Description

Technical Field

[0001] This utility model relates to the field of gas heater technology, and in particular to a condensate collector that can be used in gas heaters. Background Technology

[0002] Some gas-fired heating and hot water boilers on the market have condensate collection devices with a float in the condensate chamber to seal the condensate outlet. As the amount of condensate inside the condensate chamber increases, the buoyancy of the float increases. When the amount of condensate reaches a certain level, the float is lifted and the condensate outlet is opened.

[0003] However, due to dust and impurities in the condensate or the design of the sealing surface, the float is prone to sticking due to the constantly flowing dirty water in the condensate. In addition, to prevent flue gas leakage, common condensate collectors have multiple U-shaped bends, resulting in a large overall footprint.

[0004] In addition, existing condensate collectors also suffer from poor electrical signal stability and a high probability of false alarms due to different batches of materials. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a condensate collector with a compact structure that can effectively prevent flue gas leakage.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows:

Each partition assembly includes a first partition and a second partition spaced apart, forming an intermediate cavity between the first and second partitions. A water inlet cavity is formed on the side of the first partition facing away from the second partition, and a water outlet cavity is formed on the side of the second partition facing away from the first partition. The lower end of the water inlet cavity communicates with the lower end of the intermediate cavity, and the upper end of the water outlet cavity communicates with the upper end of the intermediate cavity. The collection box is provided with a drain outlet communicating with the lower end of the water outlet cavity and a condensate collection hole communicating with the upper end of the water inlet cavity. A resistance device for reducing water flow is provided in the water inlet cavity.

[0009] In a preferred embodiment of this utility model, a drain outlet is provided at the lower part of the water collection box, and the lower end of the intermediate cavity and the lower end of the water inlet cavity are directly connected to the drain outlet. A drain cover is detachably installed at the drain outlet.

[0010] In a preferred embodiment of this utility model, a connecting cylinder is provided at the drain outlet, and a docking cylinder is provided on the drain cover to be inserted into the connecting cylinder. A sealing structure is provided between the docking cylinder and the connecting cylinder. An axial groove and a circumferential groove are provided on the connecting cylinder. The lower end of the axial groove is open and the upper end is closed. The upper end of the circumferential groove is connected to the upper end of the axial groove. A hanging rod is provided on the outer circumferential wall of the docking cylinder that can pass through the axial groove and enter the circumferential groove.

[0011] In a preferred embodiment of this utility model, the lower side of the circumferential groove is provided with a limiting protrusion that can restrict the hanging rod from entering the axial groove from the circumferential groove, and the space between the limiting protrusion and the upper side of the axial groove is available for the hanging rod to pass through.

[0012] In a preferred embodiment of this utility model, the upper part of the water collection box is provided with a rainwater inlet that is directly connected to the upper end of the water outlet cavity.

[0014] The beneficial effects of this utility model are: the device integrates a serpentine channel in the water collection box, and the overall structure is compact, which helps to reduce the space occupied by it; at the same time, under the resistance of the resistance device and the blocking effect of the first partition, it can prevent the condensate from flowing too fast and carrying the combustion exhaust gas through the water collection box for discharge, and the blocking performance of the flue gas is also excellent.

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings.

[0020] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indicator will also change accordingly. Furthermore, descriptions involving "preferred," "second-preferred," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "preferred" or "second-preferred" may explicitly or implicitly include at least one of those features.

[0021] Reference Figures 1 to 4 This utility model proposes a condensate collector, which includes a hollow water collection box 1. The water collection box 1 is provided with several partition assemblies. The partition assemblies include a first partition 11 and a second partition 12 arranged at intervals. An intermediate cavity 102 is formed between the first partition 11 and the second partition 12. The side of the first partition 11 away from the second partition 12 forms a water inlet cavity 101, and the side of the second partition 12 away from the first partition 11 forms a water outlet cavity 103. The lower end of the water inlet cavity 101 is connected to the lower end of the intermediate cavity 102, and the upper end of the water outlet cavity 103 is connected to the upper end of the intermediate cavity 102. The water collection box 1 is provided with a drain outlet 104 connected to the lower end of the water outlet cavity 103 and a condensate collection hole 105 connected to the upper end of the water inlet cavity 101. A device that can reduce the resistance of water flow is provided in the water inlet cavity 101.

