Description

Technical Field

[0001] This application relates to integrated bathroom manufacturing technology, and in particular to a modular bathroom chassis and an integrated bathroom using the same. Background Technology

[0002] As a modern bathroom renovation solution, prefabricated bathrooms have gained popularity among many consumers due to their convenient installation, excellent waterproofing, and durability. Prefabricated bathrooms design various bathroom components, such as toilets and sinks, as modules. These modules can be manufactured and assembled in the factory, then transported to the installation site for assembly, completing the bathroom renovation.

[0003] The bathroom base is a core module in a complete bathroom system. Installed on the bathroom floor, it provides waterproofing and structural support. Bathroom bases typically consist of multiple components, including interlocking blocks. Positioning and installing these components is difficult and time-consuming, significantly impacting installation efficiency.

[0004] For example, Chinese patent CN206659722U discloses a bathroom chassis, which includes a chassis body. The chassis body includes an outer mold, an inner mold, and a filling layer. The outer mold includes a bottom mold and side molds. The side molds protrude in the same direction and connect to the four sides of the bottom mold, forming a first casting space. The inner mold is set inside the outer mold and, together with the side molds, forms a second casting space that communicates with the first casting space. The filling layer fills the first casting space and, together with the bottom mold, forms the bottom wall of the chassis body. The filling layer fills the second casting space and, together with the side molds and the inner mold, forms the side walls of the chassis body. The mold used to form the bathroom chassis pours ultra-high performance concrete (i.e., the filling layer) between the inner mold and the outer mold to form a finished integral bathroom chassis. Because this integral bathroom chassis is poured with concrete, it is difficult to repair if damaged in the middle, and its overall weight is too large, increasing the difficulty of transportation and installation. This has led to the emergence of patent application CN115227125A, which specifically addresses the installation of this type of bathroom chassis.

[0005] Chinese patent CN109057412B also discloses a polyurethane bathroom base and its manufacturing method. The polyurethane bathroom base includes a waterproof layer and a skeleton layer. The waterproof layer is a polyurethane elastomer or a first rigid polyurethane foam. The skeleton layer is laid below the waterproof layer and is a composite layer formed by mixing a second rigid polyurethane foam and glass fiber. In the above-mentioned polyurethane bathroom base, the composite layer formed by mixing the second rigid polyurethane foam and glass fiber has extremely strong adhesion and can firmly bond to the waterproof layer. At the same time, it has high rigidity and bending strength, and can easily withstand the upper load of the polyurethane bathroom base. Polyurethane material has a series of advantages, but due to the overall foaming process, it is difficult to replace if there is local damage. In addition, the service life of polyurethane is not as long as that of ceramic tiles, and it is easy to damage its appearance due to bumps and knocks over time. Moreover, its coefficient of thermal shrinkage is different from that of ceramic tiles, making it difficult to further meet the personalized requirements of users. Summary of the Invention

[0006] In view of this, this application provides a modular bathroom chassis, a method for manufacturing the same, and an integrated bathroom using the same, in order to at least partially solve the above-mentioned technical problems.

[0007] To address the aforementioned technical problems, the present invention provides a modular bathroom chassis, comprising a chassis module unit. The chassis module unit includes an outer frame and a plurality of chassis modules surrounded by the outer frame. Each chassis module includes a second protrusion, and the outer frame includes a third protrusion. The second and third protrusions are used to engage with sealing grooves on a bracket to simultaneously limit the outer frame and chassis modules on the bracket. The bracket is used to be laid below to support the chassis module unit.

[0008] On the other hand, the present invention also provides an integrated bathroom, wherein the base plate of the integrated bathroom adopts the modular bathroom chassis as described above.

[0009] The implementation of the modular bathroom chassis in this application enables standardized production and maintains a safety stock. When an order comes in, the appropriate modules can be selected and combined to form the desired product, achieving rapid delivery. It also fulfills the original intention of flexible production for bathroom chassis, truly achieving flexible manufacturing and meeting over 90% of market demand. Other advantages of this application can be realized and obtained through the solutions described in the specification and accompanying drawings. Attached Figure Description

