Description

Technical Field

[0001] This utility model relates to the field of household appliances, specifically to an oven. Background Technology

[0002] To facilitate the placement of baking trays and racks, oven interiors typically have side supports on the left and right side walls for placing them. However, in existing ovens, these side supports are not adjustable. Once the baking tray or rack is placed inside the oven and positioned on the side supports, its position within the oven is fixed and cannot be adjusted. Because the heating elements are in fixed positions within the oven interior, the temperature distribution within the oven interior is uneven when the heating elements are heating. This prevents the food on the baking tray or rack from being baked in the optimal position to achieve the best cooking results.

[0003] Utility model patent application number CN202210488140.2 discloses an oven, including an inner liner with a shelf inside. The shelf has a connecting structure for detachably connecting the shelf to the inner liner. The shelf includes an upper fixed frame with the connecting structure mounted on it; a lower support frame for mounting or placing a baking tray / rack; and a lifting structure connecting the upper fixed frame and the lower support frame. The lifting structure includes a folding telescopic hinge, which is designed to extend and retract vertically. The oven connects the upper fixed frame and the lower support frame via the folding telescopic hinge. By moving the upper slider on the upper fixed frame, the lower support frame moves up and down, thereby achieving a better baking effect.

[0004] However, the lower support rack of the oven mentioned above can only install one set of baking trays or racks, which limits the amount of food that can be baked at one time and cannot meet the user's needs for large-scale baking. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an oven that can move baking trays or racks up and down while also installing multiple sets of baking trays or racks, so as to solve the problems in the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: an oven, including an inner liner, a side bracket detachably installed inside the inner liner, a movable support plate vertically slidably installed on the side bracket, and a fixed support plate detachably installed on the side bracket; a vertically extending slide rod is fixedly installed on the side bracket, a slide seat matching the slide rod is fixedly installed on the movable support plate, a vertically extending lead screw is rotatably installed on the side bracket, a lead screw nut matching the lead screw is fixedly installed on the movable support plate, and a power component for driving the lead screw to rotate is provided on the inner liner; a clamping plate is fixedly installed on one side of the fixed support plate by fastening bolts, and both the clamping plate and the opposite side of the fixed support plate are provided with arc-shaped grooves for clamping the slide rod.

[0007] As a further improvement, the slide bar is provided with scale lines.

[0008] As a preferred technical solution, the side support includes a base plate and an upper fixed plate located above the base plate. The sliding rod is fixedly installed between the base plate and the upper fixed plate, and the lead screw is rotatably installed between the base plate and the upper fixed plate. A sliding column is vertically slidably installed on the upper fixed plate. A stop block is fixedly installed at the lower end of the sliding column, and a top plate is fixedly installed at the upper end of the sliding column. Vertically extending positioning columns are fixedly installed on the inner sides of the top and bottom walls of the inner liner, and positioning holes for the corresponding positioning columns to pass through are provided on the top plate and the bottom plate, respectively. A vertically extending screw is fixedly installed at the bottom of the top plate, and a nut for pressing downward against the upper fixed plate is screwed onto the screw.

[0009] As a further improvement, a spring is fitted onto the sliding column located between the top plate and the upper fixed plate.

[0010] As a preferred technical solution, the power component includes a motor mounted on the inner liner, the motor's rotating shaft being coaxial with the lead screw, a polygonal prism-shaped insert rod being fixedly mounted on the motor's rotating shaft, the center line of the insert rod coinciding with the axis of the motor's rotating shaft, a connecting seat being fixedly mounted on one end of the lead screw, and the connecting seat having a slot for inserting the insert rod.

[0011] After adopting the above technical solution, the beneficial effects of this utility model are:

[0012] (1) When users need to bake a small amount of ingredients, there is no need to install a fixed support plate on the side bracket. During the baking process, the motors on both sides can drive the corresponding lead screws to rotate synchronously to adjust the height of the two movable support plates and the baking tray or rack so as to accurately control the baking temperature.

[0013] (2) When the oven has been used for a long time, the nut can be rotated in the opposite direction to drive it away from the top of the upper fixed plate. Then the top plate can be pressed down to separate the top plate from the positioning plate above. Then the side bracket can be removed from the inner cavity to clean the oil stains on the side bracket and avoid a large amount of oil stains adhering to the slide rod and screw rod, which would cause the movable support plate to rise and fall unevenly.

