The present invention relates to an air removing device for separating the air contained in the inflow water flowing into the main body by the diaphragm installed in the main body and the check valve installed in the main body and separated from the water.

At present, the heating method of the instantaneous hot water device is composed of a sheath heater made of iron and a stainless steel tube filled with iron chromium wire, which is a hot wire, with insulation such as magnesium oxide, and titanium barium trioxide (BaTiO3), and a small amount of dopant. There is a ceramic heater which is a type of N-type semiconductor to which (Dopant) is added.

For reference, ceramic heater is called direct instant heating heater (PTC: Positiv Temperature Coeifficient) and its main ingredient is barium titanate exactly, and a small amount of lanthanum, yttrium, bismuth, and turium are mixed according to the purpose.

Through the structural design of these two heaters, devices having the highest efficiency and economic efficiency are being developed one after another. Among them, the ceramic heaters, which have a high thermal efficiency by directly heating water, are used in heat exchangers. Especially, in the bidet, the water was heated and maintained at a constant temperature through the heater while having a large water tank. However, the power consumption is high and the efficiency is low. At present, the instantaneous hot water heat exchanger has reduced the internal space and improved the efficiency by directly contacting the water with the heater. The device is popular.

By the way, before entering the bidet's instant hot water device, the inflow water goes through an advanced filter (Ultra Filtration filter, Micro Filtration filter) to remove impurities and bacteria and have antibacterial effect. Air is mixed.

In addition, bidet can be divided into pump bidet and hydraulic bidet. In the case of pump bidet, water and air are completely separated by sufficient space inside water tank, but it is not a big problem for ceramic heater. In a bidet that warms water instantaneously by a hot water heater, there is not enough space, such as a water tank, so that air enters the ceramic heater with the water.

When the air mixed in the water comes into contact with the heating part of the ceramic heater in the instantaneous hot water device, only that part is locally overheated up to 300 ° C, which causes the ceramic heater to be broken or cracked. The built-in instantaneous water heater is less durable, and thus, the temperature deviation of the hot water from the instantaneous water heater is increased, and further technical design is required to stabilize this water temperature change, and the overall device structure becomes complicated and the unit cost increases. There is this.

The present invention has been made to solve the above-mentioned conventional problems, by separating the air contained in the influent water and discharged to the outside, to prevent partial overheating of the heater, and to reduce the temperature deviation of hot water from the instantaneous hot water device In addition, the object of the present invention is to provide a highly efficient air removal device having a simple structure and preventing the durability of the heater from falling over time.

The present invention for achieving the above object, the inlet pipe 11 and the outlet pipe 12 is the main body (1) formed on the outside in the order of up and down; A diaphragm 32 disposed transversely in the main body 1 between the inflow pipe 11 and the outflow pipe 12 and having a small hole; It consists of an air removing device which consists of a check valve 13 which is inwardly communicated with the upper part of the main body 1.

In addition, the main body 1 may be formed by being stacked in a multi-stage divided body, and the inlet pipe 11 extends into the main body 1, and the injection pipe 30 formed upward in a "b" shape. It is in communication with the inner end of the injection tube is expanded molding in a hemispherical shape.

In addition, the small hole of the diaphragm 32 has a diameter of 0.5mm ~ 1.0mm, the check valve 13 is opposed to the first check valve 14 in different directions so that the engaging projections (14b, 16b) are adjacent to And a second check valve 16.

When described in detail by the accompanying drawings of the present invention as described above are as follows.

1 is a perspective view of the present invention, Figure 2 is a plan view of the present invention, Figure 3 is a right side view of the present invention, Figure 4 is a cross-sectional view of Figure 3, (a) is a AA cross-sectional view, (b) is a BB FIG. 5A is an operating state diagram of the (b) check valve of FIG. 4, FIG. 5b is an operating state diagram of the (b) check valve of FIG. 4, and FIG. 6 is a view of the second check valve 16. A three-dimensional low shave, Figure 7 is a perspective view showing another embodiment of the present invention.

