Detailed Description
For meat and aquatic foods, the traditional fresh-keeping method mainly comprises two modes: a cold storage (4 ℃) fresh-keeping mode and a freezing fresh-keeping mode. The refrigerating and fresh-keeping mode has a certain inhibiting effect on microorganisms, but the fresh-keeping time for food materials is shorter. The freezing fresh-keeping mode is easy to enable the food material to generate ice crystals, the cell structure is damaged, the juice loss rate is high, the dry consumption and oxidation of the food material are accelerated, the nutrition loss of the food material is easy to cause when the food material is thawed, the freshness and the tenderness are reduced, and the fresh-keeping effect of the food material is poor.
Since the existing fresh-keeping technology of the refrigerator has the problems, the technical staff of the invention improves the existing fresh-keeping technology of the refrigerator.

Especially, when the temperature of the air in the refrigerator compartment is between-1.4 ℃ and-3.4 ℃ and the fluctuation temperature at each position in the compartment is not more than 0.8 ℃, the fresh-keeping effect of the refrigerator on food materials is more remarkable.
As shown in FIG. 3, the skilled person further finds that, for the food material newly placed in the compartment, the compartment is cooled to 0 ℃ to-1 ℃ at a rate of 30 min/DEG C to 220 min/DEG C, and then cooled to-1 ℃ to-1.1 ℃ at a rate of 230 min/DEG C to 520 min/DEG C, the food material after being refrigerated for 7 days is not frozen, and the content of microorganisms is low, i.e. the fresh-keeping effect of the food material is further improved.
As shown in fig. 4, the skilled person also finds that applying a magnetic field of 2mT to 10mT to the food material prolongs the freshness time of the food material.

In some embodiments of the invention, the current temperature of the target compartment 130 is obtained, including the current temperature of the target compartment 130 via the plurality of temperature sensors 140.
Alternatively, the current temperature may be an average value of the temperature values detected by all the temperature sensors 140, an average value of the temperature values detected by the temperature sensors 140 distributed at the top or bottom of the target compartment 130, or a temperature value detected by a specific temperature sensor 140.
Further, during different detection periods, a combination of different temperature sensors 140 may also be used to obtain the current temperature of the target compartment 130. For example, the current temperature of the target compartment 130 is detected by at least one temperature sensor 140 distributed at the bottom of the target compartment 130 during a stage in which the refrigerator 100 supplies air to the drawer assembly 120. At a stage when the refrigerator 100 stops supplying air to the drawer assembly 120, detecting a current temperature of the target compartment 130 by at least one temperature sensor 140 distributed at the top of the target compartment 130; alternatively, the current temperature of the target compartment 130 is determined by an average value detected by at least one temperature sensor 140 distributed at the top of the target compartment 130 and at least one temperature sensor 140 distributed at the bottom of the target compartment 130.
In step S120, in response to the current temperature being within the preset temperature range, the temperature at each position in the target compartment 130 is controlled within the preset temperature range, and the temperature fluctuation range at each position in the target compartment 130 is not greater than the first preset value, so that the uniformity of the temperature at all positions in the target compartment 130 is not greater than the second preset threshold.
Wherein, the larger the uniformity, the smaller the degree of dispersion of the temperature values between the positions in the inter-target chamber.
Specifically, the temperature value detected by each temperature sensor 140 is set within a preset temperature range, the temperature value detected by each temperature sensor 140 is set to be not greater than a first preset value, and the difference between the temperature value detected by each temperature sensor 140 and the average of the temperature values detected by all temperature sensors 140 is set to be not greater than a second preset threshold.
Wherein the preset temperature range is 0 ℃ to-4.4 ℃, preferably the preset temperature range is-1.4 ℃ to-3.4 ℃. Furthermore, the person skilled in the art can also set the preset temperature range to any other possible value range, for example 0 ℃ to-3.4 ℃, -1 ℃ to-4.4 ℃, -1.2 ℃ to-2.4 ℃, -1 ℃ to-3.2 ℃ etc., as desired.
Wherein the first preset threshold is 1.5 ℃, and further, the person skilled in the art can set the first preset threshold to any other feasible value, such as 1.0 ℃, 0.8 ℃, 0.5 ℃ and the like, according to the need.
Wherein the second preset threshold is 1 ℃. Furthermore, the person skilled in the art may also set the first preset threshold to any other feasible value, e.g. 0.9 ℃, 0.8 ℃, 0.6 ℃ etc., as desired.
Further, in order to bring the target compartment 130 to the temperature range described in step S120, the refrigerator 100 further includes a cool storage module 150 (shown in fig. 9) provided on a sidewall of the target compartment 130.
As shown in fig. 9, the top, bottom, and front sides (the side near the handle of the drawer 122) of the drawer 122 are provided with the cool storage module 150 so that the cool storage module 150 can slowly and uniformly discharge the cool to the target compartment 130. Alternatively, as required, the cold storage modules 150 may be disposed in the upper and lower, front and rear, and left and right directions of the drawer 122, so that the target compartment 130 in the drawer 122 may be uniformly cooled by the cold storage modules 150 at six sides of the drawer 122, thereby avoiding the food material in the target compartment 130 from being partially supercooled and frozen.
