Problems solved by technology

[0006] The purpose of the present invention is to propose a hybrid energy constant temperature control water heater that organically combines gas heating and electric heating in view of the shortcomings or deficiencies of the above-mentioned prior art, so as to overcome the problems of complex temperature control and slow response in gas water heaters. At the same time as the shortcomings such as slowness, with the help of variable power electric heating to compensate for gas heating, the constant temperature control of the output water temperature can be effectively realized

Embodiment 1

[0022] This example Figure 4 As shown in the figure, 1 is the main water inlet, 2 is the air valve, 3 is the water flow sensor, 4 is the ventilation pipe, 5 is the combustion chamber, 6 is the igniter, 7 is the heat exchanger, 8 is the transformer, and 9 is the smoke collector Cover, 10 is the air inlet, 11 is the water inlet joint, 12 is the fan, 13 is the main water outlet, 14 is the water outlet joint, 15 is the temperature sensor, 16 is the water flow channel, 17 is the electric heating wire (or electric heating pipe) , 18 is a control circuit, and 19 is a gas hot water outlet. The mixed energy constant temperature control water heater is composed of a gas heating part and an electric heating part connected in series. The gas heating part is basically the same as the existing gas water heater. The main water inlet 1 connected to the cold water source exchanges heat with the gas heating part through the water flow sensor 3 The gas hot water outlet 19 from the heat exchang...

Embodiment 2

[0028] The mixed energy constant temperature control water heater of this embodiment is as Figure 5 As shown, the difference from the first embodiment is that the mixed energy thermostatically controlled water heater is composed of a gas heating part and an electric heating part connected in parallel. Among them, the main water inlet 1 connected to the cold water source communicates with the heat exchanger 7 of the gas heating part through the water flow sensor 3, and also communicates with the water inlet joint 11 of the electric heating part through the pipeline; and the gas heat from the heat exchanger The water outlet 19 and the water outlet joint 14 of the electric heating part are respectively connected to the water mixing valve 20 (also can be other water mixing devices), and the water outlet of the water mixing valve is used as the main water outlet 13 for supplying hot water, and a temperature sensor is installed 15.

[0029] For its working principle, refer to Embo...

Embodiment 3

[0031]The mixed energy constant temperature control water heater of this embodiment is as Image 6 As shown, the difference from Example 1 is that although the mixed energy constant temperature control water heater is composed of a gas heating part and an electric heating part in series, the main water inlet 1 connected to the cold water source first passes through the pipeline and the water inlet of the electric heating part The joint 11 communicates. The water outlet joint of the electric heating part communicates with the heat exchanger 7 of the gas heating part through the water flow sensor 3. A temperature sensor 15 is placed at the gas hot water outlet 19 from the heat exchanger. The hot water outlet serves as a supply The total water outlet 13 of hot water.

[0032] When working, although the electric heating part "compensates" in advance, and then the gas heating part heats the water temperature to the set temperature, but the power of the electric heating is still con...

The water heater has the advantages that the water heater is very sensitive and accurate in temperature regulation, and can effectively guarantee the temperature constancy of effluent water.

Description

technical field [0001] The invention relates to a constant temperature control water heater, in particular to a mixed energy constant temperature control water heater, which belongs to the technical field of water heaters. Background technique [0002] Constant temperature output of hot water is an important control performance of gas water heaters. The main factors affecting the hot water output temperature of traditional gas water heaters are gas volume, water flow rate, and air supply volume. When adjusting the output water temperature, for the sake of safety and environmental protection, it is necessary to take into account the matching of the gas volume and the air supply volume of the fan at the same time, so as to ensure that the gas is fully combusted. Therefore, the control of the output water temperature becomes a complex operation that requires comprehensive consideration of multiple factors. As a result, not only is the control sensitivity poor, but it is also e...
