本发明涉及厨房电器技术领域，特别涉及一种吸油烟机。The invention relates to the technical field of kitchen appliances, in particular to a range hood.
背景技术Background technique
随着生活水平的提高，吸油烟机已逐渐成为众多用户不可或缺的厨房电器，吸油烟机吸排油烟的能力是其最基本的核心性能。目前大多用户家庭中使用的灶具都是双灶，具有左右两个炉头，炒菜的锅具处于吸油烟机的两侧。传统的吸油烟机大多只有一个进风口，很难具有良好的吸排油烟效果。为了提升吸排油烟能力，现有技术通常有两种解决方案，一种是，通过加大风机的转速来增大进风量，这种方案会产生较大的噪音；另一种是，通过设计具有两个进风口的吸油烟机，且每一个进风口均对应设置有一个风机，这种方案不仅增加了生产成本，并且两个风机同时工作时，两个风机之间的空气会同时向两个风机流动，而使两风机之间的空气流动紊乱，在一定程度上增加了吸油烟机的噪音。因此，现有的吸油烟机很难兼顾较好的吸油烟效果及较小的噪音。With the improvement of living standards, range hoods have gradually become an indispensable kitchen appliance for many users. The ability to absorb and exhaust range hood is its most basic core performance. At present, the stoves used in most households are double stoves, with two burners on the left and right, and the cooking utensils are located on both sides of the range hood. Most of the traditional range hoods only have one air inlet, and it is difficult to have a good effect of sucking and exhausting the range hood. In order to improve the oil fume suction and exhaust capability, there are usually two solutions in the prior art. One is to increase the air intake by increasing the speed of the fan, which will generate greater noise; the other is to design a For a range hood with two air inlets, and each air inlet is equipped with a corresponding fan, this solution not only increases the production cost, but also when the two fans work at the same time, the air between the two fans will flow to the two fans at the same time. The flow of the fan makes the air flow between the two fans turbulent, which increases the noise of the range hood to a certain extent. Therefore, it is difficult for the existing range hood to take into account better range hood effect and less noise.

在本发明实施例中，如图1至图3所示，该吸油烟机100包括壳体10、风机组件20、导流板组件及多个冷凝板50。其中，壳体10具有一进烟口101，及与进烟口101连通的排烟通道；风机组件20设于排烟通道；导流板组件包括盖设于进烟口101的导流板30，导流板30的背离排烟通道的一面分隔设置有多个集烟腔31，任一集烟腔31的内壁面设有进风口32；多个冷凝板50一一对应地盖设于多个集烟腔31的进烟侧，且任一冷凝板50与对应的集烟腔31内的进风口32之间形成有进烟间隙。In the embodiment of the present invention, as shown in FIGS. 1 to 3 , the range hood 100 includes a casing 10 , a fan assembly 20 , a deflector assembly and a plurality of condensation plates 50 . Wherein, the housing 10 has a smoke inlet 101, and a smoke exhaust passage communicated with the smoke inlet 101; the fan assembly 20 is arranged in the smoke exhaust passage; the deflector assembly includes a deflector 30 covering the smoke inlet 101 , the side of the deflector 30 away from the smoke exhaust channel is separately provided with a plurality of smoke collection chambers 31, and the inner wall surface of any smoke collection chamber 31 is provided with an air inlet 32; The smoke inlet side of each smoke collecting chamber 31, and a smoke inlet gap is formed between any condensing plate 50 and the air inlet 32 in the corresponding smoke collecting chamber 31.
