[0024] The utility model provides a constant temperature water supply device, which has the following beneficial effects:

[0025] 1) Constant temperature water supply is achieved, water temperature can be controlled more accurately, efficient heat exchange and constant temperature water supply are achieved, energy is used more efficiently, and a production model with low energy consumption and low emissions is achieved, meeting the society's demand for green development;

[0026] 2) The present application purposefully selects the renewable energy comprehensive conversion and utilization component to be connected to the tap water cavity of the heating water tank through a heating circulation pipeline, the renewable energy comprehensive conversion and utilization component is connected to the hot water cavity of the heating water tank through a hot water delivery pipeline, a hot water drainage temperature sensor is provided on the heating water tank, a proportional regulating valve and a heating circulation pump are provided on the heating circulation pipeline, one end of the heating water tank is connected to a hot water drainage pipeline, a hot water drainage solenoid valve is provided on the hot water drainage pipeline, the other end of the heating water tank is connected to a tap water replenishment pipeline, a tap water replenishment solenoid valve is provided on the tap water replenishment pipeline, the hot water drainage temperature sensor is electrically connected to a controller, and the controller is electrically connected to the proportional regulating valve, the heating circulation pump, the hot water drainage solenoid valve and the tap water replenishment solenoid valve respectively;

[0027] The circulation heating mode is turned on, and the renewable energy comprehensive conversion and utilization component heats the tap water passing through it to form hot water. The hot water is transported to the hot water cavity of the heating water tank through the hot water delivery pipe. The system can automatically adjust and close the circulation heating mode according to the drainage temperature. Specifically, when the hot water drainage temperature sensor detects that the hot water drainage temperature reaches the upper threshold value, the system automatically switches to the drainage / direct heating mode. The controller receives the signal that the hot water temperature in the heating water tank reaches the upper threshold value and controls the closing of the proportional regulating valve and the heating circulation pump, and controls the opening of the tap water replenishment solenoid valve and the hot water drainage solenoid valve at the same time. Through the replenishment of tap water and the discharge of hot water, the newly added tap water will absorb part of the heat of the hot water and heat up, thereby realizing the effective exchange of heat in the heating water tank and more efficient use of energy, and the discharged hot water realizes constant temperature water supply;

[0028] The system can automatically adjust and resume the circulation heating mode according to the drainage temperature. Specifically, when the hot water drainage temperature sensor detects that the hot water drainage temperature reaches the lower threshold value, the controller receives the signal that the hot water drainage temperature reaches the lower threshold value and controls the closing of the tap water replenishment solenoid valve and the hot water drainage solenoid valve, and controls the opening of the proportional regulating valve and the heating circulation pump, so that the tap water after heat exchange is transported again through the renewable energy comprehensive conversion and utilization component, and the heating water tank is circulated and heated and hot water is input;

[0029] By repeating the above steps, the water temperature can be controlled more accurately under the intelligent regulation of the controller. The system can keep the temperature of the hot water in the heating tank fluctuating within a relatively stable range, thereby achieving constant temperature water supply. This not only improves energy utilization efficiency, but also ensures the stability of constant temperature water supply.

[0030] 3) The renewable energy comprehensive conversion and utilization component is a photovoltaic and thermal integrated component or an air energy heat pump unit;

[0031] The present application purposefully selects a photovoltaic-thermal integrated assembly, which combines photovoltaic and thermal technologies and can simultaneously utilize solar energy to generate electricity and heat. In the heating mode, the photovoltaic-thermal integrated assembly absorbs solar energy and converts it into thermal energy, circulates and heats the heating water tank to input hot water, and realizes the preparation of hot water. This method not only improves the comprehensive utilization efficiency of solar energy, but also reduces the consumption of traditional energy.

[0032] The present application purposefully selects an air energy heat pump unit, which utilizes the heat energy in the air and converts low-temperature heat energy into high-temperature heat energy through the reverse Carnot cycle principle. Compared with traditional heating methods, the air energy heat pump unit has a higher energy efficiency ratio (COP), that is, the output heat energy far exceeds the input electrical energy, thereby achieving high efficiency and energy saving;

[0033] Furthermore, the air energy heat pump unit is not restricted by weather and seasons, and can operate stably in various environments to provide continuous heat energy for the heating water tank;

[0035] 4) A partition plate is movably provided in the heating water tank, and the initial position of the partition plate is located at the other end of the heating water tank. When the hot water starts to be drained, the pressure at a position near one end of the heating water tank decreases due to the discharge of hot water. At the same time, due to the entry of tap water from the other end of the heating water tank, the pressure at a position near the other end of the heating water tank increases relatively. This pressure difference between the upper and lower parts causes the partition plate to move along the inner wall of the heating water tank from the other end of the heating water tank toward one end of the heating water tank;

[0036] The outer side surface of the partition plate and the inner side surface of the heating water tank are coaxial surfaces, and the fitting clearance between the outer side surface of the partition plate and the inner side surface of the heating water tank is 0.5-1mm. Since the fitting clearance is very small, the partition plate moves from the other end of the heating water tank toward one end of the heating water tank to a certain position, which can block the direct contact between hot water and tap water, thereby reducing mixing. Due to the blocking effect of the partition plate, tap water is mainly restricted to the area inside the heating water tank near the other end of the heating water tank, while hot water is restricted to the area inside the heating water tank near one end of the heating water tank, further improving the heat exchange efficiency.

