Technical Field

[0001] The present invention relates to the technical field of freshness-keeping control, and in particular to a storage device and a control method and apparatus thereof, and a readable storage medium. Background Art

[0002] Cryogenic storage is a commonly used strategy for preserving food. Cryogenic storage means storing food in a relatively low temperature environment.

[0003] However, the effect of cryopreservation is limited, and the refrigeration equipment needs to work for a long time to maintain the low temperature environment, which is easily damaged. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0005] To this end, a first aspect of the present invention provides a method for controlling a storage device.

[0006] A second aspect of the present invention provides a control device for a storage device.

[0007] A third aspect of the present invention provides another control device for a storage device.

[0008] A fourth aspect of the present invention provides a readable storage medium.

[0009] A fifth aspect of the present invention provides a storage device.

[0010] A sixth aspect of the present invention provides another storage device.

[0011] In view of this, according to a first aspect of the present invention, the present invention provides a control method for a storage device, the storage device comprising a storage cavity, a ventilation valve connected to the storage cavity, a refrigeration device for reducing the temperature in the storage cavity, and a vacuum pump for adjusting the vacuum degree in the storage cavity, the control method comprising: in response to a first input of a preservation program, performing a preservation operation, the preservation operation comprising: controlling the ventilation valve to be open for a first time length; controlling the refrigeration device to operate until the temperature value in the storage cavity is reduced to a first target temperature value; controlling the vacuum pump to operate until the vacuum degree in the storage cavity is reduced to a target vacuum degree; wherein the target vacuum degree and the first target temperature value are related to the preservation program.

[0012] The technical solution of the present application proposes a control method for a storage device. By running the above control method, the rate of increase in the temperature of food in the storage cavity can be slowed down. Therefore, the food in the storage cavity can be kept at a low temperature for a longer time to ensure the preservation effect.

[0013] In addition, the technical solution of the present application can reduce the number of startups and working hours of the refrigeration device, thereby achieving the effect of reducing the power consumption of the storage device.

[0014] The technical solution of the present application is implemented based on the following principles. Specifically, when food is placed in a storage cavity, the food has two channels to transfer heat with the environment, namely, contact heat transfer and air convection. By running the control method proposed in the present application, after the temperature in the storage cavity is lowered to a first target temperature value by a refrigeration device, a vacuum pump is used to extract the gas in the storage cavity. After the vacuum pump extracts the gas in the storage cavity, the amount of gas in the storage cavity is reduced, so that the heat transfer mode in the storage cavity is reduced from contact heat transfer and air convection to contact heat transfer.

[0015] During this process, the rate at which low-temperature food absorbs heat is reduced, so the food in the storage cavity can maintain a low temperature for a longer time to ensure the preservation effect.

[0016] It is worth pointing out that after the gas in the storage cavity is extracted by a vacuum pump, a vacuum will be formed in the storage cavity. For microorganisms and bacteria, their reproduction rate in a vacuum environment will be reduced. Therefore, the technical solution of the present application can not only extend the preservation time, but also improve the preservation effect.

[0017] In one of the technical solutions, the preservation program can be set to multiple according to the design requirements of the storage device, and different preservation programs correspond to different target vacuum degrees and first target temperature values, so as to achieve targeted preservation of different foods.

[0018] In the above technical solution, the ventilation valve is controlled to be open for a first time so that the gas outside the storage cavity can enter the storage cavity, so that the heat transfer mode of the food in the storage cavity is maintained at contact heat transfer and air convection, thereby ensuring that the refrigeration device has a better refrigeration effect when the refrigeration device is working.

[0019] In one of the technical solutions, the first duration can be set according to the flow rate of the ventilation valve and the volume of the storage cavity, or a fixed value can be selected. For example, the first duration is selected as 5 seconds, and its specific value is not limited here.

[0020] In one of the technical solutions, vacuum refers to the rarefaction of the gas in a vacuum state. If the pressure in the measured device is lower than the atmospheric pressure, a vacuum gauge is required for pressure measurement. The value read from the vacuum gauge is called vacuum. The vacuum value indicates that the actual value of the system pressure is lower than the atmospheric pressure, that is, vacuum = atmospheric pressure - absolute pressure, absolute pressure = atmospheric pressure + gauge pressure (- vacuum).

