Description

Technical Field

[0001] This application relates to the field of home appliance technology, specifically providing a clothing processing device. Background Technology

[0002] Currently, with the aim of further facilitating users' lives, household laundry equipment is further divided into washing machines, dryers, or washer-dryer combos.

[0003] Taking a clothes dryer as an example, a clothes dryer includes a drum for holding clothes and a circulating air duct connected to the drum. As the air inside the drum passes through the circulating air duct, it gains heat from a heat source, its temperature rises, and its relative humidity decreases, resulting in hot, dry air that flows back into the drum to absorb moisture from the clothes. After absorbing moisture from the clothes, the relative humidity of the air increases, becoming a hot, humid airflow. This hot, humid air flows into the air duct and is cooled and dehumidified at the evaporator, forming low-temperature, dry air. This dehumidified, low-temperature, dry air then flows back through the heat source, absorbing heat and becoming hot air again to dry the clothes inside the drum once more.

[0004] However, for the entire circulation process of airflow, its trajectory needs to be constantly changed to form a closed loop path. Especially in the "rear air duct" position of the dryer, the airflow needs to move vertically upward along the rear air duct and then turn to enter the drum in a horizontal direction. This will inevitably form vortices at the turning point of the airflow, which will not only cause pressure loss and flow noise, but also affect the uniformity of airflow distribution in the drum.

[0005] Accordingly, a new technical solution is needed in this field to solve the above problems. Utility Model Content

[0006] This application aims to solve the aforementioned technical problem, namely, to solve the problem of uneven airflow distribution within the garment processing equipment affecting the drying effect of clothes.

[0007] In a first aspect, this application provides a garment processing apparatus, comprising:

[0008] The cylindrical body has an internal cavity for holding clothes, and an air inlet is provided on the cylindrical body;

[0009] The housing has an internal air duct that is connected to the air inlet. An air guide plate is provided inside the air duct, which divides the air duct into multiple sub-channels.

[0010] A fan assembly includes a volute connected to the housing and a fan disposed on the volute, the interior of the volute communicating with the air duct, and one end of the air guide plate extending toward the side where the volute is located.

[0011] In one technical solution of the above-mentioned clothing processing equipment, the air inlet includes a first air inlet located at the upper part of the cylinder and a plurality of second air inlets located at the lower part of the cylinder;

[0012] Each of the sub-channels is provided with a flow guide, which is located between the first air inlet and the second air inlet.

[0013] In one technical solution of the above-mentioned clothing processing equipment, the air guide is disposed near the second air inlet.

[0014] In one technical solution of the above-mentioned clothing processing equipment, the guide member has a tip facing the side where the volute is located, and guide surfaces are formed on both sides of the tip.

[0015] In one technical solution of the aforementioned garment processing equipment, the guide surface is an arc surface; or

[0016] The guide surface is an inclined surface; or

[0017] The guide surface extends along the edge trajectory of the second air inlet.

[0018] In one technical solution of the above-mentioned clothing processing equipment, the guide member is a plate-shaped structure, and the extension direction of the plate-shaped structure is set at an angle to the extension direction of the sub-channel.

[0019] In one technical solution of the above-mentioned clothing processing equipment, the extension direction of the plate-like structure is consistent with the edge trajectory of the second air inlet.

[0020] In one technical solution of the aforementioned garment processing equipment, the edge trajectory of the first air inlet is an arc; and / or

[0021] The two ends of the first air inlet extend toward the side where the second air inlet is located, so that the cross-section of the first air inlet has an arc-shaped structure.

[0022] In one technical solution of the above-mentioned clothing processing equipment, the air duct is arranged in an arc shape near the first air inlet.

[0023] In one technical solution of the aforementioned clothing processing equipment, the cross-sectional area of ​​the volute gradually increases toward its air outlet side.

[0024] As described above, this application, employing the aforementioned technical solution, utilizes guide vanes within the air duct. After the airflow enters the duct through the volute, the vortex at the duct inlet is blocked and dispersed by the guide vanes. Simultaneously, guided by the sub-channels formed between the guide vanes, the airflow moves vertically, creating multiple parallel airflows that finally enter the cylinder from the air inlet. Therefore, the guide vanes reduce the generation of vortices within the air duct, allowing the airflow to move along the duct, thus helping to reduce process pressure loss and noise caused by vortices. Furthermore, the multiple sub-channels formed by the guide vanes guide the airflow path, forcing it to disperse within each sub-channel, thereby improving the uniformity of airflow distribution within the duct and consequently enhancing the uniformity of airflow at various locations within the cylinder, ultimately improving the drying effect of clothing.

