Description
Technical Field
[0001] This utility model relates to the field of heating furnace technology, specifically to a structure for collecting condensate and backflow water from a heating furnace. Background Technology
[0002] A heating boiler is a device that converts fuel combustion or electrical energy into heat energy for heating purposes.
[0003] Heating boilers come in various types according to different classification standards, including gas-fired boilers, coal-fired boilers, and electric boilers. They can also be categorized into freestanding, floor-standing, tabletop, horizontal, and wall-mounted types to suit different installation environments and space requirements.
[0004] The working principle of a heating boiler is mainly to transfer the heat energy generated by fuel combustion or the heat energy converted from electrical energy to water or other heat transfer media. These media circulate in the heating pipes, transferring the heat energy to radiators or underfloor heating systems, thereby achieving heating. In an electric heating boiler, electrical energy is converted into heat energy through heating elements, which can be ceramic or stainless steel heating elements, etc.
[0005] Furthermore, most modern boilers are equipped with intelligent control systems, allowing users to remotely operate them via a mobile app or smart remote control, enabling functions such as timed on / off switching and temperature adjustment, greatly enhancing convenience. These intelligent features make boilers more suitable for the needs of modern families and also improve energy efficiency.
[0006] Existing heating boilers include a boiler body, inside which are a burner and a heat exchanger. The burner burns and heats the boiler to produce high-temperature flue gas, which in turn heats the cold water entering the heat exchanger. The high-temperature flue gas is discharged from the boiler body through the flue gas holder and the flue gas pipe. When the high-temperature flue gas forms condensate in the flue gas pipe, it drips down the flue gas pipe into the flue gas holder, forming backflow water that flows back into the boiler body. This can easily cause moisture damage to the internal parts of the heating boiler.
[0007] Therefore, it is necessary to design a structure for collecting condensate and backflow water from the heating boiler. Utility Model Content
[0008] This utility model proposes a condensate and backflow water collection structure for a heating furnace. The heating furnace is equipped with a drainage and water collection assembly connected to the flue gas assembly. When high-temperature flue gas forms condensate in the flue gas assembly, and when the condensate flows back into the heating furnace along the flue gas assembly to form backflow water, the liquid flows back into the water collection tank along the drainage channel to collect the condensate and backflow water of the heating furnace, thereby protecting the internal structure of the heating furnace and preventing the internal structure of the heating furnace from being easily damp.
[0009] A heating boiler condensate and backflow water collection structure designed for this purpose includes a diversion and water collection assembly installed inside the heating boiler and connected to the flue gas assembly. The diversion and water collection assembly is provided with a diversion channel connected to the flue gas assembly and a water collection tank connected to the diversion channel. Liquid on the flue gas assembly flows back into the water collection tank along the diversion channel to collect the condensate and backflow water of the heating boiler.
[0010] The heating furnace includes a heating furnace top plate, and the water diversion assembly includes a diversion plate module connected to the heating furnace top plate, with a diversion channel disposed on the diversion plate module.
[0011] The diversion plate module includes a first diversion plate, which has a connecting block that abuts against the inner side of the top plate of the heating furnace.
[0012] The diversion plate module also includes a second diversion plate connected to the first diversion plate. The first diversion plate is provided with an installation groove for installing the second diversion plate. The second diversion plate is provided with an opening groove that extends vertically through the second diversion plate. A diversion groove is formed between the inner circumferential side of the opening groove of the second diversion plate and the inner bottom wall of the installation groove.
[0013] The bottom wall of the mounting groove is provided with a drainage hole for connecting to the water receiving trough;
[0014] The bottom wall of the mounting groove is provided with a number of circumferentially spaced drainage holes.
[0015] A first sealing element is provided between the second diversion plate and the inner bottom wall of the mounting groove, and the gap between the second diversion plate and the inner bottom wall of the mounting groove forms a sealing fit through the first sealing element.
[0016] The exhaust assembly includes an exhaust pipe, a first through hole on the top plate of the heating furnace, a second through hole that runs vertically through the first diversion plate, and a positioning part that inserts into the first through hole and the second through hole on the exhaust pipe.
[0017] The smoke exhaust assembly includes a smoke exhaust pipe and a smoke exhaust seat connected to the smoke exhaust pipe, and the smoke exhaust seat is provided with a notch for communicating with the drainage groove;
[0018] The smoke exhaust holder has several circumferentially spaced notches.
[0019] The water diversion and receiving assembly includes a water receiving plate with a baffle on it. A water receiving groove is formed between the inner periphery of the baffle and the inner bottom wall of the water receiving plate. One end of the water receiving groove is provided with a drain end for connecting a drain pipe, and the drain end extends downward toward the bottom of the water receiving groove.
[0020] The inner bottom wall of the water receiving plate is provided with several spaced diversion blocks corresponding to the drainage end, and a drainage gap is formed between two adjacent diversion blocks to connect the drainage end.
[0021] The exhaust assembly includes an exhaust pipe, a water receiving plate with a third through hole corresponding to the exhaust pipe, an annular protrusion on the inner bottom wall of the water receiving plate corresponding to the third through hole, the annular protrusion extending upward from the inner bottom wall of the water receiving plate, the exhaust pipe being inserted into the third through hole, and a second sealing element being provided between the outer periphery of the exhaust pipe and the inner periphery of the third through hole.
[0022] The beneficial technical effects of this utility model are as follows:
[0023] The heating furnace is equipped with a drainage and water collection assembly that connects to the flue gas assembly. When high-temperature flue gas forms condensate in the flue gas assembly, and when the condensate flows back into the heating furnace along the flue gas assembly to form backflow water, the liquid flows back into the water collection tank along the drainage channel to collect the condensate and backflow water of the heating furnace, protect the internal structure of the heating furnace, and prevent the internal structure of the heating furnace from being easily damp.

[0033] The heating boiler includes a boiler body 26, and a premixed burner 27 is installed inside the boiler body 26. The premixed burner 27 is existing technology and contains a heat exchanger and a burner. The top of the premixed burner 27 is provided with a flue gas outlet that connects to the flue gas exhaust assembly 1. The high-temperature flue gas generated by the combustion heating of the burner enters the flue gas exhaust assembly 1 through the flue gas outlet.
[0034] When the high-temperature flue gas in the flue gas assembly 1 cools and forms condensate, the condensate flows back along the flue gas assembly 1 into the diversion groove 3 of the diversion and water collection assembly 2, and then into the water collection groove 4 to collect the boiler condensate and backflow water.
[0035] The heating furnace includes a heating furnace top plate 5, and the water diversion assembly 2 includes a diversion plate module 6 connected to the heating furnace top plate 5, with a diversion channel 3 disposed on the diversion plate module 6.

[0037] In this embodiment, the top of the first diversion plate 7 is provided with an upwardly extending extension block, one end of which is bent toward the inside of the first diversion plate 7 to form a connecting block 8. Connecting blocks 8 are provided on both sides of the top of the first diversion plate 7.
