Description

Technical Field

[0001] The utility model relates to the technical field of range hoods, in particular to a switch panel installation structure of a range hood. Background Art

[0002] A range hood is a kitchen appliance that purifies the kitchen environment. During the research, development and manufacturing process of range hoods, the appearance of the range hood has become the focus of attention of most kitchen appliance manufacturers, especially in the final stage of range hood assembly. The requirements for the assembly of the outer panels (such as the switch panel) of the range hood are very strict, which leads to a very complex installation structure of the outer panels, which also makes the assembly process of the outer panels very cumbersome. For example, the installation structure and assembly method of the upper panel located above the smoke inlet of a side-suction range hood are very complicated, especially when disassembling, the outer panel can only be removed after the outer shell of the range hood is basically disassembled, and the disassembly process is relatively cumbersome.

[0003] In order to solve the above technical problems, a Chinese utility model patent application with application number CN201920992477.0 (authorization announcement number: CN210568699U) discloses a range hood and its outer panel mounting structure, wherein the outer panel is mounted on the outer surface of the range hood, the upper edge of the outer panel is fixed to the range hood through a fixing plate, and the lower edge of the outer panel forms a blocking portion, which is in the form of a sheet and can be inserted into the range hood, and the blocking portion is used to prevent the other side edge of the outer panel from being separated from the range hood. A fixing plate is provided at the inner upper part of the outer panel body, and a concave cavity is formed on the fixing plate, which is connected to the edge of the fixing plate, and a convex portion is formed in the range hood, which is placed in the concave cavity, and the two are fixed by screws and other components.

[0004] The outer panel (switch panel) installation structure in the above patent application still has certain shortcomings: when the fixing plate of the outer panel is assembled with the raised part on the main body of the range hood, the fixing plate of the outer panel needs to be extended into the casing, and the concave cavity on the fixing plate needs to be aligned with the raised part in the assembly direction so that the raised part can slide into the concave cavity of the fixing plate. The operation process of this installation structure is still relatively cumbersome, requiring high precision and patience, resulting in reduced installation efficiency. Especially when adjusting the size or calibrating, if accurate alignment cannot be achieved after multiple attempts, the installation time will be further increased.

[0005] Therefore, the switch panel installation structure of the existing range hood needs to be further improved. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a switch panel installation structure of a range hood which can effectively simplify the disassembly and assembly process of the switch panel and improve the disassembly efficiency in view of the current status of the prior art.

[0007] The technical solution adopted by the utility model to solve the above technical problems is: a switch panel installation structure of a range hood, comprising:

[0008] Body;

[0009] A switch panel is arranged on the front side wall of the machine body;

[0010] The back of the switch panel is connected to the front side wall of the body by a snap assembly for limiting the movement of the two in the front and rear directions. The back of the switch panel has a mounting shelf extending left and right and bent backward at a position adjacent to its top side edge. The mounting shelf is placed on the top of the front side edge area of ​​the top plate of the body and is connected to it by a connecting piece.

[0011] In order to simplify the structure of the buckle assembly, the back side of the switch panel has a limit buckle extending backward, and the end of the limit buckle away from the switch panel has a limit portion protruding to the left and / or right side, and a limit socket is provided on the front side wall of the body. After the limit buckle is inserted into the limit socket, its limit portion abuts against the rear side of the outer peripheral edge of the limit socket, and the limit buckle and the limit socket together constitute the buckle assembly.

[0012] In order to make the switch panel fit firmly with the front side wall of the body and ensure that it is accurately installed in the up and down directions, the limit buckle is a horizontally extended plate structure as a whole, and its limit portion has a first end connected to the main body of the limit buckle and a second end away from the main body of the limit buckle, and the front side edge of the limit portion gradually tilts forward from the second end to the first end to form a guiding bevel.

