Problems solved by technology

But obviously this scheme is more complicated and will increase the manufacturing and control costs of electric water heaters
Another solution is found in the patent application with the application number CN01235470.8. Its idea is to adopt double heating devices arranged up and down, so as to use the stratification phenomenon of water temperature to obtain different amounts of hot water through separate or simultaneous heating. This solution It is relatively simple, easy to implement, and has certain application value, but the ability to regulate the amount of hot water is limited, and it is difficult to meet the regulation needs of various hot water amounts.

Embodiment 1

[0019] The energy-saving variable capacity electric water heater of the present embodiment is as figure 1 Shown, the bottom of liner 1 is equipped with water inlet pipe 2 and water outlet pipe 3, and electric heating rod 4 is equipped with on the side. Outlet pipe 3 wherein is made up of the outer tube 3-1 that is fixed on the inner tank wall by sealing member and the inner tube 3-2 that is inserted in the outer tube, as figure 2 As shown, the outer pipe wall is shaped on a group of overflow holes 3-3 with different heights, and the inner pipe wall has a group of through holes 3-4 corresponding to the height of each overflow hole of the outer pipe, and each overflow hole 3-3 of the outer pipe 3 is relatively staggered with the angular position of each through hole 3-4 of the inner pipe. Two commonly used staggering methods, one is that the overflow holes 3-3 of different heights on the outer pipe wall are located on the same bus, and the through holes 3-4 of the inner pipe w...

Embodiment 2

[0024] The basic structure of the energy-saving variable capacity electric water heater of this embodiment is the same as that of Embodiment 1, and the differences are as follows: image 3 As shown, the outer pipe wall is formed with an overflow groove 3-3 from top to bottom, and the inner pipe wall is provided with a through groove 3-4 corresponding to the height of the outer pipe overflow groove, and the outer pipe overflow groove and the inner pipe through groove The angular positions are relatively staggered. Two commonly used ways of staggering, one is that the overflow groove 3-3 from top to bottom on the outer pipe wall is located on the same busbar, and the inner pipe wall through groove 3-4 is spiral in angular dislocation; the other is that the outer pipe wall The overflow hole 3-3 from top to bottom is in a spiral shape with angular dislocation, and the through groove 3-4 on the inner pipe wall is located on the same generatrix.

Embodiment 3

[0027] The overall structure of the energy-saving variable capacity electric water heater of this embodiment is similar to that of Embodiment 1, except that there are two water outlet pipes, one high and one low, and the lower ends of the two water outlet pipes intersect in a Y shape, and a switching valve 8 is provided at the intersection. When it is necessary to adjust the effective volume of the electric water heater according to changes in external environmental factors such as seasonal changes, the overflow height of the outlet pipe can be easily changed by controlling the switching valve, so as to achieve the purpose of heating as much hot water as needed. Make the electric water heater in the best energy-saving state.

Abstract

The invention relates to an energy-saving variable-capacitance electric water heater, which comprises a container of inlet and outlet water tubes and an electric heating element. Wherein, said water outlet tube is formed by outer tube with overflow structure and a inner tube inserted in the outer tube; said inner tube can move between the first and second positions relative to the outer tube; when it is in the first position, the height of overflow water is higher than the one at the second position. The invention can adjust the water capacitance, control the heating water, and avoid energy waste.

Description

technical field [0001] The invention relates to an electric water heater, in particular to an improvement of a volumetric electric water heater, and belongs to the technical field of household appliances. Background technique [0002] Volumetric electric water heaters use a fixed-volume inner tank (commonly known as a water tank) to hold water and heat at a predetermined temperature. The structure is relatively simple and the operation and control are convenient, so it has been widely used. [0003] With the continuous deepening of the process of advocating the creation of a conservation-oriented society, consumers pay more attention to the power consumption performance of electric water heaters. Theory and practice have proved that the best energy-saving use of electric water heaters is to heat as much hot water as is needed. [0004] Due to changes in the external environment temperature and different water needs, not only the user's requirements for water temperature wil...
