背景技术Background technique
生活中,在每次烹饪结束后需要对锅具进行冲洗清理,清洗后锅具内经常残留水分,若不及时进行清理,在残留水分的作用下,锅具很容易生锈。为了避免锅具生锈在每次清洗后需要通过抹布对锅具进行擦拭,擦干锅具上残留的水分。实际应用中还可以通过再次加热,或者将锅具竖直放置,以去除锅具中残留的水分。可见,现有方法不仅为使用者带来不便,而且由于在每次烹饪结束后,锅具具有余热,也有可能烫伤使用者。In life, it is necessary to rinse and clean the pot after each cooking. After cleaning, water often remains in the pot. If it is not cleaned in time, the pot will easily rust under the action of the residual water. In order to avoid the rust of the cookware, it is necessary to wipe the cookware with a rag after each cleaning, and wipe off the residual water on the cookware. In practice, it can also be heated again, or the pot is placed upright to remove the residual moisture in the pot. It can be seen that the existing method not only causes inconvenience to the user, but also may cause burns to the user due to the residual heat of the pot after each cooking.
为了避免锅具生锈,可以通过在锅具内表面设置涂层,如聚四氟乙烯,阻止锅具材料与空气以及残留的水接触。但在锅具表面的涂层,很容易在烹饪过程中被损坏,因此使用者不得不使用木质锅铲或塑料锅铲,同样带来不便。另外,如果锅具上的涂层品质低劣,在个别高温、酸性条件环境下,会分解产生有害物质,影响食品健康。In order to avoid the rust of the cookware, it is possible to prevent the pot material from contacting the air and the residual water by providing a coating on the inner surface of the pot, such as PTFE. However, the coating on the surface of the pot is easily damaged during the cooking process, so the user has to use a wooden spatula or a plastic spatula, which is also inconvenient. In addition, if the coating on the cookware is of poor quality, under certain high-temperature and acidic conditions, it will decompose to produce harmful substances, affecting food health.

The cooking utensils 4 will generate oil fumes during the cooking process. The oil fumes spread upward and around to reach the location near the smoking port 21, and can be discharged outside the room with the air flow in the smoke exhaust duct 2 to achieve the effect of absorbing the oil fumes.
为了加快锅具4上残留的水分蒸发,本申请提供的所述吸油烟机的排烟管道2上设有电动百叶窗23,电动百叶窗23可以设置在排烟管道2的吸烟口21位置,电动百叶窗23可封堵吸烟口21,并且所述吸油烟机还包括吹风管道5以及控制器6。其中,电动百叶窗23可以是设置在吸烟口21位置上的多个叶片形部件,通过百叶窗中的每个叶片结构的翻转可以实现对吸烟口21通道进行开关。In order to speed up the evaporation of the residual moisture on the cooker 4, the smoke exhaust duct 2 of the range hood provided by the present application is provided with electric shutters 23, which can be arranged at the position of the smoking port 21 of the smoke exhaust duct 2, and the electric shutters 23 can block the smoking port 21, and the range hood further includes a blowing duct 5 and a controller 6. Wherein, the electric shutter 23 may be a plurality of blade-shaped parts provided at the position of the smoking port 21, and the passage of the smoking port 21 may be switched by turning over the structure of each blade in the shutter.
如图4所示,电动百叶窗23可以通过电机驱动的方式,使多个叶片形部件都发生翻转。具体地,在本申请的部分实施例中,所述电动百叶窗23包括电机231、传动机构232以及叶片233;多个叶片233通过传动机构232连接电机231,电机231连接控制器6。其中,传动机构232的传动方式可以为链传动,叶片233的一端设有链轮,传动机构232包括链条,电机231的输出端也设有链轮,电机231上的链轮通过链条连接多个叶片233上的链轮,以在电机231转动时带动叶片233转动。As shown in FIG. 4, the electric louver 23 can be driven by a motor to turn over a plurality of blade-shaped components. Specifically, in some embodiments of the present application, the electric shutter 23 includes a motor 231, a transmission mechanism 232, and blades 233; a plurality of blades 233 are connected to the motor 231 through the transmission mechanism 232, and the motor 231 is connected to the controller 6. Among them, the transmission mode of the transmission mechanism 232 can be a chain transmission, one end of the blade 233 is provided with a sprocket, the transmission mechanism 232 includes a chain, and the output end of the motor 231 is also provided with a sprocket, and the sprocket on the motor 231 is connected to a plurality of through the chain The sprocket on the blade 233 drives the blade 233 to rotate when the motor 231 rotates.
