Inside the hot water tank 32, a siege heater 31 and a bimetal 14 having a function of shutting off power at high temperatures, and a temperature sensor 15 for detecting a temperature of water in the hot water tank and providing the control means to the hot water tank 32 were installed. An inlet and outlet pipe was installed in and out of the tank of water transferred through 17).

In addition to the inconvenience described above, because the bidet has a hot water tank (32) structure is not only bulky, but also difficult to install in the bathroom of a narrow space, wasteful space was a factor of the increase in production cost due to the complexity of the structure.

15 is a cross-sectional view of the washing water heating apparatus according to the prior art,

The hot water storage tank disclosed in Japanese Utility Publication No. 1-42757 (1989), the water transferred into the apparatus through the water inlet 40, is heated by the ceramic heater 34, which is an inflow passage, and is a space in the apparatus. Stored in the tank and has a float valve 43.

It is possible to supply hot water for continuous use, but it adopts a cylindrical ceramic heater, which is expensive for its material and consumes a lot of power in the heating method.

16 is a cross-sectional view of a washing water heater according to the new prior art,

It is registered in Korean Patent Publication No. 2001-0005931, which is similar in structure and operation to FIG. 15 but supplements the above problems. The water inlet 40 is located at the bottom and the water inlet 40 of FIG. 15 is a box-shaped cartridge. Insert.

The bottom surface of the cartridge inserted into the water inlet 40 is a flat ceramic heater 34, and the lid is made of copper (copper) having a good thermal conductivity.

The flat ceramic heater 34 is adopted to lower the unit cost of the material and to reduce the power consumption. On the other hand, the heater may be used to supply the washing water at an appropriate temperature (about 40 ° C) for continuous use as the apparatus of FIG. There is a problem in reducing the calorific value.

In addition, the structure is complicated, and it is a technology having an expensive structure in consideration of the metal housing, ceramic heater, and the like.

17 is a cross-sectional view of a second washing water heater according to a new prior art;

"Bidet with water direct heating heater" registered as Utility Model 20-0294079 (Registration date: October 22, 2002)

As shown in figure, direct instantaneous heating heater (PTC) is used by installing an inlet pipe, which is a passage for water, and its heater is composed of titanium barium trioxide (BaTiO3) and a small amount of dopant. It's called a kind of semiconductor,

PTC heater is the tinnitus of ceramic heater that is used all over the world. Its main ingredient is barium titanate exactly, and it uses a small amount of lanthanum, yttrium, bismuth, and turium depending on the use. Economic structure is expected.

18 is an exploded perspective view of a washing water heater according to a newer prior art,

19 is an exploded perspective view of a second embodiment of a washing water heater according to a newer prior art,

20 is a cross-sectional view of a newer prior art wash water heating device;

"BIDET" of Japanese Patent Publication No. 2004003371 (Application Date: 2003,08.22), "BIDET" of 2004003372 (Application Date: 2003.08.22), Domestic Application; 10-1999-7009008, Publication No .: 10-2004-0015377 No., 0015378, "Human Local Cleaner"

The structure has a simple structure that can not be seen in the prior art and the heating of the washing water is effective by heating by the plate-shaped ceramic heater 34 and has an air supply structure to the washing water by the air pump,

18, the body 35 of the resin component is held up and down, and the body has a meandering water passage 37 through which water flows on both sides of the body at the position where it is joined. It is bent more than once, and the water entering the inlet (40) of the body one side in the structure having the inlet (40) and the connector on the other side of the inlet (41) on one side of the body (35) is the primary circulation The heated and heated water exits the connector and is transported through the connector on the other side to circulate through the water passage 37 on the other side, and the secondary heating is completed and discharged through the outlet 41 to heat. Is completed.

Between both resin bodies, a ceramic heater 34 for heating the water flowing through the water passage and a silicon ring 36 for watertightness are provided.

Referring to the second embodiment of FIG. 19, a copper plate 44 having a high heat transfer rate is inserted in front of and behind the ceramic heater 34, and a silicon ring 36 is installed between the copper plate and the resin body.

The problem with this prior art is that

First, the water, which is the washing water that contacts the silicon ring 36 and meanders the water passage 37 in the body, is water pressurized by a pump to shorten the life of the silicon ring. Leakage occurs when the installation of the ring 36 or deformation due to the passage of time or vibration occurs, and leakage in the bidet to which power is applied has a safety problem.

