the oil smoke sensor 4 is electrically connected with the controller 3 and used for detecting the concentration of oil smoke;
the controller 3 is used for controlling the starting and stopping states of the cigarette machine main body 1 and the air purifying device 2 according to the oil smoke concentration.
In this embodiment, the purge air duct and the range hood air duct are not communicated with each other. The oil smoke suction duct is used for discharging oil smoke to the outside; of course, the oil smoke suction duct is internally provided with an oil smoke fan for enabling the air flow to flow from the smoke inlet to the smoke outlet, and the opening of the oil smoke suction function of the range hood main body 1 is usually realized by controlling the opening of the oil smoke fan. It then filters piece and purification fan to purify in the wind channel, and purification fan is used for making the air current certainly air intake 201 flow direction air outlet 202 filters the purification to filtering the piece then being used for flowing through the air that purifies the wind channel, and the air after the purification passes through air outlet 202 is arranged back to the kitchen indoor, usually through opening of control purification fan, controls opening of air purification device 2. Therefore, when the air purification device 2 and the smoke exhaust ventilator main body 1 work cooperatively, most of the oil smoke generated in the cooking process can be discharged to the outside through the oil smoke suction air duct, a small part of the oil smoke can escape to other spaces in a kitchen, and the small part of the oil smoke can be further removed through the purification air duct, so that the pollution of the oil smoke to the air environment and the damage to the health of a human body are further reduced.
In addition, in this embodiment, the range hood is further provided with a smoke sensor 4 and a controller 3, and the controller 3 can acquire the smoke concentration in the kitchen space through the smoke sensor 4 and control the start-stop states of the range hood main body 1 and the air purification device 2 according to the smoke concentration; it can be understood, the size of oil smoke concentration can represent the air quality in the kitchen space good or bad, so the accessible the size of oil smoke concentration judges the opening demand of cigarette machine main part 1 and/or air purification device 2 to when having the opening demand, control cigarette machine main part 1 and/or air purification device 2 and open automatically, promote range hood's intellectuality, and then can avoid opening cigarette machine main part 1 and/or air purification device 2 because of the user forgets, and the phenomenon that leads to the produced oil smoke of culinary art to spread appears in the kitchen space.
Optionally, the range hood main body 1 includes a decoration cover 11 and a smoke collecting cover 12 disposed below the decoration cover 11, and the air purifying device 2 is disposed in the decoration cover 11 to share a common appearance member, thereby simplifying the structure of the range hood. Of course, the decoration cover 11 is provided with a first avoiding opening 111 corresponding to the air inlet 201 and a second avoiding opening 112 corresponding to the air outlet 202.
However, the design is not limited thereto, and in other embodiments, referring to fig. 3, the air purifying device 2 may also be disposed outside the cigarette maker body 1, for example, but not limited to, being fixed on the front surface of the decoration cover 11. In still other embodiments, the air purifying device 2 may also be installed without being attached to the cigarette maker main body 1, that is, the air purifying device 2 may be movable relative to the cigarette maker main body 1, at this time, the air purifying device 2 may be connected to the cigarette maker main body 1 through a power supply line to be powered by the cigarette maker main body 1, or the air purifying device 2 may be provided with a plug-in device, and may be powered by an independent plug-in manner.
Alternatively, referring to figure 1, the controller 3 is fixedly mounted to the cigarette maker body 1; it will be appreciated that the cigarette maker body 1 is generally larger in volume and has more and more convenient locations and spaces for mounting the controller 3 than the air cleaning device 2. The controller 3 is in communication connection with a lampblack blower of the cigarette machine body 1 and a purification blower of the air purification device 2 usually in a wired manner so as to send a starting signal and a stopping signal to the cigarette machine body 1 and the air purification device 2; of course, the controller 3 may also be in communication connection with the smoke ventilator of the smoke machine main body 1 and the purification ventilator of the air purification device 2 in a wireless manner, and particularly, in the technical scheme that the air purification device 2 is movable relative to the smoke machine main body 1, the controller 3 is usually in wireless communication connection with the purification ventilator of the air purification device 2.
