Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an ice-

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates generally to an ice box for temporarily storing foods and the like at a low temperature, and more particularly to an ice box for storing a storage material and a low-temperature solid coolant in an inner space of a housing made of a heat- A liquid separating space capable of separately separating the liquid generated by dissolving the coolant and discharging it to the outside so as to prevent the stored liquid from mixing with the liquid generated in the ice box, Ice box.

Generally, ice boxes are widely used to store fresh food or other items needed for outdoor activities such as outings, camping, fishing, etc. at a low temperature. The ice box generally has an inner space of a casing, such as a rectangular parallelepiped or a cylinder, made of a heat insulating material such as polyurethane or polystyrene foam. The upper portion of the housing is opened and closed by a cover or a lid which can be opened or closed. In the inner space of such a housing, an item such as a food or the like to be stored at a low temperature is put together with a coolant such as ice.

In this way, when a storage material and a coolant of 0 ° C or lower are put together in the inner space of the ice box and left to stand, for example, at about 20 to 30 ° C, the ice as the coolant changes into liquid water . The liquid generated by melting the ice, that is, the water, is mixed with the ice which is not melted yet and the storage material. Therefore, the inside of the ice box becomes dirty and it is inconvenient to take out the wet water storage to the outside of the ice box. And there is a tendency to dissolve relatively quickly so that the cryogenic storage time is shortened. Therefore, although there is an advantage that the coolant called ice can be easily obtained at a relatively low cost in terms of the public, there is a technical demand that the above-mentioned problems should be solved.

In order to meet this demand, an ice pack of a structure containing a solid-liquid phase-changeable coolant in a shell of a dry ice or plastic material which does a solid-gas phase change is used instead of a solid-liquid phase ice as a coolant Is known.

Dry ice, however, is a relatively expensive material and it evaporates rapidly at room temperature, making it difficult to store. Therefore, there is a problem that it is not easy for the general public to obtain, and it is inconvenient and troublesome to use, and there is a limitation in that it is used only for special purposes such as storage of expensive medicinal products.

In the case of ice packs, for example, a refrigerant mixture of water and polymer is placed in a bag-shaped bag made of nylon and PE (polyethylene) or made of plastic in the form of a small box. These ice packs are now widely used for delivering livestock products and aquatic products. However, since the ice pack has a certain shape, there is a problem that the space occupied by the ice pack is relatively large in the space inside the ice box, so that the space for the storage space is greatly reduced. Also, since the water in the refrigerant must be completely dried It was very cumbersome and inconvenient. In addition, when the outer packaging of the ice pack is torn or punctured inside the ice box, there is still a problem that the liquid refrigerant inside the refrigerant flows out and mixes with the storage.

On the other hand, in order to arrange the coolant and the storage in separate spaces, conventionally, for example, in a registration document of Korean Patent Registration No. 10-0797019 (registered on Jan. 16, 2008), the inner space of the ice- Into a space of a predetermined size. According to this technique, the partition member separates the space in the ice box and inserts the coolant and the storage in separate spaces to prevent direct contact between the coolant and the storage. However, according to this prior art, there is a disadvantage that the separating partition member lowers the cooling effect of the coolant. In order to cover this disadvantage, there has been a limitation in that a vent hole through which gas is passed through the partition member is formed, but this is applied only to a coolant in which a cold air flow is implemented as a gas, such as dry ice.

Therefore, there is still a need for a technique for preventing mixing of a liquid and a liquid generated in an ice box, such as a liquid generated by dissolution of a coolant, in an ice box containing a storage and a solid coolant together.

The present invention has been made in order to solve the above problems of the prior art and to provide various additional advantages. In particular, in an ice box for storing a storage material and a low-temperature solid coolant in an inner space of a housing made of a heat insulating material, It is possible to separately separate the liquid generated in the melted state and to separate the liquid from the liquid to be discharged to the outside so as to prevent the stored product from mixing with the liquid generated in the ice box, Box. &Lt; / RTI >

The present invention also provides a water-permeable structure for horizontally dividing the liquid separation space and the remaining storage space at the lowermost part of the ice box into at least the form of a container, a basket, or a pocket, And an object of the present invention is to provide an ice box having a new liquid separation space which can be taken out while being held in a water permeable structure when taking out a stored article stored in the ice box.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

An ice box having a liquid separation space provided in accordance with an aspect of the present invention includes a heat insulation box 10 and a water permeable structure 20, 30, 40, 60, 70, 80, 90.

