Because what soft-touch control 15 detected is that staff touches staff static capacity timely, can eliminate the misoperation that causes because of the static capacity beyond the staff.
Soft-touch control 15 is located at the opposite side relative with pivot, that is is provided with by pivot 14 and carries out free end one side in the refrigerating chamber gate 11 of rotatable supporting.
In addition, soft-touch control 15 usefulness constitute with surface members that forms refrigerating chamber gate 11 that is the different miscellaneous part of gate plane materiel 11a.And soft-touch control 15 is arranged to vertically long shape on the gate short transverse, and soft-touch control 15 is separated mutually on left and right directions with gate plane materiel 11a.
In addition, soft-touch control 15 is arranged on the shell 17 that constitutes decorative panel, and shell 17 is arranged to protrude about about 1～2mm towards the place ahead than gate plane materiel 11a.
As shown in Figure 3, be provided with in the soft-touch control 15: by user's the resin enclosure that hand touched 17; With printed circuit board (PCB) 19 rear that is located at shell 17, that have conductivity inductive means 18.
Parts on the substrate 19 are provided with shown in situation such as Fig. 2 and Fig. 3.The top of printed circuit board (PCB) 19 is provided with display unit 16, and the bottom is provided with from top to bottom successively: thus be used for setting temperature of refrigerating chamber refrigerating chamber soft-touch control 15a, be used to set the vegetable compartment temperature vegetable compartment soft-touch control 15b, be used to set freezer temperature refrigerating chamber soft-touch control 15c, make quick-frozen soft-touch control 15d that refrigerating chamber cools off fast, ozone soft-touch control 15e that the ozone of emitting ormal weight to the vegetables that are collected in vegetable compartment is disposed the agricultural chemicals that attaches on vegetables, thereby filter surfaces carried out that rayed produces silver ion to have the OH base (hydroxyl) of bacterial decomposition ability the moving silver-colored soft-touch control 15f of light that through the moving silver of light refrigerating chamber is carried out degerming.
In addition, as shown in Figure 6, the lower surface 18c of inductive means 18 is provided with clamping part 20, is used to sandwich with printed circuit board (PCB) 19 conduct electricity the link 21 that is connected.Through clamping, link 21 is fixed on the inductive means 18 by an inductive means 18 and the part of clamping part 20 with link 21.
Like this, clamp by clamping part 20, not only can keep electric conductivity, can make link 21 on inductive means 18, position easily/support simultaneously, do not produce homework burden, and can reduce the assembling deviation through the end that makes link 21.Therefore, inductive means 18 can be realized support/fixation in intimate contact with link 21, and the deviation that assembling process produces can be reduced, and reliability also can be improved.
Clamping part 20 is through constituting cocked 20 of the incision that the part of inductive means 18 is cut, cocked back forms.
Specifically, inductive means 18 is processed by metal material, as shown in Figure 6; Its upper surface 18a is roughly planar portions, and the two ends of upper surface 18a are bending and inflection towards the below, forms reflex part 18b; The two ends of reflex part 18b are cut open again/and cocked, form and cut cocked 20.
The forming process of reflex part 18b is earlier upper surface 18a roughly to be bent into right angle orientation towards the below, and then roughly to turn back towards horizontal direction.
And a part in the link 21 is crossed over cocked 20 of the incision that be located on the both sides, thereby supported, fixing.Like this; Inductive means 18 can be realized the tight mutually supporting that contacts, fixing with link 21; Thereby reduce the deviation in the assembling, and because the upper surface 18a of inductive means 18 roughly is planar shaped, which place of soft-touch control 15 no matter the user touch; Can keep very high detection sensitivity, because of the different sensitivity variations that produce of touch location also can obtain reducing.
In addition, the parts of the flexible effect of link 21 apparatus constitute, and are to constitute with spring specifically, and the end of spring 21 is fixed in being clamped into and cutting cocked 20.
In addition; Because link (spring) the 21st is clamped in cutting cocked 20; From the angle of assembling operation, can when positioning, accomplish supporting, the operation error that spring 21 supportings are fixed in the process on the inductive means 18 also can reduce.
