Description

Technical Field

[0001] This utility model belongs to the field of structural technology, and in particular relates to a kitchen counter structure and a motorhome. Background Technology

[0002] RVs, also known as "homes on wheels," combine the living functions of a "house" with the mobility of a "vehicle." They are a type of mobile vehicle equipped with essential home amenities and are popular among travel enthusiasts. A kitchen counter is typically used for storing, washing, and processing food, and is one of the basic amenities that should be considered when equipping an RV.

[0003] However, existing technologies lack kitchen countertops specifically designed for certain types of vehicles (such as RVs). Traditional kitchen countertops are usually designed for ground placement and do not require or have an installation structure to fix the entire traditional countertop to other facilities. If a traditional kitchen countertop is moved into a specific type of vehicle, it is necessary to solve the safety issues such as displacement and tipping of the traditional countertop as the vehicle moves or bumps.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] It should be noted that traditional kitchen countertops in existing technologies generally only have simple washing and storage functions. Most traditional countertops use a wooden frame, with drawers, cabinet doors, and other storage spaces installed or partitioned using mounting accessories. Water trays are installed using glue or silicone sealant. Such traditional countertop structures have low strength and are difficult to install directly onto vehicles (RVs). Furthermore, in the relatively enclosed space of an RV, wood and glue can easily release harmful gases such as formaldehyde into the limited space, making them neither environmentally friendly nor safe. Wooden countertops are also prone to moisture damage and warping, and can breed bacteria, potentially affecting the user's health. Using high-quality wood results in a heavy countertop, unsuitable for use on RVs during travel. Therefore, this embodiment provides a kitchen countertop structure for short-distance RVs, enabling the quick and safe installation of a modular kitchen countertop onto the RV. When not needed, the structure can be easily removed, facilitating the addition and removal of kitchen countertop functions and providing users with more convenient options.

[0018] Based on the above understanding, please refer to Figure 1 , Figure 2 as well as Figure 3 This embodiment provides a kitchen counter structure, including: a base 100, a main frame 200, and a kitchen counter functional module 300. The base 100 has a first mounting structure 110 adapted to be installed on the frame of a target vehicle and a second mounting structure 120 adapted to be installed on the main frame 200. The first mounting structure 110 can be adapted to the mounting structure of at least one type of vehicle frame. For example, in this embodiment, the target vehicle is a motorhome, and the mounting structure of a certain type of motorhome frame is a mounting hole (this mounting hole can be built into the frame itself, or the mounting hole can be opened at a location that does not affect the structural strength of the frame). Therefore, the first mounting structure is a mounting hole adapted to the inner frame of a specific motorhome model, so that the base 100 can be quickly aligned with the specific motorhome model. The mounting holes of the inner frame are then fixed with bolts, allowing the base 100 to be quickly and appropriately fixed into the RV compartment. It should be noted that when the first mounting structure 110 is a mounting hole adapted to the inner frame of a specific RV model, the number and position of these mounting holes can be set according to the mounting holes of that RV model's frame (not shown in the figure). Therefore, there are no limitations on the number or position of the first mounting structure 110. In another embodiment, the first mounting structure 110 may also be a position limiting block, a latch, or other fixing method. Therefore, there are no limitations on the installation method between the first mounting structure and the target vehicle. Figure 2As can be seen, the base 100 in this embodiment has an "L"-shaped side. As a conversion mechanism for the installation interface between the target vehicle and the main frame 200, it only requires mounting holes adapted to different types of vehicles to be made on the base 100. The base 100 can then be adapted to different types of vehicles, while the second mounting structure 120 on the base 100, which is adapted to install the main frame 200, can maintain its original position. This clarifies the mating installation position between the main frame 200 and the base 100, eliminating the need for numerous mounting holes on the main frame 200 to adapt to different types of vehicles, effectively avoiding a reduction in the rigidity, structural stability, and reliability of the main frame 200. For example… Figure 2 As shown, the base 100, which has an "L"-shaped side, has a certain number of second mounting structures 120 (mounting holes) on both its bottom and side surfaces to accommodate the mounting main frame 200. Furthermore, because the base 100 has an "L"-shaped side, when it is fixedly installed inside the vehicle compartment with its side against the compartment wall, the base 100 alone will not occupy excessive interior space. The side of the base 100 also has a cable hole 140 and a water pipe hole 150. The cable hole 140 is used for AC quick-release interfaces and / or DC quick-release interfaces of cables to extend to the outside for power supply, and the water pipe hole 150 is used for quick-release connectors of water pipes (hose) to extend to the outside for water supply.

