The invention provides a heating water heating device, and particularly relates to a heating water heater.
Referring to fig. 1, a heating water heater 100 according to the present invention includes a heating water inlet 101, a heating water outlet 102, a domestic water inlet 103, and a domestic water outlet 104. The heating water heating device 100 comprises a first heat exchanger 120, a second heat exchanger 130 and a flow dividing control device 140, wherein the first heat exchanger 120 is communicated with the heating water inlet 101 and the heating water outlet 102; the second heat exchanger 130 has a first flow channel 131 and a second flow channel 132, an inlet of the first flow channel 131 is communicated with an outlet of the first heat exchanger 120, an outlet of the first flow channel 131 is respectively communicated with the heating water outlet 102 and an inlet of the first heat exchanger 120, and the second flow channel 132 is communicated with the domestic water inlet 103 and the domestic water outlet 104. The flow dividing control means 140 serves to distribute the amount of water flowing out of the first flow passage 131 to the heating water outlet 102 and to the first heat exchanger 120.
In the embodiment of the present invention, the heating water inlet 101 and the heating water outlet 102 are configured to communicate with a heating water pipeline 200, and the heating water pipeline 200, the first flow channel 131 and the first heat exchanger 120 form a heating water circulation flow channel. The water heated by the first heat exchanger 120 flows into the first flow channel 131 of the second heat exchanger 130, and further flows into the heating water pipeline 200 through the heating water outlet 102, and then flows back into the first heat exchanger 120 from the heating water inlet 101. Here, the heating water line 200 is provided with a heating device 210, such as a radiator, etc. The domestic water inlet 103 and the domestic water outlet 104 are used for communicating with a domestic water pipeline 300, and the domestic water pipeline 300 and the second flow passage 132 form a domestic water circulation flow passage. In this way, the heating water in the first flow channel 131 heats the cold water flowing into the second flow channel 132, and the heated water flows into the domestic water pipe 300 from the domestic water outlet 104, thereby providing domestic hot water to the user. Therefore, the heating and water heating apparatus 100 of the present invention can provide domestic hot water as well as heating. In addition, the life water line 300 is communicated with a water source 310, and water can be supplemented from the water source 310 when the water in the life water line 300 is used.
It should be noted that in summer, when a user uses domestic hot water, the cold water entering the second flow channel 132 of the second heat exchanger 130 is heated to a temperature required by the user by the heating water in the first flow channel 131, and then the water flowing out of the first flow channel 131 is controlled by the diversion control device 140 to flow to the heating water outlet 102, further to the heating device 210, and then flows back to the first heat exchanger 120 from the heating device 210. Since the heating water in the first flow passage 131 is cooled by the cold water in the second flow passage 132, and the temperature of the cooled heating water is lower than the room temperature, the heating water lower than the room temperature flows to the heating device 210, then flows back to the heating water inlet 101 and further flows back to the first heat exchanger 120, in this process, the heating water lower than the room temperature absorbs the heat in the indoor air, thereby achieving the effect of lowering the room temperature and realizing the refrigeration function of the heating and water heating device 100.
In the embodiment of the present invention, the diversion control means 140 serves to distribute the amount of water flowing out of the first flow channel 131 to the heating water outlet 102 and to the first heat exchanger 120. For example, referring to fig. 1, in an embodiment, the diversion control device 140 includes a first inlet port 141, a first outlet port 144, and a second outlet port 145, wherein the first inlet port 141 communicates with the outlet of the first flow channel 131, the first outlet port 144 communicates with the heating water outlet 102, and the second outlet port 145 communicates with the inlet of the first heat exchanger 120. When a user only needs the heating water heating apparatus 100 to provide heating, the bypass control device 140 opens the first outlet port 144 and closes the second outlet port 145, so that the water flowing out of the first flow channel 131 flows to the heating water outlet 102 and further to the heating apparatus 210, thereby providing heating to the user. When a user needs a large amount of domestic hot water provided by the heating and hot water apparatus 100 or is in a bathroom mode, the diversion control device 140 closes the first outlet port 144 and opens the second outlet port 145 to prevent water flowing out of the first flow channel 131 from flowing to the heating water outlet 102, so that water in the first flow channel 131 is mainly used for heating the domestic water in the second flow channel 132 to provide more domestic hot water for the user.
