Description

Technical Field

[0001] The utility model relates to the technical field of clothing processing devices, and in particular to an air duct component and a clothing processing device. Background Art

[0002] The distribution of water volume in the water collection tank below the evaporator, the direction of water flow and the speed of water flow are affected by wind force and gravity. Since the airflow at the water collection tank flows from the first air inlet to the first air outlet along a first direction, the water flow is driven by the airflow to gather toward the side wall of the water collection tank close to the first air outlet. When the amount of water gathered here is too much, the water will overflow over the side wall of the water collection tank close to the first air outlet and overflow out of the water collection tank. In the related technology, there is an air duct assembly with a water retaining rib structure extending along a second direction in the water collection tank, so as to use the water retaining rib to block part of the water from flowing toward the side wall of the water collection tank close to the air outlet. The water is collected on the side wall on the side, but the water retaining ribs separate the water collecting tank into two independent parts, and the two drainage grooves are not connected. When the amount of water near the air outlet is large, the drainage groove on the other side of the water retaining rib cannot be used to divert the water, and the drainage performance is poor. In addition, there are some areas where the water flow rate is fast, while the water flow rate is slow in some local areas. Water is easy to accumulate in the place where the water flow rate is slow. When the amount of water concentrated here is too much, the water is easy to overflow the side wall of the water collecting tank and overflow out of the water collecting tank. When the water flow rate is too slow, the water cannot be discharged from the drain outlet of the water collecting tank in time. There is room for improvement. Utility Model Content

DETAILED DESCRIPTION

[0039] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0040] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature.

[0041] Reference below Figure 1-Figure 11 An air duct assembly according to an embodiment of the utility model is described.

[0042] The air duct assembly according to the embodiment of the utility model may include: a shell and an evaporator 21 .

[0043] The shell defines an air duct cavity, and the evaporator 21 is arranged in the air duct cavity. The evaporator 21 is used to cool and dehumidify the airflow in the air duct cavity. The bottom wall of the air duct cavity below the evaporator 21 has at least one water collecting groove 11 extending along the second direction. The second direction is Figure 1 , Figure 3 and Figure 5 In the CD direction shown in , the water collecting tank 11 can receive the condensed water generated from the evaporator 21 and the wall of the air duct cavity, avoid the accumulation of water in the air duct cavity and affect the life of the structure in the air duct cavity, and facilitate the discharge of water.

[0044] The distribution of water in the water collecting tank 11, the direction of water flow and the flow velocity are affected by wind and gravity. Driven by the airflow, the water flows toward the side wall of the water collecting tank 11 close to the air outlet. When the amount of water gathered here is too much, the water will overflow over the side wall of the water collecting tank 11 close to the air outlet and overflow out of the water collecting tank 11.

[0045] In the related art, there is an air duct assembly designed with a water retaining rib structure extending along a second direction in the water collecting trough, so as to utilize the water retaining rib to block part of the water from gathering to the side wall of the water collecting trough close to the air outlet. However, since the water retaining rib divides the water collecting trough into two independent parts, the drainage grooves of the two parts are not connected. When there is a large amount of water close to the air outlet, the drainage groove on the other side of the water retaining rib cannot be used to divert the water, resulting in poor drainage performance.

[0046] Moreover, part of the airflow will generate turbulence under the obstruction of the structure inside the water collection tank 11 and the side wall of the water collection tank 11. In some areas, the airflow direction is the same as the water discharge direction, and the water flow rate is fast, while in some areas, the airflow direction is opposite to the water discharge direction, and the water flow rate is slow. Water is easy to accumulate in the slow water flow rate. When the amount of water concentrated here is too much, the water is easy to overflow the side wall of the water collection tank 11 and overflow out of the water collection tank 11. When the water flow rate is too slow, there is also a situation where the water flow cannot be discharged from the drain port of the water collection tank 11 in time, resulting in more water gathering in the water collection tank 11. At this time, the water will overflow the side wall of the water collection tank 11 and overflow the water collection tank 11.

