That is, ) ≪ / RTI > number. 5, the heating temperature controller 104 may be configured as a pair of upper and lower buttons for each of the separation pipes 12 of the hot water mat 10. [

6 is an internal schematic view of a hot water supply device according to the present invention.

6, the hot water supply device 100 of the hot water mat 10 according to the present invention includes a storage tank 110, a heater 120, a pump 130, a valve 150, And may include a control unit 200.

The storage tank 110 stores a heat transfer fluid (for example, water, etc., hereinafter, the heat transfer fluid is limited to 'water' for convenience of explanation).

One side of the storage tank 110 may be formed with a water inlet 112 connected to the confluent pipe 16 of the hot water mat 10 to return water from the hot water mat 10. A water outlet 114 may be formed on the other side of the storage tank 110 so that hot water heated at a predetermined temperature in the storage tank 110 is directed toward the hot water mat 10. [ At this time, the hot water flow from the storage tank 110 to the valve 150 is one flow irrespective of the separation heating of the hot water mat 10, so that even if only one outlet 114 of the storage tank 110 is formed It is acceptable.

On the other hand, in the storage tank 110, an outflow temperature sensor for measuring an outflow temperature at the outlet 114 of the storage tank 110 and a low temperature, middle and high water level of the storage tank 110 are respectively measured Three water level sensors or the like may be installed.

The heater 120 may be installed in the storage tank 110 to heat the water in the storage tank 110, for example, by an electric heating method. In the case of the heater 120 of the electric heating type, in order to heat the water in the storage tank 110 in accordance with the heating temperature set through the heating temperature adjusting unit 104, 200 may receive information from the heating temperature controller 104 and the outflow temperature sensor and control the driving time and the driving voltage of the heater 120.

The pump 130 may be installed between the outlet 114 of the storage tank 110 and the valve 150 along with the hot water flow out of the storage tank 110. The pump 130 may be implemented by various driving methods, for example, a motor driving method.

FIG. 7 is a perspective view showing a part of the valve 150 of the hot water supply device 100 according to the present invention, and FIG. 8 is a schematic view showing the operation of the valve 150 of the hot water supply device 100 according to the present invention. to be.

As shown in FIGS. 7 and 8, the valve 150 controls the hot water flow from the storage tank 110 to the first and second separation pipes 12a and 12b of the hot water mat 10, respectively I will crack down. To this end, the valve 150 may include a valve body 160, a pair of packings 170a and 170b, and a pair of solenoids 180a and 180b.

The valve body 160 includes one inlet pipe 162 through which the hot water of the storage tank 110 is introduced through the pump 130 and one inlet pipe 162 through which the hot water of the hot water mat 10 flows, , 12b), i.e., first and second separation conduits. As described above, when the isolation pipes of the valve body 160 are formed as a pair, they can be arranged in a 'T' shape together with the single inlet pipe 162.

In the case of a 'T' -shaped design, the pair of separating ducts may be arranged opposite to each other and connected in a straight line, and the inlet pipe 162 may be connected to a connecting portion of the pair of separating ducts in a vertical direction. Accordingly, the valve 150 can be designed symmetrically about the inlet line 162, so that it is structurally simple and balanced, the hot water flow can be uniformly distributed through the valve 150, and the hot water flow resistance It is possible to meet the purpose of reducing the flow loss and reducing the noise.

Each of the separation lines includes a first conduit 165 connected to the inflow conduit 162 and a second conduit 165 extending from the end of the first conduit 165 and connected to the separation pipe 12 of the hot water mat 10, And a second conduit 166 formed with an outlet 166a through which the outlet 166a is formed. The end 165a of the first conduit 165 connected to the second conduit 166 may be formed to have a predetermined length protruding into the second conduit 166. In addition, the protruding portion of the first channel 165 may be formed to be at least as sharp as the end portion thereof becomes closer to the end. Therefore, even if the packing 170a and 170b are brought into contact with the protruding end of the first conduit 165, the hot water smoothly flows from the first conduit 165 to the second conduit 166 ). ≪ / RTI > The outlet 166a of the second conduit 166 may be formed in a direction perpendicular to the hot water flow through the first conduit 165 so that hot water flows through the packing 170a, , The solenoids (180a, 180b) and the like without being structurally interfered with. The outflow port 166a of the second conduit 166 may be formed as a conduit having a predetermined length along the outflow direction through the outflow port 166a of the second conduit 166. [ On the other hand, the second conduit 166 is opened on the opposite side to the first conduit 165, so that the solenoids 180a and 180b can be connected and coupled.

