Turbulent flow device, turbulent flow mixed type water storage tank and gas water heater of turbulent flow mixed type water storage tank

Abstract

The turbulent flow mixing type water storage tank comprises a tank body with a water inlet and a water outlet, and is characterized in that the turbulent flow device is arranged in the tank body, the turbulent flow device is composed of a turbulent flow shaft, a large impeller and a small impeller, the large impeller and the small impeller are installed on the turbulent flow shaft, one end of the turbulent flow shaft is installed at the water inlet end, and the other end of the turbulent flow shaft is installed at the water outlet end. Two or more small impellers are installed on the water inlet end, the other end of the water inlet end is installed at the other end, opposite to the water inlet end, in the tank body, a large impeller is installed on the water inlet end, and blades of the large impeller and blades of the small impellers are opposite in direction. The water mixing device has the advantages of automatic water mixing control, convenience in use, simple mounting structure and stable mixing of outlet water temperature.

Description

technical field [0001] The invention relates to the technical field of gas water heaters, in particular to the technical field of cold and hot mixed water tanks used for controlling the outlet water temperature of gas water heaters. Background technique [0002] Existing gas water heaters have the situation that the water temperature fluctuates when they are turned on for a second time. When they are turned off and turned on again within a short period of time, there will be a short-term high temperature phenomenon, which will cause burns and accidents. In order to alleviate this phenomenon, the most effective way is to The gas water heater is equipped with a water storage tank; and the gas water heater water storage tank on the market now needs to increase the volume of the water storage tank and design a more complex flow channel inside in order to ensure that the cold and hot water can be fully mixed during the flow process; When the volume of the water tank is small, the...

Problems solved by technology

[0002] Existing gas water heaters have the situation that the water temperature fluctuates when they are turned on for the second time. When they are turned off and turned on again for a short period of time, the temperature will be higher for a short time, and burns and accidents will occur. In order to alleviate this phenomenon, the most effective way is to The gas water heater is equipped with a water storage tank; and the gas water heater water storage tank on the market now needs to increase the volume of the water storage tank and design a more complicated flow channel inside in order to ensure that the hot and cold water are fully mixed during the flow process; When the volume of the water tank is small, the water flow path is short, the water cannot be mixed quickly, and the water temperature fluctuates greatly; its defects also include

[0003] 1. The internal structure of the existing water storage tank is complex and requires multiple weldings; the water channel structure is added inside the water tank, and the process is complicated, which affects production efficiency

[0004] 2. Due to the special structure of some special-shaped water storage tanks, the relatively complex internal flow channel structure has problems such as welding difficulties, poor welding consistency, and low durability test reliability in the production process.

[0005] 3. Limited by the space structure, material, processing and production costs, most of the water storage tanks are small in size, the water flow inside the tank is short, and the mixing effect of cold and hot water is relatively poor
