Thus, it is possible to provide an air cleaner having an effect that it can be operated.

  Further, the signal from the dirt detecting means is converted and stored as a dirt level value for 7 days in a time series, and the stored dirt level value and the air volume of the blowing means for the next week determined from the stored dirt level. Since the air level of the air blowing means for the next week is controlled in time series by calculating the dirt level value detected from the dirt detecting means by the operation of, the air dirt can be collected efficiently by the operation assuming air dirt. Thus, it is possible to provide an air cleaner having an effect of being able to operate with a leveled life pattern.

  Further, the signal from the dirt detecting means is converted and stored as a dirt level value for 7 days in a time series, and the stored dirt level value and the air volume of the blowing means for the next week determined from the stored dirt level. Since the soil level value detected from the soil detection means by the operation according to the above is calculated and the air volume of the blowing means for the next week is determined and operated in time series, each soil level value is stored for 365 days. In the following year, by correcting the operation pattern of the day from the dirt level value detected on the day of the previous year, it is possible to provide an air cleaner having an effect that the operation can be more suitable for a living scene.

  Further, the signal from the dirt detecting means is converted and stored as a dirt level value for 7 days in a time series, and the stored dirt level value and the air volume of the blowing means for the next week determined from the stored dirt level. As a result of calculating the dirt level value detected from the dirt detection means by the operation according to the above, when the continuous time when the air volume of the driving means becomes zero exceeds a predetermined time, the air volume of the blowing means that operates intermittently is reduced. It is possible to provide an air cleaner having an effect of suppressing excessive driving on a day when there is little dirt.

  Further, the signal from the dirt detecting means is converted and stored as a dirt level value for 7 days in a time series, and the stored dirt level value and the air volume of the blowing means for the next week determined from the stored dirt level. As a result of calculating the dirt level value detected from the dirt detection means by the operation according to the above, when the continuous time when the air volume of the driving means becomes zero exceeds a predetermined time, the stop time of the intermittent operation is extended. It is possible to provide an air cleaner having an effect of suppressing excessive driving on a day when there is little dirt.

  Further, the signal from the dirt detecting means is converted and stored as a dirt level value for 7 days in a time series, and the stored dirt level value and the air volume of the blowing means for the next week determined from the stored dirt level. As a result of calculating the dirt level value detected from the dirt detection means by the operation by the operation, it is judged whether the stored dirt level value is due to the dust detection part or the gas detection part, and the operation pattern of the blowing means is changed Thus, it is possible to provide an air purifier having an effect of efficiently cleaning air dirt having different qualities.

  Moreover, since the operation pattern of the air blowing means is changed on the basis of the dirt storage data for one year, assuming the air pollution that occurs due to seasonal factors, the air purifier has the effect of being able to operate more suitable for the life scene Can provide.

  In addition, the storage data is not updated on the day when air pollution deviating from the normal life rhythm is detected on the basis of the dirt storage data every seven days, so that the stored driving pattern is not disturbed. It is possible to provide an air purifier having an effect of being able to operate suitable for a basic life scene.

  In addition, since the air volume calculated based on the data every 7 days and determined in time series can be temporarily stopped by the switch operation, useless operation can be suppressed even in response to a sudden change in the indoor environment. It is possible to provide an air purifier that is effective.

  In addition, since the air dirt level value detected by the dirt detecting means can be determined to be invalid by the switch operation, even if a good odor is generated, the air cleaning is effective in that it can live in a comfortable environment without performing the removal operation. Can provide a machine.

  According to the first aspect of the present invention, there is provided an air inlet provided in the main body, a purifying means for purifying dirty air sucked from the air inlet, an air blowing means for ventilating the purifying means, and a dirt component in the air. And a control unit for controlling the air volume of the blower means based on a detection signal from the dirt detection unit. The control unit converts a signal from the dirt detection unit to obtain a dirt level value. 7 days are stored in time series, and the air volume of the blowing means for the next week determined from the stored dirt level value is controlled in time series. Weekdays from Monday to Friday and Saturday Sunday By memorizing the difference in the daily life pattern from the holiday, the daily life driving pattern is not disturbed by the holiday life pattern.

  Further, the control unit converts the signal from the dirt detecting means and stores it for 7 days in a time series as a dirt level value, and the next week determined from the stored dirt level value and the stored dirt level. The air flow of the blowing means is calculated in a time-series manner by calculating the dirt level value detected from the dirt detecting means by the operation based on the air volume of the air blowing means, and the air volume of the air blowing means for the next week is controlled in time series. On the other hand, if the detected dirt level at the same time of the week increases, the operating air volume for the next week will increase further. Conversely, if the detected dirt level for this week has decreased from the previous week, the operating air volume for the next week will decrease and the prediction accuracy will be improved. Even if there is sudden dirt, it has the effect that it can be leveled and operated.

