Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a multi-door system,
The present invention relates to a refrigerator when the inside of the refrigerator (including a freezing compartment) is divided into several compartments, and particularly relates to a water supply path for supplying water from a water supply tank to an ice making section.

2. Description of the Related Art Refrigerators currently on the market include refrigerators for storing frozen foods, refrigerators for storing refrigerated foods, vegetables for storing vegetables and fruits, and chilled rooms for storing chilled foods. It is finely divided and each has its own partition wall and door.

On the other hand, when viewed from the manufacturing process of a refrigerator, for example, a cooler for cooling the inside of a refrigerator and a fan motor for circulating cool air for sending cool air cooled by the cooler to each room have been frozen from the inside of the refrigerator at the front. It is located near the back wall of the room.
Therefore, as mentioned above, when the interior of the refrigerator is divided into several chambers by the partition wall, it is immediately understood that the installation of the above-mentioned cooler and fan motor to the refrigerator body becomes very problematic. is there. In general, from this point of view, the front side of the freezing room with many built-in parts is large considering the installation from the front side of the inside of the refrigerator.

However, recently, a so-called "freezing room" which is conventionally located above the refrigerating room is installed below the refrigerating room.
Bottom freezer type refrigerating rooms have come to be marketed. Naturally, if this is the case, the freezing room will be of the drawer type (for convenience).
If the container has a deep bottom, it will be difficult to identify what is in the lower part, so the drawer type container must be a shallow bottom. Therefore, the container is divided into two or three. In this case, as described above, the frontage of the freezing room, which has conventionally been secured for assembling a cooler or the like, is partitioned by the partition wall. Therefore, the work efficiency at the time of assembling the refrigerator is significantly reduced. Further, in a refrigerator with an automatic ice making machine in which a water supply bottle part is installed in the refrigerating room and an ice making part is installed in the freezing room, there is a problem that it becomes difficult to process the water supply pipe connecting the water supply bottle part and the ice making part. .

As an example of a refrigerator having multiple doors, JP-A-60-111867 and JP-A-4-313665 can be cited.

[0006]

In the refrigerator in which the freezing compartment is located below the refrigerating compartment, and the partition wall is provided on the front surface of the freezing compartment, the refrigerator has two containers as follows. There was a problem.

(1) It becomes very difficult to assemble the cooler and the cool air circulation fan motor which are assembled to the back of the freezing compartment from the inside of the refrigerator.

(2) In a refrigerator of the type in which a cool air circulation fan motor is installed above the cooler, the position at which the cold air circulation fan motor is mounted is located above the partition wall forming the upper surface of the freezer compartment. Will end up.

(3) Even if a cooler is placed upright in the rear rear part of the freezer compartment and a cool air circulation fan is installed above it, the bottom of the freezer compartment is raised by the compressor as compared to the front side. , The size cannot be secured in the rear part of the freezer.

(4) The duct formation for guiding the cool air in the cooler chamber formed on the back wall of the freezing chamber to the refrigerating chamber located above the cooling chamber becomes complicated.

(5) In a so-called bottom freezer in which the freezing compartment is formed at the bottom, the usability of the ice made by the automatic ice making machine becomes a problem.

That is, the user must bend down to pull out the container containing ice. For this reason, it becomes necessary to install the automatic ice making machine as close to the freezing room ceiling (partition wall) as possible. At this time, the obstacle is the treatment of the water supply pipe for supplying water to the ice making section. Generally, as is well known, an ice tray attached to an automatic ice maker rotates about an axis of a drive motor. Therefore, it is necessary to install the water supply pipe at a place deviating from the rotation trajectory of the ice tray. Therefore,
Between the ice tray of the automatic ice making machine and the ceiling of the freezer compartment, at least the dimension of the rotation trajectory of the ice tray and the dimension of the water supply pipe installation portion are required.

Another object of the present invention is to minimize the size of the water supply pipe installation portion, to incorporate the water supply pipe into a refrigerator, and to reduce the cost of the water supply pipe portion.

[0014]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems.

