Description

TECHNICAL FIELD

[0001] The utility model relates to a car washer technical field, specifically, relate to a kind of dry device and the car washer with it. BACKGROUND

[0002] At present, after washing vehicle, the water stain on the surface of vehicle is usually relied on high-power fan to blow and dry vehicle, however, the above-mentioned drying method has the following two main shortcomings:

[0003] Shortcoming one: dead angle is difficult to cover, fan airflow is strong, but it is limited by the structure of vehicle body (i.e. the concave part formed by the window part relative to the vehicle body, the special concave design on the surface of part of vehicle models, the bottom of door, the wheel arch and other positions will have dead angle), water stain cannot be completely blown off (i.e. after airflow enters the concave part, wind pressure is greatly reduced, so that the water stain in the corner of dead angle cannot be blown out under the action of wind; or airflow cannot be blown to part of dead angle), and the above-mentioned dead angle becomes the "shelter" of water stain in the process of blowing and flowing, and water stain remaining in the dead angle will form water mark after drying (especially in the case of sunlight), and after washing car for many times, white scale (calcium and magnesium ions in water) will be gradually accumulated and formed in the corresponding dead angle.

[0004] Shortcoming two: the drying effect of large curved surface area is also poor, i.e. the large curved surface area such as roof and engine hood is easy to appear water mark and even scale deposition due to airflow dispersion in the process of flowing and great reduction of wind pressure.

[0025] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] In order to solve the problem of poor drying effect of the existing car washing machine drying method, the present application provides a drying device and a car washing machine with the same.

[0027] As shown in Figures 1 to 3 The drying device is arranged on the main body of the car washing machine and includes a first driving structure 10 and a drying assembly 20. The drying assembly 20 is drivingly connected with the first driving structure 10. The first driving structure 10 is used to drive the drying assembly 20 to rotate. The drying assembly 20 includes an elastic liquid absorption structure 21. During the rotation of the drying assembly 20, the elastic liquid absorption structure 21 collides with the outer surface of the vehicle to be elastically deformed and attached to the outer surface of the vehicle. The elastic liquid absorption structure 21 has a length L1 in a direction perpendicular to the rotation axis of the drying assembly 20. The rotation axis of the drying assembly 20 has a spacing L2 from the outer surface of the vehicle. The length L1 and the spacing L2 satisfy the following relationship: 5cm≤L1-L2≤20cm. Wherein, the elastic liquid absorption structure 21 is at least two. The at least two elastic liquid absorption structures 21 are arranged along the extension direction of the rotation axis of the drying assembly 20. The lengths L1 of the at least two elastic liquid absorption structures 21 are different.

[0028] The technical scheme is applied, the drying device arranged on the car washer main body comprises a first driving structure 10 and a drying assembly 20, the first driving structure 10 is used for driving the drying assembly 20 to rotate, the elastic liquid absorption structure 21 of the drying assembly 20 collides with the outer surface of the vehicle in the rotating process of the drying assembly 20 to be elastically deformed and be attached to the outer surface of the vehicle, thereby absorbing the liquid on the outer surface of the vehicle, the elastic liquid absorption structure 21 has a length L1 in the direction perpendicular to the rotating axis of the drying assembly 20, the rotating axis of the drying assembly 20 and the outer surface of the vehicle have a spacing L2, and the length L1 and the spacing L2 satisfy: 5cm≤L1-L2≤20cm. The elastic liquid absorption structure 21 is at least two, the at least two elastic liquid absorption structures 21 are arranged along the extension direction of the rotating axis of the drying assembly 20, and the lengths L1 of the at least two elastic liquid absorption structures are different. In this way, the embodiment actually adopts the drying mode to absorb the water on the outer surface of the vehicle and dry the vehicle, that is, in the rotating process of the drying assembly 20, the elastic liquid absorption structure 21 is elastically deformed in the process of colliding with the outer surface of the vehicle, and the deformed part is attached to the outer surface of the vehicle, is pressed and is further elastically deformed under the action of the elastic restoring force, so that the elastic liquid absorption structure 21 can be fully attached to the outer surface of the vehicle and absorb the water, better drying effect is achieved, and the length L1 can avoid that the end speed of the elastic liquid absorption structure 21 is too large, so that the collision is not too violent, the end part is not bounced off, the attachment degree to the outer surface of the vehicle is poor, and the drying effect is further improved. At the same time, the lengths L1 of the at least two elastic liquid absorption structures 21 can adapt to the shape of the outer surface of the vehicle (in general, the roof is narrower and the body is wider), so that each elastic liquid absorption structure 21 can match the outer surface of the vehicle to be dried, and the drying effect of the whole vehicle is further improved, thereby solving the problem of poor drying effect of the air drying mode of the car washer in the prior art, and improving the car washing experience of the user.

