  Further, a penetrating portion 12 penetrating in the vertical direction into which the mouth portion 9 of the bottle 6 is inserted is formed in the lower central portion of the inclined portion 11. A thick portion 31 (see FIGS. 1 and 3) is formed from the inclined portion 11 of the jacket body 7 to the lower end opening of the penetrating portion 12 so as to surround the mouth portion 9 from the shoulder portion 10 of the bottle 6.

  As shown in FIGS. 1 and 5, the upper end of the jacket 1 (jacket body 7) is open so that the bottle 6 can be replaced with the accommodating portion 8.

  As shown in FIGS. 1 and 3, the lower end portion 5 a of the heat transfer pipe 5 protrudes from the lower portion of the jacket body 7 and is connected to a pump 13 for pumping water. On the other hand, the upper end portion 5b of the heat transfer pipe 5 protrudes in the horizontal direction from the upper portion of the jacket body 7, and is connected to the electromagnetic valve 14 on the intake side.

  As shown in FIG. 3, in order to facilitate the insertion and removal of the bottle 6 from the heat insulating main body 2, the bottle 6 is attached to the heat insulating main body 2 so that the bottom of the bottle 6 can be grasped by hand. The dimensional relationship is such that the bottom part slightly protrudes from the opening end of the heat insulating main body 2, and the bottom part of the bottle 6 protruding from the opening end of the heat insulating main body 2 becomes the knob part 32 (see FIG. 3) of the bottle 6. ing.

  Reference numeral 15 shown in FIGS. 1 and 5 is a unit mounting portion for mounting the electronic temperature control unit 4 provided on the outer peripheral surface of the jacket main body 7 at a flat portion at the approximate center in the height direction.

  The jacket 1 having such a configuration is inserted and fixed at a predetermined position in the heat insulating main body 2, and the outer peripheral surface of the jacket 1 and the inner peripheral surface of the heat insulating main body 2 are in close contact with each other. Furthermore, the upper end portion 1a of the jacket 1 is covered with the upper end portion of the heat insulating body 2 so as not to be exposed when the heat insulating lid 3 is opened.

  As shown in FIG. 3, a small space portion 16 is provided at the bottom of the heat insulating body 2, and a water receiving portion 17 attached to the suction side of the pump 13 below the through portion 12 of the space portion 16. Is installed. The function of the water receiving unit 17 will be described later.

  For example, as shown in FIG. 1, the electronic temperature control unit 4 includes a heat absorption side heat conductor 18, a heat radiation side heat conductor 19, a heat absorption side heat conductor 18, and a heat radiation side heat installed on the outer peripheral surface of the jacket 1 (jacket body 7). The Peltier element 20 interposed between the conductors 19, the heat radiation fin 21 connected to the outside of the heat radiation side heat conductor 19, the heat radiation fan 22 disposed in the vicinity of the heat radiation fin 21, and the power supply to the Peltier element 20 It consists of a power supply control board 23 to be controlled.

  In FIG. 1, reference numeral 24 denotes a temperature sensor attached to the inner surface of the jacket 1 (jacket body 7), which measures the inner surface temperature of the jacket 1 (jacket body 7) when using the cold water dispenser and controls the power of the detection signal. It transmits to the board | substrate 23 and controls the electric power feeding to the Peltier device 20 based on a detection signal.

  In the case of the present embodiment, the temperature sensor 24 is attached to the inner surface of the jacket 1 (jacket body 7) at a position facing the central portion of the electronic temperature control unit 4.

  In the assembled state of the cold water dispenser, as shown in FIG. 3, in the electronic temperature control unit 4, the outer peripheral portions of the heat absorption side heat conductor 18 and the Peltier element 20 are surrounded by a part of the heat insulating body 2, Buried.

  On the other hand, the heat radiation side heat conductor 19, the heat radiation fins 21, the heat radiation fan 22, the power supply control board 23, and the like are installed outside the heat insulating body 2.

  The heat insulating lid 3 disposed on the upper portion of the heat insulating main body 2 is rotatably supported by the heat insulating main body 2 by a hinge portion (not shown).

