Constant-temperature bin and water heater

Abstract

The invention discloses a constant-temperature bin and a water heater. The constant-temperature bin comprises a bin body, a first water temperature detection device, a cold water inlet pipe and a main control module, a hot water inlet pipe and a water outlet pipe are arranged on the bin body, and when the first water temperature detection device detects that high-temperature stored water enters a containing cavity of the bin body from the hot water inlet pipe, the main control module controls the operation of the cold water valve device to conduct the cold water inlet pipe, so that part of cold water is introduced into the containing cavity of the bin body to be mixed with the high-temperature stored water for cooling, and the mixed water flow can be further mixed with the hot water reserved in the containing cavity of the bin body. Therefore, cold water is introduced through the cold water inlet pipe to carry out water temperature compensation on the high-temperature stored water, the water temperature of the high-temperature stored water entering the bin body can be rapidly reduced, and the temperature difference between the water outlet temperature and the set temperature can be effectively reduced after the high-temperature stored water is mixed with the cold water and hot water reserved in the containing cavity and then discharged. Therefore, the water temperature fluctuation in the water cut-off and restarting process is reduced, and the comfort of a user for bathing with hot water is improved.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a constant temperature chamber and a water heater. Background technique [0002] For gas water heaters currently on the market, if the water valve is turned off and then turned on again in a short period of time, the hot water retained in the constant temperature chamber itself has a relatively high temperature, and the water stored in the water pipe will be heated due to heat exchange. The residual heat of the device continues to be heated, and its water temperature is much higher than the temperature of the hot water in the constant temperature tank. Therefore, the effect of using the hot water in the constant temperature tank to compensate for the temperature of the high-temperature storage water is relatively limited, and the final outlet water temperature is the same as the set temperature. There is still a large temperature difference, and the water temperature fluctu...

[0002] For gas water heaters currently on the market, if the water valve is turned off and then turned on again in a short period of time, the hot water retained in the constant temperature chamber itself has a relatively high temperature, and the water stored in the water pipe will be heated due to heat exchange. The residual heat of the device continues to be heated, and its water temperature is much higher than the temperature of the hot water in the constant temperature tank. Therefore, the effect of using the hot water in the constant temperature tank to compensate for the temperature of the high-temperature storage water is relatively limited, and the final outlet water temperature is the same as the set temperature. There is still a large temperature difference, and the water temperature fluctuates too much during the water stop and boiling process, which seriously affects the user's bathing comfort
