Description

用于冷藏冷冻装置的门体及冷藏冷冻装置 技术领域
本发明涉及冷藏冷冻技术，特别是涉及一种用于冷藏冷冻装置的门体及冷藏冷冻装置。
背景技术
为了满足人们的需求，现有的一些冰箱上设置有具备触摸显示功能的显示控制组件。为了便于用户操作，显示控制组件一般都设置在冰箱的门体上。冰箱的门体一般都为薄板状构件，其内必须留有用于安装显示控制组件的容纳腔，因此与容纳腔相对的门体发泡层的厚度相对较薄，冰箱储物空间内的部分冷量易通过该厚度较薄的发泡层泄漏至容纳腔。同时，容纳腔是一个相对比较封闭的空间，显示控制组件在运行过程中产生的大量热量无法有效散出，由此，在容纳腔中会出现冷热交界现象，导致显示控制组件产生凝露，进而使得显示控制组件极易损坏，严重降低了整个门体的质量。
为了解决凝露问题，现有技术中通常采用加大发泡层厚度或加大显示控制组件和门体的装配间隙这两种方式，然而这非但不能较好地散发显示控制组件产生的热量，还会使得整个门体的厚度增加。
发明内容
本发明第一方面的一个目的旨在克服现有技术中的至少一个缺陷，提供一种用于冷藏冷冻装置的能够有效避免显示控制组件产生凝露的门体。
本发明第一方面的另一个目的是加速显示控制组件所在空间与环境空间之间的空气流通，从而进一步避免显示控制组件产生凝露。
本发明第二方面的目的是提供一种冷藏冷冻装置。
根据本发明的第一方面，本发明提供一种用于冷藏冷冻装置的门体，包括：用于形成门体前部的面板；用于提供显示触控功能的显示控制组件；以及用于形成门体后部的门体发泡组件；其中门体发泡组件和面板之间限定有用于容纳显示控制组件的容纳腔、以及连通容纳腔和环境空间的进风风道和出风风道，显示控制组件容纳在容纳腔中，出风风道包括多个间隔开的子风道，每个子风道在其出风方向上均与显示控制组件的发热集中部件相对。
可选地，显示控制组件包括前后依次排列的前门衬和后门衬、分别用于形成显示控制组件上端和下端的上饰条和下饰条以及分别用于形成显示控制组件的横向两侧的两个侧边框，前门衬、后门衬、上饰条、下饰条以及两个侧边框之间形成有发泡保温层；且前门衬的前向表面设有向后凹进以用于形成容纳腔、进风风道和出风风道的凹陷。
可选地，每个子风道的后壁距前门衬前向表面的距离均小于容纳腔的后壁距前门衬前向表面的距离；且每个子风道均通过一滑坡与容纳腔相连，滑坡与子风道的后壁和容纳腔的后壁均光滑连接。
可选地，显示控制组件包括用于显示信息及接收触摸操作的触摸显示屏、用于为触摸显示屏的背光元件提供电源的背光板以及用于支撑触摸显示屏和背光板的安装板架；且子风道的数量为两个，两个子风道在竖直方向上分别与背光元件和背光板相对。
可选地，显示控制组件的前侧贴附于面板的后向表面，显示控制组件的后侧与容纳腔的后壁之间留有间隙，以形成供空气流通的中间风道；且进风风道与容纳腔的下部连通，出风风道与容纳腔的上部连通，以使得进风风道、中间风道和出风风道共同形成上下贯穿的散热风道。
可选地，进风风道内设有进风风机，进风风机配置成在显示控制组件所处空间内的湿度达到预设的第二湿度阈值时受控地启动，以促使环境空气经进风风道流向容纳腔。
可选地，进风风机为前侧与面板之间留有间隙的离心风机，离心风机具有朝向前侧的进风口和朝向容纳腔的出风口。
可选地，门体发泡组件内埋置有加热装置，加热装置配置成在显示控制组件所处空间内的湿度达到预设的第一湿度阈值时受控地启动，并向门体发泡组件的前部提供热量。
可选地，加热装置的发热区段均匀地分布在前门衬后向表面的位于显示控制组件正后方的区域内。
根据本发明的第二方面，本发明提供一种冷藏冷冻装置，包括：箱体，其内限定有用于存放物品的储物空间；以及上述任一的门体，门体直接或间接地连接于箱体，以打开和/或关闭至少部分储物空间。
