Description

Technical Field

[0001] This invention relates to a toilet with a simple flushing device and a toilet flushing method. Background Technology

[0002] Currently, with the improvement of living standards, the flushing functions of toilets are becoming increasingly diversified to meet user needs. In particular, the flushing coordination between the brush ring channel and the main flush channel is crucial. The water inlet mechanism supplies water to the brush ring channel to flush the inner wall of the toilet, and also supplies water to the water tank to supply water to the main flush channel. Therefore, it is necessary to control both the timing of water supply to the brush ring channel and the water inlet to the toilet tank. However, in the existing water inlet mechanism's water-stopping component, there is only one pressure relief hole on its back pressure chamber, which is insufficient to meet the diverse control requirements of the water inlet mechanism. Summary of the Invention

[0003] To solve the above problems, the present invention provides a toilet with a simple flushing device and a toilet flushing method. This solution makes the control of the water inlet mechanism more flexible and diverse by setting two pressure relief holes on the back pressure chamber, which can meet the needs of different functions. The structure is simple and the function is reliable.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A toilet with a simple flushing device includes a brush ring water channel for flushing the inner wall of the toilet bowl and a main flushing water channel connected to the bottom of the toilet bowl, and further includes:

[0006] A water tank having an inner cavity for storing flushing water, the water tank having a drainage channel connecting the inner cavity of the water tank and the main flushing channel;

[0007] The water inlet mechanism includes a water-stopping unit for opening or closing the water inlet mechanism. The water-stopping unit includes a back pressure chamber with a first pressure relief hole and a second pressure relief hole. When both the first pressure relief hole and the second pressure relief hole are closed, the water inlet mechanism is closed. When at least one of the first pressure relief hole and the second pressure relief hole is open, the water inlet mechanism is opened. When the water inlet mechanism is open, the water outlet channel of the water inlet mechanism supplies water to the brush ring water channel or the inner cavity of the water tank.

[0008] A drainage mechanism that can open or close the drainage channel;

[0009] The first starting unit is used to start the drainage mechanism to open the drainage channel; when the first starting unit is started, the drainage mechanism opens the drainage channel.

[0010] Preferably, it also includes a second starting unit, which is used to start the water inlet mechanism to turn on the water inlet. When the second starting unit is turned on, the water outlet channel supplies water to the brush ring water channel for a first preset time to flush the inner wall of the toilet bowl.

[0011] Preferably, when the first starting unit is started, the water inlet mechanism is opened under the action of the first starting unit or under the action of the water level in the water tank.

[0012] Preferably, when the first starting unit is activated, the water inlet mechanism is activated before the drainage mechanism under the action of the first starting unit or the second starting unit, the water outlet channel supplies water to the brush ring water channel, and the drainage mechanism is activated after the water outlet channel supplies water to the brush ring water channel for a second preset time.

[0013] Preferably, the water-stopping unit further includes an electronic control component and a float assembly. The electronic control component opens or closes the first pressure relief hole under the control of the circuit. The float assembly includes a float, which rises or falls with the water level in the water tank cavity to drive the float assembly to open or close the second pressure relief hole.

[0014] Preferably, when the second starting unit is activated, the electronic control component opens the first pressure relief hole, causing the water outlet channel to supply water to the brush ring water channel for the first preset time.

[0015] Preferably, when the first starting unit is activated, the electronic control component opens the first pressure relief hole, allowing the water outlet channel to supply water to the brush ring water channel, and after a second preset time, the drainage mechanism opens the drainage channel.

[0016] Preferably, the drainage mechanism includes a valve core for opening or closing the drainage channel. The float assembly is linked to the valve core or the first starting unit. When the first starting unit is activated, the drainage mechanism opens to drain water while the second pressure relief hole opens to allow water to enter the water inlet mechanism. The electronic control assembly controls the first pressure relief hole to close before the second pressure relief hole closes. The float rises with the water level in the water tank cavity to close the second pressure relief hole, thereby stopping the water inlet mechanism.

[0017] Preferably, when the first starting unit is started, the float opens the second pressure relief hole as the water level in the inner cavity of the water tank falls, so that the water inlet mechanism can start water intake, and the electronic control component controls the first pressure relief hole to close before the second pressure relief hole closes, and the float rises as the water level in the inner cavity of the water tank rises to close the second pressure relief hole, so that the water inlet mechanism stops water.

[0018] Preferably, it further includes a switching mechanism, which includes a switching element movable between a first position and a second position. When the switching element is in the first position, the water outlet channel supplies water to the brush ring water channel. When the switching element is in the second position, the switching element causes the water outlet channel to supply water to the inner cavity of the water tank.

