Detailed Description

In the prior art, the dewatering scheme usually adopts a mode of separating an inner barrel from an outer barrel, so that the inner barrel with meshes rotates at a high speed to separate water on the washings from the washings through centrifugal force. However, when the laundry is unevenly distributed in the washing inner tub, the washing inner tub is rotated at a high speed during dehydration to cause abnormal vibration of the machine and generate loud noise; moreover, dirt is easily stored between the inner barrel and the outer barrel, germs are bred, and the health of users is affected. In other related technologies, drying is used to heat and evaporate water in the laundry and then to pump the heated water out, so as to dry the laundry. But the drying mode has certain requirements on the posture of the washed objects after washing, and the drying can be realized only by keeping the washed objects relatively fluffy, so that the size of the washing bin is increased, and the internal structure of the washing bin is more complicated. Therefore, a mode of a flexible inner container and an outer container is adopted, the inner container is pressed inwards by inflating the inner container and the outer container in the process, clothes in the inner container are extruded upwards, and water is discharged through a water discharge pipe at the top. In addition, there is a related art that the squeezing ribs are used to squeeze and dewater the clothes, but the manner needs to continuously rub the clothes, which is easy to cause friction damage.

In order to improve at least one of the disadvantages of the dehydration mode in the related art, the embodiment of the application provides a bag type vacuum extrusion dehydration device and a washing device, wherein the bag type vacuum extrusion dehydration device and the washing device extrude and pump water in washings out of a washing chamber by sucking the soft washing chamber and deforming the washing chamber. The new dehydration mode can not only effectively remove the water in the washings, but also reduce the problems of shaking, noise and the like of the traditional dehydration mode.

FIG. 1 is a schematic view of a bag vacuum press dewatering device 010 before dewatering in one embodiment of the subject application; fig. 2 is a schematic view of the bag-type vacuum squeeze dewatering device 010 in dewatering according to an embodiment of the present application. As shown in fig. 1 and 2, a bag-type vacuum press dewatering device 010 provided by an embodiment of the present application includes a washing tank 100 and a negative pressure assembly 200. The washing compartment 100 comprises a holder 110 and a flexible bag 120, wherein the flexible bag 120 has a bag opening, and the edge of the bag opening is connected to the holder 110, so that the flexible bag 120 and the holder 110 jointly enclose a receiving space for receiving the laundry 020. The fixed seat 110 is provided with a suction port 111 for communicating the inside and the outside of the accommodating space, the negative pressure assembly 200 is communicated with the suction port 111, and the negative pressure assembly 200 is used for deforming and shrinking the flexible bag 120 by suction, so as to extrude the water in the washings 020 out of the washing chamber 100 through the suction port 111.

In the embodiment of fig. 1 and 2, in the normal use condition, the fixed seat 110 is located below the flexible bag 120, i.e. the suction opening 111 is located at the bottom of the washing chamber 100, and the mouth of the flexible bag 120 is connected to the fixed seat 110 downward. Since the water in the washing chamber 100 is more likely to accumulate at the bottom of the washing chamber 100 under the action of gravity, the suction port 111 is disposed at a lower position of the whole washing chamber 100, which is more beneficial for the negative pressure assembly 200 to pump water away. Of course, in alternative embodiments, the fixing base 110 may be disposed on the upper side, and the flexible bag 120 may be disposed on the lower side, so that the flexible bag 120 is suspended below the fixing base 110; alternatively, the flexible pouch 120 and the holder 110 are arranged in a horizontal direction. In the present embodiment, the first valve is disposed at the suction port 111 and is used for controlling the opening or closing of the suction port 111, and when the first valve is closed, the water in the washing chamber 100 can be prevented from being unnecessarily drained when the washing chamber 100 performs the non-dehydration operation. For example, when the washings 020 are washed in the washing chamber 100, the water is required to be retained, and the first valve is closed to avoid water loss. Of course, in some embodiments, the first valve may be omitted in the case where the washing chamber 100 is used only for dewatering.

Optionally, at least one opening is disposed on the flexible bag 120 or the fixing base 110 to serve as a laundry inlet and outlet, the laundry inlet and outlet is disposed on the flexible bag 120 or the fixing base 110 and communicated with the inside and the outside of the washing chamber 100, and a sealing device is disposed at the laundry inlet and outlet to seal the inside and the outside of the washing chamber.

