Description

微波加热装置 技术领域
本发明涉及电器技术领域，尤其是涉及一种微波加热装置。
背景技术
相关技术中的抽屉式微波炉，采用以下两种方法来检测抽屉门开关是否到位：一是利用收集及计算整个行程中的脉冲信号的数量进行判断，二是根据特定的时间内收集到的脉冲信号的数量进行判断。然而，第一种方法容易受到外界环境的影响而失效，例如停电、电压波动或是外部信号干扰等影响，导致抽屉式微波炉的可靠性差；第二种方法增加了电机的负载，导致电机易烧毁损坏，寿命短。此外，以上两种方法由于需要电机收集和反馈脉冲信号，使得电机结构复杂，电机的工艺要求和品质要求高，导致抽屉式微波炉的成本较高。

具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本发明，而不能理解为对本发明的限制。
下面参考图1-图9描述根据本发明实施例的微波加热装置100，所述微波加热装置100利用微波对食物进行加热，能够实现抽屉的自动打开或关闭，具有结构简单、可靠性高、成本低等优点。
具体地，微波加热装置100可以为嵌入在墙壁或橱柜中的微波炉或微波烤箱。
如图1-图9所示，根据本发明实施例的微波加热装置100，包括炉身1、抽屉门2、驱动装置3以及控制器43。
炉身1内具有微波加热腔10，食物在微波加热腔10中被加热。炉身1上设有关门检测开关15和开门检测开关12，抽屉门2上设有开门触动结构21和关门触动结构22，抽屉门2在打开微波加热腔10的打开位置和关闭微波加热腔10的关闭位置之间可移动地安装在炉身1上，由此用户可以方便地将食物放入微波加热腔10内进行加热，或从 微波加热腔10内取出食物。例如，将食物放入抽屉后，使抽屉门2在如图2所示的打开位置向后移动，直到抽屉门2移动到如图4所示的关闭位置，抽屉门2完全关闭微波加热腔10，此时微波加热装置100可以对食物进行加热；食物加热完成后，使抽屉门2在如图所示的关闭位置向前移动，直到抽屉门2移动到如图2所示的打开位置，微波加热腔10被最大程度地打开，此时可以将食物取出。
如图6-图7所示，抽屉门2位于打开位置时，开门触动结构21触动开门检测开关12，且关门触动结构22释放关门检测开关15，这样，抽屉门2在打开位置时的位置能够被检测到，且检测到的抽屉门2的位置的准确性高。如图4-图5所示，抽屉门2位于关闭位置时关门触动结构22触动关门检测开关15，且开门触动结构21释放开门检测开关12，这样，抽屉门2在关闭位置时的位置能够被检测到，且检测到的抽屉门2的位置的准确性高。
驱动装置3用于驱动抽屉门2在打开位置和关闭位置之间移动，驱动装置3安装在炉身1和抽屉门2中的一个上且与另一个传动相连，由此驱动装置3得以支撑，从而能够驱动抽屉门2的移动。例如，如图2所示，驱动装置3安装在炉身1的底部，且驱动装置3与抽屉门2传动相连，抽屉门2在驱动装置3的驱动下可以前后移动。当然，驱动装置3还可以设在抽屉门2上并与炉身1传动相连。需要说明的是，这里驱动装置3与炉身1和抽屉门2中的上述另一个传动相连，至少包括驱动装置3能够使得炉身1和抽屉门2之间产生相对运动的情形。
控制器43分别与开门检测开关12、关门检测开关15和驱动装置3通讯，从而实现抽屉门2的自动打开或关闭。
下面参照附图以抽屉门2的初始位置是关闭位置为例详细描述根据本发明实施例的微波加热装置100的工作过程。可以理解的是，此时开门触动结构21释放开门检测开关12。
当需要加热食物时，控制器43与驱动装置3通讯并使驱动装置3驱动抽屉门2向前移动，抽屉门2在向前移动的过程中逐渐打开微波加热腔10，当抽屉门2移动至如图2和图6所示的打开位置时，微波加热腔10被最大程度地打开，开门触动结构21触动开门检测开关12，且关门触动结构22释放关门检测开关15，这样驱动装置3停止工作，用户可以将食物放入抽屉内。之后，控制器43与驱动装置3通讯并使驱动装置3驱动抽屉门2向后移动，抽屉门2在向后移动的过程中逐渐关闭微波加热腔10，当抽屉门2移动至如图4所示的关闭位置时，微波加热腔10被完全关闭，关门触动结构22触动关门检测开关15，且开门触动结构21释放开门检测开关12，这样驱动装置3停止工作，此时微波加热装置100可以对食物进行加热。可以理解的是，当食物加热完成后，重复如上所述的步骤即可取出食物后再关闭抽屉门2。
根据本发明实施例的微波加热装置100，利用抽屉门2位于打开位置时开门触动结构21触动开门检测开关12且关门触动结构22释放关门检测开关15，抽屉门2位于关闭位置时关门触动结构22触动关门检测开关15且开门触动结构21释放开门检测开关 12，能够自动检测抽屉门2的位置，且检测的准确性高，从而实现了抽屉门2的自动打开或关闭，采用机械式检测，受外界因素影响小，工作可靠性高。此外，由于无需利用驱动装置3收集脉冲信号，因此可以采用结构简单、成本低廉的驱动装置3，而且不增加驱动装置3的负载，从而简化了微波加热装置100的结构，降低了生产成本，改善了使用寿命。
