Description

Technical Field

[0001] This invention relates to the field of barbecue grill technology, specifically a barbecue grill with adjustable air intake. Background Technology

[0002] A barbecue grill is a cooking device that uses a heat source to heat food, such as meat and vegetables. In a narrow sense, it refers to traditional stoves that use a direct heat source, while in a broader sense, it includes grilling options like teppanyaki. Based on the heat source, they are mainly divided into three categories: charcoal, gas, and electric. Charcoal grills rely on burning charcoal to generate heat, gas grills use liquefied petroleum gas or natural gas, and electric grills convert electrical energy into heat. Based on their form, they can be divided into traditional grills that require manual turning and automatic grilling machines; the latter improves efficiency and ensures more even heating. Based on their usage, they are divided into household and commercial grills, with commercial grills having larger capacities and more complex structures.

[0003] A prior art patent application (application number 202023135487.4) describes an adjustable airflow ceramic barbecue grill, comprising a ceramic barbecue grill body, an air inlet box fixed to one end of the body, a controller and a wind speed sensor mounted on the top of the air inlet box, the controller located to one side of the wind speed sensor, and a fan installed inside the air inlet box. Through the controller, wind speed sensor, temperature sensor, first gas cylinder, second oxygen cylinder, and fan, the airflow entering the ceramic barbecue grill body can be better controlled, promoting fuel combustion and improving the device's efficiency. However, it is inconvenient to adjust the height of the grill body, thus making it difficult to control the size of the ventilation holes. Summary of the Invention

[0004] The purpose of this invention is to provide a barbecue grill with adjustable air intake to solve the problem in the prior art that it is inconvenient to adjust the height of the grill body, thus making it inconvenient to control the size of the ventilation holes.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable air intake barbecue grill, comprising a base, a grill body protective cover mounted on the upper side of the base via a lower support, upper supports mounted on the upper sides of both ends of the lower support, a lifting slider mounted on the inner wall of the upper supports via a lead screw, an inner barbecue grill body mounted on one side of the lifting slider via a connecting shaft, a grate and a grill rack sequentially mounted inside the inner barbecue grill body, ventilation holes mounted on both sides of the grate, and an infrared temperature sensor mounted on one side of the upper support via a support rod, capable of non-contact temperature measurement of the upper side of the inner barbecue grill body, and adjusting the size of the ventilation holes according to the detected temperature to facilitate adjustment of the air supply volume of the corresponding inner barbecue grill body, thereby adjusting the temperature of the inner barbecue grill body and achieving the purpose of temperature-controlled grilling.

[0006] Furthermore, the oven body protective cover, the upper support, and the inner oven body for grilling are symmetrically arranged in two sets about the lower support. The oven body protective cover is configured as a ring cover, and the upper support is configured as an inverted U-shaped support.

[0007] Furthermore, the outer wall of the furnace body protective cover is provided with a heat insulation layer, and the heat insulation layer is specifically a rock wool insulation board.

[0008] Furthermore, a fan is provided on one side of the upper end of the furnace body protective cover via an air supply bracket, and the fan is positioned directly opposite a ventilation hole.

[0009] Furthermore, a battery and a controller are provided on the upper side of one end of the base, and the infrared temperature sensor and the control end of the lead screw are electrically connected to the controller.

[0010] Furthermore, a slag discharge plate is hinged to the bottom of the grill body, and the other end of the slag discharge plate is fixedly connected to the bottom wall of the grill body by bolts.

[0011] The adjustment method includes the following steps: S1. The barbecue grill monitors temperature through an infrared temperature sensor. The infrared temperature sensor can receive infrared rays radiated from the surface of the grill body, convert the infrared energy signal into an electrical signal, and then transmit it to the controller on the base. The controller calculates the actual temperature of the grill body. S2. Ventilation holes are provided on both sides of the grate of the grill body, and the grill body is fixed to the lifting slider in the upper support through a connecting shaft; the inner side of the lifting slider is engaged with the lead screw; when the controller receives the temperature signal from the infrared temperature sensor, if the detected temperature is higher than the preset value, it controls the lead screw to rotate in the forward direction, driving the lifting slider to move the grill body upward; at this time, the area of ​​the ventilation holes on the grate exposed outside the grill body protective cover increases, the amount of external air entering the grill increases, the fuel burns more completely, and the heat dissipation is faster, thus achieving cooling; if the detected temperature is lower than the preset value, it controls the lead screw to rotate in the reverse direction, driving the grill body downward; the area of ​​the ventilation holes blocked by the grill body protective cover increases, the air intake decreases, the heat inside the grill is not easily dissipated, and the temperature gradually rises; S3. The outer wall of the furnace body protective cover is equipped with rock wool insulation board. The porous structure of rock wool can block the heat inside the furnace from being conducted outward through the protective cover, reducing heat loss. The upper end of the furnace body protective cover is equipped with a blower fan through the air supply bracket, and the blower fan is directly facing a ventilation hole of the grate. When the ventilation hole is open, the blower fan can actively deliver air into the furnace, enhancing the air intake efficiency. If rapid cooling is required, the blower fan and the ventilation hole opening can be increased to accelerate the entry of cold air and improve the cooling speed.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes an infrared temperature sensor installed on one side of the upper support via a support rod to perform non-contact temperature measurement on the upper side of the grill oven body. Based on the detected temperature, the size of the ventilation holes is adjusted to facilitate the adjustment of the air supply volume of the corresponding grill oven body, thereby regulating the temperature of the grill oven body and achieving the purpose of temperature-controlled grilling.

[0013] 2. The present invention utilizes a lifting slider provided on the inner wall of the upper support via a screw, and a barbecue inner oven body is provided on one side of the lifting slider via a connecting shaft. Ventilation holes are provided on both sides of the grate, so that the lifting slider and the barbecue inner oven body can be adjusted by driving the screw to lift and adjust the depth of the barbecue inner oven body inserted into the oven body protective cover, thereby controlling the size of the ventilation holes, and the adjustment is convenient and quick.

[0014] 3. The present invention utilizes the outer wall of the furnace body protective cover to provide a heat insulation layer, specifically a rock wool insulation board, which enables the exterior of the grill body to be insulated and kept warm, preventing burns during use. At the same time, it has excellent heat insulation performance, reduces heat loss, and facilitates energy saving. Attached Figure Description
