These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0040] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0041] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0042] In addition, the terms "disposed", "connected", and "fixed" should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present disclosure can be understood according to the specific circumstances.

[0043] Unless otherwise stated, the term "plurality" means two or more.

[0044] As can be seen from the background technology, the range hood is usually equipped with power lines, control panel lines, lighting lines, exhaust fan lines and other functional lines, which need to be arranged according to certain rules to ensure safety and reliability. In the prior art, these lines are arranged inside the range hood to avoid affecting the aesthetics and safety of the range hood.

[0045] The wiring inside the range hood can be arranged by installing a wire guard or wire organizer inside the range hood. However, it is difficult to avoid passing through the inside of the flue during the wiring arrangement process, which will cause the wire guard or wire organizer to protrude from the surface of the flue after installation, occupying the space inside the flue.

[0046] The back plate of the range hood can also be directly pressed inward to form a wiring groove, and a cover plate can be set on the outside of the back plate to cover the wiring groove to protect the line. This method of pressing the wiring groove will also compress the space of the flue when passing through the area where the flue is located, affecting the flow performance of the air inside the flue.

[0047] The wire guards, wire organizers or wire troughs protruding from the inner wall of the flue reduce the width of the flue, increase the resistance in the flue, disrupt the flow of air in the flue, and affect the flow efficiency of the gas. In addition, when the air passes through these structures, eddies or turbulence will be generated, resulting in increased vibration and noise in the flue, affecting the user experience.

[0048] It can be seen from this that the layout of the lines inside the range hood will affect the air circulation in the flue.

[0049] To solve the above-mentioned problem, the present application provides a range hood rear plate and a range hood, wherein a second groove body is arranged on the first plate body of the range hood rear plate, and a first groove body is arranged on the reinforcement member connected to the first plate body, and the first groove body and the second groove body together enclose a first wiring groove. When the total width L of the first wiring groove required for wiring remains unchanged, since the second groove body extends a certain width L1 away from the flue, which is equivalent to setting part of the first wiring groove outside the flue, the width L2 (L2=L-L1) of the first groove body extending toward the flue is reduced, so that the first wiring groove will not occupy too much space in the flue, so as not to affect the flow of air in the flue, thereby solving the problem of affecting the air circulation in the flue caused by the arrangement of lines in the range hood.

[0050] Figure 1 A diagram showing the installation state of the range hood rear panel provided in an embodiment of the present application; Figure 2 A schematic diagram of the structure of the range hood rear plate provided in an embodiment of the present application; Figure 3 for Figure 2 A structural diagram of the rear panel of the central range hood from another perspective; Figure 4 for Figure 2 A cross-sectional view of the first plate and the reinforcement along AA; Figure 5 for Figure 4 Enlarged view of point B in the middle.

[0051] On the one hand, combined with Figures 1 to 5 As shown, the present application provides a range hood rear plate, which is used to be set on a side of the range hood close to the wall. The range hood rear plate includes a first plate body 100, which is used to be set on a flue side of the range hood. A reinforcement 200 is provided on the side of the first plate body 100 facing the flue, and a first groove body 310 protruding toward the flue is provided on the reinforcement 200. A second groove body 320 protruding away from the flue is provided on the first plate body 100, and the grooves of the first groove body 310 and the second groove body 320 are opposite to each other and together enclose a first wiring groove 300.

[0052] It is understandable that the range hood has different types of installation methods, such as wall-mounted or hanging, etc. Different types of installation methods need to be selected according to the environmental requirements of different kitchens. Taking a wall-mounted range hood as an example, the back plate is a structure installed on the back of the range hood, which has a certain thickness and strength. The range hood is connected to the back plate by screws or other fixings. During installation, the back plate is fixed to the wall, thereby firmly installing the range hood on the wall.

[0053] The back panel of the range hood is usually made of strong and durable materials such as metal or plastic to withstand the weight of the range hood and the forces it is subjected to during installation. There are usually multiple holes preset on the back panel for installing screws, expansion bolts or other fixings to connect other parts of the range hood. In addition, some other slots are reserved on the back panel for connecting the power cord of the range hood, exhaust ducts, etc., so as to connect the range hood to the external power supply and exhaust system.

[0054] When installing a range hood, space for wiring is usually reserved on the rear panel or other structures of the range hood in combination with specific designs and requirements to facilitate the arrangement and connection of the lines. For example, a wire management piece is installed inside the range hood, or the rear panel of the range hood is directly pressed inward to serve as a wire trough, and the lines are laid in the wire management piece or the wire trough. However, the wire management piece or the wire trough will compress the space of the flue, affecting the flow performance of the air inside the flue.

