Pipes of an evaporator extending to the outside of the cooling water accommodating part can be embedded in the heat insulation part. Therefore, the heat insulation performance of the piping of the evaporator can be uniformly realized by surrounding the cooling water accommodating part and the piping of the evaporator at the same time.

Description

Technical Field

[0001] The present invention relates to a water purifier, and more particularly, to a water purifier that can be miniaturized. Background Art

[0002] Generally, a water purifier filters harmful elements such as foreign substances or heavy metals contained in raw water by physical and chemical methods.

[0003] The water purifier may have a function of manufacturing cold water and / or hot water.

[0004] To provide hot water and cold water, a heating device and a cooling device are additionally provided inside the water purifier. The heating device is a device that heats purified water to provide hot water to a user, and the cooling device is a device that cools purified water to provide cold water to a user.

[0005] The water purifier has a cooling module for cooling raw water supplied to a cold water pipe.

[0006] The cooling module may be composed of one of a thermoelectric element or a cooling cycle device. Among them, in order to achieve power consumption and cooling capacity above a certain level, the cooling module is used as the cooling cycle device.

[0007] Figure 1 FIG. is a perspective view of a water purifier having an existing cooling module provided in a water purifier. Figure 2 FIG. shows Figure 1 a perspective view of the cooling module of

[0008] Referring to Figures 1 to 2 , an existing water purifier has a main body 10 provided with a mechanical chamber. Devices such as a compressor 20 and a fan 12 are provided in the mechanical chamber.

[0009] A cooling module 30 is provided in the main body 10. A support device 11 for supporting the cooling module 30 is provided in the main body 10. A support member 11A is formed at the upper end of the support device 11, and the lower end of the cooling module 30 is inserted into the support member 11A and supported by the support member 11A.

[0010] Among them, the cooling module 30 and the compressor 20 may be provided in different regions inside the main body 10.

[0011] The cooling module 30 has a cold water tank 31. The upper part of the cold water tank 31 is open.

[0012] An internal space for storing cooling water is formed in the cold water tank 31. A heat insulating portion 40 formed by foaming a heat insulating material is formed outside the cold water tank 31.

[0013] Inside the internal space of the cold water tank 31, a cold water pipe (not shown) having an air inlet and an air outlet is arranged. The cold water pipe forms a coil shape. The water inlet end and the water outlet end of the cold water pipe extend upward and protrude upward from the upper part of the cold water tank 31.

[0014] At the upper end of the cold water pipe, a support member (not shown) in a lattice shape is provided. The support member is fixed to the inner periphery of the inner shell of the cold water tank 31.

[0015] An evaporator (not shown) is supported on the upper end of the support member. Thus, the evaporator is immersed in the cooling water stored in the internal space of the cold water tank 31. The evaporator reduces the temperature of the cooling water during the cooling cycle operation in a state of being immersed in the cooling water of the cold water tank 31.

[0016] The evaporator outlet pipe 60 connected to the evaporator extends along the outside.

[0017] As described above, the evaporator outlet pipe 60 connected to the evaporator exchanges heat with the capillary tube 61 for the remaining cold air after heat exchange with the cooling water to increase the temperature, so that the refrigerant in a liquid state does not flow into the compressor 20.

[0018] In addition, the refrigerant passing through the capillary tube 61 exchanges heat with the evaporator outlet pipe 60 to reduce the temperature, thereby increasing the refrigeration capacity.

[0019] On the other hand, a cover is combined with the upper end of the cold water tank 31. The cover has a heat insulating material cover 32.

[0020] Through the above structure, the cold water tank 31 is combined with the cover. And, the heat insulating part 40 is also combined with the heat insulating material cover 32. A gap is generated between the lower end of the heat insulating material cover 32 and the upper end of the heat insulating part 40.

[0021] Among them, the evaporator outlet pipe of the evaporator penetrates through the cover and protrudes to the outside of the cover. The evaporator outlet pipe of the evaporator is surrounded by a heat insulating material such as polyethylene (PE: Polyethylene) foam 631 for heat insulation.

[0022] Among them, the outer periphery of the evaporator outlet pipe 60 of the evaporator is formed with a structure surrounded by an additional heat insulating material 70. A structure in which the outer periphery of the evaporator outlet pipe 60 and the heat insulating material 70 do not closely adhere to each other uniformly is formed.

[0023] Through this structure, the heat insulation performance for the evaporator outlet pipe 60 may decrease. In addition, the heat insulation between the part of the pipe-shaped heat insulating material 70 through which the evaporator outlet pipe 60 penetrates and the evaporator outlet pipe 60 may become weak.

[0024] Therefore, there is a problem of condensation occurring between the outlet pipe 60 of the evaporator and the heat insulation material 70 in the prior art.

[0025] In addition, it is necessary to form an additional heat insulation structure at the connection part of the outlet pipe 60 of the evaporator and the counterpart such as the connecting pipe of the connected compressor 20. As a result, the thickness of the heat insulation structure increases, and there is a problem that the size of the water purifier increases beyond a constant size.

[0026] In addition, when the size of the water purifier is reduced below a constant size, it is necessary to reduce the installation space of the cooling module 30 below a constant size.

[0027] For this reason, it is necessary to shorten the length of the outlet pipe 60 of the evaporator to below a constant length.

[0028] Among them, a capillary tube 61 is provided inside the outlet pipe 60 of the evaporator. As described above, when the length of the outlet pipe 60 of the evaporator is shortened to below a constant length, the heat exchange length between the outlet pipe 60 of the evaporator and the capillary tube 61 becomes shorter. As a result, the refrigerant flowing at the end of the outlet pipe of the evaporator can be sucked into the compressor 20 in a two-phase (liquid + gas) state. This may reduce the reliability of the compressor.

