【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做出创造性劳动前提下所获得的所有其他实施例，均属于本申请保护的范围。
请参阅图1所示，冰箱100包括第一保鲜室110、吸附塔120、阀门130和气泵140。气泵140的进气口连通于第一保鲜室110。气泵140的出气口通过阀门130的进气通道连通于吸附塔120的进气口。吸附塔120的进气口通过阀门130的出气通道连通于第一保鲜室110。阀门130进气通道开启，使气泵140将第一保鲜室110的空气加压传输至吸附塔120，吸附塔120过滤出空气中的氧气，由吸附塔120的出气口排出，并吸附余气；阀门130的进气通道关闭，使气泵140停止向吸附塔120加压传输空气，吸附塔120释放余气，经由吸附塔120的进气口及阀门130的出气通道排至第一保鲜室110。
在本实施例冰箱实现保鲜的过程中，将第一保鲜室110中的空气抽出进行去氧过滤，然后将排除氧气的剩余气体返还至第一保鲜室110，通过该过程使得第一保鲜室110内的氧气含量减小，可以实现控氧保鲜；并可使第一保鲜室110内空气总含量降低，使第一保鲜室110内空气处于负压状态，实现负压保鲜，即可以实现控氧保鲜和负压保鲜的双重保鲜效果。
在本实施例中，阀门130中包括独立的进气通道和出气通道，因此阀门130中至少包括3个端口。如图1所示，3个端口至少分为第一端口131、第二端口132和第三端口133。阀门130的第一端口131与吸附塔120的进气口相连通。阀门130的第二端口132与气泵140的出气口相连通。阀门130的第一端口131和第二端口132之间为进气通道，从而气泵140的出气口可通过阀门130的进气通道连通于吸附塔120的进气口。另外，阀门130的第三端口133与第一保鲜室110相连通，阀门130的第三端口133和阀门130的第一端口131之间为出气通道，从而吸附塔120的进气口可通过阀门130的出气通道连通于第一保鲜室110。通过阀门130可以实现气体流动方向的切换。
在另一实施例中，如图2所示，阀门130也可以包括4个端口。4个端口可 以分为第一端口131、第二端口132、第三端口133和第四端口134。吸附塔120的进气口与第一端口131和第四端口134相连通。阀门130的第二端口132与气泵140的出气口相连通，阀门130的第一端口131与阀门130的第二端口132之间构成进气通道。阀门130的第三端口133与第一保鲜室110相连通，阀门130的第四端口134与阀门130的第三端口133之间构成出气通道。从而阀门130只需要切换进气通道和出气通道的启闭，就可以切换气体流动方向，从而控制第一保鲜室110气体的流进流出。
吸附塔120可以至少设置有两个，通过至少两个吸附塔120可以持续地对第一保鲜室110内的空气进行氧气排出，并可以持续地将吸附塔120吸附的余气脱附到第一保鲜室110内，高效低耗时地控制第一保鲜室110内的氧含量。具体地，至少两个吸附塔120可分为第一吸附塔121和第二吸附塔122。
相应地，阀门130对应每一第一吸附塔121具有一第一进气通道和一第一出气通道。对应每一第二吸附塔122具有一第二进气通道和一第二出气通道。交替控制阀门130中第一进气通道开启和第二进气通道关闭，或者第一出气通道关闭和第二进气通道开启，从而可以做到在第一吸附塔121和第二吸附塔122中的一个吸附时，将从第一吸附塔121和第二吸附塔122中的另一个脱附出的余气通过出气通道流入到第一保鲜室110内，高效低耗时地控制第一保鲜室110内的氧含量。
阀门130的第一端口131和阀门130的第三端口133也可至少设置多个。阀门130的第一端口131的数目和第三端口133的数目可与吸附塔120的数目相同。每一吸附塔120的进气口可与一第一端口131相连。每一第一端口131与其对应的第三端口133之间可构成出气通道。所有第三端口133均连通于第一保鲜室110。另外，阀门130的第二端口132可设置一个，每一第一端口131和第二端口132之间可构成一进气通道。
在又一个实施例中，如图3和图4所示，吸附塔120的数目为两个。阀门130为两位五通电磁阀，通过两位五通电磁阀可以自如地切换阀门130内部的第一出气通道、第二出气通道、第一进气通道和第二进气通道的启闭，从而实现切换两个吸附塔120的工作状态，从而可以做到在第一吸附塔121和第二吸附塔122中的一个吸附时，将从第一吸附塔121和第二吸附塔122中的另一个脱附出的余气通过出气通道流入到第一保鲜室110内，从而可以控制阀门130和 气泵140的运行可以实现持续地对第一保鲜室110内的空气进行氧气排出，并可以持续地将吸附塔120吸附的余气脱附并传输到第一保鲜室110内，高效低耗时地控制第一保鲜室110内的氧含量。
