Technical Field

[0001] The utility model relates to a blowing and drying device, in particular to a blowing and drying device used in the field of air drying of vehicle mats. Background Art

[0002] Before cleaning the vehicle mat, it is usually necessary to fix the mat in a certain position and then clean it. After cleaning, the mat is naturally air-dried. The air-drying efficiency is low and it takes a long time.

[0003] The utility model patent CN202322208721.9 discloses a blow dryer, in which a mat is placed on a support, and the mat is blown dry by controlling the back-and-forth movement of a gas generator and a blower. The air outlet direction of the blower is in one direction and cannot be changed. A limited number of mats can be blown dry at one time, and a maximum of four mats can be blown dry at one time. The other side of the mat cannot be blown and needs to be turned over, so there is room for improvement. Utility Model Content

[0004] The technical solution provides an improved blow-drying device, which adds a wind direction changing device at the hot air outlet to change the wind direction of the hot air so that multiple mats can be blown and dried. Both sides of the mats can be blown, which solves the problems that the wind direction of the hot air cannot be changed, the number of mats that can be blown and dried is limited, and the need to turn the mats over for blow-drying.

[0005] To achieve the above-mentioned purpose, the technical solution is the following blowing and drying equipment, characterized in that: it includes a gas generator, a heating module, a wind direction changing device, and a control unit; the control unit communicates and controls the gas generator, the heating module and the wind direction changing device and controls the actions of the gas generator, the heating module and the wind direction changing device; the gas generated by the gas generator generates hot air after passing through the heating module, and the hot air passes through the wind direction changing device, where the direction of the hot air changes back and forth, and then the mat is blown dry.

[0006] In the technical solution constructed as above, the gas generator generates hot air after passing through the heating module, and the control unit controls the wind direction changing device to move back and forth. After passing through the wind direction changing device, the hot air swings back and forth left and right to blow and dry the mat. When swinging from right to left, one side of the mat is blown and dried, and when swinging from left to right, the other side of the mat is blown and dried. There is no need to turn the mat over. Several to more than ten mats can be placed under the wind direction changing device to achieve blowing and drying of multiple mats at the same time.

[0007] In the present technical solution, it is preferred that the hot air flows from top to bottom, with the gas generator generating gas and passing through the heating module to generate hot air, and the hot air then passes through the wind direction changing device to blow dry the mat.

[0008] In the technical solution constructed as above, the hot air flows from top to bottom, and the gas generator, the heating module and the wind direction changing device are placed in sequence from top to bottom. In this way, the various components are placed up and down, and the spatial layout is reasonable. Multiple mats can be placed in the lateral direction of the space below, while the lateral dimension is shortened, thereby reducing the footprint of the entire blowing and drying equipment. This is extremely beneficial in car wash places with limited floor space and can save floor space.

[0009] In the present technical solution, the wind direction changing device preferably includes a first motor, a first motion mechanism and a shutter mechanism, the first motor is drivingly connected to the first motion mechanism, the first motion mechanism is connected to the shutter mechanism, and the control unit controls the first motor to drive the first motion mechanism to drive the shutter mechanism to swing back and forth to change the direction of the hot air.

[0010] In the technical solution constructed as above, the control unit controls the forward or reverse rotation of the first motor, and then drives the first motion mechanism to drive the shutter mechanism to swing back and forth to change the direction of the hot air. The purpose of swinging back and forth can be achieved by controlling the motor. The control is convenient, and the speed of swinging can be achieved through the speed of the motor. No complicated program design is required. The shutter mechanism can be driven to swing back and forth by indirect driving through the first motion mechanism, and the power transmission is proper.

[0011] In the present technical solution, the heating module is preferably a heating wire.

[0012] In the technical solution constructed as above, the heating wire is generally about 2 mm in diameter, and it is easy to install by winding it back and forth at the air outlet. Because of its small diameter, it reduces wind resistance and has high heat conversion efficiency. Compared with the heating tube, which generally has a larger diameter, it has a greater resistance to wind. The PTC heating method generally has low power and is difficult to install.

