Description

Technical Field

[0001] This invention belongs to the field of washing and care technology, specifically providing a washing and drying integrated device. Background Technology

[0002] Washer-dryer combos are garment processing devices that can wash, rinse, dehydrate, and dry clothes. Some washer-dryer combos also have additional functions such as air washing, disinfection, sterilization, and fragrance enhancement.

[0003] Taking a drum washer-dryer combo as an example, existing drum washer-dryers consist of an outer drum and an inner drum. During washing, a certain amount of water is first injected into the outer drum, and then the inner drum tumbles the clothes to achieve washing. It is designed to mimic the principle of beating clothes with a stick. After washing the clothes, the outer drum and the window gasket connected to the outer drum are damp, meaning there is residual water on their inner walls. With prolonged use, bacteria can easily grow. Simply opening the door glass to allow the outer drum and window gasket to dry naturally has very limited effect, and the window gasket contains folds, which is very unfavorable for the dissipation of moisture. When the user uses the drum washer-dryer combo a second time, the bacteria and dirt on the inner wall of the outer drum and the window gasket can easily cause secondary contamination of the clothes, seriously affecting the washing effect and resulting in a poor user experience. Of course, drum washer-dryers also have a drying system that can dry the residual water in the outer drum and the window seal after washing clothes. However, the drying system of drum washer-dryers uses an internal circulation method, which means that water vapor still circulates between the drying channel and the outer drum. Moreover, the dehumidification of the washer-dryer mainly relies on the condenser of the drying system. This means that if the residual water in the outer drum and the window seal is to be further removed after the drying cycle, all the devices in the drying system need to be running for a very long time. This will seriously increase the energy consumption of the washer-dryer and is very detrimental to energy conservation.

[0004] Therefore, there is a need in the field for a new washer-dryer combo to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems in the prior art, namely the high energy consumption and poor effectiveness of existing washer-dryer units in removing residual water from the outer drum, this invention provides an integrated washer-dryer unit. The unit includes a drum assembly, a drying channel, an air guide assembly, and a fan. The fan is disposed within the drying channel, which is connected to the drum assembly to form a circulating air path. A bypass ventilation branch connecting the drying channel to the outside is provided. The air guide assembly includes a housing disposed at the connection point between the drying channel and the ventilation branch, and at least a portion of an air guide member disposed within the housing. The housing has an air inlet and an air outlet connected to the drying channel, as well as a vent connected to the ventilation branch. The air guide member is configured to selectively close the vent.

[0006] In the preferred embodiment of the above-mentioned washer-dryer integrated equipment, the air guide component includes a drive motor and an air guide plate. The drive motor is disposed outside the housing, and the air guide plate is disposed inside the housing. The output shaft of the drive motor is connected to the air guide plate and can drive the air guide plate to rotate so as to selectively close the vent.

[0007] In the preferred technical solution of the above-mentioned washer-dryer integrated equipment, the ventilation area of ​​the vent is larger than the air inlet area.

[0008] In the preferred embodiment of the above-mentioned washer-dryer, the fan is located on the upstream side of the housing along the airflow direction in the drying channel.

[0009] In the preferred embodiment of the above-mentioned washer-dryer integrated equipment, the air inlet is located on the top side of the housing, the air outlet is located on the bottom side of the housing, and the ventilation opening is located on the front side of the housing.

[0010] In the preferred embodiment of the above-mentioned washer-dryer, an opening is provided on the front panel of the washer-dryer, and the ventilation branch is connected to the opening.

[0011] In the preferred embodiment of the above-mentioned washer-dryer integrated equipment, the drum assembly includes a connected outer drum and a window gasket, the outlet of the drying channel is connected to the window gasket, and the inlet of the drying channel is connected to the outer drum.

[0012] In the preferred embodiment of the above-mentioned washer-dryer, the outlet of the drying channel is connected to the top of the window gasket.

[0013] In the preferred embodiment of the above-mentioned washer-dryer, the inlet of the drying channel is connected to the rear of the outer cylinder.

[0014] In the preferred embodiment of the above-mentioned washer-dryer, the outlet of the drying channel is tangentially arranged on the window gasket.

