(third embodiment)

Next, being illustrated to third embodiment of the present invention with reference to Fig. 6 and Fig. 7.

Fig. 6 is the figure of the cross-sectional configuration example for the operation portion 20 for indicating third embodiment of the present invention.Fig. 7 is to indicate Fig. 6 Shown in operation portion 20 substrate supporting member 50 structure example stereogram.

Fig. 6 and the operation portion of third embodiment of the present invention shown in Fig. 7 20 (21) and Fig. 2 and shown in Fig. 3 The difference of the operation portion 20 (21) of the first embodiment of the present invention, is the shape of photo-emission part 80,81.In addition to light reflection It is practically identical other than the shape in portion 80,81, therefore assign identical symbol and omit the description.

Such as Fig. 6 and as shown in Figure 7, photo-emission part 80,81 is continuously formed along the Z direction.Photo-emission part 80 with it is more The arrangement of a LED44 is accordingly formed along the Z direction, the arrangement of photo-emission part 81 and multiple LED45 accordingly shape along the Z direction At.

As shown in Figure 6, photo-emission part 80 has the first light reflection surface 80A and the second light reflection surface 80B.Light reflection Portion 81 has the first light reflection surface 81A and the second light reflection surface 81B.

First light reflection surface 80A and the second light reflection surface 80B is preferably connected with 90 degree, the first light reflection surface 81A and second Light reflection surface 81B with 90 degree it is also preferred that connected.

The first light reflection surface 80A can draw after the light L reflections 1 for making LED44 are taken second place to the second light reflection surface 80B as a result, It leads, the second light reflection surface 80B can make the light L of LED44 carry out the second secondary reflection, and by the through hole of substrate 40 48 to door 3 (4) front (directions Y1) guiding.Equally, the first light reflection surface 81A can be after the light L reflections 1 for making LED45 be taken second place to second Light reflection surface 81B guiding, the second light reflection surface 81B can make the light L of LED45 carry out the second secondary reflection, and pass through substrate 40 Through hole 49 is guided to the front (directions Y1) of door 3 (4).

In this way, LED44,45 light L can respectively reflection 2 times after, by the through hole 48,49 of substrate 40, to door 3 (4) front (directions Y1) irradiation.Therefore, with by the light of LED directly forwards irradiate the case where compared with, can increase from LED44,45 to substrate 40 through hole 48,49 until distance.Therefore, it is possible to increase the diffusion of light L, in door 3 (4), behaviour The deep or light of light L can be mitigated and irradiate milder light L by making portion 20 (21).

As shown in Figure 6, LED44,45 are surrounded by substrate 40 and photo-emission part 80,81.LED44 is generated as a result, The light L that light L and LED45 are generated will not be leaked to the outside, and light L can not be such that light quantity reduces, and pass through through hole 48,49 respectively It is irradiated to the directions Y1.Light quantity therefore, it is possible to prevent user from visually observing is reduced, therefore can improve operation portion 20,21 It is visual.

In the refrigerator 1 of the embodiments of the present invention, there is effect as following.

In the refrigerator 1 of each embodiment, LED44, the 45 light L generated are anti-using light in the region of 40 inside of substrate Portion 60,61,80,81 is penetrated to reflect, thus, it is possible to longer ensures distance (optical path length).In this way, light L can be by using light Reflecting part 60,61,80,81 increases distance, therefore can reduce the brightness, bright with the peripheral portion of light L of the central part of light L It is deep or light between brightness, and mitigate the deep or light of light L.

That is, when light L is irradiated by the through hole 48,49 of substrate 40 to the front of door 3 (4), light L is by using light reflection Portion 60,61,80,81 increases distance, therefore can increase the diffusion of light L.Therefore, in door 3 (4), operation portion 20 (21) energy The deep or light of light L is enough mitigated, and irradiates milder light L towards the front of door 3 (4).In contrast, lead to when without using reflecting part Cross through hole directly to the front irradiation light of door when, the diffusion of light becomes smaller, therefore can not mitigate the deep or light of light L.

