The water receiving unit 120 is a water tank for storing the water to be supplied to the hot water mat. As shown in FIG. 2, the water receiving unit 120 is disposed inside the housing 110 to store a predetermined amount of water injected therein, The partition wall 123 is partitioned into an upper water tank 121 and a lower water tank 122 by a partition wall 123. The partition wall 123 is formed with an inflow hole 124 opened upward and downward. Here, a control hole 126 (see FIG. 4A) may be formed at one side of the partition 123 to open and close the pressure regulator 160.

As shown in FIGS. 2 and 3, one end of the pipe member 130 is connected to a circulation pipe of the hot water mat, and the pipe member 130 is connected to the lower water tank 122 And the other end communicates with the water supply port 111 so as to be connected between the lower water tank 122 and the water supply port 111.

Here, the water supply pipe 131 has a relatively larger inner diameter than the water supply port 111, and a connection pipe 133 connected to the water supply port 111 is installed at the end of the water supply pipe 131 so that the diameter gradually decreases. . The supply pressure of the water supplied to the hot water mat can be greatly increased through the connection pipe 133 and the pressure of the reverse flow when the water supplied from the circulation pipe reversely flows can be buffered while reducing the pressure.

The heater 140 may be provided to heat the water stored in the lower water tank 122 to heat the water supplied to the water supply pipe 131. However, And may be arranged to extend around the water supply pipe 131 to heat the water to be fed toward the water supply port 111 by driving the water in accordance with a control signal from the control circuit unit 190.

Therefore, compared with the case where the heater is disposed inside the water receiving unit 120, it is possible to reduce the space occupied by the heater in the water receiving unit 120, thereby making it possible to miniaturize the product, It is possible to prevent the thermal efficiency from dropping while the water having low temperature is mixed in the water tank.

The valve body 150 is a flow rate adjusting member that is opened and closed to supply water stored in the upper water tank 121 to the lower water tank 122 disposed below the valve body 150. The valve body 150 is disposed below the inflow hole 124, And moves up and down according to a change in the internal pressure of the inlet 122 to open and close the inlet hole 124.

2 and 4A, a guide bar 127 protruding upward from the bottom surface of the lower water tank 122 by a predetermined length is formed, A hollow 153 inserted into the bar 127 is formed at an upper portion and a lower portion at the center and is formed of a buoyancy material and floated by the water supplied to the lower water tank 122 and selectively covers the lower portion of the inflow hole 124 And a packing portion 152 which is annularly disposed on the upper surface of the buoyant body 151 to seal the lower circumference of the inflow hole 124 in a watertight manner in accordance with the rise of the buoyant body 151 ).

The pressure regulating unit 160 is a pressure regulating unit that automatically opens when the pressure in the conduit rises rapidly as the circulation conduit is bent or pressed and pressurized to reduce the internal pressure to a normal value. When the inner pressure of the lower water tank 122 reaches a predetermined high pressure value, the valve is opened and the pressure of the lower water tank 122 is discharged to the upper water tank 121, thereby reducing the internal pressure .

4A, when the pressure regulating unit 160 is disposed on the partition wall 123, the pressure regulating unit 160 includes a support plate (not shown) disposed on the upper water tank 121, An extension portion 163 extending downward from the lower surface of the support plate 162 and penetratingly inserted into the adjustment hole 126 at a lower end thereof and having a predetermined elastic repulsion force, And an elastic member 164 which is supported between the lower periphery of the supporting plate 162 and the engaging jaw and presses the supporting plate 162 downward.

A support plate 166 supported on the upper surface of the upper portion of the control hole 154 opened upward and downward at the center of the valve body 150 when the valve body 150 is disposed; An extension portion 167 extending downward from the lower surface of the control hole 154 so as to be inserted into the control hole 154 and having an engagement protrusion at a lower end thereof, And an elastic member 168 supported to support the support plate 166 downward.

Here, the high pressure value means a pressure value corresponding to an internal pressure which is raised when the circulation duct is bent or pressed. Therefore, it is preferable that the elastic repulsive force of the elastic members 164 and 168 is determined within a range where the elastic repulsive force of the elastic members 164 and 168 is operated under a normal internal pressure, and the pressure regulating unit 160 can be opened while being compressed at the abnormal pressure value.

Next, the operation principle of the hot water supply device 100 according to the preferred embodiment of the present invention will be described with reference to FIGS. 4A and 4B.

First, when water is injected into the upper water tank 121 through the inlet 115, the water injected into the lower water tank 122 is supplied through the inlet hole 124, The float body 151 is lifted by the buoyancy to close the lower portion of the inflow hole 124 to cut off the water supply.

The control circuit 190 controls the heater 140 so that the heater 140 is heated to the set temperature according to the operation signal of the operation unit 113. When the water in the water supply pipe 131 is heated and the water stored in the lower water tank 122 is heated, A larger buoyancy force acts on the buoyant body 151 as the internal pressure of the lower water tank 122 increases, so that the inflow hole 124 is pressurized with a stronger force and is tightly sealed.

