Description

Technical Field

[0001] This invention relates to the field of sanitary ware, and in particular to a water outlet control system and its control method. Background Technology

[0002] As people's living standards improve, the diversification of smart toilet functions is becoming increasingly popular. Currently, the most common cleaning functions of smart toilets are posterior washing and feminine washing. Moreover, existing cleaning functions usually have multiple water pressure / flow levels. However, the current technology uses the same channel to deliver water at different water pressure / flow levels, which can cause discomfort for users under high pressure / high flow or inadequate cleaning under low pressure / low flow.

[0003] To address the above-mentioned shortcomings, this invention proposes a toilet water output control method that is simple in structure and has multiple cleaning modes. Summary of the Invention

[0004] To solve the above problems, the present invention is achieved through the following technical solution:

[0005] A water discharge control system, comprising:

[0006] The switching unit includes a water inlet channel, a T1 water circuit, and a T2 water circuit, wherein the water inlet channel switches the water supply to the T1 water circuit and the T2 water circuit.

[0007] The controller has a first flow rate setting and a second flow rate setting for adjusting the flow rate of the water inlet channel;

[0008] A water spray body, the water spray body having a first water spray channel and a second water spray channel, the first water spray channel being connected to the T1 water circuit, and the second water spray channel being connected to the T2 water circuit;

[0009] Specifically, when the controller adjusts the flow rate of the water inlet channel to the first flow rate level, the water inlet channel is connected to the T2 water circuit; when the controller adjusts the flow rate of the water inlet channel to the second flow rate level, the water inlet channel is connected to the T1 water circuit.

[0010] Furthermore, the water spray body also includes a first water nozzle that is connected to the first water spray channel and the second water spray channel respectively; the first water spray channel sprays water in a first form through the first water nozzle, and the second water spray channel sprays water in a second form through the first water nozzle.

[0011] Furthermore, the water spray body also includes a rectifier cavity. The water inlet of the second water spray channel is tangential to the inner wall of the rectifier cavity or at a preset angle. The water flow accelerates and rotates in the rectifier cavity before being sprayed out as dispersed particulate water through the first water spray nozzle. The water inlet of the first water spray channel is radial along the rectifier cavity. The water flow is rectified and sprayed out as columnar particulate water through the rectifier column in the rectifier cavity.

[0012] Furthermore, the switching unit also includes F1 water path and F2 water path, and the water inlet channel can switch the water supply to F1 water path and F2 water path; the water spray body has a third water spray channel and a fourth water spray channel, the third water spray channel is connected to the F1 water path, and the fourth water spray channel is connected to the F2 water path.

[0013] Furthermore, the controller includes a first function key that can realize a first function and a second function key that can realize a second function. When the controller selects the first function and the first flow rate setting, the water inlet channel is connected to the T2 water circuit; when the controller selects the first function and the second flow rate setting, the water inlet channel is connected to the T1 water circuit; when the controller selects the second function and the first flow rate setting, the water inlet channel is connected to the F2 water circuit; when the controller selects the second function and the second flow rate setting, the water inlet channel is connected to the F1 water circuit.

[0014] Furthermore, the water spray body also includes a second water nozzle that is connected to the third water spray channel and the fourth water spray channel respectively; the third water spray channel sprays out water spray of a third form through the second water nozzle, and the fourth water spray channel sprays out water spray of a fourth form through the second water nozzle.

[0015] Furthermore, the switching unit also includes a primary water distribution valve and a secondary water distribution valve. The primary water distribution valve is connected to the water inlet channel, the T1 water circuit, the F1 water circuit, and the Z1 water circuit, respectively. The water inlet channel is switched to be connected to the T1 water circuit, the F1 water circuit, and the Z1 water circuit via the primary water distribution valve. The secondary water distribution valve is connected to the connecting channel, the T2 water circuit, and the F2 water circuit, respectively. The connecting channel is switchably connected to the T2 water circuit and the F2 water circuit. The Z1 water circuit is connected to the connecting channel.

