Abstract
Description
Technical Field
[0001] This utility model relates to a barbecue device, and more specifically, to a temperature-controlled lifting barbecue device. Background Technology
[0002] There are many types of barbecue equipment on the market, and charcoal grills are an ideal choice for camping and outdoor barbecue activities. Charcoal grills typically have a tray for holding charcoal or bamboo charcoal as fuel and a grill for placing food. They use the heat generated by burning charcoal to grill food. Compared with other types of grills, charcoal grills have two major advantages: firstly, their portable design makes them easy to carry and move; secondly, they are equipped with adjustable vents, making it easy to control the burning speed and temperature of the charcoal. Both of these advantages are achieved based on the adjustable tray. Although existing grills have solutions for manually adjusting the tray, in actual use, it is difficult to ensure that the heat is at the right position for the food. Moreover, manual adjustment can easily lead to confusion and burning of the food. Therefore, a temperature-controlled lifting grill device is needed. This device can automatically adjust the position of the tray according to the temperature at the grill, thereby controlling the temperature at the food and preventing it from burning.
[0003] For the reasons mentioned above, the problem addressed in this application is how to automatically adjust the position of the tray based on the temperature at the grill. Utility Model Content
[0004] To address the shortcomings of existing technologies, a temperature-controlled lifting grilling device is provided. This device can automatically adjust the position of the tray according to the temperature at the grill, thereby controlling the temperature of the food and preventing it from burning.
[0005] To achieve the above objectives, the following technical solution is provided: a temperature-controlled lifting barbecue device, including a support, a grill, a tray, a temperature sensor, and a lifting assembly. The grill is installed on the top of the support, the temperature sensor is fixedly connected to the inside of the grill, the tray is located below the grill, and the tray and the grill are connected by the lifting assembly. The lifting assembly includes a driver, which is fixedly connected to the grill and is used to receive signals from the temperature sensor to drive the tray to lift.
[0006] In summary, the above technical solution has the following beneficial effects: The support mainly functions to stabilize the grill and can suspend the tray in the air, leaving a certain space between it and the ground, which facilitates the adjustment of the tray position. Therefore, the support can be sleeved on the grill or the support and the grill can be integrally formed. Since the food is in direct contact with the grill, the control of the heat is concentrated at the grill. Therefore, by detecting the temperature sensor, when the temperature at the grill is too high or too low, the driver receives the signal from the temperature sensor and controls the lifting component after processing. Since the tray and the grill are connected by the lifting component, the distance between the tray and the grill can be controlled by the lifting component, thereby indirectly controlling the temperature at the grill.
[0007] This utility model is designed based on a charcoal grill. While maintaining the portability of a charcoal grill, common charcoal grills involve placing food on the grill rack and controlling the heat by adding or removing fuel on a tray. However, the fuel is usually solid alcohol or charcoal, which means that the fuel cannot be removed when the heat needs to be reduced, making it difficult to control the heat. To solve this problem, existing technologies usually design a closed fuel chamber and multiple air vents on the fuel chamber. When the air vents are open, they can increase air circulation and provide more oxygen for combustion, making the fire stronger. When the air vents are closed, the flame will weaken due to insufficient oxygen. However, in actual use, it has been found that when the lid is closed for grilling, the air vents should not be completely closed. A gap should be left to prevent the charcoal from going out due to lack of oxygen. Therefore, users need to pay more attention to the fuel, which means that users need to pay attention to both the fuel and the food at the same time, which can easily lead to problems such as food burning. In addition, the addition of the fuel chamber adds extra components to the grilling device, reducing portability.
[0008] To address this issue, a temperature sensor is placed inside the grill rack to reduce the error between the detected temperature and the actual temperature of the food. Multiple temperature sensors can be used to further reduce this error and enable real-time temperature monitoring. This allows the lifting mechanism to quickly adjust the distance between the tray and the grill rack, eliminating the need for manual adjustments and avoiding issues caused by the gas vents. Users can then focus solely on the food, as the fuel burns directly in contact with it, eliminating the need for additional components to set up the fuel chamber and enhancing the overall portability of the grill.
[0009] This invention uses a temperature sensor to detect the actual temperature near the grill, and a driver processes the signal from the temperature sensor to control the operation of the entire lifting assembly. This controls the grill and tray to move closer or further apart, automatically adjusting the position of the tray according to the temperature at the grill, thereby controlling the temperature of the food and preventing it from burning.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.
[0018] Reference Figure 1-4 As shown, the temperature-controlled lifting barbecue device includes a support 1, a grill 2, a tray 3, a temperature sensor 4, and a lifting assembly 5. The grill 2 is installed on the top of the support 1, the temperature sensor 4 is fixedly connected to the inside of the grill 2, and the tray 3 is located below the grill 2. The tray 3 and the grill 2 are connected by the lifting assembly 5. The lifting assembly 5 includes a driver 51, which is fixedly connected to the grill 2. The driver 51 is used to receive the signal from the temperature sensor 4 to drive the tray 3 to lift.
[0019] The main function of the support 1 is to stabilize the grill 2 and suspend the tray 3 in the air, allowing for some space between the tray 3 and the ground, which facilitates the adjustment of the position of the tray 3. Therefore, the support 1 can be fitted onto the grill 2 or the support 1 and the grill 2 can be integrally formed. Since the food is in direct contact with the grill 2, the control of the heat is concentrated at the grill 2. Therefore, the temperature sensor 4 detects when the temperature at the grill 2 is too high or too low. The driver 51 receives the signal from the temperature sensor 4 and controls the lifting component 5 after processing. Since the tray 3 and the grill 2 are connected by the lifting component 5, the distance between the tray 3 and the grill 2 can be controlled by the lifting component 5, thereby indirectly controlling the temperature at the grill 2.
