In addition, the technical features involved in the different implementations of this application described below can be combined with each other as long as they do not conflict with each other.

After research, it was found that the main reason for the aging of the drying module is that the heating module directly transfers heat to the shell, and the heat resistance of the shell is poor, which leads to the aging of the shell. In this regard, this application provides a drying module and a clothing processing device to solve this problem.

In some embodiments, the clothing processing device may be a washing and drying machine. Of course, the present disclosure is not limited thereto, and any other clothing processing device with a drying function should also be included in the scope of the present disclosure.

The following is a detailed description of the drying module and clothing processing device provided by the embodiment of this application through specific embodiments and their application scenarios in conjunction with the attached figures.

As shown in FIG. 1, in the first aspect of the embodiment of the present application, a drying module is provided, which may include: a housing 1 for accommodating a moisture absorption and dehumidification component, a mounting portion of a heating module 2 is disposed on the housing 1; a heating module 2, the heating module 2 includes a base and a heating element, and the base is connected and mounted to the mounting portion via a thermal buffer 3.

The drying module of the above embodiment is provided with a heat buffer 3 between the heating module 2 and the shell 1, so that the heat generated by the heating module 2 is buffered, and the high temperature is prevented from being directly transferred to the shell 1 and damaging it. The aging of the shell 1 is delayed, and the service life of the drying module is improved.

In this embodiment, the housing 1 for accommodating the moisture absorption and dehumidification components is an integrally divided housing 1, and a moisture absorption area and a dehumidification area are provided on the housing 1. The moisture absorption area and the dehumidification area are divided into at least two functional areas by at least two radial ribs. The installation part of the heating module 2 is provided in the dehumidification area of the housing 1, which is convenient for modular assembly of the heating module 2. The shape of the heating module 2 is adapted to the shape of the dehumidification zone. If the housing 1 is a circular structure, the dehumidification zone is a fan-shaped area; then the heating module 2 is a fan-shaped structure, including a space formed by upper and lower walls and two side walls along the radial direction, in which a base and a heating element under the base are arranged, and a thermostat installation portion extends outward from a side wall of the lower wall. An air hole is arranged on the base, and the wind blows radially through the base through the air inlet of the heating module 2, and blows downward from the air hole through the heating element and then flows to the rotor part of the moisture absorption zone, thereby forming an effect of heating and desorbing moisture from the rotor part of the moisture absorption zone. The heater is close to the base so as not to create a large resistance to the wind passing through the air hole; the heater is located directly below the air hole and slightly offset in the radial direction, because when the wind blows inward along the radius and passes through the air hole, it will have a speed in the direction of the radius indicated by the arrow, so setting a slight offset can allow the wind passing through the air hole to face the heater directly.

In some embodiments, the thermal buffer 3 includes: a heat insulating member 31; the heat insulating member 31 is arranged around the base to prevent the high temperature of the heating element from being directly transmitted to the housing 1.

In this embodiment, the heat insulating member 31 is arranged around the base, that is, between the heating module 2 and the shell 1. In this way, the heat insulating member 31 can block the heat generated by the heating module 2, prevent the high temperature generated by the heating module 2 from being directly transmitted to the shell 1, and avoid the high temperature directly being transmitted to the shell 1 to damage it. The aging of the shell 1 is delayed, and the service life of the drying module is improved.

In some embodiments, the material of the thermal insulation member 31 is a heat-insulating material or a metal material.

In this embodiment, the thermal insulation material is a general term for heat preservation and cold preservation materials, and its properties may include: low thermal conductivity; stable material performance with a clear thermal conductivity equation, and a large temperature application range; low density; able to withstand certain vibrations and have certain mechanical strength; good chemical stability and no corrosion; good waterproof performance and low moisture absorption. There are few combustible components and it should have the characteristics of self-extinguishing and non-flammability. In order to reduce costs, metal materials can also be used, such as hardware, which not only has a certain heat insulation effect, but also has a long service life and good thermoplasticity.

In some embodiments, the thermal buffer 3 further includes: a sealing pad 32; the sealing pad 32 is coated on the outside of the thermal insulation 31; or the sealing pad 32 is respectively arranged on both sides of the thermal insulation 31, that is, the heating module 2, the sealing pad 32, the thermal insulation 31, the sealing pad 32, and the shell 1 are arranged in sequence; or the sealing pad 32 is only arranged between the thermal insulation 31 and the shell 1.

In this embodiment, the sealing pad 32 can be arranged along the heat insulating member 31. In order to further prevent heat dissipation, the heat can be transferred along a predetermined path, while ensuring efficient use of heat and preventing heat from damaging the housing 1 and other modules.

In some embodiments, the material of the sealing pad 32 is a foam material, a silicone material or a soft rubber material.

In this embodiment, the material of the sealing pad 32 is selected from some relatively soft and elastic materials, which can be changed with the structural changes of the heat insulation member 31, and can further increase the airtightness of the dehumidification area.

In some embodiments, a preset gap is left between the setting position of the sealing pad 32 and the bottom of the mounting portion.

