[0002] With the development of the economy and society and the continuous improvement of people's living standards, the demand for thermal comfort in home and work environments is increasing. Therefore, a large number of heating equipment have been launched on the market, such as air conditioners, heaters, electric heaters, industrial furnaces, steam boilers and multi-purpose heating machines.

[0003] Multi-purpose integrated heating machines are often used in factories. Many production processes in the factory require heat, and the factory has good heat production conditions. In addition, factory workshops, offices, dormitories, etc. need heating in winter, and workshop workers also need to take a shower after get off work. Heating is an indispensable task in the factory.

[0004] The multi-purpose integrated heating machine can not only meet the heat needs of the process, but also take into account the heating and shower needs. However, when the multi-purpose integrated heating machine provides heat for the shower system, there will be residual hot water in the water supply pipe. The residual hot water will turn into cold water and remain in the pipe after being left for a long time. When the water is supplied again, the cold water will be discharged first. If you use cold water to rinse first, it is easy to cause cramps and increase the burden on the heart. Due to the residual cold water in the pipe, you need to wait for the cold water to be drained before you can release hot water to take a shower, which leads to a large amount of water resources in the factory.

The user only needs to connect the steam heat source, the heating system and the feed water pipe, and connect the power supply to put it into use. Please refer to the attached Figure 1 The five systems are explained in detail. Figure 1 shall prevail;

[0030] 1. Heat source and water tank heat exchange circulation system: 2.1MPa 230℃ superheated steam from heat source passes through stop valve 1, Y-type filter 2, electric regulating valve 3 to enter tube heat exchanger 4 for heat exchange. After cooling, condensed water is discharged into the low-temperature end of hot and cold water tank 401 through the drain system composed of drain valve 6, stop valve 7, vacuum breaker 8, etc. The low-temperature water in the water tank passes through Y-type filter 10 and circulation system 11 composed of circulation pump, metal flexible joint, check valve, butterfly valve, frequency conversion control system, etc., and is drawn into tube heat exchanger 4 for heat exchange. The heated hot water enters the high-temperature end of hot and cold water tank 401 through butterfly valve 5.

[0031] The above constitutes a heat exchange circulation system between the heat source and the water tank. The temperature in the water tank is measured by the temperature transmitter 32. The opening of the electric regulating valve 3 is adjusted according to the measured temperature to control the flow of steam entering the shell and tube heat exchanger, thereby achieving the purpose of constant water temperature in the water tank;

[0032] The circulation system 11 has a frequency conversion control function. When the water temperature is low, the dual pumps run at full load. When the temperature is about to reach the set value or a large amount of heat exchange is not required, it can be switched to single pump operation and the water pump operation frequency can be reduced to maintain a constant water temperature in the water tank. In addition, the system has a low liquid level protection function. The liquid level is detected by the liquid level meter 33. If the liquid level is lower than the set value, the circulation pump cannot be started, and the solenoid valve 31 is opened to replenish the water tank.

[0033] 2. Heating circulation system: The heating system provides heat source to the plate heat exchanger 13 through the circulation system 12 composed of a circulation pump, a metal flexible joint, a check valve, a butterfly valve, a frequency conversion control system, etc. After heat exchange, the hot water returns to the low-temperature end of the hot water storage tank through the butterfly valve 14 and the pipeline;

[0034] Cold water from the user end enters through the butterfly valve 15, passes through the Y-type filter, and the circulation system 16 composed of a circulation pump, a metal flexible joint, a check valve, a butterfly valve, etc., and is injected into the plate heat exchanger 13 for heating. The hot water flows out through the pipeline and the butterfly valve 17 and enters the user's heating building pipe network. The cold end water replenishment constant pressure is taken care of by the high-level water tank on the roof, realizing the pressure stabilization and automatic water loss replenishment functions;

[0035] The circulation system 12 is controlled by a frequency converter. The water supply temperature is measured by a temperature transmitter 34. After internal comparison by the programmable controller, PID adjustment is performed to increase or decrease the circulation pump frequency to achieve the purpose of maintaining a constant water supply temperature. In addition, the pressure transmitter 35 and the temperature transmitters 34 and 36 can monitor the supply and return water pressure and temperature in real time and upload them to the user's main control center.

