Description
Technical Field
[0001] The utility model relates to the technical field related to clothes drying machines, in particular to an air outlet structure and a clothes drying machine. Background Art
[0002] Considering the air volume requirements, the existing clothes drying fans usually choose centrifugal fans with larger air volume;
[0003] The effective air outlet of the centrifugal fan is small. When the air outlet area is large, the air volume is concentrated and the air volume at other positions of the air outlet is extremely small. When the product has an application requirement of a long air outlet, uneven air outlet will result. Utility Model Content
[0004] Based on this, it is necessary to provide an air outlet structure and a clothes drying machine with an air volume that can meet the demand and have a better air outlet effect to address the problem that the current centrifugal fans result in poor air outlet effect and uneven air outlet.
[0005] The present application first provides an air outlet structure, including a box body, wherein an air duct and a plurality of fans are arranged in the box body, and an air inlet and an air outlet are opened on the box body;
[0006] The air inlet end of each of the fans faces the air inlet, the air outlet end of each of the fans faces the air inlet end of the air duct, and the air outlet end of the air duct faces the air outlet;
[0007] A plurality of partitions are arranged inside the air duct to divide the air duct into a plurality of sub-air ducts, and each of the sub-air ducts has an air inlet end facing the fan and an air outlet end facing the air outlet.
[0008] In one embodiment, each of the fans is located on the same side of the box along the width direction relative to the air duct.
[0009] In one embodiment, the fans are arranged side by side along the length direction of the box, and a PTC heating element is also provided in the box between the fans and the air duct, and the projection of the PTC heating element along the axis direction of the fan covers each fan.
[0010] In one embodiment, the area of the air inlet end of the air duct is smaller than the area of the air outlet end.
[0011] In one embodiment, the area of the air inlet end of each sub-air duct is smaller than the area of its own air outlet end.
[0012] In one of the embodiments, the ratio of the total areas of the sub-air duct inlet ends corresponding to any two of the fans is in the range of 0.75 to 1.25, and the ratio of the total areas of the sub-air duct outlet ends corresponding to any two of the fans is in the range of 0.75 to 1.25.
[0013] In one embodiment, the air outlet end of the air duct is in an elongated strip shape, the length of which is greater than half of the length of the box and less than or equal to the length of the box, and the air outlet end of the air duct is located at the center of the bottom surface of the box along the width direction.
[0014] In one of the embodiments, each of the partitions divides the air duct into a plurality of sub-air ducts along the length direction of the box.
[0015] In one embodiment, the fan is an axial flow fan and / or a mixed flow fan.
[0016] A second aspect of the present application provides a clothes drying machine, comprising a clothes drying machine main unit and the above-mentioned air outlet structure, wherein the length of the air outlet is greater than half of the length of the box body and is less than or equal to the length of the box body.
[0017] In one of the embodiments, the air outlet passes through the centroid of the plane shape where the air outlet is located.

[0019] The above-mentioned air outlet structure divides the air duct into multiple sub-air ducts, and corresponds each fan to one or more sub-air ducts, so that the air duct partitions form multiple air supply areas corresponding to each fan. On the one hand, it can manage the air supply capacity of each fan according to actual needs to ensure uniform air outlet, thereby improving the versatility and overall air outlet effect of the air outlet structure of the present application. On the other hand, each sub-air duct has a smaller air supply capacity than the air duct, so that even a fan with relatively weak air supply capacity can meet the air supply needs of the sub-air duct.

[0030] Please combine Figure 1 as well as Figure 2 As shown, the present application first provides an air outlet structure, a box body 10, an air duct 30 and a plurality of fans 20 are arranged in the box body 10, and an air inlet and an air outlet are opened on the box body 10; the air inlet end of each fan 20 faces the air inlet, the air outlet end of each fan 20 faces the air inlet end of the air duct 30, and the air outlet end of the air duct 30 faces the air outlet; a plurality of partitions 31 are arranged inside the air duct 30 to divide the air duct 30 into a plurality of sub-air ducts 32, and each sub-air duct 32 has an air inlet end facing the fan 20 and an air outlet end facing the air outlet.
