Description

嵌入式微波炉 技术领域
本发明涉及一种微波炉,特别是涉及一种嵌入式微波炉。
背景技术
微波炉本身产生的热量主要来源于磁控管和电源,需要着重对这两个元器件进行散热,否则容易影响微波炉的性能和降低微波炉的使用寿命。微波炉分为台面式微波炉和嵌入式微波炉。其中,嵌入式微波炉的安装方式为嵌入柜子内部,其不会占用台面空间。由于柜子内部不像台面那样四周都与外界连通,其只有柜子前面开口处与外界连通,或者再在柜子内部开一个孔与外界连通,这就对嵌入式微波炉的散热带来了新的挑战。
发明内容
基于此,有必要克服现有技术的缺陷,提供一种嵌入式微波炉,它能够提高散热效果。
其技术方案如下:一种嵌入式微波炉,包括:箱体与门体,所述箱体包括外壳及设置于所述外壳内的烹饪腔体,所述外壳与所述烹饪腔体均设有与所述门体对应的口部,所述门体可打开地盖合于所述口部,所述外壳包括底盖板、第一侧盖板与后盖板,所述第一侧盖板、所述后盖板均和所述底盖板相连,所述底盖板、所述第一侧盖板与所述后盖板中的至少一个板件上设有进风网孔;前板,所述前板绕所述烹饪腔体的口部的周向设置,所述前板的底部设有贯穿所述前板的前侧出风孔,所述外壳的壳壁与所述烹饪腔体的腔壁之间形成间隔区域,所述前侧出风孔和所述间隔区域相连通,当关门时,所述门体与所述前板相贴合封住所述口部;第一隔板,所述第一隔板与所述前板的底边相连或者与所述底盖板的靠近于所述口部的侧边相连,所述第一隔板位于所述门体的下方并与所述门体的底端形成有前侧出风口,所述底盖板的底侧面上设有向下凸伸的支撑脚,所述第一隔板与所述支撑脚所放置的支撑面形成有前侧进风口;及散热风扇,所述散热风扇设置于所述外壳的壳壁与所述烹饪腔体的腔壁之间的间隔区域。

在一个实施例中,请参阅图1至图7。一种嵌入式微波炉,包括箱体10、门体20、前板30、第一隔板40及散热风扇。所述箱体10包括外壳11及设置于所述外壳11内的烹饪腔体12。所述外壳11与所述烹饪腔体12均设有与所述门体20对应的口部,所述门体20可打开地盖合于所述口部,所述外壳11包括底盖板111、第一侧盖板112与后盖板113。所述第一侧盖板112、所述后盖板113均和所述底盖板111相连,所述底盖板111、所述第一侧盖板112与所述后盖板113中的至少一个板件上设有进风网孔。
所述前板30绕所述烹饪腔体12的口部的周向设置,所述前板30的底部设有贯穿所述前板30的前侧出风孔31,所述外壳11的壳壁与所述烹饪腔体12的腔壁之间形成间隔区域,所述前侧出风孔31和所述间隔区域相连通,当关门时,所述门体20与所述前板30相贴合封住所述口部。具体而言,所述第一侧盖板112与所述烹饪腔体12的壳壁之间形成间隔区域和所述前侧出风孔31相连通。
所述第一隔板40与所述前板30的底边相连或者与所述底盖板111的靠近于所述口部的侧边相连。所述第一隔板40位于所述门体20的下方并与所述门体20的底端形成有前侧出风口13,所述底盖板111的底侧面上设有向下凸伸的支撑脚1112,所述第一隔板40与所述支撑脚1112所放置的支撑面210(也就是柜子200的底壁)形成有前侧进风口14。所述散热风扇设置于所述外壳11的壳壁与所述烹饪腔体12的腔壁之间的间隔区域。
上述的嵌入式微波炉工作时,在散热风扇的作用下,外界空气从前侧进风口14进入到进风网孔并进入到外壳11的壳壁与所述烹饪腔体12的腔壁之间的间隔区域,对电子元器件(例如变频电源60和磁控管70)进行风冷后,热风依次从前侧出风孔31、前侧出风口13向外排放。第一隔板40能避免前侧进风口14进入的冷风与前侧出风口13排出的热风相互混流,以及避免前侧出风口13排出的热风直接进入到前侧进风口14后进入箱体10内,起到较好地缓冲作用,即热风从前侧出风口13排出后先与外界空气之间进行散热后,再通过前侧进风口14后进入箱体10内;此外,前侧出风口13排出的热风可以通过第一隔板40往箱体10前方上侧反射,从而不容易被前侧进风口14吸入。
