Description
Technical Field
[0001] This utility model specifically relates to an automatic heating device for pre-cooked dishes, belonging to the field of pre-cooked dish technology. Background Technology
[0002] Pre-cooked meals, with their "cook and eat immediately" characteristic, have become a popular choice for today's fast-paced lifestyle. These processed, cooked, and quickly frozen ready-made or semi-prepared meals are widely distributed in chain restaurants, convenience stores, and vending machines. Consumers can simply reheat them to enjoy their meals, greatly saving cooking time.
[0003] However, existing heating methods have significant drawbacks in the reheating of pre-prepared meals. Currently, microwave ovens are commonly used in homes and businesses to reheat pre-prepared meals, but the limited internal space of microwave ovens means that only one pre-prepared meal can be heated at a time. If multiple meals need to be heated, they must be done in stages, which undoubtedly increases the overall heating time significantly, contradicting the original intention of pre-prepared meals to be efficient and convenient. In addition, most microwave ovens are placed at a low position, requiring consumers to frequently bend over to retrieve pre-prepared meals, which not only consumes more time and energy but also poses certain safety hazards for the elderly and those with mobility impairments. These problems seriously affect the eating experience and convenience of pre-prepared meals, necessitating innovative heating equipment or technologies to improve the efficiency and convenience of heating pre-prepared meals. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an automatic heating device for pre-cooked dishes that can heat multiple dishes at once and facilitate the handling of the dishes.
[0005] This utility model achieves the above-mentioned objective through the following technical solution: an automatic heating device for pre-prepared dishes, including a heating box, with two doors fixedly connected inside the heating box, and a placement assembly inside the heating box.

[0011] Preferably, the heating chamber is provided with a heating component, which includes a spacer frame fixedly connected to the bottom of the inner cavity of the heating chamber, and a heating wire is fixedly connected inside the spacer frame.
[0012] The above technical solution heats the air inside the heating chamber with heating wires and can also intercept items through the partition frame, thereby reducing the possibility of external items falling onto the heating wires.
[0013] Preferably, a stabilizing component is provided on the outside of the placement frame. The stabilizing component includes four sliding rods fixedly connected to the inside of the heating box. The four sliding rods are divided into two groups. A fixing block is slidably connected to the outside of the sliding rods. The end of the fixing block is fixedly connected to the outside of the heating box.
[0014] The above technical solution uses a sliding rod to support a fixed block, thereby supporting the placement frame.
[0015] Preferably, the stabilizing component further includes a sliding block slidably connected to the outside of the slide rod, and a spring is fixedly connected between the outside of the sliding block and the outside of the fixed block.
[0016] Through the above technical solution, the movement of the placement frame drives the movement of the fixed block, thereby compressing the spring and allowing the sliding block to slide inside the placement frame, thus supporting the placement frame and ensuring its stability.
[0017] Preferably, the outer side of the sliding block is slidably connected to the inside of the placement frame, and the outer side of the sliding block is fixedly connected to the inside of the heating box.
[0018] Through the above technical solution, the sliding block is slidably connected to the placement frame, thereby working with the fixed block and the sliding rod to support the position of the placement frame.
[0019] Preferably, the placement frame passes through the box door and is slidably connected.
[0020] Through the above technical solution, the sliding connection between the placement frame and the box door allows the placement frame to be moved to the outside of the heating box, and the box door can also support the placement frame.
[0021] The beneficial effects of this utility model are as follows: An automatic heating device for pre-prepared dishes uses a motor to drive a first transmission rod to rotate, which in turn drives a drive gear to rotate, which in turn drives a transmission gear to rotate, which in turn drives a second transmission rod to rotate, which in turn drives an auxiliary gear to rotate, which in turn drives a rack to move, which in turn drives a placement frame to move, thereby moving the pre-prepared dishes placed on the placement frame. This allows multiple pre-prepared dishes to be heated at once, thereby reducing the time required to process pre-prepared dishes and improving production efficiency. Furthermore, the placement frame can be moved to the outside of the heating box, thereby moving the pre-prepared dishes to the outside of the heating box, which facilitates the retrieval of the dishes and also makes it easier to place the dishes.

[0040] The movement of the placement frame 11 causes the fixed block 15 to move, thereby compressing the spring 17 and allowing the sliding block 16 to slide inside the placement frame 11, thus supporting the placement frame 11 and ensuring its stability.
[0041] The outer side of the sliding block 16 is slidably connected to the inside of the placement frame 11, and the outer side of the sliding block 16 is fixedly connected to the inside of the heating box 1.
[0042] The sliding block 16 is slidably connected to the placement frame 11, thereby cooperating with the fixing block 15 and the sliding rod 14 to support the position of the placement frame 11.
[0043] The placement frame 11 passes through the box door 2 and is slidably connected.
[0044] By sliding the placement frame 11 to the door 2, the placement frame 11 can be moved to the outside of the heating box 1, and the door 2 can also support the placement frame 11.
[0045] The implementation principle of the automatic heating device for pre-prepared dishes in this application embodiment is as follows: the motor 4 drives the first transmission rod 5 to rotate, which in turn drives the drive gear 6 to rotate, which in turn drives the transmission gear 7 to rotate, which in turn drives the second transmission rod 8 to rotate, which in turn drives the auxiliary gear 9 to rotate, which in turn drives the rack 10 to move, which in turn drives the placement frame 11 to move, thereby moving the pre-prepared dishes placed on the placement frame 11. This allows multiple pre-prepared dishes to be heated at once, thereby reducing the time required to process pre-prepared dishes and improving production efficiency. In addition, the placement frame 11 can be moved to the outside of the heating box 1, thereby moving the pre-prepared dishes to the outside of the heating box 1, which makes it easier to pick up the dishes and also makes it easier to place the dishes.
