Description

Technical Field

[0001] This invention belongs to the field of washing equipment technology, specifically, it relates to an ultrasonic cleaning device and washing equipment for washing equipment. Background Technology

[0002] "Washing equipment" refers to a general term for household appliances with washing functions, such as washing machines and washer-dryer combos. "Ultrasonic cleaning device of washing equipment" refers to a device installed on washing equipment for ultrasonic pre-washing of clothes (i.e., pre-washing heavily soiled areas of large garments with ultrasonic waves before the main wash).

[0003] The ultrasonic cleaning unit of the washing equipment contains washing water containing detergent, which is used to ultrasonically clean the clothes. The ultrasonic cleaning unit is equipped with a drain outlet for discharging the washing water, which is connected to the drainage pipe of the washing equipment. After ultrasonic cleaning, the washing water can be directly discharged into the drainage pipe through the drain outlet, and then discharged out of the washing equipment.

[0004] In the above methods, the washing water in the ultrasonic cleaning device can only be discharged outside the washing equipment after it is used up, and cannot be recycled. In particular, for washing water containing high concentrations of detergent, direct discharge will result in waste of detergent.

[0005] In view of this, the present invention is hereby proposed. Summary of the Invention

[0006] The purpose of this invention is to provide an ultrasonic cleaning device for washing equipment, so as to make full use of the washing water in the ultrasonic cleaning device and avoid the waste of detergent.

[0007] Another object of the present invention is to provide a washing device that achieves high utilization of detergent.

[0008] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0009] An ultrasonic cleaning device for a washing machine includes a cleaning tank for containing washing water, a drain outlet at the bottom of the cleaning tank that connects the inside and outside of the cleaning tank, and an opening and closing component that is slidably disposed on the cleaning tank for opening and closing the drain outlet.

[0010] Furthermore, the cleaning tank includes a bottom wall and front and rear end side walls in opposite positions, and the drain outlet is spaced from the front and rear end side walls and is formed on the bottom wall.

[0011] Furthermore, the bottom wall of the cleaning tank is partially raised towards the inside of the cleaning tank to form a boss structure. The boss structure has a boss sidewall that is perpendicular to the plane where the bottom wall of the cleaning tank is located, opposite to and close to the rear sidewall of the cleaning tank, and the drain outlet is opened on the boss sidewall.

[0012] Furthermore, the opening and closing component includes:

[0013] A sliding frame is slidably disposed on the outer side of the bottom wall of the cleaning tank and can slide from the rear end of the cleaning tank to the front end of the cleaning tank.

[0014] A sealing element is disposed on the sliding frame, opposite to the drain outlet, and locked between the front side wall of the cleaning tank and the drain outlet, for opening and closing the drain outlet.

[0015] Furthermore, a protrusion structure is provided on the outer wall surface of the bottom wall of the cleaning tank, which is located between the drain outlet and the rear side wall of the cleaning tank, and the sliding frame is elastically connected to the protrusion structure through an elastic element.

[0016] Furthermore, the outer wall surface of the bottom wall of the cleaning tank has a groove that is recessed into the cleaning tank and extends from the drain outlet to the rear side wall of the cleaning tank between the drain outlet and the rear side wall of the cleaning tank. The protrusion structure is engaged in the groove, and the elastic element is disposed in the groove, with one end abutting against the protrusion structure and the other end used to connect with the sliding frame.

[0017] Preferably, the elastic element is a spring.

[0018] Furthermore, the protrusion structure has a first and a second sidewall disposed opposite to each other. The first sidewall has an opening that coincides with the drain outlet. The second sidewall is located between the first sidewall and the rear end sidewall of the cleaning tank.

[0019] The present invention also discloses a washing device, including a tub for containing washing water, and an ultrasonic cleaning device as described in any of the above technical solutions. The cleaning tank of the ultrasonic cleaning device is detachably mounted on the tub and can be pulled out into the tub until the drain outlet is located inside the tub.

[0020] Furthermore, an installation chamber is provided on the inner side wall of the barrel, which has an opening facing the inside of the barrel. The cleaning tank and the opening and closing component are disposed in the installation chamber through the opening. After the cleaning tank is pulled out of the installation chamber, the opening and closing component has an open state in which the drain outlet can be slidably opened out of the installation chamber.

