Fig. 1 illustrates a schematic structural view of a front cross section of a refrigeration device 001 provided according to an embodiment of the present description; fig. 2 is a schematic diagram illustrating an oblique cross-sectional structure of a refrigeration apparatus 001 according to an embodiment of the present disclosure;

fig. 3 shows a partially enlarged schematic view of fig. 2. As shown in fig. 1 to 3, the refrigerating apparatus 001 may include a cabinet 100, a plurality of trays 300, and a duct. In some embodiments, the refrigeration appliance 001 may further include a refrigeration system 400. In some embodiments, the refrigeration device 001 may further comprise a baffle 600. In some embodiments, the refrigeration appliance 001 may also include a temperature control system 800.

The cabinet 100 may be a mounting base of the refrigeration apparatus 001, i.e., a body of the refrigeration apparatus 001. The interior of the case 100 may be a closed cavity. The box 100 may have a rectangular parallelepiped structure, or may have other structures, such as a cube, a prism, etc. For convenience of description, we will describe the case 100 as an example in which the interior thereof is a rectangular parallelepiped structure. As shown in fig. 1-2, the cabinet 100 may include side walls 110 and end walls 120. In some embodiments, the cabinet 100 may further include a door 130. In some embodiments, the cabinet 100 may further include a refrigeration compartment 160 and an evaporation compartment 140. In some embodiments, the enclosure 100 may also include a partition 180.

Taking the case that the interior of the box 100 is a rectangular parallelepiped, as shown in fig. 1 to 2, the box 100 may include a side wall 110 and an end wall 120. The sidewalls 110 may include a first sidewall 111, a second sidewall 112, a third sidewall, and a fourth sidewall (not shown in fig. 1-2). Wherein the first sidewall 111 may be disposed opposite to the second sidewall 112. The third sidewall may be disposed opposite the fourth sidewall. The third and fourth sidewalls may be disposed perpendicular to the first and

second sidewalls

111 and 112. The end wall 120 may include an upper wall and a lower wall. The upper wall may be connected to one end of the side wall 110. The lower wall may be connected to the other end of the sidewall 110. For convenience of description, the upper wall is connected to the upper end of the side wall 110, and the lower wall is connected to the lower end of the side wall 110. The end walls 120 are connected to the side walls 110 to form an interior cavity of the cabinet 100.

In some embodiments, the cabinet 100 may further include a door 130. The door 130 may be movably connected to the cabinet 100. Specifically, the door 130 may be hinged to the sidewall 110 of the cabinet 100 to open or close the cabinet 100. The door 130 may be connected to any one of the sidewalls 110 of the cabinet 100. For convenience of description, the door 130 is hinged to the first sidewall 111.

As shown in fig. 1 to 2, the inner cavity of the cabinet 100 may include a refrigerating chamber 160 and an evaporating chamber 140. The evaporation chamber 140 may be spaced apart from the refrigeration chamber 160. The refrigerating compartment 160 may be used as a freezing compartment having a relatively low temperature for storing general frozen foods, for example, having a temperature below-18 c, or below-15 c, or below-20 c, etc. The refrigerating chamber 160 may also be used as a refrigerating chamber for refrigerating and refreshing food, for example, the temperature thereof may be 0 to 10 ℃, or-2 to 10 ℃, and the like. The temperature of the refrigeration compartment 160 may be regulated and controlled by a temperature control system 800.

The evaporation chamber 140 is used for cooling the refrigeration system 400, forming cold air, and providing the cold air to the cooling chamber 160. Specifically, after the hot air enters the evaporation chamber 140, the refrigeration system 400 may cool the hot air in the evaporation chamber 140 to form cold air, and output the cold air to the refrigeration chamber 160, where the cold air refrigerates the refrigeration chamber 160 to reduce the temperature in the refrigeration chamber 160, so as to control the temperature in the refrigeration chamber 160 within a preset range. The evaporation chamber 140 may be disposed at one side of the cooling chamber 160 so as to absorb hot air inside the cooling chamber 160 into the evaporation chamber 140 and output cold air inside the evaporation chamber 140 into the cooling chamber 160. Specifically, the evaporation chamber 140 may be disposed at any one side of the cooling chamber 160, for example, an upper side, a lower side, a front side, a rear side, a left side, a right side, and the like. In order to facilitate the cool air output from the evaporation chamber 140 to smoothly enter the lower portion of the cooling chamber 160, the evaporation chamber 140 may be disposed at the upper side of the cooling chamber 160. For convenience of illustration, the evaporating chamber 140 is disposed on the upper side of the refrigerating chamber 160 for illustration.

