Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a quilt dryer. Background Art

[0002] A quilt dryer is a household appliance that provides hot air into the quilt. The existing quilt dryers mainly include a warm air device and a ventilation pipe connected to the warm air device. When in use, the hot air is sent into the quilt through the ventilation pipe to raise the temperature of the quilt. However, the above-mentioned quilt dryer has a small heat contact area and low heat transfer efficiency when in use.

[0003] In order to solve the above problems, a Chinese utility model patent with the publication number CN216845146U discloses a support for a quilt dryer. The support can be folded and unfolded. When in use, the quilt to be heated is supported by the support, and then the warm air device is placed at one end of the lower part of the support for the quilt dryer or the air outlet of the warm air device is placed at one end of the lower part of the support for the quilt dryer, thereby increasing the hot air contact surface between the quilt and the quilt dryer and increasing the heat transfer efficiency.

[0004] However, there are still problems such as troublesome operation when using the above-mentioned quilt dryer and support. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a quilt dryer, aiming to solve at least one of the defects of the above-mentioned prior art.

[0006] To achieve the above purpose, the utility model provides a quilt dryer, including: an air supply component, which includes a housing and an air supply device arranged in the housing;

[0007] Wherein, a first air inlet and a blowing port communicated with the air outlet of the air supply device are opened on the housing;

[0008] The air supply component further includes a base for arranging the housing. The base has a first axis, and the housing can rotate around the first axis.

[0009] Compared with the existing design, the present application provides the possibility for the quilt dryer to dry the quilt by setting an air supply device, a first air inlet opened on the housing, and a blowing port communicated with the air outlet of the air supply device. When the quilt dryer of the present application is placed in the quilt, the housing can rotate around the first axis of the base, so that the gas blown out by the quilt dryer also rotates along with the rotation direction of the housing, increasing the heat contact area, avoiding the concentration of hot air in one place, making the quilt drying more uniform and the drying effect better.

[0010] In some embodiments, the air supply component further includes: a second driving device and a transmission part drivingly connected to the second driving device;

[0011] The transmission part is arranged at the junction of the housing and the base.

[0012] By providing a second driving device which is connected to the transmission part, it makes it possible for the housing to rotate.

[0013] In some embodiments, the second driving device includes a second motor and a second transmission gear connected to the output shaft of the second motor;

[0014] The transmission part is a second tooth arranged circumferentially;

[0015] Wherein, the second motor is located inside the base, and the second transmission gear extends out of the base and meshes with the second tooth arranged circumferentially at the bottom of the housing;

[0016] Or the second motor is located inside the housing, and the second transmission gear extends out of the housing and meshes with the second tooth arranged circumferentially on the base.

[0017] By providing the second motor, the second transmission gear and the second tooth, when the second motor rotates, it drives the second tooth, which makes it possible for the second driving device to transmit power to the transmission part, thus enabling the housing to rotate.

[0018] In some embodiments, the air outlet is opened on the side of the housing.

[0019] By arranging the air outlet on the side of the housing, the gas blown out by the quilt dryer can blow to the middle of the supported quilt, increasing the heat contact area and achieving a better quilt drying effect.

[0020] In some embodiments, the quilt dryer further includes: a support assembly, which includes a lifting rod, the first end of the lifting rod penetrates into the housing, and the second end extends out of the housing; the support assembly further includes a support member connected to the second end of the lifting rod and a first driving device drivingly connected to the lifting rod; wherein, when the first driving device operates, it can drive the lifting rod to move up and down, so that the support member moves away from or close to the housing.

[0021] When the quilt dryer is placed in the quilt, the first driving device can drive the lifting rod to move up and down, so that the support member moves away from or close to the housing. When the support member moves away from the housing, the support member can support the quilt, and the quilt bulges to a certain height, further increasing the heat contact area, improving the heat transfer efficiency and achieving a good quilt drying effect; when the support member moves close to the housing, the quilt dryer is in a storage state. The user only needs to put the quilt dryer into the quilt to dry the quilt, and can directly take it out after the quilt is baked, eliminating the operation of manually unfolding or folding the quilt dryer to increase the heat contact area, making the quilt dryer convenient and fast to use.

[0022] In some embodiments, the first driving device includes a first motor and a first transmission gear connected to the output shaft of the first motor, and a first tooth mating with the first transmission gear is provided on the lifting rod.

[0023] By providing the first motor, the first transmission gear, and the first tooth on the lifting rod, when the first motor rotates, it drives the first tooth to move, which provides the possibility for the lifting rod to automatically rise or fall.

