Description

[Technical Field]

[0001] [CROSS-REFERENCE TO RELATED APPLICATIONS] This application claims priority from a Chinese patent filed with the State Intellectual Property Office of the People's Republic of China on February 17, 2023, bearing application number 202320309263.5 and entitled "Clothing Treatment Equipment," the entire contents of which are incorporated herein by reference.

[0002] The present application relates to the technical field of household appliances, and in particular to clothing treatment equipment. [Background technology]

[0003] With the improvement of people's living standards and the continuous improvement of scientific and technological levels and product performance, people have more and more requirements for the functions of household appliances, thereby meeting the increasing usage needs at home and reducing manpower.

[0004] Laundry, one of the most time-consuming physical tasks at home, involves the entire laundry process, including washing, hanging to dry, storing, and organizing. Traditional washing machines can only perform the washing function, and sun-drying, drying, and storing still require manual labor. The newly released washer-dryers combine washing and drying functions, can be started with the push of a button, and can dry clothes after washing, greatly reducing the labor required for hanging to dry and storing.

[0005] The inventors discovered that conventional drying systems for washing machines and dryers use a moisture absorption assembly (evaporator or heat pump) to heat and absorb the moist air in the drum of the washing machine and dry the clothes. The resulting high-temperature air is then returned to the drum of the washing machine and dried, thereby evaporating the moisture from the clothes. However, the overall temperature of the conventional evaporator or heat pump is constant, and during the evaporation of the moist air, the moisture absorption capacity of the moisture absorption assembly for the moist air decreases, resulting in low moisture absorption efficiency, long drying times, and high power consumption. In particular, in environments with relatively low air temperatures, the temperature of the moist air also decreases, making it difficult for the evaporator temperature to reach the moisture absorption temperature, resulting in a further decrease in moisture absorption efficiency, longer drying times, and higher power consumption.

DETAILED DESCRIPTION OF THE INVENTION

[0023] In order to further clarify the objectives, technical solutions and advantages of the present application, the present application will be described in more detail below in conjunction with specific embodiments and with reference to the drawings. It should be understood that these descriptions are merely exemplary and do not limit the scope of the present application. In the following description, descriptions of known structures and techniques will be omitted to avoid unnecessary confusion of the concepts of the present application.

[0024] A first aspect of the present application provides a clothing treatment facility, which includes a moisture absorption and desorption member 10 and a heat pump heating assembly, as shown in Figures 1 to 4. The moisture absorption and desorption member 10 is connected to a drum 20, and is used to adsorb moisture in a wet airflow from the drum and send the generated dry airflow into the drum, while the heat pump heating assembly is connected to the moisture absorption and desorption member and is used to send a dry regenerated airflow to the moisture absorption and desorption member, thereby desorbing moisture from at least a portion of the moisture absorption and desorption member and restoring moisture absorption capacity to the moisture absorption and desorption member, wherein the moisture absorption and desorption member is installed above or below the drum, and the plane on which the moisture absorption and desorption member is located is parallel to the rotation axis of the drum. The moisture absorption and desorption member 10 can be made of, for example, a material with excellent moisture absorption properties, and can adsorb moisture in the wet airflow from the drum 20. The resulting dry airflow is then sent to the drum. The dry circulating airflow enters the drum through the drum air inlet and fully contacts the clothes, improving drying efficiency and reducing energy consumption. The heat pump heating assembly can include a compressor, a condenser 40, and an evaporator 30, which are connected in sequence via copper pipes to form a heat pump circulation system. A refrigerant is disposed within the copper pipes, and the refrigerant exchanges heat with the external regenerated airflow through the flow of the refrigerant. After exchanging heat with the heat pump heating assembly, the regenerated airflow becomes a relatively dry and high-temperature airflow, which can desorb at least some moisture from the moisture absorption and desorption member and at least partially restore the moisture absorption capacity of the moisture absorption and desorption member. Therefore, in an embodiment of the present application, a circulation regeneration function is added to the moisture absorption and desorption member 10 to continuously maintain the moisture absorption capacity of the moisture absorption and desorption member 10, facilitating continuous and efficient dehumidification and drying, thereby saving power and time. The direction of arrow 1 shown in FIG. 1 is the flow direction of the wet airflow from inside the drum 20, and the direction of arrow 2 shown in FIG. 1 is the flow direction of the regeneration airflow.

