Description

Mixing arrangement and hanging stove

Technical Field

The utility model relates to the field of electric appliances, in particular to a mixing device and a wall-mounted furnace.

Background

When the wall-mounted boiler uses the bathroom hot water function, cold water (tap water) enters the wall-mounted boiler to exchange heat with the plate heat exchanger in the wall-mounted boiler to reach the target temperature, and then flows out of the wall-mounted boiler to enter a water terminal (a tap or a bathroom shower). However, when the wall-mounted boiler is not in use, the wall-mounted boiler needs to be closed and opened when the wall-mounted boiler is in need, at this time, the restarting process from the start of ignition until the ignition is successful to enter a normal combustion state takes about 4-6 seconds, cold water (tap water) in the restarting process passes through the plate heat exchanger and directly enters the water terminal (faucet or bathroom shower) without being heated, and partial hot water is reserved in the pipeline of the water terminal before, so that the phenomenon of sudden cold and hot bathroom temperature of 'heat, cold and hot' occurs, and the bathroom comfort of water is seriously affected.

In order to solve the uncomfortable problem that the wall-mounted furnace is suddenly cold and suddenly hot in the bathroom use process, the traditional wall-mounted furnace is improved by adding a mixing device in the current market, so that the temperature difference between the cold and the hot is reduced as much as possible, and the comfort is improved; specifically, as in the prior document with the application number of CN201521085968.5, a mixing water tank is additionally arranged between the wall-mounted furnace and the water-using terminal, hot water in the mixing water tank is utilized to be mixed with cold water flowing out of the wall-mounted furnace in the restarting process, so that the temperature of the cold water is increased, and the temperature difference of water entering the water-using terminal is reduced; however, when the cold water enters the equivalent volume of the mixing water tank, the hot water with the same equivalent volume in the mixing water tank is extruded from the inside of the water tank and directly enters the bathroom water outlet pipeline to flow into the water terminal, and the hot water with the equivalent volume is directly wasted without being mixed with the cold water, so that the mixing proportion of the hot water and the cold water is reduced, and the mixing effect is reduced.
