Description

Technical Field

[0001] This utility model relates to the field of electric water heater technology, and in particular to an electric water heater anti-electric shock wall safety detector. Background Technology

[0002] When the heating element of an electric water heater is damaged and leaks electricity, after replacing the heating element, it is necessary to check whether the water heater's anti-electric shock wall has been broken down and leaking electricity. Traditional anti-electric shock wall testing requires removing the anti-electric shock wall from the water heater and then using a multimeter for auxiliary testing. Testing the anti-electric shock wall with a multimeter is time-consuming, laborious, and unsafe, and is estimated to take 1 hour. Therefore, there is an urgent need for an electric water heater anti-electric shock wall safety tester that can complete the test quickly without removing the anti-electric shock wall. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies where testing the anti-electric shock wall requires removing it from the water heater and then using a multimeter for testing, which is time-consuming, laborious, and unsafe. This invention provides a safety tester for the anti-electric shock wall of an electric water heater.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] An electric water heater anti-electric shock wall safety tester, comprising:

[0006] Power plug, used to connect to an external power source;

[0007] The motherboard is housed inside the casing, and the power plug is connected to an external power source to supply power to the motherboard.

[0008] A three-hole socket is electrically connected to the main board and is located inside the housing. The housing has three corresponding through holes for connecting the plug of the electric water heater.

[0009] A leakage current detection module, which is electrically connected to the main board, is used to detect the current of the water heater's anti-electric shock wall and determine whether the current exceeds a threshold.

[0010] An alarm module electrically connected to the leakage detection module is used to trigger an alarm after detecting that the leakage current of the water heater's anti-electric shock wall exceeds a threshold.

[0011] As a preferred embodiment of this utility model, the leakage current detection module includes a current acquisition unit and a current processing unit that are electrically connected:

[0012] The current acquisition unit includes a test probe interface on the motherboard, and a corresponding through hole is provided on the housing for connecting an external test probe. The test probe is used to detect the current of the threaded iron part of the hot water outlet of the electric water heater.

[0013] The current processing unit is disposed inside the housing and is used to determine whether the current exceeds a threshold.

[0014] As a preferred embodiment of this utility model, the current processing unit is a relay electromagnetic coil. When the current exceeds a preset value, the relay electromagnetic coil is activated, triggering the alarm module to sound an alarm.

[0015] As a preferred embodiment of this utility model, the alarm module is disposed on the surface of the housing.

[0016] As a preferred embodiment of this utility model, the alarm module is a buzzer.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] The equipment is easy to operate, stable, and low in cost. It eliminates the need to remove the anti-electric shock wall from the water heater and use a multimeter for testing, greatly shortening the testing time and improving safety.
