Description

密封环及烹饪器具
本申请要求于2017年4月14日提交中国专利局、申请号为201720393011X、发明名称为“密封环及烹饪器具”、于2017年4月14日提交中国专利局、申请号为2017203964328、发明名称为“密封环及烹饪器具”、于2017年4月14日提交中国专利局、申请号为201720402801X、发明名称为“烹饪器具”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本发明涉及厨房用具领域,更具体而言,涉及一种密封环和包括该密封环的烹饪器具。
背景技术
现有的烹饪器具例如电饭煲,其盖体1’通过密封环3’与内锅2’进行密封,密封环3’与内锅2’的配合部分一般呈“V”字型或者“U”字型。这种密封环3’在盖体1’未关闭状态下的结构如图1所示,在盖体1’闭合状态下的结构如图2所示。
在煮饭一定时间或者保温后,由于锅内与锅外温度存在较大的温度差,密封环处由于离保温加热器件距离较远且较薄弱,很容易受到外部相对低温的空气影响而导致密封环外的温度比较低,锅内的水蒸汽遇到温度较低的密封环时,遇冷凝结成水珠。打开盖体时,会有较多的水流到电饭煲的外壳罩和盖体上,对用户形成不好的体验。这种冷凝水不仅让用户困扰,同时还可能保温时会滴到米饭上,导致“滴白”现象,容易使米饭变质。
为解决上述问题,有部分电饭煲设置了接水盒,这种措施虽然避免了水流到电饭煲外壳罩上,但是电饭煲本身还是会产生冷凝水,只是将冷凝水接到接水盒中,不但要增加接水盒的成本,也没有从根本上解决遇冷凝 结成水珠的问题,“滴白”现象也不能解决。
发明内容
本发明旨在至少解决现有技术中存在的技术问题之一。
为此,本发明的一个方面的目的在于提供一种密封环。
本发明的另一个方面的目的在于提供一种包括上述密封环的烹饪器具。
为实现上述目的,本发明的一个方面的实施例提供了一种密封环,用于烹饪器具,所述烹饪器具包括煲体和盖设在所述煲体上的盖体,所述煲体包括内锅,所述密封环包括:依次相连接的连接部、支撑部、压缩部和密封部,其中,所述连接部连接在所述盖体上,沿由外向内的方向,所述支撑部向上倾斜,且沿由外向内的方向,所述压缩部逐渐向下倾斜,所述支撑部与所述压缩部的连接处形成开口朝内的腔体,合盖时,所述密封部向靠近所述腔体的开口端的方向运动,且合盖状态下所述密封部密封所述腔体的开口端,所述压缩部与所述内锅相贴合。
本发明上述实施例提供的密封环,用于烹饪器具的内锅与盖体之间的密封。从上到下密封环包括依次相连接的连接部、支撑部、压缩部和密封部,连接部连接在盖体上,沿由外向内的方向,支撑部向上倾斜,优选地,支撑部逐渐向上倾斜,且沿由外向内的方向,压缩部逐渐向下倾斜,使得支撑部和压缩部的连接处形成开口朝内、截面呈V形或U形或其它形状的腔体,压缩部的下端连接有密封部,合盖时,压缩部与内锅相接触,并与内锅的开口处存在挤压,在压缩部与内锅挤压的过程中,密封部向靠近腔体的开口端运动,并在合盖状态下密封腔体的开口端,使腔体形成与外界隔绝的密封空腔。煮饭或保温时,一方面,密封空腔内的空气不流动,从而密封空腔隔离了内锅内高温高湿的环境,也隔离了外界的低温环境,在密封空腔内形成中高温环境,降低了内锅外侧的低温环境与内锅内的高温环境的热传导,提高了保温效果,内锅里面的高温高湿环境与密封空腔内的温差也比现有技术中腔体未闭合情况下减少了,从而减少了冷凝水珠的形成量和形成的冷凝水的水滴尺寸,另一方面,形成密封空腔后也减少了密封环与内锅里面的高温高湿环境的接触面积,进一步 减少了冷凝水的形成量,从而达到解决冷凝水流到外壳罩和盖板上的问题。
在盖体闭合状态下,压缩部贴合在内锅的开口处,相关技术中,压缩部的下端连接水平设置的水平部,水平部上再连接密封部,盖体闭合后,水平部与内锅的开口处相贴合,密封部密封压缩部与支撑部形成的腔体。本申请中加大了由开盖状态到合盖状态下密封环的压缩量,使得压缩部与内锅的开口处相贴合,从而使得压缩部可以直接与密封部相连接,无需设置水平部,简化了密封环的结构,降低了密封环的成本。
煲体与盖体相铰接,或旋合扣接,或盖体放置在煲体上并与煲体相连接。
另外,本发明上述实施例提供的密封环还具有如下附加技术特征:
上述技术方案中,优选地,由开盖状态到合盖状态,所述密封环的压缩量为2mm~10mm。
