Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of clothes drying machines, and in particular to a wind channel structure and a clothes drying machine. BACKGROUND

[0002] Current electric clothes drying machines on the market generally use a grid constant air outlet or a guide vane with a swing leaf to achieve rapid drying of clothes in the design of the drying function. However, both designs have certain limitations in actual application.

[0003] The design using a grid constant air outlet has a relatively fixed and limited air outlet range, which is difficult to uniformly and comprehensively cover every corner of the entire piece of clothing. This often leads to poor drying effect in some areas of the clothing, while other areas may be damaged due to over-drying, affecting the overall drying effect and service life of the clothing.

[0004] In comparison, the design of the swing-leaf guide vane, although it increases the air outlet range to some extent, seems to be able to dry the clothes more uniformly, but in fact it takes a long time to swing and expand the air outlet range. In this process, the heat on the surface of the clothing dissipates quickly, not only reducing the drying efficiency, but also increasing energy consumption and user waiting time due to long waiting time.

[0005] In summary, the existing electric clothes drying machines still need to be improved and optimized in the design of the drying function to better meet the needs of users for efficient and uniform drying of clothes. CONTENT OF THE INVENTION

DETAILED DESCRIPTION

[0036] In order to make the technical problems solved in the present application, the technical solutions adopted and the technical effects achieved more clear, the technical solutions of the embodiments of the present application are further described in detail below. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0037] In the description of the present application, unless otherwise explicitly specified and limited, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0038] In the present application, unless otherwise explicitly specified and limited, the first feature "on" or "under" the second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the first feature "on", "above" and "above" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "under", "below" and "below" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0039] The current market electric drying machine, in the design of drying function, generally uses grid constant air outlet or air deflector with swing leaf to realize the rapid drying of clothes. However, both of these two designs have certain limitations in actual application.

[0040] The design of the grid constant air outlet has a relatively fixed and limited air outlet range, which is difficult to uniformly and comprehensively cover every corner of the entire piece of clothing. This often leads to poor drying effect in some areas of the clothing, while other areas may be damaged due to over-drying, affecting the overall drying effect and service life of the clothing.

[0041] In contrast, the design of the swing-leaf air deflector, although increasing the swing range of the air outlet to some extent, seems to be able to dry the clothing more uniformly, but in fact it needs a longer time to swing and expand the air outlet range. In this process, the heat loss rate of the surface of the clothing is faster, not only reducing the drying efficiency, but also increasing the energy consumption and waiting time of the user due to long waiting time.

[0042] In summary, the existing electric clothes drying machine still needs to be improved and optimized in the design of the drying function to better meet the user's demand for efficient and uniform drying of clothes.

[0043] To achieve the above purpose, the embodiment of the present application provides a wind channel structure, which comprises a wind channel main body 31 and an air guide piece 32, the wind channel main body 31 is provided with an air inlet 313 and an air outlet 314; the air guide piece 32 is arranged at the air outlet 314, the air guide piece 32 comprises at least one air deflector 321, the air deflector 321 is arranged obliquely relative to the median vertical plane of the air outlet 314, so as to guide part of the airflow output by the air outlet 314 to deviate from the direction of the median vertical plane of the air outlet 314, and expand the air outlet range.

[0044] Wherein, the air guide piece 32 is arranged at the air outlet 314 of the wind channel main body 31, specifically opposite to the air outlet 314, according to the application requirement, the air guide piece 32 can be arranged in the wind channel main body 31 or outside the wind channel main body 31.

[0045] The median vertical plane of the air outlet 314 refers to the median vertical plane of the plane where the two opposite long sides of the air outlet are located. Under normal circumstances, the area of the air outlet 314 outward air outlet is in the shape of a horn with the median vertical plane as the center. The air deflector 321 arranged obliquely relative to the median vertical plane realizes the outward expansion of part of the airflow, and further realizes the purpose of expanding the air outlet range.

[0046] Therefore, the wind channel structure provided by the embodiment can expand the air outlet range on the basis of the original, to meet the use requirement of larger air outlet range. It should be noted that the wind channel structure of the embodiment can be applied to but not limited to the clothes drying machine product.

[0047] When the air duct structure 30 of the embodiment is applied to the clothes drying machine, the air flow of the clothes drying machine can be optimized and guided, the drying range is expanded, and the clothes hung on the drying machine can be evenly dried. In addition, the air outlet of the clothes drying machine does not need to swing, so that the problem of rapid heat loss on the surface of the clothes caused by waiting for the swing of the swing leaf can be effectively avoided, and the drying efficiency is improved.

[0048] In order to better understand the embodiment, the structure of the clothes drying machine will be explained first.

