Description

Technical Field

[0001] This invention belongs to the field of clothing processing devices, and more specifically, relates to a clothing processing device and its door lock. Background Art

[0002] In existing technologies, door locks are often installed exposed or partially exposed within the front flange of garment processing devices, and are typically secured by clips on the positioning wall. Over time, this can cause the lock to detach from the clips, resulting in unstable connections and loosening, which can affect the accurate positioning of the door hook and lock hole, causing the door to jam. The front flange of garment processing devices is usually made of ordinary plastic, which has a low melting point and is flammable and easily deformed. To ensure a tight seal, garment processing devices often use electrical connections at the door lock, requiring cables to pass through the front flange. Therefore, if the cables at the door lock age, or if electrical components short-circuit, or if the door lock loosens due to prolonged use and fails to make proper contact with the door hook, causing electrical sparks, a fire could easily ignite the garment processing device, potentially causing serious fire damage to the user's home.

[0003] In view of this, the present invention is proposed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a door lock for a garment processing device. By setting the door lock as an independent module, the door lock can be stably installed on the front flange of the garment processing device, thereby improving the positioning accuracy.

[0005] The present invention also provides a clothing handling device for installing the door lock.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is: a door lock for a clothing handling device, comprising:

[0007] The protective shell is a thin-walled box-shaped body with an internal cavity and a through hole on one side; the protective shell is provided with a connecting part for fixing it to the clothing processing device.

[0008] The door lock cylinder is detachably installed in a cavity inside the protective housing, and the position and size of the lock hole of the door lock cylinder match the through hole on the protective housing.

[0009] The door hook is detachably installed at the lock hole.

[0010] By modularly and integrally setting the door lock cylinder within the protective housing, the door lock cylinder can be positioned by fixing the protective housing. This prevents the door lock cylinder from shifting after long-term use, which could lead to inaccurate positioning of the door hook and lock hole, causing the door to jam.

[0011] Furthermore, the protective housing includes:

[0012] The main body has an open side, with a positioning edge extending outward from the open side into the cavity.

[0013] The cover is located at the opening of the main body;

[0014] The connecting part includes a first mounting hole and a second mounting hole. The first mounting hole is disposed on the positioning edge, and the second mounting hole is disposed on the cover body corresponding to the first mounting hole.

[0015] Preferably, the number of the first assembly holes is at least three, and they are evenly distributed on the positioning edge.

[0016] As described above, the body and the cover work together to form a closed cavity that can be detachably installed to accommodate the door lock cylinder, providing all-round protection for the door lock cylinder; the first and second mounting holes are provided on the body and the cover to achieve accurate positioning of the protective shell.

[0017] Furthermore, a positioning protrusion is provided on the door lock cylinder, and a positioning hole is provided on the protective shell with a through hole at a position corresponding to the matching positioning protrusion. The positioning protrusion passes through the positioning hole and is locked in place.

[0018] Preferably, there are at least two positioning protrusions, and the size and number of positioning holes are consistent with those of the positioning protrusions.

[0019] As described above, by setting a positioning protrusion on the door lock cylinder and a positioning hole on the protective shell, the positioning protrusion is embedded in the positioning hole during assembly, so that the two match and the door lock cylinder is positioned inside the protective shell, unable to move or rotate freely.

[0020] Furthermore, the wall of the keyhole protrudes from the surface of the lock cylinder and extends into a neck, which passes through the through hole.

[0021] The neck of the lock hole passes through the through hole, which can further position the lock cylinder and make the positioning and matching of the lock hole and the door hook more accurate; at the same time, a protective structure is formed at the through hole to prevent the door hook from contacting the protective shell.

[0022] Furthermore, the neck folds outward and extends along the outer surface of the protective shell as an outer edge.

[0023] The cross-section of the outer edge is trapezoidal, and the lower base of the trapezoid fits against the outer surface of the protective shell.

[0024] As can be seen from the above, an outer edge is set at the keyhole to block the through hole, preventing the door lock cylinder from falling off the protective shell at will, and also making the overall effect of the protective shell more aesthetically pleasing.

[0025] Furthermore, at least a portion of the outer wall at the connection between the keyhole and the neck is provided with a raised edge, the surface of the raised edge facing the outer edge extending from the outer wall of the keyhole away from the outer edge.

