  Further, as shown in FIG. 2 (b), the tatami mat setting unit 7 can switch the setting to three levels of less than 10 tatami mats, 10 tatami mats or more and less than 15 tatami mats, and 15 tatami mats or more. The user operates the tatami mat setting unit 7 according to the size of the room to be installed, and for example, when the setting is 15 tatami mats or more, the rotational speed of each air volume is weak notch 550 rpm, medium notch 750 rpm, When it is determined to be strong 950 rpm and set to 10 tatami or more and less than 15 tatami, the rotation speed of each airflow is determined to be weak notch 500 rpm, medium notch 700 rpm, strong 900 rpm, and when it is set to less than 10 tatami The rotation speed of each air volume is determined to be weak notch 450 rpm, medium notch 650 rpm, and strong 850 rpm, and is changed to the set rotation speed of each air volume by the control unit 8, and the gas detection unit of the dirt detection means And the contamination level by the dust detection unit 6, driving the fan motor 4, to purify the room air.

(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.

  First, when the power source is energized, the control unit 8 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 maximum dirt level value for each 20 minutes. A value is started to be stored, and 72 pieces of data for a total of 24 hours are stored in a time series as a specified time.

  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 11 changes from blue to red and starts operation with an air volume corresponding to the contamination level.

  When the air dirt is cleaned and the dirt level becomes 0, the fan motor 4 stops. When it is determined that the 50-minute stop state continues, the controller 8 operates for 10 minutes and the 50-minute stop cycle. Shift to intermittent operation repeatedly.

  During the operation as described above, the control unit 8 converts the signal detected by the gas detection unit 5 or the dust detection unit 6 into a 6-level contamination level value of 0 to 5, and this contamination level value is set at intervals of 20 minutes. Store as time series data for the predicted operation of the next day. 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.

  On the next day (24 hours after the start of storage of the dirt data value), the air volume based on the rotational speed obtained by adding the determination based on the setting signal from the tatami mat setting unit 6 to the air volume corresponding to the stored dirt level value. Basic intermittent operation of 10 minutes ON and 10 minutes OFF is performed.

  For example, as shown in FIGS. 4 (a), (b), and (c), the contamination level values detected every 20 minutes from 22:00 to 23:00 are 3, 2, and 1, and the basic intermittent operation of the next day is performed. The operation air volume is intermittent operation at intervals of 10 minutes of medium 700 rpm (10 minutes), 0, medium 700 rpm (10 minutes), 0, weak 500 rpm (10 minutes), 0, but 10 tatami or less by the tatami mat setting unit 7 Is set to intermittent operation at intervals of 10 minutes: middle 650 rpm (10 minutes), 0, middle 650 rpm (10 minutes), 0, weak 450 rpm (10 minutes), 0, and the tatami number setting unit 7 sets 15 If it is set as tatami mat or higher, it is set to intermittent operation at intervals of 10 minutes: middle 750 rpm (10 minutes), 0, middle 750 rpm (10 minutes), 0, weak 550 rpm (10 minutes), 0, Even when performing basic intermittent operation, The performs detection by the gas detector 5 and the dust detection unit 6, the air volume in accordance with the detected dirt level value, performing production operation was added to the airflow 0 interval of the basic intermittent operation.

  As described above, when the indoor space is wide due to the number of tatami mats set by the tatami mat number setting unit 7, it is assumed that the actual dirt amount is larger than the detected dirt amount, and the operating air volume is increased. To increase the cleaning effect, and if the indoor space is small, it is assumed that the actual amount of dirt is less than the detected amount of dirt, and the rotational speed is reduced to reduce the operating air volume and reduce noise. Can be cleaned.

  In addition, although the number of rotations of each air volume is changed according to the number of tatami mats set here, there is a difference in effect even if the operation notch is raised by one step when the room is large, or the operation notch is lowered by one step when the room is small. There is no difference in operation and effect even if the operation time is extended from 10 minutes to 15 minutes when the room is large, or when the operation time is reduced from 10 minutes to 5 minutes when the room is small.

(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 FIGS. 5A, 5B, and 5C, when the dirt level 5 continues twice or more in the same time zone, the number of tatami mats set by the tatami mat setting section 7 is increased by one step. On the contrary, when the dirt level 1 continues twice or more, the tatami number set by the tatami mat setting unit 7 is decreased by one step and the tatami number is operated at the rotation speed. .

In this way, in a time zone when there is a lot of air pollution, the rotation speed is increased to increase the dirt removal speed, and conversely, the rotation speed is reduced during a time period when there is little air pollution to efficiently remove air pollution with low noise. Can be removed.

The number of tatami mats is increased by one step from the number of revolutions, and the specified operation time is reduced from 10 minutes to 5 minutes. When the stored dirt level value is a signal from the gas detection unit 5, the next day's air volume is operated at the number of tatami mats that is one step lower than the tatami mat number of revolutions set by the tatami mat number setting unit 7. In addition, the specified operating time is extended from 10 minutes to 15 minutes.

  In this way, if the detected dirt substance is dust, the operating air volume is increased and removed in a short time, and if it is a gas component such as odor, it is efficiently removed by reducing the operating air volume and extending the operating time. be able to.

  By setting the size of the room to be used, it is possible to efficiently operate with the optimum air volume, so that it can be applied to the operation control of an air conditioner capable of automatic operation.
