Description

Technical Field

[0001] This invention relates to the field of sanitary ware technology, and in particular to a folding self-cleaning toilet. Background Technology

[0002] Most existing smart toilets are floor-standing or wall-mounted, with the toilet body fixed horizontally. This structure has the problems of large footprint and low utilization of the bathroom. Moreover, whether used in a home or a public place, it requires regular manual cleaning, which increases the labor burden and labor costs.

[0003] Currently known methods for cleaning toilets are all manual cleaning; existing patent literature does not contain any solutions for automatic cleaning. Although there are some records of folding toilets, they are all unrelated to cleaning. For example, Chinese patent application publication number CN108894297A discloses a folding toilet, including a toilet bowl; the toilet bowl includes a toilet bowl body adapted to rotate between horizontal and vertical directions, a toilet bowl edge adapted for a user to sit on, and a water storage mechanism; the toilet bowl body includes a toilet bowl cavity, an opening on the toilet bowl cavity, and a water outlet and a sewage outlet inside the toilet bowl cavity; the toilet bowl edge is provided along the opening, and the water outlet is adapted to connect to an external water supply device; the water storage mechanism includes a blocking member, which is provided at the opening position where the toilet bowl edge is not provided, and completely or partially blocks the opening position where the toilet bowl edge is not provided; when the toilet bowl body rotates and rotates from the horizontal direction to the vertical direction, the toilet bowl body and the blocking member form a water storage cavity suitable for storing sewage. The solution converts the toilet into a horizontal and vertical unit so that it can be stored vertically when not in use, reducing the floor space occupied by the existing toilet. However, the solution only includes a flushing device and does not include a cleaning device, so manual cleaning is still required at regular intervals.

[0004] For example, Chinese patent application CN110219353A discloses a folding household toilet, consisting of a frame and a toilet seat. The toilet seat is connected to the frame via a pivot. After use, the toilet seat can be folded upwards and stored in a pre-reserved slot in the frame. The upper part of the frame has a built-in water tank, a flush button, and a seat release button. The toilet seat has a seat on top with latches. When the toilet seat is folded, it is secured by latches into the slots above the frame. During use, the toilet seat is released by lightly pressing the flush button and the seat release button. This design also reduces space usage through folding, but it only includes the traditional flushing function and cannot effectively clean the toilet.

[0005] It is evident that the aforementioned patent documents all address the issue of toilet floor space. However, for toilets, especially those in public places, to ensure cleanliness and prevent the spread of disease, it is best to clean them before and after each use. Obviously, existing toilets cannot meet this requirement based on manual cleaning. Therefore, how to improve the self-cleaning ability of toilets is a technical problem that those skilled in the art need to solve. Summary of the Invention

Detailed Implementation

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] The purpose of this invention is to provide a folding self-cleaning toilet to solve the problems existing in the prior art. The toilet body is connected to the cabinet through a rotating drive component. When in use, the toilet body can be unfolded into a horizontal state, and after use, it can be folded into the cabinet into a vertical state. The toilet body is cleaned by a spray nozzle component inside the cabinet, which can achieve self-cleaning of the toilet body, improve the cleaning ability of the toilet body, and reduce labor costs.

