Description

Technical Field

[0001] This utility model belongs to the field of washing machine technology, specifically relating to a device for complete discharge of residual water and wastewater and foreign object alarm for drum washing machines. Background Technology

[0002] After completing the washing cycle, front-loading washing machines need to drain the wastewater through a drainage system. However, existing drainage solutions generally suffer from the following significant drawbacks:

[0003] Significant residual water: Conventional drain pumps rely primarily on gravity or simple pumping principles to remove the main wastewater from the washing machine drum. However, they struggle to completely drain residual water from inside the drain pipes (such as U-shaped or horizontally arranged drain pipes, connecting pipes, and T-joints) and from the recessed areas at the bottom of collection devices (such as the collection platform where the lint filter is located). This accumulated wastewater not only becomes a breeding ground for bacteria and mold, producing unpleasant odors and affecting the cleanliness of clothes, but it can also corrode the internal structure of the pipes, shortening the lifespan of the equipment.

[0004] Ineffective treatment of sewage within pipes: Existing drainage systems are primarily designed for discharging sewage from inner cylinders, lacking a proactive mechanism for removing residual sewage from within the drainage pipes themselves (such as inlet pipes, sewage pipes, and delivery pipes). After shutdown, the residual sewage in these pipes will also decompose and become a hygiene hazard.

[0005] Passive handling of foreign object blockage: Although washing machines are usually equipped with filters (such as lint collectors) to intercept foreign objects, current technology lacks effective real-time monitoring and active alarm functions for foreign object blockage. Users often only realize the need to clean the filter after discovering poor drainage, machine errors, or even malfunctions, leading to delayed maintenance, affecting the user experience, and potentially causing equipment damage (such as drain pump overload) due to failure to detect serious blockages in time.

[0006] Insufficient sealing reliability: Conventional sealing methods may not be reliable enough at connection points (such as the interface between the drain pipe and the collection platform), especially when subjected to negative pressure extraction, which can easily lead to leakage. This not only affects the drainage and subsequent residual water extraction effect, but may also cause sewage leakage to contaminate the machine's interior or the environment. Utility Model Content

[0007] The purpose of this invention is to provide a device for the complete discharge of residual water and wastewater and an alarm for foreign objects in a drum washing machine, in order to solve the problems mentioned in the background art.

[0008] The front-loading washing machine features a complete drainage system for wastewater and a foreign object alarm, including:

[0009] Collection station;

[0010] An extraction assembly is located on the outer wall of the collection platform. The extraction assembly includes a sewage pipe, a pressurization shell, a drain pipe, a connecting pipe, a tee pipe, an extraction pump, a delivery pipe, a water inlet pipe, an extraction hole, and fan blades. The sewage pipe is embedded at the top of the outer wall of the collection platform. The pressurization shell is connected to the sewage pipe. The fan blades are rotatably embedded in the inner wall of the pressurization shell. The drain pipe is connected to the pressurization shell. The water inlet pipe is connected to the sewage pipe. The delivery pipe is connected to the collection platform. Two connecting pipes are respectively fitted onto the outer walls of both ends of the tee pipe. One connecting pipe is connected to the delivery pipe, and the remaining connecting pipe is connected to the extraction pump. The extraction hole is located at the bottom of the inner wall of the sewage pipe, and the sewage pipe is connected to the collection platform through the extraction hole.

[0011] Furthermore, a drain pump is fixedly installed on the outer wall of the pressurization housing, and the output end of the drain pump is embedded in the inner wall of the fan blade through the pressurization housing.

[0012] Furthermore, clamps are fitted onto the outer walls of both ends of the sewage pipe and the collection platform.

[0013] Furthermore, a photoelectric switch is embedded in an opening on one side of the outer wall of the collection platform.

[0014] Furthermore, a filter screen is embedded in the bottom opening of the inner wall of the collection platform.

[0015] Furthermore, a sealing layer is bonded to the top of the outer wall of the collection platform, and the sealing layer is attached to the bottom of the outer wall of the drain pipe.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] By integrating three functions—pressurized drainage, negative pressure residual water extraction, and foreign object detection alarm—the system significantly improves wastewater discharge efficiency and equipment reliability. During the regular drainage phase, the drain pump drives the fan blades to pressurize and quickly discharge a large amount of wastewater through the inlet and outlet pipes. After shutdown, the extraction pump automatically starts to generate negative pressure, which thoroughly removes residual water from the collection platform, drain pipe, and inlet pipe through the tee pipe, connecting pipe, and conveying pipe, effectively preventing the growth of bacteria from accumulated water. At the same time, the filter status is monitored in real time by a photoelectric switch. When foreign objects obstruct the filter and cause changes in reflected light, an audible and visual alarm with a buzzer and LED warning light is immediately triggered to remind the user to clean it in time. The double fixing design of clamps and sealant ensures a tight seal between the drain pipe and the collection platform, guaranteeing the effectiveness of negative pressure extraction. Overall, the system achieves zero residual water, self-cleaning of pipes, and proactive fault warning, greatly improving the hygiene level and ease of maintenance of the washing machine.

