Detailed ways

The specific implementations of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only used to illustrate and explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention.

It should be noted that the embodiments of the present invention and the features of the embodiments may be combined with each other under the condition of no conflict.

In the embodiments of the present invention, unless otherwise stated, the directional words used such as "upper, lower, top, bottom" are usually for the directions shown in the drawings or for vertical, vertical or A word describing the mutual positional relationship of each component in the direction of gravity.

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

As shown in FIGS. 1 to 3 , an exemplary embodiment of the present invention provides an integrated cooktop 100 . The integrated cooktop 100 includes a body 1 , a handpiece 2 and a booster fan 22 . The body 1 is provided with a cooktop 11, a body flue 12 located below the cooktop 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 smoke Smoke wind. The head 2 is located above the cooktop 11 and is provided with a head flue 21 that communicates with the fuselage flue 12, so the oil fume can pass through the flue inlet of the head duct 21, the head duct 21 and the fuselage flue in sequence. 12. Generally, the peripheral wall of the fuselage 1 is further provided with a fuselage air outlet 14 that communicates with the fuselage flue 12. The oil fume in the fuselage flue 12 can finally be discharged from the fuselage air outlet 14. In addition, the booster fan 22 can be set as a cross-flow fan and is used to increase the negative air pressure at the flue inlet of the nose flue 21, so as to increase the oil fume flow in the nose flue 21, but the main fan 13 is sufficient to When a strong negative air pressure is formed at the entrance of the flue, the booster fan 22 can be set to a shutdown state.

It should be noted that, since the flue inlet of the nose flue 21 is usually provided with a flue inlet filter, a certain flow resistance will be formed on the oil fume. For existing integrated stoves, better smoking performance and efficiency can be ensured in most cases when the wind force of the main fan 13 is relatively large or the flow resistance brought by the flue inlet filter screen is relatively small. However, when the wind force generated by the main fan 13 is small or the flow resistance brought by the flue inlet filter screen is relatively large, the amount of oil fume that breaks through the flue inlet filter screen and enters the machine head flue 21 cannot be guaranteed, thereby causing the oil fume to flow outside. Therefore, in this case, the smoking performance and efficiency of the existing integrated stove are greatly reduced, and since the reliability cannot be guaranteed, the user experience will be deteriorated.

However, in the present exemplary embodiment, by disposing the booster fan 22 in the integrated stove 100, even when the wind force generated by the main fan 13 is small or the flow resistance brought by the flue inlet filter screen is relatively large, the smoke can still be guaranteed. A strong negative air pressure is formed at the entrance of the flue, thereby ensuring that the oil fume can break through the flue entrance filter and enter the machine head flue 21, thereby improving the smoking ability and efficiency of the integrated stove 100, thereby improving the user experience.

In one embodiment, the inlet area of the flue inlet can be adjusted, and can preferably be adjusted according to the amount of oil fume, that is, when the amount of oil fume increases, the inlet area is enlarged, and when the amount of oil fume decreases, the inlet area is reduced.

For example, referring to the drawings, 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 disposed behind the secondary inlet area. At this time, the integrated cooktop 100 can be switched between a normal smoking state and a strong smoking state. In the normal smoking state, the main fan 13 is turned on to generate wind for smoking and exhausting smoke, but the booster fan 22 is stopped and the auxiliary inlet area is closed, and the oil fume only flows into the nose flue 21 from the main inlet area. 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 auxiliary inlet area are turned on at the same time, so that a stronger negative air pressure is formed at the entrance of the flue, and the entrance of the flue has a larger negative pressure. The inlet area is greatly increased, thereby greatly increasing the oil fume flow in the head flue 21, and the smoking performance and efficiency of the integrated stove 100 are significantly improved.

In one embodiment, the nose 2 further includes a smoke baffle 23, which together with the peripheral wall of the nose 2 defines the nose flue 21. At this time, the auxiliary entrance area, the main entrance area and the smoke baffle 23 are all located on the front side of the nose flue 21 and can be arranged in order from top to bottom.

Further, the machine head 2 also includes an opening and closing plate 25 and a main inlet oil filter screen 24 as the aforementioned flue inlet filter screen, wherein the main inlet oil filter screen 24 is arranged in the main inlet area, and the opening and closing plate 25 is arranged for opening or closing. Close the secondary entrance area. Of course, in order to ensure the oil fume filtering effect at the upstream end of the flue duct 21, the auxiliary inlet oil filter can also be set in the auxiliary inlet area. When the opening and closing plate 25 closes the auxiliary inlet area, the auxiliary inlet oil filter can be opened and closed by the opening and closing plate 25. cover.

