Description

Technical Field

[0001] This invention relates to the field of toilet testing technology, specifically a functionally integrated toilet flushing function testing machine. Background Technology

[0002] Toilet flushing function testing is a crucial step in the testing of sanitary ceramic products, involving multiple performance indicators such as flushing volume, subsequent water measurement, and solid matter permeability. Currently, the equipment used for toilet testing in the industry typically consists of independently installed or separate units for the standard test tank, water supply mechanism, test platform, media collection device, and control system. During testing, operators need to arrange the tank position, adjust the water supply pipeline, place the collection container, and switch between different workstations, resulting in a relatively dispersed overall equipment layout and a significant footprint in the laboratory.

[0003] In addition, the position matching between functional modules in existing equipment relies heavily on manual alignment. When testing toilets of different specifications, operators need to repeatedly move and calibrate the position of each component, resulting in a long preparation time before testing and insufficient coordination between different test items. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a functionally integrated toilet flushing function testing machine that enables centralized control and rapid switching of the testing process.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] An integrated toilet flushing function testing machine includes a frame, an adjustable standard test water tank on the front of the frame, a water supply component on the back of the frame, a test platform for installing the toilet to be tested on the front of the frame and below the standard test water tank, a test tank component on the lower part of the test platform, and a control box on the frame.

[0007] The present invention, which adopts the above technical solution, has the following prominent features compared with the prior art:

[0008] The standard test water tank, water supply components, test platform, test tank components, and control box are integrated on the same rack to form a compact test unit, reducing the equipment's footprint. The standard test water tank is adjustable to accommodate water inlets for toilets of different heights, avoiding the cumbersome operation of manually raising the tank or changing tooling. The centralized layout of the water supply components, test platform, test tank components, and control box allows operators to complete test preparation, startup, and data reading at a single workstation, simplifying the testing process.

[0009] As a preferred embodiment, a further technical solution of the present invention is:

[0010] Preferably, the control box includes a boom fixed to the top of the frame, with a mounting box at the end of the boom containing an industrial computer. The boom suspends the control box in front of the frame, providing a wide operating area for easy observation of the testing process. The industrial computer is used to run the test program, collect sensor data, and control the actions of the actuators, thereby achieving centralized control and automated operation of the testing process.

[0011] Preferably, the water supply assembly includes a water storage tank fixed to the bottom of the back side of the frame and a water reservoir fixed to the top of the back side of the frame. A centrifugal pump is connected to the outlet of the water storage tank. A main water inlet pipe is provided between the centrifugal pump and the inlet of the water reservoir. A first outlet pipe opposite to the standard test water tank is connected to the outlet of the water reservoir. A second outlet pipe branches off from the main water inlet pipe. An air-controlled angle seat valve is provided at the branch point of the main water inlet pipe and the second outlet pipe. Two independent water supply paths are formed through the first outlet pipe and the second outlet pipe, which can respectively meet the testing requirements of the two-piece toilet which needs to be supplied with water through the standard water tank and the one-piece toilet which needs to be supplied with water directly. The air-controlled angle seat valve is located at the branch point of the pipe. The water supply path can be switched by opening and closing the valve, and the test mode can be quickly switched without disassembling the pipe.

[0012] Preferably, a pressure gauge and a flow meter are installed on the main inlet pipe between the centrifugal pump and the second outlet pipe. A pressure sensor is installed at the bottom of the water storage tank to detect the water volume in the tank. The pressure gauge and flow meter are used to monitor the water pressure and flow in the main inlet pipe, so that operators can understand the current water supply status. The pressure sensor at the bottom of the water storage tank reflects the water volume in the tank by detecting changes in water pressure, providing a basis for quantitative water supply to the standard test water tank, which helps to improve the accuracy of the test water volume.

[0013] Preferably, the second water outlet pipe has multiple branch pipes, with the outlets of the multiple branch pipes located at different positions and all facing the front of the frame. The outlets of the multiple branch pipes are distributed at different heights or horizontal positions, which can adapt to the inlet positions of toilets of different specifications. During testing, the outlet can be selected according to the actual interface position of the toilet under test, without the need to adjust the pipe or add adapters, making the operation more convenient.

