Description

具可調節水溫及降低熱損之電熱水器系統 Electric water heater system with adjustable water temperature and reduced heat loss
本發明一種具可調節水溫及降低熱損之電熱水器系統,詳指應用於家電領域之技術,其主要技術在於,能夠以最精準的感應而生成最合適的水溫,進而提供最適當的溫度給予使用者洗滌使用,極為一種實用性極佳之發明。 The present invention is an electric water heater system with adjustable water temperature and reduced heat loss. It refers in detail to the technology applied in the field of household appliances. The main technology is that it can generate the most suitable water temperature with the most accurate induction, and then provide the most suitable The temperature can be used by the user for washing, which is an invention with excellent practicality.
每日辛苦工作回家後除了享受美食與適當的休息外,最享受的部分就是洗澡,利用水將身上的疲憊洗去,徹底的讓身體得到放鬆,而在洗澡上最重要的部分就是適當的水溫,每個人對於水溫的感覺都不盡相同,但如何才可得到適合的水溫才是許多使用者最要求的技術,市面上大多數以兩種方式給予適當的水溫,其一為傳統的瓦斯桶配合水龍頭撥轉,但此方式有個缺失在於,無法調整到最佳的溫度,水龍頭的撥轉過多其水溫就變冷,可是撥轉過少就會變燙,因此傳統的瓦斯桶使用已經逐漸淘汰;其二則是使用越來越普遍的電熱水器,電熱水器主要是透過內部所安裝的溫度控制器控制儲水桶內的水溫,使用者基於現存儲水桶內之溫度對水龍頭做調整進行洗滌。 After going home from hard work every day, in addition to enjoying food and proper rest, the most enjoyable part is taking a bath. Use water to wash away the exhaustion and completely relax the body. The most important part of taking a bath is proper Water temperature, everyone’s perception of water temperature is different, but how to get the right water temperature is the most requested technology for many users. Most people on the market give the right water temperature in two ways, one It is a traditional gas bucket with a faucet turning, but this method has a shortcoming that it cannot be adjusted to the best temperature. If the faucet is turned too much, the water temperature will become cold, but if it is turned too little, it will become hot. Therefore, the traditional The use of gas buckets has been gradually eliminated; the second is the use of more and more common electric water heaters. Electric water heaters mainly control the water temperature in the water storage bucket through an internal temperature controller. The user is based on the temperature in the current storage bucket. The faucet is adjusted for washing.
然而,上述的電熱水器雖然比起傳統瓦斯桶更能夠產生最合適的水溫,可是電熱水器也存在幾項問題,首先電熱水器會 連接有儲水桶提供眾多使用,但此所產生的問題在於,當儲水桶內的水一經使用後,電熱水器必須馬上進行補水加熱,但熱出冷進的方式下會逐漸造成儲水桶內溫度下降,簡單來說排出五公升的熱水就必須補充五公升的冷水,而重新對五公升的冷水再加熱所需要的電熱耗能極高,且也會衍生使用者如果還需用水時就必須耗費時間等待冷水加熱完成才可繼續使用。另外由於儲水桶內溫度持續下降,使用者為了維持穩定的出水溫度需要不斷調整水龍頭方可達到其所需之溫度。 However, although the above-mentioned electric water heater can produce the most suitable water temperature better than traditional gas barrels, there are several problems with electric water heaters. The water storage bucket is connected to provide many uses, but the problem that arises is that once the water in the water storage bucket is used, the electric water heater must be refilled and heated immediately, but the hot out and cold in mode will gradually cause the temperature in the water storage bucket to drop In simple terms, to discharge five liters of hot water, five liters of cold water must be added, and reheating five liters of cold water requires extremely high electrical energy consumption, and it will also cost users if they still need water. Time to wait for the cold water to heat up before you can continue to use it. In addition, because the temperature in the water storage bucket continues to drop, users need to constantly adjust the faucet to reach the desired temperature in order to maintain a stable water outlet temperature.

