従来、浴槽と給湯機とが配管接続されて、湯はり処理や追い焚き処理を行うようにした浴槽システムが周知である。この浴槽システムにおいては、浴槽の側壁に貫通状態に温水口装置が取り付けられるとともに、この装置と室外の給湯機とが配管接続されている。そして、湯はり時には、給湯機から供給された温水を温水口装置を介して浴槽内に導入するとともに、追い焚き時には、槽内の温水を温水口装置から吸い込んで給湯機に送り込み、そこで再加熱した後、槽内に戻すようにしている。 2. Description of the Related Art Conventionally, a bathtub system in which a bathtub and a water heater are connected by piping so as to perform hot water processing and reheating processing is well known. In this bathtub system, a hot water outlet device is attached in a penetrating manner to the side wall of the bathtub, and this device and an outdoor water heater are connected by piping. When hot water is poured, hot water supplied from the water heater is introduced into the bathtub through the hot water port device, and when reheating, the hot water in the tank is sucked from the hot water port device and sent to the hot water device, where it is reheated. After that, it returns to the tank.
このような浴槽システムに用いられる温水口装置としては、例えば下記特許文献1に示すものが周知である。この温水口装置は、浴槽内側に突出するように配置される浴槽内突出部を具備し、この浴槽内突出部の内部には、第1及び第2区画室が設けられている。更に浴槽内突出部の前面側に第1及び第2吸込口が設けられるとともに、浴槽内突出部の周側面に第1及び第2吐出口が設けられている。また温水口装置の内部には、浴槽の内外を連通する第1及び第2流路を有している。そして、室外給湯機に接続される外部戻り管が、例えば第1流路に接続されるとともに、給湯機側の外部往き管が、第2流路に接続されている。この構成において、湯はり時には、外部往き管及び戻り管から供給される温水が第1及び第2流路を通って、第1及び第2区画室内に導入されて、第1及び第2吐出口から浴槽内に供給される一方、追い炊き時には、外部往き管から供給される温水が第2流路を通って第2区画室内に導入されて、第2吐出口から浴槽内に供給されるとともに、第1吸込口から第1区画室内に吸い込まれた低温の浴槽水が第1流路を通って外部戻り管から室外給湯機に送り込まれることにより、浴槽水が強制的に循環されるよう構成されている。
しかしながら、上記従来の浴槽用温水口装置においては、追い炊き時に温水を循環させる際に、例えば浴槽内に浮遊するゴミ、特に毛髪等が、温水と共に吸込口から区画室内に吸い込まれ、更に区画室から温水経路に吸い込まれて、温水口装置内部や給湯機内に入り込み、装置内部に流路詰まりが生じてしまい、給湯性能を低下させてしまうという問題が発生する。 However, in the conventional hot-water port device for a bathtub, when circulating hot water at the time of additional cooking, for example, dust, especially hair, etc. floating in the bathtub is sucked into the compartment with the hot water from the suction port. Then, the water is sucked into the hot water passage and enters the hot water inlet device or the hot water heater, causing a problem that the flow passage is clogged in the device and the hot water supply performance is deteriorated.
この発明は、上記従来技術の問題を解消し、毛髪等の異物が装置内部に浸入するのを確実に防止できて、安定した給湯性能を長期間維持することができる浴槽用温水口装置を提供することを目的とする。 This invention solves the above-mentioned problems of the prior art, and provides a hot water outlet device for a bathtub that can reliably prevent foreign substances such as hair from entering the inside of the device and can maintain stable hot water supply performance for a long period of time.

The flow path on the side connected to the discharge pipe functions as a discharge path, and the flow path on the side connected to the return pipe functions as a suction flow path to perform forced circulation. For example, when the first flow path (A) is connected by piping so that the second flow path (B) is a suction flow path and the second flow path (B) is a discharge flow path, the hot water supplied from the water heater is the second flow path ( B), passing through the second communication hole (51b), further upstream region (58b), second filter (7b), downstream region (58b), second warm water channel (54b) of the second compartment (5b). ) Through the second hot water port (6b).