[0049] Combined with the above Figure 1 , the current clothes drying machine includes a clothes drying machine 10 and a drying rack 20. The drying rack 20 is suspended below the clothes drying machine 10, and the drying mechanism is installed in the clothes drying machine 10. When the drying mechanism is started, hot air is blown downward to dry the clothes. In order to consider the folding function of the clothes drying machine (when folding, the drying rack 20 will be wrapped around the outer periphery of the clothes drying machine 10), the two drying rods 21 on both sides of the drying rack 20 will be biased outward relative to the drying mechanism in the clothes drying machine 10, that is, in fact, the drying mechanism blows hot air downward, and the central region of the hot air will be located on the inner side of the drying rod 21. Although the hot air will diffuse after being blown downward, the clothes are vertically hung on the drying rod 21, and the clothes located on the outer side of the drying rod 21 will obviously contact less air, and even there may be a situation that the outer side of the clothes does not contact the hot air at all, which is an important factor that causes uneven drying effect.

[0050] As shown in Figures 2-5 , the air duct structure 30 provided by the embodiment includes an air duct body 31 and a wind guide 32. The air duct body 31 is provided with an air inlet 313 and an air outlet 314. The air outlet 314 is arranged on the bottom side of the air duct body 31. The wind guide 32 is arranged below the air outlet 314. At least one wind guide plate 321 extends in a direction parallel to the length of the drying rod 21. The side close to the center of the clothes drying machine is the inner side, and the side away from the center of the clothes drying machine is the outer side. At least one wind guide plate 321 is arranged from top to bottom and outwardly inclined to guide part of the air flow outwardly.

[0051] The air duct structure 30 of the embodiment is particularly applied to the drying mechanism in the clothes airing main machine 10, and is connected with a fan, an electric heater and the like in application, and air is heated by the electric heater under the driving of the fan, and then is transported into the air duct main body 31 through the air inlet 313 of the air duct main body 31, and then is blown downward through the air outlet 314 at the bottom. The air guide piece 32 is further arranged below the air outlet 314, the air guide piece 32 has one or more air guide plates 321, and at least one of the air guide plates 321 is inclined downward and extends outward from top to bottom, so that when the air flow above blows against the surface of the air guide plate 321, the air guide plate 321 will guide the hot air to blow outward obliquely, which is equivalent to expanding the range of horizontal outward air outlet, and thus the clothes hung on the airing rod 21 below can also effectively contact the air flow on the outer side, and the purpose of improving the uniformity of drying is achieved.

[0052] The air duct structure 30 provided by the embodiment can be highly fitted into the existing full-folding clothes airing machine, the inclined air guide plate 321 is arranged therein, and when working, the hot air is effectively guided to the outer side of the clothes, so that each part of the clothes can be uniformly contacted with the hot air, and the problem of uneven drying in the conventional design is solved. The inclined air guide plate 321 of the embodiment directly expands the coverage range of the hot air, without swinging, reduces the additional time consumed due to the swing of the swing leaf, reduces the heat loss, thereby accelerating the drying speed and improving the overall drying efficiency.

[0053] The optimized air duct structure 30 not only improves the drying effect, but also shortens the drying cycle, reduces the waiting time of the user, maintains the good drying state of the clothes, prolongs the service life of the clothes, and improves the user satisfaction.

[0054] In an embodiment, the air guide plate 321 located at the outermost side is an outer air guide plate 3211, the outer air guide plate 3211 is arranged obliquely downward and outward from top to bottom, and the downward extension line of the outer air guide plate 3211 passes through the outside of the central axis of the corresponding airing rod 21 below.

[0055] The air guide plate 321 located at the outermost side of the air duct structure 30 is specially designed as the outer air guide plate 3211, which is obliquely arranged downward and outward from top to bottom, which ensures that the hot air can be effectively guided to the outer side of the clothes when blown out. It is particularly worth noting that the downward extension line of the outer air guide plate 3211 will pass through the outside of the central axis of the corresponding airing rod 21 below, which means that the hot air not only covers the clothes area directly below the airing rod 21, but also reaches the edge part of the clothes on the outer side, which is difficult to dry in the conventional design.

[0056] The outer guide air baffle 3211 is arranged, and a downward extension line of the outer guide air baffle 3211 passes outside of a central axis of the corresponding drying rod 21 below, so that hot air can be effectively guided and covered to an outer side area of the clothes hung, and the function of quickly drying the whole clothes is realized.

[0057] In an embodiment, as shown in Figure 6 A vertical distance between a bottom edge of the outer guide air baffle 3211 and an upper surface of the drying rod 21 is L1, a horizontal distance between the outer side surface of the drying rod 21 and the inner side surface of the drying rod 21 is L2, a horizontal width of the drying rod 21 is L, and an included angle between the outer guide air baffle 3211 and a vertical plane is ∠A, wherein tan A>(L2+L / 2) / L1.

