[0049] The specific implementation of the embodiment of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the present invention, and is not used to limit the embodiment of the present invention.

[0050] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0051] In the embodiments of the present invention, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used to describe the relative positional relationship of components with respect to the directions shown in the drawings or in the vertical, perpendicular or gravity directions.

[0052] The present invention will be described in detail below in conjunction with exemplary embodiments with reference to the accompanying drawings.

[0053] like Figures 1 to 3As shown, an exemplary embodiment of the present invention provides an integrated stove 100, which includes a body 1, a head 2 and a booster fan 22. The body 1 is provided with a stove top 11, a body flue 12 located below the stove top 11, and a main fan 13 located in the body flue 12. When smoking and exhausting smoke, the main fan 13 must operate to generate wind force for smoking and exhausting smoke. The head 2 is located above the stove top 11 and is provided with a head flue 21 connected to the body flue 12, so that oil smoke can pass through the flue inlet of the head flue 21, the head flue 21 and the body flue 12 in sequence. Usually, the peripheral wall of the body 1 is also provided with a body air outlet 14 connected to the body flue 12, and the oil smoke in the body flue 12 can eventually be discharged from the body air outlet 14. In addition, the booster fan 22 can be set as a cross-flow fan and used to increase the negative air pressure at the flue inlet of the machine head flue 21 to increase the oil fume flow in the machine head flue 21. However, when the main fan 13 is sufficient to form a strong negative air pressure at the flue inlet, the booster fan 22 can be set to a shutdown state.

[0054] It should be noted that since the flue inlet of the machine head flue 21 is usually provided with a flue inlet filter, a certain flow resistance will be formed for the oil smoke. For existing integrated stoves, when the wind force of the main fan 13 is large or the flow resistance caused by the flue inlet filter is small, most of them can guarantee good smoking performance and efficiency. However, when the wind force generated by the main fan 13 is small or the flow resistance caused by the flue inlet filter is large, it is impossible to guarantee the amount of oil smoke that breaks through the flue inlet filter and enters the machine head flue 21, thereby causing the oil smoke to spread in the external environment. Therefore, in this case, the smoking performance and efficiency of the existing integrated stoves are greatly reduced, and since reliability cannot be guaranteed, the user experience will be poor.

[0055] The present exemplary embodiment arranges a booster fan 22 in the integrated stove 100. Even when the wind force generated by the main fan 13 is relatively small or the flow resistance caused by the flue inlet filter is relatively large, it is still possible to ensure that a strong negative air pressure is formed at the flue inlet, thereby ensuring that the oil smoke can break through the flue inlet filter and enter the head flue 21, thereby improving the smoke extraction capacity and efficiency of the integrated stove 100 and further enhancing the user experience.

[0056] In one embodiment, the inlet area of ​​the flue inlet is adjustable, and can preferably be set to be adjusted according to the amount of oil smoke, that is, when the amount of oil smoke increases, the inlet area is expanded, and when the amount of oil smoke decreases, the inlet area is reduced.

[0057] For example, referring to the diagram, the flue inlet may include a main inlet area and a secondary inlet area, the secondary inlet area can be opened or closed, and the booster fan 22 is arranged behind the secondary inlet area. At this time, the integrated stove 100 can switch between the normal smoking state and the strong smoking state. In the normal smoking state, the main fan 13 is turned on to generate wind force for smoking and exhausting smoke, but the booster fan 22 is stopped and the secondary inlet area is closed, and the oil smoke only flows from the main inlet area into the head flue 21. In the strong smoking state, the booster fan 22 and the main fan 13 are turned on at the same time, and the main inlet area and the secondary inlet area are opened at the same time, so as to form a stronger negative air pressure at the flue inlet, and make the flue inlet have a larger inlet area, so that the oil smoke flow in the head flue 21 is greatly increased, and the smoking performance and efficiency of the integrated stove 100 are significantly improved.

[0058] In one embodiment, the machine head 2 also includes a smoke baffle 23, which together with the peripheral wall of the machine head 2 defines a machine head smoke duct 21. At this time, the secondary entrance area, the main entrance area and the smoke baffle 23 are all located on the front side of the machine head smoke duct 21 and can be arranged in sequence from top to bottom.

