Description

Technical Field

[0001] This utility model relates to the field of washbasin cabinet technology, specifically to a marine washbasin cabinet based on waste heat recovery. Background Technology

[0002] On ships, washbasin cabinets, commonly known as "washbasin cabinets" or "lavatories," are indispensable and practical facilities in passenger cabin lavatories. Cleverly integrated into limited space, they form a simple washing area together with the washbasin and mirror. Their design prioritizes the unique environment of a ship, therefore they generally feature sturdy fixing devices to withstand the ship's rolling and ensure navigational safety. The cabinets are mostly made of moisture-proof and corrosion-resistant composite materials, effectively resisting the humidity and moisture in the lavatory and extending their lifespan. Functionally, they not only support the washbasin but also provide valuable storage space. Passengers can neatly store toiletries, washbasins, towels, and other personal items inside, keeping the lavatory clean and dry, which is especially important in the already cramped space of a ship's cabin.

[0003] Application publication number CN118928661A discloses a marine washbasin rack. According to its instruction manual and accompanying drawings, the design features drainage holes on the third outer flap, allowing water flowing from the basin to drain promptly and preventing the accumulation of bacteria and grime on the flap over time. Furthermore, to further prevent water droplets from accumulating around the drainage holes, the third outer flap also includes guide grooves that connect to the drainage holes, allowing water droplets around the holes to flow through and drain out.

[0004] However, this solution has certain limitations: 1. The core of this solution is "drainage" rather than "drying." It only has drainage holes and guide grooves on the third outer flap at the bottom, which can only drain most of the surface water in the basin. However, in the high humidity and high salinity of the marine climate of a ship, the moisture remaining on the inner wall, bottom, and in the gaps where it contacts the limiting components cannot be quickly removed by natural evaporation; 2. This solution utilizes airflow and temperature within the cabin for drying, which is very inefficient in reality; ship cabins often have limited ventilation, especially in severe sea conditions when doors and windows need to be closed, and the internal humidity may even be higher than the external humidity. Summary of the Invention

[0005] This utility model mainly addresses the problems existing in the use of marine washbasin cabinets. It has invented a marine washbasin cabinet based on waste heat recovery, which uses the waste heat of the ship for active drying and has good ventilation and safe storage functions, thus avoiding the phenomenon of dampness and mold on the toiletries on the ship.

[0006] The purpose of this invention is achieved through the following technical solution: a shipboard washbasin cabinet based on waste heat recovery, comprising a cabinet body, the interior of which is provided with several storage partitions for storing items, the cabinet body including an open side and also provided with several storage doors for sealing the open side, each cabinet body also being provided with a guide pipe, the inlet and outlet of the guide pipe being connected in parallel to any pipe on the ship that has hot water flowing inside.

[0007] Preferably, each of the flow channels can be fitted to the lower surface of the storage partition, and the flow channels are arranged in a U-shape when passing through the lower surface of the storage partition.

[0008] Preferably, each of the storage compartments has an annular protrusion at its bottom, and each annular protrusion has a clearance hole inside that allows the guide pipe to pass through; the annular protrusion and the clearance hole inside it provide positioning and mounting slots for the guide pipe; ensuring that the pipe can be accurately and firmly fitted into the preset position during installation.

[0009] Preferably, the cabinet body has a number of supporting profiles inside, each of the storage partitions is disposed on the surface of the supporting profiles, and each of the storage partitions has a number of first ventilation holes and a number of grooves on its surface.

[0010] Preferably, the top surface of the cabinet body is provided with ventilation holes, the bottom of the cabinet body is provided with a rectangular through hole and a ventilation partition is provided above the rectangular through hole, and the surface of the ventilation partition is provided with a plurality of second ventilation holes.

[0011] Preferably, each of the storage doors includes a metal hinge, a first door panel, and a second door panel nested inside the first door panel. The first door panel and the second door panel are fixedly connected by welding. One end of the metal hinge is connected to the second door panel. The second door panel is provided with a hinge clearance groove for avoiding the protrusion at the end of the metal hinge. The other end of the metal hinge is connected to the interior of the cabinet body. The surface of the first door panel is also provided with a nameplate frame for installing a nameplate and a handle. The hinge clearance groove design in this configuration allows the protruding part of the metal hinge to be embedded inside the second door panel, achieving a flat connection between the hinge and the door panel; this makes the appearance cleaner and allows the cabinet structure to be designed more compactly.