[0019] In this embodiment, the main frame 200 needs to be adapted and installed with the second mounting structure 120 of the base 100. For example, the second mounting structure 120 of the base can be adapted to the mounting holes 210 of the main frame 200 one-to-one using mounting holes, and then fixed by bolts. Specifically, to ensure quick alignment of the mounting holes between the main frame 200 and the base 100, mounting guide blocks 130 can be provided on the surface of the base 100 (e.g., ...). Figure 2 As shown on the front edge of the main frame 200, a guide groove 220 adapted to the mounting guide block 130 is provided on the bottom front of the main frame 200. In this way, by simply lifting the main frame 200 and making the guide groove 220 on its bottom surface fit the mounting guide block 130 of the base 100, and then letting the guide groove 220 of the main frame 200 slide backward along the mounting guide block 130 to the back against the base 100, all the second mounting structures 120 can be matched one-to-one with the mounting holes 210 of the main frame 200, which is convenient for fixing with bolts. In order to ensure the stability of the bolt connection between the main frame 200 and the base 100, a certain number of mounting holes can be provided on the bottom and side surfaces of the main frame 200 and the base 100, and high-strength bolts can be used for connection and fixing.

[0020] In addition, the kitchen countertop function module 300 in this embodiment can be adapted and installed inside the main frame 200, so that the kitchen countertop function module 300 is not fully exposed on the side of the main frame 200, that is, the kitchen countertop function module 300 is only exposed on the top surface and / or back surface of the main frame 200 according to actual functional needs. Figure 1 As shown in the rear section, a small portion of the structure is exposed to minimize the excessive occupation of the target vehicle (RV) space by the kitchen counter structure while ensuring the functionality of the kitchen counter, thereby improving the space utilization rate of the target vehicle (RV) on which the kitchen counter structure is installed.

[0021] For details, please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 as well as Figure 7 .

[0022] In one possible embodiment, the kitchen countertop functional module 300 of the above-described embodiment includes: a water system structure 310; the water system structure 310 includes: a water inlet, a fresh water tank 311, a faucet 312, a water tray 313, and a grey water tank 314, as shown below. Figure 4As shown; the water inlet (not shown in the figure) is connected to the water inlet of the clean water tank 311 via a water pipe (usually a flexible hose). The water inlet is a quick-release water pipe connector to facilitate the quick addition of tap water, mineral water, or other water sources to the clean water tank 311. The water inlet can be fixed inside the main frame 200 and can be manually extended from the water pipe hole 150 to receive water when needed. In this embodiment, the clean water tank 311 is provided with at least three types of water inlets. The first type of water inlet is a clean water pouring port, located closest to the front of the main frame 200, which facilitates the direct (or funnel-assisted) injection of water into the clean water tank 311 after unscrewing the sealing cap 311a. The second type of water inlet is a pressurized water pouring port, which is connected to a pressure-resistant pressurized water inlet pipe 311b. The other end of the pressurized water inlet pipe 311b is provided with a quick-release water pipe connector for quick access to pressurized water. The three water inlet interfaces are ordinary water pipe pouring ports, which are connected to a flexible ordinary access pipe 311c. The other end of the ordinary access pipe 311c is also equipped with a quick-release water pipe connector for easy and quick connection to tap water. The faucet 312 is connected to the outlet of the clean water tank 311. It can be understood that when the clean water tank 311 is a pressure tank, gas can be drawn into the clean water tank manually or electrically to pressurize it. This allows the connecting pipe of the faucet 312 to be directly connected to the outlet of the clean water tank 311 and inserted into the water. When the water valve 312a of the faucet 312 is opened, the water in the clean water tank 311 can flow into the water pan 313. The drain outlet 313a of the water pan 313 is connected to the inlet 314a of the grey water tank 314 through a water pipe, so that the drain outlet 313a of the water pan 313 can allow the water in the water pan 313 to flow into the grey water tank 314 for storage.

