The present invention relates to a winding structure of the evaporator winding for the front opening and closing storage chamber of the kimchi storage, and more specifically, in the kimchi storage is formed in the storage chamber is opened in the longitudinal direction in the longitudinal direction from one side inside the main body, the wiring in the rear of the front opening and closing storage compartment By wiring the wiring structure of the evaporator to be in an optimal state, it is possible to minimize the temperature deviation inside the storage compartment and to prevent the refrigerant from flowing into the compressor in the liquid refrigerant state as the evaporation of the refrigerant is satisfactorily implemented. The present invention relates to a winding structure of an evaporator for a front-opening storage room of a kimchi storage room to improve thermal efficiency.

As is well known, Kimchi Storage is a home appliance that has a ripening heater that can ripen kimchi, a cooling system that performs cooling to keep kimchi fresh for a long time at low temperature, and a temperature control system that can control the proper storage temperature. Product.

In this way, the Kimchi storage can be stored fresh for a long time by using a cooling system in the kimchi container in the Kimchi container, as well as appropriately aged kimchi through the aging heater according to the user's preference, then the appropriate temperature It is configured to keep the flavor of ripe kimchi at low temperature for a long time.

Therefore, the kimchi storage is a home appliance that can maintain the taste of kimchi and the freshness of kimchi for a long time regardless of the change of season.

Therefore, the use of kimchi storage is gradually increasing as the housewife has recently been spotlighted in the long-term storage of kimchi at home.

Such a kimchi storage can be divided into a top-opening type that the door is hinged attached to the upper surface of the storage compartment according to the door opening and closing method, a drawer type of the door is a drawer form, and a combination of the top open and drawer type.

Here, an example of a composite kimchi storage having an upper opening / closing storage compartment and a drawer storage compartment among various kimchi storages classified according to the door opening and closing method as described above will be described.

That is, as shown in FIGS. 1 and 2, a plurality of upper open / close storage chambers 200 are usually partitioned above the main body 100 of the kimchi storage, which forms an appearance, and the plurality of upper open / close storage chambers 200 are defined. Hinge is coupled to the top of the back of the main body 100 to open and close the two upper doors 300 to open and close.

In addition to the plurality of upper opening / closing storage chambers 200 which are opened and closed by the upper door 300 as described above, a drawer storage chamber 500 which is opened and closed by a drawer door 520 moved to the front of the machine room 400 is provided. have.

Here, the drawer-type storage compartment 500 is provided with a detachable shelf 530 for receiving and storing a separate kimchi container containing vegetables or kimchi, and the shelf 530 is a drawer-type door 510. It is intended to be seated on a guide rail (not shown) fixed to it.

In addition, a machine room 400 in which a compressor 410 and a condenser (not shown), etc., for a cooling cycle are disposed below the upper opening / closing storage chamber 200 is separately partitioned.

Evaporators 420 and 430 for supplying cold air are wrapped around the incases 210 and 510 constituting the upper opening / closing storage chamber 200 and the drawer storage chamber 500, respectively, and are arranged at regular intervals, and the evaporators 420 and 430 are The refrigerant is circulated through the compressor 410 and the condenser (not shown) of the machine room 400, respectively.

At this time, the evaporator 420 wound around the incase 210 constituting the upper opening / closing storage chamber 200 has a tube-shaped refrigerant pipe (or evaporation tube) through which the refrigerant flows, at regular intervals on the outer circumferential surface of the incase 210. The evaporator 430 installed at the outer side of the incase 510 constituting the drawer type storage chamber 500 is disposed in the form of a depression across the back and side of the incase 510. In most cases.

In particular, in the case of the drawer storage compartment 500 as described above, in order to make up for the drawbacks of the cold air transfer and cooling heat transfer efficiency of the drawer storage compartment 500 in a fast time, the material of the incase 510 itself has good thermal conductivity Injecting the material, or as a way to ensure the maximum contact area between the evaporator 430 and the incase 510, the bracket 600 made of aluminum sheet of a high heat conductive heat evaporator 430 and the case ( Various methods, such as intermediation between 510, are being devised.

On the other hand, recently, the kimchi storage with a separate wine storage room for storing the wine while having a front-open door that opens and closes in addition to the drawer-type storage room 500 that is opened and closed by a drawer type with various functions added to the kimchi storage. It is becoming.

In other words, due to the recent trends and personal preferences such as Lifestyles Of Health And Sustainability (LOHAS) or Well-being, more and more people are looking for wine. How to use the wine is being explored.

In the case of a storage compartment having a front open / close door such as a wine storage compartment, the incase constituting the wine storage compartment has a shape in which the front is opened, and thus the evaporator 420 in the incase 210 constituting the upper opening / closing storage chamber 200. Evaporator must be installed in a new way different from the

That is, the evaporator 430 having a recess shape is installed on the back and side surfaces of the incase 510 in the same manner as the evaporator 430 installed in the incase 510 constituting the drawer storage compartment 500. will be.

