[0040] The air duct structure provided in the embodiment of the present application is configured in the integrated stove, and the air duct structure can specifically be a back-sticking straight exhaust air duct structure. Figures 1 to 4 The air duct structure of the embodiment of the present application is described in detail.

[0041] The air duct structure of the embodiment of the present application includes an air duct enclosure 1, an air duct side panel 4, an air duct front panel 5 and an air duct cover plate 6, wherein the air duct enclosure 1 is arranged on the whole machine rear plate 2 of the integrated stove through a first connecting structure, and the air duct enclosure 1 defines an accommodating space for the volute assembly 3, and the height of the air duct enclosure 1 is less than the height of the whole machine rear plate 2.

[0042] It should be noted that, in the embodiment of the present application, the duct enclosure 1, the duct side panels 4 and the whole machine rear panel 2 are all formed from galvanized sheets, and the above-mentioned first connection structure is Tox riveting. Tox riveting is a special riveting method, the principle of which is to connect metal sheets together through high pressure to form a solid connection.

[0043] The air duct side panel 4 is connected to the top area 11 of the air duct enclosure 1 close to the rear panel 2 of the whole machine, and is connected to the rear panel 2 of the whole machine by Tox riveting.

[0044] The air duct front plate 5 is arranged on the outside of the air duct enclosure 1 opposite to the whole machine rear plate 2 to seal the accommodation space of the volute assembly 3 forward. Specifically, the air duct front plate 5 can be connected to the air duct enclosure 1 by screws.

[0045] The air duct cover plate 6 includes a transverse cover plate portion 61 and a vertical cover plate portion 62. The transverse cover plate portion 61 covers the remaining top area 12 of the air duct enclosure 1, and the vertical cover plate portion 62 extends upward from the side of the transverse cover plate portion 61 close to the rear plate 2 of the whole machine and is connected to the air duct side plate 4. Specifically, the transverse cover plate portion 61 can be connected to the remaining top area 12 of the air duct enclosure 1 by screws. The vertical cover plate portion 62 can be connected to the air duct side plate 4 by screws.

[0046] The air duct side plates 4 , the vertical cover plate portion 62 and the entire machine rear plate 2 define an air inlet cavity of the air duct structure.

[0047] In the specific implementation, Figure 1 As shown, the duct enclosure 1 is integrally formed by a mold, and includes a bottom enclosure portion, a left enclosure portion located on one side of the bottom enclosure portion, and a right enclosure portion located on the other side of the bottom enclosure portion. The bottom enclosure portion is arranged close to the lower edge of the rear plate 2 of the whole machine, and the left enclosure portion and the right enclosure portion extend from the bottom enclosure portion to the upper edge of the rear plate 2 of the whole machine to a preset position, respectively. There is a preset height difference between the preset position and the upper edge of the rear plate 2 of the whole machine, and the preset height difference is consistent with the height of the duct side plate 4.

[0048] The top of the left panel is stepped, and the top is recessed near the top area 11 of the rear panel 2 to form a left panel connection. For example, the extension length of the left panel connection can be 1 / 2 of the top length of the left panel. The top of the right panel is stepped, and the top is recessed near the top area 11 of the rear panel 2 to form a right panel connection. For example, the extension length of the right panel connection can be 1 / 2 of the top length of the right panel.

[0049] The duct side panel 4 includes a duct left side panel 41 and a duct right side panel 42. The duct left side panel 41 is connected to the duct enclosure 1 via the above-mentioned left side panel connection, and the duct right side panel 42 is connected to the duct enclosure 1 via the right side panel connection.

[0050] In some exemplary embodiments, see Figure 1 The left side plate 41 of the air duct is integrally formed by a mold, and includes a first front plate portion 411 , a first side plate portion 412 , a first bottom plate portion 413 and a first rear plate portion 414 .

[0051] Among them, the first end of the first bottom plate portion 413 is connected to the connection point of the left side plate, for example, it can be connected to the connection point of the left side plate by screws, and the second end of the first bottom plate portion 413 extends in a first direction, and the first direction is a direction with an acute angle to the horizontal direction. For example, the first direction can be a direction with an angle of 30°-60° to the horizontal direction.

[0052] The first rear plate portion 414 is disposed on one side of the first bottom plate portion 413 close to the whole machine rear plate 2, and is connected to the whole machine rear plate 2 through a first connection structure, namely, Tox riveting. The first front plate portion 411 is disposed on the other side of the first bottom plate portion 413 opposite to the first rear plate portion 414, and the first side plate portion 412 connects the first front plate portion 411 and the first rear plate portion 414 at a first end of the first bottom plate portion 413.