盖体闭合时,密封环与内锅相接触并与内锅之间存在挤压作用,在内锅的作用下,密封环被压缩,使得密封部向靠近腔体的开口端的方向运动,并密封腔体的开口端。由开盖状态到合盖状态,密封环的压缩量为2mm~10mm,既能保证合盖状态下密封环形成密封空腔后有一定的过盈量,又不至于因密封环的压缩量过大导致合盖力太大。优选地,密封环的压缩量为3mm~5mm。密封环的压缩量可以为2mm、3mm、4mm、5mm、6mm、7mm、8mm、9mm、10mm。
上述技术方案中,优选地,合盖状态下所述密封部至少部分与所述内锅相贴合。
合盖状态下,除压缩部与内锅相贴合外,密封部上至少部分与内锅相贴合,进一步减少了密封环上与内锅侧的高温高湿环境的接触面积,从而进一步减少冷凝水的形成量。优选地,密封部上靠近压缩部的部分与内锅相贴合。
上述技术方案中,优选地,所述连接部或所述连接部与所述支撑部的连接处向靠近所述盖体轴线的方向延伸形成延伸部,所述延伸部贴合在所述盖体的下表面上;合盖状态下所述密封部与所述延伸部相抵接。
连接部的下端的内表面或连接部与支撑部的连接处的内表面向内延伸,形成延伸部,延伸部能够进一步提高对盖体的密封效果,优选地,沿由外向内的方向,延伸部向下倾斜。合盖状态下,密封部抵接在延伸部上形成密封空腔。
上述技术方案中,优选地,所述密封部与所述延伸部的抵接处和所述延伸 部的自由端之间的距离为0mm~3mm。
合盖状态下,密封部与延伸部的抵接处与延伸部自由端之间的距离越小越好,可减少延伸部与内锅内的高温高湿环境的接触面积,进一步减少冷凝水形成。理想状态下密封部与延伸部的抵接处与延伸部的自由端之间的距离为0mm。实际应用过程中密封部与延伸部的抵接处与延伸部的自由端之间的距离可以为0mm、1mm、2mm、3mm。
上述技术方案中,优选地,合盖状态下所述密封部与所述支撑部相抵接;或者,合盖状态下所述密封部与所述连接部和所述支撑部的连接处相抵接;或者,合盖状态下所述密封部与所述盖体相抵接。
合盖状态下,密封部抵接在支撑部上形成密封空腔,或者,密封部抵接在连接部与支撑部的连接处形成密封空腔,或者,密封部抵接在盖体的下表面上形成密封空腔。优选地,密封环连接在活动盖板上,密封部抵接在活动盖板的下表面上形成密封空腔。
上述技术方案中,优选地,所述支撑部的厚度大于所述压缩部的厚度。
支撑部的厚度大于压缩部的厚度,使得合盖时,压缩部先于支撑部发生变形,从而使得合盖状态下压缩部与内锅的开口处相贴合,且压缩部形变过程中,带动密封部向上翘,从而密封腔体的开口端。
上述技术方案中,优选地,所述支撑部的厚度与所述压缩部的厚度的差值为0.1mm~0.3mm。
支撑部的厚度减去压缩部的厚度的差值不小于0.1mm,保证压缩部先于支撑部发生形变,同时支撑部的厚度减去压缩部的厚度的差值不大于0.3mm,避免支撑部厚度过大或压缩部厚度过小。
上述技术方案中,优选地,开盖状态下所述支撑部与水平面的夹角大于所述压缩部与水平面的夹角,使得合盖时,压缩部先于支撑部发生变形,从而使得合盖状态下压缩部与内锅的开口处相贴合,且压缩部形变过程中,带动密封部向上翘,从而密封腔体的开口端。此处开盖状态指的是密封环未受压缩,且烹饪器具的盖体水平放置的状态。
上述技术方案中,优选地,开盖状态下所述支撑部与水平面的夹角为42°~60°;和/或,开盖状态下所述压缩部与水平面的夹角为30°~48°;和/或, 开盖状态下所述支撑部与水平面的夹角和所述压缩部与水平面的夹角的差值大于或等于5°。
优选地,开盖状态下支撑部与水平面的夹角为42°、45°、50°、55°、60°;开盖状态下压缩部与水平面的夹角为30°、35°、40°、45°、48°。
上述技术方案中,优选地,所述密封部水平设置;或者,所述密封部向靠近所述腔体的开口端的方向倾斜。
开盖状态下密封部水平设置,在合盖时,压缩部被压缩并带动密封部向靠近腔体的开口端的方向运动,从而密封腔体;或者,开盖状态下,沿由外向内的方向,密封部逐渐向上倾斜,能够减小由开盖状态到合盖状态密封环的压缩量。
上述技术方案中,优选地,所述密封环还包括:贴合部,位于所述连接部与所述支撑部之间,所述贴合部贴合在所述盖体的下表面上。
密封环还包括贴合部,贴合部的一端连接在连接部上,贴合部的另一端连接在支撑部上。贴合部贴合在盖体的下表面上,合盖时,使得压缩部易于被压缩。优选地,连接部延伸形成延伸部或连接部与贴合部的连接处延伸形成延伸部。优选地,贴合部水平设置。
上述技术方案中,优选地,所述密封环上设有筋条,合盖状态下,所述筋条抵接在所述密封空腔的内壁面上或所述筋条位于所述密封部与所述腔体的抵接处,且所述筋条被压缩。
