Referring to fig. 1 and 2, an embodiment of the present application provides a method and an apparatus for controlling a dehumidifier, which are applied to a dehumidifier 10. The dehumidifier 10 includes a water tank 110, a water pump 120, a compressor 130, a sensor 140, a fan (not shown), a condenser (not shown), an evaporator (not shown), a restrictor (not shown) and the like, it is understood that the heat exchange medium flows to the condenser in a high-temperature and high-pressure state under the compression action of the compressor 130, the high-temperature and high-pressure heat exchange medium is cooled under the action of the condenser to form low-temperature and high-pressure liquid, the low-temperature and low-pressure liquid is formed by the heat exchange medium through the restrictor, the heat exchange medium then flows to the evaporator, the low-temperature and low-pressure liquid heat exchange medium performs heat transfer with air introduced by the fan, namely absorbs heat through the heat exchange medium to condense moisture in the air, thereby achieving the dehumidification purpose, and the heat exchange medium is converted into low-pressure gas by the liquid and flows to the compressor 130 again. The heat exchange medium may be, but is not limited to, a refrigerant.
In the present embodiment, the sensor 140 is disposed at a preset water level of the water tank 110, alternatively, the sensor 140 may be a liquid level switch, and the liquid level switch is turned off in case that the water level in the water tank 110 is higher than the liquid level switch. Of course, in other embodiments of the present application, the sensor 140 may be other sensors 140 for detecting the liquid level, which is not specifically limited herein.
The dehumidifier 10 further includes a controller 150, where the controller 150 is electrically connected to the sensor 140 and is mainly configured to receive a water level signal transmitted by the sensor 140. The controller 150 is also electrically connected to the water pump 120 and the compressor 130, and is controlled to control the water pump 120 and the compressor 130 accordingly according to the received water level signal.
The controller 150 may be an integrated circuit chip having signal processing capabilities. The controller 150 may be a general-purpose processor, including a central processing unit (Central Processnng Unnt, CPU), a single-chip microcomputer, a micro-control unit (Mncrocontroller Unnt, MCU), a complex programmable logic device (Complex Programmable Lognc Devnce, CPLD), a field programmable gate array (Fneld-Programmable Gate Array, FPGA), an application specific integrated circuit (Applncatnon Specnfnc Nntegrated Cnrcunt, ASNC), an embedded ARM, and other chips, and the controller 150 may implement or execute the methods, steps, and logic blocks disclosed in the embodiments of the present application.
In a possible implementation, the dehumidifier 10 may further include a memory for storing program instructions executable by the controller 150, for example, the dehumidifier 10 control apparatus provided in the embodiment of the present application includes at least one program that may be stored in the memory in the form of software or firmware. The Memory may be a stand-alone external Memory including, but not limited to, random access Memory (Random Access Memory, RAM), read Only Memory (ROM), programmable Read Only Memory (Programmable Read-Only Memory, PROM), erasable Read Only Memory (Erasable Programmable Read-Only Memory, EPROM), electrically erasable Read Only Memory (Electrnc Erasable Programmable Read-Only Memory, EEPROM). The memory may also be provided integrally with the controller 150, for example, the memory may be provided integrally with the controller 150 on the same chip.
Referring to fig. 3, the drainage control method may include the steps of:
in step S100, a water level signal is obtained, the water level signal representing the water level in the water tank 110.
In the present embodiment, the water level in the water tank 110 is detected by the sensor 140, and since the sensor 140 is disposed at the preset water level, the water level signal includes that the water level in the water tank 110 is lower than the preset water level and that the water level in the water tank 110 exceeds the preset water level. Accordingly, the number of the sensors 140 may be provided only one, and the number of the sensors 140 is reduced and the production cost is reduced as compared to the existing dehumidifier 10.
It should be noted that, the dehumidifier 10 may set the water pump 120 mode and set the interactive key, so that the user can manually control the dehumidifier 10 to enter the water pump 120 mode. In addition, the mode of the water pump 120 can be exited by power-off, power-down and interactive key control to clear the abnormal failure of the water pump 120.
Step S200, controlling the water pump 120 to start draining and operate for at least a second preset time under the condition that the water level represented by the water level signal exceeds the preset water level and lasts for at least the first preset time;
during the process of turning on the water pump 120, if the water level represented by the water level signal exceeds the preset water level for at least a third preset time, the compressor 130 and the water pump 120 are controlled to stop running.
