Description

Technical Field

[0001] This utility model relates to the field of washing equipment technology, specifically a cleaning device with a deionized resin filter module, which is particularly suitable for scenarios such as baby bottle cleaners and dishwashers where it is necessary to avoid residual ion marks after cleaning. Background Technology

[0002] Cleaning equipment (such as bottle washers and dishwashers) is a common cleaning tool in daily life. Its core function is to remove stains from the surface of items through spraying, heating, and sterilization, ensuring hygiene. However, existing cleaning equipment generally suffers from the following technical deficiencies: Most existing cleaning equipment uses tap water directly as its cleaning source. Tap water contains cations such as calcium, magnesium, and sodium, as well as anions such as chloride, carbonate, and sulfate. During the cleaning process, these ions adhere to the surface of the items being cleaned, forming white limescale marks after the water evaporates. This problem is particularly prominent in baby bottle cleaners—the ionic marks left on the inner walls, necks, and nipples of baby bottles not only affect aesthetics but can also become a breeding ground for bacteria, increasing the risk of infants ingesting harmful substances. In dishwashers, ionic marks on the surfaces of tableware also affect the user experience and reduce the perceived cleaning effectiveness.

[0003] To address the aforementioned issues, existing technologies have proposed several improvement solutions: some high-end cleaning equipment uses RO reverse osmosis technology to achieve deionization, but it requires booster pumps and water storage tanks, resulting in complex structures, large footprints, and high costs, making it unsuitable for small household cleaning equipment; some cleaning equipment uses a cation exchange resin sodium salt regeneration system, which requires regular salt regeneration, making the operation cumbersome and prone to sodium salt residue, and the residual water droplets on the vessels will still leave ion imprints after evaporation. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a cleaning device with deionized resin filtration, which can effectively reduce the residual ion imprint after cleaning with ionized water in existing cleaning equipment, and the technical problems of poor convenience or poor effect of existing solutions.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A cleaning device with a deionized resin filter module includes a body, a washing chamber disposed within the body, a water supply system for supplying water to the washing chamber, and a control system for controlling the operation of the entire machine. The water supply system has a deionized resin filter module that can be detachably installed in the body. The deionized resin filter module is internally encapsulated with cation exchange resin and anion exchange resin.

[0006] To further optimize this technical solution, a pre-filter module that can be detachably installed on the machine body is also provided in the water supply system upstream of the deionized resin filter module. The pre-filter module is used to remove suspended solids and / or residual chlorine.

[0007] To further optimize this technical solution, a pre-filter material is provided upstream of the deionized resin in the deionized resin filtration module. The pre-filter material is used to remove suspended solids and / or residual chlorine.

[0008] To further optimize this technical solution, a water quality monitoring sensor is installed in the water supply system downstream of the deionized resin filtration module. The water quality monitoring sensor is electrically connected to the control system. When the measured water quality fails to meet the preset standard for ion removal, the control system issues a warning signal.

[0009] To further optimize this technical solution, the water quality monitoring sensor monitors the TDS value of the water.

[0010] To further optimize this technical solution, the cleaning equipment mentioned is a baby bottle cleaning machine.

[0011] To further optimize this technical solution, the cleaning equipment is a dishwasher.

[0012] Unlike existing technologies, this technical solution applies a deionized resin filter module containing cation exchange resin and anion exchange resin to cleaning equipment. By synergistically removing cations and anions from the water, it effectively prevents or significantly reduces the formation of ionic imprints from the source, improving cleaning effect and user experience. It is especially suitable for dishwashers and baby bottle cleaners that have stringent hygiene requirements for baby products.

[0013] Regarding ease of installation and maintenance: Both the deionized resin filter module and the pre-filter module (or material) feature a detachable design, allowing for direct replacement once the filter reaches the end of its lifespan, making operation simple. Combined with the water quality monitoring sensor's alert function, users do not need to manually test the water quality and can promptly know when to replace the filter, avoiding a decline in cleaning effectiveness due to filter failure.

[0014] The solution boasts strong adaptability: by removing suspended solids and / or residual chlorine through pre-filtration, it reduces wear and clogging of the deionized resin, extends the lifespan of the deionized resin filter module, and lowers user operating costs. It offers both independent and integrated pre-filtration solutions, allowing for flexible selection based on the size and structural design requirements of the cleaning equipment. It is suitable for both the complex water circuits of large dishwashers and the compact structure of small baby bottle washers, covering a variety of core application scenarios such as baby bottle washers and dishwashers.

