All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As used in the examples of the present invention and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, and "a" and "an" generally include at least two, but do not exclude at least one, unless the context clearly dictates otherwise.
It should be understood that the term "and/or" as used herein is merely a relationship that describes an associated object, meaning that three relationships may exist, e.g., a and/or B, may represent: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
It is also noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a good or system that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such good or system. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a commodity or system that includes the element.
Example 1:
as shown in fig. 1 and 2, which are schematic structural diagrams of an embodiment of an air-cooled refrigerator, a refrigerator 10 includes a refrigerating chamber 1, a freezing chamber 2, and a compressor 4, wherein the refrigerating chamber 1 is located at an upper portion of the refrigerator, the freezing chamber 2 is located at a lower portion of the refrigerator, a temperature and humidity sensor 3 and a main control panel 5 are further disposed at the upper portion of the refrigerator, and a display screen 6 is disposed on a side of a front face of the refrigerator facing a user.
As shown in fig. 3, the present embodiment provides an embodiment of a control method, which takes an air-cooled refrigerator as an example. The refrigerator comprises a defrosting program, under the defrosting program, the control method of the refrigerator comprises the following steps,
s102, acquiring the environment temperature, the environment humidity, the refrigerator electrifying time and the refrigerator door opening time under a defrosting judgment program;
s104, determining a calculation rule of a duration accumulation constant according to the environment temperature and the environment humidity;
s106, calculating a time length accumulative constant according to the power-on time length of the refrigerator, the door opening time length of the refrigerator and the calculation rule of the time length accumulative constant;
s108: and determining whether to control the refrigerator to enter a defrosting program according to the time length accumulation constant.
In the control method of the embodiment, the environment temperature and humidity of the refrigerator are acquired, so that a method of combining the environment temperature and the indoor temperature is considered, the reliability of a defrosting procedure is mainly ensured, the problems of excessive frosting and insufficient frosting of the air-cooled frostless refrigerator are solved by adopting the entering defrosting procedure of the environment temperature and humidity, the entering condition of defrosting is optimized on the basis of not increasing the existing cost of the refrigerator, the power consumption of the refrigerator can be reduced, the energy efficiency of the refrigerator is improved, the temperature stability of the indoor temperature of the refrigerator is improved, and the refrigeration reliability can be improved.
It can be understood that in the case of over-frosting and under-frosting, if the way of conventional defrosting is also adopted, it may result in over-frosting, incomplete defrosting, or under-frosting, the defrosting operation wastes energy. Therefore, the environmental humidity and the environmental temperature, as well as the power-on time and the door opening time of the refrigerator are comprehensively considered to ensure the defrosting accuracy, reduce the energy consumption of the refrigerator and ensure the refrigeration reliability.
It can be understood that the environmental temperature and the environmental humidity described in the present invention refer to the environmental temperature and the environmental humidity of the environment where the refrigerator is located, for example, when the refrigerator is placed indoors (in this embodiment), the environmental temperature and the environmental humidity are the environmental temperature and the environmental humidity of the room where the refrigerator is located (in the drawings, referred to as "indoor environmental temperature" and "indoor environmental humidity" for short).
In addition, the power-on time length of the refrigerator is the total power-on operation time length from the time when the refrigerator operates again to the current detection time after the last defrosting is finished, and for the refrigerator adopting the intermittent operation, the power-on time length comprises the time when the compressor operates and the time when the compressor does not operate.
Example 2:
in order to more accurately control the defrosting operation based on different ambient temperatures and different ambient humidity, the calculation rule of the duration accumulation constant is further optimized based on embodiment 1.
Preferably, a plurality of calculation rules of the duration cumulative constants are provided, and each calculation rule of the duration cumulative constant has a corresponding preset temperature interval range and a corresponding preset humidity range. Therefore, the calculation rule of the duration accumulation constant can be determined by judging the preset temperature interval range to which the current environment temperature belongs and the preset humidity range to which the current environment humidity belongs, so that the corresponding duration accumulation constant calculation rule can be selected according to the specific current environment temperature and the specific current environment humidity, then the duration accumulation constant can be calculated by corresponding refrigerator electrifying duration, refrigerator door opening duration, corresponding correction coefficients and time constants, and finally whether defrosting operation is carried out or not is judged according to the obtained time constant to ensure the defrosting control accuracy.
