The support rod 21 is arranged along the circumferential outer side of the drying room 4, which means that the support rod 21 is located inside the drying room 4 and abuts against the outermost circle of the drying room 4.

[0036] The hot air device 1 comprises a shell 11, a heating element 13 and a fan 12 arranged on the shell 11. The shell 11 is provided with an air outlet 114, and the shell 11 forms an air outlet air duct 17 between the air outlet part 121 of the fan 12 and the air outlet 114.

[0041] Further, the frame 2 comprises a plurality of support rods 21 and cross rods 22, the plurality of support rods 21 extend along the first direction X and are arranged at intervals along the outer side of the circumference of the drying room 4. For example, the support rods 21 are provided in four, and the outer cover 3 is arranged outside the support rods 21 to form a top wall and four side wall bodies 31, which are sequentially connected along the outer circumference of the top wall; the side wall body 31 is an inner side wall towards the side of the drying room 4, and there are four inner side walls corresponding to the four side wall bodies 31. The region between the two support rods 21 corresponding to the adjacent circumferences is a wind receiving surface 32. In an embodiment, one side wall body 31 corresponds to one wind receiving surface 32. The drying room 4 is a rectangular chamber, and the outer cover 3 has four side wall bodies 31, which are enclosed into a circumferential wall body in the shape of a rectangle, each side wall body 31 corresponds to each wind receiving surface 32, and the support rods 21 are arranged at the connection between two adjacent side wall bodies 31. The top part between the support rods 21 is connected and fixed by the cross rods 22, which can be used for hanging clothes. The frame 2 further comprises a base frame 23, and the bottom part between the support rods 21 is connected by the base frame 23. The base frame 23 can be in the shape of a shell or a rod, and in the embodiment, the base frame 23 is in the shape of a rectangular shell, and the support rods 21 are connected at the four corner portions of the base frame 23, and the outer cover 3 and the base frame 23 enclose a space to form the drying room 4. In other embodiments, each side wall body 31 corresponds to three or more support rods 21, and each side wall body 31 corresponds to two or more wind receiving surfaces 32, which are not limited herein.

[0042] The hot air device 1 is arranged in the drying room 4 (e.g., on the base frame 23), and the hot air device 1 comprises a shell 11, a heating element 13 and a fan 12 arranged on the shell 11. The shell 11 is provided with an air outlet 114, and the shell 11 forms an air outlet air duct 17 between the air outlet portion 121 of the fan 12 and the air outlet 114. Specifically, the shell 11 has an accommodation cavity 113 inside, the heating element 13 and the fan 12 are arranged in the accommodation cavity 113, the air outlet air duct 17 is connected between the air outlet portion 121 of the fan 12 and the air outlet 114, the heating element 13 is arranged in the air outlet air duct 17, and the air blown by the fan 12 flows through the heating element 13 and is blown out from the air outlet 114.

[0043] Further, the air outlet 114 is provided with a guide wall 14 on each of the opposite sides in the horizontal direction, and the guide direction of each guide wall 14 is towards the air receiving surface 32. Specifically, the air outlet 114 is towards the circumferential outer side of the drying chamber 4, and the guide wall 14 extends from the end away from the support rod 21 to the end close to the support rod 21, and extends towards the center of the air outlet 114. For example, the air outlet 114 is along the second direction Y towards the air receiving surface 32 between two adjacent support rods 21, and towards the middle position of the air receiving surface 32, so that the hot air is blown towards the center position of the air receiving surface 32. The air outlet 114 has a length direction along the third direction Z, and the guide wall 14 is provided on each of the opposite ends of the air outlet 114 in the third direction Z. The guide wall 14 extends from the end away from the support rod 21 towards the center of the air outlet 114, and the height of the guide wall 14 in the first direction X is matched with the height of the air outlet 114, and the guide wall 14 is arranged at the end of the air outlet 114.

