Description

Technical Field

[0001] The invention relates to an instantaneous energy-saving hot water auxiliary system, which can improve the convenience during use and reduce the waste of water resources. Background Art

[0002] A water heater is an essential household item that primarily uses energy to heat cold water to a preset temperature and provide hot water of appropriate temperature to users.

[0003] Water heaters can be categorized as gas, electric, and solar based on their heating method. While solar water heaters are a very clean energy source, they are subject to weather constraints. Cloudy days or shorter winter days can affect their heating effectiveness, so gas and electric water heaters remain the mainstream options.

[0004] Figure 1 1 is a schematic diagram of the structure of a conventional water heater. The water heater 10 mainly includes a gas pipeline 11, a heating grate 13 and a delivery pipe 15. The gas pipeline 11 is connected to the heating grate 13 and is used to deliver gas to the heating grate 13.

[0005] The delivery pipe 15 includes an inlet 151 and an outlet 153. Outlet 153 is connected to a faucet 17, and a portion of the delivery pipe 15 is adjacent to the heating grate 13. When the gas burns on the heating grate 13, it heats the water in the adjacent delivery pipe 15. Specifically, cold water enters the delivery pipe 15 through the inlet 151 and is heated by the heating grate 13. The heated water is then delivered to the outlet 153 and provided to the user through the faucet 17.

[0006] If incomplete combustion occurs during the burning of gas by the heating grate 13 of the water heater 10, carbon monoxide will be produced, and carbon monoxide poisoning may occur. Therefore, the water heater 10 is usually installed outdoors or on a balcony to avoid accidents.

[0007] Water heater 10 installed outdoors or on a balcony is usually located some distance from bathroom or kitchen faucets 17 and requires a length of water pipe 14 to connect to the faucet 17. When a user turns on faucet 17, they must wait until the cold water in pipe 14 is drained before hot water is delivered. This waiting time not only inconveniences the user but also wastes water resources. Summary of the Invention

[0008] The object of the present invention is to provide an auxiliary water heater, which mainly includes a conveying pipeline, a temperature sensor, a heating unit and a controller, wherein the controller is connected to the temperature sensor and the heating unit. The conveying pipeline includes a water inlet and a water outlet. The water inlet is connected to a water heater, and the water outlet is connected to a faucet. The temperature sensor is arranged at the water inlet of the conveying pipeline to sense the water temperature entering from the water inlet. Especially in winter, the water temperature is often lower than the normal water temperature. At this time, when the controller determines that the water temperature measured by the temperature sensor is less than a preset temperature, the heating unit will be started to heat the water in the conveying pipeline, so as to quickly deliver hot water to the faucet, eliminating the inconvenience of waiting for hot water in winter and improving the convenience during use. In addition, by using the auxiliary water heater, the waste of water resources can be reduced and the energy efficiency can be improved. This design not only makes the use of hot water respond more quickly, but also increases the comfort and satisfaction of users in the cold season.

[0009] The object of the present invention is to provide a novel instant-heating and energy-saving hot water auxiliary system, which is mainly used to connect in series with a general water heater. The instant-heating and energy-saving hot water auxiliary system is located between the water heater and the faucet. When the user turns on the faucet to use hot water, the instant-heating and energy-saving hot water auxiliary system can be used to heat the water located between the water heater and the instant-heating and energy-saving hot water auxiliary system, and quickly output hot water from the faucet, which is not only beneficial to improving the convenience during use, but also can reduce the waste of water resources.

[0010] The instant-heating and energy-saving hot water auxiliary system described in the present invention mainly includes a conveying pipeline, a temperature sensor, a controller and a heating unit. The temperature sensor is located near the water inlet of the conveying pipeline to sense the water temperature entering the conveying pipeline from the water inlet and transmit the sensed water temperature to the controller. When the controller determines that the water temperature measured by the temperature sensor is lower than a preset temperature, the heating unit will be started to heat the water in the conveying pipeline, so that hot water can be quickly output from the faucet.

