Description

Technical Field

[0001] This invention relates to the field of ambient temperature dehumidification technology, and more particularly to a drying device for washing machines. Background Technology

[0002] Washer-dryers on the market are mainly divided into heat pump type and condenser type. Condenser washer-dryers generally dry clothes by introducing cold water into the condenser duct, exchanging heat with the hot humid steam, condensing the water vapor into water droplets, and then discharging it outside the washing machine. Heat pump washer-dryers dry clothes by exchanging heat through an evaporator and condenser to condense the hot humid steam into water droplets and then discharge it outside the washing machine.

[0003] These two types of washer-dryers differ in their drying principles, but both aim to condense humid steam into water droplets by raising the temperature in different ways, thus drying the clothes. However, regardless of the method, the drying stage requires raising the temperature inside the drum, which may cause some damage to the clothing fibers. Especially with condenser dryers, the highest temperature inside the drum during drying can reach 80-90℃, and high temperatures can damage clothing fibers, particularly delicate fabrics like silk and wool. The deformation and damage caused by high temperatures are irreversible.

[0004] Therefore, a new type of washer-dryer is needed to improve dehumidification. Summary of the Invention

[0005] To address the aforementioned technical problems, embodiments of the present invention provide a drying device for a washing machine, which can dehumidify clothes in the washing machine at room temperature and prevent damage to the clothes.

[0006] In a first aspect, embodiments of the present invention disclose a drying device for a washing machine. The washing machine includes an inner washing drum and an outer washing drum, the outer washing drum including a front washing drum and a rear washing drum, and the drying device including: a fan, the air inlet pipe of the fan being connected to the upper part of the front washing drum; and a drying device disposed on an exhaust pipe at the upper part of the rear washing drum, having a drying chamber therein, one end of the drying chamber being connected to the rear washing drum through the exhaust pipe, and the other end being connected to the air outlet pipe of the fan to achieve the circulation of drying air in the front washing drum, the inner washing drum, the rear washing drum, and the drying device; wherein, a room temperature dehumidifier is provided in the drying chamber to dry the humid air passing through it at room temperature.

[0007] Furthermore, the drying device also includes a housing and a rotating support mechanism. A vent is provided on one side of the housing to connect the exhaust pipe and the drying chamber; the rotating support mechanism is mounted inside the drying chamber to support the ambient temperature dehumidifier.

[0008] Furthermore, the rotating support mechanism is a rotating support frame, which includes a first support frame, a second support frame, and a rotating shaft connecting the first support frame and the second support frame, wherein the rotating shaft separates the first support frame and the second support frame.

[0009] Furthermore, the drying device also includes a mesh screen and an outer cover. The mesh screen is disposed on the rotating support frame and is used to wrap the ambient temperature dehumidifier; the outer cover wraps the rotating support frame and the mesh screen to form a placement space for the ambient temperature dehumidifier.

[0010] Furthermore, the drying device also includes a power unit, which is located on one side of the rotating shaft and is used to drive the entire rotating support frame to rotate by rotating the rotating shaft.

[0011] Furthermore, the ambient temperature dehumidifier occupies 60%-80% of the volume of the drying chamber.

[0012] Furthermore, the drying device also includes a heating plate, which is disposed at the bottom of the drying chamber and is used to further dehumidify the ambient temperature dehumidifier.

[0013] Furthermore, the heating plate is a semiconductor heating plate, and the semiconductor heating plate adopts a mosquito coil-shaped spiral electric heating coil to improve heating efficiency.

[0014] Furthermore, the drying device also includes a humidity sensor, which is disposed inside the drying chamber and is used to measure the humidity of the ambient temperature dehumidifier.

[0015] Furthermore, the drying device also includes a normal temperature dehumidifier drain pipe, which connects the bottom of the drying chamber to the drain outlet of the washing machine to drain the moisture in the drying chamber.

[0016] Furthermore, the ambient temperature dehumidifier is made of zeolite.