[0021] Furthermore, the washing equipment also includes:

[0022] A drain tray is disposed within the mounting cavity and sleeved on the outside of the cleaning tank. The cleaning tank slides back into the mounting cavity, and the opening and closing mechanism opens the drain outlet, which communicates with the drain tray.

[0023] A drain pipe is used to drain the washing water from the washing equipment, and the drain pan is connected to the drain pipe.

[0024] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0025] In this invention, the drain outlet is located at the bottom of the washing tank, and the bottom of the washing tank can be pulled into the tub of the washing equipment. When the opening and closing mechanism slides open the drain outlet, the washing water in the washing tank can be discharged into the tub through the drain outlet at the bottom of the washing tank. This part of the washing water can further participate in the washing process in the tub, realizing full utilization of the washing water discharged from the washing tank and avoiding the waste of detergent in the washing water.

[0026] In this invention, when the bottom of the washing tank is not pulled into the tub of the washing equipment, its drain outlet can be connected to the drain pipe of the washing equipment to discharge the washing water outside the washing equipment.

[0027] In this invention, when the washing tank is pulled out into the tub until the drain outlet is inside the tub, the user can slide the opening and closing mechanism to open the drain outlet, allowing the washing water in the washing tank to be discharged into the tub and participate in the washing process inside the tub. This fully utilizes the washing water discharged from the washing tank, improves the washing effect of the washing equipment, and avoids the waste of water and detergent resources.

Therefore, they should not be construed as limiting this invention.

[0044] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0045] "Washing equipment" refers to a general term for household appliances with washing functions, such as washing machines and washer-dryer combos. "Ultrasonic cleaning device of washing equipment" refers to a device installed on washing equipment that uses ultrasonic waves to pre-wash the clothes to be washed (i.e., pre-washing the heavily soiled parts of large garments with ultrasonic waves before the main wash).

[0046] like Figures 1 to 9 As shown, this invention discloses an ultrasonic cleaning device for washing equipment. The ultrasonic cleaning device includes a cleaning tank 1 for containing washing water. The cleaning tank 1 includes a bottom wall 14 and peripheral side walls, which together form the cleaning tank 1.

[0047] The washing tank 1 is provided with a drain outlet 13 that connects the inside and outside of the washing tank 1, for draining the washing water in the washing tank 1. The drain outlet 13 can be provided at the bottom or on the side wall of the washing tank 1. In this invention, the drain outlet 13 is provided at the bottom of the washing tank 1.

[0048] The ultrasonic cleaning device also includes an opening and closing component 2, which is slidably disposed on the cleaning tank 1 for opening and closing the drain outlet 13. Specifically, the opening and closing component 2 can be disposed on the inner side or the outer side of the cleaning tank 1, preferably disposed on the outer side of the cleaning tank 1.

[0049] In this invention, the drain outlet 13 is located at the bottom of the washing tank 1. The bottom of the washing tank 1 can be pulled into the tub of the washing equipment. When the opening and closing component 2 slides open the drain outlet 13, the washing water in the washing tank 1 can be discharged into the tub through the drain outlet 13. This part of the washing water can further participate in the washing process in the tub, realizing the full utilization of the washing water discharged from the washing tank 1 and avoiding the waste of detergent in the washing water.

[0050] In this invention, when the opening / closing component 2 does not open the drain outlet 13, the washing water in the washing tank 1 can be used for ultrasonic washing of clothes. Furthermore, when the bottom of the washing tank 1 is not pulled into the tub of the washing equipment, its drain outlet 13 can be connected to the drain pipe of the washing equipment to discharge the washing water outside the washing equipment.

[0051] As one embodiment of the present invention, such as Figure 3 As shown, the cleaning tank 1 includes a bottom wall 14 and a front side wall 11 and a rear side wall 12 located opposite each other. The drain outlet 13 is spaced from the front side wall 11 and the rear side wall 12 and is formed on the bottom wall 14.

[0052] Specifically, the drain outlet 13 is located in the middle area between the front side wall 11 and the rear side wall 12. A handle is provided on the outer wall surface of the front side wall 11, allowing the user to pull out the washing tank 1 by holding the handle. The bottom wall 14, at least at the location where the drain outlet 13 is located, can be pulled out into the tub of the washing equipment.

