As shown in FIG. 1 to FIG. 3 , the present invention provides a temperature control method 300 for a refrigerator bar, which includes:

Detect the actual ambient temperature outside the bar;

Compare the actual ambient temperature with the preset ambient temperature;

If the actual ambient temperature is lower than the preset ambient temperature, the power supply to the temperature control system of the refrigerator bar is stopped.

As shown in FIG. 2 , the temperature control system 200 includes an air supply device 210 and a heating device 220 , and the air supply device communicates with the storage space (not shown) inside the bar counter 130 and the refrigerating or freezing compartment (not shown) inside the refrigerator 100 ).

In this embodiment, if the actual ambient temperature is lower than the preset ambient temperature, the power supply to the air supply device 210 and the heating device 220 is stopped, that is, the main energy-consuming components in the temperature control system 200 in the bar counter 130 are turned off, so as to achieve the purpose of energy saving .

As shown in FIG. 1 and FIG. 2 , the temperature control system 200 is arranged in the storage space inside the bar counter 130, and 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 is rotated 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 arranged on the outside or inside of the inner wall of the bar, and the inner wall is The shape defines the storage space, and the heating wire is activated to provide heat to increase the temperature in the storage space.

In addition, the temperature control system 200 further includes a first temperature sensor 230 disposed outside the bar counter 130 for detecting the actual ambient temperature.

The first temperature sensor 230 detects the actual ambient temperature and conducts it to the main control board 260. 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, and the storage unit stores the preset ambient temperature. , the processing unit receives the actual ambient temperature and reads the preset ambient temperature, 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 lower than the preset ambient temperature, it means that the temperature of the external environment is relatively low. At this time, even if the bar door of the bar counter 130 is frequently opened and closed, the actual working temperature in the storage space will not change significantly, and the output stops. The control command for supplying power to the air supply device 210 and the heating device 220 causes the bar counter 130 to enter an energy saving state to achieve the purpose of energy saving.

If the actual ambient temperature is greater than the preset ambient temperature, it means that the temperature of the external environment is relatively high. At this time, frequent opening and closing of the bar door of the bar counter 130 may easily cause the actual working temperature in the storage space to change significantly. The difference between the actual working temperature and the preset working temperature corresponds to the operation of the temperature control system 200 that controls the bar counter 130 to avoid increasing energy consumption.

As shown in FIG. 3 , according to the difference between the actual working temperature and the preset working temperature, the specific process corresponding to the operation of the temperature control system 200 for controlling the bar counter 130 includes:

Compare the difference between the actual working temperature and the preset working temperature with the preset difference;

If the difference between the actual working temperature and the preset working temperature is smaller than the preset difference, the heating device 220 is activated; if the difference between the actual working temperature and the preset working temperature is greater than the preset difference, the air supply is activated device 210.

In a preferred embodiment, if the difference between the actual working temperature and the preset working 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 , that is, the second temperature sensor 240 is disposed in the storage space inside the bar 130 .

In addition, the preset difference value is pre-stored in the storage unit of the main control board 260 .

As shown in Figure 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 to achieve a better storage experience.

Specifically, the temperature control system 200 further includes a timing unit 250, which starts timing when the actual working temperature inside the bar is detected when the actual ambient temperature is greater than the preset ambient temperature; whenever the accumulated timing reaches a predetermined time period, Recheck the actual working temperature inside the bar.

In other words, the main control board 260 determines that the actual ambient temperature is greater than the preset ambient temperature, and 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 working temperature inside the bar 130, and the timing unit 250 starts timing. When the timing unit 250 runs for a predetermined time period, it feeds back a timing completion signal to the main control board 260, and the main control board 260 repeatedly outputs the detection signal to the second temperature sensor 240 and the 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 timing, so as to repeat the detection and timing process, and provide the cooling capacity provided by the air supply device 210 or the heating device 220 within a predetermined time period. The actual working temperature is adjusted by the heat of the , so that the difference between the actual working temperature and the preset working temperature is equal to the preset difference.

Of course, it should be noted that, if the difference between the actual working temperature and the preset working temperature is equal to the preset difference within a current predetermined time period, after the current predetermined time period ends, the main control board 260 continues to output the detection signal The second temperature sensor 240 and the timing signal are sent to the timing unit 250 to realize real-time monitoring of the actual working temperature in the storage space in the bar counter 130 to ensure that the temperature in the storage space is relatively constant.