[0031] By dividing the air duct 30 into a plurality of sub-ducts 32 and corresponding each fan 20 to one or more sub-ducts 32, the air duct 30 is partitioned into a plurality of air supply areas corresponding to each fan 20. On the one hand, the air supply capacity of each fan 20 can be zoned and managed according to actual needs to ensure uniform air output, thereby improving the versatility of the air outlet structure of the present application and the overall air outlet effect. On the other hand, each sub-duct 32 has a smaller air supply capacity than that required by the air duct 30, so that even a fan 20 with relatively weak air supply capacity can meet the air supply demand of the sub-duct 32.
[0032] Specifically, each fan 20 corresponds to two or three sub-ducts 32; of course, the corresponding number of fans 20 and sub-ducts 32 can also be matched in other ways, for example, each fan 20 corresponds to one sub-duct 32, or each fan 20 corresponds to more than three sub-ducts 32. As long as the air output of each sub-duct 32 is uniform and the air volume meets the air supply demand, this application does not limit it.
[0033] It is worth mentioning that the centrifugal fans commonly used in clothes drying machines currently take up a large space and can usually only be installed with top or bottom air intake. Among them, the top air intake has a large air intake resistance due to the small gap between the machine and the top of the balcony, which may affect the air outlet effect of the clothes drying machine. The bottom air intake, on the one hand, may affect the air outlet effect due to interference between the air inlet and outlet, and on the other hand, the aesthetics is relatively poor.
[0034] In this regard, in some embodiments, the fan 20 is an axial flow fan.
[0035] It is not difficult to understand that by selecting an axial flow fan as the air supply fan, the volume of the axial flow fan is smaller than that of the centrifugal fan, so it can be set on the side of the box 10, thereby ensuring that the air inlet resistance at the air inlet end of the axial flow fan is relatively small while avoiding interference between the inlet and outlet airflows, thereby effectively improving the air outlet effect of the air outlet structure of the present application; in addition, the air supply capacity of the axial flow fan is weaker than that of the centrifugal fan, and the provision of multiple axial flow fans in the present application can ensure that the overall air supply capacity meets the requirements.
[0036] In some other embodiments, the fan 20 may also be a mixed flow fan, or an axial flow fan and a mixed flow fan may be used at the same time. As long as the fan 20 is smaller in size and occupies less space than a centrifugal fan, the present application does not make any further limitations.
[0037] In some embodiments, a PTC heating element 40 is provided between the fan 20 and the air duct 30 for heating the outlet air flow to improve the drying capacity of the air outlet structure of the present application.
[0038] In some embodiments, the air inlet end of the air duct 30 also has a downward opening to facilitate the installation of the fan 20 and the PTC heating element 40.
[0039] In some embodiments, each fan 20 is located on the same side of the box 10 along the width direction relative to the air duct 30; so that each fan 20 is located on the same side of the box 10, and the other side of the box 10 can be left empty and used to accommodate other structures such as a power board and a winding device, thereby effectively improving the space utilization inside the box 10.
[0040] Please combine Figure 1 as well as Figure 3 As shown, in some embodiments, the fans 20 are arranged side by side along the length direction of the housing 10 , and the projection of the PTC heating element 40 along the axis direction of the fans 20 covers the fans 20 .
[0041] By arranging the fans 20 side by side, only one PTC heater 40 is required to meet the airflow heating requirements of each fan 20. Compared with separately arranging multiple smaller PTC heaters 40, arranging one PTC heater 40 has lower costs and installation difficulty.
[0042] Preferably, three fans 20 are arranged side by side in the box body 10 along the length direction of the box body 10; of course, in some other embodiments, the fans 20 may also be other numbers, as long as the air supply capacity can meet the actual needs, and the present application does not make further limitations here.
[0043] Please combine Figure 1 , Figure 2 as well as Figure 3 As shown, in some embodiments, the area of the air inlet end of the air duct 30 is smaller than the area of the air outlet end; the air outlet area is increased to meet the air outlet needs of a larger area.
[0044] Specifically, the air duct 30 is horn-shaped as a whole.
