Description

Cooling device for draft beer {A cooling device of draft beer}

The present invention relates to a draft beer cooler for instant cooling draft beer.

In general, draft beer is cooled to cool enough to feel the taste. Draft beer container containing draft beer is not equipped with a cooling device is used to cool the draft beer using a separate cooling device.

The draft beer cooler according to the prior art sucks and compresses a refrigerant in a lower portion of the cooler main body 100 as shown in FIG. 5, and sends the compressor to a condenser in a gas state of high temperature and high pressure, and forcibly cools the refrigerant sent from the compressor by an electric fan. Is equipped with a receiver dryer for removing water and dust from the condenser and the liquefied refrigerant, and an expansion valve. The evaporator evaporates through the expansion valve in the middle of the cooling water tank 200 in which the refrigerant in a low temperature and low pressure mist circulates. The pipe 300 is installed in a twisted state in a spiral shape, and the draft beer pipe 400 in which the draft beer circulates is wound in a spiral shape inside the evaporation pipe 300, and the cooling water contained in the cooling water tank 200 at the upper portion thereof. The motor for rotating the rotary blade 500 to flow in the vortex state is installed.

However, the conventional draft beer cooler as described above is installed in a state in which the spirally evaporated tubes 300 twisted in a spiral are installed in a single line in a state in which the evaporation tubes 300 take heat of the cooling water. Due to the phenomenon that the action is actively progressed on the outer surface of the evaporation tube 300, the phenomenon that the cooling water is frozen on the outer circumferential surface of the evaporation tube 300 appears, this phenomenon is the rotary blades 500 for flowing the cooling water is operated The cooling water is frozen on the outer circumferential surface of the evaporation tube 300, and thus the cooling water is frozen on the outer circumferential surface of the evaporation tube 300, so that the heat exchange action of the evaporation tube 300 does not reach the draft beer tube 400. In addition, the cooling water of the cooling water tank 200 may not be cooled, thereby causing a problem in that it is impossible to cool the draft beer circulating in the draft beer tube 400.

In addition, since the evaporation tube 300 and the draft beer tube 400 mounted therein are also installed in one line in a spiral shape, the draft water tube spirally wound up and down with the cooling water flowing by the rotation operation of the rotary blade 500. Blocked by the 400 and the evaporation tube 300, the flow does not proceed smoothly, there is a problem that the outer circumferential surface of the evaporation tube 300 is frozen quickly appears, and draft beer 400 itself in a spiral line Since the draft beer circulating in the draft beer pipe 400 stays in the cooling water tank 200 because it is installed, there is a problem such that the draft beer is not cooled well and thus the draft beer is not cooled instantly.

The present invention was created in order to solve all the problems of the prior art as described above, in the installation of the evaporator tube of the evaporator in the spiral in the cooling water tank of the cooler main body is installed to be wound in a spiral while spaced apart in the upper and lower zigzag phase. As a means to prevent the heat exchange action between the evaporation tube stacked up and down so that the cooling water does not freeze on the outer circumferential surface of the evaporation tube to facilitate the heat exchange action of the evaporation tube, the evaporation tube Spiral winding with up and down zigzag is spaced to form a sufficient space between each other, so that the flow of cooling water proceeds smoothly, and the whole cooling water is exchanged with the evaporation tube for different purposes. In addition, the draft beer circulating in the draft beer is cold It was designed for another purpose to extend the time spent in each tank to ensure good cooling.

Draft beer cooler is equipped with a draft beer inlet for discharging and drafting the coolant, and a draft beer inlet for sucking the draft beer contained in the draft beer cylinder and the draft beer in the draft beer container, and a draft beer outlet for discharging the draft beer circulated through the draft beer tube. ,

The draft beer tube has a double structure wound up and down stacked in a spiral shape on the inside and the outside, and the evaporator is formed by winding in a spiral shape so that the evaporation tubes of parts facing each other are alternately stacked up and down in a zigzag shape. It is characterized by

Reference numeral 1 denotes a cooler main body, in which a compressor 2 and a condenser 3 are mounted on the lower part of the cooler main body 1, and an evaporator 5 and a draft beer tube 6 are mounted in the cooling water tank 4 in the middle part. ) Constitutes a refrigeration cycle.

The compressor (2) serves to inhale and compress the refrigerant in the evaporator (5) and to send it to the condenser (3) in a gas state of high temperature and high pressure. The condenser (3) has a fan motor for forcibly cooling the refrigerant; A fan and a condensation tube 31 through which the refrigerant circulates are provided.

The refrigerant circulating in the condenser tube 31 of the condenser 3 enters the receiver dryer 32 to remove moisture and dust, and then enters an expansion valve (not shown). The high pressure liquid refrigerant entering the expansion valve is As it rapidly expands, it is introduced into the evaporator 4 as a low temperature low pressure fog state.

The evaporator (5) is stacked up and down while the evaporation tube (51) in which the refrigerant circulates is wound in a spiral shape, and both side portions supported by the support (52) are spiral wound in a state where the cross section is arranged in a vertical line. On the other hand, the other two side parts are stacked in a state where the cross sections are spaced apart from each other in the upper and lower zigzag phases while spirally winding, so that the upper and lower zigzag layers are laminated to expand the heat exchange area with the cooling water, thereby cooling. Simultaneously, the cooling water does not freeze on the outer circumferential surface of the evaporation tube 51, and the cooling water flows smoothly.

