本申请提出一种采暖热水炉的控制方法。
在本申请实施例中，所述采暖热水炉包括流量分配器、采暖支路、供热支路以及卫浴流路，所述流量分配器具有连接采暖支路的采暖出口和连接供热支路的供热出口，所述卫浴流路用以与所述供热支路热交换。
如图1所示，所述采暖热水炉的控制方法包括以下步骤：
步骤S10，确定接收到卫浴用水信号，控制采暖出口关闭，供热出口打开。
该步骤S10中，卫浴用水信号指的是卫浴流路内有水流通的信号，即用户开始使用热水用于洗澡、洗手、洗碗或其它清洗等，例如，在一些情景中，卫浴流路被打开，水能够在卫浴流路内流通，视为接收到卫浴用水信号。在一些情景中，采暖热水炉具有预约卫浴用水功能，在到达预约时间时，采暖热水炉自动对卫浴用水进行加热，水开始在卫浴流路内流动，此时视为接收到卫浴用水信号，加热后的水能够流入储水罐内储存，待用户需要使用时可实现即时出热水。
在这一步骤中，接收到卫浴用水信号时表明用户存在使用热水用于卫浴的需求，故为能够快速获取到热水，此时控制采暖出口关闭，供热出口打开，由于热水不再分流到采暖支路用于室内采暖，所有的热水均流入供热支路，用于与卫浴用水进行热交换，从而可快速将卫浴用水加热。
可以想到的是，控制采暖出口关闭，供热出口打开实质上是控制流量分配器进行调节。
步骤S20，获取当前卫浴出口的水温。
卫浴流路具有卫浴入口和卫浴出口，卫浴入口与水源例如自来水接通，卫浴出口则连接花洒、出水龙头或是储水罐等，卫浴出口的水已经与供热支路实现了热交换，通过检测该卫浴出口的水温，能够获取到实际用水温度以及卫浴流路与供热支路的热交换情况。
步骤S30，获取卫浴出口的水温在预设水温范围内的持续时长。
流量分配器将采暖出口关闭，供热出口打开后，所有的热水均用于制取卫浴用的热水，但是从卫浴出口流出的热水的温度不一定满足用户需求，故此时需要对用户用水端的水温进行调节。具体而言，可通过调节卫浴出口的水温至预设的水温范围内，满足用户需求。具体地调节方式包括但不限于以下几种：调节采暖热水炉的热负荷，例如在采暖热水炉为燃气炉的情况下，调节燃烧器的燃气进气量；在采暖热水炉为电热水炉的情况下，调节加热模块的电功率。调节卫浴流路的流量，通过增大或减小卫浴流路的流量，使得卫浴出口的水温维持在预设水温范围内。在卫浴出口设置混水阀，混水阀上连接常温水管支路，通过混入常温水来调节卫浴出口的水温。
该步骤中的预设水温范围为控制器预先存储的温度值，通常由用户临时设定的值或是厂家根据不同用水模式提前设定的不同的值。在该范围内，用户能够忽略或接受温度的变化。在一些示例中，预设水温范围指的是一个较大的范围，例如在洗碗或清洗桌子、地面时，对水温的要求较低，预设水温范围指的是设定值的±5℃或±10℃等等。在一些示例中，预设水温范围指的是一个较小的范围，例如在用于洗澡或者婴幼儿用水时，这类用户对水温较为敏感，预设水温范围指的是设定值的±2℃，即保证当前卫浴出口的水温在设定值加上或减去2℃之间波动。
步骤S40，确定持续时长大于或等于第一预设时长，且采暖热水炉热负荷小于额定负荷，控制供热出口的开度减小，采暖出口的开度增大。
由于受采暖热水炉热负荷、换热效率、卫浴流路内的流速、供热支路的流速等等因素的影响，故卫浴出口的水温并不是一直维持在某一特定值不变的，故当卫浴出口的水温在预设水温范围内维持较长时间时，表明此时换热较为稳定，为避免室内温度持续下降，故此时需要控制流量分配器分配部分热水用于室内采暖。即确定持续时长大于或等于第一预设时长，且采暖热水炉热负荷小于额定负荷，控制供热出口的开度减小，采暖出口的开度增大，保证供热出口和采暖出口都是部分打开的。
步骤S50，控制采暖热水炉热负荷增大，维持卫浴出口的水温在预设水温范围内。
