However, some food such as fruits and vegetables continuously produce water vapor under the action of physiological activities, which increases the humidity inside the fresh-keeping equipment. Therefore, when the temperature inside the fresh-keeping equipment fluctuates, such as when the fresh-keeping equipment cools down food that is higher than the temperature inside the equipment, condensation will be generated inside the fresh-keeping equipment with high humidity, and condensation will not only affect the user experience, but also affect the fresh-keeping effect of 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 cannot be understood as a limitation on the scope of protection of the present invention.

If there is a description of the first and the second, it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0059] It should be noted that the terms such as setting, installing, and connecting in the embodiments of the present invention should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the embodiments of the present invention in combination with the specific content of the technical solution. For example, the term "connection" can be a mechanical connection, an electrical connection, or mutual communication; it can be directly connected or indirectly connected through an intermediate medium.

[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, connecting, etc. 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 will also accelerate the decay of food, affecting the fresh-keeping effect of the fresh-keeping equipment on food. In the related art, 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.

[0063] However, the problem that the internal temperature of the fresh-keeping equipment cannot accurately reflect the temperature of the food itself is ignored, which makes some food with higher temperature still have strong physiological activities in the low temperature environment. The water vapor generated around the food is difficult to remove in time, and condensation is easy to form on the surface of the food, which is not conducive to food storage. Therefore, how to effectively suppress condensation in fresh-keeping equipment has become an urgent problem 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, there is a violent gas exchange between the inside of the box and the outside world, resulting in temperature fluctuations in the internal environment of the box. Therefore, it is possible to determine whether the temperature fluctuation occurs inside the box through the box switch state; and the sensed temperature is obtained by measuring the contact of the food in the box with the temperature measurement 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, so the condensation risk of the box can be evaluated by comprehensively considering the box switch state, the sensed temperature and the box humidity, which is helpful to control the operation of the compressor of the decondensation device, the deoxygenation device and the fresh-keeping device, which can accurately reduce the temperature of the food, and reduce the oxygen content inside the box through the deoxygenation device to inhibit the food from generating water vapor. At the same time, the water vapor inside the box is discharged in time through the decondensation device, which effectively reduces the condensation risk of the fresh-keeping device and is conducive 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 in conjunction with 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 is understood that in some embodiments of the present invention, the fresh-keeping device 100 includes a box 900 and a compressor 110, and the box 900 is provided with a control device 700, a switch detection component 500, a temperature measurement component 400, a humidity sensor 600, a decondensation device 200, and a deoxygenation device 300 for reducing the oxygen content in the box, and the control device 700 is respectively connected to the switch detection component 500, the temperature measurement component 400, the humidity sensor 600, the decondensation device 200, the compressor 110, and the deoxygenation device 300. Among them, when the compressor 110 is in the working state, the fresh-keeping device 100 will continue to transport low-temperature gas into the box 900 to reduce the temperature inside the box 900 and cool the food. Among them, the temperature of the gas transported by the fresh-keeping device 100 to the box 900 can be adjusted by adjusting the operating power of the compressor 110, so as to help quickly reduce the temperature of the food.

[0068] The switch detection component 500 can detect whether the box 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 box 900 can refer to the cold storage room in the refrigerator, so the switch detection component 500 can be installed on the box 900 and the refrigerator door respectively, so as to detect whether the refrigerator door is opened, and the box switch state detected by the switch detection component 500 is correspondingly characterized as the switch state of the door; in addition, the box 900 can also refer to the fresh-keeping drawer in the refrigerator, refer to Figure 2 , Figure 2 FIG. 2 shows a schematic diagram of the structure of the fresh-keeping device according to an embodiment of the present invention from another perspective. Figure 2 As shown, the switch detection component 500 can be installed at the position in contact with the drawer side wall inside the refrigerator, so as to detect 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 in the open state, the gas in the cabinet 900 will be exchanged with the outside air. During the 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 in the cabinet 900 is exchanged with the outside air, which helps to more accurately determine whether there is a risk of condensation.

