Description

Technical Field

[0001] The utility model relates to the field of household appliances, in particular to a flap structure, a flip mounting assembly and an electrical appliance. Background Art

[0002] In modern devices, flap structures are often used to implement switching operations, such as the flap for unlocking and opening the panel in a microwave oven. Traditional flap mounting structures usually rely on fixed hinges or fasteners, and these structures are applicable to a variety of devices.

[0003] With the improvement of the appearance requirements for product design and the limitation of the internal space of the device, the defects of traditional flap structures have gradually emerged. Especially on the control box with limited space, large-sized electronic boards occupy most of the space, making the installation and operation of the flap more difficult.

[0004] When the flap is used in a microwave oven, since the material of the front panel of the microwave oven cavity is a sheet metal part with relatively strong rigidity, when the traditional flap structure is installed, it is installed by squeezing with oppositely arranged buckles, which often makes it difficult to install the flap or even causes component damage. Summary of the Utility Model

[0005] Aiming at the above defects, the purpose of the utility model is to provide a flap structure, a flip mounting assembly and an electrical appliance to solve the problem that it is difficult to install the flap.

[0006] To achieve the above object, the utility model adopts the following technical solutions:

[0007] A flap structure includes a flap body. The flap body extends at least two extension parts along a first direction, and the two extension parts are arranged opposite to each other. The opposite surfaces of the two extension parts are defined as the inner sides, and the opposite surfaces of the two extension parts are defined as the outer sides. An inner rotating shaft is arranged on the inner side of one extension part, and an outer rotating shaft is arranged on the outer side of the other extension part. The inner rotating shaft and the outer rotating shaft are coaxially arranged.

[0008] Specifically, the first direction is the vertically upward direction, and the extension parts are vertically upwardly extended at the top of the flap body.

[0009] Specifically, it further includes an interlock pushing part, and the interlock pushing part is integrally formed on the flap body.

[0010] A flip mounting assembly includes a front panel and the flap structure as described above. The front panel is provided with a flap mounting area, and the flap mounting area is provided with flap mounting holes that cooperate with the inner rotating shaft and the outer rotating shaft.

[0011] Specifically, the flap mounting area is further provided with a flap mounting guiding opening.

[0012] Preferably, the flap mounting area is a notch formed on the front panel. The notch extends inward to form two flanges. Each of the flanges is provided with an arc-shaped concave flap mounting guide opening for aligning the left and right sides of the flap body. The flap mounting guide openings are distributed at different heights.

[0013] Specifically, the flap mounting area is provided with a limiting flange. The top surface of the flap body is recessed downward to form a mounting limiting groove, which is arranged close to the extension part. The limiting flange is movably received in the mounting limiting groove.

[0014] Specifically, it further includes an interlocking sub-assembly. The interlocking sub-assembly is mounted on the front panel. The interlocking lever of the interlocking sub-assembly is drivingly connected to the flap structure and is also used to block the flap structure from rotating to the position of the flap mounting guide opening.

[0015] Specifically, the interlocking pushing part of the flap structure is integrally formed at the top of the flap body and is arranged close to the interlocking sub-assembly.

[0016] An electrical appliance uses the flip mounting assembly described above.

[0017] The technical solution provided by the present utility model may include the following beneficial effects:

[0018] By adopting the structure of coaxial and co-directional rotating shafts, the flap body can be easily installed by being pushed in from one side along the flap mounting guide opening, solving the problem that it is difficult to assemble due to the strong rigidity of the installation part, which causes the extrusion installation of two rotating shafts arranged oppositely or in opposite directions.

[0037] The following Figures 1 to 13 describes a flap structure, a flip mounting assembly, and an appliance according to an embodiment of the present utility model.

[0038] A flap structure includes a flap body 1. The flap body 1 extends at least two extension parts along a first direction, and the two extension parts are disposed opposite to each other. The opposite surfaces of the two extension parts are defined as the inner sides, and the opposite surfaces of the two extension parts are defined as the outer sides. One extension part is provided with an inner rotating shaft 111 on the inner side, and the other extension part is provided with an outer rotating shaft 112 on the outer side. The inner rotating shaft 111 and the outer rotating shaft 112 are coaxially arranged.

[0039] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 13, in one embodiment, two rotating shafts 11 are provided on the flap body 1, one is the inner rotating shaft 111 and the other is the outer rotating shaft 112. With the structure that the inner rotating shaft 111 and the outer rotating shaft 112 are coaxial and in the same direction, the flap body 1 can be easily installed by being pushed in from one side, solving the problem that it is difficult to assemble due to the strong rigidity of the installation part, which causes the two rotating shafts 11 arranged oppositely or back to back to be squeezed during installation, and avoiding phenomena such as the compression deformation of the installation part or scratches and cracks on the flap structure.

[0040] Specifically, the first direction is the vertically upward direction, and the top of the flap body 1 extends vertically upward to be provided with the extension part.

[0041] In one embodiment, the flap structure is used to be manually pushed to achieve flipping. The flap body 1 is vertically arranged, and the extension part and the rotating shaft 11 are arranged at the top of the flap body 1. With this structure, the flap body 1 is easy to be pushed and flipped.

[0042] Specifically, it further includes an interlocking pushing part 12, and the interlocking pushing part 12 is integrally formed on the flap body 1.

