冷藏冷冻装置 技术领域
本发明涉及制冷，特别是涉及冷藏冷冻装置。
背景技术
冷藏冷冻装置，例如冰箱、冰柜及冷藏柜等，利用制冷系统制冷。在制冷系统运行时，由于蒸发器的表面温度较低，容易产生凝露或凝霜。蒸发器上产生的凝露会直接流入接水盘内。至于凝霜，当蒸发器进入化霜状态时，则会融化并流入接水盘内。随着使用时间的延长，接水盘内往往会产生较多积水。
如何处理接水盘内的积水，成为本领域技术人员亟待解决的技术问题。现有技术中的部分冷藏冷冻装置，一般采用将接水盘安装于压机仓的方式来处理接水盘内的积水，这会导致压机仓的安装结构复杂。

可选地，制冷组件还包括冷凝器，设置于制冷回路内，且连接至压缩机的排气口；制冷系统还包括第一切换阀，连接至压缩机的排气口，且其具有连通冷凝器的阀口、以及连通旁通加热管的阀口；第一切换阀用于在旁通化霜管加热蒸发器时打开连通旁通加热管的阀口且关闭连通冷凝器的阀口。

根据下文结合附图对本发明具体实施例的详细描述，本领域技术人员将会更加明了本发明的上述以及其他目的、优点和特征。
附图说明
后文将参照附图以示例性而非限制性的方式详细描述本发明的一些具体实施例。附图中相同的附图标记标示了相同或类似的部件或部分。本领域技术人员应该理解，这些附图未必是按比例绘制的。附图中：
图1是根据本发明一个实施例的冷藏冷冻装置的示意性框图；
图2是根据本发明一个实施例的冷藏冷冻装置的示意性结构图；
图3是根据本发明一个实施例的用于冷藏冷冻装置的制冷系统的示意性框图；
图4是根据本发明一个实施例的用于冷藏冷冻装置的制冷系统的示意性结构图。
具体实施方式
图1是根据本发明一个实施例的冷藏冷冻装置10的示意性框图。冷藏冷冻装置10一般性地可包括箱体100、接水盘500和制冷系统200。
接水盘500设置于箱体100内，用于盛装制冷系统200运行时产生的冷凝水，例如，接水盘500可以设置于制冷系统200的蒸发器212下方，以便于蒸发器212上产生的冷凝水流入其中。
箱体100的内部形成有储物间室110。储物间室110可以为一个。该储物间室110的温区可以根据实际需要进行设置，例如该储物间室110可以为冷藏间室、冷冻间室、深冷间室或者变温间室中的任意一个。
图2是根据本发明一个实施例的冷藏冷冻装置10的示意性结构图。
在一些可选的实施例中，储物间室110可以为多个，例如两个。下述制冷系统200的蒸发器212所提供的冷量可以供给同一储物间室110，例如冷冻间室。在一些可选的实施例中，在向同一储物间室110供冷的情况下，下述制冷系统200的蒸发器212所提供的冷量还可以通过送风风道输送至其他储物间室110，例如冷藏间室，以实现多个储物间室110之间的冷量共享。在又一些可选的实施例中，每个蒸发器212对应一个储物间室110，每一蒸发器212既可以向各自对应的储物间室110供冷，也可以在一个蒸发器212化霜时，利用另一蒸发器212同时向两个储物间室110供冷。
图3是根据本发明一个实施例的用于冷藏冷冻装置的制冷系统的示意性框图。
制冷系统200一般性地可包括制冷组件210和旁通组件220。制冷组件210用于形成制冷回路。在无蒸发器212化霜的情况下，制冷系统200仅利用制冷回路使蒸发器212供冷。旁通组件220连接至制冷回路，例如可以附接至制冷回路，以形成旁通支路。制冷回路和旁通支路均可以流通制冷剂。制冷系统200通过调节制冷剂在制冷回路和旁通支路中的流动路径来调节蒸发器212的工作状态。蒸发器212的工作状态包括供冷状态和化霜状态。
图4是根据本发明一个实施例的用于冷藏冷冻装置10的制冷系统200的示意性结构图。
制冷组件210具有压缩机211。
旁通组件220具有用于流通来自压缩机211的制冷剂以产生热量的旁通加热管225，旁通加热管225与冷藏冷冻装置10的接水盘500热连接。旁通加热管225缠绕于或者至少部分地嵌设于接水盘500，或与接水盘500贴靠设置，以实现热连接。将旁通加热管225缠绕于或者嵌设于接水盘500，可以增大旁通加热管225与接水盘500之间的接触面积，提高热量传递效率，从而有利于积水的快速蒸发。将旁通加热管225贴靠设置于接水盘500上，可以简化热连接的连接过程，降低制造成本。