The draft beer tube 6 extends the entire length of the draft beer tube 6 spirally installed in the cooling water tank 4 by winding the inner portion spirally and then winding the outer portion spirally to have a double structure. It is possible to improve the cooling action by extending the time the draft beer circulating the draft beer tube (6) stays in the cooling water.

Both ends of the draft beer tube 6, that is, the draft beer suction port 61 and the draft beer discharge port 62 protrude to the upper front surface of the cooler body 1 to supply a draft port of the draft beer container 7 (draft beer draft to the draft beer tube) ) And the discharge port (valve to discharge the draft beer discharged from the draft beer to the outside) by a hose or the like.

The upper part of the cooler main body 1 is provided with a motor 8 for rotating the rotary blade 81 for flowing the cooling water of the cooling water tank 4 in the vortex state, the rotary shaft 82 of the rotary blade 81 Cooling water inlet 92 is formed on one side of the support cylinder 91 rotatably surrounding the (), the pump (9) integrally formed at the bottom of the support cylinder 91 pumps the cooling water to coolant discharge port (93) And a cooling water circulation hose 95 connected to the cooling water inlet 94, and the cooling water circulation hose 95 spirally winds around the outer circumference of the draft beer cylinder 7 in a draft beer cylinder 95. ) Can be pre-cooled.

The pump 9 and the cooling water discharge port 93 are connected to the connection hose 96, and a hose for returning the cooling water circulated through the cooling water circulation hose 95 to the cooling water tank 4 at the cooling water suction port 94 (not shown). Are omitted).

In addition, the four sides of the cooling water tank 4 and the upper and lower portions are provided with a heat insulating material 41 made of urethane material, and the bottom 11 corner portion of the cooler body 1 is attached with wheels 11 to facilitate movement. It is.

The operation of the present invention configured as described above will be described.

First, when the power switch installed on one side of the cooler main body 1 is turned on, the compressor 2 and the fan motor of the condenser 3 are operated to operate the refrigeration cycle for circulating the refrigerant. In addition, the motor (8) and the pump (9) mounted on the upper portion of the cooling water tank (4) is driven to rotate the cooling blade (81) while flowing the cooling water in a vortex state and the simultaneous cooling water is pumped to cool water circulation hose (95) The cooling water is circulated.

The compressor (2) and the condenser (3) has the same function as the conventional refrigeration cycle, but the evaporator (5) mounted on the cooling water tank (4) is the evaporator tube 51 wound in a spiral upper and lower zigzag shape Since the heat exchange range with the cooling water is widened and a sufficient space is formed between the evaporation tubes 5, the phenomenon of heat exchange between the evaporation tubes 5 can be eliminated. Since it does not freeze can be expected to improve the cooling action, and sufficient separation space between the evaporation tube 51 is a cooling water flowing in the vortex state by the rotary blade 81 flows smoothly between the evaporation tube 51. By doing so, the heat exchange operation between the evaporation tube 51 and the cooling water is made smoothly, thereby improving the cooling efficiency of the cooling water.

In addition, the draft beer tube (6) spirally wound inside the evaporator (5) is installed in a double structure so that the draft beer tube (6) is longer than that of the conventional chiller, thus the draft beer tube (6) After the draft beer is circulated in the cooling water tank (4) is long, the draft beer sucked into the draft beer inlet (61) is sufficiently cooled while circulating the draft beer tube (6) wound in a double structure in the state of being precipitated in the cooling water It is possible to provide a cool draft beer by being discharged to the draft beer outlet (62).

Meanwhile, the cooling water of the cooling water tank 4 is pumped by the pump 9 to circulate to the cooling circulation circulation hose 95 through the cooling water discharge port 93, and the cooling water circulation hose 95 is a draft beer cylinder 7. Since the spiral wound around the outer peripheral surface of the cooling water circulation hose (95) serves to cool the draft beer (7), the cooling action of the cooling water circulation hose (95) is the cooler body (1) Since the refrigeration cycle mounted therein is continuously made, the draft beer container 95 is also continuously cooled by the coolant, so the draft beer contained in the draft beer container 7 is primarily cooled in the draft beer tube ( 6) will be able to further improve the cooling efficiency of draft beer.

In the present invention as described above, in winding the evaporator tube of the evaporator installed in the cooling water tank of the cooler in a spiral form, the cooling zone of the cooling water is expanded while being installed in a state in which the upper and lower zigzag layers are alternately stacked. The stacked evaporation tubes form a sufficient space therebetween so that heat exchange between the evaporation tubes is excluded, so that the cooling water does not freeze on the outer circumferential surface of the evaporation tube, so that the heat exchange action between the evaporation tube and the cooling water is smoothly performed. In addition, it is possible to install the length of the draft beer tube itself by spiral winding the draft beer tube installed inside the evaporator in a double structure to improve the cooling efficiency of the draft beer by extending the time the draft beer circulating the draft beer tube stays in the cooling water It can be effective, and also spirally wound around the outer circumference of the draft beer By circulating the cooling water of the cooling water tank in the cooling water circulation hose, the draft beer contained in the draft beer is continuously cooled, so that the draft beer passes through the draft beer in the state in which the draft beer is primarily cooled in the draft beer cylinder, thereby further improving the cooling efficiency of the draft beer. It is a useful design that has the advantage of always providing a cold and cool draft beer because it can be expected to be effective.
