Alternatively, although not shown, it is also possible that the other side of the second valve 240 (V2) is sealed with a predetermined cap Cap.

Hereinafter, it is assumed that the other side of the second valve 240 (V2) is open to the outside. Hereinafter, when the second valve 240 (V2) is turned on, it is assumed that a predetermined cover covering the other side of the second valve 240 (V2) is removed.

The second valve (240, V2) is for discharging the heated water to the outside, and may be located at the lower end of the heating water tank 200, for example, the bottom surface of the heating water tank 200 to improve the efficiency of the discharge of the heated water.

The operation of the hot water mat in this configuration in the heating mode and the drain mode will be described below.

5, in the heating period HP during which the heating mode is executed, the first and second valves 220 and V1 are turned on and the second valves 240 and V2 are turned off, (Turn-Off).

In addition, in the heating period HP, the circulation pump 210, CP may be activated and the air pump 230, AP may be inactivated. Here, the activation of the pump means that the pump is powered to drive the pump, and the deactivation of the pump may mean that the pump is not powered because the pump is not powered.

In the heating period HP, electric power is supplied to the heater 201 so that the heating water can be heated. That is, heat exchange between the heating water and the heater 201 can be performed in the heating water tank 200.

6, the circulating pump 210, CP is activated to supply the heating water of the heating water tank 200 to the heating pipe 11 of the mat 10, 1 valves 220 and V1 are turned on to supply the heating water of the heating pipe 11 to the heating water tank 200. [

Accordingly, a hot water mat driving cycle of heating-supplying-recovering can be formed.

In the drain period DP during which the drainage mode is executed, the first valve 220, V1 may be turned off and the second valve 240, V2 may be turned on.

In addition, in the drainage period DP, the circulation pump 210, CP can be inactivated and the air pump 230, AP can be activated.

In the drain period DP, the power supply to the heater 201 can be cut off.

In this drainage period DP, the circulation pumps 210 and CP are deactivated, so that the heating water supply from the heating water tank 200 to the heating pipe 11 can be cut off.

In addition, the air pump 230, AP can be activated to inject air toward the heating pipe outlet 11B. Then, the heating water can be pushed in the direction opposite to the heating mode by the air applied to the heating pipe outlet 11B. That is, the heating water is supplied to the second valve (not shown) that is turned on via the heating pipe outlet 11B, the heating pipe inlet 11A, the circulation pump 210, and the heating water tank 200, (240, V2).

The air supplied by the air pumps 230 and AP is injected mainly into the heating pipe outlet 11B of the mat 10 by turning off the first valve 220 and V1 so that the heating water discharge efficiency can be improved have.

The multiple mode can be executed according to the user's command input. For example, the drain mode can be activated when the user presses the operation command button for several seconds.

In the drain mode, since the heating water is discharged to the outside, the execution command of the drain mode needs to be set more complicated than other commands, for example, commands such as temperature control. Alternatively, it may be possible to make it difficult to select a button for inputting a drainage mode execution command in comparison with other buttons.

8, it is possible to provide the third valves 250 and V3 on the discharge side of the air pumps 230 and AP in order to prevent the heating water from moving toward the air pumps 230 and AP.

For example, the third valve 250, V3 may be disposed between the third stage EP3 of the 3-way branch pipe 300 and the air pump 230, AP.

Such third valves 250 and V3 can be turned on in the drain period DP of the drain mode while maintaining the turn-off state in the heating period HP of the heating mode, as shown in Fig. In this case, it is possible to prevent the heating water from flowing into the air pumps 230, AP in the heating period HP in which the air pumps 230, AP are not operated.

The third valves 250 and V3 are connected to a check valve Check to prevent heating water from flowing in the direction of the air pumps 230 and AP in a period during which the air pumps 230 and AP do not operate, Valve).

The check valve allows the fluid to flow in the forward direction, while the reverse flow is a type of valve that automatically closes.

The check valves that can be applied to the present invention include a wafer type check valve, a split type check valve, a swing type check valve, a lift type check valve, a mushroom type ) Check valve, disk type check valve, etc. are possible.

On the other hand, in the drain mode, it is possible to turn the first valve (220, V1) on again after a predetermined time in the state of turning off.

10, the drainage period DP in which the drainage mode is executed may include a first drainage period DP1 and a second drainage period DP2 after the first drainage period DP1, for example. have.

The first valve 220, V1 may be turned off in the first drain period DP1 and turned on in the second drain period.

In the first drainage period DP1, as the first valve 220, V1 is turned off, the heating water remaining in the heating pipe 11 of the mat 10 by the air injected by the air pumps 230, It can be mainly discharged.

Then, in the second drainage period DP2, the heating water remaining in the first valve 220 (V1) can be removed as the first valve 220 (V1) is turned on. For example, the heating water remaining in the piping between the first valve 220 (V1) and the tank inlet 220B of the heating water tank 200, the first valve 220, V1 and the 3-way branch pipe 300 Can be removed by the air injected by the air pump 230 (AP). As a result, it is possible to discharge the heating water more completely.

After the heating water is removed by the method as described above, the power of the boiler 20 can be turned off and the mat 10 and the boiler 20 can be separated and stored.

On the other hand, the activation point of the air pump 230, AP in the drain mode can be adjusted in consideration of the turn-on point of the second valve 240, V2.

11, the activation time point of the air pump 230, AP in the drainage period DP in which the drainage mode is executed is longer than the turn-on time of the second valve 240 (V2) for a predetermined time (for example, DELTA t).

In order to activate the air pumps 230 and AP after the second valves 240 and V2 are turned on as shown in FIG. 12, when the drainage mode is executed (S100), the second valves 240 and V2 It is possible to determine whether it is turned on (S110).

As a result of the determination, when the second valve 240 (V2) is turned on, the air pump 230, AP is activated and when the second valve 240 (V2) is not turned on, the second valve 240 You can wait until it turns on.

In this case, since the air pumps 230 and AP can be activated only when the second valves 240 and V2 are turned on, the heating water can be prevented from being suddenly ejected through the second valves 240 and V2 .

In order to more reliably discharge the heating water in the drainage mode, the second valve (240, V2) can be configured as a multiple valve.

For example, as in the case of FIG. 13, the second valve 240, V2 may include an automatic valve 240A and a manual valve 240B.

The automatic valve 240A is automatically turned on / off under the control of the control unit, and the manual valve 240B can be manually turned on / off by the user. Here, the manual valve 240B may be regarded as a cover as described above.

In this way, when the second valve 240, V2 is composed of multiple valves, it is possible that the air pump 230, AP is activated only when all the valves constituting the multiple valves are turned on.

For example, as in the case of FIG. 14, when the drainage mode is executed (S100), it can be determined whether or not the manual valve 240B of the second valve 240 (V2) is turned on (S200).

As a result of the determination, if the manual valve 240B is turned on, it is determined whether the automatic valve 240A of the second valve 240 (V2) is turned on (S220).

As a result of the determination, if both the manual valve 240B and the automatic valve 240A are turned on, the air pump 230, AP can be activated.

If it is determined in operation S200 that the manual valve 240B is not turned on, the user may be informed that the drainage mode has been executed but the manual valve 240B has not been turned on in operation S210.

In this case, the stability in the drainage mode can be further improved.

As described above, it is to be understood that the technical structure of the present invention can be embodied in other specific forms without departing from the spirit and essential characteristics of the present invention.

It should be understood, therefore, that the embodiments described above are to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than the foregoing description, And all changes or modifications derived from equivalents thereof should be construed as being included within the scope of the present invention.
