Instant heating type mixed water-saving and energy-saving water heater with storage function

Abstract

The invention relates to an instant heating type mixed water-saving and energy-saving water heater with the storage function, belongs to the technical field of household appliances and mainly solves the problem that water in the water pipe between a water heater and a water outlet switch can not be heated and is wasted. The water heater comprises a gas water heater, an electric water heater, a storage device, the water pipe and the water outlet switch; one water outlet switch, one electric water heater and one storage device are arranged at each use point; when the water outlet switch at a certain use point is opened, the gas water heater and the electric water heater related to the water outlet switch start to detect the temperature; if the temperature of the water is lower than the set temperature, the gas water heater and the electric water heater related to the water outlet switch start to heat; when the temperature of the water detected by a temperature sensing device of the auxiliary water heater reaches the set temperature, a control device instructs an electric heating device to stop heating; and as the electric water heater is used for reheating each use point, the yearned-for hot water can be obtained by opening the water outlet switch at any use point, so that the demands of hot water at a plurality of use points simultaneously can be satisfied.

Description

technical field [0001] The invention belongs to the technical field of household appliances, and in particular relates to an instant hybrid water-saving and energy-saving water heater with storage. technical background [0002] The most common household water heaters are gas-fired and electric. [0003] The advantages of gas-fired water heaters are: high power can provide hot water with large water flow, but the disadvantage is that the temperature rises slowly and produces a lot of exhaust gas. Based on safety considerations, the gas water heater will be considered to be placed in a semi-outdoor place. [0004] The advantage of the electric water heater is that it heats up quickly; the disadvantage is that it cannot provide hot water with a large flow immediately, and it is prone to personal safety accidents caused by electric shock. Based on its characteristics, storage electric water heaters are more commonly used. [0005] Regardless of whether it is a gas water heate...

Problems solved by technology

[0004] The advantage of the electric water heater is that it heats up quickly; the disadvantage is that it cannot provide hot water with a large flow immediately, and it is prone to personal safety accidents caused by electric shock.

[0005] Regardless of whether it is a gas water heater or an electric water heater, it is generally the case that a family installs one, but the point of use is often not the same. For example, points of use such as toilets, bathrooms, and kitchens all need hot water. For connection, because the points of use are scattered, and the water heater is in a fixed position, the length of the water pipes will be quite large, and these water pipes are already filled with water, and the water in these water pipes can only be obtained from the water outlet. The switch flows out, that is, the water in the water pipe between the water heater and the point of use cannot be reheated. If the water that has not been heated to the set temperature cannot be used, you can only watch the water flow away in vain. This water can only be wasted. The more dispersed the points of use, the longer the water pipes, the more water will flow away, and the greater the waste will be.

[0006] At the same time, because the heating water of the water heater needs to have a process of gradually increasing, the water flowing out during the heating stage is water that does not reach the set temperature, so the water can only be watched as it flows away, wasted in vain

[0007] In addition, after the water outlet switch is turned off, the water pipe between the water outlet switch and the water heater is already heated water, and the water will gradually cool down. can only be wasted

[0008] The applicant’s previous Chinese patents CN95205709.3, CN03126511.1, CN200710066626.2, and CN200820120213.8 disclosed water heater designs, which cannot solve the problem of water and energy waste in actual use
