  ADVANTAGE OF THE INVENTION According to this invention, the refrigerator provided with the automatic ice making apparatus which has a water supply tank with the ease of use in the case of mounting | wearing and an actual use state can be provided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a longitudinal sectional view of the refrigerator of the present embodiment. The refrigerator main body 1 has a refrigerator compartment 2, an ice making room 3 as a first freezer compartment, a second freezer compartment 4, and a vegetable compartment 5 from above. Although not shown in the drawing, the front opening of each of the storage chambers 2, 3, 4, and 5 is sealed by a door that can be opened and closed. In addition, a partition wall 6 is provided between the refrigerator compartment 2 and the ice making chamber 3 to partition and insulate both chambers. The partition wall 6 is thicker on the front side and the rear side is higher than the front side. The dimensions are thin. In other words, the thickness required to insulate between the refrigerator compartment 2 and the ice making chamber 3 has no problem with the thickness of the rear side, and the front side of the partition wall 6 is the refrigerator compartment door that seals the front of the refrigerator compartment 2. Are formed thicker than the rear surface side, so as to constitute a packing receiving surface and a packing receiving surface of the door that seals the front surface of the ice making chamber 3.

  For this reason, the partition wall 6 is provided with an inclined surface 6a connecting a thick part and a thin part of the vertical dimension as shown in the figure. This situation is the same in the refrigerator in which the vegetable room is arranged in the lower part of the refrigerator compartment 2. However, in that case, heat insulation is unnecessary between the refrigerator compartment and the vegetable compartment.

  An automatic ice making device is disposed in the ice making chamber 3 and includes a drive unit 7 that rotationally drives the ice tray 8 and an ice storage box 9 that receives the ice after ice making. The drive unit 7 and the ice tray 8 are located above the ice making chamber 3, and an ice storage box 9 is stored below them. When the ice making in the ice tray 8 is completed, the control unit (not shown) drives the drive unit 7 to rotate and deform the ice tray 8 so that the ice in the ice tray 8 is deiced and dropped, and the ice storage box 9 Stock in. It should be noted that a certain amount of water is automatically supplied into the ice making tray 8 after deicing by a water supply tank 10 described later, and ice making is performed again.

  A water supply tank 10 in which water to be supplied to the ice tray 8 is stocked is installed on a partition wall 6 that forms the bottom wall of the refrigerator compartment 2, and the water in the water supply tank 10 is stored at the refrigerator compartment temperature. It has become. A water supply pump 11 is disposed on the back side of the refrigerator compartment 2 to supply a set amount of water to the ice tray 8 by sucking up water in the water supply tank 10. As described above, this water supply is performed after the ice is removed from the ice tray 8.

  Further, the water supply pipe 12 is led out from the water supply tank 10 to the outside of the water supply tank 10, and the water in the water supply tank 10 is sucked up from the water supply tank 10 by the water supply pump 11. Is supplied to the ice tray 8. Therefore, one end of the water conduit 12 is near the bottom of the water supply tank 10 and the other end is led out of the water tank 10. With this configuration, the water sucked up from the water supply tank 10 is discharged from the discharge portion 12a which is the end of the water conduit 12 outside the water supply tank 10. The water discharged from the discharge part 12a reaches the ice tray 8 through the receiving part 11a located on the back side of the refrigerator compartment 2.

  In this embodiment, the connecting portion 13 is a detachable fit between the discharge portion 12a and the receiving portion (receiving tube) 11a. That is, by pushing the water supply tank 10 onto the back side of the bottom wall of the refrigerator compartment 2, the discharge section 12a is secretly fitted into the receiving tube 11a in one action and the refrigerator compartment 2 is fitted and fitted. The fitting is released by pulling the water supply tank 10 installed inside. In other words, the coupling portion 13 is detachably fitted with one action.

  Next, the water supply tank 10 will be described with reference to FIG. Drawing 2 is a figure which looked at water supply tank 10 of this example from the side wall side of a refrigerator. In the description, the directions of the back side (rear) and the front side (front) indicate directions in a state where the water supply tank 10 is installed in the refrigerator.