  As shown in FIG. 1, a cold water intake pipe 25 (hereinafter abbreviated as intake pipe 25) extends downward from the solenoid valve 14 to which the upper end 5b of the heat transfer pipe 5 is connected. A drain pan 27 on which a cup 26 is placed is provided below the water pipe 25.

  The electromagnetic valve 14 is connected to a water intake switch 28 having a built-in LED lamp (not shown), and the water intake switch 28 is connected to a drive control unit (not shown) of the pump 13.

  The electromagnetic valve 14, the drain pan 27, the water intake switch 28, and the like described above are supported by a housing (not shown) including the heat insulating main body 2.

  The cold water dispenser according to the first embodiment is configured as described above. Next, the operation of this cold water dispenser will be described.

  First, with the mouth portion 9 of the bottle 6 containing the drinking water 29 facing upward, the cap (not shown) is turned off to remove the water supply cap 30 using the spiral groove of the mouth portion 9. Screw on. The water supply cap 30 incorporates a check valve (not shown) for preventing the drinking water 29 from coming out even when the mouth portion 9 of the bottle 6 is turned down.

  The heat insulation cap 3 of the cold water dispenser is opened, and the bottle 6 is inserted into the housing portion 8 of the jacket 1 (jacket body 7) in an inverted state with the water supply cap 30 down. This insertion is stably supported and accommodated when the shoulder portion 10 of the bottle 6 comes into close contact with the inclined portion 11 of the jacket body 7.

  By inserting the bottle 6, the water supply cap 30 attached to the bottle 6 enters the water receiving portion 17, and the check valve in the water supply cap 30 is opened by the function of the water receiving portion 17 and at the same time in the bottle 6. Air is sent to allow continuous water flow from the bottle 6, and a part of the drinking water 29 in the bottle 6 flows to the pump 13. After that, the heat insulating lid 3 is closed and the opening of the heat insulating main body 2 is sealed.

  When the water intake switch 28 is turned on in this state, the pump 13 for pumping water is driven, and the drinking water 29 in the bottle 6 passes through the water receiving section 17 -pump 13 -heat transfer pipe 5 and drinks over the entire length of the heat transfer pipe 5. When the water 29 is filled and a part of the drinking water 29 comes out of the water intake pipe 25, the water intake switch 28 is turned off and the drive of the pump 13 is stopped.

  In this state, since the electronic temperature control unit 4 is not supplied with power, the drinking water 29 between the bottle 6 and the heat transfer pipe 5 is at room temperature. Based on the detection signal from the temperature sensor 24 (see FIG. 1), power is supplied from the power supply control board 23 to the electronic temperature control unit 4 to cool the jacket body 7 having the built-in heat transfer pipe 5.

As shown in FIG.
(A). The electronic temperature control unit 4 is installed at a substantially central portion in the height direction of the peripheral surface of the jacket body 7 having a wide endothermic surface,
(B). That most of the bottle 6 is accommodated in the jacket 1 (jacket body 7);
(C). A long passage such as the heat transfer pipe 5 through which the drinking water 29 circulates is formed in the peripheral wall portion of the jacket body 7.
(D). Since the heat radiation from the jacket 1 and the motor 13 to the outside is blocked by the heat insulating body 2 and the heat insulating lid 3, the heat retaining effect is high.
The drinking water 29 in the heat transfer pipe 5 and the bottle 6 is rapidly cooled.

  In particular, the drinking water 29 in the heat transfer pipe 5 is a small amount compared to the drinking water 29 in the bottle 6, and is close to the electronic temperature control unit 4, and the entire periphery has a good heat conductivity. 5 and the jacket body 7, the cooling is performed in a short time to a predetermined temperature.

  When the temperature sensor 24 indirectly detects that the drinking water 29 has been cooled to a predetermined temperature, the LED lamp built in the water intake switch 28 is turned on to indicate that cold water can be taken.

  In this state, when the cup 26 is placed on the drain pan 27 and the intake switch 28 is pushed, the electromagnetic valve 14 is opened, the pumping motor 13 is driven, and the drinking water 29 in the heat transfer pipe 5 is brought into the cold water state. It flows out from the intake pipe 25 and is poured into the cup 26. The drinking water 29 in the bottle 6 is moved into the heat transfer pipe 5 by the motor 13 by the amount of the drinking water 29 taken.

