  During this hot water circulation, the hot water sucked into the outdoor water heater from the bathtub (T) passes through the second compartment downstream area (59b) from the second hot water port (6b) and further passes through the second filter (7b). Since it passes through, the filter (7b) removes foreign matters such as dust in the hot water and impurities. Accordingly, dust or the like does not enter the hot water outlet device (P) or the outdoor water heater, and problems due to the entry can be reliably prevented.

  In addition, in the additional cooking process, 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, Hot water flows through the flow paths (A) and (B) in the direction opposite to the above and is forcedly circulated.

  As described above, according to the hot water port apparatus (P) for bathtubs of the present embodiment, the first and second hot water ports (6a) and (6b) are used as discharge ports when hot water is stored, and either one is used for additional cooking. The hot water port is used as a suction port. 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. .

  In the present embodiment, the filter cleaning operation and the like can be performed without hindrance. 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. 10, without providing the first and second hot water outlet channels (54a) (54b) in the compartment member (50), the front side of the filter (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. 11, the cylindrical filter member (7) is arranged in a state in which the axial center coincides with the inside of the partition chamber 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).
