Specifically, the filter member 14 may be made of a metal mesh of a fine mesh structure, such as a stainless steel mesh. It should be understood that in other embodiments, the mesh size and material of the filter screen are not particularly limited.

In one embodiment, the projection of the second outlet 122 onto the plane of the first outlet 112 is at least partially offset from the first outlet 112. The filter element 14 includes a first section 141 and a second section 142 connected to each other and having a smooth transition, the first section 141 being at least partially opposite the first outlet 112, and the second section 142 being at least partially opposite the second inlet 121.

One end of the first section 141 connected with the second section 142 is inclined to the direction close to the second inlet 121 relative to the other end far away from the second section 142; the second section 142 and the transition piece 13 define a swirl zone 15, and a deposition portion 16 for depositing impurities under the action of gravity is formed on the transition portion as a part of the inner wall of the swirl zone 15.

Here, it should be noted that, when the projection of the second outlet 122 on the plane where the first outlet 112 is located is at least partially offset from the first outlet 112: the projection of the second outlet 122 on the plane of the first outlet 112 may be partially offset (partially overlapped) or completely offset from the first outlet 112.

Through the above arrangement, the water flow passes through the filtering element 14 after flowing out from the first outlet 112, because one end of the filtering element 14, which is connected to the first section 141 and the second section 142, is inclined towards the direction close to the second inlet 121 relative to the other end away from the second section 142, and the projection of the second outlet 122 on the plane of the first outlet 112 is at least partially dislocated from the first outlet 112, the impurities, such as silt and rust, filtered by the filtering element 14 can move along the first section 141 towards the direction close to the second outlet 122 along with the impact of the water flow, and the impurities are screwed into the convolution region 15 when passing through the second section 142, and finally are deposited on the deposition portion 16 under the action of gravity to be collected. In the water inlet process, the impurities enter the convolution region 15 and are finally deposited on the deposition part 16 from the convolution region 15, so that the accumulation of the impurities on the filtering piece 14 is reduced, namely the accumulation of the impurities on a flowing water channel is reduced, the gas water heater is ensured to have larger water inlet all the time, and the user experience is improved. Meanwhile, the damage of impurities to the pipeline of the gas water heater is reduced, and the service life of the gas water heater is prolonged.

It is contemplated that in other embodiments, the positional relationship between the liquid inlet member 11 and the liquid outlet member 12 and the positional relationship between the deposition portion 16 and the second section 142 are not limited as long as the impurities can be deposited on the deposition portion 16 by gravity.

In one embodiment, the projection of the second inlet 121 on the plane of the first outlet 112 is completely dislocated from the first outlet 112, the projection of the first section 141 on the plane of the first outlet 112 covers the first outlet 112, the projection of the first section 141 on the plane of the second inlet 121 covers a portion of the second inlet 121, and the projection of the second section 142 on the plane of the second inlet 121 covers the remaining portion of the second inlet 121, so as to ensure that more impurities can enter the convolution region 15 and finally deposit on the deposition portion 16.

Further, the filtering member 14 is in a smooth transition arc shape from the end of the first section 141 connected with the transition piece 13 to the end of the second section 142 connected with the transition piece 13, so that the impurities can conveniently rotate to the rotating area 15 along the filtering member 14. Specifically, one end of the second segment 142 connected to the first segment 141 is inclined with respect to the other end away from the first segment 141 in a direction approaching the second inlet 121. That is, in the present embodiment, the filter member 14 has a circular arc shape with a high center and two low sides.

In another embodiment, the filter member 14 is provided in a flat plate-like configuration. That is, in the present embodiment, the filter member 14 is disposed obliquely upward from an end near the first outlet 112 to an end near the second inlet 121.

It should be understood that in other embodiments, the filter element 14 may have other shapes as long as it is capable of achieving the function of impurities flowing along it and being swirled into the swirling area 15 at the second section 142 during the water flow from the first outlet 112 to the second inlet 121.

In one embodiment, the liquid inlet member 11 has an extending portion 113 extending into the transition member 13, the second section 142, the transition member 14 and the extending portion 113 define a convolution region 15, and the extending portion 113 can block impurities from flowing back into the liquid inlet member 11 again, so as to further reduce the accumulation of the impurities on the filter member 14, ensure that the gas water heater has a large water inlet amount all the time, and improve user experience.

Referring to fig. 2, the purifying apparatus 10 further includes a covering member 17, the deposition portion 16 is provided with a covering opening communicating between the rotation region 15 and the outside, and the covering member 17 is detachably connected to the transition member 13 to open and close the covering opening.

Specifically, the cover 17 includes a cover 171 and a magnetic member 172, the magnetic member 172 is connected to the cover 171, the cover 171 is used to open and close the cover opening, and in a closed state where the cover 171 closes the cover opening, the magnetic member 172 extends into the convolution region 15. The magnetic member 172 can adsorb impurities such as rust, and when the cover 17 is removed, the adsorbed rust can be directly cleaned without cleaning the rust impurities in the convolution region 15 through the cover opening. Specifically, the magnetic member 172 is a magnet. It should be understood that in other embodiments, the cover 17 may omit the magnetic member 172.

With continued reference to fig. 2, another embodiment of the present invention further provides a purification apparatus 10 included in the heat exchange device 100, wherein the water flow flows out from the first outlet 112 and then passes through the filter element 14, because the end of the filter element 14, where the first section 141 is connected to the second section 142, is inclined relative to the other end away from the second section 142 in the direction close to the second inlet 121, and the projection of the second outlet 122 on the plane of the first outlet 112 is at least partially offset from the first outlet 112, the impurities, such as silt and rust, filtered by the filter element 14 will move along the first section 141 in the direction close to the second outlet 122 along with the impact of the water flow, and the impurities will be screwed into the swirl region 15 while passing through the second section 142, and finally deposited on the deposition portion 16 under the action of gravity to be collected. In the water inlet process, the impurities enter the convolution region 15 and are finally deposited on the deposition part 16 from the convolution region 15, so that the accumulation of the impurities on the filtering piece 14 is reduced, namely the accumulation of the impurities on a flowing water channel is reduced, the gas water heater is ensured to have larger water inlet all the time, and the user experience is improved. Meanwhile, the damage of impurities to the pipeline of the gas water heater is reduced, and the service life of the gas water heater is prolonged.
