As shown in fig. 1 to 3, the present invention provides a temperature control method 300 of a refrigerator bar, comprising:
detecting an actual ambient temperature outside the bar counter;
comparing the actual ambient temperature with a preset ambient temperature;
and if the actual ambient temperature is less than the preset ambient temperature, stopping supplying power to the temperature control system of the refrigerator bar counter.
As shown in fig. 2, the temperature control system 200 includes an air blowing device 210 and a heating device 220, and the air blowing device communicates with a storage space (not shown) inside the bar 130 and a refrigerating or freezing compartment (not shown) inside the refrigerator 100.
In this embodiment, if the actual ambient temperature is less than the preset ambient temperature, the power supply to the air supply device 210 and the heating device 220 is stopped, i.e. the main energy dissipation elements in the temperature control system 200 in the bar 130 are turned off, so as to achieve the purpose of energy saving.
As shown in fig. 1 and 2, the temperature control system 200 is disposed in the storage space inside the bar 130, the air supply device 210 is, for example, a fan, which communicates the storage space with the refrigerating or freezing compartment of the refrigerator 100, and the air supply device 210 rotates to guide the cold energy in the refrigerating or freezing compartment to be transferred toward the storage space, so as to reduce the temperature in the storage space; the heating device 220 is, for example, a heating wire, which is disposed at the outside or inside of the inner wall of the bar counter, the shape of the inner wall defines the storage space, and the heating wire is activated to supply heat to raise the temperature in the storage space.
In addition, the temperature control system 200 further includes a first temperature sensor 230 disposed outside the bar 130 for detecting an actual ambient temperature.
The first temperature sensor 230 detects that the actual ambient temperature is conducted to the main control board 260, and the main control board 260 may be a control chip of the refrigerator 100 itself, wherein the main control board 260 includes a processing unit and a storage unit, the storage unit stores a preset ambient temperature, and the processing unit receives the actual ambient temperature and reads the preset ambient temperature, and completes the comparison between the actual ambient temperature and the preset ambient temperature, and outputs a control instruction according to the comparison result.
If the actual ambient temperature is less than the preset ambient temperature, which indicates that the ambient temperature is low, at this time, even if the bar door of the bar 130 is frequently opened or closed, the actual working temperature in the storage space will not change obviously, and then a control instruction for stopping power supply to the air supply device 210 and the heating device 220 is output, so that the bar 130 enters an energy-saving state, and the purpose of energy saving is achieved.
If the actual ambient temperature is greater than the preset ambient temperature, which indicates that the ambient temperature is higher, at this time, the bar door of the bar 130 is frequently opened and closed, which easily causes an obvious change in the actual operating temperature in the storage space, so that the temperature control system 200 corresponding to the bar 130 operates according to the actual operating temperature in the bar 130 and the difference between the preset operating temperatures, thereby avoiding an increase in energy consumption.
As shown in fig. 3, according to the difference between the actual operating temperature and the preset operating temperature, the specific process of operating the temperature control system 200 of the corresponding control bar 130 includes:
detecting the actual working temperature in the bar counter;
calculating a difference between the actual working temperature and a preset working temperature;
comparing the difference between the actual working temperature and the preset working temperature with a preset difference;
if the difference between the actual operating temperature and the preset operating temperature is less than the preset difference, the heating device 220 is started; if the difference between the actual operating temperature and the preset operating temperature is greater than the preset difference, the blower 210 is started.
In a preferred embodiment, if the difference between the actual operating temperature and the preset operating temperature is equal to the preset difference, the power supply to the heating device 220 and the air supply device 210 is stopped, and the energy saving state is entered.
In this embodiment, the actual working temperature inside the bar 130 is detected by the second temperature sensor 240 of the temperature control system 200, i.e. the second temperature sensor 240 is disposed in the storage space inside the bar 130.
In addition, the preset difference is stored in the storage unit of the main control board 260 in advance.
As shown in fig. 3, by periodically detecting the actual working temperature, the difference between the actual working temperature and the preset working temperature is controlled to be equal to the preset difference, so as to establish a constant-temperature storage space, thereby realizing better storage experience.
Specifically, the temperature control system 200 further includes a timing unit 250 for starting timing when detecting an actual operating temperature inside the bar counter when detecting that the actual ambient temperature is greater than the preset ambient temperature; the actual operating temperature inside the bar counter is re-detected every time the accumulated timer reaches a predetermined time period.
