Generally, electric mats and electric mats used in the winter season are used in public because the floor of the room is heated locally or can show the effect of heating in a short time.

However, there is a risk of electric shock due to the use of electric wires installed in electric plates or electric mats, and it is widely known that harmful electromagnetic waves are generated due to their electric characteristics and the electromagnetic waves are harmful to human body.

Recently, a hot water mat adopting the traditional ondol method using hot water of high temperature is sold on the market in accordance with the characteristic of Korea which is familiar with the ondol culture.

Generally, the hot water mat has a circular tube uniformly arranged therein.

Such a hot water mat includes a liquid temperature controller such as a boiler, and the hot water heated in the liquid temperature controller is heated while moving in the circulation pipe.

Generally, a liquid temperature controller for a hot water mat is equipped with a heater, a housing, a check valve, and the like in order to heat circulating water, i.e., liquid.

Wherein the check valve is configured to open and close a through hole through which the liquid is supplied to the inside of the housing to supply a predetermined amount of the liquid to be supplied to the heater through the housing while simultaneously discharging the liquid heated and inflated by the heater to the through hole To the circulation pipe without being discharged to the outside of the housing.

Therefore, it is possible to circulate the liquid to the mat through the circulation pipe without the circulation pump by the check valve.

Such a conventional check valve generally opens and closes the through-hole by the expansion pressure generated when the liquid is heated.

Accordingly, even if the amount of the liquid supplied to the inside of the housing is small, there is a problem that the liquid can not be further supplied to the inside of the housing if the inflation pressure is high.

FIG. 6 is a cross-sectional view of the state in which the check valve is raised and the through-hole is closed in FIG. 5; FIG. 6 is a sectional view showing a state where liquid is introduced into the housing through a check valve assembly for a hot water mat;

1 to 6, a check valve assembly 100 for a hot water mat according to the present invention includes a housing 110, a cover 120, a check valve 130, a position fixing part 140 .

The housing 110 has a communication hole 113 through which liquid such as water is received, an upper portion is opened, and a liquid hole 113 is formed in a lower side of the housing 110 to discharge the liquid contained therein.

In the interior of the housing 110, a first accommodating portion 111 and a second accommodating portion 112, in which the liquid is received, are arranged so as to communicate with each other.

The communication hole 113 is formed on a side of the first accommodating part 111 located below and connected to a heater 210 coupled to the outside of the housing 110.

Therefore, the liquid that has moved from the inside of the first accommodating portion 111 to the heater 210 through the communication hole 113 is heated by the heater 210.

Since the conventional heater 210 for a hot water mat is sufficient, detailed description thereof will be omitted.

The cover 120 covers an upper portion of the first accommodating portion 111 formed at a lower portion of the housing 110.

Accordingly, the first receiving portion 111 and the second receiving portion 112 are divided by the cover 120. [

The cover 120 is formed with a through hole 121 through which the liquid accommodated in the second accommodating portion 112 disposed at the upper portion is moved to the first accommodating portion 111 disposed at the lower portion have.

In other words, the liquid located on the upper portion of the cover 120 is received in the lower portion of the cover 120, that is, the first accommodating portion 111 through the through hole 121.

The check valve 130 is disposed in the first accommodating portion 111 to close the through hole 121 when it ascends and to open the through hole 121 when the check valve 130 is lowered.

Although one check valve 130 is shown in the drawing of this embodiment, a plurality of check valves 130 may be provided as necessary.

In the present invention, the check valve 130 is lifted and lowered by buoyancy acting from the liquid contained in the first accommodating portion 111 to open / close the through hole 121.

That is, the check valve 130 is kept floating in the liquid contained in the first accommodating part 111, and is lifted and lowered according to the height of the liquid to open / close the through-hole 121.

The check valve 130 includes a support 131, an opening / closing part 132, and a floating part 133.

The support base 131 is disposed under the cover 120.

The opening / closing part 132 extends horizontally on the outer circumferential surface of the support base 131 and is disposed below the through hole 121.

When the check valve 130 rises, the upper surface of the opening / closing part 132 contacts the lower surface of the cover 120 to close the through hole 121. When the check valve 130 descends, The through hole 121 is separated from the lower surface of the through hole 121.

At this time, the diameter of the opening / closing part 132 is formed to be larger than the diameter of the through hole 121, and when the check valve 130 rises, the upper surface of the opening / closing part 132 closes all the through holes 121 .

In this embodiment, the opening / closing part 132 is composed of the extended supporting part 134 and the close contact member 135.

The extended support part 134 is integrally formed with the support part 131 and extended in the horizontal direction in the support part 131.

The contact member 135 is made of an elastic material such as silicone or rubber and is coupled to the upper surface of the extended support portion 134.

The contact member 135 is pressed against the lower surface of the cover 120 when the check valve 130 is lifted, so that the through-hole 121 can be more closely closed.

In this embodiment, the tight contact member 135 is engaged with the support base 131, but may be coupled to the support base 131 or the extended support portion 134 in various other directions.

