Description

Hot water supply device for smooth circulating water supply {HOT WATER SUPPLY}

The present invention relates to a hot water supply device, and more specifically, in the hot water supply device for circulating and supplying hot water to a hot water mat or a poultice pack, a filter part is installed to induce smooth hot water circulation by filtering impurities that may occur during the circulation process. In addition to the simple filter function to filter out impurities due to the unique structure of the unit, it is possible to reduce the noise when operating the device by dispersing the wavelength of the noise generated during the circulation of hot water. The present invention relates to a hot water supply device that allows the circulation water to be supplied smoothly without overwhelming the device.

In the past, there were many products using heating wires such as electric mats and cushions so that products requiring warmth such as mats and cushions can be heated immediately at a desired time.

However, in recent years, there is a constant risk of fire or electric shock due to harmful electromagnetic waves and heat generation or short circuits of heating wires, and as interest in health increases, hot water circulating through hot water circulating through circulation pipes instead of heat using electricity. Demand for mats and poultice packs is increasing.

As such, in order to supply hot water to a mat or a steam pack through a circulation pipe, a hot water supply device having a pump for heating the water stored in the reservoir with a heater and circulating the water of the reservoir (circulating water) through the circulation pipe is required.

When the conventional hot water supply device is operated, the pump continuously supplies the circulation water of the reservoir to the circulation pipe. At this time, a small centrifugal small pump is mainly used as a configuration for discharging the circulation water to the circulation pipe. Due to the high noise generated by the rotation of the hot water mat used in particular, there is a limit that the commerciality is poor.

The hot water supply apparatus using a check valve for discharging the circulating water by using the pressure of the circulating water in place of the centrifugal compact pump is proposed in the configuration for discharging the circulating water to the circulating pipe. .24) "Hot water circulation device", Patent No. 10-0969815 (2010.07.06) "Noise reduction type hot water supply device", and the like.

Among them, Patent No. 10-0876939 uses a check valve rather than a centrifugal compact pump, so it has a noise attenuation effect compared to a hot water supply device employing a conventional centrifugal compact pump. There is a limit to expect a high noise attenuation effect because there is no separate structure for controlling the collision with the circulating water or the internal structure when opening and closing the check valve fixed on one side.

In addition, Patent No. 10-0969815 is a structure designed to compensate for the limitation of Patent No. 10-0876939, but has an advantage that a higher noise attenuation effect can be expected than Patent No. 10-0876939, The salt attenuation structure disclosed in 0969815 can only expect a noise attenuation effect, but also has a limitation in that it can not be expected together with the effect of removing the debris, which can be generated during circulation, as impurities mentioned in the present invention. .

Therefore, the present invention is designed to solve the problems or limitations of the existing hot water supply device as described above, and a hot water supply device having a filtering part capable of anticipating a noise prevention effect while filtering wastes generated during circulation of the circulating water by a simple structure. The first thing to do is to provide.

The upper check valve in the reservoir is characterized in that the technical portion is provided with a plurality of through holes formed.

In addition, the filter portion is made of a cross-section of the upper and lower light shape, or is made of a shape that becomes larger again after the cross-section is smaller toward the bottom, the upper and lower portions of the filter portion is characterized in that the packing is provided.

In addition, the valve body according to the present invention,

It consists of a fastening shaft formed with a locking portion for fastening with the frame, the valve membrane is connected to the fastening shaft,

The valve membrane is characterized in that the weak part is formed to induce the smooth opening and closing of the valve membrane.

According to the hot water supply device having the above configuration can be expected to have a noise prevention effect as well as filtering the debris generated during the circulation of the circulating water by having a filtering portion designed in a simple structure inside the reservoir.

By introducing a structure in which the circulating water is introduced into the check valve in the longitudinal direction rather than the existing transverse direction, the opening and closing operation of the check valve is smoothly performed, and thus, a hot water supply device capable of smoothly circulating the circulating water is obtained. .

Furthermore, due to the specific structure of the check valve shaft and the valve membrane of the check valve introduced in the present invention, it is possible to induce a smooth opening and closing of the check valve.

Eventually, there is an effect of obtaining a hot water supply device that can expect a smooth supply of circulating water.