Specifically, the calculation rule of the duration cumulative constant is to calculate the duration cumulative constant according to the formula Y ═ Ka × t3+ Kb × t1+ Kc; wherein: t3 is the refrigerator power-on time length; t1 is the door opening time of the refrigerator; y duration accumulation constant; ka is a correction coefficient of the power-on time t3 of the refrigerator and is related to the type of the calculation rule; kb is a correction coefficient of the refrigerator door opening time t1 and is related to the type of the calculation rule; kc is a time constant associated with the calculation rule type of the duration accumulation constant.
For example, when we design four types of calculation rules:
in the first calculation rule: k4, Kb K5, Kc K6, and Y K4 t 3 +K5*t 1 + K6; wherein the value range of K4 is 1-1.5, the value range of K5 is 5-7, and the value range of K6 is 10-12 min;
in the second calculation rule: k10, Kb K11, Kc K12, and Y K10 t 3 +K11*t 1 + K12; wherein the value range of K10 is 1.1-1.3, the value range of K11 is 6-9, and the value range of K12 is 9-13 min;
in the third calculation rule: k1, Kb K2, Kc K3; k1 t 3 +K2*t 1 + K3; wherein the value range of K1 is 0.9-1.1, the value range of K2 is 3-5, and the value range of K3 is 7-9 min;
in the fourth calculation rule: k7, Kb K8, Kc K9; k7 t 3 +K8*t 1 + K9; wherein the value range of K7 is 1.3-1.7, the value range of K8 is 7-9, and the value range of K9 is 12-14 min.
K4, K5 and K6 are obtained by analyzing defrosting tests, parameters are used for data correction, conditions of a system defrosting program are optimized in an accumulation mode, a cutting mode is avoided, targeted defrosting can be performed by defrosting operation through the control method, the defrosting effect is guaranteed, and the energy efficiency of the refrigerator is improved.
That is to say, the first to fourth calculation rules described in this embodiment are obtained by multiplying the power-on time length of the refrigerator and the door-opening time length of the refrigerator by the corresponding coefficients and adding the corresponding time length constants, that is, the first to fourth calculation rules are different, and it is determined by selecting different calculation rules according to different ambient temperatures and humidities to obtain different time length integration constants, so as to perform a targeted determination on whether to perform a defrosting operation for different ambient temperatures and different ambient humidities, which is also obviously different from a conventional defrosting operation.
Example 3:
in the following, we take four types of calculation rules as examples to give a specific implementation example of the control method:
as shown in fig. 4 to 5, the step S104 "determining the calculation rule of the time period integration constant according to the ambient temperature and the ambient humidity" according to embodiment 1 may further include the control steps of:
s202: judging whether the ambient temperature meets a first preset condition or not;
if yes, go to step 204;
s204: judging whether the environmental humidity meets a second preset condition or not;
if yes, go to step 206;
if not, go to step 306;
s206: determining a calculation rule of the duration accumulation constant as a first calculation rule;
s306: and determining the calculation rule of the duration accumulation constant as a third calculation rule.
When determining a calculation rule of the accumulated time length according to the ambient temperature and the ambient humidity, determining whether the ambient temperature meets a first preset condition, specifically, determining whether the ambient temperature meets the first preset condition includes determining whether the ambient temperature is greater than or equal to a temperature set value (i.e., a first preset temperature threshold), and if the ambient temperature is greater than or equal to the first preset temperature threshold, determining that the ambient temperature meets the first preset condition.
When the environment temperature is judged to be greater than or equal to the first preset temperature threshold value, whether the environment humidity meets a second preset condition is continuously judged, namely whether the environment humidity is greater than or equal to the first preset humidity threshold value is judged, and if the environment humidity is greater than or equal to the first preset humidity threshold value, the environment humidity is judged to meet the second preset condition. And when the ambient humidity meets a second preset temperature threshold, calculating a duration accumulative constant by adopting a first calculation rule.
In fig. 4 and 5, for the sake of complete representation of the judgment flow, steps 202 and 204 in fig. 4 are substantially the same as steps 302 and 304 in fig. 5, and for the sake of more clear description of the logical judgment relationship between the steps, since they are shown in different figures, different numbers are used, but the judgment steps are substantially the same.
Example 4:
further, embodiment 4 provides an embodiment further including the following control step on the basis of embodiment 3, when the judgment result of step S202 in embodiment 3 is that the ambient temperature does not meet the first preset condition.
S410: judging whether the environmental humidity meets a third preset condition or not; if yes, go to step 412, otherwise go to step 414;
s412: determining a calculation rule of the duration accumulation constant as a second calculation rule;
s414: and determining the calculation rule of the duration accumulation constant as a fourth calculation rule.
