Description

Technical Field

[0001] This utility model relates to the field of household appliances, and in particular to a scale-inhibiting device for a dishwasher, a scale-inhibiting water circuit system for a dishwasher, and a dishwasher. Background Technology

[0002] In existing technologies, dishwasher water softeners include structures such as a brine chamber, a resin chamber, and a solenoid valve to control water flow direction, making the internal structure of the dishwasher redundant and complex. On the one hand, this not only increases production costs but also occupies valuable internal space, limiting the dishwasher's potential for functional expansion and hindering improvements in overall performance and competitiveness. On the other hand, the resin regeneration process is complex, time-consuming, and inefficient. Furthermore, the resin regeneration process requires the discharge of high-concentration brine, which has a significant environmental impact. After regeneration, additional cleaning water is needed to rinse the resin and remove the brine, resulting in water waste. Utility Model Content

[0003] Therefore, it is necessary to address the problems of complex soft water structure in dishwashers, inefficient resin regeneration process in the soft water structure, and environmental unfriendliness by providing a scale inhibition device, a scale inhibition water circuit system, and a dishwasher.

[0004] A scale-inhibiting device for a dishwasher includes: a housing assembly; a top cover, the top cover being detachably mounted on the housing assembly, the housing assembly and the top cover forming a receiving cavity, the housing assembly and / or the top cover having a housing inlet and a housing outlet communicating with the receiving cavity; and a scale-inhibiting component, the scale-inhibiting component being detachably mounted on the housing assembly and / or the top cover and located in the receiving cavity, the scale-inhibiting component having a scale-inhibiting inlet and a placement cavity, the housing inlet, the scale-inhibiting inlet, the placement cavity and the housing outlet being sequentially connected.

[0005] The aforementioned device discloses a scale-inhibiting mechanism for a dishwasher. When the scale-inhibiting component becomes ineffective due to wear and tear, the user only needs to open the top cover and remove the component from the housing assembly for replacement. This significantly improves the convenience and efficiency of maintenance, while reducing maintenance costs and time. Structurally, the device has only one cavity for the scale-inhibiting component. Water flows sequentially through the housing inlet, scale-inhibiting inlet, cavity, and housing outlet to soften the water. This eliminates the need for a brine chamber and resin chamber in traditional devices, resulting in a simpler overall structure and a significant reduction in the number of parts required. This not only reduces manufacturing complexity, making the device more compact and adaptable to various installation spaces, especially suitable for environments with limited space, but also significantly reduces costs, providing users with a more economical option. Moreover, compared to traditional scale inhibition devices that use high-concentration brine to clean the resin, this application does not require the discharge of brine, thus avoiding environmental pollution and being more environmentally friendly. In addition, without a rinsing process, it achieves efficient scale inhibition while saving water, effectively shortening the entire washing cycle time, improving energy efficiency, and bringing users a more convenient, greener, and more efficient user experience.

[0006] In one embodiment, the scale inhibition assembly includes a scale inhibition tank and scale inhibition components. The scale inhibition tank is detachably mounted on the housing assembly and has a mounting cavity. The scale inhibition components are mounted on the scale inhibition tank and located within the mounting cavity. The scale inhibition tank can be easily removed from the mounting cavity, meaning that when the scale inhibition components reach the end of their service life or their performance deteriorates, the user can conveniently remove the tank for treatment. Multiple scale inhibition components are positioned within the mounting cavity, enabling comprehensive and more efficient scale inhibition. This modular design greatly improves maintenance efficiency. No professional personnel or complex tools are required; ordinary users can complete the operation themselves, reducing time and labor costs. Furthermore, while ensuring scale inhibition performance, the number and type of scale inhibition components can be flexibly adjusted for different water quality conditions, achieving personalized customization. Moreover, the scale inhibition tank is independently mounted, so maintenance or replacement will not affect other parts of the housing assembly, avoiding a situation where a change in one part affects the whole, further reducing maintenance difficulty and risk, ensuring the device is always in optimal operating condition, and providing users with a more worry-free and efficient user experience.

[0007] In one embodiment, there are multiple scale-inhibiting inlets, which are located at one end of the scale-inhibiting tank near the housing inlet. By placing multiple scale-inhibiting inlets at one end of the scale-inhibiting tank near the housing inlet, the water flow into the mounting cavity can be more even. The water flow is no longer concentrated in one place, but flows in from multiple locations, avoiding situations where the local water flow is too large or too small. This fully utilizes the space inside the mounting cavity, ensuring omnidirectional contact with multiple scale-inhibiting components, greatly improving scale-inhibiting efficiency, and allowing each scale-inhibiting component to function efficiently.

