[0025] The present disclosure will be described below through several specific embodiments. To keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and components are omitted. Please refer to... Figure 1 and Figure 2 To address the safety concerns of elderly people using domestic hot water, this utility model provides a user-friendly domestic hot water safety system, comprising:

[0026] The valve body 1 includes a hot water inlet 11, a cold water inlet 12, a mixing chamber 13, and a warm water outlet 14. The hot water inlet 11, the cold water inlet 12, and the warm water outlet 14 are all connected to the mixing chamber 13. The valve body 1 is connected to the hot water inlet pipe 2 through the hot water inlet 11, and the valve body 1 is connected to the cold water inlet pipe 3 through the cold water inlet 12.

[0027] A first electric flow regulating valve 4 and a second electric flow regulating valve 5 are provided on the hot water inlet pipe 2 and the second electric flow regulating valve 5 is provided on the cold water inlet pipe 3.

[0028] Temperature sensor 6 and flow sensor 7 are both located in the warm water chamber 15 between the mixing chamber 13 and the warm water outlet 14. Temperature sensor 6 is used to obtain the water temperature in the warm water chamber 15, and flow sensor 7 is used to obtain the flow rate in the warm water chamber 15.

[0029] The controller 8 is electrically connected to the first electric flow regulating valve 4, the second electric flow regulating valve 5, the temperature sensor 6, and the flow sensor 7, respectively.

[0030] Specifically, the controller 8 can obtain the temperature threshold valve and water usage duration required by the elderly, and then obtain the water temperature through the temperature sensor 6. If the water temperature is too low or too high, it is not suitable for the elderly or sick elderly to use. The controller can adjust the ratio of hot and cold water inlet by controlling the first electric flow regulating valve 4 and the second electric flow regulating valve 5, thereby controlling the water temperature at the set suitable temperature.

[0031] In addition, excessive water usage by the elderly can also pose safety hazards. In this embodiment, the flow rate and duration of bathing can be determined by the flow regulating valve 4, and the bathing duration can be controlled by the set duration requirements to ensure the safety of water usage for the elderly and avoid safety hazards caused by human error in ignoring water temperature and duration.

[0032] In some embodiments, the mixing chamber 13 is provided with a baffle 131, which is used to stir the hot water and cold water entering the mixing chamber 13.

[0033] In some embodiments, the deflector 131 includes a motor and deflector blades, the deflector blades being located in the mixing chamber, the deflector blades being connected to the motor shaft of the motor, and the motor being electrically connected to the controller.

[0034] The baffle 131 can fully mix the cold and hot water entering the mixing chamber 13 into warm water. This avoids inaccurate temperature detection due to uneven mixing of cold and hot water, and also prevents the uneven mixing of cold and hot water from harming the elderly. In addition, the motor of the baffle 131 is connected to the controller, which can control the baffle 131 to operate when water is entering.

[0035] In some embodiments, a prompter 9 is also included, which is electrically connected to the controller 8.

[0036] In some embodiments, the prompter includes a voice prompter and / or a display screen.

[0037] To help the elderly determine when they can bathe, this embodiment uses a prompter to alert users. For example, when the temperature stabilizes within the required temperature threshold range, a voice prompt can indicate that the temperature has reached the standard. Alternatively, the real-time temperature from the temperature sensor can be displayed on the screen, along with reminders about the duration of bathing.

[0038] In some embodiments, the hot water inlet 11 is provided with a first short connecting pipe 111, and the hot water inlet 11 is connected to the hot water inlet pipe 2 through the first short connecting pipe 111.

[0039] In some embodiments, the cold water inlet 12 is provided with a second short connector 121, and the cold water inlet 12 is connected to the cold water inlet pipe 3 through the second short connector 121.

[0040] In some embodiments, the warm water outlet 14 is provided with a third short connector 141, and the warm water outlet 141 is connected to the warm water outlet pipe 142 through the third short connector 141.

[0041] In some embodiments, the warm water outlet 14 is connected to the water outlet via a warm water outlet pipe 142, and a manual switch valve 143 is provided on the warm water outlet pipe 142.

[0042] It should be understood that during the bathing process, the water flow can be stopped by manually switching valve 143. Preferably, in some embodiments, when the water flow is stopped by manually switching valve 143, the flow rate can be detected as zero by the flow sensor 7. At this time, the timer is also stopped by the controller 8, so that the water outage time is not included in the countdown of the bathing duration, so as to avoid insufficient water supply for the user due to the water outage.

[0043] In some embodiments, the valve body 1 includes a first connector 16, the mixing chamber 13 is connected to the warm water outlet 14 through the first connector 16, the interior of the first connector 16 is the warm water chamber 15, and the temperature sensor 6 and the flow sensor 7 are disposed on the first connector 16. In some preferred embodiments, the first connector 16 is threadedly connected to the third short pipe 141 and the outlet of the mixing chamber 13 of the valve body, respectively.

[0044] In this embodiment of the invention, electric flow regulating valves are installed at both ends of the mixing chamber of the valve body. The time and temperature of water use are monitored by temperature and flow sensors. The controller can adjust the ratio of cold water and hot water flowing in according to the sensor data, thereby controlling the temperature and time of water use for the elderly and ensuring water safety.
