Description

Technical Field

[0001] This invention belongs to the technical field of bathroom products, specifically relating to a concealed pre-embedded box assembly. Background Technology

[0002] Existing concealed shower systems typically have two inlet and two outlet water outlet assemblies: a cold water inlet, a hot water inlet, and outlets for connecting a handheld shower head and an overhead shower head. If additional outlets are needed, the appropriate assembly model must be selected during the installation of the pre-installed assemblies. Once installed, it is difficult to change the number of outlets or add additional outlets to enhance the functionality of the shower system.

[0003] However, as consumers' demands for bathroom shower systems have increased, more and more functional water outlet devices have been designed, making the drawbacks of existing pre-embedded boxes increasingly apparent. Because it requires knocking down already renovated walls and re-embedding and laying pipes, it greatly limits consumers' ability to upgrade and creates obstacles to enhancing their experience. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art and provide a concealed pre-installed box assembly, so that after the pre-installed box assembly is installed, it can meet the needs of consumers to add water outlets at any time without changing the already installed pre-installed box assembly. To achieve the above objective, this invention adopts the following technical solution:

[0005] A concealed pre-embedded box assembly includes: a box body, the box body including a bottom plate and a wall plate, the wall plate being disposed on the bottom plate and forming a box cavity; a pre-embedded core, disposed within the box cavity to connect an inlet pipe and an outlet pipe; the box cavity including a bypass clearance groove, the bypass clearance groove being disposed on the side of the pre-embedded core to accommodate an additional bypass outlet pipe.

[0006] Preferably, the bypass clearance groove is formed by the sidewalls of the wall panel, the bottom plate, and the embedded core.

[0007] Preferably, the pre-embedded core is provided with a water-passing valve seat, a water inlet channel, and a water outlet channel; the pre-embedded core is connected to the water inlet pipe through the water inlet channel and to the water outlet pipe through the water outlet channel; the water-passing valve seat is located on the top surface of the pre-embedded core and is provided with a water inlet that connects to the water inlet channel and a water outlet that connects to the water outlet channel.

[0008] Preferably, the water inlet and / or water outlet includes a heat-fused outer tube and a positioning inner tube; the positioning inner tube is disposed inside the heat-fused outer tube to form a connecting annular groove between the positioning inner tube and the heat-fused outer tube; the water inlet pipe or water outlet pipe is connected to the water inlet and / or water outlet through the connecting annular groove.

[0009] Preferably, the wall panel is provided with a plurality of pipe holes, each of the pipe holes being provided with a corresponding water inlet and water outlet, and the water inlet and water outlet extending to the outside of the box body through the pipe holes.

[0010] Preferably, the water inlet includes a cold water channel and a hot water channel; the water outlet includes a first water outlet and a second water outlet; the water inlet includes a cold water inlet connected to the cold water channel, a hot water inlet connected to the hot water channel, a first water outlet connected to the first water outlet, and a second water outlet connected to the second water outlet.

[0011] Preferably, the pre-embedded core includes a water-passing component and a housing that encapsulates the water-passing component; the positioning inner tube, water inlet, and water outlet are disposed on the water-passing component, and the water-passing valve seat is disposed on the housing.

[0012] Preferably, the positioning inner tube is provided with a heat-fusion section to form a double-layer heat-fusion sealed connection with the water inlet pipe or water outlet pipe through the positioning inner tube and the heat-fusion outer tube.

[0013] Preferably, the embedded core is made of hot-melt plastic or metal material.

[0014] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) By adopting the technical solution of the present invention, a bypass clearance groove is added in the box cavity of the pre-embedded box group and on one side of the pre-embedded core. When the water valve body is adapted to the pre-embedded core, a space is reserved for the water valve body to extend to the side to provide a bypass water outlet for accommodating the added bypass water outlet pipe. Thus, there is no need to change the pre-embedded box group or the pre-embedded core. Only by adapting the water valve body with different bypass water outlets, a water outlet can be added without dismantling the wall and re-laying the pre-embedded box group.

[0016] (2) The bypass clearance groove is formed by the side walls of the wall panel, the bottom plate, and the embedded core. It has a simple structure and can...

[0017] It provides more space to accommodate the bypass outlet pipe, making installation easier, and can be adapted regardless of whether the water valve body has a bypass outlet pipe or not;

[0018] (3) A water valve seat is installed in the pre-embedded core to fit the water valve body, which facilitates the connection between the pre-embedded box assembly and the water valve.

[0019] Modular installation of the body simplifies the adaptation and installation process and facilitates maintenance;

[0020] (4) The inlet and outlet channels are designed with a structure including a heat-fused outer pipe and a positioning inner pipe, utilizing the positioning inner pipe...

