Technical Field

[0001] The present invention relates to the field of pipeline water transportation, and in particular to a wall-mounted boiler system. Background Art

[0002] The wall-mounted boiler system is a water heater that uses natural gas as energy. It has powerful home central heating functions and can meet the heating needs of multiple rooms. Each room can set a comfortable temperature as needed, and the heating can be turned off in a certain room as needed. It can also provide a large flow of constant temperature sanitary hot water for use in home bathing, kitchen and other places.

[0003] The power element of the existing wall-mounted boiler system is set close to the water inlet of the bathroom, and the water inlet of the bathroom needs to be connected to the tap water pipe.

[0044] See Figure 1 The present invention provides a wall-mounted boiler system for meeting the heating needs of each room and providing constant temperature sanitary hot water for use in family bathing, kitchen and other places.

[0045] The wall-mounted boiler system 100 includes a heat exchanger 201, an inlet and outlet water valve group 100a, and a power element 80. The inlet and outlet water valve group 100a is connected to the heat exchanger 201. The inlet and outlet water valve group 100a includes a valve body assembly 100b. The valve body assembly 100b is provided with a bathroom water inlet 4211 and a bathroom water outlet 14. Compared with the bathroom water outlet 14, the power element 80 is arranged closer to the bathroom water inlet 4211. The power element 80 is located at one end of the heat exchanger 201 away from the bathroom water inlet 4211 and close to the bathroom water outlet 14, and is connected to the valve body assembly 100b.

[0046] It can be understood that during installation, since the bathroom water inlet 4211 is usually arranged closer to the wall than the bathroom water outlet 14, the present invention arranges the power element 80 away from the bathroom water inlet 4211 compared to the bathroom water outlet 14, so that the power element 80 is arranged away from the wall, thereby allowing the wall-mounted boiler system 100 to have sufficient space to connect other heat sources to the power element 80.

[0047] Specifically, the inlet and outlet valve assembly 100a includes a first valve 101 and a second valve 401, which are separately arranged. Specifically, the second valve 401 includes a second valve body 40, and the first valve 101 includes a first valve body 10. The first valve body 10 and the second valve body 40 form a valve assembly 100b. The first valve body 10 and the second valve body 40 are respectively arranged at opposite ends of the heat exchanger 201. The first valve body 10 is arranged at the end of the heat exchanger 201 closest to the power element 80, and the second valve body 40 is arranged at the end of the heat exchanger 201 away from the power element 80. The bathroom water inlet 4211 is provided on the second valve body 40, and the bathroom water outlet 14 is provided on the first valve body 10. The first valve body 10 is provided with a power interface 13, which is connected to the power element 80. The power element 80 can be a power element such as a water supply pump, a water transfer pump, or a circulating water pump.

[0048] The power interface 13 is disposed on a side of the first valve body 10 close to the power element and is disposed toward the power element 80 to facilitate connection with the power element 80 .

[0049] Heat exchanger 201 includes a heating channel (not shown) and a bathroom channel (not shown). First valve body 10 defines a first heat exchange port 11 and a second heat exchange port 12 connected to power port 13. Both first and second heat exchange ports 11 and 12 are connected to heat exchanger 201. Second valve body 40 defines a third and fourth heat exchange ports 44 and 45. Both third and fourth heat exchange ports 44 and 45 are connected to heat exchanger 201. One end of the heating channel communicates with the second heat exchange port 12 and the other with the third heat exchange port 44. The bathroom channel communicates with the first heat exchange port 11 and the other with the fourth heat exchange port 45. Water in the heating channel exchanges heat with water in the bathroom channel in heat exchanger 201.

[0050] First valve body 10 defines a water outlet channel 15, one end of which connects to first heat exchange port 11 and the other end to bathroom outlet 14. After being heated, water in heat exchanger 201 flows out of first heat exchange port 11, into water outlet channel 15, and out of bathroom outlet 14.

[0051] The water outlet channel 15 is linear, that is, the water outlet channel 15 does not turn, so that the water outlet channel 15 has enough space to arrange other components.

[0052] The bathroom water outlet 14 is located at one end of the first valve body 10 away from the first heat exchange interface 11, that is, the bathroom water outlet 14 and the first heat exchange interface 11 are located at both ends of the first valve body 10, so that the water outlet channel 15 is long enough to have enough space to install other components.

[0053] The direction of the bathroom water outlet 14 is perpendicular to the direction of the first heat exchange interface 11 , that is, the bathroom water outlet 14 is arranged downward to facilitate connection with external bathroom equipment.