在本实施例中，壳体10用以形成吸油烟机100的整体外观，风机组件20设于壳体10的排烟通道内以在进烟口101处形成负压，而将油烟气流吸入排烟通道，具体地，风机组件20可包括蜗轮、风轮及电机等。导流板组件设于进烟口101处用以对烟气进行导流，使得烟气能够汇聚至集烟腔31内，并自进风口32进入排烟通道。导流板30上的集烟腔31的个数及分布可根据实际使用的灶具进行设置，例如，家庭中使用的灶具一般为左右双灶头，相应地，导流板30可对应左右两个灶头分别设置两个集烟腔31，当然，在一些特殊应用场合，会存在更多灶头的灶具，集烟腔31的数量可根据灶头的实际数量进行调整。每一集烟腔31的进烟侧均设置有一冷凝板50，其中，冷凝板50既可以安装于壳体10上，也可以安装于导流板30上，只要能够与集烟腔31内的进风口32之间可形成进烟间隙即可。以下主要以双集烟腔31配置双冷凝板50的吸油烟机100进行说明。In this embodiment, the housing 10 is used to form the overall appearance of the range hood 100, and the fan assembly 20 is arranged in the smoke exhaust passage of the housing 10 to form a negative pressure at the smoke inlet 101, so as to suck the oil fume into the exhaust air. The smoke channel, specifically, the fan assembly 20 may include a worm gear, a wind wheel, a motor, and the like. The deflector assembly is arranged at the smoke inlet 101 to guide the smoke, so that the smoke can gather into the smoke collection chamber 31 and enter the smoke exhaust channel from the air inlet 32 . The number and distribution of the smoke collecting cavities 31 on the deflector 30 can be set according to the actual cooker. For example, the cooker used in the family is generally a left and right double cooker. Correspondingly, the deflector 30 can correspond to the left and right two cookers. Two smoke collecting cavities 31 are provided respectively. Of course, in some special applications, there will be cookers with more burners, and the number of smoke collecting cavities 31 can be adjusted according to the actual number of burners. The smoke inlet side of each smoke collecting chamber 31 is provided with a condensing plate 50, wherein the condensing plate 50 can be installed on the housing 10 or on the deflector 30, as long as it can be connected with the inside of the smoke collecting chamber 31. It is sufficient to form a smoke inlet gap between the air inlets 32 . In the following, the range hood 100 with double smoke collecting chambers 31 and double condenser plates 50 is mainly used for illustration.
具体地，风机组件20工作时，会使得各集烟腔31内均形成负压区域，以提升对烟气的聚拢作用。并且，各冷凝板50与对应的集烟腔31内的进风口32之间形成进烟间隙，也即每一冷凝板50的四周区域均可与对应集烟腔31之间形成进烟通道，从而实现多面进烟，极大地提升了吸油烟效率。同时，通过设置多个冷凝板50，使得每一冷凝板50的尺寸相对较小，从而便于冷凝板50的拆装及清洗。例如，可将小尺寸的冷凝板50直接放入洗碗机等专业清洗设备中清洗，方便快捷，清洁更为彻底，能够很好的提升用户体验。Specifically, when the fan assembly 20 is working, a negative pressure area is formed in each smoke collecting chamber 31 to enhance the gathering effect on the smoke. Moreover, a smoke inlet gap is formed between each condensing plate 50 and the air inlet 32 in the corresponding smoke collecting chamber 31, that is, the surrounding area of each condensing plate 50 can form a smoke inlet channel with the corresponding smoke collecting chamber 31, In this way, smoke can be introduced from multiple sides, which greatly improves the efficiency of oil suction. At the same time, by arranging a plurality of condensation plates 50 , the size of each condensation plate 50 is relatively small, thereby facilitating disassembly and cleaning of the condensation plates 50 . For example, the small-sized condensation plate 50 can be directly put into professional cleaning equipment such as a dishwasher for cleaning, which is convenient and quick, and the cleaning is more thorough, which can greatly improve user experience.
本发明吸油烟机100通过在壳体10的排烟通道内设置单个的风机组件20，并且在导流板30上分隔设置有多个集烟腔31，且每一集烟腔31的进烟侧均设置一个冷凝板50，该冷凝板50与对应集烟腔31内的进风口32之间形成进烟间隙。通过采用单风机组件20匹配多集烟腔31及多冷凝板50的进气布局，在不增大集烟腔31尺寸及风机转速的前提下，能够有效增大导流板30上的负压区域，并实现多面进烟的效果，从而能够很好地兼顾较优的吸油烟效果与较低的噪音，以提升用户体验。此外，通过采用多个小尺寸的冷凝板50配合以替代传统的整块大尺寸冷凝板50的方案，不仅能够有效提升进烟面积，还能够有效提升冷凝板50的拆装与清洗便利性。The range hood 100 of the present invention is provided with a single fan assembly 20 in the smoke exhaust passage of the casing 10, and a plurality of smoke collecting chambers 31 are separately arranged on the deflector 30, and the smoke inlet of each smoke collecting chamber 31 A condensing plate 50 is arranged on each side, and a smoke inlet gap is formed between the condensing plate 50 and the air inlet 32 in the corresponding smoke collecting chamber 31 .

Specifically, the condensing plate 50 can be movably installed on the casing 10 or the deflector 30. When the smoke generated by the cooker is relatively large, the smoke between the condensing plate 50 and the air inlet 32 in the smoke collecting chamber 31 The gap is correspondingly increased for optimum oil fume extraction. The adjustment range of the condensation plate 50 can be set according to actual needs. For example, when the range hood 100 is turned off, the condensation plate 50 can be adjusted to seamlessly connect with the smoke collection cavity 31 so that the smoke intake gap is zero. The adjustment method of the condensation plate 50 can be realized by the user's self-adjustment, or the automatic adjustment of the range hood 100 .