[0019] Preferably, the water inlet mechanism has a water outlet end connected to the water outlet channel, and the switching mechanism includes a first water channel and a second water channel. The water outlet end is connected to the brush ring water channel through the first water channel under the action of the switching component, or the water outlet end is connected to the inner cavity of the water tank through the second water channel under the action of the switching component.

[0020] The present invention also proposes a toilet flushing method, including a toilet with a simple flushing device as described in any of the above claims, and further comprising the following steps:

[0021] a. Activate the second activation unit to turn on the water inlet mechanism. The water outlet channel of the water inlet mechanism supplies water to the brush ring water channel to flush the inner wall of the toilet bowl. After a first preset time, the water inlet mechanism is turned off.

[0022] b. Activate the first activation unit to open the drainage mechanism, the drainage mechanism opens the drainage channel, and the water inlet mechanism is activated again under the action of the first activation unit or the water level in the water tank cavity.

[0023] Preferably, in step b, when the first starting unit is activated, the first starting unit directly controls the water inlet mechanism to start before the drainage mechanism, or the first starting unit causes the second starting unit to control the water inlet mechanism to start before the drainage mechanism, so that the water outlet channel supplies water to the brush ring water channel, and the drainage mechanism opens after the water outlet channel supplies water to the brush ring water channel for a second preset time.

[0024] The beneficial effects of this invention are:

[0025] 1. This invention makes the control of the water inlet mechanism more flexible and diverse by setting two pressure relief holes on the back pressure chamber, which can meet the needs of different functions. It has a simple structure and reliable function.

[0026] 2. By activating the second activation unit, the inner wall of the toilet bowl can be pre-flushed and moistened to prevent dirt from sticking to the inner wall of the toilet bowl, making it easier to clean the inner wall of the toilet bowl and saving water. The structure is simple and the function is reliable.

[0027] 3. When the first starting unit is activated, the first starting unit directly controls the water inlet mechanism to start before the drainage mechanism, or the first starting unit causes the second starting unit to control the water inlet mechanism to start before the drainage mechanism, so that the water outlet channel supplies water to the brush ring channel, and the drainage mechanism opens after the water outlet channel supplies water to the brush ring channel for a second preset time, so that the brush ring channel completes the flushing of the inner wall of the toilet bowl before the main flushing channel of the toilet performs the main flush, and then the sewage on the inner wall of the toilet bowl is discharged through the sewage pipe during the main flush of the toilet, making the toilet flushing more thorough.

[0028] 4. This solution sets a switching mechanism on a single water inlet mechanism, allowing the water inlet mechanism to supply water to the brush ring through a shared back pressure chamber (and thus a shared water path and anti-siphon structure) and outlet channel to achieve pre-flushing or pre-flushing of the toilet bowl's inner wall. It can also supply water to the tank cavity for filling, thereby meeting the requirements for cleaning the toilet bowl in low-tank toilets. The existing brush ring water channel is used as a pre-flushing water channel for the toilet bowl's inner wall, resulting in a simple, compact, and reliable structure. Attached Figure Description

[0053] To make the technical problems, solutions, and beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the invention.

[0054] First embodiment: (Water inlet and drainage mechanisms are integrated)

[0055] like Figures 1 to 11 As shown, a toilet with a simple flushing device (not shown) includes a brush ring water channel (not shown) for flushing the inner wall of the toilet bowl (not shown) and a main flushing water channel (not shown) connected to the bottom of the toilet bowl, and also includes:

[0056] A water tank (not shown) has an inner cavity for storing flushing water, and the water tank is provided with a drainage channel (not shown) connecting the inner cavity of the water tank and the main flushing channel;

[0057] The water inlet mechanism 10 includes a water-stopping unit for opening or closing the water inlet mechanism 10. The water-stopping unit includes a back pressure chamber (not shown) with a first pressure relief hole 12 and a second pressure relief hole 13. When both the first pressure relief hole 12 and the second pressure relief hole 13 are closed, the water inlet mechanism 10 is closed. When at least one of the first pressure relief hole 12 and the second pressure relief hole 13 is open, the water inlet mechanism 10 is opened. When the water inlet mechanism 10 is open, the water outlet channel 11 of the water inlet mechanism 10 supplies water to the brush ring water channel or the inner cavity of the water tank. That is, the water inlet mechanism 10 in this embodiment is a back pressure structure. Under the action of the water pressure of the water inlet channel 17 and the water pressure chamber of the water inlet mechanism 10, it controls the movement of the water-stopping gasket (not shown) to connect or disconnect the water inlet channel 17 and the water outlet channel 11.

