[0039]
On the upper surface of the container body 22, two upper surface plates 32 and 34 are provided that open and close to the left and right respectively by a hinge structure. In the state where the two upper surface plates 32 and 34 are closed, the liquid storage bag 24 is protected from falling objects and the like, so that the tearing of the liquid storage bag 24 can be prevented.
[0040]
When the two upper surface plates 32 and 34 are opened and the lever mechanism 28 is further removed from the liquid storage bag 24, the liquid storage bag 24 can be taken out from the upper surface opening of the container body 22. Therefore, when injecting the liquid W, the liquid storage bag 24 may be taken out from the container body 22 as necessary.
[0041]
The material of the main components in the liquid container 20 excluding the bottom heat transfer plate 36 is formed of a resin such as polypropylene, for example. By molding with resin, mass production can be performed at low cost, and a structure that is lightweight and excellent in toughness can be obtained.
[0042]
As shown in FIG. 3, the container main body 22 includes a copper bottom heat transfer plate 36 at the center bottom plate, a base 38 having a height of H1, a rectangular shape that is located at the top, and has a height of H2. The frame 40, the first divided side plates 42a and 42b and the second divided side plates 44a and 44b, which connect the base 38 and the frame 40 with two opposite sides, respectively, and the two opposite sides of the frame 40 are respectively axised. A pair of jumping plates 46 and 48 are supported. A grip 41 is provided on the side surface of the frame body 40.
[0043]
The first divided side plates 42a and 42b have a substantially rectangular shape, and one side of the first divided side plate 42a is pivotally supported on the lower side of the frame 40 so as to be swingable. Further, one side of the first divided side plate 42b is pivotally supported by one side above the base 38 so as to be swingable. The other side of each of the first divided side plates 42a and 42b is pivotally supported by an intermediate portion between the base 38 and the frame body 40 so as to be swingable.
[0044]
The second divided side plates 44a and 44b are also pivotally supported on the base 38 and the frame body 40 by the same structure as the first divided side plates 42a and 42b.
[0045]
The lower end of the jumping plate 46 has a gentle V-shape along the end of the inclined surface 36a (see FIG. 5A) of the bottom heat transfer plate 36, and a semicircular cut 46a at the center of the lower end. (Pouring mechanism attaching portion) is provided (see FIG. 4A).
[0046]
One side surface 38 a of the base 38 positioned below the jumping plate 46 has a gentle, substantially V-shaped upper end along the end of the bottom heat transfer plate 36, and the V-shaped shape of the jumping plate 46. Consistent with. Further, a semicircular cut 38b (pouring mechanism mounting portion) is provided at the center of the upper end, and the cut 38b and the cut 46a form a circular hole (see FIG. 4A).
[0047]
As shown to FIG. 4A, the rectangular parallelepiped protrusion parts 49 and 50 for attaching the lever mechanism part 28 are provided in the left and right of the notch | incision 46a, and the surface where each protrusion part 49 and 50 opposes, Grooves 52 and 54 having a width L are provided in the vertical direction. The protruding portions 49 and 50 are provided with a slight gap from the lower end of the jumping plate 46 so that the protruding portions 49 and 50 do not come into contact with the bottom heat transfer plate 36 at the time of jumping up.
[0048]
The protrusions 49 and 50 may be provided on one side surface 38 a of the base 38. Moreover, as shown to FIG. 4B, you may provide in both the jump board 46 and the one side 38a.
[0049]
As shown in FIG. 5A, the bottom heat transfer plate 36 includes a gentle substantially V-shaped slope 36a that is bilaterally symmetric with respect to the central axis C1, and a semi-conical groove 36b that extends along the central axis C1. Have The groove portion 36b is a large arc-shaped groove in which one liquid collecting portion 36c is deeper than the other groove end portion 36d. In other words, the liquid collecting portion 36c is set to a shape that is the lowest and increases from the liquid collecting portion 36c toward the other peripheral edge.
[0050]
The bottom heat transfer plate 36 has a larger surface area than the simple V-shaped plate due to the presence of the groove 36b. In order to increase the surface area in consideration of heat transfer, for example, as shown in FIG. 5B, a plurality of groove portions 37a or convex portions 37b may be provided.
