Description

Technical Field

[0001] The utility model relates to the technical field of kitchen equipment, in particular to a lifting device for an embedded kitchen appliance and an embedded steam oven. Background Art

[0002] Modern kitchen appliances are gradually developing towards the direction of intelligence and multi-functionality. As one of the standard configurations of modern kitchens, the embedded steam oven is favored by users due to its many advantages such as space saving, convenient operation, and efficient cooking.

[0003] To ensure the smooth installation of the embedded steam oven, the height of the embedded opening is generally slightly larger than the height of the embedded steam oven. After installing the embedded steam oven into the embedded opening, there is often a relatively large gap between the top of the embedded steam oven and the top surface of the embedded opening space. The height of this gap is generally about 40 mm. This relatively large gap will affect the aesthetics and is prone to accumulating dust, ultimately affecting the user experience. Therefore, a height-adjustable support foot is respectively provided at each of the four corners at the bottom of the embedded steam oven, and the height adjustment method of the support bar is rotation adjustment. When the embedded steam oven is installed into the opening, the installer adjusts the height of the four support feet according to the size of the gap above to adjust the height of the top plate of the embedded steam oven and eliminate the gap.

[0004] However, when the installer needs to adjust the height of the embedded steam oven after installing it into the embedded opening, it is necessary to adjust the four support feet one by one. The installation is complex and time-consuming, and it is easy to cause the risk of imbalance of the four corners when manually judging and adjusting the four support feet one by one, which causes great inconvenience to the installer.

[0063] Embodiment 1

[0064] This embodiment provides a lifting device for an embedded kitchen appliance. This lifting device can be used for height adjustment during the installation of the embedded kitchen appliance, so as to avoid the technical problems of affecting the aesthetics and being prone to dust accumulation caused by too large a gap between the embedded kitchen appliance and the top surface of the embedded opening after the embedded kitchen appliance is installed into the embedded opening, and ensure the user experience.

[0065] In this embodiment, the embedded kitchen appliance is an embedded steam oven. Of course, in other embodiments, the embedded kitchen appliance can also be an embedded baking oven, an embedded dishwasher, an embedded microwave oven or others, which will not be limited here too much.

[0066] Of course, in other embodiments, this lifting device can also be used for height adjustment of other products, not limited to height adjustment of embedded kitchen appliances.

[0067] See Figure 1 and Figure 2 In this embodiment, the lifting device for the embedded kitchen appliance includes a base 1, a top seat 2, a first lifting component 3, a second lifting component 4 and a driving component 5.

[0068] The top seat 2 is arranged at intervals relative to the base 1 in the vertical direction above the base 1, and is used for connecting to the bottom of the embedded kitchen appliance.

[0069] The lower end of the first lifting component 3 is hinged to the base 1, and the upper end is hinged to the top seat 2.

[0070] The second lifting component 4 is arranged opposite to and at intervals from the first lifting component 3 in the first horizontal direction. The lower end of the second lifting component 4 is hinged to the base 1, and the upper end is hinged to the top seat 2.

[0071] The driving component 5 is connected to both the first lifting component 3 and the second lifting component 4, and can drive the first lifting component 3 and the second lifting component 4 to lift synchronously.

[0072] Among them, the base 1 has a square frame structure to ensure the integrity of the lifting device. The top seat 2 includes a first cross beam 21 and a second cross beam 22 arranged opposite to and at intervals from each other in the first horizontal direction. Both the first cross beam 21 and the second cross beam 22 extend in the second horizontal direction. The first horizontal direction and the second horizontal direction are perpendicular to each other. The upper end of the first lifting component 3 is hinged to the first cross beam 21; the upper end of the second lifting component 4 is hinged to the second cross beam 22.

[0073] When the lifting device for an embedded kitchen appliance provided in this embodiment is applied to an embedded kitchen appliance, the first lifting component 3 and the second lifting component 4 are arranged at intervals along the length direction of the embedded kitchen appliance, the top seat 2 is fixedly connected to the bottom plate of the embedded kitchen appliance, and the base 1 is placed on the lower bottom surface of the embedded opening. After the embedded kitchen appliance is initially installed in the embedded opening, the installer controls the first lifting component 3 and the second lifting component 4 to lift synchronously through the driving component, so that the height of the embedded kitchen appliance can be adjusted quickly and conveniently, and the gap between the top of the embedded kitchen appliance and the top surface of the embedded opening space can be eliminated. The driving component controls the first lifting component 3 and the second lifting component 4 to lift synchronously, and can complete the height adjustment of the four corners of the embedded kitchen appliance at one time. While ensuring the balance of the four corners of the embedded kitchen appliance, the installation of the embedded kitchen appliance is made simpler and faster, and the operation difficulty of the installer is reduced.

