The air curtain air opening 7 and the at least one air outlet 8 can be provided with a switch door for controlling the opening and closing of the air opening. Specifically, a first switch door 61 is arranged at the air curtain air port 7, when the first switch door 61 is opened, the air curtain air port 7 is opened, and when the first switch door 61 is closed, the air curtain air port 7 is closed; the air outlet 8 is provided with a second switch door 62, the second switch door 62 is opened, the corresponding air outlet 8 is opened, the second switch door 62 is closed, and the corresponding air outlet 8 is closed.

Fig. 4 is a flowchart of a refrigerator control method according to an embodiment of the present invention, and as shown in fig. 4, the method includes the following steps:

s401, judging whether the refrigerating demands of all the compartments of the refrigerator are synchronous or not.

S402, if not, controlling the compressor, the fan 3 and the at least one air outlet 8 according to whether the compartment where the top air duct 21 is located has a refrigeration demand, and controlling the air curtain air inlet 7 to be in an opening state, so that each compartment is in a respective preset temperature range when the compressor is stopped.

The refrigerator has a refrigerating compartment with a starting point temperature and a stopping point temperature, wherein the starting point temperature and the stopping point temperature of each compartment of the refrigerator are respectively corresponding to the refrigerating compartment, for example, the stopping point temperature of the refrigerating compartment is 4 ℃, the starting point temperature is 6 ℃, the stopping point temperature of the freezing compartment is-20 ℃, and the starting point temperature is-18 ℃.

Whether the refrigerator compartment has a refrigeration requirement or not can be determined by combining the current state of the compressor and the temperature of the starting point and the stopping point of the compartment. For example, if the current compressor is in an on state, i.e., the refrigerator is refrigerating, the compartment temperature will gradually decrease, and in the process, the compartment temperature is less than or equal to the stop point temperature, the compartment has no refrigeration requirement, the compartment temperature is greater than the stop point temperature, and the compartment has a refrigeration requirement. If the current compressor is in a shutdown state, the compartment temperature gradually rises, in the process, the compartment temperature is less than the starting point temperature, the compartment has no refrigeration requirement, the compartment temperature is greater than or equal to the starting point temperature, and the compartment has the refrigeration requirement. The compartment has a refrigeration demand indicating that the compartment has no shutdown request.

The synchronous refrigeration requirements of all the compartments of the refrigerator mean that all the compartments have refrigeration requirements at the same time, or all the compartments have no refrigeration requirements at the same time. The asynchronous refrigeration requirements of each compartment of the refrigerator mean that the compartments have refrigeration requirements and the compartments have no refrigeration requirements at the same time.

The compartment temperature is within a preset temperature range of the compartment, which means that the compartment temperature is stable around the set temperature and the fluctuation range is within an allowable range, for example, the compartment temperature is maintained to fluctuate by 0.5 degrees above and below the set temperature.

This embodiment is when the room shut down request is asynchronous, whether have the refrigeration demand to control the compressor according to top wind channel 21 place room, fan 3 and the opening and closing of wind gap that sets up at top wind channel 21, so that each room all is in respective predetermined temperature range when the compressor is shut down, can accelerate the refrigeration efficiency of this room when there is the refrigeration demand in top wind channel 21 place room, avoid other room temperature that do not have the refrigeration demand too low, make this room temperature rise in certain extent when there is not the refrigeration demand in top wind channel 21 place room, need not extra device alright reach the purpose of delaying the compressor shut down, practice thrift the energy consumption and can reduce the unnecessary heat.

It should be noted that the method according to the embodiments of the present invention can be used to control the operation of the refrigerator regardless of which compartment controls the compressor to be turned on or off according to the temperature of the compartment. The embodiment of the invention is mainly used for controlling the compressor to stop in the refrigeration process of the refrigerator.

In one embodiment, the controlling of the compressor, the fan 3 and the at least one air outlet 8 according to whether there is a refrigeration requirement in the compartment in which the top air duct 21 is located comprises: if the compartment where the top air duct 21 is located has no refrigeration requirement, controlling the compressor to be in an open state, reducing the rotating speed of the fan 3, and controlling at least one air outlet 8 to be in a closed state; when all other compartments have no cooling demand, the compressor and the fan 3 are switched off. The rotation speed of the fan 3 may be reduced by a preset adjustment range, for example, a first gear is reduced. When all other compartments have no refrigeration requirement, the air curtain air opening 7 and the air outlet 8 can be kept in the current state or can be completely closed because the compressor and the fan 3 are closed.

