Description

Technical Field

[0001] The invention relates to the field of washing machines, in particular to an underwear washing machine. Background Art

[0002] An underwear washing machine is a type of washing machine used to clean small underwear and other close-fitting garments. It has a compact structure and a small capacity. Generally, an underwear washing machine can wash about three to five pieces of underwear, which just meets the needs of one person. At present, the mainstream underwear washing machines use an additional water filter basket to fix the water filter basket on the impeller during dehydration, and the cleaned clothes are loaded into the water filter basket. The impeller drives the water filter basket to rotate at high speed to spin dry the clothes. This method has a defect, that is, it requires a motor to drive the impeller to rotate at high speed, but the structure of the underwear washing machine is relatively small and the weight is relatively light. Therefore, when the inertia generated by the motor driving the impeller to rotate at high speed is transferred to the underwear washing machine, it will cause the underwear washing machine to shake greatly. Therefore, the underwear washing machine often needs to install multiple suction cups at the bottom for fixing. And due to this defect, the current underwear washing machines cannot be hung on the wall for use. Summary of the invention

[0003] In order to solve the above problems, an object of the present invention is to provide an underwear washing machine which does not generate large vibrations during operation and thus has greater stability.

[0029] Reference Figures 1 to 5 , a underwear washing machine, comprising

[0030] A washing machine body 10, wherein a mounting hole 11 is provided on the back of the washing machine body 10, a mounting seat 12 is provided on the washing machine body 10, a soft rubber cylinder 20 is installed on the mounting seat 12, the soft rubber cylinder 20 and the top surface of the mounting seat 12 enclose a washing chamber, the soft rubber cylinder 20 is provided with an opening and a sealing zipper 21 for opening and closing the opening, a pulsator 30 located at the bottom of the washing chamber is provided on the mounting seat 12, a plurality of grabbing protrusions 31 are provided on the surface of the pulsator 30, a driving motor 40 connected to the pulsator 30 is provided in the mounting seat 12, and a water level sensor 50 for detecting the water volume is provided on the washing machine body 10;

[0031] A vacuum pump 60, wherein the vacuum pump 60 is provided with a vacuum tube 61 connected to the washing chamber, and the vacuum pump 60 drives the soft rubber cylinder 20 to collapse and deform when evacuating the washing chamber;

[0032] A hot air pipe 71, the end of which is connected to the washing chamber, a first heater 71 and a hot air blower are provided in the hot air pipe 71, and an opening and closing valve 72 is provided at the rear end of the hot air pipe 71;

[0033] A water inlet pipe 801, the water inlet pipe 801 is connected to the washing chamber, a water inlet valve 81 is provided on the water inlet pipe 801, and a second heater is provided on the water inlet pipe 801;

[0034] A drain pipe 901 is provided with a water storage tank 100 in the middle of the drain pipe 901 , a front end of the drain pipe 901 is connected to the washing chamber, and a drain valve 91 is provided at the rear end of the drain pipe 901 .

[0035] When in use, the soft rubber cylinder 20 is first opened through the sealing zipper 21 to load the underwear into the washing chamber, and then the sealing zipper 21 is closed, the drain valve 91 is closed, and the water inlet valve 81 is opened. At the same time, the second heater works to introduce hot water into the washing chamber. After a certain amount of hot water is introduced, the water inlet valve 81 is closed, and the driving motor 40 drives the pulsator 30 to wash the clothes at a specified speed. After washing is completed, the drain valve 91 is opened to drain the water in the washing chamber, and then the drain valve 91 is closed, and the vacuum pump 60 evacuates the washing chamber, so that the soft rubber cylinder 20 collapses and deforms under the action of the external atmospheric pressure, and then the clothes are pressed to the surface of the pulsator 30. The pulsator 30 fixes the bottom of the clothes by the grabbing protrusion 31, and the upper part of the clothes is fixed by the collapsed and deformed soft rubber cylinder 20. Then the driving motor 40 drives the pulsator 30 to rotate slowly, thereby twisting the clothes, thereby wringing out the water in the clothes. At this time, the wrung out water accumulates in the water storage tank 100. After the wringing is completed, the vacuum pump 60 stops vacuuming and the drain valve 91 opens, so that the wrung water is discharged and the soft rubber cylinder 20 is restored under its own elasticity, and then the opening and closing valve 72 opens the hot air pipe 71, and the hot air blower and the first heater 71 work to blow hot air into the washing chamber for further drying. Through this solution, the dehydration method of the clothes is changed from high-speed spin drying to low-speed wringing, so that the underwear washing machine disclosed in this solution will not produce large vibrations when working, so that the stability is stronger, and there is no need to set a suction cup for fixing, and it can be hung on the wall through the installation hanging hole 11 set on the back of the washing machine body 10, so as to make better use of space.