In other words, the main control board 260 determines that the actual ambient temperature is greater than the preset ambient temperature, and outputs the detection signal to the second temperature sensor 240 and the timing signal to the timing unit 250, where the second temperature sensor 240 starts to detect the actual operating temperature inside the bar 130, and the timing unit 250 starts to perform timing. When the timing unit 250 operates for a predetermined period of time, it feeds back a timing completion signal to the main control board 260, and the main control board 260 repeatedly outputs a detection signal to the second temperature sensor 240 and a timing signal to the timing unit 250, and the second temperature sensor 240 re-measures the actual working temperature in the storage space; and the timing unit 250 restarts the timing to repeat the detection and timing process, and adjusts the actual operating temperature by the cooling power supplied from the air supply device 210 or the heating power supplied from the heating device 220 for a predetermined period of time, so as to achieve that the difference between the actual operating temperature and the preset operating temperature is equal to the preset difference.
It should be noted that, if the difference between the actual working temperature and the preset working temperature is equal to the preset difference in the current predetermined time period, after the current predetermined time period is finished, the main control board 260 continues to output the detection signal to the second temperature sensor 240 and the timing signal to the timing unit 250, so as to realize real-time monitoring of the actual working temperature in the storage space in the bar 130, and ensure that the temperature in the storage space is relatively constant.
In a preferred embodiment, the difference between the actual operating temperature and the preset operating temperature is preferably 0.
In a preferred embodiment, a predetermined time period may be set by itself according to actual needs.
In addition, the step of detecting the actual ambient temperature outside the bar counter specifically includes:
identifying a current control mode, wherein the control mode comprises a storage mode, an intelligent mode and a quick cooling mode;
and detecting the actual environment temperature outside the bar counter when the current control mode is identified as the storage mode.
That is, the main control board 260 receives control modes including a storage mode, an intelligent mode, and a rapid cooling mode; when the control mode is judged to be the storage mode, the actual ambient temperature outside the bar 130 is preferentially detected.
In a preferred embodiment, the control mode may be input to the main control board of the refrigerator 100 through the cloud with a communication function, or may be directly input to the control panel on the door body 110 of the refrigerator 100, and recognized by the main control board of the refrigerator 100; or, the application program input on the intelligent terminal carried by the user is identified by the main control board of the refrigerator 100 through the data communication between the intelligent terminal and the refrigerator.
It should be noted that, when the control mode is multiple, the main control board executes the steps in the temperature control method under different control modes according to different control modes, so as to realize multi-scene application of the temperature control system of the bar counter, so as to adapt to different use requirements of users.
As shown in FIG. 4, another control mode, such as a smart mode temperature control method 400 is also provided in another embodiment of the present invention.
As shown in fig. 1, 2 and 4, in the smart mode, the temperature control method 400 of the bar 130 includes:
identifying a category of items placed in the storage space of the bar 130;
acquiring a storage temperature corresponding to the category of the article;
detecting an actual operating temperature of the storage space of the bar 130;
calculating a difference between the actual operating temperature and the storage temperature; and
if the difference between the actual working temperature and the stored temperature is greater than the preset difference, the air supply device 210 in the temperature control system 200 of the bar 130 is started; if the difference between the actual operating temperature and the stored temperature is less than the preset difference, the heating device 220 of the temperature control system 200 of the bar 130 is provided.
Specifically, when the main control board 260 recognizes that the current control mode is the smart mode, a category of the article to be placed in the storage space is recognized, wherein the category of the article includes, for example, fruits, dairy products, cosmetics, pharmaceutical preparations, and the like.
In a preferred embodiment, the step of identifying the category of the item placed in the storage space of the bar counter further comprises: the category of the articles placed in the storage space is marked in advance. In the present invention, a user selects the name of an item to be placed in the storage space through an application program on the intelligent terminal or a control panel on the door body 110 of the refrigerator 100, and after the main control panel 260 obtains the name of the item, the corresponding category is marked according to the name of the item.
In other embodiments of the present invention, the category label of the article may also be a label that is directly selected by an application program on the intelligent terminal or a control panel on a door body of the refrigerator, where the main control panel directly identifies the category of the article placed in the storage space.
When the main control board 260 recognizes the category of the article, the acquired category is compared with the category in the comparison table stored in the storage unit in advance, the category consistent with the comparison table and the corresponding storage temperature thereof are acquired, and the corresponding storage temperature is used as the optimal storage temperature of the category of the current article.
The main control board 260 continues to output the detection signal to the second temperature sensor 240, and the second temperature sensor 240 is configured to detect an actual working temperature of the storage space and feed back the detected actual working temperature to the main control board 260.