In addition, optionally, the range hood is further provided with a control switch 5 for a user to control the manual starting of the range hood main body 1 and/or the air purification device 2, so that the user can more flexibly control the starting and stopping states of the range hood main body 1 and/or the air purification device 2.
In one embodiment, the smoke sensor 4 is provided on the cigarette maker body 1. Since the controller 3 is usually arranged on the cigarette machine body 1, the smoke sensor 4 is also arranged on the cigarette machine body 1, and the electric connection between the smoke sensor and the controller 3 can be realized more conveniently. In addition, the cigarette maker body 1 is generally larger than the air cleaning device 2, with more and more suitable mounting positions for the smoke sensor 4.
Alternatively, referring to fig. 1, the smoke sensor 4 is provided on the front surface of the smoke collecting hood 12 of the range hood main body 1 such that the smoke sensor 4 is closest to the front of the range hood. In the cooking process, a user usually stands in front of the range hood, and the space in front of the range hood can be defined as a user breathing zone. Locate the front of collection petticoat pipe 12 with oil smoke sensor 4, be favorable to oil smoke sensor 4 to acquire the oil smoke concentration that leaks out from user's breathing zone to the realization is according to the oil smoke concentration control cigarette machine main part 1 of user's breathing zone and the state of opening of air purification device 2, and improves the air quality of user's breathing zone in time. In addition, the control panel of the range hood is usually arranged on the front surface of the smoke collecting hood 12, and the smoke sensor 4 is integrated on the control panel, so that the assembly process can be reduced.
However, the design is not limited to this, in other embodiments, the smoke sensor 4 may also be disposed on the side surface of the smoke collecting hood 12, so as to be beneficial to obtaining the concentration of the smoke leaked from the side of the smoke machine main body 1; particularly, when a cooker with double burners is arranged below the range hood, lampblack generated during cooking easily escapes from the side direction of the range hood main body 1, the lampblack sensor 4 is arranged on the side surface of the smoke collecting hood 12, so that the escaping diffusion of the cooking lampblack can be sensed more quickly, and the range hood main body 1 and/or the air purification device 2 are controlled to be opened to reduce the cooking lampblack.
In still other embodiments, the smoke sensor 4 may be disposed at the upper end of the decoration cover 11. It can be understood that cooking fumes tend to escape upwards and accumulate in the space above the kitchen, due to the action of the thermal plume of the cooking fumes; the upper end of the decoration cover 11 is closest to the upper space of the kitchen, the oil smoke sensor 4 is arranged at the upper end of the decoration cover 11, the oil smoke sensor 4 is favorable for acquiring the oil smoke concentration of the upper space of the kitchen, the oil smoke concentration can reflect the overall air quality of the kitchen more truly, and therefore the opening of the cigarette machine main body 1 and/or the air purification device 2 is favorably controlled according to the overall air quality of the kitchen.
In an embodiment, after the power line of the range hood is connected with the mains supply, if a user forgets to turn on the range hood main body 1 and the air purification device 2 during cooking, and the range hood main body 1 and the air purification device 2 are both in a shutdown state, the controller 3 judges the turn-on demand of the range hood main body 1 and/or the air purification device 2 according to the oil smoke concentration, so that the range hood main body 1 and/or the air purification device 2 are controlled to be automatically turned on when the turn-on demand exists.
For example, when the oil smoke concentration is not less than the first preset concentration and less than the second preset concentration, it may be determined that there is oil smoke in the kitchen that may slightly affect the user and the environment, or a small amount of oil smoke is generated during the cooking process, so that the controller 3 controls the air purification device 2 to be opened to perform internal circulation purification on the oil smoke by using the air purification device 2, it may be understood that the energy consumption required for opening the air purification device 2 is lower than that required for opening the cigarette maker main body 1, of course, the air volume of the purification fan of the air purification device 2 may be less than that of the oil smoke fan of the cigarette maker main body 1, and in the case that only opening the air purification device 2 can satisfy the requirement for improving the air quality, the energy consumption required for opening only the air purification device 2 is the lowest.
