The upper and lower baking trays of the pan-type are connected by a rotating shaft. When fully opened, the upper and lower baking trays are leveled and laid flat on the placement surface, requiring a large placement surface area. Utility Model Content
[0003] In order to overcome the deficiency of a double-layer baking tray in the prior art that a large placement surface area is required, the utility model provides a double-layer baking tray that occupies a small placement surface area.

DETAILED DESCRIPTION
[0042] In the description of this embodiment, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "front", "back", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it cannot be understood as a limitation on the utility model. In addition, if the terms "first", "second", and "third" appear, they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0043] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0044] like Figures 1 to 11 As shown, a double-layer baking tray comprises a base 1, a lower baking tray 2 installed on the base 1, a frame 3 which is flippably arranged on the base 1 and an upper baking tray 4 which is flippably arranged on the frame 3, the frame 3 having a covering state covering the base 1 and a vertical unfolding state unfolded to above the base 1, the upper baking tray 4 having a first use state stored in the frame 3 and a second use state unfolded relative to the frame 3, a first locking member 11 is installed between the base 1 and the frame 3, the first locking member 11 having an unlocking state and a locking state for locking the frame 3 in the vertical unfolding state, when the frame 3 is in the vertical unfolding state and the upper baking tray 4 is in the second use state, the upper baking tray 4 is horizontally arranged above the lower baking tray 2, and a use space is provided between the upper baking tray 4 and the lower baking tray 2.
[0045] In this embodiment, when the double-layer baking tray is needed, the upper baking tray 4 is placed in the second use state, and the frame 3 is placed in the vertical unfolded state, so that the upper baking tray 4 is suspended in the air and is placed only by the base 1, which occupies a small placement surface area and saves space. When storage is needed, the upper baking tray 4 is placed in the first use state, and the frame 3 is placed in the closed state, so that the upper baking tray 4 is stored, which reduces the volume of the double-layer baking tray and facilitates storage.
[0046] Specifically, the first locking member 11 is mounted on the base 1. Figure 8 and Fig. 9As shown, the frame 3 is provided with a first lock hole 31, the first locking member 11 includes a first spring 111 and a first sliding buckle 112, the first sliding buckle 112 is slidably connected to the base 1, and the first spring 111 is connected to the first sliding buckle 112 and the base 1 at both ends, so that one end of the first sliding buckle 112 extends into the first lock hole 31 and locks the frame 3 in a vertical unfolded state, and a part of the structure of the first sliding buckle 112 extends out of the base 1. A part of the structure of the first sliding buckle 112 extends out of the base 1, and the user can press and push the first sliding buckle 112 to switch the first locking member 11 from the locked state to the unlocked state, which is convenient for unlocking the first locking member 11. The first locking member 11 is set on the base 1, and the base 1 does not move during the use of the double-layer baking tray, and the position of the first locking member 11 does not change, which is convenient for user operation.
[0047] It is understandable that the first locking member can also be installed on the frame. For example, in another embodiment, the base is provided with a first locking hole, the first locking member includes a first spring and a first sliding buckle, the first sliding buckle is slidably connected to the frame, and the first spring has two ends respectively connected to the first sliding buckle and the frame, so that one end of the first sliding buckle extends into the first locking hole and locks the frame in a locked state of a vertical unfolded state, and a part of the structure of the first sliding buckle extends out of the frame. The first locking member is arranged on the frame, and the frame is not heated when the double-layer baking tray is in use, and the first locking member is also not heated, which can prevent the user from getting burned when operating.
[0048] Of course, the first locking member may also be other structures. For example, in a certain embodiment, the first locking member is a bolt, and the bolt passes through the base and is threadedly connected to the frame.
[0049] Specifically, Figure 1 As shown, when the frame 3 is in the vertical unfolded state and the upper baking tray 4 is in the second use state, the horizontal projection of the upper baking tray 4 at least partially overlaps with the horizontal projection of the lower baking tray 2. In the second use state, the horizontal projection of the upper baking tray 4 at least partially overlaps with the horizontal projection of the lower baking tray 2, and the space occupied in the unfolding direction of the double-layer baking tray is smaller, reducing the space occupied when both the upper baking tray 4 and the lower baking tray 2 are used; at the same time, the upper baking tray 4 is partially located directly above the base 1, so that the center of gravity of the upper baking tray 4 is close to the center of the base 1, reducing the overturning moment of the upper baking tray 4 relative to the base 1, which is conducive to improving the placement stability of the double-layer baking tray.