[0014] (3) When the user needs to bake a large amount of food, the corresponding number of fixed support plates can be installed on the side brackets on both sides. The user can then insert the baking tray or rack between the two opposite fixed support plates and between the two movable support plates. By cooperating with the fixed support plates and the movable support plates, multiple sets of baking trays or racks can be installed at the same time to meet the user's needs for large-scale baking.

Detailed Implementation

[0022] like Figures 1 to 5 As shown, an oven includes an inner liner 1, which is fixedly installed inside the oven body 2, and a heating element 3 is fixedly installed at the bottom of the inner liner 1.

[0023] The inner liner 1 is equipped with removable side supports 29, with two sets of side supports 29 arranged opposite each other on the left and right sides. Specifically, as follows... Figure 4As shown, the side support 29 includes a base plate 4 and an upper fixed plate 5 located above the base plate 4. A vertically extending slide rod 6 is welded between the base plate 4 and the upper fixed plate 5. Two slide rods 6 are arranged side by side. A vertically extending lead screw 7 is also rotatably installed between the base plate 4 and the upper fixed plate 5 through a bearing. A sliding column 8 is vertically slidably installed on the upper fixed plate 5. Two sliding columns 8 are arranged side by side. A stop block 9 is integrally formed at the lower end of the sliding column 8 to prevent the upper fixed plate 5 from detaching from the sliding column 8. The upper ends of the two sliding columns 8 are fixedly installed on the same top plate 10. The upper end of the sliding column 8 is provided with an external thread and screwed onto the top plate 10.

[0024] To facilitate the assembly and disassembly of the opposite bracket 29, such as Figure 1 and Figure 3 As shown, two positioning plates 11 are respectively provided on the left and right ends of the inner liner 1, which are arranged vertically opposite each other. The two positioning plates 11 are respectively fixed to the inner side of the top wall and bottom wall of the inner liner by bolts. Two positioning posts 12 are respectively welded to the bottom of the upper positioning plate 11 and the top of the lower positioning plate 11, which are arranged in parallel. The positioning posts 12 extend vertically. The top plate 10 and the bottom plate 4 are respectively provided with positioning holes 13 for the corresponding positioning posts 12 to pass through. The bottom of the top plate 10 is respectively welded to the front and rear ends of the vertically extending screw rods 14. The upper fixing plate 5 is provided with clearance holes for the screw rods 14 to pass through. Nuts 15 for pressing the upper fixing plate 5 downward are screwed onto the screw rods 14.

[0025] In addition, to facilitate the installation of the side bracket 29, a spring 16 is fitted on the sliding column 8 located between the top plate 10 and the upper fixed plate 5.

[0026] A movable support plate 17 is vertically slidably mounted on the side bracket 29. A slide seat 18 matching the slide rod 6 is fixedly mounted on the outside of the movable support plate 17 by bolts. A screw nut 19 matching the lead screw 7 is also fixedly mounted on the outside of the movable support plate 17 by bolts. A power component for driving the lead screw 7 to rotate is provided on the inner liner 1. Specifically, the power components include motors 20 and lead screws 7. The two motors 20 are respectively installed on the left and right sides of the bottom of the inner liner 1 by bolts. The rotation shaft of the motor 20 is coaxial with the corresponding lead screw 7. The rotation shaft of the motor 20 extends upward into the inner liner 1 and is integrally formed into a multi-faceted prism-shaped insertion rod 21. The positioning plate 11 located below has a reserved hole for the insertion rod 21 to pass through. The center line of the insertion rod 21 coincides with the axis of the rotation shaft of the motor 20. The middle part of the bottom plate 4 is arched upward. The lower end of the lead screw 7 is rotatably installed on the arched part of the bottom plate 4 through a bearing. The lower end of the lead screw 7 passes downward through the bottom plate and is fixedly installed with a connecting seat 22 by bolts. The bottom of the connecting seat 22 has a slot 23 for the insertion rod 21 to be inserted.

