Description

[Technical Field]

[0001] The present invention relates to an instantaneous energy-saving auxiliary hot water system, which is convenient to use and reduces the waste of water resources. [Background technology]

[0002] 2. Description of the Related Art A water heater is an essential household appliance, and is mainly used to heat cold water to a predetermined temperature using energy and provide hot water at an appropriate temperature to users.

[0003] Depending on the energy heating method, water heaters can be divided into gas water heaters, electric water heaters, and solar water heaters. Solar water heaters are clean energy sources, but are limited by the weather, and the heating effect of solar water heaters is affected during cloudy days and the short sunshine hours in winter, so gas water heaters and electric water heaters are currently the mainstream products.

[0004] FIG. 1 is a structural schematic diagram of a known water heater, in which the water heater 10 mainly comprises a combustion gas pipe 11, a heating burner 13, and a conveying pipe 15, and the combustion gas pipe 11 is connected to the heating burner 13 to convey the combustion gas to the heating burner 13.

[0005] The conveying pipes 15 have an inlet 151 and an outlet 153, and the outlet 153 is connected to a faucet 17, while some of the conveying pipes 15 are adjacent to the heating burner 13. When combustion gas is burned in the heating burner 13, it heats the water in the adjacent conveying pipe 15. Specifically, cold water enters the conveying pipe 15 from the inlet 151 and is heated by the heating burner 13 in the conveying pipe 15, and the heated hot water is conveyed to the outlet 153 and provided to the user from the faucet 17.

[0006] If the heating burner 13 of the water heater 10 is incomplete in the combustion process of the combustion gas, it may generate carbon monoxide, which may result in carbon monoxide poisoning. Therefore, the water heater 10 is usually installed outdoors or on a balcony to prevent unexpected accidents. Summary of the Invention [Problem to be solved by the invention]

[0007] A water heater 10 installed outdoors or on a balcony is usually located a certain distance from a bathroom or kitchen faucet 17 and must be connected to the bathroom or kitchen faucet 17 by a certain length of hose 14. When a user opens the faucet 17, the faucet 17 can only deliver hot water after the cold water in the hose 14 has been drained and emptied. This certain waiting time not only causes inconvenience to the user but also unintentionally wastes water resources. [Means for solving the problem]

[0008] The present invention provides an auxiliary water heater, mainly comprising a conveying pipeline, a temperature sensor, a heating unit, and a controller, the controller being connected to the temperature sensor and the heating unit. The conveying pipeline includes a water intake and a drain, the water intake being connected to the water heater, and the drain being connected to a faucet. The temperature sensor is installed at the water intake of the conveying pipeline to detect the temperature of the water entering through the water intake. In particular, in winter, the water temperature often drops below normal. When the controller determines that the water temperature measured by the temperature sensor is lower than a predetermined temperature, it activates the heating unit, which heats the water in the conveying pipeline and quickly delivers hot water to the faucet, eliminating the inconvenience of waiting for hot water during winter and improving user convenience. Furthermore, the use of an auxiliary water heater can reduce water waste and increase energy efficiency. This design not only ensures rapid response to hot water usage, but also enhances user comfort and satisfaction during cold seasons.

[0009] This invention proposes a new type of instantaneous energy-saving hot water auxiliary system, which is mainly intended for connection in series with a conventional water heater. The instantaneous energy-saving hot water auxiliary system is located between the water heater and the faucet. When a user opens the faucet to use hot water, the instantaneous energy-saving hot water auxiliary system heats the water located between the water heater and the instantaneous energy-saving hot water auxiliary system, and then the hot water can be quickly delivered from the faucet. This not only improves user convenience but also reduces water waste.

[0010] The instantaneous energy-saving hot water auxiliary system described in this invention mainly includes a conveying pipeline, a temperature sensor, a controller, and a heating unit. The temperature sensor is located near the water intake of the conveying pipeline to detect the temperature of the water entering the conveying pipeline from the water intake and transmit the detected water temperature to the controller. When the controller determines that the water temperature measured by the temperature sensor is lower than a predetermined temperature, it activates the heating unit to heat the water in the conveying pipeline so that the faucet can quickly deliver hot water.