[0047] To this end, the embodiment of the utility model designs an air duct assembly with a water guide member on the bottom wall of the water collecting tank 11, thereby, the water flow in the water collecting tank 11 can be guided by the water guide member and can be more evenly distributed in the water collecting tank 11, so as to avoid the water flow being concentrated on one side under the action of wind, which causes water to overflow from the water collecting tank 11 to the outside of the water collecting tank 11, and the water guide member can also guide the wind direction so that the wind direction is controllable, so that the water flow velocity in the corresponding area can be slowed down or accelerated under the action of wind, and the drainage can be accelerated at the place where the water flow converges and the water volume is large, thereby improving the drainage efficiency, and the water flow velocity can be slowed down at the place where the water volume is small, so as to make the water volume uniform everywhere and reduce the risk of water overflowing from the water collecting tank 11.

[0048] Among them, the bottom wall of the water collecting tank 11 is provided with a water guiding member, which divides the water collecting tank 11 into a first water tank 111 and a second water tank 112 arranged in a first direction and connected. Part of the water is blocked by the water guiding member in the process of flowing toward the air outlet, and will not gather on the side wall of the water collecting tank 11 close to the air outlet, thereby avoiding the risk of water concentrating on the side wall of the water collecting tank 11 close to the air outlet and overflowing from the water collecting tank 11 to the outside of the water collecting tank 11. In the first direction, the water volume distribution in various places in the water collecting tank 11 is more even.

[0049] Furthermore, since the water guide member can connect the first water tank 111 and the second water tank 112, when the amount of water in the first water tank 111 is large, the second water tank 112 can be used to divert the water, and when the amount of water in the second water tank 112 is large, the first water tank 111 can be used to divert the water, and the drainage effect of the water collection tank is better.

[0050] Furthermore, the water guide member includes a plurality of water guide ribs 12 arranged along the second direction, and the plurality of water guide ribs 12 together separate the water collecting tank 11 into a first water tank 111 and a second water tank 112 arranged in the first direction and connected to each other.

[0051] At least one water-guiding rib 12 is at least partially inclined relative to the second direction, so that when the airflow passes through the water-guiding rib 12, it will flow along the extension direction of the water-guiding rib 12 under the guidance of the water-guiding rib 12. The direction of the airflow can be controlled by the direction of the water-guiding rib 12, and the flow speed of the water can be controlled to slow down or accelerate under the action of the airflow. In places where the water flow is concentrated and the water volume is large, the airflow direction can be controlled to be the same as the drainage direction to increase the speed of water flowing to the drain outlet, improve the drainage efficiency, and reduce the water volume there. In places where the water flow is dispersed and the water volume is small, the airflow direction can be controlled to be opposite to the drainage direction to reduce the speed of the water converging to the place with a larger water volume, even out the water volume at each place, and reduce the risk of water overflowing from the sump 11.

[0052] According to the air duct assembly of the embodiment of the utility model, the air duct assembly arranges a water guide in the water collecting tank 11 below the evaporator 21, so that the water volume in each part of the water collecting tank 11 is reasonably distributed, thereby reducing the risk of water overflowing from the water collecting tank 11.

[0053] The air duct cavity has a first air inlet 31 and a first air outlet 32, and the first direction is as follows Figure 1 , Figure 3 , Figure 5 and Figure 7In the AB direction shown in the figure, the air flow in the air duct cavity flows from the first air inlet 31 to the first air outlet 32, that is, the air flow in the air duct cavity mainly flows along the first direction, and flows from the first air inlet 31 to the first air outlet 32, and the air flow at the water collecting tank 11 flows along the first direction from the first air inlet 31 to the first air outlet 32, and the water flow is driven by the air flow to gather on the side wall of the water collecting tank 11 close to the first air outlet 32.

