  2. Description of the Related Art In recent years, home delivery services for foods and beverages that regularly deliver foods and beverages ordered through mail order sales to homes are becoming widespread. In addition, as the number of single-living households increases, the demand for home delivery services for foods and beverages is also increasing.

  In regular home delivery services, food, beverages, etc. can be stored and stored in a heat-insulated cool box when the orderer is absent.

  However, since the cold storage box uses cold storage means such as ice, dry ice, and cold storage material, it can be kept at an appropriate temperature only for several hours.

  In addition, in a home delivery service using a home delivery service, it is often impossible to receive food, beverages, etc. when the orderer is absent.

  Conventionally, a cold storage provided with a cooling means has been proposed for such problems (see, for example, Patent Document 1).

  The cool box described in Patent Document 1 includes a lid body that opens and closes, and a lock device that can be locked in a state in which the lid body is closed, and each of the storage spaces includes a cooling chamber, clothing, and other parcels. The room is partitioned into a room temperature room for storing articles.

Become.

  Thereby, by suppressing the inflow of rainwater to electrical components such as a compressor and a control board, it can be used in a wider installation environment, both indoors and outdoors.

  According to a second invention, in the first invention, the compressor chamber and the radiator chamber are independent by contacting at least a part of the outer peripheral portion of the opening surface with at least a part of the wall surface constituting the compressor chamber. It has become a space.

  Thereby, the compressor chamber and the radiator chamber are divided by the partition body, and at least a part of the outer peripheral portion of the opening surface of the partition body is in contact with at least a part of the wall surface constituting the compressor chamber, Rainwater that enters the radiator chamber from the outside does not flow into the compressor room, so the charging parts of the electrical parts such as the compressor and control board installed in the compressor room do not get wet, and There is no electrical leakage.

  In particular, at least a part of the outer peripheral portion of the opening surface of the partition body and at least a part of the wall surface constituting the compressor chamber are in contact with each other, and a portion other than the portion where the pipe of the piping hole connecting the compressor chamber and the radiator chamber passes is sealed. If this is the case, it is desirable that rainwater that has entered the radiator chamber from the outside of the cool box does not flow into the compressor chamber.

  According to a third invention, in the first or second invention, the space inside the partition is the radiator chamber, and the outer space is the compressor chamber.

  Thereby, compared with the case where a radiator room is arrange | positioned in the space outside a division body, a division body can be comprised more easily and a division body can be designed and manufactured at low cost. This is because the compressor chamber has electrical components such as a compressor and a control device, as well as a heat insulator, and more components than the radiator chamber. For this reason, when the compressor chamber and the radiator chamber are provided so that the space inside the partition body becomes the compressor chamber, the shape of the partition body becomes complicated.

  According to a fourth invention, in any one of the first to third inventions, the radiator is arranged so as to bisect the radiator chamber.

As a result, it is possible to provide a cool box that can be used in a wider range of installation environments, both indoors and outdoors.

  In a sixth aspect based on the fifth aspect, the opening is one opening facing the inlet port of the intake surface and the outlet port of the exhaust surface.

  As a result, even when rainwater enters the housing from outside the housing, the charged parts of electrical components such as compressors and control devices will not get wet, and the electrical components will not leak, so it can be used safely outdoors. In addition to being able to provide a cool box, there is only one opening for intake and exhaust, so the design and manufacture of the cool box outline can be performed more easily.

According to a seventh invention, in the fifth invention, the opening includes at least an intake port facing an introduction port of the intake surface and an exhaust port facing an exhaust port of the exhaust surface.
Is.

  As a result, even when rainwater enters the housing from outside the housing, the charged parts of electrical components such as compressors and control devices will not get wet, and the electrical components will not leak, so it can be used safely outdoors. In addition, it is possible to provide a cool box, and to reduce the opening area of the opening of the cool box outline, so that entry of foreign matter can be suppressed.

  In the following description, this arrangement is used as a representative example, but the cooling unit 17 may be arranged on either the front side, the left-right side, or the up-down direction side of the cool box 19.