[0026] As can be seen from the above, by setting a protruding edge, the door lock cylinder can be snapped into the through hole, and with the bevel of the outer edge, the door lock cylinder can be inserted obliquely into the through hole for assembly and positioning, so that it cannot fall off at will.

[0027] Furthermore, the protective outer shell is made of fire-retardant material.

[0028] Preferably, the body and / or cover of the protective shell are sheet metal parts.

[0029] As can be seen from the above, using fire-resistant materials can prevent losses caused by electrical fires to the greatest extent possible, and also buys valuable rescue time for taking effective measures to control the fire in time when it breaks out, which is very necessary.

[0030] Matching the size of the protective shell's enclosed cavity to the door lock cylinder can more effectively save space and better control the amount of oxygen inside the cavity, causing any sparks or flames to extinguish automatically due to lack of oxygen, thus reducing the probability of a fire.

[0031] Furthermore, a garment handling device includes a front flange of the body and a door, the door being pivotally connected to the front flange of the body; characterized in that it further includes a door lock as described above.

[0032] The door lock is located on the opposite side of the door pivot of the garment handling device, the door hook is located on the door, and the protective shell and the door lock cylinder are integrally mounted on the front flange of the machine body.

[0033] By installing the aforementioned door lock on the garment handling device, the positioning problem of the door lock can be better solved through technological innovation, preventing the lock hole and door hook from becoming inaccurately positioned due to long-term use, thus avoiding jamming when opening and closing the door.

[0034] Furthermore, the front flange of the machine body is provided with cross-connected reinforcing ribs at the position matching the positioning edge of the protective shell, and a threaded post integrally injection molded with the reinforcing ribs is provided at the intersection of the reinforcing ribs. The connecting part of the protective shell is fixed to the threaded post by threaded connection.

[0035] As can be seen from the above, in conjunction with the structure of the protective shell, the reinforcing ribs with cross connections are set on the front flange of the machine body, and threaded posts are set at the intersections. This allows the protective shell to be easily fixed to the threaded posts by threads, and it also has a good effect in withstanding the impact force when the door hook opens and closes.

[0036] Furthermore, the door lock cylinder is connected to a communication cable, and a notch is provided on the lower part of the protective housing away from the door body, through which the communication cable passes.

[0037] As can be seen from the above, setting a gap near the bottom of the protective casing for communication cables to pass through can prevent upward-burning flames from bursting out of the protective casing in the event of a fire, thereby reducing the damage caused by the fire.

[0038] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0039] By integrating the protective shell and the lock cylinder into a modular design, and using the connecting part of the protective shell to fix it to the front flange of the body, the lock cylinder can be stably fastened to the body. This solves the problems of poor contact caused by the lock cylinder being snapped onto the front flange of the body by long-term vibration, resulting in the lock cylinder coming off the snap and the door jamming.

[0040] With its modular design integrating the protective shell and door lock cylinder, the door hook is inserted into the lock cylinder's keyhole through the through-hole in the protective shell. Even if an electrical spark is generated due to poor contact, it is contained within the protective shell. Furthermore, the protective shell is made of fire-resistant material, so even if the internal electrical connection circuit of the door lock cylinder accidentally catches fire, it will be contained within the protective shell for a period of time. This effectively prevents damage to the washing machine body, reduces losses caused by fire, and buys valuable rescue time for electrical fire rescue.

[0061] like Figures 1 to 6 As shown, the door lock of the garment handling device of the present invention includes:

[0062] The protective shell 1 is a thin-walled box-shaped body with an internal cavity and a through hole 13 on one side; the protective shell 1 is provided with a connecting part 14 for fixing to the clothing processing device.

[0063] The door lock cylinder 2 is detachably installed in the cavity inside the protective housing 1. The position and size of the lock hole 21 of the door lock cylinder 2 match the through hole 13 on the protective housing 1.

[0064] The door hook 3 is detachably installed at the lock hole 21.

[0065] The protective outer shell 1 includes:

[0066] The main body 11 has one side open, and a positioning edge 111 extends outward from the opening into the cavity.

[0067] The cover 12 is located at the opening of the main body 11.

[0068] The connecting part 14 includes a first mounting hole 141 and a second mounting hole 142. The first mounting hole 141 is disposed on the positioning edge 111, and the second mounting hole 142 is disposed on the cover body 12 corresponding to the first mounting hole 141.