In this embodiment, the first preset time may be set to 3 seconds, or may be set to 30 seconds, or may be other time, which is not limited herein, and may be adjusted according to the actual use requirement or use environment. Therefore, the water level in the water tank 110 exceeds the preset water level and the water pump 120 is controlled to start for the first preset time, so that the water pump 120 can be prevented from being started by mistake due to the error of the water level signal obtained instantaneously.
The second preset time may be 10 minutes or 60 minutes, and may of course be set to other times, which is not particularly limited herein. Accordingly, after it is determined that the water in the water tank 110 exceeds the preset water level, the water pump 120 is controlled to start draining for at least a second preset time to ensure that the water level in the water tank 110 is at least lower than the preset water level after the water is drained.
In the process of starting the water pump 120 for the second preset time, the water level signal is still continuously obtained, and in the process, if the water level represented by the obtained water level signal is still higher than the preset water level, the water pump 120 may fail, so that the dehumidifier 10 needs to be immediately controlled to enter a water full protection state, that is, the compressor 130 and the water pump 120 are immediately controlled to stop running, and the fan is controlled to stop running after being delayed for a preset time (for example, 7 seconds) so as to play a role in delaying, radiating and protecting the whole machine; meanwhile, the water full indicator lamp is controlled to flash, and the buzzer continuously buzzes for 5 times, so that all interactive cases except the on-off key of the dehumidifier 10 are invalid, and fault codes are displayed.
It can be seen that by this drain control method, the number of sensors 140 is reduced, so that the entire control logic is performed based on one sensor 140, thus optimizing the control logic of the water pump 120 with respect to the existing dehumidifier 10, and reducing the production cost.
Further, the second preset time may be calculated according to the following formula:
T1＝L1÷Qmax×X；
wherein T1 represents a second preset time, L1 represents the capacity of the water tank 110, qmax represents the maximum drainage flow when the lift of the water pump 120 is 0 meter, X represents the first drainage coefficient, and the value range of the first drainage coefficient is 0.8< X <1.0.
In this embodiment, the second preset time is calculated by the capacity of the water tank 110 and the water discharge flow of the water pump 120, that is, the shortest time required for discharging all the water in the water tank 110 can be ensured, so that the second preset time is set more reasonably.
Alternatively, the first drainage coefficient may be 0.85, 0.9, 0.95, etc., and of course may be other coefficients, which are not particularly limited herein. By setting the first water discharge coefficient to a range of 0.8 to 1.0, it is ensured that the water pump 120 does not discharge all the water in the water tank 110 under the condition of running for a second preset time, thereby avoiding the "dry pumping" of the water pump 120 and protecting the water pump 120.
Further, the third preset time may be calculated according to the following formula:
T2＝L2÷Qmin×Y；
wherein T2 represents a third preset time, L2 represents a difference between a capacity of the water tank 110 and a water capacity of a preset water level, that is, a water capacity of the water tank 110 which can be accommodated by a volume between the preset water level and a maximum water level of the water tank 110, qmin represents a minimum drainage flow rate when a head of the water pump 120 is 5 meters, Y represents a second drainage coefficient, and a value range of the second drainage coefficient is 1.0< Y <1.4.
In this embodiment, the third preset time is calculated by the difference between the capacity of the water tank 110 and the water capacity of the preset water level and the drainage flow of the water pump 120, so that the shortest time required for draining the water exceeding the preset water level from the water tank 110 under the full load condition can be determined, and the second preset time is set more reasonably.
Alternatively, the second drainage coefficient may be 1.1, 1.2, 1.3, etc., but may be other coefficients, which are not particularly limited herein. By setting the first water discharge coefficient to a range of 1.0 to 1.4, it is ensured that the water pump 120 timely discharges the water exceeding the preset water level in the water tank 110 within the second preset time.
Further, referring to fig. 4, in the present embodiment, the drainage control method may further include the following steps:
step S300, acquiring accumulated running time of the water pump 120;
in step S400, in the case where the accumulated running time of the water pump 120 is greater than or equal to the accumulated preset time, the water discharge time of the water pump 120 is set to the fourth preset time.
