Description

Technical Field

[0001] This invention relates to the field of bathroom equipment technology, and more particularly to a toilet seat and toilet bowl. Background Technology

[0002] The vortex flushing method is a common flushing method for toilets.

[0003] The vortex flushing method has the following disadvantages. First, the existing flushing channels are all connected to the seat cavity. During flushing, some water enters the seat cavity, filling it. After flushing, the water inside the seat cavity flows back and out of the toilet bowl through the flushing outlet, resulting in wasted water. Second, because the flushing channels are connected to the seat cavity, pressure loss is easy, leading to a weakened flushing force at the flushing outlet, which in turn weakens the siphon and affects the flushing effect. Finally, because the flushing channels are connected to the seat cavity, the relatively large channel space allows more air to accumulate in the flushing water, causing splashing at the flushing outlet and affecting the user experience.

[0004] Therefore, there is an urgent need for a toilet seat and toilet device to solve the above problems. Summary of the Invention

[0005] According to one aspect of the present invention, the object is to provide a toilet body that can separate the wash ring flow channel and the seat cavity, improve the flushing effect and flushing efficiency of the toilet, and avoid splashing and waste of flushing water.

[0006] To achieve this objective, the present invention adopts the following technical solution: Toilet seat, including: The toilet bowl body has a toilet bowl space and a seat cavity formed within it, and a wash ring flow channel is formed circumferentially within the toilet bowl space. The water inlet structure is hollow, forming a water inlet channel. The water inlet channel is connected to the wash ring channel but is not connected to the seat cavity. Water in the water inlet structure can enter the wash ring channel to flush the toilet bowl space.

The transition section is connected to the water tank, and the water outlet extension section extends along the extension direction of the wash ring flow channel and connects to the wash ring flow channel.

[0008] As a preferred embodiment of the toilet body provided by the present invention, the cross-sectional area of ​​the water outlet of the water outlet extension section is smaller than the cross-sectional area of ​​the wash ring flow channel.

[0009] As a preferred embodiment of the toilet body provided by the present invention, the water outlet extension section includes a first water outlet channel and a second water outlet channel. The first water outlet channel and the second water outlet channel are respectively connected and disposed on opposite sides of the transition section. The opening direction of the first outlet channel is towards the extension direction of the wash ring channel, and the opening direction of the second outlet channel is towards the direction of the first water outlet channel.

[0010] As a preferred embodiment of the toilet body provided by the present invention, a first inlet is formed between the first water outlet channel and the transition section, and the ratio of the cross-sectional area of ​​the first outlet to the cross-sectional area of ​​the first inlet is 1.5-2.5; and / or, A second inlet is formed between the second outlet channel and the transition section, and the ratio of the cross-sectional area of ​​the second outlet to the cross-sectional area of ​​the second inlet is 1.5-2.5.

[0011] As a preferred embodiment of the toilet body provided by the present invention, a first inlet is formed between the first water outlet channel and the transition section, and a second inlet is formed between the second water outlet channel and the transition section, wherein the ratio of the cross-sectional area of ​​the second inlet to the cross-sectional area of ​​the first inlet is 1.2-2.

[0012] As a preferred embodiment of the toilet body provided by the present invention, in the vertical direction, the bottom height of the water outlet extension section is higher than the bottom height of the wash ring flow channel.

[0013] As a preferred embodiment of the toilet body provided by the present invention, the difference between the bottom height of the water outlet extension section and the bottom height of the wash ring flow channel is 2-5mm.

[0014] As a preferred embodiment of the toilet body provided by the present invention, the inner wall of the toilet body is provided with a guide ring platform along the circumference, the wash ring channel is formed above the guide ring platform, the guide ring platform forms a washing surface in the lower vertical direction, and the water in the wash ring channel can flow along the guide ring platform to the washing surface.

[0015] According to another aspect of the invention, the object is to provide a toilet seat comprising a toilet body as described in any of the above embodiments.

[0016] The beneficial effects of this invention are: The toilet bowl provided by this invention includes a toilet bowl body and a water inlet structure.