[0059] Furthermore, the machine head 2 further includes an opening and closing plate 25 and a main inlet oil filter 24 as the aforementioned flue inlet filter, wherein the main inlet oil filter 24 is arranged in the main inlet area, and the opening and closing plate 25 is arranged to open or close the secondary inlet area. Of course, in order to ensure the oil fume filtering effect at the upstream end of the machine head flue 21, a secondary inlet oil filter may also be arranged in the secondary inlet area, and when the opening and closing plate 25 closes the secondary inlet area, the secondary inlet oil filter may be covered by the opening and closing plate 25.

[0060] Generally, the main inlet oil filter 24 is arranged to extend obliquely upward relative to the smoke baffle 23. When the secondary inlet area is arranged adjacent to the main inlet area and located above the main inlet area, the main inlet oil filter 24 and the opening and closing plate 25 can be arranged to extend obliquely upward relative to the smoke baffle 23. At this time, the opening and closing plate 25 can be preferably arranged to be able to be flipped upward. Under this structure, the opening and closing plate 25 can play a role in preventing the oil smoke from climbing up. When the oil smoke is blocked by the opening and closing plate 25, the oil smoke can be quickly sucked into the head flue 21 because the flue inlet has a strong negative pressure.

[0061] In one embodiment, referring to Figures 4 to 6 The booster fan 22 includes a fan bracket 221, a cylindrical fan impeller 222, and an impeller drive motor 223 for driving the fan impeller 222 to rotate. In order to reduce the difficulty of assembling and installing the booster fan 22, the fan impeller 222 and the impeller drive motor 223 can be installed on the fan bracket 221, that is, the booster fan 22 is formed into a component structure. In this way, the booster fan 22 can be assembled outside the integrated stove 100 first, and then the assembled booster fan 22 can be installed in the integrated stove 100 as a whole, which is conducive to improving production efficiency.

[0062] In one embodiment, referring to Figure 7 and Figure 8 , a filtering structure may be provided in the booster fan 22 to enable it to have the function of separating oil smoke. For example, the booster fan 22 may include a cylindrical rotating oil filter 224 for separating oil smoke, and the peripheral wall of the rotating oil filter 224 is provided with a plurality of smoke holes, and the rotating oil filter 224 and the fan impeller 222 are mutually sleeved, for example, the rotating oil filter 224 may be sleeved inside the fan impeller 222, or the fan impeller 222 may be sleeved inside the rotating oil filter 224. Under this structure, when the oil smoke passes through the booster fan 22, it will inevitably pass through the rotating oil filter 224. Since the rotating oil filter 224 is formed as a filter mesh structure, a large number of oil molecules in the oil smoke can be quickly condensed into liquid oil and attached to the rotating oil filter 224 after contacting the rotating oil filter 224, and the filtered oil smoke can flow out through the plurality of smoke holes, thereby realizing oil smoke separation again at the upstream end of the head flue 21.

[0063] Furthermore, the booster fan 22 may also include an oil filter drive motor for driving the rotating oil filter 224 to rotate. By providing the oil filter drive motor, the rotation speed of the rotating oil filter 224 can be accurately controlled, which is more conducive to the rotating oil filter 224 to achieve a better oil fume separation effect while forming a smaller wind resistance. Of course, in some other embodiments, it is not necessary to provide an oil filter drive motor, because the wind field in the head flue 21 can also drive the rotating oil filter 224 to rotate.

[0064] In one embodiment, referring to Figure 4 Only a single booster fan 22 may be provided in the integrated stove 100. Considering the usual size of the flue inlet, in order to ensure that a strong negative pressure can be formed in each area of ​​the flue inlet, the booster fan 22 should be of a longer size.

[0065] In one embodiment, the booster fan 22 may include a first booster fan and a second booster fan that are independently arranged. Figure 5 , the first booster fan and the second booster fan can be arranged to be arranged in a horizontal direction, or refer to Figure 6 , the first booster fan and the second booster fan can also be arranged to be tilted relative to the horizontal plane. Under this structure, the opening and closing, speed, etc. of the first booster fan and the second booster fan are independent of each other, so different types of negative pressure fields can be formed near the flue entrance, and targeted adjustments can be made according to the oil smoke conditions in different areas.

[0066] In one embodiment, referring to Fig. 9The integrated stove 100 further includes a pre-filter 26 for separating oil smoke and a head oil collection box 27 for collecting filtered oil in the pre-filter 26, and the pre-filter 26 can be arranged at the downstream end of the booster fan 22 in the head flue 21. The pre-filter 26 can be arranged in a V-shape, the head oil collection box 27 is located at the bottom end of the V-shape of the pre-filter 26, the smoke baffle 23 is provided with an oil collection box avoidance opening that runs through in the front-to-back direction, and the head oil collection box 27 is arranged to be able to pass through the oil collection box avoidance opening and be taken out forward.

