Description

即热式热水产生装置 技术领域
本发明涉及一种即热式热水产生装置， 特别是涉及一种电加热型即热式 热水产生装置。 背景技术
电加热型即热式热水产生装置与保温式热水产生装置的不同之处在于： 在不需要热水时， 其无需消耗电能来对热水继续保温； 而当需要热水时， 其 可以在短短的数秒钟内（3-10秒）产生所设定的温度的热水。 图 1A及图 1B 示出了传统的电加热型即热式热水产生装置，其包括内部形成通道 3的热水 管 1和包覆在热水管外的发热元件 2。 工作时， 待加热的水从热水管 1的一 端输入， 流经热水管的通道并受发热元件加热， 最后从热水管另一端输出。 然而， 此类即热式热水产生装置的缺点在于， 其工作时所需电力非常庞大， 通常需要超过 10000瓦功率， 而导致需要重新配置电源电线。这使得使用该 即热式热水产生装置非常不方便， 影响了使用者的使用意愿。 另外， 传统即 热式热水产生装置产生的水量较小，且热水温度不高或加热不均匀， 而无法 正常使用。 传统即热式热水产生装置的上述问题使得其无法进入实用阶段， 当然也就无法为使用者所接受。 发明内容
针对上述问题， 本发明的主要目的在于提供一种可提高发热元件热效率 的即热式热水产生装置， 其可以均匀充分对待加热的水进行加热， 从而提高 发热元件的热效率， 降低能源损耗。
该即热式热水产生装置包括： 热水管， 其内部沿长度方向形成通道， 以 供待加热的水流通； 第一加热元件， 其包覆于该热水管外； 分流柱， 其沿该 热水管长度方向设置于该通道内； 分流柱固定架， 其用于将该分流柱固定于 该通道的中心位置， 并构成为不阻断该通道的形式。
该第一发热元件可以是半导体发热电阻薄膜， 其通过第一导电极与外部 电源相连接， 以受该外部电源供电。 该分流柱固定架可以呈十字架形状、 三叉戟形状或者其他适当形状。 该热水管可以由玻璃或陶瓷制成， 或者由金属制成并在其外表面上涂覆 绝缘涂层； 而该分流柱和分流柱固定架可以由塑料、玻璃、 陶瓷或金属制成。
该热水管和该分流柱垂直于长度方向的横截面可以呈圓形、 矩形或者椭 圓形。
另外， 该分流柱的内部沿其长度方向可以形成空腔， 该空腔内壁附着有 第二加热元件。 该第二发热元件可以是半导体发热电阻薄膜， 其通过第二导 电极与外部电源相连接， 以受该外部电源供电。
此时， 该分流柱可以由塑料、 玻璃或陶瓷制成， 或者由金属制成并在其 外表面上涂覆绝缘涂层。 附图说明
下面参照附图详细描述本发明， 其中：
图 1A是传统的即热式热水产生装置的示意图；
图 1B是图 1A所示的即热式热水产生装置的俯视图；
图 2A是本发明的即热式热水产生装置的第一实施方式的示意图； 图 2B和图 2C分别是图 2A所示的即热式热水产生装置的纵向剖视图和 俯视图；
图 3A是本发明的即热式热水产生装置的第二实施方式的示意图； 图 3B和图 3C分别是图 3A所示的即热式热水产生装置的纵向剖视图和 俯视图；
图 4A是本发明的即热式热水产生装置的第三实施方式的示意图； 图 4B和图 4C分别是图 4A所示的即热式热水产生装置的纵向剖视图和 俯视图；
图 5A是本发明的即热式热水产生装置的第四实施方式的示意图； 以及 图 5B是图 5A所示的即热式热水产生装置的俯视图。 具体实施方式
图 2A-图 2C示出了本发明的即热式热水产生装置的第一实施方式， 其 包括： 热水管 21 , 其内部沿长度方向形成通道 23 , 以供待加热的水流通； 加 热元件 22, 例如， 半导体发热电阻薄膜， 其包覆于热水管 21外； 分流柱 24, 其沿热水管 21长度方向设置于该通道 23内； 以及分流柱固定架 25, 其用于 将分流柱 25固定于该通道 23的中心位置。该加热元件可经由导电极 23与外 部电源相连接， 以由外部电源向其供电。该分流柱固定架 25形成为十字架形 式， 如图 3所示， 以免阻断通道 23。 该分流柱固定架 25也可以形成为三叉 戟或者其他适当的形式， 只要其不阻断该通道即可。
由于分流柱的分流作用， 进入热水管的待加热的水将沿着通道内壁流 动， 从而可以更加均匀、 高效地受发热元件加热。 由此， 本发明的即热式热 水产生装置的热效率得以大幅提高。
该热水管可以由玻璃、 陶瓷制成， 或者由金属制成并在其外表面上涂覆 绝缘涂层； 而该分流柱和分流柱固定架可以由塑料、 玻璃、 陶瓷、 金属等材 料制成。
图 3A-图 3C示出了本发明的即热式热水产生装置的第二实施方式， 其 包括热水管 31、 热水管内的通道 33、 加热元件 32、 分流柱 34、 分流柱固定 架 35以及导电极 36, 这些元件及其相互关系与第一实施方式中的类似。 与 第一实施方式不同的是，该第二实施方式中的分流柱 34内部沿其长度方向形 成空腔 37 , 该空腔 37内壁附着有加热元件 38, 例如， 半导体发热电阻薄膜。 该加热元件 38可以经由设置于空腔 37内的导电极 39与外部电源相连接，以 由外部电源向其供电。
由于分流柱的分流作用， 进入热水管的待加热的水将沿着通道内壁， 从 而可以更加均匀、 高效地受加热管外和分流柱内的发热元件加热。 由此， 本 发明的即热式热水产生装置的热效率得以大幅提高。
该热水管可以由玻璃、 陶瓷制成， 或者由金属制成并在其外表面上涂覆 绝缘涂层； 而该分流柱可以由塑料、 玻璃、 陶瓷等材料制成， 或者由金属制 成并在其外表面上涂覆绝缘涂层。
如图 2C和图 3C所示， 第一和第二实施方式中热水管和分流柱的横截 面呈圓形，但也可以呈其他形状。 例如， 图 4A-图 4C示出了示出了本发明的 即热式热水产生装置的第三实施方式， 其中热水管 41和分流柱 44的横截面 呈矩形， 除此之外， 第三实施方式中的其他元件及其相互关系与第一或第二 实施方式中的类似。 虽然， 图 4B示出分流柱 44内部形成空腔并装设有加热 元件， 但是其也可以和第一实施方式中的类似， 形成无内部空腔的实体。
图 5A和图 5B示出了示出了本发明的即热式热水产生装置的第四实施 方式， 其中热水管 51的横截面呈椭圓形， 除此之外， 第四实施方式中的其他 元件及其相互关系与第一、 第二或第三实施方式中的类似。 为简化起见， 图 5A和图 5B中未示出分流柱， 该分流柱的横截面也相应地呈椭圓形。
在本发明的即热式热水产生装置的基础上， 安装温度检测装置、 电力控 制装置、 水量控制装置等就可以实现产生所需水量和温度的热水， 并可以提 高该热水产生装置的热效率， 降低能源消耗。
尽管参照优选的实施例描述了本发明，但本发明并不限于此，本领域的普 通技术人员在不脱离本发明的精神和范围的前提下，可以对本发明进行各种 改进和变形。