本发明的用于冷藏冷冻装置的门体包括面板、门体发泡组件以及设置于面板和门体发泡组件之间的显示控制组件，门体发泡组件和面板之间限定有 容纳腔、进风风道和出风风道，且出风风道包括多个间隔开的子风道，每个子风道在出风风道的出风方向上均与显示控制组件的发热集中部分相对。由此，可使得空气流以较高的流速相对较多地流经显示控制组件的发热集中部分，从而更加有效地带走显示控制组件的发热集中部分所产生的热量。
进一步地，由于门体内的进风风道、中间风道和出风风道共同形成上下贯穿的散热风道，由此，散热风道可与环境空间之间形成空气流循环，显示控制组件产生的热量可通过该散热风道散发出去，从而降低了显示控制组件周围的温度，减小了显示控制组件所处空间的发泡侧与显示控制组件侧之间的温差，减少甚至避免该空间内出现冷热交界现象，进而进一步避免显示控制组件(尤其是显示控制组件的背部及其触摸显示屏)上产生凝露，提高了显示控制组件的质量，延长了其使用寿命。
进一步地，由于进风风道内设有受控地启动的进风风机，其能够促使环境空气经进风风道流向显示控制组件所在的容纳腔，也就是说，进风风机能够加速显示控制组件所处空间与环境空间之间的空气流动，不但能够更加有效地带走显示控制组件所产生的热量，而且还能够通过空气的加速流通产生明显的防凝露效果。
进一步地，由于门体发泡组件内埋置有受控地向其前部提供热量的加热装置。由此，可在显示控制组件所处空间内的湿度达到预设的第一湿度阈值时通过加热装置适当地提高门体发泡组件前部的温度，同样能够减小显示控制组件所处空间的发泡侧与显示控制组件侧之间的温差，从而减少甚至避免该空间内出现冷热交界现象，进而避免显示控制组件(尤其是显示控制组件的背部及其触摸显示屏)上产生凝露。
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

具体实施方式
本发明实施例首先提供一种用于冷藏冷冻装置的门体，图1是根据本发明一个实施例的用于冷藏冷冻装置的门体的示意性结构图，图2是根据本发明一个实施例的用于冷藏冷冻装置的门体的示意性部分结构分解图。参见图1至图2，本发明实施例的用于冷藏冷冻装置的门体1包括用于形成门体1前部的面板10、用于提供显示触控功能的显示控制组件30以及用于形成门体1后部的门体发泡组件20。显示控制组件30设置于门体发泡组件20和面板10之间，也就是说，显示控制组件30设置于门体发泡组件20的前侧、且位于面板10的后侧。
图3是根据本发明一个实施例的用于冷藏冷冻装置的门体的示意性结构分解图。参见图2和图3，在本发明的一些实施例中，门体发泡组件20和面板10之间限定有用于容纳显示控制组件30的容纳腔261、以及连通容纳腔261和环境空间的进风风道262和出风风道263，显示控制组件30容纳在容纳腔261中，出风风道263包括多个间隔开的子风道2631，每个子风道2631在出风风道263的出风方向上均与显示控制组件30的发热集中部分相对。具体地，出风风道263的出风方向为从下往上的竖直方向，即每个子风道2631在竖直方向上均与显示控制组件30的发热集中部分相对。由此，可使得空气流以较高的流速相对较多地流经显示控制组件30的发热集中部分，从而更加有效地带走显示控制组件30的发热集中部分所产生的热量。需要 注意的是，本发明实施例中所说的“多个”意指两个、三个或多于三个的更多个。显示控制组件30的发热集中部分意指显示控制组件30的产生热量较多的部分，例如下文将描述到的背光元件、背光板、电路板等。