[0044] Since the hot air device 1 is arranged in the drying chamber 4, the support rod 21 is arranged at the connection of the two side wall bodies 31 along the circumferential outer side of the drying chamber 4, and the air receiving surface 32 is located between two circumferentially adjacent support rods 21. The length of the hot air device 1 in the third direction Z is less than or equal to the distance between the two support rods 21, and the length of the air outlet 114 in the third direction Z is also less than or equal to the distance between the two support rods 21. By arranging the guide wall 14 in the air outlet air duct 17 corresponding to the opposite ends of the air outlet 114 in the third direction Z, the guide direction of the guide wall 14 is towards the middle region of the air outlet 114 in the third direction Z, so as to guide the airflow to the middle position of the air outlet 114. The air outlet 114 is along the second direction Y towards the circumferentially adjacent two support rods 21, and under the action of the guide wall 14, the air is blown out from the air outlet 114 along the second direction Y and towards the middle position of the two support rods 21 in the third direction Z, so as to avoid the airflow directly blowing on the support rod 21 to cause excessively high temperature.

[0045] It should be noted that the first direction X, the second direction Y and the third direction Z are perpendicular to each other, and in this application, the first direction X is the vertical direction, which is also the height direction of the clothes dryer; the second direction Y is the length direction of the clothes dryer; and the third direction Z is the width direction of the clothes dryer, which will not be described below.

[0046] In an embodiment, with reference to Figures 5 to 7, the air outlet 114 of the hot air device 1 is in a strip shape, the air outlet 114 is provided with a plurality of gratings, the plurality of gratings are arranged at intervals in the air outlet 114 and separate the air outlet 114 into a plurality of sub-air outlets 1141, and the plurality of sub-air outlets 1141 are arranged at intervals along the third direction Z to form a high-speed concentrated airflow, while avoiding the clothes from entering the hot air device 1 from the air outlet 114. In the third direction Z, the first and last sub-air outlets 1141 are referred to as the ports 1142. The air guide walls 14 are arranged in the air outlet air duct 17, and the air guide walls 14 are opposite the ports 1142 at one end close to the air outlet 114. Specifically, the air guide wall 14 has a first end 141 away from one end of the air outlet 114 in the second direction Y, and a second end 142 close to one end of the air outlet 114, the air guide wall 14 extends from the first end 141 to the second end 142 along the center of the air outlet 114, and the second end 142 is opposite the port 1142. Since the air guide wall 14 is provided with two, the air guide wall 14 is provided with two, the two air guide walls 14 are located at opposite ends of the air outlet 114 in the third direction Z, and the air guide walls 14 at both ends are directed to the middle position of the air outlet 114 in the third direction Z; ensure that the hot air flows away from the support rod 21 at the end of the air outlet 114, reduce the influence of the hot air directly acting on the support rod 21.

[0047] In an embodiment, specifically as Figure 5 and Figure 7As shown, two air deflectors 18 are arranged between the two air deflectors 14, and each air deflector 18 is arranged in parallel with and spaced apart from the two air deflectors 14. Each air deflector 18 extends from an end away from the support rod 21 to an end close to the support rod 21, and extends towards the center of the air outlet 114. Specifically, the air deflector 18 has the same shape as the air deflector 14, and each air deflector 18 is arranged in parallel with and spaced apart from the air deflector 14 corresponding thereto. The two air deflectors 18 are arranged between the two air deflectors 14 corresponding thereto, and are arranged close to the opposite ends of the air outlet 114 in the third direction Z. The air deflectors 18 are arranged to increase the air deflection area, so that more air is gathered in the center of the air outlet 114, the air deflection efficiency is improved, the probability of hot air directly blowing to the support rod 21 is reduced, and the air outlet air speed can be further improved. For example, the air outlet 114 has two ports 1142 at the two ends, and the sub-air outlet 1141 adjacent to the port 1142 is referred to as a second sub-air outlet. Each air deflector 14 corresponds to an end port 1142, and each air deflector 18 corresponds to a second sub-air outlet. In other embodiments, the number of air deflectors 18 can be greater than two, which is not limited herein. The end 142 of the air deflector 14 can be connected with the wall body surrounding the sub-air outlet 1141, or arranged outside the sub-air outlet 1141. The projection of the end 142 of the air deflector 14 in the second direction Y falls within the sub-air outlet 1141, so as to ensure that the end 142 of the air deflector 14 is arranged corresponding to the sub-air outlet 1141. Similarly, the air deflector 18 also has a head corresponding to the head end 141 and a tail corresponding to the tail end 142. The connection structure and positional relationship of the head and the tail are the same as those of the head end 141 and the tail end 142, which will not be described herein.

