Description

Technical Field

[0001] This invention belongs to the field of kitchen and bathroom furniture technology, and relates to a cabinet that makes composite use of space, and more particularly to a sustainable functional cabinet with a reserved equipment compartment. Background Technology

[0002] Currently, widely used kitchen cabinets mainly consist of the cabinet body, countertop, hardware, and appliances. The cabinet body is manufactured through on-site measurement and design, factory processing of the boards, and transportation to the site for installation. Standard cabinet bodies are primarily modular with a depth of 600mm, and widths are available in various common sizes such as 400mm, 600mm, 800mm, and 900mm, supplemented by custom-made corner pieces to meet the requirements of different space dimensions. Common cabinet body materials include particleboard, eco-friendly boards, and solid wood. Currently, particleboard is the most commonly used and cost-effective material for kitchen cabinet bodies on the market. The boards are cut to the designed dimensions in the factory, and the cut edges are machine-sealed for moisture resistance and aesthetic appeal.

[0003] Traditional kitchen cabinet installation requires drilling holes in the cabinet body according to the locations of water, electricity, and gas connections. This process is noisy, produces a lot of debris, and is prone to errors and disputes due to manual operation. Later, when homeowners add appliances such as dishwashers, water purifiers, and small water heaters, the water and electricity lines need to pass through the cabinet, requiring holes to be drilled in the cabinet panels, causing secondary damage. Since the edges of the panels cannot be sealed after drilling, the cabinets are susceptible to moisture, inevitably shortening their lifespan and significantly affecting their aesthetics.

[0004] Moreover, kitchen appliances are constantly evolving, making it difficult to anticipate the addition and replacement of internal equipment when designing cabinets. Even for the same type of equipment, there are different sizes available, and the dimensions and water and electricity interfaces are also different. Periodic product iterations and upgrades make it almost impossible to reserve space for equipment. As a result, various kitchen appliances are randomly placed in the cabinets, leading to low utilization of storage space.

[0005] Furthermore, the water and electricity pipes for various appliances in the kitchen are intertwined and overlapping inside and outside the cabinets, making it difficult to install, repair, and operate the appliances. This also occupies a significant amount of cabinet space, resulting in low space utilization. Currently, hot and cold water pipes are generally buried in the walls, while drain pipes are buried underground. Changing the sink's location requires civil engineering work, which is uneconomical, causes significant pollution, and is difficult to repair. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing kitchen cabinets, such as cluttered installation of various equipment, low space utilization, overlapping and intertwined water and electricity pipelines inside and outside the cabinets, and large construction volume that is difficult to maintain. The invention proposes a sustainable functional cabinet with reserved equipment interlayer.

[0007] With the increasing number of modern kitchen appliances and the ever-increasing scarcity of cabinet space, a depth of around 400mm is generally considered reasonable for cabinet utilization. This invention provides a sustainable functional cabinet with a reserved equipment compartment, which divides the typical 600mm depth of cabinets by approximately 100mm-200mm at the back to serve as an equipment compartment. This modular design allows for factory processing, eliminating the need for on-site installation that would damage or alter the cabinet structure. The cabinet is designed to be sustainable for the use of various appliances, offering broad applicability, further optimizing cabinet space utilization, and enhancing the quality of life.

[0045] The present invention adopts the above technical solution and has the following technical effects compared with the prior art:

[0046] (1) Combine the modular design of the cabinet and reserve a space of 100mm-250mm behind it to build an equipment mezzanine unit. The equipment mezzanine unit is connected to the bottom space of the cabinet so as to connect the drain pipe. The width of the equipment mezzanine unit can cover each water, electricity and gas interface and its corresponding kitchen equipment unit. And by setting an inspection door module on the front of the equipment mezzanine, it is convenient to install and maintain the equipment.

[0047] (2) When adding electrical appliances to the kitchen, open the access door module and install it against the wall or back panel in the empty space inside the equipment mezzanine unit; after the access door module is closed, the cabinet space in front of the cabinet is more complete and beautiful, and the usage efficiency is higher.

[0048] (3) All water, electricity and gas pipelines of all kitchen equipment units are installed and connected in the equipment mezzanine unit. Since all electrical equipment is arranged horizontally in the equipment mezzanine unit, all water, electricity and gas pipelines are fixed to the back wall or back panel, and the pipeline layout is more reasonable and clear. Moreover, the water supply and drainage pipes are all exposed pipes, which are not restricted by the interface position and can be freely connected to various water-using equipment. At the same time, it is easy to install, inspect and maintain.

[0049] (4) The maintenance door module on the front side of the equipment mezzanine unit has a variety of structural forms, such as fully enclosed full height type, upper reserved connection type, lower reserved connection type and upper and lower reserved connection type. It adopts the form of sliding door, roller shutter door, etc. It can be installed on the corresponding side plate mounting hole in a detachable manner according to the size of the equipment to be installed in the equipment mezzanine, which is flexible and convenient to use.