また第1流路(A)側の吸込流路においては、室外給湯機の戻り管及び第1流路(A)の負圧に伴い、第1区画室(5a)が負圧となる。従って、浴槽(T)内の温水(浴槽水)は、第1温水口(6a)、第1温水口流路(54a)を通って、第1区画室(5a)の下流域(59a)に流入される。更にその温水は、第1フィルター(7a)、第1区画室上流域(58a)、第1連通孔路(51a)、第1流路(A)、第1外管接続部(1a)を通って室外給湯機に戻される。こうして浴槽(T)と室外給湯機との間で温水が循環されることにより、追い炊き処理が行われる。 Moreover, in the suction flow path by the side of the 1st flow path (A), a 1st division chamber (5a) becomes a negative pressure with the return pipe of an outdoor water heater, and the negative pressure of a 1st flow path (A). Accordingly, the hot water (tub water) in the bathtub (T) passes through the first hot water port (6a) and the first hot water port channel (54a) to the downstream area (59a) of the first compartment (5a). Inflow. Furthermore, the hot water passes through the first filter (7a), the first compartment upstream area (58a), the first communication hole (51a), the first flow path (A), and the first outer pipe connection (1a). Returned to the outdoor water heater. In this way, the hot water is circulated between the bathtub (T) and the outdoor water heater, whereby the additional cooking process is performed.
この温水循環時において、浴槽(T)から室外給湯機に吸引される温水は、第1温水口(6a)から第1区画室下流域(59a)を通って、更に第1フィルター(7a)を通過するものであるため、そのフィルター(7a)によって、吸い込まれる温水内のゴミ等の異物、不純物が取り除かれる。従って、温水口装置(P)の内部、戻り管等の外管、室外給湯機の内部に、ゴミ等が侵入することがなく、その侵入による不具合を確実に防止することができる。 During this hot water circulation, the hot water sucked into the outdoor water heater from the bathtub (T) passes through the first compartment (6a) through the first compartment downstream area (59a), and further passes through the first filter (7a). Since it passes through, the filter (7a) removes foreign matters such as dust in the hot water and impurities. Accordingly, dust or the like does not enter the hot water port device (P), the outer pipe such as the return pipe, or the outdoor water heater, so that it is possible to reliably prevent problems caused by the intrusion.
また第1温水口(6a)から吸い込まれた毛髪等のゴミが、仮にフィルター(7a)を通過したとしても、その毛髪等は装置内部に浸入することはない。すなわちフィルター(7a)を通過して第1区画室上流域(58a)に流入した毛髪等は、吸水に伴って、第1連通孔路(51a)を通って第1流路(A)へと浸入しようとするが、その毛髪等は、第1連通孔路(51a)の屈曲部(凹陥部底部)に滞留し、第1流路(A)への浸入を防止することができる。しかも、第1連通孔路(51a)の他端開口(522a)には、縦縞状に複数の桟部材(530a)が設けられているため、毛髪等はこの桟部材(530a)に絡み付いて係止することによっても、第1流路(A)への浸入を確実に防止することができる。従って、浴槽内に浮遊する毛髪等が、装置(P)の内部や、戻り等の外管、室外給湯機の内部に浸入することがなく、その浸入による不具合をより確実に防止できて、長期間安定した給湯性能を維持することができる。 Even if dust such as hair sucked from the first hot water port (6a) passes through the filter (7a), the hair or the like does not enter the inside of the apparatus. That is, the hair or the like that has flowed into the first compartment upstream area (58a) through the filter (7a) passes through the first communication hole path (51a) to the first flow path (A) with water absorption. Although trying to enter, the hair or the like stays in the bent portion (bottom portion of the recessed portion) of the first communication hole channel (51a), and can prevent the first channel (A) from entering. In addition, since the other end opening (522a) of the first communication hole (51a) is provided with a plurality of crosspiece members (530a) in the form of vertical stripes, hair or the like is entangled with the crosspiece member (530a). By stopping, the intrusion into the first flow path (A) can be reliably prevented. Therefore, the hair floating in the bathtub does not enter the inside of the device (P), the outer pipe of the return, the inside of the outdoor water heater, etc. A stable hot water supply performance can be maintained for a period of time.
