[0047] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0048] In modern kitchens, range hoods are essential equipment for cooking, used to remove cooking fumes and ensure a clean and healthy kitchen environment.

[0049] For ease of description, we assume the user is facing the range hood. We define the side of the range hood facing the user as the front side, the side of the range hood facing away from the user as the back side, the left and right directions of the range hood as the length direction, and the height direction of the range hood as the vertical direction.

[0050] Figure 1 as well as Figure 2 A schematic diagram of the structure of a range hood according to one or more embodiments of this application is shown. For clarity, Figure 2 The backplate of the rack was omitted, combined with Figure 1 as well as Figure 2 The range hood includes a frame 100 and a fan assembly 200 disposed inside the frame 100. The frame 100 of the range hood has a vent 101 at the bottom and an exhaust vent 102 at the top. During the operation of the range hood, the fan inside the fan assembly 200 is driven to draw the cooking fumes into the fan assembly 200 through the vent and exhaust them from the exhaust vent 102.

[0051] In related technologies, range hoods are typically wall-mounted. A mounting hole is located on the back of the range hood, and a bracket on the wall mates with this hole. The range hood is suspended from the wall through the connection between the mounting hole and the bracket. During operation, the airflow inside the range hood can easily overflow from this mounting hole 105, forming oil droplets. These oil droplets drip down the back of the range hood onto the cooktop, causing adverse effects and impacting the user experience.

[0052] Based on the above-mentioned technical problems, this application provides a rack designed to at least prevent airflow from overflowing from the hanging holes on the back of the range hood and forming oil droplets, which then drip down the back of the range hood onto the stovetop, thereby improving the user experience.

[0053] Figure 3 It shows Figure 1 A top-down view diagram. Figure 4 It shows Figure 3 A schematic diagram of the AA cross-section. Combined with... Figure 3 as well as Figure 4 The frame 100 provided in this application is applied to a range hood. The frame 100 includes a back plate 103 and a first oil guide plate 104. The back plate 103 is provided with a hanging hole 105. The first oil guide plate 104 has a first side and a second side. The first side of the first oil guide plate 104 is connected to the inner side of the back plate 103 and is located below the hanging hole 105. The second side of the first oil guide plate 104 extends into the frame 100.

[0054] The frame 100 provided in this application has a first side of the first oil guide plate 104 connected to the inner side of the back plate 103 of the frame 100, and the first side of the first oil guide plate 104 is positioned below the hanging hole 105. The second side of the first oil guide plate 104 extends into the frame 100, which can block the airflow from moving upward during the operation of the range hood to a certain extent, thereby preventing the airflow from moving upward to overflow into the hanging hole 105 of the back plate 103 and forming oil droplets, so as to avoid oil droplets dripping down the back of the range hood onto the stove, thus improving the user experience.

[0055] Figure 5 A schematic diagram of the assembly of the back plate and the bracket is shown. Figure 6 It shows Figure 5 A schematic diagram of the explosion. Combined with... Figure 5 as well as Figure 6 The frame 100 of this application is generally a box-shaped structure. The back plate 103 is set on the back of the frame 100. The back plate 103 is provided with at least two hanging holes 105 at intervals along the horizontal direction. The support plate 107 is provided on the front side of the bracket 106. The support plate 107 and the hanging holes 105 are provided one-to-one. The support plate 107 is inserted into the corresponding hanging hole 105. The bracket 106 is provided with multiple connecting holes 108 so as to assemble the bracket 106 to the user's wall by bolts or other connecting parts 115. The back plate 103 of the frame 100 is suspended on the support plate 107 of the bracket 106 so as to suspend the range hood on the user's wall. This is the prior art, and the applicant will not elaborate on it.

[0056] Figure 7 A schematic diagram of the first oil guide plate is shown. Figure 8 A schematic diagram of the assembly of the first oil guide plate and the back plate is shown. According to one embodiment of this application, the first side of the first oil guide plate 104 abuts against the inner side (front side) of the back plate 103 and is positioned below the hanging hole 105 to prevent the airflow generated when the range hood is working from escaping through the gap between the first side of the first oil guide plate 104 and the inner side of the back plate 103.

[0057] According to one embodiment of this application, the distance between the first side of the first oil guide plate 104 and the bottom of the hanging hole 105 can be 5-10mm to ensure that there is enough space inside the frame 100 to accommodate the movement of airflow.

