Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the refrigerator control method, the refrigerator and the storage medium according to the present invention will be described in further detail with reference to the accompanying drawings and the detailed description. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration and explanation only and are not intended to limit the scope of the invention.
It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all 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. The technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.
Example 1:
based on the problems, the refrigerator control method is additionally provided with a refrigerator freezing closing function, and a refrigerating and defrosting mode of the refrigerator under the condition of freezing closing is optimized, so that energy consumption of the refrigerator when a user only needs to use a refrigerating function is reduced, the user is helped to save electricity, and the user use experience is improved.
The refrigerator comprises a refrigerating chamber, a freezing chamber, a refrigerating system and a defrosting system, wherein the refrigerating system and the defrosting system are used for refrigerating and defrosting the refrigerating chamber and the freezing chamber, the refrigerating system at least comprises a compressor, a refrigerating fan, a refrigerating air door, an evaporator and the like, and the defrosting system at least comprises a heater. The refrigerator in the embodiment may be a general household refrigerator including a refrigerating chamber and a freezing chamber, and the working states of the refrigerator include a refrigerating state and a defrosting state. That is, the refrigerator control method of the present embodiment is applicable to a refrigerator having a cooling stage and a defrosting stage as long as the refrigerator includes both a refrigerating chamber and a freezing chamber.
As shown in fig. 1, the present embodiment provides a method for controlling a refrigerator, where the refrigerator is provided with a freeze-off selection function, and when the freeze-off function is selected, the operation modes of the refrigerator are as follows:
acquiring set gears of the refrigerating chamber and the temperature corresponding to each set gear;
acquiring the actual temperature of a refrigerating chamber and the actual temperature of a freezing chamber;
and controlling the working states of a compressor and a heater of the refrigerator according to the actual temperature of the refrigerating chamber, the starting point temperature, the stopping point temperature and the actual temperature of the freezing chamber of the set gear to realize refrigeration and defrosting.
In the control method of the refrigerator, the freezing shutdown means that the whole refrigerating system does not need to operate according to the set temperature of the freezing chamber, namely the freezing chamber does not need to be considered, and only needs to operate at the set temperature of the refrigerating chamber. In this case, the freezing chamber is not recommended to be used as the refrigerating chamber because the freezing chamber is not considered at this time, but the freezing chamber is generally designed to be closer to the evaporator in position, that is, the freezing chamber is lower in temperature when the compressor is operated, and is therefore not recommended to be used as the refrigerating chamber (2 ℃ C. to 8 ℃ C.).
The logic of the freezing closing function of the refrigerator and the cooling and defrosting modes under the freezing closing function will be described in detail below with reference to fig. 1 and 2.
First, the temperature and time according to the embodiment will be described as follows:
tc: the actual temperature of the refrigerating chamber is measured by a refrigerating chamber temperature sensor;
ton: the starting point temperature of the gear of the refrigerating chamber is set, Ton = set gear temperature value +2 ℃, and the Ton value can be changed according to actual requirements in the implementation process;
toff: the shutdown point temperature of a set gear of the refrigerating chamber is Toff = set gear temperature value-2 ℃, and the Toff value can be changed according to actual requirements in the implementation process;
td: the actual temperature of the freezing chamber is measured by a freezing chamber temperature sensor;
ths: the actual temperature of the evaporator is measured by an evaporator temperature sensor;
t1: a preset degraded frost temperature, preferably for example between 5 ℃ and 12 ℃, measured by the evaporator sensor;
and (hs): defrosting time;
t 1: the set maximum defrosting time is preferably 20min to 60min, for example.
After the refrigerator is normally powered on, a user can set the temperature of the refrigerating chamber (or the gear of the refrigerating chamber), and then set whether to start the freezing closing function. If the freezing closing function is not started, the user needs to further set the temperature of the freezing chamber, and the refrigerator operates according to normal refrigeration and defrosting logic.
If the opening/closing function is set, the following functions are provided: the refrigerator control method automatically controls the start and stop of a refrigerator compressor through a temperature sensor and an original control circuit in the refrigerator under the condition of freezing closing, so that a refrigerator refrigerating system performs intermittent refrigeration, and the temperature in a refrigerating chamber of the refrigerator is controlled in a low-temperature range required by a user; furthermore, under the frosting condition, the automatic defrosting function is realized.
After the refrigerator is added with the freezing closing function, a user can freely select whether to enter the freezing closing function or not, and by combining keys, for example: the combination of the enter key + compartment selection key/temperature adjustment key, etc. enters the freeze-off function. After entering the freezing closing function, a user can only set the gear of the refrigerating chamber under the function, and after entering the freezing closing function, the refrigerating logic and the defrosting logic of the whole machine are carried out according to the following logic.
