And a sub refrigeration system 500. The main refrigeration system 400 includes a main compressor 420, a main condenser 440, a main expander 460, and a main evaporator 480, and the sub refrigeration system 500 includes a sub compressor 520 and a sub. It consists of a condenser 440, a sub expander 560 and a sub evaporator 580.

The refrigerator main body 100 keeps food in a low temperature state by lowering the internal temperature. In addition, the refrigerator main body 100 may be divided into a refrigerating chamber 140 and a freezing chamber 180 by the partition wall 120. That is, there is an integrated type in which the inside of the refrigerator body 100 is integrated, and a separate type separated into the refrigerating chamber 140 and the freezing chamber 180. 6 to 9 illustrate the separate refrigerator, but the removal of the partition wall 120 is the same as the integrated unit, and thus a detailed description of the integrated refrigerator is omitted. Therefore, the present invention may be applied regardless of whether the interior of the refrigerator body 100 is an integrated type or a separate type, and any type of detachable top mount, bottom freeze, and side by side type may be applied. That is, the present invention is characterized in that the sub-refrigeration system 500 is installed in the ice making chamber 400 provided in the refrigerator door 200, which will be described later, any type of refrigerator may be used in the refrigerator door 200. This is because the sub-refrigeration system 500 is provided so as to exchange heat with the cold inside the ice-making chamber 400. Although not shown in the drawing, various types of baskets, shelves, and drawers may form an internal space of the refrigerator main body 100 to efficiently store various foods in the refrigerator main body 100.

The refrigerator door 200 opens and closes the refrigerator main body 100. The refrigerator door 200 is divided into a refrigerator compartment door 240 and a freezer compartment door 280 that open and close the refrigerator compartment 140 and the freezer compartment 180, respectively. The number of refrigerator doors 200 may be one or more, but when divided into the refrigerator compartment 140 and the freezer compartment 180, the refrigerator door 200 should be separated into a refrigerator compartment door 240 and a freezer compartment door 280, respectively. One or more of the refrigerating compartment door 240 and the freezing compartment door 280 may be provided.

It is installed to The partition wall 120 is not necessary in the case of an integrated refrigerator, but the partition wall 120 is required in the case of the separate refrigerator. In addition, the case of installing the main evaporator 480 to be described later to circulate the cold air of the refrigerating chamber 140 and the freezing chamber 180, respectively, and the refrigerating chamber 140 and the freezing chamber 180 by installing one main evaporator 480 May circulate the cold air together. When one main evaporator 480 is installed, since the partition wall 120 is formed between the refrigerating chamber 140 and the freezing chamber 180, circulation of cold air is blocked. Therefore, the cold air circulation path 125 is necessary.

As illustrated in FIG. 6, the cold air circulation path 125 penetrates through the partition wall 120 so that the cold air of the refrigerating chamber 140 and the freezing chamber 180 meet and circulate with each other. In the case of the separate refrigerator having the refrigerating compartment 140 and the freezing compartment 180 separated from each other, a cold flow path is formed so that the cold air heat-exchanged by the main evaporator 480 to be described later moves to the refrigerating compartment 140 through the freezing compartment 180 first. do. For example, a plurality of fans for forcibly transporting the cold air may be installed or a cold air flow path may be formed to move the cold air. In any case, the cold air circulation path 125 should be formed through the partition wall 120 so that the cold air of the freezing compartment 180 and the refrigerating compartment 140 meet and circulate with each other. However, when the refrigerating chamber evaporator 640 and the freezing chamber evaporator 680 which will be described later are separately installed in the refrigerating chamber 140 and the freezing chamber 180, the cold air circulation path 125 is not required. That is, in order to effectively control the temperatures of the refrigerating chamber 140 and the freezing chamber 180, the refrigerator compartment evaporator 484 and the freezer compartment evaporator 488 which will be described later are provided.

