[ detailed description ] embodiments
To make the objects, solutions and advantages of the present application more clear, the present application is further described below with reference to the accompanying drawings and preferred embodiments.
The single-side air inlet lampblack exhaust fan provided by the application comprises a volute, an impeller 5, a motor 4 suitable for driving the impeller 5, a motor support 9 and a motor cover 8, and is suitable for exhausting lampblack in a kitchen as shown in fig. 2. The single-side air inlet fume exhaust fan is a centrifugal fan. The impeller 5 is arranged in the cavity of the volute, and the impeller 5 is a multi-wing centrifugal impeller 5. The motor bracket 9 is used for fixing the motor 4. The volute is provided with an air inlet 6 and an air outlet 7.
The volute comprises a first side plate 1, a second side plate 2 and a surrounding plate 3, wherein the surrounding plate 3 is arranged between the first side plate 1 and the second side plate 2, as shown in fig. 2. The first side plate 1, the second side plate 2 and the enclosing plate 3 jointly enclose an air outlet 7. The periphery of the air outlet 7 is provided with a fixed frame 10, and the fixed frame 10 is provided with screw holes for fixing the volute.
The air inlet 6 is arranged on the first side plate 1. It should be noted that, since the embodiment of the range hood fan is a single-side intake range hood fan, the air inlet 6 of the first side plate 1 is the only air inlet of the embodiment of the range hood fan.
The motor cover 8 protrudes outward from the second side plate 2, as shown in fig. 2, the motor cover 8 and the second side plate 2 are integrated, and specifically, the motor cover 8 and the second side plate 2 are formed by stamping the same metal plate. The motor cover 8 is groove-shaped, and the edge of the opening of the groove is connected with the second side plate 2. The inner wall of the groove of the motor cover 8 is in a circular truncated cone shape, and the side wall of the circular truncated cone gradually gathers in the direction away from the second side plate 2, as shown in fig. 2. The inner wall of the groove of the motor cover 8 is of a non-porous structure, and airflow in a containing cavity (the containing cavity is an inwards concave cavity of the groove structure) of the motor cover 8 cannot penetrate through the wall body of the motor cover 8.
The motor 4 is partially arranged in the accommodating cavity of the motor cover 8, and an air flow channel is formed between the inner wall of the accommodating cavity of the motor cover 8 (the inner wall of the accommodating cavity, namely the inner wall of the groove) and the motor 4 at intervals, as shown in fig. 2. The containing cavity of the motor cover 8 is communicated with the cavity of the volute.
The motor bracket 9 is provided with a mounting hole, the motor 4 is embedded in the mounting hole of the motor bracket 9, as shown in fig. 2, the motor bracket 9 is connected to the second side plate 2, and specifically, the periphery of the motor bracket 9 is fixed to the inner surface of the second side plate 2. The rotating shaft of the motor 4 is used for driving the impeller 5 to rotate, and the free end of the rotating shaft of the motor 4 faces the air inlet 6. The accommodating cavity of the motor cover 8 passes through the motor support 9 and is communicated with the cavity of the volute, namely, the structure of the motor support 9 does not completely isolate the accommodating cavity of the motor cover 8 from the cavity of the volute, so that the air flow can pass through the motor support 9 and flow between the accommodating cavity of the motor cover 8 and the cavity of the volute.
Because this fume exhaust fan embodiment is unilateral air inlet, when motor 4 drives impeller 5 and rotates, the air current only flows into the spiral case from air intake 6 of first curb plate 1, and does not have the air current to flow into the spiral case from motor cover 8 and second curb plate 2 (it is easy to say, motor cover 8 and second curb plate 2 do not set up the air current inflow mouth that supplies the air current to flow into the cavity of spiral case from the spiral case outside). When the motor 4 drives the impeller 5 to rotate, the flow direction of the airflow is approximately as shown by an arrow in fig. 2, and the airflow flows into the volute from the air inlet 6 of the first side plate 1 and finally flows out of the air outlet 7. When the motor 4 drives the impeller 5 to rotate, airflow can be formed between the accommodating cavity of the motor cover 8 and the cavity of the volute, and heat emitted by the motor 4 can flow along with the airflow and is discharged out of the air outlet 7 along with the airflow.
