Description

However, when the refrigerator control is performed using this control method, when the temperature measured by the temperature sensor is higher than a preset value, the refrigerator compartment starts cooling. In the case where the refrigerator compartment is divided into a plurality of relatively independent storage spaces by the shelf partition, the temperature in the storage space just placed in the article may be higher than other storage spaces, and the existing refrigerator temperature control method is required. The entire refrigeration compartment is cooled, resulting in wasted electric energy, especially in the case of a large volume of the refrigerating compartment.

During this process, the temperature of the item may be transmitted to other items in contact with it, resulting in a change in the temperature of the stored food in the refrigerator, resulting in loss of nutrients and a decrease in storage effect.

The refrigerator includes a casing 310. The casing 310 defines a refrigerator compartment therein. The casing 310 includes a top wall and a bottom wall. The rear wall and the left and right side walls are enclosed, and the door body is disposed in front of the box body 310, and the door body can be connected to the side wall by a pivot structure.

The rack assembly 320 divides the refrigerating compartment into a plurality of storage spaces. One preferred configuration is that the rack assembly 320 includes at least one horizontally disposed partition to divide the refrigerating compartment into a plurality of storage spaces in a vertical direction. In FIG. 2, the rack assembly 320 divides the refrigerating compartment into a first storage space 341, a second storage space 342, and a third storage space 343. In other embodiments of the invention, the number of partitions in the rack assembly 320 and the amount of storage space may be pre-configured according to the volume of the refrigerator and the requirements for use.

The volume detecting device 330 includes at least one detecting component. The detecting component is disposed in the refrigerating chamber for emitting an optical signal and detecting the optical signal. These optical signals include visible light and infrared light. Each detection component includes at least: a visible light source, an infrared light source, and a light sensing device. The visible light source is configured to emit visible light into the interior of the refrigeration compartment. The infrared light source is configured to emit infrared light into the interior of the storage compartment. The light sensing device is configured to detect the intensity of visible light and the intensity of infrared light at the location where the detection component is located. The number of detection components can be determined according to the volume and structure of the refrigerating compartment. In FIG. 2, the volume detecting device 330 shown is provided with a detecting assembly in each of the first storage space 341, the second storage space 342, and the third storage space 343.

With the change in the use size of the refrigerating compartment, the reflection and occlusion of visible light and infrared light in the storage space change, and the propagation characteristics of visible light and infrared light also differ, after the inventor's summary and test The law of the change of visible light intensity and infrared light intensity with the change of the volume of use is summarized, so that the optical volume principle is used to detect the volume of the refrigerator.

In addition, the above visible light source can also be replaced by an illumination source of the refrigerating compartment, so that the illumination source can be used as a light source for visible light in volume calculation in addition to providing illumination for the user. In this case, the brightness of the illumination source needs to meet the requirements for volume detection.

When the plurality of detecting components are plural, the plurality of detecting components are distributed inside the peripheral wall of the refrigerating compartment, and the line connecting the center points of any two detecting components placed on the same plane of the peripheral wall and the other planes intersecting the plane in the peripheral wall are required. The angles are not 0 degrees or 90 degrees; the angle between the line connecting the center points of any two detecting components disposed on different planes of the peripheral wall and the horizontal plane or the vertical plane is not 0 degrees or 90 degrees.

The closing signal of the above refrigerating compartment may be generated by the door sensing device according to the switching condition of the door body.

An example in which the three detection assemblies shown in FIG. 2 are respectively disposed on three sides of the side wall for volume detection describes a flow for calculating the storage space usage volume. According to the positional relationship of the three detecting components in the vertical direction, the detecting component in the first storage space 341 is recorded as the first detecting component, and the detecting component in the second storage space 342 is recorded as the second detecting component. The detection component in the three storage space 343 is referred to as a third detection component. The specific algorithm for calculating the volume of use of each storage space according to the intensity of visible light and the intensity of infrared light can be:

The calculation of the used volume of the storage space of the detection target includes: estimating the volume of the storage interval of the detection target according to Equation 1:

Formula 1: Vn'=SnA×kn,

In Equation 1, n is the sequence number of the detection component in the storage space of the detection target, Vn' is the estimated value corresponding to the nth detection component, and SnA is the visible light intensity value detected by the nth detection component, kn is the nth The visible light estimation coefficient of the detection component;

The estimated Vn' is corrected according to Equation 2:

Formula 2: Vn=Vn'+∑Smp×Mmn;

In Equation 2, m is the serial number of the detection component adjacent to the detection component in the storage space of the detection target in the vertical direction, m is n-1 and/or n+1, and SmA is the mth detection The visible light intensity obtained by the component detection, Mmn is the calculated correction factor of the mth detecting component 100 for the nth detecting component, which is calculated according to formula 3:

Equation 3: Mmn = (Smp × Jmn) / (SmA × Tmn),

In Equation 3, Smp is the intensity of the infrared light detected by the mth detection component, Jmn is the infrared detection constant of the mth detection component for the nth detection component, and Tmn is the infrared detected by the mth detection component. The distance value corresponding to the light intensity. Kn And Jmn is a constant pre-stored in the refrigerator, and is obtained by pre-test statistics.

