Description

[Technical field]

[0001] The present invention relates to the technical field of household appliances, and in particular to a clothing processing device. [Background technology]

[0002] The clothing treatment equipment proposed in the prior art realizes deodorization, sterilization and other care of clothing by carrying a care device. Taking the electrostatic atomization device as an example, the electrostatic atomization device has a built-in ion generator, which ionizes water molecules in the air to produce atomized particles. The atomized particles enter the air duct and enter the designated area (such as the washing bucket where the clothes are placed) along the air duct to perform deodorization, sterilization and other care operations. In the above care operation, the atomized particles generated inside the electrostatic atomization device are generally released with the help of the airflow sucked from the outside (the release here refers to the process of the atomized particles generated inside the electrostatic atomization device entering the air duct).

[0003] However, in some clothes processing equipment, in order to prevent heat from overflowing during the drying operation, the water tub is not connected to the outside world. If the water tub of this structure is used to implement the above-mentioned care operation, after the clothes processing equipment has been running for a period of time, the air pressure in the water tub and the air duct reaches equilibrium with the outside air pressure, and the air volume in the water tub and the air duct is close to saturation. At this time, it is difficult for the outside air to be inhaled, resulting in insufficient airflow in the electrostatic atomization device, and the electrostatic atomization device releases less atomized particles, resulting in too little atomized particles in the air duct and the washing tub, which reduces the care effect. The present invention studies the above-mentioned problem and proposes a solution. [Summary of the invention]

[0004] An object of the present invention is to provide a clothes processing device which can at least partially solve the above-mentioned technical problems.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] Clothes processing equipment, comprising:

[0007] A water storage tub having a built-in washing tub which is interconnected and rotatable; and

[0008] an air duct equipped with a fan, wherein both ends of the air duct are connected to the water tub, and the operation of the fan forms a circulating airflow in the washing tub and the air duct; and

[0009] An electrostatic atomizing device capable of generating atomized particles has an air inlet connected to the outside space and an air outlet connected to the air duct. The atomized particles generated by the electrostatic atomizing device are sent into the air duct with the help of airflow sucked from the outside and enter the water tub and the washing tub with the circulating airflow to care for the clothes; and

[0010] The exhaust passage is used to connect the water tub to the outside space during the nursing process.

[0011] In the above-mentioned clothing processing equipment, the fan separates the air duct into a positive pressure zone and a negative pressure zone, and the air outlet is connected to the negative pressure zone so that the outside air is sucked into the electrostatic atomization device from the air inlet under the action of negative pressure.

[0012] In the above-mentioned clothing processing equipment, the water tub also has an air inlet and a return air outlet, the fan has an air inlet side and an air outlet side, the air duct includes a return air channel and an air outlet channel, the return air channel connects the air inlet side and the return air outlet to form the negative pressure zone, the air outlet channel connects the air outlet side and the air inlet to form the positive pressure zone, and the air outlet is connected to the return air channel.

[0013] In the above-mentioned clothes treating apparatus, the air inlet is located at the front side of the tub, and the exhaust passage is connected to the rear side of the tub.

[0014] In the above-mentioned clothing processing equipment, an air suction duct is connected between the air outlet and the return air channel, and a non-return structure is provided in the air suction duct to prevent the fluid from flowing back into the electrostatic atomization device, and the non-return structure includes at least one non-return member, and the non-return member has an open state allowing the forward-flowing fluid in the air suction duct to pass through and a closed state preventing the reverse-flowing fluid in the air suction duct from passing through.

[0015] In the above-mentioned clothing processing device, the anti-return structure includes two anti-return parts arranged at intervals and a anti-return cavity surrounded by the two anti-return parts in the suction pipe. When the two anti-return parts are in a closed state, the anti-return cavity is a closed space.

[0016] In the above-mentioned clothes processing device, the anti-return chamber is inclined from low to high in the reverse flow direction.

