Description

Technical Field

[0001] The present invention relates to a clothing processing device in a household appliance, specifically, to a clothing processing device having a hole-free drum and a drying function, and more particularly to a drum-type washer-dryer in which the drum is composed of a hole-free drum without dehydration holes, and more particularly to a door structure applied to the above-mentioned clothing processing device. Background Art

[0002] With the improvement of people's living standards, appliances such as washing and drying machines and clothes dryers with clothing drying functions have gradually entered the homes of the general public. However, existing washing and drying machines and clothes dryers generally have an air duct connected to the outer drum. The fan in the duct draws out the hot and humid air from the outer drum, thereby reducing the humidity inside the drum and drying the clothes.

[0003] Washing machines can be broadly classified into pulsator, agitator and drum types. Generally speaking, washing machines remove stains from laundry using the action of water and detergent.

[0004] Pulsator washing machines wash by rotating the pulsator in the center of the washing tub left and right. Agitator washing machines wash by rotating the rotating blades in the center of the washing tub left and right, utilizing the friction between the water flow and the laundry. Drum washing machines wash by rotating the drum, which tumbles the laundry.

[0005] A drum-type washing machine generally has a housing with an outer tub for containing washing water installed inside, a drum for containing laundry provided inside the outer tub, and a motor and shaft for rotating the drum provided on the back of the outer tub.

[0006] Nowadays, a large amount of dirt is generally retained between the inner and outer drums of washing machines, whether they are pulsator type or drum type. In order to avoid contamination of the washing water, the applicant has previously proposed a hole-free drum washing machine that combines the inner and outer drums into one to overcome the problem of dirt retained between the inner and outer drums.

[0007] Therefore, how to apply the hole-free drum technology to a washer-dryer with drying function has become a research and development hotspot.

[0008] At the same time, since the holeless drum needs to have its mouth closed and needs to rotate during the drying process, how to increase the air intake rate to the mouth of the rotatable holeless drum, especially the ventilation module installed at the mouth, has become a technical problem that needs to be solved urgently.

[0009] In view of this, the present invention is proposed. Summary of the Invention

DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0041] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limiting the present invention.

[0042] In the description of the present invention, it should be noted that, unless otherwise specified or limited, the terms "mounted" and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0043] like Figures 1 to 5 As shown, an embodiment of the present invention introduces a clothing processing device, which includes a drum 3 for independently holding washing water when washing clothes, thereby avoiding the problem of cross-flow of washing water inside and outside the drum 3 during the washing process of the washing machine, causing the washing water to be contaminated by dirt and bacteria accumulated outside the drum; a drying system for drying the load in the drum to obtain dry clothes, etc., thereby achieving the effect of improving the quality of life of users.

[0044] In an embodiment of the present invention, the drying system includes an air duct 4 which is connected to the drum 3 at both ends to form a circulating air path; a fan 40 is installed in the air duct 4, so that a circulating airflow flowing in a single direction is formed in the circulating air path formed by the drum 3 and the air duct 4; a dehumidification device 41 is also installed in the air duct 4 to dehumidify the circulating air flow flowing through it, so as to achieve the effect of reducing the humidity of the air flow in the circulating air path and drying the load in the drum 3; at the same time, in an embodiment of the present invention, in order to increase the drying rate of the load in the drum 3 and accelerate the vaporization of water adsorbed in the load, a heating device 42 can be set in the air duct 4 to heat the circulating air flow flowing through it, thereby achieving the effect of increasing the temperature in the drum 3, heating the load in the drum 3 and accelerating the drying rate.

[0045] In an embodiment of the present invention, when the clothes processing device executes a drying program, the drying system is controlled to start, and the fan 10 is used to form a circulating airflow in the circulating air path formed by the air duct 4 and the drum 3. When flowing through the drum 3, the circulating airflow fully contacts the load in the drum 3, carrying the moisture in the load and turning into moist hot drying air, which flows out of the drum 3 and into the air duct 4. After the moist hot drying air flows into the air duct 4, it contacts the dehumidification device 41 in the air duct 4, so that the moist hot drying airflow is converted into a dry drying airflow and then flows back into the drum 3, and the circulation continues in this way. Preferably, in order to increase the drying rate, a heating device 42 can be added to the air duct 4, so that the dry drying airflow after being dehumidified by the dehumidification device 41 contacts the heating device 42, is heated, and forms a high-temperature dry drying airflow before it flows back into the air duct.