The present invention mainly consists of the main body 1, the first check valve 14, the second check valve 16, the discharge portion (8).

The main body 1 is a cylindrical cylinder, and has a top surface formed with an outflow passage 1a through which the inside and the outside communicate with each other while the lower portion is blocked, and has a fixing groove 23c on the outside and the first check valve. Main body flange (1b) for supporting the 14 is formed in the upper portion of the main body 1, the inflow pipe 11 is formed on one side of the lower surface of the outer surface of the main body 1, the inflow pipe outflow ( 12 is formed on the lower side of the outer surface of the main body 1 and below the inflow pipe 11, and is located horizontally in the main body 1 between the inflow pipe 11 and the outflow pipe 12. A diaphragm 32 is inserted which is punctured to allow water to pass but not to pass air.

In addition, the pores of the diaphragm 32 preferably has a diameter of 0.5mm ~ 1.0mm.

If the pore diameter is less than 0.5mm, the water coming in through the inlet pipe 11 hits the diaphragm 32 so that excessive pressure is applied, so that time is delayed in supplying constant water into the heater, and the water pressure drops. , If the pore diameter is more than 1.0mm, the diaphragm 32 is unable to separate the water and air, there is a problem that the air flows into the heater.

As shown in FIG. 4, the inlet pipe 11 extends into the inside of the main body 1 so that the whole is upwardly formed in a “b” shape and the inner end thereof is expanded in a hemispherical shape. And support ribs (R) which are capable of withstanding high water pressure.

In this case, the expanded molded concave shape of the injection pipe 30 is such that the water entering the inlet pipe 11 is wide spread to fall down so that water and air can be easily separated.

In addition, since the water flow is formed high by the pressure of the incoming water, the overall height of the main body 1 should be increased. However, since the height of the water is lowered by the concave shape, the size of the apparatus is reduced by lowering the overall height of the main body 1. This is efficient for bidets that have insufficient mounting space.

The first check valve 14 is composed of a first check valve casing 14a, a valve 14g, and a spring 14e.

The first check valve casing 14a is fitted to the inside of the main body flange 1b in the form of a vertical three-stage cylinder, as shown in FIG. 5A, with a fixed shaft 22c at the bottom and a fixing groove 23b at the top. Is formed, and a plurality of protrusions 14h having arbitrary lengths are formed on the inner circumferential surface of the first check valve casing 14a with a through hole 14f between the protrusions.

"이며 개폐역할을 하는 밸브판(14d) 및 상기 돌부(14h)의 하면과 상기 밸브판(14d)의 상면 사이에 끼워지는 스프링(14e)으로 이루어진다.The valve 14g is formed on the upper surface of the protrusion 14h so as to prevent the valve 14g from descending any further, and is formed at the lower portion of the locking protrusion 14b and the protrusion 14h. Valve shaft 14c having a vertical rod shape in close contact with the valve shaft 14 and a lower end of the valve shaft 14c.

And a valve plate 14d which serves to open and close, and a spring 14e fitted between the lower surface of the protrusion 14h and the upper surface of the valve plate 14d.

At this time, as shown in FIG. 5B, the repulsive force of the spring 14e is applied to the valve plate 14d when the pressure of the water charged in the main body 1 is applied to the valve plate 14d. It is designed to be in close contact with the first check valve 14 is switched from the open state to the closed state.

The second check valve 16 is composed of a second check valve casing 16a, a locking protrusion 16b, a valve shaft 16c, and a valve plate 16d having the same structure as the first check valve 14. It consists of a valve 16g and a spring 16e. However, the second check valve casing 16a is fixed to the first check valve casing 14a in a vertical two-stage cylindrical shape, and fixed shafts 22a and 22b are formed on an outer surface thereof, and a second check valve ( 16 takes a form opposite to the first check valve 14.

At this time, the repulsive force of the spring 16e is also shown in Fig. 5b, when the pressure of the water entering the outlet 9 is applied to the valve plate 16d, the valve plate 16e causes the second check valve casing 16a. It is designed to be in close contact with the second check valve 16 is switched from the open state to the closed state.

