Description

Technical Field

[0001] The present invention relates to the technical field of fresh-keeping equipment, and in particular to an anti-condensation control method, device, equipment and storage medium for fresh-keeping equipment. Background Art

[0002] Currently, common fresh-keeping equipment, such as freezers and refrigerators, slows bacterial growth by lowering the internal temperature, thereby extending the shelf life of food stored within the equipment. However, some food, such as fruits and vegetables, continuously produces water vapor due to physiological activity, increasing the humidity within the equipment. Consequently, when temperature fluctuations occur within the equipment, such as when the equipment cools food above its internal temperature, condensation forms within the high-humidity equipment. This condensation not only affects the user experience but also the preservation of the food. Therefore, effectively reducing the risk of condensation in fresh-keeping equipment has become a pressing issue. Summary of the Invention

[0003] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art, and to provide an anti-condensation control method, device, equipment and storage medium for fresh-keeping equipment, which can effectively reduce the condensation risk of fresh-keeping equipment and help improve the fresh-keeping effect of fresh-keeping equipment on food.

[0032] The operation control device provided by the embodiment of the present invention has at least the following beneficial effects: when the fresh-keeping device is turned on, a violent gas exchange occurs between the inside of the box and the outside world, resulting in temperature fluctuations in the internal environment of the box. Therefore, the switch state of the box can be used to determine whether the temperature fluctuation occurs inside the box; and the sensed temperature is obtained by measuring the contact of the food in the box with the temperature measuring component, which can more accurately reflect the temperature and physiological activity intensity of the food itself. In addition, the humidity of the box is a key factor affecting the generation of condensation inside the box.

In addition, the humidity of the box is a key factor affecting the generation of condensation inside the box. Therefore, the condensation risk of the box can be evaluated by comprehensively considering the switch state of the box, the sensed temperature and the humidity of the box, thereby helping to control the operation of the decondensation device, the deoxygenation device and the compressor of the fresh-keeping device, and accurately lowering the temperature of the food. The deoxygenation device can also be used to reduce the oxygen content inside the box to suppress the generation of water vapor in the food.

[0036] The fresh-keeping device provided according to the embodiment of the present invention has at least the following beneficial effects: when the fresh-keeping device is turned on, a violent gas exchange occurs between the inside of the box and the outside world, resulting in temperature fluctuations in the internal environment of the box. The switch state of the box can be detected by the switch detection component and the box switch state can be generated, and then the box switch state can be used to determine whether temperature fluctuations occur inside the box; since the heat-conducting component at the bottom of the box can be in direct contact with the food, the heat of the food can be transferred through the heat-conducting component, so that the temperature sensor installed on the heat-conducting component can accurately measure the sensed temperature of the food and accurately reflect the physiological activity intensity of the food. The decondensation device can exchange the high-humidity gas inside the box with the low-humidity gas in the external environment to reduce the humidity of the box; the deoxygenation device can consume the oxygen inside the box, create a low-oxygen environment, effectively inhibit the physiological activities of food ingredients, and reduce the generation of water vapor; therefore, the parameters affecting the condensation risk inside the box can be accurately measured through switch detection components, temperature sensing and temperature sensors, which helps to accurately judge the condensation risk inside the box, thereby assisting the operation of the decondensation device, deoxygenation device and compressor inside the fresh-keeping equipment, helping to improve the fresh-keeping performance of the fresh-keeping equipment and reduce the condensation risk of the fresh-keeping equipment.

In addition, the humidity of the box is a key factor affecting the generation of condensation inside the box. Therefore, the condensation risk of the box can be evaluated by comprehensively considering the switch state of the box, the sensed temperature and the humidity of the box, thereby helping to control the operation of the compressor of the decondensation device, the deoxygenation device and the fresh-keeping device, and accurately lowering the temperature of the food. The deoxygenation device can also be used to reduce the oxygen content inside the box to suppress the generation of water vapor in the food. At the same time, the decondensation device can be used to timely discharge the water vapor inside the box, effectively reducing the condensation risk of the fresh-keeping device, which is beneficial to improving the fresh-keeping effect of the fresh-keeping device on the food.

[0057] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it should not be understood as a limitation on the scope of protection of the present invention.

[0058] In the description of the present invention, "several" means one or more, "more" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. "At least one" refers to one or more, "at least one of the following" and similar expressions refer to any combination of these items, including any combination of single or plural items. The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0059] It should be noted that the terms "dispose," "install," and "connect" in the embodiments of the present invention should be interpreted broadly. Those skilled in the art can reasonably determine the specific meanings of these terms in the embodiments of the present invention based on the specific content of the technical solution. For example, the term "connect" can refer to mechanical connection, electrical connection, or communication; it can be direct connection or indirect connection through an intermediary.

[0060] It should be noted that the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0061] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0062] At present, fresh-keeping equipment mainly delays the growth of bacteria and inhibits the physiological activities of food by lowering the temperature inside the equipment, thereby extending the shelf life of food. However, some food, such as fruits and vegetables, still maintain their physiological activities in a low-temperature environment, thereby generating water vapor, which increases the humidity inside the fresh-keeping equipment. When there is an area with a large temperature difference inside the fresh-keeping equipment, such as when the fresh-keeping equipment cools food that is higher than the temperature inside the equipment, or when temperature fluctuations occur, condensation is likely to occur inside the fresh-keeping equipment with high humidity. Condensation will not only affect the user experience, but also accelerate the decay of food, affecting the fresh-keeping effect of the fresh-keeping equipment on food. In related technologies, temperature and humidity sensors are usually used to obtain the internal temperature and internal humidity of the fresh-keeping equipment to determine the dew point temperature inside the fresh-keeping equipment, so as to determine the condensation risk and then control the fresh-keeping equipment to

[0063] However, this approach overlooks the problem that the internal temperature of fresh-keeping equipment cannot accurately reflect the temperature of the food itself. This causes some hotter food to maintain strong physiological activity even in a low-temperature environment, making it difficult to remove the moisture around the food in a timely manner. This, in turn, easily leads to condensation on the surface of the food, which is detrimental to food storage. Therefore, how to effectively prevent condensation in fresh-keeping equipment has become an urgent problem that needs to be solved.

