[0034] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0035] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. The terms "vertical," "upper," "lower," "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model.

[0036] Reference Figures 1 to 12 As shown, this utility model discloses a telescopic grill, including a baking tray 4, a fire tube 6, and multiple cavities. Each cavity has an opening at its upper end, through which the baking tray 4 is installed. The fire tube 6 is located within each cavity, below the baking tray 4. The cavities have both a retracted / folded state and an extended state. This design allows the grill to be compactly stored when not in use, making it easy to carry and store, while enabling large-capacity grilling during use, meeting the needs of outdoor grilling.

[0037] In this embodiment, the volume of the plurality of cavities gradually decreases from one end to the other. Specifically, the plurality of cavities include a first cavity 1, a second cavity 2, and a third cavity 3 arranged sequentially. 。 The gradually decreasing volume design ensures smooth pulling and nesting between the cavities. When in use, the second cavity 2 and the third cavity 3 are pulled out to one end like drawers, increasing the overall area of ​​the upper opening. This makes the area for baking food three times that of a single cavity, greatly increasing the baking area and meeting the needs of baking large quantities of food, thus improving the user experience. When not in use, the third cavity 3 is stored inside the second cavity 2, and then the second cavity 2 is stored inside the first cavity 1. Compared to the unfolded state, the folded state reduces the volume by 2 / 3, thereby reducing the space occupied during storage and improving the convenience of storage and carrying.

[0038] The third chamber 3 is equipped with a gas regulating valve 7, which is connected to the fire tube 6 through a metal bellows and is used to regulate the gas supply in the fire tube 6 to meet the baking requirements under different conditions. The gas regulating valve 7 adopts existing technology and will not be described in detail.

[0039] Specifically, the tops of multiple cavities are at the same height, and the dimensions of the bottoms or sides of multiple cavities decrease sequentially, so that the openings at the top of multiple cavities are at the same height, improving the stability of the baking tray 4 when placed. The lower ends of the cavities at both ends are respectively provided with supports, that is, the lower end of the first cavity 1 is provided with a first support 8, and the lower end of the third cavity 3 is provided with a second support 9, ensuring the stable support of the oven in the unfolded state, avoiding the risk of the oven tilting or tipping over during grilling, and ensuring the safety of users.

[0040] Furthermore, when fewer people are using it, only the second chamber 2 can be removed from the first chamber 1, while the third chamber 3 remains inside the second chamber 2. This satisfies the user's needs, reduces the heating space, saves energy, and further improves the flexibility of use. To increase stability, a support is installed at the lower end of the second chamber 2 to provide stable support for the oven.

[0041] Furthermore, the first bracket 8 is foldably mounted on the first cavity 1, and the second bracket 9 is foldably mounted on the third cavity 3, further reducing the space occupied during storage.

[0042] In other alternative embodiments, the multiple cavities gradually decrease in size from the center outwards. This allows the cavities to be pulled out from the front and rear ends or the left and right sides, thereby increasing the baking area and improving storage convenience.

[0043] Furthermore, adjacent cavities are connected by a slide rail assembly, which is arranged along the direction of cavity extension and retraction. The slide rail assembly includes matching guide grooves and guide bars, which are respectively set on adjacent cavities. Through a drawer-like extension action, multiple cavities can be unfolded, increasing the usable space of the oven, ensuring the smoothness of the oven's extension and retraction process, and guaranteeing the stability and safety of the structure.

[0044] In this embodiment, the slide rail assembly includes a first guide groove 11, a first guide bar 21, a second guide groove 22, and a second guide bar 31. The first guide groove 11 is disposed on the inner wall of the first cavity 1, the first guide bar 21 is disposed on the outer wall of the second cavity 2, and the first guide bar 21 is inserted into the first guide groove 11. The second guide groove 22 is disposed on the inner wall of the second cavity 2, and the second guide bar 31 is disposed on the outer wall of the third cavity 3, and the second guide bar 31 is inserted into the second guide groove 22, ensuring smooth movement of the guide bar. The first guide groove 11 and the second guide groove 22 are U-shaped grooves with an opening at one end, which limit the guide bar and ensure normal storage. The structure is simple and the operation is convenient.

