Description

Technical Field

[0001] This utility model relates to the field of oven technology, specifically to a Teflon-coated clean oven. Background Technology

[0002] Some oven interiors are coated with Teflon, making them easy to clean during use. Additionally, oven trays are also coated with Teflon for easier cleaning.

[0003] Patent document CN108713980B discloses a modular Teflon baking tray. In use, when there are no different types of food, the baking tray is placed directly inside the baking rack, and then the fixing bracket is snapped into the first fixing groove. At this time, a limiting baffle is pressed against the side end of the upper surface of the baking tray. The baking rack limits the horizontal position of the baking tray to prevent horizontal movement, and the limiting baffle limits the vertical position of the baking tray to prevent vertical movement. When there are multiple types of food, a connecting rod is snapped into the connecting groove, and then into the connecting groove of another set of baking trays. When more baking trays need to be added, the snap-fit ​​on the inner connecting rod is snapped into the snap-fit ​​groove, fixing multiple sets of baking trays together for layered baking. However, in this technical solution, when different foods need to be layered, the connecting rod needs to be connected to the baking tray, which is a separate structure, making assembly cumbersome. Meanwhile, existing ovens generally require a tray to rotate the food inside the oven in order to ensure that the food is heated evenly. The existing rotating tray structure is not convenient for layering food. Utility Model Content

[0004] The main purpose of this invention is to provide a Teflon-coated clean oven that allows different foods to be layered and baked in the oven.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A Teflon-coated cleanroom oven includes an oven body with a Teflon coating on its inner liner. The oven body is equipped with multiple trays, each with a four-sided hole at its lower end. A motor is fixed inside the lower end of the oven body, and a four-sided prism that can be inserted into the four-sided hole is concentrically fixed on the output shaft of the motor. A long slot is provided on one side of the upper end of the tray, and a rotating rod is installed in the long slot. The end of the rotating rod away from the axis of the tray is rotatably mounted in the long slot. A slot is provided on the other side of the upper end of the tray.

[0007] Specifically, a second annular groove is concentrically formed at the lower end of the tray, and a first annular groove is formed at the upper end of the bottom plate of the oven body. The first annular groove and the second annular groove are concentric. A rotating ring is provided between the tray and the bottom plate of the oven body. Multiple balls are rotatably connected to the rotating ring. The upper and lower ends of the balls are located on the upper and lower sides of the rotating ring, respectively. The middle part of the balls is rolled and engaged in the rotating ring. The upper and lower ends of the balls roll and contact the groove walls of the second annular groove and the groove walls of the first annular groove, respectively.

[0008] Specifically, the outside of the tray is coated with a Teflon coating.

[0009] Specifically, the length direction of the long groove is parallel to the radial direction of the tray.

[0010] Specifically, the cross-sections of the first and second annular grooves are arc-shaped.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. The design of the long groove, rotating rod, and slot at the top of the tray enables rapid stacking and assembly of multi-layer trays. No separate connecting rods are needed; rotating the rotating rod locks adjacent trays, solving the cumbersome assembly problem caused by component separation in existing technologies. This technical solution allows for layered placement of different foods while maintaining the overall tray rotation function, ensuring even heating of the food.

[0013] 2. The pallet rotation support structure is optimized by cooperating with the rotating ring and ball bearings in the first and second annular grooves. The ball bearings roll within the arc-shaped cross-section of the annular groove, forming multi-point rolling support, reducing friction, significantly improving the stability of pallet rotation, and preventing tilting or jamming caused by uneven load.

[0014] 3. Both the tray and the oven liner are coated with Teflon, featuring a four-sided hole and four-sided prism interlocking structure. The tray is independently removable, and the Teflon coating offers excellent anti-adhesion properties, facilitating thorough cleaning, reducing oil residue, and meeting the high hygiene standards of clean ovens.

[0015] 4. The long slots are arranged radially along the tray, and the positions of the slots and rotating rods match to form a symmetrical locking structure. When stacked, the trays form a self-locking bracket, supporting multi-layer expansion. The number of layers can be flexibly adjusted according to the type and quantity of food, resulting in high space utilization.

[0016] 5. The motor drives the tray to rotate through a rigid connection between the four-sided prism and the four-sided hole, making it easy to pick up the tray. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1: Refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, a Teflon-coated clean oven includes an oven body 1, the inner liner of the oven body 1 is coated with a Teflon coating, and the oven body 1 is equipped with multiple trays 6, the outer sides of which are coated with a Teflon coating.

[0027] The tray 6 has a four-sided hole 11 at the bottom. The oven body 1 has a motor fixed inside the bottom. The output shaft of the motor has a four-sided prism 2 that can be inserted and matched with the four-sided hole 11.

[0028] A long groove 8 is provided on one side of the upper end of the tray 6, and the length direction of the long groove 8 is parallel to the radial direction of the tray 6. A rotating rod 9 is provided in the long groove 8, and the end of the rotating rod 9 away from the axis of the tray 6 is rotatably set in the long groove 8.

[0029] A slot 10 is provided on the other side of the upper end of the tray 6.

[0030] When a single tray 6 is in use, the quadrangular prism 2 is inserted into the quadrangular hole 11 at the bottom of the tray 6, food is placed on the top of the tray 6, and then the oven body 1 can be used to bake the food on the tray 6. When baking the food on the tray 6, the motor is started, and the tray 6 can rotate the food on it due to the cooperation between the quadrangular prism 2 and the quadrangular hole 11.

[0031] The tray 6 is easy to pick up and clean thanks to the interlocking of the quadrangular prism 2 and the quadrangular hole 11.

[0032] When different foods need to be placed in layers, the two trays 6 are positioned one above the other, with the rotating rod 9 of the upper tray 6 corresponding to the slot 10 of the lower tray 6, and the rotating rod 9 of the lower tray 6 corresponding to the slot 10 of the upper tray 6. The rotating rod 9 is rotated so that it is perpendicular to the tray 6 and inserted into the slot 10 on one side. The quadrangular prism 2 is inserted into the quadrangular hole 11 of the lower tray 6. Then, different foods can be placed on the upper part of the two trays 6 respectively.

[0033] like Figure 7 As shown, two trays 6 can be combined to form a rack, and multiple racks can be stacked to hold more different kinds of food.

[0034] Example 2: Based on Example 1, referring to... Figure 1 , Figure 2 and Figure 6 As shown, a second annular groove 7 is concentrically formed at the lower end of the tray 6, and a first annular groove 5 is formed at the upper end of the bottom plate of the oven body 1. The cross-sections of the first annular groove 5 and the second annular groove 7 are arc-shaped. The first annular groove 5 and the second annular groove 7 are concentric. A rotating ring 3 is provided between the tray 6 and the bottom plate of the oven body 1. Multiple ball bearings 4 are rotatably connected to the rotating ring 3. The upper and lower ends of the ball bearings 4 are located on the upper and lower sides of the rotating ring 3, respectively. The middle part of the ball bearings 4 is rolled and engaged in the rotating ring 3. The upper and lower ends of the ball bearings 4 are in rolling contact with the groove wall of the second annular groove 7 and the groove wall of the first annular groove 5, respectively.

[0035] By setting the rotating ring 3 and the ball bearing 4, the ball bearing 4 can cooperate with the first ring groove 5 and the second ring groove 7, thus increasing the support area of ​​the pallet 6 during rotation, thereby improving the stability of the pallet 6 rotation and preventing the pallet 6 from tilting.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
