Description

Technical Field

[0001] The invention relates to the technical field of kitchenware, and in particular to a detachable oil absorption and sewage discharge device. Background Art

[0002] The water curtain range hood is a new type of kitchen range hood. It uses a fan or other device to guide the oil smoke through the internal water curtain. It uses the principle that high-temperature oil condenses when it meets low-temperature objects to separate the oil in the oil smoke through the low-temperature water curtain, and then discharges the oil through the water flow. Compared with traditional range hoods, water curtain range hoods have stronger filtering performance for oil smoke.

[0003] A Chinese patent discloses a self-cleaning environmentally friendly range hood [application number: CN201120268469.5, publication number: CN202253853U], including: a housing and its air inlet and outlet, and a suction fan provided with a water curtain type oil fume filter. Although the water curtain type oil fume filter can effectively separate oil fume, high-temperature grease solidifies when it is cold, and is easily adhered to the low-temperature inner wall of the device in places with low water flow rates. Since the device itself is inconvenient to disassemble and its interior is difficult to clean, grease accumulation over time affects the oil filtering effect. Therefore, it is very necessary to design a detachable oil suction and sewage discharge device that is easier to clean. Summary of the invention

[0004] In view of the technical problems of the prior art, the present invention provides a detachable oil suction and sewage discharge device.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A detachable oil suction and sewage discharge device, characterized in that it comprises: an outer tank, a base, and a water supply system; a cavity is arranged in the outer tank, and an overflow trough is arranged at the top of the outer tank; a drainage plate is fixedly connected to the bottom of the overflow trough to drain the water in the overflow trough into the cavity of the outer tank; the water supply system comprises a water supply pipeline, and the water outlet end of the water supply pipeline is communicated with the overflow trough; a connecting plate is arranged between the bottom end of the outer tank and the base, and the connecting plate is embedded in the base so that the outer tank can be detachably connected to the base; a fan is fixedly connected to the top of the overflow trough.

[0007] During actual operation, water is injected into the overflow trough through a water pipe. There is a gap between the bottom of the overflow trough and the side wall of the outer tank. A drainage plate is provided below the gap, so that the water in the overflow trough can overflow from the bottom of the overflow trough. The overflowed water is drained into the cavity in the outer tank through the drainage plate, thereby forming a water curtain. At the same time, the fan at the top of the overflow trough continuously sucks the oil smoke into the cavity in the outer tank, so that the sucked high-temperature oil smoke contacts the low-temperature water curtain, and then the grease in the high-temperature oil smoke condenses into blocks when it is cold. The condensed grease blocks are flushed out of the outer tank by the water curtain, thereby effectively filtering the oil smoke. A connecting plate is provided between the other end of the outer tank and the base. The outer tank can be separated from the base through the connecting plate, so that the inner wall of the outer tank and the top of the base are exposed, which is convenient for the staff to clean.

[0008] Furthermore, the connecting plate is L-shaped, and the wider end of the connecting plate is embedded in the base.

[0009] Furthermore, the base is provided with a groove corresponding to the connecting plate, and the height of the connecting plate is greater than the depth of the groove.

[0010] Furthermore, an inner liner is disposed in the cavity of the outer liner, and the inner liner includes an inner liner body and an air gathering plate, and the inner liner body and the air gathering plate are detachably connected via a connecting structure.

[0011] Furthermore, the connection structure includes a plug-in plate, which is fixedly connected to one end of the inner tank body close to the wind gathering plate, and the wind gathering plate is provided with a plug-in slot corresponding to the plug-in plate.

[0015] Furthermore, the base is also fixedly connected with a sewage pipe, and the sewage pipe is communicated with the sewage tank.

[0016] Furthermore, the water delivery system also includes a water tank, the water inlet end of the water delivery pipeline is arranged at the bottom of the water tank, and the water tank surrounds the base.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] The connection structure makes it easy for the components to be disassembled, making it convenient for the staff to clean.

[0019] Multiple layers of wind-collecting plates are arranged inside, which makes the oil smoke stay longer inside the device and effectively enhances the filtering effect.

[0020] Equipped with a water tank, used water can be recycled.

[0021] The device itself is cylindrical, and multiple cooking workstations can be set up around it, making it more suitable for restaurant kitchens and other work environments where a large number of dishes need to be cooked at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0029] A detachable oil suction and sewage discharge device comprises: an outer liner 1, a base 3, and a water supply system. The outer liner 1 is a barrel-shaped shell provided with a cavity, an overflow trough 11 is provided at the top of the inner cavity of the outer liner 1, and an upper air inlet 12 is provided on the side wall of the outer liner 1. There is a gap between the bottom of the overflow trough 11 and the side wall of the outer liner 1, and a drainage plate 111 is provided below the gap, and the water in the overflow trough can flow out from the gap at the bottom of the overflow trough to the drainage plate. The water supply system comprises a water supply pipe 41, and the water outlet end of the water supply pipe 41 is connected to the overflow trough 11. For example: in this embodiment, the water outlet end of the water supply pipe 41 is located above the overflow trough, and the water flowing out through the water supply pipe 41 can fall into the overflow trough. A connecting plate 14 is provided between the bottom end of the outer liner 1 and the base 3, and the connecting plate 14 is embedded in the base 3 so that the outer liner 1 can be detachably connected to the base 3. The top of the overflow tank 11 is fixedly connected with a fan 112. In this embodiment, the fan 112 is arranged at the top of the axis of the cavity inside the outer liner 1, and is used to suck the external air into the internal cavity of the outer liner 1 through the upper air inlet 12 or the bottom inlet of the side wall of the outer liner 1, and attract the gas in the internal cavity from bottom to top to be discharged from the air outlet of the fan. Preferably, the fan adopts a vortex impeller to increase the smoking efficiency while saving energy.

