Description

一种减速器传动的新型冰淇淋机 技术领域
本发明涉及冷冻食品加工设备领域，特别是涉及一种减速器传动的新型冰淇淋机。
背景技术
现有的软冰淇淋机一般结构较复杂，其搅拌装置与搅拌电机通过皮带轮式传动装置远距离相连，在机箱内呈上下布置，体形较大，需要占据较大的空间，并且重量较重。由于采用了大功率的电机和压缩机，虽然处理能力较大，但耗电较高，价格较贵，很大程度上增大了生产成本，不适合对处理能力要求不高的商业性营业门市以及家庭使用。
其次，传统的皮带轮传动方式需要配备功率较大的电机，功耗较大，并且在运行过程中容易出现打滑摆动，噪音较大，存在运行不稳定以及较大的噪声污染等缺陷。
再者，目前市场上出售的冰淇淋机中，出料阀的回弹复位机构一般设于冰淇淋机前面板的内部，受加工或装配误差等因素影响，回弹顶杆底部与阀塞顶部之间的间隙并不一致，需要现场选用不同长度的阀塞多次配对，后续维修时需要将冰淇淋机前面板打开，才能维修和更换回弹复位零配件，不仅安装和维护不便，费时费力，而且回弹复位精度存在较大误差，容易出现回位不准的现象。
另外，在现有技术的冰淇淋机中，搅拌装置包括空心连续螺旋结构及断螺旋结构，空心连续螺旋结构的搅拌装置在使用时，使冰淇淋浆料回流循环充分，但其存在搅拌不充分及推力小，不利于挤压成型，进而影响冰淇淋机工作效率的弊端，而断螺旋结构的搅拌装置在工作中的工作推力大能满足冰淇淋机的效率要求，但由于该搅拌装置外周和搅拌缸缸体内壁之间通常是较为紧密的间隙配合，因此在搅拌装置旋转搅拌并输送冰淇淋浆料的过程中，将不可避免的在搅拌缸缸壁上残留一层冰淇淋浆料，该部分残留的浆料被冻硬后容易产生冻缸的现象，进而逐渐影 响冰淇淋机的制冷效率和冰淇淋的口感。
当前冰淇淋机大多采用内外螺旋式蒸发器，即采用双层筒状结构，内套筒与外套筒之间设置螺旋槽或螺旋件，虽然此种结构相比前绕管式或翅片式蒸发器，热交换面积有所增大，制冷效率有所提高，但因螺旋件一般采用实心圆形弹簧，弹簧的表面与内套筒的外壁接触面积较小，通过弹簧的气液态制冷剂与内套筒内的浆料接触面积也有限，存在通过改进螺旋件的结构进一步增大热交换面积以提高制冷效率的空间。
发明内容
本发明主要解决的技术问题是提供一种体积较小、重量较轻、成本较低、刮料效果好、推力大、制冷效率高及采用非皮带轮传动的新型冰淇淋机。另外，该新型冰淇淋机还设有安装维护简便、回弹复位准确的出料阀自动回弹复位机构。
为解决上述技术问题，本发明采用的一个技术方案是：提供一种减速器传动的新型冰淇淋机，包括机壳，所述机壳上设有压缩机、冷凝器、蒸发器、搅拌缸、搅拌轴、电机、进料盆、出料阀及控制面板；所述机壳是由前面板、后面板、顶面板、底面板、左面板及右面板依次相连的长方形箱体，所述压缩机及所述冷凝器设于所述底面板上，所述压缩机与所述冷凝器、所述蒸发器依次相连；所述搅拌缸设于所述前面板上，所述蒸发器缠绕于所述搅拌缸的外壁；所述搅拌轴设于所述搅拌缸内，并与所述电机相连且处于同一水平面上；所述进料盆设于所述顶面板上，并与所述搅拌缸连通；所述出料阀设于所述前面板上，并与所述搅拌缸连通；所述控制面板设于所述前面板上，并分别与所述压缩机、所述冷凝器及所述电机电连接。
本发明的有益效果是：
1、区别于现有技术的情况，本发明的新型冰淇淋机将搅拌电机与搅拌缸在同一水平面近距离设置，采用减速器作为搅拌电机与搅拌轴的传动装置，不仅大大减小了设备体积，节省了设备的生产空间，而且由于采用了小功率的压缩机和搅拌电机，既有利于降低生产成本，又进一 步减小了设备体积，降低了整台机器的耗能，具有较佳的能效比。本发明具有结构简单、体积小巧、重量较轻、操作简便、成本较低、节能省电以及自动化程度高等特点，经济效益较好，无机械传动噪声，工作性能稳定，符合节能环保要求，特别适合于商业性营业门市以及家庭使用。
