Description

Technical Field

[0001] The utility model relates to the technical field of water heaters, and more specifically, to a flue supporting device for a water heater. Background Art

[0002] The flue of a water heater refers to an important channel for the water heater to discharge combustion exhaust gas. It is responsible for safely discharging the exhaust gas generated by combustion to the outside, preventing the exhaust gas from accumulating indoors and causing secondary pollution.

[0003] When there is strong wind outside, the airflow directly acts on the flue, causing the wind pressure inside the flue to increase, exceeding the tolerance range of the strong exhaust device. The water heater will generally automatically shut down and enter a protection state, and cannot be used normally.

[0004] After searching, the Chinese patent with application number CN202020037301.2 discloses a gas water heater flue that can prevent backdraft from blowing out. In actual operation, after the flue is connected to the exhaust port of the water heater, it can effectively reduce the wind pressure in the flue, prevent backdraft from blowing out, and has the advantages of small size, simple structure, low cost, long life, and easy disassembly and assembly.

[0005] When the above-mentioned gas water heater flue that prevents backdraft from blowing out is actually used, the water heater will generate a large amount of exhaust gas. The large amount of exhaust gas circulating inside the flue will cause the flue to shake. Long-term operation will cause the flue to deform, making the internal space of the flue smaller, hindering the smooth discharge of exhaust gas, thereby reducing the exhaust efficiency. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a water heater flue supporting device to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A flue support device for a water heater comprises a flue connected to the upper surface of the water heater, a support box is provided on the outside of the flue, and a support assembly is installed inside the support box; the support assembly comprises a threaded rod, a push plate and a pressing plate are installed on the outside of the threaded rod, and two movable rods are provided between the push plate and the pressing plate, and support frames are installed on the outsides of the two movable rods, and the tops of the two support frames are fixedly connected to movable seats, and the insides of the two movable seats are movably connected to a first support ring; two fixed rods are fixedly connected to the inside of the support box, and the tops of the two fixed rods are fixedly connected to a second support ring, and the insides of the two second support rings and the first support ring are fixedly connected to protective pads, the push plate and the pressing plate are both threadedly connected to the threaded rod, and the two movable rods are movably connected inside the support frame.

[0009] By adopting the above technical solution: the threaded rod is connected to the internal thread of the support box, so that the rotation of the threaded rod can drive the push plate and the pressing plate to rotate, and the inclined surface on one side of the push plate and the pressing plate can drive the bottom end of the movable rod to move, and the two support frames provide supporting force for the movement of the movable rod, so that the top ends of the two movable rods drive the movable seat to move, and the two first support rings are movably connected inside the movable seat on one side, so that the two first support rings can move relative to each other and be fixed on both sides of the flue, and the two second support rings are used to support the bottom end of the flue and cooperate with the two first support rings, so that the flue can be effectively supported.

[0010] As a further description of the above technical solution: two mounting brackets are fixedly connected to one side of the support box.

[0011] By adopting the above technical solution: the support box is easily fixed to the wall through two mounting brackets, so that the two second support rings inside the support box can better support under the flue.

[0012] As a further description of the above technical solution: an air collecting hood is fixedly connected to the inside of the flue, and one side of the air collecting hood is connected to an exhaust hood.

[0013] By adopting the above technical solution: the gas collecting hood is convenient for gathering the exhaust gas so that the exhaust gas can be discharged in a centralized manner, and the exhaust hood is convenient for diffusing the exhaust gas. At the same time, the gas collecting hood and the exhaust hood can prevent the outdoor cold air from flowing back into the room through the flue to a certain extent, and can also reduce the noise during the exhaust of the flue.

[0014] As a further description of the above technical solution: two connecting blocks are fixedly connected to the outside of the flue, and protective shells are provided on the outside of the two connecting blocks. A protective net is fixedly connected to the inside of the protective shell, and two sliding grooves are provided on the inside of the protective shell. Two connecting bolts are installed inside the protective shell.

[0015] By adopting the above technical solution: two connecting blocks can be inserted into the protective shell and the protective shell is fixed to the flue through two connecting bolts, which facilitates the quick disassembly and installation of the protective shell, thereby facilitating the cleaning of the surface of the protective net.

[0016] Technical effects and advantages of this utility model:

[0017] 1. By providing a support assembly, compared with the prior art, the pressing plate presses one end of the movable rod downward through the inclined surface of the lower surface. With the support of the two support frames, the other ends of the two movable rods drive the two first support rings to be clamped and fixed to the outside of the flue. This can effectively provide additional support for the flue, preventing the flue from shaking or deflecting due to the flow of large amounts of exhaust gas or other external forces, thereby enhancing the overall stability of the water heater, reducing the deformation of the flue, and extending the service life of the flue;

[0018] 2. By setting connecting blocks, protective shells, protective nets, slides and connecting bolts, compared with the existing technology, two connecting blocks are inserted into the slides inside the protective shell, and then the protective shell is fixed to the flue with two connecting bolts, so that the protective net can protect one end of the flue, which is beneficial to prevent birds and small animals from entering the flue. At the same time, it is convenient to quickly disassemble and install the protective shell, thereby facilitating the cleaning of the protective net. BRIEF DESCRIPTION OF THE DRAWINGS