  In addition, the control unit stores all 365 days of the dirt level value detected every week, and if the dirt level value of the corresponding day of the previous year is high with respect to the operation mode leveled every week, the operation air volume On the contrary, if it is lower than the dirt level value of the previous year, the operation air volume is lowered and the operation can be performed with higher prediction accuracy.

  Further, the control unit is configured to reduce the air volume of the air blowing means that operates intermittently when the continuous time when the air volume of the operating means determined by the dirt level value stored in the previous week becomes zero exceeds a predetermined time. In addition, since no dirt is generated in a time zone in which the stored dirt level is 0, it has an effect of reducing noise by reducing the air volume in intermittent operation in that time zone.

  Further, the control unit is configured to extend the stop time of the intermittent operation when the continuous time when the air volume of the operation means determined by the dirt level value stored in the previous week becomes zero exceeds a predetermined time, In the time zone in which the stored dirt level is 0, no dirt is generated, so that the number of intermittent operations in that time zone is reduced to save energy and suppress the generation of noise.

  The dirt detection means consists of a dust detection part and a gas detection part, and the control part compares the dirt level values detected and stored in each detection part, and detects whether the dirt level value with a large conversion value is due to the dust detection part. The operation pattern of the air blower is changed, and if dust dirt such as pollen is detected, it is operated for a short time with a large air flow, and if bad odor gas such as ammonia is detected It has the effect of operating for a long time with the air volume.

  In addition, the control unit assumes air pollution that occurs due to seasonal factors, based on the data stored for one year, and changes the operation pattern of the air blowing means. It assumes air pollution with high seasonal factors such as pollen. Thus, it has an effect of operating in advance with a large air volume.

  In addition, the control unit is operated so as not to update the stored data on the day when air pollution deviating from the normal life rhythm is detected based on the stored data every 7 days. For air dirt that is not a normal life rhythm such as the above, the dirt level value is not updated, and the operation pattern is not affected by the driving pattern in the normal life rhythm.

In addition, the control unit is provided with an operation switch that can temporarily stop the air volume that is calculated based on the data every 7 days and is determined in time series. If the pattern changes temporarily, the operation determined in chronological order is stopped by operating the operation switch in advance, and the operation is performed in the normal operation in which the operation is performed if air contamination is detected. Have.

  In addition, the control unit is provided with an operation switch that can determine that the air contamination level value detected by the contamination detection means is invalid, and the operation switch is used when releasing a good odor component such as a fragrance into the room. By operating the, the dirt detecting means does not detect and does not perform the operation and does not remove odors.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 to 3, the air cleaner main body 1 is formed in a substantially box shape, a front panel is provided on the front surface of the main body 1, and an air inlet 2 is formed on a side surface of the main body 1. In the main body 1, a filter 3 for purifying air and a fan motor 4 for passing air through the filter 3 are provided, and a blower outlet 9 is provided on a side surface of the main body 1. When the fan motor 4 is driven, air is sucked from the air inlets 2 a and 2 b, cleaned through the filter 3, and then blown out from the air outlet 9.

  A gas detection unit 5 having a gas sensor 5a is provided at the upper left of the main body 1, and a dust detection unit 6 having an optical dust sensor 6a is provided on the side of the main body 1.

  An operation unit 8 is provided at the upper front of the main body 1, a control unit 7 is accommodated inside the operation unit 8, and a calculation unit 12 is provided in the control unit 7. The main body 1 is provided with a dirt display section 10 at the front left end of the main body 1 which represents the dirt state of room air by color change.

  In the above configuration, when the power supply is energized, the control unit 7 converts the output signal detected by the gas detection unit 5 or the dust detection unit 6 into a dirt level value of 0 to 5 at intervals of 20 minutes, and the dirt level for each 20 minutes. The maximum value starts to be stored, and 504 data for a total of 7 days is stored in time series.

  First, when the operation unit 8 is set to automatic operation in order to start the first operation, the fan motor 4 is operated for 10 minutes as a basic operation, and a cycle of stopping for 50 minutes is repeated. When air contamination is detected by the gas detection unit 5 or the dust detection unit 6, the contamination display unit 10 changes from blue to red and starts operation with an air volume corresponding to the contamination level. At this time, the air flow rate of the fan motor 4 with respect to the dirt level detected by the gas detection unit 5 or the dust detection unit 6 has the relationship shown in FIG.