[0014] Preferably, the standard test water tank includes a tank body, a drain solenoid valve inside the tank body, a level probe and a level sensor inside the tank body, and a connecting elbow at the bottom of the tank body for connecting to the toilet's water inlet. The drain solenoid valve is used to control the flushing action, the level probe and level sensor are used to detect changes in the water level in the tank, and the connecting elbow is used to connect to the toilet's water inlet. The above components work together to realize automatic water filling, water level maintenance and timed flushing of the standard water tank, ensuring that the flushing volume of each test meets the preset requirements.

[0015] Preferably, the front sides of the frame are provided with vertical grooves, and two sliders are slidably connected to the outer side of each groove. A crossbeam is fixedly connected between the two opposing sliders. A through threaded hole is opened on the slider along the direction perpendicular to the groove. A locking rod is screwed into the threaded hole. One end of the locking rod is located inside the groove and is provided with a locking head. The other end of the locking rod is provided with a handle. When the handle is turned, the locking head abuts or separates from the inner wall of the groove. A support rod for supporting the water tank body is fixed on the lower crossbeam, and a limiting rod for clamping the two sides of the water tank body is fixed on the upper crossbeam. The height of the crossbeam is adjusted by moving the slider along the groove. The locking rod cooperates with the threaded hole. Turning the handle can make the locking head abut against or separate from the inner wall of the groove, thereby realizing the locking and releasing of the crossbeam position. The support rod of the lower crossbeam provides vertical support for the water tank body, and the limiting rod of the upper crossbeam clamps and positions the two sides of the water tank body, ensuring that the standard test water tank is installed stably and its position is adjustable.

[0016] Preferably, the test bench includes a test frame fixed to the front of the machine frame, with a test platform horizontally slidably connected to the top of the test frame. The sliding direction of the test platform is perpendicular to the machine frame. A drain outlet is provided on the test platform, and a drain pipe is provided below the test platform and at the drain outlet. The test platform can move horizontally in a direction perpendicular to the machine frame to adjust the front and rear position of the toilet under test, so that its water inlet is accurately aligned with the connecting elbow of the standard test water tank, reducing the range of manual handling and adjustment. The drain outlet and drain pipe move synchronously with the test platform to ensure that they are always aligned with the toilet drain outlet, preventing water from overflowing.

[0017] Preferably, the test bucket assembly includes a trolley base slidably connected to the lower part of the test frame. The sliding direction of the trolley base is parallel to the sliding direction of the test platform. A water volume test bucket and a passability test bucket are provided on the trolley base. The trolley base can move horizontally to move different test buckets to the bottom of the drain pipe to collect the medium. The water volume test bucket is used to collect and measure the flushing water volume, and the passability test bucket is used to collect the medium after solid material testing. The two can be quickly switched according to the test items to meet various test requirements.

[0018] Preferably, a metal detection sensor is provided on the outside of the drain pipe to detect whether the medium flowing through the drain pipe contains a metal test object. This sensor can automatically identify the discharge time of the test object in subsequent water tests, provide a trigger signal for data recording, and reduce errors from manual observation.

[0030] The present invention will be further illustrated below with reference to specific embodiments. The purpose of this illustration is solely to provide a better understanding of the invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0031] like Figure 1-10 As shown, this embodiment provides a functionally integrated toilet flushing function testing machine, including a frame 1. The main body is constructed with an aluminum profile frame and covered with a wear-resistant and waterproof POM cover plate to form a semi-enclosed box structure, which protects the internal components and has a neat appearance. The front of the frame 1 is provided with a standard test water tank with adjustable position, and the back of the frame 1 is provided with a water supply component. The front of the frame 1 and below the standard test water tank is provided with a test platform for installing the toilet to be tested. The test tank component is provided under the test platform, and a control box is provided on the frame 1.

[0032] Preferably, the control box includes a boom 2 fixed to the top of the frame 1, and a mounting box 3 is provided at the end of the boom 2. An industrial control computer is installed in the mounting box 3. The boom 2 suspends the control box in front of the frame 1, making the operating area open and convenient for observing the testing process. The industrial control computer is used to run the test program, collect sensor data and control the action of the actuators, so as to realize the centralized control and automated operation of the test process.

