Description

Technical Field

[0001] This invention relates to the field of dual-purpose wall-hung boiler technology, and more specifically, to a heat storage pressurized water tank for a dual-purpose wall-hung boiler in a single-story residential building. Background Technology

[0002] Current wall-hung boiler manufacturers focus on energy efficiency, but neglect the importance of domestic hot water. Generally, wall-hung boilers solve the domestic hot water problem by adding a 200L coil tank to the boiler system. However, this presents another problem: the coil tank is very large, and single-level users lack the space to install it (a 200L coil tank requires one square meter), resulting in high costs and complex installation. During peak water usage periods, issues such as insufficient hot water supply, unstable water temperature, and unstable water flow can occur. Furthermore, existing wall-hung boilers ignite and heat even when the hot water tap is turned on briefly, leading to frequent ignition switching and making them inefficient.

[0003] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention

[0004] In response to the problems in related technologies, this invention proposes a dual-purpose wall-mounted boiler heat storage pressurized water tank for single-story residential buildings, in order to overcome the aforementioned technical problems existing in the prior art.

[0005] The technical solution of this invention is implemented as follows:

[0006] A dual-purpose wall-mounted boiler heat storage pressurized water tank for single-story residential buildings includes: a water tank outer shell, an inner tank liner disposed inside the outer shell, an inner tank top cover disposed at the top of the inner tank liner, an inner tank bottom cover disposed at the bottom of the inner tank liner, a support column disposed at the bottom of the inner tank bottom cover, a water pump disposed on the side of the support column, a controller disposed at the bottom of the support column, the water pump being electrically connected to the controller, an inlet bend disposed on one side of the water pump, and the other end of the inlet bend... The pump extends through the bottom cover of the inner tank and into the inner cavity of the water tank. A return water inlet is located on the other side of the pump. An electric heating element is installed at the top of the support column and within the inner cavity of the water tank. The electric heating element is electrically connected to the controller. A super magnesium rod is installed between the electric heating elements. A temperature sensor is installed at the top of the support column. A connecting pipe is located on the lower side of the inner tank. A water flow sensor is installed inside the connecting pipe and is electrically connected to the controller. The other end of the first connecting pipe is equipped with a three-way valve, which is electrically connected to the controller. The top of the three-way valve has a hot water inlet for the wall-mounted boiler, and the bottom of the three-way valve has a tap water inlet. A second connecting pipe is installed at the upper part of the inner tank. An anti-electric shock wall is installed inside the second connecting pipe. The other end of the second connecting pipe is equipped with a water valve, and the other end of the water valve has a hot water outlet connected to the hot water outlet pipe of the water tank. Several water usage points are connected to the hot water outlet pipe of the water tank. The other end of the hot water outlet pipe of the water tank is connected to the hot water return pipe of the water tank, and the other end of the hot water return pipe of the water tank is connected to the return port. The end of the tap water inlet is connected to the first cold water pipe of the tap water. The other end of the first cold water pipe of the tap water is equipped with a tap water pump, and the other end of the tap water pump is connected to the second cold water pipe of the tap water. The port of the hot water inlet of the wall-hung boiler is connected to the hot water inlet pipe of the wall-hung boiler. The top of the second cold water pipe of the tap water and the hot water inlet pipe of the wall-hung boiler are equipped with the wall-hung boiler water heater.

[0007] Furthermore, the inner surface of the water tank is provided with an enamel layer.

[0008] Furthermore, the interior of the water tank shell is equipped with a high-density polyurethane insulation layer.

[0009] Furthermore, the water pump is a brushless water pump.

