Description

热水机 技术领域
本发明属于饮用水设备技术领域， 具体地说， 是涉及一种热水机。
背景技术
热水机是家庭中的常用小家电， 为用户提供热水， 满足用户对热水的使用 需求。 目前， 热水机主要有两种： 即热式热水机和传统电水壶。
即热式热水机能够即时加热少量冷水， 使用户能够立即获得少量热水， 满 足人数较少时对少量热水的需求； 在人数较多需要大量热水时， 要想即时获得 大量的热水， 就需要用户在热水机旁边一杯一杯的盛接热水， 需要等待较长的 时间， 而且当接完最后一杯水的时候， 第一杯水的温度可能已经远低于用户期 望的温度， 对用户来讲非常不方便。 因此， 即热式热水机适用于人数较少时， 不适用于多人需要大量热水的情况。
传统电水壶是在加热完整壶水后再提供给用户， 满足较多人同时对热水的 需求， 但当人数较少、 需要的热水量不大时， 加热完的整壶水用不尽， 造成资 源浪费。
如果在家庭中既备有即热式热水机也备有传统电水壶， 需要根据用水人数 及用水量的不同来选取即热式热水机或传统电水壶， 使用不便， 而且占用较大 的储物空间。
发明内容
本发明提供了一种热水机， 既能实现即热式热水机的功能， 也能实现传统 电水壶的功能， 结构简单， 使用方便， 且节省了储物空间。
为了解决上述技术问题， 本发明采用以下技术方案予以实现：
一种热水机， 包括壶体和位于壶体外部的加热管， 在壶体上至少形成有第 一开口和第二开口， 在第一开口和加热管的进水口之间连接有供水管， 在加热 管的出水口处连接有连接管， 在所述连接管上形成有第三开口和第四开口， 第 四开口的位置低于第三开口的位置，在第三开口和第二开口之间连接有回水管， 第四开口通过二通阀连接即时出水口； 在供水管上设置有水泵。
进一歩的， 所述供水管从所述第一开口处伸入到所述壶体底部。
又进一歩的， 所述供水管包括第一供水管和第二供水管， 第一供水管位于 所述壶体内部且与所述第一开口连接， 第二供水管位于壶体外部且与第一开口 连接， 第一供水管和第二供水管在第一开口处对接。
更进一歩的， 所述第一开口和所述第二开口均位于所述壶体顶部。
优选的， 所述加热管竖直放置， 且加热管的进水口位于其底部， 加热管的 出水口位于其顶部。
进一歩的， 所述加热管为玻璃加热管。
本发明还提出了一种热水机， 包括壶体和位于壶体外部的加热管， 在壶体 上至少形成有第一开口和第二开口， 在第一开口和加热管的进水口之间连接有 供水管， 加热管的出水口通过连接管连接三通阀的进水口， 三通阀的一个出水 口通过回水管连接第二开口， 三通阀的另一个出水口连接即时出水口； 在供水 管上设置有水泵。
进一歩的， 所述供水管从所述第一开口处伸入到所述壶体底部。
又进一歩的， 所述供水管包括第一供水管和第二供水管， 第一供水管位于 所述壶体内部且与所述第一开口连接， 第二供水管位于壶体外部且与第一开口 连接， 第一供水管和第二供水管在第一开口处对接。
更进一歩的， 所述第一开口和所述第二开口均位于所述壶体顶部； 所述加 热管竖直放置， 且加热管的进水口位于其底部， 加热管的出水口位于其顶部； 加热管为玻璃加热管。
与现有技术相比， 本发明的优点和积极效果是： 本发明的热水机既能即时 加热少量水供用户使用， 实现即热式热水机的功能， 也可以加热完壶体内的整 壶水后再供用户使用， 实现传统电水壶的功能。 热水机将即热式热水机和传统 电水壶的功能二合一， 既满足了较少人对少量热水的即时需求， 也满足了较多 人对大量热水的需求， 且结构简单、 使用方便， 为用户节省了储物空间。
结合附图阅读本发明实施方式的详细描述后， 本发明的其他特点和优点将 变得更加清楚。
附图说明：
图 1是本发明所提出的热水机的一个实施例的工作原理图；
图 2是基于图 1工作原理的热水机的一个实施例的结构示意图；
图 3是本发明所提出的热水机的另一个实施例的工作原理图。
具体实施方式：
下面结合附图对本发明的具体实施方式作进一歩详细地说明。