[0058] Combination Figure 7 as well as Figure 8 According to one embodiment of this application, a first flange 109 is connected to the first side of the first oil guide plate 104. The first flange 109 and the first oil guide plate 104 are integrally formed. The first flange 109 extends downward from the first oil guide plate 104 and is attached to the inner side of the back plate 103 to ensure that there is no gap between the first side of the first oil guide plate 104 and the inner side of the back plate 103, thereby preventing the airflow generated when the range hood is working from escaping through the gap between the first side of the first oil guide plate 104 and the inner side of the back plate 103. In another embodiment, the first flange 109 may also extend upward from the first oil guide plate 104, and this application does not limit this.

[0059] Figure 9 It shows Figure 8 The explosion diagram, combined with Figures 7-9 According to one embodiment of this application, two or more support members 110 are provided at intervals on the inner side of the back plate 103. The first flange 109 on the first side of the first oil guide plate 104 can be supported on the two or more support members 110 to support and position the first side of the first oil guide plate 104. In specific implementation, the support member 110 can be an L-shaped plate structure, which is integrally formed on the inner side of the back plate 103.

[0060] According to one embodiment of this application, the first oil guide plate 104 is detachably mounted within the frame 100. Figure 10 A schematic diagram of the assembly of the first guide plate with the frame 100 is shown. Figure 11 It shows Figure 10 An enlarged view of point A. For clarity, Figure 10 The backplate 103 of the rack 100 has been omitted. (Combined) Figure 10 as well as Figure 11In a specific implementation, the frame 100 also includes two side plates 112, which are connected to each other on both sides of the back plate 103 along its length. The two side plates 112 and the back plate 103 form a U-shaped structure. A first oil guide plate 104 is fitted between the two side plates 112, and the length dimension of the first oil guide plate 104 is slightly smaller than the dimension between the two side plates 112. A second flange 111 is connected to the side of the first oil guide plate 104 facing the side plate 112. The second flange 111 can be integrally formed with the first oil guide plate 104. The second flange 111 extends downward toward the first oil guide plate 104 and fits against the inner side of the side plate 112 on the same side. The second flange 111 and the side plate 112 on the same side can be connected by screws or other components to fix the first oil guide plate 104 inside the frame 100. The second flange 111 along the length of the first oil guide plate 104 is attached to the inner side of the side plate 112 on the same side, thus ensuring no gaps between the two sides of the first oil guide plate 104 along its length and the inner sides of the two side plates 112. This prevents the airflow generated during the operation of the range hood from escaping through the gaps between the sides of the first oil guide plate 104 along its length and the inner sides of the two side plates 112. In another embodiment, the second flange 111 may also extend upwards from the first oil guide plate 104; this application does not limit this.

[0061] Figure 12 It shows Figure 1 Another structural diagram from a different perspective, for clarity. Figure 12 The backplate 103 of the rack 100 has been omitted. (Combined) Figure 12 According to one embodiment of this application, the second side of the first oil guide plate 104 is higher than the first side, that is, the front side of the first oil guide plate 104 is higher than the back side of the first oil guide plate 104, and the first oil guide plate 104 is inclined towards the front side of the frame 100 to ensure the internal space of the frame 100. In specific implementation, the slope of the first oil guide plate 104 can be 20-30°.

[0062] Combination Figure 12 According to one embodiment of this application, a range hood includes a fan assembly 200 disposed within a frame 100. The fan assembly 200 includes a fan housing 201, which has an air inlet 202 facing the back of the frame 100 (back plate 103). During operation of the range hood, the fan assembly 200 operates to generate airflow within the frame 100. The airflow is introduced into the fan housing 201 through the air inlet 202 and discharged from the exhaust port 102 at the top of the fan housing 201. The second side (front side) of the first oil guide plate 104 is disposed above the air inlet 202, thereby preventing airflow from escaping upwards to the top of the first oil guide plate 104 and forming oil droplets on its top surface.

[0063] Combined with the diagram Figure 11 as well as Figure 12 According to one embodiment of this application, the frame 100 further includes a top plate 113, which is placed above the fan housing 201. The top plate 113 is connected to the top of the back plate 103 and the two side plates 112. The second side (front side) of the first oil guide plate 104 abuts against the bottom of the top plate 113 to prevent the airflow generated when the range hood is working from escaping through the gap between the second side of the first oil guide plate 104 and the bottom of the top plate 113.

