Description

Technical Field

[0001] The utility model relates to the technical field of range hoods, in particular to a smoke collecting hood and a range hood. Background Art

[0002] A range hood (also known as a range hood) consists of a fume hood and a main housing with a fan installed inside. In the fume hood, the bent transition edge at the top center of the front panel, along with the left and right top panels, forms a mounting opening. The bottom of the main housing connects to this mounting opening at the top of the fume hood.

[0003] Existing front panels have an integrally formed bend transition edge at the top center. Therefore, during the front panel manufacturing process, material on both sides of the bend transition edge must be removed, reducing material utilization. Furthermore, the presence of the bend transition edge increases the complexity of the front panel structure, thus increasing the number of processing steps, processing time, and cost, hindering processing efficiency. It also increases mold investment and reduces mold life, further increasing costs. Utility Model Content

[0038] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0039] This embodiment provides a range hood comprising a smoke hood and a main housing with a fan installed therein. The top of the smoke hood is provided with a mounting opening, and the bottom of the main housing is connected to the mounting opening installed on the top of the smoke hood.

[0040] Existing smoke hoods include a front panel and two top panels, which are mounted on the left and right sides of the top of the front panel. A bent transition edge is integrally formed in the center of the top of the front panel. The bent transition edge and the two top panels form a mounting opening. During the processing of the existing front panel, material on both sides of the bent transition edge must be removed, reducing material utilization. Furthermore, the presence of the bent transition edge increases the complexity of the front panel structure, increasing the number of processing steps, processing time, and cost, affecting the improvement of processing efficiency. It also increases the investment cost of the processing mold, reduces the mold's service life, and further increases costs.

[0041] To solve the above problems, Figure 1 and Figure 2 As shown, the present embodiment also proposes a smoke hood, which includes a front panel 1, two top panels 2 and a connecting plate 3, wherein the two top panels 2 are respectively installed on the left and right sides of the top of the front panel 1. The front end of the connecting plate 3 is detachably connected to the front panel 1, and the two ends of the connecting plate 3 in the length direction (left and right direction in the figure) are respectively detachably connected to the two top panels 2, and the connecting plate 3 and the two top panels 2 form a mounting opening. The smoke hood of this embodiment is configured so that the front panel 1 and the connecting plate 3 are arranged as a split structure, so that the front panel 1 does not need to be integrally provided with a bending transition edge in the middle position, thereby simplifying the structure of the front panel 1, improving the material utilization rate during the processing of the front panel 1, simplifying the processing steps of the front panel 1, reducing the processing cost, and improving the processing efficiency. At the same time, the investment cost of the processing mold of the front panel 1 is simplified, the service life of the mold is extended, and the cost is further reduced. In addition, since the front panel 1 and the connecting plate 3 are a split structure, it is convenient to spray paint the front panel 1 and the connecting plate 3, avoiding the problem of blind spots in the spray painting.

[0042] like Figure 3 and Figure 4 As shown, the connecting plate 3 comprises a main plate 31 and ear plates 33. The main plate 31 is provided with ear plates 33 at both ends along its length. The adjacent ends of the two top plates 2 are each provided with a limit flange 20. The limit flange 20 defines a first limit groove 21, and the ear plates 33 snap into the corresponding first limit groove 21. The snap-fitting engagement of the ear plates 33 with the first limit groove 21 secures the left and right ends of the connecting plate 3 to the left and right top plates 2, respectively. This enhances the structural strength of the smoke hood and improves the assembly efficiency of the connecting plate 3.

[0043] Furthermore, if Figure 5 As shown, second retaining grooves 330 are provided at both ends of the main body plate 31 along its length, respectively, between the corresponding ear plates 33. When the two ear plates 33 are respectively engaged with the corresponding first retaining grooves 21, the retaining flanges 20 of the two top plates 2 are respectively engaged with the corresponding second retaining grooves 330. When the ear plates 33 engage with the first retaining grooves 21, the retaining flanges 20 also engage with the second retaining grooves 330, thereby achieving a mutually engaged assembly between the connecting plate 3 and the two top plates 2. This improves the stability of the connecting plate 3 assembly and further enhances the structural strength of the smoke hood.

[0044] like Figure 3 As shown, the limiting flange 20 further defines a guide groove 22 that communicates with the first limiting groove 21. The lug plate 33 slides into or out of the first limiting groove 21 through the guide groove 22. The provision of the guide groove 22 facilitates rapid alignment of the lug plate 33 with the first limiting groove 21, thereby achieving a snap-fit ​​engagement between the lug plate 33 and the first limiting groove 21, thereby improving the assembly efficiency of the connecting plate 3.

[0045] Specifically, the guide groove 22 extends along the height direction of the top plate 2 (the vertical direction in the figure) and penetrates the bottom end of the limiting flange 20 to form an opening at the bottom end of the limiting flange 20. The front end of the guide groove 22 is connected to the first limiting groove 21. When assembling the connecting plate 3, the ear plate 33 is moved from bottom to top to the top of the guide groove 22 so that the ear plate 33 (the second limiting groove 330) is aligned with the first limiting groove 21. Then, the connecting plate 3 is pushed from back to front until the front end of the connecting plate 3 abuts against the inner side of the front panel 1. At this time, the ear plate 33 is engaged in the first limiting groove 21, and the limiting flange 20 is engaged in the second limiting groove 330, thereby realizing the mutual engagement and assembly of the connecting plate 3 and the two top plates 2.