[0024] In some embodiments, the support assembly further includes a travel switch, which is arranged on the moving track of the lifting rod.

[0025] By arranging the travel switch on the moving track of the lifting rod, when the lifting rod rises or falls to a specified height, it triggers the travel switch, so that the lifting rod stops moving. The travel switch provides the possibility for the lifting rod to automatically stop rising and falling.

[0026] In some embodiments, the first air inlet is opened on the top surface of the housing; when the support member approaches the housing, the support member can cover the first air inlet.

[0027] By arranging the first air inlet on the top surface of the housing, when the support member is away from the housing, gas can enter through the first air inlet on the top surface of the housing, so that the gas at the top of the raised space of the quilt can also participate in the gas circulation, making the heat contact area larger and the quilt drying effect better. When the support member approaches the housing, the support member can cover the first air inlet, so that the first air inlet can be blocked. When the quilt dryer is not in use, it can prevent dust from entering through the first air inlet; and it makes the overall volume of the quilt dryer smaller, facilitating storage.

[0028] In some embodiments, the support member includes a top cover and side edges extending downward along the edge of the top cover, and a second air inlet is provided on the side edge.

[0029] By providing the second air inlet, when the lifting rod covers the first air inlet, air can also enter the support member through the second air inlet, and then the air enters the air supply device through the first air inlet. When the lifting rod drops to the lowest position, it provides the possibility for the quilt dryer to dry the quilt. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The technical solutions provided by the present utility model will be described in more detail below with reference to the accompanying drawings.

[0043] As Figure 1 shown, it is the quilt dryer of the embodiment of the present application.

[0044] As Figure 2 shown, specifically, the quilt dryer includes: an air supply assembly 1 and a support assembly 2.

[0045] Among them, the air supply assembly 1 is used to provide air for drying the quilt. The air supply assembly 1 includes: a housing 11, an air supply device 12, and a base 13. In this embodiment, the air supply device 12 is installed on the housing 11, and the housing 11 is installed on the base 13.

[0046] Specifically, the housing 11 is mounted on the base 13. The housing 11 is cylindrical, and is provided with a first air inlet 111 and an air blowing outlet 112 thereon. When the quilt dryer is placed in a quilt, the quilt bulges to a certain height to form a space. The gas in this space can enter the housing 11 through the first air inlet 111, and the gas is heated and accelerated by the air supply device 12, and finally blown out of the quilt dryer through the air blowing outlet 112. It should be understood that in other embodiments, the first air inlet 111 can also be arranged at other positions. For example, it can be arranged on both side surfaces of the housing 11 opposite to the air blowing outlet 112.

[0047] Specifically, the air supply device 12 can suck, heat and blow out gas, and is arranged in the housing 11. For example, the air supply device 12 includes a blower, a heating element, and an air outlet 121. The air blown out by the blower is heated by the heating element and finally blown out from the air outlet 121 and finally reaches the air blowing outlet 112 of the housing 11. In some embodiments, the air supply device 12 can also only blow air without heating the gas.

[0048] In order to make the heating effect of the quilt dryer better, the base 13 also has a first axis A, and the housing 11 can rotate around the first axis A, so that the direction of the gas blown out by the quilt dryer can rotate. For example, a shaft is arranged at the position of the central axes of the housing 11 and the base 13. The shaft is located on the first axis A and is supported by bearings, so that the housing 11 can rotate around the first axis A.

[0049] Compared with the existing design, when the quilt dryer of the present application is placed in a quilt, the housing 11 can rotate around the first axis A of the base 13, so that the gas blown out by the quilt dryer also rotates with the rotation direction of the housing 11, increasing the heat contact area, avoiding the hot air concentrating in one place, making the quilt drying more uniform and the quilt drying effect better.

[0050] As Figure 3 shown, preferably, in order to realize the rotation of the housing 11, the air supply assembly 1 includes: a second driving device 14 and a transmission part 15 drivingly connected to the second driving device 14. The transmission part 15 is arranged at the junction of the housing 11 and the base 13. By adopting a driving device and a transmission device, the housing 11 is driven to rotate.

[0051] Preferably, the second driving device 14 includes a second motor 141 and a second transmission gear 142 connected to the output shaft of the second motor; the transmission part 15 is a second tooth 151 arranged circumferentially.

