Description

Technical Field

[0001] This utility model relates to the field of washing equipment technology, specifically a cleaning device that significantly reduces ion residues on the surface of utensils through steam condensation and replacement, and is especially suitable for cleaning scenarios with strict requirements for water stain control, such as baby bottle washing machines and dishwashers. Background Technology

[0002] After washing, rinsing, and drying, cleaning equipment (such as dishwashers and bottle washers) often leaves white or hazy water stains on the surface of containers. The root cause of this problem is the crystallization of dissolved hardness ions such as calcium and magnesium during the evaporation process of residual trace amounts of water. Existing solutions mainly focus on front-end water treatment or chemical assistance, both of which have significant limitations. 1. Water softener / deionization filter solution: This method removes ions from the water source through ion exchange. While effective, it requires users to regenerate or replace the filter cartridge regularly, increasing operating costs, maintenance burden, and equipment space requirements.

[0003] 2. Brightening agent (rinsing agent) solution: This method reduces the surface tension of water by adding chemical agents, allowing the water film to flow away quickly and reducing residue. However, this method introduces additional chemical consumables, is not environmentally friendly, and only reduces the amount of residual water, failing to eliminate ions already present in the water.

[0004] Traditional steam-assisted solutions: Some equipment uses steam for sterilization or auxiliary drying. However, this solution is not very effective in solving water stain problems, mainly because: it is usually used after high-temperature rinsing, the temperature of the utensils is too high, and the amount of steam condensed is insufficient; moreover, ordinary steam carries a large number of tiny droplets rich in ions, which may actually aggravate ion deposition in local areas of the utensils after condensation.

[0005] Therefore, there is a need for a cleaning device that can effectively reduce the final ion residue through physical processes without relying on consumables or chemicals. Utility Model Content

[0006] To address the problems of existing technologies in removing water stains being ineffective, requiring complex user maintenance, or introducing chemical additives, this invention provides a low-water-stain cleaning device. This device aims to actively reduce the ion concentration of residual liquid on the surface of containers through physical displacement at the end of the cleaning process, creating low-water-stain conditions for subsequent drying.

[0007] To solve the above-mentioned technical problems, this utility model provides a low-water stain cleaning device, including a machine body, a washing chamber disposed in the machine body, a water supply system for supplying water to the washing chamber, and a control system for controlling the operation of the whole machine, and further including: a steam generator, the steam output end of which is connected to the washing chamber; The control system is configured to perform the following operations: The water supply system is controlled to supply rinse water that is not actively heated during the final rinsing stage; After the rinsing process is completed, the steam generator is controlled to introduce hot steam into the washing chamber.

[0008] To further optimize this technical solution, a steam-water separator is installed on the steam output path of the steam generator.

[0009] To further optimize this technical solution, the steam-water separation device includes a separator for physical separation of steam and / or a heating unit for superheating steam.

[0010] To further optimize this technical solution, the separator used for physical separation is a cyclone separator or a baffle plate separator.

[0011] Further optimization of this technical solution includes a ventilation device installed in the washing chamber, and the control system is further configured to control the activation of the ventilation device during the final rinsing stage.

[0012] Further optimization of this technical solution includes a vibration mechanism for causing the dishes in the washing chamber to vibrate. The control system is also configured to control the vibration mechanism to operate after the rinsing process is completed, before steam is introduced, or at the beginning of steam introduction.

[0013] To further optimize this technical solution, the cleaning equipment mentioned is a baby bottle cleaner or a dishwasher.

[0014] The beneficial effects of this utility model are: Reduce water stains at the source: Through the core physical process of "rinsing and cooling - steam condensation and replacement", the high-ion concentration liquid remaining on the surface of the vessel is actively replaced with low-ion concentration liquid before the drying process begins, reducing the risk of water stains forming during the subsequent drying process.

[0015] User-friendly and environmentally friendly: No user-managed soft water salts or chemical rinsing agents are required, reducing long-term operating costs and environmental burden.

[0016] Stable and reliable results: By controlling the rinsing water temperature, using optional steam drying and ventilation cooling, the effectiveness and consistency of the condensation replacement process are ensured. Attached Figure Description

[0019] like Figure 1 As shown, the cleaning equipment of this utility model is described using a dishwasher as an example. The equipment includes a control system, washing chambers 1-3, a water supply system 2, a water heater 3, a water pump 4, spray arms 1-2, an electric steam generator 5, a steam-water separator 6, a steam pipeline 7, a drying heater 8, a ventilation device 9, and a vibration mechanism 10.

[0020] Its core working process is as follows: Rinsing and Cooling: After the main wash cycle, during at least the final rinse cycle, the control system does not heat the rinse water. Instead, room temperature water is directly introduced through the spray arms 1-2 for rinsing. Simultaneously, the control system activates the ventilation device 9 (such as a fan) to accelerate airflow within the washing chambers 1-3 and expel water vapor. This process utilizes room temperature water rinsing and ventilation to enhance evaporation, effectively lowering the temperature of the dishes and the washing chambers 1-3.

[0021] The phrase "at least" for the final rinse cycle here refers to either the final rinse cycle or the last few rinse cycles. Since the main wash cycle is hot water, the chambers 1-3 and the dishes are heated by hot water after washing. Therefore, rinsing with unheated water only in the final rinse cycle is insufficient to achieve a lower temperature. Thus, unheated water can be used in the pre-rinse cycle before the final rinse cycle to minimize the temperature of the chambers 1-3 and the dishes being washed.

[0022] Forced ventilation during rinsing serves two purposes: firstly, the splashing water in washing chambers 1-3 during rinsing creates a large evaporation surface area, resulting in greater evaporative cooling power; secondly, ventilation during rinsing ensures that the vessel surface remains in dynamic contact with water, preventing ion precipitation. Ventilation before or after rinsing, however, can lead to ion precipitation.

[0023] Shaking assistance: After the rinsing process is completed, the control system can control the shaking mechanism 10 to make the bowl or dish vibrate slightly, causing the water droplets to merge and fall off.

[0024] Steam condensation and replacement: After rinsing and draining, the control system starts the electric steam generator 5. The generated high-temperature steam first passes through the steam-water separator 6 (such as a cyclone separator) to reduce the amount of water droplets it carries, and is introduced into the washing chambers 1-3 through the steam pipes 7 as dry steam as possible. Upon encountering the low-temperature surface of the tableware, condensation quickly forms. This condensation mixes, dilutes, and drips off the small amount of rinse water remaining on the tableware surface.

[0025] Process End and Subsequent Drying: Steam is introduced for a period of time (e.g., 3-6 minutes) and then stopped. At this point, the core method of this invention is complete. The ion concentration of residual liquid on the surface of the tableware has been significantly reduced. The equipment can then execute its built-in drying program (based on the drying heater 8), or the user can remove the tableware and allow it to air dry naturally, both methods achieving a low water stain effect.

[0026] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0027] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.