[0023] In addition, such as Figure 1 , Figure 6 as well as Figure 7 As shown, in this embodiment, the water tray 313 of the kitchen countertop structure is embedded in the top surface of the main frame 200, and the faucet 312 is fixedly installed on one side of the water tray 313 (e.g., Figure 1 The water tray 313 shown has a rear edge, and the faucet 312 can be folded into the water tray 313, meaning the faucet 312 has a foldable design so that it can be placed in the water tray 313 when not in use, saving space. In this embodiment, the water tray can be integrally molded with the countertop, reducing water seepage. It can also undergo microcrystalline surface treatment for a better texture and improved user experience.

[0024] In another embodiment, when the clean water tank 311 is not a pressure tank, the water circuit structure of the kitchen countertop structure in this embodiment also includes: a clean water pump 315 and a grey water pump 316; the clean water pump 315 is fixedly installed inside the main frame 200, and the inlet of the clean water pump 315 is connected to the outlet 311d of the clean water tank 311 through a pipe with a filtering function and extends into the clean water tank; the outlet of the clean water pump 315 is connected to the faucet 312 through a water pipe, so that the water in the clean water tank 311 is sent to the faucet 312 through the clean water pump 315, so that when the water valve of the faucet 312 is open and the clean water pump 315 is started, the water in the clean water tank 311 can flow into the water tray 313. Before the water pipe is connected to the inlet of the clean water pump 315, a check valve or flow valve can also be added to the inlet valve. The valve serves to control water flow and prevent backflow, but it is important to ensure that the water flow direction of the valve points towards the pump. Similarly, the ash water pump 316 is fixedly installed inside the main frame 200, and the inlet of the ash water pump 316 is connected to the outlet 314b of the ash water tank 314 via a filter pipe and extends into the ash water tank 314. The outlet of the ash water pump 316 is connected to a water pipe through the water pipe hole 150 and faces outward from the main frame 200, allowing water in the ash water tank 314 to be discharged. The water pipe connected to the outlet of the ash water pump 316 is a flexible hose, which can be stored inside the main frame 200 when not in use. A check valve or flow valve can also be added before the water pipe is connected to the inlet of the ash water pump 316 to control water flow and prevent backflow, but it is important to ensure that the water flow direction of the valve points towards the pump.

