[0002] A traditional range hood includes a housing and a fan, and the fan is arranged inside the housing. An air inlet is arranged at the bottom or side of the housing. When the fan is working, negative pressure is generated inside the housing, and the oil smoke is sucked into the housing from the air inlet and finally discharged. For an integrated range hood, the air inlet is close to the fan, so when the range hood is working, the fan will generate a lot of noise. In order to solve this technical problem, a split range hood has been designed. Since the bellows and the smoke collecting box are separately arranged, the fan can be kept away from the user's operating area when cooking, thereby reducing the harm of noise to the user.

[0003] However, the fumes generated by cooking on the stove enter the bellows through the smoke collecting box under the action of the fan. The cold air generated by the fan in the bellows exchanges heat with the high-temperature fumes. The oil formed by the condensation of the fumes will accumulate in the bellows. If the bellows is installed at the ceiling, the user needs to climb up to clean it due to its high position, which makes cleaning difficult. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0045] like Figure 1-Figure 3 As shown, this embodiment provides a smoke and stove integrated machine, including a stove 200 and a split range hood, the split range hood including a smoke collecting box 300 and a bellows arranged above the smoke collecting box 300, the bottom of the smoke collecting box 300 is connected to the stove 200, the stove 200 is installed on the stove, and is used to connect to the gas pipeline to achieve ignition and combustion after gas supply. The smoke collecting box 300 is installed below the cabinet, and a smoke inlet 301 is arranged on the smoke collecting box 300. The bellows and the smoke collecting box 300 are arranged as a split structure, and the bellows is arranged on the top of the cabinet and connected to the smoke collecting box 300 through a smoke collecting pipe 400. The cabinet is usually installed on the wall on one side of the stove, and an avoidance space is arranged between the cabinet and the wall for the smoke collecting pipe 400 to pass through. The bellows is placed on top, and the fan 2 is arranged in the bellows. The fan 2 is far away from the user, which reduces the noise and reduces the harm to the user caused by the noise generated by the fan 2 when working.

[0046] This embodiment also provides a split range hood, which is applied to the above-mentioned integrated range hood and stove. The integrated range hood and stove includes a bellows for the split range hood, which is fixed to the wall on the top of the cabinet through a hanger 100. The hanger 100 includes two L-shaped support frames, which are fixed to the wall at intervals, and the interval distance is equal to the length of the bellows. The bellows for the split range hood can reduce the accumulation of oil in the bellows, reduce the number of times the user climbs up to clean, and reduce the difficulty of cleaning.

[0047] The present embodiment further provides a bellows for a split range hood, the bellows for a split range hood comprising a housing 1 and a fan 2, the bottom of the housing 1 being provided with a bellows air inlet 111 and a guide surface 112, the bottom of the guide surface 112 being provided at the peripheral side of the bellows air inlet 111, and the guide surface 112 being gradually inclined downward from a direction away from the bellows air inlet 111 to a direction close to the bellows air inlet 111. The fan 2 is provided in the housing 1, and the fan 2 comprises a fan exhaust port 31, and the fan exhaust port 31 is provided toward the bellows air inlet 111. The oil smoke enters the bellows from the bellows air inlet 111 and enters the fan 2 through the fan exhaust port 31. The oil smoke condenses when entering the fan 2. The condensed oil drops from the fan exhaust port 31 to the bottom of the housing 1. A part of the oil is directly discharged from the bellows through the bellows air inlet 111, and the other part of the oil drops on the guide surface 112 and flows obliquely downward along the guide surface 112 to the bellows air inlet 111, so as to prevent the oil from accumulating at the bottom of the housing 1 when flowing to the bellows air inlet 111. At the same time, the guide surface 112 can reduce splashing, thereby preventing the oil from splashing to the inner wall of the housing 1. The bellows for the split range hood provided in this embodiment can guide the oil formed by the condensation of the oil smoke in the fan 2 to be discharged from the housing 1, while reducing the splashing of the oil, thereby reducing the probability of the housing 1 being contaminated by the oil, reducing the number of cleaning times of the bellows for the split range hood, and reducing the difficulty of cleaning.

[0048] In one embodiment, an air outlet 101 is provided on each of the two opposite side walls of the box body 1, and one of the two air outlets 101 is connected to the smoke exhaust pipe 500, and the other is closed by the side cover plate 14. By providing two air outlets 101, the air outlet 101 close to the smoke duct can be selected to be connected to the smoke exhaust pipe 500 according to the position of the smoke duct in the kitchen, and the smoke exhaust pipe 500 is then connected to the smoke duct, which has better flexibility. In order to prevent the dust from outside from entering the box body 1, or the oil smoke in the box body 1 from coming out to pollute the walls and cabinets, the other air outlet 101 is closed by the side cover plate 14.

[0049] Specifically, since the air outlet 101 is set as a square opening and the smoke exhaust pipe 500 is a cylindrical pipe, in order to facilitate the connection between the square opening and the circular end of the cylindrical pipe, the air outlet 101 is connected to the smoke exhaust pipe 500 through the air outlet seat 5. The air outlet seat 5 includes a square connection port and a circular connection port, the square connection port is connected to the air outlet 101, and the circular connection port is connected to the smoke exhaust pipe 500.

