Description

Technical Field

[0001] The present invention relates to the technical field of washing machines, and in particular to a water inlet system and a drum washing machine. Background Art

[0002] As the functions of washing machines increase, detergents, softeners, and disinfectants are added to the washing tub of the washing machine as needed when washing clothes. Even many washing machines have added heat pump systems to achieve the drying function of the washing machine. At present, the drying methods of conventional drum-type washing and drying machines are divided into heat pump type and condensing type.

[0003] Among them, the water inlet system of a conventional drum-type heat pump washer-dryer is relatively independent and can only realize the water inlet function of the washing machine.

[0004] In addition, the drum heat pump washer-dryer needs to be cleaned after each drying process or after a period of use. That is, the lint filter is manually removed from the machine, and then the lint on the filter is cleaned. After cleaning, the filter is installed back to its original position. If the filter is not cleaned in a timely and effective manner, it will affect the air volume of the drying external cycle and reduce the drying efficiency.

[0005] In the prior art, the water inlet structure of the water inlet system is arranged in the air duct and close to the filter, and the filter of the washing machine is self-cleaned while the washing machine is taking in water, thereby ensuring that the filter can be cleaned promptly and effectively. However, the above-mentioned structure is relatively complicated, and the water inlet volume and water inlet requirements of each route are different, resulting in many structures in the water inlet system being idle for a long time, resulting in a high cost of the water inlet system, and low application efficiency of each component, which is not convenient for the assembly of the water inlet system, and at the same time, the cost performance of the washing machine is slightly reduced, which is not convenient for product promotion. Summary of the invention

[0006] In view of this, the present invention aims to provide a water inlet system and a drum washing machine to solve at least one of the above-mentioned technical problems.

[0007] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0008] A water inlet system, comprising:

[0009] A water inlet valve, wherein the water inlet valve comprises two outlets, one of which flows to the condensation chamber through a first water pipe, and the other flows to the water distribution device through a connecting pipe;

[0010] The water distribution device is provided with two outlets, one of which is connected with the cylinder assembly through the second water pipe, and the other is connected with the filtering device on the drying device through the third water pipe.

[0011] Furthermore, the water diversion device includes a water diversion part and a liquid storage box, the water diversion part includes a water inlet end and a liquid outlet end, the water inlet end is connected to the connecting pipe of the water inlet valve, and the liquid outlet end is provided with two liquid outlets, which are respectively connected to the second water pipe and the third water pipe, wherein when the water flow in the water diversion device passes through the water diversion part and the second water pipe to flow into the barrel assembly, the detergent inside the liquid storage box can be drawn to the water diversion part and then flow to the barrel assembly through the second water pipe.

[0012] Furthermore, the detergent in the liquid storage box is pumped into the water diversion part by a delivery pump.

[0013] Furthermore, the water diversion portion is arranged at the front side or the rear side of the liquid storage box.

[0014] Furthermore, the water distribution part is integrated with the liquid storage box, and the outlet of the delivery pump for pumping detergent is connected to the distribution water path on the water distribution part which is connected to the second water pipe.

[0015] Furthermore, the distance between the outlet of the delivery pump for pumping detergent and the outlet on the water diversion part connected to the second water pipe is L, and L>20mm.

[0016] Furthermore, the cylinder assembly includes an inner cylinder and an outer cylinder, a coaxial cover of the outer cylinder is arranged on the outside of the inner cylinder and the inner cylinder can rotate relative to the outer cylinder, a condensation tray is arranged on the inner wall of the rear end of the outer cylinder, and the condensation chamber is formed between the condensation tray and the inner wall of the rear end of the outer cylinder. Under drying conditions, the water inlet valve passes through the first water pipe and flows into the condensation tray to condense the hot and humid air in the inner cylinder.

[0017] Furthermore, a drying device is arranged on the outer wall of the outer cylinder, and the drying device includes a filtering device, a fan, a heating device and a drying air duct which are arranged in sequence. The drying air duct is used to transport the air condensed in the condensation chamber to the heating device under the action of the fan for heating and then flows to the inner cylinder of the cylinder assembly.

[0018] Furthermore, the filtering device is arranged below the fan, and the water from the water distribution device flowing to the filtering device through the third water pipe washes the filter screen in the filtering device from top to bottom.

[0019] Compared with the prior art, the water inlet system of the present invention has the following advantages:

[0020] (1) The water inlet system of the present invention integrates the water inlet, drying and filtering functions of the washing machine, simplifies the design of the structure and components, reduces the component cost and assembly difficulty, reduces the space occupied by the water inlet system components, and improves the space utilization inside the washing machine.