[0046] Furthermore, if Figure 5 As shown, at least one sidewall of the second limiting groove 330 is provided with a guiding bevel 331. Specifically, the sidewalls of the second limiting groove 330 formed by the lugs 33 have guiding bevels 331, so that the entrance of the second limiting groove 330 forms a flared structure, which can provide guidance for the assembly of the connecting plate 3, facilitating the rapid engagement of the limiting flange 20 within the second limiting groove 330 under the guidance of the guiding bevels 331, thereby improving the assembly efficiency of the connecting plate 3.

[0047] Specifically, if Figure 5As shown, first side panels 32 extend downward from both ends of the main body panel 31 along its length, and lugs 33 extend outward from the bottom of the first side panels 32. When the lugs 33 are engaged with the corresponding first retaining grooves 21, the two first side panels 32 respectively engage with the corresponding retaining flanges 20. Both left and right ends of the main body panel 31 are flanged downward to form the first side panels 32, enhancing the structural strength of the connecting panel 3. A second retaining groove 330 is formed between the first side panels 32 and the lugs 33. The first side panels 32 increase the contact area between the connecting panel 3 and the top panel 2, improving the assembly strength and stability of the connecting panel 3.

[0048] In this embodiment, a second side panel 34 extends downward from the front end of the main panel 31 and is detachably connected to the front panel 1. The front end of the main panel 31 is flanged downward to form the second side panel 34, thereby enhancing the structural strength of the connecting panel 3. For example, the connecting panel 3 and the front panel 1 are fixedly connected via screws. This not only enhances the connection strength between the connecting panel 3 and the front panel 1, but also facilitates assembly of the connecting panel 3 and improves assembly efficiency. In other embodiments, the connecting panel 3 and the front panel 1 may also be fixedly connected via rivets, bolts, or other methods.

[0049] Specifically, if Figure 3 and Figure 5 As shown, the front panel 1 is provided with an avoidance groove 11, and a first through hole 12 is provided in the avoidance groove 11. The second side panel 34 is provided with a second through hole 3431, and the first through hole 12 is connected to the second through hole 3431 in a one-to-one correspondence and is connected by a fastener. The fasteners in this embodiment are screws, and the front panel 1 and the connecting plate 3 are fixedly connected by screws. The screws pass through the connected first through hole 12 and the second through hole 3431 in sequence and are locked with the nut. At the same time, the head of the screw is located in the avoidance groove 11, thereby preventing the head of the screw from protruding from the front side of the front panel 1 and preventing the screw from interfering with the control panel to be installed on the front panel 1.

[0050] like Figure 5As shown, the second side panel 34 has a first step structure in the shape of a step, and the bend of the avoidance groove 11 on the front panel 1 forms a second step structure in the shape of a step, and the first step structure abuts the upper edge of the inner side surface of the second step structure. Specifically, the second side panel 34 includes a first flange 341, a second flange 342, and a third flange 343, which are sequentially connected in a step structure. The top end of the first flange 341 is connected to the main panel 31, and the third flange 343 is located at the rear side of the first flange 341, and a second through hole 3431 is formed in the third flange 343. When the second side panel 34 is fixedly connected to the front panel 1, the first flange 341 is in contact with the inner side surface of the front panel 1, and the third flange 343 is in contact with the inner side surface of the front panel 1 facing the avoidance groove 11 and is connected by fasteners. Due to the presence of the avoidance groove 11, the inner side surface of the front panel 1 forms a second step structure at the bend of the avoidance groove 11, and the second flange 342 overlaps the step surface located above in the second step structure. The second side panel 34 of this embodiment and the front panel 1 are a stepped structure that overlaps and matches, which improves the assembly strength and stability of the second side panel 34 and the front panel 1. When the connecting plate 3 is assembled, when the connecting plate 3 is pushed into place from the back to the front, the first flange 341 fits with the inner side surface of the front panel 1, and the third flange 343 fits with the outer top surface of the avoidance groove 11, so as to achieve a stop limit for the connecting plate 3 in the front-to-back direction. After the connecting plate 3 and the two top plates 2 are mutually clamped and assembled, the front panel 1 and the third flange 343 are locked by fasteners.

[0051] Specifically, the main panel 31 is provided with two second side panels 34 spaced apart along the left-right direction. The third flange 343 of the second side panel 34 is provided with two second through-holes 3431 spaced apart along the left-right direction. The front panel 1 is provided with two escape grooves 11 spaced apart along the left-right direction. Each escape groove 11 has two corresponding first through-holes 12, allowing each third flange 343 to be fastened to the front panel 1 via two fasteners. In other embodiments, the number and position of both the second side panels 34 and the second through-holes 3431 can be flexibly adjusted according to installation requirements and are not specifically limited here.

[0052] like Figure 5 As shown, in this embodiment, a semicircular guide groove 3432 is provided at the bottom of the third flange 343, so that the connecting plate 3 has an installation guide in the mold, which prevents the base material of the connecting plate 3 from being placed in the wrong position or direction in the mold, has a good anti-foolproof effect, and is conducive to improving the processing efficiency of the connecting plate 3.

[0053] It should be noted that if Figure 6As shown, in this embodiment, the rear end of the main plate 31 extends downward to form a third side plate 35 that connects to the main housing. The third side plate 35 forms the side wall of the mounting opening and can be securely mounted to the main housing. Specifically, the rear end of the main plate 31 is flanged downward to form the third side plate 35, further enhancing the structural strength of the connecting plate 3.

[0054] The above embodiments merely illustrate the basic principles and features of the present invention. The present invention is not limited to the above embodiments. Various changes and modifications are possible without departing from the spirit and scope of the present invention. Such changes and modifications are within the scope of the present invention.