  When the air dirt is cleaned and the dirt level becomes 0, the fan motor 4 stops, but when it is determined that the 50-minute stop state continues, the control unit 7 operates for 10 minutes and the 50-minute stop cycle. Shift to intermittent operation repeatedly.

  During the operation as described above, the control unit 7 converts the signal detected by the gas detection unit 5 or the dust detection unit 6 into six levels of dirt levels 0 to 5, and this dirt level value is set at intervals of 20 minutes. Store as time series data. In addition, although the individual dirt level value at this time stores the maximum value for each 20 minutes, it may be an average value for each 20 minutes.

  In the next week (168 hours after the start of storing the dirt data value), the basic intermittent operation of 10 minutes ON and 10 minutes OFF is performed with the air volume corresponding to the stored dirt level value. For example, as shown in FIGS. 4A and 4B, the dirt level value detected every 20 minutes from 10 o'clock to 11 o'clock is 2, 2 and 1, and the basic intermittent operation for the next week is set to 0 for medium operating airflow. , Medium, 0, weak, 0 intermittent operation at 10 minute intervals. Even when this basic intermittent operation is performed, the indoor air pollution is detected by the gas detection unit 5 and the dust detection unit 6, and the air volume according to the detected dirt level value is added to the air volume 0 section of the basic intermittent operation. Thus, the actual operation as shown in FIG. In this embodiment, the detected dirt level values are 2, 1, 0, respectively.

  In this way, the dirt level of the previous week is memorized in time series, basic intermittent operation is set, and by adjusting the air volume according to the dirt level value of the next week, it can be operated with the air flow assuming dirt, It is possible to operate in accordance with the occurrence of air contamination.

  In this embodiment, the dust detection unit and the gas detection unit are used as the air dirt detection means. However, the same effect can be obtained when the dust detection unit alone or the gas detection unit is used. Can do.

  The gas sensor used in this embodiment is a semiconductor sensor that detects a gas component such as an ammonia sensor that detects ammonia, and the dust sensor is an optical sensor that optically detects dust.

(Embodiment 2)
The present embodiment is different from the first embodiment only in the control method, and the same components are given the same reference numerals and detailed description thereof is omitted.

  As shown in FIG. 5, the calculation unit 10 provided in the control unit 7 compares the stain level value stored until the previous time with the stain level value for each same timer number detected today, and if it has increased, +1, If it decreases, it is calculated as −1, and if it does not increase or decrease, it is calculated as ± 0, and is stored as a predicted dirt level value for the next week.

  In the above configuration, the control unit 7 starts to store the maximum value of the dirt level value detected from the gas detection unit 5 or the dust detection unit 6 every 20 minutes every day, and stores a total of 168 hours in time series. For example, if the previously stored stain level value is 1 and the stain level value detected by the same timer number is 2, the computation unit 10 sets the predicted stain level value to 2 next time, and the control unit 7 is stored in the storage unit 7a. If the previously stored stain level value is 3 and the stain level value detected by the same timer number is 1, the computing unit 10 sets the next stain level value to 2 and stores it sequentially.

  In this way, by continuously calculating the dirt level and determining the next operating air volume, even if sudden dirt occurs, the next day is less affected and air dirt that occurs in daily life A stable cleaning operation corresponding to the state of can be performed.

(Embodiment 3)
The present embodiment is different from the first or second embodiment only in the control method, and those having the same configuration are denoted by the same reference numerals and detailed description thereof is omitted.

  As shown in FIG. 6, the control unit 7 stores all the detected dirt level values every 20 minutes for 365 days, and if the previous storage level value and the previous storage level value are compared and increased, +1 If it is decreasing, it is calculated as −1, and if it is not increasing or decreasing, it is calculated as ± 0, and is stored as a predicted dirt level value of today.

  In the above configuration, for example, as shown in FIGS. 5A and 5B, the dirt level value detected every 20 minutes from 22:00 to 23:00 is 5, 2, 1, and the basic intermittent operation of the next week is the operating air volume. Is an intermittent operation at 10-minute intervals of strong (10 minutes), 0, medium (10 minutes), 0, weak (10 minutes), and 0. However, as shown in FIG. When the level value is 4, 1, 3, the operation air volume is set to intermittent operation of medium (20 minutes), 0, weak (15 minutes), 0, medium (10 minutes), and 0.

