Description

  The present invention relates to a refrigerator structure having a high energy saving effect.

  FIG. 11 is a cross-sectional view of the basic structure of a freezer compartment of a conventional refrigerator.

  As shown in FIG. 11, a door gasket 12 is provided over the entire periphery at the end of the inner surface of the door 11, and a metal receiving member 14 configured on the front surface of the partition wall 13 that forms the receiving surface of the door gasket 12. And the door gasket 12 are brought into close contact with each other to prevent cold air from leaking to the outside.

  Cold air generated by a cooler 15 installed on the back of the main body is blown out from the discharge port 17 on the back of the freezer compartment 25 by a fan 16 to cool the food stored therein.

  Then, the cold air that has cooled the food reaches the upper front part of the storage cases 18 and 19, as shown by the arrows, and the space between the inner wall of the door 11 and the front surfaces of the storage cases 18 and 19, and the bottom surface of the storage case 19. Circulation returns from the return duct 21 to the cooler 15 through the space with the bottom wall of the storage chamber.

  In order to prevent the front of the partition wall 13 between the freezer compartment 25 and the upper storage chamber 22 from being cooled by the cool air reaching the front upper part of the storage case 18, and to prevent condensation on the front surface of the partition wall 13 due to the temperature difference between the inside and outside. A heat radiating pipe 23 is provided. The heat radiating pipe 23 uses a high-temperature refrigerant pipe in a refrigeration cycle (not shown), and heats the front surface of the partition wall 13 to a high temperature. The front upper air was heated and the cooling efficiency was reduced.

  In order to prevent this, a mechanism has been proposed in which a seal member 24 indicated by a two-dot chain line is provided in the upper space portion of the storage case 18 in the vicinity of the partition wall 13 so as to shield the cold air flow toward the door gasket 12. (For example, refer to Patent Document 1).

In the refrigerator, at least one of the upper and lower sides of the metal receiving member is provided with a heat exchange suppression space constituted by a partition wall and a seal member on the storage chamber side from the door gasket, and the seal member is connected to the door side. An independent space was formed And a Lumpur portion and the cool air guide part formed by connecting the storage compartment side together, suppressing the heat exchange into the storage compartment in the front Symbol exchange regulating space and the sealing portion and the cool air guide portion The seal portion and the cool air guide portion are separated when the door is opened, and a part of the seal portion and a part of the cool air guide portion are separated by deformation of the seal portion when the door is closed. It contacts and constitutes the 2nd heat exchange control space .

  About the refrigerator comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, the flow of cold air in the first freezer compartment 107 will be described. The cool air cooled by the cooler 112 is forcibly blown from the upper discharge port 120 to the case in the first freezer compartment 107 by the blower 113 that rotates as the motor rotates. The blown-out cool air is blown to the storage case of each storage room to cool the food stored. As indicated by the arrows, the cold air that has cooled the foods passes through the gap between the second freezer compartment 105 and the partition wall 118, and in the middle, the gap between the second freezer compartment case 105b and the upper freezer compartment case 107b. The airflow path configuration is such that the air flows through the gap of the lower freezer compartment case 107 c and is sucked from the suction port 125 and returns to the cooler 112.

  As described above, the cold air is heated by exchanging heat with the wall surface when circulating in the freezing temperature zone. In particular, in the upper stage cool air, heat exchange is performed most in the vicinity of the metal receiving member 123 heated by the heat radiating pipe 131, but the lower portion of the metal receiving member 123 is configured by the seal member 141 and the surface of the lower partition plate 118 b. By providing the heat exchange suppression space 140, heat transfer from the heat radiating pipe to the surface in contact with the cold air is reduced through the heat exchange suppression space 140 in which air does not circulate, thereby preventing an increase in the temperature of the surface in contact with the cold air. And heat exchange can be suppressed. Accordingly, it is possible to suppress the warming of the cold air, improve the cooling efficiency, and consequently reduce the power consumption.

  Further, since the cooling of the cold air can be suppressed, the cold air circulates at a low temperature, so that the temperature distribution in the entire freezing temperature zone can be kept uniform.

The door gasket 124 is configured to be in a position surrounded by the inner wall of the second freezer compartment door 105a and a space in which air does not circulate, and is a member that extends inside and outside the cabinet. It is possible to reduce the flow of cold air to the heat exchanger and suppress heat exchange.

  Due to the above effects, the metal receiving member 123 is cooled by heat exchange with the metal receiving member 123, and the metal receiving member 123 is prevented from being condensed due to a rapid temperature difference between the inside and outside of the metal receiving member 123. You can also.

  Further, the partition wall 118 is configured by assembling an upper partition plate 118a, a lower partition plate 118b, and a heat insulating member 118c between the upper and lower partition walls. The lower partition plate 118b includes a heat conduction suppressing portion 118d that is a cutout hole in a part of the configuration surface in the heat exchange suppression space 140 covered with the seal member 141, so that the heat transfer of the lower partition plate 118b is achieved. Accordingly, the heat of the metal receiving member 123 is prevented from entering the storage chamber, and the deterioration of the quality due to the appearance of the heat conduction suppressing portion 118d which is a notched hole can be prevented from the appearance. In addition, although the heat conduction suppression part 118d was made into the notch hole, it is good also as a thin part with a member board thickness.

As described above, in the present embodiment, the partition wall 118 is used to divide the inside of the heat insulating box 101 into a plurality of storage rooms to which cold air is supplied, and each door has a door that can be opened and closed. In the refrigerator provided with a door gasket that is in close contact with the metal receiving member formed on the door side front surface of the partition wall 118, and a seal member that suppresses heat exchange of cold air in the storage chamber directly against the door gasket 124. A structure for heating the metal receiving member 123 and the door gasket 124 is provided, and a heat exchange suppressing structure for suppressing heat exchange between the cool air in the storage chamber and the metal receiving member 123 is provided. By having a structure in which the heat exchange suppression space 140 configured by the seal member 141 and the surface of the lower partition plate 118b is provided between the chamber and the chamber, it has a surface that contacts cold air from the heat radiating pipe. Lumpur heat transfer to the member 141 is reduced, it is possible to suppress an increase in the temperature of the surface in contact with the cold air, it is possible to suppress the heat exchanger. Accordingly, it is possible to suppress the warming of the cold air, improve the cooling efficiency, and consequently reduce the power consumption.
