Description
技术领域
本发明涉及锅具加工技术领域,尤其涉及一种快速导热的复合金属板及高压锅。
背景技术
高压锅又叫压力锅,压力煲,是一种厨房的锅具;压力锅通过液体在较高气压下沸点会提升这一物理现象,对水施加压力,使水可以达到较高温度而不沸腾,以加快炖煮食物的效率;高压锅可以将被蒸煮的食物加热到100℃以上,在高海拔地区,利用压力锅可避免水沸点降低而不易煮熟食物的问题。
高压锅的材料的要求很高,在能够抗高压的同时,锅底要求导热性能强,能够快速将热量传递到锅内,省时节能;但是锅身要求导热性能弱,防止锅内热量从锅身散发,起到保温节能作用。
单一的金属或合金很难满足高压锅整体的要求,因此经常使用多层复合金属板来制作高压锅。
发明内容
本发明针对现有技术的不足,提供了一种快速导热的复合金属板及高压锅。
本发明通过以下技术手段实现解决上述技术问题的:
一种快速导热的复合金属板,包括锅具内层、锅具外层以及设置在锅具内层和锅具外层之间的复合金属层;所述复合金属层包括圆形的导热层和设置在导热层外侧圆环状的隔热层;所述导热层采用铝材料或紫铜材料;所述隔热层采用玻璃纤维、陶瓷纤维或碳纤维中的一种或多种编织而成,所述锅具内层和锅具外层的直径大于隔热层外侧的直径。
所述锅具内层采用304不锈钢、316不锈钢或食品级钛材料中的一种;所述锅具外层采用430不锈钢。
所述导热层靠近锅具内层一侧设置有若干条上凹槽,所述锅具内层靠近导热层一侧设置有与上凹槽配合使用的上凸条;所述导热层靠近锅具外层一侧设置有若干条下凹槽,所述锅具外层靠近导热层一侧设置有与下凹槽配合使用的下凸条。
若干条所述上凹槽和上凸条设置为圆环状;
若干条所述下凹槽和下凸条设置为由导热层圆心向导热层圆边辐射状。
所述上凹槽的槽顶的宽度小于槽底的宽度,所述上凸条与锅具内层连接一侧的宽度小于另一侧的宽度;所述下凹槽的槽顶的宽度小于槽底的宽度,所述下凸条与锅具外层连接一侧的宽度小于另一侧的宽度。
所述锅具内层、锅具外层以及导热层通过热压钎焊连接,相邻的所述上凹槽之间设置有若干个通孔。
一种高压锅,由上述一种快速导热的复合金属板制成。
本发明的有益效果:通过在锅具内层和锅具外层之间设置包括导热层和隔热层的复合金属层,从而使得用复合金属板制得的高压锅的锅底具备良好的导热性,而锅身具备良好的隔热性,既保证高压锅快速升温、节能的同时具备保温的功能,锅身的隔热性能够使得锅身的温度远低于锅底,起到防烫的作用,同时防止高压锅内热量散失起到节能的作用。
玻璃纤维、陶瓷纤维和碳纤维具备良好的隔热性能的同时能够耐高温。方便加工成型以及高压锅后期使用;所述锅具内层和锅具外层的直径大于隔热层外侧的直径使得在用复合金属板制得的高压锅时,复合金属板边沿无隔热层区域封闭成高压锅的边沿,将隔热层封在腔内,提高隔热性能。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
需要说明的是,当元件被称为“固定于”另一个元件,它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件,它可以是直接连接到另一个元件或者可能同时存在居中元件。
实施例1
如图1所示,本实施例所述一种快速导热的复合金属板,包括锅具内层10、锅具外层20以及设置在锅具内层10和锅具外层20之间的复合金属层30;所述复合金属层30包括圆形的导热层31和设置在导热层31外侧圆环状的隔热层32;所述导热层31采用铝材料或紫铜材料;所述隔热层32采用玻璃纤维、陶瓷纤维或碳纤维中的一种或多种编织而成,所述锅具内层10和锅具外层20的直径大于隔热层32外侧的直径。
