Description

Technical Field

[0001] This invention relates to the field of integrated stove technology, and in particular to a range hood head and an integrated stove. Background Technology

[0002] The smoke vents of existing integrated cooktops are typically located to the side or above the cooktop. The position of the smoke vent relative to the cooktop cannot be adjusted according to specific cooking conditions, making it difficult to meet the complex needs of Chinese cooking. Specifically, Chinese cooking usually includes steaming and stir-frying modes. On the one hand, the pots used for steaming are higher than those used for stir-frying. On the other hand, steaming generates a large amount of steam, while stir-frying generates a large amount of oil fumes. A fixed smoke vent cannot adequately meet the exhaust requirements of both steaming and stir-frying in Chinese cooking.

[0003] In response, a previous patent application with application number CN201822016023.8 disclosed an integrated stove in which the upper suction chamber is hinged to the upper part of the rear suction channel via a rotating component. Depending on the specific cooking situation, the upper suction chamber can be moved and rotated to adjust the suction position. This allows the upper suction chamber to be positioned above the stove for stir-frying mode, or to be positioned to the side of the stove for steaming mode. However, this integrated stove still has the following problem: the area of ​​the smoke inlet of its upper suction chamber is constant and difficult to adjust according to different cooking modes. Summary of the Invention

[0004] The purpose of this invention is to provide a range hood head and an integrated stove to solve the problem that the area of ​​the smoke inlet of the upper air intake chamber of the existing integrated stove is constant and difficult to adjust according to different cooking modes.

[0005] On one hand, the present invention provides a range hood head, the range hood head comprising:

[0006] Rear panel;

[0007] The front panel can slide back and forth in the vertical direction relative to the rear panel. The front panel and the rear panel form a smoke exhaust chamber. The smoke inlet end of the front panel and the smoke inlet end of the rear panel form a smoke inlet that communicates with the smoke exhaust chamber. As the front panel moves from top to bottom relative to the rear panel, the area of ​​the smoke inlet gradually increases.

[0008] As a preferred technical solution for the range hood head, the range hood head further includes an oil mesh structure disposed at the smoke inlet, the oil mesh structure comprising:

[0009] A fixed oil filter is fixedly installed at the smoke inlet end of the front panel;

[0010] The movable oil screen has one side rotatably connected to the smoke inlet end of the rear panel, and the other side is always slidably abutting against the fixed oil screen. The fixed oil screen and the movable oil screen together cover the smoke inlet.

[0011] As a preferred technical solution for the range hood head, the smoke inlet end of the front panel is located at the top of the front panel, and the smoke inlet end of the rear panel is located at the top of the rear panel.

[0012] The front end plate can reciprocate in the vertical direction relative to the rear end plate to have an upper position and a lower position. When the front end plate moves from the upper position to the lower position, the included angle between the movable oil mesh and the fixed oil mesh gradually decreases as the area of ​​the smoke inlet changes.

[0013] As a preferred technical solution for the range hood head, the fixed oil screen is horizontally arranged, and when the front end plate is located in the upper position, the movable oil screen is parallel to the fixed oil screen.

[0014] As a preferred technical solution for the range hood head, the range hood head also includes a smoke baffle. The bottom end of the smoke baffle is fixedly connected to the movable oil screen. The top end of the smoke baffle is tilted forward relative to the bottom end of the smoke baffle. When the front end plate moves from the upper position to the lower position, the angle of the forward tilt of the top end of the smoke baffle relative to the bottom end of the smoke baffle gradually decreases.

[0015] As a preferred technical solution for the range hood head, the fixed oil screen is located below the movable oil screen;

[0016] During the reciprocating motion of the front panel relative to the rear panel in the vertical direction, the side of the movable oil mesh slides against the fixed oil mesh under the overall gravity of the movable oil mesh and the smoke baffle.

[0017] As a preferred technical solution for the range hood head, the fixed oil screen is provided with an oil leakage hole that communicates with the exhaust chamber.

[0018] As a preferred technical solution for the range hood head, smoke-gathering wings are respectively provided at the left and right ends of the movable oil screen. Both smoke-gathering wings are slidably engaged with the rear panel, and both smoke-gathering wings are at least partially located inside the smoke exhaust chamber.

