Description

Refrigerator {Refrigerator}

The present invention relates to a refrigerator formed by adjoining an ice making room and a switching room between a freezing chamber and a vegetable room, and more particularly, to an insulating structure of an ice making room and a switching room.

In a conventional refrigerator, some ice making trays which make ice are exposed and arranged in a freezer compartment. In such a refrigerator, there is a problem in that the odor in the refrigerator is transferred to water to make a delicious ice in relation to the ice making time. In order to solve this problem, a refrigerator having an ice-making chamber independent of the freezer is considered to be installed adjacent to the switching chamber between the vegetable compartment and the freezer compartment and to speed up the ice making time.

Such a conventional technique is, for example, a technique disclosed in Japanese Utility Model Laid-Open No. 3-118485 (hereinafter, Prior Art 1).

In recent years, in order to further improve the convenience of use, it has been considered that the refrigerating chamber having the highest frequency of use among the plurality of storage chambers is disposed at the uppermost position, and the vegetable chamber and the freezing chamber are disposed below them. Moreover, in recent years, the refrigerator provided with the storage compartment (henceforth a switching compartment) which can switch the temperature in a storage compartment to several temperature, such as refrigeration, freezing, vegetable refrigeration, etc. according to a user's selection, is considered. As an example of such a prior art, there exist some described in Unexamined-Japanese-Patent No. 10-197129 (hereinafter, prior art 2).

In this prior art 2, a switching chamber is arrange | positioned in parallel with an ice-making chamber in the horizontal direction between a refrigerator compartment and a freezer compartment. In this prior art, a cooler is provided at the rear of the freezer compartment to advantageously cool the inside of the refrigerator.

By arranging the refrigerating chamber at the uppermost side, and the freezing chamber at the lowermost side and arranging the vegetable chamber at the position therebetween, a refrigerator having improved usability in using the vegetable compartment with a high frequency of use after the refrigerating chamber is considered. In the case where the switching room or the ice making room is provided in the refrigerator of such a form, the switching room and the ice making room are arranged in parallel in the horizontal direction and are disposed between the vegetable room and the freezing room without damaging the usability of the vegetable room. You can think of one form. In other words, in this form, the switching chamber is arranged directly above the lowermost freezing chamber.

In the case of the refrigerator of this structure, the cooler arrange | positioned in the refrigerator of the rear of a freezer compartment is provided in the upper position of the machine room formed below the refrigerator back side, and the height of a cooler upper end part is higher than the height position of the partition wall between a freezer compartment and a switching room. The high position, with the result that the coolers are arranged behind them in the form of both the freezer compartment and the changeover compartment. Alternatively, a cold air duct in which a fan and cold air flowing above the cooler flow into each storage chamber is arranged behind the switching chamber. In such a form, the switching room may be used as a refrigerating chamber or a vegetable chamber. Thus, a partition wall is provided between the cooler, the fan, the cold air duct and the switching chamber to suppress heat transfer between the two. And it is preferable that a heat insulating material is arrange | positioned at this partition wall. In addition, a heat insulating partition wall is provided between the adjacent storage rooms.

It is also preferable in view of cost and performance that the insulating partition wall forms an insulating wall integrally with the inner housing when forming the inner housing, and that the insulating material is filled when the insulating material is foamed. In the case where the duct is disposed, forming the insulating partition integrally with the inner housing increases the complexity of the inner housing and increases the cost.

In addition, integrally forming the partition wall between the switching chamber and the surrounding storage chamber with the inner housing complicates the flow path of the filling insulation and causes wrinkles or distortions on the inner housing surface, resulting in a lowered yield. In particular, when the parts for cooling the air in the refrigerator, for example, a fan for circulating the air cooled by the cooler or the cooler into the refrigerator, a cold air duct through which the cooled cool air passes, and the like, are avoided. If the partition wall is to be integrally formed with the inner housing, the shape becomes complicated and the manufacturing process increases, the yield decreases, or the manufacturing cost increases.

In order to solve this, it is easily conceivable that the insulating insulating wall forms the wall as a separate member, and then assembled in a predetermined position of the inner housing after foaming of the inner housing. However, the switching chamber requires a heat insulating partition wall between the upper and lower and adjacent storage chambers, and a cooling air passage such as a cooler, a fan, a duct, and the like in the switching chamber. As a result, the shape of the switching chamber becomes a shape of a housing having heat insulating partitions in the upper and lower sides. Integrating the insulating partition wall on the housing into the interior of the inner housing integrally reduces the working efficiency because there is not enough space for sealing or fixing the wall. In the said prior art, the advantage was not considered.

Therefore, it is conceivable that the insulating insulating film divides the wall into a plurality of members, and inserts each of the divided members into the inner housing. 10 illustrates a wall of the insulating partition of the refrigerator.

