Abstract

PURPOSE:To eliminate the need of priming water and enable the start of a while pool by connecting the lower portion of water in a bath to the air phase part of the upper part of a feed water tank via a lifting pipe, connecting the delivery outlet of a pump to the lower portion of water in the bath via a delivery pipe, and providing the air outlet of an air discharge pipe on a feed water pipe. CONSTITUTION:A feed water tank 2 is supplied with water up to a water level A and a bath 4 contains the required amount of water. When a pump 3 is operated in the aforesaid state, water in the feed water tank 2 gushes onto water in the bath 4 by the predetermined amount due to the operation of the pump 3, via the route of a suction pipe 7, the pump 3, a delivery pipe 6 and the jet nozzle bath 4. Air stagnat ing in a lift pipe 5 enters the feed water tank 2 and air pressure at the air phase part G of the tank 2 drops. Consequently, the water level A temporarily drops to a level A1, and water flows from the lift pipe 5 to the tank 2. When the pump 5 is stopped, the water level returns to A due to an inflow from the lift pipe 5, because the air phase part G of the feed water tank 2 is in a negative pressure condition. As a result, the air pressure of the said part G returns to an original state. Also, water retained in the pump 3 can be properly maintained by locating the pump 3 below the water level A, and the smooth start of a while pool is guaranteed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention provides the following features:
By spraying warm water into the bathtub and stimulating the skin,
This invention relates to an improvement of a so-called whirlpool bathroom unit designed to promote blood circulation.

(Prior Art) Generally, in order to use a whirlpool in a bathroom unit, hot water circulation equipment such as a pump P is installed as shown in Fig. This has the advantage of making the construction work easier.

However, since this requires a large installation space, the lower part of the bathtub a is often used as the installation location, as shown by the solid line in the figure.

However, since the above-mentioned equipment sometimes causes water leaks, it is necessary to inspect and repair it fairly frequently, but since it is located in a closed area below the bathtub, it is necessary to check and repair it as soon as possible. It becomes difficult to detect, and the workability of inspection and repair itself is also poor.

Therefore, especially in the case of the above-mentioned conventional example, it is impossible to install a whirlpool bathtub on the upper floors of the second floor or higher, considering the possibility of damage caused by water leakage.

(Problems to be Solved by the Invention) As a result of studies in view of the above-mentioned conventional problems, the present invention has been developed by installing equipment such as a pump, which is particularly prone to problems such as water leakage, and a water tank from the ceiling panel of a bathroom unit. The pump is installed directly above the water supply tank and the bathtub, and the pump is connected to the water tank and the bathtub using appropriate piping. , it can be operated with a general-purpose pump without using a special pump with high suction pressure, and claim (1)
In addition, for the air discharge pipe installed at the appropriate location of the water tank, the intake port and the exhaust port are installed in the gas phase part of the water tank and the water supply pipe connecting the water tank and the pump, respectively. , the air in the water tank can be discharged to the outside, which means that once the water tank has been filled with water, there is no need to replenish water or prime water during operation, and it can be used instantly at any time and any number of times. Trying to get the whirlpool started.

Further, in claim (2), the reliability of operation as a whirlpool is further improved by setting the pump at a position lower than the water level of the water supply tank.

(Means for solving the problem) In claim (1) of the present application, in order to achieve the above object,
A water supply tank with a sealable water supply port and a pump are installed directly above the ceiling board of the bathroom unit body, and the water level below the water level of the bathtub provided in the bathroom unit body and the gas phase above the water supply tank are disposed. a water suction pipe which connects the water supply tank and the pump suction port by a discharge pipe, and connects the pump's discharge port and a jet nozzle opened below the water surface of the bathtub by a discharge pipe; attempts to provide a bathroom unit with a whirlpool, characterized in that an air outlet of an air discharge pipe with an air inlet opening is provided in the gas phase portion of the water supply tank.

Claim (2) above provides that the pump is disposed at a lower level than the water supply pump.

(Function) When the pump is operated with water supplied to the water supply tank to a specified water level and water also supplied to the bathtub, the water in the water supply tank is sucked out by the pump, and the water is pumped through the discharge pipe to the bathtub. As the water is ejected into the water inside the water supply tank, the water level in the water supply tank is lowered, and the air in the water pumping pipe enters the water supply tank to expand the gas phase.

At this time, the intake port of the air discharge pipe is located in the gas phase part,
Since the discharge port of the air exhaust pipe is installed in the water intake pipe, the air in the gas phase is discharged into the water in the bathtub through the air discharge pipe along with the flow of water due to the operation of the pump. .

As a result, the water level in the water supply tank, which has fallen as described above, rises and becomes stable near the intake port of the air discharge pipe.When the pump is then stopped, the gas phase in the water tank rises. Since there is still a negative pressure, the wood supplied to the bathtub is sucked up through the water pump and enters the water tank, causing the water level in the water tank to rise further and return to the initial water level. However, since the pump is on standby for the next pump start, there is no need to replenish water to the water tank.