In the meantime, when the pair of the isolation pipes of the valve body 160 are formed as a pair, it is also possible to arrange them in a Y shape together with the single inlet pipe 162. At this time, The outlet port 166a may be formed in an oblique direction so as to correspond to the hot water flow through the first channel 165 and the 'Y' shape.

The packings 170a and 170b may be configured to correspond to the number of the separation pipes of the valve body 160 so that hot water flow through the separation pipes of the valve body 160 is interrupted, respectively. That is, the packings 170a and 170b may be formed as a pair corresponding to the first and second isolation pipes 164a and 164b of the valve body 160. [ The packings 170a and 170b may be formed of rubber or the like so as to be elastically deformed by the water pressure due to the hot water flow. The packings 170a and 170b are extended and formed so as to intermit the hot water flow through the first channel 165 according to the hot water flow through the first channel 165 and the pressing force of the solenoids 180a and 180b. And may be installed in the second channel 166. Particularly, the packing 170a and 170b may include a body 172 formed in the second conduit 166 and contacting an end of the first conduit 165, And an expansion part 174 interposed between the second channel 166 and the solenoids 180a and 180b. The body portion 172 of the packing 170a and 170b may have any shape as long as one side thereof can contact the end of the first channel 165. The main body 172 of the packing 170a and 170b may be formed in a cylindrical shape as shown in the figure. The main body 172 may have a smaller diameter or width than the second channel 166, The hot water may flow through the gap between the cap 166 and the body 172 of the packing 170a, 170b. The expansion part 174 of the packing 170a and 170b may be any shape as long as it can structurally block the second channel 166 and the solenoids 180a and 180b and seal the first channel 166 and the solenoids 180a and 180b so as not to leak. The expansion portions 174 of the packing 170a and 170b may be formed in a disk shape concentric with the body portion 172 of the packing 170a and 170b. The packing 170a and the packing 170b serve as a partition and seal between the second channel 166 and the solenoids 180a and 180b, Since the packings 170a and 170b can be fixed, it is very efficient in that the number of constituent parts such as sealing and packing fixing members can be reduced.

The solenoids 180a and 180b may also be paired in correspondence with the first and second isolation pipes 164a and 164b of the valve body 160. The solenoids 180a and 180b may be installed to face the first conduit 165 with the packing 170a and 170b as a center. That is, the first channel 165, the packings 170a and 170b, and the solenoids 180a and 180b may be arranged in a line. Accordingly, the packing 170a and 170b may be separated from the first channel 165 and the solenoid 180b depending on the difference between the water pressure due to the hot water flow through the first channel 165 and the pressing force of the solenoids 180a and 180b. 180a, and 180b. The solenoids 180a and 180b may be implemented in various manners, and preferably, the solenoids 180a and 180b may be implemented by an electromagnetic driving method as follows. That is, the solenoids 180a and 180b may include a solenoid body 184 and a flange 186. The solenoid body 184 is installed in a line with a predetermined distance from the packing 170a and 170b and generates a pressing force when power is applied thereto by the controller 200. [ The flange 186 may advance toward the packing 170a or 170b to press the packing 170a or 170b or move back from the packing 170a or 170b depending on the pressing force of the solenoid body 184 . The solenoids 180a and 180b may include a solenoid housing 182 in which the solenoid body 184 is embedded and which is structurally coupled to the body valve 150.

9 is a block diagram of a method of controlling a hot water supply apparatus according to the present invention.

9, the controller 200 controls the heating temperature controller 104, the first and second heating temperature sensors 14a and 14b, the heater 120, the outflow temperature sensor, the water level sensor, And the solenoids 180a and 180b of the valve 150. The hot water supply device 100 is a microcomputer that electronically controls the hot water supply device 100 as a whole. Particularly, in the present invention, the controller 200 controls the first and second separation pipes 12a and 12b of the hot water mat 10 in accordance with the selection of various users using the hot water mat 10 by dividing the hot water mat 10, And 12b, respectively, so that the hot water mat 10 can be separately heated.