例如，每一旁通加热管225的入口可以通过连接管路连接至压缩机211 的排气口，或者可以通过连接管路与压缩机211排气口下游的某个区段相连通，只要能够导入流出压缩机211的高压或高温的制冷剂即可。制冷剂在流经旁通加热管225时可以放热冷凝，从而产生热量。
上述连接管路可以与制冷回路内的各个部件之间的连接管路的构造相同，只要能够实现导引制冷剂的功能即可。旁通加热管225可以与冷凝器213的冷凝管的构造大致相同，只要能使流经其的高压或高温的制冷剂能够冷凝放热即可。
由于制冷系统200的旁通组件220具有用于流通来自压缩机211的制冷剂以产生热量的旁通加热管225，且旁通加热管225与接水盘500热连接，来自压缩机211的制冷剂在流经旁通加热管225时能够产生大量的热，能够使接水盘500内的积水吸热而蒸发。因此，本实施例提供了一种新的积水处理方式，使得制冷系统200能够加热冷藏冷冻装置10的接水盘500内的积水，使其吸热蒸发。
制冷组件210还包括蒸发器212，与压缩机211形成制冷回路。
旁通组件220还包括旁通化霜管228，与旁通加热管225串接。即，旁通化霜管228与旁通加热管225通过串接相互连通。且旁通化霜管228与蒸发器212热连接，用于在流经旁通加热管225的制冷剂流入其中时加热蒸发器212。旁通化霜管228缠绕于接水盘500，或与接水盘500贴靠设置，以实现热连接。旁通化霜管228的构造与旁通加热管225的构造可以大致相同。旁通化霜管228与旁通加热管225之间可以通过连接管段进行串接。
本实施例通过改进制冷系统200的结构，提供了一种新的化霜方式。由于旁通组件220还包括与旁通加热管225串接的旁通化霜管228，且旁通化霜管228与蒸发器212热连接，用于在流经旁通加热管225的制冷剂流入其中时加热蒸发器212，制冷剂在流经旁通化霜管228时能够产生大量的热，可使蒸发器212快速化霜。本实施例通过改进蒸发器212的化霜方式，能够实现在蒸发器212化霜的同时，使接水盘500内的积水蒸发，一举两得。
本实施例中，旁通加热管225串接于旁通化霜管228的上游，使得来自压缩机211的制冷剂先流经旁通加热管225再流经旁通化霜管228。由于旁通加热管225串接于旁通化霜管228的上游，来自压缩机211的制冷剂先流经旁通加热管225再流经旁通化霜管228，这使得旁通加热管225能够产生足够的热量加热接水盘500，有利于使接水盘500内的积水充分蒸发。
在一些可选的实施例中，旁通加热管225可以串接于旁通化霜管228的下游。此时，当制冷剂流经旁通化霜管228时能够放出更多热量，这有利于提高蒸发器212的化霜速率。
蒸发器212、旁通化霜管228以及旁通加热管225的数量可以根据实际需要进行设置。在一些实施例中，蒸发器212、旁通化霜管228以及旁通加热管225分别可以为一个。本实施例中，蒸发器212为多个。旁通化霜管228为多个，且与每一蒸发器212一一对应设置。旁通加热管225为多个，且用于与每一蒸发器212对应的接水盘500一一对应设置。旁通化霜管228和旁通加热管225的数量分别与蒸发器212的数量相同。
通过在制冷系统200布置多个蒸发器212，每一蒸发器212对应设置一旁通化霜管228，每一旁通化霜管228连通一旁通加热管225，使得每一蒸发器212均能利用对应的旁通化霜管228产生的热量进行化霜，通过调节旁通化霜管228和旁通加热管225内的制冷剂流通状态，可使多个蒸发器212分别单独化霜。在一蒸发器212化霜时，可以利用不化霜的蒸发器212供冷，这使得本实施例的制冷系统200在提高蒸发器212化霜速率的同时，能够有效防止储物间室110产生明显的温度波动。
例如，蒸发器212可以为两个，且分别为第一蒸发器212a和第二蒸发器212b。
制冷组件210还可以进一步地包括第一制冷节流装置214a和第二制冷节流装置214b，分别设置于制冷回路内。第一制冷节流装置214a串接于第一蒸发器212a的入口，用于对流向第一蒸发器212a的制冷剂节流，被节流的制冷剂流入第一蒸发器212a内可以蒸发吸热从而使得第一蒸发器212a供冷。串接的第一制冷节流装置214a和第一蒸发器212a形成第一制冷支路。第二制冷节流装置214b串接于第二蒸发器212b的入口，用于对流向第二蒸发器212b的制冷剂节流，被节流的制冷剂流入第二蒸发器212b内可以蒸发吸热从而使得第二蒸发器212b供冷。串接的第二制冷节流装置214b和第二蒸发器212b形成第二制冷支路。
