Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to an air duct system of a smoking oven. Background Art

[0002] A smoking oven is a household appliance used for smoking and grilling food. Besides having the taste of grilled food, it also has a unique smoked flavor, which is deeply loved by some consumers. The basic structure of the existing smoking ovens on the market generally sets a smoking box inside the oven body. When grilling, a smoking cake is placed in the smoking box, and the high temperature is used to heat the smoking cake to smoke the food. For this kind of smoking oven with this structural form, although the structure of the smoking box is relatively simple and easy to manufacture, in actual application, it is not conducive to operation, and the heat generated during the smoking process will be transferred to the surface of the oven, which is easy to scald and poses a safety hazard. For this reason, some ovens add heat insulation cotton inside, but this increases the structural complexity of the oven and brings inconvenience to production and assembly. Summary of the Invention

[0005] The air duct system of the smoking oven includes a smoking main body and a smoke generator arranged in parallel.

[0006] The smoking main body is provided with a smoking cavity and a first air duct distributed on the periphery of the smoking cavity. The first air duct and the first fan are combined to construct a negative pressure air suction system, so that the first air duct sucks in the outside cold air under negative pressure, exchanges heat and then discharges it, thereby taking away the heat on the periphery of the smoking cavity.

[0007] The smoke generator is provided with an electronic control module and a second air duct for dissipating heat in cooperation with the electronic control module. The second air duct and the second fan are combined to construct a positive pressure air supply system, so that the air blown by the second fan is guided to the electronic control module through the second air duct to realize heat dissipation of the electronic control module. And the electronic control module is inclined and forms an included angle with the axial direction of the air blown by the second fan, so that the electronic control module faces the incoming air in an inclined posture and guides the air flow, increasing the contact surface and residence time, and playing a guiding role in the flow to improve the heat dissipation effect.

[0008] Further, in the above solution, the smoking main body has an inner liner enclosing a smoking cavity and an outer shell wrapping the inner liner. A first air duct is formed by spacing the inner liner and the outer shell apart. The structure is simple, the coverage area of the first air duct is increased, and it is beneficial to take away the heat outside the smoking cavity. The first air inlet of the first air duct is arranged at the lower side of the oven, and the first air outlet of the first air duct is arranged at the rear side of the oven. The first fan is installed at the rear end of the oven and placed in the first air duct.

[0009] Further, in the above solution, the second air inlet of the second air duct is arranged at the rear side of the oven, and the second air outlet of the second air duct is arranged at the front side of the oven. Moreover, the second air outlet is below the electronic control module, so that the air input from the second air inlet is guided by the inclined posture of the electronic control module and moves to the second air outlet.

[0010] Further, in the above solution, the first fan is installed on the upper side of the rear end of the oven, and the air suction port of the first fan is flush with the upper top surface of the inner liner.

[0011] Further, in the above solution, the smoking main body and the smoke generator are connected together by sharing the same back plate and the same bottom plate.

And a first air duct is constructed outside the smoking cavity and a second air duct is constructed on the smoke generator. The first air duct and the first fan are combined to construct a negative pressure air suction system, so that the first air duct sucks in outside cold air under negative pressure, exchanges heat and then discharges it, thereby taking away the heat outside the smoking cavity. The second air duct and the second fan are combined to construct a positive pressure air supply system, so that the air blown out by the second fan is guided to the electronic control module through the second air duct to realize heat dissipation of the electronic control module, thus achieving heat dissipation of the smoking oven, making it safer to use and having better market benefits.

[0020] The following will further illustrate the concept, specific structure and technical effects generated by the utility model in conjunction with the drawings, so as to fully understand the purpose, features and effects of the utility model.

[0021] It should be noted that in the description of the present utility model, the terms indicating directions or positional relationships such as "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings. This is only for the convenience of description, rather than indicating or implying that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0022] Refer to Figures 1 to 7As shown in the figure, it is a schematic diagram of a preferred embodiment of the present utility model. The present utility model relates to an air duct system of a smoking oven. The smoking oven includes a smoking main body 1 and a smoke generator 2 arranged in parallel. In this embodiment, the smoking main body 1 and the smoke generator 2 are connected together by sharing the same back plate 5 and the same bottom plate 6, which is convenient for manufacturing and assembling and also increases the overall structural integrity of the product. The smoking main body 1 is provided with a smoking chamber 11 and a first air duct 12 distributed on the outer periphery of the smoking chamber 11. The smoking chamber 11 is suitable for placing food for smoking. For this purpose, a door 15 is also provided to cooperate with the opening and closing of the smoking chamber 11 for taking and placing food. The first air duct 12 and the first fan 3 are combined to construct a negative pressure air suction system, so that the first air duct 12 sucks in external cold air under negative pressure, exchanges heat and then discharges it, thereby being able to take away the heat outside the smoking chamber and prevent external burns, improving the safety of using the oven. The smoke generator 2 is provided with an electronic control module 21 and a second air duct 22 for dissipating heat in cooperation with the electronic control module 21. The electronic control module 21 includes a corresponding control board and components installed on the control board to achieve electronic control heating, so that the fuel burns to generate the required smoke and is then transported into the smoking chamber for smoking processing. The second air duct 22 and the second fan 4 are combined to construct a positive pressure air supply system, so that the air blown by the second fan 4 is guided to the electronic control module 21 through the second air duct 22 to dissipate heat from the electronic control module, ensuring the normal and safe operation of the electronic control module 21 and extending its service life. At the same time, in this embodiment, the second air duct 22 guides the air linearly to the electronic control module 21, and the electronic control module 21 is inclined and forms an angle with the axial direction of the air blown by the second fan 4, so that the electronic control module faces the incoming air in an inclined posture and guides the air flow, increasing the contact area and residence time, and playing a role in guiding the flow and improving the heat dissipation effect.

