[0001] This utility model relates to the field of food grilling devices, and in particular to a retractable heating plate and grill. Background Technology

[0002] Barbecue grills are common products for grilling food. Existing barbecue grills vary in structure depending on their shape. However, barbecue grills that use electric heating generally include a grill and a heating element located inside the grill shell. In terms of structure, barbecue grills can generally be divided into single-grill grills, covered barbecue grills, and openable barbecue grills.

[0003] Existing barbecue grills are designed specifically for grilling food in terms of structure and function. They cannot perform other heating modes, such as boiling water or steaming food. Their functions are relatively limited, and they need to be used with other equipment when other usage scenarios are required. Utility Model Content

The movable connecting mechanism is installed between the base and the bottom shell of the barbecue grill. The movable connecting mechanism includes a cooperating horizontal guide rail and a horizontal slide groove. The horizontal guide rail is fixed to the base, and the horizontal slide groove is fixed to the bottom shell.

[0008] In one possible implementation, a vertical floating mechanism is provided between the base and the guide rail assembly, and an elastic support assembly is provided on the heating plate, which supports the heating plate to float elastically in the vertical direction relative to the guide rail assembly.

[0009] In one possible implementation, the vertical floating mechanism includes a mating groove on the base corresponding to the slide groove, a mating post in the mating groove, and a mating hole on the horizontal slide groove corresponding to the mating post.

[0010] In one possible implementation, the side of the mating groove is provided with a limiting step extending laterally, and the base is provided with a limiting slot that cooperates with the limiting step.

[0011] In one possible implementation, the elastic support assembly includes a torsion spring storage hole at the bottom of the base and a support foot on the torsion spring storage hole.

Detailed Implementation

[0017] The following detailed description, in conjunction with specific embodiments and accompanying drawings, clarifies that the described embodiments are only a portion, not all, of the embodiments. All other embodiments obtained by those skilled in the art based on the following embodiments without inventive effort are also within the scope of protection of this utility model.

[0018] It should be understood that if the controllers or control circuits involved in the embodiments are conventional control technologies or units for those skilled in the art, such as the control circuits of the controllers, they can be implemented by those skilled in the art using existing technologies.

[0019] The disclosure of the embodiments provides many different implementations or examples for different solutions to implement this utility model. To simplify the disclosure of this utility model, the structures of components and arrangements of specific examples are described in the embodiments. Of course, these are merely examples and are not intended to limit the utility model. Furthermore, reference numerals and / or reference letters may be repeated in different examples in the embodiments; this repetition is for simplification and clarity and does not in itself indicate a relationship between the various implementations and / or arrangements discussed. In addition, if examples of various specific processes and materials are provided in the embodiments, those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0020] The first embodiment of this utility model provides a retractable heating plate, which includes a heating plate assembly and a movable connecting assembly. The heating plate assembly is installed on the barbecue grill through the movable connecting assembly. The heating plate assembly is retracted along the movable assembly to be integrated with the barbecue grill or extended outside the barbecue grill. When the heating plate is extended outside the barbecue grill, it is in a horizontal state.

[0021] The main purpose of this invention is to provide an improved structure based on the existing structure of a barbecue grill, which can provide an additional horizontal heating surface. This horizontal heating surface can be used to support a heating container and heat the water or food and its mixture inside the container, enabling functions such as boiling water, cooking, and stewing, thus expanding the functionality of the barbecue grill. At the same time, it can be stored away from the barbecue grill when not in use, without occupying the space around the barbecue grill.

[0022] For the purposes described above, in this embodiment, the movable connection component can be a horizontal pivot connection, a vertical pivot connection, or a horizontal lateral pull connection.

[0023] When the movable connecting assembly is connected by a horizontal rotating shaft, the heating plate assembly can be set on the side wall of the barbecue oven. When the heating plate assembly rotates along the horizontal rotating shaft, it switches between a state of being attached to the side wall of the barbecue oven and a horizontal state. When the heating plate assembly is attached to the side wall of the barbecue oven, it forms an integral structure with the side wall of the barbecue oven. When the heating plate assembly is in a horizontal state, it unfolds outside the barbecue oven and is used as an additional heating device.

[0024] When the movable connecting assembly is connected by a vertical rotating shaft, the heating plate assembly can be set at the bottom of the barbecue oven, or a space can be reserved near the bottom of the barbecue oven so that the heating plate assembly can rotate in the horizontal direction when it rotates along the vertical rotating shaft. When the heating plate assembly rotates to the bottom or inside of the barbecue oven, it forms an integrated structure with the barbecue oven. When the heating plate assembly rotates to the outside of the barbecue oven, it is used as an additional heating device.