[0050] (5) Use a mezzanine sealing module to seal the equipment mezzanine unit where no equipment pipelines pass through. The mezzanine sealing module consists of a bottom plate and a side plate, with the same size as the reserved gap between the side plate and bottom plate of the cabinet module. It can be removed when the equipment mezzanine needs to be restored. The mezzanine sealing module is embedded in the reserved gap between the side wall, bottom and back plate to provide complete cabinet space. At the same time, the equipment mounting holes on the back plate can be used to fix the storage partitions in the kitchen cabinet.

[0051] (6) By partitioning off an independent space of about 100mm-250mm at the rear of the cabinet unit as an equipment mezzanine unit, the cabinet unit adopts several cabinet modules for free assembly, realizing modular factory processing. On-site installation does not require damage or modification of the cabinet modules. The cabinet modules are sustainable and widely applicable to the use of various equipment, further optimizing the utilization of cabinet space and improving the quality of life.

[0052] (7) The independently arranged back plate, the upper and lower ends of the sandwich enclosure module, the left and right side plates and the maintenance door module are fixedly connected together by the first and second connecting parts arranged symmetrically on the left and right sides, so as to realize the flexible disassembly of each unit module. The maintenance door module can be adjusted to move back and forth by installing the adjustment maintenance door module in different first limit slots. Attached Figure Description

[0068] The present invention will now be described in detail and specifically through specific embodiments to enable a better understanding of the invention. However, the following embodiments do not limit the scope of the invention.

[0069] like Figure 1 , Figure 2 , Figure 3 and Figure 33 As shown, a sustainable functional cabinet with reserved equipment mezzanine is provided. The main solution of this sustainable functional cabinet is to divide the cabinet into two spaces, front and back. The front is used as the cabinet space and the back is used as the equipment mezzanine space. The two are separated by an access door module. The position of the access door module can be adjusted forward and backward to meet the requirements of different sizes of equipment for mezzanine depth. Different modules can be freely combined to adapt to different equipment needs.

[0070] Specifically, the sustainable functional cabinet with reserved equipment compartment mainly includes cabinet unit 100, equipment compartment unit 200 and kitchen equipment unit 300. The equipment compartment unit 200 is formed laterally at the rear of the cabinet unit 100, and the kitchen equipment unit 300 is provided inside and / or outside the equipment compartment unit 200.

[0071] Cabinet Unit 100 is composed of several modular cabinet modules, each of which is an independent cabinet unit with an internal cavity. The cabinet unit mainly consists of a 600mm deep modular box, with several common widths including 400mm, 600mm, 800mm, and 900mm, supplemented by custom-made corner sizes to meet the requirements of different space dimensions.

[0072] The equipment mezzanine unit 200 is composed of the horizontally connected space at the rear of the cabinet unit 100. The equipment mezzanine unit 200 is the entire horizontally connected space at the rear of the cabinet unit 100 from left to right. That is, each cabinet module is divided into front and rear parts, and the equipment mezzanine unit 200 is formed at the rear of each module, while the conventional cabinet space is formed at the front.

[0073] The equipment mezzanine unit 200 is a modular unit that integrates with the cabinet, with a 100mm-250mm equipment mezzanine space reserved behind it. The equipment mezzanine space is connected to the bottom space of the cabinet to facilitate the connection of drainage pipes. The width of the equipment mezzanine covers all water, electricity and gas interfaces and their corresponding equipment.

[0074] The size of the equipment mezzanine unit 200 formed at the rear of the cabinet unit 100 is determined by the position of the access door module 201 arranged at its front. By setting the access door module 201 at the front of the equipment mezzanine unit 200 and fixing the access door module 201 to the side panel 102 of the cabinet unit 100, a certain depth space is formed between the inner side of the access door module 201 and the wall 001 or the back panel.

[0075] In order to meet the requirements of different sizes of equipment for the depth of the interlayer, the maintenance door module 201 is installed on the adjustable side plates 102 on both sides, and the side plates 102 are provided with a number of mounting holes for fixing the maintenance door module 201.

[0076] In one implementation, based on the structural features of the inspection door module 201, both ends of the inspection door module 201 are directly mounted to the side plate 102 using screws. The installation position of the inspection door module 201 can be adjusted by adjusting different mounting holes on the side plate 102, thereby achieving the purpose of adjusting the inspection door module 201 back and forth, so as to form an equipment mezzanine unit 200 with a certain depth inside the inspection door module 201.

[0077] In another implementation, the front access door module 201 is fixedly mounted on the side plate 102 using a corner plate or hinge with screws. Similarly, by adjusting the mounting position of the access door module 201 in different mounting holes, the front and rear adjustment of the access door module 201 can be achieved.

[0078] The kitchen equipment unit 300 contains various kitchen water and electricity equipment. These devices are installed inside or outside the equipment mezzanine unit 200, depending on their purpose and size. The common feature of these devices is that they are all connected to the pipeline modules installed inside the equipment mezzanine unit 200, realizing the laying of pipelines and various interface connections in the inner mezzanine.

[0079] In some of these embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 33 As shown, the cabinet unit 100 is arranged in an I-shape against the wall. An I-shaped equipment mezzanine unit 200 is formed between the rear of the cabinet unit 100 and the wall 001. The depth of the equipment mezzanine unit 200 varies in different cabinet module positions and is adjusted and controlled according to the installation position of the access door module 201.

