Description

Fresh-keeping refrigerator, working method thereof, electronic equipment and storage medium

Technical Field

The application relates to the technical field of food preservation, in particular to a preservation refrigerator, a working method thereof, electronic equipment and a storage medium.

Background

Common fresh meat preservation methods generally comprise refrigeration, soft freezing and freezing, wherein the refrigeration and preservation time is short, and the frozen meat has poor taste and needs thawing, so the soft freezing is a more suitable meat preservation method. The soft freezing can prolong the fresh-keeping period of the meat to 1-2 weeks, and the nutrition loss of the meat is less, and the meat can be processed later without thawing. However, the existing soft freezing technology has a certain problem that the refrigerator refrigerating system conveys low-temperature air to the soft freezing area to take away heat, so that the whole soft freezing area and the stored meat are reduced to a preset temperature. In the process, the low-temperature air humidity is lower, so that the internal humidity of a soft freezing area is reduced, the surface air drying is caused when cold air directly contacts unpacked meat, the loss of the dry loss is caused when the meat is stored for a long time, the appearance of the meat is deteriorated, and the deterioration process of food is accelerated.

Therefore, related technologies propose to use indirect refrigeration and a mode that cold air is not directly blown to refrigerate a soft freezing area, the scheme can effectively avoid the problem of loss of dry consumption caused by direct blowing of cold air, but still can generate new problems in the long-term use process, when a user opens the soft freezing area to access meat each time, as the internal temperature is lower than the external air temperature, moisture in the external air can enter the soft freezing area and accumulate and condense in the soft freezing area for a long time. And because the soft freezing area is below zero, the frost and ice formation of the refrigerator similar to direct cooling can occur in the compartment. The refrigerating efficiency is reduced after frosting and icing, and the drawer is difficult to open when serious, so that inconvenience is brought to users. Moreover, when the user opens the soft freezing area to store meat each time, the internal temperature also rises, but the refrigerating speed of indirect refrigeration is lower, and the surface of the stored meat can be melted and thawed, and repeated temperature fluctuation can also cause recrystallization of the meat, so that the fresh-keeping effect of soft freezing on the meat is reduced. The frozen area for storing meat for a long time is generally frozen at the temperature of-18 ℃ or lower, and the temperature of the frozen area is generally controlled by adopting an air cooling mode, so that the frozen area also has the problems of low environmental humidity and easy occurrence of dry consumption of the meat.

This scheme is for solving above-mentioned problem, through setting up special passageway (like electronic air door) between soft freezing region and freezer, makes two regions can take place heat and moisture transfer when the passageway is opened to open and close through control channel, realize in the soft freezing region unnecessary moisture in time discharge to the freezer, and make the temperature reduce fast under the air convection of freezer. Meanwhile, the water can be supplemented for the freezing chamber, so that the humidity of the freezing chamber is improved to a certain extent, and the dry consumption condition of the freezing chamber is reduced.

The fresh-keeping refrigerator comprises a refrigeration module and a communication channel 6, wherein the refrigeration module comprises an air cooling system and a cold guide structure arranged in the soft freezing compartment 103.

The air cooling system is configured to control the temperature within the freezer compartment 102 in an air-cooled manner. The evaporator chamber 107 communicates with the freezer compartment 102 via a supply air duct, and the freezer compartment 102 communicates with the evaporator chamber 107 via a return air duct. The evaporator chamber 107 is internally provided with the evaporator 3, the air flow in the evaporator chamber 107 and the evaporator 3 exchange heat to form a refrigerating air flow, the fan 4 can drive the air flow in the evaporator chamber 107 to flow into the air supply duct and then drive the air flow to flow in the air supply duct, the refrigerating air flow in the air supply duct enters the freezing chamber 102 for exchanging heat, the temperature in the freezing chamber 102 is reduced to the target temperature, and the air flow in the freezing chamber 102 can continue to pass through the air outlet duct and finally returns to the evaporator chamber 107, so that the circulation of the air flow is completed.

Specifically, the air cooling system is configured to cool the cold guide structure, in the working process, the air flow in the evaporator cavity 107 exchanges heat with the evaporator 3 to form a cooling air flow, the fan 4 drives the cooling air flow in the evaporator cavity 107 to exchange heat with the cold guide structure, the cooling capacity is transferred to the cold guide structure, and the air flow after heat exchange continuously enters and returns to the evaporator cavity 107 to complete circulation of the air flow. The cold-conducting structure for obtaining cold energy continuously transmits the cold energy to the soft freezing chamber 103 in a direct cooling mode, so that the aim of controlling the temperature in the soft freezing chamber 103 is fulfilled.