[0008] In one embodiment, the scale inhibition component has a scale inhibition outlet communicating with the mounting cavity, and the shell inlet, scale inhibition inlet, mounting cavity, scale inhibition outlet, and shell outlet are sequentially connected. By sequentially connecting the shell inlet, scale inhibition inlet, mounting cavity, scale inhibition outlet, and shell outlet, a scientifically ordered water flow path is formed. This design ensures that the water flows smoothly and efficiently through the scale inhibition component along a predetermined route. The water enters from the shell inlet, is precisely guided into the mounting cavity through the scale inhibition inlet, and fully contacts the scale inhibition component inside the cavity to complete impurity filtration and scale treatment. It then flows out through the scale inhibition outlet and finally exits through the shell outlet. Simultaneously, multiple scale inhibition outlets are located on the side wall of the scale inhibition tank, optimizing the water flow path within the tank. After the water has fully passed through the scale inhibition component and completed scale inhibition treatment, it can quickly flow out from multiple outlets on the side wall of the tank, reducing the water's residence time within the tank and lowering the risk of the treated water being re-contaminated or developing secondary scale. Moreover, this multi-inlet and multi-outlet design improves the processing capacity of the device without changing the overall tank volume, making the entire scale inhibition process smoother and more efficient. Structurally, multiple inlets and outlets distribute the water flow pressure, reducing the load on a single interface and extending the service life of the scale inhibition tank and the entire scale inhibition assembly.

[0009] In one embodiment, a flow gap is formed between the scale-inhibiting tank and the top cover, and the housing inlet, the scale-inhibiting inlet, the mounting cavity, the flow gap, and the housing outlet are sequentially connected. By creating a flow gap between the scale-inhibiting tank and the top cover, and ensuring the sequential connection of the housing inlet, scale-inhibiting inlet, mounting cavity, flow gap, and housing outlet, the water flowing from the mounting cavity can be more evenly distributed, avoiding pressure unevenness caused by localized water flow concentration, reducing direct impact on the housing outlet, ensuring stable pressure throughout the water system, reducing component wear caused by drastic water flow fluctuations, and extending the device's service life.

[0010] In one embodiment, the scale-inhibiting tank is made of filter material, and the shell inlet, scale-inhibiting inlet, mounting cavity, tank wall, and shell outlet are sequentially connected. By using filter material to make the scale-inhibiting tank, and with the sequential connection of the shell inlet, scale-inhibiting inlet, mounting cavity, tank wall, and shell outlet, the performance of the scale-inhibiting device is greatly enhanced. The tank made of filter material can actively participate in the interception of scale and impurities. Water enters from the shell inlet, passes through the scale-inhibiting inlet, and enters the mounting cavity. After interacting with the scale-inhibiting components inside the cavity, residual impurities are again captured by the filter material during the penetration of the tank wall, achieving dual filtration and significantly improving the water purification effect.

[0011] In one embodiment, the housing assembly includes a main housing and an annular housing. The annular housing is disposed on the main housing, the top cover is disposed on the main housing, and the scale inhibitor assembly is disposed on the main housing. The annular housing surrounds the scale inhibitor assembly, and the main housing and the top cover together form the receiving cavity. The main housing and / or the top cover have a housing inlet and a housing outlet. By tightly fitting the annular housing around the main housing and fitting it snugly to the scale inhibitor assembly, not only is a stable support provided for the scale inhibitor assembly, but it also effectively prevents displacement due to water flow impact or external vibration during device operation, ensuring that the scale inhibitor assembly is always in optimal working condition. When it is necessary to remove or place the scale inhibitor assembly, the annular housing plays a crucial role in precise positioning. Its carefully designed structure or markings provide clear guidance for operators, enabling the removal and installation of the scale inhibitor assembly to be completed accurately. This greatly simplifies the maintenance process and reduces the risk of installation errors or component damage due to inaccurate positioning.

[0012] In one embodiment, the main housing has a housing outlet. By providing a housing outlet on the main housing, the discharge speed and flow rate of the treated water can be precisely controlled, ensuring stable water pressure throughout the device and guaranteeing the smooth progress of the scale inhibition process. In terms of device layout, the outlet is located on the main housing, making the entire water flow path simpler and smoother, optimizing the utilization of internal space, and reducing the complexity of pipe connections.