由于供热出口和采暖出口都是部分打开的，采暖的热水同时用于室内采暖和加热卫浴用水，为避免热水分流导致加热卫浴用水的热量不够，故控制采暖热水炉热负荷增大，维持卫浴出口的水温在预设水温范围内。
本申请中，当采暖热水炉从单采暖状态(即采暖热水炉产生的热水全部从采暖出口流动而全部用于室内采暖的状态)，切换至单加热卫浴用水状态(采暖热水炉产生的热水全 部从供热出口流动而用于加热卫浴用水的状态)后，只有维持卫浴出口的水温在预设水温范围内一段时间，保证卫浴出口的水温较为稳定以后，才控制流量分配器进行切换，使得采暖出口的开度增大，卫浴出口的开度则对应减小。并且在调节流量分配器的同时，即使在调节卫浴出口的开度导致用于加热卫浴用水的热水分流一部分给室内采暖，也能够通过增大采暖热水炉负荷，来将卫浴出口的水温维持在预设水温范围内，避免卫浴出口的水温产生过大的波动范围，从而保证用户用水的连续舒适性。
请结合参考图2，步骤S40具体包括：
步骤S41，确定持续时长大于或等于第一预设时长，且采暖热水炉热负荷小于额定负荷，控制流量分配器朝采暖出口逐次调节，以使供热出口的开度逐次减小，采暖出口的开度逐次增大。
若流量分配器将采暖出口和供热出口一次性调节到位，则采暖出口的开度瞬间增大很多，而供热出口的开度瞬间减小很多，供热支路内的热水流量一下子减小很多，导致卫浴出口的水温很容易低于预设水温范围，用户感受的水温瞬间降低很多。故为了避免此现象，该步骤S41中，采用将流量分配器进行逐次调节的方式，使得在每一次调节中，供热出口的开度减小的幅度较小，因此能缓解卫浴出口的水温的波动。
在一实施例中，第一预设时长大于或等于0.5分钟，且小于或等于3分钟，例如，第一预设时长可为0.5min、1min或3min等等。
步骤S50具体包括：
步骤S51，确定流量分配器朝采暖出口每调节一次，控制采暖热水炉热负荷增大一次，维持卫浴出口水温在预设水温范围内。
流量分配器朝采暖出口每调节一次，供热出口的开度必然是会减小一次的，每次流入供热出口的热水减少，用于与卫浴用水换热的热水减少，则卫浴出口的水温必然是会下降的，故而每调节一次流量分配器，都控制采暖热水炉的热负荷增大一次，对采暖热水炉的热负荷进行调节，维持卫浴出口水温在预设水温范围内，保证用水的舒适度。
本申请中，由于流量分配器是朝采暖出口逐次调节的，每次调节供热出口关闭的开度较小，故每次流入供热支路用于为卫浴用水制热的热水减小的幅度较小，因此卫浴出口的水温减小的程度较低，其在降低之后也仍然能够维持在预设水温范围，至少地在调节流量分配器之后的短时间内可以维持在预设水温范围内，满足用户用水的需求。而每调节一次流量分配器，均调节一次采暖热水炉的热负荷，使得卫浴出口的水温升高，并稳定在预设水温范围内，从而可以避免卫浴出口的水温跌出预设水温的范围，保证用户用水的连续舒适性。
步骤S52，确定采暖热水炉热负荷达到额定负荷，停止流量分配器的调节。
在反复调节采暖热水炉的热负荷的过程中，当采暖热水炉热负荷达到额定负荷，则停止流量分配器的调节，采暖热水炉以额定负荷的状态工作，卫浴出口的水温维持在预设水温范围内，室内采暖同样有热水作用，该采暖热水炉同时进行室内采暖和提供卫浴用水。
所述采暖热水炉还包括与所述流量分配器连接的电机；
一实施例中，所述电机为同步电机，所述流量分配器朝采暖出口每调节一次，对应的同步电机的通电时长为t/n；其中，t为同步电机驱动流量分配器在采暖出口与供热出口之间完全切换所需的通电时长。n为常数，
一实施例中，所述电机为步进电机，所述流量分配器朝采暖出口每调节一次，对应的朝步进电机发送的脉冲个数为N/n；其中，N为步进电机驱动流量分配器在采暖出口与供热出口之间完全切换所需的脉冲个数，n为常数。
在一实施例中，n大于或等于10且小于或等于20。具体而言，n的取值可为10、12、15或20等，n的取值不同，供热出口每次减小的开度是不同的。
