Description

Technical Field

[0001] This invention relates to the field of range hood technology, and in particular to a control method, device, range hood, and storage medium for a range hood. Background Technology

[0002] Currently, existing fixed-frequency range hoods simulate the function of variable-frequency products by using a fixed-frequency motor. Adding a current transformer to the power board, such as... Figure 1a As shown, by sensing the change in current (power) during the operation of the same gear, the change in current is used to determine the change in the working environment. Based on the preset back pressure logic and threshold, the gear is automatically switched to realize the cruise function of the fixed frequency range hood.

[0003] The current fixed-frequency cruise control function uses fixed threshold parameters and motor current, which are crucial to its calculations. This makes it unable to accurately assess the actual conditions of the user's flue (flue width, smoke extraction smoothness). For example, when the flue is wide, smoke extraction is smooth, and power is high, making it easier to switch to a lower speed. According to the design logic, if the flue doesn't become more clogged, it won't switch to a lower speed; conversely, it's easier to switch to a higher speed if the flue is wide. This situation arises because the threshold is fixed. Summary of the Invention

[0004] This invention provides a control method, device, range hood, and storage medium for a range hood, thereby offering a novel control method for a range hood that dynamically adjusts the switching voltage threshold to flexibly adapt to changes in the flue environment, aging of the range hood, and individual differences, accurately switching operating levels and thus improving the user experience.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Example 1

[0031] Figure 1b This is a flowchart of a control method for a range hood according to Embodiment 1 of the present invention. This embodiment is applicable to situations where the range hood is used for gear control. The method can be executed by a control device for the range hood, which can be implemented in hardware and / or software. This control device can be configured in the main controller of the range hood. Figure 1b As shown, the method includes:

[0032] S110. Determine the voltage value of each operating setting of the range hood within the set time period.

[0033] Optionally, before determining the voltage value of each operating setting of the range hood within a set time, the process may further include: controlling each operating setting of the range hood to run sequentially for the same set time.

[0034] The operating speed can be, for example, high speed, medium speed, and low speed, or it can be a stir-fry speed, a high speed speed, and a gentle speed speed, etc. This embodiment does not limit the specific speeds or the number of operating speeds. The set duration can refer to the working time of each operating speed, and each operating speed can operate for the same set duration. This set duration can generally be a short duration, for example, 10 seconds. The speed voltage value can be an average voltage value.

[0035] In this embodiment, all operating speeds of the range hood can be controlled to run sequentially from high speed to low speed or from low speed to high speed for a set duration. Furthermore, the voltage value of each operating speed can be determined during the operation of each set duration.

[0036] Optionally, determining the voltage value of each operating setting of the range hood within a set time period may include: during the second half of the set time period, collecting the real-time motor current value of the range hood at the current operating setting and converting the real-time motor current value into a real-time voltage value; and determining the voltage value of the current operating setting based on the real-time voltage value and the number of real-time voltage values.

[0037] Taking the operating speeds (high, medium, and low) as an example, the range hood is controlled to run in the following order: high speed → medium speed → low speed, each for 10 seconds. That is, after running at high speed for 10 seconds, it switches to medium speed for 10 seconds, and then switches to low speed for 10 seconds. During the 10 seconds of high speed operation, the first 5 seconds are a stable period and no data is recorded. During the last 5 seconds, the power board can detect the real-time motor current value of the range hood through a current transformer. Based on a sampling frequency of 10 times / second, a total of 50 data points (V) are collected during the 10 seconds of high speed operation. 高速The five maximum and five minimum values ​​are removed, and the collected real-time motor current value is converted into a digital voltage signal (i.e., real-time gear voltage value) that the chip can recognize. (i)高速 Therefore, the final high-speed gear voltage value can be determined as follows: Similarly, the voltage value for the medium speed gear can be determined within 10 seconds of operation in medium speed mode. Similarly, the voltage value of the low-speed gear can be determined within 10 seconds of operation in low speed mode.

[0038] S120: Obtain the default shift voltage threshold and the reference voltage value for each operating level of the range hood.

[0039] The default voltage threshold for gear shifting can be the factory default value of the range hood. The reference voltage value can be a typical value obtained based on the characteristics of the range hood, or a voltage value that is closest to the condition of the user's home's flue.

[0040] Continuing the previous example, the default shift voltage threshold can include V for shifting from a high-speed gear to a medium-speed gear. 高-中 Shifting from medium to low gear V 中-低 Shifting from low gear to medium gear V 低-中 And the V-shaped shift from medium to high speed. 中-高 The reference voltage value can include the high-speed gear reference voltage value V. 高速 Medium speed gear reference voltage value V 中速 and the reference voltage value V for low speed gear 低速 .

[0041] In one scenario, if a gear switching failure occurs during the process of controlling each operating gear to run sequentially for a set duration, the current operating gear and the gear to be switched can be determined. Based on the gear voltage value of the current operating gear, the reference voltage value of the current operating gear, and the reference voltage value of the gear to be switched, the gear voltage value of the gear to be switched can be determined.

[0042] For example, if the current operating gear is medium speed and the intended operating gear is low speed, meaning the switch from medium speed to low speed fails, then the gear voltage value for low speed cannot be determined by collecting the real-time motor current value. Therefore, the gear voltage value for low speed can be determined as follows:

[0043]

[0044] In one scenario, after determining the voltage value of each operating level of the range hood within a set time period, the process may further include: determining whether the voltage value of each operating level is within the preset voltage range of each operating level; if so, then performing the step of determining the new shift voltage threshold of the range hood under the current operating conditions based on the voltage value, the default shift voltage threshold, and the reference voltage value; otherwise, re-determining the voltage value of the operating levels that are outside the preset voltage range.