[0013] In one embodiment, the top cover has multiple water outlets for the housing. By providing multiple water outlets on the top cover, the performance and user experience of the scale inhibition device can be significantly improved. Multiple outlets greatly enhance drainage efficiency, allowing treated water to be discharged quickly, reducing its residence time within the device, further ensuring stable water pressure, and facilitating efficient operation of the scale inhibition process. From a device layout perspective, this design disperses the water flow, optimizes the overall water flow path, and makes more rational use of space.

[0014] In one embodiment, a sealing ring is further included, which is sleeved on the scale inhibitor assembly and sandwiched between the scale inhibitor assembly and the annular shell. By sleeved on the scale inhibitor assembly and sandwiched between the scale inhibitor assembly and the annular shell, water leakage can be effectively prevented, forming a tight sealing barrier between the scale inhibitor assembly and the annular shell. This ensures that the water flow strictly follows the predetermined path of the shell inlet, scale inhibitor inlet, mounting cavity, tank wall of the scale inhibitor tank, and shell outlet, avoiding water waste and device performance degradation caused by leakage, and ensuring the sealing and operational stability of the entire water system.

[0015] In one embodiment, the top cover includes a top cover body and a snap fastener. The top cover body is disposed on the housing assembly, and the snap fastener is disposed on the top cover body and engages with the housing assembly. By securely mounting the top cover body on the housing assembly, a strong protective barrier is formed, effectively preventing dust and foreign objects from entering the device and interfering with the normal scale inhibition process. This protects the internal precision components from external environmental corrosion and extends the device's service life. The snap fastener, mounted on the top cover body and engaging with the housing assembly, is an ingenious design that greatly enhances the ease of opening and closing. Users can easily open and close the top cover without any tools, facilitating routine inspections, maintenance, and replacement of scale inhibition components. Simultaneously, the tight engagement provided by the snap fastener ensures a stable connection between the top cover and the housing assembly. Even when the device is subjected to vibration or water flow impact, the top cover will not accidentally loosen, maintaining the overall sealing of the device and ensuring stable and reliable operation of the scale inhibition device, providing users with an efficient, convenient, and reassuring user experience.

[0016] In one embodiment, the scale inhibition assembly is provided with a scale inhibition outlet. The scale inhibition assembly divides the receiving cavity into a first buffer cavity and a second buffer cavity. The housing inlet, the first buffer cavity, the scale inhibition inlet, the placement cavity, the scale inhibition outlet, the second buffer cavity, and the housing outlet are sequentially connected. By using the scale inhibition assembly to divide the receiving cavity into a first buffer cavity and a second buffer cavity, and with the housing inlet, the first buffer cavity, the scale inhibition inlet, the placement cavity, the scale inhibition outlet, the second buffer cavity, and the housing outlet sequentially connected, this design greatly improves the performance of the scale inhibition device. The first buffer cavity can effectively reduce the impact force when water flows into the scale inhibition assembly, avoiding impact damage to the scale inhibition component caused by high-speed water flow, while ensuring uniform water flow distribution, creating stable conditions for subsequent entry into the placement cavity to fully contact the scale inhibition material. After the water has completed scale inhibition treatment in the placement cavity, it enters the second buffer cavity through the scale inhibition outlet. The second buffer cavity further buffers and guides the water flow, ensuring that the water flows smoothly towards the housing outlet, preventing water flow fluctuations from affecting the operation of downstream equipment. The dual buffer chambers also balance the water pressure inside the device, preventing excessively high or low local pressure, ensuring stable water flow through the scale inhibitor components, and extending the overall service life of the device.

[0017] The second aspect of this application discloses a scale-inhibiting water circuit system for a dishwasher, the scale-inhibiting water circuit system of the dishwasher comprising: the scale-inhibiting device of the dishwasher as described above; a water inlet valve body, the water inlet valve body having a water inlet valve inlet and a water inlet valve outlet; a breather assembly, the breather assembly having a breather inlet and a breather outlet; a cup body, the cup body having a cup body inlet, the water inlet valve inlet, the water inlet valve outlet, the breather inlet, the breather outlet, the housing inlet, the scale-inhibiting inlet, the mounting cavity, the housing outlet, and the cup body inlet being sequentially connected.

