Description

Intelligent constant temperature water outlet control device and method

Technical Field

The present invention relates to the field of kitchen and bathroom water supply regulating equipment, and in particular to an intelligent constant temperature water outlet regulating device and method.

Background technique

In modern kitchens and bathrooms, small proximal water heaters such as small kitchen boilers are often used as proximal hot water sources, and large distal water heaters or HVAC water supply are used as distal hot water sources. The design combines proximal and distal hot water sources to meet the different hot water usage requirements in different areas such as kitchens, bathrooms, balconies, and laundry rooms.

At present, there are no water heaters with hot water circulation in the market. When using hot water, it is necessary to drain the cold water from the outlet of the water heater to the water-using end first, which is extremely wasteful of water resources and energy. Zero cold water water heater products with circulating pipes need to continuously heat the hot water in the pipes to continuously provide hot water at the water-using end. Even if the hot water in the pipes is circulated regularly, in the non-scheduled stage, the hot water will gradually cool down to cold water when it stays in the pipes, causing energy waste, and it is impossible to enjoy zero cold water when it is used in the non-scheduled stage. Using a small kitchen treasure alone to supply water, it is impossible to use more economical hot water such as gas, solar energy, heat pump, etc. at a distance, and the water storage type small kitchen treasure can only provide about 1-2 minutes of hot water. The power of the instant small kitchen treasure reaches 7kW to provide sufficient hot water in winter. However, the power of 7kW exceeds that of ordinary household sockets (normal socket load 3.2kW) and the load of civil electricity meters. And most small kitchen treasures do not provide constant temperature function.

An intelligent constant temperature water outlet control device, which is arranged on a pipeline between a near-end hot water source, a far-end hot water source and a water tap, and comprises a cold water solenoid valve, a far-end hot water valve, a constant temperature valve group and a timing controller;

The water inlet end of the cold water solenoid valve is connected to external cold water, the remote hot water valve is connected to the water outlet pipeline of the remote hot water source, the water outlet end of the cold water solenoid valve and the water outlet end of the remote hot water valve are connected to the water inlet end of the proximal hot water source through a three-way pipe, the hot water end of the thermostatic valve group is connected to the water outlet end of the proximal hot water source, and the cold water end is connected to external cold water, and the hot water outlet end of the thermostatic valve group is connected to the water tap;

The timing controller is electrically connected to the cold water solenoid valve to control the cold water solenoid valve to close after the timing ends.

In order to solve the above technical problems, another technical solution adopted by the present invention is:

An intelligent constant temperature water outlet control method, using the above-mentioned intelligent constant temperature water outlet control device, comprises the following steps:

Presetting the timing time of the timing controller;

When constant temperature hot water is needed, the required outlet water temperature is set by adjusting the thermostatic valve group, and the user determines whether to use the hot water from the remote hot water source according to the needs; if so, the water tap is continuously opened, closed and opened again within the first preset time, the cold water solenoid valve is switched to a closed state or kept in a normally closed state within the second preset time, the remote hot water valve is switched to an open state, and the remote hot water source delivers hot water to the near-end hot water source; if not, the water tap is opened, and the timing controller is started to start timing, the near-end hot water source supplies hot water to the thermostatic valve group, the thermostatic valve group mixes the external cold water and the incoming hot water to adjust the water temperature and delivers it to the water tap; when the timing of the timing controller reaches the third preset time, the user determines whether to continue to use the hot water from the near-end hot water source according to the needs, and if so, the timing of the timing controller is restarted by closing the water tap and restarting the timing of the timing controller, and the timing controller controls the cold water solenoid valve to remain in an open state; if not, the timing controller controls the cold water solenoid valve to switch to a closed state, the remote hot water valve is switched to an open state, and the remote hot water source delivers hot water to the near-end hot water source.

The beneficial effects of the present invention are as follows: the control device is connected to the water outlet pipes of the proximal hot water source and the distal hot water source, and when the hot water consumption is small, the proximal hot water can be directly used for temperature adjustment to provide constant temperature hot water; when the proximal hot water storage is less than the hot water consumption, the distal hot water is intelligently controlled to be replenished before the proximal hot water is exhausted, so that the outlet water always maintains a constant temperature, and constant temperature hot water is provided without waiting for the cold water in the distal hot water outlet pipe to be released, and the hot water circulation pipe and hot water circulation loss are reduced, thus saving energy and being more convenient and quick to use.