[0064] Based on this, the embodiment of the present invention provides an anti-condensation control method, device, equipment and storage medium for a fresh-keeping device. When the fresh-keeping device is turned on, a violent gas exchange occurs between the inside of the box and the outside world, resulting in temperature fluctuations in the internal environment of the box. Therefore, the switch state of the box can be used to determine whether the temperature fluctuation occurs inside the box; and the sensed temperature is obtained by measuring the contact of the food in the box with the temperature measuring component, which can more accurately reflect the temperature and physiological activity intensity of the food itself. In addition, the humidity of the box is a key factor affecting the generation of condensation inside the box. Therefore, the condensation risk of the box can be evaluated by comprehensively considering the switch state of the box, the sensed temperature and the humidity of the box, thereby helping to control the operation of the decondensation device, the deoxygenation device and the compressor of the fresh-keeping device, and accurately reducing the temperature of the food. The deoxygenation device can reduce the oxygen content inside the box to suppress the generation of water vapor in the food. At the same time, the decondensation device can be used to timely discharge the water vapor inside the box, effectively reducing the condensation risk of the fresh-keeping device, which is beneficial to improving the fresh-keeping effect of the fresh-keeping device on the food.

[0065] The embodiments of the present invention are further described below with reference to the accompanying drawings.

[0066] refer to Figure 1 , Figure 1 A schematic structural diagram of a fresh-keeping device provided in one embodiment of the present invention.

[0067] It will be appreciated that in some embodiments of the present invention, the fresh-keeping device 100 includes a housing 900 and a compressor 110. The housing 900 is provided with a control device 700, a switch detection component 500, a temperature measurement component 400, a humidity sensor 600, a decondensation removal device 200, and a deoxygenation device 300 for reducing the oxygen content within the housing. The control device 700 is respectively connected to the switch detection component 500, the temperature measurement component 400, the humidity sensor 600, the decondensation removal device 200, the compressor 110, and the deoxygenation device 300. When the compressor 110 is in operation, the fresh-keeping device 100 continuously delivers low-temperature gas into the housing 900 to lower the temperature inside the housing 900 and cool the food. The temperature of the gas delivered by the fresh-keeping device 100 to the housing 900 can be adjusted by adjusting the operating power of the compressor 110, thereby helping to quickly lower the temperature of the food.

[0068] The switch detection component 500 can detect whether the cabinet 900 of the fresh-keeping device 100 is opened. Specifically, the switch detection component 500 can be a contact measuring device such as a magnetic switch, or a non-contact measuring device such as an infrared detection device. When the fresh-keeping device 100 is a refrigerator, the cabinet 900 can refer to the cold storage room in the refrigerator. Therefore, the switch detection component 500 can be installed on the cabinet 900 and the refrigerator door respectively, so as to detect whether the cabinet door in the refrigerator is opened, and the cabinet switch state detected by the switch detection component 500 is correspondingly represented as the switch state of the cabinet door. In addition, the cabinet 900 can also refer to the fresh-keeping drawer in the refrigerator. Figure 2 , Figure 2 FIG. 1 shows a structural diagram of the fresh-keeping device according to an embodiment of the present invention from another perspective. Figure 2 As shown, the switch detection components 500 can be installed in corresponding positions inside the refrigerator that contact the drawer side walls, thereby detecting whether the fresh-keeping drawer is pulled out. Accordingly, the cabinet switch state detected by the switch detection component 500 represents the closed state of the fresh-keeping drawer. When the cabinet 900 is opened, that is, the cabinet switch state is open, the gas inside the cabinet 900 will exchange with the outside air. During this exchange process, the cabinet humidity and the sensed temperature of the food may be affected. Therefore, the cabinet switch state obtained by the switch detection component 500 can determine whether the gas inside the cabinet 900 is exchanging with the outside air, which helps to more accurately determine whether there is a risk of condensation.

[0069] Reference Figure 3 , Figure 3 FIG. 1 shows a schematic structural diagram of a fresh-keeping device provided by an embodiment of the present invention. Figure 3As shown, the fresh-keeping device can be a refrigerator compartment, and the housing can be a drawer. The temperature measurement assembly 400 includes a heat-conducting assembly 410 disposed at the bottom of the housing 900 and a temperature sensor mounted on the heat-conducting assembly 410. The temperature sensor is in close contact with the heat-conducting assembly 410 and is connected to the control device 700. When food is placed in the housing 900, the food comes into contact with the heat-conducting assembly 410, allowing heat from the food to be transferred to the temperature sensor through the heat-conducting assembly 410. Therefore, the temperature measurement component 400 can perform contact measurement of the food inside the housing 900, obtaining a more accurate food temperature. A higher food temperature indicates a higher level of physiological activity in the food. This physiological activity causes the food to expel moisture, which not only affects the food's freshness but also increases the humidity inside the housing 900, increasing the risk of condensation. Therefore, using accurate food temperature helps control the fresh-keeping device 100, reducing the risk of condensation and improving food preservation. The heat conducting component 410 may be a heat conducting material made of one or more of metal, graphite, and silicon carbide. It should be noted that the heat conducting component 410 may be disposed on a bottom plate at the bottom of the box 900 for supporting food, and the temperature sensor may be located inside the box 900 and below the heat conducting component 410, so that the temperature sensor can accurately measure the food in contact with the food, reduce interference from the external environment, and obtain an accurate sensed temperature. Furthermore, the temperature sensor may be located outside the box 900, thereby avoiding compression of the food storage space within the box 900 and reducing the effect of the low-temperature gas delivered by the fresh-keeping device 100 to the interior of the box 900 being directly blown onto the temperature sensor, thereby affecting the sensed temperature.