(Embodiments) The present invention will be described in detail with reference to illustrated embodiments.
As clearly shown in FIGS. 1 and 2, a water tank 2 and a pump 3 are installed in the bathroom unit body l at appropriate locations on or directly above the ceiling panel la.
In the figure, 3a represents a pump motor, and 4 represents a bathtub provided within the bathroom unit main body l.

In the bathtub 4, the lower part of the water level, preferably the lower part of the bathtub 4, and the gas phase part G, which is the upper part of the water tank 2, are connected by a water pump 5 in the bedding. Therefore, when water is supplied to the bathtub 4, the water enters the pumping pipe 5 to the same level as the water level of the bathtub 4, and the water remains above it in a blocked state.

The water supply tank 2 has a water supply port 2b protruding from its upper wall 2a, and after supplying water into the water tank 2 from here, the water supply port 2b can be closed airtight with a closing lid 2c. In the illustrated example, the water pump 5 is connected to the peripheral wall of the water supply port 2b.

Further, the discharge port 3b of the pump 3 and the discharge nozzle 6a which is located in the bathtub 4 and is opened below the water level, preferably above the water inlet 5a of the pumping pipe 5, are connected by the discharge pipe 6. ing.

Next, in the present invention, the water supply tank 2 and the suction port 3C of the pump 3 are connected by a water suction pipe 7, and in the illustrated example, the water suction pipe 7 is installed horizontally through the water supply tank 2, and this water supply The lower inlet a of the pipe 7 is close to the bottom surface 2d of the water tank 2 and opens downward.

Furthermore, in the present invention, an air discharge pipe 8 is provided, and in this case, the intake port 8a of the discharge pipe 8 is located in the upper wall 2a of the water tank 2, and is opened close to the inner surface thereof. In addition, the discharge port 8b may be provided directly in the water suction pipe 7, but in the illustrated example, the air discharge pipe 8 installed vertically inside the water tank 2 is inserted through the water suction pipe 7. At the same time, the discharge port 8b of the air discharge pipe 8 is opened toward the pump 3 side, directly at the inlet lower a of the water intake v7.

Therefore, if water is supplied to the water tank 2 up to the water level A as shown in Fig. 2, and the required amount of hot water is present in the bathtub 4, the pump 3 is operated by the pump motor 3a. The water in the water supply tank 2 is pumped into the bathtub 4 by a predetermined amount by the pump 3 through the following route: lower a - suction pipe 7 - suction port 3cm pump 3 - discharge port 3b - discharge pipe 6 - jet nozzle 8a - bathtub 4. Since the air is ejected into the hot water, the air present in the water pump 5 enters the water tank 2, and as time ts elapses as shown in FIG. 3, the air pressure in the gas phase G of the water tank 2 becomes: As the pressure drops from P, which is 1 atm, to Pl, the water level A temporarily becomes A! decreases to

As a result, the discharge port 8a of the air discharge pipe 8 is located in the gas phase part G, so that from ts onwards, the discharge port 8a of the air discharge pipe 8 is located in the gas phase part G.
Since the air inside is released into the bathtub 4 together with the water sucked out by the pump 3, the gas phase G is about to be depressurized, causing hot water to flow from the water pump 5 into the water supply tank 2. As a result, the water level in the water supply tank 2 rises to the water level A2 near the intake port 8a of the near discharge pipe 8, as shown in Fig. 3, and a stable hot water circulation state as a whirlpool is established. It will continue to operate.

Next, if the operation of the pump 3 is stopped at the time t2 in FIG.
At this time, of course, the air pressure in the gas phase portion G also becomes the state P.

In addition, the pump 3 is connected to the water tank 2 as shown in the figure.
By arranging the pump at a lower level than the water level A in the pump, it is possible to secure water reserved in the pump, thereby ensuring smooth startup of the whirlpool.

(Effects of the Invention) The present invention is configured as described above, and the air in the water pump is discharged into the bathtub together with the water being sucked out due to the presence of the air discharge pipe, so that the air in the water supply tank is By supplying water, the water level in the tank can be kept constant at all times, which eliminates the problem of having to replenish water every time you drive.

Incidentally, when an air discharge pipe as in the present invention is not provided, when the water in the water tank is discharged into the bathtub by operation of the pump, the air in the water pump pipe is introduced into the water tank, and the air is removed. However, even if the pump is stopped, the lowered water level will be maintained as it is, and therefore, such use as a whirlpool may be repeated several times. As the water level in the water supply tank gradually decreases, it becomes necessary to supply water to the water tank from the water supply port in a timely manner.

Therefore, in the present invention, such problems are solved, and when the space directly above the bathroom unit is effectively used, there is no need to replenish water to a water tank located at a high place, which has a great effect.
As for the pump, the negative pressure in the gas phase of the water supply tank can be effectively utilized, so there is no need to use a special pump.
Since it is only necessary to install a small and lightweight device, the workability becomes good even if it is installed at a high place.

In addition, if attention is paid to the relationship between the water level of the water supply tank and the height of the pump installation as claimed in claim (2), the start-up of the whirlpool will be smooth and problems such as supplying priming water during use will be completely resolved. can.
