技术领域
本发明涉及烹饪技术领域，特别涉及嵌入式烹饪器具及烹饪系统。
背景技术
现有技术中的一些烹饪器具采用嵌入的方式，包括半嵌入式和全嵌入式，然而无论半嵌入式或者全嵌入式的烹饪器具，都需要用户在橱柜后侧增加相应专门的通风风道，以满足设备散热需要，造成用户需要事先在橱柜上切割出专门的通风口，过程繁锁复杂，造成成本高且安装麻烦。现有的嵌入式安装的烹饪器具的风道都是单一风道(冷风或热风),或没有明确的风道来实现烹饪器具内部及厨柜冷却、散热通风，造成冷却效果不佳，存在安全隐患。
同时，现有的嵌入安装于橱柜的嵌入式烹饪器具，其散热时通常采用热风设备将嵌入式烹饪器具内部的热风，通过很短的出风通道从嵌入式烹饪器具的正面直接排出厨柜，然而上述出风结构容易产生两个问题，一是对于嵌入式的嵌入式烹饪器具，由于将热风直接排出至厨房，使得出风口容易出现温度过高的现象，从而可能对用户造成伤害；二是将热风直接排出至厨房，热风含有的大量能量没有得到利用，造成能量的损失，使用不够节能。

随着人们生活水平的逐步提高，清洁美观的整体式橱柜逐渐走进了千家万户的厨房，作为厨房的常用烹饪炉具，原有的微波炉、烤箱等烹饪器具嵌入在整体式橱柜内，从而大大提高了厨房内空间的占用率，并提高了厨房的美观性。
现有的嵌入式安装的烹饪器具的出风通道是通过热风设备强制直接排出橱柜，容易造成三个方面的问题，一是直接将热风排出在厨房，在出风口处容易出现温度过高，可能造成人员伤害；二是要求安装时需要在橱柜是增加专门的通风风道；三是造成能量损失，不节能。
下面参照说明书附图1至6，说明本发明实施例的烹饪系统和嵌入式烹饪器具。
参照图1所示，本发明一些实施例的烹饪系统，包括本发明第一方面实施例的嵌入式烹饪器具和橱柜101，其中，橱柜101设置有安装孔102，嵌入式烹饪器具安装在橱柜101的安装孔102内，安装孔102的前方预留有开口(图中未示出)，其余的面上均可以封闭。嵌入式烹饪器具包括壳体103、门体104、腔体105和风机106，门体104安装在壳体103上，腔体105和风机106设置在壳体103内。需要说明的是，图中的箭头表示空气的流动方向。
参照图1和图2所示，可以理解的是，壳体103的底部设置有凹凸结构107，即壳体103的底部设置有凹槽或者凸起。从而当嵌入式烹饪器具安装在橱柜101的安装孔102内时，嵌入式烹饪器具的底部与橱柜101的安装孔102底面之间形成有允许空气流动的通道，外界的空气可以从该通道中流入到安装孔102内。另外，嵌入式烹饪器具在安装的时候，一般都会使嵌入式烹饪器具的后部与橱柜101的安装孔102后壁之间留有空隙。可以理解的是，外界的空气从嵌入式烹饪器具的底部与橱柜101的安装孔102底面之间的通道流进安装孔102内后，还可以进入嵌入式烹饪器具的后部与橱柜101的安装孔102后壁之间的空隙中，即壳体103的底部和壳体103的后方形成流通空气的进风空间。外界的空气能够对嵌入式烹饪器的壳体103外表面以及橱柜101的安装孔102内壁同时进行冷却，提高冷却效果。
参照图1所示，可以理解的是，壳体103内设置有电器室108，电器室108内安装有磁控管109、电子变压器402和发热管301等电器元件，壳体103设置有连通进气空间和电器室108的第一进气口110，从而使得外界的空气能够进入电器室108内，对电器室108内的磁控管109、电子变压器402和发热管301等电器元件进行冷却。
参照图1所示，可以理解的是，壳体103包括前板302，前板302设置有连通外界空气和所述电器室108的第二进气口117，从第一进气口110和第二进气口117进入的空气，在电器室108汇合后，对电器室108内的磁控管109、电子变压器402和发热管301等电器元件进行冷却。通过设置第二进气口117，从而增加一条进气的通道，增大进风量，从而有效提高散热效果。