In addition, the steps of detecting the actual ambient temperature outside the bar include:

Identifying the current control mode, the control mode includes a storage mode, an intelligent mode and a quick cooling mode;

When it is recognized that the current control mode is the storage mode, the actual ambient temperature outside the bar is detected.

That is, the main control board 260 receives the control mode, which includes the storage mode, the smart mode and the quick cooling mode; when it is determined that the control mode is 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 panel of the refrigerator 100 through a cloud with a communication function, or may be directly input through the control panel on the door body 110 of the refrigerator 100 , and the control mode may be input by the refrigerator 100 . The main control board of the refrigerator 100 is recognized by the main control board of the refrigerator 100; or, the application program input on the smart terminal carried by the user is recognized by the main control board of the refrigerator 100 through data communication between the smart terminal and the refrigerator.

It should be noted that when the control mode is multiple modes, the main control board executes the steps in the temperature control method under different control modes according to different control modes, which can realize the multi-scenario application of the temperature control system of the bar counter to suit the user. different usage requirements.

As shown in FIG. 4 , in another embodiment of the present invention, a temperature control method 400 in another control mode, such as an intelligent mode, is also provided.

As shown in FIG. 1 , FIG. 2 and FIG. 4 , in the smart mode, the temperature control method 400 of the bar counter 130 includes:

Identify the categories of items placed in the storage space of the bar counter 130;

Get the storage temperature corresponding to the category of the item;

Calculate the difference between the actual operating temperature and the storage temperature; and

If the difference between the actual working temperature and the storage temperature is greater than the preset difference, the air supply device 210 in the temperature control system 200 of the bar counter 130 is activated; if the difference between the actual working temperature and the storage temperature is less than the preset difference value, the heating device 220 of the temperature control system 200 of the bar counter 130 is provided.

Specifically, when the main control panel 260 recognizes that the current control mode is the smart mode, it recognizes the categories of the items to be placed in the storage space, wherein the categories of items include, for example, fruits, dairy products, cosmetics, pharmaceutical preparations, and the like.

In a preferred embodiment, the step of identifying the category of the items put into the storage space of the bar further includes: pre-marking the category of the items put into the storage space. In the present invention, the user selects the name of the item to be put into the storage space through the application program on the smart terminal or the control panel on the door body 110 of the refrigerator 100. After the main control board 260 obtains the item name, it marks the item according to the item name. corresponding category.

In other embodiments of the present invention, the category mark of the item may also be a selection mark directly on the application program on the smart terminal or the control panel on the door body of the refrigerator. At this time, the main control board directly recognizes and puts it into the storage space The tag for the category of the item.

After the main control board 260 identifies the category of the item, it compares the acquired category with the category in the comparison table pre-stored in the storage unit, acquires the category consistent with the category in the comparison table and its corresponding storage temperature, and stores the corresponding category in the comparison table. The storage temperature is used as the best storage temperature for the category of the current item.

The main control board 260 continues to output the detection signal to the second temperature sensor 240 , and the second temperature sensor 240 is used for detecting the actual working temperature of the storage space and feeding back the detected actual working temperature to the main control board 260 .

After the main control board 260 obtains the actual working temperature, it reads the above-mentioned 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 the preset difference, and controls the The air supply device 210 and the heating device 220 in the temperature control system 200 work to make the difference between the actual working temperature and the storage temperature equal to the preset difference, so that the actual working temperature and the storage temperature are the same.

Wherein, if the difference between the actual working temperature and the storage temperature is greater than the preset difference, indicating that the actual working temperature is greater than the storage temperature, the air supply device 210 is activated, which guides the cold energy in the refrigerating or freezing compartment of the refrigerator 100 toward the storage temperature. to reduce the temperature in the storage space; if the difference between the actual working temperature and the storage temperature is smaller than the preset difference, which means that the actual working temperature is lower than the storage temperature, the heating device 220 is activated, and it faces the storage space. Heat is provided in the space to increase 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 can be stopped to achieve the purpose of energy saving.

As shown in FIG. 4 , the above step of obtaining the storage temperature corresponding to the category of the item further includes:

Obtain the set rotation speed of the air blowing device 210 corresponding to the category of the article, and the set heating rate of the heating device 220 corresponding to the category of the article.

