A clothes dryer with foldable support legs

Abstract

This utility model relates to the field of clothes dryer technology, and in particular to a clothes dryer with foldable support feet. It includes a main drying unit with a foldable support foot mechanism, which comprises support feet, a swing base, a swing shaft, and a driving elastic element. The support feet are rotatably mounted on the swing base via a rotating connection. The outer shell of the main drying unit has a clearance opening allowing the rotating connection to pass through. The section of the rotating connection located within the clearance opening is a locking section, which has a limiting protrusion. When the rotating connection is at its initial angle, the limiting protrusion prevents the locking section in the large opening from entering the transverse groove. When the rotating connection rotates to the unlocking angle, the limiting protrusion rotates away from the blocking position, allowing the locking section to enter the transverse groove, thus opening the support feet into an outward V-shape. The beneficial effect is that the support feet, when opened, can stably support the main drying unit, improving the stability and safety of the entire machine.

Description

Technical Field

[0001] This utility model relates to the field of clothes dryer technology, and in particular to a clothes dryer with foldable support legs. Background Technology

[0002] A clothes dryer is a device used to dry clothes. It can effectively solve the problem of clothes being unable to dry when there are no drying facilities. It can be used in homes, hotels and other places. In particular, since most hotels do not have independent drying spaces, portable clothes dryers are especially useful for people who travel frequently.

[0003] Clothes dryers are generally divided into upright dryers and wall dryers. Upright dryers can be used anywhere as long as the power cord is long enough to reach the socket, while wall dryers need to be hung on a horizontal bar, hooks or other hanging parts, and are limited by the hanging conditions when using them.

[0004] An upright dryer includes a main dryer, a clothes rack, and a hot air cover. The clothes rack is mounted on the main dryer, and the hot air cover is placed on the main dryer through its lower end. The clothes rack is located inside the hot air cover. The main dryer has at least one upward-facing hot air outlet for blowing hot air into the hot air cover to dry the clothes hanging on the clothes rack.

[0005] The existing problems with upright clothes dryers are: In order to ensure a compact size, the supporting legs of the portable upright clothes dryers are designed to be foldable. However, the supporting legs are few and short, resulting in insufficient support stability. This means that the clothes dryer cannot hang too many clothes, and the clothes rack cannot be too high to avoid the whole machine tipping over due to an excessively high center of gravity. Utility Model Content

[0006] The technical problem to be solved by this utility model is that the portable upright clothes dryer has a foldable support foot design to ensure a compact size, but the support foot is few and short, resulting in insufficient support stability.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a clothes dryer with foldable support feet, including a clothes dryer main unit, and a pair of foldable support foot mechanisms symmetrically arranged front and back on the left and right sides of the clothes dryer main unit. Each foldable support foot mechanism includes a support foot, a swing seat, a swing shaft and a driving elastic element.

[0008] The swing base is oscillatingly mounted on the bottom of the dryer and located inside the dryer via a swing shaft. The lower end of the support leg has a rotating connection. The outer casing of the dryer has a clearance opening that allows the rotating connection to pass through. The support leg is rotatably mounted on the swing base via the rotating connection. The clearance opening consists of a large through hole and a transverse groove. The section of the rotating connection located within the clearance opening is the locking section. The locking section of the rotating connection has a limiting protrusion. When the rotating connection is at the initial angle, the limiting protrusion prevents the locking section in the large through hole from entering the transverse groove. When the rotating connection rotates to the unlocking angle, the limiting protrusion rotates away from the blocking position, allowing the locking section to enter the transverse groove.

[0009] When the support leg is in the folded state, the rotating connection part is at the initial angle, the locking section is located in the large hole, and the support leg rests vertically against the side of the dryer.

[0010] The two support legs on the front of the dryer are opened by rotating forward, and the two support legs on the rear of the dryer are opened by rotating backward. When the support legs are opened to the correct position, the rotating connecting part also rotates to the unlocking angle. The swing seat swings inward under the elastic drive of the driving elastic element, which in turn drives the rotating connecting part to enter and swing laterally to the end of the transverse groove, so that the two support legs on the front and the two support legs on the rear are opened in an outward V-shape.

[0011] When the rotating connection is at the end of the transverse groove, the locking section of the rotating connection engages with the rotation limit of the transverse groove to lock the support foot.

[0012] In some embodiments, the locking section and the transverse groove are optionally rotated and limited by contact surfaces located on the upper and / or lower sides of the transverse groove to lock the support foot; or, the locking section and the transverse groove are rotated and limited by a locking structure with a convex-concave fit located on one side of the end face of the transverse groove to lock the support foot.

[0013] In some embodiments, the locking section may have a rectangular cross-sectional shape, a T-shaped clearance opening, and two ends of the short side of the locking section as limiting protrusions. The two sides of the long side of the locking section may contact and engage with the upper and lower sides of the transverse groove to perform rotational limiting and lock the support foot.

[0014] In some embodiments, the support foot may be a retractable support foot.

