Technical Field

[0001] The utility model belongs to the technical field of household appliances and relates to a wall-mounted electric boiler, in particular to a wall-mounted heating and bathing integrated electric boiler. Background Art

[0002] The main function of an electric boiler is to provide heating for family life. It is a heating device that can be connected to radiators, floor heating, ground source heat pumps and other heating equipment to provide heating for the family and meet family needs. In addition to heating, it can also be used as a water heater to provide hot water, which is very convenient and comfortable. Whether the user is washing vegetables, hands, or washing their hair and taking a bath, they can use hot water at any time.

[0003] At present, electric boilers for heating and bathing are mostly used to supply domestic hot water in summer and heating and domestic hot water in winter. Therefore, the electric boilers in the prior art use a three-way valve as a flow switching component to exchange the heated heating water with domestic water through a plate heat exchanger to meet the users' domestic water needs. Although such a structure can basically meet the needs of users, a small number of user groups have the need to use domestic hot water and heating for a long time at the same time in winter. At this time, since the temperature of the heating water decreases after heat exchange with the domestic water, long-term use will seriously affect the heating effect and experience.

BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] like Figure 1 As shown, the utility model provides a wall-mounted integrated heating and bathing electric boiler, comprising a heating water tank 2, a heat exchanger 3, a heating water inlet pipe 4, a heating water outlet pipe 5, a bathing water inlet pipe 6, and a bathing water outlet pipe 7 installed in a housing 1. The heating water tank 2 is divided into a first chamber 21 connected to the heating water inlet pipe 4 and a second chamber 22 connected to the heating water outlet pipe 5 by a partition. The first chamber 21 has a first electric heating element 23 to heat the heating water entering the first chamber 21. The first chamber 21 and the second chamber 22 are connected to the two ends of the heat release channel of the heat exchanger 3 through the first heat exchange tube 31 and the second heat exchange tube 32 respectively, so that the heated heating water enters the second chamber 22 through the heat release channel of the heat exchanger 3. The two ends of the heat absorption channel of the heat exchanger 3 are respectively connected to the bathing water inlet pipe 6 and the bathing water outlet pipe 7, so that the heating water in the heat release channel heats the bathing water passing through the heat absorption channel. The second chamber 22 is provided with a second electric heating element 24 to secondary heat the heating water entering the second chamber 22.

[0018] The heating water tank 2 is connected to the water inlet of the heating system through the heating water outlet pipe 5 and is connected to the water outlet of the heating system through the heating water inlet pipe 4 to form a heating water circulation loop. A circulation pump 41 is installed on the heating water inlet pipe 4. When bathing is needed while heating in winter, first, the heating water enters the first chamber 21 of the heating water tank 2 from the heating water inlet pipe 4, is heated by the first electric heating element 23, and enters the heat release channel of the heat exchanger 3 through the first heat exchange pipe 31; at this time, the bathing water simultaneously enters the heat absorption channel of the heat exchanger 3 from the bathing water inlet pipe 6, and exchanges heat with the heating water in the heat release channel. The temperature of the bathing water increases after the heat exchange, and flows out directly from the bathing water outlet pipe 7 for user use; then, the temperature of the heating water decreases after the heat exchange, and enters the second chamber 22 of the heating water tank 2 through the second heat exchange pipe 32, is heated for the second time by the second electric heating element 24, and is sent to the heating system through the heating water outlet pipe 5 for heating, so that the electric boiler can realize the function of bathing while providing the heating function, and ensure that the heating effect is not affected; finally, the heating water after heating is completed enters the heating water tank 2 from the heating water inlet pipe 4 again under the power of the circulating pump 41 for circulation.

