  In the hot water outlet device (P) having the above-described configuration, the two pipes of the forward pipe and the return pipe from the outdoor water heater are respectively connected to the external fitting connection portions (1a) and (1b) of the external fixture (1). Thus, a bathtub system is formed.

  As shown in FIGS. 1 and 11, in this bathtub system, when hot water is supplied into the bathtub (T) to store hot water, the first and second outsides are connected from the outdoor water heater through the return pipe and the return pipe. Hot water is supplied to both of the pipe connections (1a) and (1b). As a result, the hot water passes through the first and second flow paths (A) and (B), and passes through the first and second communication holes (51a) and (51b), so that the first and second compartments (5a) ( 5b) is introduced into the upstream areas (58a) and (58b) and further led to the first and second compartment downstream areas (59a) and (59b) through the first and second filters (7a) and (7b). . Then, the hot water passes through the first and second filter openings (71a) (71b), the first and second hot water port channels (54a) (54b), and passes through the first and second hot water ports (6a) ( 6b) is discharged into the bathtub.

  On the other hand, when performing a reheating process that reheats the hot water in the bathtub (T), the forward pipe of the outdoor water heater among the two flow paths (A) and (B) of the hot water outlet device (P). 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).

  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.

  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.

  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.

  In the present 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 reverse 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.

  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.

  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.

  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.

  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.

  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.

  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. .

  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.

  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.

  In addition, in this invention, the partition structure by the filter of a division chamber is not restricted only to the thing of the said embodiment.

  For example, as shown in FIG. 12, without providing the first and second hot water outlet channels (54a) (54b) in the compartment member (50), the front side of the filters (7a) (7b) and the first and second The filter (7a) in the first and second compartments (5a) and (5b) is communicated between the two flow paths (A) and (B) by the first and second communication paths (154a) and (154b). The upstream areas (58a) and (58b) may be formed in front of (7b), and the downstream areas (59a) and (59b) may be formed in the rear.

  Further, as shown in FIG. 13, the cylindrical filter member (7) is arranged in a state in which the axial center coincides with the interior of the compartment member (50), and the cylindrical filter member (7) allows the first and The second compartment (5a) (5b) may be divided into an inside and an outside, and the inside may be configured as an upstream region (58a) (58b) and the outside as a downstream region (59a) (59b).

  By the way, in the said embodiment etc., although the case where it applied to the hot-water-mouth apparatus for bathtubs of a system with which a valve is not provided in a partition chamber member (50) was demonstrated, it is not restricted only to it, and this invention is the inside of a partition chamber member. The present invention can also be applied to a hot water outlet device for a bathtub in which a valve is provided. For example, in the present invention, first and second discharge ports that communicate with the first and second compartments and first and second suction ports that communicate with the first and second compartments are provided on the outer surface of the compartment member. In addition, first and second discharge allowance valves that allow hot water to flow only in the discharge direction are provided at positions corresponding to the first and second discharge ports, and the suction direction is at positions corresponding to the first and second suction ports. It can also be applied to a hot water port apparatus for a bathtub provided with first and second suction permissible valves for circulating hot water only. Further, among the hot water outlet devices for bathtubs with a valve, the first discharge permissible valve and the first suction permissible valve are integrally formed, and the second discharge permissible valve and the second suction permissible valve are integrally formed. It can be applied to a hot water outlet apparatus for bathtubs.

  In the present invention, the filter member is not necessarily provided inside the apparatus, and may be provided on the outer peripheral surface of the apparatus such as a decorative cover.