如图2和图6所示，根据本发明的一些实施例，炉身1的左右两侧可以设有导轨13，抽屉门2的左右两侧设有导轨连接板23，导轨连接板23可移动地配合在导轨13上，这样抽屉门2在前后方向上能够平稳地移动。
可选地，如图2、图4和图5-图7所示，开门触动结构21可以为设在导轨连接板23上的限位块，关门触动结构22可以为设在抽屉门2上的门钩。其中限位块可以位于导轨连接板23的后端，这样抽屉可以较大程度地移出微波加热腔10，用户取放食物更加方便，且可保证抽屉门2在打开空间足够大的情况下稳定支撑在导轨13上，有效延长了抽屉们2和导轨13的使用寿命。门钩从抽屉门2朝向后方延伸，从而微波加热装置100能够准确检测抽屉门2完全关闭微波加热腔10时的位置。
进一步地，如图2-图7所示，炉身1上可以设有联锁支架14，开门检测开关12和关门检测开关15安装在联锁支架14上，其中，如图4-图5所示，抽屉门2位于关闭位置时门钩钩挂在联锁支架14上，如此保证门钩能够不脱离关门检测开关15，且抽屉门2的位置稳定。如图6-图7所示，抽屉门2位于打开位置时限位块被联锁支架14止挡，这样，可以防止抽屉门2脱落，且保证限位块能够触动开门检测开关12。可选地，如附图中，门钩可以为大体“L”形，有利于门钩牢靠地钩挂在联锁支架14上。
在如图2-图5所示的实施例中，关门检测开关15可以包括分别与控制器43通讯的监控开关111、初级开关112和次级开关113，抽屉门2位于关闭位置时关门触动结构22分别触动监控开关111、初级开关112和次级开关113，此时控制器43通讯驱动装置3以使驱动装置3停止工作，抽屉门2位于打开位置时关门触动结构22分别释放监控开关111、初级开关112和次级开关113，避免影响控制器43与驱动装置3的通讯，提高电控的安全性。
在本发明的进一步实施例中，初级开关112可以为两个，监控开关111和一个初级开关112设在炉身1的左部，次级开关113和另一个初级开关112设在炉身1的右部，关门触动结构22为两个且分别设在抽屉门2的左部和右部，其中，抽屉门2位于关闭位置时，位于抽屉门2左部的关门触动结构22分别触动监控开关111和上述一个初级开关112，位于抽屉门2右部的关门触动结构22分别触动次级开关113和上述另一个初级开关112，抽屉门2位于打开位置时，位于抽屉门2左部的关门触动结构22分别释放监控开关111和一个初级开关112，位于抽屉门2右部的关门触动结构22分别释放次级开关113和另一个初级开关112。由此，提高了控制器43的通讯可靠性和抽屉门2的位置的检测准确性。
也就是说，如附图中，炉身1的左侧设有监控开关111和初级开关112，炉身1的 右侧设有次级开关113和初级开关112，抽屉门2的左右两侧各设有一个门钩，当抽屉门2位于关闭位置时，抽屉门2左侧的门钩触动监控开关111，且触动炉身1左侧的初级开关112，抽屉门2右侧的门钩触动次级开关113，且触动炉身1右侧的初级开关112，当抽屉门2位于打开位置时，抽屉门2左侧的门钩释放监控开关111，且释放炉身1左侧的初级开关112，抽屉门2右侧的门钩释放次级开关113，且释放炉身1右侧的初级开关112。
可选地，如图2-图7所示，监控开关111和位于炉身1左侧的初级开关112均水平设置，且炉身1左侧的初级开关112位于监控开关111的下方。次级开关113竖向设置，且炉身1右侧的初级开关112水平设置且位于次级开关113的下方。作为优选，监控开关111、初级开关112、次级开关113和开门检测开关12可以均为微动开关，使得微波加热装置100的控制简单，反应迅速。
如图2所示，根据本发明的一个实施例，驱动装置3可以包括电机31和推杆器32，其中电机31安装在炉身1的底部，控制器43与电机31通讯，这样当需要打开或关闭抽屉门2时，控制器43能够控制电机31正转或反转。推杆器32分别与电机31和抽屉门2相连，推杆器32将电机31的旋转运动转化为抽屉门2的线性运动。由此，当需要打开抽屉门2时，控制器43与电机31通讯并使电机31旋转，在推杆器32的作用下电机31的旋转运动转化为抽屉门2向前的移动，从而抽屉门2被打开，当需要关闭抽屉门2时，在推杆器32的作用下电机31的旋转运动转化为抽屉门2向后的移动，从而抽屉门2被关闭。
