具体实施方式
为了能够更清楚地理解本发明的上述目的、特征和优点，下面结合附图和具体实施方式对本发明进行进一步的详细描述。需要说明的是，在不冲突的情况下，本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本发明，但是，本发明还可以采用其他不同于在此描述的其他方式来实施，因此，本发明的保护范围并不限于下面公开的具体实施例的限制。
如图2至图12所示，其中，图2为本发明实施例所涉及的加热烹调器的示意图。图3为门体50打开状态下的立体图。如图2及图3所示，加热烹调器主要具备底座10，其内部可形成供电源板、磁控管、变频器等电器件安装的下电器室；圆筒形的腔体20，其设置于底座10，内部形成有供食物放置的加热腔34，加热腔34的一侧形成为供食物进出的开口；半圆筒形的门体50，其设置于腔体20上，用于封闭或打开加热腔34的开口；上盖70，其盖设于腔体20之上，内部可形成供风扇、语音控制模块等电器件安装的上电器室(未图示)。
在上述实施例中，优选地，如图6所示，下电器室内设置导风罩40；至少一个微动开关409，导风罩40的顶部对应微动开关409设有第三安装位408，至少一个微动开关409设于第三安装位408上。
在该实施例中，微动开关409用于控制烹调器内部电路的通断，在门体50关闭开口时，微动开关409控制加热烹调器的内部电路导通，实现加热烹调器的加热等功能；在门体50关闭开口时，微动开关409控制加热烹调器的内部电路自动断开，实现加热烹调器在打开门体后自动断电等功能，防止加热烹调器可能产生的微波泄漏，提高烹调器的安全系数。
进一步地，如图6和图9所示，导风罩40上形成适于气流流动的冷却风道；底部风扇74，设置于冷却风道上；导风罩40的顶部对应第三安装位408的位置处设有第二散热孔410，第二散热孔410构成冷却风道的至 少一部分；
其中，底部风扇74吹出的风沿冷却风道吹向第二散热孔410，且由第二散热孔410吹向至少一个微动开关409；或至少一个微动开关409产生的热量通过第二散热孔410进入冷却风道，并由底部风扇74抽出。
在该实施例中，第二散热孔410构成冷却风道的一部分，用于冷却微动开关409，该冷却风道将底部风扇吹出的风导向微动开关409；或将微动开关409产生的热量通过冷却风道导出。
在本实施例中，底座10可使加热烹调器稳定的置于台面上，其内部形成的下电器室用于安装微动开关409和导风罩40等结构；在加热烹调器工作过程中，其下电器室内的微动开关409等电器件在运行时会产生热量，致使下电器室内的温度逐渐升高，若下电器室内的温度过高会严重影响电器件的使用寿命，因此，在导风罩40上设置相配合的底部风扇74和冷却风道，利用冷却风道将底部风扇74吹出的风导向至至少一个微动开关409；或者将至少一个微动开关409产生的热量从冷却风道内抽出，实现电器件的快速冷却，减少由于下电器室内温度过高导致电器件损害，延长电器件的使用寿命，进而提高加热烹调器的使用寿命；并且，在保证烹调器的低噪音运行的前提下，通过调节底部风扇74的转速可以进一步提高电器件的冷却效率。
在上述实施例中，优选地，如图9所示，导风罩40上设有卡槽401，底部风扇74设于卡槽401上。
在该实施例中，底部风扇74通过卡槽401卡接在导风罩40上，实现底部风扇74与导风罩40的可拆卸连接，便于底部风扇74的更换和维护。
图4为本发明实施例所涉及的门体50及其导轨结构的组装图。图5为本发明实施例所涉及的门体50及其导轨结构的分解图。如图4及图5所示，门体50主要包括：形成为大致半圆筒形的外透视层51；与该外透视层51适配的、同样形成为大致半圆筒形的内透视层52；配置于外透视层51与内透视层52之间的、同样形成为大致半圆筒形的金属网孔层，其表面上形成众多通孔，以防止微波加热功能下微波由加热腔34通过外透视层51与内透视层52透射出来，其与外透视层51、内透视层52一同构成门面50a； 形成为大致圆环状的下侧可动导轨54，其用于从下侧固定上述外透视层51、内透视层52及金属网孔层形成的门面50a；下侧固定导轨55，用于从下侧和/或外侧支撑下侧可动导轨54，下侧固定导轨55上设有供下侧可动导轨54滑动的下侧凹槽552(参见图5)，下侧可动导轨54可滑动地设置于下侧凹槽552内；下侧可动导轨54可相对下侧固定导轨55滑动或通过两者之间设置的多个滚动件(辊轮56)滚动连接；形成为大致圆环状的上侧可动导轨57，其用于从上侧固定上述门面50a；上侧固定导轨58，用于从上侧和/或外侧支撑上侧可动导轨57，上侧固定导轨58上设有供上侧可动导轨57滑动的上侧凹槽(图中未示出)，上侧可动导轨57可滑动地设置于上侧凹槽内；上侧可动导轨57可相对上侧固定导轨58滑动或通过两者之间设置的多个辊轮(未图示)滚动。
需要说明的是，在图中，由于金属网孔层与内透视层52紧密贴合，在图中并未具体示出金属网孔层的结构。