From the above description, it can be seen that the beneficial effect of the present invention is that the control device is connected to the outlet pipes of the near-end hot water source and the far-end hot water source, and when the hot water consumption is small, the near-end hot water can be directly used for control. temperature, providing constant temperature hot water; when the near-end hot water storage is less than the hot water consumption, the remote hot water is intelligently regulated to replenish before the near-end hot water is exhausted, so that the outlet water always maintains a constant temperature, providing constant temperature hot water without waiting for the cold water in the remote hot water outlet pipe to be released, and reducing the hot water circulation pipe and hot water circulation loss, saving energy, and being more convenient and quick to use.

Furthermore, the timing controller includes a control module, a timing module and a water outlet trigger switch valve, the water inlet end of the water outlet trigger switch valve is connected to the water outlet end of the thermostatic valve group, and the water outlet end is connected to the water faucet, the timing module and the water outlet trigger switch valve are electrically connected to the control module respectively, and when the water faucet is switched, the water outlet trigger switch valve generates a trigger signal and controls the timing module through the control module.

From the above description, it can be seen that the water outlet trigger switch valve is used as the trigger switch of the timing module, which is linked to the water faucet. The timing controller automatically controls the cold water solenoid valve and combines the remote hot water valve to control the hot water switching of the proximal and remote water heaters. Turning on the water faucet will automatically start the control device, saving time and energy while making the operation more intelligent and convenient.

Further, the thermostatic valve group includes a first four-way thermostatic valve and a second thermostatic valve, the first thermostatic valve includes a first water inlet end, a second water inlet end, a first water outlet end and a second water outlet end, the second thermostatic valve includes a third water inlet end, a fourth water inlet end, a third water outlet end and a fourth water outlet end, the first water inlet end is connected to an external cold water pipe, the second water inlet end is connected to an external hot water pipe, the first water outlet end is connected to the third water inlet end, the second water outlet end is connected to the fourth water inlet end, the third water outlet end is connected to the water inlet end of the cold water solenoid valve, and the fourth water outlet end is connected to the water inlet end of the water outlet trigger switch valve.

From the above description, it can be seen that the thermostatic valve group is configured to provide multi-stage temperature-controlled water outlet with two thermostatic valves, and the temperature control is more accurate and safe. The thermostatic valves in the thermostatic valve group are all configured as three-position four-way valves, so that the external cold water pipe is directly connected to the water supply pipeline through the cold water end of the first thermostatic valve, and the external cold water passes through the first thermostatic valve to provide the first thermostatic valve with external cold water for adjusting the water temperature; the hot water outlet end of the first thermostatic valve is connected with the hot water inlet end of the second thermostatic valve to provide hot water to the second thermostatic valve and use external cold water to adjust the water temperature again; the water outlet end of the second thermostatic valve is connected to the water inlet end of the cold water solenoid valve to provide external cold water for heating to the proximal hot water source, and the cold water solenoid valve, the cold water end of the first thermostatic valve, the cold water end of the second thermostatic valve, and the external cold water connector are connected together through a four-way valve, so that the valve group structure of the device is connected into a compact whole, which is more convenient to use.

Furthermore, the water outlet triggered switch valve is a water flow triggered switch valve or a water pressure triggered switch valve.

From the above description, it can be seen that a water flow triggered switch valve or a water pressure triggered switch valve is used as a water outlet trigger switch. A trigger signal is generated by using a water faucet to open the water outlet and close the water flow or water pressure of the closed pipeline, thereby realizing the linkage between the water faucet and the timing controller.

Furthermore, the timing controller also includes an alarm module, and the alarm module is electrically connected to the control module.

When the preset time is reached, the alarm module sends a warning signal to remind the user of the usage time of the nearby hot water. The user can choose whether to use the remote hot water or continue to use the nearby water source.

Furthermore, the alarm module is a buzzer.

From the above description, it can be seen that the alarm module is configured as a buzzer, that is, the warning signal is a sound prompt, which makes the reminder more convenient and effective.

Furthermore, the timing controller also includes a power supply module, and the power supply module is electrically connected to the control module.

As can be seen from the above description, the device has its own power supply to provide power for the timing control circuit, etc., so that the device can be used in a location where it is inconvenient to connect an external power supply.

Furthermore, the timing controller also includes a charging module, and the charging module is electrically connected to the power module.

