An air suction port is provided on the outside of the air cleaner case 2 at a position corresponding to the pre-filter 3, and an access door is provided on the outside of the air cleaner case 2 below the control panel 1 at a position corresponding to the needle-like dust collecting unit 4, the deodorizing filter 5, the fan 6, and the power supply box 7, and an air outlet port is provided on the lower portion of the access door. The access door can also be provided with a locking device. A main power switch can be arranged on the side surface of the lower end of the outer part of the box body 2.
Fig. 1 shows a structure diagram of the control panel 1, wherein the control panel 1 is provided with a digital display 11, an automatic mode switch 12, manual mode switches 131, 132, 133 corresponding to the low-speed, medium-speed, and high-speed wind force positions, first indicators 141, 142, 143 corresponding to the pre-filter 3, the needle-shaped dust collecting assembly 4, and the deodorizing filter 5, second indicators 151, 152, 153 corresponding to the low-speed, medium-speed, and high-speed wind force positions, and a power switch 16.
The digital display 11 is specifically a 7-segment LED display, and is configured to display the currently monitored air pollution level through a numerical value. This range is particularly between 000 and 500. In order to monitor the current air pollution level, the air purifier of the present invention is further provided with a dust sensor 17 to monitor PM1.0 and display the monitored value through the digital display 11.
The first indicators 141, 142, and 143 are LED lamps for indicating when the pre-filter 3, the needle-shaped dust collecting unit 4, and the deodorizing filter 5 need to be replaced or cleaned. It can be understood that the air cleaner of the present invention is provided with a timer for determining whether the time required for replacing or cleaning the pre-filter 3, the needle-shaped dust collecting assembly 4 and the deodorizing filter 5 respectively, i.e. whether the time exceeds a predetermined threshold value, so that the corresponding first indicator is turned on to indicate. It should be understood that the time during which the pre-filter 3, the needle-shaped dust collecting unit 4, and the deodorizing filter 5 are stopped is not counted.
Preferably, when the prefilter 3, the needle-like dust collecting unit 4 and the deodorizing filter 5 are near the time of replacement or cleaning, the alarm may be first provided by blinking corresponding to the first indicator.
It is known that for different pollution levels, the fan is required to operate at different wind speeds, and the manual mode switches 131, 132 and 133 correspond to different wind speeds, and the fan operates at a low speed when the manual mode switch 131 is turned on, at a medium speed when the manual mode switch 132 is turned on, and at a high speed when the manual mode switch 133 is turned on. For further intellectualization, the present invention further provides an automatic mode switch 12 to switch the working mode of the fan from manual to automatic, and after switching to automatic mode, a control unit (not shown in the figure) in the air purifier can adjust the wind power gear of the fan according to the air pollution degree when monitoring that the fan is in automatic working mode, so that the fan works at corresponding wind speed. The higher the air pollution value, the higher the wind speed. In addition, the present invention further provides a third indicator 121, specifically an LED lamp, for indicating the automatic mode activation.
For example, when the current air pollution value is judged to be 201-500, the fan is enabled to work at a high speed, and when the air pollution value is 101-200, the fan is enabled to work at a medium speed. Specifically, the switching can be performed by combining the working wind speed of the current fan. This will be explained in detail in the method examples.
In order to make the user know the current wind speed of the fan, the wind speed indicator is provided with second indicators 151, 152 and 153 which respectively correspond to low-speed, medium-speed and high-speed wind gears, the specific second indicator can be an LED lamp, and the current wind speed of the fan is prompted by lighting the LED lamp. For example, when the front fan is operating at a low speed, the second indicator 151 is lit to indicate.
After the pre-filter 3, the needle-shaped dust collecting assembly 4 and the deodorizing filter 5 are replaced or cleaned, the corresponding first indicator needs to be reset, and therefore, the corresponding first indicator can be reset by long pressing the corresponding manual mode switch. For example, long-press manual mode switch 131 may reset first indicator 143, long-press manual mode switch 132 may reset first indicator 142, and long-press manual mode switch 133 may reset first indicator 141. For this purpose, the control unit is further configured to determine a time when each manual mode switch is pressed by the user, and if the time exceeds a set time, determine that the user inputs a command for resetting the corresponding first indicator, and reset the corresponding first indicator accordingly. And if the set time is not exceeded, judging that the command input by the user is the command for setting the wind speed of the fan. The set time may be 10 seconds.
The power switch 16 is used to power on the components on the control panel, and when the main power switch is turned on, the power switch 16 is turned on again to operate the control panel. A fourth indicator 161, specifically an LED lamp, is further provided in the present invention for indicating the on state of the power switch.
Based on the air purifier, the current air pollution level can be displayed in a digital mode, and meanwhile, the replacement or cleaning of various filters is respectively indicated.
Corresponding to the above device, the embodiment of the invention also discloses a working method of the air purifier, which is specifically shown in fig. 3-5.
Fig. 3 shows an initialization procedure of the air cleaner, specifically:
and starting and powering on, initializing a driving program, detecting whether an internal switch exists in the shipment setting, setting the display of the LED after setting a maintenance-allowable mark if the internal switch exists, and directly setting the display of the LED and the digital display 11 if the internal switch does not exist. Specifically, the fourth indicator 161 is set to on, the third indicator 121 and the second indicators 151 to 153 are set to off, and the display of the digital display 11 is set to "___".
After the setting is completed, the previous setting value, which is specifically one of the operation modes of the fan, such as the automatic mode or the manual mode, the replacement time of each filter, and the like, is read out from the storage memory, and the initial value of the operation mode of the fan and the like is set according to the setting value and the flag in the initialization is displayed.
