Detailed Description
To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are illustrated in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Referring to fig. 1, a method for controlling the operation of a range hood includes steps S200, S300, and S400.
And step S200, acquiring ozone concentration data in the environment of the range hood.
Specifically, the range hood can acquire ozone concentration data in the environment where the range hood is located in real time for analysis in the operation process, so that the exhaust control operation is realized according to the ozone concentration. The ozone concentration data is not acquired in a unique manner, and in one embodiment, the range hood may be provided with an ozone concentration detector, and the ozone concentration detector is connected with the controller. The ozone concentration detector is used for collecting ozone concentration data in real time in the starting and running process of the range hood and sending the collected ozone concentration data to the controller for analysis.
It will be appreciated that the particular type of ozone concentration detector is not exclusive as long as it is capable of detecting ozone concentration data, and in one embodiment, for example, it may be implemented directly with an ozone concentration sensor.
It should be noted that the installation position of the ozone concentration detector in the range hood is not unique, and in one embodiment, the ozone concentration detector can be separately installed at the air inlet or the air outlet of the range hood, and the ozone concentration detection operation is performed in real time during the starting operation of the range hood.
Further, in one embodiment, the range hood is provided with an ionization purification device, that is, a device which uses a generator electrode wire to form an ionization region through high-voltage static electricity to generate high-concentration charged ions, when the absorbed oil smoke passes through the ionization purification device, the charged oil smoke particles are rapidly charged, and when reaching a collector, the charged oil smoke particles are adsorbed on a low-voltage electrode plate under the coulomb force, so that the oil smoke is purified. The operation intensity of ionization purifier can be according to how much and different of oil smoke in the in-service use scene, and when the oil smoke is less, ionization purifier's operation gear is lower, only has the production of a small amount of ozone this moment to can not cause too much harm to the human body, only need through inhale arrange the subassembly through conventional operation discharge can. When the oil smoke is more, the operation gear of the ionization purification device is higher, a large amount of ozone is generated at the moment, the harm to the human health can be caused, and other adjustments are needed to be made on the operation of the suction and exhaust assembly at the moment. This embodiment is through with ozone concentration detector and ionization purifier integrated design, and ionization purifier is followed in ozone concentration detector's installation to can effectively reduce spare part. Because in the in-service use process, ozone is generally because ionization purifier produces to the ionization operation of oil smoke, with ozone concentration detector and ionization purifier integrated design in this embodiment, can also effectively guarantee the detection accuracy when ozone concentration detects, improve range hood operation control method's control reliability.
And step S300, comparing and analyzing the ozone concentration data with a preset ozone concentration threshold value.
Specifically, the controller stores preset ozone concentration data, and after the controller receives the ozone concentration data collected and sent by the ozone concentration detector, the controller compares and analyzes the ozone concentration data with a preset ozone concentration threshold value, and finally performs different operation controls according to a comparison and analysis result so as to avoid the influence of overhigh ozone concentration on the body health of a user.
It can be understood that the setting of the preset ozone concentration threshold is not unique, and in the actual use process, only one preset ozone concentration threshold can be set, and when the ozone concentration data is greater than the preset ozone concentration threshold and the ozone concentration data is less than the preset ozone concentration threshold, different controls can be performed. In other embodiments, a plurality of different preset ozone concentration thresholds may be set, and when the ozone concentration data is between the different preset ozone concentration thresholds, different operation controls may be performed.
And S400, when the ozone concentration data is greater than a preset ozone concentration threshold value, controlling a suction and exhaust assembly of the range hood to enhance gear operation.
Specifically, when the controller carries out comparative analysis according to ozone concentration data and predetermineeing ozone concentration threshold value, if the ozone concentration data appears and is greater than predetermineeing ozone concentration threshold value scope, it is higher to indicate ozone concentration under the current environment promptly, in order to guarantee that the user is healthy, will need carry out strong exhaust to the current environment and handle, also increases the operation gear of suction and exhaust subassembly, will contain the gas of ozone and arrange the external environment to fast.
The suction and exhaust assembly is a device for discharging oil smoke, and the specific type of the suction and exhaust assembly is not unique, and in one embodiment, the suction and exhaust assembly can comprise a volute, a motor and a centrifugal fan blade, wherein the motor and the centrifugal fan blade are arranged inside the volute, the centrifugal fan blade is connected with the motor, and in the actual operation process, the motor rotates to drive the centrifugal fan blade to rotate, so that gas containing oil smoke is exhausted. Correspondingly, the gear adjustment of the suction assembly is performed, that is, the rotating speed of the motor in the suction assembly is adjusted, and the corresponding rotating speed of the motor is increased under the condition of higher gear.
Referring to fig. 2, in an embodiment, before the step S200, the method further includes a step S100.
And S100, when a starting-up instruction is received, controlling an ionization purification device of the range hood to start and operate, and controlling a suction and exhaust assembly of the range hood to start and operate at a preset gear.
