Description

  The present invention relates to a refrigerator.

  Modern refrigerators are generally of the type in which a refrigerated room, freezer room, and vegetable room are arranged from the top. In order to improve the visibility in the storage container of each storage room and improve usability, The thing which attached the illuminating device in the vegetable compartment is proposed (for example, refer patent document 1).

  Since the lighting device used in this type of refrigerator uses an incandescent bulb or the like as a light source, a large amount of heat is generated at the time of light emission, resulting in deterioration of cooling efficiency. Therefore, a light source using a semiconductor light-emitting element such as a light-emitting diode that generates little heat instead of an incandescent bulb has been proposed as a light source for the interior lighting device.

  Further, in Patent Document 2, although a lighting device in which a semiconductor light emitting element is applied to a drawer-type storage chamber has been proposed, a specific structure has not been proposed yet.

  On the other hand, there is a need for a space-saving and large-capacity refrigerator without enlarging the outer dimensions with bulk purchase of foods. Therefore, a lighting device for a refrigerator that contributes to a large space-saving capacity has become necessary.

JP-A-11-132650 Japanese Patent No. 4409414

  There are two main problems when arranging the lighting device in the drawer-type storage room. The first is the mounting structure and position of the lighting device, and the second is reliability.

  First, about a 1st subject, if an illuminating device becomes convex from the ceiling surface of a store room, food storage space will be reduced. The food storage space is reduced. That is, when the lighting device is more convex than the ceiling surface of the storage room, the portion from the convex portion to the back surface becomes an invalid food storage space.

  On the other hand, the storage container in the storage chamber is configured in a plurality of stages so that foods can be easily arranged. In this case, since the direction of irradiation is limited due to the properties of the semiconductor light emitting device, if there is food in the upper container, the illumination is blocked and the food in the lower container is difficult to see. Therefore, even when food is stored in a plurality of storage containers, a lighting device that reliably irradiates is required.

  Next, regarding the second problem, when a mounting substrate on which a semiconductor light emitting element is mounted is placed in a drawer-type vegetable room that is in a high humidity state, there is a possibility that electric corrosion may occur due to a short insulation distance between the contacts.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a refrigerator that has improved visibility in the storage container of a drawer-type storage room and improved usability.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  First, Embodiment 1 will be described with reference to FIGS. In FIG. 1, 1 is a refrigerator main body. The refrigerator main body 1 has a refrigerator compartment 2, an ice making chamber 4 provided on the left and right, an upper freezer compartment 5, a lower freezer compartment 6, and a vegetable compartment 7 in order from the top.

  Moreover, the door which opens and closes this front opening is provided in the front opening of each store room. That is, the front opening of the refrigerator compartment 2 is provided with a right refrigerator compartment door 2a and a left refrigerator compartment door 2b, and the ice compartment 4, the upper freezer compartment 5, the lower freezer compartment 6, and the vegetable compartment 7 have respective front openings. The ice making room door 4a, the upper freezing room door 5a, the lower freezing room door 6a, and the vegetable room door 7a are provided.

  The right refrigerator compartment door 2a and the left refrigerator compartment door 2b are rotatably supported by hinges (not shown) or the like provided on the upper part of the refrigerator main body 1, respectively. In other words, a so-called French door configured as a double-spread type is formed. The ice making room door 4a, the upper freezing room door 5a, the lower freezing room door 6a, and the vegetable room door 7a are each a drawer-type door and can be pulled out together with the storage containers of the respective storage rooms.

  In FIG. 4, although not shown, the cool air is circulated on the back side of the refrigerator main body 1 by a cooler, an internal fan, and a duct, and each storage chamber is controlled to be cooled to a predetermined set temperature. The compressor 8 that supplies the refrigerant to the cooler is disposed in the machine room 8 a at the lower back of the refrigerator body 1.

  A pair of left and right drawer frames 19 extending from the inside of the door to the back side are attached to the vegetable compartment door 7a to hold a vegetable compartment lower container 25 (storage container). The drawer frame 19 slides on a rail formed on the side wall of the vegetable compartment 7, and as shown in FIG. 4, the vegetable compartment lower container 25 together with the vegetable compartment door 7a is pulled out to the outside. ing. Note that other drawer type doors have the same structure.

  In the refrigerator configured as described above, the lower freezer compartment 6 and the vegetable compartment 7 are partitioned by a partition 10b. The partition 10b is comprised by the resin molded product provided with the partition recessed part 11b, and the partition heat insulating material 12 of the inside. The partition recess 11b is provided closer to the center front. The partition heat insulating material 12 is made of urethane foam or polystyrene foam, and is a heat insulating material that partitions a freezing temperature zone (about −20 ° C.) and a vegetable room temperature zone (about 3 ° C.). In this case, it is desirable to use urethane foam having good heat insulation performance.