[0018] The second aspect disclosed above discloses a scale-inhibiting water system for a dishwasher. The scale-inhibiting device, as the core component, effectively removes impurities and scale from the water through its unique structure. The inlet valve plays a crucial role in water flow control. The inlet of the inlet valve is connected to an external water source, and the outlet of the inlet valve precisely regulates the water flow and pressure, ensuring stable and suitable water entering the system, laying a good foundation for subsequent processing. The breather inlet is connected to the inlet valve outlet, balancing the internal pressure of the system and preventing water flow obstruction or device damage due to abnormal pressure. The cup body, as the terminal component, has its inlet connected to the outlet of the scale-inhibiting device housing, receiving the purified water after multiple treatments. The entire system's water flow path is scientifically and rationally designed. Starting from the inlet of the inlet valve, through the coordinated processing of various components, the purified water is finally delivered to the cup body, ensuring users receive high-quality water. Moreover, the system has a compact structure and is suitable for various scenarios, whether for daily household water use or small commercial establishments, efficiently meeting scale-inhibiting water needs and providing users with a convenient and reliable water experience.

[0019] In one embodiment, the water inlet of the inlet valve and the water inlet of the breather are connected by a pipe, the water outlet of the breather and the water inlet of the housing are connected by a pipe, and the water outlet of the housing and the water inlet of the cup are connected by a pipe. Connecting the water outlet of the inlet valve and the water inlet of the breather through a pipe provides a smooth transition channel for the water flow. This connection method ensures that the water flow, after precise control by the inlet valve, can safely and efficiently reach the breather assembly, guaranteeing the smooth operation of the system pressure balancing process. The robustness of the pipe connection reduces the risk of water leakage, maintains stable water flow, and avoids impact on subsequent components due to water flow fluctuations. Connecting the water outlet of the breather and the water inlet of the housing through a pipe seamlessly connects the water flow, after pressure balancing and gas treatment, to the scale inhibition device. This connection allows the water flow to enter the scale inhibition process continuously, reducing water flow loss, improving scale inhibition efficiency, and ensuring the stable operation of the scale inhibition device. Connecting the water outlet of the housing and the water inlet of the cup through a pipe ensures that the water, after multiple purification stages, can be delivered to the final cup in optimal condition. Users can obtain clean water, and the pipe connection is convenient for disassembling, cleaning or replacing the cup body later. Maintenance is simple and convenient, which comprehensively improves the reliability and practicality of the entire scale-inhibiting water circuit system and provides users with better water services.

[0020] In one embodiment, the water inlet of the inlet valve and the water inlet of the breather are connected by a pipe, the water outlet of the breather and the water inlet of the housing are connected by a pipe, and multiple water outlets of the housing and the water inlet of the cup are connected. By connecting the water outlet of the inlet valve and the water inlet of the breather through a pipe, a smooth transition of water flow is achieved. This connection ensures that the water flow after precise control by the inlet valve can flow safely and efficiently into the breather assembly, allowing the system pressure balancing process to proceed smoothly. The robustness of the pipe connection effectively reduces the risk of water leakage, maintains stable water flow, and avoids impact on subsequent components due to water flow fluctuations. The water outlet of the breather and the water inlet of the housing are connected by a pipe, allowing the water flow after pressure balancing and gas treatment to seamlessly connect to the scale inhibition device. The direct connection of multiple water outlets of the housing and the water inlet of the cup significantly improves the water transmission efficiency, allowing the purified water to be delivered to the terminal cup in the fastest and best condition.

[0021] In one embodiment, the breather assembly includes a breather body, a breather flow meter, and a breather inlet valve. Both the breather flow meter and the breather inlet valve are mounted on the breather body, which has a breather inlet, a breather outlet, and air inlet / outlet ports. By mounting the breather flow meter on the breather body, real-time and accurate water flow data can be monitored, allowing users to have a clear understanding of the water flow entering the system, facilitating timely detection of abnormal water flow and ensuring stable system operation. The breather inlet valve, also mounted on the breather body, allows for flexible adjustment of the water flow. Based on actual water demand and system operating status, the amount of water entering the scale inhibition device can be precisely adjusted, preventing excessive or insufficient water flow from affecting the scale inhibition effect and effectively improving the adaptability and reliability of the entire system. Furthermore, the air inlet / outlet ports on the breather body play an indispensable role. They automatically balance internal pressure during system operation, preventing water flow obstruction or equipment damage due to pressure imbalance.

[0022] A third aspect of this application discloses a dishwasher, which includes: the scale-inhibiting water system of the dishwasher described above; and a dishwasher body, wherein the scale-inhibiting water system is disposed on the dishwasher body.

