  As shown in FIG. 1 and FIG. 2, the refrigerator 100 according to the present embodiment has a heat insulating material 103 such as hard foam urethane between an outer box 101 made of metal and an inner box 102 made of resin. The storage room is partitioned by an upper heat insulating partition 104 and a lower heat insulating partition 105, and a refrigerator compartment 110, a freezer compartment 120, and a vegetable compartment 130 are partitioned in order from the top.

  The evaporator 121 is disposed behind the freezer compartment 120, and the evaporator cover 140 is disposed in front of the evaporator 121 so as to partition the evaporator 121 and the freezer compartment 120.

  Here, the evaporator cover 140 has a blower 141 attached so as to be positioned above the evaporator 121, a cold air outlet 142 for blowing cold air to the freezer compartment 120, and a cold air distribution chamber for introducing cold air to the refrigerator compartment 110. 143 and the cold air led to the refrigerating chamber 110 circulates in the room, and the refrigerating chamber return air passage 144 returning from the refrigerating chamber return port 112 and a part of the cold air exchanged by the evaporator 121 are led to the vegetable compartment A vegetable room air passage 200 is formed.

  In the upper part of the cold air distribution chamber 143, a refrigerator air volume adjusting means 111 is arranged and embedded in the upper heat insulating partition 104. In this embodiment, it is an electric damper and is connected downstream of the cold air distribution chamber 143.

  The refrigerator compartment return port 112 is a suction port provided in the refrigerator compartment 110, and is configured in the upper heat insulating partition 104.

The refrigeration chamber return air passage 144 is covered with a heat insulating material, and has an upper end connected to the refrigeration chamber return port 112 and a lower end connected to the lower side of the evaporator 121.

  A vegetable room air passage 200 is disposed on the downstream side, which is the upper part of the refrigerator air volume adjusting means 111.

  The vegetable room air passage 200 communicates with the vegetable room discharge diversion air passage 104a configured in the left-right direction with respect to the refrigerator 100 and the vegetable room discharge air diversion air passage 104a in the vertical direction with the refrigerator air volume adjustment means 111 as the upwind. The vegetable room discharge air duct 145 and the vegetable room discharge duct extending vertically from the ceiling of the vegetable room 130 to approximately half the height of the vegetable room 130 through the lower heat insulating partition 105. 150.

  The vegetable compartment discharge diversion air passage 104 a is an air passage embedded in the upper heat insulating partition 104.

  The vegetable room discharge air passage 145 is formed in the evaporator cover 140, the upper end is connected to the vegetable room discharge diversion air passage 104 a, and the lower end is formed in the lower heat insulating partition 105 after crossing the rear of the freezer room up and down. Connected to the opening 105a. Here, the vegetable room discharge air passage 145 is covered with a heat insulator.

  3, 4, and 5, the vegetable room discharge duct 150 is provided in the vegetable room 130, the upper end is connected to the opening 105 a, and the upper and lower air passages 151 are closed around the lower surface portion serving as the lower end. It is the structure which the heat insulation body 152 covered. In this embodiment, the heat insulator 152 uses insulation, and a blowout port 153 is formed in each of the left and right side surfaces of the heat insulator 152 constituting the vegetable compartment discharge duct 150.

  Here, as the shape of the air outlet 153, in the present embodiment, at least the upper side 153b of the air outlet 153 has a downward slope toward the vertical air passage 151 as shown in FIG.

  The vegetable room discharge duct 145 of the present embodiment has a small capacity of the vegetable room 130, a uniform distribution of cold air into the vegetable room 130 is relatively easy, has a simple structure, is low in cost, and is small in size. Suitable for refrigerator.

  The vegetable room return air passage 105b is an opening formed in the lower heat insulating partition.

  The temperature control heater 131 is a heater with aluminum foil that is located behind the vegetable compartment and is disposed between the inner box 102 and the heat insulator 103.

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

  First, the refrigerant circulates in the cooling system by the operation of a compressor (not shown), and the cool air which is guided to the evaporator 121 by the forced circulation of the blower 141 and heat-exchanged is sent to each storage room by the blower 141. Cold air blows out from the outlet 142 into the freezer compartment 120 to cool the room. On the other hand, a part of the cold air divided in the cold air distribution chamber 143 passes through the cold room air volume adjusting means 111, cools the cold room 110, and then evaporates again via the cold room return port 112 and the cold room return air path 144. Return to the vessel 121.