[0021] (2) The water inlet system of the present invention uses a one-inlet and two-outlet water inlet valve as the main water inlet channel of the washing machine. One water inlet of the water inlet valve can flow into the condensation chamber to flush the condensation plate, and the other water inlet can flow into the drum assembly and the filter device respectively through a water distribution device integrating a water distribution part and a liquid storage box. At the same time, combined with the automatic injection function, the automatic injection of detergent is realized, the water inlet pipeline and the installation structure of the washing machine are optimized, the structure is compact, and the assembly is convenient. On the basis of ensuring the reliable water supply of the washing machine, the overall working performance of the washing machine is improved and the production cost of the washing machine is reduced.

[0042] Example 1

[0043] like Figures 1 to 11 As shown, the present invention discloses a water inlet system, comprising:

[0044] A water inlet valve 4, wherein the water inlet valve 4 comprises two outlets, one of which flows to the condensation chamber 6 through the first water pipe 8, and the other flows to the water distribution device 5 through the connecting pipeline;

[0045] The water distribution device 5 is provided with two outlets, one of which is connected to the cylinder assembly 3 through the second water pipe 9, and the other is connected to the filtering device 71 on the drying device 7 through the third water pipe 10.

[0046] The water inlet system described in the present application aims to solve the problems of complex structure, high cost and low efficiency of the water inlet system of the washing machine in the prior art. The water inlet components of the water inlet system are divided into a water inlet valve 4 and a water distribution device 5 to realize water distribution, thereby realizing the integration of the water inlet, drying and filtering functions of the washing machine, and simplifying the design of the structure and components. By combining the water inlet valve with the water distribution device, and selecting a suitable water pipe diameter according to the required water flow, detergents, softeners, etc. can be added to the washing barrel of the washing machine as needed, and water is diverted to the condensation chamber and the drum assembly to meet the needs of washing and drying, and to ensure the self-cleaning of the filter device 71 in the drying duct to avoid the accumulation of hair debris and the decrease in drying efficiency. In addition, the water inlet valve and the water distribution device can be separately arranged according to the external structure of the drum assembly 3, thereby reducing the space occupied by them and improving the space utilization rate inside the washing machine.

[0047] The water inlet system described in the present application simplifies the structure and improves efficiency, reduces component costs and assembly difficulty, and at the same time improves the performance and practicality of the washing machine.

[0048] As a preferred example of the present application, the water distribution device 5 includes a liquid storage box 51 and a distribution box 52, the liquid storage box 51 includes a water inlet end and a liquid outlet end, the water inlet end is connected to the connecting pipe of the water inlet valve 4, and the liquid outlet end is provided with two outlets, which are respectively connected to the second water pipe 9 and the third water pipe 10. When the water flow in the water distribution device 5 passes through the liquid storage box 51 and the second water pipe 9 to flow into the barrel assembly 3, the detergent inside the distribution box 52 can be extracted into the liquid storage box 51 and then flow to the barrel assembly 3 through the second water pipe 9.

[0049] This arrangement combines the water distribution device 5 with the automatic detergent delivery function, realizes the distribution and delivery control of the detergent according to the water inlet waterway of the water inlet system, ensures the washing effect during the washing process, and improves the washing quality, and realizes the diversion and control of water flow at the two ports of the liquid storage box 51, ensuring the efficiency of the water inlet system in supplying water to the filter device 71 and the barrel assembly 3 and the reliability of its operation.

[0050] As a preferred example of the present application, the detergent in the distribution box 52 is pumped into the liquid storage box 51 by the delivery pump 53. This setting ensures the reliability of the water inlet function and the automatic delivery function. By using the delivery pump 53 to draw the detergent in the distribution box 52 into the liquid storage box 51, the function of automatic delivery of detergent can be realized. When the user selects the corresponding washing program, the detergent will be automatically drawn and mixed with the water flow, thereby achieving an enhanced washing effect; in some cases, the user may only need to perform ordinary water washing. In this case, the delivery pump 53 can be turned off to prevent the detergent in the distribution box 52 from being drawn into the liquid storage box 51, thereby ensuring the purity and reliability of the water inlet. This setting allows different functions of the washing machine to be selected as needed, providing more flexibility and selectivity.

[0051] As a preferred example of the present application, the liquid storage box 51 is arranged at the front side or the rear side of the distribution box 52. Regardless of whether the liquid storage box 51 is arranged at the front side or the rear side of the distribution box 52, the delivery of detergent and the distribution of water flow can be effectively controlled, thereby improving the washing effect and meeting the different needs of users.