[0021] In addition, the control method of the storage device proposed in this application also has the following additional technical features.

[0022] In the above technical solution, the vacuum pump is controlled to operate until the vacuum degree in the storage chamber is reduced to a target vacuum degree, specifically including: determining the target operating time of the vacuum pump when the vacuum degree in the storage chamber is reduced to the target vacuum degree; controlling the vacuum pump to operate; obtaining the cumulative operating time of the vacuum pump; and controlling the vacuum pump to stop operating when the cumulative operating time is greater than or equal to the target operating time.

[0023] In this technical solution, the target operating time is determined so as to control the vacuum degree in the storage chamber to be reduced to the target vacuum degree. During this process, there is no need to frequently measure the vacuum degree in the storage chamber, and at the same time, the control difficulty of the storage device is reduced.

[0024] In one of the technical solutions, a correspondence between the target operating time and the target vacuum degree is pre-constructed, so that when the target vacuum degree is determined, the target operating time is determined according to the above correspondence.

[0025] In one of the technical solutions, the above correspondence relationship can be pre-set before the storage device leaves the factory, or it can be measured by running a calibration program after the user purchases the storage device. It can be determined according to actual usage needs and will not be elaborated here.

[0026] In one of the technical solutions, the above-mentioned cumulative timing can be understood as the accumulation of the operating time of the vacuum pump when the storage device is used this time.

[0027] In one of the technical solutions, when the vacuum pump is in continuous operation, the accumulated operation time of the vacuum pump can be understood as the continuous operation time of the vacuum pump.

[0028] In one of the technical solutions, when the vacuum pump is in non-continuous operation, that is, intermittent operation, the cumulative operation time of the vacuum pump can be understood as the cumulative sum of the operation time of multiple starts of the vacuum pump.

[0029] In any of the above technical solutions, after controlling the vacuum pump to stop running, the control method also includes: obtaining the temperature value in the storage cavity; when the temperature value in the storage cavity rises to a second target temperature value, repeating the preservation operation; wherein the second target temperature value is higher than the first target temperature value.

[0030] In this technical solution, when the temperature value in the storage cavity rises to the second target temperature value, it is considered that the temperature of the food in the storage cavity is too high and the fresh-keeping environment in the storage cavity has been destroyed, and the refrigeration device needs to be re-controlled to start in order to lower the temperature in the storage cavity.

[0031] By repeatedly performing the fresh-keeping operation, the storage device can reconstruct the environment for food preservation, thereby ensuring the fresh-keeping effect of the food.

[0032] In one of the technical solutions, the second target temperature value is related to the preservation program, which corresponds to the first target temperature value. Its specific value can be set according to the actual usage scenario of the storage device, which will not be repeated here.

[0033] In one of the technical solutions, the temperature value in the storage cavity can be obtained periodically, such as once every 30 seconds, 1 minute, or 5 minutes, wherein the above time intervals can be determined according to actual usage needs and will not be elaborated here.

[0034] In any of the above technical solutions, the storage device further includes a heat dissipation fan, and the control method further includes: controlling the heat dissipation fan to start and shut down synchronously with the refrigeration device.

[0035] In this technical solution, a heat dissipation fan is provided to dissipate heat from the refrigeration device, thereby reducing the possibility of damage to the refrigeration device due to its own high temperature during the process of cooling the storage cavity, thereby improving the reliability of the storage device operation.

[0036] In the above technical solution, the heat dissipation fan is limited to start and shut down synchronously with the refrigeration device, so that when heat is generated in the refrigeration device, the heat dissipation fan can be used to dissipate heat, and when the refrigeration device is not running, it is controlled to stop running, so as to reduce the power consumption of the storage device.

[0037] In any of the above technical solutions, the control method also includes: obtaining the vacuum degree in the storage cavity; when the vacuum degree decreases from the target vacuum degree, controlling the vacuum pump to operate until the vacuum degree reaches the target vacuum degree.