[0025] It is understood that the clean water tank 311 in this embodiment is mainly used to store water to be used, and the grey water tank 314 is mainly used to store wastewater that has flowed into the water pan 313 after use. The sealing cap 311a of the clean water pouring port of the clean water tank 311 is tightened and sealed when not in use. When water is injected into the clean water tank 311 using the pressurized water inlet pipe 311b and the through inlet pipe 311c, the clean water tank 311 needs to expel the air in the tank in time to achieve water injection. Therefore, this embodiment needs to set a clean water tank air valve 311e in the clean water tank 311 to expel the air in time when water is injected into the clean water tank 311. When the clean water pump 315 is started to pump water from the clean water tank 311, the clean water tank 311 also needs to draw in air in time through the clean water tank air valve 311e to balance the air pressure inside and outside the clean water tank 311 and achieve water extraction. Similarly, when wastewater from water pan 313 flows into ash water tank 314, to prevent gas in ash water tank 314 from leaking out of drain port 313a of water pan 313 and affecting user experience, this embodiment requires an ash water tank air valve 314c to be installed in ash water tank 314. The ash water tank air valve 314c allows gas to be discharged in time when wastewater flows into ash water tank 314. When ash water pump 316 is started to discharge wastewater from ash water tank 314, ash water tank 314 needs to draw in air in time through ash water tank air valve 314c to balance the air pressure inside and outside ash water tank 314 and achieve wastewater discharge. It should be noted that since the ash water tank air valve 314c will discharge exhaust gas from the ash water tank 314, in order to avoid or reduce the pollution of the water source of the clean water tank 311 by the exhaust gas, the clean water tank air valve 311e and the ash water tank air valve 314c should be set as far apart from each other as possible. Alternatively, within the limited space of the main frame 200, the air valves of the clean water tank air valve 311e and the ash water tank air valve 314c should face opposite directions. It should be noted that the grey water tank 314 needs to be cleaned regularly. The grey water tank 314 can have some reserved interfaces for connecting cleaning fluid, disinfectant or other liquids. These interfaces can be temporarily sealed when not in use. The grey water tank 314 and the clean water tank 311 can also be made of transparent or semi-transparent food-grade materials to facilitate observation of the real-time volume of the liquid inside. When the grey water tank 314 and the clean water tank 311 are made of non-transparent materials such as stainless steel (e.g., food-grade 304 stainless steel), a transparent observation window can be set in the direction facing the front of the main frame 200, or the observation window can be a transparent sealed cover that can be opened to reach in and manually clean the inside of the clean water tank or grey water tank, which can also serve as a manual cleaning function.

[0026] It is understood that the kitchen counter structure of this embodiment may travel to different terrain areas with the target vehicle, which may result in the water tank 311 being in a state of tilt at a certain angle when in use. In order to make the most of the water stored in the water tank 311, this embodiment has a sinking area at the bottom of the water tank 311 that is adapted to the water pump 315. This ensures that the lowest water level in the water tank 311 is still located in the sinking area under the action of gravity and a certain centrifugal force, so as to ensure that the water pump 315 can pump most of the water from the water tank 311 and improve the water level of the water tank 311. 11. Water utilization rate; similarly, in this embodiment, the grey water tank 314 may be in a state of certain tilt angle when discharging wastewater to the outside when the grey water pump 316 is started. In order to empty the wastewater stored in the grey water tank 314 as much as possible, this embodiment can also design a sinking area at the bottom of the grey water tank 314 to adapt to the water pump 316's suction pipe, so that the lowest water level of the wastewater in the grey water tank 314 is located in the sinking area under the action of gravity, so as to ensure that the grey water pump 316 draws up most of the wastewater in the grey water tank 314 and increases the probability of emptying the wastewater in the grey water tank 314. In order to extend the service life of the clean water pump 315 and the grey water pump and avoid or reduce mechanical damage to the clean water pump 315 and the grey water pump, the water pump 315 and the grey water pump have a built-in anti-bottom-slip filter device in the water inlet suction pipe of the water tank.

[0027] In some embodiments, the water circuit structure of the kitchen countertop structure in this embodiment further includes: a first pipeline switching valve and a water heater 318. For example, the first pipeline switching valve can be a multi-channel selectable solenoid valve, a multi-channel selectable manual switching valve, or a pipe tee connector, etc.; the outlet of the clean water pump 315 is connected to the inlet of the first pipeline switching valve, and the first pipeline switching valve has one inlet and at least two outlets (e.g., a pipe tee connector 317). The faucet 312 in this embodiment has a hot water inlet and a cold water inlet, and can be connected to a water heater. Different rotation angles of the valve allow for the mixing and output of cold and hot water in varying proportions. The inlet 318a of the water heater 318 is connected to the first outlet of the first pipeline switching valve, enabling the water heater 318 to receive cold water input from the clean water pump 315. The outlet 318b of the water heater 318 is connected to the hot water inlet of the faucet 312, allowing hot water access to the faucet 312. The second outlet of the first pipeline switching valve is connected to the cold water inlet of the faucet 312, allowing cold water access to the faucet 312. It should be noted that the kitchen counter structure in this embodiment supports the connection of a certain number of pipe tees, pipe two-way connectors, pipe four-way connectors, etc., to the water pipes output from the clean water pump 315. This allows users to expand the use of other water-using appliances or equipment according to actual needs. Only the connections of temporarily unused pipe tees, pipe two-way connectors, pipe four-way connectors, etc., need to be sealed, facilitating expansion.