[0015] In the preferred embodiment of the present invention, when the air guide component closes the vent, the drying channel is isolated from the outside, allowing the washer-dryer to dry clothes normally. When the air guide component opens the vent, the drying channel is connected to the outside through a ventilation branch, allowing outside air to enter the drying channel and dry the inside of the drum assembly. The humid air inside the drum assembly can also be discharged to the outside, which is conducive to the rapid drying and discharge of moisture and prevents bacteria from growing inside the drum assembly due to residual water. At the same time, the air guide component not only prevents dust from entering the drum assembly, but also prevents foam from overflowing outside the washer-dryer during the washing process. During the drying process, only the fan of the drying system needs to be turned on; the dehumidification device and heating device of the drying system do not need to be operated, thus avoiding excessive energy consumption. This not only achieves the drying of the drum assembly but also improves the drying efficiency and is energy-saving.

[0016] Furthermore, by driving the air guide plate to rotate via a drive motor, a rotation drive method is adopted. This setting can minimize the space occupied by the air guide components, which is more conducive to the overall spatial structure layout design of the washing and drying integrated equipment. Moreover, the structure is simple and easy to manufacture.

[0017] Furthermore, the ventilation area of ​​the vent is larger than the air intake area of ​​the air inlet. This means that when the washer-dryer is performing the drying process, the vent can not only expel humid air, but also make it easier for outside air to enter the drum assembly, which helps to maintain the balance of internal and external air pressure.

[0018] Furthermore, the outlet of the drying channel is connected to the window gasket, and the inlet of the drying channel is connected to the outer drum, allowing outside air to enter through the window gasket to dry it first, and then dry the outer drum. Finally, the humid air is discharged through the ventilation branch, so that the outer drum and the window gasket can be dried at the same time. This prevents the clothes from developing odors when the user forgets to take them out, and also prevents secondary pollution when the user washes the clothes a second time, thus affecting the user experience.

[0019] Furthermore, the outlet of the drying channel is tangentially positioned on the window gasket to ensure that outside air enters the window gasket tangentially, thereby forming a circular airflow within the window gasket. This facilitates thorough drying of the window gasket without any dead angles and improves the drying effect. Attached Figure Description

[0020] The preferred embodiment of the present invention will now be described with reference to the accompanying drawings and in conjunction with the drum-type washer-dryer combo machine, in which:

[0021] Figure 1This is a schematic diagram of the structure of the drum-type washer-dryer of the present invention. Figure 1 ;

[0022] Figure 2 This is a schematic diagram of the structure of the drum-type washer-dryer of the present invention. Figure 2 ;

[0023] Figure 3 This is a schematic diagram of the air guide assembly of the present invention. Detailed Implementation

[0024] First, those skilled in the art should understand that these embodiments are merely for explaining the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. For example, although the present invention is described in conjunction with a drum-type washer-dryer combo, the technical principles of the present invention are obviously applicable to other types of washer-dryer combos, or multi-layer garment processing equipment, etc. Adjustments or changes to these applications do not constitute a limitation of the present invention and should all be limited within the scope of protection of the present invention.

[0025] It should be noted that in the description of this invention, the terms "middle," "front," "rear," "top," "bottom," "horizontal," "inner," and "outer," etc., which indicate the direction or positional relationship, are based on the direction or positional relationship shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention.

[0026] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "set," "connect," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0027] Based on the problems pointed out in the background art regarding the high energy consumption and poor effect of existing drum-type washer-dryers in removing residual water from the outer drum, this invention provides a drum-type washer-dryer that can dry clothes normally and also air-dry the inside of the drum assembly, preventing bacteria growth due to residual water inside the drum assembly, while also preventing external dust and other substances from entering the drum assembly and preventing foam from overflowing outside the drum-type washer-dryer, thus avoiding excessive energy consumption. It improves drying efficiency while achieving air drying of the drum assembly and is also conducive to energy saving.

[0028] Specifically, such as Figure 1 and 2As shown, the drum washer-dryer of the present invention includes a housing 1 and a drum assembly disposed within the housing 1. The drum assembly includes an inner drum 2, an outer drum 3, and a window gasket 4. The inner drum 2 is rotatably disposed within the outer drum 3. The window gasket 4 connects the opening of the outer drum 3 to the door opening of the housing 1. In a top-opening drum washer-dryer, the outer drum 3 and the inner drum 2 are coaxial and both are arranged laterally. The window gasket 4 connects the upper opening of the outer drum 3 to the door opening at the top of the housing 1. In a front-opening drum washer-dryer, the outer drum 3 and the inner drum 2 are coaxial and both are arranged laterally. The window gasket 4 connects the front opening of the outer drum 3 to the door opening at the front of the housing 1. Figure 1 The diagram shown is a schematic of a front-opening drum washer-dryer combo. Those skilled in the art will understand that the inner drum 2 can be directly driven to rotate by a direct-drive motor, or it can be driven by a belt via a motor. The outer drum 3 holds the washing water, the inner drum 2 tumbles the clothes, and the gasket 4 ensures a seal between the outer drum 3 and the casing 1.