[0017] In the above-mentioned clothes processing device, the clothes processing device further comprises a detergent box connected to the external space, the water tub is provided with an exhaust port, and the exhaust port is connected to the detergent box through a pipeline to form the exhaust channel.

[0018] In the above-mentioned clothes processing device, the clothes processing device further includes a drain valve, the water tub is provided with a drain port, and the drain port is connected to the drain valve through a pipeline to form the exhaust channel.

[0019] In the above-mentioned clothes processing device, the clothes processing device further includes a control valve for controlling the on-off of the exhaust passage.

[0020] Beneficial effects of the present invention:

[0021] In the clothing treatment device proposed by the present invention, both ends of the air duct equipped with a fan are connected to the water tub, and the action of the fan forms a circulating airflow in the washing tub and the air duct. Compared with the single airflow into the washing tub, the circulating airflow has stronger fluidity in the washing tub, thereby promoting the uniform attachment of the atomized particles to the clothes, and allowing the newly generated atomized particles to be continuously sent into the washing tub with the help of the airflow circulation, thereby maintaining efficient care operations. More importantly, the clothing treatment device is also provided with an exhaust passage, which is used to connect the water tub to the outside space during the care process. More specifically, during the implementation of the care process, part of the air in the water tub is released to the outside through the exhaust passage, and the air duct can continuously inhale the outside air from the air inlet of the electrostatic atomization device. When the outside air passes through the electrostatic atomization device, the atomized particles generated inside the electrostatic atomization device are blown into the air duct, ensuring the release effect of the electrostatic atomization device, so that more atomized particles enter the washing tub during the care process to participate in the deodorization, sterilization and other care operations of the clothes.

[0022] Furthermore, the air duct is divided into a positive pressure zone and a negative pressure zone by the fan, and the air outlet is connected to the negative pressure zone, so that the outside air is sucked into the electrostatic atomization device from the air inlet under the action of negative pressure. Since the air pressure in the negative pressure zone is lower than the normal pressure, the outside air is sucked from the air inlet of the electrostatic atomization device under the action of the pressure difference, and then blown into the negative pressure zone from the air outlet. When the outside air passes through the electrostatic atomization device, it has a higher flow rate and flow, so that more atomized particles can be released into the air duct.

[0023] Furthermore, the water tub also has an air inlet and a return air outlet, the fan has an air inlet side and an air outlet side, the air duct includes a return air channel and an air outlet channel, the return air channel connects the air inlet side and the return air outlet to form the negative pressure area, the air outlet channel connects the air outlet side and the air inlet to form the positive pressure area, and the air outlet connects the return air channel. The side where the fan inhales air when working is the air inlet side, and the air in the return air channel is inhaled by the fan to form a negative pressure area, and the side where the fan blows out air when working is the air outlet side, and the fan blows out air into the air outlet channel to form a positive pressure area in the air outlet channel; the circulating airflow in the air duct is sent into the water tub and the washing tub through the air inlet, and the circulating airflow in the washing tub returns to the air duct through the return air outlet, forming an internal circulation of airflow from the air duct, the water tub to the washing tub.

[0024] Furthermore, the air inlet is located at the front side of the water tub, and the exhaust channel is connected to the rear side of the water tub. The position where the exhaust channel connects to the water tub is far from the air inlet, so as to prevent part of the atomized particles blown in from the air inlet from being directly blown out from the exhaust channel and causing waste.

