Definitions

  • This invention belongs to the field of household appliance technology, specifically relating to a condensate draining device and a condensing gas water heater and drainage method.
  • Gas water heaters are widely used due to their energy-saving and environmentally friendly characteristics. They preheat cold water by absorbing the residual heat of the high-temperature flue gas produced by combustion, thus improving the thermal efficiency of the gas water heater.
  • water vapor in the high-temperature flue gas condenses into a large amount of liquid water in the condenser. Since the high-temperature flue gas produced by natural gas combustion contains a large amount of acidic substances (carbon oxides, sulfur oxides, nitrogen oxides, etc.), which dissolve in the water, making the water acidic. The disposal of this water is a problem that needs to be addressed.
  • Existing technologies disclose methods for forming water mist, which is intended to be discharged through a flue pipe.
  • existing technologies also disclose a water atomization emission device and a condensing gas water heater.
  • a first row of fans is located below a sprinkler, and a second row of fans is located directly in front of the first row of fans and vertically distributed.
  • Water droplets fall onto the blades of the first row of fans below, and the rotating blades turn the water droplets into ultra-fine mist droplets, forming water vapor that dissolves into the air.
  • the water vapor moves upward and enters the atomization emission pipe. Under pressure, the water finally enters the flue pipe and is discharged outdoors with the flue gas.
  • the technical solution has flaws that prevent its application.
  • the main problem in actual experiments is that the airflow generated by the two fans interferes with each other.
  • both fans need high power. This results in strong wind fields around the fans and mutual interference.
  • the two fans consume a lot of energy and require an additional power supply.
  • Some solutions involve adding neutralizing agents to the water to neutralize acidic water before pumping it into the gas heater's tap water supply for domestic use.
  • the neutralized water may still contain acidic, alkaline, or other chemical components, which can harm users, causing allergies, skin irritation, or burns.

