Description

  The present invention relates to a refrigerator provided with a drawer-type storage unit that can be drawn out to a storage room.

  A drawer-type storage unit used for this type of refrigerator generally has a door on the front side and a storage case as a storage unit on the rear side of the door via a support member. .

  By the way, in this kind of refrigerator, it is common to rely on the illumination of the room | chamber interior in which the refrigerator was installed as the illumination in the case of taking in / out a store with respect to a drawer-type storage part.

  For this reason, if the room where the refrigerator is installed is dark, even if there is room lighting, it is difficult for the lighting to reach the refrigerator, or the user stands in front of the refrigerator so that it is illuminated from behind the user. In such a case, there is a problem that it is difficult to see the inside of the storage case, and it is difficult to take in and out stored items. For example, when the indoor lighting is turned off at night, it is necessary to turn on the indoor lighting every time the stored item is taken in and out of the drawer-type storage unit.

  On the other hand, it is conceivable to install an illuminating lamp inside a storage room in which such a drawer-type storage unit is taken in and out. However, in the state where the drawer-type storage unit is pulled out, the storage case protrudes forward from the storage room, so that the interior of the storage case cannot be sufficiently illuminated by the illumination lamp installed in the storage room. There's a problem. In addition, when the storage room is a freezer room, the temperature conditions for the illuminating lamp are severe and reliability is low, and condensation is liable to occur, so it is necessary to consider the safety of electrical wiring. There are problems.

To provide a refrigerator that can.

In order to achieve the above object, the present invention provides a drawer-type storage unit that is provided so as to be able to be drawn out from the storage chamber of the refrigerator body, has a door on the front surface, and has a storage unit on the rear side of the door. in refrigerator having a rotation type door provided so as to be rotated through the hinge portion in the upper part of the door of the drawer-type storage unit, provided in the lower part of the door of the revolvable lamp A storage unit; an illumination unit disposed in the lamp storage unit; and a lamp shade attached to the lower side of the illumination unit, wherein the illumination unit is connected to the rotary door via the lamp shade. Illuminating the drawer-type storage unit below from the lower surface is characterized by the following.

  According to such means, the storage section can be illuminated by the illumination means existing above in the state in which the drawer type storage section is pulled out. Since the illumination means is installed at the lower part of the pivoting door located above the door of the drawer type storage unit, the storage unit is illuminated better than when the illumination unit is installed inside the storage room. It can be easily installed.

  A first embodiment of the present invention will be described below with reference to FIGS. First, in FIG.1 and FIG.2, although it is not shown in detail inside the refrigerator main body 1, the refrigerator compartment 2, the 1st freezer compartment 3, and the 2nd freezer which are each a storage room in order from the top. A chamber 4 and a vegetable chamber 5 are formed. Among these, the door 6 of the refrigerator compartment 2 located in the uppermost part becomes a rotation type rotated in the front-back direction via the hinge part 7 on the right side.

  On the other hand, in the first and second freezing compartments 3 and 4 and the vegetable compartment 5, drawer-type storage units 8, 9 and 10 are provided so as to be able to be drawn out. Each of the drawer-type storage units 8 to 10 includes doors 11, 12, 13 provided on the front surface, support members 14, 15, 16 provided at the rear of each door 11, 12, 13, and these support members 14. , 15, 16 and storage cases 17, 18, 19 serving as storage units detachably supported. When the doors 11, 12, and 13 are closed, the front surfaces of the doors 11 to 13 are substantially flush with each other as shown by the solid lines in FIG.

  Note that a gasket 20 with a magnet is provided on each of the doors 11 to 13 of the drawer-type storage units 8 to 10 and the peripheral portion on the inner surface side of the door 6 of the refrigerator compartment 2. The first freezer compartment 3 is provided with an automatic ice making device (not shown).

  A handle member 21 is provided on the lower front portion of the door 6 of the refrigerator compartment 2 so as to protrude forward. The handle member 21 is formed with a concave handle 22 on the left side in FIG. 2, and a lamp housing portion 23 is formed at a substantially central portion in the left-right direction as shown in FIG. A lamp 24 is provided as a means. For example, an incandescent lamp is used as the lamp 24. A reflector 25 that guides the light from the lamp 24 downward is attached to the lamp housing 23, and a lamp shade 26 is attached below the lamp 24.

  Here, the lamp | ramp 24 is arrange | positioned in the site | part which protruded ahead rather than the front surface of each said doors 11-13 in the state which closed the doors 11-13 of each said drawer | drawing-out type storage parts 8-10.

  A change-over switch 28 is provided on the right side of the handle member 21. The changeover switch 28 is configured to be switched in three stages as will be described later by, for example, sliding the operation unit 29 in the left-right direction. Lead wires 30 such as the changeover switch 28 and the lamp 24 are connected to wiring on the refrigerator main body 1 side via the hinge portion 7.

  Moreover, in the refrigerator main body 1, the door switch 31,32,33 (refer FIG.2 and FIG.4) is provided in the site | part corresponding to the doors 11-13 of each said drawer-type storage part 8-10. The door switches 31 to 33 are turned off when the doors 11 to 13 are closed, and turned on when the corresponding doors 11 to 13 are opened.

  FIG. 4 shows an electric circuit configuration of a portion related to the door switches 31 to 33, the changeover switch 28, and the lamp 24. In FIG. 4, the changeover switch 28 has a common contact c, a contact P1 for constantly turning off, a contact P2 for door activation, and a contact P3 for constantly turning on. Is connected to the bus. One end of the lamp 24 is connected to the other bus of the AC power source 35, and three door switches 31 to 33 are connected in parallel between the other end of the lamp 24 and the door responsive contact P2 of the changeover switch 28. ing. The always lighting contact P3 of the changeover switch 28 is connected to a common connection point between the lamp 24 and the door switches 31-33.