[0029] Specifically, the traditional blowing drying method has two defects, one is high energy consumption and high cost, that is, in order to pursue better drying effect, the current processing method is to prolong the running time of the high-power fan; the other is that the noise is large, that is, the large-power airflow has large noise, which affects the car washing experience of the customer (in fact, the noise on the spot will cause obstacles in making and receiving calls), and the drying method of the embodiment can greatly reduce the noise, and the overall drying efficiency is improved by 40%-60%, thereby shortening the waiting time of the customer, reducing the drying energy consumption and reducing the drying cost.

[0030] As Figure 1 and Figure 2As shown, the drying assembly 20 further comprises a mounting structure 22 for mounting the elastic liquid absorbing structure 21, and the first driving structure 10 is drivingly connected with the mounting structure 22 to drive the mounting structure 22 to rotate the elastic liquid absorbing structure 21. The elastic liquid absorbing structure 21 comprises a plurality of elastic liquid absorbing pieces 211 arranged along the extension direction and / or the circumferential direction of the mounting structure 22, and at least part of the elastic liquid absorbing pieces 211 are detachably connected with the mounting structure 22. In this way, the above arrangement makes the elastic liquid absorbing pieces 211 in the elastic liquid absorbing structure 21 detachable, i.e., the staff can adjust the number of the elastic liquid absorbing pieces 211 (adjust the total length of the plurality of elastic liquid absorbing pieces 211 along the extension direction of the mounting structure 22, adjust the arrangement density of the plurality of elastic liquid absorbing pieces 211 along the circumferential direction of the mounting structure 22), and the length L1 of the mounted elastic liquid absorbing piece 211 according to the vehicle specifications, to adapt to vehicles of different specifications and sizes, to ensure that the drying assembly 20 has excellent drying effect on vehicles of different specifications and sizes, and to improve the versatility of the drying device.

[0031] In the embodiment, the mounting structure 22 is a cylindrical structure, and the first driving structure 10 is rotatably connected with the end of the mounting structure 22 through other connecting structures such as a shaft coupling, i.e., the central axis of the mounting structure 22 coincides with the rotation axis of the drying assembly 20.

[0032] As shown in Figure 1 and Figure 2 The elastic liquid absorbing piece 211 has a belt-shaped portion 2111 for absorbing liquid and a first adhesive portion 2112 provided on the end of the belt-shaped portion 2111, and the outer circumferential surface of the mounting structure 22 is provided with a second adhesive portion 221, and the first adhesive portion 2112 and the second adhesive portion 221 are detachably bonded. In this way, the detachable bonding arrangement can reduce the operation difficulty of the staff and improve the disassembly efficiency of the elastic liquid absorbing piece 211.

[0033] In the embodiment, the first adhesive portion 2112 and the second adhesive portion 221 are actually magic tape structures.

[0034] Alternatively, the second adhesive portion 221 is the hook surface of the magic tape structure, which is in the form of a cylinder and is sleeved and fixed on the outer circumferential surface of the mounting structure 22, and the first adhesive portion 2112 is the loop surface of the magic tape structure, which is provided on the end of the belt-shaped portion 2111.

[0035] In the embodiment, the belt-shaped portion 2111 is actually a rectangular strip-shaped belt.

[0036] It should be noted that the structure and size of the strip-shaped part 2111 are not limited to this, and can be adjusted according to actual needs. For example, if there is a narrow-width recessed light bar on the surface of the vehicle, the elastic liquid-absorbing piece 211 can be replaced by an elastic liquid-absorbing piece 211 with a smaller width of the strip-shaped part 2111, so as to ensure that the strip-shaped part 2111 can enter the corresponding light bar recess.