[0025] In some embodiments, the moisture absorbing and releasing member 10 is installed horizontally above or below the drum 20, and the plane on which the moisture absorbing and releasing member 10 is located is installed parallel to the rotation axis of the drum 20, making the overall structure of the clothing treatment equipment compact and reducing the space it occupies.

[0026] In some embodiments, the moisture absorption and desorption member includes a turntable housing having a partition member therein that divides the turntable housing into at least a moisture absorption region and a regeneration region, and a turntable 120 housed within the turntable housing and rotatable relative to the turntable housing, where the moisture absorption region is in communication with the drum and the regeneration region is in communication with the heat pump heating assembly. The turntable 120 can be made of a material with excellent moisture absorption performance, such as zeolite, lithium chloride, silica gel, modified silica gel, or 13X (sodium X-type) molecular sieve. Specifically, the moisture absorption and desorption member can further include a drive assembly, which can include a motor that can drive and rotate the turntable 120. The moisture absorption area can introduce moist airflow from inside the drum 20, which becomes a dry circulating airflow after passing through the turntable 120 and then enters the drum again. The regeneration area can introduce a hot and dry regeneration airflow to desorb moisture from a portion of the turntable 120. Therefore, as the turntable 120 continuously rotates in the circumferential direction, it circulates through the moisture absorption area and the regeneration area, thereby continuously completing the moisture adsorption and desorption processes.

[0027] In some embodiments, the heat pump heating assembly includes an evaporator 30 communicating with the regeneration zone for condensing the regeneration airflow discharged from the regeneration zone to form a relatively low-temperature, dry regeneration airflow, and a condenser 40 communicating with the evaporator 30 for heating the relatively low-temperature, dry regeneration airflow and discharging it into the regeneration zone, desorbing moisture from at least a portion of the turntable 120, and restoring moisture absorption capacity to the turntable 120. The regeneration airflow passes through the regeneration zone and desorbs moisture onto the turntable 120, becoming a high-temperature, high-humidity regeneration airflow. The high-temperature, high-humidity regeneration airflow enters the evaporator 30 for heat exchange, condensing and removing moisture from the high-temperature, high-humidity regeneration airflow to obtain a low-temperature, dry regeneration airflow. The low-temperature, dry regeneration airflow enters the condenser 40 and is heated to obtain a high-temperature, dry regeneration airflow, which then enters the regeneration zone and partially desorbs moisture onto the turntable 120 as it rotates in the regeneration zone, repeating this cycle.

[0028] In some embodiments, the turntable housing includes a first turntable housing 111 (i.e., the upper turntable housing) and a second turntable housing 112 (i.e., the lower turntable housing). For example, the turntable housing may have a circular structure, and a first partition member 1121 may be provided along the radial direction of the second turntable housing 112 to divide the second turntable housing 112 into a first moisture absorption area and a first regeneration area, both of which may be substantially sector-shaped spaces. The first turntable housing 111 may be provided with a second partition member 1111 that divides the first turntable housing 111 into a second moisture absorption area and a second regeneration area. The second partition member 1111 is disposed opposite the first partition member 1121, and the turntable 120 is located between the second partition member and the first partition member. The first and second moisture absorption areas are symmetrically arranged on the side of the turntable 120, and similarly, the first and second regeneration areas are symmetrically arranged on the side of the turntable 120. For example, a groove is provided in the first turntable housing 111 or the second turntable housing 112, and a sealing strip is installed in the groove to achieve sealing when the first turntable housing 111 and the second turntable housing 112 are engaged and connected. The area of ​​the moisture absorption area can be set larger than the area of ​​the regeneration area, so that most of the turntable 120 is located in the moisture absorption area, thereby further improving the moisture absorption efficiency and moisture absorption effect of the turntable 120. The second partition member 1111 and the first partition member 1121 can both be arranged to protrude from the inner walls of the first housing 111 of the turntable and the second housing 112 of the turntable, and it is preferable that the height of the second partition member 1111 and the first partition member 1121 does not interfere with the rotational sealing of the turntable 120, thereby preventing the wet circulation airflow and the regeneration airflow discharged into the drum from intersecting with each other.