[0011] The present invention provides an instantaneous energy-saving auxiliary hot water system, mainly comprising a conveying pipeline, a heating conveying pipeline, a temperature sensor, a controller, and a heating unit. The heating conveying pipeline is connected in parallel to some of the conveying pipelines, and the diameter of the heating conveying pipeline is smaller than that of the conveying pipelines. When the controller determines that the water temperature at the water intake is lower than a predetermined temperature, it guides water into the heating conveying pipeline and activates the heating unit to heat the water in the heating conveying pipeline. Because the diameter and water flow rate of the heating conveying pipeline are smaller than those of the conveying pipeline, a lower-power heating unit can be used to heat the water in the heating conveying pipeline, allowing hot water to be quickly delivered from the faucet. Therefore, the instantaneous energy-saving auxiliary hot water system can be used simply by connecting a standard socket, which is advantageous in increasing the convenience and flexibility of installation and configuration of the instantaneous energy-saving auxiliary hot water system.

[0012] In an embodiment of the present invention, the conveying pipe, the heating conveying pipe, the temperature sensor, and / or the heating unit can be installed in a normal case, while the controller is located outside the case. When the instantaneous energy-saving hot water auxiliary system is connected to a socket, the controller is located near the socket, and the controller controls whether to supply the socket's driving power to the heating unit according to the water temperature measured by the temperature sensor, which is advantageous in increasing the installation flexibility of the instantaneous energy-saving hot water auxiliary system.

[0013] In order to achieve the above-mentioned object, the present invention provides an instantaneous energy-saving auxiliary hot water system, comprising: a conveying pipeline having a water intake for connecting a water heater and a drain for connecting a faucet; a temperature sensor located close to the water intake of the conveying pipeline for detecting the temperature of water entering the conveying pipeline from the water intake; a heating unit connected to the conveying pipeline or adjacent to a part of the conveying pipeline for heating the water in the conveying pipeline; a controller electrically connected to the temperature sensor and the heating unit for receiving the water temperature measured by the temperature sensor and for controlling whether the heating unit heats the water in the conveying pipeline; and a water heater that sends water to the water intake of the conveying pipeline and also sends it from the drain of the conveying pipeline to the faucet; and when the water temperature measured by the temperature sensor received by the controller is lower than a predetermined temperature, the heating unit is activated to heat the water in the conveying pipeline.

[0014] The present invention provides another instantaneous energy-saving hot water auxiliary system, which includes a conveying pipeline having a water intake for connecting a water heater and a drain for connecting a faucet; a heating conveying pipeline connected in parallel to a part of the conveying pipeline and having a smaller pipe diameter than the conveying pipeline; a temperature sensor located close to the water intake of the conveying pipeline and for detecting the temperature of water entering the conveying pipeline from the water intake; a heating unit connected to the conveying pipeline or adjacent to a part of the conveying pipeline and for heating the water in the conveying pipeline; a valve connected to the conveying pipeline and for controlling whether the water entering from the water intake is sent from the conveying pipeline to the drain; and a temperature sensor. The water heater comprises a heating unit and a controller electrically connected to the valve for receiving the water temperature measured by the temperature sensor, for controlling whether the heating unit heats the water in the heating conveying pipeline, and for controlling the opening or closing of the valve. The water heater sends water to the water intake of the conveying pipeline and from the outlet of the conveying pipeline to the faucet. When the water temperature measured by the temperature sensor received by the controller is lower than a predetermined temperature, the valve is closed and the water entering from the water intake is conveyed from the heating conveying pipeline to the outlet, and the heating unit is activated to heat the water in the conveying pipeline.

[0015] In at least one embodiment of the instantaneous energy-saving hot water auxiliary system of the present invention, a water flow sensor is provided adjacent to the water intake of the conveying pipeline and connected to the controller, the water flow sensor is for measuring the water flow rate entering the conveying pipeline from the water intake and transmitting the measured water flow rate to the controller.

[Figure 2] FIG. 2 is a structural schematic diagram of an embodiment of the instantaneous energy-saving auxiliary hot water system of the present invention. [Figure 3] FIG. 3 is a structural schematic diagram of another embodiment of the instantaneous energy-saving auxiliary hot water system of the present invention. [Figure 4] FIG. 4 is a structural schematic diagram of another embodiment of the instantaneous energy-saving auxiliary hot water system of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0023] 2 is a structural schematic diagram of an embodiment of the instantaneous energy-saving auxiliary hot water system of the present invention. As shown in the figure, the instantaneous energy-saving auxiliary hot water system 20 described in the present invention is mainly for connecting water heaters 22 in series, and includes a conveying pipeline 21, a temperature sensor 231, a heating unit 25, and a controller 27.

