Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described more fully below by way of examples in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

In one embodiment, a range hood control device is provided, including purifier, concentration detection device and controller, purifier, concentration detection device and controller all set up in the range hood, and concentration detection device and purifier all connect the controller, and purifier is used for purifying the oil smoke, and concentration detection device is used for detecting the gas concentration after purifier to send to the controller, and the controller is according to the working parameter of the motor of range hood and/or according to the working strength of gas concentration adjustment purifier. Purifier can purify the oil smoke, reduce the atmosphere pollution that the direct vent oil smoke of lampblack absorber caused, concentration detection device can detect the gas concentration behind purifier, and send to the controller, the working parameter of controller motor according to the lampblack absorber and/or according to gas concentration adjustment purifier's working strength, realize purifier's purification as required, thereby when reaching the purification oil smoke, purifier's intelligence can also be improved, purifier's energy consumption is reduced, energy saving, thereby the use reliability of lampblack absorber has been improved.

Specifically, the controller can adopt a control chip originally arranged in the range hood, and corresponding functions are added on the original control chip so as to realize the range hood control method and save hardware cost. Or, a controller independent of the original range hood can be adopted, the steps of the range hood control method can be executed through the controller, the original functions of the range hood cannot be influenced, the range hood can also be in work division cooperation with a control chip of the range hood, the work is not influenced, and the work accuracy is improved.

The working parameters of the motor are parameters related to the working of the motor, and the method for acquiring the working parameters of the motor of the range hood is different according to different types of the working parameters of the motor. For example, when the operating parameter of the motor is the motor rotation speed, the rotation speed of the motor can be directly read by a controller connected with the motor, and the controller can directly acquire the motor rotation speed. Or, when the working parameter of the motor is the ambient temperature of the environment where the motor is located, the ambient temperature may be detected by a temperature detector disposed on or near the motor, and then the ambient temperature is sent to the controller, and the method for the controller to obtain the ambient temperature of the motor is obtained by the temperature detector. It is understood that in other embodiments, the operating parameters of the motor may be of other types, and the corresponding acquisition of the operating parameters of the motor may also be implemented in other manners, as long as the implementation is considered by those skilled in the art.

The purifying device 12 is disposed in the range hood and used for purifying the oil smoke. The type of the purification apparatus 12 is not exclusive as long as the function of purifying the oil smoke is achieved. After the controller obtains the working parameters of the motor, the controller judges the working state of the motor according to the working parameters of the motor, and then adjusts the working strength of the purifying device 12 according to the working state of the motor. The manner in which the operating intensity of the purification apparatus 12 is adjusted may vary depending on the type of operating parameter. For example, when the operating parameter is the motor speed, the controller monitors the motor speed, and when the controller monitors that the motor speed becomes large, the working strength of the range hood becomes large, the sucked oil smoke increases, the input voltage transmitted to the purifying device 12 is increased at the moment, and the purifying capacity of the purifying device 12 is improved, so that the sucked oil smoke is more comprehensively purified. When the controller monitors that the rotation speed of the motor is reduced, the working strength of the range hood is considered to be reduced, the sucked oil smoke is reduced, the input voltage transmitted to the purifying device 12 is reduced, the purifying capacity of the purifying device 12 is reduced, the energy consumption of the purifying device 12 is reduced, and the effect of saving resources is achieved. It is understood that in other embodiments, different adjustment manners may be adopted for the purification device 12 according to different types of operating parameters or other special conditions, and the adjustment manners may be specifically adjusted according to actual conditions, as long as the adjustment is realized by those skilled in the art.

After the purification device 12 starts to operate and purifies the oil smoke, the concentration of the gas passing through the purification device 12 is obtained, and the detected gas concentration value can be used as one of the bases for judging the purification effect of the purification device 12. The mode of obtaining the gas concentration is not exclusive, and in this embodiment, the accessible concentration detection device 13 detects the gas concentration, and concentration detection device 13 sets up behind purifier 12 for detect the gas concentration behind purifier 12, and concentration detection device 13 still connects the controller, is used for sending the gas concentration who detects to the controller, is convenient for carry out subsequent processing.

After the controller obtains the gas concentration, the controller compares the gas concentration with a preset concentration threshold value, and adjusts the working strength of the purification device 12 according to the relationship between the gas concentration and the preset concentration threshold value. Specifically, when the gas concentration is greater than the preset concentration threshold, it is considered that the current gas concentration is too large, and the purification effect of the purification device 12 is not good, and at this time, the input voltage transmitted to the purification device 12 is increased, so that the purification capacity of the purification device 12 is improved, and the inhaled oil smoke is more comprehensively purified. If the preset concentration threshold includes the upper concentration limit and the lower concentration limit, when the gas concentration is smaller than the lower concentration limit, the current gas concentration is considered to be smaller, the purification effect of the purification device 12 is better, and at the moment, the working strength of the purification device 12 can be properly reduced, so that the effect of saving energy consumption is achieved.

In one embodiment, referring to fig. 3-6, the purification device includes a generator and a collector, the generator is disposed at the upper air inlet of the range hood, the collector is disposed at the lower air inlet of the range hood, and the controller is connected to the generator.

Specifically, when the purifying device 12 works, the oil smoke reaches the generating electrode first and then reaches the collecting electrode. Wherein, the generating electrode is connected with high voltage electricity (generally adopting 7-9 KV high voltage electricity), taking the purifying device 12 arranged at the air inlet of the range hood as an example, when oil smoke enters from the air inlet and passes through the generating electrode of the purifying device 12, ions and electrons in the gas are accelerated under the action of a strong electric field near the discharge electrode, so that the ions or electrons have enough kinetic energy to collide with gas molecules and are ionized, and further more ions and electrons are generated to form a corona discharge area. Under the action of corona of the high-voltage electric field, dust-containing airflow enters a corona discharge area, and electric charges are generated on dust particles. The controller is connected with the generating pole, and can adjust the working strength of the purifying device 12 by controlling the voltage transmitted to the generating pole.