[0050] Specifically, Figure 1As shown, a support frame 5 for supporting the upper baking tray 4 is installed between the upper baking tray 4 and the frame 3, and the support frame 5 has a folded state and a supporting state for supporting the upper baking tray 4 in the second use state. The support frame 5 provides additional support to the upper baking tray 4, so that the upper baking tray 4 in the second use state is more stable, and the support frame 5, the upper baking tray 4, and the frame 3 form a triangular structure, which can further increase the stability of the upper baking tray 4 in the second use state. In the first use state, the support frame 5 can also be placed in a folded state, which can reduce the influence of the support frame 5 on the use of the double-layer baking tray in other states.
[0051] Among them, Figure 1 As shown, the support frame 5 includes an upper support rod 51, a lower support rod 52 and a second locking member 53 disposed therebetween, one end of the upper support rod 51 is hinged to the upper baking tray 4, the other end of the upper support rod 51 is hinged to one end of the lower support rod 52, the other end of the lower support rod 52 is hinged to the frame 3, and the second locking member 53 has an unlocking state and a locking state for locking the support frame 5 in the supporting state. The second locking member 53 is used to lock the support frame 5 in the locking state of the supporting state, thereby preventing the relative movement between the upper support rod 51 and the lower support rod 52, so that the upper baking tray 4 in the second use state is more stable.
[0052] Specifically, the second locking member 53 is mounted on the upper support rod 51. Figure 4 and Figure 5 As shown, the lower support rod 52 is provided with a second locking hole 521, and the second locking member 53 includes a second spring 531 and a second sliding buckle 532. The second sliding buckle 532 is slidably connected to the upper support rod 51, and the two ends of the second spring 531 are respectively connected to the second sliding buckle 532 and the upper support rod 51, so that one end of the second sliding buckle 532 extends into the second locking hole 521 and locks the support frame 5 in the supporting state, and a part of the structure of the second sliding buckle 532 extends out of the upper support rod 51. A part of the structure of the second sliding buckle 532 extends out of the upper support rod 51, and the user can press and push the second sliding buckle 532 to switch the second locking member 53 from the locked state to the unlocked state, which is convenient for unlocking the second locking member 53.
[0053] It is understandable that the second locking member can also be installed on the lower support rod. For example, in another embodiment, the upper support rod is provided with a second locking hole, the second locking member includes a second spring and a second sliding buckle, the second sliding buckle is slidably connected to the lower support rod, and the two ends of the second spring are respectively connected to the second sliding buckle and the lower support rod, so that one end of the second sliding buckle extends into the second locking hole and locks the support frame in a supporting state, and a part of the structure of the second sliding buckle extends out of the lower support rod.
[0054] Of course, the second locking member may also be other structures. For example, in a certain embodiment, the first locking member is a bolt, and the bolt passes through the lower support rod and is threadedly connected to the upper support rod.
[0055] Of course, the support frame 5 has other folding structures. Fig.11 As shown, in a certain embodiment, one end of the support frame 5 is hinged to the upper baking tray 4, and the other end of the support frame 5 is slidably connected to the frame 3 through a sliding groove 33 provided on the frame 3. After the support frame 5 switches to a certain state, the frame 3 and the support frame 5 can be locked by a locking member. When the support frame 5 needs to switch its state, the locking member is released.
[0056] Specifically, Figure 3 As shown, the frame 3 also has a planar unfolded state. When the frame 3 is in the planar unfolded state and the upper baking tray 4 is in the first use state, the upper baking tray 4 is horizontally arranged on one side of the lower baking tray 2 .
[0057] Specifically, Figure 1 As shown, the upper baking tray 4 is hinged with the frame 3, and the upper baking tray 4 and the frame 3 are connected with a first elastic member 7, so that the upper baking tray 4 can switch to the second use state under the elastic force of the first elastic member 7; the upper baking tray 4 is provided with a third locking member 41, and the third locking member 41 has an unlocking state and a locking state for locking the upper baking tray 4 in the first use state. The upper baking tray 4 is switched to the second use state under the elastic force of the first elastic member 7 by the elastic force of the elastic member, without manual unfolding, simplifying the operation, and making the double-layer baking tray more convenient to use. The upper baking tray 4 is locked in the locked state of the first use state by the third locking member 41, which can prevent the upper baking tray 4 from moving relative to the frame 3 in the first use state, making the upper baking tray 4 in the first use state more stable, and preventing the user from accidentally changing the state of the upper baking tray 4 in other states.