[0052] Specifically, as an example of the present application, the liquid storage box 51 and the distribution box 52 are integrated, the outlet of the delivery pump 53 for pumping detergent is connected to the distribution water path on the liquid storage box 51 that is connected to the second water pipe 9, and the distance between the outlet of the delivery pump 53 for pumping detergent and the outlet on the liquid storage box 51 that is connected to the second water pipe 9 is L, L>20mm. This setting ensures that the detergent can be fully mixed during the delivery process, and provides an optimized distribution water path to achieve effective use of the detergent and improve the washing effect; at the same time, the integrated setting of the liquid storage box 51 and the distribution box 52 has a tight structural connection, ensuring that the detergent can be smoothly transported from the distribution box 52 to the liquid storage box 51, effectively avoiding leakage or waste of the detergent during the delivery process, and providing a stable and reliable supply of detergent.

[0053] As a preferred example of this application, Figures 4 to 9 As shown, the water distribution device 5 includes a liquid storage box 51, a distribution box 52 and a delivery pump 53. The liquid storage box 51 can store a certain amount of detergent. The liquid outlet pipe of the liquid storage box 51 is connected to the inlet side 532 of the delivery pump 53, and the outlet side 531 of the delivery pump 53 is connected to the liquid inlet 5216 of the distribution box 52. The distribution box 52 has a water inlet 5213 and a liquid outlet 5214. The liquid outlet 5214 is connected to the second water pipe 9. Therefore, under the action of the delivery pump 53, the detergent is transported to the inside of the distribution box 52, and clean water enters the distribution box 52 through the water inlet 5213. As the clean water flows, it is mixed with the detergent and transported to the inner cavity of the barrel assembly 3 through the liquid outlet 5214, thereby realizing the automatic delivery process of the clothing processing device.

[0054] The distribution box 52 is fixedly connected to the liquid storage box 51, and the liquid storage box 51 and the delivery pump 53 are respectively fixedly connected to the barrel assembly 3, so that the water distribution device with automatic delivery components is fixed to the barrel assembly 3 as a whole, which is convenient to install and has a stable connection.

[0055] The liquid storage box 51 is provided with a liquid level sensor 55 . The liquid level sensor 55 is provided on the liquid storage box 51 at a position close to the inlet side 532 and connected to the liquid storage box 51 , and is used to detect the liquid level inside the liquid storage box 51 .

[0056] As a preferred example of the present application, the distribution box 52 is provided with at least a water inlet 5213, a liquid inlet 5216, and a liquid outlet 5214. At least a first flow channel 525 is provided in the distribution box 52. One end of the first flow channel 525 is connected to the water inlet 5213, and the other end is connected to the liquid outlet 5214. The liquid inlet 5216 is connected to the first flow channel 525. The water inlet 5213 is connected to the water inlet valve 4, and the liquid outlet 5214 is connected to the second water pipe 9. Therefore, under the action of the delivery pump 53, the detergent stored in the liquid storage box 51 can be quantitatively transported to the first flow channel 525 of the distribution box 52, and then mixed with the water flow into the inner cavity of the barrel assembly 3.

[0057] At least one baffle 523 is arranged in the distribution box 52, so that the first flow channel 525 forms a baffle flow channel. One end of the baffle 523 is connected to the inner wall of the distribution box 52, and a check baffle 5231 is arranged at the other end. Therefore, the arrangement of the baffle 523 and the check baffle 5231 can effectively prevent the detergent in the first flow channel 525 from flowing back and avoid it from contaminating other structures in the distribution box 52.

[0058] The distribution box 52 is provided with a second flow channel 526 and a water outlet 5215. One end of the second flow channel 526 is connected to the water inlet 5213, and the other end is connected to the water outlet 5215. A partition plate 524 is provided between the first flow channel 525 and the second flow channel 526. The water outlet 5215 is connected to the third water pipe 10, and the filter device 71 on the drying device 7 is regularly rinsed and cleaned with clean water. This setting uses only one distribution box 52, and on the basis of automatically dispensing detergent using the first flow channel 525, a second flow channel 526 is further provided, and the first flow channel 525 and the second flow channel 526 are separated and independent from each other, meeting the separate water supply requirements for automatic dispensing, water inlet to the drum assembly, and cleaning of the filter device, optimizing the water inlet assembly of the washing machine, and being conducive to simplifying the component settings of the washing machine, and improving the functional integration of the distribution box 52 and other components.

[0059] Regarding the medium flow conditions in the first flow channel 525 and the second flow channel 526, regulating valves (not shown) can be set on the corresponding flow channels and medium flow pipelines, so that the washing machine can separately adjust the medium flow in the first flow channel 525 and the second flow channel 526.

