Description

Technical Field

[0001] This utility model belongs to the field of wall-hung boiler technology, specifically relating to an air outlet structure for a wall-hung boiler. Background Technology

[0002] Wall-hung boilers, as a common heating and hot water supply equipment, are widely used in various building environments such as homes and offices. During the operation of a wall-hung boiler, the smooth discharge of flue gas is a key factor in ensuring its efficient and safe operation. The air outlet structure is the core component for realizing flue gas discharge, and its performance directly affects the overall operating effect and service life of the wall-hung boiler. The air outlet structure of a traditional wall-hung boiler mainly consists of a smoke hood, a fan, an air outlet pipe, and a flue pipe interface. The fan air outlet pipe is inserted into the connecting pipe on the inner wall of the wall-hung boiler to form a channel for flue gas discharge.

[0003] However, existing wall-hung boiler air outlet structures have shortcomings in practical applications: traditional wall-hung boilers have fixed internal pipe connections. In daily use, when it's necessary to disassemble, maintain, or repair the fan in the air outlet structure, the fan cannot be moved downwards due to the obstruction of the fume hood. Furthermore, the fixed internal pipe connections restrict the extraction path of the fan's air outlet pipe. This means that when disassembling or assembling the fan, operators must first remove the fixed internal pipe connections before they can disassemble or assemble the fan. This process is cumbersome, complex, and time-consuming. In addition, the frequent dismantling and installation of fixed pipes can damage the connection between the pipe and the inner wall of the wall-hung boiler, affecting the overall structural stability of the boiler and increasing later maintenance costs. Furthermore, traditional air outlet structures are also inadequate in terms of the sealing of the connection between the fan outlet pipe and the pipe. Due to the lack of an effective sealing design, flue gas may leak from the connection between the outlet pipe and the pipe during long-term operation of the wall-hung boiler. This will not only cause heat loss and reduce the heating efficiency of the wall-hung boiler, but may also lead to the leakage of harmful gases into the room. Therefore, this utility model proposes an air outlet structure for wall-hung boilers. Utility Model Content

[0004] The purpose of this invention is to provide an air outlet structure for a wall-hung boiler to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wall-hung boiler air outlet structure, including a smoke collection hood fixed to the top of the combustion chamber, a fan installed on the front surface of the smoke collection hood, an air outlet pipe disposed at the fan outlet, and a flue pipe interface fixed to the top surface of the boiler body and positioned corresponding to the air outlet pipe, and further including...

[0007] And a movable structure set between the telescopic air outlet pipe and the smoke exhaust pipe interface;

[0008] And a tight-fitting sealing structure is installed between the air outlet duct and the telescopic air outlet pipe.

[0009] Preferably, the movable structure includes an annular movable groove formed on the inner wall of the exhaust pipe interface for the top of the telescopic air outlet pipe to slide, and a plurality of springs are connected between the annular movable groove and the top of the telescopic air outlet pipe.

[0011] Preferably, it also includes an insertion port that runs through the top surface of the furnace body to allow the telescopic air outlet pipe to pass through smoothly, and the insertion port corresponds to the position of the annular movable groove.

[0012] Preferably, the abutting sealing structure includes an annular seat fixed to the top surface of the air outlet pipe, an annular rubber seat embedded in the top surface of the annular seat, an annular sealing protrusion on the top surface of the annular rubber seat, and an annular sealing groove corresponding to the annular sealing protrusion on the bottom surface of the telescopic air outlet pipe.

[0015] Preferably, the surface of the fan is fixed with multiple fixing feet, and the fixing feet are fixed to the smoke hood by screws.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: The wall-hung boiler air outlet structure of this application, by setting a telescopic air outlet pipe at the interface of the wall-hung boiler inner wall, and cooperating with the fan air outlet pipe, completely changes the inconvenience of the traditional fixed air outlet pipe when disassembling and assembling the fan. Operators can easily complete the disassembly and maintenance of the fan without removing the air outlet pipe on the inner wall of the wall-hung boiler, which greatly shortens the disassembly and assembly time and reduces the difficulty of disassembly and maintenance of the air outlet structure. The design of the tight sealing structure effectively solves the problem of poor connection sealing of the traditional air outlet structure, which can reliably prevent flue gas leakage and ensure the stable operation of the air outlet structure.

Detailed Implementation

[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. 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.

[0023] Example

[0024] Please see Figures 1 to 4 This is an embodiment of the present utility model, which provides the following technical solution: a wall-hung boiler air outlet structure, including a smoke collection hood 1 fixed to the top of the combustion chamber 7 by multiple bolts, a fan 2 installed on the front surface of the smoke collection hood 1, an air outlet pipe 3 set at the air outlet of the fan 2, and a smoke exhaust pipe interface 4 fixed to the top surface of the boiler body 6 by multiple screws and positioned corresponding to the air outlet pipe 3. The above structures are common structures of existing wall-hung boilers. The specific structural principles will not be elaborated here. Simply put, the smoke collection hood 1 covers the top of the combustion chamber 7 and can collect the flue gas in the combustion chamber 7. The front surface of the smoke collection hood 1 has a round hole corresponding to the air inlet of the fan 2, so that when the fan 2 is running, the flue gas inside the smoke collection hood 1 can be discharged through the air outlet pipe 3 to complete the air outlet of the wall-hung boiler, that is, the smoke exhaust.