[0080] In some embodiments, for different kitchen space layouts, the cabinet unit 100 is arranged in an L-shape against a corner, meaning the cabinet unit 100 has a corner and is positioned at the corner. An L-shaped equipment mezzanine unit 200 is formed between the rear of the cabinet unit 100 and the walls 001 on both sides of the corner. The depth of the equipment mezzanine unit 200 varies depending on the location of the cabinet module and is adjusted according to the installation position of the access door module 201.

[0081] In addition, in some other embodiments, the cabinet unit 100 can be arranged in a U-shape against the wall for different kitchen space layouts. That is, the cabinet unit 100 has two corners, which are set at one end of the kitchen and against the wall. Similarly, a U-shaped equipment mezzanine unit 200 is formed between the rear of the cabinet unit 100 and the wall 001. The depth of the equipment mezzanine unit 200 is different in different cabinet module positions and is adjusted and controlled according to the installation position of the access door module 201.

[0082] It should be noted that although the cabinet unit 100 has different structural forms, the equipment mezzanine unit 200 formed at its rear is connected from left to right, and an inspection door module 201 is provided on the front side of the equipment mezzanine unit 200 to enclose and separate the internal mezzanine space from the external cabinet space. Corresponding pipeline modules are laid in the equipment mezzanine unit 200, including but not limited to water and electricity pipes, gas pipes, etc.

[0083] In some of these embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the cabinet unit 100 is composed of several cabinet modules assembled sequentially, and adjacent cabinet modules are fixed together by buckles, screws, bolts or other installation methods.

[0084] Specifically, the cabinet module includes a base plate 101, side plates 102, a front panel 103, and legs 105. The base plate 101 is openable and located at the lower end of the left and right side plates 102. Specifically, the base plate 101 includes a first support plate 1011 and a second support plate 1012. The first support plate 1011 is horizontally positioned at the lower front end of the two side plates 102, with its two ends fixedly connected to the second support plate 1012 to support the base plate 101. There are two second support plates 1012, respectively located at the front and rear ends of the top of the left and right side plates 102, connecting the left and right side plates 102 and the front panel 103 supporting their tops. There are two side plates 102, spaced apart horizontally and arranged vertically, with their bottom ends connected to the base plate 101 and their top ends connected to the front panel 103. This forms a complete cabinet space between the base plate 101, side plates 102, front panel 103, and legs 105.

[0085] Similar to existing kitchen cabinets, this cabinet module features a cavity with a certain depth, ranging from 500-800mm, preferably 600mm, and widths of 400mm, 600mm, 800mm, and 900mm. The front of the cabinet module has a door 108, which can accommodate multiple drawers 107. Of course, depending on actual needs and specific kitchen layouts, such as in compact apartment spaces, the cabinet module can be made smaller or larger, adjusted as required.

[0086] Furthermore, to demonstrate the integrated design of the countertop of cabinet unit 100, after several cabinet modules are sequentially assembled, the adjacent top panels 103 are directly and seamlessly connected, forming the countertop of cabinet unit 100. The panels 103 of several cabinet modules are made into a single structure. After several cabinet frames excluding the panels 103 are sequentially assembled, the panels 103 are then installed as a whole onto the cabinet frames to form cabinet unit 100.

[0087] As another preferred embodiment, to reflect the integration of the countertop of the cabinet unit 100, unlike the above, each cabinet module has an independent panel 103 on its top. When several cabinet modules are spliced ​​together to form an I-shaped, L-shaped, or U-shaped structure, the corresponding panels 103 on the top are also arranged sequentially. To avoid unevenness and unsightly appearance of the countertop due to gaps between the panels 103, a second panel is additionally laid on top of the panels 103. This second panel can be one or more, and the area of ​​a single panel is at least larger than the area of ​​two panels 103.

[0088] In some of these embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, a number of panels 103 spliced ​​together in sequence and the second panel on top of them form the countertop of the cabinet, and sink mounting holes and gas stove mounting holes are provided on the panels 103 and the second panel.

[0089] As another preferred embodiment, a sink, basin, or other water-using equipment is installed at the sink mounting hole on the countertop. The water supply or drainage pipes of the sink, basin, or other water-using equipment are connected to the horizontally arranged water supply line 203 and drainage line 204 within the equipment mezzanine unit 200 through the sink mounting hole. By concealing the pipe joints and water supply and drainage pipes of the sink, basin, or other water-using equipment within the equipment mezzanine unit 200 through the sink mounting hole, the water supply and drainage pipes and other structures are avoided from being cluttered in the front cabinet space, effectively improving the utilization rate of the front cabinet space.

[0090] The gas stove is installed at the gas stove mounting hole on the countertop. The gas stove is connected to the gas pipeline 205 arranged horizontally inside the equipment mezzanine unit 200 through the gas stove mounting hole via a flexible hose. Thus, the gas pipeline 205 used to supply gas and the flexible hose and connectors connecting the gas stove are all arranged in a hidden structure to avoid being directly exposed in the front cabinet space.