[0013] In the present technical solution, preferably, the first motion mechanism is a crank-connecting rod mechanism or a worm gear-connecting rod mechanism.

[0014] In the technical solution constructed as above, when a crank-connecting rod mechanism is used as the first motion mechanism of the wind direction changing device, the motor is connected to the crank, and the connecting rod is connected to the shutter mechanism. The crank rotates to drive the connecting rod, and the connecting rod can push or pull the shutter to swing back and forth. The motion mechanism is simple, and it can be achieved by controlling the motor to rotate forward or reverse all the time. The movement is stable and will not get stuck, which saves space, has a compact structure, and has high working stability. Another alternative method is to use a turbine-worm connecting rod mechanism. The power of the motor is connected to the worm, and the worm is meshed with the turbine. The turbine is connected to the shutter through a connecting rod. The motor is controlled to rotate forward or reverse all the time to drive the worm to rotate synchronously, thereby driving the turbine to rotate and drive the connecting rod to push or pull the shutter to swing back and forth. The transmission is smooth, the transmission ratio is large, the load-bearing capacity is strong, and the noise is low.

[0015] In the present technical solution, the shutter mechanism preferably includes two blades, and the two blades are connected by a rocker so that they can swing back and forth at the same time to change the wind direction.

[0016] In the technical solution constructed as above, the left and right blades of the shutter mechanism limit the leakage of hot air on the left and right sides, reducing the air volume loss. The two blades are connected by a rocker and swing at the same time to ensure that the air outlet area remains unchanged and the air outlet pressure does not change basically, thereby effectively improving the blowing and drying efficiency of the mat.

[0017] In the present technical solution, a three-dimensional spatial support frame is preferably placed below the wind direction changing device, and the three-dimensional spatial support frame is used to place a plurality of mats. The hot air passes through the wind direction changing device to swing the hot air back and forth to blow and dry the plurality of mats.

[0018] In the technical solution constructed as above, multiple mats can be placed in the three-dimensional spatial support frame, and the multiple mats are placed at intervals. The hot air swings back and forth left and right after passing through the wind direction changing device. The hot air passes through the gaps between the mats, and the gaps are set at a certain distance. The hot air accelerates the evaporation of moisture on both sides of the mat, thereby blowing and drying the mat.

[0019] In the present technical solution, preferably, the spatial three-dimensional support frame is also fixed on a reciprocating motion mechanism, and the control unit communicates with the reciprocating motion mechanism and controls the movement of the reciprocating motion mechanism to drive the three-dimensional support frame to move back and forth.

[0020] In the technical solution constructed as above, since the spatial three-dimensional support frame is fixed on the reciprocating motion mechanism, the mat is placed in the spatial three-dimensional support frame, the control unit communicates with the reciprocating motion mechanism and controls the movement of the reciprocating motion mechanism to drive the mat to move back and forth, and the mat shakes back and forth, further accelerating the evaporation of moisture on the surface of the mat. Moreover, the rate of blowing air through multiple mats is relatively accelerated, and the blowing and drying efficiency of the mat is further improved, thereby shortening the blowing and drying time.

[0021] In the present technical solution, the reciprocating motion mechanism preferably includes a second motor, a sliding member and a second motion mechanism, and the control unit controls the second motor to drive the second motion mechanism to drive the three-dimensional support frame to move back and forth.

[0022] In the technical solution constructed as above, the control unit controls the forward or reverse rotation of the second motor, and then drives the second motion mechanism to drive the sliding component to move back and forth and drive the spatial three-dimensional support frame to move back and forth. The purpose of swinging back and forth can be achieved by controlling the second motor. The control is convenient, and the speed of the swinging can be achieved through the speed of the motor. No complicated program design is required. The sliding component can be driven back and forth by indirect driving through the first motion mechanism. The power transmission is stable, and the control of the second motor and the first motor are independent. Each can be controlled to work independently without interference.