[0029] Moreover, since the refrigerant at the end of the capillary tube 61 forms a high temperature and dryness (Quality, the ratio of the gas state of the refrigerant) above a constant value, the refrigeration capacity may be reduced.

[0030] Furthermore, the outlet pipe 60 of the evaporator is formed in a structure separated from the cold water tank 31. Thus, when an external vibration is applied to the water purifier, the vibration is transmitted to the outlet pipe 60 of the evaporator. The connection part between the outlet pipe 60 of the evaporator and the evaporator may be damaged. Summary of the Invention

In addition, it can be easily understood that the objects and advantages of the present invention can be achieved by the means and combinations thereof described in the claims.

[0038] Means for Solving the Problem

[0039] To solve the above problems, a technical feature of the water purifier according to an embodiment of the present invention is that a pipe exposed from an evaporator disposed inside a cooling water containing portion to the outside of the cooling water containing portion is buried in a heat insulation portion foamed on the periphery of the cooling water containing portion.

[0040] Specifically, the pipe may be a first pipe formed in a straight shape or a bent shape and disposed along a side wall of the cooling water containing portion.

[0041] In addition, the pipe may have a second pipe connected to an end of the first pipe, and the second pipe may be formed in a straight shape or a bent shape and disposed along a bottom surface of the cooling water containing portion.

[0042] In addition, the first pipe and the second pipe may be formed in a horizontal direction, a vertical direction, or an oblique direction.

[0043] In addition, an end of the pipe may be connected to a connecting pipe, an end of the connecting pipe may be connected to a compressor, and the compressor may be disposed at a position spaced apart from the cooling water containing portion.

[0044] In addition, the pipe may be spaced apart from the periphery of the cooling water containing portion.

[0045] In addition, the pipe may be located in an insertion groove formed on the periphery of the cooling water containing portion, and the pipe may be spaced apart from an inner surface of the insertion groove.

[0046] In addition, a liquid separator buried in the heat insulation portion is connected to the pipe.

[0047] In addition, a vacuum heat insulation portion covering the pipe may be disposed on the periphery of the cooling water containing portion, and the vacuum heat insulation portion may be disposed in a state of being surrounded by the heat insulation portion.

[0048] Advantages of the Invention

[0049] The water purifier of the present invention is miniaturized by burying the pipes of the evaporator and the cooling water accommodating part in one heat insulating part.

[0050] In addition, by foaming the present invention to use one heat insulating part to surround the cooling water accommodating part and the pipes of the evaporator at the same time, the heat insulating performance of the evaporator and the pipes of the evaporator can be uniformly constituted. Thereby, dew condensation on the pipes of the evaporator can be prevented.

[0051] In addition, by burying the pipes of the evaporator in the heat insulating material, the present invention can stably maintain the posture of the pipes of the evaporator that form various shape patterns outside the cooling water accommodating part.

[0052] In addition, the pipes of the evaporator of the present invention can be formed to be longer than a certain length by forming various patterns. Thereby, the heat transfer length between the pipes of the evaporator and the capillary tube of more than a certain level can be ensured.

[0053] In addition, by inserting a part into the periphery of the cooling water accommodating part, the present invention constitutes a multi-layer heat insulation by using a vacuum heat insulating part and a heat insulating part formed by foaming at the periphery of the cooling water accommodating part at the same time.

[0076] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0077] Figure 3 is a perspective view showing a water purifier of the present invention. Figure 4 is a perspective view showing a cooling water accommodating part and a heat insulating part of the present invention.

[0078] Refer to Figure 3 and Figure 4 , the present invention provides a water purifier. The water purifier of the present invention can have a cooling function of cooling raw water to a set cooling temperature.

[0079] The cooling function is constituted by the action of a cooling water accommodating part 200 and a cooling module. The cooling water accommodating part 200 and the cooling module are provided in a main body part 100. The cooling module can be a cooling circulation device. The cooling circulation device has mechanical devices such as an evaporator 500, a compressor 400, and a fan 140.

[0080] Accordingly, the water purifier of the present invention includes a main body 100, a cooling water accommodation part 200 disposed inside the main body 100, an evaporator 500, and a compressor 400.

[0081] The cooling water accommodation part 200 may be a cold water tank for accommodating cooling water. The cooling water accommodation part 200 may be made of a metal such as stainless steel.

[0082] In the main body 100 of the present invention, a first setting area 110 and a second setting area 120 may be formed. The first setting area 110 and the second setting area 120 may be spatially separated.

[0083] The first setting area 110 may be disposed above the second setting area 120.

[0084] The cooling water accommodation part 200 may be disposed in the first setting area 110. The evaporator 500 is disposed in the internal space of the cooling water accommodation part 200.

[0085] The compressor 400 and the fan 500 may be disposed in the second setting area 120. Among them, other mechanical devices constituting the cooling cycle device may be disposed in the second setting area 120. The second setting area 120 is a mechanical room for disposing mechanical devices.

[0086] The second setting area 120 may also be disposed on the side of the first setting area 110. The second setting area 120 may also be disposed at a position separated from the lower part of the first setting area 110. The second setting area 120 may be changed according to the setting position of the compressor 400.

[0087] A grid member 130 is disposed below the first setting area 120, and a fan 140 is disposed on the grid member 130. The compressor 400 is disposed in the second setting area 120 formed on the side of the grid member 130.

[0088] The cooling water accommodation part 200 disposed in the first setting area 110 as described above will be described.

[0089] Figure 5 It is a longitudinal sectional view showing the cooling water accommodation part and the heat insulation part of the present invention.

[0090] Refer to Figure 4 and Figure 5 , the cooling water accommodation part 200 of the present invention forms an internal space for accommodating cooling water. The upper part of the cooling water accommodation part 200 is open. The cooling water accommodation part 200 is a cold water tank formed of metal.

