Description

Technical Field

[0001] The present invention relates to the technical field of laundry equipment, and particularly to a washing device. Background Art

[0002] Current washing machines are already very common household appliances, liberating people from the trouble of daily laundry, saving a large amount of household time, being deeply loved by people, and gradually becoming a necessity in daily life. However, with the substantial improvement of people's living quality, the attention to health and hygiene in daily life has also increased. People often face the dilemma of not wanting to wash different clothes together, especially small or intimate clothes. For example, people are reluctant to wash close-fitting underwear with outerwear, and it is even more impossible to wash socks with underwear. Washing different clothes together will greatly increase cross-contamination between clothes, bringing potential skin health hazards. Even if using the same large machine to wash in batches, the possibility of cross-contamination has not been eliminated.

[0003] In response to this, traditional washing machines that integrate washing, rinsing, and dehydration usually adopt the principle of centrifugal dehydration, requiring a double-layer barrel structure. The inner barrel rotates at a low speed relative to the outer barrel for washing and at a high speed for dehydration. The overall machine structure is complex, and it is difficult to achieve the operation of changing barrels for multiple washing. If each type of clothing is washed separately using a washing machine, it will obviously face obvious defects such as huge costs, low machine utilization rate, and large space occupation, and at the same time face the embarrassing situation of insufficient water pipe interfaces. Although using laundry disinfectants is also a common practice, it is easy to leave the smell of disinfectants on clothes, and the residual disinfectants will also cause imbalance of the flora in private parts, bringing harm to health. Even among different family members, they may mind washing each other's clothes together. For example, there are differences in the detergents used by men and women. All these situations pose greater challenges to traditional washing machines. Summary of the Invention

[0038] Disclosed herein is a washing device that integrates water inlet, washing, drainage, rinsing, dehydration and disinfection. The washing bin is separable from the main body, realizing one machine with multiple barrels and washing different clothes in separate barrels. Figure 1 It is a structural schematic diagram of a washing device according to an embodiment of the present invention. Figure 2 is Figure 1 An exploded view of the main body 1 and the washing bin 4 of the shown washing device.

[0039] As Figure 1As shown in the figure, the washing device includes a main body 1, a drainage device, a water supply device, and a wash bin 4 separable from the main body 1. Each part of the device is connected through multiple gas pipelines and / or water supply and drainage pipelines that may be provided with valve bodies to realize operations such as water inlet, rotary washing by the agitator, drainage, and squeezing dehydration.

[0040] As Figure 2 shown in the figure, the main body 1 is formed in a substantially cylindrical shape and includes a main body housing 11 and a partition 12 provided inside the main body housing 11. A driving device is provided on the partition 12. By providing the partition 12, the internal space of the main body housing 11 is divided into upper and lower parts. The upper part is opened upward to form a main body bin, and the lower part is used to accommodate the motor 3 in the driving device described later. Specifically, a motor 3 for driving is installed below the partition 12, that is, in the lower part of the internal space of the main body housing 11. The output shaft of the motor 3 extends upward through a through hole formed in the center of the partition 12 to the upper part of the internal space of the main body housing 11 above the partition 12, and a rotation output member 31 is installed at the tip of the output shaft. In addition, a ventilation hole 120 may be formed on the partition 12, whereby the internal space of the main body housing 11 can be communicated up and down.

[0041] In the present invention, a wash bin 4 is detachably provided in the main body bin of the main body 1. The wash bin 4 is formed in a substantially cylindrical shape and includes a flexible and deformable wash bin barrel 41 and a wash bin lid 42 that can be hermetically fastened to the wash bin barrel 41. When the two are fastened up and down, a sealed wash bin chamber B is formed in the wash bin 4 (see the following Figure 5 ), and the wash bin chamber B can accommodate clean water and clothes.

[0042] A stirring device is provided at the bottom of the wash bin barrel 41. The stirring device includes a stirring body 33 rotatably provided inside the wash bin chamber B and a rotary docking member 32 provided outside the wash bin chamber B in a form of connecting the stirring body 33 through a rotating shaft. The rotary docking member 32 is used to transmit the power from the motor 3 through the rotation output member 31. Matching protrusions and recesses are formed on the rotation output member 31 and the rotary docking member 32. When the flexible wash bin barrel 41 drops onto the partition 12 of the main body 1, the rotation output member 31 and the rotary docking member 32 are mutually and fittingly engaged. When the motor 3 operates, torque is transmitted to the stirring body 33 through the cooperation of the rotation output member 31 and the rotary docking member 32. The stirring body 33 may be a disk agitator, which stirs the clothes in the wash bin chamber B during rotation to achieve an effect similar to agitator washing.