In this embodiment, the edge of the mouth of the flexible bag 120 includes a fixed edge and a movable edge, the fixed edge is connected with the fixed seat 110 in a sealing manner, the movable edge is detachably connected with the fixed seat 110, and the movable edge is connected with the fixed seat 110 and then sealed. In this embodiment, the connection mode between the fixing edge of the bag opening and the fixing base 110 may be bonding, crimping or fastening, and the user does not need to separate the fixing edge from the fixing base 110 in the daily use process, thereby ensuring the connection stability and sealing performance between the flexible bag 120 and the fixing base 110. The movable edge of the bag opening is detachably connected with the fixed seat 110, so that a user can put the washings 020 into the flexible bag 120 or take the washings out of the flexible bag 120 by separating the movable edge of the bag opening from the fixed seat 110; in some embodiments, a single opening or multiple openings may be provided directly in the flexible bag 120 and may be configured with a sealing device, such as a sealing zipper, a sealing lip, etc.; or no other opening is arranged on the flexible bag 120, the bag mouth is completely sealed and connected on the fixed seat 110, and an opening is arranged on the fixed seat 110 and is provided with a matched sealing device, such as a sealing door and the like. In this embodiment, the movable edge of the bag opening may be detachably connected to the fixed base 110 by a zipper or a zipper. It should be understood that in alternative embodiments, the edges of the bag opening may be all movable edges, so that the flexible bag 120 can be completely detached from the holder 110; the edges of the bag opening can also be all fixed edges, and the fixed seat 110 or other positions of the flexible bag 120 are provided with placing openings for placing or taking out the washings 020.

Optionally, at least a portion of the flexible bag 120 is made of a transparent material, so that the washings 020 in the flexible bag 120 can be observed conveniently. The flexible bag 120 may be made of a plastic film having a certain strength, or rubber or silicone having elasticity. The flexible bag 120 has a convex structure with a certain curvature or the like, so that the flexible bag is not too far away from the fixed seat 110 in a natural state, and is convenient for vacuum pumping and extrusion.

As can be seen from the comparison between fig. 1 and fig. 2, when dewatering, the whole flexible bag 120 will contract under negative pressure to press the laundry 020, and moisture and air will be drawn out from the suction opening 111, which is different from the conventional centrifugal dewatering, and the dewatering has the advantages of low vibration and noise, less damage to the laundry, no need of an outer tub, and no bacteria growth between the conventional inner and outer tubs.

The fixing base 110 can effectively support the laundry 020 and also define the overall position of the washing chamber 100. The suction port 111 is arranged on the fixed seat 110, so that the position of the suction port 111 can be ensured to be fixed, and the stability of the connection between the washing bin 100 and the negative pressure assembly 200 is also ensured. In alternative embodiments, the suction opening 111 may be provided not on the holder 110 but on the flexible bag 120.

As shown in fig. 1 and 2, in the present embodiment, the fixing base 110 is located at one side of the flexible bag 120, the bag-type vacuum press dehydration apparatus 010 further includes a supporting member 116, the supporting member 116 is fixed with respect to the fixing base 110, and a side of the flexible bag 120 away from the fixing base 110 is connected to the supporting member 116. Specifically, the fixing base 110 of the present embodiment is located at the lower side of the flexible bag 120, and the supporting member 116 is connected to the upper side of the flexible bag 120 and is fixed relative to the fixing base 110. In one embodiment, the supporting member 116 can be fixedly connected to the fixing base 110 by a connecting member (not shown). In some embodiments, the flexible bag 120 and the fixing base 110 may be in other relative positions, such as the flexible bag 120 is below, beside, or the like the fixing base 110, and the form maintenance of the flexible bag 120 is achieved by the supporting member 116.

In this embodiment, the fixing base 110 is further provided with a water supply port 112, and the water supply port 112 communicates the inside and the outside of the washing tub 100. The water supply port 112 may be connected to an external water source through a pipe to supply water to the washing tub 100, so as to perform washing and rinsing functions. In alternative embodiments, the water supply port 112 may also be provided on the flexible bag 120. A second valve is provided at the water supply port 112 for controlling the opening or closing of the water supply port 112. When the dehydration is performed, the second valve should be closed so as to create a negative pressure environment inside the washing tub 100.

Optionally, the bag-type vacuum extrusion dewatering device 010 further includes a heating assembly (not shown), and the heating assembly is disposed on the fixing base 110. The heating assembly is used to provide heat into the washing compartment 100 to increase the temperature in the washing compartment 100. It can be understood that at higher temperature, the saturated vapor pressure is higher, and the moisture in the washings 020 is converted into gas more, so that the water is more favorably pumped out, and the residual water in the washings 020 which is difficult to discharge by extrusion is reduced. Therefore, the dewatering effect can be improved by adding the heating assembly. The heating assembly may be a heating coil, a ceramic heating plate, or the like. The heating element may be attached to the outer side of the fixing base 110, may be disposed on the inner side of the fixing base 110, or may be embedded in the fixing base 110.