[0021] The pipe is positioned to fix the hot-melt water pipe to the outside, so that the hot-melt part of the water pipe and the hot-melt outer pipe are fixed in a specific position. Therefore, during the insertion and installation of the water inlet and outlet with the external water pipe, it is not necessary to determine the docking position of the hot-melt part. This enables the hot-melt part to be quickly positioned, reduces the difficulty of operation, and ensures the yield of the finished product after hot-melt.

[0022] (5) The wall panel is provided with pipe holes corresponding to the water inlet and water outlet. The water inlet and water outlet of the pre-embedded core extend to the outside of the box through the corresponding pipe holes, which facilitates the sealing connection between the water inlet pipe and the water outlet pipe and the water inlet and water outlet, without the need to disassemble the pre-embedded box assembly, which facilitates the pre-embedding operation of the water pipe and the pre-embedded box assembly.

[0023] (6) The pre-embedded core adopts a split structure including water-passing components and a shell, and the water-passing components are used to form a water-passing pipe.

[0024] The housing is used to enclose the water inlet and provide a fixed support for the water inlet. The water inlet can be made of metal, such as copper pipe, which is more conducive to the cleaning of water pipes. The housing is easy to injection mold, which makes it easy to make the water inlet valve seat, reducing manufacturing costs and simplifying the manufacturing process.

[0025] (7) Both the inner positioning pipe and the outer heat-fusion pipe are equipped with heat-fusion sections, and the inlet and outlet water channels of the pre-embedded box assembly are heat-fused.

[0026] When the inlet and outlet pipes are fused together, the positioning inner pipe and the heat-fused outer pipe simultaneously form a heat-fused seal connection with the inlet and outlet pipes, achieving a double-layer heat-fused seal effect. This improves the reliability of the heat-fused seal between water pipe fittings and further enhances the sealing reliability of the water pipes in the concealed shower system.

[0027] (8) The embedded core is integrally formed by hot melt plastic injection molding, which can simplify the production process and improve production efficiency;

[0028] (9) The embedded core is made of metal, which makes it easy to connect the metal inlet and outlet pipes, improving the overall reliability and cleanliness of the shower system's water circuit. Attached Figure Description

[0049] Example 1.

[0050] Please see Figures 1 to 3 This embodiment provides a concealed pre-embedded box assembly, including a box body 1 and a pre-embedded core 2. The box body 1 includes a base plate 11 and a wall plate 12. The wall plate 12 is fixedly connected to the base plate 11 and together with the base plate 11 forms a box cavity. The pre-embedded core 2 is disposed in the box cavity and is fixedly installed with the box body 1.

[0051] The pre-embedded core 2 has a water-passing valve seat 25 on the side away from the base plate 11. The water-passing valve seat 25 forms a planar structure to fit the water-passing valve body connected to it, which facilitates the modular installation of the pre-embedded box assembly and the water-passing valve body, simplifies the adaptation and installation process, and facilitates maintenance.

[0052] In this embodiment, the pre-embedded core 2 is integrally injection molded from hot melt plastic, and the inlet and outlet channels are directly formed by injection molding. The inlet channel includes a cold water channel 21 for connecting to an external cold water pipe and a hot water channel 22 for connecting to an external hot water pipe; the outlet channel includes a first outlet channel 23 and a second outlet channel 24 for connecting to an external outlet pipe, so as to realize the connection of two water outlets from the pre-embedded box assembly.

[0053] The water valve seat 25 is provided with an inlet and an outlet, which are connected to the inlet channel and the outlet channel, respectively. Specifically, the inlet includes a cold water inlet 251 for connecting to the cold water channel 21 and a hot water inlet 252 for connecting to the hot water channel 22; the outlet includes a first outlet 253 for connecting to the first outlet channel 23 and a second outlet 254 for connecting to the second outlet channel 24.

[0054] In this embodiment, the box cavity includes a bypass clearance groove, which is located on the side of the embedded core 2 and is formed by the wall panel 12, the bottom plate 11 and the side wall of the embedded core 2, and is used to accommodate the added bypass water outlet pipe.

[0055] On the wall panel 12, pipe holes 121 are provided at the corresponding positions of cold water channel 21, hot water channel 22, first water outlet channel 23 and second water outlet channel 24. On the embedded core 2 of this embodiment, the cold water channel 21, hot water channel 22, first water outlet channel 23 and second water outlet channel 24 used to connect the external water inlet pipe and water outlet pipe all extend to the outside of the box 1 through the corresponding pipe holes 121.

[0056] This embodiment of the concealed pre-installed box assembly is used as one of the pre-installed components of a concealed shower system, and is adapted to the water valve body. During shower installation, the entire assembly is embedded in the wall. The external water inlet pipe connects to the cold water channel 21 and hot water channel 22 outside the box 1, and connects to the outlet pipes of the overhead shower head and hand shower head. The first outlet channel 23 and the second outlet channel 24 are also connected outside the box 1. When the pre-installed box assembly is adapted to connect to the water valve body, the cold water inlet 251 and hot water inlet 252 connect to the water inlet of the water valve body, guiding cold and hot water into the water valve body. The first outlet 253 and the second outlet 254 connect to the outlet of the water valve body, guiding the mixed water into the outlet pipes respectively.

