Detailed Description
The present invention will be further explained with reference to the drawings attached to the specification.
As shown in fig. 2-7, the instant water heater includes an energy-saving recycling device 100 and a water instant heating device 200 shown in fig. 1. The 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, a large amount of heat energy is wasted, and the water heater can recycle part of heat lost by 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 pipe 101, a wastewater inlet 102 for introducing wastewater to be sprayed on the coil pipe 101, and a wastewater outlet 103 for discharging the wastewater, wherein a water diversion disc 104 is arranged above the coil pipe, the water diversion disc 104 is connected with the wastewater inlet 102, and water diversion grooves 105 are distributed on the periphery of the water diversion disc 104 to spray the wastewater in the water diversion disc on the coil pipe. One end of the coil is provided with a cold water inlet 106, and the other end of the coil is connected with a water inlet 202 of a hot water supply waterway 201.
The water heating device 200 includes a hot water supply circuit 201, and the hot water supply circuit 201 includes a water inlet 202, a water outlet 203, a water heater 204 connected between the water inlet and the water outlet, and a water tank 205. The water tank is shown upstream of the water heater for storing and supplying the stored water to the heater. A return water path 206 is connected between the water inlet end and the water outlet end, the return water path 206 and the hot water supply water path 201 form a circulation water path, and a circulation pump 207 is arranged in the circulation water path. In particular, the circulation pump 207 is connected in the return water path, not in the hot water supply path, and the resistance of the water flow in the hot water supply path can be reduced when the circulation pump is not operated. The water inlet end 202 has a first check valve 208 for connecting with an upstream waterway (energy saving recovery device) and a second check valve 209 for connecting with a return waterway, wherein the first check valve and the second check valve cooperate to make the water flow of the upstream waterway flow to the hot water supply waterway and make the water flow of the return waterway flow to the hot water supply waterway.
In structural configuration, water tank 205 is surrounded by coil pipe 101, can utilize the waste water that drenches down when the coil pipe heat exchange to keep warm to the water tank, avoids the temperature of water in the water tank to reduce fast. The water heater 204 is located outside and near the coil so that heat dissipated by the water heater can be transferred to the coil for partial recovery of the dissipated heat. The outlet end 203 of the hot water supply circuit has a hot water outlet 210. The water heater comprises a shell 400, and a waste water inlet 102, a waste water outlet 103, a cold water inlet 106 and a hot water outlet 210 extend out of the shell 400 so as to be connected with pipelines. In order to facilitate assembly and maintenance of the internal structure, the housing can be designed into an assembly structure, such as a top cover, a bottom plate and side plates which can be independently disassembled. The waste water inlet 102 is used for flowing used waste water, such as sewage of the connecting counter basin 600, the waste water outlet 103 is connected with a waste water drainage pipeline, the cold water inlet 106 is connected with a tap water interface, and the hot water outlet 210 is connected with the shower head 500.
In order to achieve compact structure and convenient assembly, the water inlet end 202 is made into a water inlet end tee joint (see fig. 10), the water outlet end 203 is made into a water outlet end tee joint (see fig. 5 and 7), an integrated valve 300 (see fig. 9) is further configured, a first interface 301, a second interface 302, a third interface 303 and a fourth interface 304 are arranged on the integrated valve, the first interface is connected with an outlet of the water tank, the second interface is connected with an inlet of the water heater, the third interface is connected with the water outlet end tee joint, the fourth interface is connected with an inlet of the circulating pump, connection of a hot water supply waterway and a return waterway is achieved, and arrows in the drawing show water flow directions. The water inlet end tee joint and the integrated valve are assembled at the bottom of the water tank (see figure 8).
In view of the above structure, when the water outlet end outputs hot water outwards, the water inlet end enters water, and the water flow in the hot water supply waterway flows; when the water outlet end does not output hot water outwards, the water inlet end does not feed water, the circulating pump works, and the water flow in the circulating waterway circulates according to the flow direction of the water outlet end, the backflow waterway, the water inlet end, the hot water supply waterway and the water outlet end.
Specifically, when water is used, the shower head 500 is opened, the water outlet end outputs hot water outwards, at the moment, tap water supplies water, the hot water flowing out of the shower head flows to the water distribution disc 104 through the waste water inlet and is sprayed to the coil pipe 101 after being used, partial heat is transferred to cold water flowing through the coil pipe, the cold water flowing through the coil pipe is heated to be preheated water, and heat recovery is achieved. The preheated water enters the water tank 205, is heated to a desired water temperature in the water heater 204, and then flows out of the water outlet end 203 and the shower head 500 for use. Meanwhile, the circulation pump 207 is not operated, and no water flows in the circulation water path. 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.
When the water is not used, the shower head 500 is closed, the water outlet end 203 does not output hot water outwards, tap water does not flow into the water heater, no water flows in a water path between the cold water inlet and the water inlet end, the water inlet end does not feed water, the circulating pump 207 works, and the water flow in the circulating water path circulates according to the flow directions of the water outlet end 203, the backflow water path 206, the water inlet end 202, the hot water supply water path 201 and the water outlet end 203. Therefore, the water heater is delayed and stopped to heat water to cause local water temperature rise, hot water of the water temperature rise part is dispersed into the whole circulation water channel through circulation of the circulation water channel, and the scaling phenomenon caused by overhigh water temperature and overhigh local water temperature when water is reused is avoided.
Furthermore, when the water outlet end outputs hot water outwards, the water temperature of the water inlet of the water heater (the water temperature of the preheated water), the water temperature of the water outlet of the water heater and the flow rate of the hot water output outwards by the water outlet end are detected, and the power of the water heater is controlled according to the detected values so as to control the water temperature of the hot water output outwards by the water outlet end to be the expected water temperature. The water temperature may be controlled by calculating the power required to heat the temperature of the preheated water to the desired temperature from the temperature difference and flow rate between the temperature of the outlet water of the water heater and the temperature of the preheated water, and by applying the power to the water heater, the power may be corrected empirically. The desired water temperature may be a specific temperature value or a temperature range. When the water outlet end outputs hot water outwards, if the temperature of the water outlet of the water heater is lower than the expected water temperature (the expected water temperature can be a certain temperature value selected in the temperature range when the expected water temperature is in the temperature range), the water heater is enabled to work to heat the water. The detection of the water temperature is realized by installing a temperature sensor at a corresponding position.
When the water outlet end does not output hot water outwards, the water heater is controlled to heat the water flowing through when the temperature of the inlet water of the water heater is detected and is lower than a desired water temperature (the desired water temperature can be a certain temperature value selected in the temperature range when the desired water temperature is in the temperature range), and the water heater is controlled to stop heating the water flowing through when the temperature of the inlet water reaches or is higher than the desired water temperature (the desired water temperature can be a certain temperature value selected in the temperature range when the desired water temperature is in the temperature range). Therefore, the preheating water can be heated to the expected water temperature which can be directly used, and the hot water with the expected water temperature can be output when the shower head is started. If the water temperature of the preheated water is lower than the expected water temperature, the water heater can rapidly heat the preheated water to the expected water temperature, and the second heat function is realized. Since such an operating state is immediately started when the water supply is stopped, and the water heater requires time for cooling, the temperature of the outlet water of the water heater is maintained at a high temperature, which cannot accurately represent the temperature of the water in the circulation water path. The temperature of water in the circulating water path (especially the water tank) can be represented accurately by detecting the temperature of water entering the water heater, so that the work of the water heater is controlled.
The automatic control of the water heater can be realized through the circuit board 700.
