeds-1 ℃), adjusting the working rotating speed of the refrigerating fan from high speed to low speed, thereby adjusting the running wind speed of the refrigerating fan to low wind.

Similarly, after the refrigeration module is started in step S101, the current ambient temperature is obtained, and if the difference between the current ambient temperature and the set temperature exceeds the first temperature value (if the current ambient temperature is higher than the set temperature, the difference between the current ambient temperature and the set temperature exceeds 1 ℃), the compressor is controlled to start after the cooling fan operates for at least a preset time (e.g., 15 seconds). In addition, the compressor also needs to meet the shutdown protection for a preset time, and the compressor needs to meet the shutdown protection for 3 minutes. And after the compressor is started, if the current ambient temperature is lower than the set temperature, controlling the compressor to be closed. It should be noted that the compressor can be controlled to start or stop according to the magnitude relationship between the current ambient temperature and the preset temperature after the compressor is started and after the preset running time elapses. The preset running time can be set according to actual conditions. For example, the preset operation time is 300 seconds to 310 seconds. When the preset temperature is adjusted, the start and stop of the compressor are required to be controlled immediately according to the size relation between the current environment temperature and the preset temperature, the use safety of the compressor can be guaranteed, and the service life of the compressor can be prolonged. In addition, when the refrigeration module is controlled to be closed, the compressor needs to be controlled to be closed first, and the refrigeration fan is closed after the preset closing time is delayed. The preset closing time can be 5 seconds, namely when the refrigeration module is controlled to be closed, the compressor is controlled to be closed firstly, and the refrigeration fan is closed after the compressor is closed for 5 seconds, so that the compressor and the refrigeration fan can be effectively protected, the stability of the whole system is improved, and the service life of each device is prolonged.

Further, the time obtaining module 720 obtains the current time. The current time is a certain time value made by 24 hours, for example, 10 hours and 30 minutes. The working period judging module 730 determines the working period of the current time by presetting one or more time points and dividing the 24 hours into a plurality of working periods. For example, a first time and a second time are preset, and if the current time is earlier than the first time or later than the second time, the current time is determined to be in a low-noise working period; and if the current time is between the first time and the second time, determining that the current time is in the non-low-noise working period. . If the current time is in the low-noise working period and the working noise of the integrated cooker needs to be reduced, the control module 740 controls the refrigeration module to work in the low-noise mode, so that each device in the refrigeration module runs at a lower working speed or working frequency. If the current time is in the non-low noise working period, the control module 740 determines and controls the refrigeration module to work in the normal mode, so that each device in the refrigeration module works normally, and the working efficiency is ensured. By the method, the use performance of the integrated cooker product can be better improved, the noise generated by the integrated cooker product during working is reduced, and the applicability of the integrated cooker product is improved.