[0012] Preferably, the first door panel and the second door panel are provided with lock cylinder mounting holes, the lock cylinder mounting holes are provided with mechanical knob locks, and the cabinet body is provided with several lock tongue limiting grooves adapted to the lock tongue of the mechanical knob lock. When the lock tongue of the mechanical knob lock is in the extended state, it can be locked inside the lock tongue limiting groove. This design provides an independent locking function for each storage door; the combination of mechanical knob locks and latch limit slots effectively prevents others from opening the cabinet doors at will in the complex environment of a ship, ensuring the privacy and security of crew members' personal belongings.

[0013] Preferably, the bottom of the cabinet body is also provided with several raised profiles, and each of the raised profiles is provided with a foot pad at the bottom; this setting lifts the entire cabinet body off the deck or ground, ensuring that the air intake channel of the bottom through hole is unobstructed and forming an effective air circulation.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The diversion pipeline is connected in parallel to the internal pipelines of the ship that carry hot water (such as kitchen water or engine cylinder liner cooling water), and uses the waste heat generated during the operation of the ship for heat exchange; this realizes waste heat recovery, eliminating the need for additional electricity or fuel to generate heat, and significantly reducing the ship's operating energy consumption (such as avoiding the use of electric heating wires or drying fans); at the same time, this solution converts the heat energy that would otherwise be lost to the environment into useful drying energy, improving energy utilization efficiency; 2. The drainage pipes are attached to the lower surface of the storage shelf and arranged in a U-shape to maximize the heat contact area and improve heat exchange efficiency. By continuously and gently heating the storage shelf, a low-temperature drying environment is created inside the cabinet, which can actively and quickly evaporate residual moisture on the basin or toiletries, keeping the items dry. 3. The surface of the storage shelf is provided with several first ventilation holes and grooves, the top of the cabinet body is provided with ventilation holes, and the bottom is provided with rectangular through holes and ventilation partitions; these ventilation holes and through holes promote the flow of air inside the cabinet body, allowing water vapor or water droplets to fall downwards through the first ventilation holes or grooves, keeping the items on the surface of the storage shelf dry; at the same time, the ventilation holes connect the inside of the cabinet body with the outside, which helps to dissipate odors and keep the washbasin cabinet clean and tidy.

Detailed Implementation

[0018] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings: like Figure 1 and Figure 2 As shown, a shipboard washbasin cabinet based on waste heat recovery includes a cabinet body 1. The cabinet body 1 has several storage partitions 2 for storing items inside. The cabinet body 1 includes an open side and also has several storage doors 3 for sealing the open side.

[0019] During implementation, the cabinet body 1 is integrated and installed in a designated area on the ship. The storage doors 3 are detachably connected to each cabinet body 1. The open side of the cabinet body 1 is in an open state, with the storage door 3 not closed on any storage shelf 2 side of the open side. Users can neatly store personal items such as washbasins, toiletries, and towels on the surface of the storage shelf 2 inside the cabinet body 1. Then, the storage door 3 is closed again. The items on the surface of the storage shelf 2 are restrained by the inner wall of the cabinet body 1 and the side wall of the storage door 3, so even if the ship shakes significantly, the items will not fall out of the cabinet body 1.

[0020] Please refer to the reference. Figure 2 and Figure 6 The cabinet body 1 has several supporting profiles 11 inside, and each storage partition 2 is provided on the surface of the supporting profile 11. Each storage partition 2 has several first ventilation holes 22 and several grooves 23 on its surface.

[0021] With this arrangement, the support profiles 11 are arranged side by side, and the contact area between the support profiles 11 and the bottom of the storage partition 2 is small, thus enabling the storage partition 2 to have better ventilation in humid conditions. Since each storage partition 2 is not a uniform rectangle or square, the design of the first ventilation hole 22 and the presence of several slots 23 allows air to flow downwards from the top of the storage partition 2. Simultaneously, moisture or water droplets on the surface of the storage partition 2 can fall downwards through the gaps in the first ventilation hole 22 or the slots 23, keeping the items on the surface of each storage partition 2 as dry as possible.