In some embodiments, the evaporation chamber 140 may be a hot air chamber 142 and a cold air chamber 144. The warm air compartment 142 stores therein the hot air absorbed from the cooling compartment 160. The cool air compartment 144 stores therein cool air cooled by the cooling system 400. The hot air chamber 142 and the cold air chamber 144 can be communicated with each other, so that the hot air in the hot air chamber 142 enters the cold air chamber 144. The hot air chamber 142 and the cold air chamber 144 can be in one-way communication, so that the hot air in the hot air chamber 142 can enter the cold air chamber 144, and the air in the cold air chamber 144 cannot enter the hot air chamber.

The refrigeration compartment 160 and the evaporation compartment 140 may be separated by a partition 180. The partition 180 may be installed inside the cabinet 100. Specifically, the partition 180 may be installed on the sidewall 110 inside the cabinet 100. The partition 180 may be a unitary structure or may be formed from a combination of multiple pieces to serve as a partition between the evaporation compartment 140 and the refrigeration compartment 160. The evaporation compartment 140 may communicate with the refrigeration compartment 160 such that hot air may enter the evaporation compartment 140 from the refrigeration compartment 160 and cold air may enter the refrigeration compartment 160 from the evaporation compartment 140. As shown in fig. 1-3, the partition 180 may include an intake port 184 and an exhaust port 186. Specifically, the evaporation chamber 140 may be in communication with the refrigeration chamber 160 through the intake port 184 and the exhaust port 186. The hot air in the cooling compartment 160 enters the evaporation compartment 140 through the air inlet 184 and the cold air in the evaporation compartment 140 enters the cooling compartment 160 through the air outlet 186.

In order to avoid the short circuit between the cold air and the hot air, the distance between the air inlet 184 and the air outlet 186 should be as far as possible to prevent the cold air output from the air outlet 186 from short circuit and directly entering the air inlet 184 for cooling again. The air inlet 184 and the air outlet 186 may be respectively disposed at one side of the opposite sidewalls to increase a distance between the air inlet 184 and the air outlet 186. For example, the air inlet 184 and the air outlet 186 may be respectively disposed on the first side wall 111 and the second side wall 112, which are oppositely disposed, or may be respectively disposed on the third side wall and the fourth side wall, which are oppositely disposed. Taking the door 13 hinged to the first side wall 111 as an example, the door 130 is opened frequently, so that the temperature of the side of the cooling compartment 160 close to the door 130 is high. I.e. the side closer to the first side wall 111 has a higher temperature and the side further away from the first side wall 111 has a lower temperature. Therefore, the air inlet 184 may be disposed at a side close to the first sidewall 111 to allow the hot air to smoothly enter the evaporation chamber. The air outlet 186 is disposed at a side far from the first side wall 111, i.e. a side near the second side wall 112, so that the air outlet 186 is far from the air inlet 184.

As shown in fig. 1 to 3, in order to make the air inlet 184 and the air outlet 186 as far away as possible, the air inlet 184 may be disposed on a side of the partition plate 180 close to the first side wall 111 and facing the cooling compartment 160, that is, on a side of the partition plate 180 close to the first side wall 111 and facing the plurality of trays 300, that is, on a side downward of the partition plate 180. The air outlet 186 may be disposed at a side of the partition 180 adjacent to the second sidewall 112 and facing the second sidewall 112. Specifically, the partition 180 may have an L-shape. The L-shape has one side facing the refrigeration compartment 160, i.e., the plurality of trays 300, and the other side facing the second sidewall 112. The intake vent 184 may be disposed at a side of the partition 180 facing the cooling compartment 160, i.e., the plurality of trays 300, and the exhaust vent may be disposed at a side of the partition 180 facing the second sidewall 122 so as to be away from the intake vent 184, thereby preventing cold air output from the exhaust vent 186 from meeting hot air near the intake vent 184 to form an air short circuit.

In some embodiments, the partition 180 may include a first partition 181 and a second partition 182. A first barrier 181 may be installed on the sidewall 110 inside the cabinet 100 to separate the evaporation chamber 140 and the refrigeration chamber 160. A second partition 182 may be mounted to the side wall 110 or the end wall 120 of the interior of the cabinet 100 to separate the hot air compartment 142 from the cold air compartment 144. The intake vent 184 may be disposed on the first partition 181. The air outlet 186 may be disposed on the second partition 182.