[0041] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] like Figures 1-12As shown, the present invention provides a folding self-cleaning toilet, including a cabinet 1 and a toilet body 2. The toilet body 2 is connected to the cabinet 1 and can be rotated into or out of the cabinet 1. The toilet body 2 includes a bowl portion 21 and a rotating support portion 22 connected to the bowl portion 21. The bowl portion 21 can be in the shape of a conventional toilet, having a seat ring 211 that contacts the buttocks. The rotating support portion 22 is connected to the cabinet 1 via a rotating drive assembly 4, and is used to support the bowl portion 21 and drive the bowl portion 21 to switch between a horizontal and a vertical state, so that the bowl portion 21 can be horizontally located outside the cabinet 1 and vertically located inside the cabinet 1. The cabinet 1 includes a frame 11 and a shell or panel surrounding the frame 11. The front of the cabinet 1 has a doorway through which the toilet bowl 21 can rotate. A curtain assembly 6 is provided at the doorway for closing it. The doorway can be closed after the toilet bowl 21 rotates out of the cabinet 1, and similarly, after the toilet bowl 21 rotates into the cabinet 1. The cabinet 1, with the doorway closed, forms a closed space for cleaning the toilet bowl 21. This closed space includes a cleaning area at the top and a waste disposal area at the bottom. The cleaning area is equipped with a nozzle assembly 3, which includes several nozzles that spray water towards the toilet bowl 21. The nozzles are connected to a water supply device 5 via pipes, and the water jets from the nozzles impact and flush the toilet bowl 21. The sewage discharge area is equipped with a first sewage outlet and a second sewage outlet. The first sewage outlet is used to discharge wastewater generated from flushing the toilet bowl 21 inside the cabinet 1. The second sewage outlet is connected to the toilet bowl 21 via a sewage hose 271 and is used to discharge waste containing feces generated inside the toilet bowl 21. The first and second sewage outlets can be connected or are independent outlets. In summary, this invention connects the toilet body 2 to the cabinet 1 via a rotation drive assembly 4. The toilet body 2 can be unfolded into a horizontal state during use and folded into a vertical state inside the cabinet 1 after use. The toilet body 2 is cleaned inside the cabinet 1 using a spray nozzle assembly 3, achieving self-cleaning of the toilet body 2, improving its cleaning ability, and reducing the labor costs associated with cleaning the toilet body 2. Since manual cleaning is not required, self-cleaning can be performed after each use, effectively reducing the spread of diseases.

[0043] like Figures 3-4 and Figure 6As shown, the nozzle assembly 3 includes a first nozzle 31 symmetrically arranged at the top of the cabinet 1, a second nozzle 32 symmetrically arranged at the back of the cabinet 1, and a third nozzle 33 and a fourth nozzle 34 of different lengths arranged vertically in the middle of the cabinet 1. Each nozzle can be connected via different branches, which converge to the same main cleaning pipe 57. The nozzles can be rotary, increasing coverage and effectively cleaning all parts of the toilet body 2 using jet spray. Specifically, the first nozzle 31 faces the outside of the toilet body 2, the second nozzle 32 faces the seat 211 of the toilet body 2, and the third and fourth nozzles 33 and 34 face the inside of the toilet body 2 (i.e., the bowl 21), thus achieving comprehensive cleaning of the toilet body 2 and ensuring effective cleaning. An ultraviolet lamp 9 can also be installed inside the cabinet 1 to sterilize the environment inside. These cleaning and sterilization methods effectively reduce the risk of disease transmission.

[0044] like Figure 3 and Figure 5 As shown, the rotation drive assembly 4 includes an electric cylinder 41, which has a fixed end and a movable end. The extension and retraction of the movable end serves as the power to rotate the rotation support 22. Specifically, the fixed end is connected to the cabinet 1 (the frame 11 that makes up the cabinet 1) via a first hinge structure 42, the movable end is connected to the rotation support 22 via a second hinge structure 43, and the rotation support 22 is connected to the cabinet 1 (the frame 11 that makes up the cabinet 1) via a third hinge structure 44. The first hinge structure 42, the second hinge structure 43, and the third hinge structure 44 are arranged in a triangular pattern.

[0045] like Figure 7 As shown, the door curtain assembly 6 includes a mounting base 61 fixed on the cabinet 1 (the frame 11 that makes up the cabinet 1), a winding drum 62 rotatably mounted on the mounting base 61, and a roller blind 63 connected to the winding drum 62. The winding drum 62 is connected to a winding motor that drives its rotation. The winding drum 62 can be rotated forward and backward by the winding motor, which can realize the raising and lowering of the roller blind 63. Tracks 64 with the same width as the roller blind 63 can also be provided on both sides of the doorway. The roller blind 63 is slidably mounted on the tracks 64. The tracks 64 can constrain the raising and lowering path of the roller blind 63, ensuring that it can be raised and lowered in place. In addition, when the toilet body 2 is flushed inside the cabinet 1, the roller blind 63 can effectively block the splashing water. A first limit sensor 65 and a second limit sensor 66 are respectively installed at the top and bottom positions of the roller shutter 63. The position of the roller shutter 63 can be determined based on these sensors, and the signal can be used to trigger the next action. At the same time, the first limit sensor 65 can be used to determine whether the toilet body 2 has turned to a vertical position, and the second limit sensor 66 can be used to determine whether the toilet body 2 has turned to a horizontal position.

