Description

本発明は、加熱装置に関し、より詳しくは、湯沸かし器に関するものである。   The present invention relates to a heating device, and more particularly to a water heater.

一般的に、従来の湯沸かし器としては、ガス湯沸かし器と、電気湯沸かし器がある。ガス湯沸かし器は、連続したＳ字パイプが中にあり、また、そのパイプを直接加熱するガスバーナーがある。電気湯沸かし器には２種類ある。第１の種類は、水を直接加熱するための電気ヒーターを有する。第２の種類は、電磁気式加熱手段を有し、この電磁気式加熱手段は、渦電流を生成して金属ブロックに電気を誘導し、次に水がその金属ブロックの中を流れて加熱される。一般的に、ガス湯沸かし器の方が電気湯沸かし器よりも効率が低く、また、ガス湯沸かし器は、事故を防ぐために、ガス湯沸かし器を取り付ける場所についての換気問題を考えなければならない。ガス湯沸かし器の別の問題は、普通、湯沸かし器と水道栓との間の距離が長く、使用者は水が出てくるまでにパイプ内の冷水が流れ出ててしまうのを待たねばならないことであり、また、熱量もその長いパイプの中で失われるであろうことである。ガス湯沸かし器の別の問題は、温度調節である。これも、長いパイプによって生じることであるが、温度変化の反応時間が遅すぎて、使用者は、普通、水温が設定温度に変えられたときに、過剰に調節をして、水温を熱くし過ぎたり、冷たくし過ぎたりするのである。一部の小型湯沸かし器は中に貯水槽がなく、このような湯沸かし器は家の中に取り付けることができる。これの利点は、温度調節における反応が早いことであり、また、これの欠点は、十分な温水を供給できないことである。現在の市場には大型の電気湯沸かし器があり、これらは十分な温水を供給しうる。しかしながら、取り付け場所が限られており、また、依然として、湯沸かし器と水道栓との間の距離が長すぎるという問題を有する。   Generally, as a conventional water heater, there are a gas water heater and an electric water heater. A gas water heater has a continuous S-shaped pipe inside, and a gas burner that directly heats the pipe. There are two types of electric water heaters. The first type has an electric heater for directly heating the water. The second type has an electromagnetic heating means that generates eddy currents to induce electricity in the metal block, and then water flows through the metal block and is heated. . In general, gas water heaters are less efficient than electric water heaters, and gas water heaters must consider ventilation problems where the gas water heater is installed to prevent accidents. Another problem with gas water heaters is that usually the distance between the water heater and the water tap is long, and the user must wait for the cold water in the pipe to flow out before the water comes out, Also, the amount of heat will be lost in the long pipe. Another problem with gas water heaters is temperature regulation. This is also caused by a long pipe, but the reaction time of the temperature change is too slow, and when the water temperature is changed to the set temperature, the user usually over-adjusts and makes the water temperature hot. It is too cold or too cold. Some small water heaters do not have a reservoir inside, and such water heaters can be installed in the house. The advantage of this is that the reaction in temperature control is fast, and the disadvantage of this is that sufficient hot water cannot be supplied. There are large electric water heaters in the current market, which can supply enough hot water. However, the installation location is limited, and there is still a problem that the distance between the water heater and the water tap is too long.

本発明の主目的は、加熱効率が優れていて、節電をし、熱湯を十分供給する湯沸かし器を提供することである。   The main object of the present invention is to provide a water heater that has excellent heating efficiency, saves power, and sufficiently supplies hot water.

本発明の目的によれば、湯沸かし器は、気密な空洞部を中に有する筐体と、筐体の空洞部に入れられていて、第１接続端部及び第２接続端部がそれぞれ筐体から延び出している配水管と、室温で液体であり、筐体の空洞部に入れられている熱媒体と、直接又は間接に熱媒体を加熱する加熱装置とを含む。   According to the object of the present invention, the water heater is placed in a casing having an airtight cavity therein, and in the cavity of the casing, and the first connection end and the second connection end are respectively separated from the casing. It includes a water pipe that extends, a heat medium that is liquid at room temperature and contained in a cavity of the housing, and a heating device that heats the heat medium directly or indirectly.

（第１実施形態）
図１及び図２に示されているように、本発明の第１実施形態の湯沸かし器１０は以下のものを含む。
筐体２０は、１気圧よりも圧力が低い気密な空洞部３０を有する。空洞部３０は、真空であることが好ましい。空洞部３０内で必要とされる圧力は、１０−１トル未満であり、より好ましくは１０−２トル未満であり、さらに好ましくは１０−３トル未満である。 (First embodiment)
As shown in FIGS. 1 and 2, the water heater 10 according to the first embodiment of the present invention includes the following.
The housing 20 has an airtight cavity 30 whose pressure is lower than 1 atmosphere. The cavity 30 is preferably a vacuum. The pressure required within the cavity 30 is less than 10-1 Torr, more preferably less than 10-2 Torr, and even more preferably less than 10-3 Torr.