[0058] Specifically, tan A>(L2+L / 2) / L1, so that the downward extension line of the outer guide air baffle 3211 passes outside of the central axis of the corresponding drying rod 21 below, and the function of quickly drying the whole clothes is realized.

[0059] In an embodiment, the air guide baffle 321 includes at least two air guide baffles, and the innermost air guide baffle 321 is an inner guide air baffle 3212, which is arranged to be inclined inward from top to bottom, so as to guide part of the air flow inwardly.

[0060] The inner guide air baffle 3212 is inclined inward from top to bottom, which ensures that the hot air can be effectively guided to the inner side area of the clothes when the hot air is blown out. In combination with the design of the inner guide air baffle 3212 and the outer guide air baffle 3211, the hot air can be effectively guided to the inner side and the outer side of the clothes, so that the drying uniformity of each part of the clothes is ensured.

[0061] In an embodiment, as shown in Figure 6 An included angle between the inner guide air baffle 3212 and a vertical plane is ∠B, and 0<∠B<5°.

[0062] Specifically, according to the foregoing analysis, the air outlet 314 of the top air duct body 31 is actually horizontally offset inward relative to the drying rod 21 below, so that the inward inclination angle ∠B of the inner guide air baffle 3212 is controlled to be within 5°, which can avoid that too much hot air guided inward deviates from the inner side area of the clothes, and reduce the problem of heat waste.

[0063] In an embodiment, the air guide member 32 includes a connecting end plate 322, and the end of the air guide baffle 321 is connected with the connecting end plate 322; the air duct body 31 is provided with two mounting end plates 3111 extending downward relative to the air outlet 314, and the connecting end plate 322 is connected with the mounting end plates 3111, so as to realize the mounting of the air guide member 32.

[0064] Through the design of the connecting end plate 322 and the mounting end plate 3111, the air guide piece 32 can be firmly fixed on the air duct body 31, improving the stability of the entire air duct structure 30; the design of the mounting end plate 3111 makes the installation process of the air guide piece 32 more convenient, reducing the installation difficulty and cost. When it is necessary to clean, maintain or replace the air guide piece 32, the connecting piece between the connecting end plate 322 and the mounting end plate 3111 can be disassembled, and the air guide piece 32 can be easily disassembled and reinstalled.

[0065] Specifically, when a plurality of air guide plates 321 are provided, the ends of each air guide plate 321 are connected with the connecting end plate 322, and the connecting end plate 322 can maintain the relative stability between the air guide plates 321. In addition, in order to further improve the stability, reinforcing rib plates can also be connected between the air guide plates 321 for reinforcement.

[0066] Specifically, the air guide plate 321 can be at least one, two, three or more, and each air guide plate 321 can guide the hot air at different angles to achieve the purpose of effectively expanding the drying area.

[0067] In an embodiment, the connecting end plate 322 and the mounting end plate 3111 are rotatably connected to adjust the inclination angle of the air guide plate 321.

[0068] The connecting end plate 322 and the mounting end plate 3111 are rotatably connected, such as hinges, rotating buckles, etc., so that the air guide plate 321 can adjust its inclination angle within a certain range. By adjusting the relative angle between the connecting end plate 322 and the mounting end plate 3111, the inclination angle of the air guide plate 321 can be easily changed, thereby achieving precise control of the hot air guiding direction. For example, the user can flexibly adjust the inclination angle of the air guide plate 321 according to the material, shape, size and number of clothes, etc., to obtain the best drying effect, thereby improving the user experience.

[0069] In specific implementation, in order to ensure that the air guide plate 321 can maintain a stable inclination angle after adjustment, a corresponding locking mechanism can be designed, such as bolts, buckle locks, etc., to firmly lock the connecting end plate 322 and the mounting end plate 3111 at the required angle.

[0070] In specific implementation, since the key purpose of the air guide piece 32 of the present embodiment is to at least guide part of the hot air to be inclined and blown outwards to dry the outer part of the clothes, at least one air guide plate 321 needs to be inclined from top to bottom and outward during the process of adjusting the inclination angle of the air guide piece 32. Since the air outlet 314 of the air duct body 31 is relatively biased inwardly to the drying rod 21, it is not necessary to have an air guide plate 321 inclined from top to bottom and inwardly.

[0071] In an embodiment, as shown in Figure 4 The inner side of the mounting end plate 3111 is provided with at least two clamping positions 3112, and the connecting end plate 322 is provided with clamping blocks 323 matched with the clamping positions 3112. The clamping blocks 323 are matched with different clamping positions 3112 to position the air deflectors 321 at different angles.

