具体实施方式
为了能够更清楚地理解本发明的上述目的、特征和优点,下面结合附图和具体实施方式对本发明进行进一步的详细描述。需要说明的是,在不冲突的情况下,本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本发明,但是,本发明还可以采用其他不同于在此描述的其他方式来实施,因此,本发明的保护范围并不受下面公开的具体实施例的限制。
下面参照图1至图96描述根据本发明一些实施例所述的外壳组件及烹饪器具。
如图1至图89所示,本发明第一方面的实施例提供的外壳组件,用于电磁感应加热的烹饪器具,外壳组件套设在烹饪器具的内胆的外侧,外壳组件包括:金属外壳10和绝缘件20。
具体地,金属外壳10整体呈断开的环状,且金属外壳10的断开处形成缺口11;绝缘件20连接金属外壳10的断开端,并覆盖缺口11,使外壳组件形成闭环的断路结构。
本发明第一方面的实施例提供的外壳组件,通过把金属外壳10断开,用 绝缘件20将其断开处连接起来,使得外壳组件在电路上是断开的,从而可以减弱金属外壳10对磁场的感应,以降低温升,解决了现有技术中金属外壳10形成闭环回路导致容易感应线圈盘产生的磁场而发热致使温升过高的问题;且绝缘件20连接金属外壳10的断开处,并覆盖缺口11,使外壳组件形成闭环结构,从而保证了外壳组件的完整性,进而保证了烹饪器具的外观。
可以理解的是,一个缺口11对应金属外壳10的两个断开端,故而一个缺口11处的绝缘件20应该与该缺口11处的金属外壳10的两个断开端相连,以保证外壳组件形成完整的环状结构。至于一个缺口11处的绝缘件20的数量,可以是一个,也可以是两个(比如金属外壳10的内外两侧各安装一个绝缘件20)或更多个,不受具体限制。
进一步地,缺口11沿金属外壳10的周向方向上的宽度a大于或等于2mm,如图1、图3、图4和图10所示。
优选地,金属外壳10的尾部顶端设有安装槽17,缺口11的数量为一个,且缺口11位于安装槽17的下方,并与安装槽17相连通,如图1、图3、图4、图7、图10、图12和图14所示。
优选地,缺口11呈方形,如图1、图3和图10所示。
在上述实施例中,使缺口11沿金属外壳10的周向方向上的宽度大于或等于2mm,是为了保证金属外壳10的断开处具有一定的间距,以避免间距过小导致断开处产生火花、发热等情况,从而保证了产品的安全性和使用可靠性。
由于一个缺口11即可保证外壳组件不会形成电路上的闭环回路,因此只设置一个缺口11即可实现本发明的目的;且一个缺口11能够将绝缘件20的数量降至最低,从而既节约了成本,又提高了生产效率。而将缺口11开设在金属外壳10的尾部,一方面使得缺口11和绝缘件20位于烹饪器具不常见的位置处,从而提高了烹饪器具整体的美观度;另一方面,金属外壳10的尾部一般设有用于安装铰链或与烹饪器具的其他结构相适配的安装槽17,将缺口11设在此处,能够相对减小缺口11的尺寸,从而进一步提高了产品的美观度。
至于缺口11的具体高度b(沿金属外壳10轴线方向)和具体宽度a(沿金属外壳10周向方向,优选大于或等于2mm),可以根据产品的结构进行调整。
当然,缺口11的数量也可以为多个,多个缺口11处均用绝缘件20连接起来,同样也能够实现本发明的目的,因此也在本发明的保护范围内;缺口11的数量为一个时,也可以开设在金属外壳10的其他部位,本领域的技术人员应当理解,这些实施例均应在本发明的保护范围内。
缺口11呈方形(长方形或正方形),既便于加工成型,又便于与绝缘件20的装配,且形状规则,较为美观。当然,缺口11的形状不限于上述方形,也可以是其他形状,在此不再一一列举,但都应在本发明的保护范围内。
下面结合一些具体实施例,来详述绝缘件20与金属外壳10的装配结构。
实施例一(如图1至图9所示)
金属外壳10和绝缘件20中的一个上设有卡扣21,另一个上设有卡孔14,卡扣21与卡孔14相配合,使金属外壳10与绝缘件20相卡接,如图1、图4、图5和图7所示。
在该实施例中,通过卡扣21和卡孔14的配合,使金属外壳10与绝缘件20卡接在一起,既保证了金属外壳10与绝缘件20之间的固定连接,且使得装配过程更加简单快捷,有利于提高装配效率。
具体地,如前所述,一个绝缘件20与金属外壳10的两个断开端相连,故而卡扣21和卡孔14优选都是两组,分别位于缺口11的两侧,以保证绝缘件20与金属外壳10之间的可靠连接,如图1、图4和图5所示。优选地,每组卡扣21中,至少一个卡扣21的尾部设有倒刺211,金属外壳10或绝缘件20上相应设有凸包16,卡扣21穿过卡孔后,倒刺211钩在凸包16上,以防止卡扣21脱出卡孔,如图9所示。
优选地,卡扣21设在绝缘件20上,卡孔14设在金属外壳10上,如图1至图9所示,这样,卡扣21和卡孔14的具体配合结构可以隐藏在外壳组件的内部,而不会暴露在外,使得外壳组件的外观更加平整,从而进一步提高了烹饪器具的美观度;另一方面,相较于在绝缘件20上设置卡孔14的方案而言,在绝缘件20上设置卡合件,有利于提高绝缘件20的强度,以提高绝缘件20的使用寿命。
当然,本领域的技术人员应当理解,金属外壳10与绝缘件20也可以通过其他方式固定在一起,比如通过紧固件(螺钉、铆钉等)、粘接等方式,在此 不再一一列举,由于均能够实现本发明的目的,且没有脱离本发明的设计思想和宗旨,因而均应在本发明的保护范围内。
进一步地,绝缘件20上设有与缺口11相适配的定位筋22,如图1、图4、图5和图7所示。
优选地,定位筋22的数量为多个,且多个定位筋22沿金属外壳10的轴线方向平行排布,如图1、图5和图7所示。
绝缘件20上设有与缺口11相适配的定位筋22,能够用于装配时防呆。具体地,在装配时,可以先将定位筋22插入缺口11内,这样能够确定绝缘件20与金属外壳10的相对位置关系,起到定位的作用,使金属外壳10和绝缘件20相互连接的部位(比如:卡扣21和卡孔14)能够迅速对准,从而也提高了外壳组件的装配效率。
由于缺口11贯穿了金属外壳10的轴线方向,因而具有一定的高度,故而设置多个定位筋22,使其沿金属外壳10的轴线方向平行排布,能够与缺口11的多个部位相适配,因而定位更为准确。具体地,多个定位筋22的高度可以相同,也可以不同,相邻的定位筋22之间的距离,可以相同,也可以不同。
实施例二(如图10至图15所示)