なお本実施形態において、温水口装置(P)の2つの流路(A)(B)を、室外給湯機の往き管及び戻り管に対し、上記とは逆に接続した場合には、各流路(A)(B)を温水が上記とは逆方向に流通することにより、不具合なく強制循環されるものである。この場合においても、第2温水口(6b)から吸い込まれた毛髪等のゴミが、たとえフィルター(7b)を通過したとしても、その毛髪等は、上記と同様に装置内部に浸入することはない。すなわちフィルター(7b)を通過して第2区画室上流側(58b)に流入した毛髪等は、吸水に伴って、第2連通孔路(51b)を通って第2流路(B)へと浸入しようとするが、その毛髪等は、第2連通孔路(51b)の屈曲部(凹陥部底部)に滞留し、第2流路(B)への浸入を防止することができる。しかも第2連通孔路(51b)の他端開口(522b)には、縦縞状に複数の桟部材(530b)が設けられているため、毛髪等はこの桟部材(530b)に絡み付いて係止することによっても、第2流路(B)への浸入を確実に防止することができる。従って、浴槽内に浮遊する毛髪等が、装置(P)の内部や、外管、室外給湯機の内部に浸入することがなく、その浸入による不具合をより確実に防止できて、長期間安定した給湯性能を維持することができる。 In this embodiment, when the two flow paths (A) and (B) of the hot water outlet device (P) are connected to the forward pipe and the return pipe of the outdoor water heater in the opposite manner, When hot water flows through the paths (A) and (B) in the direction opposite to the above, it is forcedly circulated without any problems. Even in this case, even if dust such as hair sucked from the second hot water port (6b) passes through the filter (7b), the hair or the like does not enter the inside of the apparatus as described above. . That is, the hair or the like that has flowed into the second compartment upstream (58b) through the filter (7b) passes through the second communication hole (51b) to the second flow path (B) due to water absorption. Although trying to enter, the hair or the like stays in the bent portion (the bottom of the recessed portion) of the second communication hole channel (51b), and can prevent entry into the second channel (B). In addition, since the other end opening (522b) of the second communication hole (51b) is provided with a plurality of crosspiece members (530b) in the form of vertical stripes, hair or the like is entangled and locked to the crosspiece member (530b). By doing so, it is possible to reliably prevent entry into the second flow path (B). Therefore, hair that floats in the bathtub does not enter the inside of the device (P), the outer pipe, or the outdoor water heater, and it is possible to prevent problems caused by the invasion more reliably and to be stable for a long time. Hot water supply performance can be maintained.
また本実施形態の浴槽用温水口装置(P)においては、貯湯時には第1及び第2温水口(6a)(6b)を吐出口として利用し、追い炊き時にはいずれか一方の温水口を吸込口として利用するものである。このように温水口(6a)(6b)を、吐出用及び吸込用の双方に兼用させるものであるため、温水口(6a)(6b)と、区画室(5a)(5b)等の流通経路との位置関係や接続関係を簡素に形成することができる上更に、温水口(6a)(6b)に逆流防止用の逆止弁を設ける必要もない。このため、構造の簡素化及び部品点数の削減を図ることができ、小型軽量化はもちろん、コストの削減も図ることができる。 Moreover, in the hot-water port apparatus (P) for bathtubs of this embodiment, the 1st and 2nd hot-water port (6a) (6b) is utilized as a discharge port at the time of hot water storage, and either hot-water port is a suction port at the time of additional cooking It is intended to be used as Since the hot water ports (6a) and (6b) are used for both discharge and suction as described above, distribution channels such as the hot water ports (6a) and (6b) and the compartments (5a and 5b) are provided. In addition, it is not necessary to provide a check valve for preventing backflow at the hot water ports (6a) and (6b). Therefore, the structure can be simplified and the number of parts can be reduced, and the cost can be reduced as well as the size and weight can be reduced.
特に本実施形態においては、区画室部材(50)を、ほぼ左右対称形状に形成することができ、より一層構造の簡素化を図ることができる。 In particular, in this embodiment, the compartment member (50) can be formed in a substantially bilaterally symmetric shape, and the structure can be further simplified.
参考までに、本実施形態の浴槽用温水口装置(P)においては、従来の温水口装置に対し、浴槽内突出部としての区画室部材(50)における突出寸法を小さくすることができる。 For reference, in the hot water outlet device (P) for bathtubs of this embodiment, the protruding dimension in the compartment member (50) as the protruding portion in the bathtub can be made smaller than the conventional hot water outlet device.
また本実施形態においては、温水流通経路を簡素にできるため、温水の流通抵抗を低減できるとともに、逆止弁等の抵抗手段がなく、圧力損失も低減できるため、温水を高圧で効率良く流通させることができる。このため特に追い炊き時等においては、浴槽内に強い圧力で温水を吐出させることができ、浴槽内における温水の循環を効率良く行うことができ、入浴時における温度分布の偏り等の不具合を有効に防止することができる。 Further, in this embodiment, since the hot water flow path can be simplified, the hot water flow resistance can be reduced, there is no resistance means such as a check valve, and the pressure loss can be reduced, so that the hot water can be circulated efficiently at high pressure. be able to. For this reason, hot water can be discharged into the bathtub with a strong pressure, especially during additional cooking, etc., and the hot water can be circulated efficiently in the bathtub, effectively eliminating problems such as uneven temperature distribution during bathing. Can be prevented.
