Description

Technical Field

[0001] The utility model relates to the technical field of water temperature regulation, and more specifically to a combined device for quickly and automatically regulating outlet water temperature of hot and cold water. Background Art

[0002] Traditional water temperature regulation is done by adding hot water inside the water tank to the user-set temperature, then leading the hot water to the specified location through a pipe, and manually adjusting the regulating valve to achieve the water outlet temperature. The user needs to constantly adjust the regulating valve to keep the water temperature at a constant state, which reduces the user's water comfort and also causes a waste of water resources.

[0003] The prior art discloses a water dispenser that automatically adjusts the outlet water temperature, comprising a hot water storage tank, a cold water storage tank, a first digital flow regulating valve, a second digital flow regulating valve, a hot water outlet pipe, a cold water outlet pipe, and a warm water outlet pipe, wherein one end of the hot water outlet pipe is connected to the bottom of the hot water storage tank, one end of the cold water outlet pipe is connected to the bottom of the cold water storage tank, the other end of the hot water outlet pipe and the other end of the cold water outlet pipe are connected to the warm water outlet pipe through a three-way valve, and the first digital flow regulating valve and the second digital flow regulating valve are fixedly arranged on the hot water outlet pipe and the cold water outlet pipe. The solution ensures that the hot water and the cold water flow out at the same time by adjusting the hot water and the cold water outlet flow, thereby ensuring that the hot water and the cold water are evenly mixed when the water is discharged.

[0004] However, in the prior art, flow regulating valves are respectively arranged on the hot water outlet pipe and the cold water outlet pipe, and there is a hysteresis in controlling the opening of the two flow regulating valves at the same time, which makes it difficult to ensure the balance of the total amount of cold and hot water; and after the cold water and the hot water are mixed, they flow out directly from the outlet pipe. When the temperature of the cold and hot water after mixing is not determined, there is a possibility that the water temperature will be inconsistent with the set temperature when the water is delivered; secondly, the path between the cold and hot water outlet pipes is long, and the water temperature may lose temperature during the flow process, resulting in a deviation in the outlet water temperature. Therefore, there is a technical problem in the prior art that the balance of the total amount of cold and hot water and the outlet water temperature cannot be ensured. Utility Model Content

[0005] The utility model aims to overcome the deficiency of the prior art that the total amount of cold and hot water can not be balanced and the outlet water temperature can not be guaranteed, and to provide a combined device for quickly and automatically adjusting the outlet water temperature of cold and hot water.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

The regulating device is arranged in the mixing water chamber. Since the regulating device can simultaneously adjust the outlet flow rates of the hot water inlet and the cold water inlet and keep the total water output of the two unchanged, it means that the outlet flow rate of the hot water inlet and the outlet flow rate of the cold water inlet are in a relationship of increase and decrease, thereby ensuring the balance of the total amount of hot and cold water. Since the water flowing out of the mixing water outlet flows into the outlet valve after passing through the temperature sensor, the regulating device and the outlet valve are both connected to the temperature sensor by signal. When the temperature sensor detects that the water temperature does not reach the set temperature, the temperature sensor controls the outlet valve to Water that meets the water temperature is discharged from the wastewater channel and flows back into the water tank. When the temperature sensor controls the regulating device to mix the water temperature to reach the set temperature, the temperature sensor controls the water outlet valve to discharge water that meets the water temperature from the water outlet channel, ensuring that the water flowing out meets the preset temperature, avoiding the deviation of the water temperature from the set temperature due to the water being delivered without determining the temperature after the hot and cold water are mixed. In addition, the regulating valve, the temperature sensor and the water outlet valve are arranged compactly to shorten the water flow path and avoid loss of temperature during the flow process, effectively solving the technical problem in the prior art that the balance of the total amount of hot and cold water and the outlet water temperature cannot be guaranteed.

[0009] Furthermore, it also includes an adjustment base, the adjustment valve, the temperature sensor and the water outlet valve are all arranged on the adjustment base, an adjustment cover is arranged at the bottom of the adjustment base, a mixed water channel is formed between the adjustment cover and the adjustment base, the two ends of the mixed water channel are respectively connected to the mixed water outlet and the water outlet valve, and one end of the temperature sensor is placed in the mixed water channel. The adjustment valve, the temperature sensor and the water outlet valve are all integrated on the adjustment base, so that a mixed water channel with two ends respectively connected to the mixed water outlet and the water outlet valve is formed between the adjustment cover and the adjustment base, so as to achieve the purpose of compact structural design.

[0010] Furthermore, the regulating base and the regulating cover are respectively provided with a plurality of water mixing baffles in the mixed water channel. The water mixing baffles can change the flow state of the water flow and promote the mixing of cold and hot water.

[0011] Furthermore, the water mixing baffles are distributed on both sides of the temperature sensor. The water mixing baffles are distributed on both sides of the temperature sensor to ensure that the water is fully mixed in the mixed water channel.