The floating part 133 is disposed below the opening / closing part 132 and is made of a material such as styrofoam floating on the liquid.

A coupling groove is formed in the floating portion 133 and a lower portion of the support 131 is inserted into the coupling groove and coupled to the floating portion 133.
3, the lower portion of the support base 131 further protrudes downward from the opening / closing portion 132. The lower portion of the support base 131 protrudes from the lower portion of the opening / 133, respectively.

Accordingly, when the floating portion 133 is lifted due to the buoyancy acting on the liquid, the upper surface of the opening / closing portion 132 contacts the lower surface of the cover 120 to close the through hole 121.

That is, the check valve 130 on which the floating portion 133 is mounted is raised and lowered according to the height of the liquid contained in the first accommodating portion 111, The through hole 121 can be closed so that a predetermined amount of liquid can always be received in the first receiving portion 111. [

A closed projection 124 is formed on the lower surface of the cover 120 along the circumference of the through hole 121.

The lower surface of the sealing projection 124 contacts the upper surface of the opening / closing part 132 when the check valve 130 rises, thereby closing the through hole 121 more effectively.

The position fixing portion 140 is formed on a bottom surface of the housing 110 where the first accommodating portion 111 is formed and / or a bottom surface of the cover 120, Thereby preventing it from flowing.

The position fixing unit 140 includes a first position fixing protrusion 141 protruding upward from a bottom surface of the housing 110 where the first housing unit 111 is formed, And a second position fixing protrusion 142 protruding downward from the lower surface of the first fixing protrusion 120.

A position fixing groove 137 into which the first position fixing protrusion 141 is inserted is formed on a lower surface of the check valve 130.

The second position fixing protrusion 142 is disposed adjacent to the outer peripheral surface of the check valve 130 while surrounding the outer circumferential surface of the check valve 130.

This prevents the check valve 130 from being moved to another position by the first position fixing protrusion 141 and the second position fixing protrusion 142 when the check valve 130 is lifted or lowered.

The first position fixing protrusion 141 may be formed to surround the outer circumferential surface of the lower portion of the check valve 130 like the second position fixing protrusion 142 and the first position fixing protrusion 141 And the second position fixing protrusion 142 may be formed.

FIG. 4 shows a state in which the check valve assembly 100 of the present invention is mounted on the hot water mat 240.

The hot water mat 240 of the present invention includes a liquid temperature controller 220, a circulation pipe 230, and a mat 240, as shown in FIG.

The liquid temperature controller 220 is installed inside the check valve assembly 100 described above.

The other structure of the liquid temperature controller 220 except for the check valve assembly 100 of the present invention is the same as that of the known temperature controller of the hot water mat, and a detailed description thereof will be omitted.

Most of the circulation pipe 230 is disposed inside the mat 240. Both ends of the circulation pipe 230 are connected to the liquid temperature controller 220 and supplied through the check valve assembly 100 to the heater 210 Circulates the heated liquid in the mat 240 to the mat 240.

The mat 240 is a place where users sit on the upper part, and the circulation pipe 230 is disposed therein.

Accordingly, when the liquid heated in the liquid temperature controller 220 is circulated through the circulation pipe 230, the mat 240 is heated by the heated liquid.

Hereinafter, an operation process of the present invention having the above-described configuration will be described.

5, the check valve 130 is lowered to open the through hole 121, so that the first receiving portion 111 111 and the second accommodating portion 112 are maintained in a mutually communicated state through the through hole 121.

The check valve 130 may include the first position fixing protrusion 141 inserted into the position fixing groove 137 and the first position fixing protrusion 141 disposed adjacent to the outer circumferential surface of the check valve 130 So as to maintain its position without being horizontally moved.

In this state, when the liquid is poured into the second accommodating portion 112, the liquid is received in the first accommodating portion 111 through the through hole 121, And floats on the liquid surface of the liquid by the capillary 133.

As the height of the liquid is received in the first accommodating portion 111, the check valve 130 floating in the liquid due to the buoyancy acting on the liquid gradually rises, and as shown in FIG. 6 The opening and closing part 132 closes the lower part of the through hole 121. [

The liquid contained in the first accommodating portion 111 is moved to the heater 210 through the communication hole 113 and heated.

As the liquid is heated by the heater 210, the liquid expands and generates a pressure. Due to the expansion pressure or the like, the check valve 130 tries to rise further, So that the opening and closing part 132 can close the through hole 121 more securely.

The liquid contained in the first accommodating portion 111 is heated by the heater 210 in a state where the through hole 121 is closed by the check valve 130 as described above, When the pressure reaches a certain level, the liquid contained in the heater 210 and the first accommodating portion 111 flows through the circulation pipe 230 due to the inflation pressure.

When the liquid in the first storage part 111 moves to the circulation pipe 230, the water level of the first storage part 111 is lowered so that the check valve 130 is lowered again, The liquid contained in the fraudulent second receiving portion 112 is again received in the first receiving portion 111 through the through hole 121. [
