Automatic-heat-exchange energy-saving bathtub device

Abstract

The invention provides an automatic-heat-exchange energy-saving bathtub device. The automatic-heat-exchange energy-saving bathtub device comprises a bathtub module, a heat exchange module and a pipeline module; the bathtub module comprises a bathtub; a bathing pool is arranged in the bathtub, and a water plug is arranged at a drainage hole; a bath tub is arranged inside the bathing pool; a positioning groove is formed in the lower end of the bathing pool; the heat exchange module comprises a heat exchange cavity; the pipeline module comprises a cold water pipe; a drain valve is arranged at thetop of the cold water pipe. According to the automatic-heat-exchange energy-saving bathtub device, through the heat exchange module, after usage, cold water in the cold water pipe is subjected to heat exchange operation whole hot water is discharged, heat energy in the hot water can be recycled, in this way, much energy is saved, and the cost for bathing of the bathtub is saved.

Description

technical field [0001] The invention relates to the field of energy saving and environmental protection, in particular to an automatic heat exchange bathtub device. Background technique [0002] A bathtub is a water pipe device for bathing or showering, and is usually installed in a home bathroom. When using a bathtub, the user first needs to inject bathing water into the bathtub through a water valve. After injecting an appropriate amount of bathing water at a suitable temperature, The user can enter the bathtub for bathing; after the user takes a bath, if it needs to be used again, the user needs to open the drain valve at the bottom of the bathtub to discharge the used bathing water, and then re-inject the bathing water; After the user finishes using the bathing water in the bathtub, the heat in the water will be eliminated without all consumption, so a large amount of heat in the water will be wasted; and the existing bathtub device does not have the ability to store hea...

[0002] A bathtub is a water pipe device for bathing or showering, and is usually installed in a home bathroom. When using a bathtub, the user first needs to inject bathing water into the bathtub through a water valve. After injecting an appropriate amount of bathing water at a suitable temperature, The user can enter the bathtub for bathing; after the user takes a bath, if it needs to be used again, the user needs to open the drain valve at the bottom of the bathtub to discharge the used bathing water, and then re-inject the bathing water; After the user finishes using the bathing water in the bathtub, the heat in the water will be eliminated without all consumption, so a large amount of heat in the water will be wasted; and the existing bathtub device does not have the ability to store heat in the bathing water. Therefore, it is not conducive to the saving of hot water energy; in addition, the current domestic hot water supply device is mainly supplied by a water heater, so every time when changing the bathing water in the bathtub, the user needs to re-inject hot water, so that The operation of hot water will greatly increase the usage of hot water, which is not conducive to the saving of hot water energy; in summary, there are defects