[0051]
Since the height H3 of the bottom heat transfer plate 36 is set to be smaller than the height H1 of the base 38, the groove 36b is in contact with the floor surface when the liquid storage container 20 is placed on a flat floor surface. The bottom heat transfer plate 36 is protected.
[0052]
The bottom heat transfer plate 36 is made of copper (including a copper alloy) as a material, is excellent in thermal conductivity and workability, and is inexpensive. The material of the bottom heat transfer plate 36 may be a metal such as aluminum (including an aluminum alloy) or stainless steel other than copper. Aluminum is excellent in thermal conductivity and workability, is lightweight and inexpensive. Stainless steel is excellent in thermal conductivity, corrosion resistance and strength. Therefore, an appropriate material may be selected from these metal materials depending on the use environment and design conditions.
[0053]
As shown in FIG. 6, the substantially cylindrical extraction mechanism 26 is welded or bonded to the liquid storage bag 24 at a flange 56 provided at one end. In the central portion of the flange 56, the liquid storage bag 24 is open, and the liquid storage bag 24 and the inside of the dispensing mechanism portion 26 communicate with each other. An elastic plug 58 is provided at the other end of the dispensing mechanism 26 to keep the dispensing mechanism 26 liquid-tight.
[0054]
The plug 58 is provided with a flat and relatively small small protrusion (a part of the plug) 60. When the small protrusion 60 is pushed by an external force, the plug 58 is elastically deformed and the seal portion 62 is formed. (See FIG. 8) opens. Thereby, since the inside of the pouring mechanism part 26 and the liquid storage bag 24 communicates with the outside, the liquid W can be poured out or injected from the pouring outlet 63 communicating with the seal part 62. Further, when the force applied to the small protrusion 60 is released, the plug 58 returns to the original shape again, and the inside of the dispensing mechanism portion 26 and the liquid storage bag 24 is kept liquid-tight.
[0055]
Around the substantially central height of the dispensing mechanism 26, three mounting annular grooves, that is, a first annular groove 64a, a second annular groove 64b, and a third annular groove 64c are provided in this order from the stopper 58 side. ing. The width of the first annular groove 64a is L.
[0056]
As shown in FIG. 7, the lever mechanism 28 includes a support member 66 and a lever 68 that is pivotally supported in front of the support member 66 and hangs freely. The support member 66 has two attachment arms 70 and 72 having a width L that protrude downward on the left and right of the rear end portion. The upper part of the portion sandwiched between the mounting arms 70 and 72 forms a semicircular cut 73, and the side surfaces of both ends of the cut 73 have an arch shape that is continuous with the side surfaces of the two mounting arms 70 and 72. ing.
[0057]
The lever 68 has a plate shape in which the lower part is slightly bent toward the front with respect to the upper part. The lever 68 is provided with a relatively large hole 76 slightly below the shaft 74, and has a widened portion 78 widened to the left and right at the lower portion.
[0058]
A small protrusion 80 (see also FIG. 8) is provided on the back surface of the lever 68 so as to protrude rearward.
[0059]
In addition, the lever mechanism part 28 may be provided in the cooling device 100, for example, may be provided in the front door 25 in front of the heat insulation cover 102 in the cooling device 100.
[0060]
Next, a method of assembling the lever mechanism portion 28 to the container main body 22 and the dispensing mechanism portion 26 and a method of dispensing the liquid W stored in the liquid storage container 20 by the action of the lever mechanism portion 28 will be described with reference to FIGS. This will be described with reference to FIG.
[0061]
As shown in FIG. 8, the container main body 22 and the liquid storage bag 24 are arranged such that the liquid storage bag 24 is poured into the notch 46a and 38b (see FIG. 4A) on the jump plate 46 and one side surface 38a. 26 is inserted. Specifically, the peripheral ends of the circular holes formed by the cuts 46a and 38b are engaged with the third annular groove 64c of the extraction mechanism 26, and the outlet 63 of the extraction mechanism 26 faces downward. Is attached.
