Description

Technical Field

[0001] This utility model relates to the field of toilets, and in particular to a toilet. Background Technology

[0002] Currently, toilets on the market have pipes that flush the inner wall of the toilet bowl. In order to improve the cleaning of dirt attached to the toilet bowl wall, the water pressure of the pipes that flush the inner wall of the toilet bowl needs to be very high. At present, the water pressure of the pipes is usually increased by installing a pressure booster in the toilet. However, the pressure booster greatly increases the cost of the toilet and is prone to damage. Utility Model Content

[0003] In view of the above problems, this utility model is proposed to provide a toilet that overcomes or at least partially solves the above problems. By setting a flush pipe with a gradually narrowing flushing channel, the flushing effect of the toilet is guaranteed.

[0004] Specifically, this utility model provides a toilet, comprising:

[0005] A base plate having a seat hole and a downwardly extending flange provided along the circumferential edge of the seat hole;

[0006] A toilet bowl, the toilet bowl defining a flushing chamber with an upward-facing first opening; a water inlet hole is provided on the peripheral wall of the toilet bowl; the upper edge of the toilet bowl abuts against the lower wall of the base plate, and the first opening is located on the outside of the flange;

[0007] An annular plate is disposed between the flange and the inner wall of the toilet bowl, and a plurality of first protrusions are provided along the outer circumferential side of the annular plate; the inner side wall of the annular plate is connected to the flange, and the first protrusions abut against the inner wall surface of the toilet bowl; a water outlet is defined between the base plate, the flange, the toilet bowl and the annular plate, and the water outlet communicates with the water inlet.

[0008] A flushing pipe defines a gradually narrowing flushing channel; the outlet of the flushing pipe is inserted into the inlet and communicates with the water channel; the flushing pipe is made of metal.

[0009] Optionally, the outer diameter of the flushing pipe gradually decreases along the direction of water flow.

[0010] Optionally, the height of the inlet of the flushing pipe is lower than the height of the outlet of the flushing pipe.

[0011] Optionally, one end of the flushing pipe is provided with an inclined surface, which faces the flange; a vertical plane extending laterally through the front end of the inclined surface is an auxiliary plane, the intersection line of the auxiliary plane and the flange is an auxiliary line, and the tangent line passing through any point of the auxiliary line is parallel to the inclined surface.

[0012] Optionally, the sidewall of the water inlet extends upward through the upper edge of the toilet bowl;

[0013] It also includes a rubber ring; the rubber ring is disposed between the upper edge of the toilet bowl and the lower wall of the base plate, the rubber ring abuts against the flushing pipe, and a sealant is provided between the flushing pipe and the water inlet.

[0014] Optionally, the toilet further includes:

[0015] A diversion pipe is provided, which defines a diversion cavity having an upward-facing second opening. The peripheral wall of the diversion cavity gradually narrows from top to bottom. A connecting pipe is provided on the diversion pipe. One end of the connecting pipe passes through the peripheral wall of the diversion cavity and communicates with the diversion cavity. The other end of the connecting pipe is connected to the inlet of the flushing pipe. The connecting pipe defines a gradually narrowing flow channel.

[0016] Optionally, the base plate also has a water outlet; the water outlet is located on the rear side of the seat hole;

[0017] The diversion pipe is installed on the lower wall of the base plate, and the second opening faces the water outlet.

[0018] Optionally, the toilet further includes a water tank; the water tank has a downward-facing third opening;

[0019] The upper wall of the base plate is also provided with an installation groove, the water outlet is located inside the installation groove, and the lower end of the water tank is inserted into the installation groove.

[0020] Optionally, the mounting groove is provided with sealant.

[0021] Optionally, the lower wall of the base plate is provided with a plurality of second protrusions, and the lower surface of the plurality of second protrusions is provided with positioning grooves;

[0022] The outer wall of the toilet bowl is provided with a plurality of third protrusions, and each third protrusion is inserted into a corresponding positioning groove.

[0023] In this invention, water flows along a gradually narrowing flushing channel in the flushing pipe, increasing water pressure. Water enters the channel defined by the base plate, flange, bowl, and annular plate through the inlet hole. It flows circumferentially within the channel and exits downwards through the gap between the outer wall of the annular plate and the inner wall of the bowl, defined by a first protrusion, flushing away dirt. The narrowing flushing channel provides a pressurizing effect, reducing cost compared to installing a pressurizing device inside the toilet, and making the flushing pipe less prone to damage and easy to replace even if damaged. Furthermore, the first protrusion abuts against the inner wall of the bowl, ensuring multiple uniformly wide gaps are formed between the outer wall of the annular plate and the inner wall of the bowl. In existing technology, the outer wall of the annular plate does not have a first protrusion; instead, it is spaced apart from the inner wall of the bowl, with water flowing out through these gaps. However, in actual installation, due to installation errors, gaps may appear between the outer wall of the annular plate and the inner wall of the toilet bowl, with one side wider than the other. This results in uneven water flow to and flushing of the inner wall of the toilet bowl, affecting the flushing effect on waste. The first protrusion ensures that multiple evenly wide gaps are formed between the outer wall of the annular plate and the inner wall of the toilet bowl, thus ensuring uniform water flow and further improving the flushing effect on waste.