Description

一种冷凝水排出装置及冷凝式燃气热水器与排水方法 技术领域
本发明属于家用电器技术领域，具体涉及一种冷凝水排出装置及冷凝式燃气热水器与排水方法。
 背景技术
燃气热水器基于自身节能、环保的特点而被广泛普及使用，通过吸收燃烧产生的高温烟气的余温而预热冷水，达到提高燃气热水器热效能的效果。但是，燃气热水器的冷凝器在预热冷水的过程中，高温烟气中的水蒸气在冷凝器内遇冷凝结产生大量的液态水，由于天然气燃烧产生的高温烟气含有大量酸性物质（碳氧化物、硫氧化物、氮氧化物等），并溶解在水中，使水呈酸性，而水的排放是有待解决的问题。
目前，市面上的燃气热水器都要预留水排水口，在安装时预留排水管，使用时单独连接地漏；或者在水排水口处设置临时存水容器，并要求用户频繁倒水；或者或连接其它特殊的排放通道排放水。这种增加安装成本以及复杂性的方案不受欢迎，急需要提供一种不改变燃气热水器主体结构以及安装方式的除水方案。
现有技术公开了将水形成水雾，希望随着排烟管排出，具体的，现有技术还公开了一种水雾化排放装置及冷凝式燃气热水器，第一排风扇设置在洒水器下方，第二排风扇位于第一排风扇正前方并且垂直分布，水滴到下方的第一排风扇的叶片上面，旋转的叶片将滴落在上面的水形成超微小的雾滴，形成水汽溶入空气中，在第二排风扇的风力作用下向上运动，进入到雾化排放管内，随着压力作用，最终进入到排烟管中，随烟气一起排放到室外。该技术方案存在缺陷导致其无法应用，实际实验中最主要的问题是两风扇形成的气流互相干扰，尤其是为了将滴落在上面的水形成超微小的雾滴以及将水汽向上运动进入到雾化排放管，两风扇都需要大功率，此导致风扇周边风场强且互相干扰，实况发现水滴无法有效落在叶片上，少量形成的水汽不易排出，排烟管口只见少量水汽，反而壳内回流明显，导致该结构无法应用；而且两个风扇能耗高，需要额外设置电源。
因此，需要研发新的结构，可以有效的将燃气热水器内的水排出且能耗低，无需额外设置电源。
 技术问题
目前，现有技术一般采用冷凝水雾化的方式实现冷凝式燃气热水器冷凝水排放的目的，通过高压或高速气源驱动雾化喷嘴，形成高速或高压气流，将酸性冷凝水逐渐分解成细小颗粒，经过排烟管排放至室外。然而，利用高压或高速气源需要消耗大量的能耗，违背了冷凝式燃气热水器节能设计初衷，同时在工作过程中，气源设备大多处于承载高压的状态，具有一定安全风险，若气源压力不足，会导致雾化颗粒逐渐变大，严重影响雾化效果和冷凝水排出速度。尤其是现有燃器预留电源无法驱动，现有技术的结构都需要额外装电源，此限制现有雾化排水的应用甚至被燃器厂家抵触。
目前，市面上的燃气热水器都要预留冷凝水排水口，在安装时预留排水管，使用时单独连接地漏；或者在水排水口处设置临时存水容器，并要求用户频繁倒水；或者或连接其它特殊的排放通道排放水，这种增加安装成本以及复杂性的方案不受欢迎。
有些方案在水中加入中和物质的方式，对酸性水进行中和，然后泵入燃器的自来水管道中，供用户当作生活水使用。然而，中和后的水仍然可能具有酸性成分或碱性成分或其他化学成分，会对用户的正常使用带来伤害，例如过敏或皮肤刺激、灼伤等。同时，中和物质为消耗品，随着冷凝式燃气热水器的使用，性能也会发生变化，需要定期加装或更换，否则水会持续呈酸性，存在风险。
还有些方案，对酸性冷凝水采用电加热或者燃烧加热的方式，或者采用其他让冷凝水挥发的方法。此类方案，或者需要消耗大量的能量，违背了冷凝式燃气热水器节能的目标。或者排出冷凝水的速度过慢，无法达到冷凝水的产生速度，因而不具备实用性。
因此，针对以上问题和技术需求，有必要对现有的冷凝水排出装置进行改进。
 技术解决方案
针对上述问题，本发明的目的在于提供一种冷凝水排出装置及冷凝式燃气热水器与排水方法，能够将燃烧废气中水汽液化产生的水排出，安全可靠。
本发明利用水泵抽水，实现冷凝水输送效率高的效果，较没有水泵的方案好，提高了冷凝水的雾化效率和排放效率，出乎意料的，本发明解决了现有方法存在的冷凝水在排烟管端口滴水的问题，这是其他结构无法实现的；尤其是，本发明冷凝水排出装置能耗低，利用现有燃器预留电源足够驱动，克服了现有技术采用高压喷嘴等结构需要额外装电源的问题。
本发明利用自吸式雾化结构，占用空间小、成本低，水雾化和排出效率高，特别的，旋转盘的驱动设备能耗较低，与水泵抽水相比，对燃器预留电源的额度要求低。主要的是，自吸式雾化结构将燃烧废气中水汽液化产生的水雾化再经排烟管排出时，高雾化效果避免了含酸性物质水带来的问题，而且扩散快，可以被空气稀释。
本发明可以有效的将燃气热水器内的水排出且能耗低，无需额外设置电源；尤其是，无需额外设置水输送动力设备，输水管使得水自流至旋转盘上，兼顾除水效率以及低能耗，还降低了耗材成本，也能将水完全排出。

对照例一
现有评价较好的市售植保机雾化喷头，根据其产品描述特点为雾化效果更好，适合机雾炮机以及喷药，但是结合至热水器除水，实验可知效果不佳。
实验方法：在实验室条件下，分别取1.3L的水加入冷凝水室进行20分钟实验，仅启动热水器燃烧控制风扇、电机（最大转速）、水泵（如有）、辅助风扇（若有），排烟管（水平放置）出口下方放小桶收集滴水（此为现有技术存在的问题）；各结构除水表征见表1，本发明旋转盘转动，水被射出并与水雾化装置碰撞形成雾，雾从排烟管排出，不仅具有高的排放效率，而且排放过程雾化占比高。雾化占比=（1-排烟管出口收集的水）/除去的水×100%；除去的水=1.3-集水腔剩余的水；以上水的单位为L。

