本发明涉及一种均匀变温室以及具有该均匀变温室的冰箱。
背景技术
为了方便用户储藏物品，现有冰箱一般都设置有抽屉组件，包括抽屉间室以及收容于所述抽屉间室内的抽屉。所述抽屉间室的后壁上侧设置有向所述抽屉内送风的送风口，下侧设置有回风口，从而使得冷气流在抽屉间室内循环。然而，此种送风、回风方式不能够使冷气流在抽屉内循环充分，容易存在冷气流的流动死角或者出现短路回流现象，不利于抽屉间室的充分、快速降温。当抽屉内放置有物品时，物品易于将冷气流挡住，不利于冷气流的充分移动。
鉴于上述问题，有必要提供一种均匀变温室以及具有该均匀变温室的冰箱，以解决上述问题。
发明内容
针对现有技术的不足，本发明解决的技术问题是提供一种均匀变温室以及具有该均匀变温室的冰箱，该均匀变温室能够使得冷气充分循环实现快速、充分、均匀降温的目的，进而提高物品保存效果。
为解决上述技术问题，本发明的技术方案是这样实现的：
一种均匀变温室，用于冰箱，包括间室以及收容于所述间室内的抽屉，所述间室包括供抽屉进出的开口、与所述开口相对设置的后侧壁、位于所述后侧壁两侧的左侧壁和右侧壁、顶侧壁以及底侧壁，所述顶侧壁上设置有向所述抽屉内送风的送风口，所述左侧壁、右侧壁以及后侧壁中至少一个设置有回风口，从而在所述抽屉内部形成冷气循环，同时在所述抽屉与所述间室各侧壁之间也形成冷气循环。
进一步地，所述回风口与所述底侧壁的距离可小于其与所述顶侧壁的距离。
进一步地，所述送风口的数量可为正奇数个，一个位于所述顶侧壁的轴线上，其余的在所述顶侧壁的轴线两侧对称分布。
进一步地，所述送风口的数量可为三个，一个位于所述顶侧壁的轴线上，另外两个在所述顶侧壁的轴线两侧对称分布。
进一步地，所述送风口的数量可为正偶数个，且在所述顶侧壁的轴线两侧对称分布。
进一步地，所述后侧壁、左侧壁以及右侧壁都可具有所述回风口。
进一步地，所述抽屉包括底壁以及多个侧壁，每个所述侧壁顶端与所述间室的顶侧壁之间形成有第一间隙以便冷气经所述第一间隙流出所述回风口。
进一步地，所述抽屉的侧壁与所述间室的左侧壁、右侧壁、后侧壁之间形成有所述第二间隙以便冷气经第二间隙流出所述回风口，所述第二间隙的大小沿着抽屉高度方向自上而下逐渐变大。
进一步地，所述回风口位于所述间室的左侧壁和右侧壁上。
本发明还提供了一种冰箱，包括送风系统以及回风系统，所述冰箱还设置有上述任一均匀变温室，其中所述均匀变温室的送风口、回风口分别与所述送风系统、回风系统相连通。
本发明的有益效果是：相较于现有技术，本发明的均匀变温室能够使得冷气充分循环，从而实现快速、充分、均匀降温的目的，提高物品保存效果。

具体实施方式
为了使本发明的目的、技术方案和优点更加清楚，下面结合附图和具体实施例对本发明进行详细描述。
参见图1和图2，本发明的均匀变温室100用于冰箱，均匀变温室100包括间室10以及收容于间室10内的抽屉20。
参见图1、图2、图3以及图4，间室10包括供抽屉20进出的开口11、 与开口11相对设置的后侧壁12、位于后侧壁12两侧的左侧壁13和右侧壁14以及垂直于左侧壁13设置的顶侧壁15、底侧壁16，后侧壁12、左侧壁13、右侧壁14、顶侧壁15以及底侧壁16共同围设成一收容空间17以收容抽屉20。