参照图1所示，可以理解的是，风机106设置在电器室108内。风机106将外界的空气吸进电器室108内，从而加快空气流动，提高对电器室108内的电器元件的冷却效率。
参照图1所示，可以理解的是，风机106设置在电器室108内靠近第一进气口110的一侧。现有产品通常采用风机106后置的结构，这样设计风机106和产品进风口的距离过大，以致产品进风口位置产生的负压较低，吸入空气量少，无法对电器件进行充分冷却。而本方案中，风机106的位置靠近连通进气空间和电器室108的第一进气口110，大幅缩短了风机106与第一进气口110的距离，从而可增大壳体103第一进气口110处的位置负压，提高进风量，进而提升产品的散热效果。
参照图1所示，可以理解的是，腔体105设置在壳体103内，腔体105设有烹饪腔111，腔体105设置有连通电器室108和烹饪腔111的进风口112，通过进风口112，可以将电器室108内的空气吹进烹饪腔111内，从而加快空气流动，对烹饪腔111进行散热，在此过程中，空气会将烹饪腔111中的一部分热量一起带走，从而能够实现对烹饪腔111降温的效果，进而可以缓解烹饪腔111内温度过高的问题。
参照图1和图2所示，可以理解的是，壳体103内设置有出风通道113，壳体103设置有连通出风通道113的出气口201，腔体105设置有连通出风通道113的第一出风口114。 风机106启动，将外界的空气吸进嵌入式烹饪器具的底部和壳体103的后方形成的进风空间中，然后通过第一进气口110进入电器室108内，对电器室108内的磁控管109、电子变压器402和发热管301等电器元件进行冷却，再通过进风口112进入烹饪腔111中，并经由第一出风口114进入出风通道113，最后从出气口201排出，完成散热过程。在散热过程中，外界的空气流经进风空间对嵌入式烹饪器的壳体103外部进行冷却，同时流经电器室108和烹饪腔111对嵌入式烹饪器的内部进行冷却，全面提升冷却效果。
通过在壳体103的底部设置有凹凸结构107，使得壳体103的底部能够流入外界空气并且进入到壳体103的后方，即壳体103的底部和壳体103的后方形成流通空气的进风空间，空气从进风空间进入到嵌入式烹饪器具中进行冷却，将嵌入式烹饪器具在烹饪过程中产生的热量导出嵌入式烹饪器具、橱柜101，从而保护嵌入式烹饪器具、橱柜101安全。同时，凹凸结构107和出风通道113等结构都设置在嵌入式烹饪器具上，进风和出风不需要对橱柜101进行改造，避免因需要事先在橱柜101增加专门的通风通道，减少工作量并降低安装成本。同时，从壳体103的底部至第一进气口110，限定出第一进风通道，从第二进气口117到电器室108限定出第二进风通道，从而形成双通道的结构，有效提高进风量，从而达到提高冷却降温的效果。
参照图1和图2所示，可以理解的是，壳体103包括前板302，前板302上设有开口(图中未示出)，门体104安装在前板302的前表面上，用于控制前板302的开口开闭，出气口201设置在前板302的下部，嵌入式烹饪器具还包括控制组件115，控制组件115安装在前板302的上部，用户通过控制组件115控制嵌入式烹饪器具的启动、关闭和功能选择等工作。
传统的嵌入式烹饪器具通常由控制组件115与门体104间的间隙出风，导致控制组件115位置有热风吹出，影响用户使用产品的感受。而本方案提供的嵌入式烹饪器具由前板302的下部出风，使出风位置远离控制组件115，以保证用户对控制组件115进行操作时减少与热风的接触，从而提升用户的使用感受。