在本发明的一些实施例中，参见图3，显示控制组件30可包括前后依次排列的前门衬21和后门衬22、分别用于形成显示控制组件30上端和下端的上饰条23和下饰条24以及分别用于形成显示控制组件30的横向两侧的两个侧边框25，前门衬21、后门衬22、上饰条23、下饰条24以及两个侧边框25之间形成有发泡保温层(图中未示出)。也就是说，前门衬21、后门衬22、上饰条23、下饰条24以及两个侧边框25之间可通过卡接或螺钉连接的方式固定在一起，并且在其间限定有发泡空间，该发泡空间内发泡形成有用于保温隔热的发泡保温层。进一步地，前门衬21的前向表面设有向后凹进以用于形成容纳腔261、进风风道262和出风风道263的凹陷。
进一步地，每个子风道2631的后壁距前门衬21前向表面的距离均小于容纳腔261的后壁距前门衬21前向表面的距离。也就是说，每个子风道2631向后凹进的程度均小于容纳腔261向后凹进的程度。由此，可尽可能地保证出风风道263与容纳腔后部形成的中间风道在前后方向上的厚度大致相等，从而保证气流流速的稳定性。进一步地，进风风道262的后壁距前门衬21前向表面的距离也小于容纳腔261的后壁距前门衬21前向表面的距离，即进风风道262向后凹进的程度也小于容纳腔261向后凹进的程度。进风风道262的后壁距前门衬21前向表面的距离可等于每个子风道2631的后壁距前门衬21前向表面的距离，进风风道262向后凹进的程度与每个子风道2631向后凹进的程度相同。
每个子风道2631均通过一滑坡264与容纳腔261相连，该滑坡264与子风道2631的后壁和容纳腔261的后壁均光滑连接，以更好地引导空气流从容纳腔261流向子风道2631，减小空气流动阻力，进一步避免产生凝露。进一步地，进风风道262通过另一滑坡265与容纳腔261相连，该另一滑坡265与进风风道262的后壁以及容纳腔261的后壁均光滑连接。
在本发明的一些实施例中，参见图3，显示控制组件30包括用于显示信息及接收触摸操作的触摸显示屏31、用于为触摸显示屏31的背光元件(图中未示出)提供电源的背光板32以及用于支撑触摸显示屏31和背光板32的安装板架33。在显示控制组件30的运行过程中，背光元件和背光板32 均会产生大量的热量。因此，在本发明的一些实施例中，子风道2631的数量可设置为两个，两个子风道2631在竖直方向上分别与背光元件和背光板32相对，以分别用于散发背光元件和背光板32产生的热量。
具体地，触摸显示屏31后侧的背光元件可布置在与背光板32所在一侧横向相对的另一侧，并大致分布在沿竖直方向延伸的一长条形区域内。在竖直方向上与背光元件相对的子风道2631的宽度大致与该长条形区域的宽度相当，以尽可能将背光元件散发的热量全部有效地散发掉。进一步地，安装板架33上可开设有与背光元件一一对应的通风孔331，以使每个背光元件散发的热量均经相应的通风孔散发至散热通道，然后再经子风道2631送出。
在本发明的一些替代性实施例中，子风道2631的数量还可以为多于两个的更多个，每个子风道2631在竖直方向上均与显示控制组件30的某一或某些发热集中部分相对。例如，子风道2631的数量还可以为三个，三个子风道2631在竖直方向上分别与背光元件、背光板32以及电路板34(将在下面详述)相对。
进一步地，显示控制组件30还包括用于对触摸显示屏31的显示和触摸信息进行处理的电路板34。电路板34安装在安装板架33上，并位于触摸显示屏31的上侧、下侧或任一横向侧。也就是说，触摸显示屏31与电路板34大致平行设置，因此，增加了触摸显示屏31和电路板34的散热面积，以便更加均匀地散热，避免了因触摸显示屏31和电路板34前后叠加设置带来的无法散热或散热不均的问题。
