Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a panel assembly for a range hood and a range hood. Background Art

[0002] Range hoods are a common appliance in modern kitchens. To enhance ease of use and overall aesthetics, current range hoods often feature an opening and closing panel at the air inlet. To prevent the panel from obstructing the user's view or occupying additional operating space when open, some range hoods have optimized the panel's trajectory. This panel is typically controlled inward by a drive mechanism, allowing it to be concealed within the main body of the range hood when open. This prevents the user from observing cooking activities and reduces the risk of collision between the panel and the user, thereby improving the user experience.

[0003] However, when a range hood with a concealed panel is in operation, oil smoke is drawn in through the hidden area of ​​the panel. If the decorative surface of the panel is exposed to the oil smoke passage, the oil smoke will easily condense and adhere to the surface of the panel, causing oil stains to accumulate, which not only affects the aesthetics of the range hood but also increases the difficulty of cleaning.

[0004] Therefore, how to reduce the adhesion of oil smoke to the opening and closing panels becomes a technical problem that needs to be solved in this application. Summary of the Invention

[0005] The present application provides a panel assembly for a range hood and a range hood to solve the problem of oil smoke adhesion on an opening and closing panel.

[0012] Furthermore, when the opening and closing plate is in the open state, the oil guide strip extends obliquely toward the inside of the air inlet.

[0013] Furthermore, the oil guide strip can be flush with the panel surface at the air inlet.

[0035] In order to solve the technical problem in the prior art that the opening and closing panels of range hoods are easily adhered to oil smoke, the present application provides a panel assembly for a range hood, which can achieve the effect of reducing the adhesion of oil smoke to the opening and closing panels.

[0036] Firstly, Figures 1 to 5 A panel assembly provided in an embodiment of the present application includes a panel, an opening and closing plate and a driving mechanism, wherein: the panel is used as a part of a smoke hood, wherein the panel is provided with an air inlet; the opening and closing plate matches the size of the air inlet, and the opening and closing plate has a decorative surface that can be flush with the surface of the panel; the driving mechanism includes a driving unit and a connecting rod mechanism, the driving unit is installed on the inner side of the panel, one end of the connecting rod mechanism is connected to the opening and closing plate, and the other end is connected to the driving unit; the driving mechanism is configured to drive the opening and closing plate to move through the connecting rod mechanism under the drive of the driving unit, so that the opening and closing plate can be switched between an open state in which the air inlet is opened and a closed state in which the air inlet is closed, wherein in the open state the opening and closing plate is located below the air inlet in the vertical direction, and the decorative surface is inclined downward.

[0037] In the technical solution of this application, panel 101 serves as part of the range hood's fume collection hood and is provided with an air inlet 106 for admitting cooking fumes into the range hood's internal oil fume duct and subsequently exhausting them outdoors. The opening and closing plate 102 matches the dimensions of the air inlet 106. When closed, the opening and closing plate 102 completely encloses the air inlet 106, and its surface is flush with the surface of the panel 101.

[0038] The drive mechanism includes a drive unit and a connecting rod mechanism. The drive unit can be in the form of a motor, a cylinder, or other suitable form, without limitation, as long as it can drive the connecting rod to move. The drive unit can be installed on the inner side of the panel 101, adjacent to the air inlet 106. There can be one or more drive units, without limitation, as long as they correspond to the connecting rod mechanism and provide power to the connecting rod mechanism.

[0039] The connecting rod mechanism may include one or more, for example, a connecting rod mechanism may be provided below the middle of the air inlet 106, with one end of the connecting rod mechanism connected to the middle of the opening and closing plate 102; or, two connecting rod mechanisms may be provided, each installed on either side of the air inlet 106, and the two connecting rod mechanisms are connected to both ends of the opening and closing plate 102, in which case two driving units may be provided to be connected to the two connecting rod mechanisms, or a driving unit may be provided below the middle of the air inlet 106 and connected to the two connecting rod mechanisms via a transmission rod, etc., without limitation here, as long as the movement of the opening and closing plate 102 can be stably controlled. One end of the connecting rod mechanism is connected to the back of the opening and closing plate, and the other end is connected to the driving unit, so that the driving unit operates the opening and closing plate 102 to move through the connecting rod mechanism. The connecting rod mechanism may be in the form of multiple links to drive the opening and closing plate to achieve an ideal motion trajectory, so that the opening and closing plate 102 can be switched between an open state of opening the air inlet 106 and a closed state of closing the air inlet 106.

[0040] When open, the opening and closing plate 102 is located on the back of the panel 101 and below the air inlet 106, preventing the oil smoke passage from directly contacting the opening and closing plate, thereby effectively reducing oil smoke pollution. Preferably, the decorative surface of the opening and closing plate 102 can be tilted downward to further prevent the decorative surface of the opening and closing plate 102 from contacting oil smoke.

[0041] In order to facilitate the installation of the drive unit and the connecting rod mechanism, according to a preferred embodiment, Figure 1 As shown, the panel further includes a fixing bracket 104 disposed on the inner side of the panel, and the driving unit is mounted on the panel through the fixing bracket 104 .

