Description

Technical Field

[0001] This utility model relates to the field of heat exchange technology, and in particular to a condenser shell, a condenser heat exchange device, and a gas-fired hot water equipment. Background Technology

[0002] Gas-fired water heaters heat water by passing the high-temperature flue gas generated by gas combustion through a heat exchanger, thereby exchanging heat between the flue gas and the water flowing through the exchanger. To fully utilize the heat from the flue gas, condensing gas-fired water heaters are becoming increasingly widely used.

[0003] Condensing gas-fired water heaters, compared to conventional gas-fired water heaters, incorporate a condensing heat exchange device. Existing technology provides such a device, which includes a condensing shell, a condensing heat exchanger, and an atomizer. The condensing shell comprises a condensing heat exchanger shell with a condensing chamber, an atomizing shell with an atomizing chamber, and a flue gas shell with an exhaust chamber. The exhaust gas shell is connected to the upper part of the atomizing shell, and the exhaust chamber communicates with the atomizing chamber. The condensing heat exchanger shell is located on one side of the exhaust gas shell, and the side of the exhaust chamber communicates with the condensing chamber. A flue gas inlet is provided on the side of the condensing heat exchanger shell away from the exhaust chamber, and a flue gas outlet is provided at the upper end of the exhaust chamber on the exhaust gas shell. The condensing heat exchanger and the atomizer are both located within the condensing chamber. After heat exchange in the main heat exchanger, the flue gas enters the condensation chamber through the inlet and is condensed and cooled. The cooled flue gas then flows into the exhaust chamber. The condensate formed flows into the atomizing chamber and is atomized by the atomizer to form water mist. The water mist is sprayed upwards into the exhaust chamber and mixes with the flue gas in the exhaust chamber to form relatively large smoke particles. The smoke is then discharged outwards through the exhaust port.

[0004] In existing condensation heat exchange devices, the lower end of the exhaust chamber and the upper end of the atomizing shell are spaced apart to form a gap channel, through which the condensation chamber communicates with the exhaust chamber. However, as the flue gas flows into the gap channel, the lateral flow of the flue gas obstructs the flow of water mist in the atomizing chamber. This causes the upward-sprayed water mist to experience flow inhibition under the pressure of the flue gas flow, resulting in a reduction in the amount and speed of water mist ejected from the atomizing chamber, and even affecting the formation of water mist. Consequently, the mixing effect between water mist and flue gas is weakened, leading to poor mixed emission of flue gas and water mist. Utility Model Content

[0005] One of the technical problems solved by this utility model is to provide a condensation shell that can effectively solve the problem of the interference of flue gas flow on water mist formation and flow in the prior art, and improve the mixing and emission effect of flue gas and water mist.

[0006] The second technical problem solved by this utility model is to provide a condensation heat exchange device that can effectively solve the problem of the interference of flue gas flow on water mist formation and flow in the existing technology, and improve the mixing and emission effect of flue gas and water mist.

[0007] The third technical problem solved by this utility model is to provide a gas-fired hot water device that can effectively solve the problem of the interference of flue gas flow on water mist formation and flow in the existing technology, and improve the mixing and emission effect of flue gas and water mist.

[0008] The first technical problem mentioned above is solved by the following technical solution:

The upper end of the atomizing housing and the lower end of the exhaust chamber are spaced apart to form a communication gap, the communication gap communicating with the condensation chamber.

[0010] Compared with the prior art, the condenser shell of this utility model has the following advantages: By providing a guide plate with a flow guide at the upper end of the atomizing shell, and the flow guide plate is inclined from bottom to top towards the center of the flow guide, the flue gas flowing out of the condensing chamber can be guided upward to the exhaust chamber, avoiding the horizontal or downward flow of flue gas that would suppress the upward flow of water mist in the atomizing chamber, ensuring that both flue gas and water mist can flow smoothly into the exhaust chamber, thereby achieving their mixing and upward flow; at the same time, the provision of the flow guide plate can also facilitate the upward flow of water mist. The flow is guided, reducing the probability of water mist flowing to the outside of the exhaust chamber and improving the atomization effect of the flue gas. By setting a first snap-fit ​​structure on the mounting part and a second snap-fit ​​structure on the upper end of the atomizing shell, the first and second snap-fit ​​structures are snapped together, which facilitates the disassembly and assembly of the flow guide relative to the atomizing shell.