As shown in fig. 1 to 2, the cooling device 001 may include a plurality of trays 300. A plurality of trays 300 may be installed in the refrigerating compartment 160. The tray 300 may be used to place or store items. A plurality of trays 300 may be coupled to the side wall 110. The plurality of trays 300 may be spaced apart along the extending direction of the side wall 110, for example, from top to bottom. The plurality of trays 300 may be connected to one of the sidewalls 110, for example, the first and

second sidewalls

111 and 112, or the third and fourth sidewalls. As previously described, the intake vent 184 is adjacent the first sidewall 111 and the exhaust vent 186 is adjacent the second sidewall 112. In order to allow the cool air to smoothly enter each tray 300, each tray 300 may be installed on, connected to, and spaced apart from the first and

second sidewalls

111 and 112, respectively. The tray 300 is spaced apart from the first sidewall 111 to form a first gap 301, and spaced apart from the second sidewall 112 to form a second gap 302. The first gap 301 is adjacent to the first sidewall 111 and the second gap 302 is adjacent to the second sidewall 112.

The air inlet 184, the air outlet 186, the first gap 301 and the second gap 302 form the air duct. When the refrigerating apparatus 001 operates, the cold air generated in the evaporation chamber 140 enters the refrigeration chamber 160 through the air outlet 186, and sequentially reaches the plurality of trays 300 along the second gap 302; the hot air in the cooling compartment 160 reaches the intake opening 184 along the first gap 301, and exits the cooling compartment 160 into the evaporation compartment 140 through the intake opening 184. As shown in fig. 1, the dotted arrows indicate the flow path of the cool air, and the solid arrows indicate the flow path of the hot air.

In order to allow the cold air and the hot air to flow along the path of the wind tunnel and avoid short circuit of the wind, each tray 300 may be matched with the contact surface of the third side wall and the fourth side wall, that is, the shape of the contact surface of the tray 300 and the third side wall and the fourth side wall is matched, so that the gap between the tray and the third side wall and the fourth side wall is as small as possible, and even can be closed, for example, by a sealing material, such as rubber.

In summary, the cooling device 001 forms the first gap 301 and the second gap 302 by providing the gap between the tray 300 and the first sidewall 111 and the second sidewall 112, and closes the rest, and forms the air duct of the cooling device 001 through the first gap 301 and the second gap 302, so that the cold air can sequentially reach each tray 300 along the air duct, thereby cooling each tray 300; and the air inlet 184 and the air outlet 186 in the refrigeration equipment 001 are arranged on different sides, so that the short circuit of air can be effectively avoided, and the refrigeration efficiency is improved. Through optimizing the installation relation between a plurality of trays 300, through sheltering from and the clearance between a plurality of trays 300, refrigeration plant 001 makes hot-air and cold air follow predetermined route and carries out the circulation flow, can make cold air can more evenly get into every tray 300, reduces the difference in temperature of different trays 300, has promoted refrigeration plant 001's use and has experienced.

Since the temperature in the evaporation chamber 140 is low, the temperature on the tray 300 closest to the evaporation chamber 140, i.e., the tray 300 of the first layer from the top to the bottom, is also low. In order to avoid excessive temperature difference between the tray 300 closest to the evaporation chamber 140 and other trays 300, the cool air may not enter the tray 300 closest to the evaporation chamber 140. At this time, a baffle 600 may be provided on the tray 300 closest to the evaporation chamber 140 to block the entrance of the cool air. Specifically, the baffle 600 may be vertically installed at an end of the tray 300 closest to the evaporation chamber 140 and close to the second sidewall 112, and contact or form a seal with the partition 180, the third sidewall and the fourth sidewall, so as to prevent the cold air from entering the tray 300 closest to the evaporation chamber 140, so that the cold air directly flows to the second-layer tray 300 from top to bottom and then starts to be emitted, thereby effectively improving the utilization rate of the cold air and also preventing the first tray 300 from having a problem of too low temperature.

In some embodiments, the refrigeration appliance 001 may further include a refrigeration system 400. As shown in fig. 1-3, the refrigeration system 400 may include an evaporator 420. In some embodiments, the refrigeration system 400 may also include a fan 440. In some embodiments, the refrigeration system may further include a compressor, a condenser, and a heat rejection fan (not shown in fig. 1-3).

