Description

Technical Field

[0001] This utility model belongs to the field of wall-hung boiler technology, specifically, it relates to a new type of wall-hung boiler for underfloor heating systems in self-built rural houses. Background Technology

[0002] With the development of the rural economy and the improvement of living standards, the demand for winter heating in rural self-built houses is increasing. Underfloor heating systems, as an efficient and comfortable heating method, are gradually being widely used in rural self-built houses. However, traditional wall-hung boiler underfloor heating systems have some problems during use, limiting their further promotion and application in rural areas.

[0003] Wall-hung boilers generate a large amount of high-temperature exhaust gas during combustion, which contains abundant waste heat resources. However, in traditional systems, this waste heat is often directly released into the atmosphere, resulting in energy waste, increased carbon emissions, and adverse environmental impacts. Secondly, the power supply in rural areas is relatively unstable, with frequent power outages. During power outages, the electrical control system of the wall-hung boiler cannot function properly, causing the entire heating system to fail and severely impacting residents' quality of life. Furthermore, the inspection and maintenance of wall-hung boilers usually require professional personnel, which not only increases maintenance costs but may also lead to equipment failure due to untimely inspections, affecting heating efficiency. Therefore, there is a need for a new type of wall-hung boiler that offers good heating performance, is easy to maintain, and has low maintenance costs for underfloor heating systems in self-built rural houses.

The first sliding hole 54 is horizontally arranged on the L-shaped fixing plate 51, and the second sliding hole 516 is vertically arranged on the L-shaped fixing plate 51. The first bevel gear 58 is located at the right end of the first screw 57, and the second bevel gear 513 is located at the left end of the second screw 512. The first bevel gear 58 and the second bevel gear 513 are arranged opposite each other.

The rear end of the third screw 511 passes through the rotating hole on the rear side wall of the L-shaped fixing plate 51. The external threads of the first screw 57 and the second screw 512 are in the same direction. The first bevel gear 58, the second bevel gear 513 and the third bevel gear 59 mesh with each other. The first sliding plate 53 is located on the first slider 52. The first slider 52 is threadedly connected to the first screw 57. The second sliding plate 515 is located on the second slider 514.

Rotating the knob 55 causes the third screw 511 to rotate, which in turn causes the third slider 510 to slide inside the second sliding hole 516. This causes the third sliding plate 56 to move forward closer to the boiler body 1. Furthermore, the rotation of the third screw 511 causes the third bevel gear 59 to rotate, which in turn causes the second bevel gear 513 and the first bevel gear 58 to rotate, further driving the second screw 512 and... When the first screw 57 rotates, the second screw 512 rotates, causing the second slider 514 to move to the left along the first sliding hole 54, which in turn causes the second sliding plate 515 to move to the left and closer to the wall-mounted boiler body 1. The first screw 57 causes the first slider 52 to move to the right along the first sliding hole 54, which in turn causes the second sliding plate 515 to move to the right and closer to the wall-mounted boiler body 1. Tightening the knob 55 causes the first sliding plate 53, the second sliding plate 515, and the third sliding plate 56 to clamp the wall-mounted boiler body 1 with the wall 8, thus completing the installation of the wall-mounted boiler body 1. When disassembly is required, rotating the knob 55 in the opposite direction will loosen the first sliding plate 53, the second sliding plate 515, and the third sliding plate 56 from the wall-mounted boiler body 1, which is convenient and quick.

[0027] This invention utilizes a waste heat recovery and utilization mechanism 9 to introduce high-temperature waste gas generated by the wall-hung boiler into an S-shaped pipe 911 within a water tank 910. The waste heat from the waste gas is then used to heat the water, achieving effective recovery and reuse of waste heat.

After being heated in the water tank 910, the waste gas further enters a filter box 92, where activated carbon adsorption balls purify harmful substances, reducing environmental pollution and meeting environmental protection requirements. The recovered hot water can be directly used through a tap 99, providing additional hot water for the household and increasing the system's functionality and practicality.

[0028] This invention utilizes a photovoltaic power generation mechanism 3 to convert solar energy into electrical energy using solar photovoltaic panels, which is then stored in a storage battery 33. During power outages, the storage battery 33 can provide backup power to the boiler's electrical system via an inverter 38, ensuring the heating system's normal operation and improving system reliability and stability.