[0025] Furthermore, an air suction pipe is connected between the air outlet and the return air channel, and a backflow prevention structure is provided in the air suction pipe for preventing the fluid from backflowing into the electrostatic atomization device, and the backflow prevention structure includes at least one backflow prevention member, and the backflow prevention member has an open state that allows the forward-flowing fluid in the air suction pipe to pass through, and a closed state that prevents the reverse-flowing fluid in the air suction pipe from passing through. During the washing process of the clothing processing device, a large amount of foam is generated in the water tub and the washing tub. As the washing tub operates, foam, washing water and other fluids will be squeezed out and flow back into the return air channel through the return air outlet. Since the air outlet is connected to the return air channel, the foam, washing water and other fluids entering the return air channel will threaten the electrostatic atomization device. For example, the reverse-flowing fluid enters the electrostatic atomization device from the air outlet, destroying the atomized particles, and may cause a short circuit failure of the electrostatic atomization device. The setting of the suction pipe extends the distance between the air outlet and the return air channel. When backflow occurs, the reverse path is extended, making it difficult for the backflow fluid to flow to the air outlet. The setting of the anti-return structure enhances the anti-return effect of the suction pipe. When performing nursing operations, the anti-return structure is opened to keep the suction pipe unobstructed, so that the outside air carrying the atomized particles is sucked into the return air channel through the suction pipe.

[0026] Furthermore, the anti-return structure includes two anti-return parts arranged at intervals and an anti-return cavity surrounded by the two anti-return parts in the air suction pipe, and when the two anti-return parts are in a closed state, the anti-return cavity is a closed space. Compared with the conventional arrangement of two anti-return parts, the present solution further forms an anti-return cavity between the two anti-return parts, and when the two anti-return parts are in a closed state, the anti-return cavity is a closed space. In the reverse flow direction of the air suction pipe, the first anti-return part plays a first anti-return role. If the reverse flow fluid enters the anti-return cavity through the first anti-return part, since the anti-return cavity is a closed space, the air pressure in the anti-return cavity will increase with the entry of the reverse flow fluid, and the reverse flow fluid will be prevented from continuing to move forward in the reverse flow direction. The anti-return cavity plays a second anti-return role. If the reverse flow fluid reaches the second anti-return part, the second anti-return part plays a third anti-return role. The above triple anti-return greatly improves the anti-return ability of the anti-return structure.

[0027] Furthermore, the anti-return cavity is inclined from low to high in the reverse flow direction. On the one hand, the climbing resistance of the reverse flow fluid is increased, and the anti-return effect is better. On the other hand, the anti-return cavity is inclined from high to low in the downstream direction, which reduces the flow resistance of the downstream fluid, such as the outside air carrying the atomized particles enters the return air channel more smoothly through the suction pipe.

[0028] Furthermore, the laundry processing device further comprises a detergent box connected to the external space, the water tub is provided with an exhaust port, the exhaust port is connected to the detergent box through a pipeline to form the exhaust channel. The detergent box is an existing component of the laundry processing device, and the exhaust channel thus formed is more cost-effective.

[0029] Furthermore, the clothing treatment device further comprises a drain valve, the water tub is provided with a drain port, the drain port is connected to the drain valve through a pipeline to form the exhaust channel. The drain valve is an existing component of the clothing treatment device, and the exhaust channel thus formed is more cost-effective, and the water tub does not need to have a separate exhaust port for care exhaust.

[0030] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

[0046] The clothing treatment device proposed in the present invention comprises: a water tub having a built-in washing tub which are interconnected and rotatable; and an air duct equipped with a fan, wherein both ends of the air duct are connected to the water tub, and the action of the fan forms a circulating airflow in the washing tub and the air duct; and an electrostatic atomization device capable of generating atomized particles, comprising an air inlet connected to an external space and an air outlet connected to the air duct, wherein the atomized particles generated by the electrostatic atomization device are sent into the air duct with the help of an airflow inhaled from the outside and enter the water tub and the washing tub with the circulating airflow to care for the clothes; and an exhaust passage for connecting the water tub to the external space during the care process.

[0047] According to the above-mentioned clothing processing equipment, during the care process, part of the air in the water tub can be released to the outside through the exhaust channel, and the air duct can continuously inhale the outside air from the air inlet of the electrostatic atomization device. When the outside air passes through the electrostatic atomization device, the atomized particles generated inside the electrostatic atomization device are blown into the air duct to ensure the release effect of the electrostatic atomization device, so that more atomized particles can enter the washing tub during the care process to participate in the deodorization, sterilization and other care operations of the clothes.

