Description

Technical Field

[0001] The present application relates to a toilet seat, in particular to a toilet seat with a wash ring flow channel. The present application also relates to a toilet having the above toilet seat. Background Art

[0002] The wash ring flow channel is typically located at the top of the toilet seat and releases water through a wash ring outlet on the inner wall of the toilet seat, achieving flushing of the inner wall of the toilet seat. Typically, a certain amount of water pressure is required within the wash ring flow channel so that the wash ring water sprayed from the wash ring outlet will surround the inner wall of the toilet seat and flush it, achieving a good flushing effect.

[0003] However, if the ring washing flow channel and the ring washing outlet are not set properly, it may cause the ring washing water to splash, which not only affects the user experience, but also causes hygiene problems.

[0004] Application Contents

[0005] In view of the above problems, the present application discloses a toilet seat that can prevent the splashing of wash water.

[0006] The present application also discloses a toilet having the toilet seat.

[0007] In order to achieve the above objectives, this application adopts the following technical solutions:

[0008] The present application provides a toilet seat having a wash ring flow channel formed within the top interior of the toilet seat. The wash ring flow channel has a water outlet formed on the inner wall of the toilet seat. The wash ring flow channel further has a flow-blocking cavity formed at one end of the water outlet for water to flow into. The flow-blocking cavity is arranged side by side with the water outlet so that water flowing back from the flow-blocking cavity can exert lateral pressure on the water flowing out of the water outlet.

[0009] By adjusting the relative positions of the choke chamber and the water outlet in the wash channel, the wash water can be directed in one direction, preventing splashing. Furthermore, the clever design of the choke chamber ensures a sufficient flow rate for optimal wash results.

[0010] In an exemplary embodiment of the toilet seat, the flow blocking cavity is located above the water outlet in the height direction. The above structure can effectively prevent the toilet water from splashing upward.

[0011] In one exemplary embodiment of the toilet seat, the main flow cavity's extension length L1 along the wash ring flow path and its width W perpendicular to the wash ring flow path are set to: 20 mm ≤ L1 ≤ 60 mm, and 20 mm ≤ W ≤ 40 mm. With these dimensions, the flow-blocking cavity effectively controls the wash ring water flowing out of the outlet.

[0012] In an exemplary embodiment of the toilet seat, the ratio P of the cross-sectional area of ​​the wash ring flow channel to the cross-sectional area of ​​the water outlet is set to: 1.5≤P≤3. Under this size, the flow rate of the wash ring water flowing out of the water outlet can be better controlled.

[0013] In one exemplary embodiment of a toilet seat, the seat is made of ceramic. A structural cavity, formed during the ceramic manufacturing process, is located at the top of the seat. The wash ring flow channel is isolated from the structural cavity. This design prevents air within the structural cavity from affecting the flow of water through the wash ring flow channel, maintaining a relatively stable water pressure within the flow channel and a relatively stable flow of water out of the outlet. This also prevents prolonged water flow.

[0014] In one exemplary embodiment of a toilet seat, the top portion of the toilet seat has a structural protrusion protruding toward the inside of the toilet bowl. The structural protrusion surrounds the top of the toilet seat, and the distance h between the water outlet and the structural protrusion is set to h ≥ 10 mm. This distance ensures that water flowing out of the water outlet is blocked by the structural protrusion and does not splash.

[0015] In an exemplary embodiment of the toilet seat, the water outlet is formed by a water outlet pipe, and the extension length L2 of the water outlet pipe is set to: 10mm≤L2≤50mm. This structure provides the water outlet with a guide section in the water outlet direction, making the water flow less likely to disperse and splash.

[0016] The present application also provides a toilet comprising the above-mentioned toilet seat. The toilet seat can effectively prevent splashing of wash water. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] To make the purpose, technical solutions, and advantages of this application more clear, the following will provide a clear and complete description of the technical solutions of this application in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0037] In this document, “illustrative” means “serving as an example, instance or illustration”, and any diagram or implementation described in this document as “illustrative” should not be interpreted as a more preferred or more advantageous technical solution.

[0038] To simplify the drawings, only the parts related to the present application are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically shown or labeled.

[0039] The following describes in detail the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.

