Abstract
Description
Technical Field
[0001] This invention relates to the field of water treatment, and in particular to a display device and a water softener having said display device. Background Technology
[0002] A water softener is a device that softens water by reducing the calcium and magnesium ion content through physical or chemical methods. A water softener mainly consists of components such as a control valve, display device, resin tank, brine tank, and sodium ion exchange resin. Existing water softener display devices primarily employ three setting methods: The first type of display device is a fixed or embedded structure, which is directly fixed to the surface of the water softener. Although this method is simple in structure, it occupies external operating space. Users need to bend over or move to a specific angle to observe the displayed information, resulting in low space utilization and inconvenient operation.
[0003] The second type of display device is a movable structure with accessories. Position adjustment is achieved by adding external connecting parts such as rollers and guide rails between the display device and the machine body. Although this improves the ease of operation, it introduces additional materials, resulting in a wide variety of parts, high costs, and complex assembly processes. The improvement in production efficiency is limited, and the accessories are prone to wear and jamming after long-term use.
[0004] The third type of display device is an external structure, which sets up the display device independently of the host through wired or wireless means. Wired connection takes up limited home space and hinders users' daily living activities; wireless connection requires the addition of a communication module, which greatly increases hardware costs and the signal stability is affected by the environment. At the same time, the external structure destroys the overall product integrity and affects the aesthetics of the home. Summary of the Invention
[0005] The summary of this invention introduces a series of simplified concepts, all of which are simplifications of existing technologies in the field, and will be further explained in detail in the detailed description section. This summary is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.
[0006] The technical problem to be solved by the present invention is to address the shortcomings of the three existing display device settings for water softeners. The present invention provides a display device that occupies little space, has a higher space utilization rate, is easy to operate, has low manufacturing cost, and is easy to assemble.
[0007] To solve the above-mentioned technical problems, the present invention provides a display device applied to a water softener, comprising: The back plate has a track groove and a track baffle along the inner edge of the two track grooves on its bottom concave plane. The track groove and the track baffle together form a "U" shaped track. A panel is mounted on a back panel and connected to the back panel to form an accommodating space; The display panel is disposed within the accommodating space; The top cover has a salt filling port and two "I"-shaped tracks on its top surface along its length. The U-shaped track and the straight track slide together, allowing the display device to slide relative to the top cover and at least cover the closed position of the salt filling port or expose the open position of the salt filling port.
[0008] Preferably, the display device is further improved such that the track baffle of the back plate is provided with symmetrically arranged baffle openings, and the "I"-shaped track of the top cover is inserted into the "U"-shaped track through the baffle openings.
[0009] Preferably, the display device is further improved by providing multiple buckles and / or multiple slots inside the back panel, and the display panel is fixed between the back panel and the front panel by the buckles and / or slots.
[0010] Preferably, the display device is further improved by having multiple stepped pillars inside the back panel, and through holes on the display panel, so that the display panel can be interchangeably assembled through the cooperation of the through holes and the stepped pillars.
[0011] Preferably, the display device is further improved such that a raised outer cover is provided at one end of the back plate, and the outer cover is located above the salt filling port when the salt filling port is closed, and the outer cover contacts the edge of the salt filling port to form a seal; The back plate has two recesses at the other end, and the two "I"-shaped tracks of the top cover have protrusions on their outer sides. When the salt filling port is open, the recesses and protrusions engage and are positioned.
[0012] Preferably, the display device is further improved by including: a ribbon cable and a silicone plug, wherein an opening is provided on one side of the back plate, the silicone plug is provided with a slot and is engaged with the opening, and the ribbon cable passes through the silicone plug and is connected to the display panel.
[0013] Preferably, the display device is further improved in that the outer surface of the panel is provided with a recessed plane, and the recessed plane is provided with a display window and an operation through hole, and the display screen and buttons of the display panel are respectively aligned with the display window and the operation through hole.
[0014] The present invention provides a water softener having the display device described in any one of the above claims.
[0015] The display device provided by the present invention has at least the following technical advantages compared to the prior art; 1. In the existing technology, fixed devices require additional operating space, external devices protrude from the surface of the machine body, and auxiliary devices require external track space, none of which can achieve "zero external occupation" of the track structure.
[0016] This invention employs a recessed, concealed track design, directly molding the track groove and baffle onto the exterior of the back panel to form a "U"-shaped track, which then slides into the "I"-shaped track of the top cover. This structure completely hides the track system between the device and the top cover, occupying no external space. Through its recessed integrated design, this invention allows the display device to sink into the concave top surface of the top cover, resulting in a highly integrated structure and reduced space occupancy.
