The present invention relates to a refrigerator equipped with a carbonated water dispenser, and more particularly, a carbon bay for producing carbonated water is installed in a door, and the purified water and carbon dioxide gas supplied from the inside of the refrigerator are mixed by maintaining a constant temperature in the Bombay to produce carbonated water. It is about a refrigerator to generate and provide to the dispenser.

In general, a refrigerator has a function of storing food, but various functions are applied for convenience of use. A dual function may be a refrigerator supplying carbonated water. A diagram showing such a refrigerator is shown in FIGS. 1 and 2. That is, the water tank 13 for water supply and the compressed carbon gas cylinder 15 for carbon gas are formed in the refrigerator, and the carbonated water mixing bomb bay 22 is formed by receiving water and carbon therefrom to generate carbonated water. Carbonated water is discharged to (27). This will be described in more detail as follows.

A water tank 13 is provided inside the refrigerator main body 10. The water tank 13 selects cold water or carbonated water from an operation panel unit (not shown) in which a user is usually installed at the front of the refrigerator to control the function of the refrigerator. When the cold water is supplied to the dispenser 27 or the carbonated water mixture Bombay 22 to supply water for the production of carbonated water.

In addition, the inside of the main body 10 is provided with a compressed carbon gas cylinder 15 for producing carbonated water. The water tank 13 and the compressed carbon gas cylinder 15 are connected to the purified water pipe 17 and the carbon gas pipe 18 to supply water and carbon dioxide gas to the carbonated water mixture bomb bay 22. Of course, the water tank 13 receives water through the water valve 11, which is a water supply source, and undergoes a purification process by the water filter 12 to receive fresh water.

In addition, since the water tank 13 is installed in the refrigerating chamber, it is naturally cooled by the circulation of cold air to maintain a constant temperature. FIG. 2 is a cross-sectional view of the door 31 and the body 30 as illustrated in FIG. 1 and shows the positions of the carbonated water mixing bomber 22, the compressed carbon gas cylinder 15, and the water tank 13.

By the way, according to the conventional configuration, the carbonated water mixing bomb bay 22 is usually configured inside the upper end of the freezing chamber door so that the temperature is drastically lowered due to cooling of the freezing chamber, whereby the mixing of carbon dioxide gas and water is hindered and thus the carbonated water production is disturbed. There are disadvantages. In addition, according to the installation of the mixing bomb bay 22 has a disadvantage that the heat insulation foam thickness is thinned and the cold air inside is discharged to the outside to increase the power consumption.

The present invention has been conceived to overcome the disadvantages of the prior art described above, to provide a refrigerator having a structure for the carbonated water mixing Bombay for carbonated water production in the refrigerator equipped with a carbonated water generator to facilitate the carbonated water production Has its purpose.

In addition, another object of the present invention is to provide a refrigerator having a structure for reducing cold air leakage caused by thinning of the insulation foam thickness according to the installation of the carbonated water mixing bomb bay.

In order to solve the above object, the present invention is equipped with a Bombay for the production of carbonated water in the freezer compartment door and by maintaining a constant temperature in the Bombay, purified water and carbon dioxide gas supplied from the inside of the refrigerator are mixed to produce carbonated water and supplied to the dispenser. Provide a refrigerator.

To this end, a carbon dioxide gas pipe into which gas is introduced from a compressed carbon gas cylinder installed on a high tomorrow side, a purified water pipe in contact with the gas cylinder on a high tomorrow side, into which water is introduced, and the carbon dioxide gas and the purified water are mixed to generate carbonated water. A carbonated water mixing bomb bay, a water level sensor for detecting the level of carbonated water generated in the mixed bombay, a pressure valve for discharging the gas when the carbon dioxide gas introduced into the mixed bomb bay is above a predetermined pressure, and connected to the pressure valve A refrigerator having an overpressure carbon dioxide discharge pipe for discharging overpressure carbon gas and a carbonated water discharge pipe for discharging carbonated water generated in the Bombay to a dispenser formed outside the refrigerator, wherein the refrigerator has a predetermined thickness in the freezer compartment at the upper end of the freezer door. A pocket changer is formed to hold the carbonated water inside the pocket changer. A sparkling blend of Bombay Province is installed.

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

The structure of a refrigerator for producing carbonated water has been described with reference to FIGS. 1 and 2 in the prior art. For easy understanding of the present invention, it will be described in detail with reference to FIGS. 1 to 1 as follows.                     

The fresh water maintains a constant temperature (10 ° C. or less) as the water tank 13 inside the refrigerator is cooled by a cooling cycle in the refrigerator, and thus, the fresh water is easily mixed with carbon dioxide gas. Of course, it is also possible to branch off a separate pipe from the purified water pipe 17 without supplying carbon dioxide gas and supply cold water to the purified water dispenser tap 25 through the first discharge valve 23.

The cooled water flows into the carbonated water mixing bomb bay 22 formed inside the door 31 through the purified water pipe 17. Of course, the pressure pump 16 is used to take the water from the low place to the high place. That is, water is used to flow upward along the purified water pipe 17. Water introduced into the purified water pipe 17 is introduced into the mixing bomb bay 22 through the purified water pipe valve 20.

In addition, carbon dioxide gas has to be injected into the mixed bomb bay 22 in order to generate carbonated water. To this end, the compressed carbon gas cylinder 15 is placed at the bottom of the water tank 13. Of course, the carbon dioxide cylinder 15 may be installed inside and outside the cabinet (upper cabinet or inside the refrigerator compartment). However, in the present invention, in order to facilitate the maintenance of carbon dioxide gas, it is preferable to install in the refrigerating chamber. The compressed carbon gas cylinder 15 has an internal pressure of 10 to 100 atm, reduced to 1 to 10 atm, and then ejected to the gas pipe valve 21 through the carbon dioxide pipe 18 to be introduced into the carbon dioxide mixing bomb bay 22. do.