The operation and effect of the hot water supply device according to one embodiment of the present invention will be described in detail with reference to FIGS. 1 to 10. FIG.

4 and 5, the heating temperature of the first and second separation pipes 12a and 12b of the hot water mat 10 (hereinafter, First and second heating temperatures "). At this time, the first and second heating temperatures may be set to the same temperature or different temperatures depending on the user's selection of the part of the hot water mat 10. For example, the first heating temperature may be set to 60 ° C, and the second heating temperature may be set to 40 ° C. (Hereinafter, for convenience of explanation, the first heating temperature is set to '60 ° C', and the second heating temperature is set to '40 ° C'.)

When the heating temperatures of the first and second separation pipes 12a and 12b of the hot water mat 10 are set through the heating temperature control unit 104, the heating temperature information is received by the control unit 200 do.

Then, the control unit 200 controls the driving of the heater 120 according to the received heating temperature information. In particular, the controller 200 controls the driving of the heater 120 so that the temperature of the hot water discharged from the storage tank 110 corresponds to a preset heating temperature. For example, the control unit 200 controls the driving time and the driving voltage of the heater 120 so that the outflow temperature of the storage tank 110 corresponds to the first heating temperature '60 ° C.'.

When the water in the storage tank 110 is heated by the heater 120 as described above, the hot water in the storage tank 110 is supplied to the storage tank 110 by the pump 130 controlled by the controller 200. [ (See FIG.

The hot water discharged from the storage tank 110 flows to the valve 150 through the pump 130 and flows into the first and second separation pipes of the hot water mat 10 12a, 12b. The temperature of the hot water supplied to the first and second separation pipes 12a and 12b of the hot water mat 10 is controlled by the temperature of the hot water discharged from the storage tank 110, And the first and second heating temperatures, respectively, set through the heating temperature controller 104. Therefore, the heating temperatures of the portions of the hot water mat 10 can be controlled independently of each other, so that the separate heating can be performed.

Hereinafter, the control of the operation of the valve 150 by the controller 200 will be described in detail.

As described above, when the first and second heating temperatures (i.e., 60 DEG C and 40 DEG C) are different from each other, the controller 200 controls the operation of the valve 150 as follows.

The first separation pipe connected to the first separation pipe 12a of the hot water mat 10 having a high heating temperature is continuously opened and the second separation pipe 12b of the hot water mat 10, And the second separation pipe connected thereto is intermittently opened while being repeatedly opened and closed in accordance with the second heating temperature set. Accordingly, the first separation pipe 12a of the hot water mat 10 continuously receives the hot water of the '60 ° C' which is the first heating temperature set at the outgoing temperature of the storage tank 110, The heating temperature of the first separation pipe 12a of the evaporator 10 is also kept at 60 ° C. On the other hand, although the hot water of '60 ° C' is supplied to the second pipe of the hot water mat 10, it is supplied intermittently so that the heating temperature of the second separation pipe 12b of the hot water mat 10 is finally set And can be controlled to a second heating temperature '40 ° C'.

At this time, the controller 200 may intermittently open the second separation pipe 164b of the valve 150 according to the pre-stored opening / closing cycle of the second heating temperature. More specifically, the higher the second heating temperature set through the heating temperature controller 104, that is, the smaller the difference between the second heating temperature and the first heating temperature, The opening time of the separation pipe 164b is relatively longer than the closing time, and as the set second heating temperature becomes lower, that is, the difference between the second heating temperature and the first heating temperature becomes larger, The opening time of the separation pipe 164b can be made shorter than the closing time.

Alternatively, the control unit 200 determines whether the measured heating temperature of the second separation pipe 12b of the hot water mat 10 measured through the second heating temperature sensor 14b of the hot water mat 10 and the measured second heating temperature So that the second separation pipe 164b of the valve 150 can be opened intermittently. That is, when the actual heating temperature measured by the second heating temperature sensor 14b is lower than the second heating temperature, the second separation pipe 164b of the valve 150 is opened, and the second heating temperature When the measured heating temperature by the sensor 14b is higher than the second heating temperature, the second separation pipe 164b of the valve 150 can be closed.

