[0034] In order to make the purpose, scheme and beneficial effects of the present application more clear, the present application is further described below in conjunction with the accompanying drawings and preferred embodiments.
[0035] The present application proposes a side-suction range hood embodiment, comprising a housing 1, a fume hood 3 and an oil cup 2 arranged in sequence from top to bottom. Figures 1 to 3 As shown. The air flow channel in the smoke hood 3 is connected to the air flow channel in the housing 1. A fan is arranged in the air flow channel of the housing 1. The oil cup 2 is suspended at the bottom end of the smoke hood 3. The oil cup 2 is arranged to be suitable for receiving grease flowing down from the air flow channel in the smoke hood 3 and the air flow channel in the housing 1.
[0036] The side suction range hood comprises a smoke guide surface 4, such as Figures 1 to 3 Specifically, the smoke guiding surface 4 is the front wall surface of the smoke collecting hood 3. The angle α between the smoke guiding surface 4 and the horizontal plane is an acute angle.
[0037] The smoke guide surface 4 is provided with a side suction air inlet 5. The side suction air inlet 5 runs through the smoke guide surface 4 horizontally, and cuts the smoke guide surface 4 into two parts, such as an upper part and an lower part. Figures 1 to 3 The side suction air inlet 5 is roughly located at the inner side of the oil fume source and is used to achieve side suction.
[0038] A smoke guide plate is provided at the side air inlet 5, which is suitable for partially blocking the side air inlet 5. The smoke guide plate is in an arched shape protruding from the smoke guide surface 4, such as Figure 1 The inner surface of the smoke guide plate and the side suction air inlet 5 form an outer expansion smoke cavity, which protrudes outside the smoke guide surface 4.
[0039] The smoke guide plate is in the shape of a long strip. The smoke guide plate extends from the left end of the smoke guide surface 4 to the right end of the smoke guide surface 4. Figure 2As shown. The smoke guide plate is in the shape of a bent plate. The smoke guide plate includes an upper plate body 6 and a lower plate body 7 connected to each other. The upper plate body 6 and the lower plate body 7 are formed into an integral structure. Specifically, the upper plate body 6 and the lower plate body 7 are both glass integrally formed parts. The outer surface of the upper plate body 6 and the outer surface of the lower plate body 7 are smoothly transitioned. An angle β is formed between the upper plate body 6 and the lower plate body 7, and the angle β is an obtuse angle, such as Figure 4 Specifically, the angle β is 135°.
[0040] The angle β opens toward the side air inlet 5, such as Figure 1 Specifically, the opening of the angle β is arranged opposite to the side air inlet 5. The cross section of the smoke guide plate is V-shaped, and the upper plate body 6 and the lower plate body 7 respectively constitute the two sides of the "V-shape", as shown in FIG. Figure 4 shown.
[0041] The top edge of the side air inlet 5 and the upper edge of the smoke guide plate are spaced apart to form a top air flow inlet 8, such as Figures 1 to 3 As shown. The outer surface of the smoke guide plate is configured to guide the airflow to the top airflow inlet 8 based on the Coanda effect. The angle β is set to a rounded angle, so that the outer surface of the upper plate body 6 and the outer surface of the lower plate body 7 are smoothly transitioned to enhance the effect of the outer surface of the smoke guide plate guiding the airflow from bottom to top to the top airflow inlet 8 based on the Coanda effect. Coanda effect, also known as wall attachment effect or Coanda effect.
[0042] The left end of the smoke guide plate is spaced from the plane where the smoke guide surface 4 is located to form a left air inlet 9, such as Figure 1 The right end of the smoke guide plate is spaced from the plane where the smoke guide surface 4 is located to form a right air inlet. The angle between the "plane where the smoke guide surface 4 is located" and the horizontal plane is also α.
[0043] The side suction range hood includes a driving device for driving the smoke guide plate. The smoke guide plate is configured to rotate around its upper edge under the driving of the driving device and switch between a first position and a second position. The driving device includes a motor and a crank arm 11. The crank arm 11 has one end connected to the upper edge of the smoke guide plate and the other end connected to the motor. Figures 3 to 6 As shown, the motor is not shown in the figure. The motor is suitable for driving the crank arm 11 to rotate, and the rotating crank arm 11 drives the smoke guide plate to rotate synchronously.
