Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to a device that sucks hot water from a bathtub, sprays the hot water with bubbles into the bathtub, and massages the human body with ultrasonic waves generated when the bubbles burst.

[Conventional technology and its problems]

A device has been developed that vigorously sprays hot water containing bubbles into a bathtub. This device uses a circulation pump to draw in hot water from a bathtub, sucks air into the hot water, and injects bubble-containing hot water. That is, air is sucked into the hot water using negative pressure caused by a high-speed flow injected from a circulation pump. By the way, this type of foaming device is known to generate ultrasonic waves to massage the body surface when the countless bubbles sprayed into hot water are destroyed or when the bubbles combine with each other. . BACKGROUND ART A foaming device for a bath that sprays air-containing hot water into a bathtub can efficiently generate ultrasonic waves that effectively massage the human body. However, with this type of foaming device for baths, ultrasonic waves cannot be uniformly propagated throughout the hot water in the bathtub, and strong ultrasonic waves are generated locally in the hot water injection area. Therefore, in order to effectively pine-surge the human body with ultrasonic waves, it is important to bring the pine-surge part close to the hot water injection position. In order to achieve this, the present inventor developed a foaming device in which a hot water injection member is connected to the tip of a flexible hose. Since this foaming device injects hot water containing bubbles from the bottom of the bathtub, it is necessary to transfer the hot water containing air to the bottom of the bathtub. However, when hot water containing bubbles is transferred to the bottom of the bathtub using a flexible hose, the bubbles injected into the bathtub no longer efficiently generate ultrasonic waves. This drawback is due to the fact that fine air bubbles combine to form large air bubbles while being transferred through the hose, and the total number of air bubbles is significantly reduced. The generation efficiency of ultrasonic waves can be improved by mixing air with hot water at the tip of the hose and immediately spraying the hot water into the bathtub after the air is mixed.
To achieve this, an air hose is required to transfer air to the bottom of the bathtub, and two hoses are required, one for hot water and one for air. Moreover, this type of foaming device for bathing can be used extremely conveniently by detachably connecting the air hose and the hot water hose. In particular, foaming devices equipped with hot water injection pipes that spray hot water onto the water surface from above and generate ultrasonic waves from bubbles are used by switching the hot water injection position, so when hot water is not sprayed from the bottom of the bathtub, The air hose and hot water hose need to be removed. However, the foaming device requires two hoses,
There is a disadvantage that it takes a lot of effort to attach and detach the hoses, and that the hoses become bulky and get in the way when they are connected.

[Purpose of this idea]

This device was developed with the aim of eliminating these conventional drawbacks, and the important purpose of this device is to effectively generate ultrasonic waves by the bubbles injected into hot water, and to generate strong ultrasonic waves. To provide a foaming device for a bath, which can effectively massage the surface of the human body with sound waves and can easily and conveniently attach and detach a hose. Furthermore, another important purpose of this invention is to create a foaming device for bathing that allows the user to efficiently and effectively massage his or her desired location with ultrasonic waves that have a high therapeutic effect, without the need for a hose to get in the way. is to provide.

[Means to solve conventional problems]

The foaming device for baths of this invention includes a casing, a circulation pump disposed inside the casing and whose suction side is connected to hot water in the bathtub A via a suction pipe, and a coupling device to the discharge side of the circulation pump. and a foam ejecting member connected to each other via. The circulation pump sucks in hot water, and the hot water is injected into the hot water together with air by the bubble ejecting member, thereby injecting countless bubbles into the hot water. The foam ejecting member includes a flexible outer hose, one end of which is connected to the circulation pump via a coupling;
An air hose that is inserted into the outer hose, has one end connected to the atmosphere in a watertight manner, and is flexible enough to be deformed integrally with the outer hose; and an injection member that mixes air into the hot water sent from the outside hose and sprays bubble-containing hot water into the hot water of the bathtub.

[effect]

The foaming device for baths of this invention is shown in FIG. 1, which shows a preferred embodiment thereof, when a connecting pipe is inserted into the lower end of the water pipe connected to the discharge side of the circulation pump.
The air inlet end of the air relay pipe located within the connecting pipe is connected to the air outlet end of the lower end of the air supply pipe. When hot water is supplied from the circulation pump to the water pipe while the connecting pipe is connected to the water pipe, the hot water is sent through the connecting pipe and from the outer hose and the air hose to the air mixing and injection member. The air-mixing injection member injects hot water at high speed, sucks air under negative pressure due to high-speed flow, and injects air-mixed hot water. Air is drawn from the air supply pipe into the air relay pipe and from the air pipe is sent through the air hose to the air mixing and injection member. The air supply pipe, air relay pipe, and air hose are installed in the hot water passage, but because they are separated from the hot water passage, they are not mixed with the hot water during hot water transfer, and the air mixing injection member at the end of the hose It is then mixed with hot water and immediately sprayed onto the bottom of the bathtub. Therefore, in the foaming device for baths of this invention, air and hot water are separated from each other and transferred to the bottom of the bathtub using separate hoses, so that fine air bubbles do not combine during transfer with the hoses. An extremely large amount of microscopic bubbles are ejected, and these bubbles can efficiently generate highly therapeutic ultrasonic waves, which can effectively massage the surface of the human body. In addition, since the air hose is inserted into the hot water hose, it can be used conveniently with a single hose without being bulky or getting in the way.
