Description

Technical Field

[0002] At present, most drum washing machines have a structure with holes in the inner drum, and the inner drum and the outer drum are connected, which has the following problems:

[0003] 1. The water between the outer drum and the inner drum does not participate in washing and becomes wasted water;

[0004] 2. Over time, serious dirt and mildew will form on the wall between the inner and outer drums, causing secondary pollution to the clothes. The dirt in the outer drum will enter the inner drum, causing secondary pollution to the clothes.

[0005] In the prior art, the research and development innovation of non-porous inner drum washing machines is mainly concentrated on pulsator washing machines, and there is little research and development on the non-porous inner drum structure of drum washing machines. The patent application with publication number CN107447425A is a drum washing machine and a cleaning method thereof disclosed by Qingdao Haier Drum Washing Machine Co., Ltd., which is provided with an annular isolation channel between the outer drum and the inner drum. The isolation channel can be arranged on the outer drum to rotate relative to the inner drum, or can be arranged on the inner drum to rotate relative to the outer drum. The isolation channel is connected to the perforated area of ​​the inner drum, so that the space between the outer drum and the inner drum is completely isolated from the inside of the inner drum, and then no sewage cross-flow is formed between the inner drum and the outer drum, and no dirt is attached and accumulated in the area between the outer drum and the inner drum.

[0006] However, in actual application of the technical solution of the patent application, when the isolation channel rotates relatively between the inner and outer drums, the sealing of the connection between the isolation channel and the inner and outer drums is extremely poor, and washing water still exists between the inner and outer drums; moreover, when the washing drum rotates at high speed, the washing drum often shakes and rotates. During the shaking process, the connection between the isolation channel and the inner and outer drums will deform or displace, affecting the isolation effect of the isolation channel, making it impossible to isolate the washing water between the inner and outer drums, and the effect of avoiding secondary pollution is poor.

[0007] In addition, the existing hole-free inner drum washing machines basically do not involve the drying function.

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0045] like Figures 1 to 11 As shown, the utility model discloses a no-cleaning drum washing machine with a drying function, comprising:

[0046] outer cylinder 1;

[0047] A non-porous washing cylinder 2, on which a liquid flow hole and a gas flow hole are arranged, wherein the liquid flow hole is used to connect the non-porous washing cylinder 2 with a water flow channel, and the gas flow hole is used to connect the non-porous washing cylinder 2 with an exhaust device, and the remaining positions are non-porous, and a drainage switch 4 for adjusting the on-off of the water flow channel is arranged on the water flow channel;

[0048] An exhaust device, used to pass the gas in the non-porous washing cylinder 2 to between the non-porous washing cylinder 2 and the outer cylinder 1 through the gas flow hole, and the setting position of the gas flow hole is higher than the washing liquid level;

[0049] The air duct assembly is used to condense the gas exhausted by the exhaust device through the condensing device, and the condensed gas is heated by the air duct heating system 11 and then passed into the non-porous washing cylinder 2.

[0050] The non-cleaning drum washing machine with drying function disclosed in the present application is provided with gas circulation holes for gas circulation on the non-porous washing drum 2 of the drum washing machine. Under the action of the exhaust device, the gas in the non-porous washing drum 2 can be passed to between the non-porous washing drum 2 and the outer drum 1, and the washing water is prevented from entering the exhaust device and the air duct assembly through the gas circulation holes. The exhaust device condenses the gas in the non-porous washing drum 2 through the condensation device between the non-porous washing drum 2 and the outer drum 1, and heats it with the air duct heating system 11, and then passes it into the non-porous washing drum 2 again in combination with the air duct pipe section, so as to realize the circulation heating of the gas inside the non-porous washing drum 2, thereby ensuring that the non-porous washing drum 2 realizes the drying function after washing is completed. In the example of the present application, the structural form of the water flow channel and the drainage switch of the non-porous washing drum 2 have been recorded in the public documents of the applicant's previous application for a non-porous inner drum drum washing machine, and will not be repeated here.