[0028] In another embodiment, to ensure that the cold water flowing from the faucet 312 meets the requirements for direct drinking, the water circuit structure of the kitchen counter structure in this embodiment also includes: a water dispenser 319; the water inlet of the water dispenser 319 is connected to the second water outlet of the first pipeline switching valve, so that the water dispenser 319 can be connected to the water source, and the user can directly get water to drink at the water outlet of the water dispenser 319. The user only needs to open the door of the main frame 200 to start the water dispenser 319 to get water to drink. Alternatively, in another embodiment, to enable the water dispenser 319 to supply drinking water at the faucet 312, the inlet of the water dispenser 319 is connected to the second outlet of the first pipeline switching valve, so that the water dispenser 319 is connected to a water source. The outlet of the water dispenser 319 is connected to the cold water inlet of the faucet 312, so that when the faucet 312 opens the cold water switch and the water dispenser 319 starts dispensing water, the water flowing out meets the requirements for direct drinking. Alternatively, in another implementation, to ensure that both the water source for the clean water tank 311 and the drinking water for the water dispenser 319 can be supplied from the tap 312, in this embodiment, the water inlet of the water dispenser 319 is connected to or the third outlet of the first pipeline switching valve (for example, in this embodiment, the first pipeline switching valve is a four-way pipe connector, two combined three-way pipe connectors, etc.); the second pipeline switching valve used in this implementation has at least two inlets and one outlet (for example, a three-channel solenoid valve with one input connected to the outlet, a three-channel...). (Input selection: a manual switching valve or pipe tee connector, etc., connected to the water outlet) The water outlet of water dispenser 319 is connected to the cold water inlet of faucet 312 via a second pipeline switching valve, including: the outlet of the second pipeline switching valve is connected to the cold water inlet of faucet 312, and the first inlet pipe of the second pipeline switching valve is connected to the second outlet of the first pipeline switching valve, so that water from clean water tank 311 enters the cold water inlet of faucet after passing through the first and second pipeline switching valves. The second inlet pipe of the second pipeline switching valve... The water pipe is connected to the outlet of the water dispenser 319. When the second pipeline switching valve is a solenoid valve with one of the three inputs connected to the outlet or a manual switching valve with one of the three inputs connected to the outlet, the water from the water dispenser 319 is output as drinking water through the faucet 312. This requires turning on the cold water switch of the faucet 312 and switching the second pipeline switching valve to the pipeline channel connecting to the water dispenser 319 to start the water dispenser 319 and output drinking water. Water from the clean water tank 311 is output through the faucet 312, which also requires turning on the faucet. Turn on the cold water switch of faucet 312 and switch the second pipeline switching valve to connect to the pipeline channel of clean water tank 311, and start the clean water pump 315 to output water from clean water tank 311; when the second pipeline switching valve is a pipeline tee, if the water dispenser 319 outputs drinking water and the clean water pump 315 outputs water from clean water tank 311 when the cold water switch of faucet 312 is turned on, the water dispenser and the clean water pump should be set not to work at the same time to avoid mixing of the water output from the water dispenser and the clean water tank, which would cause waste. Please see Figure 5 The kitchen countertop functional module of this embodiment also includes: an electrical wiring structure 320; the electrical wiring structure 320 includes: an AC wiring harness, an AC conduit, a DC wiring harness, a DC conduit, an AC fuse box, a DC inverter fuse box, and an output junction box; wherein the input end of the AC wiring harness has a first quick-release interface, which is used to connect AC power (such as mains power or vehicle AC power) from the outside; the other end of the AC wiring harness passes through the AC conduit and is connected to the AC fuse box, and then the AC wiring harness is connected to the output junction box through the AC fuse box; the AC conduit is usually insulated. Made of insulating material and fixed within the main frame 200, it guides and protects the AC wiring harness, preventing or reducing damage to the AC wiring harness or direct contact with the main frame 200, ensuring the safety of AC power supply. The AC fuse box contains a safety circuit to ensure the safety of AC power supply to the kitchen counter. The output junction box contains voltage and current stabilization circuits to provide suitable operating voltage and current for the electrical equipment in the kitchen counter structure of this embodiment (such as the clean water pump, grey water pump, water heater, water dispenser, etc.). All electrical equipment can draw power from the output junction box. Similarly, the input end of the DC harness has a second quick-release interface for connecting DC power from the outside (e.g., outdoor power bank or vehicle DC power supply). The other end of the DC harness passes through a DC conduit and connects to the DC inverter fuse box. The DC conduit is usually made of insulating material and is fixed inside the main frame 200 to guide and protect the DC harness, preventing or reducing damage to the DC harness or direct contact with the main frame 200, ensuring the safety of the DC power connection. Since most of the electrical equipment in this embodiment is AC electrical equipment, it needs to be connected to the DC inverter. The inverter circuit in the inverter fuse box converts DC power into suitable AC power, and then the AC wiring harness is connected to the output junction box via the DC inverter fuse box. In this embodiment, the output junction box can provide suitable AC power and DC power with suitable operating voltage. It is only necessary to equip the output junction box with the corresponding conversion circuit. It should be noted that in this embodiment, the second target connector adapted to the second quick-release interface cannot be adapted to the first quick-release interface, and the first target connector adapted to the first quick-release interface cannot be adapted to the second quick-release interface. This serves as a foolproof function to avoid incorrect insertion when AC and DC power are input. Of course, it is understandable that, in order to increase the safety of electricity use, the electrical circuit structure 320 of this embodiment may also include: a ground wire and a grounding conduit. One end of the ground wire is used to install on the common grounding terminal of the vehicle or is designed to be easily inserted into the ground. The other end of the ground wire passes through the grounding conduit and is connected to the electrical equipment or grounding location that needs to be grounded. The grounding conduit is also made of insulating material and is fixed inside the main frame 200 to guide and protect the grounding cable, avoid or reduce damage to the ground wire or direct contact with the main frame 200, and ensure the safety of the grounding cable.