[0055] The rear plate of the range hood provided in the embodiment of the present application has a reinforcement 200 which can be used to improve the strength of the rear plate; in addition, a second groove body 320 protruding away from the flue is provided on the first plate body 100, and a first groove body 310 protruding toward the flue is provided at a position on the reinforcement 200 corresponding to the second groove body 320. The first groove body 310 and the second groove body 320 together form a first wiring groove 300. In this way, the wiring groove is formed by the cooperation of the reinforcement 200 and the rear plate. When the total width L of the first wiring groove 300 required for wiring is constant, by protruding the second groove body 320 in the direction away from the flue by a width L1, it is equivalent to arranging part of the first wiring groove 300 outside the flue, and the width L2 (L2=L-L1) of the first groove extending toward the flue is reduced, so that the first wiring groove 300 will not occupy too much space in the flue, so as not to affect the flow of air in the flue, thereby solving the problem of affecting the air circulation in the flue caused by the arrangement of lines in the range hood.

[0056] Exemplarily, the first trough body 310 and the second trough body 320 can be manufactured by a sheet metal stamping process, which has the characteristics of low processing difficulty and small error, and is easy to implement.

[0057] In some embodiments, a first entrance 330 is disposed at one end of the first wiring groove 300 in the extending direction; and at least one second entrance 340 communicating with the first wiring groove 300 is opened on the reinforcement member 200 .

[0058] Combination Figure 4 As shown, the first entrance and exit 330 is arranged on one side of the extension direction of the first wiring trough 300. By setting the first entrance and exit 330, it is convenient for the line to change its direction here, reduce the crossing and confusion of the line, and keep the line neat and orderly.

[0059] Combination Figure 3As shown, the second entrance 340 is provided on the reinforcement 200 and is located on the side of the first wiring trough 300 close to the interior of the range hood. Since the electrical system inside the range hood usually has multiple lines, such as power lines, control lines, communication lines, etc., by providing the second entrance 340, it is convenient for the lines of the electrical equipment inside the range hood to pass through or pass through the second entrance 340; and multiple second entrances 340 can also allow the lines of different equipment to enter or exit the first wiring trough 300 from different directions, so as to better organize and manage the lines; in addition, when the electrical system inside the range hood is subsequently maintained or changed, it is also convenient to adjust or add the lines.

[0060] Among them, the arrangement position of the second entrance and exit 340 is close to the two ends of the extension direction of the first wiring trough 300, so that the second entrance and exit 340 can be closer to the electrical equipment installed on both sides of the range hood to reduce the length of the exposed line. At the same time, it also avoids the location of the flue to prevent the second entrance and exit 340 from affecting the air flow in the flue.

[0061] Figure 6 for Figure 2 Exploded view of the second plate and cover. Figure 6 As shown, in some embodiments, a second plate body 400 is further included, and the second plate body 400 is connected to the side of the reinforcement 200 facing away from the first plate body 100. The second plate body 400 is used to be arranged on the fan side of the range hood, and a cover plate 500 is provided on the side of the second plate body 400 facing away from the fan; the second plate body 400 is provided with a third groove body 610 protruding toward the fan, and the cover plate 500 is provided with a fourth groove body 620 protruding away from the fan, and the grooves of the third groove body 610 and the fourth groove body 620 are opposite to each other and together enclose a second wiring groove 600, and the second wiring groove 600 is connected to the first wiring groove 300 through the first entrance and exit 330.

[0062] It can be understood that the second plate body 400 is located on the side of the fan facing the wall. After the range hood is installed, the second plate body 400 is also attached to the wall and fixedly connected to the wall. The second plate body 400 and the first plate body 100 together constitute the back plate of the range hood, which provides support and fixation for the installation of the range hood, and also plays a role in connecting and protecting other structures of the range hood.

[0063] Exemplarily, the first plate body 100 and the second plate body 400 are split, and a plurality of corresponding holes are provided on the first plate body 100 and the second plate body 400, and screw fasteners are provided in the holes to connect the first plate body 100 and the second plate body 400 together. This connection method is simple and reliable, and can improve the sealing and stability of the fan and the flue. Of course, the first plate body 100 and the second plate body 400 can also be connected in other ways, as long as the strength and sealing requirements after the connection are guaranteed, and this application does not limit this.

[0064] The split-type setting can realize the separate manufacturing of the first plate body 100 and the second plate body 400, and the processing difficulty is relatively low. Among them, the first plate body 100 corresponds to the location of the flue, and the second plate body 400 corresponds to the location of the fan. The split-type setting can also better adapt to different installation environments and requirements, and is convenient for installers to install the fan and flue separately. For larger range hood equipment, it can reduce the difficulty of installation and subsequent maintenance.

[0065] The top of the second plate 400 extends to the top of the range hood. The electric control box of the range hood is usually arranged on the top wall of the range hood. By arranging the second wiring groove 600 on the second plate 400, the direction of the line can be guided so that the line can reach the electric control box at the top and achieve connection with the electric control box. By arranging the cover plate 500 on the second plate 400, the second plate 400 can be strengthened while providing protection for the line arranged in the second wiring groove 600.

