Description

Technical Field [0001] The present invention relates to a hot water supply apparatus having a compact type fastening structure,

The present invention relates to a hot water supply device having a compact type fastening structure, and more particularly, to a hot water supply device having a compact type fastening structure in which a check valve is coupled from the upper part to the lower part inside the water tank, ≪ / RTI >

Generally, a hot water mat is used for heating or maintaining the hot water by using hot water. Hot water pipes, in which hot water flows in the mat, are arranged at regular intervals. Hot water supplied from the hot water supply device is supplied to the hot water pipe, So that the mat is locally heated or kept at a constant temperature. Since the hot water mat does not use the heating wire provided on the electric mat, there is an advantage that electric safety accidents such as fire and electric shock accident are remarkably reduced without generating electromagnetic waves.

Such a hot water mat has a basic configuration of a hot water supply device, a hot water pipe and a hot water mat. The conventional hot water supply device used in the hot water mat uses a motor pump to circulate hot water. However, when the motor pump is driven, the noise and vibration of the motor itself are diverted to the outside, causing unpleasant noise, which hinders quiet and comfortable sleeping. Accordingly, in recent years, in a state in which water supplied in the heater is prevented from flowing back to the water tank without using a motor pump, hot water is supplied to the hot water pipe provided in the hot water mat by the expansion pressure generated by heating, A hot water supply device is developed.

FIG. 1 is a view for explaining a conventional hot water supply apparatus, and FIG. 2 is a view for explaining a conventional check valve.

1 and 2, a conventional hot water supply device 31 is provided to supply heated hot water to a pipe of a hot water mat 30, and a water tank 32 and a heater unit 33 And a check valve 1 is provided in the water tank 32. [ The hot water introduced into the pipe of the hot water mat (30) is supplied to the water tank (32) through the inflow pipe (35) and circulated.

The check valve 1 includes a main body 2 having an inflow portion 2a and an outflow portion 2b, a shutoff plate 3 for intermittently blocking the inflow portion 2a inside the main body 2, And a bubble discharging portion 4 for discharging the bubbles inside the main body 2.

The blocking plate 3 supplies water or circulated hot water in the direction of the supply pipe 34 connected to the heater unit 33 so that the hot water does not flow backward. That is, when the water supplied to the heater unit 33 is heated to the preset temperature, the blocking plate 3 blocks the inflow portion 2a inside the main body 2 by the inflation pressure of the heated water, So that the hot water does not flow backward and hot water is supplied to the piping of the hot water mat 30. Then, the water whose temperature is circulated while circulating in the hot water mat (30) is supplied to the water tank (32) through the inflow pipe (35). When the hot water is supplied to the hot water mat 30 from the heater unit 33, the pressure inside the heater unit 33 is lowered while the pressure in the water tank 32 becomes higher, At this time, the water in the water tank 32 flows into the main body 2 through the inflow portion 2a.

The bubble discharging portion 4 discharges bubbles collected in the main body 2 and includes an opening and closing portion 4c for opening and closing the through portion 2c formed in the upper portion of the main body 2 to discharge the bubbles, A fixing part 4a for fixing one side of the main body 2 to the upper part of the main body 2 and a buoyancy part 4b mounted on the lower side of the opening part 4b. However, in the case of the opening / closing part 4c, it often comes into close contact with the penetrating part 2c due to the cohesive force of water or the like. In this case, the opening / closing part 4c closes the penetrating part 2c, so that the bubbles collected in the main body 2 can not be discharged to the outside and are accumulated in the main body 2, do. When the shutoff plate 3 of the check valve 1 opens the inlet 2a so that the water in the water tank 32 must flow into the main body 2 through the inlet 2a, There is a problem that the inflow portion 2a can not be opened due to the high pressure inside the inflow portion 2.

In order to solve this problem, the present applicant has devised a hot water supply device capable of easily discharging bubbles, as disclosed in Registration Utility Model No. 20-0469269.

3 is a view for explaining a hot water supply device in which conventional bubbles are easily discharged.