串接的第一制冷节流装置214a和第一蒸发器212a，与串接的第二制冷节流装置214b和第二蒸发器212b相互并联设置。即，第一制冷支路与第二制冷支路相互并联设置，这使得制冷系统可以灵活地调节每个蒸发器的工作状态。
旁通化霜管228可以为两个，分别为第一旁通化霜管228a和第二旁通化霜管228b。
旁通组件220还包括旁通供冷管路，其具有第一旁通供冷管路222a和第二旁通供冷管路222b，第一旁通供冷管路222a连接至第一旁通化霜管228a，用于将流经第一旁通化霜管228a的制冷剂导引至第二蒸发器212b，以使第二蒸发器212b产生冷量，第二旁通供冷管路222b连接至第二旁通化霜管228b，用于将流经第二旁通化霜管228b的制冷剂导引至第一蒸发器212a，以使第一蒸发器212a产生冷量。
也就是说，第一旁通供冷管路222a相当于第一旁通化霜管228a与第二蒸发器212b之间的“连接通道”，可以在第一蒸发器212a化霜时将流经第一旁通化霜管228a的制冷剂导引至第二蒸发器212b，使得第二蒸发器212b利用导入的制冷剂供冷。第二旁通供冷管路222ba相当于第二旁通化霜管228b与第一蒸发器212a之间的“连接通道”，可以在第二蒸发器212ba化霜时将流经第二旁通化霜管228b的制冷剂导引至第一蒸发器212ab，使得第一蒸发器212a利用导入的制冷剂供冷。
第一旁通供冷管路222a连接至第二蒸发器212b的入口，且第一旁通供冷管路222a上设置有第一旁通节流装置227a，用于对流向第二蒸发器212b的制冷剂进行节流。第一旁通供冷管路222a用于在第一蒸发器212a利用第一旁通化霜管228a产生的热量进行化霜时，利用第一旁通节流装置227a对流出第一旁通化霜管228a且流向第二蒸发器212b的制冷剂进行节流。也就是说，第一旁通供冷管路222a在导引制冷剂的同时还能利用第一旁通节流装置227a对制冷剂进行节流，使得被节流的制冷剂流经第二蒸发器212b时能够蒸发吸热，从而使得第二蒸发器212b供冷。
第二旁通供冷管路222b连接至第一蒸发器212a的入口，且第二旁通供冷管路222b上设置有第二旁通节流装置227b，用于对流向第一蒸发器212a的制冷剂进行节流。第二旁通供冷管路222ba用于在第二蒸发器212ba利用第二旁通化霜管228b产生的热量进行化霜时，利用第二旁通节流装置227b对流出第二旁通化霜管228b且流向第一蒸发器212a的制冷剂进行节流。也就是说，第二旁通供冷管路222ba在导引制冷剂的同时还能利用第二旁通节流装置227b对制冷剂进行节流，使得被节流的制冷剂流经第一蒸发器212ab时能够蒸发吸热，从而使得第一蒸发器212ab供冷。
利用本实施例的制冷系统200，在一蒸发器212化霜时，由于可以将流经加热该蒸发器212的旁通化霜管228的制冷剂导引并节流后供给另一蒸发器212，以使另一蒸发器212供冷，两个蒸发器212相辅相成，实现了化霜功能和供冷功能的有机结合，这使得本实施例的制冷系统200能够有效地利用压缩机211的机械功，有利于提高制冷系统200及冷藏冷冻装置10的能效。
制冷组件210还可以进一步地包括冷凝器213，设置于制冷回路内，且连接至压缩机211的排气口。例如，冷凝器213可以位于并联设置的两个制冷支路的上游。即，本实施例中的压缩机211、冷凝器213、两个制冷支路依次串接并形成制冷回路。
制冷系统200还可以进一步地包括第一切换阀260，连接至压缩机211的排气口，即，该第一切换阀260的入口连接至压缩机211的排气口。第一切换阀260具有连通冷凝器213的第一阀口、以及连通旁通加热管225的第二阀口。第一阀口为一个，第二阀口可以根据旁通加热管225的数量进行设置，例如可以为一个或多个，且一个第二阀口连通一个旁通加热管225。本实施例中，第二阀口的数量为两个，其中一个第二阀口连通第一旁通加热管225a，另一个第二阀口连通第二旁通加热管225b。
第一切换阀260用于在旁通化霜管228加热蒸发器212时打开连通旁通加热管225的阀口且关闭连通冷凝器213的阀口，以允许流出压缩机211的制冷剂依次流经旁通加热管225和旁通化霜管228，从而加热接水盘500和蒸发器212。在无蒸发器212化霜时，第一切换阀260可以打开连通冷凝器213的阀口且关闭连通旁通加热管225的阀口。第一切换阀260的两个第二阀口不同时地打开，即，两个蒸发器不同时地化霜。
