Abstract

PURPOSE:To obtain the simple control software by obtaining the limit point in each control pattern from the related equation between the air quantity and the degree of vacuum, for a suction performance controller. CONSTITUTION:As an example, a pressure sensor is used for a detector 21, and the limit point in clogging is represented by the related equation between the degree H of vacuum and the air quantity Q (e.g. H=alphaQ<2>) for an electrical cleaner having three control patterns A, B, and C according to the kind of a cleaned surface, and then the air quantity Q at present is calculated by a calculation processor 22 from the data obtained by the detector 21 and the limit point H at this time can be set. Accordingly, the need of setting the limit point in clogging of a filter for each control pattern is obviated, and control softwares can be made simple.

However, the air volume changes depending on various factors such as the type of surface to be cleaned, the opening area of the suction port, and the amount of dirt. For this reason, control using a single operating mode in the entire air volume range as in the conventional example may not be able to achieve optimal operation in the various operating conditions described above. Therefore, as shown in FIG. 3, it is necessary to change the control pattern depending on the type of surface to be cleaned, the type of suction port, etc. However, when there are a plurality of control patterns, it is necessary to set the limit point of filter clogging for each control pattern.

The goal is to bring it back. Conversely, when the limit point is exceeded, the rotational speed of the electric blower is lowered to a predetermined value to notify the user that the clogging is severe and to save wasted energy. The purpose is to
