具体实施方式
以下结合附图对本发明的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明，并不用于限制本发明。
需要说明的是，在不冲突的情况下，本发明中的实施例及实施例中的特征可以相互组合。
在本发明中，在未作相反说明的情况下，使用的方位词如“上、下、顶、底”通常是针对附图所示的方向而言的或者是针对竖直、垂直或重力方向上而言的各部件相互位置关系描述用词。
下面将参考附图并结合实施例来详细说明本发明。
本发明提供了一种冷热一体装置100，如图1至图14所示，该冷热一体装置100包括底座3、设置在底座3的一端的制热部1以及设置在底座3的另一端的制冷部2。其中，制热部1包括用于制热的热壶11，热壶11可以是电热水壶或养生壶等加热容器，制冷部2包括用于对液体制冷的冷壶21，此处的制冷功能不限于制冷水功能，还可包括制冰功能或对热水进行降温的功能。
需要说明的是，制冷部2可设置为单独的小家电制冷装置。当制冷部2为单独的小家电制冷装置时，该小家电制冷装置可包括底座3和设置在底座3上的所有制冷部2中的部件。当制冷部2为上述冷热一体装置100的组成部分时，制热部1和制冷部2能够设置在同一底座3上以简化结构。
此外，冷热一体装置100可包括食品加工装置，该食品加工装置可具备一种或多种的食品处理功能，例如搅拌功能或榨汁功能等。对于冷热一体装置100而言，在设有制冷部2的前提下，底座3上可设置能够独立于制冷部2工作的制热部1或食品加工装置，或同时设置制热部1和食品加工装置。当然，食品加工装置也可设置为自带加热功能。
可见，本发明的冷热一体装置100中的制热部1和制冷部2是能够相互独立工作的，包括热壶11和冷壶21同时工作或单独工作。因此，该冷热一体装置100能够适应不同人群的饮水习惯，提高用户的使用便利性，从而大大提升用户的使用体验。
具体地，制冷部2可包括设置在底座3的顶壁上的冷壶插装槽24，冷壶21插装在冷壶插装槽24中，制热部1可包括设置在底座3的顶壁上的热壶插装槽12，热壶11容置于热壶插装槽12中。
为保证制热部1与制冷部2之间相互独立，冷壶插装槽24与热壶插装槽12优选间隔设置。此外，由于热壶11和冷壶21的类型不限，在一些实施方式中，热壶11和冷壶21可分别固定插装在热壶插装槽12和冷壶插装槽24中，或者热壶11和冷壶21均设置为可供用户拿取的结构，又或者是设置为热壶11和冷壶21中的一者固定插装而另一者可拿取的结构。因此，本发明的冷热一体装置100除了能够适应不同人群的饮水习惯之外，还能够适应不同的用户使用习惯。
在一些实施方式中，为保证冷壶21能够稳定插装，可在冷壶插装槽24中安装导冷套筒22，该导冷套筒22的内径比冷壶21的冷壶内胆21c的外径略大。因此，当冷壶内胆21c至少部分插装在导冷套筒22的套筒腔中时，冷壶内胆21c不会出现晃动的情况，具有稳定的安装结构。
此外，由于导冷套筒22具有导冷特性，其可作为冷壶21与制冷系统之间的导冷结构。但为了使导冷效率更高，可在导冷套筒22的套筒内壁与冷壶内胆21c的内胆外壁之间填充导冷介质。
在一些实施方式中，可在冷壶插装槽24中设置隔热保温层23，以使得对冷壶21的隔热保温效果更好。例如，隔热保温层23可设置在导冷套筒22的套筒外壁与插装槽的内壁之间，隔热保温层23可形成为真空保温层或填充有隔热保温介质。
在一些实施方式中，热壶11的热壶内腔和/或冷壶21的冷壶内腔中设有搅拌装置。当热壶11中设有搅拌装置时，制热部1中相当于具有食物料理机的功能。而当冷壶21中设有搅拌装置时，该搅拌装置配合冷壶21的制冰功能，能够制出口感较佳的冰沙。