更に本実施形態においては、区画室部材(50)の両側に温水口(6a)(6b)を設けて、追い炊き時には、一方の温水口(6a)を介して一側方に向けて温水を吐出させて、他方の温水口(6b)を介して他側方から温水を吸い込むようにしているため、温水口(6a)から吐出された温水が、浴槽内を循環せずに他方の温水口(6b)から吸い込まれるようなショートサイクル等の不具合を防止でき、温水を浴槽内において大きく循環させることができ、この点においても、浴槽内の温度分布の偏り等を、より確実に防止することができる。 Furthermore, in this embodiment, a hot water port (6a) (6b) is provided on both sides of the partition chamber member (50), and at the time of additional cooking, hot water is directed toward one side through one hot water port (6a). Since it is made to discharge and warm water is sucked in from the other side via the other warm water port (6b), the warm water discharged from the warm water port (6a) does not circulate in the bathtub, and the other warm water port (6b) can prevent problems such as a short cycle that is sucked in, and can circulate hot water in the bathtub greatly. Also in this respect, the temperature distribution in the bathtub can be more reliably prevented. Can do.
また本実施形態においては、湯はり時に温水が通過する区画室(5a)(5b)内にフィルター(7a)(7b)を設けるものであるため、追い炊き時の吸込経路上に配置される第2フィルター(7b)に不純物が付着したとしても、湯はり時にはフィルター(7b)に取り込まれた不純物を自動的に除去して清掃することができる。すなわち、湯はり時には、温水が第2フィルター(7b)が配置された第2区画室(5b)を、追い炊き時とは逆方向に流通するものであるため、この逆流によって第2フィルター(7b)に取り込まれた不純物が取り除かれて、温水口(5b)より浴槽内に放出される。このように湯はり時には、フィルター(7a)(7b)を逆流洗浄作用によって自動的に清掃することができ、メンテナンス作業を省略でき、又は少なくともメンテナンス作業を軽減でき、良好な使い勝手を得ることができる。 In the present embodiment, since the filters (7a) and (7b) are provided in the compartments (5a) and (5b) through which the hot water passes when hot water is poured, the first is arranged on the suction path at the time of additional cooking. Even if impurities adhere to the two filters (7b), the impurities taken into the filter (7b) can be automatically removed and cleaned during hot water pouring. That is, since hot water flows through the second compartment (5b), in which the second filter (7b) is arranged, in the opposite direction to that during additional cooking, the second filter (7b) ) Is removed and discharged into the bathtub from the hot water port (5b). Thus, when hot water is poured, the filters (7a) and (7b) can be automatically cleaned by the backwashing action, and maintenance work can be omitted, or at least maintenance work can be reduced, and good usability can be obtained. .
また本実施形態においては、フィルター清掃作業等を支障なく行うことができる。すなわち化粧カバー(9)の前面カバーに前面開口(95)を形成するとともに、区画部材(50)の区画室カバー(6)を透明な部材により構成しているため、開口(95)及び透明な区画室カバー(6)を介して、フィルター部材(7)を視認することができる。従って、フィルター(7a)(7b)の汚れ度合を容易に把握でき、必要時に、フィルター(7a)(7b)を清掃することができる。 Moreover, in this embodiment, filter cleaning work etc. can be performed without trouble. That is, since the front opening (95) is formed in the front cover of the decorative cover (9) and the compartment cover (6) of the partition member (50) is made of a transparent member, the opening (95) and the transparent cover are formed. The filter member (7) can be visually recognized through the compartment cover (6). Therefore, the degree of contamination of the filters (7a) and (7b) can be easily grasped, and the filters (7a) and (7b) can be cleaned when necessary.
また本実施形態においては、区画室部材(50)の周側面から浴槽内に温水を吐出するものであるため、貯湯時に、温水が浴槽内面に沿って滑らかに供給することができ、例えば吐出される温水の飛散による不快音の発生を防止でき、静かに湯はりを行うことができる。 In the present embodiment, since warm water is discharged into the bathtub from the peripheral side surface of the compartment member (50), the hot water can be smoothly supplied along the inner surface of the bathtub during hot water storage, for example, discharged. The generation of unpleasant noise due to splashing of warm water can be prevented, and the hot water can be poured gently.
