TECHNICAL FIELD OF THE INVENTION
The present invention relates to an air purifier that removes dust or odorous gas in the air, and more specifically, includes both a dust collector and a deodorizer, and includes both a dust collector and a deodorizer alone. The present invention relates to an air purifier that can blow air at the same air volume as in the case.
[0002]
[Prior art]
Conventional air purifiers are equipped with a dust collection device that uses a dust collection filter, and a deodorization device that combines a deodorization electrode and a deodorization filter by corona discharge, and satisfies the specified performance when both devices are installed. Thus, the air flow rate is determined (for example, see Patent Document 1).

[Problems to be solved by the invention]
When using an air purifier, it is possible that only dust collection or deodorization is required, and by using only one of the dust collection device or deodorization device, the other dust collection device or deodorization device can be wasted. Use can be eliminated. However, in the case of the conventional air purifier, the fan speed of the air blower is set so that the air flow becomes the specified air volume when both the dust collector and the deodorizer are installed, and the set value is recognized by the control unit. Let me. However, if one of the dust collector or deodorizer is removed, the pressure loss of the wind pressure decreases, and if the rotation speed of the blower fan is controlled to a constant speed using an inverter motor, the air flow increases. In some cases, the set dust collection or deodorizing performance changes, and the optimum dust collecting or deodorizing ability cannot be exhibited.
