Description

TECHNICAL FIELD

[0001] The utility model relates to clothes processing technical field, especially a clothes processing device. BACKGROUND

[0002] Clothes processing devices such as washing machines, clothes dryers, washing and drying integrated machines are common household appliances. Taking a clothes dryer as an example, the current clothes dryer usually has a drying air duct arranged below a door body, and a lint filter device is arranged in the drying air duct. During the drying process, dry air flow carries away the moisture of clothes in a drum, and also carries lint generated by the clothes. When the wet air flow passes through the lint filter device, the lint is fixed by a filter screen, and the wet air flow continues to circulate through the drying air duct. When there is too much lint and it is not cleaned in time, it is easy to cause blockage, affecting the drying efficiency. In addition, lint flying during the drying process is easy to enter the inside of the machine body. Long-term use of the lint accumulated not only reduces the working efficiency of the clothes dryer, but also easily breeds bacteria and produces odor. SUMMARY

[0003] To solve at least one of the technical problems in the background art, the embodiments of the present application provide a clothes processing device, which can reduce the problem of poor airflow in the machine body air duct caused by lint blockage, ensure the airflow circulation between the machine body air duct and the inner cavity, and ensure the drying efficiency.

[0009] Optionally, the lint removal structure is located outside the door body air duct, and the inlet and outlet of the lint removal structure are connected to two interfaces at different positions of the door body air duct, respectively.

[0010] Optionally, the door duct is provided with an air duct inlet, an air duct outlet and an interface, the interface including a transfer inlet connected to the inlet of the lint removal structure and a transfer outlet connected to the outlet of the lint removal structure;

[0011] Under the action of the door fan, the airflow in the inner cavity enters the lint removal structure through the air duct inlet and the transfer inlet in sequence to remove lint, and then returns to the inner cavity through the transfer outlet and the air duct outlet in sequence.

[0012] Optionally, the door body includes:

[0013] The door body is rotatably connected to the machine body. The door body is provided with a first receiving cavity, an air inlet, and an air outlet. The first receiving cavity is used to at least receive the dandruff removal structure. The air inlet and the air outlet are both located on the side of the door body facing the inner cavity. The air inlet is connected to the air duct inlet. The airflow in the inner cavity enters the air duct inlet through the air inlet and returns to the inner cavity in sequence through the air duct outlet and the air outlet.

[0014] Optionally, the door body further includes:

[0015] A door cover fits over the opening of the first receiving cavity. The door cover is detachably connected to the door body, or the door cover is rotatably connected to the door body, so that the lint removal structure can be placed or removed through the opening of the first receiving cavity.

[0016] Optionally, the first receiving cavity is located on the side of the door body facing the inner cavity; the door body further includes a second receiving cavity disposed on the other side facing away from the inner cavity, the lint removal structure is located in the first receiving cavity, and the door air duct and the door fan are both located in the second receiving cavity.

[0017] Optionally, the air inlet and the air outlet are located at both ends of the door body along the width direction, wherein the width direction is perpendicular to the axis of the cylinder and parallel to the horizontal plane.

[0018] Optionally, the air inlet includes multiple air holes, which are combined to form an arc around the axis of the cylinder.

[0019] Optionally, the door duct includes: an air inlet section, a connecting section, and an air outlet section;

[0025] This utility model has at least the following technical effects:

[0026] Under the action of the door fan, the airflow carrying lint in the inner cavity enters the door duct. After passing through the lint removal structure, the lint is trapped and fixed. The airflow after lint removal then returns to the inner cavity. This lint removal process can be independent of the main air duct. The main air duct can be understood as the original drying air duct in the garment processing device. It can still circulate airflow with the inner cavity without indirectly circulating through the door duct. In other words, the inner cavity can be connected to the main air duct, and at least part of the airflow flowing out of the inner cavity can directly enter the main air duct. Therefore, the drying airflow circulation involving the main air duct and the lint removal airflow circulation involving the door duct can remain relatively independent. Even if the lint removal structure becomes blocked due to excessive lint, the door duct is more affected than the main air duct. The main air duct can still maintain airflow circulation with the inner cavity, ensuring drying efficiency.

