Solar linkage fuel gas rapid water heater with water mixing valve

Abstract

The invention discloses a solar linkage fuel gas rapid water heater with a water mixing valve. The solar linkage fuel gas rapid water heater comprises a heat exchanger, a combustor for providing heat for the water heater, a water feeding pipe, a water discharging pipe and a main controller, wherein the water feeding pipe and the water discharging pipe are connected to the heat exchanger; the water feeding pipe on the fuel gas rapid water heater is provided with the water mixing valve connected with the main controller, and two water inlets of the water mixing valve comprise a cold water inlet and a discharged water connection opening of the solar water heater correspondingly. The solar linkage fuel gas rapid water heater is characterized in that the cold water inlet and the discharged water connection opening of the solar water heater are provided with a first temperature sensor and a second temperature sensor correspondingly, wherein the first temperature sensor and the second temperature sensor are connected with the main controller, and the main controller changes the water inflow of the cold water inlet and the discharged water connection opening of the solar water heater according to signals fed back by the first temperature sensor and the second temperature sensor. When the solar linkage fuel gas rapid water heater works, the temperature of the discharged water of fuel gas rapid water heater can always be maintained at the user set temperature stably, the constant temperature effect is outstanding, and hot water of the solar energy water heater is utilized to the maximum degree while user requirements are met.

Description

technical field [0001] The invention relates to the technical field of gas instant water heaters, in particular to a solar energy linkage gas instant water heater with a water mixing valve. Background technique [0002] When solar water heaters in the prior art are in use, due to changes in the morning and evening and seasons, solar water heaters cannot guarantee to provide sufficient hot water within 24 hours a day, or cannot satisfy multiple continuous or simultaneous use, especially in At night or in winter, the hot water temperature of the water heater cannot meet the user's requirements. For example, it takes at least two hours for a solar water heater to heat a box of water at 20 degrees Celsius to the bottom of 60 degrees Celsius in winter. In order to solve the problem that the water temperature in the water heater water tank is not enough when the sunlight is not sufficient, the existing household appliance type solar water heater is usually used in conjunction wit...

Problems solved by technology

[0004] However, in this scheme: due to the limitation of the minimum temperature rise K (gas water heaters generally exist at 4-5°C), when the water inlet temperature is at the ignition temperature T ref1 and flameout temperature T ref2 During the interval, the gas water heater does not start, and the outlet temperature of the gas water heater is at T ref1 -T ref2 Between, can not be stable at the set temperature, can not meet the constant temperature requirements
