Toilet bowl and method of manufacture

Abstract

This application relates to the field of sanitary ware technology, providing a toilet and its processing method. The toilet includes a first shell and a second shell. The inner side of the first shell is configured to form a toilet bowl cavity for use. The second shell is spaced apart on the side of the first shell away from the toilet bowl cavity. Along the height direction of the toilet, the upper ends of the first shell and the upper ends of the second shell are connected, forming an inlet communicating with the toilet bowl cavity. The lower ends of the first shell and the lower ends of the second shell are connected, forming an outlet communicating with the toilet bowl cavity, thereby constructing a complete sewage discharge channel. The second shell is a one-piece molded continuous surface. This design not only improves the overall structural strength and sealing performance, but also effectively avoids the gas leakage problem caused by splicing gaps or glaze defects in traditional toilets. Furthermore, through the synergistic structure of the double shells and the design of the one-piece continuous surface, the long-standing problem of odor backflow in bathrooms can be solved.

Description

Technical Field

[0001] This application relates to the field of sanitary ware technology, and in particular to a toilet and its processing method. Background Technology

[0002] A toilet, also known as a ceramic toilet, flush toilet, or sit-down toilet, is a sanitary appliance characterized by its use in a sitting position.

[0003] In related technologies, toilets have the problem of odor leakage. Summary of the Invention

[0004] This application provides a toilet and a processing method that can solve the problem of odor escaping from the toilet.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] In a first aspect, this application provides a toilet, comprising:

[0007] The first housing, the inner side of which is constructed to form a urinal cavity;

[0008] The second housing is spaced apart from the first housing on the side away from the toilet bowl cavity. Along the height direction of the toilet, the upper end of the first housing and the upper end of the second housing are connected and enclosed to form an inlet communicating with the toilet bowl cavity. The lower end of the first housing and the lower end of the second housing are connected and enclosed to form an outlet communicating with the toilet bowl cavity.

[0009] The second shell is a continuous surface formed in one piece.

[0010] In some embodiments, the second housing includes:

[0011] The upper end of the first sub-shell is connected to the upper end of the first shell;

[0012] The second sub-shell has one end connected to the lower end of the first sub-shell and the other end connected to the lower end of the first shell.

[0013] In some embodiments, the second sub-housing includes:

[0014] The first surface, one end of which is connected to the lower end of the first sub-shell, extends along a direction perpendicular to the height of the toilet.

[0015] A second surface, one end of which is connected to the other end of the first surface;

[0016] The third surface has one end connected to the other end of the second surface, the other end of the third surface connected to the lower end of the second housing, and the third surface extends in a direction perpendicular to the height of the toilet.

[0017] Along the height direction of the toilet, the third surface is spaced above the first surface.

[0018] In some embodiments, the second and third surfaces together enclose and form a placement groove;

[0019] Toilets also include:

[0020] A sealing flange is installed in the placement groove. Along the height direction of the toilet, the upper surface of the sealing flange abuts against the third surface, and the lower surface of the sealing flange is coplanar with the first surface.

[0021] In some embodiments, the first housing and the second housing are integrally molded at 170°C to 190°C.

[0022] In some embodiments, the side of the second housing opposite to the first housing is coated with a coating;

[0023] And / or, the side of the first housing opposite to the second housing is coated with a coating.

[0024] In some implementations, it also includes:

[0025] A seal is provided on at least one of the first surface and / or the sealing flange.

[0026] Secondly, this application provides a processing method for a toilet seat, the processing method comprising the following steps:

[0027] The raw material is injected into the mold, and the mold temperature is controlled between 170°C and 190°C.

[0028] After the mold and raw materials are cooled to room temperature, they are demolded so that the raw materials solidify into a connected first shell and second shell.

[0029] The mold cavity is configured as a continuous surface.

[0030] In some embodiments, the raw materials include one or more of the following: calcium carbonate, wollastonite, resin, and additives.

[0031] In some implementations, the following steps are also included:

[0032] A coating is applied to the outer wall of the second housing;

[0033] And / or, install a seal on the bottom wall of the second housing.

