Description

榨汁机
技术领域
本发明涉及厨房用具, 特别是涉及一种能从蔬菜、 水果榨取汁液或从豆类榨取豆浆的 榨汁机。 背景技术
现有榨汁机的榨汁方式主要有以下两种:
第一种是高速切削离心甩干榨汁。 这种榨汁方式是利用粉碎装置将待榨取汁液的蔬果 粉碎, 然后以高速旋转的方式利用离心力将汁液甩出。 此种榨汁方式具有的较大缺点是: 由于榨汁机高速运转过程中的噪音和振动均比较大, 对操作环境产生很大的噪音, 另外在 高速榨汁的过程中食品里的固有味道和营养也受到严重的破坏。
第二种是螺杆挤压式榨汁, 这种榨汁方式是利用螺杆结构挤压待榨取汁液的蔬果, 从 而将汁液分离出来。 此种榨汁方式虽然解决了噪音问题和使食品里的固有味道和营养不流 失, 但是却存在以下缺点: 首先, 此种榨汁方式主要利用螺杆和外壳内壁之间的旋转挤压 扭力将食物破碎和研磨, 因此所需力矩较大, 只能釆用大扭矩电机, 增加了榨汁机制造成 本; 而且, 外壳侧边集中承受的扭力过大, 长时间使用后外壳很容易裂开, 机器寿命短; 其次, 此种榨汁方式为了确保充分研磨, 榨汁头的长度不能太短, 导致外壳的高度较高, 一方面增加了产品制造成本, 另一方面不方便使用者操作; 再者, 此种榨汁方式很难将食 物中的纤维切断, 当遇到高纤维的食物时, 很容易把过滤网堵住, 导致出汁速度不够快。 发明内容

下面参考附图并结合实施例对本发明进行详细说明。 需要说明的是, 在不冲突的情况 下, 以下各实施例及实施例中的特征可以相互组合。
图 1及图 2所示为本发明其中一个实施例中的榨汁机的结构示意图, 榨汁机包括: 底 座 100、 驱动机构 200和榨汁部件 300, 其中, 底座 100的顶面 105具有用于安装榨汁部 件 300的支承面 110,在该支承面 110上设置有三个沿着圆周方向排布的卡扣 115。所示驱 动机构 200安装在所述底座 100内, 驱动机构 200的输出轴 210从支承面 110中部的通孔 伸出。
继续参见图 1及图 2, 所述榨汁部件 300主要由外壳 700、 可旋转地安装于所述外壳 700内的第一磨盘 500、与所述第一磨盘 500相对地安装在所述外壳 700内的第二磨盘 400 以及过滤装置 600组成, 其中, 所述外壳 700的顶部设置有开口部 710, 开口部 710的内 表面上设置有多个第二限位突起 740, 外壳 700底部设置有与所述底座 100上的卡扣 115 相配合的凹扣(图中未示出),所述外壳 700通过所述凹扣和所述卡扣 115可拆卸地安装在 所述支承面 110上。 所述外壳 700的内表面上设置有沿外壳 700的轴向方向延伸的多条引 导筋条 725和与引导筋条 725间隔设置的多条第三研磨筋条 730 , 优选地, 多条第三研磨 筋条 730的长短不一。
如图 3所示, 所述第一磨盘 500包括第一磨盘主体部 510和用于与所述驱动机构 200 的输出轴 210连接的驱动机构连接部 520, 所述驱动机构连接部 520上设置有与所述输出 轴 210相配合的多边形孔(图中未示出), 所述第一磨盘 500的驱动机构连接部 520可拆 卸地安装在所述输出轴 210上, 以方便清洗。 所述第一磨盘主体部 510具有第一磨面 511 , 在该第一磨面 511上设置有位于中部的圆柱体 518、 至少一条自所述圆柱体 518的外周侧 面延伸至第一磨盘主体部 510的外周侧面 516的第一研磨排料凸筋 512以及若干第一研磨 齿 513 , 所述圆柱体 518的顶面具有沿其轴向向外伸出的定位柱 515 , 该定位柱 515与第 二磨盘 400中部的定位孔 415配合, 起到定位作用。 