Description

Technical Field

[0001] The invention belongs to the technical field of household appliances, and in particular relates to a water inlet structure for a washing machine. Background Art

[0002] A washing machine is a cleaning appliance that uses electrical energy to generate mechanical action to wash clothes. Currently, washing machines mainly include pulsator washing machines and drum washing machines;

[0003] The existing drum washing machine mainly includes a casing, an outer drum arranged in the casing, an inner drum rotatably arranged in the outer drum, and a water inlet pipe. A water inlet valve is arranged on the water inlet pipe. An annular window gasket for sealing the gap between the casing and the outer drum is arranged between the casing and the barrel opening of the outer drum. The inner periphery of the annular window gasket forms a water inlet cavity. The water outlet of the water inlet pipe is arranged above the window gasket and communicates with the water inlet cavity. Water is fed into the outer drum through the water inlet cavity. During the water inlet process, a closed space is formed in the water inlet pipe, so that negative pressure is generated in the water inlet pipe. After the water inlet valve stops feeding water, the water in the water inlet pipe cannot completely fall down by gravity due to the negative pressure in the water inlet pipe, resulting in water remaining in the water inlet pipe, thereby causing water to drip outside the door of the washing machine after the washing machine door is opened, affecting the user experience. In addition, if the residual water in the water inlet pipe is not removed for a long time, the water inlet pipe will become moldy, thereby corroding the water inlet pipe.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] like Figure 1 and Figure 2As shown, the present invention provides a water inlet structure for a washing machine, comprising an annular window gasket 2 and a water inlet pipe 3. The inner periphery of the annular window gasket 2 forms a water inlet cavity for letting water into the washing machine. A water outlet 33 of the water inlet pipe 3 is arranged on the annular window gasket 2 and is connected with the water inlet cavity. An air hole 34 connected with the outside atmosphere is arranged upstream of the water outlet 33 of the water inlet pipe 3.

[0034] In the embodiment of the present invention, an air hole 34 is provided upstream of the water outlet 33 of the water inlet pipe 3, so that the water inlet pipe 3 can always keep in communication with the outside atmosphere, so that the pressure in the water inlet pipe 3 is balanced, so that after the water inlet pipe 3 stops inletting water, the water in the water inlet pipe 3 can be discharged from the water outlet 33 of the water inlet pipe 3 into the water inlet cavity, thereby preventing residual water in the water inlet pipe 3, thereby preventing the residual water in the water inlet pipe 3 from dripping to the outside of the washing machine door when the washing machine door is opened, and preventing the residual water from corroding the water inlet pipe 3.

[0035] The washing machine is a drum washing machine, which includes a casing 9, an outer drum 1 arranged in the casing 9 and an inner drum arranged in the outer drum 1. The outer drum 1 is a water storage drum. A water inlet valve 7 is arranged on the casing 9. A water inlet pipe 3 is arranged on the water inlet valve 7. The water inlet valve 7 controls the external washing water to enter the water inlet pipe 3. An annular window pad 2 is arranged between the clothing delivery inlet provided on the casing 9 and the tube mouth of the outer drum 1. The annular window pad 2 is coaxially arranged with the inner drum, the outer drum 1 and the clothing delivery inlet. The inner periphery of the annular window pad 2 forms a water inlet cavity. The water outlet 33 of the water inlet pipe 3 is arranged at the top of the peripheral wall of the window pad. The water outlet 33 of the water inlet pipe 3 is connected with the water inlet cavity. When water is inletted, the washing water enters the water inlet cavity from the water inlet pipe 3 and then enters the outer drum 1 from the water inlet cavity. The water inlet cavity enters the outer drum 1, which is actually the gap between the outer drum 1 and the inner drum.

[0036] The casing 9 is square, the front side wall of the casing 9 is provided with a clothing loading port, the rear side wall of the casing 9 is provided with a water inlet valve 7, the water inlet valve 7 and the water inlet pipe 3 are arranged in the casing, the water inlet of the water inlet valve 7 passes through the rear side wall of the casing 9, and the water inlet pipe 3 extends from the rear side of the casing 9 to the front side of the casing 9; the annular window pad 2 is arranged on the front side of the washing machine, and the clothing loading port is located on the front side of the washing machine;

[0037] In an embodiment of the present invention, the water inlet pipe 3 includes a water inlet section 31 which is arranged above the annular window pad 2 and extends along the axial direction of the annular window pad 2. The water outlet 33 of the water inlet pipe 3 is arranged at the water outlet end of the water inlet section 31. The water outlet end of the water inlet section 31 extends toward the annular window pad 2, and the air vent is arranged on the water inlet section 31.

