As shown in fig. 3, the air path switching unit 16 is configured to switch the exhaust air inlet 113 or the supply air inlet 111 from an open state to a closed state or from a closed state to an open state. That is, the air path switching plate (not shown) in the air path switching unit 16 moves to allow air to enter the casing 11 through the exhaust air inlet 113 or the supply air inlet 111.

On the contrary, when the air path switching plate 161 is at the second position, it opens the exhaust air inlet 113 and closes the supply air inlet 111, so that the air enters the housing 11 through the exhaust air inlet 113.
In the present embodiment, the abutment surface 149 of the heat exchange unit 14 comprises two acute angles a, including the following two embodiments:
embodiment 1: as shown in fig. 4, an angle between a surface on which the exhaust air inlet 143 is located and a surface on which the supply air outlet 142 is located is an acute angle a, and an angle between a surface on which the exhaust air outlet 144 is located and a surface on which the supply air inlet 141 is located is an acute angle a. That is, the angle between the long side 1491 on the upper side of the abutment surface 149 and the short side 1494 on the right side is an acute angle a, and the angle between the long side 1492 on the lower side of the abutment surface 149 and the short side 1493 on the left side is an acute angle a.
Embodiment 2: an angle between a surface on which the exhaust air inlet 143 is located and a surface on which the supply air inlet 141 is located is an acute angle a, and an angle between a surface on which the exhaust air outlet 144 is located and a surface on which the supply air outlet 142 is located is an acute angle a. That is, the angle between the long side 1491 on the upper side of the abutment surface 149 and the short side 1493 on the left side is an acute angle a, and the angle between the long side 1492 on the lower side of the abutment surface 149 and the short side 1494 on the right side is an acute angle a.
As shown in fig. 3 and 4, when the heat exchange unit 14 is a parallelepiped and the abutment surface 149 is a parallelogram including two acute angles a, in the case where the abutment surface 149 of the present embodiment is the same in area as the rectangular abutment surface, the circumference of the abutment surface 149 of the parallelogram is larger than the circumference of the rectangular abutment surface. That is, when the abutment surface 149 of the present embodiment is identical in area to the rectangular abutment surface, when one set of sides of the parallelogram including the two acute angles a is identical to one set of sides of the rectangle, the other set of sides of the parallelogram including the two acute angles a may be longer than the other set of sides of the rectangle. That is, when the heat exchange unit 14 of the present embodiment is the same in volume as the heat exchange unit of the background art, and the area of the exhaust air outlet 144 is the same, the air supply air outlet 142 of the heat exchange unit 14 of the present embodiment is larger than the area of the air supply air outlet of the heat exchange unit of the background art. Since the heat exchange efficiency depends on the amount of air passing through the heat exchange unit, the amount of air passing through the heat exchange unit is related to the areas of the air supply exhaust port, the air supply intake port, the exhaust port, and the exhaust intake port, that is, in the case where the areas of the exhaust port and the exhaust intake port are constant, the larger the areas of the air supply exhaust port and the air supply intake port are, the larger the amount of air in the heat exchange unit is, and conversely, the smaller the areas of the air supply exhaust port and the air supply intake port are, the smaller the amount of air in the heat exchange unit is. Therefore, since the air supply exhaust port 142 and the air supply inlet port of the heat exchange unit 14 of the present embodiment have larger areas than the air supply exhaust port and the air supply inlet port of the heat exchange unit of the background art, the heat exchange unit 14 of the present embodiment can improve the heat exchange efficiency compared to the background art.
In the present embodiment, as in the related art, the exhaust fan 18 is disposed on the side of the heat exchange unit 14 in order to ensure the smoothness of the air passage. When the above embodiment 1 is employed, the exhaust fan 18 is placed on the left side of the heat exchange unit 14, i.e., on the downstream side of the exhaust outlet 144 of the heat exchange unit 14, in the perspective of fig. 5. Since the heat exchange unit 14 of the present embodiment includes the abutment surfaces 149 of a parallelogram shape, the abutment surfaces 149 include two acute angles a, and the angles on the abutment surfaces 149 are not equal to 90 °, that is, at least one set of the sides of the abutment surfaces 149 is obliquely disposed in the housing 11, that is, one set of long sides or one set of short sides of the abutment surfaces 149 is obliquely disposed in the housing 11.
As in the related art, when the supply air outlet is arranged parallel to the bottom surface, the longest width thereof is only the same as the width of the housing in the horizontal direction.
