However, due to the influence of various factors, the flow rate and water pressure of the hot water and cold water pipelines are unstable, which can easily lead to the inability to strictly control the mixing ratio of hot water and cold water, resulting in hot and cold water.
Secondly, when the user’s family has several water points, when the second water point is opened at the same time, the current mixed water cooling method will affect the balance of cold and hot water at the first point, causing the first water point to be cold and suddenly cold. hot

The invention discloses a cooling type constant temperature water heater, which comprises a water tank, a water outlet system, a first temperature sensor and a controller. The water outlet system includes a water collector, a plurality of sequentially arranged three-way valves and a plurality of sequentially arranged heat dissipation channels . The three-way valve includes a three-way water inlet, a normally open water outlet and a normally closed water outlet. When closed, the three-way water inlet communicates with the normally open water outlet; Multiple normally open water outlets communicate with the water collector, and the three-way water inlet of the first three-way valve communicates with the water tank. The last cooling channel is connected to the normally closed water outlet of the last three-way valve and the water collector, and each of the remaining cooling channels is connected to the normally closed water outlet of the previous three-way valve and the three-way water inlet of the latter three-way valve. The first temperature sensor is used to sense water temperature. The controller controls the opening and closing of the three-way valve according to the difference between the water temperature and the temperature set by the user. The larger the difference is, the more the three-way valves are opened in turn. In this way, a constant temperature outlet water can be provided.
Description
technical field [0001] The invention relates to the field of water heaters, in particular to a cooling type constant temperature water heater. Background technique [0002] At present, water heaters such as gas water heaters, electric water heaters, solar water heaters, and heat pump water heaters control the temperature of the outlet water by mixing hot water and cold water. However, due to the influence of various factors, the flow rate and water pressure of the hot water and cold water pipelines are unstable, which can easily lead to the inability to strictly control the mixing ratio of hot water and cold water, resulting in intermittent hot and cold water. Secondly, when the user’s family has several water points, when the second water point is opened at the same time, the current mixed water cooling method will affect the balance of cold and hot water at the first point, causing the first water point to be cold and suddenly cold. hot. When the first water point is adj...
