Detailed Description
Hereinafter, the structure of a refrigerator having an intermediate partition for partitioning a refrigerator compartment according to the present invention will be described with reference to the accompanying drawings. In the following description, the intermediate partition is simply referred to as a partition, and is a partition to which a foaming agent is injected for heat preservation.
Fig. 1 shows an installation position of a partition in a refrigerator. In fig. 1, a refrigerator space indicated by reference numeral 10 is, for example, a refrigerating compartment, which is a low-temperature storage compartment maintained at a level for refrigerated preservation without being frozen, and a temperature range thereof is generally set between 1 ℃ and 5 ℃. The refrigerator space indicated by reference numeral 20 is, for example, a temperature-changing compartment, the temperature range of which can be set by the user as desired, for example, to-10 ℃ to 0 ℃, and also to a lower temperature for freezing. The refrigerator space indicated by reference numeral 30 is, for example, a freezing chamber, which is set as a freezing temperature zone. The freezing temperature zone is, for example, -22 ℃ to-18 ℃. However, in order to improve the effect of cryopreservation, the temperature may be set to a low temperature of from-30 ℃ to-25 ℃.
The temperature difference is typically about 10 ℃ between refrigerating room 10 and temperature-changing room 20, and for such a temperature difference, a foaming agent may be injected into the partition between them as necessary, or it is needless to say that the foaming agent may not be injected, and the temperature difference between temperature-changing room 20 and freezing room 30 may be up to 30 ℃.
Fig. 2 is a perspective view showing the internal structure of the separator 100, the separator 100 of fig. 2 is an unencapsulated separator, the central blank portion of which is inner surfaces 101 of the separator 100, and the other opposite inner surfaces are not shown, when a foaming agent is injected into the separator 100, the foaming agent is in contact with and adheres to the inner surfaces 101, although referred to as a separator, since the inside thereof is injected with the foaming agent, it is a hollow flat box before the injection of the foaming agent, and includes two large-area plates, an upper surface plate and a lower surface plate of the thicker separator 100 after being encapsulated, respectively.
As shown in fig. 2, the inner surface 101 of the separator 100 has an area of about 3/4 and is a flat surface, and various parts are mounted on the remaining surface, so that it is uneven and non-flat.
If the foaming conditions vary and the bonding ability of the foaming agent is insufficient, the inner surface of the partition plate is a flat surface with a large area, and therefore the foaming agent may not be firmly bonded to the inner surface of the partition plate and may be detached from the inner surface of the partition plate, and the heat insulating effect of the partition plate may not be secured, resulting in a decrease in the thermal efficiency of the entire refrigerator. The foaming agent is easily detached mainly from the flat portion.
Fig. 3 is a perspective view showing the intermediate partition board to which a plurality of screws 102 are attached according to the present invention, and fig. 4 is an enlarged view showing screws 102 attached to the intermediate partition board, wherein the space exposed in the partition board 100 after the screws 102 are attached is the partition board internal space 106.
In the present invention, the above problem, i.e., the blowing agent is prevented from being detached from the flat portion of the inner surface 101 of the separator 100, is solved by mounting the screw 102 on the inner surface 101 of the separator 100. Since only the screw 102 is installed, the structure is simple and a production mold does not need to be changed.
In order to solve the above problem, the screw 102 needs to have the following two features: (1) the cross section area of the foaming agent in the flowing direction is small, so that the flowing of the foaming agent is not hindered; (2) it has a large screw head capable of fixing the foaming agent in a direction perpendicular to the flow direction of the foaming agent.
The screw 102 of the present invention is described below with respect to the above two features.
The screw of the utility model is composed of a flat screw head and a screw thread part with smaller diameter. As shown in fig. 4, the screw head 103 is an oblate head, and a flange 105 extending horizontally outside the screw head is provided around the oblate head in order to increase the vertical area (the direction perpendicular to the flow direction of the foaming agent when the foaming agent is injected). Since the screw head 103 is flat although having a large area and faces the blowing agent flow, the side surface of the flange 105 and the side surface of the oval head do not interfere with the flow of the blowing agent, and the side surface of the flange 105 and the side surface of the oval head form a streamline shape, contributing to smooth flow of the blowing agent.
Since the threaded portion 104 is small in diameter and preferably circular, it is a cylindrical side surface facing the blowing agent flow like the screw head 103 , and therefore, it does not interfere with the flow of the blowing agent and contributes to smooth flow of the blowing agent.