金属外壳10为镶件,绝缘件20为塑料件,绝缘件20与金属外壳10为注塑成型的一体式结构。
绝缘件20为塑料件,塑料件是良好的绝缘体,能够有效保证外壳组件在电路上是断开的,而不会形成闭环回路;且塑料件的成型工艺简单,易于通过注塑成型加工成各种所需的形状,因此对缺口11的形状的要求较低,便于根据产品的具体结构进行各种合理的设计。
具体地,将金属外壳10作为镶件放入模具中,然后向模具内注入液态塑料,液态塑料会填充金属外壳10的断开处,以覆盖缺口11,并粘附在金属外壳10上,使二者连接在一起,使用二次注塑工艺,即可在模具内成型出完整的外壳组件,而硬化后金属外壳10上的塑料部分即为绝缘件20。
进一步地,金属外壳10上设有通孔12,如图10、图11和图15所示,绝缘件20的局部嵌入通孔12中。
进一步地,金属外壳10上设有限位凸起13,如图10、图11和图15所示, 限位凸起13嵌入绝缘件20中。
金属外壳10上设有通孔12,则在成型的过程中,液态塑料也会填充金属外壳10上的通孔12,待液态塑料硬化后,其形成的绝缘件20便会有一部分结构嵌入金属外壳10中,使得绝缘件20和金属外壳10相互镶嵌,从而既提高了绝缘件20与金属外壳10之间的粘附力,进而提高了绝缘件20与金属外壳10之间的连接强度,又起到了一定的限位作用,保证了金属外壳10与绝缘件20之间的相对稳定,从而进一步提高了外壳组件的使用可靠性。
优选地,缺口11的两侧均设有至少一个通孔12,以保证绝缘件20与缺口11两侧的金属外壳10的断开端均能够可靠连接,如图10和图11所示;优选地,缺口11两侧的通孔12相互对称,这样金属外壳10的断开端受力较为均匀,如图10和图11所示;进一步地,对于缺口11两侧均设有多个通孔12的情况而言,同一侧的多个通孔12的大小可以相同,也可不同,不受具体限制,如图10和图11所示。
同理,金属外壳10上设有限位凸起13,则待液态塑料硬化后,限位凸起13也会嵌入绝缘件20中,即金属外壳10的一部分结构也嵌入绝缘件20中,使得绝缘件20和金属外壳10相互镶嵌,从而也提高了绝缘件20与金属外壳10之间的粘附力,进而进一步提高了绝缘件20与金属外壳10之间的连接强度,又起到了一定的限位作用,进一步保证了金属外壳10与绝缘件20之间的相对稳定,从而进一步提高了外壳组件的使用可靠性。
优选地,缺口11的两侧均设有至少一个限位凸起13,如图10和图11所示,以进一步保证绝缘件20与缺口11两侧的金属外壳10的断开端均能够可靠连接;优选地,缺口11两侧的限位凸起13相互对称,这样金属外壳10的断开端受力也较为均匀;优选地,限位凸起13临近通孔12。
在上述两个实施例中,金属外壳10位于缺口11的两侧的部分向内凹陷,形成与绝缘件20的尺寸相适配的下沉台阶15,如图1、图2、图10和图11所示,使绝缘件20的外表面与金属外壳10的外表面相平齐,如图图5、图8、图12和图15所示。
在金属外壳10上设置下沉台阶15,能够使绝缘件20的外表面与金属外壳10的外表面相平齐,从而提高了外壳组件的美观度,进而提升了烹饪器具 的档次。
如图16至图57所示,在本发明的一些实施例中,所述绝缘件的数量与所述缺口的数量相等,并一一对应。
在这些实施例中,通过把金属外壳10’断开,用绝缘件20’将其断开处连接起来,使得外壳组件在电路上是断开的,从而可以减弱金属外壳10’对磁场的感应,以降低温升,解决了现有技术中金属外壳10’形成闭环回路导致容易感应线圈盘产生的磁场而发热致使温升过高的问题;且绝缘件20’连接金属外壳10’的断开处,并覆盖缺口11’,使外壳组件形成闭环结构,则保证了外壳组件的完整性,进而保证了烹饪器具的外观;此外,绝缘件20’的数量与缺口11’的数量相等,并一一对应,即一个缺口11’处只安装一个绝缘件20’,这样既保证了外壳组件的完整性,又减少了绝缘件20’的数量,因而既能够节约成本,又能够提高装配效率。
可以理解的是,一个缺口11’对应金属外壳10’的两个断开端,故而一个缺口11’处的绝缘件20’应该与该缺口11’处的金属外壳10’的两个断开端相连,以保证外壳组件形成完整的环状结构。
下面结合一些具体实施例来详述绝缘件20’的数量与缺口的数量相等且一一对应时,绝缘件20’与金属外壳10’的装配结构。
实施例三(如图16至图24所示)
金属外壳10’和绝缘件20’中的一个上设有卡孔12’,另一个上设有卡合件,卡合件与卡孔12’相配合,使绝缘件20’与金属外壳10’相卡接。
其中,卡合件为L形卡扣30’,L形卡扣30’贯穿卡孔12’,并抵靠在金属外壳10’和绝缘件20’中的一个上。
通过卡合件和卡孔12’的配合,使金属外壳10’与绝缘件20’卡接在一起,既保证了金属外壳10’与绝缘件20’之间的固定连接,且使得装配过程更加简单快捷,有利于提高装配效率。具体地,如前,一个绝缘件20’与金属外壳10’的两个断开端相连,故而卡合件和卡孔12’优选都是两组,分别位于缺口11’的两侧,以保证绝缘件20’与金属外壳10’之间的可靠连接。
其中,卡合件为L形卡扣30’,即卡合件呈单边钩状,安装时,先将L形卡扣30’穿过卡孔12’,待绝缘件20’和金属外壳10’压合到位后,沿着L形卡 扣30’的弯折方向推动L形卡扣30’,直至卡扣的一端抵靠在卡孔12’的孔壁上,此时,卡扣的另一端即抵靠在金属外壳10’或绝缘件20’上,实现了金属外壳10’与绝缘件20’之间的卡接。
优选地,L形卡扣30’的数量为多个,并分为两组,两组L形卡扣30’分别位于缺口11’的两侧;其中,两组L形卡扣30’朝向相同的方向;或,L形卡扣30’位于绝缘件20’上,两组L形卡扣30’均朝向缺口11’;或,L形卡扣30’位于金属外壳10’上,两组L形卡扣30’均背离缺口11’。
L形卡扣30’的数量为多个,能够进一步确保金属外壳10’与绝缘件20’之间的可靠连接;两组L形卡扣30’朝向相同的方向(如:一致向上、一致向下、一致向左或一致向右等),便于所有的L形卡扣30’同步装配,以实现一步安装到位;当L形卡扣30’位于绝缘件20’上时,两组L形卡扣30’均朝向缺口11’,即两组L形卡扣30’的朝向相对,则装配到位时,由于金属外壳10’的两个断开端有向两侧分开的趋势,恰好与L形卡扣30’的脱出方向相反(两个断开端相互靠近时,L形卡扣30’才能脱出),故而L形卡扣30’不易脱出卡孔12’,连接更加可靠;同理,当L形卡扣30’位于金属外壳10’上时,两组L形卡扣30’均背离缺口11’,即两组L形卡扣30’的朝向相反,则装配到位时,由于金属外壳10’的两个断开端有向两侧分开的趋势,也恰好与L形卡扣30’的脱出方向相反(两个断开端相互靠近时,L形卡扣30’才能脱出),故而L形卡扣30’不易脱出卡孔12’,连接也更加可靠。