如图5所示，两位五通电磁阀可包括两个第一端口131，一个第二端口132和两个第三端口133。其中一个第一端口131与第一吸附塔121的进气口相连通，另一个第一端口131与第二吸附塔122的进气口相连通。与第一吸附塔121的进气口连接的第一端口131与其对应的第三端口133之间构成第一出气通道。与第二吸附塔122的进气口连接的第一端口131与其对应的第三端口133之间构成第二出气通道。所有第三端口133均连通于第一保鲜室110。与第一吸附塔121的进气口连接的第一端口131与第二端口132之间构成第一进气通道。与第二吸附塔122的进气口连接的第一端口131与第二端口132之间构成第二进气通道。
在本实施例中，吸附塔120中可设置有吸附物质。吸附塔120内设置的吸附物质处于吸附状态时，吸附物质对氮的吸附能力大于对氧的吸附能力。吸附塔120内设置的吸附物质可以是沸石分子筛颗粒。空气中的氮气的极性较氧气的大，沸石分子筛具有对空气中的氧氮各组成具有不同的吸附能力，可以通过沸石分子筛从空气中优先吸附氮气，可以将空气中的氧气过滤出去，从而空气从吸附塔120的进气口进入，经过沸石分子筛的吸附，从吸附塔120流出的空气中的氧气含量超过空气内的氧气含量。进而从沸石分子筛脱附出的气体中的氧气含量明显低于空气内的氧气含量，即沸石分子筛脱附出的气体为低氧含量气体，通过将沸石分子筛脱附出的气体传输到第一保鲜室110内，可以降低第一保鲜室110内氧气的含量，提高保鲜效果。沸石分子筛颗粒的尺寸可为0.4mm～0.8mm，具体可为0.5mm、0.6mm、0.7mm。当然，在其他实施例中，吸附塔120内设置的吸附物质还可以是磷酸硅铝分子筛。
即本申请是通过吸附塔120的吸附和脱附控制第一保鲜室110氧含量的，由于吸附物质具有吸附量随被吸附组分分压的增加而增加的特性，本实施例通过压力变化完成吸附和解附而实现空气分离，即通过压力变化使吸附塔120处于吸附或脱附状态。具体地，本实施例通过气泵140增加空气的压力，使空气变为压缩空气，进而将压缩空气传入到吸附塔120中，变相地增加吸附塔120内的压力，从而使吸附塔120处于吸附阶段，即使吸附塔120将压缩空气中的 至少部分氧气过滤出去，在气泵140不再将压缩空气传输到吸附塔120内时，吸附塔120压力降低，吸附塔120对其吸附的氮气等物质的吸附能力降低，吸附塔120会将其内吸附的物质解附出来，并通过吸附塔120的进气口、阀门130的出气通道流入到第一保鲜室110内，即将吸附塔120脱附出来的余气流入到第一保鲜室110内，使第一保鲜室110内氧气含量降低，可以实现控氧保鲜；并可使第一保鲜室110内空气总含量降低，使第一保鲜室110内空气处于负压状态，实现负压保鲜，即可以实现控氧保鲜和负压保鲜的双重保鲜效果。对应于沸石分子的颗粒大小，在本实施例中，气泵140将空气加压至0.12MPa～0.2MPa。
沸石分子筛的颗粒大小和气泵140对空气的加压对应关系，可实现气泵140的小型化，减小冰箱100的功率消耗，减小噪声。沸石分子筛的粒径若过小，则气流传输阻力过大，就需要适当增加压力。从而吸附塔120内填充的沸石分子的粒径应当较均匀且较适中，例如将沸石分子筛颗粒的尺寸设置为0.4mm～0.8mm，就可以不需要气泵140对空气增加过多压力，可以实现气泵140的小型化，减小冰箱100的功率消耗，减小噪声。
在本实施例中，吸附塔120可为圆柱形。当然吸附塔120也可呈正方体、长方体等其他规则或不规则形状。
可以通过控制吸附塔120的尺寸控制吸附塔120的吸附容量，将吸附塔120的尺寸控制在一个恰当的范围内时既可以保证吸附塔120的吸附容量又可以保持较小体积。具体地，吸附塔120的直径范围可为20mm-30mm。吸附塔120的高度范围可为150mm-300mm。可选地，吸附塔120的直径可为20mm、22mm、24mm、25mm或27mm。吸附塔120的高度可为160mm、186mm、200mm、230mm或250mm。
对应于吸附塔120的小尺寸设计，气泵140的传输流量也做对应的设计。可以通过改变气泵140的传输流量改变压缩空气中的分子与吸附塔120内的吸附物质的接触时间，从而改变吸附塔120对压缩空气的吸附效率。传输速度过快，会使压缩空气中的分子与吸附物质接触时间过短，不利于气体的吸附，降低吸附速率；传输速度过低，又会使吸附塔120容积增大。因此，传输流量要控制在一定的范围之内，在本实施例中，气泵140的传输流量为5L/min～15L/min，具体可为7L/min、9L/min或11L/min。当然，为保持吸附塔120的吸附效率， 气泵140每秒的传输流量与吸附塔120的容积的比值可为1.2～2.2。
