A control method and device for a casing-type wall-hung boiler, and a casing-type wall-hung boiler

Abstract

The embodiment of the invention is applicable to the technical field of household appliances and provides a control method and device of a sleeve type wall-hung boiler and the sleeve type wall-hung boiler. The control method comprises the steps of calculating the domestic hot water load of the sleeve type wall-hung boiler according to the water outlet temperature, the water inlet temperature and the water flow of a domestic hot water pipe; calculating the first water flow of a heating hot water pipe according to the water outlet temperature, the water return temperature and the domestic hot water load of the heating hot water pipe and the first total load of the sleeve type wall-hung boiler; and adjusting the water flow in the heating hot water pipe to be matched with the first water flow.Through the control method provided by the embodiment of the invention, the problem that a traditional sleeve type wall-hung boiler cannot supply domestic hot water and heating hot water simultaneously is solved, the requirements of users using the domestic hot water and the heating hot water simultaneously are met, and user experience is improved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a control method and device for a casing-type wall-hung boiler and the casing-type wall-hung boiler. Background technique [0002] The casing-type wall-hung boiler is a water heater that can provide domestic hot water function and heating function, but when the casing-type wall-hung boiler is running, the above two functions cannot be performed at the same time. At present, most casing-type wall-hung boilers on the market give priority to the domestic hot water function. When the user uses domestic hot water, the heating function of the casing-type wall-hung boiler stops until the user finishes using the domestic hot water. The heating function will resume. If the user uses domestic hot water for a long time, the heating function will be interrupted for a long time, which greatly affects the heating effect of the casing wall-hung boiler.