The evaporator 420 may be installed in the evaporation chamber 140 and operates to cool the air in the evaporation chamber 140. Specifically, the evaporator 420 may be mounted within the cool air compartment 144. The compressor may be located inside the case 100. For example, the box 100 may further include a receiving cavity (not shown in fig. 1 to 3) for receiving the compressor and other devices, such as the condenser and the heat dissipation fan. The compressor may be connected to an evaporator 420 to form a refrigeration circuit. In refrigeration system 400, the outlet of the compressor may be connected to the inlet of the condenser, and the outlet of the condenser may be connected to the inlet of evaporator 420. The outlet of the evaporator 420 may be connected to the inlet of the compressor to form a refrigeration circuit. In the refrigeration process of the refrigeration circuit, the gaseous refrigerant enters the compressor, is compressed by the compressor, becomes a high-temperature high-pressure vapor refrigerant, enters the condenser for condensation, becomes a high-pressure low-temperature liquid refrigerant, enters the evaporator 420, absorbs heat in the evaporation chamber 140, becomes a gaseous refrigerant, and finally returns to the compressor to form a refrigeration cycle. During the refrigeration cycle of the refrigeration circuit, a large amount of heat is absorbed in the evaporation chamber 140 (the cold air chamber 144), so that a large amount of cold air can be formed in the evaporation chamber 140 (the cold air chamber 144). The heat radiation fan can radiate heat of the compressor and the condenser.

The blower fan 440 may be installed in the evaporation chamber 140. Specifically, the fan 440 may be installed in the hot air chamber 142. The fan 440 may include a suction side 442 and an outlet side 444. The suction side 442 of the fan 440 may face the intake vent 184. The air output side 444 of the fan 440 may face the evaporator 420. Specifically, the suction side 442 of the fan 440 may be located in the warm air chamber 142. The air output side 444 of the fan 440 may be located in the cool air compartment 144. The hot air chamber 142 and the cold air chamber 144 are communicated by a fan 440.

The fan 440 can provide power for the air flow in the air duct, so as to form a stable air flow direction. The fan 440 may employ a centrifugal fan. The fan 440 may draw air upward to draw the hot air in the cooling compartment 160 to the top of the cabinet 100, and the hot air is drawn into the evaporation compartment 140 through the air inlet 184, first into the hot air compartment 142, and then into the cold air compartment 144; the hot air is cooled by the evaporator 420 and then changed into cold air; the fan 440 blows cool air into the air duct through the air outlet 186, diffuses in the air duct, and flows downward into the tray 300 to cool the tray 300. The fan 440 may provide power to the air flow in both the intake 184 and the exhaust 186 directions.

In summary, the cooling device 001 may provide power for the air flow inside the cabinet 100 through the fan 440.

Fig. 4 shows a flowchart of a temperature control method P100 provided according to an embodiment of the present description. As previously described, control device 840 may perform temperature control method P100 described herein. Specifically, when the control device 840 is running, the processor may read the instruction set stored in its local storage medium and then execute the temperature control method P100 described herein according to the specification of the instruction set.

In some embodiments, the method P100 may include:

s110: receiving the plurality of temperature data.

Control device 840 may receive the plurality of temperature data based on the communication connection. The control device 840 may receive the temperature data in real time, or may receive the temperature data based on a preset time period, for example, receive the temperature data every 1 minute, receive the temperature data every 2 minutes, or receive the temperature data every 5 minutes, etc. The preset duration can be manually set or changed according to the use scene.

S130: based on the plurality of temperature data, a composite temperature of the refrigeration appliance 001 is determined.

The cooling device 001 includes a plurality of trays 300, and each tray 300 is located at a different position, and may have different temperatures. Therefore, the control device 840 needs to determine the integrated temperature in the refrigerating compartment 160 according to the temperature data of each tray 300 to control the start and stop of the compressor according to the integrated temperature in the refrigerating compartment 160. The integrated temperature may be an average temperature of the plurality of trays 300 or may be a temperature obtained by correcting the average temperature.

Specifically, step S130 may include:

s132: and carrying out mean value calculation on the plurality of temperature data based on a mean value algorithm to obtain the average temperature.

