Abstract

This utility model provides a water heater for a travel vehicle, comprising: a protective shell (11), a base plate (12), and a protective shell cover (13) forming an outer cover (1) with a hollow cavity. The base plate (12) is located at the bottom of the protective shell (11), and the protective shell cover (13) is located at the top of the protective shell (11). A furnace cover (2) and a water tank (3) are sequentially arranged between the base plate (12) and the protective shell cover (13) within the hollow cavity of the outer cover (1). Multiple arc-shaped tubes (31) are arranged inside the water tank (3). The air inlet end (311) and the air outlet end (312) of each arc-shaped tube (31) are welded and fixed to the bottom of the curved surface of the water tank (3). The air inlet end (311) is fitted inside the furnace cover (2), and the air outlet end (312) is fitted outside the furnace cover (2). This utility model can effectively solve the problem of inconvenience in selecting the opening position and cutting the opening process when installing a water heater.