[0017] By adopting the above technical solution, the present invention has at least the following beneficial effects:

[0018] The drying equipment provided by this invention achieves low-temperature drying of clothes by using a room-temperature dehumidifier, such as a novel material zeolite, and employing simple control logic. This results in efficient and energy-saving drying of clothes, avoids damage to clothes caused by high temperatures, reduces problems such as deformation and fading, and extends the service life of clothes.

[0019] This invention eliminates the need for a continuous flow of large amounts of condensate during the drying stage, avoiding water waste and making it more environmentally friendly and energy-efficient. Furthermore, the elimination of evaporators and condensers simplifies the machine structure, reduces overall cost, and improves energy efficiency.

[0020] This invention eliminates the rear air duct, saving depth space and reducing the overall machine depth, resulting in an ultra-thin design suitable for various home environments. The slim design makes the machine more aesthetically pleasing, occupies less space, and facilitates user installation and use.

[0021] Compared to placing zeolite in the air duct space, this invention utilizes the large area of ​​the washing drum for dehumidification. The drying efficiency is improved, and the control logic is simplified. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to specific examples and the accompanying drawings.

[0040] It should be noted that all uses of "first" and "second" in the embodiments of the present invention are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of the present invention. Subsequent embodiments will not explain this in detail.

[0041] like Figures 1-8 As shown, an embodiment of the present invention discloses a drying device for a washing machine. The washing machine includes an inner washing drum and an outer washing drum. The outer washing drum includes a front washing drum 2 and a rear washing drum 3. The drying device includes a fan 1, the air inlet pipe of which is connected to the upper part of the front washing drum 2; and a drying device 4, which is disposed on an exhaust pipe 31 at the upper part of the rear washing drum 3. A drying chamber 41 is provided inside the drying chamber 41. One end of the drying chamber 41 is connected to the rear washing drum 3 through the exhaust pipe 31, and the other end is connected to the air outlet pipe 12 of the fan 1 to realize the circulation of drying air in the front washing drum 2, the inner washing drum, the rear washing drum 3, and the drying device 4. The drying chamber 41 is also provided with a room temperature dehumidifier 42 to dry the humid gas passing through it at room temperature.

[0042] Specifically, existing washing machines have a washing drum consisting of an inner drum and an outer drum. The inner drum has a clothes-containing cavity for washing clothes. The outer drum includes a front drum 2 and a rear drum 3. These two sections can be used for ease of description, with the part near the air inlet of the fan 1 being the front drum 2 and the other part being the rear drum 3. Alternatively, the outer drum can be divided into two parts using a mesh, with the front drum 2 connected to the air inlet of the fan 1 and the other part being the rear drum 3. The air inlet pipe of the fan 1 connects to the upper part of the front drum 2. The drying device 4 is located on the exhaust pipe 31 at the top of the rear drum 3. A detergent dispenser 5 is also located at the top of both the front drum 2 and the rear drum 3 to supply detergent to the washing machine. The front drum 2 is a steel drum visible when the washing machine door is opened, and the rear drum 3 is a plastic component that encloses the front drum 2. The front washing drum 2 and the rear washing drum 3 are fixed together by screws, allowing washing water to accumulate in the gap between them. During drainage, a drain pump installed at the bottom of the rear washing drum 3 is activated. The bottoms of the front washing drum 2 and the rear washing drum 3 are connected. In this application, the fan 1 has an inlet pipe 11 and an outlet pipe 12. The inlet pipe 11 connects to the air inlet at the top of the front washing drum 2. Gas enters the front washing drum 2 through the inlet and flows into the rear washing drum 3 from the bottom, then flows from the bottom of the rear washing drum 3 to the top and enters the drying device 4 for drying. The dried gas then enters the fan 1 again through the outlet pipe 12 for a new cycle. This drying equipment dries clothes 7 at room temperature without heating and fully utilizes the large space of the rear washing drum 3 for dehumidification, resulting in better dehumidification.

