Self-cleaning method for a surface cleaning device

Abstract

The application relates to the household cleaning field and discloses a self-cleaning method of a surface cleaning device, which is applied to a surface cleaning device including a floor brush, the front end of the floor brush is sequentially provided with a liquid supply part, a dirt scraping part and a dirt suction port from top to bottom, the front end of the dirt suction port is provided with a roller brush, the dirt scraping part has a first state of abutting against the roller brush and a second state of being separated from the roller brush and being in front of the dirt suction port, and the self-cleaning method comprises the following steps: controlling the dirt scraping part to deflect towards / draw away from the dirt suction port, so that the dirt scraping part is switched between the first state and the second state. Compared with the related art, the self-cleaning method of the surface cleaning device provided by the application has the advantage that in the self-cleaning process of the surface cleaning device, the self-cleaning effect of hair, fine lines and other linear dirt in the surface cleaning device is improved by controlling the deflection of the dirt scraping part.

Claims

1. A self-cleaning method for a surface cleaning device, applied to a surface cleaning device including a floor brush, wherein the front end of the floor brush is provided with a liquid supply component, a scraping component, and a suction port from top to bottom, and the front end of the suction port is provided with a roller brush, characterized in that, The scraping component has a first state of contacting the roller brush and a second state of being separated from the roller brush and positioned in front of the suction port; the self-cleaning method includes: The scraper is controlled to deflect toward / away from the suction port, so that the scraper switches between the first state and the second state.

2. The self-cleaning method of the surface cleaning device according to claim 1, characterized in that, The control of the scraper to deflect toward / away from the suction port includes: During the forward or reverse rotation of the roller brush, the scraping component is controlled to deflect toward the suction port.

3. The self-cleaning method of the surface cleaning device according to claim 1, characterized in that, After the scraping component switches from the second state to the first state, it controls the roller brush to rotate forward.

4. The self-cleaning method of the surface cleaning device according to claim 1, characterized in that, The control of the scraper to deflect toward / away from the suction port includes: When the scraper deflects away from the suction port, the roller brush is controlled to stop rotating until the scraper switches from the second state to the first state; or, when the scraper deflects away from the suction port, the rotation direction of the roller brush is controlled to be the same as the deflection direction of the scraper.

5. The self-cleaning method of the surface cleaning device according to claim 1, characterized in that, It also includes a hair removal step, which includes: The scraping component is in the second state, and the roller brush rotates alternately in both forward and reverse directions at a speed of v1 for a duration of T1. The scraping component is in the second state, and the roller brush reverses at a speed of v2 for a duration of T2. The scraping component is in the first state, and the roller brush rotates forward at a speed of v2 for a duration of T2, where v2>v1 and v2>T1.

6. The self-cleaning method of the surface cleaning device according to claim 5, characterized in that, During the hair removal step, the liquid supply unit stops supplying liquid, while the blower continues to run.

7. The self-cleaning method of the surface cleaning device according to claim 1, characterized in that, It also includes a roller brush self-cleaning step, which includes: The liquid supply component is activated, the scraping component is in the first state, and the roller brush reverses at a speed of v3 to flush the roller brush cavity wall, which is no higher than the highest point of the roller brush, at a speed of 100 r / min. <v3<300r / min。 8. The self-cleaning method of the surface cleaning device according to claim 1, characterized in that, It also includes a pipeline self-cleaning step, which includes: The liquid supply component starts supplying liquid, the scraper is in the second state, the roller brush stops rotating, and the fan switches between several power levels.

9. The self-cleaning method of the surface cleaning device according to any one of claims 1, 2, 3, 4, 7, and 8, characterized in that, return Obtain the moisture content of the roller brush and / or the liquid level in the cleaning tank, and control the liquid supply plate to supply liquid based on the moisture content and / or the liquid level.

10. The self-cleaning method of the surface cleaning device according to claim 1, characterized in that, It also includes a dirt pretreatment step, which includes: The cleaning device switches between the first state and the second state.