[0053] In this embodiment, there is a gap between the drain outlet 13 and the front side wall 11 and the rear side wall 12. In this way, the rear side wall 12 can be locked onto the tub to connect the washing tank 1 to the tub, preventing the washing tank 1 from falling off the tub. The area on the bottom wall 14 where the drain outlet 13 is opened can be pulled into the tub of the washing equipment along with the front side wall 11, so as to realize the purpose of draining the washing water in the washing tank 1 into the tub for secondary use.

[0054] As another embodiment of the present invention, such as Figures 3 to 8 As shown, the bottom wall 14 of the cleaning tank 1 partially protrudes towards the interior of the cleaning tank 1 to form a boss structure 15. The boss structure 15 has a boss side wall 151 that is perpendicular to the plane where the bottom wall 14 of the cleaning tank 1 is located, opposite to and close to the rear end side wall 12 of the cleaning tank 1, and the drain outlet 13 is opened on the boss side wall 151.

[0055] Furthermore, such as Figure 5 As shown, the boss structure 15 is a groove structure on the outside of the bottom wall 14 of the cleaning tank 1. The drain outlet 13 is opened on the side wall of the groove structure and is perpendicular to the plane where the bottom wall 14 is located.

[0056] In this embodiment, the drain outlet 13 is located on the side wall 151 of the boss. When the drain outlet 13 is in the open state, sliding the opening and closing member 2 from the front end of the cleaning tank 1 to the rear end of the cleaning tank 1 can block the drain outlet 13 and prevent the washing water in the cleaning tank 1 from flowing out. Alternatively, when the drain outlet 13 is in the open state, without sliding the opening and closing member 2, the cleaning tank 1 can be pulled out to the front end, which can also block the drain outlet 13.

[0057] Conversely, when the drain outlet 13 is closed, sliding the opening and closing member 2 from the rear end of the cleaning tank 1 to the front end of the cleaning tank 1 can open the drain outlet 13 to drain the washing water in the cleaning tank 1. Alternatively, when the drain outlet 13 is closed, without sliding the opening and closing member 2, but instead resetting the cleaning tank 1 to the rear end, the drain outlet 13 can also be opened.

[0058] As another embodiment of the present invention, such as Figure 1 , Figure 2 , Figures 5 to 7 As shown, the opening / closing component 2 includes:

[0059] The sliding frame 21 is slidably disposed on the outer side of the bottom wall 14 of the cleaning tank 1, i.e., the outer wall surface 141 of the bottom wall, and can slide from the rear end of the cleaning tank 1 to the front end of the cleaning tank 1.

[0060] A sealing element 22 is disposed on the sliding frame 21, opposite to the drain outlet 13, and engaged between the front side wall 11 of the cleaning tank 1 and the drain outlet 13, for opening and closing the drain outlet 13. The sealing element 22 may be a rubber ring structure, the size and shape of which match the drain outlet 13, enabling it to seal the drain outlet.

[0061] In this embodiment, the drain outlet 13 is located on the side wall 151 of the boss, so that when the drain outlet 13 is in the open state, there is a gap between the sealing member 22 and the drain outlet 13. At this time, when the sliding frame 21 is slid from the front end of the cleaning tank 1 to the rear end of the cleaning tank 1, the sealing member 22 can slide towards the drain outlet 13 to block the drain outlet 13. Alternatively, when the drain outlet 13 is in the open state, the sliding frame 21 is kept stationary, and the cleaning tank 1 is pulled out towards the front end, so that the drain outlet 13 will slide towards the sealing member 22 and be blocked by the sealing member 22.

[0062] Conversely, when the drain outlet 13 is closed, the sealing element 22 blocks the drain outlet 13. At this time, the sliding frame 21 is slid from the rear end of the cleaning tank 1 to the front end of the cleaning tank 1, causing the sealing element 22 to slide towards the front end of the cleaning tank 1 and disengage from the drain outlet 13, thereby opening the drain outlet 13. Alternatively, when the drain outlet 13 is closed, the sliding frame 21 is kept stationary, and the cleaning tank 1 is reset to the rear end, causing the drain outlet 13 to move away from the sealing element 22 and separate from it, thereby opening the drain outlet 13.

