Description

Technical Field

[0001] The present invention relates to the technical field of integrated stoves, and in particular to an integrated stove. Background Art

[0002] Relevant technologies point out that existing integrated stoves are mainly composed of a head part, a stove system, a body, a fan system and additional assemblies (steamer, oven or disinfection cabinet, etc.), among which the fan system in the integrated stove is mainly responsible for removing oil smoke and providing users with a fresh and hygienic kitchen environment.

[0003] At present, the fans of integrated stoves are mostly placed vertically in the air duct below the head, with the fan rotation axis horizontal and the air inlet facing the back of the integrated stove (reference Figure 7 ). The main problems of this solution are insufficient utilization of the body structure space and poor exhaust of oil smoke. In terms of structural space utilization: the fan is placed vertically on the back of the integrated stove. The thickness of the fan itself and the gap that must be left for the fan air inlet will occupy more than 1 / 3 of the depth of the integrated stove body. This will cause the width of the steaming and baking trays that can be placed in the additional assemblies of the integrated stove, such as the steamer and oven, to be smaller, and the number of dishes that can be placed at one time will be reduced, which will bring inconvenience to customers; in terms of poor exhaust of oil smoke: after the oil smoke passes through the fan, it vertically enters the horizontally placed smoke pipe, and then enters the public smoke duct after a 90° turn. In this structure, the wind resistance between the fan outlet and the public pipe is large, which is not conducive to smoke exhaust;

[0004] In addition, there are also integrated stove fans placed horizontally in the air duct, with the fan rotation axis perpendicular to the horizontal plane and the fan air inlet parallel to the horizontal plane (reference Figure 6 ). This solution can solve the problems in the above fan layout solution, but for a horizontally placed fan, the fan air inlet and the air duct shell form a narrow space, and the air with oil smoke needs to turn 90 degrees twice in a row before it can enter the fan vertically, which will increase the wind resistance between the fan air inlet and the air duct inside the head, and reduce the smoke exhaust efficiency. At the same time, this structure will also cause turbulence in the flow field near the air inlet, increasing the aerodynamic noise of the fan. Summary of the invention

[0029] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0030] Reference below Figures 1 to 7 An integrated cooker 100 according to the present invention is described.

[0031] As shown in FIG. 2 , the integrated stove 100 according to the present invention includes: a stove body 1 and a smoke exhaust fan 2 .

[0032] Specifically, a smoke exhaust duct 10 is formed in the stove body 1, and the smoke exhaust duct 10 includes: a first duct 111 and a second duct 121, wherein the first duct 111 extends in a vertical direction, and the first vertical duct is located at the rear of the stove body 1; one end of the second duct 121 (for example Figure 1 The rear end of the second air duct 121 shown in FIG. 1 is connected to the lower end of the first air duct 111, and the other end of the second air duct 121 (for example Figure 1 The front end of the second air duct 121 shown in the figure generally extends in the horizontal direction; the smoke exhaust fan 2 is arranged in the second air duct 121 and adjacent to the first air duct 111, and the smoke exhaust fan 2 has an air inlet 211, which is arranged toward the lower end of the first air duct 111.

[0033] In this way, the first air duct 111 and the second air duct 121 are constructed to be approximately perpendicular to each other, and the air inlet 211 of the smoke exhaust fan 2 is inclined relative to the horizontal direction. Compared with the vertically upward arrangement of the smoke exhaust fan air inlet in the related art, the angle of the corner through which the oil smoke passes in the process of flowing from the first air duct 111 to the smoke exhaust fan 2 is changed, thereby reducing the wind resistance. At the same time, compared with the horizontal arrangement of the air inlet of the smoke exhaust fan toward the rear side wall of the smoke exhaust duct in the related art, since the smoke exhaust fan 2 is arranged in the second air duct 121 in this embodiment, the first air duct 111 can reduce its width along the front-to-back direction without affecting the air intake efficiency, thereby saving the internal space occupied by the stove body 1 and optimizing the internal layout of the stove body 1.

[0034] According to the integrated stove 100 of the present invention, by constructing the first air duct 111 and the second air duct 121 of the smoke exhaust duct 10 to be substantially vertical, and obliquely arranging the smoke exhaust fan 2 in the second air duct 121, the wind resistance of the smoke exhaust duct 10 can be reduced and the smoke exhaust efficiency can be improved by changing the angle of the corner through which the smoke enters the smoke exhaust fan 2 from the first air duct 111, and the internal space of the stove body 1 occupied by the smoke exhaust duct 10 can be saved, thereby facilitating the optimization of the internal layout of the stove body 1.

[0035] According to some embodiments of the present invention, the smoke exhaust fan 2 is a horizontal fan, and in the direction from bottom to top, the rotation axis of the smoke exhaust fan 2 extends backward and obliquely toward the lower end of the first air duct 111, and the air inlet 211 is perpendicular to the rotation axis of the smoke exhaust fan 2. Thus, the smoke exhaust fan 2 is tilted in the second air duct 121, so that the smoke exhaust duct 10 can reduce wind resistance and improve smoke exhaust efficiency by changing the angle of the corner through which the smoke passes when entering the smoke exhaust fan 2 from the first air duct 111.

