Description

Surface cleaning apparatus and surface cleaning system

Technical Field

The present disclosure relates to the field of cleaning devices/cleaning systems, and more particularly, to a surface cleaning device and a surface cleaning system.

Background

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

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

The advantage of the steam system is that the resulting temperature is effective in killing various microorganisms, bacteria, microorganisms and mites. However, the boiler system has problems of high power and low heating efficiency, and the high power requirement for generating steam does not allow enough surplus power to operate the vacuum motor to recover the dirty water of the cleaning surface, so cleaning performance is further hindered.

Detailed Description

The present disclosure is described in further detail below with reference to the drawings and the embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant content and not limiting of the present disclosure. It should be further noted that, for convenience of description, only a portion relevant to the present disclosure is shown in the drawings.

In addition, embodiments of the present disclosure and features of the embodiments may be combined with each other without conflict. The technical aspects of the present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Unless otherwise indicated, the exemplary implementations/embodiments shown are to be understood as providing exemplary features of various details of some ways in which the technical concepts of the present disclosure may be practiced. Thus, unless otherwise indicated, features of the various implementations/embodiments may be additionally combined, separated, interchanged, and/or rearranged without departing from the technical concepts of the present disclosure.

The use of cross-hatching and/or shading in the drawings is typically used to clarify the boundaries between adjacent components. As such, the presence or absence of cross-hatching or shading does not convey or represent any preference or requirement for a particular material, material property, dimension, proportion, commonality between illustrated components, and/or any other characteristic, attribute, property, etc. of a component, unless indicated. In addition, in the drawings, the size and relative sizes of elements may be exaggerated for clarity and/or descriptive purposes. While the exemplary embodiments may be variously implemented, the specific process sequences may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in reverse order from that described. Moreover, like reference numerals designate like parts.

When an element is referred to as being "on" or "over", "connected to" or "coupled to" another element, it can be directly on, connected or coupled to the other element or intervening elements may be present. However, when an element is referred to as being "directly on," "directly connected to," or "directly coupled to" another element, there are no intervening elements present. For this reason, the term "connected" may refer to physical connections, electrical connections, and the like, with or without intermediate components.

For descriptive purposes, the present disclosure may use spatially relative terms such as "under … …," under … …, "" under … …, "" lower, "" above … …, "" upper, "" above … …, "" higher "and" side (e.g., in "sidewall") to describe one component's relationship to another (other) component as illustrated in the figures. In addition to the orientations depicted in the drawings, the spatially relative terms are intended to encompass different orientations of the device in use, operation, and/or manufacture. For example, if the device in the figures is turned over, elements described as "under" or "beneath" other elements or features would then be oriented "over" the other elements or features. Thus, the exemplary term "below" … … can encompass both an orientation of "above" and "below". Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. Furthermore, when the terms "comprises" and/or "comprising," and variations thereof, are used in the present specification, the presence of stated features, integers, steps, operations, elements, components, and/or groups thereof is described, but the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof is not precluded. It is also noted that, as used herein, the terms "substantially," "about," and other similar terms are used as approximation terms and not as degree terms, and as such, are used to explain the inherent deviations of measured, calculated, and/or provided values that would be recognized by one of ordinary skill in the art.

With the surface cleaning apparatus 1000 of the various embodiments described above, in any event, suction 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 to be cleaned without the application of steam or cleaning liquid.

When it is necessary to clean the surface with the cleaning liquid, the floor cleaning function control key is operated, the cleaning liquid in the first liquid reservoir 201 enters the liquid supply line 210, flows out onto the surface of the cleaning portion 104 such as a rotating brush via the outlet of the liquid dispenser 1041, and the rolling rotating brush dissolves and removes debris, dirt, and the like on the floor with the cleaning liquid.

When it is desired to apply heated steam to the surface to be cleaned, the steam function control key is operated. Thus, the 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 vapor function control is operated, e.g., squeezed, cleaning liquid flows through the liquid supply line 210 and into the thick film heater 213, the cleaning liquid is rapidly heated to heated vapor, dispensed from the vapor dispensing ports 1031 (referring to fig. 17, which illustrates 6 vapor dispensing ports 1031, for example), and released onto the surface being cleaned. After the surface being cleaned is steamed, the tough surface sticking debris is softened and falls off, thereby being caught at the vacuum suction port 110 by the rolling rotating brush (refer to fig. 17), and any liquid generated on the surface by the heated steam or cleaning liquid is collected into the vacuum suction port 110, and finally collected into the second liquid reservoir 202. Preferably, a first wiper (upper wiper) and a second wiper (lower hanger) may be provided at both sides of the vacuum suction port 110.

According to a preferred embodiment of the present disclosure, the heating steam may be continuously applied to the surface to preheat the surface, which in turn heats any cleaning liquid that may be applied to the surface later, such that the temperature of the cleaning liquid is higher than the surface to be treated or other surface to be cleaned, and further, the heated surface to be treated will reduce any heat loss of the heated cleaning liquid applied to the surface to be treated due to the increased temperature of the cleaning liquid applied to the surface to be treated.

According to a preferred embodiment of the present disclosure, the cleaning portion 104, e.g., a rotating brush, may be driven by a drive motor separate from the vacuum suction source 2032 and may be controlled separately so that the cleaning portion 104, the vacuum suction source 2032, may operate independently of the thick film heater 213.