请结合参考图3，步骤S52确定采暖热水炉热负荷达到额定负荷，停止流量分配器的调节之后还包括：
步骤S61，确定卫浴出口的水温低于预设水温范围，控制供热出口增大预设开度，采 暖出口减小预设开度。
由于受到水流流速、自来水温度、换热效率、工作时长等因素的影响，在采暖热水炉工作较长时间后，卫浴出口的水温有可能会产生波动，即存在低于预设水温范围的情况，在这种情况下，采暖出口和供热出口均打开，采暖热水炉的热负荷达到额定负荷，故无法通过增大采暖热水炉热负荷的形式来增大卫浴出口的水温，因此控制供热出口增大预设开度，采暖出口减小预设开度，使得流经供热支路的热水增加，从而提高与卫浴用水的换热效率，使得卫浴出口的水温增大，再次维持卫浴出口的水温在预设水温范围。
步骤S62，调节采暖热水炉的热负荷，维持卫浴出口的水温在预设水温范围。
由于流经供热支路的热水增加，供热支路与卫浴流路之间的换热情况必然是发生改变的，因此需要调节采暖热水炉的热负荷，维持卫浴出口的水温在预设水温范围。
请结合参考图4，步骤S61确定卫浴出口的水温低于预设水温范围，控制供热出口增大预设开度，采暖出口减小预设开度具体包括以下步骤：
步骤S611，获取流量分配器朝采暖出口的调节次数A；
步骤S612，确定卫浴出口的水温在预设水温范围，获取卫浴流路的流量q 1；
步骤S613，确定卫浴出口的水温低于预设水温范围，获取卫浴流路的流量q 2；
步骤S614，根据A、q 1以及q 2计算预设开度；
步骤S615，控制供热出口增大预设开度，采暖出口减小预设开度。
其中，调节次数A表明了卫浴出口的水温发生较大波动之前供热出口的初始开度，因此当卫浴出口的水温产生较大波动之后，供热出口增大的预设开度是与初始开度相关的，两者的叠加必然需要小于或等于供热出口的完整开度。
当卫浴流路的流量突然间增大时，卫浴出口的水温必然会发生改变，即当其低于预设水温范围，需要获取此时的位于流路的流量q 2，流量q 2和流量q 1表明了相当于是改变之后卫浴出口的水温和改变之前卫浴出口的水温。
一般可认为当卫浴出口的水温低于预设水温范围的最低值的2℃时，卫浴流路的流量是增大的，此时才需要对供热出口的开度进行调节，以使其增大预设开度。
本实施例中，确定卫浴出口的水温低于预设水温范围，需要对供热出口的开度进行调节时，其具体地调节开度是由流量分配器朝采暖出口的调节次数A、卫浴出口的水温在预设范围时卫浴流路的流量q 1、卫浴出口的水温低于预设范围时卫浴流路的流量q 2计算得出的，即改变的预设开度与供热出口当前的开度、卫浴出口改变之前和改变之后的水温息息相关。
在一实施例中，所述电机为同步电机，所述预设开度所对应的同步电机的通电时长为Bt/n。即确定卫浴出口的水温低于预设水温范围，控制同步电机的通电时长为Bt/n，以使供热出口增大预设开度，采暖出口减小预设开度。
一实施例中，所述电机为步进电机，所述预设开度所对应的朝步进电机发送的脉冲个数为BN/n。即确定卫浴出口的水温低于预设水温范围，控制朝步进电机发送的脉冲个数为BN/n，以使供热出口增大预设开度，采暖出口减小预设开度。其中B根据A、q 1以及q 2计算得出。
在一实施例中，所述B与A、q 1以及q 2之间的关系为：B＝(q 2-q 1)(n-A)/q 1。具体地，预设开度与前后两次流量的差值呈正比，前后两次流量的差值表明前后两次的温差，温差越大，表明卫浴出口的水温下降越大，故需要更大的预设开度，使得供热出口的开度更大，以使更多的热水作用于加热卫浴用水，以便卫浴出口的水温快速上升。
请结合参考图5，所述采暖热水炉的控制方法还包括以下步骤：
步骤S71，获取停止采暖指令；
步骤S72，确定采暖出口和供热出口均打开，控制采暖出口关闭，供热出口完全打开；
步骤S73，调节采暖热水炉的热负荷，维持卫浴出口的水温在预设水温范围。
