Detailed Description

The present invention will be further explained with reference to the drawings attached to the specification.

Fig. 1 shows an energy-saving water heater, which includes a housing 300, an energy-saving recovery device 100 and a water heater, wherein the energy-saving recovery device and the water heater are located in the housing. The energy-saving water heater is particularly suitable for occasions such as shampoo shops and the like which frequently use hot water. Taking a hair washing shop as an example, hot water in hair washing is quickly lost, so that a large amount of heat energy is wasted, and the energy-saving water heater can recycle part of heat lost from the hot water, so that the utilization rate of heat is improved, and energy conservation is realized.

The energy-saving recovery device 100 comprises a coil 101, a wastewater inlet 102 for introducing wastewater to be sprayed on the coil, and a wastewater outlet 103 for discharging the wastewater, wherein a water distribution disc 104 is arranged above the coil, the water distribution disc 104 is connected with the wastewater inlet 102, and water distribution grooves are distributed on the periphery of the water distribution disc 104 to spray the wastewater in the water distribution disc on the coil. One end of the coil 101 is provided with a cold water inlet 105, and the other end of the coil is connected to a water heater via a water tank 200. Wherein the coil pipe is circularly wound for a plurality of circles.

In structural configuration, water tank 200 is surrounded by coil pipe 101, and the waste water that drenches down when can utilizing the coil pipe heat exchange keeps warm to the water tank, avoids the temperature of water in the water tank to reduce fast. The water heater is located outside the coil.

The waste water inlet 102, the waste water outlet 103, the cold water inlet 105, and the hot water outlet 400 are exposed outside the housing 300 so as to be connected to the pipes. In order to facilitate assembly and maintenance of the internal structure, the housing may be an assembled structure, such as a top cover 301, a bottom plate, and side plates, which can be separately disassembled.

The waste water inlet is used for flowing in used waste water such as sewage of a connecting counter basin, the waste water outlet is connected with a waste water drainage pipeline, and the cold water inlet is connected with a tap water connector. The shell is also provided with a hot water outlet connected with the water heater, and the hot water outlet is connected with the shower head.

When water is used, the shower head is opened to output hot water, at the moment, tap water supplies water into the coil pipe 101 through the cold water inlet 105, the hot water flowing out of the shower head flows to the water distribution disc 104 through the waste water inlet 102 after being used and is sprayed to the coil pipe 101 through the water distribution groove, partial heat is transferred to the cold water flowing through the coil pipe, the cold water flowing through the coil pipe is heated into preheated water, and heat recovery is achieved. The preheated water enters the water tank 200 and is then heated in the water heater to a desired water temperature for use. During the water using period, the cold water obtains heat from the waste water and is heated, so that when the cold water is heated to the expected water temperature by the water heater, the effect of second heating (outlet water is hot water) can be realized more quickly and more energy-saving.

As shown in fig. 1-3, in order to ensure that the wastewater is uniformly and sufficiently sprayed on the coil pipe and avoid blocking and overflowing on the basis, the water diversion disc is made into a disc shape, water diversion grooves are distributed on the edge of the water diversion disc, the illustrated disc-shaped water diversion disc is adaptive to the coiling shape of the coil pipe, and in specific implementation, the water diversion disc can be in an oval shape, a square shape and the like according to the coiling shape of the coil pipe. Specifically, the water diversion tank comprises a first water diversion tank 106 and a second water diversion tank 107 which are arranged at intervals, and the bottom of the first water diversion tank is lower than that of the second water diversion tank. When the water diversion plate works normally, wastewater is only shunted through the first water diversion groove, and when the first water diversion groove is blocked and the water level in the water diversion plate rises, wastewater is shunted through the second water diversion groove, so that overflow is avoided. In addition, if the flow of the wastewater is large, the wastewater can be simultaneously shunted through the first water diversion tank and the second water diversion tank.

Further, the first water dividing groove 106 has a first water dividing opening 108 at the edge of the water dividing disc through which the water flows downward, and the second water dividing groove 107 has a second water dividing opening 109 at the edge of the water dividing disc through which the water flows downward, and the first water dividing opening is smaller than the second water dividing opening. Therefore, when the first water diversion groove is blocked, the water can be quickly diverted through the second water diversion groove.

And, the center part of the water distribution tray is provided with an overflow hole 110. The upper end opening of the overflow hole is higher than the bottom of the second water dividing groove. When the second water dividing tank is also blocked, the stored water in the water dividing disc can be discharged through the overflow hole, so that the overflow caused by the transition rise of the water level in the water dividing disc is avoided.

In order to facilitate the connection with the waste water inlet, the edge of the water diversion plate is provided with a water inlet 111, and the waste water inlet 102 is connected with the water inlet 111. The central part of the water distribution disc is provided with a buffering bulge 112 corresponding to a water flow inlet, when wastewater flows in, the buffering bulge buffers the inflowing wastewater, so that the water level in the water distribution disc is uniform, and the uniform water distribution is ensured.

As shown in fig. 4-5, in view of the structure of the water diversion disc, a step 302 is provided in the housing, the water diversion disc 104 is placed on the step 302, the periphery of the water diversion disc is circumferentially positioned by the inner wall of the housing, and the size of the first water diversion opening and the size of the second water diversion opening are determined.

In order to facilitate assembly and disassembly, the top cover is assembled with the shell through the buckling structures 303, and the bottom plate and the side plates can also be assembled with the shell through the same buckling structures or similar structures.
