Definitions

  • the present invention relates to a configuration of a refrigerator that can achieve significant energy savings.
  • FIG. 11 is a cross-sectional view of a basic configuration of a freezing compartment of a conventional refrigerator.
  • door gasket 12 is provided along the entire perimeter on edges of an inner surface of door 11.
  • Door gasket 12 is in tight contact with metal receiving member 14 that is provided on a front face of partition wall 13, and which serves as a receiving surface for door gasket 12, thereby preventing cool air in freezing compartment 25 from leaking to outside.
  • Cool air generated in cooler 15 that is installed in a rear portion of a body is blown by fan 16 out of discharge port 17 on the backside of freezing compartment 25 into freezing compartment 25, and thus chills food stored in freezing compartment 25.
  • the cool air that has chilled the food reaches upper front portions of storage cases 18 and 19, and flows through spaces between an inner wall of door 11 and front faces of storage cases 18 and 19.
  • the cool air further flows through a space under the bottom of storage case 19 into return duct 21, and then therefrom returns to cooler 15 for circulation.
  • heat radiation pipe 23 is disposed in order to prevent the front face of partition wall 13 between freezing compartment 25 and upper storage compartment 22 from being cooled by the cool air that has reached the upper front portion of storage case 18, and thus prevent dew condensation from occurring on the front face of partition wall 13 due to a temperature difference between the interior and the exterior.
  • This heat radiation pipe 23 utilizes a high-temperature refrigerant pipe in a freezing cycle (not shown), and the heat therefrom heats the front face of partition wall 13 to a high temperature. Heating the front face of partition wall 13 to a high temperature prevents dew condensation, but at the same time, causes air in the upper front portion of freezing compartment 25 to be heated, thereby causing cooling efficiency to be reduced.
  • sealing member 24 indicated by the dotted line is provided in a space above storage case 18 in the vicinity of partition wall 13 so that the flow of cool air toward door gasket 12 is closed (see, e.g., PTL 1).
  • sealing member 24 is provided on partition wall 13 so as to contact with storage case 18 and to close the flow of cool air toward metal receiving member 14 in order to prevent the cool air in freezing compartment 25 from being heated by heat exchange with heated metal receiving member 14.
  • deterioration of sealing performance due to, for example, time-related deterioration of sealing member 24 makes sealing member 24 unable to close the cool air any more, and thus the cool air in freezing compartment 25 is heated by heat exchange with metal receiving member 14 in a high temperature. This presents a problem in that cooling efficiency is reduced.
  • PTL 2 discloses a refrigerator using a partition body for partitioning the inside of a main box into storage compartments to which cool air is supplied, and an openable and closable door being provided at the front faces of the storage compartments.
  • the door is provided with a gasket which makes close contact with a metallic contact member formed at the front surface of the partition body which is located on the door side.
  • the refrigerator is provided with a configuration which heats the contact members, and also with a suppression section which suppresses the exchange of heat between the cool air in the storage compartments and the contact member.
  • a refrigerator comprises a heat-insulating box including an inner box, an outer box, and a heat-insulating material filled between the inner box and the outer box; a partition wall that vertically divides an interior of the heat-insulating box into a plurality of storage compartments, to which cool air is supplied; an openable door provided in front of each of the plurality of storage compartments; and a door gasket in tight contact with a metal receiving member that is provided on a front face of the partition wall facing the doors.
  • the refrigerator further includes a sealing member attached to the partition wall, and having a sealing portion for partially closing a gap between one of the doors and the partition wall, a heat exchange suppression space formed by the partition wall and the sealing member on at least one of top and bottom of the metal receiving member at one side of the door gasket facing an inside of one of the plurality of storage compartments, the sealing member including a cool air guide, and a connection portion connecting the cool air guide with the sealing member provided on a storage compartment side with respect to a center of the heat exchange suppression space, a part of the sealing portion of the sealing member in contact with a part of the cool air guide portion forming a second heat exchange suppression space.
  • the refrigerator according to the present invention uses a partition wall to divide an interior of a heat-insulating box into a plurality of storage compartments, to which cool air is supplied, and includes an openable door in front of each of the storage compartments.
  • a door gasket is provided which is in tight contact with a metal receiving member that is provided on the front face of the partition wall facing the doors.
  • a configuration such that the metal receiving member is heated is also provided.
  • a heat exchange suppression space is provided which suppresses heat exchange between cool air in the associated storage compartment and the metal receiving member.
  • the heat exchange suppression space is formed by the partition wall and a sealing member, between the metal receiving member and the associated storage compartment.
  • the present invention can suppress heat exchange with the outside, improve cooling efficiency, and thus provide a refrigerator having reduced power consumption.

  • FIG. 2 is a cross-sectional view taken along line 2-2 of FIG. 1 .
  • FIG. 3 is an enlarged cross-sectional view of a main portion of the refrigerator according to the first embodiment of the present disclosure.

  • This placement provides the following advantage: the space for machine compartment that has been located in the bottom portion of heat-insulating box 101, which is convenient for users, in a conventional refrigerator, can be advantageously turned into a storage compartment capacity.

