In addition, sometimes the outdoor temperature is too low, and the indoor temperature is high, when the doors and windows of the user's home are opened, low-temperature air enters the room, and the refrigerator may be heated and cooled down due to sinking of the low-temperature air. When the temperature difference between the upper part and the lower part of the refrigerator reaches a certain difference value, the refrigerant is liquefied at the lower part and flows to the upper high-temperature area to be vaporized, so that the refrigerant passing through the capillary tube or the throttle valve is gaseous refrigerant, the refrigerating effect of the refrigerator is poor, even refrigeration cannot be performed, and the frozen food materials such as meat of a user are thawed and rotten, and the requirements of the user cannot be met.

Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Fig. 1 is a flowchart of a control method of a refrigerating system of a refrigerator according to an embodiment of the present invention, which may include a compressor, a condenser, a capillary tube, an evaporator, etc., and which may further include a refrigerating evaporator and a freezing evaporator, and a refrigerant may reach the condenser from the compressor, reach the capillary tube, reach the evaporator, and finally return to the compressor. Referring to fig. 1, a control method of a refrigerating system of a refrigerator may include the following steps S102 and S104.
Step S102: it is determined whether the refrigeration function of the refrigeration system is disturbed by a heat source in the external environment of the refrigerator.
In this step, it is determined whether the refrigeration function of the refrigeration system is interfered by a heat source in the external environment of the refrigerator, for example, whether the refrigeration function is interfered by a heat source such as an electric heating furnace and a radiator near the outside of the refrigerator, and also, for example, when the indoor temperature is high and the outdoor temperature is low, when a door or window in the user's home is opened, low-temperature air enters the room, and the refrigerator may be heated up and cooled down due to sinking of the low-temperature air, which is also a condition of being interfered by the heat source in the external environment.
If yes, step S104 is executed: the manner in which the refrigeration system operates is adjusted to raise the condensing temperature of the refrigeration system. In this step, generally, the higher the condensing pressure of the refrigeration system, the higher the condensing temperature thereof, and the less susceptible to the external heat source of the refrigerator or the high temperature of the upper portion of the refrigerator, and the more likely the refrigeration effect is achieved. In particular, the condensing temperature of the refrigeration system can generally be raised to a temperature greater than the external heat source of the refrigerator, thereby avoiding vaporization of the refrigerator in the evaporator.
In this embodiment, it is determined whether the refrigeration function of the refrigeration system is interfered by a heat source in the external environment of the refrigerator, if so, the operation mode of the refrigeration system is adjusted to raise the condensation temperature of the refrigeration system, so as to avoid the situation that the refrigeration function of the refrigeration system is interfered by the external heat source of the refrigerator, and the like, thereby ensuring that the liquid refrigerant enters the evaporator to realize the refrigeration effect, avoiding the gaseous refrigerant from entering the evaporator, enabling the refrigeration function of the refrigeration system of the refrigerator to operate normally, and avoiding deterioration after melting frozen food materials. In addition, the invention does not add extra equipment, thereby saving equipment cost.
In one embodiment of the present invention, the step of determining whether the refrigeration function of the refrigeration system is disturbed by a heat source in the environment outside the refrigerator may include:
acquiring a first temperature of a freezing sensor and a second temperature of a defrosting sensor in a refrigerating system;
judging whether the difference between the first temperature and the second temperature is smaller than or equal to a first preset difference;
the step of adjusting the manner of operation of the refrigeration system may include:
judging whether the rotation speed of a compressor in the refrigeration system reaches the maximum rotation speed;
if not, calculating a rotation speed difference value between the rotation speed of the compressor and the maximum rotation speed;
and controlling the rotation speed of the compressor to increase by a specified rotation speed, wherein the specified rotation speed is smaller than or equal to the rotation speed difference value.
