Description

Technical Field

[0001] This utility model relates to the field of clothing cleaning technology, and in particular to a clothing processing device. Background Technology

[0002] Over time, dirt gradually accumulates between the inner and outer drums of a washing machine. With the door closed, the interior is enclosed. If clothes are not removed promptly after washing, mold can quickly grow, causing unpleasant odors and affecting the quality of the wash. If the washing machine lacks a dedicated air conditioning or moisture extraction system, poor air circulation exacerbates moisture retention, leading not only to odors but also potential corrosion or damage to electrical components and metal parts. To mitigate this, existing technologies incorporate a fresh air intake system. To ensure convenient airflow, a vent is often located on the front of the machine, with the air duct directly connected. While this design ensures good ventilation, it is aesthetically unappealing and allows dust and other debris to easily enter through the vent, making cleaning difficult. Utility Model Content

[0052] In the description of this embodiment, it should be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", "front", "rear", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0053] As a specific embodiment of this utility model, this embodiment provides a clothing processing device 100, which may include a box (not shown in the figure), a cylinder 110, and a valve assembly 120. A front panel 130 is provided on the front side of the box, and a vent 131 is provided on the front panel 130. The cylinder 110 is located inside the box. The valve assembly 120 is located between the box and the cylinder 110, connected to the front panel 130, and the valve assembly 120 is controllably moved to open or close the vent 131, so that gas inside the cylinder 110 is discharged outside the box through the vent 131, or gas outside the box flows into the cylinder 110 through the vent 131.

[0054] Specifically, the garment processing device 100 of this embodiment may include a housing, a drum 110, and a valve assembly 120. A front panel 130 is provided on the front side of the housing, and a vent 131 may also be provided on the front panel 130. The vent 131 allows for the exchange of gases between the inside of the housing and the outside of the drum 110. The garment processing device 100 of this embodiment may also include a valve assembly 120, which is disposed between the housing and the drum 110. The valve assembly 120 can open and close the vent 131, which on the one hand improves the aesthetics of the front panel 130, and on the other hand prevents foreign objects from entering the housing and the drum 110 through the vent 131, thereby contaminating the housing and the drum 110 and making cleaning difficult.

[0055] Specifically, in this embodiment, the front panel 130 can be a front door or a control panel. Of course, the vent 131 is generally located at the position corresponding to the control buttons. For example... Figures 1-3 The front panel 130 shown in the image is a control panel, and the air vent 131 is located on the control panel, with the air vent 131 and the control buttons on the same horizontal plane.

[0056] Figure 1 and Figure 2 These are all schematic diagrams of the valve assembly 120 opening the ventilation port 131. At this time, the valve assembly 120 opens the ventilation port 131, and ventilation can be carried out outside the box and inside the cylinder 110 through the ventilation port 131.

[0057] Figure 3 The diagram shows the valve assembly 120 closing the vent 131. At this time, the vent 131 is blocked by the valve assembly 120, which not only improves the aesthetics of the front panel 130, but also prevents foreign objects from entering the interior through the vent 131.

[0058] As a specific embodiment of this utility model, the valve assembly 120 of this embodiment may include a drive mechanism 121 and a sealing member 122. The sealing member 122 is connected to the drive mechanism 121 so that when it moves to the vent 131 under the drive of the drive mechanism 121, it closes the vent 131, and when it moves away from the vent 131 under the drive of the drive mechanism 121, it opens the vent 131.

[0059] Specifically, in this embodiment, the drive mechanism 121 drives the closing member 122 to move, and the closing member 122 opens and closes the vent 131. When the vent 131 needs ventilation, the drive mechanism 121 drives the closing member 122 to open the vent 131, so as not to affect the ventilation of the vent 131. When the vent 131 does not need ventilation, the drive mechanism 121 drives the closing member 122 to close the vent 131, so that the vent 131 is blocked, improving the aesthetics, and preventing foreign objects from entering the box or cylinder 110 through the vent 131.

[0060] As a specific embodiment of this utility model, the drive mechanism 121 of this embodiment may include a motor assembly 1211 and an output assembly 1212 connected to the motor assembly 1211. The output assembly 1212 moves telescopically along the direction perpendicular to the front panel 130 under the drive of the motor assembly 1211. The closure 122 is connected to the output assembly 1212 to follow the output assembly 1212 in telescopic movement along the direction perpendicular to the front panel 130, thereby opening or closing the vent 131.

[0061] Specifically, in this embodiment, the closure 122 is connected to the motor assembly 1211 via the output assembly 1212. The motor assembly 1211 drives the output assembly 1212 to move, and the output assembly 1212 then drives the closure 122 to move. Since the output assembly 1212 extends and retracts along the direction perpendicular to the front panel 130, the closure 122 also moves along the direction perpendicular to the front panel 130.