[0058] Drainage mechanism 20, which can open or close the drainage channel;

[0059] The first starting unit 50 is used to start the drainage mechanism 20 to open the drainage channel; when the first starting unit 50 is started, the drainage mechanism 20 opens the drainage channel.

[0060] In this embodiment, a second starting unit 40 is also included. The second starting unit 40 is used to start the water inlet mechanism 10 to turn on the water inlet. When the second starting unit 40 is turned on, the water outlet channel 11 supplies water to the brush ring water channel for a first preset time to flush the inner wall of the toilet bowl.

[0061] In this embodiment, when the first starting unit 50 is started, the water inlet mechanism 10 is opened under the action of the first starting unit 50.

[0062] In this embodiment, a switching mechanism 30 is also included. The switching mechanism 30 includes a switching member 31 that can move between a first position and a second position. When the switching member 31 is in the first position, the water outlet channel 11 supplies water to the brush ring water channel. When the switching member 31 is in the second position, the switching member 31 causes the water outlet channel 11 to supply water to the inner cavity of the water tank.

[0063] In this embodiment, when the first starting unit 50 is activated to control the water inlet mechanism 10 to open the water inlet, the water outlet channel 11 supplies water to the brush ring water channel and the inner cavity of the water tank in sequence under the action of the switching member 31, or the water outlet channel 11 supplies water directly to the inner cavity of the water tank under the action of the switching member 31.

[0064] In this embodiment, the water inlet mechanism 10 is provided with a water outlet end that is connected to the water outlet channel 11. The switching mechanism 30 includes a first water channel 32 and a second water channel 33. The water outlet end is connected to the brush ring water channel through the first water channel 32 under the action of the switching member 31, or the water outlet end is connected to the inner cavity of the water tank through the second water channel 33 under the action of the switching member 31.

[0065] In this embodiment, when the first starting unit 50 is activated, the water inlet mechanism is activated before the drainage mechanism 20 under the action of the first starting unit 50 or the second starting unit 40. The water outlet channel 11 supplies water to the brush ring water channel, and the drainage mechanism 20 is activated after the water outlet channel 11 supplies water to the brush ring water channel for a second preset time.

[0066] like Figure 2 , Figure 6 and Figure 7 As shown, in this embodiment, the switching mechanism 30 further includes a switching float 34 that is linked and cooperates with the switching component 31. The switching component 31 is specifically a switching plate. When the switching float 34 floats up under the action of buoyancy, it drives the switching component 31 to rotate, thereby opening the first water channel 32 and closing the second water channel 33. The water flow in the first water channel 32 flows into the brush ring water channel for flushing the inner wall of the toilet bowl. When the switching float 34 loses buoyancy and falls, it drives the switching component 31 to rotate in the opposite direction, thereby closing the first water channel 32 and opening the second water channel 33. The water flow in the second water channel 33 flows into the inner cavity of the water tank.

[0067] In this embodiment, the water-stopping unit also includes an electronic control component 14 and a float assembly 15. The electronic control component 14 opens or closes the first pressure relief hole 12 under the control of the circuit. The float assembly 15 includes a float 151. The float 151 rises or falls with the water level in the water tank cavity to drive the float assembly 15 to open or close the second pressure relief hole 13. Specifically, it also includes a lifting rod 152 that is linked to the float 151. One end of the lifting rod 152 is connected to the float 151, and the other end is provided with a sealing element to open or close the second pressure relief hole 13. Similarly, the electronic control component 14 is also provided with a sealing element for opening or closing the first pressure relief hole 12.

[0068] like Figure 8As shown, in this embodiment, when the second starting unit 40 is activated, the electronic control component 14 opens the first pressure relief hole 12 of the water inlet mechanism 10, so that the water outlet channel supplies water to the brush ring water channel for a first preset time. At this time, since the water tank is full of water, the switching float 34 is in a floating state. The switching component 31 is in the position of opening the first water channel 32 under the action of the switching float 34. Therefore, after the water inlet mechanism 10 is opened, the water outlet channel 11 supplies water to the brush ring water channel through the first water channel 32 for a first preset time to flush the inner wall of the toilet bowl. After the first preset time, the electronic control component 14 closes the first pressure relief hole 12 to stop the water inlet mechanism 10, thereby realizing the pre-flushing of the inner wall of the toilet bowl.