[0037] In this embodiment, the strip-shaped part 2111 is made of a mixed fiber of PU and polyester.

[0038] In this embodiment, two elastic liquid-absorbing structures 21 are arranged along the extension direction of the mounting structure 22.

[0039] As shown in Figure 2 , the first adhesive 2112 in this embodiment is provided with two strip-shaped parts 2111 arranged along the extension direction of the mounting structure 22, and the two strip-shaped parts 2111 are attached to each other (there is basically no gap) to improve the liquid-absorbing effect.

[0040] For example, Figure 2 , the upper elastic liquid-absorbing structure 21 includes 14 columns of elastic liquid-absorbing pieces 211 arranged circumferentially along the mounting structure 22, each column of elastic liquid-absorbing pieces 211 includes four elastic liquid-absorbing pieces 211 arranged along the extension direction of the mounting structure 22 (the same below), the L1 of the upper elastic liquid-absorbing structure 21 is larger to adapt to the smaller width part from the roof to the vehicle body, and the L1 of the lower elastic liquid-absorbing structure 21 is larger to adapt to the larger width part of the vehicle body.

[0041] It should be noted that the number of elastic liquid-absorbing structures 21 is not limited to this, and can be further adjusted according to the design of the width of the outer periphery of the vehicle. For example, four, five, or more elastic liquid-absorbing structures 21 with different lengths L1 are used for corresponding matching to further improve the drying effect.

[0042] As shown in Figure 1 and Figure 3 , when the drying assembly 20 is located at the side of the vehicle, the drying device further includes a second driving structure 30, the second driving structure 30 is drivingly connected with the first driving structure 10, and the second driving structure 30 is used to drive the first driving structure 10 to drive the drying assembly 20 to move close to or away from the vehicle body. In this way, the automatic movement of the first driving structure 10 and the drying assembly 20 is realized through the second driving structure 30, so that the drying assembly 20 can avoid or contact the vehicle body to control the start or stop of the drying process, and then adapt to the overall car washing process of the car washing machine.

[0043] As shown in Figure 1 and Figure 3As shown, the second driving structure 30 comprises a connecting portion 31, a mounting portion 32 and a first driving member 33, the connecting portion 31 is arranged on the car washer main body. The mounting portion 32 is rotatably arranged on the connecting portion 31, and the first driving structure 10 is arranged on the mounting portion 32. The first driving member 33 is drivingly connected with the mounting portion 32 to drive the mounting portion 32 to rotate. In this way, the first driving structure 10 and the drying assembly 20 are actually adopted to realize the avoiding and contacting actions in a rotating mode, and the above-mentioned arrangement in the rotating mode enables the drying assembly 20, the mounting portion 32 and the first driving member 33 to completely move to the side of the vehicle when the vehicle is avoided, i.e., compared with the conventional avoiding arrangement in the telescopic mode, the drying assembly 20 does not occupy the space inside the car washer main body at all, i.e., the space for the vehicle to move inside the car washer main body is larger, which can adapt to the vehicle with a larger width, and thus the versatility of the car washer is improved.

[0044] In the embodiment, the connecting portion 31 comprises a columnar main body 311 and first and second mounting plates 312 and 313 arranged on the columnar main body 311. The first mounting plates 312 are two in number and are arranged in a spaced apart manner along the extension direction of the columnar main body 311 to form a first mounting space therearound, and the first mounting space is used for the at least partial extension of the car washer main body thereinto to realize the connection between the connecting portion 31 and the car washer main body by means of the fasteners arranged through the first mounting plates 312 and the car washer main body. The second mounting plates 313 are also two in number and are arranged in a spaced apart manner along the extension direction of the columnar main body 311 to form a second mounting space therearound, and the second mounting space is provided with a bearing member and a bearing seat.

[0045] Specifically, the mounting portion 32 is arranged in the form of a rectangular plate in the embodiment, and a rotating shaft structure is arranged on the end thereof rotatably connected with the connecting portion 31 to realize the rotating action of the mounting portion 32 through the rotating cooperation between the rotating shaft structure and the bearing member.