本实施例中，当采暖热水炉处于同时采暖和加热卫浴用水状态时，由于室内温度过高发出停止采暖指令时，此时控制采暖出口关闭，供热出口完全打开，使得所有的热水均用 于加热卫浴流路内的卫浴用水，同时调节采暖热水炉的热负荷，维持卫浴出口的水温在预设水温范围。
请结合参考图6，步骤S72确定采暖出口和供热出口均打开，控制采暖出口关闭，供热出口完全打开具体包括：
步骤S721，确定采暖出口和供热出口均打开，控制流量分配器朝供热出口逐次调节，以使供热出口的开度逐次增大，采暖出口的开度逐次减小。
步骤S73调节采暖热水炉的热负荷，维持卫浴出口的水温在预设水温范围具体包括：
步骤S731，确定流量分配器朝供热出口每调节一次，控制采暖热水炉的热负荷减小一次，维持卫浴出口的水温在预设水温范围；
步骤S732，确定采暖出口关闭，供热出口完全打开，停止流量分配器的调节。
同样地，在该实施例中，由于流量分配器是朝供热出口逐次调节的，每次增大供热出口的开度较小，故每次流入供热支路用于为卫浴用水制热的热水增加的幅度较小，因此卫浴出口的水温增大的程度较小，其在增大之后也仍然能够维持在预设水温范围，至少地在调节流量分配器之后的短时间内可以维持在预设水温范围内，满足用户用水的需求。而每调节一次流量分配器，均调节一次采暖热水炉的热负荷，使得卫浴出口的水温减小，并稳定在预设水温范围内，从而可以避免卫浴出口的水温超出预设水温的范围，保证用户用水的连续舒适性。

在本申请实施例中，如图8至图13所示，为本申请采暖热水炉另一实施例的结构示意图，所述采暖热水炉包括：

具体地，所述采暖热水装置通常还包括外壳90，所述采暖热水炉还包括外壳90，所述第一换热器10和所述流量分配器50设置在所述外壳90内。所述流量分配器50与所述外壳90的底壁固定。在一实施例中，流量分配器50与外壳90通过螺钉或采用焊接或卡扣的方式进行固定。该实施例中，连接在流量分配器50采暖分流口102的管路朝下贯穿外壳90的底壁而与采暖出水口21连接。
具体地，所述采暖系统通常还包括对第一换热器10进行加热的加热单元。其中，加热单元可以为不同种类的加热装置，例如，加热单元可以为燃烧器，其通过对可燃气体进行燃烧进而对流经第一换热器10的液体(例如水等)进行加热；加热单元也可以是电加热装置，例如电阻丝、电加热棒等，通过电加热的方式对流经第一换热器10的液体(例如水等)进行加热；加热单元还可以为冷凝器，通过冷凝器对流经第一换热器10的液体(例如水等)进行加热；当然，加热单元包含的种类不限于上述描述，其它任何可以对流经第一换热器10中的液体(例如水等，下文以水为例进行说明)进行加热的加热单元均可以在本实施方式中使用。
具体地，所述采暖热水系统通常还包括连接于采暖出水口21与采暖回水口22之间的采暖装置(如暖气片或地暖管路等)(图未示)，所述采暖装置流出的液体(如水等)经过采暖回水口22流入第一换热器10，该液体在被第一换热器10加热后，又从采暖出水口21流入采暖装置内。具体地，所述采暖回水口22与第一换热器10的入口连通，所述采暖出水口21与第一换热器10的出口连通。
卫浴水(包括但不限于生活用水/卫浴用水，比如也可以为实验室用水等)可从第一入口41并经由卫浴入口104进入流量分配器50内，并从卫浴出口105流出流量分配器50，而流向第一出口42。卫浴水在卫浴流路内与加热流路内的热水换热，以获得加热后的卫浴水。
具体说来，所述热水系统还包括第二换热器80，第二换热器80为板式换热器，所述第二换热器80具有第一流道和第二流道，所述第一流道构成所述加热流路的一部分，所述第二流道构成所述卫浴流路的一部分。工作时，卫浴水通过第一入口41进入第二流道内，同时，第一换热器10流出的热水经由热水分流口103进入第一流道内，第一流道内的热水会与第二流道内的卫浴水换热，以实现对卫浴水加热；换热后，第一流道内的水流回第一换热器10，第二流道内的被加热后的卫浴水经由流量分配器50的卫浴入口104和卫浴出口105而流向第一出口42。
