Single-floating ball water flowing device for heat-preservation water box of dual-liner solar water heater

Abstract

The invention relates to a single-floating ball water flowing device for a heat-preservation water box of a dual-liner solar water heater. A liner is divided into a large liner and a small liner by foaming polyurethane of a liner shell; a water flowing pipe passes through a polyurethane foaming layer between the large liner and the small liner so that water in the large liner is communicated with the water in the small liner by the water flowing pipe; and a water flowing floating ball is connected to the end of the water flowing pipe positioned in the small liner, so that the pipe orifice of the water flowing pipe positioned in the small liner is kept at an upper water level all the time and changes along with the change of water level in the small liner. The water flowing floating ball is connected to the end of the wall flowing pipe positioned in the small liner, so that the pipe orifice of the water flowing pipe positioned in the small liner is kept at the upper water level all the time and changes along with the change of the water level in the small liner; and therefore, the water in the large liner can flow into the upper layer of the water in the small liner as soon as possible, which ensures that hot water in the small liner is mixed uniformly and is supplied quickly and easily.

Description

【Technical field】 [0001] The invention belongs to the technical field of solar water heaters, and relates to a water-passing floating ball connected to the end of a water-passing pipe in a small inner tank, so that the nozzle of the water-passing pipe in the small inner tank is kept at the upper water level, and can It changes with the change of the water level in the small inner tank, so that the water in the large inner tank can flow into the upper water layer in the small inner tank as soon as possible, ensuring that the hot water in the small inner tank is mixed evenly, and the supply is fast and abundant. Single floating ball water passing device for heat preservation water tank of bile solar water heater. 【Background technique】 [0002] Existing solar water heaters generally adopt a single inner tank structure. Due to the large volume of the inner tank and large water storage, when electric auxiliary heating is used, first, the heating time is long and the water temper...

AI Technical Summary

Problems solved by technology

[0003] However, the above-mentioned double-inner solar heat preservation water tank has defects in the large and small inner tanks: when the small inner tank is heated by electricity in continuous rainy days, the water temperature of the small inner tank is increased to about 60 degrees, and the water temperature of the large inner tank is about 60 degrees. When the temperature is around 25 degrees, since the water temperature of the large inner tank is much lower than that of the small inner tank, the proportion of cold and hot water is different. The hot water outlet of the small inner tank flows out, causing a large amount of cold water to be released when the hot water is released, thus hindering the promotion and development of double inner tank solar water heaters