In this embodiment, the bag-type vacuum press dehydration apparatus 010 further includes an auxiliary cleaning apparatus 113, and the auxiliary cleaning apparatus 113 is disposed at a side of the fixed base 110 facing the accommodating space, and is used for assisting the cleaning of the laundry 020. In this embodiment, the auxiliary cleaning device 113 may be a pulsator, and when the laundry 020 is soaked in water, the laundry 020 is cleaned by the rotation of the pulsator. Of course, in alternative embodiments, the auxiliary cleaning device 113 may also include a device for performing other functions, such as a filtering device, for filtering impurities.

As shown in fig. 1 and 2, in the present embodiment, the negative pressure assembly 200 includes a gas-liquid pipe 220, a water tank 210, and an air pump 230, the water tank 210 has an inlet and an outlet, one end of the gas-liquid pipe 220 is connected to the suction port 111, the other end is connected to the inlet of the water tank 210, the air pump 230 is connected to the outlet of the water tank 210, and the gas-liquid pipe 220 is provided with a first valve. In the present embodiment, gas-liquid line 220 is connected to the bottom of water tank 210, i.e., the inlet of water tank 210 is disposed at the bottom; in alternative embodiments, gas-liquid line 220 may also be connected to the top of tank 210.

It should be understood that the air pump 230 is connected to the air outlet of the water tank 210, which means that the air pump 230 can be at least in a certain state communicated with the air outlet of the water tank 210, so that the air pump 230 can generate negative pressure in the space inside the water tank 210 when sucking; the air pump 230 may be directly connected to the air outlet of the water tank 210 or may be indirectly connected to the air outlet of the water tank 210 through a pipe. Specifically, in this embodiment, the negative pressure assembly 200 further includes an air tube 250 and a multi-way valve 240, one end of the air tube 250 is connected to the air outlet of the water tank 210, the other end of the air tube 250 is connected to the multi-way valve 240, an air suction end of the air pump 230 is connected to the multi-way valve 240, and the multi-way valve 240 selectively enables the air suction end of the air pump 230 to communicate with the air tube 250 or communicate with the atmosphere by switching. When dehydration is required, the air suction end of the air pump 230 is communicated with the air pipe 250, so as to provide negative pressure for the water tank 210 and even the washing bin 100; when the dehydration is to be suspended, the air pump 230 is not required to be turned off, and the air suction end of the air pump 230 is only communicated with the atmosphere.

Of course, there may be other connections between the multi-way valve 240 and the air pump 230. For example, when the inlet of the water tank 210 is disposed at the top of the water tank 210, the exhaust end of the air pump 230 may also be connected to the multi-way valve 240, and when the dehydration is completed, the exhaust end of the air pump 230 is communicated with the air pipe 250 and the air inlet end is communicated with the atmosphere by switching the multi-way valve 240, so that air may be blown into the washing compartment 100, and the washing compartment 100 may be rapidly restored to the state before the dehydration.

Optionally, the water tank 210 may further include a water outlet, a drain valve is disposed at the water outlet, and the height of the water outlet is lower than that of the air outlet. When gas or liquid enters the tank 210 from the inlet of the tank 210 by suction, the liquid is deposited on the bottom of the tank 210, and the gas is discharged out of the tank 210 through the outlet and is delivered toward the air pump 230. It is apparent that in the case where the air pump 230 does not have the gas-liquid separating function, the height of the air outlet is required to be higher than the liquid level in the water tank 210 in order to prevent water from being sucked from the air outlet and transferred to the air pump 230. Thus, in the present embodiment, the gas-liquid mixture flow delivered from the washing tub 100 to the water tank 210 is separated at the water tank 210, water remains in the water tank 210, and gas is discharged out of the water tank 210 by the suction force. When the water level in the water tank 210 reaches a certain level, water may be discharged from the water tank 210 by opening the drain valve.

Optionally, a water level detector (not shown in the figure) for detecting the water level in the water tank 210 may be disposed on the water tank 210, so as to monitor the water level in real time, and when the water level is too high, the drain valve is opened to drain water, thereby preventing the water from flowing into the air pipe 250 and the air pump 230 due to the too high water level. In addition, the water tank 210 may further be provided with an air pressure detector to feed back air pressure information in real time, so that if an abnormality occurs during the dehydration process, the abnormality can be checked in time.