[0051] The no-clean drum washing machine with drying function disclosed in the present application realizes the drying function after washing by arranging gas circulation holes on the non-porous washing drum 2 and combining the exhaust device and the air duct assembly between the non-porous washing drum 2 and the outer drum 1, and circulates and heats the gas in the washing drum. On the basis of solving the problem that dirt is easily accumulated between the inner drum and the outer drum of the traditional drum washing machine, it realizes the demand of modern consumers for multifunctional washing machines and improves the overall performance and user experience of the washing machine.

[0052] As a preferred example of the present application, the exhaust device is arranged at the center position of the rear end of the hole-free washing drum 2, and an outer drum exhaust port 8 is arranged on the outer drum 1, and the outer drum exhaust port 8 is used to connect the exhaust device with the air duct component.

[0053] This arrangement sets the exhaust device at the center position of the rear end of the holeless washing drum 2. Correspondingly, the gas flow hole of the holeless washing drum 2 is also correspondingly set at the center position of its rear end. On the one hand, it reduces the flow of washing water to the exhaust device through the gas flow hole during the washing or dehydration process. Under static conditions, the setting position of the gas flow hole is higher than the washing liquid level. Under washing conditions or dehydration conditions, the centrifugal force generated by the rotation of the holeless washing drum 2 will move the washing water in its centrifugal direction, and will also move away from the gas flow hole near the center position of the rear end of the holeless washing drum 2. On the other hand, by connecting it with the outer drum exhaust port 8 set on the outer drum 1, the gas inside the holeless washing drum 2 can still reliably flow to the air duct component outside the outer drum 1 through the gas flow hole and the exhaust device when the holeless washing drum 2 is in a rotating state.

[0054] As a preferred example of the present application, the exhaust device includes a filter device 7, and the filter device 7 is used to filter the gas entering the air duct assembly. Specifically, the filter device 7 includes a filter seat 71, a first filter screen 72, and a filter cover 73. The filter cover 73 presses the first filter screen 72 into the filter seat 71, and the filter cover 73 is detachably connected to the filter seat 71. As a preferred example of the present utility model, the filter seat 71 is fixedly installed at the center position of the non-porous washing cylinder 2, and a first exhaust hole is provided on the filter seat 71. The first exhaust hole on the filter seat 71 is corresponding to the gas flow hole at the rear end of the non-porous washing cylinder 2. The first filter screen 72 is a filter cloth welded in a support ring to form a chamber structure with an opening on one side and a filter cloth on the other side. A third exhaust hole is also provided on the filter cover 73.

[0055] This arrangement allows the first filter 72 to be arranged in the filter cover 73, so that it can be easily taken in and out, and the hair scraps can be cleaned, so as to ensure that the exhaust gas is relatively clean during the drying process, thereby improving the safety and efficiency of the drying operation of the no-clean drum washing machine. Preferably, the filter cover 73 is connected to the filter seat 71 by means of threads or buckles, and is a quick-connect structure, which is easy to take in and out manually, and does not fall off when the machine rotates.

[0056] As a preferred example of the present application, the air duct assembly includes an air duct front end 9 and an air duct rear end 12, wherein the air duct front end 9 is connected to the outer drum exhaust port 8, and the air duct rear end 12 is connected to the inside of the non-porous washing drum 2 through the air inlet 15, and a condensing device, a fan 10 and an air duct heating system 11 are sequentially arranged on the air duct pipeline between the outer drum exhaust port 8 and the air inlet 15. The duct assembly is provided to realize condensation treatment and reheating of the discharged moisture, thereby ensuring the circulation, cleaning and temperature control of the gas inside the non-porous washing drum 2, and finally improving the drying effect of the non-cleaning drum washing machine.

[0057] As a preferred example of the present application, the air inlet 15 is arranged on the front door sealing ring 13 at the front end of the non-porous washing drum 2.