[0034] This toilet structure, by setting a first shell to form a toilet bowl cavity, and by setting a second shell to connect with the first shell to protect the first shell and also to form the outer surface of the toilet, improves the overall aesthetics of the toilet while increasing the rigidity of the first shell. By positioning the second shell at a distance from the first shell away from the toilet bowl cavity, a hollow cavity is formed between the first and second shells, reducing the weight of the toilet and the amount of material used in its manufacturing while maintaining overall strength. By sequentially connecting the inlet, toilet bowl cavity, and outlet, the toilet is easy for the user to use. By making the second shell a one-piece continuous surface, the number of openings in the second shell is reduced, preventing odors from entering the gap between the first and second shells through the holes in the second shell and further diffusing to the outside of the toilet, thus reducing odor escape.

[0035] Therefore, the toilet provided in the embodiments of this application can solve the problem of odor escaping from the toilet. Attached Figure Description

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0044] In existing technology, traditional ceramic toilets are made by sintering at high temperatures of 1250℃ and above. Due to process requirements, in order to prevent the internal parts of the toilet from cracking during sintering, two bottom vents are required so that the gas pressure during sintering can be released to the outside of the toilet. After sintering, the two vents can be left open or sealed with adhesive. As the usage time increases, the adhesive will corrode and detach, causing odor to enter the internal cavity of the toilet through the vents and then escape to the outside of the toilet.

[0045] To overcome the shortcomings of existing technologies, a first shell is provided to form the toilet bowl cavity. A second shell is provided to connect with the first shell to protect it and also to form the outer surface of the toilet, making the toilet more aesthetically pleasing and increasing the rigidity of the first shell. By positioning the second shell at a distance from the first shell away from the toilet bowl cavity, a hollow cavity is formed between the first and second shells. This reduces the weight of the toilet and the amount of material used in its manufacturing process while maintaining its overall strength. By sequentially connecting the inlet, toilet bowl cavity, and outlet, the toilet is easier for users to use. By making the second shell a one-piece continuous surface, openings in the second shell are reduced, preventing odors from entering the gap between the first and second shells through the openings and then spreading to the outside of the toilet, thus reducing odor escape.

[0046] Therefore, the toilet provided in the embodiments of this application can solve the problem of odor escaping from the toilet.

[0047] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0048] like Figure 1As shown, this application embodiment provides a toilet, including: a first housing 100 and a second housing 200. The inner side of the first housing 100 is configured to form a toilet bowl cavity 101. The second housing 200 is spaced apart on the side of the first housing 100 away from the toilet bowl cavity 101. Along the height direction of the toilet, the upper end of the first housing 100 and the upper end of the second housing 200 are connected and enclosed to form an inlet 102 communicating with the toilet bowl cavity 101. The lower end of the first housing 100 and the lower end of the second housing 200 are connected and enclosed to form an outlet 103 communicating with the toilet bowl cavity 101. The second housing 200 is an integrally formed continuous surface.

[0049] The following sections provide a detailed description of the specific structure of the toilet and its manufacturing process, as well as various possible implementation methods.

[0050] It should be noted that the second housing 200 is a continuous surface formed in one piece, meaning that the second housing 200 does not have holes, gaps, or other cross-sectional structures. This is not a limitation and can be selected according to actual usage requirements.

[0051] It should be noted that the inlet 102, the urinal cavity 101, and the outlet 103 are connected in sequence.

[0052] It should be noted that outlet 103 is sealed to drain pipe 10.

[0053] The second housing 200 provided in the embodiments of this application includes: a first sub-housing 201 and a second sub-housing 202. The upper end of the first sub-housing 201 is connected to the upper end of the first housing 100, one end of the second sub-housing 202 is connected to the lower end of the first sub-housing 201, and the other end of the second sub-housing 202 is connected to the lower end of the first housing 100.

[0054] It is understood that, through the above-described embodiments, the first sub-shell 201 can form the outer wall surface of the toilet, and the second sub-shell 202 can form the base of the toilet.