实际应用中,当需要通过所述电动百叶窗23封堵吸烟口21时,可通过控制器6 发送一个启动信号,控制电机231转动预设角度或预设圈数,电机231上的链轮驱动链条,带动每个叶片233上的链轮转动,以使叶片233翻转,由多个叶片233组成阻挡屏障,遮挡住吸烟口21。为了便于对电机231的转动进行控制,所述电机231可以是伺服电机或步进电机。另外,传动机构232中还可以设置减速器等传动部件,以输出特定传动比,便于对电机231进行控制。In practical application, when the smoking opening 21 needs to be blocked by the electric shutter 23, a start signal can be sent through the controller 6 to control the motor 231 to rotate by a preset angle or a preset number of turns, and the chain wheel on the motor 231 drives the chain , Driving the sprocket on each blade 233 to rotate, so that the blade 233 is turned over, and a plurality of blades 233 form a blocking barrier to block the smoking port 21. In order to facilitate the control of the rotation of the motor 231, the motor 231 may be a servo motor or a stepper motor. In addition, the transmission mechanism 232 may also be provided with transmission components such as a speed reducer to output a specific transmission ratio to facilitate the control of the motor 231.
如图3所示,所述吹风管道5在电动百叶窗23的上方连通排烟管道2,吹风管道5从排烟管道2延伸到位于外壳1底部的吹风口51。吹风口51位于外壳1的底部位置,靠近锅具4的放置位置,从而使吹风口51流出的气流,能够直接作用在锅具4上,增加作用在锅具4上的空气流速,加快残留水分的蒸发速度。控制器6分别连接风机3以及电动百叶窗23,以控制电动百叶窗23封堵吸烟口21,并控制风机3反转,通过吹风管道5向锅具4输送气流。需要说明的是,本申请中所使用的控制器6是指能够实现信息判断并自动控制的处理器芯片,例如单片机,可编程逻辑控制器等。控制器6可以安装在外壳1的中部位置,与操控面板的位置相同,以便于实现电路连接以及使所述吸油烟机的整体结构更加紧凑。As shown in FIG. 3, the blower duct 5 communicates with the smoke exhaust duct 2 above the electric shutter 23, and the blower duct 5 extends from the smoke exhaust duct 2 to the blower opening 51 at the bottom of the housing 1. The air outlet 51 is located at the bottom of the housing 1, close to the placement position of the pot 4, so that the airflow from the air outlet 51 can directly act on the pot 4, increasing the air flow rate acting on the pot 4 and accelerating the residual moisture Evaporation rate. The controller 6 is connected to the fan 3 and the electric shutter 23 respectively to control the electric shutter 23 to block the smoking port 21, and controls the fan 3 to reverse, and sends the airflow to the pot 4 through the blowing duct 5. It should be noted that the controller 6 used in the present application refers to a processor chip that can realize information judgment and automatic control, such as a single-chip computer, a programmable logic controller, and the like. The controller 6 can be installed at a central position of the housing 1, which is the same as the position of the control panel, so as to realize circuit connection and make the overall structure of the range hood more compact.
实际应用中,在正常烹饪状态下,电动百叶窗23处于开启状态,风机3正转运行,锅具4中产生的油烟,被排烟管道2中产生的气流从吸烟口21吸入,经过排烟管道2至排烟口22,排出到室外,即进行正常吸油烟作业。而当使用者对锅具4进行清洗,并需要去除锅具4中残留的水分时,控制器6向风机3发送反转信号,控制风机3进行反向转动,使排烟管道2中产生向室内的气流。同时,控制器6还向电动百叶窗23发送关闭信号,控制电动百叶窗23中的电机231进行转动,从而使电动百叶窗23的叶片233发生翻转,关闭吸烟口21。此时,排烟管道2只与吹风管道5连通,因此排烟管道2中产生的向室内的气流会从吹风管道5流动至吹风口51。最终作用在锅具4上,使得锅具4所在区域的空气流动速度加快,即进行风干作业,加速锅具4上残留的水分蒸发。In practical applications, under normal cooking conditions, the electric shutters 23 are in the open state, the fan 3 is running forward, and the oil smoke generated in the pot 4 is sucked in from the smoking port 21 by the air flow generated in the smoke exhaust pipe 2 and passes through the smoke exhaust pipe 2 to the smoke exhaust port 22, discharged to the outdoor, that is, normal oil fume operation. When the user cleans the pot 4 and needs to remove the residual water in the pot 4, the controller 6 sends a reverse signal to the fan 3 to control the fan 3 to rotate in the reverse direction, so that the Indoor airflow. At the same time, the controller 6 also sends a closing signal to the electric shutter 23 to control the motor 231 in the electric shutter 23 to rotate, so that the blade 233 of the electric shutter 23 is turned over, and the smoking port 21 is closed. At this time, the smoke exhaust duct 2 is only in communication with the blowing duct 5, so the airflow generated in the smoke exhaust duct 2 toward the room will flow from the blow duct 5 to the blow port 51. Finally, it acts on the pot 4 to speed up the air flow in the area where the pot 4 is located, that is, to perform the air-drying operation and accelerate the evaporation of the remaining moisture on the pot 4.
本申请提供的技术方案中,风机3反转运行的时间可以根据锅具4的大小以及形状进行设置。例如,平底锅上水分残留的面积较大,蒸发速度也较快,因此风机3反转运行的时间可以设置的较短;而圆底锅水分多残留在锅底,因此需要风机3反转运行较长时间才可以将水分完全蒸发掉。In the technical solution provided by the present application, the time when the fan 3 runs in reverse can be set according to the size and shape of the pot 4. For example, the area of the remaining water on the pan is larger and the evaporation speed is faster, so the time for the fan 3 to run in reverse can be set shorter; while the water in the round pan remains mostly at the bottom of the pan, so the fan 3 is required to run in reverse It takes a long time to completely evaporate the water.