在合盖时,密封部与腔体相抵接从而密封腔体的开口端,使腔体形成与外界隔绝的密封空腔。开盖时密封空腔负压的作用力可能会大于密封环张开力,使得密封空腔无法打开、无法回复原来形状,导致开盖时密封环无法兜住盖体上的冷凝水。为防止密封空腔无法打开的现象发生,在密封环上设有筋条,且由开盖状态到合盖状态形成密封空腔的过程中,筋条受压缩,并在合盖状态下,筋条抵接在密封空腔的内壁面上或筋条位于密封部与腔体的抵接处,从而在开盖时,除密封环张开力外还存在筋条的作用力,由于筋条的作用力加上密封环的张开力大于负压作用力,从而达到开盖后使密封环回复到常态的目的。可以在密封环上设置一个或多个筋条,优选地,设置多个筋条时,多个筋条在密封环上均匀分布。
至于筋条的位置,筋条的一端连接在密封部上或腔体的壁面上或连接在连接部与支撑部的连接处,合盖状态下筋条的另一端抵接在密封空腔的内壁面上,且筋条受压缩,这样开盖时筋条回弹提供有助于密封空腔打开的作用力,或者合盖状态下筋条位于密封部与腔体的抵接处,该抵接处是指合盖状态下密封部与腔体相抵接从而对腔体形成密封的密封处,即筋条位于密封部与腔体上合盖状态下与密封部的抵接处之间,且筋条上位于密封部与腔体的抵接处的部分被压缩,使得开盖时筋条回弹也能够提供由于密封腔体打开的作用力。当然还可以设置在其它位置,只需形成密封空腔时筋条受压缩,开盖时,筋条能够提供有助于密封空腔打开的力即可。
上述技术方案中,优选地,在合盖状态下所述密封部与所述盖体相抵接的情况下,所述筋条位于所述密封部上;或者,在合盖状态下所述密封部与所述支撑部相抵接的情况下,所述筋条包括设置在所述密封部上的第一筋条和/或设置在所述支撑部上与所述密封部相抵接处的第二筋条;或者,在合盖状态下所述密封部与所述连接部和所述支撑部的连接处相抵接的情况下,所述筋条包括设置在所述密封部上的第一筋条和/或设置在所述支撑部与所述连接部的连接处的第二筋条;或者,在所述连接部或所述连接部与所述支撑部的连接处向靠近所述盖体轴线的方向延伸形成延伸部,所述延伸部贴合在所述盖体的下表面上;合盖状态下所述密封部与所述延伸部相抵接的情况下,所述筋条包括设置在所述密封部上的第一筋条和/或设置在所述延伸部上的第二筋条。
密封部连接在压缩部的下端,合盖状态下,密封部抵接在盖体上,筋条位于密封部上。合盖状态下密封部抵接在盖体上形成密封空腔。合盖时,密封部向靠近盖体的方向运动并抵接在盖体上,将筋条设置在密封部上,优选地,设置在密封部的上表面上,使得合盖过程中筋条受到压缩,在开盖时,筋条释放弹性势能,筋条的作用力与密封环张开力的和力使得密封空腔打开。当然,筋条还可以位于支撑部和/或压缩部上,只需要合理设置筋条的位置和尺寸使得形成密封空腔时筋条受压缩,开盖时筋条提供有助于密封空腔打开的作用力。
或者,密封部连接在压缩部的下端,合盖状态下,密封部抵接在支撑部上,筋条包括设置在密封部上的第一筋条和/或设置在支撑部上与密封部相抵接处的第二筋条。合盖状态下密封部抵接在支撑部上形成密封空腔。为保证合盖状 态下,筋条易于受到压缩,筋条包括设置在密封部上的第一筋条和/或设置在支撑部上的第二筋条,且第二筋条位于支撑部上与密封部相抵接处。优选地,第一筋条设置在密封部的上表面上,第二筋条设置在支撑部的下表面上。当然,筋条还可以设置在其它位置,只需要形成密封空腔时筋条受压缩,开盖时筋条提供有助于密封空腔打开的作用力。
或者,密封部连接在压缩部的下端,合盖状态下,密封部抵接在支撑部与连接部的连接处,筋条包括设置在密封部上的第一筋条和/或设置在支撑部与连接部的连接处的第二筋条。合盖状态下密封部抵接在支撑部与连接部的连接处形成密封空腔。为保证合盖状态下,筋条易于受到压缩,筋条包括设置在密封部上的第一筋条和/或设置在支撑部与连接部的连接处的第二筋条,且第二筋条位于支撑部与连接部的连接处上与密封部相抵接处。优选地,第一筋条设置在密封部的上表面上,第二筋条设置在支撑部与连接部的连接处的下表面上。当然,筋条还可以设置在其它位置,只需要形成密封空腔时筋条受压缩,开盖时筋条提供有助于密封空腔打开的作用力。
或者,密封部连接在压缩部的下端。连接部的下端的内表面或连接部与支撑部的连接处的内表面向靠近盖体轴线的方向延伸,形成延伸部,延伸部能够进一步提高对盖体的密封,优选地,沿由外向内的方向,延伸部向下倾斜。合盖状态下,密封部抵接在延伸部上形成密封空腔。为保证合盖状态下,筋条易于受到压缩,筋条包括设置在密封部上的第一筋条和/或设置在延伸部上的第二筋条,且第二筋条位于延伸部上与密封部相抵接处。优选地,第一筋条设置在密封部的上表面上,第二筋条设置在延伸部的下表面上。当然,筋条还可以设置在其它位置,只需要形成密封空腔时筋条受压缩,开盖时筋条提供有助于密封空腔打开的作用力。
