The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. It is provided to let you know. Therefore, the embodiments described in the present specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and are not intended to represent all of the technical ideas of the present invention. Therefore, various equivalents It should be understood that water and variations may be present.

FIG. 1 is a plan view showing a structure of a refrigerated container capable of simultaneously carrying fresh cargoes having different storage temperatures according to an embodiment of the present invention. FIG. 1 (a) Respectively.

As shown in Figs. 1 (a) and 1 (b), a container main body 100 constituting a space in which cargo can be loaded and a plurality of compartments in the container main body 100 in accordance with the storage temperature of the cargo At least two or more sensor modules 300 capable of monitoring the condition of each of the separated compartments, at least two sensor modules 300, And a cooling module 400 for supplying cool air of different temperatures to the compartments. In addition, a cool air shutoff unit 500 is further provided to move the cool air supplied from the cooling module 400 to the periphery of the container door to form an air curtain with the moved cool air when the container door is opened.

The compartment module 200 includes a shielding plate 210 formed of a panel plate for shielding the separated compartments and the compartments from each other, and a groove for removing the shielding film 210, At least two supporting portions 220 are detachably connected to each other between the partition walls and the partition walls through a magnetic force or connection means (coupling rings), and a supporting portion 220 for supporting the shielding film 210, (240) which is fixed to an end of the supporter (220) to block the passage of cold air to block the mixing of cool air between the separate compartments, And a compartment opening / closing controller 250 for controlling opening and closing of the compartments separated on the basis of a result of comparison between the separated compartment internal temperature measured by the sensor unit 300 and a predetermined set temperature.

At this time, the supporting part 220 may be configured as a moving rail so that the supporting part 220 can move forward and backward in a state in which the supporting part 220 is closely contacted with the partition wall in a parallel direction. Accordingly, the size of the compartment inside the refrigerated container can be adjusted according to the amount of various fresh crops. For reference, the moving rail is composed of beads, wheels and slide type rails which are conventionally used, and various embodiments are possible.

In accordance with the number of the support parts 220 connected through the hinge part 230, it is possible to divide the inside of the refrigerator container into two or three.

The reason for controlling the opening and closing of the compartments separated through the compartment opening / closing control unit 250 is that when the separated compartment internal temperature becomes higher or lower than the set temperature due to the influence of the inside or the outside, The driving of the module 400 may be enhanced, but adjusting the driving of the cooling module 400 every time causes waste of electric power. Therefore, in order to minimize the waste of such power, the internal temperature of the compartment can be adjusted through contact with another compartment having a lower storage temperature than the compartment.

Accordingly, the direction of the cold air flow between the separated compartments can be shifted to six kinds of cold air flow as shown in FIG. 2, and the compartment opening / closing control unit 250 is controlled in the following two ways.

The first is a method for controlling the opening / closing of the compartments selectively opened and separated among the supporting portions 220 detachably connected to each other through the hinge portion 230. The second is a method for controlling the opening / closing of the 6-way valve ) To open and close the cold air passage between the compartments so as to control the flow of cold air between the separated compartments.

The sensor unit 300 includes a temperature and humidity sensor, and senses the internal temperature or humidity of the separated compartment and transmits the detected temperature or humidity to the compartment opening / closing controller 250.

The cooling module 400 includes coolers 400a, 400b, 400c, and 400c for generating cool air to generate cool air through the fan, and a passage for transmitting cool air generated from the cooler to at least one of the separated compartments And air passage portions 410a, 410b, and 410c.

At this time, the coolers 400a, 400b and 400c are positioned at the innermost side of the container body 100. [ Therefore, the separated compartments located outside the container body 100 (the container door) necessarily include air passages 410a and 410c for moving the cool air from the interior of the container body 100 to the compartment, The separated compartment located at the innermost side of the compartment 100 may be directly transferred into the compartment without a separate air passage portion 410b for transferring the cold air from the cooler 400b.

In the case of the cooler 400b not including the air passage part 410b, the position of the cooler 400b or the direction in which the cool air is emitted can be selectively adjusted from the upper part to the lower part of the compartment, . This can effectively control the cool air transferred to the fresh cargo by adjusting the position where the cool air is discharged according to the quantity or type of the fresh cargo stored in the compartment to the upper / middle / lower part.

The open / close sensing unit 501 senses whether the container door is opened or closed. When the container door is detected to be opened through the opening / closing sensing unit 501, And a cold air discharge unit 502 for blocking the discharge of the cold air when the door is detected as being closed.

As shown in the plan view of FIG. 3A and the sectional view of FIG. 3B, the bottom surface of the container body 100 has a plurality of bars (not shown) An air lift portion 700 is disposed between the frame 600 and the frame 600 to form an arched curve symmetrical with respect to the upper portion to raise the cool air flow in the lower portion of the container upward, .

At this time, the air lifting unit 700 is not limited to the arcuate curved lines having symmetrical structures on both sides, and the arcuate curve may be formed only on one side.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It will be apparent to those skilled in the art that various modifications may be made without departing from the scope of the present invention. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