[0043] Preferably, the ambient temperature dehumidifier 42 can be zeolite.

[0044] Zeolite is a mature new material. It possesses high hygroscopicity, can be reused repeatedly over a long period, and can be repeatedly dried after absorbing moisture. Zeolite is a natural mineral with a porous structure, containing numerous micropores and mesopores. These pores can absorb large amounts of moisture, thus exhibiting high hygroscopic capacity. Furthermore, zeolite has good thermal and chemical stability, maintaining structural stability at high temperatures without decomposition or deterioration, allowing for repeated use over a long period. Utilizing zeolite's superior hygroscopic properties, clothing can be dried at room temperature. Room temperature drying avoids damage to clothing from high temperatures, reducing problems such as deformation and fading.

[0045] like Figures 1 to 7As shown, in a preferred embodiment of the present invention, the drying device 4 further includes: a housing 43 and a rotating support mechanism 44. A vent hole is provided on one side of the housing 43 to connect the exhaust pipe 31 and the drying chamber 41 through the vent hole. The rotating support mechanism 44 is mounted in the drying chamber 41 to support the ambient temperature dehumidifier 42.

[0046] Specifically, the housing 43 can be used to provide a housing space for the ambient temperature dehumidifier 42. This housing space is, for example, a drying chamber 41. In order to facilitate communication with the exhaust pipe 31, the housing 43 has a vent on the side that contacts the exhaust pipe 31, through which the exhaust pipe 31 and the drying chamber 41 are connected.

[0047] To increase the working area of ​​the ambient temperature dehumidifier 42, it needs to be mounted to increase the contact area with moisture. The rotating support mechanism 44 is designed for this purpose.

[0048] Preferably, the rotating support mechanism 44 can be equipped with three support feet 441 at the bottom to suspend it in the drying chamber 41, thereby providing more space for the ambient temperature dehumidifier 42.

[0049] like Figures 5 to 7 As shown, in a preferred embodiment of the present invention, the rotating support mechanism 44 includes a first support frame 442, a second support frame 443, and a rotating shaft 444 connected between the first support frame 442 and the second support frame 443, wherein the rotating shaft 444 separates the first support frame 442 and the second support frame 443.

[0050] Specifically, both the first support frame 442 and the second support frame 443 are frame-shaped structures, which can be constructed by welding stainless steel pipes. The first support frame 442 is preferably a circular frame fixed to the rotating shaft 444 by support rods. The support rods are symmetrically arranged along the circular frame. The number of support rods is determined by achieving a good supporting effect, for example, six rods. The shape of the second support frame 443 can be the same as or different from that of the first support frame 442. The first support frame 442 and the second support frame 443 can be symmetrically arranged with the rotating shaft 444 as the center of rotation. Being separated by the rotating shaft 444 provides sufficient space for the ambient temperature dehumidifier 42, such as zeolite, to improve the dehumidification effect.

[0051] like Figures 5 to 7 As shown, in a preferred embodiment of the present invention, the drying device 4 further includes: a mesh 45 and an outer cover 46, the mesh 45 being disposed on the rotating support mechanism 44 for wrapping the ambient temperature dehumidifier 42; and the outer cover 46 wrapping the rotating support mechanism 44 and the mesh 45 to form a placement space for the ambient temperature dehumidifier 42.

[0052] Specifically, the mesh 45 is supported by a support rod to create a space to accommodate it. Since the mesh 45 is flexible and cannot be directly fixed to the washing drum 3, an outer cover 46 is added around the mesh 45 and the support rod. This outer cover 46 is preferably a plastic cover, for example, made of nylon material, which has good strength and high rigidity. The plastic cover is fixed to the exhaust port above the bottom of the outer drum 3 of the washing drum 3 by screws using three brackets.

[0053] like Figures 5 to 7 As shown, in a preferred embodiment of the present invention, the drying device 4 further includes a power device 47, which is disposed on one side of the rotating shaft 444 and is used to drive the entire rotating support mechanism 44 to rotate by rotating the rotating shaft 444.

