Description

Technical Field

[0001] The utility model relates to the field of wall-mounted boilers, in particular to an air jet assembly and a wall-mounted boiler. Background Art

[0002] The wall-mounted boiler air jet pipe has segmented and non-segmented structures.

[0003] Among them, the combustion load range of the wall-mounted boiler without segmented jet pipes is narrow, and all the jet holes of the jet pipe output gas at the same time. Even if the gas flow is adjusted to the minimum, multiple combustion holes output gas at the same time to heat the heat exchanger, which will cause the minimum water outlet temperature to be too high, that is, the minimum heating power of the jet combustion is too high and cannot meet the usage requirements.

[0004] The jet pipes of some existing wall-mounted boilers are increased to two or three-segment structures. The segmented structure is generally an independent branch gas path, which is composed of a gas distribution pipe with a chamber, two gas pipes and an air inlet pipe connected to the two gas pipes respectively. There are many gas pipes, which makes the gas distribution mechanism structure complex and requires a large installation space.

[0005] Therefore, based on the above problems, it is necessary to improve the existing wall-mounted boiler to solve the above problems. Utility Model Content

[0028] The following is combined with Figure 1-4 , the specific implementation methods of the utility model are further described in detail to make the technical solution of the utility model easier to understand and grasp.

[0029] In this embodiment, it should be understood that the terms "middle", "upper", "lower", "top", "right", "end", "front", "back", "middle", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0030] In addition, in this specific embodiment, if the connection or fixing method between components is not specifically described, the connection or fixing method can be through bolt fixing or pin fixing, or pin shaft connection, etc. commonly used in the prior art, and therefore, it is not described in detail in this embodiment.

[0031] like Figure 1 As shown, a wall-mounted boiler 8 includes: a main controller 81, a burner 82, a gas inlet component 83 and an air jet component 84. The main controller 81 is connected to the air jet component 84, and the air jet component 84 is connected to the gas inlet component 83 and the burner 82.

[0032] like Figure 2-4 As shown, an air injection assembly 84 includes:

[0033] A tube body 1 and multiple nozzle members 4 are provided. Multiple chambers 2 that can communicate with each other are formed in the tube body 1, and each chamber 2 is provided with a corresponding connecting channel 3 connected thereto. The nozzle member 4 is connected to the tube body 1 and is respectively connected to each chamber 2. The nozzle member 4 is used to eject gas. In this embodiment, the chamber 2 includes a first chamber 21, a second chamber 22, and a third chamber 23. The connecting channel 3 includes a first connecting channel 31, a second connecting channel 32, and a third connecting channel 33 that are respectively connected to the first chamber 21, the second chamber 22, and the third chamber 23. The first chamber 21 is formed with a first gas distribution channel 211 and a second gas distribution channel 212. The first chamber 21 is connected to the second connecting channel 32 and the third connecting channel 33 through the first gas distribution channel 211 and the second gas distribution channel 212, so as to be respectively connected to the second chamber 22 and the third chamber 23.

[0034] Specifically, there is a first sealing member 5 in the tube body 1 to form a first chamber 21 and a third chamber 23. A second sealing member 213 is detachably provided in the first chamber 21 to separate and form a second chamber 22. The first sealing member 5 is a sealing wall and the second sealing member 213 is a blocking cover. By setting the second sealing member 213 as a blocking cover, the second sealing member 213 can be divided into a first chamber 21 and a second chamber 22. When the second sealing member 213 is removed, the lengths of the first chamber 21 and the second chamber 22 are equal to the length of the third chamber 23. Compared with the existing jet assembly 84 that cannot change the internal jet structure, the jet assembly 84 of the present application can select different segmented jet structures in one jet assembly 84 according to usage requirements, which not only effectively reduces manufacturing costs, but also meets different usage requirements of users; of course, in other embodiments, the first sealing member 4 can also be set as a blocking cover like the second sealing member 213, which will not be described in detail here.

