In order to make the technical problems, technical schemes and beneficial effects solved by the invention more clear, the invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Example 1
Referring to fig. 1, a first embodiment of a control method of a range hood of the present invention includes the steps of:
step 101, generating user control information according to a control instruction of a user.
In this step, the control instruction of the user may be input by a contact manner or a non-contact manner, for example, by a key, touch, infrared induction, or sound control, etc., and after the control instruction of the user is received, the range hood generates user control information according to the control instruction, where the user control information may be used to control the operation of the blower, etc.
And 102, controlling the fan of the range hood to run according to the user control information.
In this step, after receiving a control instruction of a user and generating user control information, the operation of the fan is controlled according to the user control information, such as adjusting the rotation speed of the fan motor. For example, when the user selects a target gear by touching, the range hood adjusts the rotation speed of the fan motor to a target value according to the gear selected by the user.
And step 103, acquiring environment detection parameters of the range hood.
In the step, the environment detection parameters of the range hood detected by a sensing technology or other technologies are obtained, wherein the environment detection parameters comprise one or a combination of a plurality of wind pressure detection parameters, smoke detection parameters and gas stove operation parameters. Specifically, the pressure detection device can be used for acquiring wind pressure detection parameters reflecting the exhaust pressure of the range hood, the infrared technology can be used for acquiring smoke detection parameters of the environment where the range hood is located, and the gas stove operation parameters and the like can be acquired through the gas stove linkage technology, so that data for analyzing the cooking environment and/or the exhaust environment of the range hood can be acquired.
And 104, generating automatic control information according to the environment detection parameters.
In this step, the automatic control information generated from the environment detection parameter is data having the same structure as the user control information. Taking an example of a method for generating automatic control information by using wind pressure detection parameters, referring to fig. 2, a pressure value and a gear value (may also be a specific motor rotation speed value) have a corresponding relationship as shown by a curve, wherein the motor may adopt an electrodeless direct current motor or the like to realize an electrodeless regulation effect. Of course, other functional relationships may be employed to correspondingly generate the automatic control information.
And 105, controlling the fan of the range hood to run according to the automatic control information and the user control information.
In this step, the automatic control information and the user control information are compared, and since the two data structures are the same, the difference between the two data structures, such as the gear difference and the generated time difference, can be determined by simple condition analysis. Specifically, according to the comparison result that the gear of the user control information and the gear of the automatic control information have large differences, the user may wish to operate with small air volume (such as wish to reduce noise) is analyzed, and then the control is still performed with the user control information; or analyzing that the user may walk according to a comparison result that the generation time of the automatic control information is longer than the generation time of the user control information, and further controlling by adopting an automatic control method, namely controlling in real time by using the automatic control information.
According to the control method of the range hood, the user control information is generated according to the control instruction of the user; controlling the fan of the range hood to run according to the user control information; acquiring environment detection parameters of the range hood; generating automatic control information according to the environment detection parameters; and controlling the fan of the range hood to run according to the automatic control information and the user control information. Therefore, the control method of the range hood can generate the user control information according to the control instruction of the user, generate the automatic control information according to the environment detection parameters, and compare the information with the same two data structures to obtain the user experience of intelligently controlling the operation of the fan of the range hood.

And 203, controlling the display of the gear lamp according to the user control information.
In this step, the control instruction of the user may be displayed with the target gear information via the gear lamp. In specific operation, a touch control slide bar can be arranged in a control panel of the range hood, and a gear lamp is arranged behind the slide bar, and the display of the gear lamp corresponds to a target gear set by a user one by one.
Step 204, acquiring environment detection parameters of the range hood; the environment detection parameters comprise a first environment detection parameter and a second environment detection parameter, and the detection time of the first environment detection parameter is earlier than the generation time of the user control information.
In this step, the obtained environmental detection parameter may be data detected by the range hood in a period of time, or even the environmental detection parameter may be stored, and the controller extracts real-time data and data at a specific time at any time, so as to facilitate analysis and comparison.
Step 205, generating first automatic control information according to the first environment detection parameter.
In this step, first automatic control information is generated based on detecting a preceding first environment detection parameter.
And step 206, generating second automatic control information according to the second environment detection parameters.
In this step, second automatic control information is generated based on the second environment detection parameter detected in real time. Here, the detection time of the real-time detected second environment detection parameter is a generation time of the user control information.
Step 207, determining whether an absolute value of a difference value between the fan control data of the user control information and the second automatic control information is greater than a first threshold.
In this step, the difference value of the fan control data of the user control information and the second automatic control information may be specifically the rotation speed data of the fan motor, and when the absolute value of the difference value of the two is greater than the first threshold value, the user may have a wish of manual control. The first threshold may be set according to user habits or the like.
Step 208, if yes, judging whether the absolute value of the difference value between the fan control data of the second automatic control information and the first automatic control information is smaller than a second threshold value; step 210 or 211 is entered.
In this step, when the absolute value of the difference between the fan control data of the second automatic control information and the user control information is greater than the first threshold, it is indicated that the user may wish to manually control, and at this time, the difference between the fan control data of the second automatic control information and the fan control data of the first automatic control information is further determined.
Step 209, if not, controlling the operation of the fan according to the second automatic control information; step 212 is entered.
In this step, when the absolute value of the difference between the fan control data of the user control information and the second automatic control information is not greater than the first threshold value, it is indicated that the user's intention of manual control is small, and the automatic control method is selected.
Step 210, if yes, controlling the fan of the range hood to operate according to the user control information; step 212 is entered.
In this step, when the absolute value of the difference between the fan control data of the second automatic control information and the first automatic control information is smaller than the second threshold, the pressure change is smaller, and the two judgment results are combined, so that the user can judge that the intention of correcting the automatic control result is stronger, and then the fan operation is continuously controlled according to the user control information.
Step 211, if not, controlling the operation of the fan according to the second automatic control information; step 212 is entered.
In this step, when the absolute value of the difference between the fan control data of the second automatic control information and the first automatic control information is not smaller than the second threshold, indicating that the pressure change is large, and integrating the two judgment results, if it is unable to judge the willingness of the user to correct the automatic control result, controlling the operation of the fan according to the second automatic control information
And 212, controlling the display of the gear lamp according to the running condition of the fan.
In this step, according to the demonstration of the real-time operation condition control gear lamp of fan, can play the effect of linkage, from this, same gear lamp both plays the effect that reflects the manual regulation condition of user, also plays the effect that reflects the fan operation condition, facilitates for the user uses, and then has promoted user experience.
