Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0025] The following is combined with Figures 1 to 9 The fan cover fixing structure provided in this embodiment will be further described as follows:

[0026] Please refer to Figure 1 The present invention provides a fan cover fixing structure, including a door frame 1, an upper heat insulation plate 2 and a fan cover 3. The upper heat insulation plate 2 is installed on the top of the back side of the door frame 1 and is set perpendicular to the door frame 1. The fan cover 3 is fastened to the top surface of the upper heat insulation plate 2 by a cover fastener 8.

[0027] Reference Figure 5 The top of the fan cover 3 is equipped with a motor frame 4 via motor fasteners 7. There are at least two sets of motor fasteners 7. The motor frame 4 consists of a motor and a frame for fixing the motor. The frame is fastened to the fan cover 3 by the motor fasteners 7, which replaces the traditional installation method of multiple screws, realizes quick installation and improves installation efficiency. In this embodiment, there are three sets of motor fasteners 7, which are evenly distributed on the same ring with the motor shaft as the center. The motor fasteners 7 are fastened and fixed by rotating the motor frame 4.

[0028] Reference Figure 4 The instrument panel bracket 5 is installed on the top of the front side of the door frame 1 by means of the panel fastener 6. In this embodiment, the front side refers to the front side of the oven when it is in use. The door frame 1 is set on the front side of the oven and is used as the door.

[0029] Among them, "at least two" includes two or more cases, and in order to ensure that each set of motor fasteners 7 are fastened synchronously, they are evenly distributed on the same ring with the motor shaft as the center.

[0030] The embodiments of this utility model also disclose the following more optimized specific structures:

[0031] Reference Figure 6 The motor fastener 7 includes a deformable slot 71 and a limiting pivot 72. The deformable slot 71 is installed on the top of the fan cover 3, and the limiting pivot 72 is connected to the motor frame 4. The limiting pivot 72 and the frame of the motor frame 4 are integrally formed.

[0032] The deformation slot component 71 consists of a slot shell 711 and a limiting side slot 713 disposed on one side of the slot shell 711. A top-pressing limiting post 712 is fixedly connected to the top wall of the limiting side slot 713. The bottom end of the top-pressing limiting post 712 is a ball head, which facilitates the upward deformation of the slot shell 711 after pressing. The limiting pivot 72 consists of an L-shaped connecting frame 721 and a slot-in-slot locking block 722 installed at the end of the L-shaped connecting frame 721. The slot-in-slot locking block 722 is provided with a locking block limiting hole 723, which matches the top-pressing limiting post 712. The top-pressing of the slot-in-slot locking block 722... The top side is provided with a slope to facilitate pressing the top pressure limiting post 712. In actual use, the three sets of slot-in locking blocks 722 are respectively located on the outside of the limiting side slot 713. Then, the motor frame 4 is rotated, and the three sets of slot-in locking blocks 722 enter the corresponding limiting side slot 713 and press the top pressure limiting post 712 through the slope on their end side. The slot shell 711 deforms until the top pressure limiting post 712 is inserted into the locking block limiting hole 723. The deformation of the slot shell 711 disappears and returns to its original position, realizing the quick installation of the motor frame 4 and the fan cover 3.

[0033] Referring to 7, the panel fastener 6 includes an L-shaped card 62 fixed on the instrument panel bracket 5 and a card fastening hole 61 provided on the door frame 1. The L-shaped card 62 is inserted into the card fastening hole 61. After actual installation, the end of the L-shaped card 62 will be bent after being inserted into the card fastening hole 61 to strengthen the fastening strength and reduce the number of screws used in the door frame 1 and the instrument panel bracket 5.

[0034] The cover fastener 8 consists of a cover clip 81 installed on the outer edge of the bottom of the fan cover 3 and a plate clip hole 82 provided on the upper heat insulation plate 2. The cover clip 81 is a Z-shaped piece.

[0035] Reference Figure 8 A limiting post 9 is installed on the bottom outer side of the fan cover 3, and a horizontal limiting hole 10 is provided on the upper heat insulation plate 2. The limiting post 9 is inserted into the horizontal limiting hole 10 to increase the limiting stability of the fan cover 3 and the upper heat insulation plate 2.

[0036] Reference Figure 9The instrument panel bracket 5 has a panel fixing protrusion 11 at the bottom of the back side, and the door frame 1 has a door frame fixing protrusion 12 at the top of the back side. The door frame fixing protrusion 12, the panel fixing protrusion 11 and the upper heat insulation plate 2 have corresponding screw holes to facilitate the fixing of the upper heat insulation plate 2.

[0037] like Figures 1-9 The fan cover fixing structure shown is the fan cover fixing structure inside the oven. During assembly, the motor shaft on the motor frame 4 extends into the cover through the shaft through hole on the fan cover 3 for the installation of the fan blades. At the same time, the limiting rotating bracket 72 on the motor frame 4 corresponds to the deformation slot 71 on the fan cover 3 and is rotated and snapped into the limiting side slot 713, realizing the quick installation of the fan cover 3 and the motor frame 4, which saves the screw fixing link.

[0038] Then push the cover clip 81 on the fan cover 3 into the clip hole 82. After pushing and clipping, put the limiting post 9 into the horizontal limiting hole 10 to complete the quick installation of the fan cover 3 and the upper heat insulation plate 2. Since the fan cover fixing structure does not include the top plate and side plate of the oven, it will not be described further here. After the top plate is installed, it will further limit the fan cover 3 and the upper heat insulation plate 2 and enhance the stability of the fan cover 3 and the upper heat insulation plate 2 clipping structure.

[0039] Next, the instrument panel bracket 5 is fastened to the panel frame 1 using the panel clip 6, and the heat insulation plate 2 is initially fixed using the gantry fixing protrusion 12 and the panel fixing protrusion 11.

[0040] In the above structure, the door frame 1 and the instrument panel bracket 5, the fan cover 3 and the motor frame 4, and the fan cover 3 and the upper heat insulation plate 2 all adopt the limiting or fixing mode of snap-fit, which greatly reduces the use of screws in the oven assembly process, greatly reduces assembly costs and time, and improves workshop production efficiency.

[0041] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
