背景技术Background technique
中国专利号2016111955890公开的《一种双旋转烧烤装置》的技术方案，提供了一种不需要改变已有传动装置和烤架底盘的结构、不增加能耗和成本的双旋转烧烤装置，其技术构思是：允许上盖转动，利用上盖的惯性，通过对电控装置的设置，使驱动电机及烤架、驱动齿轮适时改变转向，保持上盖与驱动齿轮的相对转动，实现双旋转烧烤，该方案存在一个缺陷，驱动电机换向转动瞬间电流也非常大，如果没有过流保护措施，足以烧掉电机的线圈。这是用于由于烤架具有很大的转动惯量，其所搭载食物具有巨大的转动惯量，反向瞬间成为巨大的负载；另外，该方案只适合于双向电机，从适用性和经济性上说，都还有存在不足。中国专利号2016112150244公开的《一种双旋转烧烤装置》的技术方案，虽然能够解决上述这些不足，但是，由于驱动电机采用间歇运行模式，驱动电机处在暂停运行期间，烤架不转动，仅有食物绕自身轴线旋转，所以，严格意义上说，不是真正的双旋转烧烤模式，存在降低食物受热均匀性的不足。The technical solution of "a double-rotating barbecue device" disclosed in Chinese Patent No. 2016111955890 provides a double-rotating barbecue device without changing the structure of the existing transmission device and the grill chassis without increasing energy consumption and cost, and the technology thereof The idea is: allow the upper cover to rotate, use the inertia of the upper cover, and make the driving motor, the grill and the driving gear change the steering timely, and maintain the relative rotation of the upper cover and the driving gear through the setting of the electric control device, thereby realizing the double-rotation barbecue. There is a defect in this scheme. The current in the commutation of the drive motor is also very large. If there is no overcurrent protection measure, it is enough to burn the coil of the motor. This is because the grill has a large moment of inertia, the food it carries has a large moment of inertia, and the reverse moment becomes a huge load; in addition, the solution is only suitable for two-way motors, from the perspective of applicability and economy. There are still some shortcomings. The technical solution of "a double-rotating barbecue device" disclosed in Chinese Patent No. 2016112150244 can solve the above-mentioned deficiencies, but since the driving motor adopts the intermittent operation mode, the driving motor is in the pause operation, the grill does not rotate, only The food rotates around its own axis, so, strictly speaking, it is not a true double-rotation grilling mode, and there is a deficiency in reducing the uniformity of food heat.

具体实施方式detailed description
下面结合附图和实施例对本发明作进一步描述。The invention is further described below in conjunction with the drawings and embodiments.
实施例1Example 1
参见图1，本实施例包括环形烹饪腔1、双旋转烤架2、驱动电机3、电控装置4，所述的烤架2包括底盘2.1、立柱2.2、上梁2.3、组合载具2.4，其中组合载具包括环形上盖2.41、驱动齿轮2.42和下盖2.43，所述的环形上盖2.41的内壁2.412外侧设有与上述的驱动齿轮2.42咬合的咬齿，用于在驱动齿轮2.42随烤架2旋转时，使其产生绕自身轴线的旋转运动，所述的上盖2.41与在环形上盖2.41的内壁2.412的内侧设有配重梁2.413，在该梁的中心处设有下垂的配重2.414，用于增加上盖的转动惯量，烧烤时，通过电控装置4控制驱动电机3运行速度，使烤架2摆脱所搭载的组合载具2.4的上盖2.41的跟随，使上盖2.41与上述的驱动齿轮2.42相对旋转运动，形成驱动齿轮2.42在绕烤架2的轴线旋转的同时，绕自身轴线旋转。具体说，所述的驱动电机3采用双速交替运行模式，与电机3双速对应的烤架2的转速分别为V1＝4r/min和V2＝10r/min，启动时，烤架2以转速V1＝4r/min旋转运动，经过设定时间t1后，转换到以转速V2＝10r/min旋转运动，经过设定时间t2后，转回到以转速V1＝4r/min旋转运动，在经过设定时间t1后，再转换到以转速V2＝10r/min旋转运动，……循环往复，交替运行，所述的设定时间t1、t2是依据设定的算法，结合具体设备参数和试验结果得到的，具体说，时间t1从烤架2转速转换到转速V1＝4r/min时起，到上盖2.41转速Vg满足|V1-Vg|≤Vc*r/R时止，所用的时间的试验平均值，时间t2从烤架2转速转换到转速V2＝10r/min时起，到上盖2.41转速Vg满足|V2-Vg|≤Vc*r/R时止，所用的时间的试验平均值。上述的Vc是设定的驱动齿轮2.42的最低自转速度，本实施例中Vc＝10r/min，|V1-Vg|和|V2-Vg|是烤架2与上盖2.41转速差的绝对值，r/R是驱动齿 轮2.42外径与上盖内壁2.412外径的比值，本实施例中取值1/10，通过简单数学变换和计算可知，上述的t1就是从烤架2变速到V1＝4r/min时起，到上盖2.41与烤架2转速差进入1r/min内时止，所用的平均时间，上述的t2就是从烤架2变速到V2＝10r/min时起，到上盖2.41与烤架2转速差进入1r/min内时止，所用的平均时间，采用本实施例提供的上述方法确定驱动电机3交替转换周期的双旋转烧烤装置，不仅可以避免在所述的上盖2.41的转速接近烤架2的转速的时间段里，驱动齿轮2.42自转过于缓慢削弱双旋转烧烤效果的情况发生，而且，可以准确的设定驱动齿轮2.42的最低转速，确保双旋转烧烤的效果，从而量化地把握、提升食物的受热均匀性。Referring to Fig. 1, the embodiment includes an annular cooking chamber 1, a double rotating grill 2, a driving motor 3, and an electric control device 4. The grill 2 includes a chassis 2.1, a column 2.2, an upper beam 2.3, and a combined carrier 2.4. The combination carrier includes an annular upper cover 2.41, a driving gear 2.42 and a lower cover 2.43. The outer side of the inner wall 2.412 of the annular upper cover 2.41 is provided with a bite that engages with the driving gear 2.42 described above for baking on the driving gear 2.42. When the frame 2 rotates, it generates a rotary motion about its own axis. The upper cover 2.41 and the inner wall 2.412 of the annular upper cover 2.41 are provided with a weight beam 2.413, and a sagging fit is provided at the center of the beam. The weight is 2.414, which is used to increase the moment of inertia of the upper cover. When grilling, the operating speed of the driving motor 3 is controlled by the electronic control device 4, so that the grill 2 is freed from the following