[0002] With the improvement of people's life quality, the requirement of kitchen cooking environment is also increasing, and the range hood has become one of the indispensable kitchen household appliances in modern family. The range hood is driven by the motor to rotate the impeller at high speed, and forms a negative pressure area near the smoke collecting cavity, which sucks the oil fume into the body and discharges it outside.

[0003] The range hood mostly includes a shell, a flap and an oil cup, a part of the shell is enclosed to form a smoke collecting cavity with an air inlet, the oil cup is arranged at the bottom rear end of the smoke collecting cavity, the flap is rotationally connected to the shell, and the flap is opened to facilitate the suction of oil fume. The flap not only can guide the oil fume, but also can avoid the problem of oil fume escaping.

[0004] However, after the range hood works for a long time, oil stains will be attached to the inside of the range hood. Due to the vibration generated during the use of the range hood, and the range hood cannot be completely horizontal, part of the oil stains attached to the inside of the range hood will flow to the side wall of the smoke collecting cavity, and due to the gravity, it will continue to flow down along the side wall of the smoke collecting cavity to the both sides of the flap, and be attached to the flap, thereby flowing to the lower edge of the flap between the gap between the flap and the side wall, causing the risk of oil dripping.

[0039] In the following description, numerous specific details are provided for a thorough understanding of the present application. One of ordinary skill in the art will recognize, however, that the application can be practiced without one or more of these specific details. In other instances, well-known structures and processes have not been described in order not to obscure the application.

[0040] In order to thoroughly understand the embodiments of the present application, detailed structures will be presented in the following description. Obviously, the implementation of the embodiments of the present application is not limited to the special details familiar to those skilled in the art. The preferred embodiments of the present application are described in detail as follows, however, in addition to these detailed descriptions, the present application can have other embodiments.

[0041] The embodiments of the present application provide an oil guide assembly. The oil guide assembly provided by the present application can be applied to a range hood. Hereinafter, a kind of oil guide assembly according to the embodiments of the present application will be introduced in detail with reference to the drawings.

[0042] In combination with reference to Figures 1 to 9The oil guide assembly 10 may include a front shell 101, a panel 110, a side shell 102 and a flap 120. The front shell 101, the panel 110 and the side shell 102 may be enclosed to form a smoke collecting chamber 130 having an air inlet (not shown in the figure). A fixed lining 140 may be provided above the air inlet in the smoke collecting chamber 130. The flap 120 may be rotatably connected to the panel 110. The fixed lining 140 may have an avoidance hole 141. Since the flap 120 is rotatably connected to the panel 110 through a connecting rod 190, the avoidance hole 141 is mainly used to avoid the connecting rod 190 when the flap 120 rotates, so as to avoid interference with the connecting rod 190. The fixed lining 140 may have an end section 142 located between the avoidance hole 141 and the side shell 102. A first oil guide member 150 and a second oil guide member 160 may be provided on the two opposite surfaces of the end section 142, respectively. The first oil guide member 150 may define a first oil guide path (it should be understood that the first path is to allow the oil to flow along the first oil guide path). Figure 2 and Figure 4 The second oil guide member 160 may define a second oil guide path (it should be understood that the second path is to allow the oil to flow along the oil path). Figure 4 The second oil guiding path and the first oil guiding path may be connected via the avoidance hole 141 .

[0043] The oil guide assembly 10 of the present invention is configured by respectively arranging a first oil guide member 150 and a second oil guide member 160 on two opposite surfaces of the end section 142 of the fixed liner 140. The first oil guide member 150 defines a first oil guide path, and the second oil guide member 160 defines a second oil guide path. The second oil guide path is connected to the first oil guide path through the avoidance hole 141. When applied to the range hood 1, the oil inside the smoke collecting chamber 130 can flow through the first oil guide path through the avoidance hole 141 to the second oil guide member 160, and then flow to the oil box 20 below through the second oil guide path, effectively avoiding the problem of oil dripping caused by the oil flowing along the fixed liner 140 to both sides of the flap 120.