3, the conventional hot water supply device 50 has a water tank 60 provided with an inlet 62 and a discharge port 64, and a water tank 60 provided inside the discharge port 64 of the water tank 60 And a heater unit (not shown) provided outside the discharge port 64 of the water tank 60. [ The check valve 70 includes a main body 72 having an inlet 72a and an outlet 72b, a disk 75 mounted on the inside of the main body 72, The bubble discharging part 80 and the bubble discharging part 80 for discharging the bubbles provided inside the main body 72 by opening and closing the discharge port 72c of the main body 72, And a discharge portion 90 for opening and closing the hole 72d. The lower surface of the disk 75 facing the inlet 72a of the main body 72 is fixed to the lower portion of the inlet 72a and the upper surface of the disk 75 is connected to the water tank 60 and the main body 72 To close or close the inlet 72a of the main body 72 while being in close contact with or spaced from the inner wall of the main body 72. [ When the water supplied to the heater unit is heated, bubbles are generated in the process of heating the water. The bubbles are introduced into the main body 72, and then are discharged into the main body 72 by the bubble discharge unit 80 and the discharge unit 90, (72).

On the other hand, when water is supplied to the water tank 60 through the opening of the water tank 60 in a state where water supply into the main body 72 has not yet been completed, The upper side of the disk 75 blocking the inlet 72a of the main body 72 should be moved away from the main body 72 in order to be introduced into the main body 72. [

However, in order for the upper surface of the disc 75 to be separated from the main body 72, a pressure greater than the elastic force of the disc 75 itself blocking the inflow portion 72a of the main body 72 must be applied to the disc 75 The upper side of the disk 75 cuts off the inflow portion 72a of the main body 72 until the water supplied to the water tank 60 becomes a certain volume or more, The hot water can not be quickly supplied to the piping of the hot water mat.

When the upper side of the disk 75 is spaced apart from the main body 72 while the upper side of the disk 75 is in close contact with the inner wall provided with the inlet portion 72a of the main body 72, May be closely adhered to the inner wall of the main body 72 due to cohesive force of water or the like. In this case, even if a pressure larger than the elastic force of the disc 75 itself blocking the inlet portion 72a of the main body 72 is applied to the disc 75, the upper side of the disc 75 is covered with the main body 72 There is a fear that the product is not separated and recognized as a product malfunction, which leads to a problem that the reliability of the product is lost.

The main body 72 of the check valve 70 mounted inside the water tank 60 is provided with an inlet portion 72a at the side thereof so that the water of the water tank 60 flows into the inlet portion 72a of the main body 72, An extra space is required outside the inlet 72a of the body 72 in order to allow easy entry into the body 72a which increases the overall size of the water tank 60, Is increased.

In order to mount the main body 72 of the check valve 70 inside the water tank 60, first, the main body 72 is positioned inside the water tank 60, and then, from the outside of the water tank 60 It is necessary to fix the main body 72 to the water tank 60 by using bolts or the like. For this purpose, the worker has to work while alternating between the inside and the outside of the water tank 60, There is a problem that is not easy.

When the blocking unit 220 contacts the inlet 214b of the cover 210, One surface of the blocking portion 220 facing the slope surface 214a of the cover portion 210 strikes the slope surface 214a of the cover portion 210 so that a sound is generated. The impact sound is a noise that makes the user feel uncomfortable. Therefore, a shock buffer (not shown) formed of a cushioning member such as synthetic resin, silicone, rubber or the like which is easy to absorb impact energy is formed on one surface of the blocking portion 220 facing the inclined surface 214a 230 so that the noise generated when one surface of the blocking portion 220 hits the inclined surface 214a of the cover portion 210 is remarkably reduced. A coupling hole 232 is formed at the center of the shock buffer 230 so that the shock buffer 230 can be easily coupled to one surface of the shield 220. The shield 230 is formed on one surface of the shield 220, The fitting portion 224 is formed so as to be inserted into and engaged with the fitting hole 232. In addition, the shock buffer 230 may be omitted in some cases.

When the internal pressure of the second accommodating portion 120 rises abnormally due to water or bubbles flowing into the second accommodating portion 120 of the water tank 100, Will be described with reference to the following drawings.

Hereinafter, the operation of the hot water supply apparatus having a compact type fastening structure according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

8 is a perspective view illustrating a state in which the water in the water tank is introduced into the heater unit in a state where there is no water in the second storage unit of the water tank of the hot water supply apparatus having the compact type fastening structure according to the preferred embodiment of the present invention FIG.

