a control device

Abstract

The invention discloses a control device. The control device comprises a circuit substrate capable of being electrically connected with equipment to be controlled, a rotating shaft arranged on the circuit substrate, and a rotary disc sleeving the rotating shaft, and the circuit substrate is provided with two concentric conductive circular rings; the rotary disc rotates in a mode of using the two concentric conductive circular rings as lead rails; the rotary disc is provided with one or more key modules capable of always electrically connecting with the two conductive circular rings in the rotating process of the rotary disc and provided with a key switch, and the control device further comprises a key switch circuit capable of performing input control through the key switch of the key module. According to the control device, one or more key modules can be arranged on the rotary disc, the rotary disc can use circular ring shape, a display screen can be placed in the hollow position, and the structure is simple, compact and beautiful.

Description

technical field [0001] The invention relates to a control device, in particular to a control device with a rotating disc. Background technique [0002] With the development of technology, the functions of electrical appliances, such as household appliances, or electronic products are increasing, and the increase in functions correspondingly leads to an increase in control, such as the discreteness of various modes, cycles, states, options and / or parameters of the equipment. choose. Knob control is a common control method at present. Generally, the cycle, status, options and / or parameters are changed through the knob. However, when selecting, confirming, canceling or switching various modes, it is often necessary to set buttons independently outside the knob. Therefore, when the functions of the equipment increase, the control device also becomes complicated accordingly. Moreover, when the user turns the knob to the input parameter he wants, he often needs to break away fro...

Problems solved by technology

[0003] In addition, there is often a display interface in the control of household appliances, such as a display screen, which is often matched with the knob in function, for example, the display shows parameters, and after the parameters are changed by rotating the knob, the display displays the changed parameters in real time; However, the two structures are independent of each other and installed separately, which makes the control devices of household appliances look messy and complicated, not simple and compact enough, especially when the functions of household appliances increase, and the number of inputs and controls increases, this defect becomes more and more obvious, which greatly Affects the aesthetics of electrical appliances