[0040] Figure 1 A structural diagram for illustrating an exemplary embodiment of a toilet seat. Figure 2 yes Figure 1 Schematic diagram of the cross-sectional structure in the II cutting direction. Figure 1 and Figure 2 As shown, a wash ring flow channel 122 is formed inside the top end 12 of the toilet seat 10 , and the wash ring flow channel 122 has a water outlet 124 opened on the inner wall of the toilet seat 10 .

[0041] Figure 2 This is a cross-sectional view, so the wash ring flow channel 122 is not a closed structure. Those skilled in the art will understand that the wash ring flow channel 122 is located within the top end 12 of the toilet seat 10. Except for the water inlet and outlet ends, the water supply structure within the toilet seat 10 is closed (e.g., in the form of a pipe). During actual use, a certain amount of water pressure is maintained within the wash ring flow channel 122, causing the wash ring water ejected from the water outlet 124 to surround the inner wall of the toilet seat 10 and flush it.

[0042] Currently, toilet seats on the market are generally made of ceramic and are ceramic bodies. Therefore, during the ceramic molding process, the wash ring flow channel 122 can be directly molded inside the ceramic body through a mold. Of course, depending on different design requirements, the wash ring flow channel 122 can also be set in other forms.

[0043] like Figure 2 As shown, the wash ring flow channel 122 is provided with a water outlet 124 at its water outlet end, and a flow blocking cavity 123 for water flow to flow into. Figure 2 In the cross-sectional structural diagram shown, the flow blocking cavity 123 is not a closed structure, but in the actual structure, the flow blocking cavity 123 is also a closed structure formed inside the top end 12 of the toilet seat 10.

[0044] See also Figure 3 , Figure 3 A partial cross-sectional view of the toilet seat at the outlet end is provided. Figure 2 and Figure 3 As shown, the flow-blocking chamber 123 and the water outlet 124 are arranged side by side at the water outlet end of the wash ring channel 122. After adopting this structure, during the water outlet process, pressure can be applied to the water flow out of the water outlet 124 from the side to control the direction of the water flow out of the water outlet 124.

[0045] See Figure 3 , Figure 3 The arrows in the figure represent the direction of water flow, which schematically illustrates the effect of the flow blocking cavity 123 on the direction of water flow out of the water outlet 124. Figure 3As shown, the water flow in the wash ring flow channel 122 can be schematically divided into two water flows (actually the same water flow) after reaching the water outlet: one is the A1 water flow flowing directly to the water outlet 124, and the other is the A2 water flow flowing directly to the flow blocking chamber 123. Because the flow blocking chamber is closed, the water flow flowing into the flow blocking chamber 123 under pressure will continuously form a reverse water flow B. This reverse water flow B will continuously interact with the subsequent A2 water flow to form a side water flow C that rushes towards the A1 water flow from the side, providing pressure to the A1 water flow from the side. When the A1 water flow flows through the water outlet 124, it will be affected by the pressure of the above-mentioned side water flow C, changing its original outflow direction and deviating as a whole to the direction of the side water flow C, forming the wash ring water flow D.

[0046] It can be understood that by presetting the positional relationship between the flow blocking cavity 123 and the water outlet 124, the outlet direction of the wash water flow D flowing out of the water outlet 124 can be controlled to prevent the wash water flow D from splashing uncontrollably. Figure 2 In the illustrated embodiment, the flow blocking chamber 123 is positioned above the water outlet 124 in the height direction, effectively preventing the rim-washing water flow D from splashing upward. Those skilled in the art will appreciate that, depending on design requirements, the relative positional relationship between the flow blocking chamber 123 and the water outlet 124 may vary. For example, the flow blocking chamber 123 may completely surround or partially surround the water outlet 124, or the flow blocking chamber 123 may be positioned away from the inner wall of the toilet seat relative to the water outlet 124. This design directs the water flow toward the inner wall of the toilet seat, thereby achieving a better rim-washing effect.

[0047] It should also be noted that after the wash water flows out of the outlet 124, its flow needs to have a certain flow rate to achieve the wash action, so the flow rate of the water A1 to the wash water flow D cannot be affected too much by the side water flow C. This application takes this technical problem into consideration. Figure 3 As shown, after the water flow A2 flows into the flow-blocking chamber 123, the first step of deceleration is achieved to form a reverse water flow B. The reverse water flow B meets the subsequent A2 water flow and is further decelerated to form a side water flow C. The flow rate of the side water flow C is relatively low, so the pressure it applies to the A2 water flow from the side will not be too large, and will not affect the initial flow rate of the A2 water flow too much. The flow rate of the finally formed circle-washing water flow D can fully ensure the circle-washing action and achieve a better circle-washing effect.

