Detailed Description
In order to better understand the technical solutions, the technical solutions will be described in detail below with reference to the drawings and the specific embodiments of the specification, and it should be understood that the specific features in the embodiments and examples of the present application are detailed descriptions of the technical solutions of the present application, but not limitations of the technical solutions of the present application, and the technical features in the embodiments and examples of the present application may be combined with each other without conflict.
The refrigerator is a refrigerating device used by thousands of households, is also a civil product for keeping food or other articles in a constant low-temperature cold state, can keep constant low temperature and store food so as to keep the food fresh. However, the existing refrigerator generates a large noise in the using process, receives a lot of complaints and returns, and how to avoid the refrigerator from generating the large noise becomes a problem to be solved urgently. In the experimental process, the refrigerator with multiple compressors can cause larger noise when the multiple compressors run together, and particularly, when the rotating speeds of the multiple compressors are the same, the resonance phenomenon can be generated, and larger extra noise is caused. As shown in table 1, the R600a compressor and the R290a compressor are taken as examples, and different noises are generated at different rotation speeds, wherein the unit of the noise is decibel.
TABLE 1
Obviously, the noise can reach 51 db at most after-touch test, and extra noise can be generated under the condition of the same rotating speed, which is not acceptable for users. In order to reduce noise and achieve a cooling effect, as shown in fig. 1, an embodiment of the present application provides an operation mode control method for a refrigerator.
Step 101: and determining that the sensed temperature of the compartments refrigerated by the N compressors of the refrigerator does not meet the set temperature condition. N is a positive integer greater than 1.
Step 102: and controlling the refrigerator to operate for a first preset time according to a first control mode.
The first preset duration comprises a plurality of first time periods; in the first control mode, the number of started compressors is less than N for any one of the plurality of first time periods; each of the N compressors is turned on at least once within the first preset time period.
Wherein the sensed temperature of the compartments cooled by the N compressors may include at least one of: the temperature of the compartment; ambient temperature; the temperature of the refrigeration evaporator of the compartment.
In steps 101 to 102, for example, N is 2, 2 compressors are a first compressor and a second compressor respectively, in step 102, the first preset time period is 100 minutes, including 20 first time periods, the first compressor and the second compressor are alternately operated every 5 minutes, for example, the first compressor is operated within 0 to 5 minutes, and the second compressor is operated within 6 to 10 minutes until the first preset time period is 100 minutes.
If N is 3, the 3 compressors are the first compressor, the second compressor and the third compressor respectively, or after the first compressor and the second compressor operate for a first period of time, the second compressor and the third compressor operate for a first period of time, or only one compressor operates at the same time, for example, after the first compressor operates for a first period of time, the second compressor operates for a first period of time, and then the third compressor operates for a first period of time. The specific setting of the first control mode can be flexibly adjusted according to specific situations, and is not limited herein.
In addition, the rotation speed of each compressor can be fixed or variable, and the specific variation range can refer to the actual noise level requirement, for example, when the required noise is not more than 1200rpm of the first compressor and 2000rpm of the second compressor when 3 compressors are used, the rotation speed of the first compressor can be changed below 1200rpm and the rotation speed of the second compressor can be changed below 2000rpm when the first compressor and the second compressor are simultaneously operated.
In an optional implementation manner after step 102, if there is a compressor in the N compressors whose sensed temperature of the refrigerated compartment does not satisfy the set temperature condition, the refrigerator is controlled to operate in the second control mode for a second preset time period.
The second preset duration comprises a plurality of second time periods; in the second control mode, aiming at any one of the plurality of second time intervals, the number of started compressors is less than N, and each compressor in the N compressors is started at least once within the first preset time length; for any of the N compressors, the average rotational speed of the compressor in the second control mode is greater than the average rotational speed of the compressor in the first control mode.
The rotation speed of the compressor may be variable or fixed. In an alternative embodiment, the first control mode corresponds to a first fixed speed for any of the N compressors; the second control mode corresponds to a second fixed rotation speed; the first fixed rotational speed is less than the second fixed rotational speed.
In the above manner, the compressor has a fixed rotation speed in both the first control mode and the second control mode, and the first fixed rotation speed is smaller than the second fixed rotation speed, and is also switched to the fixed rotation speed during switching, so that the sound stability of the operation of the compressor is ensured.