The present embodiment, however, has the air supply outlet 142 inclined with respect to the bottom surface 115 of the housing 11. That is, the top surface 145 of the heat exchange unit 14 is disposed obliquely with respect to the bottom surface 115 of the case 11, or the long sides 1491, 1492 of the upper and lower sides of the abutment surface 149 are disposed obliquely. Therefore, in the case where the width of the housing 11 in the horizontal direction is the same, the air supply outlet 142 of the present embodiment can be set longer, that is, the width of the air supply outlet 142 of the present embodiment is larger, because it is disposed obliquely with respect to the bottom surface 115 of the housing 11, as compared to the air supply outlet horizontally disposed in the related art. The maximum width of the air supply exhaust port 142 of the present embodiment is larger than the width of the housing 11 in the horizontal direction. The width of the housing 11 in the horizontal direction means a wide length parallel to the bottom surface of the housing. The horizontal direction refers to the left and right direction of the viewing angle of fig. 5.
That is, when the exhaust fan 18 is disposed at the side of the heat exchange unit 14, it is not necessary to reduce the width of the heat exchange unit as in the background art, and the exhaust fan 18 can be disposed at the side of the heat exchange unit 14 even when the width of the housing 11 in the horizontal direction and the area of the supply air outlet 142 of the heat exchange unit are not changed. Therefore, the horizontal width of the housing 11 does not change even if the area of the supply air outlet 142 is not reduced. Therefore, the heat exchanger can ensure the smoothness of the air passage, ensure the air volume and ensure the heat exchange efficiency.
In addition, in general, the size of the components provided in the air supply air passage 12 is different from the size of the components provided in the exhaust air passage 13, and the dust collecting unit provided in the air supply air passage 12 is larger than the width of the exhaust fan 18 provided in the exhaust air passage 13 in this embodiment. If four sides of the abutting surface 149 of the heat exchange unit 14 are equal and the side length of the abutting surface 149 is equal to the width of the dust collecting unit in the air supply passage 12, the side length of the abutting surface 149 opposite to the exhaust fan 18 in the exhaust air passage 13 is longer than the width of the exhaust fan 18. Similarly, when the four sides of the abutting surface 149 are equal and the side length of the abutting surface 149 is equal to the width of the exhaust fan 18 in the exhaust air passage 13, the side length of the abutting surface 149 facing the dust collection unit is shorter than the width of the dust collection unit. Thus, the air duct is not beneficial to ensuring the smoothness of the air duct, the space cannot be reasonably utilized, and the miniaturization of the whole machine is not beneficial.
In reverse of this embodiment, the abutment surface 149 comprises a set of long sides and a set of short sides, i.e., the four sides are not equally long. Therefore, in the heat exchange unit 14, the surface including the long side is larger in area than the surface including the short side except for the abutting surface 149. That is, the air supply exhaust port 142 and the air supply inlet port 141 are larger in area than the air discharge inlet port 143 and the air discharge inlet port, or the air discharge inlet port 143 and the air discharge inlet port are larger in area than the air supply exhaust port 142 and the air supply inlet port 141. As shown in fig. 5, when the dust collection unit 15 provided in the air supply passage 12 is wider than the exhaust fan 18 provided in the exhaust air passage 13, the heat exchange unit 14 may be configured such that a surface including the long sides of the abutting surface 149 in addition to the abutting surface 149 is provided in the air supply passage 12 in accordance with the widths of the dust collection unit 15 and the exhaust fan 18, and the surface including the long sides of the abutting surface 149 is used as the air supply inlet port 141 and the air supply outlet port 142; the surfaces including the short sides of the abutting surfaces 149 are provided in the exhaust air passage 13, that is, the surfaces including the short sides of the abutting surfaces 149 are the exhaust air inlet 143 and the exhaust air outlet 144. Therefore, the space in the shell 11 is more reasonably utilized, and the miniaturization of the whole machine is more favorably realized.
When the air inlet for air supply is not disposed obliquely as in the related art, but disposed horizontally with respect to the bottom surface of the casing, the air blower 17, the air path switching plate 161, and other components need to be disposed below the heat exchange unit 14, so that the height of the casing is increased, which is not advantageous for the miniaturization of the entire machine.