[0023] The third aspect of this application discloses a dishwasher in which a scale-inhibiting water system is installed on the dishwasher body. This system effectively removes impurities and scale from the water, ensuring the cleanliness of the water flowing into the dishwasher and significantly improving the cleaning effect on tableware, leaving it sparkling clean. Simultaneously, it reduces scale buildup in the dishwasher's internal pipes, heating elements, and other components, greatly extending the dishwasher's lifespan and reducing the cost of frequent repairs or parts replacements.

[0042] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0043] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0044] The scale-inhibiting device, scale-inhibiting water system, and dishwasher of some embodiments of the present invention are described below with reference to the accompanying drawings.

[0045] Example 1

[0046] like Figures 1 to 9As shown, this embodiment discloses a scale inhibition device for a dishwasher, including: a housing assembly 1; a top cover 2, which is detachably mounted on the housing assembly 1, the housing assembly 1 and the top cover 2 forming a receiving cavity 101, the housing assembly 1 and / or the top cover 2 having a housing inlet 102 and a housing outlet 103 communicating with the receiving cavity 101; and a scale inhibition component 3, which is detachably mounted on the housing assembly 1 and / or the top cover 2 and located in the receiving cavity 101, the scale inhibition component 3 having a scale inhibition inlet 301 and a placement cavity 303, the housing inlet 102, the scale inhibition inlet 301, the placement cavity 303 and the housing outlet 103 being sequentially connected.

[0047] This application discloses a scale-inhibiting device for a dishwasher. When the scale-inhibiting component 3 loses its effectiveness due to wear and tear, the user only needs to open the top cover 2 and remove the scale-inhibiting component 3 from the housing assembly 1 for replacement, greatly improving the convenience and efficiency of maintenance and reducing maintenance costs and time. Structurally, the device has only one housing cavity 303 for the scale-inhibiting component 3, which allows water to flow sequentially through the housing inlet 102, the scale-inhibiting inlet 301, the housing cavity 303, and the housing outlet 103 to soften the water. This eliminates the need for a brine chamber and a resin chamber in traditional devices, making the overall structure simpler and significantly reducing the number of required parts. This not only reduces the complexity of manufacturing, making the overall device more compact and adaptable to various installation spaces, especially suitable for environments with limited space, but also significantly reduces costs, providing users with a more economical option. Moreover, compared to traditional scale inhibition devices that use high-concentration brine to clean the resin, this application does not require the discharge of brine, thus avoiding environmental pollution and being more environmentally friendly. In addition, without a rinsing process, it achieves efficient scale inhibition while saving water, effectively shortening the entire washing cycle time, improving energy efficiency, and bringing users a more convenient, greener, and more efficient user experience.

[0048] like Figure 1 , Figure 3 and Figure 5As shown, in addition to the features of the above embodiments, this embodiment further defines the following: the scale inhibition assembly 3 includes a scale inhibition tank 31 and scale inhibition components 32. The scale inhibition tank 31 is detachably mounted on the housing assembly 1. The scale inhibition tank 31 has a mounting cavity 303, and the scale inhibition components 32 are mounted on the scale inhibition tank 31 and located in the mounting cavity 303. The scale inhibition tank 31 can be easily disassembled from the receiving cavity 101, meaning that when the scale inhibition components 32 reach the end of their service life or their performance deteriorates, the user can easily remove the tank for treatment. Multiple scale inhibition components 32 are mounted in the mounting cavity 303, enabling comprehensive and more efficient scale inhibition. This modular design greatly improves maintenance efficiency. No professional personnel or complex tools are required; ordinary users can complete the operation themselves, reducing time and labor costs. Furthermore, while ensuring scale inhibition performance, the number and type of scale inhibition components 32 can be flexibly adjusted for different water quality conditions, achieving personalized customization. Moreover, the scale inhibition tank 31 is independently set up, so that when it is inspected or replaced, it will not affect other parts of the shell assembly 1, avoiding the situation where a change in one part affects the whole, further reducing the difficulty and risk of maintenance, ensuring that the device is always in the best operating condition, and bringing users a more worry-free and efficient user experience.

[0049] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of scale-inhibiting inlets 301 is multiple, and the multiple scale-inhibiting inlets 301 are arranged at one end of the scale-inhibiting tank 31 near the shell inlet 102. By arranging multiple scale-inhibiting inlets 301 at one end of the scale-inhibiting tank 31 near the shell inlet 102, the water flow can enter the mounting cavity 303 more evenly. The water flow is no longer concentrated in one place, but flows in from multiple positions, avoiding the situation of excessive or insufficient local water flow, making full use of the space inside the mounting cavity, and making full contact with multiple scale-inhibiting components 32, greatly improving the scale-inhibiting efficiency, and allowing each scale-inhibiting component to play a high-efficiency role.

