The present invention relates to be used for the lighting apparatus for refrigerator of refrigerator intraoral illumination.
The scheme of a large amount of lighting apparatus for refrigerator has been proposed up to now.Its representational example as shown in figure 13, with incandescent lamp be used as lamp inside the box 1 be contained in in the recess 2a of case 2, cover with the uniform lamp inside the box cover 3 of wall thickness and to form.Adopt this structure, along with the switch of door of refrigerator, the lamp 1 in the refrigerator is lighted, and extinguishes.And the reflecting plate of the light of symbol 4 expression reflection lamp inside the box 1.
But in recent years, it is big that refrigerator obviously becomes, and can not evenly throw light in the refrigerator when device shown in Figure 13 is used in this large-scale refrigerator, has only the illumination of locality.And in recent years, along with popularizing of middle part cooling type refrigerator (refrigerating chamber is in the superiors of refrigerator, and refrigerating chamber is in the refrigerator in middle level), the allocation position of lighting device has raise.Therefore, in the device of Figure 13, the light that lamp inside the box 1 penetrates directly enters in user's the eyes, stimulates eyes.So, proposed a plurality of electric lights to be set in refrigerator as real the opening as described in clear 55-2393 number of Japan's special permission communique, it is even to seek the refrigerator intraoral illumination, or opens as described in flat 2-103691 number as this special permission communique is real, uses the fluorescent lamp of the big excellent performance of illumination zone.
But, the structure of a plurality of electric lights is set in refrigerator, with the electric light number that increases in the refrigerator, electric light wiring number of parts and wiring operation number.Therefore, will cause cost to rise.And, the structure of use fluorescent lamp, the starting circuit that needs fluorescent lamp starter and choke coil etc. to form.Therefore, number of parts increases, and causing cost increases.
And under such low temperature, the luminous power of fluorescent lamp is poor in refrigerator, must use heating element to wait to improve the temperature around the fluorescent lamp.As a result, cause temperature rising in the refrigerator, cooling capacity descends.And along with the switch of door of refrigerator, fluorescent lamp switch continually closes, and the life-span of fluorescent lamp might shorten.The present invention be directed to described situation and make, its purpose is to provide the stimulation to eyes little, does not reduce the cooling capacity of refrigerator, can make the refrigerator intraoral illumination even, and cheap lighting apparatus for refrigerator.
Lighting apparatus for refrigerator of the present invention has, being connected and installed in the cold air that freezing cycle device is produced introduces on the pipeline of refrigerating chamber, simultaneously along the sidewall of described refrigerating chamber and the matrix part of ceiling wall configuration, with the light source portion of forming by the incandescent lamp that is installed on this matrix part, and combine with described matrix part, cover the Transparent lamp shade of described light source portion.This lampshade have with desired refrigerator in the corresponding Thickness Distribution of Illumination Distribution, can regulate its light transmittance.
But reflection is from the reflecting part integrated setting of the light of light source portion or be provided with separately, and this reflecting part is material with the metal, also can take the additional structure that does not reflect from the function of the heat ray of light source portion.
And, also can use resin that pipeline and matrix part are formed one, can also when making this pipeline, also be made of one reflecting part with resin.
In the lighting device of refrigerator of the present invention, pipeline the cold air introducing refrigerating chamber of freezing cycle device generation is connected with the matrix part that light source portion is installed, and disposes along the sidewall and the ceiling wall of refrigerating chamber, therefore, can be effectively to throwing light in the refrigerating chamber.By means of the Transparent lamp shade that covers light source portion, can adjust light transmittance suitably, make refrigerator have desired Illumination Distribution.
Integrated setting or the light reflecting part of reflection from light source portion is set separately is to seek to improve the illumination in the refrigerator.And, make not reverberation ray of reflecting part, prevent that the cooling effectiveness of refrigerating chamber from descending.
Pipe section and matrix part also can be used the resin integral forming.Moreover reflecting part is also used the resin integral forming when this pipeline is made, and then the making of lighting device is just easy.

According to Fig. 1 to Fig. 8 the 1st embodiment is described below.At first, at Fig. 4, refrigerator main body 11 is the case shape of front openings, makes the outside that outer container 11b is assembled in interior case 11a, puts into heat-barrier material 11c (see figure 1)s such as foaming urethane fat between interior case 11a and outer container 11b.The main body 11 inner central refrigerating chambers 12 that form at this refrigerator form refrigerating chamber 13 at these refrigerating chamber 12 upsides.Refrigerating chamber 12 and refrigerating chamber 13 usefulness dividing plate 14a are separated interior case 11a, and the peristome of refrigerating chamber 12 and refrigerating chamber 13 fronts all is to prop up the door of refrigerator (not shown) that is held in refrigerator main body 11 in order to the frame axle to cover.14b represents refrigerating chamber is divided into the shelf of multilayer.