  As shown in these drawings, the water supply tank 10 of this embodiment includes a container 10a and a lid member 10b that covers the upper surface opening of the container 10a. The container 10a is provided with a water level line 10d (water label) that defines the amount of water that the user puts into the water supply tank 10. On the front side of the water supply tank 10, there is a handle 10 c used when the water supply tank 10 is taken in and out. The handle 10c only needs to be usable by the user with the container 10a covered by the lid member 10b, and there is no problem whether the handle 10c is provided on either the container 10a side or the lid member 10b side.

  Further, the back side of the container 10a is a bag-like portion 10e, and the bag-like portion 10e is covered by the container wall as well as the bottom surface and the back surface. A U-shaped groove is provided in the wall portion 10f extending upward from the upper surface wall of the bag-shaped portion 10e, and the lead-out tube 12 extends from the U-shaped groove to the back side of the refrigerator. That is, the outlet wall 10f having a U-shaped groove from which the discharge part 12a of the outlet pipe 12 is drawn is provided above the upper wall of the bag-like part 10e and on the front side of the bag-like part 10e. Yes. Therefore, the container 10a of the present embodiment is not opened on the entire upper surface, and the opening of the container 10a is formed including the upper end of the outlet wall 10f. The U-shaped groove will be described later.

  In the present embodiment, as shown in FIG. 2, the bag-like portion 10e is made to be pushed out from the outlet wall 10f and the opening is narrower than the outer periphery of the container 10a. The lower side is wider than the part. When such a container is made as an integral structure using a synthetic resin mold, the bag structure 10e cannot be made unless a slot is inserted. In order to make this insert piece forming easy, it is necessary to make the insert piece at the time of container forming into a tapered shape, and if it is not this shape, the operation becomes difficult.

  Therefore, in this embodiment, in order to facilitate the insertion and removal of the insert piece, the inclined surface 14 is formed at the bottom of the container 10a, and the container 10a is tapered. Therefore, the height of the inner bottom surface of the container 10a when the container 10a of the present embodiment is placed on a horizontal surface is higher on the back side than on the near side, and as described above, the bag-like portion 10e Since the upper and lower dimensions of the container 10a are provided, the rear side dimension is smaller than the front side dimension.

  Further, a shelf board 15 is installed in the refrigerator compartment 2, and food or the like stored in the refrigerator compartment 2 is placed on the shelf board 15. As shown in FIG. 3, the shelf plate 15 is provided at a size that prevents the water supply tank 10 from hitting the tip 15 a of the shelf plate 15 when the water supply tank 10 is inclined and stored.

  Next, the case where the water supply tank 10 is installed in the refrigerator compartment 2 is demonstrated using FIG. FIG. 3 is a diagram illustrating a state when the water supply tank 10 is incorporated into the refrigerator. In this embodiment, the water supply tank 10 is installed in a storage room between the shelf board 15 in the refrigerator compartment 2 and the partition wall 6.

  As mentioned above. A water level line 10d is clearly shown on the container 10a of the water supply tank 10, and the user usually puts tap water into the water supply tank 10 in a state where the water level line 10d is removed from the refrigerator compartment 2 using the line 10d as a guide.

  When the water supply tank 10 filled with water in accordance with the water level line 10d is to be installed in the storage room between the shelf board 15 and the partition wall 6, the water supply tank 10 is as shown in FIG. Tilted. At that time, the rear side projecting dimension of the bag-like portion 10e and the height of the upper surface wall are set so that the water surface L1 when inclined is not located above the lower end 17a of the U-shaped groove provided in the leading wall 10f. And the inclination 14 and the lead-out wall 10f and the U-shaped groove are set. In other words, the water level line 10d is moved up and down, or the volume of the bag-like portion 10e is set so that the water surface L1 does not go above the lower end 17a of the U-shaped groove. The water leakage prevention structure when the water supply tank 10 is installed will be described later.

  Next, the features of the refrigerator of the present embodiment will be described with reference to FIG. FIG. 4 is a diagram illustrating a state where the bottom surface of the refrigerator compartment is inclined and the water supply tank 10 is installed in the storage portion 16 having the inclined bottom surface. In this figure, each member with the same symbol as in FIGS. 1 to 3 shows the same thing.