[0012] Further, the regulating device includes a fixed valve core arranged in the mixing water chamber and a regulating valve core arranged on the fixed valve core, the fixed valve core is provided with a hot water tank and a cold water tank above and below, the regulating valve core is provided with a hot water hole and a cold water hole above and below, the center positions of the fixed valve core and the regulating valve core are coaxially provided with a water outlet hole, the hot water tank and the cold water tank are connected with the hot water inlet and the cold water inlet respectively, the cross-sections of the hot water hole and the cold water hole can overlap or partially overlap with the cross-sections of the hot water tank and the cold water tank respectively, and the mixing water chamber is connected with the mixing water outlet through the water outlet hole; the regulating valve core can rotate around the axis of the water outlet hole, the cross-sectional overlapping area of ​​the hot water hole and the hot water tank and the cross-sectional overlapping area of ​​the cold water hole and the cold water tank can increase or decrease with the rotation of the regulating valve core, and the sum of the cross-sectional overlapping area of ​​the hot water hole and the hot water tank and the cross-sectional overlapping area of ​​the cold water hole and the cold water tank remains unchanged. Since the cross-sectional overlapping area between the hot water hole and the hot water tank and the cross-sectional overlapping area between the cold water hole and the cold water tank can increase or decrease with the rotation of the regulating valve core, and the sum of the cross-sectional overlapping area between the hot water hole and the hot water tank and the cross-sectional overlapping area between the cold water hole and the cold water tank remains unchanged, it means that with the rotation of the regulating valve core, the changing trend of the cross-sectional overlapping area between the hot water hole and the hot water tank is opposite to the changing trend of the cross-sectional overlapping area between the cold water hole and the cold water tank. The function of simultaneously adjusting the hot water flow rate and the cold water flow rate by rotating the regulating valve core forward and backward is realized, and the total amount of hot water flow rate and cold water flow rate is ensured to remain unchanged, thereby improving the stability of the mixed water temperature adjustment.

[0013] Furthermore, the cross-sectional shape of the hot water tank and the cold water tank is an arc-shaped strip arranged around the water outlet on the fixed valve core, the cross-sectional area of ​​the hot water tank and the cold water tank gradually decreases from the head end to the tail end, and the hot water tank and the cold water tank are arranged around the water outlet in opposite directions. The cross-sectional shape of the hot water tank and the cold water tank is designed to be an arc-shaped strip arranged around the water outlet on the fixed valve core, because the cross-sectional area of ​​the hot water tank and the cold water tank gradually decreases from the head end to the tail end, and the hot water tank and the cold water tank are arranged around the water outlet in opposite directions, the function of simultaneously adjusting the hot water flow and the cold water flow by rotating the regulating valve core forward and backward is realized, which has the advantages of simple structure and convenient operation.

The regulating valve core is driven to rotate by the motor, and the motor is connected to the temperature sensor signal to achieve automatic adjustment of the water temperature; since the valve core rod is passed through the regulating valve, a valve core sealing ring is provided between the valve core rod and the regulating valve to ensure the air tightness of the water mixing chamber.

[0015] Furthermore, a micro switch is provided on the top of the regulating valve, and a torsion bar is provided between the valve core rod and the output end of the motor. When the cross-sectional overlap area of ​​the hot water hole and the hot water tank is the largest and the cold water hole and the cold water tank are closed, or the cross-sectional overlap area of ​​the cold water hole and the cold water tank is the largest and the hot water hole and the hot water tank are closed, the torsion bar touches the micro switch, and the micro switch is connected to the motor signal. When the torsion bar touches the micro switch, the micro switch controls the motor to turn off, and at this time the regulating valve only outputs cold water or hot water, realizing the function of continuous water supply at two end value water temperatures in the power-off state.

[0016] Furthermore, a water outlet cavity is provided in the water outlet valve, and the water flowing out of the mixed water outlet flows into the water outlet cavity after passing through the temperature sensor, and the water outlet cavity is connected with the wastewater channel and the water outlet channel; a solenoid valve is provided on the top of the water outlet valve, and the solenoid valve is provided with a retractable iron core, and a sealing head is provided at the end of the iron core, and the sealing head can block the wastewater channel or the water outlet channel as the iron core is retracted, and the solenoid valve is connected to the temperature sensor signal. Since the sealing head can block the wastewater channel or the water outlet channel as the iron core is retracted, automatic switching is achieved by converting the retractable movement of the iron core into a closed state to control different channels, and connecting the solenoid valve to the temperature sensor signal, thereby improving the response speed.

[0017] Furthermore, a spring is provided between the iron core and the electromagnetic valve, and the spring applies a force to the iron core to keep the sealing head blocking the water outlet channel. Since the spring applies a force to the iron core to keep the sealing head blocking the water outlet channel, the water outlet channel is normally closed when the electromagnetic valve is not powered, while the wastewater channel is normally open, ensuring continuous delivery of wastewater. The electromagnetic valve is powered on to open the water outlet channel to deliver water only when it is needed, and the functional design is more reasonable.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

The adjusting device is arranged in a water mixing chamber. Since the adjusting device can adjust the outlet water flow rates of the hot water inlet and the cold water inlet at the same time and keep the total water output of the two unchanged, it means that the outlet water flow rate of the hot water inlet and the outlet water flow rate of the cold water inlet are in a relationship of increase and decrease, thereby ensuring the balance of the total amount of hot and cold water, and effectively solving the technical problem in the prior art that the balance of the total amount of hot and cold water cannot be ensured.

[0020] The utility model discloses a combined device for quickly and automatically adjusting the outlet temperature of hot and cold water.
