Embodiment 1

[0031] like figure 1 , figure 2 As shown, a domestic hot water constant temperature wall-hung boiler includes: a main heat exchanger 1 and a plate heat exchanger 2, a heating circuit is connected to the main heat exchanger 1, and a circulation pump is installed on the heating circuit 3 and the expansion tank 4, the domestic hot water pipeline is connected to the plate heat exchanger 2, and the plate heat exchanger 2 and the main heat exchanger 1 are connected through pipelines to form a small loop; its features That is, the plate heat exchanger 2 is connected with a water mixing chamber 5, and the domestic hot water flowing out from the plate heat exchanger 2 enters the domestic hot water pipe after passing through the water mixing chamber 5. road.

[0032] Wherein, a fume collecting hood 6 and a burner 13 are provided corresponding to the main heat exchanger 1 , a fan 7 is installed on the fume collecting hood 6 , and a gas proportional valve 14 is connected to the burner ...

Embodiment 2

[0038] This embodiment provides a domestic hot water constant temperature wall-hung boiler, its structure is basically the same as that of Embodiment 1, the difference lies in:

[0039] 1. A domestic hot water inlet 8 is provided on the plate heat exchanger 2, and a domestic hot water outlet 9 is provided on the mixing chamber 5, such as Figure 4 shown. In order to ensure the water mixing effect, it is preferable that the domestic hot water outlet 9 , the connection port 12 between the plate heat exchanger 2 and the water mixing chamber 5 are respectively located at both ends of the water mixing chamber 5 .

[0040] 2. The size of the water mixing chamber 5 is larger than that of the plate heat exchanger 2 , and the plate heat exchanger 2 is installed in the middle of the water mixing chamber 5 . In other implementation manners, the plate heat exchanger is installed at one end of the water mixing chamber, which is not limited to this embodiment.

[0041] 3. A preheating cir...

Abstract

The invention discloses a domestic hot water constant-temperature wall-hanging stove. The domestic hot water constant-temperature wall-hanging stove comprises a main heat exchanger and a plate type heat exchanger. The main heat exchanger is connected with a heat supply loop, and the heat supply loop is provided with a circulation pump and an expansion water tank. The plate type heat exchanger is connected with a domestic hot water supply pipeline. The plate type heat exchanger and the main heat exchanger are connected through a pipeline to form a small loop. The domestic hot water constant-temperature wall-hanging stove is characterized in that the plate type heat exchanger is connected with a water mixing cavity, and domestic hot water flowing out of the plate type heat exchanger enters the domestic hot water supply pipeline after passing through the water mixing cavity. The water mixing cavity is additionally formed in the plate type heat exchanger, and the water storage function canbe achieved while the basic heat exchange function of an original plate type heat exchanger is reserved. After water supply is started and stopped in the hot water usage process, cold water and hot water are mutually neutralized, domestic hot water temperature fluctuation is relieved, the constant domestic hot water temperature of the wall-hanging stove is achieved, and accordingly, the comfort of the domestic water is improved.

Description

technical field [0001] The invention relates to the technical field of fluid heaters, in particular to a domestic hot water constant temperature wall-hung boiler. Background technique [0002] Gas wall-hung boiler, referred to as "wall-hung boiler", is a kind of thermal equipment that uses natural gas or liquefied gas as fuel, heats circulating water after burning and releasing heat in the main heat exchanger, so as to provide heating medium or domestic hot water for buildings. According to the difference of heat exchanger structure, it is mainly divided into two categories: one is the main heat exchanger plus plate heat exchanger structure, and the other is a single heat exchanger with casing structure. In the existing dual-purpose wall-hung boilers with plate heat exchangers, in the process of using domestic hot water, the phenomenon of hot and cold water temperature exists after turning off the water and turning on the water again. Contents of the invention [0003] Ai...
