[0025] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:
[0026] This utility model discloses a smoke hood. Please refer to [link / reference]. Figures 1 to 4The range hood proposed in this utility model includes a housing 1, an exhaust device 2, and an oil cup 3. The housing 1 has an exhaust panel 11 and a smoke collection chamber located inside the exhaust panel 11. The exhaust panel 11 has a smoke collection chamber 111, and a first exhaust port 12 is provided in the smoke collection chamber 111. The first exhaust port 12 is connected to the smoke collection chamber. The exhaust device 2 draws in oil fumes through the first exhaust port 12 and discharges the oil fumes into the smoke collection chamber. The oil cup 3 is connected to the housing 1 and is used to receive the oil discharged from the smoke collection chamber.
[0027] In this embodiment, the range hood also includes an exhaust box installed on the top of the housing 1. The exhaust box is connected to the smoke collection chamber. An exhaust device 2 is installed inside the exhaust box. An exhaust port is opened on the top of the exhaust box. The exhaust device 2 is used to provide the power required for the range hood to suck up the fumes. After the exhaust device 2 is started, it will generate negative pressure in the smoke collection chamber, which will drive the air to flow. The fumes in the kitchen will be sucked into the smoke collection chamber from the first air intake 12, and then flow further to the exhaust box and be discharged from the exhaust port.
[0028] The smoke collection chamber 111 can be formed by the outer side of the suction panel 11 recessed towards the smoke collection chamber. The first air intake 12 is opened at the deepest part of the smoke collection chamber 111. The smoke collection chamber 111 is opened on the suction panel 11, and the first air intake 12 is set in the smoke collection chamber 111. The oil fumes rushing towards the suction panel 11 will first enter the smoke collection chamber 111 and then flow into the first air intake 12. The smoke collection chamber 111 can play a role in collecting oil fumes and prevent oil fumes from easily escaping from the area near the first air intake 12, so as to increase the residence time of oil fumes near the first air intake 12, so that more and more oil fumes can be sucked in by the first air intake 12, thereby improving the smoke extraction effect of the range hood.
[0029] The oil cup 3 is connected to the bottom of the housing 1. The opening of the receiving cavity of the oil cup 3 faces upward and is connected to the smoke collection cavity. The oil accumulated in the smoke collection cavity and the oil dripping from the exhaust device 2 into the smoke collection cavity will flow to the oil cup 3 under the action of gravity, so as to realize the oil cup 3 to receive and collect the oil.
[0030] The smoke hood of this utility model, such as Figures 2 to 4 As shown, the suction panel 11 includes a first part a extending from front to back and a second part b extending from top to bottom, and the smoke collection chamber 111 is disposed on the first part a.
[0031] The rear side of the first part a is connected to the top side of the second part b. Both the smoke collection chamber 111 and the first air intake 12 are located in the first part a, with the opening of the smoke collection chamber 111 facing downwards and the first air intake 12 located at the highest point of the smoke collection chamber 111. Since cooking fumes typically flow upwards, placing the smoke collection chamber 111 in the first part a allows the upward-flowing fumes to more easily enter the chamber and makes it less likely for fumes already flowing into it to flow out, thus enabling more fumes to be drawn in more thoroughly by the first air intake 12, thereby further improving the range hood's fume extraction efficiency.
[0032] The smoke hood of this utility model, such as Figures 1 to 3 As shown, a second air intake 13 is provided on the second part b, located on the lower half of the second part b, and is connected to the smoke collection chamber. After the exhaust device 2 is activated, a negative pressure is generated at the second air intake 13, allowing some of the oil fumes to be drawn into the smoke collection chamber, thus increasing the efficiency of oil fume extraction. Positioning the second air intake 13 on the lower half of the second part b ensures a certain distance between it and the first air intake 12, preventing the negative pressure at the first air intake 12 from interfering with the negative pressure at the second air intake 13, thereby guaranteeing the effective extraction of oil fumes.
[0033] The smoke hood of this utility model, such as Figures 1 to 3 As shown, a guide plate 131 is provided on the upper edge of the second air intake 13. The guide plate 131 is inclined from top to bottom and located in the smoke collection chamber. The guide plate 131 is provided with air passage holes 1311. Oil fumes will adhere and accumulate on the back side of the second part b in the smoke collection chamber 111, forming oil. The oil will flow downward under the action of gravity. The oil above the second air intake 13 will flow onto the guide plate 131 and flow backward along the guide plate 131. After flowing to the rear side of the guide plate 131, it will drip downward. In this way, the oil can be prevented from flowing out of the second air intake 13, thus preventing the range hood from overflowing. The air passage holes 1311 allow the airflow passing through the second air intake 13 to pass through the guide plate 131, thereby reducing the obstruction of the airflow by the guide plate 131 and ensuring the airflow velocity at the second air intake 13.
[0034] The smoke hood of this utility model, such as Figures 1 to 3 As shown, the first part a and the second part b are integrally formed, and a third part c is provided between the two. The third part c is arc-shaped, and the upper edge of the third part c connects to the rear edge of the first part a, and the lower edge of the third part c connects to the upper edge of the second part b.
