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 following first introduces terms appearing in the present application.
Dynamic detection mode: an operation mode for checking each component of a refrigerator. The dynamic detection mode is to complete the detection of the refrigerator performance within 20-30min, so that the temperature of the refrigerator is required to be reduced to a specified value in a short time, corresponding electric components such as a compressor, a fan and the like are operated at full load and high frequency, and all electric components are operated at least once during the dynamic detection period in order to ensure the detection of all the electric components. The dynamic detection mode has the following disadvantages: in order to ensure that the refrigerator is cooled in a short time, the compressor and the fan all use higher rotating speed, so that great noise is generated; meanwhile, in order to ensure the normal use of all the electric devices, all the electric devices in the dynamic detection mode are operated once; when the refrigerator is just produced, the refrigerator automatically enters a dynamic detection mode after being powered on by default, and if the dynamic detection mode is carried out at home of a user, complaints of noise and energy consumption are increased to a great extent.
The user operation mode comprises the following steps: besides the dynamic detection mode, the control mode of normal refrigeration of the refrigerator in the normal use process of a user is adopted. Under the condition of a user operation mode, if the control is not carried out, when the refrigerator is electrified for the first time, in order to ensure the quick temperature rise of the refrigerator, all refrigeration parts such as a compressor, a fan and the like run at high frequency under the maximum load; and when the temperature in the box is lower than the set temperature, the compressor is stopped. A plurality of sub-operation modes can be configured in advance in the user operation mode, and the corresponding operation modes can be set according to requirements.
For example, as shown in table 1, the relationship between the operating gear and the PWM frequency in the user operating mode is referred to as a table. It should be noted that, in the example shown in table 1, each gear in the sub-operation mode is a fixed frequency; but in fact, the sub-operation mode can be operated in a certain fluctuation range without setting gears, and the PWM frequency of each gear can also be changed in a certain fluctuation range respectively, and can be flexibly set according to specific requirements.
TABLE 1
| Operating gear | Pulse Width Modulation (PWM) frequency |
| Stop gear | 25Hz |
| Starting gear | 96Hz |
| 1 st gear | 46Hz |
| 2-gear | 67Hz |
| 3 grade | 96Hz |
| 4-gear | 147Hz |
In each operation mode, the operation is carried out according to which frequency and which gear, and the judgment can be carried out according to the sensing temperature of the refrigerator. The sensed temperature of the refrigerator includes at least one of: temperature of a freeze evaporator of a refrigerator; ambient temperature of the refrigerator; the temperature of the compartments of the refrigerator. In addition, other temperatures that the refrigerator can sense may be possible. For example, as shown in table 2, min represents minutes, and in the following operation mode, the control may be performed according to the ambient temperature and the temperature of a compartment to be cooled in the refrigerator, and in each case of the ambient temperature, the operation is performed for a period of time according to the target gear, and then the temperature of the compartment is determined. The method comprises the following specific steps:
TABLE 2
In table 2, Tf is the current temperature of the compartment to be cooled in the refrigerator, and Tft is the set temperature of the compartment.
Low noise mode of operation: and determining that the refrigerator is powered on for the first time. The compressor operates for a period of time at a low-middle-gear rotating speed, and the compressor and the fan are stably switched from the low rotating speed to the high rotating speed to reach the target rotating speed (the target rotating speed is determined by the ring temperature); taking table 3 as an example, the refrigerator is powered on to first determine whether the refrigerator is powered on for the first time, and if the refrigerator is powered on for the first time, the refrigerator enters a low noise operation mode; specifically, the method comprises the following steps: the compressor continuously runs for 60min at the 2 nd gear, then the corresponding running frequency (corresponding to the gear) of the compressor is judged according to the ring temperature, and the low-noise running mode is exited when the power-on time reaches 5 hours or all the compartments simultaneously reach the shutdown temperature.

The low noise operating mode, which may include a first operating mode and a second operating mode, is described in detail below in conjunction with fig. 1. As shown in fig. 1, an embodiment of the present application provides an operation mode control method for a refrigerator, including the following steps:
step 101: after the refrigerator in the user running mode is powered on, the refrigerator is determined to be in a first power-on state.
Step 102: and after the refrigerator operates for a first preset time according to a first operation mode in the user operation modes, switching the operation mode into a second operation mode in the user operation modes.
