Description

Ice Water Purifier with Auxiliary Tank {WATER PURIFIER HAVING ICE-MAKER}

The present invention relates to an ice water purifier provided with an ice making unit, and more particularly, to an ice water purifier having an auxiliary tank capable of efficiently generating ice using an auxiliary tank.

In general, ice water purifier is a device for supplying purified water, cold water and / or hot water and ice to the user by purifying raw water, such as tap water. An ice water purifier typically includes a filter unit for purifying raw water, a purified water tank for storing purified water, a cold water tank for cooling purified water, and an ice making unit for making ice, and a hot water tank for heating and storing purified water. It can be provided as.

Such ice water purifiers are typically provided with ice trays for receiving raw water for ice making from water tanks to cool the ice water contained in the drip trays by the ice making unit to generate ice.

However, since the water contained in the purified water tank is close to room temperature, there is a problem in that it takes a lot of power and time to cool the ice making raw water contained in the ice making drip tray to generate ice.

In order to solve this problem, the method of cooling the cold water tank by supplying the water cooled first in the cold water tank to the ice making drip tray to generate ice and supplying the raw ice water remaining in the ice making drip tray to the cold water tank again. It has been proposed.

As an example, Korean Patent No. 729962 discloses a method of providing a cooling means to a cold water tank and an ice making unit using one compressor and two evaporators (Korean Patent No. 407867), resulting in an increase in cost due to an increase in the capacity of the compressor. In order to solve the problem that not only the energy consumption increases but also the noise of the compressor increases, an ice water purifier that does not employ a separate cooling means in the cold water tank is disclosed.

The ice water purifier disclosed in the above-mentioned Patent No. 729962 supplies water contained in a cold water tank to an ice making drip tray to generate or cool ice by an ice making unit, and rotates the ice making drip tray to generate water remaining in the ice tray after ice formation. Or it has a configuration to cool the cold water tank by re-supply the water cooled to a predetermined temperature by the ice making unit to the cold water tank.

Since the conventional ice water purifier adopts a method of generating ice by using water cooled in a cold water tank primarily and cooled in a cold water tank, it may be efficient when the temperature of the cooling water contained in the cold water tank is low. As a lot of room temperature water flows into the cold water tank from the tank, a problem arises that the water temperature of the cold water tank rapidly increases.

That is, when the extraction amount of cold water is large in a short time, when the water level of the cold water tank is lowered and the water level of the cold water tank is lowered by the low water level sensor of the cold water tank, a large amount of room temperature water is introduced from the purified water tank, The temperature of the water rapidly rises, and the temperature of the ice making raw water supplied from the cold water tank to the ice making drip tray to generate ice becomes close to room temperature.

In particular, the ice water purifier of the patent because the volume of the cold water tank for supplying a large amount of cold water is a certain degree or more, since the water temperature of the cold water tank is increased by the supply of room temperature water from the purified water tank there is no separate cooling means in the cooling tank Only cooling the water contained in the ice-making drip tray takes a considerable time to lower the temperature of the cold water tank, and there is a problem in that the efficiency of producing ice using the cooling water contained in the cold water tank is considerably reduced.

It is a schematic diagram showing a state in which ice is introduced into the ice storage in the ice purifier, Figure 6 is a schematic diagram showing a state in which the ice is introduced into the cold water tank in the ice purifier shown in FIG.

First, the ice water purifier 100 according to the first embodiment of the present invention will be described with reference to FIG. 1.

As shown in FIG. 1, the ice water purifier 100 according to the first embodiment of the present invention has a space formed therein and includes an auxiliary tank 130 for receiving water and water supplied from the auxiliary tank 130. Using ice as raw water for ice making or ice making unit 210 for cooling raw water for ice making and water for guiding the raw water for ice remaining in the ice making unit 210 to be recovered to the auxiliary tank 130. It comprises a guide member 160.

The auxiliary tank 130 accommodates the water supplied from the purified water tank 110 through the water supply pipe 170 therein, and the ice tray drip 190 through the pump 155 and the ice water supply pipe 150. ) Will supply the raw water for ice making. Here, the purified water tank 110 is to accommodate the water filtered through a filter unit (not shown) consisting of a plurality of filters, and has a configuration similar to that used in a conventional water purifier, so a detailed description thereof will be omitted.

At this time, the immersion pipe 221 provided in the ice making evaporator 220 of the ice making unit 210 is supplied from the auxiliary tank 130 is immersed in the raw water for ice making accommodated in the ice receiving tray 190, the ice making unit 210 As the ice is driven, ice is formed around the immersion tube 221.

When ice is formed by the operation of the ice making unit 210, a task for de-icing is performed. For ice removal, the ice tray drip 190 is rotated about the rotating shaft 191 through a drip drive means (see 192 'of FIGS. 3 and 4) such as a rotating motor (in the case of FIG. 1, clockwise). At this time, the water remaining in the ice tray 190 drops down.

In addition, in the state in which the ice tray 190 is rotated for deicing, the evaporator 220 is supplied with hot gas for deicing to separate the ice attached to the immersion tube 221. Since the structure of the ice making unit 210 and the ice making / defrosting process are widely used in various methods in the conventional ice water purifier, detailed description thereof will be omitted.

Unlike the foregoing, the temperature of the ice-making raw water accommodated in the ice-making drip tray 190 is not frozen by controlling the driving timing of the ice-making unit 210 and / or the drip driving unit (see 192 'of FIGS. 3 and 4). It is also possible to produce only low cooling water.

On the other hand, the structure of the ice making unit 210 used in the present invention and the operation for deicing / defrosting can adopt a variety of conventional structures and forms within the scope without departing from the spirit of the present invention, for example, Rather than being immersed, a method of cooling the drip tray for ice making with partitions as a whole may be adopted.

In addition, the water guide member 160 guides the raw water for ice making remaining in the ice making unit 210 to the auxiliary tank 130, and the raw water for ice making remaining in the ice making unit 210 is transferred to another member.