[0029] See also Figure 1 The drum washer-dryer of the present invention also includes a drying system, which includes a drying channel 5 connected to the outer drum 3 and a fan 6 disposed in the drying channel 5. The drying channel 5 and the outer drum 3 together form a circulating air path. A dehumidifying device and a heating device (not shown in the figure) are also disposed in the drying channel 5. Along the air flow direction in the drying channel 5, the dehumidifying device is disposed upstream of the heating device. When the drum washer-dryer performs the drying program, the fan 6 is started, so that the air circulates between the drying channel 5 and the outer drum 3. Specifically, the humid air in the outer drum 3 enters the drying channel 5 and is first dehumidified by the dehumidifying device, so that the humid air becomes relatively dry and low temperature air. Then, the relatively dry and low temperature air is heated by the heating device, so that the relatively dry and low temperature air becomes high temperature dry air. Finally, it circulates back into the outer drum 3, and the high temperature dry air continues to dry the clothes. The air that passes through the clothes becomes humid air again and enters the drying channel 5.

[0030] In the above, the drying system can be a heat pump drying system, that is, the dehumidification device is an evaporator and the heating device is a condenser. In addition, the heat pump drying system also has a compressor. The evaporator, condenser and compressor are connected end to end to form a refrigerant circulation loop. The evaporator can dehumidify the air and the condenser can heat the air. When the drum washer-dryer is executing the drying program, the fan 6, evaporator, condenser and compressor work together to complete the drying operation of the clothes. The compressor is preferably located outside the drying channel 5 to avoid the water vapor in the air from affecting the operation of the compressor. Of course, the drying system can also be a condenser drying system, that is, the dehumidification device is a condenser fin, and the heating device is a heating tube or electric heating wire, etc. The condenser fin can dehumidify the air, and the heating tube or electric heating wire can heat the air. When the drum-type washer-dryer is executing the drying program, taking the electric heating tube as an example, the fan 6, the condenser fin and the electric heating tube work together to complete the drying operation of the clothes. The power supply end of the electric heating tube is preferably located outside the drying channel 5 to avoid the water vapor in the drying channel 5 from affecting the operation of the electric heating tube and causing safety hazards.

[0031] In this invention, a condensate collection device can be installed below the dehumidifier, such as a condensate trough formed in the housing 1 or the base of the housing 1, or a separate condensate collection box. The fan 6 can be located upstream of the dehumidifier, between the dehumidifier and the heating device, or downstream of the heating device. Such adjustments or changes to the specific location of the fan 6 do not constitute a limitation of this invention and should be limited to the scope of protection of this invention.

[0032] It should be noted that the conventional program of a drum washer-dryer includes washing, rinsing, spin-drying, draining, and drying. In some drum washer-dryers, the spin-drying process may be omitted, or the drying process may be omitted because the material of the clothes is not suitable for drying. Such adjustments or changes to the conventional program of the drum washer-dryer do not constitute a limitation of the present invention and should be limited to the protection scope of the present invention. During the washing process, a large amount of foam will be generated due to the presence of detergent / laundry powder. After the draining process, there will be residual water on the inner surface of the outer drum 3 and the inner surface of the window gasket 4.