In this embodiment, the first preset difference may be set according to practical situations, for example, the first preset difference may be set to any value between 2-3 degrees celsius. If the difference between the first temperature and the second temperature is smaller than or equal to the first preset difference, the refrigeration function of the refrigeration system is interfered by a heat source in the external environment of the refrigerator. Under the condition that the refrigeration function of the refrigeration system is interfered by the external environment of the refrigerator, judging whether the rotation speed of the compressor in the refrigeration system reaches the maximum rotation speed, if not, calculating the rotation speed difference value between the rotation speed of the compressor and the maximum rotation speed, controlling the rotation speed of the compressor to increase the designated rotation speed, and improving the condensation pressure of the refrigeration system, so as to improve the condensation temperature of the refrigeration system, thereby avoiding or reducing the probability that gaseous refrigerant enters the evaporator, ensuring that liquid refrigerant enters the evaporator, realizing the refrigeration effect, enabling the refrigeration function of the refrigeration system of the refrigerator to normally operate, and avoiding deterioration after the frozen food materials are melted.
In one embodiment of the present invention, after the step of controlling the rotation speed of the compressor to increase by a specified rotation speed, the method may further include:
after a preset time period, acquiring a third temperature of the defrosting sensor;
judging whether the difference value between the second temperature and the third temperature is larger than or equal to a second preset difference value;
if yes, outputting first reminding information to remind the user that the power consumption of the refrigerating system under the interference of the external environment of the refrigerator is larger than the normal power consumption.
In this embodiment, after a preset period of time, the third temperature of the defrosting sensor is obtained, and whether the difference between the second temperature and the third temperature is greater than or equal to the second preset difference is determined, if so, it is indicated that the temperature of the defrosting sensor is obviously reduced, that is, it is indicated that after the step of controlling the rotation speed of the compressor to increase the designated rotation speed, the refrigeration system can continue to refrigerate under the interference of the external heat source environment of the refrigerator. At this time, the rotation speed of the compressor is increased, so that the refrigerating system is in a relatively high power consumption state, and the first reminding information is output to remind the user that the power consumption of the refrigerating system under the external environment interference of the refrigerator is greater than the normal power consumption, so that the user can change the position of the refrigerator or the heat source, and the electric energy is saved. The preset time period may be set according to actual needs, for example, an arbitrary value between 5 and 15 minutes, preferably 10 minutes. The second preset difference may be set according to actual needs, for example, any value between 2-10 degrees celsius, preferably 3 degrees celsius. The first reminding information can be output on a display screen of the refrigerator.
In one embodiment of the present invention, if the difference between the second temperature and the third temperature is smaller than the second preset difference, the step of determining whether the rotation speed of the compressor in the refrigeration system reaches the maximum rotation speed is returned.
In this embodiment, if the difference between the second temperature and the third temperature is smaller than the second preset difference, it is indicated that the temperature of the defrosting sensor does not drop significantly, that is, it is indicated that after the step of controlling the rotation speed of the compressor to increase the designated rotation speed, the refrigeration system cannot perform normal refrigeration under the interference of the external heat source environment of the refrigerator. And if not, calculating a rotation speed difference value between the rotation speed of the compressor and the maximum rotation speed, and controlling the rotation speed of the compressor to increase the designated rotation speed so as to continuously increase the condensing pressure of the refrigerating system, further continuously increase the condensing temperature of the refrigerating system and reduce the interference caused by an external heat source of the refrigerator.
In one embodiment of the invention, if the rotation speed of the compressor reaches the maximum rotation speed, a second reminding message is output to remind a user that the refrigerating system cannot refrigerate under the interference of the external environment of the refrigerator.
In this embodiment, if the rotation speed of the compressor reaches the maximum rotation speed, the second reminding information is output to remind the user that the refrigeration system cannot refrigerate under the interference of the external environment of the refrigerator, so that the user can adjust the position of the refrigerator in time, and the frozen food is prevented from melting. The buzzer can sound to output the second reminding information, and the second reminding information can be output through a display screen of the refrigerator.