[0062]
Since the dispensing mechanism portion 26 is formed of a relatively elastic material, it can be engaged with the notches 46a and 38b while deforming the third annular groove 64c. Further, the notch 46a of the jumping plate 46 is set to a sufficiently large shape, and after the pouring mechanism portion 26 is inserted into the large opening portion, it is moved downward so as to be engaged with the notch 38b. It may be.
[0063]
The first annular groove 64a of the dispensing mechanism portion 26 and the groove portions 52 and 54 of the protrusions 49 and 50 face each other to form a vertical through-hole having a width L.
[0064]
The two attachment arms 70 and 72 having a width L in the lever mechanism portion 28 are inserted from above into the through holes formed by the first annular groove 64a and the groove portions 52 and 54, thereby supporting the lever mechanism portion 28. ing. When removing the lever mechanism 28, the attachment arms 70 and 72 may be pulled upward.
[0065]
Since the lower portion of the lever 68 is bent leftward in FIG. 8, it receives a small moment in the counterclockwise rotation direction, and the upper surface of the small protrusion 80 of the lever 68 causes the small protrusion 60 of the plug 58 to be affected by this small moment. It is in contact with the lower surface.
[0066]
As shown in FIG. 9, when the lower portion of the lever 68 is pushed by the cup 300 or by a human hand, a large moment is generated in the lever 68 around the shaft 74, and the lever 68 is counterclockwise in FIG. Tilt in the direction of rotation. At this time, since the hole 68 is provided in the lever 68, the lever 68 and the dispensing mechanism portion 26 do not interfere with each other. Further, since the lower portion of the lever 68 is bent in the left direction in FIG. 9, the lever 68 can sufficiently tilt until the lower portion abuts against the side surface of the base 38 or the machine room 107.
[0067]
When the lever 68 is tilted counterclockwise, the small protrusion 80 of the lever 68 pushes the small protrusion 60 of the plug 58 upward. Thereby, the lower part of the plug 58 is elastically deformed so as to be pulled up, and the seal part 62 is opened. From the opened seal portion 62, the liquid W stored in the liquid storage bag 24 flows out and is poured out through the spout 63 and the hole 76 of the lever 68.
[0068]
The dispensed liquid W is poured into the cup 300. At this time, the cup 300 may be placed on the tray 125 (see FIG. 1), or the lever 68 may be pushed directly by the cup 300. After the appropriate amount of liquid W is injected into the cup 300, when the force applied to the lever 68 is released, the lever 68 is tilted clockwise by the moment due to its own weight and the elastic force that the small protrusion 80 receives from the small protrusion 60, Return to the position shown in FIG. Further, the seal portion 62 is sealed again, and the liquid W is stopped from being poured out.
[0069]
The liquid storage container 20 may have a form as shown in FIG. 10, for example. The liquid storage container 20a shown in FIG. 10 includes a flat bottom heat transfer plate 90 having a cutout at the corner 90a. The bottom heat transfer plate 90 is disposed with the lowest corner 90a and the highest corner 90b. Such a bottom heat transfer plate 90 is easy to process and can be manufactured at a very low cost. In the liquid storage container 20a, the pouring mechanism portion 26 may be inserted downward into the corner portion 90a.
[0070]
Next, a method of folding the liquid storage container 20 will be described with reference to FIGS. 11A to 11C.
[0071]
When the liquid container 20 is folded, all the liquid W inside is poured out and the lever mechanism portion 28 is removed. Moreover, it is good to open the upper surface plates 32 and 34 and to fold the liquid storage bag 24 inside in advance. In addition, in FIG. 11A-FIG. 11C, illustration of the liquid storage bag 24 is abbreviate | omitted for easy understanding.
[0072]
Next, as shown in FIG. 11A, the two jumping plates 46 and 48 are flipped upward. The jumping plates 46 and 48 are housed in a partially overlapping manner.
[0073]
Next, as shown in FIG. 11B, the first divided side plates 42a and 42b are bent inward. Similarly, the second divided side plates 44a and 44b are bent inward.