[0091] A cover 201 is coupled to the upper end of the cooling water receiving part 200. The periphery of the cover 201 may be surrounded by a cover heat insulating part 202 formed of an additional heat insulating material.

[0092] The raw water flow part 300 may be disposed in the inner space of the cooling water receiving part 200. The raw water flow part 300 may be a coil-shaped pipe. An inlet 310 may be formed at one end of the raw water flow part 300. Raw water flows into the raw water flow part 300 through the inlet 310. An outlet 320 may be formed at the other end of the raw water flow part 300. The raw water that has undergone heat exchange may flow out to the outside through the outlet 320.

[0093] The raw water flow part 300 is disposed on the bottom surface of the inner space of the water tank body 210. The inlet 310 and the outlet 320 of the raw water flow part 300 may penetrate through the upper end of the cooling water receiving part 200.

[0094] A grid member 230 may be provided in the inner space of the water tank body 210. The grid member 230 may be disposed above the raw water flow part 300. The grid member 230 is formed in a lattice-shaped plate shape. Since the grid member 230 is formed in a lattice shape, the cooling water can flow smoothly. The grid member 230 may be fixed at a constant position on the inner periphery of the water tank body 210. The fixing method may be a structure in which the edge of the grid member 230 is caught by a step (not shown) formed on the inner periphery of the water tank body 210.

[0095] The grid member 230 may partition the inner space of the water tank body 210. The inner space may be partitioned into an upper space and a lower space by the grid member 230.

[0096] That is, the raw water flow part 300 is disposed in the lower space.

[0097] Evaporator 500

[0098] The evaporator 500 of the present invention is disposed in the upper space described above. The evaporator may be placed and supported on the upper end of the grid member 230.

[0099] The evaporator 500 is formed in a coil shape and constitutes a pipe shape for the refrigerant to flow through.

[0100] The evaporator 500 has a connecting pipe 501. The connecting pipe 501 is connected to the evaporator 500, and its end is located at a through hole 211 formed at the upper end edge of the water tank body 210.

[0101] At the other end of the connecting pipe 501, a pipe 510 exposed to the outside of the cooling water accommodating portion 200 is connected. The overall length of the pipe 510 can be configured to be a specified length during design.

[0102] Among them, the pipe 510 can be composed of a first pipe 511 and a second pipe 512. The first pipe 511 and the second pipe 512 are formed from one pipe.

[0103] One end of the first pipe 511 can be integrally formed and connected to the other end of the connecting pipe 501. The first pipe 511 can form a preset shape pattern and be arranged along the periphery of the water tank body 210. In fact, the first pipe 511 can be buried inside a heat insulation portion 600 formed by foaming described later.

[0104] One end of the second pipe 512 is integrally formed and connected to the other end of the first pipe 511. In fact, the second pipe 512 is a pipe that extends to the outside of the heat insulation portion 600 and extends to the above-mentioned second installation area 120 (refer to Figure 3 ). The other end of the second pipe 512 can be connected to the above-mentioned compressor 400. The connection method can be a connection method such as welding.

[0105] Among them, a through hole 211 can be formed at the upper end edge of the water tank body 210. The pipe 510 can be led out of the water tank body 210 through the through hole 211. The pipe 510 can be bent with a curvature at the through hole 211.

[0106] The periphery of the water tank body 210 can include a side wall and a bottom surface. The pipe 510 of the present invention can be arranged adjacent to the side wall of the water tank body 210.

[0107] The pipe 510 of the evaporator 500 can be formed along the side wall of the water tank body 210. Of course, the shape of the pipe 510 can form various patterns. Later, various shape patterns of the pipe will be described.

[0108] The pipe 510 of the evaporator 500 according to an example of the present invention can form a set shape downward near the side wall of the water tank body 210. Among them, the pipe 510 can form a constant interval with the side wall of the water tank body 210. A heat insulation material can be foamed in the space formed by the interval to form a heat insulation portion 600 described later. Thus, the first pipe 501 of the present invention can be filled inside the heat insulation portion 600.

[0109] The heat insulation portion 600 of the present invention will be described.

[0110] In the present invention, the heat insulation part 600 is formed by foaming. The heat insulation part 600 can be formed by foaming a heat insulation material such as PU.

[0111] The heat insulation part 600 is formed to surround the side wall and the bottom surface of the water tank body 210. The thickness of the heat insulation part 600 can form a uniform thickness from the periphery of the water tank body 210.

[0112] The first pipe 511 connected to the end of the connection pipe of the evaporator 500 can be buried inside the heat insulation part 600. The end of the second pipe 512 connected to the other end of the first pipe 511 can penetrate through the lower part of the heat insulation part 600 and extend to the outside.

[0113] In addition, the bent part of the pipe 510 passing through the through hole 211 formed in the water tank body 210 can be surrounded by the foamed heat insulation part 600.

[0114] The heat insulation part 600 of the present invention can be formed of a single foaming material. Thus, the heat insulation part 600 can simultaneously insulate the first pipe 511 of the evaporator 500 and the periphery of the water tank body 210. The first pipe 511 other than the second pipe 512 which is the part led out from the heat insulation part 600 can achieve uniform heat insulation.

[0115] Thus, the first pipe 511 can be buried in the foamed heat insulation part 600.

[0116] The heat insulation part 600 can be cured after a constant time after foaming. Thus, the pipe 510 can be fixed in a posture capable of maintaining a set straight or bent shape. Among them, the shape of the first pipe 511 is not limited to a straight or bent shape. More precisely, the heat insulation part 600 can support the pipe 511 buried inside the heat insulation part 600.