[0048] Figure 4 yes Figure 3 The structural diagram of the T direction is shown in FIG. Figure 4Two dimensions of the flow-blocking cavity 123 can be displayed, namely the extension length L1 along the extension direction of the ring-washing flow channel 122 and the width W perpendicular to the extension direction of the ring-washing flow channel 122. In one embodiment, the extension length L1 and the width W can be set to: 20mm≤L1≤60mm, 20mm≤W≤40mm. Under this dimension, the flow-blocking cavity 123 has a better control effect on the ring-washing water flow flowing out of the outlet 124.

[0049] In one embodiment, the ratio P between the cross-sectional area of ​​the wash ring flow channel 122 and the cross-sectional area of ​​the water outlet 124 is set to: 1.5≤P≤3. Under this size, the flow rate of the wash ring water flowing out of the water outlet 124 can be better controlled.

[0050] As mentioned above, the toilet seat can be made of ceramic. The top of the ceramic toilet seat needs to be installed with a toilet ring and other structures. In order to smoothly produce this structural shape, the top of the ceramic toilet seat is usually made using a single-sided slurry process. The mold used in the single-sided slurry process only has an external wall layer and no internal core mold. During grouting, the cavity is directly poured. The flowing grout adheres to the surface of the wall mold in the cavity and gradually solidifies. After a certain period of time, the slurry needs to be drained before the mold is removed. Because the single-sided slurry mold has no internal core module, only the slurry on the wall mold side solidifies in the cavity, and the slurry in the center will still be in a molten state. After the internal slurry is drained, a structural cavity will be formed. Please refer to Figure 2 The structural cavity 125 in the.

[0051] exist Figure 2 In the illustrated embodiment, the wash ring flow channel 122 is isolated from the structural cavity 125, that is, the wash ring flow channel 122 and the structural cavity 125 are not interconnected. With this design, the gas in the structural cavity 125 will not affect the water outlet of the wash ring flow channel 122, so that the water flow pressure in the wash ring flow channel 122 can be maintained relatively stable, and the wash ring water flow out of the water outlet 124 is relatively stable. In addition, if the wash ring flow channel 122 and the structural cavity 125 are interconnected, the wash ring water will enter the structural cavity 125, prolonging the drainage time. After the control of the wash ring flushing is completed, the liquid in the structural cavity 125 will gradually flow out of the water outlet 124, giving people the feeling of water leakage and a poor user experience.

[0052] exist Figure 2 and Figure 3 In the illustrated embodiment, the water outlet 124 is formed by a water outlet pipe, and the extended length L2 of the water outlet pipe is set to: 10mm≤L2≤50mm. This structure gives the water outlet 124 a certain thickness in the water outlet direction, forming a guiding section to prevent the water flow from being dispersed and splashing.

[0053] Figure 5 yes Figure 1 Schematic diagram of the cross-sectional structure in the Ⅱ-Ⅱ cutting direction, Figure 5 In the illustrated embodiment, the top portion 12 of the toilet seat 10 has a structural protrusion 122 protruding toward the interior of the toilet bowl. This protrusion 122 surrounds the entire top portion 12 of the toilet seat 10, increasing the support surface area of ​​the top surface of the toilet seat 10 and blocking water flow within the toilet seat 10. In one embodiment, the distance h between the water outlet 124 of the wash ring flow channel 122 and the structural protrusion 122 is ≥ 10 mm. This distance ensures that water flowing out of the water outlet 124 is blocked by the structural protrusion 122 and does not splash.

[0054] The present application also provides a toilet having the above toilet seat 10, such as Figure 1 As shown, the toilet seat 10 can effectively prevent the splashing of toilet wash water.

Based on the above teachings of the present application, those skilled in the art may make other improvements or modifications based on the above embodiments. Those skilled in the art should understand that the above description is only a better explanation of the purpose of the present application, and the scope of protection of the present application shall be based on the scope of protection of the claims.
