Abstract
Description
Technical Field
[0001] This utility model relates to a self-adjusting structure, and in particular to a self-adjusting structure for a wall-hung boiler that includes the boiler body and an oxygen sensing and analysis structure. Background Technology
[0002] As is well known, gas-fired wall-hung boilers offer powerful central heating capabilities, meeting the heating needs of multiple rooms while also providing hot water for bathing. The insulation performance of a gas-fired wall-hung boiler is affected by local climate conditions and the building's insulation. In practice, buildings equipped with wall-hung boilers allow individual rooms to be set to comfortable temperatures as needed, and heating can be turned off in individual rooms as required. They also provide a large flow of constant-temperature hot water for bathing, kitchens, and other domestic uses. Due to these characteristics, wall-hung boilers are now widely used.
[0003] However, wall-hung boilers typically require pre-calibration under standard combustion conditions during production. This pre-calibration usually includes setting maximum power, minimum power, ignition power, and oxygen content. However, due to varying operating environments, such as changes in local gas composition and calorific value, flue length, and altitude, fully premixed wall-hung boilers may malfunction in actual use. When problems arise, specialized after-sales personnel with expensive flue gas analyzers are required for on-site adjustments. This not only increases operating costs but also necessitates a large number of professional after-sales personnel, causing significant inconvenience to users. This is a major drawback of the current technology. Utility Model Content

The boiler body includes a boiler control module, a flue pipe, and a communication interface. The boiler control module is located in the boiler body, the flue pipe is located at the top of the boiler body, and the communication interface is connected to the boiler control module and is located on the boiler body.
[0005] The oxygen sensing and analysis structure includes an oxygen sensing and analysis module, a flue gas detection and transmission channel, and a signal transmission channel. One end of the flue gas detection and transmission channel is connected to the oxygen sensing and analysis module, and the other end is connected to an oxygen sensing probe, which corresponds to the exhaust pipe and is detachably connected to the exhaust pipe. One end of the signal transmission channel is connected to the oxygen sensing and analysis module, and the other end is connected to the communication interface of the wall-mounted boiler body.
[0006] The beneficial effects of this utility model are as follows: The purpose of this utility model is to solve the problems of existing fully premixed wall-hung boilers failing to operate normally and incurring high debugging costs due to differences in operating environments and standard conditions. Specifically, it achieves the adjustment of the boiler's combustion conditions by setting up an oxygen sensing and analysis structure.