In refrigerator main body 11, the back side of refrigerating chamber 12 forms the cooler reception room (not shown) that holds freezing cycle device (not shown) usefulness.The cold air that this freezing cycle device generates directly enters in the refrigerating chamber 12, makes the temperature that remains in regulation in the refrigerating chamber 12.Cold air device reception room is used by the synthetic resin injection molded of the white refrigerator internal pipeline 15 that forms that is shaped and is connected with refrigerating chamber 13.This refrigerator internal pipeline 15 is installed along the back side of interior case 11a, and the part of the cold air that freezing cycle device generates rises from be located at a plurality of gas outlet 15a on refrigerator internal pipeline gas that spues respectively in refrigerating chamber 13 through this refrigerator internal pipeline 15.
As shown in Figure 2, outstanding protuberance 16 is integrally formed at the top of refrigerator internal pipeline 15 towards the place ahead, and the ceiling in interior case 11a disposes.These protuberance 16 left and right sides have big peristome 16a, 16a, and its central portion has little peristome 16b.Be formed with refrigerator lamp inside the box installation portion 17 in the place ahead of peristome.This installation portion 17 is made of outstanding forward two base portion 17a, 17a and the lamp socket portion that is located at the L font of a base portion 17a.Be screwed in as the incandescent lamp of lamp inside the box 18 on the electrode (not shown) of socket 17b, this lamp inside the box 18 is lighted along with the switch of door of refrigerator or is extinguished.
At protuberance 16 transversely long heat shield panel 19 is installed, to block its peristome 16a, 16b and 16c.The reflection of the heat that these heat shield panel 19 restriction lamp inside the box 18 produce when lighting, thermal deformation takes place in case 11a in preventing.As shown in Figure 1, this heat shield panel is the inclination pars convoluta 19b of the facial 19a of level, L font and vertical surface part 19c to be linked together form.This heat shield panel plays a part the light of reflection lamp inside the box 18.
As shown in Figure 2, vertical surface part 19c is disposed at the back side of lamp inside the box 18, and the facial 19b that tilts is disposed at the both sides of vertical surface part 19c, covers each peristome 16a.Fig. 7 is the drawing in side sectional elevation of the configuration relation of indication lamp 18 and heat shield panel 19, and each facial 19b that tilts forwards tilts gradually, thereby lamp 18 is surrounded along with departing from vertical surface part 19c.Two point locking wire on the heat shield panel 19 of Fig. 2 is used for representing the shape of heat shield panel 19.
Heat shield panel 19 usefulness reflecting metal material are made, and reflection is from the light irradiation refrigerating chamber 13 and the refrigerating chamber 12 of lamp 18.Separating the demarcation strip 14a of refrigerating chamber 12 and refrigerating chamber 13 and the polylith shelf 14b of 13 inside, refrigerated chamber is transparent bodies made from synthetic resin, so the light of heat shield panel 19 reflections can shine all places of interior case 11a (in the refrigerator) by these shelves 14b and dividing plate 14a.
The whole surface of heat shield panel 19 is a matsurface, forms diffuse surface, with the light diffuse reflection of the lamp in the refrigerator 18 all places in the interior case 11a.The mean roughness (Ra) on heat shield panel 19 surfaces is 6.3 to 12.5.Its center line average roughness (Ra) is calculated the Ra that represents with micron by the JIS B0601 of Japanese Industrial Standards regulation according to following formula (1).
In the formula, f (x) is for being shown in the roughness curve of Fig. 5, the measured length of L for along centerline direction roughness curve being sampled.And f (x) is an X-axis with the center line of sampling part, is Y-axis with multiplying power longitudinally.
On the top of refrigerator internal pipeline 15, as shown in Figure 1, the lampshade 20 that covers lamp inside the box 18 and heat shield panel 19 is set.This lampshade 20 is a material with translucent synthetic resin, as shown in Figure 3, forms the heavy section 20a that wall thickness is done thickly in the middle.Thereby the light transmittance of lampshade 20 occupies a narrow space heavy section 20a's, and is local big at remaining.Also have, as shown in Figure 7, inclination pars convoluta 19b remembers respectively with the angle of lampshade 20 formations and makes θ L, θ R, and the relation of R=45 ° of θ L=θ is arranged.
