[ 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 embodiment of the range hood provided by the application is a top suction type range hood, and comprises a guide plate 1, a driving device, a smoke collection cavity 10, a fan and a casing 12, as shown in fig. 1 and 2. The fan is disposed in the casing 12. The housing 12 is connected to and disposed above the smoke collecting chamber 10, and as shown in fig. 1 and 2, the whole range hood is in an inverted T shape. The smoke collecting cavity 10 is provided with an exhaust port, a safety filter screen 11 is installed at the exhaust port, and the safety filter screen 11 is located below the fan. When the blower is operated, the airflow flowing into the smoke collecting cavity 10 flows into the casing 12 after passing through the safety filter 11. The safety filter 11 has an effect of filtering grease in the oil smoke, and can prevent a user from inserting a hand into the housing 12.
The guide plate 1 is arranged below the exhaust port of the smoke collection cavity 10; namely, the guide plate 1 is arranged below the safety filter screen 11 so as to contain the grease dropping from the safety filter screen 11. The baffle 1 includes a front side plate 2, a rear side plate 3, a left side plate 4, a right side plate 5, an oil cup 8, and a joint 9, as shown in fig. 1 to 3. The inner surface of the guide plate 1 is groove-shaped, and the outer surface is tile roof-shaped. The roof-shaped outer surface of the air deflector 1 is arranged facing downwards and the groove-shaped inner surface of the air deflector 1 is arranged facing upwards, as shown in fig. 1 and 2.
The front side plate 2 and the rear side plate 3 are both in the shape of a V-wing, and as shown in fig. 3, an included angle between a plane where the outer surface of the front side plate 2 is located and a plane where the outer surface of the rear side plate 3 is located is an obtuse angle. The left side plate 4 and the right side plate 5 are respectively located at the left end and the right end of the V-shaped wing-shaped structure, and the left side plate 4 and the right side plate 5 respectively plug V-shaped gaps at the left end and the right end of the V-shaped wing-shaped structure. The front side plate 2, the left side plate 4 and the right side plate 5 are all non-porous plates. The rear side plate 3 is provided with an air inlet 6, and a filter screen is arranged at the air inlet 6. The filter screen is detachably arranged at the air inlet 6. This filter screen is sheltered from by preceding curb plate 2 in the horizontal direction, promptly, if the user stands in smoke ventilator dead ahead, looks towards guide plate 1 along the horizontal direction, owing to sheltered from by preceding curb plate 2, this filter screen can't be seen to the user. The filter screen is the only area for air flow to pass through on the plate body of the guide plate 1 when the fan runs; that is, the filter screen is the only air intake channel provided in the baffle 1 itself. The filter screen is a plate-shaped filter screen 7, and the outer surface of the plate-shaped filter screen 7 is rectangular, as shown in fig. 2 and 3. The plate-shaped filter net 7 is in a suspended state in fig. 2 and is not installed at the air inlet 6.
The joining part 9 is joined and arranged between the front side plate 2 and the rear side plate 3. One side of the joining part 9 is joined to the bottom side of the front side plate 2, and the other side of the joining part 9, which is opposite to the front side, is joined to the bottom side of the rear side plate 3. Specifically, the joining portion 9 is located at a top ridge of the roof-shaped outer surface of the tile house, as shown in fig. 3 (the oil cup 8 is not yet installed on the baffle 1 shown in fig. 3), the outer surface of the joining portion 9 is arc-surface-shaped, so as to achieve smooth joining between the outer surface of the front side plate 2 and the outer surface of the rear side plate 3, edge lines of the joining portion 9 are shown by two dotted lines in fig. 3, and an "extending direction of the joining portion 9" is substantially a length direction of any one of the dotted lines. The left and right side panels 4, 5 are each inclined downwardly from top to bottom and gradually towards each other as shown in figures 1 and 2, thus facilitating the flow of grease to the joint 9.
The cup 8 is suspended from the joint 9 and the grease adhering to the filter screen will eventually flow into the cup 8. The oil cup 8 is in a strip shape, and the extending direction of the oil cup is parallel to the extending direction of the connecting part 9. The engaging portion 9 is provided with an oil leakage hole so that grease attached to the groove-shaped inner surface of the deflector 1 flows into the oil cup 8 through the oil leakage hole. The front side plate 2, the rear side plate 3 (without a filter screen), the left side plate 4, the right side plate 5 and the joint part 9 are integrally formed and are made of a metal plate through stamping.
The driving device is arranged to be suitable for driving the guide plate 1 to move up and down so as to switch between a first position and a second position. When the air deflector 1 is switched from the first position to the second position, the air deflector 1 rises. When the air deflector 1 is switched from the second position to the first position, the air deflector 1 descends. When the guide plate 1 is at the first position, an air inlet gap is formed between the guide plate 1 and the smoke collection cavity 10 at intervals. When the guide plate 1 is at the second position, the air inlet gap formed between the guide plate 1 and the smoke collection cavity 10 at intervals is reduced. Whether the guide plate 1 is in the first position or the second position, if the fan runs, a part of airflow flows through the plate-shaped filter screen 7 and then flows into the fan through the safety filter screen 11, and a part of airflow flows through the air inlet gap and then flows into the fan through the safety filter screen 11.
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, when the guide plate is in the second position, the air inlet gap is closed, and at this time, if the fan operates, the airflow flows into the fan through the safety filter screen after flowing through the plate-shaped filter screen. For another example, the left side plate and the right side plate may be respectively disposed vertically downward, in which case, the outer surface of the left side plate and the outer surface of the right side plate are parallel to each other.
The elements of the different embodiments may be combined with each other in any feasible manner to achieve the object of the application.
It should be additionally noted that the present application should not be construed as limited to the above-described embodiments, but rather should be construed to cover all possible embodiments as determined by the claims that follow when taken in conjunction with the disclosure herein. Therefore, any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the present application are within the protection scope of the present application, unless departing from the content of the present application.
