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. The refrigerator generates cold energy by the operation of the compressor. Every section of the refrigerator needs to be defrosted automatically (as shown in the process of fig. 1). Before defrosting, the refrigerator performs normal compressor operation, namely when a certain chamber of the refrigerator reaches the starting temperature, the compressor is started to refrigerate the chamber, and when the temperature of the chamber is reduced to the stopping temperature, the compressor is stopped to operate until the temperature of the chamber is increased to the starting temperature again. In the defrosting operation stage, in order to prevent the temperature of the compartment from being too high after defrosting, the compartment is pre-cooled. And then, the defrosting heater is operated, and the temperature of the refrigerator compartment is greatly increased after defrosting is finished due to the function of the defrosting heater. Therefore, in the recovery period after the defrosting is finished, the refrigerator needs to be warmed up rapidly, so that the refrigerator runs at a high speed and suddenly generates increased noise. Although this stage is an inevitable requirement for defrosting, and the refrigerator has no quality problem in practice, consumers cannot understand the sudden change of the state of the refrigerator, and thus complaints and returns are made.
To this end, as shown in fig. 2, the present application provides an operation control method of a refrigerator.
Step 201: the refrigerator executes the defrosting instruction.
Step 202: and after the defrosting instruction is executed, the refrigerator controls a compressor of the refrigerator to operate according to a first mode so as to convey cold energy to each chamber of the refrigerator.
Step 203: and when the temperature of each chamber of the refrigerator meets a set condition, controlling the compressor of the refrigerator to operate according to the second mode.
The setting condition may be that the temperature of each compartment is reduced to a shutdown temperature, and the specific rule of the setting condition is not limited herein.
In step 201, the period of time during which the refrigerator executes the defrosting instruction is the time period during which the refrigerator executes the defrosting operation.
In step 202, the temperature difference between before and after the refrigerator executes the defrosting instruction is the difference between the temperature at the starting time of executing the defrosting instruction and the temperature at the ending time of executing the defrosting instruction.
In step 202, at the same sensing temperature of the refrigerator, the average rotating speed of the compressor when operating according to the first mode is greater than the average rotating speed of the compressor when operating according to the second mode, and the rotating speed at any moment is less than the preset maximum openable rotating speed of the compressor; the second mode is an operation mode before the defrosting instruction is executed by the refrigerator. Wherein sensing the temperature comprises at least one of: temperature of a freeze evaporator of a refrigerator; ambient temperature; the compartment temperatures of the refrigerator.
It should be noted that the first mode or the second mode can set the rotation speed of the compressor according to different sensed temperatures. The speed of the compressor in the first mode or the second mode may be constant or may be variable within a certain speed range at the same sensing temperature. Taking the case that the rotation speed of the compressor is not changed under the same temperature as the first sensing temperature as an example, as shown in table 1, the first mode and the second mode are operating gears under different sensing temperatures, wherein each operating gear corresponds to a fixed rotation speed of the compressor, the higher the gear is, the higher the rotation speed is, and for example, the rotation speed of the 2 gear is higher than that of the 1 gear.
TABLE 1
Thus, in an alternative embodiment of step 202, the first mode corresponds to a first operating range; the first operation gear is a gear when the compressor operates according to a first fixed rotating speed; the second mode corresponds to a second operating gear; the second operation gear is a gear when the compressor operates according to a second fixed rotating speed; the first fixed rotational speed is greater than the second fixed rotational speed.
According to the hearing characteristics of the human ear, when the noise variation value is less than a certain value (e.g., 3dB), the user is less sensitive to the noise. When the rotating speed is not changed or the noise change value is smaller than a certain value, the user feels the noise less strongly. Therefore, when the compressor is selected to run after precooling and defrosting are finished, the running speed of the compressor of the refrigerator can be increased to a certain degree (such as 1 gear or 2 gears), and the increase limit value is that the noise value is increased and cannot exceed the preset value (such as 3 dB).
Therefore, in an alternative embodiment of steps 201 to 203, the following settings may be performed:
and the difference value of the average rotating speed of the compressor when the compressor operates according to the first mode and the average rotating speed of the compressor when the compressor operates according to the second mode is less than or equal to a preset rotating speed threshold value.
In the above manner, the rotation speed in the first mode operation and the average rotation speed in the second mode operation are limited within the preset rotation speed threshold range, so that the noise jump is not obvious due to too large difference.
On the other hand, in order to prevent the temperature rise value of the indoor temperature of the refrigerator compartment from being too large after the defrosting of the refrigerator is finished (the temperature rise value refers to the temperature difference between the temperature at any time after the defrosting and the defrosting command execution starting time), the industry standard specifies that the temperature rise value of the refrigerator compartment temperature must not exceed a set temperature (for example, 3 ℃).