[0052] Specifically, the second motor 141 is located within the base 13. The second transmission gear 142 extends out of the base 13 and meshes with the second teeth 151 circumferentially arranged at the bottom of the housing 11. For example, the second motor 141 is fixedly installed on the lower surface of the top surface of the base 13, and the second transmission gear 142 extends out of the top surface of the base 13; there is a circumferentially arranged ring of second teeth 151 at the bottom of the housing 11, and the second teeth 151 are racks; the second transmission gear 142 meshes with the second teeth 151. When the second motor 141 operates, the motor shaft rotates. Since the motor is fixed, the second teeth 151 rotate around the second transmission gear 142, thereby realizing the rotation of the housing 11. It should be understood that in other embodiments, the second motor 141 can also be located within the housing 11, and the second transmission gear 142 extends out of the housing 11 and meshes with the second teeth 151 circumferentially arranged on the base 13.

[0053] As Figure 2 , Figure 4 shown, wherein, the support assembly 2 is used to lift the quilt, and it includes: a lifting rod 21, a support member 22, and a first driving device 23. In this embodiment, the first driving device 23 is fixed on the housing 11. The first driving device 23 is connected to the lifting rod 21 and causes the lifting rod 21 to rise or fall, and further causes the support member 22 connected to the lifting rod 21 to rise or fall.

[0054] Specifically, the first end 211 of the lifting rod 21 passes through the housing 11, and the second end 212 extends out of the housing 11. For example, the lifting rod 21 is a straight rod with upper and lower ends. The first end 211 is the lower end, and the second end 212 is the upper end. The top of the housing 11 has a through hole. The lifting rod 21 passes through this through hole, so that the lower end of the lifting rod 21 vertically passes through the housing 11, and the upper end of the lifting rod 21 extends out of the top of the housing 11, and the lifting rod 21 can only move up and down along this through hole. It should be understood that in other embodiments, other methods can also be used to limit the lifting rod 21. For example, the housing 11 is provided with a limiting groove, and the lifting rod 21 is provided with a limiting post that cooperates with it. The limiting post moves in the limiting groove to cause the lifting rod 21 to rise or fall.

[0055] Specifically, the support member 22 is used to support the quilt and is connected to the second end 212 of the lifting rod 21. For example, the support member 22 is a hollow cap shape. The second end 212 of the lifting rod 21 passes through the hollow support member 22 and is connected to the top surface of the support member 22. The connection method between the lifting rod 21 and the support member 22 can be a fixed connection. For example, it is fixedly connected by a buckle; it can also be a movable connection. For example, the connection method is a ball joint. The support member 22 can move up and down with the lifting rod 21, but when the lifting rod 21 rotates, the support member 22 does not rotate together with the support member 22 to avoid the quilt from rotating. It should be understood that in other embodiments, the support member 22 can also be of other shapes. For example, the support member 22 is a flat plate or a conical shape.

[0056] Specifically, the first driving device 23 is drivingly connected to the lifting rod 21. For example, the driving manner of the first driving device 23 and the lifting rod 21 can be a worm and worm gear, or a rack and pinion drive.

[0057] Among them, when the first driving device 23 works, it can drive the lifting rod 21 to move up and down, so that the support member 22 moves away from or close to the housing 11. For example, when the worm of the first driving device 23 rotates, it drives the worm on the lifting rod 21 to move, so that the lifting rod 21 moves upward or downward, and then the support member 22 located on the lifting rod 21 moves away from or close to the housing 11. When the support member moves away from the housing, the support member can hold up the quilt, increasing the heat contact area and improving the heat transfer efficiency, and the quilt drying effect is good; when the support member moves close to the housing, the quilt dryer is retracted. The user only needs to put the quilt dryer into the quilt to dry the quilt, eliminating the operation of manually unfolding or folding the quilt dryer, making the quilt dryer convenient and fast to use.

[0058] As Figure 4 shown, preferably, the present application adopts a rack and pinion drive mode. Specifically, the first driving device 23 includes a first motor 231 and a first transmission gear 232 connected to the output shaft of the first motor 231. A first tooth 213 is provided on the lifting rod 21 and is engaged with the first transmission gear 232. For example, a fixing plate is vertically installed in the housing 11, the first motor 231 is installed on one side of the fixing plate, and the output shaft of the first motor 231 passes through the fixing plate and is arranged on the other side of the fixing plate. The output shaft of the first motor 231 is connected with the first transmission gear 232 by a key. The lifting rod 21 has a first tooth 213, and the first tooth 213 is a rack provided on the lifting rod 21. When the first motor 231 rotates forward, the output shaft of the first motor 231 drives the first transmission gear 232 to rotate, and the lifting rod 21 rises due to the engagement of the rack and the first transmission gear 232; when the first motor 231 rotates in reverse, the lifting rod 21 descends due to the engagement of the rack and the first transmission gear 232.