[0043] A water inlet 421 and a water outlet 422 of the washing bin are formed on the washing bin cover 42. Among them, the water inlet 421 of the bin is connected to a water supply device through a pipeline to supply clean water into the washing bin 4, and the water outlet 422 of the bin is connected to a drainage device through a pipeline to drain sewage from the washing bin 4. In this embodiment, the water supply device can be a water inlet valve 61, which can be installed on a tap. When the water inlet valve 61 is opened, clean water directly enters the washing bin 4. The drainage device can be a vacuum pump 2. A pump inlet 201 and a pump outlet 202 are provided on the vacuum pump 2. The pump inlet 201 is connected to the water outlet 422 of the bin through a pipeline. When the vacuum pump 2 works, it extracts the sewage in the washing bin 4 and discharges it from the pump outlet 202.

[0044] In addition, the washing device may further include a heating module (not shown). The heating module can be provided on the pipeline through which the water supply device supplies clean water to the washing bin 4 for heating the clean water to soak the clothes for disinfection, or can be provided at the bottom of the washing bin barrel 41 in the form of, for example, a heating plate to heat the clean water in the washing bin 4 to disinfect the clothes.

[0045] The following refers to Figure 1 , Figure 2 to describe in detail the washing process of the washing device. Before washing, the washing bin 4 can be replaced, and the new washing bin 4 is installed from the opening of the main body 1 until the stirring device on the washing bin 4 is combined with the driving device on the main body 1.

[0046] 1) Water inlet: When the water inlet valve 61 is opened, clean water enters the washing bin 4 through the water inlet 421 of the bin.

[0047] 2) Washing: The motor 3 works, and the power is transmitted to the stirring body 33 through the cooperation of the rotating output member 31 and the rotating docking member 32, driving the stirring body 33 to stir the clothes.

[0048] 3) Drainage and dehydration: The motor 3 stops, and the water inlet valve 61 remains closed. The vacuum pump 2 works. The washing bin barrel 41 shrinks and deforms due to the formation of negative pressure, and gradually draws water from the water outlet 422 of the bin through the pipeline to the pump inlet 201 and discharges the sewage from the pump outlet 202. The washing bin barrel 41 shrinks and deforms, and the rotating docking member 32 at the bottom and the rotating output member 31 are separated from each other, thus disconnecting the connection between the motor 3 and the stirring body 33. As a result, the washing bin 4 is separated from the main body 1.

[0049] 4) Dehydration: The water inlet valve 61 remains closed, and the vacuum pump 2 continues to work. The flexible washing bin barrel 41 is further squeezed and deformed under negative pressure, and at the same time squeezes the clothes to dehydrate them.

[0050] 5) Rinsing: The water inlet valve 61 is opened to refill the washing bin 41 with clean water, and the washing bin 41 resumes its original shape. The rotary docking member 32 at the bottom and the rotary output member 31 are re-docked and combined with each other, and the motor 3 is started to drive the agitator 33 to agitate the clothes.

[0051] 6) Drainage and dehydration after rinsing: Repeat the above drainage and dehydration process.

[0052] According to the above structure, the deformable flexible washing bin is compressed and deformed during vacuum suction to achieve internal drainage and squeeze the clothes for dehydration. The bottom of the washing bin is provided with an agitator with a wave wheel structure, and the agitation washing is realized by driving the agitator to rotate. The washing bin can be separated from or replaced with the main body, so that different types of clothes can use different washing bins to avoid cross-contamination between clothes.

[0053] (First variant)

[0054] Figure 3 The first variant of the washing device is shown. As Figure 3 shown, in this variant, in addition to the vacuum pump 2, the drainage device further includes a sewage tank 5 added between the washing bin 4 and the vacuum pump 2.

[0055] Above the sewage tank 5, there are provided a sewage tank suction port 501 and a sewage tank air extraction port 502. The sewage tank suction port 501 is connected to the bin water outlet 422 of the washing bin 4 through a pipeline, and the sewage tank air extraction port 502 is connected to the pump inlet 201 of the vacuum pump 2 through a pipeline. It should be noted that at this time, the pump inlet 201 of the vacuum pump 2 functions as a vacuum pump suction port for extracting air from the sewage tank. In addition, a drain valve 51 is provided below the sewage tank 5, and the drain valve 51 can also be a drain plug, so that the sewage in the sewage tank 5 can be drained electrically or manually.