在本发明的一些实施例中，显示控制组件30的前侧贴附于面板10的后向表面，显示控制组件30的后侧与容纳腔261的后壁之间留有间隙，以形成供空气流通的中间风道。进风风道262与容纳腔261的下部连通，出风风道263与容纳腔261的上部连通，以使得进风风道262、上述中间风道和出风风道263共同形成上下贯穿的散热风道。也就是说，出风风道263、容纳腔261和进风风道262从上至下依次连接。由此，散热风道可与环境空间之间形成空气流循环，显示控制组件30产生的热量可通过该散热风道散发出去，避免了热量囤积，从而降低了显示控制组件30周围的温度，减小了显示控制组件30所处空间的发泡侧(可认为是容易产生冷量的冷侧)与显示控制组件侧(可认为是容易产生热量的热侧)之间的温差，减少甚至避免该空间内出现冷热交界现象，进而进一步避免显示控制组件(尤其是显示控制 组件30的背部及其触摸显示屏)上产生凝露。
在本发明的一些实施例中，面板10可以为整体透明的玻璃面板。在本发明的一些替代性实施例中，面板10也可以为具有透明窗口的非透明面板，显示控制组件30正对该非透明面板的透明窗口。显示控制组件30可通过胶黏的方式预先固定在面板10的后向表面，然后再将固定有显示控制组件30的面板10装配至门体发泡组件20上，从而完成门体1的装配。此种装配顺序不但能够简单地实现门体发泡组件20的定位，而且可减小甚至消除显示控制组件30的触摸显示屏与面板10之间的间隙，从而提高触摸效果，进一步防止触摸显示屏上产生凝露。更具体地，面板10的后向表面可设有具有滑动筋的安装支架，面板10可通过其安装支架从上往下地安装至门体发泡组件20，安装过程简单，操作简便，并且便于后续对显示控制组件30进行拆卸维修或更换。
在本发明的一些实施例中，参见图3，进风风道262内设有进风风机50，进风风机50配置成在显示控制组件30所处空间内的湿度达到预设的第二湿度阈值时受控地启动，以促使环境空气经进风风道262流向容纳腔261。也就是说，进风风机50能够加速显示控制组件30所处空间与环境空间之间的空气流动，不但能够更加有效地带走显示控制组件30所产生的热量，而且还能够通过空气的加速流通产生明显的防凝露效果。
进一步地，门体1还包括湿度传感器，其可以安装在显示控制组件30所处的空间内，以直接获取该空间内的湿度。湿度传感器还可以安装在门体1的外部，例如安装在门体1上部的铰链盒内，以通过直接获取门体1所处环境空间的湿度，从而间接获得显示控制组件30所处空间内的湿度。
本领域技术人员应理解，本发明实施例中所称的第二湿度阈值可以是用户或设计人员根据实际情况或实验结果而自行设定的湿度值，该湿度值通常用相对湿度值来表示，例如第二湿度阈值可以为60％、70％或80％。
在本发明的一些实施例中，进风风机50为前侧与面板10之间留有间隙的离心风机，该离心风机具有朝向前侧的进风口和朝向容纳腔261的出风口。离心风机的压损小，送风效率较高，因此能够提高散热效果。
进一步地，前门衬21还具有由容纳腔261的后壁进一步向后凹进的安装部，至少进风风机50的后侧部分安装支撑在该安装部中。
图4是根据本发明一个实施例的门体的另一方位示意性结构图，图5是 根据本发明一个实施例的门体的又一方位示意性结构图。在本发明的一些实施例中，参见图4和图5，上饰条23和下饰条24上可分别开设有与出风风道263连通的出风口231和与进风风道262连通的进风口241。出风口231的数量可以与子风道2631的数量相同，即每个子风道2631均对应一个出风口231。进风口241的数量可以为一个，其宽度小于等于进风风道262下端的宽度。进风口241的数量也可以为多个，多个进风口241均匀分布。