所述第一研磨排料凸筋 512用于研磨 和排料, 所述第一研磨排料凸筋 512的顶面 512a高度大于或者等于所述第一研磨齿 513 的顶面 513a的最大高度。优选地, 所述第一研磨排料凸筋 512为弧形, 且所述第一研磨排 料凸筋 512的弯曲方向与工作时所述第一磨盘 500的旋转方向 (图 2中第一磨盘 500—侧 的箭头所指方向)相同。 所述第一研磨齿 513主要起到研磨作用。 优选地, 所述第一研磨 排料凸筋 512的数量为两条以上, 所有所述第一研磨排料凸筋 512在所述第一磨面 511中 心的周向上间隔排布, 并将所述第一磨面 511分成若干研磨区域, 每个研磨区域内均设置 有所述第一研磨齿 513。 优选地, 沿着工作时所述第一磨盘 500的旋转方向, 每个所述研 磨区域内的所述第一研磨齿 513顶面 513a的最大高度逐渐增大,这样实现分段研磨,一方 面有利于提高出汁率, 另一方面避免因食物体积过大导致卡机。 进一步地, 每个所述研磨 区域内的所有所述第一研磨齿 513的顶面 513a限定一个第一渐变面,所述第一渐变面的高 度从所述第一磨面 511的中部至边缘逐渐变小, 且所述第一渐变面与所述第一磨盘主体部 510的外周侧面 516的相交线的高度沿着工作时所述第一磨盘 500的旋转方向逐渐变小, 第一渐变面可以起到卸料作用, 避免压榨余渣集聚。 优选地, 所述第一研磨齿 513为自所 述第一研磨排料凸筋 512延伸至所述第一磨盘主体部 510的外周侧面 516的弧形, 且所述 第一研磨齿 513的弯曲方向与工作时所述第一磨盘 500的旋转方向相同, 相邻两条所述第 一研磨齿 513之间形成供汁液流出的第一排液槽 514, 方便排出研磨出的汁液。 第一磨盘 500上的第一研磨排料凸筋 512、 第一研磨齿 513与第二磨盘 400上的第二研磨排料凸筋 412和第二研磨齿 413配合形成第一研磨区域 A (见图 1 ), 第一研磨区域 A用于主要对食 物进行一次研磨和切断, 以提高出汁率, 和避免高纤维的食物没有切断而将过滤装置 600 的滤孔 615堵住。
进一步参见图 3, 所述第一磨盘主体部 510的外周侧面上设置有至少一条向外突出的 第一研磨筋条 517, 该第一研磨筋条 517与所述外壳 700内壁上的引导筋条 725配合形成 第二研磨区域 B (见图 1 ), 第二研磨区域 B用于对食物进行二次研磨, 以提高出汁率。
进一步参见图 3, 所述第一磨盘主体部 510的下部设置有用于安装过滤装置 600的台 阶状过滤装置安装部 530, 在所述过滤装置安装部 530 的表面设置有多个第一限位凹槽 535。
如图 4所示,所述第二磨盘 400包括第二磨盘主体部 410和供食物通过的食材通道 420, 所述第二磨盘主体部 410具有第二磨面 411 , 在该第二磨面 411上设置有位于中部的定位 孔 415、 与所述定位孔 415偏心设置的进料口 417、 一条自所述定位孔 415孔壁延伸至第 二磨盘主体部 410外周侧面 416的第二研磨排料凸筋 412以及第二研磨齿 413, 所述定位 孔 415与所述第一磨盘 500上的定位柱 515配合, 所述进料口 417与所述食材通道 420连 通, 用于进料。 