2、本发明的新型冰淇淋机将断螺旋形搅拌装置结构和刮刀组件巧妙结合成一体，克服了现有技术中断螺旋形搅拌装置的缺陷，使得冰淇淋浆料的搅拌输送与刮取分两部分独立完成，断螺旋形搅拌装置负责浆料的搅拌和输送，因其搅拌效果好、推力大且易挤压成型的特点，该刮刀能根据搅拌装置与搅拌缸缸壁的间隙灵活调节刮刀的位置以使其紧贴缸体内壁，将缸体内壁的冰淇淋浆料全部刮取下来，避免了搅拌装置与缸体内壁由于存在间隙引起的一系列问题，并改善了热交换速度、有效提高了冰淇淋机的制冷效率。
3、本发明的新型冰淇淋机通过在阀体的顶部设置压板，在出料阀的阀塞上安装高强度弹簧，弹簧两端分别与阀塞及压板相抵，用户向下拉动操控手柄对阀塞施加作用力，阀塞向上运动打开阀口，同时弹簧受力压缩；取料完毕后，用户松开操控手柄，阀塞在弹簧的弹性回复力作用下向下运动复位，从而关闭阀口。本发明设有自回弹功能的出料阀，无需用户手动驱动阀塞关闭阀口，安装及维修时无需打开冰淇淋机外壳，仅需将阀体取下来，即可方便的取下各零部件进行维护或更换，具有结构简单、安装维护方便、回位准确及美观大方等特点，有效提高了用户的操作效率。
4、本发明的蒸发器将螺旋件有规则地绕制于内缸体的外壁上并经焊接固定，再将外缸体套接于螺旋件及内缸体上，由于螺旋件的特殊结构，制冷剂与内缸体中的浆料的接触面积及时间大大增加，即增加了热交换面积，从而使得蒸发器的热交换效率提高，制冷系统的制冷速度和效果大大提升。

如图6及图7所示，在本发明中，搅拌轴6包括传动轴601、分别设置在传动轴601表面的搅拌叶片602及刮刀组件603，搅拌叶片602包括沿传动轴601轴向排列的第一片状叶片组602a、第二片状叶片组602b及设置在传动轴601末端的螺旋叶片602c，第一片状叶片组602a与第二片状叶片组602b分别对称设置在传动轴601的两侧表面，螺旋叶片602c的一端与相邻的第二片状叶片组602b连为一体；刮刀组件603包括沿传动轴601轴向排列的第一刮刀组件60301及第二刮刀组件 60302，第一刮刀组件60301、第二刮刀组件60302分别对称设于第一片状叶片组602a与第二片状叶片组602b之间。第一刮刀组件60301包括第一支撑座60301a及安装于第一支撑座60301a上的第一刮刀60301b，第二刮刀组件60302包括第二支撑座60302a及安装于第二支撑座60302a上的第二刮刀60302b。
如图8及图9所示，第一支撑座60301a包括第一连接件60301a1及第一卡勾件60301a2，第一连接件60301a1的一端固定于传动轴601的外表面，另一端与第一卡勾件60301a2呈一体成型结构。第一卡勾件60301a2包括第一水平部60301a21和第一勾形部60301a22，第一水平部60301a21与第一勾形部60301a22呈一体成型结构，第一水平部60301a21与第一连接件60301a1相连。第一连接件60301a1沿传动轴601水平径向的长度大于第一勾形部60301a22沿传动轴601径向水平方向的长度，第一连接件60301a1的与第一勾形部60301a22相对的端面上固定有第一销轴60301a3，第一刮刀60301b上设有第一通孔60301b1，并通过第一通孔60301b1与第一销轴60301a3连接，第一刮刀60301b在第一连接件60301a1、第一水平部60301a21及第一勾形部60301a22限定的范围内以第一销轴60301a3为中心转动。
如图10及图11所示，第二支撑座60302a包括第二连接件60302a1及第二卡勾件60302a2，第二连接件60302a1的一端固定于传动轴601的外表面，另一端与第二卡勾件60302a2呈一体成型结构。第二卡勾件60302a2包括第二水平部60302a21和第二勾形部60302a22，第二水平部60302a21与第二勾形部60302a22呈一体成型结构，第二水平部60302a21与第二连接件60302a1相连。第二连接件60302a1沿传动轴601水平径向的长度大于第二勾形部60302a22沿传动轴601径向水平方向的长度，第二连接件60302a1的与第二勾形部60302a22相对的端面上固定有第二销轴60302a3，第二刮刀60302b上设有第二通孔60302b1，并通过第二通孔60302b1与第二销轴60302a3连接，第二刮刀60302b在第二连接件60302a1、第二水平部60302a21及第二勾形部60302a22限定的范围内以第二销轴60302a3为中心转动。