[0048] The technical solutions of the embodiments of the present invention are explained and described below in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, not all.

[0052] Reference Figure 1 , 2 In one embodiment of the present invention, a clothes processing device is provided, comprising a water tub 100, a washing tub 200 disposed in the water tub 100, and an air duct 300 disposed outside the water tub 100. Both ends of the air duct 300 are connected to the water tub 100 to form a circulating air path. A fan 400 is disposed on the air duct 300. The fan 400 operates to form a circulating airflow in the washing tub 200 and the air duct 300. Specifically, the water tub 100 is usually suspended in the body of the clothes processing device, and the washing tub 200 is horizontally or rearwardly oriented with its rotation axis to form a circulating airflow. The washing tub 200 is rotatably arranged in the water tub 100 in a manner of being tilted downward in a horizontal direction; the front parts of the water tub 100 and the washing tub 200 both form openings for taking clothes in and out, and the internal spaces of the water tub 100 and the washing tub 200 can be connected through the front opening of the washing tub 200; usually, a through hole connected to the water tub 100 is provided on the barrel wall of the washing tub 200, so the internal spaces of the water tub 100 and the washing tub 200 can be connected through the front opening of the washing tub 200 or the through holes on the barrel wall, and the above structure can refer to the drum washing machine of the prior art.

[0053] The above-mentioned clothing treatment device also has an electrostatic atomization device 500 that can generate atomized particles. The electrostatic atomization device 500 has an air inlet 510 connected to the external space and an air outlet 520 connected to the air duct 300. The atomized particles generated by the electrostatic atomization device 500 are sent into the air duct 300 with the help of the air flow sucked from the outside and enter the water tub 100 with the circulating air flow. Exemplary: The built-in ion generator of the electrostatic atomization device 500 (such as Panasonic Nanoe water ion generator) can use the moisture in the air to generate nano-scale tiny atomized particles, which can penetrate deep into the fiber of clothing and achieve the purpose of removing the odor of clothing without washing. Of course, the electrostatic atomization device 500 proposed in the embodiment of the present invention is not limited to clothing deodorization. According to different product requirements, carrying different types of electrostatic atomization devices 500 can also achieve other clothing care functions such as sterilization and wrinkle removal. And the above-mentioned deodorization and sterilization operations are not limited to clothing, but are also applicable to the cleaning and maintenance of the water tub 100 and the washing tub 200.

[0054] In this embodiment, the air duct 300 is separated into a positive pressure zone and a negative pressure zone by the fan 400, and the air outlet 520 is connected to the negative pressure zone. Since the air pressure in the negative pressure zone is lower than the normal pressure, the outside air is sucked in from the air inlet 510 of the electrostatic atomization device 500 under the action of the pressure difference, and then blown into the negative pressure zone from the air outlet 520. The outside air has a higher flow rate and flow when passing through the electrostatic atomization device 500, so that more atomized particles can be released into the air duct 300. Exemplarily: an air inlet 110 is set on the front side of the water tub 100, and a return air outlet 120 is set on the rear side of the water tub 100. The fan 400 has an air inlet side 410 and an air outlet side 420 (taking an axial flow fan as an example, the air inlet side 410 and the air outlet side 420 are the two sides of the rotation axis direction of the axial flow fan). The air duct 300 includes a return air channel 310 and an air outlet channel 320. The return air channel 310 connects the air inlet side 410 and the return air outlet 120, and the air outlet channel 320 connects the air outlet side 420 and the air inlet 110. The air outlet 520 of the electrostatic atomization device 500 is connected to the return air channel 310. The side where the fan 400 inhales air when it is working is the air inlet side 410, and the air in the return air channel 310 is inhaled by the fan 400 to form a negative pressure area. The side where the fan 400 blows out air when it is working is the air outlet side 420, and the fan 400 blows out air into the air outlet channel 320 to form a positive pressure area in the air outlet channel 320; the circulating air flow in the air duct 300 is sent into the water tub 100 and the washing tub 200 through the air inlet 110, and the circulating air flow in the washing tub 200 returns to the air duct 300 through the return air port 120, forming an internal circulation of the air flow from the air duct 300, the water tub 100 to the washing tub 200.