[0011] The object of the present invention is to provide an instant-heating and energy-saving hot water auxiliary system, which mainly includes a conveying pipeline, a heating conveying pipeline, a temperature sensor, a controller and a heating unit. The heating conveying pipeline is connected in parallel with a part of the conveying pipeline, and the diameter of the heating conveying pipeline is smaller than that of the conveying pipeline. When the controller determines that the water temperature at the water inlet is lower than the preset temperature, the water will be guided to the heating conveying pipeline, and the heating unit will be started to heat the water in the heating conveying pipeline. Since the diameter and water flow of the heating conveying pipeline are smaller than those of the conveying pipeline, a heating unit with a lower power can be used to heat the water in the heating conveying pipeline, and hot water can be quickly output from the faucet. Therefore, the instant-heating and energy-saving hot water auxiliary system only needs to be connected to a general specification socket for use, which is beneficial to improving the convenience and flexibility of installing and setting the instant-heating and energy-saving hot water auxiliary system. [[ID=!0]] [[ID=!1]]

[0012] In an embodiment of the present invention, the conveying pipeline, the heating conveying pipeline, the temperature sensor and / or the heating unit may be arranged inside a housing, while the controller is located outside the housing. When the instant-heating energy-saving hot water auxiliary system is connected to a socket, the controller is closer to the socket. The controller controls whether to supply the driving power on the socket to the heating unit according to the water temperature measured by the temperature sensor, which is beneficial to improving the flexibility of setting the instant-heating energy-saving hot water auxiliary system.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0040] Figure 2 It is a schematic structural diagram of an embodiment of the instant-heating energy-saving hot water auxiliary system of the present invention. As shown in the figure, the instant-heating energy-saving hot water auxiliary system 20 described in the present invention is mainly used to be connected in series with a water heater 22, and includes a conveying pipeline 21, a temperature sensor 231, a heating unit 25 and a controller 27.

[0041] The conveying pipeline 21 is used to convey water and includes a water inlet 211 and a water outlet 213. The water inlet 211 of the conveying pipeline 21 is used to connect to an outlet 221 of a water heater 22, and the water outlet 213 of the conveying pipeline 21 is used to connect to a faucet 26, such that the instant-heating energy-saving hot water auxiliary system 20 is located between the water heater 22 and the faucet 26. The water heater 22 transmits water to the water inlet 211 of the conveying pipeline 21 and transmits it to the faucet 26 via the water outlet 213 of the conveying pipeline 21. For example, the water inlet 211 of the conveying pipeline 21 can be connected to the outlet 221 of the water heater 22 through a water pipe 24. The distance between the instant-heating energy-saving hot water auxiliary system 20 and the faucet 26 is less than or much less than the distance between the instant-heating energy-saving hot water auxiliary system 20 and the water heater 22.

[0042] When the user turns on the faucet 26, the flowing water flow will trigger the water heater 22 to start and heat. The heated water is output from the outlet 221 of the water heater 22 and pushes the water originally in the water pipe 24, such that the water in the water pipe 24 is conveyed to the water inlet 211 of the conveying pipeline 21 and the faucet 26.

[0043] The temperature sensor 231 is arranged near the water inlet 211 of the conveying pipeline 21 and is used to sense the temperature of the water entering through the water inlet 211. For example, the temperature sensor 231 can be a thermometer. The heating unit 25 is connected to the conveying pipeline 21 or adjacent to a part of the conveying pipeline 21 and is used to heat the water in the conveying pipeline 21. For example, the heating unit 25 can be an electric heating pipe, an induction coil, etc. When the heating unit 25 is an electric heating pipe, the heating unit 25 can directly contact the conveying pipeline 21 or be arranged inside the conveying pipeline 21.

[0044] The controller 27 is electrically connected to the temperature sensor 231 and the heating unit 25 and is used to receive the water temperature measured by the temperature sensor 231 and to control 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 according to the water temperature measured by the temperature sensor 231, or adjust the heating power of the heating unit 25. In actual application, the controller 27 may include a control circuit 271 and a power supply 273. The control circuit 271 is used to receive the water temperature measured by the temperature sensor 231 and control whether the power supply 273 provides a driving power supply 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 the transformer is connected to the heating unit 25, and the other side is connected to an external driving power supply via the switching unit, and the control circuit 271 can control the opening or closing of the switching unit to start or stop the heating unit 25.

[0045] In an embodiment of the present invention, the controller 27 can set a preset temperature, for example, 40 degrees Celsius. When the controller 27 receives that the water temperature measured by the temperature sensor 231 is lower than the preset temperature, it will activate the heating unit 25 and heat the water in the conveying pipeline 21 through the heating unit 25.

[0046] Conversely, when the controller 27 receives that the water temperature measured by the temperature sensor 231 is higher than 40 degrees, it will turn off the heating unit 25, so that the heating unit 25 does not heat the water in the conveying pipeline 21.

[0047] As described in the prior art, when the user turns on the faucet 26 to use hot water, it is necessary to wait until all the cold water in the water pipe 24 between the faucet 26 and the water heater 22 flows out of the faucet 26 before the hot water heated by the water heater 22 can flow out of the faucet 26. In this way, not only will it affect the convenience during use, but it will also cause waste of water resources invisibly.

