A first embodiment of the present invention will be described below with reference to FIGS. 1 to 5. FIG. 1 is the refrigerator of the present invention. This cool box 1 has a cool box main body 2 and a cover body 3 .

The cold storage main body 2 has a cold storage container 4 and a lid body 5 and is configured in a box shape. The cold insulation container 4 has a cold insulation section 6 and an engine section 7 . The cold insulation compartment 6 includes a container 8, an outer shell 9 provided outside the container 8, and a heat insulating portion 10 provided between the container 8 and the outer shell 9. be. At least the side surface portion 8W of the container 8 is made of a heat-conductive metal such as aluminum. Note that the entire container 8 may be made of aluminum or the like. On the other hand, the outer shell 9 is made of a synthetic resin or the like having a low thermal conductivity. A hydrophilic layer 11 is formed on the surface of the outer shell 9 . Further, the heat insulating part 10 can be made of polystyrene foam, urethane foam, or vacuum heat insulating panel alone or in combination.

The engine section 7 is provided with a cold-storage main body air inlet 12 , a cool-storage main body air outlet 13 , and a blower 14 . A refrigerator (not shown) is accommodated in the engine section 7 . The air blower 14 has an airflow that flows in from the cooler main body inlet 12 and flows out from the cooler main body outlet 13 in order to discharge heat generated by the operation of the refrigerator to the outside of the cooler main body 2 . It is for forming F. The cold-storage main body intake port 12 and the cold-storage main body exhaust port 13 are separated from each other at the engine section 7 so that the airflow flowing out from the cold-storage main body exhaust port 13 does not flow into the cold storage main body suction port 12. position. Specifically, the cold-storage main body air inlet 12 and the cool-storage main body air outlet 13 are provided on different surfaces of the engine section 7, respectively. In this example, the cold-storage main body intake port 12 is provided on the front outer wall 15 of the engine section 7 , and the cool-storage main body exhaust port 13 is provided on the left outer wall 16 of the engine section 7 .

The cover body 3 is made of a synthetic resin or the like having a low thermal conductivity. The cover body 3 has a bottom portion 17, a front side wall 18, a rear side wall 19, a right side wall 20, and a left side wall 21, and is formed into a vessel-like shape with an upward opening. An inward flange portion 22 is formed at the upper open end of each of the side walls 18, 19, 20 and 21. As shown in FIG. The inward flange portion 22 forms a slight gap G1 between the outer wall of the cold-storage main body 2 and the outer shell 9 when the cold-storage main body 2 is accommodated in the cover body 3 from above. is dimensioned to In addition, the inward flange portion 22, that is, the upper open end of the cover body 3, is formed in the cool body body 2 when the body 2 is accommodated in the cover body 3 from above. It is located above the intake port 12 . For this reason, the cold-storage main body intake port 12 is covered with the cover body 3 . At a portion of the inward flange portion 22 that faces the engine portion 7, a blocking portion 23 is provided that abuts against the outer wall of the engine portion 7 to block the inflow of airflow. In this embodiment, the blocking portion 23 is formed separately from a material such as rubber or sponge that can adhere to the outer wall. good too. In addition, an intake port 24 is formed in the right side wall 20 . The intake port 24 is formed with a guide portion 25 that guides the airflow F downward. Also, an exhaust port 26 is formed in the left side wall 21 . The air outlet 26 is provided so as to communicate with the cold storage body air outlet 13 . Furthermore, an introduction portion 27 is provided on the inner surface side of the front side wall 18 for guiding the airflow F from below the cover body 3 to the cooling box main body intake port 12 . The introduction part 27 is formed in the shape of a rib extending vertically on the inner surface of the front side wall 18 closer to the intake port 24 than the intake port 12 of the cold storage main body.

A plurality of spacers 28 are provided between the bottom portion of the refrigerator main body 2 and the bottom portion 17 of the cover body 3 to form a gap G2 therebetween. These spacers 28 may be provided as legs of the cold-packed main body 2, but may be formed integrally with the bottom portion 17 of the cover body 3, or may be formed independently of the cold-packed main body 2 and the cover body 3. may be provided. Moreover, it is desirable that these spacers 28 are made of a structure or material that absorbs vibrations generated by the refrigerator (not shown).

