排水装置及设有其的采暖设备
相关申请
本公开要求 2019年 02月 25日申请的, 申请号为 201910155231. 2, 名称为“排水装 置及设有其的采暖设备” 的中国专利申请的优先权, 在此将其全文引入作为参考。 技术领域
本公开涉及热交换设备领域, 特别是涉及一种排水装置及设有其的采暖设备。 背景技术
随着社会的发展与科学技术水平的提高, 壁挂炉 (又称采暖热水炉) 作为一种具有良 好的家庭中央供暖功能, 并且能够提供恒温热水供家庭沐浴、 厨房场所使用的供暖设备, 在人们的生活中的应用越来越广泛。 壁挂炉通常以天然气、 人工煤气或液化气等物质作为 燃料, 通过燃料燃烧产生的高温烟气加热循环水, 携带热量的循环水最终进入暖气片、 地 暖管等结构实现房间增温, 也可实现生活热水的供应。
在较长一段时间内不需使用壁挂炉时 (例如出差、 旅行等情况), 用户需要对壁挂炉 进行排水操作。 但是, 虽然壁挂炉内的水量可以基本排净, 但用于检测排水水压的水压传 感器存在一定的结构缺陷, 水压传感器的内部会存留无法自然排出的积水。 存留在水压传 感器内部的积水会持续对水压传感器产生腐蚀作用。 而且在寒冷的冬天 (低温环境), 积 水会冻结水压传感器,导致壁挂炉在被重新使用时,水压传感器无法正常工作以检测水压, 进而致使机组无法进行开机点火操作, 严重影响了壁挂炉的使用。 而且, 水压传感器的维 修过程十分复杂, 需要维修人员打开主机壳拆下水压传感器进行维修或更换, 从而严重影 响了用户的使用体验, 并且浪费大量人力物力。 发明内容
基于此, 有必要针对排水后的壁挂炉的水压传感器中存在积水的问题, 提供一种可基 本排尽水压传感器中存留积水的排水装置及设有其的采暖设备。
一种排水装置, 所述排水装置包括排水管、 水压检测管以及水压传感器, 所述排水管 包括相互连通的进水端及出水端, 所述水压传感器通过所述水压检测管连接于所述排水管 的所述进水端与所述出水端之间, 所述水压检测管与所述排水管呈预设夹角以使所述水压 传感器的中心轴线平行于重力方向。 上述排水装置, 由于水压传感器通过水压检测管间接连接排水管, 因此水压传感器的 中心轴线可平行于重力方向, 水压传感器中的水可在重力作用下经水压检测管自动流入排 水管, 所以没有积水留存在水压传感器中, 从而在满足水压测量的同时防止水压传感器在 低温环境下冻结损坏, 并且避免水压传感器受到积水的腐蚀。
在其中一个实施例中, 所述水压检测管自连接所述排水管的一端向所述排水管的所述 进水端方向弯曲延伸。
在其中一个实施例中, 所述水压检测管包括相互连通的连接端与安装端, 所述连接端 连接于所述排水管, 所述水压传感器的一端插设于所述安装端, 另一端伸出所述安装端。
在其中一个实施例中, 所述安装端的中心轴线平行于重力方向。
在其中一个实施例中, 所述排水装置还包括出水阀, 所述出水阀连接于所述排水管的 所述出水端。
在其中一个实施例中, 所述排水装置还包括三通阀, 所述三通阀连接于所述出水阀远 离所述排水管一端。
在其中一个实施例中, 所述排水装置还包括加热单元, 所述加热单元安装于所述水压 传感器一侧以加热所述水压传感器。
一种采暖设备, 包括上述的排水装置。
在其中一个实施例中, 所述采暖设备包括主壳体, 所述主壳体开设有具有底壁的容纳 腔, 所述排水装置收容于所述容纳腔内, 所述排水装置的所述水压传感器的中心轴线垂直 于所述底壁。
在其中一个实施例中, 所述采暖设备为壁挂炉。 附图说明
图 1为本公开的实施例的采暖设备的部分结构的结构示意图。 具体实施方式
为了便于理解本公开, 下面将参照相关附图对本公开进行更全面的描述。 附图中给出 了本公开的较佳实施例。 但是, 本公开可以以许多不同的形式来实现, 并不限于本文所描 述的实施例。 相反地, 提供这些实施例的目的是使对本公开的公开内容的理解更加透彻全 面。
需要说明的是, 当元件被称为“固定于”另一个元件, 它可以直接在另一个元件上或 者也可以存在居中的元件。 当一个元件被认为是“连接”另一个元件, 它可以是直接连接 到另一个元件或者可能同时存在居中元件。 本文所使用的术语“垂直的”、 “水平的”、 “左”、 “右” 以及类似的表述只是为了说明的目的。
除非另有定义, 本文所使用的所有的技术和科学术语与属于本公开的技术领域的技术 人员通常理解的含义相同。 本文中在本公开的说明书中所使用的术语只是为了描述具体的 实施例的目的, 不是旨在于限制本公开。 本文所使用的术语“及 /或”包括一个或多个相 关的所列项目的任意的和所有的组合。 如图 1所示, 本公开的实施例的一种采暖设备 100, 采暖设备 100包括换热装置 (图 未示) 以及排水装置 20, 排水装置 20用于输送换热装置输出的热水至采暖管道等结构。
