[0027] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0028] According to an embodiment of the present invention, a refrigeration structure is provided. Figures 1 to 3, comprising: a cold storage box 1, wherein the cold storage box 1 has a cold storage chamber 11; a mounting plate 2, connected to the cold storage box 1, the mounting plate 2 being located in the cold storage chamber 11 to separate the cold storage chamber 11 into a first cold storage chamber 10 and a second cold storage chamber 20; a refrigeration module 3, used for cooling a furnace body in the first cold storage chamber 10; a first fan component 4, mounted on the mounting plate 2, the first fan component 4 being used for blowing the airflow in the first cold storage chamber 10 to the second cold storage chamber 20; a second fan component 5, located below the first fan component 4; the second fan component 5 being mounted on the mounting plate 2, the second fan component 5 being used for blowing the airflow in the second cold storage chamber 20 to the first cold storage chamber 10.

[0029] Specifically, the fan on the first fan component 4 blows cold air into the second refrigeration chamber 20, so that the temperature in the second refrigeration chamber 20 is reduced; the fan of the second fan component 5 sucks the return air in the second refrigeration chamber 20 into the chamber of the refrigeration module 3. Under the return air pressure of the second fan component 5, the return air in the first refrigeration chamber 10 is smooth, so that the temperature in the refrigeration chamber 11 can be made more uniform without too much air volume. The fan speed is not high, no loud noise is generated, and the operation is more energy-saving, which solves the technical problem of the high noise of the fan in the Chinese medicine refrigerator in the related art.

[0030] Preferably, the first fan component 4 and the second fan component 5 of this embodiment are DC energy-saving fans.

[0031] Preferably, the blades of the second fan component 5 of this embodiment can be designed in a blowing form.

[0032] Specifically, see Figure 1 The refrigerator 1 in this embodiment includes a first side panel 12, and the first refrigeration chamber 10 is located between the first side panel 12 and the mounting plate 2. The refrigeration module 3 includes an evaporator 31 arranged on the first side panel 12. The fan of the second fan component 5 sucks the return air in the second refrigeration chamber 20 into the chamber of the refrigeration module 3 through the evaporator 31. In this way, the fan of the second fan component 5 does not need too much air volume to suck the return air in the second refrigeration chamber 20 into the chamber of the refrigeration module 3. The fan has a low speed, and the operation is more energy-saving, which reduces the cost.

[0033] Specifically, see Figure 1 In this embodiment, the evaporator 31 is spaced apart from the mounting plate 2 to form a first circulation channel 111 for air flow between the evaporator 31 and the mounting plate 2. The cold air sucked from the first refrigeration chamber 10 by the evaporator 31 flows through the first circulation channel 111, making the return air smooth and increasing fluidity.

[0034] Specifically, see Figure 1The refrigerator 1 in this embodiment includes a top plate 13 and a bottom plate 14, the bottom plate 14 is located above the top plate 13, one end of the first side plate 12 is connected to the top plate 13, the other end of the first side plate 12 is connected to the bottom plate 14, and the mounting plate 2 is detachably connected to the top plate 13; the mounting plate 2 and the bottom plate 14 are arranged at intervals, so that the mounting plate 2 can be fixed in the refrigerator 1 and is easy to disassemble. The spacing between the mounting plate 2 and the bottom plate 14 allows the return air to flow into the second refrigeration chamber 20 when the evaporator 31 inhales cold air from the first refrigeration chamber 10, and the return air has stronger circulation, thereby enhancing the temperature uniformity.

[0035] Specifically, see Figure 1 The refrigerator 1 in this embodiment also includes a second side plate 16, which is connected to the top plate 13, and the second side plate 16 is arranged to be spaced apart from the first side plate 12, and the refrigeration chamber 11 is located between the first side plate 12 and the second side plate 16; a flow port 112 is provided between the second side plate 16 and the bottom plate 14, and one end of the flow port 112 is connected to the refrigeration chamber 11, and the other end of the flow port 112 is connected to the outside of the refrigerator 1. This arrangement makes the entire refrigerator 1 firm but not closed, and the working state can be adjusted according to the temperature inside the refrigerator when the refrigerator 1 is working.

[0036] Specifically, see Figure 1 The refrigeration structure in this embodiment also includes a storage plate 6, which is connected to the mounting plate 2. The storage plate 6 and the second side plate 16 are arranged at intervals to form a second flow channel 113 between the storage plate 6 and the second side plate 16. This arrangement allows the cold air in the first refrigeration chamber 10 and the second refrigeration chamber 20 to flow into each other, thereby enhancing the temperature uniformity in the refrigeration chamber 11.