[0069] The door lock cylinder 2 is provided with a positioning protrusion 22. The protective shell 1 has a positioning hole 15 on the surface with the through hole 13, corresponding to the position of the positioning protrusion 22. The positioning protrusion 22 passes through the positioning hole 15 and is locked in place. The wall of the lock hole 21 protrudes from the surface of the door lock cylinder 2 and extends into a neck 23. The neck 23 passes through the through hole 13. The neck 23 is folded outward and extends along the outer surface of the protective shell 1 into an outer edge 24. At least part of the outer wall at the connection between the lock hole 21 and the neck 23 is provided with a protruding edge 25. The surface of the protruding edge 25 facing the outer edge 24 extends from the outer wall of the lock hole 21 away from the outer edge 24.

[0070] The protective outer shell 1 is made of fire-resistant material.

[0071] A garment handling device of the present invention includes a front flange 5 of the body and a door 4, wherein the door 4 is pivotally connected to the front flange 5 of the body; characterized in that it further includes a door lock as described above.

[0072] The door lock is located on the opposite side of the pivot of the door body 4 of the clothing handling device, the door hook 3 is located on the door body 4, and the protective shell 1 and the door lock core 2 are integrally set on the front flange 5 of the machine body.

[0073] like Figures 1-3 As shown, the door lock of the garment handling device described in this embodiment includes:

[0074] The protective outer shell 1 is a thin-walled box-shaped body with an internal cavity and a square through hole 13 on one side. This reserved square through hole 13 is used to position the square lock hole 21 of the door lock cylinder 2, and can also allow the door hook 3 to pass smoothly into the square lock hole 21 to lock the door 4 of the clothing handling device. The protective outer shell 1 is provided with a connecting part 14 for directly fixing the protective outer shell 1 to the clothing handling device.

[0075] The door lock cylinder 2 is detachably installed in the cavity inside the protective shell 1. The position and size of the square lock hole 21 of the door lock cylinder 2 match the square through hole 13 on the protective shell 1. The door lock cylinder 2 is installed inside the protective shell 1 and is integrated with the protective shell 1 to form a module, which is convenient for direct installation onto the clothing processing device later.

[0076] The door hook 3 is detachably installed at the lock hole 21.

[0077] The protective outer shell 1 includes:

[0078] The main body 11 is a square box-shaped body with one side open. The door lock cylinder 2 is assembled into the square cavity of the main body 11 through the open side. A positioning edge 111 extends outward from the open side of the square cavity. The connecting part 14 includes four first mounting holes 141, which are evenly distributed in pairs on the positioning edge 111. Alternatively, more holes can be arranged symmetrically on the outer edge.

[0079] The cover 12 is disposed at the opening of the body 11 and covers the body 11. The cover 12 has a thin-walled structure. The connecting part 14 also includes a second mounting hole 142, which matches the first mounting hole 141 on the body 11.

[0080] The body 11 and the cover 12 cooperate to seal the door lock cylinder 2 assembled in the cavity of the body 11. In order to save the space occupied by the protective shell 1, the cavity space of the protective shell 1 should be matched with the door lock cylinder 2 as small as possible, so as to save limited space while facilitating assembly.

[0081] The advantages of this design are twofold: Firstly, it protects the door lock cylinder 2, preventing dust from entering and causing jamming or malfunction. Secondly, since the door lock cylinder 2 is electrically connected, in the event of a fire, the confined internal space and limited oxygen supply will easily extinguish small flames, preventing them from spreading into a large fire.

[0082] The door lock cylinder 2 has a positioning protrusion 22 on one side with a lock hole 21. The protective shell 1 has a positioning hole 15 on one side with a square through hole 13, corresponding to the position of the positioning protrusion 22. The height of the positioning protrusion 22 is similar to the wall thickness of the hole in the body 11, so that the positioning protrusion 22 passes through the positioning hole 15 and is locked in place.

[0083] There are two positioning protrusions 22, which are respectively set on both sides of the lock hole 21. The positioning protrusions 22 are cylindrical in shape and similar in size to the positioning hole 15. In this way, when the positioning protrusions 22 are engaged in the positioning hole 15 of the body 11, the door lock cylinder 2 cannot move horizontally. The two positioning protrusions 22 restrain each other, so that the door lock cylinder 2 cannot rotate, thus achieving stable positioning of the door lock cylinder 2 on the protective shell 1.