[0055] It should be noted that the first sub-shell 201 extends along the height direction of the toilet.

[0056] It is understood that, through the above-described embodiments, the first sub-shell 201 can form the outer peripheral wall of the toilet, thereby protecting the first shell 100, and can also form the outer surface of the toilet to improve its aesthetics.

[0057] The second sub-shell 202 provided in the embodiments of this application includes: a first surface 2021, a second surface 2022 and a third surface 2023. One end of the first surface 2021 is connected to the lower end of the first sub-shell 201 and extends along a direction perpendicular to the height of the toilet. One end of the second surface 2022 is connected to the other end of the first surface 2021. One end of the third surface 2023 is connected to the other end of the second surface 2022 and the other end of the third surface 2023 is connected to the lower end of the second shell 200 and extends along a direction perpendicular to the height of the toilet. Along the height of the toilet, the third surface 2023 is spaced above the first surface 2021.

[0058] It is understood that, through the above implementation method, the first surface 2021 can be placed in a preset position and abut against the surface to be placed so that the toilet can be placed stably. By setting the second surface 2022, it can be connected to the first surface 2021 and the third surface 2023 respectively. By setting the third surface 2023, it can cooperate with the second surface 2022 to form an installation space so that the toilet can be installed in the preset position.

[0059] The second surface 2022 and the third surface 2023 provided in the embodiments of this application jointly enclose the placement groove to form a placement groove. The toilet also includes a sealing flange 300, which is disposed in the placement groove. Along the height direction of the toilet, the upper surface of the sealing flange 300 abuts against the third surface 2023, and the lower surface of the sealing flange 300 is coplanar with the first surface 2021.

[0060] Understandably, by setting the sealing flange 300, the toilet outlet 103 can be sealed and connected to the opening of the pre-positioned drain pipe 10, further reducing the escape of toilet odors. In addition, the upper surface of the sealing flange 300 abuts against the third surface 2023, and the lower surface of the sealing flange 300 is coplanar with the first surface 2021, which can also reduce the formation of a cantilever structure in the toilet, preventing instability and thus extending the toilet's lifespan.

[0061] It should be noted that a through channel is provided in the middle of the sealing flange 300. One end of the through channel is connected to the outlet 103, and the other end of the through channel is connected to the drain pipe 10.

[0062] It should be noted that the outer peripheral wall of the sealing flange 300 can abut against the second surface 2022, or the outer peripheral wall of the sealing flange 300 can be spaced apart from the second surface 2022 along the height direction intersecting the toilet. There are no restrictions here, and the choice can be made according to actual usage requirements.

[0063] It should be noted that the angle between the intersection of the height direction of the toilet and the height direction of the toilet can be any value between 0 degrees and 180 degrees, and there is no restriction. It can be selected according to actual usage needs.

[0064] It should be noted that the second surface 2022 and the third surface 2023 are intersecting. The angle between the second surface 2022 and the third surface 2023 can be any value between 0 degrees and 180 degrees. There is no restriction here, and it can be selected according to the actual use requirements.

[0065] It is understood that, through the above implementation method, the second surface 2022 and the third surface 2023 can be connected.

[0066] In one embodiment, the second surface 2022 and the third surface 2023 are arranged perpendicularly, and the outer peripheral wall of the sealing flange 300 abuts against the second surface 2022.

[0067] It is understood that through the above-described embodiments, the second surface 2022 and the third surface 2023 can be connected, and the contact area between the sealing flange 300 and the second sub-housing 202 can be increased to improve the connection strength between the sealing flange 300 and the second sub-housing 202. In addition, the contact area between the second surface 2022 and the third surface 2023 and the preset position can be increased, thereby avoiding the second surface 2022 and the third surface 2023 from being suspended, which would lead to local stress concentration and thus extend the service life of the toilet.

[0068] The first housing 100 and the second housing 200 provided in the embodiments of this application are integrally formed at 170°C to 190°C.