[0131] Figure 29 for Figure 4 A magnified view of part D in the diagram. Figure 30 This is a partial cross-sectional schematic diagram of the modular bathroom chassis of this exemplary embodiment. As shown, multiple chassis components 7 are mounted on the bracket 4, that is, the chassis bracket 54 is placed on the bracket 4, as... Figure 29As shown, the first bracket 78 supports the joint position of the two chassis components 7. The splicing blocks 54 of the two chassis components 7 abut against each other, forming a first joint 8. This first joint 8 can be filled with waterproof material to prevent water ingress, forming a first layer of seal. The first joint 8 corresponds to a sealing groove 83 between two second positioning protrusions 37. A second protrusion 69 extends into the sealing groove 83 between the two second positioning protrusions 37, and sealant is provided in the sealing groove 83, forming a second layer of seal. The third positioning protrusion 37 and the third positioning groove 38 are inserted to form a positioning. A sealing element 93, i.e., a second sealing ring 80, is provided between the third positioning protrusion 37 and the third positioning groove 38. The first protrusion 70 of the third component 60 abuts against the second support surface 85 of the first bracket 78, forming support, and the abutment also forms a structural seal, constituting a fourth layer of seal.

[0132] The chassis component 7 and the outer frame 2 are both mounted on the bracket 4 near the edge of the outer frame 1, that is, the chassis bracket 54 and the outer frame 2 are placed on the bracket 4, just as... Figure 30As shown, the second bracket 79 supports the outer frame 2 and the chassis component 7 near the edge of the outer frame 1. The first positioning protrusion 35 and the third positioning protrusion 37 of the second bracket 79 are arranged at intervals, forming a sealing groove 83 between them. The first support surface 84 is located on the side of the first positioning protrusion 35 away from the third positioning protrusion 37, and the second support surface 85 is located on the side of the third positioning protrusion 37 away from the first positioning protrusion 35. The third positioning protrusion 37 of the second bracket 79 and the third positioning groove 38 of the chassis bracket 54 are inserted to form a positioning. A second sealing ring 80 is provided between the third positioning protrusion 37 and the third positioning groove 38. The first protrusion 70 of the third component 60 abuts against the second support surface 85 of the second bracket 79, forming support, and the abutment also forms a structural seal. The second protrusion 69 of the third component 60 extends into the sealing groove 83 between the first positioning protrusion 35 and the second positioning protrusion 37. The third protrusion 50 of the second component 26 extends into the sealing groove 83 between the first positioning protrusion 35 and the second positioning protrusion 37. Sealing adhesive is provided in the sealing groove 83. The first positioning groove 36 of the outer frame 2 and the first positioning protrusion 35 of the second bracket 79 are correspondingly inserted to form a positioning. The first positioning protrusion 35 and the first positioning groove 36 are provided with a first sealing ring 74. The fourth abutting surface 52 of the second component abuts against the first supporting surface 84 of the first bracket 79 to form a support, and the abutment also forms a structural seal. The vertical plate 65 of the chassis bracket 54 abuts against the outer frame 2, that is, the second end face 72 of the vertical plate 65 abuts against the outer frame 2. The end of the vertical plate 65 away from the bracket 4 protrudes from the end face of the outer frame 2 away from the bracket 4, so that the second end face 72 of the vertical plate 65 and the end face of the outer frame 2 away from the bracket 4 form a concave angle. The first chamfer 48 can be filled with sealant to ensure the seal between the outer frame 2 and the chassis component 7. The end of the splicing block 53 away from the bracket 4 protrudes from the end face of the vertical plate 65 away from the main body 64 of the component, so that a space for installing a wall panel (not shown in the figure) is formed between the splicing block 53 and the edge frame 1. At the same time, the sealing groove 83 corresponds to the abutment point between the outer frame 2 and the chassis module 3 in the first direction.

Figure 30 and Figure 31As shown, when the edge frame 1 and the outer frame 2 are connected, the second positioning protrusion 20 of the edge frame 1 is inserted into the second positioning groove 30 of the outer frame 2 to form a positioning. The second positioning groove 30 is filled with sealant (not shown in the figure) to improve the sealing effect. The baffle 21 of the edge frame 1 is disposed in the first groove 31. A first gap 81 is provided between the end of the baffle 21 away from the edge body 19 and the groove wall of the first groove 31 near the chassis module 3. The first gap 81 can be filled with sealant. The first abutting surface 22 of the edge frame 1 can abut against the third abutting surface 32 of the outer frame 2. At the same time, the baffle 21 also abuts against the bottom wall of the first groove 31, forming that the outer frame 2 supports the edge frame 1. In addition, the first connection 18 on the edge frame 1 and the second connection 29 on the outer frame 2 are arranged alternately, making the gap between the edge frame 1 and the outer frame 2 more tortuous, further improving the waterproof effect.