Hereinafter, the hot water supply device according to the present invention will be described in more detail with reference to the accompanying drawings.

1 and 2 is a view showing a hot water supply apparatus employed in the aforementioned Patent No. 10-0969815 and the like except for the internal structure of the reservoir having a check valve is the same as the present invention Figures 1 and 2 The operation relationship of the parts except for the internal structure of the reservoir in which the check valve is provided will be described.

As shown in FIGS. 1 and 2 (FIG. 2 is an exploded view of the hot water supply device in an inverted state with reference to FIG. 1), the hot water supply device includes a reservoir 40, a heater 30, and a nozzle ( 51 or 56), the check valve 60, and the case 10 is built to protect them to provide hot water to the hot water mat (2) and the poultice pack (1).

For reference, the hot water supply device illustrated in FIGS. 1 and 2 has a structure capable of supplying hot water to two objects, such as a hot water mat 2 and a poultice pack 1. The nozzle may include a first nozzle 51 and a second nozzle ( 56) Although two are provided, depending on the manufacturing, it may be provided with more than the nozzle, or only one may be provided.

In addition, a controller (not shown) for controlling the operation of the heater is built in one surface of the case 10.

Next, the case 10 is assembled with the upper case 11 and the lower case 12 are assembled and coupled, the upper surface of the upper case 11 is provided with a cap 20 and an operation unit connected to the controller,

The upper surface of the upper case 11 is in communication with the opening of the reservoir 40 is formed with a circulating water inlet 19 for replenishing the circulating water, the cap 20 is fastened to the inlet (19).

In order to seal the opening of the reservoir to prevent spontaneous evaporation of the circulating water, an inner surface of the upper case 11 covers the opening of the reservoir 40 and an inner case of the upper case covering the opening of the reservoir 40 is provided with a packing tank and the upper portion. Seal the gap of the contact surface of the case.

However, the difference between the structure of the reservoir and the case of the conventional hot water supply device and the reservoir 40 and the case 10 of the present invention described below is a structure in which the cap 20 is directly coupled to the opening of the reservoir in the present invention. Is designed.

In other words, even if the cap is fastened to the case despite the portion where the circulating water is stored, not the inside of the case, even if the contact surface of the reservoir opening and the upper case is well sealed, there is a risk that the sealing force drops and the circulating water may leak.

Accordingly, in the present invention, as shown in FIG. 3 or less, in the present invention, the cap 20 is designed to be directly coupled to the reservoir 40 so that the circulating water in the reservoir 40 flows toward the case, thereby heating the heater 30 and the like. It eliminates the risk of affecting the internal structure.

Next, the heater 30 provided in the case 10 is connected to the discharge path O through which the circulating water is discharged from the reservoir 40, thereby heating the discharged circulating water.

In addition, the heater 30 is installed on the conduit 93 connecting the reservoir 40 and the nozzles 51 and 56 to minimize contamination of the circulation water due to corrosion or scale, and for convenience of maintenance.

The heater 30 is made of an aluminum material having excellent thermal conductivity, an anodized film is formed on the surface through surface treatment, and a metal of acetate or sulfate is deposited on the anodized film. Since silver or copper, or silver and copper are deposited on the surface of the anodized film on the surface of the heater through the surface treatment, antibacterial, deodorant, and thermal conductivity are increased to prevent contamination of the circulating water and to be heated faster.

The surface treatment of the heater is performed by putting a heater into an electrolyte solution in which a metal acetate (copper acetate or copper acetate) or a metal sulfate (sulphate or copper sulfate) is added to a sulfuric acid bath, a fish bath or a mixed bath thereof, and a pulse wave current is applied to the electrolyte solution. It is carried out by the method of electrolytic treatment.

In addition, in the first nozzle 51 and the second nozzle 56, one side of the connecting portions 52 and 57 is embedded in the case 10, and the other side of the connecting portions 52 and 57 is exposed to the case 10. It is mounted to the case 10, one side of the connecting portion 52, 57 is connected to the conduit 93, the other side of the connecting portion 52 57 is connected to the circulation pipe 95, respectively, the hot water mat (2) and the hot pack (1) Circulating water is supplied to

And the circulating water circulated through the hot water mat (2) and the hot pack (1), respectively, is introduced into the first nozzle and the second nozzle (51, 56) on the opposite side, and the inlet path (I) through the pipe line 93 is not connected to the heater (I) ) Into the reservoir.

