and controlling each evaporator fan according to the operation mode, the temperature of each compartment and the temperature of each evaporator.
The invention provides a three-system refrigerator which comprises three refrigerating chambers, namely a freezing chamber, a refrigerating chamber and a temperature changing chamber. Each compartment is independently refrigerated by a corresponding evaporator, and the cold energy generated by the evaporator is transferred into the compartment through a corresponding evaporator fan, for example, the cold energy generated by the refrigeration of the refrigeration evaporator is transferred into the refrigeration compartment by a refrigeration fan to finish the refrigeration of the refrigeration compartment. When the fan of the evaporator is closed, the air duct is closed to prevent cold from flowing back to the evaporator. And each chamber is internally provided with a corresponding chamber temperature sensor for detecting the temperature in the chamber, and each evaporator is provided with a corresponding defrosting temperature sensor for detecting the temperature of the evaporator. Generally, the refrigerating chamber is disposed above the refrigerator, the temperature-changing chamber is disposed in the middle of the refrigerator, and the freezing chamber is disposed below the refrigerator.
The schematic diagram of the three-system refrigerator provided by the invention is shown in fig. 1, the refrigerating system of the refrigerator is a circulation loop and comprises a compressor, a condenser, an electric valve, a freezing capillary tube, a freezing evaporator, a freezing fan matched with the freezing evaporator, a refrigerating branch and a temperature-changing branch, wherein the compressor, the condenser, the electric valve, the freezing capillary tube, the freezing evaporator and the freezing fan are arranged in a main path, and the refrigerating branch and the temperature-changing branch are mutually connected in parallel with the freezing capillary tube. The refrigeration branch comprises a refrigeration capillary tube, a refrigeration evaporator and a refrigeration fan matched with the refrigeration evaporator; the temperature change branch comprises a temperature change capillary tube, a temperature change evaporator and a temperature change fan matched with the temperature change evaporator. The refrigerating system of the refrigerator is charged with a refrigerant, such as Freon-12 (CF)2Cl2) The gaseous refrigerant is compressed into high-temperature and high-pressure gas by the compressor and then discharged into the condenser. In a condenserThe refrigerant continuously releases heat to the surrounding space and gradually condenses into high-pressure liquid. The high-pressure liquid flows through the capillary tube, is throttled and depressurized, then slowly flows into the evaporator, is continuously vaporized in the evaporator, absorbs heat to reduce temperature, the vaporized refrigerant is discharged to the compressor to be continuously compressed, and the circulation is repeated and continuously performed, and the heat around the evaporator is conveyed to the condenser to be discharged by means of the change of the state of the refrigerant, so that the aim of refrigeration is fulfilled.
The variable temperature compartment can be used as a refrigerating compartment and a freezing compartment according to different set temperatures. The working state of each compartment is mainly divided into a refrigerating state and a non-refrigerating state, and more specifically, the working state can be divided into a refrigerating state, a refrigerating state and a non-refrigerating state. The compartment evaporator works in a refrigeration state, and the compartment is continuously refrigerated; the compartment evaporator in the non-cooling state stops operating, and the compartment stops cooling. The refrigerator determines the current operation mode according to the set temperature of the temperature-changing chamber and the working state of each chamber, for example, the refrigerator operates in an operation mode in which the temperature-changing chamber is used as a refrigerating chamber and the freezing chamber is in a refrigerating state. And finally, controlling each evaporator fan according to the operation mode of the refrigerator, the temperature of each compartment and the temperature of each evaporator, so that the cold energy produced by the evaporators can be fully utilized, and the refrigeration efficiency of the refrigerator is improved.
In a preferred embodiment of the present application, each capillary tube is further connected to an electric valve, and the operating state of each chamber is determined according to the switching result of the electric valve.
The electric valve can switch the branch of the refrigerant flow direction, the branch of the refrigerant flow direction is different, and the working states of each chamber of the refrigerator are different.
When the electric valve is switched to the freezing branch, the flow direction of the refrigerant is the compressor, the condenser, the electric valve, the freezing capillary tube, the freezing evaporator and the compressor, at the moment, the working state of the freezing chamber of the refrigerator is a refrigerating state, and the refrigerating chamber and the temperature-changing chamber are in a non-refrigerating state.