  In this way, not only is it possible to calculate the next operating air volume by continuously calculating the dirt level in this way, but also by calculating the next air volume by further calculating the dirt level of the previous year, air pollution due to seasonal factors It is possible to perform a clean operation that predicts the occurrence of air pollution and the occurrence of air pollution due to seasonal events.

(Embodiment 4)
The present embodiment is different from the first or second embodiment only in the control method, and the same components are denoted by the same reference numerals and detailed description thereof is omitted.

  As shown in FIGS. 7 (a) and 7 (b), when there is no absence, the gas detection unit 5 and the dust detection unit 6 are in a time zone in which no air contamination is detected. , 50 minutes OFF), the operation is continued, but if the dirt level value in that time zone becomes 0 continuously for 2 hours, the controller 7 stops without changing the operation time of the intermittent operation 10 minutes. Change the operation to extend the time from 50 minutes to 110 minutes.

  Thus, when the time zone without air dirt detection continues, by extending the stop time of the intermittent operation, it is possible to achieve an energy saving operation with reduced useless air blowing operation, and noise can be reduced. .

  Next, when the dirt level value becomes 0 continuously for 4 hours, the control unit 7 decreases the operation air volume in the intermittent operation as shown in FIG.

  As described above, when the time period in which no contamination is detected continues for a long time, the operation air volume in the intermittent operation is decreased, and in this embodiment, the operation noise can be greatly reduced by setting the minimum air volume. Further, as shown in FIG. 6C, by extending the intermittent operation stop time and shortening the air blowing time from 10 minutes to 5 minutes, further energy saving and noise reduction can be achieved.

(Embodiment 5)
The present embodiment is different from the first or second embodiment only in the control method, and the same components are denoted by the same reference numerals and detailed description thereof is omitted.

  As shown in FIGS. 8 (A), (B), and (C), when the detected maximum value of air contamination is detected by the gas detection unit 5, the operation pattern is set to a gas-corresponding pattern different from the standard pattern. That is, the operating air volume is set to an air volume corresponding to the detection level, but the operating time is doubled to purify gas components that are easy to diffuse and difficult to remove over time. In addition, when the detected maximum value of air contamination is determined by the dust detection unit 6, the operation pattern is a gas-corresponding pattern different from the standard pattern. That is, the operating air volume is increased by one level from the detected level, the operating time is shortened to 2/3, and dust is collected and cleaned at once in a large air volume and in a short time.

  Thus, by detecting the detection value of air dirt detected by each sensor and changing the operation mode, the operation corresponding to the dirt component can be performed, and air dirt of different quality can be efficiently cleaned.

(Embodiment 6)
The present embodiment is different from the first or second embodiment only in the control method, and the same components are denoted by the same reference numerals and detailed description thereof is omitted.

    As shown in FIGS. 9 (a) and 9 (b), for example, the dirt level value detected every 20 minutes from 22:00 to 23:00 becomes 5, 2, and 1, and the basic intermittent operation of the next week has a strong operating air volume (10 minutes). ), 0, medium (10 minutes), 0, weak (10 minutes), 0 intermittent operation at 10 minute intervals. As shown in FIG. In the case of 5, since the detection level is not updated for a time zone with a difference of 3 ranks or more, the next week's operating air volume is strong (20 minutes), 0, weak (15 minutes), 0, weak (10 minutes), 0 intermittent Remember to drive.

  In this way, if the detected dirt level value differs from the dirt level value determined in chronological order by 3 ranks or more, it is judged as air dirt different from the normal life pattern and is not reflected in the driving pattern of the next week. Even if there is an extraordinary occurrence of dirt, you can drive without being affected.

(Embodiment 7)
The present embodiment is different from the first or second embodiment only in the control method, and those having the same configuration are denoted by the same reference numerals and detailed description thereof is omitted.

  As shown in FIGS. 10 and 11 (a), (b), and (c), when the operation switch 13 is provided and the life pattern changes or when it is desired to release good odor components such as fragrances detected by the dirt detection unit For example, the time series operation is temporarily stopped by operating the operation switch 13.

  In this way, when it is desired to temporarily stop the stored dirt level operation, it is possible to achieve an energy saving operation by reducing the useless air blowing operation by operating the operation switch.

  This is a method in which indoor air pollution is stored in time series and the operation is controlled in advance, so that it can be applied to the operation control of humidifiers and air conditioners by replacing the detection object with air humidity and temperature.