下面以采暖设备 100为壁挂炉为例, 对本申请的中排水装置 20的结构进行说明。 下 列实施例仅用以作为范例说明, 并不会限制本申请的技术范围。 可以理解, 在其它实施例 中, 采暖设备 100也可具体为安装有排水装置 20的其它装置, 例如热水器等, 在此不作 限定。
请继续参阅图 1, 壁挂炉包括主壳体, 主壳体呈中空的壳体结构以形成具有底壁 41的 容纳腔。 当壁挂炉安装于安装面 (例如垂直于地面的墙壁) 上时, 主壳体的底壁 41平行 于水平面 (地面)。 换热装置收容于容纳腔内并位于主壳体的上部, 排水装置 20也收容于 容纳腔内并位于换热装置下方。
排水装置 20包括排水管 21、 水压检测管 22以及水压传感器 23。 水压传感器 23通过 水压检测管 22连接于排水管 21的进水端 212与出水端 214之间, 水压检测管 22与排水 管 21呈预设夹角以使水压传感器 23的中心轴线平行于重力方向。
如此, 由于水压传感器 23通过水压检测管 22间接连接排水管 21, 因此水压传感器 23的中心轴线可平行于重力方向, 水压传感器 23中的水可在重力作用下经水压检测管 22 自动流入排水管 21, 所以没有积水留存在水压传感器 23中, 从而在满足水压测量的同时 防止水压传感器 23在低温环境下冻结损坏, 并且避免水压传感器受到积水的腐蚀。
其中, 排水管 21包括相互连通的进水端 212及出水端 214, 进水端 212与换热装置连 通, 出水端 214连接出水阀 24的一端, 出水阀 24的另一端连接三通阀 25, 三通阀 25用 于连接采暖管道等结构。 如此, 换热装置输出的热水可通过排水管 21的进水端 212进入 排水管 21中, 然后通过出水端 214进入出水阀 24中, 最后通过三通阀 25流入采暖管道 等结构。 具体在本实施例中, 排水管 21大致沿竖直方向自连接主壳体的一端向下方延伸。 可以理解, 在其它实施例中, 排水管 21的形状不限于此, 可根据需要设置。
在一些实施例中, 水压检测管 22通过焊接等方式连接于排水管 21, 也可与排水管 21 一体成型。 水压检测管 22自连接排水管 21的一端向排水管 21的进水端 212方向弯曲延 伸, 包括相互连通的连接端与安装端, 且安装端的中心轴线平行于重力方向。 其中, 连接 端连接于排水管 21, 水压传感器 23的一端插设于安装端内以获取水压, 另一端伸出安装 端。 由于水压检测管 22与排水管 21直接连通, 因此水压传感器 23可通过水压检测管 22 检测排水管 21内的水压。 由于水压检测管 22向进水端 212方向弯曲延伸而使安装端的中 心轴线平行于重力方向, 因此插设于安装端的水压传感器 23的中心轴线必然平行于重力 方向且用于检测水压的一端朝下。 如此, 当壁挂炉排水时, 水压传感器 23中的水在重力 作用下自动流出排尽而不会存留在水压传感器 23内, 且无需设置其它抽水机构。
在一实施例中, 排水装置 20还包括加热单元 (图未示), 加热单元安装于水压传感器 23—侧以加热水压传感器 23。 如此, 当壁挂炉的温度过低时, 加热单元可定时启动以防 止水压传感器 23中残留的冻结, 从而进一步保证水压传感器 23不会冻结损坏。
上述排水装置 20及设有该排水装置 20的采暖设备 100, 由于水压传感器 23通过水压 检测管 22安装于排水管 21而可沿重力方向设置, 因此在保证水压检测的同时, 可防止水 压传感器 23被无法排尽的积水腐蚀和冻结, 从而保证了采暖设备 100在排水后可重新正 常工作, 提升了用户体验, 节省了维修成本, 而不同于发明人所了解的仅能横向安装的水 压传感器容易存留积水而导致水压传感器 23被积水腐蚀或冻结。 此外, 排水装置 20的结 构简单, 在实现了水压传感器的防冻功能的同时避免了生产成本的增加。 以上所述实施例的各技术特征可以进行任意的组合, 为使描述简洁, 未对上述实施例 中的各个技术特征所有可能的组合都进行描述, 然而, 只要这些技术特征的组合不存在矛 盾, 都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本公开的几种实施方式, 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, 在不脱离本公开构思的前提下, 还可以做出若干变形和改进, 这些都属于本公开的保护范 围。 因此, 本公开专利的保护范围应以所附权利要求为准。
