Fig. 1 is a method schematic diagram of an embodiment of an air conditioner sterilization control method provided by the invention.
As shown in fig. 1, according to an embodiment of the present invention, the air conditioner sterilization control method includes at least step S110, step S120, and step S130.
And step S110, after the sterilization mode is started, controlling the air conditioner to start a refrigeration mode to generate condensed water, so that the condensed water is stored in a water collecting device of the air conditioner.
Specifically, after the sterilization mode is turned on, the cooling mode is turned on to start cooling to generate condensed water (condensed water), thereby accumulating the condensed water in the water collecting device of the air conditioner. The water collecting device is for example a water pan. Optionally, when the air conditioner is controlled to start the cooling mode, the drainage device of the indoor unit of the air conditioner is turned off. The drainage device is, for example, a water pump, and the water in the water collection device can be drained by the water pump by connecting the water collection device of the air conditioner.
And step S120, detecting whether the water collecting device of the air conditioner finishes water storage.
Preferably, before detecting whether the water collecting device of the air conditioner has finished storing water, detecting whether the pipe temperature of the indoor heat exchanger of the air conditioner is lower than a target temperature; if the temperature of the indoor heat exchanger pipe of the air conditioner is detected to be lower than the target temperature, whether the water storage of the water collecting device of the air conditioner is finished or not is detected; if the temperature of the indoor heat exchanger pipe of the air conditioner is detected to be not lower than the target temperature, at least one of the air volume of an indoor fan, the air volume of an outdoor fan and the frequency of a compressor of the air conditioner is adjusted until the temperature of the indoor heat exchanger pipe of the air conditioner is detected to be lower than the target temperature, and whether the water storage of the water collecting device of the air conditioner is finished or not is detected.
Specifically, if the temperature of the pipe of the indoor heat exchanger of the air conditioner is detected to be lower than the target temperature, which indicates that the indoor heat exchanger meets the condition, the dew condensation stage is started, and whether the water collection device of the air conditioner finishes water storage or not can be detected; if the temperature of the indoor heat exchanger tube of the air conditioner is not lower than the target temperature, the indoor heat exchanger does not meet the condensation condition, the indoor heat exchanger meets the condition by adjusting the air volume of the indoor fan, the air volume of the outdoor fan and/or the frequency of the compressor, and the indoor heat exchanger enters the condensation stage, namely, the temperature of the indoor heat exchanger tube is lower than the target temperature. The low pressure or evaporation temperature can be changed by adjusting the air volume of the indoor fan and the air volume of the outdoor fan, for example, the air volume of the indoor fan can be reduced and/or the air volume of the outdoor fan can be improved; the refrigerant circulation amount can be adjusted by changing the frequency of the compressor, for example, the frequency of the compressor can be increased. For example, the fixed frequency machine can adjust the air volume of the indoor fan and/or the frequency of the compressor, and the frequency converter can adjust at least one of the air volume of the indoor fan, the air volume of the outdoor fan and the frequency of the compressor. The target temperature is equal to the difference between the current dew point temperature and a preset temperature T. Alternatively, the preset temperature T may be set according to actual requirements, for example, when rapid condensation is required, the value of T may be relatively increased.
In some embodiments, the detecting whether the water collecting device of the air conditioner has finished storing water may include: detecting whether a liquid level device arranged in a water collecting device of the air conditioner is disconnected or not; and if the disconnection of the liquid level device is detected, determining that the water collecting device finishes water storage. The liquid level device is for example a liquid level switch. For example, after the air conditioner enters the condensation stage, whether the liquid level device is disconnected or not is detected, if the liquid level device is disconnected, the water storage is completed, and otherwise, the condensation stage is continued until the liquid level device is disconnected.
And step S130, after detecting that the water collecting device finishes storing water, controlling the air conditioner to start a heating mode to heat water in the water collecting device, so that the heated water is used for sterilizing the water collecting device.