[0084] like Figures 4-6 As shown, the wall surface at the keyhole 21 protrudes from the surface of the door lock cylinder 2 and extends into a neck 23, which passes through the through hole 13. The neck 23 folds outward and extends along the outer surface of the protective shell 1 as an outer edge 24. The cross-section of the outer edge 24 is trapezoidal, and the lower base of the trapezoid fits against the outer surface of the protective shell 1, blocking the through hole 13 of the protective shell 1.

[0085] The wall of the lock hole 21 extends outward and folds to form a neck 23 and an outer edge 24, which passes through the through hole 13 of the protective shell 1. On the one hand, the lock cylinder 2 is stuck by the trapezoidal outer edge 24, and cannot automatically detach from the body 11 after installation, thus realizing the integrated structure of the lock cylinder 2 and the protective shell 1. On the other hand, the trapezoidal outer edge 24 blocks the through hole 13, making the lock look more aesthetically pleasing. The slope of the trapezoidal structure also makes it easier for the door hook 3 to enter the lock hole 21, realizing the accurate positioning of the door hook 3 and the lock hole 21 and preventing jamming.

[0086] To achieve nail-free installation of the lock cylinder 2 and the protective shell 1, facilitating assembly without tools, at least a portion of the outer wall at the connection between the lock hole 21 and the neck 23 is provided with a protruding edge 25. The surface of the protruding edge 25 facing the outer edge 24 extends from the outer wall of the lock hole 21 away from the outer edge 24, forming a process installation slope. This process installation slope, in conjunction with the opposite trapezoidal slope, allows one side of the outer edge 24 of the lock cylinder 2 to pass obliquely through the through hole 13 of the body 11, and then the other side of the lock cylinder 2 to be lifted flat, so that the entire outer edge 24 of the lock cylinder 2 passes through the through hole 13. At this time, with the help of the positioning protrusion, the lock cylinder 2 is moved so that the outer edge 24 of the lock cylinder 2 is evenly distributed on the surface of the upper part of the through hole 13, and the positioning protrusion enters the positioning hole 15, achieving nail-free positioning of the lock cylinder 2 within the body 11.

[0087] To prevent water leakage from the door 4 during the washing process, which could be caused by accidental opening by the user or mischievous children, a door lock is needed to maintain a tight seal and prevent water from seeping out through gaps in the door 4. Therefore, the door lock cylinder 2 is typically controlled by an electrical connection. Communication between the door lock cylinder 2 and the control panel requires electrical components or communication cables.

[0088] If the clothing handling device is used for a long time, it can cause problems such as aging of the communication cables and electric sparks at the cable contacts. If the door hook 3 is not positioned accurately when it enters the lock hole 21 and is locked, it can also cause electric sparks. All of these factors can easily cause a fire that burns the clothing handling device, or even cause a house fire. Once a fire occurs, the economic losses are enormous. Therefore, the protective shell 1 is made of fire-resistant material. Preferably, the body 11 and / or cover 12 of the protective shell 1 are sheet metal parts, which are not only easy to roll and form, but also prevent flames inside the door lock cylinder 2 from quickly escaping and burning the front flange 5 of the machine body.

[0089] The enclosed cavity of the protective shell 1 matches the size of the door lock cylinder 2. This not only saves assembly space for the door lock, but also further restricts the space in which the door lock cylinder 2 comes into contact with the surrounding oxygen. In many small fires, the oxygen is easily and quickly consumed, causing the fire in the door lock cylinder 2 to extinguish automatically and preventing the fire from spreading.

[0090] This integrated enclosed assembly method of the door lock cylinder 2 through the protective shell 1 greatly reduces the probability of fire in the clothing handling device itself. In the event of a fire, the fire-resistant and flame-retardant properties of the protective shell 1 provide more valuable time for fire fighting and reduce the economic losses caused by the fire.

[0091] A washing machine according to the present invention is equipped with a door lock as described above. Typically, the door lock is located on the opposite side of the pivot of the door body 4 of the clothes handling device, with the door hook 3 located on the door body 4, and the protective housing 1 and the door lock cylinder 2 integrally mounted on the front flange 5 of the machine body.