The top wind channel 21 does not have the refrigeration demand in the room, but there is the room still to have the refrigeration demand in other rooms, at this moment, 3 rotational speeds of fan reduce, second switch door 62 is closed, first switch door 61 is opened, open air curtain wind gap 7 and close all air outlets 8 simultaneously promptly, when reducing the cold wind volume with fan 3, cold wind forms the major cycle in the room from air-out in air curtain wind gap 7, under the prerequisite that can not influence the fresh-keeping effect of room, with this make top wind channel 21 room temperature rise in certain extent, thereby need not extra device and can postpone compressor down time, save the energy consumption, reduce the unnecessary heat.

Further, after controlling the compressor to be in an on state, reducing the rotational speed of the fan 3, and controlling at least one air outlet 8 to be in an off state, the method further comprises: if the preset time is reached and other compartments still have refrigeration requirements, the compressor and the fan 3 are turned off. The preset time can be set according to actual conditions, for example, the preset time is set to be 3-5 min.

If no refrigerating requirement exists in other chambers within the preset time, the compressor is directly stopped. If after reaching the preset time, still there is the refrigeration demand in the compartment, the compressor is shut down when reaching the preset time, and is equivalent to, the compressor delays the preset time and shuts down to avoid the compressor to operate for a long time and lead to power consumption to increase.

In one embodiment, the controlling of the compressor, the fan 3 and the at least one air outlet 8 according to whether there is a refrigeration requirement in the compartment in which the top air duct 21 is located comprises: if the compartment where the top air duct 21 is located has a refrigeration requirement, controlling the compressor to be in an open state, increasing the rotating speed of the fan 3, and controlling at least one air outlet 8 to be in an open state; and when the compartment where the top air duct 21 is located has no refrigeration requirement, returning to the step of judging whether the refrigeration requirements of the compartments of the refrigerator are synchronous or not so as to control by combining the temperature conditions of other compartments. The rotation speed of the fan 3 may be increased by a predetermined adjustment range, for example, by a first gear.

There is the refrigeration demand in the room of top wind channel 21 place, but there is the room to have in other rooms and do not have the refrigeration demand, need accelerate the refrigeration of the room of top wind channel 21 place this moment, in order to shorten the refrigeration time of the room that does not have the refrigeration demand, it is concrete, fan 3 rotational speed improves one shelves, first switch door 61 and second switch door 62 are opened simultaneously (be that wind curtain wind gap 7 and at least one air outlet 8 are all in the open mode), thereby accelerate the refrigeration efficiency in the room of top wind channel 21 place, shorten the refrigeration time of the room of other no refrigeration demands, avoid other rooms temperature to hang down excessively, and energy consumption is saved. When increasing the cold wind volume with fan 3, open air curtain wind gap 7, share the cold volume of air outlet 8, avoid leading to cold volume gathering at the superiors 'shelf because of the increase of 3 rotational speeds of fan to avoid the too big problem of upper and lower floor's difference in temperature.

And under the condition that all the compartments have refrigeration requirements, the compressor and the fan 3 are controlled to be in an opening state, the air curtain air opening 7 is controlled to be in a closing state, and the at least one air outlet 8 is controlled to be in an opening state. When all the compartments have refrigeration requirements, namely, in a normal refrigeration running state, the compressor is started, the fan 3 is started, the first switch door 61 is closed (namely, the air curtain air inlet 7 is in a closed state), the second switch door 62 is opened (namely, at least one air outlet 8 is in an open state), cold air is mainly concentrated at the air outlet 8, the cold air is gathered around the shelf 10, and the refrigeration and fresh-keeping effects are improved. And, the air outlet 8 sets to inclination, avoids cold wind direct-blow and prevents that the highest shelf from hindering cold wind to sink, guarantees that cold wind sends to lower floor's shelf before/after the upper shelf, the balanced cold volume.

It should be noted that, in the above steps, the wind curtain air port 7 and the wind outlet 8 can be controlled simultaneously.