[0074] Further, the driving component 5 is connected to the bottom plate of the embedded kitchen appliance, so that the driving component 5 can follow the lifting when the embedded kitchen appliance is lifted.

[0075] Further, referring to Figure 1 and Figure 2 , in this embodiment, a movement stroke limiting member 6 is further installed on one of the first lifting component 3 and the second lifting component 4, and the movement stroke limiting member 6 can limit the movement stroke of the lifting device.

[0076] Optionally, the movement stroke limiting member 6 is a travel switch.

[0077] Further, referring to Figure 2 and Figure 3 , in one embodiment, the driving component 5 includes a driving shaft 51, a first lead screw 54 and a second lead screw 56.

[0078] Wherein, the driving shaft 51 can rotate around its own axis, and a first driving bevel gear 52 and a second driving bevel gear 53 are respectively arranged at both ends of the driving shaft 51.

[0079] A first driven bevel gear 55 meshing with the first driving bevel gear 52 is arranged on the first lead screw 54, and the first lead screw 54 is connected to the first lifting component 3 so that when the first lead screw 54 rotates around its own axis, it drives the first lifting component 3 to lift.

[0080] A second driven bevel gear 57 meshing with the second driving bevel gear 53 is arranged on the second lead screw 56, and the second lead screw 56 is connected to the second lifting component 4 so that when the second lead screw 56 rotates around its own axis, it drives the second lifting component 4 to lift.

[0081] With the above-described driving assembly 5, when the driving shaft 51 rotates about its own axis, the first driving bevel gear 52 and the second driving bevel gear 53 rotate synchronously with the driving shaft 51; the first driving bevel gear 52 meshes with the first driven bevel gear 55 to drive the first lead screw 54 to rotate about its own axis; the second driving bevel gear 53 meshes with the second driven bevel gear 57 to drive the second lead screw 56 to rotate about its own axis. Since the first driving bevel gear 52 and the second driving bevel gear 53 rotate synchronously, the first lead screw 54 and the second lead screw 56 can rotate synchronously, realizing the synchronous lifting of the first lifting assembly 3 and the second lifting assembly 4.

[0082] Meanwhile, with the layout of the above-described driving assembly 5, the first lead screw 54, the driving shaft 51, and the second lead screw 56 are arranged in a "U" - shaped structure layout, so as to realize the "U" - shaped structure layout of the first lifting assembly 3, the driving shaft 51, and the second lifting assembly 4. When the lifting device is arranged below the built - in kitchenware, the "U" - shaped structure can avoid the heating position in the middle of the built - in kitchenware, making the structure of the built - in kitchenware more reasonable.

[0083] Furthermore, in one embodiment, the driving assembly 5 further includes a driving member 58, and the output shaft of the driving member 58 is the driving shaft 51.

[0084] Specifically, the driving member 58 is a two - shaft stepper motor.

[0085] Adjusting the rotation direction of the output shaft of the driving member 58 can realize the rising or falling of the top seat 2.

[0086] Specifically, in this embodiment, the driving assembly 5 further includes a mounting seat 59, the driving member 58 is mounted on the mounting seat 59, and the mounting seat 59 can be mounted to the bottom plate of the built - in kitchenware.

[0087] Specifically, referring to Figure 1 、 Figure 4 and Figure 5 , the first lifting assembly 3 includes a first rhombic telescopic structure. The upper intersection point of the first rhombic telescopic structure is hinged to the top seat 2, and the lower intersection point is hinged to the base 1; the first lead screw 54 passes through the two intersection points in the second horizontal direction of the first rhombic telescopic structure. One intersection point is movably connected to the first lead screw 54 and the axial position of this intersection point relative to the first lead screw 54 remains unchanged, and the other intersection point is movably connected to the first lead screw 54 and can move linearly along the first lead screw 54 when the first lead screw 54 rotates about its own axis, so as to enable the first lead screw 54 to drive the height of the first rhombic telescopic structure to be adjusted. The second horizontal direction is perpendicular to the first horizontal direction.