Specifically, after the water collecting device of air conditioner accomplished the retaining, the control air conditioner opened the mode of heating to water among the heating water collecting device, thereby realize carrying out pasteurization to water collecting device, avoid breeding the bacterium, and avoid producing the floccule behind the bacterium formative bacterial colony, and then can prevent to cause dirty stifled drainage system to the air conditioner. Dirty stifled mainly because the colony formation in the water collector leads to, and the dry back of pasteurization just can't form the colony, just can solve the stifled problem of part filth.
Optionally, the method further comprises: after the air conditioner is controlled to start a heating mode, detecting whether the water temperature in the water collecting device reaches a target water temperature; and if the water temperature in the water collecting device is detected to reach the target water temperature and the duration time reaches a first preset time, determining that the sterilization of the water collecting device is completed.
Optionally, the method further comprises: after the air conditioner is controlled to start a heating mode, detecting whether the pipe temperature of an indoor heat exchanger reaches a preset temperature protection value and/or whether the exhaust pressure of a compressor reaches a preset pressure protection value; and if the temperature of the pipe of the indoor heat exchanger does not reach the preset temperature protection value and the exhaust pressure of the compressor does not reach the preset pressure protection value, controlling the air quantity of the indoor fan to be reduced, the air quantity of the outdoor fan to be increased and/or the frequency of the compressor to be increased.
Specifically, heating under severe conditions, and if the temperature of the inner pipe is detected to be too high, the air conditioner is controlled to stop; the high-pressure of the outdoor unit is too high and exceeds the range of the high-pressure switch, and the outdoor unit can be tripped. If the heating mode is started, and the temperature of the inner fan and the high pressure of the outer fan are detected to be within the normal operation range, the air quantity of the inner fan is reduced (the inner fan is enabled to operate at a low speed) and the air quantity of the outer fan is increased (the outer fan is enabled to operate at a high speed), so that the water heating of the water collecting device can be accelerated until the water temperature of the water collecting device can meet the requirement of the target water temperature.
And if the temperature of the indoor heat exchanger tube reaches a preset temperature protection value and/or the exhaust pressure of the compressor reaches a preset pressure protection value, adjusting at least one of the rotating speed of an indoor fan, the rotating speed of an outdoor fan and the frequency of the compressor according to the time for the temperature of the indoor heat exchanger tube to reach the preset temperature protection value and/or the time for the exhaust pressure of the compressor to reach the preset pressure protection value.
Specifically, if the temperature of the inner pipe reaches the preset temperature protection value and/or the high-voltage detection device of the outdoor unit is disconnected (the exhaust pressure of the compressor reaches the preset pressure protection value, the high-voltage detection device is disconnected), the rotating speed of the indoor fan, the rotating speed of the outer fan and/or the frequency of the compressor are/is adjusted according to the time from the heating mode to the preset temperature protection value and/or the time from the heating mode to the high-voltage detection device, at least one of the rotating speed of the indoor fan, the rotating speed of the outdoor fan and the frequency of the compressor is/are increased, the reliability of the system is improved, and meanwhile, the temperature rise of the water collecting device is improved to the maximum extent.
For example, a time length threshold value t is set, and if the time length for the pipe temperature of the indoor heat exchanger to reach a preset temperature protection value and the time length for the exhaust pressure of the compressor to reach a preset pressure protection value are both smaller than the value t, the rotating speed of the indoor fan is increased, the rotating speed of the outdoor fan is reduced, and the frequency of the compressor is reduced; if the time for the temperature of the indoor heat exchanger tube to reach the preset temperature protection value and the time for the exhaust pressure of the compressor to reach the preset pressure protection value are both greater than the value t, the rotating speed of the outdoor fan is reduced, the rotating speed of the indoor fan and the frequency of the compressor operate according to the current state, and if protection still occurs (namely the temperature of the inner tube is detected to reach the preset temperature protection value and/or the high-pressure detection device of the outdoor unit is detected to be disconnected), the frequency of the compressor is reduced or the rotating speed of the inner fan is increased; if the time for the pipe temperature of the indoor heat exchanger to reach the preset temperature protection value is less than the t value, and the time for the exhaust pressure of the compressor to reach the preset pressure protection value is more than the t value, the rotating speed of the outdoor fan is reduced, the rotating speed of the indoor fan and the frequency of the compressor run according to the current state, and if protection still occurs, the frequency of the compressor is reduced; if the time for the pipe temperature of the indoor heat exchanger to reach the preset temperature protection value is longer than the t value, and the time for the exhaust pressure of the compressor to reach the preset pressure protection value is shorter than the t value, the frequency of the compressor is reduced, the rotating speed of the outdoor fan and the rotating speed of the indoor fan operate according to the current state, and if protection still occurs, the rotating speed of the indoor fan is increased.