[0117] In addition, the heat insulation part 600 of the present invention can have constant elasticity. Thus, when an impact is applied to the pipe 510 from the outside, the heat insulation part 600 can easily absorb the impact. And the heat insulation part 600 can also keep the first pipe 511 in its original shape pattern.

[0118] Figure 3 and Figure 4 An example showing the first pipe 511 of the present invention formed in a straight shape is shown.

[0119] The first pipe 511 is exposed to the outside of the water tank body 210.

[0120] One end of the first pipe 511 is connected to the end of the connecting pipe 501 located in the through hole 211, and the first pipe 511 extends linearly downward along the side wall of the water tank body 210. Among them, the first pipe 511 is spaced from the side wall of the water tank body 210 by a constant interval. And the first pipe 511 can form a linear shape, but is formed in a vertical direction or an oblique direction with respect to the top surface of the water tank body 210 as a reference.

[0121] In this state, if the heat insulating material is foamed, the periphery of the cooling water accommodating part 200 and the first pipe 511 can be buried inside the foamed heat insulating part 600. Among them, since the first pipe 511 is spaced from the side wall of the water tank body 210, the heat insulating part 600 can form a structure surrounding the outer periphery of the first pipe 511.

[0122] In the above case, an example in which the pipe 511 of the evaporator 500 forms a linear pattern near the side wall of the water tank body 210 is taken as a representative example for description.

[0123] Then, with reference to Figures 6 to 8 , an example in which the first pipe 511' of the present invention forms a bent shape along the side wall of the water tank body 210 will be described.

[0124] Figure 6 It is a perspective view showing an example in which the bent pipe of the present invention is buried in the heat insulating part foamed at the periphery of the used cooling water accommodating part. Figure 7 It is a longitudinal sectional view showing an example in which the bent pipe of the present invention is buried in the heat insulating part foamed at the periphery of the used cooling water accommodating part. Figure 8 It is a transverse sectional view showing an example in which the bent pipe of the present invention is buried in the heat insulating part foamed at the periphery of the used cooling water accommodating part.

[0125] The first pipe 511' connected to the evaporator 500 of the present invention can form a bent shape. And the second pipe 512 can have various degrees of freedom according to the arrangement position of the compressor 400 (refer to Figure 3 ).

[0126] With reference to Figure 6 and Figure 7 , a through hole 211 can be formed at the upper end edge of the water tank body 210 of the present invention. The first pipe 511' can be led out of the water tank body 210 through the through hole 211. The first pipe 511' can be bent with a curvature in the through hole 211.

[0127] The first pipe 511 can be arranged along the side wall of the water tank body and can form a shape that bends up and down repeatedly.

[0128] Among them, the first pipe 511' can be formed by a first bent pipe 511'a, a second bent pipe 511'b, a third bent pipe 511'c, a fourth bent pipe 511'd, and a fifth bent pipe 511'e.

[0129] The first bent pipe 511'a bends downward from the end of the connecting pipe 501 and extends in the vertical direction.

[0130] The second bent pipe 511'b has a constant length and bends horizontally from the lower end of the first bent pipe 511'a.

[0131] The third bent pipe 511'c has a constant length and bends upward from the end of the second bent pipe 511'b and extends in the vertical direction.

[0132] The fourth bent pipe 511'd has a constant length and bends horizontally from the upper end of the third bent pipe 511'c.

[0133] The fifth bent pipe 511'e has a constant length and bends downward from the end of the fourth bent pipe 511'd and extends in the vertical direction.

[0134] Moreover, at the lower end of the fifth bent pipe 511'e, it can be integrally connected to the end of the second pipe 512.

[0135] As described above, the first pipe 511' formed by the first bent pipe 511'a, the second bent pipe 511'b, the third bent pipe 511'c, the fourth bent pipe 511'd, and the fifth bent pipe 511'e can be buried inside the foamed heat insulation part.

[0136] Since the present invention can variably design the number of bends of the first pipe 511', the heat exchange time of the refrigerant flowing through the first pipe 511' can be increased to a constant time.

[0137] The first pipe 511' of the present invention shows a shape that repeatedly bends in the vertical and horizontal directions along the side wall of the water tank body 210.

[0138] Among them, the first pipe 511' of the present invention forms a repeatedly bent shape. As described above, it is not limited to the vertical and horizontal shapes.

[0139] That is, although not shown, the first pipe 511' can also form a shape in which the first bent pipe 511'a, the second bent pipe 511'b, the third bent pipe 511'c, the fourth bent pipe 511'd, and the fifth bent pipe 511'e are inclinedly arranged in the oblique direction.

[0140] In addition, the first pipe 511' may also form a repeatedly bent arc shape.

[0141] On the other hand, the periphery of the water tank body 210 may include a side wall and a bottom surface. The first pipe 511' that forms a pattern of a repeatedly bent shape in the present invention may be disposed adjacent to the side wall of the water tank body 210.

[0142] Moreover, the first pipe 511' may form a constant interval from the side wall of the water tank body 210. The space forming the interval may be filled with a heat insulating material that constitutes the heat insulating part 600 described later by foaming.

[0143] The heat insulating part 600 may be formed by foaming using a heat insulating material such as PU.

[0144] The heat insulating part 600 may be formed to surround the side wall and the bottom surface of the water tank body 210. The thickness of the heat insulating part 600 may form a uniform thickness from the periphery of the water tank body 210.

[0145] The first pipe 511' that forms a pattern of a repeatedly bent shape of the evaporator 500 may be buried inside the heat insulating part 600 formed by foaming. The end of the first pipe 511' may be located offset to the side part of the water tank body 210. And at the corresponding position, the lower end of the fifth bent pipe 511'e of the first pipe 511' may be connected to the second pipe 512, and the second pipe 512 may penetrate through the lower part of the heat insulating part 600 and extend to the outside.