[0015] In one embodiment, one of the first snap-fit ​​structure and the second snap-fit ​​structure is a snap-fit ​​protrusion, and the other is a snap-fit ​​groove, wherein the snap-fit ​​protrusion is snapped into the snap-fit ​​groove;

[0016] Alternatively, the first snap-fit ​​structure is a hook protruding from the lower end of the second mounting portion, and the second snap-fit ​​structure is a protrusion protruding from the upper end of the atomizing housing, with the hook snapping into the lower end of the protrusion.

[0017] In one embodiment, the mounting portion is a rectangular ring structure, and each side of the mounting portion is provided with a plurality of first snap-fit ​​structures at intervals along the extending direction.

[0018] In one embodiment, the mounting portion is a rectangular ring structure, and one guide plate is provided on each of the four sides of the mounting portion, and the guide plate portion is integrally formed with the mounting portion.

[0019] In one embodiment, the mounting part is a rectangular ring structure, and one guide plate is provided on each of the four sides of the mounting part.

The atomizer is installed inside the atomization shell, and the atomizer's mist outlet is oriented towards the flow guide. The condensation heat exchanger is disposed in the condensation chamber.

[0043] Example 1

[0044] This embodiment provides a condensing heat exchange device that can be applied to gas-fired water heaters to reduce the disassembly, assembly, and maintenance costs of the condensing heat exchange device and the gas-fired water heaters, and to improve the performance of the condensing heat exchange device.

[0045] like Figure 1 and Figure 2 As shown, in this embodiment, the condensation heat exchange device includes a condenser shell 100, a condenser heat exchanger 200, and an atomizer 400. The condenser shell 100 includes a smoke exhaust shell 3, an atomizing shell 1, and a condenser heat exchange shell 4. The smoke exhaust shell 3 is connected to the upper part of the atomizing shell 1 and has a smoke exhaust chamber 33 inside. The upper end of the smoke exhaust shell 3 is provided with a smoke exhaust port 34 that communicates with the smoke exhaust chamber 33. The atomizing shell 1 has an atomizing chamber 11 inside. The upper end of the atomizing chamber 11 communicates with the smoke exhaust chamber 33, and a water inlet is provided on the side. The condenser heat exchange shell 4 is connected to the side of the smoke exhaust shell 3 and has a condenser chamber 41. The condenser heat exchange shell 4 is provided with a smoke inlet 42 that communicates with the condenser chamber 41. The lower end of the smoke exhaust chamber 33 communicates with the condenser chamber 41. The condenser heat exchanger 200 is disposed in the condenser chamber 41, and both ends of the condenser heat exchanger 200 extend out of the condenser shell 100. The atomizer 400 is installed in the atomizing chamber 11, and the water inlet of the atomizer 400 communicates with the atomizing chamber 11. The mist outlet of the atomizer 400 is set upward.

[0046] After being heated by the main heat exchanger of the gas-fired hot water equipment, the flue gas enters the condensing chamber 41 through the flue gas inlet 42 and is cooled by heat exchange with the condensing heat exchanger 200. The cooled flue gas flows into the exhaust chamber 33 through the lower end of the exhaust chamber 33, which is connected to the condensing chamber 41. The condensed water flows into the atomizing chamber 11 through the water inlet. The water in the atomizing chamber 11 is atomized by the atomizer 400 to form water mist, which is then sprayed upwards into the exhaust chamber 33 and mixed with the flue gas in the exhaust chamber 33 to form smoke. The smoke is discharged through the exhaust port 34.

[0047] In one embodiment, the condenser housing 100 further includes a filter housing 5 connected to the lower end of the condenser heat exchange housing 4. One side of the filter housing 5 is connected to the atomizing housing 1. A filter chamber is provided inside the filter housing 5, and a filter 300 is installed inside the filter chamber. The filter chamber is connected to the atomizing chamber 11 through a water inlet. The upper end of the filter chamber is connected to the condenser chamber 41. The condensed water formed by condensation flows downward into the filter chamber and is filtered by the filter 300. The filtered condensed water flows into the atomizing chamber 11 through the water inlet. By setting the filter 300, the problem of excessive corrosiveness of the condensed water leading to direct discharge and significant environmental pollution can be avoided. The filter 300 can be, but is not limited to, existing structures capable of condensed water filtration such as a neutralizer.

