Description

Refrigeration appliance and control method thereof
Technical Field
The invention relates to the technical field of refrigeration appliances, in particular to a household refrigerator and a control method thereof.
Background
In the prior art, in an air-cooled variable frequency refrigerator control system, when a refrigerator storeroom has a refrigeration demand, the refrigeration of the refrigerator is started, and a compressor, a condenser, an evaporator, a fan and the like are all started to work, so that the generated noise is relatively high, the noise sources are relatively more, and superposition effects such as resonance and the like can be formed among the noise sources.
Disclosure of Invention
One of the problems solved by the invention is how to reduce the noise generated by the running of the fan in the refrigeration process.
In order to solve the above problems, the present invention provides a control method of a refrigeration appliance including a fan for sending cold air into different storage compartments, the control method including: when a plurality of the fans are operated at the same time, controlling at least part of the fans to reduce the current operation speed and/or controlling the fans to be at different operation speeds.
When a plurality of fans operate simultaneously to send cold air into different storerooms, the refrigeration device refrigerates, so that the generated noise is relatively high, the current operating speed of the fans can be properly reduced, the noise can be reduced, the operating speed of part of the fans can be reduced, the operating speed of all the fans can be reduced, for example, the speed is reduced to 75% of the current operating speed, and the noise generated by the refrigeration of the refrigeration device is reduced as a whole. Meanwhile, different fans can be controlled to run at different speeds to avoid resonance, and the noise reduction effect is further achieved.
The plurality means two or more.
Further, the fans include a freezing chamber fan for sending cold air into the freezing chamber and a non-freezing chamber fan for sending cold air into the non-freezing chamber, and the control method includes: and when the freezing chamber fan and the non-freezing chamber fan operate simultaneously, controlling the freezing chamber fan to reduce the current operation speed.
By non-freezing chamber is meant that the storage temperature of the non-freezing chamber is not less than zero or the storage temperature range includes a temperature range not less than zero, which may include a cold room, an ice-warm room, a zero-degree fresh room or a temperature-changing room, etc.
Under the condition that the fan reduces the current operation speed to cause insufficient refrigeration, the storage temperature of the freezing chamber is influenced and fluctuates relatively little, and the storage temperature of the non-freezing chamber such as a refrigerating chamber, an ice greenhouse, a zero-degree fresh-keeping chamber or a temperature-changing chamber is influenced and fluctuates relatively much. Therefore, in order to reduce the fan noise as a whole and have less influence on the storage temperature, the current operating speed of the freezer fan may be preferentially reduced.
Further, the control method includes: and when all the non-freezing chamber fans stop operating, controlling the operation speed of the freezing chamber fan before resuming.
Further, the non-freezing chamber fan comprises a refrigerating chamber fan for sending cold air into the refrigerating chamber and a fan for sending cold air into the other non-freezing chamber; the control method comprises the following steps: and when one or more of the refrigerating chamber fan and the fans of other non-freezing chambers are operated at the same time and the freezing chamber fan is not operated, reducing the current operation speed of the refrigerating chamber fan.
The plurality means two or more.
Under the condition that the fan reduces the current operation speed to cause insufficient refrigeration, the storage temperature of the refrigerating chamber is influenced and fluctuates relatively little, and in contrast, the storage temperature of other non-refrigerating chambers such as an ice temperature chamber, a zero-degree fresh-keeping chamber or a temperature-changing chamber is influenced and fluctuates relatively much. Therefore, in order to reduce the fan noise as a whole and have less influence on the storage temperature, the current operation speed of the refrigerating chamber fan can be further reduced preferentially on the premise that the freezing chamber fan stops working.
Further, the control method includes: controlling the operation speed of the refrigerating chamber fan before resuming when all the other non-freezing chamber fans stop operating.
Further, the non-freezing chamber fan comprises a refrigerating chamber fan for sending cold air into the refrigerating chamber and a fan for sending cold air into the other non-freezing chamber; the control method comprises the following steps: when the refrigerating chamber fan and the freezing chamber fan stop working, and two or more than two of the other non-freezing chamber fans operate simultaneously, the current operating speed of the other non-freezing chamber fans which operate simultaneously is not reduced.