[0030] The outer tank is a conical barrel-shaped shell with a small top and a large bottom. The diameter of the top cross-sectional circle of the outer tank is smaller than the diameter of the bottom cross-sectional circle. Therefore, the inner wall of the outer tank is an inclined slope. The water flowing out of the bottom of the overflow tank at the top of the internal cavity flows to the drainage plate below the overflow tank to be drained. The drainage plate is inclined downward from the center of the internal cavity outward, and a drainage protrusion is fixedly connected to the bottom of the drainage plate in a vertical direction. The cooling water is transported to the overflow tank through the water delivery pipeline of the water delivery system, so as to fill the overflow tank with water. The water injected into the overflow tank flows out from the bottom gap of the overflow tank and falls down under the action of gravity. Part of the water flows downward closely against the inner wall of the outer tank to generate a first water curtain, and the other part of the water flows along the drainage plate to the cavity of the outer tank, and finally flows to the drainage protrusion. Through the drainage protrusion, the cooling water flows downward in a vertical direction to generate a second water curtain. Through the cooperation of the drainage plate and the inner wall of the outer tank, a double water curtain is effectively generated in the cavity of the outer tank. At the same time, the fan installed on the top of the overflow tank continuously sucks the external oil smoke from the bottom of the outer tank and the upper air inlet and discharges the sucked oil smoke from the air outlet on the fan. The movement direction of the oil smoke is opposite to the movement direction of the water curtain, thus forming a countercurrent. Under the guidance of the fan, part of the oil smoke passes through the water curtain generated by the guide plate, and the other part of the oil smoke contacts the water curtain on the inner wall of the outer tank, so that the grease condenses into blocks when it is cold, and the water curtain flushes the condensed grease out of the outer tank, thereby effectively filtering the oil smoke. The bottom of the outer tank is evenly provided with multiple connecting plates, through which the outer tank can be separated from the base, so that the inner wall of the outer tank and the top of the base are exposed, which is convenient for staff to clean.

[0031] The connecting plate 14 is L-shaped and is an arc-shaped shell. The connecting plate 14 is evenly arranged at the bottom end of the outer container 1. For example, in this embodiment, the connecting plate 14 divides the bottom end of the outer container 1 into four equal parts. The connecting plate 14 is embedded in a groove 31 on the base 3 corresponding to the connecting plate 14. The arc length of the groove 31 is equal to the arc length of the wider end of the connecting plate 14. At the same time, the depth of the groove 31 is equal to the height of the wider end of the connecting plate 14, so that the height of the connecting plate 14 is greater than the depth of the groove 31.

[0032] The thickness of the connecting plate is equal to that of the outer tank. The connecting plate is an arc-shaped shell. The cross section of the bottom end of the connecting plate is a concentric circle with the same diameter as the cross section of the bottom end of the outer tank, so that the curvature of the connecting plate is the same as that of the outer tank, so that when the water flows to the connecting plate, the water flow will not be blocked by the connecting plate, so that the water flow is smoother. The height of the connecting plate is greater than the depth of the groove on the base, so that there is a gap between the bottom end of the outer tank and the base, which is convenient for the fan to inhale oil smoke from the bottom end of the outer tank. The connecting plate is L-shaped, with the narrower end fixedly connected to the bottom end of the outer tank and the wider end embedded in the groove on the base. On the one hand, the connecting plate itself is not easy to affect the flow of oil smoke, and on the other hand, the contact area between the connecting plate and the groove is increased, making the connection between the outer tank and the base more stable.

[0033] The cavity of the outer liner 1 is also provided with an inner liner 2, and the inner liner 2 includes an inner liner body 21 and a wind collecting plate 22. A plurality of plug-in boards 231 are evenly provided at the bottom end of the inner liner body 21. For example, in this embodiment, the plug-in board 231 divides the bottom end of the inner liner body 21 into four equal parts. The plug-in board 231 is an arc-shaped shell. The top end of the wind collecting plate is provided with a plug-in slot 232 corresponding to the plug-in board 231. The arc length of the plug-in slot 232 is equal to the arc length of the plug-in board 231, and the depth of the plug-in slot 232 is less than the height of the plug-in board 231. The inner liner body 21 and the wind collecting plate 22 are detachably connected by embedding the plug-in board 231 in the plug-in slot 232.

