Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
CO2Is an important index for detecting indoor air quality, however, CO2During the working process of the sensor, CO can be caused by the attenuation of the luminescent device and the aging deformation of the device shell2Inaccurate sensor readings, therefore CO2The sensor needs to be calibrated once per operating period. CO due to the atmosphere2The concentration is almost a constant value (e.g., about 400), so CO2The reference value for sensor calibration is generally 400, so various calibrations are performed to obtain this accurate reference value.
In the related art, the CO is generally performed by using a software algorithm2Calibration of the sensor, in particular, by software recording the lowest CO over a period of time (e.g., 7 days or more)2The value is taken as CO2Calibration reference value 400 for the sensor. However, if the household CO is used2Ratio of concentration to timeHigher, e.g. the lowest value is always 700, thus for CO2After the sensor is calibrated, 700 will be taken as CO2Reference value of the sensor 400, then, CO2The sensor readings are completely inaccurate.
To promote CO2The accuracy of sensor correction, this disclosure provides a new fan.
Fig. 1 is a schematic structural view of a new fan in the related art according to an exemplary embodiment, and as shown in fig. 1, the new fan includes: fresh air intake 11 and fresh air outlet 12 to and set up at fresh air intake 11 with filter screen 13 and flabellum 14 between the fresh air outlet 12, fresh air intake 11, fresh air outlet 12, filter screen 13 and flabellum 14 constitute new fan work wind channel. When the fan blades 14 rotate, outdoor air can enter the fresh air machine through the fresh air inlet 11, the filter screen 13 filters and purifies the outdoor air entering the fresh air machine, and the filtered and purified outdoor air enters the room through the fresh air outlet 12.
In order to realize the CO alignment by means of a fresh air fan in the disclosure2Calibration of the sensor, on the basis of FIG. 1, CO is set in the fresh air fan2The air duct 15 is detected.
In CO2The detection air duct 15 is respectively provided with a correction air inlet A, a correction air outlet B, a detection air inlet C and CO2And a sensor D.
Wherein the correction air inlet A communicates outdoor air with CO2Inside the detection duct 15, located at the CO2Upstream of sensor D; the correcting air outlet B is positioned at CO2The downstream of the sensor D is communicated with a working air duct of a fresh air fan and CO2Detecting the interior of the air duct; detect tuyere C at CO2Downstream of the sensor D and the sieve 13, and communicating the room air with the CO2Inside the detection duct 15.
When the fresh air fan is used, not only can outdoor air be effectively purified, but also CO can be passed through2Sensor D measures CO in the room air2And may also be on CO2The sensor D performs calibration, specifically:
when it is necessary to treat CO2Sensor with a sensor elementD when correcting, control opens correction wind entry A and correction wind export B to close and detect wind gap C, outdoor air gets into new trend fan working air duct through new trend air intake 11, and at this moment, outdoor air is except getting into indoor through filter screen 13, still can get into CO through correcting wind entry A and get into2The interior of the air duct 15 is detected and then returned to the working air duct of the new fan through the correcting air outlet B, because CO is generated at the moment2The detection duct 15 is filled with outdoor air, so that CO is present2The sensor D measures the CO in the outdoor air2Concentration, so that the CO can be used at this time2In a concentration as CO2Corrected reference value of sensor D, since it is a direct measurement and uses CO in outdoor air2Concentration to correct CO2Sensor D, thereby making the correction result more accurate, and further promoting CO2The exact nature of the sensor D measurement.
Taking the fresh air machine shown in fig. 2 as an example, when the CO2 sensor D needs to be corrected, as shown in fig. 3, the correction air inlet a and the correction air outlet B are controlled to be opened, the detection air inlet C is closed, outdoor air enters the fresh air machine through the fresh air inlet 11, at this time, the outdoor air enters the room through the filter screen 13, enters the CO2 detection air duct 15 through the correction air inlet a, and then returns to the downstream of the filter screen 13 and the fan blades 14 in the fresh air machine working air duct through the correction air outlet B, because the CO2 detects that the air duct 15 is filled with the outdoor air, at this time, the CO2 sensor D is filled with the outdoor air2The sensor D measures the CO in the outdoor air2Concentration, so that the CO can be used at this time2In a concentration as CO2Corrected reference value of sensor D, since it is a direct measurement and uses CO in outdoor air2Concentration to correct CO2Sensor D, thereby making the correction result more accurate, and further promoting CO2The exact nature of the sensor D measurement.