[0091] In some of these embodiments, such as Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, according to the conventional installation requirements for drain pipes, drain pipes in the kitchen are generally laid flat against the wall. Therefore, a reserved gap is provided on the rear side of the bottom plate 101 of at least one cabinet module as a pipe passage. The size of the gap can be referenced to the side plate 102, and the shape can be U-shaped or pre-reserved as a whole. It connects downwards to the cabinet bottom space formed by the bottom plate 101 and its bottom support legs 105. Water-using equipment installed inside or outside the equipment mezzanine unit 200 is connected to the drain pipe 204 of the cabinet bottom space through this reserved gap via pipes.

[0092] As a preferred implementation, such as Figure 4 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 15 As shown, a C-shaped gap is provided on the rear side of the side panel 102 against the wall, serving as a pipeline channel. This gap can be enlarged or reduced to suit different usage needs; a width of 100mm is recommended. In other words, the rear end of the side panel 102 is C-shaped with a hollow slot, retaining both top and bottom ends for connecting and fixing the back panel 104. This C-shaped side panel 102 also serves to assemble the mezzanine sealing module 202 to seal the equipment mezzanine.

[0093] As a preferred implementation, such as Figure 5 A pre-reserved gap is provided on the rear side of side panel 102 against the wall. This gap is L-shaped, retaining only the top portion, while the bottom connects to the lower cabinet space, serving as a conduit for wiring. The gap can be enlarged or reduced to suit different usage needs; a 100mm width is recommended. This allows the lower ends of at least two adjacent cabinet modules to be connected, forming a large mezzanine space to accommodate large equipment installations. Alternatively, the pre-reserved gap can be L-shaped, retaining only the bottom portion, with the top portion connecting left and right, to connect the tops of at least two adjacent cabinet modules.

[0094] As another preferred embodiment, such as Figure 6A reserved gap is provided on the rear side of the side panel 102 against the wall to serve as a pipeline channel. The gap can be expanded or reduced according to different usage needs. The reserved gap is I-shaped, meaning that the rear end of the side panel 102 is not connected to the wall or the back panel 104, but the interlayer space on both sides of the side panel 102 is fully connected.

[0095] Furthermore, in some embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 15 As shown, the cabinet unit 100 also includes a back panel 104, which is an integral part and is completely set on the back of several cabinet modules. It is fixed to the base plate 101 and / or side wall 102 by corner plates or screws.

[0096] As one alternative, the back panel 104 consists of several independent back panel units, which are respectively installed on the back of each cabinet module. Specifically, the upper and lower ends of the back panel 104 are respectively connected to the upper and lower ends of the side panel 102 with screws.

[0097] In some embodiments, the back panel 104 is designed with arrayed pre-drilled holes for equipment installation. These holes facilitate the fixing of exposed water, electricity, and gas pipes, wiring between equipment, and the suspended installation of individual devices. The back panel 104 can be made of materials such as MDF, solid wood, metal sheet, or metal mesh. The upper and lower ends of the back panel 104 are respectively connected to the upper and / or lower ends of the side panel 102, or to the rear ends of the base plate 101 and the front panel 103.

[0098] As one alternative, the backplate 104 can be used as an option, either without holes and directly fixed with screws, or without a backplate and installed directly on the exposed wall 001.

[0099] In some of these embodiments, such as Figure 2 and Figure 3 As shown, the maintenance door module 201 can be a hinged door, sliding door, or roller shutter, etc., and can be installed on the corresponding mounting holes of the side plate 102 according to the size of the equipment to be installed in the equipment mezzanine. A conventional hinged door is preferred, as it facilitates equipment installation and troubleshooting within the mezzanine space. More preferably, the maintenance door module 201 is a sliding door, using a left-right sliding opening mechanism, which facilitates opening the maintenance door module 201, and is also more economical and durable.

[0100] As one of the preferred embodiments, such as Figure 9As shown, the maintenance door module 201 serves as the front door of the equipment mezzanine unit 200. Both the upper and lower ends of the maintenance door module 201 have pre-drilled cable trays, or cable routing through holes can be opened on the maintenance door module 201 as needed. Furthermore, the maintenance door module 201 is detachable for convenient equipment installation and maintenance.

[0101] When adding equipment to the kitchen, open the access door module 201 and install it against the wall in the empty space within the equipment compartment unit 200. With the access door module 201 closed, the front cabinet space is more complete and aesthetically pleasing, and its usability is higher.

[0102] The maintenance door module 201 adopts a fully enclosed through-type structure, meaning that the top and bottom of the maintenance door module 201 do not have reserved openings, which is suitable for scenarios where there is no need for equipment connection between the front cabinet space and the rear equipment mezzanine space.

[0103] In this configuration, the kitchen equipment unit 300 is housed within the inner equipment mezzanine unit, while the outer cabinet space serves as an independent storage area. The two are fully enclosed by an access door module 201. Furthermore, the front cabinet space can be equipped with several drawers for storage, maximizing space utilization.