Secondly, the resin body 35 is a resin component and has a low thermal conductivity, which is effective in preventing heat loss due to cooling, and heating according to continuous use of the ceramic heater 34 with a capacity of 1.2 Kw (spec details). It is possible to supply the washing water of about 40 ℃, but the water sprayed from the nozzle at the beginning should prepare water of 40 ℃ only by heating the ceramic heater 34. The heater 34 needs to be reheated and the number of times may be frequent, which is inconvenient due to flickering lights in a bathroom in which the user has a small amount of power, in particular a toilet in which the user is located.

(The water sprayed for several seconds at the beginning cannot be heated simultaneously with the operation of the ceramic heater. To maintain the temperature of the water sprayed from the initial nozzle at about 40 ℃, there is a method that has a heating time by delaying the start of spraying for several seconds after the operation by washing. There is a method of installing a seating sensor on the seat seated during stool and heating it before spraying to maintain the temperature.)

Third, the heater requires a lot of parts such as ceramic heater 34, copper plate 44, silicon ring 36, connector 42, which increases the price of the instantaneous heating device, making it difficult to adopt bidet and uneconomical The use of parts is likely to cause as many defects or malfunctions.

Fourth, the injection by the forced air pump in the injection of air to the wash water requires an air pump (not shown) in the bidet, there is a problem as described in the previous paragraph.

21 is a cross sectional view of a portion of a newer prior art resin body 35,

FIG. 22 is a vertical cross-sectional view of a portion of the resin body 35 in which a newer ceramic heater 34 or copper plate 44 and the resin body 35 are provided with the silicon ring 36 interposed therebetween,

FIG. 23 is a cross-sectional view showing the pressure by the newer prior art flowing washing water, FIG.

22, the ceramic heater 34 or the copper plate 44 and the resin body 35 are provided at a portion where the horizontal plane and the surface meet, but there is a gap therebetween, in order to prevent leakage caused by the gap. The lubricity groove will be installed in 35) and will be compressed and installed as shown in FIG.

In addition, the shape of the water passage (37) through which the washing water flows can be varied, but the shape of the pipe passage, which is a water passage, since the circular pipe can minimize pressure loss and wall friction loss than the respective pipes, so that the ceramic heater 34 or The water passage 37, which is a semi-circular pipe that can be adopted at the portion in contact with the copper plate 44, will be selected.

That is, the curved pipe flowing water having a semicircular cross-sectional area,

Looking at the flow of the curved tube, a pressure difference occurs in the cross-section CD of FIG. 23 due to the influence of the curved tube, the pressure drops on the inner part b of the curved tube, and the pressure increases on the outer part a.

Water of the outer wall portion of the water passage 37 is directed inwards along the wall surface, water near the central portion of the large velocity is pressed outwards. This flow is the secondary flow in the conduit (Secondary flow), the flow of the separation occurs according to this flow, which acts as a resistance of the flowing water.

Here, the pressure rises in the portion a of the water passage 37 and the pressure is transmitted to the portion a 'of the silicone ring 36 surrounding the outside thereof. The change in pressure of the b 'portion of the silicon ring is insignificant.

It is inevitable that deformation occurs in the silicon ring 36 according to the fatigue degree of the silicon when the pressure increase (at operation) and the decrease (at stop) are repeated only to a part of the silicon ring 36 which is an O-ring.

That is, the occurrence of leakage due to deformation of the silicon ring is inevitable.

In addition, the silicon ring 36 is installed in contact with the ceramic heater 34, which is a heating means, or the copper plate 44, which is a heat transfer path. Heating and cooling occur repeatedly, and the flowing water is pressurized before flowing into the main body. The deformed silicone ring 36 can be accelerated depending on the situation.

It only uses high quality silicone ring with high fatigue to extend deformation time.

The present invention has been made to solve the above problems, the purpose of the present invention is to improve the thermal efficiency, to ensure safety and to simplify the structure of the bidet to reduce the size of the bidet, because the use of a cheap sieve heater (Sheath heater) It is to provide a bidet having a cheap instant heating function by lowering the manufacturing cost.

The heating pipe 13 is a material corresponding to high heat and pressure during casting, and any material corresponding to a casting environment such as stainless steel pipe, steel pipe, brass pipe, or the like can be used.

Since the heater 12 generates heat in a state embedded in the main body 11, the generated heat is absorbed by the main body 11 at 100%. Heat absorbed by the main body is transferred to the water flowing in the heating pipe 13 embedded in the main body, and the heated water moves along the transfer pipe 17, which is a passage, and is discharged to the outside of the main body through the nozzle to circulate. Is completed.