[0048] For this reason, the present invention provides an instant heating and energy-saving hot water auxiliary system 20. The instant heating and energy-saving hot water auxiliary system 20 is closer to the faucet 26. When the user turns on the faucet 26, the instant heating and energy-saving hot water auxiliary system 20 can be used to heat the cold water in the water pipe 24, for example, heat the cold water between the instant heating and energy-saving hot water auxiliary system 20 and the water heater 22, and immediately output hot water from the faucet 26. In addition, before the water heater 22 completes warm-up, heating can also be carried out through the instant heating and energy-saving hot water auxiliary system 20. Through the instant heating and energy-saving hot water auxiliary system 20 described in the present invention, not only can hot water be quickly provided to the user to improve the convenience during use, but it can also reduce waste of water resources.

[0049] In an embodiment of the present invention, the instant heating and energy-saving hot water auxiliary system 20 may include a water flow detector 233, where the water flow detector 233 is connected to the conveying pipeline 21 and the controller 27. The water flow detector 233 is used to detect the water flow in the conveying pipeline 21 and transmit the measured water flow to the controller 27. For example, the position of the water flow detector 233 is closer to the water inlet 211 of the conveying pipeline 21. When the controller 27 receives that the water flow detected by the water flow detector 233 is greater than a preset flow rate, the controller 27 will activate the heating unit 25 and heat the water in the conveying pipeline 21 through the heating unit 25.

[0050] Specifically, the water flow detector 233 can be a protection device for the instant heating and energy-saving hot water auxiliary system 20. When there is no water in the conveying pipeline 21 or the water in the conveying pipeline 21 does not flow, the controller 27 will not start the heating unit 25 for heating to prevent dry burning of the instant heating and energy-saving hot water auxiliary system 20 and improve the safety of use.

[0051] In another embodiment of the present invention, as Figure 3As shown, the instant-heating energy-saving hot water auxiliary system 20 may include a regulating valve 29, where the regulating valve 29 is connected to the delivery pipeline 21 and the controller 27. The regulating valve 29 is disposed on the delivery pipeline 21 and near the water inlet 211 of the delivery pipeline 21. The controller 27 can be used to control the regulating valve 29 and adjust the water flow rate entering the delivery pipeline 21 from the water inlet 211.

[0052] In actual application, when the controller 27 determines that the water temperature measured by the temperature sensor 231 is lower than the preset temperature, the controller 27 will lower the regulating valve 29 to reduce the water flow rate entering the delivery pipeline 21 from the water inlet 211 via the regulating valve 29. Since the water flow rate in the delivery pipeline 21 is small, a heating unit 25 with a lower power can be selected to be installed in the instant-heating energy-saving hot water auxiliary system 20 to improve the convenience of installation and the safety of use of the instant-heating energy-saving hot water auxiliary system 20. For example, the instant-heating energy-saving hot water auxiliary system 20 only needs to be connected to a general-specification socket, and the water with a small flow rate in the delivery pipeline 21 can be heated by the heating unit 25, without the need to connect the instant-heating energy-saving hot water auxiliary system 20 to a special-specification socket.

[0053] In an embodiment of the present invention, the instant-heating energy-saving hot water auxiliary system 20 may include a housing 28, where the delivery pipeline 21, the temperature sensor 231, the heating unit 25, and the controller 27 can be disposed in the housing 28, and the above-mentioned components are protected by the housing 28. In different embodiments, the housing 28 can be used to cover the delivery pipeline 21, the temperature sensor 231, and the heating unit 25, while the controller 27 is disposed outside the housing 28. For example, the controller 27 can be disposed on the plug of the instant-heating energy-saving hot water auxiliary system 20 and connected to the heating unit 25 through a switching unit.

[0054] Specifically, when the water temperature received by the controller 27 from the temperature sensor 231 is less than the preset temperature, the controller 27 will activate the switching unit, so that the socket provides a driving power supply to the heating unit 25. On the contrary, when the water temperature received by the controller 27 from the temperature sensor 231 is greater than the preset temperature, the controller 27 will deactivate the switching unit, so that the socket does not provide a driving power supply to the heating unit 25.

[0055] As Figure 4 shown, it is a schematic structural diagram of another embodiment of the instant-heating energy-saving hot water auxiliary system of the present invention. As shown in the figure, the instant-heating energy-saving hot water auxiliary system 30 of the present invention is mainly used to be connected in series with a water heater 22, and includes a delivery pipeline 21, a heating delivery pipeline 31, a temperature sensor 231, a heating unit 25, and a controller 27, where the diameter of the heating delivery pipeline 31 is smaller than that of the delivery pipeline 21.