  Even if the entire drinking water 29 in the bottle 6 is not sufficiently cooled, it is sufficiently cooled when passing through the long heat transfer pipe 5, and cold water can be taken from the intake pipe 25.

  When the pressing of the water intake switch 28 is stopped, the motor 13 is stopped, the electromagnetic valve 14 is closed, and the cold water state of the drinking water 29 is maintained by the electronic temperature control unit 4.

  FIG. 6 is a head characteristic diagram showing the relationship between the length of the heat transfer pipe 5 and the head (lift height) of the water when the inner diameter of the heat transfer pipe 5 is changed.

  The heat transfer pipes 5 used in this test are all stainless steel pipes. The dotted line in the figure is the characteristic curve with the inner diameter of the heat transfer pipe 5 being 4 mm, the alternate long and short dash line is the inner diameter of 5 mm, and the solid line is the characteristic curve of 6 mm. The model name of the pump 13 used is TZ623 manufactured by Panasonic, and the specification is DC12V-0.27A. The amount of water supplied to the heat transfer pipe 5 was 400 ml in 10 seconds.

  The pump 13 of the model name is a small and low-cost pump that is widely used in jar pots and the like. By using such a pump 13, it is possible to reduce the size and cost of the temperature control device.

  According to the results of various experiments conducted by the present inventors, it has been found that in the case of a cold water dispenser in which a PET bottle having a storage capacity of 2 L can be attached, a lift of the heat transfer pipe is sufficient if it is 5 m. It is preferable as a cooling characteristic of the cold water dispenser that the length of the heat transfer pipe is sufficiently long by 0.2 m.

  As is apparent from the test results in FIG. 6, when a heat transfer pipe (indicated by a dotted line) having an inner diameter of 4 mm is used, the length of the heat transfer pipe is 2.2 m at the lift target (see horizontal thin line A in FIG. 6). The length of the heat transfer pipe is 1 m or less, and the heat transfer pipe having an inner diameter of 4 mm is therefore unsuitable for a cold water dispenser.

  Also, when using heat transfer pipes with an inner diameter of less than 5 mm to obtain effective heat exchange performance and an appropriate amount of water, a special high-pressure pump is required, which increases the size of the temperature control device and increases costs. This is not preferable.

  On the other hand, when a heat transfer pipe (indicated by a one-dot chain line) with an inner diameter of 5 mm is used, the length of the heat transfer pipe extends to about 4.5 m at a lift target of 2.2 m, and is about that of a heat transfer pipe with an inner diameter of 4 mm. 5 times more. Further, when a heat transfer pipe (indicated by a solid line) having an inner diameter of 6 mm is used, the length of the heat transfer pipe is about 10 m or more at a lift target of 2.2 m, which is about ten times that of a heat transfer pipe having an inner diameter of 4 mm. From this test result, the inner diameter of the heat transfer pipe used for the cold water dispenser is 5 mm or more, preferably 6 mm or more.

  The upper limit value of the inner diameter of the heat transfer pipe is about 10 mm in consideration of a good cooling effect of drinking water in the heat transfer pipe.

  In this example, a stainless steel heat transfer pipe 5 having an inner diameter of 6 mm, an outer diameter of 8 mm, and a length of about 5.5 m was used, and the number of turns of the heat transfer pipe 5 (see FIG. 1) was 10 turns.

  FIG. 7 shows that the cold water dispenser according to the present example is preliminarily mounted with a 2 L plastic bottle and cooled, and the cooled plastic bottle is taken out and replaced with a new normal temperature plastic bottle. It is the figure which performed 10 cups of water intake, and measured and collected the water intake temperature and water intake amount in each cup. In FIG. 7, the ● mark indicates the water intake temperature (left vertical axis), and the ◆ mark indicates the water intake amount (right vertical axis).