The heat amount of the heater assembly of the present invention is proportional to the calorific value of the sheath heater,

The method of increasing the amount of heat the assembly has has been made by increasing the length of the heater to increase the heater capacity or by installing several heaters.

In order to economically increase the amount of heat, the long-length large-capacity heater is bent to reduce the length and install in the volume of the main body.

The bimetal 14 functions to cut off power supplied to the heater 12 when the main body is overheated, and is fixed to the outer wall of the main body 11.

The main body temperature sensor 15 detects the main body temperature and provides a function to the PCB circuit (not shown) as a control means and is fixed to the outer wall of the main body 11.

The transfer pipe 17 is a passage for transferring water from the water pipe to the heating pipe of the heater assembly.

The inlet temperature sensor 16 detects the temperature of the water entering the heater assembly of the present invention and the outlet water temperature sensor 18, which is a control means, sprays water from the nozzle to the human body at high temperature (50 ° C or higher) due to a failure of the component. This is to prevent the risk of burns.

When the sensor senses the temperature and transmits it to the PCB circuit, which is a control unit, the PCB circuit performs safety measures such as closing of the solenoid valve 19.

The PCB circuit, which is a control unit, heats the heater 12 in an ON / OFF manner in different ways depending on the difference between the temperature provided by the inlet temperature sensor and the desired temperature, thereby making water of a desired temperature.

The effect is maximized when several heaters 12 are installed in the main body 11.

4 is a cross-sectional view taken along the line B-B 'of FIG.

The inside of the main body 11 shows that the heater 12 and the heating pipe 13 are installed.

Heat generated by the heater embedded in the main body is absorbed by the main body 100% and the heat of the main body is transferred to the water circulating the heating pipe embedded in the main body.

5 is a cross-sectional view of the bending embodiment of the heating pipe according to the present invention;

6 is a cross-sectional view of the heater bending embodiment according to the present invention,

A heating pipe is installed inside the main body 11 and a heater inside.

This is to prevent the failure and fire of other parts of the bidet due to overheating of the outer wall of the main body generated when the heater is installed on the outside, and to prevent heat loss due to cooling.

7 is a cross-sectional view of the heater assembly having an instant heating function according to the present invention installed by buried in a heat insulating material,

The main body of the heater assembly is buried in the heat insulator 20.

This installation can minimize the heat loss of the heater assembly,

The heater assembly of the present invention adopts a circular pipe shape for the contact surface between the water and the heating element during heating, and minimizes the volume by bending and stacking the pipes.

For example, a space for installing 1m of 10 ° heating pipe (heater inside)

1) When the diameter of the volume is 10 cm (pipe diameter: 1 cm)

Circumference = Diameter X3.14 = 10X3.14 = 31.4Cm Both ends of external exposure 3Cm.

If you turn it three times, 31.4X3 = 94.2Cm, 94.2 + 6 (both ends) = 100.2 = 1m

In other words, a 1m heating pipe and a heater are installed in a volume of 11cm in diameter and 3cm in height.

2) When the diameter of the volume is 8cm (pipe diameter: 1cm)

Circumference = Diameter X3.14 = 8X3.14 = 25.12Cm Both ends of external exposure 3Cm.

If you turn 4 wheels, 25.12X4 = 100.48Cm, 100.48 + 6 (both ends) = 106.2 = 1m or more

In other words, a 1m heating pipe and a heater are installed in a volume of 9cm in diameter and 4cm in height.

If you adopt a rigid urethane foam as the heat insulator, in addition to the heat insulation effect that the urethane foam has,

1. Risk of leakage due to liquid entering and exiting the main body 11 of the assembly and having power applied to the entrance and exit port.

2. Malfunction due to detachment of fastening parts of heater assembly parts such as bimetal (14) and temperature sensor (15).

3. It prevents the leakage etc. which may occur in the joint part of the transfer pipe 17 and the heating pipe 13.

8 is a perspective view of a heater assembly according to a second embodiment of the present invention;

FIG. 9 shows a heating pipe and a heater installed inside the main body of FIG. 8 as a schematic diagram of the installation example of the heating pipe and the heater of FIG.

10 is a cross-sectional view of an installation example of the air supply structure according to the present invention

The bidet washes the body using water, and the start of washing is that the solenoid valve of the bidet is opened by the user's operation so that water is supplied to the nozzle and sprayed.