[0027] Furthermore, since the lint removal mechanism is part of the door, when the lint removal mechanism becomes clogged and its performance deteriorates, opening the door and moving it away from the main unit makes it easier to replace the lint removal mechanism. Attached Figure Description

Therefore, a feature specified as "first" or "second" can explicitly include at least one of those features. In the description of this invention, "a plurality of" means at least two, such as two, three, etc.

[0044] The clothing handling apparatus of this application includes, but is not limited to, washing machines, dryers, or clothes dryers.

[0045] The following is combined with Figures 1 to 10 The garment processing apparatus of this application embodiment will be described in detail.

[0046] This application provides a garment processing device, such as... Figure 1 As shown, the garment handling device includes: a drum body 30, a main body 20, and a door 10. The drum body 30 has an inner cavity 31 for accommodating garments; the main body 20 has a main body air duct 21 and a main body fan 22; the main body air duct 21 communicates with the inner cavity 31, and the main body fan 22 drives airflow to circulate between the inner cavity 31 and the main body air duct 21; the door 10 is rotatably connected to the main body 20 to open or close the inner cavity 31 for convenient loading and unloading of garments. Figure 2 and Figure 7 As shown, the door body 10 is provided with a door body air duct 110, a door body fan 120 and a lint removal structure 130. The door body air duct 110 is connected to the inner cavity 31. The door body fan 120 can drive the airflow to circulate between the inner cavity 31 and the door body air duct 110. During the circulation process, the airflow returns to the inner cavity 31 after passing through the lint removal structure 130.

[0047] Under the action of the door fan 120, the airflow carrying lint in the inner cavity 31 enters the door air duct 110. After the lint removal structure 130 passes through, the lint is trapped and fixed. The airflow after lint removal returns to the inner cavity 31. This lint removal process can be independent of the machine air duct 21. The machine air duct 21 can be understood as the original drying air duct in the garment processing device. The airflow circulation between it and the inner cavity 31 does not need to pass through the door air duct 110. That is to say, the inner cavity 31 can be connected to the machine air duct 21, and at least part of the airflow flowing out of the inner cavity 31 can directly enter the machine air duct 21. Therefore, the drying airflow circulation involving the machine air duct 21 and the lint removal airflow circulation involving the door air duct 110 can remain relatively independent. Even if the lint removal structure 130 is blocked due to excessive lint, the door air duct 110 is more affected than the machine air duct 21. The machine air duct 21 can still ensure the airflow circulation between it and the inner cavity 31, ensuring drying efficiency.

[0048] It is understandable that the door fan 120 and the main unit fan 22 can operate independently. Door fan 120 may operate before main unit fan 22, and vice versa; or, they may operate alternately. Alternatively, by controlling parameters such as the operating frequency and airflow of their respective fans, door fan 120 and main unit fan 22 may operate simultaneously. The specific method of their combined operation can be selected according to needs, providing greater flexibility.

[0049] In some applications, the door fan 120 operates before the main unit fan 22, or the door fan 120 and the main unit fan 22 operate alternately. Since the airflow filtered by the lint removal structure 130 in the door 10 returns to the inner cavity 31, the amount of lint in the airflow flowing from the inner cavity 31 to the main unit air duct 21 is greatly reduced, eliminating the need for a lint filter in the main unit air duct 21. However, to further prevent the potential impact of small or trace amounts of lint accumulation on internal components such as the motor in the main unit 20, a lint filter can be installed in the main unit air duct 21. It is understandable that because the lint removal structure 130 on the door 10 reduces the lint content in the airflow exiting the inner cavity 31, the replacement frequency of the lint filter in the main unit 20 can be greatly reduced, further lowering the risk of lint affecting internal components such as the motor in the main unit 20.

[0050] Furthermore, since the lint removal structure 130 is part of the door 10, when the lint removal structure 130 experiences a performance decline due to blockage, opening the door 10 and moving the door 10 away from the main body 20 makes it easier to replace the lint removal structure 130.

[0051] In some implementations, the body 20 also includes an outer shell, the cylinder 30 is located inside the outer shell, the body air duct 21 is located in the space between the outer shell and the cylinder 30, and the body fan 22 can be installed in the body air duct 21.

