Embodiment Construction

[0018] Such as figure 1 As shown, the instant electric water heater of the present invention includes a heater 1, a cold water inlet 2 connected to both ends of the heater 1 and a hot water outlet 3, and the hot water outlet 3 is connected with a shower head or a shower 8. A branch 4 connected in parallel with the heater 1 is set between the cold water inlet 2 and the hot water outlet 3, and a solenoid valve 5 is installed in the branch, and the signal input terminal of the control drive circuit of the solenoid valve 5 is connected with the temperature sensor 6 is connected with flow sensor 7. The temperature sensor 6 for measuring the temperature of the water outlet of the heater and the flow sensor 7 for measuring the flow rate of the water inlet are controlled on and off by the control driving circuit of the solenoid valve 5 .

[0019] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

Abstract

The invention provides an instant electric water heater, which comprises a heater (1), a cool water inlet (2) and a hot water outlet (3) connected to both ends of the heater (1). A branch (4) connected in parallel with the heater (1) is arranged between the cool water inlet (2) and the hot water outlet (3). A solenoid valve (5) is arranged in the parallel branch (4). A signal input end of the solenoid valve (5) for controlling a drive circuit is connected with a temperature sensor (6) for measuring the water temperature in the heater (1). The on / off of the solenoid valve (5) in the parallel branch (4) is controlled through the temperature sensor (6), so that high-temperature water which is heated for a short time in the heater is mixed with cold water in the parallel branch and then the mixed water is discharged when hot water is used again so as to ensure that instant high temperature of outlet water cannot occur.

Description

technical field [0001] The invention relates to an instant electric water heater, in particular to a constant temperature instant electric water heater. Background technique [0002] Instantaneous electric water heaters use electric heating rods or electric heaters to heat the water flowing through them. When the water outlet is temporarily closed during use, the water remaining in the heater will be heated to a higher temperature for a short time, usually 10°C higher than the set water temperature. Therefore, when the hot water is turned on again, the user will feel that a section of water flow is hotter, and even cause burns in severe cases. At this time, the user often takes the method of allowing the hot water to flow for a while when turning on the hot water again, and continues to shower after the water temperature returns to normal. This results in a waste of water and energy. [0003] Utility model ZL200420073895.3 discloses a constant temperature gas water heater...
