Abstract
Description
Technical Field
[0001] This invention relates to the field of barbecue table technology, specifically to an automatic salt-spraying barbecue table with adjustable grate spacing. Background Technology
[0002] Charcoal-grilled meat, with its unique charred and fragrant flavor, is widely popular in the catering industry and commonly used in daily operations. Currently, most conventional charcoal grill tables on the market have a fixed structure, and the vertical distance between the grill rack and the charcoal inside the grill cannot be adjusted. This presents several practical pain points in actual operation and dining: In the early stages of charcoal burning, the fire is very strong, and the fixed-height grill rack is too close to the charcoal, making the food easily charred, blackened, and bitter; in the later stages of charcoal burning, the fire gradually weakens, and the height of the grill cannot be adjusted to fit, resulting in insufficient heating of the food and overcooking. If the charcoal is frequently replaced to replenish the fire, not only is the operation process cumbersome and disrupts the normal dining rhythm, but it also increases the material and dining costs of the catering establishment. In addition, during the grilling process, the grease dripping from the meat can easily ignite when it comes into contact with the charcoal fire. Direct grilling with open flames not only aggravates the problem of charring the food, but also produces a lot of oil fumes that affect the dining environment. At the same time, there are certain operational safety hazards. The traditional method of manually sprinkling salt to extinguish open flames is inconvenient, the salt is sprayed unevenly, the extinguishing efficiency is low, and there is a risk of burns to the hands. Conventional barbecue tables do not have a dedicated storage space for spare clay stoves, so spare stoves can only be placed randomly, occupying the operation and dining space, and the overall organization is poor. Summary of the Invention
[0003] The purpose of this invention is to provide an automatic salt-spraying barbecue table with adjustable grate spacing to solve the problems mentioned in the background art.

The salt-spraying impeller is covered with an impeller cover, and the end of the auger pipe has a salt inlet that is opposite to the feed inlet of the impeller cover. The top of the auger pipe is connected to a salt-adding funnel.
[0008] Compared with the prior art, the beneficial effects of the present invention are: This adjustable-grate automatic salt-spraying barbecue table features: 1. Adjustable grate spacing to accommodate various ingredients: The tabletop drive rocker drives the threaded rod and support rod, allowing for flexible adjustment of the height of the lifting grate. With the clay oven and charcoal fire positions fixed, the vertical distance between the barbecue grate and the charcoal fire can be freely adjusted, adapting to the grilling requirements of different ingredients such as thick-cut meats, vegetables, and seafood. This effectively prevents the ingredients from burning or being undercooked, enhancing the flexibility of barbecue operation.
[0009] 2. Quickly extinguish open flames and optimize the grilling environment: Equipped with a dedicated salt spraying device, the salt outlet is precisely aimed at the charcoal fire area. When open flames erupt from the charcoal, salt can be quickly sprayed onto the fire to suppress and extinguish it in time, preventing the food from burning and becoming bitter due to direct grilling. At the same time, it reduces the large amount of oil smoke generated by the open flames, improves the dining and operating environment, and reduces the safety hazards caused by open flames. Compared with manual salting, it is easier to operate, the salt is sprayed more evenly, and the fire extinguishing efficiency is higher.
[0010] 3. Rational space utilization and neat storage: The table has a dedicated compartment at the bottom to hold a spare clay stove, making full use of the table's unused space. There is no need to occupy additional tabletop or surrounding space to place spare stoves, making the environment around the barbecue table more organized and making it easier to access and replace spare clay stoves.
[0011] 4. Easy to operate and stable adjustment: The drive lever for lifting the tray is located above the table, making it easy to see and allowing diners to operate it themselves without the need for staff. The support rod and slide rail slide together, and the threaded transmission ensures a smooth and non-deviation-prone lifting process. The height adjustment is precise and controllable, without any jamming or shaking. The structure is simple and requires no professional maintenance.
[0012] 5. The salt spraying mechanism is highly practical and easy to maintain: The auger pipe of the salt spraying mechanism, combined with the salt-adding funnel, makes salt replenishment simple and requires no disassembly; the impeller cover can constrain the direction of salt spraying, preventing salt from splashing and contaminating the tabletop; the overall structure is compact and does not occupy core dining space, making it suitable for the long-term, high-frequency use needs of catering establishments.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.
[0016] Please see Figure 1-6 The present invention provides a technical solution: An adjustable grate automatic salt spraying barbecue table includes a table body 1, which serves as the main support and provides a stable operating platform for barbecue operations. A grill trough 2 is provided on the top of the table body 1. At the same time, a slide rail 11 and a groove 12 are respectively provided on the table surface of the table body 1 near the corresponding position of the grill trough 2. The grill trough 2 provides a dedicated space for the clay oven 4 and can limit and fix the clay oven 4 to ensure the stability of the clay oven 4 during charcoal grilling. The slide rail 11 is used to guide the movement in conjunction with the lifting component. The groove 12 can be used to assist in storage or adapt to the installation of components and optimize the table surface space layout.
