Hot water cushion

Technical Field

The present invention relates to a hot water mat, and more particularly, to a hot water mat capable of reducing noise and vibration.

Background

In general, a hot water mat is a mat for heating that circulates hot water heated to a set temperature in a boiler along a hot water pipe built in the hot water mat to perform heating.

The hot water mat as described above has advantages in that: the disadvantages of the conventional electric heating mat configured such that the electric heating wire is built in the hot water mat, that is, the generation of harmful electromagnetic waves and the danger of fire or electric shock due to the electric heating wire can be eliminated.

The hot water mat can be divided into: a motor circulation type hot water pad for circulating hot water by using an electric water pump, and a natural circulation type hot water pad for circulating hot water by using steam pressure.

Referring to fig. 1, the conventional hot water mat using the motor cycle method includes: a boiler part 10 for heating water; and a mat unit 20 for circulating the hot water heated in the boiler unit 10 to realize heating. The hot water heated in the boiler portion 10 is supplied to the mat portion 20 through the hot water supply pipe 11, and the hot water circulating in the mat portion 20 is recovered to the water tank portion 30 provided inside the boiler portion 10 through the hot water recovery pipe 12.

The boiler section 10 includes: a water tank part 30 for storing and heating water; a heating unit 40 which is provided inside the water tank unit 30 and has a heater 41 built therein; a water pump 50 for circulating and supplying the hot water heated by the heating part 40 to the pad 20 side; and a control part 60 for controlling the operation of the hot water mat. The water tank portion 30 is provided with a water level sensor 31 and a temperature sensor 32, and the heating portion 40 is provided with a heater 41, a bimetal 42 as a safety device for cutting off the flow of an overcurrent, and a temperature fuse 43. The conductive switch 71, the overcurrent fuse 72, and the freeze-break prevention switch 73 are electrically connected to the control unit 60.

A shunt valve 21 may be provided in the mat unit 20, and the shunt valve 21 shunts the hot water supplied to the mat unit 20 through the hot water supply pipe 11 to a plurality of flow paths to perform local heating.

Although fig. 1 shows an example in which the heating unit 40 is provided inside the tank unit 30, as shown in fig. 2, another embodiment may be configured such that: the heating part 40 is formed outside the water tank part 30, and heats water sent from the water pump 50 and supplies the water to the pad part 20.

Referring to fig. 3, the conventional natural circulation type hot water mat includes: a boiler section 10a for heating water; the mat unit 20a circulates hot water heated by the boiler unit 10a to realize heating. The hot water heated in the boiler portion 10a is supplied to the pad portion 20a through the first and second hot

water supply pipes

11a and 11b, and the hot water circulating in the pad portion 20a is collected in the tank portion 30a formed inside the boiler portion 10a through the first and second hot

water recovery pipes

12a and 12 b.

The boiler section 10a includes: a water tank unit 30a for storing and heating water; a first heating part 40a and a second heating part 40b respectively provided to the first hot water supply pipe 11a and the second hot water supply pipe 11 b; a first temperature sensor 13 and a second temperature sensor 14 formed at the first hot water recovery pipe 12a and the second hot water recovery pipe 12b, respectively, for detecting the temperature of the recovered water; and a control part 60a for controlling the operation of the hot water mat.

The first heating part 40a and the second heating part 40b are provided with a heater 41, a bimetal 42, and a thermal fuse 43. The control unit 60a is electrically connected to a conduction switch 71, an overcurrent fuse 72, and a freeze-break prevention switch 73.

The prior art regarding the hot water mat of the motor circulation type is disclosed in korean patent laid-open publication No. 10-0663967, and the prior art regarding the hot water mat of the natural circulation type is disclosed in korean patent laid-open publication No. 10-0948908.

In the conventional motor cycle hot water mat, when the mat unit 20 is divided into a plurality of zones to perform local heating in a desired zone, the bypass valve 21 is configured such that a user can manually rotate the control lever to set a hot water supply line. The prior art related thereto is disclosed in korean laid-open utility model No. 20-2009-0007072. However, in the case of manually operating the opening and closing of the hot water supply pipe, there are problems associated with inconvenience in use and difficulty in accurately controlling the temperature inside the mat 20.

