The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the invention and structural, methodological, or functional modifications of these embodiments that may be made by one of ordinary skill in the art are included within the scope of the invention.

The refrigeration device 10 of the present embodiment may be a refrigerator, a freezer, a wine cabinet, etc., and the following embodiments take a home appliance-freezer applied in a home environment as an example, and describe a freezing control method in the environment of the freezer, so as to achieve a better freezing effect on food materials.

The refrigeration equipment 10 comprises a refrigeration compartment for refrigerating food materials, a food material temperature detection module 4 for acquiring the temperature of the food materials, and a refrigeration system for refrigerating the food materials.

Fig. 1 is a block diagram of a method for controlling freezing according to an embodiment of the present application, and although the present application provides the method operation steps according to the following embodiment or flowchart, the method is not logically limited to the execution sequence provided in the embodiment of the present application, based on conventional or non-creative labor, among steps for which there is no necessary causal relationship in logic.

Specifically, the method comprises the following steps:

continuously acquiring a food material detection signal;

when the food material detection signal is that food materials are placed, a scene after the food materials are placed is shown in fig. 2, and after the food materials are detected to be placed, the current temperature of the food materials is detected. Generally, the food material is taken into the refrigerator from the room temperature, the temperature of the food material is very high relative to the temperature in the refrigerator, and at this time, the refrigerator is refrigerated at a relatively high air speed, so that the rapid cooling just started does not affect the freezing time in the ice crystal zone because the temperature of the food material just started is relatively high, but sometimes, for example, in winter, or the cool fresh food material purchased by a user, the temperature of the food material is relatively low, at this time, the duty ratio of the fan 8 can be reduced, for example, the initial duty ratio is set by the corresponding relation of the following table 1, and the higher the duty ratio is, the higher the rotating speed of the fan 8 is. Wherein X is the temperature difference between the current temperature of the food material and the maximum value of the target temperature interval, and the maximum value of the target temperature interval may be the minimum value of the second temperature interval, for example, the current temperature of the food material is 10 degrees celsius, the minimum value of the second temperature interval is 0 degree celsius, at this time, x=10, and the duty ratio is 100%; when the current temperature of the food material is 2.5 ℃, the minimum value of the second temperature interval is-1 ℃, and at the moment, X=3.5, the duty ratio is 80%.

Temperature difference X between current temperature and maximum value of target temperature interval of food	Duty cycle

4＞X≥3	80％
		3＞X≥2	50％
2＞X≥1	25％
		0＜1	0

TABLE 1

And then, presetting a time period t at intervals, acquiring precooling temperature information of food materials, wherein the time period t is a detection and adjustment period, the period can be 2 minutes, namely, the target rotating speed of the fan 8 can be adjusted every 2 minutes according to the temperature difference and the temperature difference change rate, and the period can also be adjusted according to a specific refrigerator.

Outputting first rotation speed information to the fan 8 when the pre-cooling temperature information is in a first temperature interval;

outputting second rotation speed information to the fan 8 when the precooling temperature information is in a second temperature interval, wherein the temperature in the second temperature interval is lower than that in the first temperature interval, and the rotation speed of the fan corresponding to the second rotation speed information is lower than that of the fan corresponding to the first rotation speed information;

when the pre-cooling temperature information is in a target temperature interval, outputting preset rotating speed information to the fan 8; the temperature of the target temperature interval is lower than that of the second temperature interval, and the fan rotating speed corresponding to the preset rotating speed information is higher than that of the fan corresponding to the second rotating speed information.

When the food material temperature is within the first temperature interval, the first temperature interval may be a higher temperature relative to the freezer, such as 10 ℃,20 ℃, etc.; in the target temperature interval, the food material will pass through the ice crystal zone with continued freezing, and in the second temperature interval, the temperature of the food material is relatively close to the ice crystal zone but not reached, and is not already in a higher temperature state.

The steps show that when the temperature of the food material is higher, the rotating speed of the fan is high, the refrigerating speed is high, when the temperature of the food material approaches to the temperature of the ice crystal zone, the refrigerating speed is reduced, and particularly the temperature reduction speed of the outer surface of the food material is reduced, and the temperature reduction in the food material is waited.