[0074]
When the first divided side plates 42a and 42b and the second divided side plates 44a and 44b are bent inward, the frame body 40 is lowered and the liquid storage container 20 is folded (see FIG. 11C). In the folded state of the liquid storage container 20, the heights of the first divided side plates 42a and 42b and the second divided side plates 44a and 44b are compressed, and the sum of the height H1 of the base 38 and the height H2 of the frame body 40 is obtained. The height is approximately (H1 + H2). Therefore, the height is reduced and the volume is reduced, which is convenient for storage and transportation. The liquid storage bag 24 may be folded in a detached state.
[0075]
next ,cold The rejection apparatus 100 will be described with reference to FIGS. 12 to 14B.
[0076]
As shown in FIG. 12, the cooling device 100 includes a heat insulating cover 102 that covers the side and upper side of the liquid storage container 20 with a heat insulating material when the liquid storage container 20 is mounted, and the liquid storage container 20 is mounted. And a cooling heat transfer plate 104 made of a copper plate in contact with the bottom heat transfer plate 36 of the liquid storage container 20.
[0077]
The cooling device 100 includes a cooling cycle mechanism 106 (see FIG. 13) that cools the cooling heat transfer plate 104 by performing heat exchange while circulating a refrigerant (HFC 134a or the like). A part of the cooling cycle mechanism 106 is accommodated in the machine room 107.
[0078]
As shown in FIG. 13, the cooling cycle mechanism 106 radiates and dissipates a compressor 108 (also referred to as a compressor) that compresses a gaseous refrigerant by rotation of an internal electric motor, and a refrigerant that has been compressed to a high temperature and a high pressure. And a condenser 110 (also referred to as a condenser) that condenses into a liquid state. Further, the cooling cycle mechanism 106 includes a capillary tube 112 that mists the refrigerant liquefied by the condenser 110, and an evaporator 114 that evaporates the mist refrigerant and absorbs heat of vaporization to perform a cooling action. The refrigerant which has been vaporized by the evaporator 114 and has a relatively low temperature and low pressure is led to the compressor 108 and circulated and constitutes a so-called cooling cycle.
[0079]
The capillary tube 112 has a function of making the refrigerant in a gas-liquid mixed state into a mist by a pipe resistance, and the vaporization heat absorption function in the evaporator 114 can be adjusted by the length of the capillary tube 112. In the liquid cooling system 10, since the liquid W is used for drinking, the length of the capillary tube 112 is set so that the liquid W has an appropriate temperature for drinking (approximately 5 to 10 [deg.] C.).
[0080]
The evaporator 114 is composed of a copper pipe with good heat transfer because of heat exchange, and is a multistage folded pipe line so that the refrigerant can be sufficiently vaporized. The evaporator 114 is not limited to a multistage folded pipeline, and may have any shape as long as the path is long. The evaporator 114 is welded to the cooling heat transfer plate 104.
[0081]
An electric fan 116 is provided in the vicinity of the capacitor 110, and heat dissipation from the capacitor 110 is promoted by receiving the air blown by the electric fan 116. The capacitor 110 is provided with heat radiation fins 110a in order to increase the heat radiation area.
[0082]
In addition to this, the cooling cycle mechanism 106 is provided with a temperature sensor for measuring the temperature of the pipe line or a pressure sensor for measuring the pressure, and when the temperature reaches a predetermined temperature or pressure, the cooling cycle mechanism 106 is interlocked with these temperature sensors or pressure sensors. Thus, the operation of the compressor 108 may be interrupted. In addition, a so-called expansion valve or receiver dryer may be provided. Even if the cooling cycle mechanism 106 has a configuration other than this, the cooling cycle mechanism 106 may be anything as long as the evaporator 114 performs a cooling action.
[0083]
When the operation of the cooling cycle mechanism 106 is started, the compressor 108 and the electric fan 116 are operated by operating a switch (not shown).
[0084]
Returning to FIG. 12, the capacitor 110 is disposed in the vicinity of the side surface in the machine chamber 107, and a vent hole 118 is provided on the side surface for supplying air to the capacitor 110. Further, in order to release the waste heat of the condenser 110 to the outside, a vent hole 120 is also provided on the other surface of the machine room 107.
