Integrated heat recovery floor unit

Abstract

The invention discloses an integrated heat recovery floor device, which includes a floor drain, a drainage pipe, a water supply pipe and a heat exchange mechanism. The floor drain is connected to one end of the drainage pipe. The water supply pipe is used to supply water to a water heater for showering. The heat exchange mechanism includes a shell. The body is arranged into a preset groove on the floor of the shower room. The top plate of the shell is the floor of the shower room. A heat exchange cavity is arranged inside the shell at the back of the top plate. The top plate is provided with multiple through holes; A section of the water supply pipe is arranged in the heat exchange cavity; the floor drain is arranged on the bottom surface of the heat exchange cavity. The integrated heat recovery floor device provided by the present invention uses the top plate of the heat exchange mechanism as the floor of the shower room, and directly opens holes on the floor to drain waste water for direct heat exchange under the floor, which greatly shortens the waste water heat exchange time. Therefore, the overall size of the heat exchange mechanism is reduced, thereby solving a series of problems caused by the excessive size of the heat exchange mechanism.

Description

technical field [0001] The invention relates to building environmental protection technology, in particular to an integrated heat recovery floor device. Background technique [0002] Generally speaking, the temperature of the waste water from the shower is higher than 35 degrees Celsius. In order to make full use of this heat energy, in the prior art, this part of the heat is recovered through the waste heat recovery system of the residential toilet. The water and the hot waste water from the shower are exchanged through a heat exchanger, thus recovering heat energy. [0003] Compared with other fluid heat exchanges, the waste heat recovery system in residential bathrooms is also difficult because the heat exchanger needs to occupy a certain amount of space. How to arrange the heat exchanger has become a technical pain point. There are two main ways for this arrangement in the existing technology. For example, the authorized announcement number is CN206448560U, and the auth...

AI Technical Summary

Problems solved by technology

At present, the toilets of most families are not spacious. For example, in the above-mentioned first method, arranging a heat exchanger in addition to the water heater, shower head, etc. makes the toilet, especially the shower part, quite crowded. high, it is also necessary to arrange a water pump to suck the low-level waste water into the heat exchanger, which involves problems such as anti-blocking and pipeline layout; and the above-mentioned second method, on the one hand, the shower unit and the toilet unit and washing The different heights of the units make it inconvenient to use the bathroom, and the structure is also nondescript. On the other hand, the height of the floor is limited, and the height of the shower part also makes the shower space smaller, which brings inconvenience to the shower

[0004] The root cause of the dilemma of heat exchanger layout in the prior art is that in the fluid heat exchange technology in the prior art, the heat exchanger generally uses a long-stroke shell side and a repeatedly bending and reciprocating tube side for heat exchange, which makes The size occupied by the heat exchanger is too large

In the heat exchange of shower wastewater, the heat exchanger of this structure also brings another problem, that is, the shower wastewater is rich in cortex and dirt, and the warm environment after the shower makes bacteria multiply and brings hygiene problems. and clogging issues

[0005] The disadvantage of the existing technology is that the heat exchange structure of the heat exchanger causes it to occupy too much space. If the characteristics of the bathroom shower can be considered and a heat exchanger with a small space occupation and a large heat exchange area can be designed, it will certainly solve the problem. The above series of questions