[0067] By setting the above structure, due to the oil fume separation function of the pre-filter 26, a large amount of oil fume has been condensed into liquid oil and attached to the pre-filter 26 before flowing to the fuselage flue 12, thereby effectively reducing the degree of contamination of the main fan 13, thereby ensuring its working efficiency and service life. In addition, by arranging the pre-filter 26 in a V-shape, it can be tilted at a certain angle relative to the horizontal plane, so that the filtered oil is always guided to the bottom of the V-shape under the action of its own gravity, and finally flows into the head oil collection box 27, so as to facilitate the centralized cleaning of the filtered oil.

[0068] In one embodiment, the integrated stove 100 includes a first oil filter 261a and a second oil filter 261b, both of which are pre-filters 26 and arranged in a V shape. Of course, in some other embodiments, only a single pre-filter 26 may be provided, and the pre-filter 26 itself is in a V shape.

[0069] In one embodiment, referring to Fig.10 The pre-filter 26 is configured as a single-layer filter plate and includes an oil filter body 262a, a plurality of smoke holes, an oil guide groove 262f, and an oil filter outlet. The plurality of smoke holes are arranged through the oil filter body 262a, and the peripheral wall of each smoke hole is formed with a hole flange 262e. The oil guide groove 262f is formed between the plurality of hole flanges 262e. The oil filter outlet is arranged at the end of the oil filter body 262a (i.e., the V-shaped bottom end) and communicates with the oil guide groove 262f.

[0070] By setting the above structure, when the oil smoke passes through the multiple smoke holes in the pre-filter 26, a large amount of oil smoke condenses into liquid oil when it contacts the oil filter body 262a and adheres to the oil guide groove 262f, thereby achieving oil smoke separation to reduce the pollution of the main fan 13. Furthermore, the filtered oil in the oil guide groove 262f can be further diverted to the oil filter outlet, which is convenient for collection and cleaning, thereby improving the user experience. It can be seen that by setting the pre-filter 26 as the above-mentioned single-layer filter plate, the functions of separating oil smoke and diverting and filtering oil can be achieved, and at the same time, it has a simple structure for easy processing, which is conducive to improving production efficiency and reducing costs.

[0071] In one embodiment, referring to Fig.11 and Fig.12 The pre-filter 26 is configured as a multi-layer filter plate and includes an oil filter body 262a, which includes a bottom filter unit 262b, a top filter unit 262c and a filter unit connector 262d. The top filter unit 262c and the bottom filter unit 262b are in the shape of long plates and are stacked up and down, and the filter unit connector 262d is used to fix the bottom filter unit 262b and the top filter unit 262c. In addition, the bottom filter unit 262b and the top filter unit 262c are respectively provided with a plurality of smoke holes, and the hole peripheral wall of each smoke hole on the bottom filter unit 262b is formed with a hole flange 262e. The bottom filter unit 262b is also provided with an oil guide groove 262f defined by the plurality of hole flanges 262e and an oil filter outlet provided at the end of the bottom filter unit 262b and connected to the oil guide groove 262f.

[0072] As can be seen from the above structure, the top filter unit 262c and the bottom filter unit 262b stacked up and down can play a multiple filtering role on the oil smoke, so most of the oil in the oil smoke can be effectively intercepted, thereby greatly reducing the pollution of the oil smoke to the main fan 13. The intercepted filtered oil can flow to the bottom filter unit 262b, and under the guidance of the oil guide groove 262f, it is guided to the oil outlet of the oil filter element for collection and cleaning, which is conducive to improving the user experience.

[0073] In addition, in order to increase the interception area, the top filter unit 262c can be set as a bending plate, and the number of bending sections of the bending plate can be determined based on comprehensive considerations such as the actual required interception effect, processing difficulty and production cost.

[0074] The optional implementation modes of the embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the embodiments of the present invention are not limited to the specific details in the above implementation modes. Within the technical concept of the embodiments of the present invention, various simple modifications can be made to the technical scheme of the embodiments of the present invention, and these simple modifications all belong to the protection scope of the embodiments of the present invention.

[0075] It should also be noted that the various specific technical features described in the above specific implementation methods can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the embodiments of the present invention will no longer separately describe various possible combinations.

[0076] In addition, various implementations of the embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the embodiments of the present invention, they should also be regarded as the contents disclosed in the embodiments of the present invention.
