Further, in the bath device of the present invention, when the bath kettle is of a jacket type, the time required for the water filling can be shortened by specifying the outlet portion of the bath filling circuit from the water heater in the bath kettle. It is something to do.

[Prior art and its problem] In a bath apparatus having a built-in water heater and bath kettle, the water filling circuit from the water heater is connected to a jacket-type heat exchanger bath Hot water is supplied to the bathtub via the bath kettle, and is actually
Proposed as an issue.

In this prior art, since the outlet part of the water filling circuit is provided on the wall surface facing the open end of the endothermic tube of the bath kettle communicated so as to circulate and heat the bathtub, The passage resistance of the hot water supplied to the bath via the bath is eased, and the time required for filling the water can be shortened compared to the past.

However, it is not possible to sufficiently shorten the time required to fill the water by just making the outlet of the water filling circuit face the end of the endothermic tube of the bath kettle. This is because the flow generated in the bath kettle by the hot water discharged from the water filling circuit into the bath kettle may cause resistance in the path inside the bath kettle from the outlet of the water filling circuit to the bathtub.

The present invention is such a "jacket-type bath pot (1)"
The bathtub (B) and the bathtub (B) are connected by a pair of connecting water pipes (11, 12), and the water filling circuit (30) of the water heater (3) built in the casing (K) together with the bathtub (1) is connected. A rectangular tubular jacket (J) in which the outlet (31) is connected to the bath kettle (1) and the bath kettle (1) is opened vertically.
It is an object of the present invention to shorten the time required for filling water in a bath apparatus with a water heater, which has a structure in which a heat absorption pipe (13) is bridged between the opposing inner walls.

[Technical Means] The technical means of the present invention taken to solve the above-mentioned problem is that "a flat chamber of the jacket (J) and connecting water pipes (11) (12) are vertically arranged in series. The outlet wall (31) of the water filling circuit (30) is provided on the constituent wall of the first empty chamber (14), and the opening direction of this outlet (31) is parallel to the longitudinal wall surface of the first empty chamber (14). It was set to ".

[Operation] The technical means of the present invention operates as follows.

When the bathtub (B) is filled with water through the water filling circuit (30), the warm water from the water filling circuit (30) is heated by the jacket (J).
From the outlet (31) provided in the wall of the structure to the first empty chamber (14), and from the communication water pipes (11) (12) connected to the first empty chamber (14) and into the bathtub (B). leak. At this initial stage of filling the water, since the communication water pipe (11) is open in the bathtub, bubbles and the like generated in the jacket (J) at the time of this inflow are passed through this communication water pipe (11). It is discharged into the bath (B).

In addition, at the time of this hot water filling, the opening direction of the outlet (31) coincides with the longitudinal direction of the wall surface of the first vacant chamber (14), so that the hot water ejected from the outlet (31) has no resistance. It flows into the first vacant chamber (14). In addition, since the air in the jacket (J) is in the shape of a rectangular tube, there is a tendency that an orbital flow (see the arrow in FIG. 1) occurs in the jacket (J) as a whole, and the resistance is reduced by one tank. Become. And this first
The hot water flowing into the empty room (14) is supplied to the bathtub (B) in the above process.

When hot water is discharged into the first empty chamber (14) by the subsequent filling of water, the air remaining in the jacket (J) is sent to the bathtub (B) side in accordance with this discharge.

[Effects] The present invention having the above-described configuration has the following unique effects.

During hot water filling, when hot water is discharged from the outlet (31) into the jacket (J), the discharge resistance of the hot water is hardly generated. Swirling flow and hot water filling circuit (3
Since the discharge direction from 0) is the same, the outflow resistance is further reduced, and the time required for filling with water can be shortened.

