Air conditioning equipment such as a fresh air machine and an air conditioner can adjust parameters such as temperature, humidity and carbon dioxide concentration of an indoor environment, and the parameters are related to air quality or comfort, so that the air conditioning equipment becomes an electric appliance which is unavailable in life. Air conditioner adjusting device can enter into indoorly from outdoor introduction new trend to accomplish the renewal of room air, improve the new freshness of room air, the new trend gets into indoor in-process and can carry some impurity, consequently need set up the filter screen in the inlet air duct and filter impurity. Among the correlation technique, filter screen and air conditioning equipment leave the factory and go to past independent packing, assembles again when the user installs, nevertheless often appears neglecting the filter screen installation and lead to can't carrying out filterable problem to new trend impurity.
In a first aspect, at least one embodiment of the present disclosure provides a method for detecting a filter screen, please refer to fig. 1, which illustrates a flow of the method, including step S101 and step S103.
The filter screen detection method is applied to controllers in air conditioning equipment such as an air conditioner and a fresh air fan, and the controllers can be applied to a main control board of the air conditioning equipment or are special MCU (micro controller Unit) on the main control board. The air conditioning equipment can be provided with an air inlet channel, and a fan and a filter screen are arranged in the air inlet channel. One end of the air inlet channel faces the outdoor environment, and the other end of the air inlet channel faces the indoor environment, so that fresh air can be introduced into the room from the outside. Before the air conditioning equipment leaves the factory, the filter screen can be installed in the air inlet channel in a packaged mode. The filter screen can filter impurities in fresh air; the packing can be for the plastic packaging bag, and the plastic packaging bag can be for sealing the wrapping bag, can be vacuum state in the wrapping bag moreover to can reduce the wrapping bag and to the increase of filter screen volume, thereby be convenient for the wrapping bag to install in corresponding the position with the filter screen simultaneously.
Before the air conditioning equipment is installed and used, the filter screen is in the package, and is the same as the independently packaged filter screen, so that the air conditioning equipment is not influenced by the environment and the performance is not reduced; after the air conditioning equipment is installed, the package outside the filter screen needs to be removed before the air conditioning equipment is ready for use, so that the air conditioning equipment can be ventilated normally. Along with the service life extension of filter screen, the filter screen can appear shutoff, damaged scheduling problem, needs clean.
In step S101, a current signal of the fan is acquired.
The current signal may be a current value.
Air conditioning equipment when control fan rotates, can be according to the gas flow rate in the inlet air duct for the fan power supply, if need increase the gas flow rate promptly, then increase the power supply to can cause the increase of current value, if need reduce the gas flow rate, then reduce the power supply, thereby can cause the reduction of current value. Therefore, if the electrical values when the same gas flow rate is reached are different, the air inlet channel is caused by different smoothness degrees, namely caused by different smoothness degrees of the filter screen.
In one example, the main control board of the air conditioning equipment can be provided with a detection circuit, so that the current value of a fan of the air conditioning equipment can be detected, and an electrical signal can be amplified in the detection process, so that the accuracy of detection is increased. Specifically, the detection circuit can be arranged on a communication line between the main control board and the fan, so that the detection circuit can acquire a control instruction of the main control board to the fan in real time and acquire a current value of the fan.
In another example, a controller for executing the method and a hall sensor are installed on a main control board of the air conditioning device, the hall sensor is used for detecting the current of the fan, and the hall sensor is in communication connection with the controller. Therefore, in the step, the controller can acquire the current value of the fan acquired by the Hall sensor.
In step S102, status information of the filter screen is determined according to the current signal of the fan, where the status information is used to indicate whether the filter screen installed in the air intake channel has a package.
According to the analysis in step S101, the magnitude of the current value can be used to represent the unobstructed degree of the filter screen, and different unobstructed degrees correspond to different states of the filter screen, so that the state information of the filter screen can be determined through the current signal.
The state of the filter screen can be a normal state and a state to be unsealed, the normal state represents that the smoothness degree of the filter screen is normal, namely the filter screen is not provided with a package; the state to be unsealed shows that the filter screen is in a complete plugging state, namely the filter screen is provided with a package and is completely plugged by the package.
The above-mentioned state to be unsealed is caused by that the filter screen in this embodiment is installed in a packaged state at a corresponding position of the air conditioning equipment before leaving the factory, and the package is not removed after the air conditioning equipment is installed and used. Therefore, the embodiment can detect that the filter screen is in a normal state or a state to be unsealed, and can be used as a detection method for detecting whether the filter screen package is detached before being installed and used. Preferably, the method is only operated after the first three power-on times after the air conditioning apparatus is installed and used.