[0053] In some exemplary embodiments, see Figure 1 The right side plate 42 of the air duct is integrally formed by a mold, and includes a second front plate portion 421, a second side plate portion 422, a second bottom plate portion 423 and a second rear plate portion (not shown in the figure).

[0054] Among them, the first end of the second bottom plate portion 423 is connected to the connection point of the right side plate, for example, it can be connected to the connection point of the right side plate by screws, and the second end of the second bottom plate portion 423 extends in a second direction, and the second direction is a direction with an acute angle to the horizontal direction. For example, the second direction can be a direction with an angle of 30°-60° to the horizontal direction.

[0055] The second rear plate portion is arranged on one side of the second bottom plate portion 423 close to the whole machine rear plate 2, and is connected to the whole machine rear plate 2 by the first connection method, i.e., Tox riveting. The second front plate portion 421 is arranged on the other side of the second bottom plate portion 423 opposite to the second rear plate portion, and the second side plate portion 422 connects the second front plate portion 421 and the second rear plate portion at the first end of the second bottom plate portion 423.

[0056] In a specific embodiment, the vertical cover plate portion 62 is respectively connected to the first front plate portion 411 and the second front plate portion 421 through a detachable connecting structure, and the detachable connecting structure can be a screw connecting structure. For example, a first through hole is respectively provided on the first front plate portion 411 and the second front plate portion 421, and a second through hole matching the first through hole is provided on the vertical cover plate portion 62. The vertical cover plate portion 62 is connected to the first front plate portion 411 and the second front plate portion 421 by screws passing through the first through hole and the second through hole.

[0057] In some exemplary embodiments, see Figure 2 The connection between the left and bottom panels of the air duct panel 1 is a first rounded corner 13, and the connection between the right and bottom panels of the air duct panel 1 is a second rounded corner 14. In a specific implementation, for example, the first rounded corner 13 can be 120° or 150°, and the second rounded corner can be 120° or 150°.

[0058] Compared with the 90° right-angle design in the prior art, the first rounded corner and the second rounded corner avoid the adverse effects of the right angle on air intake and exhaust, making air intake and exhaust smoother, while increasing air volume and air pressure and reducing noise.

[0059] In some exemplary embodiments, see Figure 1 and Figure 2 The air duct structure also includes a left-side wire-passing plate 71 and a right-side wire-passing plate 72 for implementing electrical wiring.

[0060] Among them, the left side wire passing plate 71 includes a left side connecting portion and a left side wire passing portion, the left side connecting portion is connected to the first side plate portion 412 through a first connecting structure, namely Tox riveting, one side of the left side wire passing portion is arranged on the left side connecting portion, and the other side thereof extends in a direction away from the first side plate portion 412, and a wire passing hole (not shown in the figure) is provided on the left side wire passing portion, and the wire passing hole allows the electrical circuit to pass through.

[0061] The right side wire passing plate 72 includes a right side connecting portion and a right side wire passing portion, the right side connecting portion is connected to the second side plate portion 422 by a first connecting structure, namely Tox riveting, one side of the right side wire passing portion is arranged on the right side connecting portion, and the other side thereof extends in a direction away from the second side plate portion 422, and a wire passing hole (not shown in the figure) is also provided on the right side wire passing portion, which allows electrical circuits to pass through.

[0062] In a specific implementation, the left wire plate 71, the right wire plate 72, the air duct left plate 41 and the air duct right plate 42 can be formed by a mold based on a galvanized sheet, and then the left connecting portion of the left wire plate 71 is completely fitted with the first side plate portion 412 of the air duct left plate 41 and connected by Tox riveting, and the right connecting portion of the right wire plate 72 is completely fitted with the second side plate portion 422 of the air duct right plate 42 and connected by Tox riveting. Figure 3 The dotted box in the middle shows a distribution diagram of the Tox riveting points on the left side. The distribution of the Tox riveting points on the right side is similar to that on the left side, and thus the distribution of the Tox riveting points on the right side is not illustrated.

[0063] Exemplarily, the left side wire-passing portion of the left side wire-passing plate 71 may further include first supporting portions (not shown in the figure) arranged on both sides, wherein the first supporting portion close to the rear plate 2 of the whole machine may be connected to the rear plate 2 of the whole machine by Tox riveting, and the right side wire-passing portion of the right side wire-passing plate 72 may further include second supporting portions 721 arranged on both sides, wherein the second supporting portion 721 close to the rear plate 2 of the whole machine may be connected to the rear plate 2 of the whole machine by Tox riveting, thereby increasing the stability of the air duct structure.