Herein, the term 'ice box' used in the present specification is only a structure including a wall made of a heat insulating material which houses a storage and a coolant together in an openable and closable inner space. Therefore, a shape of a solid wall (Ice box). In addition, the 'ice box' used in the present invention need not be limited to this. For example, an ice bag made of a flexible material that can be folded and stored when it is not used includes an ice bag Should be interpreted broadly as meaning.

The heat insulating box 10 has a structure similar to that of a conventional ice box, and can include an enclosure 12, a drain hole 14, and a lid 16. The enclosure 12 has a bottom surface and a side wall surface made of a heat insulating material so as to have an inner space. A drain port 14 is provided at the bottom of the bottom surface or sidewall of the housing 12. The upper surface of the enclosure 12 forms an opening, which is also opened and closed by a lid 16 made of a heat insulating material. In addition to these, a handle for allowing the user to hold the ice box by hand or a strap for allowing the user to engage the shoulder can be attached to the outside of the housing 12, and the lid 16 can be closely attached to the housing 12 A means may be formed to urge the user to press down. The heat insulating box 10 having such a structure is substantially similar to a general ice box itself that houses the storage P and the coolant I in its internal space.

The characteristic structure of the present invention is a water permeable structure (20, 30, 40, 60, 70, 80, 90) inserted into the insulating box (10). This water-permeable structure first of all comprises two spaces, that is, an upper storage space 124 and a lower liquid separation space 122, which are adjacent to each other but which are separated from each other by the inner space of the housing 12 of the heat insulating box 10 It is responsible for the physical interface function to divide.

The storage space 124 is a space in which the storage P and the coolant I are disposed. On the other hand, the liquid separation space 122 is a space in which liquid (W) generated by melting the solid coolant (I) such as ice in the storage space (124), that is, water flows down and collects. Even when the liquid component flows down from the storage P stored in the storage space 124, it is collected in the liquid separation space 122 as well.

To this end, various embodiments of the permeable structures 20, 30, 40, 60, 70, 80, 90 commonly have a horizontal interface surface disposed at a constant location in the interior space of the enclosure 12, And interfaces (22, 32, 42, 62, 72, 82, 92). The water permeable interfaces 22, 32, 42, 62, 72, 82, and 92 are configured such that the reservoir P disposed in the storage space 124 and the coolant I in the solid state are separated from the liquid separation space 122, And allows only the liquid to pass therethrough.

1 and 2, the water-permeable interface 22 includes a plurality of through holes 223 through which the liquid passes, and a rigid one And a perforated plate (222). Alternatively, as in the second embodiment illustrated in FIG. 3, the water permeable interface 32 may comprise one or more horizontal support frames 322 and one mesh 323 overlying the support frames 322 . Alternatively, as in the third embodiment illustrated in FIGS. 4 and 5, the permeable interface 42 may be configured as a lower surface of the netting structure that is generally in the shape of a single enclosure or basket. And in an alternative manner, as in the seventh embodiment illustrated in FIG. 9, the water permeable interface 92 may include only the mesh 923 without a horizontal support frame.

The manner in which the water permeable interface 22, 32, 42, 62, 72, 82, 92 is fixedly disposed at a specific position of the housing 12 according to the present invention can be largely divided into three methods, A top attachment method, and a stepped contact method. These schemes may employ one or more than one in various embodiments according to the present invention.

As shown in the first embodiment of Figs. 1 and 2, the second embodiment of Fig. 3, the sixth embodiment of Fig. 8, and the seventh embodiment of Fig. 9, And spacers 23, 33, 83, and 93 for maintaining the height H are employed. These spacers are fixed to the lower surface of the water-permeable interface 22, 32, 82, 92, that is, the surface facing the liquid separation space 122 side. In the illustrated embodiment, the spacers 23, 33, 83, and 93 are each arranged at four corners in the form of a slender vertical column, but the present invention need not be limited to spacers of this type and arrangement. In other words, the shape of the spacer is not limited as long as it can fix the gap H between the lower surface of the water-permeable interface and the bottom surface of the housing 12. It is obvious that the positions where the spacers are disposed are not necessarily arranged at the corners, and can be arranged in various numbers at various positions of the water-permeable interface lower surface, if necessary.

