Description

本発明は、冷却された液体を製造するための冷却液体製造装置に関する。 The present invention relates to a cooling liquid manufacturing apparatus for manufacturing a cooled liquid.

冷水を飲みたい時に飲むことができるように、水道水（飲料水）をティーポットなどの容器に入れて、これを冷蔵庫で冷やして保存しておくことが一般的に行われている。しかし、水道水の冷蔵庫での保存は、水道水が腐敗するおそれがあるので、衛生上好ましいとは言えない。そのため、水道から流出する水道水を瞬間的に冷却することのできる飲料水冷却装置があれば、冷水を飲みたいときに作ることができ、また、そのような装置では衛生上の問題も生じないので、広く普及すると思われる。 In general, tap water (drinking water) is put in a container such as a teapot, and then cooled and stored in a refrigerator so that the user can drink cold water. However, storage in tap water in a refrigerator is not preferable for hygiene because tap water may be spoiled. Therefore, if there is a drinking water cooling device that can instantaneously cool the tap water flowing out of the water supply, it can be made when you want to drink cold water, and such a device does not cause sanitary problems. So it seems to be widely spread.

水道水を冷却する装置として、パラフィン族炭化水素からなる蓄熱材を収容した蓄熱容器と、その蓄熱材内に埋設され、水道水が流通する配管と、蓄熱容器に装備されたペルチェ素子とを備えたものが知られている（たとえば、特許文献１参照）。ペルチェ素子により蓄熱容器内の蓄熱材を冷却して、蓄熱材に冷熱を潜熱として蓄積させておけば、配管を流通する水道水を冷却することができる。
特開平９−２１８８１０号公報 As a device for cooling tap water, a heat storage container containing a heat storage material made of paraffinic hydrocarbons, a pipe embedded in the heat storage material and through which tap water flows, and a Peltier element equipped in the heat storage container are provided. Are known (for example, see Patent Document 1). If the heat storage material in the heat storage container is cooled by the Peltier element and cold heat is accumulated as latent heat in the heat storage material, the tap water flowing through the pipe can be cooled.
JP-A-9-218810

しかし、上記のような構成では、配管を流通する水道水を飲用に適した低温（５℃程度）に冷却するためには、十分な冷熱量を蓄熱材に蓄えておかなければならないので、多量の蓄熱材を必要とし、装置（蓄熱容器）のサイズが大型になるという不具合がある。また、蓄熱材に冷熱が蓄えられていないと、水道水を冷却することができないので、ペルチェ素子への通電直後は冷水を得ることができない。ペルチェ素子に常時通電しておけば、いつでも冷水を得ることができるが、消費電力量が多くなり、ランニングコスト（電気代）が高くついてしまう。 However, in the configuration as described above, in order to cool the tap water flowing through the pipe to a low temperature (about 5 ° C.) suitable for drinking, a sufficient amount of cold heat must be stored in the heat storage material. Heat storage material is required, and the size of the device (heat storage container) becomes large. Moreover, since tap water cannot be cooled if cold heat is not stored in the heat storage material, cold water cannot be obtained immediately after energizing the Peltier element. If the Peltier element is always energized, cold water can be obtained at any time, but the power consumption increases and the running cost (electricity cost) increases.

そこで、本発明の目的は、小型化を図ることができ、かつ、ペルチェ素子への通電開始直後から液体を冷却することができる冷却液体製造装置を提供することにある。 Accordingly, an object of the present invention is to provide a cooling liquid manufacturing apparatus that can be downsized and can cool a liquid immediately after the start of energization of a Peltier element.

上記の目的を達成するため、請求項１に記載の発明は、冷却液体製造装置において、冷却するための液体を流通するための通液流路を有する通液部材と、吸熱面および放熱面を有し、前記吸熱面が前記通液部材と接触するように配置されるペルチェ素子と、前記放熱面に接触するように配置され、前記放熱面を冷却するための冷却部材とを備え、前記ペルチェ素子が、前記通液部材を挟んで配置され、前記冷却部材が、前記通液部材を挟んで配置される各前記ペルチェ素子に対して、前記通液部材の反対側にそれぞれ配置されていることを特徴としている。 In order to achieve the above object, the invention according to claim 1 is a cooling liquid manufacturing apparatus comprising: a liquid passing member having a liquid passing passage for circulating a liquid for cooling; a heat absorbing surface and a heat radiating surface. A Peltier element disposed so that the heat absorbing surface is in contact with the liquid passing member; and a cooling member disposed so as to be in contact with the heat radiating surface and cooling the heat radiating surface. An element is disposed across the liquid passing member, and the cooling member is disposed on the opposite side of the liquid passing member with respect to each Peltier element disposed across the liquid passing member. It is characterized by.

