Problems solved by technology

The above-mentioned automatic air volume adjustment control device and control method have a certain hysteresis, because the compensation amount of the air volume is calculated from the deviation of the oil fume or water vapor concentration detected by the sensor group from the initial setting range, and the current required air volume value is determined, and the fan It takes a certain amount of time for the speed of the motor to reach the value of the required air volume gear. For example, when stir-frying, the fan motor of the range hood has not rotated at the beginning or is still at a small air volume speed. The oil fume concentration information is transmitted to the control device. Before the control device makes the speed of the fan motor reach a value sufficient to discharge the large air volume required for the current oil fume, some oil fume has spread outward, polluting the kitchen environment

Embodiment 1

[0072] Such as Figure 1 to Figure 4 As shown, the central flue system of this embodiment includes a range hood 1 and a cooker 2 installed in the kitchen. The internal flue of the range hood 1 communicates with the public flue 3 to form a smoke exhaust channel. A blower fan is installed inside, and a pot 4 is arranged on the cooking range 2, and a motion sensor for detecting the motion mode of the pot is installed on the handle 41 of the pot 4 . In this embodiment, the motion sensor adopts the gyroscope 7, which is a common sensor, which not only has low cost, but also has relatively good accuracy. The common action pattern of the user during the cooking process is relatively fixed, for example: the up and down movement of a certain frequency generally only occurs in the stir-frying scene, the pot 4 as a whole rotates around the axis of the handle 41, or the translation is generally used to serve vegetables or prepare to go to the sink to wash the pot Or move in reverse after...

Embodiment 2

[0101] Such as Figure 6 As shown, it is the same as the first embodiment, and the difference of this embodiment is that different motion sensors are used. The motion sensors in this embodiment are the first acceleration sensor 8 and the second acceleration sensor 9 , wherein the first acceleration sensor 8 and the second acceleration sensor 9 are installed on the outer surface of the pot 4 close to the upper edge. The first acceleration sensor 8 is used to detect the accelerated motion of the pot 4 in the vertical direction, and the second acceleration sensor 9 is used to detect the accelerated motion of the pot 4 in the horizontal direction.

[0102] Such as Figure 7 As shown, the target air volume control method in this embodiment includes the following steps:

[0103] 1) Start the range hood;

[0104] 2) The range hood runs at the default gear;

[0105] 3), read the information of the first acceleration sensor, the second acceleration sensor and the temperature sensor...

Abstract

A target air volume control method for a central flue system, comprising a range hood and a cooker installed in a kitchen, the internal flue of the range hood is connected with a public flue to form a smoke exhaust channel, and a smoke exhaust channel is installed in the smoke exhaust channel The fan is equipped with a pot on the cooker, which is characterized in that: a motion sensor is installed on the cooker to detect the movement mode of the pot, a temperature sensor is installed on the cooker to detect the temperature of the bottom of the pot, and it also includes a sensor for detecting the motion of the cooker. Sensor and temperature sensor information to control the controller of the air volume of the fan. The target air volume control method of the central flue system can analyze the information of the user’s action of holding the pan through the motion sensor installed on the pan and predict the possible occurrence of heavy oily smoke, thereby pre-predicting the sudden change of oily smoke, and , It can also make adaptive adjustments to the fan gear and target air volume after the threshold value is judged by the temperature value of the bottom of the pot measured by the temperature sensor, thereby improving the user experience.

Description

technical field [0001] The invention relates to a central flue system, in particular to a central flue system and a method for controlling the target air volume. Background technique [0002] Range hoods are essential electrical appliances for people to cook and smoke in daily life. The motors of traditional range hoods use fixed gears or rotational speeds, which have poor anti-interference and self-adaptability to flue resistance and natural wind convection when doors and windows are opened at the same time. The amount of oily smoke generated by the user during the cooking process is a changing curve. Through experiments, it is easy to find that the general smoke mainly appears at the moment when the dishes, seasonings, water, etc. are put into the pot, and when the user stirs the pot, the amount of smoke is relatively small at other cooking times. , and the change is not big, and the number of users connected to high-rise public flue is generally relatively large (it is co...