[0054] like Figure 1-Figure 4 As shown, a drain port is provided on the bottom wall of the air duct cavity for discharging the water collected in the sump 11 to the outside of the air duct assembly. The drainage speed at the drain port determines the amount of water collected in the sump 11. When the water flow speed at the drain port is fast and the drainage volume is large, the amount of water collected in the sump 11 is balanced, which can greatly reduce the risk of water overflowing from the sump 11.

[0055] Among them, the drain outlet is arranged at one end of the water collecting tank 11 in the second direction to facilitate the opening of the drain outlet. In the direction close to the drain outlet, the bottom wall of the water collecting tank 11 is inclined from top to bottom to utilize gravity so that water can flow to the drain outlet and can flow to the drain outlet more quickly, avoiding water accumulation in the water collecting tank 11 and causing water overflow. The increase in water flow rate can also improve the drainage efficiency at the drain outlet, ensuring that the drainage efficiency is greater than the water generation efficiency, and reducing the risk of water accumulation in the water collecting tank 11 and overflow.

[0056] Reference Figure 1-Figure 10 At least one water guide rib 12 is at least partially arranged along the first direction from the first air inlet 31 to the first air outlet 32, and is inclined toward the direction close to the drain outlet. As a result, when the airflow passes through the water guide rib 12, it is guided by the water guide rib 12 and flows obliquely toward the direction close to the drain outlet. Driven by the airflow, the water in the water collection tank 11 can be accelerated to flow toward the drain outlet. As a result, the water flow velocity in the water collection tank 11 and the drainage speed at the drain outlet can be accelerated, avoiding water accumulation in the water collection tank 11, ensuring that the drainage efficiency is greater than the water generation efficiency, and reducing the risk of water accumulation in the water collection tank 11 and overflow.

[0057] In some embodiments, when the drainage speed of the drain outlet is slower than the speed at which the water gathers at the drain outlet, the water flow will accumulate around the drain outlet and overflow. Therefore, in this case, the speed at which the water gathers at the drain outlet should be appropriately reduced. Fig.11 At least one water guide rib 12 is at least partially arranged along the first direction from the first air inlet 31 to the first air outlet 32, and is inclined in the direction away from the drain outlet. At this time, when the airflow passes through the water guide rib 12, it is guided by the water guide rib 12 and flows in the direction away from the drain outlet. Driven by the airflow, the water in the water collecting tank 11 flows toward the drain outlet at a slower speed, thereby reducing the amount of water accumulated at the drain outlet and reducing the risk of water overflowing around the drain outlet.

[0058] Reference Figure 1-Figure 4 The drain outlet includes a first drain outlet 131 and a second drain outlet 132 , and the water collecting tank 11 is drained through the two drain outlets to ensure drainage efficiency and prevent water from accumulating in the water collecting tank 11 and causing the water in the water collecting tank 11 to overflow outside the water collecting tank 11 .

[0059] Among them, the first drain outlet 131 is arranged opposite to one end of the first water tank 111 in the second direction, and the second drain outlet 132 is arranged opposite to one end of the second water tank 112 in the second direction, so that when the water flow in the first water tank 111 flows along the second direction and reaches one end in the second direction, it can be discharged through the first drain outlet 131 in time, ensuring the water flow rate at the first drain outlet 131, so that when the water flow in the second water tank 112 flows along the second direction and reaches one end in the second direction, it can be discharged through the second drain outlet 132 in time, ensuring the water flow rate at the second drain outlet 132, avoiding the water flow from accumulating at one end in the second direction of the water collecting tank 11, resulting in excessive local water volume and water overflow.

[0060] Reference Figure 5 and Figure 6 Since the evaporator 21 is placed flat in the air duct cavity, and the bottom wall of the water collecting tank 11 is inclined from top to bottom in the direction close to the drain outlet, that is, in the direction close to the drain outlet, the distance between the evaporator 21 and the bottom wall of the water collecting tank 11 gradually increases, and the water guiding ribs 12 are arranged between the evaporator 21 and the bottom wall of the water collecting tank 11. Therefore, among the multiple water guiding ribs 12 in the water collecting tank 11, the heights of the multiple water guiding ribs 12 increase gradually in the direction close to the drain outlet to guide the water dripping from the evaporator 21 between the evaporator 21 and the bottom wall of the water collecting tank 11.