As can be seen from the above description, a charging module is provided to charge the power module so that the device can be reused.

Furthermore, it also includes a micro hydroelectric generator, which is arranged on the water outlet end of the thermostatic valve group and is electrically connected to the charging module.

From the above description, it can be seen that a micro hydroelectric generator is arranged in the pipeline of the device, and the kinetic energy of the water flow is converted into electrical energy to provide to the power module and the control circuit for use, making the device more convenient, safe and energy-saving.

Presetting the timing time of the timing controller;

When constant temperature hot water is needed, the required water outlet temperature is set by adjusting the thermostatic valve group, and the user determines whether to use hot water from the remote hot water source according to the needs; if so, the water tap is opened, closed and opened again in a first preset time, and the timing controller controls the water tap to be opened in a second preset time. The cold water solenoid valve is switched to the closed state or kept in the normally closed state, the remote hot water valve is switched to the open state, and the remote hot water source delivers hot water to the near-end hot water source; if not, the water tap is turned on, and the timing controller is started to start timing, and the near-end hot water source supplies hot water to the thermostatic valve group, and the thermostatic valve group mixes the external cold water and the incoming hot water to adjust the water temperature and delivers it to the water tap;

When the timing of the timing controller reaches the third preset time, the control panel issues a sound alarm, and the user determines whether to continue to use the hot water from the proximal hot water source. If so, the timing of the timing controller is restarted by closing and then opening the water faucet, and the timing controller controls the cold water solenoid valve to remain in the open state; if not, the timing controller controls the cold water solenoid valve to switch to the closed state, the remote hot water valve to switch to the open state, and the remote hot water source delivers hot water to the proximal hot water source.

From the above description, it can be seen that by using the above-mentioned control device to connect the proximal hot water source, the distal hot water source and the external cold water, intelligent adjustment of the hot water supply can be achieved, and the water tap can be used to discharge water without cold water and maintain a constant temperature during water use.

The intelligent constant temperature water outlet control device of the present invention is suitable for use in a pipe that combines proximal and distal hot water sources to supply hot water in household water use. The proximal hot water source such as a small kitchen water heater and the distal hot water source such as a large bathroom water heater and a water tap are connected through the control device. The timing control device of the control device cooperates with the electric valve structure for switching the supply of the proximal hot water source and the distal hot water source. The timing control device is linked with the water tap for control, thereby realizing intelligent allocation of proximal and distal hot water to meet different usage requirements. There is no need to design a heat circulation pipe in the hot water supply pipe, and the water outlet can maintain a constant temperature without cold water and hot water is output immediately. The use of hot water is convenient and quick, and time and energy are saved.

Referring to FIG. 1 and FIG. 2 , the first embodiment of the present invention is:

An intelligent constant temperature water outlet control device comprises a cold water solenoid valve 2, a remote hot water valve 3, a constant temperature valve group 4, a micro hydroelectric generator 6 and a timing controller 1. The timing controller 1 comprises a control module 11, a timing module 12, a water outlet trigger switch valve 5, a buzzer 13, a power module 14 and a charging module 15. The timing module 12, the water outlet trigger switch valve 5, the buzzer 13 and the power module 14 are electrically connected to the control module 11 respectively, and the charging module 15 is electrically connected to the power module 14.

As shown in Figure 2, the water inlet of the cold water solenoid valve 2 is connected to the external cold water, the water inlet of the remote hot water valve 3 is connected to the water outlet pipeline of the remote hot water source, and the water outlet of the cold water solenoid valve 2 and the water outlet of the remote hot water valve 3 are connected to the water inlet of the near-end hot water source through a three-way pipe. The outlet end of the thermostatic valve group 4 is connected to the water inlet end of the water outlet trigger switch valve 5, and the water outlet end of the water outlet trigger switch valve 5 is connected to the water faucet. When the water faucet is switched, the water outlet trigger switch valve 5 generates a trigger signal and controls the timing module 12 shown through the control module 11. The control module 11 is electrically connected to the cold water solenoid valve 2 to control the cold water solenoid valve 2 to close after the timing ends.

