Description

{Instantaneous hot water system with improved bubble discharge}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an instantaneous hot water supply apparatus for improving bubble discharge, and more particularly, to a bubble discharge apparatus capable of preventing a water- The present invention relates to an improved instantaneous hot water apparatus.

In general, the heating method of the instantaneous hot water device is mainly composed of a sheath heater made of iron or a stainless steel tube and a titanium barium trioxide (BaTiO 3) filled with a heat-resistant iron nichrome wire with a heat insulating material such as magnesium oxide, There is a ceramic heater which is a kind of N-type semiconductor doped with pentafunction.

Among them, a ceramic heater is called a Positive Temperature Coefficient (PTC) and its main component is barium titanate, and a small amount of lanthanum, yttrium, bismuth, and thorium is used depending on the application.

These two heaters are being developed to improve efficiency and economy through structural design. Among them, since the heating action is directly performed on the water, a ceramic heater having a high thermal efficiency and energy saving effect is widely applied in the heat exchanger.

In particular, in the case of bidets, water was heated and maintained at a constant temperature through a large water tank and a separate heater. However, since the power consumption is high and the efficiency is low, recently, the water is directly contacted with the heater, A large number of instantaneous heat exchange heat exchangers have been applied.

The bidet is passed through an advanced filter such as an Ultra Filtration filter or a Micro Filtration filter to remove impurities and germs before the inflow water enters the instantaneous hot water device. In this process, the inflow water passes through the filter particles, Is mixed.

Also, the bidet can be largely divided into a pump type and a water pressure type. In the case of a pump type, the water and the air are completely separated from each other by a sufficient space inside the water tank, In a bidet that instantly warms water, there is not enough space like a pump-type water tank, and the air enters the ceramic heater together 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, there is a problem that the ceramic heater is overheated locally to 300 ° C and the ceramic heater is cracked or cracked. There is a problem that the durability of the instantaneous hot water apparatus in which the built-in water heater is built is inferior.

On the other hand, even in the case of various water purifiers, it is necessary to heat the low-temperature raw water to high-temperature high-temperature water within a short time, and therefore, the instantaneous hot water apparatus using a ceramic heater is widely applied.

However, various water purifiers employing ceramic heaters have problems such as water burning due to unstable water flow, resulting in burning of the user, when the high temperature water heated through the heating member is taken out together with a large amount of bubbles.

BRIEF DESCRIPTION OF THE DRAWINGS The above and other objects, features and advantages of the present invention will be more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: FIG.

1 to 4, the instantaneous hot water apparatus according to the embodiment of the present invention includes a water inlet 20 and a water outlet 30 connected to each other, And a chamber 40a.

Further, the instantaneous hot water apparatus of the present invention can be configured to measure and control the flow rate of the raw water supplied through the water inlet 20, with a separate PCB controller 10.

That is, the water inlet 20 may include a flow control valve 11 and a flow rate measuring sensor 12 connected to a separate PCB controller 10.

The inlet portion 20 is connected to one side surface of the heating chamber 40a. And the water outlet 30 is connected to the other end side surface of the heating chamber 40a.

A predetermined heating member 40 is inserted and mounted at one end portion of the inlet portion 20, that is, inside the lower end surface of the heating chamber 40a.

Here, the heating member 40 forms an internal heating passage 41 having one end closed and the other end opened in the shape of a predetermined pipe, while the external heating (heating) member 40 is inserted into the heating chamber 40a, And the flow path 42 is formed.

The heating unit 40 is heated by the heating unit 40 while the raw water supplied through the inlet unit 20 passes through the internal heating channel 41 and the external heating channel 42 in the form of a predetermined hose structure, And then flows out of the predetermined gas.

The heating chamber 40a is joined with an outflow member 50a including a bubble storage portion 50 at the opposite end to which the heating member 40 is inserted. The bubble storage part 50 is formed in a cup shape which is laid down.