[0054] The first valve body 10 is also provided with a third measurement interface (not shown), which communicates with the water outlet channel 15. This interface is positioned close to the first heat exchange interface 11, thereby leaving more space for other components. A third measurement element 17 is located within the third measurement interface to monitor the status of water flowing out of or into the heat exchanger 201, such as its pressure and temperature. This third measurement element 17 can be a thermistor temperature sensor, a platinum resistance thermometer, a thermocouple, a pressure sensor, or a measurement element capable of simultaneously measuring both temperature and pressure.

[0055] The third measurement interface is located on a side of the first valve body 10 away from the first heat exchange interface 11, and faces oppositely to the first heat exchange interface 11. Placing the third measurement interface on the front side of the first valve body 10 facilitates the connection of the third measurement element 17 and prevents the third measurement interface from being blocked by the heat exchanger 201.

[0056] See Figure 2 and Figure 6 A protrusion 16 is provided on the first valve body 10, and the third measuring interface is opened on the protrusion 16. The first valve 101 also includes a pressure plate 20, which is provided on the protrusion 16 and can rotate relative to the protrusion 16 to limit or release the third measuring element 17.

[0057] A threaded hole (not shown) is provided on the protrusion 16, and a groove and a through-hole (not shown) are provided on the pressure plate 20. The screw passes through the through-hole and then extends into the threaded hole. The third measuring element 17 is provided in the third measuring interface. The pressure plate 20 is rotated so that the third measuring element 17 passes into the groove, and then the screw is tightened to fix the pressure plate 20 on the protrusion 16. When the third measuring element 17 needs to be replaced, the screw is slightly loosened and the pressure plate 20 is rotated to release the limit on the third measuring element 17, making it easier to install and replace.

[0058] See Figure 3 、 Figure 4 and Figure 5 The wall-mounted boiler system 100 further includes a water flow sensor 30 , one end of which extends into the water outlet channel 15 for measuring the water flow in the water outlet channel 15 .

[0059] In one embodiment, the water flow sensor 30 is an impeller-type water flow sensor 30 , which has a simple structure, low cost, and high accuracy.

[0060] Relative to the first heat exchange interface 11, the water flow sensor 30 is disposed close to the bathroom water outlet 14. Along the direction of water flow, the front end of the impeller of the water flow sensor 30 can have sufficient and stable space to promote the rotation of the impeller.

[0061] The second valve 401 also includes a three-way valve core 50. The second valve body 40 is provided with an inlet interface 43 and a heating water outlet 46. The three-way valve core 50 is arranged in the second valve body 40 and can move along the axial direction of the second valve 401 to selectively connect or disconnect the inlet interface 43 with the third heat exchange interface 44 and the heating water outlet 46.

[0062] See Figure 7 The second valve body 40 includes a three-way valve body 41 and a side valve body 42, which are interconnected and integrally formed. A heating water outlet 46 and an inlet port 43 are provided on the three-way valve body 41. The third and fourth heat exchange ports 44 and 45 are provided on the rear side of the second valve body 40. The side valve body 42 is located on the side of the three-way valve body 41 closest to the power element 80.

[0063] It can be understood that the third heat exchange interface 44 and the fourth heat exchange interface 45 are arranged on the rear side of the side valve body 42 to facilitate connection with the heat exchanger 201, and the present invention arranges the three-way valve body 41 on the side of the side valve body 42 away from the power element 80, which can prevent the three-way valve body 41 from interfering with the first valve 101; at the same time, the three-way valve body 41 and the three-way valve core 50 are arranged on the second valve 401, which can simplify the structure of the first valve 101 and reserve a position for setting the power interface 13 for the first valve 101.

[0064] The side valve body 42 includes a valve body 421, which is connected to the three-way valve body 41. The third heat exchange interface 44 and the fourth heat exchange interface 45 are both provided on the valve body 421. The valve body 421 has a water inlet channel 4212 and a flow channel 4213. The flow channel 4213 is connected to the bathroom water inlet 4211 and the fourth heat exchange interface 45, respectively. The water inlet channel 4212 is connected to the third heat exchange interface 44.

[0065] The valve body 421 is provided with a first measurement port 4214 and a second measurement port (not shown). Both are located on the side of the valve body 421, away from the heat exchanger 201. The orientations of the first and second measurement ports are opposite to those of the first and second heat exchange ports 11 and 12, respectively. The first measurement port 4214 communicates with the water inlet channel 4212, while the second measurement port communicates with the flow channel 4213. Both the first and second measurement ports are used to connect to a first measurement element. The first measurement element in each of the first and second measurement ports is used to monitor water conditions, such as pressure and temperature.

[0066] See Figure 8 and Figure 9 The wall-mounted boiler system 100 also includes a water supply valve core 60, which is connected to the valve body assembly 100b and can move within the valve body assembly 100b to control the bathroom water inlet 4211 to supply water to the heating channel to prevent water shortage in the heating channel.