请一并参阅图6、图7、图8及图9，以第一刮刀组件60301为例说明刮刀组件603的结构及工作过程。由于第一支撑座60301a具备一定的宽度，因此第一刮刀60301b的刀背能被限定在第一连接件60301a1及第一卡勾件60301a2之间，加上第一销轴60301a3的作用，限制了第一刮刀60301b往前后方向的移动，上下方向的晃动及水平方向的转动。当搅拌轴6在搅拌缸5内工作时，第一刮刀60301b根据搅拌轴6与搅拌缸5缸壁的间隙来调节并固定第一刮刀60301b的转动角度，以使第一刮刀60301b的刀刃紧贴缸体内壁，这样使得冰淇淋浆料的搅拌输送与刮取分两部分独立完成，断螺旋形搅拌装置负责浆料的搅拌和输送：冰淇淋浆料在被搅拌输送的过程中，在第一片状叶片组602a、第二片状叶片组602b及螺旋叶片602c旋转作用下能获得更大的推力、且搅拌、导热地更均匀、有效减少了搅拌时间并使浆料保持原有组织结构，让冰淇淋颗粒冰晶结构保持在一定合理范围内、提高膨化率，增加了冰淇淋的质地与口感，并满足了对冰淇淋机高工作效率的要求；而第一刮刀组件60301负责搅拌缸内壁的浆料刮取：在搅拌装置中，搅拌轴6的轴心线、搅拌叶片602的轴心线与搅拌缸5缸体的中心线为同一线，从而搅拌轴6旋转时，第一刮刀组件60301将在阻力和离心力作用下，受第一连接件60301a1、第一水平部60301a21、第一勾形部60301a22及第一销轴60301a3的限制，并根据搅拌轴6与搅拌缸5缸壁的间隙固定第一刮刀60301b的转动角度，以使第一刮刀60301b的刀刃能绕其旋转轴心线紧贴缸体内壁，避免了第一刮刀60301b与搅拌缸5内壁产生间隙并且能将缸体内壁的冰淇淋浆料全部刮下来，改善了热交换速度并有效提高了冰淇淋机的制冷效率，也有助于改善冰淇淋的冰晶组织结构，提高了其口感。同时，由第一刮刀60301b与缸体内壁接触进行刮料，避免了搅拌叶片602在搅拌中直接接触缸体内壁产生磨损，因此有效地提高了搅拌叶片602的使用寿命。
请继续参阅图4所示，在本实施例中，冷凝器4包括冷凝管401和冷凝风机402，冷凝风机402与冷凝管401固定连接成一体；冷凝管401的一端与压缩机3相连，另一端与蒸发器12相连。蒸发器12螺旋缠绕 于搅拌缸5的外壁；搅拌缸5设于前面板101上，搅拌轴设于搅拌缸5内，并与电机8相连；进料盆9设于顶面板103上，并与搅拌缸5连通。
请参考图4，在本发明中，进料盆9包括盆体901及下料管902，盆体901与下料管902为一体成型，下料管902的下端与搅拌缸5连通。本发明减速器传动的新型冰淇淋机进一步包括膨化管13，膨化管13设于下料管902内，用于对进料盆9内的浆料进行膨化。
如图14及图15所示，搅拌缸5包括内缸体501及外缸体502，蒸发器12包括螺旋件1201及封闭件1202，螺旋件1201有规则地绕制于内缸体501的外壁上，外缸体502套接于螺旋件1201及内缸体501上，其两端通过封闭件1202密封；内缸体501与下料管902相连通，外缸体502的两端设有工质进口502a及工质出口502b；其中，螺旋件1201的横截面为矩形，螺旋件1201的内表面与1201a内缸体501的外壁紧密焊固；螺旋件1201的侧面设有间隔分布的凹凸面1201b。特别地，凹凸面1201b的纵截面形状包括方形、矩形、梯形或波浪形的一种或多种。