[0036] 3. Shower system: The shower system provides heat source to the instantaneous semi-volumetric heat exchanger 103 through the circulation system 19 composed of a circulation pump, a metal flexible joint, a check valve, a butterfly valve, a frequency conversion control system, etc. After the heat exchange, the hot water returns to the low-temperature end of the hot water storage tank through the butterfly valve 21 and the pipeline;

[0037] Cold water from the user end enters through the ball valve 21, passes through the Y-type filter and the check valve, and enters the instantaneous semi-volumetric heat exchanger 103 for heating. The instantaneous semi-volumetric heat exchanger has heat storage and constant temperature functions. When the user needs water, the circulation system 22 composed of a circulation pump, a metal flexible joint, a check valve, a butterfly valve, a frequency conversion control system, etc. is opened to provide hot water to the shower system through the ball valve 23;

[0038] The circulation system 19 is controlled by a frequency converter, and the water supply temperature is measured by a temperature transmitter 37. After internal comparison by the programmable controller, PID adjustment is performed to increase or decrease the circulation pump frequency to achieve the purpose of keeping the water supply temperature constant. The circulation system 22 is controlled by a frequency converter, and the water supply network pressure value is measured by a pressure transmitter 38. After comparing the set value through the controller, the water pump frequency is adjusted to control the water pump speed to achieve the purpose of constant pressure water supply.

[0039] 4. Process water circulation system: The process water system provides hot water to the piperazine chemical tank, dryer, heating of various storage tanks, etc. in the production process through the circulation system 25 composed of a circulation pump, a Y-type filter, a metal flexible joint, a check valve, a butterfly valve, a frequency conversion control system, etc. After the heating of each part is completed, the low-temperature water is returned to the low-temperature end of the water tank after the pressure is adjusted by the pressure reducing valve 27;

[0040] The circulation system 25 is controlled by a frequency converter, and the pressure value of the water supply network is measured by a pressure transmitter 39. The water pump frequency is adjusted by the controller after comparing with the set value, and the water pump speed is controlled to achieve the purpose of constant pressure water supply. At the same time, a pressure regulating tank 25 is configured. After the pressure value reaches the set value, the circulation water pump is turned off to stabilize the system pressure under small pressure fluctuations to avoid frequent start and stop of the water pump. When the process system needs water, the circulation pump is turned on to supply water.

[0041] 5. Water replenishment system: The water replenishment system is responsible for replenishing water to the shower system and the heat storage tank. The heating system is replenished by the high-level water tank. The tap water passes through the stop valve 28, the Y-type filter 29, the remote water meter 30, the solenoid valve group 31, the liquid level sensor 33, etc. When the shower system loses water, the system is automatically replenished with water. When the water level in the water tank is lower than the set value, the solenoid valve group is opened for water replenishment. It has the functions of uploading water consumption and automatic water replenishment.

[0042] The following is the attached Figure 2-6 Explain the working status of the shower system of the multi-purpose heating machine. Figure 2-6 shall prevail;