[0023] In the present technical solution, the second motion mechanism is preferably a crank-connecting rod mechanism or a worm gear-connecting rod mechanism.

[0024] In the technical solution constructed as above, by adopting the crank-connecting rod mechanism as the second motion mechanism of the reciprocating motion mechanism, the motor is connected to the crank, and the connecting rod is connected to the sliding assembly. The crank rotates to drive the connecting rod, and the connecting rod can push or pull the sliding assembly to move back and forth. The motion mechanism is simple, and it can be achieved by controlling the motor to rotate forward or reverse all the time. The motion is stable and will not get stuck, which saves space, has a compact structure, and has a high working stability. Another alternative method is to use a worm-turbine connecting rod mechanism. The power of the motor is connected to the worm, and the worm is meshed with the turbine. The turbine is connected to the sliding assembly through the connecting rod. The motor is controlled to rotate forward or reverse to drive the worm to rotate synchronously, thereby driving the turbine to rotate and drive the connecting rod to push or pull the sliding assembly back and forth. The transmission is smooth, the transmission ratio is large, the load-bearing capacity is strong, and the noise is low. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] For the purpose of facilitating understanding of the principles of the present disclosure, reference will now be made to the embodiments illustrated in the accompanying drawings described herein. The embodiments disclosed herein are not intended to be exhaustive or to limit the present invention to the precise form disclosed. Rather, the embodiments are selected and described so that other technicians in the field can make use of these teachings. Therefore, it is not desired to limit the scope of the claimed utility model. The present utility model includes any changes and further modifications to the illustrated apparatus and the described method that would be generally understood by a technician in the field to which the present utility model belongs, as well as further applications of the principles in the present utility model. It should be noted that, for ease of description, the following description will only be based on the example of a mat inside a vehicle being used for air drying in the air drying device of the present utility model, and the mat is a foot mat under the seat in the vehicle, but it is not limited to this.

[0055] The three-dimensional spatial support frame may be fixed to the reciprocating motion mechanism directly or indirectly, as long as the three-dimensional spatial support frame and the reciprocating motion mechanism can move synchronously.

[0056] Figure 1-Figure 3 The diagram shows a schematic diagram of a blowing and drying device 1000 in the first embodiment of the utility model. The blowing and drying device 1000 includes a housing 1, a gas generator 3, a wind direction changing device 5, a guide 4, a reciprocating motion mechanism 6, a three-dimensional spatial support frame 7 and a control unit. A universal wheel 2 is installed at the bottom of the housing 1, so that the blowing and drying device 1000 can be pushed to move, which has the effect of convenient steering and labor saving. The gas generator 3 is fixed in the upper space 11 of the housing 1, the wind direction changing device 5 and the guide 4 are fixed in the lower space 12 of the housing 1, the reciprocating motion mechanism 6 and the three-dimensional spatial support frame 7 are also fixed in the lower space 12 of the housing 1 and are located below the wind direction changing device 5. The upper space 11 and the lower space 12 are separated by a partition. The gas generator 3 is connected to the guide 4. The gas generator 3 and the guide 4 are both fixed on the partition (fixed by screws, not shown in the figure). The bottom of the housing 1 A hollow portion 8 is also provided. When the blowing and drying device 1000 blows and dries the mat, the hollow portion 8 at the bottom can allow water vapor to flow away, thereby preventing water vapor from accumulating in the box body 1 and affecting the blowing and drying. In addition, an air guide port 9 is also provided at the lower portion of the rear side surface of the box body 1. When the blowing and drying device 1000 blows and dries the mat, hot air flows from top to bottom and can be guided out from the inside to the outside, thereby forming a circulating blowing and drying method. The blowing and drying efficiency of the mat is improved, and the box body 1 can be formed in one piece or by welding.

