Description

Technical Field

[0001] The utility model relates to the technical field of clothes drying equipment, in particular to a clothes dryer. Background Art

[0002] As an indispensable appliance in modern households, the main function of a clothes dryer is to use hot air to quickly dry wet clothes. However, existing clothes dryers generally have some significant design deficiencies. First, many clothes dryers are large in size and lack the characteristics of being compact and portable. When not in use, it is difficult to find a suitable place to put them in a home or apartment with limited space, resulting in a waste of space and limited use. At the same time, for users who need to move or store dryers frequently, the heavier and larger dryers greatly reduce their portability. Secondly, the management and circulation of hot air are key factors affecting the drying efficiency of the dryer. During the operation of existing clothes dryers, due to unreasonable design, hot air is easily lost during the circulation process and fails to be effectively maintained in the drying chamber. This heat loss not only reduces the working efficiency of the dryer, but also leads to longer heating time, increased energy consumption, and affects the overall user experience.

The area of ​​the screw hole 24 is equal to the area of ​​the mounting hole 22. The dryer body 1 and the fixed shaft 5 are bolted together through the mounting hole 22 and the screw hole 24. A limiting disc 25 is provided at the end of the fixed shaft 5 away from the rotation limiting assembly 4 for limiting the first support rod 6 and the second support rod 7. The head end of the first support rod 6 close to the fixed shaft 5 is semicircular, and a limiting circular groove 26 is axially opened at the head end of the first support rod 6.

[0037] like Figure 8 、 9As shown, in addition to the above features, this embodiment further defines: the pushing and limiting assembly 8 is arranged on the inner side wall of the first support rod 6 near the limiting circular groove 26, the pushing and limiting assembly 8 includes a shell 32, and the shell 32 is internally provided with a top column 33, a first baffle 34, a second baffle 35 and a spring 36, one end of the top column 33 is hemispherical and protrudes from the shell 32 and is inserted into the limiting circular groove 26, the top column 33 passes through the first baffle 34 and the second baffle 35, and is fixedly connected to the first baffle 34, and movably connected to the second baffle 35, the first baffle 34 abuts against the inner wall of the shell 32, the second baffle 35 is fixedly connected to the shell 32, and the spring 36 is arranged on the outer ring of the top column 33 between the first baffle 34 and the second baffle 35. The first end of the second support rod 7 is provided with an arc-shaped slot 38. The outward side wall of the arc-shaped slot 38 is provided with a first engaging slot 39 and a second engaging slot 40. The top post 33 is engaged in the first engaging slot 39 or the second engaging slot 40. By pushing the first support rod 6, the top post 33 slides from the first engaging slot 39 to the second engaging slot 40, thereby achieving rotational limitation between the first support rod 6 and the second support rod 7.

[0038] Working principle:

[0039] The first support rod 6 and the second support rod 7 are first retracted to the back of the dryer body 1 and are parallel to the dryer body 1. This is the initial state. Figure 2 As shown;

[0040] When the clothes dryer needs to be started, the first support rod 6 is pushed clockwise. At this time, the first limit block 31 in the first support rod 6 is unrestricted and slides to the middle of the first arc-shaped limit plate 17 and the second arc-shaped limit plate 18, while the second limit block 41 in the second support rod 7 is unrestricted. Driven by the top column 33, the connection between the top column 33 and the first slot 39 is maintained. The second limit block 41 is driven to slide to abut against the first arc-shaped limit plate 17, and the groove 30 in the elastic ring 29 also rotates from the protrusion 16 of the first group of spring pieces 15 along the rotation direction of the first support rod 6, so that the protrusion 16 and the groove 30 are not matched. The protrusion 16 is squeezed by the elastic ring 29 and retracts toward the spring piece 15, and then enters the intermediate state. Figure 11 As shown;

[0041] Then continue to push the first support rod 6 clockwise. At this time, the second limit block 41 in the second support rod 7 is held against the first arc-shaped limit plate 17 and does not move, and the top column 33 in the first support rod 6 slides along the arc-shaped slide groove 38 from the first clamping groove 39 to the second clamping groove 40. With the support force of the second support rod 7, the first limit block 31 continues to slide without restriction until it abuts against the second arc-shaped limit plate 18. The groove 30 in the elastic ring 29 also rotates along the rotation direction of the first support rod 6 until it is engaged with the protrusion 16. At this time, it enters the expanded state, as shown in FIG. Figure 3 As shown, due to the limiting effect of the first arc-shaped limiting plate 17 and the second arc-shaped limiting plate 18, the first support rod 6 and the second support rod 7 can be stably maintained in the extended state. At this time, the clothes dryer can be used. Clothes are hung on the extended first support rod 6 and the second support rod 7, and the hot air blower 11 is started from the control panel 9. Hot air is blown from the air outlet 2 at the bottom into the clothes to dry the clothes.

[0042] After use, when the clothes dryer needs to be restored to its original state, the hot air blower 11 is turned off through the control panel 9, and the first support rod 6 is pushed counterclockwise. At this time, the first support rod 6 and the second support rod 7 are not restricted. According to the above principle, the first support rod 6 drives the second support rod 7 to restore the second support rod 7 to its initial state, and the first support rod 6 is first restored to the middle state, and then the second support rod 7 is restricted by the contact between the second support rod 7 and the second arc-shaped limit plate 18, and the first support rod 6 is continued to be pushed counterclockwise to completely restore the initial state. Figure 2 As shown, the clothes dryer is recycled as a whole, making the clothes dryer portable.

[0043] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
