Embodiment 1

[0029] see Figure 1 to Figure 3 , this embodiment provides a waterway connection structure 1, which is arranged on the heat exchange circulation pipeline 2 used to connect the water heater unit 3 and the water tank 4 at the water outlet of the hot water unit 3, wherein the waterway connection structure 1 includes an outer The tube 11, the inner tube 12, and the balloon tube 13 between the outer tube 11 and the inner tube 12. The air bag branch pipe 14 is connected, and the liquid between the outer pipe 11 and the air bag pipe 13 can flow to the inner pipe 12 through the air bag branch pipe 14 under the action of the pressure difference (referring to the pressure difference between the outer pipe 11 and the inner pipe 12), or the inner pipe 12 The liquid in the tube 12 can flow to the outer tube 11 through the airbag branch tube 14 under the action of pressure difference. In the design of the present invention, the waterway connection structure 1 is arranged outside the hot w...

Embodiment 2

[0035] This embodiment provides a modular hot water unit, including a hot water unit 3, a water tank 4, and the waterway connection structure 1 in Embodiment 1. The waterway unit 3, the waterway connection structure 1 and the water tank 4 are arranged side by side, and the waterway connection structure 1 is arranged on the heat exchange circulation pipeline 2 between the hot water unit 3 and the water tank 4.

[0036] see Figure 4 , the heat exchange circulation pipeline 2 is also provided with a water pump 6 and a first three-way valve 7, the water pump 6 is arranged at the water outlet of the hot water unit 3 and the waterway connection structure 1 is connected between the water pump 6 and the first three-way valve 7 During this period, the first outlet of the first three-way valve 7 communicates with the building user group 9 through the heat exchange circulation pipeline 2 , and the second outlet of the first three-way valve 7 communicates with the heat exchange pipeline ...

Abstract

The invention provides a waterway connection structure and a modular hot water unit, which relates to the technical field of heating equipment, and solves the problem in the prior art that the inside of the whole machine is very crowded and seriously disturbed because the expansion tank and other accessories are located inside the hot water unit. The technical problem of internal airflow field and poor heat transfer capacity. The waterway connection structure is arranged on the heat exchange circulation pipeline used to connect the water heater unit and the water tank at the water outlet of the waterway unit, wherein the waterway connection structure includes an outer pipe, an inner pipe and an airbag pipe between the outer pipe and the inner pipe , the two ends of the outer tube are connected to the two ends of the corresponding inner tube respectively, and the balloon tube and the inner tube are connected through the balloon branch tube. Under the action of the pressure difference, the liquid between the outer tube and the balloon tube can flow to the inner tube through the balloon branch tube , or the liquid in the inner tube can flow to the outer tube through the balloon branch. The invention is used to improve the heat exchange capacity of the hot water unit.

Description

technical field [0001] The invention relates to the technical field of heating equipment, in particular to a waterway connection structure and a modular hot water unit. Background technique [0002] At present, multifunctional water heaters generally have the functions of heating, hot water, and cooling. User-side equipment includes domestic hot water tanks, fan coils, and floor heating coils. The switching between heating, cooling and hot water is switched through the electric three-way valve. In the heating season, the function is switched from heating to hot water. To get hot water, at this time, the heating terminal equipment (fan coil, floor heating coil) on the user side stops the heat exchange cycle, and the electric three-way valve will switch to heating cycle. [0003] The multifunctional hot water machine with large cooling capacity is the first water machine product put on the market so far, and most of them were multifunctional hot water machines with small co...