[0019] A first connecting pipe 8 is installed between the first heat exchange pipe 31 and the heating water outlet pipe 5 . One end of the first connecting pipe 8 is connected to the first heat exchange pipe 31 through a first three-way valve 81 , and the other end is connected to the heating water outlet pipe 5 through a second three-way valve 82 . When only the separate heating function is needed in winter, the first three-way valve 81 is controlled to connect the first connecting pipe 8 and the first heat exchange pipe 31, and the second three-way valve 82 is controlled to connect the first connecting pipe 8 and the heating water outlet pipe 5. At this time, the heating water enters the first chamber 21 of the heating water tank 2 from the heating water inlet pipe 4, and after being heated by the first electric heating element 23, it directly passes through the first heat exchange pipe 31, the first three-way valve 81, the first connecting pipe 8, the second three-way valve 82 and the heating water outlet pipe 5, and is sent to the heating system for heating, thereby reducing the secondary heating process of the second electric heating element 24 in the second chamber 22 of the heating water tank 2, and reducing the energy consumption when providing the heating function alone. Finally, the heating water after heating is completed enters the heating water tank 2 again from the heating water inlet pipe 4 under the power of the circulating pump 41 for circulation.

[0020] A second connecting pipe 9 is installed between the second heat exchange pipe 32 and the heating water inlet pipe 4. One end of the second connecting pipe 9 is connected to the second heat exchange pipe 32 through a third three-way valve 91, and the other end is connected to the heating water inlet pipe 4 through a fourth three-way valve 92. When heating is not needed in summer and only the bathing function is needed, the first three-way valve 81 is controlled to connect the first heat exchange pipe 31, the third three-way valve 91 is controlled to connect the second connecting pipe 9 and the second heat exchange pipe 32, and the fourth three-way valve 92 is controlled to connect the second connecting pipe 9 and the heating water inlet pipe 4. At this time, the heating water enters the first chamber 21 of the heating water tank 2 from the heating water inlet pipe 4, is heated by the first electric heating element 23, and then enters the heat release channel of the heat exchanger 3 through the first heat exchange pipe 31; at this time, the bathing water is simultaneously discharged from the first heat exchange pipe 31 and the second heat exchange pipe 32 is discharged. The bathing water inlet pipe 6 enters the heat absorption channel of the heat exchanger 3 and exchanges heat with the heating water in the heat release channel. The temperature of the bathing water increases after the heat exchange and flows out directly from the bathing water outlet pipe 7 for user use; then, the heating water after heat exchange returns to the heating water inlet pipe 4 through the second heat exchange pipe 32, the third three-way valve 91, the second connecting pipe 9 and the fourth three-way valve 92, and enters the heating water tank 2 from the heating water inlet pipe 4 again under the power of the circulating pump 41 for recycling, thereby reducing the energy consumption when providing bathing function alone in summer.

[0021] A drain pipe 10 is also installed in the shell 1, and one end of the drain pipe 10 is connected to the heating water outlet pipe 5 through a fifth three-way valve 11. A water supply pipe 12 is also installed in the shell 1, and one end of the water supply pipe 12 is connected to the heating water inlet pipe 4 through a sixth three-way valve 13. When replacing the heating water for the electric boiler in summer, control the second three-way valve 82 to connect the heating water outlet pipe 5, control the fifth three-way valve 11 to connect the heating water outlet pipe 5 and the drain pipe 10, control the sixth three-way valve 13 to connect the heating water inlet pipe 4 and the make-up water pipe 12, and send the new heating water from the make-up water pipe 12 into the heating water tank 2 via the sixth three-way valve 13 and the heating water inlet pipe 4, and discharge the "old" heating water in the heating water tank 2 from the drain pipe 10 via the heating water outlet pipe 5 and the fifth three-way valve 11. In addition, when the electric boiler is not used for a long time in winter, the heating water in the heating water tank 2 can be completely discharged through the drain pipe 10 to prevent the water from freezing and damaging the electric boiler and the external heating system.

[0022] The heating water inlet pipe 4, the heating water outlet pipe 5, the bathing water inlet pipe 6, the bathing water outlet pipe 7, the drain pipe 10 and the water supply pipe 12 extend from the same side of the shell 1, which is convenient for the connection and installation of external pipes.

[0023] The first three-way valve 81, the second three-way valve 82, the third three-way valve 91, the fourth three-way valve 92, the fifth three-way valve 11, and the sixth three-way valve 13 are all electric three-way valves controlled by a controller, and the first electric heating element 23, the second electric heating element 24, and the circulation pump 41 are all electrically connected to the controller.

[0024] The above contents are merely examples and explanations of the structure of the utility model. The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of the utility model.
