Abstract
The utility model discloses a touch keystroke control structure of a floor type air conditioner, which comprises a human-computer interaction keystroke touch casing. A touch key display area is arranged on the front surface of the touch casing, and a touch induction circuit board is arranged on the back surface of the touch casing. The touch casing is made of organic glass. The size of the induction area of a touch keystroke circuit board is corresponding to the size of a touch keystroke on the touch casing. The touch circuit board is connected with a main control circuit board by a signal wire. The utility model cancels a mechanical type connection mode, and is not influenced by the ageing and the loose of a structural member. Thus, the reliability of the touch keystroke control structure is raised and the cost is reduced. The touch keystroke control structure provided by the utility model can also be used for other products with keystroke control apparatuses.
Description
Technical field
The utility model relates to air conditioner control mode technical field, is specifically related to a kind of split-floor type air conditioner touch key-press control structure.
Background technology
Along with the progress of society, the use of various electric equipment products also more and more widely, the use of electrical equipment all realizes by the human-computer interaction device.The mode of manipulating of existing electrical equipment can be divided into two kinds, and a kind of be the mode of operation of Full remote controlled, and another kind of is that remote controller is operated and the comprehensive mode of manual operation, also have minority be only be with manually operated.Wherein the mode of operation of manual type comprises following two kinds of schemes:
1, touch-switch button, what mainly use is mechanical button, by keyboard mechanical parts conduction, produces the input that change in voltage is finished control signal.
2, direct charge inductive type button utilizes human body self institute static electrification, by conduction button conduct charges, and utilizes the variation of the electric charge induction circuit inductance quantity of electric charge, finishes the input of control signal.
Yet above-mentioned two kinds of schemes all in various degree exist defective: for light touch switch type key, it is mainly realized by mechanical connecting structure, repeatedly use be easy to generate aging, wearing and tearing, situations such as loose contact; And be subjected to the restriction of structural member easily, because the connection that mechanical button polygamy closes structural member is operated, unreasonable when structural member, when not firm, processing ease lost efficacy; And,, being easy to generate misoperation because electric charge directly is sent on the electromagnetic induction circuit by the conduction key component for the charge inductive type button, reliability is not high.
China's ZL200420047169.4 patent " a kind of touch control induction circuit that is used for electromagnetic oven " touch control induction circuit that provides, when finger touches the sensing chip induction region, the electric capacity that forms between sensing chip and finger will make the voltage of the output of integration output circuit change, this changes after amplifying circuit amplifies, carry out sampling processing by MCU, realization is identified as key information with the finger touch induction of signal, and then realize the operation of electromagnetic oven is controlled, the sensor circuit that this utility model provided, the structure relative complex is not suitable for the control mode of air-conditioning yet.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, split-floor type air conditioner touch key-press control structure that reliability is high.
The utility model is achieved through the following technical solutions:
Design a kind of floor type air-conditioner touch key-press control structure, comprise that the button of man-machine interaction touches housing, the front that the irritability insulating matter touches housing is provided with the touch key-press viewing area, and the back side that touches housing is provided with the touch induction circuit plate.
Described touch housing adopts irritability good insulation toughened glass to process, the induction zone position of touch key-press circuit board is corresponding with the position, touch key-press viewing area that touches the housing front, and described touch circuit board is connected with main control board by holding wire.
The utility model has following remarkable result compared with prior art:
Touch housing in the utility model and adopt toughened glass to make, in appropriate circumstances, touch housing and can adopt other sensitivities material preferably; Owing to cancelled mechanical connected mode, be not subjected to aging and unstable influence of structural member, make the reliability of this control mode improve greatly, reduced the cost that exploitation is made; Touch key-press control structure provided by the utility model also can be applied to other bands and use by on the key control household electronic products.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the sensor circuit principle schematic.
Embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
Referring to Fig. 1～2, a kind of touch key-press control structure of floor type air-conditioner, the button that includes man-machine interaction touches housing 1, touches housing and adopts the toughened glass processing and fabricating, and case material also can adopt other sensitivity good insulation materials processings to make.Housing front 2 is provided with touch key-press viewing area 21, sets the sign of eye-catching keypress function on the viewing area, is convenient to the person's of manipulating identification.Requiring to make the key induced circuit board of setting on the touch back side of shell 3 and the size of induction zone thereof according to button size, spacing etc.Key induced circuit board is fixed on the back side of toughened glass housing with the glue of solidity, and is close to this face.
The sensor circuit plate that is provided with on this touch back side of shell is connected with master control circuit board by holding wire.Key induced circuit board responds actuation of keys, and actuation of keys is converted to the signal of telecommunication, sends the master control chip to, and master chip feeds back the control corresponding action then by judging the validity of push button signalling.
This electromagnetic induction circuit theory is to utilize the self-oscillation of the LC electromagnetism oscillating circuit of inductance L 1, capacitor C 3 and operational amplifier U1 composition, produces Motionless electromagnetic concussion frequency.Because the setting in keypress function district, housing front 21 is that the setting with the electric charge induction district 4 of housing reverse side is corresponding, so when the people touches the touch key-press functional areas 21 of the positive setting of housing, human body self the electrically charged induction zone 4 that just touches oscillating circuit, owing to the effect of electric charge, can change the fixed frequency of the electromagnetism concussion of this circuit.Circuit is judged the input of button control action, thereby is finished the corresponding operating function by detecting the variation of electromagnetism concussion frequency.
Touch key-press control structure provided by the utility model does not have the mechanical type connected mode, is not subjected to aging and unstable influence of structural member, makes the reliability of this control mode improve greatly, has reduced the cost that exploitation is made; Touch key-press control structure provided by the utility model also can be applied to other bands and use by on the key control household electronic products.