[0019] As a preferred technical solution for the range hood head, the range hood head further includes a first driving mechanism, which is connected to the front end plate in a transmission manner, and the first driving mechanism can drive the front end plate to slide back and forth in the vertical direction relative to the rear end plate.

[0020] On the other hand, the present invention provides an integrated stove, including a range hood head as described in any of the above-mentioned solutions. The integrated stove also includes a duct box and a cooker disposed on the front side of the duct box. The range hood head is disposed above the duct box. The exhaust end of the front panel and the exhaust end of the rear panel are arranged to form an exhaust port communicating with the exhaust chamber. The exhaust port is communicating with the inner cavity of the duct box.

[0021] The range hood head provided by this invention has at least the following beneficial effects:

[0022] The range hood head includes a rear panel and a front panel. The front panel can slide back and forth vertically relative to the rear panel. The front and rear panels form a smoke exhaust chamber. The smoke inlet ends of the front and rear panels form a smoke inlet that communicates with the smoke exhaust chamber. As the front panel moves from top to bottom relative to the rear panel, the area of ​​the smoke inlet gradually increases. When stir-frying, the front panel can be moved to the bottom relative to the rear panel, at which point the smoke inlet area is at its largest, maximizing the range of smoke absorption and minimizing the effective height of the smoke inlet, making it ideal for stir-frying and maximizing smoke absorption. When steaming or boiling, the front panel can be moved to the top relative to the rear panel, at which point the smoke inlet area is at its smallest and the smoke inlet height is at its highest, making it suitable for steaming or boiling and facilitating the absorption of moisture, thus meeting the needs of different cooking modes.

[0023] The integrated stove provided by this invention has at least the following beneficial effects:

[0024] This integrated cooktop includes the aforementioned range hood head, duct housing, and cooktop. It also includes the duct housing and the cooktop positioned at the front of the duct housing. The range hood head is located above the duct housing, with one exhaust end of the front panel and one exhaust end of the rear panel forming an exhaust port that communicates with the exhaust chamber. The exhaust port is connected to the inner cavity of the duct housing. The height and area of ​​the exhaust port of the range hood head are adjustable to meet the needs of different cooking modes.

[0040] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0041] Please refer to Figures 1 to 4 This embodiment provides an integrated stove, which includes a range hood head 1, a duct housing 2, and a cooktop 3. The range hood head 1 is positioned above the duct housing 2, and its exhaust port is connected to the inner cavity of the duct housing 2. The cooktop 3 is located at the front of the duct housing 2. Specifically, the cooktop 3 can be an existing gas stove or an induction cooktop. The cooktop 3 can be used with a steamer or wok for cooking. During cooking, the fumes and / or moisture generated are drawn into the range hood head 1 through its exhaust port under the negative pressure provided by the fan in the duct housing 2, and then enter the duct housing 2 through its exhaust port, effectively purifying the cooking environment.

[0042] Please refer to Figure 5 and Figure 6In this embodiment, the smoke machine head 1 includes a rear panel 11 and a front panel 12. The front panel 12 can slide back and forth in the vertical direction relative to the rear panel 11. The front panel 12 and the rear panel 11 form a smoke exhaust chamber. The smoke inlet end of the front panel 12 and the smoke inlet end of the rear panel 11 form a smoke inlet that communicates with the smoke exhaust chamber. As the front panel 12 moves from top to bottom relative to the rear panel 11, the area of ​​the smoke inlet gradually increases. When stir-frying, the front panel 12 can be moved to its lowest position relative to the rear panel 11. At this point, the smoke inlet area is at its maximum, maximizing the range of smoke absorption and minimizing the effective height, making it ideal for stir-frying cookware and achieving optimal smoke absorption. When steaming or boiling, the front panel 12 can be moved to its highest position relative to the rear panel 11. At this point, the smoke inlet area is at its minimum, and the height is at its maximum, making it suitable for steaming or boiling cookware. This facilitates the absorption of moisture and meets the needs of different cooking modes, accommodating the smoke and moisture emission requirements of both steaming and stir-frying in Chinese cooking. Specifically, the vertical direction is as follows... Figure 1 As shown in the ab direction, the left and right directions are as follows. Figure 1 As shown in the cd direction, the forward and backward directions are as follows: Figure 1 The ef direction is shown in the figure.