Fig. 2 is a schematic method diagram of another embodiment of the air conditioner sterilization control method provided by the invention.
As shown in fig. 2, according to another embodiment of the present invention, the air conditioner sterilization control method further includes step S140 and step S150.
And step S140, after the water collecting device is sterilized, starting a drainage device of the indoor unit of the air conditioner for drainage, and detecting whether the water in the water collecting device is drained completely.
And S150, if the water in the water collecting device is detected to be drained completely, controlling the air conditioner to continuously heat for a second preset time and then closing the air conditioner.
Specifically, whether water in the water collecting device is drained or not is determined by detecting whether a liquid level device (such as a liquid level switch) arranged in the water collecting device is closed or not, if the liquid level device is closed, the water in the water collecting device is drained, the water draining device is closed, and meanwhile, in order to avoid the situation that the water in the water collecting device is not completely drained, the operation is stopped after the heating operation is continued for a second preset time. And if the liquid level device is not closed, the water in the water collecting device is not drained, and the drainage device continues to operate.
Fig. 3 is a flow chart diagram of an air conditioner sterilization control method provided by the invention.
As shown in fig. 3, the refrigeration mode is started, the water storage stage of the water collecting device is entered, and then whether the water storage amount is met is judged, if not, the refrigeration is continuously operated, the value of the preset temperature T can be adjusted according to the requirement to carry out rapid water storage, if so, the heating mode is switched to carry out sterilization, and after the heating sterilization is entered, whether the sterilization requirement is met (whether the target water temperature is met) is judged, if so, the air conditioner is stopped; if the sterilization requirement is not met, the rotating speeds of the inner fan and the outer fan and/or the frequency of the compressor are intelligently adjusted according to the conditions of the inner pipe temperature or the pressure device, and the quick sterilization effect is achieved.
For clearly explaining the technical solution of the present invention, the following describes an execution flow of the air conditioner sterilization control method provided by the present invention with a specific embodiment.
Fig. 4 is a schematic method diagram of an embodiment of a sterilization method for an air conditioner according to the present invention. As shown in fig. 4, according to an embodiment of the present invention, the air conditioner sterilization mode may include: a condensation stage, a water storage stage, a heating sterilization stage and a drying stage. After the opening of the sterilization mode of the air conditioner is detected, the refrigeration mode is opened to generate condensed water, and meanwhile, an indoor unit drainage device (such as a water pump) is closed. The temperature of the pipe of the indoor heat exchanger (evaporator) and the ambient temperature are detected, if the air conditioner is provided with a humidity sensor, the corresponding dew point temperature (which changes along with the change of the ambient temperature and the humidity) is calculated according to the ambient temperature and the humidity; without a humidity sensor, a fuzzy dew point temperature is calculated based on the ambient temperature and the corresponding fuzzy humidity (providing an approximate humidity or a low limit humidity corresponding to the ambient temperature). Judging whether the tube temperature (or inner tube temperature for short) of the indoor heat exchanger is lower than a target temperature (dew point temperature-T), if so, entering a condensation stage, otherwise, adjusting the air quantity of an indoor fan, the air quantity of an outdoor fan and/or the frequency of a compressor (the air quantity is adjusted by a fixed frequency machine, and the frequency converter can also adjust an outer fan and the compressor) until the temperature of the inner tube is lower than the target temperature, and entering the condensation stage.
And after the air conditioner enters the condensation stage, detecting whether the liquid level device is disconnected, if so, indicating that the water storage stage is finished, otherwise, continuing the condensation stage until the liquid level device is detected to be disconnected.