In this embodiment, the accumulated preset time may be 1000 hours, in other words, after the water pump 120 is operated for a long time, the drainage is attenuated due to its own loss, so it is necessary to reset the fourth preset time to enable the same drainage of the water pump 120 before no loss by extending the drainage time of the water pump 120.
Specifically, the fourth preset time may be obtained according to the following formula:
T3＝T1+M1；
wherein T3 represents a fourth preset time, T1 represents a first preset time, and M1 represents a first compensation time.
Further, the first compensation time is calculated according to the following formula:
M1＝T1×(N-5％)；
wherein M1 represents a first compensation time, T1 represents a second preset time, and N represents a decay rate coefficient of the water pump 120 after the running time of the water pump 120 is greater than or equal to the preset time.
In this embodiment, it can be understood that the attenuation coefficient can be obtained according to parameters such as the material or structure of the water pump 120 itself, and the running time of the new water pump 120 is calculated by calculating the first compensation time and adding the first compensation time to the second preset, so as to ensure that the water discharge of the water pump 120 can reach the same water discharge before the water pump 120 is not worn.
It should be noted that, the operation is stopped after the water pump 120 is operated for the second preset time, or the dehumidifier 10 is turned off and powered down during the operation of the water pump 120, so that the water pump 120 is also stopped.
Accordingly, in a state where the compressor 130 is operated, i.e., in a dehumidification mode, the water tank 110 continuously supplies water; in this case, in the case where the time for which the water pump 120 is stopped is less than or equal to the off-stream preset time, the operation time of the water pump 120 is set to the fifth preset time.
In this embodiment, the shutdown preset time may be determined according to the use condition or the use environment of the dehumidifier 10, and when the shutdown time of the water pump 120 is less than or equal to the shutdown preset time, it is indicated that the water amount in the water tank 110 is too much or the water inflow rate is large, and the water pump 120 needs to be frequently started to drain water, so in this case, the single operation time of the water pump 120 is reset, and the first compensation time, the second compensation time and the second preset time are added to calculate the new operation time of the water pump 120, so that a sufficient amount of water is ensured to be discharged once, and the water pump 120 is prevented from being frequently started, so as to achieve the purpose of protecting the water pump 120.
Specifically, the fifth preset time may be calculated according to the following formula:
T4＝T1+M1+M2；
wherein T4 represents a fifth preset time, T1 represents a second preset time, M1 represents a first compensation time, and M2 represents a second compensation time, and it should be noted that the second compensation time may be obtained by dividing a minimum dehumidification amount per minute by a maximum drainage flow of the water pump 120.
Further, in the case where the accumulated operation time of the water pump 120 is less than the accumulated preset time, and in the state where the compressor 130 is operated, and in the case where the time for which the water pump 120 is stopped is less than or equal to the off-operation preset time, the operation time of the water pump 120 is set to the sixth preset time.
In this embodiment, in the state where the compressor 130 is operated, it is indicated that the dehumidifier 10 is in a dehumidification state, in which case the water tank 110 is continuously fed with water, in order to ensure effective water discharge, the single operation time of the water pump 120 is reset, and the second compensation time and the second preset time are added to calculate the new operation time of the water pump 120, so as to ensure that a sufficient amount of water is discharged once, thereby realizing normal use of the dehumidification function of the dehumidifier 10 while the water pump 120 is discharging water, and improving the user experience.
Specifically, the sixth preset time is calculated according to the following formula:
T5＝T1+M2；
wherein T5 represents a sixth preset time, T1 represents a second preset time, and M2 represents a second compensation time.
Further, referring to fig. 5, the drainage control method may further include the following steps:
step S500, obtaining the continuous running time of the water pump 120;
in step S600, when the continuous operation time of the water pump 120 is greater than or equal to the continuous preset time, or the dehumidifier 10 is in the off state, the operation time of the water pump 120 is cleared.
In this embodiment, the duration preset time may be 60 minutes, and of course, other times may be set, which is not particularly limited herein. The off state of the dehumidifier 10 includes a shutdown state and a power-down state, in which the operation time of the water pump 120 is cleared to avoid repetitive control of the water pump 120, and in the case where the continuous operation time of the water pump 120 is greater than or equal to a continuous preset time.