The communication channel 6 of the fresh-keeping refrigerator is located in the box body 1, specifically, the communication channel 6 is arranged in a heat insulation foaming layer between the soft freezing chamber 103 and the freezing chamber 102, two ends of the communication channel 6 are respectively communicated with the freezing chamber 102 and the soft freezing chamber 103, and a first air door 7 for controlling the opening and closing of the communication channel 6 is arranged in the communication channel 6. When the first air door 7 is opened, the communication passage 6 is opened, and the freezing compartment 102 and the soft freezing compartment 103 are communicated through the communication passage 6; when the first damper 7 is closed, the communication passage 6 is closed, and the freezing chamber 102 and the soft freezing chamber 103 cannot communicate through the communication passage 6.

In the above embodiment, when the soft-freezing door 106 is closed, the whole soft-freezing compartment 103 forms a relatively sealed space, and the cold-conducting structure is located inside the soft-freezing compartment 103 and exchanges heat with the soft-freezing compartment 103 in a direct-cooling manner, so that the temperature of the inside and stored articles in the soft-freezing region is reduced to a preset temperature, and the problems of low humidity and loss of dry consumption of the articles caused by direct blowing of cold air can be effectively avoided.

In another use scenario, each time a user opens the soft freeze compartment 103 to access an item, moisture in the outside air may enter the soft freeze compartment 103 and accumulate in the soft freeze compartment 103 for a long period of time and generate condensation because the inside temperature of the soft freeze compartment 103 is lower than the outside air temperature. And because the soft freezing chamber 103 is below zero, condensation can appear in the interior of the soft freezing chamber 103 like frosting and icing of a direct-cooling refrigerator. The refrigerating efficiency in the soft freezing compartment 103 is reduced after frosting and icing, and the drawer in the soft freezing compartment 103 is difficult to open when severe, so that inconvenience is brought to a user. Moreover, when the user opens the soft-freezing compartment 103 to access the articles each time, external heat can enter the soft-freezing compartment 103, the temperature in the soft-freezing compartment 103 can also rise, the direct cooling mode of the cold conduction structure has lower refrigerating speed, the surface of the stored food can be melted and thawed, repeated temperature fluctuation can also cause recrystallization of meat, so that the fresh-keeping effect of soft freezing on the meat is reduced, and the direct cooling refrigeration by adopting the cold conduction structure can not reduce the humidity in the soft-freezing compartment 103.

In the above embodiment of the present application, by providing the communication channel 6 between the soft freezing chamber 103 and the freezing chamber 102, heat and moisture transfer can occur when the soft freezing chamber 103 and the freezing chamber 102 are opened by controlling the opening and closing of the communication channel 6, so that excessive moisture in the soft freezing chamber 103 is timely discharged to the freezing chamber 102, and the temperature in the soft freezing chamber 103 is rapidly reduced under the air convection, thereby achieving the purpose of reducing the temperature and the humidity in the soft freezing chamber 103. It should be noted that, the working scenario of the communication channel 6 is that after the soft freezing compartment 103 of the fresh-keeping refrigerator is opened, the temperature and humidity in the soft freezing compartment 103 are raised, heat and humidity exchange is established between the soft freezing compartment 103 and the freezing compartment 102 by means of the communication channel 6, and when the soft freezing compartment 103 stably operates in a daily closed state, the internal humidity of the soft freezing compartment 103 does not have large fluctuation, and the daily temperature in the soft freezing region is maintained by means of the cold conducting structure of the refrigerating module in the scenario.

In some embodiments, the soft freeze compartment 103 is located above the freeze compartment 102, and the communication channel 6 is used to guide the condensation in the soft freeze compartment 103 to flow into the freeze compartment 102 by gravity. The freezing chamber 102 for storing frozen food for a long time is generally frozen at a temperature of-18 ℃ or lower, and the temperature of the freezing chamber 102 is controlled by adopting an air cooling mode, so that the problems of low environmental humidity and easy food dry consumption exist in the freezing chamber 102. In this embodiment, when the user opens the soft-freezing compartment 103 to access the articles each time, since the temperature inside the soft-freezing compartment 103 is lower than the temperature of the outside air, moisture in the outside air enters the soft-freezing compartment 103 and accumulates in the soft-freezing compartment 103 for a long period of time to generate condensation, and the communication channel 6 guides the condensation in the soft-freezing compartment 103 to flow into the freezing compartment 102 by gravity, so that the freezing compartment 102 can be replenished with water, the humidity of the freezing compartment 102 is raised to a certain extent, and the dry consumption of food in the freezing compartment 102 is reduced.

