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。 With the development of society and the improvement of the level of science and technology, wall-hung boilers (also known as heating water heaters) are a kind of heating equipment that has a good family central heating function and can provide constant temperature hot water for family bathing and kitchen places. It is more and more widely used in people's lives. Wall-hung boilers usually use natural gas, artificial gas, or liquefied gas as fuel. The high-temperature flue gas generated by the combustion of the fuel heats the circulating water. The circulating water that carries the heat finally enters the radiator, floor heating pipe and other structures to increase the room temperature. Supply of domestic hot water.
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 When the wall-hung boiler does not need to be used for a long period of time (such as business trips, travel, etc.), the user needs to drain the boiler. However, although the amount of water in the wall-hung boiler can be basically drained, the water pressure sensor used to detect the water pressure of the drain has certain structural defects. The water pressure sensor will retain water that cannot be discharged naturally. The accumulated water in the water pressure sensor will continue to corrode the water pressure sensor. Moreover, in cold winter (low temperature environment), the water pressure sensor will be frozen by the standing water, which will cause the water pressure sensor to not work normally to detect the water pressure when the boiler is reused, which makes the unit unable to start the ignition operation, which seriously affects Use of fireplace. Moreover, the repair process of the water pressure sensor is very complicated, requiring maintenance personnel to open the main casing to remove the water pressure sensor for repair or replacement, which seriously affects the user experience and wastes a lot of manpower and material resources.

It can be understood that, in other embodiments, the heating device 100 may also be specifically other devices installed with a drainage device 20, such as a water heater, which is not limited herein.
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。 Please continue to refer to FIG. 1, the wall-hung boiler includes a main shell, and the main shell has a hollow shell structure to form a receiving cavity with a bottom wall 41. When the wall-hung boiler is installed on an installation surface (for example, a wall perpendicular to the ground), the bottom wall 41 of the main casing is parallel to the horizontal plane (the ground). The heat exchange device is contained in the accommodating cavity and located on the upper part of the main housing, and the drain device 20 is also contained in the accommodating cavity and located below the heat exchange device.
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。 The drainage device 20 includes a drainage pipe 21, a water pressure detection pipe 22, and a water pressure sensor 23.

The water pressure detecting pipe 22 and the drain pipe 21 have a preset angle to make the central axis of the water pressure sensor 23 Parallel to the direction of gravity.
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。 In this way, since the water pressure sensor 23 is indirectly connected to the drain pipe 21 through the water pressure detection tube 22, the central axis of the water pressure sensor 23 can be parallel to the direction of gravity, and the water in the water pressure sensor 23 can pass through the water pressure detection tube under the action of gravity. 22 automatically flows into the drain pipe 21, so no accumulated water remains in the water pressure sensor 23, thereby preventing the water pressure sensor 23 from freezing and being damaged in a low temperature environment while satisfying the water pressure measurement, and avoiding the water pressure sensor from being corroded by the accumulated water.
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。 The drain pipe 21 includes a water inlet 212 and a water outlet 214 that are connected to each other. The water inlet 212 is connected to the heat exchange device. The outlet 214 is connected to one end of the outlet valve 24, and the other end of the outlet valve 24 is connected to the three-way valve 25. The three-way valve 25 is used to connect structures such as heating pipes. In this way, the hot water output from the heat exchange device can enter the drain pipe 21 through the water inlet 212 of the drain pipe 21, then enter the water outlet valve 24 through the water outlet 214, and finally flow into the heating pipe and other structures through the three-way valve 25. Specifically, in this embodiment, the drain pipe 21 extends downward from an end connected to the main housing substantially in a vertical direction. It can be understood that in other embodiments, the shape of the drain pipe 21 is not limited to this, and can be set as required.
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。 In some embodiments, the water pressure detection tube 22 is connected to the drain tube 21 by welding or the like, and may also be connected to the drain tube 21. One piece. The water pressure detection tube 22 is bent and extends from an end connected to the drain tube 21 toward the water inlet end 212 of the drain tube 21, and includes a connecting end and a mounting end that communicate with each other, and the center axis of the mounting end is parallel to the direction of gravity. The connecting end is connected to the drain pipe 21, one end of the water pressure sensor 23 is inserted into the installation end to obtain the water pressure, and the other end extends out of the installation end. Since the water pressure detecting pipe 22 is directly connected with the drain pipe 21, the water pressure sensor 23 can detect the water pressure in the drain pipe 21 through the water pressure detecting pipe 22. Since the water pressure detection tube 22 is bent and extended in the direction of the water inlet 212 so that the central axis of the mounting end is parallel to the direction of gravity, the central axis of the water pressure sensor 23 inserted in the mounting end must be parallel to the direction of gravity and is used to detect water pressure. One end is facing down. In this way, when the wall-hung boiler is drained, the water in the water pressure sensor 23 is automatically discharged and drained under the action of gravity without being stored in the water pressure sensor 23, and no other pumping mechanism is required.
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。 In an embodiment, the drainage device 20 further includes a heating unit (not shown), and the heating unit is installed on the side of the water pressure sensor 23 to heat the water pressure sensor 23. In this way, when the temperature of the wall-hung boiler is too low, the heating unit can be activated regularly to prevent the residual freezing in the water pressure sensor 23, thereby further ensuring that the water pressure sensor 23 will not be damaged by freezing.
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。 The above-mentioned drainage device 20 and the heating equipment 100 provided with the drainage device 20 can be installed in the direction of gravity because the water pressure sensor 23 is installed on the drainage pipe 21 through the water pressure detection pipe 22, so that the water pressure detection can be prevented while preventing The water pressure sensor 23 is corroded and frozen by the water that cannot be drained, thereby ensuring that the heating device 100 can resume normal operation after draining, improving user experience, saving maintenance costs, and is different from the inventor’s understanding of only horizontal The installed water pressure sensor is likely to retain water, which may cause the water pressure sensor 23 to be corroded or frozen by the water. In addition, the structure of the drainage device 20 is simple, which realizes the antifreeze function of the water pressure sensor while avoiding the increase in production cost. The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, all possible combinations of the technical features in the above-mentioned embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, All should be considered as the scope of this specification.
