Description

[Detailed Description of the Invention] The present invention relates to a container having a structure for supplying gas, such as a cooler case.

Conventionally, for example, in a cooler case installed in a car, the damper that opens and closes the air vent and the damper control lever are mechanically linked, resulting in a complex configuration and a large number of component parts, resulting in frequent failures. The drawback was that the opening/closing operation of the air outlet was complicated.

In addition, a mechanism for adjusting the opening and closing of the air outlet by providing a substantially hemispherical valve body having a rotation axis perpendicular to the air blowing direction in the air outlet is as described in Japanese Utility Model Application Publication No. 57-92544. Although it is already known that
With this configuration, the valve body is susceptible to misalignment due to the blowing pressure, and the required air flow rate may not be maintained. Furthermore, since the valve body is hemispherical, it rotates under its own weight. However, when the valve is left in a half-open state, the degree of opening of the valve fluctuates irregularly due to blowing pressure, vibration, etc., making it difficult to make fine adjustments to the blowing amount.

The present invention eliminates the above drawbacks,
A semicircular air outlet is provided at an appropriate location on the container wall, a circular recess is formed inside the air outlet, and a disk-shaped hole corresponding to the shape of the inner peripheral surface of the recess is formed in the recess. , an unevenness formed between the outer circumferential surface and the inner circumferential surface of the air outlet, the opening/closing switching valve having the air blowing direction of the air outlet as the axis of rotation, and having a partition wall portion that blocks the air outlet and a cutout-shaped opening. The damper and the damper operating lever are mechanically interlocked because the damper and the damper operating lever are connected mechanically. The structure is extremely simple, and even when the valve body is exposed to air blowing pressure, it does not shift its position and the required air flow rate can be maintained. The opening degree of the valve does not fluctuate irregularly, making it possible to finely adjust the air flow rate.Furthermore, the on-off switching valve has a circular recess and a corresponding outer circumferential surface is a complete disk shape, making it possible to rotate the valve. Although it can be made smoothly, the inner circumferential surface of the recessed part and the outer circumferential surface of the on-off switching valve are engaged with each other to ensure a seal between them, thereby preventing clogging and accumulation of fine dust, etc. In addition, the present invention provides a gas supply container such as a cooler case that can eliminate the central axis of the on-off switching valve and eliminate restrictions on the size of its opening.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An automobile-mounted cooler case, which is an embodiment of the present invention, will be described below with reference to the drawings.

1 is a cooler case, 2 is a main body, and 3 is a lid provided on the front of the case. The lid 3 is connected to the main body 2 by a hinge 4 so as to be openable and closable. Reference numeral 5 denotes a semicircular cold air outlet provided at the front part of the bottom of the case, and 6 is a cold air outlet provided at the rear of the case. The cool air supplied from the outlet 5 circulates within the case 1 and is discharged from the case. Beverage cans 7 housed in the container 1 are cooled and exhausted from an air outlet 6. A ventilation duct 8 is connected to the outside of the ventilation port 5, and a ventilation duct 9 is connected to the outside of the ventilation port 6, both of which communicate with a cooler unit (not shown). Further, an on-off switching valve 10 is attached to the air outlet 5 by a configuration described later. Reference numeral 11 denotes a circular recess formed inside the air outlet 5, and a protrusion 12 is formed on the inner peripheral surface of the recess 11. The on-off switching valve 10 has a disc shape corresponding to the shape of the inner peripheral surface of the recessed part 11, and a recessed line 13 that fits with the protruding line 12 of the recessed part 11 is formed on its outer peripheral surface. A knob piece 14 is formed protruding from the center of the on-off switching valve 10, and with the knob piece 14 as a boundary, a semicircular opening 15 corresponding to the shape of the air outlet 5 is formed on one side, and a semicircular opening 15 corresponding to the shape of the air outlet 5 is formed on the other side. serves as a partition wall portion 16 that blocks the air outlet 5. Therefore, the on-off switching valve 10 has a rotation axis in the same direction as the air blowing direction of the air blowing port 5, and is rotatably adjustable. The main body 2 and lid 3 of the cooler case 1 are formed into a hollow double wall structure or other heat insulating structure by blow molding plastic or other molding means.

In the case configured as described above, in order to blow cold air into the cooler case 1, as shown in FIG. Open/close switching valve 1
By pinching the knob 14 of No. 0 and rotating it 180 degrees, the air outlet 5 and the opening 15 are placed in the corresponding position.
It is in an open state and cool air is blown. Also,
As shown in FIG. 2, the knob 1 of the on-off switching valve 10
4 from the position where the ventilation port 5 and the opening 15 correspond.
By rotating by 180 degrees and bringing the ventilation opening 5 and the partition wall portion 16 into corresponding positions, a closed state is established and the blowing of cold air is blocked. Furthermore, by positioning the on-off switching valve 10 between the fully open state and the fully closed state as described above, the amount of cold air blown can be adjusted as desired. Since the on-off switching valve 10 is rotated and adjusted with its axis of rotation in the same direction as the air blowing direction, the on-off switching valve 10 will not be inadvertently misaligned due to the air blowing pressure, and will not move as required. The amount of air blown can be maintained accurately. In addition, since the on-off switching valve 10 does not rotate under its own weight, the degree of opening does not change even when the air blowing pressure or vibration of the automobile occurs, and the desired air blowing amount can be maintained. Allows for fine adjustment of air flow.

In particular, since the opening 15 of the on-off switching valve 16 that engages with the circular recessed portion 11 is in the shape of a cutout, and the on-off switching valve 16 is in the shape of a disc with no notches,
In addition, even when subjected to the pressure of the air flowing through the air outlet 5, it does not tilt within the concave portion 11, and there is no inconvenience that rotation is obstructed unlike with a notch, and rotation operation can always be performed smoothly. can.

The gas supply container according to the present invention can be used not only for the automobile cooler case shown in the above embodiment.
It can be widely used as a variety of containers configured to supply gas, such as a cooler case for leisure use, a thermal insulation case for beverage cans, and a wet towel case.

As is clear from the above description, the present invention provides a semicircular air outlet at an appropriate location on the container wall, forms a circular recess inside the air outlet, and forms a circular recess in the recess. , an on-off switching valve that has a disk shape corresponding to the shape of its inner circumferential surface, has a rotation axis centered on the air blowing direction of the air outlet, and has a partition wall portion that blocks the air outlet and a cutout-shaped opening. The concave and convex strips formed between the inner circumferential surface of the air outlet and the inner peripheral surface of the air outlet are fitted together so that the rotation can be adjusted freely. The structure is extremely simple compared to one in which the damper and damper control lever are mechanically linked, and the valve body does not shift position even when subjected to air pressure, allowing the required amount of air to be maintained. Even when the valve is left in a half-open state, the degree of opening of the valve does not fluctuate irregularly due to blowing pressure, vibration, etc., and the amount of air blowing can be finely adjusted.

Moreover, according to the present invention, the opening of the on-off switching valve is formed in a cutout shape, and there is no notch.
Its outer circumferential surface is in the shape of a complete disk that corresponds to the circular concave portion, allowing for smooth rotational operation, and the inner circumferential surface of the concave portion and the outer circumferential surface of the on-off switching valve are engaged in a convex-concave manner. This makes it possible to ensure the sealing performance between them and prevent clogging and accumulation of fine dust, etc. In addition, by eliminating the central axis of the on-off switching valve, restrictions on the size of the opening can be removed. It produces the effect that can be achieved.
