Description

Technical Field

[0001] The utility model relates to the technical field of gas water heater manufacturing, in particular to a simplified structure of an exhaust collecting tube of a gas water heater. Background Art

[0002] The gas water heater exhaust manifold is an exhaust device used in various gas water heaters. Its function is to discharge exhaust gas to the outside when the gas water heater is burning while preventing outside air from entering.

[0003] However, the prior art has too many structural components, usually including an exhaust pipe, a headwind baffle, a limit plate, and an axle rod structure. In addition, the four components have complex structures, complex processing techniques, and long working hours.

[0004] Therefore, how to simplify the structure of the exhaust manifold of the gas water heater and improve the production and installation efficiency has become a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

[0005] In view of the above-mentioned defects of the prior art, the utility model provides a simplified structure of the exhaust manifold of the gas water heater, the purpose of which is to simplify the structure of the exhaust manifold of the gas water heater and improve the production and installation efficiency.

[0006] To achieve the above-mentioned purpose, the utility model discloses a simplified structure of an exhaust manifold of a gas water heater, comprising a cylindrical body of the exhaust manifold and a baffle disposed in the body and connected to the body in a swivel pair.

[0007] The baffle is an integrated headwind baffle, comprising a headwind baffle body that is curved in an arc shape, and two rotating convex points that are connected to the inner wall of the cylinder to form a revolving pair;

[0008] The side of the upwind baffle body facing the outside of the corresponding gas water heater is inwardly concave;

[0009] The two rotating convex points are circular protrusions that are integral with the headwind baffle body, and are clamped on the inner wall of the cylinder so that the baffle and the cylinder form a rotating pair in which the rotating axis is located on one side of the axis of the cylinder and is in a spatially perpendicular relationship with the axis of the cylinder;

[0010] When the headwind baffle body rotates to a state of closing the cylinder, the projection of the plate body on the side with a smaller rotating shaft area on the cross section of the cylinder is an arc shape that matches the corresponding position of the inner cavity of the cylinder, and there is a gap between the end of the plate body on the other side with a larger rotating shaft area and the inner wall of the cylinder.

[0011] Preferably, in the cylinder, when the headwind baffle body rotates to a state of closing the cylinder, a limiting protrusion is provided on the outer side of the plate body located on the side with a smaller area of ​​the rotating shaft.

[0012] Preferably, when the headwind baffle body rotates to a state of closing the cylinder, a gap between the end of the plate body on the other side of the rotating shaft with a larger area and the inner wall of the cylinder is 3 mm to 5 mm.

[0013] Preferably, the headwind baffle body is in the shape of an arc with a curvature radius of 25 to 30 mm corresponding to a central angle of 80 on a cross section of the rotating shaft including the axis of the cylinder.

[0014] Preferably, the minimum distance between the rotating shaft and the axis of the cylinder is 8 mm.

[0015] Beneficial effects of the utility model:

[0016] The utility model only includes two components, namely, an exhaust pipe and a headwind baffle. Not only can the pipe body be sealed more quickly when external air enters, but also there are fewer parts, which can reduce consumables and simplify processing technology and installation steps.

[0022] Example

[0023] like Figures 1 to 4 As shown, the simplified structure of the exhaust manifold of the gas water heater includes a cylindrical body 1 of the exhaust manifold, and a baffle 2 which is arranged in the body 1 and connected to the body 1 in a rotary pair.

[0024] The baffle 2 is an integrated headwind baffle, including a headwind baffle body 21 that is curved in an arc shape, and two rotating protrusions 22 that form a rotary joint connection with the inner wall of the cylinder 1;

[0025] The side of the upwind baffle body 21 facing the outside of the corresponding gas water heater is inwardly concave;

[0026] The two rotating convex points 22 are circular protrusions that are integral with the headwind baffle body 21, and are clamped on the inner wall of the cylinder 1 so that the baffle 2 and the cylinder 1 form a rotating pair in which the rotating axis is located on one side of the axis of the cylinder 1 and is in a spatially perpendicular relationship with the axis of the cylinder 1;

[0027] When the headwind baffle body 21 rotates to a closed cylinder 1 state, the projection of the plate body on the side with a smaller rotating shaft area on the cross section of the cylinder 1 is an arc shape that matches the corresponding position of the inner cavity of the cylinder 1, and there is a gap between the end of the plate body on the other side with a larger rotating shaft area and the inner wall of the cylinder 1.

[0028] The utility model transforms the shaft of the existing exhaust manifold into two rotating protrusions 22, and transforms the flat-plate baffle 2 into a curved upwind baffle body 21, thereby increasing the area of ​​the upwind baffle body 21. Not only can the cylinder body 1 be sealed more quickly when external air enters, but there are also fewer parts, which can reduce consumables and simplify processing technology and installation steps.

[0029] In some embodiments, in the cylinder 1, when the headwind baffle body 21 rotates to a state of closing the cylinder 1, a limiting protrusion 3 is provided on the outer side of the plate body located on the side with a smaller rotating shaft area.

[0030] In some embodiments, when the headwind baffle body 21 rotates to a state of closing the cylinder 1, the gap between the end of the plate body on the other side of the rotating shaft with a larger area and the inner wall of the cylinder 1 is 3 mm to 5 mm.

[0031] In some embodiments, the headwind baffle body 21 is in the shape of an arc with a radius of curvature of 25 to 30 mm corresponding to a central angle of 80 on a cross section of the rotating shaft including the axis of the cylinder 1 .

[0032] Preferably, the minimum distance between the rotary shaft and the axis of the cylinder 1 is 8 mm.

[0033] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
