Description

Technical Field

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

[0002] A range hood is a kitchen appliance that purifies the kitchen environment. It operates based on the principles of fluid dynamics. A centrifugal fan installed inside the range hood draws in and exhausts cooking fumes, while a filter removes some grease particles. A centrifugal fan consists of a volute, an impeller mounted within the volute, and a motor that drives the impeller. As the impeller rotates, negative pressure is generated at the fan's center, drawing cooking fumes from beneath the range hood into the fan. After being accelerated by the fan, the volute collects them and guides them out of the room.

[0003] The switch panel of the range hood is generally connected to the body of the range hood by providing a connecting bracket on the back of the panel body. For example, the Chinese utility model patent application with application number 201920903056.6 discloses a panel installation structure, including a shell having a smoke inlet chamber and a panel that can cover the front side wall of the shell. A panel bracket close to the panel is provided on the back of the panel, and a card extending backward is provided at the side edge of the panel bracket. Correspondingly, a slot is provided on the side frame of the shell for the card to be inserted therein and slide downward for a certain distance; a limiting component that can make the lower part of the panel bracket close to the shell is provided on the lower part of the panel bracket and the front side wall of the shell.

[0004] However, the panel mounting structure in the above patent application still has certain deficiencies. The panel bracket on the back of the panel body is an integral bracket structure, which is less versatile and can generally only be applied to specific range hoods with a width of 900 mm. It cannot be applied to wider or narrower range hoods. In addition, the clips on the bracket are oriented in a single direction and can only be installed in a single direction during installation, requiring fool-proofing. Utility Model Content

[0005] The first technical problem to be solved by the present invention is to provide a panel assembly installation structure for range hoods with good versatility and adaptability to models of different widths and sizes, in view of the current status of the existing technology.

[0006] The second technical problem to be solved by the present invention is to provide a range hood adopting the above-mentioned panel assembly installation structure in view of the current status of the existing technology.

[0007] The technical solution adopted by the present invention to solve the first technical problem is: a panel assembly mounting structure of a range hood, which is applied to a panel body. The panel body is in the shape of a long strip as a whole and includes:

[0008] At least two panel brackets are arranged in sequence along the length direction of the panel body. The structure of each panel bracket is the same. Each panel bracket includes a bracket body for being attached to the back of the panel body and a limiting buckle extending outward from the bracket body.

[0009] In order to enable the panel assembly to be installed in two directions (i.e., to the left or to the right), each panel bracket includes two limit clips spaced apart in front and back, and each limit clip includes a first limit protrusion extending to the left and a second limit protrusion extending to the right.

[0010] In order to ensure the versatility of the panel bracket, the first and second limiting protrusions of the limiting buckle are arranged symmetrically. The above structural design ensures that a single panel bracket can still meet the position limit requirements after rotating symmetrically around its own center, and has high versatility.

[0011] In order to ensure that the limiting buckles of the panel bracket are smoothly inserted or plugged into the fixed position of the range hood, the top of each limiting buckle is also provided with a guide insert extending outward.

[0012] As an improvement, the guide inserts of the two limiting buckles on the panel bracket are gradually inclined toward the side where the two limit buckles are close to each other.

[0013] As an improvement, there are three panel brackets, one of which is located in the middle of the length direction of the panel body, and the other two are located on the left and right sides of the panel bracket in the middle position.

[0014] As an improvement, the panel body is a glass panel.

[0015] As an improvement, the panel bracket is connected to the back side of the panel body by gluing.

[0016] The technical solution adopted by the present invention to solve the second technical problem is: a range hood, comprising a casing and a panel, wherein the panel is arranged on the casing through the above-mentioned panel assembly mounting structure of the range hood.

[0017] As an improvement, the above-mentioned panel assembly can be optionally installed on a close-suction range hood, the casing includes a fan frame and a smoke collection hood arranged at the bottom of the fan frame, an air inlet is provided on the front side wall of the smoke collection hood, and the panel is arranged on the front side wall of the smoke collection hood in an area above the air inlet.

