It has a path 7. In this ventilation path 7, an air purification unit 9 such as a filter for air purification and an air blowing unit 6 such as a fan for changing the air volume are provided between the inlet 2 and the outlet 3. Further, an air outlet louver 4 that changes the air blowing direction is provided in the vicinity of the air outlet 3.

  Further, a dirt detection means 10 is provided on the front or side of the main body 1 in order to detect the dirt of the indoor air. The dirt detection means 10 is composed of, for example, a light emitting element, a light receiving element, and a lens, and irradiates dust with light emitted from the light emitting element, and light reflected from the dust is received by the light receiving element through the lens to detect dust. A device that counts the number of dusts by outputting a pulse signal each time is used.

  And the control part 8 which controls the operation | movement of the said ventilation part 6 and the blowing louver 4 is provided. The control unit 8 is provided with an operation panel having various switches, and the user operates the operation panel to the control unit 8 with respect to the operation air volume of the blower unit 6, the operation mode and use described later. Instructions such as the size of the room to be performed.

  As shown in FIG. 3, the control unit 8 includes a dirt determination unit 21, an output control unit 31, and a timer unit 51. The user instructs the output control unit 31 about the operation mode (“normal mode” or “sleeping mode”) and the size of the room by operating the operation panel.

  As shown in FIG. 4, the dirt determination means 21 has at least two (six in the present embodiment) dirt levels as outputs. The degree of contamination is related to the number of pulses of the contamination detection means 10 within a unit time. For example, if the number of pulses from the dirt detection means 10 is 7, the dirt determination means 21 determines the dirt degree as 3.

  The timer unit 51 issues a time command to the output control unit according to the degree of contamination of the contamination determining means 21. The output control unit 31 controls the blower unit 6 according to the instructed operation mode, the room size, and the signals from the timer unit 51 and the dirt determination means 21.

The operation of the output control unit 31 will be described in more detail. As shown in FIG. 5, the output control section 31, when specifying the "sleep mode" before the user sleep operated air purifier (S61), specifies the air volume V ₁ to the blower 6 (S62 ). The air volume V ₁ continues for a time T ₁ .

Based on the experiment, an air volume V ₁ table that can sufficiently purify the entire room is set according to the size of the room and the degree of contamination. The output control unit 31 instructs the air blowing unit 6 by referring to the air volume V ₁ table based on the room size input by the user and the degree of dirt in the room by the dirt determining means 21. For example, if the dirt level is 5 in an 18 tatami room, 4.0 m ³ / min is instructed.

An example of the time T ₁ is shown in FIG. Based on the experiment, a time T ₁ table capable of sufficiently purifying the entire room is set in accordance with the size of the room and the degree of contamination. The output control unit 31 that the user to see the room in time T ₁ table from contamination degree in breadth and dirt determination unit 21 of the room entered, to indicate the air volume V ₁ to between blower 6 for a predetermined time. For example, if the dirt level is 5 in an 18 tatami room, 15 minutes is instructed.

This time T ₁ is set to a predetermined time T _MAX at the maximum, and by setting an upper limit, it is possible to prevent the user from continuing to operate with a large air volume V ₁ while sleeping.

Thereafter, after the elapse of time T ₁ (S64), a quiet air volume V ₂ (for example, 29 dB or less) which is not noticed while sleeping is designated to the blower 6 (S65).

At this time, an example of the air volume V ₂ is shown in FIG. Based on the experiment, an air volume V ₂ table that can sufficiently purify the entire room is set according to the size and the degree of contamination of the room. The output control unit refers to the air volume V ₂ table based on the room size input by the user and the degree of soiling in the soil determination means 21, thereby instructing the air blowing unit 6 with a predetermined air volume. For example, if the degree of dirt is 5 in an 18 tatami room, 2.0 m ³ / min is instructed. Since the driving with the air volume V ₂ is sleeping, the maximum air volume value V _MAX is fixed and the driving is performed so as not to exceed the maximum value V _MAX . Thereafter, when the user designates “normal mode”, the output control unit 31 instructs the air blowing unit 6 on the air volume set by the user (S63).

As described above, when the user instructs the sleep mode, the air cleaner according to the present embodiment operates with a large air volume V ₁ according to the degree of dirt in the room and falls asleep during the time period until the user goes to sleep. operating at a small air volume V _2. Each operation in the sleep mode has the following actions and effects.

In the air volume V ₁ operation in the time zone of up to go to bed, even if somewhat noisy during the awake until the user go to bed, quickly remove the house dust and dust of the room in the air volume of the stronger, to clean the room.

In FIG. 5, it has been described that when the time T _{1 has} elapsed, the air volume V ₂ is determined according to the degree of dirt in the room, and then the operation is performed with the air volume as it is. In contrast, within the S65, check the interior of the dust concentration at predetermined time intervals, may be re-set air volume V ₂ corresponding to the dust concentration in the chamber.