When two or more fans of the zero-degree refreshing chamber, the variable-temperature chamber, the ice-temperature chamber and other non-freezing chamber fans operate simultaneously, on the premise that the freezing chamber fan and the refrigerating chamber fan stop working, the operation speed of the fans is reduced, and large fluctuation is easily caused to the storage temperature of the zero-degree refreshing chamber, the variable-temperature chamber and the ice-temperature chamber, so that the current operation speed of the zero-degree refreshing chamber fan, the variable-temperature chamber fan, the ice-temperature chamber fan and other non-freezing chambers can be controlled not to be reduced.
Further, the other non-freezing chamber fans comprise an ice-temperature chamber fan and/or a zero-degree fresh-keeping chamber fan and/or a variable temperature chamber fan.
Further, the control method includes: judging whether the fans are at the same operating speed or not; and if the fans are at the same operating speed, controlling at least one fan to reduce the operating speed to obtain that the fans are at different operating speeds.
The multiple fans are easy to resonate when being at the same running speed, and more noises are generated, so that the different fans are controlled to be at different running speeds under the condition, and the effect of noise reduction can be achieved by avoiding the resonance.
Another aspect of the invention is to propose a refrigeration appliance comprising a control unit which controls the operation of the refrigeration appliance according to the control method of any one of the above.
The subject matter of any independent claim above may be combined with any subject matter or combination of subject matter of any dependent claims as may be permitted under the circumstances of technology to form new claimed subject matter.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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.
Referring to fig. 1, a refrigerator appliance according to an embodiment of the present invention is provided as a home refrigerator having three storage compartments and a side-by-side combination refrigerator independently cooling each. The three independent storage compartments of the refrigerator 100 include a freezing compartment 1, two non-freezing compartments, i.e., a refrigerating compartment 2 located at the upper right of the refrigerator and an ice-warming compartment 3 located at the lower right of the refrigerator, a refrigeration system 10, and a control device (not shown) for controlling the refrigeration system 10. The refrigerating system includes a compressor 4, a condenser 5, a condenser fan 51, an evaporator and a fan, which are respectively independent of the three storage chambers for refrigeration, and the control device includes three temperature sensors (not shown in the figure) which are respectively independent of the storage temperatures of the three storage chambers.
The refrigerating system 10 has three refrigerating cycles for independently refrigerating the above three storage compartments, respectively, each of which is capable of independently controlling the temperature. The refrigeration cycle mainly refers to the circulation flow of the refrigerant in each element of the refrigeration system, for example, starting from the compressor 4, the refrigerant which releases the cold energy and absorbs the heat of the storage chamber is sucked by the compressor 4 in the form of gas, and the vapor which is compressed to high temperature and high pressure enters the condenser 5 through the pipeline, and under the cooling of the condenser fan 51, the refrigerant gives off the heat to the outside air in the condenser 5 and is condensed to the liquid refrigerant of high pressure. Under the split of the first and second split valves 11 and 12, the liquid refrigerant can be controlled to flow to the ice greenhouse evaporator 6, the refrigerating chamber evaporator 7 and the freezing chamber evaporator 8, respectively, to cool the ice greenhouse 3, the refrigerating chamber 2 and the freezing chamber 1, respectively, independently, to achieve the cooling in the three storage chambers. The liquid refrigerant absorbs heat of the storage chamber, is vaporized into vapor refrigerant and is sucked by the compressor 4 again, and the refrigerant enters the next cycle in such a reciprocating manner.
The refrigerant flowing out of the ice-greenhouse evaporator 6 and the refrigerating chamber evaporator 7 generally flows into the compressor 4 after passing through the freezing chamber evaporator 8, because the refrigerant flowing out of the ice-greenhouse evaporator 6 and the refrigerating chamber evaporator 7 also has a part of cold energy and can be used for absorbing heat of the freezing chamber 1. The control device can control the flow direction of the refrigerant by controlling the first flow dividing valve 11 and the second flow dividing valve 12, so that the independent temperature control of the ice greenhouse 3, the refrigerating chamber 2 and the freezing chamber 1 is achieved.
In the present embodiment, the normal set temperature of the freezing compartment 1 is 18 degrees below zero, the normal set temperature of the refrigerating compartment 2 is 2 to 6 degrees, and the set temperature of the ice temperature compartment 3 is 0 to 3 degrees. The three independent storage chambers are all air-cooled, and the air-cooled mode is a refrigeration mode well known to those skilled in the art, and will not be described herein.