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

In this embodiment, as a whole, it is constructed as shown in FIG. 3, and the arrangement of the bath kettle (1) and the relationship with the water heater (3), and further, the bathtub (B) and the bath kettle (1). The communication connection relationship of is the same as the conventional one, and the water filling circuit (30) from the water heater (3) is connected to the jacket (J) of the bath kettle (1) via a hopper device as a vacuum breaking means. It is connected. Further, in order to improve the efficiency of circulation heating in the bathtub (B) by the bath kettle (1) and to enhance the stirring effect in the bathtub (B), a forced circulation circuit (2) having a pump (P) inserted therein. Is installed side by side, and as shown in the figure,
The upper connecting water pipe (11) faces the outlet pipe (21) of the forced circulation circuit (2), and the lower connecting water pipe (12) faces the inlet pipe (22) of the forced circulation circuit (2). There is.

The bath kettle (1) used in this embodiment has a structure in which the endothermic tube (13) is heated by the gas burner (10) disposed below, and as shown in FIG. 1, the wall surface of the bathtub (B). Both ends of the first vacant chamber (14) parallel to and the second vacant chamber (15) facing the first vacant chamber are communicated with the lateral vacant chambers (16) and (16), and the four vacant chambers as a whole are rectangular tubes. The heat absorbing tubes (13) are connected to each other and surround the heat absorbing tube (13).

The endothermic tube (13) is installed and communicated between the side empty chambers (16) and (16), and as shown in FIG.
It is mounted in an inclined state between the lower part of 6) and the upper part of the other lateral chamber (16), and a large number of fins (F) (F) are arranged on the outer circumference. The connecting water pipes (11) and (12) are arranged on one side of the outer surface of the first vacant chamber (14) so as to have a certain interval in the vertical direction, as shown in FIG.
The outlet pipe (21) of the forced circulation circuit (2) is arranged facing the 1), and the inlet pipe (22) of the forced circulation circuit (2) is arranged facing the connecting water pipe (12) below. ing. A pump (P) for forced circulation is inserted in the forced circulation circuit (2), and this pump (P) is set to an operating state by a signal for this during circulation heating operation.

In the above embodiment, when hot water is filled from the water filling circuit (30) to the bathtub (B) via the bath kettle (1), hot water discharged from the outlet (31) is as shown by an arrow in FIG. Flow in the longitudinal direction of the first empty chamber (14), and after circulating the air in the annular jacket (J) consisting of each empty chamber, the air is discharged from the connecting water pipe (12) to the bath (B), The action described above can be obtained.

The resistance of the hot water discharged from the outlet (31) increases in the state where the filling operation progresses, but in this state, the effect that hot water discharged from the outlet (31) circulates along the arrow in FIG. That is, the above-described resistance relaxation effect becomes particularly effective.

In addition, during the water filling, the hopper (H) of the water filling circuit (30)
Air is mixed in at the outlet (31) of the water filling circuit.
When hot water is discharged from the jacket, air is stored in the jacket (J), and this stored air is sent to the communication water pipe (11) side along the flow of the discharged hot water in the jacket (J),
The water is discharged from the connection water pipe (11) into the bathtub (B). Therefore, air is unlikely to be stored in the jacket (J), and the operation of the pump (P) is not adversely affected.

Therefore, when the inside of the bathtub (B) is to be reheated after the completion of filling with water, the gas burner (1
When (0) is set to the combustion state and the pump (P) is set to the operating state, the inside of the bathtub (B) is forcibly circulated, and suction is made in the outlet pipe (21) and the inlet pipe (22) bent in an L shape. The hot water stored in the jacket (J) is forcibly circulated by the discharging action, and the heat exchange efficiency of the bath kettle (1) is improved as compared with the natural circulation type.

In the above embodiment, the connecting water pipe (11) is located right above the connecting water pipe (12), but as shown in FIG.
The connecting water pipe (11) may be arranged so as to be shifted from the position right above to the right in the figure. In the case of FIG. 4,
When hot water is discharged from the outlet (31), the air mixed in the discharged hot water is directly discharged through the communication water pipe (11) at this portion, and it becomes more difficult to store the air.

Further, as shown in FIG. 1, when the cross-sectional area of the first empty chamber (14) is made larger than that of the second empty chamber (15) and the lateral empty chamber (16), the above effect is further improved.