  As shown in the figure, the water tank 10 is placed on the water tank mounting portion with the back side of the inclined surface 6a of the partition wall 6 as an inclined surface that is gentler than the inclined portion 6a and has a larger depth dimension of the inclined portion. The shape is such that it can be easily stored in the storage chamber 16. In accordance with the inclination of the water supply tank mounting portion, the bottom surface of the water supply tank 10 also has an inclined surface. Accordingly, since the water supply tank 10 is placed on the inclined surface of the partition wall 6, the water supply tank 10 itself is installed to be inclined in the refrigerator compartment 2.

  One of the reasons that the water supply tank 10 is inclined so that the back side is lowered is to match the inclination of the water supply tank mounting portion. In addition, the purpose of reducing the amount of remaining water in the water supply tank 10 is also provided. Have. Furthermore, it has the objective of making it easy to put the water supply tank 10 in the storage chamber 16.

  That is, when ice making in the ice tray 8 progresses and the water in the water supply tank 10 is sucked up through the water conduit 12, the water surface L3 as shown in FIG. 4 is finally obtained. At this time, if there is no inclined surface at the bottom of the water supply tank 10, the water remains uniformly at the bottom. In the present embodiment, even when the amount of water in the water supply tank 10 is reduced in this way, the remaining water is collected in the vicinity of the water conduit 12, so that the water in the water supply tank 10 can be effectively utilized as much as possible. Can do.

  In other words, by finally inclining the bottom surface of the water supply tank 10 and the upper surface of the partition wall 6 so that the portion where the water guide pipe 12 is located is the lowest part in the water supply tank 10, the finally remaining water is shown in FIG. Thus, the amount of unusable water remaining in the water supply tank 10 can be reduced.

  In the present embodiment, the slope 14 is required on the bottom surface of the container 10a for the reason described above as a manufacturing problem because the bag-like portion 10e is formed in the container 10a of the water supply tank 10. Therefore, by using the slope 14 on the inner bottom surface of the water supply tank 10, the height of the inner bottom surface of the water supply tank 10 is made lower at the end position of the water conduit 12 than the position in front of the container 10a. A rib 18 is provided at the bottom to maintain contact with the water supply tank mounting portion and to ensure stability when the water supply tank 10 is installed in the refrigerator compartment 2.

  Next, the relationship between the container 10a and the lid member 10b and the drawing out of the water conduit 12 will be described with reference to FIGS. 5 is a top view of the water supply tank 10 of the present embodiment, FIG. 6 is a cross-sectional view taken along the line AA in FIG. 5, and FIG. 7 is a cross-sectional view taken along the line BB in FIG.

  The lid member 10b is provided with a water inlet 19 so that new water can be poured into the water supply tank 10 without removing the lid member 10b from the container 10a. The water injection port 19 is provided with a lid 20. Further, the lid 20 is opened and closed by rotating by the shaft 20d. Further, the lid member 10 b is provided with an opening 21 serving as an air intake port through which air for replacing the water in the water supply tank 10 is supplied when water is supplied to the ice tray 8.

  In this way, by attaching the lid member 10b having the water inlet 19, the lid 20, and the opening 21 to the opening of the container 10a, the upper surface of the container 10a of the water supply tank 10 is closed. When this lid member 10b is attached to the container 10a, a concave groove formed by a pair of convex portions protruding further from the rear wall 22 of the U-shaped groove provided on the inner side of the lid member 10b. Then, after locking the flange 23 extending from the upper edge of the opening of the container 10a to the near side, the lid member 10b is turned to the lid closing side with the latching portion as a fulcrum, and the lid member 10b is moved to the near side. The provided locking projection 24 is rotated until it is locked in the locking recess 25 provided on the inner wall on the near side of the container 10a.

