Abstract
The utility model discloses a zero cold water return system, which comprises a cold water inlet pipe, a hot water inlet pipe and a return pump; cold water heats in the water heater, provides the water terminal from the hot water inlet tube, has the cooling water in the water pipe before using, opens the controller and lets the cooling water flow back to heating through the check valve through the return water pump, at this moment, when opening the use with the water terminal, just can use hot water to avoided giving up the cooling water, avoided causing the waste, practiced thrift the water resource, made things convenient for people's use moreover.
Description
Technical Field
The utility model relates to a heat energy-conserving system technical field specifically indicates a zero cold water return system.
Background
An existing hot water system generally comprises heating equipment, a water inlet pipeline, a water outlet pipeline and a water outlet end. The water inlet pipeline is generally a branch of a city tap water pipe network and is connected with heating equipment, then the water inlet pipeline is connected with the heating equipment, cold water of the tap water pipe network enters the heating equipment to be heated, and then the cold water is output to a water outlet end from the water outlet pipeline to be used by people. Therefore, a zero cold water return system becomes a problem to be solved urgently.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is a zero cold water return system.
In order to solve the technical problem, the utility model provides a technical scheme is a zero cold water return system: the water return system comprises a cold water inlet pipe, a hot water inlet pipe and a water return pump; the water supply system is characterized in that a cold water three-way pipe is arranged on the cold water inlet pipe and connected with a lower interface of the cold water three-way pipe, the hot water inlet pipe is connected with a water inlet of a water return pump, a hot water three-way pipe is arranged at a water outlet of the water return pump and connected with a lower interface of the hot water three-way pipe, a check valve is arranged between the cold water three-way pipe and an adjacent middle outlet of the hot water three-way pipe, and an upper outlet of the cold water three-way pipe and an upper outlet of the hot water three-way pipe are connected with a water terminal.
As an improvement, the conduction direction of the one-way valve is from a hot water three-way pipe to a cold water three-way pipe.
Compared with the prior art, the utility model the advantage lie in: cold water heats in the water heater, provides the water terminal from the hot water inlet tube, has the cooling water in the water pipe before using, opens the controller and lets the cooling water flow back to heating through the check valve through the return water pump, and at this moment, the water terminal just can use hot water when opening the use to avoided giving up the cooling water, avoided causing the waste, practiced thrift the water resource, made things convenient for people's use moreover.
Drawings
Fig. 1 is a schematic diagram of the connection principle of the zero-cold water return system of the present invention.
FIG. 2 is a schematic view of a water return pipeline system
As shown in the figure: 1. the system comprises a water return pipeline system, a cold water inlet pipe 2, a hot water inlet pipe 3, a water return pump 4, a cold water three-way pipe 5, a hot water three-way pipe 6, a hot water three-way pipe 7, a one-way valve 8 and a water using terminal.
Detailed Description
The following will explain the zero-cold-water return system of the present invention in detail with reference to the accompanying drawings.
With reference to fig. 1-2, a zero-cold-water return system includes a cold-water inlet pipe, a hot-water inlet pipe, and a return pump; the water supply system is characterized in that a cold water three-way pipe is arranged on the cold water inlet pipe and connected with a lower interface of the cold water three-way pipe, the hot water inlet pipe is connected with a water inlet of a water return pump, a hot water three-way pipe is arranged at a water outlet of the water return pump and connected with a lower interface of the hot water three-way pipe, a check valve is arranged between the cold water three-way pipe and an adjacent middle outlet of the hot water three-way pipe, and an upper outlet of the cold water three-way pipe and an upper outlet of the hot water three-way pipe are connected with a water terminal.
The conduction direction of the one-way valve is from a hot water three-way pipe to a cold water three-way pipe.
The utility model relates to a zero cold water return system's concrete implementation process as follows: cold water inlet tube and hot water inlet tube and being connected of water heater, cold water heats in the water heater, provides the water terminal from the hot water inlet tube, has the cooling water in the water pipe before using, and the controller on the water heater passes through the return water pump and lets the cooling water flow back to heating through the check valve, at this moment when opening the use once more with the water terminal, just can use hot water.
The present invention and its embodiments have been described above, but the description is not limited thereto, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should understand that they should not be limited to the embodiments described above, and that they can design the similar structure and embodiments without departing from the spirit of the invention.