[0067] Along the water flow direction, the water flow sensor 30 is positioned away from the bathroom water inlet 4211 relative to the water replenishment valve core 60. When water is replenished from the bathroom water inlet 4211 to the heating duct, the water enters the heating duct directly from the bathroom water inlet 4211 and does not pass through the water flow sensor 30, thus preventing misjudgment by the water flow sensor 30. It is understood that if, along the water flow direction, water first passes through the water flow sensor 30 during replenishment, the water flow sensor 30 would mistakenly interpret the water flow as water entering from the bathroom water inlet 4211 into the flow channel 4213, then flowing into the bathroom duct, and then out of the bathroom water outlet 14.

[0068] In one embodiment, the water flow sensor 30 is disposed within the water outlet channel 15, that is, within the first valve 101. The second valve body 40 further includes a water replenishment valve body 422 connected to the valve body 421. The water replenishment valve body 422 is disposed on the side of the valve body 421 away from the heat exchanger 201. The valve body 421 defines a water replenishment channel 4221, which communicates with the water inlet channel 4212. One end of the water replenishment valve core 60 extends into the water replenishment valve body 422 and is movable within the water replenishment valve body 422 to connect or disconnect the flow channel 4213 from the water replenishment channel 4221, allowing the flow channel 4213 to replenish water to the water inlet channel 4212 through the water replenishment channel 4221. By arranging the water supply valve body 422 and the water supply valve core 60 on the second valve 401, the water supply valve body 422 and the water supply valve core 60 are no longer required on the first valve 101, thereby simplifying the structure of the first valve 101 and ensuring that the first valve 101 has sufficient space to arrange the power interface 13.

[0069] The water replenishment valve body 422 defines a water replenishment hole 4222, which communicates with the water replenishment channel 4221. The water replenishment valve core 60 is movable to block the water replenishment hole 4222. When the water replenishment valve core 60 blocks the water replenishment hole 4222, the flow channel 4213 communicates with the water replenishment channel 4221 via the water replenishment hole 4222. When water replenishment is not required, the water replenishment valve core 60 moves to block the water replenishment hole 4222, isolating the flow channel 4213 from the water replenishment channel 4221 and, consequently, from the water inlet channel 4212.

[0070] A portion of the valve body 421 extends toward the side away from the third heat exchange interface 44, and the water supply valve body 422 is connected to the side of the valve body 421 away from the third heat exchange interface 44, that is, the water supply valve body 422 is located on the front side of the second valve 401, thereby reducing the overall width of the second valve 401.

[0071] The plane passing through the central axis of the bathroom water inlet 4211 and perpendicular to the axis of the first heat exchange interface 11 is defined as the first plane. The orthographic projection of the water supply valve core 60 on the first plane at least partially overlaps with the orthographic projection of the bathroom water inlet 4211 on the first plane. This configuration can further reduce the overall width of the second valve 401.

[0072] The axis of the water supply valve core 60 is parallel to the axis of the bathroom water inlet 4211. When installing the second valve 401, it is convenient to extend the water supply valve core 60 out of the sheet metal of the entire machine, and the extended part is long, which is convenient for the installer to operate.

[0073] The water supply channel 4221 is vertically arranged to the water inlet channel 4212 , and the processing technology is simpler than the inclined water supply channel 4221 .

[0074] See Figure 10 and Figure 11Furthermore, the three-way valve body 41 has a valve cavity 411, the three-way valve core 50 is arranged in the valve cavity 411, and a sleeve 412 is provided in the valve cavity 411. The cooperation between the three-way valve core 50 and the sleeve 412 divides the valve cavity 411 into a first cavity 4111, a second cavity 4112 and a heating cavity 4113. The first cavity 4111 is connected to the inlet interface 43, the second cavity 4112 is connected to the water inlet channel 4212, and the heating cavity 4113 is connected to the heating water outlet 46. The three-way valve core 50 can cooperate with the sleeve 412 to selectively block the gap between the second cavity 4112 and the first cavity 4111 or the gap between the first cavity 4111 and the heating cavity 4113.