当蒸发器12进行工作时，冰淇淋浆料从下料管902进入内缸体501中，制冷剂从工质进口502a进入蒸发器12，并在内缸体501、外缸体502及螺旋件1201之间形成的制冷剂通道内流动，与内缸体501中的浆料进行热交换，制冷剂蒸发吸热后从工质出口502b处流出，进入下一个制冷循环。由于螺旋件1201的横截面为矩形，螺旋件1201的内表面1201a与内缸体501的外壁紧密接触，与现有普遍采用的圆柱体绕制而成的螺旋弹簧(其横截面为圆形，与内缸体的接触面仅为螺旋弹簧圆柱面的一部分)相比，本发明相对增大了螺旋件1201与内缸体501之间的接触面积，当制冷剂在内缸体501与外缸体502之间流动时能通过螺旋件1201的内表面1201a传热，与内缸体501充分进行热交换，制冷剂与内缸体501之间进行热交换的有效接触面积明显增大，相应缩短了制冷时间，有效提高了制冷效率。同时，螺旋件1201的侧面为间隔分布的凹凸面1201b，螺旋件1201的比表面积大大增加，制冷剂通过螺旋件1201的行程也相应增加，延长了同等体积下的制冷剂与内缸体501之间的热交换时间，增大了单位时间内的有效制冷量，从而大大提升了蒸发 器12的制冷效率。
请参考图3，在本发明中，出料阀10设于前面板101上，并与搅拌缸5连通；出料阀10为塑胶材质，出料阀10的外缘环绕有LED灯14，通电状态下常亮，起美观装饰效果。
请继续参考图1、图2及图12，出料阀10包括阀体1001、安装板1002、阀塞1003、压板1004、操控手柄1005、横轴1006、防护套(图中未画出)、第一紧固螺钉1007及第二紧固螺钉1008，阀体1001包括前端部1001a及后端部1001b，前端部1001a分别设有阀塞安装孔(图中未画出)及手柄安装孔(图中未画出)，阀塞安装孔贯穿于前端部1001a，手柄安装孔与阀塞安装孔相贯通；安装板1002包括第一安装板1002a及第二安装板1002b，第一安装板1002a及第二安装板1002b对称分布于前端部1001a的两侧，且均与后端部1001b相固定；第一安装板1002a及第二安装板1002b的同一端分别设有第一通孔1002a1及第二通孔1002b1。
请看图13，阀塞1003设于阀塞安装孔内，阀塞1003为上粗下细的圆柱体，包括上段1003a、中段1003b及下段1003c，中段1003b及下段1003c的直径大于上段1003a，中段1003b上设有方孔1003b1：压板1004固定于后端部1001b上，压板1004设有圆孔1004a，圆孔1004a与阀塞安装孔相对应；操控手柄1005设于手柄安装孔内，其一端嵌于方孔1003b1内，操控手柄1005上设有轴孔(图中未画出)；横轴1006依次穿过第一通孔1002a1、轴孔及第二通孔1002a2；其中，上段1003a穿设于圆孔，上段1003a套设有弹性件1009，弹性件1009的一端与中段1003b的上表面相抵，另一端与压板1004的下表面相抵。
如图13所示，压板1004设有第二圆孔1004b及第三圆孔1004c，前端部1001a设有第一螺孔1001a1及第二螺孔1001a2，第一紧固螺钉1007穿过第二圆孔1004b并与第一螺孔1001a1相配合，第二紧固螺钉1008穿过第三圆孔1004c并与第二螺孔1001a2相配合，从而将压板1004与前端部1001a相固定。防护套为塑料材质，设于压板1004及前端部1001a之间，并套设于弹性件1009、第一固定螺钉1007及第二紧固螺钉 1008上，具有美观防尘功用。
当用户向下扳动操控手柄1005时，操控手柄1005嵌入阀塞1003的方孔1003b1内的一端翘起，带动阀塞1003竖直向上运动，从而打开阀体1001的阀口(图中未画出)进行打糕出料，同时弹性件1009的两端受压板1004及中段1003b的挤压而压缩；当浆料出料完成之后，用户松开操控手柄1005，阀塞1003在弹性件1009的弹性回复力作用下竖直向下移动，从而关闭阀体1001的阀口结束打糕。
请继续参考图3，控制面板11设于前面板101上，并分别与压缩机3、冷凝器4及电机8电连接。控制面板11设于前面板101的上部，控制面板11上设有数码管显示屏1101、清洗键1102、停止键1103、自动键1104、手动键1105及工作状态指示灯1106，用于控制减速器传动的新型冰淇淋机的运行。
