Detailed Description
The present invention first provides a control method of a refrigerator, and fig. 1 is a schematic structural view of a refrigerator according to an embodiment of the present invention. The refrigerator 1 of the present invention includes a storage compartment 11 for storing articles and a storage device 20 disposed in the storage compartment 11, and the storage device 20 has a drying mode and a moisturizing mode in which preset humidity ranges are different. That is, the preset humidity range of the storage device 20 in the dry mode is different from the preset humidity range thereof in the wet mode, and specifically, the preset humidity range of the storage device 20 in the dry mode is lower than the preset humidity range thereof in the wet mode. When the storage device 20 is set to the dry mode, the humidity in the storage device is low, and the storage device can be used for storing valuables, dry goods and the like; when the storage device 20 is set to the moisture retention mode, the humidity in the storage device is high, and the storage device can be used for storing fruits and vegetables.
Further, the storage device 20 includes a supply air port 21 for supplying air thereinto and a return air port 22 for allowing air inside thereof to flow out. The refrigerator 1 further includes an evaporator 30 for providing a cooling air flow and a supply air damper 40 provided on an air flow path between the evaporator 30 and the supply air outlet 21.
The refrigerator control method of the present invention is proposed based on the refrigerator 1 having the above-described structure. The control method of the invention comprises the following steps:
when the storage device 20 is in the drying mode, acquiring humidity in the storage device 20;
judging whether the refrigerator 1 is in a refrigerating state or not when the humidity in the storage device 20 is higher than a first preset humidity threshold value;
if the refrigerator 1 is in a cooling state, the air supply damper 40 is directly opened to open the airflow path between the evaporator 30 and the air supply outlet 21, so as to allow the cooling airflow generated by the evaporator 30 to flow into the storage device 20;
if the refrigerator 1 is in the non-cooling state, cooling is forcibly started, and the air supply damper 40 is opened after a preset condition is satisfied, so as to open the airflow path between the evaporator 30 and the air supply outlet 21, thereby allowing the cooling airflow generated by the evaporator 30 to flow into the storage device 20.
When the storage device 20 is in the dry mode and the humidity in the storage device 20 is high, the air supply damper 40 is not directly opened, but whether the refrigerator 1 is in the refrigeration state is determined, and then different operations are respectively executed according to whether the refrigerator 1 is refrigerated or not. When the refrigerator 1 is in a cooling state, it is stated that the refrigerant is introduced into the evaporator 30, the temperature of the evaporator 30 is low, the temperature and the humidity of the cooling air flow formed after the air flow passes through the evaporator 30 are low, and at this time, the air supply damper 40 can be directly opened to allow the cooling air flow to immediately flow into the storage device 20, so that a low-humidity storage environment is quickly formed in the storage device 20. When the refrigerator 1 is in the non-cooling state, which means that no refrigerant flows through the evaporator 30, it is necessary to forcibly start cooling so that the refrigerant flows through the evaporator 30, thereby lowering the temperature of the evaporator 30, and lowering the humidity of the airflow after flowing through the evaporator 30. The air supply air door 40 is opened after the preset condition is met, the opening time of the air supply air door 40 is equivalently delayed, the humidity of the cooling air flow formed at the moment is low enough, the humidity in the storage device 20 can be effectively reduced, the phenomenon that the humidity in the storage device 20 is temporarily increased can not occur, the better preservation quality of dry goods is ensured, and the dry goods is prevented from being damped and deteriorated.
In some embodiments, the control method of the present invention further comprises: when the storage device 20 is in the moisture retention mode, the air supply damper 40 is closed to block the airflow path between the evaporator 30 and the air supply outlet 21, thereby preventing the cooling airflow generated by the evaporator 30 from flowing into the storage device 20. Fruits and vegetables stored in the storage device 20 can volatilize a large amount of water, so that the humidity in the storage device 20 is improved, and the storage quality of the fruits and vegetables is ensured.
Further, the storage device 20 further comprises a moisture permeable film 23 allowing moisture inside the storage device to permeate outwards, when the humidity inside the storage device 20 is too high, too much moisture can permeate outwards through the moisture permeable film 23, and the phenomenon of condensation caused by too high humidity inside the storage device 20 is avoided.