进一步地,请参阅图4至图7,所述门体20面向所述前板30的板面的底部部位上设有底边凹口21,所述底边凹口21与所述前侧出风孔31相对设置。如此,前侧出风孔31向外排出的热风可以在底边凹口21处进行缓冲,进而排出到箱体10外界空气中,即可以增加最终端的出风口面积,提高出风速度。具体地,为了实现底边凹口21更好的缓冲导流效果,底边凹口21的口壁为相对于前侧出风孔31的出风方向倾斜设置的斜壁211。
具体而言,前侧出风孔31可以是多个,并位于前板30的底部部位。
进一步地,请参阅图4至图7,所述门体20面向所述前板30的板面的两个侧部部位上均设有侧边凹口22,两个所述侧边凹口22分别与所述底边凹口21的两端相连通。如此,前侧出风孔31向外排出的热风可以在底边凹口21处进行缓冲,进一步还能在侧边凹口22处进行缓冲,进而排出到箱体10外界空气中,即可以增加最终端的出风口面积,提高出风速度。此外,侧边凹口22的底壁与前板30之间设有间隔不仅是用于形成热风的缓冲通道,还可以作为嵌入式微波炉的开门操作的把手部。
进一步地,请参阅图4至图7,所述外壳11还包括设置于所述烹饪腔体12的顶部的顶盖板114,所述顶盖板114分别与所述第一侧盖板112、所述后盖板113相连。所述烹饪腔体12的顶壁上设有热风组件80,所述顶盖板114罩住所述热风组件80,所述散热风扇排出的 至少一部分风流经所述热风组件80。如此,散热风扇吸取的箱体10外界的冷风流经部分电子元器件(变频电源60与磁控管70)后,再流经烹饪腔体12的顶部的热风组件80,接着流入到烹饪腔体12的侧壁与第一侧盖板112之间的间隔区域,最后经前板30的前侧出风孔31、前侧出风口13排出到箱体10的外界环境中。如此,进入到箱体10内的冷风不仅对变频电源60与磁控管70进行散热,同时还对热风电机83进行散热,能防止热量堆积在箱体10顶部而影响到位于热风组件80边上的控制盒91。具体而言,控制盒91设置于顶盖板114上靠近于门体20的一侧,以便于操作控制盒91。当然,控制盒91也可以设置于顶盖板114上的其它位置。
需要说明的是,请参阅图7与图8,热风组件80包括发热管81,带金属风扇叶的热搅拌风扇82,驱动热搅拌风扇82的热风电机83。
进一步地,请参阅图10至图12,所述的嵌入式微波炉还包括变频电源60与磁控管70。所述烹饪腔体12的顶壁远离于所述门体20的一侧设有横向围边92,所述横向围边92与所述顶盖板114相贴合,所述散热风扇、所述变频电源60与所述磁控管70均设置于所述烹饪腔体12的后壁与所述后盖板113之间的间隔区域。如此,横向围边92实现热风组件80与变频电源60、磁控管70相隔离开,可以防止热风组件80产生的热量蹿到横向围边92后方的变频电源60与磁控管70上,而影响到变频电源60与磁控管70的正常工作。
进一步地,请参阅图11与图12,所述散热风扇包括给所述变频电源60散热的第一风扇51和给所述磁控管70散热的第二风扇52。所述横向围边92包括主体围边921及与所述主体围边921的一端相连的弧形围边922。所述弧形围边922用于将风导向到所述烹饪腔体12的侧壁与所述第一侧盖板112之间的间隔区域。所述烹饪腔体12的顶壁上还设有导向边93,所述导向边93与所述主体围边921的另一端之间设有通风间隔94,所述导向边93朝向所述烹饪腔体12的中部部位延伸设置。如此,第一风扇51吹出的风对变频电源60进行散热,第二风扇52吹出的风对磁控管70进行散热,具有较好的散热效果。此外,散热风扇排出的风的其中一部分风沿着横向围边92流动并进入到烹饪腔体12的侧壁与第一侧盖板112之间的间隔区域,然后再从前板30的前侧出风孔31、前侧出风口13向外排出;散热风扇排出的风的另一部分风则从通风间隔94进入到烹饪腔体12的顶部,接着流经热风组件80并进入到烹饪腔体12的侧壁与第一侧盖板112之间的间隔区域,同样再依次从前板30的前侧出风孔31、前侧出风口13向外排出。