此外，其它实施例中，第二换热器80还可为管式换热器，第一流道和第二流道呈同轴且内外设置。
所述第一阀芯11设置在所述热水进口101、采暖分流口102与热水分流口103之间指 的是，第一阀芯11能够控制所述热水进口101与采暖分流口102之间的通断，且第一阀芯11还能够控制所述热水进口101与热水分流口103之间的通断。
具体地，一实施例中，所述流量分配器50具有连通所述热水进口101与所述采暖分流口102的单采暖工况，在该单采暖工况下，第一阀芯11将热水进口101和热水分流口103之间断开，第一换热器10流出的所有热水全部用于室内采暖。具体来说，当所述流量分配器50处于单采暖工况时，热水进口101与采暖分流口102连通，第一换热器10加热的热水通过流量分配器50(的热水进口101与采暖分流口102)流向采暖出水口21，以实现采暖热水炉供暖。
在一实施例中，所述流量分配器50还具有连通所述热水进口101与所述热水分流口103的单加热工况，在该单加热工况下，第一阀芯11将热水进口101和采暖分流口102之间断开，第一换热器10流出的所有热水全部用于加热卫浴水。当所述流量分配器50处于单加热工况时，热水进口101与热水分流口103连通，第一换热器10加热的热水通过流量分配器50(的热水进口101与热水分流口103)流向第一流道，以与第二流道内的卫浴水换热，即实现对卫浴热水加热以得到卫浴热水，从而实现采暖热水炉提供卫浴热水(即加热的卫浴水)。
在一实施例中，所述流量分配器50还具有同时连通所述热水进口101与所述采暖分流口102和所述热水分流口103的采暖加热混合工况。在该采暖加热混合工况下，热水进口101与所述采暖分流口102连通，且热水进口101还和所述热水分流口103连通。并且在该混合工况下，第一阀芯11能够调节采暖分流口102和热水分流口103的开度，例如，第一阀芯11朝采暖分流口102移动时，采暖分流口102的开度减小，热水分流口103的开度相应增大；同样的，第一阀芯11朝热水分流口103移动时，热水分流口103的开度减小，采暖分流口102的开度相应增大。当所述流量分配器50处于混合工况时，热水进口101同时与采暖分流口102和热水分流口103连通，如图所示，第一换热器10加热的热水一部分通过流量分配器50(的热水进口101与采暖分流口102)流向采暖出水口21，以实现采暖热水炉供暖；同时，第一换热器10加热的热水一部分通过流量分配器50(的热水进口101与热水分流口103)流向第一流道，以与第二流道内的卫浴水换热，即实现对卫浴热水加热以得到卫浴热水，从而实现采暖热水炉提供卫浴热水。
即是说，当所述流量分配器50处于混合工况时，采暖热水炉可实现供暖和提供卫浴热水同时进行(即采暖热水炉可满足在提供采暖的同时，可对卫浴水进行加热)，以提高用户使用舒适度。
所以，采暖热水炉可实现单独供暖，也可实现单独提供卫浴热水，还可实现供暖和提供卫浴热水同时进行(即采暖热水炉可满足在供暖的同时，也可对卫浴水进行加热)，以提高用户使用舒适度，从而使得采暖热水炉功能多样化。
所述第二阀芯设置在所述卫浴入口104和所述卫浴出口105之间，指的是所述第二阀芯能够控制所述卫浴入口104和所述卫浴出口105之间的通断。
