在本方案中，在满足1.05≤E/D≤2.4的前提下，控制E＝2G+F+D，即 扣槽部在扣牙底端与扣槽部内底面的任一抵靠点的纵向上的纵向高度E， 等于扣牙纵向高度D、扣槽部的壁厚G的两倍及扣牙顶面与扣槽部之间间 隙在前述的该任一抵靠点的纵向上的纵向宽度F这三者之和，这样，E、G、 F、D这四个参数之间的变化相互牵制，且满足：1.05≤E/D≤2.4及E＝2G+F+D，这不仅可使得参数改良后的扣槽部与扣牙的扣合强度总是朝着增 强趋势发展，以实现基于提升扣槽部与扣牙扣合强度目的改良的针对性和有效 性，且可使得增加扣牙、扣槽部壁厚所带来的扣合强度提升效果成倍实现， 并避免了现有技术中由于单一增加扣牙、扣槽部壁厚所导致的控制扣槽部 与扣牙扣合或分离的操作手感降低等不良影响，同时也避免了单一调整扣 槽部或扣牙参数时，由于众多参数之间的变化协调性不足而导致的扣合强 度不升反降的问题。In this scheme, under the premise of satisfying 1.05≤E/D≤2.4, control E=2G+F+D, that is, the buckle groove is in the longitudinal direction of any contact point between the bottom end of the buckle tooth and the inner bottom surface of the buckle groove The longitudinal height E is equal to the longitudinal height D of the button tooth, twice the wall thickness G of the button groove part and the longitudinal width F of the gap between the top surface of the button tooth and the button groove part in the longitudinal direction of any of the aforesaid abutment points The sum of these three, in this way, the changes between the four parameters of E, G, F, and D are mutually restrained, and satisfy: 1.05≤E/D≤2.4 and E=2G+F+D, which not only makes the parameters The buckling strength of the improved buckle groove and buckle teeth always tends to increase, so as to achieve the pertinence and effectiveness of the improvement based on the purpose of improving the buckle groove and buckle teeth buckle strength, and can increase the buckle teeth, The fastening strength improvement effect brought about by the wall thickness of the buckle groove is doubled, and it avoids the control of the fastening or separation of the buckle groove and the buckle teeth caused by the single increase of the buckle teeth and the wall thickness of the buckle groove in the prior art At the same time, it also avoids the problem that the buckle strength does not increase but decreases due to insufficient coordination of changes among many parameters when adjusting the buckle groove or buckle tooth parameters alone.
上述技术方案中，所述F≥0.3mm。In the above technical solution, said F≥0.3mm.
在本方案中，基于F≥0.3mm去协调1.05≤E/D≤2.4及E＝2G+F+D中 的E、G及D这三者的关系，这样可以确保扣牙在扣槽部内具有足够的活 动量，以确保控制扣槽部与扣牙扣合或分离时具有较佳的操作手感，避免 了现有技术中由于单一增加扣牙、扣槽部壁厚所导致的控制扣槽部与扣牙 扣合或分离的操作手感降低等不良影响，同时，可使得参数改良后的扣槽部 与扣牙的扣合强度总是朝着增强趋势发展，以实现基于提升扣槽部与扣牙扣合强度目的改良的针对性和有效性。In this scheme, based on F≥0.3mm to coordinate the relationship between E, G and D in 1.05≤E/D≤2.4 and E=2G+F+D, it can ensure that the buckle teeth have Sufficient amount of activity to ensure a better operating feel when the control buckle groove is engaged or separated from the buckle teeth, and avoids the control buckle groove caused by a single increase in the wall thickness of the buckle teeth and the buckle groove in the prior art At the same time, the fastening strength between the buckle groove and the buckle teeth after the parameter improvement can always develop towards an enhanced trend, so as to realize the improvement based on the improvement of the buckle groove and buckle The pertinence and effectiveness of occlusal strength purpose improvement.