In addition, being supported the part of fixing spring 21 and the contact portion of cutting between cocked 20 can also fix through scolding tin 22.So, water enters in the printed circuit board (PCB) 19, cause that contact portion is got rusty/corroded etc., and phenomenon can be prevented, the raising of also attaining the Way of detection sensitivity and reliability.
The other end of spring 21 is fixed by scolding tin after passing printed circuit board (PCB) 19, and the touch operation signal is delivered in the control unit.
Below to be positioned at around the inductive means 18, the structure that is provided with of luminous light-emitting diode 23 was described when inductive means 18 detected static capacity.
As shown in Figure 5, inductive means 18 is provided with a plurality of, and 15a～15f is corresponding with soft-touch control, is provided with by inwall 24a and outer wall 24b box body 24 that constitute, that be double-layer structural around each inductive means 18.Box body 24 is fixed on the printed circuit board (PCB) 19.
As shown in Figure 6, be provided with light-emitting diode 23 in the spatial portion 25 that between inwall 24a and outer wall 24b, forms, inductive means 18 is arranged on the inwall 24a.
The substrate 26 that is the level of state is installed in the spatial portion 25, and light-emitting diode 23 is set up/is fixed on the substrate 26.
That is to say; Light-emitting diode 23 is installed into towards vertical direction; And the luminous intensity of light-emitting diode 23 has directivity, so the briliancy of the upper surface direction of directive box body 24 is stronger, and a little less than the luminance ratio upper surface direction of directive inwall 24a, outer wall 24b side wants.
And the inwall 24a and the outer wall 24b of box body 24 are made into to have color, thereby make the light of light-emitting diode can not be leaked to the outside.The upper wall 24c of box body 24 stops up the upper surface of spatial portion 25 live, and this upper wall 24c shape that is translucent makes the light of light-emitting diode 23 can be to outdiffusion.
Like this, the light of light-emitting diode 23 can evenly see through upper wall 24c.In addition, also can install a plurality of light-emitting diodes 23 on the substrate 26, can further improve like this from the uniformity coefficient of the light of translucent upper wall 24c ejaculation.
In addition; At inductive means 18 through under spring 21 and the state that printed circuit board (PCB) 19 realizations are connected/fix; Upper surface 18a is positioned at the top of the upper surface 24c of box body 24, and the bottom of inductive means 18 that is reflex part 18b are positioned at the below of the upper surface 24c of box body 24.
After inductive means 18 and box body 24 are fixed on the printed circuit board (PCB) 19 according to above-mentioned position relation, again printed circuit board (PCB) 19 is fixed on the back side of the shell 17 that the user operates.In the time of fixedly, the upper surface 18a of inductive means 18 is pressed on the back side 17b of shell 17, sees Fig. 7.
Like this, because upper surface 18a always keeps by the state of the elastic compression of spring 21 on the 17b of the back side of shell 17, therefore when the user contacted specific region corresponding on the shell 17, its static capacity just can be detected, thereby keeps very high sensitivity.
In addition; When printed circuit board (PCB) 19 is fixed on 17 last times of shell; As shown in Figure 7; Because the upper surface 18a of inductive means 18 is upper surface 24c than box body 24 slightly to the protruding state in top; That is to say between the upper surface 24c of shell 17 and box body 24 and leave slightly under the situation in some gaps that the upper surface 18a of inductive means 18 is pressed on the shell 17 and fixes, even can guarantee the wilfully poor impaction state that also can not influence between inductive means 18 and the shell 17 of some assembling between shell 17 and the printed circuit board (PCB) 19 like this.
In addition; Because the reflex part 18b in the inductive means 18 is arranged in the below (see figure 6) of the upper surface 24c of box body 24; Therefore; Printed circuit board (PCB) 19 is being fixed to 17 last times of shell, can preventing that inductive means 18 from sliding into the top of the inwall 24a of box body 24, making that printed circuit board (PCB) 19 can't embed, fixing generation less than the situation such as assigned position on the shell 17.
Change sentence and speak, form first bending, the shape of inflection again through making inductive means 18, just can realize the location for box body 24, the quality of assembling operation can be improved.