[0069] It is understood that, through the above-described embodiments, the gas pressure generated inside the first shell 100 and the second shell 200 during the firing process of the toilet can be reduced, preventing the toilet from cracking, deforming, or even exploding. Furthermore, it can avoid the decomposition reaction of calcium carbonate and wollastonite during heating, thus preventing the release of gases and reducing the rapid expansion of these gases at high temperatures, thereby improving the yield rate of the toilet. In addition, the above-described embodiments can also reduce the energy consumption in the processing of the toilet.

[0070] In one embodiment, the first housing 100 and the second housing 200 are integrally formed at 180°C.

[0071] It is understood that, through the above-described embodiments, the rapid increase in gas pressure generated inside the first shell 100 and the second shell 200 during the firing process of the toilet can be reduced, thus preventing the toilet from cracking, deforming, or even exploding. Furthermore, it can prevent the decomposition reaction of calcium carbonate and wollastonite during heating, which would release gas, thereby reducing the rapid expansion of this gas at high temperatures and improving the yield rate of the toilet. In addition, the above-described embodiments can also reduce the energy consumption in the processing of the toilet.

[0072] The second housing 200 provided in the embodiments of this application is coated with a coating on the side opposite to the first housing 100, and / or the first housing 100 is coated with a coating on the side opposite to the second housing 200.

[0073] It is understandable that when the second housing 200 is coated on the side opposite to the first housing 100, the coating can form a smooth and dense protective layer on the surface of the toilet, thereby extending the service life of the toilet and improving its aesthetics. When the first housing 100 is coated on the side opposite to the second housing 200, the coating can form a smooth and dense protective layer on the wall of the toilet bowl cavity 101, thereby extending the service life of the toilet and facilitating the cleaning of the toilet bowl cavity 101.

[0074] It should be noted that the coating can be: a superhydrophobic coating, a nano coating, a glaze, or other coatings that improve the hardness of the outer wall of the toilet. There are no restrictions here, and the coating can be selected according to the actual use needs.

[0075] The toilet provided in the embodiments of this application further includes: a seal, the seal being disposed on at least one of the first surface 2021 and / or the sealing flange 300.

[0076] It is understandable that by setting a seal, the first surface 2021 and / or the sealing flange 300 can be sealed to the preset position, thereby improving the connection strength between the first surface 2021 and / or the sealing flange 300 and the preset position. It can also reduce the occurrence of odors in the drain pipe 10 escaping to the outside of the toilet through the gap between the first surface 2021 and the preset position, and / or reduce the occurrence of odors in the drain pipe 10 escaping to the outside of the toilet through the gap between the sealing flange 300 and the preset position.

[0077] It should be noted that seals can be installed in various positions. Examples of the installation positions of seals will be given below.

[0078] In one embodiment, the seal is disposed on the first surface 2021.

[0079] It is understood that, through the above-described embodiments, the first surface 2021 and the preset position can be sealed together, thereby improving the connection strength between the first surface 2021 and the preset position, and also reducing the occurrence of odors in the drain pipe 10 escaping to the outside of the toilet through the gap between the first surface 2021 and the preset position.

[0080] In one embodiment, the seal is located on the sealing flange 300.

[0081] It is understood that through the above-described embodiments, the sealing flange 300 and the preset position can be sealed together, thereby improving the connection strength between the sealing flange 300 and the preset position. It can also reduce the occurrence of odors in the drain pipe 10 escaping to the outside of the toilet through the gap between the sealing flange 300 and the preset position.

[0082] In one embodiment, seals are respectively provided on the first surface 2021 and the sealing flange 300.

[0083] It is understood that, through the above-described embodiments, a sealed connection can be achieved between the first surface 2021 and the preset position, thereby improving the connection strength between the first surface 2021 and the preset position. This also reduces the occurrence of odors from the drain pipe 10 escaping to the outside of the toilet through the gap between the first surface 2021 and the preset position. Furthermore, a sealed connection can be achieved between the sealing flange 300 and the preset position, thereby improving the connection strength between the sealing flange 300 and the preset position, and further reducing the occurrence of odors from the drain pipe 10 escaping to the outside of the toilet through the gap between the sealing flange 300 and the preset position.