[0052] The inner cavity 31 is the chamber in the drum 30 that holds the clothes. When clothes need to be added or removed from the drum 30, the door 10 can be opened to expose the opening of the inner cavity 31, through which the clothes enter and exit. When the clothes handling device is in operation, the door 10 is closed, sealing the opening, and the clothes undergo drying and other operations in the inner cavity 31. The inlet of the air duct 21 can communicate with the opening of the inner cavity 31.

[0053] For example, the door 10 can be rotatably connected to the body 20 via a structure such as a shaft or hinge.

[0054] Taking a clothes dryer as an example, in some implementations, the body 20 also includes an evaporator. The evaporator is used to dehumidify the humid airflow entering the air duct 21 through the inner cavity 31, turning the humid airflow into dry airflow. The body 20 may also include a condenser, which is used to heat the dehumidified dry airflow to form a dry hot airflow, so that the airflow can circulate back into the drum 30 to dry the clothes again.

[0055] In some alternative embodiments, such as Figure 2 As shown, except for the lint removal structure 130 located in the door air duct 110, the inlet and outlet of the lint removal structure 130 are connected to two interfaces at different locations in the door air duct 110.

[0056] The lint removal structure 130 is located outside the door air duct 110, and the two are connected by an interface. This structure makes the lint removal structure 130 relatively independent from the door air duct 110, making it easier to disassemble or maintain the lint removal structure 130. The assembly of the lint removal structure 130 and the door air duct 110 is also simpler. Moreover, compared to placing the lint removal structure 130 inside the door air duct 110, this method of the present application does not occupy the space inside the air duct 21, allowing the door air duct 110 to have more space and effectively ensuring the lint removal effect.

[0057] Moreover, apart from the lint structure 130 being located in the door duct 110, the two can occupy two different spaces on the door 10, without having to squeeze out a large space. This makes it easier to make reasonable use of the limited space on the door 10, improves space utilization, and makes the structure of the door 10 more compact.

[0058] In some alternative embodiments, such as Figure 3As shown, the door duct 110 is provided with a duct inlet 1111, a duct outlet 1131 and an interface. The interface includes a transfer inlet 1121 connected to the inlet of the lint removal structure 130 and a transfer outlet 1122 connected to the outlet of the lint removal structure 130. Under the action of the door fan 120, the airflow in the inner cavity 31 enters the lint removal structure 130 through the duct inlet 1111 and the transfer inlet 1121 in sequence to remove lint, and then returns to the inner cavity 31 through the transfer outlet 1122 and the duct outlet 1131 in sequence.

[0059] In this embodiment of the application, by providing an interface connected to the lint removal structure 130, the positions of the air duct inlet 1111 and air duct outlet 1131 are not limited by the lint removal structure 130, allowing for more flexible positioning of the air duct inlet 1111 and air duct outlet 1131. (Continue to see...) Figure 3 The interface is located between the air duct inlet 1111 and the air duct outlet 1131. The transition inlet 1121 and the transition outlet 1122 are close together, while the air duct inlet 1111 and the air duct outlet 1131 are far apart. This prevents the airflow discharged from the air duct outlet 1131 from being sucked back into the air duct inlet 1111, thus avoiding airflow short-circuiting. This makes the airflow circulation between the inner cavity 31, the lint removal structure 130 and the door air duct 110 more efficient.

[0060] In some alternative embodiments, such as Figures 2 to 5 As shown, the door body 140 is rotatably connected to the body 20. The door body 140 is provided with a first receiving cavity 141, an air inlet 143 and an air outlet 144. The first receiving cavity 141 is used to at least receive the dandruff removal structure 130. The air inlet 143 and the air outlet 144 are both located on the side of the door body 140 facing the inner cavity 31. The air inlet 143 is connected to the air duct inlet 1111. The airflow in the inner cavity 31 enters the air duct inlet 1111 through the air inlet 143 and returns to the inner cavity 31 in sequence through the air duct outlet 1131 and the air outlet 144.

[0061] For example, the air inlet 143 and the air duct inlet 1111 are located in corresponding positions and fit together tightly. The air duct outlet 1131 can be connected to the fan cover 170 through a rubber joint. The door fan 120 is located inside the fan cover 170, and the air outlet of the door fan 120 is connected to the air outlet 144. That is to say, the air duct outlet 1131 is connected to the air outlet 144 through the fan.