优选地,每组L形卡扣30’中,至少一个L形卡扣30’的尾部设有倒刺31’,金属外壳10’和绝缘件20’中的一个上设有凸包13’,倒刺31’钩在凸包13’上。
倒刺31’与凸包13’相配合,对L形卡扣30’起到了限位作用,能够避免L形卡扣30’反向滑动导致绝缘件20’脱落,从而进一步确保了金属外壳10’与绝缘件20’的可靠连接。
实施例四(如图25和图26所示)
与实施例三的区别在于:卡孔12’的周向边缘设有用于保护卡合件的翻边121’。
对于卡孔12’设在金属外壳10’上的实施例而言,在卡孔12’的周向边缘设置翻边121’,能够增加卡孔12’的深度,进而避免卡孔12’处太薄而过于锋利, 以防止跌落过程中金属外壳10’割伤绝缘件20’上的卡合件,对卡合件起到了保护作用。
实施例五(如图27至图31所示)
与实施例三的区别在于:卡合件包括多个弹性卡扣40’,多个弹性卡扣40’相背设置,围设出弹性柱扣。
卡合件包括多个弹性卡扣40’,多个弹性卡扣40’相背设置,并围设出弹性柱扣,则安装时,多个弹性卡扣40’被卡孔12’侧壁挤压而相互靠近,使弹性柱扣的直径变小;当绝缘件20’与金属外壳10’压合到位时,多个弹性卡扣40’的端部凸出于卡孔12’,并恢复形变,使弹性柱扣的直径大于卡孔12’而钩在金属外壳10’上,从而把金属外壳10’紧紧卡住,实现与绝缘件20’之间的卡接,结构简单,装配快捷。
实施例六(如图32至图36所示)
与实施例三的区别在于:卡合件包括带径向通孔51’的连接柱50’和与径向通孔51’相适配的弹簧插销60’;其中,连接柱50’贯穿卡孔12’,且弹簧插销60’贯穿径向通孔51’,并卡在连接柱50’上。
卡合件包括连接柱50’和弹簧插销60’,连接柱50’上设有径向通孔51’,安装时,先将连接柱50’穿过通孔70’,待绝缘件20’和金属外壳10’压合到位后,将弹簧插销60’穿过径向通孔51’,则弹簧插销60’卡在连接柱50’上,避免了连接柱50’脱出通孔70’,实现了金属外壳10’与绝缘件20’之间的卡接,同样结构简单,装配快捷。
上述四个实施例中(实施例三至实施例六),优选地,卡合件设在绝缘件20’上,卡孔12’设在金属外壳10’上,这样,一方面卡合件和卡孔12’的具体配合结构可以隐藏在外壳组件的内部,而不会暴露在外,使得外壳组件的外观更加平整,从而进一步提高了烹饪器具的美观度;另一方面,相较于在绝缘件20’上设置卡孔12’的方案而言,在绝缘件20’上设置卡合件,有利于提高绝缘件20’的强度,以提高绝缘件20’的使用寿命。
实施例七(如图37至图40所示)
金属外壳10’上设有通孔70’,绝缘件20’上设有能够产生塑性变形的连接柱50’;其中,连接柱50’贯穿通孔70’,且连接柱50’凸出通孔70’的部分变形 成为截面尺寸大于通孔70’尺寸的限位凸块52’,限位凸块52’抵靠在金属外壳10’上,使绝缘件20’与金属外壳10’固定相连。
金属外壳10’上设有通孔70’,绝缘件20’上设有连接柱50’,安装时,先将连接柱50’穿过通孔70’,待绝缘件20’与金属外壳10’压合到位后,采用热焊工艺或超声波焊等工艺将连接柱50’凸出于通孔70’的部分焊平使其贴近金属外壳10’,冷却后,连接柱50’凸出于通孔70’的部分则形成限位凸块52’,由于限位凸块52’的尺寸大于通孔70’的尺寸,因而能够抵靠在金属外壳10’上,把金属外壳10’紧紧卡住,实现金属外壳10’与绝缘件20’之间的固定连接。
实施例八(如图41至图43所示)
绝缘件20’上设有通孔70’,金属外壳10’上设有能够产生塑性变形的连接柱50’;其中,连接柱50’贯穿通孔70’,且连接柱50’凸出通孔70’的部分变形成为截面尺寸大于通孔70’尺寸的限位凸块52’,限位凸块52’抵靠在绝缘件20’上,使绝缘件20’与金属外壳10’固定相连。
优选地,连接柱50’为空心连接柱50’。
绝缘件20’上设有通孔70’,金属外壳10’上设有连接柱50’,安装时,先将连接柱50’穿过通孔70’,待绝缘件20’与金属外壳10’压合到位后,然后采用冲床或其他工具把连接柱50’凸出通孔70’的部分墩平或者冲压变形,形成尺寸大于通孔70’尺寸的限位凸块52’,则限位凸块52’抵靠在绝缘件20’上把绝缘件20’紧紧卡住,使绝缘件20’和金属外壳10’形成一个稳定的整体。
优选地,对于连接柱50’设在金属外壳10’上的实施例而言,将连接柱50’设计成空心的,是因为空心的金属连接柱50’相较于实心的金属连接柱50’,更易产生塑性变形,因此能够降低加工难度,提高生产效率。
实施例九(如图44和图45所示)
绝缘件20’和金属外壳10’上均设有通孔70’,紧固件穿过绝缘件20’和金属外壳10’上的通孔70’,使绝缘件20’与金属外壳10’固定相连。
绝缘件20’和金属外壳10’上均设有通孔70’,紧固件穿过通孔70’,将绝缘件20’和金属外壳10’固定连接在一起,形成一个稳定的整体,十分可靠。具体地,紧固件可以为螺钉、铆钉80’等单个部件,也可以为螺钉螺母、螺柱螺母等组合件,在此不再一一列举。
实施例十(如图46至图49所示)
金属外壳10’和绝缘件20’中的一个上设有锯齿状的通孔70’,另一个上设有连接柱50’,连接柱50’贯穿通孔70’并限位在通孔70’中,使绝缘件20’与金属外壳10’固定相连。
金属外壳10’上设有锯齿状的通孔70’,绝缘件20’上设有连接柱50’(空心的或实心的),先将连接柱50’穿过通孔70’,待绝缘件20’与金属外壳10’压合到位后,利用锯齿状钣金的利边与绝缘件20’上连接柱50’的过盈配合和/或锯齿状钣金与连接柱50’(空心的)发生弹性形变形成的预紧力,从而把绝缘件20’紧紧卡住,使金属外壳10’与绝缘件20’相互配合成一个稳定的整体。