[0045] The baking tray 4 is a folding baking tray, comprising multiple baking zones. The number of baking zones corresponds to the number of cavities, further improving storage convenience and reducing space occupation. Adjacent baking zones are hinged together by connecting pieces 45. In this embodiment, the baking tray 4 includes a first baking zone 41, a second baking zone 42, and a third baking zone 43. The first baking zone 41 and the second baking zone 42 are respectively hinged to the connecting piece 45 between them, and the second baking zone 42 and the third baking zone 43 are respectively hinged to another connecting piece 45 between them, enabling the baking tray 4 to flexibly change its form in use or storage. After the baking tray 4 is used and cleaned, the first baking zone 41 can be folded above the second baking zone 42, and the third baking zone 43 can be folded below the second baking zone 42. After folding, refer to... Figure 7 As shown. When folded, the overall length of the baking tray 4 is 1 / 3 of that when unfolded, and the unfolded area is 3 times the area when folded. This allows the baking tray 4 to be significantly reduced in size when not in use, making it easy to store with the cavity. At the same time, when in use, it expands the grilling area and improves grilling efficiency.

[0046] Furthermore, the opening is provided with multiple support plates 5, each L-shaped, arranged circumferentially along the opening, and the baking tray 4 is placed on the support plates 5. This ensures the stability of the baking tray 4 during use and guarantees proper food cooking.

[0047] In other embodiments, the number of grilling zones can be varied to accommodate different numbers of people or different types of food, thereby increasing the flexibility and versatility of grilling.

[0048] In other embodiments, multiple independent baking trays 4 can be used, with the area of ​​each baking tray 4 corresponding to the area of ​​the opening on each cavity, which can also increase the area for baking food. When not in use, multiple baking trays 4 can be stacked together to reduce storage volume.

[0049] Furthermore, the baking pan 4 is provided with oil drain holes 44, which are located on the outer side of the baking pan 4. By providing oil drain holes 44 on the edge of the baking pan 4, the oil can be effectively guided out, reducing oil fumes during the grilling process, preventing food from being soaked in oil, improving the cooking taste of the food, and improving the cleanliness of the baking pan 4, thus reducing the amount of cleaning work.

[0050] The fire tube 6 is a telescopic fire tube. The telescopic fire tube uses a multi-section splicing structure, with the number of sections corresponding to the number of cavities. Users can adjust the length of the fire tube 6 according to the size of the grilling area, ensuring even heat distribution and uniform food grilling. In this embodiment, the telescopic fire tube 6 includes three sections: a tail tube 61, a middle tube 62, and a head tube 63. The fire tube 6 adopts a telescopic rod structure similar to an umbrella. When each section of the fire tube 6 is fully extended, a spring-loaded stop pops out to limit its movement. This limiting structure uses existing technology and will not be described in detail further.

[0051] In other embodiments, multiple cavities are equipped with removable fire tubes 6, which can be removed when not in use to heat food.

[0052] In this embodiment, the end of the fire tube 6 is provided with an air inlet 1, and an air cap 64 is provided on the outside of the air inlet 1. The air cap 64 is rotatably mounted on the fire tube 6, and the air cap 64 is provided with an air inlet 2. The air inlet 1 and the air inlet 2 are connected to form an air damper. According to the unfolded state of the cavity, the opening of the air damper is adjusted by rotating the air cap 64 to control the amount of air entering the fire tube 6, thereby adjusting the fire intensity so that the fire intensity can meet the needs of roasting food.

[0053] Furthermore, the side wall of the vent cap 64 is provided with a sliding groove 65, and the locking member 66 passes through the sliding groove 65 and is installed on the head tube 63 of the fire tube 6. The locking member 66 can be a locking screw. When it is necessary to adjust the vent opening, the locking member 66 is loosened appropriately, so that the vent cap 64 rotates along the sliding groove 65 at a certain angle, which improves the convenience of rotation and facilitates the control of the vent opening. After the vent opening is adjusted to a suitable size, the locking member 66 is tightened to fix the vent cap 64, ensuring that the adjusted vent cap 64 will not move easily, thus ensuring safety and stability during the grilling process.

[0054] The usage process of this utility model is as follows:

[0055] When food needs to be grilled, the user unfolds the oven from its folded state by pulling the second chamber 2 and the third chamber 3 outwards along the guide rail assembly until it is fully unfolded. At this time, the grill pan 4 and the fire tube 6 are also in their maximum operating state, ensuring that a sufficient amount of food can be grilled. The user can adjust the folding state of the grill pan 4 and the extension length of the fire tube 6 according to the grilling needs, and can adjust the size of the air vent by rotating the air cap 64, thereby controlling the heat. When the oven is unfolded, the grilling area is increased, ensuring the food is grilled evenly and improving its taste.

[0056] After grilling, clean the grill pan 4, fold the grill pan 4 back to its initial state, and retract the fire tube 6 to its shortest length. Then push the third chamber 3 and the second chamber 2 back into the first chamber 1. Finally, close the air damper 67, and the entire oven will return to its stored state, making it easy to carry and store. This greatly improves the portability and space utilization of the oven, while ensuring the ease of operation and safety during the grilling process.

[0057] 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, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