  The illumination device 30b is attached to the partition recess 11b provided near the center front by an appropriate locking means such as a screw. A door switch is attached to the partition 10b. The door switch detects the open / close state of the vegetable compartment door 7a, and the lighting device 30b is lit to illuminate the vegetable compartment lower container 25 with the door open. It has become.

  Next, the details around the illumination device 30b will be described with reference to FIG. The illumination device 30b includes a mounting substrate 31 on which a plurality of semiconductor light emitting elements 32 that emit light having a wavelength in the visible light region are mounted, and a transparent resin lamp cover 33. The mounting board 31 is connected to a control board (not shown) provided in the refrigerator body 1 by a connector 35. At this time, the transparent resin lamp cover 33 is configured not to protrude more than the ceiling surface 36b of the vegetable compartment 7 (lower part of the partition 10b).

  A sealing material 34 is provided between the outer peripheral flange portion of the transparent resin lamp cover 33 and the partition recess. This is a sealing material 34 provided to shield the interior of the lighting device 30b and the vegetable compartment 7 serving as a storage room, and shields moisture and prevents the surface of the mounting substrate 31 from being exposed. The material may be O-ring or polyethylene foam as long as moisture can be shielded.

  The necessity of the sealing material 34 will be described with reference to FIG. FIG. 4 shows a condition where the temperature of the vegetable compartment is 2.68 ° C. and the temperature of the freezer compartment is −19.7 ° C. The dew point temperatures at%, 85%, and 90% are plotted.

  If dew is generated on the surface of the mounting substrate 31, the insulation distance between the contacts is short, so that electric corrosion may occur, leading to failure. Therefore, in order to prevent dew, it is desirable to ensure a heat insulation thickness. However, it is known that when a leafy material with a high water content is stored in the vegetable room 7, the humidity reaches 90% or higher. Even if the urethane foam which is the performance is used, a heat insulation thickness of 30 mm or more (corresponding to the d1 dimension in FIG. 5) is required. Furthermore, the height of the lighting device 30b is still required to be about 15 mm (corresponding to the dimension d2 in FIG. 5) even if the semiconductor light emitting element 32 capable of saving space is used, and generally requires a heat insulation thickness of 45 mm or more. And

  Increasing the heat insulation thickness more than necessary is not preferable at present when a large capacity is required. Therefore, in order to prevent the mounting substrate 31 from being exposed in the current heat insulation thickness, a sealing material 34 is provided between the outer peripheral flange portion of the transparent resin lamp cover 33 and the partition recess. In addition, the sealing material 34 can ensure the reliability of the connector 35 provided in the lighting device 30.

  Further, as shown in FIG. 3, the mounting substrate 31 on which a plurality of semiconductor light emitting elements 32 are mounted is attached to the front portion in the front-rear direction with the optical axis inclined at an angle φ1. The relationship of the inclination angle φ1 will be described with reference to FIG. FIG. 5 is a longitudinal sectional view illustrating an illumination range by the illumination device 30b in FIG. FIG. 5 shows a state when the vegetable compartment door 7a is pulled out to the maximum (drawing amount L1) and opened. The storage container of the vegetable room 7 is composed of a vegetable room upper container 24 and a vegetable room lower container 25.

  In FIG. 5, the light distribution angle of the semiconductor light emitting element 32 (with a range of 50% or more of the maximum light amount in the irradiation range of the semiconductor light emitting element 32) is θ1, and the optical axis of the mounting substrate 31 is not tilted. Illumination ranges are described for the case where the optical axis is installed vertically and the case where the optical axis is installed at an angle φ1 toward the front in the front-rear direction. In the present embodiment, the illumination device 30b (semiconductor light emitting element 32) is disposed in the recess 11b at an angle φ1. Therefore, it has the relationship which can illuminate to the near flange part 24a of the vegetable room upper stage container 24. FIG.

  Here, if an example of each dimension is given, for example, the amount of extraction L1 is 425 mm, the light distribution angle θ1 is 120 °, the height H1 from the bottom of the vegetable compartment lower container 25 to the front flange portion 24a of the vegetable compartment upper container 24 Is 265 mm, the inclination angle φ1 is 26 °.

  In the present embodiment, the center of the optical axis is positioned on the front side of the rear wall of the vegetable room lower container 25 in the pulled out state. Thereby, the inside of the storage container (The vegetable room upper stage container 24, the vegetable room lower stage container 25) of the pulled-out state can be illuminated appropriately.

  FIG. 6: shows the top view of the vegetable room which concerns on Embodiment 1 of this invention. By arranging a plurality of semiconductor light emitting elements 32 in the horizontal direction, the illumination range in the storage container (the vegetable room upper container 24, the vegetable room lower container 25) is expanded. As an example, if the light distribution angle θ1 of the semiconductor light emitting element 32 is 120 °, the height from the bottom of the vegetable room lower container 25 to the lighting device 30 is 290 mm, and the width of the vegetable room lower container is 608 mm, the semiconductor By setting the pitch dimension between the light emitting elements 32 and 68 to 68 mm, it becomes possible to illuminate the inside of the lower compartment 25 of the vegetable room without left-right unevenness.