或者,金属外壳10’上设有连接柱50’,绝缘件20’上设有锯齿状的通孔70’,先将连接柱50’穿过通孔70’,待绝缘件20’与金属外壳10’压合到位后,利用连接柱50’与通孔70’的过盈配合和/或绝缘件20’上通孔70’发生弹性形变形成的预紧力,从而把绝缘件20’紧紧卡住,也能使金属外壳10’与绝缘件20’相互配合形成一个稳定的整体。
优选地,锯齿状的通孔70’设在金属外壳10’上,连接柱50’设在绝缘件20’上,这样,一方面连接柱50’和通孔70’的具体配合结构可以隐藏在外壳组件的内部,而不会暴露在外,使得外壳组件的外观更加平整,从而进一步提高了烹饪器具的美观度;另一方面,相较于在绝缘件20’上设置通孔70’的方案而言,在绝缘件20’上设置连接柱50’有利于提高绝缘件20’的强度,以提高绝缘件20’的使用寿命。
实施例十一(如图50至图53所示)
金属外壳10’上设有折板14’,绝缘件20’上设有与折板14’相适配的连接孔90’,折板14’穿过连接孔90’后扣在绝缘件20’上,使绝缘件20’与金属外壳10’固定相连。
优选地,绝缘件20’上还设有凸台21’,凸台21’位于连接孔90’的边缘,折板14’先弯折压在凸台21’上,再弯折压在绝缘件20’上。
金属外壳10’上设有折板14’,绝缘件20’上设有连接孔90’,先将折板14’穿过连接孔90’,然后将折板14’弯折,使其扣在绝缘件20’上,则折板14’形成了类似L形卡扣30’的结构,实现了绝缘件20’与金属外壳10’之间的固定连 接。
在连接孔90’的边缘设置凸台21’,折板14’先弯折压在凸台21’上,再弯折压在绝缘件20’上,则L形折板14’在绝缘件20’上形成了内扣的结构,这一方面能够避免折板14’刮伤用户,另一方面凸台21’对折板14’起到了限位作用,降低了折板14’发生移动的概率,从而进一步确保了绝缘件20’与外壳之间的可靠连接。
实施例十二(如图54至图57所示)
金属外壳10’位于缺口11’两侧的边缘弯折形成两个开口朝向相反的第一轨道槽15’,绝缘件20’的两端弯折形成两个开口朝向相反的第二轨道槽22’,两个第一轨道槽15’与两个第二轨道槽22’相钩接,使绝缘件20’与金属外壳10’固定相连。
优选地,两个第一轨道槽15’的开口背离缺口11’,两个第二轨道槽22’的开口朝向缺口11’。
优选地,第一轨道槽15’和第二轨道槽22’中的一个的自由端设有折边16’,折边16’抵靠在第一轨道槽15’和第二轨道槽22’中的另一个上。
金属外壳10’的断开处弯折形成两个第一轨道槽15’,绝缘件20’的两端弯折形成两个第二轨道槽22’,第一轨道槽15’和第二轨道槽22’的横截面均大致呈n形,相互钩接,即可使绝缘件20’和金属外壳10’形成稳定的整体。具体地,绝缘件20’可以位于金属外壳10’的外侧,也可以位于金属外壳10’的内侧。
第一轨道槽15’的开口背离缺口11’,第二轨道槽22’的开口朝向缺口11’,结构更加简单,且两个第二轨道槽22’朝向相对,形成两个朝向相对的L形卡扣30’的结构,因而对金属外壳10’的两个断开端起到了一定的聚拢作用,能够进一步提高其连接可靠性。
第一轨道槽15’和第二轨道槽22’中的一个的自由端还设有折边16’,则折边16’抵靠在另一个轨道槽的内壁面上,起到了限位作用,能够避免第一轨道槽15’和第二轨道槽22’脱轨,从而进一步提高了绝缘件20’和金属外壳10’的连接可靠性。
在上述实施例三至实施例十二中,缺口11’沿金属外壳10’的周向方向上的宽度a’大于或等于2mm,如图16、图18和图19所示。
使缺口11’沿金属外壳10’的周向方向上的宽度a’大于或等于2mm,是为了保证金属外壳10’的断开处具有一定的间距,以避免间距过小导致断开处产生火花、发热等情况,从而保证了产品的安全性和使用可靠性。
在上述实施例三至实施例十二中,金属外壳10’的尾部顶端设有安装槽17’,缺口11’的数量为一个,且缺口11’位于安装槽17’的下方,并与安装槽17’相连通,如图16至图57所示。
由于一个缺口11’即可保证外壳组件不会形成电路上的闭环回路,因此只设置一个缺口11’即可实现本发明的目的;且一个缺口11’能够将绝缘件20’的数量降至最低,从而及节约了成本,又提高了生产效率。而将缺口11’开设在金属外壳10’的尾部,一方面使得缺口11’和绝缘件20’位于烹饪器具不常见的位置处,从而提高了烹饪器具整体的美观度;另一方面,金属外壳10’的尾部一般设有用于安装铰链或与烹饪器具的其他结构相适配的安装槽17’,将缺口11’设在此处,能够相对减小缺口11’的尺寸,从而进一步提高了产品的美观度。
至于缺口11’的具体高度b’(沿金属外壳10’轴线方向)和具体宽度a’(沿金属外壳10’周向方向,优选大于或等于2mm),可以根据产品的结构进行调整。
当然,缺口11’的数量也可以为多个,多个缺口11’处均用绝缘件20’连接起来,同样也能够实现本发明的目的,因此也在本发明的保护范围内;缺口11’的数量为一个时,也可以开设在金属外壳10’的其他部位,本领域的技术人员应当理解,这些实施例均应在本发明的保护范围内。
在上述实施例三至实施例十二中,缺口11’呈方形,如图16至图57所示。
缺口11’呈方形(长方形或正方形),既便于加工成型,又便于与绝缘件20’的装配,且形状规则,较为美观。当然,缺口11’的形状不限于上述方形,也可以是其他形状,在此不再一一列举,但都应在本发明的保护范围内。
在上述实施例三至实施例十二中,绝缘件20’上设有与缺口11’相适配的定位筋23’,如图16至图26所示。
绝缘件20’上设有与缺口11’相适配的定位筋23’,能够用于装配时防呆。具体地,在装配时,可以先将定位筋23’插入缺口11’内,这样能够确定绝缘件20’与金属外壳10’的相对位置关系,起到定位的作用,使金属外壳10’和绝 缘件20’相互连接的部位(比如:卡扣和卡孔12’)能够迅速对准,从而也提高了外壳组件的装配效率。
优选地,定位筋23’的数量为多个,且多个定位筋23’沿金属外壳10’的轴线方向平行排布。
由于缺口11’贯穿了金属外壳10’的轴线方向,因而具有一定的高度,故而设置多个定位筋23’,使其沿金属外壳10’的轴线方向平行排布,能够与缺口11’的多个部位相适配,因而定位更为准确。具体地,多个定位筋23’的高度可以相同,也可以不同,相邻的定位筋23’之间的距离,可以相同,也可以不同。
