(when the face on the inside of the case in substrate 41 is formed with printing layer 42, more to lean on case compared with it on the inside of the case of substrate 41 Inside) it is laminated with the small metal film of parasitic capacitance.So-called parasitic capacitance is small, and referring to that its parasitic capacitance is less than includes electrostatic capacitance The parasitic capacitance of the substrate of the electrode 52 of sensor, or the parasitic capacitance less than panel 30 in front of the door.In addition, so-called parasitic capacitance Less than the parasitic capacitance of the substrate for the electrode 52 for including static capacity type sensor, refer to such as this implementation form, when including It is small when 1st substrate 54 of the electrode 52 of static capacity type sensor is electrically connected with the 2nd substrate 55 for including microcomputer 57 The parasitic capacitance of the 1st substrate 54 under connected status.Herein, the parasitic capacitance of so-called substrate, base will be configured at by referring to Ground line (ground) of plate etc. generated parasitic capacitance or is equipped on substrate between Wiring patterns and the metal of electrode 52 Parasitic capacitance between the elements such as the microcomputer of static capacity type sensor and electrode 52 etc. affects electrode 52 The total parasitic capacitance of parasitic capacitance, and refer to that substrate in the state that Wiring pattern or element are installed on substrate is whole and post Raw capacitor.Furthermore generated electrostatic capacitance between static capacity type sensor detection electrode and the finger of people, due to substrate The parasitic capacitances such as parasitic capacitance or the parasitic capacitance of metal film can hinder detection of the static capacity type sensor to electrostatic capacitance, therefore Preferably the parasitic capacitance is small.

The metal film small as parasitic capacitance can enumerate various metal films, in this embodiment, using discontinuous vapor deposition An example of the metal film small as parasitic capacitance of film 43.Discontinuous evaporation film 43 refers to be shown because between metallic and due to unbonded Metal film non-conducting and with small parasitic capacitance.Discontinuous evaporation film 43 can be by well known metal evaporation come shape At.Furthermore when being expressed as metal evaporation, wherein needless to say vacuum vapour deposition also includes sputter (sputtering) etc.. The type of metal used in discontinuous evaporation film 43 is not limited.Wherein, tin or alloy, that is, tin alloy comprising tin pass through public affairs The metal evaporation known and oxide layer is formed around metallic, discontinuous evaporation film 43 easy to form.Discontinuous vapor deposition Film 43 has translucency.When face on the inside of the case in substrate 41 is provided with concaveconvex shape, it can also be set in discontinuous evaporation film 43 Set concaveconvex shape.If in the front-back direction by the refrigerating-chamber door 12 between each vertex of recess portion and protrusion in discontinuous evaporation film 43 Length is set as the height of concaveconvex shape, then the height of concaveconvex shape is a few micrometers (μm)~several millimeters (mm) Zuo You.

Face on the inside of the case of discontinuous evaporation film 43 can also be covered by the protective layer 45 of sheet.Protective layer 45 via comprising The adhesive layer 44 of bonding agent and be adhered to discontinuous evaporation film 43.The material of protective layer 45 is not limited.Wherein, when heat-insulated material 32 For comprising foaming carbamate (i.e. comprising foaming carbamate or foaming carbamate in add other materials and At) when, preferably protective layer includes polyvinyl chloride (polyvinyl chloride).

The coloring layer 46 with translucency can also be provided on the outside of the case of substrate 41.The material of coloring layer 46 or formation side Method is not limited, such as can be formed by the face that UV printing etc. is printed on the outside of the case of substrate 41.Outside the case of coloring layer 46 The face of side can also be formed with the adhesive layer 47 for attaching film 40 with panel 30 in front of the door.Adhesive layer 47 has translucency.Adhesive layer Preferably 47 be colorless and transparent in the state of being hardened.Adhesive layer 47 is preferably comprising UV curing agent (when irradiation ultraviolet light Shi Yinqi free radical polymerization or cationic polymerization and the resin hardened).It, can be by by film when adhesive layer 47 includes UV curing agent The face of 40 47 side of adhesive layer is tightly attached to panel 30 in front of the door and from the irradiation of 30 side of panel in front of the door ultraviolet light, and make in front of the door panel 30 with Film 40 is bonded.In addition, can also will indicate that (logo) etc. is printed in panel in front of the door by the methods of silk-screen printing (silkscreen) Face on the inside of 30 case.

Furthermore each layer contiguity in film 40.Such film 40 for example may be disposed at panel 30 in front of the door of refrigerating-chamber door 12 Entire rear side.