[0015] Simple and reliable structure: Compared with RO reverse osmosis technology and sodium salt regeneration system of cation exchange resin, it occupies less space and has a lower overall cost. The overall technical solution does not require complicated auxiliary systems such as pressurization and regeneration, is suitable for domestic water supply conditions, has simple water circuit connection, low risk of leakage, controllable manufacturing cost, and is easy to mass-produce.

Detailed Implementation

[0018] A cleaning device with a deionized resin filter module includes a body, a washing chamber disposed within the body, a water supply system for supplying water to the washing chamber, and a control system for controlling the operation of the entire machine. The water supply system has a deionized resin filter module that can be detachably installed in the body. The deionized resin filter module is internally encapsulated with cation exchange resin and anion exchange resin.

[0019] The specific installation location of the deionized resin filter module includes, but is not limited to, the water inlet of the water supply system, the water tank, and the water inlet of the washing chamber. For easy disassembly and replacement, the preferred location for the deionized resin filter module is a non-rear part of the unit body, and it is preferred to use a quick-connect interface to connect to the water circuit.

[0020] Deionized resin filtration modules can adopt mixed bed or multi-bed structures. For cleaning scenarios requiring food contact grade, food-grade or higher-grade cation exchange resins and anion exchange resins should be selected. For example, water used for cleaning baby bottles must meet the standards for materials used in food contact (such as GB 4806.6-2016) to ensure the safety of the cleaning water and make it suitable for food contact scenarios such as baby bottles and tableware.

[0021] A preferred embodiment of the mixed bed structure: The shell of the deionization resin filtration module has a filling chamber. Cation exchange resin and anion exchange resin are uniformly mixed in a certain proportion and then filled into this filling chamber to form a mixed bed structure. Filter screens to prevent resin loss are respectively installed at the inlet and outlet of the deionization resin filtration module.

[0022] Preferred implementation of the multi-bed structure: The shell of the deion resin filter module is divided into upper and lower chambers by a porous partition. The upper chamber is filled with cation exchange resin and the lower chamber is filled with anion exchange resin. Water flows through the chamber from top to bottom, thus forming a multi-bed structure.

[0023] Figure 1 The following is a simplified version of the cleaning equipment described, with its water supply system operating as follows: Tap water enters through inlet pipe 1-4, is treated by deionized resin filter module 3, and then enters washing chamber 1-9; it is collected in water collection section 1-1, then pressurized by water pump 1-3, flows through heater 1-6, and is then delivered to spray arm 1-2 for spraying, before returning to water collection section 1-1 for circulation. After cleaning, the washing water is discharged by drain pump 1-10, and then the rinsing stage begins, completing the washing process.

[0024] To further optimize this embodiment, upstream of the deionized resin filter module, a pre-filter module that can be detachably installed on the machine body is also provided in the water supply system. The pre-filter module is used to remove suspended solids and / or residual chlorine.

[0025] The materials used in the pre-filtration module include, but are not limited to: PP filter material, activated carbon filter material, ultrafiltration filter material, and a tiered combination of the above filter materials.

[0026] To further optimize this embodiment, a pre-filter material is provided upstream of the deionized resin filter module. The pre-filter material is used to remove suspended solids and / or residual chlorine.

[0027] The pre-filter material and deionized resin are integrated into the deionized resin filter module, allowing users to easily replace all materials at once, making operation convenient.

[0028] To further optimize this embodiment, a water quality monitoring sensor is installed in the water supply system downstream of the deionized resin filtration module. The water quality monitoring sensor is electrically connected to the control system. When the measured water quality fails to meet the preset standard for ion removal, the control system issues a warning signal.

[0029] The parameters monitored by the water quality monitoring sensor can be TDS, EC, ORP, or other parameters that reflect ion residues. The specific form of the alert signals issued by the control system can be, but is not limited to, sound, light, display screen information, or mobile device information.

[0030] To further optimize this embodiment, the water quality monitoring sensor monitors the TDS value of the water.

[0031] For different washing equipment, set corresponding preset TDS standard values. For example, for a baby bottle cleaner, the TDS value can be set to 5 ppm, and for a dishwasher, the TDS value can be set to 10 ppm.

[0032] To further optimize this embodiment, the cleaning equipment is a baby bottle cleaning machine.

[0033] To further optimize this embodiment, the cleaning device is a dishwasher.

[0034] 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.

[0035] 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.
