Description

Technical Field

[0001] The utility model belongs to the technical field of hot water control equipment, and in particular relates to an induction type hot water control equipment. Background Art

[0002] With the development of science and technology and the improvement of people's living standards, the pursuit of quality of life is getting higher and higher. In life, there is often such a phenomenon that because the hot water in the water pipe is already at a low temperature, it takes a long time to open the faucet to release hot water, especially in the cold winter in the north. If the water heater is far away from the wash basin, it takes a long time to wait, which not only requires users to wait, but also wastes a lot of water resources.

[0003] In order to solve this problem, some water heaters that can always maintain a constant temperature have appeared on the market. After the temperature drops, this type of water heater will circulate the water in the pipe back to the water heater for reheating to maintain a constant temperature. However, the cost of this type of water heater is relatively high. Although it has certain advantages in maintaining the temperature of hot water, its cost makes it unsuitable for all users, especially those families with limited economic conditions, and it is difficult to popularize it in the market.

[0004] Therefore, we propose an induction hot water control device to solve the above technical problems. Utility Model Content

[0005] In order to solve the technical problems in the prior art that it takes a long time to release hot water, and constant temperature water heaters are costly and difficult to popularize, the utility model proposes an induction hot water control device.

[0006] The technical solution adopted by the utility model is as follows:

[0007] An induction hot water control device comprises a three-way pipe, a sensing component and a control box, wherein the three pipe openings of the three-way pipe are respectively connected to a hot water supply pipe, a water pipe and a recovery water pipe, and the three-way pipe is provided with a drain valve on one side of the recovery water pipe. The sensing component comprises an induction signal switch, an induction signal receiver and a temperature sensing probe, the induction signal switch cooperates with the induction signal receiver, the temperature sensing probe extends into the three-way pipe, the control box is sleeved on the three-way pipe, a circuit board is provided in the control box, and the drain valve, the induction signal receiver and the temperature sensing probe are all electrically connected to the circuit board.

[0008] By adopting the above technical scheme, when the utility model is used, the hot water supply pipe, the water pipe and the recycling water pipe are respectively connected at the three pipe openings of the three-way pipe, the hot water supply pipe is connected to the water heater, and the water pipe is connected to the faucet. The user installs the induction signal switch at the entrance door, kitchen door or bathroom door of the home according to the water use habit. After the user enters the door, the induction signal switch is triggered in advance to send a signal to the induction signal receiver. After the induction signal receiver receives the signal, it transmits the signal to the circuit board in the control box. After receiving the signal, the circuit board controls the drain valve to open, and the water with lower temperature in the hot water supply pipe is discharged in advance through the recycling water pipe. At the same time, the water heater is started to heat cold water. When the water temperature rises to the set value monitored by the temperature sensing probe, the circuit board controls the drain valve to close. When the user uses water, the faucet can be directly opened to release hot water, which reduces the waiting time of the user, and the water discharged from the recycling water pipe can be collected in a container, thereby saving water resources. Of course, without considering energy consumption, further optimization can be made. After the temperature monitored by the temperature sensing probe is lower than the set value, the drain valve can also be opened to discharge the cold water in the hot water supply pipe so that the user can use hot water. The utility model senses that the user triggers an induction signal switch or monitors that the water temperature in the hot water supply pipe is lower than a set value through a temperature sensing probe, thereby opening the drain valve to discharge cold water in advance and triggering the water heater to heat the water. Compared with the prior art, there is no need to improve the water heater, thereby reducing equipment costs and effectively reducing the time users have to wait for hot water after turning on the faucet. The utility model is easy to use and can be popularized in most households.

[0009] In a further technical solution, the hot water supply pipe and the water recovery pipe are both connected to the water heater.

[0010] By adopting the above technical solution, by connecting the hot water supply pipe and the recovery water pipe to the water heater, the water discharged from the recovery water pipe can be circulated back into the water heater to increase the temperature, which can effectively reduce the waste of water resources.

[0011] In a further technical solution, a return water circulation pump is installed on the recovery water pipe, and the return water circulation pump is electrically connected to the circuit board.

[0012] By adopting the above technical solution, after the user triggers the induction signal switch, the circuit board starts the return water circulation pump, and the return water circulation pump can quickly circulate the cold water in the hot water supply pipe back to the water heater, which is beneficial to use and reduces water costs.

[0013] In a further technical solution, the drainage valve is an electric valve, a pneumatic valve or a hydraulic valve.

[0014] Using the above technical solution, electric valves, pneumatic valves and hydraulic valves are all relatively mature technologies with fast response and high precision. They can effectively meet the use requirements and improve the degree of automation of drainage valve control.

[0015] In a further technical solution, the induction signal switch adopts one of an inductive induction switch, an ultrasonic induction switch or an infrared induction switch.

[0016] Using the above technical solution, inductive sensing switches, ultrasonic sensing switches or infrared sensing switches are all relatively mature technologies with fast response and high accuracy. They can effectively identify users and discharge cold water in advance to reduce the waiting time for users to use water.

[0017] In a further technical solution, the outer side of the hot water supply pipe is provided with a heat-insulating layer.

[0018] By adopting the above technical solution, the thermal insulation effect of the hot water supply pipe can be effectively improved through the thermal insulation layer, thereby effectively reducing the number of water circulations and saving energy consumption.

[0019] In a further technical solution, a temperature control knob is also included, and the temperature control knob is electrically connected to the circuit board and is used to adjust the water temperature setting value.

[0020] By adopting the above technical solution, the temperature control knob allows the user to adjust the water temperature setting value at any time according to the season, weather and personal feelings, thereby improving the user experience and meeting the water temperature requirements of different users.

[0021] In a further technical solution, a display is also included, which is electrically connected to the temperature sensing probe and is used to display the monitored temperature of the temperature sensing probe.

[0022] By adopting the above technical solution, the display can show the monitored temperature of the temperature sensing probe, so that the user can know the water temperature at any time, prevent scalding accidents caused by abnormal temperature, and protect the user's safety.

[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0024] The utility model senses the user to trigger the induction signal switch, discharges cold water in advance, and triggers the water heater to heat the water at the same time. The water discharged from the recovery pipe can be quickly circulated back into the water heater for heating through the return water circulation pump, which can effectively reduce the waste of water resources and reduce water use costs. Compared with the existing technology, there is no need to improve the water heater, thereby reducing equipment costs, and effectively reducing the time users have to wait for hot water after turning on the faucet. It is easy to use and can be popularized in most households. BRIEF DESCRIPTION OF THE DRAWINGS