[0029] In some embodiments, it is preferable that the clothing processing equipment further includes a regeneration housing to uniformly deliver the high-temperature, dry regeneration airflow to the turntable 120 and improve its ability to quickly desorb moisture. A regeneration housing mounting portion 50 is provided in the second regeneration area of ​​the first turntable housing 111, and the regeneration housing can be attached to the regeneration housing mounting portion of the first turntable housing 111. The regeneration housing is located on one side of the turntable 120, thereby desorbing moisture from the portion of the regeneration area corresponding to the turntable. Of course, the regeneration housing need not be provided; the first and second regeneration areas can be symmetrically installed on the first and second turntable housings 111 and 112. Here, the regeneration housing has an airflow space for forming a third airflow path, and a gap for forming a fourth airflow path is provided between the other side of the turntable 120 and the inner wall of the first regeneration area of ​​the second turntable housing 112. The regeneration housing has a fan-shaped structure that roughly corresponds to the shape of the second regeneration area and can be located above and adjacent to the turntable 120. An air distribution plate is provided within the regeneration housing, and multiple vents can be provided on the air distribution plate to ensure that the hot, dry regeneration airflow entering the third airflow passage is uniformly distributed to the turntable 120, passing through the turntable 120 from top to bottom, and reaching the fourth airflow passage. As the turntable 200 rotates in the regeneration area, the regeneration airflow heats that portion of the turntable 120, rapidly desorbing moisture from that portion. The regeneration airflow then carries the moisture away and enters the evaporator 30, where it condenses to form a relatively cool, dry regeneration airflow, which then enters the condenser 40 for heating, resulting in a hot, dry regeneration airflow that enters the third airflow passage, circulating back and forth in this manner. This allows the turntable 120 to always have good moisture absorption capacity, thereby improving the efficiency and effectiveness of moisture absorption. Specifically, a sealing pad 510 is provided between the regeneration housing and the first housing 111 of the turntable to prevent the regeneration airflow from escaping, achieve a certain sealing effect, and prevent heat loss at the same time.

[0030] In some embodiments, in the second moisture absorption area, there is a gap between the top surface of the turntable 120 and a portion of the inner wall of the first housing 111 of the turntable to form a first air flow passage, and in the first moisture absorption area, there is a gap between the bottom surface of the turntable 120 and a portion of the inner wall of the second housing 112 of the turntable to form a second air flow passage, the second air flow passage or the first air flow passage being connected to the drum exhaust port, and the first air flow passage or the second air flow passage being connected to the drum intake port, so that the wet airflow in the drum 20 passes through the second air flow passage or the first air flow passage and passes through the turntable 120 to reach the first air flow passage or the second air flow passage. In an exemplary embodiment, the wet circulating airflow discharged from the drum enters and diffuses into the second airflow passage, and the wet circulating airflow passes through the turntable 120 from bottom to top. The turntable 120 adsorbs moisture in the wet circulating airflow and transforms it into a dry circulating airflow. The dry circulating airflow enters the drum through the drum inlet and fully contacts the clothes, improving drying efficiency and reducing energy consumption. This embodiment uses the turntable 120 to adsorb moisture in the wet circulating airflow, thereby avoiding the reduced moisture absorption capacity for wet air that would be caused by using an evaporator.