[0015] In some embodiments, the driving elastic element is optionally a torsion spring, which is sleeved on the swing shaft, with its two ends abutting against the swing seat and the housing of the dryer, respectively.

[0016] In some embodiments, the rotating connection can be rotatably mounted on the swing seat in the following specific structure: the swing seat has a shaft hole for mounting the rotating connection, the rear part of the locking section of the rotating connection has a connecting shaft section for engaging with the shaft hole on the swing seat, and the connecting shaft section is inserted into the shaft hole and axially limited by a limiting member.

[0017] In some embodiments, optionally, the dryer is a cuboid, and the foldable support foot mechanism is located at the four corners of the dryer. Each corner has a groove for accommodating the support foot, and when the support foot is in the folded state, the support foot is embedded in the groove.

[0018] In some embodiments, the limiting element may optionally be a snap ring or a nut.

[0019] In some embodiments, optionally, the side of the large opening adjacent to the transverse groove of the clearance opening has a flat surface for contacting and engaging with the flat surface of the long side of the locking section when the support leg is in the folded state.

[0020] In some embodiments, optionally, the number of limiting protrusions on the locking section is two, and when the rotating connection is at the initial angle, the limiting protrusions are located on the upper and lower sides of the locking section.

[0021] Alternatively, the locking section may have one limiting protrusion, and when the rotating connecting part is at the initial angle, the locking section may have an inlet portion for embedding the transverse groove portion, which is used to rotate the rotating connecting part.

[0022] The beneficial effects of this utility model are: the support feet of this dryer can stably support the main dryer after being opened, improving the stability and safety of the whole machine.

[0023] Automatic limit locking is achieved through the cooperation of the rotating connecting part and the transverse groove part, which is simple in structure and easy to operate;

[0024] The drive elastic element provides continuous preload to ensure that the support legs automatically lock after opening into place;

[0025] When folded, the support legs are fully embedded in the grooves of the main dryer, resulting in a neat appearance and easy storage and transportation. Attached Figure Description

[0049] Example 1, such as Figures 1-13 As shown, a clothes dryer with foldable support feet includes a clothes dryer main unit 1. On each of the left and right sides of the clothes dryer main unit 1, there is a pair of foldable support foot mechanisms arranged symmetrically front to back. Each foldable support foot mechanism includes a support foot 2, a swing seat 3, a swing shaft 4, and a driving elastic element 5.

[0050] The swing base 3 is oscillatingly mounted on the bottom of the dryer 1 via the swing shaft 4 and located inside the dryer 1. The lower end of the support leg 2 has a rotating connection part 7. The outer casing of the dryer 1 has a clearance opening 6 that allows the rotating connection part 7 to pass through. The support leg 2 is rotatably mounted on the swing base 3 via the rotating connection part 7. The clearance opening 6 is composed of a large through hole 6-1 and a transverse groove 6-2. The section of the rotating connection part 7 located within the clearance opening 6 is a locking section 7-1. The locking section 7-1 has a limiting... When the rotating connecting part 7 is at the initial angle, the limiting protrusion 7-1-1 prevents the locking section 7-1 in the large hole 6-1 from entering the transverse groove 6-2. When the rotating connecting part 7 is rotated to the unlocking angle, the limiting protrusion 7-1-1 rotates away from the blocking position, allowing the locking section 7-1 to enter the transverse groove 6-2. When the support foot 2 is in the folded state, the rotating connecting part 7 is at the initial angle, the locking section 7-1 is located in the large hole 6-1, and the support foot 2 is vertically against the side of the dryer 1.

[0051] The two support legs 2 on the front side of the dryer 1 are opened by rotating forward, and the two support legs 2 on the rear side of the dryer 1 are opened by rotating backward. When the support legs 2 are opened to the position, the rotating connecting part 7 is also rotated to the unlocking angle. The swing seat 3 swings inward under the elastic drive of the driving elastic element 5, thereby driving the rotating connecting part 7 to enter and swing laterally to the end of the transverse groove 6-2, so that the two support legs 2 on the front side and the two support legs 2 on the rear side are opened in an outward V-shape.

[0052] When the rotating connecting part 7 is at the end of the transverse groove 6-2, the locking section 7-1 is rotated and limited to engage with the transverse groove 6-2 to lock the support foot 2. Specifically, the locking section 7-1 and the transverse groove 6-2 are rotated and limited by contact surfaces located on the upper and / or lower sides of the transverse groove 6-2 to lock the support foot 2.

[0053] There are two limiting protrusions 7-1-1 on the locking section 7-1. When the rotating connecting part 7 is at the initial angle, the limiting protrusions 7-1-1 are located on the upper and lower sides of the locking section 7-1, which are used to prevent the locking section 7-1 from entering the transverse groove 6-2 in both the upper and lower directions when the support leg 2 is in the folded state.

[0054] In this embodiment 1, the cross-sectional shape of the locking section 7-1 is rectangular, the clearance opening 6 is a T-shaped clearance opening, the two ends of the short side of the locking section 7-1 are limiting protrusions 7-1-1, and the two sides of the long side of the locking section 7-1 contact and cooperate with the upper and lower sides of the transverse groove 6-2 for rotational limiting.