[0029] For further details, please refer to Figure 6 The electrical circuit structure 320 in this embodiment also includes: a clean water pump switch 321, a grey water pump switch 322, a screen display switch 323, and a display screen 324. The input terminal of the clean water pump switch 321 is connected to the output junction box via a cable to obtain power, and the output terminal of the clean water pump switch is connected to the clean water pump via a cable, enabling the clean water pump to be powered on and off by controlling the output junction box through the clean water pump switch. The input terminal of the grey water pump switch 322 is connected to the output junction box via a cable to obtain power, and the output terminal of the grey water pump switch is connected to the grey water pump via a cable, enabling the clean water pump to be powered on and off by controlling the output junction box through the clean water pump switch. The grey water pump switch controls the power supply to the grey water pump via the output junction box, enabling power-on and power-off shutdown. The display screen 324 draws power from the output junction box via a cable. The display screen can be wired or wirelessly connected to one or more of the following: grey water pump, clean water pump, clean water tank level sensor (if present), grey water tank level sensor (if present), water dispenser, and water heater, displaying corresponding status information. This allows users to monitor the water levels in the clean water and grey water tanks in real time, monitor and adjust the water temperature of the water heater, and discharge wastewater from the grey water tank with a single button. The display screen 324 can be one screen or multiple screens. For example, in this embodiment, two screens are used to display the operating status information of the clean water pump and grey water pump respectively. The number and installation location of the screens can be set according to actual needs. The screen display switch 323 controls the display screen 324 to turn on or off, saving energy and reducing the impact of the display screen on people while sleeping or resting.