Next, the operation of this embodiment will be described. First, the user operates the operation part (not shown) of the cold storage main body 2 to operate the refrigerator and the blower 14 . As a result, the space surrounded by the container 8 and the lid 5 is cooled. By cooling this space, the articles housed in this space are also cooled. Further, the heat generated by the refrigerator is discharged to the outside of the cold-storage main body 2 by the airflow F generated by the blower 14 . This airflow F flows into the engine section 7 through the cold-storage main body intake port 12 and flows out of the engine section 7 through the cold-storage main body exhaust port 13 .

The cold insulation container main body 2 can be used alone. However, when the cooling performance of the refrigerator is high and the inside of the space can be cooled to an extremely low temperature, even if the leakage of cold heat is suppressed by the heat insulating portion 10 with high heat insulation, the leakage of cold heat cannot be completely suppressed. First, there is a risk that the outer shell 9 of the cold insulation compartment 6 of the cold insulation container body 2 may be dewed, so it is desirable to use the cold insulation container body 2 while it is housed in the cover body 3 . Thus, the condensed water generated on the outer shell 9 flows down the surface of the outer shell 9 and is accumulated in the bottom portion 17 of the cover body 3 .

It should be noted that dew condensation may also occur above the inward flange portion 22 of the outer shell 9 of the cold insulation compartment 6 . It is necessary that the condensed water generated here flows down the surface of the outer shell body 9 and accumulates in the bottom portion 17 of the cover body 3 . Therefore, it is necessary to provide the gap G1 between the outer shell 9 and the inward flange portion 22 to allow the condensation water to pass. That is, the condensed water generated on the outer shell 9 is accumulated in the bottom portion 17 of the cover body 3 regardless of whether it is generated above or below the inward flange portion 22 . If the gap G1 is too narrow, the flowing condensed water will be held between the outer shell 9 and the inward flange portion 22 by surface tension. For this reason, the gap G1 needs to have a dimension sufficient to allow the condensed water to flow.

On the other hand, dew condensation hardly occurs on the outer wall of the engine section 7 . This is because the surface temperature of the outer wall of the engine section 7 is less likely to fall below the dew point due to the heat generated by the refrigerator housed in the engine section 7 . Therefore, between the outer wall of the engine portion 7 and the inward flange portion 22, the gap G1 for passing the condensed water is not necessary.

Then, when the air blower 14 operates, an air flow F flows from the air intake port 24 into the gap between the cold storage main body 2 and the cover body 3, and this air flow F flows from the cold storage main body air intake port 12 to the engine section 7. inside and is discharged to the outside of the engine section 7 through the cold-storage main body exhaust port 13 . As described above, since the cold-storage main body exhaust port 13 communicates with the exhaust port 26, when the airflow F flows out of the cold-storage main body exhaust port 13 to the outside of the engine section 7, 26 to the outside of the cover body 3 . By operating the air blower 14 of the cold-storage main body 2 in this way, the airflow F flows between the cold-storage main body 2 and the cover body 3 . As described above, since the guide portion 25 that guides the airflow F downward is formed in the intake port 24, the airflow F flowing in from the intake port 24 is directed downward, and the bottom of the cold storage main body 2 and the bottom portion 17 of the cover body 3 . Further, since the introduction portion 27 is provided on the inner surface side of the front side wall 18 of the cover body 3, the airflow F rises from the gap G2 and flows into the engine portion 7 from the cold storage main body intake port 12. . Therefore, the airflow F reliably flows through the gap G2 between the intake port 24 and the cold-storage main body intake port 12 .

When the airflow F flows through the gap G2 while the condensed water is accumulated in the bottom portion 17 of the cover body 3, the airflow F evaporates the condensed water. In addition, if the gap G1 is wide, outside air will flow into the space between the cold-packed main body 2 and the cover body 3 through the gap G1. In this case, the flow velocity of the airflow F flowing through the gap G2 is slowed down, making it difficult for the condensed water to evaporate. However, as described above, by providing the hydrophilic layer 11 on the surface of the outer shell 9, the condensed water generated on the surface of the outer shell 9 is less likely to become droplets. Therefore, the condensed water generated above the inward flange portion 22 of the outer shell 9 can pass through the gap G1 even if the gap G1 is narrowed to some extent. Therefore, by narrowing the gap G1 and suppressing the inflow of outside air through the gap G1, it is possible to suppress the decrease in the flow velocity of the airflow F, and the condensed water generated on the surface of the outer shell body 9 can be prevented from flowing into the gap. You can pass G1. As a result, the condensed water flows down along the surface of the outer shell 9 and accumulates on the bottom 17 of the cover 3 . Since the airflow F flowing from the intake port 24 passes through the gap G2, the condensed water on the lower surface of the outer shell 9 and the condensed water accumulated on the bottom 17 of the cover 3 are The airflow F will evaporate efficiently.