[0056] According to the above structure, by adding a sewage tank between the vacuum pump and the washing bin, the washing bin can be indirectly suctioned by suctioning the sewage tank, so that sewage can be prevented from passing through the vacuum pump, thereby preventing the vacuum pump from being blocked or damaged by impurities in the sewage.

[0057] (Second variant)

[0058] Figure 4 The second variant of the washing device is shown. As Figure 4 shown, in this variant, a clean water tank 6 for storing clean water for washing is provided as the water supply device. Below the clean water tank 6, there is a water inlet valve 61, and its water outlet is connected to the bin water inlet 421 of the washing bin 4 through a pipeline. In addition, similar to the first variant, a sewage tank 5 for accumulating sewage is also added between the washing bin 4 and the vacuum pump 2.

[0059] By providing a clean water tank 6, the requirements for the application scenarios of the washing device can be easily reduced, and the use of the washing device becomes more flexible, no longer restricted by existing water pipes. Before use, only an appropriate amount of clean water needs to be filled into the clean water tank 6 and set at a position higher than the washing bin 4. Since both the clean water tank 6 and the sewage tank 5 can be separated from the main body, it is convenient to perform mobile water injection or drainage for the clean water tank 6 and the sewage tank 5.

[0060] In addition, on the basis of providing the clean water tank 6, a water pump can be added to the water supply device, so that clean water can enter the washing bin 4 without relying on gravity.

[0061] (Third modification example)

[0062] Figure 5 The third modification example of the washing device is shown. As Figure 5 shown, in this modification example, the washing device has been further modified on the basis of providing the sewage tank 5 and the clean water tank 6.

[0063] Specifically, the washing bin 4 forms a sealed washing bin chamber B inside by fastening the washing bin barrel 41 and the washing bin cover 42. At the same time, the washing bin 4 is also configured to be hermetically fastened to the opening provided in the main body 1, so that a sealed main body chamber A is formed between the inner wall of the main body 1 and the outer wall of the washing bin barrel 41. As a form, the washing bin barrel 41 of the washing bin 4 may be formed with a flange protruding outward in the circumferential direction at the opening, and a groove corresponding to the upper end edge of the main body housing 11 is formed on the flange. The washing bin 4 is embedded in the main body 1 in such a way that the upper end edge of the main body housing 11 is embedded in the groove of the washing bin barrel 41, thereby forming a sealed main body chamber A. In addition, a sealing ring or the like may be provided on the flange of the washing bin barrel 41.

[0064] Above the sewage tank 5, in addition to the sewage tank suction port 501 and the sewage tank air extraction port 502, a sewage tank ventilation hole 503 is also provided. Correspondingly, a ventilation hole 120 is provided on the partition 12 of the main body 1, and a communication valve 13 is provided below the ventilation hole 120. The communication valve 13 may be a two-position three-way air valve, which can connect the main body chamber A to the atmosphere or connect the ventilation hole 503 of the sewage tank 5 through a pipeline.

[0065] The automatic water addition and drainage dehydration of the washing device are carried out in the following manner.

[0066] 1) Automatic water addition to the washing chamber: Open the water inlet valve 61, and the water inlet of the chamber 421 is connected to the bottom of the clean water tank 6 through a pipeline. Control the communication valve 13 to connect the ventilation hole 120 of the main body 1 with the sewage tank 5. In other words, at this time, both the main body chamber A of the main body 1 and the washing chamber B of the washing chamber 4 are connected to the sewage tank 5 and the vacuum pump 2. Start the vacuum pump 2, and negative pressure is generated in both the washing chamber B and the main body chamber A. Therefore, the clean water in the clean water tank 6 is sucked into the washing chamber.

[0067] 2) Automatic drainage and dehydration of the washing chamber: Close the water inlet valve 6, control the communication valve 13 to connect the ventilation hole 120 of the main body 1 with the atmosphere, and keep the pressure in the main body chamber A at atmospheric pressure. Start the vacuum pump 2, and negative pressure is generated in both the sewage tank 5 and the washing chamber 4, while the pressure in the main body chamber A remains at atmospheric pressure. Therefore, the flexible washing chamber barrel 41 is gradually compressed and deformed, and the washed sewage is sucked into the sewage tank, and finally the laundry is squeezed to dehydrate it.

[0068] On the other hand, the washing device realizes the docking and detachment of the stirring device of the washing chamber 4 and the driving device of the main body 1 in the following way.

