Detailed Description

In the following description, numerous details are provided to provide a thorough understanding of the present invention. One skilled in the art, however, will understand that the following description illustrates only a preferred embodiment of the invention and that the invention may be practiced without one or more of these details. In addition, some technical features that are well known in the art are not described in detail in order to avoid obscuring the present invention.

During cooking, especially frying and stir-frying, a large amount of oil smoke is generated. The soot contains a large amount of fine particles therein. Fine particulate refers to particles having an aerodynamic equivalent diameter of 2.5 microns or less in ambient air and is therefore commonly referred to as PM 2.5. The research shows that: during frying and frying, the concentration of PM2.5 can rapidly rise by 8 times to 20 times or even more. The so-called cooking-generated fumes are directly related to PM 2.5. Moreover, carcinogens such as benzopyrene and heterocyclic amine contained in the oil smoke are adsorbed to PM2.5, and have a greater influence on health.

The utility model provides a cigarette machine, this cigarette machine can the automated inspection fine particles concentration in the air to according to fine particles concentration, the operating speed of automatically regulated motor, so that in time under the circumstances of saving electric power, fast, reduce the oil smoke that produces when culinary art high-efficiently.

Figure 1 shows a machine according to one embodiment of the present invention. As shown in fig. 1, the range hood 100 includes a main machine, a dust sensor 120, and a control device 130.

The motor 110 is provided in the main body. An impeller is also typically disposed within the main body, and a motor 110 is connected to the impeller. The motor 110 can drive the impeller to rotate at a high speed to suck the oil smoke into the flue. The motor 110 may be an ac motor or a dc motor. The rotational speed of the motor 110 is adjustable. For an ac motor, the motor 110 may only be capable of operating in a predetermined number of speed steps, such as high, medium, and low speed steps. For a dc motor, the speed of the motor 110 can be continuously variable, and the speed of the motor 110 can be controlled by the amount of current delivered to the motor 110.

The dust sensor 120 is provided on the main machine for detecting the concentration of fine particulate matter in the air. The dust sensor 120 is also commonly referred to as a PM2.5 sensor. The most common PM2.5 sensors available are designed based on the principle of light scattering. The particles and molecules generate light scattering phenomenon under the irradiation of light, and at the same time, absorb part of the energy of the irradiated light. When a beam of parallel monochromatic light is incident to the measured particle field, the light intensity is attenuated under the influence of scattering and absorption around the particles. Therefore, the relative attenuation rate of the incident light passing through the concentration field to be measured can be obtained. And the relative attenuation rate is basically linear to reflect the relative concentration of the dust in the field to be measured. The intensity of the light intensity is in direct proportion to the intensity of the electric signal after photoelectric conversion, and the relative attenuation rate can be obtained by measuring the electric signal, so that the concentration of fine particles in the field to be measured can be measured. Alternatively, the dust sensor 120 may employ other types of dust sensors that are present or may come into existence in the future, as long as the PM2.5 concentration in the air can be detected. Illustratively, the dust sensor 120 may detect the PM2.5 concentration in the air at regular intervals, for example, at intervals of 1 second.

The control device 130 is connected to the motor 110 and the dust sensor 120. Here and in the following, the "connections" between the electric devices may be wired and/or wireless. The control device 130 receives a concentration signal indicative of the concentration of PM2.5 detected by the dust sensor 120. The control device 130 controls the rotation speed of the motor 110 in the operating state according to the concentration signal. When the range hood 100 is operating, the control device 130 continuously receives the concentration signal from the dust sensor 120 and adjusts the operating speed of the motor 110 based on the concentration signal. The higher the PM2.5 concentration detected by the dust sensor 120, the faster the control device 130 controls the rotation speed of the motor 110. Conversely, the lower the PM2.5 concentration detected by the dust sensor 120, the slower the control device 130 controls the rotation speed of the motor 110. Therefore, when the concentration of PM2.5 in the air is higher, the rotating speed of the motor 110 is increased, and the discharge of harmful gas is accelerated; when PM2.5 concentration is lower, reduce motor 110 rotational speed, practice thrift the electric energy, reduce the noise, improve user's use and experience.

The utility model discloses a set up dust sensor on the cigarette machine, it can detect the great PM2.5 concentration of direct reaction oil smoke concentration and to health hazard in the culinary art environment accurately to can adjust motor's rotational speed automatically according to PM2.5 concentration, thereby under the saving electric energy prerequisite, improve the efficiency of cigarette machine exhaust oil smoke.