The specific control of the refrigerator is described below with reference to a specific embodiment, however, it should be noted that the specific embodiment is only for better describing the present application and is not to be construed as limiting the present application.

As shown in fig. 5, which is a specific control flowchart of a refrigerator, in this embodiment, the refrigerator includes a refrigerating compartment and a freezing compartment, the top air duct 21 is disposed in the refrigerating compartment, and the compressor is controlled to start and stop according to the temperature of the refrigerating compartment, and the delayed stop of the compressor can be realized when the stop requests of different compartments are not synchronous through the control flowchart shown in fig. 5. The method specifically comprises the following steps:

s501, a freezing chamber temperature Td detected by the freezing chamber temperature sensor is acquired.

S502, whether Td is more than or equal to T1 is judged, if yes, S503 is entered, and if no, S504 is entered. T1 is the preset value of the refrigeration demand of the freezing chamber (which can be the starting point temperature or the stopping point temperature of the freezing chamber), when Td is more than or equal to T1, the freezing chamber has the refrigeration demand.

S503, the freezer compartment has a refrigeration demand, and the process proceeds to S506.

S504, no refrigeration demand is placed in the freezer compartment, and S506 is entered.

And S505, acquiring the refrigerating chamber temperature Tc detected by the refrigerating chamber temperature sensor.

S506, judging whether Tc is more than or equal to T2, if yes, entering S507, and if no, entering S515. T2 is the preset value of the refrigerating chamber with the refrigerating requirement (which can be the starting point temperature or the stopping point temperature of the refrigerating chamber), when Tc is more than or equal to T2, the refrigerating chamber has the refrigerating requirement.

S507, the refrigerating compartment has a refrigerating requirement, and the process proceeds to S508.

And S508, judging whether the refrigerating chamber and the freezing chamber both have refrigerating requirements, if so, entering S509, and if not, entering S512.

S509, the compressor is started.

S510, the first opening/closing door 61 is closed.

S511, the second switching door 62 is opened. When all the compartments have refrigeration requirements, namely, in a normal refrigeration running state, cold air is mainly concentrated at the air outlet 8 and is gathered around the shelf 10, so that the refrigeration and fresh-keeping effects are improved. And, the air outlet 8 sets to inclination, avoids cold wind direct-blow and prevents that the highest shelf from hindering cold wind to sink, guarantees that cold wind sends to lower floor's shelf before/after the upper shelf, the balanced cold volume.

S512, the compressor is kept on.

And S513, increasing the rotation speed of the fan 3 by one gear.

And S514, opening the first switch door 61 and the second switch door 62. When the refrigerating chamber has a refrigerating requirement, the compressor continuously operates, and the freezing chamber has no refrigerating requirement, the refrigerating chamber is accelerated to reach a stop point, the refrigerating time of the freezing chamber is shortened, the rotating speed of the fan 3 is increased by one gear, and the first switch door 61 and the second switch door 62 are opened simultaneously. When fan 3 increases the cold wind volume, open air curtain wind gap 7, share the cold volume of all the other air outlets 8, avoid leading to cold volume gathering at the superiors' shelf because of the rotational speed increase, avoid the too big problem of upper and lower layer difference in temperature.

S515, there is no refrigeration demand in the refrigerated compartment, and proceed to S516.

And S516, judging whether the refrigerating chamber and the freezing chamber have no refrigerating requirements, if so, entering S517, and if not, entering S518.

And S517, stopping the compressor.

S518, the compressor is kept on, and the shutdown is delayed.

And S519, reducing the rotation speed of the fan 3 by one gear.

S520, the second switching door 62 is closed.

S521, the first opening/closing door 61 is opened. When the refrigerating chamber has no refrigerating requirement, the compressor is stopped, but the refrigerating chamber still has the refrigerating requirement, the compressor is kept on to delay the stop, the rotating speed of the fan 3 is reduced by the first gear, the second switch door 62 is closed, and the first switch door 61 is opened. When reducing the cold wind volume with fan 3, through opening air curtain wind gap 7, do not influence the fresh-keeping effect of cold-stored room to this lets cold-stored room temperature rise in certain extent, postpones compressor down time.

