The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1, according to an embodiment of the present invention, a gas appliance is provided, which includes a heat exchanger 1 disposed at one side of a combustion chamber. The heat exchanger 1 is shown in fig. 1 above the combustion chamber, but in other cases the heat exchanger 1 may be located below the combustion chamber, or even in any orientation of the combustion chamber, as long as the heat exchange requirements are met. The heat exchanger 1 comprises a plurality of parallel liquid pipe sections, radiating fins are distributed on the periphery of each liquid pipe section, and a spoiler 13 is arranged on one side of the heat exchanger 1 away from the combustion chamber and/or between the adjacent radiating fins.

Among them, "the spoiler 13 is disposed on the side of the heat exchanger 1 away from the combustion chamber and/or between the adjacent heat dissipating fins" includes three cases: the first case is to provide the spoiler 13 only on the side of the heat exchanger 1 remote from the combustion chamber; the second case is to provide the spoiler 13 only between the adjacent heat dissipating fins; the third case is to provide a spoiler 13 both on the side of the heat exchanger 1 remote from the combustion chamber and between adjacent fins.

Where "parallel" in the "heat exchanger 1 comprising a plurality of parallel liquid tube sections" comprises "parallel" or "approximately parallel", it is sufficient if the general orientation is the same. For example, in fig. 1, all of the liquid pipe sections run from one of the water boxes to the other.

According to the gas equipment, the spoiler 13 is arranged on one side of the heat exchanger 1 far away from the combustion chamber and/or between the adjacent radiating fins, so that the staying time of high-temperature flue gas in the heat exchanger 1 is prolonged by slowing down the speed of the high-temperature flue gas flowing through the heat exchanger 1 on the premise that the heat exchange area of the heat exchanger 1 is not changed, and the purpose of sufficient heat exchange is achieved. Therefore, the gas equipment can improve the heat exchange efficiency under the structure of controlling the preparation cost of the gas equipment and ensuring the small volume of the gas equipment.

It is worth mentioning that when the high-temperature flue gas flows through the heat exchanger 1 to realize sufficient heat exchange, the required fuel gas in the combustion chamber is correspondingly reduced, so that the escape of the high-temperature flue gas is reduced, and the release of CO or other harmful emissions is effectively reduced.

According to the utility model discloses an embodiment, heat exchanger 1 sets up in the combustion chamber top, and spoiler 13 sets up in heat exchanger 1 top. The spoiler 13 may be a plate structure covering the heat exchanger and having an area similar to the cross-sectional area of the heat exchanger 1. The "cross section of the heat exchanger 1" refers to a section perpendicular to the thickness direction of the heat exchanger 1. In this case, the high-temperature flue gas flows from the combustion chamber to the heat exchanger 1 from the bottom to the top. Before the flue gas is discharged out of the heat exchanger 1, the speed of the flue gas flowing out of the heat exchanger 1 is reduced under the flow blocking effect of the flow blocking plate 13, and further the retention time of the flue gas in the heat exchanger 1 is prolonged, so that the purpose of sufficient heat exchange can be achieved.

Referring to fig. 2, the spoiler 13 includes a plurality of rows of first air holes, and the adjacent rows of first air holes are staggered. Where "staggered" refers to a situation where there is no alignment. For example, in fig. 2, the projections of the first air holes of the first row and the first air holes of the second row in the vertical direction are partially overlapped. Of course, "staggered arrangement" also includes the case where the projections of the first air holes and the second air holes in the vertical direction are not coincident at all.

The spoiler 13 has a simple structure and hardly increases the manufacturing cost of the gas appliance. Moreover, the smoke flowing through the spoiler 13 is distributed more evenly. Of course, the structure of the spoiler 13 is not limited by fig. 2, for example, the first air holes may be rectangular, or may be circular, triangular, hexagonal, etc. Further, the first air holes may be distributed in a centrosymmetric manner, an axisymmetric manner, a matrix distribution, or the like.

The spoiler 13 may be mounted in any manner on the side of the heat exchanger 1 facing away from the combustion chamber. For example, threaded holes may be provided at corresponding positions of the spoiler 13 and the heat exchanger 1, and the spoiler 13 may be fixed to the heat exchanger 1 by a threaded connection. For another example, the spoiler 13 may be welded or glued to the heat exchanger 1. For another example, a snap fit may be provided on the heat exchanger 1, the baffle plate 13 may be mounted on one side of the heat exchanger 1, and the baffle plate 13 may be fixed to the heat exchanger 1 by the snap fit, and so on.

According to another embodiment of the present invention, the spoiler 13 is disposed between the adjacent heat dissipating fins. The adjacent radiating fins can be referred to as adjacent radiating fins on the same liquid pipe section, and can also be referred to as adjacent radiating fins between different liquid pipe sections.

Referring to fig. 3, an airflow channel 12 is formed between the heat dissipation fins of adjacent liquid tube sections, and a spoiler 13 is disposed in the airflow channel 12. At this time, "the spoiler 13 is disposed between the adjacent heat dissipating fins" in which "the adjacent heat dissipating fins" refer to "the adjacent heat dissipating fins" between the different liquid tube sections.

The spoiler 13 disposed in the airflow channel 12 is a plate structure with a shape and a size matched with the cross section of the airflow channel 12, and the plate structure may be provided with or without second air holes. The "cross section of the air flow path 12" refers to a section perpendicular to the height direction of the air flow path 12, and the "height direction of the air flow path 12" may refer to the arrow direction in fig. 3.

