In some embodiments, the container 10 includes a first region 140 and a second region 150 spaced apart from each other, and it should be noted that a plurality of first regions 140 and a plurality of second regions 150 are disposed in the container 10, and each region is spaced apart from each other. It will be appreciated that the first and second regions 140, 150 may be anywhere within the housing, for example, the first and second regions 140, 150 may each be disposed on opposing sidewalls within one of the chambers; alternatively, the first region 140 and the second region 150 are disposed at different positions on the same sidewall in one chamber, respectively; alternatively, the first region 140 and the second region 150 are disposed on different sidewalls of different chambers, respectively. It is understood that the positions of the first region 140 and the second region 150 may be set according to practical applications, and are not limited in particular.
In other embodiments, bladder 10 includes a first region 140, a second region 150, and a third region 160 spaced apart from one another. It is understood that the first zone 140, the second zone 150, and the third zone 160 can be anywhere within the enclosure. For example, the first region 140, the second region 150, and the third region 160 are respectively disposed in different chambers on the same sidewall; alternatively, the first, second and third regions 140, 150, 160 are disposed on different sidewalls within the same chamber, respectively; alternatively, the first, second and third regions 140, 150 and 160 are disposed on different sidewalls within different chambers, respectively. When the temperature difference between any two of the temperature of the first zone 140, the temperature of the second zone 150, and the temperature of the third zone 160 is not within the threshold range, the motorized damper 30 will modulate. It is understood that the positions of the first region 140, the second region 150, and the third region 160 may be set according to practical applications, and are not limited in particular.
In the present embodiment, the case that the tank container 10 includes the first region 140 and the second region 150 that are disposed at an interval is taken as an example for explanation, but the case that the tank container 10 includes the first region 140 and the second region 150 is only taken as an example for explanation, and the case that the tank container 10 is not limited.

A plurality of temperature sensing elements 20 may be provided in the first region 140, and a plurality of temperature sensing elements 20 may be provided in the second region 150. Each temperature sensing assembly 20 is spaced apart from each other.
The main control board 40 is respectively electrically connected with the plurality of temperature sensing assemblies 20 and the electric air door 30, the main control board 40 obtains a temperature difference value according to the first temperature value and the second temperature value, and when the temperature difference value is not within the threshold range, the main control board 40 controls the electric air door 30 according to the temperature difference value so as to reduce the temperature difference value.
The temperature difference is not within the threshold range, and the temperature difference between the temperatures measured by any two temperature sensing units 20 of the plurality of temperature sensing units 20 may not be within the threshold range. For example, if the temperature difference between the temperatures measured by the two temperature sensing assemblies 20 distributed in the first area 140 is not within the threshold range, the main control board controls the electric damper according to the temperature difference to reduce the temperature difference. For another example, if the temperature difference between the temperature measured by one of the temperature sensing elements 20 distributed in the first area 140 and the temperature measured by one of the temperature sensing elements 20 distributed in the second area 150 is not within the threshold range, the main control board controls the electric damper according to the temperature difference to reduce the temperature difference. The electric damper 30 is located on the cabinet container 10, and the electric damper 30 is used for adjusting the air volume, so that the temperature around the first side wall 110 and the temperature around the second side wall 120 can be adjusted by controlling the air volume to the first side wall 110 and the second side wall 120.
In the present embodiment, at least one first temperature sensing element 210 and at least one second temperature sensing element 220 are respectively disposed on the opposite sidewalls of the container 10. Specifically, at least one first temperature sensing element 210 in the plurality of temperature sensing elements 20 is disposed on the first sidewall 110, and is configured to measure a temperature of a first area close to the first sidewall 110 to obtain a first temperature value; the at least one second temperature sensing element 220 is disposed on the second sidewall 120, and is configured to measure a temperature of a second region close to the second sidewall 120 to obtain a second temperature value.
Please refer to fig. 5, in which fig. 5 is a schematic structural diagram of a third refrigerator according to an embodiment of the present disclosure. The motorized damper 30 includes a first damper 310 and a second damper 320, the first damper 310 being used to regulate the temperature of the first zone and the second damper 320 being used to regulate the temperature of the second zone.