[0046] In the embodiment, a third mounting plate 321 is further arranged on the end of the mounting portion 32 away from the connecting portion 31, and the third mounting plate 321 is used for mounting (e.g., mounting through fasteners) the first driving structure 10.

[0047] In the embodiment, the first driving member 33 is a driving cylinder, and the two ends of the driving cylinder are rotatably connected with the connecting portion 31 and the mounting portion 32, respectively. The rotating axis of the mounting portion 32 and the rotating axis of any one of the driving cylinders are arranged in parallel with each other to realize the rotation of the mounting portion 32 through the telescopic movement of the driving cylinder.

[0048] In the embodiment, the first driving member 33 is an electric cylinder.

[0049] In other embodiments not shown in the drawings, when the drying assembly 20 is located above the vehicle, the drying device further comprises a third driving structure, which is drivingly connected with the first driving structure 10 and drives the first driving structure 10 to move up and down to drive the drying assembly 20 to move close to or away from the roof of the vehicle. In this way, the third driving structure is used to realize the up-and-down movement of the drying assembly 20, which can realize the avoidance or contact of the drying assembly 20 to the roof of the vehicle to control the start or stop of the drying process, thereby adapting to the overall car washing process of the car washing machine. On the other hand, the drying assembly 20 capable of up-and-down movement can further adapt to the slope of the roof (i.e., move with the slope of the roof) during the actual drying process of the roof, thereby ensuring that the drying assembly 20 has excellent drying effect on the roof.

[0050] In other embodiments not shown in the drawings, when the drying assembly 20 is located above the vehicle, the elastic liquid-absorbing structure 21 of the drying assembly 20 is at least three, including end elastic liquid-absorbing structures and a middle elastic liquid-absorbing structure located between the two end elastic liquid-absorbing structures, and the length L1 of the middle elastic liquid-absorbing structure is less than the length L1 of the end elastic liquid-absorbing structure. In this way, the above arrangement enables the drying assembly 20 to match the commonly seen arc-shaped roof, i.e., the middle elastic liquid-absorbing structure with smaller length L1 can match the convex part in the middle of the roof, and the end elastic liquid-absorbing structure with larger length L1 can match the edge part of the roof with lower height.

[0051] As shown in Figure 1 Figure 3 The first driving structure 10 comprises a reducer 11 and a second driving member 12, and the output end of the reducer 11 is connected with the mounting structure 22. The second driving member 12 is connected with the input end of the reducer 11. In this way, the reducer 11 can increase the output torque of the first driving structure 10 while reducing the overall output speed of the first driving structure 10, thereby ensuring that the elastic liquid-absorbing structure 21 can stably deform and match the surface of the vehicle during the collision process.

[0052] Optionally, the second driving member 12 is a servo motor.

[0053] Specifically, if the second driving member 12 is directly driven, when the elastic liquid-absorbing structure 21 cannot be elastically deformed enough (the drying assembly 20 is stuck), the worker can only increase the rotating speed of the second driving member 12, at which time the phenomenon of excessive rotating speed of the drying assembly 20 (i.e., excessive linear speed of the end of the belt-shaped part 2111, collision, and flying) is likely to occur. The present embodiment adds the reducer, so that the first driving structure 10 can output sufficient torque at a lower output rotating speed, thereby ensuring that the belt-shaped part 2111 can stably deform at a lower rotating speed, and effectively improving the vehicle drying effect of the drying device.

[0054] The drying device in the embodiment has at least the following advantages:

[0055] 1. The drying effect is more thorough. Compared with the fan blowing drying, the drying device in the embodiment can effectively reduce water marks and water stains on the surface of the vehicle, that is, the drying assembly 20 directly adsorbs water and calcium and magnesium ions in the water, and the residual water is basically none, and there is no white water stains and water stains formed by calcium and magnesium ions.

[0056] 2. There is basically no drying dead angle. By adjusting the length L1 of the plurality of elastic liquid suction structures 21, the surface, curved surface and recessed parts of the vehicle can be effectively dried.