The starting and closing of the compressor in the refrigeration stage under the freezing closing function are determined by the actual temperature of the refrigerating chamber. In the step of controlling the working state of the compressor of the refrigerator according to the actual temperature of the refrigerating chamber, the starting point temperature of the set gear, the stopping point temperature of the set gear and the actual temperature of the freezing chamber, the method comprises the following steps:
if the actual temperature of the refrigerating chamber is greater than the starting point temperature of the set gear of the refrigerating chamber, then:
if the actual temperature of the freezing chamber is lower than the stop point temperature of the set gear of the refrigerating chamber, the refrigerating air door is opened and only the refrigerating air door is opened, and the compressor maintains the previous state;
and if the actual temperature of the freezing chamber is greater than the stop point temperature of the set gear of the refrigerating chamber, starting the compressor, the freezing fan and the refrigerating air door to refrigerate the refrigerating chamber.
Wherein, the starting point temperature of the setting gear of the refrigerating chamber is as follows: (the temperature + N) DEG C corresponding to the set gear, and the shutdown point temperature of the set gear of the refrigerating chamber is as follows: (the temperature corresponding to the set gear is-N) DEG C, and N is any number between 1 and 3. The gears of the refrigerating chamber of the refrigerator can comprise 0-7 gears, and the starting point temperature and the stopping point temperature of different gears are different.
During the operation of the refrigerator, the compressor compresses the refrigerant when being started, the gaseous refrigerant is changed into liquid, the refrigerant is liquefied and releases heat due to the change of the state of the refrigerant, and the heat is released through a condenser outside the refrigerator, so that the refrigerant is cooled. After the refrigerant close to normal temperature is sent to the indoor evaporator through the capillary tube, the refrigerant begins to boil due to the relatively low pressure of the evaporator, so that the refrigerant is vaporized, a large amount of heat is absorbed in the vaporization process to cool the evaporator, and the evaporator exchanges heat with the air in the refrigerating chamber and continuously circulates to realize refrigeration.
That is, the refrigerating chamber has a refrigerating request, and if the actual temperature of the freezing chamber is lower than the stop point temperature of the set gear of the refrigerating chamber, only the refrigerating air door is opened to supply cold to the freezing chamber. And if the actual temperature of the freezing chamber is greater than or equal to the stop point temperature of the set gear of the refrigerating chamber, the compressor is started to supply cold for the refrigerating chamber. It should be understood herein that since the freezer compartment is closer to the evaporator after the freezing function is turned off, the temperature of the freezer compartment is also low (about-10 c) when the compressor is operated regardless of the freezer compartment, and therefore the freezer compartment can be cooled first by the freezer compartment when the temperature of the freezer compartment is sensed to meet the demand (the actual temperature of the freezer compartment is less than the stop point temperature of the set gear of the freezer compartment) after the request for cooling of the refrigerator compartment.
For example, the gear of the refrigerating chamber can be selected from 2 ℃ to 8 ℃, and whether the refrigerating chamber needs to be refrigerated is controlled by comparing the actual temperature of the refrigerating chamber with the starting point temperature and the stopping point temperature of the set gear. If the set gear temperature is selected to be 2 ℃, and N =2, the starting point temperature Ton of the set gear of the refrigerating chamber is =4 ℃, the stopping point temperature Toff of the set gear of the refrigerating chamber is =0 ℃, when Tc (actual temperature of the refrigerating chamber) > Ton (starting point temperature of the set gear of the refrigerating chamber is 4 ℃), it is considered that the temperature of the refrigerating chamber is higher, and refrigeration is needed, and at this time, the temperature of the freezing chamber is further determined:
if Td (actual temperature of the freezing chamber) is less than Toff (shutdown point temperature of a set gear of the refrigerating chamber is 0 ℃), the refrigerating capacity of the freezing chamber is considered to be enough, the refrigerating requirement of the refrigerating chamber can be provided by the freezing chamber, only a refrigerating air door is opened, and the compressor is maintained in the previous state;
and if Td (actual temperature of the freezing chamber) > Toff (the shutdown point temperature of the set gear of the refrigerating chamber is 0 ℃), judging that the refrigerating capacity of the freezing chamber is insufficient, and starting the compressor, the freezing fan and the refrigerating air door to refrigerate the refrigerating chamber.