[0046] like Figures 3-4 , Figures 8-10 As shown, the water supply device 5 includes a water tank 51, a water pump 52 connected to the water tank 51 for discharging water, and an inlet filter 53 connected to the water tank 51. The inlet filter 53 is connected to an external water source, which filters the water and stores it in the water tank 51 for later use. The water pump 52 is connected to a cleaning pipe 57 via a solenoid valve 54. The cleaning pipe 57 is connected to the nozzle assembly 3. The water pump 52 provides water pressure to the cleaning pipe 57, which in turn provides the spray pressure to the nozzle. The solenoid valve 54 controls the opening and closing of the cleaning pipe 57. The water tank 51 may be equipped with a level sensor and a solenoid valve for automatic timed water replenishment.

[0047] like Figure 2 , Figures 8-11 As shown, the water pump 52 is connected to a water injection pipe 55 via a solenoid valve 54. The water injection pipe 55 leads into the toilet bowl section 21. The toilet bowl section 21 has a drain outlet 27 connected to a sewage discharge hose 271 on the side facing the rotating support section 22. When the toilet bowl section 21 is in a horizontal state, the height of the drain outlet 27 is lower than the height of the middle part of the sewage discharge hose 271. A certain amount of water can be injected into the toilet bowl section 21 through the water injection pipe 55. By injecting a certain amount of water during use, a water seal structure can be formed to prevent odor gas leakage, and feces can be prevented from sticking to the inner wall of the toilet bowl section 21. A siphon effect can also be created to facilitate the flushing of feces.

[0048] like Figure 2 , Figures 8-11 As shown, the water pump 52 is connected to the flushing pipe 56 via the solenoid valve 54. The flushing pipe 56 is connected to the heating module 562 via the outlet filter 561. The heating module 562 is divided into three branches via the water distribution valve 563. Two branches are connected to the posterior wash nozzle and feminine wash nozzle in the flushing head 564, respectively. The third branch is connected to the cleaning head 565, which is used to clean the flushing head 564. The flushing head 564 faces into the toilet bowl section 21 through the flushing port 24. The heating mode of the heating module 562 can be adjusted to output flushing water at different temperatures as needed.

[0049] The water pump 52 is connected to the water injection pipe 55, flushing pipe 56 and cleaning pipe 57 via the solenoid valve 54. In practical applications, the three branch pipes can be equipped with independent solenoid valves 54 to achieve independent control of the three branch pipes. Alternatively, a four-way solenoid valve can be used to control the three output paths on a single four-way solenoid valve.

[0050] like Figures 3-4 , Figure 6As shown, a hot air assembly 8 is installed inside the cabinet 1. This assembly 8 dries the humid environment inside the cabinet 1, reducing bacterial growth. Specifically, the hot air assembly 8 includes a heater 81 located at the top inside the cabinet 1, and an air inlet 82 and an exhaust outlet (not shown in the figure, which can be located on opposite side walls of the cabinet 1) on the cabinet 1. The heater 81 has a downward-facing exhaust outlet, which dries the environment inside the cabinet 1 or the toilet body 2. The air inlet 82 is connected to the heater 81 via a first air intake fan 83, drawing in outside air. The heated air is then exhausted through the exhaust outlet. The heater 81 can be arranged in a U-shape, with multiple exhaust outlets along the length of the bottom of the horizontal and vertical structure, allowing for even airflow into the cabinet 1.

[0051] like Figure 2 and Figure 11 As shown, the hot air assembly 8 may further include a second air intake fan 251. An air inlet 25 and an air outlet 26 are provided on the side of the toilet bowl 21 facing the rotating support 22. The air inlet 25 is connected to the inner cavity of the cabinet 1 via the second air intake fan 251, and the air outlet 26 is connected to the inner cavity of the cabinet 1 via the exhaust fan 261. The second air intake fan 251 can exhaust hot air from the heater 81 into the toilet bowl 21 to dry the buttocks, enhancing user comfort. Therefore, the heater 81 used for drying the cabinet 1 and drying the buttocks can be shared, thus reducing manufacturing costs. The exhaust fan 261 can temporarily store odors from the toilet bowl 21 inside the cabinet 1, reducing the impact of odors on the user.

