For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] Below is the attached figure Figures 1 to 4 The technical solution of the present invention is further illustrated by specific implementation methods.

[0026] like Figure 1-4As shown, a shower room with heat recovery function comprises a shower room body 1, a cold water pipe 3, a spray device 4 and a water source heat pump. A preheating box 2 is installed on the inner wall of the shower room body 1. A heat exchange tube 21 is arranged inside the preheating box 2. The water inlet end of the heat exchange tube 21 is connected to the cold water pipe 3, the water outlet end of the heat exchange tube 21 is connected to the water inlet end of the water source heat pump, and the water outlet end of the water source heat pump is connected to the hot water end of the spray device 4.

[0027] The inner bottom wall of the shower room body 1 is installed with a waste pipe 5, the bottom end of the waste pipe 5 is connected with an insulation box 53, the inner bottom end of the preheating box 2 is respectively connected with a first recovery pipe 22, a second recovery pipe 23 and a drain pipe 24, the bottom end of the first recovery pipe 22 is connected with the top of the insulation box 53, the bottom end of the second recovery pipe 23 is connected with the side wall of the waste pipe 5, and the first recovery pipe 22 and the second recovery pipe 23 are respectively installed with water pumps;

[0028] A second electrically controlled valve is installed inside the drain pipe 24, a first temperature sensor 28 is installed on the inner wall of the preheating box 2, and a controller is installed outside the preheating box 2. The controller is electrically connected to the second electrically controlled valve and the first temperature sensor 28 through wires.

[0029] Specifically, in the initial state, the second electrically controlled valve is in a closed state, and the waste hot water generated during bathing flows into the waste pipe 5, and part of the waste hot water in the waste pipe 5 flows into the heat preservation box 53 for storage. At the same time, under the action of the water pump, part of the waste hot water in the waste pipe 5 is pumped into the preheating box 2 through the second recovery pipe 23, and the cold water enters the heat exchange tube 21 through the cold water pipe 3. The waste hot water heats the cold water in the heat exchange tube 21, and the heated cold water enters the water source heat pump, and then is heated by the water source heat pump and transported to the hot water end of the spray device 4, thereby recycling the heat of the waste hot water. Furthermore, during the heating process, the temperature of the waste hot water is monitored by the first temperature sensor 28. When the temperature of the waste hot water is too low to heat the cold water in the heat exchange tube 21, the second electrically controlled valve is opened to discharge the waste hot water in the preheating tank 2 to the outside through the drain pipe 24. After the waste hot water is completely discharged, the second electrically controlled valve is closed. Then, under the action of the water pump, the waste hot water in the insulation tank 53 is pumped into the preheating tank 2 through the first recovery pipe 22 to continue heating the cold water in the heat exchange tube 21, thereby increasing the temperature of the cold water entering the low water source heat pump and reducing the energy consumption of the water source heat pump.

[0030] like Figure 2 As shown, a guide rod 25 is vertically installed on the inner bottom wall of the preheating box 2, and a floating block 252 is provided on the external sliding sleeve of the guide rod 25. A contact switch 251 is fixedly connected to the top of the guide rod 25, and the contact switch 251 is electrically connected to the controller through a wire.

[0031] Specifically, as the liquid level of the waste hot water in the preheating tank 2 rises, the waste hot water will drive the float 252 to move upward until the float 252 contacts the contact switch 251. At this time, the preheating tank 2 is full of waste hot water, and the controller will turn off the water pump to prevent the waste hot water from continuing to flow into the preheating tank 2.

[0032] like Figure 3 As shown, the bottom end of the waste pipe 5 is also connected to a water outlet pipe 52, and a first electrically-controlled valve is installed inside the waste pipe 5. The first electrically-controlled valve is used to control the connection between the waste pipe 5 and the water outlet pipe 52 and the insulation box 53. A second temperature sensor 51 is installed on the inner wall of the waste pipe 5. The first electrically-controlled valve and the second temperature sensor 51 are electrically connected to the controller through a wire.

[0033] Specifically, in the initial state, the waste pipe 5 is connected to the insulation box 53. When cold water is used in the shower room body 1, the cold water flows into the waste pipe 5. The second temperature sensor 51 can monitor that the temperature of the water in the waste pipe 5 is low. At this time, the first electrically controlled valve is opened to connect the waste pipe 5 with the water outlet pipe 52, and the cold water is discharged through the water outlet pipe 52, avoiding the cold water from flowing into the insulation box 53 and lowering the temperature of the waste hot water in the insulation box 53. The water pump does not work, thereby reducing the energy consumption of the device.

[0034] like Figure 2 As shown, the first electrically-controlled valve and the second electrically-controlled valve are solenoid valves.

[0035] Specifically, the solenoid valve can be conveniently connected to a computer or an automatic control system to achieve remote control and automatic control to meet the use requirements of the device.

[0036] like Figure 3 As shown, the waste pipe 5 is a three-way pipe.

[0037] Specifically, the waste pipe 5 adopts a three-way pipe, which can facilitate the waste pipe 5 to be connected with the insulation box 53 and the water outlet pipe 52.

[0038] like Figure 2 As shown, the top cover of the preheating box 2 is provided with a sealing cover 27 , and the bottom of the sealing cover 27 is provided with a sealing rubber plate 26 that is tightly attached to the inner wall of the preheating box 2 .

[0039] Specifically, the top of the preheating box 2 can be conveniently sealed by the sealing cover 27 and the sealing rubber plate 26, and when the internal parts of the preheating box 2 are damaged, the sealing cover 27 can be conveniently opened for maintenance.

[0040] like Figure 4 As shown, a filter mesh sleeve 51 is detachably mounted on the inner top of the waste discharge pipe 5 .

[0041] Specifically, since the hot waste water generated by bathing contains a lot of hair, in order to prevent the hair from clogging the device, the hair in the water can be filtered through the provided filter mesh sleeve 51 to increase the service life of the device, and the detachable installation method can facilitate the removal of the filter mesh sleeve 51 for cleaning.

[0042] The technical principle of the present invention is described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanations herein, those skilled in the art can associate other specific implementations of the present invention without paying creative labor, and these methods will fall within the scope of protection of the present invention.