Continuing with the fresh air machine shown in FIG. 2 as an example, when CO is not needed2Sensor D for calibration or CO2After the calibration of sensor D is completed, CO is required to pass through2Sensor D measures CO in the room air2At the time of concentration, as shown in fig. 4, the off correction is controlledAir inlet A and correction air outlet B, and opening detection air inlet C, at the moment, CO2The sensor D can measure indoor CO by detecting indoor air entering from the air inlet C2And (4) concentration.
Continuing with the fresh air machine shown in FIG. 2 as an example, when CO is not needed2When the sensor is corrected, CO does not need to be passed2Sensor for measuring CO in indoor air2At the time of concentration, as shown in fig. 5, the correction wind inlet a, the correction wind outlet B, and the detection wind port C may be closed at the same time.
In the related art, a method for calibrating a dual-channel sensor is also adopted to calibrate the CO2The sensor is calibrated by using a reference channel to correct for the compensation. Although the stability of the dual-channel sensor is greatly improved compared with that of a single-channel sensor, calibration is not completely needed, only the calibration period can be longer (for example, once a year), and in addition, the cost of the dual-channel sensor is almost doubled compared with that of the single-channel sensor. In the present disclosure, a CO is added to the fresh air machine2Detecting air channel in the CO2Introducing fresh air from the outside during sensor calibration, thereby enabling CO2The sensor obtains a completely accurate reference value, and excessive cost is not increased through the improvement of the new fan.
It should be noted that the positioning of the correcting wind outlet B downstream of the screen 13 and the fan blades 14 in fig. 2 to 5 is only an example, and when the correcting wind outlet B is positioned downstream of the screen 13 and the fan blades 14, the CO is not limited thereto2When the sensor D is used for correcting, the correction air inlet A and the correction air outlet B can be controlled to be opened, the detection air port C is closed, at the moment, outdoor air can flow through the correction air outlet B, enter the downstream of the filter screen 13 and the fan blades 14 in the working air duct of the fresh air fan and enter the room through the fresh air outlet 12, and therefore air which is not filtered by the filter screen 13 can enter the room, and in order to achieve the aim of correcting CO2While sensor D corrects for and prevents unfiltered outdoor air from entering the room, in one embodiment, as shown in FIG. 6, correction air outlet B may be located upstream of filter 13 and fan blades 14 in the fresh air fan operating duct, as shown in FIG. 7, when CO is being filtered2When the sensor D is used for correcting, the correction air inlet A and the correction air outlet B are controlled to be opened and the detection air port C is closed, at the moment, the correction air outlet B is positioned at the upper streams of the filter screen 13 and the fan blade 14 in the working air channel of the fresh air fan, so that outdoor air can flow through the correction air outlet B and enter the upper streams of the filter screen 13 and the fan blade 14 in the working air channel of the fresh air fan, at the moment, the outdoor air flowing out of the correction air outlet B can be filtered through the filter screen 13, and then enters the room through the fan blade 14 and the fresh air outlet 12.
The present disclosure provides a new fan, including: fresh air intake and fresh air outlet to and filter screen and the flabellum of setting between fresh air intake and fresh air outlet, fresh air intake, fresh air outlet, filter screen and flabellum constitute new fan work wind channel, still include: CO22Detecting an air duct; CO22CO is respectively arranged in the detection air duct2The device comprises a sensor, a correction air inlet, a correction air outlet and a detection air port; the correcting air inlet is communicated with outdoor air and CO2Detect the inside of the air duct, at the CO2Upstream of the sensor; the wind outlet is located at CO2The downstream of the sensor is communicated with the working air duct of the fresh air fan and CO2Detecting the interior of the air duct; detecting the position of the tuyere at the CO2Downstream of the sensor and the filter screen, and communicating indoor air with CO2And detecting the interior of the air duct. By adding a CO in the fresh air machine2Detecting air passage and passing the CO2Detecting air duct directly adopting outdoor air to carry out CO2Calibration of the sensor, thereby enhancing CO2Accuracy of the calibration reference value of the sensor.
