Description

Technical Field

[0001] The invention relates to the technical field of skewer grills, and in particular to a skewer grill heating tube and an intelligent smokeless skewer grill formed by the skewer grill heating tube. Background Art

[0002] Skewers refer to all kinds of skewers, such as lamb skewers, seafood, vegetables, etc. When grilling skewers, most of them are placed directly on the grill for grilling. The traditional method is to use charcoal fire or other open flames for grilling. Since only one side of the skewers is in contact with the charcoal fire, the skewers will be heated unevenly, and the skewers need to be turned over repeatedly to prevent them from being burnt, which makes the grilling process time-consuming and laborious. In addition, since the skewers are in direct contact with the charcoal fire, the charcoal fire itself contains a lot of smoke. The grease on the skewers falls into the charcoal fire, which will also produce a lot of smoke. The charcoal fire directly dries the skewers and also produces a lot of smoke. This often leads to a smoky environment during the grilling process, which is increasingly inconsistent with the national environmental protection requirements, and it needs to be shut down, which leads to serious challenges to the skewers as delicious food. Because the skewers are grilled directly on the charcoal fire stove when traditional charcoal fire is used, the charcoal fire stove needs to be open for exhaust or grilling operations, which causes heat dissipation, prolongs the grilling time of the skewers, and is not conducive to energy saving.

[0040] When in use, a skewer assembly is prepared which is assembled with a plurality of skewers. The skewers on the skewer assembly are evenly spaced and arranged in a rectangular shape. A crossbeam is provided on the top of the skewer assembly. The oven intelligent controller 13 synchronously opens the heating films 3 of each heating tube 1 through the skewers baking linkage control module, and at the same time, the oven intelligent controller 13 synchronously opens each motor 12 through the cover opening and closing linkage control module, and the motor 12 drives the driving arm 10 to move (the present invention can be provided with the motor 12 forward and reverse driving, when the motor 12 is driven forward, the motor 12 drives the driving arm 10 to move and realizes that the two flip covers of the flip cover split assembly 7 are opened towards each other; when the motor 12 is driven reversely, the motor 12 drives the driving arm 10 to move and realizes that the two flip covers of the flip cover split assembly 7 are closed towards each other; of course, the motor 12 can be provided with forward and reverse driving, when the motor 12 drives the driving arm 10 to rotate 180 degrees (i.e. 0-180 degrees), the two flip covers of the flip cover split assembly 7 realize the process of opening towards each other, and when the motor 12 drives the driving arm 10 to rotate 180 degrees (i.e. 180-360 degrees), the two flip covers of the flip cover split assembly 7 realize closing towards each other The two flip covers of the flip cover split assembly 7 can be controlled by the rotation angle of the motor 12, the driving arm 10 drives the cover opening and closing driving frame 8 to move and drives the two flip covers of the flip cover split assembly 7 to open towards each other, and the skewer assembly with a plurality of skewers is extended into the heating tube 1 from the middle of the two opened flip covers (which can be achieved by a mechanical arm), and the motor 12 is started to drive the two flip covers of the flip cover split assembly 7 to close towards each other. At this time, the string holes 72 of the two flip covers are just correspondingly combined into string skewers jacks, and the string skewers jacks between the two flip covers are just corresponding to the skewers of the skewer assembly, and the crossbeam rod of the skewer assembly is just located at the top of the flip cover split assembly 7, so that the skewers of the skewer assembly are enclosed in the heating tube 1 for heating and baking.

The temperature sensors can detect the temperature inside the heating tube 1 and transmit the temperature to the temperature monitoring feedback module of the oven intelligent controller 13. The temperature monitoring feedback module controls the switching operation of the heating film 3 of the corresponding heating tube 1 through the skewers baking linkage control module, so as to realize the temperature adjustment of the heating tube 1, which can be done manually or automatically by the oven intelligent controller 13 (for example, a temperature threshold range is set on the oven intelligent controller 13, within which the heating film 3 of the corresponding heating tube 1 is controlled to heat normally; if the temperature is lower than the temperature threshold range, the heating film 3 (also known as microcrystalline electric heating film) of the corresponding heating tube 1 is controlled to accelerate heating; if the temperature is higher than the temperature threshold range, the heating film 3 of the corresponding heating tube 1 is controlled to stop heating, and finally the heating temperature of the heating tube 1 is controlled to be within the set temperature threshold range). Since the skewers assembly is placed in the middle of the heating tube 1, the heating tube 1 can evenly heat both sides of the skewers of the skewers assembly, which also improves the efficiency of skewers baking. At the same time, the skewers of the skewers assembly do not directly contact the inner wall of the heating tube 1, and no fumes will be generated. The present invention uses a microcrystalline electric heating film (also known as a heating film 3) to heat the skewers in the heating tube 1, so that the skewers can be evenly heated and baked. The skewers will not directly contact the heating tube 1, and no fumes will be generated. The skewers baking process is very environmentally friendly. The present invention can be provided with an oil receiving tray drawer at the bottom of the shell 4, and the grease of the skewers directly falls into the oil receiving tray drawer from the bottom tube mouth of the heating tube 1, which will not pollute the ground environment around the skewers; at the same time, the top tube mouth of the heating tube 1 can be rotated and closed by the flip cover plate split assembly 7, which plays a role of heat preservation during the skewers baking process, reduces heat loss, and improves the efficiency of skewers baking.