[0057] See also Figure 7 , further comprising a heating module 10, the heating module 10 being fixed in the air guide channel of the guide 4. Figure 6The wind direction changing device 5 includes a first motor 51, a first motion mechanism 52 and a shutter mechanism 53. The first motor 51 is supported on a mounting bracket 5101. The power output shaft 5102 of the first motor 51 is drivingly connected to the first motion mechanism 51. The first motion mechanism 52 includes a crank 5201 and a connecting rod 5202. The crank 5201 and the connecting rod 5202 are hingedly connected. The crank 5201 is drivingly connected to the power output shaft 5102 of the first motor 51 through a key. The shutter mechanism 53 includes two left and right blades, which are the first blades. 5301 and the second fan blade 5302, the first fan blade 5301 and the second fan blade 5302 are movably connected by a rocker 5303 hinge, and the front and back of the first fan blade 5301 and the second fan blade 5302 are respectively covered by two flexible fan blades 5304, and the flexible fan blades 5304 are specifically made of accordion covers, so as to form a closed space 5305 closed on all sides to prevent hot air from leaking from the four sides of the shutter mechanism 5, and hot air can only be discharged from the bottom, ensuring that the air outlet area remains basically unchanged, and the air outlet pressure does not change basically, which effectively improves the air drying efficiency of the mat. Figure 4 and Figure 5 The bracket 5101 is fixed on the first fixing plate 17 on the rear side plate of the box body 1, and the second motor 61 included in the reciprocating motion mechanism 6 is fixed on the second fixing plate 18 on the rear side plate of the box body 1.

[0058] Since the crank 5201 is connected to the power output shaft 5102 of the first motor 51 by a key, when the control unit controls the power output shaft 5102 of the first motor 51 to rotate, the crank 5201 is synchronized with the power output shaft 5102, and the crank 5201 can push or pull the connecting rod 5202 to swing back and forth, and the connecting rod 5202 is connected to the lower fulcrum hinge of the first fan blade 5301, so that the first motion mechanism 52 is driven to drive the shutter mechanism 53 to swing back and forth to change the direction of the hot air. In the process of swinging back and forth, the side area between the first fan blade 5301 and the second fan blade 5302 changes from a parallelogram to a rectangle and then to a parallelogram, so two flexible fan blades 5304 are used for covering, and the flexible fan blades 5304 can be elastically extended and retracted, and change with the shape to meet the requirements.

[0059] See again Figure 7The shutter mechanism 5 also includes a fixing frame 5306, which is fixed to the vertical protrusion 48 below the guide 4 by screws to form a detachable connection, which is convenient for installation and fixing. The gas generator 3 generates air and then passes through the heating module 4 to generate hot air. The hot air flows from the gas generator 3 to the guide 4 from top to bottom. The hot air then swings back and forth after passing through the shutter mechanism 53 in the wind direction changing device 5. The control unit controls the wind direction changing device 5 to move back and forth. After passing through the wind direction changing device 5, the hot air swings back and forth to the left and right, and the mat placed in the three-dimensional support frame 7 below is blown and dried. When swinging from right to left, one side of the mat is blown and dried, and when swinging from left to right, the other side of the mat is blown and dried. It is not necessary to turn over. Several to more than ten mats can be placed under the wind direction changing device 5 to achieve simultaneous blowing and drying of multiple mats. The hot air flows from top to bottom, and the gas generator 3, the heating module 10 and the wind direction changing device 5 are placed in sequence from top to bottom. In this way, the various components are placed up and down, and the spatial layout is reasonable. Multiple mats can be placed in the lateral direction of the lower space while shortening the lateral dimension, thereby reducing the footprint of the entire blowing and drying equipment 1000. This is extremely beneficial in a car wash place with limited floor space, and can save floor space.