[0058] In this embodiment, the first elastic member is a torsion spring. Of course, the first elastic member can also be other structures, for example, in a certain embodiment, the first elastic member is a compression spring, one end of the compression spring is connected to the upper baking tray, and the other end of the compression spring is connected to the upper baking tray. When the upper baking tray is in the first use state, the compression spring is compressed, and when the upper baking tray is switched to the second use state, the compression spring is extended.
[0059] Specifically, if Figure 6 and Figure 7As shown, the frame 3 is provided with a third lock hole 32, the third locking member 41 includes a third spring 411 and a third sliding buckle 412, the third sliding buckle 412 is slidably connected to the upper baking tray 4, and the two ends of the third spring 411 are respectively connected to the third sliding buckle 412 and the upper baking tray 4, so that one end of the third sliding buckle 412 extends into the third lock hole 32 and locks the upper baking tray 4 in the first use state, and a part of the structure of the third sliding buckle 412 extends out of the upper baking tray 4. The part of the structure of the third sliding buckle 412 extends out of the upper baking tray 4, and the user can press and push the third sliding buckle 412 to realize the switching of the third locking member 41 from the locked state to the unlocked state, which is convenient for the unlocking of the third locking member 41. The third locking member 41 is set on the upper baking tray, and during the switching process of the upper baking tray 4, the third locking member 41 moves together with the upper baking tray 4, which is convenient for the user to operate.
[0060] It can be understood that, in another embodiment, the third locking member is disposed on the frame.
[0061] Specifically, the upper baking tray is provided with a third locking hole, the third locking member includes a third spring and a third sliding buckle, the third sliding buckle is slidably connected to the frame, and the two ends of the third spring are respectively connected to the third sliding buckle and the frame, so that one end of the third sliding buckle extends into the third locking hole and locks the upper baking tray in the first use state, and a part of the structure of the third sliding buckle extends out of the frame. The third locking member is arranged on the frame, and the frame is not heated when the double-layer baking tray is used, and the third locking member is also not heated, which can prevent the user from being scalded when operating.
[0062] Specifically, Fig.10 As shown, the frame 3 is placed in a vertical unfolded state, and the upper baking tray 4 is placed in a first use state. When the upper baking tray 4 is not needed, the frame 3 is placed in a vertical unfolded state, so that only the lower baking tray 2 can be placed, reducing the placement area requirement. At the same time, the upper baking tray 4 is placed in the first use state, the upper baking tray 4 does not overlap with the lower baking tray 2, and the upper baking tray 4 does not affect the production behavior such as clamping the food on the lower baking tray 2.
[0063] Specifically, Figure 1As shown, a handle 6 is fixed on the upper baking tray 4; the number of the support frames 5 is two, and the two support frames 5 are arranged on opposite sides of the upper baking tray 4. The user can conveniently operate the upper baking tray 4 by grasping the handle 6, and when operating the handle 6 when switching the use state of the upper baking tray 4, there is no need to consider the residual temperature on the upper baking tray 4, which is conducive to improving the operability of the double-layer baking tray; at the same time, the double-layer baking tray can be carried by grasping the handle 6, which can improve the portability of the double-layer baking tray. The two support frames 5 increase the support points of the upper baking tray 4, and the upper baking tray 4 in the second use state is more stable. It can be understood that in another embodiment, the handle is arranged on the frame. The handle is arranged on the frame, so that the double-layer baking tray is more stable.
[0064] Double-layer baking tray action process:
[0065] When using the double-layer: flip the frame 3 to unfold the frame 3 above the base 1, so that the frame 3 is in a vertical unfolded state, and the first locking member 11 is placed in a locked state to lock the frame 3, then flip the upper baking tray and unfold it relative to the frame 3, put the baking tray in the second use state, and put the third locking member 41 in a locked state to lock the upper baking tray, and at the same time unfold the support frame 5, and put the second locking member 53 in a locked state to lock the support frame 5;
[0066] When switching from double-layer use to horizontal unfolding use: unlock the second locking member 53, release the lock of the support frame 5, put the support frame 5 in the folded state, and unlock the third locking member 41, release the lock of the upper baking tray, turn over the upper baking tray, and put the upper baking tray in the first use state; unlock the first locking member 11, turn over the frame 3 to the plane unfolding state, so that the upper baking tray and the lower baking tray are on the same horizontal plane;
[0067] When switching from horizontal deployment to single-layer use: flip the frame 3 to deploy the frame 3 above the base 1, so that the frame 3 is in a vertical deployment state, and put the first locking member 11 in a locked state to lock the frame 3;
[0068] When switching from single-layer use to storage: flip the frame 3, cover the frame 3 with the base 1 so that the frame 3 is in a covered state, and the storage is completed.