  Therefore, the inner wall 22 of the U-shaped groove is attached to the wall surface of the wall portion (leading wall) 10f extending upward from the upper surface wall of the bag-like portion 10e provided on the inner side of the container 10a and the lid member 10b. In such a state, it is preferable to adopt a configuration that is substantially parallel. Further, one end of the water conduit 12 is close to the bottom of the water supply tank 10, and the discharge portion 12a which is the other end is placed in a U-shaped groove 17 provided in the outlet wall 10f from above. The groove provided in the lead-out wall 10f is preferably a groove portion opened upward. However, the shapes of the U-shaped groove and the U-shaped groove are not limited to these. For example, even if the U-shaped groove 17 is a round hole, there is no problem as long as the workability is good.

  The outlet pipe 12 is provided with a water purifier 26. As shown in FIG. 7, the water purifier 26 is attached to the water supply tank 10 and contains chlorine, chlorine, etc. contained in the tap water in the container 10a. The water purification filter 26a received to remove the water is provided. The water sucked up from one end of the water conduit 12 is water that has passed through the water purifier 26, and this water is supplied to the ice tray.

  Thus, the water purifier 26 wider than the water conduit 12 is provided near the bottom surface of the water conduit 10 in the water supply tank 10. Therefore, the depth side end of the water purifier 26 has a structure in which the depth position is located on the back side of the opening of the water supply tank 10 and reaches the bag-shaped portion 10e.

  When the water conduit 12 to which the water purifier 26 is attached is removed from the container 10a together with the lid member 10b, the upper surface of the bag-like portion 10e in the container shape of the present embodiment in which the entire upper surface is not opened. When a structure is adopted in which the outlet tube 12 is attached and removed together with the lid member 10b by using a pivotal mounting with the upper edge on the back side of the opening as a fulcrum as described above, although the wall becomes an obstacle Even so, the lid member 10b can be easily opened and closed.

  As described above, the U-shaped groove 17 is provided in the outlet wall 10f provided to be connected to the bag-shaped portion 10e, and the discharge portion 12d that is one end of the L-shaped water conduit 12 passes through the U-shaped groove 17. Is extended outside the container 10a, and the other end is located at the bottom of the container 10a. Although the capacity of the water supply tank 10 is slightly reduced by the amount of the slope 14 that is required to make the bag-like portion 10e, the water supply tank 10 is inclined to form the partition wall 6 as shown in FIG. Residual water can be reduced as compared with the prior art by allowing the mounting portion 6b to be placed and the slope 14 portion being the lowest place when the water supply tank 10 is installed.

  Next, the relationship between the discharge part 12a of the L-shaped water conduit 12 and the U-shaped groove 17 will be described with reference to FIGS. 8 is a view taken in the direction of arrow P in FIG. 7, and FIG. 9 is a cross-sectional view taken along the line CC in FIG.

  When the water guide pipe 12 is attached to the container 10a, the discharge part 12a is attached to the U-shaped groove 17 of the container 10a so as to protrude rearward. The L-shaped water conduit 12 including the discharge portion 12a may be formed integrally with the lid member 10b, but is usually made separately due to a complicated mold. The separately formed L-shaped water conduit 12 and the lid member 10b are assembled together so as to be integrated. Therefore, removing the lid member 10b from the container 10a means that the L-shaped water guide pipe 12 is also removed from the container 10a. When the lid member 10b is attached to the container 10a, the discharge portion 12a is U-shaped. The lid member 10b cannot be attached to the container 10a unless it is stored in the groove 17.

  Since the members are assembled in this manner to form the water supply tank 10 of the present embodiment, it is not possible to keep a secret relationship between the discharge portion 12a and the U-shaped groove 17, and this portion is It must be removable. Therefore, since this part needs to be in a detachable contact relationship, complete integral molding cannot be performed.

  As shown in FIG. 3, when the water level line 10 d is protected by the user, when the water supply tank 10 is installed in the refrigerating chamber 2, it becomes the water surface L <b> 1, up to the lower end 17 a position of the U-shaped groove 17. The water surface reaches. However, if the user accidentally crosses the water level line 10d and injects water into the water supply tank 10, the water level will exceed the lower end 17a of the U-shaped groove 17, so that water leaks from this portion. It is necessary to devise so that there is no.