[0070] Reference Figure 4 , Figure 4 A schematic diagram of the structure of the fresh-keeping device according to an embodiment of the present invention from another perspective is shown. A humidity sensor 600 is disposed on the side of the condensation removal device 200 near the housing 900. The humidity sensor 600 is capable of detecting the humidity within the housing. The higher the humidity within the fresh-keeping device 100, the more likely condensation will form within the housing 900. This indicates a higher risk of condensation within the housing 900, which is detrimental to food preservation. Therefore, the condensation risk within the housing 900 can be determined by detecting the humidity within the housing 900.

[0071] It should be noted that the positions and quantities of the humidity sensor 600 and the temperature measuring component 400 in the box body 900 can be adjusted according to actual usage. For example, when the fresh-keeping device 100 is a drawer, the temperature measuring component 400 can be set at the bottom of the drawer, and the humidity sensor 600 can be set on the inner wall of the drawer; for another example, when the fresh-keeping device 100 is a refrigerated transport vehicle, due to the large internal volume of the fresh-keeping device 100, the temperature measuring component 400 can be provided in multiple groups and evenly installed at the bottom of the freezer of the refrigerated transport vehicle to improve the accuracy of measuring the sensed temperature; and the humidity sensor 600 can be provided in multiple groups and evenly distributed on the four sides of the freezer of the refrigerated transport vehicle to improve the accuracy of measuring the humidity of the box body.

[0072] Reference Figure 5 , Figure 5 A schematic structural diagram of a fresh-keeping device according to an embodiment of the present invention is shown from another perspective. The condensation removal device 200 includes a fan and an extension tube 210. The fan includes a first air outlet and a second air outlet. The first air outlet is used to connect to the interior of the housing 900, and the second air outlet is used to connect to the external environment. Therefore, the fan can exchange high-humidity gas within the housing 900 with low-humidity gas from the outside. The connection area of ​​the first air outlet is less than or equal to the connection area of ​​the second air outlet. When the connection area of ​​the first air outlet is smaller than the connection area of ​​the second air outlet, it helps control the speed of humidity exchange, avoiding condensation caused by excessive temperature and humidity changes due to rapid gas exchange, achieving stable regulation of the housing humidity, and improving the humidity regulation effect of the condensation removal device 200. One end of the extension tube 210 is connected to the second air outlet, and the other end of the extension tube 210 faces the outside of the housing 900. This effectively prevents gas backflow, ensures that the gas inside the housing 900 can be smoothly discharged to the outside of the housing 900, and improves the condensation removal efficiency of the condensation removal device 200.

[0073] Reference Figure 3 The deoxygenation device 300 can be installed on the top of the box 900. The deoxygenation device 300 can reduce the oxygen content inside the box 900, thereby creating a low-oxygen environment that is conducive to food preservation, inhibiting the physiological activity of food, reducing water vapor generation, and thus helping to reduce the risk of condensation inside the preservation equipment 100.

[0074] Therefore, during the operation of the fresh-keeping device 100, the control device 700 can accurately measure the parameters that affect the fresh-keeping of food through the switch detection component 500 and the temperature measurement component 400, thereby helping to determine the fresh-keeping environment state inside the box 900, and then accurately controlling the decondensation removal device 200, the deoxygenation device 300, and the compressor 110 inside the fresh-keeping device, thereby improving the fresh-keeping performance of the fresh-keeping device 100 and improving the fresh-keeping effect on food. It should be noted that the fresh-keeping device 100 can be a drawer, a refrigerator, a freezer, or a refrigerated transport vehicle, which is not specifically limited in the present invention.

[0080] Step S200, controlling the operation of the compressors of the decondensation removal device, the deoxygenation device and the fresh-keeping equipment according to the cabinet switch state, the sensed temperature and the cabinet humidity.

[0081] It is understandable that the cabinet switch state can be expressed as whether the cabinet is opened, and the cabinet switch state includes an open state and a closed state. When the cabinet switch state is in the open state, it can be considered that the cabinet of the fresh-keeping equipment is opened, and the gas inside the cabinet will be violently exchanged with the external gas, causing the temperature and humidity inside the cabinet to change, thereby affecting the physiological activities of the food in the cabinet and the generation of condensation in the cabinet. When the cabinet switch state is in the closed state, it can be considered that the internal environment of the cabinet of the current fresh-keeping equipment is closed and difficult to directly exchange with the external gas. At this time, the sensed temperature and cabinet humidity are not easily affected by the external environment. Therefore, the cabinet switch state can be used to determine whether the gas in the cabinet is exchanged with the external gas, which helps to determine the condensation risk inside the cabinet.

[0082] When the cabinet humidity is higher, the temperature required to cool the air to saturation is lower, and condensation is more likely to form inside the cabinet, i.e., the condensation risk inside the cabinet is higher. Specifically, the condensation risk inside the cabinet can be determined by determining whether the cabinet humidity exceeds a preset humidity threshold. For example, when the cabinet humidity exceeds the preset humidity threshold, the condensation risk inside the cabinet can be considered high. The degree of condensation risk inside the cabinet can be determined based on the difference between the cabinet humidity and the preset humidity threshold.

[0083] The sensed temperature obtained from contact measurement of food can accurately reflect the intensity of the food's physiological activity. Since the physiological activity of the food will cause the food to discharge water vapor to the outside, the higher the sensed temperature, the higher the intensity of the food's physiological activity, the more water vapor is generated, resulting in increased humidity in the box, and thus increasing the risk of condensation inside the box; the lower the sensed temperature, the more it can be considered that the physiological activity of the food is suppressed, reducing water vapor generation, which is beneficial to reducing the risk of condensation inside the box.