After the main control board 260 obtains the actual working temperature, reads the corresponding storage temperature, calculates the difference between the actual working temperature and the storage temperature, compares the difference between the actual working temperature and the storage temperature with a preset difference, and controls the air supply device 210 and the heating device 220 in the temperature control system 200 to work so that the difference between the actual working temperature and the storage temperature is equal to the preset difference, and further the actual working temperature and the storage temperature are the same.
If the difference between the actual working temperature and the storage temperature is greater than the preset difference, which means that the actual working temperature is greater than the storage temperature, the air supply device 210 is started, which guides the cold in the refrigerating or freezing compartment of the refrigerator 100 to be transferred toward the storage space, so as to reduce the temperature in the storage space; if the difference between the actual operating temperature and the storage temperature is smaller than the preset difference, which means that the actual operating temperature is smaller than the storage temperature, the heating device 220 is started to provide heat to the storage space so as to raise the temperature in the storage space.
In addition, if the difference between the actual working temperature and the storage temperature is equal to the preset difference, it means that the actual working temperature is equal to the storage temperature, at this time, the power supply to the air supply device 210 and the heating device 220 may be stopped, so as to achieve the purpose of energy saving.
As shown in fig. 4, the step of obtaining the storage temperature corresponding to the category of the article further includes:
the set rotational speed of the blower 210 corresponding to the type of the article and the set heating rate of the heater 220 corresponding to the type of the article are obtained.
If the difference between the actual working temperature and the storage temperature is greater than the preset difference, which means that the actual working temperature is greater than the storage temperature, the air supply device 210 operates according to the set rotation speed; if the difference between the actual operating temperature and the storage temperature is less than the preset difference, which means that the actual operating temperature is less than the storage temperature, the heating device 220 is operated at the set heating rate.
By adapting the set rotational speed of the air supply device 210 and the set heating rate of the heating device 220 to the type of the article, it is ensured that the temperature is reduced or increased without affecting the article to be stored in the process of adjusting the actual working temperature to be consistent with the storage temperature. Taking vegetables and fruits as the object types as examples, the low-speed rotation of the air supply device 210 in the cooling process can avoid the problem that the high-speed rotation of the air supply device 210 causes too fast water flow velocity in the vegetables and fruits to cause fresh-keeping failure.
In this embodiment, the set rotational speed of the blower 210 and the set heating rate of the heating device 220 are stored in the aforementioned lookup table in advance, and are in one-to-one correspondence with the types of the articles, that is, one type of the articles corresponds to one storage temperature, one set rotational speed, and one set heating rate.
In addition, as shown in fig. 4, the step of detecting the actual operating temperature of the storage space inside the bar 130 specifically includes:
when detecting the actual working temperature of the storage space in the bar 130, starting timing; wherein the actual operating temperature of the storage space inside the bar 130 is re-detected every time the accumulated time reaches a predetermined time period.
By periodically detecting the actual working temperature, the difference between the actual working temperature and the storage temperature is controlled to be equal to a preset difference, for example, 0. When the difference between the actual working temperature and the storage temperature is 0, the articles in the storage space can be kept in the optimal temperature environment.
Specifically, the main control board 260 outputs a detection signal to the second temperature sensor 240 and a timing signal to the timing unit 250, the second temperature sensor 240 starts to detect the actual operating temperature inside the bar 130, and the timing unit 250 starts to time. When the timing unit 250 operates for a predetermined period of time, it feeds back a timing completion signal to the main control board 260, and the main control board 260 repeatedly outputs a detection signal to the second temperature sensor 240 and a timing signal to the timing unit 250, and the second temperature sensor 240 re-measures the actual working temperature in the storage space; and the timing unit 250 restarts the timing to repeat the detection and timing process, and adjusts the actual operating temperature by the cooling power supplied from the air supply device 210 or the heating power supplied from the heating device 220 for a predetermined period of time, so that the difference between the actual operating temperature and the storage temperature is equal to the preset difference.
It should be noted that, if the difference between the actual working temperature and the preset working temperature is equal to the preset difference in the current predetermined time period, after the current predetermined time period is finished, the main control board 260 continues to output the detection signal to the second temperature sensor 240 and the timing signal to the timing unit 250, so as to realize real-time monitoring of the actual working temperature in the storage space in the bar 130, and ensure that the temperature in the storage space is relatively constant.
As shown in FIG. 5, a temperature control method 500 for a further control mode, such as a fast cooling mode, is also provided in a further embodiment of the present invention.