[0056] The water inlet 211 of the conveying pipeline 21 is used to connect to the outlet 221 of the water heater 22, and the water outlet 213 of the conveying pipeline 21 is used to connect to the faucet 26. In practical applications, the distance between the instant heating and energy-saving hot water auxiliary system 30 and the faucet 26 is less than or much less than the distance between the instant heating and energy-saving hot water auxiliary system 30 and the water heater 22.

[0057] The heating conveying pipeline 31 is connected in parallel with a part of the conveying pipeline 21. The heating conveying pipeline 31 may include a first connection end 311 and a second connection end 313, and is connected to the conveying pipeline 21 through 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 closer to the water inlet 211 of the conveying pipeline 21, and the second connection end 313 of the heating conveying pipeline 31 is closer to the water outlet 213 of the conveying pipeline 21.

[0058] The instant heating and energy-saving hot water auxiliary system 30 further includes a valve 391. The valve 391 is connected to the conveying pipeline 21. For example, the valve 391 is closer to the water inlet 211, and can control whether the water entering from the water inlet 211 enters the conveying pipeline 21 and is transmitted to the water outlet 213 through the conveying pipeline 21 by opening or closing the valve 391.

[0059] The heating unit 25 is connected to the heating conveying pipeline 31 or adjacent to a part of the heating conveying pipeline 31, and is used to heat the water in the heating conveying pipeline 31.

[0060] The controller 27 is electrically connected to the temperature sensor 231, the heating unit 25 and the valve 391. The controller 27 can receive the measured water temperature from the temperature sensor 231, and turn on or off the heating unit 25 and the valve 391 according to the water temperature.

[0061] Specifically, the controller 27 can set a preset temperature, for example, 40 degrees Celsius. When the controller 27 receives that the water temperature measured by the temperature sensor 231 is lower than 40 degrees, the valve 391 will be closed, so that the water entering from the water inlet 211 will not enter the conveying pipeline 21, but is conveyed to the water outlet 213 through the heating conveying pipeline 31. In addition, the controller 27 will start the heating unit 25 and heat the water in the heating conveying pipeline 31 through the heating unit 25 to increase the water temperature.

[0062] The diameter of the heated water delivery pipeline 31 is smaller than that of the water delivery pipeline 21, and the water flow rate in the heated water delivery pipeline 31 is less than that in the water delivery pipeline 21. Therefore, the instant-heating energy-saving hot water auxiliary system 30 can select a heating unit 25 with a relatively small installation power, which is sufficient to heat the water in the heated water delivery pipeline 31. In this way, the flexibility and convenience of installing and using the instant-heating energy-saving hot water auxiliary system 30 can be improved. For example, the instant-heating energy-saving hot water auxiliary system 30 only needs to be connected to a general-specification socket, rather than a special-specification socket.

[0063] Changing to use the heated water delivery pipeline 31 with a smaller diameter to transport water will reduce the water flow rate flowing out of the faucet 26. In practical applications, a heated water delivery pipeline 31 with an appropriate size can be selected to reduce the great impact on the convenience of use for users.

[0064] When the controller 27 receives that the water temperature measured by the temperature sensor 231 is higher than the preset temperature, such as 40 degrees, it will open the valve 391 and close the heating unit 25, so that the water entering from the water inlet 211 flows through the water delivery pipeline 21 and / or the heated water delivery pipeline 31 to the water outlet 213, and the water flow rate flowing out of the faucet 26 will increase. In an embodiment of the present invention, another valve can also be provided on the heated water delivery pipeline 31, and the opening or closing of the valve on the heated water delivery pipeline 31 is opposite to that of the valve 391 on the water delivery pipeline 21.

[0065] Through the instant-heating energy-saving hot water auxiliary system 30 described in the present invention, not only can hot water be quickly provided to users to improve the convenience during use, but also the waste of water resources can be reduced.

[0066] In an embodiment of the present invention, the instant-heating energy-saving hot water auxiliary system 30 may include a housing 28, and the water delivery pipeline 21, the heated water delivery pipeline 31, the temperature sensor 231, the heating unit 25 and the controller 27 can be arranged inside the housing 28. In different embodiments, the housing 28 is used to cover the water delivery pipeline 21, the heated water delivery pipeline 31, the temperature sensor 231 and the heating unit 25, and the controller 27 can be arranged outside the housing 28. For example, the controller 27 can be arranged on the plug of the instant-heating energy-saving hot water auxiliary system 30.

[0067] The above is only a preferred embodiment of the present invention, and is not used to limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made according to the shape, structure, features and spirit described in the present invention should be included within the protection scope of the present invention.
