Description

Technical Field

[0001] The present invention relates to a blowing and drying device, in particular to a blowing and drying device used in the field of drying 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-drying machine, in which a mat is placed on a support, and the mat is blown and dried by controlling the back-and-forth movement of a gas generator and an air outlet. The mat is placed in a support module and is fixed, and the air outlet moves back and forth to blow and dry the mat. The number of mats blown and dried at one time is limited, and the mat does not move or shake. The efficiency of the blow-drying needs to be improved, and there is room for improvement. Summary of the Invention

[0004] The present invention is made to solve the above-mentioned problems, and can at least solve one of the above-mentioned problems, and further provide an improved blowing and drying equipment, in which the mat is placed in a three-dimensional spatial support frame, and the three-dimensional spatial support frame is fixed on a reciprocating motion mechanism. Several mats can be placed on the three-dimensional support frame at a time, and the gas generator generates gas which passes through the heating module to generate hot air. The control unit controls the reciprocating motion mechanism to move back and forth, thereby driving the mat in the three-dimensional spatial support frame to move back and forth and shake. Several mats can be placed on the three-dimensional spatial support frame, and multiple mats can be blown and dried at the same time. More than a dozen mats can be blown and dried at the same time, thereby increasing the number of blown and dried mats. The mats move back and forth and shake, which accelerates the evaporation of moisture on the surface of the mats, and the blowing and drying efficiency of the mats is further improved.

[0005] To achieve the above-mentioned purpose, the present invention is the following blowing and drying equipment, characterized in that: a gas generator, a heating module, a spatial three-dimensional support frame, a reciprocating motion mechanism and a control unit; the control unit communicates and controls the gas generator, the heating module and the reciprocating motion mechanism and controls the actions of the gas generator, the heating module and the reciprocating motion mechanism; the spatial three-dimensional support frame is fixed on the reciprocating motion mechanism, the control unit communicates with the reciprocating motion mechanism and controls the reciprocating motion mechanism to move, the spatial three-dimensional support frame is used to place a mat, and the gas generator generates gas that passes through the heating module to generate hot air that is blown towards the mat in the spatial three-dimensional support frame for blowing and drying.

[0006] In the present invention thus constructed, the spatial three-dimensional support frame is fixed on the reciprocating motion mechanism, and the mat is fixed in the spatial three-dimensional support frame. The control unit communicates with the reciprocating motion mechanism and controls the reciprocating motion mechanism to move, thereby driving the mat in the spatial three-dimensional support frame to move back and forth and shake. Several mats can be placed on the spatial three-dimensional support frame, and multiple mats can be blown and dried at the same time. More than a dozen mats can be blown and dried at the same time, which increases the number of blown and dried mats. The mat moves back and forth and shakes, which accelerates the evaporation of moisture on the surface of the mat, and the blowing and drying efficiency of the mat is further improved. The reciprocating motion mechanism is located above the spatial three-dimensional support frame, so that when the control unit communicates with the reciprocating motion mechanism, the wiring is short and the wire layout is convenient. When the mat in the spatial three-dimensional support frame is blown and dried, the reciprocating motion mechanism can also be prevented from being affected by water vapor.

[0007] In the present invention, it is preferred to further include a wind direction changing device and a guide; the control unit communicates with the wind direction changing device and controls the action of the wind direction changing device; the gas generator generates gas which passes through the heating module and then generates hot air which passes through the guide, the guide guides the hot air and expands the blowing width of the hot air, the air outlet area of ​​the gas generator is greater than or equal to the air guide port area of ​​the guide, and the hot air passes through the wind direction changing device and then the direction of the hot air changes back and forth to blow the mat dry.

[0008] In the present invention thus constructed, the gas generator generates hot air after passing through the heating module, and the hot air expands the blowing width of the hot air after passing through the guide. The outlet width of the hot air at this time is greater than the outlet width of the gas generator. The entire outlet spans the width direction of the mat, fully covering the mat to prevent the occurrence of dead corners in the mat; the outlet area of ​​the gas generator is greater than or equal to the air guide port area of ​​the guide, that is, the outlet area of ​​the guide is less than or equal to the outlet area of ​​the gas generator, 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 smaller power can also meet the requirements. The requirements are met and electricity is saved. If the final air outlet area is greater than or equal to the air outlet area of ​​the gas generator, the air outlet pressure is reduced, and a larger power gas generator needs to be selected to meet the requirements, which consumes a larger amount of electricity. The control unit controls the wind direction changing device to move back and forth, and the hot air swings back and forth left and right after passing through the wind direction changing device 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 blow and dry multiple mats at the same time.

