In connection with the embodiment shown in fig. 2 and 3, the hot blast housing structure 100 of the dryer includes: the first cover body 4 and the second cover body 5, wherein, the first cover body 4 can play the effect of wind-guiding, and the first cover body 4 can change the direction of the high temperature air current that gets into in the hot air cover structure 100 from air intake 1 department, makes high temperature air current flow to air outlet 3 direction after contacting first cover body 4, and the rethread air outlet 3 flows outside the hot air cover structure 100.
Further, the second cover 5 covers one side of the first cover 4, and an air duct 2 is defined between the second cover 5 and the first cover 4, so as to form a complete air duct 2 between the first cover 4 and the second cover 5. The air inlet 1 is disposed in the second cover 5, and an air outlet 3 is defined between the edge of the second cover 5 and the edge of the first cover 4. That is, the air inlet 1 is formed at one side of the second cover 5 in the first direction, and the air outlet 3 is defined by the other side edge of the second cover 5 in the first direction and the other side edge of the first cover 4 in the first direction.
And the air inlet 1 and the air outlet 3 are arranged on the same side of the second cover body 5, so that the clothes dryer is conveniently arranged, and the whole structure of the clothes dryer is more compact.
As shown in fig. 1 and 2, the projection of the first cover 4 in a plane parallel to the first direction and the second direction has a first edge 41, a second edge 42 and two third edges 43, and two ends of the first edge 41 and two ends of the second edge 42 are respectively connected in a one-to-one correspondence manner through the two third edges 43 to form an edge profile of the first cover 4.
Wherein the first edge 41 and the second edge 42 form a circular arc shape, the third edge 43 forms a straight line shape, and the third edge 43 is tangent to the first edge 41 and the second edge 42 respectively. Therefore, no worm-shaped structure which can cause turbulence in the air duct 2 or other structures which influence wind resistance in the air duct 2 exists on the first cover body 4, so that the wind resistance in the air duct 2 is smaller, the air quantity circulation effect in the clothes treatment cavity of the clothes dryer is better, and the clothes drying effect of the clothes dryer is better.
Further, the projection of the second cover 5 in a plane parallel to the first direction and the second direction has a fourth edge 51, a fifth edge 52 and two sixth edges 53, and two ends of the fourth edge 51 and two ends of the fifth edge 52 are respectively connected in one-to-one correspondence through the two sixth edges 53 to form an edge profile of the second cover 5.

Still further, the fourth edge 51 has the same shape as the first edge 41 and is disposed corresponding to each other so that the fourth edge 51 and the first edge 41 can be engaged with each other. The circular arcs formed by the fifth edge 52 and the second edge 42 are two circular arcs which are complementary to each other, and the fifth edge 52 and the second edge 42 define the air outlet 3, and the sixth edge 53 and the third edge 43 have the same shape and are correspondingly arranged, so that the first cover 4 and the second cover 5 can be mutually buckled.
Since the temperature of the high-temperature air flow entering the hot air hood structure 100 at the air inlet 1 is higher, and the distance between the air inlet 1 and the air outlet 3 is shorter, the temperature of the air flow entering the clothes treatment cavity of the clothes dryer from the air outlet 3 is also higher, so that the high-temperature air flow can damage the clothes with fragile materials in the clothes treatment cavity, and the performance of the clothes dryer is affected.
In order to reduce the temperature of the air flowing out from the air outlet 3, the hot air cover structure 100 is further provided with a low-temperature air inlet 6, as shown in fig. 2 and 3, the low-temperature air inlet 6 is communicated with the air duct 2, so that the low-temperature air inlet 6 communicates the low-temperature air outside the air duct 2 with the high-temperature air in the air duct 2, and the low-temperature air and the high-temperature air in the air duct 2 can be mixed in the air duct 2 and then enter the clothes treatment cavity through the air outlet 3, thereby properly reducing the temperature of the air flowing into the clothes treatment cavity through the air outlet 3, and being beneficial to protecting the clothes with fragile materials.
Referring to fig. 1, a projection of the low temperature air inlet 6 in a plane parallel to the first and second directions is located between the air inlet 1 and the air outlet 3, so as to prevent high temperature air flowing from the air inlet 1 into the air duct 2 from directly flowing out through the low temperature air inlet 6 when the low temperature air inlet 6 is disposed near the air inlet 1, thereby preventing air loss at the low temperature air inlet 6, and preventing more low temperature air from entering at the low temperature air inlet 6 when the low temperature air inlet 6 is disposed near the air outlet 3, so that air flow temperature of the air outlet 3 entering the clothes treatment cavity is too low, and performance of the clothes dryer is affected.
Further, the low-temperature air inlet 6 is arranged at the position between the air inlet 1 and the air outlet 3, so that the low-temperature air entering from the low-temperature air inlet 6 and the high-temperature air entering from the air inlet 1 are uniformly mixed and then enter the clothes treatment cavity through the air outlet 3, the temperature of the air entering the clothes treatment cavity is uniform, and the clothes can be protected and dried.
In connection with the embodiment shown in fig. 2 and 3, the low temperature air inlet 6 is provided on the opposite side wall of the hot blast housing structure 100 from the air inlet 1 and the air outlet 3, so as to avoid that the high temperature on the side of the air inlet 1 and the air outlet 3 affects the temperature of the air entering from the low temperature air inlet 6, so that the temperature of the air entering from the low temperature air inlet 6 into the hot blast housing structure 100 is low enough to facilitate the low temperature air entering into the hot blast housing structure 100 through the low temperature air inlet 6.
And, because do not set up structures such as air intake 1 or air outlet 3 on the relative lateral wall of air intake 1 and air outlet 3, therefore it has better structural strength for the lateral wall with air intake 1 and air outlet 3 same side, consequently, set up low temperature air inlet 6 on air intake 1 and air outlet 3 relative lateral wall be favorable to improving hot air cover structure 100's bulk strength, improved hot air cover structure 100 overall arrangement's stability.

The distance between two adjacent low-temperature air inlets 6 is larger than 20mm, so that the strength of the hot air cover structure 100 is prevented from being influenced by the arrangement of the low-temperature air inlets 6.
In addition, each low-temperature air inlet 6 extends along the first direction, and because the flow direction of the high-temperature air flow in the air duct 2 also flows along the first direction, the length of the low-temperature air inlet 6 extends along the first direction, so that the low-temperature air and the air with higher temperature in the hot air cover structure 100 can be fully mixed, the air inlet quantity of the low-temperature air in unit time can be increased, the air flow temperature entering the clothes treatment cavity through the air outlet 3 can be effectively reduced, and the clothes with weaker materials can be protected.
Referring to fig. 2 and 3, since there is a large air pressure difference between the hot air hood structure 100 and the air outlet 3, a plurality of reinforcing ribs 7 are disposed on the wall surface of the hot air hood structure 100 opposite to the air outlet 3, so as to reinforce the wall surface of the air outlet 3 opposite to the reinforcing ribs 7, avoid deformation of the wall surface under the action of air pressure, and improve the overall stability of the hot air hood structure 100. Wherein, a plurality of strengthening ribs 7 are radial arrangement to avoid the setting of strengthening rib 7 to influence the windage in the hot-blast cover structure 100.
And because the intensity of low temperature air inlet 6 department is lower, therefore, a plurality of strengthening ribs 7 wherein be close to wind channel 2's one strengthening rib 7 extends to low temperature air inlet 6 department to strengthen low temperature air inlet 6 department, avoid low temperature air inlet 6 department to produce the deformation, improve the reliability of hot blast housing structure 100 overall structure.
