Description

[Detailed description of the invention] This invention is a device that encapsulates a cold storage agent and cools a room by the thermal energy absorbed during the phase change of the cold storage agent. Regarding a simple cooling air device.

In recent years, as an alternative to room coolers and air conditioners that have cooling components such as refrigerant compressors and evaporators, a cold storage container filled with a cold storage agent is installed in the machine frame and the phase change of the cold storage agent is utilized. A cooling air device has been proposed that cools the room using air. In such a cold air device, a cold storage agent is filled in a cold storage container made of an aluminum can or a plastic container, and this cold storage container is placed on a box or mesh inside the machine frame, and a blower such as a fan or motor is installed inside the machine frame. Since the device is installed in the machine frame and sucks air into the machine frame for cooling, it has the disadvantage that the device itself is large-scale and difficult to carry and operate. Furthermore, since many parts are installed inside the device, it is difficult to repair or clean the device in the event of a breakdown.

The present invention aims to eliminate the drawbacks of such a cold air device using a cold storage agent, and to provide a cold air device that has a simple structure and is capable of efficient cooling.

The present invention has a machine frame in which an air blowing port and an air absorption port are opened, and a fan that is removably attached to the machine frame and is rotationally driven. The above object is achieved by having a cold storage agent sealed inside the cylindrical body.

Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS. 1 to 4.

FIG. 1 is a perspective view of an embodiment of the present invention, in which an air outlet 3 to which a louver 2 for adjusting the direction and amount of air is attached is opened at the center of the front of a box-shaped machine frame 1, and at the bottom of the front. An air suction port 5 with a wire mesh 4 stretched thereon is opened. In addition, a removable condensation tray 6 is provided at the bottom of the air suction port 5, a lid 7 that can be opened and closed is attached to the top surface of the machine base 1, and a finger for carrying is provided on both sides of the machine base 1. An insertion recess 8 is formed.
Reference numeral 9 is a dial for controlling the rotational speed and turning on/off of the motor installed in the machine base 1, and reference numeral 10 is a lever for changing the direction of the louver 2.

A fan 20 in which a cold storage agent is sealed is removably attached to the machine frame 1 formed in this manner. The main part of the fan 20 is constituted by a hollow cylinder 21 and a plurality of blades 22, 22, attached to the outer surface of the cylinder 21 and formed into an appropriate shape. An end face cover 23, which is closely attached to both left and right end faces of 21 by means of welding, gluing, etc.
24 is attached, and the end covers 23, 2
Rotating shafts 25 and 26 are attached to the center of 4. In this way, the cylindrical body 21 and the end cover 2
A cold storage agent is sealed inside the cylindrical body 21 that is sealed by the tubes 3 and 24. This cold storage agent is made of a substance that can be easily frozen in a household freezer, such as water, saline, paraffin, potassium chloride solution, etc. It is formed by extruding aluminum, for example, so that it does not easily deform due to changes in volume or pressure, and is easy to mold. As shown in FIG. 3, the shaft 2 provided on the end face cover 24 is connected to a shaft coupling 3 supported by a bearing 34 to which rotation is transmitted from a motor 30 via a pulley 31, a belt 32, and a large pulley 32.
3 and one shaft 25 is removably connected to machine frame 1.
The fan 20 is removably supported by a bearing 34' installed within the machine frame 1, so that the fan 20 is rotationally driven within the machine frame 1. Bearing 3
4 and 34' are permanently or temporarily open only in the upper part, and balls, 23, etc. are arranged on the bearing surface,
Alternatively, it may be made of oil-impregnated light-receiving material.

FIG. 4 shows an example of connecting the shaft 26 on the right side to the shaft coupling 33, in which a rectangular shaft rod 27 is attached to the tip of the shaft 26, and this shaft rod 27 has a rectangular shape at the tip of the shaft coupling 33. The shaft 26 and the shaft coupling 33 are engaged and connected by being inserted into the recess 35 and the locking rod 36 being applied from above. The shaft 26 and the shaft joint 33 may not be formed as shown in FIG. 4, but may be connected by, for example, providing a movable sleeve or a friction clutch between the shaft 26 and the shaft joint 33.

According to this embodiment configured as described above, in order to cool the room, the fan 20 is placed in the refrigerator in advance to freeze the cold storage agent in the cylinder body 21.
This fan may be connected to the bearing 34 and the shaft coupling 33 to rotate the motor 30, and as the fan rotates, the air cooled around the fan 20 is discharged from the air outlet 3 and the interior of the room is cooled. Ru. Therefore, according to this embodiment, in addition to the effect of the conventional cold air device using a cold storage container, which eliminates the need for a cooling member, since the cold storage agent is sealed in the cylindrical body of the fan, the cold storage container filled with the cold storage agent can be used. There is no need to prepare a separate container, there is no need for a box or net to place the cold storage container, and there is no need to provide a separate fan, so the device itself can be simplified, made smaller, and requires less maintenance. Easy to clean and assemble. Furthermore, it is easy to change the rotational speed of the motor and replace the coolant, which makes it easy to adjust the temperature.

5A and 5B respectively show another embodiment of the present invention, and FIG. 5A shows a case in which a plurality of fins 28, 28, . , FIG. 3B shows a case in which a plurality of fins 28, 28, . By forming the fan 20 in this way,
The contact area with the cool storage agent sealed inside increases, the heat transfer effect increases, and the cooling efficiency improves. Similarly, the cooling efficiency can also be improved by enclosing a metal wire or a metal piece inside the cylindrical body 21. Further, FIGS. 6A and 6B both show other shapes of the louver 2 attached to the air outlet 3. In the figure A, the sliding sides 2a, 2 slope downwardly toward the machine frame 1.
In the figure (b), a net 2b is stretched over the inner surface of the machine frame 1. By providing these sliding sides 2a and net 2b, water vapor does not condense on the louvers 2, but instead condenses on the sliding sides 2a or the net 2b, so drops do not fall from the louvers 2 to the outside of the machine frame 1, and the room is kept clean. It doesn't get dirty. Furthermore, it is also possible to use a motor with a built-in speed reducer as the motor, which eliminates the need for pulleys and belts and allows the motor to be directly connected to the shaft of the fan, making it more compact. In addition, the present invention can also use a heat storage agent without using a cold storage agent, thereby making it possible to heat the room.

As described above in detail, according to the present invention, it is possible to provide a simple cooling air device that can cool a room with a simple structure and can also adjust the temperature.