[0033] Preferably, the water supply assembly includes a water storage tank 4 fixed to the bottom of the back side of the frame 1 and a water storage tank 5 fixed to the top of the back side of the frame 1. The top of the water storage tank 5 is provided with an overflow pipe communicating with the water storage tank 4. A centrifugal pump 6 is connected to the outlet of the water storage tank 4, providing a stable water pressure with adjustable pressure. A main inlet pipe 7 is provided between the centrifugal pump 6 and the inlet of the water storage tank 5. A first outlet pipe 8, opposite to the standard test water tank, is connected to the outlet of the water storage tank 5. The first outlet pipe 8 extends from the front side of the frame 1. A pneumatically controlled angle seat valve is provided at the outlet of the water storage tank 5. A second outlet pipe 9 branches off from the main inlet pipe 7. A pneumatically controlled angle seat valve is provided at the branch point of the main inlet pipe 7 and the second outlet pipe 9. The water outlet pipe 8 is also equipped with a pneumatically controlled angle seat valve, forming two independent water supply paths through the first water outlet pipe 8 and the second water outlet pipe 9. This can meet the testing requirements of two-piece toilets that need to be supplied with water through a standard water tank and one-piece toilets that need to be supplied with water directly. The pneumatically controlled angle seat valve is located at the branch point of the pipeline. The water supply path can be switched by opening and closing the valve. The test mode can be quickly switched without disassembling the pipeline. When testing a two-piece toilet, the industrial control computer controls the pneumatically controlled angle seat valve to connect the main water inlet pipe 7 to the first water outlet pipe 8, while closing the passage of the second water outlet pipe 9. When testing a one-piece toilet, the industrial control computer controls the pneumatically controlled angle seat valve to connect the main water inlet pipe 7 to the second water outlet pipe 9, while closing the passage of the first water outlet pipe 8.

[0034] Preferably, a pressure gauge 10 and a flow meter 11 are installed on the main inlet pipe 7 between the centrifugal pump 6 and the second outlet pipe 9. A pressure sensor 12 for detecting the water volume in the water storage tank 5 is installed at the bottom of the water storage tank 5. The pressure gauge 10 and the flow meter 11 are used to monitor the water pressure and flow rate in the main inlet pipe 7, so that operators can understand the current water supply status. The pressure sensor 12 at the bottom of the water storage tank 5 reflects the water volume in the tank by detecting changes in water pressure, providing a basis for quantitative water supply to the standard test water tank, which helps to improve the accuracy of the test water volume. The detected pressure signal is transmitted to the industrial control computer in real time. The industrial control computer calculates the actual water volume in the water storage tank 5 according to the preset water level-pressure correspondence. When water needs to be injected into the standard test water tank, after the water volume is set on the industrial control computer and water supply is clicked, the air-controlled angle seat valve on the first water outlet pipe 8 opens to supply water to the standard water tank. At the same time, the pressure sensor 12 detects the water volume discharged from the water storage tank 5. When the water volume reaches the set value, the air-controlled angle seat valve on the first water outlet pipe 8 closes, the centrifugal pump 6 starts, and water is supplied to the water storage tank 5 until the preset upper limit of the water storage tank 5 is reached.

[0035] Preferably, the second water outlet pipe 9 has multiple branch pipes 13. A throttling valve is provided on the main pipe of the second water outlet pipe 9. The outlets of the multiple branch pipes 13 are located at different positions and all face the front of the frame 1. The outlets of the multiple branch pipes 13 are distributed at different heights or horizontal positions, which can adapt to the inlet positions of toilets of different specifications. During testing, the outlet can be selected according to the actual interface position of the toilet under test without adjusting the pipeline or adding adapters, making the operation more convenient. A manual shut-off valve is provided near the outlet end of each branch pipe 13. The manual shut-off valve is located on the back side of the frame 1, and only the interface of the branch pipe 13 is exposed on the front side of the frame 1. It is used to control the opening and closing of the outlet individually. When testing a one-piece toilet, the operator opens the corresponding manual shut-off valve according to the position of the toilet inlet and connects the hose to the toilet inlet; the other unused outlets are kept closed to prevent water leakage.

