Description

The present invention relates to a refrigerator.

Patent Document 1 discloses a detachable water supply tank 400 (0022).

JP-A-2009-287857

The water supply tank is connected to a water supply pump that draws up the water contained therein and transfers it to an ice making room or the like. If the water supply tank has a structure that can rattle for some reason, the water supply tank may also rattle when the water supply pump is attached or detached. At that time, the water supply tank tends to come into contact with the upper and lower bottom surfaces, the top surface, or the shelf due to the movement caused by rattling. This deteriorates the operability of the user's operation of attaching and detaching the water supply tank.

The present invention made in view of the above circumstances
A storage room with an open front and
A shelf arranged in the storage chamber and having a top surface support on the lower surface side,
The bottom under the shelf and
It has a water supply pump mounted on the bottom surface side.
The top surface support portion is a refrigerator that supports the top surface side of the water supply pump.

FIG. 2C cross-sectional view of FIG. Top perspective view of the water supply pump of the embodiment Partial sectional view of a portion where the water supply pump of the embodiment is fitted to the bottom surface of the refrigerator compartment.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a front perspective view of the refrigerator 1 of the present embodiment, and FIG. 2 is a front view of the refrigerator compartment 2 with the door of the refrigerator compartment 2 opened.
The refrigerator 1 includes a refrigerating room 2, an ice making room 3, an upper freezing room 4, a lower freezing room 5, a vegetable room 6, and the like, which form a storage room inside.
In the refrigerating room 2, a movable upper shelf 7, a fixed right side shelf 8, a movable left side shelf 9, a fixed lower shelf 10, and an indoor storage room 12 are arranged in this order from the top. On the upper surface of the lower shelf 10, a sill 11 extending vertically is arranged. A cooling panel 14 is provided on the back surface of the refrigerator compartment 2.

The right side shelf 8 and the left side shelf 9 are shelves whose left and right dimensions are smaller than those of the upper shelf 7, the right side shelf 8 is fixed in the refrigerator compartment 2, and the left side shelf 9 is movably provided. The other ends of the right side shelf 8 and the left side shelf 9 are supported by the upper ends of the vertical extension 11. The threshold 11 is fixed to the upper surface side of the fixed lower shelf 10.

[Lower shelf 10]
FIG. 3 is a top perspective view of the lower shelf 10, and FIG. 4 is a bottom view of the lower shelf 10.
The lower shelf 10 has a flat surface portion 19 made of glass or resin as a main surface, an upper surface bridging portion 26 extending in the front-rear direction arranged on the upper surface on the left and right center sides of the flat surface portion 19, and the periphery of the flat surface portion 19. A substantially rectangular frame portion 20 made of resin, for example, a resin frame portion 20 arranged on the edge of the lower shelf 10, a lower surface bridging portion 27 arranged on the lower surface, and a convex portion 25 continuous from the frame portion 20 on the lower surface side. It has a storage chamber support portion 28 that projects further downward from the lower surface bridging portion 27.
The flat surface portion 19 can be formed of a single plate-shaped member.
The upper surface bridging portion 26 has a bag-shaped portion 262 having an open rear end and closing the upper side near the front end and the front end, and has recesses 261 having walls erected on the left and right sides. The bridging portion 26 connects the frame member on the front side and the resin member on the back side with the glass plate 19 interposed therebetween.

The frame portion 20 is attached by so-called insert molding, which is formed around the flat surface portion 19 by supplying the fluidized resin before solidification to the edge of the flat surface portion 19. Preferably, as will be described later, the bridging portions 26, 27 and the convex portions 25 are also insert-molded in the same process as the frame portion 20.

The lower surface bridging portion 27 can realize stress relaxation of the flat surface portion 19. Similarly, since the upper surface bridging portion 26 is also made of resin that is insert-molded as an integral member at the same time as the frame portion 20, for example, stress can be applied to the upper surface side of the flat surface portion 19. Therefore, the lower surface of the flat surface portion 19 preferably includes or substantially coincides with the vertical projection region of the upper surface bridging portion 26, and has the lower surface bridging portion 27. As a result, the stress due to the shrinkage generated on the upper side and the lower side of the flat surface portion 19 is canceled out, and the warp of the shelf 10 is suppressed. Since the cutoff 11 is not attached to the lower surface bridging portion 27, unlike the upper surface bridging portion 26, it is not necessary to provide a concave portion or a bag-shaped portion.