Alternatively, other cold storage modules 150 are provided on the outer tub 121 except that the cold storage module 150 on the front side of the drawer 122 is provided on the drawer 122.
Further, a person skilled in the art may further arrange a heat-conducting plate at the bottom side of the drawer 122 as required, so that the cold energy is absorbed by the heat-conducting plate first, and then is uniformly released into the drawer 122 through the heat-conducting plate, so as to uniformly cool the food material in the target compartment 130.
Based on the foregoing, it can be appreciated by those skilled in the art that in some embodiments of the present invention, by controlling the temperature at each location within the target compartment 130 to be within 0 ℃ to-4.4 ℃ and making the temperature fluctuation range at each location within the target compartment 130 not greater than 1.5 ℃, the uniformity at all locations within the target compartment 130 is not greater than 1 ℃, so that the temperatures at each location within the target compartment 130 are relatively low and nearly equal, thereby enabling the refrigerator 100 to uniformly cool the food within the target compartment 130, avoiding freezing of the food due to excessively low local temperatures.
A control method of a refrigerator in further embodiments of the present invention will be described in detail with reference to fig. 10.
As shown in fig. 10, in comparison with some embodiments described previously, in still other embodiments of the present invention, between step S110 and step S120, the control method of the refrigerator further includes:
in step S210, in response to the current temperature being greater than the first temperature, the target compartment 130 is cooled at a first rate to cool to the first temperature.
Wherein the value of the first temperature ranges from-1.0 to 1.0 ℃. Specifically, the first temperature may be-1.0 ℃, -0.5 ℃, 0 ℃, 0.5 ℃, 1.0 ℃, etc.
Wherein the first rate has a value in a range of 30 min/. Degree.C.to 220 min/. Degree.C.e., 30 min/. Degree.C.45 min/. Degree.C.80 min/. Degree.C.150 min/. Degree.C.180 min/. Degree.C.200 min/. Degree.C.220 min/. Degree.etc.
In response to the current temperature being not greater than the first temperature and greater than the second temperature, the target compartment 130 is cooled at a second rate to cool to the second temperature S220.
Wherein the second rate is less than the first rate and the second rate has a value ranging from 230min/°c to 520min/°c, e.g., 230min/°c, 250min/°c, 300min/°c, 320min/°c, 400min/°c, 500min/°c, 520min/°c, and the like.
Wherein the second temperature is less than the first temperature, and the value of the second temperature ranges from-1.0 ℃ to-2.0 ℃. In particular, the second temperature may be-1.0 ℃, -1.5 ℃, 1.8 ℃, -2.0 ℃ and the like.
It can be appreciated by those skilled in the art that in still other embodiments of the present invention, by rapidly cooling the target compartment 130 to the first temperature at the first rate, then slowly cooling to the second temperature at the second rate, and finally floating the temperature in the target compartment 130 within the predetermined temperature range, the effects of food preservation are avoided when the food is slowly cooled, and freezing occurs when the temperature is too fast. Therefore, further embodiments of the invention overcome the adverse effect on the fresh-keeping effect of the food material in the cooling stage of the food material, and improve the fresh-keeping effect of the food material.
Further embodiments of the present invention are described in detail below with reference to fig. 11.
In other embodiments of the present invention, the refrigerator 100 further includes a magnetic field generating module that generates a magnetic field capable of covering various positions of the target compartment 130, as compared to any of the embodiments described above.
Further, the control method of the refrigerator further includes the steps of: the magnetic field module 160 is caused to provide a magnetic field having a magnetic field strength of 2mT to 10mT to the target compartment 130.
The magnetic field strength provided by the magnetic field module 160 to the target compartment 130 may be any feasible value, such as 2mT, 3mT, 3.4mT, 5mT, 8mT, 10mT, etc.
In other embodiments of the present invention, the magnetic field provided by the magnetic field module 160 to the target compartment 130 may be a magnetic field having a constant magnetic field strength or a magnetic field having a varying magnetic field strength.
As will be appreciated by those skilled in the art, since the response speed of the magnetic field is much faster than the response speed of the temperature change, and the magnetic field has a fresh-keeping effect on the food, in order to optimize the fresh-keeping effect of the food, when the magnetic field module 160 provides the target compartment 130 with a magnetic field having a varying magnetic field strength, the magnetic field strength increases with an increase in the temperature of the target compartment 130, and decreases with a decrease in the temperature of the target compartment 130. So that the refrigerator 100 can have a good fresh-keeping effect and also reduce the energy consumption of the refrigerator 100.
It will be appreciated by those skilled in the art that in other embodiments of the present invention, the magnetic field module 160 provides the magnetic field with the magnetic field strength of 2mT to 10mT to the target compartment 130, so that the refrigerator 100 can keep food fresh under the dual actions of the magnetic field and the low temperature, thereby prolonging the fresh time of the food.
Further embodiments of the present invention are described in detail below with reference to fig. 12-16.