[0043] Alternatively, please continue to refer to Figure 5 and Figure 6 The range hood head 1 also includes an oil mesh structure disposed at the smoke inlet. The oil mesh structure includes a fixed oil mesh 13 and a movable oil mesh 14. The fixed oil mesh 13 is fixedly disposed at the smoke inlet end of the front end plate 12. One side of the movable oil mesh 14 is rotatably connected to the smoke inlet end of the rear end plate 11, and the other side slides against the fixed oil mesh 13. The fixed oil mesh 13 and the movable oil mesh 14 together cover the smoke inlet. When the front end plate 12 reciprocates vertically relative to the rear end plate 11, the fixed oil mesh 13 moves synchronously with the front end plate 12. At this time, the sliding contact position between the movable oil mesh 14 and the fixed oil mesh 13 will change. To maintain a constant connection, the movable oil mesh 14 will rotate relative to the rear end plate 11 to match the change in the smoke inlet area. Specifically, in this embodiment, the movable oil mesh 14 is rotatably connected to the rear end plate 11 through a pivot shaft 20.

[0044] Alternatively, please refer to Figure 6 In this embodiment, the fixed oil mesh 13 is provided as an example of an integrated structure. Specifically, the movable oil mesh 14 includes a separate oil mesh support 141 and an oil mesh plate 142. The oil mesh plate 142 is detachably mounted on the oil mesh support 141. One side of the oil mesh support 141 is rotatably connected to the rear panel 11, and the other side of the oil mesh support 141 is slidably abutted against the fixed oil mesh 13. This arrangement facilitates the disassembly, assembly, and maintenance of the oil mesh plate 142. In other embodiments, the movable oil mesh 14 can also be configured as an integrated structure, and the fixed oil mesh 13 can be configured as a separate structure, as needed.

[0045] Alternatively, please refer to Figures 3 to 6 The smoke inlet end of the front panel 12 is located at the top of the front panel 12, and the smoke inlet end of the rear panel 11 is located at the top of the rear panel 11. The front panel 12 can reciprocate vertically relative to the rear panel 11, having an upper position and a lower position. When the front panel 12 moves from the upper position to the lower position, the angle between the movable oil mesh 14 and the fixed oil mesh 13 gradually decreases as the area of ​​the smoke inlet changes. With this configuration, the smoke inlet faces upward, allowing the filtered oil on the fixed oil mesh 13 and the movable oil mesh 14 to drip into the exhaust chamber, preventing it from dripping onto the surface of the stove 3. Of course, in other embodiments, the smoke inlet can also be opened towards the front as needed. Preferably, the fixed oil mesh 13 is horizontally arranged. When the front panel 12 is in the upper position, the movable oil mesh 14 is parallel to the fixed oil mesh 13, and the angle between the movable oil mesh 14 and the fixed oil mesh 13 is 180°. At the same time, the area of ​​the smoke inlet is also minimized, which is suitable for absorbing moisture in the steaming mode. When the front end plate 12 is in the lower position, the included angle between the movable oil mesh 14 and the fixed oil mesh 13 can be 140°, 135°, 130°, 125° or 120°, etc.

[0046] Alternatively, please continue to refer to Figure 5 and Figure 6 The range hood head 1 also includes a smoke baffle 16, the bottom end of which is fixedly connected to the movable oil mesh 14. The top end of the smoke baffle 16 is tilted forward relative to the bottom end, and as the front end plate 12 moves from the upper position to the lower position, the angle of the forward tilt of the top end of the smoke baffle 16 relative to the bottom end gradually increases. With this configuration, when the front end plate 12 is in the lower position, the angle of the forward tilt of the top end of the smoke baffle 16 relative to the bottom end reaches its maximum, which is suitable for stir-frying mode. Specifically, in this embodiment, when the front end plate 12 is in the upper position, the angle between the smoke baffle 16 and the vertical plane is a relatively small angle, the top of the smoke baffle 16 tilts forward slightly relative to the bottom of the smoke baffle 16, and the smoke baffle 16 does not extend directly above the stove 3. At this time, an open space will be formed directly above the stove 3, which will not affect the user's operating space and field of vision, and is conducive to the timely discharge of water vapor in the steaming mode. When the front end plate 12 is in the lower position, the angle between the smoke baffle 16 and the vertical plane is a relatively large angle, the smoke baffle 16 partially extends into the top of the stove 3, and the top of the smoke baffle 16 tilts forward significantly relative to the bottom of the smoke baffle 16.

