Abstract

The invention discloses a waste water waste heat recovery device and a shower device comprising the same, belongs to the technical field of heat exchangers, and aims to achieve the energy saving effect. The waste water waste heat recovery device comprises a waste heat waste water collecting container (2), and an outlet of the container communicates with a hot water inlet (411) of a heat exchanger.The waste water waste heat recovery device is characterized in that the heat exchanger is a sleeve backflow heat exchanger, a sleeve is in a disc shape formed through layer-by-layer winding, and thewinding sleeve backflow heat exchanger is formed. An inner pipe of the sleeve is a hot water pipe of the heat exchanger. The high temperature end of the winding sleeve backflow heat exchanger is in the center of the winding sleeve backflow heat exchanger. The sleeve is a hose. The pipe wall of the inner pipe of the sleeve is thinner than that of an outer pipe of the sleeve. A hot water outlet of the heat exchanger is higher than the disc-shaped sleeve (4) of the winding sleeve backflow heat exchanger. The shower device comprises a water feeding device, a water discharging device and a water heater and is characterized in that the shower device further comprises the a waste water waste heat recovery device, discharged water enters the waste heat waste water collecting container, and fed water passes through a cold water pipeline of the winding sleeve backflow heat exchanger and then enters the water heater.

Description

technical field [0001] This patent application belongs to the technical field of heat exchangers, relates to waste heat recovery devices for waste water, and can be applied to shower devices. Background technique [0002] The waste water in the shower process contains a lot of heat, and the prior art has not made good use of it, so that the instant electric shower device must be equipped with a power load beyond what ordinary household circuits can bear. The water heater mentioned in this patent application can refer to (but not limited to) the water heater introduced in the Chinese patent with application number 2015200483172, especially the electric water heater of this type. Contents of the invention [0003] The purpose of this patent application is to provide a wastewater waste heat recovery device and a shower device including it. It has energy saving effect. [0004] This purpose is achieved in this way: the waste heat recovery device adopts a casing countercurren...
