The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a refrigerator according to an embodiment of the present invention. The refrigerator 100 provided in the embodiment of the present invention includes:
a cabinet 10 serving as a support structure of the refrigerator and having a plurality of compartments therein;
a refrigeration system 20, which comprises a compressor 21 and a fan 22, wherein the compressor 21 is used for providing power for the refrigeration cycle of the refrigerator, and the fan 22 is used for enabling air to enter the evaporator of the refrigerator for heat exchange and sending the air after heat release to the compartment of the refrigerator;
the controller 30 is configured to acquire a compartment temperature of the compartment, an operation time of the compressor, and a current operation gear of the compressor when the refrigerator first enters the silent mode;
and comparing the compartment temperature with a preset temperature threshold, and adjusting the running state of the compressor and the running state of the fan according to a comparison result, the running time of the compressor and the current running gear.
It should be noted that the refrigerator performs a cooling operation by a cooling system to provide cooling energy to the compartment so as to maintain the compartment in a constant low temperature state. Specifically, the refrigeration system of the refrigerator according to the embodiment of the present invention includes a compressor, a fan, an air duct, a condenser, a dry filter, a capillary tube, a fin evaporator, and the like, and the operation of the refrigeration system includes a compression process, a condensation process, a throttling process, and an evaporation process.
Wherein, the compression process is as follows: the power cord of the refrigerator is plugged, the compressor starts to work under the condition that the box body has a refrigeration requirement, a low-temperature and low-pressure refrigerant is sucked by the compressor, and is compressed into high-temperature and high-pressure superheated gas in the cylinder of the compressor and then discharged into the condenser;
the condensation process is as follows: the high-temperature and high-pressure refrigerant gas is radiated by the condenser, the temperature is continuously reduced, the refrigerant gas is gradually cooled to be normal-temperature and high-pressure saturated vapor and further cooled to be saturated liquid, the temperature is not reduced any more, and the temperature at the moment is called as condensation temperature. The pressure of the refrigerant in the whole condensation process is almost unchanged;
the throttling process is as follows: the condensed refrigerant saturated liquid flows into a capillary tube after being filtered by a drying filter to remove moisture and impurities, throttling and pressure reduction are carried out through the capillary tube, and the refrigerant is changed into normal-temperature low-pressure wet vapor;
the evaporation process is as follows: the subsequent vaporization by heat absorption in the evaporator begins not only to reduce the temperature of the evaporator and its surroundings, but also to turn the refrigerant into a low temperature, low pressure gas. The refrigerant from the evaporator returns to the compressor again, and the above processes are repeated to transfer the heat in the refrigerator to the air outside the refrigerator, thereby achieving the purpose of refrigeration.
Referring to fig. 2 and 3, fig. 2 is a noise test curve of the refrigerator in the embodiment of the present invention when the refrigerator operates at night, and fig. 3 is a noise test curve of the refrigerator in the embodiment of the present invention when the refrigerator operates at day. The sound pressure sensors are arranged at various positions under the use environment of the refrigerator, such as a study room 5m away from the refrigerator, a sofa 1.76m away from the refrigerator, a hand basin 1.36m away from the refrigerator and a main bed closest to the refrigerator, so that the noise generated during the operation of the refrigerator is tested in real time. As can be seen from FIG. 2, the refrigerator can detect obvious refrigerator operation sound when working at night, and meanwhile, frequent start-stop noises are easily felt by a user, so that rest of the user is influenced, and the user experience is reduced. As can be seen from FIG. 3, the working operation stage of the refrigerator is not seen from the noise test curve, and the ambient sound pressure level noise of each room varies from 38 dB to 42dB under the test condition of home windowing. Transient burrs are caused by automobile whistling, elevator action and sound of adjacent desks and chairs. Therefore, the refrigerator is in a working state for a long time, the running noise of the compressor is not easy to be perceived by people in the daytime, but the compressor is frequently started and stopped at night when the refrigerator is quiet, particularly when the refrigerator is close to a bedroom, so that the situation of high-noise running occurs in a time period when a user is sensitive to the noise, the rest of the user is influenced, and the user experience is reduced.