[0055] Support leg 2 is a telescopic support leg that can be extended and retracted.

[0056] The driving elastic element 5 is a torsion spring, which is sleeved on the swing shaft 4. The two ends of the torsion spring abut against the swing seat 3 and the housing of the dryer 1, respectively.

[0057] The specific structure of the rotating connecting part 7 being rotatably mounted on the swing seat 3 is as follows: the swing seat 3 has a shaft hole for mounting the rotating connecting part 7, and the rear part of the locking section 7-1 of the rotating connecting part 7 has a connecting shaft section 7-2 for cooperating with the shaft hole on the swing seat 3. The connecting shaft section 7-2 is inserted into the shaft hole and is axially limited by the limiting member.

[0058] The main dryer 1 is a cuboid, and the foldable support leg mechanism is located at the four corners of the main dryer 1. Each corner has a groove 9 to accommodate the support leg 2. When the support leg 2 is in the folded state, the support leg 2 is embedded in the groove 9.

[0059] The limiting component is nut 8, and correspondingly, the connecting shaft section 7-2 has a thread that matches nut 8. Of course, the limiting component can also be a retaining ring, and correspondingly, the connecting shaft section 7-2 has a retaining groove that matches the retaining ring.

[0060] The side of the large hole 6-1 of the clearance opening 6 adjacent to the transverse groove 6-2 is a flat surface, which is used to contact and engage with the flat surface of the long side of the locking section 7-1 when the support leg 2 is in the folded state, thereby forming a rotational positioning of the rotating connecting part 7 and positioning the support leg 2 in the folded state. When it is necessary to open the support leg 2, the rotating connecting part 7 needs to overcome the elastic driving force of the driving elastic member 5 and swing outward to release the rotational positioning effect before rotating the support leg 2.

[0061] The support leg 2 is in a horizontal position when it is fully open. The horizontal groove 6-2 of the clearance opening 6 extends laterally, and the length of the horizontal groove 6-2 limits the swing angle of the support leg 2 when it is fully open.

[0062] The dryer with foldable support legs also includes a clothes drying rod 10 and a hot air cover 11. The clothes drying rod 10 is mounted on the dryer main unit 1, and the hot air cover 11 is covered on the dryer main unit 1 by its lower end. The clothes drying rod 10 is located inside the hot air cover 11. The dryer main unit 1 has at least one upward-facing hot air outlet 4-1 for blowing hot air into the hot air cover 11 to dry clothes.

[0063] The opening process of the foldable support foot of this dryer is as follows: Rotate the support foot 2 outwards in sequence. When the support foot 2 is opened to the full position, the swing seat 3 drives the support foot 2 to swing, so that the two front support feet 2 and the two rear support feet 2 are opened into an outward V-shape. It is best to stretch the support foot 2 to its maximum length.

[0064] The folding process of the foldable support foot of the dryer is as follows: retract the support foot to its shortest length, then turn the rotating connecting part 7 of the support foot 2 out of the horizontal groove part 6-2 to the large hole part 6-1 in sequence to release the rotation limit of the support foot 2, and then rotate the support foot 2 in the opposite direction to vertically upward, so that the support foot 2 rests vertically against the side of the dryer 1, thus completing the folding of the support foot 2.

[0065] Example 2 is basically the same as Example 1, except that: in order to facilitate the smooth entry of the locking section 7-1 of the rotating connecting part 7, a chamfer is made at the entrance of the transverse groove 6-2 to form a flared mouth, and the corners of the locking section 7-1 are rounded, such as... Figure 14 and 15 As shown.

[0066] Example 3 is basically the same as Example 1, except that the cross-sectional shape of the locking section 7-1 of the rotating connection 7 is as follows: Figure 16 and 17 As shown, the cross-sectional shape of the locking section 7-1 of the rotary connection 7 can be rectangular or other shapes.

[0067] Example 4 is basically the same as Example 1, except that the cross-sectional shape of the locking section 7-1 is as follows: Figure 18 and 19 As shown, when the rotating connecting part 7 is at the end of the transverse groove part 6-2, the locking section 7-1 and the transverse groove part 6-2 are rotated and limited by a locking structure with a convex-concave fit located on one side of the end face of the transverse groove part 6-2, thereby locking the support foot 2.

[0068] Example 5 is basically the same as Example 1, except that the cross-sectional shape of the locking section 7-1 is as follows: Figure 20 and 21 As shown, the locking section 7-1 has one limiting protrusion 7-1-1. When the rotating connecting part 7 is at the initial angle, the locking section 7-1 has an insert portion with an inlet portion for embedding the transverse groove 6-2, which is used to rotate and position the rotating connecting part 7, positioning the support leg 2 in the folded state. When it is necessary to open the support leg 2, the rotating connecting part 7 needs to overcome the elastic driving force of the driving elastic member 5 to swing outward, releasing the rotational positioning effect of the insert portion, and then rotate the support leg 2.
