Detailed Description
The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Referring to fig. 1, an embodiment of the present invention provides a method for controlling a refrigerator, including: confirming that the refrigerator starts a defrosting process;
acquiring the temperature of a first refrigerating device in a freezing chamber and the temperature of a second refrigerating device in a refrigerating chamber of the refrigerator, if the temperature of the first refrigerating device is higher than the temperature of the second refrigerating device, leading air in a compressor bin into the freezing chamber and/or the refrigerating chamber for heat exchange, and discharging the air in a box body of the refrigerator into the box body of the refrigerator.
The control method in the embodiment of the invention is preferably used for a multi-system refrigerator. The freezing chamber can be one or a plurality of freezing chambers; one or more refrigerating chambers can be provided; the number of the compressor bins can be one or more. The refrigerating chamber can be a conventional refrigerating chamber at present, and can also be a storage chamber with other functions.
When a plurality of freezing chambers and a plurality of refrigerating chambers are arranged, a first refrigerating device is arranged in at least one freezing chamber, and a second refrigerating device is arranged in at least one refrigerating chamber. The following description will be given taking as an example a conventional structure in which a freezing chamber and a refrigerating chamber are provided, the freezing chamber being located below the refrigerating chamber, and a compressor compartment being located below the freezing chamber. The refrigerator comprises a refrigerator body, a first refrigerating device, a second refrigerating device, a door and a refrigerator door, wherein the first refrigerating device and the second refrigerating device are arranged on the same side of the refrigerator body and are arranged close to the back of the refrigerator body; and the second cooling device is located above the first cooling device.
When the refrigerator does not need defrosting, the refrigerator can normally run. When the refrigerator needs defrosting, when the temperature of the first refrigerating device is higher than that of the second refrigerating device, the air in the compressor bin is guided into the freezing chamber and/or the refrigerating chamber; the air introduced into the freezing chamber and/or the refrigerating chamber is diffused in the freezing chamber and/or the refrigerating chamber, and particularly exchanges heat with a refrigerating device or a frosted part in the freezing chamber and/or the refrigerating chamber, so that the aim of assisting defrosting is fulfilled.
The method for confirming whether the refrigerator needs defrosting or not can be realized by a conventional judgment mode, and an improved scheme can be adopted as long as the refrigerator can be confirmed to start defrosting or enter the defrosting process.
Because the compressor operation in-process of refrigerator can produce the heat, with the hot-air in the compressor storehouse according to the difference of freezer and the indoor relative temperature of freezer, the leading-in air in freezer and/or the freezer of adjustment, make the hot-air that produces in the compressor storehouse be used for defrosting, can improve the utilization efficiency of energy, simultaneously, also be favorable to the heat emission in the compressor storehouse.
The air introduced into the freezing chamber and/or the refrigerating chamber is discharged out of the refrigerator body through an outlet provided in the refrigerator body after exchanging heat with the refrigerating device or the frosted portion in the freezing chamber and/or the refrigerating chamber. The number of the outlets for discharging the gas in the box body can be one or more. It can be understood that, when the auxiliary defrosting process is finished, the outlet of the refrigerator body for introducing or discharging gas is closed, so as to avoid affecting the refrigerating efficiency of the refrigerator.
The air introduced into the freezing chamber and/or the refrigerating chamber can be diffused in the storage space of the freezing chamber and/or the refrigerating chamber or can be diffused only in the refrigerating device accommodating chamber where the refrigerating device in the freezing chamber and/or the refrigerating chamber is located and isolated from the corresponding storage space so as to exchange heat with the corresponding refrigerating device, and the purpose of assisting defrosting is achieved. Preferably only in the refrigeration device receiving chamber or heat exchange chamber in which the respective refrigeration device is located.
The temperature difference change of the first refrigerating device and the second refrigerating device is different, the mode of introducing air into the freezing chamber or the refrigerating chamber is different, the auxiliary defrosting mode in the freezing chamber and the refrigerating chamber is reasonably controlled according to the temperature change of the first refrigerating device and the second refrigerating device, and the energy utilization efficiency can be further improved. Specifically, the firstTemperature T of refrigerating devicebAnd temperature T of the second cooling deviceaThe temperature of the inner or outer surface of the refrigeration device or the temperature of the air in the chamber in which the refrigeration device is located.