In particular, in third embodiment shown in Fig. 6, LED44,45 light L it is multiple by reflection, therefore can be substantially Degree increase from LED44,45 to substrate 40 through hole 48,49 until distance.Therefore, it is possible to increase the diffusion of light L, in door 3 (4) in, operation portion 20 (21) can mitigate the deep or light of light L and irradiate milder light L.

LED44,45 also can obliquely be configured relative to substrate 40.By relative to substrate 40 with angled LED44, 45 and photo-emission part, light L advance as the crow flies.

LED44 shown in Fig. 2,45 and LED44 shown in Fig. 4,45 are configured relative to substrate 40 with an angle of 90 degrees degree, light L To the direction of positive side project, i.e. light L after parallelly being projected relative to the back side 42 of substrate 40, by photo-emission part 60, 61 reflections.As a result, light L by 1 secondary reflection by from the through hole 48,49 of substrate 40 project.

Light L to the angle of photo-emission part incidence be preferably 45 degree or less.If the angle of the incidence is smaller, even if passing through 1 secondary reflection can also project almost straight light L.

From distance of the substrate 40 until photo-emission part be preferably 8mm or less.In addition, 40 being passed through from photo-emission part to substrate Distance until through-hole 48,49 is preferably 8mm or less.

The light L of LED somewhat upwardly has and angularly passes through base relative to can not be straight before refrigerator 1 The through hole 48,49 of plate 40 simultaneously exports.Although operation portion 20,21 is in the position of the comparison of door 3 (4) on the lower as a result, when from When operation portion 20,21 projects downward light, user is possible to be difficult to confirm the luminance of light.Therefore, light L preferably with level Direction is compared to be projected slightly offset towards Shangdi.

LED is in the position relationship being staggered in the up-down direction with photo-emission part, is located at photo-emission part compared with LED upper Side.Light L advances upward.

Preferably, other than the reflecting surface of photo-emission part 60,61,80,81 becomes upward relative to gravity direction, that is, Z-direction Direction.This reason it is assumed that even if entering dust, dust will not be stacked into the reflecting surface of photo-emission part 60,61,80,81.

Preferably, the reflecting surface of photo-emission part 60,61,80,81 is set to 42 side of the back side towards substrate 40.As a result, When operator is relative to 50 assembling substrates 40 of substrate supporting member, without worrying that operator mistakenly touches photo-emission part 60,61,80,81 reflecting surface.

Preferably, integrally formed, process photo-emission part 60,61,80,81 in the molding of substrate supporting member 50. As a result, with later in substrate supporting member install photo-emission part the case where compared with, the photo-emission part 60 of substrate supporting member 50, 61,80,81 profile angle is difficult to generate normal scatter.

Preferably, in the recessed of the substrate supporting member 50 opposed with the side the back side 42 of substrate 40 (LED44,45 mounting surface) The inside in portion carries out the mirror finish of photo-emission part 60,61,80,81.That is, the assembling substrates 40 in substrate supporting member 50 The inside of recessed portion locally carries out mirror finish.

Light L from each LED44,45 can also for example be divided into 2 parts by photo-emission part to show.In this case, For example, the deflection mirror surface by making photo-emission part 60,61,80,81, thus makes light L-shaped longer at obtaining.

As described above, the refrigerator 1 of embodiments of the present invention has refrigerator main body 2, the front openings portion to refrigerator main body 2 The door 3 (4) being opened and closed and the operation portion 20 (21) being arranged before door 3 (4).Operation portion 20 (21) has：One base Plate 40, the electrostatic that on the surface 41 as one side there is the variation of the electrostatic capacitance to being generated due to contact to be detected connect Touch circuit portion 43, on the back side 42 as another side equipped with as light-emitting component LED44,45；And substrate support Part 50,42 side of another side, that is, back side of supporting substrate 40, and with to from as light-emitting component LED44,45 light L carry out The photo-emission part 60,61 of reflection.Be provided with through hole 48,49 on the substrate 40, the through hole 48,49 for by photo-emission part 60, 61 reflections pass through as the LED44 of light-emitting component, 45 light L, and are guided to the front of door 3 (4).