One end of spring 21 is for being wound into the spiral helicine ring spring 21a of portion, and the other end is the linearity connecting portion 21b that constitutes one with the 21a of ring spring portion.Realize fixing during the top of the 21a of ring spring portion is stuck in and cuts cocked 20, connecting portion 21b is fixed on the printed circuit board (PCB) 19 through scolding tin.
And the scope of activities of ring spring portion 21 is set in the box body 24.Specifically, under the state that is blocked by the protuberance 24d to the inner bulge of box body 24 in the bottom of the 21a of ring spring portion, connecting portion 21b is fixed on the printed circuit board (PCB) 19.
In addition, box body 24 not only makes spring 21 realize the location, goes back the resettlement section that double as is accommodated light-emitting diode 23.
Specifically, the substrate 26 that light-emitting diode 23 is installed also is set on the protuberance 24d of the inboard protrusion of inwall 24a.Therefore, protuberance 24d not only provides the space that is provided with of substrate 26, and through the 21a of ring spring portion is arranged on the location that can also realize spring 21 on the protuberance 24d.
In addition; Inwall 24a through vertically downward bending part in the inductive means 18 being arrived in the box body 24 goes up to limit its scope of activities; Inductive means 18 can reduce with respect to the installation site deviation of box body 24, and the deviation of detection sensitivity also can reduce, and detection sensitivity can improve.
The working condition of the soft-touch control 15 after next, being fixed on the shell 17 to printed circuit board (PCB) 19 is described.
Soft-touch control 15 is set at opposite side relative with pivot on the refrigerating chamber gate 11, is controlled so as to usually under refrigerating chamber gate 11 closing state, to operate.
Specifically; When under refrigerating chamber gate 11 closing state, touching (for example) refrigerating chamber soft-touch control 15a; Be pressed on shell 17 the back side, promptly detect its static capacity with the corresponding inductive means 18 of refrigerating chamber soft-touch control 15a and change; Spring 21 energisings that conducting is connected are delivered to printed circuit board (PCB) 19 with detection signal, make the luminous continuously or flicker of corresponding light-emitting diode 23.The illumination of light-emitting diode 23 is mapped on the translucent upper surface 24c of box body 24, exposes to the outside through transparency window corresponding with upper surface 24c on the shell 17 (not shown in the accompanying drawing) again, demonstrates the operated situation of switch to the user.
Refrigerating chamber design temperature display part in the display unit 16 demonstrates current design temperature usually, touches refrigerating chamber soft-touch control 15a again one time, gets final product so that the design temperature of refrigerating chamber changes.Every touch once can make 1 ℃ of design temperature display change.
That is; With regard to the refrigerating chamber soft-touch control 15c of soft-touch control such as the refrigerating chamber soft-touch control 15a that is used to carry out the temperature setting, the vegetable compartment soft-touch control 15b that sets the vegetable compartment temperature, setting freezer temperature; Primary touch operation shows current design temperature; At the appointed time same soft-touch control is operated, design temperature is changed.
On the other hand, the moving silver-colored soft-touch control 15f of the soft-touch control beyond the temperature setting switch of each storeroom that is quick-frozen soft-touch control 15d, ozone soft-touch control 15e and light then be controlled so as to through the first time touch operation just can change the setting pattern.
In addition, when the soft-touch control of adjacency has input simultaneously, then make both sides' input invalid and make corresponding light-emitting diode 23 non-luminous controls, can prevent misoperation like this.
In addition, the soft-touch control 15 that carries out aforesaid operations control is arranged on the shell 17, and shell 17 is arranged to protrude towards the place ahead than the gate 11 of refrigerating chamber, so has formed fall-part 17c (see figure 1) on the line of demarcation between shell 17 and the refrigerating chamber gate 11.