Fig. 2 is a schematic flowchart of a control method of a refrigerator according to one embodiment of the present invention. The control method of the invention specifically comprises the following steps:
step S10, acquiring a functional mode of the storage device 20;
step S20, judging whether the functional mode of the storage device 20 is a drying mode or a moisturizing mode; if the mode is the moisture retention mode, turning to the step S30, if the mode is the drying mode, turning to the step S40;
step S30, closing the air supply damper 40 to block the airflow path between the evaporator 30 and the air supply outlet 21, thereby preventing the cooling airflow generated by the evaporator 30 from flowing into the storage device 20;
step S40, acquiring humidity in the storage device 20;
step S50, judging whether the humidity in the storage device 20 is higher than a first preset humidity threshold value; if yes, go to step S70, if no, go to step S60;
step S60, keeping the air supply damper 40 closed;
step S70, judging whether the refrigerator 1 is in a refrigerating state or not; if yes, go to step S80, otherwise go to step S90;
step S80, directly opening the air supply damper 40 to conduct the airflow path between the evaporator 30 and the air supply outlet 21, so as to allow the cooling airflow generated by the evaporator 30 to flow into the storage device 20;
in step S90, cooling is forcibly started, and the air supply damper 40 is opened after a preset condition is satisfied, so as to open the airflow path between the evaporator 30 and the air supply outlet 21, thereby allowing the cooling airflow generated by the evaporator 30 to flow into the storage device 20.
In some embodiments, the preset condition is that the refrigerator 1 forcibly starts cooling for a first preset time. That is, the opening of the air supply damper 40 can be controlled by delaying the opening time of the air supply damper 40, and other parameters do not need to be acquired or complicated analysis processing is carried out on the parameters, so that the control logic of the refrigerator is simplified. In these embodiments, referring to the schematic flowchart of fig. 3 illustrating the steps of forcibly starting cooling and reopening the air supply damper after the preset condition is met according to an embodiment of the present invention, the steps of forcibly starting cooling and reopening the air supply damper after the preset condition is met may specifically include:
step S91, starting cooling so that the refrigerant flows through the evaporator 30;
step S92, judging whether the refrigerating starting time reaches a first preset time; if yes, turning to step S93, otherwise, returning to continue judging;
in step S93, the air supply damper 40 is opened to open the airflow path between the evaporator 30 and the air supply opening 21, thereby allowing the cooling airflow generated by the evaporator 30 to flow into the storage device 20.
Specifically, after the refrigerator is forcibly started for a first preset time period, the temperature of the evaporator 30 is reduced sufficiently, the humidity of the cooling air flow formed after flowing through the evaporator 30 is also sufficiently low, and at this time, the air supply damper 40 is opened, and the cooling air flow flows into the storage device 20, so that the lower humidity in the storage device 20 is always kept, and the storage of dry goods is facilitated.
Further, the first preset time period may be any time period value within a range of 3 to 5min. For example, the first preset time period may be 3min, 3.5min, 4min, 4.5min, or 5min. Specifically, if the first predetermined time period is too short, for example, less than 3min, the temperature of the evaporator 30 is not decreased, and the humidity of the cooling air flow formed after flowing through the evaporator 30 is still high, so that the humidity in the storage device 20 cannot be effectively decreased. If the first predetermined time period is too long, for example, more than 5min, the temperature of the evaporator 30 is already reduced, which not only results in energy waste, but also may affect the temperature in the storage compartment 11.
It is understood that the first preset time period can be selected according to the cooling speed of the refrigerator 1, and the first preset time period can be different for different cooling systems.
In other embodiments, the predetermined condition may be that the relative humidity value of the cooling airflow generated by the evaporator 30 relative to the environment inside the storage device 20 is lower than the second predetermined humidity threshold. That is, the opening of supply damper 40 may be controlled directly by the relative humidity of the cooling air flow.
The applicant has appreciated that the root cause of the delayed opening of the supply damper 40 is that the cooling air flow is not as humid as it is immediately after cooling is initiated. Therefore, the opening of the air supply air door 40 is controlled directly according to the comparison between the relative humidity value of the cooling air flow and the second preset humidity threshold value, the actual situation is better met, and the control precision is higher.