10, in the refrigerator in which the ice-making chamber 105 and the switching chamber 107 are formed adjacently between the freezing chamber 101 and the vegetable chamber 103, when using the switching chamber 107 as a refrigerator compartment, It becomes a structure which a heat insulation partition wall is provided in the surface which contact | connects 105 and the freezer compartment 101, respectively. In this case, the longitudinal insulating partition walls 109 of the switching chamber 107 and the ice-making chamber 105, and the transverse insulating partition walls (I) 111 of the switching chamber and the freezing chamber are made separately and are joined to the rear. have. Therefore, a gap often occurs in the junction portion 113 between the longitudinally insulating partition wall 109 and the transversely insulating partition wall (I) 111, and cool air and warm air leak from the gap, and condensation is formed on the switching room 107 side. (I) Freezing occurs on the freezing chamber 101 side.

In addition, when the switching chamber 107 is used as the freezing chamber 101, it becomes a structure in which the horizontal insulating partition wall (II) 115 is provided in the surface which contact | connects the vegetable chamber 103. As shown in FIG. This horizontal insulating partition wall (II) 115 has a structure which joins the horizontal insulating partition wall (III) 117 provided between the independent ice-making chamber 105 and the vegetable chamber 103. As shown in FIG. Therefore, a gap often occurs at the junction 119 between the transverse insulating partition wall (II) 115 and the transverse insulating partition wall (III) 117, and cold and warm air leak from the gap to form condensation and freezing. It happens.

And since there is a junction part in the said heat insulation membrane wall, when a heat insulation membrane fixes a wall in a predetermined | prescribed position, a problem arises that a right angle and a parallelism are hard to come out, and workability and sealing property deteriorate. Such a point is not considered in the said prior art.

An object of the present invention is to solve the above problems, to provide a refrigerator with good ease of use.

In other words, the present invention provides a refrigerator having good usability by realizing a heat insulating partition structure having low cold air leakage.

The flat heat insulating membrane is provided with a wall. By doing in this way, the fixed part is minimized and the leakage of cold and warm air is minimized.

Hereinafter, the present invention will be described in detail with reference to the embodiments shown in Figs. 1 is a front view of a refrigerator of the present invention, FIG. 2 is a longitudinal sectional view of FIG. 1, FIG. 3 is an enlarged view of a rear portion of a switching room of the refrigerator shown in FIG. 1, and FIG. 4 is a view showing a heat insulating partition wall of the present invention. Fig. 5 is a perspective view of the L-shaped insulating partition wall of the present invention, and Fig. 6 is a schematic diagram showing the structure of the insulating partition wall part of the refrigerator of the present invention.

In Fig. 1, reference numeral 1 denotes a refrigerating chamber, 3 a vegetable chamber, 5 an ice making chamber, 7 a switching chamber, and a switching chamber 7 is a room which can be switched to a temperature of a freezing chamber or a refrigerating chamber as needed. Reference numeral 9 is a freezer compartment. The switching chamber 7 is formed adjacent to the ice-making chamber 5 between the vegetable chamber 3 and the freezing chamber 9. In addition, as shown in FIG. 2, the switching chamber 7 blows cold air of the cooler 11 to the switching chamber 7 by the forced circulation fan 13, and the switching chamber 7 is cooled. Reference numeral 15 denotes a damper, and the damper 15 is disposed in a ventilation path between the forced circulation fan 13 and the switching chamber 7 to blow air into the switching chamber 7 by opening and closing the damper 15. It controls and controls the temperature of the switching room 7 to the temperature of a freezer compartment or a refrigerating compartment. Reference numeral 17 is a compressor.

As shown in Fig. 3, the present embodiment has a heat insulating partition between the vegetable chamber 3 and the switching chamber 7 and between the switching chamber 7 and the freezing chamber 9 at the front end side of the refrigerator in front of the wall. The partition plate 19 provided with the inside of the heating pipe 23 which is an anti-adhesion pipe is provided. This partition plate 19 has a H-shaped horizontal shape in this embodiment. The heat insulating material may be filled inside this partition plate 19.

In recent years, in order to improve the usability of a refrigerator, what has arrange | positioned the refrigerator room with the highest frequency of use among the several storage rooms of a refrigerator in the highest position, and provided the freezer compartment below this refrigerator compartment is sold. As an example of such a prior art, the Toshiba refrigerator GR-Y45KC machine is known. In this refrigerator, a plurality of storage compartments are formed therein, and these are arranged in the refrigerator compartment, the independent ice-making compartment and the switching chamber in the freezer compartment and the vegetable compartment in order from the top. That is, the freezer compartment is arrange | positioned at the lowest position in a vegetable compartment. The rear of the freezer compartment is generally installed to cool the air in the refrigerator, and a cooler that forms part of the refrigeration cycle is arranged. This is to more efficiently cool the freezing compartment, which is the lowest temperature storage compartment. Above the cooler, a fan for supplying air cooled by the cooler into the refrigerator is provided. This cooler is arranged below the wall with a heat insulating membrane partitioning the freezing chamber and the upper storage chamber (switching chamber).