在上述实施例三至实施例十中,金属外壳10’位于缺口11’的两侧的部分向内凹陷,形成与绝缘件20’的尺寸相适配的下沉台阶18’,使绝缘件20’的外表面与金属外壳10’的外表面相平齐,如图16至图49所示。
在金属外壳10’上设置下沉台阶18’,能够使绝缘件20’的外表面与金属外壳10’的外表面相平齐,从而提高了外壳组件的美观度,进而提升了烹饪器具的档次。
在上述实施例三至实施例十二中,简单的将绝缘件20’分开为两件或两件以上,沿金属外壳的高度方向依次排列,即:一个绝缘件20’包括多个沿金属外壳高度方向依次排列的子绝缘件,由于该技术方案没有脱离本发明的设计思想和宗旨,因而也应属于本发明的保护范围。
如图58至图89所示,在本发明的另一些实施例中,所述绝缘件的数量为多个,多个所述绝缘件包括第一绝缘件和第二绝缘件,所述第一绝缘件和所述第二绝缘件连接所述金属外壳的断开端,并覆盖所述缺口,使所述外壳组件呈闭环的断路结构。
在这些实施例中,通过把金属外壳10”断开,用绝缘件将其断开处连接起来,使得外壳组件在电路上是断开的,从而可以减弱金属外壳10”对磁场的感应,以降低温升,解决了现有技术中金属外壳10”形成闭环回路导致容易感应线圈盘产生的磁场而发热致使温升过高的问题;且两个绝缘件连接金属外壳10”的断开处,并覆盖缺口11”,使外壳组件形成闭环结构,则保证了外壳组件的完整性,进而保证了烹饪器具的外观;此外,一个缺口11”处安装两个绝 缘件,两个绝缘件对缺口11”起到了双重覆盖的作用,从而确保了外壳组件的完整性,并与金属外壳10”实现了双重连接,从而确保了外壳组件的强度。
可以理解的是,一个缺口11”对应金属外壳10”的两个断开端,故而一个缺口11”处的绝缘件应该与该缺口11”处的金属外壳10”的两个断开端相连,以保证外壳组件形成完整的环状结构。
可选地,第一绝缘件20”和第二绝缘件30”位于金属外壳10”内外两侧的不同侧,如图58至图89所示。
可选地,第一绝缘件20”和第二绝缘件30”位于金属外壳10”的同一侧,且第二绝缘件30”位于第一绝缘件20”和金属外壳10”之间。
第一绝缘件20”和第二绝缘件30”位于金属外壳10”内外两侧的不同侧,即:两个绝缘件分别位于金属外壳10”的内侧和外侧,具体可以是第一绝缘件20”在内,第二绝缘件30”在外,也可以是第一绝缘件20”在外,第二绝缘件30”在内,这样,两个绝缘件分别从内侧和外侧对缺口11”进行覆盖并与金属外壳10”的断开端连接在一起,进一步确保了外壳组件的完整性和强度;且可以避免两个绝缘件位于缺口11”的同一侧导致缺口11”处过厚的问题,有利于提高外壳组件的美观度。
当然,两个绝缘件也可以位于金属外壳10”的同一侧,即:均位于金属外壳10”的内侧,或均位于金属外壳10”的内侧,同样能够实现本发明的目的。具体地,当两个绝缘件均位于金属外壳10”的内侧时,第一绝缘件20”位于最内侧,以保证第二绝缘件30”能够位于第一绝缘件20”和金属外壳10”之间;当两个绝缘件均位于金属外壳10”的外侧时,第一绝缘件20”位于最外侧,以保证第二绝缘件30”能够位于第一绝缘件20”和金属外壳10”之间。
下面结合一些具体实施例来详细描述本申请中金属外壳10”与第一绝缘件20”、第二绝缘件30”的装配结构。
实施例十三(如图58至图62所示)
第一绝缘件20”上设有卡合件,金属外壳10”和第二绝缘件30”上分别设有第一卡孔12”和第二卡孔31”,卡合件与第一卡孔12”和第二卡孔31”相配合,使第一绝缘件20”和第二绝缘件30”卡接在金属外壳10”上。
其中,卡合件为L形卡扣21”,L形卡扣21”穿过第一卡孔12”和第二卡 孔31”,并扣合在金属外壳10”和第二绝缘件30”中远离第一绝缘件20”的一个上。
上述实施例中,通过卡合件与第一卡孔12”、第二卡孔31”的配合,使金属外壳10”与两个绝缘件卡接在一起,既保证了金属外壳10”与两个绝缘件之间的固定连接,且使得装配过程更加简单快捷,有利于提高装配效率。进一步地,如前,一个绝缘件与金属外壳10”的两个断开端相连,故而卡合件和卡孔优选都是两组,分别位于缺口11”的两侧,以保证两个绝缘件与金属外壳10”之间的可靠连接。
具体地,对于两个绝缘件位于金属外壳10”的同一侧的实施例而言,卡合件先穿过第二绝缘件30”上的第二卡孔31”,再穿过金属外壳10”上的第一卡孔12”;而对于两个绝缘件分别位于金属外壳10”的内外两侧的实施例而言,卡合件则先穿过金属外壳10”上的第一卡孔12”,再穿过第二绝缘件30”上的第一卡孔12”。
卡合件为L形卡扣21”,即卡合件呈单边钩状,安装时,先将L形卡扣21”穿过第一卡孔12”和第二卡孔31”,待两个绝缘件和金属外壳10”压合到位后,沿着L形卡扣21”的弯折方向推动L形卡扣21”,直至L形卡扣21”的一端抵靠在卡孔的孔壁上,此时,L形卡扣21”的另一端即抵靠在金属外壳10”(两个绝缘件位于金属外壳10”的同一侧时)或第二绝缘件30”(两个绝缘件分别位于金属外壳10”的内外两侧时)上,实现了金属外壳10”与两个绝缘件之间的卡接。
进一步地,L形卡扣21”的数量为多个,并分为两组,两组L形卡扣21”分别位于缺口11”的两侧;其中,两组L形卡扣21”朝向相同的方向,如图58所示;或,两组L形卡扣21”均朝向缺口11”。
L形卡扣21”的数量为多个,能够进一步确保金属外壳10”与两个绝缘件之间的可靠连接;两组L形卡扣21”朝向相同的方向,如:一致向上、一致向下、一致向左、一致向右等,便于所有的L形卡扣21”同步装配,以实现一步安装到位;两组L形卡扣21”均朝向缺口11”,即两组L形卡扣21”的朝向相对,则装配到位时,由于金属外壳10”的两个断开端有向两侧分开的趋势,恰好与L形卡扣21”的脱出方向相反(两个断开端相互靠近时,L形卡扣21” 才能脱出),故而L形卡扣21”不易脱出卡孔,连接更加可靠。
优选地,每组L形卡扣21”中,至少一个L形卡扣21”的尾部设有倒刺211”,金属外壳10”和第二绝缘件30”中远离第一绝缘件20”的一个设有卡槽32”(如图62所示)或凸包,倒刺211”卡入卡槽32”内或钩在凸包上。
倒刺211”与卡槽32”或凸包相配合,对L形卡扣21”起到了限位作用,能够避免L形卡扣21”反向滑动导致绝缘件脱落,从而进一步确保了金属外壳10”与绝缘件的可靠连接。
实施例十四(如图63至图67所示)