An example of the manufacturing method of the refrigerating-chamber door 12 of the above structure is shown.Firstly, will by method illustrated above Respectively it is laminated on substrate 41 layer by layer to manufacture film 40.Secondly, film 40 is adhered to panel 30 in front of the door.Then, by the way that film 40 will be pasted with Panel in front of the door 30 and door inner panel 31 be embedded in door closure and be combined.Then, it is pre-set at the opening portion of door closure etc. certainly, makes Operation portion 50 is slidably inserted into refrigerating-chamber door 12, and operation portion 50 is fixed in refrigerating-chamber door 12, is then shut off the opening portion. Finally, the hole opened up from panel 30 in front of the door or door inner panel 31, by heat-insulated material be injected into panel 30 in front of the door and door inner panel 31 it Between space.In addition, the accommodating container for storing reserve to be fixed on to the face on the inside of the case of inner panel 31.It will be as using hinge etc. Manufactured refrigerating-chamber door 12 as described in upper is installed on the main body of refrigerator 10.

In the refrigerator 10 of this implementation form for having the above structure, in refrigerating-chamber door 12, in the front part of operation portion 50 Point in front of the door between panel 30 and operation portion 50, and the part other than the front of operation portion 50 panel 30 in front of the door with it is heat-insulated Between material 32, it is provided with the discontinuous evaporation film 43 of metal, therefore 12 entirety of refrigerating-chamber door has metallic luster in appearance.Moreover, The parasitic capacitance of the discontinuous evaporation film 43 between panel 30 and the electrode 52 of static capacity type sensor is small in front of the door, therefore when people's When the conductors such as finger come close to or in contact with panel 30 in front of the door, electrostatic capacitance sensor can not be with being hindered by discontinuous evaporation film 43 to institute Situation is stated to be detected.Therefore, good using the operability of static capacity type sensor.

When the parasitic capacitance of the metal films such as discontinuous evaporation film 43 is less than the electrode 52 including static capacity type sensor When the parasitic capacitance of substrate, even if the concaveconvex shape or metal film that change metal film thickness etc. and the case where design for change Under, it is possible to use identical substrate.It is therefore not necessary to change substrate in each design for change, and it can easily increase setting for door Meter variation (design variation).

When the parasitic capacitance of the metal films such as discontinuous evaporation film 43 is less than the parasitic capacitance of panel 30 in front of the door, to electrostatic In the panel in front of the door 30 and metal film that the electrode 52 of capacitance type sensor impacts, the big panel in front of the door 30 of parasitic capacitance is matched The position of the electrode 52 of static capacity type sensor is disposed away to inhibit the influence of parasitic capacitance, thus can precisely into Row utilizes the detection of electrostatic capacitance sensor.

Especially in the case where static capacity type sensor is proximity sensor, it is desirable that the sense of static capacity type sensor Degree is high.In this embodiment, the metal between panel 30 and the electrode 52 of static capacity type sensor is parasitic capacitance in front of the door Small discontinuous evaporation film 43, therefore can keep as sensitivity required by proximity sensor.

Herein, if discontinuous evaporation film 43 includes tin or tin alloy, discontinuous evaporation film 43 is easy to manufacture, and does not connect The parasitic capacitance of continuous evaporation film 43 is small, therefore the operability of static capacity type sensor becomes good.In addition, the one of tin or tin alloy etc. Part metals are difficult to be deposited in panel 30 in front of the door of glass system.But in this implementation form, discontinuous evaporation film 43 is simultaneously indirect Be laminated in the back side of panel 30 in front of the door, but be laminated in be set to panel 30 and static capacity type sensor in front of the door electrode 52 it Between film 40 substrate 41, even if therefore to be difficult to be deposited in the metal of the panel in front of the door 30 of glass system, can also be in panel 30 in front of the door Discontinuous evaporation film 43 is set as between the electrode 52 of static capacity type sensor.

In addition, discontinuous evaporation film 43 and the indirect back side for being laminated in panel 30 in front of the door, but be laminated in and be set to door The substrate 41 of film 40 between front panel 30 and the electrode 52 of static capacity type sensor, therefore the detailed knot to film 40 can be passed through Structure is changed to increase the cosmetic variation for the door observed from the outside of case.

For example, when the discontinuous evaporation film 43 on the inside of the case in substrate 41 is provided with concaveconvex shape, due to substrate 41 and Panel 30 has translucency in front of the door, therefore the concaveconvex shape with metallic luster can be observed from outside case.Also, due to concaveconvex shape Visual effect, can make refrigerator 10 have three-dimensional sense.