[0060] See also Figure 8 The heating module 10 includes a heating wire 101 and a frame 102. The heating wire 101 is spirally wound on the outer circumference of the frame 102. The heating wire generally has a diameter of about 2 mm. It is easy to install by winding it back and forth at the air outlet. Because of its small diameter, it reduces wind resistance and has high heat conversion efficiency. Compared with the heating tube, which generally has a larger diameter, it has greater resistance to wind. The PTC heating method generally has low power and is difficult to install. The frame 102 adopts a cross-shaped frame and is placed vertically to further reduce wind resistance and reduce the loss of wind pressure and air volume.

[0061] See also Fig. 9 and Fig.10 The gas generator 3 has a rectangular air outlet 31 , and the air outlet area S1 of the air outlet 31 is S1 = L1 * W1 .

[0062] See also Fig.11 — Fig.13The guide 4 includes a front side plate 42, a rear side plate 42, a left side plate 43 and a right side plate 44. The guide 4 also has an air inlet 45. The air inlet area of ​​the air inlet 45 is equal to the air outlet area S1 of the air outlet 31 of the gas generator 3. The front side plate 42 and the rear side plate 42 gather inward, and the left side plate 43 and the right side plate 44 expand outward to form a guide channel. The guide 4 is in a prism shape, and the guide air outlet area S2 of the air outlet 47 of the guide channel is S2 = L2*W2. The guide 4 can be formed in one piece. With such arrangement, the gas generated by the gas generator 3 passes through the heating module 10 to generate hot air, which passes through the guide channel of the guide 4. The hot air is guided by the guide 4 and the blowing width of the hot air is expanded. The outlet width of the hot air at this time is greater than the outlet width L1 of the gas generator. The entire outlet spans the width direction of the mat, fully covering the mat to prevent the mat from having a dead corner for blowing. The outlet area S2 from the guide 4 is less than or equal to the outlet area S1 of the gas generator 3 (i.e., L1≤L2, W1≥W2), ensuring that the final outlet pressure is greater than or equal to the outlet pressure of the gas generator. In this way, when selecting a gas generator, a gas generator with a smaller power can also meet the requirements and save electricity. If the final outlet area is greater than or equal to the outlet area of ​​the gas generator, the outlet pressure is reduced, and a gas generator with a larger power needs to be selected to meet the requirements, which consumes a larger amount of electricity. The inner walls of the left plate 43 and the right plate 44 of the guide 4 further have fixing columns 46 for fixing the heating module 10 in the air guide channel of the guide 4 .

[0063] Return to Reference Figure 7 , continue reading Fig.14 and 15, which shows a first embodiment of the wind direction changing device 5, wherein the power output shaft of the first motor 51 is fixedly connected to one end of the crank 5201, and the other end of the crank 5201 is hingedly connected to one end of the connecting rod 5202, and the other end of the connecting rod 5202 is hingedly connected to a rotating fulcrum at the lowest end of the first fan blade 5301 and opposite to the rotating point 5307, and the two ends of the rocker 5303 are hingedly connected to the first fan blade 5301 and the second fan blade 5304 respectively. The control unit controls the forward or reverse rotation of the first motor 31, and then drives the first motion mechanism 52 to drive the shutter mechanism 53 to swing back and forth to change the direction of the hot air. The purpose of swinging back and forth can be achieved by controlling the motor, which is convenient to control. The speed of the swinging can be achieved by the speed of the motor, and no complicated program design is required. The shutter mechanism can be driven to swing back and forth by indirect driving through the first motion mechanism, and the power transmission is proper. When the shutter mechanism 53 swings from right to left to the maximum position, and then swings from left to right to the maximum position, the swing angle is A, and the mat below the angle A can be blown and dried. More importantly, the torque of the connection between the crank 5201 and the connecting rod 5202 is the largest, and the torque driven by the first motor 51 is also the largest. Only a small force is needed to drive the first motion mechanism 52 to drive the shutter mechanism 53 to swing back and forth at the angle A. Selecting a first motor 52 with a smaller power can meet the demand and save power.

