In the overall structure of a wall-hung boiler, the combustion chamber is one of the most critical core components. Among the wall-hung boiler products commonly found on the market, the vast majority adopt the traditional single-chamber combustion chamber structure. The heating efficiency of a single-chamber combustion chamber is relatively low and cannot meet people's needs.
[0003] The prior art patent document CN208671327U provides a segmented combustion chamber for a wall-hung boiler. By dividing the combustion chamber into multiple combustion chambers with multiple baffles, the circulating water pipes are heated, which greatly improves the heating efficiency and heating effect of the wall-hung boiler.
[0004] The existing technology described above heats the circulating water pipe by dividing it into multiple combustion chambers. However, during the heating process, the circulating water pipe is placed above the combustion pipe with a single pipe body. The water flows through the pipe at a relatively fast speed, making it difficult to fully absorb heat. This device cannot effectively prolong the residence time of water in the circulating water pipe, resulting in poor heating effect and low thermal efficiency. Therefore, we need a segmented combustion chamber for wall-hung boilers. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a segmented combustion chamber for a wall-hung boiler, including a combustion chamber, wherein two partitions are fixedly connected to the inner wall of the combustion chamber, and the two partitions divide the combustion chamber into three combustion chambers, wherein a heating component is provided inside the combustion chamber, and a collection component is provided on the inner wall of the combustion chamber.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figure 1-4As shown, a segmented combustion chamber of a wall-mounted boiler includes a combustion chamber 1. Two partitions 2 are fixedly connected to the inner wall of the combustion chamber 1, dividing it into three combustion chambers 3. A heating assembly 4 is installed inside each combustion chamber 3, and a collection assembly 5 is installed on the inner wall of each combustion chamber 3. The heating assembly 4 includes a spiral circulating water pipe 401, with an inlet pipe 402 at one end and an outlet pipe 403 at the other end. A gas distribution pipe 404 is installed on one side of the combustion chamber 1. A gas pipe 405 is fixedly connected to the outer wall of 404, an air pipe 406 is fixedly connected to the inner wall of the combustion chamber 1, and an ignition needle 407 is provided on the inner wall of the combustion chamber 1; the collection assembly 5 includes a slide groove 501, and a collection tray 502 is slidably connected to the inner wall of the slide groove 501. A circular groove 503 is opened on the inner wall of the collection tray 502, and a spring 504 is fixedly connected to the inner wall of the circular groove 503. A round head 505 is fixedly connected to one end of the spring 504. A sealing groove 506 is opened on the inner wall of the collection tray 502, and a sealing ring 507 is provided on the inner wall of the sealing groove 506.
[0025] Through the above technical solution, the spiral circulating water pipe 401 increases the contact area and time between water and combustion heat. When the gas pipe 405 delivers gas, the gas mixes with the air input through the air pipe 406 and is ignited by the ignition needle 407. The heat generated by combustion heats the water in the spiral circulating water pipe 401. The water in the three spiral circulating water pipes 401 is heated sequentially by the three independent combustion chambers 3, allowing the water to gradually heat up, improving heating efficiency and meeting people's needs. The collection tray 502 can collect impurities generated by combustion. The collection tray 502 can be pulled out from the slide groove 501 by the handle to clean the collected impurities without complicated disassembly, which is convenient for maintenance. The sealing ring 507 enhances the sealing performance and prevents impurity leakage. The round head 505 is pressed against the inner wall of the combustion chamber 1 by the elastic force of the spring 504, making the collection tray 502 more stable in the slide groove 501 and less likely to fall off.
[0026] Specifically, the inner wall of the combustion chamber 1 is fixedly connected to a smoke exhaust branch pipe 6, and one end of the smoke exhaust branch pipe 6 is fixedly connected to a main smoke exhaust pipe 7.
[0027] Through the above technical solution, the flue gas generated by combustion enters the main exhaust pipe 7 from the exhaust branch pipe 6 and is discharged from the main exhaust pipe 7; one end of the air pipe 406 is connected to a fan through a pipe, and air is delivered by the fan; an observation window is provided on the outer wall of the combustion chamber 1.
[0028] Specifically, there are three spiral circulating water pipes 401, and the three spiral circulating water pipes 401 are respectively installed in three combustion chambers 3, and the three spiral circulating water pipes 401 are connected to each other by water pipes.
[0029] The above technical solution facilitates water flow by allowing water to enter the middle second spiral circulating water pipe 401 from the first spiral circulating water pipe 401 below.
[0030] Specifically, one end of the gas pipe 405 passes through the combustion chamber 1 and extends into the spiral circulating water pipe 401.
[0031] Through the above technical solution, after the gas ejected from the gas pipe 405 is burned, the long flame heats the water in the spiral circulating water pipe 401.
[0032] Specifically, the combustion chamber 1 forms a sliding structure with the collection plate 502 via the groove 501, and the outer wall of the collection plate 502 is in contact with the inner wall of the groove 501.
[0033] The above technical solution enhances the connection between the combustion chamber 1, the slide 501, and the collection plate 502, making it easier for the collection plate 502 to slide within the slide 501 and improving stability.
[0034] Specifically, the collecting tray 502 forms an elastic structure with the spring 504 and the round head 505, and one end of the round head 505 extends into the round groove 503 and is connected to the spring 504.
[0035] With the above technical solution, when the collection tray 502 is inserted into the slide groove 501 for installation, the inner wall of the slide groove 501 presses against the round head 505, causing it to move. The movement of the round head 505 drives the spring 504 to contract. The spring 504 contracts and rebounds. The round head 505 presses against the inner wall of the slide groove 501 through the elastic force of the spring 504, making the sliding installation of the collection tray 502 more stable and less likely to fall off.
[0036] Specifically, the inner wall shape and size of the sealing groove 506 match the outer wall shape and size of the sealing ring 507, and the inner wall of the sealing groove 506 fits into the outer wall of the sealing ring 507.
[0037] The above technical solution enhances the connection between the sealing groove 506 and the sealing ring 507. By providing the sealing ring 507, the sealing performance at the connection between the collecting tray 502 and the slide 501 is strengthened, preventing leakage of impurities and gases.
[0038] In operation, external gas first enters gas pipe 405 through gas distribution pipe 404. Gas pipe 405 delivers gas to the three combustion chambers 3. External air enters the three combustion chambers 3 through air pipe 406 and is ignited by ignition needle 407. The high-temperature flame generated by combustion heats the water in the spiral circulating water pipe 401. The water flows through inlet pipe 402 and first enters the first spiral circulating water pipe 401 below. After absorbing the heat of combustion and initially heating up in the first spiral circulating water pipe 401, the water flows through the water pipe into the second spiral circulating water pipe in the middle, where it continues to be heated up, and then flows into the upper spiral circulating water pipe. The third spiral circulating water pipe 401 completes the third heating, achieving a gradual increase in temperature, and finally flows out from the outlet pipe 403, improving heating efficiency and effect. The flue gas generated by combustion enters the main exhaust pipe 7 through the exhaust branch pipe 6 and is discharged from the main exhaust pipe 7. The collection plate 502 can collect the impurities generated by combustion. When cleaning is required, the operator can pull the collection plate 502 by the handle to pull the collection plate 502 out of the slide 501, and then process the collected impurities. This completes all the work. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
