Description
本發明是關於冷熱水混合水龍頭，特別是關於將從熱水供給源供給的熱水和從冷水供給源供給的冷水所混合而成的冷熱水混合水予以吐出、阻止之冷熱水混合水龍頭。 The present invention relates to a hot and cold water mixing faucet, and more particularly to a hot and cold water mixing faucet that discharges and blocks hot and cold water mixed water obtained by mixing hot water supplied from a hot water supply source and cold water supplied from a cold water supply source.
以往，作為將從熱水供給源供給的熱水和從冷水供給源供給的冷水所混合而成的冷熱水予以吐出、阻止之冷熱水混合水龍頭，例如專利文獻1所記載，將冷熱水混合閥和流量調整閥直接***並收納於水龍頭主體內的構造是已知的。此外，在收納著冷熱水混合閥及流量調整閥的狀態下之水龍頭主體內的壁面等，確保熱水、冷水之複雜的流路。 In the related art, a hot and cold water mixing faucet that discharges and blocks hot and cold water which is obtained by mixing hot water supplied from a hot water supply source and cold water supplied from a cold water supply source, for example, is described in Patent Document 1, and a hot and cold water mixing valve is used.

然而，上述習知的冷熱水混合水龍頭，一般而言水龍頭主體是鑄模成形品，在製造時，為了對水龍頭主體形成熱水、冷水的複雜的內部流路必須使用特殊鑄模進行鑄模成形，必須在水龍頭主體的內壁等實施特別的機械加工等，因此存在製造效率低的問題。 However, in the above-mentioned conventional hot and cold water mixing faucet, in general, the faucet main body is a molded product, and in order to form a complicated internal flow path for forming hot water and cold water to the faucet main body, a special mold must be used for molding, and must be Since the inner wall of the faucet main body or the like is subjected to special machining or the like, there is a problem that manufacturing efficiency is low.
此外，為了在水龍頭主體確保熱水、冷水之複雜的流路，水龍頭主體的外形尺寸(例如，水龍頭主體的外徑等)變大而造成設計性降低，因水龍頭主體的重量增加而造成製造成本上昇。 In addition, in order to ensure a complicated flow path of hot water and cold water in the faucet main body, the outer dimensions of the faucet main body (for example, the outer diameter of the faucet main body, etc.) become large, resulting in a decrease in design, and the manufacturing cost is increased due to the weight of the faucet main body. rise.
再者，近年，按照國內外之各種設置狀況，所要求之冷熱水混合水龍頭的規格會有不同的情況。例如，依設置狀況，可能使用冷熱水混合水龍頭之長度方向的外形尺寸比通常的規格更長的規格、或使用冷熱水混合水龍頭之熱水流入口和冷水流入口的軸心間距離(冷熱水混合水龍頭之熱水流入口的中心軸線和冷水流入口的中心軸線之距離)比通常的規格更長的規格等，在這些情況，從水龍頭主體的熱水流入口及冷水流入口各個到水龍頭主體的排出口之內部流路的路徑變複雜，路徑長度也變長，用於確保如此般的內部流路的製造成本也更為增加。 Furthermore, in recent years, according to various installation conditions at home and abroad, the specifications of the required hot and cold water mixing faucets may be different. For example, depending on the setting, it is possible to use a specification in which the length direction of the hot and cold water mixing faucet is longer than a normal specification, or a distance between the hot water inlet and the cold water inlet of the hot and cold water mixing faucet (cold and hot water mixing) The distance between the central axis of the hot water inlet of the faucet and the central axis of the cold water inlet is longer than the normal specification. In these cases, from the hot water inlet and the cold water inlet of the faucet main body to the discharge port of the faucet main body. The path of the internal flow path becomes complicated, and the path length also becomes long, which is used to ensure that the manufacturing cost of such an internal flow path is also increased.
因此，如何將水龍頭主體的內部流路做成簡單的路徑成為被要求的課題。 Therefore, how to make the internal flow path of the faucet main body into a simple path becomes a required problem.
此外，在上述習知的冷熱水混合水龍頭，因為水龍頭主體是鑄模成形品，特別是在水龍頭主體之熱水側區域的表面、混合冷熱水之排出口附近的表面，通過內部之熱水 溫度的熱會傳過來，可能會熱到使用者無法接觸表面的程度，如何將水龍頭主體的設計性提高，並確保用於避免水龍頭主體的表面變熱而讓冷水通過之冷水通路等的內部流路，也成為被要求的課題。 Further, in the above-mentioned conventional hot and cold water mixing faucet, since the faucet main body is a molded article, particularly on the surface of the hot water side region of the faucet main body, the surface near the discharge port of the mixed hot and cold water, the hot water through the inside The heat of the temperature will be transmitted, which may be so hot that the user cannot touch the surface, how to improve the design of the faucet body, and ensure the internal flow of the cold water passage for preventing the surface of the faucet from heating and letting the cold water pass. Road has also become a subject of demand.
於是，本發明是為了解決上述習知技術的問題、被要求的課題而開發完成者，其目的是為了提供一種冷熱水混合水龍頭，藉由將水龍頭主體的內部流路做成簡單的路徑而使水龍頭主體的外形尺寸變得小型化，並將設計性提高。 Accordingly, the present invention has been made in order to solve the problems of the above-described prior art and the problems to be solved, and an object thereof is to provide a hot and cold water mixing faucet by making a simple path of the internal flow path of the faucet body.