[0037] Specifically, see Figure 1 , Figure 2In this embodiment, there are multiple storage plates 6, and the multiple storage plates 6 are arranged at intervals in the vertical direction; a first placement cavity 114 is provided between the top storage plate 6 and the top plate 13, and the first fan component 4 is located in the first placement cavity 114; a second placement cavity 115 is provided between two adjacent storage plates 6, and the second fan component 5 is located in the second placement cavity 115. In this arrangement, when the refrigerator 11 is overheated or a large number of items are placed on the storage plates 6 in the entire refrigeration cavity 11, the first fan component 4 and the second fan component 5 both run at high speed, the first fan component 4 blows air, and the second fan component 5 sucks air, and the wind speed in the first placement cavity 114 and the second placement cavity 115 is increased. The air volume circulation is increased, thereby increasing the air volume circulation of the first refrigeration chamber 10 and the second refrigeration chamber 20, and the temperature in the entire refrigeration chamber 11 drops rapidly to meet the refrigeration demand; when a large number of items are placed on the upper storage plate 6, the first fan component 4 runs at a high speed, and the second fan component 5 runs at a lower speed, and performs refrigeration operation, so that the temperature in the second refrigeration chamber 20 drops rapidly; when a large number of items are placed on the lower storage plate 6, the second fan component 5 runs at a high speed, and the first fan component 4 runs at a lower speed, and performs refrigeration operation, so that the temperature in the first refrigeration chamber 10 drops rapidly; when there are fewer items on all storage plates, the first fan component 4 and the second fan component 5 both run at a lower speed. The speed of the first fan component 4 and the second fan component 5 are adjusted in real time to reduce the temperature difference between the first refrigeration chamber 10 and the second refrigeration chamber 20, so that the temperature uniformity in the refrigeration chamber 11 can be better maintained.

[0038] Specifically, see Figure 1 The refrigeration structure in this embodiment also includes: a first temperature sensor 7, connected to the mounting plate 2, and the first temperature sensor 7 is located in the first placement cavity 114; a second temperature sensor 8, located below the first temperature sensor 7; connected to the mounting plate 2, and the second temperature sensor 8 is located in the second placement cavity 115. In this way, when the temperature of the first temperature sensor 7 and the temperature of the second temperature sensor 8 are both high, the first fan component 4 and the second fan component 5 both run at high speed, the first fan component 4 blows air, and the second fan component 5 sucks air, increasing the air volume circulation, so that the temperature in the entire refrigeration cavity 11 drops rapidly, Meet the refrigeration demand; when the temperature of the first temperature sensor 7 is high, only the first fan component 4 is started for refrigeration operation to reduce the temperature in the second refrigeration chamber 20; when the temperature of the second temperature sensor 8 is high, only the second fan component 5 is started for refrigeration operation to reduce the temperature in the first refrigeration chamber 10; when the temperature difference between the first temperature sensor 7 and the second temperature sensor 8 is large, the fan speed of the first fan component 4 and the second fan component 5 is adjusted in real time to reduce the temperature difference between the first temperature sensor 7 and the second temperature sensor 8, so that the temperature uniformity in the refrigeration chamber 11 can be better.

[0039] Specifically, see Figure 1The refrigeration structure in this embodiment also includes a controller 9, which is signal-connected to the first fan component 4 and the second fan component 5. The controller 9 is used to control the rotation speed of the first fan component 4 and the second fan component 5. The controller 9 collects the temperature of the first temperature sensor 7 and the second temperature sensor 8, and compares it with the set temperature requirement, and is used to control the operation of the compressor 18, the first fan component 4 and the second fan component 5, so that the internal temperature of the refrigeration chamber 11 meets the requirement, thereby enhancing the temperature uniformity in the refrigeration chamber 11, and making the rotation speed and rotation time of the first fan component 4 and the second fan component 5 more reasonable, thereby reducing energy consumption and saving costs.

[0040] Specifically, see Figure 3 The present embodiment provides a control method, which is used in the refrigeration structure of any one of the above embodiments. The control method includes: measuring the temperature T1 at the first fan component 4 and the temperature T2 at the second fan component 5; comparing T1 and T2 with the threshold value T; if T1≤T, and T2>T, then reducing the rotation speed of the first fan component 4 and increasing the rotation speed of the second fan component 5; if T1>T, and T2>T, then increasing the rotation speeds of the first fan component 4 and the second fan component 5; if T1≤T, and T2≤T, then increasing the rotation speeds of the first fan component 4 and the second fan component 5, and reducing the rotation speed of the second fan component 5. This control method enables the first fan component 4 and the second fan component 5 to rotate under reasonable conditions, thereby improving temperature uniformity, reducing noise, and reducing costs.

[0041] Specifically, see Figure 3 , the first fan component 4 is an upper fan, and the second fan component 5 is a lower fan.
