Detailed Description
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
In one aspect of the embodiment of the present invention, a method for controlling water full protection is provided, and fig. 1 is a schematic step diagram of the method for controlling water full protection according to the embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
and S1, when the water level signal is a full water signal, converting the unit from the original state to a first state, and maintaining the first state in a first time period t 1.
In the embodiment of the invention, the water level signal is determined by monitoring the state of the water level switch in real time. Generally, when the water level switch is turned off, it indicates that the water level in the water storage device has reached a predetermined water level, and at this time, if water is not drained, the operation of the unit may be affected. The control method of the prior art for water full protection sends a signal to the outside at this time, so that the user can drain water automatically. However, the invention does not inform the user at first, adjusts the state of the water level through different operation states of the unit, outputs the first control information to the unit, enables the unit to be converted into the first state from the original state, and maintains t1, thereby realizing the first automatic drainage. In the embodiment of the invention, the value range of t1 is preferably 2-5 min, and the value range is selected according to the power of the compressor, and more specifically, the larger the power of the compressor is, the longer the time of t1 is.
Further, the unit may include a compressor, a fan, and a water-pumping motor (or other motors, which are not related to water discharge, and are not described in detail herein), wherein when the compressor works, low-pressure gas is lifted to high-pressure gas, so as to achieve a refrigerating effect, thereby generating condensed water, and if the condensed water reaches a certain degree, the condensed water needs to be discharged, thereby preventing the operation of the unit from being affected. When the water fetching motor works, the condensed water generated by the compressor can be fetched to the hotter condenser, so that the condensed water is evaporated, the storage of the condensed water is reduced, and the function of automatic drainage is realized. The fan relies on the mechanical energy of input, improves gas pressure and discharges the gas to realize the function of air supply and heat exchange, in addition, the fan can also blow the comdenstion water, gets rid of and the evaporation of comdenstion water with higher speed.
The original state is a state that the unit normally works, namely the compressor and the fan work, the water fetching motor is turned off, therefore, in the original state, the compressor is turned on to generate condensed water, the fan is turned on to realize heat exchange, and the condensed water is stored in the water storage device because the water fetching motor is turned off. When the water level signal is a full signal, in order to prevent the condensed water from being further stored, it is necessary to prevent the condensed water from being generated and to drain a part of the condensed water stored in the water storage device. At the moment, the unit receives a compressor control instruction and a water pumping motor control instruction, the state of the compressor and the water pumping motor is switched, the compressor is switched from the on state to the off state, the water pumping motor is switched from the off state to the on state, and meanwhile, the on state of the fan is maintained. That is to say, here the unit is in under the first state namely the compressor is the off-state, and fan and the motor of fetching water are operating condition.
And S2, converting the unit from the first state to the second state, and maintaining the second state in a second time period t 2. After t1, the unit receives the control command of the water fetching motor to switch the state of the water fetching motor, and the water fetching motor is switched from the on state to the off state, and meanwhile, the on state of the fan and the off state of the compressor are maintained. Namely, the second working state means that the water pumping motor and the compressor are in a turn-off state, and the fan is in a working state. Therefore, automatic drainage can be realized only by changing the state of the unit without sending signals to external users.
In the embodiment of the invention, the value range of t2 is preferably 15-30 s, and after t2, the water level in the water storage device can be leveled, so that the misjudgment of a water level signal is avoided.
S3, judging whether the water level signal after t2 is a full water signal, if so, converting the unit from the second state to the first state, and maintaining the first state in a third time period t 3; otherwise, the unit is converted from the second state to the original state.
After t2, it is determined whether the current water level signal is a full water signal to prevent excessive water accumulation in the water storage device, and the time for the first automatic water discharge in step S1 is too short to convert the water level signal from a full water signal to a non-full water signal. If current water level signal is full signal, then need further drainage, the unit receives the motor control command of fetching water, switches the state of the motor of fetching water for the motor of fetching water switches into the on-state by the off-state, simultaneously, maintains the on-state of fan and the off-state of compressor, and the state of unit is first state this moment promptly: and starting the water pumping motor and the fan, and turning off the compressor, thereby realizing the second automatic drainage of the unit.
In the embodiment of the invention, similar to t1, the value range of t3 is preferably 2-5 min, and the value range can be selected according to the power of the compressor, and more specifically, the larger the power of the compressor is, the longer the time of t3 is. Of course, t1 may be equal to or different from t 3.