[0009] In the present invention, 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.

[0010] In the present invention thus constructed, the hot air flows through a path from top to bottom, and the gas generator, heating module and 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 lower space while shortening the lateral dimension, 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.

[0011] In the present invention, the wind direction changing device preferably includes a first motor, a first motion mechanism and a shutter mechanism. The first motor is driven and connected to the first motion mechanism, and the first motion mechanism is connected to the shutter mechanism. 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.

[0012] In the present invention thus constructed, 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 simply controlling the motor. The control is convenient, and the speed of the swinging can be achieved by the speed of the motor. No complicated program design is required. The shutter mechanism can be driven to swing back and forth indirectly through the first motion mechanism, and the power transmission is proper.

[0013] In the present invention, it is preferred that the first motion mechanism is a crank-connecting rod mechanism or a worm gear-connecting rod mechanism.

[0014] In the present invention thus constructed, 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 engaged 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 invention, it is preferred that the connecting rod of the crank connecting rod mechanism is rotatably connected to the downstream end of the shutter mechanism or the connecting rod of the worm gear connecting rod mechanism is rotatably connected to the downstream end of the shutter mechanism.

[0016] In the present invention thus constructed, since the connecting rod hinge of the crank-connecting rod mechanism is rotatably connected to the downstream end of the shutter mechanism or the connecting rod hinge of the worm gear connecting rod mechanism is rotatably connected to the downstream end of the shutter mechanism; the torque between the connecting rod and the shutter mechanism is large, the first motor only needs a small driving force to drive the shutter mechanism to swing back and forth, and the required electrical power is small, which saves energy and thus saves electricity costs.

[0017] In the present invention, it is preferred that the connecting rod of the crank connecting rod mechanism is rotatably connected to the downstream end of the shutter mechanism or the connecting rod of the worm gear connecting rod mechanism is rotatably connected to the upstream end of the shutter mechanism.

[0018] In the present invention thus constructed, since the connecting rod hinge of the crank-connecting rod mechanism is rotatably connected to the downstream end of the shutter mechanism or the connecting rod hinge of the worm gear connecting rod mechanism is rotatably connected to the upstream end of the shutter mechanism; the torque between the connecting rod and the shutter mechanism is very small, the length of the connecting rod can be made very small, so that the space occupied by the crank-connecting rod mechanism or the worm gear connecting rod mechanism is further reduced, the first motor drives the shutter mechanism to swing back and forth to a greater angle, the hot air of the shutter mechanism can cover a larger range to blow and dry more mats, and the distance between the shutter mechanism and the mats can be shortened to reduce the height of the entire blowing and drying equipment.

[0019] In the present invention, the shutter mechanism preferably includes two fan blades and two flexible fan blades, and the two fan blades are connected by a rocker so that they can swing back and forth at the same time to change the wind direction; the two flexible fan blades are respectively placed on both sides of the two fan blades to form a closed space enclosed on all sides to prevent hot air from leaking from the sides of the wind direction changing device and only being able to discharge air from the bottom.

[0020] In the present invention thus constructed, the left and right blades of the shutter mechanism limit the left and right side leakage of hot air, reducing air volume loss. The two blades are connected by a rocker and swing simultaneously, ensuring that the air outlet area remains unchanged and the air outlet pressure remains substantially unchanged, effectively improving the efficiency of air drying the mat. During the back-and-forth swinging of the shutter mechanism in the wind direction changing device, the side area between the first blade and the second blade changes from a parallelogram to a rectangle and then to a parallelogram. Therefore, two flexible blades are used for covering. The flexible blades can be elastically extended and retracted, changing with the shape to meet the requirements. The enclosed space thus formed prevents hot air from leaking from the four sides of the shutter mechanism. The hot air can only be discharged from the bottom, ensuring that the air outlet area remains unchanged and the air outlet pressure remains substantially unchanged, preventing air volume loss and further improving the efficiency of air drying the mat.

[0021] In the present invention, 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 present invention thus constructed, 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, driving 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 swinging can be achieved by the speed of the motor. No complicated program design is required. The sliding component can be driven back and forth by indirect drive 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 invention, it is preferred that the second motion mechanism is a crank-connecting rod mechanism or a worm gear-connecting rod mechanism.