The third side wall 130 of the refrigerator 100 is provided with a first air duct 330 and a second air duct 340, and the first air duct 330 includes a plurality of first sub-air ducts leading to the first side wall 110 for guiding the air from the first damper 310 to the first side wall 110. The second air duct 340 includes a plurality of second sub-air ducts leading to the second side wall 120 for guiding the air from the second damper 320 to the second side wall 120. Specifically, the air coming out of the first damper 310 flows to the first sub-air passage through the first air passage 330, and then enters the first side wall 110 to regulate the temperature of the first side wall 110. The air from the second damper 320 flows to the second sub-air passage through the second air passage 340, and then enters the second side wall 120 to regulate the temperature of the second side wall 120. The first damper 310 changes the amount of air flowing to the first sidewall 110 by adjusting the opening angle of the damper, thereby adjusting the temperature of the first sidewall 110. The second damper 320 changes the amount of air flowing to the second sidewall 120 by adjusting the opening angle of the damper, thereby adjusting the temperature of the second sidewall 120.
Illustratively, when a first temperature value of the first area measured by the first temperature sensing assembly 210 is different from a second temperature value of the second area measured by the second temperature sensing assembly 220, the main control board 40 obtains a temperature difference value according to the first temperature value and the second temperature value, compares the temperature difference value with a range value of a threshold value, and when the temperature difference value is not within the range value of the threshold value, the main control board 40 sends a control signal to the electric damper 30 according to the first temperature value and the second temperature value, and controls the adjustment of the electric damper 30 until the temperature difference value of the first temperature value and the second temperature value is within the range value of the threshold value.
Specifically, when the first temperature value is greater than the second temperature value, the main control board 40 sends a control signal to control the opening angle of the first damper 310 to be increased, so that the amount of cold air flowing to the first sidewall 110 is increased, and further the first temperature value of the first area is reduced until the temperature difference value is adjusted to be within the threshold range. It should be noted that the main control board 40 may also send a control signal to control the opening angle of the second damper 320 to decrease, so that the amount of cold air flowing to the second sidewall 120 decreases, and further the second temperature value of the second area increases until the temperature difference value is adjusted to be within the threshold range. In some embodiments, the main control board 40 may also send out a control signal to control the opening angle of the first damper 310 to become larger and the opening angle of the second damper 320 to become smaller, so as to decrease the first temperature value of the first area and increase the second temperature value of the second area, and increase the speed at which the temperature difference is adjusted to be within the threshold range.
When the second temperature value is greater than the first temperature value, the main control board 40 sends a control signal to control the opening angle of the second damper 320 to be increased, so that the amount of cold air flowing to the second sidewall 120 is increased, and further the second temperature value of the second area is reduced until the temperature difference value is adjusted to be within the threshold range. It should be noted that the main control board 40 may also send a control signal to control the opening angle of the first damper 310 to decrease, so that the amount of cold air flowing to the first sidewall 110 decreases, and further the first temperature value of the first area increases until the temperature difference is adjusted to be within the threshold range. In some embodiments, the main control board 40 may also send out a control signal to control the opening angle of the second damper 320 to become larger and the opening angle of the first damper 310 to become smaller, so that the second temperature value of the second area is decreased and the first temperature value of the first area is increased, and the speed of adjusting the temperature difference value to be within the threshold range is increased.
When the temperature difference is adjusted to be within the threshold range, the main control board 40 controls the opening angle of the first damper 310 to be the same as the opening angle of the second damper 320, and monitors the temperatures of the two sides of the refrigerator 100, so that the temperatures of the two sides of the refrigerator 100 are kept uniform. This embodiment carries out real-time control to the temperature of refrigerator 100 both sides through first temperature sensing subassembly 210 and second temperature sensing subassembly 220, when the temperature difference value of both sides is not at the threshold value scope, main control board 40 sends control signal and controls electric air door 30, the size of air output can be adjusted to electric air door 30, until the temperature difference value of both sides is in the threshold value scope, and then avoided because refrigerator 100 inner space is big, the wind gap size leads to inside temperature inhomogeneous with factors such as amount of wind size, lead to the problem that cold volume's utilization ratio is low, make the temperature of refrigerator 100 both sides reach balance, the problem of refrigerator 100 both sides temperature inhomogeneous has been improved.