[0048] Further, in the third direction Z, the air outlet 114 is arranged corresponding to the heating element 13, and the length of the air outlet 114 is greater than or equal to the length of the heating element 13. For example, in the first direction X, the air outlet 114 is located above the heating element 13, and the length of the heating element 13 in the third direction Z corresponds to the length of the air outlet 114 in the third direction Z. For example, in the third direction Z, the ends of the heating element 13 are aligned with the ends of the air outlet 114, or the projections of the ends of the heating element 13 in the direction opposite to the air outlet 114 fall within the air outlet 114, so as to ensure that the heat is quickly dissipated, and the heat is prevented from being gathered in the air outlet air duct 17.

[0049] In an embodiment, as shown in FIG. 1, Figure 3 and Figure 4As shown, the outer housing 11 comprises a bottom shell 111 and a cover 112. The bottom shell 111 is an open box, and the bottom shell 111 has a mounting cavity 1111 inside, and the heating element 13 and the fan 12 are arranged in the mounting cavity 1111. The top of the bottom shell 111 is provided with an opening communicating with the mounting cavity 1111, and the cover 112 is arranged at the opening, and the air outlet 114 is arranged on the cover 112. The fan 12 and the heating element can be disassembled through the opening, so that the installation is convenient. The cover 112 has a top surface 1121 and a side surface 1122 wall connected to the periphery of the top surface 1121, forming a cap shape, and the end of the side surface 1122 away from the top surface 1121 is connected to the bottom shell 111, and the air outlet 114 is arranged on the side surface 1122. The top surface 1121 is directed to the top of the drying room 4 along the first direction X, and the side surface 1122 is perpendicular to the top surface 1121 and is arranged around the periphery of the top surface 1121, forming an air outlet cavity; the air outlet duct 17 is mainly arranged in the air outlet cavity; the air outlet cavity and the mounting cavity 1111 are connected to form a containing cavity 113. The air outlet 114 is arranged on the side surface 1122, which ensures that the air blown by the fan 12 is discharged along the second direction Y. The cover 112 covers the opening of the bottom shell 111, and the top surface 1121 forms a shielding for the opening, and the air outlet 114 is arranged on the side surface 1122 instead of the conventional method of arranging the air outlet 114 on the top surface 1121, which avoids water droplets from falling along the direction of gravity and entering the inside of the outer housing 11 through the air outlet 114, and provides waterproof protection.

[0050] In one embodiment, as Figure 4 and Figure 5As shown, the heating element 13 is arranged above the fan 12 along the first direction X, and the air outlet portion 121 of the fan 12 is arranged towards the top surface 1121. The air guide 16 is arranged above the heating element 13 and located in the accommodating cavity 113. The air guide 16 is arranged spaced apart from the heating element 13 and completely covers the heating element 13 above to block the airflow passing through the heating element 13 from directly hitting the top surface 1121 of the cover 112, prevent high-temperature scalding, and reduce the risk of user scalding. Specifically, the air guide 16 is connected with the cover 112 and arranged spaced apart from the heating element 13 to avoid the heating element 13 from hot melting the air guide 16. After the airflow hits the air guide 16 along the first direction X, the airflow spreads around and flows to the air outlet 114 on the side surface 1122. The side edge of the air guide 16 is connected with the side surface 1122 of the cover 112 at a position above the air outlet 114 to avoid affecting the air outlet efficiency. The air guide wall 14 is arranged on the side of the air guide 16 close to the heating element 13 and extends towards the heating element 13 to form an air guide portion extending along the first direction X. The air guide portion extends along the second direction Y and close to the center of the air outlet 114 to make the air outlet direction of the air guide wall 14 towards the middle position of the air outlet 114 in the third direction Z. Further, the air guide 16 is provided with an inclined air guide surface 161 between the two air guide walls 14 to guide the airflow to the air outlet 114. For example, the air guide 16 is formed in a plate shape with an inclined arrangement. The side of the air guide 16 close to the heating element 13 is the air guide surface 161. The air guide surface 161 is arranged inclined downward from the end close to the air outlet 114 (top) to the end away from the air outlet 114. The bottom end of the air guide 16 is located above the heating element 13, so that part of the hot air tends to blow out of the top of the drying room 4. The hot air blows upwards to the wet clothes, and the drying effect is better. However, in order to prevent water, the air outlet 114 is arranged on the side surface 1122 of the cover 112. The hot air blows out of the side surface 1122 towards the second direction Y. Through the arrangement of the air guide 16, part of the hot air tends to blow out of the first direction X, which improves the drying effect of the clothes under the premise of reducing the influence of the hot air on the support rod 21.

