Description

Technical Field

[0001] The present invention relates to the technical field of toilet flushing, and particularly to a toilet flushing control method, a water tank device and a toilet bowl. Background Art

[0002] In modern bathroom design, the flushing system of a toilet is a crucial component. Currently, most toilets use a switching valve to achieve different types of flushing functions, such as rim flushing and jet flushing. Rim flushing is usually used to clean the inner wall of the toilet, while jet flushing is for a powerful rinse of the dirt at the bottom of the toilet. Since rim flushing and jet flushing operate independently, when the dirt in the toilet is washed away, the jet water flow will be directly exposed to the air, and the resulting noise affects the user experience; at the same time, the configuration of the switching valve increases the manufacturing cost of the toilet, the applicable range is limited, and it is not conducive to market competition. Summary of the Invention

[0003] The present invention provides a toilet flushing control method, a water tank device and a toilet bowl, aiming to still meet the usage requirements of rim flushing and jet flushing without configuring a switching valve.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A toilet flushing control method is used to control a pressurizing device. The water outlet of the pressurizing device is connected to a rim water outlet and a jet water outlet. After receiving a flushing instruction, the pressurizing device operates in a first state for a time T1, then in a second state for a time T2, and finally in a third state for a time T3 and then shuts down. The rim water outlet and the jet water outlet discharge water simultaneously. The water discharge flow rate of the pressurizing device in the first state and the third state is less than the water discharge flow rate of the pressurizing device in the second state.

[0006] Further, the rotation speed of the pressurizing device in the first state and the third state is less than the rotation speed of the pressurizing device in the second state; or, the duty cycle of the pressurizing device in the first state and the third state is less than the duty cycle of the pressurizing device in the second state.

[0007] Further, when powered by municipal power supply, when the pressurizing device receives a pre-wetting instruction, the pressurizing device operates in a fourth state and a fifth state in sequence. The water discharge flow rate of the pressurizing device in the fourth state is less than the water discharge flow rate of the pressurizing device in the fifth state.

[0008] Further, the operation time of the fourth state is S1, and the operation time of the fifth state is S2, where 0.3 s ≤ S1 ≤ 2 s and 0.3 s ≤ S2 ≤ 1 s.

[0009] Further, the cumulative water consumption for pre-wetting is not greater than 500 mL.

[0010] A water tank device includes a water tank body. An inlet device is provided inside the water tank body. It further includes a pressurizing device and a first adapter that are connected in sequence along the water outlet direction. The pressurizing device is applicable to the toilet flushing control method described above. It also includes a second adapter. The second adapter is provided with a water inlet, a first water outlet, and a second water outlet that communicate with the water inlet. The first water outlet supplies water flow to the brush ring, and the second water outlet supplies jet water flow. The water inlet is connected to the first adapter, and the internal channels of the first adapter and the second adapter form a flushing channel.

[0011] Further, the first water outlet is connected to the brush ring nozzle through a brush ring pipeline, and the second water outlet is connected to the jet nozzle through a jet pipeline. Among them, the cross-sectional area of the first water outlet is S1, the cross-sectional area of the second water outlet is S2, and S1 < S2. The cross-sectional area of the brush ring nozzle is S3, the cross-sectional area of the jet nozzle is S4, the cross-sectional area of the brush ring pipeline is S5, and the cross-sectional area of the jet pipeline is S6. The relationship between the cross-sectional areas satisfies 1 / 16 ≤ (S1 × S3 × S5) / (S2 × S4 × S6) ≤ 1 / 4, and 30mm 2 ≤ S3 ≤ 120mm 2 .

[0012] Further, it also includes an energy storage device for providing power to the pressurizing device in case of power failure.

[0013] Further, the first adapter is provided with an air inlet hole that communicates with the flushing channel.

[0014] Further, the first adapter is provided with a plurality of first connection holes, and the second adapter is provided with second connection holes. The second connection holes are adapted to any one of the first connection holes to adjust the angle between the first adapter and the second adapter.

[0015] A toilet includes a toilet body, and the water tank device described above is installed on the toilet body.