[0069] Reference Figure 3 , Figure 3 FIG. 2 shows a schematic diagram of the structure of a fresh-keeping device provided by an embodiment of the present invention. Figure 3As shown, the fresh-keeping device can be a cold storage room in a refrigerator, and the box can be a drawer. The temperature measuring component 400 includes a heat conducting component 410 arranged at the bottom of the box 900 and a temperature sensor installed on the heat conducting component 410, the temperature sensor is close to the heat conducting component 410, and the temperature sensor is connected to the control device 700. When the food is placed in the box 900, the food is in contact with the heat conducting component 410, so that the heat of the food can be transferred to the temperature sensor through the heat conducting component 410. Therefore, the food in the box 900 can be contacted and measured by the temperature measuring component 400 to obtain a more accurate food temperature. The higher the temperature of the food, the higher the physiological activity intensity of the food itself. The physiological activity of the food will discharge its own moisture, which is not only not conducive to the preservation of the food, but also increases the humidity inside the box 900 and increases the risk of condensation. Therefore, using accurate food temperature helps to control the fresh-keeping device 100, reduce the risk of condensation, and improve the preservation effect of food. The heat conducting component 410 may be a heat conducting material made of one or more of metal materials, graphite and silicon carbide. It should be noted that the heat conducting component 410 may be arranged on a bottom plate for supporting food at the bottom of the box 900, 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 contact and measure the food, reduce the interference of the external environment, and obtain accurate sensed temperature; in addition, the temperature sensor may be located outside the box 900, so as to avoid compressing the food storage space in the box 900, and at the same time reduce the influence of the low temperature gas delivered by the fresh-keeping device 100 to the inside of the box 900 directly blowing to the temperature sensor on the measurement of the sensed temperature.

[0070] Reference Figure 4 , Figure 4 The structure diagram of the fresh-keeping device of the embodiment of the present invention from another perspective is shown. The humidity sensor 600 is arranged on the side of the dew condensation removal device 200 close to the box 900. The humidity sensor 600 can detect the humidity of the box. When the humidity of the fresh-keeping device 100 is higher, it is easier to generate condensation in the box 900, which means that the condensation risk in the box 900 is higher, which is not conducive to the preservation of food. Therefore, the condensation risk inside the box 900 can be judged by detecting the humidity inside the box 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 conditions. 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, since the internal volume of the fresh-keeping device 100 is relatively large, the temperature measuring component 400 can be provided with multiple groups, 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 with multiple groups, 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 The schematic diagram of the structure of the fresh-keeping device of the embodiment of the present invention from another perspective is shown. The dew 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 inside of the box 900, and the second air outlet is used to connect to the external environment. Therefore, the high-humidity gas in the box 900 can be exchanged with the low-humidity gas in the outside through the fan, wherein 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 less than the connection area of ​​the second air outlet, it is helpful to control the speed of humidity exchange, avoid the rapid exchange of gas causing excessive temperature and humidity change rate to produce condensation, realize the stable regulation of the box humidity, and improve the humidity regulation effect of the dew 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 is toward the outside of the box 900, which can effectively avoid gas backflow, ensure that the gas inside the box 900 can be smoothly discharged to the outside of the box 900, and improve the dew condensation removal efficiency of the dew 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 beneficial to the preservation of food, inhibiting the physiological activity of food, reducing the generation of water vapor, and thus helping to reduce the risk of condensation inside the preservation device 100.

[0074] Therefore, during the operation of the fresh-keeping device 100, the control device 700 can accurately measure the parameters that affect the preservation of food through the switch detection component 500 and the temperature measurement component 400, so as to help determine the state of the fresh-keeping environment inside the box 900, and then accurately control the decondensation 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, and a refrigerated transport vehicle, which is not specifically limited in the present invention.

[0075] The fresh-keeping equipment described in the embodiment of the present invention is intended to more clearly illustrate the technical solution of the embodiment of the present invention, and does not constitute a limitation on the technical solution provided by the embodiment of the present invention. Those skilled in the art can know that with the evolution of fresh-keeping equipment and the emergence of new application scenarios, the technical solution provided by the embodiment of the present invention is also applicable to similar technical problems.

[0076] It can be understood by those skilled in the art that Figures 1 to 5 The structure of the fresh-keeping device shown in the figure does not constitute a limitation on the embodiments of the present invention, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0077] Based on the structure of the above-mentioned fresh-keeping device, various embodiments of the anti-condensation control method of the fresh-keeping device of the present invention are proposed.

[0078] refer to Figure 6 , Figure 6 is a flow chart of an anti-condensation control method for a fresh-keeping device provided by an embodiment of the present invention. The flow chart of the anti-condensation control method for a fresh-keeping device can be applied to Figure 1 , Figure 2 , Figure 3 , Figure 4 or Figure 5 The flowchart of the fresh-keeping device and the anti-condensation control method of the fresh-keeping device shown in the figure includes but is not limited to the following steps:

[0079] Step S100, obtaining the switch state of the box, sensing the temperature and the humidity of the box;

[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 switch state of the cabinet, the sensed temperature and the cabinet humidity.

