Description

Technical Field

[0001] This patent belongs to the technical field of kitchen appliances, and particularly refers to an operating panel flipping mechanism. Background Art

[0002] Existing household appliances such as ovens, gas stoves, and disinfection cabinets are all equipped with an operating panel for controlling the operation of the appliances, and on one side wall of the household appliance housing, there is an installation hole adapted to the size of the operating panel. When the operating panel is not in use, it is generally embedded in the installation hole, and the operating surface of the operating panel is connected to the side wall of the housing to form a complete plane, so as to increase the aesthetics of the entire household appliance and prevent the operating panel from protruding and colliding with the outside world, which affects the use. When the operating panel is in use, the operating panel can be rotated through a rotating structure provided at one end of the operating panel, so that the operating panel intersects with the side wall of the housing and faces the user for easy operation by the user.

[0003] The different rotation points around which the operating panel rotates will affect the visible area after the operating panel rotates and the deviation amount between the operating panel and its initial position. Specifically, referring to Figure 1 , Figure 1 where the solid square represents the position of the operating panel when in use, the dashed square represents the position when not in use, and the upper dashed line represents the top position of the installation hole. The operating panel can be rotated around point a on the front side of the operating panel, or around point b at the upper end of the operating panel, or around point c at the rear side of the operating panel through some support structures.

[0004] When the operating panel rotates around point a at the front side of the operating panel, although the entire rotated operating panel can be shown outside the installation opening, sufficient installation space needs to be left on the surface of the household appliance housing to install the rotating structure, which greatly affects the aesthetics of the entire household appliance. When the operating panel rotates around point b and point c at the upper end of the operating panel, although the rotating structure of the operating panel can be effectively hidden, it will affect the visible range of the rotated operating panel, that is, the upper end of the operating panel will be hidden by the housing above the installation opening, resulting in a reduction in the utilization rate of the operating panel and an increase in cost. There is an urgent need for an operating panel flipping mechanism that can completely display the operating panel and does not affect the quality of household appliances. Summary of the Invention

[0005] The purpose of this patent is to provide an operating panel flipping mechanism that can completely display the operating panel and does not affect the quality of household appliances.

[0024] The prominent and beneficial technical effects of this patent compared with the prior art are:

[0025] Through the guiding component arranged in the electrical appliance housing, this patent enables the flipping bracket to rotate around a rotation point located outside the electrical appliance housing, so that the visible range of the flipped panel body is not affected and the appearance of the electrical appliance is not affected, thereby increasing the integrity of the flipped panel body, enhancing the quality, and improving the customer experience.

[0026] This patent forms a semi-closed fan-shaped cavity by connecting the side panels and the connecting panel. It can be used to connect the panel body and place corresponding circuits, and when the panel body is opened, the opening on the electrical appliance housing for installing the operation panel can be closed by the three-dimensional structure formed by the side panels and the connecting panel, increasing the overall quality sense of the product.

[0048] The present patent will be further described below in conjunction with specific embodiments:

[0049] Embodiment 1:

[0050] An operation panel flipping mechanism is installed in a household intelligent stove, as Figure 2 , 3 shown, Figure 2 , 3 The electrical appliance housing 1 on one side of the household intelligent stove is shown, which includes a metal panel, and a plurality of switches 11 for controlling the opening of the stove are arranged on the metal panel, and a flippable operation panel is arranged between the switches 11; CombinedFigure 2 , 3 As shown in 3 , an opening for accommodating the operation panel is formed on the electrical appliance housing 1. When the operation panel is not in use, the operation panel is placed in the opening and connected to the electrical appliance housing 1 around the opening to form a complete surface. When the operation panel is in use, the operation panel flips upward along its upper end and obliquely faces upward towards the user for the user to operate.

[0051] Specifically, as Figure 4 , 5 shown in 5 , the operation panel flipping mechanism in this patent includes a flipping bracket 2, a driving assembly 4, and a guiding assembly 5.