In some embodiments, the cold-conducting structure is a soft-freezing air duct 5, and the cold air generated by the air cooling system can circulate in the soft-freezing air duct 5. The soft freezing air duct 5 stretches into the soft freezing compartment 103, cold air from the refrigerating system can pass through the soft freezing air duct 5 to take away heat in the soft freezing compartment 103, when the soft freezing compartment 103 needs to be refrigerated, the soft freezing air duct 5 is opened, the air cooling system is opened, cold air generated by the air cooling system can continuously circularly flow in the soft freezing air duct 5, the inside of the soft freezing compartment 103 and stored articles are reduced to a preset temperature in a heat conduction mode of the wall surface of the soft freezing air duct 5, and therefore refrigeration is achieved in a mode of adopting cold air to not directly blow, the dry consumption of the stored meat in the soft freezing compartment 103 is reduced, and the fresh-keeping effect of the soft freezing compartment 103 is improved. In order to conveniently realize the opening or closing of the soft freezing air duct 5, a second air door 8 is arranged between the soft freezing air duct 5 and the air cooling system, when the second air door 8 is opened, the soft freezing air duct 5 is communicated with the air cooling system, cold air generated by the air cooling system can enter the soft freezing air duct 5 for internal circulation, and when the second air door 8 is closed, the soft freezing air duct 5 is not communicated with the air cooling system, and cold air generated by the air cooling system cannot enter the soft freezing air duct 5.

In some embodiments, the shape of the soft-freezing air duct 5 in the soft-freezing compartment 103 includes, but is not limited to, linear type, U-shape and serpentine shape, the soft-freezing air duct 5 is set to be U-shape and serpentine shape, so that the effective length of the soft-freezing air duct 5 in the soft-freezing compartment 103 can be increased, the heat exchange area is increased, the serpentine structure can increase the wind resistance of the inside, the soft-freezing air duct 5 is set to be U-shape in the soft-freezing compartment 103 under the condition of considering both the heat exchange area and the wind resistance, and the soft-freezing air duct 5 is set as close to the wall surface of the soft-freezing compartment 103 as possible, so as to reduce the occupation of the soft-freezing air duct 5 to the storage space in the soft-freezing compartment 103.

In some embodiments, a first temperature sensor is disposed within the soft freeze compartment 103 for acquiring the temperature within the soft freeze compartment 103 in real time and a humidity sensor is disposed within the soft freeze compartment 103 for acquiring the humidity within the soft freeze compartment 103 in real time. A second temperature sensor is disposed in the freezing chamber 102, and the second temperature sensor is used for collecting the temperature in the freezing chamber 102 in real time. The temperature and humidity in the soft freeze compartment 103, as well as the temperature in the freezer compartment 102, can be monitored in real time by the first temperature sensor, the second temperature sensor and the humidity sensor.

Based on the same technical conception, the application also provides a working method of the fresh-keeping refrigerator, and the working method is applied to the fresh-keeping refrigerator in the previous embodiment of the application. As shown in fig. 2, the working method of the fresh-keeping refrigerator includes:

step 1, after the soft freezing compartment is monitored to be opened, monitoring whether the soft freezing compartment is closed or not in real time;

step 2, when the soft freezing compartment is closed, acquiring the temperature in the soft freezing compartment as a first temperature T1, acquiring the humidity in the soft freezing compartment as a first humidity H1, and acquiring the temperature in the freezing compartment as a second temperature T0;

step 3, the air cooling system controls the temperature in the freezing compartment to be reduced from the second temperature T0 to a third temperature T2;

and 4, controlling the opening and closing of the communication channel and the opening and closing of the soft freezing air duct to enable the temperature in the soft freezing chamber to reach a preset temperature T0 and the humidity in the soft freezing chamber to reach a preset humidity H0.

When a user accesses an article by opening the soft freeze compartment 103 each time, moisture in the outside air may enter the soft freeze compartment 103 and accumulate in the soft freeze compartment 103 for a long period of time and generate condensation because the inside temperature of the soft freeze compartment 103 is lower than the outside air temperature. Further, each time the user opens the soft freeze compartment 103 to access the article, external heat is introduced into the soft freeze compartment 103, and the temperature in the soft freeze compartment 103 is also increased. In the above embodiment, the information of opening and closing the door of the soft freezing compartment is obtained through the step 1, and is used as the trigger condition for starting the working method of the fresh-keeping refrigerator in the embodiment of the application; in the step 2, after the soft freezing chamber of the refrigerator is subjected to door opening and closing, at the moment of door closing, a first temperature T1 and a first humidity H1 in the soft freezing chamber and a second temperature T0 in the freezing chamber are obtained, wherein the first temperature T1 and the first humidity H1 are used for evaluating the deviation of the temperature and the humidity in the current soft freezing chamber relative to a preset value, and the second temperature T0 in the freezing chamber is used for evaluating the potential of the freezing chamber for providing cold energy for the soft freezing chamber and providing basic data for cold energy regulation in the subsequent step; in step 3, after the user opens the soft freezing compartment to access the articles each time, when the soft freezing compartment is closed, the air cooling system simultaneously starts to refrigerate and cool the freezing compartment, and the process is used for storing the cold quantity so as to ensure that the freezing compartment can still be maintained in a normal temperature range after the subsequent freezing compartment transfers the cold quantity to the soft freezing compartment; in step 4, after the refrigeration of the freezing compartment is completed, the first air door in the communication channel is opened, so that the cold in the freezing compartment is convected to the soft freezing compartment, meanwhile, the water in the soft freezing region can be discharged into the freezing compartment, and the soft freezing compartment can be further cooled by starting the soft freezing air duct under the condition that the temperature is not up to standard until the temperature and the humidity level in the soft freezing compartment reach preset values, thereby realizing the rapid cooling and dehumidification of the soft freezing compartment, improving the fresh-keeping effect of the soft freezing compartment, supplementing water to the freezing compartment to a certain extent, and improving the fresh-keeping effect of the freezing compartment.