[0057] 3. High universality. The elastic liquid suction structure 21 can be composed of different structures and sizes by disassembling and replacing the elastic liquid suction member 211, so as to adapt to the drying needs of vehicles of different specifications and sizes.

[0058] 4. The water stain removal efficiency is improved. The drying method of physical contact and rapid adsorption can adsorb more than 80% of the water film on the surface of the vehicle at one time, and the vehicle can be completely dried in a short running time.

[0059] 5. It can adapt to low-temperature environment drying. With the improvement of water stain removal efficiency, the possibility of water stain icing can be effectively avoided.

[0060] 6. The cost is effectively reduced. Compared with the fan blowing drying, the power consumption for drying the vehicle at one time is reduced by 30%-50%.

[0061] The embodiment also provides a car washing machine (not shown), which comprises a car washing machine body and at least two drying devices. The drying assembly 20 of at least one drying device is located on the side of the vehicle, and the drying assembly 20 of at least another drying device is located above the vehicle. The drying assembly 20 is the above-mentioned drying device.

[0062] The drying device in the embodiment can be installed on the tunnel machine of the car washing machine main body and located behind the fan of the tunnel machine or independently installed on the gantry end of the car washing machine main body, when the sensor for detecting the start of the dry car operation senses the presence of the vehicle at the corresponding position, the signal is fed back to the PLC control system, the corresponding first driving structure 10 and the second driving structure 30 of the drying assembly 20 located on the side of the vehicle are started, the corresponding first driving structure 10 and the third driving structure of the drying assembly 20 located above the vehicle are started, and the vehicle is started to be dried, after the whole vehicle body passes through the drying assembly 20, the sensor senses that the vehicle at the corresponding position disappears, the sensor feeds the signal back to the PLC control system, the first driving structure 10 corresponding to the drying assembly 20 located on the side of the vehicle is stopped, the second driving structure 30 drives the drying assembly 20 to reset, and the first driving structure 10 corresponding to the drying assembly 20 located above the vehicle is stopped, and the third driving structure drives the drying assembly 20 to reset.

[0063] From the above description, it can be seen that the above-mentioned embodiments of the utility model realize the following technical effects:

[0064] The drying device arranged on the car washer main body comprises a first driving structure and a drying assembly, the first driving structure is used for driving the drying assembly to rotate, and the elastic liquid absorbing structure of the drying assembly will collide with the outer surface of the vehicle during the rotation of the drying assembly to be elastically deformed and adhere to the outer surface of the vehicle, thereby absorbing the liquid on the outer surface of the vehicle, the elastic liquid absorbing structure has a length L1 in a direction perpendicular to the rotation axis of the drying assembly, the rotation axis of the drying assembly and the outer surface of the vehicle have a spacing L2, and the length L1 and the spacing L2 satisfy: 5cm≤L1-L2≤20cm. Wherein, the elastic liquid absorbing structure is at least two, at least two elastic liquid absorbing structures are arranged along the extension direction of the rotation axis of the drying assembly, and the lengths L1 of the at least two elastic liquid absorbing structures are different. In this way, the water liquid on the outer surface of the vehicle is actually absorbed and dried by the drying method, that is, during the rotation of the drying assembly, the elastic liquid absorbing structure will be elastically deformed in the process of colliding with the outer surface of the vehicle, and the deformed part will adhere to the outer surface of the vehicle, be extruded and further elastically deformed under the action of elastic restoring force, so as to fully adhere to the outer surface of the vehicle, absorb water liquid and achieve better drying effect, and the length L1 can avoid that the end line speed of the elastic liquid absorbing structure is too large, so as to avoid that the deformed part is bounced off and the adhesion degree to the outer surface of the vehicle is poor due to too violent collision, and the drying effect is further improved. At the same time, the length L1 of the at least two elastic liquid absorbing structures can adapt to the shape of the outer surface of the vehicle (commonly, the roof is narrower and the body is wider), so as to ensure that each elastic liquid absorbing structure can match the outer surface of the vehicle to be dried, and the drying effect of the whole vehicle is further improved, thereby solving the problem of poor drying effect of the drying method of the car washer in the prior art, and improving the car washing experience of the user.
