Description

排烟组件及燃气热水器
技术领域
本申请涉及热水器领域，更具体而言，涉及一种排烟组件，以及一种具有上述排烟组件的燃气热水器。
背景技术
燃气热水器一般通过相连接的排烟罩和排气管排烟，而现有燃气热水器的排烟罩和排气管是两个独立的零件，在热水器生产装配时，需要工人将排烟罩和排烟管安装固定在一起，导致现有燃气热水器产品的装配工序较为复杂，从而导致产品生产效率较低。
申请内容
本申请旨在解决现有技术中存在的技术问题至少之一。
为此，本申请的一个目的在于，提供一种可提升燃气热水器生产效率的排烟组件。
本申请的另一个目的在于，提供一种燃气热水器，包括上述排烟组件。
为实现上述目的，本申请第一方面的实施例提供了一种排烟组件，用燃气燃气热水器，所述排烟组件包括排烟罩，所述排烟罩上设有排烟管，所述排烟管与所述排烟罩一体成型。
本方案中，排烟管与排烟罩一体成型，这样设计省去了排烟管与排烟罩的装配工作，简化了燃气热水器产品的装配工序，从而可提升燃气热水器产品的生产效率。
在上述任一技术方案中，可选地，所述排烟管与所述排烟罩一体注塑成型。
本方案中，排烟管和排烟罩的生产材料采用塑胶材料，排烟管与排烟罩一体注塑成型，这样设计排烟组件的生产工艺简单，且排烟组件的生产成本低。
在上述任一技术方案中，可选地，所述排烟罩内形成空腔，所述空腔的底端敞开，所述排烟管设置在所述排烟罩的顶端并与所述空腔相连通。
在上述任一技术方案中，可选地，所述排烟组件还包括冷凝水收集盒，所述排烟罩安装在所述冷凝水收集盒的顶部。
本方案提供的排烟组件还包括冷凝水收集盒，排烟罩和燃气热水器的换热器安装在冷凝水收集盒的顶部，空气和燃气的混合气体燃烧后所形成的烟气先进入换热器内，烟气与换热器换热后温度降低并产生一定冷凝水，然后烟气和冷凝水由换热器的出风口进入冷凝水收集盒，接着冷凝水由冷凝水收集盒底部的排水口排出，而烟气会由冷凝水收集盒进入排烟罩内，随后由排烟罩进入排烟管，再由排烟管排出。
在上述任一技术方案中，可选地，所述冷凝水收集盒包括盒体底壁和由所述盒体底壁的边缘向上延伸的盒体侧壁，所述冷凝水收集盒的顶部形成盒口，所述排烟罩的底端与所述盒体侧壁的顶端相连接。

在上述任一技术方案中，可选地，所述排烟罩的底端和所述盒体侧壁的顶端通过螺钉连接。
本方案中，排烟罩通过螺钉安装在冷凝水收集盒上，这样设计排烟罩与冷凝水收集盒连接固定的可靠性高，排烟罩和冷凝水收集盒不容易出现松动问题。具体地，排烟罩底端和盒体侧壁顶端中的一个上设有螺柱、另一个上设有连接孔，排烟罩安装到冷凝水收集盒上时，螺柱与连接孔对齐并通过螺钉固定。
在上述任一技术方案中，可选地，所述盒体底壁上设有支撑部，所述支撑部包括螺柱和支撑凸起，所述排烟罩底端靠近所述支撑部的一侧设有凸筋，所述凸筋上设有通孔，所述凸筋与所述支撑凸起的顶部抵触，且所述通孔与所述螺柱相对，所述燃气热水器的换热器通过螺钉与所述螺柱相连接，并将所述凸筋压紧固定在所述支撑凸起上。
现有技术中，排烟罩和换热器安装在冷凝水收集盒的顶端，使排烟罩、换热器与冷凝水收集盒连通，排烟罩、换热器与盒体侧壁对应的位置分别通过螺钉与盒体侧壁固定连接，且需要在盒体底壁上为排烟罩和换热器分别设置螺柱，以使排烟罩、换热器位于盒体底壁上的部位分别通过螺钉与螺柱固定连接，但采用这种固定方式打螺钉的数量过多，导致燃气热水器产品的生产装配效率低。本方案改变了排烟罩的固定方式，在盒体底壁上设置一个支撑凸起和一个螺柱，并在排烟罩靠近螺柱的一侧设置凸筋，排烟罩、换热器、冷凝水收集盒三者相装配时，先将排烟罩安装到冷凝水收集盒上，排烟罩与盒体侧壁对应的位置通过螺钉与盒体侧壁固定连接，排烟罩的凸筋与盒体底壁上的支撑凸起抵触，且凸筋上的通孔与螺柱对齐，排烟罩到位后，再将换热器安装到冷凝水收集盒上，换热器与盒体侧壁对应的位置通过螺钉与盒体侧壁固定连接，换热器位于盒体底壁上方的部分通过螺钉与螺柱相连接，并将凸筋压紧固定在所述支撑凸起上，从而完成排烟罩、换热器、冷凝水收集盒三者的装配工作，这样设计减少了打螺钉的数量，从而可提升燃气热水器产品的生产装配效率低。