[0072] Through the matching design of the clamping positions 3112 and the clamping blocks 323, the user can conveniently adjust the angle of the air deflectors 321 without complex operations or tools. The precise matching of the clamping positions 3112 and the clamping blocks 323 ensures that the air deflectors 321 can stably stay at the required angle, avoiding the problem of affecting the drying effect due to angle deviation.

[0073] As shown in Figure 7 When the clamping blocks 323 are matched with the first clamping positions 3112, the air deflectors 321 on the inner side are inclined to extend inward, and the air deflectors 321 on the outer side are inclined to extend outward, so at this time the air deflectors 321 on the inner side can serve as inner guide air deflectors 3212, and the air deflectors 321 on the outer side serve as outer guide air deflectors 3211.

[0074] As shown in Figure 8 When the clamping blocks 323 are matched with the second clamping positions 3112, the air deflectors 321 on the inner side are also inclined to extend outward, so at this time they do not serve as inner guide air deflectors 3212, in other words, there are no inner guide air deflectors 3212 in this state.

[0075] In an embodiment, the air deflecting member 32 can be rotated and adjusted relative to the mounting end plate 3111 within an angle range of 15° to 25°.

[0076] The adjustment range of 15° to 25° enables the air deflecting member 32 to be applicable to more types of clothes and drying needs, improving the flexibility and adaptability of the air duct structure 30.

[0077] In an embodiment, the width of the clamping positions 3112 is greater than the width of the clamping blocks 323, so that the air deflectors 321 can freely swing within a certain angle relative to the air duct body 31.

[0078] Specifically, the width of the clamping positions 3112 is greater than the width of the clamping blocks 323, which means that the clamping blocks 323 can freely move within the limiting range of the clamping positions 3112, i.e., the clamping positions 3112 and the clamping blocks 323 limit the rotation of the air deflectors 321, but not completely, so that the air deflectors 321 can freely swing within the limited angle range. The air deflectors 321 are designed to freely swing, which can achieve a larger range of blowing, but the swing amplitude is controlled within a smaller range to ensure timely replenishment of heat.

[0079] Optionally, the angle at which the air deflector can freely rotate relative to the air duct body is 5-10°.

[0080] The angle range can avoid heat loss.

[0081] In an embodiment, the air duct body 31 comprises an air duct pipe 311 and a connecting pipe 312, the air duct pipe 311 is arranged along the length direction parallel to the drying rod 21, the connecting pipe 312 is connected to one side of the air duct pipe 311, the air inlet 313 is formed on the side of the connecting pipe 312 away from the air duct pipe 311, and the air outlet 314 is formed on the bottom side of the air duct pipe 311.

[0082] In a specific implementation, the air duct body 31 needs to be connected with the fan, and the connecting pipe 312 extending laterally is arranged on the side, and the air inlet 313 is arranged on one side of the connecting pipe 312, that is, the connecting pipe 312 can be used as a connection with the fan. This structure can realize the horizontal arrangement and connection of the fan and the air duct body 31, which can effectively reduce the height dimension of the entire drying mechanism in the vertical direction, and is more convenient for installation in the clothes drying main machine 10.

[0083] In order to facilitate observation of the internal structure of the air duct body 31, the air duct body 31 shown in the figure is only the base part, and in actual application, a top cover needs to be arranged on the top side of the air duct body 31 to seal, so that the hot air entering the air duct pipe 311 can be blown downward through the air outlet 314 below.

[0084] In an embodiment, the bottom plate of the connecting pipe 312 extends upwardly and obliquely from the side where the air inlet 313 is located to the side where the air duct pipe 311 is located.

[0085] In this structure, the air inlet 313 can have sufficient height in the vertical dimension to facilitate connection with the fan. The bottom plate of the connecting pipe 312 extends upwardly and obliquely, which can guide the hot air to the top side area of the air duct pipe 311, and the area is far away from the bottom air outlet 314, so that the hot air can more evenly fill the entire air duct pipe 311, and uniform air outlet along the length direction of the air duct pipe 311 is realized.

[0086] On the other hand, a clothes drying machine is provided, comprising the above-mentioned air duct structure 30.

[0087] Specifically, the clothes drying machine of the embodiment comprises a clothes drying main machine 10 and a drying rack 20 suspended below the clothes drying main machine 10. The clothes drying main machine 10 is provided with a drying mechanism, and the drying mechanism comprises a fan, an electric heater and the above-mentioned air duct structure 30.

[0088] Based on the air duct structure 30 of the embodiment, the clothes drying machine of the embodiment can expand the coverage range of the hot air, without swinging, reducing the additional time consumed by the swing of the swingable leaf, reducing the heat loss, thereby accelerating the drying speed and improving the overall drying efficiency.