In addition, the controller 200 controls the solenoids 180a and 180b of the valve 150 to be turned on / off when the second separation line 164b of the valve 150 is opened or closed, ), The driving of the pump 130 can be stopped. Therefore, since the driving of the pump 130 is stopped while the flange 186 of the solenoids 180a and 180b of the valve 150 is moved back and forth, the flow resistance due to the pressing force change of the packing 170a and 170b Noise can be prevented.

On the other hand, if the first and second heating temperatures are set to the same temperature, the first and second separation lines 164a and 164b of the valve 150 can be continuously opened.

Hereinafter, the intermittent opening control operation of the second separation pipe 164b of the valve 150 will be described in detail.

8, when the second solenoid 180b is turned on, the flange 186 of the second solenoid 180b advances toward the second packing 170b and presses the second solenoid 180b, The second packing 170b is elastically deformed even if water pressure is applied to the second packing 170b by the hot water flow through the first channel 165 of the second separation pipe 164b of the valve 150 So that the first channel 165 is blocked. Thus, although the hot water flow through the second separation line 164b of the valve 150 is limited, the first separation of the valve 150, which is continuously opened as shown by the solid line in FIG. 8, Hot water is continuously supplied to the first separation pipe 12a of the hot water mat 10 through the pipeline 164a.

On the other hand, when the power of the second solenoid 180b is turned off, the flange 186 of the second solenoid 180b is retracted from the second packing 170b as shown by a dotted line in FIG. The second packing 170b is not pressed by the second packing 170b due to the water pressure due to the hot water flow through the first channel 165 of the second separation pipe 164b of the valve 150, The hot water flows from the first conduit 165 of the second separation conduit 164b of the valve 150 to the second conduit 166 and the outlet 166a of the second conduit 166 is elastically deformed, To the second separation pipe (12b) of the hot water mat (10). Of course, hot water is continuously supplied to the first separation pipe 12a of the hot water mat 10 through the first separation pipe 164a of the valve 150. [

10, while the power of the second solenoid 180b is turned on / off, the controller 200 sets the driving voltage of the second solenoid 180b to a predetermined time (T1, t3). Therefore, since the flange 186 of the second solenoid 180b is gradually moved forward and backward, the noise due to the sudden change in the flow resistance as well as the operation noise of the second solenoid 180b itself can be prevented.

10, the flange 186 of the second solenoid 180b is advanced toward the second packing 170b to close the second separation pipe 164b of the valve 150 The control unit 200 controls the first solenoid 180b to be turned on when the power of the second solenoid 180b is turned on for a predetermined time t1, The driving voltage of the solenoid 180b is raised to the initial rated voltage V1.

Further, when the predetermined time t2 is reached after the drive voltage of the second solenoid 180b reaches the initial rated voltage, the controller 200 controls the second solenoid 180b until the power of the second solenoid 180b is turned off The driving voltage of the valve 150 is lowered from the initial rated voltage V1 to the maintaining rated voltage V2 to maintain the ON state of the power supply of the second solenoid 180b. Therefore, even if the driving voltage of the second solenoid 180b is lowered to the sustaining voltage V2 after the second separation line 164b of the valve 150 is closed by the second solenoid 180b, The closed state of the second isolation conduit 164b of the valve 150 can be continuously maintained and the electricity can be saved and the effect of reducing the heat generation temperature according to the electrical resistance of the solenoids 180a and 180b .

In contrast, when the first heating temperature is set relatively low and the second heating temperature is set high, the control unit 200 determines that the outflow temperature of the storage tank 110 is higher than the second heating temperature The second separation line 164b of the valve 150 is continuously opened and the first separation line 164a of the valve 150 is intermittently operated as described above The valve 150 may be controlled so as to be opened.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the present invention is not limited to the disclosed exemplary embodiments. It should also be understood that many modifications and variations are possible without departing from the scope of the invention, as would be understood by one of ordinary skill in the art.