  • Sealing portion 143 has a connection portion on the door side of the portion constituting heat exchange suppression space 140, of sealing member 147.
  • Cool air guide 144 has a connection portion on the storage compartment side of the portion constituting heat exchange suppression space 140, with respect to the center in the forward and backward directions of sealing member 147. Sealing portion 143 and cool air guide 144 respectively have different connection portions, and are formed monolithically with sealing member 147.
  • Sealing member 147 is secured by fitting sealing member fixing section 146 into protrusion 118e of lower partition plate 118b. Heat-insulating member 150 is disposed in heat exchange suppression space 140. Heat-insulating member 150 is adhesively secured using the inner surface of sealing member 147 as the adherend surface, which adheres to a foam member using, for example, polyethylene material.
  • sealing member 147 has gap prevention angle A, which is an acute angle greater than or equal to one degree, between the surface constituting heat exchange suppression space 140 and sealing member fixing section 146 or the surface of lower partition plate 118b. Also, sealing member 147 has droop prevention angle B, which is an acute angle greater than or equal to one degree, between the surface constituting heat exchange suppression space 140 and cool air guide 144.
  • Sealing member 147 which constitutes heat exchange suppression space 140 provided under metal receiving member 123, includes cylindrical sealing portion 143. Since this sealing portion 143 is disposed so as to contact with a part, on the storage compartment side, of second freezing compartment door 105a of second freezing compartment 105, door gasket 124 is formed in a position enclosed by both the inner wall of second freezing compartment door 105a and a space in which no air circulation occurs. This configuration can reduce the flow of cool air toward door gasket 124, which is a member facing both the interior and the exterior of the refrigerator, and thus can suppress heat exchange between air inside and air outside the refrigerator.
  • cool air guide 144 prevents cool air that has been blown out by ventilator 113 from directly flowing onto the surface constituting heat exchange suppression space 140, of sealing member 147, and thus suppresses heat exchange between the air inside heat exchange suppression space 140 and the cool air.
  • cool air guide 144 has a downward-curved edge so that the cool air is directed toward the associated storage compartment, and providing a shape that also makes it less likely for the cool air to flow onto sealing portion 143 also improves the heat exchange suppression effect of sealing portion 143.
  • heat-insulating member 150 placed inside heat exchange suppression space 140 further improves the heat insulation effect of heat exchange suppression space 140.
  • Sealing portion 143 and cool air guide 144 of sealing member 147 are placed spaced apart when second freezing compartment door 105a is open, but upon closure of second freezing compartment door 105a, sealing portion 143 is deformed as shown in FIG. 7 , and thus moves toward the storage compartment side. This deformation of sealing portion 143 causes a part of sealing portion 143 and a part of cool air guide 144 to come in contact with each other, thereby forming second heat exchange suppression space 161. Second heat exchange suppression space 161 further reduces the effect of discharged cool air upon heat exchange suppression space 140 since there is no movement of the air inside the space, and thus further improves the heat insulation effect of heat exchange suppression space 140.
  • Sealing member 147 has gap prevention angle A, which is an acute angle greater than or equal to one degree, between the surface constituting heat exchange suppression space 140 and sealing member fixing section 146 or the surface of lower partition plate 118b. Accordingly, after sealing member 147 has been attached on partition wall 118, sealing member 147 is deformed about spring section 160, and thus a force is produced so as to move sealing member 147 toward lower partition plate 118b. This can prevent a gap from being generated between sealing member 147 and partition wall 118. Prevention of a gap between sealing member 147 and partition wall 118 ensures appearance quality, and at the same time, ensures that the heat exchange suppression effect of heat exchange suppression space 140 is exerted.
  • gap prevention angle A is an acute angle greater than or equal to one degree
  • droop prevention angle B is provided which is an acute angle greater than or equal to one degree, between the surface constituting heat exchange suppression space 140 and cool air guide 144.
  • cool air guide 144 which is likely to droop due to its own weight, is configured so as to be raised in advance. Therefore, irregularity due to drooping is compensated, and thus contacting with food or the like is prevented in practical use. It is also ensured that the heat exchange suppression effect of second heat exchange suppression space 161 is exerted.
  • heat-insulating member 150 is adhesively secured using the inner surface of sealing member 147 as the adherend surface
  • the surface of partition wall 118 may be used as the adherend surface.
  • FIG. 8 is an enlarged cross-sectional view of a main portion of a refrigerator according to a fourth embodiment of the present disclosure.
  • heat radiation pipe 131 is disposed in metal receiving member 123 in order to prevent dew condensation from occurring on the outer surface of the associated storage compartment.
  • Metal receiving member 123 is heated by means of the heat from this heat radiation pipe 131.
  • Partition wall 118 is formed by vertically mating upper partition plate 118a with lower partition plate 118b.
  • partition wall 118 is configured such that heat-insulating member 118c is interposed between upper partition plate 118a and lower partition plate 118b, thereby providing heat insulation between storage compartments set within different temperature ranges.
  • Heat exchange suppression space 140 provided under metal receiving member 123 is formed by sealing member 148, a surface of lower partition plate 118b, and door gasket 124. Sealing portion 142 of sealing member 148 is disposed so as to contact with a part, on the storage compartment side, of second freezing compartment door 105a of second freezing compartment 105.