Among them, the water outlet trigger switch valve 5 can be a water flow trigger switch valve or a water pressure trigger switch valve, the power module 14 is a rechargeable battery, the micro hydroelectric generator 6 is arranged on the water outlet end of the thermostatic valve group 4 and is electrically connected to the charging module 15 to charge the power module 14, the near-end hot water source can be a small-volume fast-heating water heater installed under the sink of the water faucet, such as a small kitchen treasure, and the far-end hot water source can be a water heater in the bathroom. The far-end hot water valve 3 can use a solenoid valve. When a solenoid valve is used, the far-end hot water valve 3 is electrically connected to the control module 11, and the control module 11 controls the opening and closing of the far-end hot water valve 3; more preferably, the far-end hot water valve 3 uses a one-way valve, and the pressure change of the fluid in the pipe generated by the switch of the cold water solenoid valve 2 acts on the one-way valve to produce a mechanical switch change, without connecting to the control module 11, thereby reducing the power consumption of the device.

The working principle of the present invention is:

Turning on the water tap triggers the water outlet switch valve 5 to be triggered synchronously, and sends a trigger signal to the control module 11 to start the timing module 12; the cold water in the external cold water pipe enters the proximal hot water source through the cold water solenoid valve 2, and the proximal hot water source releases the stored hot water through the three-way pipe and enters the thermostatic valve group 4, and the thermostatic valve group 4 uses the external cold water mixed with the incoming hot water to adjust the temperature to the required water temperature, and then outputs it to the water tap;

The timing module 12 pre-sets a reasonable time for the near-end hot water source to provide hot water (the time can be calculated by an intelligent algorithm or according to the specific hot water source and pipeline structure characteristics). When the set time is reached, the control module 11 starts the buzzer 13 to alarm and prompt, and the hot water of the near-end hot water source is continued to be used instead of the far-end hot water source. During the alarm prompt period, the water tap is closed and then opened again, so that the water outlet triggers the switch valve 5 to send a trigger signal to the control module 11, and the control module 11 restarts the timing module 12, and the near-end hot water is continuously used;

If the remote hot water is needed when the alarm occurs, there is no need to wait for the alarm to end, and the control module 11 automatically controls the cold water solenoid valve 2 to close; if the remote hot water valve 3 uses a one-way valve, the water pressure at the outlet of the remote hot water source (the water pressure at the water inlet of the one-way valve) is greater than the water pressure at the outlet of the remote hot water valve 3 (the one-way valve), and the remote hot water valve 3 is opened, and the hot water from the remote hot water source flows into the near-end hot water source through the three-way pipe, and is discharged from the near-end hot water source. It flows into the thermostatic valve group 4 and is output after temperature adjustment; if the remote hot water valve 3 uses a solenoid valve, the control module 11 automatically controls the cold water solenoid valve 2 to close while controlling the remote hot water valve 3 (solenoid valve) to open, so that the hot water from the remote hot water source flows into the near-end hot water source through the three-way pipe.

Please refer to Figures 1 to 5, the second embodiment of the present invention is:

An intelligent constant temperature water outlet control device, based on the above embodiment 1, in this embodiment:

As shown in FIGS. 3 to 5 , the thermostatic valve group 4 includes a first thermostatic valve 41 and a second thermostatic valve 42 with four passages. The first thermostatic valve 41 includes a first water inlet end 411, a second water inlet end 412, a first water outlet end 413, and a second water outlet end 414. The second thermostatic valve 42 includes a third water inlet end 421, a fourth water inlet end 422, a third water outlet end 423, and a fourth water outlet end 424. The first water inlet end 411 is connected to an external cold water pipe, the second water inlet end 412 is connected to an external hot water pipe, the first water outlet end 413 is connected to the third water inlet end 421, the second water outlet end 414 is connected to the fourth water inlet end 422, the third water outlet end 423 is connected to the water inlet end of the cold water solenoid valve 2, and the fourth water outlet end 424 is connected to the water inlet end of the water outlet trigger switch valve 5.

Among them, the external cold water pipe outlet is connected to the first thermostatic valve 41 to supply cold water to the first thermostatic valve 41, the cold water outlet of the first thermostatic valve 41 is connected to the cold water inlet of the second thermostatic valve 42, and cold water is supplied to the second thermostatic valve 42 through the first thermostatic valve 41. The cold water outlet of the second thermostatic valve 42 is connected to the cold water solenoid valve 2 to supply cold water to the proximal hot water source; the hot water from the proximal hot water source is connected to the first thermostatic valve 41, and is sent to the second thermostatic valve 42 from the hot water outlet after the temperature is adjusted by the first thermostatic valve 41, and is sent to the water faucet from the hot water outlet of the second thermostatic valve 42 after the temperature is adjusted again by the second thermostatic valve 42.