[0010] The beneficial effects of this invention are as follows: After installation, the tap water pump is started to fill and vent water into the inner tank through the tap water inlet. Once the inner tank is full, power is supplied, and the controller sets the water temperature inside the inner tank. The electric heating element automatically heats the tap water to the set temperature and then automatically stops working. Simultaneously, the brushless water pump immediately starts working, delivering the hot water from the inner tank to each water point. When the homeowner turns on the hot water tap, constant-temperature hot water will flow out immediately. When the homeowner uses water for a long time or in large quantities, the temperature sensor automatically identifies the real-time water temperature inside the inner tank, or the water flow sensor detects how long the homeowner has used hot water and switches the operation of the three-way valve accordingly. When the temperature sensor detects that the actual temperature inside the inner tank is 15 degrees Celsius lower than the set temperature, the data detected by the temperature sensor is transmitted to the controller to activate the three-way valve, opening the hot water inlet of the wall-mounted boiler, allowing the wall-mounted boiler water heater to ignite and replenish the water tank with high-temperature hot water. When the water flow sensor detects that the homeowner has continuously used hot water for a certain number of seconds, the data detected by the water flow sensor is transmitted to the controller to activate the three-way valve, opening the hot water inlet of the wall-mounted boiler and allowing the boiler to ignite and replenish the water tank with high-temperature hot water. The advantages of this invention are: instant hot water; regardless of the number of water outlets in the house, hot water is available as soon as the hot water tap is turned on; constant water temperature; and the ability to meet the needs of multiple simultaneous water uses, with no change in flow rate or temperature even when two or more water outlets are using water at the same time. It prevents the wall-mounted boiler from frequently switching ignition; if hot water is needed for a short time, the boiler will not ignite but will continue to supply heating mode; if the water tank temperature is insufficient or the set time is reached, the boiler will automatically start to supply domestic hot water. By using a heat storage pressurized water tank in the wall-mounted boiler instead of a coil water tank, the footprint is reduced, solving the problem of insufficient installation space in single-level residential homes.

[0020] According to an embodiment of the present invention, a pressure-bearing water tank for dual-purpose wall-mounted boilers in single-story residential buildings is provided.

[0021] like Figure 1-5As shown, the dual-purpose wall-mounted boiler heat storage pressurized water tank for single-story residential buildings according to an embodiment of the present invention includes a water tank shell 10, an inner tank liner 9 disposed inside the water tank shell 10, an inner tank top cover 18 disposed at the top of the inner tank liner 9, an inner tank bottom cover 16 disposed at the bottom of the inner tank liner 9, a support column 27 disposed at the bottom of the inner tank bottom cover 16, a water pump 8 disposed on the side of the support column 27, a controller 5 disposed at the bottom of the support column 27, the water pump 8 being electrically connected to the controller 5, and an inlet bend 15 disposed on one side of the water pump 8. The other end of 15 passes through the bottom cover 16 of the inner tank and extends into the inner cavity of the inner tank 9. A return water inlet 4 is provided on the other side of the water pump 8. An electric heating tube 6 is installed at the top of the support column 27 and inside the inner cavity of the inner tank 9. The electric heating tube 6 is electrically connected to the controller 5. A super magnesium rod 7 is installed between the electric heating tubes 6. A temperature sensor 29 is installed at the top of the support column 27. A connecting pipe 14 is installed on the lower side of the inner tank 9. A water flow sensor 17 is installed inside the connecting pipe 14 and is electrically connected to the controller 5. A three-way valve 11 is provided at the other end of the connecting pipe 14. The three-way valve 11 is electrically connected to the controller 5. A hot water inlet 2 for the wall-mounted boiler is provided at the top of the three-way valve 11, and a tap water inlet 3 is provided at the bottom of the three-way valve 11. A second connecting pipe 28 is provided at the upper part of the inner tank 9. An anti-electric shock wall 12 is provided inside the second connecting pipe 28. A water valve 13 is provided at the other end of the second connecting pipe 28. A hot water outlet 1 is provided at the other end of the water valve 13, and a hot water outlet pipe 25 for the water tank is connected to the end of the hot water outlet pipe 25. Several water-using devices are connected to the hot water outlet pipe 25. Point 24, the other end of the hot water outlet pipe 25 of the water tank is connected to the hot water return pipe 22 of the water tank, the other end of the hot water return pipe 22 of the water tank is connected to the return port 4, the end of the tap water inlet 3 is connected to the first tap water cold water pipe 26, the other end of the first tap water cold water pipe 26 is provided with a tap water pump 21, the other end of the tap water pump 21 is connected to the second tap water cold water pipe 23, the port of the hot water inlet 2 of the wall-hung boiler is connected to the hot water inlet pipe 20 of the wall-hung boiler, and the top of the second tap water cold water pipe 23 and the hot water inlet pipe 20 of the wall-hung boiler is provided with a wall-hung boiler water heater 19.

