一般蒸汽发生器运作时的功率存在波动,导致蒸汽发生器产生蒸汽的稳定性较差,但是洗碗机一般直接与市电连通,要实现功率的稳定性难度较大,耗费较高。而本案使用过程中通过所述温度检测件121检测所述蒸汽发生器12的温度,所述流量控制单元141根据所述温度检测件121获得的温度值调整所述进水管14的导通量,从而调整进入所述蒸汽发生器12中的水量,避免所述蒸汽发生器12中水量过低导致蒸汽发生器12烧干,或者水量过高导致无法迅速使水形成蒸汽的情况发生,最终保障蒸汽发生器12产生蒸汽的稳定性,降低洗碗机10不良率。
具体地,在一个实施例中,所述温度检测件121设置在所述蒸汽发生器12的壳体上,被设置为检测所述蒸汽发生器12的壳体温度。即通过获取所述蒸汽 发生器12的壳体温度,判断所述蒸汽发生器12中水量是否符合要求。
在一些实施方式中,也可以通过检测所述蒸汽发生器12其他位置的温度,只要能够反应所述蒸汽发生器12中蒸汽形成情况,以及水量情况即可。
所述温度检测件121可以是温度传感器,或者是其他能够检测温度的器件,在这里不做具体限制。
具体地,所述温度检测件121可以设置在所述蒸汽发生器12的壳体内侧,从而提高检测的精度。
在一些实施方式中,在一个实施例中,如图1所示,所述进水管14上设有水泵142,所述水泵142位于所述流量控制单元141的上游,所述水泵142与所述流量控制单元141和所述温度检测件121均电性连接。

具体地,若将水流量调节过程分为粗调过程和微调过程,则在粗调过程中可以利用所述水泵142直接控制所述进水管14中流量大小,在微调过程中可以利用所述流量控制单元141协同实现,提高调节的精度。
具体地,在一个实施例中,如图2所示,所述流量控制单元141为用于调节所述进水管14中流量大小的流量控制阀,所述流量控制阀包括阀体1411、阀芯1412、阀芯齿轮1413、电机1414和电机齿轮1415。所述阀体1411的进口和出口分别连通在所述进水管14上,所述阀芯1412设置在所述阀体1411中,所述阀芯齿轮1413与所述阀芯1412连接,被设置为带动所述阀芯1412转动,所 述电机1414的转轴与所述电机齿轮1415连接,被设置为带动所述电机齿轮1415转动,所述电机齿轮1415与所述阀芯齿轮1413啮合,所述电机1414与所述温度检测件121电性连接。
所述电机1414根据所述温度检测件121检测到的温度值调整转动方向和转速,从而控制所述电机齿轮1415转动,进而调整所述阀芯齿轮1413转动,实现对所述阀芯1412的控制。从而调整所述阀芯1412在所述阀体1411中的位置,改变所述阀体1411中流道的截面积,调整流量。
当所述洗碗机10中设有所述水泵142时,也可以将所述电机1414与所述水泵142电性连接,实现所述水泵142与所述电机1414的协同配合。
具体地,所述水泵142、电机1414以及所述温度检测件121之间的电性连接可以是直接电性连接,也可以是间接电性连接。
例如,在一个实施例中,所述洗碗机10还包括控制器15,所述控制器15设有相互电性连接的比较模块和执行模块。所述比较模块与所述温度检测件121电性连接,被设置为比较所述温度检测件121检测的温度值与预设的允许温度范围之间的关系,所述执行模块与所述流量控制单元141电性连接。
从而当所述温度检测件121检测的温度值传输给所述比较模块后,所述比较模块将比较结果输送给所述执行模块,所述执行模块根据接收到的比较结果控制所述流量控制单元141运作。
当所述流量控制单元141包括所述电机1414时,所述执行模块与所述电机1414电性连接,直接控制所述电机1414正转或反转。当所述洗碗机10包括所述水泵142时,所述控制器15也与所述水泵142电性连接,控制所述水泵142的启停。
具体地,在一个实施例中,所述比较模块比较所述温度检测件121检测的 温度值与预设的允许温度范围之间的关系时,所述允许温度范围的最大值为120℃,所述允许温度范围的最小值为102℃。若所述温度检测件121检测的温度值大于120℃,则所述执行模块控制所述流量控制单元141调大,使得进入所述蒸汽发生器12中的水流量增加;当温度检测件121检测的温度小于102℃时,所述执行模块控制所述流量控制单元141调小,使得进入所述蒸汽发生器12中的水流量减小。