[0038] Figure 1 This is a schematic structural diagram of a toilet according to one embodiment of the present utility model. Figure 1 As shown, and with reference Figures 2 to 8 This utility model embodiment provides a toilet 10, including a base plate 100, a bowl 300, an annular plate 400, and a flushing pipe 500. The base plate 100 has a seat hole 101, and a downwardly extending flange 110 is provided circumferentially along the edge of the seat hole 101. The bowl 300 defines a flushing chamber 302 with an upward-facing first opening 301. A water inlet hole is provided on the peripheral wall of the bowl 300. The upper edge of the bowl 300 abuts against the lower wall surface of the base plate 100, and the opening is located outside the flange 110. The annular plate 400 is disposed between the flange 110 and the inner wall of the bowl 300, and a plurality of first protrusions 410 are provided circumferentially along the outer side wall of the annular plate 400. The inner side wall of the annular plate 400 is connected to the lower edge of the flange 110, and the first protrusions 410 abut against the inner wall surface of the bowl 300. A water outlet channel 900 is defined between the base plate 100, the flange 110, the toilet bowl 300, and the annular plate 400, and the water outlet channel 900 communicates with the water inlet. A flushing pipe 500 defines a gradually narrowing flushing channel. The outlet of the flushing pipe 500 is inserted into the water inlet and communicates with the water outlet channel 900. The flushing pipe is made of metal.

[0039] The water flow within the flush pipe 500 flows along a gradually narrowing flush channel, increasing the water pressure. The water flowing through the flush pipe 500 enters the water channel 900 defined by the base plate 100, flange 110, toilet bowl 300, and annular plate 400 from the inlet hole. Within the water channel 900, the water flows circumferentially along the toilet bowl 300 and flows downwards through the gap between the outer wall of the annular plate defined by the first protrusion 410 and the inner wall of the toilet bowl 300, flushing the inner wall and removing dirt. The gradually narrowing flush channel provides a pressurizing effect, reducing the cost of the toilet 10 compared to installing a pressurizing device inside the toilet 10. Furthermore, the flush pipe 500 is less prone to damage and easy to replace even if damaged. Additionally, the contact between the first protrusion 410 and the inner wall of the toilet bowl 300 ensures that multiple uniformly wide gaps are formed between the outer wall of the annular plate 400 and the inner wall of the toilet bowl 300. In the prior art, the outer wall of the annular plate 400 does not have a first protrusion 410. The outer wall of the annular plate 400 is spaced apart from the inner wall of the toilet bowl, and water in the water channel 900 flows out through the gaps. However, in actual installation, due to installation errors, gaps may appear between the outer wall of the annular plate 400 and the inner wall of the toilet bowl 300, with one side being wider than the other. This results in uneven water flow towards and flushing the inner wall of the toilet bowl 300, affecting the flushing effect on waste. By setting the first protrusion 410, multiple gaps of uniform width can be formed between the outer wall of the annular plate 400 and the inner wall of the toilet bowl 300, thus ensuring uniform water flow and further improving the flushing effect on waste.

[0040] In some embodiments of this utility model, as shown in Figures 1 and 2, the outer diameter of the flushing pipe 500 gradually decreases along the water flow direction.

[0041] In some embodiments of this utility model, such as Figure 3 As shown, the height of the inlet of the flush pipe 500 is lower than the height of the outlet of the flush pipe 500. This arrangement can also increase the water pressure in the inlet pipe, which is beneficial to increasing the flushing effect of the water flow on the inner wall of the toilet bowl 300.

[0042] In some embodiments of this utility model, such as Figure 4 As shown, a slope 501 is provided at one end of the outlet of the flush pipe 500, with the slope 501 facing the flange 110. A vertical plane extending laterally through the front end of the slope 501 is an auxiliary plane, and the intersection of the auxiliary plane and the flange 110 is an auxiliary line. The tangent at any point on the auxiliary line is parallel to the slope 501. In other words, the fact that a portion of the outlet of the flush pipe 500 is the slope 501, and that the tangent at any point on the auxiliary line is parallel to the slope 501, ensures that when the water flows out of the outlet of the flush pipe 500, flows around the waterway 900, and returns to the outlet position of the flush pipe 500, the water flow will not be significantly obstructed, thus not affecting the flow.