  The cool box 19 includes a cooling chamber 11 that is provided between the cooling chamber door 16 and the cooling unit 17 and stores food and the like.

The cooling unit 17 includes a compressor 1, a radiator 2, a decompression device (not shown), and an evaporator 8. The compressor 1, the radiator 2, the decompression device (not shown), and the evaporator 8 are connected in a ring shape with a pipe (not shown) to constitute a refrigeration cycle circuit. A refrigerant is sealed in the refrigeration cycle circuit.
The cooling unit 17 further includes a box 3 opened on only one surface, two heat radiating fans 6, a cooling fan 13, a heat insulator 7, and a control device 20 that controls the operation of the cooling unit 17. . The box 3 is a compartment in the present invention.

  When viewed from the back side of the cool box 19, the compressor 1 is arranged on either side of the cooling unit 17 (on the left side in the present embodiment), and the box 3 and the heat insulator 7 are arranged on the other side. (Right side in the present embodiment).

  The heat insulator 7 is a box that is provided above the box 3 and has an opening on one side. The heat insulator 7 is made of foamed plastic, for example, polystyrene foam. The heat insulator 7 includes an evaporator 8 and a cooling fan 13 inside.

  In order to provide the evaporator 8 and the like inside, the heat insulator 7 can be divided into upper and lower parts on a surface perpendicular to the surface having the opening.

  The heat insulator 7 includes ribs that divide the space on the opening side of the evaporator 8, the space on the opposite opening side of the evaporator 8, and the space on the side of the evaporator 8. The space on the opening side of the evaporator 8 is a cold air blowing air passage 21, and the space on the side opposite to the evaporator 8 and the space on the side of the evaporator 8 is a cold air suction air passage 22.

  A temperature sensor 12 for detecting the indoor temperature of the cooling chamber 11 is provided in the cold air suction air passage 22. The temperature sensor 12 may be provided in the cooling chamber 11 or the cool air blowing air passage 21.

  The heat insulator 7 includes a communication hole on the side of the evaporator 8 that communicates the space in the heat insulator 7 with a compressor chamber 1a described later. The pipe connecting the compressor 1 and the evaporator 8 is passed through the through hole.

  The cooling unit 17 has a partial area between the compressor chamber 1a in which the compressor 1 and the control device 20 are arranged, and the radiator chamber 2a in which the radiator 2 and the radiating fan 6 are arranged in a box 3 Separated by Alternatively, the cooling unit 17 is completely separated by the box 3 into the compressor chamber 1a in which the compressor 1 and the control device 20 are disposed, and the radiator chamber 2a in which the radiator 2 and the heat radiation fan 6 are disposed. The compressor chamber 1a and the radiator chamber 2a are separate spaces.

  In addition, the partial region between the compressor chamber 1a and the radiator chamber 2a being separated by the box 3 means that the radiator 2 is surrounded by the wall surfaces of the box 3. Means.

  In the present embodiment, “the compressor chamber 1a and the radiator chamber 2a are independent spaces” means that any surface of the box 3 has a unit base of the cooling unit 17 or a cold insulation. The outer peripheral portion 3a of the opening surface of the box 3 and the cold storage outer shell 15 are in contact with each other when the other portion such as the outer shell 15 (corresponding to a wall surface constituting the compressor chamber described later) is not used. When the state or any surface of the box 3 is also used for other parts such as the unit base of the cooling unit 17 or the cool box outline 15, the outer peripheral portion 3a of the opening surface of the box 3 and the cool box outline 15 is in contact, and the box 3 is in contact with the bonding surface of another component.

  As a result, rainwater that has entered the radiator chamber 2a from the outside of the cool box does not flow into the compressor chamber 1a.

  In any of the above cases, the box 3 includes a piping hole 23 on the side surface on the compressor chamber 1a side. The piping connecting the compressor 1 and the radiator 2 is passed through the piping hole 23. The piping holes 23 are all completely closed using, for example, a heat insulating foam or putty except for a portion through which the piping passes.