[0016] Furthermore, the secondary water distribution valve is connected to the Z2 water path, and the connection channel can be switched to be connected to the Z2 water path; the Z2 water path is a self-cleaning water path for cleaning the spray body.

[0017] Furthermore, the water outlet control system executes the cleaning function at the first flow rate level in the following steps:

[0018] S1, the initial position of the first-stage water distribution valve is the Z1 water circuit, and the initial position of the second-stage water distribution valve is the Z2 water circuit;

[0019] S2. When the remote control selects the first flow rate setting, the primary water distribution valve stays at the Z1 water inlet, and the secondary water distribution valve switches to the T2 or F2 water inlet for cooling.

[0020] S3. After the cooling is completed, the secondary water distribution valve switches to the Z2 water circuit to perform self-cleaning of the spray body's extension rod;

[0021] S4. After self-cleaning is completed, the secondary water distribution valve switches to the F2 water circuit or the T2 water circuit, and sprays water in the fourth form through the fourth water spray channel connected to the F2 water circuit or sprays water in the second form through the second water spray channel connected to the T2 water circuit.

[0022] Furthermore, the water control system executes the cleaning function at the second flow rate level in the following steps:

[0023] S1, the initial position of the first-stage water distribution valve is the Z1 water circuit, and the initial position of the second-stage water distribution valve is the Z2 water circuit;

[0024] S2. When the remote control selects the second flow rate setting, the secondary water distribution valve stays at the Z2 water inlet, and the primary water distribution valve switches to the T1 water circuit or the F1 water circuit for cooling.

[0025] S3. After the cooling is completed, the first-stage water distribution valve switches to the Z1 water circuit to perform self-cleaning of the extension rod of the water spray body;

[0026] S4. After self-cleaning is completed, the first-level water distribution valve switches to the F1 water circuit or the T1 water circuit, and sprays water in the third form through the third water spray channel connected to the F1 water circuit or sprays water in the first form through the first water spray channel connected to the T1 water circuit.

[0027] Compared with the prior art, the technical solution of the present invention and its beneficial effects are as follows:

[0028] (1) When the controller of the present invention adjusts the flow rate to the first flow rate level, the water inlet channel supplies water to the T2 water circuit and sprays water out from the second spray channel; when the controller adjusts the flow rate to the second flow rate level, the water inlet channel switches to supply water to the T1 water circuit and sprays water out through the first spray channel. Different flow rates correspond to different water outlet channels, which facilitates the separate control of water flow at different flow rate levels.

[0029] (2) The present invention selects the first function (buttock wash) or the second function (feminine wash), that is, selects the position of the spray nozzle; selects the first flow rate level or the second flow rate level, that is, selects the water pattern of the sprayed water. Based on the traditional method of two cleaning modes corresponding to two spray holes, it adds a control mode for the water pattern of different levels. No new spray holes are added, and no new buttons are added to the remote control, which makes the water outlet control system simple in structure and simultaneously meets multiple cleaning modes.

[0030] (3) The present invention achieves water pattern control for different gears and functions by using different water inlet methods for the water spray channels corresponding to each gear and function, thereby realizing the diversity of cleaning modes. Attached Figure Description

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. 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.

[0044] See Figures 1 to 9 A control method for a water outlet control system includes a controller, a switching unit 1, and a water spray body 2. The switching unit 1 includes an inlet channel 13, a T1 water path, and a T2 water path. The inlet channel 13 switches the water supply to the T1 water path and the T2 water path. The controller includes a first flow rate setting and a second flow rate setting for adjusting the flow rate of the inlet channel 13. The water spray body 2 has a first water spray channel 21 and a second water spray channel 22. The first water spray channel 21 is connected to the T1 water path, and the second water spray channel 22 is connected to the T2 water path.

