It can reduce wear and tear of the ice-breaking unit in contact with the ice.

Hereinafter, an ice maker according to the present invention will be described with reference to FIGS. 1 to 5.

1 is a flowchart of an ice maker according to an embodiment of the present invention, FIG. 2 is a perspective view partially cut the drum for the ice maker of FIG. 1, FIG. 3 is a perspective view of the drive shaft and the ice maker of FIG. 2, and FIG. Fig. 5 is a plan view for explaining the arrangement of the icemaker, and Fig. 5 is a partial perspective view for explaining the arrangement of the icemaker.

As shown in FIG. 1, the ice maker 100 includes a compressor 111, a condenser 113, an expansion valve 115, and an evaporator 200.

The compressor 111 compresses the high temperature gaseous refrigerant passing through the refrigerant pipe 117 to high pressure and circulates the refrigerant.

The refrigerant compressed to high pressure is condensed in the condenser 113 to change into a high pressure liquid state.

Since the refrigerant exiting the condenser 113 is a high pressure, the boiling point is high and difficult to change into a gas, thereby lowering the pressure of the refrigerant in the expansion valve 115. As a result, the refrigerant may be easily evaporated even at a relatively low temperature. If the pressure of the refrigerant is not lowered, the boiling point is high and the refrigerant does not evaporate and thus cannot absorb heat.

That is, the low pressure liquid refrigerant in the evaporator 200 is converted into a gaseous refrigerant to absorb the surrounding heat. Accordingly, the ice-making water flowing down along the ice making unit 213 of the drum body 211 in contact with the refrigerant unit 215 absorbs heat and the refrigerant cooled by the expansion valve 115 may rapidly change into ice.

The evaporator 200 includes a drum unit 210, a drive unit 220, and a defrosting unit 250. The evaporator 200 further includes a heat keeping unit 230 and a drum support unit 240 for supporting the drum unit 210 and the like. A buffer member such as rubber may be inserted between the drum support unit 240 and the drum unit 210.

The drum unit 210 includes a drum-shaped drum body 211 and a drum body 211 having an ice making unit 213 formed therein in which ice making water flows down through the ice making nozzle 227 and the ice making water rapidly becomes ice. It is provided on the outside of the) to guide the refrigerant to absorb heat from the ice making water comprises a refrigerant unit 215 for evaporating to the refrigerant of the gas. That is, the ice making water in the ice making unit 213 is changed into ice by heat exchange between the ice making water and the refrigerant, and the ice making unit 213 is made of ice having a predetermined thickness.

The coolant unit 215 is a guide pipe or a flow path of the coolant to allow the liquid coolant to evaporate to become a gas.

The drive unit 220 includes a drive shaft 221 disposed in the center region of the evaporator 200 and having a long round rod shape, a drive unit 223 for providing a driving force to the drive shaft 221, a drive unit 223, and a drive shaft ( And a driving support part 225 coupled to the drum body 211 by supporting the 221. The driving unit 220 includes an ice making nozzle 227 that supplies ice making water to the ice making unit 213.

The heat insulating unit 230 surrounds the outside of the coolant 215 to prevent the cool air from the coolant 215 from being transferred to the outside.

The drum support unit 240 is coupled to the drum body 120 at the bottom of the drum body 120 to support the drum body 120.

The ice removing unit 250 removes or separates the ice formed in the ice making unit 213 from the ice making unit 213. The ice removal unit 250 is equipped with the ice removal support part 251 and the ice removal knife 253.

The ice removal support part 251 is coupled to the drive shaft 221 to support the ice removal knife 253 so that the ice removal knife 253 rotates by the rotation of the drive shaft 221. That is, the defrosting support part 251 has a structure in which one side is coupled to the drive shaft 221 and the other side supports the defrosting knife 253 with a bearing or the like so as to be rotatable.

As shown in FIGS. 3 to 5, the ice removal support part 251 includes an upper ice removal support part 251 a provided at an upper side, and a lower ice removal support part 251 b provided at a lower side thereof. When viewed from the rotational direction of the drive shaft, the upper ice removal support portion 251a has a structure that is later than the lower ice removal support portion 251b. That is, to prevent the ice falling from the ice removal knife 253 supported by the lower ice removal support 251b from interfering with the ice falling from the ice removal knife 253 supported by the upper ice removal support 251a. As shown in FIG. 4, the line formed by the "Y2" axis, which is the rotation axis of the drive shaft 221 and the lower icebreaking knife 253b, is the "Y1" axis, which is the rotation axis of the drive shaft 221 and the upper icebreaking knife 253a. It can be seen that the line is arranged so as to be preceded by the rotation direction of the drive shaft, and the leading angle is as much as "θ".