[0050] like Figure 1 and Figure 3As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the scale inhibitor component 3 has a scale inhibitor outlet 302 communicating with the mounting cavity 303, and the housing inlet 102, scale inhibitor inlet 301, mounting cavity 303, scale inhibitor outlet 302, and housing outlet 103 are sequentially connected. By sequentially connecting the housing inlet 102, scale inhibitor inlet 301, mounting cavity 303, scale inhibitor outlet 302, and housing outlet 103, a scientifically ordered water flow path is formed. This design ensures that the water flow can smoothly and efficiently pass through the scale inhibitor component 3 along a predetermined route. The water flows in from the housing inlet 102, is precisely guided into the mounting cavity 303 through the scale inhibitor inlet 301, and fully contacts the scale inhibitor in the cavity to complete impurity filtration and scale treatment, then flows out through the scale inhibitor outlet 302, and finally is discharged through the housing outlet 103. Meanwhile, multiple scale-inhibiting outlets 302 are located on the side wall of the scale-inhibiting tank 31, optimizing the water flow path within the tank. After the water has fully passed through the scale-inhibiting component 32 and completed the scale-inhibiting treatment, it can quickly flow out from multiple outlets on the side wall of the tank, reducing the water's residence time within the tank and lowering the risk of the treated water being re-contaminated or developing secondary scale. Moreover, this multi-inlet and multi-outlet design improves the processing capacity of the device without changing the overall tank volume, making the entire scale-inhibiting process smoother and more efficient. Structurally, multiple inlets and outlets distribute the water flow pressure, reducing the load on a single interface and extending the service life of the scale-inhibiting tank 31 and the entire scale-inhibiting component 3.

[0051] like Figure 1 , Figure 3 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a flow gap is formed between the scale inhibitor tank 31 and the top cover 2, and the shell inlet 102, scale inhibitor inlet 301, mounting cavity 303, flow gap, and shell outlet 103 are sequentially connected. By forming a flow gap between the scale inhibitor tank 31 and the top cover 2, and coordinating the sequential connection of the shell inlet 102, scale inhibitor inlet 301, mounting cavity 303, flow gap, and shell outlet 103, the water flowing out of the mounting cavity 303 can be more evenly diffused, avoiding uneven pressure caused by localized water flow concentration, reducing direct impact on the shell outlet 103, ensuring stable pressure throughout the water system, reducing component wear caused by drastic water flow fluctuations, and extending the service life of the device.

[0052] like Figure 1 , Figure 3 and Figure 5As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the scale-inhibiting tank 31 is made of filter material, and the shell inlet 102, the scale-inhibiting inlet 301, the mounting cavity 303, the tank wall of the scale-inhibiting tank 31, and the shell outlet 103 are sequentially connected. By using filter material to make the scale-inhibiting tank 31, and with the sequential connection of the shell inlet 102, the scale-inhibiting inlet 301, the mounting cavity 303, the tank wall of the scale-inhibiting tank 31, and the shell outlet 103, the performance of the scale-inhibiting device is greatly enhanced. The tank made of filter material can actively participate in the interception of scale and impurities. Water enters from the shell inlet 102, passes through the scale-inhibiting inlet 301, and enters the mounting cavity 303. After interacting with the scale-inhibiting components in the cavity, residual impurities are captured again by the filter material during the process of penetrating the tank wall, achieving dual filtration and significantly improving the water purification effect.

[0053] like Figure 1 , Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further defines: the housing assembly 1 includes a main housing 11 and an annular housing 12, the annular housing 12 is disposed on the main housing 11, the top cover 2 is disposed on the main housing 11, the scale inhibitor assembly 3 is disposed on the main housing 11, the annular housing 12 is disposed around the scale inhibitor assembly 3, and the main housing 11 and the top cover 2 form a receiving cavity 101. The main housing 11 and / or the top cover 2 are provided with a housing inlet 102 and a housing outlet 103. By distributing the annular housing 12 around the main housing 11 and tightly fitting it to the scale inhibitor assembly 3, not only is a stable support provided for the scale inhibitor assembly 3, but it can also effectively prevent its displacement due to water flow impact or external vibration during device operation, ensuring that the scale inhibitor assembly 3 is always in the best working condition. When it is necessary to remove or place the scale inhibitor assembly 3, the annular housing 12 plays a crucial role in precise positioning. Its carefully designed structure or markings can provide clear guidance for operators, enabling the removal and installation of the scale inhibitor assembly 3 to be completed accurately. This greatly simplifies the maintenance process and reduces the risk of installation errors or component damage due to inaccurate positioning.

