Heating equipment controlling fuel-heated water with changeable heating rate

Abstract

The invention discloses heating equipment controlling fuel-heated water with changeable heating rate. The heating equipment controlling fuel-heated water with changeable heating rate comprises a baseand a heating cylinder. The heating cylinder is arranged at the upper end of the base. The base is connected with the heating cylinder through welding. A pilot burner is arranged at the right end of the outer side of the lower end of the heating cylinder. A fixing end is arranged at the upper end of the heating cylinder. According to the heating equipment controlling fuel-heated water with changeable heating rate, an existing electric protection wall assembly structure is changed by the structure; an inner casing pipe and an outer casing pipe are installed on a cold water input pipe and a coldwater output pipe respectively in a split manner; assembling is simple; in particular, replacement of the inner casing pipe and the outer casing pipe is quite convenient; for an electric protection wall assembly with the inner casing pipe damaged caused by situations such as dry burning, the inner casing pipe can be replaced separately; for electric water heaters with requirements for installation directions of the water input pipe and the water output pipe, installation and use of an electric protection wall can be achieved; safety of the water heater is enhanced; matching with an arc face of a shell middle barrel is closer; and the heating equipment plays a better anti-overflowing role.

Description

technical field [0001] The invention belongs to the related technical field of water heaters, and in particular relates to a water heating device for controlling fuel heating with a variable heating rate. Background technique [0002] Most of the water heaters are water storage electric water heaters. Water storage electric water heaters are divided according to the structural form, which can be divided into closed type and open outlet type. Since the outlet open type water heater has a single purpose, consumers use more closed type water heaters. Electric water heaters, as we all know, heat pumps are combined with domestic water heaters, where hot gas is used to exchange heat with the water circulated by the water heater to provide an additional source of heat to heat the water, which often results in complex equipment integrated into the unit. [0003] The existing heating equipment technology has the following problems: most of the existing water heaters are equipped with...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of fuel heating water heating equipment with variable heating rate control, to solve the problem that most of the existing water heaters proposed in the above background technology are equipped with water storage tanks and water inlet and outlet pipes. If the water inlet and outlet pipes are directly Inserted into the water inlet and outlet of the water tank, there is a certain gap due to the uneven hole wall, uneven stress, deformation, damage, etc. It will cause the foaming material to leak out. At the same time, after the water heater is used for a long time, it may cause electric leakage, which may endanger human health in serious cases.
