Description

Technical Field

[0001] The invention relates to the technical field of wall-mounted boilers, and in particular to a wall-mounted boiler. Background Art

[0002] At present, most of the gas heating water boilers in the industry use the main heat exchanger to exchange heat for heating water. When using domestic hot water, the heat of the small heating cycle is exchanged with domestic water in the plate heat exchanger. That is, when the user uses domestic hot water, the heating function cannot be used. Only when the domestic water is stopped can the heating function continue to be used. However, the room temperature may have dropped at this time and cannot meet the user's heating needs when the temperature is low in winter. Summary of the invention

[0003] The main purpose of the present invention is to provide a wall-mounted boiler to solve the problem in the prior art that the wall-mounted boiler cannot meet the needs of heating and domestic water at the same time.

[0004] To achieve the above object, the present invention provides a wall-mounted boiler, comprising a heater, a heating water inlet pipeline, a heating water outlet pipeline, a domestic water inlet pipeline and a domestic water outlet pipeline, characterized in that the wall-mounted boiler also includes:

[0005] A first heat exchanger is arranged in the first heat exchange channel of the wall-mounted boiler and is connected to the heating water inlet pipeline and the heating water outlet pipeline respectively;

[0006] A second heat exchanger is disposed in the second heat exchange channel of the wall-mounted boiler and is connected to the domestic water inlet pipeline and the domestic water outlet pipeline respectively; and

[0007] The heat exchange channel baffle is movably arranged between the first heat exchange channel, the second heat exchange channel and the heater, and is switched back and forth between the first heat exchange channel position and the second heat exchange channel position, and can form a barrier between the first heat exchange channel and the heater at the first heat exchange channel position, and form a barrier between the second heat exchange channel and the heater at the second heat exchange channel position; before the first heat exchange channel position and the second heat exchange channel position, both the first heat exchange channel and the second heat exchange channel are connected to the heater.

[0008] Furthermore, the wall-mounted boiler includes a main heat exchange channel connected to the heater, and the first heat exchange channel and the second heat exchange channel are separated and formed by a channel partition plate arranged in the main heat exchange channel.

[0009] Furthermore, the heat exchange channel baffle and the channel partition are sealed.

[0010] Furthermore, the wall-mounted boiler also includes a guide rail structure arranged on the wall-mounted boiler body, and the heat exchange channel baffle is slidably mounted on the guide rail structure.

[0011] Furthermore, the wall-mounted boiler also includes a driving device for driving the heat exchange channel baffle to move, and the driving device is transmission-connected to the heat exchange channel baffle. Under the drive of the driving device, the heat exchange channel baffle switches back and forth between the first heat exchange channel position and the second heat exchange channel position.

[0012] Furthermore, the driving device is a driving motor installed on the wall-mounted boiler.

[0013] Furthermore, the driving device is a telescopic cylinder installed on the wall-mounted boiler.

[0014] Furthermore, the heater is a burner.

[0015] Furthermore, the first heat exchanger and the second heat exchanger are both fin-type heat exchangers.

[0016] Furthermore, the wall-mounted boiler is a gas-fired wall-mounted boiler.

[0017] The technical solution of the present invention has the following advantages:

[0018] 1. In the wall-mounted boiler provided by the present invention, the wall-mounted boiler can realize independent heating, independent bathroom and simultaneous heating of the bathroom by switching the position of the baffle of the heat exchange channel. At the same time, while realizing the heating and bathroom functions at the same time, the use of the bathroom function will not affect the realization of the heating function, thereby improving the user experience.

[0019] 2. In the wall-mounted boiler provided by the present invention, the wall-mounted boiler includes a total heat exchange channel connected to the heater, and the first heat exchange channel and the second heat exchange channel are formed by a channel partition arranged in the total heat exchange channel, so that the structure of the entire wall-mounted boiler is more compact, and at the same time, the first heat exchange channel and the second heat exchange channel do not affect each other.

[0020] 3. In the wall-mounted boiler provided by the present invention, a seal is arranged between the heat exchange channel baffle and the channel partition, so that when the wall-mounted boiler is used for heating or bathroom alone, the first heat exchange channel and the second heat exchange channel do not affect each other, the sealing between the two is better, and the reliability of the wall-mounted boiler is better.