In daily life, most of articles stored in the refrigerator belong to daily necessities, such as vegetables, fruits, drinks and the like. The frequency of opening the refrigerator is frequent in one day, and the frequency is more frequent under the condition that children exist at home, so that the burden of the compressor is increased, the exchange of cold and hot loads inside and outside the compartment is increased, and the energy consumption is increased.

The embodiment of the invention can reduce the cold and hot load exchange between the interior and the exterior of the refrigerator door during the opening time through the air curtain air opening 7. Specifically, the method may further include: detecting the tendency of the door of the compartment in which the top air duct 21 is located to be opened; controlling the fan 3 to be in an operating state and controlling at least one air outlet 8 to be in a closed state; and controlling the air curtain air port 7 to be in an opening state.

For example, the compartment door is provided with a door suction device, and when the door suction device detects that external force is applied to resist the door suction state, the compartment door is considered to have the tendency of being opened; for another example, a room lamp 4 and a door lamp switch 9 are generally arranged in a room, a room door is closed, a protruding portion of the door lamp switch 9 is pressed down by a door edge, the switch is turned off, the room lamp 4 is turned off, the room door is opened, the protruding portion of the door lamp switch 9 automatically pops up, a circuit is closed and powered on, the room lamp 4 is turned on, that is, the door lamp switch 9 is triggered when the room door is opened, and whether the room door has a tendency of being opened or not can be determined by detecting the change of the door lamp switch 9.

The fan 3 is controlled to be in an operating state, the at least one air outlet 8 is controlled to be in a closed state, cold air can be stored in the top air channel 21, the efficiency of reducing the cold and hot load exchange of the internal air and the external air is improved, the fan 3 stirs the original air in the compartment, and the temperature of the compartment is kept balanced as much as possible. Then the air curtain air port 7 close to the refrigerator door is controlled to be in an opening state, and the cold air stored in the top air channel 21 naturally droops from the air curtain air port 7 under the action of gravity and attraction force during opening the door to form a curtain, so that the heat exchange between the heat load in the environment and the cold load in the room is reduced when the door is opened, the food fresh-keeping and refrigerating effects are prevented from being influenced, and the energy consumption of the refrigerator can be reduced.

Further, after controlling the air curtain air opening 7 to be in the opening state, the method further comprises: when the door of the compartment where the top air duct 21 is located is opened, the fan 3 is controlled to stop running, so that the somatosensory noise of the opened refrigerator door can be reduced, and the comfort of a user when the user uses the refrigerator is improved. When the compartment door is closed, the fan 3 returns to the state before the door is opened.

It should be noted that, if the door is opened, the compressor and the fan 3 are in the off state, the fan 3 can be kept in the current off state when the door is opened, and the fan 3 and the air curtain opening 7 can be opened to send out the residual cold in the air duct 2 through the air curtain opening 7, so as to reduce the indoor and outdoor heat exchange during the door opening time.

The specific control of the door is described below with reference to a specific embodiment, however, it should be noted that the specific embodiment is only for better describing the present application and is not to be construed as limiting the present application.

As shown in fig. 6, which is a specific control flowchart when the refrigerator is opened, taking the top air duct 21 disposed in the refrigerating compartment and the door of the refrigerating compartment opened as an example, the method includes the following steps:

s601, whether the trend that the door of the refrigerating compartment is opened is detected, if yes, the step goes to S602, and if not, the step goes to S607.

And S602, triggering the door lamp switch 9.

S603, the second switch door 62 is closed, and the cold air which is originally required to come out from the air outlet 8 is pre-stored in the top air duct 21, so that more cold energy is generated by means of drooping under the action of gravity when the air curtain air port 7 is opened, and the efficiency of reducing the cold and heat load exchange of the inside air and the outside air is improved. Meanwhile, the fan 3 keeps running state, stirs the original air in the chamber, and keeps the cold quantity of the chamber uniform.

S604, the first switch door 61 is opened, and the pre-stored cold energy begins to sink.

S605, at the moment when the compartment door is opened, the fan 3 is closed to reduce the body-sensory noise after the compartment door is opened.

And S606, turning on the compartment lamp 4.

S607, the door lamp switch 9 remains in the off state.

S608, the opening and closing of the first opening and closing door 61 and the second opening and closing door 62 are controlled according to the flow shown in fig. 5.

S609, the compartment lamp 4 remains off.