[0018] Compared with the prior art, the advantages of the present invention are as follows: two or more panel brackets are provided on the back of the panel body, and each panel bracket is designed to have the same structure, so no foolproofing is required during installation, and the invention can be adapted to range hoods of different widths, such as being applicable to range hoods of 900mm width, 800mm width, and 1000mm width. During installation, it is only necessary to fix each panel bracket to a corresponding position on the back of the panel body according to the corresponding connection position of the range hood casing. In the preferred embodiment, the limiting protrusions of the two limiting buckles of the panel bracket are also symmetrically designed. Therefore, no foolproofing is required when installing a single panel bracket. That is, whether it is rotated 180 degrees clockwise or 180 degrees counterclockwise, it will not affect the assembly, thereby improving the assembly efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0025] In the specification and claims of the present invention, directional terms such as "front," "back," "up," "down," "left," "right," "side," "top," and "bottom" are used to describe various exemplary structural parts and components of the present invention. However, these terms are used herein for convenience of description only and are based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present invention can be arranged in different orientations, these directional terms are intended for illustrative purposes only and should not be construed as limiting. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0026] Figure 1-Figure 5The present invention illustrates a panel assembly mounting structure for a range hood and a preferred embodiment of the range hood. The range hood includes a housing and a centrifugal fan disposed within the housing. The housing generally includes a fan frame 11 and a fume hood 12 disposed at the bottom of the fan frame 11. The interior of the fan frame 11 communicates with the interior of the fume hood 12. An air inlet is defined on the front sidewall of the fume hood 12, through which external smoke can enter the fume hood 12. The centrifugal fan is disposed within the fan frame 11. When in operation, the centrifugal fan generates negative pressure, allowing external oil smoke to be drawn into the fume hood 12 through the air inlet. A smoke shield 13 is also provided at the front of the fume hood 12, capable of pivoting forward and backward relative to the fume hood 12. The smoke shield 13 is connected to the main body of the fume hood 12 via a hinged mechanism. Specifically, the shield 13 can be pivoted forward to open the air inlet and pivoted backward to block and close the air inlet. The hinge motion mechanism for driving the smoke baffle 13 to deflect can adopt a conventional hinge motion mechanism in the prior art, which will not be described in detail here.

[0027] The range hood also includes a panel assembly, which is installed on the front side wall of the smoke hood 12 in the area above the air inlet. The mounting structure of the panel assembly is applied to the panel body 20, including a panel bracket 30 provided on the back of the panel body 20. The panel body 20 is in the shape of a long strip as a whole, and preferably a glass panel is used. There are at least two panel brackets 30, which are arranged in sequence along the length direction of the panel body 20. The panel brackets 30 of this embodiment have the same structure and can be connected to the back of the panel body 20 by gluing. No fool-proofing treatment is required during installation, and it can be adapted to range hoods of different widths, such as range hoods with a width of 900mm, 800mm, and 1000mm. During installation, it is only necessary to fix each panel bracket 30 to the corresponding position on the back of the panel body 20 according to the corresponding connection position of the range hood casing.

[0028] The panel bracket 30 includes a bracket body 31 for attaching to the back of the panel body 20 and a retaining clip 32 extending outward from the bracket body 31. The bracket body 31 is a plate structure that can be attached to the back of the panel body 20. The retaining clip 32 is designed as an integral part of the bracket body 31 and can be formed by stamping, bending, or other processing methods from the base plate of the bracket body 31. Each panel bracket 30 includes two retaining clips 32 spaced apart from each other. Each retaining clip 32 includes a first retaining protrusion 321 extending to the left and a second retaining protrusion 322 extending to the right. The first retaining protrusion 321 and the second retaining protrusion 322 of the retaining clip 32 are arranged symmetrically. The design of the first limiting protrusion 321 and the second limiting protrusion 322 enables the panel assembly to be installed in two directions (i.e., moving to the left or moving to the right) during installation. The symmetrical structural design enables a single panel bracket 30 to rotate symmetrically around its own center and still meet the position limit requirements, which has high versatility.

[0029] like Figure 2 As shown, a corresponding card hole 120 is provided on the front side wall of the smoke hood 12 to be engaged with the limit card buckle 32 of the panel assembly. The top of each limit card buckle 32 also has a guide plug 33 extending outward. The guide plugs 33 of the two limit card buckles 32 on the panel bracket 30 gradually tilt toward the side where the two are close to each other. In this way, it can ensure that the limit card buckles 32 of the panel bracket 30 are smoothly inserted or inserted into the corresponding card hole 120 of the range hood.

[0030] See also Figure 3 and Figure 4 In this embodiment, there are three panel brackets 30, one of which is located in the middle position in the length direction of the panel body 20, and the other two are located on the left and right sides of the panel bracket 30 in the middle position, respectively. Among them, the distance from the left panel bracket 30 to the panel bracket 30 in the middle position is the same as the distance from the right panel bracket 30 to the panel bracket 30 in the middle position.

[0031] The three-section panel bracket 30 of this embodiment has an identical structure, and there are no specific requirements for the bonding position or order of each panel bracket 30 on the glass panel. Furthermore, because each panel bracket 30 is centrally symmetrical, the entire panel assembly can be assembled on the device without having to determine its orientation, thereby improving assembly efficiency.