进一步地,请参阅图9至图12,所述进风网孔包括侧进风网孔1121与底进风网孔1111。所述第一侧盖板112靠近于所述后盖板113、所述底盖板111的其中一个角部部位设有所述侧进风网孔1121,所述底盖板111靠近于所述第一侧盖板112、所述后盖板113的其中一个角部部位设有所述底进风网孔1111。所述第一风扇51的进风口的所在面相对于所述底盖板111倾斜设置,所述第一风扇51的进风口的所在面对着所述侧进风网孔1121与所述底进风网孔1111,所述第一风扇51的出风口的所在面对着所述变频电源60设置,所述第二风扇52的进风口的所在面对着所述底进风网孔1111或所述侧进风网孔1121,所述第二风扇52的出风口的所在面对着所述磁控管70设置。如此,一方面,第一风扇51将箱体10外界的空气通过侧进风网孔1121、底进风网孔1111抽入,并吹向变频电源60上给变频电源60进行散热,进入的风量较大对变频电源60有良好的散热效果,第二风扇52则将箱体10外界的空气通过底进风网孔1111或侧进风网孔1121抽入,并吹向磁控管70进行散热,实现磁控管70良好的散热效果;另一方面,由于第一风扇51以其进风口的所在面相对于所述底盖板111倾斜设 置,从而相对于水平设置的方式,能一定程度地减小第一风扇51占用水平向的空间,如此能提高烹饪腔体12的容积的同时能降低散热效果。
具体而言,为了避免进入到烹饪腔体12的侧壁与第一侧盖板112之间的间隔区域的热风被吸入到散热风扇中,在烹饪腔体12的侧壁与第一侧盖板112之间的间隔区域中并靠近于烹饪腔体12的后壁的部位设置有阻隔件95。
进一步地,请参阅图9至图12,所述后盖板113靠近于所述第一侧盖板112、所述底盖板111的其中一个角部部位设有第一后进风网孔1131。如此,在第一风扇51、第二风扇52工作时,箱体10的外界空气还可以通过第一后进风网孔1131进入到箱体10内,以提高进风风量,保证较好的散热效果。
进一步地,请参阅图9至图12,所述第一风扇51设置于所述第二风扇52的上方,所述第一风扇51的中心轴511与所述第二风扇52的中心轴521的夹角为A,A小于90°。需要解释的是,第一风扇51的中心轴511指的是垂直于第一风扇51的进风口的所在面的轴心线,第二风扇52的中心轴521指的是垂直于第二风扇52的进风口的所在面的轴心线。具体而言,第一风扇51的中心轴511与第二风扇52的中心轴521之间的夹角A为30°~40°,较好地,A为36°。
进一步地,所述第二风扇52为涡流风扇,所述涡流风扇的上表面与下表面均设有进风口,所述涡流风扇的下表面连接有第一导风罩96,所述第一导风罩96的顶板设有与所述涡流风扇的下表面的进风口相连通的第一通风口,所述涡流风扇的电机设置于所述第一导风罩96中,所述第一导风罩96罩设于所述底进风网孔1111的一部分区域,所述第一风扇51沿着竖向方向在所述底盖板111上的投影位于所述底进风网孔1111的另一部分区域。如此,第一导风罩96能实现将从底进风网孔1111进入到外壳11内的空气划分为独立隔离的两股风,其中一股风由第一风扇51的进风口吸入,另一股风由第二风扇52的进风口吸入,两股风流不会混乱而部分抵消,提高冷风利用率,保证散热效果;此外,涡流风扇的风扇电机522设置于的第一导风罩96内,进入到第一导风罩96内的风流对风扇电机522起到散热作用,提高风扇电机522的使用寿命。
具体而言,请参阅图9至图12,第一导风罩96包括间隔设置的两个挡板961以及连接两个所述挡板961的安装板962。第一通风口开设形成于安装板962上。挡板961分别与烹饪腔体12的后壁、后盖板113相连。第二风扇52的电机设置于两个挡板961之间。两个挡板961之间的区域与后盖板113的第一后进风网孔1131相对,外界空气可以经第一后进风网孔1131进入到两个挡板961之间。此外,安装板962与底盖板111的底进风网孔1111相对,外界空气也可以经底进风网孔1111进入到第一导风罩96内。
进一步地,请参阅图9至图12,所述第一风扇51与所述第二风扇52之间设有通风间隙53。如此,一部分风经底进风网孔1111进入到第一导风罩96进入到第二风扇52下表面的进风口,另一部分经底进风网孔1111、侧进风网孔1121进入到外壳11内,并从第一风扇51与第二风扇52之间的通风间隙53进入到第二风扇52的上表面的进风口,从而提高了第二风扇52的冷风进风量,具有更好的散热效果。
