Problems solved by technology

Although the existing surface cleaning device can use the cleaning components to complete the self-cleaning of the cleaning roller, it cannot automatically clean the dirt suction port and the dirt suction channel. After a long time, bacteria will grow and odor will be emitted, which will give customers a bad experience.

Embodiment 1

[0043] The invention provides a surface cleaning machine and a cleaning seat 4, such as figure 1 As shown, the surface cleaning machine includes a fuselage 1 and a cleaning assembly 2 hinged with the fuselage 1. The fuselage 1 is provided with a water tank 11, a dirt bucket 12 and a dirt suction motor 13. The cleaning assembly 2 includes a frame 21, The driving motor 24 arranged on the frame, the cleaning roller 3 arranged at the bottom of the frame 21 and the machine cover 22 covered on the frame 21, the frame 21 is provided with a dirt suction channel connected with the dirt bucket 12 14. The dirt suction port 15 of the dirt suction channel 14 is set toward and close to the cleaning roller 3, and the cover 22 is also provided with a water spray port 23, and the cleaning roller 3 is driven to rotate by a driving motor (not shown in the figure), During automatic cleaning, the surface cleaning machine is placed on the cleaning seat 4, and the cleaning seat is provided with a cl...

Embodiment 2

[0055] The difference between the present embodiment and the first embodiment is that the self-cleaning method further includes a step D—a sewage suction and air-drying stage after cleaning the dirt suction channels.

[0056]In this embodiment, the length of the dirt suction channel of the surface cleaning machine is 15cm, the suction power of the dirt suction motor changes stepwise, and the suction power P1 of the dirt suction motor is between 0.3P and 0.4P Under the effect of the change of the suction power waveform of the sewage suction motor, the rising height of the cleaning liquid in the sewage suction channel changes between 0.5L and 0.7L. Since the length L of the dirt suction channel in this embodiment is 15cm, it cooperates with the suction power of the dirt suction motor to switch between 0.3P and 0.4P, so that the cleaning liquid can effectively enter the dirt suction channel. The suction power is under the action of the stepped waveform, and flows up and down in t...

Embodiment 3

[0065] The difference between this embodiment and Embodiment 1 is that the self-cleaning method also includes step E—a rinsing stage.

[0066] In this embodiment, the length of the dirt suction channel of the surface cleaner is 20cm, the suction power of the dirt suction motor changes sinusoidally, and the suction power P1 of the dirt suction motor varies between 0.35P and 0.45P , under the action of the suction power waveform change of the dirt suction motor, the rising height of the cleaning liquid in the dirt suction channel varies between 0.6L and 0.8L. Since the length L of the sewage suction channel in this embodiment is 20cm, the sewage suction channel is relatively long, and it cooperates with the sewage suction motor whose suction power changes sinusoidally between 0.35P and 0.45P, so that the cleaning liquid can effectively Enter the sewage suction channel and flow up and down in the sewage suction channel. The height of the cleaning liquid rising in the sewage sucti...

Abstract

The invention belongs to the technical field of cleaning equipment, and particularly provides a self-cleaning method of a surface cleaning machine, the surface cleaning machine comprises a cleaning roller driven by a driving motor, a dirt suction device driven by a dirt suction motor and a liquid supply device, and the dirt suction device comprises a dirt suction port, a dirt containing barrel and a dirt suction pipeline connecting the dirt containing barrel and the dirt suction port. The self-cleaning method comprises the following steps: step A, a cleaning roller cleaning stage; step B, a dirt suction stage; c, a stage of cleaning the sewage suction pipeline: the sewage suction motor is started, the suction power of the sewage suction motor is P1, P1 is larger than or equal to 0.3 P and smaller than 0.5 P, the sewage suction device sucks the cleaning liquid into the sewage suction pipeline through the sewage suction opening, the cleaning liquid flows up and down in the sewage suction pipeline to continuously wash the inner wall of the sewage suction pipeline and the sewage suction opening, and the inner wall of the sewage suction pipeline and the sewage suction opening are cleaned. According to the self-cleaning method, after the cleaning roller is automatically cleaned, the dirt suction opening and the dirt suction channel are independently cleaned, the cleaning efficiency is high, and the cleaning effect is good.

Description

technical field [0001] The invention belongs to the technical field of cleaning equipment, and specifically provides a self-cleaning method for a surface cleaning machine. Background technique [0002] With the improvement of people's living standards, a variety of surface cleaning devices have gradually entered people's daily lives, providing great convenience for cleaning the floor of houses. The existing surface cleaning device includes a cleaning roller, a dirt collection box and a scraping deflector arranged on the cleaning assembly. The cleaning roller is in rotational contact with the surface to be cleaned to wipe the surface to be cleaned. The scraping deflector Rotate the cleaning roller to scrape, and the dirt absorbed by the cleaning roller is scraped off and flows into the dirt collection box. In addition, there is a surface cleaning device. The dirt collection box and the water tank are arranged on the body with a handle bar. In this way, a dirt suction motor n...