Next, the operation of the above configuration will be described.
First, as shown in FIG. 4, when the changeover switch 28 is switched to a state in which the common contact c and the door responsive contact P2 are connected, the doors 11 to 13 of the drawer type storage units 8 to 10 are closed. , The door switches 31 to 33 corresponding to the doors 11 to 13 are in the off state, and therefore the lamp 24 is in the off state.

  In this state, when the drawer-type storage unit 9 of the second freezer compartment 4 is pulled out of the drawer-type storage units 8 to 10, for example, as shown in FIG. 2 and the door 12 is opened, it corresponds to the door 12. The door switch 32 is turned on, and the lamp 24 is turned on accordingly. When the lamp 24 is turned on, the lower part is illuminated by the light (the illumination range is indicated by S in FIG. 1).

  At this time, since the lamp 24 is disposed at a portion protruding forward from the front surface of the door 11 of the upper drawer type storage unit 8, the lamp 24 is placed inside the storage case 18 of the drawer type storage unit 9 that has been drawn out. 24 can illuminate well from above. For this reason, even if the surroundings are dark (when the indoor lighting in which the refrigerator is installed is dark), the stored items can be easily taken in and out of the storage case 18.

  Even when the upper drawer-type storage unit 8 is pulled out or when the lowermost drawer-type storage unit 10 is pulled out, each of the storage cases 17, 19 is the same as when the above-described drawer-type storage unit 9 is pulled out. The interior can be well illuminated, and the stored items can be easily taken in and out of the storage cases 17 and 19.

  For example, in the state where the upper two drawer storage units 8 and 9 are pulled out at the same time, only the storage case 17 side of the upper drawer storage unit 8 can be illuminated. There is no problem because only the side can do it.

  On the other hand, when the changeover switch 28 is switched to a state in which the common contact c and the normally lit contact P3 are connected, the lamp 24 is always lit regardless of whether the doors 11 to 13 of the drawer type storage units 8 to 10 are opened or closed. Let it be in a state. Further, when the changeover switch 28 is switched to the state where the common contact c and the normally-off contact P1 are connected, the lamp 24 is always turned off regardless of the opening and closing of the doors 11 to 13 of the drawer type storage units 8 to 10. Let it be in a state.

According to the above embodiment, the following effects can be obtained.
In the state where one of the drawer-type storage units 8, 9, 10 is pulled out, the inside of the pulled-out storage case can be well illuminated by the lamp 24 existing above, so even if the surroundings are dark, The stored items can be easily taken in and out of the storage case, and the usability can be improved.

  Moreover, since the lamp 24 for illumination is provided in the handle member 21 of the rotation type door 6 in the refrigerator compartment 2 located in the uppermost part, compared with the case where an illumination means is installed in the inside of a store room. The storage case can be illuminated well, and wiring and installation are easy. In particular, since the lamps 24 are arranged at portions protruding from the doors 11 to 13, among the three-stage drawer-type storage units 8, 9, and 10, the inside of the storage case of the drawer-type storage unit that is pulled out is excellent. Can be illuminated.

  Since the lamp 24 is configured to be turned on and off in conjunction with the door switches 31 to 33 that respond to the opening and closing of the doors 11 to 13 of the drawer type storage units 8 to 10, the lamp 24 can be easily controlled. . Moreover, since the lamp | ramp 24 will light in the state where the doors 11-13 of the drawer | drawing-out type storage parts 8-10 are not closed reliably, what is called a half door (the doors 11-13 are not closed completely). State).

  In addition, by switching the changeover switch 28, the lamp 24 can be in a constantly lit state or a normally unlit state, and can be selectively used depending on the surrounding conditions. For example, when the lamp 24 is always lit, it can be used as a nighttime standing lamp. In a store, an advertisement 36 (see FIG. 2) or the like can be pasted on the front surface of the door 11, and the advertisement 36 can be illuminated by the lamp 24. In such a case, the display effect can be improved.

FIG. 5 shows a second embodiment, which is different from the first embodiment in the following points.
That is, for example, a phototransistor 40 as a light detection means is attached to the handle member 21 of the door 6 as shown by a two-dot chain line in FIG. 2, and the brightness around the refrigerator is set via the phototransistor 40. Detection is performed by the brightness detection circuit 41. A relay switch 42 is provided at one end of the lamp 24. When the brightness level detected by the brightness detection circuit 41 is darker than the predetermined brightness set in advance, the relay switch 42 is turned on via the drive circuit 43 so that the brightness level is lower than the predetermined brightness. When it is bright, the relay switch 42 is turned off.

  In such a configuration, it is possible to perform control such that the lamp 24 is not lit when the surrounding is bright and the lamp 24 is lit when the surrounding is dark.

FIG. 6 shows a third embodiment of the present invention. This third embodiment is different from the first embodiment described above in the following points.
That is, the lamp storage unit 45 is provided on the lower surface of the door 6 of the refrigerator compartment 2, and the lamp 24 is provided in the lamp storage unit 45. In such a configuration, the lamp 24 is disposed above the door 11 of the drawer type storage unit 8 in the upper stage, and the lamp 24 improves the inside of the storage case 17 of the drawer type storage unit 8. It becomes possible to illuminate.

The present invention is not limited to the above-described embodiment, and can be modified or expanded as follows.
The lamp 24 may be a fluorescent lamp.

  In addition, when the doors 11 to 13 are in a half-door state, the storage chamber is abnormally cooled, or the automatic ice making device needs to be supplied with water, the lamp 24 is blinked by, for example, a microcomputer (not shown). Thus, it is possible to provide a user with a function that makes it easy to understand the abnormality and actively informs the user of the abnormality.
