Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.
The control method or the control system for the fresh air machine provided by the embodiment of the invention is suitable for the fresh air machine with two working modes, wherein the two working modes are a fresh air mode and an internal circulation mode, the fresh air mode is a known working mode of the fresh air machine or a fresh air system, and the internal circulation mode is a working mode for purifying indoor air. For example, a fresh air inlet and an internal circulation air inlet can be arranged in the fresh air machine, when the fresh air machine is controlled to operate in an internal circulation mode, the fresh air inlet can be controlled to be closed, and the internal circulation air inlet is controlled to be opened so that indoor air enters the fresh air machine to be purified, when the fresh air machine is controlled to operate in the fresh air mode, the internal circulation air inlet can be controlled to be closed, and the external circulation air inlet can be controlled to be closed so that outdoor air enters the fresh air machine to be purified. The purification efficiency of the fresh air machine is inversely proportional to the concentration value of PM2.5 in the air and inversely proportional to the wind speed of the fan of the fresh air machine.
Fig. 1 shows a flow chart of a control method for a fresh air machine in a first embodiment. As shown in fig. 1, an embodiment of the present invention provides a control method for a fresh air machine, where the control method for a fresh air machine in this embodiment may include the following steps:
in step S10, a first concentration value of indoor air PM2.5 is measured.
Step S10 may be performed using a PM2.5 measurement device, which may alternatively be a PM2.5 sensor or a PM2.5 detector, or the like. The PM2.5 measuring device can be arranged at one end of the fresh air fan, and when the fresh air fan is started, the PM2.5 measuring device is firstly controlled to work. When the new fan is not started, outdoor air enters the room through the new fan and passes through resistance components such as a front air channel structure, on the premise that the fan is not driven, the outdoor air is difficult to diffuse indoors through the new fan, the indoor air is relatively closed and poor in mobility, furthermore, when the new fan is started, the PM2.5 measuring device works firstly, the new fan does not start to introduce the outdoor air, therefore, the air around the PM2.5 measuring device is the indoor air at the moment, and the measured PM2.5 value is the concentration value of PM2.5 in the indoor air. Then, under the condition that the fan of the fresh air fan is turned on, the purified outdoor air or indoor air can smoothly enter the room, and the air flowing near the PM2.5 measuring device is the purified indoor or outdoor air at the moment, namely, under the condition that the fresh air fan works in an inner circulation mode, the PM2.5 value measured by the PM2.5 measuring device is the content of PM2.5 in the indoor air purified by the fresh air fan; under the condition that the fresh air fan works in a fresh air mode, the PM2.5 value measured by the PM2.5 measuring device is the concentration value of PM2.5 in outdoor air purified by the fresh air fan.
The content of PM2.5 in the air is generally not more than 600 mu g/m3Therefore, alternatively, a detection range of 0 to 600. mu.g/m can be selected3It can be understood that the PM2.5 measuring device of (1) can also be selected according to actual needs, and has other detection ranges.
When a user turns on a fresh air fan, the PM2.5 measuring device firstly works, the PM2.5 measuring device firstly detects a concentration value of the current indoor air PM2.5, and the concentration value is recorded as a first concentration value in all the embodiments of the present invention.
Step S20, comparing the first concentration value with a first threshold value. In all embodiments of the present invention, the first threshold may be preset to any suitable value according to actual conditions, and preferably may be set to 100 μ g/m3Since the concentration value of PM2.5 exceeds 100. mu.g/m3The air (2) is polluted air and is not beneficial to the health condition of human bodies.
If the first concentration value is greater than the first threshold value, step S30 may be executed to control the new air blower to operate in an inner loop mode.
The first concentration value greater than the first threshold value indicates that the concentration value of PM2.5 in the indoor air is high, and the indoor air needs to be purified, and this may be the case because the concentration value of PM2.5 in the outdoor air is too high, and the concentration value of PM2.5 in the indoor air is high because the outdoor air with too high PM2.5 concentration enters the room, and step S30 may be executed to circularly purify the indoor air. Under the condition that the fresh air fan works in an inner circulation mode, the fan of the fresh air fan can be controlled to operate at any gear.
