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 commonly used appliances in modern kitchens. To improve ease of use and overall aesthetics, current range hoods on the market are usually equipped with an opening and closing panel at the air inlet. In order to avoid blocking the user's view or occupying additional operating space when the panel is open, some range hoods have optimized the movement trajectory of the opening and closing panel. The opening and closing panel is usually controlled by a drive mechanism to move inward, so that the panel is hidden inside the range hood body when it is open, which does not affect the user's observation of the cooking status and reduces the risk of collision between the panel and the user, thereby improving the user experience.

[0003] However, when the range hood with a hidden panel is in operation, the oil smoke will pass through the position where the opening and closing panel is hidden during the suction process. If the decorative surface of the opening and closing panel is exposed in the oil smoke passage, the oil smoke will easily condense and adhere to the surface of the opening and closing panel, resulting in the accumulation of oil stains, which not only affects the aesthetics of the range hood, but also increases the difficulty of cleaning.

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

[0025] In order to solve the technical problem in the prior art that the opening and closing plates of range hoods are easily attached with oil smoke, the present application provides a panel assembly for range hoods, which can achieve the effect of reducing the oil smoke adhesion on the opening and closing plates.

[0026] First, Figures 1 to 5A panel assembly provided for 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.

[0027] In the technical solution of the present application, the panel 101 is a part of the smoke collecting hood of the range hood, and is provided with an air inlet 106 for allowing the oil smoke to enter the oil smoke passage inside the range hood and then be discharged outdoors. The size of the opening and closing plate 102 matches that of the air inlet 106. In the closed state, the opening and closing plate 102 completely closes the air inlet 106, and the surface of the opening and closing plate 102 can be flush with the surface of the panel 101.

[0028] The driving mechanism includes a driving unit and a connecting rod mechanism, wherein the driving unit can be in the form of a motor, a cylinder, etc., which is not limited here, as long as it can drive the connecting rod to move. The driving unit can be installed on the inner side of the panel 101, close to the air inlet 106, and the driving unit can be one or more, which is not limited here, as long as it corresponds to the connecting rod mechanism to provide power for the connecting rod mechanism.

[0029] The connecting rod mechanism may include one or more, for example, a connecting rod mechanism may be arranged below the middle of the air inlet 106, and one end of the connecting rod mechanism is connected to the middle of the opening and closing plate 102; or, two connecting rod mechanisms may be provided, which are respectively installed on both sides of the air inlet 106, and the two connecting rod mechanisms are respectively connected to the two ends of the opening and closing plate 102. In this case, two driving units may be provided to be connected to the two connecting rod mechanisms respectively, or a driving unit may be provided below the middle of the air inlet 106, and connected to the two connecting rod mechanisms through a transmission rod, etc., which are not limited 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 adopt a multi-link form 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.

[0030] In the open state, 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, thereby further preventing the decorative surface of the opening and closing plate 102 from contacting oil smoke.

[0031] In order to facilitate the installation of the drive unit and the connecting rod mechanism, according to a preferred embodiment, Figure 1 As shown, it also includes a fixing bracket 104 arranged on the inner side of the panel, and the driving unit is installed on the panel through the fixing bracket 104.

[0032] In the technical solution of the present application, the fixing bracket 104 can be respectively arranged at both ends of the air inlet 106 for installation of the drive unit and the connecting rod mechanism. The fixing bracket 104 can be a plate-shaped structure, and its plate-shaped surface can be used as an installation area for installing the drive unit and the connecting rod mechanism.

[0033] In order to facilitate the installation of the connecting rod mechanism, according to a preferred embodiment, Figure 1 As shown in FIG. 2 , 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 installation foundation for the connecting rod mechanism.

[0034] In order to stably operate the opening and closing plate movement, according to a preferred embodiment, Figure 1 As shown, the fixing brackets 104 include two, and the two fixing brackets 104 are respectively arranged on both sides of the air inlet 106 along the horizontal direction, and the connecting rod mechanism includes two sets, and the two sets of the connecting rod mechanism are respectively arranged on the two fixing brackets.

[0035] 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.

[0036] In order to make the two sets of connecting rod mechanisms move synchronously on the basis of easy assembly, according to a preferred embodiment, Figure 1 As shown in FIG. 3 , the driving mechanism includes a synchronization rod 113 , the driving unit is arranged 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.

[0037] In the technical solution of the present application, the synchronization rod 113 can be in an appropriate form, for example, the synchronization rod 113 can be a round rod, a square rod or a hollow tube, etc. The driving unit can be installed on the fixed bracket 104 on one side and directly connected to a set of connecting rod mechanisms, and connected to the synchronization rod 113, and indirectly drive another set of connecting rod mechanisms through the synchronization rod 113, so as to achieve the effect of synchronous movement.

[0038] According to a preferred embodiment, Figures 1 to 3 As shown: The driving unit may be a motor 110, which is mounted on a fixed bracket 104, wherein the rotation speed of the rotating shaft of the motor 110 is not higher than 3 m / s in order to enable the opening and closing plate 102 to move smoothly. The connecting rod mechanism may 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 may have two rotating shafts, 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 driving rod 111 to rotate and drive the first connecting rod 114 to move, so that the second connecting rod 115 and the third connecting rod 116 are linked, and the opening and closing plate connecting rod 117 is driven by the second connecting rod 115 and the third connecting rod 116 to move, so that the opening and closing plate 102 can be switched 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 on 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 seen in Figures 3 to 5 shown.

[0039] 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 7As 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 an 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 a closed state, the oil guide strip 103 is placed at the rear of the panel 101 and above the air inlet 106.

[0040] In the technical solution of this application, Figure 1 As 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 flip, thereby achieving 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 located 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 the oil droplets through the panel 101.

[0041] Through the present application, when oil droplets slide down the panel 101 and pass over 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 their 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.

[0042] In order to make the oil droplets flow in more smoothly, according to a preferred embodiment, 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 the present application, Figure 1 As shown, the oil guide strip 103 may have a bent plate-like portion, which serves as a flow path for guiding the flow of oil droplets, and 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 can extend downwardly and tilted to the rear of the air inlet 106, and the tilted plate-like portion can better guide the flow of oil droplets. In addition, in order to allow the oil droplets to flow smoothly from the upper edge of the air inlet 106 to the oil guide strip 103, the oil guide strip 103 can be flush with the surface of the panel 101 at the air inlet 106.

[0043] 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 .

[0044] 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.

[0045] 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 refers to the above embodiment, since the range hood adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. The range hood can include a fume hood 200, wherein the panel 101 can be used 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.

[0046] 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, and the air inlet 106 is opened. The fan of the range hood forms a negative pressure inside the range hood, and 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.

[0047] The actual operation process is as follows: Figure 6 and Figure 8 As 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 .

[0048] 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, and the oil smoke is sucked in through the air inlet 106 and flows upward, and is finally discharged outdoors.