[0025] When the movable connecting assembly adopts a horizontal side-pull connection, the heating plate assembly can be set at the bottom of the barbecue oven, or in the barbecue oven near the bottom with a reserved space, so that the heating plate assembly can move in the horizontal direction. When the heating plate assembly moves horizontally to the bottom or inside of the barbecue oven, it forms an integrated structure with the barbecue oven. When the heating plate assembly moves horizontally to the outside of the barbecue oven, it is used as an additional heating device.

[0026] The above-mentioned methods for implementing the active connection components can be flexibly implemented according to the shape and structure of the barbecue grill itself, and all can achieve the technical effects of this embodiment.

[0027] Due to the above structure, the retractable heating plate can provide a heating surface outside the barbecue grill during use, which can support and heat the container. In addition to the functions of the barbecue grill itself, it can provide additional working modes such as boiling water and stewing. When not in use, it can be stored in the barbecue grill to form an integrated structure, reducing the occupation of external space and making it easy to place and move. At the same time, when stored in the oven body, it can also heat the bottom of the container placed on it, providing an additional heating mode inside the oven body.

[0028] The second embodiment, based on the horizontal side-pull connection in the first embodiment, further provides a structural solution for a retractable heating plate that can be stored inside the barbecue oven or unfolded outside the barbecue oven through a horizontal side-pull operation.

[0029] like Figures 1-4 As shown, the bottom shell 1 of the barbecue grill in this embodiment has an installation space with a lateral opening. The heating plate assembly for storing the heating plate in this embodiment includes a base 21 and a heating panel 22. The base 21 is horizontally arranged, and the heating panel 22 is installed inside the base 21. The movable connecting mechanism is installed between the base 21 and the bottom shell 1 of the barbecue grill. The movable connecting assembly includes a horizontal guide rail 31 and a horizontal slide groove 32. The horizontal guide rail 31 is connected to the base 21, and the horizontal slide groove 32 is installed on the bottom shell 1.

[0030] The base 21 can be a horizontal frame structure or a structure with an internal space consisting of a bottom surface and side frames. The heating panel 22 can be an independent functional component or a structure in which the internal heating component is encapsulated in the base 21 through the panel.

[0031] With the above structure, the horizontal guide rail 31 is fixed on the base 21 and moves synchronously during sliding. The horizontal slide groove 32 remains stationary with the bottom shell 1, serving as the basis for sliding, thereby enabling the heating plate assembly to move relative to the horizontal and change between the retracted and unfolded states.

[0032] When the barbecue grill is not in use, or when only the grilling function is needed and the external heating plate function is not required, the heating plate assembly 2 is stored inside the bottom shell 1. When external heating is required, the heating plate assembly 2 can be unfolded and used in conjunction with the corresponding switch control.

[0033] The third embodiment of this application further provides a retractable heating plate that can be horizontally pushed and pulled, based on the second embodiment, so as to further achieve other technical effects of the retractable heating plate during use.

[0034] The retractable heating plate in this embodiment is mainly used to solve the weight decoupling problem when the heating plate assembly is pulled out for use. When the barbecue grill needs to control the weight of the food in the grilling container for precise cooking, an electronic weighing device needs to be installed inside the bottom shell of the barbecue grill for weighing, for example... Figure 2 and Figure 4Electronic weighing devices are installed at the four feet on the bottom shell. At this time, the electronic weighing devices weigh the combined weight of the device and the food carried by the entire barbecue grill shell. However, when the heating plate assembly is pulled out and placed on it, the weight changes are easily caused. For example, when boiling water, adding or pouring water will affect the accuracy and stability of the weighing. Therefore, it is necessary to ensure that the weight changes carried by the heating plate assembly are not transmitted to the bottom shell when it is unfolded and in use.

[0035] This embodiment achieves the above objectives in two ways: first, a vertical floating mechanism is provided between the base and the guide rail assembly, allowing the height between the heating plate assembly and the bottom shell to vary within a certain range; second, a support member is provided at the bottom of the heating plate assembly, so that when the heating plate assembly is pulled out to the outside of the bottom shell of the barbecue oven, the support member at the bottom of the heating plate bears the weight of the heating plate assembly and the objects placed on it, without transmitting weight changes to the bottom shell of the barbecue oven. This achieves weight decoupling between the heating plate assembly and the barbecue oven in the unfolded state, and weight changes on the heating plate assembly do not affect the weighing of the food in the barbecue oven; at the same time, the elastic support component at the bottom of the heating plate assembly also needs to be able to elastically retract, so that it can be stored in the bottom shell of the barbecue oven together with the heating plate assembly.

[0036] Regarding the specific structure of the vertical floating mechanism, as follows: Figure 5 As shown, in this embodiment, the vertical floating mechanism includes a mating groove 41 on the base corresponding to the guide rail 31, a mating post 42 in the mating groove 41, and a mating hole 311 on the guide rail 31 corresponding to the mating post.