[0045] When the controller adjusts the flow rate of the inlet channel 13 to the first flow rate setting, the inlet channel 13 supplies water to the T2 water circuit and sprays it out from the second spray channel 22; when the controller adjusts the flow rate of the inlet channel 13 to the second flow rate setting, the inlet channel 13 switches to supply water to the T1 water circuit and sprays it out through the first spray channel 21. Different flow rate settings correspond to different outlet channels, facilitating separate control of the water flow at different flow rate settings. It can be understood that the spray body also includes a first spray nozzle 24 that is connected to the first spray channel 21 and the second spray channel 22 respectively. That is, at the first flow rate setting, the water flow of the T2 water circuit flows through the second spray channel 22 and is sprayed out from the first spray nozzle 24; at the second flow rate setting, the water flow of the T1 water circuit flows through the first spray channel 21 and is sprayed out from the first spray nozzle 24.

[0046] In this embodiment, the first water spray channel 21 sprays columnar particulate water through the first water spray nozzle 24, and the second water spray channel 22 sprays dispersed particulate water through the first water spray nozzle 24. Specifically, the water inlet of the first water spray channel 21 is radially introduced along the rectifying cavity 23 of the water spray body, such as... Figure 7 The water flow, after being rectified by the rectifier column in the rectifier chamber 23, is ejected as columnar water particles from the first nozzle 24, such as... Figure 8 The second water spray channel 22 is designed to allow water to enter tangentially to the inner wall of the rectifier cavity or at a preset angle, such as... Figure 3 The water flow is accelerated and rotated in the rectifier chamber 23 before being ejected as dispersed particulate water through the nozzle, such as... Figure 4 This allows for the control of different water flow patterns at different flow rates.

[0047] The controller includes a first function key that can realize the first function and a second function key that can realize the second function. When the controller selects the first function and the first flow rate, the water inlet channel 13 is connected to the T2 water circuit. When the controller selects the first function and the second flow rate, the water inlet channel 13 is connected to the T1 water circuit. That is, the T1 water circuit and the T2 water circuit are the two water outlet circuits corresponding to the two flow rate levels of the first function (buttock wash).

[0048] The switching unit also includes water paths F1 and F2. The water inlet channel can switch the water supply to water paths F1 and F2. The spray body 2 has a third spray channel and a fourth spray channel. The third spray channel is connected to water path F1, and the fourth spray channel is connected to water path F2. When the controller selects the second function and the first flow rate setting, the water inlet channel is connected to water path F2; when the controller selects the second function and the second flow rate setting, the water inlet channel is connected to water path F1. That is, water paths F1 and F2 are the two water outlet channels corresponding to the two flow rate settings of the second function (feminine wash). In this embodiment, the spray body 2 also includes a second spray nozzle connected to the third spray channel and the fourth spray channel respectively. The third spray channel sprays water in a third form through the second spray nozzle, and the fourth spray channel sprays water in a fourth form through the second spray nozzle. In other embodiments, the first spray channel and the third spray channel can also use the same spray channel, and the second spray channel and the fourth spray channel can also use the same spray channel.

[0049] Selecting the first function (posterior wash) or the second function (feminine wash) selects the position of the water nozzle; selecting the first flow rate or the second flow rate selects the water pattern. Based on the traditional two washing modes corresponding to two water nozzles, a control mode for different water patterns at different levels has been added. No new water nozzles have been added, nor have any new buttons been added to the remote control.

[0050] In this embodiment, the switching unit further includes a primary water distribution valve 11 and a secondary water distribution valve 12. The primary water distribution valve 11 is connected to the inlet channel 13, the T1 water path, the F1 water path, and the Z1 water path, respectively. The inlet channel 13 is switched to be connected to the T1 water path, the F1 water path, and the Z1 water path through the primary water distribution valve 11. The secondary water distribution valve 12 is connected to the connecting channel 14, the T2 water path, and the F2 water path, respectively. The connecting channel 14 can be switched to be connected to the T2 water path and the F2 water path through the secondary switching valve 12; the Z1 water path is connected to the connecting channel 14.