[0061] Furthermore, since the amount of water increases as the water gathers in the direction approaching the drain outlet, and the amount of water collected in the sump 11 is positively correlated with the depth of the sump 11, the depth of the sump 11 increases in the direction approaching the drain outlet, and among the multiple water guide ribs 12 in the sump 11, the heights of the multiple water guide ribs 12 increase in the direction approaching the drain outlet.

[0062] like Figure 5-Figure 8 As shown, a protrusion 14 is provided in the air duct cavity, and the evaporator 21 is supported above the protrusion 14 to ensure the stability of the evaporator 21. The top of the water guide rib 12 is not higher than the top of the protrusion 14 to avoid deformation of the water guide rib 12 due to the weight of the evaporator 21 being mainly borne by the water guide rib 12 during the installation process, thereby ensuring the stability of the evaporator 21.

[0063] In some embodiments, the evaporator 21 is also supported above a plurality of water guiding ribs 12 , so that the top of the water guiding ribs 12 can directly contact the bottom of the evaporator 21 to guide the water dripping from the evaporator 21 , thereby improving the water guiding performance of the water guiding ribs 12 .

[0064] According to some embodiments of the utility model, the air duct assembly also includes: a condenser, which is arranged in the air duct cavity and is used to increase the temperature of the airflow. In the gas flow direction in the air duct cavity, the condenser is located downstream of the evaporator 21 to ensure the dehumidification effect of the evaporator 21 on the airflow.

[0065] Reference Figure 1-Figure 4 A water retaining rib 15 is provided in the air duct cavity, and the water retaining rib 15 extends along the second direction and is located between the evaporator 21 and the condenser to prevent the water flow in the water collecting tank 11 from flowing over the water retaining rib 15 to the bottom of the condenser, thereby affecting the service life of the condenser.

[0066] like Figure 1 and Figure 3 As shown, the air duct cavity includes a first installation space 10 connected to the first air inlet 31 and a second installation space 20 connected to the first air outlet 32. After the airflow enters the air duct cavity through the first air inlet 31, it first passes through the first installation space 10. After the airflow is fully in contact with and processed by the structure in the first installation space 10, it flows along the first direction and enters the second installation space 20. After being processed by the structure provided in the second installation space 20, it flows out of the air duct cavity through the first air outlet 32.

[0067] Among them, the first installation space 10 and the second installation space 20 are arranged in the first direction so that when the airflow flows from the first installation space 10 to the second installation space 20, the airflow is evenly distributed in various places in the second installation space 20, ensuring that the airflow in the second installation space 20 is evenly distributed.

[0068] The evaporator 21 is disposed in the second installation space 20. Figure 2 The air duct assembly also includes a filtering device, which is arranged in the first installation space 10. Therefore, after the airflow enters the air duct cavity through the first air inlet 31, it first passes through the first installation space 10, is filtered by the filtering device in the first installation space 10, and then flows along the first direction to enter the second installation space 20. After being processed by the evaporator 21 and the condenser arranged in the second installation space 20, it flows out of the air duct cavity through the first air outlet 32.

[0069] A clothes processing device according to an embodiment of the second aspect of the utility model comprises the air duct assembly of the above embodiment.

[0070] Reference Figure 1The clothing processing device also includes: a clothing processing drum assembly, the clothing processing drum assembly has a clothing processing chamber, a second air inlet and a second air outlet connected to the clothing processing chamber, wherein the first air outlet 32 ​​is connected to the second air inlet, and the first air inlet 31 is connected to the second air outlet.