[0104] As another preferred embodiment, the access door module 201 adopts an upper or lower reserved connection port structure, that is, a connection port is reserved at the top or bottom of the access door module 201, which is suitable for scenarios where there is a need for equipment connection between the front cabinet space and the rear equipment mezzanine space. In this case, the kitchen equipment unit 300 is set in the outer cabinet space, and its water and electricity pipelines are connected to the pipeline module in the equipment mezzanine unit 200 through the reserved connection port at the top or bottom.

[0105] As another preferred embodiment, such as Figure 8 As shown, the maintenance door module 201 adopts a structure with pre-reserved communication openings at both the top and bottom. That is, communication openings are reserved at the top and bottom of the maintenance door module 201, which is suitable for scenarios where there is a need for equipment communication between the top and bottom of the front cabinet space and the rear equipment mezzanine space.

[0106] In some of these embodiments, such as Figure 13 , Figure 14 and Figure 15 As shown, in order to provide complete internal cabinet space within the cabinet module, a mezzanine sealing module 202 is also provided within the equipment mezzanine unit 200. The mezzanine sealing module 202 has a U-shaped structure, and its dimensions are the same as the reserved gaps between the bottom plate 101 and the side plate 102 of the cabinet unit 100. It is used to seal the mezzanine space where no equipment pipelines pass through. When it is necessary to restore the equipment mezzanine unit 200 in the internal cabinet space, the mezzanine sealing module 202 can be removed.

[0107] The mezzanine enclosure module 202 is installed on the mounting holes of the back panel 104 or set at the rear end of the side panel 102 to provide complete cabinet space. Meanwhile, the equipment mounting holes on the back panel 104 can be used to fix storage shelves inside the kitchen cabinet.

[0108] When there is no equipment in the mezzanine unit 200, the gap in the mezzanine space is filled by the mezzanine sealing module 202 of the standard module, thus obtaining a complete cabinet space with a depth of 600mm. When equipment needs to be installed, only this mezzanine sealing module 202 needs to be removed, thus truly achieving non-destructive, sustainable and functional cabinet materials.

[0109] The mezzanine enclosure module 202 mainly consists of a mezzanine enclosure base plate 2021 and mezzanine enclosure side plates 2022. There are two mezzanine enclosure side plates 2022, which are respectively vertically installed at the left and right ends of the mezzanine enclosure base plate 2021, and are used to seal the equipment mezzanine of cabinets where no equipment pipelines pass through.

[0110] Specifically, the mezzanine-sealed bottom plate 2021 is embedded in the reserved gap inside the bottom plate 101, and the mezzanine-sealed side plates 2022 on both sides are correspondingly embedded in the reserved gaps inside the side plates 102, thereby separating the equipment mezzanine space inside the cabinet module from the equipment mezzanine units 200 on both sides. Furthermore, by opening or disassembling the maintenance door module 201, the equipment mezzanine unit 200 separated at the rear is connected to the cabinet space at the front, thus forming a complete cabinet space with a depth of 600mm.

[0111] In one preferred embodiment, to facilitate the installation of the sandwich sealing module 202, the bottom sandwich sealing base plate 2021 is completely embedded in the reserved gap inside the base plate 101. A sandwich sealing groove 2023 is provided on the outer wall of the lower end of the sandwich sealing side plate 2022, and the module is correspondingly mounted in the reserved gap of the side plate 102 through the sandwich sealing groove 2023. That is, the lower end of the sandwich sealing module 202 is correspondingly embedded between the two side plates 102, and the two sides are correspondingly embedded in the reserved gap inside the side plates 102. This seals the reserved gaps opened on the base plate 101 and the side plates 102.

[0112] In some embodiments, to improve the ease of installation of various structural modules such as the cabinet unit 100 and the equipment mezzanine unit 200, such as Figure 19 , Figure 20 and Figure 21As shown, two sets of first connectors 400 and second connectors 500 are used to fix the four corners of the door frame 2011 of the inspection door module 201. The two sets of first connectors 400 are arranged symmetrically from left to right and are installed at the top two ends of the inspection door module 201, respectively connecting the corresponding side wall 102, panel 103, back plate 104 and sandwich sealing module 202; the two sets of second connectors 500 are arranged symmetrically from left to right and are installed at the bottom two ends of the inspection door module 201, respectively connecting the corresponding bottom plate 101, side wall 102, back plate 104 and sandwich sealing module 202.

[0113] Specifically, for the maintenance door module 201 with a full-height structure, a structure with a pre-reserved connection opening at the top, a structure with a pre-reserved connection opening at the bottom, or a structure with pre-reserved connection openings at both the top and bottom, different structural designs of the door frame 2011 are adopted, so that a connection opening is reserved at the top or bottom of the door frame 2011 or no connection opening is reserved.

[0114] like Figure 22 As shown, the first connector 400 includes a first connecting plate 401, a second connecting plate 402, a third connecting plate 403, a fourth connecting plate 406, a fifth connecting plate 407, and a sixth connecting plate 408, which are integrally formed.

[0115] The first connecting plate 401 is a horizontally arranged long strip-shaped structure, with its top attached to the bottom of the panel 103, and has several through holes, which are fixed to the bottom of the panel 103 by screws inserted into the through holes.

