Abstract

The invention belongs to the technical field of water heaters, and particularly relates to a cyclic heating energy-saving water heating device capable of keeping constant temperature. The device comprises a storage tank, an inner circulating inlet, an inner circulating outlet, an outer circulating inlet, an outer circulating outlet and a water filling nozzle are formed in the storage tank, a circulating pump is further arranged in the storage tank, the circulating pump is connected through a hose, a mixing unit is fixedly mounted on the circulating pump, and the circulating pump is in transmission connection with the mixing unit; the invention further provides a using method of the device, the using method comprises the steps of water heater heating, flow dividing, water temperature direct neutralization and the like, and compared with the prior art that hot water is directly gathered into a storage tank, the device has the advantages that the time for circularly heating cold water in the storage tank to hot water is shortened by 20% or above, meanwhile, cold water and hot water are evenly mixed, and the condition of different local temperatures is avoided; and the situation that the water heater is excessively heated due to the fact that the temperature of the inner circulating outlet is lower than the temperature of the inner circulating inlet is avoided, and accurate heating of the water temperature is guaranteed.

Description

technical field

[0001] The invention belongs to the technical field of water heaters, and in particular relates to a constant temperature circulation heating energy-saving hot water device and a use method thereof. Background technique

[0002] The domestic hot water circulation system is an environmentally friendly system for domestic water preheating and circulation. The system can be used with various water heaters such as gas water heaters, volumetric, instantaneous, solar energy, and air energy, and can be installed with or without return pipes.

[0003] If the domestic hot water pipeline is longer (the water heater is longer from the hot water tap), each time you use hot water, you need to wait for a long time, and cold water will be released for a long time, which is wasted in vain. This family may consider installing a hot water circulation system. For high-end hotels with unified water supply and 24-hour business premises, in order to allow customers to use hot wa...

Examples

Embodiment 1

[0067] like Figure 1-7 As shown, a circulating heating and energy-saving hot water device that maintains a constant temperature includes a storage tank 1. The storage tank 1 is provided with an inner circulation inlet 11, an inner circulation outlet 12, an outer circulation inlet 13, an outer circulation outlet 14 and a water injection port 15. There is also a circulation pump 2 inside the storage tank 1, the circulation pump 2 is connected through a hose 111, and a mixing unit 3 is fixedly installed on the circulation pump 2, and the circulation pump 2 is connected to the mixing unit 3 by transmission;

[0068] A reciprocating unit 4 is also installed on the circulation pump 2 , and the reciprocating unit 4 is fixed on the inner wall of the storage tank 1 .

[0069] The device is also equipped with an external circulation pipe and an internal circulation pipe. The two ends of the external circulation pipe are respectively connected to the external circulation inlet 13 and th...

Embodiment 2

[0089] This embodiment is a further improvement of the previous embodiment, such as Figure 1-7 As shown, a circulating heating and energy-saving hot water device that maintains a constant temperature includes a storage tank 1. The storage tank 1 is provided with an inner circulation inlet 11, an inner circulation outlet 12, an outer circulation inlet 13, an outer circulation outlet 14 and a water injection port 15. There is also a circulation pump 2 inside the storage tank 1, the circulation pump 2 is connected through a hose 111, and a mixing unit 3 is fixedly installed on the circulation pump 2, and the circulation pump 2 is connected to the mixing unit 3 by transmission;

[0090] A reciprocating unit 4 is also installed on the circulation pump 2 , and the reciprocating unit 4 is fixed on the inner wall of the storage box 1 .

[0091] The device is also equipped with an external circulation pipe and an internal circulation pipe. The two ends of the external circulation pipe...