[0062] For example, both the door duct 110 and the fan cover 170 can be fixed to the door body 140 by screws, and the screw fixing position can have a shock-absorbing pad (such as a shock-absorbing rubber pad) to reduce or even avoid the vibration of the door fan 120.

[0063] Generally, the door body 140 can serve as a support or mounting carrier to support the lint removal structure 130, the door air duct 110, or even the door fan 120.

[0064] In the embodiment illustrated in this application, the first receiving cavity 141 is used to receive the dandruff removal structure 130, while the door duct 110 and the door fan 120 are located in the second receiving cavity 142 (mentioned below). See also Figure 5 The first receiving cavity 141 is a recessed chamber of the door body 140 outward (in the direction away from the inner cavity 31), which is roughly located in the upper part of the door body 140. This makes the structure more compact.

[0065] In some other implementations, at least one of the door duct 110 and the door fan 120 may be located in the first receiving cavity 141, without the need for other receiving cavities.

[0066] In some alternative embodiments, such as Figure 5 As shown, the door body 10 also includes a door cover 150, which covers the opening of the first receiving cavity 141. The door cover 150 is detachably connected to the door body 140 so as to open or close the first receiving cavity 141 and to take out or put in the lint removal structure 130 through the opening of the first receiving cavity 141.

[0067] The door cover 150 protects the structure within the first receiving cavity 141 and also improves the overall appearance and simplicity of the door 10, enhancing the user experience. For example, after the door cover 150 closes to the first receiving cavity 141, there is a smooth transition between the door cover 150 and the door body 140, and the inner appearance of the door 10 can maintain a similar appearance to existing door bodies. See some implementations for details. Figure 2 Compared to the door body 10 in the prior art, the inner wall of the door body 10 is more vertical.

[0068] The door cover 150 can be connected by fasteners such as snap-fit, magnetic attraction, screws or bolts, or can be detached by other means.

[0069] In other embodiments, the door cover 150 is rotatably connected to the door body 140 to open or close the first receiving cavity 141 and to remove or place the lint removal structure 130 from the first receiving cavity 141.

[0070] The door cover 150 can be rotatably connected to the door body 140 by means of a shaft or hinge.

[0071] In some alternative embodiments, such as Figure 5 As shown, the first receiving cavity 141 is located on the side of the door body 140 facing the inner cavity 31; as Figure 2 and Figure 7 As shown, the door body 140 also includes a second receiving cavity 142 disposed on the other side opposite to the inner cavity 31, a lint removal structure 130 located in the first receiving cavity 141, and a door air duct 110 and a door fan 120 both located in the second receiving cavity 142.

[0072] Combination Figure 2 , Figure 5 and Figure 7 As shown, the first receiving cavity 141 and the second receiving cavity 142 are located on opposite sides of the door body 140, with the first receiving cavity 141 approximately above the second receiving cavity 142. The vertical projections of the first receiving cavity 141 and the second receiving cavity 142 at least partially overlap. This arrangement makes full use of the limited space of the door body 140, and compared to the door body 10 in the prior art, it can minimize the increase in the volume of the door body 10 (e.g., the thickness of the door body 10), or even not increase the thickness of the door body 10 at all.

[0073] In some alternative embodiments, such as Figure 4 and Figure 6 As shown, the air inlet 143 and air outlet 144 are located at both ends of the door body 140 along the width direction, where the width direction is perpendicular to the axis of the cylinder 30 and parallel to the horizontal plane. This arrangement of the air inlet 143 and air outlet 144 as far apart as possible on the door body 140 increases the distance between them, preventing the airflow discharged from the air outlet 144 from being drawn back into the air inlet 143, thus avoiding airflow short-circuiting. This makes the airflow circulation between the inner cavity 31, the lint removal structure 130, and the door duct 110 more efficient, ensuring airflow circulation within the cylinder 30.

[0074] In some alternative embodiments, such as Figure 4 As shown, the air inlet 143 includes multiple air holes, which are combined to form an arc around the axis of the cylinder 30.