After the air conditioner finishes the water storage stage (detects that the liquid level device is disconnected), the system starts a heating mode, and detects whether the temperature of the inner pipe reaches a preset temperature protection value and/or whether the high-voltage detection device of the outdoor unit is disconnected (because the system operates and heats in a severe environment, the detection function needs to be added to ensure the reliable operation of the system). If the temperature of the inner pipe reaches the preset temperature protection value or the disconnection of the outer machine high-voltage detection device is detected, the rotating speed of the indoor fan (increasing the rotating speed of the indoor fan), the rotating speed of the outer fan (reducing the rotating speed of the outdoor fan) and/or the frequency of the compressor (reducing the frequency of the compressor) are/is adjusted according to the time consumption for the temperature of the inner pipe to reach the temperature protection value, so that the reliability of the system is met, and the temperature rise of the water collecting device is increased to the maximum extent. And if the heating mode is started, and the temperature of the inner fan and the high pressure of the outer fan are detected to be within the normal operation range, executing the low-rotation-speed (the air volume of the inner fan is reduced) and high-rotation-speed (the air volume of the outer fan is increased) operation of the inner fan until the water temperature of the water collecting device can meet the requirement of the target water temperature.
And after the air conditioner finishes the heating and sterilizing stage, a system drainage device is started, whether the liquid level device is closed or not is detected, and if the liquid level device is detected to be closed, the air conditioner is closed after the air conditioner continues heating and running for t2 time. Otherwise, the drainage device continues to operate.
Fig. 5 is a block diagram of an embodiment of an air conditioner sterilization control device according to the present invention. As shown in fig. 5, the sterilization control apparatus 100 includes a control unit 110 and a first detection unit 120.
The control unit 110 is configured to control the air conditioner to turn on the cooling mode to generate condensed water after the sterilization mode is turned on, so that the condensed water is stored in a water collecting device of the air conditioner.
Specifically, after the sterilization mode is turned on, the cooling mode is turned on to start cooling to generate condensed water (condensed water), thereby accumulating the condensed water in the water collecting device of the air conditioner. The water collecting device is for example a water pan. Alternatively, the control unit 110 turns off the drain of the indoor unit of the air conditioner when controlling the air conditioner to turn on the cooling mode. The drainage device is, for example, a water pump, and the water in the water collection device can be drained by the water pump by connecting the water collection device of the air conditioner.
The first detection unit 120 is used to detect whether the water collecting device of the air conditioner has finished storing water.
Preferably, the apparatus 100 further comprises a second detection unit and a first adjustment unit (not shown). The second detection unit is used for detecting whether the pipe temperature of the indoor heat exchanger of the air conditioner is lower than a target temperature before the first detection unit detects whether the water storage of the water collecting device of the air conditioner is finished, wherein the target temperature is equal to the difference between the current dew point temperature and the preset temperature; if the temperature of the indoor heat exchanger tube of the air conditioner is detected to be lower than the target temperature, the first detection unit 120 detects whether the water collection device of the air conditioner finishes storing water; a first adjusting unit, configured to adjust at least one of an indoor fan air volume, an outdoor fan air volume, and a compressor frequency of the air conditioner if the second detecting unit detects that the temperature of the indoor heat exchanger tube of the air conditioner is not lower than a target temperature, until the second detecting unit detects that the temperature of the indoor heat exchanger tube is lower than the target temperature, the first detecting unit 120 detects whether the water collecting device of the air conditioner has finished storing water.