That is, in a refrigerator with an automatic ice maker, which has a refrigerator compartment, a vegetable compartment, and a freezer compartment, which are arranged in this order from the top, and which has a water supply bottle section on the refrigerating compartment side and an ice making section on the freezing compartment side, the side wall of the vegetable compartment is The water supply pipe that passes through the guide groove provided in the heat insulating material is made to face the gutter provided on the partition wall that separates the freezer compartment from the vegetable compartment, and the water inlet provided in the gutter is located directly above the ice making part. It is formed to do.

Specifically, the gutter portion provided on the partition wall is integrally formed with the partition wall, and a heater for preventing freezing is provided on the gutter portion to remove the conventional aluminum pipe and the like, thereby greatly reducing the price reduction. It is a thing.

Further, the gutter portion is provided with a detachable lid to prevent the water supply path from being contaminated by dust or the like. Furthermore, the gutter is not made of resin, and the tip of the water injection port facing the ice making part has a protrusion size within 5 to 10 mm from the partition wall to improve the installation space of the ice making machine part. Furthermore, since the partition wall facing the water supply pipe is designed to be assembled to the refrigerator body after foaming, it is very easy to assemble the gutter, for example, to install the antifreezing heater. Is.

BEST MODE FOR CARRYING OUT THE INVENTION The details of the present invention will be described below with reference to an embodiment shown in the drawings.

FIG. 1 is a vertical cross-sectional view of a refrigerator equipped with the present invention, FIG. 2 is a view for explaining an assembled state of a partition wall equipped with the present invention, FIG. 3 is a cross-sectional view taken along line AA of FIG. 2, and FIG. Is BB in FIG.
FIG. 5 is a sectional view, FIG. 5 is a front view of the cooling chamber of FIG. 1, and FIG. 6 is a perspective view of a second partition wall different from FIG.

First, in FIG. 1, reference numeral 1 is a refrigerator main body, and this refrigerator main body 1 is a box body 5 in which a foam insulating material 4 is filled between an outer box 2 and an inner box 3, a compressor 6, a condenser 7, and a cooler. 8 and the like, a freezer compartment 9 formed by the box body 5, a vegetable compartment 10, and doors 12, 13, 14, 15 and the like for closing front opening portions of the refrigerating compartment 11 and the like.