In another embodiment, referring to fig. 2, the flow dividing control device 140 includes a second inlet end 142, a third inlet end 143 and a third outlet end 146, the second inlet end 142 is connected to the outlet of the first flow channel 131, the third inlet end 143 is connected to the heating water inlet 101, and the third outlet end 146 is connected to the inlet of the first heat exchanger 120. When the user only needs the heating hot water apparatus 100 to provide heating, the bypass control device 140 opens the third inlet port 143 and closes the second inlet port 142, so that the water flowing out of the first flow passage 131 flows to the heating water outlet 102, thereby providing heating to the user. When a user needs a large amount of domestic hot water provided by the heating and hot water apparatus 100 or is in a bathroom mode, the diversion control device 140 closes the third inlet 143 and opens the second inlet 142 to prevent the heating water in the heating apparatus 210 from flowing back from the heating water inlet 101 to the first heat exchanger 120, so as to prevent the water flowing out of the first flow channel 131 from flowing to the heating water outlet 102, so that the water in the first flow channel 131 is mainly used for heating the domestic water in the second flow channel 132 to provide more domestic hot water for the user.
Specifically, the flow dividing control device 140 may be a three-way valve, and of course, the flow dividing control device 140 may also be a valve having at least three ports. Since the total amount of the water flowing out of the first flow passage 131 of the second heat exchanger 130 is constant, by providing the diversion control means 140, the amount of the water distributed to flow out of the first flow passage 131 of the second heat exchanger 130 into the first heat exchanger 120 can be controlled, thereby achieving the purpose of distributing the amount of the water flowing out of the first flow passage 131 to flow to the heating water outlet 102 and to flow into the first heat exchanger 120.
The heating hot water device 100 provided by the technical scheme of the invention comprises a first heat exchanger 120, a second heat exchanger 130 and a flow dividing control device 140, wherein the first heat exchanger 120 is communicated with a heating water inlet 101 and a heating water outlet 102; the second heat exchanger 130 has a first flow channel 131 and a second flow channel 132, an inlet of the first flow channel 131 is communicated with an outlet of the first heat exchanger 120, an outlet of the first flow channel 131 is respectively communicated with the heating water outlet 102 and an inlet of the first heat exchanger 120, and the second flow channel 132 is communicated with the domestic water inlet 103 and the domestic water outlet 104. The diverting control means 140 serves to distribute the amount of water flowing out of the first flow passage 131 toward the heating water outlet 102 and into the first heat exchanger 120. The water flowing into the first flow passage 131 can heat the water in the second flow passage 132 on the one hand, and the water in the first flow passage 131 flows to the heating water outlet 102 on the other hand, so as to provide heating for the heating device 210 (for example, a radiator). In addition, in summer, when a user uses hot domestic water, after cold water (lower than room temperature) entering the second flow passage 132 is heated to a temperature required by the user by the heating water in the first flow passage 131, the flow of water flowing out of the first flow passage 131 is controlled to flow to the heating water outlet 102 through the diversion control device 140, and further to the heating apparatus 210; because the heating water in the first flow passage 131 is cooled by the cold water in the second flow passage 132, and the temperature of the cooled heating water is lower than the room temperature, the heating water lower than the room temperature flows to the heating device 210, then flows back to the heating water inlet 101 and further flows back to the first heat exchanger 120, in the process, the heating water lower than the room temperature absorbs the heat in the indoor air, thereby achieving the effect of lowering the room temperature and realizing the function of cooling in summer.
