Description

Technical Field

[0001] This utility model relates to a clothes dryer. Background Technology

[0002] Existing household dryers typically consist of a main unit casing, an internal drying unit, and fixed air inlets and outlets. To ensure sufficient airflow and drying efficiency, the casing needs to have a large air inlet on the top or side wall, which works in conjunction with the air outlet on the bottom or side wall. While this design meets ventilation requirements, it significantly increases the overall size of the machine, making it unsuitable for placement in space-constrained locations and increasing transportation and installation costs.

[0003] This problem is even more pronounced in the portable dryer market. To maintain unobstructed airflow, portable dryers also have fixed air inlets on the body. The casing structure needs to reserve a large space for airflow design, which further increases the overall size of the machine, occupies more storage space, and is exposed for a long time when not in use, making it easy for dust and odors to enter, affecting the cleanliness of the machine and the user experience, and making it inconvenient to carry. Utility Model Content

[0004] The purpose of this invention is to provide a dryer that reduces the overall size of the machine and allows for flexible opening and closing of the air inlet.

[0005] The purpose of this utility model is achieved as follows:

[0006] A clothes dryer includes a main unit, a drying device, a left compartment, a right compartment, and an air inlet. The left compartment and the right compartment are rotatably connected to the main unit, and the left compartment and the right compartment are brought together to form a box for storing clothes drying bags.

[0007] The top of the main unit is provided with an opening that connects to the inner cavity of the main unit, and a blocking part is provided around the opening of the main unit. The bottom of the main unit has an air outlet that connects to the inner cavity of the main unit, and the drying device is located in the inner cavity of the main unit.

[0008] The air inlet seat is an open and hollow air inlet seat with an air inlet on its side wall. The air inlet seat is provided with a backing part. The air inlet seat is movably installed in the inner cavity of the host unit. The air inlet seat extends out of / retracts into the inner cavity of the host unit along the opening direction.

[0009] The air inlet extends out of the main unit's inner cavity along the opening direction until the abutting part of the air inlet contacts the blocking part of the main unit. The main unit restricts the movement distance of the air inlet, while part or all of the air inlet is exposed outside the main unit's inner cavity.

[0010] By setting an air inlet seat that can extend or retract along the opening direction, the air inlet seat can be completely stored in the inner cavity of the main unit when the air inlet function is not in use, so that the air inlet is closed, thereby significantly reducing the overall size of the dryer and making it convenient to store and carry.

[0011] When the air inlet is extended, the air inlet protrudes outside the machine, ensuring sufficient airflow and efficient drying. When retracted, it blocks external air from entering, preventing dust and odors from entering the machine and keeping the machine cavity clean.

[0012] The blocking and abutting parts between the air inlet base and the main unit cooperate to limit the extension and retraction stroke of the air inlet base without the need for an additional locking mechanism, making the structure simple and reliable.

[0013] The left and right compartments can be rotated and folded, and with the retractable air inlet base, the whole machine can be freely switched between the two states of use and storage, which not only meets the needs of efficient drying, but also has portability.

[0014] The objective of this utility model can also be achieved by the following technical measures:

[0015] Furthermore, a hook is provided on the top of the air inlet seat.

[0016] By utilizing the automatic coordination of the hook and gravity, when the dryer is suspended in use, the main unit moves down and causes the air inlet seat to extend simultaneously. This eliminates the need for the user to manually pull out the air inlet seat, automatically opening the air inlet and greatly simplifying the operation process and improving ease of use.

[0017] After the air inlet is detached from the suspension hook, it can smoothly retract into the inner cavity of the main unit under its own gravity, automatically closing the air inlet. This prevents dust or odors from being introduced due to forgetting to close it, ensuring the cleanliness of the machine cavity and reducing maintenance burden.

[0018] The automatic telescopic hook mechanism design eliminates the need for additional locking or releasing buttons, resulting in a simple and reliable structure that reduces the failure rate and improves the long-term stability and safety of the entire machine.

[0019] Furthermore, the hook includes a hook body and a rod body, which are connected together.

[0020] Furthermore, the top of the air inlet seat has a rod receiving groove, the top of the main unit has a hook receiving groove, and the rod part is rotatably connected to the rod receiving groove.

[0021] The air inlet seat retracts into the inner cavity of the main unit. The rod body receiving groove and the hook body receiving groove are connected. When the hook is rotated, the rod body part is placed in the rod body receiving groove and the hook body part is placed in the hook body receiving groove.

[0022] When the hook is stored, the rod and hook are respectively embedded in the rod receiving slot and hook receiving slot, which realizes the complete concealment of the hook when the air inlet seat is retracted, reducing the overall size of the machine. This is not only aesthetically pleasing but also prevents accidental collision damage from the hook and avoids dust accumulation, thus improving the safety and cleanliness of the entire machine.

[0023] Furthermore, the top of the air inlet seat has a first rod receiving groove, the top of the main unit has a second rod receiving groove and a hook receiving groove, and the rod part is rotatably connected to the first rod receiving groove.

