Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with examples and accompanying drawings, but the embodiments of the present invention are by no means limited thereto.

[0013] Concrete structure of the present invention sees figure 1 with image 3 , see the specific implementation figure 2 . The water inlet (4) of the waste heat recovery device for shower waste water is connected with the running water pipe (5), and the water outlet (6) is connected with one end of the flexible pipe (7). The other end of flexible pipe (7) is connected with heater water inlet (8), and the person stands on this shower waste water recovery device, and the waste water heat exchange metal coil pipe (1) after shower. According to the principle of heat conduction, the residual temperature of waste water exchanges heat with the cold water in the metal coil tube (1) cavity of the heat exchanger, and the water source enters the heat exchange metal coil tube (1) ...

Abstract

The invention relates to an excess heat recovery device for shower waste water, comprising a waste water collecting plastic tray and a circular heat change metal coil pipe fixed in the waste water collecting plastic tray. When a user takes a shower standing on the excess heat recovery device for waste water, flowing waste water has a certain residual temperature. After collected by the waste water tray, the residual temperature and cold water in the cavity of the heat change metal pipe exchange heat. The cold water rises to a certain temperature to heat a heater which can rapidly reach a required temperature so that the energy source is saved. The invention has simple structure, high recovery rate, practicality and convenience, and can be matched with various heaters heated by electricity, coal gas, solar energy, and the like.

Description

technical field [0001] 1. The function of the present invention is to recycle the waste heat in the waste water, recycle the waste heat in the shower, and save energy. [0002] 2. The structure of the present invention is simple and practical, and only consists of a waste water collection tray (2) and a heat exchange metal coil (1). 3 background technology [0003] The waste hot water after the shower is generally directly discharged into the sewer, and there is still a certain residual temperature (about 35°C) in the waste water, which is directly discharged to cause waste. In the invention, waste water with residual temperature is first collected in the tray, and then absorbed by the cold water in the coil pipe in the tray. If the heater needs a lot of power to heat cold water, and warm water enters the heater, it can be heated to the same temperature with only a small power, so that the waste heat is reused and energy is saved. Contents of the invention [0004] The o...