A translucent structure, for example, paint can be applied to the flat surface portion 19, the lower surface bridging portion 27, and the frame portion 20. As a result, the wiring of the indoor storage chamber 12 and the water supply pump 16 is made difficult to see through the lower shelf 10. Since the paint may be scraped off when it comes into contact with a member arranged on the lower side of the shelf 10 such as the indoor storage chamber 12, a storage chamber support portion 28 is arranged as a spacer between the shelf 10 and the indoor storage chamber 12 and the like. There is. Since the storage chamber support portion 28 is arranged on the shelf 10 (for example, the frame portion 20 or the lower surface bridging portion 27) instead of the indoor storage chamber 12 or the like, the storage chamber support portion 28 comes into contact with the shelf 10 due to vibration during transportation or the like. The situation where the paint is scraped off is suppressed.

On the lower surface of the lower shelf 10, a convex portion 25 formed continuously from one side 201 of the frame portion 20 is arranged. Since one end 251 of the convex portion 25 is continuous with the frame portion 20, the frame portion 20 and the convex portion 25 can be easily formed in the same process.

The convex portion 25 (one end 251) may be formed discontinuously (that is, separated from) the frame portion 20. When both ends 251,252 of the convex portion 25 are continuously formed on the frame member 20 or the lower surface bridging portion 27, stress due to shrinkage is generated, and the flat surface portion 19, the frame portion 20, or the lower surface bridging portion 27 is deformed. There is a risk. Therefore, at most only one end 251 of the convex portion 25 is continuously integrated with the frame portion 20 and the lower surface bridging portion 27, and the remaining end portions 252 are separated from each other. As a result, the connection between the convex portion 25 and the frame portion 20 or the lower surface bridging portion 27 is interrupted. Since the generation of contraction stress can be suppressed by breaking the connection, the need to provide a structural member for canceling the stress on the upper part of the lower shelf 10 can be reduced, and the degree of freedom in design can be improved.

The convex portion 25 is provided in front of the water supply pump 16 as described later. As a result, the water supply pump 16 can be supported even if it is tilted forward, and the operability of the water supply tank 13 can be improved.

[Kiri 11]
FIG. 5 is a side view of the cutoff 11 of the present embodiment. The sill 11 includes a main surface 119, a narrow portion 112 arranged on the lower end side of the main surface 119 and sandwiched between the left and right side walls of the recess 261 and an acute-angled abutting portion 111 arranged at the front end of the narrow portion 112. , A notch 114 located on the upper end side to which the shelf 8 is attached. The right shelf 8 is provided with, for example, a groove (not shown) that fits in pairs with the notch 114.
The narrow portion 112 is inserted into the recess 261 and the abutting portion 111 abuts on the bag-shaped portion 262, the narrow portion 112 abuts on the left and right side walls of the recess 261, and the cutoff 11 is locked.

[Layout below shelf 10]
FIG. 6 is a diagram showing a lower layout of the lower shelf 10, and is a sectional view taken along line BB of FIG.
Under the lower shelf 10, the indoor storage chamber 12 and the water supply tank 13 are arranged side by side on the front side, surrounded on three sides by the U-shaped inner wall 21 of the refrigerator compartment 2, and the water supply pump 16 is on the rear side of the water supply tank 13. Is placed. The cooling panel 14 is attached to the inner wall 21 on the rear side.

The indoor storage room 12 is a box-shaped storage room that opens in the front and is provided in the refrigerating room 2, and is a storage room that can store food in an environment different from that of the refrigerating room 2. For example, when the temperature inside the refrigerating chamber 2 is about 2 ° C. to 10 ° C., a chilled chamber having a temperature of about -2 ° C. to 0 ° C. can be provided as an example of the indoor storage chamber 12.

The water supply tank 13 is a container for water that is a material for ice that is made and stored in the ice making chamber 3, and can be freely taken out by the user.
The water supply pump 16 is provided on the rear side of the water supply tank 13, and has a function of sucking up the water inside the water supply tank 13 and supplying it to the ice maker installed in the ice making chamber 3.
FIG. 7 is a diagram showing the arrangement of the water supply tank 13, the water supply pump 16, and the lower shelf 10, and is a cross-sectional view taken along the line CC of FIG. FIG. 8 is a top perspective view of the water supply pump 16, and FIG. 9 is a partial cross-sectional view of a portion where the water supply pump 16 is fitted to the bottom surface 24 of the refrigerator compartment.

