    Abstract: FIG. 1 is a front view of the first image in a sequence of a first embodiment of a display screen or portion thereof with transitional graphical user interface, showing our new design;
    FIG. 2 is a front view of the second image thereof;
    FIG. 3 is a front view of the third image thereof;
    FIG. 4 is a front view of the fourth image thereof;
    FIG. 5 is a front view of the fifth image thereof;
    FIG. 6 is a front view of the sixth image thereof;
    FIG. 7 is a front view of the seventh image thereof;
    FIG. 8 is a front view of the eighth image thereof;
    FIG. 9 is a front view of the first image in a sequence of a second embodiment of a display screen or portion thereof with transitional graphical user interface, showing our new design;
    FIG. 10 is a front view of the second image thereof;
    FIG. 11 is a front view of the third image thereof;
    FIG. 12 is a front view of the fourth image thereof;
    FIG. 13 is a front view of the fifth image thereof;
    FIG. 14 is a front view of the sixth image thereof;
    FIG. 15 is a front view of the seventh image thereof; and,
    FIG. 16 is a front view of the eighth image thereof.
    The appearance of the transitional image sequentially transitions between the images shown in FIGS. 1 to 8, and between the images shown in FIGS. 9 to 16, respectively. The process or period in which one image transitions to another forms no part of the claimed design.
    The outer perimeters illustrated by broken lines in FIGS. 1-16 depict a display screen or portion thereof and forms no part of the claimed design. The remaining broken lines depict portions of the graphical user interface that form no part of the claimed design.

    Abstract: An electrical appliance having an electrostatic dust collecting device includes a main body including an inlet; a charging device disposed on the main body at an edge of the inlet and configured to charge contaminants in air; an air moving device disposed inside the main body and configured to suck air containing contaminants and exhaust the air to an outside; and a dust collecting device disposed in an air passage and configured to collect contaminants charged by the charging device from the air. The charging device includes a plurality of carbon fiber electrodes disposed toward the inlet and configured to generate electrons to charge contaminants; a printed circuit board on which the plurality of carbon fiber electrodes are disposed; and a ground electrode disposed adjacent to the printed circuit board without facing the plurality of carbon fiber electrodes.