The ice removal knife 253 is supported by the ice removal support 251 to remove ice from the ice making unit 213 while rotating by contacting the ice of the ice making unit 213 by the rotation of the driving shaft 221. The ice-breaking knife 253 is arrange | positioned so that the center area | region of the ice-making part 213 may overlap. That is, referring to FIG. 5, the upper ice-breaking knife 253a removes the ice region (see “H1” in FIG. 5) above the ice making unit 213, and the lower ice-making knife 253b removes the lower ice. Remove the ice region below the ice (see section "H2" in Figure 5). Here, the ice-breaking knife 253 is coupled to the ice-breaking support 251 so as to have an intermediate region (see "H3" in FIG. 5) where the upper ice region H1 and the lower ice region H2 overlap. The ice formed in the ice portion 213 can be completely removed, so that ice can be formed again in the portion where the ice is completely removed, thereby increasing the ice making ability. In addition, the de-icing water flowing down by the unremoved ice is not only affected, but new ice is not formed in the portion where the ice is not removed, which may cause the de-icing ability to be reduced as a whole.

The icebreaking knife 253 includes a groove 255 formed in the circumferential surface 259 and a blade 257 formed in the circumferential surface 259 between the grooves 255. The groove 255 or the blade 257 is provided in the shape of a plurality of spirals along the rotational axes Y1 and Y2 of the ice-breaking knife 253. Thus, the defrosting knife 253 is provided with a plurality of spiral blades 257 has a blade 257 which can always contact the ice of the ice making unit 213, the drive shaft (221, 4 and 5 ' It can rotate itself according to the rotation of Y 'axis. Such blades may be formed of four, six, eight, etc., and may have various shapes, shapes, and numbers as necessary. The defrosting knife 253 may include various materials, but is preferably stainless steel in consideration of corrosiveness and the like.

By such a configuration, the ice maker 100 will be described with reference to FIGS. 1 and 2 as follows.

First, the refrigerant in a gas state flowing through the refrigerant pipe 117 is compressed into a gas of high temperature and high pressure in the compressor 111, and the compressor 111 also serves to circulate the refrigerant pipe 117.

The gaseous refrigerant compressed to high temperature and high pressure is condensed by the condenser 113 in the condenser. As shown in FIG. 1, the condenser 113 is a heat exchanger, but the condenser 113 may condense the refrigerant with a fan, such as an outdoor unit of an air conditioner. Here, the condensation of the refrigerant is made by heat exchange with water, and the water absorbing heat from the refrigerant is cooled by a cooling means 121 such as a cooling tower and circulated by the cooling water pump 123 to the condenser 113. Inflow.

The refrigerant, which is condensed and in a high pressure liquid state, is expanded by the expansion valve 115 to change into a low pressure liquid state, and flows along the refrigerant portion 215 of the evaporator 200 to evaporate to a gaseous state. In this process, heat exchange is performed between the refrigerant and the ice making water flowing along the ice making unit 213 formed on the inner wall of the drum body 211, and the ice making water rapidly decreases in temperature to become ice and forms an inner wall of the drum body 211. The refrigerant, which is attached and absorbs heat from the ice making water, becomes a high temperature gas state and exits the refrigerant unit 215 and flows into the compressor 111.

For example, the refrigerant passing through the expansion valve 115 is supercooled to minus 25 degrees Celsius (° C.) and flows into the evaporator 200. Accordingly, the refrigerant at minus 25 degrees Celsius passing through the refrigerant unit 215 takes away the heat of the ice making water flowing along the ice making unit 213 and rapidly cools it with ice, and the refrigerant evaporates to escape the refrigerant unit 215. It flows into the compressor 111.

In this process, the driving shaft 221 is continuously rotated by the driving unit 223 and the ice making nozzle 227 and the ice-breaking unit 250 also rotate according to the rotation of the driving shaft 221. The ice making nozzle 227 supplies the ice making water to the ice making unit 213, and the ice making unit 250 removes or separates the ice formed in the ice making unit 213 to a predetermined thickness from the ice making unit 213. The ice making nozzle 227 is disposed radially close to the inner wall of the drum body 120, and the ice making unit 250 is disposed in an inner region of the drum body 211 in which the ice making nozzle 227 is not disposed.

In this process, as the driving shaft 221 rotates, the ice removing support 251 also rotates with respect to the ice making unit 213 of the drum body 211, and the ice removing knife 253 coupled to the end of the ice removing support 251. The ice is rotated while being in contact with the ice of the ice making unit 213 by the ice-breaking knife 253 and at the same time breaking the ice in the ice making unit 213 to separate the ice from the ice making unit 213. Here, the distance between the ice making unit 213 provided on the inner wall of the drum body 211 and the blade 257 formed on the circumferential surface 259 is spaced about 0.5 mm apart.

Thus, rather than scraping and separating ice with a conventional knife, the ice removal knife 253 can remove ice while rotating, thereby reducing the load on the driving unit 223, thereby reducing the load on the driving unit, thereby making it possible to use it for a long time. It is more economical because it can reduce the back. In addition, since the wear and breakage of the icebreaking knife 253 can be reduced, it is easy to use and economical cost can be reduced.

The ice removed or separated from the defrosting unit 250 may be transferred or stored in the reservoir 119 provided immediately below and then supplied to a place where ice is needed.

Herein, the embodiments of the present invention have been illustrated and described, but it will be understood by those skilled in the art that the present embodiments may be modified without departing from the principles or spirit of the present invention. . It is intended that the scope of the invention be defined by the claims appended hereto and their equivalents.