[0081] It can be understood 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 condensation generation 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 it is 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 when the air is cooled to saturation is lower, and condensation is more likely to occur inside the cabinet, that is, the condensation risk inside the cabinet is higher. Specifically, the condensation risk inside the cabinet can be determined by judging whether the cabinet humidity exceeds a preset humidity threshold. For example, when the cabinet humidity exceeds the preset humidity threshold, it can be considered that the condensation risk inside the cabinet is high, wherein the condensation risk degree inside the cabinet can be determined according to the difference between the cabinet humidity and the preset humidity threshold.

[0083] The sensed temperature obtained by contact measurement of food can accurately reflect the intensity of the physiological activity of the food. 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 physiological activity of the food, 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, it can be considered that the physiological activity of the food is suppressed, reducing the generation of water vapor, 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 impacts 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 different intensities of the food's own physiological activities at different sensing 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 the fan, so that the humidity of the box is reduced, thereby 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 inhibited, 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 determine the condensation risk of the fresh-keeping equipment by obtaining the cabinet switch state, sensing temperature and cabinet temperature, and thereby can more accurately control the working states of the decondensation device, the deoxygenation device and the compressor, thereby accurately lowering the temperature of the food and reducing 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 can be discharged in time through the decondensation device, thereby effectively reducing the condensation risk of the fresh-keeping equipment and helping to improve the fresh-keeping effect of the fresh-keeping equipment on the food.

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

[0088] It is understandable that the food material is a vegetable or a fruit, and the physiological activities of the food material include transpiration and respiration. When the food material is transpiring, the water in the food material will be consumed, resulting in a decrease in the water content of the food material, and the water discharged from the food material to the box will increase the humidity of the box, increasing the risk of condensation in the box. When the food material is respiring, the organic matter in the food material will be consumed, resulting in accelerated corruption of the food material, which is not conducive to the storage of the food material. When the fresh-keeping device is turned on, the gas inside the box will be violently exchanged with the gas outside. If the high-humidity and high-temperature gas from the outside enters the box, it will not only increase the humidity of the box and the ambient temperature inside the box, but also cause the transpiration or respiration of the food material to intensify, produce a large amount of water vapor, and thus increase the risk of condensation. Therefore, the control device can determine the current condensation risk of the box by obtaining the switch state of the box, sensing the temperature and the humidity of the box, which helps to control the operation of the decondensation device, the deoxygenation device and the 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 switch state of the box and the humidity of the box;

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

[0092] It is understandable that when the box is in a closed state, the humidity of the box mainly comes from the water vapor generated by the physiological activities of the food, and the risk of condensation is low. When the box is in an open state, the gas in the box will exchange with the outside gas, which may cause the humidity of the box to change, so it can be considered that the box is prone to condensation risk. The box switch state can determine whether the box is in an open or closed state, and then judge whether the gas in the box is exchanged with the outside gas. When the box humidity is higher, the temperature when the air is cooled to saturation is lower, and the easier it is to produce condensation inside the box, that is, the higher the condensation risk inside the box. Therefore, according to the box switch state and the box humidity, the condensation risk of the box can be effectively judged. When there is a condensation risk in the box, the fresh-keeping equipment can be controlled to switch from the normal refrigeration mode to the anti-condensation mode to reduce the condensation risk of the box. It should be noted that when the box is opened, the high-humidity gas from the outside is exchanged with the low-humidity gas in the box, which may cause the humidity of the box to rise, the sensed temperature to rise, or the oxygen content to rise. At this time, the normal refrigeration mode cannot guarantee the fresh-keeping effect. In the anti-condensation mode, the control device will control the working status of the decondensation device, deoxygenation device and compressor according to different parameters to reduce the risk of condensation in the fresh-keeping equipment. The decondensation device exchanges the high-humidity gas in the box with the low-humidity gas outside to reduce the humidity of the box, thereby reducing the risk of condensation in the box. By adjusting the working status of the compressor to adjust the temperature change rate of both the ambient temperature and the sensed temperature, the food can be quickly cooled. The deoxygenation device 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 down 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 a 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 causing the fresh-keeping equipment to run in the wrong anti-condensation mode.

[0097] Reference Figure 8 , Figure 8 The specific flow chart of controlling the fresh-keeping device to operate in the first anti-condensation mode provided by the embodiment of the present invention includes but is 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 a first anti-condensation mode.