[0030] Furthermore, in this embodiment, the main frame 200 of the kitchen countertop structure has at least one storage space, such as a drawer 230 or a storage compartment 240. This storage space is used to place cooking heating equipment such as an induction cooker 400, a portable gas stove, or an open flame stove. The top surface of the main frame 200 has a flat countertop area 250, which can be used to place the cooking heating equipment such as the induction cooker, portable gas stove, or open flame stove placed in the storage space for cooking. The electrical wiring structure 320 also includes a socket 325. The socket 325 is connected to an output junction box via an AC wiring harness to obtain power (e.g., 220V / 50Hz) to provide mains power and allow users to connect various conventional electrical devices.

[0031] For details, please refer to Figure 2 , Figure 3 , Figure 6 as well as Figure 7In this embodiment, the main frame 200 of the kitchen countertop structure is made of high-strength aluminum-magnesium alloy. Reinforcing ribs 260 are used for support and fixation at various connection points of the main frame 200 to enhance its structural stability. The main frame can be roughly divided into three parts: upper, middle, and lower. A drawer 230 is located on the front left side of the upper layer, and the top surface of the upper layer (directly above the drawer) is a flat countertop area 250. An operation panel 326 is located on the front right side of the upper layer. The operation panel 326 integrates the clean water pump switch 321, the grey water pump switch 322, the screen display switch 323, the display screen 324, and the socket 325, saving space. A water tray 313 is recessed on the top right side of the upper layer. Of course, in practical applications, the arrangement of the left and right sides of the upper layer can be interchanged, and is not limited here. The middle layer of the main frame 200 is used to house the water dispenser 319, water heater 318, clean water pump 315, and grey water pump 316. Preferably, the water dispenser 319 and water heater 318 are arranged below the upper drawer 230 on the middle layer of the main frame 200, and the clean water pump 315 and grey water pump 316 are arranged below the upper water tray 313 on the middle layer of the main frame 200, in order to save water pipe materials and reduce the weight of the overall kitchen counter structure. The lower layer of the main frame 200 is used to house the clean water tank 311 and grey water tank 314. Preferably, the grey water tank 314 is located below the upper water tray 313 to facilitate direct access to wastewater flowing down from the water tray 314. In this embodiment, the clean water tank 311 is relatively heavy when full of water, so placing it on the bottom layer helps to lower the center of gravity of the kitchen counter structure, making the kitchen counter structure more stable. Of course, the equipment arranged in the middle and lower layers of the main frame 200 of the kitchen counter structure in this embodiment can be replaced according to actual needs, and there is no limitation here. Specifically, the main frame of this embodiment provides installation positions for the equipment of each kitchen counter functional module 320. For example, for the installation of drawers 230, a slide rail installation space for drawer slide rail installation is pre-set on the upper layer of the main frame 200; for the installation of water trays 313, a recessed frame for water tray size is pre-set on the upper layer of the main frame 200; and the middle layer below the water tray 313 facilitates the installation of clean water pumps 311, grey water pumps 314, water heaters 318, and water dispensers 319, while also considering the installation of clean water pumps 311 and grey water pumps 314. For convenient maintenance of the water pump 314, water heater 318, and water dispenser 319, a tray 270 is used for support and installation, and the tray 270 is then installed on the middle support of the main frame 200. The clean water tank 311 and grey water tank 314 are placed on the lower layer of the main frame 200. Since the clean water tank 311 and grey water tank 314 are relatively heavy, limiting blocks or other methods can be used to restrict their displacement. To give the kitchen countertop structure of this embodiment a style that conforms to traditional impressions, decorative panels can also be installed on various surfaces of the main frame 200, such as... Figure 1As shown, a double-leaf cabinet door 280 is provided on the front of the main frame, and the cabinet door 280 is installed to the main frame 200 via hinges 500. The device panel in this embodiment can be replaced by sheet metal, plastic, wood, and composite materials, but the surface of the decorative panel should be made of antibacterial material to effectively prevent bacterial growth and protect the user's health; however, no limitation is imposed here.