[0028] Embodiments of the present invention are described in detail below.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] Figure 1 This diagram illustrates a toilet seat provided in an embodiment of the present invention. Figure 2 A vertical sectional view of a toilet seat provided in an embodiment of the present invention is shown. (Refer to...) Figure 1 and Figure 2 This embodiment provides a toilet seat and a toilet bowl. The toilet bowl includes the toilet seat provided in this embodiment. In this embodiment, the toilet seat is specifically made of ceramic; in other embodiments, the toilet seat may be made of other materials.

[0030] The toilet includes a toilet bowl body 100 and a water inlet structure 200. The toilet bowl body 100 forms a non-communicating toilet bowl space 110 and a seat cavity 120. A washbasin flow channel 111 is formed circumferentially within the toilet bowl space 110. The water inlet structure 200 is hollow, forming a water inlet flow channel. This water inlet flow channel is connected to the washbasin flow channel 111 but is not connected to the seat cavity 120. Water from the water inlet structure 200 can enter the washbasin flow channel 111 to flush the toilet bowl space 110. By designing the water inlet structure 200 and the seat cavity 120 to be mutually unconnected, the washing channel 111 and the seat cavity 120 can be separated, avoiding the problem of water wastage and weakened flushing force caused by flushing water entering the large seat cavity 120, thus improving flushing efficiency and flushing effect. It can also avoid the problem of a large amount of gas mixed in the flushing water due to the large space of the seat cavity 120, thereby avoiding splashing of flushing water.

[0031] Specifically, the toilet also includes a water tank 300. The water inlet structure 200 includes a transition section 210 and a water outlet extension section that are interconnected. The transition section 210 is connected to the water tank 300, and the water outlet extension section extends along the extension direction of the washbasin flow channel 111 and connects to the washbasin flow channel 111. Water in the water tank 300 can sequentially enter the washbasin flow channel 111 through the transition section 210 and the water outlet extension section, thus flushing the toilet bowl space 110.

[0032] More specifically, in this embodiment, the cross-sectional area of ​​the outlet of the water outlet extension is smaller than the cross-sectional area of ​​the washing ring flow channel 111. This arrangement allows flushing water to flow from a smaller diameter into the larger cross-sectional area of ​​the washing ring flow channel 111, thereby increasing the impact force of the flushing water and thus improving the flushing effect and efficiency.

[0033] Figure 3 Show Figure 2 A magnified view of a section marked A in the middle; Figure 4 A transverse cross-sectional view of a toilet body provided in an embodiment of the present invention is shown. Figure 1 ; Figure 5 A transverse cross-sectional view of a toilet body provided in an embodiment of the present invention is shown. Figure 2 ; Figure 6 Show Figure 5 A magnified view of the structure marked B in the middle section. (Refer to...) Figures 4-6In this embodiment, the water outlet extension section includes a first water outlet channel 220 and a second water outlet channel 230. The first water outlet channel 220 and the second water outlet channel 230 are respectively connected and disposed on opposite sides of the transition section 210 in the width direction of the toilet seat. The opening direction of the first outlet 221 of the first water outlet channel 220 faces the extension direction of the washbasin channel 111 and is disposed towards the front of the toilet seat. The opening direction of the second outlet 231 of the second water outlet channel 230 is disposed along the width direction of the toilet seat and faces the direction of the first water outlet channel 220. That is, the second water outlet channel 230 is specifically as follows... Figure 4 and Figure 6 As shown, the flushing water, arranged in a C-shape, flows out of the second outlet 231 along a portion of the wash ring channel 111 located between the first outlet channel 220 and the second outlet channel 230, in the same swirling direction as the flushing water flowing out of the first outlet 221. With this arrangement, flushing water can enter the wash ring channel 111 simultaneously from two locations, resulting in higher flushing efficiency. Furthermore, in the swirling direction of the flushing water, the flushing water flowing out of the first outlet 221 performs a primary flushing of contaminants, while the flushing water flowing out of the second outlet 231 performs a secondary flushing, further enhancing the flushing effect.