If Tc (actual temperature of the refrigerating chamber) < Toff (shutdown point temperature of a set gear of the refrigerating chamber is 0 ℃), the refrigerating chamber is considered to reach the temperature requirement, and no refrigeration is needed, if the compressor and the freezing fan are not started, the refrigerating air door is closed, and if the compressor, the freezing fan and the refrigerating air door are all started, all the refrigerating air doors are closed;
if Toff (the shutdown point temperature of the set gear of the refrigerating chamber is 0 ℃) is less than or equal to Tc (the actual temperature of the refrigerating chamber) is less than or equal to Ton (the startup point temperature of the set gear of the refrigerating chamber is 4 ℃), the original running state of the loads such as the compressor, the freezing fan, the refrigerating air door and the like is maintained. It should be understood that Toff ≦ Tc ≦ Ton is a maintaining state, and there are two cases when the actual temperature of the refrigerating compartment enters the temperature interval, namely, the temperature is lowered from high temperature to the interval, and the load maintains the cooling action; secondly, the temperature is increased from the shutdown point to the temperature interval, and at the moment, each load maintains the shutdown state, namely, each load is closed.
In the freeze shutdown function of the above example, the compressor speed may be reduced during the refrigeration phase due to the low refrigeration demand in the freeze shutdown function, and the compressor may be operated in a low speed mode, such as at 1320/1620 rpm.
The refrigerator in the prior art has no freezing closing function, and as long as a refrigerating chamber has a refrigerating request, a compressor can be started or maintained in the previous state regardless of the refrigerating request of a freezing chamber; the compressor is stopped only when there is no refrigeration request in the refrigerating chamber and the freezing chamber. Thus, the control is performed at-16 ℃ to-24 ℃ even when the freezing chamber is not in food storage, resulting in long running time of the compressor and long working time of the defrosting heater in the defrosting stage. The embodiment closes the function through increasing freezing, and the compressor operating duration is short under freezing the function of closing, and the rotational speed is little, and the volume of frosting is little, and defrosting heater operating time is short, reaches the purpose of saving the electric quantity.
In the step of controlling the working state of the heater of the refrigerator according to the actual temperature of the refrigerating chamber, the starting point temperature of the set gear, the stopping point temperature of the set gear and the actual temperature of the freezing chamber, the method comprises the following steps: and (3) when the power-on time of the whole refrigerator reaches a preset defrosting interval time, for example, the power-on time is more than 96H, entering a defrosting stage, closing the compressor, the freezing fan and the cold storage air door, and opening the heater for defrosting. The defrosting interval time can be flexibly set according to the actual frosting condition of the whole machine, and is not limited here. Because the frost formation amount under the freezing closing function is small, the working frequency of the defrosting heater can be reduced, and the defrosting heater can work under a low duty ratio.
The defrosting condition of the refrigerator in the prior art is any one of the following conditions: the cumulative power supply electrifying time of the whole refrigerator is not less than 24H; or the accumulated working time of the compressor is more than or equal to 12H; or the accumulated power supply power-on time of the whole machine is more than or equal to 12H and the single running time of the compressor is more than or equal to 4H. In the defrosting condition under the refrigeration closing function, the accumulated power supply power-on time of the whole machine is more than or equal to 96H, so that the work load of the compressor is greatly relieved. Certainly, the defrosting interval time can be changed according to the specific frosting amount of different types, and after the defrosting stage is started, all loads are closed, and the defrosting heater is started. In addition, the defrosting logic in the prior art includes stages of forced cooling, return air defrosting, heater operation, water dropping, pre-cooling, etc., whereas the defrosting logic in the embodiment includes and only includes the heater operation stage under the freeze-off function.
In this embodiment, the refrigerator control method further includes: and acquiring the actual temperature of the evaporator and the preset degraded frost temperature. The defrosting condition is any one of the following conditions: if Ths (actual evaporator temperature) > T1 (preset degradation frost temperature (5-12 ℃)), determining that defrosting is finished, and withdrawing defrosting; or ths (defrosting time) > t1 (the set maximum defrosting time (for example, 10min-60 min)), the defrosting is forcibly exited, and the refrigeration stage is entered.
When the freezing chamber is detected to be opened and then closed under the freezing closing function, the buzzer and the display icon can be set to remind a user that the freezing function is closed; when the user selects to turn on the freezing function under the freezing closing function, the program jumps to the refrigerating and defrosting program under the normal condition.
To sum up, the refrigerator control method of this embodiment increases the refrigerator freezing function of closing, sets for this function and can close the freezing function when the user need not to use the freezer, and the system can carry out the control of compressor and heater according to the refrigeration logic and the logical of defrosting under the corresponding freezing function of closing, not only perfects user's demand, promotes user experience and feels, can practice thrift the power consumption moreover by a wide margin, saves the charges of electricity for the user.