Fig. 3 and 4 are schematic views of a bag-type vacuum press dehydration apparatus 010 before and during dehydration in accordance with another embodiment of the present application. The bag-type vacuum press dehydration apparatus 010 in the embodiment shown in fig. 3 and 4 is different from the bag-type vacuum press dehydration apparatus 010 in the embodiment of fig. 1 and 2 in the shape of the holder 110. In the embodiment shown in fig. 3 and 4, the fixing base 110 includes a first fixing portion 114 and a second fixing portion 115, the bag mouth edge of the flexible bag 120 is connected to the first fixing portion 114 and the second fixing portion 115, the first fixing portion 114 has a first inner surface facing the accommodating space, the second fixing portion 115 has a second inner surface facing the accommodating space, and the first inner surface and the second inner surface are disposed at an included angle, so that the first inner surface and the second inner surface are respectively located at two different sides of the flexible bag 120. Specifically, in the present embodiment, the first inner surface constitutes a bottom wall of the accommodating space, and the second inner surface constitutes one side wall of the accommodating space, in other words, the first fixing portion 114 is located at the bottom side of the flexible bag 120, and the second fixing portion 115 is located at the side of the flexible bag 120 in the horizontal direction. Since the holder 110 is capable of supporting the flexible bag well, the support member 116 in the embodiment of fig. 1 and 2 may be omitted in this case. Further, the first inner surface is perpendicular to the second inner surface.

Through setting up fixing base 110 to contain the first fixed part 114 and the second fixed part 115 that are the contained angle, can have diversified support to flexible bag 120, can guarantee the stability of whole washing chamber 100 better. Meanwhile, providing the L-shaped fixing base 110 as shown in fig. 3 and 4 allows more space for arranging the suction port 111 and the water supply port 112, for example, the water supply port 112 is provided on the second fixing portion 115, the suction port 111 is provided on the first fixing portion 114, and the auxiliary cleaning device 113 may be provided at a connecting position of the first fixing portion 114 and the second fixing portion 115. In alternative embodiments, two or more suction ports 111 may be provided on the fixing base 110 to perform suction from different positions.

When the bag-type vacuum extrusion dewatering device 010 provided by the embodiment of the application is used for dewatering, the process is as follows:

the washings 020 to be dewatered are put in the washing chamber 100, the water tank 210 is vacuumized by the air pump 230, and then the first valve at the suction port 111 is opened, so that the water in the washing chamber 100 flows into the water tank 210 through the gas-liquid pipe 220. During this process, if the remaining volume of the water tank 210 is sufficient, suction is maintained. When the flowing water around the washings 020 is sent into the water tank 210 through the gas-liquid pipe 220, at this time, because the large negative pressure still exists in the washing chamber 100, the flexible bag 120 further contracts and presses the washings 020 to extrude the moisture in the washings 020, so that the water in the washings 020 can be pumped away. If the water level meter or other detection means detects that the water tank 210 is full of water, it is necessary to suspend the suction of the washing tub 100, open the drain valve of the water tank 210, and discharge the contaminated water stored in the water tank 210. And closing the drain valve after the sewage is discharged, and repeating the suction and dehydration steps until the extrusion and dehydration are finished. After the water tank 210 sucks most of the flowing water in the washing chamber 100, the heating assembly is started to heat the washing chamber 100, so that the water in the washings 020 is vaporized, and then the water vapor is pumped out through the negative pressure, thereby further improving the drying effect.

The bag-type vacuum extrusion dewatering device 010 that this application embodiment provided dewaters the power source for air pump 230, compares in traditional centrifugal dehydration mode, does not have great rocking and noise, consequently need not to increase extra counter weight or damping device for overall structure is simple compact, is applicable to the equipment use of miniaturization, lightweight. Corresponding installation parts and installation space can be saved compared with the method of applying pressure on the outer side of the washing chamber 100 in a hydraulic, electric or pneumatic mode and the like. The water tank 210 of the negative pressure assembly 200 in this embodiment can have a high vacuum degree through suction, and after the water tank is communicated with the washing chamber 100, the flexible bag 120 can quickly squeeze the washings 020, so that the sewage in the washings 020 can be quickly discharged. Compared with the gravity drainage and centrifugal dehydration or extrusion filtration dehydration and other modes in the prior art, the dehydration speed is higher and the efficiency is higher.
