Description

Surface cleaning apparatus and surface cleaning system

Technical Field

The present disclosure relates to cleaning device/cleaning system technology, and more particularly to a surface cleaning device and a surface cleaning system.

Background

One development route in the scrubber industry is the use of steam as a cleaning agent.

Steam washers typically require a boiler as the steam generator. After the cleaning liquid is heated by the boiler, the vapor is pumped to a flat plate applicator where it contacts the surface being cleaned.

An advantage of the steam system is that the temperature generated can be effective in killing various microorganisms, bacteria, microorganisms and mites. However, boiler systems suffer from high power and inefficient heating, and the high power requirements for steam generation do not allow sufficient surplus power to run the vacuum motor to recover the contaminated water from the cleaned surface, so cleaning performance is further hampered.

FIG. 10 is a schematic view of a partial configuration of a surface cleaning apparatus according to one embodiment of the present disclosure, and referring to FIG. 10, a surface cleaning apparatus 1000 according to a preferred embodiment of the present disclosure, the first control element includes a flow diversion assembly 215 connected to at least a first liquid reservoir 201, a first outlet portion 2112 of the flow diversion assembly 215 is connected to a thick film heater 213, a second outlet portion 2122 of the flow diversion assembly 215 is connected to a liquid distributor 1041 disposed on the cleaning section 104, and the first outlet portion 2112 and the second outlet portion 2122 of the flow diversion assembly 215 are adapted to be selectively controlled such that cleaning liquid flows from the first liquid reservoir 201 to at least one of the thick film heater 213 and the liquid distributor 1041.

By means of the second trigger described above, the flow rate of the liquid delivered by the shunt assembly 215 to the thick film heater 213 can be controlled to control the vapor output flow rate of the thick film heater 213, for example, the flow rate can be controlled by operating the second trigger to operate the degree of opening and closing of a flow control element (valve, etc.) between the shunt assembly 215 and the thick film heater 213.

Two flow control elements may be provided in the flow divider assembly 215, one for controlling the flow of liquid delivered by the flow divider assembly 215 to the thick film heater 213 and the other for controlling the flow of liquid delivered by the flow divider assembly 215 to the liquid distributor 1041, and the flow divider assembly 215 may include a three-way structure adapted to configure the two flow control elements.

Based on the flow diversion assembly 215, the cleaning liquid in the first liquid reservoir 201 of the present disclosure can be selectively sent to the thick film heater 213 and/or the liquid dispenser 1041, depending on whether the wash function control and/or the steam function control on the handle portion 300 are activated.

The floor washing function control key may be one of the control keys 301 on the handle portion 300, or may be a floor washing function control key displayed on the touch panel or touch screen 209 described above.

With the surface cleaning apparatus 1000 of the various embodiments described above, in any event, vacuuming can be performed by turning on the vacuum suction source 2032 to create suction at the vacuum inlet portion 2031 to remove dry or wet debris from the surface being cleaned without the application of steam or cleaning liquid.

When the cleaning liquid is required to clean the surface, the floor-washing function control key is operated, the cleaning liquid in the first liquid storage 201 enters the liquid supply pipe 210 and flows out to the surface of the cleaning part 104, such as a rotary brush, via the outlet of the liquid distributor 1041, and the rolling rotary brush removes the debris/dirt on the floor along with the cleaning liquid.

When it is required to apply heated steam onto a surface to be cleaned, the steam function control key is operated. Thus, heated steam may be selectively applied to the surface to be cleaned to heat the surface to be cleaned. This function provides the user with the option of alternating between heated vapor and liquid. When the steam function control key is operated, e.g., pressed, the cleaning liquid flows through the liquid supply line 210 and into the thick film heater 213, and the cleaning liquid is rapidly heated to heated steam, dispensed from the steam dispensing ports 1031 (referring to fig. 17, 6 steam dispensing ports 1031 are exemplarily shown), and released onto the surface being cleaned. After the surface being cleaned has been treated with steam, tenacious surface adhesion debris is softened and removed to be drawn into the vacuum suction opening 110 by the rolling rotating brush (see fig. 17), and any liquid generated on the surface by the heated steam or cleaning liquid collects into the vacuum suction opening 110 and eventually into the second liquid reservoir 202. Preferably, a first wiper strip (upper wiper strip) and a second wiper strip (lower wiper strip) may be disposed at both sides of the vacuum suction port 110.

According to a preferred embodiment of the present disclosure, the heating steam may be continuously delivered to apply to the surface to preheat the surface, which in turn heats any cleaning liquid that may be subsequently applied to the surface to bring the temperature of the cleaning liquid above that of the surface to be treated or other surface to be cleaned, and further, the heated surface to be treated will reduce any heat loss from the heated cleaning liquid applied to the surface to be treated due to the elevated temperature of the cleaning liquid applied to the surface to be treated.

According to a preferred embodiment of the present disclosure, the cleaning part 104, e.g., the rotary brush, may be driven by a driving motor separate from the vacuum suction source 2032, and may be individually controlled so that the cleaning part 104, the vacuum suction source 2032 may be operated independently of the thick film heater 213. In addition, the vacuum motor of the vacuum suction source 2032 and the drive motor of the rotating brush may be turned off, so that the surface cleaning apparatus 1000 of the present disclosure can apply only heated steam, removing the working air flow generated by the vacuum motor and the additional air circulation generated by the rotating brush results in higher surface temperatures, thereby enhancing the cleaning effect.

Fig. 7 is a schematic partial structural view of a main body portion 200 of a surface cleaning apparatus according to one embodiment of the present disclosure.