Obviously, when the refrigerator performs step 101, the operation mode of the refrigerator is already the user operation mode. Before step 101, the following two ways may be adopted, that is, after the refrigerator in the dynamic detection mode is controlled to operate according to the dynamic detection mode, the refrigerator is set to the user operation mode. The method specifically comprises the following steps:
(1) in an optional implementation manner, after the refrigerator in the dynamic detection mode is powered on, the refrigerator runs for a preset number of times according to the dynamic detection mode; and after the refrigerator operates according to the dynamic detection mode for the preset times, setting the operation mode of the refrigerator as the user operation mode.
For example, as shown in fig. 2, after the refrigerator is powered on, the main control board defaults to enter the dynamic detection mode, and can only operate in the dynamic detection mode for 3 times. And automatically exiting the dynamic detection mode after the 3 times of dynamic detection mode operation is finished, and entering a user operation mode. The 3 dynamic detection modes can respectively correspond to five items of safety, high-low pressure leakage detection and performance detection in a factory in sequence. After the dynamic detection mode is carried out for 3 times, the refrigerator is always in the user mode and cannot automatically enter the dynamic detection mode unless manual reset is carried out after the performance of the refrigerator is detected to be qualified. And when the refrigerator performance test is unqualified, the performance repair is carried out, and the refrigerator which is qualified after the repair needs to reset the main control panel of the refrigerator, so that the repaired refrigerator still has a set which runs for 3 times according to a dynamic detection mode. The specific resetting method can be as follows: and the operation is carried out within ten minutes after power-on, the resetting of the main control panel is carried out in a mode of continuously switching on and off the freezing door switch for more than or equal to 5 times or pressing a display screen combination key for a long time in 20S, and the resetting of the main control panel is finished when the freezing illuminating lamp flickers.
In the above manner, after the refrigerator in the dynamic detection mode is powered on and operates for the preset times according to the dynamic detection mode, the operation mode of the refrigerator is set as the user operation mode, so that a method for checking according to times and setting the user operation mode is provided.
(2) In an optional implementation manner, after the refrigerator in the dynamic detection mode is powered on, the refrigerator operates according to the dynamic detection mode, and when the operation duration is not less than a second preset duration, the operation mode of the refrigerator is set as the user operation mode.
For example, as shown in fig. 3, the detailed process may be that the main control board enters the dynamic detection mode by default after the refrigerator is powered on, a time threshold of the dynamic detection mode (a second preset time duration, for example, 518W is 20min) may be set because the power-on time of the five items of security and the high-low voltage detection is short, when the power-on time for the first time exceeds the second preset time duration, the refrigerator exits the dynamic detection mode, each box has only one dynamic detection mode, and after exiting the dynamic detection mode, the refrigerator is always in the user mode unless manual reset is performed. Similarly to the embodiment in (1), similarly, when the refrigerator performance test fails, the performance repair is performed, and the refrigerator after the repair is passed needs to perform a reset operation on the main control board of the refrigerator, so that the repaired refrigerator still has a set of 3 operations in the dynamic detection mode. The specific resetting method can be as follows: and the operation is carried out within ten minutes after power-on, the resetting of the main control panel is carried out in a mode of continuously switching on and off the freezing door switch for more than or equal to 5 times or pressing a display screen combination key for a long time in 20S, and the resetting of the main control panel is finished when the freezing illuminating lamp flickers.
In the above manner, after the refrigerator in the dynamic detection mode is powered on, when the running time according to the dynamic detection mode is not less than a second preset time, the running mode of the refrigerator is set as the user running mode, so that a method for checking according to time and setting the user running mode is provided.
It should be noted that, in an alternative implementation manner of step 101, the refrigerator in the user operation mode may determine that the refrigerator is in the first power-on state according to the following manner:
the refrigerator acquires the sensing temperature of the refrigerator; and the refrigerator determines that the refrigerator is in the first power-on state according to the sensing temperature of the refrigerator.
In the above manner, since the sensed temperature of the refrigerator is reduced after the refrigerator is cooled, it can be determined that the refrigerator is in the first power-on state according to the sensed temperature of the refrigerator.
In an alternative embodiment, the sensed temperature of the refrigerator is the temperature of the freeze evaporator; and if the refrigerator determines that the temperature of the freezing evaporator is greater than or equal to a preset temperature threshold value, determining that the refrigerator is in the first power-on state.
