Technical Field
[0001] This utility model relates to the field of kitchen technology, specifically to a kitchen emergency drainage device. Background Technology
[0002] Kitchen emergency drainage devices are devices specifically designed for kitchens to handle sudden leaks and other accidents, promptly draining accumulated water to prevent damage to kitchen facilities and building structures. Floor drains are a common type of kitchen emergency drainage device. Floor drains are usually installed at the lowest point of the kitchen floor to ensure that water flows naturally to the floor drain, collects leaked water in a timely manner, and drains it away through drainage pipes to prevent cabinets from getting damp and damaged.
[0003] However, to prevent air pollution from spreading between floors through drainage pipes, kitchen floors are usually not equipped with floor drains. If the kitchen water pipes are old and neglected, the connecting hoses between the water pipes and faucets will harden and crack easily if they are not replaced in time. Because the water pressure inside the pipes is high, once a leak occurs, the damaged area will expand rapidly under the pressure. The water cannot be drained through the floor drain in time and will spread to other rooms such as the dining room, living room, and bedroom, causing water to soak the floors, furniture, and walls.
[0004] In view of this, we propose a kitchen emergency drainage device. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0026] If the water cannot be drained in time through the floor drain, it will spread to other rooms such as the dining room, living room, and bedroom, causing water to soak the floors, furniture, and walls, resulting in property damage and increasing the difficulty of repair and cleaning.
[0027] like Figures 1-4As shown, this embodiment provides a kitchen emergency drainage device, including a wall 1 and a cabinet 2. A waterproof structure 5 is fixedly connected to the bottom of the inner side of the cabinet 2, and a drainage component 4 is fixedly connected to the center of the bottom of the inner side of the cabinet 2. The drainage component 4 includes an emergency drainage pipe connector 41, with a fastening bolt 43 spirally connected to the inner side of the emergency drainage pipe connector 41. The emergency drainage pipe connector 41 is fixedly connected to the bottom of the inner side of the cabinet 2 by the fastening bolt 43. An emergency drainage pipe body 44 is sleeved on the inner side of the emergency drainage pipe connector 41 by sealing with a sealing material. One end of the emergency drainage pipe body 44 passes through the bottom plate of the inner side of the emergency drainage pipe connector 44 and the wall 1. An external wall decorative cover ring 45 is installed at the part of the emergency drainage pipe body 41 that passes through the wall 1. A guide rod 46 is fixedly connected to the upper end of the emergency drainage pipe connector 41, and a movable protective cover plate 47 is provided at the lower end of the emergency drainage pipe connector 41. The movable protective cover plate 47 is slidably connected to the outer side of the guide rod 46.
[0028] When a water pipe bursts or a faucet is not turned off in the kitchen, water will flow to the bottom inside of the cabinet 2. The waterproof structure 5 around the bottom inside of the cabinet 2 prevents the water from flowing out. The water accumulates inside the cabinet. As the water volume increases, the water will reach the drainage component 4. The movable protective cover 47 will slide upward and open along the guide rod 46, which is fixedly connected to the upper end of the emergency drain pipe joint 41, under the action of buoyancy or water flow impact. Water will flow through the emergency drain pipe joint 41 into the emergency drain pipe body 44, which is sealed and fitted inside by the sealing material. The emergency drain pipe body 44 passes through the wall 1 and leads to the outside. It uses a 2% outward slope to drain the water to the outside. After the drainage is completed, the movable protective cover 47 will slide down and reset along the guide rod 46 under the action of gravity, sealing the lower end of the emergency drain pipe joint 41.
[0029] like Figure 1-4As shown, a cabinet 2 is fixedly connected to one side of wall 1, and a faucet 3 is fixedly connected to the top of cabinet 3. The waterproof structure 5 is turned up 50mm on all four sides. A reserved opening is provided in the middle of the inner bottom plate of cabinet 2. A waterproof sealing gasket 42 is provided between the lower end of the emergency drain pipe connector 41 and the reserved opening in the inner bottom plate of cabinet 2. The emergency drain pipe connector 41 passes downward through the waterproof sealing gasket 42 and the reserved opening in the inner bottom plate of cabinet 2. The main body of the emergency drain pipe 44 passes through wall 1 and the exterior wall decorative cover ring 45 to the outside. One end of the main body of the emergency drain pipe 44 slopes outward by 2%. The exterior wall decorative cover ring 45 is fixedly connected to the inner side of wall 1 by sealing with waterproof sealing material. In the event of a leak in the kitchen, water will accumulate on the inner bottom plate of cabinet 2. The waterproof structure 5 is turned up 50mm around the perimeter to prevent the water from overflowing to the outside of cabinet 2. The water flows through the pre-drilled hole in the middle of the inner bottom plate of cabinet 2 and into the main body of the emergency drain pipe 44 through the emergency drain pipe joint 41. The waterproof sealing gasket 42 fills the gap between the emergency drain pipe joint 41 and the pre-drilled hole in the inner bottom plate of cabinet 2 to prevent water from leaking from the connection. The main body of the emergency drain pipe 44 slopes outward by 2% to allow the water to flow to the outside by gravity. The exterior wall decorative cover ring 45 is fixedly connected to the inside of the wall 1 with waterproof sealing material to seal the gap between the pipe and the wall 1 and prevent outdoor water from flowing back in and indoor water from seeping out.