[0027] A fixed support plate 24 can also be detachably installed on the side bracket 29. One or more fixed support plates 24 can be installed according to usage requirements. Figure 3 and Figure 5 As shown, a clamping plate 25 is fixedly installed on the outer side of the fixed support plate 24 by fastening bolts 27. The clamping plate 25 corresponds to the slide rod 6 one by one. Both the clamping plate 25 and the fixed support plate 24 have arc-shaped grooves on their opposite sides for clamping the slide rod 6.

[0028] To facilitate adjusting the fixed support plates 24 on the left and right brackets 29 to the same height, the slide rod 6 is provided with scale lines 26. In addition, to facilitate the installation of baking trays or grills, the inner side of the movable support plate 17 and the inner side of the fixed support plate 24 are respectively provided with front and rear extending mounting slots 28, which can be used to insert baking trays or grills.

[0029] When using this product, if the user needs to bake a small amount of ingredients with precision, the side bracket 29 should be installed first. Specifically, first, overcome the elastic force of the spring 16 and press the top plate 10 downwards, bringing the top plate 10 and the bottom plate 4 closer together, so that the side bracket 29 can be installed between the two corresponding positioning plates 11. After placing the side bracket 29 between the two corresponding positioning plates 11, first, place the bottom plate 4 against the lower positioning plate 11, so that the corresponding positioning post 12 passes through the positioning hole 13 on the bottom plate 4. At the same time, insert the rod 21 on the rotating shaft of the motor 20 into the slot 23 on the lower end connecting seat 22 of the lead screw 7, so that when the motor 20 is running, the lead screw 7 can rotate with the rotating shaft of the motor 20. Then, the top plate 10 is released, the compressed spring 16 extends and pushes the top plate 10 upward, so that the top plate 10 fits against the positioning plate 11 located above. At the same time, the corresponding positioning post 12 passes through the positioning hole 13 on the top plate 10, which plays a preliminary positioning role on the side bracket 29. Finally, the nut 15 is rotated in a specific direction to drive it to move downward along the screw 14 until the nut 15 touches the top of the upper fixing plate 5, so that the top plate 10 cannot move up and down relative to the upper fixing plate 5, and the side bracket 29 cannot be separated from the inner liner 1, thus playing a stable fixing role on the side bracket 29.

[0030] After the side bracket 29 is installed, there is no need to install the fixed support plate 24. First, the motor 20 on one side drives the corresponding lead screw 7 to rotate. The lead screw 7 acts on the lead screw nut 19 and drives the corresponding movable support plate 17 to slide up and down along the slide rod 6, so as to adjust the movable support plates 17 on both sides to the same height. After the movable support plates 17 on both sides are adjusted to the same height, the user can insert the baking tray or rack between the two movable support plates 17 for baking. During the baking process, the motors 20 on both sides drive the corresponding lead screw 7 to rotate synchronously, so as to adjust the height of the two movable support plates 17 and the baking tray or rack, so as to precisely control the baking temperature.

[0031] After the oven has been used for a long time, the nut 15 can be rotated in the opposite direction to move it upward along the screw 14, so that the nut 15 is disengaged from the top of the upper fixed plate 5. Then the top plate 10 can be pressed down to separate the top plate 10 from the positioning plate 11 above. After that, the side bracket 29 can be removed from the inner liner 1 to clean the oil stains on the side bracket 29, so as to avoid a large amount of oil stains adhering to the slide rod 6 and the lead screw 7, which would cause the movable support plate 17 to rise and fall unevenly.

[0032] Additionally, if a user needs to bake a large quantity of food but does not require adjustment of the movable support plate 17, before installing the side brackets 29 into the inner liner 1, first install the corresponding number of fixed support plates 24 on each side of the side brackets 29. Specifically, place the fixed support plates 24 and clamping plates 25 on opposite sides of the slide rod 6, pass the fastening bolts 27 through the holes in the clamping plates 25 and screw them onto the fixed support plates 24. By clamping the slide rod 6 with the clamping plates 25 and the fixed support plates 24, the installation of the fixed support plates 24 is completed. After the fixed support plates 24 are installed, install the side brackets 29 into the inner liner 1, and then adjust the movable support plates 17 on both sides to the same height according to the above steps. Then, the user can insert baking trays or racks between the two opposite fixed support plates 24 and between the two movable support plates 17. By cooperating with the fixed support plates 24 and the movable support plates 17, multiple sets of baking trays or racks can be installed simultaneously to meet the user's needs for large-scale baking.