In the case of the conventional natural circulation type hot water mat, when the mat unit 20a is heated in different zones, the supply of hot water through the first and second hot

water supply pipes

11a and 11b may be controlled by controlling the opening and closing operations of the first and

second circulation valves

33 and 34, but there are disadvantages as follows: since the pipes for supplying and recovering the hot water are formed as a pair, respectively, the pipe structure is complicated, and since the heaters 41 are provided at the first and second hot

water supply pipes

11a and 11b, respectively, the equipment cost is increased.

In the above-mentioned conventional hot water mat, vibration and noise may be generated in the motor in terms of the motor circulation manner, and thus there is a problem in that bedtime may be hindered, thereby reducing the satisfaction of consumers with the product.

102 and 103 is polymerized in the body of the hot water polymerization unit 108, and then discharged through the hot water discharge port 108c, and is collected to the water heating unit 110a through the hot water inflow port 109. As described above, the water recovered from the mat unit 200 is recovered to the water heating unit 110a after polymerization of the individual pipes, so that the pipe structure for recovering water can be simplified.

The hot water polymerization unit 108 is provided with: a first automatic valve 130 for opening and closing a pipe connecting the first recovered hot water connection port 108a and the hot water discharge port 108 c; the second automatic valve 150 opens and closes a pipe connecting the second recovered hot water connection port 108b and the hot water discharge port 108 c. In this case, the first automatic valve 130 and the second automatic valve 150 may be constituted by electromagnetic valves that automatically open and close the pipes according to whether or not current is applied based on a control signal of the control part 170. Therefore, when the user sets to heat only one of the divided regions of the mat unit 200, or sets to heat the entire regions, or sets to stop the heating operation, the control unit 170 sends corresponding control signals to the first automatic valve 130 and the second automatic valve 150 according to the heating mode set by the user, and accordingly, automatically performs the opening and closing operations of the first automatic valve 130 and the second automatic valve 150. That is, when heating the entire plurality of zones, the first automatic valve 130 and the second automatic valve 150 are controlled to be opened at the same time; when heating is performed only in one of the divided regions of the mat unit 200, the valve corresponding to the region is controlled to be opened, and the valve corresponding to the region not to be heated is controlled to be closed.

According to the above configuration, the present invention can improve the convenience of the installation operation for performing the zone heating of the mat and the reliability of the opening and closing operation of the duct for performing the zone heating, compared to the case where the zone heating is installed by the conventional manual operation.

In the above embodiment, the configuration in which the water recovered by the first and second hot

water recovery pipes

102 and 103 passes through the hot water polymerization unit 108 and is recovered in the water heating unit 110a has been described, but the hot water recovered by the first and second

automatic valves

130 and 150 may be recovered in the water heating unit 110a through separate flow paths.

That is, the first automatic valve 130 includes: a first hot water recovery connection port through which water recovered by the first hot water recovery pipe 102 flows; and a first hot water discharge port for discharging the water, which has flowed into the first automatic valve 130 through the first recovered hot water connection port, to the water heating unit 110a side. And, the second automatic valve 150 includes: a second hot water recovery connection port through which water recovered by the second hot water recovery pipe 103 flows; and a second hot water discharge port for discharging the water, which has flowed into the second automatic valve 150 through the second recovered hot water connection port, to the side of the water heating unit 110 a. The first hot water outlet and the second hot water outlet are connected to the water heating unit 110a through separate pipes.

The control part 170 controls the heating temperature of the heater 111 so that the temperature of the water detected from the first temperature sensor 140 and the temperature of the water detected from the second temperature sensor 160 reach the set target temperatures for the respective divided regions of the pad part 200.

The mat unit 200 is divided into a plurality of areas, so that heating can be performed in each area. In the present embodiment, as shown in fig. 5, the mat unit 200 is divided into a first area 200a and a second area 200b on both sides of a center line C of the plate 203, and the first area 200a is provided with a first hot water circulation pipe 201 and the second area 200b is provided with a second hot water circulation pipe 202.

A branch port 210 is provided in the mat unit 200, and the branch port 210 distributes the hot water flowing in through the hot water supply pipe 101 to the first and second hot

water circulation pipes

201 and 202.

The branch port 210 is formed of a T-shaped structure of a flow divider, one side of which is connected to the hot water supply pipe 101, and the other side of which is connected to the first and second hot

water circulation pipes

201 and 202 in such a manner that the first and second hot

water circulation pipes

201 and 202 face both sides. By providing the branch port 210 having the T-shaped structure, the hot water supply pipe 101 can be formed by a single pipe, and therefore, the pipe structure for supplying the hot water heated by the boiler unit 100 to the pad unit 200 side can be simplified.