[0022] Specifically, the first partition 11, the second partition 12, and the water collection box 1 are integrally injection molded structures. A water inlet connector is provided at the top of the water collection box 1, and a condensate collection hole 105 is located on the water inlet connector. With this design, the water inlet chamber 101, the intermediate chamber 102, and the water outlet chamber 103 are connected end-to-end to form a serpentine channel. After the condensate enters the water inlet chamber 101 through the water inlet hole, its flow rate slows down under the resistance of the resistance device. It then flows from the lower end of the water inlet chamber 101 into the intermediate chamber 102, then from the upper end of the intermediate chamber 102 into the water outlet chamber 103, and finally exits from the lower end of the water outlet chamber 103 through the drain outlet 104. With this design, a serpentine channel is integrated into the water collection box 1, resulting in a compact overall structure that helps reduce the space it occupies. At the same time, under the resistance of the resistance device and the blocking effect of the first partition 11, the condensate water is prevented from flowing too fast and carrying the combustion exhaust gas through the water collection box 1 for discharge, and the performance of blocking flue gas is also excellent.

[0023] The resistance device includes a water-blocking inner tube 2, which is open at the upper end and closed at the lower end. The upper end of the water-blocking inner tube 2 is connected to the condensate collection hole 105, and a water passage hole 201 is provided on the outer wall of the water-blocking inner tube 2.

[0024] Furthermore, a drain port 106 is provided at the lower part of the water collection box 1. The lower end of the intermediate cavity 102 and the lower end of the water inlet cavity 101 are directly connected to the drain port 106. A drain cover 3 is detachably installed at the drain port 106. With this design, the drain cover 3 can be removed to drain the sewage in the water collection box 1 when needed.

[0025] The water-blocking inner tube 2 can be installed inside the water collection box by welding, snap-fit ​​connection, or screw connection. Preferably, the upper end of the water-blocking inner tube 2 is provided with external threads, and the lower end of the condensate collection hole 105 has internal threads that mate with the external threads. The water-blocking inner tube 2 and the water collection box 1 are detachably connected by the mating of the external and internal threads. The water-blocking inner tube 2 can also be removed through the drain port 106 for cleaning.

[0026] In a preferred embodiment of this utility model, a connecting cylinder 15 is provided at the drain outlet 106, and a docking cylinder 31 inserted into the connecting cylinder 15 is provided on the drain cover 3. A sealing structure is provided between the docking cylinder 31 and the connecting cylinder 15. The sealing structure includes a sealing groove provided on the outer wall of the docking cylinder 31 and a sealing ring installed in the sealing groove. The connecting cylinder 15 is also provided with an axial groove 151 and a circumferential groove 152. The lower end of the axial groove 151 is open and the upper end is closed. The circumferential groove 152 communicates with the upper end of the axial groove 151. A hanging rod 311 is provided on the outer circumferential wall of the docking cylinder 31, which can pass through the axial groove 151 and enter the circumferential groove 152. A limiting protrusion 153 is provided on the lower side of the circumferential groove 152, which can restrict the hanging rod 311 from entering the axial groove 151 from the circumferential groove 152. The space between the limiting protrusion 153 and the upper side of the axial groove 151 is available for the hanging rod 311 to pass through. This design makes the drain cover 3 easy to install and remove. To remove the drain cover 3, simply rotate it a certain angle so that the hanging rod 311 moves from the circumferential groove 152 into the axial groove 151, and then pull the drain cover 3 directly downwards. This is convenient and quick. Alternatively, the drain cover 3 and the connecting cylinder 15 can also be connected via pipe threads. However, compared to pipe threads, the above connection structure avoids the problem of sludge settling in the condensate water jamming the threads, making it more reliable.

[0027] Furthermore, a rainwater connector 4 is provided at the upper part of the water collection box 1, and a rainwater inlet 107 is provided on the rainwater connector 4, which is directly connected to the upper end of the water outlet chamber 103. An inclined drain pipe 17 is provided at the lower part of the water collection box 1, the upper end of the drain pipe 17 is directly connected to the lower end of the water outlet chamber 103, and the drain outlet 104 is the lower end of the drain pipe 17. A pressure relief connector is provided in the middle of the drain pipe 17, and the pressure relief connector has an upward-opening pressure relief valve connection hole 108. With this design, rainwater collected from the outside and water discharged from the pressure relief valve can be concentrated and discharged into the drain outlet 104 of the water collection box 1, which can serve multiple purposes and simplify the structure of the gas heater.

[0028] Reference Figure 4 An installation plate is integrally connected to the outer surface of the water collection box. When the water collection box is used on a gas furnace, it is fixedly installed on the W-structure bottom tray 5 of the gas furnace through the installation plate.

[0029] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
