Abstract
The utility model discloses a motor soft starter provided with a combined keyboard. The motor soft starter comprises a casing, the keyboard arranged on the casing, a trigger circuit and a central processing unit, and is characterized in that the keyboard comprises a plurality of press keys, wherein each press key can send function signals to the central processing unit independently or after combined with other press keys, and the central processing unit controls the trigger circuit to execute corresponding functions according to the function signals. The motor soft starter provided with the combined keyboard adopts the plurality of finite press keys, various functions are achieved in a combined manner, so that the condition that one function is realized by one press key and a plurality of functions are realized by a plurality of press keys in the prior art is prevented, the area occupied by the press keys is greatly saved, and the defect of overlarge size of the starter is overcome; and besides, a protective cover structure is improved, so that the protective cover can be maintained in an opening state automatically after being opened, and an operator is prevented from single-hand operation.
Description
Technical field
The utility model relates to a kind of motor soft starter, especially the motor soft starter with integral keyboard.
Background technology
Motor soft starter is to adopt Power Electronic Technique, microprocessing and modern control theory and design the Novel starting equipment with current international most advanced level of production.This product is starting current when limiting AC asynchronous motor starting effectively, can be widely used in blower fan, water pump, conveying class and compressor even load, is the desirable regeneration product of the decompression devices such as traditional star/triangle conversion, self-coupling voltage reducing, magnetic control step-down.Along with the continuous progress of technology, the function of motor soft starter also gets more and more, becomes increasingly complex.Therefore, motor soft starter all can be provided with corresponding function key mostly, selects to carry out the various functions such as start and stop, control, communication.Function key is more, and its occupied space is also larger, and this makes the volume of motor soft starter also need corresponding increase.And the increase of volume not only can cause cost to rise, its installing space needing also will increase, and causes it to adapt to occasion and reduces.How addressing the above problem, avoid causing because of the increase of function key the increase of motor soft starter volume, is current problem demanding prompt solution.In addition, in order to protect keyboard, conventionally also can on keyboard, increase a transparent or semitransparent lid, be conventionally need to open lid, and prop up lid with a hand and avoid lid again, another manual manipulation at operation keyboard.This makes the operator can only one-handed performance, very inconvenient, is also one of current problem demanding prompt solution.
Summary of the invention
In order to overcome the problems referred to above, the utility model provides that a kind of button is few, volume is little, the motor soft starter with integral keyboard of handled easily.
The technical solution of the utility model is to provide a kind of motor soft starter with integral keyboard, it comprises shell, is arranged on keyboard, trigger circuit and central processing unit on described shell, it is characterized in that: described keyboard comprises multiple buttons, wherein each button separately or with other key combination after can, to described central processing unit sending function signal, carry out corresponding function by described central processing unit according to trigger circuit described in this function signal control.
Preferably, described button comprises four or six letter keys.
Preferably, described button comprises that 0 to 9 is total to 10 numeric keys.
Preferably, it also comprises a display screen, for showing the key value of described keyboard input.
Preferably, described button also comprises input error corrigendum key.
Preferably, described button also comprises execute key.
The over cap of the described keyboard of one protection preferably, is also set on described shell.
Preferably; described over cap comprises lid, and a side of described lid is provided with the feet of two protrusions, and described in two, the outside of feet respectively arranges a protrusion lug; two strip through holes are set on described shell, and two feets are arranged on described lid through described through hole.
Preferably, described in two on the sidewall of through hole all the direction along vertical described shell be provided with at least one fin.
Motor soft starter with integral keyboard of the present utility model adopts several limited buttons, mode by combination realizes several functions, thereby a button before having avoided is realized a function, multiple functions need the situation of multiple buttons, greatly save the area that button takies, avoided the excessive shortcoming of starter volume.In addition, can improve the structure of over cap, make it can after opening, be stabilized in voluntarily open mode, thereby avoid the situation of operator's one-handed performance.
Accompanying drawing explanation
Fig. 1 is the perspective view of a kind of motor soft starter with integral keyboard of the utility model most preferred embodiment;
Fig. 2 is the front elevation of over cap;
Fig. 3 is the principle schematic of over cap and shell.
Embodiment
Below embodiment of the present utility model is described in further detail.
As shown in Figure 1 to Figure 3, a kind of motor soft starter with integral keyboard 12 of the present utility model comprises shell 10, is arranged on keyboard 12, trigger circuit (not shown) and central processing unit (not shown) on shell 10 front surfaces.Keyboard 12 comprises multiple buttons 14, and all button 14 is arranged in square.Button 14 can comprise four or six letter keys or 0 to 9 10 numeric keys altogether.Also comprise that input error corrigendum key 16, button 14 also comprise execute key 18.Wherein each letter key/numerical key produces a function signal separately or after combining with other buttons 14, user presses after execute key 18, send this function signal to central processing unit, carry out corresponding function by central processing unit according to this function signal control triggering electric circuit.If input error, the button 14 that can eliminate just input by error correction key 16 is worth.For example, comprise A, B, C, tetra-alphabet keys 14 of D.User presses B after pressing A, inputs the function signal of an AB, and this signal is translated into corresponding function by central processing unit, thereby carries out this function.Like this, 4 buttons 14 can be realized 24 kinds of two alphabetical combinations, thereby realize 24 kinds of functions, have effectively avoided needing the situation of 24 function buttons 14, very convenient and practical, also easily memory.
Further, it also comprises a display screen 20, the key value of inputting for display keyboard 12.
The over cap 22 of one protection keyboard 12 is also set on shell 10 further.This over cap 22 comprises lid 24, and the outside that a side of lid 24 is provided with feet 26, two feets 26 of two protrusions respectively arranges a protrusion lug 28.Two strip through hole 30, two feets 26 are set on the surface of shell 10 and are arranged on lid 24 through through hole 30, and pass through lug 28 inlay cards in through hole 30, avoid lid 24 to drop.On the sidewall of two through hole 30, be all provided with at least one fin 32 along the direction of vertical enclosure 10.When motor soft starter vertically arranges, when lid 24 upwards turn to level, lug 28 turn to the below of fin 32 downwards.Unclamp lid 24, when lid 24 overturns downwards under Action of Gravity Field, fin 32 just in time stops lug 28, thereby avoids lid 24 to continue upset downwards, covers in keyboard 12.After user's input, apply a little certain strength, can make lug 28 cross fin 32, lid 24 overturns downwards, covers keyboard 12.
Above embodiment is only the utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