当然,密封部也可以连接在支撑部上或支撑部与连接部的连接处,合盖状态下,密封部抵接在压缩部上,筋条包括设置在密封部上的第一筋条和/或设置在压缩部与密封部抵接处上的第二筋条;或者,密封部连接在支撑部上或支撑部与连接部的连接处,合盖状态下,密封部抵接在内锅上,筋条设置在密封部上。
当然,除合盖状态下压缩部贴合在内锅上外,还可以在压缩部与密封部之 间连接有变形段,合盖状态下变形段抵接在内锅上,当变形段抵接在内锅上时,压缩部可以抵接在内锅上,也可以不抵接在内锅上。相比于合盖状态下压缩部抵接在内锅上,变形段与内锅相贴合能够减小由开盖状态到合盖状态密封环的压缩量。优选地,变形段水平设置。
本发明第二个方面的实施例提供一种烹饪器具,所述烹饪器具包括:煲体,所述煲体包括内锅;盖体,盖设在所述煲体上;和上述任一实施例所述的密封环,所述密封环的连接部连接在所述盖体上。
本发明第二个方面的实施例提供的烹饪器具,因包括第一个方面的实施例所述的密封环,因而具有第一个方面的密封环的所有有益效果。
上述技术方案中,优选地,所述密封部远离所述连接部的一端向上凸出形成凸起,所述凸起用于加强所述密封部的强度;其中,合盖状态下所述密封部贴合在所述内锅的上表面上,且不凸出所述内锅的内壁面,所述凸起闭合所述腔体,以使所述腔体形成密封空腔。
合盖状态下,密封部贴合在内锅的上表面上,实现内锅与盖体之间的密封。密封部上远离连接部的一端(密封部的末端)设有凸起,以加强密封部的强度,避免合盖过程中密封部外翻导致密封部与内锅的上表面不能良好的贴合,此处可以理解为密封部包括密封本体和密封本体的末端凸出形成的凸起,凸起用于加强密封本体的强度。在合盖时,凸起密封腔体的开口端,使腔体形成与外界隔绝的密封空腔。在合盖时,凸起密封腔体的开口端,使腔体形成与外界隔绝的密封空腔。煮饭或保温时,密封空腔把内锅内高温高湿的环境隔离了,也隔离了外界的低温环境,密封空腔内部湿度低,难以形成冷凝水,且合盖状态下,由于除压缩部贴合在内锅的上表面上外,密封部也贴合在内锅的上表面上,且密封部与内锅的内壁面相平齐或位于内锅的内壁面的外侧,即密封部不凸出内锅的内壁面,使得密封部不会与内锅内的高温高湿环境接触,使得密封部上不会形成冷凝水,使得密封环上只有凸起与内锅里面的高温高湿环境接触,接触面积很小,即使还存在一定温差,形成的冷凝水珠尺寸也较小,量也少,从而达到解决冷凝水流到外壳罩和活动盖板上的问题。
相比于相关技术中,需要在密封部的末端单独设置密封部位,合盖状 态下密封部位闭合腔体相比,本申请中利用密封环上用于加强密封部(密封本体)强度的凸起实现腔体的密封,无需设置单独的密封部位,降低了密封环的成本。
上述技术方案中,优选地,0.5T≤H≤2T,H为所述凸起的高度,T为所述密封部的厚度。
0.5T≤H≤2T既能保证凸起对密封部(密封本体)良好的加强作用,又避免凸起过高使得凸起尺寸过大从而与内锅内的高温高湿环境的接触面积过大,导致冷凝水的形成量增大。
优选地,H=0.5T、或H=T、或H=1.5T、或H=2T。

合盖状态下,密封部水平设置,内锅的上表面上与密封部相贴合处可以是水平面,也可以是由内向外向上或向下倾斜的倾斜面,但合盖状态下通过调整密封环的压缩量等以保证密封部的至少部分贴合在内锅的上表面上。或者,合盖状态下沿由外向内的方向密封部向上倾斜,形成第一倾斜面,为保证内锅的上表面与第一倾斜面的良好贴合,内锅的上表面上与第一倾斜面相对应处形成第二倾斜面,优选地,第二倾斜面的倾斜角度与第一倾斜面的倾斜角度一致。当合盖状态下沿由外向内的方向密封部向上倾斜形成第一倾斜面时,在开盖状态,密封环上可以只有密封部可以沿水平方向设置,也可以沿由外向内的方向密封部向上倾斜。当然,此时密封部与锅沿相贴合或密封部和压缩部均与锅沿相贴合。

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方式来实施,因此,本发明的保护范围并不受下面公开的具体实施例的限制。
下面参照附图3至14描述根据本发明一些实施例的密封环3和烹饪器具。
如图3至图6所示,根据本发明一些实施例提供的一种密封环3,用于烹饪器具,烹饪器具包括煲体和盖设在煲体上的盖体1,煲体包括内锅2,密封环3包括依次相连接的连接部31、支撑部32、压缩部33和密封部34,其中,连接部31连接在盖体1上,沿由外向内的方向,支撑部32向上倾斜,且 沿由外向内的方向,压缩部33逐渐向下倾斜,支撑部32与压缩部33的连接处形成开口朝内的腔体4,合盖时,密封部34向靠近腔体4的开口端的方向运动,且合盖状态下密封部34密封腔体4的开口端,压缩部33与内锅2相贴合。
