Description

[Detailed Description of the Invention] The present invention relates to a cool box, and particularly to a cool box that guides cold air from an air conditioner to a glove box or a box-type undertray in an instrument section of a vehicle.

Some vehicles are equipped with cool boxes, such as glove boxes, that can direct cold air into article storage boxes to cool the items stored inside.
A conventional example of such a cool box is shown in FIG. 1, for example. The cool box 20 is composed of a box main body 21 and a lid 22 rotatably attached to the box main body 21. One end of the cool box 20 is connected to the box main body 21 and is connected to a part of the air distribution duct 5 of the air conditioner 1. It is communicated with the air distribution duct 5 by a hose 16 whose other end is connected to the branch passage 15 formed. The air conditioner 1 used here has an air intake box 2 with an inside/outside air switching door 6 and a blower 7 placed inside, a cooler unit 3 with a built-in evaporator 8, and an air mix door 9 that can be rotated. An air distribution duct 5 is installed on the lee side of the heater unit 4 and is connected to the cool box 20. Air outlet ports 11 and 12 are provided at predetermined positions of the air distribution duct 5, and opening and closing doors 13 and 14 are attached to each of the air outlet ports 11 and 12 for adjusting the outlet air. Further, ducts 17 and 18 extend from both sides of the box body 21 of the cool box 20, and air outlets 23 and 2
It leads to 4.

However, in the case of such a conventional cool box 20, since the cool box 20 itself is connected to the air distribution duct 5, air conditioning is required to cool the items stored in the cool box 20. Only part of the air blown from device 1 is used. For this reason, when the air conditioner 1 is performing temperature control operations, the temperature of the air flowing into the cool box 20 rises, resulting in a problem that a sufficient cooling effect cannot be obtained. Furthermore, in order to solve the inefficiency of the Cool Box, it is possible to use the Cool Box itself as an electric refrigerator, but this makes it difficult to secure space in the Cool Box and is not economical. This also causes the inconvenience of placing a high burden on the operator (see Japanese Utility Model Application Publication No. 70768/1983).

The present invention was developed by focusing on these conventional problems, and its purpose is to always receive cooling air from the air conditioner, regardless of whether the air conditioner is controlling the temperature. The purpose of the present invention is to solve the above-mentioned conventional problems by providing a cool box of various types.

The gist of the present invention is to integrate a cool box with an air inlet and an air outlet so that cold air is introduced immediately after the evaporator of the air conditioner and is discharged downstream close to the cold air intake. The point is that the valve body is connected through the valve body. The cool box is opened and closed by rotating the lid or the box body, and with this rotating operation, the supply of cold air into the cool box can be turned on or off. With this configuration, the Cool Box is always supplied with cold air that has passed through the evaporator, while this cold air circulates within the Cool Box and returns to the air conditioner to become conditioned air and is blown into the vehicle interior. put out. Therefore, it is possible to increase the cooling efficiency of the cool box and maintain the air conditioning efficiency of the air conditioner.