在本申请中，流量分配器50为一个整体结构，在其内部加工出多个连通流道，将热水进口101、采暖分流口102和热水分流口103相应连接，并将卫浴入口104和卫浴出口105相应连接。采暖系统以及热水系统中的加热流路和卫浴流路均共同连接在一个流量分配器50上，流量分配器50既可控制从第一换热器10流出的热水的分流，又能够控制卫浴水的通断，该流量分配器50集成了三通以及二通两个不同阀的功能，而不需要针对每一流路单独设置一个独立的开关阀，相对于单独设置一个三通阀和一个二通阀，或者是单独设置三个二通阀的形式而言，本实施例中的流量分配器50的结构更加紧凑，有利于减少对整机空间的占用。
具体地，所述热水系统还包括卫浴水循环泵43，所述卫浴水循环泵43用于驱动卫浴水从第一入口41经第二流道流向第一出口42。在一实施例中，所述卫浴水循环泵43可设于第一入口41与卫浴入口104之间的管路或第一出口42与卫浴出口105之间的管路。
进一步地，所述第一入口41设有第一温度传感器44；和/或，所述第一出口42设有 第二温度传感器45。
具体地，所述第一温度传感器44用于检测第一入口41的进水温度/回水温度，所述第二温度传感器45用于检测第一出口42的出水温度，以调节流量分配器50的工况，如此可更为准确的对卫浴水的温度进行控制，防止可能出现的温度过高或过低的问题。
在本申请的更进一步的实施例中，所述热水系统还包括储水罐46；当然，于其他实施例中，也可不设置储水罐46。以下结合储水罐46对热水系统和采暖热水炉进行详细说明。
具体地，所述储水罐46连接于第一出口42与第二流道之间，所述储水罐46用于储存第二流道内送出的卫浴热水。其中，所述储水罐46连接于第一出口42与第二流道的出口之间。
请结合参考图8，所述卫浴流路包括第一卫浴水管路47、第二卫浴水管路48和第三卫浴水管路49，所述第一卫浴水管路47连通储水罐46的入水口与流量分配器50的卫浴出口105，所述第二卫浴水管路48连通储水罐46的出水口与第一出口42。第三卫浴水管路49分别连接第一入口41和第二流道的进水口，而第二流道则将第一卫浴水管路47和第三卫浴水管路49连接。如此，从第三卫浴水管路49进入的卫浴水在第二流道加热后形成卫浴热水，卫浴热水可通过第一卫浴水管路47流入储水罐46内；然后又可通过第二卫浴水管路48从储水罐46内流向第一出口42。
如此，第二流道送出的卫浴热水在进入储水罐46内后，会与储水罐46内存储的卫浴热水混合(可以理解，混合后的卫浴热水的水温相对较稳定)，然后混合后的卫浴热水流向第一出口42；从而可避免经第二换热器80加热后的卫浴热水直接送到第一出口42，以避免第一出口42流出的卫浴热水的水温波动较大，从而可提高采暖热水炉提供的卫浴热水的水温的稳定性。
可以理解，为了减小外壳90的竖向尺寸，通常将所述储水罐46设于第一换热器10和第二换热器80的一侧(如图中的左侧或右侧)。
在一实施例中，所述流量分配器50设置在所述第二流道的出水端，如此流量分配器50也是邻近第一流道设置的，从而利于流量分配器50同时连接第一流道和第二流道。在设置有储水罐46的实施例中，流量分配器50设置在第一卫浴水管路47，避免储水罐46内的水回流到第二流道。
在一实施例中，所述卫浴出口105的开口方向沿横向，如此与卫浴出口105连接的管路，例如一些实施例中指的是第一卫浴水管路47，能够沿横向延伸出去，并且在储水罐46位于流量分配器50的上方时，第一卫浴水管路47仅需要朝上折弯一次且折弯角度为90°即可，相对于将卫浴出口105的开口方向朝下设置，第一卫浴水管路47需要先朝横向折弯再朝上折弯的方式，本实施例中，卫浴出口105的开口朝横向，能够减少第一卫浴水管路47的折弯次数和角度，能够方便第一卫浴水管路47的设置。
第一阀芯11、热水进口101、采暖分流口102和热水分流口103类似于形成三通阀的结构，而第二阀芯、卫浴入口104和卫浴出口105类似于形成二通阀的结构，本申请中将三通阀和二通阀两个阀结合形成一体结构，既使得两者之间结构紧凑，又使得两者之间不需要再额外进行组装，减少了安装步骤。