[0052] Combined with Figures 6 - 8 shown in Figures 6 - 8 , the flipping bracket 2 includes side panels 22 on both sides and a connecting panel 23 connected between the two side panels 22 and adapted to the flipping amplitude of the panel main body 3. The side panels 22 are fan-shaped, and both ends of the connecting panel 23 are connected to the arc edges of the side panels 22. After the side panels 22 and the connecting panel 23 are connected, a "U"-shaped flipping bracket 2 is formed. A panel main body 3 is provided on the flipping bracket 2, and the outer edges of the panel main body 3 are respectively connected to one side of the side panels 22 and the connecting panel 23. The panel main body 3 is used to control the operation of the electrical appliance. Generally, it is a liquid crystal display screen and is provided with corresponding circuits. Therefore, in this patent, a semi-closed fan-shaped cavity is formed by connecting the side panels 22 and the connecting panel 23, which can be used to connect the panel main body 23 and place the corresponding circuits, and when the panel main body 3 is opened, the opening on the electrical appliance housing 1 for installing the operation panel can be closed by the three-dimensional structure formed by the side panels 22 and the connecting panel 23, increasing the overall quality feeling of the product.

[0053] The driving assembly 4 includes a driving bracket 41 and a driving motor 42. The driving bracket 41 is arranged inside the electrical appliance housing 1, the driving motor 42 is fixed on the driving bracket 41, the driving motor 42 drives a driving shaft 43, and the other end of the driving shaft 43 is rotatably connected to the flipping bracket 2. As Figures 5 - 7 shown in Figures 5 - 7 , in this embodiment, the driving bracket 41 is "U"-shaped, and it is horizontally arranged at the rear of the flipping bracket 2 and is connected to the inner side of the panel of the electrical appliance housing 1 through its left and right ends.

[0054] The driving bracket 41 is inclined to adapt to the flipping bracket 2 with an arc-shaped panel. At this time, an installation space for installing the driving motor 42 is formed between the driving bracket 41 and the flipping bracket 2. Specifically, as Figure 7 , 9As shown, a first connecting angle iron 44 and a second connecting angle iron 45 are further connected to the driving motor 42. One side surface of the first connecting angle iron 44 is fixed to one side of the driving motor 42 by screws, and the other side surface of the first connecting angle iron 44 is connected to the driving bracket 41 by screws; the second connecting angle iron 45 is connected to one side surface of the first connecting angle iron 44 by screws. Perforations are provided on the first connecting angle iron 44 and the second connecting angle iron 45 and are arranged opposite to each other after the two are connected. The perforations are used for the motor shaft of the driving motor 42 to pass through, and the motor shaft is located on one side of the second connecting angle iron 45. A driving shaft 43 is connected through the motor shaft, and the other end of the driving shaft 43 is rotatably connected to the flipping bracket 2.

[0055] As Figure 9 shown, a first offset portion 451 and a second offset portion 452 are provided on the second connecting angle iron 45. Both the first offset portion 451 and the second offset portion 452 are perpendicular to the second connecting angle iron 45. The driving shaft 43 is arranged between the first offset portion 451 and the second offset portion 452. When the driving motor 42 works, the driving shaft 43 swings between the first offset portion 451 and the second offset portion 452 and is limited by them.

[0056] Further, a transfer bracket 21 rotatably connected to the driving shaft 43 is provided on the flipping bracket 2. A strip-shaped hole 211 is provided on the transfer bracket 21, and one end of the driving shaft 43 is movably arranged in the strip-shaped hole 211. Combining Figures 5 - 8 shown, actually, a transition plate 24 is further provided between the two side panels 22 of the flipping bracket 2. The transfer bracket 21 is installed on the transition plate 24. The transfer bracket 21 is in a "U" shape, and the strip-shaped holes 211 are provided on its left and right side walls. A section of the driving shaft 43 is located inside the transfer bracket 21. By arranging connecting pins on the driving shaft 43 and the transfer bracket 21, one end of the driving shaft 43 can move inside the transfer bracket 21. During work, the driving motor 42 works to drive the driving shaft 43 to swing. The swing of the driving shaft 43 will push the flipping bracket 2 connected to the outer end of the driving shaft 43, causing it to flip, and then drive the panel main body 3 through the folding bracket. Since the flipping bracket 2 makes a rotational movement while the driving bracket 41 is fixed, one end of the driving shaft 43 needs to be rotatably connected to the flipping bracket 2 to adapt to the driving of the flipping bracket 2.