[0026] Please see Figure 1-3 The technical solution provided in this embodiment is as follows:

[0027] The front-loading washing machine features a complete drainage system for wastewater and a foreign object alarm, including:

[0028] Collection station 1;

[0029] The extraction assembly is located on the outer wall of the collection platform 1. The extraction assembly includes a sewage pipe 2, a pressurizing shell 3, a drain pipe 5, a connecting pipe 6, a tee pipe 7, an extraction pump 8, a delivery pipe 102, a water inlet pipe 201, an extraction hole 202, and a fan blade 301. The sewage pipe 2 is embedded at the top of the outer wall of the collection platform 1. The pressurizing shell 3 is connected to the sewage pipe 2. The fan blade 301 is rotatably embedded in the inner wall of the pressurizing shell 3. The drain pipe 5 is connected to the pressurizing shell 3. The water inlet pipe 201 is connected to the sewage pipe 2. The delivery pipe 102 is connected to the collection platform 1. Two connecting pipes 6 are respectively sleeved on the outer walls of both ends of the tee pipe 7. One connecting pipe 6 is connected to the delivery pipe 102, and the other connecting pipe 6 is connected to the extraction pump 8. The extraction hole 202 is opened at the bottom of the inner wall of the sewage pipe 2. The sewage pipe 2 and the collection platform 1 are connected through the extraction hole 202.

[0030] In a specific embodiment of this utility model, the extraction component involves embedding the drain pipe 5 of an existing washing machine at the top of the outer wall of the collection platform. After applying sealant to the sealing layer 103, two clamps 101 are fitted onto the outer walls of both ends of the drain pipe 2, ensuring that the extraction hole 202 of the drain pipe 2 faces the opening at the top of the collection platform 1. Simultaneously, glue seals the gap between the collection platform 1 and the drain pipe 2 to prevent water leakage. During drainage, the inlet pipe 201 supplies water, and the drain pump 4 and fan blades 301 pressurize and extract the water. Water extraction is completed through the inlet pipe 201 and the drain pipe 5. After shutdown, a large amount of water remains inside the drain pipe 2, the inlet pipe 201, and the conveying pipe 102. At this time, the extraction pump 8 generates negative pressure, and through continuous... Pipe 6, conveying pipe 102, and tee pipe 7 transmit negative pressure to the inside of the collection platform 1. Through the extraction hole 202, negative pressure extraction is completed. After the sewage is filtered through the filter screen 10, it is discharged through the output end of the extraction pump 8. Through the photoelectric switch 9 and external electrical equipment, it is connected to an external relay, LED warning light, and buzzer to realize the monitoring function. The photoelectric switch 9 emits infrared light. When the light encounters foreign objects on the filter screen, the intensity of the reflected light changes. The presence of foreign objects is determined by detecting the change in the intensity of the reflected light. When the change exceeds a preset threshold, an alarm is triggered. When a foreign object is detected, the buzzer sounds intermittently and the LED warning light flashes to remind the user to clean it. The alarm continues until the foreign object is removed or the user manually cancels it.

[0031] Specifically, a drain pump 4 is fixedly installed on the outer wall of the pressurization housing 3, and the output end of the drain pump 4 penetrates the pressurization housing 3 and is embedded in the inner wall of the fan blade 301.

[0032] In a specific embodiment of this utility model, the output end of the drainage pump 4 is embedded in the inner wall of the fan blade 301 through the booster housing 3, which can ensure the stability of the transmission.

[0033] Specifically, clamps 101 are fitted on the outer walls of both ends of the sewage pipe 2 and the collection platform 1.

[0034] In a specific embodiment of this utility model, the clamp 101 can ensure stable positioning of the sewage pipe 2.

[0035] Specifically, a photoelectric switch 9 is embedded in an opening on one side of the outer wall of the collection platform 1.

[0036] In a specific embodiment of this utility model, the photoelectric switch 9 can conveniently detect the condition of the filter screen 10.

[0037] Specifically, a filter screen 10 is embedded in the bottom opening of the inner wall of the collection platform 1.

[0038] In a specific embodiment of this utility model, the filter screen 10 can prevent debris from entering.

[0039] Specifically, a sealing layer 103 is bonded to the top of the outer wall of the collection platform 1, and the sealing layer 103 is attached to the bottom of the outer wall of the drain pipe 2.

[0040] In a specific embodiment of this utility model, the sealing layer 103 is attached to the bottom of the outer wall of the drain pipe 2 to ensure sealing.

[0041] Working principle:

[0042] The extraction assembly involves embedding the existing washing machine's drain pipe 5 into the top of the outer wall of the collection platform 1. After applying sealant to the sealing layer 103, two clamps 101 are fitted onto the outer walls of both ends of the drain pipe 2, ensuring that the extraction hole 202 of the drain pipe 2 faces the opening at the top of the collection platform 1. Simultaneously, glue is applied to seal the gap between the collection platform 1 and the drain pipe 2 to prevent water leakage. During drainage, the inlet pipe 201 supplies water, and the drain pump 4 and fan blades 301 pressurize and extract the water. Water extraction is completed through the inlet pipe 201 and drain pipe 5. After shutdown, a large amount of water remains inside the drain pipe 2, inlet pipe 201, and conveying pipe 102. At this time, a negative pressure is generated by the extraction pump 8, and water is extracted through the connecting pipe 6 and conveying pipe. 102 and the three-way pipe 7 transmit negative pressure to the inside of the collection platform 1. Through the extraction hole 202, negative pressure extraction is completed. After the sewage is filtered through the filter screen 10, it is discharged through the output end of the extraction pump 8. Through the photoelectric switch 9 and external electrical equipment, it is connected to an external relay, LED warning light and buzzer to realize the monitoring function. The photoelectric switch 9 emits infrared light. When the light encounters foreign objects on the filter screen, the intensity of the reflected light changes. The presence of foreign objects is determined by detecting the change in the intensity of the reflected light. When the change exceeds the preset threshold, an alarm is triggered. When a foreign object is detected, the buzzer sounds intermittently and the LED warning light flashes to remind the user to clean it. The alarm state continues until the foreign object is removed or the user manually cancels it.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
