Description

  The present invention relates to a refrigerator, and more particularly to a refrigerator that illuminates a drawer-type storage room.

  Conventionally, as shown in Patent Document 1, a first storage room (refrigeration room) whose front is opened and closed by a pivoting door, and a lower part of the refrigerating room, which is drawn out by a pull-out door and its upper surface is opened and closed. In a refrigerator including a second storage chamber (freezer compartment), a light source is provided on the lower surface of the rotary door, and the interior of the freezer compartment is illuminated by the light source. And this refrigerator illuminates the freezer compartment pulled out with the drawer-type door in the state which the rotation-type door closed.

  However, in the refrigerator described above, since the light source is fixed to the lower surface of the rotary door, the area immediately below the light source in the freezer room becomes bright, but the area away from the light source becomes dark and poor visibility. There's a problem. For example, when the drawer door is fully opened, there is a problem that the drawer door side (that is, the front side) of the freezing room becomes dark.

  It is also possible to adjust the illumination area by adjusting the position of the light source by rotating the rotary door while the freezer is pulled out by the pull-out door. Since it is fixed to the type door, there is a problem that it is difficult to illuminate a desired part of the freezer.

  In the case of a refrigerator provided with a pair of pivot doors that rotate in double doors, the rotary door is a pair of rotary doors that rotate in double doors, and at least one of the pivot doors. It is desirable that the light source and the light source moving mechanism are provided on the lower surface of the door.

  In order to move the position of the light source to the optimum position according to the opening degree of the rotary door, an opening sensor for detecting the opening degree of the rotary door, and a control device for controlling the light source moving mechanism, It is preferable that the control device controls the light source moving mechanism in accordance with the opening obtained from the opening sensor, and the light source moving mechanism moves the position of the light source.

  In addition, in order for the position of the light source to be movable to an arbitrary position by the user, it is desirable that the light source moving mechanism is capable of manually moving the light source.

  Further, in order to illuminate a desired area of the second storage chamber without changing the direction of the light source itself, a reflector for reflecting the light of the light source to illuminate the lower part of the rotary door is provided, and the reflection is performed.

  An embodiment of the present invention will be described below with reference to the drawings.

  The refrigerator 100 according to the present embodiment is disposed below the first storage chamber 1 and the first storage chamber 1 whose front surface is opened and closed by a rotary door 11 as shown in FIGS. 1, 2, and 3. The second storage chamber 2 that is pulled out together with the pull-out door 21 and whose upper surface is opened and closed, the light source 3 that is, for example, an LED provided on the lower surface of the rotary door 11, the lower surface of the rotary door 11, and the light source And a light source moving mechanism 4 that linearly moves the light source 3 between the fixed end side and the free end side on the lower surface of the rotary door 11.

  The rotary door 11 according to the present embodiment includes a pair of rotary doors that rotate in a double door. The rotary door 11 has a concave portion 11M that opens downward in the lower portion of the door 11, and the light source 3 and the light source moving mechanism 4 are accommodated in the concave portion 11M.

  As shown in FIG. 4, the light source moving mechanism 4 moves the position of the light source 3 from the free end side to the fixed end side of the rotary door 11 according to the opening degree of the rotary door 11. And a rotation / linear motion conversion mechanism 41 that converts the rotation movement of the rotation type door 11 into a linear movement.

  Specifically, as shown in FIG. 5, the rotation / linear motion conversion mechanism 41 converts a rotation of the gear mechanism 42 into a linear motion and a gear mechanism 42 that rotates by the rotation of the rotation door 11. And a ball screw mechanism 43.

  The gear mechanism 42 is provided on the rotary shaft 12 of the rotary door 11 and transmits a rotary motion, and the rotary motion of the first gear member 421 is orthogonal to the rotary shaft 12. And a second gear member 422 having a helical gear, a bevel gear, or the like that is converted into a rotation shaft (a screw shaft of a ball screw described later in the present embodiment).

  The ball screw mechanism 43 includes a screw shaft 431 that rotates as the second gear member 422 of the gear mechanism 42 rotates, and advances and retreats along the axial direction of the screw shaft 431 as the screw shaft 431 rotates. And a moving nut member 432. The light source 3 is attached to the lower surface of the nut member 432. Thus, the position of the light source 3 is changed by the forward and backward movement of the nut member 432.

  In the refrigerator 100 of the present embodiment, as shown in FIG. 6 in particular, the cam mechanism 5 in which the light irradiation direction of the light source 3 is variable, and the guide surface 6 that guides the light irradiation direction of the light source 3 in the cam mechanism 5. And have.

  The cam mechanism 5 is constituted by the ball screw mechanism 43, and the light emission direction of the light source 3 is made variable by rotating the nut member 432 around the axial direction of the screw shaft 431 with respect to the screw shaft 431. ing.

