Description

Technical Field

[0001] The utility model relates to the technical field of bathrooms, in particular to a wireless controlled pre-drain cold water shower. Background Art

[0002] Existing showers generally include a temperature control valve to mix the hot water entering the hot water inlet channel and the cold water entering the cold water inlet channel, so that water with a suitable temperature can flow out for showering. However, when using a water heater, there is often a long pipeline between the water heater and the valve that controls the shower. Especially in some centralized water supply usage scenarios and when using solar energy heating, hot water is easily connected to the shower position through pipelines from different floors or even the roof. When these long connecting pipelines are used, the cold water in the pipeline needs to be drained before the hot water can be discharged, resulting in a large amount of water waste and greatly reducing the user experience. At the same time, when taking a bath in winter, a large amount of cold water discharge will make the bathroom temperature lower. In the process of use, after the hot water in the water heater is used up, the cold water will be transported to the shower head through the pipeline. At this time, the user will feel cold and uncomfortable due to the spray of cold water, thereby reducing the use effect and wasting water resources to a certain extent. Utility Model Content

If cold water enters the connecting port in the connecting channel through the water inlet pipe, the cold water in the connecting port flows back to the water heater through the return pipe, and the air bag keeps shrinking when cold water flows in. When hot water enters the connecting port in the connecting channel through the water inlet pipe, the air bag expands due to the heat and pushes the connecting channel to move to the left. The connecting port in the connecting channel is connected to the water outlet. At this time, hot water enters the water inlet cavity and the connecting port through the water inlet, and enters the water outlet and the water outlet pipe through the connecting port.

[0009] Beneficial effects:

[0010] 1. The wireless controlled pre-drain cold water shower, when using the water heater, turns on the water pump through the wireless control module to transport the water in the water heater to the water inlet pipe, and then the water inlet pipe transports the water to the connecting port connected above the water inlet. If the water transported by the water inlet pipe is cold water at this time, the air bag arranged on the side of the connecting channel is kept contracted by the cold water, so that the cold water entering the connecting port is transported to the return port. At this time, the return pipe connected above the return port transports the cold water back to the water heater, avoiding the need to drain the cold water in the pipeline before discharging the hot water during use, resulting in a large amount of water waste and greatly reducing the user experience. At the same time, when taking a bath in winter, the large amount of cold water discharged will make the bathroom The temperature drops, which can easily cause the user to catch a cold. The water pump is turned on through the wireless control module, and the water pump then transports the water in the water heater to the water inlet pipe, and the water inlet pipe transports the water to the connecting port. If the water transported by the water inlet pipe is hot water at this time, it is fixedly connected with the water inlet cavity through the connecting port, and the hot water entering the connecting port will also enter the water inlet cavity. At this time, the air bag expands due to the heat generated by the hot water, so that the connecting channel moves to the left through the expansion of the air bag and is connected to the water outlet at the bottom of the water outlet pipe. At this time, hot water enters the water inlet cavity through the water inlet, and enters the connecting port through the water inlet cavity, and is transported to the water outlet through the connecting port, so that the water outlet pipe transports the hot water to the shower head, and the hot water is sprayed through the shower head.

[0011] 2. The wireless controlled pre-drain cold water shower, when the hot water in the water heater is used up, the temperature of the hot water transported by the water inlet pipe decreases. At this time, the air bag gradually shrinks due to the reduction of heat, and the connecting channel returns to its original position due to the contraction of the air bag. At this time, the wireless control module starts the water pump, so that the transported cold water enters the return water port from the connecting port, and transports the cold water to the water heater through the return water pipe, which effectively avoids the waste of water during use and prevents the user from getting cold and uncomfortable due to the spray of cold water, thereby greatly saving the waste of water resources, while improving the use effect of the water heater and meeting the use needs of the user.