In still other embodiments of the present invention, as compared with any of the previous embodiments, the control method of the refrigerator further includes, prior to step S110: it is detected whether or not food is placed in the target compartment 130.
And, step S110 specifically includes: in response to the food material being placed in the target compartment 130, a current temperature of the target compartment 130 is obtained.
In still other embodiments of the present invention, any feasible manner may be used to detect whether food material is placed in the target compartment 130, and the manner in which whether food material is placed in the target compartment 130 will be described below by way of example.
As example one:
as shown in fig. 13, the drawer assembly 120 further includes an infrared emission module 1251 and an infrared receiving module 1252, the infrared emission module 1251 and the infrared receiving module 1252 being disposed opposite each other on both sides of the drawer 122. After food is placed in the drawer 122, the food may affect the infrared signal received by the infrared receiving module 1252, so that the intensity of the infrared signal received by the infrared receiving module 1252 is weakened. Therefore, when the refrigerator 100 detects that the intensity of the infrared signal received by the external receiving module is weakened, it can be determined that the food material is placed in the target compartment 130.
As example two:
as shown in fig. 14, the drawer assembly 120 further includes a load cell 126 disposed between the outer tub 121 and the drawer 122, the load cell 126 being configured to detect the weight of the drawer 122 such that the refrigerator 100 determines whether food material is placed in the target compartment 130 by the weight weighed by the load cell 126.
As an example three:
as shown in fig. 15 and 16, the drawer assembly 120 further includes a first rail 127, a second rail 128, and a pressure sensor 129. The front portion of the outer cylinder 121 is provided with a slide rail stopper 1211, and the slide rail stopper 1211 may be any feasible structure, such as a bump protruding from the surface of the outer cylinder 121, a stopper or a column fixedly connected to the outer cylinder 121. The rear portion of the first slide rail 127 is pivotally connected to the rear portion of the outer cylinder 121, and the front portion of the first slide rail 127 is located on the upper side of the slide rail stopper 1211. The second slide rail 128 is provided on the outer cylinder 121 and is slidably connected to the first slide rail 127. The pressure sensor 129 is provided on the slide rail stopper 1211, and the pressure sensor 129 can abut against the front portion of the first slide rail 127.
Fig. 15 shows a schematic view in which the second slide rail 128 abuts against the pressure sensor 129 when the drawer 122 is in the inserted state. In this state, the pressure sensor 129 receives the pressure of the drawer 122. Fig. 16 shows a schematic view in which the second slide 128 is separated from the pressure sensor 129 when the drawer 122 is in the drawn-out state. At this time, the pressure sensor 129 is not affected by the pressure of the drawer 122.
In this example, detecting whether food material is placed in the target compartment 130 includes:
in step S310, whether the value detected by the pressure sensor 129 is dynamically changed is detected to determine whether the drawer 122 is drawn out by the user.
In step S320, if yes, the current value detected by the pressure sensor 129 is compared with the value before dynamic change to determine whether food is placed in the drawer 122.
In step S330, if the current value is greater than the value before dynamic change, it is determined that food is placed in the target compartment 130.
As will be appreciated by those skilled in the art, in this example, by providing the pressure sensor 129 at the rail stop 1211 on the front of the outer barrel 121 and pivotally connecting the rear of the first rail 127 to the rear of the outer barrel 121, the front of the first rail 127 can selectively abut the pressure sensor 129 and thus allow the drawer 122 to exert a certain pressure on the pressure sensor 129 whether the center of gravity is located at the front, middle or rear thereof, thereby ensuring the reliability of the pressure sensor 129 in detecting weight changes of food materials within the drawer 122. Further, it is determined whether the drawer 122 is drawn out by the user by detecting whether the value detected by the pressure sensor 129 is dynamically changed; and when the value detected by the pressure sensor 129 is determined to be dynamically changed, the current value detected by the pressure sensor 129 is compared with the value before dynamic change to determine whether food is put into the drawer 122, so that the reliability of the pressure sensor 129 on the weight detection of the drawer 122 is ensured.
In this example, compared to example one, example three avoids a smaller volume of food material, and when the infrared receiving module 1252 receives an infrared signal without affecting it, the infrared receiving module 1252 cannot detect that food material is placed in the drawer 122.
In this example, compared to example two, example three avoids the inability to trigger the detection function of load cell 126 when the food material is biased.
As shown in fig. 17, the refrigerator 100 of the present invention further includes a control module 170, the control module 170 including a processor 171, a memory 172, and execution instructions stored on the memory 172, the execution instructions being configured to enable the refrigerator 100 to perform the control method described in any of the previous embodiments when executed by the processor 172.
Thus far, the technical solution of the present invention has been described in connection with the foregoing embodiments, but it will be readily understood by those skilled in the art that the scope of the present invention is not limited to only these specific embodiments. The technical solutions in the above embodiments can be split and combined by those skilled in the art without departing from the technical principles of the present invention, and equivalent changes or substitutions can be made to related technical features, so any changes, equivalent substitutions, improvements, etc. made within the technical principles and/or technical concepts of the present invention will fall within the protection scope of the present invention.