Generally, the main inlet oil filter 24 is arranged to extend obliquely upward relative to the smoke baffle 23. When the auxiliary inlet area is adjacent to the main inlet area and is located above the main inlet area, the main inlet oil filter 24 and the opening can be separated. The closing plates 25 are all arranged to extend upwardly obliquely relative to the smoke baffle plate 23 , and at this time, the opening and closing plates 25 can preferably be arranged to be able to be turned upward. Under this structure, the opening and closing plate 25 can prevent the oil fume from climbing up. When the oil fume is blocked by the opening and closing plate 25, since the inlet of the flue has a strong negative air pressure, the oil fume can be quickly sucked into the nose flue 21. Inside.

In one embodiment, referring to FIGS. 4 to 6 , the booster fan 22 includes a fan support 221 , a cylindrical fan impeller 222 and an impeller driving motor 223 for driving the fan impeller 222 to rotate. In order to reduce the assembly difficulty and installation difficulty of the booster fan 22 , both 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 as a component structure. In this way, the booster fan 22 can be assembled outside the integrated cooker 100 first, and then the assembled booster fan 22 can be installed in the integrated cooker 100 as a whole, thereby helping to improve production efficiency.

In an embodiment, referring to FIG. 7 and FIG. 8 , a filter structure may be provided in the booster fan 22 so that it has the function of separating oil fume.

Under this structure, when the oil fume passes through the booster fan 22, it will inevitably pass through the rotary oil filter 224. Since the rotary oil filter 224 is formed into a filter screen structure, a large number of oil molecules in the oil fume contact the rotary oil filter 224 after contacting the rotary oil filter 224. It can be quickly condensed into liquid oil and adhered to it, and the filtered oil fume can flow out through a plurality of smoke passing holes, so that the oil fume separation can be realized again at the upstream end of the flue 21 of the machine head.

Further, the booster fan 22 may further include an oil filter element driving motor for driving the rotary oil filter element 224 to rotate. The rotating oil filter element 224 can achieve a better oil fume separation effect while forming a smaller wind resistance. Of course, in some other embodiments, it is also not necessary to provide a driving motor for the oil filter, because the wind field in the flue 21 of the nose can also drive the rotary oil filter 224 to rotate.

In one embodiment, referring to FIG. 4 , only a single booster fan 22 may be provided in the integrated stove 100. Considering the general size of the flue inlet, in order to ensure that a strong force can be formed in each area of the flue inlet Negative air pressure, the booster fan 22 at this time should have a longer size.

In one embodiment, the booster fan 22 may include a first booster fan and a second booster fan that are provided independently of each other, and further, referring to FIG. 5 , the first booster fan and the second booster fan may be Both are arranged to be arranged laterally, or with reference to FIG. 6 , both the first booster fan and the second booster fan may be arranged to be tilted relative to the horizontal plane. Under this structure, the opening and closing, rotational 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 entrance of the flue, which can be targeted according to the fumes in different areas. Sexual regulation.

In one embodiment, referring to FIG. 9 , the integrated stove 100 further includes a pre-filter element 26 disposed in the head flue 21 for separating oil fume and a pre-filter element 26 for collecting the oil in the pre-filter element 26 .

Among them, the front oil filter 26 can be arranged in a V-shaped arrangement, the oil collecting box 27 of the machine head is located at the bottom end of the V shape of the front oil filter 26, and the smoke baffle 23 is provided with an oil collecting box that runs through the front and rear directions. For the avoidance port, the oil collecting box 27 of the machine head is set so that it can be taken out forward through the avoidance port of the oil collecting box.

By arranging the above structure, due to the oil fume separation effect of the pre-oil filter 26, a large amount of oil fume is condensed into liquid oil before flowing to the fuselage flue 12 and adheres to the pre-oil filter 26, thereby effectively reducing the main fan. 13 degree of contamination, thereby ensuring its work efficiency and service life. In addition, by arranging the pre-filter element 26 in a V-shape, it can be inclined at a certain angle relative to the horizontal plane, so that the filter oil is always guided to the bottom end of the V-shape under the action of its own gravity, and finally flows into In the oil collecting box 27 of the machine head, it is convenient for centralized cleaning of the oil filter.

In one embodiment, the integrated cooktop 100 includes a first oil filter member 261a and a second oil filter member 261b. The first oil filter member 261a and the second oil filter member 261b are both the pre-oil filter member 26 and have a V shape. shape arrangement. Of course, in some other embodiments, only a single pre-filter element 26 may be provided, and in this case, the pre-filter element 26 itself is V-shaped.