And then judging whether the initial value is wrong or not, if so, setting a wrong sign, displaying 'E-1' by the digital display 11, and setting the working mode of the fan 6 to be a low-speed mode, namely, starting a low-speed working mode, and closing a medium-speed and high-speed working mode. Then, a timer is started and enters a main cycle, specifically, the timer is a 1ms timer in the invention.
If the initial value is correct, setting an error flag in a clearing state, then judging whether the fan is in an automatic mode, if so, setting a lamp 121 to be on, and setting lamps 151-153 to be off, and simultaneously setting the fan to be in a low-speed mode; if the mode is not the automatic mode, whether the mode is the low speed, the medium speed or the high speed in the manual mode is judged in sequence. If the low-speed mode is the manual mode, setting 151 lamps to be on, setting 121, 152-153 lamps to be off, and setting the working mode of the fan 6 to be the low-speed mode; if the mode is the medium speed mode, 152 lamps are turned on, 121, 151 and 153 lamps are turned off, and the working mode of the fan 6 is the medium speed mode; if the mode is the high-speed mode, 153 lamps are set to be on, 121, 151-152 lamps are set to be off, and the working mode of the fan 6 is set to be the high-speed mode. In the judging process, no matter what wind speed mode the fan is in, after the corresponding setting is finished, the system enters the main circulation.
Fig. 4 shows a process of switching wind speeds according to different air pollution levels when a fan is in an automatic operation mode during a main cycle, which includes:
judging whether the current wind speed of the fan is low speed, if so, continuously judging whether the pollution value is between 101 and 200, and if so, switching the wind speed of the fan to be medium speed; if the pollution value is not between 101 and 200, judging whether the pollution value is between 201 and 500, and if the pollution value is between 201 and 500, switching the wind speed of the fan to be high speed. And switching to the medium speed, the high speed or returning to the main program when the pollution value is not between 201 and 500.
If the current wind speed of the fan is not low, continuously judging whether the wind speed is medium, if so, judging whether the pollution value is between 000 and 069, and if so, switching the wind speed of the fan to low; if the pollution value is not between 000 and 069, judging whether the pollution value is between 201 and 500, and if so, switching the wind speed of the fan to a high speed. And switching to low speed, high speed or returning to the main program when the pollution value is not between 201 and 500.
If the current wind speed of the fan is not the medium speed, continuously judging whether the pollution value is between 000 and 069, and if the current wind speed of the fan is between 000 and 069, switching the wind speed of the fan to the low speed; if the pollution value is not between 000 and 069, judging whether the pollution value is between 070 and 159, and if so, switching the wind speed of the fan to the medium speed. Switching to low speed, medium speed or when the contamination value is not between 070-159, returning to the main routine.
The values such as 201-500, 000-069 used for determining the switching wind speed can be changed according to specific situations.
Fig. 5 shows a processing procedure of the 1ms timer, which first reads the states of the switches 131 to 133 and 12, determines whether the switches are simultaneously pressed, and if not, sets the on states of the switches 131 to 133 and 12 and the settings of the long press 1s and the long press 10s in sequence. The long press 1s is an operation for setting the time of replacement. The long press 10s is an operation for maintenance and an operation for setting a replacement time.
If at least two of the switches 131-133 and 12 are simultaneously pressed, the switch press is disabled. It is determined whether the filter has reached a time that is close to the time at which the filter needs cleaning or replacement. When the time of the filter arrives, whether the time exceeds 0.1s is judged, if yes, the notification time exceeds 0.1s, whether the filter is in maintenance is judged, and if yes, the first indicators 141-143 corresponding to the filter are set to flash for prompting. Then, whether the time exceeds 1s is continuously judged, and when the time exceeds 1s, the notification time exceeds 1s, and the using time of the corresponding filter plus 1 is stored in the storage memory. And then, continuously judging whether the filter is in maintenance, if not, sequentially judging whether the service time of the corresponding filter is exceeded, and if so, setting a corresponding first indicator to light for prompting.
After the prompt is performed, whether the corresponding filter is in maintenance or not is judged, if not, but the filter can be maintained, whether the first indicators 141-143 are lighted or not and whether the first indicators 133-131 have long press input or not is judged, and if yes, the corresponding first indicators are lightened. For example, when the 141 lamp is on and the 133 is determined to be pressed for 10s, 141 is off. Meanwhile, the first indicator service time is changed from the initial value to the actual lighting time and is stored.
According to the above process, the method of the present invention comprises the following steps:
initializing, and initially setting the digital display, the first indicator, the working mode of the fan and the timer of the air purifier;
after initialization, if the fan is in an automatic working mode, setting a wind power gear of the fan according to the monitored current air pollution degree; if the fan is in a manual working mode, setting a wind power gear of the fan according to a second instruction input by a user through a manual mode switch; the second indicator is started to indicate when the fan works in the corresponding wind power gear;
after initialization, the timer respectively counts the accumulated use time of the filters and respectively judges whether the accumulated use time exceeds the second preset time corresponding to the timer, and a first indicator corresponding to the filter exceeding the second preset time corresponding to the timer is started to indicate;
after initialization, the digital display displays the current air pollution degree according to the monitoring.
Preferably, the method further comprises:
after initialization, if the time that the user presses the manual mode switch does not exceed the first preset time, the instruction is a second instruction; and if the first instruction exceeds the second instruction, the first instruction is a third instruction, and the first indicator corresponding to the manual mode switch corresponding to the third instruction is controlled to be closed. The first predetermined time may be 10 seconds.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