[0033] like Figure 1 and 3As shown, the drum-type washer-dryer of the present invention also includes an air guide assembly 7. The drying channel 5 is provided with a ventilation branch 8 that communicates with the outside. The air guide assembly 7 includes a housing 71 disposed at the connection between the drying channel 5 and the ventilation branch 8 and an air guide member disposed in at least part of the housing 71. The housing 71 has an air inlet 71a and an air outlet 71b that communicate with the drying channel 5 and a ventilation opening 71c that communicates with the ventilation branch 8. The air guide member is configured to selectively close the ventilation opening 71c. When the drum washer-dryer is running the drying program, the air guide component closes the vent 71c, meaning that only the air inlet 71a and air outlet 71b of the housing 71 allow air to flow. After the fan 6 is started, the air in the drying channel 5 enters the housing 71 through the air inlet 71a and then returns to the drying channel 5 through the air outlet 71b. Since the vent 71c of the housing 71 is closed by the air guide component, the air in the drying channel 5 will not flow to the ventilation branch 8, meaning that the drying channel 5 is not connected to the outside, thus preventing the leakage of drying gas and affecting the normal drying process. When the drum washer-dryer is running the air-drying program, the air guide component opens the vent 71c, connecting the drying channel 5 with the ventilation branch 8. That is, the air inlet 71a, air outlet 71b, and vent 71c of the housing 71 are all connected to each other, allowing airflow. The drying channel 5 is connected to the outside through the ventilation branch 8. After the fan 6 is started, the air in the drying channel 5 enters the housing 71 through the air inlet 71a. Then, part of the air in the housing 71 is discharged to the outside through the vent 71c and the ventilation branch 8, while the other part of the air returns to the drying channel 5 through the air outlet 71b. In order to achieve air pressure balance inside and outside the outer drum 3, outside air also enters the drying channel 5 through the ventilation branch 8 and the vent 71c, thereby achieving air exchange. In this way, outside air can also exchange with the air inside the outer drum 3, achieving the purpose of air drying. In a preferred embodiment, the ventilation area of ​​the vent 71c is larger than the air inlet area of ​​the air inlet 71a. This reduces convection at the vent 71c, making air exchange at the vent 71c more efficient. Figure 3In the structure shown, from the perspective of air flow, the air inlet 71a corresponds to the central area of ​​the vent 71c, while the non-central area of ​​the vent 71c (i.e., the outer area surrounding the central area) does not correspond to the air inlet 71a. When air enters the housing 71 through the air inlet 71a, a portion of the air inside the housing 71 flows out from the central area of ​​the vent 71c, i.e., into the ventilation branch 8, and then is discharged to the outside. Outside air enters the housing 71 from the outer area surrounding the central area through the ventilation branch 8, and then flows back into the drying channel 5 from the air outlet 71b of the housing 71 together with another portion of the air inside the housing 71, thereby achieving air exchange. Through this arrangement, the air outlet of the vent 71c is in the central area, and the air inlet is in the outer area surrounding the central area. The air inlet and outlet hardly form convection, ensuring smooth air exchange. It should be noted that the aforementioned housing 71 can be a separate component, i.e., the housing 71 is fixedly connected to the connection between the drying channel 5 and the ventilation branch 8. Alternatively, the housing 71 can also be a part of the drying channel 5 or a part of the drying channel 5 and the ventilation branch 8, i.e., the housing 71 can be formed by the inner wall of the drying channel 5 and the inner wall of the ventilation branch 8. Such adjustments or changes to the specific structure of the housing 71 do not constitute a limitation of the present invention and should be limited to the protection scope of the present invention. In the present invention, when the drum-type washer-dryer performs the air-drying program, only the fan 6 of the drying system needs to be started to realize the air-drying process. The dehumidification device and heating device of the drying system do not need to work together to complete the air-drying of the inside of the drum assembly.

[0034] Preferably, the air guiding component includes a drive motor 72 and an air guiding plate 73. The drive motor 72 is disposed outside the housing 71, and the air guiding plate 73 is disposed inside the housing 71. The output shaft of the drive motor 72 is connected to the air guiding plate 73 and can drive the air guiding plate 73 to rotate so as to selectively close the vent 71c. The drive motor 72 can be directly connected to the air guiding plate 73, or it can be connected to the air guiding plate 73 through a gear pair structure. For example, the drive motor 72 is first connected to a small gear, and then the small gear meshes with a large gear. The large gear is connected to the air guiding plate 73. The difference in diameter between the small gear and the large gear gives the gear pair a speed reduction effect, thereby achieving stable rotation of the air guiding plate 73. The rotation axis of the air guide plate 73 can be located at the edge of the vent 71c. In this case, the drive motor 72 is directly or indirectly connected to the edge of the air guide plate 73, and the vent 71c is opened or closed by the rotation of the air guide plate 73. Of course, the rotation axis of the air guide plate 73 can also be located at the middle of the vent 71c. In this case, the drive motor 72 is directly or indirectly connected to the middle of the air guide plate 73, and the vent 71c is opened or closed by the rotation of the air guide plate 73. That is, when the air guide plate 73 is opened, a part of the air guide plate 73 opens a part of the vent 71c, and the other part of the air guide plate 73 opens another part of the vent 71c, thereby achieving the complete opening of the vent 71c. The same principle applies when closing. When the air guide plate 73 is closed, a part of the air guide plate 73 closes a part of the vent 71c, and the other part of the air guide plate 73 closes another part of the vent 71c, thereby achieving the complete closure of the vent 71c. More preferably, a sealing gasket is provided on the side of the air guide plate 73 near the vent 71c. When the air guide plate 73 covers the vent 71c, the sealing gasket can seal the vent 71c, preventing external dust from entering the drying channel 5 and also preventing foam from overflowing outside the housing 1 during washing. In other examples, the sealing gasket on the air guide plate 73 can be replaced with a sealing ring that corresponds to the shape of the vent 71c.

