Description

Showcase with rotating shelf "

[0001] The present invention relates to a showcase, and more particularly, to a shelf capable of rotating a disk-shaped shelf inside a housing having an octagonal cross section to maximize the exhibition effect on the article, The present invention relates to a showcase having a typical shelf.

Various types of refrigerator-type showcase for storing the article at a predetermined temperature are used in a place where food or beverage-related articles such as a home, restaurant, or convenience store are handled. Here, the showcase means a showcase where a new article can be displayed to the consumer in order to conveniently display the article, and at least one glass surface is formed so that the article accommodated in the inside is conveniently exposed to the outside.

Such a showcase exposes the inner appearance of the buyer to the buyer, so that it is possible to reduce the unnecessary opening time as well as to visually display the goods stored in the inside, and to arrange the goods inside the refrigerator It is easy to select and identify the article located on the front side, but the article located on the rear side can not be easily selected and identified.

In order to solve the above problems, Japanese Unexamined Patent Application Publication No. 10-1999-012488 discloses an apparatus and a method for disassembling a shelf in which a plurality of disc-shaped shelves are vertically arranged at predetermined intervals in a showcase, A showcase has been proposed and disclosed in which the shelves are rotated to improve the displayability of the shelves with respect to the articles and to facilitate display and selection.

In order to smoothly rotate the disc-shaped shelf in the interior space of the showcase, the conventional showcase as described above must have a cylindrical shape such that the housing or the case interior space of the showcase corresponds to the contour of the shelf, It can be smoothly rotated without interference with the wall surface.

However, in most of the showcases, a plurality of panels or the like are assembled with each other to have a predetermined size and have a rectangular cross section. When the disk-shaped shelf is rotatable as described above, The inner space must be closed with a cylindrical shape, which results in a problem that it takes a lot of cost and time.

Therefore, in order for the inner space to have a cylindrical shape, the panel must be bent in an arc shape instead of a vertical bending, so that the panel is made of a metal material or a glass material having a predetermined thickness, There is a problem that it takes a lot of time and cost to assemble the inner space of the showcase while having a cylindrical shape.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a showcase having a rotatable lathe in which a disc-shaped shelf is rotatably arranged inside a housing having an inner space of an octagonal cross-section to facilitate manufacture and assembly of the showcase housing.

Meanwhile, the object of the present invention is not limited to the above-mentioned objects, and other objects not mentioned can be clearly understood by those skilled in the art from the following description.

According to the present invention, there is provided a portable terminal comprising: a housing including a case having an octagonal cross-section and a door configured to be openable and closable on the front face of the case; A disk-shaped rotatable lathe coupled to the drive shaft vertically formed at the center of the housing space of the case at a predetermined interval and rotated in the housing space upon rotation of the drive shaft; And a drive motor configured to rotate the drive shaft at a predetermined speed, the drive motor being provided in a lower space below the accommodation space of the case.

Here, it is preferable that the case is assembled with the wall structure of the arm surface by fixing the adjoining portions of the panels having the predetermined area to each other.

Also, the rotary type shelf includes: a rotary plate having a circular plate shape in which a plurality of circular ribs and a reinforcing rib are combined and the articles are displayed; A shaft hole formed at the center of the rotary plate and fixed to the drive shaft; And a plurality of partition walls having a predetermined height in a radial direction around the shaft hole and a protruding wall protruding at a predetermined height from the outer circumferential surface of the rotating plate.

Therefore, according to the present invention, since the inner accommodating space of the case has an octagonal cross section, even if the rotary type shelf has a disk shape, it does not have a cylindrical structure through a separate closing member, Thereby saving time and cost.

Further, since the case accommodating space has an octagonal cross section, the panel of the case does not have to be bent in an arc shape, so that it is possible to reduce the time and cost required for assembling and manufacturing the case, It is possible to minimize the gap between the edges of the typical shelf so that the article does not fall downward.

The refrigerator 120 includes a compressor 121 and a condenser 122, And an expansion valve 123 and an evaporator 124 are formed in an upper space of the case 111. [

The drainage water draining means 130 is designed such that the condensate generated on the surface of the evaporator 124 due to the temperature difference between the evaporating pipe temperature of the evaporator 124 and the internal space of the receiving space 124 is condensed, A drainage panel 131 and a drain panel (not shown) are installed to cover the evaporator 124 in the upper space of the case 111 to collect the defrost water W generated from the evaporator 124, And a drain pipe 133 extending from the drain pipe 131 to the lower space through a side wall of the case 111 to discharge the purified water W collected in the drain panel 131 to the water receiving tube 132.

The detergent freezing prevention means 140 is a means for preventing the defrost water W collected in the drain panel 131 from being frozen by the internal temperature of the containing space and the temperature of the evaporator 124, A heat conduction panel 141 having an area corresponding to the area of the drain panel 131 on the inner bottom surface of the drain panel 131 in which the heat conduction panel 141 is collected, And a heat exchange tube 142 having one end connected to the rear end of the condenser tube of the condenser 122 and the other end connected to the front end of the expansion tube 123 of the expansion valve 123.

The drain panel 131 is heat exchanged by the condenser 122 with the refrigerant of the heat exchange tube 142 having a middle temperature of about 40 ° C to 60 ° C to remove the dehydrated water W, So that the problem of freezing of the defrost water W can be prevented.

The refrigerant activating means 150 is a means for activating the molecules of the refrigerant entangled by the heat exchange by causing the refrigerant discharged from the heat exchange tube 142 to flow into the front end portion of the expansion valve 123 at a constant speed and with a constant amount A housing 151 in the form of a tank having a space in which a coolant is reserved inside the housing 151, an inlet 151 for receiving the refrigerant moving from the heat exchange tube 142 toward the inner wall of the housing 151, A tube 152 is formed on the inner wall of the inner space of the housing 151 and the coolant injected toward the inner wall surface of the housing 151 through the inflow pipe 152 is moved to the lower end of the housing 151 while being vortexed or vortex- A spiral guide 153 that moves toward the internal center space of the housing 110 and is phase-changed by the condenser 122 to activate the refrigerant having an unstable state, The refrigerant is discharged from the housing 151 to the upper end of the housing 151 by the internal pressure generated by the refrigerant introduced into the housing 151, A discharge pipe communicating with the end of the pipe 154 and the discharge pipe 154 and corresponding to the discharge end of the housing 151 and discharging the refrigerant discharged from the discharge pipe 154 to the front end of the expansion pipe 123 155).