Referring to fig. 1, the heating and water heating apparatus 100 further includes a first water pump 150, and the first water pump 150 is communicated with the first heat exchanger 120, and is used for driving water flowing out of the first flow channel 131 to flow into the first heat exchanger 120, and driving water flowing in from the heating water inlet 101 to flow into the first heat exchanger 120.
The heating and water heating apparatus 100 further includes a second water pump 160, and the second water pump 160 is communicated with the second flow passage 132 to drive water in the second flow passage 132 to flow. Wherein the outlet of the second water pump 160 is communicated with the second flow passage 132, and the inlet of the second water pump 160 and the domestic water outlet 104 are used for communicating with the domestic water pipeline 300.
It can be understood that if the user does not use the domestic hot water for a long time, the temperature of the hot water in the domestic water pipe is lowered and remains in the domestic water pipe 300; when the user uses the domestic hot water again, the second water pump 160 is first turned on, the cold water remained in the domestic water pipeline 300 is driven by the second water pump 160 to flow into the second flow passage 132, and is heated into hot water, and the hot water flows back into the domestic water pipeline 300 from the domestic water outlet 104 for the user to use. So, the user can directly use hot water, and need not earlier remain the cold water evacuation in the life water pipeline 300 originally to avoid latency, improved user's experience comfort level.
There are various ways in which the inlet of the second water pump 160 and the domestic water outlet 104 are used to communicate with the domestic water pipeline 300, as follows:
in one mode, the inlet of the second water pump 160 is communicated with the domestic water inlet 103, and the domestic water inlet 103 and the domestic water outlet 104 are used for communicating with the domestic water pipeline 300. Specifically, the domestic water circuit 300 includes a first circulation circuit 300a, and the domestic water inlet 103 and the domestic water outlet 104 are adapted to communicate with the first circulation circuit 300 a.
In a second mode, the heating and water heating apparatus 100 further includes a water return port 105, an inlet of the second water pump 160 is communicated with the water return port 105, and the water return port 105 and the domestic water outlet 104 are used for communicating with the domestic water circuit 300. Specifically, the domestic water pipeline 300 includes a second circulation pipeline 300b, and the water return port 105 and the domestic water outlet 104 are configured to communicate with the first circulation pipeline 300 a.
In the embodiment of the present invention, the heating hot water apparatus 100 further includes a heating unit for heating the first heat exchanger 120. The heating unit can be different heating modes, for example, the heating unit can be a burner which is used for heating water flowing through the heat exchanger by burning gas; the heating unit can also be an electric heating device, such as a resistance wire, an electric heating rod and the like, and heats water flowing through the heat exchanger in an electric heating mode; the heating unit may also be a condenser through which water flowing through the heat exchanger is heated. Of course, the kind of the heating unit is not limited thereto.
Considering that the heat source of the second heat exchanger 130 is the hot water heated by the first heat exchanger 120, in order to prevent the heat energy of the hot water flowing into the second heat exchanger 130 (the first flow channel 131) from dissipating and improve the heat energy utilization rate of the hot water flowing into the second heat exchanger 130 (the first flow channel 131), an insulating layer 400 may be disposed outside the second heat exchanger 130 to achieve the effects of heat insulation and heat preservation.

In this way, when the heating and water heating apparatus 100 needs to provide domestic hot water, the control unit of the heating and water heating apparatus 100 may call the corresponding relationship according to the inlet water temperature of the domestic water detected by the first temperature sensor, the water flow rate of the domestic water detected by the first flow sensor, and the outlet water temperature of the domestic water set by the user, calculate the heat load required to heat the inlet water temperature of the domestic water detected by the first temperature detection device to the outlet water temperature of the domestic water set by the user, and then control the diversion control device 140 to distribute the amount of water flowing out of the first flow channel 131 to the heating water outlet 102 and the amount of water flowing into the first heat exchanger 120; thereby preventing the domestic water from flowing out of the domestic water outlet 104The temperature of water is too high, avoids scalding the user, has improved user's use comfort.