[0084] Since different cabinet switch states have an impact on the changes in both the sensed temperature and the cabinet humidity, and different sensed temperatures have different effects on the cabinet humidity, and cabinet humidity is an important factor affecting the condensation risk of the cabinet, the condensation risk of the cabinet can be accurately judged by comprehensively considering the cabinet switch state, the sensed temperature and cabinet humidity. Compared with the solution in the related art that uses the temperature and humidity inside the fresh-keeping equipment to judge the condensation risk, the anti-condensation control method provided by the embodiment of the present invention introduces the cabinet switch state and the sensed temperature, and makes a comprehensive judgment on the condensation risk in combination with the cabinet humidity. It can take into account the impact of different cabinet switch states on the temperature and humidity inside the fresh-keeping equipment and the sensed temperature of the food, as well as the problem of different physiological activity intensities of the food itself at different sensed temperatures, thereby achieving a more accurate judgment of the condensation risk of the cabinet.

[0085] The decondensation device exchanges the high-humidity gas in the box with the low-humidity gas outside through a fan, thereby reducing the humidity of the box and reducing the risk of condensation in the box. The deoxygenation device is used to reduce the oxygen content in the box. By reducing the oxygen content in the box, the physiological effects of the food can be suppressed, thereby reducing the water loss and organic matter consumption of the food. During the operation of the compressor, low-temperature gas can be transported into the box, which can reduce the ambient temperature in the box and the sensed temperature of the food. The operating power of the compressor can be adjusted to adjust the temperature change rate of both the ambient temperature and the sensed temperature, thereby achieving rapid cooling of the food.

[0086] It can be understood that the embodiment of the present invention can more accurately judge the condensation risk of the fresh-keeping equipment by obtaining the cabinet switch status, sensing temperature and cabinet temperature, and using the cabinet switch status, sensing temperature and cabinet humidity, so as to more accurately control the working status of the decondensation device, the deoxygenation device and the compressor. It can accurately lower the temperature of the food and reduce the oxygen content inside the cabinet through the deoxygenation device to inhibit the food from generating water vapor. At the same time, the water vapor inside the cabinet is discharged in time through the decondensation device, which effectively reduces the condensation risk of the fresh-keeping equipment and is beneficial to improving the fresh-keeping effect of the fresh-keeping equipment on the food.

[0087] It should be noted that when condensation occurs inside the box, it may accelerate the spoilage of food and cause parts inside the box to rust and damage, thereby reducing the box's freshness preservation performance, that is, interfering with the box's condensation removal efficiency, resulting in an increased condensation risk in the box.

[0088] It is understood that the food ingredients are vegetables or fruits, and their physiological activities include transpiration and respiration. When the food ingredients undergo transpiration, they consume the water within the food ingredients, causing the water content to decrease. Furthermore, the water expelled from the food ingredients into the box increases the humidity within the box, increasing the risk of condensation. When the food ingredients undergo respiration, they consume the organic matter within the food ingredients, accelerating their spoilage and hindering their storage. When the fresh-keeping device is opened, the air inside the box undergoes a vigorous exchange with the air outside. If high-humidity and high-temperature air from the outside enters the box, it not only increases the humidity within the box and the ambient temperature within the box, but also intensifies the transpiration or respiration of the food ingredients, generating large amounts of water vapor, thereby increasing the risk of condensation. Therefore, the control device can determine the current condensation risk of the box by obtaining the box switch status, sensing the temperature, and the box humidity. This helps control the operation of the decondensation device, deoxygenator, and compressor to reduce the risk of condensation. Among them, by controlling the operation of the decondensation device, condensation caused by high humidity in the box can be avoided; and by controlling the operation of the deoxygenation device and the compressor, the oxygen content in the box and the sensed temperature can be reduced, thereby inhibiting the transpiration and respiration of the food, thereby reducing the risk of condensation.

[0089] Reference Figure 7 , Figure 7 This is a specific flow chart for controlling the operation of the fresh-keeping device provided by an embodiment of the present invention, including but not limited to the following steps:

[0090] Step S210, controlling the operation mode of the fresh-keeping device according to the cabinet switch state and cabinet humidity;

[0091] In step S220, when the fresh-keeping device operates in the first anti-condensation mode, the decondensation device, the deoxygenation device and the compressor of the fresh-keeping device are controlled to operate according to the sensed temperature.

[0092] It's understandable that when the cabinet is closed, the humidity primarily comes from water vapor generated by the physiological activity of the food, resulting in a lower risk of condensation. However, when the cabinet is open, the air inside the cabinet exchanges with the outside air, potentially causing a change in the humidity, making the cabinet susceptible to condensation risk. The cabinet's open or closed state can be used to determine whether the cabinet is open or closed, and thus whether the air inside the cabinet is exchanging air with the outside air. Higher cabinet humidity results in lower temperatures required for air cooling to reach saturation, making condensation more likely to form inside the cabinet, thus increasing the risk of condensation inside the cabinet. Therefore, the cabinet's open or closed state and humidity can effectively determine the condensation risk. When condensation risk exists within the cabinet, the fresh-keeping equipment can be controlled to switch from normal cooling mode to anti-condensation mode to reduce the risk. It should be noted that when the cabinet is open, high-humidity air from the outside exchanges with low-humidity air inside the cabinet, potentially causing an increase in humidity, a rise in the sensed temperature, or an increase in oxygen content. In these cases, normal cooling mode cannot guarantee fresh-keeping effectiveness. In anti-condensation mode, the control device controls the operating states of the decondensation device, deoxygenator, and compressor based on different parameters to reduce the risk of condensation in the fresh-keeping equipment. The decondensation device exchanges the high-humidity air inside the box with the low-humidity air outside, reducing the humidity of the box and, in turn, the risk of condensation. By adjusting the operating state of the compressor to regulate the rate of change of both the ambient temperature and the sensed temperature, the food can be quickly cooled. The deoxygenator can reduce the oxygen content in the box, thereby inhibiting the physiological activity of the food.