[0088] The first lead screw 54 rotates about its own axis to realize the lifting adjustment of the first rhombic telescopic structure.

[0089] It can be understood that the four intersection points of the first diamond telescopic structure are all hinge structures to ensure that the first diamond telescopic structure can adjust its height.

[0090] Similarly, referring to Figure 1 and Figure 2 , in one embodiment, the second lifting assembly 4 includes a second diamond telescopic structure. The upper intersection point of the second diamond telescopic structure is hinged to the top seat 2, and the lower intersection point is hinged to the base 1; the second lead screw 56 passes through the two intersection points in the second horizontal direction of the second diamond telescopic structure. One of the intersection points is movably connected to the second lead screw 56 and the axial position of this intersection point relative to the second lead screw 56 remains unchanged. The other intersection point is movably connected to the second lead screw 56 and can move linearly along the second lead screw 56 when the second lead screw 56 rotates around its own axis, so that the second lead screw 56 drives the height of the second diamond telescopic structure to be adjusted.

[0091] The second lead screw 56 rotates around its own axis to realize the lifting adjustment of the second diamond telescopic structure.

[0092] It can be understood that the four intersection points of the second diamond telescopic structure are all hinge structures to ensure that the first diamond telescopic structure can adjust its height.

[0093] With the above-mentioned first diamond telescopic structure and second diamond telescopic structure, the first lead screw 54 passes through the two intersection points in the second horizontal direction of the first diamond telescopic structure, and the second lead screw 56 passes through the two intersection points in the second horizontal direction of the second diamond telescopic structure. With such an arrangement, it is fully ensured that the first lifting assembly 3, the drive shaft 51, and the second lifting assembly 4 are arranged in a "U" - shaped structure.

[0094] Exemplarily, referring to Figure 4 , when the first lead screw 54 rotates around its own axis in the first clockwise direction, the intersection point on the left side of the first diamond telescopic structure has an unchanged axial position relative to the second lead screw 56, and the intersection point on the right side is threadedly connected to the second lead screw 56. Therefore, the intersection point on the right side can move axially to the right along the second lead screw 56, thereby reducing the height of the first diamond telescopic structure.

[0095] The first lead screw 54 and the second lead screw 56 rotate in the same first clockwise direction to realize the first diamond telescopic structure and the second diamond telescopic structure to synchronously drive the top seat 2 to move downward.

[0096] Exemplarily, referring to Figure 5 , when the first lead screw 54 rotates around its own axis in the second clockwise direction, the intersection point on the left side of the first diamond telescopic structure has an unchanged axial position relative to the second lead screw 56, and the intersection point on the right side is threadedly connected to the second lead screw 56. Therefore, the intersection point on the right side can move axially to the left along the second lead screw 56, thereby increasing the height of the first diamond telescopic structure.

[0097] The first lead screw 54 and the second lead screw 56 rotate in the same direction along the second clockwise direction, enabling the first diamond telescopic structure and the second diamond telescopic structure to synchronously drive the top seat 2 to move upward. The second clockwise direction is opposite to the first clockwise direction.

[0098] Specifically, in one embodiment, the first lead screw 54 includes a first smooth rod section 541 and a first threaded rod section 542.

[0099] One of the two intersections of the first diamond telescopic structure in the second horizontal direction is rotatably connected to the first smooth rod section 541 and the axial position of this intersection relative to the first lead screw 54 remains unchanged.

[0100] The first smooth rod section 541 and the first threaded rod section 542 are coaxially connected, and the other of the two intersections of the first diamond telescopic structure in the second horizontal direction is threadedly connected to the first threaded rod section 542. It can be understood that an external thread is provided on the outer periphery of the first threaded rod section 542.

[0101] See Figure 4 and Figure 5 , in one embodiment, the first diamond telescopic structure includes a first connecting arm 31, a second connecting arm 32, a third connecting arm 33, and a fourth connecting arm 34.

[0102] Among them, the upper end of the first connecting arm 31 is hinged to the top seat 2, and the lower end is hinged to the first lead screw 54 and the axial position of the lower end relative to the first lead screw 54 remains unchanged.

