CONSTITUTION: A user settles a beverage container(9) needing quick cooling in a pocket(7) of a door(3) of a cooling chamber and turns on an operation switch to operate a vibrator(16) and a fan(21) of a humidifier(10). Then the cool air of the cooling chamber sucked inside a fan duct(20) via an inlet(23) blows to a spray duct(17) of the humidifier via a vent hole(51) according to the driving of the fan. Accordingly, the blowing cool air forms humidifying cool air by being mixed with spray particles staying in the spray duct. The humidifying cool air is flowed into a humidifying duct(30) via a spray outlet(15) of the spray duct by the blowing power of the fan. The humidifying cool air flowed into the humidifying duct is vented to the pocket via multiple spray outlet holes(31) opened on the wall of the duct and given to the beverage containers concentrically. Therefore, the beverage container is cooled more quickly by the evaporative latent heat taking the heat while evaporating by the contact with the container.

Description

Humidifier of refrigerator for cooling of door pocket

The present invention relates to a humidifier of a refrigerator, and more particularly, by using a mixed humidifier by mixing a humidification spray to the cold air introduced through a separate humidification duct installed in the refrigerator door inner side and installed in the longitudinal direction of the door. The present invention relates to a humidifier for cooling a door pocket of a refrigerator to intensively humidify various types of beverage containers and the like stored in the door pocket.

Generally, a refrigerator is a device for maintaining freshness for a long time by storing various foods in a frozen and refrigerated state. A direct cooling method of installing and cooling the food through direct heat exchange of the evaporator and food by installing an evaporator of a cooling unit in a food storage space. And, an indirect cooling method is used in which the evaporator is installed on a passage separated from the food storage space and the heat exchanged through the evaporator is forced to circulate through the blowing force of the cooling fan to cool the stored food.

As such an indirect cooling refrigerator, the refrigerator as shown in FIG. 1 is mentioned conventionally. This refrigerator is provided with a separation wall 101 installed in the middle in the middle so as to be divided into a freezer compartment 110 and a refrigerating compartment 120 in a vertical direction, and the evaporator 130 installed on the rear wall of the freezer compartment 110 as in a general refrigerator. It is supposed to generate cold air. The cold air generated in this way is blown by the blowing fan 140 installed adjacent to the evaporator 130 and supplied to the freezing chamber 110 and the refrigerating chamber 120 through the respective discharge passages 111 and 121, and the suction passages 113 and 123. By returning back to the evaporator 130, the entire inside of the refrigerator is circulated. At this time, the cool air flowing into the refrigerating chamber 120 through the discharge passage 121 is controlled by the damper 125 is operated controlled according to the current temperature of the refrigerating chamber 120.

However, such a conventional refrigerator circulates cold air in the entire refrigerator through the discharge passages 111 and 121 and the suction passages 113 and 123, and can control the temperature inside the refrigerator as a whole, and quickly and effectively to any specific portion. It has a structure that cannot be cooled strongly.

Therefore, when the user wants to quench the beverage container at room temperature urgently, the cooling system of the whole refrigerator is strongly operated, or the cooling rate of the container is accelerated by using the latent heat of evaporation of water buried in the container. As the cooling system is operated more powerfully than necessary, there is a problem in that energy consumption is unnecessarily increased or inconvenience in use is caused.

As another example, a refrigerator having a humidifier such as the refrigerator humidifier described in Korean Patent Publication No. 97-7245 has been developed.

The refrigerator humidifier is configured to properly maintain the humidity of the archival chamber 213, and as shown in FIG. The moisture supply pipe 217 is opened and closed through the valve 216 to supply moisture from the defrost water collected in the evaporation water tank 215 to the vegetable chamber 213 to effectively maintain the humidity of the vegetable chamber 213. According to the humidification device, only the vegetable chamber 213 can be humidified, and thus, unless the user keeps the beverage container that the user wants to rapidly cool in the vegetable chamber 213, that is, the beverage container is normally stored in the door pocket. There was a problem that can not be cooled rapidly.

