Description

Technical Field

[0001] The invention relates to the technical field of sanitary products, and in particular to a flushing control method of an intelligent toilet. Background Art

[0002] Smart toilets are generally flushed through multiple flushing ports to clean the inner wall of the toilet base of the smart toilet, including an upper flushing port set at the top of the toilet base and a lower flushing port set at the bottom of the toilet base. The upper / lower flushing ports of the smart toilet are generally equipped with upper / lower nozzles. The flushing water is respectively transported to the upper / lower nozzles through the water pipes and sprayed out from the water outlet holes of the upper / lower nozzles to clean the inner wall of the toilet base of the smart toilet.

[0003] At present, although the upper / lower nozzles of smart toilets in the industry have certain conflicts in flushing performance, flushing posture and noise, and meet excellent performance, there are still problems of splashing, backflow and loud noise during the flushing process. Therefore, most manufacturers in the industry can only set relevant performance according to national standards. However, with the continuous update of product strength, consumers have higher and higher requirements for smart toilet products, and products that only meet national standards can no longer be well recognized by consumers.

[0004] Specifically, the upper nozzle in the prior art mainly increases the flow rate by reducing the water outlet diameter, thereby achieving the purpose of increasing the impact force. However, after the flow rate increases, the water flow rate of the brush ring is too fast, and it is easy to splash out when washing the inner wall of the toilet base; at the same time, after the flow rate increases, the water flow ejected from the upper nozzle (i.e., the water outlet hole inside the upper nozzle) is columnar, and it is impossible to form a "paved" washing shape on the inner wall of the toilet base, resulting in the inability to clean the local area. In addition, the flushing control method of the smart toilet in the prior art is a segmented control, that is, the flushing water sprayed by the upper nozzle and the jet water sprayed by the lower nozzle are released alternately, but the segmented flushing control method is prone to the phenomenon of not flushing cleanly due to the asynchronous release of the flushing water and the jet water flow, which is not conducive to improving the user experience. Summary of the invention

[0005] The purpose of the present invention is to propose a flushing control method for an intelligent toilet, which can effectively solve the technical problem of the existing segmented flushing control method that the flushing water and the jet water are not released synchronously, resulting in the phenomenon of incomplete flushing.

[0032] The technical solution of the present invention is further illustrated below through specific implementation methods.

[0033] A flushing control method for an intelligent toilet is applied to a flushing structure of an intelligent toilet, wherein the flushing structure of the intelligent toilet comprises a toilet seat 1, an upper nozzle 2 and a lower nozzle 3; the toilet seat 1 comprises an integrally formed base 11 and a toilet ring 12, and the toilet ring 12 is located at the top of the base 11, a rotary flushing water channel 13 is provided inside the toilet ring 12, a plurality of water outlets 1321 interconnected with an inner cavity of the toilet seat 1 are provided at the bottom of the rotary flushing water channel 13, and the water outlet directions of the plurality of water outlets 1321 are all located in the same clockwise direction; the upper nozzle 2 is installed at the top of the toilet seat 1, and the water outlet end of the upper nozzle 2 is connected to the water inlet of the rotary flushing water channel 13; the lower nozzle 2 is installed at the bottom of the inner cavity of the toilet seat 3, and the water outlet end of the lower nozzle 2 faces the rear side of the toilet seat 1;

[0034] The flushing structure of the smart toilet also includes a water tank 4, a water pump 5 and a tee pipe 6 which are sequentially connected by pipes, and the water tank 4, the water pump 5 and the tee pipe 6 are all located at the rear side of the base 11; the tee pipe 6 includes a first outlet 61 and a second outlet 62, the first outlet 61 is connected to the water inlet end of the upper nozzle 3, the second outlet 62 is connected to the water inlet end of the lower nozzle 2, and the diameter of the first outlet 61 is greater than the diameter of the second outlet 62;

[0035] The flushing control method comprises the following steps:

[0036] S1, turning on the water pump 5, and making the flow rate of the water pump 5 reach the peak flow rate when running, and continuing for a preset time T1;

[0037] S2, making the lift of the water pump 5 reach the peak lift value during operation, and continuing for a preset time T2;

[0038] S3, turning off the water pump 5.

[0039] The upper nozzle in the prior art mainly increases the flow rate by reducing the water outlet diameter, thereby achieving the purpose of increasing the impact force. However, after the flow rate increases, the water flow rate of the brush ring is too fast, and it is easy to splash when washing the inner wall of the toilet base; at the same time, after the flow rate increases, the water flow ejected from the upper nozzle (i.e. the water outlet hole inside the upper nozzle) is columnar, and it is impossible to form a "surface" washing shape on the inner wall of the toilet base, resulting in the inability to clean the local area.

[0040] Therefore, in order to solve the above technical problems, this technical solution proposes a flushing structure of a smart toilet, such as Figure 1-3 As shown, it includes a toilet seat 1, an upper nozzle 2, a lower nozzle 3, a water tank 4, a water pump 5 and a three-way pipe 6. Among them, the present solution particularly adds a three-way pipe 6 inside the toilet seat 1, and realizes the distribution of different water volumes of the upper nozzle 2 and the lower nozzle 3 through the first outlet 61 and the second outlet 62 of the three-way pipe 6 with different diameters, so that a larger upper flushing water volume can simulate the effect of pouring water into the toilet with a bucket, so as to form a siphon effect instantly, and a smaller lower flushing water volume is used to assist in "pushing" the dirt to the inner cavity outlet, so as to achieve an excellent siphon effect; moreover, the present solution realizes the distribution of the upper flushing water volume and the lower flushing water volume through the design of the above structure, which is also conducive to avoiding the splashing phenomenon during the flushing process while ensuring the washing effect, and further reducing the problem of flushing noise, so as to overcome the shortcomings of the prior art.