[0146] In addition, the bent part of the first pipe 511' passing through the through hole 211 formed in the water tank body 210 may be surrounded by the heat insulating part 600.

[0147] The heat insulating part 600 of the present invention may be formed of one foaming material. Thus, the heat insulating part 600 can simultaneously insulate the first pipe 511' that forms a pattern of a repeatedly bent shape of the evaporator 500 and the periphery of the water tank body 210. The pipes 511 other than the part led out from the heat insulating part 600 may form uniform heat insulation.

[0148] The outer surface of the first pipe 511' may be buried in the foamed heat insulating part 600. The heat insulating part 600 may be cured after a constant time after foaming. Thus, the first pipe 511' can be fixed to constantly maintain the repeatedly bent posture. That is, the heat insulating part 60 can support the first pipe 511 embedded inside the heat insulating part 600.

[0149] In addition, the heat insulation part 600 of the present invention may also have a constant elasticity. Thus, when an impact is applied to the first pipe 511' from the outside, the heat insulation part 600 can easily absorb the impact. Also, the heat insulation part 600 can maintain the pattern of the repeatedly bent shape of the first pipe 511'.

[0150] The first pipe 511' forms a pattern of a repeatedly bent shape, with intervals formed between them, constituting a plurality of bent parts. The plurality of bent parts may be subjected to local forces due to external impacts.

[0151] The outer peripheral surfaces of the plurality of bent parts are embedded inside the heat insulation part 600 to form a uniform contact surface with the heat insulation part 600. Therefore, the heat insulation loss rate in the plurality of bent parts can be reduced to below a constant value.

[0152] Furthermore, the impact applied to the plurality of bent parts can be easily absorbed by the heat insulation part 600 surrounding the plurality of bent parts.

[0153] In addition, as the first pipe 511' of the evaporator 500 forms a pattern of a repeatedly bent shape, the length of the first pipe 511' of the evaporator 500 can be formed to be longer than a constant value. Thus, the heat exchange length with a capillary tube (not shown) disposed inside the first pipe 511' of the evaporator 500 can be ensured to be longer than a constant length. Therefore, the refrigerant at the end of the first pipe 511' of the evaporator 500, which is the end of the evaporator outlet pipe, will not be supplied to the compressor 400 in a two-phase (liquid + gas) state (refer to Figure 3 )

[0154] In addition, since the first pipe 511' of the present invention forms a pattern of a repeatedly bent shape near the side wall of the water tank body, the interval of the overall pipe 510 of the evaporator 500 connected to the compressor 400 can be reduced to below a constant value. This can reduce the overall size of the water purifier of the present invention to below a constant size.

[0155] That is, the present invention uses the bent first pipe 511', embeds it in the heat insulation part 600, so as to not only fully ensure a heat exchange length longer than a constant value, but also increase the degree of freedom of the second pipe 512, reduce the distance between the evaporator 500 and the compressor 400, thereby effectively reducing the overall size of the water purifier.

[0156] Figure 9 It is a perspective view showing an example in which the present invention is embedded in a foamed heat insulation part in a state where the first pipe is disposed along the side wall and bottom surface of the cooling water accommodation part.

[0157] Refer to Figure 9, the first pipe 511″ of the evaporator 500 of the present invention can form two or more patterns. The first pipe 511″ can be disposed adjacent to the side wall and the bottom surface of the water tank body 210.

[0158] The first pipe 511″ can be formed by a first side wall pipe 511″a and a first bottom surface pipe 511″b.

[0159] The first side wall pipe 511″a is disposed along the side wall of the water tank body 210 and is formed in a straight line shape. The upper end of the first side wall pipe 511″a is connected to the end of the connection pipe 501 disposed in the through hole 211 formed at the upper end edge of the water tank body 210. The first side wall pipe 511″a extends vertically downward from the upper end of the water tank body 210.

[0160] The first bottom surface pipe 511″b is disposed along the bottom surface of the water tank body 210.

[0161] One end of the first bottom surface pipe 511″b is connected to the lower end of the first side wall pipe 511″a and is bent along the bottom surface of the water tank body 210.

[0162] The first bottom surface pipe 511″b can be bent into a U shape. That is, the first bottom surface pipe 511″b is formed by a 1-1 bottom surface pipe 511″b1 that forms a straight line shape, a 1-2 bottom surface pipe 511″b2 that is bent from the end of the 1-1 bottom surface pipe 511″b1 and forms a straight line shape, and a 1-3 bottom surface pipe 511″b3 that is bent from the end of the 1-2 bottom surface pipe 511″b2 and forms a straight line shape.

[0163] And, the end of the 1-3 bottom surface pipe 511″b3 is connected to the second pipe 512. Among them, the second pipe 512 is bent downward from the end of the 1-3 bottom surface pipe 511″b3.

[0164] As described above, the first pipe 511″ of the present invention can form a constant pattern along the side wall and the bottom surface of the water tank body 210.

[0165] As described above, the first side wall pipe 511″a can be configured in a straight line shape or can be configured in a repeatedly bent shape. In addition, the first side wall pipe 511″a can be formed in a vertical direction or can be formed in an oblique direction.

[0166] In addition, as described above, the first bottom surface pipe 511″b can be bent into a U shape, or can be formed in a straight line shape or a repeatedly bent shape. In addition, the first bottom surface pipe 511″b can also be formed in an oblique direction near the bottom surface of the water tank body.

[0167] Among them, the first pipe 511″ can be spaced apart from the side wall and the bottom surface of the water tank body 210 by a constant interval.

[0168] In this state, an insulation part 600 can be formed by a foamed heat insulation material between the periphery of the cooling water accommodation part 200 and the first pipe 511″. Thus, the cooling water accommodation part 200 and the first pipe 511′ can be buried inside the foamed insulation part 600.

