Detailed Implementation
[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figures 1-3 In this embodiment of the utility model, a water-saving appliance with temperature detection function includes a water-saving tank 1. A water-saving mechanism that penetrates into the inner cavity of the water-saving tank 1 is installed on the top of the water-saving tank 1. A second mounting sleeve 5 that protrudes upward is integrally formed on the top of the water-saving tank 1 on one side of the water-saving mechanism. A liquid level sensor 6 is installed on the inner wall of the second mounting sleeve 5. A pumping mechanism connected to the toilet inlet tank is installed on the lower outer side of the water-saving tank 1.
[0017] In this embodiment: When taking a shower, the water enters the water-saving mechanism through the mixing valve and then enters the water-saving tank 1. During the water flow, the temperature is monitored by the temperature sensor 16. When the temperature gradually rises to the preset temperature, the temperature sensor 16 sends an electrical signal to the controller, which controls the third solenoid valve 17 to close. At this time, the water enters the shower head through the water-saving mechanism for showering.
[0018] When the water inside the water-saving tank 1 reaches the preset volume, the liquid level sensor 6 sends an electrical signal to the controller. The controller then controls the first solenoid valve 13 to close and the second solenoid valve 14 to open. When water needs to be added to the toilet tank, the pumping mechanism delivers the water inside the water-saving tank 1 to the toilet tank to avoid water waste.
[0019] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The water-saving mechanism includes an inlet pipe 2 that extends from the top of the water-saving tank 1 into the inner cavity of the water-saving tank 1. The top of the inlet pipe 2 is connected to the output port of the mixing valve. An outlet pipe 3, integrally formed on the outer wall of the inner cavity of the water-saving tank 1, extends to the top of the outside of the water-saving tank 1. The output end of the outlet pipe 3 is connected to the shower head. The water-saving mechanism also includes a first mounting sleeve 4 integrally formed on the outer wall of the inlet pipe 2. The first mounting sleeve 4 is located outside the water-saving tank 1. A temperature sensor 16 is installed on the inner wall of the first mounting sleeve 4. A third solenoid valve 17 is installed at the output port of the inlet pipe 2. The temperature sensor 16 and the third solenoid valve 17 are electrically connected through a controller.
[0020] In this embodiment: When taking a shower, after opening the mixing valve, when the water temperature is low, the temperature sensor 16 sends an electrical signal to the controller, which then controls the third solenoid valve 17 to open. At this time, the water enters the water-saving tank 1 through the inlet pipe 2. When the water temperature gradually rises and reaches the preset temperature, the temperature sensor 16 sends an electrical signal to the controller again, which then controls the third solenoid valve 17 to close. At this time, the water in the inlet pipe 2 enters the shower head through the outlet pipe 3 for showering, thus avoiding the need to run cold water before showering and achieving the purpose of saving water.
[0021] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3The water pumping mechanism includes an output pipe 7 fixedly installed below one side of the water-saving tank 1. A water pump 9 is fixedly installed at the output end of the output pipe 7. A connecting pipe 10 is fixedly installed at the output end of the water pump 9. The output end of the connecting pipe 10 is connected to the lower input end of the three-way pipe 11. A water supply pipe 15 is connected to the upper output end of the three-way pipe 11. The side input end of the three-way pipe 11 is connected to the input pipe 12. The mounting base of the water pump 9 is installed on the top of the base plate 8. The base plate 8 is integrally formed with one side of the outer wall of the water-saving tank 1. The water pumping mechanism also includes a second solenoid valve 14 installed on the outer wall of the output end of the connecting pipe 10 and a first solenoid valve 13 installed on the outer wall of the output end of the input pipe 12. The liquid level sensor 6 is electrically connected to the first solenoid valve 13 and the second solenoid valve 14 through a controller.
[0022] In this embodiment: after flushing the toilet, the toilet tank needs to be filled with water;
[0023] If the water in the water-saving tank 1 is insufficient, the liquid level sensor 6 sends an electrical signal to the controller, which controls the second solenoid valve 14 to close and the first solenoid valve 13 to close. The input pipe 12 is connected to the water network pipe, and the water in the network pipe enters the toilet tank under pressure.
[0024] If there is enough water in the water-saving tank 1, the liquid level sensor 6 sends an electrical signal to the controller, and the controller controls the second solenoid valve 14 to open and the first solenoid valve 13 to close. At this time, the water pump 9 pumps the water in the water-saving tank 1 into the toilet tank.
[0025] The water inside the water-saving tank 1 is sufficient to fill the toilet tank once, which is the minimum preset threshold of the liquid level sensor 6.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