[0093] It can be understood that when the fresh-keeping equipment operates in the first anti-condensation mode, the control device will control the operation of the decondensation device, the deoxygenation device and the compressor according to the sensed temperature to reduce the condensation risk of the fresh-keeping equipment. For example, when the sensed temperature is higher than the preset temperature, the control device can change the operating power of the compressor to make the compressor output gas with a lower temperature to quickly cool the food. The control device can also control the deoxygenation device to work to reduce the oxygen content in the box.

[0094] It should be noted that when the fresh-keeping equipment is in normal refrigeration mode, the decondensation device and the deoxygenation device are in the stopped state, and the compressor continuously outputs low-temperature gas at rated power to maintain the ambient temperature in the box, thereby maintaining the sensed temperature of the food.

[0095] It can be understood that the control device obtains the box switch status, box humidity and sensed temperature in real time, and then controls the preservation equipment to operate different anti-condensation modes according to the box switch status and box humidity. By obtaining relevant parameters in real time, the operation mode of the preservation equipment can be adjusted in time to reduce the condensation risk in time.

[0096] It is understandable that the control device will obtain the cabinet humidity and sense the temperature after obtaining the cabinet switch status for a preset period of time, and then control the fresh-keeping equipment to run different anti-condensation modes according to the cabinet switch status and the cabinet humidity. It should be noted that when the cabinet is opened, due to the different pressures inside and outside the cabinet, high-humidity gas or low-humidity gas may surround the humidity sensor, causing the humidity sensor to misjudge the cabinet humidity, and then cause the fresh-keeping equipment to run in the wrong anti-condensation mode.

[0097] Reference Figure 8 , Figure 8 This is a specific flow chart of controlling the fresh-keeping device to operate in the first anti-condensation mode provided by an embodiment of the present invention, including but not limited to the following steps:

[0098] Step S230: When the cabinet switch state is on and the cabinet humidity is lower than a preset humidity threshold, the fresh-keeping device is controlled to operate in the first anti-condensation mode.

[0099] It is understood that when the cabinet switch is in the on state and the cabinet humidity is below the preset humidity threshold, it indicates that after the fresh-keeping device is turned on, the low-temperature gas inside the cabinet is vigorously exchanged with the high-temperature gas outside. Since the humidity of the air outside the cabinet is lower than or equal to the humidity of the air inside the cabinet, the humidity inside the cabinet is lower than the preset humidity threshold. When the cabinet humidity exceeds the preset humidity threshold, it can be considered that the risk of condensation inside the cabinet is high. Although the humidity inside the cabinet is lower than the preset humidity threshold, the process of exchanging gas inside the cabinet with the outside air may cause the ambient temperature inside the cabinet to rise, causing the sensed temperature of the food to rise, exacerbating the physiological activity of the food, causing the food to release more water vapor, and thus causing the humidity inside the cabinet to rise. Therefore, when the cabinet switch is in the on state and the cabinet humidity is below the preset humidity threshold, the fresh-keeping device is controlled to operate in the first anti-condensation mode. The control device controls the operating states of the decondensation device, the deoxygenator, and the compressor according to the sensed temperature to reduce the ambient temperature of the cabinet, thereby reducing the sensed temperature of the food and suppressing the physiological activity of the food.

[0100] It should be noted that when the fresh-keeping equipment operates in the first anti-condensation mode, when the sensed temperature exceeds a preset temperature threshold, the control device controls the compressor to operate at high power to lower the ambient temperature of the cabinet, thereby lowering the sensed temperature of the food, so that the sensed temperature is below the preset temperature threshold. The higher the temperature of the food, the more active its physiological activity, and the shorter its shelf life. Failure to cool the food in a timely manner may accelerate its spoilage. In addition, while the control device controls the compressor to operate at high power, it also controls the decondensation device to maintain its current operating state to maintain the humidity of the cabinet.

[0101] It is understandable that when the sensed temperature is lower than the preset temperature threshold, the control device will also control the deoxygenation device to work to reduce the oxygen content in the box, thereby inhibiting the physiological activity of the food.

[0102] It should be noted that high-power operation of the compressor means that the compressor operates at a higher power than before the fresh-keeping device is turned on, thereby improving the cooling effect of the cabinet. For example, if the operating power of the compressor before the fresh-keeping device is turned on is 500W, the operating power of the compressor during high-power operation can be 600W. The specific power parameter can be set according to actual usage and is not specifically limited in the present invention.

[0103] It should be noted that when the box switch state is in the open state and the box humidity is lower than the preset humidity threshold, that is, the execution conditions for controlling the fresh-keeping equipment to operate in the first anti-condensation mode are met, the current operation mode of the fresh-keeping equipment can be maintained, and after the box switch state is switched from the open state to the closed state, the operation mode of the fresh-keeping equipment is switched to the first anti-condensation mode, that is, the working states of the decondensation device, the deoxygenation device and the compressor are controlled respectively according to the sensed temperature to avoid the decondensation device, the deoxygenation device and the compressor of the fresh-keeping equipment working during the operation, while the gas in the box continues to be exchanged with the outside world, causing the fresh-keeping equipment to work in the first anti-condensation mode for a long time.

[0104] It is understandable that when the fresh-keeping device is running in the first anti-condensation mode, the control device will continue to obtain the sensed temperature. When the sensed temperature is lower than the preset temperature threshold, the control device controls the fresh-keeping device to stop running in the first anti-condensation mode.