[0041] Furthermore, the bottom of the rotary flushing water channel 13 of the present invention is provided with a plurality of water outlets 1321 which are interconnected with the inner cavity of the toilet seat 1, and the water outlet directions of the plurality of water outlets 1321 are all located in the same clockwise direction, that is, the water outlet directions of the plurality of water outlets 1321 are all located in the clockwise direction or the counterclockwise direction, so that when flushing, a vortex brush circle water flow rotating in the clockwise direction or the counterclockwise direction can be formed in the inner cavity of the toilet seat 1, such as Figure 4-5 As shown in the direction of the arrow, the fluid in the toilet seat 1 can have a certain potential energy, similar to the "tornado" effect, which is more conducive to the fluid rotating the dirt in the toilet seat 1, thereby discharging the dirt out of the inner cavity.

[0042] In addition, the flushing control method of the smart toilet in the prior art is a segmented control, that is, the flushing water sprayed from the upper nozzle and the jet water sprayed from the lower nozzle are released alternately. However, the segmented flushing control method is prone to incomplete flushing due to the asynchronous release of the flushing water and the jet water flow, which is not conducive to improving the user experience.

[0043] Therefore, the present technical solution also proposes a flushing control method for an intelligent toilet using the above-mentioned flushing structure. Due to the optimization of the flushing structure of the present solution, the flushing water sprayed by the upper nozzle and the jetting water sprayed by the lower nozzle can be released synchronously; at the same time, in order to improve the flushing ability of the intelligent toilet, the present solution divides the flushing control method into two stages, the first is the siphon generation stage of step S1, and the second is the sewage discharge stage of step S2.

[0044] In the siphon generation stage, the flow rate of the water pump 5 is adjusted to the peak flow rate during operation, so that the flushing water and the jet water can instantly fill the inner cavity of the toilet seat 1, and then continue for a preset time T1, so as to quickly increase the water seal of the inner cavity and produce a siphon effect; after the siphon effect is generated, the head of the water pump 5 is adjusted to the peak head and continued for a preset time T2, so as to increase the pushing force of the siphon, so that the dirt in the inner cavity of the toilet seat 1 can be flushed away under the superposition of flushing water and jet water, thereby solving the technical problem of the existing segmented flushing control method that the flushing water and the jet water are not released synchronously, resulting in the phenomenon of not flushing cleanly.

[0045] It should be noted that since the flow rate and head of the water pump 5 are interrelated with the power curve of the water pump, in some embodiments, when the flow rate of the water pump 5 reaches the flow peak or the head reaches the head peak, the corresponding head and flow rate can be adapted according to the product specifications of the water pump 5, which is not limited here.

[0046] To further illustrate, in step S1, 3s≤T1≤10s; in step S2, 3s≤T2≤10s.

[0047] In order to improve the siphon effect of the flushing control method in the siphon generation stage and the pushing force in the sewage discharge stage, this scheme also optimizes the duration of the two stages to ensure the flushing effect of the flushing control method.

[0048] To further illustrate, in step S1, T1=4s; in step S2, T2=3s.

[0049] To further illustrate, the peak flow rate of the water pump 5 is 95 L / min, and the peak lift of the water pump 5 is 5 m.

[0050] To further explain, in step S1, when the flow rate of the water pump 5 reaches the peak flow rate, the lift of the water pump 5 is 1.5 m.

[0051] In a preferred embodiment of the present technical solution, by controlling the duty ratio of the three working conditions of the power, flow rate and head of the water pump 5, the flow rate when the water pump 5 is running is adjusted to reach the peak flow rate and the head value of the water pump 5, so as to further enhance the siphon effect in the siphon generation stage.

[0052] To further explain, in step S2, when the lift of the water pump 5 reaches the peak lift, the flow rate of the water pump 5 is 60 L / min.

[0053] In another preferred embodiment of the present technical solution, by controlling the duty ratio of the three working conditions of the power, flow rate and head of the water pump 5, the head of the water pump 5 is adjusted to reach the peak head value when it is running, and the flow value of the water pump 5 is adjusted to further enhance the pushing force in the sewage discharge stage and ensure the sewage discharge effect in the sewage discharge stage.

[0054] To further illustrate, the ratio between the diameter of the first outlet 61 and the diameter of the second outlet 62 is (6-7):(3-4).

[0055] In one embodiment of the present technical solution, the ratio between the diameter of the first outlet 61 and the diameter of the second outlet 62 in the flushing structure is optimized to obtain a better siphon effect.

[0056] Preferably, the ratio between the diameter of the first outlet 61 and the diameter of the second outlet 62 is 6.5:3.5.

[0057] To further explain, the water outlet 1321 is circular in shape.

[0058] Under the premise of a certain water flow rate, a circular shape is the best diameter, which is conducive to uniform fluid distribution and avoids turbulence.

[0059] Further, the rotary flushing water channel 13 includes a main water channel 131 and an outlet water channel 132 that are interconnected. A plurality of outlet water channels 132 are provided, and the plurality of outlet water channels 132 are protrudingly provided at intervals at the bottom of the main water channel 131. The bottom surface of the outlet water channel 132 is inclined downward along the water outlet direction, and the outlet 1321 is provided at the end of the outlet water channel 132 along the water outlet direction. In this way, the potential energy of the upward flushing water flow is more conducive to being formed and released in the toilet seat 1.

[0060] Further, at least two water outlet channels 132 are provided. In this way, it is more conducive to forming a brush ring water flow with a larger water distribution area in the inner cavity of the toilet seat 1, so that the brush ring water flow covers the entire inner cavity of the toilet seat 1.