It should be noted that, the method relies on the fresh-keeping refrigerator in the foregoing embodiment of the present application to implement, by setting the communication channel 6 between the soft freezing compartment 103 and the freezing compartment 102, heat and moisture transfer can occur when the communication channel 6 is opened in the soft freezing compartment 103 and the freezing compartment 102, and by controlling the opening and closing of the communication channel 6, excessive moisture in the soft freezing compartment 103 is timely discharged to the freezing compartment 102, and the temperature in the soft freezing compartment 103 is rapidly reduced under the air convection, thereby achieving the purpose of reducing the temperature and the humidity in the soft freezing compartment 103.

In the foregoing embodiment, the working scenario of the working method of the fresh-keeping refrigerator is that after the soft-freezing compartment 3 of the fresh-keeping refrigerator is opened, the temperature and the humidity in the soft-freezing compartment are raised, and the heat and the humidity exchange is established between the soft-freezing compartment and the freezing compartment by means of the communication channel, so step 1 is a trigger condition of the working method of the embodiment, when the soft-freezing compartment is stably operated in a daily closed state, the internal humidity of the soft-freezing compartment does not have large fluctuation, and the daily temperature in the soft-freezing area is maintained by means of the cold conducting structure of the refrigerating module in the scenario without adopting the working method.

In some embodiments, the third temperature T2. Ltoreq.t0- (T1-T0). According to the heat transfer formulaWhere K represents a heat transfer coefficient, a represents a heat transfer area, Δt represents a temperature difference, and Δd represents a heat transfer distance. Assuming no heat loss in the heat transfer process, the temperature changes of the soft freezing chamber and the freezing chamber are the same in the heat transfer process, namely the temperature change value of the temperature decrease of the soft freezing chamber is equal to the temperature change value of the temperature increase of the freezing chamber, namely the temperature of the soft freezing chamber is decreased from the first temperature T1 to the preset temperature after the communication channel is openedAfter setting the temperature T0, the temperature of the freezing chamber is just increased from T0- (T1-T0) to a second temperature T0, wherein the second temperature T0 is the normal working temperature of the freezing chamber, and the third temperature T2 _＝ T0- (T1-T0). Because there is some heat loss during the heat transfer process, it is considered that the third temperature is set to be t2+.t0- (T1-T0) during the actual control process, so that sufficient cooling capacity can be provided for the soft-freezing compartment through the freezing compartment, so that the temperature in the soft-freezing compartment is raised to the preset temperature T0, and the temperature in the freezing compartment can be maintained at the second temperature T0.

In some embodiments, the controlling the opening and closing of the communication channel and the opening and closing of the soft-freezing air duct, so that the temperature in the soft-freezing chamber reaches the preset temperature T0, and the process that the humidity in the soft-freezing chamber reaches the preset humidity H0 includes: controlling the soft freezing air duct to be closed, and opening the communication channel, wherein the temperature and the humidity in the soft freezing compartment are reduced; and determining whether the soft freezing air duct is opened or not based on the priority degree that the temperature in the soft freezing room reaches the preset temperature T0 and the humidity in the soft freezing room reaches the preset humidity H0.

Because after the soft freezing chamber is opened by a user, the temperature and the humidity of the changeable external environment are affected, after the soft freezing chamber is closed, the change degree of the temperature and the humidity in the soft freezing chamber can be different in the operation process of different times, and the temperature and the humidity in the freezing chamber are not constant, although the freezing chamber is kept in a low-temperature and low-humidity state relative to the soft freezing chamber, after the communication channel is opened, the temperature and the humidity in the soft freezing chamber can be quickly reduced, but which of the two indexes firstly reaches the preset value is different under different working conditions, and the two indexes also hardly reach the preset value at the same time, if the first index firstly reaches the preset value and then keeps the communication channel continuously opened for the second index to be reduced to the preset value, the first index is lower than the preset value after the second index reaches the preset value, the influence is caused on the control parameter in the soft freezing chamber, and the food preservation is unfavorable.