在一些实施方式中，制热部1可包括用于调控热壶11的温度的热壶温度调节装置，制冷部2可包括用于调控冷壶21的温度的冷壶温度调节装置。通过设置温度调节装置，用户能够根据自身的饮水要求来制取具有特定温度的开水。进一步地，制热部1可包括过热保护装置，制冷部2可包括过冷保护装置，能够保证冷热一体装置100的安全使用。
在一些实施方式中，热壶插装槽12的插装槽内壁上设有沿周向依次间隔排布的多个插装槽功能键位，每个插装槽功能键位对应热壶11的不同使用功能，热壶11的外壁上设有功能选择键位。当用户将热壶11相对热壶插装槽12旋转时，功能选择键位能够对准任意的插装槽功能键位，功能选择键位与插装槽功能键位对准时实现电连接，从而使热壶11实现该插装槽功能键位对应的功能。
可选地，制冷部2可通过热电制冷系统实现制冷，该热电制冷系统包括半导体制冷片215和用于对半导体制冷片215供电的供电电路，底座内腔中可设有电控板10，供电电路可集成在电控板10中。其中，半导体制冷片215包括制热端面和用于对冷壶内胆21c的外壁制冷的制冷端面。
在一种实施方式中，制冷端面贴合安装于冷壶内胆21c的内胆外底壁，此时制热端面的下方连接有散热片216，以此确保半导体制冷片215的制冷端面能够持续制冷，否则，制热端面与制冷端面会达到热平衡，从而导致制冷端面的导冷效果减弱。
进一步地，冷热一体装置100还包括设置在底座3的底座内腔中的内散热风扇4，能够将散热片216的热量加速排出底座3外，进而保证制冷端面的高效制冷。
基于上述结构，为提高散热效率，可在底座3的底壁上开设散热孔，并且该散热孔优选设置在内散热风扇4的下方。更可选地，散热孔的轴向投影面积不小于内散热风扇的轴向投影面积，从而增大散热出风量，提高散热效率。
具体地，冷壶21包括套设在冷壶内胆21c外的冷壶外壳21a，并且冷壶内胆21c的外周壁与冷壶外壳21a的内周壁之间设有作为隔热保温层23的壶身保温层，保证对冷壶21的持续隔热保温。其中，该壶身保温层可设置为真空保温层或填充有相变制冷介质。
此外，冷壶21还包括用于盖合冷壶内胆21c的冷壶盖21b。该冷壶盖21b中设有作为隔热保温层23的壶盖保温层，并且冷壶盖21b的外壳体优选设置为密封外壳体，以此隔水隔热。
可选地，制冷部2包括设置在冷壶21与半导体制冷片215的制冷端面之间的导冷结构。其中，导冷结构中设有制冷片安装平面217，半导体制冷片215的制冷端面贴合安装在该制冷片安装平面217上，从而增大制冷端面的导冷面积，有利于提高制冷效率。
在一种实施方式中，参照图6至图9，导冷结构包括安装在导冷套筒22的外周壁上的独立导 冷元件218。此时，制冷片安装平面217设置在该独立导冷元件218上。可见，由于独立导冷元件218为能够独立于导冷套筒22生产的导冷部件，因此生产效率较高，并且易于装配和更换，能够降低生产成本和维修成本。
具体地，独立导冷元件218呈环箍状且包括环向的内导冷壁面218a和外导冷壁面218b，并且导冷套筒22为圆形套筒。此时，内导冷壁面218a与导冷套筒22的套筒外周壁面相互贴合，有利于增加导冷面积。此外，外导冷壁面218b上形成有制冷片安装平面217，能够供半导体制冷片215的制冷端面平整贴合。
进一步地，外导冷壁面218b上形成有外凸的导冷壁外凸部218c，导冷壁外凸部218c的径向外端面形成为制冷片安装平面217。或者，外导冷壁面218b上也可形成有内凹的导冷壁凹槽，该导冷壁凹槽的凹槽底壁可作为制冷片安装平面217，并且导冷壁凹槽的凹槽上侧壁和凹槽下侧壁能够分别抵接在半导体制冷片215的上下两端，保证其安装牢固。