[0064] See also Fig.16 and Fig.17 , shows the second embodiment of the wind direction changing device 5, which is different from the first embodiment in that the connection position of the crank is different and the installation position of the first motor is different. Specifically, the crank is connected to the hinge rotation connection fulcrum position 5307 near the upper end of the first fan blade 5308 of the shutter mechanism, so that the torque formed is small, the length required for the crank and the connecting rod is small, and the space occupied by the crank-connecting rod mechanism is reduced. In addition, the biggest advantage is that when the control unit controls the first motor to rotate forward or reverse, when the shutter mechanism 53 swings from right to left to the maximum position, and then swings from left to right to the maximum position, a large swing angle A1 can be formed, and the large angle A1 covers a larger range, and more mats can be blown and dried at one time. The first motor can be installed at a higher position, and the wind direction changing device 5 can be closer to the three-dimensional support frame 7 below, so that the height of the blowing and drying device 1000 can be reduced. When the crank-connecting rod mechanism is used as the first motion mechanism 52 of the wind direction changing device 5, it can be achieved by controlling the motor to rotate forward or reverse all the time, and the motion is stable and will not get stuck, saving space, compact structure, and high working stability.

[0065] See also Figure 18-19, shows a second embodiment of the blowing and drying device 2000, which differs from the first embodiment of the blowing and drying device 1000 in that the first motor installation position in the wind direction changing device 5 is different, the first motion mechanism is different, and the installation position of the lower reciprocating motion mechanism 6 is different. Specifically, the first motor 5207 in the wind direction changing device 5 is installed horizontally and fixed on the upper mounting bracket, while the first embodiment is fixed on the lower bracket. The first motion mechanism adopts a turbine worm mechanism, including a support plate 5203, a turbine 5204, a worm 5205 and a power output shaft 5206 of the first motor 5207, the turbine 5204 is supported and installed on the support plate 5203, and the support plate 5203 is fixed on the first motor 5207. The power output shaft 5206 of the first motor 5207 is fixedly connected to the worm 5205, the worm 5205 is meshed with the turbine 5204, and the turbine is connected to the shutter mechanism through a connecting rod. The first motor 5207 is controlled to rotate forward or reverse to drive the worm to rotate synchronously, thereby driving the turbine to rotate and drive the connecting rod to push or pull the shutter to swing back and forth, with smooth transmission, large transmission ratio, strong load-bearing capacity and low noise.

The grid frame 72 adopts a three-dimensional wire grid frame, and has multiple compartments 7201 from left to right. The multiple compartments 7201 are relatively close in spacing, with a spacing of 20mm-40mm. The multiple compartments 7201 can hold multiple mats 79, and when all the mats 79 are filled, about 10-20 mats can be placed.

[0067] The sliding assembly includes a sliding rod 63 and a slider 64. Two sliding rods 63 are placed opposite each other in the front and back, and four sliders 64 are placed in the front and back, left and right. The left strip 7103 and the rear strip 7104 of the screen frame 7 are fixed on the left and right sides of the sliding assembly, respectively, and are specifically fixed on the upper and lower sliders on the left and the two sliders on the right (fixed with screws, not shown in the figure). The power output shaft 62 of the second motor 61 is rotatably connected to the second motion mechanism 65. The second motion mechanism adopts a crank-connecting rod mechanism, and the connecting rod of the crank connection mechanism is rotatably connected to the slider 64. Return to reference Figure 2The sliding assembly is fixed at an upper position of the lower space 12 of the box body 1, and the second motor is also fixed at an upper position of the lower space 12 of the box body 1. In this way, when the pad 79 under the sliding assembly is blown and dried, the second motor 61 is prevented from being affected by water vapor. At the same time, the second motor is also easy to be electrically connected to the control unit by wiring, and only a shorter wire is needed.

[0068] A sliding assembly and a spatial three-dimensional support frame 7 are placed in sequence below the wind direction changing device 5. Multiple mats can be placed in the spatial three-dimensional support frame. Multiple mats 79 are placed at intervals. After passing through the wind direction changing device 5, the hot air swings back and forth left and right. The hot air passes through the gaps between each mat 79, and the gaps are set at a certain distance. The hot air accelerates the evaporation of moisture on both sides of the mat, thereby blowing and drying the mat.