このような構成によると、ペルチェ素子の吸熱面が通液部材と接触するように配置されているので、ペルチェ素子に直流電流を通電しながら、通液流路に液体を流通させることによって、その通液流路を流通する液体を冷却することができる。
そして、ペルチェ素子が通液部材を挟んで配置されているので、通液流路を流通する液体をペルチェ素子の対向方向両側から冷却（吸熱）することができる。しかも、ペルチェ素子の放熱面を冷却部材によって冷却することができるので、ペルチェ素子の冷却能力を良好に発揮させることができる。そのため、通液流路を流通する液体の効率的な冷却を達成することができ、ペルチェ素子への通電開始直後から通液流路を流通する液体を十分に冷却することができる。その結果、ペルチェ素子への常時通電を不要とすることができるので、ランニングコストの低減化を図ることができる。また、冷熱を蓄えておくための蓄熱材を不要とすることができので、装置の小型化を図ることもできる。 According to such a configuration, since the heat absorption surface of the Peltier element is arranged so as to contact the liquid passing member, the liquid flows through the liquid flow path while passing a direct current through the Peltier element. The liquid flowing through the liquid flow path can be cooled.
And since the Peltier element is arrange | positioned on both sides of a liquid flow member, the liquid which distribute | circulates a liquid flow path can be cooled (heat absorption) from the opposing direction both sides of a Peltier element. In addition, since the heat dissipation surface of the Peltier element can be cooled by the cooling member, the cooling ability of the Peltier element can be exhibited well. Therefore, efficient cooling of the liquid flowing through the liquid flow path can be achieved, and the liquid flowing through the liquid flow path can be sufficiently cooled immediately after the start of energization to the Peltier element. As a result, it is possible to eliminate the need to constantly energize the Peltier element, so that the running cost can be reduced. Moreover, since the heat storage material for storing cold heat can be made unnecessary, the apparatus can be downsized.

また、請求項２に記載の発明は、請求項１に記載の発明において、前記冷却部材は、冷却媒体を流通するための冷却流路を有し、前記冷却流路が、複数形成されていることを特徴としている。
このような構成によると、冷却部材に複数の冷却流路が形成されているので、ペルチェ素子の放熱面を十分に冷却することができる。そのため、ペルチェ素子の冷却能力をより良好に発揮させることができる。 The invention according to claim 2 is the invention according to claim 1, wherein the cooling member has a cooling channel for circulating a cooling medium, and a plurality of the cooling channels are formed. It is characterized by that.
According to such a configuration, a plurality of cooling flow paths are formed in the cooling member, so that the heat dissipation surface of the Peltier element can be sufficiently cooled. Therefore, the cooling capacity of the Peltier element can be exhibited better.

また、請求項３に記載の発明は、請求項２に記載の発明において、前記通液流路および／または前記冷却流路が、断面Ｈ型形状に形成されていることを特徴としている。
このような構成によると、通液流路が断面Ｈ型形状に形成されていれば、通液流路を流れる液体と通液部材との間での熱交換効率を向上させることができる。そのため、ペルチェ素子からの冷熱によって、通液流路を流れる液体をより低温に冷却することができる。 According to a third aspect of the present invention, in the second aspect of the present invention, the liquid flow path and / or the cooling flow path are formed in an H-shaped cross section.
According to such a configuration, if the liquid passage is formed in an H-shaped cross section, the heat exchange efficiency between the liquid flowing through the liquid passage and the liquid passage member can be improved. Therefore, the liquid flowing through the liquid passage can be cooled to a lower temperature by the cold heat from the Peltier element.

また、冷却流路が断面Ｈ型形状に形成されていれば、冷却流路を流れる冷却媒体と冷却部材との間での熱交換効率を向上させることができる。そのため、ペルチェ素子の放熱面を十分に冷やすことができ、ペルチェ素子の冷却能力を一層良好に発揮させることができる。よって、通液流路を流れる液体をより低温に冷却することができる。 Further, if the cooling channel is formed in an H-shaped cross section, the heat exchange efficiency between the cooling medium flowing through the cooling channel and the cooling member can be improved. Therefore, the heat dissipation surface of the Peltier element can be sufficiently cooled, and the cooling ability of the Peltier element can be exhibited more satisfactorily. Therefore, the liquid flowing through the liquid passage can be cooled to a lower temperature.

