[0046] Example 1

[0047] This embodiment provides a smoke pipe detection method, which is applied to a range hood. The range hood includes a pressure sensor. The pressure sensor is arranged at the outlet of the air outlet hood of the range hood. Figure 1 , the smoke tube detection methods include:

[0048] S1. In response to the range hood running for a preset time, an actual pressure value collected by a pressure sensor is obtained, and a first difference between the actual pressure value and an initial pressure value is determined.

[0049] In an optional implementation, the preset duration is 2 minutes.

[0050] The initial pressure value is the initial recorded value collected by the pressure sensor after the range hood is installed.

[0051] S2. Obtain the actual motor speed of the range hood, and determine a second difference between the actual motor speed and the theoretical motor speed.

[0052] In an optional embodiment, the first threshold is 5 Pa.

[0053] In an optional embodiment, the theoretical motor speed is determined by the following formula:

[0054] ni=n0+(P1-P2) / (n2-n1)*(P1-P0).

[0055] Among them, ni is used to represent the theoretical motor speed. n0 is used to represent the actual motor speed. n1 is used to represent the first motor speed experimental value. n2 is used to represent the second motor speed experimental value. P0 is used to represent the actual pressure value. P1 is used to represent the first smoke pipe pressure experimental value. P2 is used to represent the second smoke pipe pressure experimental value.

[0056] Among them, n1, n2, P1 and P2 are constant values.

[0057] S3: In response to the first difference being greater than a first threshold and the second difference being greater than a second threshold, determining that the smoke duct of the range hood is faulty.

[0058] In an optional embodiment, the second threshold is 50 revolutions per minute.

[0059] When the smoke duct of the range hood is damaged, the pressure of the smoke duct and the speed of the motor will change. The present invention utilizes this principle and comprehensively considers the changes in the smoke duct pressure and the motor speed. It can not only realize intelligent reminder of smoke duct failure, but also ensure the accuracy of judgment of smoke duct failure.

[0060] In an optional embodiment, the smoke tube detection method further includes:

[0061] In response to the first difference being less than or equal to a first threshold and the second difference being greater than a second threshold, it is determined that the smoke duct of the range hood is faulty.

[0062] In an optional embodiment, the smoke tube detection method further includes:

[0063] In response to the first difference being greater than the first threshold and the second difference being less than or equal to the second threshold, it is determined that the resistance to the range hood's fume extraction increases, the initial pressure value and the theoretical motor speed are updated, and the step of determining the first difference between the actual pressure value and the initial pressure value is returned.

[0064] Since the pressure of the smoke pipe changes with the increase of usage time, in this embodiment, updating the actual pressure value to the initial pressure value and updating the actual motor speed to the theoretical motor speed is beneficial to improving the accuracy of subsequent detection of smoke pipe faults.

[0065] In an optional embodiment, the smoke tube detection method further includes:

[0066] In response to the first difference being less than or equal to the first threshold, and the second difference being less than or equal to the second threshold, it is determined that the smoke duct of the range hood is normal.

[0067] In an optional embodiment, step S3 includes:

[0068] Send out alarm signals of smoke pipe failure. Alarm signals include lighting, buzzing, displaying alarm patterns, displaying alarm text, etc.

[0069] In this embodiment, since the smoke duct is generally pre-buried in the suspended ceiling, a significant alarm signal is required to remind the user to repair the smoke duct so that the range hood can operate normally.

[0070] A specific example is introduced below to explain the smoke pipe detection method of this embodiment in detail.

[0071] Figure 2 Schematic diagram of the position of the pressure sensor in this example, the pressure sensor 201 is arranged between the range hood 202 and the check valve 203. Figure 3 This is the flowchart for this example.

[0072] S301, start range hood duct fault detection.

[0073] S302, recording the initial pressure value of the smoke pipe after the range hood is installed.

[0074] S303. After the range hood has been running for two minutes, the actual pressure value of the smoke pipe is recorded.

[0075] S304: Calculate a first difference ΔP.

[0076] S305 , determining whether ΔP is less than or equal to a first threshold value Pmin, if ΔP is less than or equal to Pmin, executing step S306 ; if ΔP is greater than Pmin, executing step S309 .

[0077] S306. Determine whether the second difference between the actual motor speed and the theoretical motor speed is less than or equal to a second threshold value of 50 rpm (revolutions per minute). If the second difference is less than or equal to 50 rpm, execute step S307; if the second difference is greater than 50 rpm, execute step S308.

[0078] S307, confirm that the smoke pipe is normal.

[0079] S308. Determine that the smoke pipe is faulty and turn on the fault light.

[0080] S309: ΔP is greater than Pmin, and step S310 is executed.

[0081] S310, calculate the theoretical motor speed according to the following formula:

[0082] ni=n0+(P1-P2) / (n2-n1)*(P1-P0).

[0083] This formula is based on the normal range hood performance curve (such as Figure 4It should be noted that Figure 4 The horizontal axis is used to represent the motor speed. Figure 4 The vertical axis is used to represent the duct pressure value. During the range hood development stage, the range hood performance curve is simulated by interpolation of multiple orifice plates with different apertures of the air volume table to simulate the range hood working conditions under different working conditions. Therefore, a normal range hood can infer the theoretical motor speed through the actual pressure value, the actual motor speed, and the two nearest interpolation points (P1, n1) and (P2, n2) on the left and right.

[0084] S311. Determine whether the second difference between the actual motor speed and the theoretical motor speed is less than or equal to a second threshold value of 50 rpm (revolutions per minute). If the second difference is less than or equal to 50 rpm, execute step S312; if the second difference is greater than 50 rpm, execute step S313.

[0085] S312: Determine that the resistance of the range hood to absorbing oil fumes has changed, determine that the smoke pipe is in a normal state, and execute step S314.

[0086] S313. Determine that the smoke pipe is faulty and turn on the fault light.

[0087] S314, updating the actual pressure value collected this time to the initial pressure value, updating the actual motor speed collected this time to the theoretical motor speed, and returning to step S302.