  As a result, rainwater that has entered the radiator chamber 2a from the outside of the cool box does not flow into the compressor chamber 1a via the piping hole 23.

  In any case, the radiator 2 and the radiator fan 6 are all housed inside the opening surface of the box 3.

  The unit base is a plate on which components (for example, a compressor and a radiator) of the cooling unit 17 are installed.

  Next, the box 3 will be described in detail.

  The box 3 is a resin and is made of polypropylene (PP) in this embodiment, but may be other resins.

  The thickness of the box 3 is specifically about 1.5 to 2.5 mm, but even with a thickness of 1.5 mm or less, or 2.5 mm or more in consideration of the space where the box 3 can be installed. I do not care.

  The material of the box 3 is resin in the present embodiment, but may be sheet metal or fiber. Specifically, a member having a low moisture permeability is preferable.

  The shape of the box 3 may be one in which five surfaces other than the opening surface are covered, but when the bottom surface or side surface of the box 3 is also used with other parts such as the unit base of the cooling unit or the outer wall of the cool box, Anything other than the opening surface and a surface that is also used as another component can be used as the box 3.

  Specifically, in the case of sharing with other parts, the box 3 is covered with four or less surfaces, for example, four surfaces or three surfaces.

  In addition, when a part of surface of the box 3 is also used as the cold storage outer shell, an opening surface may be provided on the surface of the box 3 that is also used.

  At this time, there may be a plurality of opening surfaces of the box 3 as long as they are provided on a surface that is also used as the box 3 and a surface that faces the air inlet and outlet.

  Specifically, in the case where the side surface of the cool box outer wall and the side surface of the box 3 are also used, the surface (side surface) also used as the cool box outer shell, and the surface facing the air inlet and outlet And the case where the opening surface of the box 3 is provided.

  In this way, by using a part of the surface of the box 3 also as other parts, the box 3 can be configured with fewer members, and the box 3 can be manufactured at low cost.

  Further, the shape of the box 3 is not necessarily rectangular, and may be other shapes such as a sphere or a triangular pyramid as long as it has at least one opening surface.

  The radiator 2 is disposed substantially in the center so as to divide the radiator chamber 2a into two vertically, and one space serves as an intake portion 4 of the radiator 2 and the other space serves as an exhaust portion 5 of the radiator 2. Yes.

  Furthermore, both the intake surface 4a of the intake unit 4 of the radiator 2 and the exhaust surface 5a of the exhaust unit 5 are provided on the opening surface constituting the radiator chamber 2a.

  That is, the intake surface 4a and the exhaust surface 5a are provided on the same surface.

  The entire intake surface 4a is an air inlet, and the entire exhaust surface 5a is an air outlet. Alternatively, an air inlet may be provided in a part of the intake surface 4a, and an air outlet may be provided in a part of the exhaust surface 5a.

  It should be noted that the position of the radiator 2 in the substantially central position of the radiator chamber 2a means that when the radiator 2 is arranged in the radiator chamber 2a, the volume of the intake section 4 and the volume of the exhaust section 5 are , Refers to approximately equal positions.

  The opening surface of the box 3 is specifically a surface communicating with the outside air constituted by the outer peripheral portion 3a of the opening surface of the box and the wall surface constituting the compressor chamber, and the intake surface and the exhaust gas. It is the same surface as the surface having the surface.

  The wall surface constituting the compressor room refers to the wall surface of the casing surrounding the compressor. Specifically, the A surface (side surface of the housing) and the B surface (top surface of the housing) shown in FIG. , C surface (side surface of the housing), D surface (bottom surface of the housing), and E surface (back surface of the housing).

  Further, as shown in FIG. 6, the shape of the box 3 is shown as a box 3 having a flange on the outer peripheral portion 3a of the opening surface of the box, but as shown in FIG. 7, the outer peripheral portion of the opening surface of the box is shown. Even if 3a does not have a flange, it can be used as the configuration of the first embodiment and the second and third embodiments shown below.

  In the following description, a case with a flange is illustrated as a representative example of the box 3.