[0059] Preferably, the support assembly 2 further includes a travel switch 24, which is arranged on the moving track of the lifting rod 21. For example, in this embodiment, two travel switches 24, namely upper and lower travel switches, are arranged on the fixed plate, and the travel switch 24 is a microswitch; a cross bar extends radially from the second end 212 of the lifting rod 21. When the lifting rod 21 rises to the highest position, the cross bar triggers the first travel switch 24, causing the first motor 231 to cut off power and the lifting rod 21 to stop rising; when the lifting rod 21 descends to the lowest position, the cross bar triggers the second travel switch 24, causing the first motor 231 to cut off power and the lifting rod 21 to stop descending. It should be understood that in other embodiments, the travel switch 24 can also be set as two photoelectric switches. When the lifting rod 21 rises to the highest position, the first photoelectric switch is triggered and the lifting rod 21 stops rising; when the lifting rod 21 descends to the lowest position, the second photoelectric switch is triggered and the lifting rod 21 stops descending.

[0060] As Figure 5 shown, preferably, in order to enable more gas in the quilt to participate in heat contact, the first air inlet 111 is opened on the top surface of the housing 11. For example, in this embodiment, the area of the first air inlet 111 occupying the top surface of the housing 11 is greater than three - quarters, enabling the air supply device 12 to inhale sufficient gas, improving the gas flow rate of the quilt dryer, and further improving the heat conduction efficiency. Further, the shape of the first air inlet 111 is spiral, enabling the formation of an intake eddy current, accelerating the entry of gas into the air supply device 12, and further improving the heat transfer efficiency.

[0061] Preferably, when the support member 22 approaches the housing 11, the support member 22 can cover the first air inlet 111. For example, in this embodiment, the support member 22 is a hollow cylindrical shape without a bottom surface, enabling the support member 22 to cover the first air inlet 111. When the quilt dryer is not in use, the support member 22 covers the first air inlet 111, effectively preventing dust from entering the quilt dryer through the relatively large first air inlet 111. It should be understood that other support members 22 that can cover the first air inlet 111 are also allowed.

[0062] Further, in order for the quilt dryer to operate when the support member 22 completely covers the first air inlet 111, the support member 22 includes a top cover 221 and side edges 222 extending downward along the edge of the top cover 221, and the side edges 222 are provided with second air inlets 2221. For example, the second air inlets 2221 are long - strip - shaped grooves densely arranged on the side edges 222.

[0063] Preferably, the air outlet 112 is provided on the side surface of the housing 11. When the lifting rod 21 ascends, the support member 22 lifts up the quilt, and the gas is blown out through the air outlet 112, which can blow towards the lifted quilt, facilitating an increase in the heat contact area. It should be understood that in some other embodiments, the air outlet 112 can also be arranged below the base 13, and the first air inlet 111 is arranged at the top of the housing 11, further increasing the length of the air circulation path and making the heat conduction efficiency higher. It should be understood that in some other embodiments, the first air inlet 111 can also be arranged below the base 13, and the air outlet 112 is arranged at the top of the housing 11, enabling the cold air at a lower position to enter the quilt dryer, being heated and then blown out, further improving the heat conduction efficiency.

[0064] In this embodiment, as Figure 6 shown, when the user places the quilt dryer into the quilt, the lifting rod 21 can ascend, and the support member 22 lifts the quilt to a certain height; when the lifting rod 21 touches the travel switch 24, the lifting rod 21 stops ascending. At this time, the air supply device 12 blows air. When the air supply device 12 blows air, the second driving device 14 can also work synchronously, causing the housing 11 to rotate, so that the hot gas rotates and blows towards the quilt, and the quilt is fully baked.

[0065] As Figure 7 shown, when the quilt is baked well, the first driving device 23 works, and the lifting rod 21 descends. When the lifting rod 21 touches the travel switch 24, the lifting rod 21 stops descending, and the support member 22 covers the first air inlet 111. At this time, the quilt can be baked with a smaller air flow, and the remaining baking is completed using the residual heat. Finally, the user directly takes out the quilt dryer from the quilt. The quilt dryer provided in this embodiment enables the user to only perform the operations of putting in and taking out, greatly improving the convenience, and the quilt drying effect of the quilt dryer is good.