[0036] According to some embodiments of the present invention, reference Figures 3 to 5 The stove body 1 may include: a first air duct enclosure 11 and a second air duct enclosure 12. Specifically, the first air duct enclosure 11 is in a cylindrical shape extending in the up-down direction and open at both ends, and the inner side of the first air duct enclosure 11 defines a first air duct 111; the second air duct enclosure 12 extends in the horizontal direction, and the inner side of the second air duct enclosure 12 defines a second air duct 121, and the rear end of the second air duct enclosure 12 is connected and communicated with the lower end of the first air duct enclosure 11, thereby simplifying the structure of the smoke exhaust air duct 10.

[0037] Further, refer to Figures 3 to 5 , the second air duct enclosure 12 may include: a bottom plate 123 and a top plate 122. Specifically, the bottom plate 123 and the top plate 122 are arranged at intervals in the up-down direction, the bottom plate 123 extends upwardly at an angle from the back to the front, and the smoke exhaust fan 2 is fixed on the bottom plate 123, wherein the rotation axis of the smoke exhaust fan 2 is arranged perpendicular to the bottom plate 123, and the air inlet 211 is formed on the upper side surface of the smoke exhaust fan 2 in the axial direction, so that the smoke exhaust fan 2 can be easily fixed, and the air inlet 211 of the smoke exhaust fan 2 is inclined toward the lower end of the first air duct 111, which is also convenient for the oil to flow out of the air duct faster under the action of gravity.

[0038] Furthermore, refer to Figure 2The smoke exhaust fan 2 includes: a volute 21 and a wind wheel 22, wherein the wind wheel 22 is arranged in the volute 21, and the air inlet 211 is formed on the volute 21. The distance between the center point of the air inlet 211 and the top plate 122 is at least 1 / 4 times the thickness of the volute 21 in the axial direction of the smoke exhaust fan 2. For example, the distance between the center point of the air inlet 211 and the top plate 122 can be 1 / 4 times, 1 / 2 times or 3 / 4 times the thickness of the volute 21 in the axial direction of the smoke exhaust fan 2. In this way, it is convenient for smoke to enter the smoke exhaust fan 2 more smoothly from the connection between the first air duct 111 and the second air duct 121. Preferably, the distance between the center point of the air inlet 211 and the top plate 122 is about 1 / 3 times the thickness of the volute 21 in the axial direction of the smoke exhaust fan 2.

[0039] According to some embodiments of the present invention, reference Figure 4 The top plate 122 is a horizontal plate extending in the horizontal direction, and the rear end of the top plate 122 is connected to the front side plate 112 of the first air duct enclosure 11 in an arc, which can avoid the problem of increased wind resistance caused by the right-angle connection.

[0040] Further, the arc radius between the rear end of the top plate 122 and the front side plate 112 of the first air duct enclosure 11 is at least 0.8 times the thickness of the first air duct enclosure 11 in the front-to-back direction. For example, the arc radius between the rear end of the top plate 122 and the front side plate 112 of the first air duct enclosure 11 may be 0.8 times, 0.9 times or 1.1 times the thickness of the first air duct enclosure 11 in the front-to-back direction, thereby further reducing the resistance at the corner of the first air duct 111 and the second air duct 121. Preferably, the arc radius between the rear end of the top plate 122 and the front side plate 112 of the first air duct enclosure 11 may be approximately equal to the thickness of the first air duct enclosure 11 in the front-to-back direction.

[0041] According to some embodiments of the present invention, a noise reduction layer is provided on the lower surface of at least the portion of the top plate 122 opposite to the smoke exhaust fan 2. That is to say, the noise reduction layer may be provided on the inner surface of the portion of the top plate 122 opposite to the smoke exhaust fan 2, or the entire inner surface of the top plate 122 may be covered by the noise reduction layer. Thus, the overall noise level of the integrated stove 100 during operation can be further reduced.

[0042] Of course, the present invention is not limited thereto, and the inner surface of the first air duct 111 may also be provided with a noise reduction layer, so that the overall noise level of the integrated stove 100 can be better controlled.

[0043] In some embodiments, reference Figure 1An oil leakage nozzle (not shown) is provided at the rear end of the bottom plate 123. The integrated stove 100 may further include: an oil collecting box 3, which is provided below the bottom plate 123 and is opposite to the oil leakage nozzle up and down. In this way, the oil absorbed by the smoke exhaust fan 2 can flow into the oil collecting box 3 through the oil leakage nozzle along the inclined bottom plate 123 under the action of gravity.

[0044] According to some embodiments of the present invention, reference Figure 2 The bottom plate 123 is provided with a mounting hole 1231, which penetrates the bottom plate 123 in the thickness direction. The smoke exhaust fan 2 is arranged at the mounting hole 1231 and is sealed and connected to the periphery of the mounting hole 1231, so that the connection between the smoke exhaust fan 2 and the bottom plate 123 can be more stable. Of course, the present invention is not limited to this, and reference Figure 3 A mounting hole 1231 may also be provided on the side wall of the second air duct 121 , the mounting hole 1231 passing through the side wall in the thickness direction, and part of the smoke exhaust fan 2 may be embedded in the mounting hole 1231 , so that the volume of the second air duct 121 may be further reduced, saving the internal space of the stove body 1 .