[0013] As an improvement, the limiting socket is a strip-shaped opening extending left and right, and the side of the strip-shaped opening used to cooperate with the limiting part of the limiting buckle is recorded as the locking side, and the side opposite to the locking side is recorded as the unlocking side, and the width dimension of the strip-shaped opening adjacent to its locking side is smaller than the width dimension of the strip-shaped opening adjacent to its unlocking side.

[0014] As an improvement, the width dimension of the strip-shaped opening adjacent to its locking side is consistent with the thickness of the limiting buckle.

[0015] In order to ensure the reliability of the installation of the switch panel, the buckle assembly has at least two groups arranged at intervals along the left and right directions.

[0016] In order to ensure the convenience of switch panel installation, the limiting parts of the limiting buckles of each group of buckle assemblies protrude in the same direction relative to the main body of the limiting buckle. When installing, the switch panel only needs to be inserted into the limiting socket along the guiding bevel of the limiting buckle in the same direction.

[0017] In order to ensure the flatness of the top surface of the range hood, the front edge area of ​​the top plate of the body is recessed downward relative to the top main body to accommodate a placement recess for the mounting shelf. When the mounting shelf is placed in place in the placement recess, the top surface of the mounting shelf is flush with the top surface of the top plate of the body.

[0018] As an improvement, a first connecting hole is provided on the bottom wall of the shelf recess, a second connecting hole corresponding to the first connecting hole is provided on the mounting shelf, and the connecting member is inserted through the first connecting hole and the second connecting hole.

[0019] In order to prevent the ends of connecting parts such as screws from protruding upward and affecting the overall aesthetics, the second connecting hole on the mounting shelf is a countersunk hole, and the bottom of the mounting shelf forms a downwardly protruding protrusion in the area corresponding to the countersunk hole, and the top surface of the bottom wall of the shelf recessed area has a recessed groove for accommodating the protrusion.

[0020] In order to ensure the reliability of the connection between the switch panel and the machine body, the mounting shelf has at least two first connecting holes spaced apart in the left-right direction, and the second connecting holes also have at least two corresponding ones.

[0021] Considering that the panel body of the switch panel is generally a glass plate, in order to achieve connection with the body, the switch panel includes a panel body and a connecting bracket arranged on the back of the panel body, and the connecting bracket is formed with the limiting buckle and the mounting shelf.

[0022] As an improvement, the switch panel further comprises a switch assembly, which is arranged on the back side of the panel body and fixed to the connecting bracket.

[0023] Compared with the prior art, the advantages of the utility model are as follows: the switch panel mounting structure of the utility model adopts a combination of a snap assembly and a connector fixation (the mounting shelf and the top plate of the body are fixed by a connector), wherein the mounting partition on the switch panel is located at the top of the front edge area of ​​the top plate of the body, and during installation, it is only necessary to perform preliminary installation and positioning of the switch panel and the front side wall of the body through the snap assembly, and the mounting shelf can be matched with the front edge area of ​​the top plate (or after fine-tuning) in place, and then the mounting shelf can be directly fixed to the top of the body through the connector. During disassembly, first remove the connector, and then detach the snap assembly to complete the disassembly of the switch panel. The above disassembly and assembly method is simpler and more convenient to operate, which improves the disassembly and assembly efficiency and facilitates subsequent maintenance and replacement.