Therefore, in order to ensure that the temperature rise value of the compartment of the refrigerator reaches the industry standard, in an alternative implementation manner of step 202, the compressor of the refrigerator may be controlled to operate according to the first mode so as to deliver the cooling capacity to each compartment of the refrigerator, specifically:
step (1): and the refrigerator determines a target chamber according to the temperature difference of each chamber.
Step (2): and the refrigerator controls a compressor of the refrigerator to operate according to the first mode to convey cold energy to the target compartment.
And (3): and the refrigerator control returns to the step of determining the target compartment according to the temperature difference value of each compartment when the temperature difference value of the target compartment is determined to be not less than the preset cooling threshold value of the target compartment until the temperature of each compartment meets the set condition.
The temperature difference value of each chamber is determined according to the temperature of each chamber at the starting time of the defrosting instruction executed by the refrigerator and the temperature at the ending time of the defrosting instruction executed by the refrigerator or the temperature of the refrigerator after cold energy is delivered. The temperature before and after the defrosting instruction is executed means that the defrosting instruction is executed.
The determination method may specifically be: when the step (1) is executed for the first time (i.e. not executed from the step (3) back), the temperature difference value of each chamber is the temperature difference value of each chamber at the starting moment of executing the defrosting command of the refrigerator and the ending moment of executing the defrosting command; and (2) when the step (1) is not executed for the first time, the temperature difference of each chamber is the temperature of each chamber at the starting moment of the defrosting instruction executed by the refrigerator and the temperature difference of the refrigerator after cold energy is conveyed.
The step (1) may specifically be: the refrigerator determines N compartments with the largest temperature difference as the target compartments; n is a positive integer. For example, the target compartment is the compartment of the refrigerator having the highest temperature difference.
It should be noted that, in step (3), the preset temperature reduction threshold of the target compartment is determined at least according to the temperature return rate of the target compartment and the temperature reduction rate of the target compartment when the compressor operates according to the first mode.
For example, the target compartment has a temperature return rate of V1, and the compressor operates in the first mode with a temperature decrease rate of V2(V2 is greater than V1); in order to ensure that the refrigerator can achieve a better refrigeration effect (i.e. the temperature drop is greater than a certain preset cooling threshold value L) within a set time period (e.g. t), L needs to satisfy L < (V2-V1) > t.
Next, as shown in fig. 3, the execution of steps (1) to (3) will be described in detail with a specific embodiment.
For example, a refrigerator has 3 compartments: compartment 1, compartment 2 and compartment 3. The main control board of the refrigerator records temperature values of the compartments 1, 2 and 3 before and after defrosting, and the temperature difference (temperature rise value) delta t of each compartment can be obtained by making a difference. The temperature and temperature rise values before and after the end of defrosting of the three compartments are shown in the following table 1:
| before defrosting | After defrosting | Temperature rise | |
| Chamber 1 | t1 | t1’ | Δt1 |
| Chamber 2 | t2 | t2’ | Δt2 |
| Compartment 3 | t3 | t3’ | Δt3 |
TABLE 2 Change in degree of room temperature before and after defrosting
And then, taking t as max { Δ t1, Δ t2 and Δ t3}, firstly, conveying cold quantity to the compartment corresponding to t to cool and warm the compartment, judging the temperature difference again when the temperature is lowered by a preset temperature threshold (0.5 ℃), and continuing cooling and warming the compartment with the temperature difference until the temperatures of all compartments are lowered to the shutdown temperature. The control flow is shown in fig. 3.
In the method of step 201 to step 203, after the defrosting instruction is executed, the refrigerator firstly controls the compressor of the refrigerator to operate according to a first mode so as to deliver cold energy to each compartment of the refrigerator, and because the average rotating speed of the compressor operating according to the first mode is greater than the average rotating speed of the compressor operating according to a second mode at the same sensing temperature of the refrigerator, and the second mode is the operating mode of the refrigerator before the defrosting instruction is executed, the refrigeration of the refrigerator can be effectively accelerated; moreover, the rotating speed of the compressor at any moment when the compressor operates according to the first mode is less than the preset maximum openable rotating speed of the compressor, so that the phenomenon that the rotating speed directly jumps from the average rotating speed when the compressor operates in the first mode to the maximum rotating speed is avoided, a large noise drop is avoided, and when the temperature of each chamber of the refrigerator meets a set condition, the compressor of the refrigerator is controlled to operate according to the second mode, the noise is reduced to the noise of the second mode, and the user experience is improved.