Particularly, in the case of the wine cellar, unlike a conventional kimchi cellar, the wine cellar is stored and stored so that the wine cellar is formed long in the vertical direction so that the wine bottles can be laid down one by one and stored sequentially in the upper and lower ends. Will be.

By the way, when the wine cellar is formed long in the vertical direction on the main body of the kimchi storage in this way, as shown in Figure 3, when wiring the evaporator 700 installed in the wine cellar 600, the general of the conventional evaporator Similar to the wiring structure, the refrigerant pipe 710 may be sequentially wound from the lower side to the upper side of the wine cellar 600.

Accordingly, the refrigerant inlet 711 of the evaporator 700 is provided at the lower side of the wine cellar 600, and the refrigerant outlet 712 of the evaporator 700 is formed at the upper side of the wine cellar 600, whereby the refrigerant is wine. It takes a wiring structure to move from the bottom of the storage compartment 600 to the top.

However, in this case, as the temperature distribution of the lower portion of the storage compartment in the wine cellar 600 is relatively lower than that of the upper portion, the natural convection is not well achieved, and thus the temperature difference between the upper and lower portions of the wine cellar 600 is lower. There was a problem that occurred a lot.

And, as shown in Figure 4, for example, while having a structure in which the refrigerant pipe 710 wound in the wine cellar 600 is sequentially wound from the upper side to the bottom of the wine cellar 600, the wine cellar When the refrigerant inlet 711 of the evaporator 700 is provided at the upper side of the 600, and the refrigerant outlet 712 of the evaporator 700 is formed at the lower side of the wine cellar 600, the inside of the evaporator 700 is formed. As the flowing refrigerant flows rapidly from the upper portion to the lower portion of the wine cellar 600, the refrigerant flows quickly due to its own weight, and thus, there is a high possibility that the refrigerant may be introduced into the compressor (not shown) as a liquid refrigerant, as the refrigerant does not completely evaporate. There is a problem that the thermal efficiency is lowered.

Accordingly, the present invention has been invented to solve the above problems, the object of the present invention is a kimchi storage in which the front open and close storage compartment is formed long in the vertical direction from one side inside the main body, the wiring in the rear of the front open and close storage compartment By wiring the wiring structure of the evaporator to be in an optimal state, it is possible to minimize the temperature deviation inside the storage compartment and to prevent the refrigerant from flowing into the compressor in the liquid refrigerant state as the evaporation of the refrigerant is satisfactorily implemented. It is to provide an evaporator winding structure for the front open and close storage room of Kimchi storage to improve the thermal efficiency.

In order to achieve the above object, the present invention provides a kimchi storage in which the evaporator is wound on the outer circumferential surface of the incase in a kimchi storage having a storage compartment composed of an incase which is opened and closed with one refrigerant pipe having a refrigerant inlet and a refrigerant outlet. The refrigerant pipe constituting the evaporator comprises a refrigerant pipe of the upper section which is wound around the outer circumferential surface of the incase while the refrigerant pipe includes the refrigerant inlet, and the refrigerant pipe of the upper section and the refrigerant pipe of the upper section. Refrigerant pipes of the lower section which is disposed on the lower side of the outer peripheral surface of the incase is divided into two sections continuous to each other; the refrigerant pipe of the upper section including the refrigerant inlet is the refrigerant upwards toward the upper portion of the incase relative to the refrigerant inlet Is wound up in a zigzag fashion so that the top The coolant tube extending from the coolant tube side toward the lowest end of the lower section and extending toward the lower end of the lower section is wound up in a zigzag fashion so that the coolant flows upward again, and immediately after the coolant pipe in which the coolant inlet of the upper section is formed. It is achieved by providing an evaporator winding structure for the front opening and closing storage chamber of the kimchi storage, characterized in that arranged at a lower interval and the refrigerant outlet is located.

Here, the winding ratio of the refrigerant pipe of the upper section and the refrigerant pipe of the lower section is preferably disposed in the length ratio of 1: 2.

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

In this case, the present invention may be applied to all kimchi storage having a front opening and closing storage compartment with an open front surface, the incase constituting the storage compartment is formed long in the vertical direction, in the description of a preferred embodiment of the present invention The kimchi cellar having this open wine cellar will be described by way of example.

As shown in the figure, the kimchi storage having a wine cellar according to an embodiment of the present invention, the storage compartment 20 and the machine room 60 is formed therein, and the storage compartment 20 It has a wine storage room 40 having an upper opening and closing door 30 for opening and closing, and a front opening and closing door 50 that can be opened and closed by the front of the body 10 in one side empty space of the storage compartment 20.

