The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
Referring to fig. 1 to 4, a method for controlling condensation prevention of a cabinet air conditioner according to the present invention will be described. Wherein, fig. 1 is a flow chart of the anti-condensation control method for the cabinet air conditioner of the present invention; FIG. 2 is a schematic diagram of the liquid sensor arrangement of the packaged air conditioner of the present invention; FIG. 3 is a schematic view of a first swing blade of the packaged air conditioner according to the present invention; fig. 4 is a schematic structural view of a second swing vane of the cabinet air conditioner according to the present invention.
As shown in fig. 2, in order to solve the problems of low control precision and poor user experience of the existing anti-condensation control method, the cabinet air conditioner (hereinafter referred to as air conditioner for short) of the present invention mainly includes a housing 1 and a strip-shaped air outlet 2 disposed on the housing 1, wherein the length in the vertical direction (i.e., the first direction) is greater than the length in the horizontal direction (i.e., the second direction). The air outlet 2 is provided with an air guiding portion 3, and referring to fig. 3 and 4, the air guiding portion 3 includes a first swing blade 31 and a second swing blade 32, the first swing blade 31 can swing in the vertical direction, and the second swing blade 32 can swing in the horizontal direction. The cabinet air conditioner further comprises functional components, specifically, two fans (not shown in the figure) for realizing indoor air flow and two compressors (not shown in the figure) for realizing refrigerant flow, wherein the air outlet 2 is divided into an upper area and a lower area along the vertical direction, and each area is correspondingly provided with one fan. In addition, a plurality of liquid sensors capable of detecting humidity are further disposed at different positions of the outlet 2, as shown in fig. 2, specifically, the liquid sensors are six humidity sensors, one is disposed in the vertical direction on each of the upper and lower sides of the outlet 2, and the liquid sensors are respectively a first sensor 21 and a second sensor 22, and one is disposed in the horizontal direction on each of the left and right sides of the upper and lower areas of the outlet 2, and the liquid sensors are respectively a third sensor 23 and a fourth sensor 24.
Referring back to fig. 1, the anti-condensation control method for an air conditioner of the present invention mainly includes the steps of:
s100, acquiring a humidity value detected by each humidity sensor, for example, a control unit of the air conditioner acquires humidity values acquired by the six humidity sensors at the same time;
s200, calculating a difference value between each humidity value and the corresponding humidity threshold, for example, after the control unit acquires the humidity values acquired by the six humidity sensors, calculating the difference values between the humidity values acquired by the remaining humidity sensors and the corresponding humidity thresholds respectively;
s300, comparing the magnitude of each difference value with the corresponding first reference difference value and/or second reference difference value, for example, the first reference difference value is smaller than the second reference difference value, and after calculating the difference values, the control unit respectively compares the remaining difference values with the corresponding first reference difference value and second reference difference value;
s400, selectively controlling the wind guiding direction and/or the operating state of the functional component of the wind guiding portion 3 based on the comparison result, for example, when a difference between a humidity value collected by one of the six humidity sensors and the corresponding humidity threshold is greater than a first reference difference and smaller than a second reference difference, controlling the swing blade corresponding to the sensor to swing in a direction opposite to the direction in which the humidity sensor is located, and for example, when a difference between humidity values collected by a plurality of sensors among the six humidity sensors and the corresponding humidity threshold is greater than the second reference difference, controlling the swing blade to swing in the opposite direction, further controlling the fan to perform a speed reduction operation, and/or controlling the compressor to perform a frequency reduction operation.