[0042] In the technical solution of the present application, the fixing brackets 104 can be respectively provided at both ends of the air inlet 106 for mounting the drive unit and the connecting rod mechanism. The fixing brackets 104 can be plate-shaped, and the plate-shaped surface can be used as the mounting area for mounting the drive unit and the connecting rod mechanism.

[0043] In order to facilitate the installation of the connecting rod mechanism, according to a preferred embodiment, as Figure 1 As shown in FIG2 , the connecting rod mechanism is mounted on the fixed bracket via a connecting rod base 112. In the technical solution of the present application, the connecting rod base 112 can be mounted on the fixed bracket 104 by means of bolts or the like, and the connecting rod base 112 can be provided with a plurality of pins for connecting rods to be hinged, thereby providing a stable mounting base for the connecting rod mechanism.

[0044] In order to stably operate the opening and closing plate movement, according to a preferred embodiment, as Figure 1As shown, there are two fixing brackets 104 , which are respectively arranged on both sides of the air inlet 106 along the horizontal direction, and the connecting rod mechanism includes two sets, which are respectively arranged on the two fixing brackets.

[0045] Through the present application, two sets of connecting rod mechanisms are respectively arranged on both sides of the air inlet 106 to connect to both ends of the opening and closing plate 102 to provide more stable support for the opening and closing plate 102, so that the opening and closing plate can move or maintain stably.

[0046] In order to make the two sets of connecting rod mechanisms move synchronously on the basis of easy assembly, according to a preferred embodiment, as Figure 1 As shown in FIG3 , the driving mechanism includes a synchronization rod 113 , the driving unit is provided on one of the fixed brackets 104 , one end of the synchronization rod 113 is connected to the driving unit, and the other end is connected to a connecting rod mechanism installed on another fixed bracket.

[0047] In the technical solution of the present application, the synchronization rod 113 can be in any suitable form, for example, the synchronization rod 113 can be a round rod, a square rod, or a hollow tube. The drive unit can be mounted on the fixed bracket 104 on one side and directly connected to one set of linkage mechanisms, and also connected to the synchronization rod 113, and indirectly drives another set of linkage mechanisms through the synchronization rod 113, thereby achieving the effect of synchronized movement.

[0048] According to a preferred embodiment, Figures 1 to 3 As shown:

[0049] The driving unit can be a motor 110, which is mounted on the fixed bracket 104. In order to enable the opening and closing plate 102 to move smoothly, the rotation speed of the rotating shaft of the motor 110 is not higher than 3m / s. The connecting rod mechanism can drive the rod 111, the first connecting rod 114, the second connecting rod 115, the third connecting rod 116 and the opening and closing plate connecting rod 117. The connecting rod base 112 can have two rotating shafts, and the second connecting rod 115 and the third connecting rod 116 are respectively connected to the two rotating shafts, so that the second connecting rod and the third connecting rod are rotatably mounted on the connecting rod base. The opening and closing plate connecting rod 117 is rotatably connected to the second connecting rod 115 and the third connecting rod 116, so that the movement of the opening and closing plate connecting rod 117 is restricted by controlling the movement of the second connecting rod 115. The second connecting rod 115 is connected to the driving rod 111 through the first connecting rod 114, and the other end of the opening and closing plate connecting rod 117 is connected to the back of the opening and closing plate. The motor 110 controls the rotation of the driving rod 111 to drive the first connecting rod 114 to move, thereby linking the second connecting rod 115 and the third connecting rod 116, so that the opening and closing plate connecting rod 117 moves under the drive of the second connecting rod 115 and the third connecting rod 116, thereby realizing the conversion of the opening and closing plate 102 between the open state and the closed state. It also includes a synchronization rod 113 connected to the motor 110, and the other end of the synchronization rod 113 can be connected to the driving rod 111 in the connecting rod mechanism set in the left fixed bracket 104, so as to achieve the effect of one motor 110 synchronously controlling two sets of connecting rod mechanisms, so that the opening and closing plate 102 can be stably opened and closed. The specific movement process of the opening and closing plate 102 and the connecting rod mechanism can be found in Figures 3 to 5 shown.

[0050] Since the panel 101 is tilted when in use, in order to prevent oil droplets from dripping from the upper edge of the air inlet 106 to other areas such as the table below, according to a preferred embodiment, Figure 1 、 Figure 6 and Figure 7 As shown, it also includes an oil guide strip 103, which is connected to the connecting rod mechanism so that when the opening and closing plate 102 is in the open state, the oil guide strip 103 abuts against the upper edge of the air inlet 106, so that its edge exceeds the lower edge of the air inlet 106 in the horizontal direction, and when the opening and closing plate 102 is in the closed state, the oil guide strip 103 is placed at the rear of the panel 101 and above the air inlet 106.