As shown in fig. 2, it should be noted that if the water level signal after t2 is a non-full water signal, it indicates that the water level in the water storage device does not reach the predetermined full water position, at this time, water drainage is no longer needed, the unit receives a compressor control instruction to switch the state of the compressor, and switches the compressor from the off state to the on state, and at the same time, maintains the on state of the fan and the off state of the water-fetching motor, thereby realizing the transition from the second state to the original state.
S4, return S2 and S3; if the number of times of returning to S2 and S3 reaches a predetermined number of times, S2 is performed.
The value range of the preset times n is 0-10, the preset times n are selected according to the current environment of the unit, and generally, the drier the environment is, the smaller the preset times are; the more humid the environment, the greater the predetermined number of times. The step S4 returns to S2 and S3, that is, the water level restoration and the water discharge operation are performed at least one more time, and are performed at most n times. Generally, in step S4, after the unit automatically drains a predetermined number of times, the water level signal may be maintained at a non-full water signal. It should be noted that, after the unit automatically drains the water for the predetermined number of times, the step S2 is performed again to level the current water level and avoid erroneous determination.
But it is also possible that there is a special case: the humidity of current environment is very moist, because the automatic drainage of this unit is mainly by beat the water motor the comdenstion water that the compressor produced beat on hotter condenser to the evaporation condensate water, the evaporation rate of comdenstion water can the step-down this moment, and the speed of unit drainage must not follow the speed that the unit produced water, consequently, must need the intervention of user's manual drainage, just can guarantee the normal work of unit.
In the embodiment of the present invention, the following description proceeds to step S5 by taking the current environment as the dry state and taking the predetermined number of times n as 0 as an example, that is, in step S4, only step S2 is performed, so as to obtain an accurate water level signal.
S5, if the water level signal of S4 is still a full water signal, the unit is converted from the second state to the third state, an output signal is sent to the outside to realize water drainage until the water level signal is not the full water signal, and the unit is converted from the third state to the original state; otherwise, the unit is converted from the second state to the original state.
When the water level signal of the S4 is still a full water signal, the unit receives a fan control instruction to switch the state of the fan, the fan is switched from the on state to the off state, and meanwhile, the off state of the compressor and the water fetching motor is maintained, so that the unit is switched from the second state to the third state.
At the moment, the three motors in the unit are all in a turn-off state, and output signals (which can be sent in a wireless mode or be subjected to sound and light reminding) are sent to the outside to realize water drainage until the water level signals are not full signals. Meanwhile, the unit receives the fan control instruction and the compressor control instruction, switches the state of the compressor and the fan, converts the compressor and the fan from the turn-off state to the turn-on state, and maintains the turn-off state of the water pumping motor. The machine set is in an original state, namely the compressor and the fan are in an opening state, and the water pumping motor is in a closing state, so that the machine set is converted into the original state from the second state.
As shown in fig. 3, after step S4, it is further determined whether the current water level signal is a full water signal, and if the current water level signal is still the full water signal, it indicates that the current environment is too humid, the accumulated water in the water storage device is too much, and the normal operation of the unit may be affected, the unit needs to be turned off, so that the states of the compressor, the water pumping motor, and the fan are all turned off, and an external user is notified to perform manual water drainage.
When the manual drainage by the user (see fig. 3 and 4 for details) is finished or the water level signal of step S4 is a non-full water signal (see fig. 5 for details), it indicates that the water level in the water storage device does not reach the predetermined full water position, at this time, drainage is no longer needed, the state of the unit is converted into the original state to normally work (the unit is converted into the original state from the third state or the unit is converted into the original state from the second state), and the full water protection mechanism is exited until the next full water signal arrives.
Therefore, according to the control method for water full protection, when a water full signal is monitored, the unit cannot be immediately stopped, the compressor is turned off to reduce the generation of condensed water, the water pumping motor is turned on to reduce the water level, the first automatic drainage of the unit is realized, the automatic drainage of a user is avoided, and the frequency of manual operation is reduced; and the water fetching motor is turned off for a period of time, and the water level state after the water fetching motor is restored to be flat is judged, so that the influence of the starting state of the water fetching motor on the water level can be prevented, and the misjudgment of the water level signal is avoided. In addition, the water pumping motor is started again to automatically drain the unit under the condition that the first automatic drainage strength is insufficient, the water level is reduced, so that the automatic drainage of the unit for a preset number of times is realized, and then the unit needs to be turned off if the water level signal is still a water full signal, and external users drain water automatically. Therefore, by one-time or multiple-time automatic drainage, the self-drainage frequency of the user is reduced, and the user experience is optimized.
