Instant-heating mixed type water-saving energy-saving water heater

Abstract

The invention discloses an instant-heating mixed type water-saving energy-saving water heater, which belongs to the technical field of household appliances and mainly solves the problem that the water in a water pipe between a water heater and a water outlet switch is wasted as the water cannot be reheated. The instant-heating mixed type water-saving energy-saving water heater comprises a gas water heater, electric water heaters, the water pipe and the water outlet switches. Each using point is provided with one water outlet switch and one electric water heater, the temperature can be started to be detected by the gas water heater and the electric water heater related to the water outlet switch when the water outlet switch in one using point is switched on; if the water temperature is lower than a set temperature, the gas water heater and the electric water heater related to the water outlet switch start to heat, and an electric heating device is commanded to stop heating by a control device when the water temperature information detected by a temperature sensor of the electric water heater is reached to side set temperature information; and since each using point is provided with the electric water heater for heating, desired hot water can be obtained very soon by opening the water outlet switch in any using point, and the requirement on hot water in multiple using points can be simultaneously met.

Description

technical field [0001] The invention belongs to the technical field of household appliances, in particular to an instant hybrid water-saving and energy-saving water heater. 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 heater or an electric water he...

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