本发明上述实施例提供的密封环3,用于烹饪器具的内锅2与盖体1之间的密封。从上到下密封环3包括依次相连接的连接部31、支撑部32、压缩部33和密封部34,连接部31连接在盖体1上,沿由外向内的方向,支撑部32向上倾斜,优选地,支撑部32逐渐向上倾斜,且沿由外向内的方向,压缩部33逐渐向下倾斜,使得支撑部32和压缩部33的连接处形成开口朝内、截面呈V形或U形或其它形状的腔体4,压缩部33的下端连接有密封部34,合盖时,压缩部33与内锅2相接触,并与内锅2的开口处存在挤压,在压缩部33与内锅2挤压的过程中,密封部34向靠近腔体4的开口端运动,并在合盖状态下密封腔体4的开口端,使腔体4形成与外界隔绝的密封空腔5。煮饭或保温时,一方面,密封空腔5内的空气不流动,从而密封空腔5隔离了内锅2内高温高湿的环境,也隔离了外界的低温环境,在密封空腔5内形成中高温环境,降低了内锅2外侧的低温环境与内锅2内的高温环境的热传导,提高了保温效果,内锅2里面的高温高湿环境与密封空腔5内的温差也比现有技术中腔体4未闭合情况下减少了,从而减少了冷凝水珠的形成量和形成的冷凝水的水滴尺寸,另一方面,形成密封空腔5后也减少了密封环3与内锅2里面的高温高湿环境的接触面积,进一步减少了冷凝水的形成量,从而达到解决冷凝水流到外壳罩和盖板上的问题。
在盖体1闭合状态下,压缩部33贴合在内锅2的开口处,相关技术中,压缩部33的下端连接水平设置的水平部,水平部上再连接密封部34,盖体1闭合后,水平部与内锅2的开口处相贴合,密封部34密封压缩部33与支撑部32形成的腔体4。本申请中加大了由开盖状态到合盖状态下密封环3的压缩量,使得压缩部33与内锅2的开口处相贴合,从而使得压缩部33可以直接与密封部34相连接,无需设置水平部,简化了密封环3的结构,降低了密封环3的成本。
实施例一:
如图3和图4所示,密封环3包括依次相连接的连接部31、支撑部32、压缩部33和密封部34,其中,连接部31连接在盖体1上,沿由外向内的方向,支撑部32向上倾斜,且沿由外向内的方向,压缩部33逐渐向下倾斜,支撑部32与压缩部33的连接处形成开口朝内的腔体4,合盖时,密封部34向靠近腔体4的开口端的方向运动,且合盖状态下密封部34密封腔体4的开口端,压缩部33与内锅2相贴合。
优选地,如图3和图4所示,由开盖状态到合盖状态,密封环3的压缩量(b-a)为2mm~10mm。
盖体1闭合时,密封环3与内锅2相接触并与内锅2之间存在挤压作用,在内锅2的作用下,密封环3被压缩,使得密封部34向靠近腔体4的开口端的方向运动,并密封腔体4的开口端。由开盖状态到合盖状态,密封环3的压缩量为2mm~10mm,既能保证合盖状态下密封环3形成密封空腔5后有一定的过盈量,又不至于因密封环3的压缩量过大导致合盖力太大。优选地,密封环3的压缩量为3mm~5mm。密封环3的压缩量可以为2mm、3mm、4mm、5mm、6mm、7mm、8mm、9mm、10mm。
优选地,合盖状态下密封部34至少部分与内锅2相贴合。
合盖状态下,除压缩部33与内锅2相贴合外,密封部34上至少部分与内锅2相贴合,进一步减少了密封环3上与内锅2侧的高温高湿环境的接触面积,从而进一步减少冷凝水的形成量。优选地,密封部34上靠近压缩部33的部分与内锅2相贴合。
优选地,连接部31或连接部31与支撑部32的连接处向靠近盖体1轴线的方向延伸形成延伸部35,延伸部35贴合在盖体1的下表面上;合盖状态下密封部34与延伸部35相抵接。
连接部31的下端的内表面或连接部31与支撑部32的连接处的内表面向内延伸,形成延伸部35,延伸部35能够进一步提高对盖体1的密封效果,优选地,沿由外向内的方向,延伸部35向下倾斜。合盖状态下,密封部34抵接在延伸部35上形成密封空腔5。
优选地,如图4所示,密封部34与延伸部35的抵接处和延伸部35的自由端之间的距离W为0mm~3mm。
合盖状态下,密封部34与延伸部35的抵接处与延伸部35自由端之间的距离越小越好,可减少延伸部35与内锅2内的高温高湿环境的接触面积,进一步减少冷凝水形成。理想状态下密封部34与延伸部35的抵接处与延伸部35的自由端之间的距离为0mm。实际应用过程中密封部34与延伸部35的抵接处与延伸部35的自由端之间的距离可以为0mm、1mm、2mm、3mm。