And in the case that the first concentration value is not greater than the first threshold value, executing a step S40, and controlling the fresh air fan to operate in a fresh air mode. The first concentration value is not greater than the first threshold value, which indicates that the indoor air is good, and the indoor air does not need to be purified, so that the fresh air fan can be controlled to operate in a fresh air mode instead of an internal circulation mode, so that the outdoor air is purified, and the purified air is input indoors. Optionally, in a case where the new air blower operates in the new air mode, the fan of the new air blower may be controlled to operate at a fixed air speed, or the fan of the new air blower may be controlled to operate at different air speeds according to different ranges in which the measured first concentration value is located.
In this embodiment, when new fan was opened, measure indoor air PM 2.5's first concentration value to come intelligent control according to first concentration value new fan's operational mode, thereby can realize accurate quick regulation new fan's purifying effect again.
Fig. 2 shows a flow chart of a control method for a fresh air machine in a second embodiment. As shown in fig. 2, based on the first embodiment, in the case that the fresh air machine operates in the fresh air mode, the control method for the fresh air machine according to the embodiment of the present invention may further include the following steps:
and step S41, controlling the fan of the fresh air machine to run at a low gear under the condition that the first concentration value is in a first concentration range. Wherein, when the fan of the new fan runs at a low-speed gear, the range of the generated air volume is 20-30m3/h。
Here, the first concentration range is a relatively high concentration range, and for example, the first concentration range may be set to 60 μ g/m3To 100. mu.g/m3Including an end point of 60 μ g/m3And 100. mu.g/m3I.e., when 60. mu.g/m3The first concentration value is less than or equal to 100 mu g/m3In this case, the fan of the fresh air machine may be controlled to operate at a low gear, and the purification efficiency of the fresh air machine is inversely proportional to the fan speed of the fresh air machine, so that the fan may be set to operate at the low gear in a case where the first concentration value is in the relatively high first concentration range.
Step S42, controlling the fan of the fresh air fan to operate at a medium-speed gear under the condition that the first concentration value is in a second concentration rangeAnd (6) rows. Wherein, when the fresh air fan runs at a medium speed, the range of the generated air volume is 30-40m3/h。
Here, the second concentration range is a concentration range lower than the first concentration range, that is, the maximum value of the second concentration range is smaller than the maximum value of the first concentration range, and for example, the second concentration range may be set to 30 μ g/m3To 60. mu.g/m3Including an end point of 30 μ g/m3While not including the end point 60. mu.g/m3I.e., when 30. mu.g/m3The first concentration value is less than or equal to 60 mu g/m3In time, the fan of the fresh air machine can be controlled to run at a medium-speed gear.
And step S43, controlling the fan of the fresh air machine to run at a high-speed gear under the condition that the first concentration value is in a third concentration range. Wherein, when the fresh air fan runs at a high-speed gear, the range of the generated air volume is 40-50m3/h。
Here, the third concentration range is a concentration range lower than the second concentration range, that is, the maximum value of the third concentration range is smaller than the maximum value of the second concentration range, and for example, the second concentration range may be set to 0 μ g/m3To 30. mu.g/m3Including the end point 0. mu.g/m3Not including the end point 30. mu.g/m3I.e., when 0. mu.g/m3The first concentration value is less than or equal to 30 mu g/m3In time, the fan of the fresh air machine can be controlled to run at a high-speed gear.
In the embodiment, the rotating speed of the fan is further controlled according to the range of the first concentration value, so that the low-rotating-speed operation of the fan is controlled under the condition of relatively high concentration of PM2.5, and the high-rotating-speed operation of the fan is controlled under the condition of relatively low concentration of PM2.5, thereby ensuring that the fresh air introduced into the room is purified to the maximum extent.