[0092] A cross-connected reinforcing rib 51 is provided on the front flange 5 of the machine body at the position matching the positioning edge 111 of the protective shell 1. A threaded post 52, integrally injection molded with the reinforcing rib 51, is provided at the intersection of the reinforcing ribs 51. This ensures uniform stress distribution on the front flange 5 of the machine body, sufficient strength to meet design requirements, and provides a more accurate installation base for the door lock with the protective shell 1. The protective shell 1 is fixed to the threaded post 52 via a threaded connection, preventing it from dislodging even after long-term use, thus preventing inaccurate positioning of the door hook 3 and lock hole 21, and causing jamming when the door 4 is opened and closed. This solves the problem of the original method of using positioning ribs and clips on the front flange 5 of the machine body to engage the door lock cylinder 2, which caused the door lock cylinder 2 to disengage and shift after repeated opening and closing of the door 4.

[0093] Because the door lock cylinders 2 have different shapes and types, multiple door lock cylinders 2 of similar size can be embedded and protected inside them using the same protective shell 1. The same connecting part 14 can also be set on multiple protective shells 1 of similar shape to achieve uniformity of assembly size. This reduces the mold problem of designing different positioning structure walls for the front flange 5 of the body for different shaped door lock cylinders 2. The existing assembly structure of the front flange 5 with reinforcing ribs 51 and threaded post 52 can be used to assemble more door locks with different structures or functions, indirectly saving production and manufacturing costs.

[0094] At the front flange 5 of the machine body, there is also a front panel 6, which together with the front flange 5 of the machine body clamps the door lock with the protective shell 1, so that the door lock is hidden inside, making the appearance of the garment handling device beautiful and elegant.

[0095] The door lock cylinder 2 is connected to a communication cable, and a notch 16 is provided on the lower part of the protective shell 1 away from the door body 4, through which the communication cable passes.

[0096] In this way, when a fire occurs, the flames usually burn upwards, avoiding the possibility of flames emerging from the bottom and sides and igniting other flammable materials, thus greatly reducing the risk of fire. Placing the communication cable on the side away from door 4 allows for a simpler cable arrangement utilizing the gaps in the side wall of the clothing handling device, leading directly to the control panel.

[0097] Another embodiment described in this example is a door lock for a clothing handling device, comprising:

[0098] The protective outer shell 1 is a thin-walled box-shaped body with an internal cavity and a circular through hole 13 on one side. This reserved circular through hole 13 is used to position the circular lock hole 21 of the door lock cylinder 2, and can also allow the door hook 3 to pass smoothly into the circular lock hole 21 to lock the door 4 of the clothing handling device. The protective outer shell 1 is provided with a connecting part 14 for directly fixing the protective outer shell 1 to the clothing handling device.

[0099] The door lock cylinder 2 is detachably installed in the cavity inside the protective shell 1. The position and size of the square lock hole 21 of the door lock cylinder 2 match the square through hole 13 on the protective shell 1. The door lock cylinder 2 is installed inside the protective shell 1 and is integrated with the protective shell 1 to form a module, which is convenient for direct installation onto the clothing processing device later.

[0100] The door hook 3 is detachably installed at the lock hole 21.

[0101] The protective outer shell 1 includes:

[0102] The main body 11 is a circular box-shaped body with one side open. The door lock cylinder 2 is assembled into the circular cavity of the main body 11 through the open side. A positioning edge 111 extends outward from the open side of the circular cavity. The connecting part 14 includes three first mounting holes 141, which are evenly distributed around the positioning edge 111. Alternatively, there may be more holes evenly distributed around the positioning edge.

[0103] The cover 12 is disposed at the opening of the body 11 and covers the body 11. The cover 12 has a thin-walled structure. The connecting part 14 also includes a second mounting hole 142, which matches the first mounting hole 141 on the body 11.

[0104] The main body 11 and the cover 12 cooperate to enclose the door lock cylinder 2 assembled on the cover 12 into the cavity of the main body 11, thus performing modular integrated assembly.

[0105] The door lock cylinder 2 has a positioning protrusion 22 on one side with a lock hole 21. The cover 12 of the protective shell 1 has a positioning hole 15 on one side with a circular through hole 13, which corresponds to the position of the positioning protrusion 22. The height of the positioning protrusion 22 is similar to the wall thickness of the hole in the body 11, so that the positioning protrusion 22 passes through the positioning hole 15 and is locked in place.