所述第二研磨排料凸筋 412用于研磨和排料, 所述第二研磨排料凸筋 412 的顶面高度大于或者等于所述第二研磨排料凸筋 412的顶面的最大高度。 优选地, 所述第 二研磨齿 413为弧形, 且所述第二研磨齿 413的弯曲方向与工作时所述第一磨盘 500的旋 转方向相反, 这样第一研磨齿 513和第二研磨齿 413相互交错布置, 以防止卡料。优选地, 所有所述第二研磨齿 413的顶面限定一个第二渐变面, 所述第一渐变面的高度从所述进料 口 417至所述第二磨面 411的边缘逐渐增大, 这样, 第一磨面 511与第二磨面 411之间的 间距从进料口 417开始逐渐变小, 使食物先破碎再研磨, 避免因食物体积较大导致卡机。 优选地,所述第二研磨齿 413自所述第二研磨排料凸筋 412延伸至所述二磨盘的外周侧面, 相邻两条第二研磨齿 413之间形成供汁液流出的第二排液槽 414。
进一步参见图 4, 所述第二磨盘主体部 410的外周侧面 416上设置有多条向外凸出的 筋条 418 , 多个所述凸筋 418沿向圆心方向切除材料形成第二限位凹槽 419, 所述外壳 700 开口部 710的内侧面上形成有多个向内突出的与所述第二限位凹槽 419配合的第二限位突 起 740, 第二磨盘 400通过所述第二限位突起 740和所述第二限位凹槽 419可拆卸地安装 在所述外壳 700的开口部 710处, 由此可见, 本第二磨盘 400既起到研磨作用, 又起到盖 的作用。
所述第一磨盘 500和第二磨盘 400所用的材料为食品级塑胶材料或陶瓷或粉末冶金或 它们的组合。
图 7所示为本发明另一个实施例中的第二磨盘 400的结构示意图, 本实施例中的第二 磨盘 400与盖 900相互独立, 第二磨盘 400同样具有第二磨面和第二研磨齿, 所述盖 900 的外周侧面上设置有多条向外凸出的筋条 905 , 多个所述凸筋 905沿向圆心方向切除材料 形成第三限位凹槽 910, 该第三限位凹槽 910与所述外壳 700开口部 710的内侧面上的第 二限位突起 740配合, 所述盖通过所述第二限位突起 740和所述第三限位凹槽 910可拆卸 地安装在所述外壳 700的开口部 710处。 所述第二磨盘 400安装在所述盖 900内, 且在第 二磨盘 400与盖 900顶部之间设置有弹性元件 800。 这样, 第二磨盘 400与第一磨盘 500 之间的间距可根据食材体积的大小微调, 避免因食材体积太大导致卡机。
所示过滤装置 600用于分离蔬果汁和压榨余渣, 如图 5所示, 本实施例中的过滤装置 600 包括中空圆筒状过滤腔壁 610, 所述过滤腔壁 610上设置有若干滤孔 615 , 所述滤孔 615的孔径大小优选为由上往下逐渐减小。 优选地, 过滤腔壁 610的外表面上设置有一道 以上向外凸出的螺旋状第二研磨筋条 630, 该第二研磨筋条 630与所述外壳 700内壁上的 第三研磨筋条 730配合形成第三研磨区域 C (见图 1 ), 该第三研磨区域用于对食物进行三 次研磨, 以提高出汁率。
继续参见图 5 , 所述过滤装置 600还包括设置于所述过滤腔壁 610上端内表面上的多 条向内凸出的第一限位突起 620, 该第一限位突起 620与所述第一磨盘 500上的第一限位 凹槽配合, 所述过滤装置 600通过所述第一限位突起 620和第一限位凹槽可拆卸地安装在 所述第一磨盘 500上, 以方便清洗。