[0016] The beneficial effects of the present invention are:

[0017] 1. A toilet flushing control method proposed by the present invention. After the pressurizing device receives a flushing instruction, it operates in a first state for a time T1, then in a second state for a time T2, and finally in a third state for a time T3 and then shuts down. The brush ring water outlet and the jet water outlet discharge water simultaneously. The water discharge flow rate of the pressurizing device in the first state and the third state is less than that in the second state. The first state is used to discharge the air in the pipeline and supplement the water seal inside the toilet. The second state is used to flush the toilet wall surface and generate a siphon to take away the dirt. The third state is used to supplement the toilet water seal to play an anti-odor role. During the operation of the pressurizing device, the brush ring water outlet and the jet water outlet discharge water simultaneously. The noise generated by the brush ring water covering the jet water is reduced, improving the user experience. At the same time, compared with the conventional flushing system, the switching valve is reduced, saving installation space and reducing costs.

Detailed implementation manners

[0034] Embodiment 1

[0035] The following is combined with Figure 1 - Figure 2 to describe the present invention in detail.

[0036] A toilet flushing control method is used to control the pressurizing device 40. The water outlet of the pressurizing device 40 is communicated with the brush ring water outlet and the jet water outlet. After receiving the flushing instruction, the pressurizing device 40 operates in the first state for a time T1, then operates in the second state for a time T2, and finally operates in the third state for a time T3 and then closes. The brush ring water outlet and the jet water outlet discharge water simultaneously. The water discharge flow rate of the pressurizing device 40 in the first state and the third state is less than the water discharge flow rate of the pressurizing device 40 in the second state.

[0037] In this embodiment, the first state is used to discharge the air in the pipeline and replenish the water seal inside the toilet bowl. The second state is used to flush the inner wall of the toilet bowl and generate a siphon to carry away the dirt. The third state is used to replenish the water seal of the toilet bowl to prevent odors from coming back. During the operation of the pressurizing device 40, water flows out from both the brush ring water outlet and the jet water outlet simultaneously. The water flowing out from the brush ring covers the noise generated by the jet water outlet, improving the user experience. At the same time, compared with the conventional flushing system, the switching valve is reduced, saving installation space and reducing costs.

[0038] In this embodiment, the pressurizing device 40 is used for zero-water-pressure pressurized flushing, that is, the water in the water tank is pressurized to generate a water flow. Specifically, the pressurizing device 40 is a pump with an adjustable duty cycle. The duty cycle is the ratio of the energization time to the total time. Therefore, the higher the duty cycle, the longer the energization time, and the higher the water flow rate. The duty cycles of the pressurizing device 40 in the first state, the second state, the third state, the fourth state, and the fifth state are m1, m2, m3, m4, and m5 respectively. Therefore, when m1 < m3 and m2 < m3, the water flow rates of the pressurizing device 40 in the first state and the third state are less than the water flow rate of the pressurizing device 40 in the second state; when m4 < m5, the water flow rate of the pressurizing device 40 in the fourth state is less than the water flow rate of the pressurizing device 40 in the fifth state. Further, the operation time of the fourth state is S1, and the operation time of the fifth state is S2, where 0.3s ≤ S1 ≤ 2s, 0.3s ≤ S2 ≤ 1s, and the cumulative water consumption for pre-wetting is not greater than 500 mL.

[0039] In other embodiments, the pressurizing device 40 is a pump with an adjustable operating power, and different powers correspond to different rotational speeds. The rotational speeds of the pressurizing device 40 in the first state, the second state, the third state, the fourth state, and the fifth state are n1, n2, n3, n4, and n5 respectively. Therefore, when n1 < n3 and n2 < n3, the water flow rates of the pressurizing device 40 in the first state and the third state are less than the water flow rate of the pressurizing device 40 in the second state; when n4 < n5, the water flow rate of the pressurizing device 40 in the fourth state is less than the water flow rate of the pressurizing device 40 in the fifth state.

[0040] In this embodiment, when the pressurizing device 40 is at full duty cycle or full rotational speed, its water flow rate range is 40 L / min - 60 L / min, where full duty cycle means the pressurizing device 40 runs continuously with power on, and full rotational speed means the pressurizing device 40 always runs at the highest rotational speed.

[0041] A toilet flushing control method proposed in this embodiment is as Figure 1 shown, and its flushing steps are as follows:

[0042] S1. The pressurizing device 40 receives a flushing instruction;

[0043] S2. The pressurizing device 40 first operates in the first state for a time T1. At this time, water flows out from both the brush ring water outlet and the jet water outlet, but the water flow rate is small and not enough to generate a siphon effect. This is used to discharge the air in the pipeline and replenish the water seal inside the toilet.