Generally, low voltage is applied to the collector to generate opposite polarity electricity on the collector, and the principle of opposite attraction is adopted to adsorb charged particles, and the voltage can be generally connected with 3-4 KV. The electric property of the collector and the electric property of the charged particles are mutually opposite, so that the collector and the charged particles are mutually attracted under the action of the coulomb force of the electric field, and the charged particles are adsorbed. The coulomb force is the electric field force acting between two charges, the magnitude of the interaction force between two static point charges Q1 and Q2 in vacuum is in direct proportion to the product of Q1 and Q2 and in inverse proportion to the square of the distance r between the two static point charges, the direction of the interaction force is along the connecting line of the two static point charges, the same charges repel each other, and the different charges attract each other. It is understood that in other embodiments, the purification apparatus 12 may also include other structures, as long as those skilled in the art recognize that they can be implemented.

In one embodiment, the purification device is arranged at the air inlet or the air outlet of the range hood.

The purification device 12 can be arranged at an air inlet of the range hood, and the range hood is purified and then absorbed by the range hood, so that the influence of oil smoke on internal devices of the range hood is reduced. Or, the purifying device 12 can also be arranged at the air outlet of the range hood to purify the oil smoke sucked by the range hood and then treat the oil smoke, so that the influence of the oil smoke on the air pollution is reduced.

In one embodiment, the operating parameter includes motor speed or motor gear. The type of operating parameter is not exclusive and in the present embodiment the operating parameter includes motor speed or motor gear. It should be understood that the motor speed will ultimately also be reflected as a change in the speed of the motor. When the working parameters comprise the rotating speed or gear of the motor, the corresponding mode for acquiring the working parameters of the motor of the range hood is different and can be determined according to the situation. For example, the dc motor can directly read the motor speed, and the ac motor cannot detect the speed, so that the operating parameters can be obtained by detecting the gear change of the motor.

The single chip microcomputer has rich functions as a controller and has high running speed. Before the working parameters of the motor of the range hood are obtained, the single chip microcomputer can start the range hood firstly, and the starting of the range hood can be understood as switching on the power supply of the range hood. After the range hood is started, the single chip microcomputer controls the motor of the range hood to operate at a set initial rotating speed, so that the motor operates, the range hood generates negative pressure to absorb cooking oil smoke, and the set initial rotating speed can be a rated initial rotating speed set when the motor leaves a factory. After the motor runs, the single chip microcomputer starts to acquire working parameters of the motor. And the singlechip can continuously acquire the working parameters of the motor, so that the monitoring effect on the motor is improved. The singlechip can also obtain the working parameters of the motor as required after receiving the trigger signal, thereby saving energy consumption. The single chip microcomputer can also obtain working parameters of the motor according to a preset time interval, and the intelligent degree is improved. After the range hood is started, the purification device 12 is controlled to be powered on, the purification device 12 is generally controlled to be powered on with an initial setting, the initial setting can be a rated initial setting of the purification device 12 when leaving a factory, and can comprise voltage, current and the like, and after the purification device 12 is powered on, the single chip microcomputer can send an adjusting signal to the purification device 12 according to working parameters of the motor to adjust the working strength of the purification device 12.

In one embodiment, the controller is an MCU that adjusts the operating intensity of the purification apparatus according to the magnitude of the rise or fall of the operating parameter.

The MCU is used as a controller, the operation speed is high, and the working efficiency is high. And the MCU adjusts the working strength of the purification device according to the rising amplitude or the falling amplitude of the working parameters. The working state of the range hood can be obtained according to the working parameters of the motor, and the working state can be specifically a specific numerical value of the working parameters, an interval value where the working parameters are located, or the change condition of the working parameters and the like. In this embodiment, taking the example of obtaining the operating state of the range hood according to the variation of the motor parameter, the MCU may send the adjustment signal to the purification apparatus 12 according to the rising amplitude or the falling amplitude of the motor parameter, specifically, increase the adjustment signal by a corresponding amplitude according to the rising amplitude of the motor parameter, or decrease the adjustment signal by a corresponding amplitude according to the falling amplitude of the motor parameter. Taking the working parameter as the motor rotation speed and the adjustment signal as the energization amount as an example, when the motor rotation speed increases by a certain value (e.g., +30r/min), the purification device 12 correspondingly increases by a certain energization amount (e.g., increases by 10%), and when the motor rotation speed decreases by a certain value (e.g., -30r/min), the purification device 12 correspondingly decreases by a certain energization amount (e.g., decreases by 10%). It is understood that in other embodiments, the working strength of the purification apparatus 12 can be adjusted in other manners, and is not limited herein.

Above-mentioned lampblack absorber controlling means, including purifier, concentration detection device and controller, purifier can purify the oil smoke, reduce the atmosphere pollution that the direct exhaust oil smoke of lampblack absorber caused, concentration detection device can detect the gas concentration behind purifier, and send to the controller, the controller is according to the working parameter of the motor of lampblack absorber and/or according to gas concentration adjustment purifier's working strength, realize purifier's purification as required, thereby when reaching the oil smoke of purification, can also improve purifier's intelligence, reduce purifier's energy consumption, and therefore, energy is saved, thereby the use reliability of lampblack absorber is improved.