Carbonated water is produced by mixing water and carbon dioxide gas in the mixing bomb bay 22, and when the user turns on the carbonated water supply lever (not shown), the carbonated water dispenser tap (2) is discharged through the second discharge valve (24). 26) carbonated water is supplied.                     

Therefore, the carbonated water mixing bombay 22 for producing the carbonated water described above is usually placed inside the upper end of the freezer door. In the case of the dispenser-type refrigerator, the thickness of the existing freezer door varies slightly depending on the manufacturer and model, but is approximately 5 cm to 10 cm. Therefore, when the carbonated water mixture bomb bay 22 is configured in the freezer door, heat loss is blocked between the inside and the outside of the refrigerator. Insulation foam thickness is reduced significantly. In other words, if the freezer door is configured to have the same thickness as the freezer door of the conventional refrigerator, the cold air inside the refrigerator is easily flowed to the outside, which increases the power consumption of the refrigerator and the internal temperature of the freezer door may drop below zero. This is high. Therefore, the carbonated water mixture bomb bay 22 is frozen, causing a malfunction. A diagram showing a temperature graph to illustrate this is shown in FIG. 3.

That is, Figure 3a shows a side cross-sectional view of the conventional freezer compartment door 31, the upper pocket 32 and the lower pocket 33 is configured in the door, respectively. The dotted line indicates the center line of the door. A temperature distribution graph is made when the inner temperature is T _O and the outer temperature is T _f based on the center line. A diagram showing this temperature distribution graph is shown in FIG. 3B.

If you assume that the insulation component distribution in the refrigerator uniform as described above illustrated in Figure 3b, the central portion of the panel thickness direction, the median of the door outside temperature (room temperature) and the temperature inside the freezer compartment (i.e. T + _O T _f / 2). For example, if the door outer wall temperature is 18 ° C image and the freezer inner temperature is minus 20 ° C, the median value is as follows.

T _O + T _f / 2 = 18 ° C-20 ° C / 2 = -1 ° C

That is, the temperature of the center portion of the freezer door 31 is placed in an environment of minus -1 ° C, and when the carbonated water mixture bombay 22 is present at the corresponding position, the remaining water in the bombay freezes so that carbon dioxide cannot be mixed. Manufacturing is virtually impossible.

Therefore, by removing the upper pocket 32 on the inside of the freezer compartment door to form a space for the carbonated water mixing bombay 22 to maintain a constant temperature to generate carbonated water. This space is called the pocket change part 50.

Prior to such a structure of the pocket changer 50, the structure of the mixing bomb bay 22 will be described for ease of understanding. 4 is a block diagram showing the configuration of the carbonated water mixing bombay for producing carbonated water according to the present invention, the purified water pipe 17 to allow the purified water to flow into the top of the carbonated water mixed bombay 22, so that carbon dioxide gas can be injected The carbon dioxide gas pipe 18, the pressure valve 40 for discharging carbon dioxide gas by the pressure of the excessively injected carbon dioxide gas, the overpressure carbon dioxide gas discharge pipe 41 which is a carbon dioxide gas discharge passage, and the generated carbonated water are adjusted to a predetermined level. The water level sensor 43 is configured to. At the lower end, the carbonated water discharge pipe 40 for discharging the generated carbonated water to the carbonated water dispenser tap 26 is configured.

5 is a view showing a front view of the carbonated water mixing bombay 22 and the pocket changer 50 described above. That is, Figure 5 shows a case of a two door type refrigerator (Two door type), wherein the left door is a freezing chamber door 51 is a carbonated water mixing bomb bay 22 and a pocket change unit 50 on the upper end of the freezer chamber door. Of course, the drawings are shown for ease of understanding, but are actually constructed inside the door and are not visible from the outside. The right door is a refrigerating chamber door 52.                     

5 is a cross-sectional view taken along the X-Y axis of FIG. 5. Unlike the front view of FIG. 5, the freezing chamber door 51 is a side cutting surface of the refrigerator, and the carbonated water mixing bomber 22 and the pocket change unit 50 described above are displayed. In addition, a dispenser 27 for discharging the generated carbonated water and a lower pocket portion 60 for allowing a beverage or the like to be seated inside the door are formed.

In general, even if the mixed bomb bay 22 is configured as thin as possible, because it is inevitable to configure the thickness of 3 to 5 cm, if you consider other additional devices in addition to the mixed bomb bay 22, the additional space of about 5 to 10 cm In the present invention, by removing the upper pocket 32 installed on the upper part of the existing freezer compartment, and increasing the door thickness by the removed space, a sufficient insulation foam thickness as well as a space for the mixing bomb bay 22 is secured.

As mentioned above, the present invention has been described in detail with reference to the accompanying embodiments and drawings, but the present invention is not limited to the specific embodiments, and those skilled in the art or acquiring general knowledge are provided with the contents of the present invention. It should be understood that numerous variations and modifications can be made without departing from the scope of the invention. Therefore, the protection scope of the present invention will be preferred based on the appended claims.

According to the present invention, in a refrigerator equipped with a carbonated water generator, a pocket change part is provided inside a door in which a carbonated water mixing bombay for carbonated water production is configured, so that a constant temperature can be maintained and carbonated water can be generated smoothly.                     

Another effect of the present invention is that by increasing the insulation foam thickness of the door is composed of the mixed bomb bay, the cold air outflow is reduced to reduce the power consumption.
