Description

Freezing showcase for saving power

The present invention relates to a refrigeration showcase, and more particularly, to a power saving type refrigeration showcase configured to reduce energy consumption by intensively supplying cool air only to an area where a refrigeration object is seated in an interior space of a showcase.

Generally, the refrigeration showcase cools the inside of the refrigerator by the phase change due to the evaporation and compression of the refrigerant and the heat exchange therebetween, as in a general refrigerator. The process in which the refrigerant repeatedly performs gasification and liquefaction is called a refrigeration cycle, and the operating principle of the refrigeration showcase is also based on this refrigeration cycle.

The compressor compresses a refrigerant having a large latent heat of evaporation and discharges the refrigerant at a high temperature and a high pressure, and the condenser discharges the heat contained in the high-temperature and high-pressure refrigerant into the atmosphere, thereby bringing it into a high-pressure liquid state. The refrigerant in the high-pressure liquid state is sent to a capillary tube which is dewatered and can control the cooling effect. Then, the refrigerant in the gaseous state expanded while passing through the expansion valve passes through the evaporator in the showcase in a state of low temperature and low pressure. At this time, heat exchange is performed with the air outside the evaporator by the fan (FAN) Warm cold air flows along the cool air flow path to cool the products displayed in the showcase.

On the other hand, the showcase used for storage or display of foods that generally need to be frozen in convenience stores or supermarkets is operated to maintain a low temperature of minus 0 ° C year-round. In the upright vertical stand-up showcase, There is a problem that the operation cost of the cursor is much consumed.

Of course, a showcase having a low internal space, that is, a showcase having a shape in which a door is laid facing upward is advantageous in that the internal space is relatively narrow, so that the operation cost is somewhat reduced. However, such a showcase exhibits a remarkably low product display effect There is a problem.

In addition, since the conventional refrigeration showcase does not generate a large temperature difference in each portion of the internal space, the refrigeration product and the refrigerated product can not be displayed together. Therefore, in order to display both the frozen product and the refrigerated product, it is necessary to provide the refrigeration showcase and the refrigerated showcase, respectively. Particularly, when the quantity of the frozen product and the refrigerated product to be displayed is very small, there is a problem that the cost difficulty as described above becomes greater.

In addition, the general refrigeration showcase is made of glass walls on the front and side so that the products displayed on the inside can be seen from the outside. Because of the frequent occurrence of condensation on the glass wall due to the difference in temperature between inside and outside, There is a problem that a limit is raised in height.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of a refrigeration showcase according to the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is a perspective view of a refrigeration showcase according to the present invention, Fig. 2 is an exploded perspective view of the refrigeration showcase according to the present invention, Fig. 3 is a front view of the refrigeration showcase according to the present invention, Fig.

The refrigeration showcase according to the present invention is constructed in a structure erected upright so as to increase the shelf effect, that is, the structure having a very wide internal space. However, the refrigerant is concentrated only in the space where the frozen products are displayed, So that it is constituted.

In order to achieve the above-described effects, the refrigeration showcase according to the present invention includes a body 100 having various devices for power supply and refrigerant compression, and an outer glass wall (not shown) surrounding the upper space of the body 100 A freezer bottom plate 300 positioned on the upper surface of the body 100 and having an inlet port 310 formed in front of the freezer bottom plate 300 and a freezer bottom plate 300 surrounding the front side and the left and right sides of the freezer bottom plate 300, A freezing glass wall 320 provided with a space 330 for guiding the air introduced into the air inlet 310 to a rear upper side of the freezer bottom plate 300 through a lower side of the freezer bottom plate 300, A freezing chamber 500 and an evaporator 600 mounted in the freezer compartment 400 and a freezer compartment 500 spaced upward from a discharge end of the freezer compartment 400 and having a bottom surface connected to the freezer glass wall 320, And is discharged from the cool air passage 400 A guide plate 700 extending upward and formed in a forwardly bent shape and mounted on a discharge end of the cold air flow path 400, . A rear door 210 is provided on the rear side of the outer glass wall 200 for pulling in and out the display products.

The evaporator 600 is a component that generates cold air by absorbing the surrounding heat as much as the latent heat of evaporation generated during the phase change of the refrigerant compressed at a high temperature and a low pressure to the gas, A detailed description of the evaporator 600 will be omitted.