[0027] like Figure 1As shown, the wall-mounted boiler in this embodiment is specifically a gas wall-mounted boiler, including a heater 10, a heating water inlet pipeline 21, a heating water outlet pipeline 23, a domestic water inlet pipeline 31 and a domestic water outlet pipeline 33. The wall-mounted boiler also includes: a first heat exchanger 25, which is arranged in a first heat exchange channel 27 of the wall-mounted boiler, and is respectively connected to the heating water inlet pipeline 21 and the heating water outlet pipeline 23, heats the water passing through the heating water inlet pipeline 21 and outputs hot water through the heating water outlet pipeline 23, and a second heat exchanger 35 is arranged in a second heat exchange channel 37 of the wall-mounted boiler, and is respectively connected to the domestic water inlet pipeline 31 and the domestic water outlet pipeline 33, The water inlet through the domestic water inlet pipe is heated and the hot water is output through the domestic water outlet pipe; and the heat exchange channel baffle 40 can be movably arranged between the first heat exchange channel 27 and the second heat exchange channel 37 and the heater 10, and can be switched back and forth between the first heat exchange channel position and the second heat exchange channel position, and can form a barrier between the first heat exchange channel 27 and the heater 10 at the first heat exchange channel position, and form a barrier between the second heat exchange channel 37 and the heater 10 at the second heat exchange channel position. Before the first heat exchange channel position and the second heat exchange channel position, both the first heat exchange channel 27 and the second heat exchange channel 37 are connected to the heater 10. Then, by using the wall-mounted boiler in this embodiment, the wall-mounted boiler can realize independent heating, independent bathroom and simultaneous heating of bathroom by switching the position of the heat exchange channel baffle 40. At the same time, while realizing the heating and bathroom functions at the same time, the use of the bathroom function will not affect the realization of the heating function, thereby improving the user experience.

[0028] Specifically, the wall-mounted boiler in this embodiment includes a total heat exchange channel connected to the heater 10, and the first heat exchange channel 27 and the second heat exchange channel 37 are separated and formed by a channel partition 50 arranged in the total heat exchange channel, so that the structure of the entire wall-mounted boiler is more compact. At the same time, the first heat exchange channel 27 and the second heat exchange channel 37 do not affect each other, that is, the heating function and the bathroom function of the wall-mounted boiler do not interfere with each other.

[0029] Preferably, the heat exchange channel baffle 40 and the channel partition 50 in this embodiment are sealed, so that when the wall-mounted boiler is used for heating or bathroom alone, the first heat exchange channel 27 and the second heat exchange channel 37 do not affect each other, the sealing between the two is better, and the reliability of the wall-mounted boiler is better.

[0030] Specifically, the wall-mounted boiler in this embodiment further includes a guide rail structure arranged on the wall-mounted boiler body, and the heat exchange channel baffle 40 is slidably mounted on the guide rail structure, so that the heat exchange channel baffle 40 can be conveniently switched back and forth between the first heat exchange channel position and the second heat exchange channel position, and the wall-mounted boiler further includes a driving device 60 for driving the heat exchange channel baffle 40 to move, and the driving device 60 is transmission-connected to the heat exchange channel baffle 40, and under the drive of the driving device 60, the heat exchange channel baffle 40 switches back and forth between the first heat exchange channel position and the second heat exchange channel position. Specifically, the driving device 60 in this embodiment is a driving motor installed on the wall-mounted boiler.

[0031] In a variant embodiment of the present embodiment, the driving device 60 is a telescopic cylinder installed on the wall-mounted boiler, which can also realize the switching back and forth of the heat exchange channel baffle 40 between the first heat exchange channel position and the second heat exchange channel position.

[0032] Specifically, the heater 10 in this embodiment is a burner. Of course, the heater 10 is not limited to a burner, and may also be an electric heater 10 or the like.

[0033] Preferably, the first heat exchanger 25 and the second heat exchanger 35 in this embodiment are both finned heat exchangers, and the high-temperature flue gas generated by the burner passes through the finned heat exchanger to heat the water therein.

[0034] Combine the following Figure 1 The working state of the wall-mounted boiler in this embodiment is described.

[0035] In heating mode: the whole machine is turned on by default and runs in heating mode. At this time, the driving motor drives the heat exchange channel baffle 40 to move to the second heat exchange channel position, and the high-temperature flue gas can only enter from the first heat exchange channel position to fully exchange heat with the heating heat exchanger. At this time, since the second heat exchange channel position is blocked by the flue baffle, the flue gas cannot enter the second heat exchange channel 37 and cannot exchange heat with the water in the second heat exchanger 35, so the whole machine only reflects the heating function.

[0036] Separate bathroom mode: When the user does not need to use the heating function in summer and only needs the bathroom function, when the water flow sensor detects that the water flow reaches a certain value, the bathroom function is started. At this time, the drive motor drives the heat exchange channel baffle 40 to move to the first heat exchange channel position, and the high-temperature flue gas can only enter from the second heat exchange channel position and fully exchange heat with the second heat exchanger 35. At this time, since the first heat exchange channel position is blocked by the baffle, the flue gas cannot enter the first heat exchange channel 27 and cannot exchange heat with the water in the heating heat exchanger, so the whole machine only reflects the bathroom function.

[0037] Heating and bathroom use at the same time: When the water flow sensor detects that the water flow reaches a certain value, the bathroom function is started. At this time, the drive motor drives the heat exchange channel baffle 40 to move to the position between the first heat exchange channel 27 and the second heat exchange channel 37, and the high-temperature flue gas can enter from both sides of the first heat exchange channel position and the second heat exchange channel position area. That is, the high-temperature flue gas enters the heating and bathroom heat exchange areas at the same time, and participates in heating and bathroom heat exchange at the same time, so that the heating function does not stop when using domestic hot water.

[0038] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
