Description

Technical Field

[0001] This utility model relates to an inner box cover, and more particularly to an inner box cover structure used in wall-hung boilers. Background Technology

[0002] As is well known, the inner tank cover of a wall-hung boiler refers to the cover installed inside the boiler to protect internal components and prevent dust from entering. It is usually made of metal or plastic and functions as a dustproof, waterproof, and protective cover for internal components. The design and installation method of the inner tank cover vary depending on the brand and model, but the basic functions are similar. The inner tank cover of a wall-hung boiler is generally located on the outside of the combustion chamber, serving as heat insulation and protection. However, in practice, due to the airflow during combustion, the flat inner tank cover, due to insufficient strength, can vibrate, causing abnormal noises in the entire boiler. This is a major drawback of the existing technology. Utility Model Content

[0003] The technical solution adopted by this utility model is as follows: an inner box cover plate for a wall-hung boiler, the inner box cover plate being installed in the wall-hung boiler, the wall-hung boiler including a combustion chamber, an inner frame and a front panel, wherein the combustion chamber is installed in the wall-hung boiler, the inner box cover plate is installed in front of the combustion chamber, the combustion chamber is sealed in the wall-hung boiler by means of the inner box cover plate, the inner frame is installed on the inner box cover plate, and the front panel is connected to the inner frame.

[0004] The inner frame includes an outer frame and a crossbeam, which is fixedly connected to the outer frame. The inner box cover is provided with an outer protrusion structure, which includes an outer protrusion structure and several protrusion structures. The outer protrusion structure is circumferentially arranged on the inner box cover. The inner side of the outer protrusion structure is an inner sheet metal area, and the outer side of the outer protrusion structure is an outer sheet metal area. Several protrusion structures are located on the inner sheet metal area, and a flat plate area is formed at the center of the several protrusion structures. A shock-absorbing fixing block is pressed on the flat plate area.

[0005] The beneficial effects of this utility model are as follows: The inner box cover plate of this utility model is provided with an outward protrusion structure, which can increase the rigidity of the sheet metal of the inner box cover plate and reduce the abnormal noise caused by sheet metal vibration during the intake combustion process. This utility model fits the shock-absorbing fixing block on the inner frame, uses the cover plate pressure pad to press on the flat area of ​​the inner box cover plate, and uses the panel pressure pad to press on the inner side of the front panel. Its structure can further alleviate the abnormal noise caused by vibration of the inner box cover plate and the front panel. Attached Figure Description

[0010] like Figures 1 to 4 As shown, an inner box cover 100 of a wall-hung boiler is disposed in a wall-hung boiler 200. The wall-hung boiler 200 includes a combustion chamber 210, an inner frame 220, and a front panel 230. The combustion chamber 210 is disposed in the wall-hung boiler 200, and the inner box cover 100 covers the front of the combustion chamber 210, thereby enclosing the combustion chamber 210 in the wall-hung boiler 200. The inner frame 220 is covered on the inner box cover 100, and the front panel 230 is connected to the inner frame 220.

[0011] The inner frame 220 includes an outer frame 221 and a crossbeam 222, which is fixedly connected to the outer frame 221.

[0012] The inner box cover 100 is provided with an outward protrusion structure 300, which can increase the rigidity of the sheet metal of the inner box cover 100 and reduce the abnormal noise caused by sheet metal vibration during the intake combustion process.

[0013] The external convex structure 300 includes an outer convex structure 310 and several protrusion structures 320. The outer convex structure 310 is arranged around the inner box cover plate 100. The inner side of the outer convex structure 310 is an inner sheet metal area 410, and the outer side of the outer convex structure 310 is an outer sheet metal area 420. Several protrusion structures 320 are located on the inner sheet metal area 410, and a flat plate area 430 is formed at the center of the several protrusion structures 320. In specific implementation, each protrusion structure 320 is an isosceles triangle.

[0014] A shock-absorbing fixing block 500 is pressed onto the flat plate area 430. The shock-absorbing fixing block 500 is made of heat-resistant elastic material, such as heat-resistant rubber or heat-resistant silicone.

[0015] The shock-absorbing fixing block 500 includes a cover plate pressure pad 510, a panel pressure pad 520, and a crossbeam sleeve 530. The crossbeam sleeve 530 is fitted onto the crossbeam 222 of the inner frame 220. The cover plate pressure pad 510 and the panel pressure pad 520 are respectively fixedly connected to the upper and lower ends of the crossbeam sleeve 530. The cover plate pressure pad 510 presses against the flat plate area 430 of the inner box cover plate 100, and the panel pressure pad 520 presses against the inner side surface 231 of the front panel 230.

[0016] This utility model fits the shock-absorbing fixing block 500 onto the inner frame 220, presses the cover plate pad 510 onto the flat area 430 of the inner box cover 100, and presses the panel pad 520 onto the inner side 231 of the front panel 230, which can further alleviate the abnormal noise caused by vibration of the inner box cover 100 and the front panel 230.