参照图3和图4所示，可以理解的是，嵌入式烹饪器具还包括发热管301，发热管301用于对烹饪腔111内的食物进行加热。
可以理解的是，嵌入式烹饪器具还包括热风电机(图中未示出)，热风电机的输出轴相连有热风扇叶(图中未示出)，热风扇叶转动带动空气流动，气流与发热管301接触并带有发热管301发出的热量，从而形成高温的热风。热风使得烹饪腔111内的食物受热更加均匀，提高加热的效果。壳体103内设置有连通进气空间的热内室(图中未示出)，热风电机设置在热内室内。通过将热内室与进气空间进行连通，使得进气空间的空气能够进入到热内室中对热风电机进行散热，保证热风电机正常运行，提高热风电机的使用寿命。即外界空气进入进风空间后，一路沿第一进气口110进入电器室108，另一路则进入热内室对热风电机进行散热，增强对嵌入式烹饪器具的散热效果。
参照图3和图4所示，可以理解的是，壳体103包括前板302、后板303、左外罩304、右外罩305和上外罩306，腔体105包括顶板308，顶板308与上外罩306、部分前板302、部分后板303、部分左外罩304和部分右外罩305限定出了电器室108，磁控管109、电子变压器402和发热管301等电器元件安装在腔体105的顶板308上。
参照图4所示，可以理解的是，出风通道113位于腔体105的侧面，如此能够让流出的热风尽可能远离其他电器元件和控制组件115，避免影响其他电器元件和控制组件115 的散热效果，并且有效利用腔体105两侧的空间，提高空间利用率。
参照图4所示，可以理解的是，嵌入式烹饪器具还包括炉灯401，炉灯401设置在出风通道113内。炉灯401主要起照明作用，但是炉灯401的温度相对较高，造成炉灯401容易损坏。而本实施例中，通过将炉灯401设置在出风通道113内，可以让流出的气流带走炉灯401的部分热量，从而降低炉灯401的温度，实现对炉灯401的降温，提高炉灯401的使用寿命。
参照图1、图3和图4所示，可以理解的是，电器室108设置有罩设于进风口112的导风罩116，导风罩116远离进风口112的一侧设置有入风口，风机106设置在入风口外并将外界的空气引入导风罩116内部。通过设置导风罩116引导气流流向进风口112，使得气流更加集中，提高冷却效率，利用效率更高。
参照图3和图4所示，可以理解的是，导风罩116设有凹部309，凹部309降低了导风罩116的高度，从而减少导风罩116对空气的阻挡，增大第一进气口110和第二进气口117之间的流通风量。
参照图1、图3和图4所示，可以理解的是，嵌入式烹饪器具利用电能通过磁控管109产生超短波，并把超短波照射在食物等被加热物上，实现对食物的烹饪。磁控管109设置在导风罩116内，导风罩116可以集中气流对磁控管109进行冷却，加快磁控管109的冷却效率。在嵌入式烹饪器具的使用过程中，磁控管109和电子变压器402会产生较多的热量，而嵌入式烹饪器具的其他电器元件，例如电脑板(图中未示出)和滤波板(图中未示出)对温升控制要求较高，出现温升超标的问题会影响产品运行的可靠性。为此本方案通过导风罩116将磁控管109、电子变压器402与电脑板、滤波板等电器元件分隔开，能够大幅减少磁控管109向电脑板和滤波板所在的区域传递热量，因此可大幅降低电脑板和滤波板的温升，从而保证产品运行的可靠性。
参照图1、图3和图4所示，可以理解的是，导风罩116设置有渐变部307，所述渐变部307的横截面积沿靠近所述进风口112的方向逐渐减小，渐变部307位于进风口112的上方。具体的，渐变部307由靠近风机106的一侧朝向进风口112的一侧倾斜向下，从而使得热风由电器室108内靠近风机106的一侧流向电器室108内靠近进风口112的一侧时，在倾斜向下的渐变部307的作用下，热风可以更为顺畅地进入进风口112从而进入烹饪腔111中。