For the first detecting component, the detecting component adjacent in the vertical direction is the second detecting component, and the usage volume of the corresponding first storage space 341 is:

V1 = S1A × k1 + S2A × ((S2P × J21) / (S2A × T21)).

For the second detecting component, the detecting components adjacent in the vertical direction are the first detecting component and the third detecting component, and the usage volume of the corresponding second storage space 342 is:

V2 = S2A × k2 + S1A × ((S1P × J12) / (S1A × T12)) + S3A × ((S3P × J32) / (S3A × T32)).

For the third detecting component, the adjacent detecting component in the vertical direction is the second detecting component, and the usage volume of the corresponding third storage space 343 is:

V3 = S3A × k3 + S2A × ((S2P × J23) / (S3A × T23)).

The above detection principle is that visible light can pass through the glass at equal intervals and is irradiated throughout the refrigerating chamber, and generally infrared light cannot pass through the glass at equal intervals.

The above volume detection process can be performed after each refrigerator compartment door is closed, and the volume change amount of each storage space after each door closing can be calculated according to the history, and is respectively recorded as ΔV1, ΔV1, ΔV3.

An optional configuration manner is that the time determining module 120 calculates the amount of change in the usage volume of each storage space before and after the refrigerator compartment is closed according to the usage volume of each storage space; the volume change is used according to a preset conversion algorithm. The amount is converted into the fast cooling running time increment; the rapid cooling running time increment of each storage space is accumulated with the uncompleted fast cooling running time to obtain the required rapid cooling running time of each storage space. An optional way to convert the volume change into a fast cooling run time increment is: the fast cooling run time increment is equal to the product of the volume change and the preset factor, the preset factor is a constant, according to The specific conditions of the refrigerator freezer are pre-tested and summarized.

The first cold source drive module 130 can be configured to drive the cold source to operate in a rapid cooling mode, wherein in the fast cooling mode, both the refrigerating fan and the compressor in the cold source operate at a higher speed than the normal cooling mode to release more The amount of cold makes the newly placed items cool down quickly. Before the startup of the first cold source driving module 130, the time determining module 150 may further determine whether the required fast cooling running time of each storage space is greater than zero; and the first cold source driving module 130 exists in any one of In the case where the required rapid cooling run time of the storage space is greater than zero, the step of driving the cold source to operate in the fast cooling mode is performed.

When the judgment result of the time judging module 150 is that the required rapid cooling running time of the plurality of storage spaces is less than or equal to zero, the second cold source driving module 160 drives the cold source to operate in the normal cooling mode.

The temperature judging module 190 may be configured to: after driving the cold source to operate in the fast cooling mode, acquire an average temperature of the refrigerating chamber environment sensed by the refrigerating environment temperature sensing device; and determine whether the average temperature of the refrigerating chamber environment is less than a preset first refrigerating temperature Turning off the temperature threshold; if the indoor ambient temperature is greater than or equal to the preset first cooling off temperature threshold, driving the split air supply device to provide a state of simultaneously providing cooling airflow to the plurality of storage spaces; Whether the temperature is less than a preset first cooling off temperature threshold, and further determining whether the average ambient temperature in the refrigerating compartment is less than a preset second cooling off temperature threshold, wherein the second cooling off temperature threshold is less than the first cooling off temperature threshold; Whether the ambient average temperature is less than a preset second cooling off temperature threshold, stopping the split air supply device to distribute the cooling airflow to the plurality of storage spaces; and if the indoor ambient average temperature is greater than a preset second cooling off temperature threshold, Start the air supply unit drive module to perform as fast as Cooling operation time setting step of cooling the storage space status identified.

The air blowing device driving module 140 may be configured to set the cooling state indicator of the storage space according to the rapid cooling running time, and drive the bypass air blowing device to operate to provide a state of cooling airflow to the storage space indicated by the cooling state to be activated. In an optional configuration method, the blower drive module 140 can subtract the consumed time from the required rapid cooling run time of each storage space to obtain the remaining rapid cooling run time of each storage space. Set the cooling status ID of the storage space with the remaining fast cooling run time greater than zero to start. Since the above control flow is executed cyclically, the time consumed above is generally a cycle of program execution.