In addition, when the surface layer on the inside of the case of substrate 41 is laminated with discontinuous evaporation film 43, the face on the outside of the case of substrate 41 When being laminated with the coloring layer 46 with translucency, back side when observing from outside case through coloring layer 46 can be observed discontinuously to be deposited Film 43, door, which can be observed, has the light for deriving from metallic luster and through colouring.

In addition, when in the manufacturing step in door in front of the door between panel 30 and door inner panel 31 inject fluid heat-insulated material when, Heat-insulated material is contacted with discontinuous evaporation film 43, if heat-insulated material is shunk later, there are discontinuous evaporation films 43 to generate asking for fold Topic.But when matcoveredn 45 is set on the inside of the case in discontinuous evaporation film 43, heat-insulated material and discontinuous evaporation film can be prevented 43 contacts, can prevent discontinuous evaporation film 43 from generating fold.In addition, when heat-insulated material 32 includes foaming carbamate, if protecting Sheath 45 includes polyvinyl chloride, then the adhesion of heat-insulated material 32 and film 40 becomes good.

In addition, if by include discontinuous evaporation film 43 film 40 be set to refrigerating-chamber door 12 panel in front of the door 30 it is entire after Side (case on the inside of), the then whole excellent appearance of refrigerating-chamber door 12.In addition, if the film 40 including discontinuous evaporation film 43 is set to The rear side of the panel in front of the door of the whole door of refrigerator 10, the then whole excellent appearance of refrigerator 10.

For the above implementation form, without departing from the spirit of the invention, can make various changes.It is exemplified below change More example.

(modification 1)

When being provided with film between panel 30 and operation portion 50 in front of the door, if the film include at least sheet substrate with It is laminated in the small metal film of this parasitic capacitance.Therefore, film can be only comprising substrate and the small metal film of parasitic capacitance, can also Including the layer different from the layer recorded in the implementation form.In addition, the small metal film of parasitic capacitance may also set up in substrate On the outside of case.

(modification 2)

As long as the small metal film of parasitic capacitance is at least set to the door including static capacity type sensor.Therefore, example As that the film including the small metal film of parasitic capacitance can also be set to the door including static capacity type sensor, and other than it Door setting includes the film of big metal (such as aluminium or alloy, that is, aluminium alloy comprising the aluminium) film of parasitic capacitance.

(modification 3)

It is set to when by the small metal film of the parasitic capacitance for being provided with concaveconvex shape (this is sentenced for discontinuous evaporation film) When more fan (such as whole) doors, for a part of door in the door, it is set to the height of the concaveconvex shape of discontinuous evaporation film It can also be with other differences.That is, for the height for the concaveconvex shape for being set to discontinuous evaporation film, a part of door and other doors It can also be different.For example, it can be in the altitude range in human eye door, that is, refrigerating-chamber door 11, in refrigerating-chamber door 12, no The height of the concaveconvex shape of continuous steaming plated film is low, and in the door other than it, the height of concaveconvex shape is higher than the height.

Herein, in order to the three-dimensional sense gone out is presented, it is generally desirable to which the height of the concaveconvex shape of discontinuous evaporation film is high.But It is when the height of concaveconvex shape is high, to be easy to produce the interference fringe of light, there are problems that damaging aesthetic feeling.Herein, interference fringe It is easy the generation when the normal direction of Ren Zimen observes door.I.e. interference fringe is easy to generate at the height of human eye.

Therefore, as illustrated in above, if door, that is, refrigerating-chamber door 11, refrigerating-chamber door in the altitude range in human eye A possibility that reducing the height of the concaveconvex shape of discontinuous evaporation film in 12, then can reducing people's visuognosis to interference fringe.And And if improving the height of concaveconvex shape in door other than it, generally speaking three-dimensional sense is presented in refrigerator.

In addition, the multiple regions that door can also have the height for the concaveconvex shape for being set to discontinuous evaporation film different.That is, one The different multiple regions of the height for the concaveconvex shape that may also set up discontinuous evaporation film in fan door.For example, with regard to refrigerating-chamber door 12 For, it is also possible to door central portion and door lower part (such as part of the lower section 2/3 of door) in the altitude range in human eye, The height of the concaveconvex shape of discontinuous evaporation film is low, and on the door top of the position in the height higher than human eye, (such as door is upper The part of side 1/3), the height of the concaveconvex shape of discontinuous evaporation film is higher compared with it.At this time, it may also reduce people's visuognosis is to dry A possibility that relating to striped, and generally speaking three-dimensional sense is presented in refrigerator.