[0048] The exhaust housing 3 includes an exhaust outer shell 31 and an exhaust inner shell 32. The exhaust outer shell 31 is connected to the upper part of the condensing heat exchange shell 4 and the atomizing shell 1. The exhaust inner shell 32 is inserted inside the exhaust outer shell 31 and its upper end extends out of the exhaust outer shell 31. The exhaust inner shell 32 surrounds and forms an exhaust cavity 33. The outer wall of the exhaust inner shell 32 facing the condensing heat exchanger 200 forms one side cavity wall of the condensing cavity 41. The exhaust inner shell 32 and the upper end of the atomizing shell 1 are spaced apart so that a communication gap is formed between the upper ends of the exhaust inner shell 32 and the atomizing shell 1. The condensing cavity 41 and the exhaust cavity 33 are connected through this communication gap.

[0049] It is worth noting that the specific structures of the exhaust housing 3, the atomizing housing 1, the condensing heat exchange housing 4, and the filter housing 5, as well as the specific structures of the atomizer 400, the condensing heat exchanger 200, and the filter 300, and their installation structures within the condensing housing 100, can all be set with reference to existing technologies. This is not the focus of this utility model, and will not be limited or elaborated here.

[0050] like Figures 2 to 4 As shown, the upper end of the atomizing housing 1 extends into the interior of the exhaust housing 3. The condensation housing 100 also includes a flow guide 2, which is installed at the upper end of the atomizing housing 1. Specifically, the flow guide 2 includes an annular mounting portion 21 and a flow guide plate portion 22 connected to the upper end of the mounting portion 21. A first snap-fit ​​structure 27 is provided on the mounting portion 21, and a second snap-fit ​​structure 12 is provided at the upper end of the atomizing housing 1. The first snap-fit ​​structure 27 and the second snap-fit ​​structure 12 snap together. The flow guide plate portion 22 is arranged from top to bottom towards the center of the flow guide 2.

[0051] The condenser housing 100 provided in this embodiment, by providing a guide member 2 with a guide plate portion 22 at the upper end of the atomizing housing 1, and the guide plate portion 22 being inclined from bottom to top towards the center of the guide member 2, can guide the flue gas flowing out of the condenser chamber 41 to flow upward into the exhaust chamber 33, avoiding the horizontal or downward flow of flue gas causing suppression of the upward flow of water mist in the atomizing chamber 11, ensuring that both flue gas and water mist can flow smoothly into the exhaust chamber 33, thereby achieving the mixing and upward flow of the two; at the same time, the provision of the guide plate portion 22 can also provide guidance for the flow of water mist, reducing water mist The probability of the gas flowing to the outside of the exhaust chamber 33 is increased, thus improving the atomization effect of the flue gas. By setting a first snap-fit ​​structure 27 on the mounting part 21 and a second snap-fit ​​structure 12 on the upper end of the atomizing shell 1, the first snap-fit ​​structure 27 and the second snap-fit ​​structure 12 are snapped together, which facilitates the disassembly and assembly of the guide component 2 relative to the atomizing shell 1. That is, the guide component 2 can be processed and produced separately from the atomizing shell 1, which facilitates the processing, disassembly, replacement and maintenance of the guide component 2, improves the design and ease of use of the guide component 2, simplifies the structure of the condensing shell 100, and reduces the replacement and maintenance cost of the condensing shell 100.

[0052] To further improve the installation efficiency of the guide component 2, in one embodiment, the mounting portion 21 includes a first mounting portion 211 and a second mounting portion 212 connected at an included angle. The first mounting portion 211 abuts against the upper end surface of the atomizing housing 1, and a first snap-fit ​​structure 27 is disposed on the second mounting portion 212. By providing the first mounting portion 211 and abutting against the upper end surface of the atomizing housing 1, when the guide component 2 is assembled onto the atomizing housing 1, the mounting position of the guide component 2 relative to the atomizing housing 1 can be positioned by the abutment between the first mounting portion 211 and the upper end of the atomizing housing 1, thereby achieving assembly positioning of the two and improving assembly accuracy and assembly efficiency.

[0053] In one embodiment, the second mounting portion 212 has an annular structure and engages with the upper end of the atomizing housing 1, thereby further improving the assembly stability and reliability of the guide member 2 and the atomizing housing 1. In other embodiments, the first mounting portion 211 may also have an annular structure, and multiple second mounting portions 212 may be provided at circumferential intervals along the first mounting portion 211.