[0044] In some embodiments, the oil guide assembly 10 may further include a connecting rod 190. One end of the connecting rod 190 may be disposed on the panel 110, and the other end may be disposed on the flap 120. The flap 120 may be rotatable relative to the panel 110 via the connecting rod 190, thereby controlling the opening and closing of the air inlet via the flap 120. One end of the connecting rod 190 disposed on the panel 110 may pass through the avoidance hole 141. In this way, interference between the connecting rod 190 and the fixed lining plate 140 during the rotation of the flap 120 relative to the panel 110 may be avoided. Specifically, the connecting rod 190 may be hinged to the panel 110 at one end, and fixedly connected to the flap 120 at the other end.

[0045] See alsoFigures 1 to 8 The fixed lining plate 140 can include a side plate body 143 and a top plate body 144. The side plate body 143 can be attached to the face plate 110. The top plate body 144 can be connected to the upper end of the side plate body 143. The avoiding hole 141 can be arranged on the top plate body 144. The first oil guide 150 can have a first end 151, a second end 152 and a first connecting edge 153. The first end 151 can abut against the top plate body 144. The second end 152 can abut against the side shell 102. The first connecting edge 153 can be located between the first end 151 and the second end 152 and abut against the face plate 110. In this way, gaps are avoided between the first oil guide 150 and the fixed lining plate 140 and between the first oil guide 150 and the side shell 102, so that the oil stains flowing to both sides of the turning plate 120 are blocked by the first oil guide 150 and flow along the first oil guide path to the avoiding hole 141, thereby avoiding the problem of oil stains flowing along the fixed lining plate 140 to both sides of the turning plate 120 to cause oil dripping; and by attaching the side plate body 143 to the face plate 110, the fixed lining plate 140 is facilitated to be installed.

[0046] Understandably, the end section 142 can be formed by the part of the top plate body 144 located between the avoiding hole 141 and the side shell 102. In this way, the structure is simple and the fixed lining plate 140 is facilitated to be processed.

[0047] The fixed lining plate 140 can be formed by bending a sheet metal part. The side plate body 143 and the top plate body 144 can also be connected by welding or the like. The side plate body 143 can be attached to the face plate 110 by screw connection, gluing or the like. The first end 151 can abut against the top plate body 144 by gluing. By gluing the first end 151 to the top plate body 144, the problem of oil stains overflowing from the joint due to the existence of gaps in the joint is avoided, and the installation is facilitated. Specifically, the first end 151 can abut against the top plate body 144 by glass glue. Further, the second end 152 can also abut against the side shell 102 by gluing, and the first connecting edge 153 can also abut against the face plate 110 by gluing. Glass glue has good adhesion and corrosion resistance. Of course, the first end 151, the second end 152 and the first connecting edge 153 can also be bonded by other glues, and can also be abutted by other connection methods.

[0048] For a better understanding of the present application, reference will be made to the following drawings in combination with the detailed description of the application: Figure 1 and Figure 2The first oil guide 150 can be gradually inclined upward and outward from the first end 151 to the second end 152. In this way, when applied to the range hood 1, the first oil guide 150 can effectively guide the oil stains to the avoidance hole 141, so that the oil stains flow to the oil box 20 below. Understandably, the first oil guide 150 should be at an angle with the side shell 102 to avoid the problem that the first oil guide 150 loses the guiding effect on the oil stains due to being parallel to the side shell 102.

[0049] With reference to Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7 , the panel 110 can be fixedly connected to the front shell 101 through the fixing plate 170. The fixing plate 170 can have a lower edge 171. The second end 152 can be below the lower edge 171. In this way, not only is it convenient to install the panel 110, ensuring the firmness of the connection between the panel 110 and the front shell 101, but it also effectively ensures that the oil stains flowing down from the side shell 102 can all be guided by the first oil guide 150 to the avoidance hole 141, avoiding the problem of oil dripping to the two sides of the flap 120. The fixing plate 170 can connect the panel 110 to the front shell 101 through screws, bolts, etc. fasteners. Of course, the fixing plate 170 can also connect the panel 110 to the front shell 101 through other means.