  The guide surface 6 is a surface provided so as to contact the side surface 432a of the nut member 432 along the axial direction of the screw shaft 431. For example, the guide surface 6 is provided on the side wall of the concave portion 11M of the rotary door 11. The guide plate 6 may be constituted by a guide plate provided on the side wall of the concave portion 11M of the rotary door 11 or may be constituted by an inner surface of the side wall of the concave portion 11M of the rotary door 11.

  The guide surface 6 has a shape that is twisted so that the light irradiation direction of the light source 3 faces the center of the second storage chamber 2 from below as the light source 3 moves from the free end side to the fixed end side. That is, when the light source 3 is on the free end side, the guide surface 6 that contacts the side surface 432a of the nut member 432 is formed along the vertical direction. On the other hand, when the light source 3 is on the fixed end side, the guide surface 6 that contacts the side surface 432a of the nut member 432 has a light emission direction of the light source 3 facing inward (center side of the second storage chamber 2). Inclined.

  Next, the movement mode of the light source 3 by the light source moving mechanism 4 will be described.

  When the rotary door 11 is fully closed, as shown in FIG. 7, the position of the nut member 432 (light source 3) in the light source moving mechanism 4 is the free end side of the rotary door 11, that is, the second storage. This is the central portion in the width direction of the chamber 2. The light source 3 is turned on when the pull-out door 22 is pulled out and the second storage chamber 2 is opened.

  When the rotary door 11 is opened, the rotary motion of the rotary door 11 is transmitted to the ball screw mechanism 43 by the gear mechanism 42, and the screw shaft 431 rotates, whereby the nut member 432 (light source 3). ) Moves to the fixed end side of the rotary door 11. FIG. 8 shows a case where the rotary door 11 is opened 90 degrees. Furthermore, as shown in FIG. 9, when the rotary door 11 is fully opened, the nut 432 moves to the most fixed end side within the movable range on the lower surface of the rotary door 11. On the other hand, when the rotary door 11 is closed, the gear mechanism 42 and the ball screw mechanism 43 rotate in the reverse direction to the above, and as the opening degree of the rotary door 11 decreases, the nut member 432 (light source 3) It moves to the free end side of the pivotable door 11. In the present embodiment, the amount of movement of the nut member 432 (light source 3) is proportional to the opening of the rotary door 11. For example, when the opening degree of the rotary door 11 is half, the light source 3 is located at the center of the movable range on the lower surface of the rotary door 11.

  As the nut member 432 moves, the nut member 432 is guided by the guide surface 6 and rotates about the axial direction of the screw shaft 431. As shown in FIG. 9, the nut 44 (light source 3) is guided so that the light emission direction of the light source 3 faces downward when the position of the nut 44 (light source 3) is on the free end side of the rotary door 11, and from there the nut 44 (light source 3). The nut 44 (light source 3) is guided so that the light emission direction of the light source 3 faces the center of the second storage chamber 2 from below as it goes to the fixed end side.

  Next, the illumination method of the 2nd storage chamber 2 in the refrigerator 100 of this embodiment is demonstrated easily.

  When the user takes out the stored item from the second storage chamber 2 from the state in which both the rotary door 11 and the pull-out door 21 are closed, the user pulls out the pull-out door 21 and sets the second storage chamber 2 in the second storage chamber 2. Open the top surface. At this time, the light source 3 is turned on. And the position of the light source 3 by the accompanying light source moving mechanism 4 is adjusted by adjusting the opening degree of the rotary door 11, and the illumination area | region in the 2nd store room 2 is adjusted.

  According to the refrigerator 100 configured as described above, the light source moving mechanism 4 is provided between the lower surface of the rotary door 11 and the light source 3, so that the position of the light source 3 is determined by the opening degree of the rotary door 11. Since the position of the light source 3 relative to the rotary door 11 can be adjusted regardless of the opening, the desired position of the second storage chamber 2 can be illuminated. Thereby, the visibility of the 2nd storage room 2 can be improved.

The present invention is not limited to the above embodiment.
For example, an opening degree sensor that detects the opening degree of the rotary door 11 and a control device that controls the light source moving mechanism 4 are provided, and the control device is provided for the rotary door 11 obtained from the opening sensor. By adopting a configuration in which the light source moving mechanism 4 is controlled according to the opening, the position of the light source 3 can be moved to an optimal position according to the opening of the rotary door 11.

  Further, the light source moving mechanism may be configured to be able to move the light source manually.

  Further, by providing a reflecting plate that reflects the light from the light source 3 and illuminates the lower side of the rotary door 11, the reflecting direction of the reflecting plate can be changed according to the position of the light source 3 without providing the guide surface 6. Thus, the illumination area in the second storage chamber 2 may be variable. If it is this, the desired area | region of a 2nd storage chamber can be illuminated, without changing the direction of light source itself.

  Moreover, the irradiation range can be expanded by providing a diffusion plate for diffusing the irradiation light in the irradiation direction of the light source 3 to expand the irradiation range. In this case, it is conceivable that the diffusion plate is provided so as to close the opening of the recess 11M of the rotary door 11.

  In addition, it goes without saying that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