That is, the screw 102 of the present embodiment has the feature of (1) above.
When the foaming agent is injected, the foaming agent flows above and below the screw head 103 and around the screw part 104 until the screw part exposed to the inside of the partition 100 is entirely surrounded, in the present embodiment, the screw 102 is fixed to the panel body on the side of the partition, so that the foaming agent after foaming is fixed to the panel body on the side of the partition, i.e., the upper or lower panel, via the screw 102, in addition to being directly adhered to the panel body on both sides of the partition, when the foaming agent is not firmly adhered to the panel body and is to be released, the screw head 103 plays a role of lifting (when the foaming agent on the side where the screw 102 is installed is to be released) and/or supporting (when the foaming agent on the side where the screw 102 is not installed is to be released), and the foaming agent can be more firmly fixed because the screw head 103 itself has a large area for lifting and/or supporting.
That is, the screw according to the present embodiment has the feature of (2) above.
The screw 102 of the present invention has a large screw head 103 and a small diameter screw portion 104, and is screwed to the -side plate body of the partition plate 100 as shown in fig. 4.
Although the screw head 103 has the flange 105 for increasing the area of the screw head of the -type screw, in order to increase the strength with which the foaming agent is fixed by the screw head 103, the screw head of the -type screw has a relatively large area, and therefore, the foaming agent can be fixed by the screw, the screw head 103 preferably has a larger screw head area than the screw of -type screw.
Further, not only the strength of fixing the foaming agent can be increased by the screw head 103, but also the strength of fixing the foaming agent can be increased by the screw portion 104. In this case, the screw portion 104 may be exposed to the inside of the separator 100. The foaming agent that has entered between the threads can be tightly fixed to the threaded portion 104.
The screw portion 104 of the screw 102 shown in fig. 4 is a tapping screw having a thin tip, and a boss for screwing the screw is formed on the plate body. However, the screw 102 is not limited to a tapping screw, and may be a screw having a constant diameter of the threaded portion 104. The diameter of the threaded portion 104 is also not particularly limited, but is preferably as small as possible while ensuring the strength of the screw 102 and the stability of mounting. In the state where the screw is screwed into the boss, both the screw head 103 and the screw portion 104 may be exposed inside the partition plate 100, or the screw portion 104 may be completely screwed into the boss and only the screw head 103 may be exposed inside the partition plate 100. In this case, the edge of the screw head 103 exceeds the edge of the boss.
The provision of the bosses ensures the stability of the installation of the screws 102, but the presence of the bosses complicates the structure of the separator 100, increasing the manufacturing cost. In the present invention, the bosses may be omitted and only the upper surface plate and/or the lower surface plate of the partition plate 100 may be provided with screw holes for screwing the screws 102.
The number of screws 102 provided in the present invention is not particularly limited, and may be or more, and screws may be installed at the center of the flat portion of the inner surface 101 of the partition board 100, for example, screws 102 prevent the blowing agent from being detached from the inner surface of the partition board, and the smaller the number of screws is, the smaller the resistance to the flow of the blowing agent is, and the lower the production cost is.
The utility model discloses in, for balanced fixed action and cost etc. can set up a plurality of screws, the distance between each screw is between 100mm to 150 mm. The distance of the screws from the surrounding wall of the interior space of the partition is preferably greater than 100mm, preferably between 100mm and 150mm if the screws are sufficiently large.
The arrangement of the plurality of screws is not particularly limited, and the plurality of screws may be arranged in a square shape, or may be arranged in rows, and adjacent two rows are staggered so that the distance between the screws is 100mm to 150 mm.
Under the condition that the screws are provided as described above, the number of the screws provided varies depending on the size of the area of the inner surface 101 of the partition plate 100. That is, regardless of the area of the partition plate 100, the maximum density of screws may be secured so that the distance between any two screws is 100mm or more.
The upper and lower surface plates (the inner surfaces of which are the inner surfaces 101) of the partition plate 100, including flat parts and non-flat parts on which various components are mounted and provided, and the selection and mounting of screws, on the inner surface 101, wherein the mounting density is the density of all screws on the upper and lower inner surface plates, and the interval between every two screws is 100mm or more.
The refrigerator of the present invention has been described above, but the refrigerator of the present invention is not limited to the above description, and various changes can be made within the spirit of the present invention, and the technical solution obtained after the change is within the scope of the present invention.