As shown in fig. 1, 2 and 5, in the rapid cooling mode, the temperature control method 500 of the bar 130 includes:
acquiring a target working temperature and a set time;
acquiring current time and calculating a time difference between the current time and the set time;
detecting the initial working temperature of a storage space in a bar counter, and calculating a first temperature difference between the initial working temperature and the target working temperature; and
acquiring a set rotating speed of an air supply device in a temperature control system of the bar counter according to the time difference value and the first temperature difference value; and
and controlling the air supply device to rotate according to the setting.
Specifically, when the main control board 260 recognizes that the current control mode is the fast cooling mode, it receives the target working temperature and the set time input to the main control board 260 in the fast cooling mode, wherein the set time corresponds to the target working temperature, specifically, when the set time is reached, the working temperature in the storage space needs to be equal to the target working temperature.
In addition, in the fast cooling mode, the target operating temperature is generally low, and at this time, the temperature control system 200 only needs to control the air supply device 210 to operate, so as to perform the cooling operation.
The main control board 260 calculates a time difference between the current time and the set time by acquiring the current time in the time module built in the refrigerator 100; the main control board 260 further detects an initial operating temperature of the storage space inside the bar 130, and calculates a first temperature difference between the initial operating temperature and a target operating temperature; and, according to the time difference and the first temperature difference, acquiring a set rotation speed of the air supply device 210 in the temperature control system 200 of the bar counter; and controlling the air supply device to operate according to the set rotating speed.
In a preferred embodiment, the step of detecting the initial working temperature of the storage space in the bar 130 by the main control board 260 further comprises: detecting the initial operating temperature of the storage space inside the bar 130 and starting timing; the step of obtaining the set rotational speed of the blower 210 in the temperature control system 200 of the bar specifically includes: acquiring the set rotating speed and the feedback time period; and detecting the current working temperature of the storage space in the bar counter again every time the accumulated time reaches a feedback time period.
In this embodiment, the set rotation speed and the feedback time period are obtained, and by comparing the cooling range of the actual working temperature in one feedback time period with the preset cooling range, it is determined whether the set rotation speed of the air supply device 210 is reasonable or not, and whether the target working temperature can be reached in the set time period. In addition, according to the comparison result of the cooling range of the actual working temperature in a feedback time period and the preset cooling range, the actual rotation speed of the air supply device 210 is reasonably adjusted, so that the accurate control of the air supply device 210 can be realized, and the intelligent air supply device is more intelligent and saves more energy.
Specifically, the present invention relates to a method for manufacturing a semiconductor device.
When a feedback time period is operated, the main control board 260 outputs a detection signal to the second temperature sensor 240, which re-detects the current working temperature of the storage space inside the bar 130, and the main control board 260 outputs a timing signal, and the timing unit 250 re-starts timing of the next feedback time period;
the main control board 260 calculates a second temperature difference between the current operating temperature and the target operating temperature;
comparing the second temperature difference value with a preset cooling range;
if the second temperature difference is greater than the preset cooling range, which indicates that the set rotational speed is too high and the cooling rate is too high, controlling the actual rotational speed of the air supply device 210 to be less than the set rotational speed, that is, reducing the actual rotational speed in the current feedback time period; if the second temperature difference is smaller than the preset cooling range, which indicates that the set rotational speed is too small and the cooling rate is low, the actual rotational speed of the air supply device 210 is controlled to be greater than the set rotational speed, i.e. the actual rotational speed is increased in the current feedback time period.
In addition, if the second temperature difference is equal to the preset cooling range, the air supply device 210 is controlled to continue to operate according to the set rotation speed in the current feedback time period.
The above steps are repeated repeatedly, the second temperature difference is periodically monitored, and the actual rotation speed of the air supply device 210 is adaptively reduced, increased or maintained, so that the accuracy of the working temperature regulation is improved. In addition, compared with the air supply device which always operates according to the set rotating speed, the air supply device which reasonably regulates and controls the actual rotating speed in a plurality of feedback periods obviously achieves the aim of saving energy.
In a preferred embodiment, the current operating temperature is equal to the target operating temperature, and when the current time is equal to the preset time, the fast cooling mode is turned off and the intelligent mode is turned on. And when the current control mode is identified as the intelligent mode, identifying the category of the object in the storage space.
This switching of control modes illustrates that the bar counter including the above-described temperature control methods 300, 400, 500 according to the present invention can use a variety of different application scenarios.
