Description
Technical field
The present invention relates to the control device of a kind of micro-wave oven, particularly a kind of micro-wave oven.
Background technology
At present, the control device of existing micro-wave oven has following several: mechanical type, button electronic type, thin film switch formula etc.Wherein: the space that mechanical type and button electronic control device occupy is bigger, and not high to the regulation and control sensitivity of time and temperature, the market of more and more fading out; Thin film switch formula control device has solved the relevant issues of mechanical type and button electronic type.Thin film switch formula control device comprises upper film layer, following paper rete, control box and computer plate, and paper rete correspondence was provided with copper sheet up and down under the upper film layer reached, and the following copper sheet of following paper rete is connected with golden finger, and golden finger is connected with the computer plate.When removing to push the upper film layer with hand, the last copper sheet on the last thin layer just moves inward and the following copper sheet of following paper rete contacts, and information passes to the computer plate by golden finger, thereby the computer plate sends corresponding indication, and micro-wave oven is started working.The defective of this technical scheme is: each operation must be exerted oneself presses the upper film layer, of long duration, can make that copper sheet follows the string up and down, and information is transmitted not accurate enough, thereby has influenced the life-span of whole control device.
Chinese patent literature CN1715775 discloses a kind of Control Component of micro-wave oven, includes: constitute the control panel that is formed with perforate on outward appearance and the leading flank; Be fixedly mounted on the circuit substrate of control panel inboard, be set with the display part that stretches out to the outside by the perforate of control panel on the circuit substrate, also include: the cut-out hole that can pass circuit lead that is provided with on the control panel; Attached to the button on the lateral surface of control panel portion is set; Its button is provided with portion and is provided with transparent structure at the formation position corresponding to the perforate of control panel, and button is provided with and also is provided with various operated keys in the portion, and the lead of the cut-out hole of its operated key by connecting control panel is connected with the circuit on the circuit substrate; Perspective window with thickness also is set between the transparent position that the perforate position and the button of control panel is provided with portion.It is said that this technical scheme has low cost of manufacture, avoided because the not cleer and peaceful button because of support member of display part identification that various pollutions cause is bad to being discontented with that the consumer brings.But the Control Component of this micro-wave oven is a button still, has above-mentioned defective.
Therefore, be necessary to design the control device that a kind of brand-new micro-wave oven is used, to satisfy the demand day by day in market.
Summary of the invention
Purpose of the present invention aim to provide a kind of simple and reasonable, easy to operate easily, the control device of the micro-wave oven of long service life, touch-induction-type, to overcome weak point of the prior art.
Press the control device of a kind of micro-wave oven of this purpose design, comprise that the surface is provided with the control panel of window, the control panel inboard is provided with display panel module, and display screen is protruding from the window on the control panel, and its architectural feature is also to be provided with the sensor key Control Component on the control panel.
Described sensor key Control Component comprises touch-screen and capacitive sensing module, and touch-screen is arranged on the control panel outside, its surface be provided with some menu mark and with the corresponding window of display screen size; Be provided with the capacitive sensing module between touch-screen and control panel, its surface is provided with and the corresponding induction zone of touch-screen menus mark; Medial surface is provided with acquisition processing module below display screen, and it and capacitive sensing module electrically connect.
Described sensor key Control Component also comprises navigation module backlight, and navigation module backlight is arranged between control panel and the display panel module; Be provided with driver module between navigation module backlight and acquisition processing module, acquisition processing module drives navigation module work backlight by driver module.
When staff near or when touching touch-screen, by the induction of the capacitance between finger and the capacitive sensing district, the capacitive sensing module is obtained the menu information on the touch-screen automatically, and be converted into and pass to acquisition processing module for the information of acquisition processing module identification, acquisition processing module according to the information of its storage inside, sends corresponding operational order to micro-wave oven again.
At prior art, the present invention is by the capacitive sensing information between finger and the capacitive sensing module, and the transmission between the solicited message makes micro-wave oven carry out relevant operation.User's only with hand is depended on the menu mark near or the outer field touch-screen of touch control device, just can operate micro-wave oven, and is simple to operation.Simultaneously, in use, can the wear control device, thereby prolong service life of control device; In addition, its space that occupies is also less relatively; Because the existence of navigation feature backlight, can avoid the user error operation and accidents caused, the corresponding raising of safety in utilization.