[0036] Preferably, the standard test water tank includes a tank body 14, a drain solenoid valve 15 inside the tank body 14, a level probe 16 and a level sensor 17 inside the tank body 14, and a connecting elbow 18 at the bottom of the tank body 14 for connecting to the toilet's water inlet. The drain solenoid valve 15 is used to control the flushing action, the level probe 16 and the level sensor 17 are used to detect changes in the water level in the tank, and the connecting elbow 18 is used to connect to the toilet's water inlet. The above components work together to realize automatic water filling, water level maintenance and timed flushing of the standard water tank, ensuring that the flushing volume of each test meets the preset requirements.

[0037] Preferably, the frame 1 has vertical grooves on both sides of its front side. Two sliders 20 are slidably connected to the outer side of each groove. A crossbeam 19 is fixedly connected between the opposing sliders 20. A through threaded hole is formed on each slider 20 perpendicular to the groove. A locking rod 21 is screwed into the threaded hole. One end of the locking rod 21 is located inside the groove and has a locking head. The other end of the locking rod 21 has a handle. When the handle is turned, the locking head abuts against or separates from the inner wall of the groove. A support rod 22 for supporting the water tank body 14 is fixed on the lower crossbeam 19, and a support rod 22 for supporting the water tank is fixed on the upper crossbeam 19. The limiting rods 23 clamping the main body 14 on both sides, and the outer ends of the support rods 22 and the limiting rods 23 are all provided with limiting plates to prevent the water tank body 14 from falling. The height of the crossbeam 19 can be adjusted by moving the slider 20 along the slide groove. The locking rod 21 cooperates with the threaded hole. Turning the handle can make the locking head press against or separate from the inner wall of the slide groove, thereby realizing the locking and releasing of the position of the crossbeam 19. The support rod 22 of the lower crossbeam 19 provides vertical support for the water tank body 14, and the limiting rods 23 of the upper crossbeam 19 clamp and position the water tank body 14 on both sides, ensuring that the standard test water tank is installed stably and its position is adjustable.

[0038] Preferably, the test bench includes a test frame 24 fixed to the front of the frame 1. A test platform 25 is horizontally slidably connected to the top of the test frame 24. The sliding direction of the test platform 25 is perpendicular to the frame 1. A drain outlet 26 is provided on the test platform 25. A drain pipe is provided below the test platform 25 and at the drain outlet 26. The test platform 25 can move horizontally in a direction perpendicular to the frame 1 to adjust the front and rear position of the toilet under test, so that its water inlet is accurately aligned with the connecting elbow 18 of the standard test water tank, reducing the range of manual handling and adjustment. The drain outlet 26 and the drain pipe are connected with the test platform 25. The test platform 25 moves synchronously to ensure it is always aligned with the toilet drain outlet, preventing water overflow. Rollers are installed at the bottom of the test platform 25, and a guide rail is provided at the top of the test frame 24 to cooperate with the rollers. The rollers roll along the guide rail to achieve smooth movement of the test platform 25. Limiting blocks are provided in the direction of movement of the test platform 25 to limit its range of movement and assist in positioning. Experiments show that because the weight of the test platform 25 and the toilet is relatively large compared to the flushing force, and the flushing force is generally downward with a very small lateral component, the test platform 25 will not shift during the test.

[0039] Preferably, the test tank assembly includes a trolley base 27 slidably connected to the lower part of the test frame 24. The sliding direction of the trolley base 27 is parallel to the sliding direction of the test platform 25. A water volume test tank 28 and a passability test tank 29 are provided on the trolley base 27. The trolley base 27 can move horizontally to move different test tanks to the drain pipe to collect the medium. The water volume test tank 28 is used to collect and measure the flushing water volume, and the passability test tank 29 is used to collect the medium after solid material testing. The two can be quickly switched according to the test items to meet various test requirements. The bottom of the trolley base 27 is provided with pulleys that cooperate with the trolley track at the lower part of the test frame 24. The trolley track consists of two parallel stainless steel round bars. The pulleys roll along the round bars to move the trolley base 27. The water volume test tank 28 is a transparent tank with a drain outlet. Its side wall is provided with a hydrostatic level gauge for accurate reading of the water volume. The passability test tank 29 is provided with a screen for separating solid material and water. When conducting the water volume test, the water volume test bucket 28 is moved below the drain pipe; when conducting the passability test, the passability test bucket 29 is moved. Through experiments, it was found that because the weight of the trolley base 27, the water volume test bucket 28 and the passability test bucket 29 is relatively large compared to the flushing force, and the flushing force is downward, the test platform 25 will not be displaced during the test.

