and step S30, controlling the evaporator fan 105 to be turned off in a delayed manner when the average temperature of the grids of the current row of cabinets 101 is lower than a second preset temperature.
The control method of the refrigerator 100 of the above embodiment can be realized by the refrigerator 100 of the present embodiment. The steps S10, S20, and S30 may be implemented by the controller 104. The controller 104 is used to obtain the average temperature of the compartments of each row of cabinets 101. The controller 104 is configured to sequentially control the condenser fan 103, the compressor 102, and the evaporator fan 105 corresponding to the current row of cabinets 101 to be turned on when the average temperature of the grid of the current row of cabinets 101 is greater than a first preset temperature. The controller 104 is configured to control the evaporator fan 105 to be turned off in a delayed manner when the average temperature of the grids of the current row of cabinets 101 is lower than a second preset temperature. Wherein the second preset temperature is lower than the first preset temperature.

In particular, in this embodiment, the refrigerator 100 may be understood as an intelligent cabinet having a refrigerating and/or freezing function, and in one embodiment, the refrigerator 100 may be used to place foods such as fresh foods delivered by a delivery person. In other embodiments, cooler 100 may also have a refrigerated and/or frozen merchandiser in which the operator may place food products to be refrigerated and/or frozen.
In the present embodiment, the plurality of rows of cabinets 101 may be understood as three or more rows of cabinets 101. Wherein, when the row number of the cabinet 101 is an even number, a group of evaporator fans 105 may be disposed between every two rows of the cabinet 101. When the number of rows of the cabinet 101 is odd, after a group of evaporator fans 105 is arranged between every two rows of the cabinet 101, the remaining one row of the cabinet 101 can be independently used by one group of evaporator fans 105 according to actual design requirements, which is not limited herein.
In this embodiment, the average temperature of the cells of each row of cabinets 101 may be understood as, in one embodiment, calculating an average of temperature values at preset positions of each cell of each row as the average temperature of the cells of each row of cabinets 101; in another embodiment, the temperature value of the preset position of a specific cell in each row is selected as the average cell temperature of each row of cabinets 101; in yet another embodiment, the average of the temperature values at different locations of the respective compartments in each row is calculated as the average compartment temperature for each row of cabinets 101.
In this embodiment, referring to fig. 2 to 4, the refrigerator 100 includes an evaporator 107 and a temperature sensor 108, and the controller 104 is connected to the evaporator 107 and the temperature sensor 108. The evaporator fan 105 is opposite to the evaporator 107 and is positioned right in front of the evaporator 107, the side wall of the lattice of the cabinet body 101 is provided with an air supply outlet 115, the back wall of the lattice of the cabinet body 101 is provided with an air return outlet 116, the right in front of the evaporator 107 is provided with an air supply duct 117, the back wall of the lattice of the cabinet body 101 is provided with an air return duct 118, and the temperature sensor 108 is arranged on the air return duct 118. Thus, the air intake and return circulation in the grid is formed by the action of the evaporator fan 105, and the refrigeration and cooling circulation in the grid is completed. The wind pressure in the narrow and long closed air supply duct 117 is large, the side wall of each grid opening is provided with a reasonable air inlet, and cold air can uniformly and effectively enter each grid opening under the action of the evaporator fan 105, so that the refrigeration in the grid openings is uniform, and the temperature difference between the upper grid opening and the lower grid opening is small. A temperature sensor 108 is provided in the return air duct 118 to accurately detect the temperature in the compartment. In fig. 4, the left two columns and the right two columns can be separated, and the return air duct 118 is provided with the temperature sensor 108, so that the temperature of the cabinet in the left two columns and the temperature of the cabinet in the right two columns can be separately detected, and the controller 104 controls the refrigeration and cooling in the left two columns and the cooling in the right two columns.
Referring to fig. 1 and fig. 2, in step S10 of the present embodiment, each row of cabinets 101 is installed with a temperature sensor 108, the temperature sensor 108 can detect the average cell temperature of the row of cabinets 101, and the temperature sensor 108 can transmit the average cell temperature of each row of cabinets 101 to the controller 104.
In step S20 of this embodiment, when the average temperature of the crates of the current row of cabinets 101 is greater than the first preset temperature, it indicates that the cooling effect of the current row of cabinets 101 does not reach the standard. At this time, the controller 104 sequentially controls the condenser fan 103, the compressor 102 and the evaporator fan 105 corresponding to the current row of cabinets 101 to be turned on, so that the refrigerant in the refrigerator 100 can be uniformly distributed to the cells of the current row of cabinets 101, and the average cell temperature of the current row of cabinets 101 is gradually reduced.
In this embodiment, referring to fig. 5, step S20 further includes:
step S21, when the average temperature of the grids of the current row of cabinets 101 is higher than a first preset temperature, controlling the condenser fan 103 to be started;
step S22, after the condenser fan 103 is started for a first preset time, the compressor 102 is controlled to be started;
in step S23, after the compressor 102 is turned on for a second preset time period, the evaporator fan 105 is controlled to be turned on.
