Description

Technical Field

[0001] The present invention relates to the technical field of toilets, and in particular to an electronic toilet device. Background Art

[0002] Electronic toilets sold in Europe are equipped with a dual water supply system. This system is divided by function: one water source is connected to a wall-mounted cistern for cleaning the toilet's ceramic body; the other water source is directly supplied to the internal sanitary cleaning device for personal hygiene. The corresponding components must strictly comply with the European standard EN1717, and the design must include overflow protection mechanisms that meet regulatory requirements.

[0003] To meet the requirements of the EN1717 standard, electronic toilets currently on the market are equipped with an independent water tank within the sanitary cleaning device, which is specifically responsible for supplying water for local body washing. As product design trends towards thinner and more streamlined designs, manufacturers, while pursuing aesthetics and space optimization, have adapted the overflow structure, placing the overflow port on the side wall of the sanitary cleaning device and ensuring it is below the top level of the toilet's ceramic body. However, this design comes with potential safety hazards: if the liquid level detection element built into the water tank fails, it may not be able to effectively limit the water level in the water tank from rising to the safe upper limit, thereby triggering the overflow mechanism and causing the water to be discharged directly onto the bathroom floor through the overflow port. In extreme cases, it may even cause large-scale water accumulation, resulting in unnecessary economic 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 can meet modern aesthetic and space-saving requirements, while also strictly adhering to safety standards such as EN1717 to ensure that users can fully enjoy the safety and reliability of the product during use.

DETAILED DESCRIPTION

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] The electronic toilet system integrates multiple advanced technologies and user-friendly designs to create an efficient, convenient, and safe bathroom solution. The system comprises a mounting frame 1, a water tank 2, a toilet body 3, and a sanitary cleaning device 4. The mounting frame 1, serving as the system's foundation, is constructed from durable materials and features a scientifically designed design to ensure secure attachment to a wall or other supporting structure, adapting to installation requirements and pipeline layouts in diverse environments. The water tank 2 houses the water supply and drainage mechanisms within its housing 21. An opening 23 is located at the front of the housing for easy access by maintenance personnel. The water inlet valve 22, which includes components such as a valve body and a float, automatically controls water supply and the water level within the tank based on preset thresholds. A corresponding water inlet connector 24 is provided within the housing to connect to the water source. The drain valve (not shown) opens rapidly when the flush is triggered and automatically closes upon completion of the flush, preventing leakage. In addition, in order to protect the water pipes and wires in the sanitary cleaning device 4 from damage, a guide pipe 25 is provided next to the box body. The guide pipe 25 extends in a vertical direction and is connected to the box body 21 at the upper part.

[0022] The water supply pipe 5 connects the water tank 2 to the toilet body 3. Its structure consists of a vertical extension and a horizontal curve, designed to minimize water pressure loss and accommodate various spatial layout requirements. The toilet body 3 is typically constructed of high-quality ceramic, offering excellent stain resistance and easy cleanability. By tightly connecting to the water supply pipe 5, it receives water from the water tank for efficient regular flushing. A drain pipe 6 is located at the waste outlet of the toilet body 3, ensuring rapid drainage of cleaned waste.

[0023] The sanitary cleaning device 4 is a crucial component of the electronic toilet's intelligent and comfortable features. Carefully installed on the upper rear surface of the toilet body 3, it consists of a housing 41 and a cover assembly 42. Housing 41 houses a series of functional components, such as a heating assembly 43 that heats the cleaning water to a suitable temperature for human consumption, ensuring user comfort. The nozzle assembly 44 utilizes advanced nozzle technology, allowing for flexible adjustment of spray angle, force, and pattern, ensuring precise, gentle, and effective cleaning of the body.

[0024] This solution eliminates the traditional dedicated water tank within the sanitary cleaning device. Instead, a small water tank 8 is installed within the water storage tank body 21. A water pump 45 pumps water from the small water tank 8 through a connecting pipe 7, which then enters the heating assembly 43 and is then sprayed by the nozzle assembly 44 onto the human body for cleaning. In other words, the water used in the sanitary cleaning device comes from the small water tank within the water storage tank 2. This avoids the safety hazards mentioned in the background art.

[0025] In the specific solution, the top of the small water tank 8 is open and the overflow level of the small water tank is defined by the top. The overflow level of the small water tank 8 is higher than the overflow level of the water storage tank 2, so that when the small water tank 8 overflows, the overflow water will be discharged into the water 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 water storage tank 2, thereby avoiding the risk of overflow.

