In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The invention aims to provide a method for controlling pressure balance of a refrigerator, which is used for overcoming the problems that after a door body of a freezing chamber of the refrigerator is closed, negative pressure in the freezing chamber is increased, internal and external pressures are unequal, and further, when the door body of the freezing chamber is opened again, very large force is needed, and secondary door opening is difficult.
As shown in fig. 1, a pressure balance control method 10 of a refrigerator includes:
acquiring a door closing signal of a freezing chamber door body of the refrigerator; and
and controlling an ice outlet cover plate on a door body of the refrigerator to be opened so as to enable external air to enter a freezing chamber of the refrigerator.
In this embodiment, the refrigerator includes a freezing chamber and a refrigerating chamber, a freezing chamber door is disposed on a front side of the freezing chamber, a refrigerating chamber door is disposed on a front side of the refrigerating chamber, the ice maker is disposed in the refrigerating chamber door, and an ice outlet cover plate of the ice maker is disposed on a front side of the refrigerating chamber door.
The air return duct of the ice maker is arranged on the heat insulation layer between the inner container and the refrigerator body of the refrigerator, and two opposite ends of the air return duct of the ice maker are respectively communicated with the freezing chamber and the ice making chamber of the ice maker, so that outside air enters the ice making chamber from the ice outlet cover plate and then enters the freezing chamber through the air return duct of the ice maker, high-temperature air in the outside environment enters the freezing chamber and is used for reducing negative pressure in the freezing chamber caused by closing of the door body of the freezing chamber, and when the door body of the freezing chamber is opened again, the door body of the freezing chamber can be opened smoothly.
In a preferred embodiment of the present invention, the step of obtaining the door closing signal of the freezing chamber door of the refrigerator includes:
acquiring a door opening signal of a freezing chamber door body of the refrigerator, and recording the door opening time;
acquiring a door closing signal of a freezing chamber door body of the refrigerator, and recording the door closing time; and
calculating the time interval between the door opening time and the door closing time.
In this embodiment, the door opening time and the door closing time of the freezing chamber door body of the refrigerator are obtained, the time interval between the door opening and the door closing of the freezing chamber door body is calculated, and accordingly, whether the freezing chamber door body of the refrigerator is opened and closed in a short time can be judged.
If the door body of the freezing chamber is judged to be opened and closed in a short time, the room temperature gas in the external environment enters the freezing chamber, the temperature in the freezing chamber is reduced, the pressure in the freezing chamber is reduced, and negative pressure is formed. Therefore, when the external environment temperature is higher, the shorter the interval between the door opening and the door closing, the greater the negative pressure formed in the freezing compartment, and the greater the force required to open the door of the freezing compartment again, and the less the door is opened.
In addition, if the door body of the freezing chamber is judged not to be opened and closed in a short time, namely, the door body of the freezing chamber is closed after being opened for a long time, wherein the room temperature gas in the external environment continuously enters the freezing chamber, the temperature in the freezing chamber rises, and even if the door body of the freezing chamber is closed, the pressure difference between the external pressure and the internal pressure of the freezing chamber is not large, so that the problem of difficulty in opening the door for the second time is not easy to occur.
In other words, the pressure balance control method 10 of the refrigerator according to the present invention is particularly suitable for solving the problem that the door body is not easily opened due to the inconsistent internal and external pressure differences when the door is opened again because the door is opened and closed in a short time.
In addition, in the pressure balance control method 10 of the refrigerator, the step of controlling the ice outlet cover plate on the door body of the refrigerator to be opened includes:
controlling the opening time of the ice outlet cover plate according to the time interval;
wherein the shorter the time interval, the longer the opening time of the ice outlet cover plate.
That is, the opening time of the ice outlet cover and the time interval between the opening and closing of the door are inversely related. The main reason lies in, the time interval is shorter, has caused the indoor negative pressure of freezing room big more, and then the indoor inside and outside pressure differential of freezing room is big more, consequently, through the open time of extension ice outlet cover plate for the more entering of air in the external environment makes the ice room, via the ice machine return air duct, gets into freezing room, and the too big problem of indoor negative pressure of overcoming freezing room that can be quick is convenient for the secondary and opens the door.
In another embodiment of the present invention, the step of controlling the opening of the ice outlet cover plate on the door body of the refrigerator further includes:
comparing the time interval with a preset time;
and if the time interval is less than the preset time, controlling an ice outlet cover plate on a door body of the refrigerator to be opened.
In a preferred embodiment, if the time interval is less than the preset time, the opening time of the ice outlet cover plate on the door body of the refrigerator is controlled to be a first set time.
In this embodiment, when the time interval between the door opening and the door closing is less than the preset time, it indicates that the door opening time of the freezing chamber door body is short, and after the door of the freezing chamber door body is closed, the internal and external pressure difference value of the freezing chamber is large. The opening time of an ice outlet cover plate on a door body of the refrigerator is controlled to be first set time. The first set time is, for example, a long time.
In other embodiments of the present invention, when the time interval between the opening and closing of the door is less than the preset time, the opening times of the ice outlet cover plate can be controlled to overcome the problem of different internal and external pressure difference values. In other words, the ice outlet cover is repeatedly opened and closed a plurality of times within a certain time range.