[0024] The air inlet seat retracts into the inner cavity of the main unit. The first rod receiving groove and the second rod receiving groove are connected to form a rod receiving groove. The rod receiving groove and the hook receiving groove are connected. When the hook is rotated, the rod part is placed in the rod receiving groove and the hook part is placed in the hook receiving groove.

[0025] When the hook is stored, the rod and hook are respectively embedded in the rod receiving slot and hook receiving slot, which realizes the complete concealment of the hook when the air inlet seat is retracted, reducing the overall size of the machine. This is not only aesthetically pleasing but also prevents accidental collision damage from the hook and avoids dust accumulation, thus improving the safety and cleanliness of the entire machine.

[0026] Furthermore, the bottom of the side wall of the air inlet seat is provided with an outward flange located around its bottom opening, and the outward flange forms the abutment part.

[0027] The outward flange can be formed by a single stamping or bending, which saves materials and processes, and ensures stable engagement between the abutment and the main unit blocking part. This ensures that the air inlet seat has limited stroke and accurate positioning during the extension and retraction process, thus improving structural strength and reliability.

[0028] Furthermore, the top of the main unit is provided with a recessed step around the opening. The air inlet includes a hollow base and a top cover. The air inlet is opened on the side wall of the hollow base. The size of the top cover is larger than the size of the hollow base. The top cover is set on the top of the hollow base. The edge of the top cover around the hollow base forms an outer extension. The hollow base is retracted into the inner cavity of the main unit. The outer extension abuts against the recessed step.

[0029] With the air intake retracted, a smooth transition is achieved between the top cover and the top of the main unit, which not only enhances the overall appearance but also effectively prevents dust or foreign objects from entering the cavity. At the same time, the combination of the recessed step and the outer edge provides additional mechanical positioning and sealing effects, further optimizing the structural compactness and airtightness.

[0030] Furthermore, it also includes a clothes rack, which is mounted on the main unit and located below the air outlet.

[0031] A clothes rack is installed on the main unit and positioned below the air outlet. The hot air generated by the dryer blows directly onto the clothes hanging on the rack, accelerating the drying process.

[0032] Furthermore, the drying device includes a fan and a heating element. The drying device is located below the opening. When the air inlet seat retracts into the inner cavity of the main unit through the opening, the drying device enters the inner cavity of the air inlet seat through the bottom opening of the air inlet seat.

[0033] Because the fan and heating element can pass through the bottom opening into the inner cavity of the air inlet when the air inlet is retracted, the drying device is effectively "folded" into the air inlet, thus making full use of the overlapping space between the air inlet and the main unit, significantly reducing the overall height and volume of the unit, making it easy to carry and store.

[0034] When the air inlet extends along the opening direction, the fan and heating element return to the bottom of the main unit's inner cavity, forming a connected airflow channel between the inner cavity of the air inlet and the inner cavity of the main unit. This channel structure allows cold air from outside the machine to smoothly enter the air duct through the air inlet, be accelerated by the fan, and be evenly heated by the heating element before being efficiently discharged from the air outlet, thus improving airflow speed and heat transfer efficiency, and thereby improving the overall drying effect.

[0035] Furthermore, it also includes a left toothed component and a right toothed component, the left toothed component being rotatably mounted on the main unit, the right toothed component being rotatably mounted on the main unit, the left toothed component and the right toothed component meshing, the left housing portion being connected to the left toothed component, and the right housing portion being connected to the right toothed component.

[0036] By setting left and right meshing gears on the main unit and connecting the left and right boxes to the corresponding gears respectively, when the user rotates either box, the other box can respond synchronously and move at a constant speed, ensuring the smooth and stable closing and unfolding process of the left and right boxes.

[0037] The synchronized design of the left and right compartments allows users to open or close them simultaneously with just one hand or a single point, improving ease of operation and efficiency.

[0038] Furthermore, it also includes a locking device, which includes a spring, a back plate, and a pressure plate. The back plate is disposed inside the main unit, and the left tooth component is rotatably disposed on the back plate, and the right tooth component is rotatably disposed on the back plate.

[0039] The spring sheet includes an elastic protrusion and an elastic extension;

[0040] The back plate has a left opening corresponding to the position of the left tooth component, the elastic protrusion extends out of the left opening, and the elastic extension abuts against the back plate;

[0041] The back plate has a right opening corresponding to the position of the right tooth component, the elastic protrusion extends out of the right opening, and the elastic extension abuts against the back plate;

[0042] The pressure plate is disposed on the back plate, and the pressure plate and the back plate together clamp the elastic extension portion;

[0043] The left tooth component has left retaining ribs spaced apart along its circumference on the end face near the back plate, and the right tooth component has right retaining ribs spaced apart along its circumference on the end face near the back plate.

[0044] When the left and right boxes are unfolded, the elastic protrusions abut against the corresponding left and right baffles respectively, locking the positions of the left and right boxes.

[0045] When the left and right box sections close together, the elastic protrusions abut against the corresponding left and right baffles, respectively, locking the positions of the left and right box sections.