[0046] In an embodiment of the present invention, the drying system can be any existing device capable of dehumidifying and drying clothing, such as a heat pump system. The heat pump system comprises a compressor, an evaporator, a throttling device, and a condenser connected end-to-end to form a circulation channel for circulating a cooling medium. A condenser and an evaporator are installed in the air duct 4 of the clothing processing device, arranged in sequence along the flow direction of the circulating airflow. This allows the airflow exiting the drum 3 to first undergo heat exchange with the evaporator to condense and separate the water vapor contained therein, then undergo heat exchange with the condenser to heat it and form a high-temperature dry airflow. Finally, the high-temperature dry airflow is returned to the drum 3 to reduce the humidity and increase the temperature in the drum 3, thereby achieving the effect of drying the load in the drum 3. Thus, the evaporator of the heat pump system constitutes the dehumidification device 41, and the condenser constitutes the heating device 42, thereby achieving the effect of drying the load in the drum.

[0047] In the embodiment of the present invention, in order to ensure that the drum 3 is rotatably installed in the housing 1 of the laundry processing device and is connected to the air duct 4 fixed in the housing 1, the following settings are performed:

[0048] like Figure 1As shown, in one embodiment of the present invention, a laundry processing device includes a housing 1, housing an outer drum 2. The outer drum 2 is connected to the washing machine housing 1 at the top and bottom via shock-absorbing suspension springs and shock-absorbing support rods, respectively, to ensure that the outer drum 2 can be vibrated within the washing machine housing 1. A coaxially mounted drum 3 is housed within the outer drum 2. The outer drum 2 and the drum 3 are respectively formed of a cylindrical outer drum sidewall 202 and a drum sidewall 302. Opposite openings are provided on corresponding ends of the outer drum 2 and the drum 3 on the same side, forming a drum opening 301 and an outer drum opening 201, respectively. The corresponding ends on the other sides are sealed, forming a drum bottom 303 and an outer drum bottom 203, respectively. Furthermore, an outwardly openable door 6 is mounted at the front end of the washing machine housing 1, allowing the outer drum opening 201 to be opened or closed by opening and closing the door 6. An outwardly openable drum door 7 is mounted on the drum 3, allowing the drum opening 301 to be opened or closed by opening and closing the drum door 7. Thus, the effect of installing a drum 3 within the outer drum 2, which can rotate relative to the outer drum 2 and forms a closed water container during washing, is achieved. The air duct 4 is connected to the outer drum 2 at both ends, and a ventilation hole is provided on the drum 3 that communicates with the outer drum 2. The ventilation module 5 is installed in the ventilation hole to achieve the purpose of forming a circulating air path through the air duct 4 through the outer drum 2 and the rotating drum 3, thereby drying the load in the drum 3.

[0049] In this embodiment of the present invention, the center of the drum bottom 303 is coaxially arranged with the motor shaft of the washing machine drive motor to drive the drum 1 to rotate. The drum 1 and the drive motor are both fixedly mounted on the outer drum 2. Preferably, the drum bottom 303 and the drive motor are respectively arranged on either side of the outer drum bottom 203. The drive motor is fixedly connected to the outer drum 2. The motor shaft of the drive motor passes through the outer drum bottom 203 via a bearing and is coaxially fixedly connected to the drum bottom 303. The motor shaft of the drive motor can rotate relative to the outer drum 2. This achieves the purpose of installing the drum 3 and the drive motor on the outer drum 2, allowing the drum 3 to rotate independently under the action of the drive motor to wash the clothes inside. Preferably, the motor shaft of the drive motor directly constitutes the drum axis, which is coaxially fixedly connected to the drum bottom 303 of the drum 3.

[0050] like Figures 1 to 5 As shown, this embodiment introduces a door structure of a clothing processing device, which includes a door body 6, a wind guide groove 60 protruding outward on one side of the door body 6, the protruding end of the wind guide groove 60 is open, and the opening constitutes an air outlet 62, and the outer peripheral side of the wind guide groove 60 is provided with an air inlet 61 composed of radial openings.

[0051] By arranging the above-mentioned air guide groove 60 on the door body 6 of the clothing processing device, the external airflow can be guided into the interior of the drum 3 through the air guide groove 60, thereby achieving the technical effect of significantly improving the gas fluidity of the clothing processing device during the drying process; at the same time, by arranging the above-mentioned air guide groove 60 on the door body 6, a significant technical progress is achieved in utilizing the door body 6 to guide the airflow and improve the air inlet efficiency of the drum 3.

