Detailed Description
In order to make the objects, technical solutions and advantages of the present application more clear, the present application will be further described in detail with reference to the accompanying drawings.
For convenience of understanding, an application scenario of the condensation detection method, the method for reducing condensation and the air conditioner provided by the embodiment of the application is explained first.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an air conditioner according to an embodiment of the present disclosure. As can be seen from fig. 1, the air conditioner in the present application includes a housing 1, an air outlet is formed on a side wall of the housing 1, and an air deflector 2 for closing the air outlet is rotatably connected to the housing 1; with continued reference to fig. 1, a plurality of condensation detection units 3 are disposed on the side wall of the housing 2 around the air outlet; meanwhile, the shell 1 is also internally provided with common parts of the air conditioner in the prior art, thereby forming a complete air conditioner.
The shell 1 is also internally provided with a controller which is in signal connection with the air deflector 2. When the air conditioner is used, when the air conditioner operates in a refrigeration mode or a dehumidification mode, whether condensation is generated at the air outlet of the air conditioner or not, the amount of the condensation generated and the position of the condensation generated can be detected through the electric signal of the condensation detection unit 3, then the controller adjusts the position of the air deflector and/or adjusts the rotating speed of the evaporator side fan and/or the condenser side fan according to the detected amount of the condensation generated and the position of the condensation generated, and therefore condensation is prevented from being continuously generated at the air outlet of the air conditioner.
Further, when specifically setting the condensation detection unit 3, reference may be made to fig. 2, and fig. 2 is a schematic structural diagram of the condensation detection unit provided in the embodiment of the present application. As can be seen from fig. 2, the condensation detection unit 3 includes a unit grid 6 that is provided on the housing 1 and located around the air outlet, and a long side of the unit grid 6 is parallel to the air outlet; with continued reference to fig. 2, two opposing long sides of each unit cell 6 are fixedly connected with electrodes 4, thereby forming an electrode pair, which is connected to a main board 5 by a wire. When the condensation is detected, the judgment can be carried out through the electric signals of the electrode pair, and the electric signals can be current signals or capacitance signals of the electrode pair. Illustratively, the main board 5 and each pair of electrodes 4 form a circuit, when condensation is generated, the condensation can make the two electrodes 4 in the pair of electrodes be in conductive communication, the main board 5 determines the generation position of the condensation by detecting the conductive communication or capacitance value reduction ratio of each electrode pair, and determines the generation amount of the condensation by detecting the conductive communication ratios of a plurality of electrode pairs; and then the controller adjusts the position of the air deflector and/or adjusts the fan at the evaporator side and/or adjusts the rotating speed of the fan at the condenser side according to the detected condensation generation amount and the condensation generation position, so that condensation at the air outlet of the air conditioner is prevented from being continuously generated subsequently. In addition to detecting the current value of the electrode pair, the capacitance value of the electrode pair can be detected. When condensation occurs between the two electrodes 4, the capacitance value corresponding to the electrode 4 is changed after the electrode 4 is conducted, and therefore, the position of the condensation and the amount of the condensation can be detected by detecting the change of the capacitance value signal of any electrode pair.
As an alternative, the main board 5 may be a control unit with the controller. For specific connection between the electrode pair and the main board 5, reference is made to fig. 3, and fig. 3 is a schematic connection diagram of the electrode and the main board according to an embodiment of the present disclosure. As can be seen from fig. 3, the two electrodes 4 in each electrode pair are respectively connected to the main board 5 through wires.
When the air conditioner is used, a plurality of electrode pairs for detecting condensation are arranged at the air outlet of the air conditioner; when the position of each electrode pair generates condensation, the two electrodes 4 in each electrode pair are in conductive communication; the generation position of dew is determined by detecting the conductive connection or capacitance value decrease ratio of each electrode pair, and the generation amount of dew is determined by detecting the conductive connection ratio of a plurality of electrode pairs. When the main board 5 detects that the condensation generation amount exceeds a first set value, the rotating speed of the evaporator side fan can be increased, the rotating speed of the evaporator side fan is increased, and the air volume blown out in unit time is increased, so that the temperature of the blown air conditioner is increased; and reduce the rotational speed of condenser side fan, the rotational speed of condenser side fan reduces, can make the condensation temperature of condenser rise, after the throttle, the refrigerant temperature that gets into the evaporimeter can rise, the evaporating temperature of evaporimeter also rises thereupon, thereby make the cold wind temperature that blows off through the evaporimeter rise, thereby make the temperature that the air conditioner that blows off blown off rise, thereby make the temperature of air outlet department rise, reduce the temperature difference of the cold and hot exchange front of air outlet department, reduce the risk that air outlet department continues to produce the condensation. The first setting value may be 1/3, 1/2, and other different values.
