Abstract

The invention discloses a water heater and a control method thereof. The water heater comprises a water level switch group and a controller, wherein the water level switch is arranged inside a water tank of the water heater and comprises at least four water level switches at different heights; when the water heater is in operation, two water level switches of the at least four water level switches are in an on state, and the rest water level switches are in an off state; the controller is connected with the water level switch group and is used for judging whether the two water level switches in the on state have faults; and when any one water level switch in the on state has faults, the two water level switches in the on state are controlled by the controller to be off, and any two water level switches in the off state are controlled by the controller to be on. The water heater can be free from halt caused by the faults of the water level switches.

Description

technical field [0001] The invention relates to the field of water heaters, in particular to a water heater and a control method thereof. Background technique [0002] At present, because the water level switch of the air source heat pump water heater is immersed in hot water for a long time, it is prone to failure. Once the water level switch fails, the water heater will stop and cannot continue to operate. [0003] Aiming at the problem in the related art that the hot water machine is prone to shut down due to the failure of the water level switch, no effective solution has been proposed yet. Contents of the invention [0004] The main purpose of the present invention is to provide a water heater and its control method, so as to solve the problem in the related art that the water heater is prone to shutdown due to a failure of the water level switch. [0005] In order to achieve the above object, according to one aspect of the present invention, a water heater is provid...