[0105] Reference Figure 9 , Figure 9 This is a specific flow chart for controlling the operation of the fresh-keeping device provided by an embodiment of the present invention, including but not limited to the following steps:

[0106] Step S250: When the cabinet switch state is on and the cabinet humidity is higher than or equal to the preset humidity threshold, the fresh-keeping device is controlled to operate in the first anti-condensation mode.

[0107] It can be understood that when the cabinet switch state is on and the cabinet humidity is higher than or equal to the preset humidity threshold, it means that after the fresh-keeping device is turned on, the low-humidity gas inside the cabinet and the high-humidity gas outside are violently exchanged, causing the cabinet humidity to rise. The control device can also control the fresh-keeping device to operate in the first anti-condensation mode, and control the decondensation device, deoxygenation device and compressor working status according to the sensed temperature to lower the ambient temperature of the cabinet, and then lower the sensed temperature of the food, so as to inhibit the physiological activity of the food and avoid further increase in the humidity in the cabinet due to the physiological activity of the food.

[0108] Reference Figure 9 , Figure 9 This is a specific flow chart for controlling the operation of the fresh-keeping device provided by an embodiment of the present invention, including but not limited to the following steps:

[0109] Step S251: When the cabinet switch state is on and the cabinet humidity is higher than or equal to a preset humidity threshold, the fresh-keeping device is controlled to operate in the second anti-condensation mode.

[0110] It is understood that when the cabinet switch is in the on state and the cabinet humidity is higher than or equal to the preset humidity threshold, it means that after the fresh-keeping device is turned on, the low-humidity air inside the cabinet and the high-humidity air outside are vigorously exchanged, causing the cabinet humidity to rise. Therefore, when the cabinet switch is in the on state and the cabinet humidity is higher than or equal to the preset humidity threshold, the fresh-keeping device is controlled to operate in the second anti-condensation mode. The control device controls the decondensation device, deoxygenation device, and compressor to operate according to the sensed temperature and cabinet humidity to reduce the cabinet humidity to the preset humidity threshold.

[0111] It should be noted that when the fresh-keeping equipment runs the second anti-condensation mode, the sensed temperature of the food is still lower than the preset temperature threshold. At this time, the control device only changes the working state of the decondensation device according to the humidity of the box to reduce the humidity of the box and reduce the risk of condensation in the box.

[0112] It should be noted that high humidity inside the cabinet not only increases the risk of condensation but also promotes the physiological activity of food, reducing the preservation effectiveness of the fresh-keeping equipment. In the second anti-condensation mode, the control device controls the decondensation device to exchange the high-humidity air inside the cabinet with low-humidity air from the outside to reduce the cabinet's humidity and prevent condensation from forming inside the cabinet due to excessive humidity. The control device also controls the compressor to operate at high power to cool the food, keeping the sensed temperature below a preset threshold.

[0113] It can be understood that when the fresh-keeping equipment operates in the second anti-condensation mode, the humidity of the cabinet is reduced to a preset humidity threshold. The control device can control the fresh-keeping equipment to switch to the first anti-condensation mode, and then control the operation of the decondensation device, deoxygenation device and the compressor of the fresh-keeping equipment according to the sensed temperature.

[0114] It should be noted that when the box switch state is in the on state and the box humidity is higher than or equal to the preset humidity threshold, that is, the execution conditions for controlling the fresh-keeping equipment to operate in the second anti-condensation mode are met, the current operation mode of the fresh-keeping equipment can be maintained, and after the box switch state is switched from the on state to the off state, the operation mode of the fresh-keeping equipment is switched to the second anti-condensation mode, that is, the working states of the decondensation device, the deoxygenation device and the compressor are controlled respectively according to the sensed temperature and the box humidity, so as to avoid the decondensation device, the deoxygenation device and the compressor of the fresh-keeping equipment from continuing to exchange gas in the box with the outside world during operation, resulting in the fresh-keeping equipment operating in the second anti-condensation mode for a long time.

[0115] It is understandable that when the sensed temperature is lower than the preset temperature threshold, the control device will also control the deoxygenation device to work to reduce the oxygen content in the box, thereby inhibiting the physiological activity of the food.

[0116] Reference Figure 10 , Figure 10 This is a specific flow chart of controlling the operation of a fresh-keeping device according to a sensed temperature provided by an embodiment of the present invention, including but not limited to the following steps:

[0117] Step S300, controlling the operation of the compressors of the decondensation removal device and the fresh-keeping equipment;

[0118] Step S310: When the sensed temperature is lower than a preset temperature threshold, the deoxygenation device is controlled to operate.

[0119] It is understood that the control device controls the decondensation device to lower the humidity of the cabinet, causing it to fall below a preset humidity threshold. The control device also controls the compressor to cool the food inside the cabinet, causing the food's sensed temperature to fall below a preset temperature threshold. When the sensed temperature falls below the preset temperature threshold, the control device controls the deoxygenation device to operate, reducing the oxygen content in the cabinet. It should be noted that in a low-temperature, low-oxygen environment, the physiological activity of food is suppressed, effectively extending the storage time of the food.

[0120] Reference Figure 11 , Figure 11 This is a specific flow chart of the fresh-keeping device provided by an embodiment of the present invention operating in the second anti-condensation mode, including but not limited to the following steps:

[0121] Step S240: When the fresh-keeping device operates in the second anti-condensation mode, the decondensation device, the deoxygenation device and the compressor of the fresh-keeping device are controlled to operate according to the sensed temperature and the cabinet humidity.

[0122] It is understandable that when the first anti-condensation mode cannot cope with the current condensation risk of the fresh-keeping device, the fresh-keeping device will operate the second anti-condensation mode to reduce the condensation risk of the fresh-keeping device. When the fresh-keeping device operates in the second anti-condensation mode, the control device controls the operation of the decondensation device, the deoxygenation device, and the compressor according to the sensed temperature and the humidity of the cabinet to reduce the humidity of the cabinet, the sensed temperature of the food, and the oxygen content in the cabinet. For example, the control device can control the decondensation device to operate to reduce the humidity of the cabinet; control the compressor to change the operating power so that the compressor outputs gas with a lower temperature to reduce the ambient temperature in the cabinet, thereby reducing the sensed temperature of the food. The control device can also control the deoxygenation device to operate to reduce the oxygen content in the cabinet.