[0023] By arranging the smoking main body 1 and the smoke generator 2 in parallel, not only can the smoke be generated from the smoke generator and sent into the smoking chamber of the smoking main body, but also the structure is simple and compact, convenient and practical, conducive to manufacturing, assembling and maintenance, simplifies the structure of the smoking main body, and greatly improves the usability of the oven. And by constructing the first air duct 12 on the outer periphery of the smoking chamber 11 and the second air duct 22 on the smoke generator 2, the first air duct 12 and the first fan 3 are combined to construct a negative pressure air suction system, so that the first air duct sucks in external cold air under negative pressure, exchanges heat and then discharges it, thereby taking away the heat outside the smoking chamber, and the heat is taken away relatively thoroughly, reducing the occurrence of external burns caused by the heat outside the smoking chamber; the second air duct 22 and the second fan 4 are combined to construct a positive pressure air supply system, so that the air blown by the second fan is guided to the electronic control module 21 through the second air duct, realizing heat dissipation of the electronic control module, blowing air forward, enabling the cold air to move to the electronic control module more evenly and without dead angles, improving the heat dissipation effect, being safer to use, and having better market benefits.

[0024] Refer to Figure 2 、 4, as shown in Figures 6 and 7, in this embodiment, the smoking main body 1 has an inner liner 13 enclosing a smoking cavity 11 and an outer shell 14 wrapping the inner liner, which is a double-layer structure. And a first air duct 12 is formed by spacing apart the inner liner 13 and the outer shell 14. In this way, the first air duct 12 can cover the inner liner 13 in a relatively large range, which is beneficial to completely take away the heat outside the periphery of the smoking cavity. The first air inlet 121 of the first air duct 12 is arranged on the lower side of the oven, and the first air outlet 122 of the first air duct 12 is arranged on the rear side of the oven. The first fan 3 is installed at the rear end of the oven and placed in the first air duct 12, with a compact structure. During operation, it sucks air from bottom to top, and at the same time conforms to the heat rising effect, which can help take away the heat. The first fan 3 is preferably a centrifugal fan, and the first fan 3 is installed on the upper side of the rear end of the oven. The air suction port of the first fan 3 is flush with the upper top surface of the inner liner 13. At the same time, the air suction port of the first fan 3 can be elongated in the width direction of the upper top surface of the inner liner 13 to increase the suction effect. The design of the first air duct 12 is simple in structure. It can not only cooperate with the first fan 3 to take away the heat outside the periphery of the smoking cavity and prevent the heat outside the periphery of the smoking cavity from being transferred to the surface of the oven, but also the first air duct 12 can form a heat insulation groove to play a protective role.

[0025] Referring to Figure 2 , 3 , 5, 6, and 7, in this embodiment, the second air inlet 221 of the second air duct 22 is arranged on the rear side of the oven, and the second air outlet 222 of the second air duct 22 is arranged on the front side of the oven, and the second air outlet 222 is below the electronic control module 21; and the electronic control module 21 is inclined, so that the air blown in from the second air inlet 221 is guided by the inclined posture of the electronic control module 21 and moves to the second air outlet 222. This structure not only facilitates the installation and operation of the electronic control module 21, but also can use the inclined posture of the electronic control module 21 to guide the air, so that the directly blowing cold air can be effectively guided to move, increasing the heat dissipation effect, and the flow is natural and smooth, and the wind loss is reduced.

[0026] In this embodiment, the back panel 5 participates in constructing both the first air duct 12 and the second air duct 22, and the bottom panel 6 participates in constructing the first air duct 12, with a simple and compact structure, which is convenient for manufacturing and assembling. The first air duct 12 and the second air duct 22 respectively use different air movement methods to achieve the heat insulation protection of the box body and the heat dissipation of the control parts, which is beneficial to the design, manufacture and use experience of the oven.

[0027] Although the preferred specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention should not be limited to the exact same structure and operation as described above and shown in the drawings. For those skilled in the art of this technology, without departing from the concept and scope of the present invention, many equivalent improvements and changes can still be made to the above embodiments through logical analysis, reasoning or limited experiments, but these improvements and changes should all fall within the scope of protection required by the present invention.