In the ice greenhouse 3, an ice greenhouse evaporator 6 is disposed between a rear wall of the ice greenhouse 3 and an evaporator cover (not shown in the drawing) (a space where the evaporator is disposed may be referred to as an evaporator chamber), and an ice greenhouse fan 61 is disposed adjacent to and above the ice greenhouse evaporator 6. The cold air cooled by the ice greenhouse evaporator 6 is blown into the ice greenhouse 3 by the ice greenhouse fan 61 to cool the ice greenhouse 3.
Similarly to the structure of the ice greenhouse 3, in the refrigerating compartment 2, a refrigerating compartment evaporator 7 is also provided between the rear wall of the refrigerating compartment 2 and an evaporator cover (not shown), and a refrigerating compartment fan 71 is provided adjacent to and above the refrigerating compartment evaporator 7 to blow cold air cooled by the refrigerating compartment evaporator 7 into the freezing compartment 1.
Similar to the structure of the ice-temperature chamber 3, in the freezing chamber 1, the freezing chamber evaporator 8 is also disposed between the rear wall of the freezing chamber 3 and an evaporator cover plate (not shown), and the freezing chamber fan 81 is disposed near above the freezing chamber evaporator 8 and blows cold air cooled by the freezing chamber evaporator 8 into the freezing chamber 1.
In the existing air-cooled refrigerator control system, when a certain storeroom is refrigerated according to the control rule of the fan, the corresponding fan is started and stopped at a constant rotating speed when the compressor is started and stopped. For example, when the freezing chamber 1 performs cooling, the freezing chamber fan 81 is started and operated at a constant rotation speed until the cooling is finished and stopped; similarly, when the ice-temperature chamber 3 performs refrigeration, the ice-temperature chamber fan 61 works at another constant rotation speed until the refrigeration is finished and stops working; when the refrigerating chamber 2 is refrigerated, the refrigerating chamber fan 61 is also started and operated at another constant rotational speed until the refrigeration is finished and stopped. When a plurality of storerooms refrigerate simultaneously, a plurality of fans can operate simultaneously, resonance is easy to generate, and the generated noise is relatively large. Therefore, the invention provides an improved refrigerator control method, and particularly improves the control rule of a fan in the refrigeration process, so that the overall performance of a refrigeration system of a refrigerator is further improved.
In one embodiment, an improved control method of a refrigerator is shown in fig. 2, and is described below by specific steps.
In step S101, cooling is started.
In general, a temperature sensor for detecting a storage temperature in the storage compartment is installed in the storage compartment, and the detected storage temperature is fed back to the refrigerator control unit. If the current storage temperature is higher than the set temperature of the storage chamber, the refrigerator control unit starts the refrigeration of the storage chamber accordingly. The refrigerating can be carried out by a single storage chamber or by a plurality of storage chambers simultaneously.
And step S102, starting the compressor and the fan to work.
After the refrigeration is started, the compressor of the refrigerator is started to work, the condenser and the fan of the condenser are also started to work, and the fan of the evaporator which works for the storeroom needing to be refrigerated also works, so that cold air cooled by the evaporator is blown into the storeroom, and the storage temperature of the storeroom is reduced.
And step S103, whether the fans operate simultaneously or not.
Whether the plurality of storerooms are simultaneously refrigerated and whether the fans respectively working for the storerooms simultaneously operate is judged to determine whether the current operation speed of part or all of the fans needs to be reduced, so that noise is reduced.
And when the plurality of fans are judged to be simultaneously operated, the step S104 is carried out, and the current operation speed of part of the fans or all the fans is controlled to be reduced.
When it is determined that the plurality of fans are not operating simultaneously, the process proceeds to step S105.
Step S105, comparing whether the storage temperature is less than or equal to the set temperature.
The storage temperature of each storeroom is obtained through real-time detection, and is compared with the set temperature of the storeroom, and whether refrigeration is stopped or not and the fan is stopped according to the comparison result.
When the storage temperature of a certain storage chamber is detected to be less than or equal to the set temperature of the storage chamber, the storage chamber does not need to be refrigerated at the moment, and a fan blowing cold air into the storage chamber stops working; and when each storage chamber does not need to be refrigerated any more, the step S106 is directly carried out, the compressor and the fan stop working, and the refrigeration is finished.
