Abstract

PURPOSE:To improve usability and to add a massage effect by ejecting jet stream and air, which is ejected from an ejector, from plural through holes on a partition wall. CONSTITUTION:When a circulating pump 12 is operated in a state that hot water is put in a bathtub 11, an ejector 14 is operated and the air is sucked from an air pipe 16. Then, fluid mixing the air is ejected into an ejector room 18. Since designing the area of a duct to be gradually small for the ejector room 18 according to a distance from the ejector 14, there is an effect to uniform the distribution of positive pressure in the ejector room. Then, the uniform quantity of the jet stream and air are ejected from plural through holes 19 in a mixed state. When an air adjusting valve 15 is closed, the bathtub can be used only with the jet stream.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a bubble bathtub having a bubble massage function.

Conventional technology This is the third bubble bathtub with a bubble massage function.
There are some as shown in Fig. 4. In Figure 3, l
is a bathtub, and a circulation circuit 3 is installed in this bathtub l via a circulation bomb 2.

4 is an ejector arranged between the circulation pump 2 and the bathtub 1. The ejector 4 is provided with an air pipe 6 provided with an air conditioning hub 5. In such a bubble bathtub, when the circulation pump 2 is operated during use, a jet flow flows into the bathtub 1. At this time, when the air control valve 5 is opened, atmospheric air is sucked from the ejector 4, and a jet of bubbles acts on the body. In addition to this type, there is a bubble bathtub of the type shown in FIG. In FIG. 4, reference numeral 7 denotes a bathtub, and a cloak 8 having an air hole is provided at the bottom of the bathtub 7, and an air pump 9 is connected to the bathtub B via a pipe 1O. To use this bubble bathtub, when taking a bath, the air pump 9 is activated, and air is discharged into the bathtub through the pipe 10 from the air holes of the manoeuvres 1 and 8.

Problems to be Solved by the Invention However, in the conventional example, the spread of the jet and the bubbles is limited to the vicinity of the position where the ejector 4 is arranged, so the body must be moved in order to apply the bubbles to the body, making it difficult to use. was bad.

In addition, the type that uses an air pump only ejects air, so it does not have a massaging function using water flow, and when evaluated from the actual usage experience, the massaging effect was insufficient.

Therefore, an object of the present invention is to provide a massage effect and improve usability by ejecting jets of water and air onto the body from at least one entire surface of the bathtub.

Means for Solving the Problems In order to solve the above problems, the present invention provides a circulation circuit for circulating hot water in a bathtub, a circulation pump provided in the circulation circuit, and a system between the circulation pump discharge side and the bathtub. at least one ejector arranged therein and having an air suction port; a partition wall that partitions the interior of the bathtub into an intake chamber to which the ejector is arranged and a bathing room for bathing; and a plurality of ejectors extending through the partition wall. It is constructed with a through hole.

Function: The present invention has the configuration described in -I-2, and by ejecting the jet and air from the ejector from the plurality of through holes in the partition wall, the usability is improved and a massage effect is added.

Example An embodiment of the present invention will be described below with reference to FIG.

11 is a bathtub, and this bathtub 11 is provided with a circulation circuit 13 via a circulation pump l2. 14 is an ejector arranged between the circulation pump 12 and the bathtub 11. The ejector 14 is provided with an air pipe 16 provided with an air conditioning pulp 15. 17 is the bathing room, 1
8 is an ejector chamber, and the ejector chamber 11 and the ejector chamber 18 are separated by a partition wall 2o having a plurality of through holes 19. Further, the ejector chamber 18 has an ejector 14
The flow path area is designed to decrease as the distance from the flow path increases.

Next, another embodiment of the present invention according to FIG. 2 will be described. 21
is a dividing wall that divides the bathing bath 22 and the ejector chamber 23, and a rubber seal 25 is provided on the outer periphery of this dividing wall 21 as an airtight means for sealing the bathtub 24. Moreover, the goodwill partition wall 21 and the rubber seal {A25 are constructed in a negative body, and are configured to be detachable from the bathtub 24.

Next, the operation of the present invention will be explained with reference to FIG. When the circulation pump 12 is operated with hot water in the bathtub 11, the ejector 14 works to suck air from the air pipe 16, and the fluid mixed with air is ejected into the ejector chamber 18.

The ejector chamber 18 is designed to have a flow path area smaller as it moves away from the ejector 14, which has the effect of making the positive pressure distribution in the ejector chamber uniform, and a uniform amount of jet and air is released from the plurality of through holes 19. It is squirted out in a mixed state. Also, if the air adjustment valve 15 is closed,
It can be used only with a jet stream.

Next, the operation of another embodiment will be explained with reference to FIG.

In this embodiment, the partition wall 21 and the bathtub 24 are sealed with rubber seals t and l.
By making it possible to freely attach and detach via '25,
This has the effect that the bathtub 24 can be cleaned easily.

[Effects of the Invention] As shown in 2, there is a circulation circuit for circulating hot water in a bathtub, a circulation pump installed in the circulation circuit, and a circulation pump disposed between the discharge side of the circulation pump and the bathtub for air circulation. By providing at least one ejector having a suction port, a partition wall that partitions the bathtub into an ejector chamber to which the ejector is arranged and a bathing bath, and a plurality of through holes penetrating the partition wall, A jet stream containing air can flow out from a plurality of through holes over the entire bathing area, and the jet stream can be applied to the body without moving the body during use. It also has the effect of increasing the massage effect compared to when only air flows out.