cover 2.41 of the assembled carrier 2.4, so that the upper cover 2.41 The rotational movement relative to the drive gear 2.42 described above causes the drive gear 2.42 to rotate about its own axis while rotating about the axis of the grill 2. Specifically, the driving motor 3 adopts a two-speed alternate operation mode, and the rotation speed of the grill 2 corresponding to the double speed of the motor 3 is V1=4r/min and V2=10r/min, respectively, and the grill 2 rotates at the time of starting. V1=4r/min rotary motion. After the set time t1, it will switch to the rotary motion with the speed V2=10r/min. After the set time t2, it will return to the rotary motion with the speed V1=4r/min. After the fixed time t1, it is switched to the rotational motion with the rotational speed V2=10r/min, ... cyclically and alternately, the set times t1 and t2 are obtained according to the set algorithm, combined with the specific equipment parameters and test results. Specifically, the time t1 starts from the rotation speed of the grill 2 to the speed V1=4r/min, and the test average of the time used when the upper cover 2.41 rotational speed Vg satisfies |V1-Vg|≤Vc*r/R The value, time t2 is the average value of the test used for the time used when the upper cover 2.41 rotational speed Vg satisfies |V2-Vg| ≤ Vc*r/R from the rotation of the grill 2 to the rotational speed V2=10r/min. The above Vc is the minimum rotation speed of the set drive gear 2.42. In the present embodiment, Vc=10r/min, |V1-Vg| and |V2-Vg| are the absolute values of the difference between the rotation speed of the grill 2 and the upper cover 2.41. r/R is the drive tooth The ratio of the outer diameter of the wheel 2.42 to the outer diameter of the inner wall of the upper cover 2.412 is 1/10 in this embodiment. It can be seen from the simple mathematical transformation and calculation that the above t1 is from the shift of the grill 2 to V1=4r/min. When the difference between the upper cover 2.41 and the grill 2 is 1 r/min, the average time used is t2 from the grill 2 to V2=10r/min, to the upper cover 2.41 and the grill 2 When the difference is within 1 r/min, the average time used, the above-mentioned method provided in this embodiment is used to determine the double-rotation grilling device of the alternating conversion cycle of the driving motor 3, and the speed of the upper cover 2.41 can be prevented from approaching the grill. During the period of 2 rpm, the drive gear 2.42 rotates too slowly to weaken the double-rotation grilling effect. Moreover, the minimum speed of the drive gear 2.42 can be accurately set to ensure the effect of the double-rotation grilling, thereby quantitatively grasping and improving. The heat uniformity of the food.
实施例2Example 2
本实施例与实施例1的区别主要在于：驱动电机3的速度交替转换周期及其确定方法，由于：烤架2的转速由V2＝10r/min转到V1＝4r/min后，上盖2.41与下盖2.43间的摩擦阻力起到加快上盖2.41转速接近烤架2的转速的作用，烤架2的转速由V1＝4r/min转到V2＝10r/min后，上盖2.41与下盖2.43间的摩擦阻力起到延缓上盖2.41转速接近烤架2的转速的作用，因此，t1＜t2，把驱动电机3的速度交替转换周期设为2t1的影响仅在于使所述的驱动齿轮2.42的最低转速在驱动电机3由高速转到低速前略高于10r/min，并无坏处，好处是每次变速间隔时间都相同，都是t1，即具有相同的延时，这使得电控装置4可以简化控制程序或控制电路，节省成本。其余，未涉及之处于实施例1或实施例2相同。The difference between this embodiment and the embodiment 1 mainly lies in: the speed alternating conversion period of the driving motor 3 and the determining method thereof, since the rotating speed of the grill 2 is changed from V2=10r/min to V1=4r/min, the upper cover 2.41 The frictional resistance between the lower cover and the lower cover 2.43 functions to accelerate the rotation speed of the upper cover 2.41 to the rotation speed of the grill 2. The rotation speed of the grill 2 is changed from V1=4r/min to V2=10r/min, and the upper cover 2.41 and the lower cover The frictional resistance between 2.43 acts to delay the rotation speed of the upper cover 2.41 to approach the rotation speed of the grill 2. Therefore, t1 < t2, the effect of setting the speed alternate switching period of the drive motor 3 to 2t1 is only to make the drive gear 2.42. The minimum speed is slightly higher than 10r/min before the drive motor 3 is turned from high speed to low speed. There is no disadvantage. The advantage is that each shift interval is the same, both are t1, that is, have the same delay, which makes the electronic control device 4 It can simplify control programs or control circuits and save costs. The rest, which is not involved, is the same as in Embodiment 1 or Embodiment 2.