For another example, when the concentration of the lampblack is not less than the second preset concentration and less than the third preset concentration, it may be determined that a large amount of lampblack is generated in the cooking process, so that the controller 3 controls the range hood body 1 to be opened to discharge the lampblack outdoors by using the lampblack suction duct of the range hood body 1, and it can be understood that the lampblack fan of the range hood body 1 has a large air volume to discharge the large amount of lampblack outdoors. Of course, the values of the second preset concentration and the third preset concentration can be determined through experiments, and in the range, when the range hood main body 1 is independently opened, all the oil smoke can be basically discharged outdoors, or when the range hood main body 1 is independently opened, only a little oil smoke can escape from the range hood. Compared with the method that the cigarette machine main body 1 and the air purification device 2 are simultaneously opened, the energy consumption for only opening the cigarette machine main body 1 is lower.
For another example, when the oil smoke concentration is not less than the third preset concentration, it may be determined that a maximum amount of oil smoke is generated during the cooking process, at this time, if only the range hood body 1 is opened to discharge the oil smoke outside, there will still be a lot of oil smoke escaping upwards from the edge of the range hood, so that the controller 3 controls both the range hood body 1 and the air purification device 2 to be opened, so as to discharge a large amount of oil smoke outdoors by using the oil smoke suction duct of the range hood body 1 on one side, and suck and purify the oil smoke escaping upwards by using the purification duct of the air purification device 2 on the other side, thereby quickly removing the indoor oil smoke.
In an embodiment, if the user only starts the smoke exhaust machine main body 1 to exhaust smoke during cooking, and the air purification device 2 is in a stop state, at this time, because of the smoke exhaust action of the smoke exhaust machine main body 1, when only a small amount of or a large amount of smoke is generated during cooking, little smoke will escape from the smoke exhaust machine. However, when a great amount of oil smoke is generated during cooking, although most of the oil smoke is discharged to the outside by the range hood main body 1, a part of the oil smoke escapes upwards from the edge of the range hood, at this time, if the concentration of the oil smoke is still not less than the fourth preset concentration, it can be determined that the great amount of oil smoke is generated during cooking, so that the controller 3 controls the air purification device 2 to be also opened, the escaped oil smoke is sucked and purified through the air purification device 2, and the oil smoke is rapidly removed through the range hood main body 1 and the air purification device 2 together. It should be noted that, in this embodiment, the fourth preset concentration may be the same as or slightly different from the first preset concentration in the foregoing embodiment.
During cooking, edible oil and food undergo a series of chemical reactions such as oxidation, cracking and polymerization at high temperature, a large amount of organic smoke is evaporated, and partial decomposition products are emitted into air in the form of oil mist to form oil smoke. The oil fume includes both edible oil and its heating decomposition or cracking product and also includes the physical and chemical reaction product of protein, polymer compound and various seasoning matters in food, and is one kind of matter containing gas, liquid and solid. Generally, the Particulate Matter Emission (PME) composed of liquid and solid in the oil smoke emission is defined as PME, and the Volatile Organic Compounds emission (VOCs) is defined as VOCs, and the oil smoke is composed of the above two substances. Based on this, the soot concentration can be characterized by the particulate matter concentration and/or the odor concentration.