[0037] Accordingly, in order to prevent the mating post 42 from dislodging from the mating hole 311 when it moves upward, the guide rail 31 is provided with a laterally extending limiting step 312, and the base 21 is provided with a limiting slot 411 that cooperates with the limiting step 312.

[0038] Combination Figure 4 and Figure 10 As shown, in this embodiment, the support member includes a torsion spring storage hole 51 at the bottom of the base and a support foot 52 on the torsion spring storage hole 51. The elastic support base 51 has a horizontal shaft 53, and the support foot 52 is mounted on the horizontal shaft 53. A torsion spring is provided on the horizontal shaft 53, and the support foot 52 is subjected to the elastic force of the torsion spring on the horizontal shaft 53. The support foot 52 has a foot support wheel 54. The foot support wheel 54 is used for corresponding rolling when the support foot 52 slides on a flat surface, avoiding wear and noise caused by hard friction.

[0039] The working principle is explained below in conjunction with the above structure. When the heating plate assembly is housed in the bottom shell 1, the support foot 52 is subjected to upward pressure by the surface of the bottom shell 1. At this time, the support foot 52 rotates and retracts along the horizontal axis. Under the action of elasticity, the support foot 52 pushes the base 21 upward to the highest position defined by the limiting step 312 and the limiting position 411.

[0040] When the heating component is pulled out, the bottom of the support foot 52 loses the pressure applied by the bottom shell 1, and the torsion spring opens the support foot 52. At this time, the support foot 52 is opened by the torsion spring to more than 90° and forms an angle with the elastic support seat 51. The support foot 52 abuts against the contact part 55 of the elastic support seat 51. The support foot 52 forms a stable rigid support for the bottom of the heating plate assembly. At this time, the weight of the heating plate assembly is completely supported by the support foot 52.

[0041] Since the weight of the heating plate assembly is entirely supported by the support foot 52 at this time, the weight change of the heating plate assembly and the heated object placed on it does not affect the bottom shell, and therefore does not exert any effect on the electronic weighing device on the bottom shell. This allows the electronic weighing device to only stably and accurately weigh and control the weight in the barbecue container, thereby decoupling the load-bearing capacity of the heating plate assembly from the weighing capacity of the electronic weighing device after the heating plate assembly is fully pulled out, that is, after the support foot 52 fully supports the heating plate assembly.

[0042] The aforementioned vertical floating mechanism also allows the heating plate assembly to remain in a state where it does not bear weight when it is in its retracted state, supported by the elasticity of the support legs 52. Figure 8 and Figure 9 The highest bit shown, such as Figure 6 and Figure 7 As shown, when the heating plate assembly is in the retracted state and a container is placed on top of it in the barbecue oven for heating, such as a glass pot, the container has a small height error during firing. When the glass pot is installed on the barbecue oven with a supporting and limiting device on the top, the bottom of different glass pots may be at different heights. The vertical floating mechanism can make the bottom of the glass pot always fit in contact with the heating plate, so as to maximize the heating efficiency. After weighing, the height of the heating plate assembly decreases accordingly.

[0043] In the second and third embodiments described above, in order to maintain the stability of the heating plate assembly when it is stored, a self-locking push-button switch is provided between the base and the bottom shell to lock it in the stored state. This self-locking push-button switch is also commonly referred to as a self-locking push-button rebound device, a self-locking beetle rebound device, a beetle module, etc. Structurally, it generally includes a lock body and a lock tongue. Figure 3 and Figure 4As shown, the self-locking push-button switch in this embodiment includes a lock body 61 and a latch 62, wherein the lock body 61 is mounted on the bottom shell 1 and the latch 62 is mounted on the base 21.

[0044] The fourth embodiment also provides a barbecue grill, which is equipped with the retractable heating plate described in the first to third embodiments.

[0045] To facilitate the use of the retractable heating plate structure in the third embodiment and to weigh the food in the grilling area of ​​the grill, a weighing device is provided at the bottom of the grill, outside the coverage area of ​​the retractable heating plate. Figure 2 An electronic weighing device is installed at the foot pad position.

[0046] Preferably, such as Figure 11 As shown, in order to detect the two positions of the heating plate assembly when it is fully retracted and fully extended, and thus control whether the heating plate assembly can work, the bottom shell 1 of the barbecue oven is provided with a detection switch 7 for determining the position of the retractable heating plate. The detection switch can be a contact switch, such as a micro switch, or a signal detection switch, such as a Hall effect contactless sensor switch.

[0047] The above description is only a preferred embodiment of the present utility model and does not limit the scope of disclosure of the present utility model. Any equivalent structural or procedural transformations made based on the description and drawings of the embodiments of the present utility model, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection supported by the embodiments of the present utility model.