Specifically, if the temperature of the pipe of the indoor heat exchanger of the air conditioner is detected to be lower than the target temperature, which indicates that the indoor heat exchanger meets the condition, the dew condensation stage is started, and whether the water collection device of the air conditioner finishes water storage or not can be detected; if the temperature of the indoor heat exchanger tube of the air conditioner is not lower than the target temperature, the indoor heat exchanger does not meet the condensation condition, the indoor heat exchanger meets the condition by adjusting the air volume of the indoor fan, the air volume of the outdoor fan and/or the frequency of the compressor, and the indoor heat exchanger enters the condensation stage, namely, the temperature of the indoor heat exchanger tube is lower than the target temperature. The low pressure or evaporation temperature can be changed by adjusting the air volume of the indoor fan and the air volume of the outdoor fan, for example, the air volume of the indoor fan can be reduced and/or the air volume of the outdoor fan can be improved; the refrigerant circulation amount can be adjusted by changing the frequency of the compressor, for example, the frequency of the compressor can be increased. For example, the fixed frequency machine can adjust the air volume of the indoor fan and/or the frequency of the compressor, and the frequency converter can adjust at least one of the air volume of the indoor fan, the air volume of the outdoor fan and the frequency of the compressor. The target temperature is equal to the difference between the current dew point temperature and a preset temperature T. Alternatively, the preset temperature T may be set according to actual requirements, for example, when rapid condensation is required, the value of T may be relatively increased.
In some embodiments, the detecting of whether the water collecting device of the air conditioner has finished storing the water by the first detecting unit 120 may include: detecting whether a liquid level device arranged in a water collecting device of the air conditioner is disconnected or not; and if the disconnection of the liquid level device is detected, determining that the water collecting device finishes water storage. The liquid level device is for example a liquid level switch. For example, after the air conditioner enters the condensation stage, whether the liquid level device is disconnected or not is detected, if the liquid level device is disconnected, the water storage is completed, and otherwise, the condensation stage is continued until the liquid level device is disconnected.
The control unit 110 is further configured to: after the first detection unit detects that the water collecting device finishes storing water, the air conditioner is controlled to start a heating mode to heat water in the water collecting device, so that the heated water is used for sterilizing the water collecting device.
Specifically, after the water collecting device of air conditioner accomplished the retaining, the control air conditioner opened the mode of heating to water among the heating water collecting device, thereby realize carrying out pasteurization to water collecting device, avoid breeding the bacterium, and avoid producing the floccule behind the bacterium formative bacterial colony, and then can prevent to cause dirty stifled drainage system to the air conditioner. Dirty stifled mainly because the colony formation in the water collector leads to, and the dry back of pasteurization just can't form the colony, just can solve the stifled problem of part filth.
Optionally, the apparatus 100 further comprises a third detection unit and a determination unit (not shown).
A third detecting unit, configured to detect whether a water temperature in the water collecting device reaches a target water temperature after the control unit 110 controls the air conditioner to start a heating mode; and the determining unit is used for determining that the sterilization of the water collecting device is finished if the third detecting unit detects that the water temperature in the water collecting device reaches the target water temperature and the duration of the water temperature reaches a first preset duration.
Optionally, the control unit 110 further includes a fourth detection unit and a second adjustment unit (not shown).
A fourth detecting unit, configured to detect whether a temperature of an indoor heat exchanger tube reaches a preset temperature protection value and/or whether a compressor discharge pressure reaches a preset pressure protection value after the control unit 110 controls the air conditioner to start a heating mode; a second adjusting unit, configured to adjust an indoor fan speed, an outdoor fan speed, and/or a compressor frequency according to a duration for a temperature of the indoor heat exchanger tube to reach a preset temperature protection value or a duration for an exhaust pressure of the compressor to reach the preset pressure protection value, if the fourth detecting unit detects that the temperature of the indoor heat exchanger tube reaches the preset temperature protection value or the exhaust pressure of the compressor reaches the preset pressure protection value; if the fourth detection unit detects that the pipe temperature of the indoor heat exchanger does not reach the preset temperature protection value and the exhaust pressure of the compressor does not reach the preset pressure protection value, the air quantity of the indoor fan is controlled to be reduced, the air quantity of the outdoor fan is controlled to be increased and/or the frequency of the compressor is controlled to be increased.
Specifically, heating under severe conditions, and if the temperature of the inner pipe is detected to be too high, the air conditioner is controlled to stop; the high-pressure of the outdoor unit is too high and exceeds the range of the high-pressure switch, and the outdoor unit can be tripped. If the heating mode is started, and the temperature of the inner fan and the high pressure of the outer fan are detected to be within the normal operation range, the air quantity of the inner fan is reduced (the inner fan is enabled to operate at a low speed) and the air quantity of the outer fan is increased (the outer fan is enabled to operate at a high speed), so that the water heating of the water collecting device can be accelerated until the water temperature of the water collecting device can meet the requirement of the target water temperature.