  The replaced new PET bottle contains drinking water at room temperature of 25 ° C, but the drinking water from the PET bottle before the replacement remains filled in the heat transfer pipe 5 in the cold water state. The jacket 1 filled with cold water has a predetermined area and thickness, has a large heat capacity, and since the entire jacket 1 is once cooled, cold water of 10 ° C. or less is supplied to 1 to 3 cups. Can take water.

  In the fourth cup, the intake temperature is 10 ° C., and the intake temperature rises slightly for each intake, but the jacket 1 has a large heat capacity, so the intake temperature does not increase rapidly. I understand.

  Although FIG. 7 shows the change in the intake water temperature immediately after the bottle replacement, when the bottle has been replaced and time has passed, the cooling of the drinking water 29 in the replaced bottle 6 has progressed, whereby the intake water temperature is 10 ° C. or less. It has been confirmed in other experiments.

  Since the electronic temperature control unit 4 is used in the present invention, the cold water dispenser is used as the hot water dispenser by providing polarity switching means for switching the polarity of power feeding to the Peltier element 20 and switching the polarity to the Peltier element 20. You can also

  Further, since the Peltier element 20 is used, the heating operation can be simplified. For example, the water supply system such as the water supply cap 30, the water receiving unit 17, the pump 13, the heat transfer pipe 5, the electromagnetic valve 14, and the water intake pipe 25 can be used. For the purpose of heat sterilization and sterilization, the drinking water 29 can be heated to, for example, 50 ° C. or more and passed, which is hygienic.

  In the above embodiment, the heat transfer pipe is mounted in the mold, the molten metal is injected into the mold, and the jacket body in which the heat transfer pipe is insert-molded is formed, but without using the heat transfer pipe, It is also possible to form a jacket body having a long channel such as a spiral inside the peripheral wall by casting.

  In this case, it is necessary to provide an inlet side tube connected to the pump on the channel inlet side of the jacket body and an outlet side tube connected to the solenoid valve on the channel outlet side of the jacket body.

  In the above-described embodiment, an example in which a PET bottle is used as a container for storing a liquid is shown. However, when the amount of stored liquid decreases, it is also possible to use a shrinkable container whose volume naturally shrinks accordingly. It is.

  In the above embodiment, the case where the bottle 6 containing the drinking water 29 is cooled has been described. However, the present invention is not limited to this. For example, in other technical fields such as biomass, a liquid such as a chemical solution is fixed. The present invention is also applicable to a temperature control device that maintains a temperature cooling state or a heating state.

(Example 2)
FIG. 8: is the schematic side view which made a part the cross section except the heat insulation main body and heat insulation lid | cover of the cold water dispenser which concern on Example 2 of this invention.

  The second embodiment is different from the first embodiment shown in FIG. 1 in the configuration of the jacket 1.

  In the present embodiment, the jacket 1 has an inner container 41 formed in accordance with the outer peripheral shape of the bottle 6 to be accommodated, and a transmission that is disposed on the outer periphery of the inner container 41 and is bent in a spiral manner as in the first embodiment. A heat pipe 5, an outer container 42 arranged outside the heat transfer pipe 5, and a liquid heat medium 43 filled in a gap formed between the inner container 41, the heat transfer pipe 5 and the outer container 42. Has been.

  The inner container 41 and the outer container 42 are made of a thin aluminum pressed product, and have a double structure in which the inner container 41 is disposed inside the outer container 42. An insertion hole 44 through which the water supply cap 30 attached to the bottle 6 passes is formed at the bottom center of the inner container 41 and the outer container 42.

  The bottom portions of the inner container 41 and the outer container 42 are continuously welded (not shown) so as to surround the insertion hole 44. This welding is useful for preventing leakage of the heat medium 43 from the insertion hole 44.

  On the outer peripheral surface of the outer container 42, a unit mounting portion 15 is provided in a flat portion at a substantially central position in the height direction, and the electronic temperature control unit 4 is mounted there.

  In this embodiment, the heat transfer pipe 5 is in contact with the inner container 41, but may be in contact with the outer container 42. Further, the heat transfer pipe 5 can be brought into contact with both the inner container 41 and the outer container 42.