[0169] Figure 10 It is a perspective view showing another example of the present invention buried in the foamed insulation part in a state where the first pipe is arranged along the side wall and the bottom surface of the cooling water accommodation part.

[0170] Refer to Figure 10 , the first pipe 520 of the evaporator 500 of the present invention can form two or more patterns. The first pipe 520 can be arranged adjacent to the side wall and the bottom surface of the water tank body 210.

[0171] The first pipe 520 can be formed by a first side wall pipe 521 and a first bottom surface pipe 522.

[0172] The first side wall pipe 521 is arranged along the side wall of the water tank body 210 and is formed in a straight line shape.

[0173] The upper end of the first side wall pipe 521 is connected to the end of the connecting pipe 501.

[0174] The first side wall pipe 521 can have a shape that repeatedly bends up and down along the side wall of the water tank body 210. The repeatedly bending shape can be the same as that of the first pipe 511′ of the above Figure 6 .

[0175] Of course, the first side wall pipe 521 can also form a U shape or a straight line shape pattern.

[0176] And, the first bottom surface pipe 522 is arranged along the bottom surface of the water tank body 210.

[0177] The first bottom surface pipe 522 can be formed in a bent shape in a U shape.

[0178] The shape of the first bottom surface pipe 522 can be the same as that of the first bottom surface pipe 511″b shown in Figure 9 . That is, the first bottom surface pipe 522 is formed by a 1-1 bottom surface pipe 522a that forms a straight line shape, a 1-2 bottom surface pipe 522b that bends from the end of the 1-1 bottom surface pipe 522a and forms a straight line shape, and a 1-3 bottom surface pipe 522c that bends from the end of the 1-2 bottom surface pipe 522b and forms a straight line shape.

[0179] Of course, the first bottom pipe 522 may also be formed into a pattern with a plurality of bent shapes or a straight shape.

[0180] In addition, the first side pipe 521 and the first bottom pipe 522 may also be formed in an inclined direction near the periphery of the water tank body 210.

[0181] Among them, the first pipe 520 may be spaced apart from the side wall and the bottom surface of the water tank body 210 by a constant interval.

[0182] In this state, a heat insulation part 600 may be formed between the periphery of the cooling water accommodating part 200 and the first pipe 520 by a foamed heat insulation material. Thus, the cooling water accommodating part 200 and the first pipe 520 may be buried inside the foamed heat insulation part 600.

[0183] And, the end of the first bottom pipe 522 protrudes from the heat insulation part 600 and is connected to the second pipe 512 extending along the lower part of the water tank body 210.

[0184] The end of the second pipe 512 may be configured to extend laterally from the heat insulation part 600. The degree of freedom of the second pipe 512 may be variably set according to the arrangement position of the connected object, the compressor 400 (refer to Figure 3 ).

[0185] As Figure 9 and Figure 10 shown, the heat insulation part 600 of the present invention may be formed by foaming. The heat insulation part 600 may be formed by foaming using a heat insulation material such as PU.

[0186] The heat insulation part 600 may be formed to surround the side wall and the bottom surface of the water tank body 210, and the thickness of the heat insulation part 600 may form a uniform thickness from the periphery of the water tank body 210.

[0187] The first pipes 511″, 520 of the evaporator 500 may be adjacent to the side wall and the bottom surface of the water tank body 210 and form different pattern shapes from each other. That is, the first pipes 511″, 520 may be adjacent to the side wall and the bottom surface of the water tank body 210 and ensure a heat transfer length of more than a predetermined constant.

[0188] As described above, the first pipes 511″, 520 of the evaporator forming various shaped patterns may be buried inside the heat insulation part 600. The ends of the first pipes 511″, 520 may extend to the outside through the lower side part or the lower part of the heat insulation part 600.

[0189] In addition, the bent part of the through hole 211 formed in the water tank body 210 through which the first pipe 520 passes may be surrounded by the heat insulation part 600.

[0190] The heat insulation part 600 of the present invention can be formed by using a foaming material. Thus, the heat insulation part 600 can simultaneously insulate the first pipes 511″, 520 of the evaporator 500 and the water tank body 210. The first pipes 511″, 520 other than the parts led out from the heat insulation part 600 can form uniform heat insulation.

[0191] The outer surfaces of the first pipes 511″, 520 can be embedded in the foamed heat insulation part 600. The heat insulation part 600 can be cured after a constant time after foaming. Thus, the pipes 511″, 520 can be fixed in a state adjacent to the side wall and the bottom surface of the water tank body 210 to maintain various pattern shapes. The heat insulation part 600 can support the first pipes 511″, 520 embedded inside the heat insulation part 600.

[0192] In addition, the heat insulation part 600 of the present invention can have constant elasticity. Through this, when an impact is applied to the first pipes 511″, 520 from the outside, the heat insulation part 600 can easily absorb the impact.

[0193] As Figure 9 and Figure 10 shown, the first pipes 511″, 520 of the evaporator 500 can form different pattern shapes from each other in a state adjacent to the side wall and the bottom surface of the water tank body 210. In particular, the first pipes 511″, 520 adjacent to the bottom surface of the water tank body 210 may bend downward under the action of their own loads. That is, the pattern shapes of the first pipes 511″, 520 may be deformed.

[0194] Here, the heat insulation part 600 of the present invention can be foamed to surround the side wall and the bottom surface of the water tank body 210 and embed the first pipes 511″, 520. Thus, the heat insulation part 600 of the present invention can always maintain the original postures of the set straight shape, the shape of a plurality of bends, and the U-shaped pattern of the first pipes 511″, 520.

[0195] The first pipes 511″, 520 are bent in a U shape or form a zigzag pattern, so as to form a gap between each other and form a plurality of bent parts. Here, the plurality of bent parts are subjected to local forces under the action of external impacts.

