Description

一种平衡式污染物清洁***
本申请要求于2019年4月22日提交中国专利局、申请号为CN201910325023.2申请名称为平衡式污染物清洁***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
本申请实施例涉及烟气收集装置领域，具体涉及一种平衡式污染物清洁***。
背景技术
在日常生活中，家里的客厅、卧室都会安装空调，这样夏天就不会被炎热所困扰，冬天也不会被寒冷所扰。随着家居环境不断改善和人们对生活质量的完美追求，厨房安装空调问题越来越受到人们的关注。目前，厨房空调市场需求巨大，但真正购买者却不多，原因值得深思。比如在南方，夏天4月到10月厨房工作温度平均在33度以上。然而由于厨房的油烟多，严重影响了厨房空调的使用效果和寿命。由于没有对灶台发出的油烟和热量进行阻隔，油烟和热量依然会扩散至厨房其它角落，因此只能通过提高油烟机的功率来减小油烟和热量的扩散，但是这样会进一步增加耗电量，且效果不明显。此外，即使厨房里安装了空调，油烟机在工作时会将大量的室内冷空气排出，并使室外的热空气对流进入厨房，使厨房里的温度迅速升高。同样的，对于冬天开暖气的厨房，由于油烟机将大量的热空气排出室外，冷空气对流进入厨房，从而使厨房的温度迅速降低，厨房里跟室外一样寒冷，因此现有的油烟机对厨房内的温度影响大，厨房空调或者暖气设备并不能发挥其正常的功效。
申请内容
为此，本申请实施例提供一种平衡式污染物清洁***，以解决现有的厨房设备存在油烟排净率低，能耗高，以及对厨房内的温度影响大的问题。
为了实现上述目的，本申请实施例提供一种平衡式污染物清洁***，所述平衡式污染物清洁***包括：
风机；
喷气装置，所述喷气装置设置于被屏蔽物体的外周，所述喷气装置上设置有多个喷气口，所述喷气装置的进气口与所述风机的出气口通过管线连接，当所述喷气口喷气时，喷出的气流在被屏蔽物体的外周形成一圈风帘；
吸气装置，所述吸气装置设置于所述被屏蔽物体的上方，所述吸气装置用于吸走被屏蔽物体产生的污染物和热量，以及所述喷气口喷出的空气；
控制装置，所述控制装置用于控制所述风机输出的气流大小，并根据所述风机输出的气流大小调节所述吸气装置的吸气量。
进一步地，所述吸气装置为油烟机。
进一步地，所述控制装置包括控制模块、气体流量计、电压控制器和调速按键，所述控制模块分别与气体流量计、电压控制器、调速按键、油烟机的驱动线路板电连接，所述电压控制器与所述风机电连接。
进一步地，所述控制模块为单片机。
进一步地，相邻两个所述喷气口之间的距离相等。
进一步地，所述被屏蔽物体为燃气灶。
进一步地，所述气体流量计的型号为HQLUGB。
进一步地，所述单片机的型号为STM8S103。
本申请实施例具有如下优点：
1、本申请实施例的平衡式污染物清洁***通过喷气装置进行喷气，从而在燃气灶的四周形成一圈风帘，将烹饪时产生的热量和油烟阻隔在风帘内并最终通过吸气装置排走，从而提高了热量和油烟的排净率，同时通过风帘将油烟与厨师进行有效隔离，减小油烟对厨师身体造成的伤害。
2、本申请实施例的平衡式污染物清洁***通过控制装置控制风机输出的气流大小，并根据风机输出的气流大小调节吸气装置的吸气量，可有效减小能耗；由于风帘将风帘内的空气与厨房内的空气阻隔开(风帘的作用与商场风幕机的作用相同)，因此不管是冬天供暖还是夏天开空调，厨房内的空气都不会受油烟机影响(冷气或者暖气不会被抽走排出，不需要增加更多的冷气或者暖气来补充)，因此更加节能。

具体实施方式
以下由特定的具体实施例说明本申请的实施方式，熟悉此技术的人士可由本说明书所揭露的内容轻易地了解本申请的其他优点及功效，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