Illustratively, as shown in fig. 1, the control device 130 may include a comparator 132 and a driver 134. The comparator 132 is connected to the dust sensor 120. The comparator 132 receives the concentration signal indicative of the PM2.5 concentration detected by the dust sensor 120, and compares it with a preset threshold value to output a comparison signal. The comparator 132 may be implemented by using an operational amplifier, or the operational amplifier may be further implemented by using a resistor, a capacitor, and the like. The driver 134 is connected to the comparator 132 and the motor 110. The driver 134 receives the comparison signal from the comparator 132 to control the motor 110 to operate at different speed steps according to the comparison signal. The driver 134 may control the rotational speed of the motor 110 in different manners depending on the type of the motor 110. Since the manner of adjusting the rotation speed of the motor 110 is well known in the art, the improvement of the present invention is not how to adjust the rotation speed of the motor 110, and therefore, it will not be described in further detail herein. The control device 130 has the advantages of simple structure, strong working stability and high durability.

The preset threshold may be one or more, which is related to the gear of the rotation speed of the motor 110. For example, when the predetermined threshold is one, i.e. a₀When desired, the motor 110 may have two speeds, a high speed and a low speed. Specifically, when the PM2.5 concentration received by the comparator 132 is higher than or equal to the preset threshold a₀When the motor is running, the comparator 132 outputs a comparison signal 1, and the drive controller 134 controls the motor 110 to operate at a high speed; when the concentration of PM2.5 received by the comparator 132 is lower than the preset threshold value a₀At this time, the comparator 132 outputs a comparison signal 0, and the driver 134 controls the motor 110 to operate at the low speed. When the predetermined threshold is two, i.e. a₁And a₂(wherein a)₁Greater than a₂) When desired, the motor 110 may have a third gear speed, i.e., a high gear, a middle gear, and a low gear. Specifically, when the PM2.5 concentration received by the comparator 132 is higher than or equal to the preset threshold a₁Meanwhile, the comparator 132 outputs the comparison signal 11, and the driving controller 134 controls the motor 110 to work at a high speed; when the concentration of PM2.5 received by the comparator 132 is lower than the preset threshold value a₁And is higher than or equal to a preset threshold value a₂Meanwhile, the comparator 132 outputs a comparison signal 10, and the driving controller 134 controls the motor 110 to work at a middle speed; when the concentration of PM2.5 received by the comparator 132 is lower than the preset threshold value a₂The comparator 132 outputs a comparison signal 00. When more gear speeds need to be set, more preset thresholds may be set. The utility model discloses not restrict the rotational speed gear with predetermine the threshold value, technical personnel in the field can set up rationally as required.

The dust sensor 120 may be disposed at various locations on the host, but preferably, the dust sensor 120 may be disposed at a side of the host. When the motor 110 is operated, the oil smoke is sucked into the flue from the bottom to the top. Like this, set up dust sensor 120 in the host computer side, can also effectively avoid oil smoke and dust to accumulate in dust sensor 120 and influence its life. In addition, it is possible to prevent the moving oil smoke and the hot air generated during cooking from affecting the detection result of the dust sensor 120.

When the rotating speed of the range hood is controlled according to the PM2.5 concentration, the influence of the air quality in the natural environment can be influenced. For example, when the amount of smoke generated during cooking is small, that is, the concentration of PM2.5 generated due to cooking is low, if the air quality of the natural environment is very poor, the concentration of PM2.5 detected by the dust sensor 120 is also very high, and if the rotation speed of the motor 110 is still controlled according to the concentration of PM2.5, the user experience may be poor. In view of this, in one preferred embodiment, as shown in figure 4, the cigarette maker 400 is also provided with a temperature sensor 410. The temperature sensor 410 is provided on the host computer for detecting the ambient temperature. The temperature sensor 410 is connected to the control device 130. The control device 130 controls the rotation speed of the motor 110 in the operating state according to the PM2.5 concentration and the ambient temperature.

The oil smoke concentration produced during stir-frying is higher, and the influence of stir-frying on the environment temperature is also larger, so that the environment temperature is higher. If the concentration of PM2.5 detected by the dust sensor 120 is high, but the ambient temperature detected by the temperature sensor 410 is low, it indicates that the high concentration of PM2.5 may be caused by the environment. At this time, the control device 130 may control the motor 110 to operate at a lower rotation speed. Therefore, the motor 110 can be prevented from working at a higher rotating speed when the concentration of PM2.5 detected by the dust sensor 120 is higher due to environmental pollution and the like, so that electric energy waste is avoided, and meanwhile, the automation degree of a product is improved.

Illustratively, the temperature sensor 410 may be an infrared temperature sensor. The infrared temperature sensor detects the temperature rise by using the radiant heat effect. Under this condition, can set up temperature sensor 410 in the bottom of host computer to can be directly to the cigarette machine below, the temperature rise in culinary art region promptly detects, with accurately judging the culinary art state, reduces the natural environment temperature and causes the influence to the testing result. Therefore, the intelligentized precision of the cigarette machine is improved.