[0196] The outer peripheral surfaces of the plurality of bent parts are embedded inside the heat insulation part 600 and form a uniform contact surface. Therefore, heat loss of the plurality of bent parts can be prevented.

[0197] Furthermore, the impact applied to the plurality of bent parts can be easily absorbed by the heat insulation part 600 surrounding the plurality of bent parts.

[0198] In addition, the first pipes 511″ and 520 of the evaporator 500 of the present invention form at least one combined pattern of a linear shape, a plurality of bent shapes, and a U shape, so that the pipe length of the evaporator 500 can be formed longer than a certain constant value.

[0199] Thereby, a heat exchange length longer than a certain constant value with a capillary tube (not shown) disposed in the first pipes 511″ and 520 of the evaporator 500 can be ensured. Therefore, refrigerant is not supplied to the compressor 400 (refer to Figure 3 ) in a two-phase (liquid + gas) state from the ends of the first pipes 511″ and 520 at the evaporator outlet pipe end of the evaporator 500.

[0200] In addition, the first pipes 511″ and 520 of the evaporator 500 of the present invention can form various pattern shapes and be buried inside a foamed heat insulation part 600 near the periphery of the water tank body 210. Thereby, the first pipes 511″ and 520 can ensure a heat exchange length longer than a certain constant value. Thereby, the first pipes 511″ and 520 of the evaporator 500 can ensure a heat exchange length longer than a certain constant value. In addition, the distance between the compressor 400 and the ends of the first pipes 511″ and 520 of the evaporator 500 can be reduced to less than a certain constant value. This can effectively reduce the overall size of the water purifier of the present invention.

[0201] Figure 11 FIG. is a perspective view showing a state where the liquid separator of the present invention is provided on the first pipe and buried in the foamed heat insulation part. Figure 12 FIG. is a longitudinal sectional view showing a state where the liquid separator of the present invention is provided on the first pipe and buried in the foamed heat insulation part. Figure 13 FIG. is a transverse sectional view showing a state where the liquid separator of the present invention is provided on the first pipe and buried in the foamed heat insulation part.

[0202] Refer to Figures 11 to 13 , a through hole 211 may be formed at the upper edge of the water tank body 210 of the present invention. The first pipe 511 of the evaporator 500 of the present invention can be led out to the outside of the water tank body 210 through the through hole 211. The first pipe 210 can be bent with a curvature at the through hole 211.

[0203] The first pipe 511 of the present invention can be disposed adjacent to the side wall of the water tank body. The first pipe 511 of the evaporator 500 can form a pattern of a linear shape and be formed along the side wall of the water tank body 210.

[0204] And, a liquid separator 700 is provided at a constant position of the first pipe 511 near the side wall of the water tank body 210. The liquid separator 700 of the present invention can be disposed at Figure 3The first setting area 110. That is, the liquid separator 700 can be excluded from the second setting area 120. Thus, the second setting area 120 can be reduced by an area equivalent to the setting area of the liquid separator 700.

[0205] The liquid separator 700 can be disposed between the compressor and the evaporator 500. The liquid separator 700 can separate the liquid refrigerant from the refrigerant flowing in the first pipe 511 of the evaporator 500 and supply only the gas to the compressor. Thus, the liquid separator 700 can prevent the compressor from performing liquid compression.

[0206] The first pipe 511 of the evaporator 500 of the present invention can be formed in a straight line shape downward from near the side wall of the water tank body 210. Among them, the first pipe 511 can be spaced apart from the side wall of the water tank body 210 by a constant interval. The space formed by the interval can be foamed with a heat insulating material constituting a heat insulating portion 600 described later.

[0207] Among them, the heat insulating portion 600 of the present invention can be formed by foaming. The heat insulating portion 600 can be formed by foaming using a heat insulating material such as PU.

[0208] The heat insulating portion 600 is formed to surround the side wall and the bottom surface of the water tank body 210. The thickness of the heat insulating portion 600 can form a uniform thickness from the periphery of the water tank body 210.

[0209] In addition, the liquid separator 700 can be buried inside the heat insulating portion 600 in a state of being disposed on the pipe 511 of the evaporator 500. Thus, a space corresponding to the setting area of the liquid separator 700 excluded from the second setting area 120 of the main body portion 100 above can be ensured.

[0210] Furthermore, under the action of the heat insulating portion 600, heat loss at the connection portions of both ends of the liquid separator 700 and the first pipe 511 can be effectively prevented. Under the action of the heat insulating portion 600, the connection portions of both ends of the liquid separator 700 and the first pipe 511 can be easily supported.

[0211] As described above, an example in which the liquid separator is disposed on the first pipe 511 having a pattern with a plurality of bent shapes is described as a representative.

[0212] However, the liquid separator 700 of the present invention can also be disposed on the first pipe having other pattern shapes such as a straight line shape and a plurality of bent shapes. The above example can be applied to the first pipe.

[0213] In addition, the liquid separator 700 of the present invention can also be disposed at other positions including the heat insulating portion 600 foamed on the periphery of the water tank body 210.

[0214] On the other hand, the heat insulation part of the present invention can be provided simultaneously with the vacuum heat insulation part having other heat insulation coefficients.

[0215] Figure 14 It is a transverse cross-sectional view showing an example of the simultaneous use of the heat insulation part and the vacuum heat insulation part of the present invention.

[0216] Refer to Figure 14 , the vacuum heat insulation part 610 of the present invention is a vacuum heat insulation panel. The vacuum heat insulation part 610 can be formed in a plate shape.

[0217] The vacuum heat insulation part 610 can be arranged near the side wall of the water tank body 210.

[0218] The following first pipe is described by taking the first pipe with the reference numeral 511 as a representative example.