顶侧壁15上设置有若干向抽屉20内输送冷风的送风口151。送风口151的数量为正奇数个，一个位于顶侧壁15在抽屉20进出方向的轴线上，其余的在轴线两侧对称分布。当然，送风口151的数量也可为正偶数个，且在轴线两侧对称分布。本实施方式中，送风口151具体为三个，一个位于顶侧壁15在抽屉20进出方向的轴线上，另外两个在轴线两侧对称分布，从而该三个送风口151能够将冷风吹入抽屉20底部，接着冷风再沿着抽屉20侧壁向上流出以形成冷气涡流。
左侧壁13、右侧壁14以及后侧壁12上分别设置有回风口18，回风口18与送风口151共同作用以使得抽屉20内部形成冷气循环。回风口18与底侧壁16的距离小于其与顶侧壁15的距离，且较佳地，回风口18尽量靠近底侧壁16设置。
参见图2和图3，抽屉20包括底壁21以及若干侧壁22，底壁21、侧壁22共同围设成一储藏空间23以便储藏物品。抽屉20侧壁22的顶端与间室10的顶侧壁15之间形成第一间隙221，与间室10的后侧壁12、左侧壁13以及右侧壁14之间形成第二间隙222，冷气经第一间隙221、第二间隙222汇流至回风口18，从而使得抽屉20与间室10的后侧壁12、左侧壁13以及右侧壁14之间形成冷气循环。抽屉20还包括手柄24以便将抽屉20抽拉出间室10的收容空间17。
当使用本发明的均匀变温室100时，冷风自送风口151进入到抽屉20内，并沿着抽屉20的底壁21向抽屉20的侧壁22流动，然后再沿着抽屉20的侧壁22向间室10的顶侧壁15流动，并经第一间隙221、第二间隙222汇流至回风口18，从而使得冷风在抽屉20内循环时可以到达抽屉20内的各个区域，同时抽屉20与间室10的后侧壁12、左侧壁13以及右侧壁14之间亦形成冷气循环，进而实现快速、充分、均匀降温的目的。图2、图3中箭头所示为冷风在均匀变温室100内的流动示意图。
本发明的均匀变温室100通过在顶侧壁15上设置若干向抽屉20内输送冷风的送风口151，从而大量的冷风会从送风口151吹入并在抽屉20内形 成冷气循环，进而均匀变温室100能够快速冰镇冷却饮料、啤酒等饮品，实现快速冰镇的功能。
图5示出了本发明均匀变温室200的第二实施例，根据该实施例的均匀变温室200的结构与均匀变温室100的结构基本相同，不同之处在于均匀变温室200的回风口218只设置在左侧壁213上，送风口251设置在顶侧壁215远离回风口218的一侧。在其它实施例中，回风口218亦可以只设置在右侧壁214或者底侧壁上。本领域技术人员可以理解，在其他实施例中，回风口218也可设置在间室的左侧壁和右侧壁上。
图6示出了本发明均匀变温室300的第三实施例，根据该实施例的均匀变温室300的结构与均匀变温室100的结构基本相同，不同之处在于均匀变温室300的回风口318只设置在后侧壁312上，送风口351设置在顶侧壁315远离回风口318的一侧。
本发明还提供了一种冰箱，该冰箱具有送风系统、回风系统以及均匀变温室100或者均匀变温室200或者均匀变温室300，其中均匀变温室100或者均匀变温室200或者均匀变温室300的送风口与送风系统相连通，回风口与回风系统相连通。
相较于现有技术，本发明实施例的均匀变温室100、均匀变温室200、均匀变温室300能够使得冷气充分循环，从而实现快速、充分、均匀降温的目的，提高物品保存效果。
特别需要指出，对于本领域的普通技术人员来说，在本发明的教导下所作的针对本发明的等效变化，仍应包含在本发明申请专利范围所主张的范围中。