In the machine chamber 60 formed in the lower region of the main body 10, a compressor 61 for compressing a refrigerant at high temperature and high pressure, a condenser 62 for condensing the compressed refrigerant in a liquid phase, and the like are provided. And the evaporators 63 and 64 arranged to supply cold air to the wine cellar 40.

That is, evaporators 63 and 64 made of a refrigerant tube (or an evaporation tube) through which refrigerant may flow are installed on the outer circumferential surfaces of the incases 21 and 41 constituting the storage compartment 20 and the wine compartment 40, respectively. It will be.

As such, since the evaporators 63 and 64 are integrally mounted and contacted with the outer circumferential surfaces of the incases 21 and 41, cold air may be supplied into the storage compartment 20 so that kimchi can be stored for a long time. In the wine cellar 40 will be able to store the wine at an appropriate temperature.

Here, the incase constituting the storage compartment 20 and the wine compartment 40 is manufactured to have an empty box shape inside.

In particular, the incase 41 constituting the wine cellar 40 is formed as a single storage space that is opened by the injection.

Therefore, the wine storage chamber 40 has a structure that can store the wine as the front portion of the main body 10 is opened and closed by the front openable door 50, preferably the wine bottle 70 in the height direction The wine cellar 50 is configured to keep lying down.

As such, in the case of the wine storage room 40 to which the present invention is applied, the wine storage room 40 itself is placed on one side of the main body 10 so that the wine bottles 70 can be laid one by one and stored sequentially over the top and bottom. It has a structure formed long in the direction.

In this case, a plurality of wine racks 80 are installed along the height direction of the wine storage room 40 so that the wine bottles 70 may be individually stored in the wine storage room 40, and the wine rack 80 is wine It is preferable that the slide rails are formed on both sides of the storage chamber 40 so as to slide in and out to the front side.

Here, the present invention relates to how to arrange and mount an evaporator 64 installed to supply cold air into the wine cellar 40 in the kimchi cellar having the wine cellar 40 configured as described above.

That is, the present invention, when the wine storage chamber 40 is formed long in the vertical direction in consideration of the storage characteristics of the wine bottle 70, when the winding arrangement of the evaporator 64 in the manner as described in the prior art Since there is a problem such as a large temperature deviation occurs in the upper and lower inside the storage compartment 40, it is characterized by having an optimal evaporator arrangement structure that can be improved by reducing the temperature deviation.

To this end, the present invention provides a wiring structure of the evaporator through one preferred embodiment as shown in Figs.

That is, FIG. 7 is a perspective view showing a form in which an evaporator is mounted in an incase constituting a wine cell according to a preferred embodiment of the present invention, and FIG. 8 is a refrigerant tube constituting the evaporator according to the present invention bent in a zigzag form. 9 is a perspective view showing an arrangement state, Figure 9 is a perspective view showing the step of bonding the refrigerant pipe of the evaporator according to the present invention, Figure 10 is a perspective view showing a bracket bending step of the mounting method of the evaporator according to the present invention, Figure 11 is A perspective view showing an evaporator mounting step of the mounting method of the evaporator according to the present invention.

As shown, the wiring structure of the evaporator according to the present invention, the length of the total refrigerant pipe 65 constituting the evaporator 64 disposed in the incase 41 of the wine storage chamber 40 is continuous with each other When arbitrarily divided into sections, the refrigerant pipe 65 of the upper section (h) including the refrigerant inlet (68) and the refrigerant pipe (65) of the lower section (H) including the refrigerant outlet (69) In this case, the refrigerant pipe 65 of the upper section h is wound around the upper side of the wine storage chamber 40, and the refrigerant pipe 65 of the lower section H is the refrigerant of the upper section h. Compared to the tube 65 has a structure that is wound on the lower side of the wine cellar 40.

Here, the refrigerant pipe 65 of the upper section (h) including the refrigerant inlet 68 is wound upwardly in a zigzag form so that the refrigerant flows upward toward the upper portion of the wine storage chamber 40 based on the refrigerant inlet 68. Then, the winding is vertically extended toward the lower end of the lower section (H) at the upper end of the refrigerant pipe (65) of the upper section (h).

At this time, the refrigerant pipe 65 extending vertically from the uppermost end of the upper section (h) toward the lowermost end of the lower section (H) is wrapped away from the lateral end portion of the refrigerant pipe 65 wound in a zigzag at a predetermined interval. Is wound into.

Then, the refrigerant pipe 65 extending toward the lower end of the lower section (H) by the vertically extending refrigerant pipe 65 as described above is again wound up in a zigzag form so that the refrigerant flows upward, and then optionally The lower end of the coolant pipe 65 of the upper section (h) that is divided, that is, the coolant inlet 68 is provided with a predetermined interval immediately below the coolant pipe 65 formed with the winding outlet 69 is located .