[0035] The first part a, the second part b, and the third part c are integrally formed. The third part c connects the rear edge of the first part a to the upper edge of the second part b. The oil fume that rushes towards the second part b will flow upward along the second part b, turn after flowing through the third part c, and then flow along the first part a to the smoke collection chamber 111. The third part c is set in a concave arc shape, which can make the turning process of the oil fume when flowing through the third part c smoother and more natural, so as to ensure the flow rate of the oil fume after turning.
[0036] The smoke hood of this utility model, such as Figures 1 to 2As shown, the smoke collection chamber 111 includes a front side 1111, a rear side 1112, a left side 1113, a right side 1114, and a bottom surface 1115. The front side 1111 is inclined backward from bottom to top, and the rear side 1112 is inclined forward from bottom to top. The front edge and rear edge of the bottom surface 1115 are connected to the upper edge of the front side 1111 and the upper edge of the rear side 1112, respectively. The left side 1113 connects the left side of the front side 1111, the rear side 1112, and the bottom surface 1115, and the right side 1114 connects the right side of the front side 1111, the rear side 1112, and the bottom surface 1115.
[0037] The front side 1111, rear side 1112, left side 1113, and right side 1114 are all set at obtuse angles to the bottom surface 1115. In this way, the length and width of the smoke collection chamber 111 gradually decrease from bottom to top. This can maximize the volume of the smoke collection chamber 111 to increase the amount of oil fumes that the smoke collection chamber 111 can hold, and also reasonably control the suction area of the first air intake 12 so that the oil fumes have a sufficient flow rate when they flow through the first air intake 12.
[0038] The smoke hood of this utility model, such as Figures 1 to 2 As shown, the suction panel 11 has a mounting position located on the front side of the smoke collection chamber 111, and a light 4 is installed in the mounting position. The light 4 emits light downwards to illuminate the area where the user is located, thereby assisting the user in the cooking process and improving the performance of the range hood.
[0039] The smoke hood of this utility model, such as Figures 2 to 4 As shown, the front edge of the first part a extends downward from back to front with a first extension plate 112, and the lower edge of the first extension plate 112 extends forward with a second extension plate 113. The second extension plate 113 forms a height difference with the plane where the first part a is located, so that the first extension plate 112 forms a smoke-collecting plate.
[0040] The first extension plate 112 extends forward and downward from the leading edge of the first part a, and the second extension plate 113 extends forward from the leading edge of the first extension plate 112. The first part a is concave relative to the second extension plate 113, so that the first extension plate 112 forms a smoke-collecting plate. The smoke-collecting plate can block the oil fumes that rush towards the first part a and flow forward along the first part a, so as to prevent these oil fumes from escaping easily. This can prolong the time that oil fumes that do not have time to be sucked in by the first air intake 12 stay near the smoke-collecting cavity 111, so that more oil fumes can be sucked in by the first air intake 12.
[0041] The smoke hood of this utility model, such as Figure 4As shown, a connecting portion 114 extends upward from the leading edge of the second extension plate 113. A control panel assembly 5 is mounted on the front side of the housing 1, and the connecting portion 114 connects to the control panel assembly 5. The control panel assembly 5 is used by the user to control the operation of the range hood, such as controlling the opening or closing of the range hood and the speed setting of the exhaust device 2. The connecting portion 114 connects to the control panel assembly 5 and provides support and fixation for the control panel assembly 5, thereby improving the installation stability of the control panel assembly 5.
[0042] The smoke hood of this utility model, such as Figures 1 to 3 As shown, the range hood also includes side baffles 6, which are located on the left and right sides of the housing 1; or the housing 1 has a side plate 14, with an installation groove 141 on the inner side of the side plate 14, and the side baffles 6 are installed in the installation groove 141. There are two side baffles 6, which are located on the left and right sides of the housing 1 respectively. The area between the two side baffles 6 is the smoke collection area. The side baffles 6 play a certain role in blocking and guiding the fumes, preventing the fumes from moving directly away from the smoke collection area, thereby prolonging the residence time of the fumes near the air inlet and allowing the fumes to be fully drawn into the air inlet.
[0043] By directly connecting the side baffle 6 to the side plate 14, the side baffle 6 can be installed on the housing 1. Since the side baffle 6 is directly connected to the side plate 14 rather than to the front or bottom plate of the housing 1, the shear force on the front or bottom plate is reduced, preventing easy deformation of the front or bottom plate. For the side plate 14, connecting the side baffle 6 to the side plate 14 does not increase the shear force on the side plate 14, thus preventing easy deformation. This improves the structural stability of the housing 1 of the range hood. The mounting groove 141 extends along the front edge of the side plate 14, increasing the mating area between the side baffle 6 and the side plate 14, thereby improving the connection stability between the side baffle 6 and the side plate 14. The groove wall of the mounting groove 141 also provides positioning for the side baffle 6, preventing it from easily shifting.
[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