[0044] When the smoke guide plate is in the first position, the upper edge and the lower edge of the smoke guide plate are both located at the side suction air inlet 5, and the smoke guide plate partially blocks the side suction air inlet 5. Figure 1 and 2 When the smoke guide plate switches from the first position to the second position, the lower edge of the smoke guide plate is lifted forward.
[0045] A filter screen 10 is provided at the lower edge of the smoke guide plate. When the smoke guide plate is in the first position, the free end of the filter screen 10 is located at the side suction air inlet 5. At this time, the filter screen 10 is suitable for guiding the grease attached to the smoke guide plate to the side suction air inlet 5. Figure 1 and 2 The filter screen 10 is attached and fixed to the inner wall of the lower plate body 7 and extends outside the lower plate body 7. The upper plate body 6, the lower plate body 7 and the filter screen 10 are arranged in sequence from top to bottom, as shown in FIG. Figure 4 shown.
[0046] When the smoke guide plate is in the first position, the angle β formed between the upper plate body 6 and the lower plate body 7 opens toward the side suction air inlet 5. Figure 1 shown.
[0047] When the smoke guide plate is in the first position, the left end of the smoke guide plate and the plane where the smoke guide surface 4 is located are spaced to form a left air inlet 9, and the right end of the smoke guide plate and the plane where the smoke guide surface 4 is located are spaced to form a right air inlet.
[0048] When the smoke guide plate is in the first position, the side-suction range hood is in the first working mode. Figure 1 and 2 As shown. At this time, if the fan is running, negative pressure is formed and airflow is generated. Part of the airflow passes through the left air inlet 9 and the right air inlet and flows into the outer expansion smoke chamber, and then passes through the side suction air inlet 5 and flows into the smoke hood 3. Part of the airflow passes through the filter 10 and the side suction air inlet 5 in sequence and flows into the smoke hood 3. Part of the airflow, under the action of the Coanda effect, flows along Figure 1 In the direction of the arrow in the figure, the air flows from bottom to top through the outer surface of the lower plate 7 and the outer surface of the upper plate 6 in sequence, and flows into the top airflow inlet 8, and then flows into the smoke hood 3. The airflow flowing into the smoke hood 3 further flows into the casing 1, and then is discharged into the public flue. It can be seen that when the side-suction range hood is in the first working mode, a circle of airflow inflow channels is formed around the smoke guide plate, achieving an all-round air intake effect.
[0049] When the smoke guide plate is in the second position, the side-suction range hood is in the second working mode. Figure 3 At this time, if the fan is running, negative pressure is formed, generating airflow. Part of the airflow flows into the smoke hood 3 through the side air inlet 5 exposed by the lower edge of the smoke guide plate being lifted forward. Part of the airflow, under the action of the Coanda effect, flows along the Figure 3 In the direction of the arrow in FIG. 1 , the air flows from bottom to top through the outer surface of the lower plate body 7 and the outer surface of the upper plate body 6 in sequence, and flows into the top air flow inlet 8, and then flows into the smoke collecting hood 3. The airflow flowing into the smoke collecting hood 3 further flows into the casing 1, and then is discharged into the public flue.
[0050] When the smoke guide plate is in the second position, the lower plate body 7 extends in the vertical direction, and the upper plate body 6 extends in the direction perpendicular to the plane where the smoke guide surface 4 is located. Figure 3 In other words, when the smoke guide plate is in the second position, the extension direction of the upper plate body 6 is substantially perpendicular to the plane where the smoke guide surface 4 is located. The sum of the angle α and the angle β is 180°.
[0051] According to another embodiment, the angle β formed between the upper plate body 6 and the lower plate body 7 is a right angle.
[0052] According to another embodiment, the angle α between the smoke guiding surface 4 and the horizontal plane is a right angle.
[0053] According to another embodiment, the side suction range hood is not provided with a driving device, and the smoke guide plate is always in a state of operation. Figure 1 and 2 In other words, the side suction range hood embodiment is only Figure 1 and 2 This is a working mode.
[0054] The components of different embodiments may be combined with each other in any feasible manner to achieve the purpose of this application.
[0055] It should be noted that the present application should not be understood as being limited to the above-described implementation methods, but should be understood as covering all possible implementations determined by the claims of the present application in combination with the disclosure of the specification. Therefore, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present application without departing from the content of the technical solution of the present application shall fall within the protection scope of the technical solution of the present application.