For example, as shown in fig. 4, the temperature of the freezing evaporator is represented by T, the preset temperature threshold is 2 ℃, and when the temperature of the freezing evaporator is 3 ℃, it is determined that the refrigerator is in a first power-on state; and when the temperature of the freezing evaporator is 1 ℃, determining that the refrigerator is in a non-initial power-on state.
In the mode, the freezing evaporator is the most sensitive component after refrigeration of the refrigerator, namely, cold energy is transmitted to the freezing evaporator firstly after the refrigerator is powered on, so that the refrigerator can be more accurately determined to be in the first power-on state according to the sensing temperature of the refrigerator.
In step 102, the average rotating speed of the compressor in the first operation mode is not greater than the average rotating speed of the compressor in the second operation mode, and the difference between the instantaneous rotating speed of the compressor when the refrigerator operates in the first operation mode for the first preset time period and the instantaneous rotating speed of the compressor when the refrigerator starts to operate in the second operation mode is smaller than a preset difference threshold; the second operation mode is a preset operation mode determined according to the sensing temperature of the refrigerator; the different sensing temperatures in the second operation mode correspond to different preset operation modes.
In the method, after the refrigerator in the user operation mode is powered on, the refrigerator does not enter a dynamic detection mode, the first power-on state of the refrigerator in the user operation mode is directly determined, the refrigerator operates for a first preset time according to a first operation mode in the user operation mode, then the operation mode is switched to a second operation mode in the user operation mode, and as the average rotating speed of a compressor in the first operation mode is less than the average rotating speed of the compressor in the second operation mode, and the difference value between the instantaneous rotating speed of the compressor when the refrigerator operates according to the first operation mode for the first preset time and the instantaneous rotating speed of the compressor when the refrigerator starts to operate according to the second operation mode is less than a preset difference threshold value, the noise fluctuation when the refrigerator is switched to the second operation mode after the refrigerator operates according to the first operation mode is ensured to be within a preset control range, the noise of refrigeration in the first preset time length of power-on is lower than the noise of the direct operation of the second operation mode; furthermore, since the refrigeration has been performed for the first preset time period, when the refrigerator switches the operation mode to the second operation mode among the user operation modes, the average rotation speed of the compressor in the second operation mode does not need to reach the rotation speed required for sensing the temperature when the refrigerator is powered on, and the user feels not the noise which is rapidly changed from silence to the second operation mode, but the noise in the first operation mode is changed to the noise in the second operation mode, so that the change of the felt noise is not obvious for the user, and the user experience is improved.
In an alternative embodiment of step 102, the first operating mode includes a plurality of operating ranges; wherein each different operating gear corresponds to a different fixed compressor speed; specifically, step 101 may be performed as follows:
the refrigerator sequentially operates according to the gear sequence within the first preset time; the gear sequence is an arrangement sequence of the rotating speeds of the fixed compressors of the plurality of operating gears from low to high.
For example, taking the relationship between the operating gear and the PWM frequency shown in table 1 as an example, the gear sequence is 1 gear, 2 gears, and 3 gears. The first preset time is divided into three sub-time lengths, the refrigerator in the user mode is controlled to operate for the first sub-time length according to 1 gear, the refrigerator in the user mode is controlled to operate for the second sub-time length according to 2 gears, and the refrigerator in the user mode is controlled to operate for the third sub-time length according to 3 gears.
In the above method, since the first operating mode includes a plurality of operating gears; wherein each different operating gear corresponds to a different fixed compressor speed; when the refrigerator runs sequentially according to the gear sequence within the first preset time, the noise can gradually rise from small to large, and a large noise drop is not caused.
In an alternative embodiment, the first operating mode is a fixed operating range; the refrigerator operates for a first preset time according to a first operation mode in the user operation modes, and the method comprises the following steps: and the refrigerator operates for the first preset time according to the fixed operation gear.
For example, taking the relationship between the operating gear and the PWM frequency shown in table 1 as an example, the refrigerator in the user mode is controlled to operate in 2-gear for a first preset time period according to 2-gear in a fixed operation.
In the method, the first operation mode is a fixed operation gear, and the refrigerator operates according to the fixed operation gear for the first preset time and then operates according to the second operation mode, so that noise is not directly increased from silence to the second operation mode, and a large noise drop is not caused.
As shown in table 4, a noise comparison reference table for the normal operation mode and the low noise operation mode of the compressor is shown, and the corresponding test curve is shown in fig. 5.