[0071] In the clothing processing device, the airflow in the air duct cavity is driven by the fan and enters the clothing processing cavity through the second air inlet, participates in the drying and hair removal of the clothing, and is discharged through the second air outlet after being fully processed with the clothing. The airflow discharged from the clothing processing cavity returns to the air duct cavity through the first air inlet 31. After the airflow enters the air duct cavity through the first air inlet 31, it first passes through the first installation space 10, and after being filtered by the filter device in the first installation space 10, it flows along the first direction and enters the second installation space 20. After being processed by the evaporator 21 and the condenser arranged in the second installation space 20, it flows out of the air duct cavity through the first air outlet 32.

[0072] A specific embodiment of the clothes treating device is described below with reference to the accompanying drawings.

[0073] like Figure 1 As shown, the clothes processing device includes: a clothes processing drum assembly and an air duct assembly.

[0074] The clothing processing drum assembly has a clothing processing chamber, a second air inlet and a second air outlet connected to the clothing processing chamber, the air duct assembly includes a shell, an evaporator 21, a condenser and a filter assembly, the shell includes an upper shell and a lower shell 1, the shell defines an air duct chamber, the air duct chamber has a first air inlet 31 and a first air outlet 32 ​​arranged in a first direction, and also includes a first installation space 10 connected to the first air inlet 31, and a second installation space 20 connected to the first air outlet 32, the first installation space 10 and the second installation space 20 are arranged in the first direction, the filter device is arranged in the first installation space 10, the evaporator 21 and the condenser are arranged in the second installation space 20, and in the gas flow direction in the air duct chamber, the condenser is located downstream of the evaporator 21.

[0075] In the clothing processing device, the airflow in the air duct cavity is driven by the fan and enters the clothing processing cavity through the second air inlet, participates in the drying and hair removal of the clothing, and is discharged through the second air outlet after being fully processed with the clothing. The airflow discharged from the clothing processing cavity returns to the air duct cavity through the first air inlet 31. After the airflow enters the air duct cavity through the first air inlet 31, it first passes through the first installation space 10, and after being filtered by the filter device in the first installation space 10, it flows along the first direction and enters the second installation space 20. After being processed by the evaporator 21 and the condenser arranged in the second installation space 20, it flows out of the air duct cavity through the first air outlet 32.

[0076] In the area where the evaporator 21 is located, the airflow mainly flows along the first direction from the side close to the first air inlet 31 to the side close to the first air outlet 32. The bottom wall of the air duct cavity below the evaporator 21 has a water collecting groove 11 extending along the second direction. The water collecting groove 11 is used to receive condensed water generated from the evaporator 21 and the wall surface of the air duct cavity. A water guide is provided on the bottom wall of the water collecting groove 11. The water guide includes a plurality of water guiding ribs 12 arranged in the second direction. The plurality of water guiding ribs 12 together divide the water collecting groove 11 into a first water groove 111 and a second water groove 112 arranged in the first direction and connected.

[0077] As a result, part of the water is blocked by the water guide member when flowing toward the first air outlet 32, and will not gather on the side wall of the water collecting tank 11 near the first air outlet 32, thereby avoiding the risk of water concentrating on the side wall of the water collecting tank 11 near the first air outlet 32 ​​and overflowing from the water collecting tank 11 to the outside of the water collecting tank 11. In the first direction, the water volume distribution in various places in the water collecting tank 11 is more even.

[0078] A protrusion 14 and a water retaining rib 15 are respectively provided on both sides of the water collecting tank 11 in the first direction. The water retaining rib 15 extends in the second direction and is located between the evaporator 21 and the condenser to prevent the water in the water collecting tank 11 from flowing over the water retaining rib 15 to the bottom of the condenser, thereby affecting the service life of the condenser. At least a portion of the protrusion 14 extends in the second direction, the top of the water guiding rib 12 is flush with the top of the protrusion 14, and the evaporator 21 is supported and arranged above the protrusion 14 and the water guiding rib 12 at the same time.