[0043] Such as Figure 10 , in one embodiment, the flap structure is used for manually unlocking the door of a microwave oven. An interlocking lever 4 and a microswitch are provided in the microwave oven. The interlocking pushing part 12 of the flap body 1 is in partial contact with the interlocking lever 4. When the flap body 1 is pushed to rotate, the interlocking lever 4 can be driven to rotate. After the interlocking lever 4 rotates to a specified angle, the microswitch is triggered to achieve door unlocking.

[0044] A flipping and installing assembly, the flipping and installing assembly includes a front plate 2 and the flap structure as described above. The front plate 2 is provided with a flap installation area, and the flap installation area is provided with flap installation holes 21 that cooperate with the inner rotating shaft 111 and the outer rotating shaft 112.

[0045] Such as Figure 3 And Figure 4 , in one embodiment, the front plate 2 is a panel, the flap installation area is a notch opened on the panel, the notch extends inward to form two flanges, and each of the two flanges is provided with a coaxial flap installation hole 21. The flap body 1 is provided with two rotating shafts 11, and the flap body 1 is installed in the flap installation holes 21 through the rotating shafts 11, and the flap body 1 can rotate around the axis of the rotating shaft 11.

[0046] Specifically, the flap installation area is further provided with a flap installation guiding opening 22.

[0047] Preferably, the flap installation area is a notch opened on the front plate 2, and the notch extends inward to form two flanges, each of the flanges is provided with an arc-shaped concave flap installation guide opening 22, and the flap installation guide opening 22 is used to align the left and right sides of the flap body 1, and the flap installation guide openings 22 are distributed in a high and low position respectively.

[0048] like Figure 5 , Figure 6 , Figure 7 and Figure 8 In one embodiment, the flap installation area is a notch opened on the panel, and the notch extends inward to form two flanges, each of which is provided with an arc-shaped concave flap installation guide opening 22. When installing the flap body 1, it can be first aligned with the flap installation guide opening 22. At this time, the rotating shaft 11 on the flap body 1 can be aligned with the flap installation hole 21, and the flap body 1 can be pushed into the flap installation guide opening 22 to complete the installation of the flap body 1.

[0049] Preferably, two flap installation guide openings 22 are provided, which are used to align the left and right sides of the flap body 1. Specifically, the two flap installation guide openings 22 are located at different flanges, and are respectively distributed one high and one low. When aligning, the top of the flap body 1 can be placed in the flap installation guide opening 22 located at the lower position first, and the interlocking pusher 12 of the flap body 1 is aligned with the flap installation guide opening 22 located at the higher position, so that the flap body 1 can be more smoothly buckled with the front plate 2 at a certain angle of 30°-70°, preferably 45°, and can be pushed into the flap installation hole 21 after alignment.

[0050] Specifically, the flap installation area is provided with a limiting flange 23, and the top surface of the flap body 1 is recessed downward to provide an installation limiting groove 3, the installation limiting groove 3 is arranged close to the extension part, and the limiting flange 23 can be relatively movably accommodated in the installation limiting groove 3.

[0051] like Figure 11 and Figure 12 In one embodiment, the top surface of the flap body 1 is recessed downward to provide an installation limit groove 3. After the flap body 1 is installed on the front plate 2 at a certain angle, it is rotated downward, and the limit flange 23 enters the installation limit groove 3, so that the flap body 1 is restricted by the limit flange 23 and cannot be separated from the flap mounting hole 21 of the front plate 2. Combined with the cooperation between the rotating shaft and the flap mounting hole 21, the axial limit installation of the flap body 1 is realized.

[0052] Specifically, it also includes an interlocking subassembly, which is installed on the front panel 2. The interlocking lever 4 of the interlocking subassembly is drivingly connected to the flap structure, and the interlocking lever 4 is also used to prevent the flap structure from rotating to the position of the flap installation guide port 22.

The interlock pushing portion 12 of the flap body 1 abuts against a part of the interlock lever 4. When the flap body 1 is pushed to rotate, it can drive the interlock lever 4 to rotate. After the interlock lever 4 rotates to a specified angle, the microswitch is triggered to achieve door opening and unlocking. At the same time, due to the existence of the interlock lever 4, the flap body 1 cannot be flipped to the position of the flap installation guiding opening 22, preventing the flap body 1 from disengaging during use.

[0054] Specifically, the interlock pushing portion 12 of the flap structure is integrally formed at the top of the flap body 1, and the interlock pushing portion 12 is arranged close to the interlock sub-assembly.

[0055] As Figure 9 and Figure 10 , in one embodiment, the flap structure is used for manual door opening and unlocking of a microwave oven. The flap body 1 is vertically arranged, the rotating shaft 11 is arranged at the top of the flap body 1, the interlock pushing portion 12 is integrally formed at the top of the flap body 1, the interlock sub-assembly is arranged above the flap body 1, the interlock sub-assembly is an interlock lever 4 and a microswitch, the interlock lever 4 is rotatably fixed above the interlock pushing portion 12 through a cylindrical buckle, the interlock lever 4 abuts against a part of the interlock pushing portion 12, the microswitch is arranged above the interlock lever 4, and there is a gap between the microswitch and the interlock lever 4. With this structure, when the flap body 1 is pushed, the flap body 1 drives the interlock pushing portion 12 to jack up the interlock lever 4 upward. After the interlock lever 4 rotates a certain angle, the microswitch is triggered to achieve manual door opening and unlocking of the microwave oven.