6 to 9, the ice making room 300 is installed inside the refrigerator door 200 so as not to be influenced by cold air inside the refrigerator main body 100, and stores the provided water as ice. do. The ice making chamber 300 may include an ice making container 320, an ice maker 340, and a dispenser 360. The ice maker 320 prepares the water provided by ice, and the ice maker 340 is disposed under the ice maker 320 to store the ice separately. In addition, the dispenser 360 is formed to be exposed to the outside so that the ice can be easily taken out from the outside. The ice making container 320, the ice maker 340, and the dispenser 360 constituting the ice making room 300 may be implemented in a conventional technology, and thus a detailed description thereof will be omitted. In addition, the ice making chamber 300 installed inside the refrigerator door 200 may be installed in any one of the refrigerating chamber door 240 or the freezing chamber door 280. In this case, the refrigerator door in which the ice making chamber 300 is installed is provided. Sub refrigeration system 500 to be described later should be installed together with (200). Accordingly, the sub refrigeration system 500 heat exchanges with the cold inside the ice making chamber 300 separately from the main refrigeration system 400 to be described later.

The main refrigeration system 400 is installed in the refrigerator main body 100, and the main compressor 420, the main condenser 440, the main to compress, condensate, and decompress the refrigerant to exchange heat with the cold inside the refrigerator main body 100. Expander 460 and main evaporator 480 are provided. The main compressor 420 and the main condenser 440 are generally installed together in a chamber called a machine room disposed under the refrigerator main body 100. Description of each component of the main refrigeration system 400 is the same as that used in the conventional refrigeration cycle, so the detailed description thereof will be omitted. However, the main evaporator 480 may be installed in any one of the refrigerating chamber 140 or the freezing chamber 180 when the refrigerator main body 100 is divided into the refrigerating chamber 140 and the freezing chamber 180. That is, as shown in FIG. 6 and FIG. 8, when the cold air temperatures of the refrigerating chamber 140 and the freezing chamber 180 are controlled by one main evaporator 480, the cold air of the refrigerating chamber 140 and the freezing chamber 180 is controlled. The cold air circulation path 125 formed through the partition wall 120 to meet and circulate with each other should be provided. In addition, as illustrated in FIGS. 7 and 9, the main evaporator 480 may be separated into a refrigerator compartment evaporator 484 and a freezer compartment evaporator 488 installed in the refrigerator compartment 140 and the freezer compartment 180, respectively. That is, the refrigerating chamber evaporator 484 controls the temperature of the cold air circulating in the refrigerating chamber 140, and the freezing chamber evaporator 488 controls the temperature of the cold air circulating in the freezing chamber 180, respectively. Accordingly, the temperature inside the refrigerating chamber 140 and the freezing chamber 180 can be accurately controlled.

The sub refrigeration system 500 is installed in the refrigerator door 200, and the sub compressor 520, the sub condenser 540 and the sub which compress, condense and depressurize the refrigerant to exchange heat with the cold inside the ice making chamber 300. An expander 560 and sub evaporator 580 are provided. The sub compressor 520, the sub condenser 540, the sub expander 560, and the sub evaporator 580 constituting the sub refrigeration system 500 may perform an operation process of performing a cooling cycle with the main refrigeration system 400. Since the same, detailed description thereof will be omitted. However, the sub compressor 520 of the sub refrigeration system 500 may be a variable displacement compressor capable of varying the flow rate of the refrigerant according to a user's selection. Accordingly, not only an ice making amount may be determined according to a user's preference, but also power consumption may be reduced.

Meanwhile, as illustrated in FIGS. 10 and 11, when the sub condenser 540 of the sub refrigeration system 500 condenses the refrigerant, heat of condensation 545 is generated, and the user is uncomfortable when installed in the refrigerator door 200. Since there is room for reduction, it is necessary to heat the condensation heat 545 to a place other than the front of the refrigerator main body 100 where the user will be located. To this end, the sub condenser 540 is installed on the upper portion of the refrigerator door 200 to radiate the condensation heat 545 upward, or is installed below the refrigerator door 200 to provide the condensation heat 545. It can radiate heat downward. In addition, a blower fan 550 may be further provided to blow the condensation heat 545 radiated upward and downward from the sub condenser 540 to move toward the rear of the refrigerator main body 100. The blower fan 550 may blow the condensation heat 545 radiated from the sub condenser 540 only when the blower fan 550 is installed above or below the refrigerator door 200 in which the sub condenser 540 is installed.

The embodiments of the present invention described above and shown in the drawings should not be construed as limiting the technical idea of the present invention. The scope of protection of the present invention is limited only by the matters described in the claims, and those skilled in the art will be able to modify the technical idea of the present invention in various forms.