It is used as substrate as a result, without using multiple, and a substrate 40 is used only, reduces operation of the configuration on door 3 (4) The number of components in portion 20 (21), thus, it is possible to cost of implementation reductions.Further, since a substrate 40 is used only, therefore can obtain To the effect for ensuring adiabatic thickness brought by the reduction of thickness direction.

As illustrated in fig. 2, photo-emission part 60,61 takes second place in the light L reflection 1 for making light-emitting component i.e. LED44,45 Afterwards, light L is made to be guided to the front of door 3 (4) by through hole 48,49 of substrate 40.

As a result, LED44,45 light L carry out 1 secondary reflection, thus light L by through hole 48,49 of substrate 40 to door 3 (4) front guiding.Therefore, the light path of light L can increase distance, therefore energy before the through hole 48,49 by substrate 40 Enough increase the diffusion of light L.Therefore, in door 3 (4), operation portion 20 (21) can mitigate the deep or light of light L, and towards door 3 (4) Milder light L is irradiated in front.

As illustrated in Figure 4, photo-emission part 60,61 has light occlusion part 60H, 61H, as light-emitting component LED44,45 are surrounded by light occlusion part 60H, 61H and photo-emission part 60,61.

Thereby, it is possible to make LED44, the 45 light L generated not to leak to the outside, and LED44, the 45 light L generated will not It interferes.Light L can not reduce light quantity as a result, and be irradiated respectively to the directions Y1 by through hole 48,49 ground.Therefore, it is possible to It prevents the light quantity that user visually observes from reducing, therefore the visuality of operation portion 20,21 can be improved.

As the example shown in figure 6, photo-emission part 80,81 has first light reflection surface 80A, 81A and the second light reflection surface 80B, 81B, first light reflection surface 80A, 81A after the light L for making LED44,45 reflects 1 time respectively to the second light reflection surface 80B, 81B is guided, and second light reflection surface 80B, 81B reflects light L and make it through the through hole 48,49 of substrate 40 and to door 3 (4) front guiding.

As a result, LED44,45 light L after reflecting 1 time by first light reflection surface 80A, 81A, by the second light reflection surface 80B, 81B carry out the second secondary reflection, and thus light L is guided by the through hole 48,49 of substrate 40 to the front of door 3 (4).Therefore, The light path of light L increases distance before the through hole 48,49 by substrate 40, therefore can increase the diffusion of light L.Therefore, exist In 3 (4) of door, operation portion 20 (21) can mitigate the deep or light of light L, and milder light L is irradiated towards the front of door 3 (4).

As illustrated by Fig. 2, Fig. 4 and Fig. 6, on the surface 41 as one side of substrate 40, configured with making LED44,45 the component 70 of covering that penetrates of light L.

The component 70 of covering covers the electrostatic contact circuit portion 43 on the surface 41 of substrate 40 as a result, further, it is possible to make door Aesthetics in the appearance design of 3 (4) is good.

LED44 shown in Fig. 9,45 are configured relative to the back side 42 of substrate 40, thus LED44,45 light L in substrate 40 The back side 42 towards photo-emission part 160 project after, by 160 diffusing reflection of photo-emission part.

Electrostatic contact circuit portion 43 shown in Fig. 9 and each LED44,45 are electrically connected with control unit 100.Control unit 100 is matched It is placed in refrigerator main body 2 shown in Fig. 8.Electrostatic contact circuit portion 43 is, when detecting that the electrostatic contact by the finger of user draws When the electrostatic contact input risen, receive contact input signal.In addition, control unit 100 is, such as when detecting that electrostatic contact inputs When, it carries out LED44,45 light action.

