Problems solved by technology

[0002] Electric water heaters have the risk of electric shock caused by electric leakage during use, especially after the electric water heater has been used for a long time and the components are aging, its heating parts are particularly prone to aging and damage, resulting in electric leakage. Although most of the existing electric water heaters use various electric leakage The detection module is used to detect and warn the leakage situation, but in the actual use process, there will be defects such as inconvenience in use, passive detection that cannot be actively prevented, or aging failure of the leakage detection module itself, which cannot meet the needs of use.

Embodiment 1

[0031] Please refer to figure 1 with figure 2 As shown, this embodiment provides an electric water heater anti-shock device 001, which is used in conjunction with an electric water heater to prevent electric shock during use. The electric water heater anti-shock device 001 includes a controller and a water outlet pipe installed in the electric water heater The normally-closed first solenoid valve 110 on 100 and the water immersion sensor 120 arranged in the water outlet pipe 100. The water sensor 120 and the first solenoid valve 110 are arranged in sequence along the direction of water outlet in the water outlet pipe 100. The heating device 240, the first solenoid valve 110, and the water immersion sensor 120 of the water heater are electrically connected. When the water immersion sensor 120 detects water passing through, the signal is transmitted to the controller, and the controller sequentially controls the heating device 240 to close and the first solenoid valve 110 is open...

Embodiment 2

[0034] Such as image 3 with Figure 4 As shown, this embodiment provides an electric water heater 002, which includes a water heater body 200 having a first inner tank 210 and the above electric water heater anti-shock device 001. The water heater body 200 also includes a water outlet pipe 100 connected to the first inner tank 210 And a heating device 240 for heating the water in the first inner container 210, the heating device 240 is a heating tube.

[0035] The electric water heater anti-shock device 001 includes a controller, a normally closed first solenoid valve 110 installed on the outlet pipe 100, and a water immersion sensor 120 arranged in the outlet pipe 100. The water immersion sensor 120 and the first solenoid valve 110 extend along The directions of the water outlet in the water pipe 100 are arranged in sequence, and the controller is electrically connected to the heating device 240 of the electric water heater, the first solenoid valve 110, and the flood sensor 12...

Abstract

The invention discloses an electric shock preventing device for an electric water heater and the electric water heater and belongs to the field of electric water heaters. The electric shock preventingdevice for the electric water heater comprises a controller, a first electromagnetic valve installed on a water outflow pipe of the electric water heater and a water logging sensor arranged in the water outflow pipe; the water logging sensor and the first electromagnetic valve are sequentially arranged in the water outflow direction in the water outflow pipe; the controller is electrically connected with a heating device of the electric water heater, the first electromagnetic vale and the water logging sensor; and when the water logging sensor detects passing of water, a signal is transmittedto the controller, and the controller sequentially controls closing of the heating device and opening of the first electromagnetic valve. The electric shock preventing device for the electric water heater can effectively avoid the electric shock danger of the electric water heater in the using process, and the using safety is improved. The invention further provides the electric water heater containing the electric shock preventing device for the electric water heater.

Description

Technical field [0001] The invention relates to the field of electric water heaters, and in particular to an electric shock prevention device and an electric water heater. Background technique [0002] Electric water heaters have the risk of electric shock caused by leakage during use. Especially when the components of the electric water heater are aging for a long time, the heating parts of the electric water heater are especially susceptible to aging and damage to cause leakage. Although most of the existing electric water heaters use various types of leakage The detection module is used to detect and warn the leakage situation, but in actual use, it is still inconvenient to use, passive detection cannot be actively prevented, or the leakage detection module itself is aging, which cannot meet the needs of use. Summary of the invention [0003] The object of the present invention is to provide an electric water heater anti-shock device, which can effectively avoid the electric sh...