[0054] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the main housing 11 is provided with a housing outlet 103. By providing a housing outlet 103 on the main housing 11, the discharge speed and flow rate of the treated water can be precisely controlled, ensuring stable water pressure throughout the device and guaranteeing the smooth progress of the scale inhibition process. In terms of device layout, the outlet is located on the main housing 11, making the entire water flow path simpler and smoother, optimizing the utilization of internal space, and reducing the complexity of pipe connections.

[0055] like Figure 2 and Figure 9As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the top cover 2 has a housing outlet 103, and the number of housing outlets 103 is multiple. By providing multiple housing outlets 103 on the top cover 2, the performance and user experience of the scale inhibition device can be significantly improved. Multiple outlets can greatly improve drainage efficiency, allowing the treated water to be discharged quickly, reducing the residence time in the device, further ensuring stable water pressure, and helping the scale inhibition process to operate efficiently. From the perspective of device layout, this design allows the water flow to be dispersed and discharged, optimizing the overall water flow path and making more reasonable use of space.

[0056] like Figure 1 , Figure 3 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further includes a sealing ring 8, which is sleeved on the scale inhibitor component 3 and sandwiched between the scale inhibitor component 3 and the annular shell 12. By sleeved on the scale inhibitor component 3 and sandwiched between the scale inhibitor component 3 and the annular shell 12, water leakage can be effectively prevented, forming a tight sealing barrier between the scale inhibitor component 3 and the annular shell 12. This ensures that the water flow strictly follows the predetermined path of the shell inlet 102, the scale inhibitor inlet 301, the mounting cavity 303, the tank wall of the scale inhibitor tank 31, and the shell outlet 103, avoiding water waste and device performance degradation caused by leakage, and ensuring the sealing and operational stability of the entire water system.

[0057] like Figure 1 , Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: it also includes an inner liner bottom plate 4, and the shell assembly 1 also includes a sealing element 13 and a fixing element 14. Both the sealing element 13 and the fixing element 14 are disposed on the main shell 11, and a portion of the inner liner bottom plate 4 is sandwiched between the sealing element 13 and the fixing element 14. By having the sealing element 13 disposed on the main shell 11 and tightly fitting the inner liner bottom plate 4, water leakage is effectively prevented, ensuring that the water flow in the receiving cavity 101 circulates in a predetermined path, avoiding water waste and device performance degradation caused by leakage, and greatly improving the sealing performance and operational stability of the device. The fixing element 14 is also installed on the main shell 11, firmly fixing the main shell 11 and preventing it from shaking or shifting under the impact of water flow, ensuring the stability of the internal structure, and making the collaborative work between the components smoother.

[0058] like Figure 1 , Figure 2 and Figure 4As shown, in addition to the features of the above embodiments, this embodiment further defines: the top cover 2 includes a top cover body 21 and a buckle 22. The top cover body 21 is disposed on the housing assembly 1, and the buckle 22 is disposed on the top cover body 21 and is fastened to the housing assembly 1. By securely disposing the top cover body 21 on the housing assembly 1, a good protective barrier is formed, effectively preventing dust and foreign objects from entering the device, preventing them from interfering with the normal scale inhibition process, protecting the internal precision components from external environmental corrosion, and extending the service life of the device. The buckle 22 is disposed on the top cover body 21 and fastened to the housing assembly 1. This ingenious design greatly improves the ease of opening and closing. Users can control the buckle 22 with simple operation without the need for any tools, easily opening and closing the top cover 2, facilitating daily inspection, maintenance, and replacement of the scale inhibition component 3 inside the device. Meanwhile, the tight fastening effect provided by the buckle 22 ensures the stability of the connection between the top cover and the housing assembly 1. Even when the device is subjected to vibration or water flow impact, it can ensure that the top cover will not be accidentally loosened, maintain the overall sealing of the device, ensure the stable and reliable operation of the scale inhibition device, and bring users an efficient, convenient and safe user experience.