[0079] The bottom wall of the air duct cavity is provided with a drain outlet, which includes two drain outlets, namely a first drain outlet 131 and a second drain outlet 132. The first drain outlet 131 and the second drain outlet 132 are arranged at the same end of the water collecting trough 11 in the second direction. The first drain outlet 131 is arranged opposite to the first water trough 111, and the second drain outlet 132 is arranged opposite to the second water trough 112. In the direction close to the drain outlet, the bottom wall of the water collecting trough 11 is inclined from top to bottom.

[0080] The evaporator 21 is placed flat in the air duct cavity. In the direction close to the drain outlet, the distance between the evaporator 21 and the bottom wall of the water collecting tank 11 gradually increases. The water guiding ribs 12 and the protrusions 14 are arranged between the evaporator 21 and the bottom wall of the water collecting tank 11. Therefore, among the multiple water guiding ribs 12 in the water collecting tank 11, the heights of the multiple water guiding ribs 12 increase in the direction close to the drain outlet, and the heights of the protrusions 14 also increase in the direction close to the drain outlet.

[0081] Furthermore, since the amount of water increases as the water gathers in the direction approaching the drain outlet, and the amount of water collected in the sump 11 is positively correlated with the depth of the sump 11, the depth of the sump 11 should increase in the direction approaching the drain outlet. When the height of the protrusion 14 is constant, the height of the water retaining rib 15 determines the depth of the sump 11. Therefore, the height of the water retaining rib 15 increases in the direction approaching the drain outlet.

[0082] In some embodiments, reference Figure 1-Figure 10 The water guide rib 12 is arranged along the first direction from the first air inlet 31 to the first air outlet 32, and is inclined toward the direction close to the drain outlet. When the airflow passes through the water guide rib 12, it is guided by the water guide rib 12 and flows obliquely toward the direction close to the drain outlet. Driven by the airflow, the water in the water collection tank 11 can be accelerated to flow toward the drain outlet. As a result, the water flow velocity in the water collection tank 11 and the drainage speed at the drain outlet can be accelerated, avoiding water accumulation in the water collection tank 11, ensuring that the drainage efficiency is greater than the water generation efficiency, and reducing the risk of water accumulating in the water collection tank 11 and overflowing.

[0083] Among them, refer to Figure 1-Figure 8 The water guide rib 12 can be inclined at a certain angle along the first direction from the first air inlet 31 to the first air outlet 32 ​​toward the direction close to the drain outlet.

[0084] Or, refer to Fig. 9 The water guide rib 12 is arranged along the first direction from the first air inlet 31 to the first air outlet 32, and is inclined toward the direction close to the drain outlet, and the angle between the water guide rib 12 and the first direction decreases gradually, so as to better guide the airflow and reduce the impact of the airflow on the water guide rib 12.

[0085] Or, refer to Fig.10 The water guide rib 12 is arranged along the first direction from the first air inlet 31 to the first air outlet 32 ​​, and is inclined toward the direction close to the drain outlet, and the angle between the water guide rib 12 and the first direction increases gradually, so as to better guide the airflow and reduce the impact of the airflow on the water guide rib 12 .

[0086] In other embodiments, when the drainage speed of the drain outlet is slower than the speed at which the water gathers at the drain outlet, the water flow will accumulate around the drain outlet and overflow. Therefore, in this case, the speed at which the water gathers at the drain outlet needs to be appropriately reduced, such as Fig.11As shown, part of the water guide rib 12 is arranged along the first direction from the first air inlet 31 to the first air outlet 32, and is inclined in the direction away from the drain outlet. The other part of the water guide rib 12 is arranged along the first direction from the first air inlet 31 to the first air outlet 32, and is inclined in the direction close to the drain outlet. At this time, when the airflow passes through the water guide rib 12 which is inclined in the direction away from the drain outlet, it is guided by the water guide rib 12 and flows in the direction away from the drain outlet. Driven by the airflow, the water in the water collecting tank 11 flows toward the drain outlet at a slower speed, thereby reducing the amount of water accumulated at the drain outlet and reducing the risk of water overflowing around the drain outlet.