[0057] Further, the guiding component 5 is arranged inside the electrical appliance housing 1 and is used to make the flipping bracket 2 rotate around a rotation point located outside the electrical appliance housing 1. As Figure 5 、 8As shown, the guiding component 5 includes a flipping base 51 disposed inside the electrical appliance housing 1. The flipping base 51 is provided with a guiding cavity 52 having an arc-shaped cross section. The arc-shaped guiding cavity 52 has an axis core 53 located outside the electrical appliance housing 1. The guiding component 5 further includes a guiding portion 54 connected to the flipping bracket 2 and placed inside the guiding cavity 52. In combination with Figure 8 and 11 , as shown in Fig. 12, for the convenience of arranging the arc-shaped guiding cavity 52, the flipping base 51 in this patent includes a first base body 511 and a second base body 512. Corresponding convex surfaces 513 and concave surfaces 514 are respectively provided between the first base body 511 and the second base body 512; specifically, as shown in Figure 10 shown, Figure 10 the first base body 511 is provided with a groove, and the convex surface 513 is arranged inside the groove. Figure 11 The second base body 512 is provided with a convex portion, and the corresponding concave surface 514 is arranged on the convex portion. Corresponding threaded holes are provided on the first base body 511 and the second base body 512. By arranging screws in the threaded holes, the first base body 511 and the second base body 512 are connected, and the convex portion on the second base body 512 is embedded into the groove of the first base body 511, so that the convex surface 513 and the concave surface 514 on the tabletop face each other to form the arc-shaped guiding cavity 52. Threaded holes are also provided on the outer side surface of the first base body 511 for installing one side surface of the first base body 511 on the electrical appliance housing 1, so that the flipping base 51 is arranged inside the electrical appliance housing 1.

[0058] In this patent, the flipping base 51 is located above the opening of the electrical appliance housing 1; correspondingly, the guiding portion 54 is also placed at the upper end of the flipping bracket 2. Its shape is adapted to the guiding cavity 52 and is a sheet body with an arc-shaped cross section. It is integrally formed at the upper end of the flipping bracket 2. Integral formation can reduce the manufacturing difficulty and increase the overall strength. The guiding portion 54 is used to be placed inside the guiding cavity 52, so that the flipping bracket 2 rotates along the arc-shaped guiding cavity 52 and around the axis core 53 of the guiding cavity 52.

[0059] The axis core 53 of the guiding cavity 52 described in this patent can be determined by adjusting the radian of the guiding cavity 52, that is, when the radian of the guiding cavity 52 is larger, the circle where the cross section of the guiding cavity 52 is located is more outward. Relatively, when the radian of the guiding cavity 52 is smaller, the circle where the cross section of the guiding cavity 52 is located is more outward. At this time, since the flipping base 51 is arranged above the opening of the electrical appliance housing 1, correspondingly, the axis core 53 of the guiding cavity 52 is located at the front end above the opening of the electrical appliance housing 1. When the flipping bracket 2 rotates, it will rotate around the axis core 53 located at the front end above the opening of the electrical appliance housing 1.

[0060] In combination with Figure 12As shown, when the panel body 3 is in the non-flipped state, its entirety is located within the opening of the electrical appliance housing 1; after the panel body 3 is flipped, in combination with Figure 13 , 14 As shown, when the panel body 3 is driven by the flipping bracket 2 and rotates around the axis core 53 at the front end of the upper side of the opening of the electrical appliance housing 1, the panel body 3 is located within the opening of the electrical appliance housing 1, so that after the panel body 3 is flipped, the panel body 3 can be completely presented. And since the flipping base 51 and the guiding portion 54 in this patent are both located within the electrical appliance housing 1, the external structure of the electrical appliance will not be affected, so that the entire electrical appliance can be set into a shape that meets the customer's aesthetics, increasing the overall quality of the product.