此外，还可通过增大内导冷壁面218a与导冷套筒22的套筒外周壁面的环向接触面积和轴向接触面积来提高导冷效率。可选地，内导冷壁面218a的环向周长至少为套筒外周壁面的环向周长的一半，内导冷壁面218a的轴向长度至少为套筒外周壁面的轴向长度的1/3。
当内导冷壁面218a的环向周长大于等于套筒外周壁面的环向周长的一半时，可以使内导冷壁面218a与套筒外周壁面之间形成过盈压接，从而固定独立导冷元件218与导冷套筒22的装配。或者，可将独立导冷元件218设置为弹性导冷元件以弹性箍紧导冷套筒22。
当内导冷壁面218a的环向周长小于套筒外周壁面的环向周长的一半时，独立导冷元件218可通过胶粘或紧固件等固定安装在导冷套筒22上。
在另一种实施方式中，参照图10和图11，导冷结构包括直接形成在导冷套筒22的套筒外周壁上的制冷片安装平面217，半导体制冷片215的制冷端面同样能够与该制冷片安装平面217平整贴合。
可选地，套筒外周壁上形成有竖向的平整壁面，该平整壁面可作为制冷片安装平面217。或者，套筒外周壁上形成有径向内凹的制冷片安装凹槽，制冷片安装凹槽的凹槽底壁面形成为制冷片安装平面217。此时，半导体制冷片215至少部分嵌入制冷片安装凹槽中，并且半导体制冷片215的上下两端分别抵接制冷片安装凹槽的凹槽上侧壁和凹槽下侧壁，从而保证半导体制冷片215的稳定安装。又或者，套筒外周壁上形成有外凸的套筒外凸部22d，套筒外凸部22d的径向外端面形成为制冷片安装平面217，此结构便于在半导体制冷片215的制热端面上设置散热片216。
可选地，导冷结构中的制冷片安装平面217的平面面积不小于制冷端面的平面面积，该结构有利于进一步增大制冷端面与制冷片安装平面217的导冷接触面积。
此外，制冷部2包括用于感测冷壶21的温度的冷壶感温探头。该冷壶感温探头可以是能够间接感测冷壶温度的外置感温探头，也可以是能够直接感测冷壶温度的内置感温探头。
通过设置冷壶感温探头，本发明的冷热一体装置100能够根据感测到的冷壶温度实现温度调控、过冷保护或用户提醒等功能，有利于丰富冷热一体装置100的功能，从而使用户具有更好的使 用体验。
在一种实施方式中，参照图12和图13，冷壶感温探头为设置在导冷套筒22的套筒外底壁和/或套筒外周壁上的外置感温探头221，从而实现对冷壶21的间接感温。由于外置感温探头221始终不会与冷壶21中的液体直接接触，因此该感测方式相对直接感温而言更加干净卫生，能够确保用户的饮用安全。
可选地，导冷套筒22的套筒外底壁形成有套筒底壁凹槽22e，冷壶内胆21c的内胆底壁形成有内胆底壁凹槽21d。其中，套筒底壁凹槽22e的凹槽壁向上嵌入内胆底壁凹槽21d中，外置感温探头221至少部分嵌入套筒底壁凹槽22e。通过将外置感温探头221嵌入套筒底壁凹槽22e中，探头与导冷套筒22之间的导冷面积更大，更有利于提高探头的感测精准性。
更可选地，本实施方式中的导冷套筒22的套筒内底壁与内胆底壁之间填充有导冷介质，并且外置感温探头221的顶端抵接于套筒底壁凹槽22e的凹槽顶壁。可见，外置感温探头221的顶端与套筒底壁凹槽22e的凹槽顶壁直接接触能够进一步提高探头的感测精准性，从而使冷热一体装置100的工作性能更可靠。
进一步地，嵌入套筒底壁凹槽22e中的外置感温探头221的外周壁与套筒底壁凹槽22e的凹槽侧壁相互抵接，使外置感温探头221的外周壁与套筒底壁凹槽22e的凹槽侧壁完全接触，导冷面积达到最大化，感测精准性也相应最高。
可选地，导冷套筒22的套筒外底壁可设有探头通过孔，此时，外置感温探头221的顶端穿过探头通过孔并抵接冷壶内胆21c的内胆底壁。与上述的感温结构相比，本优选结构中的外置感温探头221的顶端与冷壶内腔之间仅间隔有冷壶内胆21c的内胆底壁，由于省去一层导冷结构，本优选结构中的外置感温探头221的感温精准性相对更高。
