In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. The indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the indicated device or element must have a specific orientation or a specific orientation. construction and operation, and therefore should not be construed as limiting the invention.

One of the objectives of the present invention is to provide a control method for the pressure balance of a refrigerator, which is used to overcome the increase of negative pressure in the freezer compartment after the door of the freezer compartment of the refrigerator is closed, and the pressure inside and outside the freezer compartment is unequal, thereby causing the freezer compartment door to be opened again. It requires a lot of strength when the body is opened, and there is a problem of difficulty in opening the door twice.

As shown in FIG. 1 , the pressure balance control method 10 of a refrigerator includes:

Obtain the door closing signal of the freezer compartment door of the refrigerator; and

Control the opening of the ice outlet cover on the door of the refrigerator to allow outside air to enter the freezer compartment of the refrigerator.

In this embodiment, the refrigerator includes a freezing compartment and a refrigerating compartment. A freezing compartment door is arranged on the front side of the freezing compartment, a refrigerating compartment door is arranged on the front side of the refrigerating compartment, and the ice maker is arranged on the refrigerating compartment door. Among them, the ice outlet cover plate of the ice maker is arranged on the front side of the refrigerating compartment door body.

The return air duct of the ice maker is arranged on the insulation layer between the inner tank and the box of the refrigerator, and the opposite ends of the return air duct of the ice maker are respectively connected to the freezing compartment and the ice making compartment of the ice maker. The air enters the ice-making room from the ice outlet cover, and then enters the freezing room through the ice-making return air duct. The high-temperature air in the external environment enters the freezing room to reduce the freezing room caused by the closing of the freezing room door Indoor negative pressure, when the freezer door is opened again, the freezer door can be opened smoothly.

In a preferred embodiment of the present invention, the above-mentioned step of acquiring the door closing signal of the freezer compartment door of the refrigerator includes:

Obtain the door opening signal of the freezer compartment door of the refrigerator, and record the door opening time;

Obtain the door closing signal of the freezer compartment door of the refrigerator, and record the closing time; and

A time interval between the door opening time and the door closing time is calculated.

In this embodiment, the door opening time and door closing time of the freezer compartment door of the refrigerator are obtained, and the time interval between the door opening and closing of the freezer compartment door is calculated. closure.

Among them, if it is determined that the door of the freezer compartment is opened and closed in a short time, it means that the room temperature gas in the external environment enters the freezer compartment and cools down in the freezer compartment, resulting in a decrease in the pressure in the freezer compartment, forming a negative pressure. Therefore, when the external ambient temperature is higher, the interval between opening and closing the door is shorter, the greater the negative pressure formed in the freezer compartment, and the greater the force required to open the freezer compartment door again. , it is more difficult to open the door.

In addition, if it is determined that the freezer compartment door is not opened and closed in a short time, that is, the freezer compartment door is opened for a long time and then closed, wherein the room temperature gas in the external environment continues to enter the freezer compartment, and the air inside the freezer compartment When the temperature rises, even if the door of the freezer is closed, since the temperature in the freezer has risen, the pressure difference between the external pressure and the internal pressure of the freezer is not large, so it is not easy to open the door twice.

In other words, the pressure balance control method 10 of the refrigerator provided by the present invention is particularly suitable for opening and closing the door in a short period of time, resulting in the problem that the door is not easy to open due to inconsistent internal and external pressure differences when the door is opened again.

In addition, in the pressure balance control method 10 of the refrigerator, the step of controlling the opening of the ice outlet cover on the door of the refrigerator includes:

Control the opening time of the ice outlet cover according to the time interval;

Wherein, the shorter the time interval, the longer the opening time of the ice outlet cover.

That is, there is a negative correlation between the opening time of the ice outlet cover and the above-mentioned time interval between opening and closing the door. The main reason is that the shorter the time interval, the greater the negative pressure in the freezer compartment, and the greater the pressure difference between the inside and outside of the freezer compartment. Therefore, by prolonging the opening time of the ice outlet cover, there is more air in the outside environment. It can quickly overcome the problem of excessive negative pressure in the freezing room and facilitate the opening of the door for the second time.

In other embodiments of the present invention, the step of controlling the opening of the ice outlet cover on the door of the refrigerator further includes:

comparing said time interval with a preset time;

If the time interval is less than the preset time, the ice outlet cover on the door body of the refrigerator is controlled to open.

In a preferred embodiment, if the time interval is less than the preset time, the opening time of the ice outlet cover on the door of the refrigerator is controlled to be the first preset time.

In this embodiment, when the time interval between opening and closing the door is less than the preset time, it means that the door opening time of the freezer compartment is short, and the pressure difference between the inside and outside of the freezer compartment is large after the freezer door is closed. Wherein, the opening time of the ice outlet cover plate on the door body of the refrigerator is controlled to be the 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 opening and closing the door is less than the preset time, the number of times the ice outlet cover is opened can also be controlled to overcome the problem of different internal and external pressure differences. In other words, within a certain time range, repeatedly open and close the ice outlet cover.