In the present application, reference may be made to fig. 5 for a specific method for detecting condensation, and fig. 5 is a flowchart of a method for reducing condensation according to an embodiment of the present application.
As can be seen from fig. 4, the specific method for detecting condensation is as follows: detecting an electric signal of a condensation detection unit at an air outlet of the air conditioner; and the amount of condensation generated on the air outlet of the air conditioner and the position of the condensation generated are determined by detecting the electric signal of the condensation detection unit.
When specifically detecting, lead to the condensation detecting element's of detecting the air outlet department of air conditioner signal specifically to be: the condensation detection unit is a plurality of electrode pairs which are arranged at an air outlet of the air conditioner and used for detecting condensation; when the position of each electrode pair generates condensation, the electric signal in each electrode pair changes; the position of the generation of the condensation is determined by detecting the condition of the electric signals of each electrode pair, and the generation amount of the condensation is determined by detecting the proportion of the change of the electric signals of a plurality of electrode pairs. As can be seen from the description in the above structure, the electrical signal may be a current signal between the pair of electrodes, or a capacitance value signal of the pair of electrodes.
During detection, the generation of condensation can be judged through the capacitance value signal or the current signal, and the generation amount of condensation can be judged through the position of the electrode pair and the proportion of the electrode pair generating the capacitance value signal change or the current signal change. Illustratively, the main board 5 and each pair of electrodes 4 form a circuit, when condensation occurs, the condensation makes the two electrodes 4 in the pair of electrodes in conductive communication, the main board 5 determines the generation position of the condensation by detecting the conductive communication or capacitance value reduction ratio of each electrode pair, and determines the generation amount of the condensation by detecting the conductive communication ratios of a plurality of electrode pairs; and then the controller adjusts the position of the air deflector and/or adjusts the fan at the evaporator side and/or adjusts the rotating speed of the fan at the condenser side according to the detected condensation generation amount and the condensation generation position, so that condensation at the air outlet of the air conditioner is prevented from being continuously generated subsequently. In addition to detecting the current value of the electrode pair, the capacitance value of the electrode pair can be detected. When condensation occurs between the two electrodes 4, the capacitance value corresponding to the electrode 4 is changed after the electrode 4 is conducted, and therefore, the position of the condensation and the amount of the condensation can be detected by detecting the change of the capacitance value signal of any electrode pair.
In addition, the determination of the dropping of the condensation can be made by a capacitance value signal or a current value signal. For example, when the current signal of any electrode pair is weakened or the capacitance signal of any electrode pair is weakened, it is determined that condensation and dripping are generated at the position of the electrode pair. That is, the condition of the generated condensation can be judged through the change of the electric signals of the electrode pair, and the generated condensation can be judged to be larger at the moment. When the detection is performed, the amount of dew generation can be specifically determined by the change of the electric signal.
When the condensation is specifically reduced, after the condensation is detected by the method for detecting the condensation, the position of the air deflector and/or the position of the evaporator side fan and/or the rotating speed of the condenser side fan are/is adjusted according to the detected condensation generation amount and the detected condensation generation position.
When the air conditioner operates in a cooling mode or a dehumidification mode, when the air deflector 2 of the air conditioner is in a horizontal or vertical state, and when the electrode pair conduction communication or the capacitance value reduction of at least a second set value (such as 1/3, 1/4, 1/5 and the like) of the plurality of electrode pairs is detected within the set time (such as different time of 10min, 15min, 20min and the like) of the starting operation of the air conditioner, it indicates that the condensation speed of the air conditioner is high at the moment, and the controller controls the rotating speed of the evaporator side fan to be adjusted to a high wind level at the moment. The rotating speed of the evaporator side fan is increased, and the air volume blown out in unit time is increased, so that the temperature of the blown air of the air conditioner is increased. In addition, the rotational speed of controller control condenser side fan reduces to low wind shelves, when the rotational speed of condenser side fan reduces, can make the condensation temperature of condenser rise, after the throttle, the refrigerant temperature that gets into the evaporimeter can rise, the evaporating temperature of evaporimeter also rises thereupon, thereby make the cold wind temperature that blows off through the evaporimeter rise, thereby make the temperature that the air conditioner that blows off blown off rise, thereby through mutually supporting of evaporimeter and condenser, make the temperature of air outlet department rise, reduce the temperature difference of air outlet department heat-exchanger cold-hot frontal, reduce the follow-up risk that continues to produce the condensation of air outlet department.