本發明主要目的在於,提供使用者在需要溫水的時候才開啟水溫的感應並進行冷水、熱水的混合,藉此可以節省水的支出,也可以節省電力的消耗,讓使用者於使用時能夠以最合適的水溫進行洗滌,其改善習知的電熱水器在水溫控制的操作上,除了傳統無法有效調整到所要的水溫外,手動調整的方式容易造成感溫不夠精準,導致所產生的水溫的不符合使用者的需求,必須耗費時間、電力、水來等待水溫的調整改變等缺失,故為了達到上述所說的功效並改善習知的缺失,本發明一種具可調節水溫及降低熱損之電熱 水器系統,主要與冷水管路、熱水管路相連通,其包括:一電熱水器,其熱水管路的一端係連接於該電熱水器;一控制閥體,其包含一主閥座、一封蓋及一分流器,該主閥座包含有一主殼部及一進水部,該主殼部一端內凹形成一混水槽室,並於該混水槽室底部設有一出水口,而該進水部包含一冷進管、一熱進管及一混水管,該混水管一端連通於混水槽室,又該熱進管係連接熱水管路的另一端,另外該分流器設有一第一分水管、一第二分水管及一進水管,該進水部的冷進管係連接於分流器的第一分水管或第二分水管,而該第一分水管或第二分水管的另一管則連接於電熱水器,又冷水管路係連接於該分流器的進水管,另外該封蓋係裝設於主殼部設有混水槽室的一側並予以封阻,而該封蓋對應混水槽室的一側進一步樞設一擺塊,另外在該封蓋內部設有一磁控件,冷水管路的冷水及熱水管路的熱水流經混水管後流向混水槽室並沖動擺塊;及一流量閥桿,其一端裝設於混水管內另一端則凸露於混水管外,該流量閥桿外露於混水管外的一端係連結一馬達,該馬達係與封蓋內部的磁控件電性連結,又該流量閥桿位於混水管內的一端之端面內凹一混水管道,而在該流量閥桿的外周側開設一入水口連通混水管道;其中,冷水管路的冷水流經分流器後,其一部分直接進入電熱水器內進行加熱,另一部分的冷水則流入進水部的冷進管與熱水管路所流入熱進管的熱水予以混合,又冷水與熱水經由入水口流入混水管道後再經由混水管流出至混水槽室,當混合的水流入混水槽室時係沖動擺塊,而該擺塊係與磁控件相互磁吸後即可啟動馬達的運作並控制流 量閥桿進行樞轉,藉此控制入水口的旋轉位置而調整冷水、熱水的流量比例。 The main purpose of the present invention is to provide users with water temperature sensing and mixing of cold water and hot water when they need warm water, thereby saving water expenditure and power consumption, allowing users to use When washing with the most suitable water temperature, it improves the water temperature control operation of the conventional electric water heater. In addition to the traditionally unable to effectively adjust the required water temperature, the manual adjustment method may easily cause insufficient temperature sensing, resulting in The generated water temperature does not meet the needs of the user, and it takes time, electricity, and water to wait for the adjustment and change of the water temperature.

根據上述對於本發明所界定的主要技術,其優點在於,利用分流器的設置將冷水管路之水流予以分流下,得以減緩電熱水器在供應熱水後之補水時的熱損失,讓電熱水器在加熱上不需要耗費過多的電能進行冷水加熱;此外透過在封蓋裝設的擺塊及磁控件的設置,當冷水及熱水的混合沖向混水槽室沖擊擺塊,藉此啟動磁控件控制馬達開始運作,又該馬達的運作得以控制流量閥桿進行樞轉,該流量閥桿的樞轉可以控制冷水與熱水的流量進而混合出所要的水溫,反之當關閉冷水、熱水的使用時,該擺塊無受到混合之水沖擊時,該流量閥桿則不會進行樞轉也就不會隨時進行水溫的改變,以便於下次啟動時水溫控制能夠較為精準。可見本案可說是一種相當具有實用性及進步性之發明,相當值得產業界來推廣,並公諸於社會大眾。 According to the above-mentioned main technology defined for the present invention, its advantage is that the water flow of the cold water pipeline is divided by the setting of the diverter, which can reduce the heat loss of the electric water heater when the water is supplied after the hot water is supplied. Heating does not need to consume too much electricity for cold water heating; in addition, through the setting of the pendulum block and magnetic control installed on the cover, when the mixture of cold water and hot water rushes to the mixing tank chamber to impact the pendulum block, the magnetic control control is activated The motor starts to operate, and the operation of the motor can control the flow valve stem to pivot. The pivot of the flow valve stem can control the flow of cold water and hot water to mix the desired water temperature. On the contrary, turn off the use of cold water and hot water. When the pendulum block is not impacted by the mixed water, the flow valve stem will not pivot and will not change the water temperature at any time, so that the water temperature control can be more accurate at the next startup. It can be seen that this case can be said to be a very practical and progressive invention, which is worthy of being promoted by the industry and made public.

