[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0027] Please see Figure 1-8This utility model provides a multifunctional warming drawer, including a cabinet 1 and a drawer 2. The cabinet 1 and drawer 2 are slidably connected by a guide rail 3. A heating element (not shown in the figure) is provided on the cabinet 1 or drawer 2. The heating element is a heating element such as a heating tube that can provide a heat source. The heating element can be installed on the cabinet 1 and the bottom of the drawer 2, or only on the cabinet 1, or independently on the bottom of the drawer 2. It should be noted that when the heating element is installed on the cabinet 1, it can be installed in at least one position on the bottom, top, or side panel of the cabinet 1. A shelf 23 is provided inside the drawer 2. Baking trays, grills, or pallets containing food are placed on the shelf 23. The heating element heats the food to keep it warm. The drawer 2 includes a main body 22 and a panel 21. The panel 21 is hinged to the main body 22. A locking member 5 is provided on the main body 22, and a locking part is provided on the panel 21. The locking member 5 cooperates with the locking part to allow the panel 21 to be in a locked state and an unlocked state relative to the main body 22. It should be noted that the panel 21 and the main body 22 can be hinged together using hinges, etc. When the locking element 5 is locked with the locking part, the panel 21 is locked to the main body 22. When the locking element 5 is separated from the locking part, the panel 21 is in the unlocked state relative to the main body 22, and the panel 21 can be flipped downwards relative to the main body 22. For example, when the warming drawer is installed above the oven in a cabinet, it is difficult to pull the drawer 2 out completely due to the limited space in the kitchen or cabinet. In this case, the user can separate the locking element 5 from the locking part, and the panel 21 will flip downwards to form an opening at the front, allowing the user to directly take out the food from the warming drawer. When the user has finished baking large foods such as lamb chops, the user can also unlock the panel 21 from the main body 22, and the panel 21 will flip downwards, forming a shelf that extends outwards from the drawer 22 relative to the cabinet 1, indirectly increasing the usable space of the drawer 2, which can store large or even more food items. When the user needs to clean the drawer 2, the drawer 2 can be pulled out, and then the panel 21 can be unlocked from the main body 22, improving the convenience of cleaning. Users can open panel 21 in any environment, which meets the user's needs in a variety of scenarios and greatly improves the user experience.

[0028] Further, in this embodiment, the main body 22 includes a side plate 221, a bottom plate 222, and a back plate 223. Two side plates 221 are provided, and the two side plates 221 are connected to the back plate 223 in a surrounding manner. The shelf 23 is mounted on the two side plates 221. The panel 21 and the bottom plate 222 are hinged by a damping hinge 4 to prevent excessive impact when the panel 21 is flipped downwards. Specifically, the bottom plate 222 extends outwards to form a mounting boss 2221. The damping hinge 4 includes a bracket 41, a fixed hinge 42, and a movable hinge 43. The bracket 41 is fixed to the mounting boss 2221, the fixed hinge 42 is mounted on the bracket 41, and the movable hinge 43 is mounted on the panel 21. The movable hinge 43 has a pivot, which is rotatably inserted into the fixed hinge 42, allowing the movable hinge 43 to rotate relative to the fixed hinge 42. With this design, the fixed hinge 42 can be located on the side of the side panel 221 near the side wall of the cabinet 1, which can reduce the space occupied by the damping hinge 4 in the drawer 2, thus making the insulated drawer more aesthetically pleasing.

[0029] Furthermore, drawer 2 is equipped with a contact sensor 7, which is located inside cabinet 2. A sealing ring is embedded at the front end of cabinet 1. When drawer 2 is pushed inward, the cooperation between panel 11 and the sealing ring creates a sealed environment inside cabinet 1, preventing heat from escaping. In use, when drawer 2 is closed, contact sensor 7 abuts against the inner wall of cabinet 2. At this time, the controller receives the signal emitted by contact sensor 7 and enables the heating element to be energized. The user can then turn on the heating element using the power switch. When drawer 2 is pulled out partially, contact sensor 7 separates from the inner wall of cabinet 2. Upon receiving the signal, the controller automatically stops the heating element, thus preventing unloaded heating or forgetting to turn off the heating.

[0030] Please see Figure 6-8 The cabinet 1 contains a spring-loaded release mechanism 8 with a swing arm 81 and a roller 82. A positioning element 9 is installed on the drawer 2, with a limiting groove 91. The roller 82 is slidably positioned within the limiting groove 91. When the drawer 2's panel 21 is sealed to the cabinet 1, the roller 82 is engaged in the limiting groove 91, locking the drawer 2 to the cabinet 1. When the user presses the panel 21, the drawer 2 is pushed inwards, compressing the swing arm 81 of the spring-loaded release mechanism. At this time, the roller 82 slides out of the limiting groove 91, and the drawer 2 is also pushed in the opposite direction, moving away from the cabinet 1, thus opening the drawer. When the user pushes the drawer 2 inwards, the positioning element 9 abuts against the swing arm 81. As the drawer 2 continues to move into the cabinet 1, the positioning element 9 compresses the swing arm 81 until the roller 82 is locked in the limiting groove 91, at which point the drawer 2 is locked to the cabinet 1. Users can open the insulated drawer simply by pressing panel 21, making the operation more convenient and effortless.