在本方案中，基于扣槽部的壁厚G为0.2mm～3mm去协调1.05≤E/D ≤2.4及E＝2G+F+D中的E、F及D这三者的关系，其中，通过控制扣槽部 壁厚大于等于0.2mm以确保扣槽部满足自身的强度需求，且通过控制扣槽 部壁厚小于等于3mm，以相应牵制D、G、F的取值，尤其牵制D和F的 取值，若G超过3mm，不仅会带来加工不方便、成本高等问题，且D和F 的取值会随之增加以满足1.05≤E/D≤2.4的关系，D若过大会增加成本且 扣牙加工质量难以保证，而F若过大会降低扣牙和扣槽部的扣合紧密性， 容易出现异响和松动问题，而通过控制G为0.2mm～3mm，在满足提升承 压强度效果的同时，可以兼顾实现D满足扣牙自身的强度需求又不会造成 成本激增问题，同时实现F满足控制扣槽部与扣牙扣合或分离时具有较佳 的操作手感，又不会导致扣合后异响和松动问题。In this solution, the relationship between E, F and D in 1.05≤E/D≤2.4 and E=2G+F+D is coordinated based on the wall thickness G of the buckle groove part being 0.2mm~3mm, wherein, By controlling the wall thickness of the buckle groove to be greater than or equal to 0.2mm to ensure that the buckle groove meets its own strength requirements, and by controlling the wall thickness of the buckle groove to be less than or equal to 3mm, the values of D, G, and F are controlled accordingly, especially D and For the value of F, if G exceeds 3mm, it will not only bring problems such as inconvenient processing and high cost, but also the values of D and F will increase accordingly to meet the relationship of 1.05≤E/D≤2.4. If D is too large, it will increase Cost and the processing quality of the buckle teeth are difficult to guarantee, and if F is too large, the fastening tightness of the buckle teeth and the buckle groove will be reduced, and abnormal noise and looseness will easily occur. At the same time as the strength effect, it is possible to realize D to meet the strength requirements of the buckle itself without causing a sharp increase in cost. At the same time, to achieve F to satisfy the need to control the buckle groove and the buckle to buckle or separate. Causes abnormal noise and looseness after buckling.

This design is based on the longitudinal height of the buckle D≤10mm (such as 0mm<D≤10mm) To coordinate the relationship between E, F and G in 1.05≤E/D≤2.4 and E=2G+F+D, so as to control the values of E, G and F, especially the values of G and F , if D exceeds 10mm, it is necessary to design G and F with larger values to meet the relationship of 1.05≤E/D≤2.4, resulting in extremely high product costs and the effect of increasing the buckle strength is not obvious, and the buckle teeth The processing quality is difficult to guarantee, and the fastening tightness of the buckle teeth and the buckle groove is poor. By controlling D≤10mm, while satisfying the effect of improving the bearing strength, it is possible to realize the buckle groove to meet its own strength requirements without The problem of cost surge is caused, and at the same time, F satisfies the need to control the fastening or separation of the buckle groove and the buckle tooth with a better operating feel, without causing abnormal noise and looseness after buckling.

可选地，烹饪设备为压力锅、电压力锅或微压饭煲。Optionally, the cooking equipment is a pressure cooker, an electric pressure cooker or a micro-pressure rice cooker.
