[0002] Condensing hot water boilers are high-efficiency boiler devices primarily used for providing hot water and heating. Their main difference from traditional hot water boilers lies in their ability to recover heat generated during combustion and reuse this heat to heat water, thereby improving energy efficiency. Their working principle utilizes condensation technology to condense water vapor in exhaust gases into water, releasing latent heat. This latent heat is recovered and used to heat cold water, thus improving the boiler's thermal efficiency. Condensing hot water boilers are energy-saving and environmentally friendly heating equipment, especially suitable for locations requiring long-term, stable heating and hot water supply.

[0003] Existing boilers lack automatic cleaning mechanisms, leading to excessive dust accumulation in the combustion chamber, which affects combustion efficiency and the boiler's heat transfer performance. Traditional boiler cleaning and maintenance often require frequent manual intervention, increasing operating and maintenance costs. Furthermore, the cleaning device lacks stable support, resulting in instability during operation or uneven cleaning effects, thus impacting the overall boiler efficiency. Therefore, this invention proposes a condensing commercial hot water boiler to address the problems mentioned in the background. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4 A condensing commercial hot water boiler includes a boiler body 1, which includes an internal combustion chamber 18. An inlet is provided on the front side of the combustion chamber 18, and a sealing seat 2 is installed at the inlet. A mechanical lock 3 is provided between the sealing seat 2 and the outer shell of the combustion chamber 18. A device seat 4 corresponding to the sealing seat 2 is provided on the front side of the boiler body 1. A rotating shaft 8 located inside the combustion chamber 18 is rotatably connected to the front side of the device seat 4. Several scrapers 9 are evenly fixed around the rotating shaft 8. The sealing seat 2 is rotatably installed on the front side of the combustion chamber 18. When it is necessary to clean the smoke and dust inside the combustion chamber 18, the sealing seat 2 is turned open and the sealing seat 2 is restricted to a flat position. The device seat 4 is pushed into the combustion chamber 18 of the boiler body 1, and the rotating shaft 8 and several scrapers 9 around it are pushed into the combustion chamber 18.

[0024] Furthermore, the upper side of the device base 4 corresponds to the inlet shape of the combustion chamber 18. The shape range of the scraper 9 is smaller than that of the front inlet of the combustion chamber 18, and the length of the scraper 9 is less than or equal to the inner diameter of the combustion chamber 18. The interior of the combustion chamber 18 is cylindrical, and the rotating shaft 8 is located at the axis of the combustion chamber 18. The side of the scraper 9 has a fan-shaped protrusion, the lower side of the scraper 9 has a bevel, and a collection groove is opened inside the scraper 9. The device base 4 is equipped with a drive device connected to the rotating shaft 8. After the front cleaning structure of the device base 4 is inserted into the combustion chamber 18, the drive device inside the device base 4 is started to drive the connected rotating shaft 8 to rotate. During the rotation, several scrapers 9 around the rotating shaft 8 clean the interior of the combustion chamber 18 through the bevel on their lower side. After the inner wall is cleaned, the rotating shaft 8 structure on the front side of the device base 4 is pulled out of the combustion chamber 18, and the dust swept off is swept out through the collection groove inside the scraper 9 to ensure the cleanliness of the interior of the combustion chamber 18.

[0025] Furthermore, support strips 10 are provided on both the left and right sides of the device base 4, and a support frame 12 is provided between the device base 4 and the lower closed seat 2. A slider 13 that slides up and down is provided on the outer side of the device base 4. The slider 13 is rotatably connected to the upper end of the support frame 12, and a double-sided toothed block 5 is rotatably connected to the lower end of the support frame 12. A rotating rod 14 is rotatably connected to the upper side of the slider 13. A limit knob 15 is fixed to the upper end of the rotating rod 14. A limit block 16 corresponding to the limit knob 15 is fixed to the outer side of the device base 4. A compression spring 17 is sleeved around the rotating rod 14, and the upper end of the rotating rod 14... A limiting block corresponding to the compression spring 17 is provided. The limiting block is fixed on the outside of the device base 4, and the rotating rod 14 passes through the limiting block. The outer end of the double-sided toothed block 5 is fixed with an insert plate 6. The inner side of the closed seat 2 is provided with a sleeve 7 corresponding to the insert plate 6. The support bar seat 10 is rotatably connected to the left and right sides of the device base 4. A spur gear 11 is fixed at the junction of the support bar seat 10, and both spur gears 11 mesh with the middle double-sided toothed block 5. Before assembling the structure of the device base 4 with the front side of the combustion chamber 18, the device base 4 needs to be tightly connected to the boiler body 1 to ensure the stability of the structure during operation.

[0026] Furthermore, the upper limit knob 15 of the rotating rod 14 is rotated. The limit knob 15 has a slot corresponding to the rotating rod 14 and the limit knob 15. The limit knob 15 and the rotating rod 14 pass through the limit knob 15. Since the structure of the rotating rod 14 is no longer restricted by the limit block 16, the compression spring 17 compresses the slider 13 downward. The slider 13 compresses the insert plate 6 to move backward through the lower support frame 12. This causes the insert plate 6 at the rear end of the double-sided toothed block 5 to enter the corresponding sleeve 7 in the flattened closed seat 2. During the backward movement of the double-sided toothed block 5, the spur gears 11 meshing on both sides of the double-sided toothed block 5 rotate. The spur gears 11 rotate towards the center, so that the outer ends of the two support bar seats 10 are tightly attached to the outer side of the boiler body 1. The support bar seats 10 on both sides abut against the boiler body 1 and the support frame 12 that supports vertically in the middle can ensure the stable state of the device base 4 structure during operation.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
