A first storage chamber 102; wherein the temperature of the third airflow is lower than the temperature of the first airflow before the third airflow is introduced into the first storage room, and / or the absolute humidity of the third airflow is low The absolute humidity of the first airflow.

The food storage device may be various devices capable of storing food. The food storage equipment may be a refrigerator or the like.

The food stored by the food storage device may include: various solid foods, and may also include liquid fluids; in some embodiments, a solid and liquid mixed diet.

In short, the food storage device can be used for storing various foods.

In some embodiments, the second storage compartment 101 may be used for foods requiring low temperature storage; the first storage compartment 102 may be used for foods that do not require low temperature but need to be stored dry; for example, bread stored at low temperature, and the like.

The second storage chamber 101 and the first storage chamber 102 may be storage chambers for food storage.

In this embodiment, the second storage chamber 101 and the first storage chamber 102 are relatively independent, and can be divided by a cavity wall.

In some embodiments, the first diversion device 103 is at least partially located on the cavity wall. The first diversion device 103 includes at least a first diversion channel, and one end of the first diversion channel is in communication with the second storage chamber. 101. The other end communicates with the first storage chamber 102. The first diversion device 103 may include at least a conduction component that connects the second storage chamber 101 and the first storage chamber 102.

In other embodiments, the first diversion device 103 is provided with a driving component for driving the third airflow into the first storage chamber 102 in addition to the diversion component. The driving assembly provides a driving force for the first gas in the second storage chamber 101 to flow into the first storage chamber 102.

In this embodiment, the state of the first diversion device 103 may include: a diversion state and a non-diversion state; and when the first diversion device 103 is in the diversion state, the first diversion device 103 A diversion channel is in a conducting state, and the first diversion device 103 can introduce the airflow in the second storage chamber 101 into the first storage chamber 102. When the first diversion device 103 is in a non-diversion state, a first diversion channel of the first diversion device 103 is in a truncated state, and the first diversion channel is truncated and located in the second storage chamber 101. The first gas cannot be introduced into the first storage chamber 102.

In other embodiments, if the first diversion device 103 includes a driving component, when the first diversion device 103 is in the diversion state, the driving component is in a working state. When the first diversion device 103 is in a non-diversion state, the driving assembly is in a non-working state. If the driving component is in a non-working state, the driving device does not work, and the driving component does not provide a driving force for the third airflow to be introduced into the first storage chamber 102. If the driving assembly is in an operating state, the driving device operates, and the driving assembly provides a driving force for the third airflow to be introduced into the first storage chamber 102.

The refrigeration system may include: various types of refrigeration capable devices, which may be divided into a cold end with a lower temperature and a hot end with a higher temperature. In this embodiment, a cold end of a refrigeration system is provided in the second storage room 101. In this way, the temperature in the second storage room 101 can be reduced, for example, to a preset temperature. For example, lowering the temperature values within the freezing temperature range, such as 5 degrees Celsius, 0 degrees Celsius, 0 degrees Celsius, -5 degrees Celsius, -10 degrees Celsius, -15 degrees Celsius.

For example, refrigerators and compressors. In some embodiments, the refrigeration system may include four basic components: a refrigeration compressor, a condenser, a throttle valve and an evaporator. Refrigeration compressors, condensers, throttles and evaporators are connected by pipes in order to form a closed system. The refrigerant continuously circulates in the system, changes state, and exchanges heat with the outside world. The refrigerator compresses the steam with lower pressure into steam with higher pressure, which reduces the volume of the steam and increases the pressure. The compressor sucks the lower-pressure working medium vapor from the evaporator, increases the pressure, and sends it to the condenser, where it condenses into a higher-pressure liquid, which is throttled by the throttle valve, and becomes more pressure-sensitive. After the low liquid, it is sent to the evaporator, which absorbs heat and evaporates in the evaporator to become a steam with lower pressure, and then sends it to the inlet of the compressor to complete the refrigeration cycle.

In this way, cooling in the second storage chamber 101 can be achieved, so that the gas in the second storage chamber 101 can be reduced to a specific temperature. In some embodiments, the second storage chamber 101 may be a freezing chamber, and may be used to freeze food.