The frequency conversion compressor core is switched into the motion by static (the compressor starts), is switched into the transient that stops (the compressor stops) by the motion, because core rotation inertia's existence, the compressor core is in unbalanced state, and frequency conversion compressor's vibration, noise have obvious fluctuation, and the instantaneous change of refrigerating system load can increase vibration, noise value simultaneously. In order to ensure the reliability of refrigeration, the rotating speed of the existing compressor is over-designed, the variable frequency compressor can be started and stopped frequently, the refrigeration cycle is short, the noise fluctuation is obvious, and the extremely poor user experience is brought to users. Referring to fig. 4, fig. 4 is a noise test curve of the compressor at the start-up stage according to an embodiment of the present invention, and it can be seen from fig. 4 that the instantaneous peak noise at the initial start-up stage of the refrigerator is 8dB greater than the steady operation noise value.
In order to solve the problem that noise fluctuation caused by frequent starting and stopping of a compressor is reduced in a time period when a user is sensitive to noise, the embodiment of the invention provides a refrigerator, which comprises: the refrigerator comprises a refrigerator body, a door body and a door body, wherein the refrigerator body is used as a supporting structure of the refrigerator and is internally provided with a plurality of compartments; the refrigeration system comprises a compressor and a fan, wherein the compressor is used for providing power for the refrigeration cycle of the refrigerator, and the fan is used for enabling air to enter an evaporator of the refrigerator for heat exchange and sending the air after heat release to an indoor space of the refrigerator; the controller is configured to acquire a compartment temperature of a compartment when the refrigerator first enters the silent mode, an operating time of the compressor, and a current operating gear of the compressor; and comparing the compartment temperature with a preset temperature threshold, and adjusting the running state of the compressor and the running state of the fan according to the comparison result, the running time of the compressor and the current running gear.
The embodiment of the invention can better control the noise stability in the noise sensitive time period of a user on the premise of ensuring the basic refrigeration performance, reduce the noise fluctuation caused by frequent starting and stopping of the compressor and avoid influencing the rest of the user.
As one optional embodiment, the adjusting the operation state of the compressor and the operation state of the fan according to the comparison result, the operation time of the compressor and the current operation gear specifically includes:
if the compartment temperature is lower than the preset temperature threshold, judging whether the first running time of the compressor reaches a preset time threshold when the refrigerator reaches a stop point; the preset time threshold is the time when the user is in shallow sleep;
if the first running time reaches the preset time threshold, maintaining a first current running gear by the compressor, when the compartment temperature is detected to reach the shutdown point temperature, controlling the compressor to stop, until the compartment temperature is detected to reach the startup point temperature, controlling the compressor to start, and running at the first current running gear;
if first operating time does not reach preset time threshold value, then reduce the compressor first current operation gear, control the fan is shut down, when detecting the second operating time of compressor reaches when presetting time threshold value, control the compressor is shut down, until detecting the room temperature reaches when the start point temperature, control the compressor starts to with the gear operation after reducing.
It should be noted that, taking the control rule of the variable frequency compressor of a certain type of refrigerator as an example, the start-up point and the shutdown point of the compressor of the refrigerator are determined by detecting the difference between the actual temperature of the compartment and the set temperature. For example, when the refrigeration gear is set to be 5 ℃, the variable-temperature gear is set to be-5 ℃ and the freezing gear is set to be-20 ℃, the temperature of the refrigeration 'starting point' is 6.5 ℃, the temperature of the variable-temperature 'starting point' is-3.5 ℃ and the temperature of the freezing 'starting point' is-18.5 ℃, and when the actual indoor temperature of any compartment meets the temperature of the corresponding 'starting point', the variable-frequency compressor starts to operate; similarly, the temperature of the refrigerating 'stop point' is 2.5 ℃, the temperature of the variable-temperature 'stop point' is-5.5 ℃, the temperature of the freezing 'stop point' is-22.5 ℃, and when the actual temperatures of all the compartments all meet the corresponding 'stop point' temperature, the variable-frequency compressor is stopped. It should be noted that the compartment is powered on (requires cooling) when the sensor detects a temperature above the "power on point" and is powered off below the "power off point". When the power is firstly powered on, if the temperature of the chamber is between the power on and power off points, the power is turned on; and starting up when each stage of the commodity inspection is started, if the compartment temperature is between the startup and shutdown points. During energy-conserving and intelligent mode, all close more than 2 hours back at cold-stored and freezing door, cold-stored switch machine point improves 1 ℃ (quick-cooling mode does not influence) respectively, and freezing switch machine point improves 1 ℃ (quick-freezing mode does not influence) respectively, and it is normal then to resume to open the door. When the compressor is ON, if the freezing does not reach the shutdown point, the compressor is started by freezing. After the freezing defrosting is finished, in the first starting period, the refrigeration is stopped for 15min, then the control is carried out according to the mode that the refrigeration is allowed for 10 min- > the refrigeration is stopped for 30min, and the mode is exited after two hours to recover the normal control. When precooling is carried out before freezing and defrosting, the refrigerating chamber stops refrigerating when reaching a stop point or refrigerating for 10 minutes, and then the temperature-changing chamber refrigerates at the set temperature of less than or equal to minus 2 ℃ and does not refrigerate at the temperature of minus 2 ℃; the freezing chamber is refrigerated. Aiming at multi-system refrigerator control, the temperature control of a starting point and a stopping point is mainly performed on a freezing compartment, so that the condition that a refrigerating chamber is frozen is avoided.
