Shower waste water residual heat circulated usage device

Abstract

The invention discloses a circulating utilizing device of residual heat of waste bath water, which comprises the following parts: evaporator, compressor, condenser, bulking valve, heating tank and water collecting tank to collect waste bath water, wherein the heating tank connects the tank to store bath water; the evaporator is set in the water collecting tank; the condenser is set in the heating tank. The invention recycles to utilize the heat of waste bath water, which shortens the heating time for bath water.

Description

technical field [0001] The invention relates to a sanitary bathing device, in particular to a bathing waste water waste heat recycling device which can recycle the waste heat contained in the bathing waste water. Background technique [0002] With the improvement of living standards, more and more bathing utensils are used in people's daily life, and people's demand for sanitary hot water is also increasing. Now, the main way to provide hot water for bathing utensils is electric heating. Water heaters, connected to the municipal hot water network for centralized hot water supply, gas-fired water heaters, solar water heaters, etc. Among them, although the central hot water supply connected to the municipal hot water network can be used immediately, it is troublesome to install, the cost of the user is high, and it is inconvenient to use; Solar water heaters are more convenient to use and can be installed and designed according to people's own needs. However, if these water h...

Problems solved by technology

Among them, although the central hot water supply connected to the municipal hot water network can be used immediately, it is troublesome to install, the cost of the user is high, and it is inconvenient to use; Solar water heaters are more convenient to use and can be installed and designed according to people's own needs. However, if these water heaters are used for too long and use too much water, the water heating will not be timely and the temperature of people's bathing water will drop. phenomenon, which has brought great inconvenience to people's bathing

And when people take a bath, the bath waste water after bath contains a large amount of heat, as the water temperature before being heated is 5~15 ℃ when entering the water in the water heater, and the bath water temperature after heating is 45~50 ℃ At this time, the temperature of the bathing wastewater after bathing can reach 35-45°C, that is, the heat consumed by the wastewater after bathing is as high as 70% of the heat generated by the water heater. The discharge of waste water is wasted in vain, which not only increases the workload of the water heater, but also increases the energy consumption of the water heater.