Fig. 9 and substrate supporting member shown in Fig. 10 50, by material, such as plastic production with electrical insulating property.Base Plate support member 50 is substantially planar, but has substrate embedded division 51A, 51B and mounting protrusion portion 52,53,55,56.

Photo-emission part 160 shown in Fig. 9 is for example preferably made by the resin of white color system.Photo-emission part 160 has main part Divide 161 and marginal portion 162,163.Marginal portion 162,163 is formed from main part 161 along X-Z plane.Edge Part 162,163 is respectively embedded in substrate embedded division 51A, 51B of substrate supporting member 50, and thus photo-emission part 160 is fixed on Substrate supporting member 50.

As illustrated in Figure 9 like that, substrate supporting member 50 configures in the opening portion 3R of the front panel 3F of door 3.Substrate Substrate embedded division 51A, 51B of support member 50 has in 57 side of the surface of substrate supporting member 50 for for aforesaid substrate 40 Embedded and fixed sunk part.The depth K of the sunk part of substrate embedded division 51A is suitable with the thickness of substrate 40.

Substrate 40 is installed by the substrate embedded division 51A of embedded substrate supporting member 50 as a result, the surface 41 of substrate 40 Become flush with substrate supporting member 50.42 side of the back side of substrate 40 such as by stickup adhesive be fixed on substrate insertion Portion 51A.

As shown in Figure 9, mounting protrusion portion 52,53,55,56 is put down in the back side of substrate supporting member 50 towards Y-direction It is provided projectingly capablely.These mounting protrusion portions 52,53,55,56 have substantially L fonts, are arranged for passing through operation portion 20 Construction side that is embedded and being fixed on door 3.Operation portion 20 can be securely fixed relative to door 3 as a result,.

As shown in Figure 9, substrate 40 has multiple through holes 48,49 on the position faced with photo-emission part 160.Light The main part 161 of reflecting part 160 is arranged to, by the lateral Y-direction in the back side of substrate supporting member 50 it is outstanding in a manner of it is swollen Swollen, main part 161 is flat surface parallel with substrate 40 and along X-Z plane.Main part 161 covers the more of substrate 40 A through hole 48,49 and configuration 42 side of the back side of substrate 40 multiple LED44,45.

As shown in Figure 9, multiple through holes 48 of substrate 40 are separately formed at the multiple of the back side 42 of substrate 40 On the position of the sides LED44.Equally, multiple through holes 49 of substrate 40 are separately formed at the multiple of the back side 42 of substrate 40 On the position of the sides LED45.

Figure 11 be indicate to be configured on the substrate 40 multiple through holes 48,49 and multiple LED44,45 example main view Figure.

As shown in Figure 11, multiple through holes 48,49 separate same intervals along the Z direction and arrange respectively in-linely. Equally, multiple LED44,45 corresponding respectively with the position of multiple through holes 48,49, separate same intervals and arrange in-linely.It passes through Through-hole 48 is formed separately outward in the Y direction from the position of corresponding adjacent LED44.Equally, through hole 49 is from correspondence Adjacent LED45 position, be formed separately outward in the Y direction.

Fig. 9 is returned to, the inner face of photo-emission part 160 is for making the light L of LED44,45 for example towards diffusing reflection from all directions Diffusing reflection face 90.Photo-emission part 160 preferably has the cross sectional shape of substantially hull bottom type.The main part 161 of photo-emission part 160 Inner face have flat surface 91 and curved face part 92,93.

Flat surface 91 is the part facing with the position of LED44,45 and through hole 48,49, parallel with X-Z plane. Curved face part 92,93 is the both ends part of flat part 91, such as with 1/4 circular section shape.Flat surface 91 and curved face part 92, 93 inner face becomes for making the irreflexive diffusing reflection faces the light L of LED44,45 90.Curved face part 92,93 may be, such as lead to It is parabolic shape to cross cross-section.