配水管４０は、筐体２０に取り付けられ、連続したＳ字形状のパイプであり、筐体２０の両側からそれぞれ筐体２０の外へ延びる第１接続端部４１と、第２接続端部４２とを有する。図２に示されているように、第２接続端部がより高い位置にあり、第２接続端部がより低い位置にある。配水管４０の第１接続部４１及び第２接続端部４２は、空洞部３０の気密状態を保持するために、外部のパイプに接続されたコネクターまで延びている。   The water distribution pipe 40 is a continuous S-shaped pipe attached to the housing 20, and includes a first connection end 41 and a second connection end 42 that extend from both sides of the housing 20 to the outside of the housing 20. And have. As shown in FIG. 2, the second connection end is at a higher position and the second connection end is at a lower position. The first connection portion 41 and the second connection end portion 42 of the water distribution pipe 40 extend to a connector connected to an external pipe in order to maintain the airtight state of the cavity portion 30.

蒸発温度が低く、室温で液体である熱媒体５０が筐体２０の空洞部３０に入っている。この熱媒体５０はあまり沢山必要ない。熱媒体５０は、空洞部２０の容積の１．５％から２０％充填されており、好ましくは２％から１５％充填されており、より好ましくは１０％充填されている。熱媒体５０の量について考えるべきことは、費用と熱伝達効率である。空洞部３０内の熱媒体５０のあらゆる量が依然として本発明の範囲内にあるべきである。熱媒体は、高揮発性の物質であり、例えば、エーテル、アルコール、ベンジン若しくはこれらの混合物又は他の適切な物質であってもよい。   A heat medium 50 having a low evaporation temperature and being a liquid at room temperature enters the cavity 30 of the housing 20. The heat medium 50 is not so much needed. The heat medium 50 is filled from 1.5% to 20% of the volume of the cavity 20, preferably 2% to 15%, more preferably 10%. What should be considered about the amount of heat medium 50 is cost and heat transfer efficiency. Any amount of heat medium 50 in the cavity 30 should still be within the scope of the present invention. The heat medium is a highly volatile material, and may be, for example, ether, alcohol, benzine or a mixture thereof or other suitable material.

加熱装置６０は、電気ヒーターであるが、筐体２０の底部に取り付けられている。
図３に示されているように、冷水管１１は配水管４０の第１接続端部４１に接続されており、温水管１２は配水管４０の第２接続端部４２に接続されている。電力線（不図示）は、加熱装置６０に接続されている。加熱装置６０は、電力制御のためのコントローラ（不図示）と、温度制御のための温度センサー（不図示）と、水を流したり止めたりするための流量センサー（不図示）とが設けられていてもよい。上記の制御装置は、従来の湯沸かし器に普通のものであるので、ここでは詳細は説明しない。筐体２０内の熱媒体５０を加熱するために加熱装置６０にエネルギーが入力されると、熱媒体５０は迅速に蒸発し、熱媒体５０の蒸気が空洞部３０に充満して配水管４０内の水を加熱する。明らかに、配水管４０の加熱領域は、配水管４０の全表面と最大となり、熱効率を最大とするである。真空状態は、熱媒体５０の気化と関係する。空洞部３０の圧力が低いほど、熱媒体５０の気化が速くなり、熱効率が高くなる。本発明は、蒸発した熱媒体を水への熱伝達用の媒体となるように提供するものであり、この結果、蒸発した熱媒体は熱を伝達するために空洞部全体に達する。これが、本発明の加熱効率がより高く、水を迅速に加熱する理由である。熱を伝達した後、液化した熱媒体５０は、筐体２０の内壁に沿って流れて空洞部３０の底部へ戻り、再び蒸発するように加熱装置６０で再加熱され、配水管内の水が所望の温度に迅速に加熱され、第２接続端部４２を通って温水管１２を流れ出ることができるようにする。 The heating device 60 is an electric heater, but is attached to the bottom of the housing 20.
As shown in FIG. 3, the cold water pipe 11 is connected to the first connection end 41 of the water distribution pipe 40, and the hot water pipe 12 is connected to the second connection end 42 of the water distribution pipe 40. A power line (not shown) is connected to the heating device 60. The heating device 60 is provided with a controller (not shown) for power control, a temperature sensor (not shown) for temperature control, and a flow rate sensor (not shown) for flowing and stopping water. May be. Since the above-described control device is common to conventional water heaters, details are not described here. When energy is input to the heating device 60 in order to heat the heat medium 50 in the housing 20, the heat medium 50 quickly evaporates, and the vapor of the heat medium 50 fills the cavity 30, and the inside of the water distribution pipe 40. Heat the water. Apparently, the heating area of the water distribution pipe 40 is the maximum with the entire surface of the water distribution pipe 40, and the thermal efficiency is maximized. The vacuum state is related to the vaporization of the heat medium 50. The lower the pressure in the cavity 30, the faster the heat medium 50 is vaporized and the higher the thermal efficiency. The present invention provides the evaporated heat medium to be a medium for heat transfer to water. As a result, the evaporated heat medium reaches the entire cavity for transferring heat. This is the reason why the heating efficiency of the present invention is higher and water is heated quickly. After transferring the heat, the liquefied heat medium 50 flows along the inner wall of the casing 20 and returns to the bottom of the cavity 30 and is reheated by the heating device 60 so as to evaporate again. So that the hot water pipe 12 can flow out through the second connection end 42.