[0050] With reference to Figures 1 to 4 , the first oil guide 150 can form a lower edge 154 at the first end 151. The width (such as the width W2 in Figure 8 ) of the lower edge 154 can be no less than the width (such as the width W1 in Figure 2 ) of the top plate body 144. In this way, the problem of oil dripping to the two sides of the flap 120 along the fixed lining plate 140 is effectively avoided. In some embodiments, the width of the lower edge 154 is equal to the width of the top plate body 144, effectively avoiding the flow of oil stains along the fixed lining plate 140 to the two sides of the flap 120 while saving materials.

[0051] Again with reference to Figures 1 to 4 , the first oil guide 150 can form an upper edge 155 at the second end 152. The projection of the upper edge 155 towards the top plate body 144 can completely cover the lower edge 154 in the width direction of the top plate body 144. In this way, the problem of oil dripping to the two sides of the flap 120 along the fixed lining plate 140 is effectively avoided.

[0052] With reference to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8The first oil guide 150 can be bent to extend a portion 156 from the first end 151 towards the side housing 102. The portion 156 can be in contact with the top plate body 144. In this way, not only the firmness of the connection between the first oil guide 150 and the top plate body 144 is ensured, but also the gap between the first oil guide 150 and the top plate body 144 is avoided, and the problem of oil flowing from the gap along the fixed lining plate 140 to both sides of the turning plate 120 is avoided.

[0053] In some embodiments, referring to Figure 8 The first oil guide 150 can be bent to extend a portion 157 from the first connecting edge 153 towards the top plate body 144. The portion 157 can be in contact with the panel 110. In this way, the firmness of the connection between the first oil guide 150 and the top plate body 144 is ensured, and the first oil guide 150 is facilitated to be installed. Further, an end of the portion 156 close to the first connecting edge 153 can be in contact with an end of the portion 157 close to the first end 151, and the structural strength of the first oil guide 150 is improved.

[0054] Specifically, the portion 156 and the portion 157 can be formed by bending the first oil guide 150, which is convenient for processing. Of course, the portion 156 and the portion 157 can also be connected to the first end 151 and the first connecting edge 153 by welding or the like.

[0055] In combination with referring to Figures 1 to 6 The avoiding hole 141 can have a hole side wall 1411. The portion 156 can have an inner side end 1561 away from the side housing 102. In the length direction of the top plate body 144, the first distance L1 between the hole side wall 1411 and the inner side end 1561 can be 0mm≤L1≤5mm. For example, the first distance L1 can be 0mm, 2.5mm, 5mm, etc. The first distance L1 in this range ensures that the oil flowing down the first oil guide 150 can be completely guided to the avoiding hole 141. In an embodiment of the present application, the first distance L1 is 0mm, which effectively ensures that the oil flowing down the first oil guide 150 can be completely guided to the avoiding hole 141.

[0056] In combination with referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 9The second oil guide member 160 may have a third end 161, a fourth end 162, and a second connecting edge 163. The third end 161 may abut the top plate 144. The fourth end 162 may be spaced apart from the top plate 144. The second connecting edge 163 may be located between the third and fourth ends 161, 162 and abut the side plate 143. In this manner, when used in the range hood 1, gaps are prevented from forming between the second oil guide member 160 and the top plate 144, or between the second oil guide member 160 and the top plate 144. Oil smoke flowing toward the sides of the flap 120 is blocked by the second oil guide member 160 and flows downward along the second oil guide path, thereby preventing oil from flowing through the gaps to the sides of the flap 120 and causing oil dripping. Specifically, the third end 161 may abut the top plate 144 using glass glue. Furthermore, the second connecting edge 163 may also abut the side plate 143 by gluing. Glass glue has good adhesion and corrosion resistance. Of course, the third end 161 and the second connecting edge 163 can also be bonded by other glues, or abutted by other connecting methods.