[0069] When the control unit controls the second motor 61 to rotate forward or reverse to drive the sliding assembly to move a short stroke L3 to the left or right through the crank connecting rod mechanism, since the spatial three-dimensional support frame 7 is fixed on the sliding assembly, the spatial three-dimensional support frame 7 also moves a short stroke L3 to the left or right synchronously with the sliding assembly, and the mat is placed in the mesh frame 72 of the three-dimensional support frame, and the mat also moves back and forth in a short stroke left and right. During the left and right movement, the mat shakes, further accelerating the evaporation of moisture on the surface of the mat (similar to the principle of drying wet clothes), and the speed of blowing through multiple mats is relatively accelerated, and the blowing and drying efficiency of the mat is further improved, shortening the blowing and drying time. The purpose of moving back and forth can be achieved by simply controlling the second motor 71 to rotate forward or reverse, and the control is convenient. The speed of the sliding assembly can be achieved by the speed of the motor, and no complicated program design is required. The sliding assembly can be driven to move back and forth by indirect driving through the second motion mechanism, and the power transmission is stable. The control of the second motor and the first motor is independent, and each can be controlled to work independently without interference. The function of the crank-connecting rod mechanism is the same as that of the crank-connecting rod mechanism in the wind direction changing device 5. Alternatively, a turbine-worm gear connecting rod mechanism can also be used as the second motion mechanism 65 in the reciprocating motion mechanism 6. Its specific structure is the same as that of the turbine-worm gear mechanism in the wind direction changing device 5, and will not be repeated here.

[0070] See also Figure 24-26, shows a second embodiment of the reciprocating motion mechanism and the spatial three-dimensional support frame in the air drying device 2000, which differs from the first embodiment in that the net frame is cancelled, a drawer 2003 is added, and the installation position of the sliding assembly is different from the placement position of the spatial three-dimensional support frame. Specifically, the spatial three-dimensional support frame only includes a net frame 20, which is placed in the drawer 2003, and a sliding guide 2004 is provided below the drawer. A frame 2001 is fixedly installed on the sliding assembly, and a sliding guide groove 2002 is provided on the frame 2001. The second motor 2008 is placed on the lower right side of the sliding assembly, and the mat 2009 is placed in the net frame 20. The net frame is placed in the drawer 2003, and the drawer can be easily pushed into the frame 2001 through the cooperation of the sliding guide 2004 and the sliding guide groove 2002. The second motor 2008 is controlled by the control unit to rotate forward or reverse, and the second motor 2008 drives the second motion mechanism 2007 to drive the slider 2005 to slide on the slide bar, thereby driving the mat to move back and forth. The second motion mechanism 2007 can be a crank connecting rod mechanism or a worm gear connecting rod mechanism, and its specific driving method is the same as that of the first embodiment, which will not be repeated here. The handle 2006 facilitates pushing the drawer 2003 to push the rack 20 into the guide groove 2002 on the frame 2001. In this way, the reciprocating motion mechanism is placed below the three-dimensional support frame to prevent the hot air blowing downward from being blocked by the net movement mechanism.

[0071] See also Fig. 27 and 28 , showing the blowing and drying device 3000 in the third embodiment, mainly the spatial three-dimensional support frame is different, specifically the distance between the compartments 3001 of the net frame is different, the spacing between each compartment 3001 is relatively large, the spacing is between 50mm-70mm, and it is used to place fewer mats. Each mat 3002 is placed in each compartment 3001, and the spacing between them is large, so it is easier for hot air to pass through the surface of the mat. The wind direction changing device can be controlled to swing quickly or the reciprocating motion mechanism can be controlled to move quickly to achieve rapid blowing and drying of the mat, greatly reducing the blowing and drying time, and is applied in different scenarios.

