Description

Technical Field

[0001] The invention relates to a bamboo skewer transmission mechanism and a barbecue machine, in particular to a bamboo skewer transmission mechanism for a barbecue machine and a barbecue machine using the mechanism. Background Art

[0002] Barbecue grills are commonly used for grilling kebabs, meats, and other items. There are three types of barbecue grills: charcoal grills, gas grills, and electric automatic grills. Gas and electric automatic grills are particularly popular for their smoke-free operation and product-friendly properties. A growing number of barbecue grill types are also available on the market. Patented invention with authorization number CN104958004B, entitled "An Automatic Multifunctional Infrared Smokeless Barbecue," utilizes a chain as a transmission mechanism, equipped with an accessory plate with a central receiving slot for placing skewers. The chain is coordinated with a rack, with the teeth on the rack tilted in the opposite direction of the chain's transmission. This allows the skewers to flip and move forward under the influence of the chain's forward force, the rack's backward friction, and the skewers' own weight. The barbecue time and chain transmission speed can be adjusted based on the type of food being grilled, achieving fully automated barbecue operations and eliminating the time and effort required for manual flipping. Although this type of barbecue machine has many advantages, its transmission parts are easily contaminated by oil stains, especially the receiving grooves on the accessory pieces, which are difficult to clean after being contaminated by oil stains. In addition, the bamboo skewers are prone to slipping after being contaminated, causing the bamboo skewers to slip during rotation, affecting the grilling quality of the skewers.

[0003] In summary, the transmission mechanism of the existing barbecue machine is easily contaminated by oil stains and difficult to clean. Moreover, the bamboo sticks are easy to slip after being contaminated, causing the bamboo sticks to slip during rotation. At the same time, the barbecue machine has the problems of being large in size, heavy in weight and high in energy consumption. Summary of the Invention

The motor is installed on the barbecue machine body, and the motor is keyed to the other end of the connecting shaft.

[0014] Compared with the prior art, the present invention has the following improvements:

[0015] 1. The bamboo skewer transmission mechanism of the present invention utilizes a spring-shaped spiral wire. During actual use, the spring-shaped spiral wire drives the bamboo skewer to move horizontally and rotate simultaneously by self-rotation. It is not easily contaminated by oil stains, and even if contaminated, it will not affect the horizontal movement and rotation of the bamboo skewer. Furthermore, the spring-shaped spiral wire is easy to clean by simply soaking it in water. Furthermore, since it has no blind spots, it is also easy to clean by brushing.

[0016] 2. The spring-shaped spiral wire of the present invention can also clean up impurities (referring to meat residues dropped from the meat skewers) during the rotation process, and the impurities can be automatically discharged from the body as the spring-shaped spiral wire rotates, thereby solving the problem of impurities being continuously roasted at high temperature during the barbecue process, causing odor and affecting the taste of the meat skewers.

[0017] 3. During the rotation process, the spring-shaped spiral wire of the present invention causes the bamboo stick to move and rotate horizontally under the action of the lateral force. Due to its light weight, the driving load is small, thus saving energy.

[0018] 4. The present invention adopts the form of a chain to press the bamboo skewers onto the rack, so that the outer surface of the bamboo skewers can be subjected to a greater driving force for rotation. Even if the meat is not threaded properly, the bamboo skewers can still smoothly complete their rotation while moving horizontally.

[0019] 5. The griller of the present invention adopts a stewing method. When the upper heating device is covered, it is closer to the skewers, which can be cooked quickly. The power of the griller is also reduced from the original 7-9 kilowatts to the current 1-3 kilowatts, saving energy and reducing the size and weight of the griller.

[0020] 6. The barbecue machine of the present invention can automatically release skewers and achieve automatic barbecue. After being placed in the skewer placement area B, the bamboo skewers rotate and move horizontally along the spring-shaped spiral wire, while being subjected to high-temperature barbecue conditions above and below. When the bamboo skewers move horizontally to the end of the spring-shaped spiral wire, they fall directly onto the skewer, allowing the user to remove them and use them. This is convenient and simple to operate. Moreover, the entire barbecue process is smokeless and does not require any other human intervention, preventing the barbecuer from having an uncomfortable barbecue experience caused by traditional open barbecue methods (such as excessive heat during barbecue, especially in summer).