In this way, the diffusing reflection face 90 of photo-emission part 160 is not convex form by cross-section, and using has flat surface 91 Shape the reason of be, minimize the thickness of the operation portion 20 (21) in Y-direction.

Thickness in Y-direction due to minimizing operation portion 20 (21) as a result, passes through the thickness of operation portion 20 (21) The heat insulating material doses of corresponding amount can be increased in door 3 (4) by spending the reduction in direction, therefore can obtain ensuring the effect of adiabatic thickness Fruit.

As described above, photo-emission part 160 shown in Fig. 9 is made by white color system resin.The diffusing reflection face 90 of photo-emission part 160 Flat surface 91 and curved face part 92,93 inner face, preferably by carry out lucigenin working process.For example, photo-emission part 160 is unrestrained The flat surface 91 and curved face part 92,93 of reflecting surface 90, do not implement the gloss finish such as electroplating processes, and in a manner of becoming smooth Implement the lucigenin working process of mirror-like.Thereby, it is possible to make the light L diffusing reflections of LED44,45.

But, it is not limited to this, the flat surface 91 and curved face part 92,93 in the diffusing reflection face 90 of photo-emission part 160, The concave-convex rough surface brought can be formed.Thereby, it is possible to make the light L diffusing reflections of LED44,45.

As shown in Figure 9, LED44 generate light L by photo-emission part 160 diffusing reflection face 90 flat surface 91 and song Facial 92,93 diffusing reflections, through the component 70 of covering by through hole 48 of substrate 40.Equally, the light L that LED45 is generated By the flat surface 91 in the diffusing reflection face 90 of photo-emission part 160 and the inner face diffusing reflection of curved face part 92,93, pass through passing through for substrate 40 Through-hole 49 and penetrate covering component 70.

Therefore, LED44,45 generate light L, towards the front of door 3, that is, directions Y1 with spread or dispersed state shine It penetrates.

Thus it is preferred to be, even if can reduce or eliminate so-called note if the LED44 that optical element, which is light, to be concentrated, 45 Mesh sense, this gaze at sense be due to light L is concentrated and the light and shade of light distinguishes apparent phenomenon in operation portion 20 (21) shown in Fig. 8.

Due to that can increase the diffusion towards the light L in the directions Y1, the operation portion 20 (21) of door 3 (4) can mitigate light L It is deep or light and irradiate milder light L, therefore can prevent from so-called gazing at sense and producing the feeling of high class of operation portion 20 (21).

In addition, LED44,45 light L respectively in photo-emission part 160 after diffusing reflection, pass through the through hole 48 of substrate 40 And it is irradiated towards the front of door 3 (4), that is, directions Y1.It therefore, can compared with the case where making the light of LED directly irradiate forwards Increase from LED44,45 to substrate 40 through hole 48,49 until distance.

Therefore, it is possible to increase the diffusion of light L, the operation portion 20 (21) of door 3 (4) can mitigate the deep or light of light L, and irradiate more Soft light L.In operation portion 20 (21), LED44,45 can irradiate milder light L, thus operation portion 20 (21) can It shows feeling of high class when being illuminated, and improves refrigerator 1 feeling of high class of itself.

As shown in Figure 9, the component 70 of covering is, for example, the plastic sheet component with translucency.Covering is used Component 70 can make the above-mentioned light L for having passed through through hole 48,49 towards door 3 front side penetrate.The component 70 of covering Can be transparent material, or in order to improve the value in appearance design and with the outside plate color of refrigerator main body 2 matchingly into Row coloring.As shown in Figure 9, the X-direction and Z of the size and substrate 40 of the X-direction and Z-direction of the component 70 of covering The size in direction is roughly the same or slightly larger.