[0103] The upper end of the second connecting arm 32 is hinged to the first lead screw 54 and the axial position of the upper end relative to the first lead screw 54 remains unchanged, and the lower end is hinged to the base 1.

[0104] The lower end of the third connecting arm 33 is hinged to the base 1, and the upper end is threadedly connected to the first lead screw 54; when the first lead screw 54 rotates around its own axis, the upper end of the third connecting arm 33 can move linearly along the axis of the first lead screw 54.

[0105] The lower end of the fourth connecting arm 34 is threadedly connected to the first lead screw 54, and the upper end is hinged to the top seat 2. When the first lead screw 54 rotates around its own axis, the lower end of the fourth connecting arm 34 can move linearly along the axis of the first lead screw 54.

[0106] It can be understood that the hinged positions of the lower end of the first connecting arm 31 and the upper end of the second connecting arm 32 on the first lead screw 54 are the same. This position is one of the intersections of the first diamond telescopic structure in the second horizontal direction. The arranged positions of the upper end of the third connecting arm 33 and the lower end of the fourth connecting arm 34 on the first lead screw 54 are the same, and this position is the other intersection of the first diamond telescopic structure in the second horizontal direction.

[0107] The upper ends of the first connecting arm 31 and the fourth connecting arm 34 are both hinged to the top seat 2, and this is the upper intersection point of the first rhombus telescopic structure; the lower ends of the second connecting arm 32 and the third connecting arm 33 are both hinged to the base 1, and this is the lower intersection point of the first rhombus telescopic structure.

[0108] Further, referring to Figures 4 - 6 , in one embodiment, the first lifting assembly 3 further includes a first mounting bracket 35 and a bearing 36.

[0109] Wherein, the first lead screw 54 is rotatably arranged through the first mounting bracket 35, and the lower end of the first connecting arm 31 and the upper end of the second connecting arm 32 are both hinged to the first mounting bracket 35.

[0110] The bearing 36 is sleeved on the first lead screw 54 and is located at the intersection of the first connecting arm 31 and the second connecting arm 32, and the bearing 36 is fixedly connected to the first mounting bracket 35.

[0111] The bearing 36 is fixedly connected to the first mounting bracket 35, so as to keep the axial positions of the lower end of the first connecting arm 31 and the upper end of the second connecting arm 32 relative to the first lead screw 54 unchanged.

[0112] The first lead screw 54 is rotatably arranged through the first mounting bracket 35, ensuring that the first lead screw 54 can rotate smoothly around its own axis.

[0113] Specifically, the inner ring of the bearing 36 can rotate, and the outer ring is relatively fixed. The first lead screw 54 passes through the inner ring of the bearing 36, and the inner ring of the bearing 36 can rotate with the first lead screw 54. The outer ring of the bearing 36 is fixed to the first mounting bracket 35.

[0114] Specifically, referring to Figure 5 and Figure 6 , the first mounting bracket 35 includes a first end plate 351 and two first side plates 352. The two first side plates 352 are respectively vertically arranged on the opposite sides of the first end plate 351. The lower end of the first connecting arm 31 is hinged to both of the first side plates 352, and the upper end of the second connecting arm 32 is hinged to both of the first side plates 352. The bearing 36 is located in the space formed by the first end plate 351 and the two first side plates 352 and separates the lower end of the first connecting arm 31 from the first lead screw 54, and separates the upper end of the second connecting arm 32 from the first lead screw 54 to ensure the smooth rotation of the first lead screw 54.

[0115] Further, the outer ring of the bearing 36 is fixed to the first mounting bracket 35 by a plurality of screws. Specifically, the nut of the screw abuts against the end face of the outer ring of the bearing 36 away from the first end plate 351, and the screw is threadedly connected to the first end plate 351.

[0116] Further, in one of the embodiments, in order to realize the threaded connection between the other intersection point of the first diamond telescopic structure in the second horizontal direction and the first lead screw 54 and ensure the hinge connection between the upper end of the third connecting arm 33 and the lower end of the fourth connecting arm 34 at this intersection point, the first lifting assembly 3 further includes a bushing 37 and a second mounting bracket 38.