Specifically, the starting instruction is a starting instruction given to the range hood when a user has a demand for using the range hood, and under the control of the instruction, the ionization purification device and the suction and exhaust assembly in the range hood can be started to operate, so that an oil fume suction function is realized, and a good cooking environment is provided for the user. In this embodiment, the suction and exhaust assembly operates at a certain gear after receiving the power-on command. It can be understood that, in other embodiments, it may also be that when a start-up instruction is received, the ionization purification device is started to operate, and after the suction and exhaust assembly is further issued a gear selection instruction by a user, the operation is started at a corresponding gear, as long as it is ensured that the operation of collecting ozone concentration data is performed in a state where the ionization purification device is started to operate, because only on the basis of the start-up operation of the ionization purification device, a certain amount of ozone is generated by ionization of the oil smoke.
Referring to fig. 3, in one embodiment, step S400 includes step S410 and step S420.
Step S410, when the ozone concentration data is larger than a preset ozone concentration threshold value, detecting whether a suction and exhaust assembly of the range hood runs at a preset super-strong gear; step S420, when the suction and exhaust assembly does not operate at the preset super-strong gear, adjusting the operating gear of the suction and exhaust assembly to the preset super-strong gear.
Specifically, the preset super-strong gear is a gear which enables the operation efficiency of the suction and exhaust assembly to be far greater than that of the suction and exhaust assembly in the ordinary operation state of the range hood. In one embodiment, the preset super-strong gear may be set to a highest gear that the range hood can reach, that is, a maximum rotation speed corresponding to a motor in the suction and exhaust assembly, and under the preset super-strong gear, the operation efficiency of the suction and exhaust assembly is highest, so that the oil smoke, ozone and other gases can be exhausted to an external environment at a fastest speed.
In this embodiment, when the gear of individual suction and exhaust subassembly strengthened the control, ozone concentration or data under the too big condition, suction and exhaust subassembly only has a kind of operation gear, also predetermines super strong gear promptly. The controller directly carries out comparative analysis with a preset ozone concentration threshold value after obtaining the ozone concentration data, if the ozone concentration data is greater than the preset ozone concentration threshold value, it indicates that the range hood is in the environment ozone too much, and the controller will detect the current operation gear of the suction and exhaust assembly at this moment. If the suction and exhaust assembly does not operate at the preset super-strong gear (namely, the suction and exhaust assembly is lower than the preset super-strong gear), the operating gear of the suction and exhaust assembly is increased to the preset super-strong gear.
Further, referring to fig. 3, in an embodiment, after the step S410, the method further includes a step S430. And step S430, when the suction and exhaust assembly runs at the preset super-strong gear, maintaining the running gear of the suction and exhaust assembly unchanged.
Specifically, in this embodiment, when the controller detected the current operation gear of suction and discharge subassembly, still can appear current suction and discharge subassembly and already in order to predetermine the condition of superstrong gear operation, then only need maintain suction and discharge subassembly's running condition unchangeable this moment, can in time discharge ozone.
Referring to fig. 4, in one embodiment, step S400 includes step S440 and step S450.
Step S440, when the ozone concentration data is greater than a preset ozone concentration threshold value, detecting whether a suction and exhaust assembly of the range hood runs at a preset super-strong gear; and S450, when the suction and exhaust assembly does not operate at the preset super-strong gear, controlling the suction and exhaust assembly to increase the corresponding gear to operate according to ozone concentration data.
Specifically, this embodiment is different from the above-mentioned embodiment, and the suction and exhaust assembly in the above-mentioned embodiment only has one gear that carries out emission control to ozone, also predetermines super strong gear, directly carries out ozone emission with predetermineeing super strong gear when ozone is too high. In this embodiment, the suction and exhaust assembly has a plurality of gears for controlling ozone emission, and when the ozone concentration data is in different ranges, the corresponding operating gears of the suction and exhaust assembly are different, specifically, the gear is increased before the ozone concentration data is detected to be too high, and the specific increase amount is determined by the actual ozone concentration data. Similarly, when the suction assembly operates at the preset super-strong gear, the operation gear of the suction assembly is maintained to be unchanged.
In one embodiment, the step of controlling the suction and exhaust assembly to increase the operation of the corresponding gear according to the ozone concentration data comprises the following steps: when the ozone concentration data is greater than a first preset ozone concentration threshold and less than or equal to a second preset ozone concentration threshold, controlling the operation gear of the suction and exhaust assembly to increase by one gear; when the ozone concentration data is greater than a second preset ozone concentration threshold and less than or equal to a third preset ozone concentration threshold, controlling the operation gear of the suction and exhaust assembly to increase by two gears; when the ozone concentration data is greater than a third preset ozone concentration threshold value, the suction and discharge assembly is controlled to operate in a preset super-strong gear.