[0116] The second connecting plate 402 and the third connecting plate 403 are vertically downwardly disposed on the inner side of the first connecting plate 401, arranged at a right angle. One end of the third connecting plate 403 is connected to the second connecting plate 402, and the width of the second connecting plate 402 is greater than the width of the third connecting plate 403, so as to form an opening between the lower edge of the third connecting plate 403 and the side edge of the second connecting plate 402.

[0117] The second connecting plate 402 and the third connecting plate 403 are detachably mounted on the top of the inner end of the side plate 102 by screws through through holes thereon. It should be noted that the second connecting plate 402 is disposed on the inner side wall of the extension 1021 at the inner end of the side plate 102, and the third connecting plate 403 is fixedly disposed on the side plate 102 for mounting and fixing the maintenance door module 201.

[0118] To enable the third connecting plate 403 to adjust and limit the access door module 201, several inwardly flanged first stops 404 are spaced apart on the inner side of the lower edge of the third connecting plate 403. These first stops 404 are L-shaped and integrally formed on the third connecting plate 403, forming a first limiting groove 405 between adjacent first stops 404. The left and right top edges of the door frame 2011 are correspondingly embedded between the left and right first limiting grooves 405. By adjusting the position of the door frame 2011 in different front and rear first limiting grooves 405, and in conjunction with the second connecting piece 500, the access door module 201 can be flexibly controlled to move back and forth within the cabinet space, thereby achieving the purpose of adjusting the width and depth of the equipment mezzanine unit 200 and the depth of the cabinet space.

[0119] The fourth connecting plate 406 is horizontally disposed on the outer side of the lower edge of the third connecting plate 403, with one end integrally formed with the lower edge of the third connecting plate 403. A downwardly arranged fifth connecting plate 407 is disposed on the outer side of the fourth connecting plate 406, and the fifth connecting plate 407 is integrally formed with the fourth connecting plate 406. Figure 19 It can be seen that the fourth connecting plate 406 and the second connecting plate 402 form a first mounting position, and the fifth connecting plate 407 is perpendicularly connected to the fourth connecting plate 406, forming a second mounting position at a right angle between them.

[0120] The first mounting position formed between the fourth connecting plate 406 and the second connecting plate 402 is correspondingly located at the bottom of the top extension section 1021, and the second mounting position of the fifth connecting plate 407 is correspondingly located at the top of the sandwich panel 2022. This simultaneously limits the upper side panel 102 and the lower sandwich panel 202. Similarly, through holes are provided on the fourth connecting plate 406 and the fifth connecting plate 407, and screws can be used to install the fourth connecting plate 406 and the fifth connecting plate 407 onto the extension section 1021 and the sandwich panel 202, respectively.

[0121] The sixth connecting plate 408 is a square plate structure, with its upper side welded to the fifth connecting plate 407. The sixth connecting plate 408 has through holes, and screws can be used to fix the sixth connecting plate 408 to the top of the back plate 104 or the wall 001.

[0122] like Figure 23 As shown, the second connector 500 also includes a first connecting plate 501, a second connecting plate 502, a third connecting plate 503, a fourth connecting plate 506, a fifth connecting plate 507, and a sixth connecting plate 508, which are integrally formed.

[0123] The first connecting plate 501 is a horizontally arranged elongated plate structure, with its top forming a support plate for supporting the inner end of the base plate 101. It also has several through holes, through which screws are inserted and fixed to the bottom of the base plate 101.

[0124] The second connecting plate 502 is vertically arranged on the inner end of the first connecting plate 501, at a right angle to the first connecting plate 501. One end of the second connecting plate 502 is horizontally connected to the third connecting plate 503, and the width of the second connecting plate 502 is greater than the width of the third connecting plate 503, so as to form an opening between the lower edge of the third connecting plate 503 and the side edge of the second connecting plate 502.

[0125] The second connecting plate 502 and the third connecting plate 503 are detachably mounted on the top of the inner end of the side plate 102 by screws through through holes opened thereon. It should be noted that the second connecting plate 502 is disposed on the inner side wall of the extension 1021 at the inner end of the side plate 102, and the third connecting plate 503 is fixedly disposed on the side plate 102 for mounting and fixing the maintenance door module 201.

[0126] To enable the third connecting plate 503 to adjust and limit the lower end of the inspection door module 201, several inwardly flanged first stops 504 are spaced apart on the inner side of the lower edge of the third connecting plate 503. These first stops 504 are L-shaped and integrally formed on the third connecting plate 503, forming a first limiting groove 505 between adjacent first stops 504. The left and right top edges of the door frame 2011 are correspondingly embedded between the left and right first limiting grooves 505. By adjusting the position of the door frame 2011 in different front and rear first limiting grooves 505, and in conjunction with the second connecting piece 500, the inspection door module 201 can be flexibly controlled to move back and forth within the cabinet space, thereby achieving the purpose of adjusting the width and depth of the equipment mezzanine unit 200 and the depth of the cabinet space.