本发明水泵抽水旋水碰撞雾化的方式明显取得高的排水效率，为目前实验上最高的，而且雾化占比出乎意料的接近100%，排烟管口未见滴水现象；尤其是，在排烟管向上倾斜一定角度的严苛试验条件下，排水效率依然高，且避免了冷凝水滴在建筑外表面，造成对建筑物外表面腐蚀的现象。
实施例十六
本发明公开了利用上述冷凝水排出装置进行燃气热水器冷凝水处理的方法，包括以下步骤：
（1）燃气热水器开始工作，自来水经过冷凝器进入热交换器，天然气加热热交换器，以加热冷水，同时产生高温烟气；
（2）高温烟气在燃烧控制风扇的作用下进入冷凝器，进行冷水预热，高温烟气中的水在冷凝室内遇冷产生的水进入冷凝水室；

本发明公开了一种冷凝水排出装置及包含该装置的冷凝式燃气热水器，包括自吸式雾化结构以及冷凝室和排烟管，自吸式雾化结构位于冷凝室内或冷凝室外；自吸式雾化结构为冷凝水排出装置，其中自吸装置的另一端与冷凝室的水箱连通。冷凝室用于预热冷水，排烟管为燃器常规设置的外接管道，燃器燃烧产生的废气通过排烟管排放到室外；自吸式雾化结构可以将冷凝室产生的水雾化形成水雾，随废气一并排放到室外。自吸装置的一端与旋转盘连通，另一端与冷凝室的水箱连通，可以将燃烧废气中水汽液化产生的水雾化。当自吸式雾化结构位于冷凝室外时，还包括排气管，排气管与排烟管连通，自吸式雾化结构与排气管形成气体连通结构，可以将燃烧废气中水汽液化产生的水雾化再经排烟管排出；当自吸式雾化结构位于冷凝室内时，优选还包括排气管，排气管与排烟管连通，自吸式雾化结构与排气管形成气体连通结构，可以将燃烧废气中水汽液化产生的水雾化再经排烟管排出。优选的，水雾化装置的部分或者全部位于排气管内，利于将燃烧废气中水汽液化产生的水雾化再经排烟管排出。
作为优选，所述旋转盘驱动器上还设有扇叶，扇叶位于自吸装置上方。旋转盘驱动器同时驱动旋转盘与扇叶转动，扇叶给与抽力，加速水雾的排放速度，提高水的排放效率。
本发明中，冷凝室用于预热冷水，排烟管为外接管道，是燃气热水器的常规部件，燃气热水器内的废气通过排烟管排放到室外，自吸式雾化结构用于将冷凝室产生的水转变成水雾，随废气一并排放到室外。实际应用过程中，冷凝室的上表面留有一段管道作为排气管，自吸式雾化结构位于冷凝室内时，可以设置在冷凝室内部（管道外），也可以设置在冷凝室上表面的管道内部；自吸式雾化结构位于冷凝室外时，可以额外设置一根排气管，自吸式雾化结构设于排气管内，排气管、排烟管连通，将燃烧废气中水汽液化产生的水雾化再经排烟管排出。

在先技术公开了一种燃气热水器，通过设置常规高压雾化喷嘴（68.4W）对水进行雾化，辅助风扇（14.4W）加速水雾排出排烟管，以实现水排放的目的。按照其使用方法，之前的实验可知，排放效率为940mL/h，雾化占比不到40%，而且需要辅助风扇，否则排放效率低于500 mL/h。目前市面上出售的吸水式雾化嘴体积大，无法用于燃气热水器，而且功率高（150W），因此需要开发新的结构，本发明公开了一种自吸式雾化结构及其在燃器中的应用，该自吸式雾化结构包括旋转盘、自吸装置、旋转盘驱动器、水雾化装置，旋转盘与旋转盘驱动器连接并由其控制转动；自吸装置设于旋转盘的下方，与旋转盘连通，可以将水在转动吸力作用下吸至旋转盘表面；水雾化装置位于旋转盘边缘或外侧，用以将旋转盘甩出的水碰撞雾化。本发明自吸式雾化结构用于冷凝式燃气热水器，将其废气中水汽液化产生的水排出，效率高，而且有效缓解了现有排水结构存在的滴水问题，尤其是，本发明雾化占比超过95%，可以在燃器中得以应用。