In one example, in the case that the value of the current signal is smaller than a preset first threshold value, the state information of the filter screen is determined to be a normal state, and the normal state is used for indicating that the filter screen installed in the air inlet channel is not provided with a package; and under the condition that the value of the current signal is greater than a preset second threshold value, determining that the state information of the filter screen is a to-be-unsealed state, wherein the to-be-unsealed state is used for indicating that the filter screen installed in the air inlet channel is provided with a package. Wherein the first threshold and the second threshold may be preset empirically.
In step S103, a prompt operation is performed according to the state information of the filter screen.
In one example, in the case that the state information of the filter screen is in a normal state, a prompt operation for instructing a processing measure used normally is performed; and under the condition that the state information of the filter screen is in a state to be unsealed, prompting operation for indicating treatment measures for removing the package of the filter screen is carried out.
Optionally, when the prompt operation is performed, the prompt may be performed in any one or more of the following manners: controlling a buzzer or a loudspeaker to give out prompt sound; generating a prompt message and sending the prompt message to a mobile terminal bound by a user in advance through a communication module; and generating a prompt message and displaying the prompt message on a display screen of the air conditioning equipment.
The buzzer or the loudspeaker can be arranged on a main control panel of the air conditioning equipment and is in communication connection with the controller, so that the controller can control the buzzer or the loudspeaker to give out prompt tones. The communication module can also be arranged on a main control board of the air conditioning equipment and is in communication connection with the controller, so that the controller can control the communication module to send the prompt message. Since the controller is disposed on the main control board, the main control board can display the prompt message generated by the controller on the display screen of the air conditioning equipment.
According to the air conditioning equipment, the current signal of the fan of the air conditioning equipment is acquired, the state information of the filter screen is determined according to the current signal of the fan, and finally the prompt operation is carried out according to the state information of the filter screen. Because the state information is used for indicating whether the filter screen installed in the air inlet channel is provided with the package or not, the prompt operation carried out according to the state information can ensure that a user determines whether the filter screen is provided with the package or not, and then corresponding treatment measures can be taken for the filter screen, so that the filter screen is in better state information; and air conditioning equipment's air inlet channel has set up the filter screen in addition, can avoid because of neglecting the unable filterable problem to new trend impurity that the installation of filter screen leads to, the filter screen still has the packing before dispatching from the factory, consequently before air conditioning equipment installs and uses, the filter screen can not be influenced by the environment like independent packing.
In other words, the present disclosure provides an air conditioning equipment with a packaged filter screen installed in advance, and provides a matched filter screen detection method, so that the assembly of the filter screen can be avoided being neglected when the air conditioning equipment is installed, and whether the package of the filter screen is removed can be detected by the detection method, if not removed, the user can be prompted by a prompt message, so that the user can remove the filter screen in time, and the problems that the air cannot enter the air due to the blockage of the filter screen, and even danger is caused are avoided.
In some embodiments of the disclosure, the method can be used for further monitoring the state of the filter screen besides detecting whether the filter screen installed in the air inlet channel is provided with a package, so as to prompt the cleaning work of the filter screen.
Optionally, the state information is further used for indicating whether a filter screen installed in the air intake channel is to be cleaned.
Based on this, when the state information of the filter screen is determined according to the current signal of the fan, the method can further comprise the following steps: and determining the state information of the filter screen as a state to be cleaned under the condition that the value of the current signal is greater than a third threshold and smaller than the second threshold. And when the prompt operation is carried out according to the state information of the filter screen, the following steps can be carried out: and under the condition that the state information of the filter screen is in a state to be cleaned, performing prompt operation for indicating treatment measures for cleaning the filter screen.
The above-mentioned state of waiting to clean is that the filter screen normally uses after the long time, and the jam of impurity to the filter screen causes unobstructed degree to descend and causes. The third threshold may be preset, and the third threshold is greater than the first threshold.
In this embodiment, after air conditioning equipment normally used, can also use detection method to detect the state of filter screen to in time clean when the shutoff appears, thereby avoid the unobstructed degree decline of filter screen.
In some embodiments of the present disclosure, the current signal of the fan of the air conditioning device may be acquired as follows: firstly, controlling the fan to rotate positively, and acquiring a first current signal of the fan; next, controlling the fan to rotate reversely, and acquiring a second current signal of the fan; and finally, determining a current signal of the fan according to the first current signal and the second current signal.
Wherein an average value of the first current signal and the value of the second current signal may be calculated as the value of the current signal of the fan.
The first current signal and the second current signal are respectively obtained through positive and negative rotation of the fan, and then the first current signal and the second current signal are further combined to determine the current signals, so that the problem that the current signal detection is inaccurate due to abnormal rotation in one direction can be avoided, the detection accuracy of the state of the filter screen is improved, and the appropriate degree of processing measures in information is improved.
