Example Embodiment

[0037] (Example 1)

[0038] figure 1 The circuit structure of the electric vacuum cleaner of the first embodiment of the present invention is shown. For the sake of brevity, the same components as those in the above-mentioned existing electric vacuum cleaner are marked with the same symbols here, and detailed descriptions thereof are omitted.

[0039] in figure 1 Among them, 9 is a suction head for sucking dust from the cleaning surface, and the example here is a suction head for the floor. The suction head 9 for the floor is installed on the extension pipe 5 in a freely detachable manner. A rotating brush 10 and a motor 11 for driving the rotating brush 10 are installed inside the suction head 9 for the floor. The electric motor 11 relies on a power cord 13 provided on the suction channel for power supply.

[0040] The main body 1 of the vacuum cleaner is equipped with an electric fan 2 for generating a dust suction airflow and a dust collecting chamber 6 for collecting dust. ...

Example Embodiment

[0101] (Example 2)

[0102] Figure 7 It is a flowchart of the mode conversion determination of the electric vacuum cleaner of the second embodiment of the present invention, Figure 8 It shows a flowchart for determining the strong / weak mode of the vacuum cleaner. In addition, the same components as those of the electric vacuum cleaner of the prior art and the first embodiment described above are denoted by the same reference numerals, and descriptions thereof will be omitted.

[0103] In the actual implementation form this time, the difference from the above-mentioned first embodiment is that the mode conversion determination process set in the microcomputer 20 in advance, as shown in Table 2, the strength mode is the same, and the mode is determined every time The mode 1 of the conversion process is input into V1, and the strong mode and the weak mode are converted in order.

[0118] (Example 3)

[0119] Picture 9 It is an operation explanatory diagram of the suction head for the floor of the electric vacuum cleaner according to the third embodiment of the present invention. In addition, the same components as those of the conventional electric vacuum cleaner and the electric vacuum cleaner of the above-mentioned embodiment are denoted by the same reference numerals, and the description is omitted.

[0120] in Picture 9 Among them, the difference from the above-mentioned first embodiment is that the roller 24 is arranged at the front of the suction head main body 21.

[0121] Next, the operation of the electric vacuum cleaner of this embodiment will be described.

[0122] When the user is cleaning while holding the handle 8 or the extension tube 5, the suction head 9 for the floor moves back and forth on the floor. At this time, if cleaning is performed on a floor with a height difference or a carpet, depending on the type of the carpet, the suction he...

Abstract

The present invention provides an electric duct collector capable of reducing the user's burden when conversing a mode, comprising an electric fan (2); an on-off switch (18a) mounted on a ground suction head (9) used to inhale the dust on the cleaning face, for detecting the contact condition of the suction head and clean-up ground; a control part (14) having a plurality of power supply modes of different powers and controlling the power supply to the electric fan; and a microcomputer (20) for determining a corresponding mode when a combination of signals of the contact and non contact of the ground suction head and the clean-up ground detected by the on-off switch corresponds with a presetting mode of a plurality of modes; according to a combination of modes wanted by users, the microcomputer judges the combination to determine the mode wanted by users by making the ground suction head to contact or leave from the ground, and controls the switch of the electric fan by a power corresponding with the mode provided by the control part.

Description

technical field [0001] The present invention relates to an electric vacuum cleaner for household or business use, and more particularly, to load control therein. Background technique [0002] first pass Figure 10 and Figure 11 A conventional general electric vacuum cleaner will be described. Figure 10 It is a schematic diagram of the structure of an existing electric vacuum cleaner, Figure 11 It is the circuit diagram of the electric vacuum cleaner. [0003] exist Figure 10 Among them, 1 is the main body of the vacuum cleaner, 2 is the electric blower built in the main body 1 of the vacuum cleaner to generate suction, and 3 is a hose, on which is provided an operation part 4 for switching different powers (working modes) of the electric blower 2, 5 is an extension pipe, and 6 is a dust collection chamber installed in the front part of the main body 1 of the vacuum cleaner for storing dust. connect. The hose 3 alone or together with the extension pipe 5 forms an air ...
