Now the control interface generally adopts a touch screen structure.

At present, in order to meet the needs of users for touch screen products, the high-end ovens on the market generally use conductive foam, PCB copper skin, springs, etc. to realize touch control. Recently, TFT screen touch is also used in oven products. This control interface has the following disadvantages:

1. The scheme of using conductive foam, PCB copper skin, and spring to realize the touch control of individual buttons. Generally, the user can only adjust the time, temperature and other values by pressing the plus and minus buttons, and the operation is relatively simple and tedious.

2. It is only suitable for the situation that the arrangement of keys has sufficient spacing, and it cannot be realized for the arrangement of keys with a relatively short distance and circular touch.

3. Adopt the touch solution of conductive foam, PCB copper skin, and spring. If you want to realize the scheme of button display and light emission, you have to hollow out the foam or PCB copper skin and place LED lights. The position requirements are relatively accurate, and the defect rate is the highest. If it is not high enough, the sensitivity and reliability will also be affected to a certain extent, and the light emission in the button area is uneven, difficult to control, and also affects the overall appearance.

4. The cost of TFT smart touch is expensive, which is a waste for users. At the same time, we also launched an oven with APP-side smart control function, which allows users to control it remotely and brings unlimited benefits to users. At present, most products provide one-click menus on the local side: such as grilled fish, barbecue, etc., users who do not know how to use them are often at a loss.

5. The various states of the interactive interface of existing products are basically interacted by voice prompts, and there are few visual and tactile interactions.