The air in the compressor bin is led into the freezing chamber and/or the refrigerating chamber, and is discharged out of the refrigerator body after exchanging heat with refrigerating devices or frosted parts in the freezing chamber and/or the refrigerating chamber, so that the influence on the refrigerating effect of the refrigerator caused by the fact that the air with relatively high temperature stays in the freezing chamber and/or the refrigerating chamber for a long time is avoided.
For a more concise expression, the temperature T of the second cooling device isaHigher than the temperature T of the first cooling devicebThe air introduction mode when it is referred to as the first operation mode; the temperature T of the first refrigerating devicebHigher than temperature T of the second cooling deviceaThe air introduction mode of time is referred to as a second operation mode.
In a specific embodiment, if the temperature of the second refrigerating device is higher than that of the first refrigerating device, the air in the compressor bin is introduced into the freezing chamber for heat exchange, and the air after heat exchange is discharged out of the refrigerator body of the refrigerator until the temperature of the first refrigerating device is higher than that of the second refrigerating device. On the basis of the above embodiments, this embodiment specifically describes a control method when the temperature of the second cooling device is higher than the temperature of the first cooling device.
When the temperature of the second refrigerating device is higher than that of the first refrigerating device, the temperature of the first refrigerating device in the freezing chamber is relatively low, air in the compressor bin is guided into the freezing chamber, the air with the high temperature in the compressor bin can exchange heat with the first refrigerating device in the freezing chamber or a frosted part, the air in the freezing chamber is discharged out of the refrigerator body, and the defrosting efficiency can be improved until the temperature of the first refrigerating device is higher than that of the second refrigerating device.
In one embodiment, if the temperature T of the second cooling device is lower than the temperature T of the first cooling deviceaHigher than the temperature T of the first cooling devicebIntroducing the air outside the refrigerator body into the refrigerating chamber for heat exchange, and discharging the air in the refrigerating chamber out of the refrigerator body until the first refrigerationTemperature T of the devicebHigher than temperature T of the second cooling devicea. On the basis of the above embodiments, the present embodiment specifically describes the temperature T of the second cooling deviceaHigher than the temperature T of the first cooling devicebA method of controlling the timing.
When the temperature T of the first cooling devicebLower than the temperature T of the second cooling deviceaWhen the refrigerator is used, the temperature in the freezing chamber or the chamber where the first refrigerating device is located in the freezing chamber is relatively low, at the moment, the air in the compressor bin is directly led into the freezing chamber and only led into the freezing chamber, and the air outside the refrigerator box is led into the refrigerating chamber, so that the air with high temperature in the compressor bin can concentrate on heat exchange of the refrigerating device in the freezing chamber or a frosted part, and the defrosting efficiency can be improved. The gas after heat exchange is discharged out of the refrigerator body from an outlet of the freezing chamber in time, so that the influence on the refrigerating efficiency of the freezing chamber due to the long-time retention of the gas with higher temperature is avoided.
Meanwhile, for the second refrigerating device in the refrigerating chamber with relatively high temperature, the air in the external environment is led into the refrigerating chamber from the outside of the refrigerator body so as to exchange heat with the second refrigerating device in the refrigerating chamber or a frosted part. The gas after heat exchange is discharged out of the refrigerator body of the refrigerator from an outlet of the refrigerating chamber in time, so that the influence on the refrigerating efficiency of the refrigerating chamber due to the long-time stay of the gas with higher temperature is avoided.
In the auxiliary defrosting process, air is introduced into the freezing chamber from the compressor bin, air is introduced into the refrigerating chamber from the outside of the refrigerating chamber, and the heat-exchanged gas is discharged out of the refrigerator body from the outlet of the freezing chamber or the refrigerating chamber in time, so that the purposes of air exchange and odor removal in the refrigerator can be achieved while defrosting.
