The invention provides a rotary knob assembly with a sealing function and a water heater. The rotary knob assembly comprises a rotary knob, a display shell and a sealing piece, wherein a sealing ringis arranged on the display shell, a mounting hole is formed in the middle of the sealing ring, the rotary knob is buckled on the sealing ring, the rotary knob is connected with a rotating shaft in thedisplay shell through the mounting hole, and the sealing piece is arranged between the inner surface of the rotary knob and the outer surface of the sealing ring. According to the rotary knob assembly with the sealing function and the water heater provided by the invention, the gap between the rotary knob and the display shell is sealed by the sealing piece, so that the problem that in the priorart, due to the existence of the gap, moisture enters the interior of the display shell to influence the normal operation of an electrical element is solved, the relative positions of the sealing piece can be limited by convex ribs and annular recesses, the reliability of the sealing piece is guaranteed, the sealing effect can be increased by the elasticity of a silicon rubber material, and the hand feeling of a user is increased.
Description
technical field [0001] The invention relates to the technical field of control button assemblies, in particular to a knob assembly with a sealing function and a water heater. Background technique [0002] Gas water heaters with knobs are currently on the market with no seal or poor seal between the knob and the panel, which will cause rainwater to enter the casing after the water heater encounters rain and cause damage to the internal components of the casing. If rainwater invades electrical components, it will cause damage to the electrical appliances Disconnection, damage and other consequences. Contents of the invention [0003] In order to solve technical problems such as short circuit caused by water vapor infiltrating through the gap between the knob and the panel, a knob assembly and a water heater with sealing function for sealing the gap formed at the knob are provided. [0004] A knob assembly, comprising a knob, a display case and a seal, the display case is pr...