[0025] Also includes

[0026] The retractable air outlet pipe 5 is located at the bottom of the flue pipe interface 4 and extends through the bottom end to the inside of the furnace body 6. The top end of the air outlet pipe 3 is inserted into the inside of the bottom end of the retractable air outlet pipe 5, thus connecting the air outlet pipe 3 with the flue pipe interface 4. This allows the flue gas discharged from the air outlet pipe 3 to be smoothly discharged to the outside of the furnace body 6 through the retractable air outlet pipe 5 and the flue pipe interface 4. The retractable design of the retractable air outlet pipe 5 makes it easy to remove the fan 2 for maintenance. Simply remove the fixing screws between the fan 2 and the smoke hood 1, and then push the bottom end of the retractable air outlet pipe 5 upwards to separate the bottom end of the retractable air outlet pipe 5 from the air outlet pipe 3. The fan 2 and the air outlet pipe 3 can then be moved forward and removed directly, greatly improving the convenience of disassembly and maintenance.

[0027] And a movable structure set between the telescopic air outlet pipe 5 and the smoke exhaust pipe interface 4 to realize the telescopic movement of the telescopic air outlet pipe 5;

[0028] And a tight-fitting sealing structure is set between the air outlet duct 3 and the telescopic air outlet pipe 5 to achieve effective sealing at the connection between the two during daily use.

[0029] In this embodiment, preferably, the movable structure includes an annular movable groove 41 formed on the inner wall of the exhaust pipe interface 4 for the top of the telescopic air outlet pipe 5 to slide. Multiple springs 42 are connected between the annular movable groove 41 and the top of the telescopic air outlet pipe 5, so that the telescopic air outlet pipe 5 is always subjected to the downward pushing force of multiple springs 42 during daily use, ensuring that the bottom end of the telescopic air outlet pipe 5 is stably fitted onto the top of the air outlet pipe 3, and ensuring the connection stability between the telescopic air outlet pipe 5 and the air outlet pipe 3.

[0030] In this embodiment, preferably, the top surface of the telescopic air outlet pipe 5 is provided with a plurality of cylindrical slots for the spring 42 to be inserted. The bottom end of the spring 42 is inserted into the cylindrical slot, so that the spring 42 is limited and prevents the spring 42 from deviating or falling off.

[0031] In this embodiment, preferably, it also includes an insertion port 61 that is opened through the top surface of the furnace body 6 so that the telescopic air outlet pipe 5 can pass through smoothly, and the insertion port 61 corresponds to the position of the annular movable groove 41.

[0032] In this embodiment, preferably, the tight-fitting sealing structure includes an annular seat 31 welded and fixed to the top surface of the air outlet pipe 3, an annular rubber seat 33 embedded in the top surface of the annular seat 31, an annular sealing protrusion 34 provided on the top surface of the annular rubber seat 33, and an annular sealing groove 52 opened on the bottom surface of the telescopic air outlet pipe 5 corresponding to the annular sealing protrusion 34. During daily use, the top of the annular sealing protrusion 34 is squeezed into the annular sealing groove 52. Because the telescopic air outlet pipe 5 is always subjected to the downward force of multiple springs 42, the annular sealing protrusion 34 can be squeezed and undergo elastic deformation and be squeezed into the annular sealing groove 52 to form an annular sealing measure, ensuring the effective sealing of the connection between the telescopic air outlet pipe 5 and the air outlet pipe 3.

[0033] In this embodiment, preferably, the top surface of the annular seat 31 is provided with an annular groove 32 for the annular rubber seat 33 to be embedded and installed. The annular rubber seat 33 and the annular sealing protrusion 34 are an integral structure, both of which are made of fluororubber material and will undergo elastic deformation when squeezed.

[0034] In this embodiment, preferably, two levers 51 are symmetrically welded and fixed to the bottom surface of the telescopic air outlet pipe 5, which facilitates the subsequent operation of the operator to squeeze the levers 51 to push the telescopic air outlet pipe 5 upward.

[0035] In this embodiment, preferably, the surface of the fan 2 is welded with multiple fixing feet, and the fixing feet are fixed to the smoke hood 1 by screws.

[0036] In summary, when the fan 2 needs to be removed for maintenance and repair during subsequent maintenance of this air outlet structure, simply remove the fixing screws between the fan 2 and the smoke hood 1, then push the telescopic air outlet pipe 5 upwards until its bottom end separates from the air outlet pipe 3. At this point, the fan 2 can be directly moved forward and removed from the front of the smoke hood 1, effectively improving the ease of disassembly and assembly of the fan 2 and facilitating quick disassembly and maintenance in case of subsequent air outlet structure failures. When it is necessary to reinstall the fan 2 later, simply... First, align the air inlet of the fan 2 with the round hole on the surface of the smoke hood 1. Then, push the telescopic air outlet pipe 5 upward so that it no longer obstructs the air outlet pipe 3. At this point, press the fan 2 onto the front surface of the smoke hood 1 and align the air outlet pipe 3 with the telescopic air outlet pipe 5. Then, release the telescopic air outlet pipe 5 so that it returns to its original position under the push of the spring 42. Finally, the bottom end of the telescopic air outlet pipe 5 is fitted onto the top end of the air outlet pipe 3. Finally, tighten the fixing screws between the fan 2 and the smoke hood 1.

[0037] Although embodiments of the present invention have been shown and described (see the detailed description above), 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.