In one embodiment, the calibration air inlet, the calibration air outlet and the detection air port are respectively provided with a valve.
The type of valve is not limited in this disclosure.
Of course, the above-described valve may be provided in at least one of the calibration wind inlet, the calibration wind outlet, and the detection wind port, or in at least two of them.
Fig. 8 is a flowchart illustrating a control method of a fresh air machine according to an exemplary embodiment, where as shown in fig. 8, the method is applied to the fresh air machine according to any of the above embodiments, and includes the following steps S101 to S102:

The technical scheme provided by the embodiment of the disclosure can have the following beneficial effects: detecting whether CO is received2Sensor correction signal, when CO is received2When the sensor corrects the signal, the detection air port is controlled to be closed, and the correction air inlet and the correction air outlet are controlled to be opened, so that CO can be discharged2Sensor for detecting CO in outdoor air2Concentration and using the measured CO in the outdoor air2In a concentration as CO2A calibration reference value for the sensor. When it is necessary to treat CO2When the sensor is used for correction, the detection air port can be controlled to be closed, and the correction air inlet and the correction air outlet are opened, so that outdoor air enters CO2Detect air passage, thus, is located in CO2Detecting CO in an air duct2The sensor can be calibrated directly by using outdoor air, so that CO can be obtained2The sensor value is completely accurate, and the user experience is greatly improved.
In one embodiment, the above method further comprises the following sub-step a 1:
in A1, after acquiring the correction reference value, the control closes the correction wind inlet and the correction wind outlet and opens the detection wind port to make CO2Sensor for detecting CO in indoor air2And (4) concentration.
In the presence of CO2After the sensor calibration is over, i.e. CO2Sensor obtains CO in outdoor air2After the value is reached, the correction air inlet and the correction air outlet can be controlled to be closed, and the detection air port can be controlled to be opened, so that CO can be introduced into the air inlet2Sensor for detecting CO in indoor air2Concentration due to detectionCO in indoor air2Pre concentration to CO2The sensor is calibrated so that the CO is2CO in room air measured by sensor2The concentration value is more accurate.
In one embodiment, the determining to obtain the correction reference value includes the following sub-steps: and when the control time reaches the preset time, determining that the correction reference value is acquired.
Wherein the control time comprises at least one of the following times: and detecting the closing time of the air port, the opening time of the correction air inlet and the opening time of the correction air outlet.
Due to the CO in the outdoor air2Concentration value as CO2Calibration reference value of the sensor, therefore, CO is being performed2When calibrating the sensor, CO2The detection air duct is filled with outdoor air instead of mixed gas of the outdoor air and the indoor air, so that CO is required to be mixed with the indoor air2And detecting that all indoor air remained in the air channel is discharged. In the present disclosure, whether to convert CO into CO is determined by detecting a control time2And detecting that all indoor air remained in the air channel is discharged.
For example: the preset time is 5 minutes, and then, when the closing time of the tuyere is detected to reach 5 minutes, it is determined that CO is to be supplied2Detecting the discharge of all residual indoor air in the air duct, wherein at the moment, CO is discharged2CO measured by sensor2Concentration of CO in outdoor air2And (4) concentration.

In one embodiment, a CO is received2A sensor correction signal comprising the sub-steps of: determining reception of CO when it is detected that a preset correction time point arrives2The sensor corrects the signal.
In practical application, the CO can be triggered manually2Corrective actions of the sensors, for example: physical keys can be preset in the fresh air machine, and when a user presses the physical keys, the user can determine that the physical keys are receivedThe correction signal, of course, may also be set up the virtual key in the APP of the new fan, when the user clicks this virtual option, just confirm that this CO has been received2The sensor corrects the signal. To improve user experience, the detection frequency may be preset for CO2Calibration of the sensor, for example: correcting once in 10 days, and the primary correction time is 10, month and 14 days in 2018, then when the current time is 10, month and 24 days in 2018, determining that the CO is received2The sensor corrects the signal when actively aligning to CO2The sensor is calibrated.