In one embodiment of the present invention, the step of determining whether the refrigeration function of the refrigeration system is interfered by a heat source in an external environment of the refrigerator may further include:
and judging whether the first temperature is higher than a preset temperature.
In this embodiment, the preset temperature may be understood as a preset cooling temperature. After the refrigerator is started, whether the first temperature of the refrigerating sensor in the refrigerating system is higher than a preset temperature or not, namely, whether the first temperature is higher than the preset temperature or not, if so, the fact that the set refrigerating effect is not achieved is indicated, namely, the refrigerating function of the refrigerating system is interfered by the external environment of the refrigerator, and the judging mode is very simple and effective. Of course, it is also possible to use together as the judgment condition whether the judgment first temperature is greater than the preset temperature and whether the difference between the first temperature and the second temperature is less than or equal to the first preset difference, and the accuracy of the judgment can be improved.
In one embodiment of the present invention, before the step of acquiring the first temperature of the refrigerant sensor and the second temperature of the defrosting sensor in the refrigeration system, the method may further include:
acquiring the working time of a compressor of a refrigeration system;
and when the working time length is greater than or equal to the preset time length, executing the step of acquiring the first temperature of the freezing sensor and the second temperature of the defrosting sensor in the refrigerating system.
In this embodiment, after the refrigerator is started, the refrigerating system needs to run for a period of time to reach the set state, so before the step of obtaining the first temperature of the refrigerating sensor and the second temperature of the defrosting sensor in the refrigerating system, the working time of the compressor of the refrigerating system is obtained, when the working time is longer than or equal to the preset time, the refrigerating system is indicated to reach the stable state, and at this time, the step of obtaining the first temperature of the refrigerating sensor and the second temperature of the defrosting sensor in the refrigerating system is performed, so that the obtained first temperature and second temperature are guaranteed to be the temperatures after the refrigerating system is stable, and whether the refrigerating function of the refrigerating system is interfered by a heat source in the external environment of the refrigerator can be fed back relatively accurately. The working time period may be any value between 1 and 3 hours, for example, may be 2 hours.
In one embodiment of the invention, the specified rotational speed may be any value between 1/5 and 1/2 of the rotational speed difference.
In this embodiment, the specified rotation speed may be any value between 1/5 and 1/2 of the rotation speed difference, for example, 1/3, that is, the specified rotation speed may be obtained according to the rotation speed difference, so that the specified rotation speed may be prevented from being too small, and thus the condensation pressure of the refrigeration system may be raised as soon as possible, so as to raise the condensation temperature as soon as possible, prevent the frozen food material from melting, and avoid the specified rotation speed from being too large, which may result in unnecessary excessive power consumption. In general, the magnitude of the specified rotational speed may be proportional to the magnitude of the rotational speed difference.
In one embodiment of the present invention, the step of adjusting the manner of operation of the refrigeration system may include:
and controlling the bottom air cooler of the refrigerating system to stop rotating.
In this embodiment, the bottom air cooler of the refrigeration system is controlled to stop rotating, so that the condensation pressure and the condensation temperature can be improved, and the frozen food material is prevented from being melted. Specifically, after the bottom air cooler stops rotating, the third temperature of the defrosting sensor can be obtained after a preset time period, whether the difference value between the second temperature and the third temperature is larger than or equal to a second preset difference value is judged, if yes, first reminding information is output to remind a user that the power consumption of the refrigerating system under the interference of the external environment of the refrigerator is larger than the normal power consumption, if not, whether the rotating speed of the compressor in the refrigerating system reaches the maximum rotating speed is judged, if not, the rotating speed difference value between the rotating speed of the compressor and the maximum rotating speed is calculated, the rotating speed of the compressor is controlled to be increased by a specified rotating speed, and the specified rotating speed is smaller than or equal to the rotating speed difference value.
