Description

Technical Field

[0001] This utility model relates to the field of toilet technology, specifically to an electronic toilet device. Background Technology

[0002] Electronic toilets sold in the European market are equipped with a dual-supply system. This system is functionally divided: one supply line connects to the wall-mounted tank, dedicated to cleaning the ceramic body of the toilet bowl; the other supply line directly to the internal cleaning device, serving localized hygiene needs. All components must strictly comply with the EN1717 European standard and incorporate overflow protection mechanisms that meet regulatory requirements.

[0003] To meet the requirements of EN1717 standards, current electronic toilets on the market feature a separate water tank within the bidet unit, specifically designed to supply water for localized body washing. As product design trends lean towards thinner, more streamlined designs, manufacturers have adapted the overflow structure to optimize aesthetics and space. This involves placing the overflow outlet on the side wall of the bidet unit, ensuring it is below the top level of the toilet's ceramic body. However, this design carries a potential safety hazard: if the water level detection element built into the tank malfunctions, it may fail to effectively limit the water level from rising to the safe limit, triggering the overflow mechanism and causing water to drain directly onto the bathroom floor. In extreme cases, this could lead to extensive water accumulation and unnecessary financial losses.

[0004] Therefore, the key challenge facing the industry is to develop and implement a solution that balances innovative design and practicality, ensuring that electronic toilets meet modern aesthetic and space-saving requirements while strictly adhering to safety standards such as EN1717 to guarantee that users can fully enjoy the safety and reliability of the product during use.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] The electronic toilet integrates multiple advanced technologies and user-friendly designs, forming an efficient, convenient, and safe bathroom solution. The device includes a mounting bracket 1, a water tank 2, the toilet body 3, and a sanitary cleaning device 4. The mounting bracket 1, serving as the stable foundation of the entire system, is made of durable materials and its scientifically designed structure ensures the device can be firmly fixed to a wall or other supporting structure, while adapting to installation requirements and pipeline layouts in different environments. The water tank 2's internal housing 21 is equipped with water supply and drainage mechanisms. The front of the housing has an opening 23 for easy maintenance, where the inlet valve 22 can include an inlet valve body, float, and other components. It automatically controls water supply and the water level in the tank according to preset thresholds. Correspondingly, the housing has an inlet connector 24 connected to the water source. The drain valve (not shown) opens rapidly when flushing is triggered and closes automatically after cleaning to prevent leakage. In addition, to protect the water pipes and wires inside the sanitary cleaning device 4 from damage, a guide pipe 25 is installed next to the box. The guide pipe 25 extends vertically and connects to the box 21 at the top.

[0027] The water supply pipe 5 connects the water tank 2 and the toilet body 3. Its structure includes a vertical extension and a horizontal bend, designed to reduce water pressure loss and adapt to different spatial layout requirements. The toilet body 3 is generally made of high-quality ceramic material, possessing excellent stain resistance and easy cleaning. Through a tight connection with the water supply pipe 5, it receives water from the water tank for efficient regular flushing. The toilet body 3 is equipped with a drain pipe 6 at its drain outlet, allowing waste to be quickly discharged after flushing.

[0028] The hygiene cleaning device 4 is an important component embodying the intelligent and comfortable features of the electronic toilet. This device is carefully installed on the rear upper surface of the toilet body 3, and consists of a housing 41 and a cover assembly 42. The housing 41 integrates a series of functional components, such as a heating element 43 that heats the cleaning water to a suitable temperature for human use, ensuring user comfort during use; and a nozzle assembly 44 that utilizes advanced nozzle technology, allowing for flexible adjustment of the spray angle, intensity, and mode to achieve precise, gentle, and effective cleaning of specific areas of the body.

[0029] This application eliminates the need for a dedicated water tank inside the original sanitary cleaning device. Instead, a small water tank 8 is installed inside the water storage tank 21. A water pump 45 draws water from the small water tank 8 via a connecting pipe 7, which then flows into the heating element 43 and is sprayed out by the nozzle assembly 44 to the affected area of ​​the body for cleaning. In other words, the water used by the sanitary cleaning device comes from the small water tank inside the water storage tank 2. This avoids the safety hazards mentioned in the background art.

[0030] In the specific design, the small water tank 8 has an opening at the top, which limits the overflow level of the small water tank. The overflow level of the small water tank 8 is higher than the overflow level of the storage tank 2, so that when the small water tank 8 overflows, the overflow water will be discharged into the storage tank 2. This means that when the water level in the small water tank 8 rises to the top, the excess water will flow over its top into the storage tank 2, thereby avoiding the risk of overflow.

[0031] To control the water level inside the small water tank 8, the small water tank 8 is equipped with a water inlet control mechanism 81, which automatically adjusts the water level inside the small water tank 8 according to a preset threshold. The water inlet control mechanism can operate mechanically or electronically. In a mechanical water inlet control mechanism, components such as floats or buoys are typically used to sense changes in the water level. For example, the float or buoy rises with the water level, and when it reaches the preset maximum water level, it cuts off the water supply through a lever or valve mechanism, preventing further water flow into the small water tank 8; conversely, when the water level drops, the float or buoy sinks, reopening the water supply and allowing the small water tank 8 to refill. Figure 5 The diagram shows a traditional float-type water inlet control mechanism, whose structural principle is basically the same as that of the water inlet valve 22 used in the water storage tank 2.