参照图5所示，可以理解的是，第一出风口114设置在腔体105的侧面，并且第一出风口114可以设置有多个，并且分为两组，两组第一出风口114分别位于腔体105的一侧的两边，通过设置多个第一出风口114，从而可以增加出风通道113与烹饪腔111的连通面积，同时还尽可能减小对腔体105的强度影响，提高出风效率，使得热风从烹饪腔111排出至出风通道113时更顺畅。
参照图5所示，可以理解的是，出气口201可以设置有多个，多个出气口201间隔分布于前板302的下端。出气口201的形状可以根据实际需要而具体设置，例如可以是圆形或椭圆形或多边形或是其他形状。通过在前板302的下端间隔分布设置多个出气口201，从而可以增加出风通道113与外界空间的连通口的数量，提高出风通道113的出风效率，使得热风从出风通道113排出至嵌入式烹饪器具外部时更顺畅。
本发明的第二方面实施例提供了一种嵌入式烹饪器具，参照图1至图4，该嵌入式烹饪器具嵌入安装于橱柜101中，嵌入式烹饪器具可以是微波炉或烤箱或蒸烤箱或是其他形 式的嵌入式烹饪器具。嵌入式烹饪器具包括腔体105和壳体103，腔体105内部形成有烹饪腔111，烹饪腔111用于放置食物，腔体105的上侧安装有导风罩116，导风罩116与腔体105的上侧之间围设形成有电器室108，电器室108安装有磁控管、电子变压器等磁控管109，磁控管109工作时会产生大量的热量，使得电器室108内的温度可以达到350℃以上。腔体105的上侧设置有连通电器室108与烹饪腔111的进风口112，腔体105的上侧位于电器室108相对进风口112的另一侧安装有风机106，风机106可以是涡流风机或抽风风扇等组件，风机106用于驱动外界的空气进入电器室108，使得电器室108内的磁控管109可以得到降温，从而保持磁控管109稳定的工作，空气经过磁控管109的加热后形成热风，部分热风在导风罩116的作用下通过进风口112进入烹饪腔111，由于嵌入式烹饪器具工作时，烹饪腔111的温度一般为200℃左右，烹饪腔111内的温度相对电器室108内的温度较低，因此热风从电器室108进入烹饪腔111时，热风会对烹饪腔111起到辅助加热的作用，从而可以实现热风能量的充分利用，减少烹饪腔111加热至设定温度时嵌入式烹饪器具原本所需的热量，从而有利于提升嵌入式烹饪器具的节能效果。参照图1，壳体103罩设于腔体105的外侧，壳体103的上外罩306与腔体105的上侧之间形成有进风风道，腔体105的前侧通常安装有控制组件115和门体104，外界的空气可以通过控制组件115和门体104之间的间隙进入腔体105的前侧，然后通过腔体105前侧设有的穿孔进入进风风道内，然后经过风机106送入电器室108内。参照图1和图4，壳体103的底外罩310与腔体105的下侧之间形成有出风通道113，壳体103的左、右外罩304、305与腔体105的左、右侧之间形成有导风通道118，导风通道118与出风通道113连通，烹饪腔111设置有与导风通道118连通的第一出风口111，电器室108设置有与导风通道118连通的第二出风口121，电器室108的部分热风进入烹饪腔111对烹饪腔111进行加热后，通过第一出风口111排入导风通道118，电器室108的另一部分热风通过第二出风口121排入导风通道118，两部分热风在导风通道118汇合，然后再进入出风通道113，最后排出嵌入式烹饪器具的外部。