In one embodiment, the soot sensor 4 includes only a particulate matter sensor to determine the quality of air in the kitchen by detecting the concentration of particulate matter in the air. It can be understood that in the present embodiment, in the process of controlling the start-stop state of the range hood main body 1 and the air purification device 2 according to the soot concentration, the determination control is performed according to the particulate matter concentration, and accordingly, the first to fourth preset concentrations in the foregoing embodiment correspond to the first to fourth preset particulate matter concentrations, respectively. For example: when the lampblack sensor 4 only comprises a particulate matter sensor, the first preset particulate matter concentration is 75.0 mu g/m3The second preset particle concentration is 150 mu g/m3The third preset particulate matter concentration is 300 mu g/m3That is, if the user forgets to turn on the cigarette maker body 1 and the air cleaning device 2 during cooking and the cigarette maker body 1 and the air cleaning device 2 are both in a shutdown state, when the particle sensor detects that the concentration of the particles is not less than 75.0 μ g/m3And less than 150. mu.g/m3The controller 3 only controls the air purification device 2 to be started; when the particle sensor detects that the measured particle concentration is not less than 150.0 mu g/m3And less than 300. mu.g/m3The controller 3 only controls the cigarette machine main body 1 to be opened; when the particle sensor detects that the measured particle concentration is not less than 300 mu g/m3And the controller 3 controls the cigarette machine main body 1 and the air purification device 2 to be opened.
However, the design is not limited thereto, and in other embodiments, the soot sensor 4 may also only include an odor sensor to determine the air quality in the kitchen by detecting the concentration of the odor in the air. It can be understood that in the present embodiment, in the process of controlling the on-off states of the cigarette maker main body 1 and the air cleaning device 2 according to the smoke concentration, the judgment and control are performed according to the odor concentration, and accordingly, the first to fourth preset concentrations in the foregoing embodiment correspond to the first to fourth preset odor concentrations, respectively. For example: when the lampblack sensor 4 only comprises an odor sensor, the first preset odor concentration is 0.6mg/m3The second preset odor concentration is 1.0mg/m3The third preset odor concentration is 3.0mg/m3That is, when the user forgets to turn on the cigarette maker body 1 and the air cleaning device 2 during cooking and both the cigarette maker body 1 and the air cleaning device 2 are in a stopped state, the odor sensor detects that the detected odor concentration is not less than 0.6mg/m3And less than 1.0mg/m3The controller 3 only controls the air purification device 2 to be started; when the odor sensor detects the detected odor concentration not less than 1.0mg/m3And less than 3.0mg/m3The controller 3 only controls the cigarette machine main body 1 to be opened; when the odor sensor detects the detected odor concentration not less than 3.0mg/m3The controller 3 controls the main body of the cigarette machine1 and the air cleaning device 2 are both turned on.
In yet other embodiments, the soot sensor 4 may also include a particle sensor and an odor sensor to detect the concentration of particles and odor in the air to determine the quality of the air in the kitchen. It can be understood that in the present embodiment, in the process of controlling the start-stop states of the cigarette making machine main body 1 and the air purification device 2 according to the smoke concentration, the judgment control is performed according to the particulate matter concentration and the odor concentration, and accordingly, the first preset concentration in the foregoing embodiment includes a first preset particulate matter concentration and a first preset odor concentration, the second preset concentration includes a second preset particulate matter concentration and a second preset odor concentration, the third preset concentration includes a third preset particulate matter concentration and a third preset odor concentration, and the fourth preset concentration includes a fourth preset particulate matter concentration and a fourth preset odor concentration; it is understood that the first to fourth predetermined concentrations of particulate matter are all within the predetermined concentration of particulate matter, and the first to fourth predetermined concentrations of odor are all within the predetermined concentration of odor. It should be noted that, in the present embodiment, in order to make the control response of the controller 3 quicker, as long as any one of the comparison result between the particulate matter concentration and the preset particulate matter concentration and the comparison result between the odor concentration and the preset odor concentration is determined to satisfy the preset condition, the controller 3 controls the cigarette maker main body 1 and/or the air cleaning device 2 corresponding to the preset condition to be turned on. For example: "it is determined that the oil smoke concentration is not less than the fourth preset concentration, and the controller 3 controls the air purification device 2 to be turned on" specifically, when any one of the particulate matter concentration is not less than the fourth preset particulate matter concentration and the odor concentration is not less than the fourth preset odor concentration is determined, the controller 3 controls the air purification device 2 to be turned on ".