Specifically, on the premise that whether the ambient temperature meets the first preset condition or not, whether the ambient humidity meets the second preset condition and the third preset condition or not is further judged in combination with the ambient humidity, and then the calculation rules of the duration cumulative constant are determined, wherein the calculation rules include a first calculation rule, a second calculation rule, a third calculation rule and a fourth calculation rule, so that the targeted defrosting operation is performed under different ambient temperature and ambient humidity conditions, and the defrosting accuracy is guaranteed.
In fig. 6, for completely showing the judgment flow, 202 and 204 in fig. 4, 302 and 304 in fig. 5, and 402 and 404 in fig. 6 are substantially the same steps, and for more clearly showing the logical judgment relationship between the steps, different numbers are used because they are shown in different figures, but the judgment steps are substantially the same.
Example 5:
on the basis of the foregoing embodiment, as shown in fig. 7, after determining the first, second, third, and fourth time duration cumulative constant rules and the corresponding time duration cumulative constants according to the foregoing embodiment, the present embodiment further includes the following steps:
s502: judging whether the duration cumulative constant meets a fourth preset condition or not; if yes, go to step 504;
s504: and controlling the refrigerator to enter a defrosting program.
On the premise of the calculation rule of the duration cumulative constant introduced in embodiment 4, the duration cumulative constant is obtained by calculation, and whether the duration cumulative constant meets a fourth preset condition is calculated and judged, and if the duration cumulative constant is greater than the fourth preset condition, the refrigerator is controlled to enter a defrosting procedure.
Preferably, the determining whether the duration cumulative constant meets a fourth preset condition includes determining whether the duration cumulative constant is greater than or equal to a preset duration threshold, and if the ambient temperature is greater than or equal to the preset duration threshold, determining that the duration cumulative constant meets the fourth preset condition.
It is worth noting that the ambient temperature and the ambient humidity can be obtained through a separate temperature sensor and a separate humidity sensor, and can also be obtained through a temperature and humidity sensor integrating the temperature and the humidity into a whole.
Further preferably, the control method further comprises timing the power-on time of the refrigerator when the refrigerator operates again after the last defrosting is finished; and when the power-on time of the refrigerator reaches a set time, operating the defrosting judgment program. The defrosting judgment program is considered to be operated after the refrigerator is operated for a period of time, the aim is to save energy, the refrigerator is stably operated immediately after being powered on, and frost layers are gradually accumulated, so that the time is not counted.
Further preferably, the determining whether the ambient temperature meets a first preset condition is determining whether the ambient temperature is greater than or equal to a preset temperature, and if so, determining that the ambient temperature meets the first preset condition;
further preferably, the judgment of whether the environmental humidity meets a second preset condition is to judge whether the environmental humidity is greater than or equal to the first humidity threshold, and if yes, the environmental humidity is considered to meet the second preset condition; and judging whether the environment humidity meets a third preset condition, namely judging whether the environment humidity is greater than or equal to the second humidity threshold, and if so, determining that the environment humidity meets the third preset condition.
Further preferably, the preset temperature ranges from 18 ℃ to 20 ℃, and the preferred preset temperature is 19 ℃.

Specifically, by the above judgment conditions, the judgment of the defrosting program can be judged in combination with different environmental temperatures and different environmental humidities, and the defrosting accuracy under the conditions of different environmental humidities and different environmental temperatures can be ensured.
Further preferably, the door opening time period includes the sum of the door opening time period of the freezing door of the refrigerator and the door opening time period of the refrigerating door. That is to say, the door opening duration in this embodiment comprehensively considers the door opening durations of the two chambers to ensure the reliability of defrosting judgment. Preferably, the door opening time can be considered independently of the door opening time of the refrigeration door.

If yes, entering the next judgment condition, and continuously judging whether H1 is more than or equal to b; (a is a temperature setting parameter with unit as C, the value range can be set to 18-20 ℃, the preferred value is 19 ℃, b is a humidity percentage setting parameter with unit as C, the value range can be set to 65-80%, when the ambient temperature is at a lower temperature, the temperature is 19 ℃, the corresponding compressor runs at a low rotating speed, the frost is slow, the time interval between two times of frost melting is long, the ambient temperature can be optimized, the effect of further optimizing the frost melting is achieved, the energy efficiency is improved, and the reliability is improved.