[0123] Reference Figure 12 , Figure 12 This is a specific flow chart of controlling the operation of the fresh-keeping device according to the sensed temperature and cabinet humidity provided by an embodiment of the present invention, including but not limited to the following steps:

[0124] Step S320: When the sensed temperature is lower than the preset temperature and the humidity of the box is lower than the preset humidity threshold, the deoxygenation device is controlled to operate.

[0125] It is understandable that the control device controls the operation of the decondensation device and the compressor. When the sensed temperature is lower than the preset temperature and the cabinet humidity is lower than the preset humidity threshold, the control device controls the operation of the deoxygenation device. When the deoxygenation device starts to operate, the air pressure in the cabinet will decrease as the oxygen decreases. When the humidity and temperature remain unchanged, the lower the air pressure, the lower the dew point. Therefore, before deoxygenating the cabinet, the sensed temperature of the food is reduced to the preset temperature threshold through the compressor and the cabinet humidity is reduced to the preset humidity threshold through the decondensation device. This can avoid condensation in the cabinet due to the decrease in the dew point in the cabinet during the process of decreasing air pressure.

[0126] Reference Figure 13 , Figure 13 This is a specific flow chart of controlling the fresh-keeping device to operate in the third anti-condensation mode provided by an embodiment of the present invention, including but not limited to the following steps:

[0127] Step S260: When the fresh-keeping device operates in the third anti-condensation mode, the decondensation removal device is controlled to operate according to the humidity of the cabinet.

[0128] It is understood that the control device obtains the cabinet's switch status, senses the temperature and cabinet humidity, determines the cabinet's condensation risk based on the cabinet's switch status and humidity, and then controls the fresh-keeping equipment's operating mode based on the condensation risk to reduce the risk of condensation within the cabinet. Fresh-keeping equipment has multiple different operating modes. In each operating mode, the control device controls the operating status of the decondensation removal device, deoxygenation device, and compressor based on different parameters. When the fresh-keeping equipment operates in the third anti-condensation mode, the control device controls the operation of the decondensation removal device, deoxygenation device, and compressor based on the cabinet humidity.

[0129] It should be noted that when the fresh-keeping device operates in the first anti-condensation mode, it means that after the cabinet is opened, the cabinet humidity does not change or the cabinet humidity after the change is still lower than the preset humidity threshold, but the sensed temperature of the food may change due to gas exchange, thereby affecting the physiological activity of the food. Therefore, in the first anti-condensation mode, the control device controls the working states of the decondensation device, the deoxygenation device and the compressor according to the sensed temperature, so that the sensed temperature of the food is lower than the preset temperature threshold, so as to suppress the physiological activity of the food. When the fresh-keeping device operates in the second anti-condensation mode, it means that the cabinet humidity is higher than the preset humidity threshold. At this time, the risk of condensation in the cabinet is high and the sensed temperature of the food may also change. Therefore, in the second anti-condensation mode, the control device controls the working states of the decondensation device, the deoxygenation device and the compressor according to the sensed temperature and the cabinet humidity, so that the sensed temperature of the food is lower than the preset temperature threshold and the cabinet humidity is lower than the preset humidity threshold. When the fresh-keeping equipment operates in the third anti-condensation state, it means that the humidity in the box may rise due to the water vapor generated by the physiological activities of the food. At this time, the risk of condensation in the box is high, but the box is always in a closed state, and the sensed temperature of the food may not change. Therefore, in the third anti-condensation mode, the control device controls the working states of the decondensation device, the deoxygenation device and the compressor according to the humidity of the box, so that the humidity of the box is lower than the preset humidity threshold.

[0130] Reference Figure 14 , Figure 14 This is a specific flow chart of controlling the fresh-keeping device to operate in the third anti-condensation mode provided by an embodiment of the present invention, including but not limited to the following steps:

[0131] Step S270: When the cabinet switch state is closed and the cabinet humidity is higher than or equal to the preset humidity threshold, the fresh-keeping device is controlled to operate in the third anti-condensation mode.

[0132] It is understood that when the cabinet switch is closed and the cabinet humidity is higher than or equal to the preset humidity threshold, the control device controls the fresh-keeping device to operate in the third anti-condensation mode. At this time, the control device controls the decondensation removal device in the cabinet to open, exchanging the high-humidity air in the cabinet with the low-humidity air outside, thereby reducing the cabinet humidity. It should be noted that when the cabinet is closed, the physiological activities of the food in the cabinet will also produce moisture, causing the cabinet humidity to rise. If the moisture in the cabinet cannot be discharged in time, the cabinet humidity may rise, thereby increasing the risk of condensation in the cabinet.

[0133] It should be noted that when the humidity in the box is lower than the preset humidity threshold, the control device controls the deoxygenation device to turn on, reducing the oxygen content in the box and further inhibiting the physiological effects of the food.

[0134] It should be noted that when the dew removal device is turned on, the control device will continue to detect the humidity of the box. When the humidity of the box is lower than the preset humidity threshold, the control device controls the dew removal device to be turned off.

[0135] refer to Figure 15 , Figure 15 A structural diagram of an operation control device 1500 is provided for an embodiment of the second aspect of the present invention, wherein the operation control device 1500 includes: a memory 1510, a processor 1520, and a computer program stored in the memory 1510 and executable on the processor 1520. When the processor 1520 executes the computer program, it implements the anti-condensation method of the fresh-keeping equipment in the above-mentioned embodiment.

