Description

Technical Field

[0001] The utility model belongs to the technical field of intelligent toilets, and particularly relates to a heating and water distribution device for an intelligent toilet. Background Art

[0002] Intelligent toilets on the market are generally divided into three types. One is an intelligent toilet with functions such as cleaning, heating, and sterilization. Another is an intelligent toilet with an automatic seat cover replacement function. The other is an intelligent toilet seat with an automatic seat cover replacement and cleaning function. Existing intelligent toilets have grouped designs for structures such as pressure reducing valves, electrolyzed water components, vacuum breakers, water heaters, and water distribution devices, and are connected through pipes. The number of required spare parts is large, the mold opening cost is high, and the overall manufacturing cost is high.

[0003] For highly integrated designs, integrating different functional components means that the connection relationships and positional relationships between the components need to be redesigned, rather than simply splicing and combining the functional components of other products. Specifically in the heating and water distribution device, for the heater, pressure reducing valve, and water distribution device, each component not only needs to meet the integration between functions but also the compactness requirements of the integrated structure. At the same time, the water circuit needs to be simplified, the water circuit route optimized, the number of component assemblies reduced, and the safety of the device considered. Therefore, a systematic optimization design of each component is required; and the existing heating and water distribution device is prone to cause siphon phenomenon, thus damaging the water distribution device.

[0040] Refer to Figures 1-9 As shown, a heating and water distribution device for a smart toilet includes:

[0041] An installation shell 1, with a semi-circular heating pipe 11 provided at the edge of the installation shell 1, a heating inlet 111 and a heating outlet 112 provided at the end surface. An inlet and outlet water tank 12 is provided on the inner side surface between the heating pipes 11. A water distribution tank hole 121 is provided at the nearly arc-shaped end of the inlet and outlet water tank 12, and a pressure stabilizing hole 122 is provided at the other end. A pressure stabilizing groove 13 is provided on the outer side surface of the installation shell 1 corresponding to the pressure stabilizing hole 122. A water inlet pipe 14 is provided to communicate between the pressure stabilizing groove 13 and the heating inlet 111. A water outlet pipe 15 is provided to communicate between the heating outlet 112 and the water distribution tank hole 121. Temperature control groove holes 16 are respectively provided on the inner side surfaces of the pipelines on both sides of the heating pipe 11. A temperature sensing hole 17 is provided on the installation shell 1 corresponding to the water outlet pipe 15 or the water distribution tank hole 121;

[0042] And a pressure stabilizing valve 2 provided in the pressure stabilizing groove 13, with a pressure stabilizing cover 21 fixed to the installation shell 1. A water distribution switch 3 is provided in the water distribution tank hole 121. A heating wire 4 is provided in the heating pipe 11. A temperature controller 5 is provided in the temperature control groove hole 16. A temperature sensor 6 is provided in the temperature sensing hole 17;

[0043] And an upper cover 7 that matches and covers the installation shell 1. The upper cover 7 is provided with a matching water inlet hole 71 and a water outlet hole 72 corresponding to the water distribution switch 3; and an end cover 8 that covers the end surface of the installation shell 1. The installation shell 1 and the end cover 8 form a water inlet cavity 81 at the heating inlet 111 and a water outlet cavity 82 at the heating outlet 112, and the water inlet cavity 81 and the water outlet cavity 82 are isolated from each other;

[0044] A first vacuum breaker 811 is provided inside the water inlet chamber 81. The first vacuum breaker 811 is provided with a first limit cage 812 and a first sealing bead 813. The first limit cage 812 is provided inside the end cover 8 opposite to the water inlet pipe 14, and the first sealing bead 813 is provided inside the first limit cage 812 and located at the port of the water inlet pipe 14. The first vacuum breaker 811 is horizontally arranged.

