Description

Technical Field

[0001] The utility model belongs to the field of washing boxes of disinfection and cleaning machines, and particularly relates to a noise reduction structure for the washing box of a disinfection and cleaning machine. Background Art

[0002] The structure of a disinfection and cleaning machine is similar to that of a household drum washing machine. A groove is provided at the top of the front side of the disinfection and cleaning machine. A wash box that can be pulled out is provided in the groove. A decorative panel is provided at the outer end of the wash box. Multiple feeding areas are provided in the wash box for placing materials used in cleaning, such as washing liquid, fabric softener, disinfectant, etc., and are respectively put into the cleaning chamber inside the disinfection and cleaning machine at each stage of cleaning. According to customer feedback, since the wash box has a drawer structure and is slidably connected to the casing of the disinfection and cleaning machine, there is a large gap. When the disinfection and cleaning machine operates at high speed during the dehydration stage, high-frequency vibration will be formed, resulting in high-frequency collision between the wash box and the casing, generating collision noise. Although the collision noise is lower in volume than the dehydration noise, the dehydration noise is normal noise that is inevitable during the dehydration operation and will not be considered as noise caused by a malfunction, while the collision noise belongs to abnormal noise and is not inevitable during the dehydration operation and will be considered as noise caused by a malfunction, which is particularly uncomfortable. Content of the Utility Model

[0003] The purpose of the utility model is to provide a noise reduction structure for the wash box of a disinfection and cleaning machine.

[0004] The utility model has the advantage of being able to eliminate the collision noise of the disinfection box.

[0005] [[ID=1:19]]The technical solution of the utility model: A noise reduction structure for the wash box of a disinfection and cleaning machine, including a groove provided on the front side of the cleaning and disinfection machine. A wash box is provided in the groove. A decorative panel is provided on the front side of the wash box. Chutes are provided on both the widthwise sides of the wash box. The rear end of the chute is connected to the rear side wall of the wash box. A cylindrical pin fixed to the side wall of the groove is provided at the front end of the chute. A gap is left between the cylindrical pin and the bottom surface of the chute. A V-shaped anti-drop elastic piece is provided at the rear of the chute. One end of the anti-drop elastic piece is fixed to the bottom surface of the chute. The wash box is magnetically connected to the bottom surface of the groove.

[0006] In the aforesaid noise reduction structure for the wash box of a disinfection and cleaning machine, a first magnet is inlaid on the bottom surface at the rear of the wash box. The lower end of the first magnet extends beyond the bottom surface of the wash box and is provided with a rubber sleeve. A second magnet inlaid on the bottom surface of the groove is provided below the first magnet. The top surface of the second magnet is flush with the bottom surface of the groove.

[0007] In the aforesaid noise reduction structure for the wash box of a disinfection and cleaning machine, a third magnet is inlaid on the bottom surface at the front side of the groove. The top surface of the third magnet is flush with the bottom surface of the groove. The connection line between the second magnet and the third magnet is parallel to the pulling direction of the wash box.

[0008] In the sound insulation structure of the washing box of the aforesaid disinfection and cleaning machine, the first magnet, the second magnet and the third magnet are all cylindrical and have the same diameter and thickness.

[0009] In the sound insulation structure of the washing box of the aforesaid disinfection and cleaning machine, the distance between the anti - detachment elastic piece and the cylindrical pin is matched with the distance between the second magnet and the third magnet. When the washing box is pulled out and the first magnet is attracted to the third magnet, the front end of the anti - detachment elastic piece is deformed by the extrusion of the cylindrical pin.

[0010] In the sound insulation structure of the washing box of the aforesaid disinfection and cleaning machine, a pull - out plate is arranged on the front side of the decorative panel, and a pull - out groove with a downward opening is formed between the pull - out plate and the decorative panel.

[0011] In the sound insulation structure of the washing box of the aforesaid disinfection and cleaning machine, an avoidance groove corresponding to the anti - detachment elastic piece is arranged on the bottom surface of the sliding groove.

[0012] Compared with the prior art, in the present utility model, sliding grooves are arranged on both sides of the existing disinfection box, cylindrical pins matched with the sliding grooves are arranged in the grooves, the front end of the disinfection box is restricted by the cylindrical pins, and magnets are arranged at the rear end of the disinfection box and at the corresponding positions of the grooves, so that the disinfection box is magnetically connected to the bottom surface of the groove, restricting the rear end of the disinfection box. Thus, the disinfection box is firmly fixed in the groove and will not generate collision noise due to vibration force during the dehydration stage of the disinfection and cleaning machine. Therefore, the present utility model has the advantage of being able to eliminate the collision noise of the disinfection box.

[0013] In addition, by arranging an anti - detachment elastic piece in the sliding groove and a third magnet on the bottom surface of the groove, the washing box is restricted after being pulled out a certain length, avoiding accidental complete extraction, which is convenient for users. However, when a relatively large pulling force is applied, the washing box can still be completely pulled out, facilitating the maintenance or replacement in case of failure of the washing box.