In this embodiment, the first storage chamber 102 may be another storage chamber that is in communication with the second storage chamber 101 through a first diversion device 103. If the second storage compartment 101 is a freezing compartment, the first storage compartment 102 may be a dry refrigerating compartment. In this embodiment, the temperature of the airflow in the drying and refrigerating chamber may be higher than the gas in the second storage chamber 101. The absolute humidity of the third airflow is lower than the absolute humidity of the first airflow.

The absolute humidity may be: the mass of water vapor contained in each cubic meter of wet air, that is, the density of water vapor, and the unit is g / m ³ .

The relative humidity refers to the percentage of the water vapor pressure in the air flow and the saturated water vapor pressure at the same temperature. Or the ratio of the absolute humidity of the airflow to the maximum absolute humidity that can be reached at the same temperature.

At this time, the absolute humidity of the first airflow in the first storage chamber 102 is relative to the absolute humidity of the third airflow in the second storage chamber 101. Here, in order to reduce the humidity of the airflow in the first storage chamber 102, the third airflow in the second storage chamber 101 is introduced into the first storage chamber 102, and after the third airflow is introduced into the first storage chamber 102, the first The first airflow in the first storage chamber 102 is mixed. Through diffusion, the average value of the absolute humidity of the mixed airflow in the first storage chamber 102 is reduced, so that the first storage chamber 102 is dried; A storage room 102 is suitable for storing foods with relatively low temperature and low humidity.

In this embodiment, the first diversion device 103 is provided to connect the second storage chamber 101 and the first storage chamber 102, and the third airflow having a low absolute humidity in the second storage chamber 101 flows into the first storage chamber 102.

Step S120: Determine whether the execution conditions of the drying program are satisfied according to the execution status;

Step S130: If the execution status meets the execution conditions of the drying program, execute the drying program.

The method for controlling a food storage device provided in this embodiment may be applied to a food storage device as shown in FIG. 1 to FIG. 2.

Of course, the above is only an example of a preset program, and the specific implementation is not limited to any one of the above programs.

For example, the defrosting process will increase the humidity in the food storage device. In this way, when to start the drying process to ensure that the drying process is started when necessary and closed when it is not necessary, on the one hand, it is necessary to reduce the unnecessary opening of the drying process. The waste of power caused by the implementation can also reduce the phenomenon that the first storage room cannot meet the drying requirements in the food storage conditions caused by the failure to turn on when necessary.

As another example, in this embodiment, a second airflow with a low temperature and a low absolute humidity in the second storage chamber is introduced into the first storage chamber for drying; if the cooling process has not been started or the cooling time is not long enough, obviously even if the drying process is started, The drying effect is also not good. Therefore, in this embodiment, the timing of starting the drying program can be determined according to the execution status of the refrigeration program, thereby ensuring the drying effect.

In some embodiments, the step S110 may include: obtaining an execution status of a defrost program;

The step S120 may include at least one of the following:

If the execution status indicates the end of the defrost program execution, determining that the execution status meets the execution conditions of the drying program;

If the execution state indicates that the time difference between the current time and the start time of the defrost program is greater than a preset time difference, determining that the execution state meets the execution conditions of the drying program;

If the execution state indicates that the defrost program is being executed, detecting a sensing parameter, and determining whether the execution condition of the drying program is satisfied according to the sensing parameter.

The execution status of the defrost program here may include: the execution status, the non-execution status, and the execution end status.

If the execution of the defrosting program ends, the humidity in the first storage room may increase because of the defrosting, so the execution conditions of the drying program may be met.

If the defrost program has not yet been performed, in order to reduce the absolute humidity, during the defrost program, the humidity in the first storage room exceeds the upper limit of the humidity of the food storage conditions as much as possible, first perform a drying program for a period of time, so To reduce the humidity in the first storage chamber before the defrost program starts.

If the defrost program is currently being executed, and if the defrost program causes the humidity in the first storage room to increase excessively, the execution of the defrost program may be controlled according to the sensing parameters, and the execution of the drying program may be further controlled by the execution of the defrost program.

The first humidity threshold may be a relative humidity threshold, and the range of the relative humidity threshold may be various, for example, 40%, 50%, 45%, 30%, or 35%.

If the humidity in the first storage chamber is not less than the first humidity threshold, it is determined that the execution condition of the drying program is satisfied.