[0032] For electronic control methods, the water inlet control mechanism monitors the water level through electronic sensors or precisely controls the replenishment and shutdown of the small water tank based on the actual needs of the sanitation cleaning device and pre-programmed instructions. For example... Figure 6 The electronic water inlet control mechanism is shown. Its outlet is located above the small water tank 8 and is isolated from the top of the small water tank 8 by a certain distance. This ensures that even if the electronic control component fails, the water in the small water tank 8 will not flow back into the water supply system, thus complying with the EN1717 standard for preventing sewage backflow.

[0033] Meanwhile, to supply water to the small water tank, the inlet connector 24 is connected to a water distribution component 26 with dual outlets, enabling dedicated water supply to the small water tank. Specifically, the water distribution component 26 is designed with two independent outlets. One outlet 261 is directly connected to the inlet valve 22, and this water flows into the tank 21 for the flushing function of the toilet body 3; while the other outlet 262 is designed to connect to a dedicated water inlet control mechanism for the small water tank 8, allowing a portion of the water to be directed into the small water tank to meet the water needs of the sanitary cleaning device.

[0034] As for the method of obtaining water, there are many ways. For example... Figure 1-2 The connecting pipe 7 is connected at one end to the water inlet connector 411 of the sanitary cleaning device 4, and at the other end extends from the bottom up through the guide pipe 25 into the water storage tank 2. The connecting pipe 7 also has a water intake section 71, which enters the water storage area of ​​the small water tank 8 from top to bottom to draw water. To ensure that the water intake section 71 maintains a stable and accurate position inside the small water tank 8, a snap-fit ​​mechanism (not shown) is provided inside the water storage tank. This can be a special fixing device pre-designed and manufactured within the water storage tank wall, typically manifested as a ring-shaped snap or groove structure. When the water intake section is installed, its outer circumference precisely matches and locks with the snap or groove inside the water storage tank, forming a secure mechanical connection. This ensures that the water intake section will not shift or loosen due to water pressure changes or physical impacts during use, thereby guaranteeing the stability and reliability of the water supply. Preferably, the water intake section is integrally formed with the connecting pipe 7, meaning it is part of the connecting pipe 7. Figure 4 As shown, a water guide path 82 can also be provided inside the small water tank 8, connecting to the bottom of the small water tank 8, and the water intake section 71 is connected to the interface at the top of the water guide path 82.

[0035] Another, relatively simple, method of water intake involves setting an outlet in the water storage area of ​​the small water tank 8, which is then connected to the connecting pipe 7. Preferably, this outlet is located at the bottom of the small water tank 8. In this way, the water pump 45 can draw water from the small water tank 8 through this outlet.

[0036] Regarding the fixing of the small water tank 8, as follows: Figure 4 As shown, the following methods can be used: the inlet valve 22 and the drain valve inside the water tank are generally fixed in the internal space of the water tank by a dedicated fixing bracket 27. Here, the small water tank 8 can be directly connected to the fixing bracket 27, which can be done using a one-piece molding process, meaning that during manufacturing, the small water tank 8 and the fixing bracket 27 are directly manufactured as a single unit, which helps to enhance the overall structural integrity. Alternatively, a separate connection method can be adopted, that is, the small water tank and the fixing bracket are manufactured separately, and then assembled by bolts, welding, or other connection methods. This method is relatively flexible and facilitates disassembly and assembly.

[0037] To purify the water used for localized body washing, a filter can be installed at the inlet of the connecting pipe fitting 7 to pre-treat the water source. This filter effectively removes impurities, particulate matter, and other contaminants from the water. To optimize the filtration effect and water flow path, it is preferable to maintain the distance between the inlet of the connecting pipe fitting and the bottom surface of the water storage tank between 1cm and 10cm. This distance ensures sufficient water volume while preventing the possibility of sediment from the bottom of the small water tank being sucked into the connecting pipe fitting.

[0038] Furthermore, a sterilization component 46 is installed in the flow path where the water pump draws water and delivers it to the nozzle assembly. This means that the water drawn from the small water tank is sterilized before entering the water pump, effectively killing potential bacteria, viruses, and other harmful microorganisms, thus providing healthier and safer cleaning water. In addition, the hygienic cleaning device also includes an intelligent water circuit switch 47, which is linked to the working status of the water pump 45. When the water pump starts, the water circuit switch 47 automatically connects the internal water circuit, allowing the sterilized water to flow smoothly into the water pump 45 and further supply the nozzle assembly 44; when the water pump 45 is turned off, the water circuit switch 47 cuts off the water circuit.

It should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the above teachings or the technology or knowledge in related fields. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be protected within the scope of the appended claims.