[0085]
The electric fan 116 is provided in the vicinity of the condenser 110 so that the air supplied from the vent 118 can be supplied via the condenser 110. The air that has absorbed the waste heat from the condenser 110 is exhausted to the vent 120. The air flow may be a flow from the vent 120 toward the vent 118.
[0086]
Further, the compressor 108 and the capillary tube 112 are disposed in the machine chamber 107.
[0087]
An upper surface of the machine chamber 107 serves as a mounting table (mounting unit) 122 for mounting the liquid container 20. The mounting table 122 may have a heat insulating structure to insulate the inside of the machine room 107 and the space in which the liquid storage container 20 is stored. The mounting table 122 is provided with a hole communicating with the inside of the machine chamber 107, and two copper tubes 124 constituting the cooling cycle mechanism 106 pass through the hole. The penetrated copper pipe 124 is connected to the evaporator 114.
[0088]
A plate-like tray 125 for placing the cup 300 is provided in the lower front portion of the machine room 107.
[0089]
The front door 25, which is the front surface of the heat insulating cover 102, has a structure that slides in the vertical direction. As described above, when the front door 25 is opened, the liquid container 20 can be placed and taken out through the opening. FIG. 12 shows a state where the front door 25 is open. When the heat insulating cover 102 is closed (see FIG. 1), the inside of the heat insulating cover 102 is insulated from the outside air.
[0090]
As shown in FIG. 14A, the two copper tubes 124 penetrating the mounting table 122 have diameters at the end portions 124a, and the expanded diameter portions of the openings 114a of the copper tubes constituting the evaporator 114 are respectively provided. Is inserted and welded.
[0091]
The cooling heat transfer plate 104 has substantially the same shape as the bottom surface heat transfer plate 36 (see FIG. 5A), and at least a part of the surface is in surface contact with the bottom surface heat transfer plate 36. Specifically, the cooling heat transfer plate 104 is a copper plate having a gentle substantially V-shaped slope 104a that is symmetrical with respect to the central axis C2. The cooling heat transfer plate 104 has a groove 104b having a substantially semi-conical shape extending along the central axis C2. The groove portion 104b is a large circular groove in which one liquid collecting portion 104c is deeper than the other portion 104d. That is, the shape is set such that the liquid collecting portion 104c is the lowest and becomes higher from the liquid collecting portion 104c toward the other peripheral edge.
[0092]
In order for the cooling heat transfer plate 104 to be in close contact with the bottom surface heat transfer plate 36, the thickness of the groove portion 104 b may be slightly larger than the groove portion 36 b of the bottom surface heat transfer plate 36 in consideration of the thickness of the bottom surface heat transfer plate 36. The cooling heat transfer plate 104 and the bottom heat transfer plate 36 do not necessarily have the same shape. For example, the cooling heat transfer plate 104 and the bottom heat transfer plate 36 may be divided into a plurality of plate materials.
[0093]
Since the cooling heat transfer plate 104 uses copper as a material, it is excellent in thermal conductivity and workability and is inexpensive. The material of the cooling heat transfer plate 104 may be a metal such as aluminum or stainless steel in addition to copper.
[0094]
As can be seen from FIG. 14B when the cooling heat transfer plate 104 is viewed from below, the multistage folded-back evaporator 114 is disposed substantially parallel to the central axis C <b> 2 over substantially the entire surface of the cooling heat transfer plate 104. A part or the entire length of the evaporator 114 is welded to the cooling heat transfer plate 104.
[0095]
The cooling heat transfer plate 104 and the evaporator 114 do not necessarily have to be welded, and may be in contact with each other so that heat conduction is easy. For example, it may be fixed by a bolt / nut configuration.
[0096]
In addition, the cooling heat transfer plate 104 and the evaporator 114 are not necessarily separated from each other. As shown in FIG. 15A, the cooling heat transfer plate 130 is formed by two pressed metal plates, and the pressing is performed. You may make it comprise the fluid channel | path as the evaporator 132. FIG.