図２および図７を参照して、ペルチェ素子３は、多数のＰ型半導体とＮ型半導体とを交互に直列接続して形成された半導体デバイスであり、Ｐ型半導体およびＮ型半導体への直流電流の通電によって相関的に吸熱（冷却）現象および放熱現象を生じる吸熱面３Ａおよび放熱面３Ｂを有している。そして、この冷水製造装置１では、通水部材２と各冷却部材４との各間に、２４個のペルチェ素子３が、吸熱面３Ａを通水部材２に接触させ、放熱面３Ｂを各冷却部材４に接触させた状態で配置されている。より具体的には、図７に示すように、冷却部材４の各領域１９Ａ，１９Ｂ，１９Ｃ（通水部材２における各領域９Ａ，９Ｂ，９Ｃ）上において、それぞれ８個のペルチェ素子３が４行×２列の行列状に配置されている。 2 and 7, Peltier element 3 is a semiconductor device formed by alternately connecting a large number of P-type semiconductors and N-type semiconductors in series, and direct current to P-type semiconductors and N-type semiconductors. It has an endothermic surface 3A and a heat radiating surface 3B that generate an endothermic (cooling) phenomenon and a heat radiating phenomenon in correlation with current flow. And in this cold water manufacturing apparatus 1, 24 each Peltier device 3 makes the heat absorption surface 3A contact the water supply member 2 between each water flow member 2 and each cooling member 4, and each heat radiation surface 3B is each cooled. They are arranged in contact with the member 4. More specifically, as shown in FIG. 7, each of the eight Peltier elements 3 is four on each of the regions 19 A, 19 B, 19 C (each region 9 A, 9 B, 9 C in the water passage member 2) of the cooling member 4. They are arranged in rows and columns.

以上のような構成によると、通水部材２の一方側面の水流入出口１８に水を供給するための給水管（図示せず）を接続し、他方側面の水流入出口１８に冷水を排出するための冷水配管（図示せず）を接続して、通水部材２の通水流路７に水を流通させる一方で、各ペルチェ素子３に直流電流を通電させることによって、通水流路７を流れる水を冷却することができる。また、各冷却部材４の一方側面の３つの冷却水流入出口３１に冷却水を供給するための冷却水供給管（図示せず）をそれぞれ接続し、他方側面の３つの冷却水流入出口に冷却水を排出するための冷却水排出管（図示せず）をそれぞれ接続して、冷却部材４の冷却流路２１に冷却水を流通させることによって、各ペルチェ素子３の放熱面３Ｂを冷却することができる。 According to the above configuration, a water supply pipe (not shown) for supplying water is connected to the water inlet / outlet 18 on one side surface of the water passage member 2, and cold water is discharged to the water inlet / outlet port 18 on the other side surface. For this purpose, a chilled water pipe (not shown) is connected to circulate water through the water flow path 7 of the water flow member 2, while a DC current is passed through each Peltier element 3 to flow through the water flow path 7. The water can be cooled. In addition, cooling water supply pipes (not shown) for supplying cooling water to the three cooling water inflow / outflow ports 31 on one side surface of each cooling member 4 are respectively connected, and cooling is performed on the three cooling water inflow / outflow ports on the other side surface. Cooling the heat radiating surface 3B of each Peltier element 3 by connecting a cooling water discharge pipe (not shown) for discharging water and circulating the cooling water through the cooling flow path 21 of the cooling member 4. Can do.

そして、各ペルチェ素子３が通水部材２を挟んでそれぞれ配置されているので、通水流路７を流通する水を各ペルチェ素子３の吸熱面３Ａによって、その対向方向両側から冷却（吸熱）することができる。しかも、各ペルチェ素子３の放熱面３Ｂを各冷却部材４によってそれぞれ冷却することができるので、ペルチェ素子３の冷却能力を良好に発揮させることができる。そのため、通水流路７を流通する水の効率的な冷却を達成することができ、各ペルチェ素子３への通電開始直後から通水流路７を流通する水を十分に冷却することができる。その結果、各ペルチェ素子３への常時通電を不要とすることができるので、ランニングコストの低減化を図ることができる。また、冷熱を蓄えておくための蓄熱材を不要とすることができので、装置の小型化を図ることもできる。 Since each Peltier element 3 is arranged with the water passage member 2 interposed therebetween, the water flowing through the water flow passage 7 is cooled (heat absorption) from both sides in the opposite direction by the heat absorption surface 3A of each Peltier element 3. be able to. Moreover, since the heat radiating surface 3B of each Peltier element 3 can be cooled by each cooling member 4, the cooling ability of the Peltier element 3 can be exhibited well. Therefore, efficient cooling of the water flowing through the water flow channel 7 can be achieved, and the water flowing through the water flow channel 7 can be sufficiently cooled immediately after the start of energization of each Peltier element 3. As a result, since it is not necessary to energize each Peltier element 3 at all times, the running cost can be reduced. Moreover, since the heat storage material for storing cold heat can be made unnecessary, the apparatus can be downsized.

