Problems solved by technology

However, although adding a neutralization water tank can alleviate the phenomenon of hot and cold water temperature during the first opening of the temperature process and when it is turned on again, the temperature of the pipes in the overall hot water system is still not uniform enough

Abstract

The invention discloses a self-circulating device. The self-circulating device is connected to a circulation loop of a water heater and comprises a water inlet pipe, a water outlet pipe, a circulating pipe, a first temperature sensor and a second temperature sensor, wherein the water inlet pipe is connected with a water return pipe of the circulation loop in series, the water outlet pipe is connected with a hot water outlet pipe of the circulation loop in series, a waterway switching device is arranged on the water inlet pipe, one end of the circulating pipe is connected with the waterway switching device, the other end of the circulating pipe is connected with the water outlet pipe, the first temperature sensor is arranged on the water inlet pipe, the second temperature sensor is arranged on the water outlet pipe, and the water inlet pipe is conducted with one of the water heater and the circulating pipe by the waterway switching device. According to the self-circulating device, whether water in the circulation loop needs to be heated can be selected, self circulation of hot water can be realized, and when the temperature meets the showering requirement, the water heater is not needed to heat, so that the uniformity of the hot water is guaranteed, and the hot and cold phenomena of water are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of fluid heaters, in particular to a self-circulating circulation device and a water heater with the circulation device. Background technique [0002] How to solve the hot and cold water temperature or overheating phenomenon when starting up for the first time or shutting down halfway and starting up again is a technical problem that needs to be solved in the field of water heaters. [0003] In the prior art, there are two main solutions to this problem: one is to add a circulation device. The hot water circulation device on the existing market is generally installed at the water inlet without a water temperature neutralization device, and the circulation device and the heating system of the host are two separate systems, which cannot control the co-operation of the host and cannot perform post-circulation, so The uniform temperature effect is not very ideal. [0004] The other is to add a water storage ta...