根據上述對於本發明之說明,請參閱第二、五、六、七圖所示,並參考第六圖的箭頭方向(為冷水管路(10)、熱水管路(20)的水流方向)、第七圖的箭頭方向(細箭頭為混水後的水流方向、粗箭頭為擺塊(3)的擺動方向),一般習知的電熱水器在進行使用時,以實際的方式舉例說明,當家庭有五人需要洗澡時,電熱水器所產生的水量有限大約僅能提供三人使用時,剩下的二人就必須等待冷水 經由電熱水器的加熱補充後才可繼續使用,但是冷水的水量補充還是以五人的使用為主,因此電熱水器必須耗費更多時間進行加熱,以至於時間、電力的消耗過長也過大,且如果剩下的二人持續使用的話,那只會造成電熱水器加熱的速度不夠快,導致水溫無法達到一定的熱度,此行為無疑的也是讓電熱水器、熱水管路內的熱量損失,長期的使用下會加速電熱水器內的零件耗損,電費也會隨之飆高,所以說本發明利用了分流器(23)的設置將冷水管路(10)所提供的冷水水量予以分流,使得進入電熱水器(1)內的冷水水量降低,冷水水量減少下電熱水器(1)也就無需使用過多的電能進行加熱,且冷水水量較少其加熱變熱的速度可以較快,如此也就不會造成電熱水器(1)、熱水管路(20)的熱量損失;本發明採用了擺塊(3)及磁控件(4)的配合,當冷水管路(10)、熱水管路(20)開啟水的流進時,冷水及熱水的混合會沖動擺塊(3),該擺塊(3)的擺動會與磁控件(4)進行磁控感應進而啟動馬達(6)開啟運作,該馬達(6)的運作即可開始控制流量閥桿(5)進行樞轉,該流量閥桿(5)的樞轉即可控制冷水、熱水混合的水量比例,如此一來即可快速達到所設定之水溫使用,反之當冷水、熱水為關閉時,該擺塊(3)則無法與磁控件(4)磁控感應而開啟馬達(6),以至於該流量閥桿(5)維持在固定位置不會隨意樞轉,使得殘留於混水槽室(213)內的水溫維持在定值,如此一來下次的操作使用即可從穩定的溫度判斷下調整流量閥桿(5)進行樞轉而快速的調整至所設定的水溫,不耗費時間也不會浪費過多的水量。 According to the above description of the present invention, please refer to the second, fifth, sixth and seventh diagrams, and refer to the arrow direction of the sixth diagram (the direction of the water flow in the cold water pipe (10) and the hot water pipe (20)), The arrow direction in the seventh figure (the thin arrow is the water flow direction after mixing, the thick arrow is the swing direction of the pendulum block (3)). When the conventional electric water heater is in use, it is illustrated in a practical way. When five people need to take a bath, the amount of water produced by the electric water heater is limited. When only three people can use it, the remaining two people have to wait for cold water The electric water heater can only continue to be used after it is refilled by heating. However, the amount of cold water replenishment is mainly used by five people. Therefore, the electric water heater must take more time to heat, so that the time and electricity consumption is too long and too large, and If the remaining two people continue to use it, it will only cause the electric water heater to heat up fast enough, causing the water temperature to fail to reach a certain degree of heat. This behavior is undoubtedly also the heat loss in the electric water heater and the hot water pipe, which will be long-term The use of the electric water heater will accelerate the loss of parts in the electric water heater, and the electricity bill will also increase accordingly.
