Problems solved by technology

[0005] During use, there will be a certain distance from the faucet in the water heater. Every time the user turns off the faucet, the water between the hot water pipe and the water heater is still hot, causing waste of hot water. water, the water heater will restart the heating function, this section of hot water always exists, resulting in waste of energy

Embodiment Construction

[0018] Such as figure 1 As shown, it is a functional block diagram of a water heater 10 according to an embodiment, including: a water inlet pipe 101 , a water flow switch 102 , a heater 103 , a water outlet pipe 104 and a delay module 105 .

[0019] The water inlet pipe 101 , the heater 103 and the water outlet pipe 104 are connected in sequence, and the water flow switch 102 is connected with the water inlet pipe 101 and the heater 103 . The delay module 105 is connected with the water flow switch 102 .

[0020] The delay module 105 is connected with the water flow switch 102 .

[0021] The water inlet pipe 101 is used to communicate with the tap water pipe.

[0022] The water outlet pipe 104 is used to communicate with the faucet.

[0023] The heater 103 is used for heating water, which can be gas fired or electric.

[0024] The water flow switch 102 is used to start the heater 103 when the water flow rate reaches a preset threshold, and turn off the heater 103 when the...

Abstract

A water heater comprises a water inlet pipe, a water flow switch, a heater, a water outlet pipe and a time delay module. The heater is used for heating water. The water flow switch is used for starting the heater when water flow speed reaches preset threshold value, and closing the heater when the water flow speed value is lower than the preset threshold value. The time delay module is used for starting counting when the water flow switch conducts closing motion, and conducting zero clearing when the water flow switch conducts opening motion. The water flow switch is used for staring the heater when the water flow speed reaches the preset threshold value and time counted by the time delay module reaches preset time after closing. Thus, the time interval from closing of the heater to next starting of the heater is limited. A user closes a faucet and then instantly opens the faucet in hot water releasing processes. Consequently, the time difference does not reach the preset time, thus, the water flow switch can not start the heater, but releases hot water remained in a pipeline, and therefore hot water can not be wasted, and energy resources are saved.

Description

technical field [0001] The present invention relates to water heaters, in particular to electric control water heaters. Background technique [0002] Water heaters are already essential appliances for furniture. Water heaters usually include gas water heaters, electric water heaters, and solar water heaters. [0003] The heating method of water heaters and electric water heaters is instant heating, that is, users start to boil water when they need hot water. [0004] The heating switch of the water heater is usually judged according to the water flow velocity of the hot water pipe. When the water flow velocity reaches a preset threshold, the switch will be triggered to turn on the heating function. [0005] During use, there will be a certain distance from the faucet in the water heater. Every time the user turns off the faucet, the water between the hot water pipe and the water heater is still hot, causing waste of hot water. Water, the water heater will restart the heati...
