DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nozzle device having a single nozzle which also serves as a circulation port for washing a bath, blowing bubbles, and reheating.

[0002]

2. Description of the Related Art When an automatic washing apparatus or a bubble blower is installed in a bathtub, each nozzle is separately installed.

[0003]

Therefore, there are the following problems.

A. Since a large number of nozzles protrude into the bathtub, the design is not good and it is an obstacle when taking a bath.

B. Equipment is troublesome and expensive because the piping is separate.

C. Each control becomes complicated.

An object of the present invention is to provide a nozzle device which does not have the above-mentioned problems a to c.

[0008]

The configuration of the nozzle device according to the present invention is as follows.

A nozzle body having an air inlet and a washing water inlet formed therein, and an air flow path and a washing water flow path following the air inlet and the washing water inlet formed therein; and a driving source in and out of the nozzle body. The air flow path is freely closed and the air flow path is closed, while the cleaning water flow path is opened so that cleaning water can be jetted from a nozzle mounted on the front and the air flow path and the cleaning state are retracted. A nozzle device for a bathtub, comprising: a cylinder that opens both water channels and mixes air and hot water from a nozzle to spray foam; and a controller that instructs a driving source to advance and retreat the cylinder.

[0010]

[Action]

a. Automatic cleaning of bathtub When the controller is set to cleaning, the drive source is driven and the cylinder moves forward, closing the air inflow path and opening the cleaning water flow path. As a result, the washing water flows from the washing water inlet through the washing water flow path, through the cylinder, to the nozzle, and blows out into the bathtub. The washing water jetted into the bathtub is once collected by a washing unit (not shown), reaches the nozzle device again after heating, jets the jet from the nozzle into the bathtub, and cleans the bathtub with the jetting energy and chemical power. .

B. When the foam blow controller is set to foam blow, the drive source is driven to retract the cylinder, opening the air flow path and, at the same time, keeping the wash water flow path open. As a result, air is mixed into the circulating hot water, which foams out of the nozzles and blows out vigorously, forming foam. In addition, at the time of foam blowing, the supply of the cleaning agent and the heater on the cleaning unit side are stopped, and the hot water in the bathtub circulates as it is.

C. When the reheating controller is set to reheating, the heater is driven in the above-described cleaning state, and the heated water is jetted into the bathtub via the nozzle device, and the circulation is repeated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, reference numeral 1 denotes a bathtub, and 2 denotes a nozzle device. The nozzle device 2 is set on the back side of the wall of the bathtub 1 and has a washing water inlet 4, an air inlet 5, and an air inlet. Nozzle body 3 having passage 6 and washing water passage 7 formed therein
And a cylinder 9 incorporated in the main body 3 so as to be slidable back and forth by a drive source 8 as main components.

Reference numeral 10 denotes a driving screw formed at the rear of the cylinder 9. A driving bolt 11 of a driving source 8 is screwed into the driving screw 10, and the rotation of the driving bolt 11 causes the cylinder 9 to move forward or backward. Reference numeral 12 denotes a cylinder flow path provided in the cylinder 9, which is always in communication with the washing water flow path 7 via an inlet 13.

A nozzle 14 is mounted at the center of the front side mounting plate 2 'of the main body 3 so as to be capable of adjusting the jetting direction. The front end of the cylinder 9 is connected to the rear end 1 of the nozzle 14.
It is free to enter and exit 4 '.

Reference numeral 15 denotes a cylinder 9 for contacting the rear end 14 'of the nozzle 14 to close the rear end of the nozzle 14 or to be opened when the cylinder 9 retreats to communicate the nozzle 14 and the air flow path 6. An air valve is provided so as to be always pushed forward by a spring 16.

Next, the operation of the above nozzle device will be described.

A. Bathtub automatic cleaning (state of FIG. 1) When the cleaning mode switch of the controller (not shown) is turned ON, the drive source 8 is driven and the drive bolt 11 is rotated,
By the action of the driving screw 10 screwed with this, the cylinder 9
Moves forward, the tip of the cylinder 9 enters the rear end 14 ′ of the nozzle 14, and at the same time, the air valve 15 comes into close contact with the rear end 14 ′ and closes the air flow path 6 side. As a result, the washing water flows into the washing water inlet 4 of the main body 3 → the washing water channel 7 → the cylinder 9
The inside of the bathtub 1 is washed by flowing in the flow path 12 → the nozzle 14 → the inside of the bathtub 1.

B. When the foam blow mode switch of the controller is turned on, the drive source 8 is driven to rotate the drive bolt 11 in the opposite direction to the previous one, and the cylinder 9 is retracted by this action. Then, the tip of the cylinder 9 is moved away from the nozzle 14 and the air valve 15 is moved backward to separate it from the rear end 14 ′ of the nozzle 14, thereby opening the air passage 6 and the nozzle 14.

As a result, the air inlet 5 → the air passage 6
The air flows from the nozzle 14 to the bathtub 1 and mixes with the hot water flowing from the cylinder 9 side in the nozzle 14, and blows out into the bathtub 1 as bubbles.

C. Reheating (State of FIG. 1 or State of FIG. 2) When the reheating mode switch of the controller is turned ON,
The circulation pump and the heater are driven in the state of the above a or b, the hot water in the bathtub 1 is heated, and once enters into the flow path 12 in the cylinder 9 from the washing water inlet 3 of the main body 3, and from the nozzle 14 The water is spouted into the bathtub 1 and reheating is performed by this circulation.

[0022]

As described above, according to the present invention, a cylinder operated by a remote control is incorporated in the main body, and a washing process, a bubble blowing process, and a reheating process are freely set by this operation, and all are performed by one nozzle. Thus, the following effects are obtained.

A. Since there is only one nozzle, the design is good and it does not get in the way when bathing.

B. By installing the nozzle device according to the present invention, piping such as cleaning, foam blowing, and reheating need not be performed for separate nozzles, so that the construction is simple and the cost is low.

C. Control is easy because only the cylinder is operated.