图6是根据本发明一个实施例的用于冷藏冷冻装置的门体的另一示意性结构分解图。在本发明的一些实施例中，参见图6，门体发泡组件20内埋置有加热装置40，加热装置40配置成在显示控制组件30所处空间内的湿度达到预设的第一湿度阈值时受控地启动，并向门体发泡组件20的前部提供热量。由此，可在显示控制组件30所处空间内的湿度达到预设的第一湿度阈值时通过加热装置40适当地提高门体发泡组件20前部的温度，以减小显示控制组件30所处空间的发泡侧(可认为是容易产生冷量的冷侧)与显示控制组件侧(可认为是容易产生热量的热侧)之间的温差，从而减少甚至避免该空间内出现冷热交界现象，进而避免显示控制组件30(尤其是显示控制组件30的触摸显示屏)上产生凝露。同样地，这里所说的第一湿度阈值也可以是用户或设计人员根据实际情况或实验结果而自行设定的湿度值，其取值可以与第二湿度阈值的取值相同，也可以与第二湿度阈值的取值不同。
进一步地，加热装置40可设置于前门衬21的后向表面，以直接向前门衬21提供热量。由此，可适当提高前门衬21的温度，减小前门衬21与显示控制组件30之间的温差，从而避免产生凝露。
更进一步地，加热装置40的发热区段可均匀地分布在前门衬21后向表面的位于显示控制组件30正后方的区域内，以仅向前门衬21后向表面的与显示控制组件30前后相对的区域提供热量，避免热量传递至面板10或其他不需要热量的区域。同时，加热装置40的发热区段均匀布置，可使得显示控制组件30所处的整个空间内的温度更加均衡，避免局部区域产生凝露。
具体地，加热装置40可以为贴附于前门衬21后向表面的铂片式加热丝，其占用空间较小，安装方便。该铂片式加热丝以S形的布局方式贴附在前门衬21的后向表面。
大量实验证明，本发明的门体1通过加热装置40、散热风道、进风风机50以及多个子风道2631等多个方面的特别设计的相互配合和共同作用，能 够起到良好的防凝露效果。需要特别指出的是，本发明门体1的特别设计尤其适用于具有较大显示屏屏幕的门体(即大屏门体)，特别适用于具有较大显示屏屏幕的复式门体。
本发明还提供一种冷藏冷冻装置，图7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。本发明的冷藏冷冻装置3包括：箱体2，其内限定有用于存放物品的储物空间；以及上述任一实施例中的门体1。门体1直接或间接地连接于箱体2，以打开和/或关闭至少部分储物空间。
具体地，冷藏冷冻装置3包括但不限于普通或通俗意义上的冰箱，还包括冰柜、冷柜等常见的装置，也包括其他具有冷藏和/或冷冻功能的装置。以冰箱为例，冷藏冷冻装置3可以为单门冰箱，也可以为多门冰箱，例如对开门冰箱。当冷藏冷冻装置3为多门冰箱时，门体1可以为其中任意一个门体。
本发明实施例所涉及的冷藏冷冻装置3可具有压缩制冷系统、半导体制冷系统或其他合适的制冷系统，以为其箱体2内的储物空间提供冷量，从而使该储物空间保持冷藏、冷冻或其他特殊条件的储存环境。
本领域技术人员还应理解，本发明实施例中所称的“上”、“下”、“竖”、“横”、“前”、“后”等用于表示方位或位置关系的用语是以门体1和冷藏冷冻装置3的实际使用状态为基准而言的，这些用语仅是为了便于描述和理解本发明的技术方案，而不是指示或暗示所指的装置或部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发明的限制。
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。