[0084] Understandably, there are no restrictions on the specific installation location of the seals; they can be selected based on actual usage requirements.

[0085] It should be noted that the sealing element can be a wax sealing ring, a rigid plastic flange, or other components that can serve a sealing connection. There are no restrictions on the type of sealing element, and it can be selected according to the actual usage requirements.

[0086] In one embodiment, the seal is a wax sealing ring.

[0087] It is understood that, through the above-described embodiments, the wax sealing ring can be installed between the bottom of the toilet and the preset position, and the bottom of the toilet and the preset position can be sealed together to improve the service life of the toilet. It can also reduce the occurrence of odor from the drain pipe 10 escaping to the outside of the toilet through the gap between the bottom of the toilet and the preset position.

[0088] The embodiments of this application provide a processing method applied to the toilet provided in any of the above embodiments. The processing method includes the following steps:

[0089] S01: Inject the raw material into the mold and control the mold temperature between 170℃ and 190℃.

[0090] S02: After cooling the mold and raw materials to room temperature, demold the mold so that the raw materials solidify into the connected first shell 100 and second shell 200;

[0091] The mold cavity is configured as a continuous surface.

[0092] It is understood that, through the above-described embodiments, the increase in gas pressure inside the first housing 100 and the second housing 200 during the toilet manufacturing process, caused by rising temperature, can be reduced, thus preventing the toilet from cracking, deforming, or even exploding. Furthermore, it avoids the decomposition reaction of calcium carbonate and wollastonite in the raw materials during heating, preventing the release of gases and reducing the rapid expansion of these gases at high temperatures, thereby improving the yield rate of the toilet. Since the processing method of this application does not generate drastic gas pressure expansion, there is no need to create vents in the second housing 200, allowing the first housing 100 and the second housing 200 to be integrally formed continuous surfaces, thereby reducing the escape of odors to the outside of the toilet. In addition, the above-described embodiments can also reduce processing energy consumption during the toilet manufacturing process.

[0093] It should be noted that the injection pressure of the raw material injection module is 70 bar to 110 bar.

[0094] It is understandable that the above-described implementation method can reduce the formation of air bubbles in the mold when the raw material is injected into the mold, allow the raw material to quickly fill every corner of the mold, and ensure that the raw material fits tightly into the mold cavity, thereby improving the mechanical strength of the toilet.

[0095] In one embodiment, the injection pressure of the raw material into the mold is 100 bar.

[0096] It is understandable that the above-described implementation method can reduce the formation of air bubbles in the mold when the raw material is injected into the mold, allow the raw material to quickly fill every corner of the mold, and ensure that the raw material fits tightly into the mold cavity, thereby improving the mechanical strength of the toilet.

[0097] It should be noted that the raw materials include one or more of the following: calcium carbonate, wollastonite, resin, and additives.

[0098] Understandably, by incorporating calcium carbonate and wollastonite, the rigidity, hardness, and scratch resistance of the finished toilet can be improved. By incorporating resin, calcium carbonate and wollastonite can be encapsulated and bonded together. After the resin cures, a continuous three-dimensional mesh structure can be formed, encapsulating the calcium carbonate and wollastonite within it, thus providing the toilet with strength, toughness, and shape. Furthermore, the resin possesses corrosion resistance, stain resistance, and yellowing resistance, which can extend the service life of the toilet. By incorporating additives, the resin can be cured, or the first shell 100 and the second shell 200 can be easily removed from the mold. In addition, it can also be used to adjust or enhance the color, impact resistance, and other properties of the toilet.

[0099] It should be noted that the resin can be unsaturated polyester resin, acrylic resin, urea-formaldehyde resin, engineering plastic, or other types of resin. There are no restrictions, and the resin can be selected according to the actual application requirements.

[0100] It should be noted that the additives may be curing agents, initiators, accelerators, release agents, pigments, toughening agents, stabilizers, ultraviolet absorbers, or combinations of the above. There are no restrictions here, and they can be selected according to actual usage requirements.