On the other hand, the present invention is characterized in that the winding ratio of the refrigerant pipe 65 of the upper section (h) and the refrigerant pipe (65) of the lower section (H) is wound at a length ratio of 1: 2.

The determination of the winding ratio of the refrigerant pipe 65 of the upper section (h) and the refrigerant pipe (65) of the lower section (H) occurs in the wine cell chamber 40 through repeated experiments by trial and error method. This is due to the results of empirically verifying that the temperature deviation is improved in the process of finding the most effective winding structure in improving the problem of temperature deviation.

In particular, in the winding one continuous continuous refrigerant pipe 65 as the refrigerant pipe 65 of the upper section (h) and the refrigerant pipe 65 of the lower section (H) as described above, in each winding section When the refrigerant pipe 65 is wound so that the refrigerant flows downward along the storage chamber by winding the refrigerant upward, the refrigerant flows completely at the refrigerant outlet 69 side of the evaporator as the refrigerant flows rapidly under the influence of its own weight. As the evaporation does not occur, it is possible to compensate for the problem of the liquid refrigerant flowing into the compressor.

That is, in the case of the refrigerant flowing in the evaporator according to the present invention, the flow of the refrigerant is less influenced by the self-weight of the refrigerant because it flows upward in most of the section, this is due to the sufficient heat exchange during the refrigerant flow evaporation This can be enough to improve the problem of entering the compressor in the state of the liquid refrigerant.

On the other hand, with reference to the accompanying drawings, a preferred manufacturing process and mounting process of the evaporator is configured by winding one refrigerant pipe according to the present invention in more detail as follows.

As shown in FIGS. 8 to 11, the manufacturing process and the mounting process of the evaporator 64 according to the present invention are divided into the refrigerant pipe preparation step → refrigerant pipe bonding step → bracket bending step → evaporator mounting step. can see.

First, the refrigerant pipe preparation step, as shown in Figure 8, as a preparatory step of arranging in the form of an evaporator 64 that requires a refrigerant pipe 65 that constitutes the evaporator 64, a refrigeration system As described above, the entire refrigerant pipe 65 constituting the evaporator includes a refrigerant pipe 65 and a refrigerant outlet 69 of the upper section h including the refrigerant inlet 68. The lower section (H) to be arbitrarily divided by the refrigerant pipe (65) is a step of manufacturing by bending a plurality of times in a zigzag form in each section of the ratio 1: 2.

When the refrigerant pipe 65 is prepared for manufacturing, the refrigerant pipe bonding step is performed. That is, as shown in Figure 9, the refrigerant pipe bonding step, by bonding the refrigerant pipe 65 manufactured in the form of evaporator 64 to the bracket 66 made of aluminum sheet, Placing the bonded vinyl 67 on the bracket 66 made of, and put the coolant pipe 65 prepared in the coolant pipe preparation step thereon, and then heat the bonded vinyl (67) while melting the coolant pipe (65) ) And the bracket 66 made of an aluminum sheet is bonded.

By bonding the bracket 66 and the coolant tube 65 through the joining vinyl 67 that melts by heating in this manner, the adhesion is greatly improved as all the parts of the coolant tube 65 are evenly bonded on the bracket 66. do.

At this time, the bonding vinyl 67 may be used as long as it has a binder function while melting by heating, but it does not have a thermal insulation function that prevents heat transfer when bonded between the refrigerant pipe 65 and the bracket 66. Naturally, it is necessary to use bonded vinyl.

That is, the bonded vinyl 67 may be used by adopting any one of the well-known materials used in various fields that does not have a heat insulating function.

When the refrigerant pipe 65 and the bracket 66 are bonded to each other, the bracket bending step is performed. That is, as illustrated in FIG. 10, the bracket bending step may include the shape of the incase 41 so that the bracket 66 to which the coolant pipe 65 is joined may be attached over the rear and side surfaces of the incase 41. By bending in accordance with, the step of configuring the evaporator (64).

Then, when the configuration of the evaporator 64 is completed through the bracket bending step, the evaporator mounting step is performed.

That is, as shown in Figure 10, the step of mounting the evaporator is the step of mounting the completed evaporator 64 in the case 41, in the case of the evaporator 64 completed in the form of a depot like in the prior art It mounts over the back and side surfaces of (41).

In this case, the evaporator 64 may be mounted in the incase 41 in the same manner as that of mounting the bracket on the incase of the conventional drawer storage compartment.

As described above, as an embodiment to which the present invention is applied, the assembly structure of the evaporator has been described, but is not limited thereto.

That is, in fixing the refrigerant pipe 65 to the bracket 66 made of the aluminum sheet, it is possible to use the bonding vinyl 67 as described above, but can be fixed by fastening with a conventionally known bolt or the like. It will be apparent, and it will be understood by those skilled in the art that various modifications and variations are possible within the equivalent scope of the technical spirit of the present invention and the claims to be described below.