[0036] Further optimization, since underwear washing machines can generally only wash three to five pieces of underwear, for families with a large population, queuing for laundry is time-consuming, so multiple underwear washing machines are generally purchased to form an array mode. However, each of the current underwear washing machines requires a faucet, which makes the external pipeline too complicated and takes up space. For this reason, it is preferred that the washing machine body 10 is provided with a water inlet channel 80, and both ends of the water inlet channel 80 extend to the outside of the washing machine body 10 to form a water inlet and a water inlet outlet, and the water inlet pipe 801 is connected to the middle of the water inlet channel 80; the washing machine body 10 is provided with a drainage channel 90, and both ends of the drainage channel 90 extend to the outside of the washing machine body 10 to form a drainage inlet and a drainage outlet, and the drainage pipe 901 is connected to the drainage channel 90, and plugs 89 are movably installed on the water inlet and drainage inlet. Therefore, when multiple underwear washing machines are needed to form an array, it is only necessary to connect the water inlet and outlet of two adjacent underwear washing machines, connect the drainage inlet and outlet, and seal the drainage inlet of the first underwear washing machine and the water inlet outlet of the last underwear washing machine with the plug 89, so as to complete the pipeline construction, reduce the demand for external accessories, and put the water inlet and drainage of all underwear washing machines in parallel, so that only one faucet and one sewage outlet are needed.

[0037] For further optimization, the opening is preferably arranged at the top of the soft rubber cylinder 20, so as to facilitate taking and placing clothes.

[0038] In order to facilitate the removal of the soft rubber cylinder 20 for cleaning, it is preferred that the outer periphery of the mounting seat 12 is provided with an external thread 221, a table body is provided in the middle of the top surface of the mounting seat 12 and the outer periphery of the table body forms an annular table surface, the impeller 30 is arranged on the table body, the bottom of the soft rubber cylinder 20 is sleeved on the outer periphery of the table body and the bottom surface of the soft rubber cylinder 20 abuts against the annular table surface, the outer periphery of the soft rubber cylinder 20 is provided with an outer flange 201, and a fixing sleeve 22 is screwed on the mounting table, the fixing sleeve 22 includes a pressure ring at the top and a locking ring located at the outer periphery of the pressure ring, the inner wall of the locking ring is provided with an internal thread matching the external thread 221, and the pressure ring is pressed onto the top plate of the outer flange 201.

[0039] In this solution, it is preferred that an independent mounting plate is provided on the back of the washing machine body 10, and the mounting hanging hole 11 is provided on the mounting plate and runs through the front and back of the mounting plate, so that the underwear washing machine can be hung or directly nailed to the wall with a larger nail. If no independent mounting plate is provided on the back of the washing machine body 10, the underwear washing machine is mainly hung, so the specific selection method is set according to the target customer group.

[0040] For further optimization, in order to simplify the structure, it is preferred that the hot air pipe 71, the vacuum pipe 61 and the water inlet pipe 801 are all connected to the water storage tank 100, so as to be connected to the washing chamber through the water storage tank 100. Of course, each pipe can also be arranged separately as needed. In order to avoid the phenomenon of water absorption caused by the vacuum pump 60, it is preferred that the vacuum pipe 61 is connected to the top of the water storage tank 100, so that it only draws air, and cannot draw the water in the water storage tank 100 upward out of thin air.

[0041] For further optimization, it is preferred that the surface of the impeller 30 is spherical, and the grabbing protrusions 31 are a plurality of ridges starting from the center of the impeller 30 and extending toward the periphery of the impeller 30. In other embodiments, the grabbing protrusions 31 may also be convex points arranged in an array. The purpose of the grabbing protrusions 31 is to be able to form a fixation with the clothes, thereby driving the clothes to twist, and it is not necessary to maintain the grip throughout the whole process. Slippage may occur after the clothes are grabbed with more than a certain force.

[0042] In this embodiment, the water inlet valve 81 and the drain valve 91 are preferably electric ball valves, and the opening and closing valve 72 is preferably a solenoid valve. In other embodiments, the opening and closing valve 72 may also be a damper for opening and closing the hot air pipe 71 and a swing motor connected to the damper and driving the damper to swing. In other embodiments, the water inlet valve 81, the drain valve 91, and the opening and closing valve 72 may also be other valve bodies with on-off functions, such as electric butterfly valves, electric plug valves, etc.

[0043] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or directly or indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