  Therefore, the U-shaped groove 17 is provided with a sealing material 27. This sealing material 26 seals the gap formed between the U-shaped groove 17 and the discharge part 12a, and keeps watertight. By using this sealing material 27, even when the water surface L1 shown in FIG. 3 rises to L2, for example, the water in the water supply tank 10 does not leak from between the discharge part 12a and the U-shaped groove 17. In addition, this L2 water surface is the center height of the discharge part 12a. Since the U-shaped groove 17 needs to have an opening that is equal to or larger than the outer diameter of the discharge part 12a, at least at the center height of the discharge part 12a, water tightness can be easily maintained.

  Thus, by providing the U-shaped groove 17 with the sealing material 27, it is not necessary to provide the sealing material on the outer periphery of the lid member 10b and the outer periphery of the opening of the container 10a. This is because the partition wall 6 on which the water supply tank 10 is placed has a large vertical dimension on the front side and a vertical dimension thinner on the rear side than the front side, and the water supply tank 10 is installed in the refrigerator compartment 2. In this case, as shown in FIG. 3, the water supply tank 10 is pushed into the back side while being inclined so that the back side of the water supply tank 10 is lowered. Therefore, when there is no water leakage position lower than the lower end 17a of the U-shaped groove 17 and water leaks, water always leaks from the U-shaped groove 17 to the back side, and the water surface reaches other positions. It has no structure.

  By adopting the refrigerator compartment structure and the water supply tank structure as described above, it is possible to prevent water leakage simply by disposing the sealing material 27 in the U-shaped groove 17, and it is not necessary to provide the sealing material over the entire opening.

  Here, with reference to FIG. 3 and FIG. 9, further explanation will be given on prevention of water leakage when the water supply bottle 10 is installed in the refrigerator compartment 2. As described above, the partition wall 6 on which the water supply tank 10 is placed has a vertical dimension that is thick on the front side, and a vertical dimension on the rear side that is thinner than the front side. An inclined portion 6a is provided between them, and a bottom surface portion of the bag-like portion 10e on the back side of the water supply tank 10 is also provided with an inclination 14, and the rib 18 is provided for the stability of the mounted state. At the bottom.

  In the present embodiment having the above-described configuration, the rib 18 is not extended to the back side wall surface of the container 10a (that is, the back side wall surface of the bag-like portion 10e), and the back end portion 18a of the rib 18 (see FIG. 9). Is extended to a midpoint position of the bag-like portion 10e. That is, the inner bottom surface of the bag-like portion 10e is an inclined surface whose back side is increased, and the outer bottom surface of the bag-like portion 10e is provided with ribs 18 extending back and forth from the near side to the far side. The end portion 18a was extended to the back side from the leading wall 10f and to the near side from the back side end portion 10e ′ of the bottom surface of the bag-like portion 10e.

  When installing the water supply tank 10 having such a configuration in the refrigerator compartment 2, as shown in FIG. 3, the bottom surface of the water supply tank 10 is brought into contact with the upper end of the inclined portion 6 a, A state in which the rear side end portion 10e ′ of the bottom surface of the bag-like portion 10e and the rear end portion 18a of the rib 18 are brought into contact with the water supply tank storage portion 16 will be described. That is, this state is a state in which the inclination angle of the water supply tank 10 is the largest when the normal water supply tank 10 is installed, and at this time, water is most likely to leak from the lower end 17 a of the U-shaped groove 17.

  The water level line 10d of the present embodiment is provided at a position lower than the upper surface wall of the bag-like portion 10e, and the partition wall is such that the water surface is L2 or less even at the inclination angle of the water supply tank 10 shown in FIG. 6. Since it is set as the structure of the water supply tank 10 and the shelf board 15, it has the structure which can prevent a water leak effectively, without providing a sealing material in the opening perimeter of the container 10a.

  However, even when the sealing material 26 is used, as shown in FIG. 8, the entire U-shaped groove 17 is not blocked, so that the L2 water surface (FIG. 3) when the water supply tank 10 is installed in the refrigerator. The above water injection is impossible. However, in order to make this possible, if the U-shaped groove 17 is changed to a round hole or the like and the sealing material 26 is interposed between the round hole and the discharge part 12a, the L2 water surface is still upward. It is possible to give. In this case, it is needless to say that the positional relationship of each part must be such that the discharge part 12a can be inserted into the round hole when the cover member 10b described above is attached.