[0069] like Figure 10 and Figure 11 As shown, in this embodiment, when the first starting unit 50 is activated, the first starting unit 50 causes the second starting unit 40 to control the water inlet mechanism 10 to start before the drainage mechanism 20, or the first starting unit 50 directly controls the water inlet mechanism 10 to start before the drainage mechanism 20, so that the water outlet channel 11 supplies water to the brush ring water channel through the first water channel 32. After a second preset time, the drainage mechanism 20 opens the drainage channel. In this embodiment, when the first starting unit 50 is activated, the electronic control component 14 opens the first pressure relief hole 12, so that the water outlet channel 11 supplies water to the brush ring water channel. After a second preset time, the drainage mechanism 20 opens the drainage channel.

[0070] In this embodiment, the drainage mechanism 20 includes a valve core 21 that opens or closes the drainage channel. The float assembly 15 is linked with the valve core 21 or the first starting unit 50. When the first starting unit 50 is activated, the drainage mechanism 20 opens to drain water, and the second pressure relief hole 13 opens to allow water to enter the water inlet mechanism 10. The water flow from the outlet channel 11 flows through the first water channel 32 to the brush ring water channel. After the drainage mechanism 20 drains water, when the float 34 drops with the water level in the water tank cavity, it drives the switching member 31 to rotate in the opposite direction, thereby closing the first water channel 32 and opening the second water channel 33. This allows the outlet channel 11 to supply water to the water tank cavity through the second water channel 33. The electronic control assembly 14 controls the first pressure relief hole 12 to close before the second pressure relief hole 13 closes. As the second water channel 33 continuously supplies water to the water tank cavity, the float 151 rises with the water level in the water tank cavity to close the second pressure relief hole 13, thus stopping the water inlet mechanism 10.

[0071] like Figure 9As shown, this embodiment can also employ the following method: when the first starting unit 50 is activated, the first pressure relief hole 12 and / or the second pressure relief hole 13 are opened, and the drainage mechanism 20 opens the drainage channel. When the first pressure relief hole 12 and / or the second pressure relief hole 13 are opened, the water flow from the outlet channel 11 flows through the first water channel 32 to the brush ring water channel. After the drainage mechanism 20 drains, when the switching float 34 falls with the water level in the water tank cavity, it drives the switching member 31 to rotate in the opposite direction, thereby closing the first water channel 32 and opening the second water channel 33. This allows the outlet channel 11 to supply water to the water tank cavity through the second water channel 33. Furthermore, the float 151 rises with the water level in the water tank cavity to close the second pressure relief hole 13, thereby stopping the water inlet mechanism 10.

[0072] Alternatively, in this embodiment, when the first starting unit 50 is started, the drainage mechanism 20 opens the drainage channel, and the water inlet mechanism 10 starts water intake under the action of the water level in the water tank cavity. Specifically, after the drainage mechanism 20 drains water, the float 151 drops with the water level in the water tank cavity to open the second pressure relief hole 13 so that the water inlet mechanism 10 starts water intake.

[0073] In this embodiment, the second activation unit 40 preferably adopts a sensing mechanism. The second activation unit 40 includes a sensor installed on the toilet seat. When the sensor detects that someone sits down, the second activation unit 40 provides a control signal to the electronic control component 14 to open the first pressure relief hole 12. Of course, the second activation unit 40 can also provide a control signal to the electronic control component 14 when the sensor detects that someone enters the sensing area, or when the second activation unit 40 detects a waving hand or other action in the sensing area. Alternatively, the second activation unit 40 includes a remote control, and provides a control signal to the electronic control component 14 when the pre-wash button on the remote control is pressed. Or, the second activation unit 40 provides a control signal to the electronic control component 14 when the toilet seat is flipped.

[0074] In this embodiment, the first starting unit 50 adopts a sensor module combined with a mechanical button structure. The first starting unit 50 controls the opening of the first pressure relief hole 12 in the following two ways:

[0075] Method 1: When the sensor on the toilet seat of the first starting unit 50 detects that a person has left, the first starting unit 50 provides a control signal to the second starting unit 40, and then the second starting unit 40 provides a control signal to the electronic control component 14 so that the electronic control component 14 opens the first pressure relief hole 12 of the water inlet mechanism 10, thereby starting the water inlet mechanism 10.

[0076] Method 2: When the sensor on the toilet seat of the first starting unit 50 detects that a person has left, the first starting unit 50 directly provides a control signal to the electronic control component 14 so that the electronic control component 14 opens the first pressure relief hole 12 of the water inlet mechanism 10, thereby starting the water inlet mechanism 10.

[0077] Of course, the action of driving the first starting unit 50 to start can also be achieved by the sensor sensing a waving motion in the sensing area, or by pressing the drain button on the remote control, or by flipping the toilet seat, etc.