如图1所示，本发明减速器传动的新型冰淇淋机进一步包括接料槽15，接料槽15设于前面板101的底部，并位于出料阀10的正下方，用于收集从出料阀10下散落的余料。
本发明的具体工作过程如下：
首先将机器接电，前面板101上的LED灯14闪烁常亮，此时打开机盖2，放入清水进搅拌缸5，按清洗键1102对搅拌缸5中存留的浆料进行清洗，清理完毕后按停止键，将软冰淇淋粉放入进料盆9中，软冰淇淋粉通过膨化管13混入空气后再通过下料管902落入搅拌缸5中；接着启动自动键1104，此时压缩机3、冷凝器4及电机8均开始工作，搅拌缸5内的冰淇淋浆料不断冷却成形；当数码管显示屏1101显示的电流值达到一定值时，搅拌时间到达控制面板11内置的控制程序的预设值，压缩机3及冷凝器4自动停止工作，再通过操作出料阀10上的操控手柄1005，在搅拌缸5内的搅拌轴的配合下将搅拌缸5内成形的软冰淇淋从出料阀10中挤出搅拌缸5，从而得到制作好的软冰淇淋。当需要继续制冷或倒入浆料进行下一次打糕时，启动手动键1105，压缩机3、冷凝器4、电机8及蒸发器12重新开始工作，进入下一轮制糕循环。
在本发明中，搅拌缸、蒸发器、搅拌轴、减速器、进料盆及出料阀 的数量为一个、两个或两个以上，在此不作限定，且本发明新型冰淇淋机的尺寸及规格不限于上述所限定的内容。本发明减速器传动的新型冰淇淋机既可为单缸小型冰淇淋机也可为多缸大型冰淇淋机，既可为软冰淇淋机也可为硬冰淇淋机，供于商业性营业门市或家庭使用。
另外，本发明的传动机构、出料阀机构及蒸发器结构也可用于冰沙机、雪泥机及果汁机等其他相关冷冻设备，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，均同理包括在本发明的专利保护范围内。
本发明减速器传动的新型冰淇淋机的搅拌电机与搅拌缸在同一水平面近距离设置，采用减速器作为搅拌电机与搅拌轴的传动装置，不仅大大减小了设备体积，节省了设备的生产空间，而且由于采用了小功率的压缩机和搅拌电机，既有利于降低生产成本，又进一步减小了设备体积，降低了整台机器的耗能，具有较佳的能效比。本发明具有结构简单、体积小巧、重量较轻、操作简便、成本较低、节能省电以及自动化程度高等特点，经济效益较好，无机械传动噪声，工作性能稳定，符合节能环保要求，特别适合于商业性营业门市以及家庭使用。另外，本发明将断螺旋形搅拌装置结构和刮刀组件巧妙结合成一体，克服了现有技术中断螺旋形搅拌装置的缺陷，使得冰淇淋浆料的搅拌输送与刮取分两部分独立完成，断螺旋形搅拌装置负责浆料的搅拌和输送，因其搅拌效果好、推力大且易挤压成型的特点，该刮刀能根据搅拌装置与搅拌缸缸壁的间隙灵活调节刮刀的位置以使其紧贴缸体内壁，将缸体内壁的冰淇淋浆料全部刮取下来，避免了搅拌装置与缸体内壁由于存在间隙引起的一系列问题，并改善了热交换速度、有效提高了冰淇淋机的制冷效率。本发明的新型冰淇淋机通过在阀体的顶部设置压板，在出料阀的阀塞上安装高强度弹簧，弹簧两端分别与阀塞及压板相抵，用户向下拉动操控手柄对阀塞施加作用力，阀塞向上运动打开阀口，同时弹簧受力压缩；取料完毕后，用户松开操控手柄，阀塞在弹簧的弹性回复力作用下向下运动复位，从而关闭阀口。本发明设有自回弹功能的出料阀，无需用户手动驱动阀塞关闭阀口，安装及维修时无需打开冰淇淋机外壳，仅需将阀体取 下来，即可方便的取下各零部件进行维护或更换，具有结构简单、安装维护方便、回位准确及美观大方等特点，有效提高了用户的操作效率。另外，本发明的蒸发器将螺旋件有规则地绕制于内缸体的外壁上并经焊接固定，再将外缸体套接于螺旋件及内缸体上，由于螺旋件的特殊结构，制冷剂与内缸体中的浆料的接触面积及时间大大增加，即增加了热交换面积，从而使得蒸发器的热交换效率提高，制冷系统的制冷速度和效果大大提升。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