When the electric valve is switched to the temperature-changing branch, the flow direction of the refrigerant is the compressor, the condenser, the electric valve, the temperature-changing capillary tube, the temperature-changing evaporator, the freezing evaporator and the compressor, at the moment, the working state of the temperature-changing chamber of the refrigerator is a refrigerating state, and the refrigerating chamber and the freezing chamber are in a non-refrigerating state.
When the electric valve is switched to the refrigeration branch, the flow direction of the refrigerant is the compressor, the condenser, the electric valve, the refrigeration capillary tube, the refrigeration evaporator, the freezing evaporator and the compressor, at the moment, the working state of the refrigeration chamber of the refrigerator is a refrigeration state, and the temperature-changing chamber and the freezing chamber are in a non-refrigeration state.
When the refrigerator needs to stop refrigerating integrally, the compressor stops working, the refrigerant does not flow, and the temperature changing chamber, the refrigerating chamber and the freezing chamber are in an uncooled state no matter whether the electric valve is switched to any branch circuit currently.
Therefore, no matter the electric valve of the refrigerator is switched to any branch, the refrigerant can pass through the freezing evaporator, but under different operation modes of the refrigerator, the influence of the refrigerating system on the freezing chamber is different, and the fans of the evaporators are controlled according to different operation modes to achieve the optimal refrigerating effect of the refrigerator.
In order to accurately determine the operation mode of the refrigerator, in a preferred embodiment of the present application, the controller is configured to:
if the set temperature of the temperature-changing chamber is higher than a first preset threshold value and the freezing chamber exits from a refrigerating state, determining that the operation mode is a first preset operation mode;
if the set temperature is higher than the first preset threshold value and the freezing chamber enters a refrigerating state, determining that the operation mode is a second preset operation mode;
if the set temperature is higher than the first preset threshold value and the refrigerating chamber exits from the refrigerating state, determining that the operation mode is a third preset operation mode;
if the set temperature is higher than the first preset threshold value and the temperature-changing chamber exits from the refrigerating state, determining that the operation mode is a fourth preset operation mode;
if the set temperature is lower than a second preset threshold value and the refrigerating chamber is in a refrigerating state, determining that the operation mode is a fifth preset operation mode;
and if the set temperature is lower than a second preset threshold value and the temperature-changing chamber is in a refrigerating state, determining that the operation mode is a sixth preset operation mode.
Specifically, the set temperature of the variable temperature chamber is higher than a first preset threshold value to represent that the variable temperature chamber is used as a refrigerating chamber, and the set temperature of the variable temperature chamber is lower than a second preset threshold value to represent that the variable temperature chamber is used as a freezing chamber. The first preset threshold is greater than or equal to the second preset threshold, and the specific threshold can be adjusted by those skilled in the art according to design requirements. If the first preset threshold is greater than the second preset threshold and the set temperature is between the first preset threshold and the second preset threshold, the operation of the refrigerator can be controlled according to a control mode in the prior art. The technical scheme is within the protection scope of the application.
Each preset operation mode represents the actual operation state of the current refrigerator, specifically represents the temperature state of the temperature-changing chamber and the working state of each chamber (the working state of each branch is the same as that of the corresponding chamber), so that each evaporator fan can be controlled in the subsequent process, and the refrigeration efficiency can be improved.
In order to improve the cooling efficiency of the refrigerator, in a preferred embodiment of the present application, the controller is configured to:
if the operation mode is the first preset operation mode, the second preset operation mode or the sixth preset operation mode, controlling the refrigerating fan according to the temperature of the refrigerating chamber and the temperature of the refrigerating evaporator;
if the operation mode is the third preset operation mode, keeping the refrigerating fan in an operation state, and stopping the refrigerating fan until the temperature of the refrigerating evaporator is not less than the temperature of the refrigerating chamber;
if the operation mode is the fourth preset operation mode, keeping the variable temperature fan in the operation state, and stopping the variable temperature fan until the temperature of the variable temperature evaporator is not less than the temperature of the variable temperature chamber;
and if the operation mode is the fifth preset operation mode, keeping the freezing fan in a stop state.