[0069] 1) Detachment: Only when the vacuum pump 2 is working and the communication valve 13 is controlled to connect the main body chamber A of the main body 1 with the atmosphere, the pressure in the washing chamber B is negative and the air pressure is less than that in the main body chamber A. Therefore, the washing chamber barrel 41 is compressed and deformed and shrinks, and the rotating docking member 32 and the rotating output member 31 are detached from each other.

[0070] 2) Docking: Control the communication valve 13 to connect the main body 1 with the sewage tank 5. There is no air pressure difference between the main body chamber A and the washing chamber B. The bottom of the washing chamber 4 remains in a natural hanging state, and the rotating docking member 32 and the rotating output member 31 always remain docked.

[0071] According to this structure, only one driving part, that is, the vacuum pump 2, is used to realize low-water-level water inlet. No water pump is required. The vacuum pump 2 can be used for both water inlet and drainage, and can realize washing operations at low water levels with a simple structure.

[0072] (Fourth modification example)

[0073] Figure 6 Shows a fourth modification example of the washing device.

[0074] As Figure 6As shown, in this modified example, the washing device has a water tank 7, and a deformable flexible diaphragm 70 is provided inside the water tank 7. The flexible diaphragm 70 divides the water tank 7 into two chambers on the left and right, forming a clean water tank 71 as part of the water supply device and a sewage tank 72 as part of the drainage device. In other words, the clean water tank 71 and the sewage tank 72 are integrally provided in the water tank 7. The total volume of the clean water tank 71 and the sewage tank 72 is constant, and their respective volumes increase and decrease according to the shape of the flexible diaphragm 70. In addition, a water pump 8 is also provided between the clean water tank 71 and the main body 1.

[0075] An inlet plug 711 and a clean water tank vent 712 are provided above the clean water tank 71, and a clean water tank outlet 713 is formed below it. The water pump inlet 801 of the water pump 8 is connected to the clean water tank outlet 713 through a pipeline, and the water pump outlet 802 is connected to the bin inlet 421 of the washing bin 4 through a pipeline.

[0076] On the other hand, a sewage tank suction port 722 and a sewage tank air extraction port 723 are formed above the sewage tank 72, and a drain plug 721 is provided below it. The pump inlet 201 of the vacuum pump 2 is connected to the sewage tank air extraction port 723 of the sewage tank 72 through a pipeline, and the air extracted from the sewage tank 72 is discharged from the pump outlet 202.

[0077] In this modified example, the clean water tank vent 712 of the clean water tank 71 and the sewage tank suction port 722 of the sewage tank 72 are also connected through a pipeline, and a branch is also connected from this pipeline to the bin outlet 422 of the washing bin 4. In other words, this pipeline can be a three-way pipeline connected to the clean water tank 71, the sewage tank 72, and the washing bin 4 respectively. An air valve 73 is provided at the branch of this pipeline. The air valve 73 can be a two-position two-way air valve, which is used to make the sewage tank suction port 722, the clean water tank vent 712, and the bin outlet 422 communicate with the atmosphere controllably, so as to function as a pressure relief valve.

[0078] The washing device realizes the washing process in the following way.

[0079] 1) Before the start of washing, open the air valve 73 and inject enough clean water into the clean water tank 71 through the inlet plug 711. At this time, the air in the clean water tank 71 and the sewage tank 72 is discharged from the air valve 73. As the clean water gradually enters the clean water tank 71, the flexible diaphragm 70 continuously squeezes the space of the sewage tank 72 to the right.

[0080] 2) Water inlet: The water pump 8 works to pump the clean water in the clean water tank 71 into the washing bin barrel 41. The flexible diaphragm 70 gradually recovers as the clean water is discharged, and air enters the sewage tank 72 through the air valve 73.

[0081] 3) Washing: The water pump 8 stops, and the motor 3 works to drive the agitator 33 to agitate the clothes.

[0082] 4) Drainage: The air valve 73 remains closed, the vacuum pump 2 operates to extract air, and the sewage is extracted from the bin water outlet 422 and enters the sewage tank 73.

[0083] 5) Dehydration: The air valve 73 remains closed, the vacuum pump 2 continues to operate, and the flexible washing bin 41 is further squeezed and deformed to squeeze the clothes for dehydration.

[0084] 6) After the washing is completed, open the drain plug 721 of the water tank 72 to drain the water.

[0085] By setting the clean water tank and the sewage tank as a whole and arranging a flexible diaphragm between the two, the volumes of the two can be mutually converted, thus greatly reducing the floor area of the washing device.