In contrast to the present embodiment, one of the surfaces adjacent to the abutting surface 149 is parallel to the side wall perpendicular to the bottom surface 115 of the housing 11, and the non-abutting surface 149 adjacent to the one surface is disposed in the housing 11 to be inclined with respect to the side wall. That is, for example, when the exhaust air inlet 143 and the exhaust air outlet 144 are parallel to the side wall of the casing 11, the supply air inlet 141 and the supply air outlet 142 are provided in the casing 11 obliquely with respect to the side wall. That is, when the exhaust air inlet 143 and the exhaust air outlet 144 are parallel to the left side surface 118 and the right side surface 119 of the casing 11, the supply air inlet 141 and the supply air outlet 142 are provided in the casing 11 so as to be inclined with respect to the left side surface 118 and the right side surface 119 of the casing 11. When the air supply inlet port 141 and the air supply outlet port 142 are obliquely disposed, the surface of the air supply inlet port 141 intersects with the bottom surface 115 and the right side surface 119 of the housing 11, a housing space (similar to a triangular body) is formed on one side of the bottom surface 115 of the housing 11, and when a component (such as the air supply fan 17, the air path switching plate 161, and the like) is disposed in the housing space, a part of the component overlaps with the heat exchange unit 14 in the height of the housing 11 (the direction perpendicular to the bottom surface 115 of the housing 11). Thereby realizing the miniaturization of the whole machine.
In this embodiment, the top surface, the bottom surface, and the side surface of the housing 11 are all relative concepts. When viewed in the perspective of fig. 3, one of the faces abutting the abutment face 149 is parallel to the side wall perpendicular to the bottom face 115 of the housing 11. If the heat exchange device 10 is rotated 90 degrees, the left side surface 118 or the right side surface 119 in fig. 3 becomes a bottom surface, and at this time, one of the surfaces adjacent to the abutting surface 149 is parallel to the bottom surface of the housing 11.
Further, when the exhaust air inlet 143 is parallel to the exhaust air inlet 111, the space inside the housing 11 is effectively used, and the air entering from the exhaust air inlet 111 can directly enter the heat exchange unit 14 through the exhaust air inlet 143, so that the pressure loss is not increased due to complication, and the air passage is ensured to be smooth.
In the present embodiment, as shown in fig. 5, the air supply outlet 142 is provided in the housing 11 so as to be inclined with respect to the bottom surface 115 of the housing 11, and the dust collection unit 15 is provided so as to face the air supply outlet 142. That is, the dust collecting unit 15 disposed on the downstream side of the air supply outlet is also disposed in the housing 11 obliquely with respect to the bottom surface 115 of the housing 11, that is, the air inlet surface 151 and the air outlet surface 152 of the dust collecting unit 15 are parallel to the air supply outlet 142 and are disposed obliquely with respect to the bottom surface 115 of the housing 11. In the mounted state of the heat exchange device 10, the dust collection unit 15 disposed in an inclined state on the downstream side of the heat exchange unit 14 is partially or entirely overlapped with the heat exchange unit 14 in the up-down direction. The up-down direction refers to a direction perpendicular to the bottom surface 115 of the housing 11. When the dust collecting unit 15 and the heat exchanging unit 14 are only partially overlapped, the exhaust fan 18 is disposed below the dust collecting unit 15 and at a position not overlapped with the heat exchanging unit 14, so that the space utilization rate in the housing 11 can be improved, and the miniaturization of the whole machine can be realized.
Further, when the air inlet surface 151 of the dust collection unit 15 is parallel to and opposite to the air supply outlet 142, the length of the long side of the air inlet surface 151 of the dust collection unit 15 can be set to be equal to the length of the long side of the air supply outlet 142, so that not only the filtering efficiency of the dust collection unit 15 can be ensured, but also the distance between the heat exchange unit 14 and the dust collection unit 15 can be shortened, thereby realizing the miniaturization of the whole machine.
The structure and effects of the present embodiment have been described above mainly in embodiment 1, in which the angle between the surface on which the exhaust air inlet 143 is located and the surface on which the supply air outlet 142 is located is an acute angle a, and the angle between the surface on which the exhaust air outlet 144 is located and the surface on which the supply air inlet 141 is located is an acute angle a. Embodiment 2 is similar to embodiment 1 in structure and effect, in that the angle between the surface of the exhaust air inlet 143 and the surface of the supply air inlet 141 is an acute angle a, and the angle between the surface of the exhaust air outlet 144 and the surface of the supply air outlet 142 is an acute angle a. For example, when embodiment 2 is employed, the exhaust fan 18 is placed on the right side of the heat exchange unit 14, i.e., on the downstream side of the exhaust outlet 144 of the heat exchange unit 14, in the perspective of fig. 3 and 5. The exhaust air inlet 113 is disposed on the left side 118 of the housing 11. The exhaust air inlet 143 is provided on a left surface 147 of the heat exchange unit 14, and the exhaust air outlet 144 is provided on a right surface 148 of the heat exchange unit 14. The above-described technical effects can be similarly achieved by forming the housing space on the bottom surface 115 of the housing 11 such that the surface where the air inlet 141 is located intersects the bottom surface 115 and the left side surface 118 of the housing 11.