[0014] By inlaying the second magnet and the third magnet into the bottom surface of the groove, the bottom surface of the groove is kept flat, ensuring smooth pulling of the washing box. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments, but it shall not be used as a basis for limiting the present utility model.

[0019] Embodiment. The noise reduction structure of the washing box of the disinfection and cleaning machine is as Figure 1 shown, including a groove 1 provided on the front side of the cleaning and disinfection machine. A washing box 2 is provided in the groove 1. A decorative panel 3 is provided on the front side of the washing box 2. A ring groove 13 cooperating with the decorative panel 3 is provided on the front side of the groove 1. The decorative panel 3 is fitted in the ring groove 13. The features are as follows:

[0020] Sliding grooves 4 are provided on both the widthwise sides of the washing box 2. The rear ends of the sliding grooves 4 are connected to the rear side wall of the washing box 2. Cylindrical pins 5 fixed to the side wall of the groove 1 are provided at the front ends of the sliding grooves 4. A gap is left between the cylindrical pins 5 and the bottom surface of the sliding grooves 4. A V-shaped anti-detachment elastic piece 6 is provided at the rear part of the sliding grooves 4. One end of the anti-detachment elastic piece 6 is fixed to the bottom surface of the sliding grooves 4. An avoidance groove 13 corresponding to the anti-detachment elastic piece 6 is provided on the bottom surface of the sliding grooves 4. The washing box 2 is magnetically connected to the bottom surface of the groove 1.

[0021] A first magnet 7 is embedded on the bottom surface at the rear side of the washing box 2. The lower end of the first magnet 7 extends beyond the bottom surface of the washing box 2 and is provided with a thin-walled rubber sleeve 8. A second magnet 9 embedded on the bottom surface of the groove 1 is provided below the first magnet 7. The axis of the second magnet 9 is located at the rear side of the axis of the first magnet 7. The top surface of the second magnet 9 is flush with the bottom surface of the groove 1.

[0022] A third magnet 10 is embedded on the bottom surface at the front side of the groove 1. The top surface of the third magnet 10 is flush with the bottom surface of the groove 1. The connection line between the second magnet 9 and the third magnet 10 is parallel to the pulling direction of the washing box 2.

[0023] The first magnet 7, the second magnet 9 and the third magnet 10 are all cylindrical and have the same diameter and thickness. The first magnet 7, the second magnet 9 and the third magnet 10 are actually the same part, which facilitates the preparation of materials in the factory.

[0024] The distance between the anti-detachment elastic piece 6 and the cylindrical pin 5 is matched with the distance between the second magnet 9 and the third magnet 10. When the washing box 2 is pulled out and the first magnet 7 is attracted to the third magnet 10, the front end of the anti-detachment elastic piece 6 is deformed by the extrusion of the cylindrical pin 5.

[0025] A pull plate 11 is provided on the front side of the decorative panel 3. A pull slot 12 with an opening downward is formed between the pull plate 11 and the decorative panel 3.

[0026] Working principle: Figure 1In the shown case, the washing box 2 is not pulled out. The second magnet 9 exerts a downward pulling force on the first magnet 7, fixing the rear part of the washing box 2 by magnetic force so that it will not move up and down, forward and backward, left and right. The front part of the washing box 2 is fixed by the cylindrical pin 5 and will not move up and down. At the same time, since the second magnet 9 is located at the rear side of the first magnet 7, the second magnet 9 not only exerts a downward pulling force on the first magnet 7 but also a backward pulling force on the first magnet 7, connecting the front part of the washing box 2 to the bottom surface of the annular groove 13 through the decorative panel 3, and the front part of the washing box 2 will not move forward and backward, left and right either. Thus, multiple degrees of freedom of the washing box 2 are restricted, and it is well fixed in the groove 1 and will not make collision noises during the dehydration stage of the disinfection and cleaning machine.

[0027] When the washing box 2 is pulled out through the pull plate 11, since the second magnet 9 and the third magnet 10 do not exceed the bottom surface of the groove 1, the washing box 2 can be smoothly pulled out. During the pulling-out process, the cylindrical pin 5 first contacts the anti-disengagement elastic piece 6, and then the first magnet 7 and the third magnet 10 are coaxial. The front end of the anti-disengagement elastic piece 6 is slightly deformed. At this time, it reaches the limit pulling-out position under normal use conditions, and a greater force is required to continue pulling the washing box 2. When pulling strongly continuously, the protruding part of the anti-disengagement elastic piece 6 is hidden in 13, the cylindrical pin 5 can cross the anti-disengagement elastic piece 6, and the washing box 2 can be taken out from the groove 1, which is convenient for maintenance.

[0028] It needs to be explained that the reason why there is a gap between the existing washing box 2 and the groove 1 is that the washing box 2 is formed by injection molding, the casing material forming the groove 1 is also formed by injection molding, and both the washing box 2 and the casing are thin-walled structures with relatively large volumes, resulting in relatively large injection molding deformation. In order to facilitate the smooth loading and pulling of the washing box 2, the washing box 2 and the groove 1 can only be set as an interference fit, which leads to the washing box 2 shaking in the groove 1 and generating collision noises.

[0029] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.