[0097]
Further, as shown in FIG. 15B, only the lower one of the two metal plates may be pressed to provide a fluid passage as the evaporator 136 (cooling heat transfer plate 134).
[0098]
Furthermore, as shown in FIG. 15C, a configuration in which the two opposing metal plates are cut on the opposing surfaces and the evaporator 140 is formed by the cut grooves (cooling heat transfer plate 138). It is good. With these configurations, the evaporator and the cooling heat transfer plate are integrated, so that the heat transfer is improved.
[0099]
Returning to FIG. 12, the cooling heat transfer plate 104 and the evaporator 114 are supported by the support table 126 slightly above the mounting table 122, and the cooling heat transfer is performed when the liquid storage container 20 is mounted on the mounting table 122. The position and height are set (or adjusted) so that the plate 104 and the bottom heat transfer plate 36 are in surface contact. At this time, for example, if the support 126 is made of an elastic body, the cooling heat transfer plate 104 and the bottom heat transfer plate 36 are likely to come into surface contact.
[0100]
With such a configuration, the cooling action of the evaporator 114 can cool the liquid W via the cooling heat transfer plate 104, the bottom heat transfer plate 36 and the liquid storage bag 24.
[0101]
Next, a method for cooling the liquid W and pouring the cooled liquid W into the cup 300 using the liquid cooling system 10 configured as described above will be described.
[0102]
First, the liquid W is injected into the liquid storage bag 24 using an appropriate filling device. At this time, the dispensing mechanism 26 may be removed. The liquid storage bag 24 into which the liquid W has been injected is assembled to the liquid storage container 20 in a state of being taken out from the cooling device 100, and the lever mechanism 28 is attached to the liquid storage container 20 (see FIG. 8).
[0103]
Next, the front door 25 (see FIG. 12) is slid upward to open the front surface of the heat insulating cover 102, and the liquid storage container 20 is mounted on the mounting table 122 of the cooling device 100. At this time, it is easy to lift if the grip portion 41 of the liquid container 20 is gripped.
[0104]
When the liquid storage container 20 is placed on the mounting table 122, the bottom heat transfer plate 36 and the cooling heat transfer plate 104 of the liquid storage container 20 are in surface contact.
[0105]
After the front door 25 is lowered and the liquid storage container 20 is covered with the heat insulating cover 102, the operation of the cooling cycle mechanism 106 (see FIG. 13) is started by a switch operation. By the operation of the cooling cycle mechanism 106, the capacitor 110 releases heat and the evaporator 114 cools.
[0106]
Since the evaporator 114 is welded to the cooling heat transfer plate 104, the cooling heat transfer plate 104 is also cooled at the same time. Further, since the cooling heat transfer plate 104 and the bottom heat transfer plate 36 are in surface contact, the bottom heat transfer plate 36 is also cooled. Further, the liquid W is cooled by the bottom heat transfer plate 36 through a thin resin film. Since the material of the evaporator 114, the cooling heat transfer plate 104, and the bottom heat transfer plate 36 is copper, the heat transfer is good and the cooling is effectively performed. Further, since the resin film of the liquid storage bag 24 is thin, cooling of the liquid W is not hindered. Furthermore, since the bottom surface heat transfer plate 36 is provided with the groove 36b, the area where the bottom surface heat transfer plate 36 and the liquid storage bag 24 are in contact with each other is wide, and heat transfer is easier.
[0107]
In this way, when the cooling cycle mechanism 106 is operated, the liquid W is cooled. Since the cooled liquid W stays at the bottom, the bottom is cooled faster than the top. This is because the specific gravity of water (mineral water) is 4 [° C.] and the specific gravity decreases as the temperature increases. Moreover, since the cooling cycle mechanism 106 is set so that the water is approximately 5 to 10 [deg.] C., the water of 10 [[deg.] C.] or more is cooled and the specific gravity increases and settles to the bottom. .
[0108]
Further, since the liquid storage container 20 is covered with the heat insulating cover 102, the cooled liquid W is prevented from absorbing heat from outside air and rising in temperature. Accordingly, the liquid W and the inside of the heat insulating cover 102 are kept at a low temperature.
