  In this state, the flow path forming member (3) is inserted into the cylinder (21) of the in-tank fitting (2) through the cylinder (41), and the inner cylinder (11) of the out-of-tank attachment (1) is inserted. ) To fit into the cylindrical hole. Then, the screw (37) is inserted into the screw insertion portion (66) (56) from the front side of the lid (6), and screwed into the boss (26) to be fixed.

  Thereafter, the filter member (9) is attached to the flow path forming member (3) and attached to complete the assembling work of the hot water port device (P) to the bathtub (T).

  In the hot water outlet device (P) assembled in the bathtub (T) in this manner, the pipe from the outdoor water heater is connected to the outer pipe connecting portion (1a) (1b) of the outdoor fitting (1). A system is formed.

  In this bathtub system, when hot water is supplied into the bathtub (T) to store hot water, the hot water is supplied to both of the two outer pipe connecting portions (1a) and (1b), and the two flow paths (A). Both (B) are used as discharge channels for supplying hot water to the bathtub (T). That is, when warm water flows into the two compartments (5a) and (5b) of the flow path forming member (3) through the flow paths (A) and (B), the valve member (7 The discharge valves (71) and (71) of (7) are opened, and hot water flows into the mixing chamber (5c) from the compartments (5a) and (5b).

  Here, in the present embodiment, since the opening directions of the first and second compartment outlets (53a) and (53b) intersect in the mixing chamber (5c), the first compartment outlet (53a ) And the hot water supplied from the second compartment outlet (53b) into the mixing chamber (5c) collided with each other vigorously and mixed sufficiently. Then, it is supplied from the mixing chamber (5c) through the discharge port (55) and the filter opening (97) into the bathtub (T).

  For this reason, even when hot water having different temperatures is supplied to the two flow paths (A) and (B), hot water having a temperature difference is sufficiently mixed in the mixing chamber (5c). By this, it is supplied and stored in the bathtub (T) in a state without temperature unevenness. Therefore, the temperature distribution of hot water stored in the bathtub (T) can be prevented from being biased, and a comfortable bathing environment free from temperature unevenness can be automatically obtained from the beginning of hot water.

  On the other hand, when performing a reheating process such as reheating the hot water in the bathtub (T), it is connected to the forward pipe of the outdoor water heater among the two flow paths (A) of the hot water outlet device (P). The flow path on the other side functions as a discharge flow path, and the flow path on the side connected to the return pipe functions as a suction flow path, so-called forced circulation is performed. For example, when the pipes are connected so that the first flow path (A) is a discharge flow path and the second flow path (B) is a suction flow path, the hot water supplied from the water heater is the first flow path ( A) flows into the first compartment (5a), opens the discharge valve (71) at the outlet of the first compartment (53a), flows into the mixing chamber (5c), and enters the discharge port (55) and It is supplied into the bathtub (T) through the filter opening (97).

  Further, in the suction channel, the second compartment (5b) becomes negative pressure due to the negative pressure of the return pipe of the outdoor water heater and the second flow channel (B). For this reason, the suction valve (72) of the second suction port (6b) in the flow path forming member (3) is opened by the water pressure in the bathtub (T), and the hot water in the bathtub (T) is filtered by the filter member (9). ) Through the second suction port (6b) and into the second compartment (5b), and then returned to the outdoor water heater through the second channel (B).

  Here, in the present embodiment, along the opening direction of the first and second compartment outlets (53a) (53b) to the first and second discharge port portions (55a) (55b) of the discharge port (55). Since the rectifying fins (59a) and (59b) are formed so as to rectify, the hot water flowing out from the discharge chamber side partition chamber outlet, that is, the first partition chamber outlet (53a) is rectified by the rectification fin (59a). Due to the action, the first discharge section (55a) discharges into the bathtub while maintaining the momentum along the outflow direction (Ea) of the first compartment outlet (53a). In this way, hot water is vigorously discharged into the bathtub and discharged along the inner surface of the bathtub, so that the hot water in the bathtub is sufficiently agitated and temperature unevenness can be prevented more reliably in the hot water. Can be performed without problems.

  In addition, 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 reverse manner, the flow paths (A) In (B), hot water is circulated in the opposite direction to that described above and forcedly circulated.

  Also in this case, the warm water flowing out from the second compartment outlet (53b) on the discharge flow path side is along the outflow direction (Eb) of the second compartment outlet (53b) by the rectifying action of the rectifying fin (59b). In the same manner as described above, the hot water in the bathtub can be sufficiently agitated since the second discharge part (55b) discharges it vigorously while maintaining the momentum.

  In this embodiment, a mixing chamber (5c) is formed in the apparatus main body (10), and hot water flowing out from the two compartments (5a) and (5b) is once introduced into the mixing chamber (5c). Since the water is discharged into the bathtub through the discharge port (55), for example, compared with the case where hot water is separately discharged into the tank from two compartments, the flow velocity and directionality at the time of hot water discharge It becomes easy to control etc., and warm water can be discharged efficiently and smoothly.

  Moreover, in this embodiment, since the valve member (7a) (7b) which has the discharge valve (71) and the suction valve (72) integrally is used, the number of parts can be reduced and the structure is simplified. And cost reduction can be achieved.

  Furthermore, the four valves of the first and second discharge valves (71) and the first and second suction valves (72) can be assembled simply by assembling the valve members (7a) and (7b) to the apparatus main body (10). Thus, the number of assembling steps can be reduced, the assembling work can be easily performed, and the cost can be further reduced.

  In addition, a valve support shaft (73) is formed at the connecting portion between the discharge valve (71) and the suction valve (72) in the valve members (7a) and (7b), and the shaft (73) is connected to the apparatus main body (10). Since it is assembled, the valve members (7a) and (7b) can be assembled in a stable state, the discharge valve (71) and the suction valve (72) can have high operational reliability, and the quality is improved. be able to.

  Moreover, in this embodiment, since the hot water is sucked into the bathtub from the front surface of the apparatus body (10) and the hot water in the bathtub is discharged from the peripheral side surface, a side discharge / front suction system is adopted. For example, at the time of hot water storage, hot water can be smoothly supplied along the inner surface of the bathtub, generation of sound due to scattering of the discharged hot water can be prevented, and hot water can be gently applied. Furthermore, when reheating, the hot water that is discharged spreads along the inner surface of the bathtub all over the inner peripheral surface, and the hot water in the center of the bathtub is sucked into the apparatus, so that the hot water is greatly stabilized in the bathtub. It is possible to effectively prevent a problem (short cycle) that circulates, for example, the discharged hot water is sucked into the apparatus without being circulated, and the reheating process can be performed efficiently and smoothly.

  Furthermore, in this embodiment, since the suction inlets (6a) (6b) of the compartment member (50) are formed by a large number of small holes, the hot water in the bathtub is drawn from the suction openings (6a) (6b). When sucking in, the suction force is dispersed to the periphery, so that dust such as hair floating in the bathtub can be prevented from being sucked into the suction ports (6a) and (6b), and the hair and the like can be separated from the compartment member (50). Can be prevented from being sucked into the vicinity of the suction port or into the apparatus.