In addition, in order to solve the problems of the conventional humidifying refrigerator as described above, a humidifying refrigerator having a humidifying duct as shown in FIGS. 3 and 4 is proposed as a Korean Utility Model Registration Application No. 98-10550 have.

The refrigerator 301 has a suction branch passage 311 which is arranged in the longitudinal direction at the rear end of the right side wall of the interior 302 as shown, and the right side wall which is the other side wall of the suction branch passage 311. It is arranged in a plurality of branches in the longitudinal direction in the end portion is configured to include a discharge branch passage 313 is formed through the discharge hole (313a) for discharging the air sucked into the interior 102, humidification at one lower end portion A humidifier 330 for discharging particles is provided, and a blower fan 320 for forcibly sucking air in the interior 302 and discharging the sucked air into the interior 302 together with the humidified particles is provided.

Here, the humidifier 330 is installed in communication with the inside of the lower surface of the duct 310, the humidification tank 333 containing a predetermined amount of water, and a bucket for supplying water intermittently to the humidification tank 333. 331, a vibrator 335 installed on the bottom surface of the humidification tank 333 to atomize the water with ultrasonic waves, and humidifying particles provided on the upper part of the humidification tank 333 to be atomized by the vibrator 335 It is composed of a spray pipe 337 for guiding discharge into the interior of the 310, one side of the humidification tank 133 is provided with a float switch 339 for detecting the minimum level of the humidified water.

Therefore, according to the refrigerator 301, in the process of refrigerating food while cooling air is circulated from the cooling unit to the inside of the refrigerator 302, the humidifier 330 is driven and the fan 320 is driven at the same time so that the suction basin passage 311. Humidification by vibration of the vibrator 335 while inhaling cold air in the interior 302 through each suction hole 311a and discharging it into the interior 102 through each discharge hole 313a of the discharge branch passage 313. The humidifying water in the tank 333 is atomized to humidify the cold air.

As described above, the refrigerator 301 circulates humidified cold air into the inside of the refrigerator 302, thereby adding moisture to the food to improve the freshness of the food, and at the same time, to increase the cooling effect of the food through heat absorption due to evaporation of moisture. It is. Furthermore, by adjoining each discharge hole 313a of the discharge branch passage 313 to the door 301a side, the pocket part of the door 301a can be intensively cooled by the humidification cooler.

However, in the case of the refrigerator 301, as illustrated in FIG. 4, humidification ducts 310 and 311 are installed inside the storage unit of the interior 302, and a humidifier 330 is installed inside the humidification ducts 310 and 311. Since it will occupy a lot, inevitably the storage space of the interior 302 is greatly reduced, and since the humidifier 330 is installed in the interior of the interior 320, it is necessary to remove all stored refrigerated products in order to replace the bucket 331. There was a problem that the maintenance of the humidifier 330 is cumbersome.

In particular, in order to rapidly cool a beverage container in which the compartment is stored in the pocket of the door 301a, the discharge branch passage 313 must be provided in multiple, as shown in FIG. 3, so that the structure of the discharge duct is complicated. Since the humidifying chiller is supplied to the pocket part via the space in the refrigerator 302, there was also a problem in that the refrigerator can be rapidly cooled to the refrigerated product in the refrigerator 302, which does not need rapid cooling.

Therefore, the present invention was devised to solve the problems of the conventional refrigerator and the humidifier as described above, by mounting a humidifier on the inner surface of the refrigerator door to humidify the cold air supplied from the refrigerating chamber, the pocket of the refrigerator door By installing a separate humidifying duct across the unit, the Kankan can supply the cold air humidified by the humidifier to the pocket to rapidly cool the beverage container stored in the pocket and at the same time, such as changing the bucket of the humidifier. The purpose is to improve the convenience and ease of production.
