Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, an energy-saving washing device utilizing wastewater heat from clothing treatment includes a water storage tank 1. The water storage tank 1 has a first inlet 11 and a first outlet 12. A treatment tank 13 is located on the side wall of the water storage tank 1. A second outlet 14 is located on the side wall of the treatment tank 13. The water storage tank 1 and the treatment tank 13 are connected by a heat-conducting plate 15. Multiple heat-absorbing sheets 16 are fixed to the side wall of the heat-conducting plate 15. The heat-absorbing sheets 16 are arranged through the treatment tank 13. The surface of the treatment tank 13... A second water inlet 17 is provided. During operation, wastewater is first transferred to the treatment tank 13 through the second water inlet 17 connected to a drainage pipe. Upon entering the treatment tank 13, the wastewater first contacts the heat-absorbing fins 16, which absorb heat from the wastewater and transfer it to the heat-conducting plate 15. This heats the water entering the storage tank 1. Then, the first water inlet 11 is connected to the inlet to supply water into the storage tank 1. When the storage tank 1 is full, the first water inlet 11 is closed. After disconnecting the connecting pipe, connect the first inlet 11 and the first outlet 12 to the heat exchanger. Simultaneously, connect the second outlet 14 to the heat exchanger inlet via a water pump. Start the pump to send the wastewater from the treatment tank 13 into the heat exchanger through the second outlet 14. At the same time, transfer the water from the storage tank 1 into the heat exchanger. Once both water sources enter the heat exchanger, the heat from the wastewater will continuously heat the water in the storage tank 1, gradually carrying away the heat from the wastewater. After being heated, the wastewater leaves the heat exchanger and returns to the water storage tank 1 through the first outlet 12. At the same time, the wastewater is discharged through the outlet of the heat exchanger. Thus, the residual heat of the wastewater inside the treatment tank 13 is used to heat the water source inside the water storage tank 1. By using a heat-conducting plate 15 to connect the water storage tank 1 and the treatment tank 13, the heat absorbed by the heat-absorbing plate 16 after the wastewater enters the treatment tank 13 can be transferred to the water storage tank 1 through the heat-conducting plate 15, thus initially heating the water source and accelerating the heating speed of the water source, thereby reducing the heating time when using the water source.

[0026] like Figures 1 to 2 As shown, the side wall of the treatment tank 13 is connected to a vacuum pump 2; the side wall of the vacuum pump 2 is connected to an exhaust pipe 21; the exhaust pipe 21 and the water storage tank 1 are connected; during operation, because the wastewater contains heat, it will be accompanied by hot air after entering the treatment tank 13. At this time, the vacuum pump 2 is started, so that the vacuum pump 2 extracts the hot air inside the treatment tank 13 and transfers it to the water storage tank 1 through the exhaust pipe 21. When the hot air enters the water storage tank 1, it will heat the water source inside the water storage tank 1, thereby accelerating the heating of the water source; by adding the vacuum pump 2, the hot air inside the treatment tank 13 can be extracted into the water storage tank 1, thereby using the hot air to heat the water source inside the water storage tank 1, thereby accelerating the heating rate of the water source.

[0027] like Figure 2 As shown, multiple heat sinks 3 are fixed to the side wall of the heat-conducting plate 15; the heat sinks 3 are arranged through the water storage tank 1; during operation, after the heat-absorbing plate 16 absorbs heat and transfers it to the heat-conducting plate 15, the heat-conducting plate 15 will transfer the heat to the inside of the heat sink 3. At this time, the heat sink 3 will be in full contact with the water source inside the water storage tank 1, thereby accelerating the heating of the water source inside the water storage tank 1; by adding heat sinks 3, the contact area with the water source can be increased when the heat-conducting plate 15 heats the water source inside the water storage tank 1, thereby reducing the heating time and making it reach the operating temperature faster, thus accelerating the heating speed.

[0028] like Figures 2 to 4 As shown, multiple round rods 4 are fixed to the inner wall of the treatment tank 13; multiple elastic rods 41 are fixed to the surface of the round rods 4; during operation, when wastewater is transferred through the second outlet 14, the wastewater will first come into contact with the elastic rods 41. At this time, the elastic rods 41 will intercept the impurities inside the wastewater and keep them on the surface of the elastic rods 41, thereby reducing the amount of impurities entering the heat exchanger; by adding elastic rods 41, the wastewater can be filtered by the elastic rods 41 as it moves, thereby reducing the impact on the heat exchanger after the wastewater is transferred.