In addition, by arranging the refrigerating chamber at the uppermost side, the freezing chamber at the lowermost side, and the vegetable compartment at the position between them, the refrigerator which improved the usability at the time of using a vegetable compartment with a high frequency of use after the refrigerating chamber is considered. . In the case where the switching room or the ice making room is provided in the refrigerator of such a form, the switching room and the ice making room are arranged in parallel in the horizontal direction, and are arranged between the vegetable room and the freezing room without damaging the usability of the vegetable room. You can think of forms. In other words, in this form, the switching chamber is arranged directly above the lowermost freezing chamber. In this case, the cooler disposed in the refrigerator at the rear of the freezer compartment is installed at a position above the machine chamber formed below the rear side of the refrigerator, and the height of the upper end of the cooler is higher than the height of the partition wall between the freezer compartment and the switching chamber. As a result, the coolers are arranged behind them in the form of both the freezer compartment and the changeover chamber. In addition, the cold air duct through which the fan and cold air which flow above the cooler flows into each storage chamber is arrange | positioned behind the switching chamber or the rear of a vegetable chamber.

In such a form, the switching room may be used as a refrigerating chamber or a vegetable chamber. Thus, a partition wall is provided between the cooler, the fan, the cold air duct and the switching chamber to suppress heat transfer between the two. And it is preferable that a heat insulating material is arrange | positioned at this partition wall. In addition, a heat insulating partition wall is provided between the adjacent storage rooms.

In view of cost and performance, it is preferable that this insulating partition wall forms the partition wall integrally with the inner housing at the time of forming the inner housing, and that the insulating material is filled in the foaming of the insulating material. In the case where a cooler, a fan, or a duct is arranged, forming an insulating partition integrally with the inner housing increases the complexity of the inner housing shape and increases the cost. In addition, the flow path of the filling insulating material becomes complicated, and wrinkles or distortions occur on the inner housing surface, resulting in a problem that the yield is lowered. Thus, the heat insulator is formed of a member separate from the inner housing and is attached inside the inner housing after foaming of the inner housing. At the time of this attachment, in consideration of workability and reliability and performance of the refrigerator, these partition walls are formed in a plurality, and assembled after foaming of the inner housing.

In the refrigerator, the end face of the front face side inside the heat insulation wall constituting the housing member of the refrigerator and the end face of the front face side of the compartment of each storage compartment inside and outside the refrigerator are connected to the door and the housing part of the refrigerator. In order to prevent dew condensation from the temperature difference, a pipe (hereinafter, an anti-dew pipe) which forms a part of a refrigeration cycle of the refrigerator and flows a refrigerant therein may be disposed. This dew attachment prevention pipe forms part of a refrigeration cycle, and since it is difficult to assemble and attach after foaming of the inner housing, the heat insulating wall and the membrane are assembled and attached to the inside of the member before foaming. Therefore, when the heat-insulating partition wall of the switching room is assembled after foaming, the work must be performed while avoiding the partition member in which the dew preventing pipe is disposed inside, so that the size of the space between the partition members and the space in the refrigerator are changed. The insulation barrier of the wall will be constrained in size. From this, the insulating partition wall of a switching room is divided | segmented into several, and is assembled and attached to the inside of a refrigerator.

Next, the structure of the partition plate and the partition frame of the present embodiment will be described with reference to the embodiments of FIGS. 4, 5, 6, and 7.

Reference numeral 221 denotes a flat heat insulating partition wall (first heat insulating partition wall), and the flat heat insulating partition wall 221 is a surface in contact with the ice making chamber 5 and the vegetable chamber 3, and a switching chamber 7 and a vegetable chamber. It is provided in the surface which contacts (3), and the whole structure has a flat plate-like structure without a junction part. Since the insulating partition wall is an integral structure without a junction as described above, the problem of the structure having a conventional junction is solved.

Reference numeral 223 denotes a fixed portion A, and the fixed portion A is a fixed position between the vertical type insulating wall of the L-shaped insulating partition wall 219 and the lower surface of the flat type insulating partition wall 221.

Fig. 6 is a schematic diagram showing the shape of the heat insulation partition wall in the refrigerator of the present invention, and is a view of the heat insulation partition wall viewed from the front side of the refrigerator. When the heat insulating partition wall around the switching room is assembled into the inner housing, it is necessary to divide the partition wall part.

In Fig. 6B, since the insulation portion between the wall portion of the insulation film wall is located above the wall portion of the insulation chamber and the ice making chamber, the cool air blown into the switching chamber leaks from the connection portion, or heat intrudes from the outside. It can further reduce.