[0052] like Figures 2-3 , Figures 8-12 As shown, the toilet includes a urine testing component 7, which comprises a urine testing module 71 housed within the cabinet 1 and a collection module housed within the toilet body 2. The urine testing module 71 is a purchased finished product and can test urine after it is added to determine the condition of any disease. A urine inlet 28, connected to the urine testing module 71, is located at the top of the rotating support 22. Urine is added to the urine testing module 71 through the urine inlet 28. The urine testing module 71 is connected to a wastewater hose 271 via a urination tube 72, and the urine after testing is completed is discharged into the wastewater hose 271 through the urination tube 72. The collection module includes a rotary motor 74 installed inside the seat ring 211 and a urine collector 73 connected to the rotary motor 74. The urine collector 73 can rotate out of or into the seat ring 211 by rotating the rotary motor 74, collecting urine after rotating out of the seat ring 211.

[0053] The working process of this invention is as follows:

[0054] When not in use, the toilet body 2 is folded and stored inside the cabinet 1. When needed, it can be opened manually or automatically. For manual opening, pressing the button on the remote control activates the drive assembly 4 and the curtain assembly 6, which receive signals and begin operation. For automatic opening, when a person approaches the distance sensor on the cabinet 1 within 80 cm (the sensing distance can be adjusted according to actual needs), the winding motor on the cabinet 1 starts to retract the curtain 63. Once the curtain 63 is fully retracted, the first limit sensor 65 is triggered. At this time, the electric cylinder 41 inside the cabinet 1 starts working, rotating the toilet body 2 out and placing it in a horizontal position. After reaching the horizontal position, the second limit sensor 66 is triggered, and the curtain 63 falls. At this point, the electric cylinder 41 is de-energized, and the water storage solenoid valve and water pump 52 are simultaneously activated, adding a predetermined amount of water to the toilet bowl 21 through the water injection pipe 55. The amount of water stored is determined by the duration of the water pump 52's operation controlled by the main controller (the duration is adjustable). After the water pump 52 and the water storage solenoid valve are de-energized, the exhaust fan 261 starts, and the toilet can then be used. A heating element 23 is installed inside the seat ring 211 to heat the seat ring 211 and improve comfort. The heating element 23 can be kept on continuously, and the temperature can be manually adjusted for convenient use.

[0055] After using the toilet, the washing function on the remote control can be activated (using the posterior wash nozzle and feminine wash nozzle to achieve posterior wash mode and feminine wash mode respectively), and the drying function can be achieved using the second air intake fan 251. If the urine test function is required, it can be performed using the urine test component 7.

[0056] When a person moves 50 centimeters away from the distance sensor, the winding motor inside cabinet 1 starts and begins to retract the roller shutter 63. Once the roller shutter 63 is fully retracted, the first limit sensor 65 is triggered. At this time, the electric cylinder 41 inside cabinet 1 starts working, rotating and pushing the toilet body 2 into cabinet 1. During the rotation of the toilet body 2, most of the fecal matter will automatically flow to the drain hose 271 and be discharged into the pipe system after the electric cylinder 41 lifts the toilet body 2 beyond a certain angle. The remaining waste can be cleaned by the subsequent spray nozzle assembly 3. After the toilet body 2 is in a vertical position inside cabinet 1, the first limit sensor 65 is triggered. Limit sensor 66 de-energizes electric cylinder 41, and roller shutter 63 descends. Once roller shutter 63 is fully descended, it triggers second limit sensor 66, simultaneously activating solenoid valve 54 and water pump 52 connected to cleaning pipe 57. This initiates high-pressure flushing of the inner and outer sides of toilet body 2 and seat ring 211. The entire flushing system is equipped with six rotating flushing nozzles, allowing for 360-degree flushing of toilet body 2. Flushing wastewater in the bowl 21 flows into the pipe via drain hose 271, while flushing wastewater on the outside of toilet body 2 falls directly to the bottom of cabinet 1 and collects at the drain outlet before being discharged into the pipe system. After high-pressure flushing is completed according to the set time, the system automatically activates hot air drying using hot air assembly 8, and finally, ultraviolet sterilization using ultraviolet lamp 9. Once all tasks are completed within the set time, the toilet enters a dormant state, awaiting the next work cycle.

[0057] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
