Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a Yunaka foaming machine that generates water flow and bubbles in hot water in a bathtub, and is intended to have a massage effect, a heating effect, and a cleaning effect.

Conventionally, Yunaka foaming machines are known as a blowing type and a jet type.

The warm air 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 these problems of the conventional method, the inventors separated the foaming part body and the charging part body, placed them in a case to make them independent, and when charging, connected them and charged them by electromagnetic induction. The present invention proposes a system that eliminates the drawbacks of conventional products by installing only the foaming part body in the bathtub during use.

With this configuration, there is no need to bring the charging unit into the bathroom, the foam unit that is installed in the bathtub is made as small as possible, and easy to handle, and there is no need to run a power cord into the bathroom or bathtub. This eliminates concerns about electric shock accidents. The present invention is designed to ensure the waterproofness of the main body of the live part in such a structure, so that even if the main body of the live part is accidentally splashed with water or, in extreme cases, thrown into a bathtub, the waterproof seals of the electrical parts are protected. It is intended to be guaranteed.

Because this product is originally used in connection with bathing, there is a much greater chance of insulation deterioration due to water intrusion than other general electrical appliances, even if the live parts are used outside the bathroom. It is consideration. Embodiments 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 part 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 foaming nozzle 12 is connected to the lower end of the suction pipe 13 which is connected to the outside from the upper end of the case 3, and when the pump 8 is operated, the suction port 1
The hot water sucked in from the foaming nozzle 12 is ejected from the foaming nozzle 12, 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 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. , and supplies power to the storage battery 5. The charging unit main body 2 includes a charger circuit unit 15 in the case 4,
Electrical components including a transmitter 16 and a reed switch 17 are installed.

These electrical components are located inside the case 4, and in order to further ensure waterproofness, upper and lower packs 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 transmitting section 16 and between the transmitting section 16 and the read switch 17 to securely hold each electrical component. and perfect waterproofness. Upper and lower pack 18a,
High frequency welding is used around the power cord 21, but the welding area is small and the welding length is short at the insertion part of the power cord 21.
Low output, for example 0. Use a welding machine for rudders W to IKW. This is to prevent induced current from flowing into the charger circuit section 15 through the power cord 21 and causing damage to the circuit when performing high-frequency welding. 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. The upper and lower packs 18a and 18b are preferably made of hard heat-resistant vinyl chloride resin as a material that has been subjected to high-frequency welding, and in this embodiment, a material having a thickness of 0.7 is 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 form the upper and lower packs 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 packs 18a, 18b, and when the upper and lower cases 4a, 4b are combined, the ribs 22a, 22b, 22c are butted against each other, and the upper and lower packs 18a, 18b are Hold the seal part,
Gain solid support.

The upper case 4a is provided with a protrusion 23 around the periphery for stably mounting the case 3 of the foamed part main body 1, and is fitted into a recessed part 14 in which the charging secondary coil 9 of the foamed part main body 1 is provided. A cone-shaped mating protrusion 24 is integrally formed therein, and the transmitting part 16 is located within this mating protrusion 24.

The transmitter 16 is composed 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, and therefore its lower part protrudes downward from the bobbin 25. I'm letting you do it.

This is to ensure heat dissipation from the transmitter 16. Further, the lower end of the core 26 is also used for positioning the transmitter 16. The charger circuit section 15 is formed by connecting and supporting components to a printed circuit board 28. A resistor 29, which has a particularly large temperature rise, is arranged at the bottom of the printed circuit board 28, and
A distance of at least 5 skins between the upper surface of the pack 8 and the upper pack 18a is ensured to prevent damage to the upper and lower packs 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 IJ switch 17 of the charging part main body 2, and when the case 3 is placed on the case 4, the magnet 301 will cause the reed switch 17 to to open. This is to prevent damage caused by no-load driving caused by erroneous operation of the main body 2 of the charging section alone. During the charging operation, the case 3 is placed on top of the case 4, and the charging unit main body 2 is driven to operate the transmitting unit 16.
The storage battery 5 is charged by magnetic inductive coupling between the primary charging coil 27 and the secondary charging coil 9.

When in use, only the foaming part main body 1 is specially placed in the bathroom and installed in the bathtub. The present invention provides upper and lower packs 18a made of heat-resistant plastic for electrical components housed in the case 4 of the main body 2 of the charging section.
, 18b, complete waterproof performance is guaranteed even if the main body 2 of the charging part is accidentally thrown into the bathtub.

By considering the charging part main body, the foaming part main body and the charging part main body are separated and magnetic induction is used to ensure the practicality and safety of the submerged foaming machine.