[0035] In addition, the air guide plate 73 can also be adjusted manually, that is, the drive motor 72 can be replaced with a crank handle, and the rotation of the air guide plate 73 can be controlled by cranking the crank handle. The drive motor 72 can also be a linear motor. In this case, the air guide plate 73 can be replaced with an air guide plate or air guide block structure, that is, the opening and closing of the vent 71c can be achieved by sliding. Those skilled in the art can flexibly set the structure of the air guide component.

[0036] It should be noted that the positions of the air inlet 71a, air outlet 71b, and vent 71c can be flexibly configured. If the ventilation branch 8 is located on a straight section of the drying channel 5, the air inlet 71a and air outlet 71b are preferably located on opposite sides of the housing 71, and the vent 71c is located on adjacent sides of the air inlet 71a and air outlet 71b. If the ventilation branch 8 is located on a bend in the drying channel 5, the air inlet 71a and air outlet 71b are preferably located on adjacent sides of the housing 71, and the vent 71c is located on either the opposite side of the air inlet 71a or the opposite side of the air outlet 71b. For example, in Figure 3 In the structure shown, the air inlet 71a is located on the top side of the housing 71, the air outlet 71b is located on the bottom side of the housing 71, and the vent 71c is located on the front side of the housing 71. Furthermore, along the air flow direction within the drying channel 5, the fan 6 can be located on the upstream side or the downstream side of the housing 71.

[0037] Preferably, such as Figure 2 As shown, the front panel of the drum-type washer-dryer of the present invention has an opening 1a communicating with the outside. A ventilation branch 8 is connected to the opening 1a, allowing humid air to be discharged to the outside through this opening 1a on the front panel. In other examples, the outlet of the ventilation branch 8 can directly pass through the opening 1a, meaning the opening 1a serves only as the installation port for the ventilation branch 8, and humid air is directly discharged to the outside through the outlet of the ventilation branch 8. When humid air is led to the outside through the opening 1a on the front panel, a decorative cover can be provided on the opening 1a. The decorative cover can be grille-shaped or a concealed structure. In other examples, the opening 1a is not limited to being located on the front panel; it can also be located on the left and right side panels, or even on the control panel or the console with the display screen. Any adjustment or change in the specific location of the opening 1a should be limited to the scope of protection of this invention.

[0038] Preferably, the outlet of the drying channel 5 is connected to the window pad 4, and the inlet of the drying channel 5 is connected to the outer drum 3. Further, the outlet of the drying channel 5 is preferably connected to the top of the window pad 4, and the inlet of the drying channel 5 is preferably connected to the rear of the outer drum 3. This ensures effective drying of clothes while also increasing the drying area of ​​the outer drum 3. Furthermore, the outlet of the drying channel 5 is tangentially positioned on the window pad 4. This arrangement allows the air entering the window pad 4 from the drying channel 5 to enter tangentially, forming an annular airflow within the window pad 4, thereby achieving air drying of the window pad 4. The outlet is preferably located in the folds of the window pad 4 to dry these folds. The drying channel 5 can also form multiple branches, for example in… Figure 1The drying channel 5 of the drum washer-dryer shown forms multiple branches at its outlet. The outlets of these branches connect to multiple connecting ports located on the window pad 4. Each branch corresponds to a connecting port. The multiple connecting ports are arranged at equal or unequal intervals along the circumference of the window pad 4. Each connecting port is tangentially positioned on the window pad 4. This tangential positioning means that when viewed from the front of the window pad 4 (i.e., the annular structure of the window pad 4 is visible), all connecting ports are oriented either clockwise or counterclockwise along the circumference of the window pad 4. This allows for the formation of clockwise or counterclockwise annular airflow within the window pad 4, ensuring thorough drying of all parts of the window pad 4 and further improving the drying effect.

[0039] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