与实施例十三的区别在于:卡合件包括多个弹性卡扣22”,多个弹性卡扣22”相背设置,围设出弹性柱扣,如图63所示。
卡合件包括多个弹性卡扣22”,多个弹性卡扣22”相背设置,并围设出弹性柱扣,则安装时,多个弹性卡扣22”被两个卡孔的侧壁挤压而相互靠近,使弹性柱扣的直径变小;当两个绝缘件与金属外壳10”压合到位时,多个弹性卡扣22”的端部凸出于两个卡孔,并恢复形变,使弹性柱扣的直径大于两个卡孔而钩在金属外壳10”(两个绝缘件位于金属外壳10”的同一侧时)或第二绝缘件30”(两个绝缘件分别位于金属外壳10”的内外两侧时)上,从而把金属外壳10”紧紧卡住,实现与两个绝缘件之间的卡接,结构简单,装配快捷。
实施例十五(如图68至图73所示)
与实施例十三的区别在于:卡合件包括带径向通孔231”的连接柱23”和与径向通孔231”相适配的弹簧插销24”,如图68所示;其中,连接柱23”贯穿第一卡孔12”和第二卡孔31”,且弹簧插销24”贯穿径向通孔231”,并卡在连接柱23”上,如图73所示。
卡合件包括连接柱23”和弹簧插销24”,连接柱23”上设有径向通孔231”,安装时,先将连接柱23”穿过第一卡孔12”和第二卡孔31”,待两个绝缘件和金属外壳10”压合到位后,将弹簧插销24”穿过径向通孔231”,则弹簧插销24”卡在连接柱23”上,避免了连接柱23”脱出两个卡孔,实现了金属外壳10”与两个绝缘件之间的卡接,同样结构简单,装配快捷。
实施例十六(如图74至图79所示)
第一绝缘件20”上设有能够产生塑性变形的连接柱23”,金属外壳10”和 第二绝缘件30”上分别设有第一通孔17”和第二通孔35”,如图74所示;其中,连接柱23”贯穿第一通孔17”和第二通孔35”,且连接柱23”凸出第一通孔17”和第二通孔35”的部分变形成为截面尺寸大于第一通孔17”和第二通孔35”中远离第一绝缘件20”的一个的尺寸的限位凸块232”,如图78和图79所示,限位凸块232”抵靠在金属外壳10”和第二绝缘件30”中远离第一绝缘件20”的一个上,使第一绝缘件20”、第二绝缘件30”与金属外壳10”固定相连。
第一绝缘件20”上设有连接柱23”,金属外壳10”和第二绝缘件30”上分别设有第一通孔17”和第二通孔35”,安装时,先将连接柱23”穿过第一通孔17”和第二通孔35”,待两个绝缘件与金属外壳10”压合到位后,采用热焊工艺或超声波焊等工艺将连接柱23”凸出于两个通孔的部分焊平使其贴近金属外壳10”或第二绝缘件30”,冷却后,连接柱23”凸出于两个通孔的部分则形成限位凸块232”,由于限位凸块232”的尺寸大于通孔的尺寸,因而能够抵靠在金属外壳10”或第二绝缘件30”上,把金属外壳10”紧紧卡住,实现金属外壳10”与两个绝缘件之间的固定连接。
具体地,当两个绝缘件位于金属外壳10”的同一侧时,连接柱23”先穿过第二绝缘件30”上的第二通孔35”,再穿过金属外壳10”上的第一通孔17”,最后形成的限位凸块232”的尺寸大于第一通孔17”的尺寸,以使限位凸块232”抵靠在金属外壳10”上,保证金属外壳10”与两个绝缘件之间的固定连接;当两个绝缘件位于金属外壳10”的不同侧时,连接柱23”先穿过金属外壳10”上的第一通孔17”,再穿过第二绝缘件30”上的第二通孔35”,最后形成的限位凸块232”的尺寸大于第二通孔35”的尺寸,以使限位凸块232”抵靠在第二绝缘件30”上,保证金属外壳10”与两个绝缘件之间的固定连接。
实施例十七(如图80至图84所示)
第一绝缘件20”、金属外壳10”和第二绝缘件30”上分别设有第一连接孔25”、第二连接孔13”和第三连接孔33”,紧固件穿过第一连接孔25”、第二连接孔13”和第三连接孔33”,使第一绝缘件20”、第二绝缘件30”与金属外壳10”固定相连,如图80、图83和图84所示。
两个绝缘件和金属外壳10”上均设有连接孔,紧固件穿过连接孔,将两个 绝缘件和金属外壳10”固定连接在一起,形成一个稳定的整体,十分可靠。具体地,紧固件可以为螺钉、铆钉40”等单个部件,也可以为螺钉螺母、螺柱螺母等组合件,在此不再一一列举。
实施例十八(如图85至图89所示)
第一绝缘件20”和第二绝缘件30”中的至少一个上设有胶水槽26”,第一绝缘件20”、第二绝缘件30”与金属外壳10”通过胶黏剂粘接在一起,如图85和图89所示。
优选地,第一绝缘件20”上设有定位柱27”,如图85和图88所示,金属外壳10”和第二绝缘件30”上分别设有第一定位孔14”和第二定位孔34”,定位柱27”贯穿第一定位孔14”和第二定位孔34”。
通过胶粘的方式,同样能够方便地实现两个绝缘件与金属外壳10”之间的固定连接,且价格低廉,装配方便;而胶水槽26”的设置,既保证了能够施加足够的胶黏剂,以保证粘接强度,且便于将两个绝缘件与金属外壳10”紧密贴合在一起,避免产生缝隙或胶黏剂溢出等情况,有利于提高产品的美观度。
具体地,当两个绝缘件位于金属外壳10”的同一侧时,两个绝缘件之间通过胶黏剂粘接,第二绝缘件30”与金属外壳10”之间也通过胶黏剂粘接在一体;当两个绝缘件位于金属外壳10”的不同侧时,胶水槽26”优选与缺口11”相连通,这样可以仅在一个绝缘件上开设胶水槽26”,即可保证胶黏剂能够将三个部件粘接在一起。
第一绝缘件20”上的定位柱27”贯穿第一定位孔14”和第二定位孔34”后,一方面对三个部件起到了有效的定位作用,保证了三个部件的相对位置关系,能够用于装配时防呆;另一方面,还限制了三个部件沿金属外壳10”的周向或轴向发生相对运动,从而进一步提高了外壳组件的连接强度和稳定性。
在上述实施例十三至实施例十八中,优选地,沿金属外壳10”的径向,第一绝缘件20”位于第二绝缘件30”的外侧,如图58至图89所示。
沿金属外壳10”的径向,第一绝缘件20”位于第二绝缘件30”的外侧,则对于两个绝缘件位于金属外壳10”的同一侧且第二绝缘件30”位于金属外壳10”和第一绝缘件20”之间的实施例而言,两个绝缘件优选均位于金属外壳10”的外侧;对于两个绝缘件位于金属外壳10”的不同侧的实施例而言,优选 第一绝缘件20”位于金属外壳10”的外侧,第二绝缘件30”位于金属外壳10”的内侧。这样,均保证了第一绝缘件20”位于金属外壳10”的最外侧,因此可以将两个绝缘件与金属外壳10”的具体装配结构隐藏在外壳组件的内部,而不会暴露在外,使得外壳组件的外观更加平整,从而进一步提高了烹饪器具的美观度。