Further, the spoilers 13 in the adjacent airflow channels 12 are connected through connecting ribs, and the connecting ribs are arranged corresponding to the gaps between the adjacent radiating fins so as to prevent the connecting ribs and the radiating fins from interfering with each other. By arranging the spoiler 13 in the airflow channel 12, the high-temperature flue gas cannot directly flow out along the airflow channel 12, but more flue gas passes through the heat dissipation fins and exchanges heat with the heat dissipation fins, and then flows out of the heat exchanger 1. In addition, because the spoilers 13 in the adjacent airflow channels 12 are connected through the connecting ribs, the same layer of spoilers 13 in all the airflow channels 12 can be integrally processed and also can be integrally installed, so that the preparation time and the installation time are saved, and the installation cost is reduced.

According to one embodiment of the present invention, the number of the spoilers 13 along the height of the airflow path 12 is plural. By arranging a plurality of spoilers 13, the flue gas in the heat exchanger 1 can be further ensured to be fully dispersed and to exchange heat with the radiating fins.

Wherein, a second air hole is arranged on the baffle plate 13 positioned in the air flow channel 12. Further, at least a portion of the flue gas may be circulated through the second gas stream. When a plurality of baffles 13 are disposed along the height direction of the airflow channel 12, the second air holes of adjacent baffles 13 may be staggered to extend the path of the flue gas.

In this case, the phrase "the second air holes of the adjacent spoilers 13 may be arranged in a staggered manner" refers to a situation where orthographic projections of the second air holes of the adjacent spoilers 13 arranged along the height direction of the air flow passage 12 do not completely coincide with each other.

Referring to fig. 4, when the heat dissipation fins on different liquid tube sections are integrally arranged, the air flow channel 12 is not formed in the heat exchanger 1. In this case, the spoiler 13 may be disposed in the gap between the adjacent heat dissipating fins on the same liquid pipe section.

The spoiler 13 may be fixed to the heat dissipating fin, and the spoiler 13 may correspond to a spoiler structure formed on the heat dissipating fin.

According to the utility model discloses an embodiment, radiating fin is non-planar. Through this kind of non-planar radiating fin, can prolong the flue gas path of flowing through equally for the high temperature flue gas fully exchanges heat after getting into heat exchanger 1, improves high temperature flue gas heat exchange efficiency. For example, the fins may be arcuate and all fins on the same liquid tube section may be arranged in parallel. Also for example, the fins may comprise a plurality of planar plates angled with respect to each other, all fins on the same liquid tube section being arranged in parallel, and so forth.

According to the utility model discloses an embodiment, all liquid pipe sections parallel arrangement are on the coplanar. In this case, the volume of the heat exchanger 1 can be controlled, and the overall volume of the gas appliance can be prevented from being too large.

Referring to fig. 4 and 5, the heat exchanger 1 includes a first water box 2 connected to first ends of all liquid pipe sections and a second water box 3 connected to second ends of all liquid pipe sections, and the first water box 2 and the second water box 3 replace a U-shaped pipe connected to adjacent liquid pipe sections in the conventional technology, so that the manufacturing of the heat exchanger 1 can be simplified and the cost of the heat exchanger 1 can be reduced.

The first water box 2 and the second water box 3 can be arranged by three-in three-out water channels.

Further, the gas equipment also comprises a water inlet pipe 4 and a water outlet pipe 5, and the water inlet pipe 4 and the water outlet pipe 5 are both connected with the first water box 2. With reference to fig. 1, the water inlet pipe 4 and the water outlet pipe 5 are both disposed on the same side of the heat exchanger 1, so that the space on the other side of the gas appliance is saved, the width of the gas appliance can be reduced, and the gas appliance is prevented from being too large in size.

The gas equipment effectively saves the internal space of the gas equipment on the premise of not influencing the hot water performance and the heat exchange area, is convenient to build a small-volume complete machine concept, and well accords with the Chinese market under the current situation of high room price.

In addition, from the aspect of after-sales maintenance, since the water inlet pipe 4 and the water outlet pipe 5 are both arranged on one side of the heat exchanger 1, the process of disassembling the cover plate on the other side of the gas appliance is omitted. Alternatively, a larger maintenance space may be reserved corresponding to the first water box 2 side in consideration of the structural characteristics of the heat exchanger 1 before assembly.

Referring again to fig. 1, the gas appliance further includes a water outlet valve 6, a water inlet valve 7, and a bottom tray 8. Wherein, the water outlet valve 6 is connected with the water outlet pipe 5; the water inlet valve 7 is connected with the water inlet pipe 4; the water outlet valve 6 and the water inlet valve 7 are both fixedly arranged on the bottom tray 8, and a water inlet pipe mounting port and a water outlet pipe mounting port are arranged on the bottom tray 8. Furthermore, the water inlet pipe 4 penetrates through the water inlet pipe mounting port, a water inlet valve 7 is mounted on the portion, located in the gas equipment, of the water inlet pipe 4, and whether water is fed or not is controlled through the water inlet valve 7. Similarly, the water outlet pipe 5 passes through the water outlet pipe mounting port, a water outlet valve 6 is mounted on the part of the water outlet pipe 5 located in the gas equipment, and whether water is discharged or not is controlled through the water outlet valve 6.