[0054] Specifically, the power unit 47 is preferably a small asynchronous motor, which can drive the rotating shaft 444 to rotate. A room-temperature dehumidifier 42, for example, zeolite wrapped in a mesh 45, is placed in the space formed by the support frame 44. Under centrifugal force, water is removed and spun dry. Water droplets roll down the inner wall of the drying chamber 41, enter the inner and outer drum interlayer from the bottom of the washing drum 3, and are discharged through the washing machine drain pipe 6.

[0055] In a preferred embodiment of the present invention, the ambient temperature dehumidifier 42 occupies 60%-80% of the volume of the drying chamber 41.

[0056] Specifically, in order to improve the dehumidification effect, the amount of zeolite in the room temperature dehumidifier 42 should be as large as possible. However, since the space of the drying chamber 41 is limited, if it is too large, it will reduce the contact area and affect the dehumidification effect. Therefore, it is preferable that the volume of the zeolite drying chamber 41 is 60%-80%.

[0057] like Figure 2 and Figure 8 As shown, in a preferred embodiment of the present invention, the drying device 4 further includes a heater 48, which is a semiconductor heating plate and is disposed at the bottom of the drying chamber 41 for further dehumidifying the ambient temperature dehumidifier 42.

[0058] Specifically, to further improve the dryness of zeolite, its characteristic is utilized: after absorbing moisture, zeolite can be dried by heating, thereby restoring its moisture-absorbing capacity. When the moisture-absorbing zeolite is heated to a certain temperature, the water molecules in the pores evaporate and escape. Therefore, the semiconductor heating plate at the bottom of the drying chamber 41 starts to heat up rapidly, which can expel the small water molecules between the zeolite molecules, accelerating the drying of the zeolite. The dried zeolite regains its extremely high moisture-absorbing capacity, allowing it to continue drying the clothes 7. Through heating and regeneration, zeolite can restore its moisture-absorbing capacity, enabling long-term and repeated use, thus reducing operating costs.

[0059] Because the semiconductor heating plate does not directly contact the inner and outer walls of the drum, and the size of the exhaust port (connected to the exhaust pipe) is very small relative to the bottom area of ​​the entire washing drum 3, the temperature rise of the semiconductor heating plate has a negligible impact on the temperature of the clothes 7 inside the drum. The clothes 7 inside the drum can still maintain a relatively low temperature, achieving room temperature drying without damaging the fibers of the clothes 7.

[0060] like Figure 2 and Figure 8 As shown, in a preferred embodiment of the present invention, the drying device 4 further includes a heater 48, which is a mosquito coil-type spiral electric heating coil and is disposed at the bottom of the drying chamber 41 for further dehumidifying the ambient temperature dehumidifier 42.

[0061] Specifically, a mosquito coil-shaped spiral electric heating coil is used as an alternative to a semiconductor heating plate. Compared to a semiconductor heating plate, it heats up faster. Its "mosquito coil" shape, such as a spiraling, ascending design, fully utilizes the space at the bottom of the cavity, improving heating efficiency. Since the electric heating temperature is higher than that of a semiconductor heating plate, the drying cavity 41 needs to be replaced with a heat-resistant metal material such as cast iron. The mosquito coil-shaped spiral electric heating coil preferably includes an electric heating channel 481 and electric heating branch channels 482. The electric heating channel 481 is a multi-coil concentric arrangement; the number of coils is not specifically limited but is determined by achieving the best effect. Multiple electric heating branch channels 482 can be present, evenly distributed around the outer periphery of the mosquito coil-shaped spiral electric heating coil.

[0062] Thus, this invention achieves the drying of zeolite using centrifugal force combined with a heating mechanism, greatly improving the drying efficiency of zeolite.

[0063] In a preferred embodiment of the present invention, the drying device 4 further includes a humidity sensor disposed in the drying chamber 41 for measuring the humidity of the ambient temperature dehumidifier 42.

