Description

Technical Field

[0001] The utility model relates to the technical field of water heater equipment, in particular to a pipeline hot and cold water mixing temperature regulating device. Background Art

[0002] Hot water for washing is a very important part of people's lives, especially in winter, it is indispensable. Hot water is usually heated by gas water heaters or solar water heaters. But when the water outlet is too far from the heat source, such as the distance between the gas furnace and the faucet. When the faucet is turned on, the gas furnace will be ignited to heat the hot water in the water tank, but the faucet can be discharged after it is turned on. At this time, the water discharged from the faucet is the residual water in the pipe, which is cold water, or the gas furnace has not yet heated the water temperature to a certain temperature; and it takes a certain amount of time for hot water to flow into the faucet in use, and the cold water in the water pipe needs to be discharged before the hot water can arrive. This not only causes a lot of water resources to be wasted, but also increases the waiting time of users, which is extremely inconvenient to use. Nowadays, there is an electric heating spray cap used in series with the faucet on the market. It is equipped with an electric heating wire inside, which heats the cold water through the electric heating wire to shorten the waiting time. However, when the device is in use, it cannot achieve precise temperature control; and when the hot water in the water heater arrives, it cannot be turned off immediately, resulting in a waste of electricity.

[0003] To this end, the utility model provides a pipeline hot and cold water mixing temperature adjustment device to improve the temperature control accuracy of heating the water out of the faucet. Utility Model Content

[0027] A plurality of flow guide components are vertically spaced apart in the heating chamber 5, each of the flow guide components comprising a first cone cover 10 and a second cone cover 11, flow guide holes are provided at the axis of the first cone cover 10 and the side of the second cone cover 11, a plurality of electric heating wires 12 are spirally distributed along the conical surface between adjacent first cone covers 10 and second cone covers 11, temperature sensors are provided in the water outlet of the heating chamber 5 and the hot water pipe 9, and the two temperature sensors and the electric heating wires 12 are electrically connected to a controller.

[0028] Principle details of this embodiment:

[0029] A pipeline hot and cold water mixing temperature adjustment device comprises a water tank 1, wherein a heating chamber 5, a mixing chamber 6 and a adjustment chamber 7 are connected from top to bottom in the water tank 1, a mixing device for mixing cold and hot water is provided in the mixing chamber 6, and an adjustment device for adjusting the water inlet amount of a cold water pipe 8 and a hot water pipe 9 is provided in the adjustment chamber; a hot water pipe 9 and a cold water pipe 8 are passed through the bottom wall of the adjustment chamber 7, a regulating valve 3 is provided above the heating chamber 5, a spray cap 2 is provided on the side of the regulating valve 3, and the opening and closing of the spray cap 2 and the regulation of the water output are controlled by the regulating valve 3.

[0030] A plurality of flow guide components are vertically spaced apart in the heating chamber 5, each flow guide component comprises a first cone cover 10 and a second cone cover 11, the axis of the first cone cover 10 and the side of the second cone cover 11 are provided with flow guide holes, and a plurality of electric heating wires 12 are spirally distributed along the cone surface between adjacent first cone covers 10 and second cone covers 11, and a first temperature sensor 15 is provided at the water outlet of the heating chamber 5 for monitoring the final water outlet temperature; a second temperature sensor 16 is provided at the water outlet of the hot water pipe 9 for monitoring the water outlet temperature of the hot water pipe 9. The first temperature sensor 15, the second temperature sensor 16 and the electric heating wire 12 are electrically connected to a controller.

[0031] When in use, first set the water outlet temperature required by the user through the controller in advance; open the regulating valve 3 (pull the valve button 4 upward, the regulating valve 3 is opened, turn it to the right to discharge cold water, and turn it to the left to discharge hot water; in this embodiment, only the hot water outlet is taken as an example), the cold water retained in the hot water pipe 9 first flows into the blending chamber 7 under the action of water pressure, and then enters the mixing chamber 6, and then enters the heating chamber 5, and the cold water is heated by the electric heating wire 12, so that the cold water is heated, the waiting time is shortened, and water resources are saved. A plurality of guide components are arranged in the heating chamber 5. After the water flows into the heating chamber 5, it first gathers toward the center along the first cone cover 10, and sprays out from the guide hole in the center of the first cone cover 10 and impacts the second cone cover 11, so that the water flows along the second cone cover 11 and then floats up from the guide holes on the side of the second cone cover 11 and gathers along the next first cone cover 10 again. An electric heating wire 12 is spirally provided between the adjacent first cone cover 10 and the second cone cover 11. Through such an arrangement, the contact time between the cold water and the electric heating wire 12 is greatly increased, so that after the water flows through the heating chamber 5, its temperature is higher and more, which is more in line with the temperature required by the user, further reducing the flow rate of the empty flow of the water, and saving more water resources.