优选地,如图5所示,支撑部32的厚度c大于压缩部33的厚度d。
支撑部32的厚度大于压缩部33的厚度,使得合盖时,压缩部33先于支撑部32发生变形,从而使得合盖状态下压缩部33与内锅2的开口处相贴合,且压缩部33形变过程中,带动密封部34向上翘,从而密封腔体4的开口端。
优选地,支撑部32的厚度与压缩部33的厚度的差值(c-d)为0.1mm~0.3mm。
支撑部32的厚度减去压缩部33的厚度的差值不小于0.1mm,保证压缩部33先于支撑部32发生形变,同时支撑部32的厚度减去压缩部33的厚度的差值不大于0.3mm,避免支撑部32厚度过大或压缩部33厚度过小。
优选地,如图3所示,开盖状态下支撑部32与水平面的夹角α大于压缩部33与水平面的夹角β,使得合盖时,压缩部33先于支撑部32发生变形,从而使得合盖状态下压缩部33与内锅的开口处相贴合,且压缩部33形变过程中,带动密封部向上翘,从而密封腔体的开口端。此处开盖状态指的是密封环3未受压缩,且烹饪器具的盖体水平放置的状态。
优选地,开盖状态下支撑部32与水平面的夹角α为42°~60°;和/或,开盖状态下压缩部33与水平面的夹角β为30°~48°;和/或,开盖状态下支撑部32与水平面的夹角和压缩部33与水平面的夹角的差值(α-β)大于或等于5°。
优选地,开盖状态下支撑部32与水平面的夹角为42°、45°、50°、55°、60°;开盖状态下压缩部33与水平面的夹角为30°、35°、40°、45°、48°。
优选地,如图3所示,密封部34水平设置。
开盖状态下密封部34水平设置,在合盖时,压缩部33被压缩并带动密封部34向靠近腔体4的开口端的方向运动,从而密封腔体4。
优选地,密封环3还包括:贴合部36,位于连接部31与支撑部32之间,贴合部36贴合在盖体1的下表面上。
密封环3还包括贴合部36,贴合部36的一端连接在连接部31上,贴合部36的另一端连接在支撑部32上。贴合部36贴合在盖体1的下表面上,合盖时,使得压缩部33易于被压缩。优选地,连接部31延伸形成延伸部35或连接部31与贴合部36的连接处延伸形成延伸部35。优选地,贴合部36水平设置。
优选地,如图7至图10所示,密封环3上设有筋条,合盖状态下,筋条抵接在密封空腔5的内壁面上或筋条位于密封部34与腔体4的抵接处,且筋条被压缩。
在合盖时,密封部34与腔体4相抵接从而密封腔体4的开口端,使腔体4形成与外界隔绝的密封空腔5。开盖时密封空腔5负压的作用力可能会大于密封环3张开力,使得密封空腔5无法打开、无法回复原来形状,导致开盖时密封环3无法兜住盖体1上的冷凝水。为防止密封空腔5无法打开的现象发生,在密封环3上设有筋条,且由开盖状态到合盖状态形成密封空腔5的过程中,筋条受压缩,并在合盖状态下,筋条抵接在密封空腔5的内壁面上或筋条位于密封部34与腔体4的抵接处,从而在开盖时,除密封环3张开力外还存在筋条的作用力,由于筋条的作用力加上密封环3的张开力大于负压作用力,从而达到开盖后使密封环3回复到常态的目的。可以在密封环3上设置一个或多个筋条,优选地,设置多个筋条时,多个筋条在密封环3上均匀分布。
至于筋条的位置,筋条的一端连接在密封部34上或腔体4的壁面上或连接在连接部31与支撑部32的连接处,合盖状态下筋条的另一端抵接在密封空腔5的内壁面上,且筋条受压缩,这样开盖时筋条回弹提供有助于密封空腔5打开的作用力,或者合盖状态下筋条位于密封部34与腔体4的抵接处(抵接处如图6中E处所示),该抵接处是指合盖状态下密封部34与腔体4相抵接从而对腔体4形成密封的密封处,即筋条位于密封部34与腔体4上合盖状态下与密封部34的抵接处之间,且筋条上位于密封部34与腔体4的抵接处的部分被压缩,使得开盖时筋条回弹也能够提供由于密封腔体4打开的作用力。当然筋条还可以设置在其它位置,只需形成密封空腔5时筋条受压缩,开盖时,筋条能够提供有助于密封空腔5打开的力即可。
优选地,如图3、图6、图7至图10所示,筋条包括设置在密封部34上 的第一筋条343和/或设置在延伸部35上的第二筋条351。
密封部34连接在压缩部33的下端。连接部31的下端的内表面或连接部31与支撑部32的连接处的内表面向靠近盖体1轴线的方向延伸,形成延伸部35,延伸部35能够进一步提高对盖体1的密封,优选地,沿由外向内的方向,延伸部35向下倾斜。合盖状态下,密封部34抵接在延伸部35上形成密封空腔5。为保证合盖状态下,筋条易于受到压缩,筋条包括设置在密封部34上的第一筋条343和/或设置在延伸部35上的第二筋条351,且第二筋条351位于延伸部35上与密封部34相抵接处。优选地,第一筋条343设置在密封部34的上表面上,第二筋条351设置在延伸部35的下表面上。当然,筋条还可以设置在其它位置,只需要形成密封空腔5时筋条受压缩,开盖时筋条提供有助于密封空腔5打开的作用力。