Further, the relative humidity value of the cooling air flow may be obtained by:
acquiring an absolute humidity value of a cooling airflow on an airflow flow path between the evaporator 30 and the air supply opening 21 and a temperature value in the storage device 20; and
and searching the relative humidity value of the absolute humidity value at the temperature value in a preset air temperature and humidity comparison table or calculating the relative humidity value of the absolute humidity value at the temperature value according to a preset calculation formula.
The invention obtains the absolute humidity of the cooling air flow and the temperature in the storage device 20, and obtains the relative humidity value of the cooling air flow in the temperature environment in the storage device 20 by means of table look-up or calculation, so that the cost is low.
Specifically, referring to the schematic flowchart of fig. 4 illustrating the steps of forcibly starting cooling and reopening the air supply damper after a preset condition is met according to another embodiment of the present invention, the steps of forcibly starting cooling and reopening the air supply damper after a preset condition is met may specifically include:
step S91', starting cooling so that the refrigerant flows through the evaporator 30;
step S92' of obtaining an absolute humidity value of the cooling airflow on the airflow flow path between the evaporator 30 and the air blowing port 21, and a temperature value inside the storage device 20;
step S93', searching a relative humidity value of the absolute humidity value at the temperature value in a preset air temperature and humidity comparison table, or calculating the relative humidity value of the absolute humidity value at the temperature value according to a preset calculation formula;
step S94', judging whether the relative humidity value is lower than a second preset humidity threshold value; if yes, go to step S95'; if not, returning to step S92' to obtain the absolute humidity value of the cooling airflow on the airflow path between the evaporator 30 and the air blowing port 21 and the temperature value in the storage device 20 again;
step S95', the air supply damper 40 is opened to open the airflow path between the evaporator 30 and the air supply opening 21, thereby allowing the cooling airflow generated by the evaporator 30 to flow into the storage device 20.
In still other embodiments, the preset condition may be that the temperature of the cooling air flow on the air flow path between the evaporator 30 and the air blowing opening 21 is lower than a preset temperature threshold. That is, the opening of supply damper 40 may be controlled directly in accordance with the temperature of the cooling air flow.
Applicants have recognized that the temperature and humidity of the airflow decreases as it flows through the evaporator 30, and thus, the humidity of the cooled airflow can be indirectly determined by the temperature of the cooled airflow. Moreover, the temperature of the cooling air flow is directly obtained by a temperature sensing device such as a temperature sensing head, and the cost of the temperature sensing head is much lower than that of a device for obtaining the humidity of the air flow. Therefore, the invention controls the opening of the air supply damper 40 directly according to the comparison between the temperature of the cooling air flow and the preset temperature threshold value, which not only meets the actual condition, but also effectively controls the cost increase of the refrigerator 1.
Specifically, referring to the schematic flowchart of fig. 5 illustrating the steps of forcibly starting cooling and reopening the air supply damper after the preset conditions are met according to another embodiment of the present invention, the steps of forcibly starting cooling and reopening the air supply damper after the preset conditions are met may specifically include:
step S91 ″, starting cooling so that the refrigerant flows through the evaporator 30;
step S92 ″ of acquiring a temperature of the cooling airflow on the airflow flow path between the evaporator 30 and the blower port 21;
step S93', judging whether the temperature of the cooling air flow is lower than a preset temperature threshold value; if yes, go to step S94'; if not, returning to step S92 ″ to acquire the temperature of the cooling airflow on the airflow flow path between the evaporator 30 and the blower port 21 again;
step S94 ″, the air supply damper 40 is opened to open the airflow path between the evaporator 30 and the air supply opening 21, thereby allowing the cooling airflow generated by the evaporator 30 to flow into the storage device 20.
Further, the preset temperature threshold is less than-5 ℃. When the temperature of the cooling air flow is lower than-5 ℃, the humidity of the cooling air flow is correspondingly lower, and the requirement of the storage device 20 is met.
The applicant has appreciated that when the refrigerator 1 is forcibly activated to cool, cooling may not be required in the compartment 11, and that the delivery of a cooling air flow into the compartment 11 may result in the temperature in the compartment 11 being too low to damage the articles resting directly in the compartment 11.
For this purpose, in some embodiments, the air supply opening of the storage compartment 11 may be provided with a compartment air supply damper. In these embodiments, the control method of the present invention further includes:
when the refrigerator starts refrigeration forcibly, the temperature in the storage chamber 11 is obtained;
when the temperature in the storage chamber 11 is higher than the set temperature, the chamber air supply damper is opened to allow cooling airflow to enter the storage chamber 11; when the temperature in the storage compartment 11 is lower than the set temperature, the compartment air supply damper is closed to prevent the cooling air flow from entering the storage compartment 11.