在上述实施例十三至实施例十八中,缺口11”沿金属外壳10”的周向方向上的宽度大于或等于2mm。
使缺口11”沿金属外壳10”的周向方向上的宽度大于或等于2mm,是为了保证金属外壳10”的断开处具有一定的间距,以避免间距过小导致断开处产生火花、发热等情况,从而保证了产品的安全性和使用可靠性。
在上述实施例十三至实施例十八中,金属外壳10”的尾部顶端设有安装槽16”,缺口11”的数量为一个,且缺口11”位于安装槽16”的下方,并与安装槽16”相连通,如图58至图89所示。
由于一个缺口11”即可保证外壳组件不会形成电路上的闭环回路,因此只设置一个缺口11”即可实现本发明的目的;且一个缺口11”能够将绝缘件的数量降至最低,从而及节约了成本,又提高了生产效率。而将缺口11”开设在金属外壳10”的尾部,一方面使得缺口11”和绝缘件位于烹饪器具不常见的位置处,从而提高了烹饪器具整体的美观度;另一方面,金属外壳10”的尾部一般设有用于安装铰链或与烹饪器具的其他结构相适配的安装槽16”,将缺口11”设在此处,能够相对减小缺口11”的尺寸,从而进一步提高了产品的美观度。
至于缺口11”的具体高度(沿金属外壳10”轴线方向)和具体宽度(沿金属外壳10”周向方向,优选大于或等于2mm),可以根据产品的结构进行调整。
当然,缺口11”的数量也可以为多个,多个缺口11”处均用绝缘件连接起来,同样也能够实现本发明的目的,因此也在本发明的保护范围内;缺口11”的数量为一个时,也可以开设在金属外壳10”的其他部位,本领域的技术人员应当理解,这些实施例均应在本发明的保护范围内。
在上述实施例十三至实施例十八中,缺口11”呈方形,如图58至图89所示。
缺口11”呈方形(长方形或正方形),既便于加工成型,又便于与绝缘件的装配,且形状规则,较为美观。当然,缺口11”的形状不限于上述方形,也可以是其他形状,在此不再一一列举,但都应在本发明的保护范围内。
在上述任一实施例中,金属外壳10”位于缺口11”的两侧的部分向内凹陷,形成与第一绝缘件20”和/或第二绝缘件30”的尺寸相适配的下沉台阶15”,如图58至图89所示,使第一绝缘件20”或第二绝缘件30”的外表面与金属外壳10”的外表面相平齐。
在金属外壳10”上设置下沉台阶15”,能够使第一绝缘件20”(第一绝缘件20”位于最外侧时)或第二绝缘件30”(第二绝缘件30”位于最外侧时)的外表面与金属外壳10”的外表面相平齐,从而提高了外壳组件的美观度,进而提升了烹饪器具的档次。
如图90至图96所示,本发明第二方面的实施例提供的外壳组件,用于电磁感应加热的烹饪器具,外壳组件套设在烹饪器具的内胆的外侧,外壳组件包括:底座30”’、外壳罩40”’、金属外壳10”’和遮挡片20”’。
具体地,外壳罩40”’位于底座30”’的上方;金属外壳10”’设置在底座30”’和外壳罩40”’之间,并与底座30”’和外壳罩40”’相连,金属外壳10”’整体呈断开的环状,且金属外壳10”’的断开处形成缺口11”’;遮挡片20”’为绝缘件,且遮挡片20”’覆盖缺口11”’,以与金属外壳10”’形成闭环的断路结构。
本发明第二方面的实施例提供的外壳组件,通过把金属外壳10”’断开,用绝缘的遮挡片20”’将金属外壳10”’断开的部分遮挡起来,使得外壳组件在电路上是断开的,从而可以减弱金属外壳10”’对磁场的感应,以降低温升,解决了现有技术中金属外壳10”’形成闭环回路导致容易感应线圈盘产生的磁场而发热致使温升过高的问题;且金属外壳10”’与底座30”’和外壳罩40”’相连,即金属外壳10”’限位在底座30”’和外壳罩40”’之间,保证了金属外壳10”’的断开端不会脱落,而遮挡片20”’覆盖金属外壳10”’的缺口11”’,保证了外壳组件的完整性,进而保证了烹饪器具的外观。
进一步地,金属外壳10”’的上端和下端设有卷边14”’,外壳罩40”’上和底座30”’上分别设有第一限位槽31”’和第二限位槽41”’,卷边14”’嵌入第一限位槽31”’和第二限位槽41”’中,使金属外壳10”’夹持固定在外壳罩40”’ 和底座30”’之间。
将金属外壳10”’上端和下端的卷边14”’分别嵌入外壳罩40”’上的第一限位槽31”’和底座30”’上的第二限位槽41”’中,即可将金属外壳10”’夹持在外壳罩40”’和底座30”’之间,使底座30”’、金属外壳10”’和外壳罩40”’装配成一个稳定的整体,装配过程十分便捷;且能够尽可能减少在底座30”’、金属外壳10”’和外壳罩40”’上打孔,从而既提高了装配效率,又提高了三者的强度。
在上述实施例中,优选地,如图90所示,缺口11”’沿金属外壳10”’的周向方向上的宽度a”’大于或等于2mm。
使缺口11”’沿金属外壳10”’的周向方向上的宽度a”’大于或等于2mm,是为了保证金属外壳10”’的断开处具有一定的间距,以避免间距过小导致断开处产生火花、发热等情况,从而保证了产品的安全性和使用可靠性。
优选地,如图90和图94所示,金属外壳10”’的尾部顶端设有安装槽12”’,缺口11”’的数量为一个,且缺口11”’位于安装槽12”’的下方,并与安装槽12”’相连通。
由于一个缺口11”’即可保证外壳组件不会形成电路上的闭环回路,因此只设置一个缺口11”’即可实现本发明的目的;且一个缺口11”’能够将遮挡片20”’的数量降至最低,从而及节约了成本,又提高了生产效率。而将缺口11”’开设在金属外壳10”’的尾部,一方面使得缺口11”’和遮挡片20”’位于烹饪器具不常见的位置处,从而提高了烹饪器具整体的美观度;另一方面,金属外壳10”’的尾部一般设有用于安装铰链或与烹饪器具的其他结构相适配的安装槽12”’,将缺口11”’设在此处,能够相对减小缺口11”’的尺寸,从而进一步提高了产品的美观度。
至于缺口11”’的具体高度(沿金属外壳10”’轴线方向)和具体宽度(沿金属外壳10”’周向方向,优选大于或等于2mm),可以根据产品的结构进行调整。
当然,缺口11”’的数量也可以为多个,多个缺口11”’处均用遮挡片20”’连接起来,同样也能够实现本发明的目的,因此也在本发明的保护范围内;缺口11”’的数量为一个时,也可以开设在金属外壳10”’的其他部位,本领域的 技术人员应当理解,这些实施例均应在本发明的保护范围内。
