Description

[Detailed Description of the Invention] The present invention relates to an on-vehicle refrigerator for cooling objects to be cooled, such as canned drinking water.

Conventional refrigerators of this type are, for example,
As described in Publication No. 21307, many vehicles cool canned drinking water and the like in the refrigerator by introducing cold air cooled by a vehicle air conditioner into the refrigerator.

However, in seasons other than summer, there is little need to cool and store canned drinking water and the like in cars, so there is a problem that refrigerators are rarely used outside of summer.

Therefore, the present inventors considered using the refrigerator as a storage space when there is no need to cool canned drinking water or the like inside the refrigerator.

However, with the above-mentioned conventional products, when the air conditioner is activated, cold air always circulates inside the refrigerator, so when the refrigerator is used as a storage space, the cold air comes into contact with the items inside the refrigerator, causing dew condensation on the surfaces of the items. There is a problem that arises. There is also the problem that the air conditioning capacity is reduced due to the wasteful circulation of cold air into the refrigerator.

The present invention has been made in view of the above points, and an object of the present invention is to easily block the inflow of cold air with a simple mechanism when not being used as a refrigerator, so that it can be used satisfactorily as a storage space.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

First, with reference to FIG. 1, the entire air conditioning system of a vehicle in which a vehicle refrigerator 1 according to an embodiment of the present invention is installed will be briefly described. The air conditioning system includes a duct 2, a blower 3 that introduces air from inside the car and/or outside the car into the space inside the duct 2,
Cooler evaporator 4 located in the interior space of the duct 2
and a heater heat exchanger 5 disposed downstream of the evaporator 4, and a solid line to adjust the ratio of the amount of air passing through the heater heat exchanger 5 and the amount of air passing through the bypass path 5a. It has an air mix damper 6 that is movable between a fully closed position shown by and a fully open position shown by a broken line. Part of the air that has passed through the cooler evaporator 4 passes through the heater heat exchanger 5 depending on the position of the air mix damper 6, and the rest flows downstream through the bypass path 5a of the heater heat exchanger 5. . The air that has passed through the heater heat exchanger 5 and the air that has bypassed the heater heat exchanger 5 are mixed in the mixing chamber 7, and the air is adjusted to have an appropriate temperature. Of course, if the damper 6 is in the fully closed position shown by the solid line, all of the air that has passed through the evaporator 4 will be transferred to the heater heat exchanger 5.
If the damper 6 is in the fully open position shown by the broken line, the evaporator 4
All of the air that has passed through passes through the heater heat exchanger 5 and flows into the mixing chamber 7. The air in the mixing chamber 7 is discharged into the vehicle interior through a vent outlet 8, a defroster outlet 9, and a heater outlet 11, respectively. Incidentally, the number 12 in FIG. 1 indicates a vehicle-side dart board, which partitions the engine frame 13 and the vehicle interior 14. The refrigerator 1 of the present invention is installed in a vehicle interior between a console box 50 having a transmission lever and a heater unit of an air conditioner. 51 is a driver's seat, and 52 is a passenger seat. As shown in FIG. 1, the refrigerator 1 according to the embodiment of the present invention is connected to the air conditioning system through a cold air intake duct 15 and a cold air outlet duct 16. More specifically, the cold air introduction duct 15 has one end that opens immediately downstream of the cooler evaporator 4 and the other end that is connected to the refrigerator 1. The cooled air is guided into the refrigerator 1. The cold air outflow duct 16 has one end connected to the refrigerator 1 and the other end opened to the air suction part, ie, the negative pressure part, of the Sirotskov fan 3a of the blower 3.
The air inside is made to flow out to the negative pressure part of the Sirotskov fan 3a.

As is clear from the above, the cold air immediately after the evaporator 4 passes through the cold air introduction duct 15, flows into the refrigerator 1, passes through the inside of the refrigerator, and then flows into the outflow duct 1.
6 to the negative pressure part of the Sirotskov fan 3a,
In this way, the air circulates and flows.

2 to 4 show in detail the on-vehicle refrigerator 1 according to an embodiment of the present invention. The refrigerator 1 has a refrigerator main body part 31 and an opening/closing lid part 33 that cooperates with the main body part 31 to define a storage space 32 inside. It has a wall structure, and its lid part 33 is connected to the main body part 3.
1 by an integrally molded thin resin hinge 33a, and is pivotable between a closed position shown by a solid line in FIG. 2 and an open position shown by an integral chain line. Further, a handle portion 33b is integrally molded on the lid portion 33. Container 34 for objects to be cooled, such as cans and bottle paper packs
is adapted to be accommodated within the storage space 32.