As can be seen from the above description, the air outlet 2 is divided into a plurality of areas by arranging the plurality of humidity sensors, and the humidity of each area is collected and compared, so that the control accuracy of the anti-condensation control method for the air outlet 2 of the air conditioner can be effectively improved, and the user experience is improved. Specifically, by arranging a plurality of humidity sensors at different positions of the air outlet 2, the control method can be used for detecting the humidity at different positions of the air outlet 2 in a targeted manner and based on the detection result: when the humidity of an individual or partial position is high, the risk of generating condensation exists, and the corresponding swing blade is controlled to swing in the opposite direction, so that condensation prevention control is performed on the area in a targeted manner on the premise of ensuring the operation effect of the air conditioner, the control precision is improved, and the user experience is improved; when the humidity of an individual position or a part of positions is too high, condensation is about to generate or is generated, at the moment, besides the swing of the swing blade, the speed reduction operation of the fan is further controlled and/or the frequency reduction operation of the compressor is controlled, the condensation generated at a plurality of positions can be prevented in a short time, the action frequency of the fan and the compressor is shortened, and the user experience is further improved.
It should be noted that, although the first direction is a vertical direction and the second direction is a horizontal direction in the present embodiment, this is not intended to limit the scope of the present invention, and it can be understood by those skilled in the art that the first direction and the second direction may be other directions related to the outlet 2 as long as the directions can correspond to the swing direction of the swing blade, for example, the first direction may also be a horizontal direction of the swing blade corresponding to horizontal swing, the second direction may also be a vertical direction of the swing blade corresponding to vertical swing, and so on. Similarly, although the liquid sensor in the present embodiment is described as a humidity sensor, it is obvious that other electrical components may be used instead of the liquid sensor, as long as the electrical components can detect the ambient humidity, for example, the liquid sensor may also be a temperature and humidity sensor. Although the installation position of the humidity sensor is not specifically described, this does not mean that the present invention cannot be implemented, and on the contrary, when implementing the present invention, a person skilled in the art may install the specific position of the humidity sensor based on a specific application scenario as long as the position can detect the humidity at each position of the outlet 2. For example, the humidity sensor is disposed at the outlet 2 or on the housing 1 inside the outlet 2.
In addition, in the present embodiment, the functional component refers to a component that enables the air conditioner to perform some specific functions, for example, the functional component may be a compressor that performs refrigerant flow, a fan that performs indoor air flow, or an outdoor fan that performs outdoor air flow. For setting the humidity threshold, a person skilled in the art can reasonably set the humidity threshold corresponding to each humidity sensor based on the setting position of the humidity sensor and the difference of the condensation state. For example, the humidity value at the position where the humidity sensor is located just before or when condensation has occurred may be set as the humidity threshold, or the humidity at the position where condensation is about to occur may be set as the humidity threshold. For example, the humidity threshold value may be set lower at a position where dew condensation is likely to occur than at other positions, and all the positions may be set to one humidity threshold value. Similarly, the setting manner of the first reference difference and the second reference difference may be similar to the setting manner of the humidity threshold, as long as the condition that the first reference difference is smaller than the second reference difference is ensured, and details are not repeated herein.
It should be noted that although the control unit of the air conditioner is not described in the present embodiment, it can be understood by those skilled in the art that such a control unit may physically be a control chip disposed in the indoor unit, may be a controller specially used for executing the method of the present invention, or may be a functional module or a functional unit of a general controller.
Referring to fig. 1 to 4, in a possible implementation, step S400 may further include:
1.1) when the difference between the humidity value acquired by one of the first sensor 21 and the second sensor 22 and the corresponding humidity threshold value is greater than the corresponding first reference difference and smaller than the second reference difference, controlling the first swing blade 31 to swing towards the other sensor. For example, the control unit of the air conditioner calculates that the difference between the humidity value acquired by the first sensor 21 and the humidity threshold is greater than the corresponding first reference difference and smaller than the second reference difference, and the difference between the humidity value acquired by the second sensor 22 and the humidity threshold is smaller than the corresponding first reference difference, which proves that condensation or small-area condensation occurs at the air outlet 2 at the position of the first sensor 21 soon, and at this time, the control unit controls the first swing vane 31 to swing towards the second sensor 22, that is, controls the first swing vane 31 to swing downwards, so that the air conditioner blows air downwards, so that the temperature at the position of the first sensor 21 is indirectly increased on the premise of not affecting the operation effect of the air conditioner, and the condensation at the air outlet 2 at the position of the first sensor 21 is prevented.