[0022] In one embodiment, the surface of the inner tank 9 is provided with an enamel layer to prevent corrosion of the inner tank 9 and thus increase the service life of the equipment.

[0023] In one embodiment, the water tank outer shell 10 is provided with a high-density polyurethane insulation layer inside, which in turn keeps the hot water in the inner tank 9 warm, thereby reducing heat loss, reducing the number of times the wall-hung boiler needs to be ignited, and saving energy.

[0024] In one embodiment, the water pump 8 is a brushless water pump. Brushless water pumps have the characteristics of low noise, high temperature resistance, long life, no maintenance, small size, high efficiency and low power consumption, and are therefore more suitable for use in the heat storage pressurized water tank of a dual-purpose wall-mounted boiler in a flat residential building.

[0025] In one embodiment, for the three-way valve 11, a copper shell is provided at one end of the outlet of the valve body that is perpendicular to the hot water inlet 2 of the wall-hung boiler and the tap water inlet 3. The water flow sensor 17 includes a guide tube disposed in the inner cavity of the copper shell and a magnet disposed on the guide tube. A Hall sensor that cooperates with the guide tube is disposed on the outside of the copper shell. The water flow data detected by the Hall sensor is transmitted to the controller 5. When the controller 5 determines that the owner has used hot water continuously for 25 seconds, the wall-hung boiler water heater 19 is ignited to heat the water. Then, the controller 5 controls the motor on the three-way valve 11. The motor drives the rotating rod, and the rotating rod rotates the valve ball to start the inlet 2, thereby replenishing the water tank with high-temperature hot water from the wall-hung boiler water heater.

[0026] In summary, with the help of the above-mentioned technical solution of the present invention, after installation, the tap water pump 21 is started to inject water and vent air into the inner tank 9 through the tap water inlet 3. After the inner tank 9 is full of water, the power is turned on, and the water temperature in the inner tank 9 is set by the controller 5. The electric heating tube 6 automatically heats the tap water to the set temperature and then automatically stops working. At the same time, the brushless water pump will start working immediately to deliver the hot water in the inner tank 9 to each water point 24. When the owner turns on the hot water tap, constant temperature hot water will flow out immediately. When the homeowner uses water for an extended period or in large quantities, the temperature sensor 29 will automatically identify the real-time water temperature inside the water tank 9, or the water flow sensor 17 will detect how long the homeowner has used hot water and switch the operation of the three-way valve 11 accordingly: When the temperature sensor 29 detects that the actual temperature inside the water tank 9 is 15 degrees lower than the set temperature, the data detected by the temperature sensor 29 is transmitted to the controller 5 to activate the three-way valve 11, opening the hot water inlet 2 of the wall-mounted boiler, allowing the wall-mounted boiler water heater 19 to ignite and replenish the water tank with high-temperature hot water; when the water flow sensor 17 detects that the homeowner has used hot water continuously for 25 seconds, the data detected by the water flow sensor 17 is transmitted to the controller 5 to activate the three-way valve 11, opening the hot water inlet of the wall-mounted boiler, allowing the wall-mounted boiler water heater 19 to ignite and replenish the water tank with high-temperature hot water, at which time the tap water inlet 3 is in the closed state.

[0027] Beneficial effects: 1. Instant hot water: No matter how many water points there are in the house, hot water is available as soon as you turn on the hot water tap.

[0028] 2: Constant water temperature; the water temperature is always maintained at a set temperature.

[0029] 3. It can meet the needs of multiple points of water use at the same time. When two or more water points use water at the same time, the flow rate and temperature remain unchanged.

[0030] 4. Prevent the wall-hung boiler from frequently switching ignition. If hot water is needed for a short time, the wall-hung boiler will not ignite and will continue to supply heating mode. If the water tank temperature is insufficient or the set time is reached, the wall-hung boiler will automatically start to supply domestic hot water.

[0031] 5: The use of a hanging boiler-type pressurized water tank to replace the coil water tank reduces the floor space required and solves the problem of not having enough space to install it in single-story residential homes.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