[0051] In the technical solution of this application, Figure 1As shown, the oil guide strip 103 can be in the shape of a long strip, and its length matches the length of the air inlet 106, wherein the oil guide strip 103 can be bent at both ends as a part connected to the panel 101, and the panel 101 can have a linkage bracket 121 at the upper edge of the air inlet 106 to correspond to the bent part of the oil guide strip 103, so that the oil guide strip 103 can be rotatably installed on the linkage bracket 121, and the linkage mechanism can also include a linkage link 120, one end of the linkage link 120 can be rotatably connected to the second link 115, and the other end can be rotatably connected to the bent part of the oil guide strip 103, so that during the movement of the linkage mechanism, the oil guide strip 103 can be linked to the opening and closing plate 102 through the linkage link 120 to achieve the following effects: Figure 6 As shown, when the opening and closing plate 102 is in the closed state, the oil guide strip 103 is on the back of the panel 101 and above the air inlet 106; Figure 7 As shown, when the opening and closing plate is in the open state, the oil guide strip 103 flips downward and abuts against the upper edge of the air inlet 106, and the oil guide strip 103 extends toward the inside of the air inlet 106, thereby forming a path for guiding the oil droplets to flow from the upper edge of the air inlet to the inside of the range hood. Under the action of the fan, negative pressure is formed inside the range hood, which can guide the oil droplets flowing through the air inlet 106 into the back of the panel 101 through the oil guide strip 103, and finally drip onto the panel below the air inlet 106, and then be guided to the component for collecting oil droplets through the panel 101.

[0052] Through the present application, when the oil droplets slide down the panel 101 and pass through the upper edge of the air inlet 106, the oil guide strip 103 forms a structure that can drain the oil droplets, so that the oil droplets can flow along the lower surface of the oil guide strip 103 under the action of its surface tension until they flow to the edge of the oil guide strip 103 and then drip onto the panel 101 located in the area below the air inlet 106, thereby preventing the oil droplets from dripping from the upper edge of the air inlet 106 to other undesirable areas such as the stove.

[0053] In order to make the oil droplets flow in more smoothly, according to a preferred embodiment, as Figure 1 、 Figures 5 to 7 As shown, when the opening and closing plate is in the open state, the oil guide strip 103 extends obliquely toward the inside of the air inlet 106. In the technical solution of this application, as shown in FIG. Figure 1As shown, the oil guide strip 103 may have a bent plate-like portion that serves as a flow path for guiding the flow of oil droplets. The edge of the bent portion may abut against the upper edge of the air inlet 106. When the oil guide strip 103 abuts against the air inlet 106, the plate-like portion may extend downwardly and tilted to the rear of the air inlet 106. The tilted plate-like portion may better guide the flow of oil droplets. Furthermore, to ensure that the oil droplets can flow smoothly from the upper edge of the air inlet 106 to the oil guide strip 103, the oil guide strip 103 may be flush with the surface of the panel 101 at the air inlet 106.

[0054] In order to prevent the oil smoke from entering through the gap between the oil guide strip 103 and the panel 101, according to a preferred embodiment, Figure 1 as well as Figures 3 to 5 As shown, the oil guide strip 103 is provided with a seal to seal the gap between the oil guide strip 103 and the panel 101 when the oil guide strip 103 abuts against the upper edge of the air inlet 106 .

[0055] In the technical solution of the present application, the sealing member can be a sealing strip 105 made of a flexible material such as sponge or foam, one side of which can be fixed to the oil guide strip 103 by gluing, so that when the oil guide strip 103 abuts against the panel 101, the sealing strip 105 can seal the gap therebetween, thereby preventing oil smoke from entering through the gap.

[0056] Second, as Figures 6 to 9 As shown, the present application also provides a range hood including the above panel assembly. The specific structure of the panel assembly is referred to the above embodiments. Since the present range hood adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The range hood can include a fume hood 200, wherein the panel 101 can serve as a part of the fume hood 200, and a detachable oil collection box 201 can be provided at the bottom of the panel 101.

[0057] According to the present application, when the range hood is started, the opening and closing plate 102 is driven by the driving mechanism to flip toward the rear and lower part of the panel 101. At this time, the air inlet 106 is opened, and the fan of the range hood creates a negative pressure inside the range hood. The oil smoke can enter the range hood through the air inlet 106 and then be discharged to the outside through the air duct. Figure 7 As shown, since the flow path of oil smoke inside the range hood is generally from bottom to top after entering the air inlet 106, and the opening and closing plate 102 is located below the air inlet 106 when in the open state, the oil smoke channel is avoided, greatly reducing the problem of oil smoke adhering to the surface of the opening and closing plate 102.

[0058] The actual operation process is as follows: Figure 6 and Figure 8As shown, when the range hood is in standby mode, the opening and closing plate 102 closes the air inlet 106 to isolate the interior of the range hood from the external environment, and the surface of the opening and closing plate 102 can be flush with the surface of the panel 101.

[0059] like Figure 7 and 9 As shown, when the range hood is started, the opening and closing plate 102 is driven by the hand-driven mechanism to flip downward inside the range hood, thereby opening the air inlet 106. The oil smoke is sucked in through the air inlet 106 and flows upward, and is finally discharged outdoors.