[0045] Please combine Figure 1 , Figure 2 as well as Figure 3 As shown, in some embodiments, the ratio of the total areas of the air inlet ends of the sub-air ducts 32 corresponding to any two fans 20 ranges from 0.75 to 1.25, and the ratio of the total areas of the air outlet ends of the sub-air ducts 32 corresponding to any two fans 20 ranges from 0.75 to 1.25.
[0046] This ensures that the air supply areas corresponding to the various fans 20 are relatively uniform, thereby ensuring that the overall air outlet effect of the air outlet structure of the present application is relatively uniform.
[0047] Preferably, the total areas of the air inlet ends of the sub-air ducts 32 corresponding to any two fans 20 are equal, and the total areas of the air outlet ends of the sub-air ducts 32 corresponding to any two fans 20 are equal.
[0048] It should be noted that the above-mentioned embodiment is aimed at the situation where the fans 20 have the same power and the same air output capacity. If the air output capacities of different fans 20 are different, the air supply area corresponding to the fan 20 is proportional to its air output capacity.
[0049] In some embodiments, the area of the air inlet end of each sub-air duct 32 is smaller than the area of its own air outlet end.
[0050] Please combine Figure 1 as well as Figure 3 As shown, in some embodiments, the air outlet end of the air duct 30 is in a long strip shape, the length of the air outlet end of the air duct 30 is greater than half of the length of the box 10, and is less than or equal to the length of the box 10, and the air outlet end of the air duct 30 is located at the center of the bottom surface of the box 10 along the width direction.
[0051] Preferably, the length of the air outlet end of the air duct 30 is equal to the length of the box body 10, that is, the air outlet end of the air duct 30 extends to the two ends of the bottom surface of the box body 10 along the length direction, so that the effective air outlet area of the air outlet structure of the present application completely covers the bottom of the equipment along the length direction to avoid the existence of dead corners for air outlet; in addition, the centrally placed strip air outlet has a relatively beautiful appearance and a more uniform air outlet effect.
[0052] In some embodiments, each partition 31 divides the air duct 30 into multiple sub-air ducts 32 along the length direction of the box body 10; to ensure that the long air outlet of the air duct 30 can be divided into multiple sub-air ducts 32, and different fans 20 are responsible for supplying air, so as to increase the air outlet uniformity of the long air outlet while meeting the air supply requirements of the long air outlet.
[0053] A second aspect of the present application provides a clothes drying machine, including a clothes drying machine host and the above-mentioned air outlet structure, wherein the length of the air outlet is greater than half of the length of the box 10 and is less than or equal to the length of the box 10.
[0054] Specifically, the box 10 can be the outer shell of the clothes drying machine host, or can be arranged inside the clothes drying machine host. In the latter case, the air outlet of the box 10 is connected to the air outlet end of the clothes drying machine host.
[0055] In the above embodiment, since the air outlet is matched with multiple sub-air ducts 32 through the multi-fan 20, air flow is distributed between each sub-air duct 32, so that air flow is blown out at all places on the long strip air outlet formed by extending each sub-air duct 32.
[0056] It should be noted that the present application does not impose any specific restrictions on the shape of the air outlet. Figure 1 In the illustrated embodiment, the air outlet is rectangular, and the air outlet end of each sub-air duct 32 is regarded as an air outlet unit. The air outlet is actually composed of a plurality of air outlet units arranged in sequence.
[0057] As an alternative implementation, the box body 10 may also have a plurality of air outlets, each of which includes at least one air outlet unit, and the plurality of air outlets may be continuous or separated from each other.
[0058] As another alternative implementation, the air outlet units may be arranged on the surface of the housing 10 to form a circular or arc-shaped array to meet the needs of different users.
[0059] In some embodiments, a water replenishing device and a steam generating device are also provided in the main body of the clothes drying machine. The water replenishing device is connected to the steam generating device, and the steam outlet of the steam generating device is connected to the air duct 30; the water replenishing device includes a water tank and a water pump, and the water pump is connected to the water tank and the steam generating device to supply water to the steam generating device, and the steam generating device can generate steam to achieve a care effect.
[0060] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0061] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