[0058] Alternatively, a door assembly is provided on the outside of the outer cylinder 1, and the door assembly includes an outer fixed door 1015 and an inner rotating door 1016. A water vapor passage 1012 is provided on the outer fixed door 1015. The door assembly is hingedly connected to the outer cylinder 1 through a hollow hinge assembly 1011. The water vapor passage 1012 is provided at the center of the outer fixed door 1015 toward the inner rotating door 1016 and is rotationally matched with the inner rotating door 1016 through a bearing 1014 and a water seal 1013. The water vapor passage 1012 passes through the center of the inner rotating door 1016 and is connected to the internal space of the non-porous washing cylinder 2. The periphery of the inner rotating door 1016 is sealed with the washing cylinder mouth of the non-porous washing cylinder 2 through a second sealing ring 1017. The inner rotating door 1016 and the second sealing ring 1017 can rotate integrally with the non-porous washing cylinder 2, and the rear end 12 of the air duct is connected to the hollow hinge assembly 1011.

[0059] The arrangement discloses two air intake structures of the air duct assembly, one is that the rear end 12 of the air duct directly enters the non-porous washing drum 2 through the air inlet 15 set on the front door sealing ring 13 relatively fixed at the front end of the non-porous washing drum 2, and the other is that by setting the door assembly to have an external fixed door 1015 hingedly fixed relative to the outer drum 1 and an internal rotating door 1016 that rotates integrally with the non-porous washing drum 2, combined with a hollow hinge assembly 1011, the dry air heated at the rear end 12 of the air duct passes through the hollow hinge assembly 1011 and the water vapor passage 1012 and enters the interior of the non-porous washing drum 2 from the center of the internal rotating door 1016, thereby realizing the circulation of the dry air.

[0060] Through the above design, the dry air at the rear end 12 of the air duct can enter the inside of the porous washing drum 2, thereby realizing the drying function, improving the drying effect, and ensuring that the dry air can flow into the porous washing drum 2 evenly and cleanly.

[0061] As a preferred example of the present application, the hollow hinge assembly 1011 includes a hinge 1023 and a hinge seat 1024, wherein the hinge seat 1024 is fixedly mounted on the outer drum 1, and the hinge 1023 is mounted on the door assembly, wherein the hinge 1023 is arranged in a three-way shape, wherein one end is connected to a rotatable air pipe 1026, and the other end is connected to a rotatable water pipe 1025, and the middle position thereof is connected to the water and gas passage 1012. This arrangement optimizes the water inlet and air return structure of the no-clean drum washing machine with a drying function, so that the common water and gas passage 1012 is passed into the interior of the non-porous washing drum 2, the rotatable water pipe 1025 is externally connected to the water inlet pipe 1020, and the rotatable air pipe 1026 is externally connected to the air pipe (the pipe at the rear end of the air duct).

[0062] As a preferred example of the present application, a door handle 1018 is provided on the door assembly at a side away from the hollow hinge assembly 1011, and a door handle buckle 1019 is provided on the outer tube 1 at a position corresponding to the door handle 1018. As an example of the present application, the center position of the hollow hinge assembly 1011 and the door handle 1018 are symmetrically arranged on opposite sides of the length direction of the water and gas passage 1012. This arrangement facilitates the door assembly to rotate around the hinge seat 1024 through the hinge 1023, making it convenient to take and put clothes.

[0063] As a preferred example of the present application, a detachable filter assembly is provided at the connection between the rotatable air pipe 1026 and the rear end 12 of the air duct. As an example of the present application, the detachable filter assembly includes a detachable filter 1021 and a detachable filter seat 1022. When the washing-free drum washing machine with a drying function dries clothes, hair scraps and the like circulate through the air duct assembly during gas circulation, and the detachable filter assembly can be intercepted and deposited, and the user can disassemble the detachable filter at regular intervals for cleaning.

[0064] As a preferred example of the present application, the condensation device includes a condensation chamber 17, and the humid air in the porous washing drum 2 is condensed in the condensation chamber 17. The condensed water flows to the external drainage pipe 5 through the small drainage pipe 18 on the condensation chamber 17. The condensed gas enters the air duct heating system 11 through the front end 9 of the air duct under the action of the fan 10, and then flows through the rear end 12 of the air duct into the porous washing drum 2 after being heated.