  In the first embodiment, since the jacket body 7 is formed by casting, the material of the heat transfer pipe 5 is limited to a material having a melting point higher than that of the jacket body 7, but in this embodiment, it is not based on casting. A material having high thermal conductivity such as copper or stainless steel can be used as the heat pipe 5, and the heat exchange performance with the fluid in the pipe (drinking water 29 in this embodiment) can be improved.

  As the liquid heat medium 43, for example, a liquid material having a large specific heat such as water, antifreeze liquid, oil, or gel is used. In order to prevent the liquid heat medium 43 from drying, the upper end opening of the outer container 42 is covered and sealed by the upper portion of the heat insulating body 2 like the upper end 1a of the jacket 1 in FIG.

  The jacket 1 of the present embodiment can be reduced in weight and size than the jacket 1 of the first embodiment, and the cold water dispenser can be reduced in weight and size.

The second electromagnetic valve 54 and a hot water intake pipe 55 extending from the second electromagnetic valve 54 are configured.

  Although not shown, the second electromagnetic valve 54 is connected to a water intake switch capable of selecting cold water and hot water, and this water intake switch is connected to the pump 13 and the first electromagnetic valve 52 that is driven when hot water is taken. Has been.

  Although a heating mechanism having various structures can be used as the heating mechanism 53, a tankless heating mechanism that does not use a tank for heating the drinking water 29 is used in this embodiment. This tankless heating mechanism has features such as a small number of parts, high thermal efficiency, miniaturization, and low cost.

  FIG. 10 is a cross-sectional view showing an example of a tankless heating mechanism.

  In this tankless heating mechanism 53, a heat transfer pipe 56 (hereinafter abbreviated as heat transfer pipe 56) that is spirally wound and has a long pipe length, and one or more rod sheath heaters 57 are cast. Mounted inside (not shown). As shown in FIG. 10, the rod seed heater 57 is disposed at a position inside the heat transfer pipe 56.

  In this state, an aluminum die-cast heating main body in which a heat transfer pipe 56 and a rod sheath heater 57 are insert-molded (embedded) by pouring molten metal of aluminum having good thermal conductivity into a mold and solidifying by cooling. 58 is configured.

  When the rod sheath heater 57 is energized, it generates heat, and the heat is transmitted to the heat transfer pipe 56 via the heating body 58 having good heat conductivity, so that the entire heating mechanism 53 becomes a high temperature state, and the heat transfer pipe 56 is heated. The drinking water 29 circulating inside is heated to a predetermined temperature.

  In the case of this tankless heating mechanism, the heat transfer pipe 56 and the rod sheath heater 57 are insert-molded (embedded), and a thick aluminum die-cast heating body 58 is used, so that it has a large heat capacity. Tankless heating mechanism. And since the whole heating mechanism 53 is once warmed, even if it replaces | exchanges for the new bottle 6, the warm drinking water 29 can be taken in immediately.

  In this embodiment, the rod sheath heater 57 is used as a heating source for insert molding (embedding) in the heating body 58. However, it is also possible to insert mold (embedding) another heating source in the heating body 58. .

  FIG. 11 is a cross-sectional view showing another example of the tankless heating mechanism.

  The tankless heating mechanism 53 includes a tubular ceramic heater 59, a cylindrical member 60 that houses the ceramic heater 59, and a lid member 61 that closes the upper end opening of the cylindrical member 60.

  The ceramic heater 59 has a circular tubular shape, and a conductive pattern (not shown) patterned in a continuous spiral is formed inside the peripheral wall thereof. The ceramic heater 59 is installed in the cylindrical member 60 in a state of being attached to the lid member 61 through the central portion of the lid member 61, but the lower end portion of the ceramic heater 59 is lower than the bottom surface of the cylindrical member 60. It is fixed in a slightly floating state.

  A spirally formed guide member 62 is mounted between the outer peripheral surface of the ceramic heater 59 and the inner peripheral surface of the cylindrical member 60, and the helical flow path 63 is formed by the ceramic heater 59, the cylindrical member 60, and the guide member 62. Is formed.