[0022] Please continue to refer to this. Figure 2 and Figure 4 The top surface of the cabinet body 1 is provided with ventilation holes 13. The bottom interior of the cabinet body 1 is provided with a rectangular through hole 12, and a ventilation partition 5 is provided above the rectangular through hole 12. The surface of the ventilation partition 5 is provided with several second ventilation holes 51. The bottom of the cabinet body 1 is also provided with several raised profiles 14, and each raised profile 14 is provided with a foot pad 15 at its bottom.

[0023] The ventilation hole 13 serves to connect the interior and exterior of the cabinet body 1, allowing items inside the cabinet body 1 to dry quickly under the influence of flowing air. At the same time, the ventilation hole 13 also helps to disperse odors inside the cabinet body 1, keeping the entire washbasin cabinet clean and tidy.

[0024] Please refer to the reference. Figure 2 and Figure 5 Each of the storage doors 3 includes a metal hinge 6, a first door panel 31, and a second door panel 32 nested inside the first door panel 31. The first door panel 31 and the second door panel 32 are fixedly connected by welding. One end of the metal hinge 6 is connected to the second door panel 32. The second door panel 32 is provided with a hinge clearance groove 321 for avoiding the protruding part at the end of the metal hinge 6. The other end of the metal hinge 6 is connected to the interior of the cabinet body 1. The surface of the first door panel 31 is also provided with a nameplate frame 311 for installing a nameplate and a handle 312.

[0025] During implementation, the first door panel 31 and the second door panel 32 are welded together to form a single unit, which is hollow inside. This design achieves weight reduction and facilitates the installation of the metal hinge 6 and the mechanical knob lock 34. The hinge clearance groove 321 is designed so that the protruding part at the end of the metal hinge 6 is recessed inside the hinge clearance groove 321, reducing the space occupied when the end of the metal hinge 6 is connected to the second door panel 32.

[0026] Different nameplates can be placed inside the nameplate frame 311 to distinguish which person owns the items on the surface of each storage compartment 2. Since the two ends of each metal hinge 6 are connected to the inside of the second door panel 32 and the inside of the cabinet body 1 respectively, the metal hinge 6 can be fully hinged when the entire first door panel 31 and the second door panel 32 are opened or closed, thereby changing the angle of the surface of the storage door 3 relative to the cabinet body 1, and playing a supporting and guiding role.

[0027] Due to the diverse crew on board, to further prevent theft of items from the surface of the storage partition 2, the first door panel 31 and the second door panel 32 are provided with lock cylinder mounting holes 33. The lock cylinder mounting holes 33 are equipped with mechanical knob locks 34, and the cabinet body 1 is equipped with several lock tongue limiting grooves 10 that are adapted to the lock tongue of the mechanical knob locks 34.

[0028] During implementation, when the bolt of the mechanical rotary lock 34 is in the extended state, it can be locked inside the bolt limiting groove 10; when the bolt of the mechanical rotary lock 34 is in the retracted state, it can disengage from the bolt limiting groove 10. Each mechanical rotary lock 34 uses a non-interchangeable key; therefore, only the corresponding user can turn the bolt of the mechanical rotary lock 34 with the correct key, thereby achieving the individual locking and unlocking functions for each storage door 3.

[0029] Please continue to refer to this. Figure 3 Each cabinet body 1 is also equipped with a flow guide pipe 4, the inlet and outlet of which are connected in parallel to any internal hot water pipe on the ship. Specifically: the flow guide pipe 4 can be connected in parallel to the ship's kitchen water supply; the ship's kitchen requires a large amount of hot water for washing dishes, washing vegetables, cooking, etc. The flow guide pipe 4 can also be connected in parallel to the engine cylinder liner cooling water: the ship's engine generates a large amount of heat during operation, which needs to be cooled by cooling water (cylinder liner water); the temperature of this water is usually kept at a warm level.