[0034] The main body of the liner is a barrel-shaped shell that is connected to the top and bottom ends. The thickness of the plug-in board is equal to the thickness of the main body of the liner, the curvature of the plug-in board is the same as that of the main body of the liner, and the height of the plug-in board is greater than the depth of the plug-in slot, so that there is a gap between the main body of the liner and the wind gathering plate. The top of the main body of the liner is a cone, so that the top of the main body of the liner is convex upward, and the cone is located below the guide plate, so that the water curtain generated by the guide plate can fall onto the cone, and the lower end of the cone is bent downward in the vertical direction, so that the water flowing onto the cone falls in the vertical direction, thereby generating a third water curtain. The lower end of the cone extends outward from the center of the main body of the liner, so that the generated third water curtain surrounds the wind gathering plate. At the same time, the axis lines of the outer liner, the inner liner body, and the wind gathering plate coincide with each other. Under the action of the wind force of the fan, part of the cooling water of the triple water curtain passes through the gap between the inner liner body and the wind gathering plate and moves upward in the vertical direction, and finally gathers in the cavity of the inner liner body, so that the cavity of the inner liner body is filled with low-temperature water droplets, and the inner liner body is in a low-temperature state. The wind force of the fan sucks the external oil smoke into the outer liner through the upper air inlet on the outer liner body and the bottom of the outer liner. Part of the oil smoke enters the gap between the outer liner and the inner liner, and moves upward in the vertical direction, so that the grease contacts the triple water curtain to form grease blocks. Another part of the oil smoke passes through the gap between the inner liner body and the wind gathering plate and enters the cavity of the inner liner body. It moves upward in the cavity of the inner liner body in the vertical direction and contacts the low-temperature water droplets in the cavity to form mixed oil droplets containing water. The mixed oil droplets gradually fall to the wind gathering plate under the action of gravity. The wind gathering plate is provided with a funnel-shaped groove, and a through hole is provided at the lower end of the groove. On the one hand, the wind force influence of the fan is reduced, thereby slowing down the movement speed of the oil smoke and prolonging the residence time of the oil smoke in the inner tank cavity, so that the oil smoke is fully in contact with the low-temperature water droplets. On the other hand, the funnel-shaped groove gathers the falling mixed oil droplets, which is convenient for the discharge of the mixed oil droplets.

[0035] At the same time, a plurality of plug-in plates are evenly arranged at the bottom of the wind gathering plate, so that the plurality of wind gathering plates can be plugged together from top to bottom. Since the wind gathering plate has a retention effect on oil smoke, the retention effect of oil smoke is enhanced as the number of wind gathering plates increases, thereby extending the retention time of oil smoke, and then effectively enhancing the filtering effect.

[0036] When performing actual cleaning operations, first separate the outer tank from the base to expose the inner tank and the wind gathering plate. At this time, separate the inner tank body from the wind gathering plate through the plug-in plate and the plug-in slot, and then separate the wind gathering plates one by one from top to bottom, so that the inner wall of the inner tank body and the wind gathering plate are exposed, so that it is convenient for the staff to clean the grease blocks and mixed oil droplets attached to the inner wall of the outer tank, the inner wall of the inner tank body and the wind gathering plate that have not been discharged in time.

[0037] A drainage trough 32 is also provided on the base 3. The drainage trough 32 is located below the wind gathering plate. The outer wall of the drainage trough 32 is an inclined surface inclined upward from the axis of the outer bladder. The base 3 is also fixedly connected with a drainage pipe 33, which is connected to the drainage trough 32.

[0038] The water supply system also includes a water tank 42, which surrounds the base 3. A gap is left between the water tank 42 and the base 3. The water tank 42 is also provided with a through opening corresponding to the sewage pipe 33. The water inlet end of the water supply pipe 41 is set at the bottom of the water tank 42.

[0039] The drain trough is located below the wind gathering plate, and the axis of the drain trough coincides with the axis of the wind gathering plate. The drain pipe extends outward through the opening on the water tank. The device divides the grease in the inhaled oil smoke into two parts and discharges them outside the device. One part of the grease contacts the low-temperature water droplets in the cavity of the inner tank body to form mixed oil droplets. The mixed oil droplets gather at the funnel-shaped groove on the wind gathering plate, and finally drip into the drain trough and are discharged through the drain pipe connected to the drain trough. The other part of the grease contacts the triple water curtain to generate grease blocks, which eventually flow to the base with the water curtain. Under the action of the wind force of the fan, the grease blocks gradually move toward the drain trough along the inclined surface of the outer wall of the drain trough with the water of the water curtain. During the movement, due to the different specific gravities of oil and water, the grease blocks gradually separate from the water, and finally the grease blocks flow into the drain trough and are discharged through the drain pipe. The separated water moves along the slope of the drainage trough under the action of gravity, and finally flows into the water tank surrounding the base through the gap between the base and the water tank, thereby effectively reducing the waste of water resources. The water in the water tank is continuously pumped into the water pipeline through a micro water pump connected to the water inlet end of the water pipeline, and finally injected into the overflow tank from the water outlet end of the water pipeline.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