That is, in the instantaneous hot water apparatus of the bubble release improvement type according to the embodiment of the present invention, predetermined raw water is supplied from the internal heating passage 41 of the heating chamber 40a and the ceramic heater type heating member 40 and the external heating passage 42 The air particles contained in the water are separated from each other while being heated by the hot water. In consideration of the fact that the bubbles have a specific gravity smaller than that of water and have a property of rising upward, it is possible to take a form in which the outflow member 50a including the bubble storage part 50 is disposed at the upper end of the heating chamber 40a.

The bubble storage portion 50 of the water outlet member 50a is constituted by a plurality of inner space division type blocking films 51 and an annular cylindrical body 52.

The inner space-dividing shielding film 51 and the annular cylindrical body 52 are connected to each other through a plurality of inner upper surfaces and inner wall surfaces of the water outlet member 50a.

The bubble storage part 50, that is, the predetermined blocking film 51 and the annular cylindrical body 52 form a predetermined space higher than the water level of the high-temperature water, and bubbles rising from the high- Take a role.

The arrows indicated by the solid line in FIG. 4 arbitrarily show the movement of the bubbles generated while the raw water changes from the heating member 40 to the high temperature water.

It is preferable that the cylindrical body 52 of the bubble storage unit 50 is made to match the shape and diameter of the heating member 50 so as to advantageously store the generated bubble in a short period of time. For example, if the heating member 50 is in the form of a cylindrical pipe, at least one of the cylindrical members 52 of the bubble storage unit 50 may be formed in a cylindrical shape having the same diameter as that of the cylindrical member of the heating member 50.

The blocking membrane 51 of the bubble storage unit 50 blocks the bubble stored in the bubble storage unit 50 from being directed to the water outlet 30. When a large amount of air bubbles are accumulated in the bubble storage unit 50, the air bubbles are condensed with water droplets and flowed down through the wall surfaces of the plurality of barrier membranes 51 or the annular cylindrical body 52, . ≪ / RTI >

The bubble storage portion 50 of the water outlet member 50a minimizes the occurrence of bubbles during the outflow of the hot water, thereby reducing the measurement deviation of the outflow temperature sensor 14 and maintaining the outflow water flow rate and shape constant, And obtaining a technical effect such as planning.

In addition, the method of removing air bubbles using a check valve is disadvantageous in that the heat loss due to the discharge of air bubbles is increased, and the stiffness is complicated. However, the structure of the outflow member 50a according to the embodiment of the present invention does not directly discharge high-temperature bubbles but simplifies the structure of the heating chamber 40a and the water outlet 30, .

On the other hand, the outflow member 50a is provided with an insertion port 50b for connection with the water outlet 30. Here, the insertion port 50b is formed below the bubble storage part 50, and is a kind of flow path passing through the inside and outside, preferably in the form of protruding onto the outer surface of the outflow member 50a.

The heating member 40 disposed in the heating chamber 40a has a shorter overall length than the heating chamber 40a. That is, the end of the heating member 40 is provided in a state in which the end of the heating member 40 is spaced less than the joining boundary end of the heating chamber 40a and the outflow member 50a.

The coupling structure of the heating chamber 40a and the heating member 40 according to the length of the heating chamber 40 may be formed by connecting the water outlet 30 to the water level changing into the high temperature water through the internal heating channel 41 and the external heating channel 42, It is easy to keep the insertion port 50b connected to the water outlet 50a at a level where the water inlet 50b is connected to the water inlet 50a.

A seal 50c for preventing water leakage may be further provided between the heating chamber 40a and the water outflow member 50a.

The heating member 40 having a predetermined pipe shape has inner and outer through holes 43 formed therein. The inner and outer through holes 43 are preferably formed at positions facing the communication holes 40b of the heating chamber 40a leading to the inlet portion 20. [

The bubble elimination improvement type instantaneous hot water apparatus according to the embodiment of the present invention is characterized in that the flow rate of the raw water is more likely to be guided by the external heating flow path 42 than the internal heating flow path 41, And at the same time, the heating efficiency is improved.