It should be noted that, in some embodiments, the electrically operated damper 30 further includes a through hole and a switch disposed on the third side wall 130, and the through hole and the switch are used for guiding the air volume of the first damper 310 and the air volume of the second damper 320 to the third side wall 130, so as to adjust the temperature on the third side wall 130, so that the temperature difference between the third side wall 130, the first side wall 110, and the second side wall 120 is within a threshold range. So that the temperature of the refrigerator 100 is equalized.
The refrigerator 100 further includes a plurality of shelves 50, one end of each shelf 50 is connected to the first sidewall 110, the other end of each shelf 50 is connected to the second sidewall 120, the plurality of shelves 50 divide the refrigerator 100 into a plurality of independent chambers, a first temperature sensing assembly 210 is disposed in each chamber corresponding to the first sidewall 110, and the first temperature sensing assembly 210 is used for detecting the temperature around the first sidewall 110 in the corresponding chamber. The second side wall 120 is provided with a second temperature sensing element 220 corresponding to each chamber, and the second temperature sensing element 220 is used for detecting the temperature around the second side wall 120 in the corresponding chamber.
It should be noted that the first chamber 60 and the second chamber 70 are not necessarily disposed adjacently, at least two shelves 50 may be disposed between the first chamber 60 and the second chamber 70 at intervals, or one shelf 50 may be disposed between the first chamber 60 and the second chamber 70 at intervals.
The embodiment is described by taking an example of disposing a shelf 50 between the first chamber 60 and the second chamber 70, but not limited thereto. Illustratively, the shelf 50 divides the refrigerator 100 into separate first and second compartments 60, 70. The first temperature sensing element 210 of the first chamber 60 measures a third temperature value, and the second temperature sensing element 220 of the second chamber 70 measures a fourth temperature value.
In some embodiments, when the difference between the third temperature value and the fourth temperature value is not within the threshold range, the main control board 40 controls the motorized damper 30 according to the difference so that the difference is decreased. Such that the temperature of the first chamber 60 and the temperature of the second chamber 70 are in equilibrium. The temperature uniformity between chambers of each layer can be rapidly improved, and energy is saved.
Specifically, the first temperature sensing element 210 is connected to the first damper 310, the first temperature sensing element 210 detects the temperature around the first sidewall 110 of the first chamber 60 to obtain a third temperature value, and the second temperature sensing element 220 detects the temperature around the second sidewall 120 of the second chamber 70 to obtain a fourth temperature value.
When the temperature difference between the third temperature value and the fourth temperature value is not within the threshold range, and the third temperature value is higher than the fourth temperature value, that is, the temperature of the first chamber 60 is higher than the temperature of the second chamber 70. The main control panel 40 controls the first damper 310 arranged on the first chamber 60 to open, so that the cool air enters the first chamber 60, cools the first chamber 60, and controls the speed of the cool air entering the first chamber 60, that is, the cooling speed of the first chamber 60, by increasing the degree of the opening angle of the first damper 310. In some embodiments, the main control panel 40 controls the opening angle of the second damper 320 provided in the second chamber 70 to be decreased, so that the amount of cool air introduced into the second chamber 70 is decreased. In other embodiments, the main control panel 40 controls the second damper 320 disposed in the second chamber 70 to close, and stops the supply of cold air into the second chamber 70.
When the third temperature value is lower than the fourth temperature value, i.e., the temperature of the second chamber 70 is higher than the temperature of the first chamber 60. The main control panel 40 controls the second damper 320 arranged on the second chamber 70 to open, so that the cool air enters the second chamber 70, cools and cools the second chamber 70, and controls the speed of the cool air entering the second chamber 70, namely the cooling speed of the second chamber 70, by increasing the degree of the opening angle of the second damper 320.