In some embodiments, the average temperature may be an average of the temperatures of all of the plurality of trays 300. In some embodiments, the average temperature may be an average of the temperatures of some of the trays 300 in the plurality of trays 300. For example, when there is an abnormality in the temperature data of a part of the trays 300 among the plurality of trays 300, the abnormal data may not be data calculated as an average value. For example, the abnormal data may be data indicating that the temperature is lower than a threshold low temperature value or exceeds a threshold high temperature value, such as data lower than-50 ℃, or data higher than 20 ℃, and so on. Step S132 may be selecting a target temperature meeting a preset decision logic from the plurality of temperature data based on the preset decision logic; and based on the mean algorithm, carrying out mean calculation on the target temperature to obtain the mean temperature difference. For example, the decision logic may be data between the extreme low temperature value and the extreme high temperature value, the decision logic may be to remove the highest data and the lowest data, and so on. If all the temperature data do not satisfy the decision logic, the temperature control method P100 is not started.

S134: based on the average temperature, the integrated temperature is determined.

In some embodiments, control device 840 may use the average temperature as the integrated temperature. In some embodiments, control device 840 may modify the average temperature to determine the integrated temperature. Since the temperature sensor 820 is mounted on the tray 300, the temperature of the tray 300 is measured, and the temperature of the items on the tray 300 is not directly measured. Therefore, the temperature of the items on the tray 300 may deviate from the data measured by the temperature sensor 820. Therefore, the average temperature needs to be corrected to obtain the integrated temperature.

Specifically, the control device 840 may store a mapping relationship between the temperature and the temperature difference in advance. Based on the mapping relationship and the average temperature, the control device 840 may determine a target temperature difference corresponding to the average temperature, and superimpose the average temperature and the target temperature difference to compensate the average temperature, so as to obtain the integrated temperature. The temperature and temperature difference mapping relation can be obtained in an experimental calibration mode. Specifically, when calibrating the temperature sensor 820, the mapping relationship between the temperature and the temperature difference can be obtained by measuring the temperature of the articles on the tray 300 and comparing the measured temperature with the data measured by the temperature sensor 820. In calibrating temperature sensor 820, the temperatures of a plurality of different locations of the items on the measurement tray 300, such as 3 locations, 4 locations, etc., may be collected, averaged, and the average temperature of the items on the tray 300 determined; and obtaining the difference between the data of the temperature sensor 820 and the average temperature of the article to obtain the temperature difference corresponding to the temperature data measured by the current temperature sensor 820. The temperature sensor 820 is calibrated by repeating the above steps in different temperature environments, so that the corresponding relationship between the temperature and the temperature difference in different temperature environments is obtained. Based on the calibration data of the temperature sensor 820, the temperature difference corresponding to each different temperature is obtained according to the normal distribution of the data, so that the mapping relation between the temperature and the temperature difference is obtained.

S150: and controlling the starting and stopping of the compressor based on the comprehensive temperature.

Specifically, step S150 may include one of the following cases:

s152: determining that the integrated temperature is lower than the first threshold value, and controlling the compressor to stop;

s154: and determining that the comprehensive temperature is higher than the second threshold value, and controlling the compressor to start.

As described above, the first threshold value and the second threshold value may be stored in advance in control device 840. When the integrated temperature exceeds the second threshold, which indicates that the temperature in the refrigeration compartment 160 is too high, the control device 840 may control the compressor to start to perform refrigeration so as to lower the temperature in the refrigeration compartment 160; when the integrated temperature is lower than the first threshold, indicating that the temperature in the refrigeration compartment 160 is too low, the control device 840 may control the compressor to stop. Specifically, the control device 840 may control the compressor to stop for a period of time to raise the temperature in the refrigeration compartment 160. The period of time may be any time, such as 10 minutes, 20 minutes, etc., and the period of time may be set or changed manually or may be learned by machine learning.

In summary, in the refrigeration apparatus 001 and the temperature control method P100 thereof provided in the present specification, the refrigeration apparatus 001 forms the first gap 301 and the second gap 302 by providing the gap between the tray 300 and the first sidewall 111 and the second sidewall 112, and is closed at the rest, and forms the air duct of the refrigeration apparatus 001 through the first gap 301 and the second gap 302, so that the cold air can sequentially reach each tray 300 along the air duct, thereby refrigerating each tray 300; and the air inlet 184 and the air outlet 186 in the refrigeration equipment 001 are arranged on different sides, so that the short circuit of air can be effectively avoided, and the refrigeration efficiency is improved.
