Description

  The present invention relates to a vehicle temperature regulator mounted on a vehicle or the like.

As related to this type of prior art, as described in Japanese Patent Application Laid-Open No. H10-228707, “a cold / hot storage control device for automobiles” has been proposed. As shown in FIG. 5, a case 101 includes a blower 102, an evaporator 103, and a refrigerator 104. Refrigerant is supplied to the evaporator 103 from a compressor driven by an automobile engine (not shown), and air is sent from the blower 102 through the upper air passage 105 of the evaporator 103, so that air is exchanged by heat exchange in the upper air passage 105. The refrigerated product such as food and drink in the refrigerator 104 is kept cold by blowing cool air from one outlet 106 to the top of the refrigerator 104. Next, air is returned from the refrigerator 104 to the blower 102 through the lower portion of the evaporator 103.
In addition, as another conventional technique, as shown in FIG. 6, a fan 111 is provided on one side of the refrigerator 110, and an evaporator 112 is disposed above the fan 111, An example is one in which air is sucked in from the lower portion by the blower 111 and cooled by the evaporator 112, and then cool air is blown out from one outlet 113 to the upper portion of the refrigerator 110.

  However, in the prior art described in Patent Document 1, since the cold air is blown out from the outlet 106 at only one place into the refrigerator 104, the flow path through which the cold air passes in the refrigerator 104 is only in one direction. However, since the state of the cold air blown out to each part in the refrigerator 104 is not uniform, there is a problem in that the temperature at which the refrigerated product is kept at each part in the refrigerator 104 varies. Further, when there is a refrigerated object in the vicinity of the air outlet 106, the refrigerated object obstructs the flow of the cold air. Further, the conventional technique shown in FIG. 11 has the same problem.

  The present invention has been made in consideration of the above-described prior art, and its purpose is to improve the temperature control performance when storing the stored items in the inner case, and to control the temperature at which each stored item is stored. An object of the present invention is to provide a vehicle temperature regulator that can reduce variations.

  In order to achieve the above object, the invention of claim 1 includes an outer case forming an outer shell, an inner case provided inside the outer case and forming a temperature control chamber therein, and the outer case and the inner case. A temperature regulator for a vehicle having a heat insulating portion interposed therebetween, and a temperature control wind from the air flow path to the temperature control chamber on the inner case and a ventilation path between the heat insulation section and the inner case. A plurality of outlets for blowing out are provided.

  Invention of Claim 2 is the temperature regulator for vehicles of Claim 1, Comprising: The said ventilation path between the bottom face of the said inner case and the said heat insulation part, A blower outlet in the bottom face of the said inner case, A drainage drain hole communicating with the air passage is provided at the bottom of the outer case.

  According to the first aspect of the present invention, the temperature adjustment air is supplied via the air passage between the heat insulating portion in the outer case and the inner case, and the temperature adjustment is performed from the plurality of outlets to the temperature adjustment chamber in the inner case. Since the air is blown out, multiple flow paths through which the temperature-controlled air flows are formed inside the inner case, and the temperature-controlled air flows through a relatively large number of locations inside the inner case, thereby blowing out the temperature-controlled air to each stored item. The state can be made uniform.

  In addition, even if there are stored items in the vicinity of some air outlets and the flow of temperature control air is obstructed, temperature control air is blown out from the other air outlets to the inside of the inner case. be able to. Thereby, while being able to improve the temperature control performance at the time of storing a store within an inner case, the dispersion | variation in the temperature which stores each store can be reduced.

  According to the invention of claim 2, since the temperature-controlling air outlet and the drainage drain hole communicate with each other, the temperature control performance is ensured without complicating the configuration of the entire apparatus, Condensed water and liquid leaking from the storage can be discharged out of the warehouse.

  Hereinafter, a vehicle temperature regulator according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a plan view showing a vehicle temperature regulator according to an embodiment of the present invention, FIG. 2 is a sectional view taken along line AA in FIG. 1, and FIG. 3 is a sectional view taken along line BB in FIG. 4 is an enlarged cross-sectional view of a portion C in FIG. In FIG. 1, the inside of the inner case is illustrated with the upper portion of the inner case removed. Moreover, the flow of air is shown by the arrows in FIGS.

  As shown in FIGS. 1 to 4, the vehicle temperature regulator 1 of the present embodiment is provided in an outer case 2 that forms an outer shell, and in the outer case 2, and forms a temperature control chamber 12. Inner case 3 for storing stored items (not shown) in temperature control chamber 12, heat insulating portion 4 interposed between outer case 2 and inner case 3, and air sucked in from upper inlet 5 of inner case 3 circulates. And an evaporator 7 interposed between the upper suction port 5 and the blower 6.

  Between the bottom part of the four side surfaces 3a to 3d of the inner case 3 and the heat insulating part 4, and between the bottom surface 3e of the inner case 3 and the heat insulating part 4, an air passage through which the temperature-controlled air from the blower 6 is blown. 8 is formed. And the blower outlets 9a-9e which blow off air from the said ventilation path 8 inside the inner case 3 are provided in the side surfaces 3a-3d and the bottom face 3e near the bottom face of the inner case 3.

  The air outlets 9 a to 9 d on the side surfaces in the vicinity of the bottom surface of the inner case 3 are arranged at the same height as the blower 6 and on the four side surfaces 3 a to 3 d of the inner case 3.

  A drain drain hole 10 is provided at the bottom of the outer case 2. The drain hole 10 communicates with the inside of the inner case 3 through the air outlet 9e provided in the bottom surface 3e of the inner case 3 and the air passage 8, and leaks from condensed water in the temperature control chamber 12 and stored items. The discharged liquid is discharged out of the warehouse. When a large amount of liquid flows into the temperature control chamber 12, the outside of the chamber is discharged from the outlets 9 a to 9 d provided on the side surfaces 3 a to 3 d of the inner case 3 through the air passage 8 and the drainage drain hole 10. The liquid is discharged to

  In this embodiment, after the air is sucked from the temperature control chamber 12 through the suction port 5 by the operation of the blower 6 and cooled by the evaporator 7, the cool air as the temperature control air from the blower 6 is converted into the heat insulating portion 4. It supplies via the ventilation path 8 between the inner case 3 and the cold air is blown out into the temperature control chamber 12 from the several blower outlets 9a-9d. As a result, a plurality of flow paths through which the cool air passes inside the inner case 3 are formed, and the cool air flows through a relatively large number of locations inside the inner case 3, thereby achieving a uniform state in which the cool air is blown to each stored item. be able to. Further, even if there is a stored item such as a drink near the blowout port 9a and the flow of the cold air is obstructed, the stored air can be reliably discharged by blowing the cold air from the other blower ports 9b to 9d to the temperature control chamber 12. Can be stored. Further, since there is no condensed water during normal use, cold air is also blown into the temperature control chamber 12 from the outlet 9e on the bottom surface 3e of the inner case 3.

  In the embodiment configured as described above, it is possible to improve the temperature control performance when storing the stored items in the temperature control chamber 12, and it is possible to reduce variations in the temperature at which the stored items are stored. Moreover, since the heat insulation effect can be improved against the heat damage from the lower part of the vehicle by turning the cool air to the bottom surface of the inner case 3 through the air passage 8, the temperature control when storing the stored item also in this respect Performance can be improved.