进一步地,请参阅图9至图12,所述变频电源60的外壳61设有第一横向通风流道,所述第一风扇51的出风口与所述第一横向通风流道的其中一个端口相连通,所述第一横向通风流道的另一个端口的外壁连接有竖向隔板97与横向隔板98。所述竖向隔板97与所述横向隔板98设置于所述磁控管70的***,所述竖向隔板97上设有第二通风口971,所述第二风扇 52的出风口与所述第二通风口971相连通。如此,一方面,第一风扇51的出风口送出的冷风进入到第一横向通风流道中实现对变频电源60较好地散热;另一方面,在竖向隔板97与横向隔板98的作用下,两股风流不会混乱而部分抵消,提高冷风利用率,保证散热效果。
进一步地,横向隔板98还分别与烹饪腔体12的后壁、后盖板113相连。同样地,竖向隔板97还分别与烹饪腔体12的后壁、后盖板113相连。
进一步地,请参阅图9至图12,所述磁控管70的电源连接接头71与所述横向隔板98相邻设置。所述横向隔板98上设有与所述磁控管70的电源连接头相对应的第三通风口981,所述第三通风口981位于所述横向隔板98上靠近于所述竖向隔板97的一侧。如此,第一风扇51的冷风通过第一横向通风流道流出后,其中一部分风再通过第三通风口981流入到磁控管70所在的空间区域,并从上至下流入到磁控管70所在的区域时,与磁控管70充分换热接触,能较好地降低磁控管70的温度。此外,能避免磁控管70的所在区域产生回旋风。
进一步地,请参阅图9至图12,所述的嵌入式微波炉还包括第二导风罩99。所述磁控管70的散热器外壳72设有第二横向通风流道,所述烹饪腔体12的后壁设有第二后进风网孔121,所述第二导风罩99罩设于所述第二后进风网孔121,所述第二通风口971、所述第二横向通风流道、所述第二导风罩99的入风口依次连通。如此,第二风扇52的冷风经过第二通风口971、第二横向通风流道进入到第二导风罩99内,再经第二后进风网孔121进入到烹饪腔体12的内部。
进一步地,请参阅图9至图12,所述第二导风罩99的入风口处设有导热边991,所述导热边991与所述磁控管70相贴合。具体而言,导热边991与磁控管70的散热器外壳72相贴合,利用导热原理将磁控管70的散热器外壳72上的热量传导到第二导风罩99上,提高磁控管70的散热效果。
在一个具体的实施例中,请参阅图9至图12,所述磁控管70的电源连接接头71与所述横向隔板98相邻设置,所述横向隔板98上设有与所述磁控管70的电源连接头相对应的第三通风口981,所述第三通风口981位于所述横向隔板98上靠近于所述竖向隔板97的一侧。所述的嵌入式微波炉还包括第二导风罩99,所述磁控管70的散热器外壳72设有第二横向通风流道,所述烹饪腔体12的后壁设有第二后进风网孔121,所述第二导风罩99罩设于所述第二后进风网孔121,所述第二通风口971、所述第二横向通风流道、所述第二导风罩99的入风口依次连通。如此,当第二导风罩99内仅只是第二风扇52吹出的风时,容易在第二导风罩99内产生回旋风,而在横向隔板98上设置有第三通风口981后,第一风扇51吹出的风可以通过第三通风口981自上而下地进入到磁控管70所在的区域,并进入到第二导风罩99内,从而有利于避免产生回旋风,同时对磁控管70具有较好地散热效果。
进一步地,所述抽屉式微波炉还包括与所述门体20连接的用于放置烹饪物的容器,所述门体20通过滑轨与所述烹饪腔体12的侧壁连接。
进一步地,请参阅图9至图12,所述外壳11还包括第二侧盖板115。所述第二侧盖板115与所述第一侧盖板112相对设置,所述第二侧盖板115分别与所述后盖板113、所述底盖板111相连。所述顶盖板114的三个侧边分别与第一侧盖板112、所述后盖板113及所述第二侧盖板115相连。
以上所述实施例的各技术特征可以进行任意的组合,为使描述简洁,未对上述实施例中的各个技术特征所有可能的组合都进行描述,然而,只要这些技术特征的组合不存在矛盾,都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式,其描述较为具体和详细,但并不能因此而理解为对发明专利范围的限制。应当指出的是,对于本领域的普通技术人员来说,在不脱离本发明构思的前提下,还可以做出若干变形和改进,这些都属于本发明的保护范围。因此,本发明专利的保护范围应以所附权利要求为准。