[0030] like Figures 4-5 As shown, the movable protective cover 47 includes a cover plate 471, a guide ring 472 fixedly connected to the outer side of the cover plate 471, and four guide rods 46. The four guide rods 46 are arranged in a circular array around the vertical line of the upper end of the waterproof sealing gasket 42 as the axis. The guide rods 46 are T-shaped. The lower ends of the guide rods 46 are all perpendicular to the upper end of the emergency drain pipe joint 41. There are four guide rods 46 in total, arranged in a circular array around the vertical line of the upper end of the waterproof sealing gasket 42 as the axis, and vertically fixed to the upper end of the emergency drain pipe joint 41 in a T-shape. When the water inside the cabinet reaches a certain amount, the buoyancy or water flow impact force acts on the movable protective cover 47. The guide ring 472 on the movable protective cover 47 is sleeved on the outside of the guide rod 46. When subjected to force, it slides along the guide rod 46, causing the cover 471 to move upward, opening the drainage channel. After drainage is completed, the movable protective cover 47 slides down along the guide rod 46 to reset under the action of gravity. The guide rod 46 provides guidance for the opening and closing of the movable protective cover 47, ensuring that it does not deviate or shake during the up and down movement, and is stable and reliable.
[0031] like Figure 5As shown, four guide rings 472 are provided, and straight holes are provided on the inner side of the four guide rings 472. The inner side of the straight hole of the guide ring 472 is slidably connected to the outer side of the guide rod 46. The number of guide rings 472 corresponds to the number of guide rods 46. The straight hole on the inner side of the guide ring 472 cooperates with the outer side of the guide rod 46 to achieve a sliding connection. When the movable protective cover 47 is subjected to force, the guide ring 472 slides along the guide rod 46, driving the entire movable protective cover 47 to move, ensuring the smooth sliding of the movable protective cover 47, ensuring the normal operation of the drainage device, extending the service life of the drainage pipe, and reducing maintenance costs.
[0032] In summary, the working principle of this solution is as follows: A cabinet 2 is fixed to one side of wall 1. A faucet 3 is installed on the top of cabinet 2. A waterproof structure 5 extends 50mm up around the bottom of the inside of cabinet 2 to prevent water leakage to the outside. A movable protective cover 47, under its own weight and guided by a guide rod 46, covers the lower end of the emergency drain pipe joint 41, keeping it closed. A waterproof sealing gasket 42 is installed between the cover and the pre-drilled opening in the base plate to ensure a sealed connection and prevent external wind, rain, and insects from entering. When a leak occurs in the kitchen faucet 3 or water pipe, water accumulates at the bottom of the inside of cabinet 2 and flows towards the emergency drain pipe joint 41. As the water volume increases, the water level rises. When the accumulated water reaches a certain amount but does not exceed the height of the waterproof structure 5, the water level drops. The buoyancy or water flow impact force generated causes the cover plate 471 and guide ring 472 of the movable protective cover plate 47 to overcome their own weight and slide upward along the guide rod 46 to open. At this time, water flows into the main body of the emergency drain pipe 44 through the emergency drain pipe joint 41. The main body of the emergency drain pipe 44 passes through the wall 1 to the outside and slopes outward by 2%. With the help of gravity, the water flows smoothly to the outside in the pipe to achieve drainage. The exterior wall decorative cover ring 45 seals the connection between the wall 1 and the pipe to prevent water leakage and ensure aesthetics. When the water in the cabinet 2 is drained, the movable protective cover plate 47 loses the force of the water and slides down along the guide rod 46 under its own weight to cover the lower end of the emergency drain pipe joint 41 again and restore the sealed state.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