In this embodiment, a certain preset gap is left to reduce the resistance between the drying module and other modules. For example, a rotating wheel can be set under the drying module. If the sealing pad 32 is completely in contact with the rotating wheel, the rotating resistance of the rotating wheel will increase, which will not only affect the rotation of the rotating wheel, but also reduce the service life of the rotating wheel.

In some embodiments, the preset gap is 0.2 mm to 5 mm.

In this embodiment, a preferred preset gap range is provided, within which the sealing pad 32 will not contact the adjacent device or module, and will also have a certain sealing effect to prevent heat dissipation. After repeated research and experiments, the preset gap is controlled at 0.6mm to 0.8mm, which has a better effect.

In some embodiments, the material of the housing 1 is plastic.

In this embodiment, the shell 1 that accommodates the moisture absorption and dehumidification components can be made of plastic material, because the cost of plastic material is relatively low, and it is not easily corroded by water vapor, and has a longer service life.

The drying module in the above embodiment not only includes the housing 1 and the heating module 2, but also includes moisture absorption and dehumidification components inside the housing 1.

In some embodiments, the moisture absorption and discharge structure is a breathable structure.

In this embodiment, the moisture absorption and dehumidification component is set as a breathable structure, which can increase the contact area between water vapor and the moisture absorption and dehumidification component, and better absorb and dehydrate the water vapor.

In some embodiments, the material of the moisture absorption and dehumidification component is silicone, modified silicone or sodium X-type molecular sieve.

The material of the moisture absorption and dehumidification component in this embodiment can better absorb water vapor.

A first partition can be provided between the moisture absorption and discharge component and the upper shell, and a second partition can be provided between the moisture absorption and discharge component and the lower shell; the first partition and the second partition separate the interior of the shell into an independent and relatively closed air path. This prevents the water vapor in the dehumidification area from escaping to the outside and affecting the drying effect of the clothes. In addition, this structure is simple and compact, occupies little space, and is conducive to the modular design of the clothing treatment device.

The shapes of the upper and lower housings in this embodiment can be designed according to the actual module structure of the clothes processing device, as long as they include two functional areas, the dehumidification area and the regeneration area. The shapes of each functional area can also be designed according to actual needs, and can be square, triangular, circular, or fan-shaped, as long as the dehumidification area and the regeneration area are consistent in shape and arranged correspondingly. The fan-shaped design of this embodiment can more effectively and reasonably utilize space. In addition, the moisture absorption and dehumidification component is arranged between the upper shell and the lower shell and can play the moisture absorption and dehumidification function. This application does not limit the shape of the moisture absorption and dehumidification component. It can be a polygon such as a triangle or a square, or a wheel shape. The wheel-shaped moisture absorption and dehumidification component design can make the wheel rotate to use the dry area to absorb water vapor in the dehumidification area, and then rotate to the dehydration area to remove moisture, so as to remove moisture in the water vapor in a cyclic reciprocating manner, thereby achieving the effect of drying clothes.

In some embodiments, the first partition is fixed to the upper shell by screws; the second partition is fixed to the lower shell by screws.

In this embodiment, the first partition is fixed to the upper shell by screws, and the second partition is fixed to the lower shell by screws. This ensures that the first partition and the second partition are stable and firm, will not be affected by high-speed airflow, and will not be displaced by the movement and friction of the moisture absorption and dehumidification components, further ensuring airtightness.

In some embodiments, the first partition includes a first hard member and a first flexible member stacked and arranged, and the first flexible member is arranged close to the moisture absorption and dehumidification member; the second partition includes a second flexible member and a second hard member stacked and arranged, and the second flexible member is arranged close to the moisture absorption and dehumidification member; the shapes of the first hard member, the first flexible member, the second flexible member and the second hard member are consistent with the shape of the dehumidification area.

In this embodiment, a flexible member is provided near the moisture absorption and discharge member to prevent the moisture absorption and discharge member from rubbing against the first partition and the second partition when the moisture absorption and discharge member moves, thereby reducing the wear of the moisture absorption and discharge member.

In some embodiments, a gap of 0.2 mm to 5 mm is left between the first flexible member and the second flexible member and the moisture absorption and discharge member.

In this embodiment, a preferred preset gap range is provided, within which the first partition and the second partition will not contact the adjacent moisture absorption and dehumidification components, and a certain sealing effect will be achieved, preventing the escape of water vapor and the friction between the moisture absorption and dehumidification components and the first partition and the second partition. After repeated research and experiments, the preset gap is controlled at 0.6mm to 0.8mm, and the best effect is achieved.

As shown in Figure 2, in the second aspect of the embodiment of the present application, a clothing processing device is provided, which may include: a drum and a drying module of any one of the first aspects of the embodiment; the drying module 10 is arranged on the outer drum 201 of the drum 20.

Since the clothes processing device of this embodiment includes any drying module of the first aspect, the effects that can be achieved by the drying module in the above embodiments can also be achieved by this clothes processing device, and no repetition is required here.

The above describes the embodiments of the present application in conjunction with the attached drawings, but the present application is not limited to the above specific embodiments, which are only illustrative and not restrictive. Under the inspiration of the present application, ordinary technicians in this field can make many forms without departing from the purpose of the present application and the scope of protection of the patent application, all of which are within the protection of the present application.
