本发明提出一种加热烹调装置100。
本发明的加热烹调装置100可为微波烤箱,当然其也可为烤箱、微波炉等在使用过程中需要对进入腔体内的进风量进行调节的烹调装置,接下来将以微波烤箱为例对本发明的加热烹调装置100进行详细说明。请结合参照图1、图2以及图6和图7,在本发明一实施例中,该加热烹调装置包括壳体10、腔体20及空气驱动装置40,壳体10和腔体20之间形成有风道13,风道13的进风口131与空气驱动装置40的出风口(未标示)连通,壳体10开设有与风道13连通的出风口132,腔体20开设有与风道13连通的腔体进风口211,风道13内并对应腔体进风口211处设有导风组件30,导风组件30控制风道13内的空气进入腔体20的风量大小。
本实施例壳体10包括侧板14、导风罩11以及与导风罩11可拆卸连接的送风罩12,导风罩11一端抵接侧板14,在装配过程中,导风罩11的另一端与送风罩12的端部进行拼接并通过螺钉锁固,以实现风道13的分段式安装,使得风道13的拆装过程较方便。当然导风罩11与送风罩12也可以是通过一体成型方式生产完成。腔体20大致呈长方体状结构,其包括与侧板14相连接的顶板21,以及其他与顶板21和侧板14连接构成密闭空间的板件,导风罩11和送风罩12均罩设在顶板21的上,导风罩11、送风罩12、侧板14以及顶板21围成整个风道13。送风罩12的外端开设有风道13的进风口131,侧板14开设有风道13的出风口132,顶板21开设有连通风道13的腔体进风口211,导风组件30设置在腔体进风口211的上方。本实施例还于腔体进风口211处设有过滤网22(参图3),以对进入腔体20内的空气进行过滤,确保腔体20内的食物品质。空气驱动装置40为涡流风机,其设置在顶板21的上方,并且涡流风机的出风口(未标示)与风道13的进风口131连通。在微波烤箱工作过程中,涡流风机产生的风流一部分通过风道13的出风口132排出,可将安装在腔体20上部的电子元器件产生的热量排出,以确保微波烤箱持续正常工作。另一部分风通过腔体进风口211自上而下进入腔体20,将腔体20内食物加热过程中产生的带有油烟和水蒸气的混合气体由腔体20排出,少部分空气由风道13的出风口132排出。在此过程中,导风组件30对风道13内流经腔体进风口211进入腔体20的风量进行控制,同时也实现对风道13内由出风口132排出空气的风量的控制。
本发明技术方案通过在腔体20的腔体进风口211处设置导风组件30,通过导风组件30实现对风道13流入腔体20的风量进行控制,从而满足微波烤箱在不同工作模式下对进入腔体20的风量也不同的需求,提升了微波烤箱的使用效果。
请结合参照图2至图5,本实施例导风罩11罩设于腔体进风口211上方,导风组件30包括导风板31及电机32,导风板31设于导风罩11内,电机32固定于导风罩11并驱动导风板31于导风罩11内转动。电机32可连接微波烤箱的主控制器(未图示),在微波烤箱工作过程中,在不同的工作模式下,主控制器控制电机32驱动导风板31进行转动以实现对进入腔体20风量的自动控制。
请结合参照图3至图5以及图8和图9,导风罩11结构包括罩体111、及与罩体111连接的两隔板112,两隔板112抵接顶板21并相对设于腔体进风口211的两侧,导风板31位于腔体进风口211的上方并且两端分别枢接于两隔板112,电机32固定于隔板112并且与导风板31的转轴连接。
罩体111和隔板112可通过一体注塑成型方式生产制成。本实施例还于罩体111设置有导流斜面(未标示),并且导流斜面在风道13内空气的流动方向上呈自上而下倾斜,则风道13位于导风罩11的部分从导风罩11连接送风罩12的一端到抵接侧板14的一端逐渐减小,使得涡流风扇送来的风在两隔板112之间汇集,而导风板31架设在两隔板112之间,可实现导风板31在转动过程中,对风道13内的风分流至腔体20内的风量进行有效控制。