[0043] In some embodiments of this utility model, such as Figure 4 As shown, the toilet 10 also includes a rubber ring 600. The sidewall of the water inlet extends upward through the upper edge of the bowl 300. The rubber ring 600 is positioned between the upper edge of the bowl 300 and the lower wall of the base plate 100, and it abuts against the flush pipe 500. A sealant is applied between the flush pipe 500 and the water inlet. The upper part of the flush pipe 500 abuts against the rubber ring 600, which seals the upper part of the flush pipe 500. Other areas where the flush pipe 500 inserts into the water inlet that require sealing are filled with sealant. The rubber ring 600 and the sealant work together to ensure that water does not leak between the flush pipe 500 and the water inlet during flushing, thus preventing leakage and ensuring a better user experience.

[0044] In some embodiments of this utility model, such as Figure 3 As shown, the toilet 10 also includes a diversion pipe 700. The diversion pipe 700 defines a diversion chamber with an upward-facing second opening, the peripheral wall of which tapers from top to bottom. A connecting pipe is provided on the diversion pipe 700, one end of which penetrates the peripheral wall of the diversion chamber and communicates with it, and the other end of which is connected to the inlet of the flush pipe 500. A portion of the water in the diversion pipe 700 enters the flush pipe 500 through the connecting pipe. The taper of the peripheral wall of the diversion chamber from top to bottom also helps to increase the drainage pressure and thus the pressure in the flush pipe 500.

[0045] Furthermore, in some embodiments of this invention, the connecting pipe defines a tapering flow channel. Similarly, the water flow within the connecting pipe along the tapering flow channel can increase the water pressure.

[0046] In some embodiments of this utility model, such as Figure 6 As shown, the base plate 100 also has a water outlet 102. The water outlet 102 is located behind the seat hole 101. The diverter pipe 700 is installed on the lower wall surface of the base plate 100, with its second opening facing the water outlet 102.

[0047] In some embodiments of this utility model, such as Figure 6 As shown, the toilet 10 also includes a water tank 200. The water tank 200 has a downward-facing third opening. An installation groove 103 is also provided on the upper surface of the base, and the lower end of the water tank 200 is inserted into the installation groove 103. The water tank 200 defines a water storage chamber, and the third opening communicates with the water storage chamber. Because the lower end of the water tank 200 is inserted into the installation groove 103, the water storage chamber also communicates with the second opening through a water outlet. When flushing is required on the inner wall of the toilet bowl 300, water flows from the water storage chamber through the water outlet 102 and the second opening into the diversion chamber of the diversion pipe. A portion of the water then flows through the connecting pipe into the flushing pipe 500, and then into the water channel 900, flowing downwards from the gap defined by the first protrusion 410 and the inner wall surface of the toilet bowl 300 to flush the inner wall.

[0048] In some embodiments of this utility model, such as Figure 4 As shown, sealant is provided in the mounting groove 103. To ensure the airtightness when the water tank 200 is connected to the base plate 100, sealant can be provided in the mounting groove 103, and then the lower end of the water tank 200 can be inserted into the mounting groove 103, which will ensure that the water tank 200 will not leak when it is installed on the base plate 100.

[0049] In some embodiments of this utility model, such as Figure 7 and Figure 8 As shown, the lower wall of the base plate 100 is provided with a plurality of second protrusions 120, and the lower surface of the plurality of second protrusions 120 is provided with positioning grooves 121. The outer wall of the toilet bowl 300 is provided with a plurality of third protrusions 310, and one third protrusion 310 is inserted into a corresponding positioning groove.

[0050] Inserting the third boss 310 into the positioning groove 121 on the second boss can ensure the accurate installation of the toilet bowl 300 and the base plate 100, and avoid significant installation errors between the toilet bowl 300 and the base plate 100, which would affect the size of the gap between the annular plate 400 and the inner wall of the toilet bowl 300.

[0051] In some embodiments of this utility model, the base plate 100, the flange 110, and the second boss are made of metal and are integrally formed. The toilet bowl 300 and the third boss are made of metal and are integrally formed. The annular plate 400 and the first boss are made of metal and are integrally formed.

[0052] The base plate 100, flange 110, toilet bowl 300 and ring plate 400 are made of metal, which can avoid the large amount of energy and ore consumed when the existing toilet 10 is made of ceramic. It is also conducive to resource recycling after scrapping. Moreover, if a certain part is damaged, the damaged part can be replaced.

[0053] In some embodiments of this utility model, as shown in the figure, the toilet 10 also includes a base shell 800, which is installed on the lower surface of the base plate 100 and defines an installation space, within which the toilet bowl is located.

[0054] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