After the temperature of the interior of the food material is reduced to the minimum value of the second temperature interval, the rotating speed of the fan starts to be increased, so that the interior and the exterior of the food material pass through the ice crystal belt together at full speed, and the speed of passing through the ice crystal belt is improved.

The cooling process is shown in fig. 3, and the change of the duty ratio is controlled along with the change of the temperature.

According to the freezing control method, the time length of the food passing through the ice crystal belt can be effectively reduced, the food is refrigerated at a low speed before entering the ice crystal belt, the cold quantity received by the outer surface of the food is small, when the food is cooled to a proper temperature from inside to outside, the temperature difference between the inside and the outside of the food is small, the food is quickly cooled through the ice crystal belt in an accelerating way, the problem that the time length of the whole ice crystal belt is too long due to the fact that the temperature difference between the inside and the outside of the food is large is avoided, and due to the fact that the time length of the food passing through the ice crystal belt is short, nutrition is locked, the taste of the food is improved, and the use experience of a user is greatly improved.

Further, the duty ratio of the preset rotation speed information corresponding to the rotation speed control signal of the fan is 100%, that is, when the pre-cooling operation is ready to be completed, the rotation speed of the fan 8 is gradually reduced to a temperature difference between the inside and the outside of the food material, and full-speed refrigeration is started again, so that the food material rapidly passes through the ice crystal zone, and the problems that the outside of the food material is very cold, the inside of the food material is not cold, and the temperature difference between the inside and the outside is large are caused.

Further, the step of outputting the preset rotation speed information to the fan when the pre-cooling temperature information is within the target temperature interval further includes:

the maximum value of the temperature in the third temperature interval is the target freezing temperature or the current compartment temperature, and when the freezing temperature information of the food material is equal to the current compartment temperature, the freezing of the food material can be considered to be in a relatively balanced state, namely, the temperature inside and outside the food material is consistent with the temperature of the compartment;

the rotation speed control signal corresponding to the third rotation speed information is a normal refrigeration duty cycle, or the duty cycle corresponding to the preset rotation speed information is changed into the normal refrigeration duty cycle after being maintained for a preset period of time, and the food material is placed on the food material temperature detection module 4 and is not necessarily completely equal to the temperature of the most center of the food material, so that the duty cycle of 100% of a period of time is continuously maintained, and thorough cooling of the food material is facilitated.

Further, the step of outputting the second rotation speed information to the fan 8 when the pre-cooling temperature information is within the second temperature interval further includes:

when the pre-cooling temperature information is in the second temperature interval, if the pre-cooling temperature difference is smaller and/or the change rate of the pre-cooling temperature difference is larger, the fan rotation speed corresponding to the second rotation speed information output to the fan 8 is smaller. The smaller the pre-cooling temperature difference is, the closer the current temperature is to the target temperature interval, the rotation speed of the fan 8 needs to be reduced at the moment, the larger the change rate of the pre-cooling temperature difference is, the faster the temperature is reduced at the moment, the rotation speed of the fan 8 needs to be reduced at the moment, and the situation that the inside of the food is not completely cooled and the outside of the food passes through the ice crystal zone is prevented.

Conversely, when the pre-cooling temperature difference is larger, the temperature difference is far away from the target temperature interval, the rapid refrigeration can be performed firstly, and the operation is performed with a larger duty ratio; when the pre-cooling temperature difference is smaller, the refrigeration load is large, the temperature is difficult to drop, the refrigerating speed can be higher, the refrigerating machine can operate at a larger duty ratio, and the refrigerating speed is prevented from being too slow.

How to comprehensively adjust the rotation speed of the fan 8 according to the pre-cooling temperature difference and the change rate of the pre-cooling temperature difference is judged by the following method and illustrated.

