Abstract
Description
Technical Field
[0001] This application relates to the field of water supply equipment structures. More specifically, this application relates to a hot water supply device designed to provide a flexible and convenient connection between a gas valve and a venturi tube. Background Technology
[0002] Water supply equipment, such as hot water supply units, can be used to treat domestic water, such as providing hot water to residential households. Condensate hot water supply units typically have a gas valve and a venturi tube, with a pipe connection between them. In imported condensate hot water supply units, this pipe connection is usually achieved using rubber hoses, and such a structure does not meet the requirements of Chinese national standards for metal pipe connections. The spatial positions of the gas valve and the venturi tube are misaligned, and the cumulative tolerances after assembly are large. Rigid metal pipes typically cannot flexibly adjust the path and match the spatial distance between the gas valve and the venturi tube. Therefore, there is a continuous need in the art for improved solutions for the internal piping connections of hot water supply units. Summary of the Invention

[0028] Preferred embodiments of this application will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of this application.
[0029] First, it should be noted that the directional terms such as top, bottom, upward, and downward mentioned in this article are defined relative to the directions shown in the various accompanying figures. These directions are relative concepts and will therefore vary depending on their location and state. Therefore, these or other directional terms should not be construed as restrictive.
[0030] Furthermore, it should be noted that any single technical feature described or implied in the embodiments herein, or any single technical feature shown or implied in the accompanying drawings, can be further combined to obtain other embodiments not directly mentioned herein.
[0031] It should be noted that in different figures, the same reference numerals denote the same or substantially the same parts.
[0032] Figures 1 to 4 The diagram illustrates the structure of some components of one embodiment of the hot water supply device of this application. In one embodiment, the hot water supply device may be a wall-mounted boiler. The hot water supply device may include: a pipe connection assembly 10, a venturi tube 20, and a gas valve 30, etc. In one embodiment, the pipe connection assembly 10 is disposed between the venturi tube 20 and the gas valve 30, and establishes fluid communication between the venturi tube 20 and the gas valve 30. Working fluid from the gas valve 20 can be delivered to the venturi tube 20 through the pipe connection assembly 10. In one embodiment, one end of the pipe connection assembly 10 is removably connected to the output port of the gas valve 30, and the other end of the pipe connection assembly 10 is removably connected to the input port of the venturi tube 20.
[0033] The pipe connection assembly 10 may include: a first pipe 100, a second pipe 200, one or more nuts 300, and one or more clamps 400, etc. One end of the first pipe 100 may be detachably connected to one end of the second pipe 200. That is, the first pipe 100 and the second pipe 200 may be separate components, and are detachably connected together in the assembled state. The size of the first pipe 100 may be smaller than the size of the second pipe 200. For example, the outer wall size of the first pipe 100 may be configured to be smaller than or equal to the inner wall size of the second pipe 200, such that one end of the first pipe 100 can be inserted into one end of the second pipe 200 and detachably connected, in such a way that at least a portion of the size of the second pipe 200 is configured to fit over the outside of the first pipe 100.
[0034] The first conduit 100 may have a curved transport path. For example... Figure 3 As shown, the first conduit 100 may include a first section 110, a second section 120, and a third section 130, etc. The first section 110 may extend generally along a first axis A1-A1, the second section 120 may extend generally parallel to the first section 110, and the third section 130 may connect the first section 110 and the second section 120, and extend generally along a second axis A2-A2. A predetermined angle B1 may be formed between the second axis A2-A2 and the first axis A1-A1. A smooth transition shape may be formed between the first section 110 and the third section 130, and between the second section 120 and the third section 130, thereby forming... Figure 3 The first conduit 100 shown is a curved transport path. In one embodiment, the predetermined angle B1 may be between 15 degrees and 75 degrees, such as 15 degrees, 20 degrees, 25 degrees, 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees, 70 degrees, etc.
[0035] The second conduit 200 may include a 90-degree bend structure to form a conveying path with a 90-degree turn. Therefore, the outlets at both ends of the second conduit 200 may have different orientations.
[0036] Nut 300 may be disposed at one end of the first conduit 100, for example, sleeved on the outside of the end of the first section 110. The end of the first section 110 may also include a boss (not shown) to mate with and position nut 300. Nut 300 may have internal threads for attachment to the output port of air valve 30 and for connecting the first conduit 100 to air valve 30.
[0037] An O-ring or sealing ring may be fitted onto the other end of the first pipe 100, for example, onto the outside of the end of the second section 120, to mate with the inner wall of the second pipe 200 to form a sealing connection. In the illustrated embodiment, the O-ring is omitted. It is readily understood that the O-ring may be provided... Figure 3 The O-ring is located in the groove between the two bosses at the end of the second section 120, and the outer diameter of the O-ring may protrude relative to the two bosses.
[0038] The clamp 400 may be disposed outside the second pipe 200. There may be one or more clamps 400, for example, they may be fitted onto a boss on the outer wall of the second pipe 200 to fix the second pipe 200 relative to the inlet port of the venturi tube 20, or to fix the second pipe 200 relative to the first pipe 100.
[0039] The first pipe 100 and the second pipe 200 can be pipe components made of metal. The first pipe 100 and the second pipe 200 can be made of any suitable metallic material, including but not limited to iron, steel, copper alloys, aluminum alloys, etc.
[0040] In use, the curved delivery path of the first pipe 100 allows it to rotate relative to the gas valve 30, and positions the end of the first pipe 100 (i.e., the end of the second section 120) at different locations. After the first pipe 100 is positioned, the user can easily attach the second pipe 200 between the end of the first pipe 100 and the venturi tube 20, thus completing the pipe connection. In this way, the pipe connection assembly and hot water supply device of this application provide a flexible metal pipe connection between the venturi tube 20 and the gas valve 30, which can accommodate different cumulative tolerances and can adapt to the structure of various hot water supply devices.
[0041] The hot water supply device of this application has the advantages of being simple, reliable, easy to implement, and convenient to use, and can provide a flexible and convenient connection between the gas valve and the venturi tube.
[0042] This specification discloses the present application with reference to the accompanying drawings, and also enables those skilled in the art to implement the application, including making and using any device or system, selecting suitable materials, and using any combination method. The scope of this application is defined by the claimed technical solution, but includes other instances that would occur to those skilled in the art. Such other instances shall be considered to fall within the scope of protection defined by the claimed technical solution, provided that they include structural elements that are not different from the literal language of the claimed technical solution, or that they include equivalent structural elements that are not substantially different from the literal language of the claimed technical solution.