[0062] More specifically, the motor assembly 1211 may include a motor 1213 and a screw 1214. The screw 1214 is connected to the motor 1213 and rotates under the drive of the motor 1213. The output assembly 1212 may include a base 1215 and at least one connecting rod 1216. The base 1215 is provided with a first through hole 1217, and the inner wall of the first through hole 1217 is provided with an internal thread so that when the screw 1214 is passed through the first through hole 1217, the internal thread engages with the screw 1214, and the screw 1214 drives the base to move along the axial direction of the screw 1214. At least one connecting rod 1216 connects the base 1215 and the closure 122, so that when the base 1215 moves, the connecting rod 1216 drives the closure 122 to move.

[0063] Specifically, in this embodiment, the connecting rod 1216 can be arranged parallel to the screw 1214. The base 1215 and the sealing plate 1221 are connected by the connecting rod 1216, and the base 1215 is rotatably connected to the screw 1214. Thus, when the screw 1214 rotates, the base 1215 moves along the axial direction of the screw 1214, and the base 1215 then drives the connecting rod 1216 and the sealing plate 1221 to move.

[0064] Preferably, in this embodiment, there are multiple connecting rods 1216, which are arranged in parallel on the side of the screw 1214. Specifically, in this embodiment, there are two connecting rods 1216, which are arranged above the screw 1214.

[0065] More specifically, in this embodiment, the connecting rod 1216 and the closure 122 are integrally formed, and the end of the connecting rod 1216 is connected to the base 1215 by fasteners.

[0066] As a specific embodiment of the present invention, the closure member 122 may include a closure plate 1221. The structure of the closure plate 1221 matches the structure of the vent 131, so that when the closure member 122 moves to close the vent 131, the closure plate 1221 is located inside the vent 131, and the surface of the closure plate 1221 is on the same plane as the outer side of the front panel 130.

[0067] Specifically, the structure of the sealing plate 1221 matches the vent 131, and when the sealing member 122 closes the vent 131, the sealing plate 1221 is sealed inside the vent 131, and its outer side is on the same plane as the outer side of the front panel 130. This ensures the aesthetics of the front side of the front panel 130 and prevents foreign objects from entering the inside of the front panel 130 through the vent 131.

[0068] Specifically, the shape of the vent 131 in this embodiment can be circular, square or other arbitrary shapes. The shape of the sealing plate 1221 is the same as that of the vent 131, and its size is slightly smaller than that of the vent 131, so that the sealing plate 1221 can close the entire vent 131 when it is inside the vent 131.

[0069] Specifically, the closure 122 may also include a limiting member 1222 located inside the closure plate 1221, the limiting member 1222 connecting the connecting rod 1216 to the closure plate 1221.

[0070] Specifically, the connecting rod 1216, the limiting member 1222, and the closing plate 1221 are integrally formed.

[0071] The limiting member 1222 is located inside the sealing plate 1221. When the sealing plate 1221 opens the vent 131 under the drive of the drive mechanism 121, the limiting member 1222 is located at the vent 131 and is limited by the limiting member 1222 to prevent the sealing member 122 from shaking in the vertical movement direction, thereby preventing the sealing plate 1221 from failing to close the vent 131 smoothly.

[0072] The shape of the outer contour of the cross section of the limiting member 1222 after being cut in the plane perpendicular to the direction of movement of the sealing plate 1221 is the same as the shape of the vent 131. For example, if the vent 131 in this embodiment is square, then the outer contour of the cross section of the limiting member 1222 is also square. Thus, when the sealing plate 1221 leaves the vent 131, the limiting member 1222 is stuck at the vent 131, preventing the limiting plate from shaking and thus preventing the limiting plate from blocking the vent 131.

[0073] Specifically, in this embodiment, the outer periphery of the limiting member 1222 is provided with at least one ventilation groove 1223 so that when the sealing member 122 leaves the ventilation opening 131, the limiting member 1222 is located at the ventilation opening 131, and the gas in front and behind the front panel 130 flows through the ventilation groove 1223 at the ventilation opening 131.

[0074] Specifically, the number, shape and size of the ventilation slots 1223 can be designed according to the actual situation. It is only necessary to ensure that when the ventilation opening 131 is opened on the closed plate 1221 and the limiting member 1222 is located at the ventilation opening 131, the gas can flow back and forth on the front panel 130 through the ventilation slots 1223.

[0075] In one embodiment, the number of ventilation slots 1223 is multiple, and each ventilation slot 1223 extends along the direction perpendicular to the closure member 122. The multiple ventilation slots 1223 are arranged side-by-side along the outer periphery of the limiting member 1222. Specifically, the cross-section of the ventilation slot 1223 can be square, triangular, or other shapes.