[0054] In one embodiment, one of the first snap-fit ​​structure 27 and the second snap-fit ​​structure 12 is a snap-fit ​​protrusion and the other is a snap-fit ​​groove. The snap-fit ​​protrusion is snapped into the snap-fit ​​groove, thereby simplifying the connection structure between the two and improving the stability of the assembly.

[0055] In one embodiment, such as Figure 3 As shown, the second mounting part 212 is located inside the upper end of the atomizing housing 1. The first snap-fit ​​structure 27 is a snap-fit ​​protrusion, and the second snap-fit ​​structure 12 is a snap-fit ​​groove. The groove has a bottom to prevent water mist leakage caused by the groove penetrating the upper end of the atomizing housing 1.

[0056] In another embodiment, such as Figure 5 and Figure 6 As shown, the second mounting part 212 is located inside the upper end of the atomizing housing 1, and the first snap-fit ​​structure 27 is a slot that extends laterally through the second mounting part 212.

[0057] In yet another embodiment, such as Figure 7 The second mounting part 212 shown is located on the upper outer side of the atomizing housing 1. The first snap-fit ​​structure 27 is a snap-fit ​​protrusion, and the second snap-fit ​​structure 12 is a snap-fit ​​groove.

[0058] In yet another embodiment, such as Figure 8 As shown, the first snap-fit ​​structure 27 is a hook that protrudes from the lower end of the second mounting part 212, and the second snap-fit ​​structure 12 is a protrusion that protrudes from the upper end of the atomizing housing 1, with the hook snapping into the lower end of the protrusion.

[0059] To improve the installation stability and reliability of the atomizing housing 1, in one embodiment, a plurality of first snap-fit ​​structures 27 are provided at intervals along the extending direction on each side of the mounting portion 21. In other embodiments, the first snap-fit ​​structures 27 may be provided on opposite sides of the mounting portion 21.

[0060] To further improve assembly stability, in one embodiment, a sealing ring groove is provided on the lower side of the first mounting part 211, and an elastic pad is provided in the sealing ring groove. The elastic pad is sandwiched between the bottom of the sealing ring groove and the upper end of the atomizing housing 1. This arrangement can fill the assembly gap between the first mounting part 211 and the upper end of the atomizing housing 1 by providing the sealing pad, thereby limiting the vertical shaking that occurs after the first snap-fit ​​structure 27 and the second snap-fit ​​structure 12 are engaged, and enhancing the tightness of the engagement between the first snap-fit ​​structure 27 and the second snap-fit ​​structure 12.

[0061] In another embodiment, a sealing ring groove is provided at the upper end of the atomizing housing 1, and an elastic pad is provided in the sealing ring groove. The elastic pad is sandwiched between the bottom of the sealing ring groove and the first mounting part 211.

[0062] like Figure 1 and Figure 4 As shown, in one embodiment, the mounting portion 21 has a rectangular ring structure, and one guide vane portion 22 is provided on each of the four sides of the mounting portion 21, with the four guide vane portions 22 joined end to end. This facilitates making the guide vane portions 22 on the four sides of the mounting portion 21 consistent, simplifying the assembly of the guide vane portions 22. In another embodiment, the four guide vane portions 22 can be disposed separately.

[0063] In one embodiment, the guide plate portion 22 and the mounting portion 21 are integrally formed, so that the entire guide member 2 is a one-piece structure, reducing assembly difficulty. In other embodiments, the guide plate portion 22 can also be detachably connected to the mounting portion 21. The detachable connection method can be, but is not limited to, using screws, plugs, or snaps.

[0064] To further improve the assembly stability and reliability of the guide component 2 on the atomizing housing 1, in one embodiment, fixing posts 23 are connected downwards at the four corners of the mounting portion 21. Mounting bosses 13 protrude from the inner sides of each of the four corners of the atomizing housing 1, with each mounting boss 13 corresponding to a fixing post 23. A fixing through hole 26 is provided through the fixing post 23, and a threaded hole is provided on each mounting boss 13, directly opposite the fixing through hole 26. The fixing post 23 and the corresponding mounting boss 13 are connected by fasteners passing through the fixing through hole 26 and the threaded hole. This arrangement allows the snap-fit ​​between the mounting portion 21 and the atomizing housing 1 to serve as a pre-installation for assembling the guide component 2 onto the atomizing housing 1, achieving the installation positioning and limiting of the guide component 2 on the atomizing housing 1. This facilitates the positioning and fastening of the fixing posts 23 and the mounting bosses 13, improving assembly efficiency.

