Abstract

An eco-friendly cleaning device and a control method thereof are provided, which can reduce detergent usage and water usage by maximizing cavitation. The control method is a method for controlling a cleaning device comprising a cleaning step in which a first mode and a second mode are performed sequentially. The first mode includes supplying cleaning water to a cleaning chamber at a first water level, drawing cleaning water from the cleaning chamber into an internal flow path of a cleaning blade, and spraying cleaning water upward through an upper surface spray hole of the blade. The second mode includes supplying cleaning water to the cleaning chamber at a second water level higher than the first water level, drawing cleaning water from the cleaning chamber into an internal flow path of the blade, spraying cleaning water upward through the spray hole of the blade, and generating ultrasonic waves using a vibrator.

Description

Dishwasher with Reduced Detergent and Water Usage and Method of Controlling Thereof The present invention relates to a dishwasher. More specifically, it relates to an eco-friendly washing device and a control method thereof that can reduce detergent usage and water usage by maximizing cavitation. A dishwasher is a general term for a washing device that automatically washes and dries tableware such as bowls and plates. Traditionally, it was common practice to place dishwashers on a surface, such as a table near the sink. However, this conventional method required a significant amount of installation space, posing a problem that made it difficult to utilize kitchen space efficiently. In particular, since the space occupied by a dishwasher increases as its capacity grows, this issue acted as a limiting factor in increasing the capacity of dishwashers. FIG. 1 is a perspective view showing a washing system including a sink equipped with a washing device according to one embodiment of the present invention. FIG. 2 is a perspective view showing the chamber door of the cleaning device of FIG. 1 in an open state. FIG. 3 is an exploded perspective view of the sink, washing device, and tray of the washing system of FIG. 1. Figure 4 is a perspective view showing the interior of the cleaning chamber of the cleaning device of Figure 3. Figure 5 is a plan view showing the bottom portion of the cleaning chamber of the cleaning device of Figure 3. Fig. 6 is an exploded perspective view of the cleaning device of Fig. 3 partially disassembled. Figure 7 is a cross-sectional schematic diagram illustrating the flow path of the cleaning system of Figure 1. FIG. 8 is a flowchart illustrating a control method for a cleaning device according to an embodiment of the present invention. FIG. 9 is a flowchart showing the first mode washing step of FIG. 8 in detail. FIG. 10 is a flowchart showing the second mode washing step of FIG. 8 in detail. FIGS. 11 to 13 are drawings for explaining the first mode cleaning step of FIG. 9. FIGS. 14 to 17 are drawings for explaining the second mode cleaning step of FIG. 10. The advantages and features of the present invention and the methods for achieving them will become clear by referring to the embodiments described below in detail together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below but may be implemented in various different forms. The embodiments are provided merely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims. That is, various modifications may be made to the embodiments presented by the present invention. The embodiments described below are not intended to limit the forms of implementation and should be understood to include all modifications, equivalents, and substitutions thereof. Unless otherwise defined, all terms used in this specification (including technical and scientific terms) may be used in a meaning that is commonly understood by those skilled in the art to which the present invention pertains. Additionally, terms defined in commonly used dictionaries are not to be interpreted ideally or excessively unless explicitly and specifically defined otherwise. Spatially relative terms such as 'above,' 'upper,' 'on,' 'below,' 'beneath,' and 'lower' may be used to facilitate the description of the relationship between one element or component and another, as illustrated in the drawings. When used in addition to the directions depicted in the drawings, spatially relative terms should be understood as encompassing different orientations of the elements. For example, if an element depicted in the drawing is flipped, an element described as being 'below' or 'beneath' another element may be placed 'above' of that other element. Therefore, the exemplary term 'below' may encompass both the downward and upward directions. In this specification, "and/or" includes each of the mentioned items and all combinations of one or more. Also, the singular form includes the plural form unless specifically stated otherwise in the text. As used in this specification, "comprises" and/or "comprising" do not exclude the presence or addition of one or more other components in addition to the mentioned components. A numerical range indicated by "to" indicates a numerical range that includes the values listed before and after it as a lower and upper limit, respectively. "Approximately" or "about" means a value or numerical range within 20% of the value or numerical range listed after it. In this specification, ordinal modifiers such as 'first component,' 'second component,' and 'first-1 component' are used merely to distinguish one component from another when referring to components. Accordingly, the first component referred to below may be referred to as the second component within the