[0024] In the present invention thus constructed, by adopting a 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. 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 gear connecting rod mechanism. The power of the motor is connected to the worm, and the worm is engaged 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

[0052] For the purpose of facilitating an 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 invention to the precise form disclosed. Rather, the embodiments are selected and described so that other persons skilled in the art can make use of these teachings. Therefore, further limitation of the scope of the claimed invention is not desired. The present invention includes any changes and further modifications to the illustrated apparatus and described methods that would be generally understood by persons skilled in the art to which the present invention pertains, as well as further applications of the principles of the present invention. It should be noted that, for ease of description, the following description will only be based on an example of a mat inside a vehicle being used for air drying in the air drying device of the present invention, where the mat is a foot mat under the front and rear seat cushions, but the invention is not limited thereto.

[0053] 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.

[0054] Figure 1-Figure 3 The diagram shows a schematic diagram of a blowing and drying device 1000 in the first embodiment of the present invention. 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 spatial three-dimensional 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 spatial three-dimensional 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 part 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 process. The blowing and drying efficiency of the mat is improved, and the box body 1 can be integrally formed or welded.

[0055] 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 driven and 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 driven and connected to the power output shaft 5102 of the first motor 51 through a key. The shutter mechanism 53 includes two left and right fan blades, which are the first fan blades. 5301 and the second fan blade 5302 are movably connected by a rocker 5303 hinge. 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. The flexible fan blades 5304 are specifically made of accordion covers. Thus, a closed space 5305 is formed on all sides to prevent hot air from leaking from the four sides of the shutter mechanism 5. Hot air can only be discharged from the bottom, ensuring that the air outlet area remains basically unchanged and the air outlet pressure remains basically unchanged, thereby effectively improving 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.

[0056] Since the crank 5201 is connected to the power output shaft 5102 of the first motor 51 through 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. The connecting rod 5202 is hinged and connected to the lower fulcrum of the first fan blade 5301, thereby driving the first motion mechanism 52 to drive the shutter mechanism 53 to swing back and forth to change the direction of the hot air. During the back and forth swinging process, 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. Therefore, two flexible fan blades 5304 are used for covering. The flexible fan blades 5304 can be elastically extended and retracted, changing with the shape to meet the requirements.

[0057] 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 that passes through the heating module 4 to generate hot air. The hot air flows from the gas generator 3 to the bottom through the guide 4. The hot air then passes through the shutter mechanism 53 in the wind direction changing device 5 and then swings back and forth. 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 in the left and right directions, blowing and drying the mat placed in the three-dimensional spatial support frame 7 below. 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 5 to achieve simultaneous 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 horizontal direction of the lower space while shortening the horizontal dimension, thereby reducing the footprint of the entire blowing and drying equipment 1000. This is extremely beneficial in car wash places with limited floor space and can save floor space.

[0058] See Figure 8 The heating module 10 includes a heating wire 101 and a skeleton 102. The heating wire 101 is spirally wound on the outer circumference of the skeleton 102. The diameter of the heating wire is generally 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 and poses greater resistance to wind, the PTC heating method generally has low power and is difficult to install. The skeleton 102 adopts a cross-shaped skeleton and is placed vertically to further reduce wind resistance and reduce the loss of wind pressure and air volume.

[0059] See Figure 9 and Figure 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 .

[0060] See Figure 11 — Figure 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, and then 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 occurrence of dead corners in the mat; 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 smaller power gas generator 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 larger power gas generator needs to be selected to meet the requirements, which requires a larger amount of electricity. The inner walls of the left side plate 43 and the right side 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 .

[0061] Return to Reference Figure 7 , continue reading Figure 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 the lower end of the first fan blade 5301 and a rotating fulcrum opposite to the rotating point 5307. 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. No complicated program design is required. The shutter mechanism can be driven to swing back and forth by indirect drive through the first motion mechanism, and the power transmission is proper. When the shutter mechanism 53 swings from right to left to its maximum position, and then from left to right to its maximum position, the swing angle is A. The mats below the range of angle A can be dried by air. Furthermore, the torque of the connection between the crank 5201 and the connecting rod 5202 is the largest, and the torque of the first motor 51 is also the largest. Only a small force is required to drive the first motion mechanism 52 to drive the shutter mechanism 53 to swing back and forth through angle A. Selecting a smaller power first motor 52 can meet the requirements, saving power.