1.2) when the difference value between the humidity value acquired by one of the first sensor 21 and the second sensor 22 and the corresponding humidity threshold value is larger than the corresponding second reference difference value, controlling the first swing blade 31 to swing towards the other sensor, and controlling the compressor to reduce the first set frequency. For example, the control unit of the air conditioner calculates that the difference between the humidity value acquired by the first sensor 21 and the humidity threshold is greater than the corresponding second reference difference, and the difference between the humidity value acquired by the second sensor 22 and the humidity threshold is smaller than the corresponding first reference difference, which proves that condensation is about to occur or condensation with a larger area occurs at the air outlet 2 at the position of the first sensor 21, which is more urgent than the former case, at this time, the control unit controls the first swing vane 31 to swing towards the second sensor 22, that is, controls the first swing vane 31 to swing downwards, so that the air conditioner blows air downwards, so as to indirectly improve the temperature at the position of the first sensor 21, and simultaneously controls the compressor to reduce the first set frequency, for example, the frequency of the compressor is reduced by 10-20% (the specific value or proportion can be adjusted based on experiments or experiences), the temperature of the first sensor 21 is directly increased, so that the condensation at the air outlet 2 where the first sensor 21 is located can be quickly and effectively prevented on the premise that the operation effect of the air conditioner is not affected as much as possible.
2.1) when the difference between the humidity value acquired by one of the third sensor 23 and the fourth sensor 24 and the corresponding humidity threshold value is greater than the corresponding first reference difference and smaller than the second reference difference, controlling the second swing vane 32 to swing towards the other sensor. Similarly to the first case, the control unit of the air conditioner calculates that the difference between the humidity value acquired by at least one of the two third sensors 23 and the humidity threshold is greater than the corresponding first reference difference and smaller than the second reference difference, and the difference between the humidity value acquired by the two fourth sensors 24 and the humidity threshold is smaller than the corresponding first reference difference, which proves that the air outlet 2 at the position of the third sensor 23 will condense or has already generated small-area condensation soon, and at this time, the control unit controls the second swing vane 32 to swing towards the fourth sensor 24, i.e., controls the second swing vane 32 to swing towards the right, so that the air conditioner blows air towards the right, so that the temperature at the third sensor 23 is indirectly increased on the premise of not affecting the operation effect of the air conditioner, and the generation of condensation at the air outlet 2 at the position of the third sensor 23 is prevented.
2.2) when the difference value between the humidity value acquired by one of the third sensor 23 and the fourth sensor 24 and the corresponding humidity threshold value is larger than the corresponding second reference difference value, controlling the second swing blade 32 to swing towards the other sensor, and controlling the compressor to reduce the second set frequency. Similarly to the first case, the control unit of the air conditioner calculates that the difference between the humidity value and the humidity threshold value acquired by at least one of the two third sensors 23 is greater than the corresponding second reference difference, and the difference between the humidity value and the humidity threshold value acquired by the two fourth sensors 24 is smaller than the corresponding first reference difference, which proves that condensation is about to occur or a large area of condensation is already generated at the air outlet 2 where the third sensor 23 is located, at this time, the control unit controls the second swing vane 32 to swing towards the fourth sensor 24, i.e. controls the second swing vane 32 to swing towards the right, so that the air conditioner blows air towards the right, so as to indirectly increase the temperature at the third sensor 23, and simultaneously controls the compressor to reduce the second set frequency, for example, the frequency of the compressor is reduced by 10-20%, the temperature at the third sensor 23 is directly increased, so that the operation effect of the air conditioner is not affected as much as possible, the generation of condensation at the air outlet 2 where the third sensor 23 is located is quickly and effectively prevented.