  Since the present embodiment has the configuration as described above, the following effects can be expected. That is, in a refrigerator in which a water supply tank 10 is formed by a container 10a having an upper surface opened and a lid member 10b that covers the upper surface, and water in the water supply tank 10 is supplied to an ice tray 8 using a water supply pump 11. A bag-shaped portion 10e is formed on the front surface of 10a, leaving the outlet wall 10f of the discharge portion 12a of the water conduit 12 and projecting to the back side, and the discharge portion 12a of the substantially L-shaped water conduit 12 is extended from the outlet wall 10f. Since the water tank 10 is led out of the container 10a, even if the water tank 10 is slightly inclined when the water tank 10 is moved, the bag-shaped portion 10f absorbs the offset even if the water is displaced. Therefore, since it becomes the structure where water does not go easily to the joint part of the container 10a and the cover member 10b, a water leak can be prevented effectively. Further, the water supply tank 10 can be easily fitted to the pump 11 side receiving pipe 11a, and water leakage can be prevented without using a seal material or a lock material.

  Moreover, when installing the water supply tank 10 on the bottom face of the refrigerator compartment 2 using the inclination part 6a or level | step difference in which a back side becomes low, even if the water supply tank 10 inclines with a level | step difference or the inclination part 6a, it is determined to the water supply tank 10. By providing the container 10a with a bag-like portion 10e having a size so that the water in the water supply tank 10 does not spill out from the U-shaped groove 17 if the water is within the water level line, Water leakage can be prevented.

  Further, a U-shaped groove 17 is provided in the water guide wall 10f, and the discharge portion 12a of the water guide pipe is led out from the U-shaped groove 17 to the outside of the container 10a, and is attached to and detached from the pump-side receiving pipe 11a. Therefore, when the water supply tank 10 is pushed from the front side of the interior to be fitted with the pump-side receiving portion 11a, the fitting is possible regardless of the attachment state of the lid member 10b, so that a lock member is unnecessary. . Moreover, the discharge part 12a of the substantially L-shaped water conduit 12 attached to the lid member 10b is configured to be led out of the container 10a when the cover member 10b is attached, and the discharge part 12a of the water conduit 12 is U-shaped. Since the sealing material 27 for sealing is provided between the grooves 17, water does not leak from the water supply tank even when the water tank inclination angle is somewhat increased.

  In addition to this configuration, as shown in FIG. 9, the discharge portion 12a is provided at the same height as the uppermost surface of the lid member 10b or at a position lower than the uppermost surface. When the user pushes the water supply tank 10 so that the uppermost surface of the lid member 10b is below the tip 15a of the shelf board 15 with respect to the uppermost surface of the lid member 10b, the discharge unit 12a collides with other members. If it is a user with normal attention, the discharge part will not be damaged unless there is a particular problem. In addition, when the water supply tank 10 is placed at a position as shown in FIG. 3, the discharge portion 12a of the outlet pipe 12 is located on the back side from the tip 15a of the shelf board 15. It is only necessary to push the tank 10 into the back side, and there is no obstacle to the discharge part 12a, and a reliable installation is possible.

  Further, when the water supply tank 10 is pushed into the water supply tank storage part on the bottom wall of the refrigerator compartment 2, it is connected to the pump-side receiving tube 11a, and this connection is released when it is pulled to the near side from the water supply tank storage part. Therefore, the water supply tank 10 can be easily taken out.

  In addition, since the bottom surface of the refrigerator compartment 2 is an inclined surface, and the water supply tank 10 is installed on the bottom surface of the refrigerator compartment 2, water is collected on the bag-like portion 10e side. Not only can the water supply tank be mounted smoothly, but also by adopting a configuration in which the end of the outlet pipe 12 is positioned on the bag-like portion 10e side, the remaining water in the water supply tank 10 used for ice making can be reduced.