8, when the user supplies water to the first receiving portion 110 of the water tank 100 in order to use the hot water mat, the water in the first receiving portion 110 is guided by the guide of the cover portion 210 And is supplied to the second accommodating portion 120 through the hole 212a and the inflow portion 214b. At this time, since the blocking part 220 mounted on the inclined surface 214a of the cover part 210 is inclined, gravity is applied to the blocking part 220 by the self weight of the blocking part 220, Is spaced apart from the inclined surface 214a of the cover portion 210. The pressure of the lower portion of the cover portion 210 is lower than that of the cover portion 210. [ As a result, the upper portion of the blocking portion 220 is moved downward while being separated from the inclined surface 214a of the cover portion 210 to open the inflow portion 214b of the cover portion 210, The water in the first accommodating portion 110 flows into the second accommodating portion 120 of the water tank 100 through the opened inflow portion 214b of the cover portion 210. [ The water flowing into the second storage portion 120 flows into the heater portion 300 through the discharge portion 122 formed in the second storage portion 120.

Since the blocking portion 220 is positioned so as to be inclined along the inclined surface 214a of the cover portion 210, the blocking portion 220 can prevent the blocking portion 220 from flowing into the inlet portion of the cover portion 210, So that the water in the water tank 100 can be rapidly introduced into the heater unit 300.

FIG. 9 is a view for explaining a state in which water flows into the second accommodating portion of the water tank of the hot water supply apparatus having the compact type fastening structure according to the preferred embodiment of the present invention, so that the inflow portion of the cover portion is closed.

9, the water contained in the first receiving portion 110 of the water tank 100 flows into the second receiving portion 120 of the water tank 100 through the open inlet 214b of the cover portion 210 The blocking portion 220 floats due to its own buoyancy. At this time, the buoyancy force is greater than the gravity force applied to the shutoff part 220, and as the water enters the second accommodation part 120 of the water tank 100, The cover 220 is moved in the direction of the inclined surface 214a of the cover portion 210 so that the inflow portion 214b formed in the inclined surface 214a is closed.

The water flowing into the second storage portion 120 of the water tank 100 flows into the heater portion 300 through the discharge portion 122 formed in the second storage portion 120. At this time, the water flowing into the heater unit 300 is heated and steam is generated, so that the pressure inside the heater unit 300 increases. When the internal pressure of the heater unit 300 increases, the heater unit 300 300 are pushed in the direction of the hot water pipe 320 provided at the other side of the heater unit 300. One side of the heater unit 300 is blocked by the shutoff unit 220 of the check valve 200 so that the water of the heater unit 300 does not flow back toward the water tank 100.

Fig. 10 is a view showing a state in which water in the first storage portion of the water tank is supplied to the second storage portion in a state where water is present in the second storage portion of the water tank of the hot water supply apparatus having the compact type fastening structure according to the preferred embodiment of the present invention Fig.

10, the water supplied from the water tank 100 to the heater unit 300 is heated to a preset temperature, the heated water is supplied to the hot water mat and circulated, and the water in the water tank 100 is heated by the heater (300). At this time, a space corresponding to the volume of water supplied to the heater unit 300 is formed in the second accommodating unit 120 of the water tank 100, and the water level of the water in the second accommodating unit 120 of the water tank 100 It will be as low as that. The upper portion of the blocking portion 220 is moved downward while being separated from the inclined surface 214a of the cover portion 210 so that the inflow portion 214b of the cover portion 210 Is opened. The water in the water tank 100 flows into the second accommodating portion 120 of the water tank 100 again through the open inlet 214b of the cover portion 210.

11 is a view illustrating a process of moving a fluid while a check valve of a hot water supply apparatus having a compact type fastening structure according to a preferred embodiment of the present invention is opened and closed.

Referring to FIG. 11, the water tank 100 and the heater unit 300 are accommodated in a housing (not shown). A mat portion (330) is provided on the outer side of the housing, and a hot water pipe (320) is embedded in the mat portion (330). The discharge unit 122 and the heater unit 300 provided in the second storage unit 120 of the water tank 100 are connected to each other by the first connection pipe 310 and the hot water pipe 320, The supply part 112 provided in the first receiving part 110 of the main body 100 is connected to each other by the second connection pipe 340. The water supplied from the outside to the first receiving portion 110 of the water tank 100 and the water supplied to the first receiving portion 110 of the water tank 100 is guided through the guide holes 212a And then flows into the second accommodating portion 120 through the inflow portion 214b and is discharged to the heater portion 300 through the discharge portion 122 of the second accommodating portion 120. [ At this time, as the water in the second accommodating portion 120 of the water tank 100 is filled with water, the blocking portion 220 floats so that the blocking portion 220 contacts the inclined surface 214a of the cover portion 210, The inlet 214b of the portion 210 is closed. Thereafter, when the temperature of the water supplied to the heater unit 300 is heated to a predetermined temperature, the internal pressure of the heater unit 300 increases, and the heated water flows into the hot water pipe 320 connected to the other side of the heater unit 300, And is then moved to the first receiving portion 110 of the water tank 100 through the second connecting pipe 340. [ When the heated water in the heater unit 300 is discharged to the hot water pipe 320, a space as much as the discharged water is generated so that the blocking unit 220 is separated from the inclined surface 214a of the cover unit 210, The water in the water tank 100 flows into the second accommodating portion 120 of the water tank 100 through the inlet portion 214b of the cover portion 210 and then flows into the second accommodating portion 120 of the water tank 100, And then flows into the heater unit 300 through the heater unit 122, and the circulation process is repeated.