[0038] In this technical solution, the start and stop of the vacuum pump can be controlled according to the vacuum degree in the storage cavity. In this process, the problem of poor preservation effect caused by poor sealing effect of the storage cavity can be reduced, and at the same time, the preservation effect can be ensured to the greatest extent.

[0039] According to a second aspect of the present invention, the present invention provides a control device for a storage device, the storage device comprising a storage cavity, a ventilation valve connected to the storage cavity, a refrigeration device for reducing the temperature in the storage cavity, and a vacuum pump for adjusting the vacuum degree in the storage cavity, the control device comprising: a response unit for performing a preservation operation in response to a first input of a preservation program, the preservation operation comprising: controlling the ventilation valve to be open for a first time duration; controlling the refrigeration device to operate until the temperature value in the storage cavity is reduced to a first target temperature value; controlling the vacuum pump to operate until the vacuum degree in the storage cavity is reduced to a target vacuum degree; wherein the target vacuum degree and the first target temperature value are related to the preservation program.

[0040] The technical solution of the present application proposes a control device for a storage device, which can slow down the rate of increase in the temperature of food in a storage cavity.

DETAILED DESCRIPTION

[0094] In order to more clearly understand the above aspects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0095] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0096] In one embodiment of the present application, Figure 1 As shown, a control method for a storage device is provided, the storage device includes a storage cavity, a vent valve connected to the storage cavity, a refrigeration device for reducing the temperature in the storage cavity, and a vacuum pump for adjusting the vacuum degree in the storage cavity, and the control method includes:

[0097] Step 102, in response to the first input of the preservation program, executing the preservation operation;

[0098] Among them, the preservation operation includes:

[0099] Step 104, controlling the ventilation valve to be open for a first time period;

[0100] Step 106, controlling the refrigeration device to operate until the temperature value in the storage cavity drops to a first target temperature value;

[0101] Step 108, controlling the vacuum pump to operate until the vacuum degree in the storage chamber is reduced to a target vacuum degree.

[0102] Among them, the target vacuum degree and the first target temperature value are related to the preservation program.

[0103] An embodiment of the present application proposes a control method for a storage device. By running the above control method, the rate of increase in the temperature of food in the storage cavity can be slowed down. Therefore, the food in the storage cavity can be kept at a low temperature for a longer time to ensure the preservation effect.

[0104] In addition, the embodiments of the present application can reduce the number of startups and working hours of the refrigeration device, thereby achieving the effect of reducing the power consumption of the storage device.

[0105] The embodiments of the present application are implemented based on the following principles. Specifically, when food is placed in a storage cavity, the food has two channels to transfer heat with the environment, namely, contact heat transfer and air convection. By running the control method proposed in the present application, after the temperature in the storage cavity is lowered to a first target temperature value by a refrigeration device, a vacuum pump is used to extract the gas in the storage cavity. After the vacuum pump extracts the gas in the storage cavity, the amount of gas in the storage cavity is reduced, so that the heat transfer mode in the storage cavity is reduced from contact heat transfer and air convection to contact heat transfer.

[0106] During this process, the rate at which low-temperature food absorbs heat is reduced, so the food in the storage cavity can maintain a low temperature for a longer time to ensure the preservation effect.

[0107] It is worth pointing out that after the gas in the storage cavity is extracted by a vacuum pump, a vacuum will be formed in the storage cavity. For microorganisms and bacteria, their reproduction rate in a vacuum environment will be reduced. Therefore, the embodiment of the present application can not only extend the preservation time, but also improve the preservation effect.

[0108] In one embodiment, the preservation program can be set to multiple according to the design requirements of the storage device, and different preservation programs correspond to different target vacuum degrees and first target temperature values, so as to achieve targeted preservation of different foods.

[0109] In the above embodiment, the ventilation valve is controlled to be open for a first time so that gas outside the storage cavity can enter the storage cavity, so that the heat transfer mode of food in the storage cavity is maintained at contact heat transfer and air convection, thereby ensuring that the refrigeration device has a better refrigeration effect when the refrigeration device is working.