在该实施例中，由门面50a、下侧可动导轨54及上侧可动导轨57构成的门体滑动部分可在下侧固定导轨55与上侧固定导轨58(门体非滑动部分)所形成的凹槽内滑动，这种凹槽形式的滑动结构既能确保滑动部件相对非滑动部件接触紧密，又能确保滑动部件相对非滑动部件接触适度宽松，因此能够保证门体在滑动过程中较为平稳且能够防止门体滑动磨损过快及滑动摩擦阻力过大。
另外，通过位于门体50上下两侧的可动导轨和固定导轨之间设置滚动件，将可动导轨和固定导轨之间的滑动连接改为通过滚动件滚动连接，进一步降低两个导轨之间的摩擦阻力和磨损，使得门体50的打开和关闭更加顺畅，提高了轨道结构的使用寿命，降低维护成本，还能避免因磨损产生的渣滓阻碍炉门的滑动。
在上述任一实施例中，优选地，如图5至图12所示，还包括门体驱动电机59，导风罩40形成有固定架402，门体驱动电机59设于固定架402上。
在该实施例中，门体驱动电机59上端设置门体驱动齿轮60，门体驱动齿轮60可与下侧可动导轨54的环状内侧面上形成的齿啮合，这样一来， 门体50可在门体驱动电机59的驱动下自动旋转。
进一步地，如图5至图12所示，导风罩40上开设有用于冷却门体驱动电机59的第一散热孔407，第一散热孔407和第二散热孔410构成冷却风道的至少一部分。
在该实施例中，通过第一散热孔407与第二散热孔410共同构成冷却风道，用于快速冷却门体驱动电机59和微动开关409；另外，固定架402可将门体驱动电机59固定于导风罩40上，使门体驱动电机59与导风罩40的连接更为稳固。
在上述实施例中，优选地，如图6至图12所示，还包括微波发生器403，导风罩40上形成有用于安装微波发生器403的第一安装位404，第一散热孔407、第二散热孔410和第一安装位404构成冷却风道的至少一部分。
在该实施例中，对于具有微波功能的加热烹调器，如微波炉等，微波发生器403可产生微波能，利用微波能对食物进行加热，加热速度快、效率高；第一散热孔407、第二散热孔410和第一安装位404构成冷却电器件的冷却风道的一部分，以使微波发生器403本身产生的热量可以沿冷却风道排出或底部风扇吹出的风沿冷却风道吹向微波发生器403，实现微波发生器403的快速冷却。
需要说明的是，微波发生器403可为磁控管或半导体微波源，当然微波发生器403并不局限于磁控管或半导体微波源，也适用于其他可产生微波能的部件，在此不再一一列举，由于这些技术方案均能够实现本发明的目的，且均没有脱离本发明的设计思想和宗旨，因而均应在本发明的保护范围内。
在上述实施例中，优选地，如图6至图12所示，还包括供电部405，导风罩40上形成用于安装供电部405的第二安装位406，第一散热孔407、第二散热孔410、第一安装位404和第二安装位406构成冷却风道的至少一部分。
在该实施例中，供电部405为加热烹调器的电器件之一，可将市电电压转换为可驱动微波发生器403等电器件工作的工作电压，相配合的第一 散热孔407、第二散热孔410、第一安装位404和第二安装位406构成冷却电器件的冷却风道的一部分，以使供电部405等部件自身产生的热量可以沿冷却风道排出或底部风扇吹出的风沿冷却风道吹向相应部件，实现各个部件的快速冷却。
需要说明的是，供电部405可为变频器或变压器，当然供电部405并不局限于变频器或变压器，也适用于其他具有电压转换功能的转换器，在此不再一一列举，由于这些技术方案均能够实现本发明的目的，且均没有脱离本发明的设计思想和宗旨，因而均应在本发明的保护范围内。
在上述任一实施例中，优选地，如图9所示，导风罩40和腔体20中至少一个部件上设有第一支撑位411，腔体20与导风罩40通过第一支撑位411相连接。
在该实施例中，在导风罩40与腔体20之间设置用于支撑腔体20的第一支撑位411，可以有效减少腔体20内的高温传递至导风罩40，从而避免导风罩40升温过快导致下电器室散热难度增加的问题。
进一步地，第一支撑位411上间隔设有凸筋412。
在该实施例中，第一支撑位411上间隔设置的凸筋412，使导风罩40与腔体20之间形成散热间隙，通过该散热间隙，腔体内因加热烹调器运行而产生的热量进行有效散热，以同时实现腔体20与导风罩40的冷却。
在上述任一实施例中，优选地，如图8和图11所示，还包括至少一组卡接组件，每组卡接组件包括相互配合的卡勾413和卡块414，卡勾413和卡块414中的一个设于底座10上，另一个设于导风罩40上。

在本实施例中，第二支撑位415上间隔设置的散热片416使导风罩40与腔体20之间形成另一散热间隙，通过该散热间隙，腔体20内因加热烹调器运行而产生的热量进行有效散热，以同时实现腔体20与导风罩40的冷却。
进一步地，如图6所示，还包括滤波电源板417，安装在导风罩40上，用于对加热烹调器的电路进行滤波。