至于筋条位于密封空腔5内的情形,例如支撑部32上设有向压缩部33的方向凸出的筋条,合盖状态下筋条抵接在压缩部33上并处于受压缩的状态。
实施例二:
与实施例一的不同在于,如图5和图6所示,密封部34向靠近腔体4的开口端的方向倾斜。
开盖状态下,沿由外向内的方向,密封部34逐渐向上倾斜,能够减小由开盖状态到合盖状态密封环3的压缩量。当密封部34向靠近腔体4的开口端的方向倾斜时,由开盖状态到合盖状态,密封环3的压缩量为m-n。

实施例四:

实施例五:
与实施例一和实施例二的不同在于,合盖状态下密封部34与盖体1相抵接。

优选地,筋条位于密封部34上。
密封部34连接在压缩部33的下端,合盖状态下,密封部34抵接在盖体1上,筋条位于密封部34上。合盖状态下密封部34抵接在盖体1上形成密封空腔5。合盖时,密封部34向靠近盖体1的方向运动并抵接在盖体1上,将 筋条设置在密封部34上,优选地,设置在密封部34的上表面上,使得合盖过程中筋条受到压缩,在开盖时,筋条释放弹性势能,筋条的作用力与密封环3张开力的和力使得密封空腔5打开。当然,筋条还可以位于支撑部32和/或压缩部上,只需要合理设置筋条的位置和尺寸使得形成密封空腔5时筋条受压缩,开盖时筋条提供有助于密封空腔5打开的作用力。
本发明第二个方面的实施例提供一种烹饪器具,烹饪器具包括:煲体,煲体包括内锅2;盖体1,盖设在煲体上;上述任一实施例的密封环3,密封环3的连接部31连接在盖体1上。
本发明第二个方面的实施例提供的烹饪器具,因包括第一个方面的实施例的密封环3,因而具有第一个方面的密封环3的所有有益效果。
优选地,如图11至图13所示,密封部34远离连接部31的一端向上凸出形成凸起342,凸起342用于加强密封部34的强度;其中,合盖状态下密封部34贴合在内锅2的上表面上,且不凸出内锅2的内壁面,凸起342闭合腔体4,以使腔体4形成密封空腔5。
合盖状态下,密封部34贴合在内锅2的上表面上,实现内锅2与盖体1之间的密封。密封部34上远离连接部31的一端(密封部34的末端)设有凸起342,以加强密封部34的强度,避免合盖过程中密封部34外翻导致密封部34与内锅2的上表面不能良好的贴合,此处可以理解为密封部34包括密封本体341和密封本体341的末端凸出形成的凸起342,凸起342用于加强密封本体341的强度。在合盖时,凸起342密封腔体4的开口端,使腔体4形成与外界隔绝的密封空腔。在合盖时,凸起342密封腔体4的开口端,使腔体4形成与外界隔绝的密封空腔5。合盖状态下,由于除压缩部贴合在内锅的上表面上外,密封部34也贴合在内锅2的上表面上,且密封部34与内锅2的内壁面相平齐或位于内锅2的内壁面的外侧,即密封部34不凸出内锅2的内壁面,使得密封部34不会与内锅2内的高温高湿环境接触,使得密封部34上不会形成冷凝水,使得密封环3上只有凸起342与内锅2里面的高温高湿环境接触,接触面积很小,即使还存在一定温差,形成的冷凝水珠尺寸也较小,量也少,从而达到解决冷凝水流到外壳罩和活动盖板上的问题。
优选地,如图3所示,0.5T≤H≤2T,H为凸起342的高度,T为密封部34的厚度。
0.5T≤H≤2T既能保证凸起342对密封部34(密封本体341)良好的加强作用,又避免凸起342过高使得凸起342尺寸过大从而与内锅2内的高温高湿环境的接触面积过大,导致冷凝水的形成量增大。
优选地,H=0.5T、或H=T、或H=1.5T、或H=2T。
优选地,凸起342与密封部34(密封本体)相垂直。
凸起342与密封部34(密封本体341)相垂直或大致相垂直,即凸起342与密封部34的连接处呈L形。当密封部34(密封本体341)贴合在内锅2的上表面上、凸起342闭合腔体4时,凸起342与密封部34(密封本体341)相垂直或大致垂直的结构,能够减小凸起342的长度,从而减小密封环3上与内锅2内的高温高湿环境的接触面积,同时对密封本体341的加强效果良好。
在第一个具体的实施例中,合盖状态下凸起342抵接在盖体1上或抵接在支撑部32上或抵接在支撑部32与连接部31的连接处。
