Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be understood that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, in the embodiment of the present invention, an intelligent variable-channel variable-frequency discharge system includes a main board 1, a frequency converter 2, an air collecting box 3, and a variable-frequency fan 4, wherein the main board 1 is connected to a cooking range 6 through a temperature sensor 5, a corresponding air cover 7 is disposed above the cooking range 6, the air cover 7 is connected to an air duct channel 8, the air duct channel 8 is connected to an air duct valve 9 at the end, the air duct valve 9 is installed at one side of the air collecting box 3, the air collecting box 3 is connected to the variable-frequency fan 4, the other side of the variable-frequency fan 4 is connected to the frequency converter 2, the air collecting box 3, and the air duct valve 9 are all connected to the main board 1, a timer 14 is disposed on the main board, the system detects the working state of the cooking range 6 through the main board 1, thereby analyzing the required air volume, the gravity baffle 10 is installed at the upper right outlet of the air collecting box 3, the oil collecting port 11 is installed below the gravity baffle 10, when oil smoke comes out of the air collecting box 3 and passes through the gravity baffle 10, particles carried in the oil smoke are attached to the gravity baffle 10, and finally enter the oil collecting port 11 located below the gravity baffle 10 along the gravity baffle 10, and larger particles carried in the oil smoke directly enter the oil collecting port 11 from the outlet at the lower right of the air collecting box 3.
As shown in fig. 2, when beginning to use the kitchen range, the wind channel valve 9 that kitchen range 6 corresponds has also correspondingly opened, and converter 2 and frequency conversion fan 4 are also corresponding to be opened simultaneously, and when kitchen range 6 stalled, wind channel valve 9, converter 2 and the frequency conversion fan 4 that kitchen range 6 corresponds delayed five minutes, reclosed, the utility model is suitable for an at least 3 kitchen ranges 6.
The speed regulation principle of the variable frequency fan 4 is as follows: the relation formula of the motor rotating speed and the frequency is as follows: n =60f/p, n is the motor speed (rpm), f is the power frequency (hertz), and p is the pole pair number of the rotating magnetic field of the motor. Because the power frequency p is a fixed value, the rotating speed of the motor can be changed by changing f according to the formula n =60f/p, so that the aim of adjusting the air quantity by adjusting the speed of the variable frequency fan 4 is fulfilled, and the rotating speed of the motor can be continuously adjusted between 10% and 100% by adopting the centrifugal variable frequency fan driven by the variable frequency motor.
Taking 3 cooking ranges 6 used in a kitchen as an example, when a first cooking range 6 is used, the mainboard senses 5 through the first cooking range to know that the first cooking range 6 starts to be used, the mainboard 1 controls to open the corresponding air channel valve 9, the variable frequency fan 4 is started and is adjusted to the 1-gear variable frequency gear 13 with smaller wind power, at the moment, the air volume control value is 30% to 50%, when a second cooking range 6 is used simultaneously, the mainboard 1 simultaneously opens the corresponding air channel valve 9 and adjusts the wind power to the 2-gear variable frequency gear 13 with larger wind power, and at the moment, the air volume control value is 60% to 80%. When the third stove 6 is used, the corresponding air duct valve 9 is opened by the main board 1, and the air is adjusted to the maximum 3-gear variable frequency gear 13, at this time, the air volume control value is 90% to 100%. And so on. As the cooking range 6 is used with larger and larger oil smoke, the timer 14 of the main board 1 records the process and continuously increases the rotating speed of the variable frequency fan 4 to achieve the maximum air volume (50% of full speed) when one cooking range is used, at this time, if a second cooking range 6 and a third cooking range 6 are used, the working principle is the same as that of the first cooking range, the corresponding control values respectively reach 80% and 100% of full speed, when the used cooking range 6 is reduced, the corresponding air door 4 is closed, the air volume is automatically reduced, and when the cooking range 6 is not used, the main board automatically closes the corresponding air duct valve 9.
The utility model discloses utilize the converter to be through the break-make effect that utilizes power semiconductor device with the power frequency power supply transform for the electric energy controlling means of another frequency, can realize the variable frequency speed governing to exchanging asynchronous machine. When the variable frequency speed regulation is used, if the air quantity requirement is reduced, the requirement can be met by reducing the rotating speed of the variable frequency fan, resources are fully and effectively utilized, energy consumption waste is avoided, and the purpose of intelligent energy conservation is achieved.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