[0032] When the present embodiment is in use, the final water outlet temperature is monitored in real time by the first temperature sensor 15, and the water outlet temperature of the hot water pipe 9 is monitored in real time by the second temperature sensor 16. When both the water outlet temperature of the heating chamber 5 and the water flow temperature flowing into the water tank 1 from the hot water pipe 9 reach the temperature set by the user, the controller controls the electric heating wire 12 to be turned off, and the electric heating is stopped, so as to achieve precise control of the water flow heating. At this time, the water in the water tank in the hot water boiler can meet the needs of the user, and the electric heating is stopped, which also avoids the waste of electric energy caused by the continuous operation of the electric heating wire 12.

[0033] When the second temperature sensor 16 detects that the temperature of the hot water flowing into the blending chamber 7 from the hot water pipe 9 exceeds the user-set temperature by more than 5°, the regulating device in the blending chamber 7 is started, and the cold water pipe 8 is opened through the regulating device, so that cold water flows into the blending chamber 7 and is mixed in the mixing chamber 6 through the mixing device, and the temperature of the hot water is controlled by blending the cold and hot water; and the higher the temperature of the hot water used in the hot water pipe 9, the greater the opening degree of the cold water pipe 8 and the greater the closing degree of the hot water pipe 9, that is, the more cold water flows in, and the less hot water flows in.

[0034] In this embodiment, multiple groups of guide components are arranged in the heating chamber, thereby increasing the contact time between the water flow and the electric heating wire 12, so that the temperature of the water flow when it is sprayed out is higher, further shortening the waiting time and reducing the waste of water resources; and the first temperature sensor 15 and the second temperature sensor 16 can monitor the water flow temperature in each stage in real time to adjust the opening and closing of the electric heating wire 12 to avoid wasting electric energy; and when the water temperature in the water tank of the gas heating furnace far exceeds the set temperature, the blending chamber 7 can control the blending of cold and hot water, and the higher the temperature, the more cold water flows in and the less hot water flows in, thereby realizing precise control of the temperature.

[0035] In a further embodiment of the present scheme, the mixing device in the mixing bin 6 includes vortex blades 13, and the vortex blades 13 are suspended in the mixing bin 6. When the cold and hot water flow into the mixing bin 6 from the blending bin 7 together, they impact on the vortex blades 13. The vortex blades 13 rotate under the impact of the water flow, thereby stirring and mixing the cold and hot water, so that the cold and hot water are mixed more evenly, so as to improve the precise control of the water temperature; the inner diameter of the connecting part between the mixing bin 6 and the blending bin 7 is smaller than the radius of the blending bin 7, so as to achieve the pressurization when the water flows from the blending bin 7 into the mixing bin 6, thereby increasing the impact force on the vortex blades 13 and ensuring the continuous rotation of the vortex blades 13.

[0036] In a further embodiment of the present scheme, the hot water pipe 9 and the cold water pipe 8 are inserted from the bottom wall of the blending chamber 7 and are flush with the inner bottom wall of the blending chamber 7. The regulating device in the blending chamber 7 includes a fan-shaped sealing plate 14 rotatably mounted on the axis of the inner bottom wall of the blending chamber 7. The sealing plate 14 is driven by a micro motor arranged at the bottom end of the blending chamber 7, and the micro motor is electrically connected to the controller. In the initial state, the sealing plate 14 blocks the outlet of the cold water pipe 8. When the hot water temperature exceeds the standard, the micro motor drives the sealing plate 14 to deflect, so that the cold water pipe 8 is opened and cold water begins to flow in, so as to achieve the blending of hot and cold water.

[0037] In a further embodiment of the present solution, the heating chamber 5, the mixing chamber 6, and the blending chamber 7 are detachably connected via threads, so that the water tank 1 can be disassembled and installed, which is convenient for maintenance, replacement, and regular cleaning of internal components.

[0038] In a further embodiment of the present solution, one-way valves are provided in the connecting ends of the cold water pipe 8, the hot water pipe 9 and the blending bin 7 to prevent water backflow.

[0039] In a further embodiment of the present scheme, the side wall of the water tank 1 is provided with a display screen electrically connected to the controller, and the display screen at least displays a temperature setting button and a digital display, which can display the water temperature in real time, making the temperature viewing more intuitive and convenient.

[0040] In a further embodiment of the present invention, an electric control switch electrically connected to the controller is provided in the water tank 1, and the electric control switch is opened and closed synchronously with the regulating valve 3 to control the opening and closing of the electric heating wire 12. The electric control switch is located at the rear side of the valve button 4 of the regulating valve 3. When the valve button 4 is pulled upward, the rear side of the valve button 4 presses the electric control switch to open the electric heating wire 12, close the regulating valve 3, separate the valve button 4 from the electric control switch, and close the electric heating wire 12, making it more convenient and quick to use.