In the upper end of lampshade 20, as shown in Figure 2, form the joint portion 20b of 2 claw-likes, form the joint portion 20c of 2 claw-likes in the bottom.Form 2 poroid joint 16c that bear joint portion 20b on the top of protuberance 16 again.Each joint portion 20b of lampshade 20 is combined with combined 16c of protuberance 16, and each joint portion 20c of lampshade 20 combines with the upper surface of refrigerator internal pipeline 15, and then lampshade 20 is contained on the pipeline 15.
According to the foregoing description, the door one of refrigerator main body is opened, and lamp inside the box 18 is promptly lighted, the direct directive lampshade 20 of a part of the light that this lamp penetrates.Curve shown in the dotted line of Fig. 6 represents, as shown in Figure 8, with uniform lamp inside the box cover 3 of wall thickness and reflecting plate configured in parallel, changes measuring point in regular turn, measures the measurement result that draws after the surperficial illumination that P orders simultaneously.From this curve as can be seen, under the situation of using the uniform lampshade 3 of wall thickness, lamp inside the box 1 front (L=0) and near illumination the most nearby is high, and along with the distance from lamp 1 becomes far away, illumination sharply reduces (reduction rate of illumination become far away along with the distance from lamp 1 and diminishing).
But under the situation of present embodiment, can regulate according to the distribution of supplying with light quantity at the light transmittance of lampshade 20 each several parts, therefore, the front of supplying with the many lamp inside the box 18 of light quantity the most nearby and near, the light quantity that sees through from lampshade 20 is inhibited.The solid line of Fig. 6 is to change the experimental result that surperficial illumination that the L pH-value determination pH P among Fig. 7 orders obtains in regular turn.From curve shown in the solid line of Fig. 6 as can be known, use lampshade 20 that lamp inside the box 18 fronts are inhibited with near illumination nearby.
Again, lamp inside the box 18 shines next residual light after heat shield panel reflection 19, directive lampshade 20.At this moment heat shield panel 19 is with the light diffuse reflection of lamp 18, and therefore, reverberation is along the facial 19b that tilts, and the inclination angle of 19b is shone to the both sides of lampshade 20 (part that light quantity is little).As a result, improved away from the part illumination of lamp 18, surperficial Illumination Distribution generally is even.When carrying out the mensuration of Fig. 6, used reflecting plate 4 and the heat shield panel 19 of surface as white.
Like this, by means of the accurate indirect lighting of using single light source, lamp inside the box cover 20 does not have light and shade difference ground uniformly light-emitting, and light from this lampshade 20 transmission in refrigerator, therefore, is shone in the refrigerator equably uniformly.Also because prevented that lampshade 20 spot shapes are luminous, when lamp inside the box 18 was in position higher in the refrigerator as the cooling type refrigerator of middle part, the light that lamp 18 penetrates can directly not enter user's eyes yet, has prevented the stimulation to eyes.
And the light that lamp 18 penetrates is by diffuse reflection, thereby there is no need to be provided with in refrigerator a plurality of lamps 18.Therefore, suppressed the increase of lamp inside the box number and wiring part number thereof and wiring process number.As a result, also suppressed the increase of cost.And lamp inside the box also there is no need to have used fluorescent lamp.
The wall thickness of suitably setting lampshade 20 can make the light transmittance of lampshade 20 reach desired value, and therefore, not needing to be provided with separately the light transmittance adjusting device just can the surperficial Illumination Distribution of careful adjusting.And can reduce cost.Moreover the central portion of the lampshade 20 corresponding with lamp inside the box 18 is done thickly, and the light quantity that sees through this part is suppressed.Thereby, can prevent also that from this respect the light of lamp 18 from directly entering user's eyes.Utilize again and block the heat shield panel 19 that heat that lamp 18 sends uses and constitute reflecting members.Therefore, there is no need to be provided with separately reflecting member, resultant costs is minimized.
And the dividing plate 14a and the shelf 14b that separate refrigerator inside are made of transparent material, thereby the light in the irradiation refrigerator arrives each corner in the refrigerator.Owing to use heat shield panel to make facial 19b, 19b, to lampshade 20, the light of lamp 18 is utilized the light of lamp 18 effectively by facial 19,19 reflections of tilting.