[0066] In other embodiments, the third slot body 610 may also be configured to protrude away from the fan, and the corresponding fourth slot body 620 may be configured to protrude toward the fan. Regardless of how the protrusions are distributed between the third slot body 610 and the fourth slot body 620, the cross-sectional dimensions of the second wiring groove 600 formed by the third slot body 610 and the fourth slot body 620 correspond to the first entrance 330, so that the first plate body 100 and the second plate body 400 fit better, thereby improving the sealing effect at the first entrance 330.

[0067] Exemplarily, the third trough body 610 and the fourth trough body 620 may also be manufactured by a sheet metal stamping process, which has the characteristics of low processing difficulty and small error, and is easy to implement.

[0068] Combination Figure 1 and 2 As shown, in some embodiments, the reinforcement member 200 is arranged in the horizontal direction ( Figure 2 The first wiring trough 300 extends in the same direction as the reinforcing member 200; the cover plate 500 extends in the vertical direction ( Figure 2 The second wiring groove 600 extends in the Y direction (in the Y direction), and the extension direction of the second wiring groove 600 is consistent with the extension direction of the cover plate 500.

[0069] The first plate 100 is located on one side of the flue close to the wall. In order to avoid occupying the flue space and ensure the smoothness of the flue, the electrical equipment installed near the flue is usually distributed at both ends of the flue. Figure 2 At both ends of the X direction in the first wiring slot 300, the extension direction is set to the horizontal direction ( Figure 2 The X direction in the guide groove can facilitate the lines of various electrical devices to enter and exit the first guide groove to reduce the exposure of the lines.

[0070] There is a certain height difference between the first wiring trough 300 and the position of the electric control box. By setting the extension direction of the second wiring trough 600 to the vertical direction ( Figure 2 The vertical arrangement of the wiring trough 300 can guide the wiring in the first wiring trough 300 to the electric control box to achieve connection with the electric control box, and the vertical arrangement of the wiring trough 300 can shorten the wiring path of the wiring and keep the wiring neat and orderly.

[0071] Figure 7 for Figure 6 Enlarged view of point C in the middle; Figure 8 for Figure 6 Enlarged view of D in the middle. Figure 6 and Figure 7 As shown, in some embodiments, at least one latching member 510 is provided on the cover plate 500, and the latching member 510 is inclined relative to the cover plate 500; at least one latching portion is provided on the second plate body 400, and the latching portion corresponds one-to-one to the latching member 510; the cover plate 500 is attached to the second plate body 400 and slides relative to the second plate body 400, and when the latching member 510 slides to the latching portion, the latching member 510 is latched in the latching portion; when the cover plate 500 slides in the opposite direction, the latching member 510 is disengaged from the latching portion.

[0072] Exemplarily, a notch 520 is provided in the extension direction of the cover plate 500, one side of the notch 520 is connected to the side of the extension direction of the cover plate 500, the blocking member 510 is provided in the notch 520 and connected to the side wall at the notch 520, the extension direction of the blocking member 510 is consistent with the extension direction of the cover plate 500, the end of the blocking member 510 connected to the cover plate 500 has a bending portion 511, and the bending portion 511 extends in a direction away from the cover plate 500; the end of the blocking member 510 away from the cover plate 500 has a guide portion 512, and the guide portion 512 also extends in a direction away from the cover plate 500.

[0073] When installing the cover plate 500 on the second plate body 400, firstly attach the cover plate 500 to the second plate body 400 and Figure 2 When sliding in the middle-Y direction, the guide portion 512 on the blocking member 510 first contacts the engaging portion, and as the cover plate 500 moves, the bending portion 511 engages with the engaging portion to limit the further movement of the cover plate 500. At this time, the connection between the cover plate 500 and the second plate body 400 can be achieved.

[0074] Furthermore, the cover plate 500 and the second plate body 400 are fastened together by screws to limit the cover plate 500 from moving along the Figure 2 The second plate 400 is separated from the second plate 400 by moving in the +Y direction.

[0075] In some embodiments, the engaging portion is a groove 410 protruding away from the cover plate 500 , an opening 420 is provided on a groove wall of the groove 410 , and the engaging member 510 is inserted into the opening 420 .

[0076] The shape of the groove 410 matches the shape of the stopper 510. When the stopper 510 slides to the engaging portion, it can be embedded in the groove 410, thereby improving the adhesion effect between the cover plate 500 and the second plate 400. Figure 2 On one side of the middle-Y direction, when the blocking member 510 slides to the locking portion, the guide portion 512 first penetrates into the opening 420 and reaches the side of the second plate 400 away from the cover 500. As the cover 500 moves, the bent portion 511 will be locked at the opening 420, and the height of the bent portion 511 is adapted to the depth of the groove 410, so that the bent portion 511 can be embedded in the groove 410, so that after the blocking member 510 is locked with the locking portion, the cover 500 and the second plate 400 maintain an adhesion effect.