In some embodiments, if it is determined that the execution condition is satisfied, the method further includes: determining a drying parameter. The drying parameter may include an opening parameter and a time parameter. The time parameters may include: open time parameters, end time parameters, time parameters for opening parameter switching performed by the drying program, etc .; here, it is only an example, and the specific implementation is not limited thereto.

In some embodiments, if the humidity parameter indicates that the humidity in the first storage room is not less than the first humidity threshold, determining that the execution condition of the drying program is satisfied includes:

Determining a first time interval between the current time and the execution time of the last defrost program;

If the time interval is greater than the first time interval, it is determined that the execution conditions of the drying program are satisfied after the defrost program is executed.

For example, the first time interval may be a preset time interval, which may be determined according to the drying capacity of the first storage chamber by the drying program, or may be written in the food storage device in advance. The first time interval may be a value of 10 minutes, 8 minutes, or 5 minutes.

In some embodiments, the method further includes:

If the time interval is not greater than the first time interval, it is determined that the execution condition of the drying program is not currently met, and the preset duration of the defrost program is postponed to determine that the execution condition of the drying program is not currently met.

In this embodiment, if the execution time from the previous defrost program is relatively short, the current defrost program may be unnecessary, so the defrost program is postponed. In addition, it is determined at the same time that the execution conditions of the drying program are not currently satisfied, and it is not necessary to execute the drying program.

In some embodiments, the method further includes:

The first refrigeration parameter and the second refrigeration parameter are different and determine the current refrigeration capacity of the refrigeration system. In some embodiments, the refrigeration capacity corresponding to the first refrigeration parameter is higher than the refrigeration capacity corresponding to the second refrigeration parameter.

Both the first refrigeration parameter and the second refrigeration parameter may be referred to as a refrigeration parameter, and may include at least one of the following:

Cooling power, the greater the cooling work, the stronger the cooling capacity, and the faster and better the cooling effect;

Gears of a refrigeration compressor; for example, the higher the gear, the stronger the cooling capacity and the faster and better the cooling effect.

In some embodiments, the step S110 may include:

Get the execution status of the cooling program;

The step S120 may include at least one of the following:

If it is determined that the execution condition of the drying program is satisfied according to the elapsed time of the cooling program reaching the first time threshold;

If the execution time of the refrigeration program after the defrost program is completed reaches a second time threshold, it is determined that the execution conditions of the drying program are satisfied.

In some embodiments, if the cooling program has been executed for a period of time, indicating that the absolute humidity of the second airflow in the second storage room has decreased by a specific value, it can be used for the second storage room with a higher drying temperature. When the elapsed time of the cooling program reaches the first time threshold, it is determined that the execution conditions of the drying program are satisfied to start the execution of the drying program.

For example, after the food storage device is started, the food storage device automatically starts a cooling program. If the cooling program in the food storage device has reached the first time threshold at this time, it is determined that the execution conditions of the drying program are met.

For another example, after new food is put in the first storage room of the food storage device, or after the first storage room is opened, the time when the new food is put in or opened is taken as the execution of the cooling program. The timing start time of the time, after the timing reaches the first time threshold, it is determined that the execution condition of the drying program is satisfied, and the execution of the drying program is started in time.

In some embodiments, since the defrost program may cause the humidity in the first storage room to increase, in this implementation, if the execution time of the cooling program after the defrost program is completed reaches a second time threshold, it is determined The execution conditions of the drying program are satisfied. After the execution time of the refrigeration program reaches the second time threshold, the execution of the drying program is restarted to ensure the drying effect of the drying program.

In some embodiments, the first time threshold and the second time threshold may be equal to or different from each other.

The first time threshold and the second time threshold may be preset values, or may be determined according to a defrost condition or a refrigeration parameter of a refrigeration program. If the current cooling power is low, the first time threshold or the second time threshold may be relatively long. For example, the first time threshold and the second time threshold may be set to 10 minutes, 15 minutes, 20 minutes, or 5 minutes.

In some embodiments, the first time threshold and the second time threshold may be set with different backup selection values, and may be based on a cooling parameter of the current cooling program and / or a temperature and / or humidity of the first storage room. , Selecting a first time threshold and / or a second time threshold suitable for judging a current drying program execution condition from the backup selection values.

Determining, according to the temperature parameter and / or the humidity parameter, an opening parameter of an airflow channel that introduces a second airflow in a second storage room into the first storage room to be mixed with the first airflow in the first storage room; The absolute humidity of the second airflow is lower than the absolute humidity of the first airflow; and / or the temperature of the second airflow is lower than the temperature of the first airflow.

