Description

一种挤出式制冰机 技术领域
本实用新型涉及制冰机技术领域，尤其涉及一种挤出式制冰机。
背景技术
制冰机是一种将水通过蒸发器由制冷系统制冷剂冷却后生成冰的制冷机械设备，制冰机在制冰的过程中，需要将冰块进行破碎然后从制冰腔中挤出冰块，冰块不断挤出主要通过电机驱动螺杆来实现，通过螺杆的旋转将冰块不断的挤出，一般电机安装在螺杆的下端驱动螺杆转动，该结构容易使得螺杆内的水渗入电机，对防水要求较高，因此，有些制冰机将电机装在螺杆的上端，这样螺杆内的水就不会渗入电机中，不会有渗水的问题，但是螺杆在旋转中将冰块从下往上挤送的过程中，会受到冰块反向作用力，即反向挤推螺杆向下窜动，不仅容易滑脱，也会对电机造成一定的损伤，使得制冰机的使用寿命减短。
实用新型内容
针对上述现有技术的现状，本实用新型所要解决的技术问题在于提供一种防水性好，且能阻止螺杆向下窜动而延长制冰机使用寿命的挤出式制冰机。

进一步的，所述电机内在输出轴上套设有角接触轴承。
进一步的，所述筒体的下方设有用于注水的进水口。
进一步的，所述筒体的底部设有密封件。
进一步的，所述筒体的顶部设有口模，该口模上设有若干个连通口，该筒体的上方设有出冰口，该连通口连通筒体和出冰口。
进一步的，所述电机的输出轴插入所述螺杆的上端，所述固定销径向穿连输出轴和螺杆。
进一步的，所述电机为无刷电机。
与现有技术相比，本实用新型的优点在于：本实用新型通过固定销连接电机的输出轴和螺杆，使得螺杆与输出轴固定连接，有效防止螺杆上下窜动，可以抵抗冰块的反作用力，使得螺杆的转动更加稳定，不易滑脱形成故障，不易损坏，且电机安装在筒体的上方，不会发生渗水问题，延长使用寿命。

具体实施方式
下面结合具体实施方式对本实用新型作进一步说明。
在本实用新型的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“顺时针”、“逆时针”、“轴向”、“径向”、“周向”等指示的方位或位置关系，仅是为了便于描述本实用新型和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本实用新型的限制。
此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。在本实用新型的描述中，“多个”的含义是至少两个，例如两个，三个等，除非另有明确具体的限定。
在本实用新型中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系，除非另有明确的限定。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本实用新型中的具体含义。
在本实用新型中，除非另有明确的规定和限定，第一特征在第二特征“上”或“下”可以是第一和第二特征直接接触，或第一和第二特征通过中间媒介间接接触。而且，第一特征在第二特征“之上”、“上方”和“上面”可是第一特征在第二特征正上方或斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”可以是第一特征在第二特征正下方或斜下方，或仅仅表示第一特征水平高度小于第二特征。
如图1-4所示，本实用新型提供一种挤出式制冰机，包括安装架1，该安装架1的底部设有压缩机2，该安装架1的背面设有冷凝器3，该安装架1上在所述压缩机2的上方设有筒体5，该筒体5内设有螺杆6，螺杆6用于将冰块从下往上推送，该筒体5外缠绕有蒸发器4，该安装架1顶部设有电机7，该电机7的输出轴7.1与所述螺杆6的上端传动连接，且该螺杆6的上端通过固定销8与电机7的输出轴7.1固定连接，所述压缩机2的出口连接冷凝器3的进口，所述冷凝器3的出口连接蒸发器4的进口，所述蒸发器4的出口连接压缩机2的进口，制冷剂在压缩机2、冷凝器3、蒸发器4三者之间循环流动，蒸发器4带走筒体5内的热量，将筒体5内的水凝结成冰，通过螺杆6转动向上挤出冰块。
本实用新型通过固定销8连接电机7的输出轴7.1和螺杆6，使得螺杆6与输出轴7.1固定连接，有效防止螺杆6上下窜动，可以抵抗冰块的反作用力，使得螺杆6的转动更加稳定，不易滑脱形成故障，不易损坏，且电机7安装在筒体5的上方，不会发生渗水问题，延长使用寿命。
其中，所述电机7内在输出轴7.1上套设有角接触轴承7.2，由于螺杆6通过固定销8与电机7的输出轴7.1固定连接，螺杆6在转动过程中由下向上挤推冰块，会受到冰块向下的反向作用力，使得输出轴7.1也受到向下的拉力，而角接触轴承7.2的设置可以分担输出轴7.1受到的拉力，能更好的保护输出轴7.1。
其中，所述筒体5的下方设有用于注水的进水口5.1。
其中，所述筒体5的底部设有密封件9，防止筒体5内的水渗出，起到防水效果。
其中，所述筒体5的顶部设有口模10，该口模10上设有若干个连通口10.1，该筒体5的上方设有出冰口11，该连通口10.1连通筒体5和出冰口11，该若干个连通口10.1能够加快冰块推出，减少冰块堆积堵塞，提升出冰效率。
其中，所述电机7的输出轴7.1插入所述螺杆6的上端，所述固定销8径向穿连输出轴7.1和螺杆6，由于电机7设置在上方，电机 7的输出轴7.1与螺杆6的上端的连接处被出冰口11包裹，该输出轴7.1插入螺杆6上端的结构设置，可以进一步起到隔离防水的作用，螺杆6阻隔电机7的输出轴7.1直接暴露在出冰口11内，避免出冰口11内的湿气进入电机7，提高密封防水性。
其中，所述电机7采用无刷电机，无刷电机噪音低，运转顺畅，满足用户降噪的需求，且使用寿命长，维护成本低。
使用时，压缩机2通过活塞压缩制冷剂，制冷剂由气态变成液态放热，液态的制冷剂进入冷凝器3进行散热后通过毛细管进入蒸发器4，制冷剂进入蒸发器4后由液态变为气态吸热，蒸发器4缠绕于筒体5外部，随着制冷剂由液态变为气态可以带走筒体5的热量，使得筒体5内温度下降，使得筒体5内的水变成冰，通过筒体5内螺杆6的转动将冰块由下向上挤出，冰块通过口模10从出冰口11输出，在螺杆6挤推冰块的过程中，螺杆6也会受到冰块反向作用力，该反向作用力向下推螺杆6，螺杆6上端通过固定销8连接电机7的输出轴7.1，可以有效防止螺杆6脱离，防止螺杆6向下窜动，可以抵抗冰块的反作用力，使得螺杆6的转动更加稳定，再者，电机7内在输出轴7.1上套设有角接触轴承7.2，可以分担输出轴7.1受到螺杆6传递的力，能更好的保护输出轴7.1，不易损坏，且电机7安装在筒体5的上方，不会发生渗水问题，延长使用寿命。
本实用新型实施例涉及到的材料、试剂和实验设备，如无特别说明，均为符合制冰机领域的市售产品。
最后应说明的是：以上实施例仅用以说明本实用新型的技术方案，而非对其限制；尽管参照前述实施例对本实用新型进行了详细的说明，本领域的技术人员应当理解，其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行同等替换；而这些修改或者替换，并不使相应技术方案的本质脱离本实用新型各实施例技术方案的精神与范围。