The doors 12, 13, and 14 are provided in the freezer compartment 9.
a, 9b forming drawer containers 16, 17 and vegetable compartment 1
The drawer container 18 forming 0 is provided on the door side with a frame. In other words, the doors 12, 13, 14 are drawer-type doors, and the drawer containers 16, 17,
18 is drawn out. Further, the present refrigerator is also characterized in that the freezing compartment 9 is at the lowest stage, the center is the vegetable compartment 10 and the upper compartment is the refrigerating compartment 11. Then, the refrigerator body 1 has a compressor 6
For storage, the rear part of the freezer compartment 9 is made the upper bottom compared to the front part. Along with this, the drawer container 16 of the previous freezer compartment
Is made in a shape avoiding this part. Reference numeral 19 denotes a cooler room formed at the rear rear portion of the freezing room 9. This cooler room 1
The cooler 8 is vertically housed in the inside 9. Reference numeral 20 denotes a cool air circulation fan installed above the cooler 8. 21 is a fan motor. The cooler 8 and the cooling air circulation fan 20 are located on the back of the refrigerator body 1 as shown in FIG. Therefore, when the lower surface of the freezer compartment 9 is the upper bottom due to the compressor 6, the upper surface of the freezer compartment 9 (the partition wall
The lower surface of the cooling air circulation fan 20 is located above the lower surface. 22 is a partition wall as mentioned above. The partition wall 22 thermally partitions the space between the freezing room 9 and the vegetable room 10.
Further, the partition wall 22 has a rising portion 22a on the rear side. This rising amount is a height reaching the upper portion of the cooling air circulation fan 20. Further, the partition wall 22 forms the upper surface of the freezer compartment 9 as described above. In other words, the partition wall 22
Also forms the receiving surface of the gasket (not shown) of the doors 13 and 14. Therefore, at the front end of the partition wall 22, there is provided a high temperature pipe 24 (meaning a pipe of the condenser section of the refrigeration cycle) for heating the surface of the partition plate 23 to prevent dew. Based on the partition plate 23, the rising portion 22a is rising upward. Reference numeral 25 denotes a fan guard that also serves to partition the cooler chamber 19 and the freezer chamber 9. The cool air cooled by the cooler 8 is blown into the freezer chamber 9 through the fan guard 25 by the function of the cool air circulation fan 20. It is something. 26 is an automatic ice machine. The automatic ice making machine 26 is provided near the lower surface of the partition wall 22. Reference numeral 27 is a cold air duct for sending cold air to the above-mentioned automatic ice making machine 26, which is attached to the lower surface of the partition wall 22 as shown in the figure, and is attached to the lower surface of the partition wall 22 and the cold air duct 2
Between 7 is a cold air passage. Further, the upper partition wall 22 is divided into a side having a rising portion 22a (second partition wall 22c) and a side having a partition plate 23 (first partition wall 22b). Then, the first partition wall 22b is assembled to the box body 5 of the refrigerator before the foamed heat insulating material 4 is foamed. This is because the high temperature pipe 23 is attached to the back surface of the partition plate 23. That is, the high temperature pipe 23 is disposed on most of the front surface of the opening of the box body 5 of the refrigerator.
Is part of it. Therefore, it goes without saying that the first partition wall 22b may be a beam-shaped partition wall to which the high temperature pipe 23 can be attached. In addition, the first,
The second partition wall 22c is to be assembled to the box body 5 after foaming. That is, as shown in the figure, in the refrigerator in which the frontage of the freezing compartment 9 is divided into two by the third partition wall 28, the cooler 8, the cool air circulation fan 20 and the fan motor 21 described above are provided. It can be easily inferred that it is almost impossible to assemble through the partition wall 22 and the third partition wall 28 (within 30 cm) after foaming the heat insulating material 4. That is, the positions of the eyes of a person who incorporates the cooler 8 and the cool air circulation fan 20 into the box body 5 (refrigerator main body 1) are as shown in the figure. Therefore, in order to assist this work, the second partition wall 22c having the rising portion 22a and the first partition wall 22c
The partition wall 22b is configured to be assembled to the refrigerator body 1 when the assembly of the cooler 8 after foaming is completed. In other words, the size of the second partition wall 22c is such that the cooler 8 during service can be attached to and detached from the cooler chamber 19, and the cooler 8 and the like can be attached and detached. . 29 is a protruding wall. This protruding wall 29
The partition wall 22 (the rising portion 22a) described above forms an upper portion of the cooler chamber 19. A molded heat insulating material (styrofoam) 30 is provided in the protruding wall 29 before filling with the foamed heat insulating material 4, and is adhered and fixed by the foamed heat insulating material 4. Reference numeral 31 denotes a cool air passage formed through the formed heat insulating material 30 and the protruding wall 29. One side of the partition wall 22 described above is attached to the projecting wall 29 with the structure shown in the figure. Reference numeral 32 denotes a damper assembly. The damper assembly 32 is composed of an electric damper, which will be described later, and a heat insulating material having a cold air passage. Thus, the damper assembly 32 is assembled so as to be placed on the protruding wall 29, and the cold air passage formed in the damper assembly side heat insulating material just ahead communicates with the cold air passage 31 formed in the molded heat insulating material 30. ing. Therefore, the cold air from the inside of the cooling chamber 19 passing through the cooler 8 reaches the damper assembly 32 via the projecting wall 30, and only the required amount of cold air is produced by the damper.
It is to be supplied to the first grade. 18 is a drawer container for the vegetable compartment. As shown in the figure, this drawer container 18 for the vegetable compartment is
The projecting wall 29 and the rising portion 22a of the partition wall 22 are formed in a notched shape as much as they travel to the vegetable compartment 10 side.

It should be noted that, except for a special (double rail) drawer container provided in the refrigerator, such as the drawer container 18 for the vegetable compartment, the entire container 18 does not normally fly out of the refrigerator opening surface (partition plate 23 surface). Can only withdraw 2 / 3rd place. This is due to the structure of the frame 33 and the rail for drawing out the drawer container 18. Therefore, the drawer container 18 does not have to have such a depth that it comes into contact with the protruding wall 29 and the rising portion 22a. In other words, in the current refrigerator, the rear portion of the drawer container 18 is an ineffective space. The damper assembly 32 is installed to utilize this invalid space. Reference numeral 41 is a refrigerating compartment duct for supplying the cool air discharged from the damper assembly to the refrigerating compartment 11. Cold air is blown out from the duct 41 into the refrigerating compartment 11 as shown in the figure.