The main control board of the refrigerator acquires a mute mode (the mute mode is a special mode for running the refrigerator, and the control of the mute mode is started by entering and exiting actively or automatically and by related mute control, noise which influences normal activities of a user is avoided when the user is in a time period sensitive to noise, such as leisure time, rest time and the like). Firstly, dividing the frequency conversion compressor into a high rotating speed and a low rotating speed, wherein the working rotating speed range of most of the frequency conversion compressors is 1200-4500 rpm, the rotating speed of less than 3000rpm is defined as the low rotating speed, and the rotating speed of more than or equal to 3000rpm is defined as the high rotating speed. Further, the low rotation speed (rotation speed < 3000rpm) of the frequency conversion compressor is divided into a plurality of gears in the embodiment, and the frequency conversion compressor is operated only in the gear with the low rotation speed in the mute mode. It should be noted that the selection of the relevant gear needs to avoid the resonance band. In this embodiment, effect verification is performed by taking a refrigerator of a certain model as an example, as shown in fig. 5, a frequency sweep curve of the compressor at 1700rpm to 3000rpm is shown, and as can be seen from the frequency sweep curve, the inverter compressor has an obvious resonance phenomenon at 1800 ± 20rpm and 2400 ± 30rpm, the inverter compressor needs to avoid the resonance band when setting an operating gear, and the gear design is shown in table 1.
TABLE 1
| Gear position | Rotational speed | PWM signal (signal received by compressor) |
| First gear | 1200rpm | 40Hz |
| Second gear | 1500rpm | 50Hz |
| Three-gear | 1710rpm | 57Hz |
| Fourth gear (Low ring temperature stable operation gear) | 2010rpm | 67Hz |
| Five-gear (high ring temperature stable operation gear) | 2490rpm | 83Hz |
Silent mode gear design principle:
(1) the gear rotating speed is designed and maintained in a low rotating speed interval of the compressor;
(2) avoiding a resonance band of the compressor matched with the whole machine;
(3) the highest gears of the silent mode are the gears for stable operation in the normal mode, and as in the above example, the fourth gear is the stable operation rotating speed of the compressor at low ring temperature, and the fifth gear is the stable operation rotating speed of the compressor at high ring temperature.
The method comprises the steps that in a mute mode, a default user is started, interaction with a refrigerator is not generated, the user cannot actively open and close a door, namely, the indoor temperature of the refrigerator is relatively stable (heat causing the temperature rise of the refrigerator is completely transferred from the outdoor of the refrigerator), after the refrigerator enters the mute mode for the first time, the environment temperature is monitored through an environment temperature sensing head, and an initial gear used after the frequency conversion compressor enters the mute mode is determined according to different environment temperatures.