[0038] In the embodiment of the present invention, specifically, the water inlet section 31 is arranged above the outer cylinder 1, the water inlet end of the water inlet section 31 is first bent radially to the left, and then bent axially backward to form an auxiliary water inlet section 32, and the free end of the auxiliary water inlet section 32 is provided with a water inlet valve 7; the water outlet end of the water inlet section 31 is first bent radially to the left, and then bent axially forward to form a first water inlet section, and the water outlet end of the first water inlet section is bent radially downward to form a second water inlet section, the first water inlet section and the second water inlet section are connected via a connector, the second water inlet section is a hose, the first water inlet section, the water inlet section 31 and the auxiliary water inlet section 32 are hard pipes, all of which are located on the left side of the top of the outer cylinder 1, and the first water inlet section and the auxiliary water inlet section 32 are located above the water storage cylinder; the second water inlet section extends radially and extends downward to the top of the annular window pad 2, which is conducive to water entering the water inlet cavity according to its own gravity and avoiding water residue; the water inlet pipe 3 is arranged in this way, so that the water inlet pipe 3 can fully utilize the space above the outer cylinder 1 while filling the water into the water inlet cavity;

[0039] Preferably, the air vent is arranged near the water inlet end of the water inlet section, so that the air vent can ventilate the water inlet pipe 3 from the water inlet end of the water inlet pipe 3, so that the incoming water is not affected by the water inlet resistance from the beginning and can flow smoothly in the water inlet pipe 3;

[0040] Furthermore, the water inlet structure also includes a three-way pipe 4, which includes a main pipe 41 coaxial with the water inlet section 31 and a side pipe 42 arranged at the bottom of the main pipe 41. The water inlet section 31 is divided into a first part 311 and a second part 312 along the axial direction of the water storage cylinder. The water inlet end of the main pipe 41 is connected to the first part 311, and the water outlet end of the main pipe 41 is connected to the second part 312. The outlet of the free end of the side pipe 42 serves as a vent.

[0041] The second part 312 is integrally formed with the first water inlet section, the first part 311 is integrally formed with the auxiliary water inlet section 32, the first part 311 and the second part 312 are connected by the main pipe 41, and the auxiliary pipe is connected to the outside atmosphere or other pipelines.

[0042] In the embodiment of the present invention, the water inlet structure further includes a water blocking structure 5 for preventing the water flowing through the water inlet section 31 from flowing outward from the air vents.

[0043] In the embodiment of the present invention, in order to prevent the water flowing through the water inlet section 31 from leaking from the vent hole to the outside atmosphere or leaking to other connecting pipes, a water blocking structure 5 is provided at the vent hole. The water blocking structure 5 may be a control valve or other non-valve structure for opening and closing the vent hole.

[0044] like Figure 3 and Figure 4As shown, further, the connecting part between the main pipe 41 and the side pipe 42 divides the main pipe 41 into a first main section 411 at the water inlet end of the main pipe 41 and a second main section 412 at the water outlet end of the main pipe 41, and the side pipe 42 extends obliquely from top to bottom gradually approaching the first main section 411, and the angle between the side pipe 42 and the first main section 411 is an acute angle, and the inclined side pipe 42 serves as a water blocking structure 5.

[0045] The first main section 411 is coaxially arranged with the first part 311, and the second main section 412 is coaxially arranged with the second part 312. A first limiting protrusion is arranged on the periphery of the first main section 411, and a second limiting protrusion is arranged on the periphery of the second main section 412. The first main section 411 is inserted into the first part 311, and the end face of the first part 311 abuts against the end face of the first limiting protrusion. The second main section 412 is inserted into the second part 312, and the end face of the second part 312 abuts against the end face of the second limiting protrusion, thereby improving the assembly strength between the first main section 411 and the first part 311 and the assembly strength between the second main section 412 and the first part 311.

[0046] The side tube 42 is arranged at an angle, and the inclined side tube 42 is used as a water blocking structure 5. The angle between the side tube 42 and the first main section 411 is 45°. Since the first main section 411 is the water inlet end of the main tube 41, the flow direction of water in the first main section 411 is opposite to the extension direction of the side tube 42, so that water will not enter the side tube 42, and then water will not leak from the water permeable hole.

[0047] Preferably, the inclined side tube 42 is divided into a first side section 421 and a second side section 422 along its extension direction. The first side section 421 is connected to the main tube 41 , and the second side section 422 is provided with a vent hole. The inner diameter of the first side section 421 is smaller than the inner diameter of the second side section 422 .

[0048] The inner diameter of the first side section 421 is smaller than the inner diameter of the second side section 422, so that the inner diameter of the first side section 421 is relatively small, so that the first side section 421 has relatively large resistance to water, and water will preferentially enter the second main section 412 from the first main section 411, and will not enter the first side section 421; a through hole connected to the side section is provided on the main section, and the radial dimension of the through hole is equal to the dimension of the inner diameter of the first side section 421, so that the size of the through hole is relatively small.

