Problems solved by technology

This has great limitations, because the power of the civilian electric meters equipped with domestic residents is generally single-phase 20A, which cannot withstand such a large power
And if the power is reduced, the amount of hot water will be reduced, which cannot meet the needs of consumers.

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] see Figure 1-Figure 2 , The instant heating electric water heater includes a shell 1 and an inner tank 2, and the inner tank 2 is provided with a heating element 7 and an outlet pipe 3. The outlet pipe 3 is provided with a second water inlet 3.1 corresponding to the top of the inner tank 2, and the distance between the second water inlet 3.1 and the top of the inner tank 2 should not be greater than 2CM-3CM, so as to realize the anti-dry function and improve the safety of the product. Security and Stability. The lower part of the water outlet pipe 3 is provided with a second water outlet hole 3.2 which communicates with the second water inlet hole 3.1. The heating element 7 is fixed on the bottom of the inner container 2, and the terminal of the heating element 7 passes through the inner container 2, and is electrically connected with the powe...

Abstract

A fast-heating electric water heater, including a shell and an inner tank, a heating element is arranged on the inner tank, a turbine heating part is arranged on the periphery of the heating element, and a gap is arranged between the turbine heating part and the heating element, and a heating chamber is jointly formed ; A heat exchange tube is arranged in the water storage chamber of the inner tank, and the heat exchange tube is in a spiral shape, which communicates with the water supply component. The invention has the characteristics of simple and reasonable structure, low cost, wide application range and safe and reliable use; the spiral heat exchange tube can allow tap water to flow in the pipeline along the spiral direction under the action of hydraulic pressure, and enter the inner tank. The hot water in the tank can preheat the cold water through the heat exchange tube, which is beneficial to improve the thermal efficiency and save the heating time; The water can be quickly heated to the required temperature in a short time, thereby saving energy, reducing the temperature difference between the top and bottom of the inner tank, and avoiding the phenomenon of hot and cold water temperature.

Description

technical field [0001] The invention relates to an electric water heater, in particular to a fast-heating electric water heater. Background technique [0002] At present, electric water heaters can be divided into the following two categories: one is storage-type electric water heaters, which are filled with water in the storage tank when in use, and after the preheating water temperature reaches the set temperature, the water mixing valve is used to adjust the water outlet with cold water. Electric water heater for bathing. The storage type electric water heater has the advantages of safety, environmental protection, low installation line requirements and limited influence. However, due to its long warm-up time and slow heating, it takes a long time to wait; and the amount of water is limited, often there is no hot water in the middle of the bath, or the hot water is found to be insufficient in the middle of the bath; the water temperature is unstable, and the water temper...