In some embodiments, the step S140 further includes:

Determining a heating parameter of the heating component in the second storage room according to the temperature parameter and / or the humidity parameter.

In some embodiments, the method further comprises: starting the drying program according to a control mode.

For example, according to whether there is humidity sensing, it can be divided into humidity sensing mode and humidity non-sensing mode. Therefore, starting the corresponding drying program according to the control mode includes at least one of the following: jointly controlling the execution of the drying program based on the humidity parameter and temperature parameter based on the humidity sensing mode; The sensed temperature parameter controls the execution of the drying program.

In other embodiments, the initiating a corresponding drying program according to the control mode includes at least one of the following: according to a joint control mode, jointly controlling the drying program according to an association relationship between the drying program and the preset program.

In the joint control mode, the execution parameters of the drying program and the preset program are determined together. In this way, the drying program is equivalent to affecting the execution parameters or execution conditions of the preset program. For example, according to the humidity parameter and / or temperature parameter in the first storage room, the execution parameters of the defrosting program, the cooling program, and the drying program are collectively controlled.

In the independent control mode, the control of the drying program and other programs (that is, the preset program) is relatively independent, that is, the execution of the drying program does not cause the execution parameters of the defrost program or the refrigeration program.

In some embodiments, the first diversion device may be periodically controlled to enter a diversion state, so that the third airflow in the third storage chamber is introduced into the first storage chamber. In still other embodiments, the first diversion device may be controlled to enter a diversion state according to the humidity and / or humidity in the first storage chamber, so that the low-temperature and low-humidity gas in the first storage chamber is introduced into the first Storage room.

In some embodiments, the first diversion device is controlled to enter a diversion state within a predetermined period of time. For example, the first diversion device is controlled to enter a diversion state within a predetermined period of time after the food storage device is activated. As another example, after the defrosting process is performed on the food storage device, the humidity of the airflow in the food storage device is increased by the defrosting process, and a drying process is required; therefore, in some embodiments, after the defrosting is finished, the control is performed. The first diversion device enters a diversion state.

An embodiment of the present application provides a computer storage medium, where the computer storage medium stores computer-executable instructions; after the computer-executable instructions are executed, control of a food storage device provided by one or more of the foregoing technical solutions can be implemented method.

The computer storage media provided in the embodiments of the present application may be various types of storage media, for example, non-transitory storage media.

Provide several specific examples according to any of the above technical solutions:

Example 1:

As shown in FIG. 5 and FIG. 6, the technical solution of the drying storage device of the present application is shown in the figure (side cross-section). The main body is a freezer compartment 1 of the refrigerator, an air flow channel (that is, the air duct 2 shown in the figure), a fan 3, The heating wire 4, the drying chamber 5, the small hole outlet 6 and the refrigerating chamber 7 are formed. Here the refrigerator is one of the aforementioned food storage devices. The freezing chamber 1 may be one of the aforementioned third storage chambers; and the drying chamber 5 may be one of the aforementioned first storage chambers. The small hole outlet 6 may correspond to a second guide channel of the second guide device in the aforementioned second guide device. The air flow channel 2 may be one of the first flow guiding channels of the first flow guiding device. The fan 3 may be a driving component of the first air guiding device. The heating wire 4 may be a type of a dehumidifying component. The refrigerating compartment 7 may correspond to the aforementioned third storage compartment.

The core functional components of the drying storage device of the present application are the airflow channel 2 and the fan 3, which can be embedded in the back of the refrigerator to play the role of introducing low-temperature and low-humidity air from the freezing chamber into the drying chamber.

When the drying function is turned on, the fan 3 is activated, and the low-temperature and low-humidity wind in the freezing chamber 1 is introduced into the drying chamber 5 through the airflow channel 2 and mixed with the originally humid air in the drying chamber 5. The drying chamber is provided with an outlet for multiple small holes Structure (can be replaced by another fan). Due to the fan's induced wind, the low humidity wind enters and mixes, and the higher humidity wind will be blown out. After a period of time, the drying room will reach a lower humidity, thereby achieving low humidity storage in the drying room. the process of. Depending on the storage items and the work of the user, the temperature and humidity in the drying room may change in various ways. For example, the temperature and humidity in the box are very high after the drawer is opened and the contents are placed in a high humidity. Happening. In this solution, a heating wire 4 is introduced at the bottom of the box to balance the temperature in the box, and the temperature and humidity in the box are reduced by turning on the fan. The control logic is designed for the above scenarios and the defrosting situation that may occur in the system.

