Description

Freezer

This case is the applying date for September in 2013 4 days, (international application no is PCT/ to Application No. 201380046316.8 JP2013/005220), the divisional application of the patent application of entitled " freezer ".

Technical field

The present invention relates to the door of freezer, more particularly to freezer.

Background technology

In general this freezer sets refrigerating chamber, refrigerating chamber, refrigerating chamber in the freezer main body with thermal insulation Deng these each refrigerating chamber, refrigerating chamber, refrigerating chambers etc. are configured to be opened and closed by door.

The door is configured to, and foreboard on the preceding surface as freezer main body, is used as refrigerating chamber, refrigerating chamber, refrigerating chamber etc. Inner surface inner frame and the framework that integrally links these foreboards and inner frame between filling-foam polyurethane, have The thermal insulation same with freezer main body.

In such freezer, the attractive in appearance i.e. appearance design overall to freezer of its foreboard causes very big shadow Ring, its completeness significantly influences the overall grade of freezer.

Then, in order to improve the appearance design of this, it is known to the freezer (example for being made up of the foreboard of door glass plate Such as, with reference to patent document 1).

Figure 21 represents existing freezer, and its foreboard 101 utilizes the dyed layer 102 that style etc. is formed with by silk-screen printing Pane of tinted glass 103 is constituted, and filling-foam has polyurethane between the pane of tinted glass 103, inner frame 104 and framework 105 106。

According to the structure, the hyaline layer of pane of tinted glass 103 is located at the front side of dyed layer 102, so the color of coloring Depth increase, texture improves, and has the excellent of its appearance design raising compared with the application foreboard that metal is made or resin is made Point.

But, the existing door sets pane of tinted glass insertion section 107 in framework 105, in the pane of tinted glass insertion section The peripheral part of 107 insertion pane of tinted glass 103.Therefore, preceding table of the pane of tinted glass insertion section 107 in pane of tinted glass 103 Expose around face, there is the impaired problem of the appearance design improved using pane of tinted glass 103.In addition, and coloured glass Plate insertion section 107 is same, and a part for the grip frame of the handle (not shown) set in each door is exposed on the preceding surface of glass plate, This also turns into a reason for damaging appearance design.

In the case of particularly having multiple doors, the pane of tinted glass insertion section 107 of the peripheral part of each door, grip frame are (not Diagram) extending part it is many, so door surface it is overall due to pane of tinted glass insertion section 107, protruding for grip frame and cause it Appearance design is greatly damaged.

The present invention is in view of the problem is proposed, its offer can also improve the surface in front of the door in the freezer with multiple Appearance design freezer.

In addition, in general the ratio for the electric power that freezer is used in the family is higher, it is desirable to which suppressing it as much as possible makes Use electric power.Therefore, also motion can be carried out economizing on electricity the structure of operating using optical sensor.Such as light sensors to regulation Illumination more than when carry out common operating.When detecting less than defined illumination, it is believed that customer has gone to bed, and can seldom be opened and closed Food is taken out or be put into the door of freezer, so operated with the economize on electricity of the power operation fewer than common temperature, that is, saves Operating.Now, optical sensor is arranged on illumination in the preceding Surface testing room of door (referring for example to patent document 2, patent document 3).In addition, also having the structure of the indoor illumination of the upper surface detection that optical sensor is arranged on into freezer main body (referring for example to special Sharp document 4).

Figure 22 represents existing freezer, and the freezer sets operating portion 112 in the preceding surface lower portions of door 111, in the behaviour Make the light accepting part 113 that portion 112 sets optical sensor.In addition, Figure 23 represents another existing freezer, in the opposite opened of opposite opened The side end of one door of door 121 is longitudinally disposed operating portion 122, and the light accepting part of optical sensor is set in the operating portion 122 123.And then, Figure 24 represents another existing freezer, and optical sensor 134 is not disposed on door 131, and is provided in freezer The upper surface of main body 135.

In existing freezer shown in such Figure 22 and Figure 23, detect that the light accepting part 113,123 of indoor illumination is set It is placed in operating portion 112,122.Therefore, it is possible to prevent due to user's note used in everyday, paper slip etc. masking light accepting part 113, 123, with can reliably detect indoor illumination intensity carry out economize on electricity operating effect.That is, in order to operate operating portion 112,122, meeting Avoid the operating portion 112,122 sticky, paper slip etc..Therefore, if the operating portion 112,122 set light accepting part 113, 123, then the light accepting part 113,123 will not also be covered by note, paper slip etc., indoor illumination intensity can be reliably detected.

But, when the preceding surface of door is provided with light accepting part 113,123, the light accepting part 113,123 is very obvious, and existing causes The outward appearance of door, the problem that in other words appearance design of freezer declines.

In addition, user operates operating portion 112,122 to set after refrigerated condition when buying freezer, gradually become almost Operating portion 112,122 will not be operated again.Therefore the situation of state sticky, paper slip to cover operating portion 112,122 etc. by Gradual change is more.As a result the effect that light accepting part 113,123 is set in operating portion 112,122 can not be obtained as designed, is deposited Sometimes the problem of indoor illumination intensity can not correctly detected.

Such problem, can be by as the existing freezer shown in Figure 24, in the upper table of freezer main body 135 Face sets optical sensor 134 and is resolved.But user can place article in the upper surface of freezer main body 135, light is passed Sensor 134 is by the shaded by items, and now there is also can not detect the problem of indoor illumination intensity sometimes.

The present invention in view of such problem propose there is provided appearance design can not be made impaired reliably detect indoor photograph The freezer of degree.