3.1) when the difference between the humidity values acquired by all the sensors corresponding to any one of the upper area and the lower area of the air outlet 2 and the corresponding humidity threshold is greater than the corresponding first reference difference and smaller than the second reference difference, controlling the first swing blade 31 to swing towards the other area, and/or controlling the fan corresponding to the area to run at a reduced speed. For example, when the differences between the humidity values detected by the first sensor 21, the third sensor 23, and the fourth sensor 24 in the upper region of the outlet 2 and the humidity threshold value are all greater than the corresponding first reference difference and less than the second reference difference, and the differences between the humidity values detected by the second sensor 22, the third sensor 23, and the fourth sensor 24 in the lower region and the humidity threshold value are all less than the corresponding first reference difference, it is proved that condensation will occur or small-area condensation has already occurred in the upper region of the outlet 2 in the near future. At this moment, the control unit controls the first swing blade 31 to swing towards the direction of the lower area, namely, the air conditioner is controlled to blow air downwards, so that the temperature of the upper area is indirectly improved, meanwhile, the control module can also control the fan in the upper area to run at a reduced speed, and the fan in the lower area to run as normal, so that the temperature of the air blown out of the upper area is directly improved, and in addition, the control on the swing direction of the first swing blade 31 can quickly prevent the condensation of the upper area in a short time, reduce the influence on the operation effect of the air conditioner as much as possible, shorten the action frequency of the fan and the compressor, and improve the user experience.
And 3.2) when the difference values between the humidity values acquired by all the sensors corresponding to any one of the upper area and the lower area of the air outlet 2 and the corresponding humidity threshold values are larger than the corresponding second reference difference values, controlling the first swing blade 31 to swing towards the other area, and/or controlling the fan corresponding to the area to run at a reduced speed, and/or controlling the compressor to reduce a fifth set frequency. For example, when the humidity values detected by the first sensor 21, the third sensor 23 and the fourth sensor 24 in the upper area of the outlet 2 and the humidity threshold value are all greater than the corresponding second reference difference value, and the humidity values detected by the second sensor 22, the third sensor 23 and the fourth sensor 24 in the lower area and the humidity threshold value are all less than the corresponding first reference difference value, it is proved that condensation is about to occur or a large area of condensation has occurred in the upper area of the outlet 2. At this moment, the control unit controls the first swing blade 31 to swing towards the direction of the lower area, namely, the air conditioner is controlled to blow air downwards, so that the temperature of the upper area is indirectly increased, meanwhile, the control module also controls the fan in the upper area to run at a reduced speed, the fan in the lower area to run as normal, and controls the compressor to reduce the fifth set frequency, so that the temperature of the air blown out of the upper area is directly increased, and in addition, the control on the swing direction of the first swing blade 31 can quickly prevent the upper area from being condensed in a short time, the influence on the operation effect of the air conditioner is reduced as much as possible, the action frequency of the fan and the compressor is shortened, and the user experience is improved. As a possible embodiment, the fifth setting frequency may be determined based on the first setting frequency and/or the second setting frequency, for example, the fifth setting frequency may be obtained based on the following formula:
in the formula (1), f5For the fifth setting frequency, f1For a first set frequency, f2The second set frequency.
Of course, the above formula is only an example of the calculation method of the fifth setting frequency, and those skilled in the art may determine the specific value of the fifth setting frequency based on other formulas or corresponding relations, such as determining based on only the first setting frequency or the second setting frequency.
4) And when the difference values of the humidity values acquired by all the humidity sensors and the corresponding humidity threshold values are larger than the corresponding second reference difference values, controlling the fan and/or the compressor to stop running, and controlling the air conditioner to send out a fault prompt. When the difference between the humidity values detected by all the sensors and the corresponding humidity thresholds is greater than the corresponding second reference difference, it is proved that the whole air outlet 2 is likely to be subjected to large-area condensation or serious condensation at the moment, or the humidity sensors are likely to break down, the service life of the air conditioner is ensured at the moment, and safety accidents are prevented, the control unit of the air conditioner can send out fault prompts, such as that the air conditioner sends out audible and visual alarms, a display screen of the air conditioner sends out text messages, the control unit sends out fault notifications to a mobile terminal of a user and a cloud end of a service provider through a network, and the user is prompted to clear the condensation at the air outlet 2 of the air conditioner, and/or the user is prompted to check whether the air conditioner service environment or the air conditioner operation state is abnormal, and/or the user is prompted to timely notify the after-sale processing when the.