Next, the structure and mounting structure of the partition wall 22 will be described with reference to FIGS.
As described above, the partition wall is divided into the first partition wall 22b and the second partition wall 22c, and the connecting portion is configured as shown in FIGS. 2 and 4, and water, cold air, etc. from the seam can be prevented. It is designed so that it will not leak out. The connection between the second partition wall 22c and the inner box 3 is configured as shown in FIG. Although not shown in the drawing, the first partition wall 22b is mounted in a guide groove formed in the inner box 3 by sliding from the front surface thereof in a conventionally adopted manner.

Numeral 34 is a guide hole for screw tightening which is provided at both ends of the second partition wall 22c. Reference numeral 35 denotes a step formed on the side wall of the inner box 3 for attaching a partition wall. Utilizing this step 35, the second partition wall 22c is screwed to the second partition wall 22c. That is, the back part of the second partition wall 22c is attached to the projecting wall as shown in FIG.
The front part is attached to the first partition wall 22b as shown in FIG. As is apparent from the figure, the second partition wall 22c is mounted so as to cover it from the top when the cooler 8 and the cool air circulation fan 20 are completely assembled in the cooler chamber 19. . Needless to say, the step portion 35 that contacts the second partition wall 22c, the protruding wall 29, and the contact portion that contacts the first partition wall 22b are provided with a sealing material for preventing cold air and water leakage. Is natural.
As a means for facilitating the attachment of the sealing material, the second partition wall 22c is formed in a container shape as shown in FIG. 6, a flange 37 is provided on the end surface thereof, and a sealing material (for example, soft urethane foam or the like) is provided on the back surface of the flange 37. It is possible to attach it. Of course, at this time, it is needless to say that the inner box 3, the protruding wall 29, and the first partition wall 22b, which are the receiving surfaces, also need to correspond to each other.

Next, the relationship between the damper assembly 32 mounted on the upper surface of the protruding wall 29 and the cooler chamber 19 formed below the damper assembly 32 will be described with reference to FIG.

In the figure, 32 is a damper assembly, and this damper assembly 32 is an electric damper 38 and this damper 3
It is composed of a heat insulating material 39 for wrapping 8, and a case 40 and the like. Then, in the heat insulating material 39, the cool air received in the cool air passage 31 provided in the projecting wall 29 is guided to the electric damper 38 portion, and the cool air passing through the electric damper 38 reaches the refrigerating room duct 41 as shown by an arrow. A cool air passage 42 for guiding and a return duct 4 for guiding the return cool air of the refrigerating chamber 11 to the cooler 8.
5 has a cold air passage 43 connected to it. Reference numeral 47 is an electrical component box (for example, a substrate or the like is stored), which is incorporated in the previous case 40.

Next, the relationship between the cool air cooled by the cooler 8 and the damper assembly 32 will be described. In FIG. 5, among the cool air forcedly circulated by the cool air circulation fan 20, the cool air blown into the freezing chamber 9 is discharged through the discharge ports 48, 49.
The air is blown out to the freezing compartment 9 through the fan guard 25 (FIG. 1) and returns to the cooler 8 from the lower part of the fan guard 25. On the other hand, the cool air blown to the refrigerating compartment 11 side enters the cool air passage 42 on the duct assembly side through the cool air passage 31 formed in the projecting wall 29, and the amount of cold air controlled by the electric damper 38 changes to the refrigerating compartment duct. From 41, it is blown out into the refrigerator compartment 11 as shown in FIG. Further, the cold air after cooling the refrigerating chamber 11 passes through the cool air passage 43 provided in the damper assembly 32, and is projected to the inside of the cold storage so as to be continuous with the projecting wall 29. It is returned to the lower part of the cooler 8 through the return duct 45 provided in the. At this time, the vegetable compartment 10 is cooled by rotating a part or all of the cold air that has cooled the refrigerating compartment 11. The cool air after cooling the vegetable compartment 10 is returned to the cooler 8 side from the vegetable compartment cold air return port 46 provided in the return duct 45.