[0078] In this embodiment, the water inlet mechanism 10 and the drainage mechanism 20 adopt an integrated water inlet and drainage valve structure. The float assembly 15 is linked with the valve core 21. The valve core 21 is linked with the lifting rod 152 of the float assembly 15 through a connecting rod assembly 22. This allows the water inlet mechanism 10 to start water in while the drainage mechanism 20 starts draining water.

[0079] The specific working process of this embodiment is as follows:

[0080] Before using the toilet, it is necessary to pre-wash and moisten the inner wall of the toilet bowl, such as... Figure 8 As shown, when the sensor on the toilet seat of the second activation unit 40 detects someone sitting down, the second activation unit 40 is activated, thereby controlling the electronic control component 14 to open the first pressure relief hole 12, causing the water inlet mechanism 10 to start water intake. At this time, since the water tank is full of water, the float switch 34 is in a floating state, and the switching component 31 is in the first position, so that the water outlet channel 11 supplies water to the brush ring channel through the first water channel 32 (e.g., Figure 6 As shown), the toilet bowl's inner wall is pre-flushed, which wets the inner wall, making it less likely for dirt to stick to it. After a first preset time, the electronic control component 14 closes the first pressure relief hole 12 to stop the water inlet mechanism 10.

[0081] When you need to flush the toilet after using it, such as Figure 10As shown, when the sensor on the toilet seat of the first starting unit 50 senses that a person has left, the first starting unit 50 provides a control signal to the second starting unit 40, so that the second starting unit 40 causes the electronic control component 14 to open the first pressure relief hole 12, or the first starting unit 50 directly causes the electronic control component 14 to open the first pressure relief hole 12. At this time, the switching component 31 is still in the first position, so that the water outlet channel 11 supplies water to the brush ring channel through the first water channel 32. After a second preset time, the drainage mechanism 20 opens the drainage channel. At the same time that the drainage mechanism 20 opens the drainage, the second pressure relief hole 13 opens. As the water level in the water tank decreases, the switching float 34 falls due to reduced or lost buoyancy, thereby driving the switching component 31 to rotate, so that the switching component 31 closes the first water channel 32 and opens the second water channel 33 (e.g., Figure 7 As shown), the water inlet mechanism 10 starts to supply water to the inner cavity of the water tank to refill the water tank. The program is set so that the electronic control component 14 controls the first pressure relief hole 12 to close before the second pressure relief hole 13 closes. The float 151 rises with the water level in the inner cavity of the water tank to close the second pressure relief hole 13, so that the water inlet mechanism 10 stops the water flow.

[0082] Second embodiment: (The water inlet mechanism and the drainage mechanism are set up independently)

[0083] like Figures 12 to 19 As shown, the difference between this embodiment and the above embodiment is that the water inlet mechanism 10 and the drainage mechanism use independently set water inlet valves and drainage valves, and the float assembly 15 and the valve core 21 are not linked together, as shown. Figure 18 and Figure 19 As shown, when the first starting unit 50 is started, the float 151 opens the second pressure relief hole 13 as the water level in the inner cavity of the water tank falls, so that the water inlet mechanism 10 can start water intake. The electronic control component 14 controls the first pressure relief hole 12 to close before the second pressure relief hole 13 closes. The float 151 closes the second pressure relief hole 13 as the water level in the inner cavity of the water tank rises, so that the water inlet mechanism 10 stops water.

[0084] Third embodiment: (Switching mechanism with injection function)

[0085] like Figures 20 to 23As shown, the difference between this embodiment and the first embodiment is that the switching mechanism 30 in this embodiment further includes a spray pipe 36 and a nozzle 35 connected to the water outlet channel 11. The nozzle 35 and the spray pipe 36 are spaced apart, and the two ends of the spray pipe 36 are respectively connected to the brush ring water channel and the inner cavity of the water tank. When the water flow sprayed from the nozzle 35 sprays onto the spray pipe 36, it can bring the water in the inner cavity of the water tank into the spray pipe 36. The switching component 31 is disposed on the spray pipe 36, so that the water outlet channel 11 is sprayed to the brush ring water channel or the inner cavity of the water tank through the nozzle 35. This structure is the prior art and will not be described in detail here.

[0086] The present invention also proposes a toilet flushing method using a toilet with a simple flushing device according to any of the above embodiments, which includes the following steps:

[0087] a. Activate the second activation unit 40 to open the water inlet mechanism 10. The water outlet channel 11 of the water inlet mechanism 10 supplies water to the brush ring water channel to flush the inner wall of the toilet bowl.