[0037] 5) The present application purposefully selects one end of the heating water tank to be connected to the heat preservation water supply tank through the hot water drainage pipeline, the heat preservation water supply tank is provided with a water temperature probe, one side of the heat preservation water supply tank is connected to a constant temperature auxiliary heating element, the water temperature probe is electrically connected to the controller, and the controller is electrically connected to the constant temperature auxiliary heating element;

[0038] When the water temperature probe detects that the water temperature in the insulated hot water tank is lower than the upper limit of the constant temperature water supply temperature threshold (for example, 55°C), the controller receives the signal that the water temperature in the insulated hot water tank is lower than the constant temperature water supply temperature threshold and controls the constant temperature auxiliary heating element to operate, thereby being able to more accurately control the water temperature, achieve constant temperature water supply, and ensure the stability of the constant temperature water supply.

[0039] 6) The present application purposefully selects the outer side of the inner cavity of the heat-insulating water supply tank and / or the outer side of the inner cavity of the heating water tank to be provided with a stainless steel 304 inner liner, a stainless steel 201 outer liner and a polyurethane foam insulation layer from the inside to the outside, and selects a polyurethane foam insulation layer and stainless steel of different materials to reduce heat loss during constant temperature water supply storage;

The polyurethane foam insulation layer is selected to reduce heat loss during the constant temperature water supply transmission process, and the aluminum protective layer is selected as the outer protective layer to prevent the polyurethane foam insulation layer from aging and falling off in the outdoor environment.

[0041] 7) Installing a filter on the heating circulation pipeline plays a role in protecting equipment and improving water quality. The filter reduces the resistance in the pipeline, allowing hot water to flow more smoothly during the circulation process, thereby improving the thermal efficiency of the system.

[0052] The system can automatically adjust and resume the circulation heating mode according to the drainage temperature. Specifically, when the hot water drainage temperature sensor 5 detects that the hot water drainage temperature reaches the lower threshold value, the controller 13 receives the signal that the hot water drainage temperature reaches the lower threshold value and controls the closing of the tap water replenishment solenoid valve 11 and the hot water drainage solenoid valve 9, and controls the opening of the proportional regulating valve 6 and the heating circulation pump 7, so that the tap water after the heat exchange is transported again through the renewable energy comprehensive conversion and utilization component 1, and the heating water tank 3 is circulated and heated to input hot water;

[0053] By repeating the above steps, the water temperature can be controlled more accurately under the intelligent regulation of the controller. The system can keep the temperature of the hot water in the heating water tank 3 fluctuating within a relatively stable range, thereby achieving constant temperature water supply, which not only improves the energy utilization efficiency, but also ensures the stability of constant temperature water supply.

[0055] The present application purposefully selects the photovoltaic-thermal integrated assembly 111, which combines photovoltaic and photothermal technologies and can simultaneously utilize solar energy to generate electricity and heat. In the heating mode, the photovoltaic-thermal integrated assembly 111 absorbs solar energy and converts it into thermal energy, circulates and heats the heating water tank 3, and realizes the preparation of hot water. This method not only improves the comprehensive utilization efficiency of solar energy, but also reduces the consumption of traditional energy.

[0056] The present application purposefully selects the air energy heat pump unit 112, which utilizes the heat energy in the air and converts low-temperature heat energy into high-temperature heat energy through the reverse Carnot cycle principle. Compared with the traditional heating method, the air energy heat pump unit 112 has a higher energy efficiency ratio (COP), that is, the output heat energy far exceeds the input electrical energy, thereby achieving high efficiency and energy saving;

When the hot water starts to be drained, the pressure in the heating water tank 3 near one end of the heating water tank 3 decreases due to the discharge of hot water. At the same time, due to the entry of tap water from the other end of the heating water tank 3, the pressure in the heating water tank 3 near the other end of the heating water tank 3 increases relatively.

[0075] The circulation heating mode is turned on. The photovoltaic-thermal integrated component 111 heats the tap water passing through it to form hot water. The hot water is transported to the hot water cavity of the heating water tank 3 through the hot water transport pipe 4. The system can automatically adjust and close the circulation heating mode according to the drainage temperature. Specifically, when the hot water drainage temperature sensor 5 detects that the hot water drainage temperature reaches the upper threshold value, the system automatically switches to the drainage / direct heating mode. The controller receives the signal that the hot water temperature in the heating water tank 3 reaches the upper threshold value (for example, 55°C) and controls the closing of the proportional regulating valve and the heating circulation pump.

The system can automatically adjust and close the circulation heating mode according to the drainage temperature. Specifically, when the hot water drainage temperature sensor 5 detects that the hot water drainage temperature reaches the upper threshold value (for example, 55°C), the system automatically switches to the drainage / direct heating mode.

When the hot water drainage temperature sensor 5 detects that the hot water drainage temperature reaches the lower threshold value (for example, 15°C), the controller 13 receives the signal that the hot water drainage temperature reaches the lower threshold value and controls the closing of the tap water replenishment solenoid valve 11 and the hot water drainage solenoid valve 9, and controls the opening of the proportional regulating valve 6 and the heating circulation pump 7, so that the tap water after heat exchange is filtered and transported to the air energy heat pump unit 112 again through the heating circulation pipeline 2 for heating to form hot water, and the heating water tank 3 is circulated and heated and hot water is input;