[0046] When the left and right compartments are unfolded or closed, the spring tabs abut against the corresponding left and right retaining ribs to prevent the left and right compartments from loosening due to gravity when unfolded, and to prevent them from loosening when closed, thus improving safety. If the user needs to change the state of the left and right compartments, the user needs to apply a force that can overcome the spring tabs to push the left or right compartment, further improving the safety of the dryer.

[0047] The beneficial effects of this utility model are as follows:

[0048] This utility model allows the air inlet seat to automatically extend and position itself when the hook is suspended under load, opening the air inlet without manual pulling. After the hook is released, the air inlet seat can retract under its own weight and close precisely, greatly simplifying the use and storage process.

[0049] In this invention, after the air inlet extends, the inner cavity of the air inlet is integrated with the inner cavity of the main unit, allowing external air to smoothly enter the air duct, be drawn in by the fan, heated by the heating element, and then sprayed out from the air outlet. The hot air wraps around the clothes from bottom to top, achieving a faster and more uniform drying effect.

[0050] In this invention, the left and right boxes of the air inlet are linked by meshing gears. Whether unfolding or folding, it can be completed synchronously by operating only one side, avoiding uneven force on one side, jamming or wear, and improving structural durability and ease of operation.

[0051] In this invention, the top cover of the air inlet base fits snugly with the recessed step, and the air inlet base retracts into the inner cavity of the main unit, effectively blocking dust. The hook can be completely hidden inside the main unit, and the left and right boxes can be folded into a box, presenting a smooth and flat outline, saving storage space, and improving the overall appearance and portability of the machine.

[0087] The left tooth component 100 is provided with left baffles 101 at intervals along its circumference on the end face near the back plate 30, and the right tooth component 200 is provided with right baffles 300 at intervals along its circumference on the end face near the back plate 30.

[0088] When the left box section 3 and the right box section 4 are unfolded, the elastic protrusion 201 abuts against the corresponding left baffle 101 and right baffle 300 respectively, locking the positions of the left box section 3 and the right box section 4.

[0089] When the left box section 3 and the right box section 4 are closed together, the elastic protrusion 201 abuts against the corresponding left baffle 101 and right baffle 300 respectively, locking the positions of the left box section 3 and the right box section 4.

[0090] Working principle in suspended state

[0091] First, when the user hangs the dryer hook 6 on the crossbar, the main unit 1 moves down under the action of gravity, causing the air inlet seat 5 to extend out of the inner cavity of the main unit 1 along the direction of the opening 11 until its abutment part 52 is in close contact with the blocking part 12, completing the maximum stroke positioning. At this time, the air inlet 51 is completely exposed outside the inner cavity of the main unit 1, and the air intake function can be automatically turned on without any manual operation.

[0092] Next, the user rotates the left box 3 or the right box 4. The internal gear linkage ensures that the left box 3 and the right box 4 unfold synchronously and smoothly. When the left box 3 and the right box 4 are fully unfolded, the elastic protrusion 201 abuts against the corresponding left baffle 101 and right baffle 300 respectively, locking the position of the left box and the right box.

[0093] Users can connect the drying bag to the corresponding left compartment 3 and right compartment 4, with the clothes hanging rod 9 located inside the drying bag.

[0094] After the air inlet seat 5 extends, the inner cavity of the air inlet seat 5 and the inner cavity of the main unit 1 form an airflow channel. Outside air enters from the air inlet 51, is drawn in by the fan 21 and heated evenly by the heating element 22, and is then sprayed out from the bottom air outlet 13. The hot air wraps around the hanging clothes from bottom to top, accelerates the evaporation of moisture, and achieves efficient drying.

[0095] Working principle of storage state

[0096] First, after the dryer detaches from the hook 6, the air inlet seat 5 slides back into the inner cavity of the main unit 1 along the opening 11 under its own gravity. The fan 21 and the heating element 22 can enter the inner cavity of the air inlet seat 5 through its bottom opening when the air inlet seat 5 is retracted. The drying device is effectively "folded" into the inner cavity of the air inlet seat 5, thus making full use of the overlapping part between the air inlet seat 5 and the main unit 1, significantly reducing the overall height and volume of the machine, making it easy to carry and store. Until the air inlet 51 is completely closed, the outer edge 81 of the top cover 8 fits tightly with the recessed step 111 of the main unit, with a smooth transition on the surface, which is both beautiful and dustproof.

[0097] Next, the user rotates the hook 6 so that the rod body 62 is placed in the rod body receiving groove 53 and the hook body 61 is placed in the hook body receiving groove 14, thus completely hiding the hook 6.

[0098] Finally, the user folds the left compartment 3 and the right compartment 4. The gear linkage ensures synchronous closure. When the left and right compartments are fully closed, the elastic protrusions 201 abut against the corresponding left baffle 101 and right baffle 300 respectively, locking the positions of the left and right compartments. The whole machine presents a compact and flat storage form, which is convenient for carrying and storing.