For example, please refer to fig. 6, fig. 6 is a control flow chart of the low-loop temperature when the refrigerator enters the mute mode for the first time according to an embodiment of the present invention. The main control board detects a first silent mode entering signal of the refrigerator, starts to execute silent mode control, and obtains the temperature of the compartment, the running time of the compressor and the current running gear of the compressor as three gears. The temperature of the compartment is divided into a low ring temperature (Taa < 35 ℃) and a high ring temperature (Taa > 35 ℃), namely the preset temperature threshold is 35 ℃. The default user is in the rest stage under the silent mode, and the user does not have the operation of opening refrigerator compartment door etc. and refrigerator interaction, and the refrigerator temperature rise is whole to be caused by the heat transfer, and low ambient temperature needs more cold volume to guarantee that indoor temperature is stable more than high ambient temperature promptly.
If the compartment temperature is less than the preset temperature threshold, that is, under the condition of low ring temperature, it is determined whether the first operation time t1 of the compressor reaches the preset time threshold when the refrigerator reaches the stop point. The preset time threshold is a time when the user is in shallow sleep, and is set to 3h in this embodiment. If the first operation time t1 reaches the preset time threshold value of 3h, namely t1 is not less than 3h, the compressor is kept in three-gear operation, when the compartment temperature is detected to reach the stop point temperature, the compressor is controlled to stop, until the compartment temperature is detected to reach the start point temperature, the compressor is controlled to start, the compressor is operated in three gears, a new working period is started, and the mute mode is exited.
If the first operation time t1 does not reach the preset time threshold value of 3h, namely t1 is less than 3h, which indicates that the temperature of the stop point of the compartment in 3h is reached, the operation gear of the compressor is reduced from the third gear to the second gear, the fan is controlled to stop, and the forced convection circulation of the refrigerator is blocked. When the second running time t2 of the compressor is detected to reach the preset time threshold value of 3h, the compressor is controlled to stop, the compressor is controlled to start up until the compartment temperature reaches the starting point temperature, the reduced gear, namely the second gear, is used for running, and a new working period is started until the silent mode exits. The second operation time t2 includes a time t1 when the compressor is operated in third gear and a time when the compressor continues to operate in second gear after the fan stops operating.
In the mute mode, the embodiment of the invention reduces the starting and stopping times of the compressor in the mute mode by controlling the stop of the fan and reducing the rotating speed of the compressor at the same time, and guides the rotating speed control of the compressor in the follow-up mute mode to achieve the aim of reducing noise fluctuation.
As one optional embodiment, the adjusting the operating state of the compressor and the operating state of the fan according to the comparison result, the operating time of the compressor and the current operating gear specifically includes:
if the compartment temperature is not less than the preset temperature threshold, judging whether the first running time of the compressor reaches a preset time threshold when the refrigerator reaches a stop point;
if the first running time reaches the preset time threshold, maintaining a second current running gear by the compressor, when the compartment temperature is detected to reach the shutdown point temperature, controlling the compressor to stop, and when the compartment temperature is detected to reach the startup point temperature, controlling the compressor to start and run at the second current running gear; wherein the second current operating gear is greater than the first current operating gear;
if the first running time does not reach the preset time threshold, the second current running gear of the compressor is reduced, the fan is controlled to stop, whether the temperature of the compartment reaches the starting point temperature or not is detected in real time, and the running state of the compressor and the running state of the fan are adjusted according to the detection result.
For example, please refer to fig. 7, fig. 7 is a flowchart illustrating a control process at a high ambient temperature when the refrigerator enters the mute mode for the first time according to an embodiment of the present invention.
If the compartment temperature is not less than the preset temperature threshold, namely under the condition of high ambient temperature, the compressor operates in fourth gear, and whether the first operation time t1 of the compressor reaches the preset time threshold when the refrigerator reaches the stop point is judged. If the first operation time t1 reaches the preset time threshold value of 3h, namely t1 is not less than 3h, the compressor keeps operating in fourth gear, when the compartment temperature is detected to reach the stop point temperature, the compressor is controlled to stop, until the compartment temperature is detected to reach the start point temperature, the compressor is controlled to start, the compressor operates in fourth gear, a new working cycle is started, and the mute mode is exited.
If the first operation time t1 does not reach the preset time threshold value of 3h, namely t1 is less than 3h, which indicates that the temperature of the stop point of the compartment within 3h is reached, the operation gear of the compressor is reduced from fourth gear to third gear, the fan is controlled to stop, and the forced convection circulation of the refrigerator is blocked. And simultaneously detecting whether the temperature of the compartment reaches the temperature of the starting point in real time, and adjusting the running state of the compressor and the running state of the fan according to the detection result.