[0063] As one embodiment of the present invention, such as Figure 2 and Figure 4As shown, a protrusion structure 3 is provided on the outer wall surface 141 of the bottom wall 14 of the cleaning tank 1. It is located between the drain outlet 13 and the rear side wall 12 of the cleaning tank 1. The sliding frame 21 is elastically connected to the protrusion structure 3 through an elastic element. The elastic element can be a spring 4.

[0064] Specifically, the outer wall surface of the bottom wall 14 of the cleaning tank 1, namely the outer wall surface 141 of the bottom wall, the drain outlet 13 and the rear side wall 12 of the cleaning tank 1, have a groove 142 that is recessed into the cleaning tank 1 and extends from the drain outlet 13 to the rear side wall 12 of the cleaning tank 1. The protrusion structure 3 is engaged in the groove 142. The elastic element is disposed in the groove 142, with one end abutting against the protrusion structure 3 and the other end used to connect with the sliding frame 21.

[0065] More specifically, the sliding frame 21 is provided with a connector 23, which is a columnar structure. The connector 23 is arranged opposite to the sealing member 22, and the central axis of the connector 23 and the sealing member 22 coincides. One end of the spring 4 abuts against the protrusion structure 3, and the other end of the spring 4 is sleeved on the connector 23.

[0066] In this embodiment, when the drain outlet 13 is closed, the sliding frame 21 is slid towards the front end of the washing tank 1, the spring 4 is compressed, and the drain outlet 13 opens to drain the washing water from the washing tank 1. After drainage, the spring 4 returns to its original position, causing the sliding frame 21 to slide towards the rear end of the washing tank 1, thereby automatically sealing the drain outlet 13. Alternatively, when the drain outlet 13 is closed, the sliding frame 21 is kept stationary, and the washing tank 1 is pushed back towards the rear end, the spring 4 is compressed, and the drain outlet 13 opens to drain the washing water from the washing tank 1.

[0067] As one implementation method of this embodiment, such as Figure 2 and Figure 4 As shown, the protrusion structure 3 has a first sidewall 31 and a second sidewall 32 arranged opposite to each other. The first sidewall 31 has an opening 311, which coincides with the drain outlet 13. The second sidewall 32 is located between the first sidewall 31 and the rear end sidewall 12 of the cleaning tank 1. One end of the spring 4 abuts against the second sidewall 32 of the protrusion structure 3, and the other end of the spring 4 is sleeved on the connector 23 of the sliding frame 21.

[0068] In this embodiment, the first sidewall 31 of the protrusion structure 3 has an opening 311, which coincides with the drain outlet 13, allowing the washing water in the washing tank 1 to be discharged through the drain outlet 13 and the opening 311. The second sidewall 32 of the protrusion structure 3 is used to abut against the spring 4, enabling the sliding frame 21 to slide under the force of the spring 4, and further realizing the opening and closing of the drain outlet 13.

[0069] As one embodiment of the present invention, such as Figure 2 As shown, a screw 143 is provided on the outer wall surface 141 of the bottom wall of the cleaning tank 1. The screw 143 is disposed perpendicular to the outer wall surface 141 and is spaced apart from the outer wall surface 141. A sliding groove 25 is provided on the sliding frame 21, extending from the front end to the rear end of the sliding frame 21. The sliding groove 25 is slidably engaged with the screw 143.

[0070] In this embodiment, the slide groove 25 is slidably connected to the screw 143, which plays a role in limiting and orienting the sliding of the slide frame 21. This not only ensures the stability of the sliding direction of the slide frame 21, but also prevents the slide frame 21 from sliding off the cleaning tank 1, thus ensuring the stability of the sliding assembly between the cleaning tank 1 and the slide frame 21.

[0071] The present invention also provides a washing device, including a tub for containing washing water, and an ultrasonic cleaning device as described in any of the above technical solutions. The cleaning tank 1 of the ultrasonic cleaning device is detachably mounted on the tub and can be pulled out into the tub until the drain outlet 13 is located inside the tub.