在本发明的一个具体地实施例中，如图1所示，烹饪设备为电压力锅，包 括：内锅20、锁扣10、密封圈30、发热部件及锅盖40，发热部件用于向内锅20供热，当发热部件加热，内锅20内由于受热产生蒸汽，锅盖40通过密封 圈30与内锅20作用产生密封，蒸汽由于密封圈30的密封作用在内锅20内产 生压力，内锅20中起压时，通过内锅20的扣牙21与锁扣10的扣槽部11相 互扣合来进行承压，随着内锅20中压力的升高，对承压强度的要求也越来越高，影响承压强度的主要因素如下：In a specific embodiment of the present invention, as shown in FIG. 1 , the cooking equipment is an electric pressure cooker, including: an inner pot 20, a lock 10, a sealing ring 30, a heating element and a pot cover 40, and the heating element is used to inwardly The pot 20 supplies heat. When the heat-generating parts are heated, the inner pot 20 generates steam due to the heat, and the pot cover 40 forms a seal with the inner pot 20 through the sealing ring 30 , and the steam generates pressure in the inner pot 20 due to the sealing effect of the sealing ring 30 . When the inner pot 20 is under pressure, the buckle teeth 21 of the inner pot 20 and the buckle groove 11 of the lock buckle 10 are interlocked to bear the pressure. As the pressure in the inner pot 20 rises, the requirements for the bearing strength The main factors affecting the bearing strength are as follows:
A-内锅20壁厚为A，基本取决于内锅20材料的壁厚，内锅20材料的壁 厚越大，即A越大，承压强度越高；A-the wall thickness of the inner pot 20 is A, which basically depends on the wall thickness of the material of the inner pot 20, the larger the wall thickness of the inner pot 20 material, that is, the larger A, the higher the bearing strength;
B-内锅20与锁扣10配合后，内锅20的扣牙21外沿与锁扣10的扣槽部 11之间间隙的横向宽度为B，本实施例中优选B在0.3mm及以上，防止间隙 过小导致内锅20与锁扣10在旋合时出现不顺畅的问题；B- After the inner pot 20 is matched with the lock buckle 10, the lateral width of the gap between the outer edge of the buckle teeth 21 of the inner pot 20 and the buckle groove 11 of the lock buckle 10 is B.

C-内锅20侧壁与内锅20扣牙21的下支撑臂212之间的横向间距为C， 其中，C越大，受力点越向靠外，力臂越长，承压越差；C-The lateral distance between the side wall of the inner pot 20 and the lower support arm 212 of the inner pot 20 buckle 21 is C, wherein, the larger C is, the more outward the point of force is, the longer the moment arm is, the worse the pressure will be ;
D-内锅20的扣牙21的纵向高度为D，本实施例中优选D在0～10mm，满 足该条件下扣牙21越高，即D越大，承压强度越好；D-The vertical height of the buckle 21 of the inner pot 20 is D, and in this embodiment, the preferred D is 0-10mm. Under this condition, the higher the buckle 21 is, that is, the larger D is, the better the bearing strength is;
E-锁扣10的扣槽部11的纵向高度为E；The longitudinal height of the buckle groove part 11 of the E-lock buckle 10 is E;
F-内锅20的扣牙21与锁扣10的扣槽部11内顶面之间间隙的纵向高度为 F，本实施例中优选F在0.3mm及以上，防止间隙过小导致内锅20与锁扣10 在旋合时出现不顺畅的问题；F- The longitudinal height of the gap between the buckle teeth 21 of the inner pot 20 and the inner top surface of the buckle groove part 11 of the lock buckle 10 is F. In this embodiment, F is preferably 0.3 mm or more to prevent the inner pot 20 from being too small. There is an unsmooth problem when screwing with the lock 10;
G-锁扣10的扣槽部11的壁厚为G，基本取决于锁扣10材料的壁厚，锁 扣10材料的壁厚越大，即G越大，承压强度越高；The wall thickness of the buckle groove portion 11 of the G-lock 10 is G, which basically depends on the wall thickness of the material of the lock 10. The greater the wall thickness of the material of the lock 10, that is, the greater the G, the higher the bearing strength;