[0064] Specifically, the dehumidifier 42 at room temperature can be, for example, zeolite. After the washing machine has been running for a long time, the zeolite absorbs enough moisture, and its desiccation capacity decreases. A humidity sensor is installed on the bracket of the drying chamber 41 to detect the dryness of the zeolite. The humidity sensor is inserted into the zeolite to detect its humidity in real time. When the detected value exceeds the set value, it means that the drying capacity of the zeolite has dropped to the minimum. At this time, the zeolite needs to be dried, such as by spin-drying, to maintain its dehumidification efficiency.

[0065] like Figure 1 , Figures 3 to 4 As shown, in a preferred embodiment of the present invention, the drying device 4 further includes a room temperature dehumidifier drain pipe 49, which connects the bottom of the drying chamber 41 to the drain outlet of the washing machine to drain the moisture in the drying chamber 41.

[0066] Specifically, the normal temperature dehumidifier drain pipe 49 is a rubber pipe that can allow water in the drying chamber 41 to enter the inner and outer drum interlayer from the bottom of the washing drum 3 and be discharged through the washing machine drain pipe 6.

[0067] In the entire process, the air inlet pipe 11 of the fan 1 introduces gas into the top of the pre-washing drum 2, flows to the bottom of the pre-washing drum 2, then flows from the bottom of the pre-washing drum 2 into the bottom of the post-washing drum 3, and flows along the inner cavity of the post-washing drum 3 to the top, and then enters the drying device 4 for drying using zeolite. The dried gas then enters the fan 1 again through the air outlet pipe 12 for a new cycle. After this cycle is repeated several times, the moisture absorption capacity of the zeolite decreases compared to the drying stage after it is fully saturated with water. In order to ensure that the drying efficiency is maintained at a high level, the zeolite that has absorbed water needs to be dried. Drying method: The drying chamber 41 is equipped with a humidity sensor. After running for a period of time, the dehumidification capacity of the zeolite decreases after it absorbs a large amount of moisture. When the humidity sensor detects that the humidity of the zeolite reaches a certain value, it indicates that the zeolite needs to be dried. Drying method: The motor connected to the rotating shaft is started, and centrifugal force shakes off the adsorbed water, which rolls off the inner wall of the circular cavity. Furthermore, the heater 48 rapidly heats up, and through heating and regeneration, the zeolite can regain its moisture absorption capacity, enabling long-term and repeated use and reducing operating costs. Water droplets thrown against the inner wall by centrifugal force accumulate at the bottom of the chamber, flow along the water pipe to the bottom of the rear cylinder, and are drained away through the drain pipe. Until the humidity sensor detects that the humidity has reached the standard, the fan 1 starts, and the zeolite continues to absorb moisture and dry.

[0068] This invention provides a drying device for washing machines that changes the high-temperature drying technology of existing condenser and heat pump washer-dryers. It employs a low-temperature drying technology to care for clothes, aiming to achieve efficient and energy-saving drying of clothes through relatively simple control logic and novel materials, such as zeolite. This technology not only achieves low-temperature drying but also effectively protects clothes, preventing damage from high temperatures, reducing deformation and fading, and extending the lifespan of the clothes. Furthermore, a humidity sensor can quickly determine the dryness level of the clothes.

[0069] This invention eliminates the need for a continuous flow of large amounts of condensate during the drying stage, avoiding water waste and making it more environmentally friendly and energy-efficient. Furthermore, the elimination of evaporators and condensers simplifies the machine structure, reduces overall cost, and improves energy efficiency.

[0070] This invention eliminates the rear air duct, saving depth space and reducing the overall machine depth, resulting in an ultra-thin design suitable for various home environments. The slim design makes the machine more aesthetically pleasing, occupies less space, and facilitates user installation and use.

[0071] Compared to placing zeolite in the air duct space, this invention utilizes the three large areas of the washing drum for dehumidification. The drying efficiency is improved, and the control logic is simplified.