As shown in Figure 9, the component 70 of covering is pasted onto surface 41 and the substrate supporting member 50 of substrate 40 Surface 57.Preferably, the surface of the component 70 of covering and the surface of the front panel 3F (4F) of door 3 are set to flush.By This, even if operation portion 20 (21) can eliminate the step difference on door 3 (4) if being configured at door 3 (4), and improves the outer of door 3 (4) See the value in design.

In the refrigerator 1 of the 4th embodiment of the present invention, the structure example and configuration example and door of the operation portion 20 on door 3 The structure example and configuration example of operation portion 21 on 4 are practically identical.Operation portion 20 (21) using one piece of circuit substrate 40, Without as in the past using the substrate of multiple circuits.Therefore, it is possible to reduce the thickness in operation portion 20 (21) Y-direction of itself Degree.Furthermore it is possible to reduce the number of components of operation portion 20 (21), cost of implementation reduces.By the reduction of thickness direction, in door 3 (4) it can increase the heat insulating material doses of corresponding amount in, therefore can obtain ensuring the effect of adiabatic thickness.

(the 5th embodiment)

Next, 2 and Figure 13 illustrates the 5th embodiment of the present invention referring to Fig.1.

Figure 12 is the figure of the cross-sectional configuration example for the operation portion 20 for indicating the 5th embodiment of the present invention.Figure 13 is to indicate The front view of example configured with multiple through holes 48,49 and multiple LED94 in substrate 40 shown in Figure 12.

Shown in the operation portion 20 (21) Yu Fig. 9 and Figure 10 of 5th embodiment of the invention shown in Figure 12 and Figure 13 The present invention the 4th embodiment operation portion 20 (21) difference, be the configuration quantity of the i.e. LED94 of light-emitting component with And allocation position.Part other than LED94 is practically identical, therefore assigns identical symbol and omit the description.

Multiple LED94 shown in Figure 12 are that as illustrated in Figure 13 like that, multiple through holes 48,49 separate along the Z direction Same intervals arrange respectively in-linely.Equally, on positions of the multiple LED94 of 1 row between multiple through holes 48,49, in the side Z On the position being slightly staggered upwards, separates same intervals and arrange in-linely.

In the arrangement example, multiple LED94 of 1 row discretely configure multiple through holes 48 in 1 row and are passed through with the multiple of 1 row The middle position of through-hole 49.The quantity of LED94 is fewer than the quantity of through hole 48,49.

In this way, the configuration quantity of the LED94 in the 5th embodiment than in the 4th embodiment LED44,45 configuration Quantity is few.But by the way that the luminous quantity of each LED94 is for example increased to 100% from 50%, even if the thus configuration number of LED94 It measures less, the light quantity of the light L derived from the through hole 48,49 can be also substantially ensured in operation portion 20 (21).

The light L of one LED94 is passed through after diffusing reflection by being on the substrate 40 from 2 of the position that LED94 is detached Through-hole 48,49 can fully carry out the illumination of operation portion 20 (21) if even if thus reducing the quantity of LED.Pass through reduction The configuration quantity of LED94, thus, it is possible to realize the reduction of the number of components of operation portion 20 (21) and cost reduction.

As shown in Figure 12, the light L that multiple LED94 of 1 row are generated, by photo-emission part 160 diffusing reflection face 90 it is flat Smooth face 91 and curved face part 92,93 diffusing reflections, through the component 70 of covering by through hole 48 of substrate 40.

The light L that LED94 is generated as a result, is in the state of diffusing reflection, from through hole 48 towards front, that is, Y1 of door 3 (4) Direction is irradiated.Therefore, even the LED94 that light is concentrated, also it can reduce or eliminate due to light L concentrations and in operation portion 20 (21) light and shade of light distinguishes apparent phenomenon, i.e. so-called gazes at sense in.Since the expansion towards the light L in the directions Y1 can be increased It dissipates, therefore the operation portion 20 (21) of door 3 (4) can make the deep or light mitigation of light L and irradiate milder light L, thus, it is possible to prevent It is so-called to gaze at sense, and produce feeling of high class.