[0110] In one embodiment, the first duration can be set according to the flow rate of the ventilation valve and the volume of the storage cavity, or a fixed value can be selected. For example, the first duration is selected as 5 seconds, and its specific value is not limited here.

[0111] In one embodiment, vacuum refers to the rarefaction of gas in a vacuum state. If the pressure in the measured device is lower than the atmospheric pressure, a vacuum gauge is required for pressure measurement. The value read from the vacuum gauge is called vacuum. The vacuum value indicates that the actual value of the system pressure is lower than the atmospheric pressure, that is, vacuum = atmospheric pressure - absolute pressure, absolute pressure = atmospheric pressure + gauge pressure (- vacuum).

[0112] In the above embodiment, the vacuum pump is controlled to operate until the vacuum degree in the storage chamber is reduced to a target vacuum degree, specifically including: determining the target operating time of the vacuum pump when the vacuum degree in the storage chamber is reduced to the target vacuum degree; controlling the vacuum pump to operate; obtaining the cumulative operating time of the vacuum pump; and controlling the vacuum pump to stop operating when the cumulative operating time is greater than or equal to the target operating time.

[0113] In this embodiment, the target operating time is determined so as to control the vacuum degree in the storage chamber to be reduced to the target vacuum degree. During this process, there is no need to frequently measure the vacuum degree in the storage chamber, and at the same time, the control difficulty of the storage device is reduced.

[0114] In one of the embodiments, a correspondence between the target operating time and the target vacuum degree is pre-constructed, so that when the target vacuum degree is determined, the target operating time is determined according to the correspondence.

[0115] In one embodiment, the above correspondence relationship can be pre-set before the storage device leaves the factory, or can be measured by running a calibration program after the user purchases the storage device. It can be determined according to actual usage needs and will not be elaborated here.

[0116] In one embodiment, the above-mentioned cumulative timing can be understood as the cumulative running time of the vacuum pump when the storage device is used this time.

[0117] In one embodiment, when the vacuum pump is in continuous operation, the accumulated operation time of the vacuum pump can be understood as the continuous operation time of the vacuum pump.

[0118] In one embodiment, when the vacuum pump is in non-continuous operation, that is, intermittent operation, the cumulative operation time of the vacuum pump can be understood as the cumulative sum of the operation time of multiple starts of the vacuum pump.

[0119] In any of the above embodiments, after controlling the vacuum pump to stop running, the control method also includes: obtaining the temperature value in the storage cavity; when the temperature value in the storage cavity rises to a second target temperature value, repeating the preservation operation; wherein the second target temperature value is higher than the first target temperature value.

[0120] In this embodiment, when the temperature value in the storage cavity rises to the second target temperature value, it is considered that the temperature of the food in the storage cavity is too high and the fresh-keeping environment in the storage cavity has been destroyed, and the refrigeration device needs to be re-controlled to start in order to lower the temperature in the storage cavity.

[0121] By repeatedly performing the fresh-keeping operation, the storage device can reconstruct the environment for food preservation, thereby ensuring the fresh-keeping effect of the food.

[0122] In one of the embodiments, the second target temperature value is related to the preservation program, which corresponds to the first target temperature value. The specific value can be set according to the actual usage scenario of the storage device, which will not be described in detail here.

[0123] In one embodiment, the temperature value in the storage cavity can be obtained periodically, such as once every 30 seconds, 1 minute, or 5 minutes, wherein the above time intervals can be determined according to actual usage needs and will not be elaborated here.

[0124] In any of the above embodiments, the storage device further includes a heat dissipation fan, and the control method further includes: controlling the heat dissipation fan to start and shut down synchronously with the refrigeration device.

[0125] In this embodiment, a heat dissipation fan is provided to dissipate heat from the refrigeration device, thereby reducing the possibility of damage to the refrigeration device due to its own high temperature during the process of cooling the storage cavity, thereby improving the reliability of the storage device operation.