参照图1，嵌入式烹饪器具工作时，风机106将外界的空气送入电器室108，外界空气对电器室108内的磁控管109进行散热后变成热风，在导风罩116的作用下，一部分热风通过进风口112进入烹饪腔111，进入烹饪腔111的热风对烹饪腔111进行辅助加热，实现热风能量的充分利用，有利于减少嵌入式烹饪器具的能耗，使得嵌入式烹饪器具更为节能，降低了嵌入式烹饪器具的使用成本，然后该部分热风从第一出风口111排出进入导风通道118，在导风罩116的作用下，另一部分热风通过第二出风口121进入导风通道118，两部分的热风在导风通道118汇合后进入出风通道113，延长了热风流动的距离，使得热风经过长距离的冷却后再排出嵌入式烹饪器具外部，有效降低了热风排出时的温度，避免高温度的热风直接排出可能导致的伤害，提高了嵌入式烹饪器具使用的安全性和舒适性。
参照图1和图6，上述实施例中，第一出风口111可以设置于烹饪腔111远离进风口112的一侧，从而使得热风从电器室108通过进风口112进入烹饪腔111后，可以从烹饪腔111的一侧流动至烹饪腔111的另一侧，增加热风在烹饪腔111内流动的路程，从而使得热风可以对烹饪腔111进行充分的加热，使得热风的能量可以充分释放出来，有利于更多地降低热风从第一出风口111进入导风通道118时的温度，从而使得热风最终排出嵌入式烹饪器具时，热风的温度可以降到更低，进一步有利于避免热风排出时可能造成的伤害。
参照图1、图5和图6，具体的，腔体105的左、右侧开设有呈阵列布置的通孔，通 孔构成第一出风口111，通孔的数量和孔径可以根据实际需要而具体设置。烹饪腔111内的热风通过腔体105左、右侧阵列布置的通孔，从而可以快速进入腔体105左、右侧外部的导风通道118中，然后再从出风通道113排出至嵌入式烹饪器具的外部，大大提高了热风从烹饪腔111内排出的效率。
参照图1、图3和图4，在一些实施例中，腔体105的上侧安装有支撑板119，支撑板119延伸至导风通道118的上方，导风罩116罩设于部分支撑板119的上方，电器室108由导风罩116与部分支撑板119以及腔体105的上侧围设而成，磁控管109可以方便地安装于支撑板119上，避免磁控管109直接安装于腔体105上侧造成腔体105容易损坏。支撑板119位于导风通道118的上方开设有缺口，缺口构成第二出风口121，缺口的形状可以是圆形或多边形或是椭圆形或是其他形状，缺口的形状和大小可以根据实际需要而具体设置，电器室108内的部分热风通过缺口可以快速进入导风通道118，然后再经过出风通道113排出嵌入式烹饪器具的外部。
参照图1和图4，具体的，第二出风口121与进风口112间隔设置于电器室108远离风机106的一侧，嵌入式烹饪器具工作时，风机106将外界的空气送入电器室108的一侧，然后空气从电器室108的一侧向电器室108的另一侧流动时，空气不断对电器室108内的磁控管109进行散热从而变成热风，最后热风从电器室108另一侧的进风口112和第二出风口121排出电器室108的外部，使得空气在电器室108内的流动过程中对磁控管109的散热更为充分，提高散热的效率。
参照图1和图4，上述实施例中，导风罩116还具有渐变部307，渐变部307对电器室108内空气的流动起到导向的作用。具体的，渐变部307由靠近风机106的一侧朝向第二出风口121的一侧倾斜向下，从而使得热风由电器室108内靠近风机106的一侧流向电器室108内靠近第二出风口121的一侧时，在倾斜向下的渐变部307的作用下，热风可以更为顺畅地进入第二出风口121从而进入导风通道118中。由于进风口112和第二出风口121同样设置于电器室108远离风机106的一侧，因此在渐变部307的作用下，部分热风进入进风口112而进入烹饪腔111中，另一部分热风进入第二出风口121而进入导风通道118中。