[0043] When the shower system of the multi-purpose heating machine is working, firstly, the first water pump 102 cooperates with the water inlet pipe 101 to pump cold water, and the cold water is sent to the semi-volumetric heat exchanger 103 for heat exchange. The semi-volumetric heat exchanger 103 is provided with heat source by the heat source and the water tank heat exchange circulation system. The heat source heats the cold water sent into the semi-volumetric heat exchanger 103. At this time, the electric slider drives the diverter block 108, which originally cooperates with the bellows 112 to connect the first check valve 106, to slide close to the first water temperature sensor 111, and the diverter Block 108 slides and squeezes bellows 112 to shrink, and the flow control component closes the channel to No. 1 check valve 106. The bottom channel of diverter block 108 corresponds to the top channel of No. 2 check valve 110. No. 1 water pump 102 pumps the hot water generated by cold water heat exchange into No. 1 hot water pipe 104. Due to the cold water previously retained in No. 1 hot water pipe 104, the hot water mixes and pushes the retained cold water to be transported into diverter block 108. The retained cold water passes through No. 1 water temperature sensor 111 and enters the diverter block. 108, the cold water falls into the No. 1 return pipe 109 through the bottom channel of the diverter block 108, and the remaining cold water flows back to the water inlet pipe 101 for circulation and heating, thereby reducing the waste of water resources. At the same time, after the No. 1 water temperature sensor 111 detects that the hot water transported in the No. 1 hot water pipe 104 has reached the set shower temperature, the electric slider drives the diverter block 108 to slide close to the No. 1 check valve 106. After the bottom channel of the diverter block 108 is misaligned with the top channel of the No. 2 check valve 110, the diverter block 108 is connected to the No. 1 check valve 106. The inner wall of box 105 blocks the bottom channel of diverter block 108. As diverter block 108 slides close to the flow control component, the flow control component opens one side channel of one-way valve 106, and bellows 112 is pulled and extended by diverter block 108. Hot water enters No. 1 water temperature sensor 111, bellows 112, diverter block 108, flow control component and one-way valve 106 from No. 1 hot water pipe 104, and finally reaches outlet pipe 107 for discharge for showering, thereby providing heat to the shower system.

[0044] like Figures 2 to 6 As shown, the flow control assembly includes a fixed plate 201, a push plate 202, a rubber block 203, a rotating shaft 204, a blocking plate 205 and a matching block 206; the fixed plate 201 is fixedly connected to the side of the No. 1 one-way valve 106 away from the water outlet pipe 107; the push plate 202 is fixedly connected to the top of the inner wall of the fixed plate 201; the rubber block 203 is fixedly connected to the upper surface of one end of the push plate 202 away from the fixed plate 201; the rotating shaft 204 is rotatably connected to the inner wall of the diverter block 108; the blocking plate 205 is fixedly connected to the rotating shaft 204; the matching block 206 is fixedly connected to the inner wall of the diverter block 108, and the matching block 206 is located below the rotating shaft 204, and the matching block 206 cooperates with the blocking plate 205 to block a single opening of the diverter block 108;

[0045] When the cold water in the diverter block 108 is controlled to flow back, the diverter block 108 slides with the electric slider to fit the No. 1 water temperature sensor 111, and the rotating shaft 204 drives the blocking plate 205 to rotate to cooperate with the matching block 206 to block the channel on one side of the diverter block 108 close to the fixed plate 201. The cold water is pumped from the No. 1 hot water pipe 104 into the No. 1 water temperature sensor 111 and reaches the diverter block 108, and flows into the No. 2 check valve 110 and the No. 1 return pipe 109 through the bottom channel of the diverter block 108. The cold water is finally sent back to the water inlet pipe 101 for circulation, which plays a role in recycling the cold water and reduces the waste of water resources.

[0046] When controlling the hot water shower in the diverter block 108, the No. 1 water temperature sensor 111 detects that the hot water delivered at this time meets the set temperature, and the electric slider drives the diverter block 108 to slide close to the fixed plate 201, the bellows 112 is pulled and stretched, and the protruding front end of the push plate 202 pushes the blocking plate 205, and the blocking plate 205 rotates with the rotating shaft 204. The bottom end channel of the diverter block 108 is blocked by the inner wall of the diverter box 105. When the diverter block 108 fits the outer wall of the fixed plate 201, the rubber block 203 elastically passes over the rotating shaft 204 and pushes the blocking plate 205 against the inner wall of the diverter block 108. The hot water delivered in the No. 1 hot water pipe 104 is sent to the outlet pipe 107 for showering through the No. 1 water temperature sensor 111, the bellows 112, the diverter block 108, the fixed plate 201 and the No. 1 one-way valve 106, which plays a role in heating the shower system.