For dehumidification in the refrigerating room, the most typical temperature and humidity need to be maintained at 5 ° C (commonly used in refrigerators). RH can be 30% (dry environment). The control logic block diagram can be shown in Figure 7. Referring to FIG. 7, it can be known that the entire control process is divided into four parts: other procedures, defrost and pretreatment procedures, defrost stopping procedures, and drying procedures. The other programs may be any program other than the drying program of a food storage device such as a refrigerator, for example, a cooling program, a frequency conversion program in a cooling program, and the like.

In Figure 7, according to parameters such as temperature (T), time (t), frequency (Hz), and relative humidity (RH), in other procedures, defrost and pretreatment procedures, after defrost procedures, and drying procedures. Switch between each other. The pre-processing program may be a pre-processing program for defrosting. The defrosting pretreatment procedure may include, but is not limited to, closing the air outlet of the food storage device, and / or making heating components such as a heating wire in a ready state. The procedure after stopping defrosting may include, but is not limited to, stagnant water removal procedures, for example, there may be stagnant water in the food storage device after defrosting, and the stagnant water is excluded from a predetermined position through the opening of the stagnant water removal channel.

The humidity of the defrosting process is guaranteed by sensing and pre-processing the defrosting cycle;

Through the evaluation of the temperature and humidity in the box, changing the other procedures of the refrigerator within a certain allowable range has never achieved unified control on the refrigerator and the drying system;

Consider three different schemes of joint control, individual control, and sensorless control;

Every interval (10min), the sensor in the drying box will sense the temperature and humidity in the drying room. When the temperature is higher than 6 ℃, the temperature is too high and the temperature needs to be reduced. At this time, the fan is turned on to induce low-temperature and low-humidity gas in the freezing room; when the temperature is lower than 4 At ℃, the temperature is too low at this time, no matter what the humidity is, the heater needs to be turned on to make certain compensation. When the relative humidity is lower than 30% of RH, no induced wind is needed to reduce the humidity. When the temperature meets the conditions, the lower humidity has less influence on the storage, which can be ignored. When the humidity is higher, the wind needs to be dehumidified and given a certain thermal compensation. When the temperature and humidity are all up to the standard, the entire process ends.

When the refrigerator starts to defrost, the humidity rises. This logic will jump out of this logic and directly close the induction process until the end of the defrost cycle and restart the above logic.

Example 2:

As shown in FIG. 8, in this example, the system of the food storage device detects the end of defrosting, and starts other programs. The other programs here may be one of the foregoing preset programs, for example, a stagnant water removal program or a defrost pre-program. Handlers, etc. Start the drying program within 10 minutes before and after the execution of other programs.

Figure 9 shows an optional drying program, including:

Determine that the temperature is within a preset temperature range (for example, less than or equal to 6 ° C and greater than or equal to 3 ° C);

If the temperature is within the preset temperature range, determine whether the relative humidity RH is within the preset humidity range (for example, RH is less than or equal to 30%). If so, close the air outlet and perform other procedures normally; if not, the air outlet is half open. The compressor is upshifted to accelerate refrigeration to condense out the moisture in the airflow in the food storage device.

If the temperature is less than the minimum temperature in the preset temperature range (for example, T is less than 3 ° C), determine whether RH is within the preset humidity range; if the RH is less than the minimum temperature in the preset humidity range, heat on, air outlet close, and perform other procedures ; If RH is greater than the highest temperature in the preset humidity range, heat up, the air outlet is half open, and the compressor is up one gear.

Under certain conditions, the determination of whether RH is within the preset humidity range can be skipped.

If the temperature is within the preset temperature range, determine whether the relative humidity is within the preset humidity range, for example, determine whether RH is greater than or equal to 10% and less than or equal to 30%; if the relative humidity is within the preset humidity range, Turn off the fan and turn off the heater; if the relative humidity is less than the minimum value of the preset humidity range, turn off the fan and turn off the heater; if the relative humidity is greater than the maximum value of the preset humidity range, turn on the fan and turn off the heater.