[0136] Memory 1510, as a non-transitory computer-readable storage medium, can be used to store non-transitory software programs and non-transitory computer-executable programs, such as the air conditioner control method in the above-mentioned embodiment of the present invention. Processor 1520 implements the anti-condensation method for the fresh-keeping device in the above-mentioned embodiment of the present invention by executing the non-transitory software program and instructions stored in memory 1510.

[0137] The memory 1510 may include a program storage area and a data storage area, wherein the program storage area may store an operating system and application programs required for at least one function; the data storage area may store data required to execute the anti-condensation method of the fresh-keeping device in the above embodiment, etc. In addition, the memory 1510 may include a high-speed random access memory 1510, and may also include a non-volatile memory 1510, such as at least one disk storage device, a flash memory device, or other non-volatile solid-state storage device. It should be noted that the memory 1510 may optionally include a memory 1510 remotely located relative to the processor 1520, and these remote memories 1510 may be connected to the terminal via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0138] The non-transient software program and instructions required to implement the anti-condensation method of the fresh-keeping device in the above embodiment are stored in the memory. When executed by one or more processors, the anti-condensation method of the fresh-keeping device in the above embodiment is executed, for example, the above-described Figure 6 Steps S100 to S200 of the method, Figure 7 Steps S210 to S220 of the method, Figure 8 Step S230 of the method, Figure 9 Method steps S250 and S251, Figure 10 Steps S300 to S310 of the method, Figure 11 Method step S240, Figure 12 Method step S320, Figure 13 Method step S260 and Figure 14 Method step S270 in .

[0139] The third aspect of the present invention provides a fresh-keeping device, which includes an operation control device 1400 as provided in the second aspect of the embodiment. Therefore, when the fresh-keeping device is turned on, a violent gas exchange occurs between the inside of the box and the outside world, resulting in temperature fluctuations in the internal environment of the box. Therefore, whether the temperature fluctuation occurs inside the box can be judged by the box switch state; and the sensed temperature is obtained by measuring the contact between the temperature measuring component and the food in the box, which can more accurately reflect the temperature and physiological activity intensity of the food itself. Therefore, the box switch state, sensed temperature and box humidity can be used to comprehensively evaluate the condensation risk of the box, so that the operation of the decondensation device, deoxygenation device and compressor of the fresh-keeping device can be accurately controlled, so that the temperature of the food can be lowered more accurately, and the deoxygenation device can be controlled in time to reduce the oxygen content inside the box, effectively inhibiting the food from generating water vapor. At the same time, the decondensation device is used to timely remove water vapor in the box, thereby effectively reducing the condensation risk of the fresh-keeping device and helping to improve the fresh-keeping effect of the fresh-keeping device.

[0140] A fourth embodiment of the present invention provides a fresh-keeping device, referring to Figure 2 、 Figure 3 、 Figure 4 or Figure 5 The fresh-keeping device 100 includes a box body 900, a decondensation device 200, a deoxygenation device 300, and a switch detection component 500. The fresh-keeping device 100 is provided with a storage cavity, and the box body 900 is arranged in the storage cavity. A protrusion for moving the box body 900 is provided on the side of the box body 900 away from the storage cavity. The user can use the protrusion to pull the box body 900 out of the storage cavity or push the box body 900 into the storage cavity. A temperature measuring component is provided in the box body 900. The temperature measuring component includes a temperature sensor and a heat conducting component 410 installed at the bottom of the box body 900. The temperature sensor is installed on the side of the heat conducting component 410 close to the storage cavity. When food is placed in the box body 900, the heat of the food can be transferred to the temperature sensor through the heat conducting component 410. The decondensation device 200 is installed in the storage cavity and is used to separate the high-humidity gas in the box body 900 from the low-humidity gas outside. The deoxygenation device 300 is installed on the top of the accommodating chamber and is used to extract oxygen from the box body 900 to reduce the oxygen content in the box body 900. The humidity sensor 600 is arranged on a side of the decondensation removal device 200 close to the box body 900.

[0141] It should be noted that the heat conducting component 410 may be a heat conducting material made of one or more of metal materials, graphite and silicon carbide.

[0142] It is understood that the dehumidification device 200 includes a fan and an extension tube 210. The fan includes a first air outlet and a second air outlet. The first air outlet is used to connect to the interior of the housing 900, and the second air outlet is used to connect to the external environment. Therefore, the fan can exchange high-humidity gas in the housing 900 with low-humidity gas from the outside. The connection area of ​​the first air outlet is less than or equal to the connection area of ​​the second air outlet. When the connection area of ​​the first air outlet is smaller than the connection area of ​​the second air outlet, it helps to control the speed of humidity exchange, avoid rapid gas exchange resulting in excessive temperature and humidity change rates and condensation, achieve stable regulation of the housing humidity, and improve the humidity regulation effect of the dehumidification device. One end of the extension tube 210 is connected to the second air outlet, and the other end of the extension tube 210 is directed to the outside of the housing 900. This can effectively prevent gas backflow, ensure that the gas inside the housing 900 can be smoothly discharged to the outside of the housing 900, and improve the dehumidification efficiency of the dehumidification device 200.

[0143] It can be understood that the switch detection component 500 can be a magnetic switch detection component or an infrared switch detection component. When the switch detection component is a magnetic switch detection component, a magnetic detection device is provided in the accommodating cavity, the magnetic detection device is connected to the operation control device, and a magnetic part corresponding to the magnetic detection device is provided on the box 900. When the box 900 is in the accommodating cavity, the magnetic part contacts the magnetic detection device, and the magnetic detection device sends a high-level signal to the operation control device. When the box 900 is pulled out of the accommodating cavity, the magnetic part is separated from the magnetic detection device, and the magnetic detection device sends a low-level signal to the operation control device. The operation control device can judge the switch state of the box 900 according to different level signals.