[0059] like Figure 3 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the scale inhibition component 3 is provided with a scale inhibition outlet 302, and the scale inhibition component 3 divides the receiving cavity 101 into a first buffer cavity 1011 and a second buffer cavity 1012. The housing inlet 102, the first buffer cavity 1011, the scale inhibition inlet 301, the placement cavity 303, the scale inhibition outlet 302, the second buffer cavity 1012, and the housing outlet 103 are sequentially connected. By using the scale inhibition component 3 to divide the receiving cavity 101 into the first buffer cavity 1011 and the second buffer cavity 1012, and with the housing inlet 102, the first buffer cavity 1011, the scale inhibition inlet 301, the placement cavity 303, the scale inhibition outlet 302, the second buffer cavity 1012, and the housing outlet 103 sequentially connected, this design greatly improves the performance of the scale inhibition device. The first buffer chamber 1011 effectively reduces the impact force of water flowing into the scale inhibitor component 3, preventing high-speed water flow from damaging the scale inhibitor. It also ensures uniform water flow, creating stable conditions for subsequent entry into the mounting chamber 303 to fully contact the scale inhibitor material. After scale inhibition treatment in the mounting chamber 303, the water flows through the scale inhibitor outlet 302 into the second buffer chamber 1012. The second buffer chamber 1012 further buffers and guides the water flow, ensuring a stable flow towards the shell outlet 103, preventing fluctuations in water flow from affecting downstream equipment operation. The dual buffer chambers also balance the internal water pressure, preventing excessively high or low local pressure, ensuring stable water flow through the scale inhibitor component 3, and extending the overall service life of the device.

By connecting the water inlet valve outlet 502 and the breather inlet 601 by a pipe, a smooth transition channel is provided for the water flow. This connection method ensures that the water flow after precise control by the water inlet valve body can safely and efficiently reach the breather components, ensuring the smooth operation of the system pressure balancing process. The stability of the pipe connection reduces the risk of water leakage, maintains water flow stability, and avoids impact on subsequent components due to water flow fluctuations. The breather outlet 602 and the housing inlet 102 are connected by a pipe, seamlessly connecting the water flow after pressure balancing and gas treatment to the scale inhibition device. This connection allows the water flow to enter the scale inhibition process continuously, reducing water flow loss, improving scale inhibition efficiency, and ensuring the stable operation of the scale inhibition device. The outlet 103 of the housing and the inlet 701 of the cup are connected by a pipe, so that the water, after being purified through multiple stages, can be delivered to the terminal cup 7 in optimal condition. Users can obtain clean water, and the pipe connection facilitates the disassembly, cleaning, or replacement of the cup 7 in the future, making maintenance simple and convenient. This comprehensively improves the reliability and practicality of the entire scale-inhibiting water circuit system, providing users with a better water service.

[0064] like Figure 1 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the water inlet valve outlet 502 and the breather inlet 601 are connected by a pipe; the breather outlet 602 and the housing inlet 102 are connected by a pipe; and multiple housing outlets 103 and cup inlets 701 are connected. By connecting the water inlet valve outlet 502 and the breather inlet 601 by a pipe, a smooth transition of water flow is achieved. This connection ensures that the water flow after precise control by the water inlet valve body can flow safely and efficiently into the breather assembly, allowing the system pressure balancing process to proceed smoothly. The stability of the pipe connection effectively reduces the risk of water leakage, maintains water flow stability, and avoids impact on subsequent components due to water flow fluctuations. The breather outlet 602 and the housing inlet 102 are connected by a pipe, allowing the water flow after pressure balancing and gas treatment to seamlessly connect to the scale inhibition device. Multiple shell outlets 103 and cup inlet 701 are directly connected. This design greatly improves the water transmission efficiency, allowing water that has been purified through multiple layers to be delivered to the terminal cup in the fastest and best condition.

[0065] like Figure 7As shown, in addition to the features of the above embodiments, this embodiment further defines: the breather assembly 6 includes a breather body 61, a breather flow meter 62, and a breather inlet valve 63. Both the breather flow meter 62 and the breather inlet valve 63 are mounted on the breather body 61. The breather body 61 has a breather inlet 601, a breather outlet 602, and an air inlet / outlet port 603. By mounting the breather flow meter 62 on the breather body 61, water flow data can be monitored accurately in real time, allowing users to have a clear understanding of the water flow entering the system, facilitating timely detection of water flow abnormalities, and ensuring stable system operation. The breather inlet valve 63 is also mounted on the breather body 61, allowing for flexible adjustment of the water flow. Based on actual water demand and system operating status, the amount of water entering the scale inhibition device can be precisely adjusted, avoiding the scale inhibition effect being affected by excessive or insufficient water flow, effectively improving the adaptability and reliability of the entire system. Furthermore, the air inlet / outlet port 603 on the breather body 61 plays an indispensable role. It can automatically balance the internal pressure during system operation to prevent water flow obstruction or equipment damage caused by pressure imbalance.