[0047] like Figures 2 to 4 As shown, the top of the diversion box 105 is fixedly connected to an insulation box 301; the outer wall of the insulation box 301 is fixedly connected to a diversion check valve 302; the diversion check valve 302 is fixedly connected to a guide pipe 303, and the guide pipe 303 is connected to the water outlet pipe 107;

[0048] When taking a shower, the cold water in the No. 1 hot water pipe 104 is backflowed and there is a water flow gap. Hot water can be poured into the insulation box 301 in advance for storage. When the cold water in the No. 1 hot water pipe 104 flows back, the hot water is continuously transported to the insulation box 301. The hot water reaches the diversion check valve 302 and is discharged into the guide pipe 303. The guide pipe 303 then directly transports the hot water to the outlet pipe 107 for showering. After the No. 1 hot water pipe 104 is connected to the outlet pipe 107, the guide pipe 303 stops transporting hot water, which plays a role in replenishing hot water to fill the gap when the cold water in the No. 1 hot water pipe 104 flows back.

[0049] like Figure 2As shown, a hot and cold water tank 401 is arranged on the side of the semi-volumetric heat exchanger 103 away from the first water pump 102, and the hot and cold water tank 401 is composed of a high-temperature tank and a low-temperature tank; a water valve on the high-temperature tank of the hot and cold water tank 401 is fixedly connected with a water delivery pipe 402, and the water delivery pipe 402 is connected to an input end of the semi-volumetric heat exchanger 103; a second water pump 403 is fixedly connected to the water delivery pipe 402; a return water pipe 404 is fixedly connected between an output end of the semi-volumetric heat exchanger 103 and the low-temperature tank of the hot and cold water tank 401;

[0050] When the heat source is provided in the semi-volumetric heat exchanger 103 for heat exchange, the heat source is provided in the high-temperature tank of the hot and cold water tank 401 by the heat source and the water tank heat exchange circulation system, the high-temperature tank of the hot and cold water tank 401 stores hot water, and the low-temperature tank stores cold water and low-temperature water such as return water. The No. 2 water pump 403 pumps the hot water in the hot and cold water tank 401 through the water supply pipe 402, and the hot water enters the semi-volumetric heat exchanger 103 for heat exchange with the cold water pumped in the water inlet pipe 101. After heat exchange in the semi-volumetric heat exchanger 103, the cold water pumped into the water supply pipe 402 for heat exchange is sent to the low-temperature tank for storage by the return pipe 404, and the hot water pumped into the water inlet pipe 101 for heat exchange is sent to the shower by the No. 1 hot water pipe 104 for use, thereby playing a role in heat exchange with the cold water delivered by the water inlet pipe 101.

[0051] like Figures 2 to 4 As shown, the air valve on the high temperature box of the cold and hot water tank 401 is fixedly connected with an air guide pipe 501; the end of the air guide pipe 501 away from the cold and hot water tank 401 is fixedly connected with a three-way valve 502; the three-way valve 502 is respectively fixedly connected with a No. 1 steam distribution pipe 503 and a No. 2 steam distribution pipe 504, and the No. 1 steam distribution pipe 503 is fixedly connected between the three-way valve 502 and the semi-volumetric heat exchanger 103, and the end of the No. 2 steam distribution pipe 504 away from the three-way valve 502 is located above the insulation box 301; the end of the No. 2 steam distribution pipe 504 away from the three-way valve 502 is fixedly connected with a No. 3 check valve 505, and the No. 3 check valve 505 is fixedly connected to the top of the insulation box 301; the interior of the insulation box 301 is provided with an air cavity 506, and the air cavity 506 can be connected with the No. 3 check valve 505 and the No. 2 steam distribution pipe 504;

[0052] When the hot water retained in the insulated box 301 is easily cooled after being left for a long time, the hot air generated in the high temperature box of the hot and cold water tank 401 is transported to the three-way valve 502 for diversion through the air duct 501, and part of the hot air is sent to the hot water stored in the semi-volumetric heat exchanger 103 through the No. 1 steam pipe steam diversion pipe 503. The semi-volumetric heat exchanger 103 is a semi-volumetric device, so the semi-volumetric heat exchanger 103 has a space for storing hot water. After the hot air is sent into the semi-volumetric heat exchanger 103, the stored hot water can be kept warm, and the remaining hot air is sent into the air cavity 506 through the No. 2 steam diversion pipe 504 and the No. 3 one-way valve 505. The hot air insulates or heats the hot water in the insulated box 301 in the air cavity 506 to ensure the temperature of the water transported in the diversion pipe 303 when the cold water in the No. 1 hot water pipe 104 flows back.