Specifically, to further explain the concept of the present invention, the following description will be given by taking specific implementation scenarios as examples, when the variable temperature compartment is used as a freezing compartment, the ambient temperature is 25 ℃, and the refrigerator gear is set (freezing-25 ℃, variable temperature-18 ℃, and refrigerated storage 3 ℃) as examples, and when the variable temperature compartment is used as a refrigerating compartment, the ambient temperature is 25 ℃, and the refrigerator gear is set (freezing-25 ℃, variable temperature-5 ℃, and refrigerated storage 3 ℃) as examples.
If the operation mode is the third preset operation mode, the variable-temperature chamber is used as a refrigerating chamber, the refrigerating chamber exits from a refrigerating state, the refrigerating branch stops refrigerating, the refrigerating evaporator stops working, the controller keeps the refrigerating fan in the operating state at the moment, and the refrigerating fan is stopped when the temperature of the refrigerating evaporator is not lower than that of the refrigerating chamber. Under the current operating mode, when cold-stored branch road stops to refrigerate, cold-stored evaporimeter temperature begins to rise, but cold-stored evaporimeter temperature is less than the temperature of cold-stored room all the time, cold-stored evaporimeter at this moment still has the refrigeration effect, so when cold-stored branch road stops to refrigerate, cold-stored fan should postpone to close, utilize surplus cold energy among the cold-stored evaporimeter to continue to cool down for cold-stored indoor food of room, this kind of secondary cooling can make the start time delay of cold-stored room simultaneously, thereby reduced in freezing room refrigeration process, the cold-stored room is strived for the refrigerated condition of start. However, if the refrigerating fan is turned on for a long time, there is still a risk that the cold in the refrigerating chamber flows back to the refrigerating evaporator, so that the refrigerating fan needs to be turned off when the temperature of the refrigerating evaporator is not less than the temperature of the refrigerating chamber.
If the operation mode is the fourth preset operation mode, the variable temperature chamber is used as a refrigerating chamber, the variable temperature chamber exits from a refrigerating state, the variable temperature branch stops refrigerating, the variable temperature evaporator stops working, the controller keeps the variable temperature fan in the operating state at the moment, and the variable temperature fan is stopped when the temperature of the variable temperature evaporator is not lower than that of the variable temperature chamber. In the current operation mode, when the temperature-changing branch stops refrigerating, the temperature of the temperature-changing evaporator begins to rise, but the temperature of the temperature-changing evaporator is always lower than that of the temperature-changing chamber, and the temperature-changing evaporator still has a refrigerating effect at the moment. However, if the variable temperature fan is turned on for too long, there is still a risk that the cold in the variable temperature chamber flows back to the variable temperature evaporator, so that the variable temperature fan needs to be turned off when the temperature of the variable temperature evaporator is not less than the temperature of the variable temperature chamber.
If the operation mode is the fifth preset operation mode, the variable-temperature chamber is used as a freezing chamber, the cold storage chamber is in a refrigerating state, and the controller controls the freezing fan to be kept in a stop state. In the current operation mode, when the refrigeration branch starts to cool, the temperature of the refrigeration evaporator starts to drop, the temperature of the refrigeration compartment drops, but the temperature of the refrigeration evaporator is higher at the moment (about-25 ℃), because the volume of the refrigeration compartment is usually larger and the thermal load is larger, and when the refrigerant flows through the refrigeration evaporator, the refrigerant is almost completely evaporated, so that when the refrigerant flows through the end refrigeration evaporator, the phase-change heat exchange is completely consumed, and the low temperature of the refrigeration evaporator cannot be maintained. At the moment, the temperature of the freezing chamber is-32 ℃ and is lower than the temperature of the freezing evaporator, so that in order to prevent the cold in the freezing chamber from flowing back to the freezing evaporator to cause the temperature of the freezing chamber to rise, when the refrigeration branch starts to refrigerate, the freezing fan cannot be started in the whole process.
If the operation mode is the first preset operation mode, the second preset operation mode or the sixth preset operation mode, the operation of the refrigerating fan is controlled according to the temperature of the refrigerating chamber and the temperature of the refrigerating evaporator, and the surplus cold in the refrigerating evaporator is used for continuously reducing the temperature of the refrigerating chamber or preventing the cold in the refrigerating chamber from flowing back to the refrigerating evaporator.