[0047] Alternatively, please continue to refer to Figure 5 and Figure 6The fixed oil mesh 13 is located below the movable oil mesh 14. During the reciprocating sliding of the front end plate 12 relative to the rear end plate 11 in the vertical direction, the side of the movable oil mesh 14 slides against the fixed oil mesh 13 under the overall gravity of the movable oil mesh 14 and the smoke baffle 16. Specifically, in this embodiment, the top side of the movable oil mesh 14 is rotatably connected to the rear end plate 11, and the bottom side of the movable oil mesh 14 slides against the upper surface of the fixed oil mesh 13. The center of gravity of the movable oil mesh 14 and the smoke baffle 16 is located between the bottom side of the movable oil mesh 14 and the top side of the movable oil mesh 14. In this way, the overall gravity of the movable oil mesh 14 and the smoke baffle 16 can make one side of the movable oil mesh 14 always slide against the fixed oil mesh 13. In other embodiments, a counterweight can be set so that one side of the movable oil net 14 always slides against the fixed oil net 13; or, a spring can be set so that one side of the movable oil net 14 always slides against the fixed oil net 13. In this case, the fixed oil net 13 is not limited to being located below the movable oil net 14. For example, the fixed oil net 13 can be located above the movable oil net 14.

[0048] It should be noted that in this embodiment, the movable oil mesh 14 has a certain width in the front-to-back direction. The front side of the movable oil mesh 14 always slides against the upper surface of the fixed oil mesh 13. This causes the part of the fixed oil mesh 13 located between the front side of the movable oil mesh 14 and the front plate 12 to be directly exposed to the outside in the vertical direction. This part plays a substantial filtering role for the oil fumes or water vapor that just enters the smoke inlet. However, the part of the fixed oil mesh 13 located between the front side of the movable oil mesh 14 and the rear side of the movable oil mesh 14 is blocked by the movable oil mesh 14 in the vertical direction. This part does not play a filtering role for the oil fumes or water vapor that just enters the smoke inlet.

[0049] Optionally, the fixed oil mesh 13 is provided with an oil drain hole communicating with the exhaust chamber. With this arrangement, most of the oil accumulated on the movable oil mesh 14 will flow into the fixed oil mesh 13, and together with the oil accumulated on the fixed oil mesh 13, flow into the exhaust chamber through the oil drain hole, thereby reducing oil accumulation on the surface of the oil mesh structure. In other embodiments, the relative height of the fixed oil mesh 13 and the movable oil mesh 14 can also be set as needed.

[0050] Alternatively, please continue to refer to Figure 5 and Figure 6 The movable oil mesh 14 is provided with smoke-gathering wings 17 at both its left and right ends. Both smoke-gathering wings 17 are slidably engaged with the rear panel 11, and both smoke-gathering wings 17 are at least partially located within the smoke exhaust chamber. Specifically, both smoke-gathering wings 17 are provided on the oil mesh support 141, and are located at the left and right ends of the oil mesh support 141, respectively. This arrangement ensures the sealing of the smoke inlet when the movable oil mesh 14 rotates relative to the rear panel 11.

[0051] Alternatively, please continue to refer to Figure 5 and Figure 6 The range hood head 1 also includes a guide rail extending vertically and a slider slidably connected to the guide rail. One of the guide rail and the slider is disposed on the front end plate 12, and the other is disposed on the rear end plate 11. This arrangement ensures the stability of the front end plate 12 during sliding relative to the rear end plate 11. Preferably, the guide rail and the slider can be arranged in groups, and multiple groups can be configured to further ensure the stability of the front end plate 12 during sliding relative to the rear end plate 11.