When the storage temperature of at least one storage chamber is detected to be higher than the set temperature of the storage chamber, the storage chamber needs to be cooled continuously, and the step S103 is carried out for further judgment.
Based on the control method shown in fig. 2, the specific control method can be further divided into two flows:
first, a control flow when the freezing chamber fan is operated.
As shown in fig. 1 and 3 in conjunction, the fans blowing cool air to the respective storage compartments include a freezing compartment fan 81 for sending cool air into the freezing compartment 1 and a non-freezing compartment fan for sending cool air into the non-freezing compartment, the non-freezing compartment fan including a refrigerating compartment fan 71 for sending cool air into the refrigerating compartment 2 and an ice temperature compartment fan 61 for sending cool air into the ice temperature compartment 3.
When it is judged that the freezing chamber fan 81 and the non-freezing chamber fan (including the refrigerating chamber fan 71 and/or the freezing chamber fan 61) are simultaneously operated, the refrigerator preferably controls the freezing chamber fan 81 to reduce the current operation speed, for example, to 75% of the current operation speed, to reduce the noise of the fan operation as a whole.
When all the non-freezing chamber fans stop working, at this time, if the freezing chamber still needs to be refrigerated and the freezing chamber fan 81 still works, the operation speed of the freezing chamber fan 81 can be restored to the previous operation speed until the refrigeration of the freezing chamber 1 is finished.
And secondly, controlling the flow when the freezing fan stops working.
As shown in fig. 1 and 4 in conjunction, in the case where the freezing chamber 1 does not need to be cooled and the freezing chamber fan 81 stops operating, when it is judged that the refrigerating chamber fan 71 and the other non-freezing chamber fan (i.e., the ice greenhouse fan 61 in this embodiment) are simultaneously operated, the refrigerator preferably controls the refrigerating chamber fan 71 to reduce the current operation speed, for example, to 75% of the current operation speed, so as to reduce the noise of the fan operation as a whole.
When all other non-freezing chamber fans stop working, at this time, if the refrigerating chamber 2 still needs to be refrigerated and the refrigerating chamber fan 71 still works, the running speed of the refrigerating chamber fan 71 can be restored to the previous running speed until the refrigeration of the refrigerating chamber 2 is finished.
In another embodiment, the refrigerator may include a refrigerating chamber and more than two non-freezing chambers, for example, two or three of a zero-degree fresh-keeping chamber, a temperature-changing chamber, and an ice-temperature chamber, and the like. The refrigerator control flow of this embodiment adds a special case to the above-described embodiment, that is, when the refrigerating chamber fan and the freezing chamber fan stop operating and two or more of the other non-freezing chamber fans operate simultaneously, the current operating speed of the other non-freezing chamber fans that operate simultaneously is not reduced.
When two or more fans of the zero-degree refreshing chamber, the variable-temperature chamber, the ice-temperature chamber and other non-freezing chamber fans operate simultaneously, on the premise that the freezing chamber fan and the refrigerating chamber fan stop working, the operation speed of the fans is reduced, and large fluctuation is easily caused to the storage temperature of the zero-degree refreshing chamber, the variable-temperature chamber and the ice-temperature chamber, so that the current operation speed of the zero-degree refreshing chamber fan, the variable-temperature chamber fan, the ice-temperature chamber fan and other non-freezing chambers can be controlled not to be reduced.
In order to reduce noise, another control method is provided in another embodiment, namely when a plurality of storage chambers refrigerate at the same time and a plurality of fans which send cold air into corresponding storage chambers operate at the same time, judging whether the plurality of fans are at the same operating speed; if the fans are at the same operating speed, controlling at least one fan to reduce the operating speed to obtain that the fans are at different operating speeds. Because a plurality of fans cause resonance easily when being in the same operating speed, and produce more noises, so control different fans and be in different operating speeds under this condition can avoid resonance and reach the effect of making an uproar.
In any of the above embodiments, the term "zero degree fresh keeping compartment" refers to a storage compartment having a storage temperature range of 0 ℃ to 3 ℃ and a storage compartment having a storage temperature range close thereto. The temperature-changing chamber refers to a storage chamber with a storage temperature range of-6 ℃ to 3 ℃ or-20 ℃ to 8 ℃ and a storage chamber with a storage temperature range close to the storage temperature range. The ice-temperature chamber refers to a storage chamber with a storage temperature ranging from-3 ℃ to 3 ℃.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