[0049] like Figure 1 As shown, in the embodiment of the present invention, a ventilation tube 6 connected to the outside atmosphere is provided on the water drum of the washing machine, an air outlet is provided at the free end of the ventilation tube 6, and a side tube 42 is connected to the ventilation tube 6 through an opening at the free end of the side tube 42, and the connection point between the side tube 42 and the ventilation tube 6 is located upstream of the air outlet of the ventilation tube 6.

[0050] In the embodiment of the present invention, the provision of the air-permeable tube 6 enables the outer tube 1 to be connected to the outside atmosphere, thereby achieving air permeability to the outer tube 1 and balancing the pressure inside the outer tube 1;

[0051] The side pipe 42 is connected to the ventilation pipe 6, so that the water inlet pipe 3 is ventilated by the ventilation pipe 6, thereby integrating the ventilation of the water inlet pipe 3 and the ventilation of the outer tube 1, reducing the number of ventilation pipes 6 and reducing the occupation of the internal space of the casing 9;

[0052] Furthermore, the air permeable tube 6 includes an air permeable section 61 extending along the axial direction of the annular window gasket 2, the air permeable section 61 is arranged above the annular window gasket 2 and below the water inlet section 31, and is directly opposite to the water inlet section 31, and the side tube 42 extends downwardly and obliquely to the peripheral wall of the air permeable section 61. Specifically, the entire air permeable tube 6 is arranged above the outer tube 1 and is located on the left side of the top of the outer tube 1.

[0053] Furthermore, a communication hole facing upward is provided on the peripheral wall of the ventilation section 61, and an auxiliary ventilation section 62 is provided at the communication hole. The auxiliary ventilation section 62 is coaxially arranged with the side tube 42, and the side tube 42 is connected with the auxiliary ventilation section 62 through the ventilation hole.

[0054] In the embodiment of the present invention, the air outlet end of the air permeable section 61 and the water inlet end of the water inlet section 31 both extend back to the annular window pad 2, the air outlet end of the air permeable section 61 extends beyond the water inlet end of the water inlet section 31, the water inlet end of the water inlet section 31 is provided with a water inlet valve 7, the air outlet of the air pipe 6 is provided at the air outlet end of the air permeable section 61, the air outlet end of the air permeable section 61 is provided with a radiator arranged side by side with the water inlet valve 7, the radiator has a radiator outlet connected to the outside atmosphere, and the radiator outlet serves as an air vent 34.

[0055] The front end of the air permeable section 61 is bent to the left and then bent downward to form a first air permeable section, and the lower end of the first air permeable section is connected to the outer tube 1; the rear end of the air permeable section 61 extends backward to exceed the rear end of the water inlet section 31, the rear end of the water inlet section 31 is the water inlet end of the water inlet section 31, and the rear end of the air permeable section 61 is the air outlet end of the air permeable section, so that a avoidance space is formed between the air permeable section 61 and the water inlet section to provide a radiator; the air permeable section 61 crosses the auxiliary water inlet section 32 below the auxiliary water inlet section 32.

[0056] In the embodiment of the present invention, the air permeable tube 6 is connected to the outside atmosphere via the radiator 8, so that the radiator 8 can not only dissipate heat and condense the steam generated inside the outer drum, and discharge the condensed steam into the outside atmosphere, but also ventilate the water drum with the outside to balance the pressure between the water drum and the outside atmosphere, so that the radiator 8 integrates the functions of heat dissipation, condensation and ventilation, thereby simplifying the structure of the drum washing machine.

[0057] For example, when the drying program is executed in the washing machine, steam is generated in the outer drum 1, and the pressure in the outer drum 1 is relatively high. The outer drum 1 is connected to the outside atmosphere through the air pipe 6 and the radiator 8, so that the outer drum 1 and the outside atmosphere are ventilated to balance the pressure; at the same time, the radiator 8 dissipates heat and condenses the steam generated in the outer drum 1, and the steam is discharged into the outside atmosphere after condensation. The condensed water generated by the heat dissipation and condensation can flow back to the outer drum 1 through the air pipe 6.

[0058] For another example, since there is often an odor in the washing machine after it has not been used for a long time, the outer tub 1 is connected to the outside atmosphere through the air vent 6 and the radiator 8 to achieve ventilation between the outer tub 1 and the outside atmosphere, which can remove the odor inside the outer tub 1.

[0059] like Figure 5-7 As shown, in the embodiment of the present invention, a heat dissipation cavity 83 is formed inside the radiator 8 , and the heat dissipation cavity 83 has an air outlet connected to the outside atmosphere, and the air outlet of the air permeable tube 6 is connected to the inside of the heat dissipation cavity 83 .

[0060] In the embodiment of the present invention, the air outlet of the air permeable tube 6 is connected to the outside atmosphere through the heat dissipation cavity 83. The heat dissipation cavity 83 provides space for the heat dissipation and condensation of steam, delays the discharge of steam, and enables the steam to be fully heat dissipated and condensed in the heat dissipation cavity 83.