[0030] It should be noted that the water in the diversion pipe 4 does not come into contact with the storage partition 2. Some heat will be lost from the diversion pipe 4 to the storage partition 2. In addition, the storage partition 2 is in a ventilated state, so the storage partition 2 is warm and will not be hot to the touch.

[0031] After the diversion pipe 4 is connected in parallel to any other pipe, a solenoid valve for controlling the water circuit switch and a water temperature sensor need to be installed at the inlet connection point of the diversion pipe 4. The water temperature sensor monitors water temperature changes, and when the water temperature exceeds 50 degrees Celsius or 60 degrees Celsius, the solenoid valve closes the inlet of the diversion pipe 4. After a period of time, the solenoid valve reopens the inlet of the diversion pipe 4.

[0032] Specifically, each of the flow guide pipes 4 can fit against the lower surface of the storage partition 2. The flow guide pipes 4 are arranged in a U-shape when passing through the lower surface of the storage partition 2. This arrangement can maximize the heat exchange effect between the flow guide pipes 4 and the storage partition 2. Each storage partition 2 has an annular protrusion 21 at its bottom, and each annular protrusion 21 has a clearance hole inside to allow the flow guide pipes 4 to pass through.

[0033] With this setup, the warm water flowing through the guide pipe 4 continuously and gently heats each storage compartment 2 of the washbasin cabinet, creating a low-temperature drying environment. This actively and quickly evaporates residual moisture from the washbasin or toiletries, keeping them dry. This dry environment is optimal for preventing microbial growth, improving the overall hygiene of the washbasin cabinet and protecting the health of the crew.

[0034] This solution utilizes a waste heat recovery or utilization technology. The hot water flowing within the guide pipe 4 does not consume additional energy to generate heat, cleverly utilizing the heat energy carried by the hot water during its transport, which would otherwise be used elsewhere. It eliminates the need for separate electric heating wires, drying fans, and other energy-consuming equipment for the washbasin cabinet, reducing the ship's operational electricity consumption. It improves energy efficiency by converting heat loss from the piping into useful drying energy, achieving the reuse of "waste heat" and aligning with the environmental protection concept of green ships. This solution only requires integrating water piping within the existing washbasin cabinet and connecting it to the ship's existing hot water system, eliminating the need for complex and expensive additional heating devices. The structure is simple, with the main cost being in piping and installation, far lower than a standalone drying system. The drying function is automatically completed while providing hot water, requiring no additional operation from the crew.

[0035] Working principle and usage of this utility model: The flow guide pipe 4, integrated within the cabinet body 1, has its inlet and outlet connected in series to the ship's galley hot water pipe or engine cylinder liner cooling water pipe. This allows hot water at a temperature of 70-85℃ to continuously flow through the flow guide pipe 4.

[0036] The heat transfer pipe 4 is tightly fitted to the lower surface of the storage partition 2 in a U-shaped layout, efficiently transferring heat to the storage partition 2. The heated storage partition 2 continuously and evenly heats items such as basins and towels placed on its surface, accelerating the evaporation of surface moisture and achieving rapid drying.

[0037] The first ventilation holes 22 and grooves 23 on the surface of the storage partition 2 not only reduce weight, but more importantly, provide channels for the vertical flow of air and moisture. Evaporated water vapor can flow downwards through these holes.

[0038] The ventilation holes 13 at the top and the rectangular through holes 12 at the bottom of the cabinet body 1 together form a ventilation system. Hot air inside the cabinet carrying moisture is discharged from the top ventilation holes 13, while the drier, cooler air outside enters from the bottom rectangular through holes 12 (and diffuses evenly through the second ventilation through holes 51 of the ventilation partition 5).

[0039] The raised base 14 and feet 15 ensure sufficient space at the bottom of the cabinet, guaranteeing smooth airflow. When the storage door 3 is closed, the inner wall of the cabinet body 1 and the side wall of the storage door 3 together form a closed space, effectively limiting the items. Even when the ship is rocking, items will not easily tip over or fall off.

[0040] The bolt of the mechanical knob lock 34 can extend into the bolt limiting groove 10 to securely lock the storage door 3 and ensure the safety of the items.

[0041] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