  Next, the cooling operation of the cooling unit 17 provided in the cool box 19 having the above configuration will be described.

  The refrigeration cycle is activated by operating the compressor 1, the heat radiating fan 6, and the cooling fan 13 in accordance with a signal from the control device 20. The high-pressure and high-temperature refrigerant compressed by the compressor 1 flows into the radiator 2.

  In the heat radiator 2, as shown by the arrow X in FIG.

  Specifically, in the radiator chamber 2a, air is sucked into the radiator chamber 2a from the intake section 4 and passes through the radiator 2, as shown by an arrow X in FIG. Air is exhausted from the exhaust part 5.

The refrigerant radiated by the radiator 2 becomes a low-pressure and low-temperature refrigerant by the decompression device and flows into the evaporator 8.
In the evaporator 8, as shown by an arrow Y in FIG. 4, a cooling (endothermic) action is performed while obtaining an airflow effect.

  In the cooling chamber 11 for storing food or the like, the cooling fan 13 sucks air in the cooling chamber 11 from the cold air suction air passage 22 of the evaporator 8 and passes through the evaporator 8, so that the cold air is blown out of the cold air. The air is circulated from the air passage 21 into the cooling chamber 11 to be cooled.

  Thereby, stored items such as food stored in the cooling chamber 11 storing food and the like can be cooled and stored.

  The control unit 20 controls the operation of the compressor 1, the cooling fan 13, and the like based on the temperature of the cooling chamber 11 detected by the temperature sensor 12. Maintained in the temperature range.

  Here, as in the conventional case, when using a cool box with a built-in cooling unit composed of a compressor room and a radiator room as a delivery box, if it is installed outdoors, rainwater, etc. , It enters the inside of the cool box through the air intake or exhaust section provided for the ventilation of the cooling unit's radiator from the outside of the cool box, and the electrical components such as compressors and control devices There was a possibility that the live parts would get water and the electrical components would leak.

  For this reason, it has been impossible to install a cold storage with a built-in cooling unit outdoors.

  However, when the configuration of the first embodiment of the present invention is used, as shown in FIGS. 2 and 3, the intake surface 4 a and the exhaust portion of the intake portion 4 provided in the radiator chamber 2 a from outside the housing of the cool box 19. The rainwater that has passed through the exhaust surface 5 a of 5 and entered the housing of the cool box 19 is separated by a box 3 at least in a partial region between the compressor chamber 1 a and the radiator chamber 2 a.

  Thereby, the inflow of the rainwater from the radiator room 2a to the compressor room 1a is inhibited.

  Therefore, the inflow of rainwater from the radiator chamber 2a to the compressor chamber 1a is reduced, and rainwater intrudes into the charging parts of the electrical components such as the compressor 1 and the control device 20 provided in the compressor chamber 1a. Can be suppressed.

  In addition, when the compressor chamber 1a and the radiator chamber 2a are completely separated and the compressor chamber 1a and the radiator chamber 2a are independent from each other, the rainwater that has entered the casing of the cool box 19 1a and the radiator chamber 2a are completely separated by the box 3, so that they do not flow into the compressor chamber 1a and pass again through the intake surface 4a of the intake unit 4 and the exhaust surface 5a of the exhaust unit 5. Then, it is discharged out of the casing of the cool box 19.

  Therefore, there is no fear that water will be applied to the charging parts of the electrical components such as the compressor 1 and the control device 20 in the compressor chamber 1a, and the electrical components will not leak.

  Therefore, even if the cool box 19 is installed outdoors as a delivery box, the cooling unit 17 can be used safely.

  Here, in FIG. 1, FIG. 2, FIG. 3, FIG. 4, in order to more easily design and manufacture the box 3, the space inside the box 3 is the radiator chamber 2a and the outside space is the compressor chamber 1a. It is said.

  The compressor chamber 1a includes electrical components such as the compressor 1 and the control device 20 as well as a heat insulator 7 and the like, and has more components than the radiator chamber 2a. Therefore, when the compressor chamber 1a and the radiator chamber 2a are provided so that the space inside the box 3 becomes the compressor chamber 1a, the shape of the box 3 becomes complicated, and the design and manufacture are It becomes a big burden in each process.