Next, with reference to Figures 3 and 4 will be described with respect to the reservoir (40) and the check valve 60 provided inside the reservoir of the core of the present invention.

The reservoir 40 and the check valve 60 according to the present invention shown in Figures 3 and 4 can be seen at a glance different from the reservoir and check valve structure shown in Figures 1 and 2.

More specifically

The reservoir 40 according to the present invention is formed in a cylindrical shape and the cap 20 is fastened to the opening of the reservoir 40 to seal the reservoir 40.

Thus, a thread is formed on the outer circumferential surface of the opening of the reservoir 40, and a corresponding thread is formed on the inner circumferential surface of the cap 20, so that the reservoir and the cap are fastened.

Next, a check valve is provided inside the reservoir.

The check valve 60,

It is provided on the inner circumferential surface of the reservoir, the frame 63 is formed with a circulation hole 631 for introducing the circulation water, and a valve body 65 mounted to the frame to open and close the circulation hole.

And the valve body 65,

A fastening shaft 651 for fastening with the frame and a valve membrane 653 that are connected to the fastening shaft and closed and opened the circulation hole 631 by the pressure of the circulating water.

Therefore, it is preferable that a stepped portion 41 is formed to protrude inward from a portion of the inner circumferential surface of the reservoir as shown in the drawing. The frame 63 of the check valve is fastened and fixed to the step 41.

Accordingly, the circulating water is introduced from the upper to the lower side, so that the smooth inflow of the circulating water can be expected as compared to the structure of the existing hot water supply device.

That is, the conventional hot water supply device has a structure in which the valve membrane is moved back and forth because the check valve is mounted in the longitudinal direction, and the valve membrane does not move back and forth in spite of the pressure of the circulating water. It often occurred.

However, in the present invention, the valve membrane of the check valve can be moved up and down to fundamentally solve the above problem.

According to this, the circulating water passes through the check valve from the upward direction to the downward direction in the gravity direction, so that the effect of braking on the valve membrane of the check valve can be almost eliminated (see enlarged view of FIG. 3).

Next, the present invention is characterized in that the filter portion 70 is further provided with a plurality of through-holes (70a) to the upper check valve in the reservoir.

In the process of circulating the circulating water, etc., impurities, ie, debris, may be mixed into the circulating water and introduced into the reservoir. If this filtration is not filtered, a smooth circulation of the circulating water is applied after a certain time of operation.

Therefore, in the present invention, the user can easily install the filter part 70, and the filter part is provided on the upper part of the check valve in the reservoir where the filter part by the filter part can be replaced and the filter part filtered by the filter part can be maximized. Done.

And the filter portion 70 is inserted into the check valve, that is, the upper portion of the frame as shown in the drawing as the overall shape is reduced in cross section as the downward shape becomes larger (so-called, the upper cup and the lower cup is connected It consists entirely of an hourglass shape.

That is, by applying dynamics (that is, changing the cross-sectional area) to the shape of the filter part itself, in addition to the filtering effect through the through-hole, the noise wavelength generated during the flow of the circulating water into the reservoir and moving to the check valve prevents noise. You can also get together.

In addition, as shown in the cross-sectional view of FIG. 3, the filter part 70 is blocked in the middle portion of the hourglass shape, that is, the portion where the upper cup and the lower cup are connected to each other, unlike the side surface thereof. It can be seen that the structure.

This is because when the trouble occurs in the check valve located below the circulating water is not discharged to the discharge path (O), but may rise above the check valve in the opposite direction, that is, the upper part of the manure.

That is, when a trouble occurs in the check valve and the valve is opened, the water is raised and raised in the check valve by water pressure. In the present invention, in order to prevent such a congestion phenomenon, the upper cup and the lower cup are connected to the site. It is designed to be blocked structure without drilling holes.

Furthermore, the upper end of the filter part is provided with a packing (P) to be in close contact with the cap 20 is fastened to preferably close the inside of the reservoir tank tightly.