[0053] A No. 2 hot water pipe 601 is fixedly connected to the top of the semi-volumetric heat exchanger 103; a No. 4 check valve 602 is fixedly connected to the end of the No. 2 hot water pipe 601 away from the semi-volumetric heat exchanger 103, and the No. 4 check valve 602 is fixedly connected to the side of the insulation box 301 away from the diversion check valve 302;

[0054] When the hot water stored in the insulated box 301 is used to supplement the idle period, the hot water stored in the semi-volumetric heat exchanger 103 is pumped out by the No. 1 water pump 102 through the No. 2 hot water pipe 601, and the hot water in the semi-volumetric heat exchanger 103 is sent into the insulated box 301 through the No. 4 check valve 602. The water level in the insulated box 301 rises, and the hot water originally at a liquid level below the diversion check valve 302 is injected through the No. 4 check valve 602 to raise the liquid level. The overflowing hot water is sent into the water outlet pipe 107 by the guide pipe 303 for use, thereby playing the role of replenishing hot water in the insulated box 301.

[0055] The interior of the diverter box 105 is fixedly connected with a water supply pipe 702, and the water supply pipe 702 can be connected to the interior of the heat preservation box 301; the bottom end of the water supply pipe 702 is fixedly connected with a No. 5 check valve 701;

[0056] When the hot water retained in the thermal insulation box 301 is overheated, the water temperature for human body shower should be gradually increased until it reaches a comfortable temperature. To replenish the hot water during the idle period, a small amount of cold water needs to be added for mixing to reach the temperature of warm water and improve the comfort of showering. The diverter block 108 is slidably fitted with the No. 1 water temperature sensor 111, and part of the cold water transported in the No. 1 hot water pipe 104 to be returned is diverted upward. Most of the cold water still flows back from the bottom channel of the diverter block 108. A small amount of cold water is sent from the top channel of the diverter block 108 through the No. 5 one-way valve 701 to the upper water pipe 702, and then sent to the thermal insulation box 301 by the upper water pipe 702 to mix with the hot water, thereby achieving the effect of mixing the cold water in the thermal insulation box 301 with warm water.

[0057] like Figures 2 to 4 , Figure 6As shown, the blocking plate 205 is fixedly connected to the side close to the first water temperature sensor 111 with the first guide block 801; the first guide block 801 is slidably connected to the inside with the second guide block 802, and an elastic member is fixedly connected between the second guide block 802 and the inner wall of the first guide block 801;

[0058] When the cold water transported back from the No. 1 hot water pipe 104 is diverted, the cold water enters the diverter block 108, and the cold water flushes the surface of the blocking plate 205. The first guide block 801 cooperates with the second guide block 802 to divert the flushed cold water, and a small amount of cold water is sent to the upper water pipe 702, and a large amount of cold water flows back to the water inlet pipe 101, which plays a role in diverting the refluxed cold water;

[0059] At the same time, when the sealing plate 205 is pushed by the push plate 202 to flip and fit the inner wall of the diverter block 108, the inner wall of the diverter block 108 squeezes the No. 2 guide block 802 to slide down and be stored in the No. 1 guide block 801, and the No. 2 guide block 802 squeezes the elastic part to shrink and bear the force, and the No. 1 guide block 801 is blocked at the top channel of the diverter block 108, thereby storing the No. 2 guide block 802.