在本实施例中，如图2所示，E＝2G+F+D，现定义E/D＝H，则相应地， H＝(2G+F+D)/D＝(2G/D)+(F/D)+1，其中，H需要满足大于等于1.05且小于 等于2.4，其中，按照相关国标以及认证的需求，锅体的承压强度必须满足相 应的要求，本方案进一步限定G为0.2mm～3mm，且进一步限定F大于等于 0.3mm，且进一步限定D小于等于10mm，本方案的产品，可充分发挥并综合 性地提升由于扣槽部11、扣牙21的材料壁厚增大所带来的承压强度效果，实 现满足不同要求的承压需求，同时兼顾提升产品控制扣槽部11与扣牙21扣合 或分离时的操作体验。In this embodiment, as shown in Figure 2, E=2G+F+D, now define E/D=H, then correspondingly, H=(2G+F+D)/D=(2G/D)+ (F/D)+1, where H needs to be greater than or equal to 1.05 and less than or equal to 2.4, wherein, according to the relevant national standards and certification requirements, the pressure-bearing strength of the pot body must meet the corresponding requirements, and this scheme further limits G to 0.2 mm to 3mm, and it is further defined that F is greater than or equal to 0.3mm, and further defined that D is less than or equal to 10mm. The product of this scheme can fully exert and comprehensively improve the material thickness of the buckle groove 11 and the buckle tooth 21. The pressure-bearing strength effect brought about can meet the pressure-bearing requirements of different requirements, and at the same time improve the operation experience when the product controls the buckle groove part 11 and the buckle tooth 21 to be buckled or separated.
综上所述，本发明提供的烹饪设备，除了常规地对扣牙壁厚、扣槽部壁厚、 扣槽部与扣牙配合间隙等参数分别设计外，通过综合地控制扣牙的纵向高度 D和扣槽部的纵向高度E满足1.05≤E/D≤2.4，相对于仅单一地增加扣牙 壁厚、增加扣槽部壁厚及合理调整扣槽部与扣牙配合间隙等改良手段而言， 可使得扣牙壁厚、扣槽部壁厚及扣槽部与扣牙配合间隙等参数在改良变化时 更具协调性，这不仅可使得参数改良后的扣槽部与扣牙的扣合强度总是朝着增 强趋势发展，以实现基于提升扣槽部与扣牙扣合强度目的改良的针对性和有效 性，且可使得增加扣牙、扣槽部壁厚所带来的扣合强度提升效果成倍实现， 并避免了现有技术中由于单一增加扣牙、扣槽部壁厚所导致的控制扣槽部 与扣牙扣合或分离的操作手感降低等不良影响，同时也避免了单一调整扣 槽部或扣牙参数时，由于众多参数之间的变化协调性不足而导致的扣合强 度不升反降的问题。In summary, the cooking equipment provided by the present invention, in addition to conventionally designing parameters such as the thickness of the buckle tooth, the wall thickness of the buckle groove, and the gap between the buckle groove and the buckle tooth, etc., by comprehensively controlling the longitudinal height of the buckle teeth D and the longitudinal height E of the buckle groove satisfy 1.05≤E/D≤2.4, compared with the improvement methods such as simply increasing the wall thickness of the buckle teeth, increasing the wall thickness of the buckle groove, and reasonably adjusting the matching gap between the buckle groove and the buckle teeth. In other words, it can make the parameters such as the wall thickness of the buckle tooth, the wall thickness of the buckle groove, and the matching gap between the buckle groove and the buckle tooth more coordinated when improving and changing. The joint strength always tends to increase, in order to achieve the pertinence and effectiveness of improvement based on the purpose of improving the fastening strength of the buckle groove and the buckle teeth, and can make the fastening brought about by increasing the wall thickness of the buckle teeth and the buckle groove. The strength improvement effect is doubled, and avoids the adverse effects of the prior art, such as the decrease in the operating feel of controlling the engagement or separation of the buckle groove and the buckle teeth due to the single increase of the buckle teeth and the wall thickness of the buckle groove. Solve the problem that the fastening strength does not increase but decreases due to insufficient coordination of changes among many parameters when adjusting the buckle groove or buckle tooth parameters alone.