[0045] The pressure stabilizing valve 2, the water distribution switch 3, the heating wire 4, the temperature controller 5, and the temperature sensor 6 are integrated on the mounting shell 1, and the mounting shell 1 is hermetically assembled by using the upper cover 7, the end cover 8, and the pressure stabilizing cover 21. The mounting shell 1 is in a "D" shape, forming a "U"-shaped heating pipe 11 around the edge of the "D"-shaped mounting shell 1, so that the heating wire 4 forms a heating length as long as possible in the mounting shell 1. The water flow is fully heated in the "U"-shaped heating pipe 11, reducing the power of the heating wire 4 and the manufacturing and use costs. Moreover, a heating inlet 111 and a heating outlet 112 are formed on the mounting end face of the flat end of the "D"-shaped mounting shell 1, facilitating the installation and connection of the heating wire 4 to the terminal post, and enabling the inlet and outlet of the water flow to be concentrated in the middle of the "U"-shaped heating pipe 11 through the water inlet pipe 14 and the water outlet pipe 15, making the device more compact. The design of the outer shell 9 of the mounting shell 1, the upper cover 7, the end cover 8, and the pressure stabilizing cover 21 has fewer components, and each component is convenient for mold opening and has a low cost.

[0046] The inlet and outlet water tank 12 is arranged in the middle of the "U"-shaped heating pipe 11. The water distribution tank holes 121 and the pressure stabilizing holes 122 are arranged at both ends of the inlet and outlet water tank 12. The water inlet pipe 14 and the water outlet pipe 15 are respectively arranged on both sides of the water distribution tank holes 121 and the pressure stabilizing holes 122, forming an inlet and outlet water circuit with a compact structure design.

[0047] The water inlet chamber 81 and the water outlet chamber 82 are formed inside the end cover 8, or on the end face of the mounting shell 1, or jointly formed by both. If the water inlet chamber 81 and the water outlet chamber 82 are formed on the end face of the mounting shell 1, the end cover 8 can be a flat cover plate.

[0048] The pressure stabilizing valve 2 adjusts the flow rate of the medium by controlling the opening of the opening and closing member in the valve body, reduces the pressure of the medium, and at the same time adjusts the opening of the opening and closing member with the action of the pressure behind the valve, so that the pressure behind the valve is maintained within a certain range. Under the condition that the inlet pressure changes continuously, the outlet pressure is maintained within the set range to protect the subsequent living and production appliances.

[0049] Using the heating wire 4 as the heating device not only has low cost and is convenient for installation, but also directly contacts the water, with small heating internal energy. After the heating wire 4 generates heat, it directly heats the water, with high heating efficiency and faster temperature control. Since the present application uses the heating wire 4 and it directly passes through water, it is easy to cause the water to be electrified. Therefore, the present application specifically sets the water inlet pipe 14 and the water outlet pipe 15 as the electric shock protection walls before and after the "U"-shaped heating pipe 1111.

[0050] When a vacuum is formed at the upstream end of the water inlet pipe 14, it will cause the water at the downstream end to flow back, impacting the upstream pipeline and device, preventing the water flow from guiding at the spray bar end, avoiding damage to the internal structure, and protecting the spray bar structure. By setting the first vacuum breaker 811 to block the nozzle of the water inlet pipe 14, it acts as a check valve, and the first vacuum breaker 811 is equivalent to a one-way valve.

[0051] Furthermore, a second vacuum breaker 821 is provided in the water outlet chamber 82. The second vacuum breaker 821 is provided with an air inlet hole 822, a sealing groove 823, a second limiting cage 824, and a second sealing bead 825. The air inlet hole 822 is provided on the end cover 8 between the heating outlet 112 and the water outlet pipe 15. The sealing groove 823 is provided inside the air inlet hole 822. The second limiting cage 824 is provided at the opening of the sealing groove 823. The second sealing bead 825 is provided in the second limiting cage 824 inside the sealing groove 823; the diameter of the second sealing bead 825 is larger than the diameter of the air inlet hole 822 and smaller than the diameter of the second limiting cage 824.