[0064] Combined with the diagram Figure 11 as well as Figure 12 According to one embodiment of this application, a third flange 114 is provided on the second side (front side) of the first oil guide plate 104. The third flange 114 bends upward toward the first oil guide plate 104 and is generally horizontally arranged. The third flange 114 abuts against the bottom of the top plate 113 to ensure that there is no gap between the second side of the first oil guide plate 104 and the bottom of the top plate 113, thereby preventing the airflow generated during the operation of the range hood from escaping through the gap between the second side of the first oil guide plate 104 and the bottom of the top plate 113. In addition, bolt holes may also be provided on the third flange 114 to connect the third flange 114 to the top plate 113 by bolts, thereby improving the reliability of the first oil guide plate 104 in the frame 100 assembly. In specific implementation, the distance between the second side of the first oil guide plate 104 and the top of the fan housing 201 is between 10-15 mm.

[0065] According to one embodiment of this application, the flanges around the first oil guide plate 104 can be integrally formed with the first oil guide plate 104 to facilitate the manufacturing, transportation and assembly of the first oil guide plate 104.

[0066] According to another embodiment of this application, the first oil guide plate 104 may also be integrally formed on the back of the frame 100, or connected to the back of the frame 100 by means of snap-fit ​​or the like. This application does not limit this.

[0067] Based on the same design concept, this application also provides a range hood, which includes the aforementioned frame 100. The frame 100, through the setting of the first oil guide plate 104, can prevent the airflow generated during the operation of the range hood from overflowing through the hanging holes 105 of the back plate 103 of the frame 100 and dripping onto the stove. Furthermore, by adding flanges around the first oil guide plate 104, it is ensured that the airflow will not overflow from the gaps between the first oil guide plate 104 and the frame 100, thus preventing oil droplets from forming on the top surface of the first oil guide plate 104, thereby improving the user experience and having good practicality.

[0068] In related technologies, the air outlet of the fan assembly 200 of the range hood extends through a pipe to the exhaust port 102 provided on the top plate 113 of the frame 100. The exhaust port 102 is connected to the exhaust pipe through an adapter 116 so that the airflow generated during the operation of the range hood can be discharged from the exhaust pipe. However, the exhaust port 102 of the range hood and the adapter 116 are often fixedly connected with screws, which makes the exhaust port 102 on the top plate 113 of the frame 100 prone to deformation. This results in a poor sealing effect between the exhaust port 102 of the frame 100 and the exhaust pipe, and oil leakage is likely to occur at the exhaust port 102 of the frame 100.

[0069] Based on the above-mentioned technical problems, this application provides a rack 100, which aims to at least prevent the exhaust port 102 of the top plate 113 of the rack 100 from being easily deformed, resulting in a poor sealing effect between the exhaust port 102 of the rack 100 and the exhaust pipe, and the exhaust port 102 of the rack 100 from easily leaking oil.

[0070] Figure 13 A schematic diagram of the rack structure is shown. Figure 14 It shows Figure 13 An explosion diagram. Figure 15 It shows Figure 13 A structural diagram of the adapter in the diagram. For clarity, Figure 13 as well as Figure 14 The backplate 103 of the rack 100 has been omitted. (Combined) Figures 13-15 The rack 100 provided in this application includes a top plate 113, a connector 115, and an adapter 116.

[0071] The rack 100 provided in this application has an exhaust vent 102 on its top plate 113. A connector 115 is connected to the edge of the exhaust vent 102 on the top plate 113, and an adapter 116 is connected to it. That is, the adapter 116 is connected to the top of the top plate 113 of the rack 100 via the connector 115, which strengthens the edge of the exhaust vent 102 on the top plate 113 and prevents deformation of the exhaust vent 102 on the top plate 113 to a certain extent. Furthermore, because the adapter... The sealing part 118 at the bottom of the connector 116 is interference-fitted into the vent 101 of the top plate 113. Through the interaction between the top plate 113 and the connector 116, deformation of the sealing part 118 of the connector 116 and the vent 101 of the top plate 113 can be prevented, thereby improving the sealing effect between the connector 116 and the connector 115 and avoiding oil leakage caused by deformation of the connector 116 and the exhaust vent 102 of the top plate 113. It has good practicality.

[0072] Combination Figure 13 According to one embodiment of this application, a positioning recess 119 is provided on the top of the top plate 113, and an exhaust port 102 is provided at the center of the bottom wall of the positioning recess 119, so that the bottom wall of the positioning recess 119 has an edge provided on the outside of the exhaust port 102, thereby forming a support structure for supporting the connector 115, which is supported at the edge of the bottom wall of the positioning recess 119.