In a preferred embodiment, if the time interval is greater than the preset time, the ice outlet cover on the door of the refrigerator is kept closed, or the opening time of the ice outlet cover on the door of the refrigerator is controlled to be the second time. set time.

Preferably, the second preset time is shorter than the first preset time.

In this embodiment, when the time interval between opening and closing the door exceeds the preset time, it means that the door opening time of the freezer compartment is relatively long, and after the door body of the freezer compartment is closed, the pressure difference between the inside and outside of the freezer compartment is small or almost near. Among them, when the difference between the internal and external pressures is small, the ice outlet cover can be opened for a short time (corresponding to the second preset time); when the difference between the internal and external pressures is almost close, the ice outlet cover can be kept closed. That is, the ice outlet cover is not opened.

The present invention also provides an electronic device including a memory and a processor, wherein the memory stores a computer program that can be run on the processor, and the processor implements the above-mentioned pressure balance control method 10 for a refrigerator when the computer program is executed.

As shown in FIG. 2 to FIG. 4 , the present invention further provides a refrigerator 100 , which includes a freezer compartment door 110 , a refrigerator compartment door 120 and an ice maker 130 , and the ice maker 130 is arranged on the refrigerator compartment door 120 . The ice maker 130 further includes an ice outlet cover 131 and an ice maker return air duct 132 . The ice outlet cover 131 is arranged on the front side of the refrigerating compartment door 120 , and the ice maker return duct 132 is arranged on the front side of the refrigerator 100 . Between the inner tank and the casing, opposite ends of the ice-making machine return air duct 132 are respectively connected to the ice-making compartment and the freezing compartment 140 .

The refrigerator 100 further includes a control main board, which is used for executing all the steps in the above-mentioned pressure balance control method 10 of the refrigerator.

Specifically, after detecting the door closing signal of the freezer compartment door 110, the control mainboard outputs a control signal to control the ice outlet cover 131 of the ice maker 130 to open, so that outside air enters the ice making compartment, and passes through the ice maker. The return air duct flows into the freezer compartment 140 to reduce the problem of excessive negative pressure caused by opening and closing the door in a short time in the freezer compartment 140, so as to facilitate the second opening of the freezer compartment door.

It should be noted that, in the refrigerator 100 , a freezing evaporator is provided at the freezing compartment 140 , and an ice making fan for blowing air toward the ice making compartment at the refrigerating compartment door 120 is provided at the freezing evaporator. The front side of the refrigerating evaporator is provided with a refrigerating chamber air duct and a refrigerating fan that provide cooling capacity toward the refrigerating chamber 140 .

One side of the freezing compartment 140 and the refrigerating compartment 150 of the inner tank is provided with an ice maker air duct 133 and an ice maker return air for delivering cold energy to the ice maker 130 of the refrigerating door body 120 A duct 132 , wherein the ice maker air supply duct 133 is connected with the ice maker fan, and the ice maker return air duct 132 is communicated with the freezing compartment 140 .

On one side of the refrigerating compartment 150 , the ice maker air supply duct 133 and the ice maker return air duct 132 are respectively communicated with the air supply port and the air return port of the refrigerating door 120 .

In addition, the refrigerating door body 120 where the ice maker 130 is located has an ice outlet that communicates with the outside world, and the ice outlet is sealed with an ice outlet cover plate 131 . The ice outlet cover 131 is, for example, the dispenser cover 131 .

When the refrigerator 100 is running stably, the ice-making fan is running, the ice-making machine air supply duct 133 delivers cold energy to the ice-making compartment of the ice-making machine 130 on the refrigerating compartment door 120 for making ice, and the air circulates through the ice-making machine to return to the ice-making compartment. The air duct 132 returns to the freezing compartment 140, and then passes through the refrigeration return air duct of the refrigerating air duct to the refrigerating evaporator.

In this embodiment, when the ice-making fan is running, in order to prevent the partial frost of the evaporator from being severely frosted and unevenly distributed in the evaporator, it is required that the freezing fan must be in the running state when the ice-making fan is running.

In addition, when the freezing compartment door body 110 is opened, both the freezing fan and the ice making fan are turned off.

After the freezer compartment door 110 is opened and closed in a short period of time, due to the thermal expansion and contraction of the air, the negative pressure inside the freezer compartment 140 is large, and the force required to open the freezer compartment door 110 next time is very large. 140 The pressure difference between inside and outside is too large, which leads to the problem of inconvenient door opening. After the distributor cover 131 is opened, since the ice-making fan in the ice-making compartment starts to operate, the outside air enters the freezing compartment 140 through the ice-making machine return air duct 132 to neutralize the negative pressure state, thereby reducing the next door opening force. .

In summary, the present invention provides a pressure balance control method for a refrigerator, an electronic device and a refrigerator. When the door closing signal of the freezer compartment door body of the refrigerator is detected, the ice outlet cover of the ice maker on the freezer compartment door body is controlled to open. , By introducing external room temperature air into the freezer compartment, to overcome the problem that the freezer compartment door is not easy to open twice due to the large negative pressure caused by opening and closing the door in a short time.