[0052] When the heating water distribution device is working, under the action of water pressure, the second sealing bead 825 is pushed into the air inlet hole 822 by the water flow, thereby sealing the air inlet hole 822 to avoid the water flow from flowing out of the air inlet hole 822; when there is no water flow working, under the action of gravity, the second sealing bead 825 drops into the sealing groove 823 to open the air inlet hole 822. In the case where the first vacuum breaker 811 is damaged, due to the backflow air pressure generated in the pipeline, the second sealing bead 825 disengages from the air inlet hole 822, enabling the inside of the heating water distribution device to communicate with the atmosphere, avoiding the generation of vacuum negative pressure, preventing the water flow from guiding at the spray bar end, avoiding damage to the internal structure, and protecting the spray bar structure. A pipeline is provided at the outer end of the air inlet hole 822 to be connected to the toilet to prevent water from overflowing when discharging water.

[0053] Furthermore, a push rod 826 is provided on the installation shell 1 opposite to the sealing groove 823. The push rod 826 restricts the second sealing bead 825 within the second limiting cage 824; the first sealing bead 813 and the second sealing bead 825 are glass beads or steel beads.

[0054] This push rod 826 can reduce the setting area of the second limiting cage 824.

[0055] Furthermore, the installation shell 1, the upper cover 7, and the end cover 8 form an outer shell 9. The outer periphery of the outer shell 9 is provided with screw plates 91 at intervals along the height of the heating pipe 11 at the heating inlet 111, and the screw plates 91 are provided with U-shaped openings.

[0056] Specifically, the screw plates 91 are respectively arranged perpendicular to the planes of the installation shell 1, the upper cover 7 and the bottom surface of the end cover 8; the screw plates 91 can be respectively arranged on the outer side surface of the installation shell 1, the top end of the upper cover 7 (the side away from the end cover 8), both side surfaces in the thickness direction of the end cover 8 or the bottom surface of the end cover 8.

[0057] By arranging the screw plates 91, the device can be adaptively assembled with an existing toilet, facilitating the direct assembly and application of the device to the existing toilet and reducing the transformation cost.

[0058] Further, screw holes 92 are provided on the thickness side surface of the heating inlet 111 of the outer shell 9. The screw holes 92 are parallel to the thickness direction. Right-angle plates 93 are provided in the screw holes 92. Screw grooves 94 are respectively provided on the two plate surfaces of the right-angle plates 93; the screw grooves 94 on the two plate surfaces of the right-angle plates 93 are perpendicular to each other.

[0059] Since the specifications of toilets are various and the positions of the screw holes are also set differently, in order to further match different existing toilets, the screw holes 92 and the right-angle plates 93 are added for adaptive installation, and strip-shaped screw grooves 94 are provided on the right-angle plates 93 to adapt to the installation screw holes at different positions.

[0060] Further, an air injection hole 18 is provided on the inner side surface of the installation shell 1 and is communicated with the water outlet pipe 15. An air injection pipe 181 is provided in the air injection hole 18, and the air injection pipe 181 penetrates through the upper cover 7.

[0061] Adding an air injection connection hole facilitates directly injecting gas into the device, supplementing bubbles into the water, making the flushing more comfortable, increasing the device functions and improving the use effect. Liquid medicine can also be supplemented through the air injection hole 18.

[0062] Further, an adjustment hole 22 is provided on the pressure stabilizing cover 21. An adjustment screw 23 is provided in the adjustment hole 22. The adjustment screw 23 is threadedly connected with the adjustment hole 22. The inner end of the adjustment screw 23 abuts against the spring of the pressure stabilizing valve 2.

[0063] By adding the adjustment screw 23 structure to the pressure stabilizing valve 2 and rotating the adjustment screw 23 with a screwdriver, the pressure of the spring of the pressure stabilizing valve 2 can be adjusted, thereby realizing the adjustment of the water pressure and meeting the requirements of using different inlet water pressures and forming different outlet water pressures.