[0050] In one embodiment, the box body 1 is configured as a vertical through structure. When installing, the axis of the fan 2 is first installed in the box body 1 along the vertical direction. A top cover plate 13 is provided on the top of the box body 1, and the top cover plate 13 is detachably connected to the box body 1. After the fan 2 is installed, the top cover plate 13 is connected to the top of the box body 1. When repairing the fan 2, it is only necessary to remove the top cover plate 13 to repair the fan 2. The top cover plate 13 can be detachably connected to the box body 1 by means of snap connection or screw fixing.

[0051] In one embodiment, a base is provided at the bottom of the box body 1, and the base is detachably connected to the box body 1. The base includes a bottom plate 11 and a connecting frame 12. The connecting frame 12 is arranged in the circumference of the bottom plate 11. When the base is connected to the box body 1, the four side walls of the box body 1 are directly placed in the connecting frame 12, and fit one by one with the four peripheral walls of the connecting frame 12.

[0052] In one embodiment, the bellows air inlet 111 and the guide surface 112 are arranged at intervals along the width direction of the box body 1, and the bellows air inlet 111 is arranged close to the wall. The rear side wall of the box body 1 is in contact with the wall, the bellows air inlet 111 is arranged close to the wall, the bellows air inlet 111 is connected to the smoke collecting pipe 400, and the smoke collecting pipe 400 is located in the avoidance space between the cabinet and the wall. Such an arrangement reduces the occupied area of ​​the avoidance space and is more suitable for opening the avoidance space in a thin cabinet.

[0053] In one embodiment, the wind box air inlet 111 is connected to the air inlet seat 4, and the end of the air inlet seat 4 close to the box body 1 is provided with a first connection port 41, and the first connection port 41 is adapted to the wind box air inlet 111, and the end of the air inlet seat 4 away from the box body 1 is provided with a second connection port 42, and the second connection port 42 is connected to the smoke collecting pipe 400. Since the wind box air inlet 111 is a square port, and the smoke collecting pipe 400 is a cylindrical pipe, by providing the air inlet seat 4, the first connection port 41 is set as a square port, and the second connection port 42 is set as a circular port, the openings of the wind box air inlet 111 and the smoke collecting pipe 400 of different shapes are connected.

[0054] In one embodiment, the bottom plate 11 includes a guide plate and a horizontal plate, the air box air inlet 111 is arranged on the horizontal plate, the guide plate gradually tilts downward from away from the horizontal plate to close to the horizontal plate, and the inner surface of the guide plate forms a guide surface 112. Such an arrangement makes the air box air inlet 111 closer to the wall, and thus the avoidance space arranged on the cabinet is smaller, so as to be suitable for installing a split range hood in cooperation with a thin cabinet.

[0055] Of course, in other embodiments, a horizontal plate may be set in the center of the bottom plate 11, and guide plates may be set around the horizontal plate. The bellows air inlet 111 may be set on the horizontal plate located in the center of the bottom plate 11. The oil falling from the fan exhaust port 31 may be guided from the guide plates around it to the bellows air inlet 111 and discharged from the box body 1.

[0056] In one embodiment, if Figure 4 As shown, the area of ​​the fan air outlet 31 is larger than the area of ​​the bellows air inlet 111, and the projection of the fan air outlet 31 on the bottom of the housing 1 covers at least a portion of the bellows air inlet 111 and at least a portion of the guide surface 112. The fan air outlet 31 should cover at least a portion of the bellows air inlet 111 and at least a portion of the guide surface 112, so that the oil smoke can enter the housing 1 through the bellows air inlet 111, and the oil liquid condensed in the housing 1, especially at the fan air outlet 31, can flow to the bellows air inlet 111 through the guidance of the guide surface 112, thereby reducing the oil liquid splashing onto the inner wall of the housing 1.

[0057] In one embodiment, a partition plate 3 is further provided in the housing 1, the partition plate 3 is provided at the bottom of the fan 2, and the partition plate 3 is connected to the inner wall of the housing 1 on all sides, and the fan exhaust port 31 is provided on the partition plate 3. With such a configuration, the oil liquid formed after the oil smoke entering the housing 1 condenses at the fan exhaust port 31 will only fall or splash in the space below the partition plate 3, reducing the probability of the space above the partition plate 3 in the housing 1 being contaminated by the oil liquid, and further reducing the difficulty of cleaning the bellows for the split-type range hood.

[0058] The stove and hood integration machine provided in this embodiment adopts the above-mentioned split range hood. The split range hood uses the above-mentioned bellows for the split range hood. The bellows of the split range hood is installed on the top of the cabinet and installed on the wall through the bracket 100, which is far away from the user, not only reducing noise but also reducing the difficulty of cleaning the split range hood.

[0059] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The specific contents of the above specific implementations only express several implementations of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
