Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a bubble bath for ejecting a bubbly flow toward a bather.

(Prior art and its problems) Conventionally, this kind of bubble bath is formed by connecting a suction port provided in a tank part and a bubble jetting part with a circulation path having a circulation pump, and a circulation flow sucked from the suction port is formed. It was designed to send a bubble flow to the bubble flow jetting part.

By the way, in general, floating matters such as dirt and hair float on the surface of the hot water in the bathtub, which often gives the bather discomfort.

Therefore, it may be considered to provide an inlet in the bubble bath near the water surface above the bath and collect the suspended matter on the surface of the hot water through the inlet.

However, according to the above-described structure, when the water level is lowered due to the use of hot water in the tank or the like, air may be sucked from the suction port and the circulation pump may be damaged. In order to prevent such a problem, in the conventional bubble bath, the suction port is provided near the bottom of the tank portion, and thus it is impossible to collect the suspended matter on the surface of the hot water from the suction port.

(Problems to be Solved by the Invention) The present invention has been made in view of such conventional circumstances, and the purpose thereof is to make the suction port near the water surface above the tank portion, that is, the hot water in the tank. It is located near the surface so that the suction port is opened and closed with the rise and fall of the water level, and the hot water in the tank can be sent to the circulation pump even when the suction port is closed.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the bubble bath of the present invention has suction ports provided near the upper water surface and near the lower bottom wall of the tank, respectively, and is installed above the circulation passage upstream of the circulation pump. Two branch passages that connect to the suction port and the lower suction port are provided, a strainer is provided inside the upper suction port, and a detection means for detecting the water level in the tank is provided. It is characterized in that an opening / closing means for opening / closing the branch path is provided based on a signal from the detecting means, and the opening / closing means is closed when the detecting means detects that the water level in the tank is lower than the upper intake port.

(Operation) According to the above means, in the state where the water level in the tank is higher than the upper suction port, the branch passage on the upper suction port side is opened by the operation of the opening / closing means, and the upper suction port serves as the bubble jetting part. The hot water near the surface in the tank is sent to the bubble jetting part by the operation of the circulation pump to jet the bubble jet. At the same time, the suspended matter on the surface of the hot water is sucked by the upper suction port and collected by the strainer.

When the detection means detects that the water level in the tank has dropped below the upper suction port, the opening / closing means operates to close the branch passage on the side of the upper suction port and stop the suction from the upper suction port.

Further, the lower suction port always communicates with the bubble flow ejection part regardless of the water level in the tank, and sucks the hot water near the bottom wall in the tank by the operation of the circulation pump and sends it to the bubble flow ejection part.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. In the drawing, the tank portion (1) is shown in cross section, and the circulation path (6) communicating with the tank portion (1) is simplified.

The cover (12) has a slit (14) communicating with the inlet (10).
And an opening wall (15) screwed onto the inner circumference of the screw ring (13).
Secure with the screws (16).

The lower suction port (3) has an inlet (10 ') below the tank wall (1a) near the bottom wall (1b) of the tank (1), and the upper suction port is located at this inlet (10'). Similar to (2), the strainer (11), the cover (12), the screw ring (13), etc. are provided (see FIG. 2).

The bubbly flow jetting portion (4) is not described in detail, but the circulation pump (5)
Is equipped with a nozzle that squeezes the flow path of the circulation flow that is supplied by the function of, and an air adjustment device that mixes air into the circulation flow by the suction force of the jet flow that is squeezed by this nozzle is provided upstream of the nozzle. It has a well-known structure that I contacted.

The circulation path (6) is provided with a circulation pump (5) with a filtration function, whose operation is controlled by an operation section (17) provided on the upper edge surface (1c) of the tank section (1) in the middle thereof. There is.

And the circulation path (6a) on the upstream side of this circulation pump (5)
The above-mentioned two branch paths (7) and (8) are branched, and the base end portions thereof are respectively the inlet portions (10) and (10) of the respective suction ports (2) and (3).
It is connected to (10 '). Further, the tip of the circulation passage (18) on the downstream side of the circulation pump (5) is connected to the nozzle of the bubble jetting portion (4).

The opening / closing means (9) is composed of an electromagnetic opening / closing valve for opening / closing the flow path of the branch passage (7) on the side of the upper intake port (2), and is provided on the upper edge surface (1c) of the tank part (1). It is electrically linked to the control section (19) to control its operation.

The control section (19) is electrically linked to the detection means (20) provided in the tank section (1), and the opening / closing means (9) is in a state where a detection signal is sent from the detection means (20).

The detection means (20) has a well-known structure composed of a water level sensor, and is provided directly above the upper suction port (2) above the tank wall (1a). A detection signal is sent to the control section (19) when the water level above the mouth (2) is reached.

The operation of the bubble bath in this embodiment will be described below.

When hot water is poured into the tank (1) and the water level reaches the set water level, a detection signal is sent from the detection means (20) to the control section (19), and the opening / closing means (9) is activated to operate the upper suction port ( The flow path of the branch path (7) on the 2) side is opened. In this state, when the operation part (17) is operated to operate the circulation pump (5), hot water is sucked from the upper and lower suction ports (2) and (3) and sent to the bubble flow jetting part (4), A bubble flow is jetted from the bubble jet portion (4). At that time, the suspended matter on the surface of the hot water is sucked by the upper suction port (2), the suspended matter is recovered by the strainer (11), and the circulation flow is filtered by the filtration function of the circulation pump (5).

When the hot water in the tank (1) falls below the set water level, no detection signal is sent from the detection means (20), and the opening / closing means (9) is activated by a command from the control section (19) to activate the upper suction port ( The flow path of the branch path (7) on the 2) side is closed. In this state, the circulation path (6)
The hot water sucked from the lower suction port (3) flows into the chamber and is sent to the bubble flow jetting section (4) to jet the bubble stream.

In addition, the strainer (11) inside the branch passage (7) can be removed by removing the cover (12) and the screw ring (13) from the upper and lower inlets (10) and (10 ') in a state where the bubbly flow is not ejected. Remove it and clean or replace it.

As a result, the hot water in the tank can be kept cleaner. The circulation pump (5) is not limited to the one having a filtration function, and a filter (not shown) may be provided in the middle of the circulation path (6).

(Effect of the Invention) Since the present invention is configured as described above, the hot water sucked from the suction port by the operation of the circulation pump can be ejected as a bubbly flow into the tank, and the suspended matter on the surface of the hot water can be collected. When the water level in the tank is lower than the upper intake port, the branch passage on the side of the upper intake opening can be closed to prevent the possibility of failure of the circulation pump due to air mixed in the branch passage.

Therefore, in addition to the massage effect by the jet of bubbly flow,
We were able to provide a new bubble bath that collects floating substances such as dirt and hair floating on the surface of the hot water to give a more pleasant bathing feeling.