By adapting the set rotation speed of the air supply device 210 and the set heating rate of the heating device 220 to the category of the article, in the process of adjusting the actual working temperature to be consistent with the storage temperature, it can be ensured that the temperature does not decrease or increase. affect the stored items. Taking vegetables and fruits as an example, the low-speed rotation of the air supply device 210 during the cooling process avoids the problem that the high-speed rotation of the air supply device 210 causes the water flow rate in the vegetables and fruits to be too fast and the preservation fails.

In this embodiment, the set rotational speed of the air supply device 210 and the set heating rate of the heating device 220 are stored in the aforementioned comparison table in advance, for example, and are in one-to-one correspondence with the categories of articles, that is, one category of articles corresponds to one storage temperature , a set speed and a set heating rate.

In addition, as shown in FIG. 4 , the step of detecting the actual working temperature of the storage space inside the bar counter 130 specifically includes:

When the actual working temperature of the storage space inside the bar counter 130 is detected, the timing is started; wherein, every time the accumulated timing reaches a predetermined time period, the actual working temperature of the storage space inside the bar counter 130 is re-detected.

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, and the preset difference is, for example, 0. When the difference between the actual working temperature and the storage temperature is 0, the items in the storage space can be kept in the best 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 working temperature inside the bar 130 , and the timing unit 250 starts timing. When the timing unit 250 runs for a predetermined time period, it feeds back a timing completion signal to the main control board 260, and the main control board 260 repeatedly outputs the detection signal to the second temperature sensor 240 and the 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 timing, so as to repeat the detection and timing process, and provide the cooling capacity provided by the air supply device 210 or the heating device 220 within a predetermined time period. The actual operating temperature is regulated by the amount of heat so that the difference between the actual operating temperature and the storage temperature is equal to the preset difference.

As shown in FIG. 5 , in yet another embodiment of the present invention, another temperature control method 500 in a control mode, such as a quick cooling mode, is also provided.

In addition, in the quick cooling mode, the target working temperature is usually low, and at this time, the temperature control system 200 usually only needs to control the air supply device 210 to work to perform the cooling operation.

The main control board 260 calculates the time difference between the current time and the set time by acquiring the current time in the built-in time module of the refrigerator 100; the main control board 260 further detects the initial working temperature of the storage space inside the bar counter 130, and calculates the initial operating temperature. the first temperature difference between the working temperature and the target working temperature; and, according to the time difference and the first temperature difference, obtain the set rotational speed of the air supply device 210 in the temperature control system 200 of the bar counter; and control the air supply The device runs at the set speed.

In a preferred embodiment, the step of further detecting the initial working temperature of the storage space inside the bar counter 130 by the main control board 260 specifically includes: detecting the initial working temperature of the storage space inside the bar counter 130 and starting timing; obtaining the temperature of the bar counter The step of setting the rotational speed of the air supply device 210 in the control system 200 specifically includes: obtaining the set rotational speed and the feedback time period; wherein, when the accumulated timing reaches a feedback time period, re-detecting the storage space inside the bar counter. Current operating temperature.

In this embodiment, the set rotational speed and the feedback time period are obtained, and by comparing the cooling range of the actual working temperature and the preset cooling range within a feedback time period, it is judged whether the set rotational speed of the air supply device 210 is reasonable and whether it can be Reach the target operating temperature within a certain time. In addition, according to the comparison result of the cooling range of the actual working temperature and the preset cooling range within a feedback time period, the actual rotation speed of the air supply device 210 can be adjusted reasonably, which can realize the precise control of the air supply device 210, which is more intelligent and also More energy efficient.

Specifically:

The main control board 260 calculates the second temperature difference between the current operating temperature and the target operating temperature;

comparing the second temperature difference with the preset cooling range;

Wherein, if the second temperature difference is greater than the preset cooling range, it means that the set rotational speed is too large and the cooling rate is too fast, then the actual rotational speed of the air supply device 210 is controlled to be less than the set rotational speed within the current feedback time period, that is, to reduce Actual rotational speed; if the second temperature difference is less than the preset cooling range, it means that the set rotational speed is too small and the cooling rate is low, then the actual rotational speed of the air supply device 210 is controlled to be greater than the set rotational speed within the current feedback time period, that is, the increase actual speed.

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 at the set rotational speed within the current feedback time period.

In addition, compared to an air supply device that always operates at a set rotational speed, an air supply device whose actual rotational speed can be reasonably regulated within multiple feedback cycles can obviously achieve more energy-saving purposes.

In a preferred embodiment, when the current working temperature is equal to the target working temperature, and the current time is equal to the preset time, the quick cooling mode is turned off and the smart mode is turned on.