[0052] Example 1

[0053] like Figures 1 to 4 As shown, this embodiment introduces a ventilation module 5, including a shell 54, which surrounds a hollow channel 53. Retaining ribs are arranged at both ends of the channel 53, and the retaining ribs separate the two ends of the channel 53 into a plurality of hollow holes 57, each hollow hole 57 connects the inside and outside of the channel 53.

[0054] Through the above-mentioned arrangement, the two sides of the ventilation module 5 can be connected through the hollow holes 57 of the connecting channels at both ends, so that the airflow on both sides of the ventilation module 5 can flow through the channels and achieve the purpose of free exchange and flow of gas on both sides under the action of pressure difference; at the same time, by arranging a plurality of hollow holes 57 arranged at intervals at the end of the ventilation module 5, the airflow flowing through can be evenly distributed under the action of the hollow holes 57, thereby improving the uniformity of the airflow flowing into the drum 3.

[0055] In this embodiment, the hollow holes 57 at both ends of the passage of the ventilation module 5 can be arranged in a staggered manner, so that the airflow does not pass directly through, but instead uses the return channel to pass through. This ensures that water trapped in the airflow is trapped by the return channel, effectively preventing the water from flowing out of the ventilation module. Of course, in this embodiment, the hollow holes 57 at both ends of the ventilation module 5 can also be arranged in any other manner, while still achieving the above-mentioned inventive objectives.

[0056] Preferably, in this embodiment, the projections of the hollow holes 57 at both ends of the channel 53 along the channel axis in the same vertical cross-section are at least partially staggered, so that the channel 53 of the breathable module 5 and the hollow holes 57 at both ends together form a folded gas flow channel, which can effectively intercept water trapped in the air flow and prevent water from flowing out of the breathable module 5.

[0057] like Figure 2 and Figure 3 As shown, in this embodiment, the cross-section of the channel 53 of the ventilation module 5 can be any shape, such as: circular, polygonal, elliptical, etc.; preferably, in this embodiment, in order to adapt to the shape of the drum 3, improve the ventilation efficiency, and improve the uniformity of the air flow, the ventilation module 5 can be set to be disc-shaped, and the cross-section of the ventilation channel 53 is set to be circular.

[0058] In this embodiment, the two ends of the circular channel 53 are respectively the first end 51 and the second end 52, and the first end 51 and the second end 52 are respectively provided with a retaining rib, which is used to separate the first end 51 and the second end 52 into a plurality of hollow holes 57, so that the two ends of the channel 53 can exchange airflow with the outside through the arranged hollow holes 57.

[0059] In this embodiment, the retaining ribs provided at the ends of the channel 53 can be configured in any shape and arrangement; for example, they can be configured as follows:

[0060] like Figure 2 and Figure 3 As shown, in this embodiment, a plurality of radial straight ribs 55 extending radially and arranged at intervals, and at least one annular rib 56 extending circumferentially are respectively provided at both ends of the circular channel 53; each radial straight rib 55 and each annular rib 56 are in the same cross-section, so that each radial straight rib 55 and each annular rib 56 are respectively connected one by one to each other, so that each radial straight rib 55 and each annular rib 56 divides the end of the channel 53 into a plurality of hollow holes 57 arranged at intervals in different circular rings.

[0061] Preferably, in this embodiment, the plurality of radial straight ribs 55 provided at the first end 51 and the second end 52 of the circular channel 53 are arranged at equal intervals and symmetrically about the axis of the channel 53 at the opposite ends.

[0062] Preferably, in this embodiment, the annular rib 56 is a circular annular rib 56 coaxially arranged with the end of the channel 53 and in the shape of a circular ring; further preferably, in this embodiment, the first end 51 and the second end 52 of the channel 53 are respectively provided with a plurality of concentric, unequal diameter circular annular ribs 56 to further increase the number of hollow holes 57 provided at the end of the channel 53.

[0063] In this embodiment, in order to achieve the staggered arrangement of the hollow holes 57 provided at both ends of the channel 53, the following settings can be made: the sizes of the annular ribs 56 provided at both ends of the channel 53 are not equal, so that the annular ribs 56 provided at the first end 51 and the second end 52 of the channel 53 are respectively in different circular cross-sections, and the projections of the annular ribs 45 provided at the first end 51 and the second end 52 of the channel 53 in the same vertical cross-section along the axis of the channel 53 are staggered and arranged in different concentric circles.

[0064] In order to further improve the degree of staggering of the hollow holes 57 provided at both ends of the channel 53, the following settings can also be made: the radial straight ribs 55 provided at both ends of the channel 53 extend along different radial directions, so that the radial straight ribs 55 provided at the first end 51 and the second end 52 of the channel 53 are arranged in different radial directions along the projections of the axis of the channel 53 in the same vertical section.