凸起342连接在密封本体341的末端,合盖状态下凸起342抵接在盖体1上形成密封空腔5,使得合盖状态下只有凸起342的外侧表面与内锅2内的高温高湿环境相接触;或者,凸起342抵接在支撑部32上形成密封空腔5;或者,凸起342抵接在支撑部32与连接部31的连接处形成密封空腔5,优选地,应合理设置凸起342与支撑部32和连接部31的连接处的抵接位置,尽量减小支撑部32位于内锅2内的部分,减少支撑部32与内锅2内的高温高湿环境的接触面积。
在第二个具体地实施例中,连接部31或连接部31与支撑部32的连接处向靠近盖体1轴线的方向延伸形成延伸部35,延伸部35贴合在盖体1的下表面上,合盖状态下凸起342抵接在延伸部35上。
合盖状态下密封部34与延伸部35相抵接形成密封空腔5,具体地,连接部31或连接部31与支撑部的连接处向靠近盖体1轴线的方向延伸形成延伸部35,延伸部35贴合在盖体1的下表面上,优选地,盖体1包括活动盖板,延伸部35抵接在活动盖板的下表面上,凸起342连接在密封本体341的末端,合盖状态下凸起342抵接在延伸部35上。
优选地,如图4所示,凸起342和延伸部35的抵接处与延伸部35的自由端之间的距离W为0mm~3mm。
优选地,合盖状态下密封部34沿水平方向设置;或者,如图13所示,合盖状态下沿由外向内的方向密封部34向上倾斜形成第一倾斜面344,内锅2的上表面上与第一倾斜面344相对应处形成与第一倾斜面344相适配的第二倾斜面221。合盖状态下密封部34沿水平方向设置或形成第一倾斜面344,在开盖状态下,密封部34可以呈水平方向设置或密封部34上设有第一倾斜面344,或者,密封部34沿其它方向设置,在合盖力的作用下,在合盖状态下沿水平方向设置或形成第一倾斜面344。
合盖状态下,密封部34水平设置,内锅2的上表面上与密封部34相贴合处可以是水平面,也可以是由内向外向上或向下倾斜的倾斜面,但合盖状态下通过调整密封环3的压缩量等以保证密封部34的至少部分贴合在内锅2的上表面上。或者,合盖状态下沿由外向内的方向密封部34向上倾斜,形成第一倾斜面344,为保证内锅2的上表面与第一倾斜面344的良好贴合,内锅2的上表面上与第一倾斜面344相对应处形成第二倾斜面221,优选地,第二倾斜面221的倾斜角度与第一倾斜面344的倾斜角度一致。当合盖状态下沿由外向内的方向密封部34向上倾斜形成第一倾斜面344时,在开盖状态,密封部34可以沿水平方向设置,也可以沿由外向内的方向密封部34向上倾斜。当然,密封环上可以只有密封部34与锅沿32相贴合(如图11所示)或密封部34和压缩部均与锅沿32相贴合(如图12所示)。
优选地,如图11至图13所示,内锅2包括锅本体21和锅本体21向外周向延伸形成的锅沿32,合盖状态下密封部34不凸出锅本体21与锅沿32连接处的外边缘。锅本体21上设有锅沿32或不设置锅沿32,在设置锅沿32时,内锅2的内壁面包括锅本体21的内壁面和锅本体21与锅沿32连接处,因此,密封部34不凸出内锅2的内壁面指的是密封部34不凸出锅本体21与锅沿32连接处的外边缘。
为保证合盖状态下密封部34不与内锅2内的高温高湿环境相接触,密封部34不凸出锅本体21与锅沿32连接处的外边缘,即密封部34可以与锅本体21与锅沿32连接处的外边缘相平齐或位于锅本体21与锅沿32连接处的外边 缘的外侧。如图14所示,密封部向内凸出锅本体与锅沿连接处的外边缘,使得密封部的一部分位于内锅内,增大了密封环上与内锅内的高温高湿环境的接触面积。
优选地,如图11至图13所示,锅本体21与锅沿32的连接处设有过渡圆弧23,合盖状态下密封部34不凸出过渡圆弧23的外边缘。
当然,锅本体21与锅沿32的连接处也可以不设置过渡圆弧23,使得锅本体21与锅沿32的连接处呈直角,此时,合盖状态下密封部34不凸出锅本体21与锅沿32的直角连接处。
优选地,盖体1包括内盖,活动盖板通过压圈6能够拆卸地安装在内盖上,且活动盖板位于压圈6的内侧。密封环3通过压圈6和活动盖板进行固定,具体地,连接部31被压设或被夹持在活动盖板和压圈6之间。密封环3在盖体1上的装配方式属于成熟的技术,不再详述。
烹饪器具为电饭煲或电压力锅。
综上所述,本发明实施例提供的密封环3,在合盖时,压缩部与内锅相贴合,并带动密封部向靠近腔体开口端的方向运动,以使合盖状态密封部密封腔体的开口端,形成密封空腔,相比于相关技术中需要单独设置用于密封腔体的密封部位相比,通过增大压缩量,使得密封环3本身带有的密封部密封腔体,简化了密封环3的结构,且形成密封空腔后减少了冷凝水的形成。