また、この冷水製造装置１では、各冷却部材４に複数（３本）の冷却流路２１が形成されているので、各ペルチェ素子３の放熱面３Ｂを十分に冷却することができる。そのため、各ペルチェ素子３の冷却能力をより良好に発揮させることができる。
さらに、通水部材２に本体側対向壁１４および蓋側対向壁１７が設けられることによって、通水流路７が断面Ｈ型形状に形成されているので、通水流路７を流れる水と本体側対向壁１４および蓋側対向壁１７との間においても熱交換を達成することができる。そのため、通水流路７において広い伝熱面積を確保することができ、通水流路７を流れる水と通水部材２との間での熱交換効率を向上させることができる。その結果、ペルチェ素子３からの冷熱によって、通水流路７を流れる水をより低温に冷却することができる。 Moreover, in this cold water manufacturing apparatus 1, since the multiple (three) cooling flow paths 21 are formed in each cooling member 4, the heat radiation surface 3B of each Peltier element 3 can be sufficiently cooled. Therefore, the cooling capacity of each Peltier element 3 can be exhibited more satisfactorily.
Further, since the water flow member 7 is provided with the main body side facing wall 14 and the lid side facing wall 17, the water flow channel 7 is formed in an H-shaped cross section, so that the water flowing through the water flow channel 7 and the main body side Heat exchange can also be achieved between the facing wall 14 and the lid-side facing wall 17. Therefore, a wide heat transfer area can be ensured in the water flow channel 7, and the efficiency of heat exchange between the water flowing through the water flow channel 7 and the water flow member 2 can be improved. As a result, the water flowing through the water flow passage 7 can be cooled to a lower temperature by the cold heat from the Peltier element 3.

また、冷却部材４に本体側対向壁２７および蓋側対向壁３０が設けられることによって、冷却流路２１が断面Ｈ型形状に形成されているので、冷却流路２１を流れる冷却水と本体側対向壁２７および蓋側対向壁３０との間においても熱交換を達成することができる。そのため、冷却流路２１において広い伝熱面積を確保することができ、冷却流路２１を流れる冷却水と冷却部材４との間での熱交換効率を向上させることができる。その結果、各ペルチェ素子３の放熱面３Ｂを各冷却部材４によって十分に冷やすことができ、ペルチェ素子３の冷却能力を一層良好に発揮させることができる。よって、通水流路７を流れる水をより低温に冷却することができる。 Further, since the cooling member 4 is provided with the main body side facing wall 27 and the lid side facing wall 30, the cooling flow path 21 is formed in an H-shaped cross section, so that the cooling water flowing through the cooling flow path 21 and the main body side Heat exchange can also be achieved between the facing wall 27 and the lid-side facing wall 30. Therefore, a wide heat transfer area can be secured in the cooling channel 21, and the efficiency of heat exchange between the cooling water flowing in the cooling channel 21 and the cooling member 4 can be improved. As a result, the heat radiation surface 3B of each Peltier element 3 can be sufficiently cooled by each cooling member 4, and the cooling ability of the Peltier element 3 can be exhibited more satisfactorily. Therefore, the water flowing through the water flow passage 7 can be cooled to a lower temperature.

さらにまた、ペルチェ素子３への通電開始直後から通水流路７を流通する水を十分に冷却することができる小型の冷水製造装置１は、家庭用や小規模業務用の飲料水の製造装置として好適に用いることができる。

It can be used suitably.
In this embodiment, on each region 19A, 19B, 19C of the cooling member 4 (each region 9A, 9B, 9C of the water passage member 2), eight Peltier elements 3 are each arranged in a matrix of 4 rows × 2 columns. However, the number and arrangement of the Peltier elements 3 may be appropriately changed so that water is efficiently cooled. For example, the cooling target temperature of the water flowing through the water flow path 7 is set for each of the regions 9A, 9B, 9C of the water flow member 2 (for example, the cooling target temperature in the region 9A is 20 ° C., and the cooling target temperature in the region 9B is set). Is set to 10 ° C. and the target cooling temperature in the region 9C is 5 ° C.), and the number and arrangement of the Peltier elements 3 may be determined so that the respective cooling target temperatures are achieved. Further, the water flow member 2 (groove forming portion 9) is divided into three regions 9A, 9B, 9C, and the water flow channel 7 (water flow channel forming groove 11) is formed in a twisted manner in each of the regions 9A, 9B, 9C. Although formed, the water flow member 2 is divided into four or more areas, and the water flow paths 7 are formed in a twisted manner in each area, and the cooling target of the water flowing through the water flow paths 7 for each area The number and arrangement of the Peltier elements 3 may be determined so that the temperature is set and the cooling target temperature is achieved.