In addition, the light L of LED94 respectively after photo-emission part 160 is diffusely reflected by through hole 48 of substrate 40 court It is irradiated to the front of door 3 (4), that is, directions Y1.Therefore, compared with the case where directly irradiating the light of LED forwards, can increase Distance from LED94 to substrate until 40 through hole 48,49.The diffusion of light L, the operation portion 20 (21) of door 3 (4) can be increased It can make the deep or light mitigation of light L and irradiate softer light L.

In this way, in operation portion 20 (21), milder light L can be irradiated, therefore can be shown in operation portion 20 (21) Feeling of high class when showing to be illuminated can improve refrigerator 1 feeling of high class of itself.

In the refrigerator 1 of the 5th embodiment of the present invention, the structure example and configuration example and door of the operation portion 20 in door 3 The structure example and configuration example of operation portion 21 in 4 are practically identical.Operation portion 20 (21) using one piece of circuit substrate 40, Rather than as in the past using the substrate of multiple circuits.Therefore, it is possible to reduce in operation portion 20 (21) Y-direction of itself Thickness.Furthermore it is possible to the number of components of operation portion 20 (21) is reduced, and being capable of cost of implementation reduction.Pass through subtracting for thickness direction It is few, the heat insulating material doses of corresponding amount can be increased in door 3 (4), therefore can obtain ensuring the effect of adiabatic thickness.

(sixth embodiment)

Next, 4 the sixth embodiment of the present invention is illustrated referring to Fig.1.

Figure 14 is the figure of the cross-sectional configuration example for the operation portion 20 for indicating the sixth embodiment of the present invention.Shown in Figure 14 originally The operation of the operation portion 20 (21) of the sixth embodiment of invention and Fig. 9 and the 4th embodiment of the present invention shown in Fig. 10 The difference in portion 20 (21) is the shape of photo-emission part 180.It is practically identical other than the shape of photo-emission part 180, because This assigns identical symbol and omits the description.

Photo-emission part 180 is for example preferably made by the resin of white color system.Photo-emission part 180, which has, to be faced with LED44,45 Part becomes the cross sectional shape of the dome-type of spherical surface.When the thickness of the Y-direction to operation portion 20 (21) is not particularly limited, such as Illustrated by Figure 14 like that, photo-emission part 180 can use section semi-circular shape.The inner face of the spherical surface of photo-emission part 180 is to use In making the irreflexive diffusing reflection faces the light L of LED44,45 183.

In this way, the photo-emission part 180 of dome-type has main part 185 and marginal portion 181,182.Marginal portion 181,182 extend from main part 185 and are formed in X direction.Marginal portion 181,182 passes through embedded substrate supporting member 50 substrate embedded division 51A, 51B to fix relative to substrate supporting member 50.

The diffusing reflection face 183 of photo-emission part 180 is preferably by carry out lucigenin working process.For example, diffusing reflection face 183 is unreal The gloss finish such as electroplating processes are applied, and implement the lucigenin working process of mirror-like in a manner of becoming smooth.Alternatively, diffusing reflection Face 183 can also be formed as the concave-convex rough surface brought.

As shown in Figure 14, the light L that LED44 is generated passes through the through hole 48 of substrate 40 by 183 diffusing reflection of diffusing reflection face And through the component 70 of covering.Equally, the light L that LED45 is generated passes through the perforation of substrate 40 by 183 diffusing reflection of diffusing reflection face Hole 49 and the component 70 for penetrating covering.As a result, LED44,45 generate light L towards the front of door 3, that is, directions Y1 diffusely according to It penetrates.