[0052] Alternatively, please refer to Figure 7 The range hood head 1 also includes a first drive mechanism 15, which is connected to the front end plate 12 and can drive the front end plate 12 to slide back and forth in the vertical direction relative to the rear end plate 11. This enables the automatic lifting and lowering of the front end plate 12. To ensure smooth movement of the front end plate 12, multiple first drive mechanisms 15 can be set at intervals; or one first drive mechanism 15 can be set and cooperated with at least one sliding guide mechanism, such as a combination of a guide rod and a sliding sleeve. In this embodiment, the first drive mechanism 15 can be simply a linear drive motor or cylinder capable of linear motion output, or it can be a rotary drive motor cooperated with a reversing mechanism of a lead screw and nut, the output end of which can achieve up and down movement.

[0053] Alternatively, please continue to refer to Figure 7 The first drive mechanism 15 is disposed within the inner cavity of the air duct housing 2, with the front end plate 12 partially located within the inner cavity, and the front end plate 12 slidingly engaging with the air duct housing 2. This arrangement allows for efficient use of the internal space of the air duct housing 2, which is beneficial for improving the integration of the integrated stove. Of course, in other embodiments, the first drive mechanism 15 can also be installed on the rear panel 11 as needed.

[0054] Alternatively, please refer to Figure 5 , Figure 6 and Figure 8 The range hood head 1 also includes a light source 18, which is located on the front panel 12 with its optical axis facing the baffle plate 16. This arrangement allows the light from the light source 18 to be reflected by the baffle plate 16, preventing direct light and improving the user's cooking experience. Specifically, the light source 18 is located on the back of the front panel 12. This arrangement prevents the light source 18 from being exposed, making the overall design of the integrated stove more aesthetically pleasing. Furthermore, the light source 18 is not visible to the user during cooking, further enhancing the cooking experience.

[0055] Alternatively, please refer to Figure 8The range hood head 1 also includes a second drive mechanism 19, which drives the light source 18 to rotate relative to the front end plate 12. This configuration allows for adjustment of the reflective angle of the smoke baffle 16 as needed, further enhancing user convenience during cooking. Specifically, the second drive mechanism 19 includes a motor 191 fixed to the front end plate 12, a rotating shaft 192 driven by the motor 191, and a bracket 193 rotatably connected to the rotating shaft 192 and mounted on the front end plate 12. The light source 18 includes a light strip laid along the length of the rotating shaft 192. When the motor 191 rotates, the rotating shaft 192 drives the light strip to rotate, thereby adjusting the angle of the light strip's optical axis and matching changes in the forward tilt of the smoke baffle 16. Preferably, sound-absorbing material is provided between the motor 191 and the front end plate 12 to reduce noise generated by the motor 191 during operation. The sound-absorbing material can be noise-reducing cotton, etc. More preferably, the integrated stove also includes a two-way adjustment button, which has two positions: increase and decrease. The rotation angle of the motor 191 can be increased or decreased by the two-way adjustment button. Specifically, each time the two-way adjustment button is touched, the rotation angle of the motor 191 increases or decreases by a fixed value.

[0056] Alternatively, please refer to Figure 7 The duct housing 2 includes a housing shell 21 and an air duct 22. The housing shell 21 has an inner cavity, and its top has an opening communicating with the inner cavity. A front end plate 12 extends into the opening and is partially located within the inner cavity, and the front end plate 12 slides within the housing shell 21. The air duct 22 is located inside the housing shell 21 and is used to connect to a fan. To facilitate maintenance of the components inside the housing shell 21, in this embodiment, the housing shell 21 includes a rear housing 211 and a front air duct baffle 212, which together form the inner cavity. The air duct 22 is specifically installed in the rear housing 211, and the first drive mechanism 15 is specifically installed in the front air duct baffle 212. Preferably, the duct housing 2 also includes several adjusting bases 23 threadedly connected to the rear housing 211, which facilitate leveling of the duct housing 2 according to the actual ground conditions.