[0109]
Next, when pouring the liquid W into the cup 300, the cup 300 is placed on the tray 125, and the lever 68 is tilted by hand. As the lever 68 tilts, the seal portion 62 opens and the liquid W is poured out (see FIG. 9). When the lever 68 is tilted by hand, the widened portion 78 of the lever 68 may be pushed so that the poured water does not reach the hand.
[0110]
Alternatively, the lever 68 may be tilted while the cup 300 is directly applied to the lever 68.
[0111]
Thus, the liquid W can be poured into the cup 300 by an extremely simple operation of tilting the lever 68. In addition, since the liquid W at the bottom, which is cooled more than the top, is injected inside the liquid storage container 20, a stirrer or a stirring operation is unnecessary.
[0112]
Further, the liquid W is directly poured into the cup 300 from the liquid storage container 20. That is, since a hose for introduction into another tank is not connected, the liquid W does not come into contact with the outside air until it is poured out from the liquid storage container 20, and the flavor of the liquid W can be maintained.
[0113]
When the liquid W is poured out, the liquid level in the liquid storage container 20 is lowered. When the liquid level drops to the upper end of the bottom heat transfer plate 36, the remaining liquid W is collected in the groove 36b along the substantially V-shaped inclined surface 36a. When the liquid level further decreases to the groove end portion 36d, the remaining liquid W flows through the groove portion 36b and is collected in the liquid collecting portion 36c. Since the dispensing mechanism portion 26 is provided on the side of the liquid collecting portion 36c, all the liquid W can be dispensed without waste.
[0114]
Next, when all the liquid W has been poured out, the operation of the cooling cycle mechanism 106 is stopped, and then the front door 25 is opened and the liquid storage container 20 is taken out. After removing the lever mechanism 28, the liquid storage container 20 is folded by the above procedure (see FIGS. 11A to 11C).
[0115]
Since the volume of the folded liquid container 20 is extremely small, it is suitable for storage or transportation.
[0116]
As described above, according to the liquid cooling system 10, the liquid storage container 20, and the cooling device 100 according to the present embodiment, an auxiliary tank, a circulation pump, a liquid level gauge, a valve linked to the liquid level gauge, and the like are unnecessary. Therefore, the structure becomes extremely simple, and maintenance and maintenance work can be greatly reduced. Therefore, a person in charge of maintenance management is not required, and can be used, for example, in ordinary households.
[0117]
Moreover, since the liquid W is directly poured out from the liquid storage container W, the hose connection work to the auxiliary tank is unnecessary, and the liquid W is not leaked by performing the hose connection work carelessly.
[0118]
Furthermore, the liquid storage container 20 can be reused without being discarded, and the volume can be compressed by the folding structure when the liquid W is not stored. Therefore, it is convenient for storage and suitable for use as a so-called returnable box.
[0119]
In the above-described embodiment, the liquid storage container 20 has been illustrated as being taken out from the opening of the front door 25. However, the liquid storage container 20 may be pulled out from the mounting table 122 by a slide rail or the like. Good. In this case, the liquid storage container 20 does not necessarily have a structure that can be removed from the slide rail. That is, the liquid storage container 20 and the cooling device 100 may be integrated via the slide rail. In this case, only the liquid storage bag 24 may be removed. Further, in order to facilitate the removal of the liquid storage bag 24, the top surface of the liquid storage container 20 is opened, and the front side surface (the side plate corresponding to the jumping plate 46) of the four side surfaces is a pouring mechanism. The portion 26 may have a guide shape so that it can be easily assembled to the dispensing mechanism attachment portion (the portion corresponding to the cut 46a and the cut 38b).
[0120]
Furthermore, the liquid cooling system according to the present invention and Liquid container Na Of course, the present invention is not limited to the above-described embodiments, and various configurations can be adopted without departing from the gist of the present invention.
[0121]
【The invention's effect】

[0122]
In addition, the liquid storage container according to the present invention can be reused, and the effect that the volume can be compressed by the folding structure when the liquid is not stored is achieved.