[0035] like Figure 3-4 As shown, the first chamber 21 is located between the second chamber 22 and the third chamber 23. The first connecting channel 31 is used to transport gas. Therefore, the nozzle member 4 of the first chamber 21, which is located in the middle position, is in a jetting state throughout the entire process, avoiding the problem of uneven jet transmission. The provision of three chambers 2 provides a wide combustion load range. Moreover, the first chamber 21 is located between the second chamber 22 and the third chamber 23. When the second and third chambers 22, 23 are closed, the jet combustion is minimized and the heating power is low.

[0036] The first gas distribution channel 211 and the second gas distribution channel 212 are arranged on both sides near the bottom of the first chamber 21, and the first gas distribution channel 211 and the second gas distribution channel 212 are arranged downwardly. Since the density of the gas is lower than the density of the air, the gas rises. If the first gas distribution channel 211 and the second gas distribution channel 212 are arranged above both sides of the first chamber 21, it is easy to take away part of the gas, which will cause the jet flame to be not smooth. Therefore, by arranging the first gas distribution channel 211 and the second gas distribution channel 212 on both sides near the bottom of the first chamber 21, the gas is not smooth. The gas can first be fully sprayed out from the nozzle member 4 of the first chamber 21. After the first chamber 21 is filled with gas, it will pass through the first gas distribution channel 211 and the second gas distribution channel 212. This not only makes the chambers 2 interconnected, but also avoids the problem of unsmooth jet transmission. At the same time, the first gas distribution channel 211 and the second gas distribution channel 212 are tilted downward, which also plays a certain guiding role, and can better guide the gas to the second chamber 22 and the third chamber 23, and can also reduce the occurrence of unsmooth jet transmission in the second chamber 22 and the third chamber 23.

[0037] The existing jet assembly 84 is usually composed of two shells forming a accommodating cavity, and then a seal is provided between the two shells, and then the seal is fixed between the two shells by bolts to achieve sealing. Such a setting makes assembly very cumbersome, and it is easy to fix it poorly, resulting in poor sealing effect. In addition, when the seal is aged and damaged, the entire jet assembly 84 needs to be disassembled and assembled when it needs to be replaced, which is very time-consuming and labor-intensive.

[0038] For the reasons described above, the tube body 1 of the present application is integrally formed, and is provided with at least one opening 11 and at least one third sealing member 12 corresponding in number to the number of openings 11. The third sealing member 12 is connected to the opening 11 to seal the tube body 1. The third sealing member 12 is used to seal the tube body 1 to prevent gas leakage, while also facilitating user disassembly and replacement. Furthermore, the integrally formed configuration reduces assembly and disassembly steps, simplifies the structure, reduces installation space, and effectively prevents poor fixing that could affect the sealing effect.

[0039] In this embodiment, two openings 11 and two third sealing members 12 are provided, respectively disposed on both sides of the tube body 1 , and the third sealing member 12 is a blocking cover.

[0040] like Figure 4 As shown, at least one control assembly 7 is connected to the connecting channel 3 to open and close the chamber 2 and control the operating quantity of the nozzle member 4. In this embodiment, two control assemblies 7 are provided. The two control assemblies 7 are connected to the main controller 81 via a first solenoid valve connection line 85 and a second solenoid valve connection line 86, and receive signals to start and stop the control assemblies 7.

[0041] Two control assemblies 7 are provided, each comprising a solenoid valve 71 and a sealing gasket 72. A connector 73 is disposed between the solenoid valve 71 and the sealing gasket 72. The solenoid valve 71 drives the connector 73, which in turn drives the sealing gasket 72 to control the opening and closing of the chamber 2. In this embodiment, the connector 73 is an elastic member, which is a spring. The control assemblies 7 are connected to the second connecting channel 32 and the third connecting channel 33, respectively, to control the opening and closing of the second chamber 22 and the third chamber 23.

[0042] Specifically, the control component 7 is divided into a first control component and a second control component. The first control component includes a first solenoid valve 74 and a first sealing gasket 75, and a first connecting member 76 is provided between the first solenoid valve 74 and the first sealing gasket 75. The second control component includes a second solenoid valve 77 and a second sealing gasket 78, and a second connecting member 79 is provided between the second solenoid valve 77 and the second sealing gasket 78.