  Next, Embodiment 2 will be described with reference to FIGS. 2 and 7 to 9. First, referring to FIG. 2, an implementation when the lighting device 30 a is applied in the lower freezer compartment 6 will be described below. The upper freezer compartment 5 and the lower freezer compartment 6 are in the same freezing temperature zone. The partition 10a is disposed only in the front part and constitutes a part of the surface for receiving the sealing material 34 of the ice making room door 4a, the upper freezer compartment door 5a, and the lower freezer compartment door 6a. That is, since the temperature zone is common, the rear of the partition 10a communicates and is positioned forward to receive each door. The partition 10a includes a partition heat insulating material 12a inside, and a lighting device 30a is attached to the partition recess 11a at the rear of the partition heat insulating material 12a by appropriate locking means such as screws. Then, the open / close state of the lower freezer compartment door 6a is detected by a door switch attached to the partition 10a, and the lighting device 30a is turned on when the door is open. The interior of the room inner stage container 22 and the lower stage freezing room lower container 23) is illuminated.

  A pair of left and right drawer frames 18 extending from the inside of the door to the back side are attached to the lower freezer compartment door 6a to hold the lower freezer compartment lower container 23 (storage container). As shown in FIG. 4, the drawer frame 18 slides on a rail formed on the side wall of the lower freezer compartment 6 so that the lower freezer compartment lower container 23 is pulled out together with the lower freezer compartment door 6a. It is like that. Note that other drawer type doors have the same structure.

  Further, a sealing material 34 is provided between the outer peripheral flange portion of the transparent resin lamp cover 33 and the partition recess. This is a sealing material provided to shield the inside of the lighting device 30b and the lower freezing room 6 which is a storage room. Since the mounting substrate 31 is cooled close to the freezing temperature zone (about −20 ° C.), when the lower freezer compartment door 6a is opened and closed, if there is a large amount of moisture outside the cabinet, the surface of the mounting substrate 31 is exposed. This is for the purpose of preventing the occurrence of. Although not shown, it goes without saying that the cord outlet in the partition recess 11a is also shielded. Further, as described above, the sealing material 34 may be an O-ring or polyethylene foam as long as moisture can be shielded.

The relationship of the inclination angle φ2 will be described with reference to FIG. FIG. 8 is a longitudinal sectional view illustrating an illumination range by the illumination device in FIG. The storage container of the lower freezer compartment 6 includes a lower freezer compartment upper container 21, a lower freezer compartment middle container 22, and a lower freezer compartment upper container 23. FIG. 8 shows a state where the lower freezer compartment door 6a is pulled out to the maximum extent (drawing amount L2) and opened. This configuration is a structure in which the lower freezer compartment middle container 22 is also drawn out in synchronization with the drawer of the lower freezer compartment door 6a.

Illumination ranges are described for the case where the optical axis is installed at the front and the front side in the front-rear direction and the optical axis is inclined at an angle φ2. At this time, the relationship is such that the front flange portion 24 of the middle compartment of the freezer compartment can be illuminated.

  Here, if an example of each dimension is given, for example, the drawing amount L2 is 405 mm, the light distribution angle θ2 is 120 °, and the height between the bottom surface of the lower freezer compartment lower container 23 and the front flange portion 22a of the lower freezer compartment middle container 22 is high. If the height H2 is 207 mm, the inclination angle φ2 is 18 °.

  In the present embodiment, the center of the optical axis is located on the front side of the rear wall of the lower container 23 of the lower freezer compartment in the pulled out state. Thereby, the inside of the storage container (the lower freezer compartment upper container 21, the lower freezer compartment middle container 22, the lower freezer compartment upper container 23) in the pulled-out state can be appropriately illuminated.

  In FIG. 11, the top view of the lower stage freezer compartment which concerns on Embodiment 2 of this invention was shown. By arranging a plurality of semiconductor light emitting elements 32 in the horizontal direction, the illumination range in the storage container is expanded.

  Here, as an example, the light distribution angle θ2 of the conductor light emitting element 32 is 120 °, the height between the bottom surface of the lower freezer compartment lower container 23 and the lighting device 30 is 290 mm, and the horizontal width of the lower freezer compartment lower container is 601 mm. For example, by setting the pitch dimension between the semiconductor light emitting elements 32 to 68 mm, it is possible to illuminate the inside of the lower container 23 of the lower freezer compartment without left-right unevenness.

  In this embodiment, most of the irradiation ranges overlap in the left-right direction. Thereby, while having a plurality of optical axes of the semiconductor light emitting elements 32, 32, the directivity is eased and the visibility can be improved.