[0127] The fourth connecting plate 506 is horizontally disposed on the outer side of the upper edge of the third connecting plate 503, with one end integrally formed with the top end of the third connecting plate 503. A fifth connecting plate 507, arranged upwards, is disposed on the outer side of the fourth connecting plate 506, and the fifth connecting plate 507 is integrally formed with the fourth connecting plate 506. Figure 19 It can be seen that the fourth connecting plate 506 and the second connecting plate 502 form a first mounting position, and the fifth connecting plate 507 is perpendicularly connected to the fourth connecting plate 506, forming a second mounting position at a right angle between them.

[0128] The first mounting position formed between the fourth connecting plate 506 and the second connecting plate 502 is correspondingly located at the top of the lower extension section 1021, and the second mounting position of the fifth connecting plate 507 is correspondingly located in the interlayer sealing groove 2023. This simultaneously limits the positioning of the lower opposite side plate 102 and the upper interlayer sealing module 202. Similarly, through holes are provided on the fourth connecting plate 506 and the fifth connecting plate 507, and screws can be used to install the fourth connecting plate 506 and the fifth connecting plate 507 onto the extension section 1021 and the interlayer sealing module 202, respectively.

[0129] Similarly, the sixth connecting plate 508 is a square plate structure, with its upper side welded to the fifth connecting plate 507, and a through hole is provided on the sixth connecting plate 508. The sixth connecting plate 508 can be fixedly installed on the lower end of the back plate 104 or the wall 001 by screws.

[0130] like Figures 24 to 32 As shown, in this embodiment, the independently arranged back plate 103, the upper and lower ends of the interlayer sealing module 202, the left and right side plates 102 and the maintenance door module 201 are fixedly connected together by the first connecting member 400 and the second connecting member 500 arranged symmetrically on the left and right sides, so as to realize the flexible disassembly of each unit module, and the maintenance door module 201 can be adjusted to move back and forth by installing the maintenance door module 201 in different first limiting grooves 405.

[0131] In another preferred embodiment, the reserved gap at the rear end of the side panel 102 is an inverted L-shaped structure, with the lower end of the reserved gap being open and connecting downwards to the bottom space of the cabinet. When the mezzanine sealing module 202 is installed in the corresponding equipment mezzanine unit 200, the two ends of the bottom of the mezzanine sealing module 202 are directly supported on the support legs 105 of the cabinet, using the support legs 105 as support, and are connected to the side panel 102 through the second connector 500, or fixedly installed on the mounting holes of the back panel.

[0132] In some of these embodiments, such as Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 16 , Figure 17 , Figure 18 and Figure 33 As shown, before the building's civil construction, this sustainable functional cabinet can be used to directly connect the riser pipes, so that all the water and electricity lines of the kitchen equipment can be connected in the equipment mezzanine. Since all the equipment is arranged horizontally in the mezzanine, the pipeline layout is more reasonable and clear.

[0133] The pipeline module mainly includes water supply pipeline 203, drainage pipeline 204, power supply pipeline 209, and gas pipeline 205. All four pipelines (203, 204, 209, and 205) are installed exposed, arranged horizontally within the equipment mezzanine unit 200, mounted on the back panel 104 or wall. They are not restricted by interface locations and can be freely connected to various water-using devices, facilitating installation, inspection, and maintenance.

[0134] Specifically, such as Figure 1 , Figure 3 , Figure 8 and Figure 33 As shown, the water supply pipeline 203 is arranged horizontally in the upper middle part of the equipment mezzanine unit 200. Its inlet is connected to the vertically arranged water supply riser 206 inside the equipment mezzanine unit 200 through a bend in the pipe, or to the outlet / faucet of the existing wall-mounted water supply pipe. The outlet of the water supply pipeline 203 passes directly upward through the sink mounting hole on the panel 103 to connect directly to the sink, basin, or other water-using equipment, such as a water heater. Alternatively, the outlet of the water supply pipeline 203 passes horizontally through the pre-reserved connection port at the top or bottom of the inspection door module 201, and then passes through the sink mounting hole on the panel 103 to connect directly to the sink, basin, or other water-using equipment 304.

[0135] like Figure 1 , Figure 3 , Figure 8 and Figure 33 As shown, the drainage pipe 204 is arranged horizontally at the bottom of the equipment mezzanine unit 200 or against the wall in the cabinet bottom space of the cabinet unit 100. Its drain outlet connects to the vertically arranged drainage riser 207 inside the equipment mezzanine unit 200, or connects to the existing buried drain outlet / floor drain. The water inlet of the drainage pipe 204 uses a pipe through a bend interface, directly passing through the sink mounting hole opened on the panel 103, or first passing through the communication opening reserved at the top or bottom of the inspection door module 201 and then connecting to the drain outlet of the sink, basin or other water-using equipment.

[0136] like Figure 1 , Figure 3 , Figure 7 and Figure 33 As shown, the gas pipeline 205 is arranged horizontally at the top of the equipment mezzanine unit 200, and its inlet is connected to the gas riser 208 arranged vertically inside the equipment mezzanine unit 200. The gas outlet is connected to the gas stove 303 set on the countertop through a pipe through a bend interface and a connection port reserved at the top of the maintenance door module 201.