Of course, the packing may be provided at the bottom as well as the top of the manure as shown in the figure.

In addition, the filter portion may be formed in the cross-beam shape or the light-receiving narrow cross-sectional shape is not an hourglass shape.

That is, the filter part can expect a low noise hot water circulation device by expecting the noise wavelength dispersion of the circulating water passing through the filter net by changing the cross section as well as the pure filter function.

Next, the structure in which the check valve is installed in the transverse direction in the reservoir for smooth inflow of the circulating water into the check valve, and the valve membrane of the check valve is operated up and down according to the structure in which the circulating water is introduced.

Nevertheless, the check valve is not operated so that the circulating water may not be filled in the reservoir (hereinafter referred to as "check valve") located below the check valve. Consider mounting the circulation water conductor 80 in the frame (see Figure 6).

That is, the circulating water conductor 80 has a structure of opening and closing the inlet hole 637 formed in the frame according to the amount of circulating water filled in the check valve, thereby replenishing the circulating water into the check valve.

Opening and closing portion 81 for opening and closing the inlet hole 637, and the portion connected to the opening and closing portion in the circulating water (82).

When the circulating water is normally filled in the check valve as shown in A and B of FIG. 6, the beret portion 82 is raised to the upper portion so that the opening and closing portion 81 is closed to the inlet hole.

When the circulating water is not filled into the check valve, the beret portion 82 is moved downward according to the circulating water level so that the opening and closing portion 81 opens the inlet hole 637 so that the circulating water is automatically filled. do.

Of course, the specific structure of the circulating water conductor is only one example, and the circulating water is opened by opening and closing the inlet hole into which the circulating water is input by changing the height of water by using buoyancy, such as the C and D shapes of FIG. 6. It is sufficient if the configuration is intended to flow in.

Next, as shown in the drawing, the check valve may further include a reverse circulation valve 90.

The reverse circulating valve is a check valve by forcibly discharging the circulating water in the check valve to the reservoir when the water pressure in the check valve increases by a certain amount due to the circulating water flowing into the check valve from the reservoir or the circulating pipe and flowing back into the check valve. By preventing the water pressure in the internal pressure and the water pressure in the circulation pipe from rising above a certain level, a problem such as rupture of the purified pipe is prevented from occurring. Such a reverse circulation valve is a configuration disclosed in the above-described prior art Patent No. 10-0969815 and omitted for a specific operation relationship or structure.

Next, the structure of the valve body 65 employed in the present invention will be described.

The valve body 65 is mounted to the frame to be configured to open and close the circulation hole 631,

It consists of a fastening shaft 651 having a locking portion 655 for fastening with the frame, and a valve membrane 653 connected to the fastening shaft.

In particular, the valve membrane 653 is opened by the hydraulic pressure of the circulating water to open the circulation hole 631. Preferably, the valve membrane is formed with a weakened portion 657 for inducing a smooth opening and closing of the valve membrane.

That is, the weak part 657 is configured to allow the valve membrane to be easily folded or returned to its original state by actively responding to water load.

As shown in FIGS. 3 and 4, and FIG. 5A, a weak portion 657 may be formed by forming a predetermined portion of the valve membrane in a shape in which the valve membrane is thin and protrudes backward.

In addition, the valve body may be variously modified, and may also consider the form shown in [B] of FIG.

In the case of the above-described valve body 65 disclosed in [A] of FIG. 5, if the fastening shaft 651 is formed at the central portion of the valve membrane 653, the fastening shaft 651 as shown in [B] of FIG. 5. ) May be formed at both edge portions of the valve membrane to be mounted on the frame 63.

Of course, in this case as well, the valve membrane 653 preferably has a weakened portion 657 in the valve membrane for smooth operation, and the valve membrane also forms a weakened portion at a portion connected to the fastening shaft to reach around the fastening shaft side. The valve membrane can be operated smoothly in response to the load of the circulating water.

In the above description of the present invention, a "hot water supply device" having a specific shape and structure has been described with reference to the accompanying drawings, but the present invention has been modified and modified by those skilled in the art without departing from the scope of the following claims. It is to be understood that such modifications and variations are intended to be included within the protection scope of the present invention.