  Therefore, in order to more easily design and manufacture the box 3, the radiator chamber 2a and the compressor chamber 1a are arranged such that the space inside the box 3 is the radiator chamber 2a and the outside space is the compressor chamber 1a. The following arrangement is preferable.

  In addition, when the space inside the box 3 is the compressor chamber 1a and the space outside is the radiator chamber 2a, the configuration of the first embodiment can be used.

  In the following description, an arrangement in which the space inside the box 3 is the radiator chamber 2a and the outside space is the compressor chamber 1a is used.

  Next, the second and third internal structures of the radiator chamber of the first embodiment will be described with reference to FIGS. 8, 9, 10, 11, and 12.

  FIG. 8 is a rear perspective view showing the second configuration of the cooling unit of the cool box in Embodiment 1 of the present invention, and FIG. 9 shows the inside of the radiator in the cooling unit of the cool box in Embodiment 1 of the present invention. It is a perspective view showing the 2nd composition of.

  FIG. 10 is a rear perspective view showing a third configuration of the cooling unit of the cool box in Embodiment 1 of the present invention, and FIG. 11 shows the inside of the radiator in the cooling unit of the cool box in Embodiment 1 of the present invention. FIG. 12 is a perspective view showing a third configuration of the radiator interior of the cooling unit of the cool box according to Embodiment 1 of the present invention.

  In the second configuration, with respect to the arrangement of the radiator 2 and the radiator fan 6 in the radiator chamber 2a, the radiator 2 and the radiator fan 6 are arranged in the radiator chamber 2a as shown in FIGS. Therefore, the left and right are arranged in half.

  Further, in the third configuration, the arrangement of the radiator 2 and the radiator fan 6 in the radiator chamber 2a is radiated in the radiator chamber 2a as shown in FIGS. The device 2 and the heat dissipating fan 6 are arranged so as to be divided into two parts.

  In any configuration, both the intake surface 4a of the intake unit 4 of the radiator 2 and the exhaust surface 5a of the exhaust unit 5 are provided on the opening surface constituting the radiator chamber 2a.

  That is, the intake surface 4a and the exhaust surface 5a are provided on the same surface.

  Further, at this time, in both configurations, the compressor is similar to the first configuration in which the inside of the radiator chamber 2a shown in FIGS. 2 and 3 is divided into two parts by the radiator 2 and the radiator fan 6. 1. At least a partial region between the compressor chamber 1a in which the control device 20 and the like are disposed, and the radiator chamber 2a in which the radiator 2 and the radiator fan 6 are disposed is separated by a box 3, or 3, the compressor chamber 1a in which the compressor 1, the control device 20 and the like are arranged, and the radiator chamber 2a in which the radiator 2 and the radiator fan 6 are arranged are divided into the compressor chamber 1a and the radiator chamber. Each of 2a is an independent space.

  Even when at least a partial region between the compressor chamber 1a and the radiator chamber 2a is separated by the box 3, the compressor chamber 1a and the radiator chamber 2a are independent spaces. Even when the cooling unit 17 is, the radiator 2 and the radiator fan 6 are all housed inside the opening surface of the box 3.

  Both the second configuration and the third configuration have the same effects as the first configuration.

  However, in the third configuration, when the open surface of the rectangular box 3 disposed on the back side of the cool box 19 is used as a reference, the radiating fan 6 is on the near side and the radiator 2 is on the far side. By arranging, the replacement work when the heat radiating fan 6 breaks down can be performed more easily, and the maintainability can be improved.

  In the first configuration or the third configuration, the heat radiating fan 6 is arranged so that the intake portion 4 provided for ventilation of the radiator 2 is on the lower side and the exhaust portion 5 is on the upper side. 3 or as shown by an arrow X in FIG. 11 and FIG. 12, the outside air is sucked from the lower side of the radiator 2 and the air warmed by passing through the radiator 2 is discharged to the upper side of the radiator 2. It is more preferable that fresh air is easily sucked into the radiator chamber 2a.