本实施例导风板31的结构包括相垂直连接的第一挡板311和第二挡板312,第二挡板312的外端与导风罩11的腔壁之间存在间隙,电机32驱动导风板31在第一位置和第二位置之间转动,导风板31位于第一位置时,第一挡板311遮挡腔体进风口211(参图3),导风板31位于第二位置时,第一挡板311遮挡出风口132(参图6)。
因微波烤箱在工作时,存在着微波加热和烘烤两种模式,本实施例第一位置与微波烤箱的烘烤模式相对应,在烘烤模式下,电机32驱动导风板31旋转而处于第一位置,第一挡板311遮挡腔体进风口211,此时第一挡板311所在平面与腔体进风口211所在平面大致平行,第一挡板311对腔体进风口211实现一定程度的遮盖,使得风道13内的风大部分由第二挡板312与罩体111的腔壁之间的缝隙流过并经出风口132排出,只有较少部分的风能流经第一挡板311与顶板21之间的缝隙并经过腔体进风口211流入腔体20,此时,来自风道13的风不会对烘烤模式下微波烤箱的发热组件(未标示)产生的热风进行干扰,使得微波烤箱在烘烤模式时升温速度快。本实施例第二位置与微波烤箱的微波加热模式相对应,在微波加热模式下,电机32驱动导风板31旋转而处于第二位置,此时第一挡板311遮挡风道13的出风口132,第一挡板311所在平面与出风口132所在平面呈锐角,本实施例优选45°,风道13内的风大部分沿第二挡板312流动并通过腔体进风口211进入腔体20内,将腔体20内食物微波加热过程中产生的带有油烟和水蒸气的混合气体由腔体20排出。微波烤箱在上述的两种工作模式下,由出风口132流出的风都可将腔体20上方的电子元器件产生的热量排出,而降低微波烤箱的部分电子元器件的温度。
请结合参照图4、图5及图9,第二挡板312靠近电机32的一端插接有凸块33,隔板112和罩体111之间形成有限位槽113,凸块33设于限位槽113内。
微波烤箱进行不同工作模式切换时,电机32驱动导风板31旋转过程中,通过凸块33和限位槽113的槽壁的抵接配合,使得导风板31能准确地停止于第一位置和第二位置。
该导风组件30还包括固定于所述罩体111的至少一个微动开关34(参图5和图9),在导风板31转动过程中,凸块33抵接微动开关34。
本实施例微动开关34的数量为一个,导风板31通过凸块33和限位槽113的槽壁的抵接配合作用以及微动开关34对凸块33的检测的双重作用,实现导风板31能更精准的停止于第一位置和第二位置。于其他实施例中,也可在罩体111装设有两个微动开关34,其中一个对应烘烤模式的第一位置,另一个对应微波加热模式的第二位置,当凸块33触碰第一位置的微动开关34时,电机停止工作,导风板31停止于第一位置而进入烘烤模式;当凸块33触碰第二位置的微动开关34时,电机停止工作,导风板31停止于第二位置而进入微波加热模式。
本发明微波烤箱实际工作中,微波烤箱接电后,无论导风板31初始位置在哪个角度,主控制器控制电机32进行自检,如在启动微波加热模式2秒后,因凸块33和限位槽113的配合限位作用,电机32具有转动最大角度限制,当凸块33已经抵接到限位槽113的槽壁而使电机32连续2秒不转动时,主控制器则控制电机32直接进行反转,最后导风板31在转动过程中,带动凸块33触碰到微动开关34的触点后,主控制器再命令电机32正转45°后停止,达到图4位置。在启动烘烤模式2秒后,主控制器控制电机32进行自检(电机32运动到最大角度时,因为有限位结构,当电机32连续2秒不转动时,电机32直接进行反转),当导风板凸点触碰到微动开关34的触点后,主控制器再命令电机32停止工作,达到图1位置。所以,即使出现微波烤箱突然断电的情况,也不会使导风结构工作异常。
以上所述仅为本发明的优选实施例,并非因此限制本发明的专利范围,凡是在本发明的发明构思下,利用本发明说明书及附图内容所作的等效结构变换,或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