实施例一、 本实施例的热水机主要由壶体 1、 加热管 4、 即时出水口 6和 用于控制加热管 4的出水口处的水的流向的分流部组成， 当需要加热管 4的出 水口处的水流入壶体 1时， 分流部控制加热管 4的出水口处的水流向壶体 1， 当需要加热管 4的出水口处的水从即时出水口 6流出时， 分流部控制加热管 4 的出水口处的水流向即时出水口 6;在本实施例中，分流部可以选择为二通阀 8， 参见图 1所示。 具体来说， 在壶体 1上至少形成有两个开口： 第一开口和第二 开口， 在第一开口和加热管 4的进水口之间连接有供水管， 在加热管 4的出水 口处连接有连接管 7， 在连接管 7上形成有两个开口： 第三开口和第四开口， 且第四开口的位置比第三开口的位置低， 在第三开口和第二开口之间连接有回 水管 5，第四开口通过二通阀 8与即时出水口 6连接。在供水管上设置有水泵 3， 用于将壶体 1内的水抽出。
二通阀 8控制加热管 4的出水口处的水的流向， 控制原理如下：
第三开口与回水管 5保持连通状态， 第四开口与即时出水口 6的连通与否 由二通阀 8控制； 当关闭二通阀 8时， 第四开口与即时出水口 6不连通， 加热 管 4的出水口处的水通过第三开口流入回水管 5; 当打开二通阀 8时， 第四开 口与即时出水口 6连通， 由于第四开口的位置比第三开口的位置低， 因此加热 管 4的出水口处的水通过第四开口流向即时出水口 6。 当用户需要大量热水时， 即需要加热壶体 1内的整壶水时， 关闭二通阀 8， 加热管 4的出水口处的水通过连接管 7流入回水管 5， 并通过第二开口流入壶 体 1， 依次循环， 直至壶体 1内水达到预定温度； 当用户即时需要少量热水时， 打开二通阀 8，加热管 4的出水口处的水通过连接管 7流向即时出水口 6，并通 过即时出水口 6流出， 满足用户对少量热水的需求。
作为本实施例的一种优选设计方案， 所述供水管从第一开口处伸入到壶体 1的底部， 所述供水管分为两部分： 第一供水管 2-1和第二供水管 2-2， 第一供 水管 2-1位于壶体 1的内部且与第一开口连接， 第二供水管 2-2位于壶体 1的 外部且与第一开口连接，第一供水管 2-1和第二供水管 2-2在第一开口处对接。 水泵 3设置在第二供水管 2-2上， 将壶体 1内的水抽入到供水管， 并导入到加 热管 4中，经过加热管 4加热后，热水从加热管 4的出水口流入到连接管 7中， 并经由二通阀 8控制流向回水管 5或流向即时出水口 6。
所述加热管 4优选为竖直放置，加热管 4的进水口设置在加热管 4的底部， 加热管 4的出水口设置在加热管 4的顶部，供水管将水引入加热管 4的进水口， 并通过加热管 4的进水口进入加热管 4， 水在加热管 4内向上流动， 逐渐充满 整个加热管 4，最后经加热管 4的出水口流入连接管 7。由于加热管 4竖直放置， 从其底部进水口进入加热管 4的水， 会逐渐充满整个加热管 4， 防止加热管 4 局部干烧， 缩短其使用寿命。
第一开口和第二开口都设置在壶体 1的顶部， 壶体 1的底部无开口， 在壶 体 1内的水加热结束后， 可以将壶体 1单独取下， 热水通过第二开口倒出， 不 用担心壶体 1的底部漏水。 当然， 在所述壶体 1上还可以再形成一个开口， 即 壶嘴， 在加热结束后， 壶体 1内的热水通过壶嘴倒出。
在本实施例中， 所述加热管 4优选为玻璃加热管， 玻璃加热管比其他材质 的加热管更安全可靠。
参见图 2所示的热水机的结构示意图， 壶体 1位于热水机的机壳外部， 并 放置在热水机的底座 14上，第一供水管 2-1位于壶体 1的内部且与第一开口连 接； 第二供水管 2-2 (图 2中未示出）、 水泵 3、 加热管 4、 二通阀 8、 回水管 5 都设置在热水机的机壳内部， 即时出水口 6设置在热水机的机壳外部， 具体连 接关系参见图 1， 此处不再赘述。
在热水机上还设置有选择开关 10， 参见图 2所示， 用户通过选择开关 10 选择热水机实现传统电水壶或者即热式热水机的功能。
在热水机的底座 14内部还设置有控制电路板 13， 参见图 2所示， 所述控 制电路板 13是热水机的控制中心， 控制热水机的运行。
为了方便用户握取壶体 1， 参见图 2所示， 在壶体 1上还设置有手柄 12， 所述手柄 12朝向热水机的外侧， 方便用户握取。