[0060] like Figures 2 to 4 As shown, the heat preservation box 301 is internally connected to a rotating rod 901; the rotating rod 901 is fixedly connected to a plurality of spiral blades 902; and the plurality of spiral blades 902 are fixedly connected to an activated carbon plate 903;

[0061] When cold water and hot water are injected into the thermal insulation box 301 at the same time, hot water is injected from the No. 4 one-way valve 602, and cold water is injected from the water supply pipe 702. The cold and hot water are injected into the thermal insulation box 301 at the same time to flush the multiple spiral blades 902, so that the multiple spiral blades 902 rotate in coordination with the rotating rod 901. The multiple spiral blades 902 stir the hot water stored in the thermal insulation box 301 to improve the mixing effect of the cold and hot water. The activated carbon plate 903 absorbs microorganisms produced in the water due to long-term storage during the stirring process, thereby improving the comfort of water use during shower breaks.

[0062] A second water temperature sensor 904 is fixedly connected inside the insulated box 301; a solenoid valve 905 is fixedly connected to the outer wall of the bottom of the insulated box 301, and the solenoid valve 905 is electrically connected to the second water temperature sensor 904; a second return pipe 906 is fixedly connected between the solenoid valve 905 and the water inlet pipe 101, and the second return pipe 906 is located inside the diversion box 105;

[0063] When the hot water stored in the insulated box 301 turns into cold water after being left for a long time, the No. 2 water temperature sensor 904 monitors in real time that the water in the insulated box 301 changes from hot water to cold water, and the No. 2 water temperature sensor 904 sends a signal to the main controller, and the main controller sends a signal to the solenoid valve 905 to open, and the water stored in the insulated box 301 is sent into the No. 2 return pipe 906 through the flow solenoid valve 905, and then flows back to the water inlet pipe 101 through the No. 2 return pipe 906. After the reflux is completed, the solenoid valve 905 is closed, and the No. 2 hot water pipe 601 replenishes hot water to the insulated box 301 in time, which plays a role in the reflux circulation of the cooled water in the insulated box 301.

[0064] Working process: first, cold water is pumped into the water pump No. 1 102 in coordination with the water inlet pipe 101, and the cold water is sent to the semi-volumetric heat exchanger 103 for heat exchange. The semi-volumetric heat exchanger 103 is provided with heat source by the heat source and the water tank heat exchange circulation system. The heat source heats the cold water sent into the semi-volumetric heat exchanger 103. At this time, the electric slider drives the diverter block 108, which was originally connected to the No. 1 one-way valve 106 with the bellows 112, to slide close to the No. 1 water temperature sensor 111. The diverter block 108 slides and squeezes the bellows 112 to contract. The flow control component closes the channel flowing to the No. 1 one-way valve 106, and the bottom channel of the diverter block 108 is connected to the No. 2 one-way valve 11 0, the hot water generated by the cold water heat exchange is pumped into the No. 1 hot water pipe 104 by the No. 1 water pump. Due to the cold water previously retained in the No. 1 hot water pipe 104, the hot water mixes and pushes the retained cold water to be transported to the diverter block 108. The retained cold water passes through the No. 1 water temperature sensor 111 and enters the diverter block 108. The cold water falls into the No. 1 return pipe 109 through the bottom channel of the diverter block 108. The retained cold water flows back to the water inlet pipe 101 for circulation and heating, thereby reducing the waste of water resources. At the same time, the No. 1 water temperature sensor 111 monitors that the hot water transported in the No. 1 hot water pipe 104 has reached the set shower temperature. After that, the electric slider drives the diverter block 108 to slide close to the No. 1 one-way valve 106. After the bottom channel of the diverter block 108 is misaligned with the top channel of the No. 2 one-way valve 110, the bottom channel of the diverter block 108 is blocked by the inner wall of the diverter box 105. As the diverter block 108 slides close to the flow control component, the flow control component opens one side channel of the No. 1 one-way valve 106, and the bellows 112 is pulled and extended by the diverter block 108. Hot water enters the No. 1 water temperature sensor 111, the bellows 112, the diverter block 108, the flow control component and the No. 1 one-way valve 106 from the No. 1 hot water pipe 104, and finally reaches the outlet pipe 107 for discharge for showering. It plays a role in heating the shower system; when the cold water in the diverter block 108 is controlled to flow back, the diverter block 108 slides with the electric slider to fit the No. 1 water temperature sensor 111, and the rotating shaft 204 drives the blocking plate 205 to rotate to cooperate with the matching block 206 to block the side channel of the diverter block 108 close to the fixed plate 201. The cold water is pumped from the No. 1 hot water pipe 104 into the No. 1 water temperature sensor 111 and reaches the diverter block 108, and flows into the No. 2 check valve 110 and the No. 1 return pipe 109 through the bottom channel of the diverter block 108. The cold water is finally sent back to the water inlet pipe 101 for circulation, which plays a role in recycling the cold water and reducing the waste of water resources.