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0031] In the specification and claims of the present invention, terms indicating directions, such as "front", "rear", "up", "down", "left", "right", "side", "top", "bottom", etc., are used to describe various exemplary structural parts and elements of the present invention, but these terms are used here only for the purpose of convenience of description and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions are only used as explanations and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0032] Figure 1-Figure 6A preferred embodiment of the installation structure of the switch panel 2 of the range hood of the utility model is shown. The range hood includes a casing and a centrifugal fan arranged in the casing. The casing generally includes a fan frame 11 and a fume hood 12 arranged at the bottom of the fan frame 11. The inner cavity of the fan frame 11 is connected to the inner cavity of the fume hood 12. An air inlet 120 is provided on the front side wall of the fume hood 12, and external smoke can enter the fume hood 12 through the air inlet 120. The centrifugal fan is arranged in the fan frame 11. When the centrifugal fan is running, negative pressure is generated, and external oil smoke can be sucked into the fume hood 12 through the air inlet 120. An oil net is also provided at the air inlet 120 of the fume hood 12 for filtering oil smoke. An oil cup 14 is provided at the bottom of the fume hood 12. The oil cup 14 is in the shape of a long strip extending left and right, and is used to receive the oil stains flowing down from the fume hood 12. The front part of the smoke hood 12 is also provided with a smoke shield 13 that can be deflected forward and backward relative to the smoke hood 12. The smoke shield 13 is connected to the main body of the smoke hood 12 through a hinge motion mechanism, and can be deflected forward to open the air inlet 120 and deflected backward to block and close the air inlet 120. The hinge motion mechanism used to drive the smoke shield 13 to deflect can adopt a conventional hinge motion mechanism in the prior art, which will not be described in detail here.

[0033] See also Figure 5 , the installation structure of the switch panel is described by taking a close-suction range hood as an example. The front side wall of the range hood includes an inclined wall 1231 on which the air inlet 120 is arranged and a vertical wall 1232 extending vertically corresponding to the air inlet 120 (i.e., the smoke baffle 13). The top of the vertical wall 1232 is connected to the top plate 122 of the smoke hood 12. The switch panel 2 is installed on the front side of the vertical wall 1232. Considering that the rear side (i.e., the back side) of the switch panel 2 has relatively protruding parts (such as the switch assembly 23, etc.), an opening is provided on the vertical wall 1232, such as Figure 2 The front side wall of the smoke collecting hood 12 shown is only provided with a flange extending upward from the bottom, and a limit position insertion opening 121 is correspondingly provided on the flange.

[0034] The front edge area of ​​the top of the smoke hood 12 is recessed downward relative to the main body of the top to form a shelf recess 1220 for accommodating the installation shelf 221. The shelf recess 1220 is also in the shape of a long strip extending in the left and right directions. The bottom wall of the shelf recess 1220 also has a concave recess 1221, which is used to accommodate the raised portion 2211 on the installation shelf 221 of the switch panel 2. The bottom wall of the recess 1221 is provided with a first connection hole 1223. Considering that the switch panel 2 will move left and right during installation, the recess 1221 also has a sufficient size in the left and right directions, and the first connection hole 1223 is offset to one side of the recess 1221 in the left and right directions. There are multiple recesses 1221 arranged at intervals along the left and right directions, and there are also multiple first connection holes 1223.

[0035] See also Figure 3 and Figure 6 The switch panel 2 is a plate-like structure extending left and right as a whole, and its size in the up and down direction is basically consistent with the up and down size of the vertical wall of the smoke hood 12. The switch panel 2 includes a panel body 21, a switch assembly 23 and a connecting bracket 22. The connecting bracket 22 is pasted on the back of the panel body 21, and its top edge has a flange that bends and extends backward as a mounting shelf 221, and the mounting shelf 221 is also a long strip extending in the left and right direction. The bottom edge of the connecting bracket 22 has limiting buckles 222 that are arranged in sequence at intervals in the left and right directions. Each limiting buckle 222 is a horizontally arranged plate-like structure as a whole, which extends backward from the bottom edge of the main body of the connecting bracket 22, and has a limiting portion 2220 protruding to the left and / or right at the end away from the switch panel 2, such as Figure 3 As shown, the limiting parts 2220 of this embodiment all protrude toward the right side, that is, protrude toward the same side. Specifically, the limiting part 2220 has a first end 2221 connected to the main body of the limiting buckle 222 and a second end 2222 away from the main body of the limiting buckle 222. The front side edge of the limiting part 2220 gradually tilts forward from the second end 2222 to the first end 2221 to form a guiding bevel 2223.