[0075] The three-way valve core 50 includes a valve stem 51, a first sealing seat 52, and a second sealing seat 53. The sleeve 412 includes a first portion 4121 and a second portion 4122. The first portion 4121 and the second portion 4122 are respectively sealed to the inner wall of the valve chamber 411. The first portion 4121 is located between the first chamber 4111 and the second chamber 4112, and the second portion 4122 is located between the first chamber 4111 and the heating chamber 4113. The first sealing seat 52 can block the first portion 4121, and the second sealing seat 53 can block the second portion 4122. The valve stem 51 is respectively disposed within the first sealing seat 52 and the second sealing seat 53. The valve stem 51 can move axially along the three-way valve body 41, thereby driving the first sealing seat 52 and the second sealing seat 53 to move axially along the second valve 401. When the valve stem 51 moves upward, the first sealing seat 52 blocks the first part 4121, and the second sealing seat 53 is spaced apart from the second part 4122. At this time, the inlet interface 43, the first cavity 4111, the heating cavity 4113 and the heating water outlet 46 are connected; when the valve stem 51 moves downward, the second sealing seat 53 blocks the second part 4122, and the first sealing seat 52 is spaced apart from the first part 4121. At this time, the inlet interface 43, the first cavity 4111, the second cavity 4112, the water inlet channel 4212 and the first heat exchange interface 11 are connected, thereby realizing three-way switching.

[0076] The second valve 401 further includes a drive mechanism 70, which is disposed outside the three-way valve body 41 and connected to the valve stem 51. The drive mechanism 70 is capable of driving the three-way valve core 50 to perform up and down reciprocating motion. A first elastic member 54 is disposed between the first portion 4121 and the drive mechanism 70, and a second elastic member 55 is disposed between the second portion 4122 and the first portion 4121. Both the first elastic member 54 and the second elastic member 55 are sleeved outside the valve stem 51 and are used to reset the three-way valve core 50. In this embodiment, the drive mechanism 70 is a synchronous motor. In other embodiments, depending on the design of the three-way valve core 50, the drive mechanism 70 may alternatively be a stepping motor or other drive mechanism 70.

[0077] A first connecting hole 4114 is provided on the wall of the heating chamber 4113, and a second connecting hole 4115 is provided on the wall of the second chamber 4112. The second valve body 40 also includes a bypass valve body 47, which has a bypass flow channel 471 and a flow channel 4213. The bypass flow channel 471 and the flow channel 4213 are connected to the heating chamber 4113 through the first connecting hole 4114, and are connected to the second chamber 4112 through the second connecting hole 4115, thereby connecting to the water inlet channel 4212. When the water pressure in the inlet interface 43 is relatively high, the three-way valve core 50 cannot move downward due to the high pressure, and the driving mechanism 70 will continue to work, causing damage to the driving mechanism 70. The bypass flow channel 471 and the flow channel 4213 can increase the pressure in the second chamber 4112, thereby preventing the three-way valve core 50 from being unable to move downward due to the high pressure. In addition, when dry burning occurs due to lack of water in the heat exchanger 201, water is replenished to the water outlet flow channel 4213 through the bypass flow channel 471 and the flow channel 4213, thereby replenishing water into the heat exchanger 201.

[0078] The bypass valve body 47 is arranged on a side of the three-way valve body 41 away from the second valve body 40, which is convenient for maintenance. During maintenance, the entire three-way valve body 41 does not need to be removed.

[0079] The axis of the bypass valve body 47 is tilted relative to the axis of the three-way valve body 41 , so that the bypass valve body 47 is close to the three-way valve body 41 , reducing the width of the second valve 401 and making its structure compact.

[0080] Preferably, a one-way valve core 472 is provided in the bypass channel 471 and the channel 4213, which not only realizes the water replenishment function, but also prevents water from flowing back from the second chamber 4112 to the heating chamber 4113.

[0081] The wall-mounted boiler system 100 also includes a heating module 901 and a radiator 902. The heating module 901 is located at the end of the heat exchanger 201 near the power element 80 and is connected to the inlet of the power element 80. One end of the radiator 902 is connected to the heating outlet water, and the other end is connected to the inlet of the power element 80. Radiator 902 is used for heating the user. The heating module 901 is a solar panel or other heat source that can provide heat, which can save energy for the wall-mounted boiler system 100.

[0082] The wall-mounted boiler system 100 further includes a combustion chamber 301 , one end of which is connected to the inlet interface 43 , and the other end of which is connected to the outlet of the power element 80 .

[0083] During operation, some water enters the bathroom channel through the bathroom water inlet 4211, while some water flows out of the combustion chamber 301 and into the inlet port 43. Some of the water entering the inlet port 43 enters the heating channel through the inlet channel 4212. The water in these two channels exchanges heat in the heat exchanger 201. After the water enters the inlet port 43 and is heated, it re-enters the combustion chamber 301. The water flowing out of the bathroom water outlet 14 and is heated is then used by the user for bathing. Some of the water entering the inlet port 43 flows out of the heating outlet 46, enters the radiator 902, provides heat to the external device, and then returns to the combustion chamber 301 for heating via the power element 80.

[0084] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