[0043] like Figure 2As shown, fixing parts 6 are respectively provided on both sides of the tube body 1, and the fixing parts 6 are connected to the burner 82. A recessed portion 61 is provided on the side of the fixing part 6 along the tube body 1 where the nozzle part 4 is provided, and a fixing part 62 is respectively provided on both sides of the recessed portion 61. Through the provision of the recessed portion 61, materials can be effectively saved, and the recessed portion 61 can avoid the connection with the burner 82, and can also allow air to pass through the recessed portion 61, thereby increasing the primary air volume.

[0044] The jet assembly 84 is divided into three chambers 2, and has a wide combustion load range. While ensuring minimum jet combustion and low heating power, it also simplifies the structure and reduces the installation space.

[0045] In addition, since the tube body 1 has three chambers 2 and is relatively long, the outer surface of the tube body 1 can be provided with reinforcing ribs to enhance the overall strength and avoid breakage during installation and transportation, which will not be described in detail here.

[0046] The wall-mounted boiler 8 has a four-segment structure, that is, by providing three chambers 2, four air-jet modes are realized. The working principle of the wall-mounted boiler 8 is as follows:

[0047] In the first section, the first solenoid valve 74 moves the first sealing gasket 75 through the first connecting part 76 to control the closing of the second connecting channel 32, the first gas distribution channel 211 and the second chamber 22. At the same time, the second solenoid valve 77 moves the second sealing gasket 78 through the second connecting part 79 to control the closing of the third connecting channel 33, the second gas distribution channel 212 and the third chamber 23. The gas is only sprayed out from the nozzle part 4 of the first chamber 21.

[0048] In the second section, the first solenoid valve 74 moves the first sealing gasket 75 through the first connecting part 76 to control the opening of the second connecting channel 32, the first gas distribution channel 211 and the second chamber 22. At the same time, the second solenoid valve 77 moves the second sealing gasket 78 through the second connecting part 79 to control the closing of the third connecting channel 33, the second gas distribution channel 212 and the third chamber 23. The gas is only sprayed out from the nozzle part 4 of the first chamber 21 and the second chamber 22.

[0049] In the third section, the first solenoid valve 74 moves the first sealing gasket 75 through the first connecting part 76 to control the closing of the second connecting channel 32, the first gas distribution channel 211 and the second chamber 22. At the same time, the second solenoid valve 77 moves the second sealing gasket 78 through the second connecting part 79 to control the opening of the third connecting channel 33, the second gas distribution channel 212 and the third chamber 23. The gas is only sprayed out from the nozzle part 4 of the first chamber 21 and the third chamber 23.

[0050] In the fourth section, the first solenoid valve 74 moves the first sealing gasket 75 through the first connecting part 76 to control the opening of the second connecting channel 32, the first gas distribution channel 211 and the second chamber 22. At the same time, the second solenoid valve 77 moves the second sealing gasket 78 through the second connecting part 79 to control the opening of the third connecting channel 33, the second gas distribution channel 212 and the third chamber 23. The gas is ejected from all the nozzle parts 4 of the first chamber 21, the second chamber 22 and the third chamber 23.

[0051] The first chamber 21 has three nozzles 4, the second chamber 22 has three nozzles 4, and the third chamber 23 has six nozzles 4. In the first section, three nozzles 4 are used to generate air. In the second section, thirteen nozzles 4 are used in the first chamber 21 and three nozzles 4 are used in the second chamber 22, for a total of six nozzles. In the third section, thirteen nozzles 4 are used in the first chamber 21 and six nozzles 4 are used in the third chamber 23, for a total of nine nozzles. In the fourth section, twelve nozzles 4 are used in the three chambers 2.

[0052] The technical effects of this utility model are mainly reflected in the following aspects:

[0053] The combustion load range is wide, and the jet structure is simplified while ensuring minimum jet combustion and low heating power.

[0054] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementation methods. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention.