[0036] The limiting buckle 222 on the connecting bracket 22 can form a limiting fit with the limiting socket 121 on the front side wall of the smoke hood 12. Specifically, the limiting socket 121 is a strip-shaped opening extending left and right, and the side of the strip-shaped opening used for limiting fit with the limiting portion 2220 of the limiting buckle 222 is recorded as the locking side 1211, and the side opposite to the locking side 1211 is recorded as the unlocking side 1212, wherein the width dimension of the strip-shaped opening adjacent to its locking side 1211 is smaller than the width dimension of the strip-shaped opening adjacent to its unlocking side 1212, and the width dimension of the strip-shaped opening adjacent to its locking side 1211 is consistent with the thickness of the limiting buckle 222. The upper edge of the strip-shaped opening corresponding to the portion located between the locking side 1211 and the unlocking side 1212 is also designed as a guide bevel structure. During installation, the second end 2222 of the limit buckle 222 can be inserted into the limit socket 121 first, and then the switch panel 2 can be aligned and slid to the right along the limit socket 121. After sliding into place, the limit buckle 222 is stuck in the locking side 1211 of the limit socket 121. Since the width of the limit socket 121 adjacent to its locking side 1211 is consistent with the thickness of the limit buckle 222, the switch panel 2 can be accurately positioned in the vertical direction to avoid the problem of shaking up and down. At the same time, due to the guiding effect of the guiding bevel 2223 on the front side of the limit portion 2220 of the limit buckle 222, the limit portion 2220 corresponds to the rear side of the outer peripheral edge of the limit socket 121, and the back side of the switch panel 2 can also fit the front side of the vertical wall of the smoke hood 12, thereby limiting the switch panel 2 in the front-to-back direction, avoiding the problem of shaking in the front-to-back direction.

[0037] The above-mentioned limiting buckle 222 and limiting socket 121 together constitute the buckle assembly of this embodiment.

[0038] The mounting shelf 221 of the connecting bracket 22 is provided with a second connecting hole 2210 corresponding to the first connecting hole 1223 at the top of the smoke hood 12. During installation, the first connecting hole 1223 and the second connecting hole 2210 can be fixed by means of a connecting piece inserted through them. The connecting piece can be a screw. The second connecting hole 2210 on the mounting shelf 221 is a countersunk hole, and the use of a countersunk hole can prevent the end of the screw from protruding upward, affecting the overall aesthetics. The mounting partition is a sheet metal part, and the countersunk hole can be formed by stamping. In this way, a downwardly protruding protrusion 2211 will be formed at the bottom of the mounting shelf 221 in the area corresponding to the above-mentioned countersunk hole, and the protrusion 2211 corresponds to the recessed groove 1221 on the bottom wall of the shelf recessed area 1220 at the top of the smoke hood 12. The above-mentioned protrusion 2211 and the recessed groove 1221 can also play a guiding and limiting role in the left and right movement of the switch panel 2.

[0039] The installation structure of the switch panel 2 of this embodiment is a combination of a snap assembly and a connector (the installation shelf 221 is fixed to the top plate 122 of the body 1 by a connector), wherein the installation partition on the switch panel 2 is located at the top of the front edge area of ​​the top plate 122 of the body 1. During installation, it is only necessary to perform preliminary installation and positioning of the switch panel 2 and the front side wall of the body 1 through the snap assembly, and the installation shelf 221 can be matched with the front edge area of ​​the top plate 122 (or after fine-tuning) in place, and then the installation shelf 221 can be directly fixed to the top of the body 1 through the connector. The installation partition is located above the top, which is also convenient for the operator to observe and fine-tune the position of the switch panel 2, thereby improving the assembly efficiency. During disassembly, the connector is first removed, and then the snap assembly is detached to complete the disassembly of the switch panel 2. The above disassembly and assembly method is simpler and convenient to operate, thereby improving the disassembly and assembly efficiency.