[0044] S3. After operating for the time T1, the pressurizing device 40 operates in the second state for a time T2. At this time, water flows out from both the brush ring water outlet and the jet water outlet, and the water flow rate is large. This is used to flush the toilet wall surface and generate a siphon to carry away the dirt.

[0045] S4. After operating for the time T2, the pressurizing device 40 operates in the third state for a time T3. At this time, water flows out from both the brush ring water outlet and the jet water outlet, but the water flow rate is small, and it replenishes the water seal inside the toilet to play an anti-odor role.

[0046] S5. After operating for the time T3, the pressurizing device 40 is turned off. After the pressurizing device 40 receives a flushing instruction again, steps S2 - S4 are repeated.

[0047] Embodiment Two

[0048] The following combines Figure 3 - Figure 9 to describe the present invention in detail.

[0049] This embodiment provides a water tank device 10, which includes a water tank body 20. An inlet device 30 is arranged inside the water tank body 20, and the inlet device 30 generally adopts an inlet valve. It also includes a pressurizing device 40 and a first adapter 60 that are connected in sequence along the water outlet direction. The pressurizing device 40 and the first adapter 60 are connected through a connecting pipe 80. The pressurizing device 40 is applicable to the toilet flushing control method described above. It also includes a second adapter 70. The second adapter 70 is provided with a water inlet 701, a first water outlet 702 and a second water outlet 703 that communicate with the water inlet 701. The first water outlet 702 supplies water for the brush ring, and the second water outlet 703 supplies jet water. The water inlet 701 communicates with the first adapter 60. The internal channels of the first adapter 60 and the second adapter 70 form a flushing channel. It also includes a fixing bracket 50, and the fixing bracket 50 fixes the pressurizing device 40 at the inner bottom of the water tank.

[0050] For the water tank device 10 proposed in this embodiment, the pressurizing device 40 is used to pressurize the water flow, so that the toilet flushing is not affected by the water pressure. During flushing, water flows out from both the first water outlet 702 and the second water outlet 703 simultaneously, that is, water flows out from both the brush ring water outlet and the jet water outlet simultaneously. The water flowing out from the brush ring covers the noise generated by the jet water outlet, improving the user experience. At the same time, compared with the conventional flushing system, the switching valve is reduced, saving installation space and reducing costs.

[0051] In this embodiment, the first water outlet 702 is connected to the brush ring nozzle through a brush ring pipeline, and the second water outlet 703 is connected to the injection nozzle through an injection pipeline. Among them, the cross-sectional area of the first water outlet 702 is S1, the cross-sectional area of the second water outlet 703 is S2, and S1 < S2.

[0052] In this embodiment, the cross-sectional area of the brush ring nozzle is S3, the cross-sectional area of the injection nozzle is S4, the cross-sectional area of the brush ring pipeline is S5, and the cross-sectional area of the injection pipeline is S6. The following relationship is satisfied among the cross-sectional areas: 1 / 16 ≤ (S1 × S3 × S5) / (S2 × S4 × S6) ≤ 1 / 4, and 30mm 2 ≤ S3 ≤ 120mm 2 .

[0053] In this embodiment, an energy storage device is further included, which is used to provide power for the pressurization device in case of power outage.

[0054] In this embodiment, at the second water outlet 703 of the second adapter 70, a locking member 704 for locking the injection pipeline is provided. The first adapter 60 is provided with an air inlet hole 601 communicating with the flushing channel. As Figure 7 shown, when the flushing work is completed, air can enter the flushing waterway through this hole, avoiding the reverse flow of water to the water tank due to negative pressure in the flushing waterway and preventing the water tank from being polluted. Further, the first adapter 60 is provided with a first connection hole 602, as Figure 5 shown. The second adapter 70 is provided with a second connection hole 705 adapted to the first connection hole 602. As Figure 9 shown, a fastener passes through the first connection hole 602 and the second connection hole 705, thereby connecting the first adapter 60 and the second adapter 70. Further, the first adapter 60 can also be provided with multiple first connection holes 602, and the second connection hole 705 is adapted to any one of the first connection holes 602, so as to adjust the angle between the first adapter 60 and the second adapter 70 to meet the installation requirements at different angles.