[0055] Compared with simply sending air flow into the washing tub, the circulating air flow has stronger fluidity in the washing tub 200, thereby promoting the uniform attachment of the atomized particles to the clothes and allowing the newly generated atomized particles to be continuously sent into the washing tub 200 with the help of the air flow circulation, maintaining efficient care operations.

[0056] In this embodiment, the clothing processing device is also provided with an exhaust channel, which is used to connect the water tub 100 to the outside space during the care process. Part of the air in the water tub 100 is released to the outside through the exhaust channel, and the return air channel 310 of the air duct 300 can continuously inhale the outside air from the air inlet 510 of the electrostatic atomization device 500. When the outside air passes through the electrostatic atomization device 500, the atomized particles generated inside the electrostatic atomization device 500 are blown into the air duct 300 to ensure the release effect of the electrostatic atomization device 500, so that more atomized particles can enter the washing tub 200 during the care process to participate in the deodorization, sterilization and other care operations of the clothes.

[0057] As described above, the laundry treatment device of this embodiment is provided with a detergent box 600. The user puts the detergent in the detergent box 600 in advance. During the washing process, the external water impacts the detergent in the detergent box 600, so that the detergent is dissolved / foamed in the detergent box 600 to form a detergent solution, which is then passed into the water tub 100 and the washing tub 200 through the water inlet pipe. Due to structural and functional requirements, the detergent box 600 is connected to the external space. In this embodiment, the water tub 100 is provided with an exhaust port 130, and the exhaust port 130 is connected to the detergent box 600 through a pipeline to form the above-mentioned exhaust channel. The detergent box 600 is an existing component of the laundry treatment device, and the exhaust channel thus formed is more cost-effective.

[0058] Preferably, the exhaust port 130 is disposed at the rear side of the water tub 100, and the exhaust port 130 is located on the water tub 100 far from the air inlet 110 at the front side, thereby preventing some atomized particles blown in by the air inlet 110 from being directly blown out from the exhaust port 130 and causing waste.

[0059] Reference Figure 3 In one embodiment of the present invention, based on the clothes processing device described in the above embodiment: the clothes processing device is provided with a drain valve 700, a drain port 140 is provided at the bottom of the water tub 100, and the drain port 140 is connected to the drain valve 700 through a pipeline. In some clothes processing programs (such as a dehydration program), when the drain valve 700 is opened, the water at the bottom of the water tub 100 can be drawn out and discharged from the drain port 140. During the care process, the drain port 140 is connected to the drain valve 700 through a pipeline to form an exhaust channel. When the drain valve 700 is opened, the drain port 140 can be connected to the external space, and part of the air in the water tub 100 can be released to the external space through the drain port 140 and the drain valve 700. The drain valve 700 is an existing component of the clothes processing device, and the exhaust channel thus formed is more cost-saving, and the water tub 100 does not need to open a separate exhaust port for care exhaust.

[0060] In one embodiment of the present invention, based on the clothing processing device described in the above embodiment: the clothing processing device also includes a control valve for controlling the opening and closing of the exhaust channel, so that the exhaust channel can be opened or cut off according to actual needs. For example, the exhaust channel is opened during the care process, and the exhaust channel is cut off in other clothing processing programs to prevent the fluid in the barrel from overflowing.

[0061] It should be noted that: the clothing processing device usually also has a door, which is arranged on the front side of the machine body for opening and closing the opening on the front side of the water tub. In some other embodiments of the present invention, the exhaust channel is arranged on the door, and the water tub can also be connected to the outside space during the care process. It can be seen that the conception of the scheme described in the present invention is essentially to connect the space formed by the water tub closed by the door to the outside space through the exhaust channel, so that part of the air in the water tub can be discharged to the outside during the care process. The schemes that can achieve the above functions are all within the protection scope of the present invention.