[0024] The conveying pipeline 21 is for conveying water and includes a water intake 211 and a drain 213. The water intake 211 of the conveying pipeline 21 is connected to an outlet 221 of a water heater 22, while the drain 213 of the conveying pipeline 21 is connected to a faucet 26, so that the instantaneous energy-saving hot water auxiliary system 20 is located between the water heater 22 and the faucet 26. The water heater 22 delivers water to the water intake 211 of the conveying pipeline 21 and from the drain 213 of the conveying pipeline 21 to the faucet 26. For example, the water intake 211 of the conveying pipeline 21 can be connected to the outlet 221 of the water heater 22 via a hose 24, and the distance between the instantaneous energy-saving hot water auxiliary system 20 and the faucet 26 is smaller or much smaller than the distance between the instantaneous energy-saving hot water auxiliary system 20 and the water heater 22.

[0025] When a user opens the faucet 26, the flowing water triggers the activation of the water heater 22 to heat the water. The heated water is sent out from the outlet 221 of the water heater 22, pushing out the water that was originally in the hose 24, so that the water in the hose 24 is transported to the water intake 211 of the transport pipeline 21 and the faucet 26.

[0026] The temperature sensor 231 is provided near the water intake 211 of the conveying pipeline 21 to sense the temperature of the water entering from the water intake 211; for example, the temperature sensor 231 may be a thermometer. The heating unit 25 is connected to the conveying pipeline 21 or adjacent to a portion of the conveying pipeline 21 to heat the water in the conveying pipeline 21; for example, the heating unit 25 may be an electric heating tube, an induction coil, etc. If the heating unit 25 is an electric heating tube, the heating unit 25 may be in direct contact with the conveying pipeline 21 or may be provided inside the conveying pipeline 21.

[0027] The controller 27 is electrically connected to the temperature sensor 231 and the heating unit 25, and is for receiving the water temperature measured by the temperature sensor 231 and for controlling whether the heating unit 25 heats the water in the conveying pipeline 21. The controller 27 can control whether the heating unit 25 heats the water in the conveying pipeline 21 or adjust the heating output of the heating unit 25 according to the water temperature measured by the temperature sensor 231. In actual use, the controller 27 may include a control circuit 271 and a power supply 273, and the control circuit 271 receives the water temperature measured by the temperature sensor 231 and controls whether the power supply 273 provides driving power to the heating unit 25 according to the measured water temperature. In an embodiment of the present invention, the power supply 273 may include a transformer and / or a switching unit, one side of which is connected to the heating unit 25 and the other side of which is connected to an external driving power source by the switching unit, while the control circuit 271 can start or stop the heating unit 25 by controlling the on or off of the switching unit.

[0028] In an embodiment of the present invention, a predetermined temperature can be set in the controller 27, for example, 40 degrees Celsius. If the water temperature measured by the temperature sensor 231 received by the controller 27 is lower than the predetermined temperature, the heating unit 25 is activated and the heating unit 25 heats the water in the conveying pipeline 21.

[0029] Conversely, if the water temperature measured by the temperature sensor 231 received by the controller 27 is higher than 40 degrees, the heating unit 25 is stopped so that the heating unit 25 does not heat the water in the transport pipeline 21.

[0030] As described in the background art, when a user opens the faucet 26 to use hot water, the hot water heated by the water heater 22 cannot flow out of the faucet 26 until the cold water in the hose 24 between the faucet 26 and the water heater 22 has completely flowed out of the faucet 26. This not only affects convenience during use, but also leads to unintentional waste of water resources.

[0031] For this reason, the present invention provides an instantaneous energy-saving auxiliary hot water system 20, which is located near a faucet 26. When a user opens the faucet 26, the instantaneous energy-saving auxiliary hot water system 20 may heat the water in a hose 24, for example, by heating the cold water located between the instantaneous energy-saving auxiliary hot water system 20 and a water heater 22, and then instantly supplying hot water from the faucet 26. In addition, the instantaneous energy-saving auxiliary hot water system 20 may also heat the water until the water heater 22 has finished warming up. The instantaneous energy-saving auxiliary hot water system 20 described in the present invention not only provides users with hot water quickly, improving convenience during use, but also reducing waste of water resources.

