DETAILED DESCRIPTION

[0044] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments.

It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0046] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0047] In the description of the embodiments of the present application, it should be understood that the terms "inside", "outside", "top", "bottom", "front", "back", etc. indicating the orientation or position relationship (if any) are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0048] Existing household water heaters are usually wall-mounted water heaters, which include a body and an inlet and outlet pipe. The body is connected to the pipe system in the wall through the inlet and outlet pipes. In order to facilitate the control of water flow, valves are set on the inlet and outlet pipes between the body and the wall. In order to protect the valve and prevent the valve from being triggered by mistake, a protective cover is usually set on the inlet and outlet pipes to protect and hide the valve. The protective cover also plays the role of hiding the inlet and outlet pipes, making the room look neater.

[0049] However, although installing the hidden cover plays a protective and concealing role, when the water heater needs to be repaired, the valve must be used to operate the water flow. At this time, the hidden cover needs to be removed for operation, which reduces the maintenance efficiency.

[0050] Therefore, in response to the above problems, the present application proposes a pipe protection structure and a water heater that can protect the connected water pipes and facilitate maintenance. The present application will be further explained in conjunction with the accompanying drawings.

[0053] A pipeline protection structure provided in the present application is applied to a connecting pipeline between a water heater and a wall. A valve is arranged on the connecting pipeline. The pipeline protection structure includes a cover assembly. The cover assembly is arranged between the water heater and the wall. A retractable cover of the cover assembly is arranged outside the connecting pipeline.

[0054] By arranging a pipeline protection structure around the outside of the connecting pipeline, the cover assembly in the pipeline protection structure is extended and retracted to cover and expose the valve, thereby realizing valve maintenance and improving maintenance efficiency.

[0055] like Figure 1 and Figure 2 As shown, a water heater with a pipeline protection structure provided in the present application is applied to a connecting pipeline 300 between the water heater and a wall 200, a valve 310 is arranged on the connecting pipeline 300, and the pipeline protection structure includes a cover assembly, the cover assembly includes a first protective cover 400 and a second protective cover 500, the first protective cover 400 and the second protective cover 500 are both covered on the connecting pipeline 300, one end of the first protective cover 400 is used to connect to the water heater, one end of the second protective cover 500 is used to connect to the wall 200, and the other end of the first protective cover 400 is connected to the other end of the second protective cover 500.

[0056] The second protection cover 500 is configured to be retracted relative to the first protection cover 400 to abut against or disengage from the first protection cover 400 , thereby covering or exposing the valve 310 .

[0057] The first protective cover 400 and the second protective cover 500 jointly protect the connecting pipeline 300, and the valve 310 can be directly controlled by the retractable second protective cover 500 without removing the first protective cover 400 and the second protective cover 500, thereby improving the maintenance efficiency of the water heater.

[0058] The connecting pipeline 300 in this embodiment includes a water outlet pipe and a water inlet pipe. Both the water outlet pipe and the water inlet pipe are provided with valves 310. Both valves 310 are close to the wall 200 and are angle valves.