[0065] like Figures 2 to 4As shown, in this embodiment, the channel 53 is a tapered channel 53 with a gradually narrowing radial dimension from the first end 51 to the second end 52. The tapered sidewalls of the tapered channel 53 are used to guide water flowing into the channel 53 back toward the first end 51 of the channel, thereby effectively preventing water that accidentally flows into the channel 53 and is trapped from accumulating within the channel 53. In this embodiment, in order to achieve the effect that the trapped water in the channel 53 flows back toward the first end 51 and then flows into the washing machine drum, the channel 53 is installed on the drum 3 with the first end 51 facing the interior of the washing machine drum and the second end 52 facing the exterior of the washing machine drum, thereby preventing water from flowing out of the air vents.

[0066] In this embodiment, the inner peripheral wall of the first end of the channel 53 is provided with a plurality of hollow holes 57 arranged at intervals, so that the lowest point of the first end 51 of the channel 53 is the hollow hole 57, thereby ensuring that the water flow trapped in the channel 53 can flow back to the drum 3 through the lowest hollow hole 57 when it flows back to the first end 51 along the tapered side wall, further preventing the occurrence of water accumulation in the channel 53; at the same time, a circle of annular ribs 56 protruding toward the center of the channel is provided on the inner peripheral wall of the second end 52 of the channel, so that the annular ribs 56 can be used to block the inner periphery of the second end 52 of the channel 53, further ensuring that the water flow flowing into the channel 53 will not flow out from the second end 52, effectively reducing the possibility of water leakage from the breathable module 5.

[0067] like Figures 2 to 4 As shown, in this embodiment, a circular through hole is provided at the center of each end of the channel 53. The circular through hole is coaxial with the channel 53 and is located at the intersection of the radial straight ribs 55 at the corresponding end. By providing a circular through hole at the center of each end of the channel 53, the circular through hole can ensure direct ventilation, thereby improving the ventilation effect of the channel.

[0068] In this embodiment, the ventilation module 5 can be integrated with the drum 3 or separately. When the ventilation module 5 is separately installed from the drum 3, the following configuration is implemented: a circle of mounting ribs protruding radially outward are provided at the first end 51 of the channel 53 of the ventilation module 5. This rib provides one-way positioning of the ventilation module 5 and secures the ventilation module 5 to the ventilation hole. Furthermore, in this embodiment, a circular chamfered surface is provided at the outer periphery where the second end 52 of the channel 53 of the ventilation module 5 connects to the sidewall of the channel 53. This surface prevents problems such as pinching and scratching of clothing.

[0069] like Figures 1 to 5As shown, this embodiment also introduces a clothing processing device, which includes a drum 3 installed in the shell 1 and forming a sealed water container when the washing machine is in the washing state; at least one of the above-mentioned ventilation modules 5 is provided on the drum 3, so as to utilize the ventilation module 5 to exchange gas between the inside and outside of the drum 3, thereby achieving the purpose of ventilation between the drum 5 and the external air duct 4.

[0070] In this embodiment, at least one ventilation hole equipped with the aforementioned ventilation module 5 is provided at each of the opposing ends of the drum 3. These ventilation holes are connected, one-to-one, to the air inlet and outlet of the air duct 4 outside the drum 3. The ventilation module 5 provided at one end of the drum 3 is connected to the air inlet of the air duct 4; the ventilation module 5 provided at the other end of the drum 3 is connected to the air outlet of the air duct 4. Consequently, the ventilation modules 5 at different locations in the circulating air path formed by the drum 3 and the air duct 4 create a unidirectional circulating airflow, thereby ensuring the normal operation of the drying process. In this embodiment, the end of the drum 3 connected to the air outlet of the air duct 4 is provided with a tube opening.

[0071] In an embodiment of the present invention, the opposite ends of the drum 3 are the drum bottom 303 and the drum door 301, respectively. At least one of the above-mentioned ventilation modules 5 is respectively provided on the drum bottom 303 and / or the drum door 301. The ventilation modules 5 at both ends of the drum 3 are respectively connected to the air inlet end and the air outlet end of the air duct 4 outside the drum 3 in a one-to-one correspondence, so as to achieve the effect of forming a circulating air path.

