Problems solved by technology

These methods have the disadvantages of difficult processing, high cost, serious pollution, time-consuming and labor-intensive work, high labor intensity and affecting normal work, and it is difficult to achieve the ideal purpose of scale inhibition and descaling
[0004] Currently commonly used electric heating elements for water boilers, especially special electric heating elements such as special ceramics, if the fouling phenomenon is serious, it will seriously affect the performance and life of the electric heating elements
In the prior art, the ultrasonic descaling is mainly applied in the boiler pipes, the purpose is to avoid the blockage of the boiler pipes, and the direct application to the boiler body has not been reported; seldom used in practice

Embodiment 1

[0038] The structure of the boiler is as Figure 1-3 As shown, among them, the electric heating element 2 is made of ceramic electric heating element, which is made by wrapping resistance wire with ceramic material, forming, hot pressing sintering and mechanical processing; it can withstand high temperature of 1300°C. The ultrasonic generator 3 selects a 20kHz, 1000W ultrasonic generator, which continuously acts on 20L of water within 20 minutes. The water discharged from the faucet 4 is boiled water, and the temperature reaches 95°C. It takes 3 minutes to boil the water when the whole water boiler is running for the first time. After boiling, the power is not turned off, and boiling water is provided at any time. In order to check the effect, the water is connected to detect the change of the water after 20 minutes of ultrasonic operation. Through the detection of 500MHz nuclear magnetic resonance spectrometer, it is shown that the half-peak width of oxygen in water molecules...

Embodiment 2

[0041] The structure of the boiler is as Figure 1-3 As shown, among them, the electric heating element 2 is made of ceramic electric heating element, which is made by wrapping resistance wire with ceramic material, forming, hot pressing sintering and mechanical processing; it can withstand high temperature of 1300°C. The ultrasonic generator 3 selects a 30kHz, 700W ultrasonic generator, which continuously acts on 20L of water within 20 minutes. The water released from the faucet 4 is boiled water, and the temperature reaches 95°C. It takes 3 minutes to boil the water when the whole water boiler is running for the first time. After boiling, the power is not turned off, and boiling water is provided at any time. In order to check the effect, the water is connected to detect the change of the water after 20 minutes of ultrasonic operation. The detection by 500MHz nuclear magnetic resonance spectrometer shows that the half width of oxygen in water molecules is reduced from 125.86...

Embodiment 3

[0044] The structure of the boiler is as Figure 1-3 As shown, among them, the electric heating element 2 is made of ceramic electric heating element, which is made by wrapping resistance wire with ceramic material, forming, hot pressing sintering and mechanical processing; it can withstand high temperature of 1300°C. The ultrasonic generator 3 selects a 40kHz, 200W ultrasonic generator, which continuously acts on 20L of water within 20 minutes. The water released from the faucet 4 is boiled water, and the temperature reaches 95°C. It takes 3 minutes to boil the water when the whole water boiler is running for the first time. After boiling, the power is not turned off, and boiling water is provided at any time. In order to check the effect, the water is connected to detect the change of the water after 20 minutes of ultrasonic operation. Show by nuclear magnetic detection, the half peak width of the oxygen in the water molecule is reduced to 102.41MHZ by 125.86MHZ, compared wi...

Abstract

The invention discloses a water boiling device, which comprises a water tank, an electric heating element, ultrasonic generators, a high-water level probe, a low-water level probe, a temperature controller, a faucet, a water inlet, a drain outlet, an exhaust hole, a controller and a support, wherein the water tank has a hollow structure made of stainless steel or aluminum alloy and is arranged on the support; one ultrasonic generator is arranged on the wall of the water tank and extends into a water body, or a plurality of ultrasonic generators are distributed on the outer wall of the water tank; the ultrasonic generators transmit ultrasonic waves with the frequency of between 20 and 40kHz and the power of between 200 and 1,000W; and the electric heating element is fixed on the water tank. According to the water boiling device, energy generated by the ultrasonic generators is transferred to 12 water molecular groups, so that the water molecular groups are converted into small micro (small) water molecular groups; the water boiling device is descaled by utilizing the ultrasonic waves; and after the water boiling device runs for 15 days, a scaling layer on the boundary surface of the electric heating element is only 0.001 millimeters, and the middle part of the electric heating element is still kept smooth, so the aims of scale prevention and descaling are well fulfilled.

Description

technical field [0001] The invention relates to a water boiler, in particular to a water boiler which utilizes a high-power electric heating element for heating and an ultrasonic generator, and has the functions of energy transmission, scale inhibition, scale removal, and water quality improvement, and is suitable for water quality requirements. High-power group fast-heating water boiler with high efficiency and short drinking cycle. Background technique [0002] At present, during the working process of the water boiler, due to the presence of mineral salts in the water, when the water temperature reaches about 80°C, crystals begin to form. and containers, etc., forming dirt. The formation and accumulation of dirt will lead to serious corrosion of the container; the heat transfer efficiency of the electric heating element is reduced, the internal heat is difficult to transfer to the water, and the temperature rises sharply, which in turn affects the service life and workin...
