Water heater with function of self-cleaning water scales on insulating inner container and heating rods

Abstract

The invention discloses a water heater with the function of self-cleaning water scales on an insulating inner container and heating rods. The water heater comprises a shell and the insulating inner container arranged in the shell, and the two heating rods are horizontally installed on the inner side wall of the insulating inner container; a circular cavity is formed in the side wall of the shell;a ball screw is coaxially and rotatably connected to the inner wall of the insulating inner container, and the right end of the ball screw sequentially penetrates through the insulating inner container and the shell and is rotatably connected to the inner wall of the circular cavity; the joint of the ball screw and the insulating inner container is connected in a rotating and sealing mode; the side wall of the portion, located in the circular cavity, of the ball screw is fixedly sleeved with a rotating cylinder; a heat transfer base is fixedly connected to the inner bottom of the circular cavity; and multiple electromagnet brush pieces are arranged on the side wall of the rotating cylinder at equal distance in the circumferential direction of the rotating cylinder. According to the water heater, the conception is novel, the water scales on the surfaces of the insulating inner container and the heating rods of the water heater can be removed after water is heated by the water heater every time, and therefore the heating efficiency and the insulating effect of the water heater are guaranteed.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a water heater with the function of self-clearing the scale of the heat preservation tank and the heating rod. Background technique [0002] The existing electric water heater is to place the electric heating tube in the water tank to directly heat the cold water in the water tank. The disadvantage is that after a period of use, the heat exchange efficiency between the electric heating tube and the water in the water tank is greatly reduced and the heat preservation effect of the water tank It is greatly reduced, and may even burn the electric heating tube; the reason is that the impurities in the tap water become scales and accumulate on the surface of the electric heating tube and the inner wall of the insulation liner after being heated. The heat exchange efficiency between water and water, when the scale is too thick, the electric heating tube will burn out the heating ...

[0002] The existing electric water heater is to place the electric heating tube in the water tank to directly heat the cold water in the water tank. The disadvantage is that after a period of use, the heat exchange efficiency between the electric heating tube and the water in the water tank is greatly reduced and the heat preservation effect of the water tank It is greatly reduced, and may even burn the electric heating tube; the reason is that the impurities in the tap water become scales and accumulate on the surface of the electric heating tube and the inner wall of the insulation liner after being heated. The heat exchange efficiency between water and water, when the scale is too thick, the electric heating tube will burn out the heating wire because the internal heat cannot be dissipated in time, which shortens the service life of the electric heating tube and the water tank, and wastes resources