[0137] In some of these embodiments, such as Figure 1 , Figure 11 and Figure 19As shown, the power supply line 209 is horizontally arranged in the upper middle part of the equipment mezzanine unit 200 and fixed to the back wall or back panel, and is provided with several switches and sockets for supplying power to various electrical devices.

[0138] In other embodiments, the water supply pipeline 203, drainage pipeline 204, power supply pipeline 209, and gas pipeline 205 within the pipeline module are all exposed pipes, arranged horizontally. Given that most newly built or secondhand houses currently have water and electricity systems embedded in the walls, with fixed interface locations and generally using floor drains, the base plate 101 is actually openable. Figure 11 , Figure 12 , Figure 29 and Figure 33 As shown, the bottom plate 101 of the cabinet unit 100 has an openable structure, with its front end placed on the first support plate 1011 and its rear end placed on the second connector 500.

[0139] For this wall-mounted water and electricity pipe and floor drain design, the water supply pipe 203 is arranged horizontally in the upper middle part of the equipment mezzanine unit 200, and its inlet is connected to the wall-mounted water supply pipe through a bend or tee. The drainage pipe 204 is arranged horizontally at the bottom of the equipment mezzanine unit 200 or against the wall in the cabinet bottom space of the cabinet unit 100, and its drain outlet is connected to the floor drain in the bottom space of the base plate 101 through a pipe.

[0140] In some embodiments, the cabinet unit 100 has a depth of 400-800 mm, and the equipment mezzanine unit 200 has a depth of 100-250 mm. Preferably, the cabinet unit 100 has a depth of 500-700 mm, and the equipment mezzanine unit 200 has a depth of 100-250 mm. More preferably, the cabinet unit 100 has a depth of 600 mm, and the equipment mezzanine unit 200 has a depth of 100-200 mm.

[0141] Furthermore, it is worth noting that, such as Figure 33 As shown, the sustainable functional cabinet with reserved equipment compartment is installed close to the manhole, which contains a water supply riser 206, a drainage riser 207, and a gas riser 208. At least one end of the equipment compartment unit 200 is connected to the manhole for connecting and installing water supply lines 203, drainage lines 204, power supply lines 209, and gas lines 205.

[0142] In some of these embodiments, such as Figure 1 , Figure 2 and Figure 33 As shown, kitchen equipment unit 300 contains various commonly used water, electricity, and gas equipment, which are mainly divided into three categories according to their installation location. Details are as follows:

[0143] The first category consists of devices that can be concealed within the equipment interlayer unit 200. These devices are small in size and can be completely housed within the internal clamping space, or can be installed within the equipment interlayer unit 200 by adjusting the access door module 201. Examples include one or more of the following: water purifier 301, filter 3011, water heater 306, and underfloor heating manifold 307.

[0144] The second category is equipment installed on the panel 103 of the cabinet unit 100. This type of equipment is a regular kitchen appliance that requires manual operation, such as one or more of the following: gas stove 303, sink 304, and washbasin.

[0145] The third category consists of equipment installed in the front cabinet space of cabinet unit 100. This type of equipment is generally large and requires manual operation, and is not suitable for installation on the countertop or within the equipment compartment unit 200. Examples include one or more of the following: dishwasher 302, washing machine 305, and refrigerator.

[0146] Of course, with the continuous development of modern kitchen equipment, there are more and more types of kitchen equipment. Any kitchen equipment can be installed and used in conjunction with the equipment mezzanine unit 200, such as the whole machine being installed in the equipment mezzanine unit 200, or its water and electrical pipes being installed in the equipment mezzanine unit 200.

[0147] like Figure 1 , Figure 2 , Figure 3 and Figure 33 As shown, this sustainable functional cabinet with a reserved equipment mezzanine, through its modular design that reserves space for equipment at the rear, forms a highly adaptable and space-efficient cabinet system. Compared to traditional cabinets, it significantly improves prefabrication efficiency, reduces damage to the cabinet during its lifespan, extends its service life, and completely solves the problems of chaotic installation layouts for diverse equipment, secondary damage to cabinet panels, and wasted space. Simultaneously, it allows for surface connections between each kitchen equipment unit and the building's existing water, electricity, and gas interfaces, eliminating the need for civil engineering modifications, reducing damage to building walls, and making it more environmentally friendly. The flexible arrangement of water, electricity, and gas equipment provides maximum convenience, making the cabinet more sustainable.

[0148] Furthermore, it is worth noting that the sustainable functional cabinet with reserved equipment compartments provided by this invention is not only suitable for kitchens, for the installation of appliances such as dishwashers, water purifiers, and small water heaters, and their pipelines, but can also be applied to bathrooms for the installation of washbasins, water heaters, and their pipelines, or, as needed, for applications such as balconies and dining rooms.

[0149] The specific embodiments of the present invention have been described in detail above, but they are merely examples, and the present invention is not limited to the specific embodiments described above. For those skilled in the art, any equivalent modifications and substitutions to the present invention are also within the scope of the present invention. Therefore, all equivalent transformations and modifications made without departing from the spirit and scope of the present invention should be covered within the scope of the present invention.