Unexplained symbol 104 in fig. 6 denotes a power line, and unexplained symbol 181 in fig. 4 denotes an electric switch for blocking the supply of power in the case where the boiler portion 100 is reversed to one side; unexplained symbol 182 denotes an overcurrent fuse for blocking a power supply when an overcurrent is applied; unexplained symbol 183 denotes a freeze-crack preventing switch.

Fig. 10 is a perspective view of the first vibration isolator 300, and fig. 11 is a sectional configuration view of the first vibration isolator 300.

Referring to fig. 10 and 11, as described above, the first vibration isolation portion 300 applied to the present invention is positioned on the bottom surface of the casing 190 of the boiler unit 100 and contacts the installation surface, thereby preventing vibration of the boiler unit 100 from being transmitted to the installation surface.

The first vibration isolation portion 300 includes: a contact portion 310 contacting the installation surface in a disc-shaped structure; a lower fixing portion 320 located at an upper side of the contact portion 310, and having an upper surface contacting a bottom surface of the housing 190; an upper fixing part 330 positioned above the lower fixing part 320, and having a bottom surface contacting the inner bottom of the housing 190 to fix the first vibration isolating part 300; and a handle part 340 upwardly protruding from an upper surface of the upper fixing part 330.

The first vibration prevention part 300 is fastened and fixed to a fastening hole (not shown) formed in the bottom surface of the housing 190, and the handle part 340 is inserted into the fastening hole from the lower side in order to be easily fastened, and then the handle part 340 is pulled upward, and the upper fixing part 330 is fastened through the fastening hole.

In order to easily pass the upper fixing part 330 through the fastening hole, an upper surface thereof is formed as an inclined surface 331.

A gap corresponding to the thickness of the housing 190 is formed between the upper fixing portion 330 and the lower fixing portion 320, so that the upper fixing portion and the lower fixing portion are fixed in a fastened state as described above so as not to be easily detached.

The bottom surface of the contact portion 310 is formed with a concave suction surface 311, so that the boiler unit 100 is easily fixed to an installation surface.

Fig. 12 is a perspective view of the second vibration isolator 400, and fig. 13 is a sectional configuration view of the second vibration isolator 400.

Referring to fig. 12 and 13, respectively, the second vibration isolator 400 applied to the present invention includes: a body 410 having a through hole 460 formed at the center; an insertion fixing part 420 formed on the bottom surface of the body part 410 and having a diameter larger than that of the through hole part 460 so that the ends of the fixing

parts

190a, 190b, 190c protruding from the housing 190 can be inserted; an insertion groove 450 formed along the circumference of the outer surface of the central portion of the body portion 410 to allow a cradle (blacket) to be inserted; the buffer portion 440 is a groove formed in the center of the through hole 460.

The second vibration isolation part 400 is fixed in a state where the opposite side of the surface where the insertion fixing part 420 is formed is inserted into the insertion hole provided in the water tank part 110 or the bracket for fixing the first automatic valve 130 is inserted into the insertion groove 450.

A plurality of protrusions 430 are formed along the inner circumference of the through-hole 460 on the opposite side of the side where the insertion fixing part 420 is formed, so that the structure engaged with the protrusions 430 can be inserted and fixed as necessary.

The buffer portion 440 is configured to further increase the vertical elastic force of the body portion 410, and the diameter of the buffer portion 440 is larger than the diameter of the through hole 460.

The second vibration prevention portion 400 of the above-described structure can minimize the transmission of vibration generated from the first and second

automatic valves

130 and 150 and can minimize the transmission of vibration generated from the pump 120 to the water tank portion 110.

Fig. 14 is a perspective view of the third vibration prevention portion 500, and fig. 15 is a sectional configuration view of the third vibration prevention portion 500.

Referring to fig. 14 and 15, respectively, the third vibration prevention portion 500 includes: an upper coupling part 510 having a first diameter into which the hot water supply pipe 101 of the water tank part 110 can be inserted; and a lower coupling part 520 having a second diameter into which the water supply pipe of the water pump 120 can be inserted. At this time, the first diameter is generally larger than the second diameter, but the first diameter may be smaller depending on the design.

