Description

Embodiments of the present invention relate to a refrigerator.

Conventionally, a refrigeration cycle built into the refrigerator body of a refrigerator is configured such that refrigerant compressed by a compressor flows sequentially through a condenser, a capillary tube, a cooler, and a suction pipe, and returns to the compressor again (for example, , see Patent Document 1 below).

In such a refrigeration cycle, if the refrigerant discharged from the compressor stagnates in the refrigerant piping located in the cooler room that houses the cooler, the amount of refrigerant that circulates may become insufficient or frost may form where the refrigerant stagnates. This may obstruct the flow of cold air, leading to a decrease in cooling efficiency.

(3) Configuration of refrigeration cycle 70 Next, the configuration of the refrigeration cycle 70 of the refrigerator 1 of this embodiment will be described based on FIGS. 5 and 6.

In the refrigeration cycle 70, the inlet side of a condenser 72, a dryer 73, and a switching valve 74 are connected in order from a refrigerant outlet of a compressor 71 that discharges high-temperature, high-pressure gaseous refrigerant by refrigerant piping.

One outlet of the switching valve 74 is connected to a refrigerated capillary tube 75 as a pressure reducing means via a refrigerant pipe that enters the heat insulating space 2c of the refrigerator body 2 from the machine room 36. The refrigerated capillary tube 75 extends from the heat insulating space 2c to the refrigerated cooler chamber 33, and in the refrigerated cooler chamber 33, the refrigerated cooler 30, the refrigerated accumulator 76, and the refrigerated suction pipe 77 are sequentially connected by refrigerant piping. The refrigerating suction pipe 77 enters the heat insulating space 2c from the refrigerating cooler room 33 and returns to the machine room 36 through the heat insulating space 2c.

The other outlet of the switching valve 74 is connected to a freezing capillary tube 78 as a pressure reducing means via a refrigerant pipe that enters the heat insulating space 2c of the refrigerator body 2 from the machine room 36. The frozen capillary tube 78 extends from the heat insulating space 2c through the introduction hole 83 (see FIG. 6) to the frozen cooler chamber 42, and in the frozen cooler chamber 42, the frozen cooler 38, frozen accumulator 79, and frozen suction pipe 80 are connected to the refrigerant.

Then, the outlet side of the check valve 81 and the outlet side of the refrigerating suction pipe 77 merge into one, and then are connected to the refrigerant inlet of the compressor 71 via a refrigerant pipe.

In such a refrigeration cycle 70, a refrigerant sealed in the cycle is compressed by a compressor 71 and changed into a high-temperature, high-pressure gaseous refrigerant, and then flows through a condenser 72 to radiate heat. The refrigerant that has flowed through the condenser 72 passes through a dryer 73 provided in the machine room 36 and then is guided to a switching valve 74.Based on a command from the refrigerator control unit 45, the switching valve 74 connects the refrigerated capillary tube 75 and the frozen capillary. It is switched and supplied to one side of the tube 78 and the pressure is reduced to facilitate vaporization.

The refrigerant, which is reduced in pressure and becomes liquid by passing through the refrigerated capillary tube 75 and the frozen capillary tube 78, is vaporized in the refrigerated cooler 30 and the frozen cooler 38, and removes heat from the surroundings, thereby reducing the pressure in the refrigerating cooler 30 and frozen cooling. The temperature of the container 38 is lowered and cold air is generated to cool the refrigerated space and the storage space.

The gas refrigerant that has passed through the refrigeration cooler 30 passes through the refrigeration suction pipe 77 and is sucked into the compressor 71 again, and the gas refrigerant that has passed through the refrigeration cooler 38 passes through the refrigeration suction pipe 80 and the check valve 81 to be refrigerated.

It is more preferable that the slope is gradually lowered toward the downstream side in the flow direction of the refrigerant.

Further, the upper fixing part 84 holds the sloped part 82a below the suction port 39a of the refrigerating blower 39, and prevents the sloped part 82a from overlapping the suction port 39a when viewed from the suction direction (backward) of the refrigerating blower 39. It is preferable to arrange the inclined portion 82a below the opening 39a.

The downstream side of the refrigerant pipe 38 a constituting the refrigeration cooler 38 in the refrigerant flow direction is connected to a refrigerant inlet provided below the refrigeration accumulator 79 . The refrigeration accumulator 79 is arranged on one side of the refrigeration cooler 38 on which the inlet hole 83 is provided in the width direction of the refrigerator, with the refrigerant inlet facing downward and the refrigerant outlet facing upward.

(5) Effect In the refrigerator 1 of this embodiment, since the upstream refrigerant pipe 82 connecting between the frozen capillary tube 78 and the frozen cooler 38 is provided with the inclined portion 82a, the amount of water flowing out from the frozen capillary tube 78 The refrigerant smoothly flows into the refrigeration cooler 38 without stagnation in the inclined portion 82a. Therefore, it is possible to prevent a shortage in the amount of refrigerant circulating through the refrigeration cycle 70, to prevent frost formation on the upstream refrigerant pipe 82, and to suppress a decrease in cooling efficiency.

In the refrigerator 1, the inclined part 82a is fixed to the refrigerator main body 2 by the upper fixing part 84 and the lower fixing part 38d. The inclined posture of the portion 82a can be maintained.