[0073] Combination Figure 13 According to one embodiment of this application, a plurality of first bolt holes 120 are provided at intervals at the edge of the bottom wall of the positioning recess 119 for connection with the connector 115.

An air vent 117 on the connector 115 is located at the center of the connector 115. The air vent 117 has the same shape as the exhaust vent 102. The airflow generated when the range hood is working is discharged sequentially through the exhaust vent 102 and the air vent 117. A plurality of second bolt holes 121 are spaced apart on the connector 115, and the second bolt holes 121 correspond one-to-one with the first bolt holes 120, so that the connector 115 is bolted to the edge of the bottom wall of the positioning recess 119 of the top plate 113.

[0075] According to one embodiment of this application, a gasket is provided between the bottom wall of the connector 115 and the positioning recess 119. The gasket is also a thin sheet structure in the shape of a U-shape, and its size is approximately the same as that of the positioning recess 119, so as to further strengthen the edge strength of the exhaust port 102 of the top plate 113 and prevent the edge of the exhaust port 102 of the top plate 113 from deforming.

[0076] According to one embodiment of this application, a plurality of third bolt holes 122 are also provided on the gasket at intervals. The third bolt holes 122 are provided in a one-to-one correspondence with the second bolt holes 121 and the first bolt holes 120, so that the gasket is connected to the edge of the bottom wall of the positioning recess 119 of the top plate 113 and the connector 115 by bolts.

The connecting post 130 has the aforementioned fourth bolt hole 125, which connects the fourth flange 124, the connecting member 115, the gasket, and the edge of the positioning recess 119 of the top plate 113, so as to assemble the adapter 116 at the exhaust port 102 of the top plate 113. In a specific implementation, multiple connecting posts 130 can be spaced apart on the first reinforcing member 128. In addition, the connecting hole 108 can be a blind hole structure to allow bolts to be installed from inside the frame 100.

[0081] According to one embodiment of this application, the top of the fourth flange 124 and the outer periphery of the adapter 116 are connected by a plurality of reinforcing pieces 131, and a plurality of reinforcing ribs 139 are spaced around the periphery of the adapter 116 to further enhance the structural strength of the fourth flange 124 and improve the reliability of the connection of the fourth flange 124.

[0083] To ensure the reliability of the seal between the sealing part 118 and the vent 101 of the connector 115, the interference fit between the sealing part 118 and the vent 101 of the connector 115 is 0.3-0.5mm.

[0084] According to one embodiment of this application, the sealing part 118 is connected to the bottom edge of the exhaust channel 123 to avoid the sealing part 118 affecting the airflow output, which has good practicality.

[0085] According to one embodiment of this application, the adapter 116 can be a backflow valve. When the range hood is running, the adapter 116 is opened to facilitate airflow output. When the range hood is turned off, the adapter 116 is closed to prevent airflow backflow and the generation of odors.

[0086] Based on the same design concept, this application also provides a range hood, which includes the aforementioned frame 100. The frame 100 is connected via a connector 115, and the interference fit between the adapter 116 and the connector 115 can, to a certain extent, prevent deformation at the exhaust vent 102 of the top plate 113 and deformation at the sealing part 118 of the adapter 116, thereby improving the sealing effect between the adapter 116 and the connector 115 and avoiding oil leakage caused by deformation of the adapter 116 and the exhaust vent 102 of the top plate 113. It has good practicality.

[0087] In related technologies, the internal wiring of the range hood frame 100 needs to be protected with a cable cover to ensure the performance and reliability of the electrical appliances. However, the addition of the cable cover increases the cost of the components, and the cable cover cannot completely seal the wiring harness, which poses a risk to the performance and reliability of the electrical appliances.

[0088] Based on the above-mentioned technical problems, this application provides a rack 100, which aims to seal the wiring harness to a certain extent while ensuring electrical performance and reliability, and reducing manufacturing costs.

[0089] In related technologies, the internal wiring of range hoods needs to be protected with a cable cover to ensure the performance and reliability of the appliances. However, the addition of the cable cover increases the cost of the components, and the cable cover cannot completely seal the wiring harness, which may affect the performance and reliability of the appliances.

[0090] Based on the above-mentioned technical problems, this application provides a frame 100 for a range hood, which aims to at least partially solve the problem of increased cost caused by adding a wire cover to the internal wiring of the range hood, and improve the risk of affecting the electrical performance and reliability caused by the wire cover not being able to completely seal the wire harness.