具体而言，在一实施例中，卫浴入口104和卫浴出口105共同设置在所述热水进口101、所述采暖分流口102和所述热水分流口103的同一侧，例如，卫浴入口104和卫浴出口105共同设置在所述热水进口101、所述采暖分流口102和所述热水分流口103的左侧或右侧，即三通阀和二通阀沿左右向布置，使得组成同一个阀的部分集中设置在一侧，结构更为紧凑。
所述热水进口101、所述采暖分流口102、所述热水分流口103和所述卫浴出口105分设于所述流量分配器50的不同表面，所述热水分流口103和所述卫浴入口104设置在所述流量分配器50的同一侧。在一实施例中，所述热水进口101设置在所述流量分配器的左侧，所述采暖分流口102设置在所述流量分配器的底部，所述热水分流口103和所述卫浴入口104设置在所述流量分配器的后侧，所述卫浴出口105设置在所述流量分配器的 右侧。如此设置之后，使得所述热水分流口103和所述卫浴入口104设置在所述流量分配器50的同一侧，由于两者均是连接第二换热器80的，因此两者在同一侧的结构更加紧凑，能够减少管路的弯折。而所述热水进口101、所述采暖分流口102、所述热水分流口103和所述卫浴出口105分设于所述流量分配器50的不同表面，使得连接不同位置的管路朝不同方向延伸，可以避免各个管路之间交错。
所述流量分配器50还具有备用出水孔106，所述备用出水孔106连通所述卫浴入口104和所述卫浴出口105。则从第二流道流入到流量分配器50内的卫浴水既可以流向卫浴出口105，又可以流向备用出水孔106。所述流量分配器50还包括封堵件12，所述封堵件12封堵所述备用出水孔106，如此从第二流到流入流量分配器50的卫浴水仅能够流向卫浴出口105，然而在需要使用备用出水孔106时，仅需要取下封堵件12即可，从而可提高使用的灵活性。
请结合参考图13，所述流量分配器50内设置有采暖分流流道13、加热分流流道14和采暖出水流道15，所述采暖分流流道13和所述加热分流流道14分别连接所述热水进口101，所述加热分流流道14的管壁设置有所述热水分流口103。所述采暖分流流道13的管壁设有贯穿所述流量分配器50的第一开口131，所述采暖出水流道15贯穿所述流量分配器50的其中一表面而形成所述采暖分流口102，所述采暖出水流道15的管壁开设有贯穿所述流量分配器50的第二开口151，所述第一开口131和所述第二开口151之间通过旁通管路16(如图11所示)连接。具体地，从第一换热器10流出的热水流入流量分配器50的热水进口101，在混合工况下，热水分成两路，一路流向采暖分流流道13，另一路流向加热分流流道14，采暖分流流道13内的热水则从第一开口131流向旁通管路16，并从第二开口151流向采暖出水流道15，接着从采暖分流口102流向采暖出水口21，并最终从采暖回水口22回流至第一换热器10。加热分流流道14内的热水则从热水分流口103流向第二换热器80的第一流道，并在与卫浴水换热后回流至第一换热器10。图13中的虚线箭头代表水流方向。
上述中，通过设置旁通管路16后，可实现第一开口131和第二开口151的连通，方便各个流道的加工。
所述采暖热水炉还包括存储器、处理器及存储在所述存储器上并可在所述处理器上运行的计算机程序，所述计算机程序被所述处理器执行时实现如上所述的方法的步骤。
本申请还提出一种计算机可读存储介质，所述计算机可读存储介质上存储有采暖热水炉处理程序，所述采暖热水炉处理程序被控制器执行时实现如上所述的采暖热水炉的控制方法的步骤。
以上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，凡是在本申请的申请构思下，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。