  In addition, as long as it is the arrangement | positioning which suck | inhales external air from the lower side of the heat radiator 2, and discharges the air warmed by passing the heat radiator 2 to the upper side of the heat radiator 2, arrangement | positioning of the radiator chamber 2a 11, the radiator 2 and the radiator fan 6 are arranged on the lower side in the radiator chamber 2a.

FIG. 21 is a perspective view showing a third configuration inside the heat insulator of the cooling unit of the cool box in Embodiment 2 of the present invention.

  13, 16, and 19 are rear perspective views in which a part of the heat insulator 7 is omitted in order to illustrate the evaporator-side drainage channel 9 and the radiator chamber box-side drainage channel 10 in an easy-to-understand manner. FIG.

  First, the configuration of the second embodiment will be described with reference to FIG. 13, FIG. 14, and FIG.

  13, 14, and 15, the cooling unit 18 according to the second embodiment includes an evaporator-side drainage channel 9 on the bottom surface of the heat insulator 7, and a radiator chamber box-side drainage channel on the top surface of the box 3. 10 is provided.

  The evaporator-side drainage channel 9 provided in the heat insulator 7 and the radiator chamber box-side drainage channel 10 provided in the box 3 are continuously formed as a through hole penetrating the heat insulator 7 and the box 3. It has become the arrangement. That is, the inside of the heat insulator 7 and the inside of the radiator chamber 2a communicate with each other through this through hole.

  At this time, even if a tube or the like is inserted into the evaporator-side drainage channel 9 and the radiator chamber box-side drainage channel 10, it can be used as the configuration of the second embodiment.

  Here, in a general cooling unit, when the refrigeration cycle is activated, condensed water is generated on the surface of the evaporator. The condensed water generated on the surface of the evaporator is once stored in a drain pan or the like and then used with a tube or the like. Pour into a drain pan located around the radiator and evaporate in the drain pan using heat from the cooling unit, wind from the cooling fan, or an evaporator.

  Alternatively, after condensing once in a drain pan or the like, the condensed water is treated by draining it out of the case of the cool box using a tube or the like.

  However, when Embodiment 2 of the present invention is used, as shown in FIGS. 13, 14, and 15, the condensed water generated on the surface of the evaporator 8 is removed from the evaporator-side drainage channel provided in the heat insulator 7. 9 and the radiator chamber box-side drainage channel 10 provided in the box 3, and flows into the radiator chamber 2a.

  Thereafter, the air passes through the intake surface 4a of the intake unit 4 and the exhaust surface 5a of the exhaust unit 5 in the radiator chamber 2a, and is drained out of the casing of the cool box 19.

  At this time, the compressor chamber 1a and the radiator chamber 2a are completely separated by the box 3, and the condensed water flowing into the radiator chamber 2a does not flow into the compressor chamber 1a.

  Therefore, the dew condensation water generated on the surface of the evaporator 8 does not wet the charged parts of the electrical components such as the compressor 1 and the control device 20 in the compressor chamber 1a, and the compressor 1 and the control device 20 Electrical components such as will not leak.

  Therefore, the cooling unit 18 of the second embodiment can drain the condensed water generated on the surface of the evaporator 8 to the outside of the housing of the cool box 19 more easily than a general cooling unit.

  Further, since a drainage member such as a tube is not necessary, the cooling unit can be configured in a smaller space than a general cooling unit.

  Furthermore, by not using a member for drainage such as a tube, the cooling unit can be manufactured at a lower cost than a general cooling unit.

  Moreover, about the arrangement | positioning which divides the inside of the heat radiator chamber 2a into right and left or the front and back by the heat radiator 2 and the heat radiating fan 6, as shown in FIG. 16, FIG. 17, FIG. 18, FIG. The evaporator side drainage channel 9 and the radiator chamber box side drainage channel 10 are provided above the vertical projection surface of the radiator 2.