本实施例中，制冷组件210还可以进一步地包括储液包215，设置于制冷回路内，例如，可以设置于两个制冷支路的下游，且位于压缩机211的吸气口的上游，用于调节制冷组件210的各个部件所需的制冷剂的量。
制冷组件210还可以进一步地包括制冷回气管，设置于制冷回路内，例如，可以设置于储液包215与压缩机211的吸气口之间，用于降低回流至压缩机211吸气口的制冷剂的过热度。
当蒸发器212、旁通化霜管228、以及旁通加热管225分别为一个时，旁通化霜管228的出口可以连接至制冷回气管，使得流经旁通化霜管228的 制冷剂可以经由制冷回气管回流至压缩机211的吸气口，这可以减少或避免因蒸发器212化霜而导致压缩机211的吸气温度过高。
在一些可选的实施例中，制冷组件210还可以进一步地包括第二切换阀，连接至冷凝器213的出口(即，第二切换阀的入口连接至冷凝器213的出口)，且其具有连通第一制冷节流装置214a的阀口以及连通第二制冷节流装置214b的阀口。第二切换阀根据第一蒸发器212a和第二蒸发器212b的工作状态调节流经其的制冷剂的流动路径。例如，在第一蒸发器212a和第二蒸发器212b供冷时，第二切换阀可以打开两个阀口，在任一蒸发器212化霜时，第二切换阀可以关闭两个阀口。通过增设第二切换阀，可以提高制冷系统200运行的可靠性。
制冷组件210还可以进一步地包括防露管219、过滤器216、散热风机217。防露管219和过滤器216可以依次串接于冷凝器213的下游，并位于第一制冷节流装置214a和第二制冷节流装置214b的上游。例如防露管219可以用于设置于冷藏冷冻装置10的门体四周的边缘部位，防止门体边缘凝露。过滤器216起到过滤制冷剂中的杂质、防止产生冰堵的作用。散热风机217可以靠近设置于冷凝器213设置，用于加快冷凝器213向周围散热。
在一些可选的实施例中，箱体100的内部还形成有用于安装蒸发器212的安装空间120。该安装空间120可以位于储物间室110的一侧，例如下侧或者后侧。冷藏冷冻装置10还可以进一步地包括保温隔板130，设置于安装空间120内，并将安装空间120分隔出两个子空间。子空间可以按照一左一右或者一上一下的方式布置，使得蒸发器212可以并列布置或者上下叠置，这可以节约蒸发器212的安装空间120，提高空间利用率，且提高美观度。
每个子空间分别用于安装一个蒸发器212，以减少蒸发器212之间的热交换，这可以避免化霜的蒸发器212所产生的热量影响另一蒸发器212的供冷效果。
箱体100内形成有两个送风风道，与蒸发器212一一对应，每一送风风道用于将对应蒸发器212所提供的冷量输送至储物间室110。每个送风风道相互独立设置，这可以避免气流乱流，保证冷量输送效率，提高储物间室110的保鲜效果。每个送风风道通过风门700与对应蒸发器212所在空间连通。
相应地，冷藏冷冻装置10还可以进一步地包括两个送风风机600，与蒸发器212一一对应设置，用于在对应蒸发器212提供冷量时促使形成流经对 应送风风道以及储物间室110的换热气流。送风风机600可以仅在对应蒸发器212供冷时开启。且送风风机600可以采用送风风机600遮蔽手段防止蒸发器212化霜时产生的热量进入储物间室110。在一些可选的实施例中，送风风机600的数量也可以变换为一个，设置于两个送风风道与储物间室110之间的公共流路上，使得该送风风机600可以同时作为两个送风风道的气流促动装置，这有利于进一步简化冷藏冷冻装置10的结构。
本发明的用于冷藏冷冻装置10的制冷系统200以及冷藏冷冻装置10，由于制冷系统200的旁通组件220具有用于流通来自压缩机211的制冷剂以产生热量的旁通加热管225，且旁通加热管225用于与冷藏冷冻装置10的接水盘500热连接，来自压缩机211的制冷剂在流经旁通加热管225时能够产生大量的热，能够使接水盘500内的积水吸热而蒸发。因此，本发明提供了一种新的积水处理方式，使得制冷系统200能够加热冷藏冷冻装置10的接水盘500内的积水，使其吸热蒸发。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