In addition, when the electrode pair of at least a fifth set value (such as 1/5, 1/4 and the like) in a plurality of electrode pairs is detected to be changed from conductive connection to disconnection, condensation drop can be judged to be generated, and at the moment, the rotation speed of the fan on the evaporator side is controlled to be adjusted to a high wind level; and the rotating speed of a fan at the condenser side is controlled to be adjusted to a low wind level, so that the generation amount of condensation is reduced.
Further, when the air conditioner operates in the cooling mode or the dehumidification mode, and when the air deflector 2 is in a state of being left, right, upward or downward, when the controller detects that at least a pair of electrodes of a third set value (such as 1/3, 1/4, 1/5, and the like) in the plurality of electrode pairs is in conductive communication or the capacitance value is reduced, it indicates that a small amount of condensation has been generated at the air outlet of the air conditioner, and at this time, the controller controls the air deflector to turn to vertical or horizontal, so as to reduce the risk of condensation continuing to be generated at the air outlet subsequently. As an alternative, a third set point that is less than the second set point may be used.
Further, the concrete principle of the aforesaid reduction risk of producing condensation is that, when upper and lower aviation baffle and left and right aviation baffle are in the inclined position, to the cold wind guide effect that blows off from the air outlet, when cold wind blows off from the air outlet, because resistance effect can make a small part of cold wind turn back the air outlet local, make air outlet local temperature reach below the dew point temperature, consequently produce the condensation on the cold and hot difference in temperature crossing face of these local more easily. Meanwhile, when the upper air deflector, the lower air deflector, the left air deflector and the right air deflector are in inclined positions, the area of an air outlet is reduced, the air outlet temperature is reduced, and condensation is more likely to occur on the side with larger air volume. Therefore, when the upper air deflector, the lower air deflector and the left air deflector are adjusted to be vertical or horizontal, the reduction of the local temperature of the air outlet by the partially folded cold air is reduced, the area of the air outlet is increased, the air outlet temperature is increased, and the continuous occurrence of the condensation phenomenon at the air outlet is reduced.
Further, after the air deflector is adjusted to be in a horizontal or vertical state, when the controller detects that at least a second set value of the electrode pairs is in conductive communication or the capacitance value is reduced, it indicates that a large amount of condensation is generated at the air outlet of the air conditioner at the moment, the risk of subsequent condensation generation at the air outlet cannot be reduced only by adjusting the position of the air deflector, the controller controls the rotating speed of the evaporator side fan to be adjusted to a high wind level, at the moment, the rotating speed of the evaporator side fan is increased, the air volume blown out in unit time is increased, the temperature of the blown air of the air conditioner is increased, the temperature at the air outlet is increased, the temperature difference of the cold-heat exchange frontal surface at the air outlet is reduced, and the risk of subsequent condensation generation at the air outlet is reduced.
Furthermore, when the air deflector is adjusted to be in a horizontal or vertical state, and the rotation speed of the fan at the evaporator side is adjusted to be in a high wind level, when the controller detects that at least a second set value of the electrode pair in the electrode pair positioned on the same side of the air outlet is in conductive communication or the capacitance value is reduced, or at least continuous conductive communication of a fourth set value (such as 1/2, 1/3, 1/4 and the like) in a plurality of electrode pairs is detected, it is indicated that more condensation is generated at the air outlet of the air conditioner at the moment, the risk of subsequent continuous condensation generation at the air outlet cannot be reduced only by adjusting the position of the air deflector and increasing the rotation speed of the fan at the evaporator side, at the moment, the controller can control the rotation speed of the fan at the condenser side to be adjusted to be in a low wind level, at the moment, the rotation speed of the fan at the condenser is reduced, the condensation temperature of the condenser is increased, and the temperature of the refrigerant entering the evaporator is increased after throttling, the evaporating temperature of the evaporator rises along with the temperature rise of the cold air blown out by the evaporator, so that the temperature of the air blown out by the air conditioner rises, the temperature of the air outlet rises through the mutual matching of the evaporator and the condenser, the temperature of the air outlet rises, the temperature difference of the cold-heat exchange front surface of the air outlet is reduced, and the risk of condensation generated by the follow-up continuation of the air outlet is reduced.