[0117] The bushing 37 is threaded through the first lead screw 54. The second mounting bracket 38 is arranged through the first lead screw 54 and fixedly connected with the bushing 37. The upper end of the third connecting arm 33 and the lower end of the fourth connecting arm 34 are both hinged to the second mounting bracket 38.

[0118] When the first lead screw 54 rotates around its own axis, the bushing 37 can move linearly along the axis of the first lead screw 54, so that the included angle between the upper end of the third connecting arm 33 and the lower end of the fourth connecting arm 34 hinged on the second mounting bracket 38 changes.

[0119] Specifically, referring to Figure 8 , the second mounting bracket 38 includes a second end plate 381 and two second side plates 382. The two second side plates 382 are respectively vertically arranged at opposite ends of the second end plate 381.

[0120] The upper end of the third connecting arm 33 is hinged to both second side plates 382. The bushing 37 is fixedly connected with the second end plate 381. A perforation for the first lead screw 54 to rotatably pass through is provided on the second end plate 381.

[0121] Further, the bushing 37 is fixedly connected with the second end plate 381 by screws.

[0122] Specifically, in this embodiment, the structure of the second lifting assembly 4 is completely the same as that of the first lifting assembly 3, and the structure of the second lead screw 56 is also completely the same as that of the first lead screw 54. The cooperation between the second lifting assembly 4 and the second lead screw 56 is completely the same as the cooperation between the first lifting assembly 3 and the first lead screw 54, and the cooperation between the second lifting assembly 4 and the second lead screw 56 will not be introduced in detail here.

[0123] Embodiment 2

[0124] This embodiment provides an embedded steam oven.

[0125] Specifically, referring to Figure 9 , the embedded steam oven includes a steam oven body 10, and further includes the lifting device for the embedded kitchenware in Embodiment 1. The top seat 2 of the lifting device is fixedly connected to the bottom of the steam oven body 10, and the driving assembly 5 is fixedly connected to the bottom of the steam oven body 10 through a mounting seat 59.

[0126] More specifically, the top seat 2 of the lifting device is fixedly connected to the bottom plate 101 of the steam oven body 10, and the driving assembly 5 is connected to the bottom plate 101 through the mounting seat 59.

[0127] When the lifting device is applied to an embedded kitchen appliance, the first lifting assembly 3 and the second lifting assembly 4 are arranged at intervals along the length direction of the embedded kitchen appliance, the top seat 2 is fixedly connected to the bottom plate of the embedded kitchen appliance, and the base 1 is placed on the lower bottom surface of the embedded opening. After the embedded kitchen appliance is initially installed in the embedded opening, the installer controls the first lifting assembly 3 and the second lifting assembly 4 to lift and lower synchronously through the driving assembly, so that the height of the embedded kitchen appliance can be adjusted quickly and conveniently, and the gap between the top of the embedded kitchen appliance and the top surface of the embedded opening space can be eliminated. The driving assembly 5 is connected to the bottom plate 101, so that the driving assembly 5 can lift and lower with the steam oven body 10, ensuring that the driving assembly 5 can smoothly drive the lifting of the lifting device.

[0128] The driving assembly controls the first lifting assembly 3 and the second lifting assembly 4 to lift and lower synchronously, which can complete the height adjustment of the four corners of the embedded kitchen appliance at one time. While ensuring the balance of the four corners of the embedded kitchen appliance, the installation of the embedded kitchen appliance is made simpler and faster, reducing the operation difficulty of the installer.

[0129] Exemplarily, the embedded kitchen appliance is an embedded steam oven. The starting device is controlled by the combination key control method of the embedded steam oven. When the after-sales installation puts the embedded steam oven into the embedded opening, touch the time + temperature combination key at the same time to trigger the lifting device mode. When the lifting device is triggered, through the control of the movement stroke limiting member 6, the lifting device defaults to reset to the bottommost position to achieve a balanced state, and the distance of the lifting device's lifting and lowering is adjusted by pressing the "+" and "-" keys to realize the height adjustment of the steam oven body.

[0130] In the specific content of the above specific implementation manner, each technical feature can be combined arbitrarily without contradiction. For the sake of concise description, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features does not exist in contradiction, it should be considered as the scope recorded in this specification.

[0131] The specific content of the above specific implementation manner only expresses several implementation manners of the present invention, and its description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