Next, the relationship between the high temperature pipe and the partition wall shown in FIG. 1 will be described with reference to FIG.

In the figure, 1 is a refrigerator main body, 2 is an outer box,
Reference numeral 3 is an inner box, 9 is a freezing compartment, 10 is a vegetable compartment, 11 is a refrigerating compartment, 24 is a high temperature pipe, and this high temperature pipe 24 is a heat radiation portion in the refrigeration cycle for preventing dew condensation. As described above, in the present invention, the first partition wall 22b and the second partition wall 22c shown in FIG. 1 are assembled after foaming and after being assembled in the cooler 8 to the freezer compartment or the like. In this way, the work of assembling the cooler 8 and the like in the freezer compartment 9 is facilitated. The problem here is the treatment of high temperature pipes. Usually, the high temperature pipe 24 is arranged on the back side (foam heat insulating material side) of the flange portion 2a of the outer box 2. In consideration of work separation, it is good that the high temperature pipe 24 is fixed to the partition walls at the time of foaming like the partition walls other than the partition wall 22, but the cooler 8 is provided in the inner part of the freezing chamber 9. In order to facilitate the assembling work, an L dimension of around 500 mm is required. Therefore, in the present invention, the dummy partition wall equivalent product 50 is used for the first partition wall 22b. That is, the dummy partition wall equivalent product 50 is the refrigerator body 1 when foaming.
After being foamed, it is removed from the refrigerator body as shown in FIG. 7 after foaming, so that the work of assembling the cooler 8 in the deep part of the freezing chamber 9 can be facilitated. In other words, some workers can bend the high temperature pipe to a position where it does not get in the way, if necessary. At the time when a series of work is completed, the high temperature pipe is assembled to the first partition wall as shown in the figure, and the high temperature pipe is assembled to the refrigerator main body. Of course, the second partition wall 22c is formed after the first partition wall 22b has been assembled. On the other hand, at the time of servicing (maintenance and inspection) of the refrigerator, the work can be sufficiently performed by removing the second partition wall 22c.

Next, referring to FIGS. 8 and 9, the automatic ice making machine 26 will be described.
Will be described.

FIG. 8 is a sectional view taken along the line CC of FIG. 1, and FIG. 9 is an enlarged view of the main parts of FIG. In the following figures, 26 is an automatic ice making machine. The automatic ice making machine 26 is attached to the partition wall 22. The automatic ice maker 26 is composed of an ice tray 26a, a drive unit and the like. As shown in the figure, the ice tray 26a
The ice tray part 26a is forcibly rotated by the drive part 26b.
The structure is such that the ice made in 2 is released. For this reason, a size capable of rotating the ice tray is secured between the ice tray portion 26a and the partition wall 22. 51
Is an ice storage box for temporarily stocking the ice made by the automatic ice maker 26. This ice storage box 51 is a drawer container 1
7. 52 is a water supply tank installed in the refrigerator compartment 11. Reference numeral 53 is a water supply pipe for guiding a fixed amount of water from the water supply tank 52 to the ice tray 26a. As shown in the figure, the water supply pipe 53 is detachably mounted in a guide groove 54 formed in the side wall (foam insulation 4) of the vegetable compartment 10a.

At this time, the water supply pipe 53 is detachably mounted in the guide groove 54. That is, the water supply pipe 53 is inserted through the opening 54a of the guide groove 54 into the guide groove 54 by utilizing the elastic deformation (a synthetic resin pipe) of the water supply pipe 53. Then, it is once pulled out into the vegetable compartment 10 through the opening 54b. The reason why the protrusion size of the water injection port 56 can be suppressed to 10 mm or less is as follows. That is, the dimension required to prevent the water flowing out of the water inlet 56 from wrapping around due to surface tension is about 10 mm. In the present invention, as shown in FIG. 9, the groove 62 of the partition wall 22 is secured in cooperation with the groove 62.

With the above-mentioned structure, first, the water supply pipe 53 and the guide groove 54 can be easily mounted. Moreover, since the water supply pipe 53 is located in the guide groove and is not in close contact with the foamed heat insulating material 4, the water supply pipe 53 can be easily pulled out at the time of maintenance and inspection. Next, since the water inlet 56 is located right above the ice tray 26a and the water inlet 56 is made of synthetic resin, it is accompanied by the antifreeze heater 57, but does not require grounding or the like. It is a thing. Further, the water supply pipe 53 and the gutter 55 can be associated with each other by freely absorbing an error depending on the size of the gutter 55.