[0057] In some embodiments, the second oil guide member 160 may be recessed with an oil guide hole 165 extending from the fourth end 162 toward the third end 161. This ensures the oil-guiding function of the second oil guide member 160 while saving material. Furthermore, the second oil guide member 160 may be formed with a connecting portion 164 extending from the second connecting edge 163 toward the side housing 102. Of course, the connecting portion 164 may also be connected to the second connecting edge 163 by welding, gluing, or other methods. The connecting portion 164 may be attached to the side panel 143. Specifically, the connecting portion 164 may be bonded to the side panel 143 using glass glue. Of course, the connecting portion 164 may also be attached to the side panel 143 using screws or bolts. This facilitates installation of the second oil guide member 160 while enhancing the secure connection between the second oil guide member 160 and the fixed liner 140.

[0058] See also Figures 1 to 6 The avoidance hole 141 may have a hole sidewall 1411. The extension portion 156 may have an outer end 1562 away from the avoidance hole 141. In the length direction of the top plate body 144, the third end 161 may be located between the outer end 1562 and the side shell 102. In this way, when applied to the range hood 1, the third end 161 can guide the oil that flows down from the first oil guide member 150 but is not introduced into the avoidance hole 141 to the oil box 20 below, effectively avoiding the problem of oil dripping due to the oil flowing along the fixed liner 140 to the two sides of the flap 120.

[0059] Again, refer to Figures 1 to 6The outer end 1562 can have a second distance L2 from the third end 161. The third end 161 can have a third distance L3 from the side shell 102, 20mm≤L3, 5mm≤L2≤L3. For example, the second distance L2 can be 20mm, 25mm, 27mm, etc., and the third distance L3 can be 5mm, 12mm, 19mm, etc. The second distance L2 and the third distance L3 are within the range, which effectively avoids the problem of oil stains flowing along the fixed lining plate 140 to both sides of the turnover plate 120 to cause oil dripping.

[0060] With reference to Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 9 The second oil guide 160 can form a connecting edge 1611 at the third end 161. The width (such as the width W3 in Figure 9 ) of the connecting edge 1611 can be no less than the width (such as the width W1 in Figure 2 ) of the top plate body 144. In this way, the problem of oil stains flowing along the fixed lining plate 140 to both sides of the turnover plate 120 to cause oil dripping is effectively avoided. In some embodiments, the width of the connecting edge 1611 is equal to the width of the top plate body 144, which effectively avoids the problem of oil stains flowing along the fixed lining plate 140 to both sides of the turnover plate 120 while saving material.

[0061] With reference to Figures 1 to 7 The oil guide assembly 10 can further include a rear shell 103. The rear shell 103 can be connected with a deflector 180 extending into the smoke collecting cavity 130. The fourth end 162 can have an oil guide low point 1621 away from the panel 110. The vertical downward projection of the oil guide low point 1621 can fall into the deflector 180. In this way, when applied to the extractor hood 1, the deflector 180 not only can guide the wind entering the smoke collecting cavity 130 through the air inlet, but also can guide the oil stains falling on the deflector 180 to the oil box 20 below. The vertical downward projection of the oil guide low point 1621 falls into the deflector 180, avoiding the risk of oil stains falling from the second oil guide 160 falling outside the deflector 180 to cause oil dripping. The projection of the deflector 180 towards the oil box 20 can be completely located in the oil box 20, effectively ensuring that the oil stains falling from the deflector 180 can fall into the oil box 20, avoiding the risk of oil dripping.

[0062] Again with reference to Figure 1 and Figure 7, the air deflector 180 can have an air deflector edge 181 away from the rear shell 103. In a direction perpendicular to the rear shell 103, the fourth distance L4 can be between the oil deflector low point 1621 and the air deflector edge 181, 5mm≤L4. For example, the fourth distance L4 can be 5mm, 8mm, 17mm, etc. The fourth distance L4 is within this range, effectively ensuring that the oil stains dripping from the second oil guide 160 can fall onto the air deflector 180, avoiding the risk of oil dripping. In some embodiments applied to the extractor hood 1, the air deflector 180 can have an air deflector upper edge 182 away from the oil box 20. In a direction perpendicular to the rear shell 103, the fourth distance L4 is equal to half the distance between the air deflector edge 181 and the air deflector upper edge 182, effectively ensuring that the oil stains dripping from the second oil guide 160 can fall onto the air deflector 180, avoiding the risk of oil dripping.