[0106] There are two positioning protrusions 22, which are respectively set on both sides of the lock hole 21. The positioning protrusions 22 are cylindrical in shape and similar in size to the positioning hole 15. In this way, when the positioning protrusions 22 are engaged in the positioning hole 15 of the body 11, the door lock cylinder 2 cannot move horizontally. The two positioning protrusions 22 restrain each other, so that the door lock cylinder 2 cannot rotate either, thus achieving stable positioning of the door lock cylinder 2 on the cover 12 of the protective shell 1.

[0107] The wall surface at the keyhole 21 protrudes from the surface of the lock cylinder 2 and extends into a neck 23, which passes through the through hole 13. The neck 23 folds outward and extends along the outer surface of the protective housing 1 as an outer edge 24. The outer edge 24 consists of two segments connected by the neck 23, symmetrically arranged at the keyhole 21. The cross-section of the outer edge 24 is trapezoidal, with the lower base of the trapezoid fitting against the outer surface of the protective housing 1, blocking the through hole 13 of the protective housing 1.

[0108] To achieve nail-free installation of the lock cylinder 2 and the protective shell 1, facilitating assembly without tools, at least a portion of the outer wall at the connection between the lock hole 21 and the neck 23 is provided with a protruding edge 25. The surface of the protruding edge 25 facing the outer edge 24 extends from the outer wall of the lock hole 21 away from the outer edge 24, forming a process installation slope. This process installation slope, in conjunction with the opposite trapezoidal slope, allows one side of the outer edge 24 of the lock cylinder 2 to pass obliquely through the through hole 13 of the cover 12, and then the other side of the lock cylinder 2 to be lifted flat, so that the entire outer edge 24 of the lock cylinder 2 passes through the through hole 13. At this time, with the help of the positioning protrusion, the lock cylinder 2 is moved so that the outer edge 24 of the lock cylinder 2 is evenly distributed on the surface of the upper part of the through hole 13, and the positioning protrusion enters the positioning hole 15, achieving nail-free positioning of the lock cylinder 2 on the cover 12.

[0109] To ensure a tight seal and prevent washing water from leaking out through gaps in the door body 4, the door lock cylinder 2 is typically controlled by an electrical connection. Communication between the door lock cylinder 2 and the control panel requires electrical components or communication cables.

[0110] If the clothing handling device is used for a long time, it can cause problems such as aging of the communication cables and electric sparks at the cable contacts. If the door hook 3 is not positioned accurately when it enters the lock hole 21 and is locked, it can also cause electric sparks. All of these factors can easily cause a fire that burns the clothing handling device, or even cause a house fire. Once a fire occurs, the economic losses are enormous. Therefore, the protective shell 1 is made of fire-resistant material. Preferably, the body 11 and / or cover 12 of the protective shell 1 are sheet metal parts, which are not only easy to roll and form, but also prevent flames inside the door lock cylinder 2 from quickly escaping and burning the front flange 5 of the machine body.

[0111] A washing machine according to the present invention is equipped with a door lock as described above. Typically, the door lock is located opposite the pivot of the door body 4 of the clothes handling device, with the door hook 3 positioned on the door body 4. The protective outer shell 1 and the door lock cylinder 2 are integrally mounted on the front flange 5 of the machine body. The structure of the front flange 5 is similar to that of the first embodiment described above, with the threaded post 52 positioned to match the connection part 14 of the door lock with the protective outer shell 1. This ensures the door lock cylinder 2 is fixed by fixing the protective outer shell 1, maintaining accurate positioning of the door hook 3 and the lock hole 21 over a long period, and preventing jamming or other issues when opening and closing the door.

[0112] Similarly, the door lock cylinder 2 is connected to a communication cable, and a notch 16 is provided on the lower part of the protective housing 1 away from the door body 4, through which the communication cable passes.

[0113] In this way, when a fire occurs, the flames usually burn upwards, avoiding the possibility of flames emerging from the bottom and sides and igniting other flammable materials, thus greatly reducing the risk of fire. Placing the communication cable on the side away from door 4 allows for a simpler cable arrangement utilizing the gaps in the side wall of the clothing handling device, leading directly to the control panel.

[0114] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