[0060] The distribution box 52 may be an integral part having a corresponding flow channel structure inside, but in order to facilitate the production and processing of the distribution box 52 having an internal flow channel structure and reduce the production difficulty, the distribution box 52 includes a first box body 521 and a second box body 522, wherein the first box body 521 is connected to the second box body 522, a flow channel cavity is formed between the first box body 521 and the second box body 522, and a baffle 523 and a partition plate 524 are provided on the inner wall of the first box body 521 and / or the inner wall of the second box body 522, so that the flow channel cavity is divided into a first flow channel 525 and a second flow channel 526. Thus, by producing and processing the first box body 521 and the second box body 522 respectively, and then assembling the first box body 521 and the second box body 522, a distribution box 52 having a corresponding flow channel structure inside can be formed. The arrangement of each medium port of the distribution box 52 may be arranged in the first box body 521 or in the second box body 522, and this application does not make any specific restrictions.

[0061] A liquid inlet connector 54 is provided at the connection between the delivery pump 53 and the distribution box 52, a liquid inlet interface 5211 is provided on the outer wall of the distribution box 52, a liquid inlet port 5216 is provided in the liquid inlet interface 5211, one end of the liquid inlet connector 54 is communicated with the outlet side 531 of the delivery pump 53, and the other end is connected with the liquid inlet interface 5211, a valve cavity is formed between the liquid inlet connector 54 and the liquid inlet interface 5211, and a one-way valve assembly 56 is provided in the valve cavity. Thus, as the detergent flows from the delivery pump 53 to the distribution box 52, the one-way valve assembly 56 is provided between the liquid inlet connector 54 and the liquid inlet interface 5211, so that the detergent can only enter the distribution box 52, and the clean water and detergent in the distribution box 52 cannot flow back to the liquid inlet connector 54 and other components, which ensures the normal delivery and supply of the detergent on the one hand, and prevents the clean water and detergent from flowing back to the liquid inlet connector 54, the delivery pump 53 and other components from being polluted.

[0062] A second stud 5212 is disposed on the outer wall of the distribution box 52, and the second stud 5212 is disposed adjacent to the liquid inlet interface 5211. The liquid inlet connector 54 is connected to the second stud 5212 via fasteners while being assembled and connected to the liquid inlet interface 5211, thereby ensuring the reliability of the connection between the liquid inlet connector 54 and the distribution box 52, preventing the supply pipeline structure of the detergent from loosening, and facilitating avoiding leakage.

[0063] The one-way valve assembly 56 includes a valve body 561 and a valve core 562. The valve body 561 is provided with a liquid hole 5613. The valve core 562 is connected to the valve body 561. The valve cap 5621 of the valve core 562 is arranged on the side of the valve body 561 close to the distribution box 52. The valve cap 5621 of the valve core 562 can be deformed under the action of unilateral pressure to block or open the liquid hole 5613, so that when the delivery pump 53 delivers detergent to the distribution box 52, the detergent applies a force to the valve core 562 toward the inside of the distribution box 52, so that the valve core 562 is deformed, the liquid hole 5613 is opened, and the detergent enters the distribution box 52; when water is supplied through the first flow channel 525 in the distribution box 52 to deliver detergent, the water pressure will apply a force to the valve core 562 toward the liquid inlet joint 54, so that the valve core 562 blocks the liquid hole 5613 to avoid backflow. At the same time, when the detergent flows through the liquid hole 5613 of the valve body 561 , it can also provide a filtering effect to prevent foreign matter from entering the distribution box 52 .

[0064] A center hole 5612 is set at the center of the valve body 561, and an assembly column 5622 is set on the valve core 562. The assembly column 5622 passes through the center hole 5612. One end of the assembly column 5622 is connected to the valve cap 5621, and the other end is provided with a limiting protrusion 5623, so that the valve core 562 will not be separated from the valve body 561 under pressure, and the valve cap 5621 can maintain the sealing or opening of the liquid hole 5613.

[0065] An annular protrusion 5614 is provided on one side of the valve body 561 close to the distribution box 52, and the annular protrusion 5614 surrounds the outer side of the center hole 5612 and all the liquid holes 5613. The valve cap 5621 is provided with a flange 5624. When the valve core 562 blocks the liquid hole 5613, the flange 5624 can fit tightly with the outer wall of the annular protrusion 5614, thereby effectively improving the one-way on-off performance of the one-way valve assembly 56.

[0066] The one-way valve assembly 56 includes a sealing ring 563. An annular groove 5611 is provided on the outer edge of the valve body 561. The sealing ring 563 is sleeved in the annular groove 5611 and abuts against the inner wall of the liquid inlet connector 54 (interference fit) to improve the sealing performance of the one-way valve assembly 56 in the valve cavity and avoid leakage of detergent.

