Detailed Description

The invention will be further elucidated with reference to the drawings in which:

referring to fig. 1, a touch panel assembly 1 includes a touch panel 11, at least one touch key 10 disposed on the touch panel 11, and a controller, where the touch key 10 is connected to the controller, a range hood function unit is connected to the touch key 10 through the controller, one of the touch keys 10 can send a lock/unlock signal to the controller, and the controller receives the lock/unlock signal and controls the range hood function unit to fail/be effective according to the lock/unlock signal; the range hood functional unit can also execute a functional instruction from one of the touch keys 10. Preferably, the functional instruction may be an instruction closely related to the operating state of the range hood functional unit, such as a fan operation instruction, a lighting lamp illumination instruction, and the like. Preferably, one of the touch keys can both lock/unlock the range hood functional unit through the controller and control the range hood functional unit to execute a function instruction input by a user from the touch key through the controller. The structural design can not separately set the 'main switch' with only a single locking/unlocking function, but the single 'main switch function' is combined on the touch keys for executing the functional instructions, so that the layout design of the touch keys on the touch panel is more reasonable, and the product intelligence degree is higher. Preferably, the touch panel assembly is wholly or partially arranged in the mounting box and is mounted on the panel of the range hood through a mounting hole in the mounting box. Preferably, the type of the touch key may be a touch type push switch, a touch screen switch, or the like.

Referring to fig. 2, when the range hood functional unit is in a disabled/valid state, the range hood functional unit does not execute/execute the function command from the touch key.

Referring to fig. 3, the controller is integrated on the touch panel 11, the touch keys 10 are connected with the controller through a circuit on the printed circuit board, and the controller is connected with the range hood functional unit through a control circuit.

Referring to fig. 3, the touch key 10 includes a touch sheet soldered to a printed circuit board through a spring. Preferably, the touch key is a light touch type press switch.

Referring to fig. 1, the range hood further includes a display 12, the display 12 is disposed on the touch panel 11, and the display 12 is used for displaying a state of the range hood functional unit. Preferably, the display 12 can display the disabled/enabled state of the range hood functional unit, or the specific working state of the range hood functional unit in the enabled state, such as the running state of the fan, the lighting state of the lighting lamp, etc. Preferably, the display 10 may employ indicator lights, LED/LCD display screens, touch screens, or the like. Preferably, the display 12 is connected with a controller, and the controller can collect the state of the range hood functional unit and feed the state back to the display 12 for display.

A touch panel cleaning locking judgment method uses the touch panel assembly 1.

Referring to fig. 4, at least two touch keys 10 are disposed on the touch panel 11, the touch keys 10 respectively generate a signal corresponding to each touch key 10 after receiving a touch from a user, the controller determines whether the signal is a false operation according to a time difference of the signal corresponding to each touch key 10, if the time difference of the signal does not exceed a preset time threshold, the controller determines that the false operation is performed, and the controller controls the range hood functional unit to be in a failure state; if the signal time difference exceeds the preset time threshold, the operation is determined to be valid, and the controller receives the signal sent by the touch key 10 and executes the instruction corresponding to the signal. Specifically, if the range hood functional unit is in a failure/valid state and a user has a misoperation, the controller controls the range hood functional unit to be in the failure state, for example, when the user cleans the touch panel 11, since the time difference of the scrubbing action to quickly touch the at least two touch keys 10 is less than a predetermined time threshold, preferably, the predetermined time threshold is set to 1 s. If the functional unit of the range hood is in a failure state and the user effectively operates, the controller controls the functional unit of the range hood to receive the unlocking signal sent by the touch key 10 to execute the unlocking instruction and then execute the functional instruction. If the range hood functional unit is in an effective state and the user performs effective operation, the controller controls the range hood functional unit to receive the functional signal sent by the touch key 10 and execute the functional instruction or receive the locking instruction to enable the range hood functional unit to be in an invalid state. Preferably, at least two touch keys 10 may have a touch key capable of sending a lock/unlock signal, or may not have a touch key capable of sending a lock/unlock signal.

Referring to fig. 2, after a user inputs a locking/unlocking instruction to the touch key 10 capable of sending a locking/unlocking signal, the touch key 10 sends the locking/unlocking signal to the controller, and the controller controls the range hood function unit to be in a disabled/valid state according to the locking/unlocking signal.

Referring to fig. 2, when the range hood functional unit is in a disabled/valid state, the range hood functional unit does not execute/execute the function command from the touch key 10.

A range hood uses the touch panel assembly 1, and when a touch panel 11 is cleaned, the functional unit of the range hood is in a failure state by adopting the touch panel cleaning locking judgment method.