[0072] In this invention, when the washing tank 1 is pulled out into the tub until the drain outlet 13 is located inside the tub, the sliding opening and closing component 2 opens the drain outlet 13, allowing the washing water in the washing tank 1 to be discharged into the tub and participate in the washing process inside the tub. This fully utilizes the washing water discharged from the washing tank 1, improves the washing effect of the washing equipment, and avoids the waste of water and detergent resources.

[0073] In one embodiment of the present invention, an installation chamber is provided on the inner side wall of the barrel, which has an opening facing the inside of the barrel. The cleaning tank 1 and the opening and closing component 2 are disposed in the installation chamber through the opening. After the cleaning tank 1 is pulled out of the installation chamber, the opening and closing component 2 has an open state in which the drain outlet 13 can be slidably opened out of the installation chamber.

[0074] Specifically, when the user is not using the ultrasonic cleaning device, the ultrasonic cleaning device is located inside the installation chamber and will not interfere with the washing process of the clothes inside the tub. When the user needs to use the ultrasonic cleaning device for ultrasonic washing, first keep the sliding frame 21 of the opening and closing component 2 stationary, hold the front end of the cleaning tank 1, and pull the cleaning tank 1 into the tub. At this time, the drain outlet 13 is in a blocked state and is inside the tub, and ultrasonic washing begins.

[0075] After ultrasonic washing, if the washing water in the cleaning tank 1 contains a high concentration of detergent, the washing water can be drained into the tub for reuse. The specific steps include: moving the handle 24 on the sliding frame 21 so that the sliding frame 21 slides towards the front end of the cleaning tank 1, the sealing part 22 on the sliding frame 21 is separated from the drain outlet 13, the drain outlet 13 is opened, and the washing water in the cleaning tank 1 can flow directly into the tub through the drain outlet 13.

[0076] After ultrasonic washing is completed, if the washing water in the cleaning tank 1 contains a low concentration of detergent and is dirty, the washing water can be discharged outside the washing equipment to avoid contaminating the washing water in the tank.

[0077] Specifically: such as Figure 8 and Figure 9 As shown, the washing equipment includes a drain tray 5, which is disposed within the mounting chamber, sleeved outside the washing tank 1, and located at the lower part of the washing tank 1. When the washing tank 1 slides back into the mounting chamber, the opening / closing member 2 opens the drain outlet 13, and the drain outlet 13 communicates with the drain tray 5. The washing equipment also includes a drain pipe for draining washing water from the washing equipment, and the drain tray 5 communicates with the drain pipe.

[0078] After ultrasonic washing is completed, keeping the sliding frame 21 stationary, push the washing tank 1 back into the installation chamber. The spring 4 compresses, and the drain outlet 13 separates from the sealing member 22. At this time, the drain outlet 13 is located above the drain pan 5, and the washing water flowing out of the drain outlet 13 flows directly into the drain pan 5 and is discharged from the drain pan 5 into the drain pipe of the washing equipment. This setting eliminates the need for a separate drain pipe for the washing tank 1, instead sharing the same drain pipe with the tank body, simplifying the structure of the washing equipment.

[0079] As one implementation method of this embodiment, such as Figure 8 and Figure 9 As shown, the drain tray 5 is fitted onto the bottom of the cleaning tank 1, with the rear end 52 of the drain tray positioned near the rear end of the cleaning tank 1 and the front end 53 positioned near the front end of the cleaning tank 1. The drain tray 5 includes a bottom wall 54, which is inclined downwards from the front end 53 to the rear end 52 of the drain tray.

[0080] This arrangement allows the washing water flowing from drain outlet 13 into drain pan 5 to converge at the rear end 52 of drain pan. Furthermore, the rear end 52 of drain pan is provided with a drain outlet 51 connecting the inside and outside of drain pan 5. Drain outlet 51 connects to the drain pipe of the washing equipment. The washing water flowing into the rear end 52 of drain pan can be quickly and efficiently discharged from drain outlet 51 into the drain pipe and then discharged from the drain pipe to the outside of the washing equipment, improving the drainage efficiency of washing water in the washing tank 1 and preventing the accumulation of washing water in drain pan 5.

[0081] 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. The implementation schemes in the above embodiments can also be further combined or replaced. 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.
