Fig. 7 is a detailed flowchart of a method of controlling a refrigeration freezer in accordance with one embodiment of the present invention. The control method of the refrigeration and freezing equipment comprises the following steps:
step S702, acquiring all second temperature values of a second preset number of second areas 152 included in each first area 151;
step S704, determining a first temperature value of the first area 151 according to all the second temperature values;
step S706, determining that the second temperature values of all the second areas 152 are smaller than the second temperature threshold, if yes, performing step S714, and if no, performing step S708;
step 708, judging that the continuous operation time of the refrigeration system is greater than a preset time threshold, if so, executing step 714, and if not, executing step 710;

and step S714, controlling the refrigeration system to be closed.
In the above steps, each of the first regions 151 includes a second preset number of second regions 152. In a specific embodiment, the second preset number may be 16, i.e. each first region 151 comprises 16 second regions 152. Each second region 152 corresponds to a second temperature value. The step S714 of controlling the refrigeration system to be turned off may specifically be controlling the compressor and the fan to be turned off, and the damper to be closed.
Fig. 8 is a detailed flowchart of a control method of a refrigerating and freezing apparatus according to another embodiment of the present invention. The control method of the refrigeration and freezing equipment comprises the following steps:
step S802, obtaining all second temperature values of a second preset number of second areas 152 included in each first area 151;
step S804, determining a temperature condition of each first region 151 according to all second temperature values of a second preset number of second regions 152 included in each first region 151;
step S806, controlling the display device to display a color corresponding to the temperature condition of each first region 151.
In step S804, the temperature condition of each first region 151 is determined according to all the second temperature values of the second preset number of second regions 152 included in each first region 151, and in step S806, the display device is controlled to display a color corresponding to the temperature condition of each first region 151. In a specific embodiment, when the number of the second temperature values of the second preset number of second regions 152 included in the first region 151, which is smaller than or equal to the third temperature threshold value, is greater than or equal to the preset value, the display device displays that the corresponding first region 151 is in the first color;
when the number, which is greater than the third temperature threshold and less than or equal to the fourth temperature threshold, of all the second temperature values of the second preset number of second regions 152 included in the first region 151 is greater than or equal to a preset value, the display device displays that the corresponding first region 151 is in the second color;
when the number, which is greater than the fourth temperature threshold and less than or equal to the fifth temperature threshold, of all the second temperature values of the second preset number of second regions 152 included in the first region 151 is greater than or equal to a preset value, the display device displays that the corresponding first region 151 is in the third color;
when the number greater than the fifth temperature threshold value in all the second temperature values of the second preset number of second regions 152 included in the first region 151 is greater than or equal to the preset value, the display device displays that the corresponding first region 151 is in the fourth color.
For example, each of the 4 first regions 151 includes 16 second regions 152, the preset value is 3/4, and the display device displays corresponding colors when 12 or more of the 16 second temperature values are in the preset temperature range. One embodiment is described below: the third temperature threshold is 0 ℃, the fourth temperature threshold is 10 ℃, the fifth temperature threshold is 18 ℃, the first color is blue, the second color is green, the third color is yellow, and the fourth color is red. When 12 or more than 12 of the 16 second temperature values are less than or equal to 0 ℃, the color corresponding to the first region 151 is blue; when 12 or more of the 16 second temperature values are greater than 0 ℃ and less than or equal to 10 ℃, the color corresponding to the first region 151 is green; when 12 or more of the 16 second temperature values are greater than 10 ℃ and less than or equal to 18 ℃, the color corresponding to the first region 151 is yellow; when 12 or more than 18 ℃ out of the 16 second temperature values, the corresponding color of the first region 151 is red.
Under the condition that the temperature in the storage space 111 changes, the display device changes to a corresponding color only when 12 or more first regions 151 are in a preset temperature range among 16 second temperature values, otherwise, the display device can display a gradually changed color. For example, when the temperature in the storage space 111 decreases and a part of all the second temperature values in a certain first region 151 changes from greater than 0 ℃ to equal to or less than 10 ℃ to equal to or less than 0 ℃, but the number of temperature values is not greater than 12, the color displayed may be a gradual color from green to blue, rather than being directly displayed as blue. It should be noted that all the specific numerical values mentioned above are merely examples and do not limit the present invention. In other embodiments, other numbers and values may be provided.
According to the control method of the refrigeration and freezing equipment, the display device is arranged outside the refrigeration and freezing equipment 100 and is controlled to display the color corresponding to the temperature condition of each first region 151, so that the temperature conditions of different regions of the storage space 111 can be visually displayed, and the use experience of a user is improved.
