Embodiment Construction

[0015] Such as figure 1 Shown: an instant hot water heater, which can be a gas water heater or an electric water heater, including a water heater body 1, a hot water outlet pipe 3 connected to it, a cold water inlet pipe 2, which communicates with the hot water outlet pipe 3 and cold water The return pipe 7 of the water inlet pipe 2 and a water outlet valve 6 are also provided with a pump 5 on the return pipe 7. In this embodiment, the pump 5 is a gear pump. It also includes a dual-control temperature relay 4 installed on the hot water outlet pipe 3, and the water outlet valve 6 is a solenoid valve. The dual-control temperature relay 4 is connected to the pump 5 and the solenoid valve 6 through a low temperature contact and a high temperature contact respectively.

[0016] In order to ensure that the water heater 1 can produce hot water, the dual-control temperature relay 4 is electrically connected to the pump 5 through the low temperature contact when the water temperature ...

Abstract

The invention relates to a water heating device, in particular to a water heater. An instant on-and-use device of the water heater comprises a hot water outlet pipe, a cold water inlet pipe, a return pipe communicating the hot water outlet pipe and the cold water inlet pipe, and an outlet valve; a pump is arranged on the return pipe; the device also comprises a double control temperature relay; and the outlet valve is an electromagnetic valve. The device not only can meet the requirement of people on water yield, but also saves electrical power.

Description

technical field [0001] The invention relates to a water heating device, in particular to a water heater. Background technique [0002] At present, commercially available water heaters are mainly divided into gas type and electric type. Regardless of the type of water heater, there is cold water stored in the pipe connected between the water heater and the faucet. Big, if the temperature in the bathroom is too low, the bather is prone to catch cold and get sick, which has become a difficult problem in the lives of ordinary people. Through research on water heaters, we found that the cold water flowing out before using hot water comes from two parts. The required water temperature is already flowing out of the water outlet. This results in unnecessary waste. Therefore, there is an urgent need for an instant water heater. [0003] In order to solve this problem, electric water heater manufacturers have introduced various instant water heaters. This kind of water heater is ...