[0057] The pre-embedded box assembly of this embodiment, due to the addition of a bypass clearance groove on one side of the pre-embedded core 2 within the box cavity, provides space for the bypass water outlet to extend laterally when the water valve body is fitted and installed with the pre-embedded core 2. This space accommodates the added bypass water outlet pipe, thus eliminating the need to change the pre-embedded box assembly or the pre-embedded core 2. Only water valve bodies with different bypass water outlets need to be fitted, allowing for the addition of a water outlet without dismantling the wall or re-laying the pre-embedded box assembly. Because the bypass clearance groove is located within the box cavity, it can be fitted regardless of whether the water valve body has a bypass water outlet pipe.

[0058] like Figure 4 As shown, in other embodiments, the embedded core 2 can be formed of metal materials, such as stainless steel or copper. Especially when the inlet pipe and outlet pipe are also made of stainless steel or copper, it is convenient to weld the inlet pipe and outlet pipe to the embedded core 2, making the connection between the water circuit components of the overall shower system more reliable.

[0059] Example 2.

[0060] The difference between the concealed pre-embedded box assembly in this embodiment and Embodiment 1 lies only in the composition of the pre-embedded core 2. For example... Figures 5 to 8 As shown, in the pre-embedded box assembly of this embodiment, the pre-embedded core 2 includes a water-passing component 4 and a housing 5. The water-passing component 4 is made of metal material, and the housing 5 is used to encapsulate and wrap the water-passing component 4, and is integrally injection molded.

[0061] In this embodiment, the cold water channel 21, hot water channel 22, first water outlet channel 23, and second water outlet channel 24 each include a heat-fused outer tube 26 and a positioning inner tube 27. The heat-fused outer tube 26 is mounted on the housing 5, allowing it to be integrally formed during the manufacturing of the housing 5. The positioning inner tube 27 is mounted on the water-passing component 4. After the housing 5 encapsulates the water-passing component 4, the positioning inner tube 27 is positioned inside the heat-fused outer tube 26, forming a connecting annular groove 28 between the positioning inner tube 27 and the heat-fused outer tube 26. The inlet and outlet pipes are connected to the cold water channel 21, hot water channel 22, first water outlet channel 23, and second water outlet channel 24 via the connecting annular groove 28, and are heat-fused with the heat-fused outer tube 26 to achieve a sealed connection between the inlet and outlet pipes and the embedded core 2. In this embodiment, the positioning inner tube 27 is used to position the external hot-melt water pipe, so as to limit the hot-melt part of the water pipe and the hot-melt outer tube 26 to a specific position. Therefore, during the insertion and installation of the water inlet and outlet with the external water pipe, it is not necessary to determine the docking position of the hot-melt part, thereby enabling the hot-melt part to be quickly positioned, reducing the difficulty of operation, and ensuring the yield of the finished product after hot-melt.

[0062] In other embodiments, the positioning inner tube 27 may also be provided with a heat-fusion part, so that the positioning inner tube 27 and the heat-fusion outer tube 26 can form an effective heat-fusion seal connection with the inner and outer pipe walls of the inlet or outlet pipe, respectively, achieving a double-layer heat-fusion seal effect, improving the reliability of the heat-fusion seal between water pipe fittings, and further enhancing the sealing reliability of the water pipes in the concealed shower system.

[0063] In this embodiment, the embedded core 2 adopts a split structure including a water-passing component 4 and a housing 5. The water-passing component 4 forms a water-passing pipe and a water outlet, and the housing 5 is used to encapsulate the water-passing component 4 and provide fixed support for it. The water-passing component 4 can be made of metal, such as copper pipe, which is more conducive to the cleaning of the water in the pipe. The housing 5 is easy to manufacture by injection molding, which facilitates the production of the water-passing valve seat 25, reduces manufacturing costs, and simplifies the manufacturing process. It should be understood that in other embodiments, the cold water channel 21, hot water channel 22, first water outlet channel 23, and second water outlet channel 24 may not have a positioning inner pipe 27, and the above-mentioned technical effects can still be achieved.

[0064] The descriptions of the foregoing specification and embodiments are used to explain the scope of protection of the present invention, but do not constitute a limitation on the scope of protection of the present invention. Modifications, equivalent substitutions, or other improvements to the embodiments of the present invention or some of its technical features that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of the present invention or the foregoing embodiments, in conjunction with common general knowledge, ordinary technical knowledge in the art, and / or existing technology, should all be included within the scope of protection of the present invention.