[0065] This embodiment also provides a gas-fired water heater, including the aforementioned condensing heat exchanger. By employing the aforementioned condensing heat exchanger, the gas-fired water heater provided in this embodiment can reduce the processing and maintenance costs of the gas-fired water heater and improve the user experience.

[0066] It is worth noting that the assembly structure of the condensing heat exchanger in the gas-fired water heater and other structures in the gas-fired water heater can be set with reference to the existing technology. This is not the focus of the improvement of this utility model, and will not be elaborated here.

[0067] Example 2

[0068] This embodiment provides a condensation heat exchange device, and the condensation heat exchange device provided in this embodiment has the same basic structure as the condensation heat exchange device in the above embodiment, with only some differences in the settings. This embodiment will not describe the same structure as the above embodiment again.

[0069] like Figure 9 and Figure 10 As shown, in this embodiment, one guide plate portion 22 is provided on each side of the mounting portion 21, each guide plate portion 22 is detachably connected to the mounting portion 21, and the included angle of the guide plate portion 22 relative to the vertical direction can be adjusted.

[0070] That is, the condensation heat exchange device provided in this embodiment has a guide plate portion 22 that is detachably connected to the mounting portion 21, and the angle between the guide plate portion 22 and the vertical direction can be adjusted. Therefore, the angle between the guide plate portion 22 and the vertical plane can be adjusted according to the flow guidance requirements, thereby better satisfying the flow guidance effect of water mist and flue gas.

[0071] In this embodiment, both ends of the guide plate portion 22 are rotatably mounted on the mounting portion 21, and the rotation axis of the guide plate portion 22 is set horizontally. Thus, the angle of the guide plate portion 22 relative to the vertical direction can be adjusted by rotating the guide plate portion 22 relative to the mounting portion 21.

[0072] In other embodiments, the angle between the guide plate portion 22 and the mounting portion 21 and the vertical direction can be adjusted during the assembly process. For example, the guide plate portion 22 has a fixed shaft protruding from both ends, and the sidewall of the fixed shaft has a rib protruding from it. The rib can be one or multiple ribs spaced apart circumferentially along the fixed shaft. The mounting portion 21 has a main shaft hole at a corresponding position, and the wall of the main shaft hole has limiting holes spaced apart circumferentially along the main shaft hole. The fixed shaft can be inserted into the main shaft hole, and the rib can be inserted into any of the limiting holes. Thus, by selectively inserting the rib into one of the limiting holes, the angle of the guide plate portion 22 can be adjusted.

[0073] To improve the ease of installation of the guide vane section 22, bosses 213 protrude upwards from the four corners of the mounting section 21. Both ends of the guide vane section 22 are rotatably mounted on the bosses 213 to ensure that the guide vane section 22 is positioned higher than the first mounting section 211. Specifically, the bosses 213 are connected to the first mounting section 211.

[0074] Specifically, the boss portion 213 has a pivot hole 2131, and the two ends of the guide plate portion 22 have protruding mounting shafts 24, which are rotatably inserted into the pivot hole 2131. That is, each boss portion 213 has a pivot hole 2131 on the side facing the adjacent boss portion 213.

[0075] To better ensure that the guide plate section 22 is fixed at the adjusted angle after the angle adjustment is completed, a locking structure is also provided between the guide plate section 22 and the mounting section 21. The locking structure limits the guide plate section 22 to the adjusted angle, preventing the guide plate section 22 from shaking during the use of the condensing heat exchange device, thereby improving the stability and reliability of the condensing heat exchange device.

[0076] In one embodiment, the locking structure includes a limiting protrusion 25 protruding from the side of the guide plate portion 22 and a limiting groove 2132 formed on the boss portion 213. Multiple limiting grooves 2132 are provided at intervals around the rotation axis of the guide plate portion 22. The limiting protrusion 25 can be locked in any of the limiting grooves 2132, thereby preventing the guide plate portion 22 from shaking.

[0077] In other embodiments, the locking structure may include a locking threaded hole provided on the guide plate portion 22 and an arc-shaped fastening hole provided on the boss portion 213, the center of the arc-shaped fastening hole being located on the rotation axis of the guide plate portion 22; the locking structure may also include a threaded fastener, the threaded fastener passing through the arc-shaped fastening hole and being threaded into the locking threaded hole.