[0077] Combination Figure 2 and Figure 3 As shown, in some embodiments, a first mounting portion 110 is provided on the first plate 100 , a second mounting portion 210 is provided at a position of the reinforcement 200 corresponding to the first mounting portion 110 , and the second plate 400 is connected to the first mounting portion 110 and the second mounting portion 210 .

[0078] Specifically, the first mounting portion 110 is a first plate body 100 disposed toward Figure 2 The second mounting portion 210 is a portion extending in the +Y direction of the reinforcing member 200. Figure 2 In the part extending in the +Y direction, the first slot body 310 extends to the second mounting portion 210, and the second slot body 320 extends to the first mounting portion 110 to form a first entrance 330. The second plate body 400, the first mounting portion 110 and the second mounting portion 210 can be fastened and connected by connecting members such as screws, so that there is a good adhesion effect between the three, and the sealing of the connection between the first wiring groove 300 and the second wiring groove 600 is ensured. In addition, the second plate body 400 is connected to the first mounting portion 110 and the second mounting portion 210, which can also reduce the occupied area of ​​the first plate body 100.

[0079] Combination Figure 2 As shown, in some embodiments, the first plate body 100 is further provided with at least one reinforcing rib 120 protruding away from the flue.

[0080] Exemplarily, the reinforcing ribs 120 include an annular profile and a linear profile disposed on the first plate body 100, wherein the linear profile is disposed inside the annular profile, and both the annular profile and the linear profile can be formed by a sheet metal stamping process. Of course, the reinforcing ribs 120 can also be profiles of other shapes, or a reinforcing structure connected to the first plate body 100. This application does not limit the number, shape, size, and arrangement of the reinforcing ribs 120. Any rib that can strengthen the first plate body 100 and does not affect the normal installation of the rear plate of the range hood is within the protection scope of this application.

[0081] Preferably, the reinforcing rib 120 is arranged along Figure 2 The distribution length in the X direction is the same as the length along the first wiring groove 300. Figure 2 The lengths in the X direction are equal to each other, so as to ensure the strengthening effect on the first plate body 100 .

[0082] Combination Figure 3 As shown, in some embodiments, a third plate body 700 is further included. The third plate body 700 is used to be set at the bottom of the flue.

An oil collecting groove 710 is opened on the third plate body 700, and at least one oil drain hole 720 is opened at the bottom of the oil collecting groove 710.

[0083] Exemplarily, the third plate body 700 and the first plate body 100 are integrally formed. By arranging the third plate body 700 at the bottom of the flue, the dirty oil flowing down from the first plate body 100 can be effectively received. Compared with the split third plate body 700 and the first plate body 100, the dirty oil can be effectively prevented from seeping out through the joints between the third plate body 700 and the first plate body 100, thereby reducing the difficulty of cleaning.

[0084] An oil cup may also be installed at the bottom of the third plate 700, and the opening 420 of the oil cup corresponds to the oil drain hole 720, so that the dirty oil collected by the oil collecting groove 710 can enter the oil cup through the oil drain hole 720 and be collected, which is convenient for users to clean.

[0085] On the other hand, the present application provides a range hood, comprising a range hood body and a range hood rear plate provided in any of the above embodiments, wherein the range hood rear plate is connected to a side of the range hood body close to the wall.

[0086] The rear plate of the range hood has been described in detail in the above embodiments and will not be described again here.

[0087] For example, the range hood body may be a side suction type or a top suction type range hood, etc. By arranging the range hood rear plate provided by the embodiment of the present application on the range hood body, the influence of the wiring arrangement in the range hood on the flue can be reduced, and the air circulation in the flue can be ensured.

[0088] Specifically, the back plate of the range hood provided by the present application forms the first wiring groove 300 by forming the reinforcement 200 and the first plate 100 by means of press-forming, and forms the second wiring groove 600 by forming the second plate 400 and the cover plate 500 by means of press-forming, which can facilitate the arrangement of the lines inside the range hood. When the total width L of the first wiring groove 300 required for wiring is constant, the second groove 320 is set to protrude in the direction away from the flue, which can reduce the height of the first groove 310 protruding in the direction of the flue, thereby reducing the occupation of the space in the flue, so as to prevent the first wiring groove 300 from obstructing the smooth flow of air in the flue, and solve the problem of affecting the air circulation in the flue caused by the arrangement of the lines in the range hood.

[0089] So far, the technical solution of the present application has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to these specific embodiments, and the above embodiments are only used to illustrate the technical solution of the present application rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