The water temperature in the water supply pipe 131 rises and a pressure difference is generated in the circulation pipe to generate a circulating flow from the water supply port 111 to the recovery port 112. In accordance with the circulation flow, When the water stored in the water tank 122 is discharged through the water supply pipe 131 and the internal pressure of the lower water tank 122 is reduced, the buoyant force applied to the buoyant body 151 is reduced, and a part of the inlet hole 124 is opened The water stored in the upper water tank 121 flows into the lower water tank 122 through the inflow hole 124 and the hot water heated by the hot water mat is continuously supplied while repeating this process.

Meanwhile, when the circulation duct is bent or pressurized during use of the hot water mat, if the pressure in the channel suddenly rises, the increased internal pressure is transmitted to the lower water tank 122, and the internal pressure of the lower water tank 122 also increases .

When the inner pressure reaches a predetermined high pressure value of the pressure regulating portion 160 and becomes greater than the elastic repulsive force of the elastic members 164 and 168, the elastic members 164 and 168 are compressed as shown in FIG. 4B, The pressure of the lower water tank 122 is discharged to the upper water tank 121 while the adjusting holes 126 and 154 are opened and the pressure of the lower water tank 122 is lowered to a normal value It continues until.

Meanwhile, in the hot water supply apparatus 100 according to the preferred embodiment of the present invention, when an abnormally high pressure that is large enough to rupture the piping is detected, the heater 140 is stopped by emergency, Can be reduced.

A pressure sensor 180 disposed in the lower water tank 122 for detecting a change in internal pressure and transmitting a pressure sensing signal to the control circuit unit 190; And a control circuit 190 for controlling the heating operation of the heater 140.

The control circuit 190 calculates the internal pressure value of the lower water tank 122 according to the pressure sensing signal received from the pressure sensor 180. When the calculated internal pressure value reaches the pressure limit value, (140) to stop in an emergency.

Therefore, even when a high pressure abnormality occurs, which is difficult to control by the pressure regulator 160, the heater 140 is stopped to reduce the internal pressure, thereby effectively preventing the ruptured portion of the pipeline from being ruptured or leaking have.

Meanwhile, the pressure regulator 160 includes a plurality of pressure valves 161 and 165, so that the pressure can be more effectively reduced when an abnormally high pressure is generated.

2 and 4A, the pressure regulator 160 is disposed on the partition wall 123 so that the internal pressure of the lower water tank 122 reaches the first high pressure value A first pressure valve 161 for discharging the pressure of the lower water tank 122 to the upper water tank 121 when the lower pressure water is supplied to the lower water tank 122, And a second pressure valve 165 for releasing the pressure of the lower water tank 122 to the upper water tank 121 when the second high pressure value is set lower or higher than the first higher pressure value. Accordingly, the first pressure valve 161 and the second pressure valve 165 can be operated individually according to changes in the internal pressure of the lower water tank 122, thereby effectively reducing the internal pressure of the lower water tank 122.

In addition, since it is possible to discharge the minimum amount of water required for pressure control while individually opening and closing stepwise, it is possible to minimize the decrease in thermal efficiency while discharging the heated water to the outside, and the second pressure valve 165 150 to provide a condition in which the lower water tank 122 can be manufactured in a small size.

2, the hot water supply apparatus 100 according to the preferred embodiment of the present invention includes a sensing unit 120 disposed on one side of the upper water tank 121, for sensing a capacitance value that varies depending on an amount of water to be injected, And a capacitance type water level sensor 170 for outputting the water level sensor 170.

The control circuit unit 190 compares the sensed signal output from the electrostatic capacitive level sensor 170 with the pre-stored level measurement reference value to calculate a water level according to the water amount injected into the water receiving unit 120, And is output to the display unit 114. [

As described above, in sensing the water level of the water injected into the water receiving unit 120, unlike the conventional floating type water level sensing method, the electrostatic capacity value sensor 170 changes the capacitance value It is possible to detect the change of the water level with a relatively short detection distance, thereby making it possible to miniaturize the product and provide an effect of sensitively detecting a minute water level change.

In the present embodiment, the structure in which the hot water supply device 100 circulates water in a non-powered manner has been described. However, the present invention can also be applied to a hot water supply device of a forced circulation power type in which water is circulated by a motor pump, It is possible to implement an automatic pressure regulation function according to the internal pressure.

In addition, since the two lower water tanks 122 are disposed on the water receiving unit 120 and the two water pipes 131 and the return pipe 132 are connected to the water tank 120, have.

In the case where the circulation duct in the hot water mat is bent or pressed so that the pressure inside the hot water mat suddenly rises due to the respective constitutions and functions of the hot water supply device 100 according to the preferred embodiment of the present invention, The pressure regulating unit 160 disposed inside the pressure regulating unit 160 is automatically opened to reduce internal pressure or to stop the heating operation of the heater 140 to stop the supply of the water to cut off the supply of the water, Can be effectively prevented.