第一保鲜室110可以是密闭空间，从而第一保鲜室110内空气不与大气相连通，进而可以通过去除第一保鲜室110内部的空气中的至少部分氧气且重新将去除氧气后的空气返还到第一保鲜室110内，可以使第一保鲜室110的含氧量降低，可以实现控氧保鲜；并可使第一保鲜室110内空气总含量降低，使第一保鲜室110内空气处于负压状态，实现负压保鲜，即可以实现控氧保鲜和负压保鲜的双重保鲜效果，从而实现更好的保鲜效果。
第一保鲜室110可以设置一个或多个。第一保鲜室110可以是存储蔬菜、水果类等食材的保鲜室。通过将第一保鲜室110的含氧量控制在较低水平，可以降低其内储存的食材的呼吸速率，抑制食材的新陈代谢，达到保鲜作用，并可以抑制变质、细菌的繁殖。
第一保鲜室110可设置有第一传感器。第一传感器可以用于检测第一保鲜室110的含氧量，在第一传感器检测到的第一保鲜室110的含氧量高于第一阈值时，可以控制气泵140和阀门130，通过气泵140、阀门130和吸附塔120共同控制第一保鲜室110内含氧量，使第一保鲜室110含氧量降低。在第二传感器检测到的含氧量低于第二阈值时，可以控制气泵140停止运行，即不再通过气泵140、阀门130和吸附塔120共同控制第一保鲜室110的含氧量。第一传感器连接气泵140。第一传感器还可以连接阀门130。
第一保鲜室110可设置有第二传感器。第二传感器用于检测第一保鲜室110是否打开。可以在第二传感器检测到第一保鲜室110打开时，可以控制气泵140和阀门130，通过气泵140、阀门130和吸附塔120共同作用控制第一保鲜室110内的含氧量，第一保鲜室100含氧量降低。第二传感器连接气泵140。第一传感器还可以连接阀门130。
在本实施例中，冰箱100还可进一步包括控制器。控制器可与气泵140和阀门130连接，可以控制气泵140的运行，还可以控制阀门130内进气通道和出气通道的启闭。
进一步地，控制器还可与第一传感器连接，用于接收第一传感器检测到的数据。当然，控制器还可以根据检测到的数据分析是否需要通过气泵140、阀门130和吸附塔120控制第一保鲜室110的含氧量，并根据分析的结果控制气泵140和阀门130的运转。
进一步地，控制器还可与第二传感器连接，用于接收第二传感器检测到的数据。当然，控制器还可以根据第二传感器检测到的数据分析是否需要通过气泵140、阀门130和吸附塔120控制第一保鲜室110的含氧量，并根据分析的结果控制气泵140和阀门130的运转。
在本实施例中，吸附塔120的出气口还设有出气开关。吸附塔120处于吸附状态时，出气开关开启，从而未被吸附塔120内吸附物质吸附的气体可以通过吸附塔120的出气口排出。吸附塔120处于解附状态时，出气开关关闭，从而吸附塔120脱附出来的气体只能通过吸附塔120的进气口和阀门130的进气通道流入到第一保鲜室110内，并且可以避免外界的空气通过吸附塔120的出气口进入到吸附塔120内，进而以防外界的空气与吸附塔120脱附出来的气体一同流入到第一保鲜室110内，保证第一保鲜室110含氧量的降低效率。
在本实施例中，冰箱100还进一步包括第二保鲜室150。吸附塔120的出气口连通至第二保鲜室150。即第二保鲜室150可以接收吸附塔120排出的富氧气体，从而第二保鲜室150的氧含量增加。第二保鲜室150可以存储有肉类食材，通过增加第二保鲜室150内的氧含量可以保证实现其内存储的肉类保鲜颜色更鲜艳。
如图6和图7所示，具体来说，第一保鲜室110以抽屉的方式设置在冰箱100中，吸附塔120和阀门130设置在第一保鲜室110后面，即吸附塔120和阀门130设置在第一保鲜室110远离冰箱100门的一侧，使得在拉开第一保鲜室110时，不会影响阀门130和吸附塔120的位置，避免影响阀门130、吸附塔120和气泵140之间的连接关系。气泵140设置在冰箱100底部。第一保鲜室110与气泵140的进气口之间、气泵140的出气口与阀门130之间、吸附塔120与阀门130之间均可通过气管连接，从而在拉开第一保鲜室110时，不干扰气口之间的连接。气管可为软胶气管或硬质气管。
进一步地，在吸附塔120的数目为两个时，为了使整个冰箱100的结构布局更为紧凑，吸附塔120可以并排设置，且所有吸附塔120的进气口均朝向同一方向设置。
总而言之，在冰箱100实现保鲜的过程中，将第一保鲜室110中的空气抽出进行去氧过滤，然后将排除氧气的剩余气体返还至第一保鲜室110，通过该过程使得第一保鲜室110内的氧气减小，可以实现控氧保鲜；并可使第一保鲜室 110内空气总含量降低，使第一保鲜室110内空气处于负压状态，实现负压保鲜，即可以实现控氧保鲜和负压保鲜的双重保鲜效果。
以上仅为本申请的实施方式，并非因此限制本申请的专利范围，凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本申请的专利保护范围内。