Specifically, the first preset ozone concentration threshold may be the same as the preset ozone concentration threshold, or may be slightly larger than the preset ozone concentration threshold. In this embodiment, the operation gear when carrying out ozone emission with inhaling the row of subassembly divide into three kinds of circumstances, and one is when ozone concentration data is greater than first predetermined ozone concentration threshold value and is less than or equal to the second predetermined ozone concentration threshold value, and ozone concentration data is not very high this moment, in order to guarantee that the user is healthy, only need suitably increase one shelves with inhaling the operation gear of arranging the subassembly, can be with the ozone discharge of production. And secondly, when the ozone concentration data is greater than a second preset ozone concentration threshold and less than or equal to a third preset ozone concentration threshold, the ozone concentration data is higher, if a first gear is added on the basis of the current operating gear, the ozone emission is slower, and the possibility of influencing the body health of a user still exists, so that at the moment, the suction and exhaust assembly is directly controlled to increase two operating gears for carrying out ozone emission control. And thirdly, when the ozone concentration data is greater than a third preset ozone concentration threshold value, the ozone concentration data is very high, and at the moment, the ozone is directly discharged by presetting a super-strong gear.
Particularly, if the current operation gear is lower than the preset super-strong operation gear by one gear, when the ozone concentration data is detected to be greater than a first preset ozone concentration threshold and less than or equal to a second preset ozone concentration threshold, increasing the one gear is that the operation gear of the suction and exhaust assembly is adjusted to be the preset super-strong gear. And if ozone concentration data is detected to be greater than the second preset ozone concentration threshold value and less than or equal to the third preset ozone concentration threshold value, the increase of two gears cannot be carried out, and at the moment, the operation gear of the suction and exhaust assembly is adjusted to be the preset super-strong gear.
It can be understood that in other embodiments, can also be with ozone concentration data divide into different grades, correspond at different grades and carry out different suction and exhaust subassembly gear reinforcing control, only need guarantee suction and exhaust subassembly when ozone concentration data is lower with lower operation gear operation, and along with the increase of ozone concentration data, the operation gear of suction and exhaust subassembly also increases thereupon, and in time can with ozone discharge atmospheric environment up to reaching and predetermineeing super strong gear.
In one embodiment, when the ozone concentration data is greater than the preset ozone concentration threshold, the method further comprises the steps of: and controlling an auxiliary heating device of the range hood to start and operate so as to reduce ozone into oxygen.
Specifically, in this embodiment, range hood still is provided with and assists the heat facility, when the controller detects range hood and locates in the environment ozone concentration too high, through assisting the heating of heat facility, can make the ozone reduction through assisting the heat facility for oxygen, and it is outdoor to discharge under the effect of suction assembly, even there is a small amount of effluvium to the kitchen environment, can not cause the influence to the health. Through this scheme, still can carry out reduction to ozone, avoid a large amount of ozone to discharge and cause environmental pollution in the atmospheric environment, further improve range hood's operational reliability.
It will be appreciated that the location of the auxiliary heating device is not exclusive and in one embodiment the auxiliary heating device may be located in the ionization and purification unit of the range hood. Because ozone is produced when ionization purifier carries out the static deoiling, this embodiment will assist heat facility and ionization purifier integrated setting, can make the ozone that ionization purifier produced directly flow through and assist the heat facility and heat the reduction for oxygen, effectively improves the conversion rate of ozone. In other embodiments, the auxiliary heating device may be separately disposed at an air outlet of the fume collecting hood of the range hood, as long as the ozone reduction operation can be performed.
Referring to fig. 5, in an embodiment, after step S400, the method further includes step S500.
And S500, when the ozone concentration data is detected to be smaller than a preset ozone concentration threshold value, controlling a suction and exhaust assembly of the range hood to recover the gear operation before enhancement.
Specifically, in the running process of the range hood, the controller obtains ozone concentration data in real time, compares and analyzes the obtained ozone concentration data with a preset ozone concentration threshold, and in the ozone discharging process, if the ozone concentration data is detected to be lower than the preset ozone concentration threshold, the ozone generation is reduced or the ozone is completely discharged, and at the moment, the range hood does not need to run at a higher gear, and the previous gear is directly recovered, so that the loss of electric energy is avoided.
According to the operation control method of the range hood, in the operation process of the range hood, ozone concentration data in the environment where the range hood is located can be obtained for analysis, and under the condition that the ozone concentration is high, the range hood correspondingly controls the range hood oil fume suction and exhaust assembly to enhance gear operation, so that the range hood performs oil fume exhaust operation at a high gear. Through above-mentioned scheme, can be fast when ozone concentration is too high with ozone and oil smoke synchronous discharge, avoid ozone concentration too high to influence that the user is healthy to purification reliability when effectively improving the kitchen oil smoke and purifying.

The start control module 100 is used for controlling the ionization purification device of the range hood to start and operate and controlling the suction and exhaust assembly of the range hood to start and operate at a preset gear when receiving a start instruction.
In one embodiment, the gear adjusting module 400 is further configured to detect whether the suction and exhaust assembly of the range hood operates in a preset super-strong gear when the ozone concentration data is greater than a preset ozone concentration threshold; when the suction and exhaust assembly does not operate at the preset super-strong gear, adjusting the operating gear of the suction and exhaust assembly to the preset super-strong gear; when the suction assembly operates at the preset super-strong gear, the operation gear of the suction assembly is maintained unchanged.