  Thereby, the low-temperature dew condensation water generated on the surface of the evaporator 8 passes through the evaporator-side drainage channel 9 and the radiator chamber box-side drainage channel 10, is directly dropped onto the radiator 2, and wets the radiator 2. The wet heatsink 2 is exposed to the outside air taken in by the action of the heat radiating fan 6 to promote the heat radiation of the heatsink 2, and the evaporator side drainage channel 9 and the radiator chamber box side drainage channel 10 are connected to the exhaust unit. Compared with the case where it is provided above 5, the heat dissipation effect of the radiator 2 can be further enhanced.

  At this time, even when the evaporator-side drainage channel 9 and the radiator chamber rectangular drainage channel-side drainage channel 10 are provided above the intake portion 4 in the radiator chamber 2a, the evaporator-side drainage channel 9, the heat dissipation The effect similar to the case where the chamber box side drainage channel 10 is provided above the vertical projection surface of the radiator 2 can be obtained.

  This is because the condensed water dropped on the intake section 4 is also carried to the radiator 2 by the action of the heat radiating fan 6.

  13, 16, and 19, the internal structure of the cooling unit 18 according to the second embodiment includes a wall surface including the radiator chamber box side drainage channel 10 of the box 3 and the evaporator side of the heat insulator 7. The wall surface provided with the drainage channel 9 has an internal structure in contact therewith.

However, the wall surface provided with the radiator chamber box side drainage channel 10 of the box 3 and the wall surface provided with the evaporator side drainage channel 9 of the heat insulator 7 are not necessarily in contact with each other. The path 9 and the radiator chamber box-side drainage path 10 provided in the box 3 are connected by a tube or the like, or the box 3 and the heat insulator 7 are integrally molded, and penetrate the integrally molded structure. If it is the structure which has the drainage channel for the waste_water | drain which connects the inside of the box 3 and the inside of the heat insulation body 7 using methods, such as making a hole, it will use as a structure of the cooling unit 18 of this Embodiment 2. FIG. Can do.

(Embodiment 3)
Hereinafter, the third embodiment of the present invention will be described, but a part of the description overlapping with the first and second embodiments is omitted, and the same parts as the first and second embodiments or Corresponding parts are denoted by the same reference numerals.

  FIG. 22 is a rear perspective view illustrating the configuration of the cool box outline according to the third embodiment of the present invention, and FIG. 23 is a rear perspective view illustrating the second configuration of the cool box outline according to the third embodiment of the present invention. .

  First, the configuration and effects of the third embodiment of the present invention will be described with reference to FIG.

  The cool box 19 according to the third embodiment includes a cool box outline 15 provided with a vent 14 for intake and exhaust, the cooling unit 17 described in the first embodiment, or the cooling described in the second embodiment. A unit 18 is provided.

  In addition, the air inlet 14 for intake and exhaust provided in the cool box outer shell 15 is provided at a position facing the intake surface 4 a of the intake unit 4 and the exhaust surface 5 a of the exhaust unit 5.

  In other words, the intake / exhaust vent (opening) 14 provided in the cool box outer shell 15 serves as both an intake port and an exhaust port.

  A ventilation port (opening) 14 for intake and exhaust faces the intake surface 4a and the exhaust surface 5a of the radiator chamber.

  Here, in a general cool box, an air inlet and an exhaust port provided in the cool box outline are provided on separate wall surfaces (different wall surfaces) of the cool box outline. In addition, the cooling unit built in the cool box has not been sufficiently studied for rainwater countermeasures, and the inside of the cool box's housing can be passed from the outside of the cool box's housing through the intake and exhaust ports provided in the cool box's outer shell. Rainwater that has entered may wet the charging parts of electrical components such as compressors and control devices, and may cause electrical components to leak.

  For this reason, a general cold storage where the intake and exhaust ports are provided on separate wall surfaces of the cold storage enclosure, and the built-in cooling unit does not have sufficient rainwater countermeasures, is used as a delivery box installed outdoors. Cannot be used.