[0032] In an embodiment of the present invention, the instantaneous energy-saving hot water auxiliary system 20 may include a water quantity sensor 233, which is connected to the conveying pipeline 21 and the controller 27. The water quantity sensor 233 detects the water flow rate in the conveying pipeline 21 and transmits the measured water flow rate to the controller 27. For example, the water quantity sensor 233 is located close to the water intake 211 of the conveying pipeline 21, and the controller 27 activates the heating unit 25 to heat the water in the conveying pipeline 21 only when the water flow rate detected by the water quantity sensor 233 and received by the controller 27 is greater than a predetermined flow rate.

[0033] Specifically, the water volume sensor 233 may be a protection device for the instantaneous energy-saving hot water auxiliary system 20, and when there is no water in the conveying pipeline 21 or when the water in the conveying pipeline 21 is not flowing, the controller 27 will not start the heating unit 25 to heat, thereby preventing the instantaneous energy-saving hot water auxiliary system 20 from running dry and improving safety in use.

[0034] 3 , the instant energy-saving hot water auxiliary system 20 may include a regulating valve 29, which is connected to the conveying pipeline 21 and a controller 27. The regulating valve 29 is provided in the conveying pipeline 21 and is adjacent to a water intake 211 of the conveying pipeline 21. The controller 27 may be configured to control the regulating valve 29 to regulate the flow rate of water entering the conveying pipeline 21 from the water intake 211.

[0035] In actual use, when controller 27 determines that the water temperature measured by temperature sensor 231 is lower than a predetermined temperature, controller 27 adjusts regulating valve 29 downward, thereby reducing the flow rate of water entering water intake 21 from water intake 211 through regulating valve 29 into conveying pipeline 21. Because the water flow rate in conveying pipeline 21 is small, a low-output heating unit 25 can be selected to be installed in instantaneous energy-saving auxiliary hot water system 20, thereby improving the ease of installation and safety of use of instantaneous energy-saving auxiliary hot water system 20. For example, instantaneous energy-saving auxiliary hot water system 20 can heat the water in conveying pipeline 21, which has a low water flow rate, by simply connecting it to a standard socket, and there is no need to connect instantaneous energy-saving auxiliary hot water system 20 to a special socket.

[0036] In an embodiment of the present invention, the instantaneous energy-saving hot water auxiliary system 20 may include a conventional case 28, in which the conveying pipe 21, the temperature sensor 231, the heating unit 25, and the controller 27 are disposed, and the case 28 protects the above-mentioned elements. In another embodiment, the case 28 may be configured to cover the conveying pipe 21, the temperature sensor 231, and the heating unit 25, while the controller 27 is disposed outside the case 28. For example, the controller 27 may be disposed on a plug of the instantaneous energy-saving hot water auxiliary system 20 and connected to the heating unit 25 by a switching unit.

[0037] Specifically, if the water temperature received by the temperature sensor 231 of the controller 27 is lower than a predetermined temperature, the controller 27 turns on the switching unit to provide driving power to the heating unit 25 via the socket. Conversely, if the water temperature received by the temperature sensor 231 of the controller 27 is higher than the predetermined temperature, the controller 27 turns off the switching unit to prevent driving power from being provided to the heating unit 25 via the socket.

[0038] 4 is a structural schematic diagram of another embodiment of the instantaneous energy-saving hot water auxiliary system of the present invention. As shown in the figure, the instantaneous energy-saving hot water auxiliary system 30 described in the present invention is mainly for connecting water heaters 22 in series, and includes a conveying pipe 21, a heating conveying pipe 31, a temperature sensor 231, a heating unit 25, and a controller 27, and the diameter of the heating conveying pipe 31 is smaller than that of the conveying pipe 21.

[0039] The water intake 211 of the conveying pipeline 21 is for connecting the outlet 221 of the water heater 22, while the outlet 213 of the conveying pipeline 21 is for connecting the faucet 26. In actual use, the distance between the instantaneous energy-saving hot water auxiliary system 20 and the faucet 26 is smaller or much smaller than the distance between the instantaneous energy-saving hot water auxiliary system 20 and the water heater 22.

