Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an in-bath foaming machine that generates a water stream and bubbles in hot water in a bathtub, and is intended to have a massage effect, a heating effect, and a cleaning effect.

Conventional configurations and their problems Conventionally, there are two types of bath foaming machines: olfactory type and jet type.

The olfactory type consists of a main body and a foam board.The main body is installed outside the bathroom, the foam board is sunk to the bottom of the bathtub, and compressed air is sent from the main body to the foam board through a hose. It cannot be closed, and since the foam board is fixed to the bottom of the bathtub, it has the disadvantage that you have to move your body to apply the foam to various parts of your body. In addition, the jet type is installed in the bathroom and draws its power from an outlet outside the bathroom, so there is a potential risk of electric shock, and in order to prevent this, the main unit becomes large and the bathtub becomes narrow. It has the disadvantage of becoming.
In order to deal with the problems of such conventional examples, the inventors
The foaming part body and the charging part body are provided separately, each is housed in a case and becomes independent, and when charging, the two are combined and charged by electromagnetic induction. Therefore, when in use, the foaming part body We have proposed a device that eliminates the drawbacks of conventional products by installing a chisel inside the bathtub.

With this configuration, there is no need to carry the charging unit into the bathroom, the foaming unit installed in the bathtub is made as small as possible, and easy to handle, and the power cord does not need to be drawn into the bathroom or bathtub. I was able to get rid of my worries about electric shock. However, since it is a product originally used in connection with bathing, even if it is a live part used outside the bathroom, there is a much greater chance of insulation deterioration due to water intrusion than other general electrical appliances.

Purpose of the Invention In view of the above-mentioned problems, the present invention has been designed to ensure the waterproofness of the main body of the live part, and to prevent the electrical parts from being waterproof even if the main body of the live part is accidentally splashed with water, or in extreme cases, even if it is thrown into a bathtub. A bath foaming machine with guaranteed sealing is provided.

Structure of the Invention In order to achieve the above object, the bath foaming machine of the present invention has a foaming section main body equipped with a storage battery, a control circuit, a motor, a charging secondary coil, etc., and a foaming section body equipped with a foaming spouting section. The charging section main body is configured to be detachable from the main body and charge the storage battery, and the charging section main body has a charging circuit section, and a charging circuit section inside the main body case.
It has a charging primary coil section, and these charging circuit section and charging primary coil section are sealed waterproof by bathing the upper and lower bags made of hard heat-resistant plastic, and a soft vinyl chloride welding tube is attached to the welding part of the power cord. This configuration makes the main body of the charging part completely waterproof.

DESCRIPTION OF EMBODIMENTS An in-bath foaming machine which is an embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a foamed part body, and 2 denotes a charging part body, in which electrical components are housed in plastic cases 3 and 4, respectively.

The foaming unit main body 1 has a storage battery 5, a control circuit 6, a motor 7, a pump 8, and a charging secondary coil 9 installed in a case 3.
The pump 8 is located at the bottom of the case 3 and is installed inside the water supply case 10. One end of water supply case 10 and case 3
A suction port 11 is provided at the bottom of the water supply case 10, and the other end of the water supply case 10 is connected to a foaming nozzle 12 facing outside the case 3. The lower end of the suction pipe 13 opened to the outside from the upper end of the case 3 is connected to the foaming nozzle 12, and when the pump 8 is operated, the suction port 11
Hot water sucked in from the foaming nozzle 12 is ejected from the foaming nozzle 12, and at this time, air is sucked in from the intake pipe 13 by the ejector action of the ejected hot water, and hot water mixed with air is ejected from the foaming nozzle 12. The secondary charging coil 9 is wound around the circumferential wall of a conical fitting recess 14 provided on the bottom of the case 3, and is electromagnetically coupled with the primary charging coil of the charging unit main body 2, which will be described later, to generate a secondary current. This is to induce power and supply power to the storage battery 5.

The charging unit main body 2 has electrical components including a charger circuit unit 15, a transmitting unit 16, and a reed switch 17 installed in a case 4.