The discharge part 8 is formed at the center of the discharge pipe flange 10 and the upper surface of the discharge pipe flange 10 having a fixing groove 23a on the outside while being fitted to the outer surface of the second check valve casing 16a. The air filled in the main body 1 exits through the upper portion of the two-check valve 16 and consists of a discharge pipe 9 into which water enters the main body 1.

That is, in the present invention, the inlet pipe 11, the outlet pipe 12, and the main body 1 having the main body flange 1b are provided, and the fixed shafts 22a, 22b, 22c and the fixing groove 23a are provided. The first check valve 14 is inserted into the main body flange 1b through the 23b and 23c and the sealing 33, and the second check valve 16 is inserted into the main flange 1b. Combined in a snowy form.

Referring to the operating state of the present invention made of the above components as follows.

First, as shown in FIG. 4 and FIG. 5B, when water enters the inlet pipe 11, the water passes through the injection pipe 30 and ascends to the upper part of the inside of the main body 1, To fall. At this time, part of the air contained in the water is separated from the water.

On the other hand, the lowered water passes through the pores of the diaphragm 32, the air still contained in the water is separated from the water by the diaphragm 32 is collected in the upper body (1) and the water is the diaphragm 32 Passed down through the outlet pipe 12 is discharged.

In this case, since the outlet pipe 12 is connected to the instantaneous hot water device, the water from which air is removed through the air removing device of the present invention is introduced into the instantaneous hot water device. Here, the instant hot water device is a device that is provided with a heating element such as a ceramic heater to warm the water instantaneously.

At this time, the water passing through the instantaneous hot water device is heated to a certain temperature, in the case of bidet, the heated water is discharged through the nozzle. At this time, the pipe connected to the nozzle is also connected to the discharge pipe (9).

Therefore, a certain amount remaining after the discharge through the nozzle and stops operation can be flowed back to the instantaneous water heater or back through the discharge pipe, a separate check valve in the instantaneous water heater to prevent backflow to the instantaneous water heater. Is provided is discharged through the actual nozzle and the remaining water in the pipe is to be introduced back into the discharge pipe (9).

Although the discharge pipe 9 is not shown in the drawing with respect to the operation of the check valve 13, since it is formed in the form connected to the pipe from the instantaneous hot water device, if the pressure in the main body 1 is always a slight time difference (main body (1) after the water has passed through the secondary outlet pipe 12 to the discharge pipe 9), the pressure is also applied to the discharge pipe 9 so that the first check valve 14 closes the second check valve. Interlock with (16) also closes. In other words, when both are normally open and pressure is applied to the inside of the main body 1, pressure is also applied to the discharge pipe 9 at the same time so that both the outlet pipes 12 are closed at the discharge pipe of the instantaneous hot water device. 9) should be connected.

In addition, the operation of the present invention with respect to the use of the bidet is applied as follows:

When the user presses the nozzle injection switch after looking at the toilet, as shown in FIGS. 4 and 5B, the air should not enter the inside of the main body 1 filled with water more than the height at which the inlet pipe 11 is located. When water starts to enter the main body 1, the air in the upper part of the main body 1 is discharged to the discharge pipe 9, and when the water is filled, the upper part of the main body 1 through the inlet pipe 11 and the injection pipe 30 Most of the widespread water descends, and part of the water spreads downwards after applying pressure to the valve plate 14d, and the first check valve 14 is closed, and the lowered water flows out with air separated through the diaphragm 32. Exit to coffin 12. The water exiting the outlet pipe 12 exits to the outlet pipe 9 branched from the nozzle and the pipe leading to the nozzle via the instantaneous hot water device. Accordingly, the water entering the discharge pipe 9 pressurizes the valve plate 16d so that the second check valve 16 is kept closed.

 At this time, the air naturally separated from the water spreading widely above the main body 1 and the air injured due to the diaphragm 32 remain together with the filled water.