在所述热水机上还设置有能够进行上下伸缩的弹性机构 11，参见图 2所示， 所述弹性机构 11设置在第二供水管 2-2 (图 2中未示出）与第一开口的连接处。 所述弹性机构 11是现有技术，与滴漏式咖啡机中的滴漏机构类似，此处不再赘 述。在将壶体 1放置到热水机的底座 14上时， 壶体 1的顶部挤压弹性机构 11， 使弹性机构 11处于伸缩状态，第二供水管 2-2与第一开口连接，且第二供水管 2-2与第一供水管 2-1在第一开口处对接。 在将壶体 1从热水机上取下时， 弹 性机构 11恢复原来的状态。
实施例二、 本实施例的热水机主要由壶体 1、 加热管 4、 即时出水口 6和 用于控制加热管 4的出水口处的水的流向的三通阀 9组成， 当需要加热管 4的 出水口处的水流入壶体 1时， 三通阀 9控制加热管 4的出水口处的水流向壶体 1，当需要加热管 4的出水口处的水从即时出水口 6流出时，三通阀 9控制加热 管 4的出水口处的水流向即时出水口 6， 参见图 3所示， 具体来说， 在壶体 1 上至少形成有两个开口： 第一开口和第二开口， 在第一开口和加热管 4的进水 口之间连接有供水管，加热管 4的出水口通过连接管 7连接三通阀 9的进水口， 三通阀 9的一个出水口通过回水管 5连接第二开口， 所述三通阀 9的另一个出 水口连接即时出水口 6。 在供水管上设置有水泵 3， 用于将壶体 1内的水抽出。
三通阀 9控制加热管 4的出水口处的水的流向， 控制原理如下： 当三通阀 9的进水口与三通阀 9的一个出水口连通时， 连接管 7与回水管 5连通，加热管 4的出水口处的水通过连接管 7流入回水管 5; 当三通阀 9的进 水口与三通阀 9的另一个出水口连通时， 连接管 7与即时出水口 6连通， 加热 管 4的出水口处的水通过连接管 7流向即时出水口 6。
当用户需要大量热水时， 即需要加热壶体 1内的整壶水时， 控制三通阀 9 的进水口与三通阀 9的一个出水口连通， 加热管 4的出水口处的水通过连接管 7流入回水管 5， 并通过第二开口流入壶体 1， 依次循环， 直至壶体 1内水达到 预定温度； 当用户即时需要少量热水时， 控制三通阀 9的进水口与三通阀 9的 另一个出水口连通，加热管 4的出水口处的水通过连接管 7流向即时出水口 6， 并通过即时出水口 6流出， 满足用户对少量热水的需求。
作为本实施例的一种优选设计方案， 所述供水管从第一开口处伸入到壶体 1的底部， 所述供水管分为两部分： 第一供水管 2-1和第二供水管 2-2， 第一供 水管 2-1位于壶体 1的内部且与第一开口连接， 第二供水管 2-2位于壶体 1的 外部且与第一开口连接，第一供水管 2-1和第二供水管 2-2在第一开口处对接。 水泵 3设置在第二供水管 2-2上， 将壶体 1内的水抽入到供水管， 并导入到加 热管 4中，经过加热管 4加热后，热水从加热管 4的出水口流入到连接管 7中， 并经由三通阀 9控制流向回水管 5或流向即时出水口 6。
所述加热管 4优选为竖直放置，加热管 4的进水口设置在加热管 4的底部， 加热管 4的出水口设置在加热管 4的顶部，供水管将水引入加热管 4的进水口， 并通过加热管 4的进水口进入加热管 4， 水在加热管 4内向上流动， 逐渐充满 整个加热管 4，最后经加热管 4的出水口流入连接管 7。由于加热管 4竖直放置， 从其底部进水口进入加热管 4的水， 会逐渐充满整个加热管 4， 防止加热管 4 局部干烧， 缩短其使用寿命。
第一开口和第二开口都设置在壶体 1的顶部， 壶体 1的底部无开口， 在壶 体 1内的水加热结束后， 可以将壶体 1单独取下， 热水通过第二开口倒出， 不 用担心壶体 1的底部漏水。 当然， 在所述壶体 1上还可以再形成一个开口， 即 壶嘴， 在加热结束后， 壶体 1内的热水通过壶嘴倒出。
在本实施例中， 所述加热管 4优选为玻璃加热管， 玻璃加热管比其他材质 的加热管更安全可靠。
本实施例的热水机中的其他部件， 如： 用于选择热水机是实现传统电水壶 还是即热式热水机功能的选择开关、 用于控制热水机运行的控制电路板、 设置 在壶体上的手柄、 能够进行上下伸缩的弹性机构等， 这些部件的结构和功能与 实施例一的热水机中的相应部件的结构和功能类似， 此处不再赘述。
当然， 上述说明并非是对本发明的限制， 本发明也并不仅限于上述举例， 本技术领域的普通技术人员在本发明的实质范围内所做出的变化、 改型、 添加 或替换， 也应属于本发明的保护范围。