The bubbles generated in the process of heating the water supplied to the heater unit 300 flow into the second accommodating unit 120 through the discharge unit 122 of the second accommodating unit 120. Then, the pressure of the second accommodating portion 120 is increased by the air bubbles of the second accommodating portion 120. At this time, the air bubbles flowing into the second accommodating portion 120 penetrate the space between the upper portion of the blocking portion 220 and the inclined surface 214a of the cover portion 210 due to the pressure. The upper part of the blocking part 220 is spaced apart from the inclined surface 214a of the cover part 210 so that the inflow part 214b of the cover part 210 is opened and the bubble is inflow of the opened cover part 210 So that the internal pressure of the second accommodating portion 120 is returned to a normal level.

The water tank 100 is divided into a first storage portion 110 in which water is received and a second storage portion 120 provided in the lower portion of the first storage portion 110, The water accommodated in the first accommodating portion 110 of the water tank 100 is guided to the guide hole 212a formed in the lid portion 212 of the check valve 200 by gravity, So that a separate space for moving the water in the first storage part 110 of the water tank 100 to the second storage part 120 is required It is possible to obtain an overall compact appearance. Since the check valve 200 is assembled in the water tank 100 as a whole, the check valve 200 is moved alternately between the outside and the inside of the water tank 100 in order to couple the check valve 200 to the water tank 100 There is an effect that the assembling time is remarkably shortened and the assembling is facilitated.

12 is a view for explaining a discharge member provided in a check valve of a hot water supply apparatus having a compact type fastening structure according to a preferred embodiment of the present invention.

12, the air bubbles flowing into the second accommodating portion 120 of the water tank 100 pierce a space between the blocking portion 220 and the inclined surface 214a of the cover portion 210 The inlet portion 214b of the cover portion 210 is opened and then discharged to the first receiving portion 110 of the water tank 100 through the opened inlet portion 214b. When the blocking portion 220 is in close contact with the inclined surface 214a of the cover portion 210 due to the cohesive force of water and the inflow portion 214b of the cover portion 210 is not opened, It is inevitably increased abnormally. In this case, the cover member 210 is further provided with a discharge member 240 including a discharge cap 242 and a cover cap 244.

The discharge cap 242 covers the guide hole 212a formed in the cover part 212 of the cover part 210 and is concave at the upper part and the lower part of the guide hole 212a of the cover part 210, And is connected to the inner periphery of. A through hole 242a is formed in the side of the discharge cap 242 so that bubbles discharged from the guide hole 212a are discharged to the outside.

The cover cap 244 is made of a synthetic resin material such as rubber excellent in adhesion and elasticity and is formed so as to cover the outside of the discharge cap 242 so that its inner periphery closes the through hole 242a of the discharge cap 242 . And a cover hole 244a is formed so that the upper portion of the cover cap 244 is opened.

The bubble introduced into the second accommodating portion 120 is moved in the direction of the through hole 242a of the discharge cap 242 by the rising pressure of the bubble itself to apply pressure to the cover cap 244. Then, the cover cap 244 instantaneously stretches and spreads outward. At this time, the cover cap 244 is spaced apart from the through-hole 242a of the discharge cap 242 so that the through-hole 242a is opened so that the bubble can pass through the opening 242a of the discharge cap 242, And is easily discharged to the first accommodating portion 110 through the cover hole 244a of the first accommodating portion 244. The bubble introduced into the second accommodating portion 120 can be easily discharged to the outside through the discharge member 240 even if the blocking portion 220 blocks the inflow portion 214b of the cover portion 210. [ .

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined in the appended claims. If it belongs to the category of utility model registration claim, the technical idea should also be regarded as belonging to this invention.