[0051] When the first flow rate setting is selected, water flows through the inlet channel 13 into the primary water distribution valve 11. Simultaneously, the primary water distribution valve 11 switches to the Z1 water circuit, supplying water to the connecting channel 14 via the Z1 water circuit. Then, the secondary water distribution valve 12 switches to either the F2 water circuit or the T2 water circuit. Figure 2 The second type of water spray is emitted through the second spray channel 22 connected to the T2 water circuit, or the fourth type of water spray is emitted through the fourth spray channel connected to the F2 water circuit. Both the second and fourth types of water spray can be dispersed particulate water. When the second flow rate setting is selected, the water flows through the inlet channel 13 into the first-stage water distribution valve 11. Simultaneously, the first-stage water distribution valve 11 switches to either the T1 or F1 water circuit. Figure 6 The third form of water spray is emitted through the third water spray channel connected to the F1 water channel, or the first form of water spray is emitted through the first water spray channel 21 connected to the T1 water channel. The third form of water spray and the first form of water spray can be columnar particles of water.

[0052] The secondary water distribution valve is connected to the Z2 water circuit. The connection channel can be switched to the Z2 water circuit through the secondary water distribution valve. The Z2 water circuit is a self-cleaning water circuit for cleaning the sprayed water body.

[0053] The steps for the water outlet control system to execute the cleaning function at the first flow rate level are as follows:

[0054] S1, the initial position of the first-stage water distribution valve is connected to the Z1 water circuit, and the initial position of the second-stage water distribution valve is connected to the Z2 water circuit.

[0055] S2. When the first flow rate setting is selected by the remote control, the primary water distribution valve stays at the Z1 water outlet. When the first function is selected, the secondary water distribution valve switches to the T2 water outlet for cooling. When the second function is selected, the secondary water distribution valve switches to the F2 water outlet for cooling.

[0056] S3. After the cooling is completed, the secondary water distribution valve switches to the Z2 water circuit to perform self-cleaning of the spray nozzle's extension rod.

[0057] S4. After self-cleaning is completed, the secondary water distribution valve switches to the F2 water circuit or the T2 water circuit, and sprays out the fourth form of water spray through the fourth water spray channel connected to the F2 water circuit or sprays out the second form of water spray through the second water spray channel 22 connected to the T2 water circuit.

[0058] The steps for the water outlet control system to execute the cleaning function at the second flow rate level are as follows:

[0059] S1, the initial position of the first-stage water distribution valve is connected to the Z1 water circuit, and the initial position of the second-stage water distribution valve is connected to the Z2 water circuit.

[0060] S2. When the remote control selects the second flow rate setting, the secondary water distribution valve remains at the Z2 water outlet. When the first function is selected, the primary water distribution valve switches to the T1 water outlet for cooling. When the second function is selected, the primary water distribution valve switches to the F1 water outlet for cooling.

[0061] S3. After the cooling is completed, the first-stage water distribution valve switches to the Z1 water circuit to perform self-cleaning of the extension rod of the water spray body.

[0062] D4. After self-cleaning is completed, the first-level water distribution valve switches to the F1 water circuit or the T1 water circuit, and sprays water in the third form through the third water spray channel connected to the F1 water circuit or sprays water in the first form through the first water spray channel 21 connected to the T1 water circuit.

[0063] This embodiment can also be provided with a third flow rate setting. The cleaning steps of the third flow rate setting are the same as those of the second flow rate setting. The difference is that the intensity of the columnar water particles sprayed from the first spray channel is different due to the different water flow rate per unit time of the inlet channel 13.

[0064] The foregoing description illustrates and describes preferred embodiments of the present invention. It should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept by means of the foregoing teachings or techniques or knowledge in related fields.