[0031] In some embodiments, the condenser 40 is connected to the drum air inlet and the moisture absorption area, respectively, so that the airflow from the moisture absorption area passes through the turntable 120 to reach the first airflow passage or the second airflow passage and enters the condenser, which is used to preheat the generated dry airflow before sending it to the drum. The condenser in the heat pump heating assembly is used to preheat the generated dry airflow before sending it to the drum, and of course, the condenser may be replaced with a heater, which increases the temperature of the dry airflow and allows it to fully contact the clothes, thereby improving drying efficiency.

[0032] In some embodiments, the drying apparatus further includes a first switching mechanism 60 located between the condenser and the turntable housing, the first switching mechanism being used to control communication between the condenser and the moisture absorption region or cut off communication. An exhaust pipe 1112 is provided in the first housing 111 of the turntable, and a first switching mechanism is attached to the connection point between the exhaust pipe 1112 and the air inlet of the condenser 40. The first switching mechanism may be an electromagnetic valve, and the connection point between the exhaust pipe 1112 and the air inlet of the condenser 40 can be cut off by controlling the first switching mechanism. This allows the wet airflow from inside the drum to reach the moisture absorption region, pass through the turntable 120 from top to bottom (or bottom to top), become a dry airflow, and then directly discharge to the atmosphere, forming an open circuit. Alternatively, by controlling the first switching mechanism, the connection point between the exhaust pipe 1112 and the air inlet of the condenser 40 can be made to communicate, so that the wet airflow from inside the drum reaches the moisture absorption area, passes through the turntable 120 from top to bottom (or bottom to top), becomes a dry airflow, enters the condenser to be heated, and then enters the drum, forming a closed-circuit circulating airflow.

[0033] In some embodiments, the drying apparatus further includes a second switching mechanism 70, which is located between the evaporator 30 and the condenser 40 and is used to control communication between the evaporator and the condenser. The second switching mechanism may be a solenoid valve, which is provided at a connection between the air outlet of the evaporator 30 and the air inlet of the condenser 40. By controlling the second switching mechanism, the connection between the air outlet of the evaporator 30 and the air inlet of the condenser 40 can be blocked. After the high-temperature, high-humidity regeneration airflow is condensed and dehydrated, a low-temperature, dry regeneration airflow can be obtained and directly discharged into the atmosphere, forming an open circuit. Alternatively, by controlling the second switching mechanism, the connection point between the air outlet of the evaporator 30 and the air inlet of the condenser 40 can be made to communicate, and the high-temperature, high-humidity regeneration airflow is condensed and dehydrated to obtain a low-temperature, dry regeneration airflow, which is sent to the condenser 40, heated, enters the regeneration area, passes through the turntable 120 from top to bottom, and then enters the evaporator 30, thereby forming a closed-circuit regeneration airflow.

[0034] In some embodiments, the drying device further includes a first hard member 51 and a first flexible member 52 adjacent to the turntable, which are stacked in order on a first partition member 1121, and a second hard member 53 and a second flexible member 54 adjacent to the turntable, which are stacked in order on a second partition member 1111, wherein the first hard member and / or the second hard member have a groove for accommodating the first flexible member and / or the second flexible member in an orientation facing the turntable, and the first flexible member and / or the second flexible member are placed within the groove and protrude from the edge of the groove. The first flexible member 52 or a portion thereof is embedded in the groove of the first hard member 51, and a tensile force generated by the pressing and deformation of the first flexible member 52 causes the first flexible member 52 to be fixed opposite the first hard member 51, and the first hard member 51 can be further fixed to the first partition member with screws. Similarly, the second flexible member 54 can be fixed to the second hard member 53, and the second hard member 53 can be further fixed to the second partition member with screws. The first flexible member 52 and the second flexible member 54 are preferably attached to the upper and lower surfaces of the turntable 120 without contacting each other, i.e., they do not interfere with the flexible members facing the upper and lower surfaces during rotation. At the same time, they are sufficiently close to each other and located on the same surface of the turntable 120, which can maintain the relative isolation of the airflow in the playback area and the moisture absorption area located on both sides of the flexible member, thereby achieving a dynamic sealing effect. The first flexible member 52 and the second flexible member 54 may be soft adhesive or slivers, and the first flexible member may employ the same material as the second flexible member or may be different.

