a controller 3 electrically connected to the pressure sensor 24;
the controller 3 is used for regulating and controlling the operation speed of the purification fan 23 of the air purification device 2 according to the pressure in the purification air duct.
In this embodiment, the range hood main body 1 is provided with a smoke exhaust duct, and the purification duct of the air purification device 2 is not communicated with the smoke exhaust duct. The smoke inlet of the oil smoke suction duct is communicated with the indoor and is usually suspended above a kitchen range so as to suck oil smoke into the oil smoke suction duct; the smoke outlet of the oil smoke suction duct is communicated with the outside so as to discharge oil smoke to the outside; of course, the oil fume suction duct is internally provided with an oil fume fan for enabling the airflow to flow from the fume inlet to the fume outlet. It can be understood that the range hood main body 1 has the functions of the traditional range hood.
In addition, in this embodiment, the range hood is further provided with a controller 3, optionally, the range hood main body 1 and the air purification device 2 are connected to the same controller 3, that is, the range hood controls the range hood main body 1 and the air purification device 2 through the same controller 3, for example, the range hood controls the range hood main body 1 and the air purification device 2 through the same controller 3 to perform a smoking operation, and preferably, the controller 3 is generally disposed on the range hood main body 1. It should be noted that the cigarette maker main body 1 is generally larger in volume than the air cleaning device 2, so that there is more space and space for the controller 3 to be installed.
However, the design is not limited thereto, and in other embodiments, the range hood may also be provided with two different controllers 3 to respectively control the range hood body 1 and the air purification device 2.
In addition, in this embodiment, this range hood still is equipped with control switch 4, optionally, cigarette machine main part 1 and air purification device 2 share a control switch 4, so, when opening cigarette machine main part 1 through control switch 4 and carry out work, can open air purification device 2 simultaneously and carry out work automatically, promptly, can realize the collaborative work that a key opened cigarette machine main part 1 and air purification device 2. The control switch 4 is usually electrically connected to the controller 3 to realize the on/off control. When one control switch 4 is shared, the control switch 4 is normally provided on the cigarette maker main body 1.
However, the design is not limited thereto, in other embodiments, the cigarette maker main body 1 and the air purification device 2 may also use different control switches 4, respectively, to implement independent on/off control of the cigarette maker main body 1 and the air purification device 2, so that a user may use respective functions of the cigarette maker main body 1 and the air purification device 2 more flexibly. When different control switches 4 are respectively used, the two control switches 4 can be arranged on the cigarette machine main body 1; of course, the two control switches 4 can also be correspondingly arranged on the cigarette machine main body 1 and the air cleaning device 2 respectively.
In addition, in this embodiment, this range hood still is equipped with first oil smoke sensor and second oil smoke sensor, and wherein, first oil smoke sensor locates on air purification device, and second oil smoke sensor locates on the cigarette machine main part, first oil smoke sensor and second oil smoke sensor all are used for detecting the oil smoke concentration, and specifically, controller 3 acquires the oil smoke concentration of the air intake that the kitchen space corresponds through first oil smoke sensor to confirm air purification device's operational mode according to the oil smoke concentration, and controller 3 acquires the oil smoke concentration of the air intake that the kitchen space corresponds through the second oil smoke sensor, and confirms the operational mode of cigarette machine main part according to the oil smoke concentration.
Optionally, a first oil smoke sensor is disposed at the air inlet 201 of the air purification device 2, so that the first oil smoke sensor is used for monitoring the oil smoke concentration of the air purification device 2 before filtering, and further facilitating sensing of escaping diffusion of cooking oil smoke by the first oil smoke sensor, and determining whether a filtering piece of the air purification device 2 is invalid or not.
In one embodiment, the first soot sensor is provided in the body 1 of the cigarette maker. Since the controller 3 is usually disposed on the cigarette machine body 1, the first smoke sensor is also disposed on the cigarette machine body 1, so that the first smoke sensor can be electrically connected to the controller 3 more conveniently. In addition, the range hood body 1 is generally larger than the air cleaning device 2, with more and more suitable mounting locations for the first smoke sensor.
Optionally, the air purification apparatus 2 further includes a wind guiding blade, which is rotatably disposed at the air outlet 202, so as to adjust the air outlet direction of the air outlet 202 by rotating the wind guiding blade, and the air outlet direction of the air outlet 202 is continuously adjustable. However, the design is not limited to this, in other embodiments, a plurality of air guiding frames with fixed air guiding blades may be installed on the air outlet 202, the air guiding frames are configured, the inclination angles of the air guiding blades of different air guiding frames are different, and the air outlet direction of the air outlet 202 can be changed by replacing different air guiding frames.
Optionally, the air guide vane extends along the transverse direction, and in the rotating process of the air guide vane, an included angle between the air guide vane and the horizontal plane ranges from-90 degrees to 90 degrees; it can be understood that when the included angle between the wind guide blade and the horizontal plane is less than zero, the wind guide blade is inclined downwards for guiding wind, and when the included angle between the wind guide blade and the horizontal plane is greater than or equal to zero, the wind guide blade is inclined upwards for guiding wind; in this embodiment, the wind guiding direction of the wind guiding blades can be continuously adjustable from approximately vertical downward to approximately vertical upward.
Further optionally, an included angle between the air guide blade and the horizontal plane ranges from-45 degrees to 45 degrees, and under the included angle range, the air guide direction of the air guide blade can ensure a larger ventilation rate of the air outlet 202 while considering a user breathing area and an oil smoke accumulation area in front of and above the range hood; it can be understood that the more the included angle between the wind guide blade and the horizontal plane is close to-90 degrees or 90 degrees, the larger the wind resistance generated by the wind guide blade is.
In addition, in other embodiments, the angle between the wind guide blade and the horizontal plane may range from 30 ° to 75 °. It can be understood that, in this rotation range, the wind guiding blades extend obliquely upward, so that the wind blown out from the wind outlet 202 is mainly delivered in an obliquely upward direction, and thus has a large upward wind outlet component, and the upward wind outlet component can push the oil smoke in the upper half of the kitchen space to flow downward, so as to be sucked and purified by the wind inlet 201, and thus the oil smoke in the upper half of the kitchen space can be taken into the air circulation purification (as shown in fig. 5), and the oil smoke in the kitchen can be further reduced.
Furthermore, during the cooking process, a series of chemical reactions such as oxidation, cracking and polymerization occur between the edible oil and the food at high temperature, a large amount of organic fumes are evaporated, and part of decomposed products are emitted into the air in the form of oil mist to form oil fumes.