Matching the current pre-cooling temperature difference X (t) to a first set of coefficients, the first set of coefficients comprising (x1=a1, x2=a2 … … xi=ai … … xn=an);

matching the current pre-cooling temperature difference change rate Y (t) to a second coefficient set comprising (y1=b1, y2=b2 … … yi=bi … … yn=bn);

obtaining a first set of weighting coefficients matching the first set of coefficients, the first set of weighting coefficients comprising (z1=c1, z2=c2 … … zi=ci … … zn=cn), and a second set of weighting coefficients matching the second set of coefficients, the second set of weighting coefficients comprising (q1=d1, q2=d2 … … qi=di … … qn=dn);

calculating a fan 8 adjustment parameter d based on the first coefficient set, the second coefficient set, the first weighting coefficient set, and the second weighting coefficient set, wherein,

and calculating the second rotation speed information F (t) according to the fan rotation speed F (t-1) at the previous time, the fan 8 adjusting parameter d and the preset weight q, wherein F (t) =F (t-1) +d.q, the fan 8 adjusting parameter d can be positive or negative, the duty ratio is increased when positive, and the duty ratio is reduced when negative.

When the duty cycle corresponding to the fan rotation speed F (t-1) has been 100%, the duty cycle is not increased even if d is positive.

Further, the minimum value of the first temperature interval is 4 degrees celsius, the minimum value of the second temperature interval is 0 degrees celsius, and the duty ratio of the first rotational speed information corresponding to the rotational speed control signal of the fan 8 is 100%.

In this embodiment, a first set of coefficients is determined according to table 2, a second set of coefficients is determined according to table 3, a first set of weighting coefficients is determined according to table 4, a second set of weighting coefficients is determined according to table 5,

Table 5 correspondence between the second coefficient set and the second weighting coefficient set

For example, when the temperature is detected every preset period t with the minimum value of the second temperature interval of 0 ℃, the temperature of the food material is found to be changed to 10 ℃, 7 ℃, 5 ℃,2 ℃, 1.3 ℃, 0.8 ℃,

the initial temperature was 10℃and the initial duty cycle was 100% as shown in Table 1.

When changing from 10 ℃ to 7 ℃, since 10 and 7 are both greater than 4, X takes the adjusted value of 4, y=4-4=0, corresponding x1=2, x2=0, x3=0, x4=0, x5=0, y1=2, y2=0, y3=0, y4=0, y5=0,

since F (t) =f (t-1) +d=100++q at this time, the initial duty cycle is already due100%, so that the fan rotation speed is not increased any more at this time, and the duty ratio of 100% is maintained.

Similarly, a 100% duty cycle is maintained from 7 ℃ to 5 ℃.

When the temperature is changed from 5 ℃ to 2 ℃, the adjusted X is changed from 4 to 2, corresponding Y=2-4= -2, when x1=0, x2=0, x3=2, x4=0, x5=0, y1=0, y2=0, y3=2, y4=0, y5=0,

at this time, F (t) =f (t-1) +d=100% -q, and by adjusting the coefficient of q, it has been possible to achieve a decrease in the duty cycle when the temperature falls below 4 ℃.

Similarly, when the temperature is changed from 2 ℃ to 1.3 ℃, the adjusted X is changed from 2 to 1, and the corresponding Y=1-2= -1, wherein X1=0, X2=0, X3=0, X4=2, X5=0, Y1=0, Y2=2, Y3=0, Y4=0, Y5=0,

at this time, F (t) =f (t-1) +d=100% -q-1.25q, compared with the previous time, the fan rotation speed is reduced more, and meanwhile, the duty cycle of the fan 8 is reduced more rapidly, so that the characteristic that the fan rotation speed is reduced more rapidly when the temperature is closer to the target temperature is reflected.

Similarly, when the temperature is changed from 1.3 ℃ to 0.8 ℃, X is changed from 1 to 0.5, corresponding to y= -0.5, x1=0, x2=0, x3=0, x4=1, x5=1, y1=1, y2=1, y3=0, y4=0, y5=0, d= -1.25, that is, on the basis of the last adjustment of the fan rotation speed, the fan rotation speed is further reduced, and the characteristic that the fan rotation speed is reduced to be lower when the temperature is closer to the target temperature interval is realized.