In other equivalent embodiments, the thermostatic valve group 4 may also include one or more than two four-way thermostatic valves.

Embodiment 3 of the present invention is:

An intelligent constant temperature water outlet control method, using the intelligent constant temperature water outlet control device of the above-mentioned embodiment 1 or embodiment 2, comprises the following steps:

The timing controller 1 is preset to have a timing time, and the timing controller 1 controls the cold water solenoid valve 2 in a normally open state to remain in an open state, or immediately controls the cold water solenoid valve 2 in a closed state to switch to an open state after power is supplied;

When constant temperature hot water is needed, the required water outlet temperature is set by adjusting the thermostatic valve group 4, and the user determines whether to use hot water from the remote hot water source according to the needs; if so, the water tap is continuously opened, closed and opened again within the first preset time, so that the timing controller 1 controls the cold water within the second preset time. The water solenoid valve 2 is switched to the closed state or remains in the normally closed state, and the remote hot water valve 3 is switched to the open state, and the remote hot water source delivers hot water to the near-end hot water source; if not, the water tap is turned on, and the timing controller 1 is started to start timing, and the near-end hot water source supplies hot water to the thermostatic valve group 4, and the thermostatic valve group 4 mixes the external cold water and the incoming hot water to adjust the water temperature and deliver it to the water tap;

When the timing of the timing controller 1 reaches the third preset time, the user determines whether to continue to use the hot water of the proximal hot water source according to needs. If so, close and then open the water faucet again to restart the timing of the timing controller 1, and the timing controller 1 controls the cold water solenoid valve 2 to remain in the open state; if not, the timing controller 1 controls the cold water solenoid valve 2 to switch to the closed state, the remote hot water valve 3 to switch to the open state, and the remote hot water source delivers hot water to the proximal hot water source.

Among them, the timing controller 1 can adopt an existing timing device including a relay, and the preset timing time can be a fixed time calculated based on the hot water capacity and pipeline distance of the matching proximal hot water source and distal hot water source. The timing controller 1 can also use an intelligent timer in which an intelligent algorithm is written to calculate a settable non-fixed time. The thermostatic valve of the thermostatic valve group 4 can adopt a mechanical thermostatic valve that uses a knob to adjust the position of the inner core to change the flow aperture.

Specifically, if the user estimates that the nearby hot water cannot meet the current large demand for hot water, the user can control the cold water solenoid valve 2 of the external cold water to switch or remain closed by continuously operating the water faucet within a first preset time, such as within 3 seconds, so that the remote hot water valve 3 is opened to directly provide remote hot water, and within a second preset time, such as within 10 minutes, when the faucet is operated again, the cold water solenoid valve 2 remains closed and the hot water from the remote hot water source is continuously used; if the current hot water demand is estimated to be provided by the nearby hot water source, the water faucet is directly opened, and when it is recognized through timing that the current hot water usage is actually about to exceed the amount of hot water that the nearby hot water source can provide, the user is prompted to choose whether to switch to using the hot water from the remote hot water source.

In summary, the present invention provides an intelligent constant temperature water outlet control device and method, in which the control device is connected to the water outlet pipes of the proximal hot water source and the remote hot water source for use, and the timing control device of the control device is coordinated with the electric valve structure for switching the supply of the proximal hot water source and the remote hot water source, and the timing control device is linked with the water tap for water use to realize intelligent allocation of proximal and remote hot water to meet the usage requirements of different amounts and provide constant temperature hot water; when the proximal hot water storage is less than the hot water usage, the remote hot water is intelligently regulated to replenish before the proximal hot water is exhausted, so that the outlet water always maintains a constant temperature, and provides constant temperature hot water without waiting for the cold water in the remote hot water outlet pipe to be released, and reduces the loss of hot water circulation pipes and hot water circulation, saves energy, and outputs The water can be kept at a constant temperature without cold water and hot water can be produced immediately, making it convenient, quick and time-saving to use hot water.

When the timing of the timing controller reaches the third preset time, it is determined whether to continue to use the hot water from the proximal hot water source. If so, the timing of the timing controller is restarted, and the timing controller controls the cold water solenoid valve to remain in the open state; if not, the timing controller controls the cold water solenoid valve to switch to the closed state, the remote hot water valve to switch to the open state, and the remote hot water source delivers hot water to the proximal hot water source.