[0025] Furthermore, this application provides a first air inlet and a second air inlet on the drum body. Through the arrangement of guide components, the guide components in each sub-channel obstruct the airflow along their path, reducing the airflow velocity. This allows part of the airflow to enter the first air inlet through both sides of the guide components, while the other part enters the second air inlet due to the obstruction of the guide components. This improves the uniformity of the flow distribution at the first and second air inlets, resulting in a more even airflow distribution within the drum body and further enhancing the drying effect on clothes.

[0037] Reference Figure 1 This is a partial structural diagram of a clothing processing device according to an embodiment of this application. The clothing processing device described in this application is exemplified by a clothes dryer. Figure 1 The dryer shown includes a drum 1, a housing 2, and a fan assembly 3. The dryer also includes a main frame. The drum 1 is located within and at the top of the main frame, and has a clothes-holding cavity. The front end of the drum 1 is open, allowing clothes to be placed into the clothes-holding cavity. The housing 2 and fan assembly 3 are both located at the rear end of the drum 1, forming the rear air duct system of the dryer. An air duct is formed inside the housing 2, allowing airflow from below the drum 1 to pass through the fan assembly 3 and then upwards into the drum 1 through the air duct within the housing 2.

[0038] Reference Figure 2 ,for Figure 1 The side view shows that the fan assembly 3 includes a volute 31 and a fan 32 mounted on the volute 31. The interior of the volute 31 is connected to the air duct. The cross-sectional area of ​​the volute 31 gradually increases towards its outlet side. This prevents pressure loss caused by a sudden increase in the cross-section of the outlet of the volute 31, thereby ensuring the airflow, reducing air pressure loss, and lowering noise.

[0039] ReferenceFigure 3 This is a schematic diagram of the rear end of a garment processing device according to an embodiment of this application. The cylinder 1 is provided with an air inlet communicating with the garment receiving cavity inside. Optionally, in one implementation of this application, the air inlet includes a first air inlet 11 located on the upper part of the rear end face of the cylinder 1 and multiple second air inlets 12 located on the lower part of the rear end face of the cylinder 1. The edge trajectory of the first air inlet 11 is arc-shaped, which allows the airflow to pass through the first air inlet 11 more smoothly, avoiding vortices caused by structures such as "sharp corners" or "crossing edges" during the flow of air through the first air inlet 11, thereby improving the aerodynamics of the fluid. Furthermore, the first air inlet 11 is opened laterally, and both ends of the first air inlet 11 extend towards the direction of the second air inlets below it, resulting in an overall arc-shaped or "ingot-shaped" cross-sectional shape for the first air inlet 11. In this case, the total cross-sectional area of ​​the first air inlet 11 is increased, which is beneficial for the airflow into the cylinder 1.

[0040] Optionally, the air duct is arranged in an arc shape at its top, that is, near the first air inlet 11. This arc shape can be understood as the inner wall of the air duct forming a transition rounded corner, so that when the airflow flows vertically to the top of the air duct, it smoothly turns along the arc shape and enters the cylinder 1 through the first air inlet 11. This can reduce the probability of vortex formation at the top of the air duct, thereby reducing pressure loss and flow noise.

[0041] Multiple second air inlets 12 are provided below the first air inlet 11. The accompanying drawings of this application illustrate two second air inlets 12. It should be noted that the specific number and layout of the first air inlets 11 and the second air inlets 12 are determined by the structural characteristics of the dryer. The center of the rear end face of the drum body 1 usually needs to be connected to a drive device to drive the drum body 1 to rotate. Therefore, the first air inlets 11 and the second air inlets 12 need to be arranged around the axis of the drum body 1.

[0042] As can be seen from the above, during the operation of the dryer, the airflow moves laterally in the space below the cylinder 1 to the fan assembly 3, and then turns under the driving force of the fan assembly 3, moving upward in the vertical direction. That is, the air duct also extends vertically. During the movement of the airflow in the air duct, it needs to turn again and enter the cylinder 1 through the first air inlet 11 and the second air inlet 12 for lateral movement. That is, the airflow needs to complete two turns during its movement in the "rear air duct" of the dryer. Therefore, the airflow inevitably generates vortices during this process. In particular, the air duct is the middle channel of the two turns, and the turbulence of the airflow at this position is relatively high, which can easily cause eddies. Therefore, this application aims to reduce the degree of eddies in the air duct, thereby reducing pressure loss and improving the uniformity of airflow distribution.