[0051] Further, the hot air device 1 further comprises a frame 15 located in the accommodating cavity 113, for example, the frame 15 is located in the mounting cavity 1111 of the bottom shell 111, and the heating element 13 is arranged in the space enclosed by the frame 15. The air guide wall 14 is arranged in a spaced manner relative to the heating element 13 at one end (the bottom end) close to the heating element 13; the orthographic projection of the frame 15 in the second direction Y is connected with the orthographic projection of the air guide wall 14 in the second direction Y. Specifically, the top of the heating element 13 is flush with or lower than the top of the frame 15. If the top of the heating element 13 is flush with the top of the frame 15, the bottom end of the air guide wall 14 is connected with the heating element 13; if the top of the heating element 13 is lower than the top of the frame 15, the bottom of the heating element 13 extends to the top of the frame 15 or extends into the inside of the frame 15 in the first direction X, so as to ensure that the air flow passing through the opposite ends of the air outlet 114 is guided by the air guide wall 14, and the gap leakage is avoided. In an embodiment, the fan 12 and the heating element 13 are both arranged in the space enclosed by the frame 15, and the fan 12 is fixed to the side of the frame 15 away from the air outlet 114, so as to shorten the distance between the fan 12 and the heating element 13, reduce the wind power loss, and at the same time, the heating element 13 and the fan 12 can be fixed on the frame 15 in advance and then assembled in the mounting cavity 1111, so as to facilitate the assembly.

[0052] In an embodiment, as shown in Figure 5 and Figure 7 each air guide wall 14 is arc-shaped and recessed inwardly relative to the surface of the other air guide wall 14, the surface becomes an arc-shaped concave surface, and the arc-shaped concave surface faces the middle position of the heating element 13. Specifically, the air guide part of the air guide wall 14 is arc-shaped, so as to make the air flow smooth and reduce the turbulence. Moreover, the arc-shaped concave surface of the air guide part faces the middle position of the heating element 13, so as to ensure that the air guide wall 14 is inclined from the end away from the air outlet 114 to the middle position of the air outlet 114, and the two air guide walls 14 corresponding to the opposite ends of the air outlet 114 in the third direction Z are converged towards the middle position of the air outlet 114. Further, each air guide plate 18 is arc-shaped and recessed inwardly relative to the surface of the other air guide plate 18, the surface becomes an arc-shaped concave surface, and the arc-shaped concave surface faces the middle position of the heating element 13. The principle is the same as that of the air guide wall 14, and will not be described in more detail.

Specifically, the side surface 1122 of the cover body 112 is provided with an air outlet 114 on each of the opposite sides in the second direction Y, each air outlet 114 is arranged along the second direction Y towards the corresponding air receiving surface 32, and is arranged spaced apart from the corresponding air receiving surface 32, so that the hot air device 1 blows air to the opposite sides, respectively towards the two air receiving surfaces 32 in the second direction Y of the drying room 4, and the air flow is evenly distributed in the drying room 4, improving the drying effect. Further, the air guide member 16 is provided with two air guide walls 14 corresponding to each air outlet 114, and the air guide member 16 is provided with two air guide surfaces 161, the two air guide surfaces 161 are connected to each other to form a V shape on the side close to the heating element 13, and each air guide surface 161 is arranged corresponding to an air outlet 114. Specifically, the bottom of the air guide surface 161 is connected to each other along the second direction Y, the bottom of the air guide surface 161 forms the bottom of the air guide member 16, the bottom of the air guide member 16 is located at the middle position of the heating element 13 in the second direction Y, and each air guide member 16 is arranged inclined upward from the bottom towards the corresponding air outlet 114, so that the air flow flowing through the heating element 13 is inclined upward from the two air outlets 114 under the air guide of the air guide member 16. Further, each air outlet 114 is provided with two air guide walls 14, and each two air guide walls 14 are provided with an inclined air guide surface 161, and it can be understood that the V-shaped air guide member 16 has four air guide walls 14, and each two air guide walls 14 are arranged corresponding to an air guide surface 161 at the opposite ends in the third direction Z, simplifying the structure of the air guide wall 14.