For example, the first predetermined time period is 100 minutes, and the second predetermined time period is 80 minutes. For the first compressor, the first compressor is operated at the fixed rotation speed of 1200rpm within the first preset time period, after the first preset time period of 100 minutes, the temperature of the compartment refrigerated by the first compressor is still not less than the shutdown temperature of the compartment, and the first compressor is operated at the fixed rotation speed of 1400rpm within 80 minutes of the second preset time period, so that the compartment refrigerated by the first compressor is refrigerated more quickly.
In the method, after the refrigerator is controlled to operate in a first control mode for a first preset time, if the compressors with the sensing temperatures of the refrigerated compartments not meeting the set temperature condition exist in the N compressors, it is indicated that some of the refrigerated compartments of the compressors do not meet the refrigeration requirement, so that the refrigerator is controlled to operate in a second control mode for a second preset time, and the average rotating speed of any compressor in the second control mode is greater than that of the compressor in the first control mode, so that the refrigeration of the refrigerated compartments of each compressor is accelerated.
Obviously, in an alternative embodiment of controlling the refrigerator to operate in the second control mode for a second preset period of time, it may happen that the rotation speed of each of the N compressors is the highest rotation speed at which the compressor can operate. In an optional implementation manner, if the rotation speed of each of the N compressors is the highest rotation speed at which the compressor can operate, the refrigerator is controlled to operate in a third control mode for a third preset time period.
And in the third operation mode, the N compressors are all started, and the rotating speed of each compressor in the N compressors is smaller than the highest rotating speed at which the compressor can operate and is different from the highest rotating speed at which the compressor can operate.
For example, when N is 2, the rotation speed of the first compressor and the second compressor are 4200 rpm. When at the second preset duration, 4200rpm was reached in alternate operation. And controlling the refrigerator to operate according to a third control mode for a third preset time period so as to avoid resonance caused by the same rotating speed of the compressors, wherein the rotating speeds of the compressors are different when the refrigerator operates at the same time. For example, the speed of the first compressor is reduced 1/3 to 2800rpm, and the speed of the second compressor is reduced 1/2 to 2100 rpm.
In the method, if the rotating speed of each compressor in the N compressors is the highest rotating speed at which the compressor can operate, and the refrigerating compartment still cannot meet the refrigerating requirement when the rotating speed of the compressor reaches the highest rotating speed, the refrigerator is controlled to operate according to a third control mode for a third preset time, in the third operation mode, the N compressors are all started, so that each compressor continuously performs refrigerating operation, and the rotating speed of each compressor in the N compressors is smaller than the highest rotating speed at which the compressor can operate and different from each other, so that extra resonance noise generated by the compressors at the same rotating speed is avoided.
In the above embodiments and optional embodiments of step 101 to step 102, N compressors may be dynamically changed, specifically:
when N is larger than 2, for any one of the N compressors, when the sensing temperature of the compartment refrigerated by the compressor meets a set temperature condition, the compressor is removed from the N compressors, and the N-1 compressors after removal are used as the N compressors again; or, if it is determined that the refrigerator determines that the sensed temperature of the compartments cooled by the compressors other than the N compressors does not satisfy the set temperature condition, adding the compressors other than the N compressors to the N compressors, and taking the added N +1 compressors as the N compressors again.
In the mode, when N is larger than 2, the compressors of which the sensing temperature of the refrigerated chamber meets the set temperature condition are rejected, and when the sensing temperature of the refrigerated chamber of the compressor does not meet the set temperature condition, the compressors except the N compressors are added into the N compressors, so that the N compressors can be adjusted according to the sensing temperature of the refrigerated chamber, and the flexibility of refrigeration control is guaranteed.
In the method of steps 101 to 102, in the first control mode, in any one of a plurality of first periods of a first preset duration, the N compressors are not all turned on in the first period, and each compressor of the N compressors is turned on at least once within the first preset duration, so as to ensure that the plurality of compressors alternately operate at the same time, and in the first preset duration, the compressor whose sensed temperature of the refrigerated compartment meets the set temperature condition of the compartment is turned off in time, and thus, noise superposition of the N compressors does not cause large noise.