If the fourth detection unit detects that the temperature of the indoor heat exchanger tube reaches a preset temperature protection value and/or the exhaust pressure of the compressor reaches a preset pressure protection value, adjusting at least one of the rotating speed of the indoor fan, the rotating speed of the outdoor fan and the frequency of the compressor according to the time length for the temperature of the indoor heat exchanger tube to reach the preset temperature protection value and/or the time length for the exhaust pressure of the compressor to reach the preset pressure protection value.
Specifically, if the temperature of the inner pipe reaches the preset temperature protection value and/or the high-voltage detection device of the outdoor unit is disconnected (the exhaust pressure of the compressor reaches the preset pressure protection value, the high-voltage detection device is disconnected), at least one of the rotating speed of the indoor fan, the rotating speed of the outer fan and the frequency of the compressor is adjusted according to the time from the heating mode to the preset temperature protection value of the inner pipe and/or the time from the heating mode to the disconnection of the high-voltage detection device, so that the rotating speed of the indoor fan is increased, the rotating speed of the outdoor fan is reduced, and/or the frequency of the compressor is reduced, the reliability of the system is met, and meanwhile, the temperature rise of the water collecting device is improved.
For example, a time length threshold value t is set, and if the time length for the pipe temperature of the indoor heat exchanger to reach a preset temperature protection value and the time length for the exhaust pressure of the compressor to reach a preset pressure protection value are both smaller than the value t, the rotating speed of the indoor fan is increased, the rotating speed of the outdoor fan is reduced, and the frequency of the compressor is reduced; if the time for the temperature of the indoor heat exchanger tube to reach the preset temperature protection value and the time for the exhaust pressure of the compressor to reach the preset pressure protection value are both greater than the value t, the rotating speed of the outdoor fan is reduced, the rotating speed of the indoor fan and the frequency of the compressor operate according to the current state, and if protection still occurs (namely the temperature of the inner tube is detected to reach the preset temperature protection value and/or the high-pressure detection device of the outdoor unit is detected to be disconnected), the frequency of the compressor is reduced or the rotating speed of the inner fan is increased; if the time for the pipe temperature of the indoor heat exchanger to reach the preset temperature protection value is less than the t value, and the time for the exhaust pressure of the compressor to reach the preset pressure protection value is more than the t value, the rotating speed of the outdoor fan is reduced, the rotating speed of the indoor fan and the frequency of the compressor run according to the current state, and if protection still occurs, the frequency of the compressor is reduced; if the time for the pipe temperature of the indoor heat exchanger to reach the preset temperature protection value is longer than the t value, and the time for the exhaust pressure of the compressor to reach the preset pressure protection value is shorter than the t value, the frequency of the compressor is reduced, the rotating speed of the outdoor fan and the rotating speed of the indoor fan operate according to the current state, and if protection still occurs, the rotating speed of the indoor fan is increased.
Optionally, the control unit 110 is further configured to: after the water collecting device is sterilized, starting a drainage device of an indoor unit of the air conditioner for drainage; the first detection unit 120 is further configured to: detecting whether water in the water collecting device is drained completely; the control unit 110 is further configured to: if the first detection unit 110 detects that the water in the water collecting device is drained completely, the air conditioner is controlled to continue heating and operate for a second preset time period and then is turned off.
Specifically, the first detecting unit 120 determines whether water in the water collecting device is drained completely by detecting whether a liquid level device (e.g., a liquid level switch) provided in the water collecting device is closed, and if the liquid level device is closed, which indicates that water in the water collecting device is drained completely, the water draining device is closed, and meanwhile, in order to avoid that water in the water collecting device is not completely drained completely, the operation is stopped after the heating operation is continued for a second preset time period. And if the liquid level device is not closed, the water in the water collecting device is not drained, and the drainage device continues to operate.
