Problems solved by technology

After the bath water is used, it is directly drained through the drain pipe through the floor drain. The temperature of the bath waste water is generally around 35°C. The drained waste water contains a lot of heat, which is a serious waste of energy.
In order to solve the above problems, in the patent "A Floor Drain with Waste Hot Water Recovery Interface" (authorized publication number CN 1948645A), a floor drain with a waste hot water extraction path is described, but this technology has the following problems: 1. The floor drain cannot directly recover the heat of waste hot water, and needs to recover heat energy through a separate external waste heat recovery device; 2. The waste water itself cannot meet the pressure loss required to flow from the floor drain extraction channel to the waste heat recovery device, and needs to pass through sewage The pump is pressurized, which increases the investment and the consumption of high-quality electric energy; 3. Since the waste hot water is sewage, the waste hot water flows in the extraction channel for a long time, and it is easy to scale on the inner wall of the pipeline, and it is relatively difficult to remove the scale; 4. There is no deodorization and Anti-insect function

Abstract

The invention discloses a floor drain for recycling heat of bathing waste water, which belongs to the field of energy-saving products. The floor drain for recycling heat of bathing waste water consists of a floor drain main body, a floor drain core, a filter screen, a deodorization and insect prevention device and a waste water heat recycling device, wherein a crimped rim edge at the upper end of the floor drain core is sleeved on a circular step of the floor drain main body; the deodorization and insect prevention device is arranged at the lower end of the floor drain core; a floor drain cover plate of the waste water heat recycling device is arranged in a rectangular step of the floor drain main body; a heat exchange tube is arranged in the floor drain core; the filter screen is arranged on the circular step of the floor drain core; during bathing, tap water exchanges heat with waste water through the floor drain cover plate and the heat exchange tube to recycle heat of bathing waste water; and when the waste water reaches a certain liquid level in the floor drain core, the deodorization and insect prevention device is opened under the action of gravity force to drain the waste water through a sewer. The floor drain has the advantages of simple structure, capabilities of fully recycling heat of bathing waste water, saving energy sources and preventing sewer odor from polluting indoor air, good economic and social benefits and suitability for household bathrooms.

Description

technical field [0001] The invention belongs to the field of energy-saving products, in particular to a floor drain for recovering the heat energy of bathing wastewater. Background technique [0002] With the improvement of people's living standards and the gradual development of good living habits, the consumption of hot water for bathing in families continues to increase. After the bathing water is used, it is directly drained through the drain pipe through the floor drain. The temperature of the bathing wastewater is generally around 35°C. The drained wastewater contains a lot of heat, which is a serious waste of energy. In order to solve the above problems, in the patent "A Floor Drain with Waste Hot Water Recovery Interface" (authorized publication number CN 1948645A), a floor drain with a waste hot water extraction path is described, but this technology has the following problems: 1. The floor drain cannot directly recover the heat of waste hot water, and needs to rec...