  • Heat exchange suppression space heat-insulating member 150 is disposed in heat exchange suppression space 140. Heat-insulating member 150 is adhesively secured using the inner surface of sealing member 148 as the adherend surface, which adheres to a foam member using, for example, polyethylene material.
  • Heat exchange suppression space 140 in which heat exchange suppression space heat-insulating member 150 is disposed, is formed by sealing member 148, a surface of lower partition plate 118b, and door gasket 124. Preventing contact between sealing member 148 and door gasket 124 can prevent heat transfer into the associated storage compartment by heat conduction from door gasket 124 to sealing member 148, and thus can further improve the heat insulation effect of heat exchange suppression space 140.
  • FIG. 9 is an enlarged cross-sectional view of a main portion of a refrigerator according to a fifth embodiment of the present disclosure.
  • FIG. 10 is a perspective view of the sealing member of the refrigerator according to the fifth embodiment of the present disclosure.
  • heat radiation pipe 131 is disposed in metal receiving member 123 in order to prevent dew condensation from occurring on the outer surface of the associated storage compartment.
  • Metal receiving member 123 is heated by means of the heat from this heat radiation pipe 131.
  • Partition wall 118 is formed by vertically mating upper partition plate 118a with lower partition plate 118b.
  • partition wall 118 is configured such that heat-insulating member 118c is interposed between upper partition plate 118a and lower partition plate 118b, thereby providing heat insulation between storage compartments set within different temperature ranges.
  • Heat exchange suppression space 140 provided under metal receiving member 123 is formed by sealing member 149 and a surface of lower partition plate 118b. Sealing portion 142 of sealing member 149 is disposed so as to contact with a part, on the storage compartment side, of second freezing compartment door 105a of second freezing compartment 105.
  • Heat-insulating member 150 is disposed in heat exchange suppression space 140. Heat-insulating member 150 is adhesively secured using the inner surface of sealing member 149 as the adherend surface, which adheres to a foam member using, for example, polyethylene material.
  • Edge cut-out opening 170 is provided in a portion constituting heat exchange suppression space 140, of sealing member 149, and the opening of edge cut-out opening 170 is covered by heat-insulating member 150.
  • Sealing member 149 which constitutes heat exchange suppression space 140 provided under metal receiving member 123, includes sealing portion 142, which is disposed so as to contact with a part, on the storage compartment side, of second freezing compartment door 105a of second freezing compartment 105.
  • door gasket 124 is formed in a position enclosed by both the inner wall of second freezing compartment door 105a and a space in which no air circulation occurs. This can reduce the flow of cool air toward door gasket 124, which is a member facing both the interior and the exterior of the refrigerator, and thus can suppress heat exchange between air inside and air outside the refrigerator.
  • Placement of heat exchange suppression space heat-insulating member 150 inside heat exchange suppression space 140 can improve the heat insulation effect of heat exchange suppression space 140.
  • edge cut-out opening 170 in a portion constituting heat exchange suppression space 140, of sealing member 149 prevents heat conduction to the associated storage compartment by heat conduction of sealing member 149. Also, covering the opening of edge cut-out opening 170 by heat exchange suppression space heat-insulating member 150 can prevent heat exchange with the interior of heat exchange suppression space 140 via edge cut-out opening 170, and thus can further improve the heat insulation effect of heat exchange suppression space 140.
  • the present invention provides a heat-insulating box including an inner box, an outer box, and heat-insulating material filled between the inner box and the outer box, and a partition wall that vertically separates storage compartments set within different temperature ranges within the heat-insulating box.
  • the partition wall divides the interior of the heat-insulating box into a plurality of storage compartments, to which cool air is supplied.
  • An openable door is provided in front of each of the storage compartments.
  • a door gasket is provided which is in tight contact with a metal receiving member that is provided on a front face of the partition wall facing the doors.
  • a sealing member is provided which has a sealing portion that is attached to the partition wall, and that partially closes a gap between a corresponding one of the doors and the partition wall.
  • a heat exchange suppression space formed by both the partition wall and the sealing member is provided on the inward side of the corresponding storage compartment with respect to the door gasket, at least either on the top of, or on the bottom of, the metal receiving member.

  • the cool air guide includes a connection portion with the sealing member, on the storage compartment side with respect to the center in the forward and backward directions of the heat exchange suppression space. Therefore, heat exchange between the periphery of the metal receiving member and the cool air guide cooled by the cool air by heat conduction of the sealing member can be reduced, and thus a refrigerator having reduced power consumption can be provided.
  • the sealing portion of the sealing member alone forms a sealing portion independent space, which is a second heat exchange suppression space. Therefore, heat exchange between the periphery of the metal receiving member and the associated storage compartment via the sealing portion can be suppressed by the space, and thus a refrigerator having reduced power consumption can be provided.
  • a heat exchange suppression space heat-insulating member is provided in the heat exchange suppression space of the sealing member.