[0075] See also Figure 4 The air vents are small-diameter holes, and "multiple" here can refer to dozens, hundreds, or even more, with no specific limit on the number. In the implementation shown in the figure of this application, the multiple air vents forming the air inlet 143 are roughly divided into three rows, and the multiple air vents in each row are distributed roughly along an arc-shaped trajectory around the axis of the cylinder 30.

[0076] See Figure 4 , Figure 5 and Figure 6 The air inlet 143 can also be formed by multiple air holes. The air inlet 143 and air outlet 144 formed by multiple air holes can also filter the airflow to a certain extent and prevent clothing or large-volume impurities from entering the door 10 through the air outlet 144 or air inlet 143.

[0077] The arc-shaped air inlet 143 can avoid the lint removal structure 130 while cooperating with the aforementioned air outlet 144 to ensure airflow circulation within the cylinder 30.

[0078] The arc-shaped air inlet 143 has a larger area, which can increase the air volume and improve the lint removal effect.

[0079] Typically, the machine body 20 also houses a motor assembly that drives the drum 30 to rotate. When the drum 30 rotates, the clothes are lifted by the lifting ribs inside the drum 30, reach a certain height, and then fall freely. This repeated "throwing" motion follows an arc-shaped trajectory roughly along the axis of the drum 30. Matching the shape of the air inlet 143 to the movement trajectory of the clothes inside the drum 30 helps more lint and dander enter the air inlet 143, further improving the lint removal effect.

[0080] In some alternative embodiments, such as Figure 2 and Figure 3 As shown, the door duct 110 includes an air inlet section 111, a connecting section 112, and an air outlet section 113. The connecting section 112 connects the air inlet section 111 and the air outlet section 113 at its two ends. The air inlet section 111 has an air duct inlet 1111 that matches the air inlet 143. The connecting section 112 has a transition inlet 1121 and a transition outlet 1122. The air outlet section 113 has an air duct outlet 1131. This structure effectively ensures the length of the door duct 110, extends the residence time of the airflow within the door 10, and thus improves the dandruff removal effect.

[0081] Combination Figure 3 and Figure 4 The air duct inlet 1111 is not only aligned with the air inlet 143 in terms of position, but its shape and size are also roughly the same as those of the air inlet 143. This allows the airflow entering from the air inlet 143 to flow deeper into the door air duct 110.

[0082] The multi-segmented door duct 110 can make fuller use of the space of the second receiving cavity 142 and improve the structural compactness.

[0083] The door duct 110 can be a physically inseparable integral structure, for example, the door duct 110 is a one-piece molded component.

[0084] In some alternative embodiments, such as Figure 2 and Figure 3 As shown, the air intake section 111 is arc-shaped, and the air intake section 111 and the connecting section 112 together form a D-shaped structure. This layout helps to further improve the utilization rate of the space of the door 10, and the structure is more compact.

[0085] See Figure 2 and Figure 3The connecting section 112 is set roughly vertically, while the air outlet section 113 is set roughly horizontally. In the width direction, the air inlet section 111 and the air outlet section 113 are located on opposite sides of the connecting section 112. The top of the air inlet section 111 is connected to the top of the connecting section 112, and the air outlet section 113 is connected to the bottom of the connecting section 112. The transition inlet 1121 and the transition outlet 1122 are both located above the connecting section 112, while the bottom of the air inlet section 111 and the air outlet section 113 are roughly at the same height. This layout is compact and makes more rational use of space.

[0086] In some alternative embodiments, in the axial projection along the cylinder 30, the lint removal structure 130 is located above the air outlet section 113, and the door fan 120 is disposed in the air outlet section 113. See also Figure 2 In this way, the lint removal structure 130 and the door fan 120 are staggered in the axial projection of the cylinder 30, so that they will not overlap in this direction and increase the thickness of the door 10. Therefore, this layout helps to reduce the increase in the thickness of the door 10.

[0087] In some alternative embodiments, the lint removal structure 130 is detachably connected to the door body 140 or the door cover 150. This facilitates the replacement, maintenance, or inspection of the lint removal structure 130.

[0088] Detachable methods include, but are not limited to, snap-fit, magnetic connection, or fastener connection such as screws.

[0089] In the embodiment illustrated in this application, the lint removal structure 130 is detachably connected to the door body 140. When it is necessary to replace, repair, or inspect the lint removal structure 130, the door cover 150 can be removed first, and then the lint removal structure 130 can be removed.