The control method of the refrigerator 100 of the above embodiment can be realized by the refrigerator 100 of the present embodiment. The steps S21, S22, and S23 may be implemented by the controller 104. That is, the controller 104 is configured to control the condenser fan 103 to be turned on when the average temperature of the crates of the front row of cabinets 101 is greater than the first preset temperature. The controller 104 is configured to control the compressor 102 to be turned on after the condenser fan 103 is turned on for a first preset time period. The controller 104 is configured to control the evaporator fan 105 to turn on after the compressor 102 is turned on for a second preset time period. Thus, the condenser 106 of the present embodiment is turned on before the compressor 102 to dissipate heat from the compressor 102, which is beneficial to prolonging the life of the refrigeration system of the refrigerator 100, and meanwhile, after the recompressor 102 is turned on, the evaporator fan 105 is turned on in a delayed manner, so that the refrigerant of the refrigerator 100 flows in the evaporator 107 for a period of time first, and the refrigerant is uniformly distributed in the evaporator 107, thereby making the refrigeration of the refrigerator 100 more uniform.
In step S30 of this embodiment, when the average temperature of the cells of the current row of cabinets 101 is lower than the second preset temperature, it indicates that the average temperature of the cells of the current row of cabinets 101 has already been reduced to the second preset temperature, and meets the standard of refrigeration. In this case, the evaporator fan 105 may be controlled to be turned off with a delay. Since the temperature of the current cabinet 101 is still relatively low when the cooling operation is stopped, the cooling capacity can be fully utilized by turning off the evaporator fan 105 in a delayed manner.
In this embodiment, referring to fig. 6, a control method of the refrigerator 100 includes:
step S40, when the average temperature of the grids of each row of cabinets 101 is less than a second preset temperature, the compressor 102 is controlled to be closed;
and step S50, controlling the condenser fan 103 to be turned off after the compressor 102 is turned off for a fifth preset time period.
The control method of the refrigerator 100 of the above embodiment can be realized by the refrigerator 100 of the present embodiment. The steps S40 and S50 can be implemented by the controller 104. That is, the controller 104 is configured to control the compressor 102 to be turned off when the average temperature of the cells of each row of cabinets 101 is less than the second preset temperature. The controller 104 is configured to control the condenser fan 103 to be turned off after the compressor 102 is turned off for a fifth preset time period.
Thus, when the average temperature of the cells of each row of cabinets 101 is lower than the second preset temperature, the refrigerating temperature of the refrigerator 100 at this time reaches the standard refrigerating temperature. In this case, the compressor 102 can be controlled to be turned off to reduce power consumption of the refrigerator 100. After the compressor 102 is turned off for a fifth preset time period, the condenser fan 103 is controlled to be turned off, so that the condenser fan 103 can radiate heat to the compressor 102.
In one embodiment, referring to fig. 3, the number of the cabinets 101 of the refrigerator 100 is four, two rows of the cabinets 101 on the left side and two rows of the cabinets 101 on the right side, a set of the evaporator 107 and the evaporator fan 105 is disposed between the two rows of the cabinets 101 on the left side, and a set of the evaporator 107 and the evaporator fan 105 is also disposed between the two rows of the cabinets 101 on the right side. When the refrigerator 100 with four rows of cabinet bodies 101 needs to refrigerate, the average temperature of the grids of the left two rows of cabinet bodies 101 is detected, if the average temperature of the grids of at least one row of cabinet bodies 101 in the left two rows of cabinet bodies 101 is higher than a first preset temperature, the condenser fan 103 is started immediately, the compressor 102 is started after the condensation is started in a grading manner by delaying for 30 seconds, the evaporator fan 105 between the left two rows of cabinet bodies 101 is started after delaying for 60 seconds, and the grids of the left two rows of cabinet bodies 101 are refrigerated and cooled. It should be noted that the number of the left evaporator fans 105 may be designed to be plural according to actual requirements.
The average temperature of the grids of the two right rows of cabinet bodies 101 is detected, if the average temperature of the grids of at least one row of cabinet bodies 101 in the two right rows of cabinet bodies 101 is higher than a first preset temperature, the condenser fan 103 is started immediately, the compressor 102 is started after the condensation is started in a grading manner for 30 seconds in a delayed manner, the evaporator fan 105 between the two right rows of cabinet bodies 101 is started after the condensation is started in a graded manner for 60 seconds in a delayed manner, and the grids of the two left rows of cabinet bodies 101 are cooled. It should be noted that the number of the right evaporator fans 105 may be designed to be plural according to actual requirements.
If the average temperature of the grids of the left two rows and the right two rows of cabinet bodies 101 is higher than the first preset temperature, the evaporator fans 105 between the left two rows and the right two rows of cabinet bodies 101 are delayed for 60 seconds to be started, and all the grids of the four rows of cabinets are refrigerated and cooled. If four-row freezer 100 reaches the refrigeration temperature, when needing to stop refrigerating, detect the average temperature of the grid of the cabinet body 101 of two left and two right rows, if the average temperature of the grid of two left rows is less than the second and predetermines the temperature, then left side evaporimeter fan 105 group delay 30 seconds and close, two rows of cabinet grids on the left side stop refrigeration cooling. If the average temperature of the grids of the two rows of cabinet bodies 101 on the right side is lower than the second preset temperature, the right evaporator fan 105 group is turned off after being delayed for 30 seconds, and the two rows of cabinet grids on the right side stop refrigerating and cooling.