The cooling air flow path 400 includes a flow path wall 420 rising upward from the rear end of the freezer bottom plate 300. The air drawn into the inlet port 310 by the flow fan 500 flows through the flow path wall 420 and moves to the front side of the refrigerated product display space 330 after hitting the ceiling plate 410.

The cold air discharged into the refrigerated product display space 330 is heated to a certain level while cooling the refrigerated products displayed on the freezer floor plate 300. The air heated to a certain level is further returned through the inlet port 310 to the evaporator 600 To cool down. That is, in the cooling showcase according to the present invention, the air cooled by the evaporator 600 is recirculated so as to pass through only the refrigerated product display space 330 and the cooling channel as shown by an arrow in FIG. 4, And the energy consumption can be minimized.

It is preferable that the flow fan 500 is disposed near the inlet port 310 of the cool airflow channel 400 so that cool air in the refrigerated product display space 330 can flow more smoothly toward the inlet port 310, The evaporator 600 may be installed on a side close to the discharge end of the refrigerant flow path 400 so that the cold air supplied to the inside of the refrigerated product display space 330 can be supplied in the coldest state.

Even if the air cooled by the evaporator 600 is circulated only in the refrigerated product display space 330 as described above, even if the inner space is surrounded by the outer glass wall 200, Will not remain cold enough to store the frozen product. That is, the refrigerated product display space 330 in which cold air is continuously circulated remains in a sub-zero state, but the upper side of the refrigerated product display space 330 does not maintain a sub-zero state.

Of course, some of the cool air discharged to the outlet side of the cold air flow path 400 is transmitted to the upper side out of the refrigerated product display space 330, so that even inside the outer side of the freezing product display space 330, The outer glass wall 200 is kept cooler than the outside. Therefore, the refrigeration showcase according to the present invention utilizes the area outside the refrigerated product display space 330 (the upper area of the frozen product display space 330 in this embodiment) as the refrigerated product display space in the inner space of the outer glass wall 200 . That is, a shelf 800 capable of placing a refrigerated product can be further provided at a point spaced upward from the upper end of the freezer glass wall 320.

If the shelf 800 is further provided on the upper side of the refrigerated product display space 330, the user can store both the frozen product and the refrigerated product, thereby eliminating the need to purchase a separate refrigerated showcase for storing the refrigerated product Effect can be obtained. Although only one shelf 800 is shown in this embodiment, more than two shelves 800 may be installed.

The shelf 800 may be provided with a lighting unit 900 for illuminating the frozen product displayed on the freezer bottom plate 300 and may be provided on the ceiling of the outer glass wall 200, And a lighting unit 900 for illuminating the refrigerated product. It is preferable that the lighting unit 900 is made of an LED having little heat generation so as not to raise the internal temperature of the refrigeration showcase according to the present invention.

The temperature difference between the inside and the outside of the outer glass wall 200 is significantly increased and the temperature difference between the inside and the outside of the freezer glass wall 320 is also largely generated, so that the outside glass wall 200 and the freezer glass wall 320 ) May cause a condensation phenomenon. When the condensation occurs, the frozen product displayed on the freezer bottom plate 300 or the refrigerated product displayed on the shelf 800 is not clearly exposed to the outside, so that the effect of displaying the product is significantly reduced .

Accordingly, the outer glass wall 200 and the freezer glass wall 320 may be configured to generate heat by external power applied thereto, so that no condensation may occur. The outer glass wall 200 and the freezer glass wall 320 have a positive terminal and a negative terminal, respectively, because the outer glass wall 200 and the freezer glass wall 320 are connected to each other with hot wires. It is preferable to be made of a conductive glass.

Since the conductive glass is commercially available in various devices for preventing condensation, a detailed description of the internal structure and operating principle of the conductive glass is omitted.

Fig. 5 is an enlarged sectional view showing a mounting position of the guide plate 700 included in the present invention, and Fig. 6 is an enlarged sectional view showing a cold discharge direction of the refrigeration showcase according to the present invention.