Thus, the humidity adjustment operation of the storage device 20 can be prevented from adversely affecting the temperature in the storage compartment 11 by controlling the opening and closing of the compartment air supply damper.
The applicant recognizes that the prior art generally prevents the cooling air flow from continuously entering the storage device 20 by closing the air supply damper, but neglects the air return opening of the storage device 20, the air return opening of the storage device 20 is directly exposed to the storage compartment 11, and there is a case that the air return of the storage compartment 11 enters the storage device 20 through the air return opening of the storage device 20 to affect the temperature and humidity inside the storage device 20.
To this end, in some embodiments, the storage device 20 further includes a return air damper 24 disposed at the return air opening 22, and the return air damper 24 is configured to be opened and closed in synchronization with the supply air damper 40. That is, the return air damper 24 is configured to open in synchronization with the supply air damper 40 to allow the flow of return air inside the storage device 20 to flow toward the evaporator 30, and to close in synchronization with the supply air damper 40 to prevent the flow of air into and out of the storage device 20.
When the storage device 20 is switched to the dry mode and a certain condition is satisfied, the supply air door 40 and the return air door 24 can be controlled to open to allow the cooling air flow generated by the evaporator 30 to flow into the storage device 20, and the original air in the storage device 20 returns to the evaporator 30 through the return air inlet 22 and the return air duct of the storage compartment 11, so as to replace the air in the storage device 20. Since moisture in the airflow is condensed on the evaporator 30 when the airflow passes through the evaporator 30 with a low temperature, so that the temperature and the humidity of the formed cooling airflow are low, a dry storage space with low temperature and low humidity can be formed in the storage device 20 after the cooling airflow replaces the air in the storage device 20. When the humidity in the storage device 20 is reduced to a preset humidity threshold value corresponding to the drying mode, the supply air damper 40 and the return air damper 24 can be closed in a controlled manner. At this time, even if the return air flows through the return air duct of the storage compartment 11 and no matter whether negative pressure is formed in the storage device 20, the return air duct of the storage compartment and the air flow in the storage compartment 11 do not flow into the storage device 20 under the blocking of the return air damper 24, and the humidity in the storage device 20 is not affected.
Therefore, the dry and wet adjustable storage space is formed in the storage device 20 by arranging the air supply air door 40 and the air return air door 24 and controlling the opening and closing of the air supply air door 40 and the air return air door 24, the humidity of the storage space is not influenced by the storage chamber 11, and the storage quality of articles in the storage device 20 is improved.
The invention also provides a refrigerator, and fig. 6 is a schematic structural block diagram of the refrigerator according to one embodiment of the invention. Referring to fig. 1 and 6, a refrigerator 1 of the present invention includes a storage compartment 11 for storing articles and a storage device 20 disposed in the storage compartment 11, the storage device 20 having a drying mode and a moisturizing mode different in preset humidity range and including a blowing port 21 and a return air port 22.
Further, the refrigerator 1 further includes a supply air damper 40, a humidity sensor 50, and a control device 60. The air supply damper 40 is provided in the airflow path between the evaporator 30 and the air supply outlet 21. The humidity sensor 50 is used for acquiring humidity in the storage device 20. Specifically, the humidity sensor 50 may be disposed in the storage device 20 and electrically connected to the control device 60. The control device 60 comprises a processor 61 and a memory 62, wherein a machine-executable program 63 is stored in the memory 62, and the machine-executable program 63 is used for implementing the control method according to any of the above embodiments when executed by the processor 61.
Specifically, the number of the article storage devices 20 may be one, two, or more than two, and when the number of the article storage devices 20 is two, the two article storage devices 20 are arranged side by side in the lateral direction in the cabinet of the refrigerator 1.
The refrigerator 1 of the present application is a refrigerator in a broad sense, and includes not only a so-called refrigerator in a narrow sense but also a storage device having a refrigerating, freezing or other storage function, for example, a refrigerator, a freezer, and the like.
It will also be understood by those skilled in the art that, unless otherwise specified, all references to humidity herein are relative humidity.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
