Description

Technical Field

[0001] The utility model relates to the field of washing machines, in particular to a wringing-type clothing care machine. Background Art

[0002] An underwear washing machine is a type of washing machine with a compact structure, used for cleaning small, close-fitting garments such as underwear and panties. Currently, mainstream underwear washing machines still use an additional water filter basket for dehydration, which is fixed to the impeller. The cleaned clothes are then placed in the filter basket, and the impeller drives the filter basket to rotate at high speed to dry the clothes. This method has a drawback, namely, it requires a motor to drive the impeller to rotate at high speed. However, underwear washing machines are relatively small and lightweight, so when the inertia generated by the motor driving the impeller to rotate at high speed is transferred to the underwear washing machine, it causes the underwear washing machine to shake significantly. Therefore, underwear washing machines often require a fixing device to secure the underwear washing machine, and the motor performance requirements are relatively high. Utility Model Content

[0003] In order to solve the above problems, the purpose of the present invention is to provide a clothing care machine that dehydrates clothes by wringing, thereby causing less shaking during operation and having lower requirements on motor performance.

[0004] The technical solution adopted by the utility model to solve the problem is: a wringing type clothing care machine, comprising:

[0005] A base, wherein a soft rubber cylinder is mounted on the base, wherein a closed washing chamber is formed in the soft rubber cylinder, wherein a pulsator is pivotally connected to the bottom of the washing chamber, wherein the surface of the pulsator is provided with auxiliary edges, wherein a driving motor connected to the pulsator is provided in the base, and an opening and closing structure for movably opening and closing the washing chamber is provided on the soft rubber cylinder;

[0006] A vacuum pump, the vacuum pump being connected to the washing chamber via a vacuum tube, and the vacuum pump being used to evacuate the washing chamber so that the soft rubber cylinder is deformed under the action of external air pressure;

[0007] A drainage channel, the end of which is connected to the washing chamber, and a first opening and closing valve body is provided on the drainage channel;

[0008] A water inlet channel is connected to the washing chamber and is provided with a second opening and closing valve body.

[0009] As a further improvement of the above technical solution, the soft rubber tube includes a left sheet and a right sheet, and the opening and closing structure is a sealing zipper connecting the left sheet and the right sheet respectively.

[0010] As a further improvement of the above technical solution, the left sheet and the right sheet are arranged on the top of the soft rubber cylinder.

[0011] As a further improvement of the above technical solution, a sealing sheet is further provided on the outer surface and / or inner surface of the left sheet body, and the sealing sheet covers the outside of the sealing zipper and adheres to the surface of the right sheet body.

[0012] As a further improvement of the above technical solution, a transfer water tank located at the front end of the first opening and closing valve body is provided in the drainage channel.

[0013] As a further improvement of the above technical solution, the first opening and closing valve body and the second opening and closing valve body are both electric ball valves.

[0014] As a further improvement of the above technical solution, the auxiliary edges are a number of ribs starting from the center of the impeller and spreading toward the edge of the impeller.

[0015] As a further improvement of the above technical solution, the top of the impeller is spherical.

[0016] As a further improvement of the above technical solution, the outer wall of the soft rubber cylinder is recessed toward the inside of the washing cavity to form a plurality of vertical grooves and the inner wall of the washing cavity is formed with a plurality of reinforcing ridges.

[0017] As a further improvement of the above technical solution, the vacuum tube is connected to the top of the soft rubber cylinder.

[0018] The beneficial effects of the utility model are as follows: when in use, the washing chamber is first opened through the opening and closing structure, clothes are loaded therein and the washing chamber is closed, water is injected into the washing chamber through the water inlet channel, the driving motor drives the pulsator to rotate at a specified frequency to wash the clothes, and when washing is completed, the second opening and closing valve body is opened to discharge the water in the washing chamber first, and then the first opening and closing valve body and the second opening and closing valve body are ensured to be in a closed state, so that a sealed space is formed in the washing chamber, and then the vacuum pump evacuates the washing chamber. Since the outer wall of the washing chamber is a soft rubber cylinder, when the washing chamber is evacuated, the outer wall of the soft rubber cylinder will be deformed and compressed inwardly under the action of external air pressure, thereby releasing the clothes in the washing chamber. The clothes are pressed tightly against the surface of the impeller, and the auxiliary corners on the surface of the impeller assist the impeller in grasping the bottom of the clothes. Then the driving motor drives the impeller to rotate back and forth at a specified frequency. The outer end of the clothes is fixed by the deformation and compression of the inner surface of the soft rubber cylinder, and the lower end of the clothes is fixed by the impeller through the auxiliary corners, so that the clothes can be twisted and deformed during the rotation of the impeller, and then the moisture in the clothes is wrung out. The wrung-out moisture is first retained in the drainage channel. When the specified wringing time is completed, or the wrung-out moisture reaches a certain amount, the first opening and closing valve body is opened again to discharge the water. At this time, air enters the washing chamber, causing the soft rubber cylinder to recover under the action of its own elastic deformation. Through this solution, the moisture in the clothes is squeezed out by twisting, so the speed requirement of the driving motor is relatively low. Therefore, it is not easy to cause large vibrations during the washing process, which is convenient for installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Reference Figures 1 to 2 , a wringing-type clothing care machine, comprising:

[0026] A base 10 is mounted on a soft rubber cylinder 30. A closed washing chamber is formed in the soft rubber cylinder 30. A pulsator 20 is pivotally connected to the bottom of the washing chamber. The surface of the pulsator 20 is provided with auxiliary corners. A drive motor connected to the pulsator 20 is provided in the base 10. An opening and closing structure for movably opening and closing the washing chamber is provided on the soft rubber cylinder 30.