[0065] When controlling the hot water shower in the diverter block 108, the No. 1 water temperature sensor 111 detects that the hot water that meets the set temperature is being transported at this time, and the electric slider drives the diverter block 108 to slide close to the fixed plate 201, the bellows 112 is pulled and stretched, and the protruding front end of the push plate 202 pushes the blocking plate 205, and the blocking plate 205 rotates with the rotating shaft 204. The bottom end channel of the diverter block 108 is blocked by the inner wall of the diverter box 105. When the diverter block 108 fits the outer wall of the fixed plate 201, the rubber block 203 elastically passes over the rotating shaft 204 and pushes the blocking plate 205 against the inner wall of the diverter block 108. The hot water transported in the No. 1 hot water pipe 104 is sent to the outlet pipe 107 for showering through the No. 1 water temperature sensor 111, the bellows 112, the diverter block 108, the fixed plate 201 and the No. 1 one-way valve 106, which plays a role in heating the shower system;

[0066] When taking a shower, the cold water in the No. 1 hot water pipe 104 is backflowed and there is a water flow gap. Hot water can be poured into the insulation box 301 in advance for storage. When the cold water in the No. 1 hot water pipe 104 flows back, hot water is continuously delivered to the insulation box 301. The hot water reaches the diversion check valve 302 and is discharged into the guide pipe 303. The guide pipe 303 then directly delivers hot water to the outlet pipe 107 for showering. After the No. 1 hot water pipe 104 is connected to the outlet pipe 107, the delivery is stopped at the guide pipe 303, which plays a role in the cold water backflow in the No. 1 hot water pipe 104. When the heat source is provided in the semi-volumetric heat exchanger 103 for heat exchange, the heat source is provided in the high temperature tank of the hot and cold water tank 401 by the heat source and the water tank heat exchange circulation system. The hot water is stored in the high temperature tank of the hot and cold water tank 401, and the low temperature tank stores low temperature water such as cold water and return water. The second water pump 403 pumps the hot water in the hot and cold water tank 401 through the water pipe 402, and the hot water enters the semi-volumetric heat exchanger 103 and exchanges heat with the cold water pumped in the water inlet pipe 101. The semi-volumetric heat exchanger 10 3, the cold water for heat exchange pumped into the water delivery pipe 402 is sent to the low temperature box for storage through the return pipe 404, and the hot water for heat exchange pumped into the water inlet pipe 101 is sent to the shower place for use through the No. 1 hot water pipe 104, which plays a role in heat exchange for the cold water delivered by the water inlet pipe 101; when the hot water retained in the insulation box 301 is easily cooled after being left for a long time, the hot air generated in the high temperature box of the cold and hot water tank 401 is transported to the three-way valve 502 for diversion through the air guide pipe 501, and part of the hot air is sent to the semi-volumetric heat exchanger through the No. 1 steam distribution pipe 503 At the hot water stored in 103, the semi-volumetric heat exchanger 103 is a semi-volumetric device, so the semi-volumetric heat exchanger 103 has a space for storing hot water. After the hot air is sent into the semi-volumetric heat exchanger 103, the stored hot water can be kept warm, and the remaining hot air is sent into the air cavity 506 through the No. 2 steam distribution pipe 504 and the No. 3 check valve 505. The hot air in the air cavity 506 keeps the hot water in the insulation box 301 warm or heats it up, ensuring the temperature of the water transported in the guide pipe 303 when the cold water in the No. 1 hot water pipe 104 flows back;