In addition, as shown in Figure 8, under the situation that user under refrigerating chamber gate 11 closing state cleans with rag etc., rag might touch a plurality of soft-touch controls 15 simultaneously at clean operation.When touching adjacent refrigerating chamber soft-touch control 15a and vegetable compartment soft-touch control 15b at the same time; Be not that whole inputs with both sides' soft- touch control 15a, 15b are all as invalid; But the input of switching signal that will at first touched, it is invalid that the switching signal that second quilt touched is regarded as.That is, sliding under the situation of bottom on the top of rag from shell 17, the signal of refrigerating chamber soft-touch control 15a is transfused to, and the signal of vegetable compartment soft-touch control 15b is then made invalidation.
Under these circumstances; Because refrigerating chamber soft-touch control 15a belongs to be used to carry out the soft-touch control that temperature is set; Even rags etc. produce the input operation of violating user view; Under initial input state, also just demonstrate current temperature and set situation, the wish that can not violate the user changes the design temperature in the storehouse.
Carry out under the situation of wiping/cleaning with the refrigerating chamber gate 11 of rag the user refrigerator top; Owing to be formed with fall-part 17c between refrigerating chamber gate face 11 and the shell 17, thereby can induce the user that refrigerating chamber gate face 11 and shell 17 are carried out wiping respectively consciously.And as shown in Figure 8, user's wiping operation generally wipes rag from the top down.Violate the current setting pattern that user's wish changes soft-touch control 15 in order to prevent such operation that wipes; Display unit 16 is arranged on topmost; The below of display unit 16 is above-below direction Horizon row the soft-touch control 15a～15c that is used to carry out the temperature setting is being set, and soft-touch control 15d～15f beyond the temperature setting switch, that be used to carry out the feature operation setting down is set again.Like this, even rag etc. touch adjacent soft-touch control simultaneously, also can reduce the misoperation that causes because of wiped clean.
In addition, when refrigerating chamber gate 11 was opened, gate switch (not shown) can detect open state, and it is invalid that the input of soft-touch control 15 is arranged to.
Like this, even staff touches soft-touch control 15 in the shutoff operation process when closing cold room gate 11, the purpose that can prevent to violate the user carries out that temperature is set and feature operation is set, and improves the effect that prevents misoperation.
In addition; Under refrigerating chamber gate 11 closing state; Can also set for when specific soft-touch control (like the moving silver-colored soft-touch control 15f of light) when pressing continuously at the appointed time then all the operation of soft-touch controls 15 be locked; It is invalid that switching manipulation is become, and can produce the mishandled effect that prevents child like this.
In addition, as shown in Figure 9, the inductive means of soft-touch control also can adopt other structure, as makes the part of metal inductive means 30 play the effect of link 30a, and inductive means 30 is constituted one with link 30a.
Specifically, upper surface 30b still roughly forms flat shape, is pressed in to carry out the face contact on the back side of shell, constitutes induction part, and this is not changed by induction part that upper surface 30b constitutes.But as shown in Figure 10 that kind has formed 4 30a of foot of link effect around the upper surface 30b, and the 30a of each foot is fixed on the substrate 19 after the right angle bending in the below.
And the bottom of the 30a of each foot on top that is positioned at substrate 19 is fixed on the substrate 19 with scolding tin also after formation has the bending part 30c of elastic reaction.
Like this; Because bending part 30c can produce elastic reaction; Can make upper surface 30b be arranged to come in contact while the back side of pushing shell 17, therefore, when user's hand touches the soft-touch control 15 on the shell 17; Can correctly detect the static capacity of staff, the storehouse temperature that can normally accomplish refrigerating chamber etc. is set or the operation of function setting such as quick-frozen.
And, form parts owing to constitute the upper surface 30b of inductive means with the 30a of foot that constitutes link, need not to fix the corrosion of fixed position and get rusty and be easy to prevent that the detection of static capacity is bad also can be reduced through scolding tin etc.In addition, owing to have only parts, manufacturing cost also can reduce.
In sum; Soft-touch control of the present invention is provided with inductive means is carried out the link that elasticity is connected with printed circuit board (PCB); And link is fixed with the form that is clamped in the inductive means, therefore can reduce the detection sensitivity deviation to the staff static capacity.The present invention not only goes in the refrigerator, the temperature that can also be applicable to air conditioner beyond the refrigerator etc. set and the feature operation setup unit in.