[0027] A vacuum pump, which is connected to the washing chamber through a vacuum tube and is used to evacuate the washing chamber so that the soft rubber cylinder 30 is deformed under the action of external air pressure;

[0028] A drainage channel 11, the end of which is connected to the washing chamber, and a first opening and closing valve body is provided on the drainage channel 11;

[0029] The water inlet channel 12 is connected to the washing chamber, and a second opening and closing valve body is provided on the water inlet channel 12.

[0030] When in use, first open the washing chamber through the opening and closing structure, put the clothes into it and close the washing chamber, inject water into the washing chamber through the water inlet channel 12, and drive the pulsator 20 to rotate at a specified frequency to wash the clothes. When washing is completed, open the second opening and closing valve body to drain the water in the washing chamber first, and then ensure that the first opening and closing valve body and the second opening and closing valve body are in a closed state to form a sealed space in the washing chamber, and then vacuum the washing chamber with a vacuum pump. Since the outer wall of the washing chamber is a soft rubber cylinder 30, when the washing chamber is vacuumed, the outer wall of the soft rubber cylinder 30 will be deformed and compressed inwardly under the action of external air pressure, thereby pressing the clothes in the washing chamber against the surface of the pulsator 20. The auxiliary corners on the surface of the pulsator 20 assist the pulsator 20 in gripping the bottom of the clothes, and then the driving motor drives the pulsator 20 to rotate back and forth at a specified frequency. The outer end of the clothes is fixed by the deformation and compression of the inner surface of the soft rubber cylinder 30, and the lower end of the clothes is fixed by the pulsator 20 through the auxiliary corners, so that the clothes can be twisted and deformed during the rotation of the pulsator 20, and the moisture in the clothes is wrung out. The wrung out moisture is first retained in the drainage channel 11. When the specified wringing time is completed, or the wrung out moisture reaches a certain amount, the first opening and closing valve body is opened again to discharge the water. At this time, air enters the washing chamber, causing the soft rubber cylinder 30 to recover under the action of its own elastic deformation. Through this solution, the moisture in the clothes is squeezed out by twisting, so the speed requirement of the driving motor is relatively low. Therefore, it is not easy to cause large vibrations during the washing process, which is convenient for installation.

[0031] In this embodiment, to optimize the opening and closing structure, the soft rubber tube 30 preferably includes a left sheet 301 and a right sheet 302, and the opening and closing structure is a sealing zipper 40 connecting the left and right sheets 301, 302. To further ensure sealing, the outer and / or inner surfaces of the left sheet 301 are preferably further provided with a sealing sheet, which covers the outside of the sealing zipper 40 and adheres to the surface of the right sheet 302, so that the sealing sheet can further close the gap between the sealing zippers 40 from both sides.

[0032] For further optimization, since the space in the drainage pipe is limited, in order to store as much dehydration water as possible during the dehydration process, it is preferred that a transfer water tank located at the front end of the first opening and closing valve body is provided in the drainage channel 11.

[0033] In this solution, preferably, the first opening and closing valve body and the second opening and closing valve body are both electric ball valves. In other embodiments, the first opening and closing valve body and the second opening and closing valve body can also be other valve bodies such as solenoid valves.

[0034] In this embodiment, the auxiliary corners are designed to help the pulsator 20 better grip clothing. Preferably, the auxiliary corners are ribs 21 extending from the center of the pulsator 20 and extending toward the edge of the pulsator 20. In other embodiments, the auxiliary corners can also be raised dots arranged in an array on the surface of the pulsator 20. To maximize the contact surface between the pulsator 20 and clothing while minimizing damage, the top of the pulsator 20 is preferably spherical.

[0035] For further optimization, it is preferred that the outer wall of the soft rubber tube 30 is recessed toward the inside of the washing chamber to form a plurality of vertical grooves 31 and that the inner wall of the washing chamber is formed with a plurality of reinforcing ridges, so that the soft rubber tube 30 can more easily remain upright through the grooves 31 and the reinforcing ridges when it is not squeezed and deformed by atmospheric pressure.

[0036] In other embodiments, the opening and closing structure may include: the soft rubber cylinder 30 includes an upper half and a lower half, a first annular fixing bracket is provided at the top of the lower half, and a second annular fixing bracket is provided at the bottom of the upper half, the first fixing bracket is provided with an internal thread, and the second fixing bracket is provided with an external thread that is screwed to the internal thread, so that the upper and lower half cylinders are combined together through the screwing action of the internal and external threads to form a closed washing chamber. However, in this method, when the soft rubber cylinder 30 is squeezed and deformed by air pressure, the first and second fixing brackets do not deform.

[0037] For further optimization, it is preferred that the vacuum tube is connected to the top of the soft rubber cylinder 30, so that when vacuuming, no excessive water is sucked into the vacuum pump. In other embodiments, the vacuum tube can also be connected to the bottom of the washing chamber. In this way, the vacuuming process will inevitably extract some water. In this structure, either a dual-purpose vacuum pump for gas and liquid is used, or a transfer cavity is set in the base. The vacuum tube is divided into a front pipe section connected to the vacuum pump and a rear pipe section connected to the washing chamber. The end of the front pipe section is connected to the top of the transfer cavity, and the front end of the rear pipe section is connected to the bottom of the transfer cavity. At the same time, a drain port connected to the drain channel 12 is provided at the bottom of the transfer cavity. At the same time, a baffle is provided in the transfer cavity below the port of the front pipe section. Therefore, during the vacuuming process, the air and water in the washing chamber are simultaneously drawn into the transfer cavity, the water falls into the bottom of the transfer cavity, and the air is drawn out from the top of the transfer cavity by the front pipe section. At the same time, the baffle prevents the water from being swung into the front pipe section when it oscillates in the transfer cavity.

[0038] The above are only preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or directly or indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