通过在锅具内层10和锅具外层20之间设置包括导热层31和隔热层32的复合金属层30,从而使得用复合金属板制得的高压锅的锅底具备良好的导热性,而锅身具备良好的隔热性,既保证高压锅快速升温、节能的同时具备保温的功能,锅身的隔热性能够使得锅身的温度远低于锅底,起到防烫的作用,同时防止高压锅内热量散失起到节能的作用。
玻璃纤维、陶瓷纤维和碳纤维具备良好的隔热性能的同时能够耐高温。方便加工成型以及高压锅后期使用;所述锅具内层10和锅具外层20的直径大于隔热层32外侧的直径使得在用复合金属板制得的高压锅时,复合金属板边沿无隔热层32区域封闭成高压锅的边沿,将隔热层32封在腔内,提高隔热性能。
所述锅具内层10采用304不锈钢、316不锈钢或食品级钛材料中的一种;所述锅具外层20采用430不锈钢;430不锈钢为铁素体不锈钢,且添加有钛元素,导热性能好,机械性能优,适用于锅具外层结构;304不锈钢、316不锈钢为奥氏体不锈钢,耐腐蚀性能好,更稳定,特别是耐盐水腐蚀,食品级钛材料的耐腐蚀性较304不锈钢、316不锈钢更优。
所述导热层31靠近锅具内层10一侧设置有若干条上凹槽33,所述锅具内层10靠近导热层31一侧设置有与上凹槽33配合使用的上凸条11;所述导热层31靠近锅具外层20一侧设置有若干条下凹槽34,所述锅具外层20靠近导热层31一侧设置有与下凹槽34配合使用的下凸条21。
通过设置上凸条11与上凹槽33配合以及下凹槽34与下凸条21配合,使得锅具内层10、锅具外层20以及导热层31之间连接更紧密,避免因材质热膨胀系数不同导致出现缝隙或分层,使得导热性能以及力学性能下降,锅具的使用寿命缩短;同时通过设置上凸条11与下凸条21起到加强筋的作用,从而提高锅具内层10与锅具外层20的强度和刚性,以提高高压锅的耐高压强度。
若干条所述上凹槽33和上凸条11设置为圆环状;若干条所述上凹槽33和上凸条11呈圆环状卡紧,使得在温度变化时,锅具内层10与导热层31之间因为热膨胀系数不同导致的形变隔绝在若干个相邻的圆环之间,避免因形变太大导致锅具内层10与导热层31之间出现缝隙或分层等情况出现,使得导热性能与力学性能降低,影响锅具的使用。
若干条所述下凹槽34和下凸条21设置为由导热层31圆心向导热层31圆边辐射状;使得因为下凸条21的导热系数高,呈放射状设置能够将热量从锅具外层20的中心和四周之间快速传导,使得高压锅底受热更均匀。
所述上凹槽33的槽顶的宽度小于槽底的宽度,所述上凸条11与锅具内层10连接一侧的宽度小于另一侧的宽度;所述下凹槽34的槽顶的宽度小于槽底的宽度,所述下凸条21与锅具外层20连接一侧的宽度小于另一侧的宽度。
使得在将锅具内层10、锅具外层20以及导热层31压制成复合金属板时,上凸条11和下凸条21容易变形,填充满上凹槽33和下凹槽34内;上凹槽33和下凹槽34的槽壁变形将上凸条11和下凸条21卡住,形成咬合结构,连接更紧密。
所述锅具内层10、锅具外层20以及导热层31通过热压钎焊连接,相邻的所述上凹槽33之间设置有若干个通孔;通孔用于通过钎料以及排气,使钎料能够到达每一个上凹槽33内,且排出锅具内层10和导热层31之间的气体,连接更紧密,导热性能以及力学性能更好。
实施例2