[0099] It is understandable that when the cabinet switch state is on and the cabinet humidity is lower than the preset humidity threshold, it means that after the fresh-keeping device is turned on, the low-temperature gas inside the cabinet is violently exchanged with the high-temperature gas outside, and because the air humidity outside the cabinet is lower than or equal to the air humidity inside the cabinet, the humidity inside the cabinet is lower than the preset humidity threshold, wherein, when the cabinet humidity exceeds the preset humidity threshold, it can be considered that the condensation risk inside the cabinet is high. Although the humidity inside the cabinet is lower than the preset humidity threshold, the process of exchanging the gas inside the cabinet with the outside gas may cause the ambient temperature inside the cabinet to rise, causing the sensed temperature of the food to rise, aggravating the physiological activity of the food, causing the food to release more water vapor, and then causing the cabinet humidity to rise. Therefore, when the cabinet switch state is on and the cabinet humidity is lower than the preset humidity threshold, the fresh-keeping device is controlled to operate in the first anti-condensation mode, and the control device controls the decondensation device, the deoxygenation device and the compressor working state according to the sensed temperature to reduce the ambient temperature of the cabinet, thereby reducing the sensed temperature of the food to inhibit the physiological activity of the food.

[0100] It should be noted that the fresh-keeping equipment operates in the first anti-condensation mode. When the sensed temperature is higher than the preset temperature threshold, the control device controls the compressor to operate at high power to lower the ambient temperature of the box, thereby lowering the sensed temperature of the food so that the sensed temperature is lower than the preset temperature threshold. The higher the temperature of the food, the more active the physiological activity and the shorter the storage time of the food. If the food cannot be cooled down in time, the spoilage of the food may be accelerated. In addition, while the control device controls the compressor to operate at high power, it also controls the decondensation removal device to maintain the current working state to maintain the humidity of the box.

[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 the high-power operation of the compressor means that the compressor operates at a power higher than that before the fresh-keeping device is turned on, so as to improve the cooling effect of the box. For example, when the operating power of the compressor is 500 W before the fresh-keeping device is turned on, the operating power of the compressor when the high-power operation is performed may be 600 W. The specific power parameter may be set according to actual usage, and the present invention does not make any specific limitation.

[0103] It should be noted that when the box switch state is in the on 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 on state to the off 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 Fig. 9 , Fig. 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 a preset humidity threshold, the fresh-keeping device is controlled to operate in a 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 is violently exchanged with the high-humidity gas outside, 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 working states of the decondensation device, the deoxygenation device and the compressor according to the sensed temperature to lower the ambient temperature of the cabinet, thereby lowering the sensed temperature of the food, so as to inhibit the physiological activity of the food, and avoid further increase in humidity in the cabinet due to the physiological activity of the food.

[0108] Reference Fig. 9 , Fig. 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 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.

[0110] It is understandable 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 gas inside the cabinet is violently exchanged with the high-humidity gas outside, 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, and the control device controls the decondensation device, the deoxygenation device and the compressor to operate according to the sensed temperature and cabinet humidity, so as 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 when the humidity of the gas in the box is high, it will not only increase the risk of condensation in the box, but also promote the physiological activities of the food, which will reduce the preservation effect of the preservation equipment. In the second anti-condensation mode, the control device controls the decondensation device to exchange the high-humidity gas in the box with the low-humidity gas outside to reduce the humidity of the box and avoid condensation in the box due to excessive humidity. At the same time, the control device also controls the compressor to run at high power to cool the food so that the sensed temperature is lower than the preset temperature threshold.

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

[0114] It should be noted that when the cabinet switch state is in the on state and the cabinet 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 cabinet 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 respectively controlled according to the sensed temperature and the cabinet humidity, so as to avoid the decondensation device, the deoxygenation device and the compressor of the fresh-keeping equipment from continuously exchanging gas in the cabinet 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 Fig.10 , Fig.10 This is a specific flow chart of controlling the operation of the fresh-keeping device according to the 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 understandable that the control device controls the decondensation device to reduce the humidity of the box, so that the humidity of the box is lower than the preset humidity threshold; the control device controls the compressor to cool the food in the box, so that the sensed temperature of the food is lower than the preset temperature threshold. When the sensed temperature is lower than the preset temperature threshold, the control device controls the deoxygenation device to operate to reduce the oxygen content in the box. It should be noted that the physiological activities of food will be suppressed in a low-temperature and low-oxygen environment, which can effectively increase the storage time of food.

[0120] Reference Fig.11 , Fig.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 operation of the decondensation removal device, the deoxygenation device and the compressor of the fresh-keeping device is controlled 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 run the second anti-condensation mode to reduce the condensation risk of the fresh-keeping device. When the fresh-keeping device runs 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 cabinet humidity to reduce the cabinet humidity, the sensed temperature of the food and the oxygen content in the cabinet. For example, the control device can control the decondensation device to work to reduce the cabinet humidity; control the compressor to change the operating power so that the compressor outputs a lower temperature gas 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 work to reduce the oxygen content in the cabinet.