The water vapor generated by the evaporation of the condensed water flows into the engine section 7 from the cold storage main body air inlet 12 together with the airflow F, passes through the cold storage main body air outlet 13 and the air outlet 26, and passes through the cover body 3. discharged outside.

As described above, the present invention is a cold storage body 1 having a box-shaped cold storage body 2 and a cover body 3 with an upper opening covering the outer lower part of the cold storage body 2, It has a plurality of spacers 28 for forming the gap G2 between the bottom portion and the bottom portion 17 of the cover body 3, the cover body 3 has an intake port 24 and an exhaust port 26, and the cold storage box. Since the main body 2 has the blower 14, the condensed water generated on the surface of the cold-storage main body 2 is caused to evaporate by applying the air flow F flowing from the air inlet 24 and flowing out from the air outlet 26. - 特許庁Therefore, the condensed water can be hygienically treated with a simple structure at a low cost.

Further, according to the present invention, the cooler main body 2 has a cooler main body intake port 12, a cooler main body outlet 13, and the air blower 14 for exhausting heat, and at the upper opening end of the cover body 3, A certain inward flange portion 22 is positioned above the cold-storage main body intake port 12 in a state in which the cold-storage main body 2 is accommodated, and the air outlet 26 is provided so as to communicate with the cold-storage main body air outlet 13. As a result, the structure of the cover body 3 itself can be made simple, and an increase in cost can be minimized.

Further, according to the present invention, the cold storage main body 2 has the cold storage compartment 6 and the engine section 7, and the cool storage main body air inlet 12, the cool storage main body exhaust port 13, and the blower 14 are connected to the engine section. 7, and a blocking portion 23 is provided on the upper portion of the cover body 3 to block the inflow of airflow from between the outer wall of the engine section 7 and the cold insulation compartment 6 and the cover body 3, which are prone to condensed water. It is possible to evaporate the condensed water by allowing the airflow F to flow between.

Further, according to the present invention, by providing the cover body 3 with the introduction part 27 for guiding the air flow F from below to the cold storage main body intake port 12, the bottom part of the cold insulation compartment part 6 and the bottom part 17 of the cover body 3 It is possible to evaporate the condensed water that has flowed down by allowing the airflow F to flow between.

Furthermore, according to the present invention, by forming the guide portion 25 for guiding the outside air downward in the intake port 24 of the cover body 3, the airflow between the bottom portion of the cold storage main body 2 and the bottom portion 17 of the cover body 3 is improved. By allowing F to flow, it is possible to evaporate the condensed water that has flowed down.

Next, a second embodiment of the invention will be described with reference to FIGS. 6 to 8. FIG. 31 is the cold storage box of the present invention. This cool box 31 has a cool box main body 32 and a cover body 33 .

The cold storage main body 32 has a cold storage container 34 and a lid body 35 and is configured in a box shape. The cold insulation container 34 is composed of a container 38, an outer shell 39 provided outside the container 38, and a heat insulating portion 40 provided between the container 38 and the outer shell 39. . At least the side surface portion 38W of the container 38 is made of a heat-conductive metal such as aluminum. Note that the entire container 38 may be made of aluminum or the like. On the other hand, the outer shell 39 is made of synthetic resin or the like having low thermal conductivity. A hydrophilic layer 41 is formed on the surface of the outer shell 39 . Further, the heat insulating portion 40 can be made of polystyrene foam, urethane foam, or vacuum heat insulating panel alone or in combination.

The cover body 33 is made of a synthetic resin or the like having a low thermal conductivity. The cover body 33 has a bottom portion 47, a front side wall 48, a rear side wall 49, a right side wall 50, and a left side wall 51, and is formed into a container shape with an upward opening. An inward flange portion 52 is formed at the upper open end of each of the side walls 48, 49, 50, 51. As shown in FIG. The inward flange portion 52 is sized to form a slight gap G3 between the cold-storage main body 32 and the outer shell 39 of the cold-storage main body 32 when the cold-storage main body 32 is accommodated in the cover body 33 from above. be decided. In addition, an intake port 54 is formed in the right side wall 50 . The intake port 54 is formed with a guide portion 55 that guides the airflow F downward. Also, an exhaust port 56 is formed in the left side wall 51 . The exhaust port 56 is provided with an air blower 57 and a duct portion 58 for guiding the airflow F to the air blower 57 from below.