A bracket 3 is attached to the bottom of the main body 31 of the refrigerator 1.
5 is fixed with a screw 35a, a bracket 35 is fixed with a screw 35a, and the bracket 35 is fixed to a vehicle body 36 with a bolt and nut assembly 37.

The cold air introduction duct 15 shown in FIG.
As shown in FIG. 2, it opens from the back of the main body 31 to the bottom wall, and the cold air outflow duct 16
is the rear wall 41 of the main body 31 that is remote from the lid 33
It is open to

A cold air inlet 38 is provided in the main body 31 in close proximity to the opening/closing lid 33 so as to be directly connected to the open end of the cold air inlet duct 15, and a circular shape is formed on the upper surface of the cold air inlet 38. A recess 39 is formed, and this circular recess 39 has a ring-shaped projection 39a on its inner peripheral wall.
A circular opening/closing damper 40 made of resin is rotatably fitted and held in a by utilizing the elasticity of the resin. As shown in detail in FIGS. 5a, b, and c, this damper 40 has a semicircular opening 40a, a handle portion 40b for manual operation, and a ring-shaped groove 40c on the outer periphery. Reference numeral 42 denotes a tray for holding the container 32, which is molded from an elastic resin such as polypropylene, and this tray 42 has an elastic presser piece 42a, a support leg 42b, and a fixed boss piece, as detailed in FIGS. 6a and 6b. 42c, stopper portion 42d, etc. are integrally molded. The fixed boss piece 42c has a protrusion 42e at its lower end, and the saucer 42 is removably fixed to the main body 31 by pressing and inserting the protrusion 42e into the recess 43 of the main body 31 using the elasticity of the resin. ing.

The container 34 of the object to be cooled is inserted into the recess 42f while elastically deforming the elastic holding piece 42a. Movement of the container 34 in the longitudinal direction is prevented by the elastic presser piece 42a and the stopper part 42d, and movement to the left and right is prevented by the concave shape of the recessed part 42f. Thereby, generation of abnormal noise due to movement of the container 34 can be prevented.

In the refrigerator configured as described above, when cooling the container 34 of the object to be cooled placed inside the refrigerator, the opening/closing damper 40 is operated to the illustrated position in FIGS. 2 and 4. As a result, the cold air flowing through the cold air introduction duct 15 flows into the storage space 32 through the cold air introduction port 38 and the opening 40a of the damper 40 as shown by the arrow in FIG. 2, and is stored in the storage space 32. It flows around the container 34 and enters the cooling outflow duct 16, thus cooling the contents within the container 34.

On the other hand, if there is no need to cool the objects to be cooled in the storage space 32, open the opening/closing lid 33 and directly manually operate the opening/closing damper 40 to rotate it 180 degrees from the illustrated position and open the cold air inlet. Block 38.
This prevents cold air from being introduced into the refrigerator, thereby improving the cooling capacity of the air conditioner and preventing dew condensation from forming on the surfaces of the articles in the storage space 32. By removing the saucer 42 and taking it outside, the space 32 can be effectively used as a storage space.

Note that, without being limited to the above-mentioned example,
The present invention can be implemented in various ways, and the opening/closing damper 40 is not limited to a circular shape, but can also be easily implemented in other shapes such as a fan shape. If there is, it can be anything.

Further, in the above-mentioned embodiment, the case where the saucer 42 is provided has been described, but the saucer 4 is not necessarily necessary, and the article to be cooled may be directly stored in the space 32 by eliminating the saucer 42. Good too.

As described above, according to the present invention, the opening/closing lid part 3
3, and the cold air inlet 38 is opened and closed by an opening/closing damper 40 having a handle part 40b. It has an extremely simple structure without the need for operating links, levers, or other parts, can block the introduction of cold air, and has the great effect of being easily used as a storage space. .

Furthermore, since the refrigerator main body of the present invention is connected to a vehicle air conditioner using a cold air inflow duct and a cold air outflow duct, the refrigerator main body must be located at a location separate from the vehicle air conditioner. I can do it. Therefore, in the present invention, the refrigerator can be disposed, for example, between the console box and the heater unit, and the refrigerator can be disposed at a convenient position.

Furthermore, in the refrigerator of the present invention, the cold air inlet is provided at the bottom of the refrigerator main body, while the cold air outlet is provided at the upper part of the refrigerator main body at a position almost opposite to the cold air inlet. The distribution of cold air flow within the refrigerator body becomes extremely good. In other words, warm air generally accumulates above the refrigerator body, but in the refrigerator of the present invention, the cold air outlet is provided in the upper part of the refrigerator body, so this warm air does not accumulate. This results in good derivation without having to do anything.
Furthermore, since the cold air inlet and the cold air outlet are provided at substantially opposite positions, the cold air flows evenly within the refrigerator main body, making it possible to improve the cooling efficiency of the refrigerator as a whole.