Further, part of the cold air that has passed through the refrigerator compartment air volume adjusting means 111 passes through the vegetable compartment discharge branch air passage 104a constituting the vegetable compartment air passage 200, and moves downward in the vegetable compartment discharge air passage 145 formed in the vertical direction. It flows and is further guided to the vegetable room discharge duct 150 arranged in the vertical direction. Since the lower surface portion of the vegetable room discharge duct 150 is closed to form the abutting portion 201, the cold air once accumulates in the abutting portion 201, the flow of the cold air stops, and the flow direction is changed upward where the blowout port 153 is located. It will be. And since cold air blows off into the vegetable compartment 130 from the blower outlet 153 opened to the side wall of the vegetable compartment discharge duct 150 located above the abutting part 201, it is not discharged directly from the vegetable compartment discharge duct 150 into the vegetable compartment. Since cold air is once accumulated in the abutting portion 201 and discharged from the outlet 153, excessive cooling in the vegetable compartment can be reduced.

  The cold air in the vegetable compartment 130 then returns to the evaporator 121 from the vegetable compartment return air passage 105a.

  That is, since the temperature adjustment of the vegetable compartment 130 depends on the opening rate of the refrigerator air volume adjusting means 111, the vegetable compartment is utilized by using the heat generated by the temperature adjustment heater 131 in order to prevent the vegetable compartment 130 from being overcooled. The temperature of 130 is controlled appropriately.

  In general, the amount of heat generated by the temperature adjustment heater 131 is controlled by its energization rate (details are not described), and the energization rate is set high particularly in winter when the outside air temperature is low.

  Here, as shown in FIG. 6, when the refrigeration room air volume adjusting means 111 is closed or the cooling system is stopped, and the vegetable compartment 130 and the vegetable discharge air passage 145 are in the no-air state, In this case, it is not possible to prevent the warm humidity in the vegetable compartment 130 from rising in the cold air supply duct 45. On the other hand, frost formation can be prevented by setting the inside of the cold air supply duct 45 to a predetermined temperature by the heat generated by the heating device 47.

  On the other hand, in the refrigerator according to the present embodiment, even when the refrigerator compartment air volume adjusting means 111 is closed or the cooling system is stopped, and the vegetable compartment 130 and the vegetable compartment discharge air passage 145 are in the no-air state, The temperature in the vegetable room discharge air passage 145 does not rise.

  This is due to the effect of the vegetable compartment discharge duct 150. That is, the temperature of the vegetable room 130 in the non-wind state is about 5 ° C., whereas the temperature in the vegetable room discharge air passage 145 is reduced to about −15 ° C.

  Further, in the winter season when the outside air is low, the amount of heat generated by the temperature adjustment heater 131 is increased. As a result, the temperature difference (specific gravity difference) between the vegetable room discharge air passage 145 and the vegetable room 130 is increased, and natural convection is actively performed. And the time will be longer.

  Originally, due to this natural convection, the vegetable room discharge duct 150 flows into the vegetable room 130 with warm air, and frost formation should grow on the wall of the vegetable room discharge duct 150. While the lower end of the duct 45 is open and has a shape that actively takes in natural convection, the vegetable room discharge duct 150 of the present embodiment has a lower surface portion closed and is above the abutting portion 201. The outlet 153 is formed only in the direction of the side surface, and the opening edge of the outlet 153 has a downward slope from the inside of the vegetable compartment 130 (outside of the vegetable compartment outlet duct 150) toward the inside of the vegetable compartment outlet duct 150. Even if the vegetable compartment 130 and the vegetable compartment discharge air passage 145 are in the no-air state as shown in FIG. 7, the inside of the up-and-down air passage 151 and the vegetable compartment discharge duct 15 are provided. The rise in the temperature of the inside is suppressed, and the arrangement of the outlet 153, the vegetable room discharge duct 150 arranged in the vertical direction, and the butting part 201 formed on the lower surface of the vegetable room discharge duct 150 is structurally arranged. The trap structure makes it difficult for the air in the vegetable compartment to flow backward.

That is, the inflow of warm moisture into the vegetable room discharge duct 150 can be suppressed and frost formation can be prevented.

  As described above, in the present embodiment, by providing the outlet 153 of the vegetable room discharge duct 150 only on the left and right side walls, a trap structure is formed, so that cold air in the vegetable room 130 is generated in the vegetable room 130. Ascending airflow due to natural convection suppresses reverse inflow into the up-and-down air passage 151, and frost formation on the vegetable room discharge duct 150 can be prevented.

  Further, in the present embodiment, the upper side 153a of the air outlet is made a downward slope toward the up-and-down air path 151, so that resistance to natural convection due to only ascending, and warm and humid air into the up-and-down air path 151 Inflow, and frost formation on the vegetable room discharge air passage 145 can be prevented.

FIG. 8 is a front view of the vegetable compartment of the refrigerator in the second embodiment of the present invention.

  FIG. 9 is a cross-sectional view of the vegetable room discharge duct of the refrigerator in the second embodiment of the present invention.

  Similar to the first embodiment, a vegetable room air passage 200 is configured.