For example, if it is detected that the compartment temperature reaches the start-up point temperature, the compressor is controlled to operate in a reduced gear, that is, in a third gear, the fan is controlled to start, and the operation state of the compressor and the operation state of the fan are adjusted according to a third operation time t3 of the compressor. The third operation time t3 includes a time t1 when the compressor is operated in fourth gear and a time when the compressor continues to operate in third gear after the fan stops operating.
If the compartment temperature is detected not to reach the startup point temperature, when the third running time t3 of the compressor is detected to reach the preset time threshold, the compressor is controlled to stop, until the compartment temperature is detected to reach the startup point temperature, the compressor is controlled to start, the reduced gear, namely the third gear is used for running, a new working period is started, and the mute mode is exited.
As one optional embodiment, the adjusting the operation state of the compressor and the operation state of the fan according to the third operation time of the compressor specifically includes:
if the third running time reaches the preset time threshold and the temperature of the compartment reaches the stop point temperature, controlling the compressor to stop and the fan to stop until the temperature of the compartment reaches the start point temperature, controlling the compressor to start and running at a reduced gear;
if the third operation time does not reach the preset time threshold value, and detect the room temperature reaches the stop point temperature, then control the compressor is in order to reduce the gear operation, control the fan and shut down, until the third operation time reaches the preset time threshold value, control the compressor is shut down, detects the room temperature reaches when the start point temperature, control the compressor starts to gear operation after reducing.
For example, if the third operation time t3 reaches the preset time threshold of 3h and it is detected that the compartment temperature reaches the stop point temperature, the compressor and the fan are controlled to stop, and when it is detected that the compartment temperature reaches the start point temperature, the compressor is controlled to start, and a new operation cycle is started with a reduced gear, that is, a third gear, until the silent mode exits.
And if the third running time t3 does not reach the preset time threshold value of 3h and the compartment temperature is detected to reach the shutdown point temperature, controlling the compressor to run in a reduced gear, namely, in a third gear, stopping the fan until the third running time t3 reaches the preset time threshold value of 3h, controlling the compressor to stop, controlling the compressor to start when the compartment temperature is detected to reach the startup point temperature, and starting a new working period by the reduced gear, namely, in the third gear until the compartment temperature exits the mute mode.
The control flow under the high-ring temperature is that the compressor is not stopped within 3h, the fan is stopped when the stop point is reached, the fan is started when the start point is reached, and the compressor and the fan are stopped when the stop point is reached until the stop point temperature is reached in the time chamber after 3h, so that the influence of the noise fluctuation of the start and stop of the compressor on a user is avoided. After 3h, the user enters the refrigerator compressor in a deep sleep state to operate in the adjusted gear so as to adapt to the cold quantity requirement under the current working condition.

When the refrigerator reaches the stop point and the compressor running time t is less than 3h, namely the temperature of the stop point is reached in the 3h middle chamber, the fan stops working immediately, the compressor is switched to N-1 gear running at the same time, and the continuous running time t of the compressor is recorded 1 (compressor continuous operation time t 1 N-gear running time t and N-1-gear running time of the compressor when the fan stops working) are included, whether the temperature of the compartment reaches the temperature of a starting point or not is detected, and when the temperature of the compressor does not reach the temperature of a stopping point within 3h of continuous running time, t is t 1 Stopping the compressor when the time is more than or equal to 3 hours; when the compressor reaches the starting point temperature within 3h of continuous operation (the heat transfer cold quantity of the evaporator is less than the heat quantity of outdoor heat transfer), the compressor keeps N-1 gear operation and the fan is started, and if the continuous operation time t is in the period 1 When the temperature of the time chamber reaches the temperature of the stop point within more than or equal to 3 hours, the compressor and the fan stop working; if the compartment temperature reaches the stop point temperature again within 3h of continuous operation time, the compressor maintains N-1 gear operation, the fan stops working, and the circulation is carried out until the continuous operation time of the compressor is more than 3h and the compartment temperature reaches the stop pointAnd when the temperature is higher than the preset temperature, the compressor and the fan stop working. And when the room temperature reaches the starting point temperature, starting the compressor, operating the compressor at the N-1 gear, and starting a new working period until the mute mode is exited.