In one embodiment, if the temperature T of the first cooling device is lower than the temperature T of the second cooling devicebHigher than temperature T of the second cooling deviceaThe air in the compressor chamber is introduced into the freezing chamber, and then introduced into the refrigerating chamber from the freezing chamber, and the air in the refrigerating chamber is discharged out of the refrigerator body. On the basis of the above embodiments, the present embodiment specifically describes the temperature T of the first cooling devicebHigher than the second refrigerating deviceTemperature T ofaA method of controlling the timing.
When the temperature T of the first cooling devicebHigher than temperature T of the second cooling deviceaTemperature T of the first refrigerating device in the freezer compartmentbAnd when the temperature is relatively high, the air in the compressor bin is guided into the freezing chamber, and the temperature is still relatively high after the air exchanges heat with the first refrigerating device or the frosted part. At this time, the air in the freezing chamber is not directly discharged out of the refrigerator, and the air in the freezing chamber can be introduced into the refrigerating chamber to further exchange heat with the second refrigerating device or the frosted part in the refrigerating chamber, so that the heat of the compressor chamber and the first refrigerating device in the freezing chamber is fully utilized.
The gas introduced from the freezing chamber into the refrigerating chamber is discharged from an outlet of the refrigerating chamber into the refrigerator. And meanwhile, the air exchange and odor removal effects are achieved while the defrosting is assisted. Under the condition, the air outside the refrigerator can not be led into the freezing chamber and/or the refrigerating chamber from the outside of the refrigerator, and the air in the cabin of the compressor is directly used for assisting defrosting.
In a specific embodiment, if the temperature of the first refrigerating device is higher than that of the second refrigerating device, the air in the compressor bin is introduced into the refrigerating chamber for heat exchange, and the air in the refrigerating chamber is discharged out of the refrigerator body of the refrigerator; the air in the compressor compartment is introduced into the freezer compartment and the air in the freezer compartment is discharged out of the cabinet of the refrigerator, or the air in the compressor compartment is introduced into the freezer compartment and the air in the freezer compartment is introduced into the refrigerator compartment and the air in the refrigerator compartment is discharged out of the cabinet of the refrigerator. On the basis of the above embodiments, the present embodiment specifically describes the temperature T of the first cooling devicebHigher than temperature T of the second cooling deviceaAnother control method of the time.
Temperature T of the first cooling devicebHigher than temperature T of the second cooling deviceaWhen the temperature T of the second refrigerating device in the refrigerating chamber is higher than the temperature T of the first refrigerating device in the refrigerating chamberaThe temperature difference between the air in the compressor bin and a second refrigerating device in the refrigerating chamber is large; at this time, the air in the compressor compartment is directly introduced into the refrigerating chamber, and the air in the compressor compartment and the refrigerating chamber are secondarily controlledThe heat exchange efficiency of the cold device or the frosting part is higher, and the heat of the compressor bin can be more efficiently utilized. Under the condition, air outside the refrigerator can not be led into the refrigerating chamber from the outside of the refrigerator, and air in the compressor bin is directly used for assisting defrosting.
Specifically, air in the compressor compartment is introduced into the freezer compartment and the refrigerator compartment, respectively; in the freezing chamber, after the air introduced into the freezing chamber by the compressor bin exchanges heat with the first refrigerating device or a frosted part, the air is discharged out of the refrigerator from an outlet of the freezing chamber, or the air introduced into the freezing chamber after exchanging heat is introduced into the refrigerating chamber again, exchanges heat with the second refrigerating device or the frosted part in the refrigerating chamber and then is discharged out of the refrigerator from an outlet of the refrigerating chamber; the air directly led into the refrigerating chamber from the compressor bin exchanges heat with the second refrigerating device or the frosted part, and then is discharged out of the refrigerator from an outlet of the refrigerating chamber.
In one specific embodiment, air outside the refrigerator body is introduced into the refrigerating chamber for heat exchange, and air in the refrigerating chamber is discharged out of the refrigerator body. On the basis of the above embodiments, the present embodiment specifically describes the temperature T of the first cooling devicebHigher than temperature T of the second cooling deviceaYet another preferred embodiment of the invention.