[0065] The heated air at the rear end 12 of the air duct can enter the porous washing drum 2 through the hollow hinge assembly 1011 or the air inlet 15 on the front door sealing ring 13 to circulate, heat and dry the clothes. The condensing device is used to cool the moist air after drying. Combined with the small drainage pipe 18, the condensed water in the circulating air duct flows to the external drainage pipe 5, which helps to effectively separate the water in the drying gas and ensure that the moisture no longer flows into the porous washing drum 2. The hot air can be reused through the air duct heating system 11, thereby improving the drying effect of the no-clean drum washing machine and improving the drying efficiency.

[0066] As an example of the present invention, the condensation chamber 17 is water-cooled condensation or heat pump condensation. Preferably, a condensation water pipe 16 is provided at the upper end of the condensation chamber 17 for introducing water into the condensation chamber 17. This arrangement facilitates the regulation of the working conditions of the condensation chamber 17, thereby affecting the condensation effect of moisture and improving the drying performance of the no-clean drum washing machine.

[0067] As a preferred example of the present utility model, a second filter 19 is arranged on the front end 9 of the air duct near the front end of the condensation chamber 17, and the second filter 19 is detachably connected to the gas pipeline of the front end 9 of the air duct, or the second filter 19 is installed in the condensation chamber 17, and the second filter 19 is reversely flushed through the flushing pipeline 20, and the water after flushing flows to the drain pipe 5 along the small drainage pipe 18.

[0068] This arrangement further ensures that the gas in the air duct system remains relatively clean and improves the performance and maintainability of the washing machine by arranging a second filter 19 at a position close to the condensation chamber 17 on the front end 9 of the air duct and providing two different configurations.

[0069] Preferably, a drainage pump 6 is arranged on the external drainage pipe 5. This arrangement further ensures the reliability of the wash-free drum washing machine with a drying function to discharge washing water or condensed water to the outside.

[0070] As a preferred example of the present invention, the rotation center axis of the non-porous washing drum 2 can be set horizontally, or can be set obliquely downward from the opening side to the rear end of the non-porous washing drum 2.

[0071] This arrangement ensures that the clothes will not enter the gas flow hole at the center of the rear end of the non-porous washing drum 2 in the washing state and the dehydration state, thereby ensuring the performance of the washing and drying work of the clothes.

[0072] As a preferred example of the present application, the wash-free drum washing machine with drying function described in the present application has a hole-free side of the non-porous washing drum 2, and only a drain switch 4 is provided on the inner part of the water-repellent rib 3. The drain switch 4 is a centrifugal drain switch. When washing, the non-porous washing drum 2 rotates at a low speed, and the drain switch 4 is in a closed state. When dehydrating, the non-porous washing drum 2 rotates at a high speed, and the drain switch is in an open state. The water in the non-porous washing drum 2 is discharged to the outside of the washing drum and discharged from the drain pipe 5 and the drain pump 6. In the drying system, under the action of the fan 10, a negative pressure is generated at the front end 9 of the air duct, and the humid gas in the non-porous washing drum 2 enters the filter device 7 through the gas flow hole in the center of its rear end, and then enters the cavity between the inner and outer drums, and enters And through the outer cylinder exhaust port 8 to the front end 9 of the air duct, in the air duct condensation chamber 17, it partially condenses into water after being cooled, and is discharged to the drain pipe 5 through the small drainage pipe 18; the cooled gas enters the rear end 12 of the air duct with the action of the fan 10, and is heated under the action of the air duct heating system 11. The heated dry air passes through the rear end 12 of the air duct, and then passes through the air inlet 15 at the front door sealing ring 13 to the inclined surface of the glass door 14, and is refracted into the non-porous washing drum 2. Alternatively, the heated air at the rear end 12 of the air duct passes through the hollow hinge assembly 1011 and the water vapor passage 1012 from the center of the inner rotating door 1016 into the non-porous washing drum 2, and then encounters the humid load, becomes high-temperature, humid air, and circulates continuously to discharge the water in the load to the outside of the machine.

[0073] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