自吸式雾化结构位于冷凝室内，电机、格栅分别通过支座安装在排气管一端内，支座以及安装方法为常规技术，可以固定电机、格栅即可，工作中，格栅不动，冷凝室水箱内的水通过水管自吸至旋转盘上，电机驱动旋转盘转动形成自吸力，并且水随转动的旋转盘甩出，与格栅碰撞，从而转变成水雾，排气管、排烟管连通，将燃烧废气中水汽液化产生的水雾化再经排烟管排出。
实验方法：在实验室条件下，分别取1.2L的水加入集水腔进行20分钟实验，仅启动热水器燃烧控制风扇、电机（最大转速），排烟管出口下方放小桶收集滴水；本发明旋转盘转动，水被射出并与格栅碰撞形成雾，雾从排烟管排出，不仅具有高的排放效率，而且排放过程雾化占比高。雾化占比=（1-排烟管出口收集的水）/除去的水×100%；除去的水=1.2-集水腔剩余的水；以上水的单位为L，排烟管出口收集的水为滴水，是现有技术的问题之一。
实验时，将排烟管出口斜向上15°，排烟管向上倾斜一定角度的严苛试验条件下，排水效率依然高，且避免了冷凝水滴在建筑外表面，造成对建筑物外表面腐蚀的现象。