In a preferred embodiment, if the time interval is greater than the preset time, the ice outlet cover plate on the door body of the refrigerator is kept closed, or the opening time of the ice outlet cover plate on the door body of the refrigerator is controlled to be the second set time.
Preferably, the second preset time is less than the first preset time.
In this embodiment, when the time interval between the door opening and the door closing exceeds the preset time, it indicates that the door opening time of the freezing chamber door body is longer, and after the door of the freezing chamber door body is closed, the value of the pressure difference between the inside and the outside of the freezing chamber is smaller or almost close. Wherein, the ice outlet cover plate can be opened in a short time (corresponding to a second preset time) under the condition that the internal and external pressure difference value is smaller; in the case of an almost approximate difference between the internal and external pressure, the ice outlet cover plate can be maintained closed, i.e., not opened.
The invention also provides an electronic device, which comprises a memory and a processor, wherein the memory stores a computer program capable of running on the processor, and the processor executes the computer program to realize the pressure balance control method 10 of the refrigerator.
As shown in fig. 2 to 4, the present invention further provides a refrigerator 100, which includes a freezing chamber door 110, a refrigerating chamber door 120, and an ice maker 130, wherein the ice maker 130 is disposed on the refrigerating chamber door 120, the ice maker 130 further includes an ice outlet cover plate 131 and an ice maker return duct 132, the ice outlet cover plate 131 is disposed on the front side of the refrigerating chamber door 120, the ice maker return duct 132 is disposed between the inner container and the housing of the refrigerator 100, and two opposite ends of the ice maker return duct 132 are respectively communicated with the ice making chamber and the freezing chamber 140.
The refrigerator 100 further includes a control main board for performing all the steps of the pressure balance control method 10 of the refrigerator described above.
Specifically, after detecting the door closing signal of the freezing chamber door 110, the control main board outputs a control signal to control the ice outlet cover plate 131 of the ice maker 130 to open, so that the outside air enters the ice making chamber and flows into the freezing chamber 140 through the ice maker return air duct, thereby reducing the problem of excessive negative pressure of the freezing chamber 140 caused by opening and closing the door in a short time, and facilitating the secondary opening of the freezing chamber door.
In the refrigerator 100, a freezing evaporator is provided in the freezing compartment 140, and an ice making fan for blowing air into the ice making compartment in the refrigerating compartment door 120 is provided in the freezing evaporator. The front side of the freezing evaporator is provided with a freezing chamber air duct and a freezing fan which provide cooling energy towards the freezing chamber 140.
An ice maker air supply duct 133 and an ice maker air return duct 132 for conveying cold energy to the ice making chamber of the ice maker 130 of the refrigerating door 120 are arranged on one side of the freezing chamber 140 and one side of the refrigerating chamber 150 of the inner container, wherein the ice maker air supply duct 133 is connected with an ice making fan, and the ice maker air return duct 132 is communicated with the freezing chamber 140.
On one side of the refrigerating compartment 150, the air supply duct 133 of the ice maker and the air return duct 132 of the ice maker are respectively communicated with the air supply outlet and the air return inlet of the refrigerating door 120.
In addition, an ice outlet communicated with the outside is formed in the refrigerating door 120 where the ice maker 130 is located, and the ice outlet is sealed by an ice outlet cover plate 131. The ice outlet cover 131 is, for example, a dispenser cover 131.
When the refrigerator 100 is stably operated, the ice making fan is operated, the ice making air duct 133 supplies cold energy to the ice making chamber of the ice making machine 130 on the refrigerating chamber door 120 to make ice, and the air circulates through the ice making machine return duct 132 to the freezing chamber 140 and then flows through the freezing air duct to the freezing evaporator.
In this embodiment, when the ice making fan operates, in order to avoid the situation that the frosting distribution of the evaporator is not uniform due to the fact that the local frosting of the evaporator is serious, the freezing fan needs to be in an operating state when the ice making fan operates.
In addition, when the freezing chamber door body 110 is opened, both the freezing fan and the ice making fan are turned off.
After the freezing chamber door body 110 is opened and closed in a short time, negative pressure inside the freezing chamber 140 is large due to expansion and contraction of air, and the force required for opening the freezing chamber door body 110 next time is very large, so that the problem of inconvenient door opening caused by too large pressure difference inside and outside the freezing chamber 140 is solved. After the dispenser cover 131 is opened, since the ice making fan of the ice making compartment starts to operate, the external air enters the freezing compartment 140 through the ice making machine return duct 132 to neutralize the negative pressure state, thereby reducing the door opening force next time.
In summary, the invention provides a pressure balance control method for a refrigerator, an electronic device and a refrigerator, when a door closing signal of a freezing chamber door body of the refrigerator is detected, an ice outlet cover plate of an ice maker on the freezing chamber door body is controlled to be opened, and external room temperature air is introduced into a freezing chamber, so that the problems that negative pressure of the freezing chamber is high due to opening and closing the door in a short time, and the freezing chamber door body is not easy to open for the second time are solved.