[0067] When the hot water stored in the insulated box 301 is used to replenish the idle period, the hot water stored in the semi-volumetric heat exchanger 103 is pumped out by the No. 1 water pump 102 through the No. 2 hot water pipe 601, and the hot water in the semi-volumetric heat exchanger 103 is sent into the insulated box 301 through the No. 4 check valve 602. The water level in the insulated box 301 rises, and the hot water originally at the liquid level below the diverter check valve 302 is injected through the No. 4 check valve 602 to raise the liquid level. The overflowing hot water is sent to the outlet pipe 107 by the guide pipe 303 for use, thereby playing the role of replenishing the hot water in the insulated box 301; when the hot water stored in the insulated box 301 is overheated, usually the human body The water temperature during showering should be gradually increased until it reaches a comfortable temperature. A small amount of cold water needs to be added to mix the hot water during the idle period to reach the temperature of warm water and improve the comfort of showering. The diverter block 108 is slidably fitted with the No. 1 water temperature sensor 111, and part of the cold water transported to be returned in the No. 1 hot water pipe 104 is diverted upward, and most of the cold water still flows back from the bottom channel of the diverter block 108. A small amount of cold water is sent from the top channel of the diverter block 108 through the No. 5 one-way valve 701 to the upper water pipe 702, and then sent to the insulation box 301 by the upper water pipe 702 to mix with hot water, so as to achieve the effect of mixing warm water with cold water in the insulation box 301;

[0068] When the cold water transported back from the No. 1 hot water pipe 104 is diverted, the cold water enters the diverter block 108, and the cold water flushes the surface of the blocking plate 205. The No. 1 guide block 801 cooperates with the No. 2 guide block 802 to divert the flushed cold water. A small amount of cold water is sent to the upper water pipe 702, and a large amount of cold water flows back to the water inlet pipe 101, which plays a role in diverting the refluxed cold water; at the same time, when the blocking plate 205 is pushed and turned by the push plate 202 to fit the inner wall of the diverter block 108, the inner wall of the diverter block 108 squeezes the No. 2 guide block 802 to slide down and be accommodated in the No. 1 guide block 801, and the No. 2 guide block 802 squeezes the elastic member to contract and bear the force, and the No. 1 guide block 801 is blocked at the top channel of the diverter block 108, which plays a role in accommodating the No. 2 guide block 802;

[0069] When cold water and hot water are injected into the heat preservation box 301 at the same time, hot water is injected from the No. 4 check valve 602, and cold water is injected from the water supply pipe 702. The cold and hot water are injected into the heat preservation box 301 at the same time to flush the multiple spiral blades 902, so that the multiple spiral blades 902 rotate in coordination with the rotating rod 901. The multiple spiral blades 902 stir the hot water stored in the heat preservation box 301 to improve the mixing effect of the cold and hot water. The activated carbon plate 903 absorbs microorganisms generated in the water due to long-term storage during the stirring process, thereby improving the comfort of water use during the shower break;

[0070] When the hot water stored in the insulated box 301 turns into cold water after being left for a long time, the No. 2 water temperature sensor 904 monitors in real time that the water in the insulated box 301 changes from hot water to cold water, and the No. 2 water temperature sensor 904 sends a signal to the main controller, and the main controller sends a signal to the solenoid valve 905 to open, and the water stored in the insulated box 301 is sent into the No. 2 return pipe 906 through the flow solenoid valve 905, and then flows back to the water inlet pipe 101 through the No. 2 return pipe 906. After the reflux is completed, the solenoid valve 905 is closed, and the No. 2 hot water pipe 601 replenishes hot water to the insulated box 301 in time, which plays a role in the reflux circulation of the cooled water in the insulated box 301.