[0017] Therefore, the present invention provides a significant improvement in the structural compactness and space utilization of the display device.
[0018] 2. Existing technologies using separate accessories require separate processing of the track, connectors, and fasteners. Assembly necessitates positioning, fixing, and adjustment, resulting in a long process chain and a tendency to accumulate errors. This invention allows for one-piece molding of the track, eliminating the need for rollers, guide rails, or any other external accessories. This reduces the number of parts compared to accessory-assisted systems, significantly lowering material costs. Furthermore, the backplate and top cover directly interlock via track grooves, simplifying the assembly process to a three-step "alignment-sliding-locking" process, improving efficiency compared to the multi-part assembly of accessory-assisted systems. This invention eliminates accessory processing and assembly steps through structural integration, achieving a simultaneous reduction in both material and process costs.
[0019] Therefore, the display device provided by the present invention can significantly improve the cost and process efficiency.
[0020] 3. In existing technologies, the display device only serves a display function, and the salt inlet requires a separate cover, resulting in redundant components. This invention utilizes a sinking displacement design, allowing the display device to naturally seal the salt inlet when in the closed position, ensuring the cleanliness and hygiene of the water softener's interior. Simultaneously, it presents a seamless, flat appearance, unifying aesthetic value with functional practicality. The display device of this invention can completely cover the salt inlet via sliding displacement, functioning as a salt inlet cover and achieving "two uses in one device." This invention integrates the previously separate display device and salt inlet cover functions, reducing the number of separate salt inlet cover components and further lowering costs and space requirements.
[0021] 4. Existing roller tracks suffer from poor reliability due to concentrated contact stress, which easily leads to jamming after prolonged use caused by wear or deformation. The track system of this invention employs surface contact sliding, combined with baffle openings for smooth sliding. Concave points and convex points provide precise positioning, allowing users to easily open and close the display device with one hand, resulting in high operational comfort. Compared to auxiliary point contact roller structures, the surface contact of this invention distributes the load, making it less prone to wear and deformation over long-term use and avoiding the risk of jamming. This invention achieves both operational convenience and mechanical reliability through structural rigidity design and limiting mechanisms.
[0022] 5. Existing fixed or embedded devices are typically customized for specific display panels, resulting in poor versatility. This invention features multi-specification stepped columns and clips within the back panel, adaptable to display panels of different sizes, achieving interchangeability of display modules. Through standardized interface design, this invention enables a single structure to be compatible with multiple display solutions, enhancing the product's market adaptability and lifecycle value.

[0052] Align the openings 1-5 to 1-8 of the back panel baffle of the display device with the ends of the upper cover tracks 7-4 and 7-5. Tracks 7-4 and 7-5 slide into the "U"-shaped tracks 1-30 and 1-31. Push the display device towards the salt inlet 7-2 until the outer cover 1-13 contacts the edge of the salt inlet, completely covering the salt inlet and entering the closed state. (Refer to...) Figure 11 As shown, this is to prevent foreign objects from entering.
[0053] When salt needs to be added, push the display device in the reverse direction. When the concave dots 1-9 and 1-10 slide past the protruding dots 7-8 and 7-9, a spring-loaded click will indicate that the salt filling port is fully exposed. (See reference) Figure 12 As shown, users can add salt. After adding salt, simply push the display device back in.
[0054] It should be noted that, depending on the differences in product structure and dimensions, track grooves 1-1 and 1-2 can be set as a single or three grooves, and the number of baffle openings can be adjusted accordingly; concave points 1-9 and 1-10 can be designed as conical or square; the number of stepped columns can be increased or decreased to 4 or 8 to accommodate display panels of different sizes. All modifications do not deviate from the core concept of this invention: recessed concealment, one-piece molding, and multiple sliding functions.
[0055] Unless otherwise defined, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. It will also be understood that, unless explicitly defined herein, terms such as those defined in a general dictionary shall be interpreted as having the meaning consistent with their meaning in the relevant field context, and not as having an idealized or overly formal meaning.
[0056] The present invention has been described in detail above through specific embodiments and examples, but these are not intended to limit the invention. Many modifications and improvements can be made by those skilled in the art without departing from the principles of the invention, and these should also be considered within the scope of protection of the present invention.