进一步地，如图2和图9所示，推杆器32可以包括主动带轮322、从动带轮323、推杆传动带324以及推杆321。其中，主动带轮322和从动带轮323分别可旋转地安装在炉身1上，电机31与主动带轮322传动连接，推杆传动带324套设在主动带轮322和从动带轮323上，电机31驱动主动带轮322旋转以带动推杆传动带324运动，从而推杆传动带324带动从动带轮323旋转。推杆321分别与推杆传动带324和抽屉门2相连，推杆321在推杆传动带324的带动下线性运动以带动抽屉门2在打开位置和关闭位置之间移动。
可选地，如图8和图9所示，驱动装置3还可以包括变速传动组件33，电机31通过变速传动组件33与主动带轮322传动连接，这样电机31的转动能够通过变速传动组件33传递给主动带轮322，从而能够改变主动带轮322的转速，进而调节抽屉门2的移动速度。
进一步地，如图8和图9所示，变速传动组件33可以包括电机带轮331、变速带轮332和变速传动带333，电机带轮331与电机31传动连接，变速带轮332与主动带轮322传动连接，变速传动带333套设在电机带轮331和变速带轮332上，这样电机31带动电机带轮331旋转，变速传动带333在电机带轮331的带动下带动变速带轮332转动，从而变速带轮332带动主动带轮322旋转。通过设置电机带轮331和变速带轮332的尺寸比，实现变速传动。
下面参考附图详细描述根据本发明的一个具体实施例的微波加热装置100，值得理解的是，下述描述只是示例性说明，而不能理解为对本发明的限制。
如图1-图9所示，根据本发明实施例的微波加热装置100，包括炉身1、抽屉门2、驱动装置3以及控制器43。
具体而言，炉身1内具有微波加热腔10。炉身1的后侧设有微波发射器5、变压器41、电容42与风扇组件7，其中变压器41与电容42适用于支撑微波发射器5，风扇组件7能够对微波加热装置100进行散热。炉身1的顶部设有波导管6，用于将微波导入到微波加热腔10内。炉身1的左右两侧分别设有联锁支架14，关门检测开关15和开门检测开关12安装在联锁支架14上且均为微动开关，其中关门检测开关15包括监控开关111、初级开关112和次级开关113，左侧的联锁支架14上设有水平设置的监控开关111和初级开关112，初级开关112位于监控开关111的下方，右侧的联锁支架14上设有次级开关113、初级开关112和开门检测开关12，次级开关113竖向设置，初级开关112水平设置且位于次级开关113的下方、开门检测开关12的上方。
抽屉门2可前后移动地设在微波加热腔10内，炉身1的左右两侧分别固定一根导轨13，对应地在抽屉门2的左右两侧分别设有导轨连接板23以配合在导轨13内，从而达到支撑抽屉门2的滑动的作用，同时，在抽屉门2的后端还固定有滚轮，以方便抽屉门2轻松滑动。抽屉门2的前端设有控制面板24，控制面板24上设有控制微波加热装置100工作情况的按键。抽屉门2上设有开门触动结构21和关门触动结构22，开门触动结构21为设在左侧导轨连接板23后端的限位块，关门触动结构22为设在抽屉门2后表面的左右两侧的门钩。
炉身1的底部安装有驱动装置3，驱动装置3包括电机31和推杆器32，推杆器32能将电机31的旋转运动转换为推杆321的前后移动，这样，推杆器32由电机31驱动，推杆321与抽屉门2连接，从而只需用户在控制面板24上，按下相应的“打开”或“关闭”按键即可以控制抽屉门2的打开与关闭。控制器43为位于炉身1后侧的电脑板，控制器43分别与开门检测开关12、关门检测开关15和驱动装置3通讯。
在抽屉门2上设有门钩，当抽屉门2关闭时，门钩扣紧联锁支架14，此时机器便可烹饪食物了。
微波加热装置100工作时，用户按下控制面板24上的“打开”按键，控制器43得到指令后，便会发出信号控制电机31正转，电机31的转动通过推杆器32转化为推杆321向前的移动，从而打开抽屉门2。当抽屉门2打开到设定的最大行程时，限位块会压下开门检测开关12，这时开门检测开关12反馈信号，控制器43判断抽屉门2打开到位，从而使驱动装置3停止工作，抽屉门2停止移动。当用户将食物放入到抽屉门2内后，按下控制面板24上的“关闭”按键，控制器43会发出信号控制电机31反转，推杆器32便会控制推杆321往后移动，控制抽屉门2关上。将抽屉门2关闭后，左右两侧的门钩触碰到联锁支架14上的监控开关111、初级开关112和次级开关113，监控开关111、初级开关112和次级开关113反馈信号给控制器43，控制器43判断抽屉门2 关闭到位，从而使驱动装置3停止工作，抽屉门2停止移动。此时，用户便可根据自己的要求，选择相应的烹饪功能。
根据本发明实施例的微波加热装置100，利用机械方式定位来判断抽屉门2的位置，实现自动打开或关闭抽屉门2，工作可靠，且结构简单、成本低，使用寿命长。