[0029] like Figures 4 to 5 As shown, the water storage tank 1 has multiple rings 5 ​​inside; a support rod 51 is fixed to the top of each ring 5; multiple cleaning rods 52 are fixed inside each ring 5; the rings 5 ​​and the rods 4 are arranged correspondingly; during operation, when the elastic rod 41 is blocked for a long time, a large amount of impurities will appear on its surface. At this time, pulling the support rod 51 causes the support rod 51 to move the ring 5 upward. When the ring 5 moves upward, the cleaning rod 52 will come into contact with the impurities wrapped around the surface of the elastic rod 41, thereby peeling them off the surface of the elastic rod 41 and cleaning the surface of the elastic rod 41; by adding cleaning rods 52, the elastic rod 41 can be cleaned after being blocked for a long time, thereby reducing the impurities wrapped around the surface of the elastic rod 41 and reducing the impact of impurities on the elastic rod 41.

[0030] like Figures 3 to 4 As shown, multiple locking blocks 6 are fixed to the inner wall of the treatment box 13; the locking blocks 6 have slots 61 inside; the slots 61 and the support rods 51 are correspondingly arranged; during operation, when the ring 5 is installed into the treatment box 13, the support rods 51 can be aligned with the slots 61 and inserted into the inside. When the support rods 51 enter the slots 61, they will be restricted by the slots 61, thereby reducing the movement caused by the impact of water flow; by adding slots 61, support can be provided for the support rods 51, making them more stable.

[0031] Working principle: Wastewater is first transferred to the treatment tank 13 by connecting the second inlet 17 to the drain pipe. Upon entering the treatment tank 13, the wastewater first contacts the heat-absorbing fins 16, which absorb heat from the wastewater and transfer it to the heat-conducting plate 15. This heats the water entering the storage tank 1. Then, the first inlet 11 is connected to the inlet to supply water to the storage tank 1. When the storage tank 1 is full, the pipe connected to the first inlet 11 is disconnected. The first inlet 11 and the first outlet 12 are then connected to the heat exchanger, while the second outlet 14 is used to supply water. The pump is connected to the inlet of the heat exchanger. Starting the pump sends wastewater from treatment tank 13 into the heat exchanger through the second outlet 14, simultaneously transferring water from storage tank 1 to the heat exchanger. As both water sources enter the heat exchanger, the heat in the wastewater continuously heats the water in storage tank 1, gradually carrying away the heat. The heated wastewater then leaves the heat exchanger and returns to storage tank 1 through the first outlet 12. Meanwhile, the wastewater is discharged through the heat exchanger's outlet. This process utilizes the residual heat of the wastewater in treatment tank 13 to heat the water in storage tank 1. Because the wastewater contains heat... Upon entering the treatment tank 13, hot air is introduced. The vacuum pump 2 is then activated, drawing the hot air from the treatment tank 13 and transferring it through the exhaust pipe 21 to the water storage tank 1. This hot air heats the water inside the tank, accelerating the heating process. After the heat-absorbing fin 16 absorbs heat and transfers it to the heat-conducting plate 15, the heat is transferred to the heat sink 3. The heat sink 3 then comes into full contact with the water inside the water storage tank 1, further accelerating the heating process. When the wastewater is discharged through the second outlet 14, it first contacts the elastic rod 41. The system intercepts impurities inside the wastewater, causing them to remain on the surface of the elastic rod 41, thus reducing their entry into the heat exchanger. After prolonged interception, a large amount of impurities will appear on the surface of the elastic rod 41. At this time, pulling the support rod 51 causes the ring 5 to move upward. As the ring 5 moves upward, the cleaning rod 52 will come into contact with the impurities wrapped around the surface of the elastic rod 41, thereby peeling them off the surface of the elastic rod 41 and cleaning the surface of the elastic rod 41. When the ring 5 is installed inside the treatment box 13, the support rod 51 can be aligned with the slot 61 and inserted inside. After the support rod 51 enters the slot 61, it will be restricted by the slot 61, thus reducing movement caused by water flow impact.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