Next, the water supply pipe 53 and the ice tray 26
Although it is the distance dimension between a, as described above, the necessary dimension for preventing the water sneaking around from the tip of the water supply pipe 53 due to surface tension is ensured by providing the groove portion 62 in the partition wall 22. , This point is not a problem. Since the size between the ice tray 26a and the partition wall 22 can be shortened, it is possible to install an efficient automatic ice maker, and of course, the usability of the resulting ice storage box is improved. Is.

Reference numeral 55 is a gutter integrally formed with the partition wall 22. The gutter 55 once receives the water supplied from the water supply tank 52 through the water supply pipe 53 and pours the water into the ice tray 26a of the automatic ice maker. Reference numeral 56 indicates the water injection port. As described above, the partition wall 22 is formed by filling a heat insulating material slab such as expanded polyethylene in an internal space formed by combining an upper partition and a lower partition, which are normally used separately in resin molding. It means that the gutter 55 can be made integrally with the upper partition. In other words, the water supply pipe 5
Reference numeral 3 denotes a pipe for guiding the water in the water supply tank 52 to the gutter 55, and the water injection port 56 of the gutter 55 pours water into the ice tray 26a. This pouring water 56 is located right above the ice tray 26a, and the protruding size from the partition wall 22 is suppressed to a very short value of 10 mm or less. One of the merits of allowing the water inlet 56 of the gutter 55 to face the ice tray portion 26a is that positioning is very easy. That is, the ice tray part 26a
This is also because the partition wall 22 is attached as a reference. In addition, the reason why the water inlet 56 is shortened to 10 mm or less, of course, the ice making machine 2
There is also a compact size of 6, but as mentioned earlier, gutter 5
Since 5 itself is not a metal but a synthetic resin, it may be vulnerable to freezing. In the present invention, as a countermeasure against this freezing, FIG.
As also shown in FIG. 3, a freeze prevention heater 57 is provided on the back side (heat insulating material side) of the gutter 55. The range that can be guaranteed by the antifreezing heater 57 is 10 mm or less. Usually, the determination as to whether or not the above guarantee can be made is determined by whether the remaining water film or water droplets in the water injection port 56 due to surface tension or the like will interfere with the next water injection.

The anti-freezing heater 57 may be energized when the refrigerator is turned on or continuously energized. The point is that it is sufficient if the previous judgment can be cleared.
Reference numeral 59 is a rising rib that prevents water spilled on the partition wall 22 from entering the gutter 55. The rising ribs 59 are provided on the periphery of the gutter 55. Reference numeral 60 is a cover that covers the upper surface of the gutter 55. The cover 60 is provided with a hole 61 for absorbing a dimensional error or the like appearing in the assembly of the water supply pipe 53.
It is detachably attached to the gutter 55.

Incidentally, one of the advantages of providing the gutter 55 with the cover 60 integrally with the partition wall 22 as described above is as follows. That is, as described above, the partition wall 22 is made of the upper partition material, the lower partition heating material, etc., and the above-mentioned components are put together as the partition wall 22 when the refrigerator is assembled. In other words, the antifreezing heater 57 used for the gutter 55 is naturally built in the partition wall 22 at this time. Therefore, the antifreezing heater 57 is very easy to work and is attached to the partition wall 22, and the interior of the partition wall 22 is relatively blessed in terms of space. Therefore, an antifreezing heater 57 having a capacity capable of sufficiently warming the gutter 55 can be provided in this portion.

[0038]

Since the present invention has the structure as described above, the maintenance and inspection can be easily performed as well as the arrangement of the water supply pipe. Further, since the water injection port facing the ice tray is made of a synthetic resin pipe and the protrusion size from the partition wall is defined, the installation efficiency of the automatic ice making machine is improved. Further, even if the antifreezing heater is installed near the water injection part, it does not require grounding as in the conventional case, so that it can be very advantageous in terms of cost reduction. Furthermore, since the installation place of the antifreezing heater is sufficiently secured, the required capacity can be secured.