[0017] The oven trough 2 is used to accommodate the clay oven 4. A lifting grate 3 is installed at the opening of the oven trough 2. The lifting grate 3 is used to directly support the grill rack and is arranged through the surface of the table body 1. After the clay oven 4 is placed in place, the position of the charcoal inside remains fixed. There is no need to adjust the position of the charcoal. Only the height of the lifting grate 3 needs to be adjusted according to the grilling requirements and the amount of heat required for different ingredients. This changes the vertical distance between the grill rack and the charcoal below, allowing for flexible control of the distance between the rack and the charcoal. This enables precise control of the heat received by the grilled meat and prevents the food from burning or being undercooked.
[0018] A salt spraying mechanism 5 is fixedly installed on the table body 1, adjacent to the inner edge of the oven trough 2. The salt outlet of the salt spraying mechanism 5 is precisely directed towards the charcoal fire area inside the oven trough 2. It is mainly used to spray salt onto the open flame when flames leap up or the open flame is too high during the charcoal burning process. The salt helps to quickly suppress and extinguish the open flame, preventing the food from burning, becoming bitter, or turning black due to direct grilling. At the same time, it reduces excessive oil fumes caused by the open flame, avoids safety hazards in catering operations, maintains a stable state of constant temperature grilling, ensures the taste of the grilled meat and the safety of the grilling operation, and solves the industry pain point of the difficulty in quickly dealing with open flames on traditional charcoal grill tables.
[0019] The bottom of the table body 1 is provided with a special interlayer for placing a spare clay stove 4, which can realize the storage of the clay stove 4, make full use of the idle space at the bottom of the table body 1, and improve the overall practicality of the barbecue table.
[0020] Specifically, a slide rail 11 is provided on the tabletop of the table body 1. The lifting grill support 3 specifically includes a support ring 34, which is a ring-shaped support structure that can stably fit and support the bottom edge of the grill, ensuring that the grill is placed stably. One end of the support ring 34 is fixedly connected to a support rod 33, which is slidably connected to the slide rail 11. The slide rail 11 guides and limits the lifting movement of the support rod 33, ensuring a smooth and non-deviation-free lifting process. The support rod 33 is located away from the support ring 34. One end is threadedly connected to the threaded rod 32, which is installed inside the table body 1, i.e., in the interlayer, and can rotate freely relative to the table body 1. The top end of the threaded rod 32 is connected to a drive rocker 31, which is placed above the table. The operator can directly rotate the drive rocker 31 on the table to drive the threaded rod 32 to rotate synchronously. Through the threaded transmission, the support rod 33 is driven to move up and down along the slide rail 11, ultimately realizing the height adjustment of the support ring 34 and the barbecue rack. The operation is simple and the adjustment accuracy is controllable.
[0021] Alternatively, a small motor can be used to drive the threaded rod 3 to rotate, and then a control button for the small motor can be set on the desktop.
[0022] The salt spraying mechanism 5 is integrally transferred and installed at a preset position on the table. It mainly consists of a salt-spreading impeller 55, an impeller cover 54, an auger pipe 51, and a salt-adding funnel 53. The salt-spreading impeller 55 is the core actuating component. It generates centrifugal force through rotation to evenly throw salt onto the open flame area of the charcoal fire, achieving the purpose of rapid fire extinguishing. The outer side of the salt-spreading impeller 55 is equipped with a sealed impeller cover 54. The impeller cover 54 protects the high-speed rotating salt-spreading impeller 55 from splashing salt out of the water. On the other hand, it can effectively constrain the direction of salt spraying, ensuring that the salt falls accurately onto the open flame of the charcoal fire, thereby improving the efficiency of fire extinguishing. The auger pipe 51 is a dedicated salt conveying component, with a salt inlet 52 at its end. The salt inlet 52 is precisely aligned with the feed inlet of the impeller cover 54, ensuring that the salt in the auger pipe 51 can be smoothly conveyed into the impeller cover 54, providing a continuous and stable supply to the salt-spreading impeller 55 and ensuring a smooth and effective fire extinguishing operation. The auger pipe 51 is placed in the groove 12, and the top of the auger pipe 51 is connected to a flared salt-adding funnel 53, which is slightly higher than the tabletop and will not obstruct dining. This allows operators to quickly replenish salt into the auger pipe 51 without disassembling other parts, making the replenishment operation convenient and efficient, and ensuring the continuous and normal operation of the salt spraying mechanism.