[0064] Further, the installation shell 1 is in a "D" shape or a square shape, and correspondingly, the heating pipe 11 is in a "U" shape or a "concave" shape; a pipe groove 113 is provided at the section of the heating pipe 11 far from the end face, and a groove convex 73 corresponding to the pipe groove 113 is provided on the upper cover 7.

[0065] The "U"-shaped or "concave"-shaped heating pipe 11 forms a semi-circular structure at the edge of the "D"-shaped or square installation shell 1, and the semi-circular structure forms the inlet and outlet end faces of the heating pipe 11 on the other side.

[0066] The arc section of the "U"-shaped heating pipe 11 or the horizontal section connecting the two side pipelines adopts a pipe groove 113 to expose the heating wire 4, so as to facilitate the assembly of the heating wire 4 into the "U"-shaped heating pipe 11. It can extend and install from both ends of the pipe groove 113, or extend from one end and then be assisted to penetrate to the other end through the pipe groove 113 part. And the heating wire 4 can be pressed tightly by the groove protrusion 73 on the upper cover 7 to prevent the heating wire 4 from moving under the action of water flow. Since the pipe groove 113 forms a certain angle with the two side heating pipes 11, it is not conducive to mold opening and demolding. The setting of the pipe groove 113 facilitates mold opening and forming, and reduces the mold opening and manufacturing costs.

[0067] Furthermore, a first grounding hole 74 is provided between the voltage stabilizing hole 122 and the water distribution tank hole 121 on the upper cover 7, a second grounding hole 19 is provided at the end of the water outlet pipe 15 near the water distribution tank hole 121, and a first grounding post and a second grounding post are respectively arranged in the first grounding hole 74 and the second grounding hole 19; the temperature sensing hole 17 is arranged at the water outlet of the water distribution tank hole 121 of the water outlet pipe 15.

[0068] Furthermore, the first grounding post is installed through the first grounding hole 74 from the inner side of the upper cover 7, the second grounding post is installed through the second grounding hole 19 from the outer side of the installation shell 1, and the temperature sensor 6 is installed through the temperature sensing hole 17 from the outer side of the installation shell 1; the voltage stabilizing cover 21 is provided with an extension plate 24 extending to the second grounding post and the temperature sensor 6, the outer end of the second grounding post abuts against the extension plate 24, and a temperature sensing clip 25 is provided at the front end of the extension plate 24; the temperature sensor 6 is arranged inside the temperature sensing clip 25 at the outer end; a reinforcing plate 26 extending to the extension plate 24 is provided at the center of the outer side of the voltage stabilizing cover 21; a water passing hole 741 is provided at the front ends of the first grounding post and the second grounding post.

[0069] The grounding is separately arranged at the water inlet and outlet ends to achieve grounding at both ends, better protecting the equipment and personal safety. The temperature sensor 6 is arranged at the water outlet of the water outlet pipe 15, closer to the water outlet, and the temperature detection is more accurate. At the same time, the temperature sensor 6 is relatively far from the strong electricity of the heating wire 4, avoiding damage to the temperature sensor 66.

[0070] Due to the positional relationship, the second grounding post and the temperature sensor 6 need to be inserted into the water outlet pipe 15 and the water distribution tank hole 121 from the outer side of the installation shell 1, so it is necessary to set the extension plate 24 and the temperature sensing clip 25 for fixation. The setting of the reinforcing plate 26 can strengthen the strength of the temperature sensing clip 25 and can extend the installation space of the pressure stabilizing valve 2 outwards, reducing the internal installation space.

[0071] The front end of the grounding post is designed with a water through hole 741. Water flows through the copper hole, which has a better grounding effect.

[0072] In some embodiments, a boss is provided at the outer end of the water distribution tank hole 121. The boss is circumferentially provided with water seepage grooves, and the water distribution motor is arranged on the boss.

