Specifically, the water heater can be an electric heater or a heat pump water heater and other entities, and the functions of the water heater are increased by arranging the decorative cover for the water heater, so that the requirement of a user on sterilization treatment of air in a toilet space in a bathing process is met.

In another embodiment of the present application, the water heater further includes a water leakage preventing device including:

the water pipe comprises a first water pipe 100, wherein the first water pipe 100 is provided with a first water inlet pipe head 101, a first pipe head 102 and a first water outlet pipe head 103, a first connecting flow passage 104 is further arranged in the first water pipe 100, a first port of the first connecting flow passage 104 is communicated with the first water inlet pipe head 101, and a second port of the first connecting flow passage 104 is communicated with the first water outlet pipe head 103;

the second water pipe 200 is provided with a second water inlet pipe head 201, a second connecting pipe head 202 and a second water outlet pipe head 203 which are mutually communicated, the second water inlet pipe head 201 is provided with a one-way valve 208, and the one-way valve is used for controlling water flow to flow into the second water pipe 200 from the second water inlet pipe head 201 in a one-way mode;

a pressure on-off valve 300, the pressure on-off valve 300 being provided in the first connector head 102 and being used to switch the second port of the first connection flow path 104 according to the water pressure at the first connector head 102;

and a connection tube 400, the connection tube 400 being connected between the first connector head 102 and the second connector head 202.

Specifically, the water leakage prevention device provided by the embodiment of the application is used for being installed on a water heater in a user home to perform water leakage prevention protection on the water heater.

The water leakage preventing apparatus mainly includes a first water pipe 100, a second water pipe 200, a pressure on-off valve 300, and a connection pipe 400.

The first water pipe 100 is provided with a first water inlet pipe head 101 for connecting with an external water supply pipe to introduce tap water into a municipal pipe network, and a first water outlet pipe head 103 of the first water pipe 100 is connected with a water inlet pipe 5 of a water heater in a user's home to convey the tap water into the water heater.

The second water inlet pipe head 201 of the second water pipe 200 is used for connecting with the water outlet pipe 6 of the water heater, so that the water treated by the water heater is output. The second outlet pipe head 203 of the second water pipe 200 is connected with a water using terminal in the home of the user to realize the final output of water.

The first and second water pipes 100 and 200 are connected to each other by a connection pipe 400, so that the first and second connector heads are connected to each other.

The pressure on/off valve 300 of the first connector can perform a corresponding operation according to a pressure generated between the water pressure in the first connector and the second port of the first connection flow path 104, thereby preventing water leakage.

In the using process, in general, the conventional water heater is provided with two external connectors for connecting external water pipes, when the water heater is installed, the first water outlet pipe head 103 is connected with one external connector of the water heater, and the second water inlet pipe head 201 is connected with the other external connector of the water heater.

In the process that the user used water through the water end, the second water pipe 200 then passed through this moment the second outlet pipe is connected with the water end and is upwards exported water, and at this moment, the water pressure in the second water pipe 200 is compared in the water pressure reduction that first water inlet pipe head 101 goes out, and meanwhile, first connector owing to through connecting pipe 400 with the second connector intercommunication, and then make the water pressure of first connector department also correspondingly reduces. The water introduced from the first inlet pipe head 101 is outputted through the second top opening pressure on/off valve 300 of the first connection flow passage 104 and finally flows into the water heater through the first outlet pipe head 103.

After the user closes the water use terminal, since the tap water pressure of the external water supply pipe is transferred to the second water pipe 200, and the water pressure of the first connector is gradually increased and finally identical to the water pressure of the first water inlet connector 101, the pressure on-off valve 300 is automatically reset to close the second port of the first connection flow passage 104.

At this time, if the water heater is broken and leaks water, since the second water inlet pipe head 201 of the second pipe body is provided with the check valve, the water end leaks, the change of the water pressure in the second pipe body is not caused, and the pressure on-off valve 300 is always in a state of closing the second port of the first connection flow channel 104, and finally, the serious leakage caused by inputting tap water into the water heater under the condition that the inside of the water heater is damaged is avoided.

Through dispose the pressure on-off valve in first water pipe, the pressure on-off valve is built-in first water pipe completely, first water pipe is connected through first water pipe head and delivery pipe (water pipe) in the user's house, first water pipe and second water pipe are installed respectively on the water heater in the user's house, the water heater is under the user state, the water that first water pipe introduced is exported from the second water pipe after the water heater is handled, at this moment, because first connecting pipe head of connecting pipe intercommunication and second connecting pipe head, the water pressure in the first connecting pipe head is less than the water pressure in the first water pipe head, at this moment, the pressure on-off valve then opens the port two of first connecting runner to make first water pipe head and first water pipe head communicate and realize supplying water. When the water heater is in a water-off state, the water pressures in the first water pipe and the second water pipe are gradually the same, so that the water pressures in the first water inlet pipe head and the first connecting pipe head are balanced, and at the moment, the pressure on-off valve automatically resets and closes the second port of the first connecting flow passage; under the inside condition that takes place to leak at the water heater, because the second water pipe head that intakes is provided with the check valve for the water pressure in first water pipe head and the first connector still maintains balanced state, and then ensures that the delivery pipe can not follow the outside output water of first water pipe, realizes reducing the use reliability that takes place to leak the accident in order to improve electrical apparatus.