Then, when the user stops using the nozzle, as shown in FIG. 5A, the water filled in the main body 1 does not enter the inlet pipe 11 and exits the main body 1 while the water is filled in the outlet pipe 12. Air remaining in the air expands and at the same time the pressure applied to the valve plate 14d is dissipated so that the first check valve 14 is opened by the spring 14e, and the water is not transferred to the outlet pipe 12. The pressure of the water introduced into (9) is not applied to the valve plate 16d so that the second check valve 16 is opened by the spring 16e.

At this time, the air remaining in the upper portion of the inside of the main body 1 is sequentially opened while the first check valve 14 and the second check valve 16 are open, the outlet passage 1a, the valve 14g, and the first. After passing through the space between the check valve casing (14a) and the through hole (14f), and finally through the discharge pipe (9) through the space between the through hole (16f), the valve (16g) and the second check valve casing (16a), at the same time The water in the remaining pipe used through the nozzle and the water flowing from the discharge pipe 9 flow into the main body 1 and merge with the remaining water in the main body 1 so that the inlet pipe 11 is above the height where the main body 1 is located. The water always fills up.

In this way, when water enters the inlet pipe 11, the first check valve 14 and the second check valve 16 are in a closed state, so that the air is naturally separated or separated through the diaphragm 32 is the main body. (1) If the water remains in the upper portion of the inside of the inlet pipe 11, the first check valve 14 and the second check valve 16 is open to the upper portion of the inside of the main body (1) The remaining air is discharged to the discharge pipe (9) and the water is repeated to enter the body (1) through the discharge pipe (9).

In addition, in order to prevent backflow due to the normal operation and siphon phenomenon, when the present invention is installed in the instantaneous water heater, the air removing device is designed to be lower than the height of the tank containing a lot of water such as a float valve in the instantaneous water heater of the bidet. Should be.

For reference, FIG. 6 shows a coupling state between the through hole 16f, the protrusion 16h, the spring 16e, the valve 16g, and the second check valve casing 16a, which are components of the second check valve 16. have.

On the other hand, the main body 1 may be molded integrally, but a multistage divider, such as a two-divided body, a four-divided body, an eight-divided body which can adjust the height of the body 1 variably according to the use and application conditions of the present invention It can be made by combining.

For example, as shown in FIG. 7, the quadrilateral body is open only at the upper part with the lower part blocked, and the first division body 40 having the outlet pipe 12 through which the inflow water exits is formed on one side of the outer surface, and the upper and lower parts are opened. And a second dividing body 41 having the same internal diameter as that of the first dividing body 40 and having an inflow water therein, wherein the inlet pipe 11 is formed at one side of the outer surface of the first dividing body 40 and the first dividing body ( The third partition 42 and the second partition 42 having a small hole perforated therebetween 40 and the second partition 41 are installed on the second partition 41 and the upper and lower portions are open. The upper surface is formed on the three-split body (42), the upper surface is formed with the outflow passage (1a), and the main flange (1b) for supporting the first check valve 14, the fixing groove (23c) is the upper surface It consists of a fourth divided body 43 formed upward.

The coupling between the partitions 40, 41, 42, 43, the first check valve 14, the second check valve 16, and the discharge pipe flange 10 is formed on the inner and outer surfaces of the integral molding, interference fitting, and abutting parts. The formed screw thread, the fixing piece provided separately, the hinge protrusion and the hinge groove, may be by a combination of bolts and nuts, screws and the like.

In addition, the check valve 13 can be replaced by a solenoid valve capable of precise opening and closing function by electrical control, the present invention is not only for the instantaneous hot water device of the bidet but also for the instantaneous hot water device of the boiler such as a ceramic heater It is possible to use all the purpose of removing the air of the inflow water to the heater that the problem occurs when entering, and can be used in the industrial field, medical field, experimental field, etc. to remove the air in pure water.

In the above, the present invention is not limited to the described embodiments, and various modifications and changes are possible within the technical spirit of the present invention.
