[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

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0046] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0047] like Figure 1 and Figure 2 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, the bellows and the smoke collecting box 300 are arranged as a split structure, the smoke collecting box 300 is provided with a smoke inlet 301, the bellows is arranged on the top of the cabinet, and is 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 when the fan 2 is working.

[0048] This embodiment also provides a split range hood, which is applied to the above-mentioned integrated range hood and stove. The bellows of the split range hood 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.

[0049] The present embodiment also provides a bellows for a split-type range hood, comprising a housing 1, a fan 2 and an air guide hood 3. The housing 1 is configured as an upper open structure, so that the fan 2 can be placed in the housing 1 during installation. The housing 1 also includes a cover plate 12, which is disposed on the top of the housing 1 and is detachably connected to the housing 1. After the fan 2 is installed, the upper opening is closed by the cover plate 12 to prevent dust from falling onto the fan 2 and to prevent the oil smoke in the bellows from flowing out of the housing 1 to pollute the walls and ceiling. When the fan 2 is to be repaired, the cover plate 12 can be removed and the fan 2 can be taken out of the housing 1 for repair. The cover plate 12 and the housing 1 can be connected by means of snap connection or screw connection.

[0050] A bellows air inlet is provided at the bottom of the housing 1 , and the bellows air inlet is connected to the smoke collecting box 300 through the smoke collecting pipe 400 . Under the action of the fan 2 , the oil smoke entering the smoke collecting box 300 enters the housing 1 through the smoke collecting pipe 400 and the bellows air inlet.

[0051] The fan 2 includes a fan air outlet 241, and the fan air outlet 241 is arranged toward the air inlet of the bellows. The axis of the fan 2 is a vertical axis, and the fan air outlet 241 is located at the bottom of the fan 2. Under the action of the fan 2, the oil smoke enters the bellows through the air inlet of the bellows. Specifically, the fan 2 includes a motor 22, a wind wheel 23, a volute 21 and an air inlet ring 24. The motor 22 is arranged in the wind wheel 23, the volute 21 is covered on the outer periphery of the wind wheel 23, the air inlet ring 24 is arranged at the bottom of the fan 2, and is connected to the bottom of the volute 21, and the fan air outlet 241 is arranged on the air inlet ring 24.

[0052] In one embodiment, the side wall of the box body 1 is provided with a bellows air outlet 11, and the bellows air outlet 11 is connected to the exhaust pipe 500 through the air outlet seat 5, so that the exhaust gas in the bellows enters the exhaust pipe 500 through the bellows air outlet 11 and is discharged. The bellows air outlet 11 is set as a square opening, and since the exhaust pipe 500 is cylindrical, the end of the air outlet seat 5 connected to the bellows air outlet 11 is set as a square opening, and the end of the air outlet seat 5 connected to the exhaust pipe 500 is set as a circular opening.

[0053] like Figure 3-Figure 5As shown, the air guide hood 3 is arranged between the fan air outlet 241 and the bellows air inlet, and the diameter of the air guide hood 3 gradually shrinks from the fan air outlet 241 to the bellows air inlet. The inner wall of the air guide hood 3 forms a guide surface, and the oil condensed at the fan air outlet 241 is guided to the bellows air inlet along the guide surface. The oil smoke enters the bellows from the air inlet of the bellows, and enters the fan 2 along the air guide cover 3 through the fan exhaust port 241. The oil smoke will not contact the inner wall of the box body 1; moreover, the oil smoke condenses when entering the fan 2, and the diameter of the air guide cover 3 gradually shrinks from the fan exhaust port 241 toward the direction of the bellows air inlet, so that the oil formed by the condensation flows from the fan exhaust port 241 along the guide surface that is inclined downward and has a gradually shrinking diameter to the bellows air inlet. The oil will not accumulate and splash around in the process of flowing to the bellows air inlet, thereby reducing the accumulation of oil in the fan 2 and the box body 1. Therefore, there is no need to clean the bellows frequently, which reduces the difficulty of cleaning the bellows.

[0054] In one embodiment, the air inlet of the bellows is provided with an air inlet seat 4, the air inlet seat 4 includes an air inlet tube 41 and an air inlet tube end face 42, a support base plate 31 is provided at one end of the air guide cover 3 close to the air inlet seat 4, a plug-in tube 32 extending toward the air inlet seat 4 is provided at the center of the support base plate 31, the plug-in tube 32 is inserted into the air inlet tube 41, and the support base plate 31 is supported on the air inlet tube end face 42. In order to ensure the stability of the connection of the air guide cover 3, the end of the air guide cover 3 close to the air inlet of the bellows is connected to the air inlet seat 4, the air inlet tube end face 42 of the air inlet seat 4 is fitted with one side of the circumference of the air inlet of the bellows, and the support base plate 31 is fitted with the other side of the circumference of the air inlet of the bellows, and the plug-in tube 32 is inserted into the air inlet tube 41 through the air inlet of the bellows, and then the support base plate 31 and the air inlet tube end face 42 are fixed to the circumference of the air inlet of the bellows by screwing or welding, so that the air inlet seat 4 and the air guide cover 3 are connected to the bottom of the box body 1.

[0055] In one embodiment, a connecting outer edge 33 is provided at one end of the air guide cover 3 close to the fan air outlet 241, and the connecting outer edge 33 is connected to the fan 2. The top of the air guide cover 3 is connected to the fan 2 through the connecting outer edge 33, so that the fan air outlet 241 is connected to the air guide cover 3. Specifically, the connecting outer edge 33 is connected to the air inlet ring 24. The connecting outer edge 33 and the air inlet ring 24 can be detachably connected by means of screw connection or abutment.

[0056] In one embodiment, the air guide cover 3 is configured to be in a conical barrel shape or a trumpet shape. The inner wall of the conical barrel-shaped air guide cover 3 forms a flow guide surface, and similarly, the inner wall of the trumpet-shaped air guide cover 3 forms a flow guide surface.

[0057] Of course, in other embodiments, the air guide cover 3 may also be configured as a hexagonal body with a gradually shrinking caliber.

[0058] In order to save space in the kitchen, the distance between the front side of the cabinet and the wall is limited, so the setting position of the bellows air inlet is restricted, resulting in a small distance between the bellows air inlet and the wall. The guide surface of the air guide cover 3 on the side close to the wall has insufficient inclination space and cannot be consistent with the inclination angle of the guide surface on the side away from the wall. If the inclination angles of the guide surfaces on both sides are too small, the oil diversion effect will be affected.

[0059] In order to solve the above technical problems, in one embodiment, Figure 6 As shown, the guide surface includes an inclined guide surface 34 and a vertical guide surface 35. The inclined guide surface 34 is arranged on the side of the air guide cover 3 away from the wall, and the vertical guide surface 35 is arranged on the side of the air guide cover 3 close to the wall. Exemplarily, the side of the conical barrel-shaped air guide cover 3 close to the wall is set as a vertical plane, so that the guide surfaces formed by the inner wall of the conical barrel-shaped air guide cover 3 except the vertical plane are all inclined guide surfaces 34 inclined inward from top to bottom, and the guide surface formed by the inner wall of the vertical plane is the vertical guide surface 35.

[0060] The stove and hood integration machine provided in this embodiment adopts the above-mentioned split range hood. The split range hood uses a bellows for the split range hood. The bellows of the split range hood is installed on the top of the cabinet and is installed on the wall through a bracket 100, which is far away from the user, not only reducing noise but also reducing the difficulty of cleaning the split range hood.

[0061] 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.

[0062] 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.