在另一种实施方式中，参照图14，冷壶感温探头为设置在冷壶21的冷壶内胆21c中的内置感温探头220。可见，由于内置感温探头220能够直接接触冷壶内胆21c中的液体，因此该感测方式相对间接感温而言，感温精准度更高。
可选地，冷壶21包括用于盖合冷壶内胆21c的冷壶盖21b，内置感温探头220可安装在冷壶盖21b的底部。更可选地，冷壶盖21b的底壁形成有向下凸起的壶盖下凸部21e，内置感温探头220从壶盖下凸部21e向下伸出。此时，通过设置壶盖下凸部21，内置感温探头220与液体之间的接触面积更大，感温精准度进一步提高。
此外，冷壶盖21b中可形成有用于隔热保温以及可用于安装电控板10的壶盖中空夹层21f，并且该壶盖中空夹层21f优选设置为真空夹层或填充有隔热保温介质。相应地，冷壶盖21b的外壳体优选设置为密封外壳体，形成隔水隔热结构。
在上述设有冷壶感温探头的冷热一体装置100中，还包括设置在底座3上的控制面板，该控制面板包括显示面板，该显示面板用于显示探头感测到的冷壶温度，即具有提醒用户实时感测温度的功能。此外，控制面板包括温度设置按键，电控板10可配置为控制半导体制冷片215制冷直至冷壶21达到温度设置按键的设定温度值，而冷壶感温探头优选采用能够向电控板10发出感测温度信 号的电子式感温探头。
可选地，底座3的顶壁上形成有向上凸起的底座凸起部33，冷壶插装槽24位于底座凸起部33中，使得冷壶插装槽24的轴向尺寸更大，能够放置体积更大的冷壶21，增加一次性制冷水或制冰量。
可选地，底座凸起部33呈方形且设有散热进风口34和散热出风口35。为提高散热效率，可将散热进风口34与散热出风口35分别设置在底座凸起部33的相邻侧面上，使得散热进风口34与散热出风口35之间形成垂直风道，从而增大风压，加快散热速度。
此外，由于热壶插装槽12与冷壶插装槽24间隔设置，可优选将热壶插装槽12的插装槽外侧壁避让散热进风口34和散热出风口35设置，以免在散热进风口34或散热出风口35附近形成较大风阻而影响散热。
进一步地，散热进风口34优选设置为呈圆拱形，并且进风口中设有沿径向间隔地同心布置的多个圆拱形栅条，散热出风口35优选设置为呈矩形百叶窗状，即出风口中设有沿竖向间隔排布的多个直条形栅条。当散热进风口34呈圆拱形且散热出风口35呈矩形百叶窗状时，散热风道中的风阻较小，能够加快散热速度，提高散热效率。
为了与上述能够形成垂直风道的进出风口结构相匹配，设置在底座内腔中的散热风扇为离心式散热风扇。其中，散热进风口34连通离心式散热风扇的进风端，散热出风口35连通离心式散热风扇的出风端。换言之，当离心式散热风扇旋转时，空气经散热进风口34轴向流动至散热风扇的进风端，并沿径向从散热风扇的出风端流动至散热出风口35，从而形成风压较大的散热风道。
此外，可优选在底座3的底壁或侧壁上设置底座贯通孔，这样底座内腔中积聚的冷凝水能够通过该底座贯通孔外排，或者该底座贯通孔也可以用于辅助散热，或者该底座贯通孔能够同时用于供冷凝水外排和辅助散热。
可选地，底座3包括相互扣合的底座上扣合盖31和底座下扣合盖32，热壶插装槽12和冷壶插装槽24均设置在底座上扣合盖31上。将底座3设置为扣合盖结构的好处在于，便于底座内腔中的各部件的装配，例如制冷系统的部件或散热风扇等结构，有利于增加生产效率，降低生产成本，并能够便于后续的拆机维修保养。
此外，冷壶21可通过胶粘、卡扣或紧固件等方式插装固定在冷壶插装槽24中，提高冷壶21与冷壶插装槽24之间的装配稳定性。进一步地，冷壶21的外周部与冷壶插装槽24的内周壁之间设有密封元件，用于隔热防水，保证冷壶21的高效制冷。