[0064] The above-mentioned implementation makes the air inlet chamber and the lead chamber two separate entities. This divided chamber structure separates the electrical circuit from the oil fume exhaust path, thereby achieving the purpose of oil and electricity separation, avoiding contact with the electrical circuit, protecting the circuit, and at the same time reducing the risk of leakage and improving safety performance.

[0065] See also Figure 4 , which shows a schematic diagram of the distribution of Tox riveting points on the rear plate 2 of the whole machine, where the points indicated by arrows are examples of Tox riveting points. In a specific implementation, the air duct enclosure 1 and the rear plate 2 of the whole machine are respectively formed by molds based on galvanized sheets, and then the air duct enclosure 1, the air duct side panels 4 (including the left side panel 41 of the air duct and the right side panel 42 of the air duct), the left side wire plate 71 and the right side wire plate 72 are placed on the Tox riveting special tooling equipment, and the rear plate 2 of the whole machine is placed on the air duct enclosure 1, the air duct side panels 4 (including the left side panel 41 of the air duct and the right side panel 42 of the air duct), the left side wire plate 71 and the right side wire plate 72, and the Tox riveting special tooling equipment is used based on Figure 4 The distribution of Tox riveting points shown in the figure makes the rear panel 2 of the whole machine fully fit with the air duct enclosure 1, the air duct side panel 4 (including the air duct left side panel 41 and the air duct right side panel 42), the left side wire plate 71 and the right side wire plate 72, thereby realizing the Tox riveting connection.

[0066] In some exemplary embodiments, in order to further improve the sealing performance of the air duct structure, a sealant is provided at the Tox riveted connection of the air duct structure. For example, the sealant may be glass glue.

[0067] In some exemplary embodiments, see Figure 1 The right and / or left enclosing plates of the air duct enclosing plate 1 are provided with openings that match the air outlet of the volute assembly 3, and the air outlet of the volute assembly 3 is connected to the exhaust assembly of the integrated stove through the above openings. In a specific implementation, the exhaust assembly of the integrated stove is horizontally arranged and connected to the above openings on the right and / or left enclosing plates, and the air outlet of the volute assembly 3 is horizontally oriented, so that the exhaust is smoother and the exhaust volume is increased.

[0068] In some exemplary embodiments, see Figure 1 and Figure 2 The air duct structure may further include a volute support strip 8, a volute adapter 9, and a head fixing bracket 10. The volute support strip 8 is respectively connected to the whole machine rear plate 2, the air duct enclosure 2, and the air duct front plate 5 by riveting, so as to provide support force to the volute assembly 3. For example, the volute support strip 8 may be connected to the volute assembly 3 by screws.

[0069] The volute adapter 9 is arranged in the accommodating space of the volute assembly 3, one end of which can be connected to the opening of the duct enclosure 1 and the air outlet of the volute assembly 3 by screws, and the other end of which is connected to the air outlet of the volute assembly 3.

[0070] The head fixing bracket 10 is respectively connected to the rear plate 2 of the whole machine, the left side plate 41 of the air duct, and the right side plate 42 of the air duct by riveting.

[0071] Exemplarily, an electrical box assembly 11 may be further included. The electrical box assembly 11 is disposed on the transverse cover portion 61 of the air duct cover 6 and may be specifically connected to the transverse cover portion 61 by screws.

[0072] Compared with the process of cold-rolled plate forming-spot welding (welding)-spraying treatment used in the prior art, the air duct structure is large in size, and the operator cannot operate alone during spot welding. Two people are required to cooperate to complete it, resulting in high cost of the air duct structure. Moreover, surface spraying involves secondary turnover. Due to the large volume of the air duct component, the turnover is inconvenient and the efficiency is low. It is easy to cause secondary collisions to the product during the turnover process, reducing the yield rate. The surface spraying requires bottom layer pre-treatment (degreasing, pickling, neutralization, washing, phosphating, surface adjustment, drying), and surface spray curing treatment process, which is easy to cause environmental pollution and does not comply with relevant industrial policies. The embodiment of the present application adopts galvanized sheet glue bonding and Tox riveting, which not only ensures the sealing of the air duct structure, but also removes the surface spraying process, so that the air duct structure of the embodiment of the present application does not need secondary turnover, which not only saves the spraying cost, reduces the investment cost of the air duct structure, but also improves the production efficiency, and makes the rear plate of the air duct structure can be shared with the rear plate of the whole machine, further reducing the cost of the air duct structure in the integrated stove.

[0073] The embodiment of the present application also provides an integrated stove, which includes the above-mentioned air duct structure of the embodiment of the present application, greatly reducing the cost of the integrated stove and simplifying the overall structure of the integrated stove.

[0074] The above description is only an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