在上述任一技术方案中，可选地，所述盒体侧壁的顶端设有向外延伸的翻边，所述排烟罩的底端通螺钉与所述翻边相连接。
本方案在盒体侧壁的顶部设置翻边，排烟罩与冷凝水收集盒的翻边通过螺钉连接，这样设计可提升排烟罩与冷凝水收集盒连接固定的可靠性。

本申请第三方面的实施例提供了一种燃气热水器，包括本申请第一方面任一实施例提供的排烟组件。
本申请第三方面实施例提供的燃气热水器，具有本申请第一方面任一实施例提供的排烟组件，因此该燃气热水器具有上述任一实施例提供的排烟组件的全部有益效果，在此不再赘述。

1排烟罩，11排烟管，12凸筋，2冷凝水收集盒，21盒体底壁，211螺柱，212支撑凸起，213排水口，22盒体侧壁，221翻边，3风机，4燃烧器，5换热器。
本申请目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请的一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
需要说明，若本申请实施例中有涉及方向性指示（诸如上、下、左、右、前、后……），则该方向性指示仅设置为解释在某一特定姿态（如附图所示）下各部件之间的相对位置关系、运动情况等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。
另外，若本申请实施例中有涉及“第一”、“第二”等的描述，则该“第一”、“第二”等的描述仅设置为描述目的，而不能理解为指示或暗示其相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。另外，各个实施例之间的技术方案可以相互结合，但是必须是以本领域普通技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应当认为这种技术方案的结合不存在，也不在本申请要求的保护范围之内。
本申请第一方面的实施例提供了一种用燃气燃气热水器的排烟组件，如图1至图11所示，排烟组件包括排烟罩1，排烟罩1上设有排烟管11，排烟管11与排烟罩1一体成型。
本方案中，排烟管11与排烟罩1一体成型，这样设计省去了排烟管11与排烟罩1的装配工作，简化了燃气热水器产品的装配工序，从而可提升燃气热水器产品的生产效率。
在上述任一技术方案中，可选地，排烟管11与排烟罩1一体注塑成型。
本方案中，排烟管11和排烟罩1的生产材料采用塑胶材料，排烟管11与排烟罩1一体注塑成型，这样设计排烟组件的生产工艺简单，且排烟组件的生产成本低。
在上述任一技术方案中，可选地，排烟罩1内形成空腔，空腔的底端敞开，排烟管11设置在排烟罩1的顶端并与空腔相连通。
在上述任一技术方案中，可选地，排烟组件还包括冷凝水收集盒2，排烟罩1安装在冷凝水收集盒2的顶部。
本方案提供的排烟组件还包括冷凝水收集盒2，排烟罩1和燃气热水器的换热器5安装在冷凝水收集盒2的顶部，空气和燃气的混合气体燃烧后所形成的烟气先进入换热器5内，烟气与换热器5换热后温度降低并产生一定冷凝水，然后烟气和冷凝水由换热器5的出风口进入冷凝水收集盒2，接着冷凝水由冷凝水收集盒2底部的排水口213排出，而烟气会由冷凝水收集盒2进入排烟罩1内，随后由排烟罩1进入排烟管11，再由排烟管11排出。
在上述任一技术方案中，可选地，冷凝水收集盒2包括盒体底壁21和由盒体底壁21的边缘向上延伸的盒体侧壁22，冷凝水收集盒2的顶部形成盒口，排烟罩1的底端与盒体侧壁22的顶端相连接。
本方案中，冷凝水收集盒2为顶部敞开的盒体，这样设计冷凝水收集盒2 的结构简单，生产加工难度低。
在上述任一技术方案中，可选地，盒体侧壁22的顶端设有向外延伸的翻边221，排烟罩1的底端通螺钉与翻边221相连接。
本方案中，排烟罩1通过螺钉安装在冷凝水收集盒2上，这样设计排烟罩1与冷凝水收集盒2连接固定的可靠性高，排烟罩1和冷凝水收集盒2不容易出现松动问题。具体地，排烟罩底端和翻边中的一个上设有螺柱、另一个上设有连接孔，排烟罩安装到冷凝水收集盒上时，螺柱与连接孔对齐并通过螺钉固定。