These electrical components are housed inside the case 4, and in order to further ensure waterproofness, upper and lower bags 18a and 18b made of heat-resistant plastic are welded and sealed inside.
Charger circuit section 15, transmitter section 16 and reed switch 1
7 are arranged linearly, and seal portions 19 and 20 are also formed between the charger circuit section 15 and the oscillating section 16 and between the oscillating section 16 and the reed switch 17 to securely hold each electrical component. and perfect waterproofness. Upper and lower back 18a
, 18b, high frequency welding is used for the insertion part of the power cord 21 made of soft vinyl chloride, the welding surface is small, the welding length is short, and low output power, for example 0.6KW ~
Use a 1KW welding machine. This is to prevent induced current from flowing into the charger circuit section 15 via the power cord 21 and damaging the circuit when high-frequency welding is performed.
A welding tube 31 made of soft vinyl chloride is attached to the welding portion 21a of the power cord 21, and the welding tube 31 melts during welding, making it easy to weld the power cord 21 and the upper and lower bags 18a, 18b. It is preferable to use a high-power, for example, 5 to 7 KW high-frequency welding machine for the parts other than this power cord insertion part. In addition, the upper and lower backs 18a,
For the material 18b, a hard heat-resistant vinyl chloride resin is preferably used as a material suitable for high frequency welding, and in the example, a material having a plate thickness of 0.7wn was used.

The case 4 is composed of an upper case 4a and a lower case 4b,
Ribs 22a, 22b, 22c are provided at positions facing each other, and these ribs 22a, 22b, 22c are connected to the upper and lower back 1.
The ribs 22a, 22b, 22c are set to correspond to the outer seal portion and the inner seal portion 19 of the upper and lower backs 18a, 18b when the upper and lower cases 4a, 4b are connected, so that the ribs 22a, 22b, 22c of the upper and lower backs 18a, 18b are abutted against each other. Hold the seal part,
・Obtain solid support.

The upper case 4a is provided with a protrusion 23 around the periphery for stably placing the case 3 of the foamed part main body 1, and is fitted into a fitting recess 14 in which the charging secondary coil 9 of the foamed part main body 1 is provided. A conical fitting protrusion 24 is integrally formed therein, and the transmitter 16 is positioned within the fitting protrusion 24.

The transmitter 16 consists of a bobbin 25, a core 26 inserted into the bobbin 25, and a charging primary coil 27 wound around the bobbin 25.The core 26 is longer than the bobbin 25, so its lower part protrudes downward from the bobbin 25. I'm letting you do it.

This is to ensure heat dissipation from the oscillation section 16. The lower end of the core 26 is also used for positioning the oscillating section 16. The charger circuit section 15 is formed by connecting and supporting components to a printed circuit board 28, and the resistor 29, which has a particularly large temperature rise, is arranged at the bottom of the printed circuit board 28.
The distance between the upper surface of 8 and the upper back 18a is at least 5Tm.
This prevents damage to the upper and lower bags 18a and 18b due to heat. A magnet 30 is installed on the bottom of the case 3 of the foaming part main body 1 in correspondence with the reed switch 17 of the charging part main body 2, and when the case 3 is placed on the case 4, the reed switch 17 is Close.

This is to prevent damage caused by no-load driving caused by erroneous operation of the charging unit main body 2 alone. During the charging operation, the case 3 is placed on the case 4, the charging unit main body 2 is driven to operate the oscillating unit 16, and the magnetic inductive coupling between the charging primary coil 27 and the charging secondary coil 9 causes the storage battery 5 to be charged. Charge.

When in use, only the foaming part main body 1 is brought into the bathroom and placed in the bathtub. Effects of the Invention As is clear from the description of the above embodiments, according to the bath foaming machine of the present invention, the electric components housed in the case of the main body of the live part are waterproof sealed with upper and lower bags made of heat-resistant plastic, so that This guarantees complete waterproof performance even if the main body of the charged part is accidentally thrown into the bathtub.

In addition, the sealing properties of the power cords protruding from the upper and lower backs are more securely welded and highly waterproof due to the interposition of welding tubes. By considering the charging part main body, it was possible to separate the foaming part main body and the charging part main body, thereby ensuring the practicality and safety of the submerged foaming machine that utilizes magnetic induction.
