Embodiment 1

[0041] figure 1 A schematic structural view of the water heater of this embodiment is given. As shown in the figure, the water heater includes a controller, an inner tank 1 and a heater 2 installed in the inner tank 1 through a flange. The inner tank 1 includes a tank body 12 in the middle and sealing heads 11 on the left and right sides, close to the heater 2 The lower part of the fan 3 is provided with a fan 3, and the fan 3 is fixed on the right side head 11 of the liner 1. Such as figure 2 As shown, the fan 3 includes a motor 31, a housing 32 and a fan blade 33 arranged inside the housing 32. The housing 32 is provided with two inflow holes 34, and the water outlet of the housing 32 is connected to the heater 2. Relatively, the water in the water heater can quickly flow into the housing 32 of the fan 3, the controller controls the starting motor 31, the motor 31 drives the fan blade 33 to rotate, and the fan blade 33 disturbs the water flow around it, thereby driving th...

Embodiment 2

[0045] Such as Figure 5 As shown, the basic structure of this embodiment is the same as the first embodiment, including a controller, an inner tank 1 and a heater 2 installed in the inner tank 1 through a flange, and a fan 3 is arranged near the lower part of the heater 2 . The difference from the first embodiment is that the heater 2 is further provided with a temperature sensor 5 for detecting the temperature of the heater 2 .

[0046] Its working process is similar to the first embodiment, the difference is that the disturbance temperature T is preset in the controller, the heater temperature detected by the temperature sensor is t, and the temperature sensor transmits the detected t value to the controller, when t≥ When T, the controller controls the fan to continue to rotate or alternately performs the spoiler segment and the intermittent segment; when t<T, the controller controls the fan to stop working. The turbulence temperature T can be selected and set according to...

Embodiment 3

[0049] Such as Figure 6As shown, the basic structure of this embodiment is the same as that of the first embodiment, including a controller, an inner tank 1 and a heater 2 installed in the inner tank 1 through a flange. The difference from Embodiment 1 is that a vibrator 6 is provided near the lower part of the heater 2, and the controller controls the vibration of the vibrator 6 to disturb the water flow in the area where the heater 2 is located to drive the scale movement in the water flow , so as to avoid scale deposition on the surface of the heater. Using a vibrator instead of the fan in Embodiment 1 can also achieve the effect of delaying the fouling of the heater.

Abstract

The invention discloses a heater body scaling delaying method and a water heater and aims to solve the problem that the heater body surface of an existing water heater is prone to scaling. The method includes producing disturbance to drive the water scale to move in the flow of the region where the heater body located, and avoiding the scale accumulation on the heater body surface. The water heater comprises a controller, a cylinder and a heater body installed in the cylinder; at least one flow drive device is arranged in the cylinder adjacent to the heater body; the water heater controls the at least one flow drive device to produce continuous or intermittent disturbance to drive the scales of the flow to move in the flow of the region where the heater body located through the controller, and the scale is prevented from accumulating on the heater body surface. The water heater is capable of delaying heater body scaling and saving energy and is simple and reliable in structure.

Description

technical field [0001] The invention relates to a method for delaying fouling of a heater and a water heater for realizing the method. Background technique [0002] Scale formation is currently the main problem plaguing the water heater industry. For storage-type electric water heaters, the cause of scale formation is that during the heating process, the water flow has no external force except for the natural movement caused by heating, and this natural movement is very slow. The sediment precipitated during the heating process will slowly accumulate on the surface of the inner tank and the heater, and over time, it will become scale. Because scale is mainly produced on the heating surface, and in water heaters, generally only the surface of the heater is the heating surface with high heat load, so scale is mainly formed on the surface of the heater. [0003] The scale deposition has many harms to the water heater: 1) The thermal conductivity of the scale is very poor, and ...