本申请提供的技术方案中,通过在吸油烟机中增加吹风管道5,并利用风机3反转运行向锅具4吹送气流,以加速锅具4中残留的水分蒸发。因此,在本申请提供的 技术方案中,以风干作业的方式防止锅具4生锈的方案,可以适用任何类型的锅具,不会改变使用者的烹饪习惯。另外,在正常烹饪过程中,吹风口51还可以与吸烟口21同时吸收油烟,增大油烟的吸收效率。In the technical solution provided by the present application, a blower duct 5 is added to the range hood, and the fan 3 is used to reverse the operation to blow airflow to the cookware 4 to accelerate the evaporation of the remaining moisture in the cookware 4. Therefore, in the technical solution provided by the present application, the solution for preventing the rusting of the pot 4 in the manner of air-drying operation can be applied to any type of pot without changing the user's cooking habits. In addition, during the normal cooking process, the air outlet 51 can also absorb oil fume at the same time as the smoking mouth 21, increasing the absorption efficiency of the oil fume.
由于在本申请提供的技术方案中,吹风管道5中向外输送的气体来源于排烟管道2,而在实际应用中,排烟管道2一般连通室外或者建筑物的烟道,而当建筑物采用共用烟道设计时,共用烟道中经常存在其它房间产生的油烟,油烟受向室内气流影响,很容易被吸收进排烟管道2,从而使吹风口51吹送的气体也包含有油烟,这将产生异味,影响室内空气质量。为了避免共用烟道中的油烟进入室内,在本申请的部分实施例中,吸油烟机还包括进气管道7,排烟口22的位置设有可封堵排烟口22的第一阀门24,进气管道7在第一阀门24与风机3之间位置,连通排烟管道2。进气管道7上设有可封堵进气管道7的第二阀门71;第一阀门24和第二阀门71连接控制器6。In the technical solution provided by the present application, the gas conveyed outward in the blower duct 5 comes from the smoke exhaust duct 2, and in practical applications, the smoke exhaust duct 2 is generally connected to the outdoor or the flue of the building. When the shared flue design is adopted, there are often oil fumes from other rooms in the shared flue. The oil fumes are easily absorbed into the exhaust duct 2 due to the air flow to the room, so that the gas blown by the blower 51 also contains oil fumes, which will It produces odor and affects indoor air quality. In order to prevent the oil fume in the common flue from entering the room, in some embodiments of the present application, the range hood further includes an air intake duct 7, and a first valve 24 that can block the smoke exhaust port 22 is provided at the position of the smoke exhaust port 22. The air intake duct 7 is located between the first valve 24 and the fan 3 and communicates with the smoke exhaust duct 2. The intake pipe 7 is provided with a second valve 71 which can block the intake pipe 7; the first valve 24 and the second valve 71 are connected to the controller 6.
所述进气管道7的一端连通排烟管道2,另一端通向室内环境,即设置在外壳1上。正常进行烹饪过程中,排烟管道2上的第一阀门24处于开启状态,使排烟管道2能够正常向外排出油烟,进气管道7上的第二阀门71处于关闭状态,以避免排烟管道2中的油烟进入室内环境。当需要所述吸油烟机向锅具4吹送气流时,控制器6向第一阀门24发送关闭指令,使第一阀门24关闭,阻隔排烟管道2与烟道。同时向第二阀门71发送开启指令,使第二阀门71开启,使排烟管道2与进气管道7之间连通。此时,风机3进行反转,排烟管道2中产生向室内的气流,气流来源于进气管道7,由于进气管道7连通室内环境,因此室内环境中的空气输送给进气管道7,即避免烟道中的油烟进入室内。One end of the air intake duct 7 communicates with the smoke exhaust duct 2 and the other end leads to the indoor environment, that is, it is installed on the housing 1. During the normal cooking process, the first valve 24 on the smoke exhaust pipe 2 is in an open state, so that the smoke exhaust pipe 2 can normally discharge oil smoke outward, and the second valve 71 on the intake pipe 7 is closed to avoid smoke exhaust The oil smoke in the pipe 2 enters the indoor environment. When the range hood is required to blow the airflow to the pot 4, the controller 6 sends a closing command to the first valve 24 to close the first valve 24 and block the smoke exhaust pipe 2 and the flue. At the same time, an opening command is sent to the second valve 71 to open the second valve 71, so that the smoke exhaust pipe 2 and the intake pipe 7 communicate. At this time, the fan 3 reverses, and the air flow to the room is generated in the smoke exhaust duct 2. The air flow originates from the air intake duct 7. Since the air intake duct 7 communicates with the indoor environment, the air in the indoor environment is sent to the air intake duct 7, That is to avoid the oil fumes in the flue entering the room.