参照图2和图5，在一些实施例中，腔体105的前侧设置有前板302，前板302的下端设置有出气口201，出气口201与出风通道113连通，从而使得热风经过导风通道118和出风通道113充分冷却降温后，从腔体105前板302的出气口201排出，使得出风更为顺畅，而且嵌入式烹饪器具的控制组件115通常设置于腔体105前板302的上端，因此用户操作控制组件115时，热风从腔体105前板302的下端排出，可以减少对用户的影响，提高使用的舒适性。当然，在另一些实施例中，可以在橱柜101开设有橱柜101风道，出风通道113和/或导风通道118与橱柜101风道连通，此时热风通过橱柜101风道排出外界，可以进一步避免热风从嵌入式烹饪器具的正面排出对人体的影响，进一步提高该嵌入式烹饪器具使用的舒适性。
参照图5，具体的，出气口201可以设置有多个，多个出气口201间隔分布于前板302的下端。出气口201的形状可以根据实际需要而具体设置，例如可以是圆形或椭圆形或多边形或是其他形状。通过在前板302的下端间隔分布设置多个出气口201，从而可以增加出风通道113与外界空间的连通口的数量，提高出风通道113的出风效率，使得热风从出风通道113排出至嵌入式烹饪器具外部时更顺畅。
参照图2，上述实施例中，壳体103的下侧设置有导风件120，导风件120由前板302的下端朝向远离前板302的一侧延伸。通过如上设置，使得从出气口201排出的热风在导风件120的导向作用下，热风可以更远的导出至嵌入式烹饪器具的外部，避免热风在出气口201附近积聚而降低出风的效果。导风件120下端与橱柜101之间还具有空隙，外界空气可以通过该空隙进入壳体103底外罩310与橱柜101之间的通道，然后通过壳体103后部开设的通孔进入腔体105上侧与壳体103上外罩306之间的空间，从而在风机106的作用下进入电器室108内对磁控管109进行散热，有利于提高风机106的进风量，进一步提高磁控管109散热的效果。
参照图1所示，可以理解的是，本发明第三方面实施例的烹饪系统，包括橱柜101以及本发明第一方面实施例的嵌入式烹饪器具，嵌入式烹饪器具安装在橱柜101内。由于采用了本发明的第一方面实施例的嵌入式烹饪器具，能够将嵌入式烹饪器具在烹饪过程中产生的热量导出嵌入式烹饪器具、橱柜101，从而保护嵌入式烹饪器具、橱柜101安全，同时也避免因需要事先在橱柜101增加专门通风通道，减少工作量并降低安装成本。
参照图1，本发明第四方面实施例的烹饪系统，包括橱柜101以及本发明第二方面实施例的嵌入式烹饪器具。橱柜101设置有安装孔102，嵌入式烹饪器具嵌入安装于安装孔102内。烹饪系统工作时，嵌入式烹饪器具的风机106将外界的空气送入电器室108，外界空气对电器室108内的磁控管109进行散热后变成热风，在导风罩116的作用下，一部分热风通过进风口112进入烹饪腔111，进入烹饪腔111的热风对烹饪腔111进行辅助加热，实现热风能量的充分利用，有利于减少嵌入式烹饪器具的能耗，使得嵌入式烹饪器具更为节能，降低了嵌入式烹饪器具的使用成本，然后该部分热风从第一出风口111排出进入导风通道118，在导风罩116的作用下，另一部分热风通过第二出风口121进入导风通道118，两部分的热风在导风通道118汇合后进入出风通道113，延长了热风流动的距离，使得热风经过长距离的冷却后再排出嵌入式烹饪器具外部，有效降低了热风排出时的温度，避免高温度的热风直接排出可能导致的伤害，提高了烹饪系统使用的安全性和舒适性。
上面结合附图对本发明实施例作了详细说明，但是本发明不限于上述实施例，在所属技术领域普通技术人员所具备的知识范围内，还可以在不脱离本发明宗旨的前提下作出各种变化。
