Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of kitchen appliances, and in particular relates to a kitchen fume exhaust port. Background Art
[0002] Compared with residential buildings, commercial buildings produce more kitchen fume exhaust gas, so it is crucial to set up a reasonable fume exhaust system. The fume exhaust system includes fume hoods, fume exhaust pipes, fume purification devices, fume fans, etc. Among them, the technologies of fume purification devices, fume fans and fume hoods are relatively mature. Through reasonable sample selection, the original design intention can be better achieved, but there are no specific specifications to guide the design of fume exhaust ports. In existing projects, the fume exhaust port is generally set on the air outlet section of the fume fan, and the fume is discharged upward in the form of a conical hood or the fan is connected to an external air duct to discharge the fume obliquely downward. The manufacturing process of the conical hood is complicated, and the fume exhaust resistance is large. The oblique downward discharge of fume will cause the kitchen fume smell to spread downward, affecting the daily life of the residents below. In the long run, it will also cause pollution to the surrounding environment near the fume exhaust port.
[0003] At present, commercial kitchen oil fume exhaust vents are mostly provided in the following two ways: a conical hood is set above the fan, and the air duct of the fan outlet section is turned down at a certain angle and a protective net is directly added to serve as the oil fume exhaust vent.
[0004] The density of kitchen fume is greater than that of air. The exhaust outlet with a protective net directly added to the duct at a certain angle will cause the fume to sink, polluting the environment around the exhaust outlet, and the smell of the fume will have varying degrees of impact on the people living below. The exhaust outlet with a hood directly added above the fan has the disadvantages of large exhaust resistance and complex hood manufacturing.
[0005] In view of the above problems, it is necessary to improve them. Utility Model Content

[0009] As a preferred solution of the utility model, the elbow is in a U-shaped structure, and the end of the elbow is arranged obliquely to the drain pipe, and the inclination angle is 35° to 50°.
[0010] As a preferred solution of the utility model, the highest point of the connection between the elbow and the drain pipe is lower than the top of the short drain pipe.
[0011] As a preferred solution of the utility model, a sewage outlet is provided at the bottom of the curved pipe, and a sewage outlet cover is screwed onto the sewage outlet.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0031] Example:
[0032] like Figure 1-2 As shown, Figure 1 This is a cross-sectional view of a kitchen fume exhaust port of the utility model; Figure 2 For this utility model Figure 1 A-axis partial enlarged view.
[0033] A kitchen fume exhaust port comprises an air outlet pipe 1 and an air inlet pipe 4 for connecting to an exhaust pipe of a fan, wherein the air outlet pipe 1 is arranged in a vertical direction and communicated with the air inlet pipe 4; a drainage device 10 for discharging rainwater is arranged at the bottom of the air outlet pipe 1; the technology improves the traditional fume exhaust port so that the fume can be discharged upwardly to the sky, thereby alleviating the influence of the fume smell sinking on the lower building, and better improving the current poor environment near the fume exhaust port, thereby making the fume exhaust system more environmentally friendly. At the same time, compared with the hood fume exhaust form, the system resistance is smaller and the manufacturing process is simpler.
[0034] The utility model has a simple structure. The air outlet duct is arranged in the vertical direction. The air outlet of the air outlet duct is located at the top of the kitchen fume exhaust port. The fume can be discharged directly from the high altitude, reducing the impact of the downward discharge of fume on the odor of the lower building. In addition, the drainage transition pipe 11 is a downward extension of the air outlet duct 1. The drainage transition pipe 11 is located at the lower end of the air inlet pipe 4, and the connection between the drainage transition pipe 11 and the air inlet pipe 4 is an arc transition structure.
[0035] The utility model is cleverly designed and directly discharges oil smoke from a high altitude, which can significantly improve the phenomenon of poor environment near the oil smoke outlet caused by the accumulation of time for downward oil smoke discharge, and improve the utilization efficiency of the environment around the oil smoke outlet.
[0036] The air outlet pipe 1 and the air inlet pipe 4 are arranged obliquely, and the inclination angle is 85°~89°. In this embodiment, the inclination angle of the air outlet pipe 1 and the air inlet pipe 4 is 85°. The above scheme is adopted, so that the air inlet pipe 4 is arranged obliquely and connected with the drainage transition pipe 11, further preventing rainwater from entering the fan exhaust pipe and affecting the fan.
[0037] A protective cover 2 is provided on the top of the air outlet pipe 1, and a plurality of protective holes 3 connected with the air outlet pipe 1 are formed on the protective cover 2; the plurality of protective holes 3 are circumferentially equidistantly arranged on the protective cover 2; the protective holes 3 serve to prevent birds, insects and animals from entering the oil fume exhaust system; compared with the hood oil fume exhaust method, the utility model has a simpler manufacturing process and a smaller discharge resistance of the entire system.
[0038] Specifically, Figure 2As shown, the drainage device 10 includes a drainage transition pipe 11, the bottom of the drainage transition pipe 11 is connected to a drainage short pipe 12, the bottom of the drainage short pipe 12 is connected to a bend pipe 13, and the bend pipe 13 is connected to a drainage pipe 14; by setting the drainage device 10, the utility model can drain water to a nearby drainage point through the drainage transition pipe 11, the drainage short pipe 12, the bend pipe 13 and the drainage pipe 14.
[0039] The inner diameter of the drainage transition pipe 11 is larger than the inner diameter of the drainage short pipe 12. The inner diameters of the drainage short pipe 12, the elbow 13 and the drainage pipe 14 are the same. This arrangement allows the water pressure of the elbow 13 to resist the dynamic pressure at the exhaust port and prevent oil smoke from being discharged from the drainage short pipe.
[0040] Specifically, the elbow 13 has a U-shaped structure, and the end of the elbow 13 is arranged obliquely with the drain pipe 14, and the inclination angle is 35°~50°. In this embodiment, the inclination angle between the end of the elbow 13 and the drain pipe 14 is 41°. The U-shaped structure of the elbow can store water and can effectively prevent oil smoke from being discharged from the short drainage pipe; by arranging the end of the elbow and the drain pipe obliquely, the drainage outlet of the drain pipe is opened downward, so that excess rainwater in the drainage device can be quickly discharged, and at the same time, the possibility of the drainage device being blocked is greatly reduced.
[0041] The highest point of the connection between the elbow 13 and the drainage pipe 14 is lower than the top of the drainage short pipe 12; this can prevent excessive rainwater from being stored in the elbow and also prevent rainwater from flowing back into the drainage transition pipe through the drainage short pipe.
[0042] A drain port 15 is provided at the bottom of the curved pipe 13, and a drain cover 16 is screwed onto the drain port 15; rainwater sediment accumulates in the curved pipe 13, thereby blocking the curved pipe 13. The drain cover 16 is provided on the drain port 15 to facilitate the cleaning of the sediment.
[0043] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