The second embodiment is an optional embodiment, and when the fan of the fresh air machine only has one gear, and when the fresh air machine operates in the fresh air mode, the fan of the fresh air machine operates only in the gear.
Fig. 3 shows a flow chart of a control method for a fresh air machine in a third embodiment. As shown in fig. 3, based on the first embodiment or the second embodiment, when the fresh air machine operates in the fresh air mode, the control method for the fresh air machine according to the embodiment of the present invention may further include the following steps:
step S50 measures a second concentration value of the purified outdoor air PM 2.5. Under the condition that the fresh air fan operates in a fresh air mode, the air purified by the fresh air fan is outdoor air, and the concentration value of the purified outdoor air PM2.5 measured by the PM2.5 measuring device is referred to as a second concentration value.
Step S60, comparing the second concentration value with the first threshold value.
In the case that the second concentration value is greater than the first threshold value, it may be considered that the concentration of PM2.5 in the outdoor air is too high, so that the air after purification still contains high concentration of PM2.5, or the purification may be incomplete due to a failure of the purification device of the fresh air blower. In this case, step S30 may be executed to control the new air blower to operate in the inner circulation mode.
And under the condition that the second concentration value is not greater than the first threshold value, the fresh air fan is indicated to purify completely or the concentration of PM2.5 of outdoor air is low, so that the fresh air fan can be controlled to continue to operate in a fresh air mode.
Fig. 4 shows a flow chart of a control method for a fresh air machine in the fourth embodiment. As shown in fig. 3, based on the first embodiment, the second embodiment, or the third embodiment, when the fresh air machine operates in the internal circulation mode, the control method for the fresh air machine according to the embodiment of the present invention may further include the following steps:
in step S70, a third concentration value of the purified indoor air PM2.5 is measured. When the fresh air fan operates in an internal circulation mode, the air purified by the fresh air fan is indoor air, and the concentration value of the purified indoor air PM2.5 measured by the PM2.5 measuring device is referred to as a third concentration value.
Step S80, comparing the third concentration value with a second threshold value. All in the inventionIn the embodiment, the second threshold may be preset to any suitable value, and preferably may be set to 10 μ g/m3。
When the third concentration value is smaller than the second threshold value, it indicates that the indoor air has been purified well, and at this time, step S40 may be executed to control the fresh air blower to operate in a fresh air mode.
And if the third concentration value is not less than the second threshold value, indicating that the indoor air needs to be further purified, and continuing to execute step S30 to control the new fan to operate in an inner circulation mode.
In the operation process of the fresh air fan, the concentration value of PM2.5 in the purified air is detected in real time, and the operation mode of the fresh air fan is controlled according to the concentration value, so that the condition that the air entering the room from the fresh air fan has the PM2.5 with lower concentration can be ensured.
Further, the control method for the fresh air machine provided by the embodiment of the invention further comprises the following steps: and sending out a prompt when the first concentration value is smaller than a third threshold value.
In all embodiments of the present invention, the third threshold may be preset to any suitable value, and preferably may be set to 10 μ g/m3. And under the condition that the first concentration value is smaller than the third threshold value, if the current outdoor air quality is considered to be excellent, sending a prompt to a user so as to prompt the user not to start a fresh air machine. Optionally, the control device of the fresh air machine may also control the purification module of the fresh air machine to be turned off to save the electric energy when the first concentration value is smaller than the third threshold value. Alternatively, the prompting may be performed by any of the well-known prompting devices.

The PM2.5 measurement device 51 may alternatively be a PM2.5 sensor, a PM2.5 detector, or the like. Wherein the first threshold value may preferably be set to 100 μ g/m3. When the new fan is opened, measure indoor air PM 2.5's first concentration value to come intelligent control according to first concentration value the operational mode of new fan, thereby can realize accurate quick regulation new fan's purifying effect again.