[Mounting of pump 16 on bottom surface 24]
As illustrated in FIG. 9, a part of the bottom surface 24 of the refrigerating chamber protrudes upward corresponding to the attachment of the water supply pump 16. For example, a rear surface portion 241 and a front surface portion 242 are formed as an upward protruding portion of the bottom surface 24, and a recessed portion between them is provided on which the main portion of the water supply pump 16 is placed, and an ice making chamber below the refrigerating chamber. Etc. Further, a bottom surface fitting portion 243 is provided on the upper end side of the front surface portion 242.

The water supply pump 16 is a pump rear surface portion 161 located behind the rear surface portion 241 of the bottom surface 24, a pump front surface portion 162 located in front of the front surface portion 242 of the bottom surface 24, and a pump front surface portion 161 in a state of being attached to the refrigerating chamber. It has a pump fitting portion 163 arranged on the center side and corresponding to the bottom fitting portion 243.

To attach the water supply pump 16 to the bottom surface 24, the water supply pump 16 is carried so that the main part of the water supply pump 16 is placed between the protruding surfaces 241,242 of the bottom surface, and the water supply pump 16 is fitted to the pump fitting portion 163 and the bottom surface. The portions 243 are associated with each other to lock the two. In the state where both are locked, the front surfaces 162, 242 and the rear surfaces 161, 242 of the pump and the bottom surface face each other as described above. In the present embodiment, the pump fitting portion 163 is a claw and the bottom fitting portion 243 is a hole, but the mode and position are not limited as long as both are locked. By using the claw fitting, there are advantages such as easy assembly at the manufacturing site and reduction of tools used for repairs and the like.

[Rattling of pump 16]
Generally, a resin molded product has a draft of about 3 ° or less in order to improve mold release from the mold. In the present embodiment, the front and rear surfaces 161 and 162 of the pump have a draft so that the plate thickness becomes thinner from the upper part to the lower part. Further, at least the rear surface 241 (the side where the fitting portion is not arranged) of the bottom surface of the refrigerator has a draft so that the plate thickness becomes thinner from the lower part to the upper part.

As described above, if at least one of the pump 16 and the bottom surface 24 is made of resin, a gap is formed between the main portion of the water supply pump 16 and the front and rear sides of the bottom surface 24, so that the water supply pump 16 can be tilted back and forth. When the water supply pump 16 tilts back and forth, the top surface 164 of the pump 16 also tilts back and forth. Therefore, a convex portion 25 as a pump top surface support portion is provided on a portion of the lower surface of the shelf 10 facing the top surface 164 to support the inclination of the pump 16. At this time, a recess such as a slit may be provided on the top surface 164 so that the convex portion 25 can enter the concave portion, or a concave portion is formed instead of the convex portion 25 and the convex portion is extended from the pump top surface 164. May be good. Further, instead of the top surface 164, a convex portion may be extended from the shelf 10 so as to be in contact with and supported by the upper end side of the front surface of the pump 16.

The position of the convex portion 25 is not particularly limited as long as it can support the pump top surface 164, but the lower shelf 10 may bend due to the weight of stored items such as food. In this embodiment, as shown in FIG. 3, since there are walls on three sides of the frame member 20 excluding the front surface, the amount of deflection of the front portion is large. Therefore, since the front end side of the water supply pump 16 is more likely to come into contact with the shelf 10, the convex portion 25 may be arranged so as to be in contact with the front end side of the top surface of the water supply pump 16.

Similarly, by having the convex portion 25 at the lower part of the lower shelf 10 and behind the water supply pump 16, it is possible to prevent the water supply pump 16 from tilting to the rear side. Since the process of attaching the lower shelf 10, it is possible that the convex portion 25 collides with the water supply pump 16 when the lower shelf 10 is attached, resulting in improper installation. Therefore, it is desirable that the convex portion is provided only in front of the water supply pump 16. Further, in order to suppress tilting to the rear side, it is desirable to attach a cushioning material to the upper rear part of the water supply pump 16. Examples of the material of the cushioning material include materials having cushioning properties and rigidity such as foamed polyethylene and styrofoam blocks.