[0031] Example 1

[0032] Please see Figure 1-2 The multifunctional insulated drawer of Embodiment 1 has a first open state and a second open state. When the user pulls out drawer 2 directly, the insulated drawer is in the first open state. After the user pulls out drawer 2, the locking piece 5 is disengaged from the locking part, and the panel 21 is flipped downwards, at which point the insulated drawer is in the second open state.

[0033] Please see Figure 2-4 The locking element 5 is located on the side panel 221. The locking element 5 includes a mounting base 51, an elastic element 52, and a hook element 53. The hook element 53 is movably mounted on the mounting base 51. One end of the elastic element 52 is fixed to the mounting base 51, and the other end abuts against the hook element 53, allowing the locking element 5 to move up and down on the mounting base 51. The locking part is a slot 211 on the panel 22. When the hook element 53 engages with the slot 211, the panel 211 and the main body 22 are locked. When the user pulls the drawer 2 away from the cabinet 1 and then controls the locking element 5 to move downwards, the hook 53 separates from the slot 211. At this time, the panel 211 and the main body 22 are unlocked, meaning that the panel 211 flips downwards relative to the main body 22. After the user finishes using the warming drawer, they manually push the panel 211 upwards, simultaneously controlling the locking element 5 to move downwards until the hook 53 inserts into the slot 211. Then, they manually control or use other automatic rebound methods to move the locking element 5 upwards, engaging the hook 53 with the slot 211. At this point, the panel 211 is locked to the body 211 and is in a locked state. Through the cooperation of the hook 53 and the slot 211, when the user pulls the drawer 2, the panel 211 is firmly locked to the body 22, preventing the panel 22 from flipping over randomly, and thus preventing food from slipping out during the process of pulling out the drawer 2.

[0034] Furthermore, the latch 53 includes a button 531 and a latch 532. The front end of the latch 532 has a latch portion 5321. The mounting base 51 has a receiving space 511 and an opening. The opening communicates with the receiving space 511. The latch 532 is located within the receiving space 511, and the latch portion 5321 passes through the opening so that it can extend into the latch groove 211. The button 531 is connected to the latch 532 and is located outside the mounting base 51. The user controls the latch 532 to move downward by pressing the button 531, thereby locking or unlocking the panel 21 and the main body 22. In this embodiment, the elastic element 52 is a spring, but it can also be other elastic elements with restoring force, such as a spring sheet, sponge, etc. After the user moves the latch 532 downward by pressing the button 531, releasing the button 531 allows the restoring force of the elastic element 52 to move the latch 532 upward to reset it.

[0035] Furthermore, the mounting base 51 is provided with a protrusion 512, and the hook 532 is provided with a groove 5322. In this embodiment, the groove 5322 is arranged adjacent to the latching part 5321. When the hook 532 separates from the slot 211, the protrusion 512 is embedded in the groove 5322, which limits the hook 532. When the user applies too much force to the button 531, the corresponding elastic element 52 also has a large restoring force, and the protrusion 512 acts as a buffer and stop for the hook 532.

[0036] In order to better fix the elastic element 52 in the mounting base 51, the mounting base 51 is provided with a first positioning post 513 and the hook 53 is provided with a second positioning post 533. One end of the elastic element 52 is sleeved on the first positioning post 513 and the other end is sleeved on the second positioning post 533, so that the hook 53 always keeps in contact with the elastic element 52 during the up and down movement, and avoids the situation where the hook 53 cannot return to its upward position.

[0037] Example 2

[0038] Please see Figure 1 , Figure 2 and Figure 5 The multi-functional insulated drawer of Embodiment 2 has a first open state, a second open state, and a third open state. Embodiment 2 differs from Embodiment 1 in that the locking element is a first magnetic suction element 6, and the locking part is a second magnetic suction element 212. The second magnetic suction element 212 is installed on the panel 21, and the first magnetic suction element 6 and the second magnetic suction element 212 are magnetically attracted to each other, thereby locking the panel 21 to the main body 22. The user only needs to flip the panel 21 downwards, and the first magnetic suction element 6 will separate from the second magnetic suction element 212, thus achieving the third open state. The user can open the panel 21 without pulling out the drawer. Furthermore, the panel 21 and the bottom plate 222 are hinged with a damping hinge, which further improves the situation where the panel 22 flips downwards arbitrarily due to excessive force when pulling out the drawer 2.

[0039] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. For those skilled in the art, various modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
