[0029] An air heat recovery and purification device, such as Figure 1 and Figure 2 As shown, it includes a shell 1, on which are provided: an exhaust inlet 2, through which indoor exhaust gas enters the shell 1; a fresh air inlet 3, through which outdoor air enters the shell 1; a heat exchanger 4, in which indoor exhaust gas and outdoor air perform heat exchange; an exhaust outlet 5, at which an exhaust blower 7 is provided, and the exhaust blower 7 blows the indoor exhaust gas after heat exchange out of the exhaust outlet 5 to the outside; a fresh air outlet 6, at which a fresh air blower 8 is provided, and the fresh air blower 8 blows the outdoor air after heat exchange into the room from the fresh air outlet 6.

[0030] The shell 1 is specifically in the shape of a cuboid, the exhaust inlet 2 and the fresh air outlet 6 are arranged on the same side of the shell 1 , the exhaust outlet 5 and the fresh air inlet 3 are also arranged on the same side of the shell 1 and are located on the side opposite to the exhaust inlet 2 .

[0031] A first installation chamber 10 and a second installation chamber 11 are provided in the shell 1, the fresh air blower 8 is installed in the first installation chamber 10, the fresh air outlet 6 is opened on the side wall of the first installation chamber 10, and the air outlet of the fresh air blower 8 is opposite to the fresh air outlet 6; the exhaust blower 7 is installed in the second installation chamber 11, the exhaust outlet 5 is opened on the side wall of the second installation chamber 11, and the air outlet of the exhaust blower 7 is opposite to the exhaust outlet 5.

[0032] like Figure 2 and Figure 3 As shown, the heat exchanger 4 is specifically in a diamond shape, and the edges of the heat exchanger 4 are fixed in the shell 1 by fixing strips and screws. The two upper surfaces of the heat exchanger 4 are respectively an exhaust air inlet surface 16 and a fresh air inlet surface 18, and the two lower surfaces are respectively an exhaust air outlet surface 17 and a fresh air outlet surface 19. Indoor exhaust gas enters the heat exchanger 4 from the exhaust air inlet surface 16, and outdoor air enters the heat exchanger 4 from the fresh air inlet surface 18. After heat is transferred through the heat exchanger 4, the indoor exhaust gas is discharged from the exhaust air outlet surface 17, and the outdoor air is discharged from the fresh air outlet surface 19.

[0033] An air guide plate 15 is provided between the exhaust inlet 2 and the heat exchanger 4 and between the fresh air inlet 3 and the heat exchanger 4. The air guide plate 15 is inclined and has a separation effect, ensuring that after the indoor exhaust gas enters the shell 1 from the exhaust inlet 2, it enters the exhaust inlet surface 16 along the air guide plate 15, and after the outdoor air enters the shell 1 from the fresh air inlet 3, it enters the fresh air inlet surface 18 along the air guide plate 15.

[0034] The first installation chamber 10 and the second installation chamber 11 are open on one side facing the heat exchanger 4 and are both provided with a baffle 20 . The baffle 20 also serves as a partition to ensure that the fresh air blower 8 draws air from the fresh air outlet 19 , while the exhaust blower 7 draws exhaust gas from the exhaust outlet 17 .

[0035] like Figure 3 and Figure 4 As shown, a purification component 9 is also provided in the shell 1, and the purification component 9 is arranged between the heat exchanger 4 and the fresh air blower 8. The outdoor air after heat exchange passes through the purification component 9 and enters the fresh air blower 8, and the impurities in the outdoor air or the impurities entrained during heat exchange with the exhaust gas are filtered out to maintain the indoor air quality.

[0036] An installation frame 12 is provided inside the shell 1 and between the heat exchanger 4 and the first installation chamber 10. The installation frame 12 is locked to the inner wall of the shell 1 by screws. The purification component 9 is detachably connected to the installation frame 12. The installation frame 12 has a sliding groove 13. The purification component 9 is slidably connected to the sliding groove 13. One side of the installation frame 12 is open, and the purification component 9 can be inserted into the sliding groove 13 from this side, or pulled out from the sliding groove 13 to achieve a detachable connection.

The ozone filter faces the fresh air blower 8, and the primary filter faces the heat exchanger 4. After being discharged from the heat exchanger 4, the air passes through multiple filters in sequence and then enters the fresh air blower 8, thereby purifying various pollutants in the air and keeping the air fresh.

[0039] The working process of the utility model is as follows:

[0040] After the indoor exhaust gas enters the shell 1 from the exhaust inlet 2, it enters the heat exchanger 4 from the exhaust inlet surface 16. After the outdoor air enters the shell 1 from the fresh air inlet 3, it enters the heat exchanger 4 from the fresh air inlet surface 18. The indoor exhaust gas transfers the residual heat to the outdoor air through the heat exchanger 4. Then the indoor exhaust gas is discharged from the exhaust outlet surface 17 of the heat exchanger 4 and discharged to the outside through the exhaust outlet 5. The outdoor air is discharged from the fresh air outlet surface 19 of the heat exchanger 4, filtered by the purification component 9, and discharged into the room through the fresh air outlet 6.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
