Surface cleaning device

Abstract

The invention relates to a surface cleaning device, which comprises a device main body, wherein a cleaning liquid tank, a liquid applying unit, a dirty liquid suction unit, a heating unit and a control unit, wherein the dirty liquid suction unit comprises a suction nozzle, a suction motor and a dirty liquid tank; the heating unit comprises a first electric heating body which extends into a liquid storage chamber at least partially; the surface cleaning device is such configured that the surface cleaning device at least comprises a pre-heating mode and a cleaning mode; when the surface cleaning device is under the pre-heating mode, the first electric heating body is under a heating state and the suction motor is under a turned-off state; while when the surface cleaning device is under a cleaning mode, the first electric heating body is under a turned-off state and the suction motor is under a turned-on state; the control unit comprises a mode selecting switch; and the mode selecting switch is such configured that a user operates the surface cleaning device which works in accordance with either the pre-heating mode or the cleaning mode. According to the scheme, the surface cleaning device, which implements cleaning by virtue of heated cleaning liquid, is good in cleaning effect, environment-friendly and pollution-free.

Description

technical field [0001] The invention relates to a surface cleaning device. Background technique [0002] Carpet cleaning apparatus known in the art operate by spraying a cleaning solution onto the carpeted surface and, in continuous operation, sucking the cleaning solution out substantially simultaneously with the soil on the carpet. As disclosed in the publication number CN1387818, the "device for cleaning a surface" is used to sprinkle cleaning liquid onto the surface and suck it out substantially simultaneously with the dirt on the surface in continuous operation; figure 1 As shown, the upright carpet cleaning machine includes a pivot handle portion 12 for urging a floor engaging portion (or foot) 14 on a carpeted floor. The floor engaging section 14 includes a brush assembly 34 with a plurality of rotating scrub brushes 16 for scrubbing floors. A sump assembly 18 is mounted to the floor engaging portion 14 of the washing machine. The sump 18 includes a clean water sum...

Problems solved by technology

But because the heat energy of the hot air flowing out from the suction motor and the heat generated by the suction motor itself are too small, the heat energy that can be used to heat the cleaning liquid is even less, so in this solution, it will eventually flow onto the surface to be cleaned. Compared with the unheated cleaning solution, the temperature of the cleaning solution does not change much. Even if the cleaning solution is heated, its cleaning ability is limited; and in this scheme, due to the heat transfer, the layout of the air pipeline and the solution pipeline is responsible. Increased production costs