[0067] As a preferred example of the present application, the barrel assembly 3 includes an inner barrel 31 and an outer barrel 32, the outer barrel 32 is coaxially covered on the outside of the inner barrel 31 and the inner barrel 31 can rotate relative to the outer barrel 32, a condensation tray 61 is arranged on the inner wall at the rear end of the outer barrel 32, and the condensation chamber 6 is formed between the condensation tray 61 and the inner wall at the rear end of the outer barrel 32. Under drying conditions, the water inlet valve 4 flows into the condensation tray 61 through the first water pipe 8 to condense the hot and humid air in the inner barrel 31.

[0068] As a preferred example of the present application, this arrangement uses the water inlet of the water inlet valve 4 and the cooling effect of the condensation tray 61 to condense the hot and humid air into water on the side of the condensation tray 61 away from the rear wall of the outer cylinder 32. The condensed water on the condensation tray 61 and the water in the condensation chamber 6 flow from top to bottom toward the drainage device 11, thereby converting the moisture in the hot and humid air into liquid water, thereby quickly removing moisture from the clothes.

[0069] As a preferred example of the present application, a drying device 7 is arranged on the outer wall of the outer cylinder 32, and the drying device 7 includes a filter device 71, a fan 73, a heating device 74 and a drying air duct arranged in sequence, and the drying air duct is used to transport the air condensed in the condensation chamber 6 to the heating device 74 under the action of the fan 73 for heating and then flow to the inner cylinder 31 of the cylinder assembly 3. The condensed air is heated and circulated by the drying device 7, and the condensed air is first filtered by the filter device 71 to prevent hair scraps from entering the fan 73 or the heating device 74 to cause damage to the electrical components, thereby extending the service life of the drying device 7. A first drying air duct 72 is arranged between the fan 73 and the heating device 74, and the filtered air enters the heating device 74 through the first drying air duct 72 under the action of the fan 73 for heating, and the heated air finally enters the inner cylinder 31 through the second drying air duct 75, and the clothes in the inner cylinder 31 are dried again, so that the hot air can be efficiently used and the overall drying efficiency is improved.

[0070] As a preferred example of the present application, the filter device 71 is arranged below the fan 73, and the water from the water distribution device 5 flowing to the filter device 71 through the third water pipe 10 washes the filter screen in the filter device 71 from top to bottom. This arrangement ensures the reliability of the self-cleaning work of the filter screen and improves the working performance of the drying device 7.

[0071] The present invention also discloses a drum washing machine 100, comprising an outer shell assembly 1, a door cover assembly 2 and a barrel assembly 3, wherein the outer shell assembly 1 is arranged in a wrapped shape on the periphery of the barrel assembly 3, the door cover assembly 2 is covered on the front end of the barrel assembly 3, and the barrel assembly 3 is provided with a water inlet system as described in the above embodiment.

[0072] The water inlet system described in the present application uses a one-inlet and two-outlet water inlet valve 4 as the main water inlet channel of the washing machine. One water inlet of the water inlet valve 4 can flow into the condensation chamber 6 to flush the condensation plate 61, and the other water inlet passes through the water distribution device 5 of the integrated liquid storage box 51 and the distribution box 52, and can flow into the barrel assembly 3 and the filter device 71 respectively. At the same time, combined with the automatic injection function, automatic injection of detergent is realized, the water inlet pipeline and installation structure of the washing machine are optimized, the structure is compact, and the assembly is convenient. On the basis of ensuring the reliable water inlet of the washing machine, the overall working performance of the washing machine is improved and the production cost of the washing machine is reduced.

[0073] As a preferred example of the present application, the drum washing machine 100 is a wall-mounted drum washing machine, and the washing capacity of the drum washing machine 100 is less than 4kg. Preferably, the washing capacity of the drum washing machine 100 is 0.8kg to 1.5kg. Since the structure of the wall-mounted drum washing machine itself is relatively compact, the water inlet system of the traditional drum washing machine cannot meet the requirements of self-injection and drying functions, and the complex water inlet pipeline easily causes the overall size of the washing machine to become larger, which is not conducive to the user's home use. Through the above-mentioned improved water inlet system, the space inside the wall-mounted drum washing machine is fully utilized, the overall size of the wall-mounted drum washing machine is reduced, and the overall appearance is kept relatively round, which can be more integrated into the home environment and enhance the user's experience.

[0074] 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 principle of the present invention should be included in the protection scope of the present invention.