It should be noted that the above embodiments are only used for illustrating the principle of the present invention, and are not intended to limit the protection scope of the present invention, and those skilled in the art can adjust the above method so that it can be applied to more specific application scenarios without departing from the principle of the present invention.
For example, in an alternative embodiment, in addition to calculating the difference between the humidity value and the corresponding humidity threshold value and comparing the difference with the reference difference, a method of directly comparing the humidity value with the corresponding humidity threshold value may also be adopted, such as setting a first humidity threshold value and a second humidity threshold value, and making the first humidity threshold value smaller than the second humidity threshold value, at this time, by comparing the humidity value collected by the humidity sensor with the first humidity threshold value and the second humidity threshold value respectively, the method of the present invention may also be implemented.
For another example, in another alternative embodiment, the setting position, the setting number of the humidity sensors, and the setting position and the number of the fans may be adjusted, and the corresponding control method may be adjusted by fine adjustment. For example, when the fan is only provided with one fan, the air outlet 2 may be only provided with four humidity sensors, the first sensor 21 and the second sensor 22 are respectively disposed on the upper side and the lower side of the air outlet 2, and the third sensor 23 and the fourth sensor 24 are respectively disposed on the left side and the right side of the air outlet 2, at this time, if the difference between the humidity values acquired by the first sensor 21 and the second sensor 22 and the corresponding humidity thresholds is greater than the second reference difference, and the difference between the humidity values acquired by the third sensor 23 and the fourth sensor 24 and the corresponding humidity thresholds is less than the first reference difference, the fan may be controlled to operate at a reduced speed, and/or the compressor is controlled to reduce a third set frequency, so as to increase an outlet air temperature and prevent condensation. Similarly, if the difference between the humidity values obtained by the third sensor 23 and the fourth sensor 24 and the corresponding humidity threshold values is greater than the second reference difference, and the difference between the humidity values obtained by the first sensor 21 and the second sensor 22 and the corresponding humidity threshold values is less than the first reference difference, the fan may be controlled to operate at a reduced speed, and/or the compressor may be controlled to reduce the fourth setting frequency, so as to increase the outlet air temperature and prevent condensation. In a similar manner to the determination of the fifth setting frequency, the determination method of the third setting frequency and the fourth setting frequency may be based on the following formulas:
in the formulas (2) and (3), f3For the third set frequency, f4The fourth setting frequency.
Further, if the difference values between the humidity values acquired by the first sensor 21, the third sensor 23 and the fourth sensor 24 and the corresponding humidity threshold values are all greater than the second reference difference value, and only the difference value between the humidity value acquired by the second sensor 22 and the corresponding humidity threshold value is smaller than the first reference difference value, at this time, the first swing blade 31 may be controlled to swing downward, that is, the air conditioner is controlled to blow downward, and the fan is controlled to run at a reduced speed, and/or the compressor is controlled to reduce the sixth set frequency, so as to increase the outlet air temperature, prevent condensation from occurring, and shorten the operation frequency of the fan and the compressor. The determination manner of the sixth setting frequency is similar to that of the fifth setting frequency, and is not described herein again.
For another example, the first swing vane 31 and/or the second swing vane 32 may also be configured as two parts, and each part is configured to be independently rotatable in the upper and lower areas corresponding to the air outlet 2, so that when a difference between humidity values collected by a single sensor located in different directions in a certain area and a corresponding humidity threshold is greater than a first reference difference and smaller than a second reference difference, the corresponding part of the swing vanes is controlled to swing independently, thereby rapidly increasing the temperature of the specific area and further improving the control accuracy of the method.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