The foregoing is merely one embodiment of the present application and other embodiments may be devised by adding, deleting, modifying or replacing certain features. For example, the motor may be directly fixed to the second side plate, the second side plate is provided with a plurality of through holes distributed around the motor, and the accommodating cavity of the motor cover is communicated with the cavity of the volute through the through holes. For another example, the inner wall of the groove of the motor cover may be spherical. For another example, the device may further include a housing; the volute, the motor cover and the motor are all arranged in the casing, and the fixed frame of the volute is fixedly connected to the casing. For another example, the motor may be disposed outside the second side plate (i.e., the whole motor is disposed in the accommodating cavity of the motor cover), and only the rotating shaft of the motor passes through the second side plate and is connected to the impeller to drive the impeller to rotate.
The application still provides an oil smoke pump drainage subassembly embodiment, includes smoke ventilator and the supplementary oil extraction cigarette device that sets gradually from bottom to top. The auxiliary cooking fume extractor is preferably fixed above the ceiling of the kitchen. The smoke exhaust ventilator is fixed on the wall of the kitchen. The auxiliary oil smoke exhaust device is provided with the embodiment of the unilateral air inlet oil smoke exhaust fan. The auxiliary oil smoke discharging device is externally connected in series with a smoke discharging pipeline of the oil smoke exhauster. Specifically, the smoke exhaust pipeline of the range hood comprises a first smoke exhaust pipe and a second smoke exhaust pipe. The auxiliary oil smoke discharging device is arranged outside the body of the oil smoke exhauster. The air inlet 6 of the one-side air inlet fume exhaust fan embodiment of the auxiliary fume exhaust device is connected with the outlet of the first fume exhaust pipe, the air outlet 7 of the one-side air inlet fume exhaust fan embodiment of the auxiliary fume exhaust device is connected with the inlet of the second fume exhaust pipe, the inlet of the first fume exhaust pipe is connected with the air pipe seat of the body of the fume exhaust fan, and the outlet of the second fume exhaust pipe is connected with the inlet of the public flue on the wall of the kitchen. When the oil smoke pumping and exhausting assembly operates (namely when at least one of the oil smoke exhauster and the auxiliary oil smoke exhausting device operates), airflow exhausted by the body of the oil smoke exhauster sequentially flows through the first smoke exhausting pipe, the auxiliary oil smoke exhausting device and the second smoke exhausting pipe and then is exhausted into the common flue. When the oil smoke pumping and discharging assembly operates, heat emitted by a motor 4 of the single-side air inlet oil smoke discharging fan flows along with air flow and is discharged into a common flue.
A centrifugal fan is arranged in the body of the range hood, and therefore the range hood is characterized in that the range hood is provided with two centrifugal fans which are connected in series. One of the two centrifugal fans is located in the body of the range hood, and the other centrifugal fan is located in the auxiliary oil smoke exhaust device (the other centrifugal fan is the unilateral air inlet oil smoke exhaust fan of the auxiliary oil smoke exhaust device). The auxiliary fume exhaust device is one auxiliary device for raising fume exhaust effect of fume exhaust fan. The user can decide whether to add an auxiliary device for assisting the oil smoke exhaust device to the oil smoke exhaust device according to the actual condition of the user.
As for the control of the auxiliary range hood, it may be set to be independent from the control of the range hood, or set to be associated with the control of the range hood (for example, when the control device of the auxiliary range hood detects the operation of the fan of the range hood, the one-side air intake range hood fan of the auxiliary range hood is automatically started).
The elements of the different embodiments may be combined with each other in any feasible manner to achieve the object of the application.