[0090] In some implementations, the lint removal structure 130 is detachably connected to the door cover 150. When the door cover 150 is removed, the lint removal structure 130 can be separated from the door body 140 simultaneously with the door cover 150. This one-step operation allows for the removal or installation of the lint removal structure 130, making it more convenient to use.

[0091] For example, one end of the door cover 150 is snapped into the door body 140, and the other end of the door cover 150 is fastened to the door body 140. See also Figure 5 In the implementation shown, one end of the door cover 150 is provided with a cover claw 152, and the corresponding position of the door body 140 is provided with a cover slot 145; the other end of the door cover 150 has a cover latch structure, which includes a cover latch 153 and a cover adjusting member for controlling the extension and retraction of the cover latch 153. The cover adjusting member can be... Figure 6The cover button 151 shown is not limited to this. The door cover 150 can be pre-installed by engaging the cover latch 152 into the cover slot 145, and then the door cover 150 is secured by engaging the cover groove 148 on the door body 140 via the cover latch 153. The cover adjustment component can easily control the extension and retraction of the cover latch 153, enabling the cover latch 153 to connect or disconnect from the door body 140. This method eliminates the need for tools to disassemble or install the door cover 150, making it convenient to operate.

[0092] For example, such as Figure 8 As shown, the detachable connection between the lint removal structure 130 and the door body 140 can be the same as the detachable connection between the door cover 150 and the door body 140. For example... Figure 9 As shown, one end of the dandruff removal structure 130 (corresponding to) Figure 8 A cup-claw 131 is provided at point A in the middle, and a cup-claw groove 146 is provided at the corresponding position on the door body 140. The cup-claw 131 can be inserted into the cup-claw groove 146 to achieve pre-installation between the lint removal structure 130 and the door body 140; after pre-installation, the other end of the lint removal structure 130 (corresponding to Figure 8 The door body 140 is connected to the door at point B via a cup-locking structure 147. The cup-locking structure 147 includes a cup lock 1471 and a cup adjustment component that controls the extension and retraction of the cup lock 1471. The difference is that the cup lock structure 147 is located on the door body 140, and the lint removal structure 130 has a cup groove 132 corresponding to the position of the cup lock 1471. The cup adjustment component can be… Figure 10 The cup button shown is 1474.

[0093] See also Figure 10 The cup lock 1471 and the cup button 1474 are roughly vertically distributed. The cup lock 1471 and the cup button 1474 abut against each other via an inclined surface 1475. When the cup button 1474 is pressed, it pushes the cup lock 1471 back through the abutting inclined surface 1475, facilitating the cup lock 1471 to enter the cup groove 132. It is understood that when the lint removal structure 130 needs to be installed, it is not necessary to press the cup button 1474. By applying pressure to the lint removal structure 130, the cup lock 1471 can also be engaged into the cup groove 132 using the guide surface and other structures at the end of the cup lock 1471.

[0094] The cup lock structure 147 may further include a first elastic element 1472 that provides elastic force for the cup lock 1471 to extend and a second elastic element 1473 that provides elastic force for the adjustment element to return to its original position. After the cup lock 1471 enters the cup groove 132, the pressing force can be removed, and the first elastic element 1472 releases energy to make the cup lock 1471 pop out. The cup lock 1471 can then lock the cup groove 132, preventing the other end of the lint removal structure 130 from separating from the door body 140.

[0095] When it is necessary to disassemble the lint removal structure 130, press the button, and the cup button 1474 pushes the cup lock 1471 back through the abutting inclined surface 1475. The connection between the cup lock 1471 and the cup groove 132 is released, and the lint removal structure 130 can be easily removed.

[0096] In some alternative embodiments, the lint removal structure 130 includes a dust cup and a filter assembly located within the dust cup.

[0097] The lint removal structure 130 can be detachably connected to the door body 140 via a dust cup.

[0098] The filter components can be HEPA filters, sponges, or dust bags, etc.

[0099] The filter components can be replaced, and new filter components can be replaced after long-term use. The dust cup can be reused, which not only ensures the lint removal effect, but also makes it more economical.