[0020] This utility model is designed based on a charcoal grill. While maintaining the portability of a charcoal grill, in common charcoal grills, food is placed on the grill rack 2 and the heat is controlled by adding or removing fuel on the tray 3. However, the fuel is usually solid alcohol or charcoal, which means that the fuel cannot be removed when the heat needs to be reduced, making it difficult to control the heat. In order to solve this problem, existing technologies usually design a closed fuel chamber and multiple air regulating holes on the fuel chamber. When the air regulating holes are open, they can increase the air circulation and provide more oxygen for combustion, which will make the fire stronger. When the air regulating holes are reduced, the flame will weaken due to insufficient oxygen. However, in actual use, it has been found that when the lid is closed for simmering, the air regulating holes should not be completely closed. A gap should be left to prevent the charcoal from going out due to lack of oxygen. Therefore, users need to pay more attention to the fuel. This means that users need to pay attention to both the fuel and the food at the same time, which can easily lead to problems such as food burning. In addition, the setting of the fuel chamber adds extra components to the grilling device, which reduces portability.
[0021] To solve this problem, the temperature sensor 4 is placed inside the grill 2 to reduce the error between the detected temperature and the actual temperature of the food. Multiple temperature sensors 4 can be set to further reduce the error and monitor the temperature in real time so that the lifting component 5 can quickly control the distance between the tray 3 and the grill 2. This eliminates the need for manual adjustment by the user and avoids problems caused by the gas vent. The user only needs to focus on the food, and the fuel burns directly in contact with the food, so there is no need for additional parts to set up the fuel chamber, which can improve the portability of the entire grilling device.
[0022] This invention uses a temperature sensor 4 to detect the actual temperature near the grill 2, and a driver 51 to process the signal from the temperature sensor 4 and control the operation of the entire lifting assembly 5. This controls the grill 2 to move closer to or further away from the tray 3, thereby automatically adjusting the position of the tray 3 according to the temperature at the grill 2, thus controlling the temperature of the food and preventing it from burning.
[0023] Furthermore, the lifting assembly 5 also includes a threaded shaft 52, a first lifting arm 53, a threaded sleeve 54, and a first positioning member 55. The driver 51 is connected to the threaded shaft 52 and is used to drive the threaded shaft 52 to rotate. The threaded shaft 52 is threadedly connected to the threaded sleeve 54. The threaded sleeve 54 and the first positioning member 55 are both rotatably connected to the first lifting arm 53. The threaded sleeve 54 and the first positioning member 55 are respectively located at both ends of the first lifting arm 53. The end of the first positioning member 55 away from the first lifting arm 53 is fixedly connected to the tray 3.
[0024] The lifting assembly 5 also includes a second lifting arm 56, a slider 57, a track 58, and a second positioning member 59. The first lifting arm 53 and the second lifting arm 56 cross in an "X" shape and are hinged at the center. The slider 57 and the second positioning member 59 are both rotatably connected to the second lifting arm 56. The slider 57 and the second positioning member 59 are respectively located at both ends of the second lifting arm 56. The slider 57 is located in the track 58. The track 58 is fixedly connected to the tray 3. The end of the second positioning member 59 away from the second lifting arm 56 is fixedly connected to the grill 2.
[0025] The driver 51 processes the received signal from the temperature sensor 4, and then controls the threaded shaft 52 to rotate forward or backward. The rotating threaded shaft 52 drives the threaded sleeve 54 to move. The movement of the threaded sleeve 54 will drive the first lifting arm 53 to rotate. When the first lifting arm 53 rotates, its length in the vertical direction will change. The first positioning member 55 is fixedly connected to the tray 3, thereby enabling the tray 3 to move relative to the grill 2. The second lifting arm 56 rotates through its connection with the first lifting arm 53 and the cooperation of the track 58 and the slider 57, which plays a stable supporting role. In this way, the combination of the first lifting arm 53 and the second lifting arm 56 can realize the lifting and lowering of the tray 3 through the driver 51.
[0026] Furthermore, the grill 2 is also connected to multiple movable stabilization components 6 connected to the tray 3. The movable stabilization components 6 are used to maintain the stability of the tray 3 when it moves.
[0027] Furthermore, the mobile stabilization component 6 includes a third lifting arm 61, a first moving block 62, a first guide rail 63, and a third positioning component 64. The first moving block 62 and the third positioning component 64 are rotatably connected to the third lifting arm 61, and the first moving block 62 and the third positioning component 64 are respectively located at both ends of the third lifting arm 61. The first moving block 62 is located inside the first guide rail 63, and the first guide rail 63 is fixedly connected to the tray 3. The end of the third positioning component 64 away from the third lifting arm 61 is fixedly connected to the grill 2.
[0028] The mobile stabilization component 6 also includes a fourth lifting arm 65, a second moving block 66, a second guide rail 67, and a fourth positioning component 68. The second moving block 66 and the fourth positioning component 68 are rotatably connected to the fourth lifting arm 65, and the second moving block 66 and the fourth positioning component 68 are respectively located at both ends of the fourth lifting arm 65. The second moving block 66 is located inside the second guide rail 67, and the second guide rail 67 is fixedly connected to the grill 2. The end of the fourth positioning component 68 away from the fourth lifting arm 65 is fixedly connected to the tray 3.
[0029] The moving principle of the mobile stabilization component 6 is similar to that of the lifting component 5. The difference is that the mobile stabilization component 6 is a passive lifting component, and its main function is to maintain the stability of the pallet 3 when it is lifted.
[0030] Furthermore, the number of mobile stabilization components 6 is set to multiple.