[0076] As a specific embodiment of this utility model, the clothing processing device 100 of this embodiment may further include a housing 140. The housing 140 covers the side of the front panel 130 near the cylinder 110 at the vent 131. The housing 140 is provided with a second through hole 141 so that the gas inside the front panel 130 can circulate with the housing 140 through the second through hole 141, and the gas inside the housing 140 can circulate with the gas outside the front panel 130 through the vent 131.

[0077] Specifically, in this embodiment, by setting up the housing 140, it can support the valve assembly 120 on the one hand, and serve as a connection and buffer part for ventilation vent 131 on the other hand. Thus, gas can flow between the inside of the housing 140 and the outside of the front panel 130 through the ventilation vent 131, and gas can flow between the inside of the housing 140 and other parts through the second through hole 141. This allows gas to flow between the inside and outside of the front panel 130, and also allows gas inside the cylinder 110 to flow with gas outside the box.

[0078] More specifically, in this embodiment, a mounting portion 142 is provided inside the housing 140 for mounting the motor 1213. The mounting portion 142 extends from the side wall of the housing 140 toward the center and has a mounting hole. A connecting portion is provided at the motor 1213 to connect with the mounting hole, and the motor 1213 is then mounted at the mounting portion 142 by fasteners.

[0079] Specifically, the mounting portion 142 may include at least two, thus ensuring the stability of the motor 1213 installation. In this embodiment, the mounting portion 142 includes two parts, which are respectively disposed on the left and right side walls of the housing 140.

[0080] As a specific embodiment of this utility model, the garment handling device 100 of this embodiment further includes a guide rail 150. The guide rail 150 extends from the inner wall of the housing 140 on the side away from the front panel 130 to the closure member 122. A third through hole 1218 is provided at the base 1215, and the guide rail 150 passes through the third through hole 1218, thereby causing the base 1215 to move along the guide rail 150 under the drive of the drive mechanism 121.

[0081] Specifically, in this embodiment, the guide rail 150 extends in a direction parallel to the movement direction of the closing plate 1221. A third through hole 1218 is provided at the base 1215, and the cross-section of the guide rail 150 has the same cross-sectional shape as the third through hole 1218. This allows the base 1215 to move along the guide rail 150 under the drive of the drive mechanism 121.

[0082] Specifically, the guide rail 150 is parallel to the screw 1214. By setting the guide rail 150, the stability of the movement of the base 1215 can be increased.

[0083] In one embodiment, a first groove 1224 is provided at the limiting member 1222 to avoid the screw 1214. This prevents the limiting member 1222 from interfering with the screw 1214 during movement.

[0084] Specifically, a second groove 1225 is provided at the limiting member 1222 to avoid the guide rail 150. This avoids interference between the limiting member 1222 and the screw 1214 during movement, and also allows the guide rail 150 to engage with the limiting member 1222 through the second groove 1225, so that the limiting member 1222 also moves along the guide rail 150, thereby improving the stability of the movement.

[0085] As a specific embodiment of this utility model, the clothing handling device 100 of this embodiment may further include a fresh air assembly 160. The fresh air assembly 160 may include an air inlet pipe, a main body, and an air outlet pipe connected in sequence. The end of the air inlet pipe away from the main body is connected to a second through hole 141 to introduce fresh air from outside the front panel 130 into the main body through the vent 131 and the second through hole 141. The end of the air outlet pipe away from the main body is connected to the cylinder 110 to introduce fresh air passing through the main body into the cylinder 110 through the air outlet pipe.

[0086] Specifically, when the fresh air assembly 160 is turned on, the valve assembly 120 is driven by the drive mechanism 121 to open the vent 131. At this time, the sealing plate 1221 moves forward of the vent 131 and leaves the vent 131, thereby opening the vent 131. The fresh air assembly 160 introduces the fresh air from the outside of the front panel 130 into the housing 140 through the vent 131, and then from the housing 140 through the second through hole 141 and the air inlet pipe to the main body. The main body then blows the fresh air into the cylinder 110 through the air outlet pipe, thereby realizing that the fresh air inside the cylinder 110 is the real fresh air from the outside. When the fresh air assembly 160 is closed, fresh air is not needed. The drive mechanism 121 drives the valve assembly 120 to close the vent 131. The sealing plate 1221 moves into the vent 131, and the outer side of the sealing plate 1221 is on the same plane as the front side of the front panel 130. This ensures aesthetics and prevents foreign objects from entering the interior of the housing through the vent 131, thus reducing cleaning difficulty and shortening the service life.

[0087] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention.