[0026] In order to control the amount of water inside the small water tank 8, the small water tank 8 is provided with a water inlet control mechanism 81, which can automatically adjust the water level in the small water tank 8 according to a preset threshold value. The working mode of the water inlet control mechanism can be either mechanical or electronic. In the mechanical water inlet control mechanism, components such as floats and floats are usually used to sense changes in water levels. For example, the float or float rises as the water level rises. When the preset maximum water level is reached, the water source is cut off through a lever or valve mechanism to prevent water from continuing to flow into the small water tank 8; conversely, when the water level drops, the float or float sinks, reopening the water source so that the small water tank 8 can be filled with water again. Figure 5 The figure shows a traditional float type water inlet control mechanism, the structural principle of which is basically the same as the water inlet valve 22 used in the water tank 2.

[0027] For electronic control, the water inlet control mechanism monitors the water level through electronic sensors according to the actual needs of the sanitary cleaning device, or accurately controls the water filling and water cut-off process of the small water tank according to pre-programmed instructions. Figure 6 The figure shows an electronic water inlet control mechanism, the water outlet of which is arranged above the small water tank 8 and separated from the top of the small water tank 8 by a distance, so as to ensure 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, thereby complying with the provisions of the EN1717 standard on preventing sewage backflow.

[0028] To supply water to the small water tank, the water inlet connector 24 connects to a dual-outlet water distribution member 26, providing dedicated water supply to the small water tank. Specifically, the water distribution member 26 is designed with two independent outlets. One outlet 261 is directly connected to the water inlet valve 22, and this portion of water flows into the tank 21 for flushing the toilet seat 3. The other outlet 262 is designed to connect to a water inlet control mechanism specifically for the small water tank 8, allowing a portion of the water source to be directed into the small water tank to meet the water needs of the sanitary cleaning device.

[0029] As for the way to get water, there are many ways. Figure 1-2 As described, one end of the connecting pipe 7 is connected to the water inlet joint 411 of the sanitary cleaning device 4, and the other end extends from the water tank 2 from bottom to top through the inside of the guide pipe 25. 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 take water. In order 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 in the water tank, which can be a special fixing device pre-designed and manufactured in the wall of the water tank, usually in the form of an annular snap or groove structure. When the water intake section is installed, its outer contour will precisely match and lock with the snap or groove in the water tank to form a firm mechanical connection. In this way, it can be ensured that the water intake section will not shift or loosen due to changes in water pressure or physical impact during use, thereby ensuring the stability and reliability of the water supply. The water intake section is preferably formed integrally with the connecting pipe 7, and it can be understood that the water intake section is part of the connecting pipe 7. As Figure 4 As shown, a water conduit 82 connected to the bottom of the small water tank 8 can also be provided in the small water tank 8 , and the water intake section 71 is connected to the interface at the top of the water conduit 82 .

[0030] Another way to take water is relatively simple, and a water outlet can be set in the water storage area of ​​the small water tank 8, and the water outlet is connected to the connecting pipe 7. The water outlet is preferably set at the bottom of the small water tank 8. In this way, the water pump 45 can extract the water in the small water tank 8 through the water outlet.

[0031] Regarding the fixing of the small water tank 8, Figure 4As shown, the following method can be used: the water inlet valve 22 and the drain valve in the water storage tank are generally fixed to the internal space of the water tank via a dedicated fixing bracket 27. Here, the small water tank 8 can be directly connected to the fixing bracket 27, which can be achieved through an integrated molding process. That is, during the manufacturing process, the small water tank 8 and the fixing bracket 27 are directly manufactured as a single unit, which helps to enhance the integrity of the structure. Alternatively, a separate connection method can be adopted, that is, the small water tank and the fixing bracket are manufactured separately and then assembled together using bolts, welding, or other connection methods. This method is relatively flexible and easy to disassemble and assemble.

[0032] To purify the water used for local body washing, a filter can be installed at the water inlet of the connecting pipe 7 to pre-treat the water source. This filter effectively removes impurities, particulate matter, and other contaminants from the water. To optimize the filtering effect and water flow path, the distance between the water inlet of the connecting pipe and the bottom of the water storage tank is preferably maintained between 1 cm and 10 cm. This distance ensures sufficient water flow while preventing sediment from the bottom of the small water tank from being drawn into the connecting pipe.

[0033] Furthermore, a sterilization component 46 is installed in the flow path where the water pump draws in 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 harmful microorganisms such as bacteria and viruses, thereby providing healthier and safer cleaning water. In addition, the sanitary cleaning device also includes an intelligently controlled water circuit switch 47, which is linked to the operating status of the water pump 45. When the water pump is started, 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 shuts off the water circuit.

Rather, the present invention can be used in various other combinations, modifications, and environments, and can be modified within the scope of the present invention through the teachings above or through techniques or knowledge in the relevant art. Modifications and variations made by those skilled in the art without departing from the spirit and scope of the present invention are intended to be within the scope of the appended claims.