The lower end of the upper combining part 510 and the upper end of the lower combining part 520 are connected by means of a connecting part 530, and the connecting part 530 is an inclined structure, i.e., the connecting part with the lower combining part 520 is higher than the connecting part with the upper combining part 510.

The above-mentioned inclined connection 530 may further increase the buffering effect.

The upper combining portion 510, the lower combining portion 520, and the connecting portion 530 are integrally formed, and the material thereof may be rubber or silicon rubber.

The water pump 120 may be suspended at a lower side of the water tank part 110 by means of the third vibration prevention part 500, and may minimize the transmission of vibration generated by the operation of the water pump 120 to the water tank part 110.

Fig. 16 is a perspective view of the fourth vibration isolator 600 surrounding the water pump 120, and fig. 17 is a sectional configuration view of the fourth vibration isolator 600.

Referring to fig. 16 and 17, respectively, the fourth vibration prevention part 600 according to the present invention has a cylindrical structure capable of inserting the water pump 120 to the inside, and an exposure hole 610 is formed at a portion of an upper side surface of the fourth vibration prevention part 600 so that the aforementioned supply pipe 121 can be connected to a discharge port through which hot water is discharged from the water pump 120

In this manner, by using the fourth vibration isolation portion 600 surrounding the outer surface of the water pump 120, which generates vibration during operation, it is possible to minimize the transmission of the vibration of the water pump 120 to the outside.

The fourth vibration prevention part 600 may use rubber or silicon rubber, or may use sponge.

As described above, the present invention can minimize the generation of vibration by using the first to fourth

vibration prevention parts

300, 400, 500, 600 of an elastic material, thereby reducing the generation of noise.

In the above embodiment, the case where all of the first to fourth

vibration prevention parts

300, 400, 500, and 600 are used has been illustrated and described, but when one selected from the first to fourth

vibration prevention parts

300, 400, 500, and 600 is used, vibration and noise can be reduced.

In addition, the present invention can reduce the noise generated by the first automatic valve 130 and the second automatic valve 150 by changing the combination structure of the first automatic valve 130 and the second automatic valve 150.

Fig. 18 is a sectional view of the first automatic valve 130.

Referring to fig. 18, the first automatic valve 130 includes: a water inlet pipe 131; a water outlet pipe 132; a plunger 137 driven by means of current applied to a coil 135 wound around a bobbin (bobbin) portion 134 to adjust an opening degree between the water inlet pipe 131 and the water outlet pipe 132; a spring 136 restoring the plunger 137.

At this time, the water inlet pipe 131 and the water outlet pipe 132 are positioned on the upper side of the plunger 137. When the existing automatic valve is arranged, the plunger is positioned at a position higher than the water inlet pipe and the water outlet pipe. That is, the bobbin part and the coil wound around the bobbin part are also configured to be positioned higher than the water inlet pipe and the water outlet pipe so that the valve is closed when the plunger moves downward, but in the present invention, the water inlet pipe 131 and the water outlet pipe 132 are positioned higher than the other configurations and the valve is in a closed state when the plunger 137 is completely moved upward by the spring 136.

With such a difference in fastening structure, since the existing plunger and spring are disposed at a position higher than the water inlet pipe and the water outlet pipe through which water flows, and thus the portion is in a state of being filled with inflow air, relatively large noise is generated due to the influence of the friction coefficient, but in the present invention, since the plunger 137 and the spring 136 are disposed at a position lower than the water inlet pipe 131 and the water outlet pipe 132, water can flow into a space in which the plunger 137 and the spring 136 are received, and thus the friction coefficient can be reduced.

Therefore, the first automatic valve 130 and the second automatic valve 150 of the present invention can reduce the generation of noise compared to the conventional automatic valves.

A sensor fastening portion 138 communicating with the inlet pipe 131 is formed at the first automatic valve 130 so that the first temperature sensor 140 can measure the temperature of the hot water flowing through the inlet pipe 131. The second automatic valve 150 also includes a sensor fastening portion capable of fastening the second temperature sensor 160.

According to the invention, the following advantages are achieved: the generation of noise and vibration can be minimized when the automatic valve is used; the setting of the hot water circulation flow path for selectively supplying hot water to the divided regions of the mat unit 200 for district heating can be automatically controlled; the piping structure for supplying and recovering hot water can be simplified.