[0045] Furthermore, re-determining the voltage value of the operating gear that is outside the preset voltage range may include: if the voltage value of the medium speed gear exceeds the high threshold of the medium speed gear voltage, directly using the high threshold of the medium speed gear voltage as the voltage value of the medium speed gear; if the voltage value of the medium speed gear is lower than the low threshold of the medium speed gear voltage, directly using the low threshold of the medium speed gear voltage as the voltage value of the medium speed gear; if the voltage value of the low speed gear is lower than the low threshold of the low speed gear voltage, directly using the low threshold of the low speed gear voltage as the voltage value of the low speed gear.

[0046] For example, if V2 > 0x60, then V2 = 0x60; if V2 < 0x39, then V2 = 0x39; if V3 < 0x25, then V3 = 0x25.

[0047] S130. Determine the new shift voltage threshold of the range hood under the current operating conditions based on the gear voltage value, the default shift voltage threshold, and the reference voltage value.

[0048] In this embodiment, the switching voltage threshold of the range hood can be updated each time it is powered on or at periodic intervals; this embodiment does not limit this. For example, if the range hood's installation location changes and it is powered on again, the switching voltage threshold can be updated based on the flue condition after the change. For example, the switching voltage threshold can be updated periodically based on a one-year cycle. For example, the range hood's operating condition can be periodically monitored, and the switching voltage threshold can be updated when set conditions are met.

[0049] S140: Control the range hood to switch gears according to the new shift voltage threshold.

[0050] In this embodiment, after determining the new shift voltage threshold, the range hood can be controlled to switch gears when the new shift voltage threshold is met.

[0051] The technical solution of this invention provides a new range hood control method that dynamically adjusts the shift voltage threshold within a set time period for each operating level of the range hood; obtains the default shift voltage threshold and the reference voltage value for each operating level of the range hood; determines the new shift voltage threshold of the range hood under the current operating conditions based on the level voltage value, the default shift voltage threshold, and the reference voltage value; and controls the range hood to switch levels based on the new shift voltage threshold. This solves the problem that the fixed-frequency cruise function of existing range hoods cannot accurately judge the actual flue conditions (flue diameter, whether the smoke exhaust is smooth) during the calculation process, resulting in incorrect shifting. The method provides a new control method for range hoods that dynamically adjusts the shift voltage threshold, flexibly adapts to changes in the flue environment, adapts to aging of the range hood, and individual differences, accurately switches operating levels, thereby improving the user experience.

[0052] Example 2

[0053] Figure 2 This is a flowchart of another control method for a range hood provided in Embodiment 2 of the present invention. Based on the above embodiments, this embodiment refines the determination of the new shift voltage threshold for the range hood under the current operating conditions according to the gear voltage value, the default shift voltage threshold, and the reference voltage value. For example... Figure 2 As shown, the method includes:

[0054] S210. Determine the voltage value of each operating setting of the range hood within the set time period.

[0055] S220: Obtain the default shift voltage threshold and the reference voltage value for each operating setting of the range hood.

[0056] S230, Determine the current operating gear and the operating gear to be switched.

[0057] The currently operating gear here refers to the gear being used during the process of determining the new voltage threshold for gear switching. The gear to be switched to in advance refers to the gear that is expected to be switched from the currently operating gear.

[0058] S240. Based on the current operating gear and the pre-switch operating gear, determine the target shift voltage threshold from the default shift voltage threshold, and determine the target reference voltage value from the reference voltage value.

[0059] In this embodiment, the current switching plan can be confirmed based on the current operating gear and the pre-switching gear. Then, the default switching voltage threshold that matches the current switching plan can be found from at least one default switching voltage threshold and determined as the target switching voltage threshold. The reference voltage value that matches the current operating gear can be found from at least one reference voltage value and determined as the target reference voltage value.

[0060] S250. Determine the adjustment coefficient based on the target shift voltage threshold and the target reference voltage value.

[0061] S260. Multiply the adjustment coefficient by the voltage value of the current operating gear to obtain the product result.

[0062] S270. Add the product result to the current gear voltage value to determine the new gear shift voltage threshold corresponding to the target gear shift voltage threshold.

[0063] S280: Control the range hood to switch gears according to the new shift voltage threshold.

[0064] Let's take a specific example to illustrate: Assume the default shift voltage threshold is V. 高-中 =0x92, V 中-低 =0x65, V 低-中 =0x25, V 中-高 =0x37; Reference voltage value: V 高速 =0x72, V 中速 =0x43, V 低速 =0x2F. Therefore:

[0065]

[0066]

[0067]

[0068]

[0069] in, This can be understood as an adjustment coefficient.

[0070] The technical solution of this invention provides a new range hood control method that dynamically adjusts the shift voltage threshold within a set time period for each operating level of the range hood; obtains the default shift voltage threshold and the reference voltage value for each operating level of the range hood; determines the new shift voltage threshold of the range hood under the current operating conditions based on the level voltage value, the default shift voltage threshold, and the reference voltage value; and controls the range hood to switch levels based on the new shift voltage threshold. This solves the problem that the fixed-frequency cruise function of existing range hoods cannot accurately judge the actual flue conditions (flue diameter, whether the smoke exhaust is smooth) during the calculation process, resulting in incorrect shifting. The method provides a new control method for range hoods that dynamically adjusts the shift voltage threshold, flexibly adapts to changes in the flue environment, adapts to aging of the range hood, and individual differences, accurately switches operating levels, thereby improving the user experience.