  The cylindrical member 60 and the guide member 62 are made of a metal having good thermal conductivity such as copper or stayless steel. When the conductive pattern of the ceramic heater 59 is energized, the entire ceramic heater 59 generates heat, and the heat is transmitted to the cylindrical member 60 through the guide member 62, so that the entire heating mechanism 53 is in a high temperature state.

  When drinking water 29 is passed from the upper part of the circular ceramic heater 59, the drinking water 29 is first heated by the ceramic heater 59. The flow of the drinking water 29 that has exited from the lower end opening of the ceramic heater 59 is redirected at the inner bottom of the cylindrical member 60 and flows into the flow path 63.

  Since the drinking water 29 is heated again by the ceramic heater 59 and the heated cylindrical member 60 and the guide member 62 in the flow path 63, the drinking water heated to a predetermined temperature from the outlet side of the heating mechanism 53. 29 is obtained.

  Since the ceramic heater 59 has a high heat generation density, the heating speed of the drinking water 29 is high. Further, the heating mechanism 53 can be made compact.

  The entire outer periphery of the heating mechanism 53 shown in FIG. 10 and FIG. 11 is covered with a heat insulating member (not shown) to block heat dissipation from the heating mechanism 53 to the outside.

  Also in the temperature control apparatus according to the third embodiment, both cold water and hot water can be taken. In addition, the drinking water 29 is set to, for example, 50 ° C. or higher by the heating mechanism 53 for the purpose of heat sterilization and sterilization of a water supply system such as the branch pipe 51, the first and second electromagnetic valves 52 and 54, and the hot water intake pipe 55. It is hygienic because it can be heated and passed.

  In the third embodiment, as shown in FIG. 9, the branch pipe 51 and the heating mechanism 53 are attached to the jacket 1 shown in FIG. 1, but the branch pipe 51 and the heating mechanism 53 are added to the jacket 1 of another structure shown in FIG. 8. It is also possible to attach.

The main effects of the embodiment of the present invention are summarized as follows.
(1) Since the cooling state or the heating state can be maintained from the container 6 mounted in the temperature control device to the water supply system such as the pump 13 and the heat transfer pipe 5, it is easy to perform hygiene maintenance management.
(2) Since the jacket body 7 in which the heat transfer pipe 5 is insert-molded inside the peripheral wall is used, the heat exchange performance between the heat transfer pipe 5 and the jacket body 7 can be maintained high. In addition, since the heat exchange performance is high, the drinking water can be cooled or heated even if the heat transfer pipe 5 is short.
Further, since the jacket body 7 has a large heat capacity, the cooling state or heating state of the temperature control device can be maintained for a long time.
(3) The bent heat transfer pipe 5 is inserted between the double structure of the inner container 41 and the outer container 42 made of a thin aluminum pressed product, and the inner container 41, the heat transfer pipe 5, and the outer container 42 are inserted. In the jacket main body 7 in which the space formed between them is filled with a liquid heat medium 43 such as water or antifreeze, the heat exchange performance between the drinking water 29 and the heat transfer pipe 5 is smaller than that of the first embodiment, but the specific heat is large. Therefore, it is possible to reduce the weight and size.
In addition, a material having high thermal conductivity such as copper can be used for the heat transfer pipe 5, and the heat exchange performance with the fluid in the pipe is improved.
(4) When the electronic temperature control unit 5 including the Peltier element is used, the heating operation can be easily performed by switching the polarity. Therefore, the heat sterilization process in the water intake system can be appropriately performed, and hygiene maintenance management is easy. .
(5) Since the bottle 6 is installed in an inverted state in the temperature control device, and the cooling head pump 13 is installed in the cooling state below the mouth of the bottle 6, it is effective for hygiene maintenance.
(6) Since the temperature control means such as the electronic temperature control unit 5 is attached to the outer surface of the peripheral wall of the jacket body 7, the jacket body 7 (bottle 6) can be generally temperature-controlled over a wide area, and the heat transfer efficiency Is good.

  In addition, since the temperature adjusting means is not disposed below the bottle 6, it is possible to reduce the height of the temperature adjusting device and to provide a stable temperature adjusting device that is difficult to overturn.
