[Prior Art] Hot water is used in industry or home, and most industrial or domestic wastewater is directly discharged. In the hot waste water, considerable heat is still stored. For example, most of the hot water discharged during bathing or bathing in the home is discharged directly from the pipeline to the sewer to form wastewater. There is almost no second resource utilization. However, the bathing water is firstly heated by cold water. To the temperature suitable for bathing (about 4〇~60.〇; the water absorbs the heat during the heating process, but the heat is not completely released during the bathing process). If the waste hot water is directly discharged, it will not be reused. It is not only a waste of water resources. It also wastes the heat energy stored in the water during heating. It is very inconsistent with environmental protection requirements. Therefore, the heat energy recovery and reuse of waste hot water is currently the same as Japan’s Dilu JP2005055051, JP2005009810 and JP2005030758. In the patent case, it is a method of reusing thermal energy of waste hot water. The temperature sensor is used to control the temperature of the hot water of the system, and the remaining heat energy of the waste hot water is reused. However, these methods are directly targeted. The hot water is raised in temperature, so it is necessary to consume a considerable amount of heat energy, and the temperature is not efficiently improved, so it is used. [Invention] 317351 The main object of the present invention is to provide a method for reusing thermal energy of waste hot water, which is used to solve the problem that the heat energy cannot be recycled again after the conventional waste water is discharged. As follows: (a) Place the cooling fins in the area where the waste hot water is located or in the area where it passes. (b) Work on the cooling fins. (c) Use the cold contact surface of the cooling fins to absorb the heat of the waste hot water. _ (d) The thermal contact surface of the cold piece releases heat energy. (e) Reusing the above-mentioned heat energy. The area where the waste hot water is located is the area where the waste hot water is stored; the area where the waste hot water passes is the pipe for conveying the waste hot water. In the insulated pipe, the heat energy is avoided. (e) Reusing the above heat energy means directly using heat energy, for example, transferring heat energy to a temperature in a specific space in the air; or transferring heat energy to other media. Reuse, for example, the use of thermal energy as a preheating use of water. The present invention has the following significant advantages: 1. The present invention can recover the thermal energy of the discharged waste hot water, and the thermal energy can be converted to Reuse of other media, for example, the heat energy can be used to preheat the hot water to be heated for bathing in the home to reduce the amount of fuel required. 2. The hot and cold sides of the cold plate provide effective heat exchange, ie, the cold film The cold contact surface can effectively absorb the heat energy of the waste hot water; and the thermal contact surface of the cooling sheet can transfer heat energy to other medium to be heated. The heating unit (1) is provided with an inlet pipe (11) and an outlet pipe (12) The cold water can be sent from the inlet pipe (11) to the heating unit (1) for heating to form hot water, and then sent out by the outlet pipe (12), which is set as a thermally conductive metal pipe. The first discharge line (2) is a heat-conducting metal pipe body, the pipe end is provided with a collecting tank (21), and the thief section pipe is covered with a secret temperature material (22). The other end of the tube is preferably in contact with the inlet pipe of the heating pipe (1) of the heating unit (1), and the pipe section of the contact end is preferably formed as a square pipe. The temperature control valve (4) is provided with a temperature sensor (41) and a control valve (42), which can be disposed on the first discharge line (2). The second discharge line (5)' is externally connected to the control valve (42). The cooling plate (6) is disposed between the inlet pipe (π) and the first discharge pipe (2) contact surface, and the cooling plate (6) has a higher temperature contact surface (61). The inlet pipe (11) is in contact, and the lower temperature cold contact surface (62) is in contact with the first discharge line (2). If the cold water is fed from the inlet pipe (11) of the heating unit (1) and heated to become hot water, it is then sent out by the outlet pipe (12) for bathing, and is passed through the first discharge pipe (2). The collecting tank (21) first collects water; if the waste hot water is discharged, the waste hot water will be sent out by the first discharge line (2), and since the first discharge line (2) is provided with the heat insulating material (22), Ensure that the thermal energy of the waste hot water discharged from the first discharge line (2) is not lost during the discharge; if the waste hot water passes through the temperature control valve (4), the temperature sensor in the temperature control valve (4) (41) The temperature of the hot water in the first discharge line (2) will be measured first. Once the temperature of the waste hot water is above the predetermined temperature value of 1313751, then the waste hot water will be circulated by the first discharge line (2). Heating the inlet of the inlet pipe (11) of the single crucible (1), so that the thermal energy of the waste hot water can be collected through the first discharge pipe (2) after passing through the inlet pipe ((1), due to the appropriate working current of the cooling fin (6) , the cooling piece (6) can be kept in working state, that is, the cooling piece (6) has a cold contact surface at this time. (62) Contact with the hot surface (61). When the hot water in the first discharge line (2) is in contact with the cooling plate (6), the cold contact surface (62) having a lower temperature is allowed to absorb the heat energy sufficiently and rapidly. And releasing heat energy at a relatively high temperature thermal contact surface (61), so that it can be fed to the water inlet pipe ((1) preheating the water conveyed by the sacrificial water to save the heating energy required by the heating unit (1) and improve its efficiency. On the contrary, if the temperature of the waste hot water is judged to be insufficient by the temperature control valve (4) to make the inlet pipe of the heating unit (1) (the temperature of the cold water in (1) rises, the temperature control valve (4) will be opened. The second discharge line (5) causes the waste heat to be dissipated by the second discharge line (5) without causing the lower temperature of the waste hot water to lower the temperature of the water in the inlet pipe (ιι). 1) The cold water flowing into the inlet pipe (11) will be preheated through the hot contact surface (61) of the cooling fin (6) on the first discharge line (2), so that the cold water temperature is slightly increased after the 'new feed plus fresh element (1) Heating, recirculation from the outlet pipe (12), so that the heating unit (1) will save the cost of heating Energy, as a result, the thermal energy of the waste hot water - reused again, will greatly save energy for long-term use. However, the above is only a preferred embodiment of the present invention, except that it can be applied to In addition to the reuse of hot water, the heat can be used to heat the heat to the other devices that require heat, and is not limited to the use of pure hot water recovery heat. The scope of the present invention may not be limited thereby, that is, the simple equivalent changes and modifications made by the contents of the book and the contents of the book are still within the scope of the patent of the present invention.