[0043] Based on this, this application provides an air guide plate 21 inside the housing 2, i.e. inside the air duct. Multiple air guide plates 21 are provided. The air guide plate 21 can be consistent with the extension direction of the air duct, i.e., one end of the air guide plate 21 extends towards the first air inlet 11, and the other end extends towards the side where the volute 31 is located. The air guide plate 21 divides the interior of the air duct into multiple sub-channels.

[0044] As described above, by installing air guide plates 21 inside the air duct, after the airflow enters the air duct through the volute 31, the vortex at the air duct inlet is blocked by the air guide plates 21 and dispersed. Simultaneously, guided by the sub-channels formed between the air guide plates 21, the airflow moves vertically, forming multiple parallel airflows, which finally enter the cylinder 1 through the first air inlet 11 and the second air inlet 12. It is evident that the air guide plates 21 can reduce the generation of vortices within the air duct, allowing the airflow to move along the duct, thus helping to reduce process pressure loss and noise caused by vortices. Furthermore, the multiple sub-channels formed by the air guide plates 21 guide the movement path of the airflow, forcing it to disperse within each sub-channel, thereby improving the uniformity of airflow distribution within the air duct and consequently enhancing the uniformity of airflow at various locations within the cylinder 1, thus improving the drying effect of clothing.

[0045] Reference Figure 3 Furthermore, each sub-channel is also provided with a flow guide 22, which is located between the first air inlet 11 and the second air inlet 12.

[0046] First, it should be understood that during the vertical movement of airflow within the duct, the dynamic pressure of the airflow is greatest at the end of the duct, near the first air inlet 11. Therefore, the airflow at the first air inlet 11 is usually greater than that at the second air inlet 12 below it. This results in a larger gas flow rate in the upper part of the cylinder 1 and a smaller gas flow rate in the lower part, affecting the uniformity of airflow distribution within the cylinder 1 and thus reducing the drying effect on clothes.

[0047] This application utilizes the guide element 22, which obstructs the airflow along its path in each sub-channel, reducing the airflow velocity. This allows a portion of the airflow to enter the first air inlet 11 through both sides of the guide element, while the remaining airflow enters the second air inlet 12 due to the obstruction of the guide element 22. This improves the uniformity of the flow distribution at the first air inlet 11 and the second air inlet 12, resulting in a more even airflow distribution within the cylinder 1 and thus enhancing the drying effect on clothes.

[0048] Optionally, the air guide 22 is positioned near the second air inlet 12, which can further facilitate the airflow blocked by the air guide 22 to enter the second air inlet 12.

[0049] Reference Figure 3In one embodiment of this application, the cross-section of the guide member 22 is V-shaped or U-shaped, that is, the guide member 22 has a pointed tip facing the side where the volute 31 is located, and the two sides of the tip form guide surfaces. When the airflow moves to the position of the guide member 22, it is blocked by the guide member 22, and part of the airflow can flow forward along the two guide surfaces on the guide member 22, thereby reducing the flow resistance. Therefore, based on the consideration of reducing flow resistance, the guide surface can be an arc surface or a slope surface, and the guide surface can also extend along the edge trajectory of the second air inlet 12.

[0050] For example, in Figure 4 In the embodiment shown, one of the flow guides 22 (the flow guide 22 on the right) is configured such that one of the flow guide surfaces extends along the edge trajectory of the second air inlet 12.

[0051] Reference Figure 5 In another embodiment of this application, the guide member 22 may also be a plate-like structure (the plate-like structure is...). Figure 5 The guide 22 on the right side, that is, the guide 22 does not include the above-mentioned "tip", but is only a plate extending in one direction. At this time, the guide 22 has only one guide surface. The extension direction of the plate structure is set at an angle to the extension direction of the sub-channel. Theoretically, as long as the extension direction of the plate structure is not parallel to the sub-channel, it can block the airflow.

[0052] Optionally, the extension direction of the aforementioned plate-like structure is consistent with the edge trajectory of the second air inlet 12. In this way, the flow guide 22 has the greatest obstruction effect on the airflow. The airflow is blocked by the flow guide 22, and most of the airflow can enter the second air inlet 12, while a small part of the airflow flows along the flow guide 22.

[0053] It should be noted that in practical applications, the structures of different guide elements 22 in multiple sub-channels can adopt any combination of the above embodiments, and this application does not impose any restrictions on this.

[0054] The technical solutions of this application have been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of this application is obviously not limited to these specific embodiments. Without departing from the principles of this application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of this application.