[0062] See also Figure 16 and Figure 17 , shows a second embodiment of the wind direction changing device 5, which differs from the first embodiment in the connection position of the crank and the installation position of the first motor. Specifically, the crank is connected to the hinge connection fulcrum 5307 near the upper end of the first blade 5308 of the shutter mechanism. This generates a smaller torque, reduces the required length of the crank and connecting rod, and reduces the space occupied by the crank-connecting rod mechanism. In addition, the biggest advantage is that when the control unit controls the first motor to rotate forward or reverse, the shutter mechanism 53 can swing from right to left to its maximum position, and then from left to right to its maximum position, a large swing angle A1 can be formed. The large angle A1 covers a larger area, allowing more mats to be blown and dried at one time. The first motor can be installed in a higher position, and the wind direction changing device 5 can be closer to the three-dimensional support frame 7 below. This can reduce the height of the drying device 1000. When the crank-connecting rod mechanism is used as the first motion mechanism 52 of the wind direction changing device 5, the motor can be controlled to rotate forward or reverse continuously, which can achieve stable motion without jamming, saving space, and having a compact structure and high operational stability.

[0063] See Figures 18-20, shows a second embodiment of a blow-drying device 2000. This differs from the first embodiment of the blow-drying device 1000 in the installation position of the first motor in the wind direction changing device 5, the first motion mechanism, and the installation position of the lower reciprocating motion mechanism 6. Specifically, the first motor 5207 in the wind direction changing device 5 is mounted horizontally and fixed to the upper mounting bracket, whereas in the first embodiment, it was fixed to the lower bracket. The first motion mechanism utilizes a worm gear mechanism, including a support plate 5203, a turbine 5204, a worm gear 5205, and a power output shaft 5206 for the first motor 5207. The turbine 5204 is supported and mounted on the support plate 5203, which is in turn fixed to 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 engaged 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. The transmission is smooth, the transmission ratio is large, the load-bearing capacity is strong, and the noise is low.

[0064] See Figure 21-24 This is a specific first embodiment of the reciprocating motion mechanism 6 and the spatial three-dimensional support frame 7 in the blowing and drying equipment 1000. The reciprocating motion mechanism 6 includes a second motor 61 and a sliding component. The spatial three-dimensional support frame 7 includes a mesh frame 71 and a mesh frame 72. The mesh frame 71 includes the upper front strip 7101, the rear strip 7102, the left strip 7103, the rear strip 7104, the left mesh plate 7105, the right mesh plate 7106 and the bottom mesh plate 7107. The mesh frame 71 is integrally formed and can also be formed by welding. The front strip 7101, the rear strip 7102, the left strip 7103, the rear strip 7104, the left mesh plate 7105, the right mesh plate 7106 and the bottom mesh plate 7107 constitute an internal space 7108, and the mesh frame 72 is placed in the internal space 7108 of the mesh frame 71. The grid 72 is a three-dimensional wire grid having a plurality of compartments 7201 from left to right. The compartments 7201 are spaced relatively close together, with a spacing of 20 mm to 40 mm. The compartments 7201 can hold a plurality of mats 79 , and when the plurality of mats 79 are fully filled, approximately 10 to 20 mats can be placed therein.

[0065] The sliding assembly includes two slide rods 63 and sliders 64. Two slide rods 63 are placed opposite each other in the front and back, and four sliders 64 are placed in the front, back, left and right. The left strip 7103 and the rear strip 7104 of the screen frame 7 are respectively fixed to the left and right sides of the sliding assembly, specifically to 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 mat 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 wire and electrically connect with the control unit, and only a short wire is needed.

[0066] The sliding assembly and the 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, and the multiple mats 79 are placed at intervals. After the hot air passes through the wind direction changing device 5, it swings back and forth. 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.

[0067] When the control unit controls the second motor 61 to rotate forward or reverse via the crank-connecting rod mechanism, the sliding assembly moves a short stroke L3 to the left or right. Since the three-dimensional support frame 7 is fixed to the sliding assembly, the three-dimensional support frame 7 also moves a short stroke L3 to the left or right in synchronization with the sliding assembly. The mat placed in the mesh frame 72 of the three-dimensional support frame also moves back and forth in a short stroke left and right. During this left and right movement, the mat vibrates, further accelerating the evaporation of moisture on the mat surface (similar to the principle of drying wet clothes). Furthermore, the rate of air blowing through multiple mats is relatively accelerated, further improving the drying efficiency of the mats and shortening the drying time. The purpose of back and forth movement can be achieved by simply controlling the second motor 71 to rotate forward or reverse. The control is convenient. The speed of the sliding assembly movement can be controlled by the motor speed. No complex programming is required. The sliding assembly can be driven back and forth by indirect drive through the second motion mechanism. The power transmission is stable. The second motor and the first motor are controlled independently, 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.