A plurality of spacers 59 are provided between the bottom portion of the refrigerator main body 32 and the bottom portion 47 of the cover body 33 to form a gap G4 therebetween. These spacers 59 may be provided as legs of the cold-storage main body 32, may be formed integrally with the bottom portion 47 of the cover body 33, or may be formed independently of the cold-storage main body 32 and the cover body 33. may be provided.

Next, the operation of this embodiment will be described. First, the user opens the lid 35 of the cold storage main body 32 and puts a cold insulator (not shown) into the container 38 . As a result, the space surrounded by the container 38 and the lid 35 is cooled. By cooling this space, the articles housed in this space are also cooled.

The cold insulation container main body 32 can be used alone. However, when the cold storage agent has a large amount of cold storage and the inside of the space can be cooled to an extremely low temperature, even if the leakage of cold heat is suppressed by the heat insulating portion 40 with high heat insulation, the leakage of cold heat cannot be completely suppressed. First, there is a risk that the outer shell 39 of the cold insulating container body 32 will be dewed, so it is desirable to use the cold insulating container main body 32 while being housed in the cover body 33 . Thus, the condensed water generated on the outer shell 39 flows down the surface of the outer shell 39 and is accumulated in the bottom portion 47 of the cover body 33 .

It should be noted that there is a possibility that dew condensation may occur even above the inward flange portion 52 of the outer shell 39 . It is necessary that the condensed water generated here flows down the surface of the outer shell body 39 and accumulates in the bottom portion 47 of the cover body 33 . Therefore, between the outer shell 39 and the inward flange portion 52, it is necessary to provide the gap G3 for passing the condensed water. That is, the condensed water generated on the outer shell 39 is stored in the bottom portion 47 of the cover body 33 regardless of whether it is generated above or below the inward flange portion 52 . If the gap G3 is too narrow, the flowing condensed water will be held between the outer shell 39 and the inward flange portion 52 by surface tension. For this reason, the gap G3 needs to have a dimension sufficient to allow the condensed water to flow.

Then, when the blower 57 operates, an airflow F flows from the intake port 54 into between the cold-storage main body 32 and the cover body 33, and this airflow F passes through the blower 57 from the duct portion 58. It is discharged to the outside of the cover body 33 through the exhaust port 56 . As described above, since the guide portion 55 for guiding the airflow F downward is formed in the intake port 54, the airflow F flowing in from the intake port 54 changes its direction downward, and the bottom of the cold storage main body 32 and the bottom portion 47 of the cover body 33 . Further, since the duct portion 58 is provided on the inner surface side of the right side wall 21 of the cover body 33, the airflow F rises from the gap G4, passes through the air blower 57, and flows through the cover body 33 from the exhaust port 56. discharged outside. Therefore, the airflow F reliably flows through the gap G4 between the intake port 54 and the exhaust port 56. As shown in FIG.

When the air flow F flows through the gap G4 while the condensed water is stored in the bottom portion 47 of the cover body 33, the air flow F evaporates the condensed water. In addition, if the gap G3 is wide, outside air flows into the space between the cold-packed main body 32 and the cover body 33 through the gap G3. In this case, the flow velocity of the airflow F flowing through the gap G4 is slowed down, making it difficult for the condensed water to evaporate. However, as described above, by providing the hydrophilic layer 41 on the surface of the outer shell 39, the condensed water generated on the surface of the outer shell 39 is less likely to become water droplets. Therefore, the condensed water generated above the inward flange portion 52 of the outer shell 39 can pass through the gap G3 even if the gap G3 is narrowed to some extent. Therefore, by narrowing the gap G3 and suppressing the inflow of outside air through the gap G3, it is possible to suppress the decrease in the flow velocity of the airflow F, and the dew condensation water generated on the surface of the outer shell body 39 can be prevented from flowing into the gap. You can pass G3. As a result, the condensed water flows down along the surface of the outer shell body 39 and accumulates on the bottom portion 47 of the cover body 33 . Since the airflow F flowing from the intake port 54 passes through the gap G4, the condensed water on the lower surface of the outer shell 39 and the condensed water accumulated on the bottom 47 of the cover 33 are The airflow F will evaporate efficiently.

The water vapor generated by evaporation of the condensed water is discharged to the outside of the cover body 33 together with the airflow F through the exhaust port 56 .
