A temperature controlling device includes a setting controller, a gas valve, a burner, an inlet temperature sensor, a water meter, and an operational controller. User sets a desired temperature via the setting controller. The inlet temperature sensor senses an inlet temperature of water at an inlet of a pipe, and then operational controller calculates a difference between the inlet temperature and the desired temperature to get a total heat for heating water in a predetermined heating time and transfer the total heat into a total gas consumption, and controls the gas valve to supply gas to the burner with an amount of the total gas consumption in a predetermined heating time. After that, water should be heated to the desired temperature, and the operational controller controls the gas valve to decrease the gas supply for maintaining water temperature.
F24H 1/10 - Continuous-flow heaters, i.e. heaters in which heat is generated only while the water is flowing, e.g. with direct contact of the water with the heating medium
G05D 23/19 - Control of temperature characterised by the use of electric means
F24H 9/20 - Arrangement or mounting of control or safety devices
A combustor of a water heater includes a burner member and a flame cover. The burner member has a passageway therein with an inlet and an outlet. The flame cover has a plurality of flame holes. The character of the present invention is that the burner member is provided with a room at a top thereof communicated with the passageway. A separating device is put in the room, and the flame cover is connected to the burner member to cover the separating device The separating device has a main outlet and two side outlets right under the flame holes of the flame cover to generate main flames and side flames respectively.
A combustor assembly of a water heater, which is provided between an air blower and a burner set to guide air from the air blower to the burner set, includes a first board, a second board and a third board stacked in sequence. Between the first board and the second board there is a first chamber and a first port, and between the second board and the first board there is a second chamber and a second port. The second board and the third board both have apertures. These boards restrict and divide an air flow of the air blower to flow along several paths to increase heat efficiency.