继续参见图 5 , 所述过滤装置 600还包括设置于过滤腔壁 610下端部上的多个推渣块 640和向下凸出的环状结构的挡渣筋条 660, 在所述挡渣筋条 660的向内方向设置有向下 凸出环状结构的能够防止内部的汁液混入残渣的挡汁筋条 670, 在所述挡汁筋条 670的内 壁上向下凸出形成有多条推汁块 650。 继续参见图 2, 所述外壳 700底部设置有挡渣凹槽 745和位于挡渣凹槽 745外侧的环状排渣平台 755 , 在该排渣平台 755顶面为倾斜面, 在 排渣平台 755顶面的端部处形成用于将残渣排出外壳 700的残渣出口 720, 且在排渣平台 755顶面上设置有间隔排列的多条第四研磨凸筋 760。 在所述挡渣凹槽 745 内侧形成有环 柱形结构的挡墙 765 , 在外壳 700的中心下端部分上形成有防水圆柱体 770, 防水圆柱体 770内部为供输出轴 210穿过的通孔 735 , 在所述防水圆柱体 770底部和所述挡墙 765底 部之间设有圆环面状的排汁平台 775 , 所述排汁平台 775的表面上形成有汁液排出倾斜表 面, 在汁液排出倾斜表面端部处形成有用于将汁液排出外壳 700的汁液出口 715 , 所述外 壳 700上所设的排渣平台 755上的第四研磨凸筋 760和所述推渣块 640的端面配合构成第 四研磨区域 D (见图 6 ), 第四研磨区域 D用于对食物进行四次研磨, 以提高出汁率。
根据本发明所述的榨汁机以如下方式工作和被使用。
当需要进行榨汁时, 打开榨汁机的操作开关, 将准备好的食品从所述第二磨盘 400所 设的食材通道 420中投入, 所述第一磨盘 500和过滤装置 600在驱动机构 200输出轴 210 的带动下运转, 食物从所述食材通道 420进入第一磨盘 500与第二磨盘 400之间并被逐渐 研磨, 食物的渣再进入第一研磨筋条 517与引导筋条 725之间不断被反复挤压研磨, 之后 进入第二研磨筋条 630与第三研磨筋条 730之间被不断反复挤压研磨,同时被过滤装置 600 过滤, 实现汁液和残渣分离, 最后残渣进入第四研磨区域 D再次被挤压研磨和过滤, 于是 在过滤装置 600的推渣块 640和推汁块 650的作用下残渣和汁液分别从残渣出口 720和汁 液出口 715流出到预先放置好的杯子。 榨汁完成后关掉电源即可完成榨汁工作。
由此可见, 本发明实施例中的榨汁机由于釆用了与现有技术完全不同的榨汁方式, 具 有以下有益效果:
1、 本实施例中的榨汁机的外壳承受的扭力小, 不容易裂开, 从而延长了机器使用寿 命;
2、 本实施例中的榨汁机的磨盘所需扭矩小, 因此可以釆用小扭矩电机, 降低机器制 造成本, 而且节能省电;
3、 本实施例中的榨汁机的第一磨盘和第二磨盘可以将食物破碎和研磨, 从而将食物 中的纤维切断, 可以避免因高纤维食物没有被切断而堵塞过滤装置滤孔的问题, 提高了出 汁速度;
4、 本实施例中的榨汁机的高度大大减低, 一方面可以减小产品体积, 节约制造和运 输成本, 另一方面方便使用者操作;
5、 本实施例中的榨汁机釆用四次研磨, 可显著提高出汁率。
6、 本实施例中的榨汁机的榨汁部件釆用可拆卸的装配方式, 装拆和清洗简单方便。 综上, 本发明的榨汁机具有成本低、 使用寿命长、 出汁速度快、 出汁率高且过滤装置 上的滤孔不容易被堵的显著优点, 此外, 电力消耗和噪音得到显著降低。
以上所述实施例仅表达了本发明的几种实施方式, 其描述较为具体和详细, 但并不能 因此而理解为对本发明专利范围的限制。应当指出的是,对于本领域的普通技术人员来说, 在不脱离本发明构思的前提下, 还可以做出若干变形和改进, 这些都属于本发明的保护范 围。