The guide plate 700 installed on the outlet side of the cold air flow path 400 (in this embodiment, the upper side of the evaporator 600) is configured to allow the cold air discharged upward through the evaporator 600 to flow upward in the refrigerant product display space 330 (Two in the present embodiment) as shown in the present embodiment so as to more effectively convert the flow direction of the cold air passing through the evaporator 600. As shown in FIG. That is, the guide plate 700 may include a first guide plate 710 and a second guide plate 720, and the first guide plate 710 may be upwardly moved from a position located behind the flow path wall 420 And a first transverse plate 714 extending forward from an upper end of the first transverse plate 712. The second transverse plate 720 is composed of a first transverse plate 720, And a second transverse plate 724 extending forward from the upper end of the second transverse plate 722. The second transverse plate 722 extends upward from the upper end of the second transverse plate 712 and the channel wall 420. [

When a first guide plate 710 and a second guide plate 720 are provided on the upper side of the evaporator 600 as described above, a part of the cool air discharged through the evaporator 600 is guided by the first guide plate 710 The second guide plate 720 moves forward and the effect of guiding the flow direction of the cool air toward the front side of the freezing product display space 330 is remarkably increased.

When the cold air flowing in front of the freezing product display space 330 by the first transverse plate 714 and the second transverse plate 724 collides at right angles with the freezer glass wall 320, The flow direction of the cold air impinging on the freezing glass wall 320 may be changed into a downward direction and flow into the inlet 310. However, There is a problem that the amount of energy used for storing the frozen product is increased because the refrigerant flows out of the display space 330.

Therefore, the freezing showcase according to the present invention is configured such that the cold air that has flowed forward in the freezing product display space 330 by the first transverse plate 714 and the second transverse plate 724 collides with the freezer glass wall 320 at right angles So that most of the cold air impinging on the freezer glass wall 320 flows into the inlet 310. In other words, the first transverse plate 714 and the second transverse plate 724 are inclined in a decreasing direction toward the front, that is, as shown in FIG. 5, the first transverse plate 714 and the second transverse plate 724 Is arranged to be inclined downward by an angle of '?' With respect to the horizontal line.

As described above, when most of the cold air that has flowed to the front side of the refrigerated product display space 330 flows into the air inlet 310, the temperature in the refrigerated product display space 330 can be kept sufficiently low even if the driving rate of the evaporator 600 is lowered , And energy consumption can be reduced. If the inclination? Of the first transverse plate 714 and the second transverse plate 724 is set excessively large, the refrigerant discharged through the first guide plate 710 and the second guide plate 720, So that the freezing product display space 330 can not be uniformly cooled as a whole. Therefore, the inclination? Of the first transverse plate 714 and the second transverse plate 724 should be appropriately set according to various conditions such as the specification of the refrigerated product display space 330 and the discharge pressure of the chilled air.

Meanwhile, the first guide plate 710 and the second guide plate 720 form an air curtain on the upper side of the refrigerated product display space 330 to more effectively protect the cold air in the refrigerated product display space 330 Or < / RTI > That is, the distance between the first vertical plate 712 and the second vertical plate 722 is set to be larger than the distance between the first horizontal plate 714 and the second horizontal plate 724 desirable.

When the distance between the first vertical plate 712 and the second vertical plate 722 is set to be larger than the distance between the first horizontal plate 714 and the second horizontal plate 724, The cold air introduced into the space between the first vertical plate 712 and the second vertical plate 722 is accelerated and discharged through the space between the first horizontal plate 714 and the second horizontal plate 724, The effect of forming the curtain can be obtained. When the air curtain is formed on the upper side of the refrigerated product display space 330, the cool air in the refrigerated product display space 330 can be more surely prevented from flowing upward, thereby further improving energy saving efficiency.

At this time, as the amount of cool air used for forming the air curtain increases, the amount of cool air used to cool the frozen product displayed on the freezer bottom plate 300 decreases, and thus the case where the frozen product can not be normally cooled Lt; / RTI >

Therefore, the refrigeration showcase according to the present invention is designed so that the amount of cool air used to form the air curtain (the amount of cool air discharged between the first transverse plate 714 and the second transverse plate 724) cools the frozen product The vertical distance between the first transverse plate 714 and the second transverse plate 724 is set to be smaller than the amount of cool air used (the amount of cool air discharged between the upper end of the flow path wall 420 and the second transverse plate 724) The directional spacing distance is preferably set to be narrower than the vertical distance between the upper end of the flow path wall 420 and the second lateral plate 724.

While the present invention has been described in detail with reference to the preferred embodiments thereof, the scope of the present invention is not limited to the specific embodiments, but should be construed in accordance with the appended claims. Those skilled in the art will appreciate that many modifications and variations are possible without departing from the scope of the present invention.