如图1所示，平衡式污染物清洁***包括风机10、喷气装置20、吸气装置30和控制装置，风机10用于为喷气装置20提供稳定的空气流。本实施例的喷气装置20由四根中空管21首尾依次连接构成，喷气装置20设置于被屏蔽物体50的外周，本实施例中的被屏蔽物体50为燃气灶，喷气装置20呈矩形，当然，喷气装置20的形状并不限定于此，具体根据被屏蔽物体50的形状确定。每根中空管21的外周面上向上设置有多个喷气口22，优选的，相邻两个喷气口22之间的距离相等。本实施例中的其中一根中空管21设置有进气口，进气口与风机10的出气口通过管线连接，当然也可在每根中空管21设置进气口并将其与风机10的出气口单独连接。由于四根中空管21的内部是连通的，因此其内部压力相等，从而确保每个喷气口22喷出气流的流速也是相等的，当喷气口22喷气时，喷出的气流在燃气灶的外周形成一圈风帘。
如图2所示，吸气装置30用于吸走被屏蔽物体50产生的污染物和热量，以及喷气口22喷出的空气，吸气装置30设置于被屏蔽物体50的上方，本实施例中吸气装置30为油烟机，油烟机通过螺栓固定安装于墙体上，并处于燃气灶的正上方。油烟机的尺寸大于风帘围成的面积，以确保将 产生的热量和油烟全部吸走，提高热量和油烟的排净率。
如图3所示，控制装置用于控制风机10输出的气流大小，并根据风机10输出的气流大小调节吸气装置30吸气量。控制装置包括控制模块41、气体流量计42、电压控制器43和调速按键44，控制模块41分别与气体流量计42、电压控制器43、调速按键44、油烟机的驱动线路板电连接，电压控制器43与风机10电连接。控制模块41在本实施例中为单片机，单片机的型号为STM8S103，该型号的单片机兼容性较好，可以与目前市场上大多数油烟机的驱动线路板相兼容。气体流量计42用于测量风机10输出气流的实时流量，并将其转化成电信号发送至控制模块41，气体流量计42安装于风机10的出气口，本实施例中的气体流量计42的型号为HQLUGB，该型号的气体流量计42具有精度高和体积小的优点。调速按键44用于向控制模块41发送流量调节指令，控制模块41接收到流量调节指令后向电压控制器43发送电压调节指令，电压控制器43接收到电压调节指令后通过改变输出给风机10的电压来改变风机10的输出功率，进而改变风机10输出的气流大小。
烹饪时，打开油烟机的同时打开风机10，风机10输的气流通过每一个喷气口22均匀喷出，喷出的气流在燃气灶的四周形成一圈风帘，将烹饪时产生的热量和油烟阻隔在风帘内并最终通过吸气装置30排走，从而提高了热量和油烟的排净率，同时通过风帘将油烟与厨师进行有效隔离，减小油烟对厨师身体造成的伤害。若在使用过程中，风帘不足以完全将燃气灶产生的油烟和热量阻隔，可通过按压调速按键44增大喷气口22喷出的气流大小，控制模块41根据气体流量计42测量的流量大小增大油烟机的吸气量，实现闭环控制，从而将热量和油烟彻底阻隔于风帘内，通过控制装置控制风机10输出的气流大小，并根据风机10输出的气流大小调节吸气装置30的吸气量，可有效减小能耗；由于风帘将风帘内的空气与厨房内的空气阻隔开(风帘的作用与商场风幕机的作用相同)，因此不管是冬天供暖还是夏天开空调，厨房内的空气都不会受油烟机影响(冷气或者暖气不会被抽走排出，不需要增加更多的冷气或者暖气来补充)， 因此更加节能。
虽然，上文中已经用一般性说明及具体实施例对本申请作了详尽的描述，但在本申请基础上，可以对之作一些修改或改进，这对本领域技术人员而言是显而易见的。因此，在不偏离本申请精神的基础上所做的这些修改或改进，均属于本申请要求保护的范围。