  8 is a cross-sectional view taken along the line AA in FIG. In FIG. 9, the vegetable room discharge duct 250 is composed of a vertical up-and-down air path 251 having an upper end connected to the opening 105 a and a horizontal horizontal air path 252 connected to the lower end of the up-and-down air path 251. 253.

  The horizontal horizontal air passage 252 is provided with an air outlet 252 a on the side facing the vertical air passage 251 in the vertical direction, and air outlets 252 b and 252 c are formed toward the rear of the refrigerator main body 100.

  In addition, a projection 254 that extends downward into the horizontal air passage 252 is formed on a connection portion between the vertical air passage 251 and the horizontal air passage 252 and on an upper surface portion of the horizontal air passage 252.

  The vegetable storage case 231 is a vegetable storage case disposed in a vegetable room that is pulled out in conjunction with the front and back movement of a vegetable drawer door (not shown).

  The vegetable room discharge duct 250 of the present embodiment is suitable when the capacity of the vegetable room 130 is large and it is difficult to evenly distribute the cold air to the vegetable room 130, and constitutes a horizontal air passage 252 in the horizontal direction. By blowing cold air from the formed outlets 252a, 252b, and 252c, a uniform flow of cold air to the vegetable compartment 130 becomes possible, which is particularly suitable for a large refrigerator.

  The following operation | movement and effect | action are demonstrated about the refrigerator compartment comprised as mentioned above.

  First, the cold air generated during the cooling operation is uniformly distributed to the vegetable compartment 130 by the vegetable compartment discharge duct 250 via the vegetable compartment discharge air passage 145. Here, since the outlets 252b and 252c are formed rearward in the refrigerator main body 100, the cold air is once opened to a space formed between the vegetable room discharge duct 250 and the inner box 102, and this space is opened downward. After moving to, it is uniformly dispersed in the front of the vegetable compartment 130.

  Here, when the air outlet is formed in the front of the horizontal wind tunnel, it is possible to prevent the warm and humid air of the vegetable room 130 that has become a windless state from flowing into the vegetable room discharge air passage 145, but before the air outlet. The case 231 will be located, and the temperature of a part of the vegetable storage case 231 in the vicinity of the outlet may partially decrease, and the food that comes into contact therewith may freeze.

  On the other hand, the outlets 252b, 252c of the present embodiment are formed so as not to face the vegetable storage case 231, that is, toward the rear of the refrigerator 100, in other words, facing the back wall of the vegetable compartment 130, It is possible to prevent the food from freezing by avoiding direct application of cold air to the vegetable storage case 231.

  Next, when the refrigerator air volume adjusting means 111 is closed or when the cooling system is stopped, and the vegetable room 130 and the vegetable room discharge air passage 145 are in the no-air state, the temperature adjustment heater 131 generates heat. Natural convection flows from the outlets 252a, 252b, 252c.

  Here, since each of the outlets 252a, 252b, and 252c is formed in a substantially horizontal direction, natural convection rising to vertical information can be suppressed from flowing into the vegetable room discharge duct 250, but gradually The inflowing warm and humid air travels along the upper part of the horizontal horizontal air passage 252 and eventually reaches the vegetable compartment discharge air passage 145 via the vertical air passage 251 in the vertical direction, so that the temperature in the vegetable compartment discharge air passage 145 rises. To do.

  Therefore, by forming the protrusion 254, it becomes a baffle plate and acts as a trap so that warm and humid air staying in the upper part of the horizontal horizontal air passage 252 is retained, so that the vertical up and down air passage 251 and the vegetable room discharge air The movement of warm and humid air to the path 145 is hindered, and the temperature rise in the vegetable room discharge duct 145 is prevented.

  As described above, in the embodiment, the outlets 252b and 252c face the vegetable storage case 231 so as not to face the rear of the refrigerator 100, in other words, face the rear wall of the vegetable compartment 130. By being formed, the cold air does not directly hit the vegetable storage case 231, there is no local temperature drop, and the stored food can be prevented from freezing.

  Further, the outlets 252b and 252c are positioned below the lower end of the protrusion 254.

  Moreover, in the form of the present embodiment, by forming the protrusion 254 in the vegetable compartment discharge duct 250, even when the warm and humid air generated in the vegetable compartment 130 flows into the horizontal air passage 252 due to the rising airflow, it heads upward. Therefore, the protrusion 254 becomes a baffle plate and becomes a trap so that the warm and humid air does not run sideways toward the inside of the vegetable chamber discharge duct 250, and frost formation inside the vegetable chamber discharge air passage 145 can be prevented. It is not necessary to attach a compensation heater for preventing frost formation in the chamber discharge air passage 145, and energy saving can be achieved.

  As described above, the refrigerator according to the present invention can prevent the growth of frost in the vegetable compartment discharge air passage without using a separate heat source and maintaining the temperature in the vegetable compartment discharge air passage above a predetermined value. Because it can save energy, it can also be used in commercial refrigerators with similar air paths.