实施例二十五
上述燃气热水器工作中除水的过程为：
（1）燃气热水器开始工作，自来水经过冷凝室进入热交换器，天然气加热热交换器，以加热冷水，同时产生高温烟气；电机启动，旋转盘转动，此时也可以不开电机，等待水箱中的水集到一定高度再开启，具体为常规技术；
（2）高温烟气在燃烧控制风扇的作用下进入冷凝室，进行冷水预热，高温烟气中的水在冷凝室内遇冷产生的水进入水箱；
（3）冷凝室水箱内的水通过水管自吸至旋转盘上，电机驱动旋转盘转动形成自吸力，并且水随转动的旋转盘甩出，与格栅碰撞，从而转变成水雾，排气管、排烟管连通，将燃烧废气中水汽液化产生的水雾化再经排烟管排出，被排放到室外。
进一步的，可以采用常规控制器控制电机的工作，冷凝室的水箱内设有水位传感器，水达到设定的高度时，中央控制单元控制电机开启或加速，加快旋转盘的转动速度，加快除水。
冷凝式燃气热水器基于自身节能、环保的特点而被广泛普及使用，通过吸收燃烧产生的高温烟气的余温而预热冷水，达到提高燃气热水器热效能的效果。但是，冷凝式燃气热水器的冷凝室在预热冷水的过程中，高温烟气中的水蒸气在冷凝室内遇冷凝结产生大量的液态水，由于天然气燃烧产生的高温烟气含有大量酸性物质（碳氧化物、硫氧化物、氮氧化物等），并溶解在水中，使水呈酸性，而水的排放是有待解决的问题。本发明将冷凝室水箱内的水通过水管自吸至旋转盘上，电机驱动旋转盘转动形成自吸力，并且水随转动的旋转盘甩出，与格栅碰撞，从而转变成水雾，排气管、排烟管连通，将燃烧废气中水汽液化产生的水雾化再经排烟管排出，被排放到室外。现有技术导致排烟管口出现滴水问题；本发明采用新的结构，冷凝室水箱内的水通过自吸装置自吸至旋转盘上，旋转盘驱动器驱动旋转盘转动形成自吸力，并且水随转动的旋转盘甩出，与水雾化装置碰撞，从而转变成水雾，水雾化和排出效率高，有效缓解了现有排水结构存在的滴水问题。主要的是，自吸式雾化结构将燃烧废气中水汽液化产生的水雾化再经排烟管排出时，高雾化效果避免了含酸性物质水带来的问题，而且扩散快，可以被空气稀释。
本发明公开了一种冷凝水排出装置及包含该装置的冷凝式燃气热水器，燃气热水器工作时，冷凝器产生的水由水输送结构流至旋转盘上；第一驱动设备带动旋转盘转动，水被射出并与水雾化装置碰撞形成雾；雾从排烟管排出，完成燃气热水器的除水。与现有水泵输水不同，本发明以水管作为水输送结构，其一端连通冷凝器的集水腔，另一端置于旋转盘处，能够使得水在无需设置水输送动力设备的情况下自流至旋转盘上；不仅兼顾除水效率以及低能耗，还降低了耗材成本，尤其是解决了现有技术存在的多风场互相干扰的问题，特别是不会对燃烧控制风扇产生影响。
本发明中，旋转盘表面为承接水的一面，优选为光滑结构，现有技术大都在旋转盘表面设置例如导流槽凹凸结构，本发明没有采用现有技术常规技术，以光滑的旋转盘取得更好的技术效果，出乎人们预料。一般的，旋转盘本体的横截面为圆，其可以为碗状结构、圆柱结构、圆台结构或倒圆台结构圆锥结构或倒圆锥结构、单层或多层结构，或其他结构，能够承接水并转动将水射出与水雾化装置碰撞，从而转变成水雾即可；其中，倒圆台结构或倒圆锥结构指竖直状态下，该结构上大下小。进一步的，旋转盘表面开口或者不开口，优选开口，作为示例，可以利用倒圆台结构或倒圆锥结构的侧边形成开口（底边为空），承接水并可将其射出。优选的，所述旋转盘的侧边为斜面结构，斜面结构与水平面的夹角优选为0～60度。以旋转盘为圆锥结构为例，旋转盘的半径与水平面之间的夹角为0～60度。
燃气热水器工作时，冷凝器产生的水由水输送结构流至旋转盘上，旋转盘优选为开口结构；第一驱动设备带动旋转盘转动，水被射出并与水雾化装置碰撞形成雾；雾从排烟管排出，完成燃气热水器的除水。
本发明中，水管的形状、结构不做具体限定，只要能够使得水在无需设置水输送动力设备的情况下自流至旋转盘上即可，从而减少能源利用，达到节能效果。冷凝器集水腔内的水通过水管输送至旋转盘上，电机驱动旋转盘转动，水随转动的旋转盘射出，与栅格碰撞，从而转变成水雾，无需设置气源、水泵等高能耗设备，仅利用旋转盘转动即可实现雾化功能，符合燃气热水器节能设计初衷，尤其是本发明旋转盘结合水雾化装置的机构对驱动设备的功率要求低，现有常规热水器的电源能够满足，无需额外设置电源。
下面结合附图及实施例二十六至实施例三十七对该技术方案作进一步描述，涉及的具体部件为现有产品，具体部件上设有常规的安装件，具体部件之间的连接、安装、使用方法为常规技术。本发明使用的驱动设备为电机（现有产品，27W），无需增加电源，常规燃气热水器的预留电源可以满足要求。
实验方法：在实验室条件下，分别取1.3L的水加入集水腔进行20分钟实验，仅启动热水器燃烧控制风扇、电机（最大转速），排烟管出口下方放小桶收集滴水；排烟管出口收集的水为滴水，是现有技术的问题之一，本发明旋转盘转动，水被射出并与水雾化装置碰撞形成雾，雾从排烟管排出，不仅具有较高的排放效率，而且排放过程雾化占比高，缓解了水滴滴水现象。雾化占比=（1-排烟管出口收集的水）/除去的水×100%；除去的水=1.3-集水腔剩余的水；以上水的单位为L。
实施例实验时，将排烟管出口斜向上15°，排烟管向上倾斜一定角度的严苛试验条件下，排水效率依然高，且避免了冷凝水滴在建筑外表面，造成对建筑物外表面腐蚀的现象。