[0134] Example 2

[0135] This embodiment protects an integrated bathroom, including wall panels (not shown in the figure), a ceiling panel (not shown in the figure), and the aforementioned modular bathroom chassis.

[0136] In conjunction with the above embodiments, the modular bathroom chassis of this example has a first positioning structure, a second positioning structure, and a third positioning structure. During the installation process of the modular bathroom chassis, the chassis module 3 and the outer frame 2 are first installed onto the bracket 4. During this process, the first positioning structure enables the outer frame 2 to be quickly positioned and installed onto the bracket 4, and the third positioning structure enables the chassis module 3 to be quickly positioned and installed onto the bracket 4, eliminating the need for manual positioning and calibration, thus saving time. Furthermore, when the edge frame 1 is subsequently installed onto the outer frame 2, the second positioning structure enables the edge frame 1 to be quickly positioned and installed onto the outer frame 2. Meanwhile, the modular bathroom chassis can also form four layers of waterproofing, which significantly improves the waterproofing effect. For example, the first joint 8 between the two chassis components 7 can be filled with waterproof material to prevent water from entering the first joint 8, forming the first layer of seal; the second protrusion 69 extends into the sealing groove 83 between the two second positioning protrusions 37, and the sealing groove 83 is provided with sealant to form the second layer of seal; a sealing element 93, namely the second sealing ring 80, is provided between the third positioning protrusion 37 and the third positioning groove 38 to form the third layer of seal; the first protrusion 70 of the third component 60 abuts against the second support surface 85 of the first bracket 78 to form a structural seal, constituting the fourth layer of seal.

[0137] Example 3

[0138] Traditional wall panels and flooring come in fixed sizes, such as squares of 400mm×400mm, 600mm×600mm, and 800mm×800mm, or rectangles of 400mm×1200mm, 600mm×1200mm, and 800mm×1200mm (equal height design). When a certain area is covered and the edge is reached, wall panels or flooring with a specific allowance are cut or customized to ensure full coverage.

[0139] To reduce raw material waste and achieve mass production, this embodiment employs a modular bathroom chassis to match different space dimensions. The implementation of the modular bathroom chassis enables standardized production. In this embodiment, the chassis modules are manufactured using a chassis modularity rule, and flexible production of the modular bathroom chassis is achieved through the combination of these modules.

[0140] The main chassis module includes a long side and a short side. The long side includes 'a' different specifications using modular settings, and the short side includes 'b' different specifications using modular settings. Thus, the main chassis module has a×b different specifications using modular settings. Where 'a' is a natural number and 2≤a≤12; and 'b' is a natural number and 2≤b≤15.

[0141] The compensation allowance chassis module is used to fill the remaining allowance in the user's construction dimensions, thus avoiding the need to reprocess the main chassis module.

[0142] The main chassis module and the combination of the compensation margin chassis module selected as needed can meet the construction size requirements of any user within a predetermined value range. In the combination, the number of compensation margin chassis modules is 0, 1 or 2.

[0143] The long side and short side specifications of the main chassis module are set in pairs. The sum of the two pairs of specifications is related to the size of the raw materials used to manufacture the main chassis module, thereby reducing waste of scrap materials.

[0144] The specifications of the main chassis module are larger than those of the compensation margin chassis module;

[0145] The compensation margin chassis module includes a long side and a short side. The specification of the long side is an integer multiple of 10mm increments. The specification of the short side is the same as that of the short side of the main chassis module.

[0146] Example 4

[0147] This embodiment describes a splicing block manufactured using a modular rule, comprising:

[0148] Main chassis modules for the dry area (unit mm×mm): 400×1000, 500×1000, 600×1200, 800×1200, 1100×1100 respectively;

[0150] Compensation margin chassis modules (unit mm): 210, 220, 230, 240, 250 respectively;

[0151] Therefore, for any construction dimensions of a user's actual apartment that are greater than or equal to 3m × 2m, a modular bathroom chassis of the corresponding size can be used, which can be implemented by combining any of the following chassis modules:

[0152]

[0153] Therefore, it can be seen that by combining the construction components of the present invention with modular splicing blocks, any size can be achieved by the user in actual construction. For the scheme that can be implemented in multiple ways, the user can determine the final scheme based on the aesthetics of the arrangement of the construction components and personal preferences. Once the user selects the construction scheme, the floor can be installed according to the determined splicing blocks.