在一些实施方式中,在一个实施例中,如图1所示,所述洗碗机10还包括储水装置11,所述进水管14连通在所述储水装置11与所述蒸汽发生器12的进水口之间,所述储水装置11的入水口设有入水总管路16,所述入水总管路16上设有第一开关阀161。控制所述储水装置11中的水量,当需要向所述储水装置11中供水时,所述第一开关阀161开启。
所述储水装置11与所述内胆13之间设有辅助管路,所述辅助管路上设有第二开关阀17。所述储水装置11中的水可以经过所述辅助管路直接进入所述内胆13中,为洗涤过程供水。
在一些实施方式中,如图1所示,所述内胆13中还设有餐具篮131和喷头132。待洗涤的餐具20则放置在所述餐具篮131中,所述喷头132则对所述餐具20进行喷淋。所述喷头132与内胆13的腔体之间还设有循环管路,所述循环管路能够将所述内胆13腔体中的洗涤水再次导入所述喷头132中。所述循环管路上设有洗涤泵133用于为所述循环管路中的水提供动力。所述循环管路上设有加热器134,为循环从所述喷头132喷出的水加热。
所述内胆13的底部设有排水管135,所述排水管135上设有排水泵136,被设置为将内胆13中的洗涤水排出。
在一些实施方式中,如图3所示,在另一个实施例中,提供了一种洗碗机 控制方法,包括以下步骤:
获取与洗碗机10内胆13导通的蒸汽发生器12的温度T,并判断温度T与预设的允许温度范围之间的关系;
若温度T大于所述允许温度范围的最大值Tmax,则增大进入所述蒸汽发生器12的水流量;
若温度T小于所述允许温度范围的最小值Tmin,则减小进入所述蒸汽发生器12的水流量。
上述方案提供了一种洗碗机控制方法,通过获取所述蒸汽发生器12的温度T,并比较温度T与允许温度范围之间的关系,当蒸汽发生器12的温度T大于允许温度范围的最大值Tmax时,证明所述蒸汽发生器12的温度过高,若持续下去将导致蒸汽发生器12烧坏的情况发生,因此增大进入所述蒸汽发生器12的水流量。当蒸汽发生器12的温度T小于允许温度范围的最小值Tmin时,蒸汽发生器12无法将其中的水迅速加热为蒸汽,将会存在水谁在蒸汽发生器12中沸腾膨胀,部分水被膨胀压力喷出的情况发生,因此调小进入所述蒸汽发生器12的水流量。从而确保所述蒸汽发生器12能够形成稳定蒸汽,降低不良率。
具体地,在一个实施例中,获取的所述蒸汽发生器12的温度T为所述蒸汽发生器12的壳体温度。
在一些实施方式中,也可以获取所述蒸汽发生器12的其他位置的温度,只要其能够反应所述蒸汽发生器12中水量情况即可。
在一些实施方式中,在一个实施例中,如图3所示,若温度T位于最大值Tmax与最小值Tmin之间,则证明此时所述蒸汽发生器12中的水量适宜,可以维持当前进入所述蒸汽发生器12的水流量。即保持当前所述蒸汽发生器12的单位时间进水量。
在一些实施方式中,在一个实施例中,所述最大值Tmax为120℃,所述最小值Tmin为102℃。
当所获取的所述蒸汽发生器12的壳体温度大于120℃时,增大进入所述蒸汽发生器12的水流量。当获取的蒸汽发生器12的壳体温度低于102℃,减小进入所述蒸汽发生器12的水流量。
在一些实施方式中,在一个实施例中,调节进入所述蒸汽发生器12的水流量大小的过程包括微调过程和粗调过程,所述微调过程中水流量小于粗调过程中水流量;当单位时间内所述蒸汽发生器12的温度T波动大于预设温度波动率△H时,采用粗调过程;当单位时间内所述蒸汽发生器12的温度T波动小于预设温度波动率△H时,采用微调过程。
当单位时间内所述蒸汽发生器12的温度T波动大于预设温度波动率△H,证明此时所述蒸汽发生器12的温度波动较大,可以快速调整所述蒸汽发生器12中的水量,使得蒸汽发生器12的温度恢复到允许温度范围内,采用粗调过程。当单位时间内所述蒸汽发生器12的温度T波动小于预设温度波动率△H时,通过微调使得蒸汽发生器12的温度维持在相对稳定状态。
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公开的几种实施方式,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,在不脱离本公开构思的前提下,还可以做出若干变形和改进,这些都属于本公开的保护范围。因此,本公开专利的保护范围应以所附权利要求为准。