As described above, having refrigerator main body 2, right from the refrigerator 1 of the 4th embodiment to the sixth embodiment of the present invention The door 3 (4) that the front openings portion of refrigerator main body 2 is opened and closed and the operation portion 20 (21) being set to before door 3 (4).Behaviour Making portion 20 (21) has：One substrate 40 has the electrostatic capacitance to being generated due to contact on the surface 41 as one side The electrostatic contact circuit portion 43 that is detected of variation, equipped with as light-emitting component on the back side 42 as another side LED44、45、94；And substrate supporting member 50, supporting substrate 40, and it is anti-with being carried out to the light L from LED44,45,94 The photo-emission part 160,180 penetrated.

Photo-emission part 160,180 is with the irreflexive diffusing reflection faces 90,183 the light L of LED44,45,94 are made, in substrate 40 On be provided with will be from the light L of LED44,45,94 in the diffusing reflection face 90 of photo-emission part 160,180,183 diffusing reflections to door 3 (4) Front guiding through hole 48,49.

A substrate 40 is used as a result, therefore compared with the case where using 2 or more substrates, can be reduced and be matched It is placed in the number of components of the operation portion 3 (4) of door, thus, it is possible to cost of implementation reduction, the reduction band by thickness direction can be obtained The effect for ensuring adiabatic thickness come.Also, the light L of light-emitting component as LED44,45,94, can be by photo-emission part 160, it is guided to the front of door 3 (4) by the through hole 48,49 of substrate 40 after 180 diffusing reflections, therefore LED44,45,94 Light L will not be guided directly from through hole.

That is, the light of light-emitting component will not be directly entered eyes, therefore it can reduce or eliminate and be produced in operation portion 20 (21) What the raw so-called light by LED generated gazes at sense.Therefore, when being illuminated in operation portion 20 (21), it can show that height Grade sense.

Photo-emission part 160 becomes the cross sectional shape of the hull bottom type of flat surface 91 with the part faced with light-emitting component, puts down Smooth face 91 is diffusing reflection face 90.As a result, since diffusing reflection face 90 is flat surface 91, the feelings with the diffusing reflection face for using convex Condition is compared, and the size of the thickness direction (Y-direction) of operation portion 3 (4) can be minimized.Since operation portion 20 can be reduced to the greatest extent (21) the thickness in Y-direction, therefore by the reduction of thickness direction, the exhausted of corresponding amount can be further increased in door 3 (4) Hot material amount can obtain the effect for ensuring adiabatic thickness.

As illustrated in Figure 14 like that, photo-emission part 180 has the hemisphere that the part faced with LED44,45 becomes spherical surface The inner face of the cross sectional shape of type, spherical surface is diffusing reflection face 83.As a result, in the ruler of the thickness direction (Y-direction) to operation portion 3 (4) It is very little be not particularly limited in the case of, can apply the photo-emission part 180 shape.

Photo-emission part 160,180 is made by white color system resin, and the diffusing reflection face of photo-emission part is by carry out gloss finishing Reason.Photo-emission part 160,180 is after making the light L diffusing reflections of the i.e. LED of light-emitting component as a result, by the through hole 48 of substrate 40, 49, even LED44,45,94 that thus light is concentrated, it can also eliminate the institute in the phenomenon that light is concentrated, i.e. operation portion 20 (21) Meaning gazes at sense.

Due to that can increase the diffusion towards the light L in the directions Y1, the operation portion 20 (21) of door 3 (4) can mitigate light L It is deep or light and irradiate milder light L, thus, it is possible to prevent it is so-called gaze at sense, and produce feeling of high class.

Photo-emission part 160,180 is made by white color system resin, and the diffusing reflection face of photo-emission part 160,180 is concave-convex to bring Rough surface.Photo-emission part is after making the light L diffusing reflections of the i.e. LED of light-emitting component as a result, by the through hole 48,49 of substrate 40, Even the LED44 that thus light is concentrated, 45 can also eliminate the so-called note in the phenomenon that light L is concentrated, i.e. operation portion 20 (21) Mesh sense.