The end of the cleaning is to close the valve by operating the solenoid valve after a certain time injection.

Conventional technologies include "jet nozzles for bidets" in Publication No. 10-2004-0001801 (published date: 2004.01.07) and Utility Model Registration No. 20-0211444 (Registration Date: 2000, 11.13). Jet nozzle ".

The prior art is to drill an orifice perforation in the narrow part where the conveying tube is narrowed in the conveying tube of the nozzle tip (body) through which the washing water flows.

Drilling perforations in the transfer pipe is an unsuitable technique because water can spout through the perforations.

The air supply structure 23 of the present invention is installed in the transfer pipe 17 between the solenoid valve and the nozzle in an open structure in both directions, the installation is inserted into the end of the one direction of the air supply structure 23 into the transfer pipe The end of the structure within the feed pipe shall be installed in the direction of the nozzle.

The end of the air supply structure 23 outside the transfer pipe is exposed to the atmosphere.

When the bidet does not operate, the solenoid valve is closed so that there is no water between the solenoid valve and the nozzle and the transfer pipe, and the air supply structure 23 has no risk of leakage.

When the bidet is operated, the transfer pipe of the portion where the air supply structure 23 is installed is a venturi tube, and outside air is sucked into the transfer tube through the structure by the venturi effect.

In addition, the water flowing in the delivery pipe is reduced in cross-sectional area by the volume of the air supply structure 23, the flow velocity is increased, and the pressure decreases, and a sudden vacuum phenomenon (cavitation) occurs due to a sudden increase in the cross-sectional area. However, the air is sucked into the feed pipe and supplied to one end of the open air supply structure 23 instead of the wall.

Inhaled air is mixed with water, and it is sprayed through the nozzle with washing water having air bubbles (Air bubble) to increase the human washing effect.

11 is a schematic view of a second installation example of the air supply structure according to the present invention;

In order to increase the air supply amount of the air supply structure 23, the end of the air suction structure in the transfer pipe 17 is installed at a portion where the flow rate of the washing water is high.

If the flow velocity in the transfer pipe is constant, a resistor in the transfer pipe at the site of the end of the structure (22).

Here, theoretically looking at the intake of air in the air intake structure,

The pipe area of the feed pipe in the part where the air suction structure is installed is less than the cross-sectional area of the suction structure, so that the pipe area of the feed pipe in this part becomes smaller and the pipe area of the feed pipe after the end of the suction structure becomes the same as before.

That is, the transfer pipe of this part is a venturi tube and a hydrodynamic venturi effect occurs.

Resistor The reason for the installation of) (13) is Bernoulli's theorem: "When the flow rate increases, the pressure drops, and when the flow rate decreases, the pressure increases relatively." Open air supply structure increases the intake of external air by atmospheric pressure.

In addition, the relationship between the area of the pipe and the flow rate in the pipe through which a certain amount of water flows,

Part A: Area X Flow = Part B: Area X Flow

When the resistance is installed in the transfer pipe where the structure is installed, the pipe area is reduced, and the flow rate is increased in inverse proportion to the reduction ratio of the pipe area, and as the flow rate increases, the pressure drops in proportion to the amount of air sucked into the transfer pipe.

In addition, the method of installing the heater 12 and the heating pipe 13 in the hot water heater assembly of the present invention,

First, when casting the body, the end of the heater 12 and the heating pipe 13 in the body mold (mold) is inserted into the concave groove (insert hole; insert hole) of the mold, installed and cast to heat the heater and the inside of the body How to install a pipe.

Secondly, when the main body is cast, only the heater 12 is inserted into the main mold and the main body is processed after casting such as die casting to make a space that serves as a heating pipe in the main body.

Third, a method of making a heating pipe inside the main body by the two methods and inserting the heater (12) into the concave groove of the main body (11) or by installing by pressing.

Fourth, there is a method of applying the FLUX to the heater 12 and the heating pipe 13 and melting the flux flux by heat by brazing, thereby making the heater and the heating pipe integral. Here, the flux FLUX acts as the main body 11.

For example, the present invention can be changed in shape and shape, in particular, the present invention can be installed in the main body of the heater and the heating pipe in a different way as well as the modification installation of the heater and the heating pipe in addition to the above-described embodiment, claims Those skilled in the art without departing from the gist of the present invention claimed in the present invention that various modifications are possible, of course, such changes are within the scope of the claims of the present invention.