[0062] Reference Figure 4 In one embodiment of the present invention, based on the clothes processing device described in the above embodiment: an air suction duct 800 is connected between the air outlet 520 of the electrostatic atomization device 500 and the return air channel 310 of the air duct 300.

[0063] During the washing process of the clothes processing equipment, a large amount of foam is generated in the water tub 100 and the washing tub 200. As the washing tub 200 operates, the foam, washing water and other fluids will be squeezed out and flow back into the return air channel 310 through the return air port 120. Since the air outlet 520 is connected to the return air channel 310, the foam, washing water and other fluids entering the return air channel 310 will threaten the electrostatic atomization device 500. For example, the reverse flow fluid enters the electrostatic atomization device 500 from the air outlet 520, destroys the atomized particles, and may cause a short circuit failure of the electrostatic atomization device 500.

[0064] The setting of the suction pipe 800 extends the distance between the air outlet 520 and the return air channel 310. When backflow occurs, the reverse path is extended, making it difficult for the backflow fluid to flow to the air outlet 520; the above-mentioned suction pipe 800 is also provided with a non-return structure for preventing the fluid from backflowing into the electrostatic atomization device 500, and the non-return structure includes at least one non-return member 900, which has an open state allowing the forward fluid in the suction pipe 800 (the outside air carrying the atomized particles) to pass through and a closed state preventing the backflow fluid in the suction pipe 800 (the washing fluid, such as foam, washing water, which flows back into the return air channel 310 from the return air port 120) from passing through. The specific structure can rely on a baffle that is self-closing due to gravity, a one-way valve, etc. The setting of the non-return structure enhances the non-return effect of the suction pipe 800. When the nursing operation is implemented, the non-return structure is opened to keep the suction pipe 800 unobstructed, so that the outside air carrying the atomized particles is sucked into the return air channel 310 through the suction pipe 800.

[0065] As a preferred embodiment, the anti-return structure includes two anti-return members 900 arranged at intervals and a anti-return cavity 810 surrounded by the two anti-return members 900 in the air suction pipe 800. When the two anti-return members 900 are in a closed state, the anti-return cavity 810 is a closed space. Compared with the conventional arrangement of two check pieces 900, the present solution further forms a check cavity 810 between the two check pieces 900, and when the two check pieces 900 are in a closed state, the check cavity 810 is a closed space. In the reverse direction of the air suction pipe 800, the first check piece 900 plays a first check effect. If the reverse flow fluid enters the check cavity 810 through the first check piece 900, since the check cavity 810 is a closed space, as the reverse flow fluid enters, the air pressure in the check cavity 810 will increase, thereby preventing the reverse flow fluid from continuing to move forward in the reverse direction. The check cavity 810 plays a second check effect. If the reverse flow fluid reaches the second check piece 900, the second check piece 900 plays a third check effect. The above-mentioned triple check greatly enhances the check ability of the check structure.

[0066] The above-mentioned two anti-return parts 900 are preferably arranged at both ends of the suction pipe 800, and the anti-return cavity 810 formed thereby is close to the length of the entire suction pipe 800, maximizing the space of the anti-return cavity 810 and achieving better anti-return effect; of course, the anti-return cavity 810 can also be formed in the upstream section, midstream section, downstream section and other parts of the suction pipe 800 in the downstream direction.

[0067] Based on the above scheme, it is more preferred that: the check cavity 810 is inclined from low to high in the countercurrent direction. On the one hand, the climbing resistance of the countercurrent fluid is increased, and the check effect is better. On the other hand, the check cavity 810 is inclined from high to low in the downstream direction, reducing the flow resistance of the downstream fluid, such as the outside air carrying the atomized particles can more smoothly enter the return air channel 310 through the suction pipe 800.

[0068] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
