まった湯をドレン管から抜き出すことも考えられるが、
この場合、フィルタ内にエアーが入ってこないため密閉
状態にあるフィルタ内は負圧になり、内部の湯をうまく
抜き出すことができない。In such a bathtub apparatus, hot water is drained from the bathtub when it is not used for a long time. At this time, it is preferable to drain all the hot water in the circulation system. However, since the filter incorporated in the circulation system has a tank structure inside, it is difficult to extract hot water accumulated in the filter. If the hot water is left standing in the filter, problems such as propagation of various bacteria occur, which is not preferable in terms of hygiene. Therefore, it is conceivable to connect a drain pipe to the lower part of the filter and to draw out hot water accumulated in the filter from the drain pipe when not in use.
In this case, since air does not enter into the filter, the inside of the filter in a sealed state has a negative pressure, and the hot water in the inside cannot be properly extracted.

In a bathtub apparatus provided with a filter for removing dust mixed in hot water in a tank and a drain pipe attached to the filter, a communication pipe for opening the inside of the filter to the atmosphere is provided. It is characterized in that a check valve is provided to allow the flow of the fluid to the filter but to prevent the flow of the reverse fluid. The invention according to claim 2 is characterized in that the communication pipe is provided so as to communicate the upper part of the filter and the overflow discharge part provided on the upper part of the bathtub. In the invention described in claim 3, the check valve is arranged so as to face up and down and has a fluid passage having a valve seat at an upper end, a valve body interposed in the fluid passage, and a valve body. A spring that urges the valve so as to abut against the seat, wherein the spring is set to have such strength that the valve body separates from the valve seat by its own weight when hot water in the filter is extracted from the drain pipe. It is characterized by.

It is assembled to the joint 17 of the circulation system 10 so that 1a is at the upper end position. The spring 23 is provided with the check valve 20.
When the valve seat 21a is arranged upward as described above, the strength is set so that the valve body 22 can be held at a position facing the valve seat 21a with a slight gap as shown by a solid line in FIG. Have been. Therefore, when the pump 11 is turned on and a predetermined fluid pressure is applied to the circulating system 10 on the pump discharge side, the water pressure in the circulating system 10 is applied above the pressing force of the spring 23, and thus two points in FIG. As shown by the chain line, the valve body 22 comes into contact with the valve seat 21a, and the check valve 20 is "closed".
On the other hand, when the pump 11 is turned off and pressure is not applied to the circulation system 10, the valve body 22 descends by its own weight, and a gap is formed between the valve body 22 and the valve seat 21a. The check valve 20 is in an "open" state.

When the hot water stored in the tank 4 is subjected to processing such as sterilization, the pump 11 is operated. Then, the hot water in the tank 4 is supplied from the lower part of the tank to the pump 1
1, the hot water is discharged from the discharge port of the pump 11, and the discharged hot water is sequentially sent to the filter 12, the sterilizing device 13, and the heating device 14, and after each device performs a predetermined process, It is returned into the tank through the conduit 10c. That is, while the dust in the hot water is removed by the filter 12, the proliferation of bacteria in the hot water is suppressed by the sterilizing device 13, and the hot water is heated by the heating device 14 so that the temperature of the hot water in the tank 4 is kept constant. Kept in range.

Is turned on and a predetermined water pressure is applied to the circulation system 10 on the pump discharge side, so that the valve body 22 comes into contact with the valve seat 21a, and the check valve 20 is in the "closed" state after all. . Therefore, the hot water in the circulation system 10 does not flow out to the overflow discharge section 19 through the communication pipe 18.

しが行える。When bathing is completed and hot water in the bathtub is drawn out, at the same time, the valve 16a is manually opened to draw out hot water stored in the filter 12. Here, at the time when the processing by the sterilizing device 13 or the like is completed and the pump 11 is stopped, the predetermined pressure is not applied to the circulation system 10, so that the check valve 20 is already in the “open” state, Is connected to the atmosphere via a communication pipe 18. Therefore, when the hot water in the filter is extracted from the drain pipe 16, the inside of the filter 12 does not become negative pressure, and therefore, the hot water in the filter can be smoothly extracted.

減、並びに低コストかが図れる。As described above, according to the present invention, the following excellent effects can be obtained. According to the invention described in claim 1,
A check valve that allows the flow of fluid from the atmosphere side to the filter but prevents the reverse flow of fluid is provided in the communication pipe that opens the inside of the filter to the atmosphere, so that the hot water stored in the filter can be drained. When air is extracted from the filter, air enters the filter through the communication pipe, so that the inside of the filter is maintained at atmospheric pressure without negative pressure, and as a result, the hot water is smoothly extracted from the filter. According to the second aspect of the present invention, since the communication pipe is provided so as to communicate the upper part of the filter and the overflow discharge part provided at the upper end of the bathtub, for example, the check valve does not operate well and the communication pipe is not operated. Even if the hot water in the filter flows backward from the filter, the hot water flowing from the filter flows into the overflow discharge portion, and does not cause any trouble in the bathtub or the circulation system. According to the third aspect of the present invention, the check valve includes: a fluid passage having a valve seat;
Since the valve has a valve body interposed in the fluid passage and a spring that urges the valve body so as to abut on the valve seat, it has a simple structure. The structure can be in a state, and the number of parts can be reduced and cost can be reduced.