此外，利用流量調整閥殼體，在水龍頭主體和流量調整閥殼體之間之水龍頭主體的排出口的附近也形成有冷水通路，因此可成為縱使使用者接觸水龍頭主體的表面也不會感到熱之冷熱水混合水龍頭。 Further, with the flow regulating valve housing, a cold water passage is formed in the vicinity of the discharge port of the faucet main body between the faucet main body and the flow regulating valve housing, so that the user does not feel hot even when the user touches the surface of the faucet main body.

The direction flows into the valve member 48 of the flow regulating valve unit 12, and then flows out from the outlet of the valve seat member 46 in the radial direction of the valve member 48 and the valve seat member 46 via the respective openings 48a, 48b of the valve member 48, and flows from the flow rate. Adjusting the flow of valve unit 12 Ports 46a, 46b directly overlap the faucet body 2 in respective outlets 26a, 32a to each of the discharge passage 26, 32 flows out.
此外，藉由使流量調整閥單元12之冷熱水混合水的流入流路52和流出流路互相正交，從流量調整閥單元12的各流出口46a，46b到水龍頭主體2的各排出口26a，32a之下游側的流路不須設置於水龍頭主體2，能使水龍頭主體2更為小型化。 Further, by causing the inflow flow path 52 and the outflow flow path of the hot and cold water mixed water of the flow rate adjusting valve unit 12 to be orthogonal to each other, from the respective outflow ports 46a, 46b of the flow rate adjusting valve unit 12 to the respective discharge ports 26a of the faucet body 2. The flow path on the downstream side of 32a does not need to be provided in the faucet body 2, and the faucet body 2 can be further miniaturized.
再者，依據本實施形態的冷熱水混合水龍頭1，使水龍頭主體2之出水部吐水用的吐水口26b之中心 軸線A1及淋浴吐水用的排出口32a之中心軸線A2，通過水龍頭主體2的熱水流入口20之中心軸線A3和水龍頭主體2的冷水流入口22之中心軸線A4的中間，藉此，將水龍頭主體2的熱水流入口20及水流入口22分別配置成，離水龍頭主體2之包含出水部吐水用的吐水口26b之出水部24及包含淋浴吐水用的排出口32a之淋浴軟管連接管30各個的距離大致相等，因此可將冷熱水混合水龍頭1的設計性提高，不管是從冷熱水混合水龍頭1之長度方向的兩端之任一側，使用者都容易接近水龍頭主體2之出水部24及淋浴軟管連接管30各個。 Further, according to the hot and cold water mixing faucet 1 of the present embodiment, the center of the spouting port 26b for spouting the water outlet portion of the faucet body 2 is provided. The axis A1 and the center axis A2 of the shower spout 32a pass through the center axis A3 of the hot water inlet 20 of the faucet body 2 and the center axis A4 of the cold water inlet 22 of the faucet body 2, whereby the faucet body is The hot water inlet 20 and the water inlet 22 of the faucet body 2 are disposed so as to be separate from the water outlet portion 24 of the faucet body 2 including the water discharge port 26b for discharging the water in the outlet portion, and the shower hose connecting tube 30 including the discharge port 32a for shower spouting. Since the distances are substantially equal, the design of the hot and cold water mixing faucet 1 can be improved, and the user can easily access the water outlet portion 24 of the faucet body 2 and the shower from either side of the longitudinal direction of the hot and cold water mixing faucet 1. The hose connection pipes 30 are each.
此外，依據本實施形態的冷熱水混合水龍頭1，藉由使水龍頭主體2之淋浴吐水用的排出口32a之中心軸線A2通過水龍頭主體2的長度方向的中心O1，使供連接淋浴軟管28之冷水龍頭主體2的淋浴軟管連接管30形成於離水龍頭主體2之長度方向的兩端部距離相等的位置，因此可將冷熱水混合水龍頭1的設計性提高，不管是從冷熱水混合水龍頭1之長度方向的兩端的任一側，使用者都容易接近水龍頭主體2之淋浴軟管連接管30。 Further, the hot and cold water mixing faucet 1 according to the present embodiment is configured to connect the shower hose 28 by passing the center axis A2 of the discharge port 32a for shower discharge of the faucet body 2 through the center O1 of the longitudinal direction of the faucet body 2. The shower hose connecting pipe 30 of the cold water faucet main body 2 is formed at a position equal to the distance between both end portions in the longitudinal direction of the faucet main body 2, so that the design of the hot and cold water mixing faucet 1 can be improved, regardless of whether the hot and cold water mixing faucet 1 is used. The shower hose connecting pipe 30 of the faucet body 2 is easily accessible to the user on either side of the longitudinal direction.