在一些实施方式中，参照图14，制冷部2包括可拿取地设置在底座3上的便携式冷壶219。该便携式冷壶219能够便于用户出行时随身携带，尤其是在炎热的夏季能够极大满足用户的饮用要求，实用性较高。
可选地，便携式冷壶219包括上方拿握部219a和下方插装部219b，下方插装部219b插装于导冷套筒22的套筒腔中。可见，通过将便携式冷壶219划分为便于用户拿握的上方拿握部219a以及用于制冷的下方插装部219b，能够方便用户随时携带或制冷。
当便携式冷壶219制冷完成后，下方插装部219b的外周壁温度较低，不利于用户拿握。但由于上方拿握部219a与下方插装部219b之间能够相互导冷，因此需要在上方拿握部219a的外周壁设置作为隔热保温层23的壶身保温层，以避免用户在接触上方拿握部219a时手感不适。
为提高制冷效率，下方插装部219b可设置为呈圆筒状，导冷套筒22可设置为圆形套筒。其中，下方插装部219b的外壁与导冷套筒22的内壁之间形成导冷接触结构。例如，该导冷接触结构可以是覆盖在导冷套筒22的内壁上的导冷弹性元件，此时下方插装部219b的外壁与导冷弹性元件的内壁弹性压接。或者，该导冷接触结构可以是分别形成在下方插装部219b的外周壁与导冷套筒22的内周壁之间的相互配合的旋接螺纹，此时下方插装部219b与导冷套筒22通过旋转接合，并通过各自的周壁导冷。又或者，该导冷接触结构可以是设置在导冷套筒22的内壁上的活动磁条，当下方插装部219b插装于导冷套筒22的套筒腔时，活动磁条的内壁抵压下方插装部219b的外壁。
可见，通过在下方插装部219b的外壁与导冷套筒22的内壁之间设置导冷接触结构，有利于提高制冷效率，并能够同时对下方插装部219b进行限位，使便携式冷壶219与导冷套筒22之间的装配更加稳定。
当下方插装部219b的外壁与导冷套筒22的内壁之间存在较大间隙时，会导致导冷效果变差，进而影响制冷效率。因此，为保证高效制冷，可在导冷套筒22中设有微动开关，该微动开关设置为在下方插装部219b与导冷套筒22插装到位时被触发。或者，可在导冷套筒22中设有用于感测下方插装部219b与导冷套筒22插装到位的红外感测装置，当检测到插装不到位时，不允许制冷。需要说明的是，插装是否到位指的是下方插装部219b的外壁与导冷套筒22的内壁之间存在的间隙是否足够小，只有当间隙足够小或者下方插装部219b的外壁与导冷套筒22的内壁之间形成上述的导冷接触结构时，才能保证高效制冷。
此外，由于便携式冷壶219需要频繁地插拔使用，下方插装部219b的外壁为较易磨损部位。特此，可在下方插装部219b的外壁设置具有导冷特性的耐磨涂层，以提高便携式冷壶219的耐磨损度，保证其美观性。
可选地，便携式冷壶219包括冷壶盖21b，冷壶盖21b中设有作为隔热保温层23的壶盖保温层。当用户需要外带便携式冷壶219时，该隔热保温结构能够起到较长时间的保温作用。
另外，对于本发明的冷热一体装置100的制热部1，其包括用于对热壶加热的热壶加热元件13、设置在热壶插装槽12中的连接器14以及用于固定安装连接器14的连接器固定板15，从而保证制热部1能够实现制热功能。
以上结合附图详细描述了本发明的优选实施方式，但是，本发明并不限于上述实施方式中的具体细节，在本发明的技术构思范围内，可以对本发明的技术方案进行多种简单变型，这些简单变型均属于本发明的保护范围。
另外需要说明的是，在上述具体实施方式中所描述的各个具体技术特征，在不矛盾的情况下，可以通过任何合适的方式进行组合，为了避免不必要的重复，本发明对各种可能的组合方式不再另行说明。
此外，本发明的各种不同的实施方式之间也可以进行任意组合，只要其不违背本发明的思想，其同样应当视为本发明所公开的内容。
