Abstract
Disclosed is an automatic constant-temperature secondary temperature raising and capacity increasing electric water heater which comprises a shell, a water storage tank, an electric heater, a control device and a water mixing valve. The electric water heater further comprises an instantaneous heat exchanger. The water inlet end of the instantaneous heat exchanger is communicated with a water inlet pipe, and the water outlet end is connected with the other water inlet port of the water mixing valve. The instantaneous heat exchanger works alternately with the electric heater of a hot water storage tank. Due to the adoption of the above structure, the electric water heater has the following characteristics: 1. the electric heater in the water storage tank carries out heating, and hot water flowing out of the water storage tank is mixed with cold water in a water channel of the instantaneous heat exchanger; 2. preheating is first carried out in the water storage tank, then the instantaneous heat exchanger works, and water flowing out of the water storage tank and the instantaneous heat exchanger is mixed together; 3. either the electric heater of the water storage tank or the instantaneous heat exchanger separately works, and hot water flowing out of the water mixing valve is used for bathing. Due to alternate working between the electric heater and the instantaneous heat exchanger, the electric water heater achieves the purposes of saving electric energy, multiplying hot water and maintaining constant temperature.

Description of drawings
Fig. 1 is a front view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
A kind of as shown in Figure 1 automatic constant-temperature secondary capacity-increasing type electric heater of heating, comprise shell 1, storage tank 2, electric heater 3, control device and mixed water valve 4, blow-off pipe 21, water inlet pipe 22 and hot water outlet pipe 23 are arranged on the storage tank 2, be provided with water storage temperature sensor 2A in the storage tank 2, water storage temperature sensor 2A is arranged in the storage tank 2 by a safe sleeve pipe 5; On the water outlet interface of mixed water valve 4 mixing water temperature sensor 4C is set, hot water outlet pipe 23 is connected with a water inlet interface of mixed water valve 4; Also comprise an Instant heating type heat exchanger 6.
The water inlet end of described Instant heating type heat exchanger 6 is communicated with water inlet pipe 22, its water side is connected with another water inlet interface of mixed water valve 4; Instant heating type heat exchanger 6 and electric heater 3 alternations.
Instant heating type heat exchanger 6 be provided with cold water, hot water sensor 6A, 6B into and out of water end (W.E.).
Hot water outlet pipe 23 is provided with inflow temperature sensor 4B with the water inlet interface of mixed water valve 4.Instant heating type heat exchanger 6 is provided with inflow temperature sensor 4A with the water inlet interface of mixed water valve 4.
The utility model in use, after the start energising, electric heater 3 in the storage tank 2 (power≤5KW) begin to heat, (preheating water temperature control rule: adjust automatically when storage tank inner storing water temperature sensor 2A detects water temperature in the storage tank 2 and reaches 60～75 ℃ of the preheat temperatures of setting according to inflow temperature, when inflow temperature≤10 ℃, 75 ℃ of pre-heat setting temperatures; When inflow temperature＞10 ℃≤25 ℃, 60 ℃ of pre-heat setting temperatures; When inflow temperature＞25 ℃, preheating water one-level heater 3 does not start.), electric heater 3 stops heating.At this moment, open the water outlet master switch, Instant heating type heat exchanger 6 (power≤5KW) start working.When Instant heating type heat exchanger 6 break-ofves, electric heater 3 starts heating immediately, unless the water temperatures in the storage tank 2 quit work when reaching aforementioned preheating water temperature control rule request automatically.