如图3至图11所示，在上述任一技术方案中，可选地，盒体底壁21上设有支撑部，支撑部包括螺柱211和支撑凸起212，排烟罩1底端靠近支撑部的一侧设有凸筋12，凸筋12上设有通孔，凸筋12与支撑凸起212的顶部抵触，且通孔与螺柱211相对，燃气热水器的换热器5通过螺钉与螺柱211相连接，并将凸筋12压紧固定在支撑凸起212上。
现有技术中，排烟罩和换热器安装在冷凝水收集盒的顶端，使排烟罩、换热器与冷凝水收集盒连通，排烟罩、换热器与盒体侧壁对应的位置分别通过螺钉与盒体侧壁固定连接，且需要在盒体底壁上为排烟罩和换热器分别设置螺柱，以使排烟罩、换热器位于盒体底壁上的部位分别通过螺钉与螺柱固定连接，但采用这种固定方式打螺钉的数量过多，导致燃气热水器产品的生产装配效率低。本方案改变了排烟罩1的固定方式，在盒体底壁21上设置一个支撑凸起212和一个螺柱211，并在排烟罩1靠近螺柱211的一侧设置凸筋12，排烟罩1、换热器5、冷凝水收集盒2三者相装配时，先将排烟罩1安装到冷凝水收集盒2上，排烟罩1与盒体侧壁22对应的位置通过螺钉与盒体侧壁22固定连接，排烟罩1的凸筋12与盒体底壁21上的支撑凸起212抵触，且凸筋12上的通孔与螺柱211对齐，排烟罩1到位后，再将换热器5安装到冷凝水收集盒2上，换热器5与盒体侧壁22对应的位置通过螺钉与盒体侧壁22固定连接，换热器5位于盒体底壁21上方的部分通过螺钉与螺柱211相连接，并将凸筋12压紧固定在支撑凸起212上，从而完成排烟罩1、换热器5、冷凝水收集盒2三者的装配工作，这样设计减少了打螺钉的数量，从而可提升燃气热水器产品的生产装配效率低。
本申请第二方面的实施例提供了一种燃气热水器，包括本申请第一方面任一实施例提供的排烟组件。
本申请第二方面实施例提供的燃气热水器，具有本申请第一方面任一实施例提供的排烟组件，因此该燃气热水器具有上述任一实施例提供的排烟组件的全部有益效果，在此不再赘述。
本申请的一个实施例提供了一种全预混冷凝式燃气热水器，如图9至图11所示，该全预混冷凝式燃气热水器包括风机3、燃烧器4、换热器5和本申请第一方面任一实施例提供的排烟组件，风机3的出风口与燃烧器4的进风口相连接，燃烧器4的出风口与换热器5的进风口相连接，换热器5的出风口与排烟组件的进风口相连接。
其中可选地，燃气热水器的换热器是由显热换热器和潜热换热器组成的一体型冷凝式换热器，显热换热器直接使用燃烧器内气体燃烧所产生的热量来加热水，而潜热换热器是通过与气体燃烧产生的烟气进行热交换，通过烟气的热量来加热水。
在本申请的描述中，术语“顶”、“底”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制；术语“连接”、“安装”、“固定”等均应做广义理解，例如，“连接”可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是直接相连，也可以通过中间媒介间接相连。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。
在本说明书的描述中，参考术语“一个实施方式”、“某些实施方式”、“示意性实施方式”、“示例”、“具体示例”、或“一些示例”等的描述意指结合所述实施方式或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施方式或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施方式或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施方式或示例中以合适的方式结合。
以上所述仅为本申请的优选实施例，并非因此限制本申请的专利范围，凡是在本申请的发明构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