[0061] The interior of the heat dissipation cavity 83 is provided with a serpentine heat dissipation channel 831, and the two ends of the heat dissipation channel 831 are respectively provided with an air inlet connected to the air vent pipe 6 and an air outlet connected to the outside atmosphere. The air outlet of the heat dissipation cavity 83 serves as the air outlet of the heat dissipation channel 831, and the air inlet and air outlet of the heat dissipation channel 831 are respectively arranged on the front and rear sides of the heat dissipation cavity 83. The heat dissipation channel air outlet 8313 serves as the air outlet of the radiator 8, thereby serving as the air vent 34 of the water inlet pipe.

[0062] The steam enters the serpentine heat dissipation channel 831 and dissipates heat and condenses in the serpentine heat dissipation channel 831. The heat dissipation channel 831 is serpentine, which increases the length of the heat dissipation channel 831, so that the steam stays in the heat dissipation channel 831 for a longer time to dissipate heat and condense, so that the steam can fully dissipate heat and condense. The steam collides and contacts the side walls of the heat dissipation channel 831 with a relatively low temperature, and the heat is dissipated from the heat dissipation channel 831 to the outside of the heat dissipation cavity 83. The condensed water condenses on the side walls of the heat dissipation channel 831, and most of it eventually flows to the bottom wall of the heat dissipation channel 831.

[0063] The front side of the heat dissipation cavity 83 is the side of the washing machine where the outer drum 1 is located. The air inlet and outlet of the heat dissipation channel 831 are respectively arranged on the front and rear sides of the heat dissipation cavity 83 to increase the length of the condensation channel.

[0064] In an embodiment of the present invention, a plurality of heat dissipation baffles are provided inside the heat dissipation cavity 83, and the plurality of heat dissipation baffles divide the interior of the heat dissipation cavity 83 into a plurality of strip flow channels 8311 arranged in sequence front to back, each strip flow channel 8311 extends left to right, and the head and tail ends of the plurality of strip flow channels 8311 are connected to form a heat dissipation flow channel 831, and the air inlet and air outlet of the heat dissipation flow channel 831 are respectively arranged at the front side of the frontmost strip flow channel and the rear side of the rearmost strip flow channel.

[0065] In an embodiment of the present invention, for example, a first heat dissipation baffle located at the frontmost side, a second heat dissipation baffle located at the rearmost side are provided in the heat dissipation cavity 83, then four strip flow channels are formed in the heat dissipation cavity 83, namely, a first strip flow channel located at the frontmost side, a second strip flow channel, a third strip flow channel and a fourth strip flow channel located at the rearmost side, the right tail end of the first strip flow channel is connected to the right head end of the second strip flow channel, the left tail end of the second strip flow channel is connected to the left head end of the third strip flow channel, the right tail end of the third strip flow channel is connected to the right head end of the fourth strip flow channel, each strip flow channel extends left and right, the heat dissipation flow channel air inlet 8312 is provided on the front side wall of the first strip flow channel, and is located between the left head end and the right tail end of the first strip flow channel, the heat dissipation flow channel air outlet 8313 is provided on the rear side wall of the fourth strip flow channel, and is located between the right head end and the left tail end of the fourth strip flow channel;

[0066] Furthermore, the heat dissipation cavity 83 is square, and the heat dissipation baffle is square. Among two adjacent heat dissipation baffles, the left side wall of one heat dissipation baffle and the left side wall of the heat dissipation cavity 83, the top wall of the heat dissipation cavity and the bottom wall 834 of the heat dissipation cavity form a left main connecting port 832, and the right side wall of the other heat dissipation baffle and the right side wall of the heat dissipation cavity 83, the top wall of the heat dissipation cavity and the bottom wall 834 of the heat dissipation cavity form a right main connecting port 833. The left main connecting port 832 and the right main connecting port 833 respectively connect the head and tail ends of two adjacent strip flow channels 8311.

[0067] Specifically, the front side wall of the first heat dissipation baffle, the left and right side walls of the heat dissipation cavity 83 and the front side wall of the heat dissipation cavity 83 form a first strip-shaped flow channel, the rear side wall of the first heat dissipation baffle, the left and right side walls of the heat dissipation cavity 83 and the front side wall of the second heat dissipation baffle form a second strip-shaped flow channel, the rear side wall of the second heat dissipation baffle, the left and right side walls of the heat dissipation cavity 83 and the front side wall of the third heat dissipation baffle form a third strip-shaped flow channel, and the rear side wall of the third heat dissipation baffle, the left and right side walls of the heat dissipation cavity 83 and the rear side wall of the heat dissipation cavity 83 form a fourth strip-shaped flow channel;