优选地,缺口11”’呈方形,如图90和图94所示。
缺口11”’呈方形(长方形或正方形),既便于加工成型,又便于与遮挡片20”’的装配,且形状规则,较为美观。当然,缺口11”’的形状不限于上述方形,也可以是其他形状,在此不再一一列举,但都应在本发明的保护范围内。
在上述第二方面的实施例中,可选地,遮挡片20”’与底座30”’固定连接。
可选地,遮挡片20”’与底座30”’为一体式结构,如图90、图91、图93、图94、图95和图96所示。
可选地,遮挡片20”’与外壳罩40”’固定连接。
可选地,遮挡片20”’与外壳罩40”’为一体式结构。
遮挡片20”’与底座30”’固定连接(如通过螺钉、铆钉50”’等紧固件连接在一起)或为一体式结构(如通过注塑一体成型),即:遮挡片20”’长在底座30”’上,由下向上伸出,则装配时,直接将底座30”’、金属外壳10”’和外壳罩40”’装配到位,保证金属外壳10”’固定在底座30”’和外壳罩40”’之间,此时向上突出的遮挡片20”’恰好位于金属外壳10”’的缺口11”’处,将缺口11”’遮挡起来,十分便捷;同时,遮挡片20”’从底座30”’长出,不易脱落,因此无需再对遮挡片20”’与金属外壳10”’进行单独固定,即可保证遮挡片20”’与金属外壳10”’的稳定配合,从而提高了装配效率;此外,遮挡片20”’与底座30”’一体成型还可以省去遮挡片20”’与底座30”’的装配工序,进一步提高了装配效率。
同理,遮挡片20”’与外壳罩40”’固定连接(如通过紧固件连接在一起)或为一体式结构(如通过注塑一体成型),即:遮挡片20”’固定在外壳罩40”’上,由上向下伸出,则装配时,直接将底座30”’、金属外壳10”’和外壳罩40”’装配到位,保证金属外壳10”’固定在底座30”’和外壳罩40”’之间,此时向下突出的遮挡片20”’恰好位于金属外壳10”’的缺口11”’处,将缺口11”’遮挡起来,也十分便捷;同时,遮挡片20”’从外壳罩40”’长出,不易脱落,因此无需再对遮挡片20”’与金属外壳10”’进行单独固定,即可保证遮挡片20”’与金属外壳10”’的稳定配合,从而提高了装配效率;此外,遮挡片20”’与外壳罩40”’为一体式结构时,还可以省去遮挡片20”’与外壳罩40”’的装配工序,进 一步提高了装配效率。
在上述第二方面的实施例中,可选地,遮挡片20”’粘接在金属外壳10”’上。
可选地,遮挡片20”’通过紧固件固定在金属外壳10”’上,如图94至图96所示。
利用类似铭牌的包装物粘贴在金属外壳10”’的断开处,即可将缺口11”’遮挡起来,从而实现本发明的目的,则该类似铭牌的包装物即充当了遮挡片20”’,而该包装物成本较低,且便于设计成各种更为美观的包装物,因此也有利于进一步提高产品的美观度。
当然,也可以采用螺钉、铆钉50”’等紧固件将遮挡片20”’固定在金属外壳10”’上,这保证了遮挡片20”’与金属外壳10”’之间的稳定连接,确保了遮挡片20”’不会发生脱落导致金属外壳10”’的缺口11”’暴露出来,从而进一步提高了产品的使用可靠性。
可以理解的是,遮挡片20”’无论是粘贴在金属外壳10”’上,还是通过紧固件固定外金属外壳10”’上,与遮挡片20”’和底座30”’或外壳的连接关系无关,即:这两种方案下,遮挡片20”’可以与底座30”’或外壳罩40”’固定连接/一体成型,也可以是单独的部件,仅与遮挡片20”’固定相连。
在上述第二方面的实施例中,金属外壳10”’夹持在底座30”’和外壳罩40”’之间,且底座30”’与外壳罩40”’通过紧固件固定相连,如图90至图93所示。
可选地,金属外壳10”’与底座30”’通过紧固件固定连接,如图94至图96所示。
可选地,金属外壳10”’与外壳罩40”’通过紧固件固定连接。
对于金属外壳10”’的固定结构,可以直接将金属外壳10”’夹持在底座30”’和外壳罩40”’之间,并进一步利用紧固件将底座30”’与外壳罩40”’固定相连,这样是利用三者的装配关系,将金属外壳10”’固定在底座30”’和外壳罩40”’之间,保证三者的相对稳定;同时,底座30”’与外壳罩40”’之间还采用紧固件(如铆钉50”’、螺钉等紧固件或紧固组合)相连,是为了限制金属外壳10”’的断开端向外脱落,以进一步保证对金属外壳10”’的有效固定。
当然,也可以先利用紧固件把金属外壳10”’固定在底座30”’上,然后再把外壳罩40”’、金属外壳10”’和底座30”’三者装配在一起;或者,先利用紧固件把金属外壳10”’固定在外壳罩40”’上,然后再把三者装配在一体,都能够有效限制金属外壳10”’的断开端向外脱落,以保证对金属外壳10”’的有效固定。
值得说明的是,对于遮挡片20”’长在底座30”’或外壳罩40”’上的实施例而言,可以将紧固件的具体固定位置设置在遮挡片20”’和金属外壳10”’的断开端上,即:在金属外壳10”’的断开端和遮挡片20”’上分别开设连接孔,紧固件贯穿金属外壳10”’和遮挡片20”’上的连接孔,以实现金属外壳10”’与底座30”’或外壳罩40”’的固定连接;这一方面对金属外壳10”’的断开端进行了直接的固定,因而最为牢靠,同时也实现了金属外壳10”’与遮挡片20”’的固定连接,这样可以节约紧固件,以降低成本,并提高装配效率。
在上述第二方面的实施例中,可选地,遮挡片20”’位于金属外壳10”’的内侧。
在上述第二方面的实施例中,可选地,遮挡片20”’位于金属外壳10”’的外侧,如图90、图91、图92、图94、图95和图96所示。
无论遮挡片20”’位于金属外壳10”’的内侧还是外侧,都能够遮住缺口11”’,以保证外壳组件的完整性,因而均能够实现本发明的目的,均在本发明的保护范围内。
在上述实施例中,优选地,如图90和图94所示,金属外壳10”’位于缺口11”’的两侧的部分向内凹陷,形成与遮挡片20”’的尺寸相适配的下沉台阶13”’,使遮挡片20”’的外表面与金属外壳10”’的外表面相平齐。
对于遮挡片20”’位于金属外壳10”’的外侧的实施例而言,优选在金属外壳10”’上设置下沉台阶13”’,这样遮挡片20”’嵌入下沉台阶13”’内,能够使遮挡片20”’的外表面与金属外壳10”’的外表面相平齐,从而提高了外壳组件的美观度,进而提升了烹饪器具的档次。
下面结合两个具体实施例来详述本申请第二方面的实施例提供的外壳组件。