[0040] Preferably, a metal detection sensor 30 is provided on the outside of the drain pipe to detect whether the medium flowing through the drain pipe contains a metal test object. It can automatically identify the discharge time of the test object in subsequent water tests, provide a trigger signal for data recording, and reduce the error of manual observation. The metal detection sensor 30 is a ring inductive sensor, which is sleeved on the outside of the drain pipe. When a test object containing metal passes through the drain pipe, the sensor outputs a signal to the industrial control computer, which records the moment and marks it as the discharge time of the test object.

[0041] The industrial control computer is also electrically connected to the centrifugal pump 6, the drain solenoid valve 15, the pressure sensor 12, the flow meter 11, the level sensor 17, the level probe 16, the metal detection sensor 30, etc., to receive detection signals and output control commands.

[0042] During operation, the operator first selects the test mode according to the type of toilet to be tested. If it is a one-piece toilet, water needs to be supplied directly; if it is a two-piece toilet, water needs to be supplied through a standard test tank. The height of the standard test tank is adjusted according to the specifications of the toilet to be tested. The handle of the slider 20 on the front slide of the frame 1 is released to separate the locking head from the inner wall of the slide. The crossbeam 19 is pushed along the slide to the required height, and then the handle is locked. This allows the support rod 22 of the lower crossbeam 19 and the limit rod 23 of the upper crossbeam 19 to stably support and clamp the tank body 14. Then, the toilet to be tested is placed on the test platform 25 of the test bench, and the machine is pushed... The test platform 25 is moved horizontally along the guide rail at the top of the test frame 24 until the toilet inlet is aligned with the connecting bend 18 at the bottom of the standard test tank and connected via a hose. Simultaneously, the toilet drain outlet is aligned with the drain pipe on the test platform 25. Then, the piping is switched according to the test type. For a two-piece toilet test, the industrial control computer controls the pneumatic angle seat valve at the branch point of the main inlet pipe 7 and the first outlet pipe 8 to switch to the first outlet pipe 8 path, connecting the water supply component to the standard test tank. For a one-piece toilet test, the pneumatic angle seat valve is switched to the second outlet pipe 9 path, and the position of the toilet inlet is adjusted accordingly. Open the manual shut-off valve on the corresponding branch pipe 13 on the second water outlet pipe 9, and connect the hose to the toilet inlet; then, according to the test items, move the trolley base 27 along the trolley track so that the water volume test bucket 28 or the passability test bucket 29 is moved directly below the drain pipe; after starting the test program, if it is a two-piece toilet test, the industrial control computer, based on the water volume signal detected by the pressure sensor 12 at the bottom of the water tank 5 or the cumulative flow signal of the flow meter 11, starts the centrifugal pump 6 to replenish water to the water tank 5 through the main water inlet pipe 7 to the set water volume, and then controls the drain solenoid valve 15 in the standard test water tank to open for flushing, and the water in the tank flows through the connecting bend pipe 1 8. The medium discharged from the toilet flows into the test tank below through the drain pipe. If a subsequent water test is to be conducted, the metal detection sensor 30 on the outside of the drain pipe monitors in real time whether the medium contains metal test objects. When a metal object is detected passing through, a signal is output to the industrial control computer to record the discharge time. If it is a one-piece toilet test, the industrial control computer controls the pneumatic angle seat valve to switch to the second water outlet pipe 9 and starts the centrifugal pump 6. Water is directly supplied to the toilet's own water tank through the branch pipe 13 of the second water outlet pipe 9. The water inlet is controlled by the toilet's own water tank accessories. The operator manually touches the flush button to conduct the test. The discharged medium also flows into the test tank below through the drain pipe.