In order to improve the cooling efficiency of the refrigerator, in a preferred embodiment of the present application, the controller is further specifically configured to:
if the operation mode is the first preset operation mode, keeping the refrigerating fan in an operation state, and stopping the refrigerating fan until the temperature of the refrigerating evaporator is not less than the temperature of the refrigerating chamber;
if the operation mode is the second preset operation mode, keeping the freezing fan in a stop state, and starting the freezing fan until the temperature of the freezing evaporator is not more than the temperature of the freezing chamber;
if the operation mode is the sixth preset operation mode and the temperature of the freezing evaporator is lower than that of the freezing chamber, starting the freezing fan;
and if the operation mode is the sixth preset operation mode and the temperature of the freezing evaporator is not less than the temperature of the freezing chamber, the freezing fan is stopped.
Specifically, if the operation mode is the first preset operation mode, the variable-temperature chamber serves as a refrigerating chamber, the freezing chamber reaches the stop temperature and exits from the refrigerating state, the freezing evaporator stops working, and the controller keeps the freezing fan in the operating state until the temperature of the freezing evaporator is not lower than the temperature of the freezing chamber. In the current operation mode, when the refrigeration of the freezing chamber is stopped, the electric valve is switched to the refrigeration or temperature change branch, the temperature of the freezing evaporator begins to rise, at the moment, the temperature of the freezing evaporator is-32.66 ℃, the temperature of the freezing chamber is-26.87 ℃, and the freezing evaporator can slowly reach the temperature in the freezing chamber only in 3-5min, so that when the refrigeration of the freezing branch is stopped, the freezing fan is controlled to continuously work, and the freezing evaporator and the residual cold quantity in the space of the freezing evaporator are fully utilized for further cooling the freezing chamber. Meanwhile, the problem that the temperature of the freezing chamber rises due to shutdown and fluctuates greatly, so that food is not fresh is solved. However, in order to avoid that the starting time of the refrigerating fan is too long, the cold in the refrigerating chamber flows back to the refrigerating evaporator through the air circulation, and when the temperature of the refrigerating evaporator is not less than the temperature of the refrigerating chamber, the refrigerating fan is controlled to stop rotating.
If the operation mode is the second preset operation mode, the variable temperature chamber is used as a refrigerating chamber, the freezing chamber enters a refrigerating state, the freezing evaporator starts to work, the controller keeps the freezing fan in a stop state at the moment, and the freezing fan is started until the temperature of the freezing evaporator is not higher than the temperature of the freezing chamber. In the current operation mode, when the freezing chamber starts to refrigerate, the temperature of the freezing evaporator begins to drop, the temperature (-15.72 ℃) of the freezing evaporator is higher than the temperature (-27 ℃) of the freezing chamber in the first 1-4min, if the freezing fan is started immediately in the period, the temperature of the freezing chamber can rise, the temperature of the freezing chamber is not good for temperature rise of the freezing chamber, meanwhile, the temperature fluctuation of the freezing chamber is large, food preservation in the chamber is not good for keeping fresh, therefore, the temperature of the freezing evaporator should be reduced firstly, when the temperature of the freezing evaporator is not higher than the temperature of the freezing chamber, the freezing fan is controlled to be started, and the freezing chamber starts to refrigerate.
If the operation mode is the sixth preset operation mode, the variable temperature chamber is used as a freezing chamber, the variable temperature chamber is in a refrigerating state, and the controller controls the freezing fan to be started when the temperature of the freezing evaporator is lower than that of the freezing chamber. Under the current operation mode, when the refrigeration of the freezing branch is just finished and the temperature change branch starts to refrigerate, the temperature of the freezing evaporator is lower than that of the freezing chamber, the freezing fan is controlled to be started, and the excess cold quantity in the freezing evaporator is fully utilized.
If the operation mode is the sixth preset operation mode, the controller controls the operation stop of the refrigerating fan when the temperature of the refrigerating evaporator is not less than the temperature of the refrigerating chamber. The system is shut down after the refrigeration of the freezing branch, then the temperature change branch performs refrigeration, but the temperature of the freezing evaporator (about minus 31 ℃) is always higher than the temperature of the freezing chamber (about minus 32.5 ℃), and in order to prevent cold air in the freezing chamber from flowing back to the evaporator, the temperature in the freezing chamber is increased, and the freezing fan cannot be started.