  However, by using the configuration of the third embodiment of the present invention, rainwater that has entered through the air vent 14 for intake and exhaust provided in the cool box outer shell 15 passes through the radiator chamber 2a, and again, It is discharged from the vent 14 for intake and exhaust.

  At this time, rainwater is blocked by the box 3 separating the compressor chamber 1a and the radiator chamber 2a and cannot enter the compressor chamber 1a.

  Therefore, there is no fear that the charging parts of the electrical components such as the compressor 1 and the control device 20 in the compressor chamber 1a get wet, and there is no fear that the electrical components leak.

  Therefore, the cool box 19 can be used as a delivery box installed outdoors.

  In other words, the opening is one opening facing the inlet port of the intake surface and the outlet port of the exhaust surface.

  As a result, even when rainwater enters the housing from outside the housing, the charged parts of electrical components such as compressors and control devices will not get wet, and the electrical components will not leak, so it can be used safely outdoors. In addition to being able to provide a cool box, there is only one opening for intake and exhaust, so the design and manufacture of the cool box outline can be performed more easily.

  Next, the second configuration and effect of the third embodiment of the present invention will be described with reference to FIG.

  The cool box 19 according to the second configuration of the third embodiment includes the cool box outer shell 15 provided with both the intake port 14a and the exhaust port 14b for ventilation on one surface, and the first embodiment described in the first embodiment. The cooling unit 17 or the cooling unit 18 described in the second embodiment is provided.

  Further, the air inlet 14 a provided in the cool box outer shell 15 is provided at a position facing the air intake surface 4 a of the air intake portion 4.

  Further, the exhaust port 14 b provided in the cool box outer shell 15 is provided at a position facing the exhaust surface 5 a of the exhaust unit 5.

  That is, there are at least two intake ports 14a (openings) and exhaust ports (openings) 14b provided in the outer wall of the cool box.

  The intake port 14a (opening) and the exhaust port (opening) 14b are opposed to the intake surface 4a and the exhaust surface 5a of the radiator chamber.

  Thereby, the rainwater which flowed in from the inlet port 14a and the exhaust port 14b provided in the cool box outer shell 15 passes through the radiator chamber 2a, and is again discharged from the inlet port 14a and the exhaust port 14b.

  At this time, rainwater is blocked by the box 3 separating the compressor chamber 1a and the radiator chamber 2a and cannot flow into the compressor chamber 1a, as in the configuration shown in FIG.

  Therefore, the configuration in which both the air inlet 14a and the air outlet 14b for ventilation are provided in the cool box outer shell 15 on one surface as shown in FIG. 23 is the same as that shown in FIG. The same effect as the structure provided in the outer shell 15 can be obtained.

  In addition, the configuration in which both the intake port 14a and the exhaust port 14b for ventilation are provided in the cool box outer shell 15 on one surface as shown in FIG. 23 is the cold insulation of the ventilation port 14 shown in FIG. Compared with the structure provided in the outer shell 15, the intrusion of foreign matter can be suppressed by reducing the opening area.

  In other words, the opening has at least an intake port facing the introduction port of the intake surface and an exhaust port facing the discharge port of the exhaust surface.

  As a result, even when rainwater enters the housing from outside the housing, the charged parts of electrical components such as compressors and control devices will not get wet, and the electrical components will not leak, so it can be used safely outdoors. In addition, it is possible to provide a cool box, and to reduce the opening area of the opening of the cool box outline, so that entry of foreign matter can be suppressed.

  In the configuration shown in FIG. 23, the intake port 14 a provided in the cool box outer shell 15 is positioned opposite to the intake surface 4 a of the intake unit 4, and the exhaust port 14 b is opposed to the exhaust surface 5 a of the exhaust unit 5. As long as there are a plurality of intake ports 14a and exhaust ports 14b for ventilation, the configuration of the third embodiment can be used.

As described above, the cooling unit according to the present invention is
Suppressing rainwater intrusion into electrical components such as compressors and control bases makes it possible to use it in a wider range of installation environments, both indoors and outdoors, so it can be applied to cool boxes such as delivery boxes. .