[0073] The water seepage grooves can drain the water seeping out of the water distribution tank hole 121 to avoid entering the water distribution motor and causing damage.

[0074] In some embodiments, the water distribution switch 3 is provided with a water distribution static plate, a water distribution moving plate, a linkage plate and a water distribution motor. The water distribution static plate, the water distribution moving plate and the linkage plate are sequentially stacked in the water distribution tank hole 121. The water distribution static plate is clamped in the water distribution tank hole 121. The central part of the water distribution static plate is provided with an inlet hole and a drain hole which are oppositely distributed. The drain hole is provided with a first drain groove extending to the side at the end far from the water distribution moving plate, and a second drain groove at the end near the water distribution moving plate. A third drain groove corresponding to the second drain groove is provided on the side of the water distribution moving plate near the water distribution static plate. When the third drain groove is communicated with the inlet hole and the third drain groove at the same time, water inlet is realized; the outer circle of the inlet hole and the drain hole of the water distribution static plate are spaced with water distribution holes. A water distribution notch is provided on the side of the water distribution moving plate. The water distribution notch is sequentially communicated with the water distribution holes through the rotation of the water distribution moving plate; the inlet hole is communicated with the water inlet hole 71, the water distribution holes are correspondingly communicated with the water outlet holes 72, and the first drain groove is communicated with the voltage stabilizing hole 122; the linkage plate is clamped with the water distribution moving plate, and the water distribution motor is fixed on the outside of the installation shell 1 and inserted and fixed with the linkage plate.

[0075] In this application, the switching valve and the water distribution valve are integrated into the water distribution switch 3. The opening and closing of the water circuit and the water distribution are synchronously realized through the water distribution motor, reducing the number of valve bodies set, making the device more compact and reducing costs.

[0076] In some embodiments, the water distribution static plate and the water distribution moving plate are ceramic plates; the second drain groove and the third drain groove are crescent-shaped, arc-shaped or fan-shaped; a water distribution tank is correspondingly provided on the side of the water distribution hole near the water distribution moving plate. The water distribution tank is square, circular, arc-shaped or fan-shaped, and the opening size of the arc-shaped water distribution tank is gradually changed along the circumferential direction.

[0077] Using ceramic plates as the water distribution static plate and the water distribution moving plate improves the control accuracy, avoids water leakage, and increases the number of switching times to 500,000 times, improving the service life of the equipment.

[0078] The water distribution tanks can be designed in the same shape or different shapes. The opening size of the arc-shaped water distribution tank is gradually changed along the circumferential direction, so as to control the water flow. When the water distribution notch coincides with the small end of the arc-shaped water distribution tank, the water flow is small. The closer to the large opening end, the larger the water flow, realizing the control of the flow rate.

[0079] In some embodiments, the thermostat 5 on the side of the water inlet chamber 81 is a manually reset thermostat 51, and the thermostat 5 on the side of the water outlet chamber 82 is a self-resetting thermostat 52; a positive terminal and a negative terminal penetrating the mounting shell 1 are respectively provided at the water inlet chamber 81 and the water outlet chamber 82, and the manually reset thermostat 51, the positive terminal, the heating wire 4, the negative terminal and the self-resetting thermostat 52 are connected in series in sequence.

[0080] The design of the dual thermostat 5 is adopted to achieve safer control. A manually reset thermostat 51 is arranged on the side of the water inlet chamber 81, and a self-resetting thermostat 52 is arranged on the side of the water outlet chamber 82 to achieve better temperature control. The self-resetting thermostat 52 is arranged at the water outlet to accurately control the water outlet temperature and avoid too high water outlet temperature. The manually reset thermostat 51 is to ensure power-off in case the self-resetting thermostat 52 fails. When the temperature at the water inlet is too high, it indicates that the temperature has got out of control and cutting off the power is necessary. The overall design is more reasonable.

[0081] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
