Description

Technical Field

[0001] The utility model relates to a staggered exhaust device adjacent to a toilet. Background Art

[0002] At present, two adjacent toilets in each building are equipped with a common exhaust duct, which is located between the two adjacent toilets and has an air inlet at the top of the toilets on each floor. The top of the exhaust duct extends to the roof to discharge the dirty air in each toilet into the atmosphere. This traditional adjacent toilet exhaust duct has a serious phenomenon of "gas and smell" between the dirty air in the adjacent toilets, as the air inlets in the two toilets on each floor are on the same horizontal plane, resulting in poor exhaust effect. Summary of the invention

[0003] The utility model aims to provide a staggered exhaust device adjacent to a toilet to solve the above-mentioned problem.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A staggered exhaust device for adjacent toilets comprises an exhaust duct, wherein an elbow outlet pipe is provided at the air inlet of the exhaust duct, the outlet of the elbow outlet pipe is located in the exhaust duct and extends vertically upward for a distance, the outlets of two elbow outlet pipes of two adjacent toilets on the same floor are located on two high and low planes, the outlets of two elbow outlet pipes of toilets on upper and lower adjacent floors are arranged alternately high and low, and the air inlet of the elbow outlet pipe is located outside the air inlet of the exhaust duct and is connected to the air inlet duct through a fire check valve.

[0006] As a further description of the above technical solution: the air inlet duct extends horizontally to a distance inside the bathroom, and the length of the air inlet duct is 20 cm to 40 cm.

[0007] As a further description of the above technical solution: the air inlet duct is a through pipe, and a plurality of air equalizing holes are arranged on the pipe wall near the air inlet duct opening.

[0008] As a further description of the above technical solution: the air outlets of the two elbow air outlet pipes of the two adjacent toilets on the same floor are located on two high and low planes, and the difference between the two planes is 10cm to 40cm.

[0009] As a further description of the above technical solution: the axis line of the elbow outlet pipe located in the exhaust pipe and extending vertically upward for a distance is arranged parallel to the axis line of the exhaust pipe.

[0010] As a further description of the above technical solution: a rain cap is provided at the rooftop external outlet end of the exhaust duct.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The utility model overcomes the disadvantages of the traditional adjacent toilet exhaust ducts that the air inlets in the two toilets on each floor are on the same horizontal plane, which leads to the serious phenomenon of "gas and smell" of the dirty air in the adjacent toilets, and the poor exhaust effect. Since the air outlets of the two elbow air outlet pipes in the two adjacent toilets on the same floor are located on the planes of the upper and lower floors, the air outlets of the two elbow air outlet pipes in the toilets on the upper and lower floors are arranged alternately in high and low positions, and the air inlet of the elbow air outlet pipe is located outside the air inlet of the exhaust duct and is connected to the air inlet duct through a fire check valve, the utility model prevents the dirty air in the adjacent toilets from "gas and smell" and the air inlet duct of the utility model is also more conducive to the rapid discharge of the dirty air in the bathroom into the exhaust duct, which can improve the sewage discharge effect of the exhaust duct and achieve the effect of preventing backflow.

[0013] 2. The utility model has a simple structure, still utilizes the traditional exhaust pipe, the material is easily available, the cost is low, and the use effect is good. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] Reference Figures 1-2A staggered exhaust device for adjacent toilets includes an exhaust duct, including an exhaust duct 1, an elbow air outlet pipe 4 is provided at the air inlet of the exhaust duct 1, the outer wall of the elbow air outlet pipe 4 passing through the air inlet and the inner wall of the corresponding air inlet are sealed with cement mortar, the air outlet of the elbow air outlet pipe 4 is located in the exhaust duct and extends vertically upward for a distance, the air outlets of the two elbow air outlet pipes of the two adjacent toilets on the same floor are located on two high and low planes, and the difference between the two planes is 10cm to 40cm. The air outlets of the two elbow air outlet pipes of the toilets on the upper and lower adjacent floors are arranged alternately in height, that is, the length of the elbow air outlet pipe in the exhaust duct of the toilet on the first floor is greater than the length of the elbow air outlet pipe in the exhaust duct of the toilet on the second floor, the length of the elbow air outlet pipe in the exhaust duct of the toilet on the third floor is greater than the length of the elbow air outlet pipe in the exhaust duct of the toilet on the second floor, or the length of the elbow air outlet pipe in the exhaust duct of the toilet on the first floor is less than the length of the elbow air outlet pipe in the exhaust duct of the toilet on the second floor, the length of the elbow air outlet pipe in the exhaust duct of the toilet on the third floor is less than the length of the elbow air outlet pipe in the exhaust duct of the toilet on the second floor, and so on. The axis of the elbow air outlet pipe located in the exhaust duct and extending vertically upward for a distance is arranged parallel to the axis of the exhaust duct.

[0018] The air inlet of the elbow outlet pipe 4 is located outside the air inlet of the exhaust duct 1 and communicates with the air inlet duct 2 through the fire check valve 3. The air inlet duct is a through pipe with a diameter of 10 cm. The air inlet duct extends horizontally to a distance in the bathroom. The length of the air inlet duct is 20 cm to 40 cm. A plurality of air equalization holes 6 are provided on the pipe wall near the air inlet duct opening, so as to facilitate the inhalation of the dirty air in the bathroom into the air inlet duct.

[0019] The fire-proof check valve 3 is an existing product, so it is not described again.

[0020] The air outlets of the two elbow air outlet pipes of two adjacent toilets on the same floor are located on two high and low planes, and the difference between the two planes is 10cm to 40cm, which can effectively prevent the mutual "gas leakage" and "odor leakage" between the two adjacent toilets.

[0021] The axis center line of the elbow outlet pipe which is located in the exhaust pipe and vertically extends upward for a certain distance is arranged parallel to the axis center line of the exhaust pipe.

[0022] A rain cap 7 is provided at the rooftop outer outlet end 5 of the exhaust duct to prevent rainwater from entering the exhaust duct.

[0023] When the utility model is used, the exhaust duct 1 generates suction to suck the dirty air in each of the two adjacent toilets into the exhaust duct along the elbow outlet pipe, the fire check valve, and the air inlet duct, and then discharges the dirty air in each toilet into the atmosphere along the exhaust duct opening 5 outside the roof. Since the air outlets of the two elbow outlet pipes of the two adjacent toilets on the same floor of the utility model are located on the planes of the upper and lower floors, the air outlets of the two elbow outlet pipes of the toilets on the upper and lower adjacent floors are arranged alternately in height, and the air inlet of the elbow outlet pipe is located outside the air inlet of the exhaust duct and communicates with the air inlet duct through the fire check valve, the dirty air in the adjacent toilets of the utility model will not produce the phenomenon of "gas cross-talk" and "odor cross-talk", and the air inlet duct of the utility model is also more conducive to the rapid discharge of the dirty air in the toilet into the exhaust duct, which can improve the sewage discharge effect of the exhaust duct and achieve the effect of preventing backflow.