6, at least a part of the edges of the water-permeable interfaces 62 and 72 are formed in the inner space of the housing 12, as shown in the fourth embodiment of Fig. 6 and the fifth embodiment of Fig. 7, And is disposed in contact with the protruding step 120. The step 120 is a protruding shape formed at a position of a height H so as to maintain a gap H with the bottom surface of the housing 12. [ The permeable interface 62, 72 contacts the lower surface of its rim with the step 120 so that its progression from the vertical to the downward direction is stopped, The water permeable interfaces 62 and 72 are caught by the step 120 and do not move downward so that the gap H between the bottom surfaces of the housing 12 is maintained .

The upper attaching method is a method of fixing the water-permeable interface 42 at a position of a height to hold the gap H with the bottom surface of the housing 12, as shown in the third embodiment of Figs. 4 and 5 (51, 52) detachably attached to a predetermined position in the inner space of the housing (12).

Here, the detachment means exemplifies a protrusion-groove structure in the illustrated example. In other words, on the one hand, the engaging projection 51 is formed on the side of the water-permeable structure 40, and on the other hand, the engaging groove 52 is formed at the upper end of the side wall of the housing 12, And can be fitted to the groove 52. The coupling protrusions 51 are formed in the water permeable structure 40 and the coupling grooves 52 are formed in the housing 12. Conversely, in the water permeable structure 40, the coupling grooves 52 And the engaging protrusions 51 are formed on the housing 12. As shown in Fig.

Furthermore, the present invention need not be limited to the detachment means of such protruding-groove structure, but various detachment means are possible. For example, instead of the engaging projections 51 and the engaging grooves 52, a small magnet may be provided at the position so that the magnets are attached to each other. Alternatively, a Velcro structure, also known as a squeak, may be employed.

In addition to the interface function, the second major function of the permeable structure, which is a characteristic structure of the present invention, is that it has a storage space for storing the storage and solid coolant.

In order to form such a storage space, in the first embodiment of Figs. 1 and 2, the second embodiment of Fig. 3, the third embodiment of Figs. 4 and 5, and the seventh embodiment of Figs. 9 to 11, The water permeable structures 20, 30, 40 and 90 form a space for accommodating the storage material and the solid coolant, the upper end of which is open with the water permeable interface 22, 32, 42 and 90 as the bottom surface 36, 46, 96, which are adapted to receive the sidewalls 26, 36, 46, In other words, the water-permeable interface and the side wall portion form one storage space in which the top surface is opened. The storage space and the solid coolant can be stored in this storage space.

According to the present invention, in addition to the permeable interface which is the bottom surface forming the receiving space, the side wall portions 26, 36, 46, 96 may also have a porous structure, preferably a mesh structure. In this embodiment, since the cool air flow can pass through the side wall portions 26, 36, 46, and 96, the plurality of water permeable structures 90 can be separated from the heat insulating box 10 The cooling efficiency is not lowered.

According to the embodiment in which a plurality of the permeable structures 90 are inserted into the enclosure 12, the storage space 124 of a relatively large volume of the enclosure 12 is divided into a plurality of relatively small volume storage spaces The advantage of being able to divide is provided.

It is preferable that the water permeable structure 20, 30, 40, 70, 80 according to the present invention further include at least one hand grip 28, 38, 48, 78, 88, 98 Do. This handle facilitates the operation of removing the permeable structure from the internal space of the enclosure 12 or putting the permeable structure into the enclosure 12, and furthermore, it is preferable that the storage enclosed in the storage space of the permeable structure is provided with the permeable structure, Thereby making it easier to take it out of or insert it into the interior space.

According to the present invention, the material of the components constituting the water-permeable structure may be a flexible material in the form of a mesh structure of a membrane or fabric, a hard material such as a metal mesh or a hard plastic plate, a soft material mixed with a hard material You may. However, since these materials always come into contact with the storage and water, they do not rust, they are not deformed by water and ice, they are good in touch, they do not cause scratches on the surface of the storage due to the scratch, It may be desirable to select a material that will not be present.