[0072] The gas generator preferably adopts an air pump, a fan or a gas compressor. When the gas generator adopts a fan, for example, a crossflow fan, a centrifugal fan, a comb flow fan, a crossflow fan, a multi-leaf fan, a mixed flow fan and a vortex fan can be adopted. The fan can adopt the fan structure in the patents such as JP1994056155B2, JP6051403B2, and JP7213415B2 of Panasonic. Its specific structure is discussed in detail in the patent, and will not be repeated here. The gas generator of this technical solution specifically adopts a centrifugal fan. The centrifugal fan has a long life and can be used for at least 3-5 years without breaking. It can adapt to relatively harsh environments, especially in car wash places with serious water vapor, and will not be affected basically. It is purchased from Shanghai Yingda Fan Co., Ltd. The outer rotor double air inlet air conditioner has a fan flow rate of 1500-3000 cubic meters per second and an average speed of 1360r / min. The structure is specifically disclosed in the CN211975442U patent.

[0073] See also Fig.29 , return to see Figure 1 , is a logic control diagram of the blowing and drying device of the utility model. The control unit communicates with the wind direction changing device, the reciprocating motion mechanism, the gas generator, the temperature sensor, the humidity sensor and the heating module. The control unit can set the blowing and drying time of the blowing and drying device, the air volume and air pressure, the swing speed of the wind direction changing device and the moving speed of the reciprocating motion mechanism. For example, if it is set to 8 minutes, the gas generator will work within 8 minutes, the wind direction changing device will work at the set swing speed and the set moving speed of the reciprocating motion mechanism, and the hot air will blow and dry the mat after passing through the wind direction changing device, and it will stop automatically after the time is up. The blowing and drying device also includes a temperature sensor and a humidity sensor. The temperature sensor and the humidity sensor detect the temperature value and humidity value of the mat in real time, and transmit the detected temperature value and humidity value of the mat to the control unit for comparison with the temperature threshold and the humidity threshold to determine the moisture and humidity on the surface of the mat to control the start and stop of the blowing and drying component 61.

[0074] The control unit can also control the start and stop of the gas generator, the size of the heating module output power to control the hot air outlet temperature; the control unit is operated through an external controller, and the controller can be an operation display panel and button on the upper surface of the housing 1 of the blowing and drying equipment 1000. The operation display panel 13 can display the air temperature, air volume and air pressure, and the blowing and drying setting time. The switch key 15 can operate to start and stop the blowing and drying equipment 1000. Buttons or knobs can be used. The temperature adjustment member 814 and the air volume adjustment key 13 can be operated to adjust the temperature and air volume respectively. The operation display panel can adjust the temperature and air volume steplessly, so that the required air outlet temperature and air volume can be adjusted in any temperature range and air volume range defined by it to meet the needs of blowing and drying different types of mats and mats with different moisture content, or the control panel can adjust the air outlet temperature and air volume in multiple gears, such as "setting high, medium and low gears" for different scenes, with strong applicability. The operation panel 13 uses a liquid crystal touch screen to display the temperature and air volume values, which is intuitive and clear at a glance.

[0075] In addition, a dehumidification module can be installed in the box of the air drying device. When the hot air blows and dries the mat in the three-dimensional support frame, since the air drying process easily generates fog and makes the support frame relatively humid, the dehumidification module can remove the moisture in the support frame to prevent the moisture from affecting the subsequent air drying of the mat and reducing the air drying efficiency. A waterproof UV sterilization lamp is also installed inside the box 1 for sterilizing the mat.

[0076] Return to Reference Figure 1 and Figure 2 The hair drying device 1000 also includes a switchable door. The hinged door is opened, and the mat is placed in the three-dimensional support frame 7. The three-dimensional support frame is then placed in the lower space 12 in the box body 1. The door is closed to prevent people standing in front of the mat from getting wet by water vapor during hair drying, and to prevent the mat from shaking and falling out. The hinged door is not shown in the figure, which is a conventional technology.
