Problems solved by technology

The difference in the use environment will cause the same model of range hood to have different motor speeds in different use environments under the same gear.
In addition, due to various errors in the manufacturing process, there will also be a deviation between the actual speed of the range hood in a certain gear and the standard speed corresponding to the current gear.

Embodiment 1

[0031] The present invention proposes an embodiment of a range hood, which includes a motor, an impeller, a control device, a gear selection switch, a user operation device, a display device, and a speed detection device. The control device is used to control the speed of the motor, and the motor is used to drive the The impeller rotates. The gear selection switch, the user operation device, the display device and the rotational speed detection device are all connected to the control device respectively.

[0032] The gear selection switch is used for the user to select a gear, and sends information about the gear selected by the user to the control device. The control device is used for controlling the motor to run at the gear after receiving the gear information selected by the user. As far as this embodiment is concerned, the gear selector switch is provided with three gears: low gear, middle gear and high gear. If the user selects the middle gear, the control device contro...

Embodiment 2

[0038] The present invention also proposes another range hood embodiment, which includes a motor, an impeller, a display device, a rotation speed setting device and a control device. The control device is used to control the speed of the motor, and the motor is used to drive the impeller to rotate. The speed setting device is connected to the control device. The speed setting device is used for the user to set the motor speed, and sends the user-set motor speed to the control device; the control device is also used for controlling the motor at the set speed after receiving the set motor speed. run at motor speed.

[0039] The range hood is also provided with a rotational speed detection device for detecting the actual rotational speed of the motor and sending the actual rotational speed to the control device. The control device is also used to compare the actual speed and the set motor speed. If the actual speed is different from the set motor speed, adjust the motor speed u...

Abstract

The invention provides a range hood and a control method thereof. The range hood proposed by the present invention includes a motor and a control device, the control device is used to control the rotation speed of the motor, and a rotation speed detection device is used to detect the actual rotation speed of the motor in the current gear, and the The actual speed is sent to the control device; the standard speed of the motor corresponding to each gear is stored in the control device; the control device is also used to compare the received actual speed with the corresponding speed of the current gear. Standard rotational speed, if the actual rotational speed is less than the corresponding standard rotational speed, the rotational speed of the motor is increased; if the actual rotational speed is greater than the corresponding standard rotational speed, the rotational speed of the motor is decreased. In this way, the speed of the motor is adjusted according to the difference between the actual speed and the standard speed corresponding to the current gear, which can overcome the influence of the specific use environment or manufacturing errors on the actual speed of the range hood motor to a certain extent. .

Description

【Technical field】 [0001] The invention relates to the field of range hoods. 【Background technique】 [0002] Range hood, also known as range hood, is a kitchen appliance that purifies the kitchen environment. It is installed on the top of the stove in the kitchen, which can quickly remove the oily fumes harmful to the human body produced during the cooking process, purify the indoor air, and have the safety guarantee function of anti-virus and explosion-proof. [0003] The specific use environment of range hoods is very different, such as the difference in the length of the exhaust pipe, the difference in the public flue, and the difference in the cleaning of the filter screen. The difference in the use environment will cause the same type of range hood to have different speeds of the corresponding motors in different use environments under the same gear. In addition, due to various errors in the manufacturing process, there will also be a deviation between the actual speed...
