Description

[Detailed Description of the Invention] G) Industrial Application Field The present invention relates to a refrigerator, and particularly to a refrigerator in which the inside of the refrigerator is divided into two parts by a partition wall.
The system is divided into chambers, and each chamber is equipped with a refrigeration system evaporator, and the upper machine room of the main body is equipped with a condensing unit that together with each evaporator constitutes two independent refrigeration systems. This article relates to a refrigerator consisting of:

(c4 Conventional technology) Conventionally, a general method of arranging a partition wall in a refrigerator to divide it into a freezer compartment and a refrigerator compartment and cooling each compartment is disclosed, for example, in Japanese Patent Publication No. 58-51180. As shown in FIG.

Since such a cooling method is a one-system refrigeration system, temperature control of the refrigerator compartment in particular is complicated, and furthermore, if the refrigerator breaks down, both the freezer compartment and the refrigerator compartment will be insufficiently cooled.

Therefore, it is preferable to consider a method of configuring two independent division systems and cooling the freezer compartment and the refrigerator compartment independently.

Problems to be Solved by the Invention However, when configuring two independent refrigeration systems, it is especially difficult to install condensing units in parallel in the upper machine room of the main body.
It requires a large installation space, the condensing unit alone increases the overall size, and it is difficult to use it only in large refrigerators.

Therefore, the present invention further improves this technology and configures two independent refrigeration systems, but each condensing unit installed in the machine room, specifically the condenser of the condensing unit, The aim is to reduce the installation space by improving the installation structure.

B) Means for solving the problem The present invention divides the inside of the refrigerator into two rooms by a partition wall,
A refrigerator in which an evaporator is installed in each chamber, and a condensing unit that constitutes an independent 2-system refrigeration system together with each evaporator is installed in the machine room at the top of the main body, the condensing unit Each of the condensers is composed of a plurality of fins, a refrigerant pipe perpendicular to the fins, and a pair of left and right tube plates that support both ends of the refrigerant tube, and the upper ends of both tube plates of one condenser are The lower ends of both tube sheets of the other condenser are respectively bent outward, and the lower end bent portions of both tube sheets of the other condenser are placed on the upper bent portions of both tube sheets of one condenser. This is a refrigerator that solves the problems of the prior art by screwing the two together.

Four functions According to the above configuration, the condenser of one condensing unit is placed above the condenser of the other condensing unit, and the condensers can be configured and installed in two stacked layers.

(f) Embodiment Figure 1 is a perspective view of the main parts of the refrigerator of the present invention, and Figure 2 is the same (
3 is a schematic front view showing the internal structure of the refrigerator of the present invention, and FIG. 4 is a refrigerant circuit diagram of the present invention. (1) is the refrigerator main body with a heat-insulating structure; The interior is divided into a freezer compartment (3) and a refrigerator compartment (4) by a partition wall (2).

As shown in FIG. 4, the present invention provides an electric compressor (5
), a condenser (6), a first refrigeration system (9) for the freezer compartment in which a cavillary chain (power and an evaporator (8) as a pressure reducing device are connected in a ring), an electric compressor α [, a condenser 121
This constitutes a second refrigeration system I for a refrigerator compartment in which an evaporator αJ and an evaporator αJ are connected in an annular manner. Among these, the evaporator (8) of the first refrigeration system (9) is operated by the cold air circulation fan α9.
The evaporator α3 of the second refrigeration system I is arranged in the upper part of the refrigerator compartment (4) together with the cold air circulation fan (161). The machine room αη partitioned in the upper part houses the first refrigeration system (91 condensing units, i.e., an electric compressor (
5) and a condenser (6), and a condensing unit of the second refrigeration system I, that is, an electric compressor α [and a condenser Qυ, and one unit for forced air cooling of each condenser (6) and 1υ. The blower side is installed.

The condenser (6) for the freezer compartment has a plurality of plate-like fins (6A), a meandering refrigerant pipe (6B) perpendicular to the fins (6A), and a refrigerant pipe (6B). It is composed of a pair of left and right tube plates (6C) that support both ends, respectively.Similarly, the condenser aυ for the refrigerator compartment also has a plurality of plate-like fins (1
1A), a meandering refrigerant pipe (IIB) perpendicular to this fi/(IIA), and a pair of left and right tube plates (11C) that respectively support both ends of this refrigerant pipe (IIB).

At the same time, the upper ends of both tube plates (6C) of the condenser (6) for the freezer compartment are bent outward to form the upper end bent portion (6D), and the lower ends are bent outward to form the legs. The lower ends of both tube sheets (IIC) of the condenser Uυ for the refrigerator compartment are bent outward to form a lower end bent part (IID).

In the above configuration, both tube plates (
On top of the upper end bent portion (6D) formed in 6C), place the lower end bent portion (6D) formed on both tube plates (IIC) of the refrigerator compartment condenser aυ.
IID) and by connecting the two with screws, the freezer compartment condenser (6) and the refrigerator compartment condenser αυ can be constructed in two stages, upper and lower! ! are arranged in a predetermined position in machine room a, and both tube plates (6C) of the condenser (6) for the freezer compartment
The installation is completed by fixing the legs (6E) formed in ) to the bottom of the machine room (17) with screws or the like. Note that the refrigerator compartment condenser aυ may be installed after the freezing compartment condenser (6) is installed in the machine room aη.

In the embodiment of the present invention described above, the lower stage condenser is used for freezing and the upper stage condenser is used for refrigeration, but the lower stage condenser may be used for refrigeration and the upper stage condenser for freezing. , both may be used for freezing, or both may be used for refrigeration.

(G) Effects of the Invention As described above, the present invention makes it possible to extremely easily assemble a condenser with a two-stage stacked structure by using a pair of left and right tube plates that constitute each condenser of two independent refrigeration systems. This has the remarkable advantage that the installation space for the condensing unit can be significantly reduced.

In addition, with an air-cooled condensing unit like the one in the example, there is no need to install a separate blower for each condenser, and there is also a need to install a separate blower for each condenser, and there is also a need to install a separate blower for each condenser. There is no need to provide a filter for each condenser (the number of condenser-related parts can be significantly reduced).