The end of the heating member 40 on the side where the inner and outer through holes 43 are formed is closed and the other end of the heating member 40 disposed on the side of the water outlet 30 is formed in the form of an open pipe- .

The heating member 40, which is a ceramic heater, includes a predetermined heating wire 44. At this time, the heat line 44 is surrounded by the outside of the body of the heating member 40, which is a ceramic heater, or is placed close to the outer side, so that the heating efficiency of the raw water flowing along the external heating channel 42, Is higher.

The present invention is designed to focus on the technical characteristics of the heating member 40 as described above.

The cross sectional area of the inner heating passage 41 in the heating chamber 40a may be smaller than the cross sectional area of the outer heating passage 42. [

Furthermore, the heating chamber 40a may be provided with a predetermined flow induction shielding film 40c between the communication hole 40b and the inner and outer through holes 43 of the heating member 40. [

The flow rate guiding shielding film 40c can be implemented in the form of a horizontal barrier which is biased in a direction along the external heating flow path 42 from the communication hole 40b.

At this time, the flow guiding shielding film 40c serves to prevent the raw water flowing through the communication hole 40b from directly flowing into the inner and outer through holes 43. At the same time, the flow guiding curtain 40c circulates a predetermined number of times along the outer wall surface of the heating member 40, that is, the outer heating passage 42, and passes a predetermined raw water through the inner heating passage 41 through the inner and outer through holes 43 .

Through this process, the flow guiding curtain 40c serves to induce the flow of the raw water to the external heating passage 42 more than the internal heating passage 41, so that the flow of the external heating passage 42 The flow rate is increased to ultimately obtain the technical effect of shortening the heating time of the raw water and increasing the heating efficiency.

In addition, an inlet temperature sensor 13 may be provided between the communication hole 40b of the heating chamber 40a and the inlet 20. Further, an outflow temperature sensor 14 may be further provided between the other end surface of the heating chamber 40a and the water outlet 30.

The inlet temperature sensor 13 and the outlet temperature sensor 14 measure the temperature of the raw water supplied through the inlet section 20 in conjunction with the separate PCB control section 10, The temperature of the hot water heated in the heating flow path 42 can be measured at the inlet end of the water outlet 30.

The intake temperature sensor 13 and the outflow temperature sensor 14 can control the related items such as the flow rate of the raw water more precisely according to the temperature of the high temperature water requested by the user from the separate PCB controller 10 And so on.

The instantaneous hot water apparatus of the present invention can be applied to various water purifiers such as domestic and business use. And the flow rate for raw water supply is measured and controlled from the separate PCB controller 10 through the water inlet 20.

At this time, the flow rate control and measurement of the raw water is performed by the flow rate control valve 11 and the flow rate measurement sensor 12 of the water inlet 20.

The raw water supplied from the inlet portion 20 is guided to the outside by the flow rate induced shielding film 40c between the communication hole 40b and the inside and outside through holes 43 while passing through the communication hole 40b of the heating chamber 40a. And is guided along the heating flow path 42.

After that, that is, the predetermined raw water flows into the internal heating passage 41 through the external wall surface of the heating member 40, that is, the external heating passage 42 and then through the internal and external through holes 43 .

At this time, the transverse sectional area of the external heating passage 42 is wider than the transverse sectional area of the internal heating passage 41 at the same point on the horizontal line, and the flow rate of the raw water is larger than the internal heating passage 41, The flow rate of the gas is increased.

On the other hand, in the heating member 40, the heat ray 44 is formed closer to the external heating flow path 42, and the heat generation performance is further actively directed toward the external heating flow path 42.

Therefore, according to the instantaneous hot water supply apparatus of the bubble discharge improvement type according to the embodiment of the present invention, the technical effect of improving the heating efficiency, such as shortening the heating time for switching the raw water to high temperature water, is obtained.