[0035] In some embodiments, the first flexible member 52 and the second flexible member 54 contact the surface of the turntable 120, respectively, or a gap of 0.2 to 2 mm is provided between the first flexible member 52 and the second flexible member 54 and the turntable 120. Naturally, the first flexible member 52 and the second flexible member 54 can alternatively contact or even interfere with the upper and lower surfaces of the turntable 120, respectively, to achieve a better sealing effect, but this will correspondingly increase the rotation resistance of the turntable 120. In this embodiment, a relatively preferred preset gap range is provided between the first flexible member 52 and the second flexible member 54 and the upper and lower surfaces of the turntable 120. Within this range, the first flexible member 52 and the second flexible member 54 do not contact the turntable 120, allowing the airflow in the playback area and the moisture absorption area to be relatively isolated, thereby achieving a certain degree of sealing effect and thereby achieving a dynamic sealing effect. It is also possible to prevent friction between the first flexible member 52 and the second flexible member 54 and the rotating disk 120, thereby reducing the rotation resistance of the rotating disk 120.

[0036] In some embodiments, the laundry treatment equipment may include a drum and a dryer. The drum is provided with a drum air inlet and a drum air outlet, which are respectively located at opposite ends of the drum rotation axis, and the drum air inlet and / or drum air outlet are higher than the drum rotation axis, or the drum air inlet and / or drum air outlet are higher than the highest water level in the drum. The dryer may include a moisture absorption and desorption member 10 and a heat pump heating assembly. The moisture absorption and desorption member 10 may include a turntable 120. Specifically, the second airflow passage or the first airflow passage communicates with the drum air outlet, and the first airflow passage or the second airflow passage communicates with the drum air inlet. The wet airflow in the drum passes through the second airflow passage or the first airflow passage and the turntable 120 to reach the first airflow passage or the second airflow passage, forming a dry airflow. Here, the turntable 120 is used to absorb moisture in the wet airflow from the drum. The moisture absorption and desorption member 10 can be made of, for example, a material with excellent moisture absorption properties, and can adsorb moisture in the wet airflow from the drum 20. The resulting dry airflow is then sent to the drum. The dry circulating airflow enters the drum through the drum air inlet and fully contacts the clothes, improving drying efficiency and reducing energy consumption. The heat pump heating assembly can include a compressor, a condenser 40, and an evaporator 30, which are connected in sequence via copper pipes to form a heat pump circulation system. A refrigerant is installed in the copper pipes, and the refrigerant flows through the refrigerant to exchange heat with the regenerated airflow. After exchanging heat with the heat pump heating assembly, the regenerated airflow becomes a dry, high-temperature airflow, which can desorb at least a portion of the moisture from the moisture absorption and desorption member and restore its moisture absorption capacity. Therefore, in this embodiment, a circulation regeneration function is added to the moisture absorption and desorption member 10 to continuously maintain the moisture absorption capacity of the moisture absorption and desorption member 10, facilitating continuous and efficient dehumidification and drying, thereby saving power and time. The direction of arrow 1 shown in FIG. 1 is the flow direction of the wet airflow from inside the drum 20, and the direction of arrow 2 shown in FIG. 1 is the flow direction of the regeneration airflow.

[0037] In some embodiments, the drum exhaust and intake ports are all located above the maximum water level, thus eliminating the need to completely drain the wash water from the drum to start and operate the dryer, providing greater flexibility in selecting the timing of the dryer start-up operation.