In one exemplary embodiment, the machine 100 may also include a trigger switch 210, as shown in figure 2, the trigger switch 210 being connected to the control device 130. The trigger switch 210 outputs a trigger signal to the control device 130 according to an operation of a user. The trigger signal may be high or low. The control device 130 starts receiving the concentration signal indicating the concentration of PM2.5 detected by the dust sensor 120 after receiving the signal that the trigger switch 210 is triggered. The trigger switch 210 may take the form of a button, a touch screen, a voice receiving device, or the like. The trigger switch 210 can actually turn on the smart mode of the cigarette maker 200, in which the cigarette maker 200 can automatically control the rotation speed of the motor 110 according to the detection result of the dust sensor 120. When the trigger switch 210 is not activated, the range hood 200 is in the manual mode. When the user triggers the trigger switch 210, the control device 130 controls the rotation speed of the motor 110 according to the received concentration signal. The speed of motor 110 is not correlated to the PM2.5 concentration in the air until trigger switch 210 is not triggered. At this time, the user can adjust the rotation speed of the motor 110 as desired. The cigarette machine 200 has two operation modes of manual operation and automatic operation, can meet various requirements of users, and has good user experience.

In another exemplary embodiment, as shown in fig. 3, a trigger switch 310 may be connected to the dust sensor 120. The trigger switch 310 outputs a trigger signal to the dust sensor 120 according to the operation of the user. The trigger signal may be high or low. The dust sensor 120 starts detecting the PM2.5 concentration in the air after receiving a signal that the trigger switch 310 is triggered. The trigger switch 310 may take the form of a button, a touch screen, a voice receiving device, etc. Illustratively, the trigger switch 310 may control the on/off of the dust sensor 120. When the trigger switch 310 is not triggered, the dust sensor 120 is not operating while the range hood 300 is in the manual mode. When the user triggers the trigger switch 210, the range hood 300 enters the automatic mode. In this way, the user may select the mode of the range hood 300 as desired. The cigarette machine 300 has two operation modes of manual operation and automatic operation, can meet various requirements of users, and has good user experience. In addition, the dust sensor 120 operates only in the automatic mode to extend the life of the dust sensor 120.

Illustratively, in embodiments of a cigarette maker having a trigger switch, such as the embodiments shown in figures 2 and 3, the cigarette maker may further include a speed adjustment member. An embodiment including the rotational speed adjusting member 230 will be described below with reference to fig. 2. The rotational speed adjusting member 230 is provided on the main body. The speed adjuster 230 may receive a user operation to manually adjust the speed of the motor 110. The rotational speed adjusting member 230 is connected to the control device 130 to transmit an operation signal representing a user operation to the control device 130. The control device 130 controls the rotation speed of the motor 110 according to the received operation signal. When the range hood 200 automatically adjusts the rotation speed of the motor 110 according to the detection result of the dust sensor 120, the user may directly and manually operate the rotation speed adjusting member 230 to exit the automatic adjustment mode to manually change the rotation speed of the motor 110. Of course, the rotation speed adjusting member 230 may also receive the operation of the user in the case where the trigger switch 210 is not triggered.

The rotation speed adjustment member 230 may take the form of a button, a touch screen, and a voice receiving device. The speed adjuster 230 may be arranged to adjust the speed of the motor 110, for example to adjust the speed to any of the three low, medium and high gears. Of course, the rotation speed adjusting member 230 may also steplessly adjust the rotation speed of the motor 110. Through setting up rotational speed regulating part 230, the user can carry out manual control to the rotational speed of motor when not getting into the intelligent mode that carries out automatically regulated according to dust sensor to motor rotational speed or when expecting to withdraw from this intelligent regulation mode to satisfy user's multiple demand, user experience is good.

Illustratively, the cigarette maker 200 may also include a mechanism 220, see back figure 2, which is electrically connected to the control device 130. After the mechanism 220 is triggered, the control device 130 continues to receive the concentration signal indicative of the concentration of PM2.5 detected by the dust sensor 120. When the PM2.5 concentration is lower than the target concentration, the control device 130 controls the motor 110 to stop operating. Therefore, even under the unattended condition, the motor can stop rotating after the concentration of PM2.5 is reduced to the target concentration, so that the effects of saving electric energy and improving the automation degree of products are achieved.

Illustratively, the cigarette maker 100 may also include a control panel 240, see figure 2. The control panel 240 is provided on the host computer. The control panel 240 is typically located on the front of the host computer at a location convenient for the user to operate.
