Problems solved by technology

That is, due to the circulation of cold water and hot water in the entire water heater system, one problem that cannot be avoided is that the water heater may leak
[0005] Thus, if the water heater leaks, a large amount of water will be wasted, and if the leaked water is already heated hot water, a large amount of thermal energy or electric energy will be wasted

[0022] figure 1 A block diagram of a water heater according to a first embodiment of the present invention is schematically shown.

[0023] Such as figure 1 As shown, the water heater according to the first embodiment of the present invention includes: a water heater tank 1, a heater 2, a water inlet pipe 3 connected to the water heater tank 1, and a water outlet pipe connected to the water heater tank 1 4. The water level detector 11 arranged in the water heater tank 1 , the water outlet switch 5 connected to the water outlet end of the water outlet pipe 4 , the control unit 10 and the warning unit 20 .

[0024] Wherein, the control unit 10 is connected to the heater 2 so as to control the start, stop, heating temperature and the like of the heater 2 .

[0025] Wherein, the water level detector 11 is used to detect the change of the water level of the water heater tank 1 after starting.

[0026] Wherein, when the water outlet switch 5 is turned off, it sends a first signal...

[0035] figure 2 A flow chart of a water heater leakage detection method according to the second embodiment of the present invention is schematically shown.

[0036] Such as figure 2 As shown, the water heater leakage detection method according to the second embodiment of the present invention includes:

[0037] The first step S10: closing the water outlet switch 5,

[0038] Second step S20: sending a first signal S1 indicating that the water outlet switch is closed to the control unit 10;

[0039] The third step S30: sending a second signal S2 for activating the water level detector 11 to the water level detector 11 so that the water level detector 11 starts to work to detect the water level change of the water heater tank 1;

[0040] The fourth step S40: judging whether the water level of the water heater tank 1 has changed;

[0041] If it is judged that the water level of the water heater tank 1 has changed, the fifth step S50 is executed to make the warning unit issue...

Abstract

The invention discloses a water heater, wherein a water outlet switch is used for transmitting a first signal to a control unit when the switch is turned off; the control unit, while receiving the first signal from the water outlet switch, is used for transmitting a second signal to a water level detector; the water level detector, when the second signal is received from the control unit, starts to work to detect water level variation of a water heater water storage barrel, and is used for transmitting a third signal showing the water level variation of the water heater water storage barrel to the control unit under a circumstance that the water level variation of the water heater water storage barrel is detected; the control unit is used for transmitting a fourth signal for starting a prompting unit when the third signal is received from the water level detector; and the prompting unit, while receiving the fourth signal, is used for transmitting caution information; furthermore, the control unit is used for transmitting a fifth signal for commanding the heater to stop heating temporarily when the third signal is received from the water level detector.

Description

technical field [0001] The invention relates to the field of household appliances, and more specifically, the invention relates to a water heater. Background technique [0002] A water heater refers to a household electrical device that raises the temperature of cold water into hot water within a certain period of time through various physical principles. According to different principles, water heaters can be divided into electric water heaters, gas water heaters, solar water heaters, speed magnetic domestic water heaters, etc. [0003] The water heater heats the water in the water heater tank through a heating unit that utilizes energy such as electric energy, gas, solar energy, or electromagnetic energy to heat water. Thereafter, when hot water is needed, the hot water heated by the heating unit can be used by adjusting the hot water switch. [0004] But, when water heater is used actually, there is such a problem. That is, since there is a circulation of cold water an...