In particular, at the temperature T of the first cooling devicebHigher than temperature T of the second cooling deviceaUnder the condition of (1), introducing air in the compressor bin into the freezing chamber, exchanging heat with a first refrigerating device or a frosted part in the freezing chamber, and then introducing the air into the refrigerating chamber; meanwhile, the air outside the refrigerator can be introduced into the refrigerating chamber, exchanges heat with the second refrigerating device or a frosted part in the refrigerating chamber together with the air introduced into the refrigerating chamber through the freezing chamber, and then is discharged out of the refrigerator body of the refrigerator through an outlet of the refrigerating chamber.
Also, at the temperature T of the first cooling devicebHigher than temperature T of the second cooling deviceaUnder the condition of (1), the air in the compressor bin is respectively led into the freezing chamber and the refrigerating chamber, and the air led into the freezing chamber from the compressor bin exchanges heat with the first refrigerating device or a frosted part and then is directly led into the freezing chamberAn outlet discharges the refrigerator body of the refrigerator, or the air introduced into the freezing chamber exchanges heat with the first refrigerating device or the frosted part and then is introduced into the refrigerating chamber; in the refrigerating chamber, the air introduced from the compressor bin and the outside of the refrigerator body exchanges heat with the second refrigerating device or the frosted part, or the air introduced from the compressor bin and the outside of the refrigerator body into the refrigerating chamber and the air introduced from the freezing chamber into the refrigerating chamber exchange heat with the second refrigerating device or the frosted part and then are discharged out of the refrigerator body from an outlet of the refrigerating chamber.
Under the condition of more frosting or relatively low temperature, the compressor bin and the air outside the refrigerator carry out heat exchange on the first refrigerating device and the second refrigerating device or a frosting part together, so that the heat exchange efficiency is improved, and the energy consumption is reduced.
In a specific embodiment, if the process of introducing the air in the compressor chamber into the freezing chamber and/or the refrigerating chamber and discharging the air out of the refrigerator body of the refrigerator from the outlet of the refrigerator body is performed for a time period greater than a first set time t, the introduction of the air into the freezing chamber and/or the refrigerating chamber is stopped, the heater is turned on to heat the first refrigerating device and/or the second refrigerating device until defrosting is finished, or the heater is turned on to heat the refrigerating device in the freezing chamber and the operation time is greater than a second set time t1The heater is turned off and the compressor bin begins to empty.
The gas is introduced into the freezing chamber and/or the refrigerating chamber until defrosting is finished. On the basis of the above embodiments, the present embodiment specifically describes the defrosting process.
In particular, when the temperature T of the first cooling devicebHigher than temperature T of the second cooling deviceaAt least four different defrosting actions can be respectively adopted under the condition of (1). The four different defrosting actions can be respectively as follows: the auxiliary defrosting operation of leading the air in the compressor bin into the freezing chamber and then leading the air in the compressor bin into the refrigerating chamber is adopted, or the auxiliary defrosting operation of leading the air in the compressor bin into the freezing chamber and the refrigerating chamber respectively is adopted, or the air in the compressor bin is led into the freezing chamber and then is led into the refrigerating chamber from the freezing chamber, and simultaneously, the air outside the refrigerator body is led into the refrigerating chamber from the freezing chamberThe auxiliary defrosting action of introducing air into the refrigerating chamber or the auxiliary defrosting action of introducing air outside the refrigerator body into the refrigerating chamber while introducing air in the compressor chamber into the freezing chamber and the refrigerating chamber respectively is adopted.
When any one of the four different auxiliary defrosting actions is adopted, after the execution time of the auxiliary defrosting action exceeds a first set time t, the introduction of air in the compressor bin or air outside the refrigerator body into the freezing chamber and/or the refrigerating chamber is stopped, and the heater is started to heat the first refrigerating device and/or the second refrigerating device until the defrosting process is finished. The first set time t for the auxiliary defrosting action to be executed may be preset, or may be dynamically adjusted according to the temperature of the first cooling device and/or the second cooling device.
Before the heater is used for heating the first refrigerating device and/or the second refrigerating device, air in the compressor bin or air in the compressor bin and air outside the refrigerator body are firstly used for carrying out auxiliary defrosting actions on the first refrigerating device, the second refrigerating device or frosted parts, so that the energy consumption of the heater can be reduced, heat generated in the operation process of the refrigerator can be effectively utilized, the energy consumption is reduced, and the heat utilization efficiency is improved.