[0068] See Figure 25 and Figure 26 , shows the blowing and drying device 3000 in the third embodiment, which mainly differs in the spatial three-dimensional support frame, specifically the different distances between the compartments 3001 of the net frame. The spacing between each compartment 3001 is relatively large, ranging from 50mm to 70mm, which is used for placing fewer mats. Each mat 3002 is placed in each compartment 3001, and the large spacing between them makes it 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 applicable to different scenarios.

[0069] The gas generator preferably adopts an air pump, a fan or a gas compressor. When the gas generator adopts a fan, for example, a cross-flow fan, a centrifugal fan, a comb fan, a cross-flow fan, a multi-blade fan, a mixed flow fan and a vortex fan can be used. The fan can adopt the fan structure in Panasonic's JP1977072908A, JP1984008679B2, JP1985059491B2, JP1983012694U, JP1988010319B2, JP1989008199B2, JP1993080600B2, JP1994056155B2, JP6051403B2, JP7213415B2 and other patents. The specific structure is discussed in detail in the patent and will not be repeated here. The gas generator for this project utilizes a centrifugal fan, which boasts a long lifespan of at least 3-5 years. This makes it suitable for harsh environments, particularly those in car washes with high moisture content. The outer rotor, dual-inlet air conditioner, purchased from Shanghai Yingda Fan Co., Ltd., boasts a flow rate of 1500-3000 cubic meters per second and an average speed of 1360 rpm. Its structure is based on that disclosed in patent CN211975442U.

[0070] See Figure 27 , return to see Figure 1 , is a logic control diagram for the blow-drying device of the present invention. The control unit communicates with the wind direction changing device, the reciprocating mechanism, the gas generator, the temperature sensor, the humidity sensor, and the heating module. The control unit can set the blow-drying time, air volume and pressure, the swing speed of the wind direction changing device, and the movement speed of the reciprocating mechanism. For example, if the setting is 8 minutes, the gas generator will operate within 8 minutes, the wind direction changing device will operate at the predetermined swing speed, and the reciprocating mechanism will operate at the predetermined movement speed. The hot air will pass through the wind direction changing device to blow-dry the mat, and the device will automatically stop after the time is up. The blow-drying device also includes a temperature sensor and a humidity sensor, which detect the temperature and humidity of the mat in real time. The detected temperature and humidity values ​​of the mat are transmitted to the control unit for comparison with temperature and humidity thresholds to determine the moisture and humidity on the mat surface, thereby controlling the start and stop of the blow-drying component 61.

[0071] The control unit can also control the start and stop of the gas generator, the output power of the heating module to control the hot air outlet temperature; the operation of the control unit is operated by an external controller, which can be an operation display panel and buttons on the upper surface of the housing 1 of the blowing and drying device 1000. The operation display panel 13 can display the air temperature, air volume and air pressure, and the blowing and drying set time. The power button 15 can operate the start and stop of the blowing and drying device 1000. A button or a knob 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 specified 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 scenarios, with strong applicability. The operation panel 13 uses a liquid crystal touch screen to display temperature and air volume values, which is intuitive and clear at a glance.

[0072] In addition, a dehumidification module can be installed in the drying box. When hot air is used to dry the mats in the three-dimensional support frame, the drying process easily generates fog, which makes the support frame relatively moist. The dehumidification module can remove the moisture in the support frame to prevent the moisture from affecting the subsequent drying of the mats and reducing the drying efficiency. A waterproof UV sterilizer is also installed inside the box 1 to sterilize the foot mats.

[0073] Return to Reference Figure 1 and Figure 2 The drying device 1000 also includes a closable 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 of the housing 1. The door is closed to prevent moisture from getting wet when standing in front of the mat during drying, and to prevent the mat from shaking and falling out. The hinged door is not shown in the figure and is conventional technology. A waterproof UV sterilizer is also installed inside the housing 1 to sterilize the mat.