[0040] The heating conveying pipeline 31 is connected in parallel to some of the conveying pipelines 21, and the heating conveying pipeline 31 has a first connection end 311 and a second connection end 313, and is connected to the conveying pipeline 21 by the first connection end 311 and the second connection end 313. For example, the first connection end 311 of the heating conveying pipeline 31 is close to the water intake 211 of the conveying pipeline 21, while the second connection end 313 of the heating conveying pipeline 31 is close to the discharge outlet 213 of the conveying pipeline 21.

[0041] The instantaneous energy-saving hot water auxiliary system 30 further includes a valve 391, which is connected to the conveying pipeline 21. For example, the valve 391 is located close to the water intake 211. By opening or closing the valve 391, it is possible to control whether the water entering from the water intake 211 enters the conveying pipeline 21 and is sent from the conveying pipeline 21 to the drain outlet 213.

[0042] The heating unit 25 is connected to the heating and conveying pipeline 31 or is adjacent to a part of the heating and conveying pipeline 31, and serves to heat the water in the heating and conveying pipeline 31.

[0043] The controller 27 is electrically connected to the temperature sensor 231, the heating unit 25, and the valve 391, and the controller 27 receives the measured water temperature from the temperature sensor 231 and can start or stop the heating unit 25 and open or close the valve 391 based on the water temperature.

[0044] Specifically, a predetermined temperature can be set in the controller 27, for example, 40 degrees Celsius, and when the water temperature measured by the temperature sensor 231 received by the controller 27 is lower than 40 degrees, the controller 27 closes the valve 391 to prevent the water entering from the water intake 211 from entering the transport pipeline 21, and transports the water from the heated transport pipeline 31 to the drain 213. In addition, the controller 27 activates the heating unit 25 to heat the water in the heated transport pipeline 31 with the heating unit 25, thereby increasing the temperature of the water.

[0045] Because the diameter of the heating and transporting pipeline 31 is smaller than that of the transporting pipeline 21 and the water flow rate in the heating and transporting pipeline 31 is smaller than that in the transporting pipeline 21, the instantaneous energy-saving auxiliary hot water system 30 can choose to install a heating unit 25 with a low output to sufficiently heat the water in the heating and transporting pipeline 31. In this way, the installation and use of the instantaneous energy-saving auxiliary hot water system 30 can be made more flexible and convenient; for example, the instantaneous energy-saving auxiliary hot water system 30 only needs to be connected to a standard socket, and no special socket is required.

[0046] Although the flow rate of water flowing out of the faucet 26 decreases, the water is conveyed by changing to a heating conveying pipeline 31 with a smaller pipe diameter. In actual use, selecting a heating conveying pipeline 31 of an appropriate size can reduce excessive impact on the user's convenience.

[0047] If the water temperature measured by the temperature sensor 231 received by the controller 27 is higher than a predetermined temperature, for example, 40 degrees, the valve 391 is opened, the heating unit 25 is stopped, and the water entering from the water intake 211 flows through the conveying pipeline 21 and / or the heated conveying pipeline 31 to the drain 213, while the flow rate of water sent out from the faucet 26 increases. In an embodiment of the present invention, other valves may also be provided in the heated conveying pipeline 31, and the opening and closing of the valve of the heated conveying pipeline 31 is opposite to that of the valve 391 of the conveying pipeline 21.

[0048] The instant energy-saving auxiliary hot water system 30 according to the present invention can quickly provide hot water to users, which not only increases convenience during use but also reduces the waste of water resources.

[0049] In an embodiment of the present invention, the instantaneous energy-saving hot water auxiliary system 20 may include a normal case 28, and the conveying pipe 21, the heated conveying pipe 31, the temperature sensor 231, the heating unit 25, and the controller 27 may be disposed within the case 28. In another embodiment, the case 28 is for covering the conveying pipe 31, the temperature sensor 231, and the heating unit 25, while the controller 27 may be disposed outside the case 28, for example, the controller 27 may be disposed in a plug of the instantaneous energy-saving hot water auxiliary system 20.

[0050] The above-described embodiments are merely preferred embodiments of the present invention and do not limit the scope of the present invention. All equivalent changes and modifications based on the shape, structure, features, and spirit of the present invention are intended to be included in the scope of the claims of the present invention.