[0034] Specifically, in the vertical direction, both the first water outlet channel 220 and the second water outlet channel 230 are located below the seat cavity 120, and the distance H1 between the upper end face of the first water outlet channel 220 and the upper end face of the second water outlet channel 230 and the lower end face of the seat cavity 120 is 30-70mm. Figure 7 As shown.

[0035] More specifically, the inner wall of the toilet bowl body 100 is provided with a flow guide ring platform 112 along the circumference. The wash ring channel 111 is formed above the flow guide ring platform 112, and the flow guide ring platform 112 forms a washing surface 113 in the lower vertical direction. Water in the wash ring channel 111 can flow along the flow guide ring platform 112 to the washing surface 113. It should be noted that the flow guide ring platform 112 and the washing surface 113 have a smooth arc transition to facilitate water guidance.

[0036] More specifically, at the rear end of the toilet seat in the front-rear direction, the portion of the flow guide ring 112 located between the first outlet 221 and the second outlet 231 constitutes a first flow guide step. The portions of the flow guide ring 112 corresponding to the front end in the front-rear direction and both sides in the width direction of the toilet seat constitute second flow guide steps. The ratio of the extension length of the second flow guide step to the extension length of the first flow guide step is preferably 2.5-4.

[0037] Furthermore, in the vertical direction, the bottom height of the water outlet extension is higher than the bottom height of the washing ring flow channel 111. That is, the bottom of both the first water outlet flow channel 220 and the second water outlet flow channel 230 is higher than the bottom of the washing ring flow channel 111. This arrangement facilitates the outflow of flushing water from the first water outlet flow channel 220 and the second water outlet flow channel 230.

[0038] Preferably, in this embodiment, the height difference H2 between the bottom of the first water outlet channel 220, the bottom of the second water outlet channel 230, and the bottom of the washing ring channel 111 is 2-5 mm. Figure 8 As shown.

[0039] Continue to refer to Figure 6 A first inlet 222 is formed between the first water outlet channel 220 and the transition section 210, and the ratio of the cross-sectional area of ​​the first outlet 221 to the cross-sectional area of ​​the first inlet 222 is 1.5-2.5. This arrangement shortens the time required for water to flow out of the first water outlet channel 220 and ensures a consistent flow rate of flushing water per unit time. Air inside the first water outlet channel 220 is easily carried away by the water flow, preventing a large pressure difference at the first outlet 221, effectively reducing noise at the first outlet 221, and improving the flushing effect.

[0040] Similarly, a second inlet 232 is formed between the second outlet channel 230 and the transition section 210, and the ratio of the cross-sectional area of ​​the second outlet 231 to the cross-sectional area of ​​the second inlet 232 is 1.5-2.5. Through this arrangement, the time required for water to flow out of the second outlet channel 230 can be shortened, and the volume of flushing water flowing out of the second outlet channel 230 per unit time can be guaranteed. Air inside the second outlet channel 230 can be smoothly carried away by the water flow, avoiding a large pressure difference at the second outlet 231, effectively reducing noise at the second outlet 231, and improving the flushing effect.

[0041] Continue to refer to Figure 6A first inlet 222 is formed between the first outlet channel 220 and the transition section 210, and a second inlet 232 is formed between the second outlet channel 230 and the transition section 210. The ratio of the cross-sectional area of ​​the second inlet 232 to the cross-sectional area of ​​the first inlet 222 is 1.2-2. Because the second outlet channel 230 has a C-shaped structure, the flushing water needs to circulate within it, therefore the flow resistance is slightly greater than the flow resistance of the flushing water in the first outlet channel 220. By setting the diameter of the second inlet 232 to be larger than the diameter of the first inlet 222, the amount of flushing water entering the second outlet channel 230 and the first outlet channel 220 from the transition section 210 can be balanced, and more water can enter the second outlet channel 230 from the transition section 210 per unit time, thus ensuring the water output effect of the second outlet channel 230.