[0123] Reference Fig.12 , Fig.12 This is a specific flow chart of controlling the operation of the fresh-keeping device according to the sensed temperature and the 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 cabinet humidity 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 Fig.13 , Fig.13 The specific flow chart of controlling the fresh-keeping device to operate in the third anti-condensation mode provided by the embodiment of the present invention includes but is 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 cabinet humidity.

[0128] It is understandable that the control device obtains the switch state of the box, senses the temperature and the humidity of the box, determines the condensation risk of the box according to the switch state of the box and the humidity of the box, and then controls the operation mode of the fresh-keeping device according to the condensation risk to reduce the condensation risk in the box. The fresh-keeping device has a variety of different operation modes. In different operation modes, the control device controls the working states of the decondensation device, the deoxygenation device and the compressor according to different parameters. When the fresh-keeping device operates in the third anti-condensation mode, the control device controls the operation of the decondensation device, the deoxygenation device and the compressor according to the humidity of the box.

[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 inhibit 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 cabinet may rise due to the water vapor generated by the physiological activities of the food. At this time, the risk of condensation in the cabinet is high, but the cabinet 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 cabinet humidity, so that the cabinet humidity is lower than the preset humidity threshold.

[0130] Reference Fig.14 , Fig.14 The specific flow chart of controlling the fresh-keeping device to operate in the third anti-condensation mode provided by the embodiment of the present invention includes but is not limited to the following steps:

[0131] Step S270: When the cabinet switch state is in the closed 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 third anti-condensation mode.

[0132] It is understandable that when the cabinet switch state 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 the third anti-condensation mode. At this time, the control device controls the decondensation device in the cabinet to open, and exchanges the high-humidity gas in the cabinet with the low-humidity gas outside to reduce the cabinet humidity. It should be noted that when the cabinet is closed, the food in the cabinet will produce moisture during physiological activities, causing the cabinet humidity to rise. If the moisture in the cabinet cannot be discharged in time, it may cause the cabinet humidity to 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, thereby 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 cabinet. When the humidity of the cabinet is lower than the preset humidity threshold, the control device will control the dew removal device to turn off.

[0135] refer to Fig.15 , Fig.15 A structural schematic 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, and 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] The memory 1510 is a non-transitory computer-readable storage medium that can be used to store non-transitory software programs and non-transitory computer executable programs, such as the control method of the air conditioner in the above embodiment of the present invention. The processor 1520 implements the anti-condensation method of the fresh-keeping device in the above embodiment of the present invention by running the non-transitory software program and instructions stored in the 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 an application required by 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-transitory memory 1510, such as at least one disk storage device, a flash memory device, or other non-transitory solid-state storage device. It should be noted that the memory 1510 may optionally include a memory 1510 remotely arranged 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, Fig. 9 Method step S250 and method step S251, Fig.10 Steps S300 to S310 of the method, Fig.11 Step S240 of the method, Fig.12 In the method step S320, Fig.13 In step S260 of the method and Fig.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, it is possible to determine whether the temperature fluctuation occurs inside the box through 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, the sensed temperature and the box humidity can be used to comprehensively evaluate the condensation risk of the box, so that the operation of the decondensation device, the deoxygenation device and the 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, and at the same time using the decondensation device 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 aspect 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 900, a decondensation device 200, a deoxygenation device 300, and a switch detection component 500. The fresh-keeping device 100 is provided with a receiving cavity, and the box 900 is arranged in the receiving cavity. A protrusion for moving the box 900 is arranged on the side of the box 900 away from the receiving cavity. The user can pull the box 900 out of the receiving cavity or push the box 900 into the receiving cavity through the protrusion. A temperature measuring component is arranged in the box 900, and the temperature measuring component includes a temperature sensor and a heat conducting component 410 installed at the bottom of the box 900. The temperature sensor is installed on the side of the heat conducting component 410 close to the receiving cavity. When the food is placed in the box 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 receiving cavity, and is used to separate the high-humidity gas in the box 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 in the box 900 to reduce the oxygen content in the box 900. The humidity sensor 600 is arranged on a side of the decondensation removal device 200 close to the box 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 understandable 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 inside of the box 900, and the second air outlet is used to connect to the external environment, so the high-humidity gas in the box 900 can be exchanged with the low-humidity gas outside through the fan, wherein 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 less than the connection area of ​​the second air outlet, it is helpful to control the speed of humidity exchange, avoid the rapid exchange of gas causing excessive temperature and humidity change rate to produce condensation, achieve stable regulation of the box 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 toward the outside of the box 900, which can effectively avoid gas backflow, ensure that the gas inside the box 900 can be smoothly discharged to the outside of the box 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.