[0072] In this embodiment, the ventilation module 5 can be integrated with the drum 3; of course, the ventilation module 5 can also be installed at the ventilation hole on the drum 3, for example as follows: the shell 54 of the ventilation module 5 corresponds to covering the ventilation hole assembled on the drum 3, and the outer periphery of the shell 54 is sealed and fitted with the inner wall of the ventilation hole; preferably, the shell 54 is sealed and fitted with the inner wall of the ventilation hole; further preferably, the outer periphery of the shell 54 protrudes from the ventilation hole and is in fit contact with the drum 3 at the outer periphery of the ventilation hole, thereby improving the assembly stability of the ventilation module 5.

[0073] In this embodiment, the two ends of the channel 53 formed by the shell 54 of the ventilation module 5 are respectively connected to the inside of the drum 3 and the outside of the drum 3; the first end 51 of the channel 53 of the ventilation module 5 faces the inside of the drum 3, and the second end 52 faces the outside of the drum 3, so as to ensure that the water flowing into the channel 53 is guided by the tapered side walls of the channel 53 and the retaining ribs provided at both ends, so that the accumulated water in the ventilation module 5 can flow back to the drum 3.

[0074] Example 2

[0075] like Figures 1 to 5As shown, this embodiment introduces a door structure of a clothing processing device, which includes a door body 6, a wind guide groove 60 protruding outward on one side of the door body 6, the protruding end of the wind guide groove 60 is open, and the opening constitutes an air outlet 62, and the outer peripheral side of the wind guide groove 60 is provided with an air inlet 61 composed of radial openings.

[0076] By arranging the above-mentioned air guide groove 60 on the door body 6 of the clothing processing device, the external airflow can be guided into the interior of the drum 3 through the air guide groove 60, thereby achieving the technical effect of significantly improving the gas fluidity of the clothing processing device during the drying process; at the same time, by arranging the above-mentioned air guide groove 60 on the door body 6, a significant technical progress is achieved in utilizing the door body 6 to guide the airflow and improve the air inlet efficiency of the drum 3.

[0077] In this embodiment, the door body 6 is a vertically arranged plate structure, and a protrusion protruding horizontally outward is provided on a vertical side surface of the door body 6, and the hollow space inside the protrusion constitutes an air guide groove 60;

[0078] Or, as Figure 5 As shown, a protrusion protruding horizontally outward is provided on a vertical side surface of the door body 6 , and the protrusion itself encloses a space, and the space enclosed by the protrusion constitutes the air guide groove 60 .

[0079] Thus, the protrusion on the door body utilizes its own internal hollow space and / or enclosed space to form an air guide groove, so as to achieve the technical effect of guiding the flow of air.

[0080] At the same time, in this embodiment, the protrusion can be formed integrally with the door body 6, or the protrusion can be composed of other independent parts that can be detachably installed on the door body 6.

[0081] In addition, in this embodiment, the protrusion can be made of a material such as glass that cannot produce deformation, or can be made of a material such as rubber that can produce deformation.

The air outlet 62 of the air guide groove 60 is opened toward the drum opening 301, so that the airflow flowing into the air guide groove 60 from the air duct is guided by the air guide groove 60 and flows into the interior of the drum 3. Preferably, in this embodiment, the joint 66 is provided above the annular window gasket 65 and extends in the radial direction of the door body 6.

[0088] like Figure 1 As shown, in this embodiment, an openable and closable drum door 7 is installed at the drum opening 301. Drum door 7 is spaced apart from the air guide groove 60 provided on the door body 6 to ensure a sufficient safety gap between the drum door 7 and the door body 6 during the rotation of the drum 3 to prevent collision between the two. Thus, during operation of the laundry processing device, the drum door 7 engages the drum opening 301 to effectively seal it. Preferably, in this embodiment of the present invention, the drum 3 is configured to form a sealed water container when the drum door 7 is closed and the washing cycle is executed.

[0089] like Figure 1As shown, in this embodiment, the drum door 7 is provided with a ventilation module 5 that connects the two sides, and the air outlet 62 of the air guide groove 60 is arranged toward the ventilation module 5;

[0090] Preferably, the ventilation module 5 can be any ventilation structure in the prior art that can achieve the effect of air exchange between the inside and outside of the drum, for example Figure 1 As shown, the ventilation module 5 described in one of the above embodiments.

[0091] Preferably, in this embodiment, a ventilation module 5 is provided at the center of the drum door 7, which protrudes toward the door body 6. The ventilation module 5 extends from the air outlet 62 into the interior of the air guide groove 60 and maintains a distance from the inner wall of the air guide groove 60 to ensure that there is a safe distance between the ventilation module 5 and the air guide groove 60 during the operation of the drum 3, so as to effectively prevent the occurrence of problems such as mutual collision between the two.

[0092] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention.