[0126] In the above embodiment, the heat dissipation fan is limited to start and shut down synchronously with the refrigeration device, so that when heat is generated in the refrigeration device, the heat dissipation fan is used to dissipate heat, and when the refrigeration device is not running, it is controlled to stop running, so as to reduce the power consumption of the storage device.

[0127] In any of the above embodiments, the control method further includes: obtaining the vacuum degree in the storage cavity; when the vacuum degree decreases from the target vacuum degree, controlling the vacuum pump to operate until the vacuum degree reaches the target vacuum degree.

[0128] In this embodiment, the start and stop of the vacuum pump can be controlled according to the vacuum degree in the storage cavity. In this process, the problem of poor preservation effect caused by poor sealing effect of the storage cavity can be reduced, and at the same time, the preservation effect can be ensured to the greatest extent.

[0129] In one embodiment, if Figure 2 As shown, the control method of the storage device includes:

[0139] In one embodiment, if Figure 3 As shown, the present invention provides a control device 300 for a storage device, the storage device includes a storage cavity, a ventilation valve connected to the storage cavity, a refrigeration device for reducing the temperature in the storage cavity, and a vacuum pump for adjusting the vacuum degree in the storage cavity, the control device includes: a response unit 302, for responding to a first input of a preservation program and performing a preservation operation, the preservation operation including: controlling the ventilation valve to be open for a first time; controlling the refrigeration device to operate until the temperature value in the storage cavity is reduced to a first target temperature value; controlling the vacuum pump to operate until the vacuum degree in the storage cavity is reduced to a target vacuum degree; wherein the target vacuum degree and the first target temperature value are related to the preservation program.

[0140] The embodiment of the present application proposes a control device 300 for a storage device, which can slow down the rate of increase in the temperature of food in a storage cavity. Therefore, the food in the storage cavity can be kept at a low temperature for a longer period of time to ensure a fresh-keeping effect.

[0141] In addition, the embodiments of the present application can reduce the number of startups and working hours of the refrigeration device, thereby achieving the effect of reducing the power consumption of the storage device.

[0142] The embodiments of the present application are implemented based on the following principles. Specifically, when food is placed in a storage cavity, the food has two channels to transfer heat with the environment, namely, contact heat transfer and air convection. By running the control method proposed in the present application, after the temperature in the storage cavity is lowered to a first target temperature value by a refrigeration device, a vacuum pump is used to extract the gas in the storage cavity. After the vacuum pump extracts the gas in the storage cavity, the amount of gas in the storage cavity is reduced, so that the heat transfer mode in the storage cavity is reduced from contact heat transfer and air convection to contact heat transfer.

[0143] During this process, the rate at which low-temperature food absorbs heat is reduced, so the food in the storage cavity can maintain a low temperature for a longer time to ensure the preservation effect.

[0144] It is worth pointing out that after the gas in the storage cavity is extracted by a vacuum pump, a vacuum will be formed in the storage cavity. For microorganisms and bacteria, their reproduction rate in a vacuum environment will be reduced. Therefore, the embodiment of the present application can not only extend the preservation time, but also improve the preservation effect.

[0145] In one embodiment, the preservation program can be set to multiple according to the design requirements of the storage device, and different preservation programs correspond to different target vacuum degrees and first target temperature values, so as to achieve targeted preservation of different foods.

[0146] In the above embodiment, the ventilation valve is controlled to be open for a first time so that gas outside the storage cavity can enter the storage cavity, so that the heat transfer mode of food in the storage cavity is maintained at contact heat transfer and air convection, thereby ensuring that the refrigeration device has a better refrigeration effect when the refrigeration device is working.

[0147] In one embodiment, the first duration can be set according to the flow rate of the ventilation valve and the volume of the storage cavity, or a fixed value can be selected. For example, the first duration is selected as 5 seconds, and its specific value is not limited here.

[0148] In one embodiment, vacuum refers to the rarefaction of gas in a vacuum state. If the pressure in the measured device is lower than the atmospheric pressure, a vacuum gauge is required for pressure measurement. The value read from the vacuum gauge is called vacuum. The vacuum value indicates that the actual value of the system pressure is lower than the atmospheric pressure, that is, vacuum = atmospheric pressure - absolute pressure, absolute pressure = atmospheric pressure + gauge pressure (- vacuum).