[0063] With reference to Figures 1 to 4 , the fixed lining plate 140 can further include an end plate body 145 connected to the end of the side plate body 143 and the end of the top plate body 144, respectively. The end plate body 145 can have a lower side 1451 opposite the top plate body 144. The lower side 1451 and a plane perpendicular to the rear shell 103 can have an included angle β, β≥20°. For example, the included angle β can be 20°, 23°, 30°, etc. The included angle β is within this range, when applied to the extractor hood 1, the oil stains flowing along the fixed lining plate 140 to both sides of the flap 120 that are not guided by the second oil guide 160 to the lower side can flow down along the lower side 1451 of the end plate body 145, thereby being guided by the air deflector 180 to the oil box 20, effectively avoiding the problem of oil dripping caused by the oil stains flowing along the fixed lining plate 140 to both sides of the flap 120.

[0064] With reference to Figures 1 to 4 , the lower side 1451 can have a side low point 1451a away from the panel 110. The vertical downward projection of the side low point 1451a can fall within the air deflector 180. In this way, the oil stains dripping from the end plate body 145 fall outside the air deflector 180, avoiding the risk of oil dripping.

[0065] With reference to Figure 1 and Figure 7The air deflector 180 can have an air deflector edge 181 away from the rear shell 103. In a direction perpendicular to the rear shell 103, the fifth distance L5 can be between the side low point 1451a and the air deflector edge 181, 5mm≤L5. For example, the fifth distance L5 can be 5mm, 13mm, 22mm, etc. The fifth distance L5 in this range effectively ensures that the oil stains dripping from the end plate body 145 can fall on the air deflector 180, avoiding the risk of oil dripping. In some embodiments applied to the range hood 1, the air deflector 180 can have an air deflector upper edge 182 away from the oil box 20. In a direction perpendicular to the rear shell 103, the fifth distance L5 is equal to half the distance between the air deflector edge 181 and the air deflector upper edge 182, effectively ensuring that the oil stains dripping from the end plate body 145 can fall on the air deflector 180, avoiding the risk of oil dripping.

[0066] According to another aspect of the present application, a range hood 1 can include an oil box 20 and the oil guide assembly 10 as described above. The oil box 20 is arranged below the smoke collecting cavity 130. Since the oil guide assembly 10 as described above has the above-mentioned beneficial effects, the range hood 1 including the oil guide assembly 10 as described above also has the above-mentioned beneficial effects, which will not be repeated here.

[0067] In combination with reference to Figure 2 and Figure 4 , the flow direction of the oil stains under the guidance of the oil guide assembly 10 is described as follows: the oil stains inside the smoke collecting cavity 130, part of which flows along the side shell 102 to the first oil guide 150, flows from the second end 152 to the first oil guide 150, and then flows along the Figure 2 and Figure 4 arrows I-I shown in the figure to the avoidance hole 141, and the other part flows along the panel 110 to the first oil guide 150, and flows along the Figure 2 and Figure 4 arrows I-I shown in the figure to the avoidance hole 141. The oil stains guided to the first end 151 can flow along the avoidance hole 141 to the second oil guide 160. The oil stains flowing from the avoidance hole 141 to the second oil guide 160, part of which can flow from the third end 161 to the fourth end 162 along the Figure 4 arrows K-K shown in the figure, and then drip onto the air deflector 180, and finally be guided into the oil box 20 below, and the other part can flow along the connecting edge 1611 to the end of the second oil guide 160 away from the second connecting edge 163, and then flow along the Figure 4The arrow K-K shown flows to the oil guide low point 1621, drips from the oil guide low point 1621 to the deflector 180, and is finally guided to the oil box 20 below, which is the second oil guide path defined by the second oil guide 160. In some embodiments, the oil stains flowing from the third end 161 to the fourth end 162 along the second connecting edge 163 can flow along the side plate body 143 to the end plate body 145, flow along the lower side edge 1451 to the side edge low point 1451a, and then drip from the side edge low point 1451a to the deflector 180, and finally be guided to the oil box 20 below.