[0219] The first pipe 511 of the evaporator 500 can be arranged at a distance from the side wall of the water tank body 210. Similar to the above example, the first pipe 511 of the evaporator 500 can form a zigzag pattern. Of course, the first pipe 511 can also be formed in a straight line pattern or a bent pattern shape.

[0220] One side surface of the vacuum heat insulation part 610 can be arranged to closely adhere to the outer surface of the first pipe 511.

[0221] Moreover, the heat insulation part 600 of the present invention can be formed by foaming to surround the periphery of the water tank body 210 and the vacuum heat insulation part 610.

[0222] Thus, the vacuum heat insulation part 610 of the present invention can be buried in the inner space of the heat insulation part 600.

[0223] As described above, the present invention can arrange the vacuum heat insulation part 610 on the side wall of the water tank body 210. And the heat insulation part 600 can be formed by a foamed heat insulation material to surround the vacuum heat insulation part 610 and the periphery of the water tank body 210. Thus, the pipe 510 of the evaporator 500 can use the vacuum heat insulation part 610 and the heat insulation part 600 to form multiple heat insulation.

[0224] Figure 15 It is a transverse cross-sectional view showing another example of the simultaneous use of the heat insulation part and the vacuum heat insulation part of the present invention.

[0225] Refer to Figure 15 , an insertion groove 212 can be formed on the side wall of the water tank body 210 of the present invention. The insertion groove 212 can be formed corresponding to the pattern shape of the first pipe 511 of the evaporator 500.

[0226] The first pipe 511 of the evaporator 500 may form an annular cross-section. The insertion groove 212 may be formed in a shape for a part of the first pipe 511 of the evaporator 500 to be inserted.

[0227] The outer surface of the first pipe 511 may be spaced from the inner circumferential surface of the insertion groove 212 by a constant distance. When a heat insulating material is foamed in the spaced space, the heat insulating material may fill the spaced space.

[0228] Moreover, the plate-shaped vacuum heat insulating part 610 may be disposed near the side wall of the water tank body 210.

[0229] The first pipe 511 of the evaporator 500 may be spaced from the side wall of the water tank body 210.

[0230] Similar to the above example, the first pipe 511 of the evaporator 500 may form a plurality of bent-shaped patterns. Of course, the first pipe 511 may also form various pattern shapes.

[0231] One side surface of the vacuum heat insulating part 610 may be disposed in close contact with the outer surface of the first pipe 511 of the evaporator 500.

[0232] Moreover, the heat insulating part 600 of the present invention may be formed by foaming to surround the periphery of the water tank body 210 and the vacuum heat insulating part 610. Thus, the vacuum heat insulating part 610 of the present invention may be buried in the inner space of the heat insulating part 600.

[0233] As described above, the present invention reduces the interval at which the first pipe 511 of the evaporator 500 protrudes from the side wall of the water tank body 210 to below a constant value. As described above, when the vacuum heat insulating part 610 and the heat insulating part 600 are used simultaneously, compared with Figure 14 the case of, it is possible to reduce the heat insulating thickness on the side where the vacuum heat insulating part 610 is disposed to below a constant value.

[0234] On the other hand, as described above, the present invention may bury the periphery of the cooling water accommodating part and the first pipe in the interior of the heat insulating part formed by foaming.

[0235] Referring to the above drawings, the process of burying the pipe and the periphery of the cooling water accommodating part will be described. The first pipe will be described by taking the first pipe with the above reference numeral 511 as a representative example. In addition, the reference numerals of the components included in the following description refer to the above drawings.

[0236] In the present invention, when using a heat insulating material to form the heat insulating part 600, an outer member (not shown) that supports the inner side surface of the inner space of the cooling water accommodating part 200 and surrounds the periphery of the cooling water accommodating part 200 is used.

[0237] At this time, a foaming space may be formed between the periphery of the cooling water accommodating part 200 and the outer member. Further, a heat insulating part 700 may be formed by injecting a heat insulating material into the foaming space by using a heat insulating material injection device (not shown) and causing the material to foam.

[0238] At this time, in the present invention, a plurality of support plates (not shown) may be used to support the inner side surface of the inner space of the cooling water accommodating part 200 to prevent shape deformation caused by pressure during foaming.

[0239] Among them, referring to Figure 4 , the grid member 230 of the present invention is formed in a quadrilateral plate shape and in a lattice shape. Further, grooves 231 for inserting the support plates are formed at the four peripheries of the grid member. Further, a flow path guiding member 232 is coupled to each of the grooves 231, and the flow path guiding member 232 is inserted and coupled to the groove 231 after removing the plurality of support plates. The flow path guiding member 232 is formed in a lattice shape.

[0240] In the foaming process, the above-described flow path guiding member 232 that can be coupled to the groove 231 of the grid member 230 is in a disassembled state.

[0241] Accordingly, the grooves 231 formed at the four peripheries of the grid member 230 disposed in the inner space of the cooling water accommodating part 200 may be in an open state.

[0242] Further, a raw water flowing part 300 is disposed below the grid member 230, and an evaporator 500 is disposed above. In addition, the pipe 510 of the evaporator 500 may be in a state of extending to the outside of the cooling water accommodating part 200.

[0243] Therefore, in the inner space of the cooling water accommodating part before the heat insulating material is foamed, the grid member 230, the raw water flowing part 300, and the evaporator 500 may be in a state of being arranged and assembled.

[0244] Further, four support plates are inserted into the grooves 231. The four support plates support the inner wall of the inner space of the water tank body 210.

[0245] Then, a heat insulating material may be injected into the foaming space formed between the above-described outer member (not shown) and the periphery of the cooling water accommodating part 200.

[0246] After the foaming is formed, the outer member may be removed.