[0149] In the above embodiment, the response unit 302 is specifically used to: determine the target operating time of the vacuum pump when the vacuum degree in the storage chamber is reduced to the target vacuum degree; control the operation of the vacuum pump; obtain the cumulative operating time of the vacuum pump; and control the vacuum pump to stop running when the cumulative time is greater than or equal to the target operating time.

[0150] In this embodiment, the target operating time is determined so as to control the vacuum degree in the storage chamber to be reduced to the target vacuum degree. During this process, there is no need to frequently measure the vacuum degree in the storage chamber, and at the same time, the control difficulty of the storage device is reduced.

[0151] In one of the embodiments, a correspondence between the target operating time and the target vacuum degree is pre-constructed, so that when the target vacuum degree is determined, the target operating time is determined according to the correspondence.

[0152] In one embodiment, the above correspondence relationship can be pre-set before the storage device leaves the factory, or can be measured by running a calibration program after the user purchases the storage device. It can be determined according to actual usage needs and will not be elaborated here.

[0153] In one embodiment, the above-mentioned cumulative timing can be understood as the cumulative running time of the vacuum pump when the storage device is used this time.

[0154] In one embodiment, when the vacuum pump is in continuous operation, the accumulated operation time of the vacuum pump can be understood as the continuous operation time of the vacuum pump.

[0155] In one embodiment, when the vacuum pump is in non-continuous operation, that is, intermittent operation, the cumulative operation time of the vacuum pump can be understood as the cumulative sum of the operation time of multiple starts of the vacuum pump.

[0156] In any of the above embodiments, after controlling the vacuum pump to stop running, the response unit 302 is also used to: obtain the temperature value in the storage cavity; when the temperature value in the storage cavity rises to a second target temperature value, repeat the preservation operation; wherein the second target temperature value is higher than the first target temperature value.

[0157] In this embodiment, when the temperature value in the storage cavity rises to the second target temperature value, it is considered that the temperature of the food in the storage cavity is too high and the fresh-keeping environment in the storage cavity has been destroyed, and the refrigeration device needs to be re-controlled to start in order to lower the temperature in the storage cavity.

[0158] By repeatedly performing the fresh-keeping operation, the storage device can reconstruct the environment for food preservation, thereby ensuring the fresh-keeping effect of the food.

[0159] In one of the embodiments, the second target temperature value is related to the preservation program, which corresponds to the first target temperature value. The specific value can be set according to the actual usage scenario of the storage device, which will not be described in detail here.

[0160] In one embodiment, the temperature value in the storage cavity can be obtained periodically, such as once every 30 seconds, 1 minute, or 5 minutes, wherein the above time intervals can be determined according to actual usage needs and will not be elaborated here.

[0161] In any of the above embodiments, the storage device further includes a heat dissipation fan, and the response unit is further used to control the heat dissipation fan to start and shut down synchronously with the refrigeration device.

[0162] In this embodiment, a heat dissipation fan is provided to dissipate heat from the refrigeration device, thereby reducing the possibility of damage to the refrigeration device due to its own high temperature during the process of cooling the storage cavity, thereby improving the reliability of the storage device operation.

[0163] In the above embodiment, the heat dissipation fan is limited to start and shut down synchronously with the refrigeration device, so that when heat is generated in the refrigeration device, the heat dissipation fan is used to dissipate heat, and when the refrigeration device is not running, it is controlled to stop running, so as to reduce the power consumption of the storage device.

[0164] In any of the above embodiments, the response unit 302 is further used to: obtain the vacuum degree in the storage cavity; and when the vacuum degree decreases from the target vacuum degree, control the vacuum pump to operate until the vacuum degree reaches the target vacuum degree.

[0165] In this embodiment, the start and stop of the vacuum pump can be controlled according to the vacuum degree in the storage cavity. In this process, the problem of poor preservation effect caused by poor sealing effect of the storage cavity can be reduced, and at the same time, the preservation effect can be ensured to the greatest extent.