[0061] In summary, through the guiding assembly 5 disposed within the electrical appliance housing 1 in this patent, the flipping bracket 2 is enabled to rotate around the rotation point located outside the electrical appliance housing 1, so that the visible range of the flipped panel body 3 is not affected, and the external shape of the electrical appliance is not affected, thereby increasing the integrity of the flipped panel body 3, enhancing the quality, and improving the customer experience.

[0062] Further, a boss portion 55 located on the rotation trajectory of the panel body 3 is provided at one end of the flipping base 51. In combination with Figure 10 , 12 , 13, 14, the boss portion 55 is provided at the lower end of the first seat body 511 of the flipping base 51, and a slot 56 is formed between the boss portion 55 and the outer end face of the first seat body 511; the boss portion 55 is located on the rotation trajectory of the panel body 3, and the maximum rotation distance of the panel body 3 can be limited by this boss portion 55, and when the flipping bracket 2 is not rotated, that is, when the panel body 3 is in use, one end of the panel body 3 abuts within the slot 56, and the abutment between the panel body 3 and the slot 56 is used to block the gap for waterproofing; and when the panel body 3 is flipped, the raised boss portion 55 can be used to block the small gap between the panel body 3 and the flipping base 51, increasing the quality sense of the product.

[0063] Further, a plurality of clearance grooves 515 are provided on the convex surface 513 or / and the concave surface 514. As Figure 10 shown, in this embodiment, the clearance grooves 515 are provided on the convex surface 513, and the clearance grooves 515 are used to reduce the contact area between the convex surface 513 or / and the concave surface 514 and the guiding portion 54, thereby reducing the friction between the guiding portion 54 and the convex surface 513 or / and the concave surface 514, making the rotation of the flipping bracket 2 smoother.

[0064] Embodiment 2:

[0065] As Figure 15As shown, most of the structures in this embodiment are the same as those in Embodiment 1. The difference is that the driving brackets 41 in this embodiment are arranged on both sides of the flipping bracket 2. The driving motor 42 is provided on one of the driving brackets 41, and a swing rod 46 is rotatably provided on the other driving bracket 41. The transfer brackets 21 are provided at both ends of the folding bracket. One of the transfer brackets 21 is connected to the driving shaft 43 of the driving motor 42, and the other transfer bracket 21 is connected to the swing rod 46. By driving one side of the flipping bracket 2 with the driving motor 42, the entire flipping bracket 2 is driven to rotate.

[0066] Actually, in Embodiment 1, the driving motor 42 is arranged in the middle of the driving bracket 41 and is connected to the middle of the flipping bracket 2. In comparison, since the structures on the left and right sides of the flipping bracket 2 in Embodiment 2 are different, the forces that the left and right ends of the flipping bracket 2 can withstand are also different. That is, the force that the end of the flipping bracket 2 where the driving motor 42 is provided can withstand is greater than the force that the end without the driving motor 42 can withstand. When the user uses it, they may press the panel main body 3. When pressing the end of the panel main body 3 in Embodiment 2 where there is no driving motor 42, it is very likely that the end of the folding bracket without the driving motor 42 will flip inward, resulting in the panel main body 3 being sunken inward, affecting the overall appearance and reducing the product quality. If the driving motor 42 is connected to the middle of the flipping bracket 2, the forces that the left and right ends of the flipping bracket 2 can withstand are basically the same, and the overall structure is more stable, making it difficult for the folding bracket to rotate when the user presses, thus mostly improving the product quality.

[0067] The above embodiments are only the preferred embodiments of this patent, and do not limit the protection scope of this patent accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this patent should be covered within the protection scope of this patent.
